No news is bad news – an unusual cause of bleeding in a cirrhotic patient
Authors: A. Badea, M. Birligea, A. Bengus
Journal: Endoscopy (2024)

Abstract Text A case of a 75 years-old female patient, known with multiple cardiovascular risk factors and liver cirrhosis secondary to primary biliary cholangitis, was referred to our clinic for endoscopic investigation of severe anemia. The patient denied any evidence of bleeding. CT scan showed nonspecific localised gastric and ileal wall thickening. Following anemia correction, we performed both gastroscopy and colonoscopy, with normal findings. Next we decided to evaluate small bowel using capsule endoscopy. Two hours from the pyloric region and forty minutes before the cecum, an ulcerated circumferential lesion with stigmata of bleeding was discovered. Surgical management was applied (segmental enterectomy) and the histopathology report was conclusive for low-grade B cell lymphoma.
Cholangitis after plastic stenting of the bile duct: frequent, serious and unpredictable?
Authors: A. Sugeac, T. Voiosu, A. Bengus, B. Mateescu, C. Diaconu, B. Doamna, G. E. Bajdechi, A. M. Voiosu
Journal: Endoscopy (2024)

Aims Endoscopic placement of one or multiple stents during ERCP is the main treatment modality of biliary obstruction of both benign and malignant origin. While technological advancements have allowed a gradual transition from plastic to metal stents in many indications because of improved outcomes and prolonged patency, the use of plastic stents (PS) remains widespread. Although current guidelines recommend scheduled stent exchange at 3 months interval in most indications, the optimum timing of stent exchange across various clinical indications is debatable. Our aim was to compare patency rates between PS placed for benign versus malignant indications and identify risk factors for early stent occlusion.

Combined transvaginal and colonic rendez-vous approach for over-the-scope clip system placement in colo-vaginal fistulae
Authors: G. Giudici, F. Frigo, G. Testa, D. Arese, A. Garripoli, M. A. La Terra, N. Sapone, M. Spandre, F. Coppola
Journal: Endoscopy (2024)

Abstract Text Surgical treatment of colo-vaginal fistulae is often contraindicated due to significant morbidity and mortality. We report two cases of elderly women, referred to our centre after the onset of faecaluria and pneumaturia. Both patients had diverticular disease which prevented endoscopic identification of the colonic orifice of the fistula, so an ultrathin gastroscope was inserted into the vagina to identify the vaginal orifice. Using a rendez-vous technique, a hydrophilic guidewire was inserted from the vaginal side of the fistula, retrieved from the colonic side and used to guide a therapeutic gastroscope equipped with an over-the-scope clip, allowing precise deployment of the over-the-scope clip and consequent complete closure of the fistula. Our experience confirms that over-the-scope clip-assisted closure of colo-vaginal fistulae is an effective and feasible treatment option.

Authors: Xiaojie Wang, Weizhong Jiang, Yu Deng, Zhifen Chen, Zhifang Zheng, Yanwu Sun, Zhongdong Xie, Xingrong Lu, Shenghui Huang, Yu Lin, Ying Huang, Pan Chi
Journal: International Journal of Surgery (2024)

Background: Accurate prediction of successful sphincter-preserving resection (SSPR) for low rectal cancer enables peer institutions to scrutinize their own performance and potentially avoid unnecessary permanent colostomy. The aim of this study is to evaluate the variation in SSPR and present the first artificial intelligence (AI) models to predict SSPR in low rectal cancer patients. Study design: This was a retrospective post hoc analysis of a multicenter, noninferiority randomized clinical trial (LASRE, NCT XXXXXX) conducted in 22 tertiary hospitals across China. A total of 604 patients who underwent neoadjuvant chemoradiotherapy (CRT) followed by radical resection of low rectal cancer were included as the study cohort, which was then split into a training set (67%) and a testing set (33%). The primary end point of this post hoc analysis was SSPR, which was defined as meeting all the following criteria: (1) sphincter-preserving resection; (2) complete or nearly complete TME, (3) a clear CRM (distance between margin and tumor of 1 mm or more), and (4) a clear DRM (distance between margin and tumor of 1 mm or more). Seven AI algorithms, namely, support vector machine (SVM), logistic regression (LR), extreme gradient boosting (XGB), light gradient boosting (LGB), decision tree classifier (DTC), random forest (RF) classifier, and multilayer perceptron (MLP), were employed to construct predictive models for SSPR. Evaluation of accuracy in the independent testing set included measures of discrimination, calibration, and clinical applicability. Results: The SSPR rate for the entire cohort was 71.9% (434/604 patients). Significant variation in the rate of SSPR, ranging from 37.7% to 94.4%, was observed among the hospitals. The optimal set of selected features included tumor distance from the anal verge before and after CRT, the occurrence of clinical T downstaging, post-CRT weight and clinical N stage measured by magnetic resonance imaging. The 7 different AI algorithms were developed and applied to the independent testing set. The LR, LGB, MLP and XGB models showed excellent discrimination with AUROC values of 0.825, 0.819, 0.819 and 0.805, respectively. The DTC, RF and SVM models had acceptable discrimination with AUROC values of 0.797, 0.766 and 0.744, respectively. LR and LGB showed the best discrimination, and all 7 AI models had superior overall net benefits within the range of 0.3-0.8 threshold probabilities. Finally, we developed an online calculator based on the LGB model to facilitate clinical use. Conclusions: The rate of SSPR exhibits substantial variation, and the application of AI models has demonstrated the ability to predict SSPR for low rectal cancers with commendable accuracy.

Tolerability and safety of cholangioscopy and lithotripsy under conscious sedation for refractory choledocholithiasis: experience in a cohort of elder or co-morbid patients
Authors: L. Mebarek, B. Warner, T. Wong, P. Berry, S. Kotha
Journal: Endoscopy (2024)

Aims Cholangioscopy with electrohydraulic lithotripsy (C+EHL) is an effective treatment for choledocholithiasis refractory to conventional endoscopic retrograde cholangiopancreatography (ERCP). Complexity and long duration of the procedure has traditionally required the use of general anaesthesia (GA), but older patients with co-morbidities may not be candidates for this. We assessed the tolerance, safety and efficacy of C+EHL under conscious sedation for refractory choledocholithiasis in a cohort of patients with these characteristics.

Journal: Endoscopy (2024)

Abstract Text A 50-year-old man with a history of Crohn's disease with ileocecal resection and ileocolonic anastomosis presented with abdominal pain and abdominal distension after eating, leukocytosis and elevated PCR. A CT scan showed intestinal obstruction secondary to the presence of two shells at the ileocecal anastomosis. An endoscopic approach was decided. The anastomosis showed signs of postsurgical recurrence with ulcers and stenosis. A seashell was visualized through it. After multiple attempts, the stenosis was crossed, and the foreign body was dislodged with a 5-arm grasping forceps and finally removed with a polyp basket. Although surgery is indicated when a sharp object does not pass through the ileocecal valve in 4-6 days, endoscopic management can first be attempted, being a safe and effective method, reducing the risk of perforation and the need for surgery.

Adult ileocolic intussusception caused by Vanek Tumor – an uncommon entity, a rare underlying cause
Authors: C. Rodrigues, P. Sousa, Â. Domingues, C. Soares, R. Gomes, A. Silva
Journal: Endoscopy (2024)

Abstract Text A 23-year-old woman presented with a 1-day history of cramping abdominal pain in the right inferior quadrant. She was stable on admission with no signs of peritoneal irritation. An abdominopelvic CT showed a 12-cm ileocolic intussusception. Colonoscopy revealed an extensive ileal invagination up to hepatic flexure, with a 40 mm pedunculated polyp as the leading point. Endoscopic reduction was not possible and an ileocolic resection was performed. Histopathology revealed a Vanek tumor, an uncommon benign submucosal connective tissue tumor. Intestinal intussusception, a rare cause of bowel obstruction in adults, is typically due to a pathologic lead point. Although efficient for the management of intussusceptions in children, colonoscopy has limited therapeutic role in adults, with intussusceptions being managed mostly with surgery. [1] [2] [3] [4]
