Validation of prostic scale of conversion to open surgery in laparoscopic colecistectomy

Abstract

Introduction: Conversion to open surgery is a complication of laparoscopic cholecystectomy, either because of difficulty dissection or a lack of surgeon expertise. It is currently difficult to predict the difficulty of laparoscopic gallbladder surgery.

Objective: Evaluate the sensitivity of ultrasound for cholecystitis and cholelitiasis and its relationship to transoperative findings in gallbladder surgeries

Material and methodsA retrospective observational study was conducted with a review of the medical histories of those patients surgically intervened by gallbladder pathologies and who have ultrasound as a diagnostic medium at the Ambato Teaching General Hospital June to December 2018. Possible surgical difficulty was evaluated with an ultrasound progtostic scale and subsequently compared with surgical findings and conversion.

Results: The correlation of surgical difficulty (surgery greater than 90 min or converted) in relation to the predictive scale (possible complicated surgery score 5) is 73% (sensitivity) and the probability that the scale predicts uncomplicated surgery is 71%( or: 7,785 (IC: 0.789 –78,511), with a Fisher test (modified X2) of 2,225 with a p x 0.074. The relationship is not statistically significant.

Conclusion: The ultrasound progmatic scale used in patients at Ambato Teaching General Hospital does not predict the surgical difficulty of patients undergoing laparoscopic gallbladder surgery
