Infected necrotizing pancreatitis is the most fulminant variety of this disease. Colonic involvement and retroperitoneal fasciitis are particularly lethal. The reported mortality is up to 50%. The purpose of this study is to review our combined experience at the Princess Alexandra Hospital and the Royal Brisbane Hospital, Brisbane, to determine whether patient survival was related to a particular etiology, treatment, or complication. All patients treated since 1986 with infected pancreatitis who required surgical necrosectomy and then ventilation in the intensive care unit (ICU) were studied. There were 48 patients so managed. The median age of survivors was 52 years, and for those who died it was 64 years (p = 0.001). The etiology was gallstones in 22 and alcoholism in 12. Of the alcoholics, 11 survived and 1 died. Of the patients with gallstones, 13 survived and 9 died. There was an overall mortality of 31%. Survivors were in hospital for a median of 73 days, whereas deaths occurred after a median of 35 days (p = 0.04). Seven patients underwent hemofiltration; five survived, and two died. N-Acetylcysteine has been used in four patients, of whom three survived and one died. The abdomen was left open in 38 patients and kept closed in 10. Although Ranson's criteria at admission to the ICU did not predict survival, it was found that the median APACHE II score in survivors was significantly lower than in those who died (p = 0.025).(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-one patients underwent laparoscopic common bile duct exploration during a 9 month period. Ten had stones flushed after ampullary dilatation. Seven had stones removed with a Dormier basket and one had direct common duct incision with T-tube insertion. Three failed attempted stone flushing and had stones removed by endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy. Operating time ranged from 1.5 to 3.5 h. Nineteen patients were discharged by the second postoperative day. This early experience with laparoscopic stone removal is encouraging, reducing the need for pre-operative or postoperative ERCP

The advent of laparoscopic cholecystectomy (LC) has led to some controversy regarding the best method of managing bile duct calculi. This paper reviews the cases of 38 patients who underwent LC and endoscopic retrograde cholangiopancreatography (ERCP), from a series of 600 consecutive laparoscopic cholecystectomies. Twenty-nine patients had ERCP performed pre-operatively because of suspicion of choledocholithiasis. Duct stones were confirmed in eight patients. Recent or current jaundice was the best predictor of bile duct stones. Nine patients had ERCP done postoperatively because of duct stones seen on operative cholangiography. In two patients bile duct cannulation was not possible and a third procedure, open duct exploration, was necessary. Techniques in laparoscopic management of duct stones are improving and the role of ERCP and sphincterotomy should be limited to jaundiced patients or those with proven bile duct stones in whom laparoscopic procedures have been unsuccessful

Sixty-eight cases of acute cholecystitis managed by laparoscopic cholecystectomy (LC) are reviewed. Thirty-two patients were admitted up to 10 days after onset of symptoms and 31 were completed by LC. One patient was referred from intensive care with gangrenous acalculus cholecystitis and was completed by LC but required subsequent laparotomy to control a bleeding omental vessel. Five patients were admitted with recurrent attacks of pain and histology confirmed resolving acute cholecystitis. Thirty patients had LC on routine operating lists, having recently had pain within 10 days of admission. Histology confirmed acute cholecystitis or resolving acute cholecystitis in these patients. All were completed by LC. Laparoscopic cholecystectomy is a very effective treatment for acute cholecystitis if complete dissection of anatomy can be performed

A consecutive series of 220 laparoscopic cholecystectomies (June 1990 to May 1991) is presented. These were the author's initial experience of the technique. Procedures were elective (205) and acute (15), including 3 gangrenous cholecystitis and 4 empyema. There were 166 females and 34 males, 12-75 years, weighing 44-115 kg. Forty-eight patients had prior abdominal surgery. Two hundred and eleven patients had successful laparoscopic cholecystectomies, 6 open cholecystectomies and 3 mini-laparotomies to remove split stones. None of the last 120 cases were opened. Operating time ranged from 20 min to 3 h 20 min. There were 4 serious complications: 2 bile leaks from the gall-bladder bed and 2 jejunal injuries (Veres needle and 5 mm trocar). Sixty-one patients were discharged the next day, 29 on day 2, 5 on day 3, 4 on day 4, 1 on day 5, 1 on day 22 and 1 on day 27. At two weeks follow-up all but 2 patients had fully recovered

The cause, management and outcome of 23 patients with a pancreatic fistula following acute pancreatitis are reviewed. Nineteen patients developed an external fistula following necrosectomy or drainage of a pancreatic abscess or pseudocyst; four of these patients died. In the 15 survivors spontaneous closure occurred in 11 cases with low output fistulae; operative intervention was needed in the four cases with high output fistulae. Four patients with internal fistulae had not undergone previous surgery; two of them had a pancreaticopleural fistula with associated pancreaticogastric fistulae, while two had pancreatic ascites. All four of these patients required surgical intervention and one died

The clinical course of 143 patients with gallstone pancreatitis is reviewed. Thirty-one patients (22%) had three or more positive prognostic factors on admission and 24 (77%) of these had a complicated course. Thirteen patients died, giving an overall mortality rate of 9%. Patients were divided into three groups on the basis of performance and timing of surgery. In group 1 (n = 56), surgery was undertaken during the first admission with acute pancreatitis; eight of these patients had a complicated course and three died. In group 2 (n = 40), biliary surgery was deferred to a subsequent admission; none of these patients died but 10 experienced further attacks of pancreatitis while awaiting reoperation. Group 3 patients (n = 47) did not undergo surgery; nine patients were diagnosed as having gallstone pancreatitis for the first time at autopsy, five refused operation, seven were lost to follow-up, six were dealt with by endoscopic sphincterotomy, and in 20 cases surgery was not considered appropriate because of general debility or advanced age. Despite the zero mortality rate in group 2, it is advocated that biliary surgery be carried out during the index hospital admission. Endoscopic sphincterotomy can now be considered as an alternative to cholecystectomy and duct clearance in the elderly and unfit, and may be used as a preliminary manoeuvre when severe acute pancreatitis fails to settle promptly on conservative management
