title: Right Versus Left-Sided Colectomies: A Comparison of Outcomes.
abstract: Surgeons often consider that a right colectomy (RC) carries less risk than a left or sigmoid colectomy (L/SC). Our aim was to compare outcomes between RC and L/SC. Review of the Carolinas Medical Center National Surgical Quality Improvement Program data from 2013 to February 2015 was performed. Procedures were categorized as RC Versus L/SC based on current procedural terminology codes for both open and laparoscopic colectomies. Demographics and minor and major complications were evaluated using standard statistical methods. A total of 164 RC and 211 L/SC were studied. RC patients were older (63.9 ± 14.2 vs 59.4 ± 13.0, P < 0.001). Patients undergoing RC had more comorbidities, and 64.6 per cent had an American Society of Anesthesiologist (ASA) Class III or above Versus 51.7 per cent of those undergoing L/SC (P = 0.02). RC had significantly higher rates of postop urinary tract infection (7.3% vs 2.8%, P = 0.04) and postop transfusions (P = 0.01). Average length of stay was longer for RC (10.1 ± 8.6 days vs 8.3 ± 7.0 days, P < 0.01). After controlling for ASA class, preoperative hematocrit and surgical technique (lap Versus open), multivariate analysis indicated that there were no longer any significant differences in outcomes between RC and L/SC. There were no differences between the group complications including superficial or deep surgical site infections, anastomotic leak, myocardial infarction (MI), pneumonia, or 30-day mortality. RC patients tended to be sicker and had more medical complications postop with initial evaluation of the data. However, when controlling for ASA, hematocrit, and techniques, there were no differences in complications when RC was compared to L/SC. The belief that L/SC has a higher rate of complications compared to RC is not supported.
