Endoscopic management of surgical complications.

While the endoscopic management of surgical complications like leaks, fistulas, and perforations is rapidly evolving, its core principles revolve around closure, drainage, and containment. Effectively managing these conditions relies on several factors, such as the underlying cause, chronicity of the lesion, tissue viability, co-morbidities, availability of devices, and expertise required to perform the endoscopy. In contrast to acute perforation, fistulas and leaks often demand a multimodal approach requiring more than one session to achieve the required results.

A novel blood-sensing capsule for rapid detection of upper GI bleeding: a prospective clinical trial.

Background And Aims: Upper GI bleeding (UGIB) is a common medical emergency associated with high resource utilization, morbidity, and mortality. Timely EGD can be challenging from personnel, resource, and access perspectives. PillSense (EnteraSense Ltd, Galway, Ireland) is a novel swallowed bleeding sensor for the detection of UGIB, anticipated to aid in patient triage and guide clinical decision-making for individuals with suspected UGIB.

Neoplasia Diagnosis After Multi-target Stool DNA Is Enhanced Among Lowest Baseline Detectors.

Background And Aims: Variation in colorectal neoplasia detection limits the effectiveness of screening colonoscopy. By evaluating neoplasia detection rates of individual colonoscopists, we aimed to quantify the effects of pre-procedural knowledge of a positive (+) multi-target stool DNA (mt-sDNA) on colonoscopy quality metrics.

Methods: We retrospectively identified physicians who performed a high volume of + mt-sDNA colonoscopies; colorectal neoplasia at post-mt-sDNA colonoscopy was recorded.

Endoscopic ultrasound-guided gastroenterostomy for the management of gastric outlet obstruction: A large comparative study with long-term follow-up.

Gastric outlet obstruction (GOO) is traditionally managed with surgical gastroenterostomy (surgical-GE) and enteral stenting (ES). Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is now a third option. Large studies assessing their relative risks and benefits with adequate follow-up are lacking.

Lumen-apposing metal stents for the treatment of benign gastrointestinal tract strictures: a single-center experience and proposed treatment algorithm.

Background: Lumen-apposing metal stents (LAMS) are an alternative therapeutic option for benign gastrointestinal (GI) tract strictures. Our study aimed to evaluate the safety and efficacy of LAMS for the management of benign GI strictures.

Methods: Consecutive patients who underwent a LAMS placement for benign luminal GI strictures at a tertiary care center between January 2014 and July 2021 were reviewed.

Phase II trial of weekly erlotinib dosing to reduce duodenal polyp burden associated with familial adenomatous polyposis.

Importance: Patients with familial adenomatous polyposis (FAP) are at markedly increased risk for duodenal adenomas and cancer. Combination sulindac and erlotinib was previously shown to reduce duodenal polyp burden but was associated with a relatively high adverse event (AE) rate.

Objective: To evaluate if a once weekly dosing schedule for erlotinib intervention improves the AE profile, while still providing efficacy with respect to reduced polyp burden, in participants with FAP.

Retained Food During Esophagogastroduodenoscopy Is a Risk Factor for Gastric-to-Pulmonary Aspiration.

Background: Residual food (RF) during esophagogastroduodenoscopy (EGD) is thought, but not proven, to be a risk factor for gastric-to-pulmonary aspiration.

Aims: The aims of this study were to determine the prevalence of RF during EGD, to investigate whether RF was associated with an increased risk of aspiration, especially when monitored anesthesia care (MAC) or general anesthesia (GA) were administered, and to determine whether aspiration associated with RF led to a more severe clinical outcome.

Methods: Patients undergoing EGD between October 2012 and September 2018 were identified.

Erratum: Gastrointestinal defect closure using a novel through-the-scope helix tack and suture device compared to endoscopic clips in a survival porcine model (with video).

Inhibition of the BMP pathway prevents development of Barrett's-associated adenocarcinoma in a surgical rat model.

Introduction: Esophageal adenocarcinoma (EAC) is an aggressive cancer, associated with reflux esophagitis and intestinal metaplasia (IM). One underlying biological mechanism, which possibly drives the development of EAC, is the dysregulated expression of Bone Morphogenetic Proteins (BMPs).

Aim: To investigate if local delivery of Noggin, a BMP antagonist, reduced EAC.

Efficacy and safety of combined endoscopic cyanoacrylate injection and balloon-occluded retrograde transvenous occlusion (BRTOcc) of gastrorenal shunts in patients with bleeding gastric fundal varices.

Background: Endoscopic cyanoacrylate (glue) injection of fundal varices may result in life-threatening embolic adverse events through spontaneous gastrorenal shunts (GRSs). Balloon-occluded retrograde transvenous occlusion (BRTOcc) of GRSs during cyanoacrylate injection may prevent serious systemic glue embolization through the shunt. This study aimed to evaluate the efficacy and safety of a combined endoscopic-interventional radiologic (BRTOcc) approach for the treatment of bleeding fundal varices.

Gastrointestinal defect closure using a novel through-the-scope helix tack and suture device compared to endoscopic clips in a survival porcine model (with video).

Endoscopic resections are associated with bleeding and perforation and may be managed with through-the-scope (TTS) clips, over-the-scope clips and endoscopic suturing. The aim of this preclinical study was to compare technical success of closure using a novel TTS tissue helix tack and suture device (X-Tack) to TTS clips in a porcine model. Four subjects underwent 40 mucosal resections, diameter range 25-50 mm, in the stomach (n = 24) and colon (n = 16).

Randomized Phase II Trial of Polyphenon E versus Placebo in Patients at High Risk of Recurrent Colonic Neoplasia.

Polyphenon E (Poly E) is a green tea polyphenol preparation whose most active component is epigallocatechin gallate (EGCG). We studied the cancer preventive efficacy and safety of Poly E in subjects with rectal aberrant crypt foci (ACF), which represent putative precursors of colorectal cancers. Eligible subjects had prior colorectal advanced adenomas or cancers, and had ≥5 rectal ACF at a preregistration chromoendoscopy.

Palliative treatment for malignant gastrointestinal obstruction with peritoneal carcinomatosis: enteral stenting versus surgery.

Management of malignant gastrointestinal obstruction (MGIO) is more challenging in the presence of peritoneal carcinomatosis (PC). Outcomes data to guide the management of MGIO with PC are lacking. We aimed to compare the clinical outcomes and adverse events between endoscopic and surgical palliation and identify predictors of stent success in patients with MGIO with PC.

Use of Home Enteral Nutrition in Malnourished Post-Bariatric Surgery Patients.

Background: Bariatric surgery is by far the most effective treatment option available for successfully achieving and maintaining weight loss in the obese population, but it can also be associated with complications that lead to malnutrition. There is limited data on how enteral nutrition (EN) can be used to provide nutrition support in such cases.

Methods: Retrospective review of our Home Enteral Nutrition (HEN) database was conducted from February 2013 to April 2018 to identify patients who received HEN because of bariatric surgery-related complication.

Extrabiliary applications of fully covered antimigration biliary metal stents.

Background And Aims: Endoscopic stent placement in luminal GI strictures is not always feasible with traditional stents. For example, standard luminal stent delivery catheters may not successfully traverse severe strictures, and enteral stents may not be suitable for sites in the GI tract that pose significant adverse events if downstream migration were to occur. We demonstrate extrabiliary applications of specialized, fully covered antimigration biliary metal stents.

Performance and Predictors of Migration of Partially and Fully Covered Esophageal Self-Expanding Metal Stents for Malignant Dysphagia.

Background & Aims: Self-expanding metal stents (SEMS) are routinely used to palliate malignant dysphagia. However esophageal SEMS can migrate or obstruct due to epithelial hyperplasia. The aim of this study was to evaluate the rates and factors predicting migration and obstruction, and the nutritional outcomes in partially covered (pc) vs.
