BACKGROUND: Laparoscopic cholecystectomy has become the gold standard in the treatment of symptomatic
cholelithiasis. Some patients require conversion to open surgery and several preoperative variables have been
identified as risk factors that are helpful in predicting the probability of conversion.However,there is a need to devise a
risk-scoring system based on the identified risk factors to (a) predict the risk of conversion preoperatively for selected
patients, (b) prepare the patient psychologically, (c) arrange operating schedules accordingly, and (d) minimize the
procedure-related cost and help overcome financial constraints,which is a significant problem in developing countries.
AIM: This study was aimed to evaluate preoperative risk factors for conversion from laparoscopic to open
cholecystectomy in our setting.
MATERIALS AND METHODS:A case control study of patients who underwent laparoscopic surgery from May 2016 to
April 2017 at Shere Kashmir Institute of Medical Sciences, Srinagar. All those patients who were converted to open
surgery (n = 73) were enrolled as cases.Two controls who had successful laparoscopic surgery (n = 146) were matched
with each case for operating surgeon and closest date of surgery.
RESULTS:The final multivariate model identified two risk factors for conversion:ultrasonography signs of inflammation
(adjusted odds ratio [aOR] = 8.5;95% confidence interval [CI]:3.3,21.9) and age > 60 years (aOR = 8.1;95% CI:2.9,22.2)
after adjusting for physical signs,alkaline phosphatase and BMI levels.
CONCLUSION: Preoperative risk factors evaluated by the present study confirm the likelihood of conversion.
Recognition of these factors is important for understanding the characteristics of patients at a higher risk of conversion
