Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A prospective cohort study comparing the surgical outcome of patients who underwent emergent laparoscopic cholecystectomy guided by indocyanine green cholangiography (ELC-ICGC) versus conventional laparoscopic operation. The patients were recruited in the Peking Union Medical Colleg Hospital emergency department from 1st August 2020 to 1st Feburary 2024. A database was prospectively established to collect related data. The surgical outcomes of ELC-ICGC and conventional ElC will be compared.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Acute calculous cholecystitis, typically occurs in patients with gallstones, accounts for 90 to 95% of acute cholecystitis. Emergent laparoscopic cholecystectomy (ELC) is the major treatment option. Traditionally, the time frame for ELC is generally considered to be within 72 hours from the onset of symptoms. However, with the development of surgical techniques, nowadays, ELC is also considered for patients with symptoms onset within 10 days and hospital stays within 7 days. The determination of the time frame for ELC in acute cholecystitis is primarily based on the risk of complications occurring. Comparing to delayed laparoscopic cholecystectomy (DLC), ELC has advantages in post-operative complications in patients with symptoms onset within 72 hours. Post-operative complications for both DLC and ELC include bile leaks, intestinal obstruction, ascites, intraperitoneal hemorrhage, would bleeding and hematoma, wound infection and calculus remaining. Most of them associate with intraoperative procedures. Emergent laparoscopic cholecystectomy guided by indocyanine green (ICG) cholangiography (ELC-ICGC), comparing to conventional LC, potentially can help the surgeons to identify bile tracts and therefore may reduce the complications.

From August 1st 2020, the AC patients undergoing LC in PUMCH were prospecteively registered and a database was established to collect related data.

Till 1st Feburary 2024, about 750 cases of ELC were performed. The surgeons chose to perform either conventional ELC or ELC-ICGC based on their discretion. The patients were followed up within one month after discharge in out patient clinic or telephone interview. We plan to analyze the data from the prospectively established- database.

The surgical outcomes are evaluated by both intraoperative events and postoperative events. Intraoperative events contain the following items: (1) incidence of intraoperative accidental bile tract injury, (2) intraoperative bleeding (volume), (3) operation time. Postoperative events contain the following items: (1) incidence of complications staging 2 and above according to Clavien Dindo Grade during hospital stay, (2) duration of postoperative hospital stay. The economic effectiveness is evaluated by cost of hospital stay.

The surgical outcomes of these two procedures will be compared.
