Decline of open surgical experience for general surgery residents

Abstract

Background: Minimally invasive surgery is now preferred to open in many surgical procedures. This has led to changes in training to ensure skills acquisition and education in minimally invasive technique. There have been limited data regarding the effect of the number of open procedures being performed in training. The aim of this paper is to examine the relationship in trends for open and laparoscopic procedures performed by general surgery residents.

Methods: A retrospective review of the Accreditation Council for Graduate Medical Education publicly available resident case log statistical reports for the academic years from 1999-2000 to 2017-2018 was performed for laparoscopic and open anti-reflux surgery, appendectomy, colectomy, splenectomy, and inguinal hernia repair. The data were grouped by time period and compared to evaluate changes in operative patterns.

Results: The mean number for all (open and MIS) of the selected procedures increased from 159.1 in 2000 to 223.8 in 2018 (40.7%). The mean number of laparoscopic cases increased from 23.6 to 135.6 (462%), and open decreased from 135.5 to 88.2 (- 34.9%). There was a significant decrease in the average number of open procedures performed in each period among anti-reflux operations (3.4, 1.8, 1.5, 0.7, p < 0.01), appendectomy (30.7, 23.4, 13.6, 6.8, p < 0.01), and splenectomy (3.0, 2.0, 1.6, 1.4, p < 0.05); the number of open colectomies decreased significantly from Period 2 to Period 4 (46.1, 38.5, 33.4, p < 0.02). There was a significant increase in the number of laparoscopic procedures performed in each period among appendectomy (13.1, 28.3, 48.9, 58.4, all p < 0.02), colectomy (2.9, 10.1, 19.1, 23.4, all p < 0.01), and inguinal hernia repair (9.7, 14.9, 25.6, 34.1, all p < 0.01).

Conclusion: The number of open procedures performed by general surgery residents continues to decline despite an increase in total cases reported. The reduction in open surgical experience may result in surgeons who lack technical skills to safely complete open procedures.
