“…However, with the introduction of the endoscope inside the abdominal cavity under direct vision, as extolled by the technique of natural orifice transluminal endoscopic surgery (NOTES) [34,35] , we were able to access those areas of extensive necrosis and to proceed with the debridement and necrosectomy, drainage and PEG placement [14] .…”

Introduction: Necrosectomy is the gold standard treatment for infected pancreatic necrosis (IPN). A percutaneous and endoscopic approach has been accepted in selected cases. Endoscopic drainage (ED) of IPN can be performed by using transpapillary or transmural procedures, or a combination of both with or without endoscopic ultrasound. Aims: The aim of this study was to determine the indications, complications, success rate, and the importance of assessment of main pancreatic duct integrity by endoscopic retrograde pancreatography (ERP) in patients with IPN. Methods: Records of all patients who underwent endoscopic necrosectomy from January 2002 to December 2007 at Rio de Janeiro Federal University Hospital were reviewed. A total of 56 patients were included. ED was performed using daily transmural and transpapillary drainage. A diagnostic pancreatogram (ERP) to search for communications between the pancreatic duct and the collection were performed in all cases and in cases where communication existed. A pre-cut needle knife was used to puncture the cyst wall, aspirate the content and then enter at the cyst cavity (contrast was injected to ensure opacification of the cyst and subsequent drainage). Sphincterotomy catheter or balloons were used to enlarge and ensure a wide cystoenterostomy. All patients were followed with computerized tomography scans or ultrasound to ensure clinical resolution. Mean follow-up was 21 months. Results: 49/56 patients could be successfully treated. ED was successful in 49 patients (87%) and in 3 (13%) it failed. Mean follow-up was 21 months. During this period, there were 2 (10.5%) pseudocyst recurrences and only 1 (5.2%) recurrence of new episodes of pancreatic necrosis, and all were managed clinically and/or endoscopically. No mortality was related to the procedure. Conclusion: ED with daily necrosectomy is a useful method to remove infected and sterile pancreatic necrosis.

“…Lymph nodes were grasped with a snare or standard endoscopic instruments and were retrieved from the abdominal cavity via the stomach and the esophagus. (Ryou et al 2007) performed combined transcolonic and transvaginal distal pancreatectomy in pigs. A prototype R-scope was introduced into the colon, the bowel wall was incised using a needle knife, and the R-scope was advanced into the peritoneal cavity.…”

“…The first reports described transcolonic peritoneoscopy [10,11] (n = 6) and cholecystectomy [12] (n = 5) in swine survival models with septic complications occu rring in 1 animal (9%) following incomplete closure of the anterior colotomy [12] . Subsequent reports have described transcolonic surgical procedures of increasing complexity such as ventral hernia repair [13] and distal pancreatectomy [14] in survival swine models with good results. The cited adv antages of the transrectal approach include the relative ease of colotomy creation and closure, and the ability to visualize abdominal organs in line with the endoscope without the need for retroflexion [13,14] .…”

All authors agree that the viability of this approach relies on the adequacy of the colotomy closure, with the incidence of septic complications directly correlating with the integrity of the closure.…”

Clinical implementation and widespread application of natural orifice translumenal surgery (NOTES) has been limited by the lack of specialized endoscopic equipment, which has prevented the ability to perform complex procedures including colorectal resections. Relative to other types of translumenal access, transanal NOTES using transanal endoscopic microsurgery (TEM) provides a stable platform for endolumenal and direct translu menal access to the peritoneal cavity, and specifically to the colon and rectum. Completely NOTES transanal rectosigmoid resection using TEM, with or without transgastric endoscopic assistance, was demonstrated to be feasible and safe in a swine survival model. The same technique was successfully replicated in human cadavers using commercially available TEM, with end oscopic and laparoscopic instrumentation. This approach also permitted complete rectal mobilization with total mesorectal excision to be performed completely tra nsanally. As in the swine model, transgastric and/or transanal endoscopic assistance extended the length of proximal colon mobilized and overcame some of the difficulties with TEM dissection including limited end oscopic visualization and maladapted instrumentation. This extensive laboratory experience with NOTES tra nsanal rectosigmoid resection served as the basis for the first human NOTES transanal rectal cancer excision using TEM and laparoscopic assistance. Based on this early clinical experience, NOTES transanal approach using TEM holds significant promise as a safe and substantially less morbid alternative to conventional colorectal resection in the management of benign and malignant colorectal diseases. Careful patient selection and substantial impr ovement in NOTES instrumentation are critical to optimize this approach prior to widespread clinical application, and may ultimately permit completely NOTES transanal colorectal resection.
