Small bowel neuroendocrine tumors (SBNETs) are often indolent, but occasionally, patients present with acute symptoms requiring emergent operative intervention. Our aim was to determine whether emergency surgery for SBNETs affects long-term outcomes. An institutional database was reviewed to identify patients with SBNET diagnosed between 1990 and 2015. Need for emergency resection (ER) was compared with elective resection (ELR). One hundred and thirty-four patients met inclusion criteria. Median age was 59 years (range, 21-91), and median tumor size was 1...

We have recently introduced laparoscopic magnetic sphincter augmentation (MSA) combined with hiatal hernia repair for treatment of patients with medically refractory gastroesophageal reflux disease (GERD). MSA is a novel surgical approach to the treatment of severe GERD, in which magnetic beads are secured around the lower esophageal sphincter, augmenting the lower esophageal sphincter function as an anti-reflux barrier. We hypothesize that patients undergoing MSA will achieve GERD relief, equal to that obtained after laparoscopic Nissen fundoplication...

BACKGROUND: Spinal cord stimulation (SCS) relieves pain by delivering doses of electric current to the dorsal column of the spinal cord and has been found to be most effective in the treatment of neuropathic pain. Psychological distress is a significant risk factor for the development of chronic pain and has been found to affect the outcome of SCS. Childhood trauma is a risk factor for chronic pain, but has not previously been studied in SCS patients. OBJECTIVES: The objective of this prospective registry-based study was to investigate the prevalence of 5 domains of childhood trauma (emotional neglect, emotional abuse, physical neglect, physical abuse, and sexual abuse) and their relationship with the outcome of spinal cord stimulation on patients suffering from treatment-resistant chronic pain...

BACKGROUND: Laparoscopic fundoplication is the gold standard operation for treatment of gastroesophageal reflux disease (GERD). It has been suggested that persistent postoperative dysphagia is increased following Nissen fundoplication compared to partial fundoplication. This study aimed to determine risk factors for persistent postoperative dysphagia, specifically examining the type of fundoplication. METHODS: Patients experiencing GERD symptoms who underwent laparoscopic Nissen, Toupet, or Dor fundoplication from 2009 to 2016 were identified from a single-institutional database...

BACKGROUND: Operative skills correlate with patient outcomes, yet at the completion of training or after learning a new procedure, these skills are rarely formally evaluated. There is interest in the use of summative video assessment of laparoscopic benign foregut and hiatal surgery (LFS). If this is to be used to determine competency, it must meet the robust criteria established for high-stakes assessments. The purpose of this review is to identify tools that have been used to assess performance of LFS and evaluate the available validity evidence for each instrument...

BACKGROUND: Quality of life (QOL) is an important outcome measure after ventral hernia repair (VHR). The Hernia-Related QOL Survey (HerQLes) is a specific survey tool for QOL after VHR. Studies comparing QOL in patients with biologic mesh repairs (BMRs) and synthetic mesh repairs (SMRs) are lacking. STUDY DESIGN: A survey based on the HerQLes was administered via e-mail to 974 patients who had undergone VHR at Stanford Medical Center. From 175 patients who were included in the study, the mean HerQLes scores and postoperative complications were compared between patients with suture repairs (SR), BMR, SMR, with and without component separation, and different types of SMR...

BACKGROUND: The Single Port Orifice Robotic Technology (SPORT) Surgical System by Titan Medical Inc. is designed to overcome the inherent challenges of minimally invasive single-access procedures. The aim of this preclinical study was to evaluate the feasibility of various digestive surgery procedures using this novel surgical robotic platform. METHODS: A total of 12 minimally invasive procedures were performed on six pigs (5 cholecystectomies, 3 Nissen fundoplications, 1 splenectomy and 1 hepatic pedicle dissection) and on one human cadaver (1 cholecystectomy and 1 Nissen fundoplication), by four laparoscopic surgeons...

PURPOSE: Nissen fundoplication (NF) is commonly performed in children with gastro-esophageal reflux disease (GERD). Patients undergoing NF often have co-morbidities. Reported outcomes of NF vary considerably. This study investigated which factors might predict multiple readmissions or death in the first year following NF at our institution. METHODS: A retrospective chart review of 187 children who underwent NF at our institution between January 2004 and December 2015 was undertaken...

BACKGROUND: Laparoscopic hiatal hernia repair via Toupet or Nissen fundoplication remains the most commonly performed procedures for management of large hiatal hernia. Few studies have compared the procedures' long-term effectiveness. This study sought to characterize the efficacy of laparoscopic Toupet versus Nissen fundoplication for types III and IV hiatal hernia. METHODS: With IRB approval, a review of all laparoscopic hiatal hernia repairs with mesh reinforcement performed over 7 years at a single center by one surgeon was conducted...

BACKGROUND: Laparoscopic antireflux surgery is a standard surgical treatment method for gastroesophageal reflux disease (GERD) in Western countries. However, the procedure has not been actively carried out in Korea because of concerns regarding surgical complications. Here, we conducted this study to evaluate short-term surgical outcomes of laparoscopic Nissen fundoplication (LNF) performed at a single institution. METHODS: From January 2010 to August 2016, totally 29 patients underwent LNF for GERD performed by three surgeons at Asan Medical Center, Korea...

BACKGROUND: Current evidence to support cost effectiveness of doctor- pharmacist collaborative prescribing is limited. Our aim was to evaluate inpatient prescribing of venous thromboembolism (VTE) prophylaxis by a pharmacist in an elective surgery pre-admission clinic against usual care, to measure any benefits in cost to the healthcare system and quality adjusted life years (QALYs) of patients. METHOD: A decision tree model was developed to assess cost effectiveness of pharmacist prescribing compared with usual care for VTE prophylaxis in high risk surgical patients...

BACKGROUND: Although around 30% of patients with gastroesophageal reflux disease (GERD) are insufficiently treated with medical therapy, only 1% opt for surgical therapy. One of the reasons behind this multifactorial phenomenon is the described adverse effect of long-term dysphagia or gastric bloating syndrome after surgical treatment. Aim of this study was to evaluate the most common side effects associated with anti-reflux surgery, as well as long-term outcomes in a large cohort of highly surgically standardized patients after laparoscopic Nissen fundoplication (LNF)...

BACKGROUND: Mechanical knee symptoms are often considered important in the decision to perform knee arthroscopy on the suspicion of a meniscal tear. We investigated if presence of a meniscal tear at knee arthroscopy in adults is associated with presence of preoperative self-reported mechanical knee symptoms. METHODS: We used data from Knee Arthroscopy Cohort Southern Denmark (KACS). KACS consists of patients aged 18 years or older referred to knee arthroscopy on the suspicion of a meniscal tear at four recruiting hospitals between 1 February 2013 and 31 January 2015...

BACKGROUND: The symptoms of gastroesophageal reflux disease (GERD) are very common. Despite the fact that 40% of patients continue to suffer under conservative treatment, only approximately 1% of affected patients are operated on in Germany. Until recently, antireflux surgery was performed nearly exclusively in the form of a Nissen fundoplication or a Toupet hemifundoplication. These methods are still considered the gold standard. A new surgical minimally invasive procedure is described which treats reflux symptoms through electrical neuromodulation of the lower esophageal sphincter (LES)...

Objective: Epilepsy surgery results in seizure freedom in the majority of drug-resistant patients. To improve surgery outcome we studied whether MEG metrics combined with machine learning can improve localization of the epileptogenic zone, thereby enhancing the chance of seizure freedom. Methods: Presurgical interictal MEG recordings of 94 patients (64 seizure-free >1y post-surgery) were analyzed to extract four metrics in source space: delta power, low-to-high-frequency power ratio, functional connectivity (phase lag index), and minimum spanning tree betweenness centrality...
