Emergency cholecystectomy: risk factors and impact of delay on electively booked patients, a 5-year experience of a tertiary care center.

Background: Gallstone disease is one of the most resource-intensive surgical conditions. Despite the significant burden of emergency cholecystectomy on healthcare system, there is lack of research assessing the risk factors predisposing scheduled elective cholecystectomy patients to emergency surgery. Characterization of patients with gallstones helps to prioritize delivery of health care to avoid urgent surgery. The objective of the present study is to analyze risk factors associated with emergency cholecystectomy and assess the impact of delay on electively scheduled patients.

Methods: This retrospective cohort study at a tertiary care center in Jeddah, Saudi Arabia, between January 2018 and June 2022. Net total of 823 patients.The study has collected data retrospectively from an electronic health record system. The data were entered and coded in excel sheet. All statistical tests were 2-sided and were conducted using SAS statistical software version 9.4 (SAS Institute Inc. Cary, NC).

Results: A total of 823 patients met the inclusion criteria and enrolled in the analysis. Among them, 129 patients (15.67%) underwent emergency cholecystectomy, while 694 patients (84.33%) underwent elective cholecystectomy. The waiting time in days was significantly longer for patients undergoing emergency cholecystectomy (mean of 362 days) compared to those undergoing elective cholecystectomy (mean of 305 days). Patients with more than two previous ED visits were over five times more likely to undergo emergency cholecystectomy compared to those who had never visited the ED previously (p-value < 0.0001) Moreover, patients diagnosed with acute cholecystitis and pancreatitis were more likely to undergo emergency cholecystectomy compared to those not diagnosed with these conditions (p-value < 0.0001; p-value 0.02).

Conclusion: Analysis of risk factors and delay in patients with gallstones scheduled for elective cholecystectomy demonstrates that long waiting times, severity of the initial visit setting, Hemolytic anemia, and male gender were significantly related to emergency cholecystectomy. Independent risk factors for emergency cholecystectomy were frequency of ED visits, acute cholecystitis, pancreatitis, and CBD stone. Patients with these risk factors should be given priority on the waiting list to avoid emergency surgery. Future research is required to design a scoring system or specific criteria for elective patients at risk of developing acute cholecystitis.
