Arterial erosions in acute pancreatitis.

Acute pancreatitis was observed in 492 patients. Fourteen (2.8%) developed an arterial erosion revealed by a haemorrhage either in the digestive lumen, in the peritoneum or via previously placed drainage. The eroded artery was the splenic artery in six patients, a pancreatico-duodenal artery in five patients. An initial haemostasis was attempted by: a) embolization in four patients: one died; the three others had bleeding recurrence. b) splenocorporeal pancreatectomy in four patients, three had bleeding recurrence. c) arterial ligature in four patients: three had bleeding recurrence. Secondary haemostatic procedures were performed in ten patients but a durable haemostasis was achieved in only five patients: two had a pancreatic resection and three were treated by a redo-binding. It is noteworthy that durable haemostasis could not be obtained neither by embolization nor by ligature in necrotic tissues. This could explain the difference in the results of arterial erosion treatments in chronic and in acute pancreatitis. Therefore, it is suggested that haemostatic procedures should be performed away from necrotic tissues, or eventually done after their removal.

Cecostomy is a useful surgical procedure: study of 113 colonic obstructions caused by cancer.

PURPOSE: There is a large choice of treatment for obstructing carcinoma of the left colon. We report our experience of tube cecostomy as the initial treatment for obstructing colonic carcinoma followed by elective resection. METHODS: From 1975 to 1995, 113 patients presenting with colonic obstruction caused by cancer were initially treated by tube cecostomy. RESULTS: The cecostomy was performed under local anesthesia in 26 cases (23 percent) and general anesthesia in 87 cases (77 percent). In the postoperative period 15 patients died (13 percent) and 26 (23 percent) had wound infection in the area around the cecostomy. A second operation performed on the 98 surviving patients comprised 74 left colonic resections with anastomosis, 9 without anastomosis (Hartmann's operation), 1 right colectomy, 3 total colectomies eliminating the cecostomy, 3 internal bypasses, and 8 proximal lateral colostomies. Surgical closure of the cecostomy was performed during six of the second operations. No deaths occurred from any of the second operations. The cecostomy closed spontaneously in 78 patients (89 percent). In ten cases (11.4 percent) a third operation was performed to close the cecostomy, without mortality. CONCLUSIONS: Comparison our cecostomy results with published studies of proximal diverting loop colostomies for the same indications showed comparable mortality after the first operation. Cecostomy decrease mortality of the second operation. This retrospective study suggests that cecostomy is a useful and less invasive surgical procedure for patients presenting with colonic obstruction caused by cancer.
