Outcome of laparoscopic splenectomy based on hematologic indication

BACKGROUND: Laparoscopic splenectomy is the procedure of choice for elective splenectomy at the Cleveland Clinic Foundation. Although the literature clearly documents the technical feasibility and safety of laparoscopic splenectomy, little data exists concerning the results of this procedure based on the hematologic indication for splenectomy. We sought to examine the clinical experience with laparoscopic splenectomy in a single institution, with particular attention to morbidity and clinical outcomes based on hematologic disease process. METHODS: This study retrospectively reviewed a consecutive series of laparoscopic splenectomies performed for nontraumatic, splenic pathology at the Cleveland Clinic Foundation from August 1995 to January 2001. Patient demographics, operative indications, morbidity, mortality, and clinical outcome were evaluated. Hematologic diagnostic groups were compared using Fisher's exact tests and Wilcoxon rank-sum tests. RESULTS: A total of 147 laparoscopic splenectomies were performed. Seven patients (5%) required conversion to open splenectomy. Indications for splenectomy included idiopathic thrombocytopenic purpura (ITP) in 65 patients, hematologic malignancy in 43 patients, autoimmune hemolytic anemia (AIHA) in 9 patients, thrombotic thrombocytopenic purpura (TTP) in 9 patients, splenomegaly in 5 patients, splenic cyst in 4 patients, splenic abscess in 3 patients, hereditary spherocytosis in 2 patients, splenic artery aneurysm in 2 patients, Felty's syndrome in 1 patient, myelofibrosis in 1 patient, and other in 3 patients. Accessory spleens were identified in 20 patients (14%). Postoperative complications occurred in 23 (16%) patients. Patients with ITP had significantly shorter operation times (134 vs 163 min; p = 0.001), decreased estimated blood loss (126 vs 307 ml; p = 0.001), decreased length of hospital stay (2.8 vs 4.6 days; p < 0.001), and less chance of conversion (0 vs 7; p = 0.02) than patients with any other diagnosis. A mean follow-up period of 20 +/- 14 months showed an 85% rate of remission for ITP, 89% for TTP, and 89% for AIHA. Patients with malignant disease had significantly larger spleens (822 vs 313 g; p < 0.001), more estimated blood loss (380 vs 168 ml; p = 0.04), and longer operative times (170 vs 142 min; p = 0.009), as compared patients treated for benign disease. However, the length of hospital stay (4.3 vs 3.6 days; p = 0.06) and complication rates (19% vs 14%; p = 0.08) were not significantly different between the two groups. CONCLUSIONS: When performed for ITP, laparoscopic splenectomy resulted in shorter operations, minimal blood loss, earlier discharge, no conversions, and excellent remission rates, as compared with other hematologic indications. Despite larger spleens, more blood loss, and longer operations in patients with hematologic malignancies, morbidity and length of hospital stay still were similar to those associated with benign indications for laparoscopic splenectomy. In conclusion, laparoscopic splenectomy is safe and efficacious for a multitude of benign and malignant hematologic indications, and our data compares favorably to those for open series.     

Laparoscopic splenectomy: a selected retrospective review

Previous investigators have suggested that laparoscopic splenectomy should be the procedure of choice for the treatment of benign hematologic disorders unresponsive to medical therapy. To evaluate the safety and utility of laparoscopic splenectomy for a variety of splenic disorders, we reviewed our collective experience at 2 institutions. We studied our 8-year experience by retrospective chart review. Patient demographic data, splenic pathology, intraoperative events, concomitant procedures, and all adverse perioperative events were recorded. A total of 131 patients had laparoscopic splenectomy, and there were 8 conversions to open surgery. Pathology included 63 with idiopathic thrombocytopenic purpura (ITP), 23 malignancies, 12 thrombotic thrombocytopenic purpura (TTP), 10 autoimmune hemolytic anemia (AIHA), and 23 others. Accessory spleens were noted in 21 patients (16%). Concomitant surgical procedures included 12 hepatic biopsies, 4 distal pancreatectomies, 4 cholecystectomies, and 7 others. Mean operative time was 170 minutes. There were 16 major complications in 16 patients and 2 deaths. Median postoperative length of stay was 3 days. Conversions, due mostly to bleeding, are related to splenic pathology and medical comorbidity and are not temporally related to surgical experience (learning curve). The morbidity, mortality, and conversion rates were low. Laparoscopic splenectomy permits an appropriate abdominal exploration and is associated with a short hospital stay. It is the procedure of choice for most indications for splenectomy.     

Laparoscopic splenectomy reduces the need for platelet transfusion in patients with idiopathic thrombocytopenic purpura.

OBJECTIVES: Laparoscopic splenectomy has been increasingly used in patients with idiopathic thrombocytopenic purpura. Because it is associated with minimal abdominal trauma, platelet consumption could be reduced with the laparoscopic approach. The aim of this study was to analyze intraoperative bleeding and the need for apheresis platelets, comparing laparoscopic with open splenectomy. METHODS: Records of 40 patients who underwent splenectomy (20 through laparoscopy and 20 through open surgery) for idiopathic thrombocytopenic purpura were retrospectively reviewed. Intraoperative bleeding and need of perioperative apheresis platelets were evaluated in both groups. Statistical evaluation was conducted using the Mann-Whitney rank test, and differences were considered significant at P<0.01. RESULTS: The mean amount of intraoperative bleeding was less in the laparoscopic group (P<0.01). Apheresis platelets were necessary in all patients in the open group (2 units transfused in 55% and 1 unit in 45% of cases) and only in 30% of cases in the laparoscopic group (1 unit transfused in each case). CONCLUSIONS: Laparoscopic splenectomy is a safe procedure also in patients at high risk for bleeding diathesis. In idiopathic thrombocytopenic purpura, laparoscopic splenectomy should be the gold-standard surgical treatment. Need of platelet transfusion is probably reduced when laparoscopic splenectomy is compared with open surgery in these patients.

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.

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   

Laparoscopic splenectomy

PURPOSE: To study the safety and efficacy of laparoscopic splenectomy (LS) in patients with hematologic disorders requiring surgical intervention. PATIENTS AND METHODS: A series of 103 consecutive adult patients underwent LS between 1992 and 1997 at our teaching hospital. Data were collected prospectively. The indications for splenectomy included idiopathic thrombocytopenic purpura (ITP), hereditary spherocytosis, autoimmune hemolytic anemia, and thrombotic thrombocytopenic purpura. RESULTS: The mean spleen size was 14 cm (range 8.5-24 cm) and the mean weight was 263 g (range 40-210 g). Accessory spleens were detected in 12 patients with ITP and 17 patients in the study overall. In 12 patients, LS was combined with a laparoscopic cholecystectomy for gallstones. There were four conversions to open splenectomy, all for hemorrhage and all occurred in the first 50 patients. We have not converted a single patient in the last 2 years. The mean operative time was 161 minutes and was greater in the first 10 cases than the last 10. There were no deaths. Postoperative complications occurred in six patients, one necessitating a second procedure for a small-bowel obstruction. The average length of stay in the hospital was 2.5 days. After surgery, thrombocytopenia resolved in 84% of patients with ITP and anemia resolved in 92% of the patients with hereditary spherocytosis. After a mean follow-up of 38 months (range 2-565 months), four patients (6%) showed a relapse of ITP, three within 12 months of surgery. CONCLUSIONS: Laparoscopic splenectomy can be performed safely and effectively in a teaching institution. LS in comparison with open surgery offers the same efficacy in the control of hematologic disease with the additional benefits of a minimally invasive approach. Laparoscopic splenectomy should therefore be considered the technique of choice and should prompt earlier consideration of surgery for patients with selected hematologic disorders.     

Laparoscopic splenectomy: outcome and efficacy in 103 consecutive patients.

OBJECTIVE: To study the safety and efficacy of laparoscopic splenectomy (LS) in patients with predominantly benign hematologic disorders. SUMMARY BACKGROUND DATA: The technical feasibility of LS has been recently established. However, data regarding the efficacy of the procedure in a large cohort of patients are scarce. METHODS: One hundred three consecutive patients underwent LS between June 1992 and October 1997. Data were collected prospectively on all patients. RESULTS: Indications were idiopathic thrombocytopenic purpura (ITP), hereditary spherocytosis, autoimmune hemolytic anemia, thrombotic thrombocytopenic purpura, and others. Mean spleen size was 14 cm and mean weight was 263 g. Accessory spleens were found in 12 patients with ITP and in 5 patients without ITP. There were no deaths. Complications occurred in six patients, one requiring a second procedure for small bowel obstruction. Six patients received transfusions, and four procedures were converted to open splenectomy for bleeding. Mean surgical time was 161 minutes and was greater in the first 10 cases than the last 10. Mean postsurgical stay was 2.5 days. Thrombocytopenia resolved after surgery in 84% of patients with ITP, and hematocrit levels increased significantly in 70% of patients with chronic hemolytic anemias. A positive response was noted in 92% of patients with hereditary spherocytosis, without relapse for the duration of the observation. ITP relapsed in four patients during follow-up, three within 12 months. CONCLUSIONS: LS can be performed safely and effectively in a teaching institution. Rigorous technique will minimize capsular fractures, reducing the risk of splenosis. Accessory spleens can be successfully localized, thus improving response and limiting recurrence of ITP. LS should become the technique of choice for treatment of intractable benign hematologic disease.

Laparoscopic Splenectomy for Idiopathic Thrombocytopenic Purpura: Outcome and Long-term Results

The technical feasibility of laparoscopic splenectomy (LS) has been recently established. However, data regarding the efficacy of the procedure with long-term follow-up of patients with idiopathic thrombocytopenic purpura (ITP) are scarce. The objective of this study was to determine retrospectively the immediate efficacy and the long-term results of a standardized laparoscopic procedure applied to patients with ITP refractory to medical treatment. Laparoscopic splenectomy was performed in 35 patients for ITP between May 1993 and May 1998. The lateral approach was used in the last 27 patients. Data were recorded retrospectively on that group. Twenty-six patients (96%) underwent successful LS. Mean operative time for the laparoscopic procedure was 90 minutes. There were no postoperative deaths. Postoperative complications developed in three patients. Thrombocytopenia resolved after surgery in 93% of patients, but 7 patients (25%) experienced relapse during a mean 28-month follow-up. At present no patient needs medical therapy to maintain a normal platelet count. Laparoscopic splenectomy is feasible and safe in patients with ITP. Long-term results of LS for ITP are comparable to those achieved with open splenectomy.

Laparoscopic splenectomy is a safe and effective procedure for patients with splenomegaly due to portal hypertension

BACKGROUND/PURPOSE: This study was conducted retrospectively to examine whether laparoscopic splenectomy is an effective procedure for patients with splenomegaly due to portal hypertension in comparison to patients with a normal-sized spleen. METHODS: From September 1994 to May 2005, we performed laparoscopic splenectomy in 50 patients at Wakayama Medical University Hospital, Japan. Of these, 17 patients with splenomegaly due to portal hypertension and 17 patients with idiopathic thrombocytopenic purpura (ITP) with normal-size spleen were enrolled in this study, in which we compared the surgical outcome between patients with splenomegaly due to portal hypertension and those without splenomegaly (ITP group). RESULTS: The mean operative time (splenomegaly due to portal hypertension vs ITP; 171 vs 165 min; P = 0.7433) and estimated blood loss (248 vs 258 ml; P = 0.5396) were similar in the two groups. There were two patients with complications (11.8%) in the patients with splenomegaly due to portal hypertension and five patients with complications (29.4%) in those with ITP. All patients with splenomegaly due to portal hypertension showed appropriate increases in the platelet count following surgery. No perioperative mortality occurred. CONCLUSIONS: We concluded that laparoscopic splenectomy was an effective procedure for splenomegaly due to portal hypertension, with findings being similar to those observed in patients with a normal-sized spleen (such as patients with ITP).

Laparoscopic splenectomy for idiopathic thrombocytopenic purpura

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.

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.     

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.
