[Comparison of laparoscopic splenectomy in supine position with hanging-spleen technique in idiopathic thrombocytopenic purpura]. / Vergleich der laparoskopischen Splenektomie in Steinschnittlage mit der Hanging-Spleen-Technik bei idiopathischer thrombozytopenischer Purpura.

BACKGROUND: Laparoscopic splenectomy has become the gold standard intervention for elective splenectomy. Several techniques have been described, which differ in trocar localisations and patient positions. The hanging-spleen technique was examined in comparison to the conventional laparoscopic splenectomy in the supine position among the patient population in our institution over a period of 8 years. PATIENTS AND METHODS: On the basis of a retrospective analysis, data were collected on all patients who underwent elective laparoscopic splenectomy for idiopathic thrombocytopenic purpura between May 1994 and April 2002 and were examined for operation time, blood loss and peri-operative complications. Two types of operation were compared, the conventional laparoscopic splenectomy in the supine position (group A) and the hanging-spleen technique (group B). Finally, the costs of materials of the two operation techniques were compared. RESULTS: For 51 patients (43.1 % men, 56.9 % women) (mean age: 45.5 ± 17.5 years) the mean operation times were 134.2 ± 47.3 min (group A) and 9.8 ± 39.9 min (group B). The mean blood losses were 691.3 ± 544.4 mL in group A and 638.3 ± 1050.6 mL in group B. The perioperative complications were 38.8 % in group A and 21.2 % in group B. There was no significant difference found for operation time, blood loss and perioperative complications in a multivariate analysis. The cost of materials was reduced in group B (use of Endo-GIA 42.4 % in group B, 100 % in group A). In group A 4 incisions, in group B 3 incisions were necessary. CONCLUSIONS: Regarding operation time, blood loss and perioperative complications the 2 laparoscopic techniques for splenectomy do not differ significantly. Merely reduced material costs and a reduction of incisions were found in patients -operated with the hanging-spleen technique. Whether the hanging-spleen technique is the method of choice will have to be shown by further prospective studies.

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.

Laparoscopy improves outcomes for pediatric splenectomy.

BACKGROUND: Pediatric laparoscopic splenectomy is a relatively new surgical procedure with a limited number of reports comparing its outcomes to that of the open procedure. The authors have minimized the invasiveness of our procedure by using only three ports and have described the technique as well as compared it with the open method. METHODS: A retrospective review of seven laparoscopic splenectomies (LS) using a three port technique were compared with seven open splenectomies (OS) performed for similar indications at a single children's hospital. RESULTS: The average age in the LS group was 8.7 years compared with 8.9 years for OS, (P value not significant), and the average weights were also similar. The indications for splenectomy were hereditary spherocytosis, idiopathic thrombocytopenic purpura, sickle cell anemia, and splenic cyst. All splenectomies were performed safely with an average estimated blood loss of 41 mL for LS and 34 mL for OS (P value not significant). Operative time averaged 147 minutes for LS and 86 minutes for OS (P < .05). LS patients recovered more rapidly and were discharged home on a median of postoperative day (POD) 2 versus POD 4 for OS (P < .05). LS patients received significantly less total amount of intravenous pain medication with an average of 0.18 mg/kg of morphine sulfate versus 0.8 mg/kg for OS (P< .05). Total hospital charges were higher for LS with an average of $10,899 versus $8,275 for OS (P < .05). CONCLUSIONS: Laparoscopic splenectomy currently is a safe procedure, offering better cosmesis, much less pain, and a shorter hospital stay compared with the traditional open procedure. The more sophisticated equipment and time needed to carry out the procedure led to a modestly increased hospital cost.

Laparoscopic splenectomy for idiopathic thrombocytopenic purpura: comparison of laparoscopic surgery and conventional open surgery.

In chronic idiopathic thrombocytopenic purpura (ITP), the two main therapeutic choices are steroid treatment or splenectomy. The adult form of ITP is described as a disease found primarily in young adults, with a female predominance. Treatment with steroids effects a complete response in less than 30% of patients, whereas splenectomy is successful in more than 60% of patients who undergo it. The minimal access afforded by laparoscopic splenectomy is considered highly desirable for these patients. The purpose of this study was to compare the clinical benefits of a laparoscopic splenectomy with those of conventional open surgery for patients with ITP. From 1968 to 1993, splenectomy was performed on 51 patients: 10 operations done laparoscopically and 41 performed conventionally. Complications, postoperative pain, recovery, and hospital charges were then compared. Laparoscopic splenectomy involved minimal incisions, and a significantly lower frequency of analgesia was required for postoperative abdominal pain (1.3 vs. 3.3); hospital stay was shorter (8.2 vs. 20.1 days) (p < 0.005). Operative time was significantly longer for the laparoscopic surgery (249.2 vs. 99.8 min) (p < 0.0001), but blood loss was less (176.0 vs. 511.7 g) (p < 0.01). No intraoperative or postoperative major complications occurred with the laparoscopic procedures, compared with 46.3% with conventional surgery. Finally, the total hospital costs were lower with laparoscopic splenectomy, especially for postoperative care (p < 0.05). A laparoscopic splenectomy may well be considered the surgical treatment of choice for patients requiring a splenectomy in view of both quality of life and economy.
