Perioperative care of clinically severely obese patients presents numerous unique challenges. These patients have distinctive issues with regard to cardiovascular, pulmonary, and thromboembolic complications. In addition, hospital equipment must be able to accommodate the body habitus of this population. ⋯ The management of the morbidly obese patient requires meticulous preoperative, intraoperative, and postoperative care. Colorectal surgeons should be familiar with obesity-related problems when treating colorectal disease processes in this patient population. The associated comorbid illnesses in this population, as well as the technical difficulties regularly posed by them, make laparoscopic colectomy a more challenging procedure than normally encountered in the nonobese patient population.

Comparative Study
Propensity score analysis in observational studies: outcomes after abdominal aortic aneurysm repair.
Large databases composed of well-designed prospectively collected cohort data provide an opportunity to examine and compare healthcare treatments in actual clinical practice settings. Because the analysis of these data often leads to a retrospective cohort design, it is essential to adequately adjust for lack of balance in patient characteristics when making treatment comparisons. We used matched propensity scoring in a cohort of patients undergoing elective aneurysm repair as an illustrative example of this important statistical method that adjusts for baseline characteristics and selection bias by matching covariables. ⋯ We used a propensity score approach to examine outcomes after elective AAA repair to statistically control for many factors affecting both treatment selection and outcome. Patients who underwent elective EVAR had substantially lower perioperative mortality and morbidity rates compared with patients having open repair, which was not explained solely by patient selection in an observational dataset.

To investigate the interactions between splenectomy and perioperative transfusion in gastric cancer patients. ⋯ Splenectomy does not appear to abrogate the adverse effect of perioperative transfusion on prognosis in gastric cancer patients. Moreover, it may increase postoperative recurrence in transfused patients.

Acute traumatic rupture of the descending thoracic aorta is usually considered a surgical emergency; a conventional surgical approach carries high morbidity and mortality rates in the perioperative period. Endovascular surgery has recently been considered as providing a new therapeutic strategy for these patients. The aim of our study was to evaluate the feasibility along with early and midterm results of this procedure in our experience. ⋯ The treatment of acute traumatic rupture of the descending thoracic aorta with stent graft is a feasible and safe technique; it provides low morbidity and mortality rates in the early postoperative period, and midterm results are encouraging. However, long-term studies are worthwhile to evaluate the effectiveness and the durability of this procedure.

Reduced resident work hours sparked debate regarding lifestyle of clinical faculty. We hypothesized surgery department chairs would not be supportive of part-time clinical faculty (PTF) and would be reluctant to grant requests to reduce total institutional commitment (TIC) or total professional effort. ⋯ Contrary to our hypothesis, surgery department chairs appear to be supportive of PTF and were interested in discussing this further.
