Management of duodenal perforation after endoscopic retrograde cholangiopancreatography and sphincterotomy. (25/1054)

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)

Diagnosis and management of acute pancreatitis. (26/1054)

Acute pancreatitis usually occurs as a result of alcohol abuse or bile duct obstruction. A careful review of the patient's history and appropriate laboratory studies can help the physician identify the etiology of the condition and guide management. Serum amylase and lipase levels are still used to confirm the diagnosis of acute pancreatitis. Although not routinely available, the serum trypsin level is the most accurate laboratory indicator for pancreatitis. Ultrasonography, computed tomography and endoscopic retrograde cholangiopancreatography are additional modalities that can help the family physician choose the best treatment approach. Prompt identification of patients who need intensive care referral or subspecialty consultation is crucial. The APACHE II and the multiple organ system failure scales provide prognostic information at the time of admission and may be repeated daily to monitor disease progression. Therapies such as nasogastric suctioning, anticholinergics and histamine H2-receptor blockers have not been shown to decrease symptoms or hospital stays in patients with acute pancreatitis. Systemic antibiotics have been found to improve outcome in patients with severe disease. With supportive care, most patients have a good clinical outcome.  (+info)

The efficacy of preoperative endoscopic retrograde cholangiopancreatography in the detection and clearance of choledocholithiasis. (27/1054)

BACKGROUND AND OBJECTIVES: Endoscopic retrograde cholangiopancreaticography has been reported to have a high success rate in the detection and treatment of choledocholithiasis. Although there is growing enthusiasm for laparoscopic common bile duct clearance, many patients who present with gallbladder disease and suspected choledocholithiasis have endoscopic retrograde cholangiopancreatography performed with choledocholithiasis cleared if detected. These patients are then referred for laparoscopic cholecystectomy. The purpose of this study is to determine the efficacy of preoperative endoscopic retrograde cholangiopancreatography in the diagnosis and clearance of bile duct stones at our institution. METHODS: A retrospective review was performed of all patients at this institution who underwent preoperative endoscopic retrograde cholangiopancreatography for suspected choledocholithiasis followed by laparoscopic cholecystectomy from January 1997 through July 1998. RESULTS: Common bile duct stones were detected endoscopically in 12 of 17 (71%) patients. We found serum bilirubin level to be the best predictor of choledocholithiasis. In 12 of 12 procedures, the endoscopist performed an endoscopic sphincterotomy with stone extraction and reported a fully cleared common bile duct. Intraoperative cholangiogram performed during subsequent cholecystectomy revealed choledocholithiasis in 4 of these 12 patients. Laparoscopic techniques successfully cleared the choledocholithiasis in 3 of these patients with open techniques necessary in the fourth. CONCLUSIONS: Our data suggests that even after presumed successful endoscopic clearance of the bile duct stones, many patients (33% in our series) still have choledocholithiasis present at the time of cholecystectomy. We recommend intraoperative cholangiography at the time of cholecystectomy even after presumed successful endoscopic retrograde cholangiopancreatography with further intervention, preferably laparoscopic, to clear the choledocholithiasis as deemed necessary.  (+info)

Repair of common bile duct injury with the round and falciform ligament after clip necrosis: case report. (28/1054)

Occasionally, as abdominal surgeons, we are confronted with common bile duct injury noted during video laparoscopic or open cholecystectomy. Usually this is solved by endoscopic retrograde cholangiopancreatography (ERCP) sphincterotomy and stent, or enteric bypass, suture repair and tube drainage. However, after such procedures, there is a significant number of patients with postoperative stenosis. Another alternative to repair common bile duct injury and correct postoperative stenosis is using the round and falciform ligament as circumferencial patch. Due to their closeness to the common bile duct and their adequate blood supply, they make a perfect autologous biological graft.  (+info)

Extrahepatic biliary obstruction due to post-laparoscopic cholecystectomy biloma. (29/1054)

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.  (+info)

Sedation with propofol plus midazolam versus propofol alone for interventional endoscopic procedures: a prospective, randomized study. (30/1054)

AIM: Adequate patient sedation is mandatory for most interventional endoscopic procedures. Recent anaesthesiologic studies indicates that propofol and midazolam act synergistically in combination and therefore may be superior to sedation with propofol alone in terms of sedation efficacy, recovery and costs (due to a presumed lower total dose of propofol needed). METHODS: A total of 239 consecutive patients undergoing therapeutic EGD or ERCP (EGD/ERCP-ratio, 1:1) randomly received either propofol alone (n=120, group A, loading dose 40-60 mg intravenously, followed by repeated doses of 20 mg) or propofol plus midazolam (n=119, group B, initial midazolam dose of 2. 5-3.5 mg intravenously, followed by repeated doses of 20 mg of propofol) for sedation. Vital signs (heart rate, blood pressure, oxygen saturation, electrocardiogram) were continuously monitored. Procedure-related parameters, the recovery time and quality (post-anaesthesia recovery score) as well as the patient's co-operation and tolerance to the procedure (visual analogue scale) were prospectively assessed. RESULTS: Patients of group A and B were well matched with respect to demographic and clinical data, endoscopic findings, and the type of associated procedures. In group A, a mean dose of 0.25 +/- 0.13 mg.min/kg propofol was used compared to 0.20 +/- 0.09 mg.min/kg of propofol in group B (P < 0.01, plus additional 2.9 +/- 0.5 mg of midazolam). Clinically relevant changes in vital signs were observed at comparable frequencies with a lowering of the systolic blood pressure < 90 mmHg in six out of 119 patients in group B and one out of 120 patients in group A (P=0.07). The sedation efficacy was rated similarly in both groups, whereas the mean recovery time (group A, 19 +/- 7 min vs. group B, 25 +/- 8 min, P < 0.05) as well as the recovery score (post-anaesthesia recovery score group A, 8.0 +/- 1.1 vs. post-anaesthesia recovery score group B, 7.3 +/- 1.2, P < 0.001) were significantly better with propofol alone than with propofol plus midazolam. CONCLUSION: During therapeutic endoscopy, sedation with propofol and midazolam requires a lower total dose of propofol, but otherwise has no superior sedation efficacy and is associated with a slower post-procedure recovery than sedation with propofol alone.  (+info)

Common anxieties of patients undergoing oesophago-gastro-duodenoscopy, colonoscopy and endoscopic retrograde cholangio-pancreatography. (31/1054)

AIMS & METHODS: To investigate the anxieties of patients undergoing oesophago-gastro-duodenoscopy (OGD), colonoscopy and endoscopic retrograde cholangio-pancreatography (ERCP) in relation to their demographic features, their knowledge and understanding of the procedure, its indication, and their doctors' explanation. A standard questionnaire was filled in consecutively for 280 OGD patients, 64 colonoscopy patients and 50 ERCP patients. RESULTS & CONCLUSIONS: Majority of the anxious patients were afraid of pain. There was no difference between the "fearless" and "fearful" groups in terms of source of referral and inpatient/outpatient status. However for all 3 procedures, anxious patients were significantly younger by a mean of 10 years. Females, better educated and OGD patients undergoing the procedure for the first time were more anxious but this difference was not seen with the more complex colonoscopy and ERCP. The more sophisticated ERCP seemed to instill greater anxiety amongst Malay patients. Doctors were significantly more likely to explain the indication for OGD and colonoscopy than how it would be done. This discrepancy was not seen with ERCP where the endoscopists tend to adopt a more personal approach. Most patients prefer to be sedated.  (+info)

Characteristics of acute pancreatitis in University Kebangsaan Malaysia. (32/1054)

We analyzed the characteristics of patients presenting with acute pancreatitis to our unit. A total of 71 patients were admitted to the Surgical Department at University Kebangsaan Malaysia (UKM) over a period of seven years, between January 1990 to December 1996 with acute pancreatitis. There was a fourfold increase in incidence of acute pancreatitis in our hospital from January 1990 to December 1996. The commonest identifiable aetiology was gallstones followed by alcohol. There were two deaths. We conclude that acute pancreatitis is increasingly being diagnosed in our local population. This may be due to either greater awareness or changes in lifestyle of the population.  (+info)
