An increased incidence of cholelithiasis has been widely reported after truncal vagotomy and after gastric resection. In the early phase of patient selection, previous gastrectomy has been considered a relative contraindication to laparoscopic cholecystectomy (LC). In this study, we examined the management of LC in patients with previous gastrectomy. ⋯ Clear visualization of anatomic structures and landmarks, and scrupulous hemostasis are needed to perform a safe LC in these patients. We conclude that in our study patients, a previous gastrectomy is considered an indication for LC and laparoscopic choledochotomy.

The use of advanced technology, such as virtual environments and computer-based simulators (VR/CBS), in training has been well established by both industry and the military. In contrast the medical profession, including surgery, has been slow to incorporate such technology in its training. In an attempt to identify factors limiting the regular incorporation of this technology into surgical training programs, a survey was developed and distributed to all general surgery program directors in the United States. ⋯ Virtual environments and computer-based simulators, although well established training tools in other fields, have not been widely incorporated into surgical education. Our results suggest that program directors believe this type of technology would be beneficial in surgical education, but they lack adequate information regarding VR/CBS. Developers of this technology may need to focus on educating potential users and addressing their concerns.

Evaluation of peritoneal cytology provides valuable staging information in patients with gastric and pancreatic adenocarcinoma, but its usefulness in patients with extrahepatic cholangiocarcinoma is unclear. The aim of this study was to evaluate the predictive value of peritoneal cytology in patients with potentially resectable hilar cholangiocarcinoma. This study evaluated a possible association between positive peritoneal cytology and percutaneous transhepatic biliary drainage, which is commonly used in these patients and may result in peritoneal biliary leakage and peritoneal seeding. ⋯ Peritoneal cytology was not predictive of occult metastatic disease. Laparoscopic staging identified some patients with unresectable hilar cholangiocarcinoma, but analysis of peritoneal cytology provided no additional information. There was no association between percutaneous transhepatic biliary drainage and peritoneal tumor seeding.
