Randomized Controlled Trial Comparative Study Clinical Trial
Controlled clinical trial comparing early with interval cholecystectomy for acute cholecystitis.
The traditional management of acute cholecystitis is initial conservative treatment with antibiotics followed by elective cholecystectomy. Although early cholecystectomy has often been advocated, there has been only one randomized controlled clinical trial comparing the two methods of treatment. This paper reports the preliminary results of such a trial in which 32 patients have been studied so far. ⋯ The incidence of minor postoperative complications was only slightly greater in those treated by early operation. The length of postoperative stay was similar in both groups but those treated conservatively spent an average of 11 more days in hospital. The preliminary results indicate that those treated by early cholecystectomy spend less time in hospital and avoid the complications of failed conservative treatment without the added risk of increased postoperative mortality and major complications.

This study has investigated the relationship between duodenogastric reflux, gastritis and certain symptoms 6-12 months after three operations for uncomplicated duodenal ulcer. The operations studied were proximal gastric vagotomy (PGV, 20 cases), truncal vagotomy and pyloroplasty (TV+P, 22 cases) and truncal vagotomy and antrectomy (TV+A, 21 cases). Duodenogastric reflux was assessed both by a radiological technique and by measuring the concentration of bilirubin in the gastric aspirate before and after operation. ⋯ The amount of reflux did not differ before operation. There was significantly less reflux following PGV than after either TV+P (P less than 0-025) or TV+A (P less than 0-001). The results indicate that an operation which preserves an innervated and intact antrum and pylorus will protect against postoperative duodenogastric reflux, gastritis and symptoms.
