Inclusion criteria
Inclusion criteria: Patients who were 18 years or older and underwent laparoscopic cholecystectomy from April 1, 2015, to March 31, 2022, are included in this study. It should be noted that cholecystectomy is not commonly performed on children, but rather on adults.
Exclusion criteria
Exclusion criteria: 1. Patients who have undergone other surgeries, besides cholecystectomy, and have been registered on the same day for laparoscopic cholecystectomy by DPC code due to the increased uncertainty associated with such cases. 2. Patients who have undergone previous or total gastrectomy, as this information is verifiable through their surgical history since there was either no stomach or minimal stomach tissue remaining after the procedure, the term "total gastrectomy" or "gastrectomy" is applicable. 3. Patients who have undergone surgery using a single port are usually excluded from our analysis because the use of a single port significantly restricts the field of view during surgery compared to using multiple ports. It is worth noting that the number of surgeons at our hospital who utilize this technique is quite limited. 4. Patients who had epidural catheter insertion, because we anticipate a high degree of surgical difficulty. 5. Patients with end-stage kidney disease due to uncertainties in delayed drug discharge and systemic status 6. Patients who had histories of laparotomy because we anticipate a high degree of surgical difficulty. 7. Those who have offered their refusal to participate in the study
