Predicting Difficult Laparoscopic Cholecystectomy Based on Clinicoradiological Assessment

Area of Science:

• Surgical Innovation
• Gastrointestinal Surgery
• Minimally Invasive Procedures

Background:

• Laparoscopic cholecystectomy (LC) is the standard treatment for gallstones.
• 1-13% of LCs require conversion to open surgery due to various factors.
• Predictive criteria for difficult LC and conversion are lacking.

Purpose of the Study:

• To identify clinical and radiological parameters for predicting difficult LC.
• To assess factors that indicate conversion from LC to open surgery.

Main Methods:

• Prospective study of 180 patients undergoing LC (October 2010 - October 2014).
• Assessed gallbladder wall thickness, pericholecystic fluid, number of previous attacks, and total leukocyte count (TLC).
• Statistical analysis performed using Z-test.

Main Results:

• 70% of LCs were easy, 24.44% difficult, and 5.56% required conversion.
• Conversion rate was 5.6%.
• Significant predictors for difficult LC and conversion included TLC > 11000, >2 previous attacks, gallbladder wall thickness >3mm, and pericholecystic fluid.

Conclusions:

• Difficult LC and conversion can be predicted preoperatively.
• Key predictive factors include prior cholecystitis attacks, white blood cell count, gallbladder wall thickness, and pericholecystic fluid.
