BackgroundIn comparison to a traditional cholecystectomy (open), the laparoscopic cholecystectomy approach provides a number of benefits and has been demonstrated in some studies to have a greater complication rate. The conversion rate from laparoscopic to open surgery ranged between 2% and 15%. A preoperative scoring or grading system (based on age, sex, history, clinical examination, laboratory, and sonographic results) was developed by Nassar et al., to anticipate the challenge of laparoscopic cholecystectomy. So, we conducted this study to assess the degree of difficulty in faced during laparoscopic cholecystectomy using an intraoperative scoring system and validate the same using the preoperative scoring system. MethodsWe conducted this study in the department of General Surgery among 105 patients who underwent laparoscopic cholecystectomy during the defined study period of one year. We performed the preoperative workup for all patients. A preoperative scoring or grading system developed by Nassar et al., in 2020 was used. In our study, laparoscopic cholecystectomy was performed by surgeons having a minimum of eight years of hands-on experience in laparoscopic surgeries. An intraoperative scoring or grading system for the degree of difficulty during laparoscopic cholecystectomy, developed by Sugrue et al., in 2015 was used. The Chi-square test was applied to assess the association between preoperative variables and the intraoperative score grading. We have also performed the receiver operating characteristic (ROC) curve analysis to validate the preoperative score in predicting the intraoperative findings. All tests were considered statically significant if the p-value was < 0.05. ResultsIn our study, a total of 105 patients were included in the study and the mean age of patients was 57.6±16.4 years. The male patients were 58.1% and the remaining 41.9% were females. The primary diagnosis was cholecystitis among 44.8% of patients and 2.9% of patients were diagnosed with pancreatitis. Among enrolled patients, laparoscopic cholecystectomy was done on an emergency basis among 2.9% of subjects. During the laparoscopic cholecystectomy, among 21.0% and 30.5% of patients, there was a severe and extreme degree of difficulty respectively. In our study, the conversion rate from laparoscopic to open cholecystectomy was 8.6%. In our study, we found that at a preoperative score of 6, the sensitivity and specificity for predicting easy cases were 88.2% and 73.8%, respectively, and had an accuracy of 88.6% for easy cases and 68.5% for difficult cases. ConclusionWhen grading the difficulties of doing a laparoscopic cholecystectomy and determining the severity of cholecystitis, this intraoperative scoring system is effective and accurate. Additionally, it signifies the need for conversion from laparoscopic to open cholecystectomy in cases of severe cholecystitis.
