PURPOSE: To show the benefit of three-dimensional (3D) reconstructions of preoperative imaging for surgical performance. METHODS: A laparoscopic training environment with 15 hidden lymph nodes was designed. Three of them were marked with radiographic contrast agent and were only distinguishable from unmarked nodes via CT imaging. Thirty-six surgeons were divided into two groups. To group 1 the unprocessed CT data were shown. Group 2 was additionally shown a 3D reconstruction of the anatomy...

INTRODUCTION: Achalasia is a rare disorder in children who are commonly treated by laparoscopic Heller's myotomy (LHM). However, there are no large studies evaluating the results of LHM in the pediatric population, and the need of a concomitant fundoplication remains unclear. The aim of the study is to appraise the results of LHM based on a systematic literature review. MATERIALS AND METHODS: MEDLINE search of the English literature was performed for "achalasia," "children," "laparoscopy," "Heller," "myotomy," and "cardiomyotomy...

Endoscopic mucosal resection (EMR) is an increasingly popular minimally invasive technique that is used for the management of superficial lesions in the upper and lower gastrointestinal tract. The goal of this article is to describe the indications and technique of EMR, with a focus on the endoscopic management of Barrett's esophagus (BE). The two major EMR techniques-cap EMR and band EMR-will be presented, along with a discussion of their efficacy as well as their integration into the broader treatment paradigm of endoscopic eradication therapy for BE...

BACKGROUND: Robot-assisted transaxillary thyroidectomy (RATT) is an emerging technique with excellent cosmetic results but is supposedly more invasive and painful than conventional thyroidectomy (CT). This prospective study compared pain after RATT and CT. METHODS: Inclusion criteria were a nodule <5 cm and volume <30 mL. Patients received the same analgesia. Pain was evaluated by visual analog scale (VAS) in the recovery room (VASrr), on the first postoperative day at 8:00 a...

BACKGROUND: Recent evidence suggests that elevated intra-abdominal pressure (IAP) may adversely affect the intestinal barrier function. Toll-like receptor 4 (TLR-4) is responsible for the recognition of bacterial endotoxin or lipopolysaccharide and for initiation of the Gram-negative septic shock syndrome. The objective of the current study was to determine the effects of elevated IAP on intestinal bacterial translocation (BT) and TLR-4 signaling in intestinal mucosa in a rat model. METHODS: Male Sprague-Dawley rats were randomly assigned to one of two experimental groups: sham animals (Sham) and IAP animals who were subjected to a 15 mmHg pressure pneumoperitoneum for 30 minutes...

INTRODUCTION: Few studies have assessed the impact of obesity on laparoscopic cholecystectomy (LC) in pediatric patients. MATERIALS AND METHODS: Children who underwent LC were identified from the 2012 to 2013 American College of Surgeons' National Surgical Quality Improvement Program Pediatrics data. Patient characteristics, operative details, and outcomes were compared. Multivariable logistic regression was utilized to identify predictors of increased operative time (OT) and duration of anesthesia (DOAn)...

With the introduction of laparoscopy, the outcomes of patients undergoing paraesophageal hernia repair have improved dramatically. When the fundamentals of a proper repair are followed, patients can expect to have improvement in gastroesophageal reflux symptoms, including heartburn, regurgitation, chest pain, dysphagia, and dyspnea. Adhering to these principles will alleviate patients' symptoms and avoid reoperation. This article describes the approach to paraesophageal hernia repair, including patient evaluation, operative technique, and postoperative management...

INTRODUCTION: Use of a Fogarty catheter for emergent occlusion of tracheoesophageal fistulas (TEFs) has been described for use in unstable neonates. Our purpose was to describe a case series of elective Fogarty catheter occlusion of the TEF. MATERIALS AND METHODS: A formal operative laryngoscopy and rigid bronchoscopy were performed with Fogarty catheter placement into the fistula before surgical intervention. The balloon was inflated and gentle traction provided occlusion of the tract...

BACKGROUND: Enhanced recovery programs have become an important focus of perioperative management. A few studies have demonstrated the efficacy of an enhanced recovery after surgery (ERAS, which includes optimized pain control, restricted I.V. fluids, early initiation of postoperative oral feeding, and enforced mobilization) protocol in patients undergoing radical gastrectomy. We investigated the feasibility and safety of laparoscopic radical gastrectomy within ERAS programs. METHODS: In this single-center prospective randomized controlled trial conducted between September 2013 and August 2014, 149 consecutive locally advanced gastric cancer patients (T2-4, any N, M0) diagnosed by the CT scanning were allocated to either ERAS group (N = 73) or conventional pathway group (N = 76)...

As the field of minimally invasive surgery rapidly evolves, there is an opportunity to adopt innovative techniques to accommodate a variety of patient populations. In patients with portal hypertension, a major risk factor upon entry into the abdomen is injury to large, engorged paraumbilical vessels in the anterior abdominal wall. Major blood loss often results from just entering the abdomen. Here, we describe a patient with caput medusae secondary to portal hypertension presenting for laparoscopic repair of a ventral hernia...

In the last three decades, with the advancement of laparoscopic and thoracoscopic surgery, minimally invasive approaches for benign and malignant diseases of the esophagus have been developed and more experience is starting to accumulate across the world. Minimally invasive esophagectomy (MIE) has demonstrated acceptable lymph node retrieval, good postoperative outcomes, and low mortality. In this article, we review our preferred technique of MIE for adenocarcinomas of the gastroesophageal junction and distal esophagus...

The prevalence of gastroesophageal reflux disease (GERD) has mirrored the increase in obesity, and GERD is now recognized as an obesity-related comorbidity. There is growing evidence that obesity, specifically central obesity, is associated with the complications of chronic reflux, including erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. While fundoplication is effective in creating a competent gastroesophageal junction and controlling reflux in most patients, it is less effective in morbidly obese patients...

INTRODUCTION: Diagnostic laparoscopy is well accepted in the management of penetrating abdominal trauma (PAT). Therapeutic laparoscopy, on the other hand, remains controversial. In patients with multiple hollow viscera injuries, laparoscopy is usually converted to laparotomy. We aim at describing the laparoscopic-assisted technique in the management of patients with PAT. Using our experience with laparoscopy, we tailored the technique to the setting of PAT. METHODS: The laparoscopic-assisted approach (LAA) was adapted to a trauma setting and prospectively evaluated...

PURPOSE: Thoracoscopic esophageal atresia/tracheoesophageal fistula (EA/TEF) repair in neonates is technically difficult because of the small working space and fragility of tissues. This study aimed to show the construct validity of the neonatal EA/TEF simulator by video-based assessment of endoscopic suturing skill. MATERIALS AND METHODS: A rapid-prototyped neonatal chest model with an artificial esophagus model similar to the actual neonatal esophagus was developed...

Gastroesophageal reflux disease affects almost 20% of the population in the United States. Today, proton pump inhibitors are the most frequently prescribed drugs, with an estimated cost of 10 billion dollars per year. Although these medications control heartburn in the majority of patients, other symptoms such as regurgitation and respiratory symptoms often are not controlled, particularly in patients with large hiatal hernias. In these patients a properly performed laparoscopic fundoplication controls esophageal and extraesophageal symptoms and avoids life-long medical therapy...
