Preoperative high respiratory quotient correlates with lower weight loss after bariatric surgery.

Background: The respiratory coefficient (RQ), as determined by indirect calorimetry (IC), classifies diet as being carbohydrate rich (RQ = 0.7-0.8), fat rich (RQ = 0.

Clinical Assessment of a Biofilm-disrupting Agent for the Management of Chronic Wounds Compared With Standard of Care: A Therapeutic Approach.

Objective: The authors study the use of a biofilm-disrupting wound gel designed for wound management to determine if disrupting chronic wound biofilm would be therapeutically efficacious.

Materials And Methods: This prospective, randomized, open-label clinical trial was performed from September 2014 through March 2016. Forty-three patients (22 experimental, 21 control) with chronic, recalcitrant wounds were randomized to a 12-week treatment with a biofilm-disrupting wound gel (experimental) or a broad-spectrum antimicrobial ointment (control).

Endoscopic and surgical management of nonampullary duodenal neoplasms.

Background: Sporadic nonampullary duodenal neoplasms (SNADN) can have malignant potential for which endoscopic and surgical resections are offered. We report combined gastroenterologic and surgical experience for treatment of SNADN, including endoscopic mucosal resection (EMR) and pancreas-preserving partial duodenectomy (PPPD).

Methods: We retrospectively reviewed 121 consecutive patients, who underwent 30 PPPDs and 91 EMRs for mucosal and submucosal SNADN.

Pancreatic Surgery in the Older Population: A Single Institution's Experience over Two Decades.

. Surgery is the most effective treatment for pancreatic cancer. However, present literature varies on outcomes of curative pancreatic resection in the elderly.

Introduction of mechanical sphincter augmentation for gastroesophageal reflux disease into practice: early clinical outcomes and keys to successful adoption.

Background: A new device for mechanical sphincter augmentation (MSA) of the lower esophageal sphincter was approved by the FDA on March 22, 2012. We report early experience with MSA, specifically addressing postoperative management.

Study Design: Between October 1, 2011 and June 1, 2013, 150 patients were evaluated for MSA.

Variability of NSQIP-assessed surgical quality based on age and disease process.

Background: Recent national attention has focused on improving upon the surgical quality of hospitals across the United States. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database includes expected morbidity probability for each surgical patient. We sought to investigate the accuracy of this probability across the spectrum of general surgical operations and assess the variability based on the age and disease process.

National trends in resection of the distal pancreas.

Aim: To investigate national trends in distal pancreatectomy (DP) through query of three national patient care databases.

Methods: From the Nationwide Inpatient Sample (NIS, 2003-2009), the National Surgical Quality Improvement Project (NSQIP, 2005-2010), and the Surveillance Epidemiology and End Results (SEER, 2003-2009) databases using appropriate diagnostic and procedural codes we identified all patients with a diagnosis of a benign or malignant lesion of the body and/or tail of the pancreas that had undergone a partial or distal pancreatectomy. Utilization of laparoscopy was defined in NIS by the International Classification of Diseases, Ninth Revision correspondent procedure code; and in NSQIP by the exploratory laparoscopy or unlisted procedure current procedural terminology codes.
