A Scoring System to Predict Difficult Laparoscopic Cholecystectomy: A Five-Year Cross-Sectional Study

Area of Science:

• Minimally Invasive Surgery
• Surgical Risk Assessment
• Gastrointestinal Surgery

Background:

• Laparoscopic cholecystectomy is the preferred surgical method due to its advantages over open cholecystectomy.
• Despite its benefits, laparoscopic cholecystectomy carries a risk of complications, necessitating preoperative identification of risk factors.
• Existing scoring systems for predicting intraoperative difficulties lack consistency and reliability.

Purpose of the Study:

• To validate a preoperative scoring system designed to predict the difficulty of laparoscopic cholecystectomy.
• To assess the reliability and practicality of a novel scoring system in identifying challenging cases.

Main Methods:

• A nonrandomized retrospective descriptive study was conducted involving 134 patients.
• A preoperative score was calculated based on patient history, clinical examination, and sonographic findings.
• Receiver Operating Characteristic (ROC) curve analysis determined cutoffs for easy-difficult (3.5) and difficult-very difficult (7.5) cases.

Main Results:

• Significant predictors of difficult laparoscopic cholecystectomy included a history of acute cholecystitis, high BMI, abdominal scars, palpable gallbladder, thick gallbladder wall, and elevated leukocyte count.
• The scoring system demonstrated a high area under the ROC curve (0.849 for easy-difficult; 0.779 for difficult-very difficult).
• Sensitivity and specificity for the easy-difficult cutoff were 72.6% and 87.5%, respectively; for the difficult-very difficult cutoff, they were 70.0% and 84.5%.

Conclusions:

• The evaluated preoperative scoring system is a reliable tool for predicting the difficulty of laparoscopic cholecystectomy.
• The scoring system offers significant benefits for preoperative risk assessment and surgical planning.
• Further large-scale, randomized prospective multicentric studies are recommended to fully validate the scoring system's efficiency.
