Risk Factors for Conversion to Open Surgery in Patients With Acute Cholecystitis Undergoing Interval Laparoscopic Cholecystectomy

ABSTRACT

Introduction: Laparoscopic cholecystectomy for acute cholecystitis is associated with higher rate of conversion to laparotomy. The value of several factors that might influence the rate of conversion is analysed. Materials and Methods: In a retrospective analysis of a prospective database, the medical records of patients who underwent laparoscopic cholecystectomy from May 1998 to June 2004 were reviewed. Patients who had acute cholecystitis and had undergone interval laparoscopic cholecystectomy were included in this study. Results: Out of 1000 laparoscopic cholecystectomies, 201 were operated on for acute cholecystitis. One hundred and forty-five patients (72.3%) underwent succesful laparoscopic cholecystectomy and 56 patients (27.7%) needed conversion to open cholecystectomy. Patient’s age (P = 0.031), total white cell count (P = 0.014), total bilirubin (P = 0.002), alkaline phosphatase (P = 0.003) and presence of common bile duct stone (P = 0.001) were found to be independently associated with conversion. Conclusion: Laparoscopic cholecystectomy can be performed safely for acute cholecystitis. Predictors of conversion will be helpful when planning the laparoscopic approach and for counselling patients preoperatively.


Laparoscopic cholecystectomy has become a routine surgical procedure in general surgical units all over the world. Its implementation has expanded dramatically and is considered a feasible and safe approach even for acute cholecystitis.1,2 Laparoscopic management of acute cholecystitis may still be associated with increased risks of complications such as bile duct injury and abscess formation.3 The conversion rate to open cholecystectomy is also higher compared to elective cases.4
