BACKGROUND: Histological analysis of surgical specimen is the gold standard for cancer classification. In particular, frozen histological diagnosis of vague peritoneal spots or uncertain excision of tumors plays a crucial role in the decision to proceed with or abandon an operation. Confocal laser microscopy (CLM) enables in-vivo and real-time high-resolution tissue analysis. This method has already been used during endoscopic assessments analyzing transformation of esophageal or colon mucosa...

BACKGROUND: Optimal treatment for symptomatic patients with non-achalasia motility disorders (NAD) such as diffuse esophageal spasm, esophagogastric junction outlet obstruction, and hypercontractile disorder is not well established. POEM has been offered to these patients since it is a less invasive and less morbid procedure but long-term outcomes remain undetermined. The aim of this study was to assess long-term outcomes of POEM for patients with NAD. METHODS: Records of 40 consecutive patients undergoing POEM for NAD from May 2011 to January 2016 at a single center were retrospectively reviewed...

BACKGROUND: Randomized controlled trials have demonstrated that bariatric surgery is effective in obtaining remission of type 2 diabetes mellitus (T2DM) in obese patients, yet no data exist in the literature from prospective studies with ileal interposition with duodenal diversion sleeve gastrectomy (II-DD-SG). The aim of this case-control study is to investigate if II-DD-SG is superior to medical treatment in T2DM obese patients. METHODS: Thirty obese patients (BMI > 30) affected by T2DM were recruited for surgery (II-DD-SG) between 2008 and 2011 and were matched with an equal control group which received standard medical treatment...

BACKGROUND: Although single-port laparoscopic cholecystectomy (SILC) is safe and effective, inherent surgeons' discomfort has prevented a large-scale adaptation of this technique. Recent advances in robotic technology suggest that da Vinci Single-Site™ cholecystectomy (dVSSC) may overcome this issue by reducing the stress load of the surgeon compared to SILC. However, evidence to objectively assess differences between the two approaches is lacking. METHODS: 60 patients [36 women, 24 men (mean age 52 years)] with benign gallbladder disease were randomly assigned to dVSSC (n = 30) or SILC (n = 30) in this single-centre, single-blinded controlled trial...

INTRODUCTION: Surgical rating scales (SRSs) enable the surgeon to uniformly quantify surgical working conditions. They are increasingly used as a primary outcome in studies evaluating the effect of anaesthesia or surgery-related interventions on the quality of the surgical work field. SRSs are especially used in laparoscopic surgery due to a renewed interest in deep neuromuscular block. There are however no guidelines regarding the uniform use of SRS and the uniform reporting of results...

BACKGROUND: The (99m) technetium-labelled hepato imino diacetic acid (HIDA) scan is widely used to evaluate patients with biliary colic with a normal trans-abdominal ultrasound scan. Most studies recommend cholecystectomy for patients with biliary dyskinesia, defined by gallbladder ejection fraction (GBEF) of less than 35-40% on HIDA scan. There are no recommendations regarding management of hyperkinetic gallbladder defined by GBEF of greater than 80% on HIDA scan. The aim of our study was to evaluate the outcomes following cholecystectomy on patients with biliary colic associated with hyperkinetic gallbladder...

INTRODUCTION: Diagnostic laparoscopy (DL) is an increasingly used modality when approaching penetrating abdominal trauma (PAT). Trauma surgeons can utilize this minimally invasive technique to quickly assess for injury in hemodynamically stable patients. DL with a confirmed injury can be repaired through therapeutic laparoscopy (TL) or conversion to exploratory laparotomy (EL). This study analyzes the use of laparoscopy as a first-line therapy for hemodynamically stable patients with PAT...

BACKGROUND: Mental training of laparoscopic procedures with E-learning has been shown to translate to the operating room. The present study aims to explore whether the use of checklists during E-learning improves transfer of skills to the simulated OR on a Virtual Reality (VR) trainer for Roux-en-Y gastric bypass (RYGB). METHODS: Laparoscopy naive medical students (n = 80) were randomized in two groups. After an E-learning introduction to RYGB, checklist group rated RYGB videos using the validated Bariatric Objective Structured Assessment of Technical Skills (BOSATS) checklist while group without checklist only observed the videos...

BACKGROUND: Complete mesocolic excision (CME) is advocated based on oncologic superiority, but not commonly performed in North America. Many data are case series with few comparative studies. Our aim was to perform a systematic review comparing outcomes between CME and non-CME colectomy. METHODS: A systematic review was performed according to PRISMA guidelines of MEDLINE, EMBASE, HealthStar, Web of Science, and Cochrane Library. Studies were included if they compared conventional resection (non-CME) to CME for colon cancer...

BACKGROUND: Outcomes are not well studied in patients undergoing remediation for multi-fundoplication failure, that is, two or more prior failed fundoplications. Re-operation must balance reflux control and restoration of the ability to eat with the challenge of reconstructing a distorted hiatus and GE junction. The purpose of this study is to present our experience with surgical remediation for multi-fundoplication failure. METHODS: Medical records were retrospectively reviewed of 91 patients who underwent third time or more esophagogastric operation for fundoplication failure at a single institution from 2007 to 2016...
