Splenectomy influences bone marrow infiltration in patients with splenic marginal zone cell lymphoma with or without villous lymphocytes.

BACKGROUND: Splenic marginal zone cell lymphoma (SMZL) is a low grade B-cell lymphoma in which patients can have circulating villous lymphocytes and can show a peculiar intrasinusoidal bone marrow (BM) infiltration. Splenectomy is the reported treatment of choice for these patients. The objective of this study was to evaluate the effects of splenectomy on patients with BM lymphomatous infiltration. METHODS: BM biopsies of 16 patients with SMZL were studied morphologically and immunohistochemically. In 12 patients, BM biopsies were taken before and after splenectomy. Four patients did not undergo splenectomy, and their BM biopsies were performed with an approximately 1 year interval. RESULTS: BM infiltration ranged from 10% to 40% of overall cellularity and was mostly of the intrasinusoidal type. After splenectomy, BM infiltration tended to become frankly nodular and showed an increase in tumor burden. Nonsplenectomized patients showed an unmodified picture. CONCLUSIONS: Splenectomy seems to induce important changes in patients with BM infiltration, probably through the lack of microenvironmental factors on circulating cells. These effects suggest reconsidering the role of splenectomy in the treatment of patients with SMZL.

Splenectomy versus conservative management for acute sequestration crises in people with sickle cell disease.

BACKGROUND: Acute splenic sequestration crises are a complication of sickle cell disease, with high mortality rates and frequent recurrence in survivors of first attacks. Splenectomy and blood transfusion, with their consequences, are the mainstay of long term management used in different parts of the world. OBJECTIVES: To assess whether splenectomy (total or partial) to prevent acute splenic sequestration crises in people with sickle cell disease improved survival and decreased morbidity in patients with sickle cell disease, as compared with regular blood transfusion. SEARCH STRATEGY: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group specialist trials register which comprises references identified from comprehensive electronic database searches, hand searching relevant journals and hand searching abstract books of conference proceedings Additional randomized controlled trials were sought from the reference lists of the studies found and reviews identified by the search strategy. Date of the most recent search: December 2001 SELECTION CRITERIA: All randomized or quasi-randomized controlled trials comparing splenectomy (total or partial) to prevent recurrence of acute splenic sequestration crises to no treatment or blood transfusion in people with sickle cell disease. DATA COLLECTION AND ANALYSIS: No trials of splenectomy for acute splenic sequestration were found. MAIN RESULTS: No trials of splenectomy for acute splenic sequestration were found. REVIEWER'S CONCLUSIONS: Splenectomy, if full, will prevent further sequestration and if partial, may reduce the recurrence of acute splenic sequestration crises but there is lack of evidence from trials that it improves survival and decreases morbidity in sickle cell disease. There is a need for a well-designed, adequately powered randomised controlled trial to assess the benefits and risks of splenectomy compared to transfusion programmes as a means of improving survival and decreasing mortality from ASS in people with sickle cell disease.

Long term follow-up after splenectomy performed for immune thrombocytopenic purpura (ITP).

Splenectomy is the only treatment of ITP known to have "curative" effects in a substantial fraction of patients. However, the true long-term outcome is uncertain and controversial because published series have not adjusted for the duration of follow-up. This IRB-approved retrospective study included all patients with ITP who underwent splenectomy between 1988-1993 at three major medical centers and required a minimum postoperative 5-year follow-up. Complete response (CR) was defined as all postsplenectomy platelet counts >150 x 10(9)/L without treatment; partial response (PR) as platelet counts > or =50 x 10(9)/L without treatment; and failure as platelet counts <50 x 10(9)/L or receiving therapy after splenectomy. Seventy-five patients identified with ITP underwent splenectomy from 1988 to 1993. Three patients died prior to 5-year follow-up, and 56 of the 72 patients (78%) were evaluable with follow-up for five years or longer, median 7.5 years. The immediate postoperative complete remission rate was 77%; 57% of patients have remained in prolonged CR. Thirty-seven patients (66%) have not required any therapy after splenectomy. Eight patients had platelet counts >150 x 10(9)/L for 4-8.5 years before relapsing; no clear plateau was attained in the remission curve. There was no operative mortality. Ten patients (18%) reported minor postoperative bleeding episodes. No life-threatening infections, significant heart disease, or pulmonary hypertension developed after splenectomy in the 434 patient-years of follow-up. This study helps to define the long-term results of splenectomy for ITP.

Do the acute platelet responses of patients with immune thrombocytopenic purpura (ITP) to IV anti-D and to IV gammaglobulin predict response to subsequent splenectomy?

The acute platelet response to Intravenous Gammaglobulin (IVIG) has been reported to predict response to subsequent splenectomy of patients with ITP. The current study was undertaken to determine if the platelet response to IV anti-D (Winrho-SDF) predicts response to subsequent splenectomy. The 61 HIV-uninfected children and adults in this study had taken part in the pre-licensing studies of IV anti-D and were all those who not only had evaluable platelet responses to IV anti-D but also had undergone splenectomy and had information available describing its 1-year outcome. Results of treatment with IVIG were available in 38 of these 61 patients. Neither response to the initial infusion of IV anti-D, nor response to the initial or last IVIG, predicted the response in either children or adults to subsequent splenectomy. However, response to the last anti-D infusion in adults was strongly correlated (P = 0.003) to response to subsequent splenectomy as was hemolysis >/=2.0 gm/dl after IV anti-D (P = 0.03). There was no overall relationship between response to IV anti-D or IVIG, and response to subsequent splenectomy. However, a good platelet response in adults to the last IV anti-D and a hemoglobin decrease >/=2.0 gm/dl both appeared to predict response to subsequent splenectomy.

Splenectomy vs. alpha interferon: a randomized study in patients with previously untreated hairy cell leukemia.

Twenty patients with previously untreated hairy cell leukemia were randomized to undergo either splenectomy or to receive interferon alfa-N1, a highly purified natural alpha interferon, as primary therapy. A response in the peripheral blood elements to a hemoglobin greater than 110 gm/l, a granulocyte count greater than 1 x 10(9)/l, and a platelet count greater than 100 x 10(9)/l (Catovsky criteria) was noted in all ten patients receiving alpha interferon but in only three of the patients undergoing splenectomy (P = less than .01). Median time to response was longer in the ten interferon patients (153 days) than in the three splenectomy responders (20 days). Median time to treatment failure was significantly greater in the alpha interferon patients (greater than 18 months) than in the splenectomy patients (less than 1 month). Survival was no different since patients relapsing following splenectomy subsequently responded to alpha interferon. A significant decrease in leukemic bone marrow infiltration was observed in seven of ten patients receiving alpha interferon and in none of the patients undergoing splenectomy. Side effects, primarily infections, were more frequent in patients receiving interferon. Alpha interferon is preferable to splenectomy as initial treatment for hairy cell leukemia.

Splenectomy in childhood: a review in England and Wales, 1960-4.

An investigation was carried out of 821 children under the age of 16 years who were subjected to splenectomy in England and Wales during the 5 years 1960-4. A postal follow-up study provided satisfactory information concerning 96 per cent of these. Excluding early postoperative deaths, practically all the cases were followed up for 2 years or more and 70 per cent for more than 5 years. Forty-nine children had died since operation, 32 from underlying disease and 17 from infection. Fifty children (6 per cent of the survivors) had major infections considered to be due to the primary condition aggravated by splenectomy. Seven died, all from the primary disease. Sixteen children (2 per cent) developed septicaemic illnesses and 10 died. In these the effect of splenectomy was considered to be the primary factor. Fourteen of the 16 had been operated on in the first 4 years of life. Practically all the serious infections occurred within 3 years of operation and pneumococcus was the organism most frequently implicated. Ninety per cent of the splenectomies in childhood were performed for accidental injury, congenital haemolytic anaemia or idiopathic thrombocytopenic purpura. Accidental injury to the spleen rarely occurs in very young children, and in the other two conditions splenectomy can usually be safely delayed untile over the age of 3 years. If this is achieved it is estimated that the unavoidable risk of dangerous infection is less than 1 per cent. One in 10 splenectomies will be carried out for severe and potentially fatal illnesses and in this situation the risk from operation is of secondary importance. Many such conditions carry increased susceptibility to infection per se or because corticosteroids or other immune suppressants are used in their management. It is recommended that splenectomy be avoided if at all possible during the early years of life. It is further recommended that prophylactic penicillin be administered for 3 years following operation whatever its indication and whatever the age of the patient. If the underlying condition itself carries risk of infection more active and more prolonged prophylaxis may be indicated.

Incidence of septic and thromboembolic-related deaths after splenectomy in adults.

In a review of 37,012 autopsies over the last 20 years 202 deceased adults who had had a splenectomy were investigated. The incidence of infections and thromboembolic complications related to death in these patients was compared with that of a matched deceased population (n = 403) who had not undergone splenectomy. Death-related pneumonia was diagnosed frequently in the splenectomy group and to a lesser extent in the control group (57.9 versus 24.1 per cent, P less than 0.001). Lethal sepsis with multiple organ failure occurred in 6.9 per cent of the splenectomy group and in 1.5 per cent of the controls (P less than 0.001). Purulent pyelonephritis was observed in 7.9 per cent of the splenectomy group and was significantly more frequent than in the control group with its rate of 2.2 per cent (P less than 0.001). Finally, pulmonary embolism was the major or a contributory cause of death more often in the splenectomy group than in the control group (35.6 versus 9.7 per cent, P less than 0.001). We conclude that splenectomy generates a considerable life-long risk of severe infection and of thromboembolism.

Splenic autotransplantation after splenectomy: tuftsin activity correlates with residual splenic function.

This study set out to determine the relationship between splenic function (as assessed by the percentage of pitted red cells) and tuftsin activity, and to confirm the return of effective splenic function after splenectomy for trauma. Twenty-three patients (13 men) took part. Ten of mean age 48.5 (range 30-74) years had had the spleen removed for traumatic rupture and 13 of mean age 49.7 (range 23-66) years had undergone elective splenectomy. At the time of the study all patients had had the spleen removed a minimum of 1 year previously (mean 6.1 (range 1-15) years). Fifty healthy volunteers matched for sex and age were also studied. In each subject, residual splenic function was evaluated by counting the percentage of pitted red cells. Tuftsin activity was also determined. A highly significant negative correlation was found between pitted red cell percentage and tuftsin activity (rs = -0.80, P < 0.001). Compared with healthy controls (mean 21.6 (range 13-37) per cent), tuftsin activity was significantly reduced both in patients who had undergone splenectomy for trauma (mean 4.4 (range 0-9) per cent; P < 0.0001) and in those who had had elective splenectomy (mean 0; P < 0.0001). Tuftsin activity was significantly (P < 0.001) more depressed after elective than traumatic splenectomy. These data confirm a decrease in tuftsin activity following splenectomy and show that this deficit is significantly greater after elective than emergency removal. These observations confirm that residual splenic function is often present after traumatic splenectomy.

Splenectomy as part of cytoreductive surgery for ovarian carcinoma.

Splenectomy is sometimes necessary to achieve optimal cytoreduction or manage iatrogenic injury in the surgical management of epithelial ovarian cancer (EOC) and related conditions. To determine the place of splenectomy in cytoreductive surgery a retrospective review was made of patient hospital records. Between April 1989 and August 1994, 18 patients were found to have undergone a splenectomy as a component of their surgery leading to optimal debulking. Morbidity attributable to the splenectomy was minimal, with no significant increase in operative time or blood loss. The morbidity attributable to the splenectomy was as follows: atelectasis and/or effusion (8), pancreatic tail injury (4), thrombocytosis > 10(6)/microliters (3), pancreatic pseudocyst (1), partial left adrenalectomy (1), and pulmonary embolism (1). There were no instances of overwhelming postsplenectomy infection. Five patients were anticipated to require splenectomy and may have benefitted from preoperative vaccination against potential pathogens. Three patients were found to have splenic parenchymal metastases. Consistent with the international literature, these patients had other features consistent with stage IV disease, recurrent disease, or poor survival. Consideration should be given to expanding the FIGO stage IV classification to include splenic parenchymal disease. Splenectomy is a feasible and safe procedure to facilitate optimal tumor debulking; however, the potential associated morbidity mitigates against this procedure if significant, suboptimal residual disease is left elsewhere.

Splenectomy and surgical cytoreduction for ovarian cancer.

OBJECTIVE: The aim of this study was to evaluate the role of splenectomy, as a surrogate marker for aggressive tumor cytoreduction in ovarian cancer, and its impact on patient morbidity and survival. METHODS: A retrospective cohort study of 35 patients who underwent splenectomy for ovarian cancer cytoreduction between August 1986 and May 1998 was performed. Data abstracted from the medical record included patient demographics, preoperative imaging, surgical procedures, tumor distribution, postoperative complications, chemotherapy treatment, and follow-up information. RESULTS: Splenectomy was performed in 13 patients at the time of primary cytoreduction and in 22 patients at the time of secondary cytoreduction. Preoperative diagnosis of splenic involvement was frequently made prior to secondary surgery, 77.3% compared to 15.4% of primary cases. In addition, parenchymal splenic involvement was more commonly observed at recurrence, 59.1% vs 23.1% at initial presentation. Disease distribution in secondary cytoreduction cases tended to be more focal, macronodular, and have no ascites. Cytoreduction to less than 1 cm disease was achieved in 100% of primary patients and 86% of secondary patients. Major morbidity (pneumonia, PE, sepsis, pancreatitis, MI) occurred in 23.1% of primary patients and 28.6% of secondary patients. Combining splenectomy with other cytoreductive procedures may make splenectomy itself seem more morbid. With a 17-month median follow-up, median progression-free interval was 24 months in primary patients and 14 months in secondary patients. Among secondary patients, median survival time after splenectomy and cytoreduction was 41 months. CONCLUSIONS: Splenectomy at the time of primary and secondary cytoreduction for ovarian cancer can be performed with acceptable morbidity. Secondary cytoreduction patients may be selected preoperatively by their progression-free interval, prior degree of cytoreduction, and macronodular tumor involvement on imaging studies. Identification of splenic involvement allows for appropriate counseling and preoperative preparation.

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.

Late results of splenectomy in hematologic disorders.

During the past 27 years from 1944 to 1970 splenectomy was performed on 53 patients including 33 idiopathic thrombocytopenic purpura (ITP), 13 hereditary spherocytosis and 7 hypoplastic anemia. Their clinical and laboratory findings in immediate and late postoperative periods were compared with those received medical treatment alone. In the chronic form of ITP the effect of medical treatment alone is only transitory and not curative. Splenectomy seems to be the treatment of choice in this situation which produces long term favorable results regardless of patient's response to preoperative steroid treatment. In hereditary spherocytosis the improvement in the morphology of red blood cells was limited after splenectomy, but considerable improvement was achieved in hemolytic tendency. Therefore, splenectomy would be the first choice. In hypoplastic anema splenectomy did not produce, in general, favorable results as compared in ITP or hereditary spherocytosis. However, when the patient responded to steroid treatment preoperatively, splenectomy could have reduced the frequency and amount of blood transfusion. Splenectomy would then be contemplated in such situations.

In vivo platelet activation and hyperaggregation in hemoglobin E/beta-thalassemia: a consequence of splenectomy.

Patients with hemoglobin E/beta-thalassemia (E/beta-Thal) who have undergone splenectomy are prone to thrombosis in the small pulmonary arteries. To study the role of platelets in this situation, we assayed plasma beta2-thromboglobulin (betaTG) and performed whole blood platelet aggregation analysis of 30 E/beta-Thal patients, half of whom had undergone splenectomy. We compared results with those obtained with 15 healthy control subjects. Plasma betaTG levels in splenectomy patients were significantly higher than in control subjects and patients who had not undergone splenectomy, and platelets in splenectomy patients exhibited hyperaggregation in response to adenosine diphosphate, thrombin, and ristocetin. Levels of plasma thrombin-antithrombin III complex were also significantly higher. This finding is likely due to an increased number of erythrocytes with exposed phosphatidylserines, an effect that has been associated with splenectomy. The increased presence of thrombin in the blood may well be the cause of platelet hyperactivity, which was evident only in the asplenic patients Platelet hyperactivity very likely plays a pathogenetic role in the thrombosis of small pulmonary arteries that occurs in E/beta-Thal patients who have undergone splenectomy.

Spleen-preserving distal pancreatectomy with excision of splenic artery and vein: a case-matched comparison with conventional distal pancreatectomy with splenectomy.

BACKGROUND: The value of spleen preservation during distal pancreatectomy (DP) still remains controversial. Spleen-preserving DP with excision of the splenic artery and vein is a simplified technique for spleen preservation. The aim of this study was to compare the postoperative course of DP with or without splenectomy. PATIENTS AND METHODS: From 1990 to 2005, 38 consecutive patients with benign or low-grade malignant disease underwent a spleen-preserving DP operation with excision of the splenic artery and vein (Conservative Group). They were compared with 38 patients who underwent conventional DP with splenectomy over the same time period (Splenectomy Group) and who had been matched for age, American Society of Anesthesiologists (ASA) score, and pathological diagnosis. Postoperative courses were analyzed and compared between the Conservative Group and Splenectomy Group. RESULTS: Spleen preservation was effective in 36 of the 38 attempts (95%). Postoperative complications - in particular, infectious intra-abdominal complications - were significantly higher in the Splenectomy Group (34 and 18%, respectively) than in the Conservative Group (13 and 3%, respectively) (P = 0.03 and P = 0.02, respectively). The length of the surgery, perioperative blood loss or transfusions, perioperative mortality and length of hospital stay did not differ between the two groups. Univariate analysis showed that splenectomy was the only risk factor for postoperative complication. CONCLUSIONS: Spleen-preserving DP with excision of the splenic artery and vein is a fast, safe and effective procedure associated, in this series, with a reduction of postoperative complications relative to conventional DP with splenectomy. This technique should be considered in patients with benign or low-grade malignant disease of the pancreas.

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.

Laparoscopic subtotal splenectomy in hereditary spherocytosis : to preserve the upper or the lower pole of the spleen?

BACKGROUND: Clinical manifestations of hereditary spherocytosis can be controlled by splenectomy. The use of this procedure has been restricted due to concerns regarding exposure of patients to a lifelong risk of overwhelming infections. Subtotal splenectomy, which removes 85-90% of the enlarged spleen, is a logical alternative. In the first cases performed by laparoscopy we have chosen to preserve the upper pole. However, this technique showed some disadvantages, especially concerning the correct intraoperative evaluation of the splenic remnant volume. Therefore, we developed a new variant of the procedure by preserving the lower pole of the spleen. METHODS: Based on the authors' experience in laparoscopy (176 laparoscopic splenectomies), 10 laparoscopic subtotal splenectomies were performed in patients with hereditary microspherocytosis, preserving either the upper or the lower splenic pole. RESULTS: Patient age ranged between 5 and 35 years. The mean volume of the remnant spleen was 41.4 cm3. There were no complications, and no transfusions were needed. Follow-up for 1-30 months was available. CONCLUSIONS: Subtotal splenectomy appears to control hemolysis while maintaining splenic function. The laparoscopic approach is safe and effective and should be considered the procedure of choice in hereditary microspherocytosis. Laparoscopic subtotal splenectomy presents an advantage over open subtotal splenectomy, resulting in decreased blood loss, shorter hospital stay, no conversions, fewer operative and postoperative complications, and excellent remission rates. On the basis of our experience, the preservation of the lower pole of the spleen seems to be a first-line option for the optimal evaluation of the residual splenic mass.

Laparoscopic splenectomy and nephrectomy in a rat model. Description of a new technique.

BACKGROUND: In experimental studies on the effects of laparoscopic procedures on tumor biology, a localized tumor model is desirable. The spleen and the kidney are preferable, because these organs are amenable to tumor placement and subsequent removal. This study describes the technique of laparoscopic splenectomy and nephrectomy in the rat model. METHODS: Pneumoperitoneum was established by CO2 insufflation. Laparoscopic splenectomy involved two-handed dissection, intracorporeal ligation, and division of gastrosplenic attachments and hilar and short gastric vessels. Laparoscopic nephrectomy was done by intracorporeal ligation and division of the renal vessels and the ureter after mobilization of the kidney. RESULTS: Laparoscopic splenectomy was performed in six rats; laparoscopic nephrectomy was done in six rats. Operative time ranged from 45 to 90 min for splenectomy and from 40 to 65 min for nephrectomy. Postoperatively, two rats died from hemorrhage. Necropsy of the rats after 10 days revealed adhesion in three rats after splenectomy and in four rats after nephrectomy. Inflammatory processes were found around the silk ligatures in all rats after splenectomy; in two rats wound infections occurred at the port sites. CONCLUSIONS: Laparoscopic splenectomy and nephrectomy in the rat proved technically feasible and may provide new localized tumor models suitable to be used in further studies on the oncological effects of laparoscopic surgery.

Laparoscopic splenectomy for idiopathic thrombocytopenic purpura. A 1-year follow-up study.

BACKGROUND: Laparoscopic splenectomy is a novel approach for the treatment of idiopathic thrombocytopenic purpura (ITP) in patients requiring surgical intervention. This technique was used for treatment in 16 consecutive patients. Follow-up was initiated at a median of 13.5 months after surgery to determine whether or not laparoscopic splenectomy is a safe and successful procedure that should be used in all patients requiring splenectomy for ITP. METHODS: Sixteen patients underwent laparoscopic splenectomy for ITP between May 1994 and September 1996. They were evaluated prospectively prior to surgery, immediately following surgery, at discharge, and at 13.5 months following surgery (n = 14) to determine the short- and long-term results of the procedure. RESULTS: Mean operation time was 123.4 +/- 12.1 min, and there were no significant intra- or postoperative complications. Mean intraoperative blood loss was 437.5 +/- 73.5 ml. Autologous blood transfusion was necessary in one patient (6.3%). Mean organ weight was 202.2 +/- 47.3 g. Mean postoperative hospital stay was 4.6 +/- 0. 4 days. Before discharge, mean platelet count rose by 100.7%. At follow-up (13.5 months postoperatively), it was 77.7% above preoperative values. No additional surgery was necessary in any of the patients undergoing laparoscopic splenectomy, and hematologic success was achieved in 12 patients (85.7%). CONCLUSIONS: Our results clearly indicate that laparoscopic splenectomy is a safe and successful procedure in patients suffering from ITP. It offers the well-known advantages of minimal invasive surgery as well as the surgical effectiveness of the open approach. This surgical technique should therefore be considered in all patients requiring splenectomy for the treatment of ITP.
