Implementation of new procedures, including lymphatic mapping for breast cancer, must be done and overseen by the medical community in a responsible way to ensure that the procedures are performed correctly. This study addresses the issues of adequacy of training and certification of surgeons performing lymphatic mapping. Ensuring quality in surgical care requires outcomes measures that are described in this study. ⋯ This experience defines a learning curve for lymphatic mapping in breast cancer patients. Data suggest that increased volumes lead to decreased failure rates. These data provide surgeons performing SLN biopsy with a new paradigm for assessing their skill and adequacy of training and describes the relationship between volume of cases performed and success rate of SLN detection.

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.

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.
