Laparoscopic splenectomy for treatment of patients with idiopathic thrombocytopenic purpura

BACKGROUND: Laparoscopic splenectomy (LS) is one of the advanced laparoscopic procedures that benefit most from minimally invasive surgery. This study was undertaken to compare the operating time, blood loss, length of hospital stay, and platelet count response for patients with idiopathic thrombocytopenic purpura (ITP) undergoing open splenectomy (OS) versus LS. METHODS: We performed OS in 20 cases before 1992 and LS in 14 cases after 1993 for the treatment of ITP. RESULTS: The operating time was significantly shorter for OS than for LS (126 +/- 52 min versus 203 +/- 83 min, p < 0.01). Blood loss was less for OS than for LS (321 +/- 264 ml versus 524 +/- 648 ml, p = 0.287). None of the patients who underwent LS were converted to open surgery. Accessory spleens were found in four OS patients (20.0%) and four LS patients (28.6%). The postoperative hospital stay was significantly longer for OS patients than for LS patients (15.2 +/- 5.8 days versus 8.9 +/- 2.9 days, p < 0.0005). No significant difference was noted in the long-term results of splenectomy. CONCLUSIONS: Compared with OS, LS required more operating time, had the potential to cause greater blood loss, had a comparable incidence of accessory spleen and response rate, and appeared to shorten the postoperative stay.     

A comparison of robotic-assisted splenectomy and laparoscopic splenectomy for children with hematologic disorders

IntroductionLaparoscopic splenectomy (LS) is the standard of care for hematologic disorders requiring splenectomy. Less is known about the outcomes following robotic-assisted splenectomy (RS) for this indication. Our aim was to describe outcomes of RS to LS in pediatric patients with hematologic disorders in our institution.MethodsA single institution retrospective review was performed of pediatric patients undergoing LS vs. RS from 2014 to 2019. Patient demographics, diagnosis, spleen size, hospital length of stay (LOS), operative time, post-operative opioid use, and hospital charges were evaluated. Standard univariate analyses were performed.ResultsTwenty-four patients were included in the study (14 LS, 10 RS). The mean spleen size at the time of surgery was larger in the RS group compared to LS (14.5 cm vs. 12.2 cm, p = 0.03). Operative time between the two cohorts was comparable (RS 140.5 vs LS 154.9 min). Median LOS for RS was shorter than LS (2.1 vs. 3.2 days, p = 0.02). Cumulative postoperative opioid analgesic requirements were not significantly different between the groups (17.4 mg vs. 30.5 mg). The median hospital charges, including the surgical procedure and hospital stay were higher in the RS group ($44,724 RS vs $30,255 LS, p = 0.01).ConclusionRobotic splenectomy is a safe and feasible option for pediatric patients with hematologic disorders, and was associated with decreased LOS but higher charges compared to laparoscopic splenectomy. Further studies are required to delineate the optimal use and potential benefits of robot-assisted surgical techniques in children.Level of EvidenceII.     

Laparoscopic versus open splenectomy in children

BACKGROUND: The authors have reviewed their initial experience with laparoscopic splenectomy (LS) to identify the indications, success rate, and complications associated with this procedure compared with a series of children undergoing open splenectomy (OS) during the same time period. METHODS: The records of 51 children who underwent splenectomy from 1993 through 1998 were reviewed retrospectively. RESULTS: Thirty-five patients aged 1 to 17 years (mean, 9.4 years) underwent LS for the following indications: ITP (n = 20), sickle cell disease or thalassemia (n = 6), hereditary spherocytosis (n = 5), other hematologic disorders (n = 4). Seventeen patients aged 2 to 17 years (mean, 11.8 years) underwent OS during the same time period for ITP (n = 4), sickle cell disease or thalassemia (n = 4), hereditary spherocytosis (n = 5), and other indications (n = 4). Concomitant cholecystectomy was performed in 4 of 35 LS and 4 of 17 OS. Accessory spleens were identified in 10 of 35 LS and 2 of 17 OS cases. Eleven spleens were enlarged in the LS group, and 8 were enlarged in the OS group. One LS required conversion to an open procedure because the spleen did not fit in the bag. No other cases were converted. Median estimated blood loss was 50 mL for both the LS and OS groups. The only intraoperative complication in the LS group was a splenic capsular tear, which had no effect on the successful laparoscopic removal of the spleen. No patient in either group required a blood transfusion. The LS patients had a shorter length of hospital stay (1.8 +/- 1 versus 4.0 +/- 1 day, P = .0001). Total hospital charges were not significantly different. Follow-up ranged from 6 to 40 months. One LS patient died 47 days postoperatively from unrelated causes. Two LS patients had recurrent ITP; accessory spleens were found in one and resected laparoscopically. CONCLUSION: LS in children can be performed safely with a low conversion rate (2.9%) and is associated with a shorter hospital stay and comparable total hospital cost when compared with OS.     

Laparoscopic versus open pediatric splenectomy for massive splenomegaly

Laparoscopic splenectomy (LS) has rapidly evolved into the technique of choice compared with open splenectomy (OS) because of the advantages of the minimally invasive approach. Splenomegaly increases the technical difficulties of LS. LS for massive splenomegaly has generally been found to fail in adults and children. With improvements in laparoscopic technique and accumulation of laparoscopic experience, however, concerns about completing the procedure in pediatric cases with even massive splenomegaly have been lowered. A retrospective review (April 1997-October 2009) of databases at 2 institutions identified 145 children undergoing splenectomy, 79 laparoscopic and 66 open. We defined splenic margin below the umbilicus or anteriorly extending over the midline as massive splenomegaly. By this definition, 22 cases of pediatric laparoscopic and 17 cases of open splenectomies for massive splenomegaly were performed. Perioperative and follow-up data of laparoscopic pediatric splenectomies were compared with those of open splenectomies, including operative time, bleeding, spleen size, complications, and hospital stay. There were no deaths, wound infections, or instances of pancreatitis. No accessory spleen was missed by laparoscopic; accessory spleens were missed in 2 patients in open splenectomies. The complication rate of laparoscopic versus open was 13.6% versus 41.2%. No subsequent surgery was necessary for dealing with complications both in laparoscopic and open series. Laparoscopic pediatric splenectomy for massive splenomegaly is a feasible, effective, and safe procedure and is associated with low morbidity and a short hospital stay.     

Hand-assisted laparoscopic splenectomy (HALS) in cases of splenomegaly

BACKGROUND: Laparoscopic splenectomy (LS) is considerably more difficult to perform when the spleen is enlarged. The new technique of hand-assisted designed technique aimed to assist laparoscopic surgery allows the surgeon to insert his or her hand into the abdomen while maintaining the pneumoperitoneum, thus recovering the tactile sensation lost in conventional laparoscopic surgery. Object: In this study, we compared the immediate results of conventional LS and hand-assisted LS (HALS) in cases of splenomegaly. METHODS: Between February 1993 and August 2001, 200 LS were attempted at two university hospitals. In 56 cases, splenomegaly (final spleen weight >700 g) was observed clinically or detected on radiological examination. We compared the first 36 patients operated on by conventional LS (group I) with the last consecutive 20 patients, who underwent HALS (group II). The study parameters were operative time, conversion rate, transfusion rate, morbidity and length of hospital stay. RESULTS: The groups were comparable in terms of age (58 +/- 13 [ranges, l9-82] vs 58 +/- 16 years [range, 44-84] (ns), diagnosis, and spleen weight (1425 +/- 884 [range, 700-3400]) vs 1753 +/- 1124 g [range, 720-4500] (ns). HALS was associated with less morbidity (36% vs 10%) (ns), a shorter operative time (177 +/- 52 [range, 95-300]) vs 135 +/- 53 min [range, 85-270] (p <0.009), and a shorter hospital stay (6.3 +/- 3.3 [range, 3-14]) vs 4 +/- 1.2 [range, 2-7] days (p <0.05). CONCLUSION: In cases of splenomegaly, HALS assisted laparoscopic surgery significantly facilitates the surgical maneuvers during LS while maintaining the advantages of a purely laparoscopic approach.     

Refining the selection criteria for laparoscopic versus open splenectomy for splenomegaly

BACKGROUND: Although laparoscopic splenectomy is considered the procedure of choice for patients with normal-sized spleens, the benefits are less clear in the presence of splenomegaly, which represents a heterogeneous patient population with a variety of underlying diseases. The aim of this study was to compare the outcomes of laparoscopic (LS) and open splenectomy (OS) for spleens between 15 and 25 cm in length in order to identify strategies for patient selection for the laparoscopic approach. STUDY DESIGN: The medical records of concurrent patients undergoing splenectomy for splenomegaly (>15 cm in the long axis) from 2000 to 2005 were reviewed at two hospitals. At one hospital, LS was performed unless the spleen was >25 cm in length, while the other hospital used OS exclusively. Demographic, intraoperative, and postoperative variables were compared for patients potentially eligible for LS. Data are expressed as median (interquartile range) and were analyzed by using nonparametric tests. A value P < 0.05 was considered statistically significant. RESULTS: Sixty-five laparoscopic and 25 open splenectomies were performed at the two hospitals, of which 34 were for splenomegaly. Five open cases involved spleens >25 cm and were excluded, leaving 18 LS (13 hand assisted) and 11 OS for further analysis. The groups were similar in comorbidity score, spleen length, hematologic diagnosis, and intraoperative blood loss. The open group was younger, included more females, and had a shorter operative time. Time to oral intake (1 vs. 2 days; P = 0.04) and length of hospital stay (3 vs. 6 days; P = 0.01) were shorter in the LS group. Postoperative complications occurred in 7 (39%) LS and 6 (55%) OS patients (P = 0.47); these were major in 3 LS patients and 1 OS patient (P = 1.0). All 3 major complications after LS occurred in the 3 patients with myelofibrosis and involved a conversion or reoperation by laparotomy for bleeding. CONCLUSIONS: Laparoscopic splenectomy confers benefit for most patients with splenomegaly between 15 and 25 cm, as it is associated with faster time to oral intake and a shorter hospital stay. Major morbidity after laparoscopic splenectomy was mostly related to surgery for myelofibrosis. These patients did not derive any benefit from the laparoscopic approach due to bleeding complications, requiring a conversion or relaparotomy.     

Laparoscopic versus open sigmoid colectomy for diverticulitis

This study compared laparoscopic with open sigmoid colectomy for patients with a diagnosis of diverticulitis. Increased use of less invasive techniques makes it vitally important to evaluate outcomes of these techniques as compared with standard open procedures. Patients undergoing sigmoid colectomy for diverticulitis without hemorrhage (code 56211) between January 1997 and December 2001 were reviewed. Two groups were identified: those undergoing open sigmoid colectomy and those undergoing laparoscopic sigmoid colectomy; American Society of Anesthesiologists (ASA) scores, operative time, intensive care unit (ICU) and hospital length of stay, morbidity/mortality, and hospital charges were compared. During the study period 271 sigmoid colectomies were performed for diverticulitis without hemorrhage: 56 laparoscopically and 215 with the standard open technique. Four patients required conversion from laparoscopic to open colectomy. Mean ASA scores were: open group 2.4; laparoscopic group, 1.9 (P < 0.001). Mean operative times were: laparoscopic group, 170 +/- 45 minutes; open group, 140 +/- 49 minutes (P < 0.001). In the open group 39 patients required transfer to the ICU; one patient in the laparoscopic group required transfer to the ICU. Average hospital lengths of stay for the open and laparoscopic groups were 9.06 and 4.12 days, respectively (P < 0.001). Complications were recorded in 57 (27%) of 215 patients who underwent an open procedure versus 5 (9%) of 56 patients who underwent laparoscopic sigmoid colectomy (P < 0.01). There were three deaths in the open group and none in laparoscopic group. Average total hospital charges were 25,700 dollars for open sigmoid colectomy and 17,414 dollars for laparoscopic colectomy. Laparoscopic sigmoid colectomy compares favorably with open sigmoid colectomy for patients with a diagnosis of diverticulitis.     

Laparoscopic versus open splenectomy in the pediatric population: a contemporary single-center experience

The purpose of this study was to compare a recent contemporaneous experience between laparoscopic (LS) and open (OS) splenectomy in children. All splenectomy cases between 1994 and 1999 at our institution were reviewed. The study included open and laparoscopic cases performed according to surgeon preference. Emergency splenectomies for trauma were excluded. The patient record was reviewed for the diagnosis, indications, postoperative length of stay, operative technique, postoperative complications, blood loss/blood transfusion, total amount of parenteral narcotics, and time to resumption of oral intake. Chi-square and t tests were used to compare measured differences for statistical significance. Between May 1994 and December 1999, 52 splenectomies were performed at Vanderbilt Children's Hospital. Of these, 45 were elective operations with 29 open and 16 laparoscopic procedures. During four OS and five LS operations a concomitant cholecystectomy was performed. The median patient age was 9.2 years (range 0.5 to 17.3). There was no statistical difference between the two groups in terms of age, weight, American Society of Anesthesiologists class, or estimated blood loss. There were no immediate postoperative complications in either group. There were no conversions from LS to OS. The mean duration of surgery was 264 minutes (LS) versus 169 minutes (OS) (P < 0.05). The average time to first oral intake was shorter in patients undergoing LS (1.1 vs 1.6 days, P < 0.05) and the mean postoperative length of stay was also shorter in the LS group (1.3 vs 3.1 days, P < 0.05). The use of postoperative intravenous narcotics (in morphine-equivalent doses) was significantly less in LS patients than in OS patients (7.5 mg or 0.15 mg/kg vs 46.9 mg or 1.5 mg/kg, P < 0.001), as was the need for PCA pump analgesia (90% in the OS group vs 25% in LS group, P < 0.01). Overall the average hospital charge (anesthesia fee, narcotics charge, and hospital room charge) was $5400 (range $4240-6250) in the OS group and $4950 (range $4450-6240) in the LS group (P < 0.05). Among the nine patients undergoing splenectomy with cholecystectomy, findings between the OS and LS groups were similar except for one late complication consisting of a diaphragmatic hernia in an LS patient. Both LS and OS with or without a concomitant procedure can be accomplished safely in children. LS appears to result in longer operative times but shorter lengths of stay, earlier first oral intake, and significantly fewer requirements for intravenous narcotics; all of these contribute to a reduction in hospital charges compared with the open operation.     

Laparoscopic splenectomy in children

To determine the safety and efficiacy of laparoscopic splenectomy (LS) in children, a retrospective review of our preliminary experience using LS was compared to results in patients who previously underwent open splenectomy (OS). From July 1993 to January 1995, we performed eight LS procedures in six children with hereditary spherocytosis (HS) and two with immune thrombocytopenic purpura (ITP). Laparoscopic cholecystectomy was simultaneously done in one case with HS. There were 4 males and 4 females who ranged in age from 5 to 15 years—an average age of 8.8 years. Two cases in the early series required a counterincision because of bleeding. Eleven patients who previously underwent OS in our department were used to compare demographics, operative courses, and surgical outcomes. The ages, genders, diseases, body weights, and spleen weights were comparable between LS group and OS groups. The operative time for the LS group was statistically longer than for the OS group (226±24 min vs 101±8 min, P<0.001). The estimated blood loss in the LS group was similar to that of the OS group (100±39 ml vs 73±11 ml, P=0.97). There were no peri- or postoperative complications in two groups. The postoperative hospital stay of LS group was statistically shorter than that of the OS (6.8±0.6 days vs 10.4±0.5 days, P<0.001). LS provided better cosmesis and minimized trauma in children over OS. LS appears to be a safe and effective procedure in children, and is useful in the management of pediatric patients with HS or ITP.Presented at the annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons (SAGES), Orlando, Florida, USA, 11–14 March 1995     

Effect of spleen size on splenectomy outcome

BACKGROUND: Laparoscopic splenectomy (LS) is gaining acceptance as an alternative to open splenectomy (OS). However, splenomegaly presents an obstacle to LS, and massive splenomegaly has been considered a contraindication. Analyses comparing the procedure with the open approach are lacking. The purpose of this study was to analyze the effect of spleen size on operative and immediate clinical outcome in a series of 105 LS compared with a series of 81 cases surgically treated by an open approach. METHODS: Between January 1990 and November 1998, 186 patients underwent a splenectomy for a wide range of splenic disorders. Of these patients, 105 were treated by laparoscopy (group I, LS; data prospectively recorded) and 81 were treated by an open approach (group II, OS analyzed retrospectively). Patients also were classified into three groups according to spleen weight: group A, <400 g; group B, 400-1000 g; and group C, >1000 g. Age, gender, operative time, perioperative transfusion, spleen weight, conversion rate, mode of spleen retrieval (bag or accessory incision), postoperative analgesia, length of stay, and morbidity were recorded in both main groups. RESULTS: Operative time was significantly longer for LS than for OS. However, LS morbidity, mortality, and postoperative stay were all lower at similar spleen weights. Spleens weighing more than 3,200 g required conversion to open surgery in all cases. When LS outcome for hematologic malignant diagnosis was compared with LS outcome for a benign diagnosis, malignancy did not increase conversion rate, morbidity, and transfusion, even though malignant spleens were larger and accessory incisions were required more frequently. Postoperative hospital stay was significantly longer in malignant than in benign diagnosis (5 +/- 2.4 days vs. 4 +/- 2.3 days; p < 0. 05). CONCLUSIONS: In patients with enlarged spleens, LS is feasible and followed by lower morbidity, transfusion rate, and shorter hospital stay than when the open approach is used. For the treatment of this subset of patients, who usually present with more severe hematologic diseases related to greater morbidity, LS presents potential advantages.     

Laparoscopic splenectomy

Background: The purpose of this study was to evaluate the outcome of patients undergoing laparoscopic splenectomy (LS) at the University of California, San Francisco. Methods: The medical records of the initial 52 unselected patients undergoing LS were reviewed and compared to 28 concurrently treated open splenectomy patients (OS). Results: Patients did not differ with regard to age, gender, body, or splenic weights. The operative time was longer in the LS patients (mean 196 vs 156 min), but the length of stay and duration of ileus were shorter in the LS group. For adult patients admitted exclusively for splenectomy, operative times did not differ between LS and OS and total hospital cost was less in the LS group (mean $8,939 vs $14,022). Six patients required conversion to OS, four occurring in the first 11 patients treated (overall conversion rate of 11%). Three patients died from complications related to their underlying disease. Two other major complications occurred. Complication rates and transfusion requirements did not differ between OS and LS patients. Conclusions: Laparoscopic splenectomy is a safe and effective alternative to open splenectomy for treatment of hematologic diseases in patients of all ages.

Introduction of laparoscopic splenectomy for the treatment of immune thrombocytopenic purpura

AIM OF THE STUDY: Was to evaluate retrospectively the outcomes and efficacy of the laparoscopic splenectomies for ITP patients, performed at our institution over a period of 7 years and to compare these results with those after open splenectomies. PATIENTS AND METHODS: We collected and analyzed data of 22 consecutive adult patients with ITP who underwent either laparoscopic (LS gr., n = 9) or open (OS gr., n = 13) splenectomy at Hospital of Kaunas University of Medicine between the years 1996 and 2002. The indications for splenectomy in these patients were unsuccessful treatment with corticosteroids or other medications and/or the requirement of high dosages of steroids for prolonged periods of time to maintain platelet count > 50 G/L before operation. Prior to surgery, all patients were treated with corticosteroids and/or intravenous immunoglobulin to raise the platelet count and to minimize the risk of intraoperative bleeding. The efficacy of the operation was evaluated by counting platelets one day before surgery and on the first and fifth postoperative day. Data chosen for analysis included age, gender, weight, height, American Society of Anaesthesiologists (ASA) score, number of converted patients, estimated blood loss during operation, operating time, postoperative secretion through the drains, morbidity, mortality and postoperative hospital stay. RESULTS: There were no significant differences between LS and OS groups according patients age, weight, height, gender and ASA score. The mean operative time was 138.8 +/- 50.1 min in LS group and was significantly longer than operative time in OS group (102.3 +/- 21.3 min). One patient was converted to open splenectomy because of severe bleeding from splenic hilum. Postoperative complications occurred in one patient from each group. The mean intraoperative blood loss was 460 +/- 125 ml in LS group and 510 +/- 140 ml in OS group (p > 0.05). Postoperative secretion through the drains and postoperative secretion time in LS group was significantly lower and shorter than in OS group. Postoperative hospital stay in LS group (5 +/- 1.1 days) was significantly shorter than in OS group (8 +/- 1.4 days). After splenectomy, there was an immediate increase in the platelet count of all patients in both groups. Between the day before surgery and the first postoperative day, the mean platelet count rose significantly from 75 +/- 57.0 G/L to 117 +/- 84.2 G/L in LS group and from 64 +/- 60.1 G/L to 122 +/- 79.3 G/L in OS group. Between the first postoperative day and the fifth postoperative day, the mean platelet count also rose significantly in both groups: from 117 +/- 84.2 G/L to 259 +/- 151.0 G/L in LS group and from 122 +/- 79.3 G/L to 258 +/- 158.4 G/L in OS group. In the immediate postoperative period (five days after operation), all LS group and OS group patients responded to the splenectomy. CONCLUSIONS: Laparoscopic or open splenectomy are equally efficacious in patients with ITP, with an immediate response rate of 100 % in our study. Our study results show that open splenectomy appears superior to laparoscopic procedure in terms of shorter operative time. Laparoscopic splenectomy appears superior to open procedure in terms of postoperative hospital stay, postoperative drainage time, less postoperative secretion through the drains. These two approaches are similar with regard to blood loss during operations and the rate of postoperative complications.     

Laparoscopic versus open incisional hernia repair

BACKGROUND: To analyze hospital resource utilization for laparoscopic vs open incisional hernia repair including the postoperative period. METHODS: Prospectively collected administrative data for incisional hernia repairs were examined. A total of 884 incisional hernia repairs were examined for trends in type of approach over time. Starting October 2001, detailed records were available, and examined for operating room (OR) time, cost data, length of stay (LOS), and 30-day postoperative hospital encounters. RESULTS: Of the total, 469 incisional hernias were approached laparoscopically (53%) and 415 open (47%). Laparoscopic repair had shorter LOS (1 +/- 0.2 days vs 2 +/- 0.6 days), longer OR time (149 +/- 4 min vs 89 +/- 4 min), higher supply costs (2,237 dollars +/- 71 dollars vs 664 dollars +/- 113 dollars), slightly lower total hospital cost (6,396 dollars +/- 477 dollars vs 7,197 dollars +/- 1,819 dollars), and slightly more postoperative hospital encounters (15% vs 13%). Use of laparoscopy increased over time (37% in 2000 vs 68% in 2004). CONCLUSIONS: Laparoscopic incisional hernia repair is becoming increasingly popular, and not at increased cost to the health care system.     

Laparoscopic splenectomy and lymph node biopsy for hematologic disorders.

OBJECTIVE: The authors audit the introduction of laparoscopic splenectomy and laparoscopic intra-abdominal lymph node biopsy and compare outcomes with a parallel cohort of patients undergoing open splenectomy. SUMMARY BACKGROUND DATA: Laparoscopic splenectomy was first reported in 1992. It was introduced into clinical practice at the Royal Brisbane Hospital in 1991. Between June 1991 and March 1994, 24 patients have undergone laparoscopic splenectomies and 23 patients have had laparoscopic intra-abdominal lymph node biopsies. METHODS: Laparoscopic splenectomy was performed using a four- or five-port technique. The splenic hilum was secured using a linear stapler cutter, and the spleen was removed after placing it in a laparoscopic bag. Lymph node biopsy was performed using a three- or four-port technique, depending on the site and size of the lymphadenopathy. RESULTS: Laparoscopic splenectomy was completed in 22 patients (92%). Median hospital stay was 3 days (range 2-7 days) and morbidity occurred in two patients (8%). Lymph node biopsy was completed laparoscopically in 21 of 23 patients (91%), with morbidity in two cases (9%). Median hospital stay was 2 days (range 1-6 days), with a diagnostic accuracy of 90%. Comparison with open splenectomy revealed that the laparoscopic approach took significantly longer to perform (p = 0.0002), but resulted in a significantly shorter hospital stay (p = 0.0005). CONCLUSIONS: Both laparoscopic splenectomy and laparoscopic lymph node biopsy currently are used as the treatments of choice for hematologic disease in our institution.     

Trends in laparoscopic splenectomy for massive splenomegaly

HYPOTHESIS: During the past 10 years, expertise with minimally invasive techniques has grown, leading to an increase in successful laparoscopic splenectomy (LS) even in the setting of massive and supramassive spleens. DESIGN: Retrospective series of patients who underwent splenectomy from November 1, 1995, to August 31, 2005. SETTING: Academic tertiary care center. PATIENTS: Adult patients who underwent elective splenectomy as their primary procedure (n = 111). MAIN OUTCOME MEASURES: Demographics, spleen size and weight, conversion from LS to open splenectomy, postoperative length of stay, and perioperative complications and mortality. Massive splenomegaly was defined as the spleen having a craniocaudal length greater than 17 cm or weight more than 600 g, and supramassive splenomegaly was defined as the spleen having a craniocaudal length greater than 22 cm or weight more than 1600 g. RESULTS: Eighty-five (77%) of the 111 patients underwent LS. Of these 85 patients, 25 (29%) had massive or supramassive spleens. These accounted for 40% of LSs performed in 2004 and 50% in 2005. Despite this increase in giant spleens, the conversion rate for massive or supramassive spleens has declined from 33% prior to 1999 to 0% in 2004 and 2005. Since January 2004 at our institution, all of the massive or supramassive spleens have been removed with a laparoscopic approach. Patients with massive or supramassive spleens who underwent LS had no reoperations for bleeding or deaths and had a significantly shorter postoperative length of stay (mean postoperative length of stay, 3.8 days for patients who underwent LS vs 9.0 days for patients who underwent open splenectomy; P<.001). CONCLUSIONS: Despite conflicting reports regarding the safety of LS for massive splenomegaly, our data indicate that with increasing institutional experience, the laparoscopic approach is safe, shortens the length of stay, and improves mortality.     

Massive Splenomegaly in Children: Laparoscopic Versus Open Splenectomy

Background and Objectives:

Laparoscopic splenectomy for massive splenomegaly is still a controversial procedure as compared with open splenectomy. We aimed to compare the feasibility of laparoscopic splenectomy versus open splenectomy for massive splenomegaly from different surgical aspects in children.

Methods:

The data of children aged <12 years with massive splenomegaly who underwent splenectomy for hematologic disorders were retrospectively reviewed in 2 pediatric surgery centers from June 2004 until July 2012.

Results:

The study included 32 patients, 12 who underwent laparoscopic splenectomy versus 20 who underwent open splenectomy. The mean ages were 8.5 years and 8 years in the laparoscopic splenectomy group and open splenectomy group, respectively. The mean operative time was 180 minutes for laparoscopic splenectomy and 120 minutes for open splenectomy. The conversion rate was 8%. The mean amount of intraoperative blood loss was 60 mL in the laparoscopic splenectomy group versus 110 mL in the open splenectomy group. Postoperative atelectasis developed in 2 cases in the open splenectomy group (10%) and 1 case in the laparoscopic splenectomy group (8%). Oral feeding postoperatively resumed at a mean of 7.5 hours in the laparoscopic splenectomy group versus 30 hours in the open splenectomy group. The mean hospital stay was 36 hours in the laparoscopic splenectomy group versus 96 hours in the open splenectomy group. Postoperative pain was less in the laparoscopic splenectomy group.

Conclusion:

Laparoscopic splenectomy for massive splenomegaly in children is safe and feasible. Although the operative time was significantly greater in the laparoscopic splenectomy group, laparoscopic splenectomy was associated with statistically significantly less pain, less blood loss, better recovery, and shorter hospital stay. Laparoscopic splenectomy for pediatric hematologic disorders should be the gold-standard approach regardless of the size of the spleen.     

Laparoscopic splenic procedures in children: experience in 231 children

OBJECTIVES: The purpose of this report is to evaluate the efficacy of and complications observed after laparoscopic splenic procedures in children. METHODS: Review of a prospective database at a single institution (1995-2006) identified 231 children (129 boys; 102 girls; average age 7.69 years) undergoing laparoscopic splenic procedures. RESULTS: Two hundred twenty-three children underwent laparoscopic splenectomy (211 total; 12 partial) by the lateral approach. Indication for splenectomy was hereditary spherocytosis (111), immune thrombocytopenic purpura (36), sickle cell disease (SCD) (51), and other (25). Four (2%) required conversion to an open procedure. Eight additional laparoscopic splenic procedures were performed: splenic cystectomy for epithelial (4) or traumatic (2) cyst, and splenopexy for wandering spleen (2). Average length of stay was 1.5 days. Complications (11% overall, 22% in SCD patients) included ileus (5), bleeding (4), acute chest syndrome (5), pneumonia (2), portal vein thrombosis (1), priapism (1), hemolytic uremic syndrome (1), diaphragm perforation (2), colonic injury (1), missed accessory spleen (1), trocar site hernia (1), subsequent total splenectomy after an initial partial (1), and recurrent cyst (1). Subsequent operations were open in 3 (colon repair, hernia, and missed accessory spleen) and laparoscopic in 2 (completion splenectomy, and cyst excision). There were no deaths, wound infections, or instances of pancreatitis. CONCLUSIONS: Laparoscopic splenic procedures are safe and effective in children and are associated with low morbidity, higher complication rate in SCD, low conversion rate, zero mortality, and short length of stay. Laparoscopic splenectomy has become the procedure of choice for most children requiring a splenic procedure.     

Open versus laparoscopic splenectomy for idiopathic thrombocytopenic purpura: clinical and economic analysis

BACKGROUND: Since 1991, laparoscopic splenectomy (LS) has gained acceptance in the treatment of hematologic disorders, including idiopathic thrombocytopenic purpura (ITP). Several studies suggest that LS provides benefits over open splenectomy (OS). However, study design flaws hinder formal technology assessment. METHODS: We retrospectively reviewed medical and administrative records of patients who underwent splenectomy for ITP between January 1995 and December 2000 to compare clinical and economic outcomes associated with LS and OS. RESULTS: Eighty-six patients were identified; 42 underwent an attempted LS and 44 had OS. Preoperative patient characteristics were similar between groups. Mean operative and anesthesia times for LS and OS were 167 and 201 minutes and 119 and 151 minutes, respectively (P <.001). Overall transfusion and postoperative complication rates were similar between groups. On average, LS patients required 1.2 fewer days of parenteral analgesia and were able to tolerate a general diet 1.7 days earlier. Mean postoperative stay was 2 days lower for LS patients and mean total direct costs did not differ by surgical method (US dollars 8134 vs US dollars 8200). CONCLUSIONS: This observational study shows that LS is safe and offers advantages over OS: less postoperative pain, earlier general diet tolerance, and shorter hospital stay. These benefits are obtained at no significant additional cost.     

Laparoscopic adrenalectomy and splenectomy are safe and reduce hospital stay and charges

The proposed benefits of laparoscopy for certain surgical procedures have been decreased post-operative pain and hospital stay balanced against the proposed deficits of increased costs. We have reviewed our data to evaluate factors associated with patient, procedure, and hospital charges for patients undergoing open versus laparoscopic adrenalectomy and splenectomy during the same time period. Eighty-seven patients underwent adrenalectomy (n = 47) or splenectomy (n = 40) from October 30, 1995 to June 6, 2001 and were retrospectively reviewed. Patient and operative factors were analyzed by intent to treat; the major endpoints were operating room (OR) time in minutes, blood loss in cm3, length of hospital stay in days, and charges broken down by anesthesia/operation [OR/recovery room (RR)] and total charges in dollars x 1000. Comparisons of means were analyzed by unpaired t test; data are presented as mean +/- SEM, and significance is defined as P < 0.05. Median age of the group was 47 years (range 20-77). Forty-five patients underwent a laparoscopic approach of which two were converted to open (4%) as compared with 42 undergoing an open operation; one patient from each group was excluded from outcome analyses because of prolonged hospitalization (>3 weeks). Operative mortality of the whole group was one per cent. There were no differences between the groups with respect to age, gender, or comorbidity. The laparoscopic group had significantly longer operative times and OR/RR charges. However, the length of hospital stay and the total charges for the patient undergoing a laparoscopic approach were significantly less (P < 0.05). We conclude that a laparoscopic approach for adrenalectomy or splenectomy can be accomplished in approximately 95 per cent of patients selected for this procedure. Despite prolonged OR time and increased OR/RR charges the laparoscopic procedures resulted in significantly decreased length of hospital stay and overall patient charges. Laparoscopy is a safe and cost-effective approach and should be strongly considered in patients requiring adrenalectomy or splenectomy.     

Laparoscopic versus open splenectomy for massive splenomegaly: a comparative study

BACKGROUND: Despite the benefits of the laparoscopic approach to splenectomy, its application in patients with massive splenomegaly (splenic weight >or= 1000 g) remains controversial. In this study we evaluated the safety and feasibility of laparoscopic splenectomy for massive splenomegaly compared with open splenectomy. MATERIALS AND METHODS: One surgeon applied the laparoscopic approach to splenectomy to all comers with massive splenomegaly, while other surgeons carried out the surgery through a laparotomy. The outcomes of the two approaches were compared on an intention-to-treat basis. Results of continuous variables are shown as medians. RESULTS: Fifteen patients underwent laparoscopic splenectomy between 2000 and 2005, and 13 underwent open splenectomy between 1996 and 2003. The two groups were comparable for age, sex, American Society of Anesthesiologists score, and splenic weight (1.3 vs. 1.1 kg). There was one conversion (6.6%) to open surgery. Although laparoscopic splenectomy was associated with significantly longer operating time (175 vs. 90 minutes, P < 0.001), it carried lower postoperative morbidity and mortality (13.3 vs. 30.8% and 0 vs. 7.7%, respectively). Laparoscopic splenectomy was associated with significantly lower total dose (29 vs. 264 mg morphine-equivalent, P < 0.0001) and duration of opiate usage (1 vs. 4 days, P < 0.0001); duration of parenteral hydration (24 vs. 96 hours, P = 0.006) and more rapid resumption of oral diet (24 vs. 72 hours, P = 0.017); and a shorter postoperative hospital stay (3 vs. 10 days, P < 0.0001). CONCLUSIONS: The laparoscopic approach to splenectomy for massive splenomegaly is feasible and safe. Despite a longer operating time, the postoperative recovery following laparoscopic splenectomy is smoother, with lower morbidity and shorter postoperative hospital stay compared with open splenectomy.
