    ABSTRACT: Background/aims: The objective of this study was to define the clinical, biochemical and ultrasonographic criteria correlating with a likelihood of a positive preoperative endoscopic ultrasound (EUS) in patients presenting with acute gallstone-related pancreatobiliary disease. Methodology: All patients who underwent EUS prior to elective laparoscopic cholecystectomy were analyzed at the Gastroenterology Unit, Kaplan Medical Center, following acute admission with cholecystitis, cholelithiasis, cholangitis, acute pancreatitis and obstructive jaundice. Results: One hundred and seventy four patients met the inclusion criteria. EUS showed choledocholithiasis in 37 (21.3%) with 35/37 undergoing a preoperative ERCP (24/35 cases - 64.9% positive yield). Twenty seven of the positive EUS studies (73%) were performed during the acute illness, with 50 of the 137 negative studies (36.4%) performed during the acute phase of the illness (p=0.0001). On multivariate analysis, a positive EUS was more commonly found during the acute phase of the illness [OR: 3.445; 95% CI: 1.48-8.008, p=0.004] or if there was transient jaundice [OR: 1.167; 95% CI: 1.002-1.36, p=0.047]. Conclusions: The timing of the examination influences the detection rate of CBD stones by EUS prior to surgery although it may be appropriate to more selectively use EUS in those patients with hyperbilirubinaemia and/or where the CBD is dilated.

    ABSTRACT: Opiate or benzodiazepine drugs are often used during colonoscopy, but they are associated with respiratory depression and prolonged recovery. Physostigmine, a tertiary anticholinesterase agent, is known to enhance analgesia and to reverse the central nervous system depressant effects of these drugs. This study compared the effect of giving meperidine alone with the effect of giving meperidine in combination with physostigmine in patients who were undergoing complete colonoscopy. A total of 44 outpatients undergoing elective colonoscopy were randomly assigned to receive analgesia with either meperidine 0.5 mg/kg intravenously (group 1, n=24) or physostigmine 10 micrograms/kg intravenously, followed 5 minutes later by meperidine 0.5 mg/kg intravenously (group 2; n=20). The patients were assessed with regard to oxygen saturation, hemodynamic changes, pain perception and sedation scores, readiness to go home, and adverse effects. The group 1 patients' oxygen saturations consistently fell, both during the procedure and in the recovery period; in group 2, oxygen saturations remained stable throughout the procedure and recovery period (95.88%+/-0.99 vs. 98.15+/-0.99, P<0.001). Patients in group 2 reported lower pain perception scores during the procedure (measured using a visual analog scale) than patients in group 1 (1.46+/-0.31 vs. 1.75+/-0.41; F1,42=6.484, P<0.015) and were less sedated during recovery (F1,41=6.56, P<0.015). No significant differences were found between the two groups with regard to heart rate or arterial blood pressure. All patients in group 2 were ready to go home after 25 minutes in the recovery area; three patients in group 1 were not ready to leave at 25 minutes and left the facility after 60 minutes. Four patients suffered from minor side effects of physostigmine (sweating and nausea). Combining physostigmine with meperidine as preparatory treatment for patients undergoing colonoscopy prevents respiratory depression, improves analgesia, and shortens recovery time, with only mild side effects.
