In a prospective cohort study involving 60 morbidly obese patients with type 2 diabetes, Leonetti and coauthors compare the effect of sleeve gastrectomy vs medical therapy on type 2 diabetes mellitus and other obesity-related comorbidities. An invited critique suggests that obese diabetic patients should have access to bariatric surgery in appropriate clinical circumstances.
To assess factors associated with morbidity and mortality following the use of robotics in general surgery, Buchs and colleagues conducted a retrospective review of prospectively collected data from patient medical records. The review involved 884 patients who underwent a robotic procedure at the researchers’ institution between April 2007 and July 2010.
To analyze the preliminary experience with the new da Vinci single-site technology for cholecystectomy, Pietrabissa and colleagues conducted a prospective longitudinal observational study of 100 consecutive da Vinci single-site cholecystectomies at 5 Italian centers of robotic general surgery. Outcome measures included feasibility without conversion and the absence of major complications.
Morikawa and coauthors used multivariate negative binomial regression of data from 2 US nationwide prospective cohort studies to identify operator-independent factors that influence the total and negative lymph node counts in colorectal cancer resection specimens.
Kang et al evaluate trends before and after the application of the International Classification of Diseases, Ninth Revision codes for laparoscopic colorectal surgery in 2008.
Glance et al examine longitudinal trends in mortality for injured patients admitted to trauma centers.
Postoperative survival rates for Japanese patients with gastroesophageal cancer exceed Western rates. Hanna and coauthors examined whether extended lymphadenectomy will improve survival rates in Western patients.
Mistry and coauthors examine whether the early removal of nasogastric tubes adversely affects major pulmonary complications and anastomotic leak rates. See commentary by Low.
To correlate microscopic margin status with survival and local control in a large cohort of patients from a high-volume pancreatic cancer center, Gnerlich and coauthors performed a retrospective database review of 285 patients who underwent pancreaticoduodenectomy for pancreatic adenocarcinoma.
To investigate whether TeamSTEPPS is helpful to medical students, Meier and coworkers integrated a module into the resident readiness elective and measured improvement of self-assessment scores, multiple-choice examination scores, and performance ratings of videotaped simulation scenarios before and after intervention. See commentary by McCoy and Carty.
With the increase in the incidence of esophageal cancer, minimally invasive techniques have been developed. In a retrospective meta-analytic study, Dantoc and coauthors compared oncologic outcomes between open and minimally invasive esophagectomy.
Vaid and Nicolson report a case series of 5 patients for whom a fibrin sealant was used during perineal wound closure.
