Parameters for safe dissection at Calot's Triangle in Laparoscopic Cholecystectomy

Abstract

Objective: To explore the parameters critical to safe laparoscopic cholecystectomies.
Method: The prospective study was conducted at Al-Yarmook Teaching Hospital, Baghdad, from May 1, 2020, to
December 31, 2021, and comprised patients with gall-stone disease who were admitted for laparoscopic
cholecystectomy. Consecutive non-probability sampling technique was used for collecting the data which was
analysed using SPSS (version 25).
Results: Of the 93 patients, 68(73.12%) were females, and 25(26.88) were males. The overall mean age was 40.7±8.1
years, and 52(55.91%) patients were aged >40 years. Calot triangle was seen in 72(77.4%) cases, while the sulcus of
Rouviere, duodenum and right hepatic artery were spotted in 50(53.8%), 49(52.7%) and 19(20.4%) cases,
respectively. There was a significant association of late presentation, lateral traction, 4-port option, good setting and
difficult anatomy with anatomical landmark visualisation (p<0.05).
Conclusions: There is a need for a national guideline to ensure safe laparoscopic cholecystectomy.
