Laparoscopic cholecystectomy (LC) has supplanted open cholecystectomy for most gallbladder pathology. Experience has allowed the development of now well-established technical nuances, and training has raised the level of performance so that safe LC is possible. If safe cholecystectomy cannot be performed because of acute inflammation, LC tube placement should occur. A systematic approach in every case to open a window beyond the triangle of Calot, well up onto the liver bed, is essential for the safe completion of the operation.

Mucinous neoplasms of the appendix were found in 5 of 17 patients (29.4%) undergoing interval appendectomy. Interval appendectomies should be considered in all adult patients, especially those 40 years or older, to determine the underlying cause of appendicitis. A multi-institutional study to determine the generalizability of these findings is warranted.

Risk-group targeted prophylactic inferior vena cava filter placement prior to RYGB is safe with a trend towards reduced occurrence of PE.
