Intestinal Perforation Caused by Lumboperitoneal Shunt Insertion Repaired with an Over-the-Scope Clip
We report the case of a small intestinal perforation in a 73-year-old-woman that occurred after the insertion of a lumboperitoneal shunt. A positive cerebrospinal fluid culture and high cerebrospinal fluid white blood cell count indicated a retrograde bacterial infection, and computed tomography revealed that the peritoneal tip of the shunt catheter was located in the lumen of the gastrointestinal tract. We repaired the perforation endoscopically using an over-the-scope clip, and the patient's recovery was uneventful. Use of an over-the-scope clip could be an effective and minimally invasive treatment for intestinal perfor...

Endoscopic Ultrasound Through-the-Needle Biopsy for the Diagnosis of an Abdominal Bronchogenic Cyst.
Authors: Cassiani J, Crinò SF, Manfrin E, Rivelli M, Gabbrielli A, Guglielmi A, Pedrazzani C Abstract A 57-year-old woman with epigastric pain was diagnosed with a 6-cm abdominal cystic lesion of unclear origin on cross-sectional imaging. Endoscopic ultrasound (EUS) demonstrated a unilocular cyst located between the pancreas, gastric wall, and left adrenal gland, with a regular wall filled with dense fluid with multiple hyperechoic floating spots. A 19-G needle was used to puncture the cyst, but no fluid could be aspirated. Therefore, EUS-guided through-the-needle biopsy (EUS-TTNB) was performed. Histologica...

Parapneumonic Effusion and Tension Pneumothorax after Diverticular Peroral Endoscopic Myotomy in a Woman with Large Epiphrenic Diverticulum: A Case Report and Literature Review.
Authors: Shiu SI Abstract Esophageal diverticula (ED) represents a group of rare conditions that warrant intervention when they are symptomatic or coexisting with pulmonary disorders. Few literature reviews have described this patient entity or discussed the postoperative outcome. Therefore, I present the case of a 59-year-old woman with symptoms of dysphagia who was significantly underweight, which was conducive to the diagnosis of symptomatic ED. Because she was a poor candidate for surgery, she received a diverticular peroral endoscopic myotomy. She subsequently developed parapneumonic effusion and tension pneum...

A Rare Case of Coil Migration into the Duodenum after Embolization of a Right Colic Artery Pseudoaneurysm.
We report a rare case of coil migration to the duodenal lumen after embolization of a right colic artery pseudoaneurysm. To the best of our knowledge, this is the first case of coil migration after a right colic artery embolization. The patient exhibited no symptoms and was treated conservatively without any intervention. Some previous reports have demonstrated spontaneous coil passage and successful conservative management. Our case supports conservative treatment as the primary treatment for asymptomatic patients. Clinicians should assess the risks and benefits of coil removal in asymptomatic patients before performing a...

Early Lumen-Apposing Metal Stent Dysfunction Complicating Endoscopic Ultrasound-Guided Gastroenterostomy: A Report of Two Cases.
We report two cases with early lumen-apposing metal stent dysfunction, compromising patency. One case showed food impaction after three weeks, and hyperplastic tissue overgrowth with a buried distal flange six weeks after stent placement. The latter was successfully treated by argon plasma coagulation, stent removal, and deployment of a larger-diameter lumen-apposing metal stent. The second case showed a narrowed luminal diameter of the stent and jejunal pressure ulcerations after three weeks. The narrowing was successfully treated by balloon dilation. Eight weeks later, hyperplastic tissue overgrowth at the distal flange ...

Stepwise Algorithmic Approach to Endoscopic Removal of Biliary Partially Covered and Uncovered Self-Expanding Metal Stents (with Videos).
We present our technique and experience of endoscopic extraction of biliary stents in two patients with a UCMS and three patients with a PCMS. Three of the five patients had a previous failed attempt of stent extraction at an outside hospital. Overall, our composite success rate was 80% (4/5). The individual success rate was 100% (3/3) for PCMSs and 50% (1/2) for UCMSs. The stent-in-stent technique, in which a fully covered metal stent is placed through an existing UCMS/PCMS, was used in 60% (3/5) of the cases, with a success rate of 66.7% (2/3).

Role of Peroral Endoscopic Myotomy (POEM) in the Management of Esophageal Diverticula.
Authors: Miutescu BP, Khan S, Mony S, Khashab MA Abstract Esophageal diverticula are uncommon; however, when present, they can cause symptoms of dysphagia, regurgitation, and chest pain. Based on location and pathophysiological characteristics, they are classified as pulsion- and traction-type diverticula. In the past, the open surgical approach was the only treatment available; however, in the past few decades, transoral incisionless approaches in the form of rigid and flexible endoscopy have gained popularity. Diverticular peroral endoscopic myotomy has emerged as an alternative treatment option. In this paper, w...
