AIM: Over-the-scope-clip (OTSC) System is a relatively new endoluminal intervention for gastrointestinal (GI) leaks, fistulas, and bleeding. Here, we present a single center experience with the device over the course of 4 years. METHODS: Retrospective chart review was conducted for patients who received endoscopic OTSC treatment. Primary outcome is the resolution of the original indication for clip placement. Secondary outcomes are complications and time to resolution...

Direct oesophagoscopy is largely a diagnostic procedure performed for a variety of symptoms (e.g. unilateral otalgia or odonophagia) or as part of a panendoscopy to exclude a synchronous primary; therefore good visualisation of abnormal mucosa is essential. The current standard oesophagoscopy technique involves direct visualisation from approximately 25cm down a narrow, illuminated oesophagoscope limiting visualisation of abnormal mucosa. Usually performed by a single operator, the technique is difficult to teach, as the trainee is unable to visualise what the trainer is seeing endoluminally and visa versa...

The only accepted treatment for coeliac disease is strict adherence to a gluten-free diet. This type of diet may give rise to reduced patient quality of life with economic and social repercussions. For this reason, dietary transgressions are common and may elicit intestinal damage. Several treatments aimed at different pathogenic targets of coeliac disease have been developed in recent years: modification of gluten to produce non-immunogenic gluten, endoluminal therapies to degrade gluten in the intestinal lumen, increased gluten tolerance, modulation of intestinal permeability and regulation of the adaptive immune response...

Young Kwan Cho, Seong Hwan Kim
Peroral endoscopic myotomy (POEM) has been established as an optional treatment for achalasia. POEM is an endoluminal procedure that involves dissection of esophageal muscle fibers followed by submucosal tunneling. Inoue first attempted to use POEM for the treatment of achalasia in humans. Expanded indications of POEM include classic indications such as type I, type II, type III achalasia, failed prior treatments, including Botulinum toxin injection, endoscopic balloon dilation, laparoscopic Heller myotomy, and hypertensive motor disorders such as diffuse esophageal spasm, jackhammer esophagus...

Colonoscopy is the gold standard for colon cancer screening. It has led to a decrease in the incidence of colorectal cancer mortality. Colon perforation is a feared complication of this procedure with high morbidity and substantial mortality. Due to the high volume of colonoscopies performed, the absolute number of colonoscopic perforations is relatively high. It leads to a substantial cost to the patient and the health system. Understanding the mechanisms and the risk factors may help in preventing perforation...

PURPOSE: Selective cerebral perfusion with the open proximal technique for thoracoabdominal aortic repair has not been conclusively validated because of its procedural complexity and unreliability. We report the clinical outcomes, particularly the cerebroneurological complications, of an open proximal procedure using selective cerebral perfusion. METHODS: A retrospective chart review identified 30 patients between 2007 and 2015 who underwent aortic repair through left lateral thoracotomy with selective cerebral perfusion, established through endoluminal brachiocephalic and left carotid artery and retrograde left axillary artery...

BACKGROUND: Leaks from the upper gastrointestinal tract often pose a management challenge, particularly when surgical treatment has failed or is impossible. Vacuum therapy has revolutionised the treatment of wounds, and its role in enabling and accelerating healing is now explored in oesophagogastric surgery. METHODS: A piece of open cell foam is sutured around the distal end of a nasogastric tube using a silk suture. Under general anaesthetic, the foam covered tip is placed endoscopically through the perforation and into any extra-luminal cavity...

The use of endoluminal stents to treat anastomotic leaks post oesophagogastric resection remains controversial. While some advocate stents to expedite recovery, others advise caution due to the risk of major morbidity and mortality. We describe a case of anastomotic leak following total gastrectomy for adenocarcinoma treated with a self-expanding metallic stent. Complications with the initial stent were treated with a further stent, which compromised the function of the oesophagus and eroded into the aorta, necessitating a colonic reconstruction and endovascular aortic stenting...

BACKGROUND: Perforations and anastomotic leaks of the gastrointestinal tract are severe complications, which carry high morbidity and mortality and management of these is a multi-disciplinary challenge. The use of endoluminal vacuum (EVAC) therapy has recently proven to be a useful technique to manage these complications. We report our institution's experience with this novel technique in the chest, abdomen, and pelvis. METHODS: This is a retrospective review of an IRB approved registry of all EVAC therapy patients from July 2013 to December 2016...

Traditional surgeries involve accessing body cavities, such as the abdomen and thorax, via incisions that divide skin and muscle. These operations result in postoperative pain and convalescence, and a risk of complications such as wound infection and hernia. The development of flexible endoscopy allowed diseases as varied as gastrointestinal bleeding and colon adenomas to be treated without incisions, but this technique is restricted by its endoluminal nature. A novel category of surgical endoscopic procedures has recently been developed that uses flexible endoscopic techniques to enter and access the submucosa of the gastrointestinal tract...

OBJECTIVES: Arteriovenous malformations (AVMs) are complex vascular lesions. Surgical excision is the treatment of choice, but is often not achievable. Embolo-sclerotherapy alone is associated with high recurrence rates. This study tested the hypothesis that seeding hydrogel conditioned bone marrow derived mesenchymatous stem cells (BM-MSCs) in an AVM nidus model induces solid microvascular occlusion through endoluminal tissue growth. METHODS: AVMs were modelled as arteriovenous microvascular nidus, using swine rete mirabile, a plexiform intracranial structure composed of arterial microvessels that extensively anastomose...

BACKGROUND: Spring-mediated distraction enterogenesis has been shown to increase the length of an intestinal segment. The goal of this study is to use suture plication to confine a spring within an intestinal segment while maintaining luminal patency to the rest of the intestine. METHODS: Juvenile mini-Yucatan pigs underwent placement of nitinol springs within a defunctionalized Roux limb of jejunum. A 20 French catheter was passed temporarily, and sutures were used to plicate the intestinal wall around the catheter at both ends of the encapsulated spring...

Congenital diaphragmatic hernia (CDH) is a birth defect characterized by failed closure of the diaphragm, allowing abdominal viscera to herniate into the thoracic cavity and subsequently impair pulmonary and vascular development. Despite improving standardized postnatal management, there remains a population of severe CDH for whom postnatal care falls short. In these severe cases, antenatal surgical intervention (fetoscopic endoluminal tracheal occlusion [FETO]) may improve survival; however, FETO increases the risk of preterm delivery, is not widely offered, and still fails in half of cases...

Postoperative leak is a serious complication of bariatric surgery and often results in significant morbidity and mortality. Stent placement is a less invasive alternative to surgery for the treatment of bariatric surgical leak. We evaluated the efficacy and complications of covered self-expandable metal stents (SEMS) in the treatment of post-bariatric surgical leak. We retrospectively reviewed patients who underwent stent placement for leak after bariatric surgery. Leak was diagnosed by upper gastrointestinal series or was visualized during the endoscopy...

Spontaneous right hepatic artery branch gallbladder fistula is a rare condition. Our case reported a spontaneous fistula between the right branch of the hepatic artery and the gall bladder. It constitutes a rare cause of haemobilia. In fact, the most common aetiology of haemobilia is traumatic or iatrogenic secondary to hepatobiliary surgery or interventions. Diagnosis of vascular-biliary fistula is not easy. The gallbladder endoluminal clot can mimic a mass, as in our patient. Selective arterial angiography is helpful in identifying the source of gastrointestinal haemorrhage...

OBJECTIVE: Assessment of coronary stenosis severity is crucial in clinical practice. This study proposes a novel method to generate 3D models of stenotic coronary arteries, directly from 2D coronary images, and suitable for immediate assessment of the stenosis severity. METHODS: From multiple 2D X-ray coronary arteriogram projections, 2D vessels were extracted. A 3D centreline was reconstructed as intersection of surfaces from corresponding branches. Next, 3D luminal contours were generated in a two-step process: first, a Non-Uniform Rational B-Spline (NURBS) circular contour was designed and, second, its control points were adjusted to interpolate computed 3D boundary points...
