'Single-Sitting' Laparoscopic Cholecystectomy and Endoscopic Removal of Common Bile Duct Stone for Cholelithiasis and Choledocholithiasis: a Feasibility Study.

'Single-sitting' laparoscopic cholecystectomy followed by endoscopic common bile duct clearance is emerging as a viable option for management of cholelithiasis and concomitant choledocholithiasis. The only disadvantage of the procedure is logistical since it requires co-ordination between two teams-the surgeons and the endoscopists. This limitation can be overcome in centres where both the procedures are performed by one team. With a considerable experience in endoscopy, we conducted a prospective study in a select group of patients to assess the feasibility of this single-sitting approach. The study included 38 patients with a radiological diagnosis of choledocholithiasis or jaundice at presentation. After laparoscopic cholecystectomy, the patients were turned prone and subjected to endoscopic retrograde cholangiogram, sphincterotomy and extraction of the common bile duct stone. The procedure was successful in 33 (87 %) of patients. The mean procedure time and hospital stay were 2 h, 20 min and 2 days, respectively. None of the patients had any major complications. We conclude that in a select group of patients, single-sitting laparoscopic cholecystectomy followed by endoscopic clearance of the common bile duct stone is safe and effective.

A rare presentation of mass abdomen.

An elderly male who had undergone inguinal hernia surgery eight years back presented with an intra-abdominal mass. Clinically and radiologically it was diagnosed as mesenteric cyst. Laparotomy revealed a thick walled cyst embedded in the omentum, containing brownish necrotic material and few 'linen thread knots'. On the basis of the latter finding the mass was thought to be a walled off hematoma, a complication of previous hernia surgery. Such a complication of inguinal surgery has not been reported earlier.

Biliary ascariasis--role of endoscopic intervention.

AIM: This study was undertaken to review the predisposing factors, presentation and management of patients diagnosed with biliary ascariasis while specifically emphasizing the role played by endoscopy. METHODS: We performed a retrospective analysis of nine patients diagnosed and admitted with biliary ascariasis at our center. The diagnosis was based on ultrasound findings and confirmed by detection of round worms in the biliary tract or the descending duodenum. The clinical presentation and management were reviewed. RESULTS: Five of the nine patients had prior biliary sphincter ablative/bypass procedures for choledocholithiasis; including endoscopic sphincterotomy in four and lateral choledochoduodenostomy in one patient. All but one patient presented with acute onset pain abdomen radiating to the back. One patient presented with features of acute cholecystitis. Ultrasound detected the presence of round worms in all the patients. Endoscopic retrograde cholangio-pancreatogram confirmed presence of worm in the biliary tree. Endoscopic extraction of the worm from the biliary tree or duodenum was successfully undertaken in all the patients and provided prompt relief. One patient had recurrence of infection after eight months which was re-treated by endoscopic extraction. Antihelminthics were instituted in all patients. CONCLUSION: Biliary ascariasis, should be considered in the differential diagnosis of acute abdomen, particularly in patients who have undergone prior biliary sphincter ablation/bypass procedures like sphincterotomy or choledochoduodenostomy. Ultrasonography is a reliable diagnostic modality. Endoscopic retrograde cholangiogram confirms the diagnosis and precedes endoscopic extraction of the worm. This offers prompt relief from symptoms.
