Randomized clinical trial of intraoperative endoscopic retrograde cholangiopancreatography versus laparoscopic bile duct exploration in patients with choledocholithiasis.

BACKGROUND: Various minimally invasive approaches exist for the management of choledocholithiasis at the time of laparoscopic cholecystectomy. The aim of this study was to compare endoscopic retrograde cholangiopancreatography (ERCP) with laparoscopic bile duct exploration (LBDE) and test the hypothesis that intraoperative ERCP is no different to LBDE in terms of rate of bile duct clearance or retained stones. METHODS: Eligible patients with choledocholithiasis undergoing emergency laparoscopic cholecystectomy were randomized to intraoperative ERCP or LBDE in a 1 : 1 ratio. The primary outcomes were rates of bile duct clearance and retained stones. Secondary outcomes were postprocedure complication rate, mortality rate, postoperative length of hospital stay, conversion to open surgery rate, procedural time and total duration of surgery. RESULTS: Some 104 patients were randomized, and 52 patients in each group were included in an intention-to-treat analysis. Duct clearance rates were 87 per cent for patients who had intraoperative ERCP and 69 per cent for those in the LBDE group (P = 0·057). The rate of retained stones was lower in the ERCP group than in the LBDE group: 15 versus 42 per cent respectively (P = 0·004). Median postoperative length of stay was shorter with ERCP (2 days versus 3 days for LBDE; P = 0·015). CONCLUSION: Intraoperative ERCP is more effective than LBDE in terms of minimizing the rate of retained stones in patients with choledocholithiasis undergoing emergency laparoscopic cholecystectomy.

Clinical selection criteria can predict futile intervention in patients referred for percutaneous endoscopic gastrostomy insertion.

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) placement is performed in a patient group with high mortality in the short and medium term. For a significant proportion of patients, the procedure provides no increase in survival. There are no standardised assessment tools available to determine the clinical appropriateness of PEG placement, nor any to predict clinical outcome. AIM: The study aims to determine whether clinical assessment, by a trained dietitian, of the appropriateness of PEG placement is predictive of mortality in the short and medium terms. METHODS: A prospective audit was undertaken of all requests for PEG placement at a single large, publicly funded Australian tertiary hospital. The clinical appropriateness of each request was assessed by a trained dietitian, and data on age, sex, reason for referral, comorbidities and satisfaction of assessment criteria were collected, and patient outcome and survival were compared for all patients according to whether a PEG was inserted or not. Main outcome measures were mortality at 30 and 150 days after referral. RESULTS: During the period 2005-2008, 198 patients were referred for PEG; 94 were assessed as appropriate referrals, 104 as inappropriate. Eighty-four patients who underwent gastrostomy, after being assessed as appropriate, had significantly reduced mortality at 30 days (96.4% vs 74.6%, P < 0.0001) and 150 days (82.1% vs 57.9%, P = 0.0001) compared with all other patients. Patients who received PEG despite contrary advice had no significant survival advantage, at 30 days or 150 days, over patients who did not receive PEG. CONCLUSION: The application of selection criteria by trained assessors improves patient selection for PEG insertion and predicts mortality at early and later time points, by identifying patients unlikely to benefit from PEG. The group of patients who received a gastrostomy despite an adverse assessment had no mortality benefit - in these patients, the procedure may have been futile.

Recurrent pancreatitis in a child with pancreas divisum. Endoscopic therapy of a Santorinicele.

Pancreas divisum is a rare congenital anomaly of the pancreatic ducts that has been implicated in pancreatitis. In addition, the finding of a Santorinicele, which is a cystic dilatation of the dorsal duct, suggests that there is an obstruction associated with a congenital or acquired weakness of the mucosa. We used an endoscopic technique to treat a child with recurrent pancreatitis who was found to have pancreas divisum and a large Santorinicele.
