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.     

An 18-year review of open and laparoscopic splenectomy for idiopathic thrombocytopenic purpura

BACKGROUND: Laparoscopic splenectomy has become the preferred surgical procedure for the management of idiopathic thrombocytopenic purpura (ITP). However, there studies have directly compared the incidence of recurrent ITP secondary to missed accessory spleens in open versus laparoscopic splenectomy. METHODS: Open and laparoscopic splenectomies performed for ITP at 4 sites over 18 years were analyzed. The incidence of recurrent disease secondary to missed accessory spleens was compared between the open and laparoscopic splenectomy groups. RESULTS: A total of 105 splenectomies (54 open/51 laparoscopic) were performed. Accessory spleens were identified in 6 laparoscopic and 6 open cases (P = .57). Recurrent disease occurred in 27.6% of open and 14.6% of laparoscopic cases (P = .222). There were no cases of recurrent ITP secondary to a missed accessory spleen in either group. CONCLUSIONS: The incidence of missed accessory spleens causing recurrent disease is similar when splenectomy is performed either open or laparoscopically.     

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 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.     

Laparoscopic splenectomy for massive splenomegaly

BACKGROUND: Laparoscopic splenectomy (LS) is the preferred operative approach for diseases involving normal-sized spleens. Our experience with laparoscopic splenectomy in the setting of massive splenomegaly is presented. METHODS: A prospective review of patients undergoing LS for massive splenomegaly was conducted. Massive splenomegaly (MS) in adults was defined as a craniocaudal length >or=17 cm or a morcellated weight >or=600 g. In children, spleens measuring fourfold larger than normal for age were considered massive. RESULTS: Forty-nine patients with MS were treated with LS. The most common primary diagnoses were lymphoma and leukemia. Mean splenic length was 20 cm (15 to 27 cm), with weights ranging from 600 to 4,750 g. Twelve patients with supermassive splenomegaly (length >22 cm) required a hand-assisted laparoscopic approach. There were no conversions to open surgery. Mean operating time was 171 minutes (90 to 369). Mean blood loss was 114 cc (<30 to 600 cc). Average length of stay was 2.3 days (1 to 16). Minor postoperative complications occurred in 3 patients. CONCLUSIONS: Laparoscopic splenectomy in the setting of splenomegaly is safe and appears to minimize perioperative morbidity. In patients with supermassive splenomegaly, a hand-assisted laparoscopic approach may be required.     

Splenomegaly should not be considered a contraindication for laparoscopic splenectomy.

OBJECTIVE: To analyze the impact of spleen size on operative and immediate clinical outcome in a series of 74 laparoscopic splenectomies (LS). SUMMARY BACKGROUND DATA: LS is gaining acceptance as an alternative to open splenectomy. However, splenomegaly hinders LS, and massive splenomegaly has been considered a contraindication. METHODS: Between February 1993 and September 1997, 74 patients with a wide range of splenic disorders were treated by laparoscopy and prospectively recorded. They were classified into three groups according to spleen weight: group I, <400 g (n = 52); group II, 400 to 1000 g (n = 9); and group III, >1000 g (n = 13). Age, operative time, number of trocars required, need for perioperative transfusion, spleen weight, conversion rate, mode of spleen retrieval (bag or accessory incision), postoperative analgesia requirements, length of hospital stay, and morbidity rates were recorded. RESULTS: LS was completed in 69 patients, and the conversion rate was thus 6.7%. Operative time was significantly longer in patients with larger spleens, and an accessory incision was more frequently required. However, there were no significant differences in transfusion rate, length of stay, severe morbidity, or conversion rate. CONCLUSIONS: Preliminary evaluation of LS for patients with large spleens suggests that it requires a longer operative time, but it is feasible and may potentially offer the same advantages (shorter stay and faster recovery) as it does to those with smaller spleens.     

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 in children--a multicenter experience

Purpose

Splenectomy is frequently required in children for various hematologic pathologic findings. Because of progress in minimally invasive techniques, laparoscopic splenectomy (LS) has become feasible. The objective of this report is to present a multicenter experience of 159 laparoscopic splenectomies.

Methods

Records of 159 children, who underwent LS in 3 pediatric surgery centers between 1996 and 2006, were reviewed retrospectively with a special questionnaire. The indication for splenectomy were hematologic disorders (147), esophageal varices (6), splenic cyst (5), and tumor of the tail of the pancreas (1). The LS was performed using standard laparoscopic technique and instrumentation.

Results

There were 75 boys and 84 girls. Median age was 12.5 years (range, 2-19.4 years). Laparoscopic splenectomy alone was performed in 118 cases and LS with cholecystectomy or cholecystotomy in 36. In 5 cases, LS was performed together with fundoplication. Eight LS required conversion to an open procedure for following reasons: severe bleeding (3), massive splenomegaly (1), anatomical (2), and technical aspects (2). Accessory spleens were identified in 20 cases (12.6%). There was no mortality. Complications consisted of 8 conversions and postoperatively of mild generalized infection in 3 children and abdominal bleeding that resulted in re-laparoscopy in 1 case.

Conclusions

Laparoscopic splenectomy can be safely and effectively performed in children.

Massive splenomegaly is associated with significant morbidity after laparoscopic splenectomy

OBJECTIVE: To evaluate the impact of spleen weight on operative and clinical outcome in a series of 108 consecutive laparoscopic splenectomies. BACKGROUND: Laparoscopic splenectomy as an alternative to open splenectomy for splenomegaly is regarded as controversial. METHODS: Patients underwent laparoscopic splenectomy for a range of hematological disorders between November 1992 and February 2000. Multiple linear and logistic regression analysis were used to assess the effect of massive splenomegaly (>1000 g) on perioperative mortality and morbidity, after adjusting for the joint effects of patient age, weight, pre- and postoperative full blood counts, operating time, estimated blood loss, conversion rate, reoperation rate, and duration of hospital stay. RESULTS: Massive splenomegaly was recorded in 27 of 108 (25%) cases. In this group, splenic weight ranged from 1000 to 4750 g (median, 2500 g). Patients with splenic weight >1000 g had a significantly longer median operating time (170 vs. 102 minutes, P < 0.01), conversion rate (5/27 vs. 4/81, P < 0.05), postoperative morbidity (15/27 vs. 4/81, P < 0.01), and median postoperative stay (5 vs. 3 days, P < 0.01). Multivariate analysis found splenic weight to be the most powerful predictor of morbidity (P < 0.01). Patients with splenomegaly (>1000 g) were 14 times likely to have post operative complications. One patient died 3 days after surgery, following a pulmonary embolus (spleen weight 500 g, mortality 1/108, 0.9%). CONCLUSIONS: Laparoscopic splenectomy is feasible in patients with giant spleens. However, it is associated with greater morbidity, and the advantages of minimal access surgery in this subgroup of patients are not so clear.     

Laparoscopic splenectomy in children.

BACKGROUND: Laparoscopic splenectomy is being performed more commonly in children, although its advantages are not clear. We sought to determine whether laparoscopic splenectomy was superior to open splenectomy. METHODS: The records of all pediatric patients undergoing splenectomy without significant comorbidities over a 12-year period were examined. The patients were divided into those undergoing laparoscopic splenectomy and those undergoing open splenectomy. Demographics, operative time, estimated blood loss, spleen size, length of stay, and total charges were compared between the groups. RESULTS: Eighty-one (58%) children underwent laparoscopic splenectomy, and 59 (42%) children underwent open splenectomy. The groups were similar in age and sex; hereditary spherocytosis was more common in the LS group. Operating time was longer in the laparoscopic splenectomy group (231 +/- 10 min vs 138 +/- 9 min; P<0.001), but blood loss and complication rates were similar. Twelve (15%) conversions were necessary primarily due to spleen size. Although children undergoing LS had a shorter length of stay (2.4 +/- 0.1 vs 4.1 +/- 0.3 days; P<0.001), they incurred higher charges (dollars 21199 +/- 664 vs dollars 15723 +/- 1737; P<0.002). CONCLUSION: Laparoscopic splenectomy is a safe procedure in children, resulting in shorter hospital stay, which may translate into earlier return to activity and a smaller burden on the child's caretakers.     

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.     

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.     

Laparoscopic splenectomy: a personal series of 140 consecutive cases

Introduction

Laparoscopic splenectomy has emerged as a safe and effective treatment for a variety of haematological conditions. The objective was to review the results from a large personal series from the perspective of outcomes according to operative time, conversion to open operation, complications and mortality. The application of laparoscopic splenectomy to cases of splenomegaly without hand assistance is examined.

Patients and Methods

A retrospective review of 140 patients undergoing laparoscopic splenectomy at a single university hospital by one surgeon during 1994-2006. Case notes were reviewed and data collected on operative time, conversion to open procedure, morbidity and mortality. Particular reference was made towards the results of cases of splenomegaly.

Results

In total 140 laparoscopic splenectomies were performed with a complication rate of 15% and no mortality. The median operative time was 100 min and conversion to open procedure was necessary in 2.1%. Conversion for cases of splenomegaly was only 5.7%. The median hospital stay was 3 days.

Conclusions

Laparoscopic splenectomy is a safe procedure with acceptable morbidity. A laparoscopic approach for splenomegaly is feasible.     

Laparoscopic splenectomy for massive splenomegaly in benign hematological diseases

Background

Laparoscopic splenectomy has become the standard of care for benign hematological disease affecting the spleen; its role in massive splenomegaly remains controversial. In this study, we evaluated the outcome of laparoscopic splenectomies in terms of spleen size in a group of 83 patients of benign hematological diseases.

Methods

From July 2003 to December 2009, 83 patients underwent laparoscopic splenectomy for various benign hematological diseases. The data were recorded and analyzed in a retrospective manner. The patients were divided in to two groups according to the spleen weight; group I?<?2,000?g (n?=?54) and group II?>?2,000?g (n?=?29). Age, sex, hematological condition, operative time, estimated blood loss, conversion to open surgery, splenic weight, length of hospital stay, time to liquid diet, and morbidity were all recorded.

Results

Laparoscopic splenectomy was completed in 79 patients (95.2?%). Operative time (p?=?0.01) and estimated blood loss (p?=?0.001) was more in group II. The length of hospital stay (p?=?0.05) and the postoperative morbidity (p?=?0.001) also were significantly more in the second group. There was no mortality.

Conclusions

Laparoscopic splenectomy is possible and safe for massive splenomegaly in hematological disease (>2,000?g), but it needs longer operative time and hospital stay.     

Experience with laparoscopic splenectomy

BACKGROUND/PURPOSE: The laparoscopic splenectomy (LS) often is adopted to treat children affected by hematologic diseases. Many of the pitfalls of LS are related to the 2 steps-dissection and extraction. Although various methods have been adopted, the conversion rate still is too high during the learning curve period. The authors analyse their experience in 54 laparoscopic splenectomies performed by their teams in 3 European countries. METHODS: From 1995 to 1999, 54 children underwent laparoscopic splenectomy, 4 of whom also underwent a concomitant cholecystectomy. There were 29 girls and 25 boys with ages ranging between 4 and 19 years (median, 8.1 years). All patients underwent an elective laparoscopic splenectomy: Thirty children had hereditary spherocytosis, 13 had an idiopathic thrombocytopenic purpura, 10 were affected by a beta thalassemia, and 1 child had sickle cell disease. RESULTS: Mean operating time was 140 minutes (range, 100 to 250 minutes). Hospital stay ranged from 2 to 6 days (median, 3 days). In 7 patients the spleen was removed through a 7-cm minilaparotomy; in another 46 cases the spleen was captured into an extraction bag, fragmented, and then removed through the umbilical or left orifice. There was one conversion to open surgery because of a camera failure during the operation. CONCLUSIONS: On the basis of our experience we believe that the operating time of LS is still too long compared with open surgery, and the extraction phase still not simple enough. A perfect control of hemostasis is fundamental because severe complications can arise from even a slight bleeding episode. It also is very important to search for and remove any accessory spleens. In our series this occurred in 7 patients, one of whom had 3 accessory spleens. The laparoscopic approach is today a good alternative to open splenectomy.     

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.     

Laparoscopic splenectomy: a single center experience. Unusual cases and expanded inclusion criteria for laparoscopic approach

Laparoscopic splenectomy (LS) is nowadays considered as the gold standard for most hematological diseases where splenectomy is necessary, but many questions still remain. The aim of this study was to analyze our 5-years experiences consisting of 48 consecutive LS cases in order to assess the optimal approach and the feasibility of the procedure also in malignant diseases and unusual cases such as a primary spleen lymphoma, a big splenic artery aneurism, or a spleen infarct due to a huge pancreatic pseudo-cyst. Forty-eight consecutive patients underwent LS from January 2006 to January 2011 with at least 1-year follow-up. Clinical data and immediate outcome were retrospectively recorded; age, diagnosis, operation time, perioperative transfusion requirement, conversion rate, accessory incision, hospital stay, and complications were analyzed. We had 14 cases of malignant splenic disease, the most frequent malignant diagnosis was non-Hodgkin’s lymphoma (12/14, 85.7 %). Splenomegaly (interpole diameter (ID) >20 cm) was observed in 12 cases (25 %) and massive splenomegaly (ID >25 cm) in 3 cases (6.25 %). Conversion to laparotomy occurred in two patients (4.16 %), both associated to uncontrollable bleeding in patients with splenomegaly. Mean operative time was 138 ± 22 min. Mean hospital stay was 4.5 days. Postoperative morbidity rate was 8.8 % for the benign group and 35.7 % in the malignant group. Mortality occurred in 1/48 patients (2.08 %), as a result of overwhelming post-splenectomy infection (OPSI). LS can be performed safely for malignant splenic disease and splenomegaly without any statistically significant increase of morbidity and mortality rate. Conversion rate is increased for massive splenomegaly. LS should be considered as the preferential approach even in patients with malignant disease, splenomegaly, or unusual cases. Massive splenomegaly should be considered as relative contraindication to LS even at experienced centers.     

The ascendance of laparoscopic splenectomy

The application of laparoscopic techniques for abdominal procedures has been achieved with varying success. The general acceptance of laparoscopic splenectomy (LS) may be hindered by its infrequent performance and difficulty in manipulating the spleen. A retrospective review of splenectomies performed for primary splenic pathology was done to assess the role and outcome of LS. One hundred fifty LSs were performed from July 1995 through September 1999. Over that time period the proportion of LS performed increased steadily from 17 to 75 per cent of all splenectomies. The primary indications for splenectomy included immune thrombocytopenic purpura in 75 (50%), lymphoma/leukemia 36 (24%), and splenomegaly 19 (13%). There were 86 females and 64 males. Immediately before operation 36 patients (4%) had a platelet count <50,000/ mL, and 24 patients (16%) a hemoglobin <10 mg per cent. The mean operative time was 161 minutes with an average blood loss of 138 cm3 (<50-800). The mean morcellated weight of the entire group was 411 g (33-3300) indicating generally large splenic size. In the 37 patients with splenomegaly the mean weight was 735 g (293-3300). There were two conversions to open splenectomy. Two patients with hematologic malignancy, splenomegaly, and cytopenias died from overwhelming post-splenectomy sepsis (1.3%). Morbidity occurred in 14 (9%) with the most common complication being pancreatitis in seven (5%). The median length of postoperative stay was 2.4 days (range 1-5). In summary LS has rapidly replaced the open approach for nearly all elective splenectomies in adults and children. When performed with the patient in the lateral position it can be accomplished with minimal morbidity, even in complex patients, including those with splenomegaly.     

Does open surgery continue to have a role in elective splenectomy?

Background Since it was first reported in 1991, laparoscopic splenectomy has become the procedure of choice for elective splenectomy. However, doubts have been raised regarding the suitability of patients with splenomegaly (>1 kg) for laparoscopic resection because there have been reports of greater morbidity and higher conversion rates in this group of patients. Since 2000, patients referred to the authors’ center for splenectomy with an estimated spleen weight exceeding 1 kg have undergone splenectomy by the open approach. Methods Between September 1995 and April 2005, 95 elective splenectomies were performed by a single surgeon. Operative data were collected prospectively. Results A comparison between the operations that took place before 2001 (n = 47) and those performed after 2000 (n = 48) for all sizes of spleen showed significant reductions in conversion rate, operative time, and hospital stay in the later group. As compared with laparoscopic splenectomy (n = 11), open splenectomy (n = 18) for cases of splenomegaly resulted in a significantly shorter operative time, less operative blood loss, and no significant difference in hospital stay. Conclusion Although laparoscopic splenectomy is the treatment of choice for the majority of patients requiring elective splenectomy, the procedure for patients with significant splenomegaly requires caution and common sense. This study shows that an open splenectomy for these patients significantly reduces operative time and blood loss without increasing morbidity or hospital stay.
