Abstract
Background: Despite the growing importance and increased use of laparoscopy for gallbladder diseases in Saudi Arabia, several factors reportedly result in conversion to open surgery. This leads to increased operative time and increased hospital resource utilization, and, importantly, it impacts patient welfare. Although laparoscopic cholecystectomy and its conversion rates have been investigated in Saudi Arabia, there is little information on the factors associated with this conversion. Therefore, we analyzed the prevalence and factors associated with the conversion from laparoscopic to open cholecystectomy.
Materials and methods: This was a quantitative, retrospective, observational, crosssectional study. We reviewed the health care records of all patients who underwent laparoscopic cholecystectomy during the study period (January 2014-December 2015). We analyzed patient demographics, preoperative factors, ultrasound findings, and intraoperative factors associated with higher conversion rates. We calculated means, SDs, and medians for numerical variables and percentages and frequencies for nominal variables. The chi(2) and two-tailed t tests were used to compare the categorical and continuous variables, respectively, between patients who underwent laparoscopic cholecystectomy and those who underwent conversion to open cholecystectomy to analyze their relationship with the possibility of conversion. Statistical significance was considered at P < 0.05.
Results: Age > 40 years, diabetes, history of admission for gallstones, and increased total bilirubin, direct bilirubin, and alkaline phosphatase levels were the preoperative factors and adhesions, bleeding, and stone spillage were the intraoperative factors associated with conversion.
Conclusion: Recognizing the factors for conversion would improve treatment planning and help predict when conversion may be necessary.
