Background: Laparoscopic cholecystectomy is the preferred surgical operation for symptomatic gallstone disease. Conversion of laparoscopic cholecystectomy to open surgery is used to prevent intra-abdominal organ injury, for open common bile duct exploration and to repair intra-abdominal organ injury.
Objective:The objective of this chapter is to review risk factors and predictive models for conversion of laparoscopic cholecystectomy to open surgery, and surgical quality outcome measures.
Methods:A narrative literature review using Pubmed, Medline, Cochrane library databases and Google search engine is described.Results: From the literature review, patient-and surgeon-related risk factors and predictive models for conversion of laparoscopic cholecystectomy to open surgery were identified. Patient-dependent risk factors included preoperative and intraoperative variables. Current conversion of laparoscopic cholecystectomy to open surgery predictive models use only patient-dependent risk factors and were not tested on an independent sample of patients. Surgical quality outcome measures incorporate an association between conversion and intra-abdominal organ injury that demonstrates that conversion was used as an emergency strategy to repair injuries rather than a safety measure.
Conclusion:Conversion of laparoscopic cholecystectomy to open surgery risk stratification based on patient-and surgeon-dependent variables may allow a better management of the patient to keep conversion at low rates and to maintain benefits of minimally invasive surgery.
