( Hon) Department of Colorectal Surgery Digestive Disease Institute Cleveland Clinic, Ohio Slide 2 Aim: To demonstrate trends in CR practice from 1989 to 1996 To compare the 1 year technical experience of a CR resident with the 5 years total of a GS resident CR resident performs more anorectal operations more endoscopic procedures more index abdominal operations in 1 year than GS resident does in 5 years 1 year of training in CR trains a true specialist with unique expertise Schoetz DCR 1998 Slide 3 Data from American Board of Colon and Rectal Surgery (ABCRS) database (1994 to 2005) CR training programs increased from 28 to 39 (28% increase) CR residency positions increased from 50 to 66 (24% increase) Anorectal patients per resident remained constant over the study period Sigmoidoscopy decreased substantially Rigid (67 to 44 per resident) Flexible (135.5 to 39 per resident) Colonoscopy increased (209 to 264 per resident) Schoetz J Am Coll Surg 2006 Slide 4 Perineal procedures for rectal prolapse consistently comprise 50% to 60% of the total procedures for prolapse Low anterior resection APR ratio=3/1 Coloanal anastomoses have steadily increased Radical cancer operations continue to make up a sizeable portion of abdominal surgery volume in training programs Surgery for colon cancer have been between 52.4% and 57.9% of the total number of resections for colorectal cancer Schoetz Jr J Am Coll Surg 2006 Slide 5 General Surgery Colorectal Surgery Colectomy 14.9 62.2 IPAA 1.5 10.7 APR 3.2 7.3 Gen Surgery versus Colon Rectal Surgery Residents Colon Procedures 1995-1996 Slide 6 Laparoscopic Colorectal Surgery 3.6% laparoscopic procedures performed in 1994, vs. 24.3% in 2005 The greatest increase being in diverticular resections (6.5 % in 1994 vs. 44.7% in 2005) In 1994 5.6% of colon resections performed laparoscopically for cancer vs. 41.1% in 2005 Schoetz Jr J Am Coll Surg 2006 Slide 7 Data from Accreditation Council for GME General surgery residents (2000-2004) The average number of LAP colectomy/GS resident/career increased from 1.84 to 4.61 Colorectal surgery residents (1994-2005) Number of CR residents steadily increased to 66 by 2005 The total number of open or LAP cases increased from 8342 to 13267 The average LAP cases/CR resident increased from 6.3 in 1993-1994 to 45.3 in 2004-2005 Charron DCR 2007 Slide 8 Colorectal surgery residents (1994-2005) A total of 2987 LAP cases were performed in 2005 Average CR resident recorded 45.3 LAP cases in 2005 (colon=30, rectal=9.4, other=5.9) 1999-2000, 3098 segmental colectomy performed (LAP=330) 2004-2005, 4394 segmental colectomy performed (LAP=1771) LAP low anterior resection increased from 32 to 248 (1999 to 2005) LAP APR increased from 11 to 48 (1999 to 2005) Charron DCR 2007 Slide 9 Comparison of LAP colon resection experience for GS vs. CR residents 2003-2004 The average number of laparoscopic colon resections by GS vs. CR (4.61 vs. 20.2) The majority of GS resident experience was acquired in the chief year, with an average of 2.69 of 4.61 cases Charron DCR 2007 Slide 10 Conclusions Learning curves for LAP colectomy are reported in the range of 20 to 60 cases CR resident experience is trending toward this threshold Recent general surgery graduates may be lacking the appropriate volume to reach proficiency in LAP colorectal surgery Charron DCR 2007 Slide 11 Segmental Colectomy 37 LAR 11 APR 4 IPAA 7 Minimum Numbers ABCRS Slide 12 Slide 13 Slide 14 Slide 15 Slide 16 Slide 17 Slide 18 Slide 19 Slide 20 Slide 21 Slide 22 Slide 23 Slide 24 Slide 25 Slide 26 Slide 27 Slide 28
