Evaluation of Risk Factors Leading to Conversion From Laparoscopic Cholecystectomy to Open Surgery

This retrospective controlled study aims to evaluate risk factors that affect open conversion in laparoscopic cholecystectomy. Patient characteristics, medical history, biochemical and radiological studies of the patient will searched from the hospital database and factors affecting open conversion will be analysed.

Cholecystectomy is a commonly performed procedure in general surgical practice, and with advancements in technology, it is widely conducted using the laparoscopic method. Despite the decreasing trend in open surgical procedures with increasing experience and technological developments, the literature reports conversion to open surgery in laparoscopic cholecystectomy ranging from 2% to 15%. Although some studies exist regarding patient groups at risk of conversion to open surgery, the current literature is insufficient to draw a clear conclusion on this matter. This study aims to evaluate risk factors for conversion to open surgery by examining cases of laparoscopically initiated cholecystectomy. The study will be conducted retrospectively by reviewing archive records. Patients operated for cholecystectomy will be included. Patients that open surgical method used from start will be excluded from study. Age, comorbidities (ASA score), laboratory findings (leukocyte count and CRP), imaging findings (abdominal ultrasound, CT, or MRI), history of previous abdominal surgery, history of ERCP, and history of pancreatitis will be evaluated. Laparoscopic cholecystectomy cases will be compared with open-conversion cholecystectomies to assess factors influencing the conversion.
