Identifying hiatal hernia with impedance planimetry during esophageal distension testing

Dustin A. Carlson, Peter J. Kahrilas, Aditi Simlote, Edoardo Vespa, more

Neurogastroenterology & Motility > 35 > 2 > n/a - n/a

Introduction Functional luminal imaging probe (FLIP) Panometry evaluates the esophageal response to distension involving biomechanics and motility. We have observed that hiatus hernia (HH) is evident during FLIP studies as a separation between the crural diaphragm (CD) and lower esophageal sphincter (LES) like what is seen with high‐resolution manometry (HRM). The aim of this study was to compare...

Achalasia subtypes can be identified with functional luminal imaging probe (FLIP) panometry using a supervised machine learning process

Dustin A. Carlson, Wenjun Kou, Katharine P. Rooney, Alexandra J. Baumann, more

Neurogastroenterology & Motility > 33 > 3 > n/a - n/a

Background Achalasia subtypes on high‐resolution manometry (HRM) prognosticate treatment response and help direct management plan. We aimed to utilize parameters of distension‐induced contractility and pressurization on functional luminal imaging probe (FLIP) panometry and machine learning to predict HRM achalasia subtypes. Methods One hundred eighty adult patients with treatment‐naïve achalasia...

Abdominal Radiology > 2015 > 40 > 2 > 237-245

Natural orifice transluminal endoscopic surgery (NOTES) is a surgical technique that has been evolving rapidly. Endoscopic submucosal dissection was initiated in 1999, in Japan, for en-bloc resection of large lesions of the stomach (Zhou et al., World J Gastroenterol 19:6962–6968, 2013, ; Kobara et al., Clin Exp Gastroenterol 7:67–74, 2014). Since then, many additional therapies utilizing natural...

Emerging Techniques in Minimally Invasive Surgery. Pros and Cons

P. Marco Fisichella, Steven R. DeMeester, Eric Hungness, Silvana Perretta, more

Journal of Gastrointestinal Surgery > 2015 > 19 > 7 > 1355-1362

New trends have emerged regarding the best minimally invasive access approaches to perform gastrointestinal surgery. However, these newer approaches are seen critically by those who demand a more strict assessment of outcomes and safety. An international panel of expert gathered at the 2014 American College of Surgeons Meeting with the goal of providing an evidence-based understanding of the real...

rs4771122 Predicts Multiple Measures of Long-Term Weight Loss After Bariatric Surgery

Laura J. Rasmussen-Torvik, Abigail S. Baldridge, Jennifer A. Pacheco, Sharon A. Aufox, more

Obesity Surgery > 2015 > 25 > 11 > 2225-2229

We examined the association of 34 single nucleotide polymorphisms with weight loss up to 9.5 years after Roux-en-Y surgery. Participants were enrollees in the NUgene biobank with stored DNA and linked electronic health records. Ninety-five self-identified white participants underwent surgery and had follow-up weights obtained between 1 and 9.5 years after surgery. SNP rs4771122 was the variant most...

High failure rate of the laparoscopic-adjustable gastric band as a primary bariatric procedure

Tammy Kindel, Emily Martin, Eric Hungness, Alex Nagle

Surgery for Obesity and Related Diseases > 2014 > 10 > 6 > 1070-1075

Determinants of success of a bariatric procedure are many but paramount is the ability to durably produce significant and reliable weight loss. We sought to determine the primary success of the laparoscopic adjustable gastric band (LAGB) by defining failure as clinical weight loss failure with an intact band (excess weight loss [EWL]<20%) or band removal (terminal removal or conversion to a secondary...

Multicenter analysis of diaphragm pacing in tetraplegics with cardiac pacemakers: Positive implications for ventilator weaning in intensive care units

Raymond P. Onders, Saeid Khansarinia, Todd Weiser, Cynthia Chin, more

Surgery > 2010 > 148 > 4 > 893-898

Diaphragm pacing (DP) can replace mechanical ventilation in tetraplegics and in trials has assisted respiration in amyotrophic lateral sclerosis patients. This report describes results of DP in patients with cardiac pacemakers.Prospective, single-center and multicenter, nonrandomized, controlled, interventional protocols under U.S. Food and Drug Administration and/or institutional review board approval...

Administrative considerations when implementing ACS/APDS Skills Curriculum

Deborah Rooney, Carla Pugh, Edward Auyang, Eric Hungness, more

Surgery > 2010 > 147 > 5 > 614-621

With time and cost constraints, implementing an effective, yet efficient, skills curriculum poses significant challenges. Our purpose is to describe a successful curriculum administrative structure that promoted faculty buy-in and accountability, learner responsibility, and acceptable resource usage.A total of 14 American College of Surgery (ACS) modules were included in the postgraduate year 1 curriculum...

Outcome measures for surgical simulators: Is the focus on technical skills the best approach?

Carla Pugh, Stephen Plachta, Edward Auyang, Aurora Pryor, more

Surgery > 2010 > 147 > 5 > 646-654

Mastery of operative performance is based on technical skill and intra-operative judgment. However, previous simulation studies have largely focused on technical skills and measures. This study investigates changes in operative performance when assessment and feedback focus on decision making.Using a nonequivalent, pretest/post-test experimental design, 8 senior residents (PGY4-5) performed a laparoscopic...

Patient attitudes and expectations regarding natural orifice translumenal endoscopic surgery

Lee L. Swanstrom, Eric Volckmann, Eric Hungness, Nathaniel J. Soper

Surgical Endoscopy > 2009 > 23 > 7 > 1519-1525

Background Natural orifice translumenal endoscopic surgery (NOTES) has theoretical patient advantages. Because public attitude toward NOTES will influence its adoption, this study aimed to assess patients’ opinions regarding the NOTES procedure. Methods For this study, 192 patients were surveyed. Both NOTES and laparoscopic surgery (LS) are described together with an example case. Presurgical patients...

Mucosal and enterocyte IL-6 production during sepsis and endotoxemia - role of transcription factors and regulation by the stress response

Timothy Pritts, Eric Hungness, Quan Wang, Bruce Robb, more

The American Journal of Surgery > 2002 > 183 > 4 > 372-383

Background: Sepsis and endotoxemia are associated with increased production of interleukin-6 (IL-6) in gut mucosa. Mucosal IL-6 may regulate enterocyte acute phase protein synthesis and intestinal IgA production. In addition, increased IL-6 has been proposed to be a mechanism of loss of mucosal integrity in critical illness. The purpose of this review is to describe current knowledge of the regulation...
