Predictive factors for conversion to open surgery in patients undergoing elective laparoscopic cholecystectomy

Area of Science:

• Surgical Gastroenterology
• Minimally Invasive Surgery
• Biliary Tract Surgery

Background:

• Laparoscopic cholecystectomy (LC) is the standard for symptomatic gallbladder disease.
• Identifying predictors for conversion to laparotomy is essential for patient safety and surgical training.

Purpose of the Study:

• To identify factors predicting conversion from LC to open surgery.
• To improve patient selection and surgical decision-making during LC.

Main Methods:

• Prospective analysis of 2015 patients undergoing elective LC (2002-2007).
• Comparison of successfully completed LC cases (n=1914) versus converted cases (n=101).
• Multivariate logistic regression analysis of demographics, lab values, imaging, and intraoperative findings.

Main Results:

• 5.0% of patients required conversion to open cholecystectomy.
• Univariate analysis identified age, male gender, prior surgery, elevated WBC, liver enzymes, thickened gallbladder wall, dilated CBD, ERCP, adhesions, and gallbladder appearance as predictors.
• Multivariate analysis confirmed previous abdominal surgery, preoperative ERCP, high-grade adhesions, and scleroatrophic gallbladder appearance as significant predictors of conversion.

Conclusions:

• Patient selection is critical for safe and efficient LC training.
• Established predictive factors can guide surgeons in deciding when to convert LC to open surgery.
