After the first report by Kalloo et al on transgastric peritoneoscopy in pigs, it rapidly became apparent that there was no room for an under-evaluated concept and blind adoption of an appealing (r)evolution in minimal access surgery. Systematic experimental work became mandatory before any translation to the clinical setting. Choice and management of the(More)
BACKGROUND Endoscopic treatment of gastric leaks (GL) following sleeve gastrectomy (SG) involves different techniques; however, standard management is not yet established. We report our experience about endoscopic internal drainage of leaks using pigtail stents coupled with enteral nutrition (EDEN) for 4 to 6 weeks until healing is achieved. METHODS In 21(More)
We present a case of a man with amyotrophic lateral sclerosis who developed superior mesenteric artery syndrome (SMAS) following the confection of feeding jejunostomy. He was successfully managed by conservative treatment. Left lateral positioning during enteral feeding allowed quick resolution of the occlusive state. Various surgical interventions have(More)
Mirizzi syndrome is a rare cause of benign biliary obstruction and is often predisposed by low insertion of the cystic duct on the common hepatic duct. Through a case series of three patients, we emphasize the importance of double cannulation (cystic duct and hepatic duct) followed by sphincterotomy and large balloon papillary dilatation for successful(More)
BACKGROUND The most effective treatment of achalasia is Heller myotomy. OBJECTIVE To explore a submucosal endoscopic myotomy technique tailored on esophageal physiology testing and to compare it with the open technique. DESIGN Prospective acute and survival comparative study in pigs (n = 12; 35 kg). SETTING University animal research center. (More)
BACKGROUND Leaks are considered one of the major complications of laparoscopic sleeve gastrectomy (LSG) with a reported rate up to 7 %. Drainage of the collection coupled with SEMS deployment is the most frequent treatment. Its success is variable and burdened by high morbidity and not irrelevant mortality. The aim of this paper is to suggest and establish(More)
BACKGROUND AND STUDY AIM Endoscopic therapy of brisk upper gastrointestinal bleeding remains challenging. A proprietary nanopowder (TC-325) has been proven to be effective in high pressure bleeding from external wounds. The efficacy and safety of TC-325 were assessed in a survival gastrointestinal bleeding animal model. METHOD 10 animals were randomized(More)
Erectile dysfunction (ED) is frequent in patients with essential hypertension (EH); a likely common pathogenetic pathway could be a reduced ability of arteriolar vascular smooth muscle (VSM) to relax. Increasing intracellular levels of cGMP reduce the contractile status of VSM; on the contrary, type 5 cGMP-specific phosphodiesterase (PDE5, codified by PDE5A(More)
BACKGROUND AND STUDY AIMS Minimizing the invasiveness of operations by using natural orifice transluminal endoscopic surgery (NOTES) may reduce adhesion formation. The aim of the study was to compare rates of adhesion formation after peritoneoscopy with liver biopsy by laparotomy, laparoscopy, and transgastric NOTES. MATERIALS AND METHODS Experimental(More)
In this retrospective, comparative study a total of 107 patients, presenting with malignant inoperable strictures of common bile duct, due to a pancreatico-biliary malignancy, underwent palliative treatments. In a group, consisting of 82 patients (76.64%), endoscopic stenting procedures were performed; polyethylene stents or self-expanding metal stents were(More)
