Endolumenal gastro-gastrostomy for astomia complicating Roux-En-Y Gastric Bypass.
A 45 year old female underwent an uncomplicated laparoscopic (divided) gastric bypass with circular stapled gastro-jejunostomy. Two years later, she developed a marginal ulcer which perforated and was treated with open Graham patch repair. Within 2 weeks post operatively, she developed progressive dysphagia. EGD and UGIS revealed a tight anastamotic stricture not amenable to dilation.… Continue Reading

Endoscopic Endoluminal Radiofrequency Ablation of Barrett\’s Esophagus: Initial Results and Lessons Learned
Background: Ablating Barrett’s epithelium may reduce the risk of developing esophageal adenocarcinoma. This study reports the initial experience of a single surgeon using an endoscopic endoluminal device delivering radiofrequency energy (the BARRx device) in ablating Barrett’s esophagus.Methods: All patients who underwent ablation of Barrett’s epithelium with the BARRx system were reviewed for length of Barrett’s… Continue Reading

Endoscopic Gastrojejunostomy Using the Full Thickness Plications
Objectives: Natural Orifice Translumenal Endoscopic Surgery (NOTES) utilizes resectional or anastomotic techniques. Anastomotic work to date is limited to suturing and stapling devices. Endoscopic gastrojejunostomy has been reported in two animal studies. The aim of our study is to assess feasibility of gastrojejunostomy with full thickness plications.Methods: Six ex vivo porcine stomachs were prepared with… Continue Reading

Endoscopic Transgastric Peritoneoscopy for Intestinal Ischemia in a Porcine Model
INTRODUCTIONIntestinal ischemia is difficult to diagnose in a critically ill patient. Natural orifice transluminal peritoneoscopy may provide us with a valuable diagnostic tool that can be performed at the bedside with minimal equipment requirements with a potential for a high sensitivity in detecting ischemic bowel. The aim of this study is to develop a bowel… Continue Reading

Evaluation of a Novel Air Seal Access Port for Transvaginal NOTES Cholecystectomy
Introduction: We previously reported successful transvaginal NOTES cholecystectomy in porcine models but experienced difficulty with pneumoperitoneum gas leakage when Magnetic Anchoring and Guidance System (MAGS) and endoscopic instruments were used in conjunction with conventional trocar seals. The purpose of this study was to evaluate the utility of a novel access port for this procedure.Methods: Non-survival… Continue Reading

Feasibility of Endoscopic Transgastric (ETGN) and Transvaginal (ETVN) Nephrectomy in the Porcine Animal Model.
BACKGROUND: Prior studies demonstrate the feasibility of NOTES organ resection. Aim of this study was to develop an endoscopic minimally-invasive resection of the kidney. METHODS: Using an endoscopic transgastric (N=2) and transvaginal (N=4) approach, resection of the kidney was performed in the porcine animal model. RESULTS: Six female swine underwent endoscopy with a double-channel gastroscope.… Continue Reading

Feasibility of NOTES in a Porcine Model for Lysis of Adhesions and Appendectomy
Introduction: Appendectomy and small bowel enterolysis for adhesions are commonly performed general surgical procedures. Our lab aimed to assess the feasibility of natural orifice translumenal endoscopic surgery (NOTES) for appendectomy and lysis of adhesions (LOA) using a live porcine model.Methods: The bicornuate uterus of the female swine has been used previously as a model for… Continue Reading

First experience of human NOTES in Ukraine: Transvaginal and transumbilical rendezvous cholecystectomy
Introduction. The biggest problem for safeness of NOTES is the great possibility of contamination spreading from natural orifice into the peritoneal cavity. Currently transvaginal approach seems to be the simplest in access and wound closure. Thus, the aim of our study was evaluation of peritoneal contamination and adhesions formation after transvaginal and transumbilical rendezvous approach… Continue Reading

Full thickness excision of T1 rectal cancer with transanal endoscopic microsurgery
Background: Transanal endoscopic microsurgery is a useful method for the local excision of polyps and selected rectal cancers. The standardization of the technique for this procedure is likely to be important for preventing local recurrence. This video demonstrates the standard procedure of TEM in a patient with a 5cm rectal polyp. Methods: The patient was… Continue Reading

Gastrotomies Do Not Require Repair Following Transgastric Instrumentation: A Controlled Study
Introduction: The optimal method for closing gastrotomies following transgastric instrumentation has yet to be found. Our center has previously validated the use of a bioabsorbable plug for this purpose. The goal of this study was to compare gastrotomy closure, in a canine model, between animals left to heal without treatment and those treated with endoscopically… Continue Reading

Histological Aspects of the Healing of a Gastrotomy in Different Gastric Regions.
BACKGROUND. The endoscopic transgastric technique is increasingly gaining popularity among surgeons and gastroenterologists. Factors that could potentially limit the use of the gastric lumen to endoscopically access the intra-abdominal cavity have not been fully investigated. The gastric chamber is a complex organ, physiologically and anatomically. The healing process of the gastric wall following a transgastric… Continue Reading

How Can Inadvertent Intestinal Insufflation Be Limited in Complex Intragastric NOTES Procedures?
Objective: Early experience with transgastric NOTES in animal models have demonstrated the consequences of inadvertent insufflation of the small and large bowel. The resultant crowding of the intestines increases the risk of ensnaring the bowel during transgastric suturing. A mechanism for limiting transpyloric insufflation but permitting the necessary intragastric working space is needed.Description: A NOTES… Continue Reading

Human Transvaginal Cholecystectomy using an IT-Knife
Background: NOTES is an evolving and controversial field of surgery on its beginning. Laparoscopic surgery and Endoscopy merges to fulfill it. Despite NOTES human experience had begin by the transgastric way with Rao in India, the transvaginal approach is taking place as a safer and easy way to achieve the upper abdomen. As on its… Continue Reading
