265 Group and Saves for Laparoscopic Cholecystectomies: An Unnecessary Expense?

Video Summarization of Laparoscopic Cholecystectomies

We compared image features with a distance metric and support vector machine to identify the critical view of a laparoscopic cholecystectomy. Our accuracy was up to 91%. We are currently experimenting with particle analysis, edge analysis, and feature clustering to create a more robust image classifier.

Difficult Cholecystectomies: Validity of the Laparoscopic Approach

OBJECTIVES The aim of this work was to determine the outcome of "difficult cholecystectomy" caused by acute cholecystitis or cirrhosis, in relation to the number of conversions, principal biliary duct injuries, the length of the operation, and of postoperative hospitalization. METHODS From 1998 through 2000, 51 patients, 38 females and 13 males, underwent cholecystectomy for acute cholecystit...

The preoperative evaluation: medical necessity or unnecessary expense?

Laryngeal mask airway protector™: Advanced uses for laparoscopic cholecystectomies

The laryngeal mask airway (LMA) Protector™ is a second-generation perilaryngeal sealer type supraglottic airway device recently introduced into clinical practice. We describe our initial experiences with the use of the LMA Protector™ in three patients undergoing laparoscopic cholecystectomies. In all patients, we found the LMA Protector™ to have acceptable placements on the first attempt, adequ...

Feasibility of robot-assisted laparoscopic surgery: an evaluation of 35 robot-assisted laparoscopic cholecystectomies.

Laparoscopic surgery offers patients distinct benefits but is not without its disadvantages to surgeons in terms of maneuverability and visualization. Robotic telemanipulation systems were introduced with the objective of providing a solution to the problems in this field of surgery. The feasibility of robot-assisted surgery was assessed by performing 35 laparoscopic cholecystectomies with the ...
