Background: Ulcerative colitis frequently requires surgery as a definitive management strategy. The colonic specimen can be extracted from various sites including a midline incision, the stoma site, or a Pfannenstiel incision. It is unclear if one extraction site offers improved outcomes and fewer complications. Methods: A retrospective review of charts obtained of colorectal surgery patients was conducted for all patients with ulcerative colitis who underwent a subtotal colectomy between 2008 and 2016 at a single tertiary care institution. Demographic data and outcomes data including parastomal and incisional hernias, advanced wound/ostomy certified nurse referrals, surgical site infections, reoperations, and readmissions were collected. Univariate and multivariate analyses were completed to detect any significant differences in outcomes between groups based on extraction site (midline incision, stoma site, or Pfannenstiel incision). Results: Univariate analysis did not show any statistical differences between groups in regard to outcomes. Stoma site extraction did not statistically differ from midline extraction in regard to hernias, advanced ostomy referrals, infections, or reoperations, but midline incision extraction did have a lower risk of readmission (OR = 0.56, p = 0.0066). Pfannenstiel extraction had lower risk of incisional hernias (OR = 0.25, p = 0.0002), advanced ostomy referrals (OR = 0.45, p = 0.0164) and readmission (OR = 0.26, p < 0.0001) as compared to stoma site extraction. Conclusions: While stoma site extraction can be successfully performed for most patients requiring subtotal colectomy for ulcerative colitis, Pfannenstiel extraction leads to the fewest number of complications and provides the most consistent results.
