Laparoscopic splenectomy

Laparoscopic spleen-preserving dome resection for a giant primary epithelial splenic cyst

Non-parasitic splenic cysts are rare and are seldom diagnosed outside the paediatric surgical practice. Giant true primary epithelial cysts greater than 14 cm in diameter are even rarer. Laparoscopic surgery is preferable; however, bleeding, splenectomy and recurrence are recognised risks. Here, we report a young female patient with a 21 cm symptomatic primary splenic cyst. The patient underwent a spleen-preserving laparoscopy and was followed up for 2 years when she had an MRI of the abdomen. Surgical, technical and perioperative treatment aspects are discussed here, in the context of the current literature.

Laparoscopic splenectomy in patients of β thalassemia: Our experience

BACKGROUND:

Laparoscopic splenectomy has become a standard treatment of various haematological disorders, but its feasibility in the setting of β thalassemia has not been established.

MATERIALS AND METHODS:

Fifty patients of β thalassemia underwent laparoscopic splenectomy between January 2006 and December 2008. “Anterior approach” method was practiced in all cases, with early ligation of splenic artery and delayed ligation of splenic vein. Specimen was extracted piecemeal via the umbilical port in initial 12 cases, while in 37 cases the specimen was extracted through a 7-8-cm pfannenstiel incision. Twelve patients of β thalassemia having grade IV splenomegaly with hepatomegaly were electively operated by conventional open method.

RESULTS:

The procedure was completed in 49 patients. One (2%) patient required conversion to open surgery. Mean operating time in the first 12 cases was 151 minutes (110-210 minutes), while in 37 cases of splenectomy completed laparoscopically it was 124 minutes (80-190 minutes) [P < 0.05]. Mean intra-operative blood loss was 73.8 ml (30–520 ml). No major intra-operative complications occurred. No patient required per-operative blood transfusion. Mean postoperative hospital stay was 4.7 days (2-11 days). Mean preoperative blood transfusion requirement was 11.98 units per patient per year, while mean postoperative blood transfusion requirement was 4.04 units [P< 0.05].

CONCLUSION:

Laparoscopic splenectomy is feasible and safe even in patients of β thalassemia with massive splenomegaly. Removal of specimen via a pfannenstiel incision significantly saves time, carries low morbidity and is a cosmetically acceptable alternative.

Laparoscopic versus open splenectomy in patients with beta thalassemia major

BACKGROUND

Laparoscopic splenectomy is considered the standard of care for the removal of the spleen in benign diseases. There are not sufficient data for the routine application of this technique in patients with beta thalassemia major.

MATERIALS AND METHODS

Twenty-eight consecutive beta thalassemia major patients who underwent elective splenectomy were randomized for open and laparoscopic splenectomy. Patient demographics, operative time, intraoperative and postoperative complications, conversion rate, transfusions, and length of stay were recorded.

RESULTS

There was no mortality in this series. There was no difference in complication rates between the two groups. Operative time was markedly increased in the group treated laparoscopically, as was the need for blood transfusions. Median hospital stay was decreased in the laparoscopic group (5 days) compared to the open group (6.5 days).

CONCLUSIONS

Laparoscopic splenectomy in patients with beta thalassemia major is feasible; however, it is more time consuming and bleeding occurs more often.

Laparoscopic splenectomy for hematologic diseases: a preliminary analysis performed on the Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS)

BACKGROUND

The Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS) was developed to provide at the national level an informative tool useful for performing multicenter studies in the field of spleen laparoscopic surgery. In this first study analyzing the IRLSS data, a cohort of patients with hematologic diseases was retrospectively investigated for potential predictive parameters that could affect the outcome of laparoscopic splenectomy.

METHODS

A total of 309 patients who underwent laparoscopic splenectomy for hematologic diseases in 17 Italian centers (between February 1, 1993, and September 30, 2004) were entered in the IRLSS. Their records were analyzed retrospectively by the Student's t-test, chi-square, and logistic regression.

RESULTS

The mean operative time was 141 min (range, 30-420 min). Conversion was necessary in 21 cases (7%), and approximately 1 accessory spleen in 25 patients (9%) was found. The mean spleen weight was 1191 g (range, 85-4,500 g). Perioperative death occurred in two cases (0.6%). No complications were experienced by 253 patients (81.9%), who had a mean hospital stay of 5.4 days (range, 2-30 days). Overall morbidity occurred in 56 patients (18.1%), mainly associated with transient fever (n = 22), pleural effusion (n = 13), and actual or suspected hemorrhage (n = 12), requiring a reintervention for 7 patients. Multivariate analysis found that body mass index (p = 0.024) and clinical indication (p = 0.004) were independent predictors for surgical conversion. The clinical indication was almost significant as an independent predictor for the occurrence of postoperative complication (p = 0.05).

CONCLUSIONS

This first study analyzing the IRLSS data shows that laparoscopic splenectomy may represent the gold standard treatment for hematologic diseases with normal-size spleen. The low morbidity and mortality rate suggests that laparoscopic splenectomy can be successfully proposed also for splenomegaly in hematologic malignancies.

Laparoscopic versus open splenectomy in the management of hematologic diseases

Splenectomy is the best available treatment for severe forms of hereditary spherocytosis, idiopathic thrombocytopenic purpura, and other hematologic conditions when these prove refractory to conservative management. It has been employed for many decades with low mortality and favorable remission rates. The use of laparoscopic splenectomy in recent years has been rapidly and even enthusiastically adopted in this field. However, the exact role of laparoscopic versus open surgery for hematologic diseases is still debated. In this study of 58 adult patients, laparoscopic procedures were compared with conventional splenectomies for similar indications. METHODS: All patients were operated on within an 8-year period. Subjects underwent similar procedures under the supervision of the same surgical school and were compared regarding age, gender, body mass index, and diagnosis. Laparoscopically managed cases (Group I, n = 30) were prospectively followed according to a written protocol, whereas the same investigation was retrospectively done with regard to traditional laparotomy (Group II, n = 28). Methods included general and demographic findings, duration and technical steps of operation, blood loss, weight of spleen, need for conversion (in minimally invasive subjects), intraoperative and postoperative complications, time until realimentation, postoperative hospitalization, mortality, and late follow-up including recurrence rate. RESULTS: Idiopathic thrombocytopenic purpura was the surgical indication in over 50% of the patients in both groups, but familial spherocytosis, thalassemia, myelodysplasia, and lymphomas were also represented in this series. Laparoscopic procedures took more time to perform (P = 0.004), and postoperative hospitalization was 2 days shorter, but this difference was not statistically significant. Postoperative hematocrit and volume of blood transfusions was equivalent, although the laparoscopic cases had a somewhat lower preoperative hematocrit (NS) and displayed better recovery for this measurement (P = 0.03). More patients in Group I were able to accept oral food on the first day than subjects undergoing conventional operations (P < 0.05). Relatively few conversions were necessary during the minimally invasive surgeries (13.3%), and postoperative early and late complications as well as recurrences occurred in similar proportions. Also, the mean weight of the spleen was not statistically different between the groups, although there was a marked numerical tendency toward larger masses in conventional procedures. No spleen in Group I exceeded 2.0 kg, whereas in Group II values up to 4.0 kg occurred, and the mean weight was 50% higher in the latter group. CONCLUSIONS: 1) Minimally invasive splenectomy was essentially comparable to open surgery with regard to safety, efficacy, and late results; 2) Advantages concerning shorter postoperative hospitalization could not be shown, despite earlier food intake and a non-significant tendency toward earlier discharge; 3) This new modality should be considered an option in cases of hematologic conditions whenever the spleen is not hugely enlarged.

Hand-assisted laparoscopic splenectomy in patients with splenomegaly or prior upper abdominal operation

BACKGROUND

Laparoscopic splenectomy (LS) in patients with significant splenomegaly or prior upper abdominal operation is technically challenging with a high conversion rate to open operation. We hypothesized that hand-assisted laparoscopic splenectomy (HLS) in this setting would improve operative (OR) outcomes without impacting post-OR ileus, length of stay, morbidity, or mortality, compared with LS.

METHODS

All patients with splenomegaly (spleen weight > or = 500 g) or prior upper abdominal operation undergoing LS or HLS between March 1996 and June 2001 were reviewed. Nonparametric continuous variables were expressed as median and intraquartile range with statistical significance determined by Wilcoxon rank sum test.

RESULTS

Of 41 patients reviewed, 22 underwent HLS, whereas 19 underwent LS. Median OR time for HLS was significantly less than for LS (161 minutes vs 212 minutes, P =.004). HLS was associated with a lower conversion rate (13.6% vs 36.8%, P =.08) and blood loss (325 mL vs 550 mL, P =.18) than LS, which approached statistical significance. HLS did not increase post-OR ileus, length of stay, morbidity, or mortality.

CONCLUSIONS

HLS in patients with significant splenomegaly or prior upper abdominal operation significantly shortens OR time compared with LS without adversely impacting post-OR ileus, length of stay, morbidity, or mortality. In addition, HLS may be associated with a lower conversion rate and decreased blood loss.

Laparoscopic marsupialization and hemisplenectomy for splenic cysts

BACKGROUND

Splenic cysts are a rare clinical entity in the United States, and historically, management has consisted of either partial or total splenectomy via an open approach. Laparoscopic treatment of splenic cysts with preservation of splenic parenchyma offers several advantages. Compared with the open approach, a laparoscopic approach may result in less postoperative pain and a more rapid return to full activity. Compared with total splenectomy, splenic preservation eliminates the risk of overwhelming postsplenectomy infection.

PATIENTS AND METHODS

We present two patients with splenic cysts. One patient was treated with laparoscopic marsupialization of the cyst and the other with laparoscopic hemisplenectomy.

RESULTS

Both patients are without further symptoms at 26 and 5 months' follow-up, respectively.

CONCLUSIONS

Laparoscopic marsupialization and hemisplenectomy are appropriate treatment options for patients with splenic cysts.

Laparoscopic splenectomy in chronic idiopathic thrombocytopenic purpura

Splenectomy remains the definitive treatment for idiopathic thrombocytopenic purpura (ITP). Issues related to timing of splenectomy, perioperative management of platelet count, deep vein thrombosis prophylaxis, and preoperative vaccination are not standardized. Predicting the outcome of splenectomy is desirable but, again, consistent evidence for a particular approach is lacking. Laparoscopic splenectomy, first introduced in 1991, has removed some of the barriers to acceptance of splenectomy and may well change its place in the various treatment algorithms. This article reviews current knowledge with respect to laparoscopic splenectomy and provides an analysis of current evidence regarding issues of safety, efficacy, and cost effectiveness. Surgical technique is briefly reviewed. The information is drawn from a comprehensive analysis of the literature, as well as my own large experience with laparoscopic splenectomy, the majority of which has been focused on laparoscopic splenectomy for ITP.

Laparoscopic splenectomy: single-centre experience of a district general hospital

We report the results of 20 consecutive laparoscopic splenectomies performed on haematology patients for a number of indications. Our series includes patients up to 77 years of age at the time of surgery and removal of spleens weighing up to 3530 g. The most significant benefit is the early rate of discharge post-operatively (median 2 d); however, there is a risk of conversion to open laparotomy (in this series 3/20, 15%). We show that laparoscopic splenectomy can be offered as a therapeutic option to patients unfit for conventional laparotomy and that even large and bulky spleens can be removed safely using this approach.

A learning curve for laparoscopic splenectomy at an academic institution

BACKGROUND

Laparoscopic splenectomy is emerging as the standard for treatment of benign splenic disorders. Since splenectomy is indicated relatively infrequently, issues arise concerning training of surgeons to perform laparoscopic splenectomy. Our experience with 50 laparoscopic splenic procedures is reported with emphasis on the learning curve at an academic institution.

MATERIALS AND METHODS

Data were prospectively collected on 50 consecutive patients undergoing attempted or successful laparoscopic surgical procedures on the spleen at Northwestern Memorial Hospital or The Chicago Health Care System, Lakeside Division, from April 1993 to April 1998, and on 5 patients undergoing open splenectomy from April 1993 to October 1995. Outcomes including conversion rate, operative time, day feedings were tolerated, and length of hospital stay was examined and correlated with the number of attempted cases.

RESULTS

Laparoscopic splenectomy progressed from an operation requiring two advanced laparoscopic surgeons to one performed by carefully supervised senior residents. Success rates increased from 60% initially to greater than 95% recently. Likewise, operative time decreased significantly from 195 to 97 min, while length of stay declined from 2.5 to 1.5 days. High success rates, low operative times, and short length of stays were achieved during the last 20 patients while surgical residents were taught to perform the procedures. The reasons for improvement are multifactorial including use of the harmonic scalpel, a change to the lateral position, and increasing experience with the procedure.

CONCLUSIONS

Laparoscopic splenectomy is a safe and effective procedure that reduces postoperative length of hospital stay. It can be performed successfully in most patients with operative times comparable to those of open splenectomy. Moreover, the procedure can (and should) be taught to residents once they master basic and advanced laparoscopic skills.

Laparoscopic versus open splenectomy in the management of splenomegaly: our preliminary experience

BACKGROUND

Laparoscopic splenectomy for normal-sized spleens has several advantages compared with laparotomy. Only a few cases of splenomegaly done by laparoscopy are reported in the literature. The purpose of this study is to show that laparoscopy for splenomegaly is feasible and has several advantages over the open operation.

METHODS

We performed retrospective chart review of 8 cases of splenomegaly managed by laparoscopy (group 1), 15 cases of open splenomegaly (group 2), and 27 cases of laparoscopic splenectomy for normal-sized spleens (group 3). Comparison has been done between groups 1 and 2 and groups 1 and 3 in terms of operative time, intraoperative estimated blood loss, need for blood transfusion, postoperative ileus, postoperative stay, and mortality and morbidity rates.

RESULTS

Patients in group 1 required longer operative time and significantly less intraoperative blood transfusion compared with group 2. The postoperative course was less complicated and shorter in group 1 than in group 2. Operative time was longer in group 1 compared with group 3. No significant differences in terms of postoperative course have been found between groups 1 and 3.

CONCLUSIONS

Laparoscopy for splenomegaly is a feasible, effective, and safe technique for experienced laparoscopic surgeons. This approach seems to have several advantages over the open operation. Prospective, randomized trials would be required for a proper quantitative evaluation.
