Use of laparoscopy in general surgical operations at academic centers

Abstract

BackgroundLaparoscopy is commonly being used in many different types of general surgical procedures. The aim of the present study was to examine the use of laparoscopy and perioperative outcomes in 7 general surgical operations commonly performed at U.S. academic medical centers. MethodsThe clinical data of patients who underwent 1 of the 7 general surgical operations from 2008 to 2012 were obtained from the University HealthSystem Consortium database. The University HealthSystem Consortium database contains data from all major teaching hospitals in the United States. The 7 analyzed operations included only elective, inpatient procedures (except for appendectomy): open and laparoscopic antireflux surgery for gastroesophageal reflux, colectomy for colon cancer or diverticulitis, bariatric surgery for morbid obesity, ventral hernia repair for incisional hernia, appendectomy for acute appendicitis, rectal resection for rectal cancer, and cholecystectomy for cholelithiasis. The outcome measures included the number of procedures, rate of laparoscopy, rate of conversion to laparotomy, and in-hospital mortality. ResultsDuring the 3.5-year period, 53,958 patients underwent bariatric surgery, 13,918 patients underwent antireflux surgery, 8654 patients underwent appendectomy, 8512 patients underwent cholecystectomy, 29,934 patients underwent colectomy, 17,746 patients underwent ventral hernia repair, and 4729 patients underwent rectal resection. The present rate of laparoscopic use was 94.0% for bariatric surgery, 83.7% for antireflux surgery, 79.2% for appendectomy, 77.1% for cholecystectomy, 52.4% for colectomy, 28.1% for ventral hernia repair, and 18.3% for rectal resection. In-hospital mortality was greatest for colorectal resection (.38%–.58%). In-hospital mortality for bariatric surgery (.06%) was comparable to that for appendectomy (.01%), cholecystectomy (.27%), antireflux surgery (.15%), and ventral hernia repair (.20%). The rate of laparoscopic conversion to open surgery was lowest for bariatric surgery (.89%) and greatest for rectal resection (16.4%). ConclusionWithin the context of academic centers and elective, inpatient procedures, bariatric surgery had the greatest use of laparoscopy and the lowest rate of laparoscopic conversion to open surgery. The mortality for laparoscopic bariatric surgery is now comparable to that of laparoscopic cholecystectomy, ventral hernia repair, appendectomy, and antireflux surgery.
