[Laparoscopic resection of benign submucosal stomach tumors. A report of 65 cases].

AIM OF THE STUDY: The aim of this retrospective multicenter study was to evaluate the feasibility and the results of laparoscopic resection of benign submucosal gastric tumors. PATIENTS AND METHODS: We reviewed the cases of 65 patients (20 centers) who have been operated on laparoscopically for benign submucosal gastric tumors. The tumor was symptomatic in 56 cases, located on the posterior wall in 23 cases. The mean size of the tumor was 3.8 cm (1.5-10). RESULTS: A laparoscopic wedge resection was performed in 53 cases. In 1 case a laparoscopic-assisted gastrectomy was done. A conversion to laparotomy was mandatory in 11 cases because of difficulties in localization of the tumor (n=5), in excision (n=5) or for safety reasons (n=1). There was no mortality. Two patients required reoperation because of bleeding. During follow-up, one patient developed recurrence requiring a second laparoscopic excision. CONCLUSION: Most submucosal benign gastric tumors can be removed by laparoscopy. The location of the tumor (posterior wall or closed to the lesser curvature) or the size of the tumor (large or very small) can make the laparoscopic approach difficult.

Laparoscopic splenectomy for idiopathic thrombocytopenic purpura.

We conducted a retrospective multicenter study by questionnaire to evaluate the results of laparoscopic splenectomy for idiopathic thrombocytopenic purpura (ITP). Between 1991 and 1998, 209 patients with a mean age of 41.2 years (range, 10-83) had a laparoscopic splenectomy for idiopathic thrombocytopenic purpura. Preoperatively, 178 patients (85%) underwent medical treatment aimed at achieving a satisfactory platelet count. Twenty-nine patients were obese, with a body mass index greater than 30%, and 14% were HIV-seropositive. The so-called hanging spleen technique in the right lateral decubitus position was used most often. The average duration of surgery was 144 minutes (45-360). This was significantly longer in cases of conversion (170 minutes; P < 0.01). The factors influencing the duration of laparoscopy were operator experience and patient obesity (P < 0.01). A conversion was necessary in 36 cases (17.2%) because of hemorrhage. The conversion rate varied from 5.3% to 46.7%, depending on the surgical team. A multivariate analysis of factors disposing to conversion identified two causes: obesity and operator experience. One or more accessory spleens were found in 34 patients (16.2%). The average weight of the spleens was 194.2 g. There were no deaths. There were no complications in 187 patients (89.5%), with a mean hospital stay of 6.1 days. Patients who did not require a conversion had a significantly earlier return of intestinal transit, used less analgesic, and had a shorter length of hospitalization. Overall morbidity was 10.5% (22 cases), due to subphrenic collections (7 cases), abdominal wall complications (6 cases), re-intervention for actual or suspected hemorrhage or pancreatitis (3 cases), pneumopathology (2 cases) and others (4 cases). A multivariate analysis about morbidity shows a statistically significant difference in conversions (P < 0.05) but not in obesity or in surgeon's experience. Normal activity was achieved on average by the twentieth postoperative day--earlier if conversion was not required (18.4 versus 33.9 days). The average preoperative platelet count was 92.7 x 10(9)/L (range, 3 to 444). Twenty patients had a count of less than 30 x 10(9)/L and in this group the conversion rate was 30% (6 cases). Ninety-six patients were seen in the outpatient clinic, with an average follow-up time of 16.2 months (3 to 72 months), and the average platelet count was 242 x 10(9)/L (6 to 780). Eight patients (8.3%) were failures with a platelet count of <30 x 10(9)/L. In the 20 patients with a preoperative platelet count <30 x 10(9)/L, there were 3 early failures and 5 late relapses. There were 2 late deaths: chest infection at 3 months in an HIV seropositive patient and one case of pulmonary embolus at 6 months. Laparoscopic splenectomy constitutes a real alternative to conventional splenectomy for the treatment of idiopathic thrombocytopenic purpura. It is associated with fewer postoperative complications, a shorter duration of hospitalization and an earlier return to normal activity. The limiting factors are the experience of the operator and patient obesity. The long-term results are identical to those of conventional splenectomy, with a better than average success rate in patients that have failed preoperative medical treatment.
