This repair provides the benefits of an open posterior component separation with transversus abdominis release and maintains the biomechanics of a functional abdominal wall, all while simultaneously benefitting from the advantages of mesh reinforcement in a modified Sugarbaker configuration. Our clinical experience with this novel technique to this point has been positive.
The liver is the largest gland in the body occupying 2.5% of total body weight and providing a host of functions necessary for maintaining normal physiological homeostasis. Despite the complexity of its functions, the liver has a homogenous appearance, making hepatic anatomy a challenging topic of discussion. To address this issue, scholars have devoted time to establishing a framework for describing hepatic anatomy to aid clinicians. Work by the anatomist Sir James Cantlie provided the first accurate division between the right and left liver in 1897. The French surgeon and anatomist Claude Couinaud provided additional insight by introducing the Couinaud segments on the basis of hepatic vasculature. These fundamental studies provided a framework for medical and surgical discussions of hepatic anatomy and were essential for the advancement of modern medicine. In this article, the authors review the normal anatomy and physiology of the liver with a view to enhancing the clinician's knowledge base. They also provide a convenient model to assist with understanding and discussion of liver anatomy.
Patients with a history of an ACS who develop a recurrence represent a challenging clinical scenario with limited options for surgical repair. A PCS/TAR hernia repair achieves acceptable outcomes and may in fact be the best approach available.
The robotic surgical platform is being utilized by a growing number of hospitals across the country, including academic medical centers. Training programs are tasked with teaching their residents how to utilize this technology. To this end, we have developed and implemented a robotic surgical curriculum, and share our initial experience here. Our curriculum was implemented for all General Surgical residents for the academic year 2014-2015. The curriculum consisted of online training, readings, bedside training, console simulation, participating in ten cases as bedside first assistant, and operating at the console. 20 surgical residents were included. Residents were provided the curriculum and notified the department upon completion. Bedside assistance and operative console training were completed in the operating room through a mix of biliary, foregut, and colorectal cases. During the fiscal years of 2014 and 2015, there were 164 and 263 robot-assisted surgeries performed within the General Surgery Department, respectively. All 20 residents completed the online and bedside instruction portions of the curriculum. Of the 20 residents trained, 13/20 (65 %) sat at the Surgeon console during at least one case. Utilizing this curriculum, we have trained and incorporated residents into robot-assisted cases in an efficient manner. A successful curriculum must be based on didactic learning, reading, bedside training, simulation, and training in the operating room. Each program must examine their caseload and resident class to ensure proper exposure to this platform.
Background: Crohn's disease (CD) patients are typically underweight; however, a growing cohort of overweight CD patients is emerging. The current study investigates whether body mass index (BMI) or volumetric fat parameters can be used to predict morbidity after ileocolectomy for CD. Methods: One hundred and forty-three CD patients who underwent elective ileocolectomy were identified from our Inflammatory Bowel Disease (IBD) Registry. Patient demographics and operative outcomes were recorded. Visceral (VA) and subcutaneous (SA) adiposity and abdominal circumference (AC) were analyzed on preoperative CT scans using Aquarius iNtuition software. A visceral/subcutaneous ratio (VSR) was calculated. Results: BMI correlated with SA (p = 0.0001), VA (p = 0.0001) and AC (p = 0.0001) but not VSR (p > 0.05). BMI, VA and AC did not predict surgical morbidity (p > 0.05). In multivariate regression analysis, family history of IBD (p = 0.009), high American Society of Anesthesiologists score (p = 0.02) and increased VSR (p = 0.03) were independent predictors of postoperative morbidity. Conclusions: The visceral/subcutaneous fat ratio is a more reliable predictor of postoperative outcomes in CD patients undergoing ileocolectomy than conventional adiposity markers such as BMI. Preoperative calculation of the visceral/subcutaneous fat ratio offers the opportunity to optimize high-risk surgical patients, thus improving outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
