Laparoscopic cholecystectomy in obese patients

Area of Science:

• Surgical Gastroenterology
• Minimally Invasive Surgery
• Bariatric Surgery Outcomes

Background:

• Laparoscopic cholecystectomy (LC) is the standard surgical treatment for symptomatic gallstones.
• Historically, obesity was a contraindication for LC due to perceived increased risks.
• This study investigates the impact of Body Mass Index (BMI) on LC outcomes.

Purpose of the Study:

• To evaluate the safety and efficacy of LC in patients with varying degrees of obesity.
• To determine the correlation between BMI and the rates of conversion to open surgery, complications, and hospital stay.
• To assess LC as a viable option for morbidly obese patients.

Main Methods:

• Retrospective analysis of 1,804 patients undergoing LC for gallstones (May 1992 - January 2004).
• Patients categorized into five BMI groups: <24.9, 25.0-29.9, 30.0-34.9, 35.0-39.9, and ≥40 kg/m².
• Outcomes analyzed included conversion rates, complication rates, operating time, and hospital stay.

Main Results:

• No significant correlation found between BMI and conversion to open cholecystectomy (P=0.593).
• No significant correlation found between BMI and perioperative complication rates (P=0.944).
• Obesity (BMI ≥30 kg/m²) was associated with longer operating times (P<0.001), but hospital stay remained similar across BMI groups.

Conclusions:

• Laparoscopic cholecystectomy is a safe and effective procedure for patients with morbid obesity.
• Low risks of conversion and complications support LC as the preferred approach for obese individuals.
• Benefits include rapid mobilization and shorter hospital discharge, particularly advantageous for obese patients.
