Early ERCP is an essential part of the management of all cases of acute pancreatitis.
(1/201)
The role of early endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy in acute pancreatitis is controversial. Recent randomised controlled trials mostly support the value of this procedure, but concerns remain as to its safety, efficacy and practicability. This debate critically assesses the evidence for and against the use of early ERCP in acute pancreatitis. (+info)
Ultrasonographic evaluation of the common bile duct in biliary acute pancreatitis patients: comparison with endoscopic retrograde cholangiopancreatography.
(2/201)
We compared the morphologic findings of the common bile duct by ultrasonography and endoscopic retrograde cholangiopancreatography in patients with biliary acute pancreatitis. Forty-five patients were studied. The diagnosis of acute pancreatitis was based on the presence of characteristic abdominal pain associated with an elevation of serum amylase and lipase concentrations. All patients underwent ultrasonography and subsequently urgent endoscopic retrograde cholangiopancreatography and eventually endoscopic sphincterotomy. Ultrasonography showed gallstones in 33 patients and sludge of the gallbladder in seven patients. In the common bile duct, lithiasis was found in two patients and sludge in 25. Endoscopic retrograde cholangiopancreatography showed choledocolithiasis in eight patients and sludge of the common bile duct in 32. In 27 cases (60%) concordance occurred between ultrasonographic and endoscopic retrograde cholangiopancreatographic detection of lithiasis or sludge of the common bile duct. The average diameter of the common bile duct determined by sonography was significantly smaller (P < 0.001) than that obtained by endoscopic retrograde cholangiopancreatography. The evaluation of this parameter indicated that a good correlation existed between the values obtained with the two techniques (r(s) = 0.765, P < 0.001). Both ultrasonography and endoscopic retrograde cholangiopancreatography can provide reliable measurements of the common bile duct diameter. Ultrasonography is the technique of choice in the initial investigation of patients with biliary acute pancreatitis. (+info)
Manometry based randomised trial of endoscopic sphincterotomy for sphincter of Oddi dysfunction.
(3/201)
BACKGROUND: Endoscopic sphincterotomy for biliary-type pain after cholecystectomy remains controversial despite evidence of efficacy in some patients with a high sphincter of Oddi (SO) basal pressure (SO stenosis). AIM: To evaluate the effects of sphincterotomy in patients randomised on the basis of results from endoscopic biliary manometry. METHODS: Endoscopic biliary manometry was performed in 81 patients with biliary-type pain after cholecystectomy who had a dilated bile duct on retrograde cholangiography, transient increases in liver enzymes after episodes of pain, or positive responses to challenge with morphine/neostigmine. The manometric record was categorised as SO stenosis, SO dyskinesia, or normal, after which the patient was randomised in each category to sphincterotomy or to a sham procedure in a prospective double blind study. Symptoms were assessed at intervals of three months for 24 months by an independent observer, and the effects of sphincterotomy on sphincter function were monitored by repeat manometry after three and 24 months. RESULTS: In the SO stenosis group, symptoms improved in 11 of 13 patients treated by sphincterotomy and in five of 13 subjected to a sham procedure (p = 0.041). When manometric records were categorised as dyskinesia or normal, results from sphincterotomy and sham procedures did not differ. Complications were rare, but included mild pancreatitis in seven patients (14 episodes) and a collection in the right upper quadrant, presumably related to a minor perforation. At three months, the endoscopic incision was extended in 19 patients because of manometric evidence of incomplete division of the sphincter. CONCLUSION: In patients with presumed SO dysfunction, endoscopic sphincterotomy is helpful in those with manometric features of SO stenosis. (+info)
Clinical features and management of biliary ascariasis in a non-endemic area.
(4/201)
Biliary ascariasis is common in certain geographical areas of the world. In India, it is common in the Kashmir valley and only stray cases have been reported from other parts of the country. Between January 1995 and May 1997, 14 patients with biliary ascariasis were seen at our centre, which is more than 1000 km from the Kashmir valley. The mean (+/- SD) age of the patients was 31.7 (+/- 6.1) years and all were females. None of them had been to a place known to be endemic for biliary ascariasis. Four patients presented with acute cholangitis, eight with acute abdominal pain and vomiting, and the remaining two were diagnosed incidentally during surgery for gallstone disease. Barring these two patients, ultrasound examination of the abdomen diagnosed the condition accurately. In 10 patients, a part of the worm was visible outside the papilla of Vater. The roundworm was caught in a Dormia basket and could be extracted in nine patients. In one patient the worm migrated inside the bile duct while it was being caught in a Dormia basket. In this and two other patients, in whom the worm had migrated completely inside the bile duct, worms were removed with the help of a Dormia basket after endoscopic sphincterotomy. There were no complications of endoscopic therapy. In the two patients in whom biliary ascariasis was detected during surgery, the worms were removed after choledocholithotomy. On a mean follow-up of 13.8 months, only one patient had a recurrence of biliary ascariasis. It is concluded that biliary ascariasis is not an uncommon disease and must be considered as a possibility in patients presenting with acute cholangitis and biliary pain even in a non-endemic area. Ultrasonography is an excellent diagnostic tool and endoscopic management is very effective and safe in the treatment of these patients. (+info)
Preoperative versus postoperative endoscopic retrograde cholangiopancreatography in mild to moderate gallstone pancreatitis: a prospective randomized trial.
(5/201)
OBJECTIVE: To determine whether endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct (CBD) stone extraction should be performed routinely before surgery or'selectively after surgery in patients with mild to moderate gallstone pancreatitis. SUMMARY BACKGROUND DATA: The role and timing of ERCP in mild to moderate gallstone pancreatitis remains controversial. Routine preoperative ERCP identifies persisting CBD stones but carries risks of complications and may delay definitive care. Selective postoperative ERCP, performed only if a CBD stone is seen on intraoperative cholangiography (IOC), avoids unnecessary ERCP but risks unsuccessful stone extraction. METHODS: A prospective, randomized study of consecutive patients with gallstone pancreatitis was conducted. Using previously determined criteria, patients with acute cholangitis or necrotizing pancreatitis were excluded. Patients considered at high risk for persisting CBD stones (CBD size > or =8 mm on admission ultrasound, serum total bilirubin > or = 1.7 mg/dL, or serum amylase > or = 150 U/L on hospital day 4) were randomly assigned to routine preoperative ERCP followed by laparoscopic cholecystectomy, or laparoscopic cholecystectomy with selective postoperative ERCP and endoscopic sphincterotomy only if a CBD stone was present on IOC. Primary end points were costs, length of hospital stay, and the combined treatment failure rates (failure of diagnostic ERCP and IOC, complications of ERCP and endoscopic sphincterotomy, and complications of surgery). RESULTS: One hundred fifty-four consecutive patients with gallstone pancreatitis were evaluated prospectively for study eligibility. Sixty patients met the randomization criteria. Thirty patients were randomized to routine preoperative ERCP and 29 patients to selective postoperative ERCP (1 patient refused). Age, admission laboratory values, and APACHE II and Imrie scores were similar in both groups. By protocol, ERCP was performed in all patients in the preoperative ERCP group. In the postoperative ERCP group, ERCP was necessary in only 7 of 29 patients (24%). Mean hospital stay was significantly longer in the routine preoperative ERCP group (11.7 days) than in the selective postoperative ERCP group (9.0 days). Mean total cost was higher in the preoperative ERCP group ($9,426) than in the postoperative ERCP group ($7,798). The combined treatment failure rate was 10% in both groups. CONCLUSIONS: In patients with mild to moderate gallstone pancreatitis without cholangitis, selective postoperative ERCP and CBD stone extraction is associated with a shorter hospital stay, less cost, no increase in combined treatment failure rate, and significant reduction in ERCP use compared with routine preoperative ERCP.

Management of duodenal perforation after endoscopic retrograde cholangiopancreatography and sphincterotomy.
(6/201)
OBJECTIVE: To evaluate the authors' experience with periduodenal perforations to define a systematic management approach. SUMMARY BACKGROUND DATA: Traditionally, traumatic and atraumatic duodenal perforations have been managed surgically; however, in the last decade, management has shifted toward a more selective approach. Some authors advocate routine nonsurgical management, but the reported death rate of medical treatment failures is almost 50%. Others advocate mandatory surgical exploration. Those who favor a selective approach have not elaborated distinct management guidelines. METHODS: A retrospective chart review at the authors' medical center from June 1993 to June 1998 identified 14 instances of periduodenal perforation related to endoscopic retrograde cholangiopancreatography (ERCP), a rate of 1.0%. Charts were reviewed for the following parameters: ERCP findings, clinical presentation of perforation, diagnostic methods, time to diagnosis, radiographic extent and location of duodenal leak, methods of management, surgical procedures, complications, length of stay, and outcome. RESULTS: Fourteen patients had a periduodenal perforation. Eight patients were initially managed conservatively. Five of the eight patients recovered without incident. Three patients failed nonsurgical management and required extensive procedures with long hospital stays and one death. Six patients were managed initially by surgery, with one death. Each injury was evaluated for location and radiographic extent of leak and classified into types I through IV. CONCLUSIONS: Clinical and radiographic features of ERCP-related periduodenal perforations can be used to stratify patients into surgical or nonsurgical cohorts. A selective management scheme is proposed based on the features of each type. (+info)
Extrahepatic biliary obstruction due to post-laparoscopic cholecystectomy biloma.
(7/201)
BACKGROUND: Jaundice presenting after cholecystectomy may be the initial manifestation of a serious surgical misadventure and requires rigorous diagnostic pursuit and therapeutic intervention. Biloma is a well recognized postcholecystectomy complication that often accompanies biliary ductal injury. CASE REPORT: A 23-year-old female underwent laparoscopic cholecystectomy for symptomatic gallstones and three weeks postoperatively developed painless jaundice. Radiographic and endoscopic studies revealed a subhepatic biloma causing extrinsic compression and obstruction of the common hepatic duct. RESULTS: Percutaneous catheter drainage of the biloma combined with endoscopic sphincterotomy successfully relieved the extrahepatic biliary obstruction and resolved the intrahepatic ductal leak responsible for the biloma. CONCLUSION: Although heretofore undescribed, postcholecystectomy jaundice due to extrahepatic bile duct obstruction caused by biloma may occur and can be successfully treated by means of standard radiologic and endoscopic interventions.

Endoscopic injection of botulinum toxin in patients with recurrent acute pancreatitis due to pancreatic sphincter of Oddi dysfunction.
(8/201)
AIM: To evaluate the technical feasibility, safety, and short-term efficacy of botulinum toxin injection for pancreatic sphincter of Oddi dysfunction and to analyse whether the symptomatic response to botulinum toxin might be a predictor of outcome for endoscopic sphincterotomy. METHODS: Fifteen consecutive patients (nine female, aged 38 +/- 12 years) with frequent attacks (median four) of acute pancreatitis within 6 months, and manometrically proven pancreatic sphincter of Oddi dysfunction underwent endoscopic injection of 100 units of botulinum toxin into the major papilla. All patients underwent prospective follow-up thereafter and in cases of recurrent pancreatitis manometry this was repeated and pancreatic sphincterotomy was performed. RESULTS: No side-effects occurred after botulinum toxin injection in any patient. Within 3 months after botulinum toxin treatment, 12 out of 15 patients remained asymptomatic (80% primary response). Only one out of three patients without symptomatic benefit showed continued elevated pancreatic sphincter pressure at manometry and only this patient benefited from pancreatic sphincterotomy later on. Eleven of the 12 patients initially responding to botulinum toxin injection developed a symptomatic relapse 6 +/- 2 months after botulinum toxin treatment. These patients then achieved long-term clinical remission from pancreatic or combined (biliary and pancreatic, n=5) sphincterotomy (median follow-up, 15 months). CONCLUSION: Endoscopic botulinum toxin injection into the papilla of Vater is a safe procedure for treatment of pancreatic sphincter of Oddi dysfunction that may provide short-term relief in about 80% of the patients. Those patients who respond to botulinum toxin may subsequently gain definitive cure from sphincterotomy. (+info)
