Preoperative Prediction of Difficult Laparoscopic Cholecystectomy Using Scoring System: A Clinical Observational...

Area of Science:

• Surgical Oncology
• Gastroenterology
• Medical Diagnostics

Background:

• Laparoscopic cholecystectomy (LC) is the standard treatment for gallstone disease.
• 5-10% of LC cases require conversion to open surgery due to complications or complex anatomy.
• Preoperative identification of difficult LC cases can optimize surgical planning and patient communication.

Purpose of the Study:

• To assess the efficacy of a novel preoperative scoring system in predicting the difficulty of LC.
• To guide surgical preparedness and resource allocation for challenging LC procedures.

Main Methods:

• A prospective observational study involving 150 patients undergoing elective LC.
• Preoperative clinical, biochemical, and ultrasound data were collected and scored (0-15 points).
• Patients were categorized into risk groups, with analysis using chi-square, Fisher's exact tests, and ROC curves.

Main Results:

• Difficult LC was observed in 22% of patients (very difficult in 2%).
• Key predictors of difficult LC included advanced age, male sex, prior cholecystitis, obesity, specific ultrasound findings (thickened GB wall, impacted stone, contracted GB, CBD dilation), and elevated ALP.
• The scoring system demonstrated high predictive accuracy (AUC 0.927), with a score >6 indicating difficulty with 75.76% sensitivity and 98.29% specificity.

Conclusions:

• The developed preoperative scoring system reliably predicts difficult LC.
• Patients with high scores (>6) may benefit from triage to experienced surgeons or consideration for early open conversion to minimize complications.
