A delayed conversion may increase the risk of major complications in acute cholecystitis approached laparoscopically. A retrospective comparative cohort study.

Aim: Aim of this study was to evaluate whether timing of laparoscopy lasting longer than two hours before converting to open surgery can worsen the postoperative course during laparoscopic cholecystectomy (LC) for acute cholecystitis (AC).

Materials And Methods: Medical records of 1,161 patients who underwent urgent laparoscopic cholecystectomy for AC during the period 2001-2017 were retrospectively analyzed. A conversion to open surgery was performed in 70 (6%) patients.

Incidental appendectomy? Microscopy tells another story: A retrospective cohort study in patients presenting acute right lower quadrant abdominal pain.

Background: Optimal management of macroscopically normal appendix encountered during laparoscopy for acute abdominal pain is still unclear.

Methods: 164 acute abdominal pain cases in which laparoscopy showed a normal appendix were reviewed. No other intra-peritoneal acute disease was present in 50 patients (Group 1) whereas a miscellanea of intra-peritoneal conditions was identified in the other 114 (Group 2).
