Background: Esophageal dysmotility is a common finding in patients being evaluated for antireflux surgery, although its implication remains unclear. We aimed to evaluate outcomes of patients with esophageal dysmotility after fundoplication.
Methods: A retrospective review of a prospective quality-database was performed.
Background: Surgical treatment options of gastroesophageal reflux disease have changed significantly in the last 50 years. Magnetic Sphincter Augmentation (MSA) and Anti-reflux Mucosectomy (ARMs) are gaining traction but there is a paucity of literature comparing these novel options to Toupet fundoplication and gold standard Nissen fundoplication.
Methods: This is a retrospective review of a prospectively maintained database, evaluating patients undergoing Nissen, Toupet, MSA, and ARMs.
Background And Aims: A small percentage of patients with esophageal dysmotility disorders (EDDs) fail to improve or relapse after management by laparoscopic Heller myotomy (LHM) and peroral endoscopic myotomy (POEM). In this study, we aimed to describe the role of functional luminal imaging probe (FLIP) in identifying patients who might benefit from lower esophageal sphincter (LES)-directed retreatment.
Methods: This was a retrospective study at 6 tertiary care centers (United States, 4; Europe, 1; Asia, 1) between January 2015 and April 2021 involving patients with prior failed myotomy.
Importance: Posttraumatic stress disorder (PTSD) is a prevalent and serious mental health problem. Although there are effective psychotherapies for PTSD, there is little information about their comparative effectiveness.
Objective: To compare the effectiveness of prolonged exposure (PE) vs cognitive processing therapy (CPT) for treating PTSD in veterans.
Article Synopsis
- - A structured curriculum for the Critical View of Safety was implemented to help prevent bile duct injuries during laparoscopic cholecystectomy, showing immediate improvement in surgeons' practices.
- - One year post-curriculum, while overall scores remained better than before the training, a decline in retention of knowledge was observed, indicating some loss of skills over time.
- - Acute care surgeons demonstrated significantly lower retention of Critical View of Safety skills compared to general and minimally invasive surgeons, highlighting the need for ongoing education in this area.
Introduction: The esophagogastric junction (EGJ) is a complex anti-reflux barrier whose integrity relies on both the intrinsic lower esophageal sphincter (LES) and extrinsic crural diaphragm. During hiatal hernia repair, it is unclear whether the crural closure or the fundoplication is more important to restore the anti-reflux barrier. The objective of this study is to analyze changes in LES minimum diameter (D) and distensibility index (DI) using the endoluminal functional lumen imaging probe (FLIP) during hiatal hernia repair.

We present a simulation-based curriculum using an "into the fire" approach with hands-on pre- and post-tests to teach the use of this technology. The curriculum consists of a series of pre-tests, didactic content, mentored hands-on instructions, and post-tests.

We report a single institutional experience in performing hernia repair with mesh in terms of hernia-specific outcomes, mesh-related complications, and patient-reported quality of life.
Study Design: Patients who underwent abdominal wall hernia repair with mesh at a single institution were identified from a prospectively maintained quality database.
Background: The endoluminal functional lumen imaging probe (FLIP) can be used to obtain real-time measurements of the diameter (D), cross-sectional area (CSA), and distensibility of the pylorus before and after peroral pyloromyotomy (POP), an emerging endoscopic treatment for delayed gastric emptying. Our study aims to report our single-center experience in performing POP with FLIP measurements before and after pyloromyotomy.
Methods: A retrospective review of a prospectively maintained gastroesophageal database was performed.
Background: Anti-reflux mucosectomy (ARMS) is a new endoscopic procedure involving a hemi-circumferential endoscopic mucosal resection (EMR) around the gastroesophageal junction. We aim to compare perioperative and quality of life outcomes of patients with reflux who underwent ARMS to a comparable group who underwent laparoscopic Nissen fundoplication (NF).
Methods: A retrospective review of a prospectively maintained quality database was performed.
Background: Peroral endoscopic myotomy (POEM) has previously been shown to be equally if not more expensive than laparoscopic Heller myotomy (LHM). We compare perioperative outcomes and charges between POEM and LHM at a single institution.
Methods: Outcomes and charge data of 33 patients who underwent LHM and 126 patients who underwent POEM were analyzed.
Background: Peroral endoscopic pyloromyotomy, or gastric peroral endoscopic myotomy, is a novel endoscopic procedure for the treatment of refractory gastroparesis. We present a simulation-based curriculum using an "into-the-fire" approach with hands-on pre- and post-tests to teach this procedure.
Methods: Six, 1-day peroral endoscopic pyloromyotomy courses were taught by an expert surgical endoscopist in 2018 to 2019.
Introduction: The Endoluminal Functional Lumen Imaging Probe (Endoflip) can be used to provide objective measurements of the gastroesophageal junction during fundoplication, and recent publications have suggested that this device could improve surgical outcomes. However, the impact of operative variables has not been clearly reported. The aim of this study is to determine the effect of these variables on functional lumen imaging probe (FLIP) measurements.
View Article and Find Full Text PDFBackground: The functional lumen imaging probe is a balloon-based catheter that can be used as a bougie during fundoplication. Our goal was to compare the short-term, quality-of-life outcomes and esophageal-injury rate after fundoplication over a functional lumen imaging probe compared to a traditional bougie.
Methods: This is a retrospective review of a quality database at a single center.
Introduction: Peroral endoscopic myotomy (POEM) is a minimally invasive treatment for achalasia. Considerable evidence demonstrates a high incidence of gastroesophageal reflux disease (GERD) after POEM. The endoluminal functional lumen imaging probe (FLIP) uses impedance planimetry to obtain objective measurements of the gastroesophageal junction.
View Article and Find Full Text PDFBackground: Although peroral endoscopic myotomy (POEM) has emerged as a highly efficacious procedure in the treatment of a variety of esophageal motility disorders, currently no standard pathway for postprocedural care exists. Our study aims to report institutional outcomes in performing POEM as an outpatient procedure with same-day discharge. Additionally, we seek to determine factors associated with admission.

Methods: A retrospectively collected database of Barrett's esophagus (BE) patients spanning a 16-year period was queried. Patients who progressed from NDBE to HGD or EAC were identified and compared to patients who did not.
Background & Aims: Endoscopic submucosal dissection (ESD) is a widely accepted treatment option for superficial gastric neoplasia in Asia, but there are few data on outcomes of gastric ESD from North America. We aimed to evaluate the safety and efficacy of gastric ESD in North America.
Methods: We analyzed data from 347 patients who underwent gastric ESD at 25 centers, from 2010 through 2019.
Introduction: The Endoluminal Functional Lumen Imaging Probe (Endoflip™) is a balloon-based catheter that provides real-time, objective feedback regarding the distensibility of any sphincter in the gastrointestinal tract. Usage of the Functional Lumen Imaging Probe (FLIP) has not been standardized, which has limited the interpretation and generalizability of published data. The purpose of this consensus statement is to provide a standardized protocol for obtaining FLIP measurements in order to create a more uniform approach to data collection.
View Article and Find Full Text PDFBackground: We provide a comprehensive report of our institution's experience with the endoluminal functional lumen imaging probe (Endoflip) impedance planimetry system, a device that can be used intraoperatively to objectively evaluate the distensibility of any sphincter of the gastrointestinal tract. We aim to describe the variety of ways in which the Endoflip can be used in a foregut surgeon's practice.
Study Design: This is a retrospective review of a prospectively maintained quality database of all patients in which the functional lumen imaging probe (FLIP) system was used between February 2013 and June 2019.
Background: The functional lumen imaging probe (FLIP) is an innovative tool that uses impedance planimetry to assess esophageal geometry in real time. It has been used to diagnose achalasia and evaluate treatment failure after laparoscopic Heller myotomy (LHM) and peroral endoscopic myotomy (POEM). We hypothesize that impedance planimetry can be utilized intra-operatively to assess adequacy of myotomy and assist in predicting patient outcomes.

Methods: This is a retrospective review of patients who underwent a procedure with the endoscopic suturing system between April 2010 and March 2019. Definitions of technical and clinical success were established for each application.
Introduction: We hypothesized that practicing surgeons would successfully achieve a better and more frequent Critical View of Safety (CVS) during laparoscopic cholecystectomy (LC) after participation in a structured Safe CVS Curriculum.
Methods: All surgeons performing LC at a regional health system had four LC cases recorded: twice before and twice after a curriculum focused on the CVS, which was led by a member of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Safe LC Task Force. Videos were then de-identified and randomly ordered for grading on a 6-point CVS assessment tool by two expert surgeons, who were blinded to the operator and whether the surgeries were performed before or after the curriculum.
Background: For many surgeons, a prior prostatectomy is considered a contraindication to laparoscopic totally extraperitoneal hernia repair. This study aims to evaluate the safety, efficacy, and efficiency of totally extraperitoneal in these patients.
Methods: This is a review of a prospectively collected hernia database evaluating patients who underwent totally extraperitoneal repair between October 2009 and March 2018.
