Involvement of a skill-qualified surgeon favorably influences outcomes of laparoscopic cholecystectomy performed for acute cholecystitis.

OBJECTIVE: The Endoscopic Surgical Skill Qualification System (ESSQS) was developed by the Japan Society for Endoscopic Surgery as a means of subjectively assessing the proficiency of laparoscopic surgeons. We conducted a study to evaluate how involvement of an ESSQS skill-qualified (SQ) surgeon influences short-term outcomes of laparoscopic cholecystectomy performed for acute cholecystitis. Previous reports suggest that assessment of the video-rating system is a potential tool to discriminate laparoscopic surgeons' proficiency and top-rated surgeons face less surgical mortality and morbidity in bariatric surgery. METHODS: Data from the National Clinical Database regarding laparoscopic cholecystectomy performed for acute cholecystitis between January 2016 and December 2018 were analyzed. Outcomes were compared between patients grouped according to involvement vs. non-involvement of an SQ surgeon. Outcomes were also compared between patients grouped according to whether their operation was performed by biliary tract-, stomach-, or colon-qualified surgeon. RESULTS: Of the 309,998 laparoscopic cholecystectomies during the study period, 65,295 were suitable for inclusion in the study and 13,670 (20.9%) were performed by an SQ surgeon. Patients' clinical characteristics did not differ between groups. Thirty-day mortality was significantly lower in the SQ group (0.1%) 16/13,670 than in the non-SQ group (0.2%) 140/51,625 (P = 0.001). Thirty-day mortality was [0.1% (9/7173)] in the biliary tract-qualified group, [0.2% (5/3527)] in the stomach-qualified group, and [0.1% (2/3240)] in the colon-qualified group. CONCLUSION: Surgeons with ESSQS certification outperform the non-skilled surgeons in terms of surgical mortality in 30 and 90 days. Further verification of the value of the ESSQS is warranted and similar systems may be needed in countries across the world to ensure patient safety and control the quality of surgical treatments.
