This article, published in the journal Endoscopy, describes a case study of a 92-year-old patient who was admitted with choledocholithiasis (gallstones in the bile duct). During an ERCP (endoscopic retrograde cholangiopancreatography) procedure, a perforation was observed in the pyriform sinus of the esophagus. To address this, a self-expandable metal stent was inserted to close the wall defect. After 48 hours, the procedure was repeated, and the stent was removed. The article includes a video demonstrating the procedure. The authors of the article are listed as L. Guilabert, B. Martínez-Moreno, P. López-Guillén, L. Bernal-Luján, A. Hurtado-Soriano, O. Belén Galipienso, F. J. Puchol Rodrigo, N. Sala-Miquel, and J. R. Aparicio. [Extracted from the article]

This article compares the quality of colonoscopies performed with a two-handed technique (where the colonoscope is manipulated only by the endoscopist) versus a four-handed technique (with nursing assistance). The study analyzed 109 colonoscopies performed by four endoscopists in a hospital, focusing on three quality criteria: cecal intubation rate (CIR), adenoma detection rate (ADR), and complication rate (CR). The results showed that the CIR was 100% in both groups, while the ADR was 40.5% in the two-handed group and 26.4% in the four-handed group, with no statistically significant difference. The CR was 4.7% in the two-handed group and 7.7% in the four-handed group, also with no statistically significant difference. The study concludes that, based on these results, neither technique can be considered superior in terms of quality or safety. [Extracted from the article]

This article provides a descriptive analysis of direct endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ) procedures performed at a tertiary hospital from 2016 to 2023. The study compares cases performed by direct puncture of the loop to those assisted by a nasobiliary catheter to identify potential factors that influence the use of the direct technique. The results show that direct EUS-GJ had a technical success rate of 85.7% with no complications, and it was most commonly used for distal stenosis, tumor necrosis, and duodenal tumors. However, the study acknowledges that more research is needed to validate these findings due to the small sample size and single-center nature of the study. [Extracted from the article]

This article compares the rates of complications, hospital stay, and mortality between surgical and endoscopic treatment of benign colonic polyps. The study included 196 patients with benign lesions, with 98 in each treatment group. The endoscopic treatment group had fewer complications, a lower need for reoperation, and a shorter hospital stay compared to the surgical group. The prevalence of recurrence in endoscopically removed colonic lesions was low and most were detected during the first colonoscopy. [Extracted from the article]

This article, published in the journal Endoscopy, presents a case report of a 72-year-old male patient with lung cancer metastases in the jejunum. The patient initially presented with symptoms such as paresthesias, loss of strength in the right upper limb, and partial loss of vision. Further examinations, including a cranial CT scan and gastroscopy, revealed metastatic lesions in the small intestine. Biopsies confirmed that these lesions were metastases of the known pulmonary carcinoma. The study highlights the possibility of lung cancer metastasizing to the small intestine, causing umbilicated lesions with ulcers and potential bleeding. [Extracted from the article]

A 58-year-old male underwent a surgical procedure called a cephalic duodenopancreatectomy (Whipple procedure) to treat pancreatic adenocarcinoma. One year after the surgery, he experienced abdominal pain and a computed tomography scan revealed partial necrosis of the afferent jejunal loop. A gastroscopy was performed and a foreign body, identified as a fragment of the jejunum wall, was found. Biopsies confirmed the presence of necrohemorrhagic debris, indicating ischemic necrosis of the afferent loop. The foreign body was subsequently removed. [Extracted from the article]

This article discusses the complexity of endoscopic management in patients with chronic pancreatitis (CP). The case study involves a 71-year-old patient with CP who presented with painless jaundice and benign common bile duct stenosis. Due to duodenal edema, ERCP was unsuccessful, and EUS drainage was requested. After an unsuccessful rendezvous, cholecystoduodenostomy was performed, and a rendezvous was performed through the gallbladder using a metallic stent. However, the stent migrated proximally and could not be removed by ERCP. The article describes the successful removal of the stent through EUS-guided puncture and the placement of a new stent.

This article, published in the journal Endoscopy, presents a systematic review and meta-analysis of the risk factors for metachronous colorectal cancer (CRC) or advanced lesions after endoscopic resection of serrated polyps (SPs). The study found that SPs are precursors to 30% of CRCs, but there are discrepancies in surveillance recommendations. The researchers assessed the risk characteristics associated with a higher risk of metachronous CRC or total metachronous advanced lesions (TMAL). They found that the risk of metachronous CRC is significantly higher in patients with advanced SPs, supporting the current recommendation for 3-year surveillance in these patients.
