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 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.     

Splenectomy for idiopathic thrombocytopenic purpura

Background: This study aimed to compare the safety, efficacy, and clinical benefits of laparoscopic splenectomy (LS) to open splenectomy (OS) in patients with idiopathic thrombocytopenic purpura (ITP). Methods: The results from 14 consecutive patients who underwent LS for ITP were reviewed and compared with the results from patients who underwent OS for the same disease. Demographics, concomitant disease on admission, and platelet counts were evaluated, as were details of the surgical procedure, postoperative physiologic status, and hospital stay. Results: Mean operative time was 88.3 min for OS and 146.4 min in LS group (p < 0.05). The conversion rate to open splenectomy was 7.1. Therapeutic response to splenectomy was 92.8% in the LS group and 86.6% in the OS group. Bowel canalization, return to liquid diet, and length of hospital stay were all significantly delayed in the OS group as compared with those who underwent LS (p= 0.01, p= 0.02, p= 0.005, respectively). In the OS group the morbidity rate was 13.3%, whereas in the LS group it was 7.1%. Conclusions: Laparoscopic splenectomy represents a valid alternative to conventional splenectomy in the treatment of ITP. Received: 10 October 1997/Accepted: 11 March 1998     

Use of laparoscopic splenectomy in developing countries: analysis of cost and strategies for reducing cost

BACKGROUND: In general, laparoscopic surgery is more expensive than open surgery. However, recent reports showed lower overall cost. PATIENT AND METHODS: Fourteen patients underwent laparoscopic splenectomy (LS) and 15 patients open splenectomy (OS). Patients were evaluated with regard to blood loss, complication rate, length of hospital stay, operative time, presence of accessory spleens, hospital cost, and total cost. For the OS group, there was no laparoscopic instrument cost, and the total cost was equal to the hospital cost. In the LS group, total cost was calculated by adding the hospital cost to the cost of laparoscopic instruments. RESULTS: The postoperative hospitalization was shorter in the LS group than the OS group (3.4 vs. 7.5 days), but the operating time was significantly longer for the LS group. The mean hospital cost was calculated as US $1,055 in the LS group and $1,664 in the OS group. The overall total cost was $1,664 for the OS group and $2,064 for the LS group. In the LS group, less morbidity and shorter postoperative hospital stay resulted in lower hospital cost. CONCLUSION: The cost for laparoscopic instruments is the main factor responsible for the high total cost of LS. Resterilization of disposable laparoscopic instruments is feasible and a more economic way of treatment compared with splenectomy with totally disposable laparoscopic instruments and has costs comparable to those of open surgery.     

Laparoscopic vs open splenectomy.

HYPOTHESIS: Laparoscopic splenectomy (LS) provides health benefits to patients compared with open splenectomy (OS) in terms of perioperative morbidity, complications, and patient recuperation. DESIGN: Prospective operative and outcome data of LS patients were compared with those of OS patients (historical controls). SETTING: Data were gathered, and patients were evaluated and treated at 2 McMaster University teaching hospitals in Hamilton, Ontario, and at the University of Kentucky Chandler Medical Center, Lexington, also a teaching hospital. PATIENTS: From January 1, 1994, through October 31, 1998, a total of 210 patients were studied. Of them, 147 patients from 3 university teaching hospitals underwent LS. These patients were matched with 63 OS patients according to age, sex, spleen weight, indication for splenectomy, and preoperative morbidity score. INTERVENTIONS: A total of 147 patients evaluated for elective splenectomy underwent LS. MAIN OUTCOME MEASURES: Spleen weight, operative time, intraoperative blood loss, postoperative hospital stay, perioperative complications, and cost. RESULTS: No significant difference in mean spleen weight was found between groups. Mean operative time was significantly longer for LS, but intraoperative blood loss was significantly lower. Mean postoperative hospital stay was significantly lower and perioperative complications significantly fewer for LS patients. Mean cost for LS with no complications was slightly lower than for OS. CONCLUSIONS: Compared with OS, the lateral approach to LS takes longer to perform but results in reduced blood loss, shorter postoperative stay, and fewer complications. Mean weighted cost of LS is lower than OS at the study institutions. A prospective, randomized, controlled trial comparing these techniques is planned.     

Laparoscopic splenectomy for ITP

Background: A comparison of safety, efficacy, and cost of laparoscopic splenectomy (LS) vs open splenectomy (OS) for idiopathic thrombocytopenic purpura (ITP) was performed. Methods: The records of 49 consecutive patients who underwent splenectomy for ITP (31 LS and 18 OS) at a large metropolitan teaching hospital between 3/91 and 8/95 were reviewed. Morbidity, mortality, hospital stay, operative time, blood loss, time to oral fluid intake, direct costs, and operating room (OR) costs were analyzed. Results: Age, sex, comorbidity, and spleen size were similar in both groups. LS was successful in 94% of patients in whom it was attempted. Operative times showed a learning curve for LS, with average times for the last ten cases (94 ± 35 min) significantly shorter than for the first ten (p= 0.01) and also shorter than for OS (103 ± 45 min). Postsurgical hospital stay was 2.9 ± 1.3 days for LS and 6.9 ± 3.0 days for OS (p < 0.001). Patients tolerated an oral diet 1.2 ± 0.5 days after LS and 3.2 + 0.7 days after OS (p < 0.001). Direct hospital cost was $5,509 ± 3,636 for LS and $9,031 ± 12,752 for OS. In the LS group, six patients (21%) had accessory spleens identified and removed, compared with two patients (11%) in the OS group. Platelet counts did not respond in two (7%) patients in the LS group, but no accessory spleens were identified by nuclear scan. One major complication occurred in the LS group. There were no cases of splenosis or mortality in either group. Conclusions: LS is a safe and effective treatment for ITP, with significantly shorter postoperative hospital stay than OS.

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 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     

Laparoscopic surgery of the spleen: state of the art

INTRODUCTION: Laparoscopic splenectomy (LS) offers superior visualization and access to the spleen and avoids the major laparotomy incision necessary in open splenectomy (OS). This review summarizes the current knowledge of laparoscopic techniques for splenectomy from the perspective of surgeons whose combined experience now totals 340 cases. BACKGROUND AND DISCUSSION: While LS has been applied across the spectrum of splenic diseases, it is most indicated in treatment of a benign hematologic condition with a normal or slightly enlarged spleen as seen in autoimmune thrombocytopenic purpura (ITP), autoimmune deficiency syndrome-related ITP, hemolytic anemia, or spherocytosis. Both anterior and lateral approaches have been used for LS. While benefits of the anterior approach include access to the splenic artery along the superior border of the pancreas within the lesser sac, thus securing vascular control early in the procedure, the lateral approach allows for improved exposure of and access to the splenic pedicle. Also, mechanics and sequence of dissection are enhanced and more intuitive to the surgeon using the lateral approach, and the tail of the pancreas is more easily identified. Potential perioperative complications of LS include hemorrhage, injury to the tail of the pancreas, and deep vein thrombosis. The most common criticisms facing LS are the potential for missed accessory spleens, longer operating time, and greater operating room costs compared to OS. However, while LS requires a longer operating time than OS, studies indicate shorter postoperative hospital stays for LS versus OS patients in comparable cases, which can, in turn, reduce the total hospital cost for the procedure. CONCLUSION: Although LS continues to pose certain technical challenges--such as management of the massive spleen, specimen extraction, and identification of remotely located accessory spleens--its advantages over OS in terms of faster postoperative recovery, shorter hospital stay, and equivalent or lower perioperative morbidity are now well established. Indications for LS and more laparoscopic spleen-conserving surgery are likely to broaden.     

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 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 versus open splenectomy: a comparative study

Laparoscopic splenectomy (LS) is gaining wide acceptance as a safe, effective alternative to open splenectomy (OS) in the treatment of hematologic disorders in adult and pediatric patients, with low conversion rates and complications. The aim of this retrospective case-control study was to compare two cohorts of patients, with similar characteristics, who underwent OS or LS in a single institution. The medical records of the initial 20 consecutive patients who underwent LS were reviewed and compared with a control group of 28 patients undergoing OS, matched for age, gender, diagnosis, splenic size and weight, and American Society of Anesthesiologists score. Data were collected regarding operative time, blood loss, blood transfusions, pathologic findings, accessory spleen detection, complications, ileus duration, and postoperative hospital stay. Nineteen patients underwent attempted LS. One procedure (5%) was converted to OS for uncontrolled hilar bleeding. Accessory spleens were detected in two cases in the LS group compared with four cases in the OS group (14%). Mean operative time was 165 minutes (range: 100-240 minutes) for LS and 114 minutes (75-180 minutes) for OS (P < 0.001). In the LS group a regular diet was tolerated 36 hours (range: 24-48 hours) after surgery compared with 72 hours (range: 48-96 hours) for the OS group (P < 0.001), and mean postoperative hospital stay was 4.1 days (range: 3-8 days) for LS, compared with 8.1 days (range: 5-12 days) for OS (P < 0.001). No differences were observed in blood loss, complication rates, or transfusion requirements. Compared with OS, LS requires more operative time (showing a learning curve), is comparable in blood loss, transfusion requirements, complication rates, and detection of accessory spleens and appears to be superior in terms of return of bowel function and hospital stay.     

Hematological long-term results of laparoscopic splenectomy for patients with idiopathic thrombocytopenic purpura: a case control study

Background Laparoscopic splenectomy (LS) for idiopathic thrombocytopenic purpura (ITP) appears, when compared to open splenectomy (OS), associated with immediate important advantages. However, in a number of patients splenectomy does not lead to an adequate response, or after initial adequate response a relapse occurs after some time. A relapse may be associated to the presence of accessory spleens and splenosis. The purpose of this study was to compare the operative outcome and the hematological results on the long term of a series of LS with a historic series of OS for the treatment of ITP.Methods A retrospective review was done of 50 consecutive patients who underwent LS for ITP. Patient characteristics, outcome of surgery, and hematological results were compared to a historical group of patients who underwent conventional splenectomy for ITP (n = 31). Response to splenectomy was defined in three groups: complete remission, partial remission, and no response. Grouping was based on hematological data.Results Concerning operative outcome and postoperative complications, there was a significant difference in favor of LS. Moreover, the hematological outcome of both groups showed no differences after a median period of 66 months (OS) and 35 months (LS), respectively.Conclusions Hematological results after laparoscopic splenectomy for ITP are comparable to those after open splenectomy in both the short and the long term.     

Are the favorable outcomes of splenectomy predictable inpatients with idiopathic thrombocytopenic purpura (ITP)?

BACKGROUND: Historically, splenectomy has been an accepted procedure in the management of immune thrombocytopenic purpura (ITP). However, it is also true that the response to splenectomy in patients with ITP seems to be unpredictable. Therefore, the purpose of this study was to identify clinical variables that might predict a favorable response to splenectomy in patients with ITP. METHODS: Data were collected retrospectively for 40 adult patients with ITP who underwent laparoscopic (LS) and open (OS) splenectomy at Emory University Hospital between 1992 and 1999. Demographics and outcomes were recorded. Age, sex, disease duration, comorbidities (ASA > 2), previous response to steroids and/or other medications, and preoperative platelet count were analyzed by univariate (t-test, Fisher's exact test) and multivariate statistical methods. RESULTS: Of the 20 patients in each group, improved platelet counts were noted in 18 patients (90%) in the LS group and 20 patients (100%) in the OS group. Follow-up (16 +/- 3 months) was obtained in 19 LS patients (95%) and 16 OS patients (80%), with 84% and 87.5% sustained response rates, respectively. After univariate analysis, two variables (age and disease duration) were found to be significantly related to the outcome of splenectomy (p 相似文献

Results of laparoscopic splenectomy for immune thrombocytopenic purpura

BACKGROUND: Laparoscopic splenectomy has been demonstrated to be technically feasible and safe for the treatment of immune thrombocytopenic purpura (ITP), hereditary spherocytosis, and Hodgkin's disease. PATIENTS AND METHODS: The study comprised 76 consecutive patients with chronic ITP who were admitted to our hospital from 1968 to 1997 and underwent splenectomy; 35 patients underwent a laparoscopic splenectomy, and 41 had open surgery. RESULTS: Laparoscopic splenectomy involved minimal incision, and a significantly lower frequency of analgesia was required for postoperative abdominal pain (1.4 versus 3.3); postoperative hospital stay was shorter (9.6 versus 20.1 days, P <0.05). Operative time was significantly longer for the laparoscopic surgery (204.5 versus 99.8 minutes, P <0.01), but blood loss was less (154.4 versus 511.7 g, P <0.01). During the present study (range 3.8 to 80 months), accumulative nonrecurrence rate was 67.9% in 5 years after surgery, which is similar to that of the previous open splenectomy. CONCLUSIONS: Laparoscopic splenectomy can become an alternative therapeutic modality in the treatment of ITP.

Laparoscopy Splenectomy for Massive Splenomegaly

ABSTRACT

Objective: This study is aimed to evaluate the feasibility of laparoscopic splenectomy (LS) for massive splenomegaly in patients with hypersplenism secondary to portal hypertension and liver cirrhosis. Method: A retrospective study of adult patients was conducted for splenectomy occurring from January 2006 to December 2010. We have performed the surgical procedures of splenectomy in 80 patients who were suffering from splenomegaly or hypersplenism secondary to portal hypertension and liver cirrhosis, among whom 40 patients underwent LS and another 40 patients received open surgery (OS). Results: Among the patients who had undergone LS, 2 patients were converted to OS and the other 38 patients underwent complete LS. The operation time, intraoperative blood loss, and the length of stay in LS group and OS group were 100–200 min (mean: 150 ± 30 min) vs. 120–210 min (mean: 100 ± 30 min), 50–1,000 ml (mean: 150 ± 110 ml) vs. 60–900 ml (mean: 140 ± 50 ml) and 4–9 days (mean: 6.1 ± 2.2 days) vs. 8–14 days (mean: 11.3 ± 2.3 days), respectively. No deaths occurred in the two groups, and there are no significant differences between the two groups in terms of estimated blood loss, complications, length of stay, and operating time. Conclusion: LS for treatment of massive splenomegaly is a feasible, effective, and safe surgical technique. Hypersplenism secondary to portal hypertension and liver cirrhosis are not supposed to be considered absolute contraindications to LS.     

Long-Term Outcomes of Laparoscopic Splenectomy Versus Open Splenectomy for Idiopathic Thrombocytopenic Purpura

The long-term outcomes of laparoscopic splenectomy (LS) versus open splenectomy (OS) in patients with idiopathic thrombocytopenic purpura (ITP) are not known. A retrospective analysis of 73 patients who underwent splenectomy (32 LS and 41 OS) for refractory ITP between April 2003 and June 2012 was conducted. LS was associated with shorter hospital stay (P = 0.01), less blood loss and blood transfusion during surgery, quicker resumption of oral diet (P < 0.0001), and earlier drain removal (P < 0.01). Conversion to OS was required in 4 patients (12.5%). Operation time was significantly longer in LS (P < 0.0001). Deep venous thrombosis (DVT) was observed in 1 patient after LS and in 4 patients after OS (P = 0.52). One patient died from intraperitoneal bleeding after OS, another patient developed pulmonary embolism. Median follow-up of 36 months was performed in LS group (29 of 32, 91%) and of 46 months in OS group (35 of 41, 85%), 25 patients (86%) in LS group and 32 (91%) in OS group reached sustained complete response (P = 0.792). Kaplan-Meier analysis showed that there was no significant difference in the relapse-free survival rate between the groups (P = 0.777). In conclusion, the long-term outcome of laparoscopic splenectomy is not different from that of open splenectomy for patients with ITP.Key words: Idiopathic thrombocytopenic purpura, Splenectomy, Laparoscopy, Postsplenic complications, Relapse-free survival rateIdiopathic thrombocytopenic purpura (ITP) is related to increased platelet destruction along with reduced platelet production via the specific autoantibodies and may cause a potentially life-threatening hemorrhage. Most ITP can be managed medically, yet some patients are refractory to medical agents such as prednisone, or anti-D globulin therapy,¹ and require splenectomy. Splenectomy can be performed as open splenectomy (OS) or laparoscopic splenectomy (LS).^1,2In the past decade, LS has rapidly become recognized as the gold standard for the management of nontraumatic splenic disorders, such as ITP, thrombotic thrombocytopenic purpura, and hemolytic anemia purpuras.^1–3 Systematic review studies have demonstrated a complete response or durable remission following splenectomy in 66% of adult patients with ITP.⁴ Several retrospective studies have compared the outcomes of OS and LS^1,5–7 and have shown comparable perioperative results, and the recent guidelines of the American Society of Hematology for ITP suggested that a similar efficacy is achieved with both LS and OS, the long-term efficacy of LS for this disorder is uncertain. Therefore, we have retrospectively studied 32 consecutive LS (LS group) and compared them with a historical control group of 41 consecutive OS (OS group) performed for ITP in order to compare the outcomes of LS with OS for ITP.
