Colonoscopy is the gold standard for evaluating pathologies of the large bowel, including screening for colorectal cancer. The technological features of current colonoscopes have not progressed much in recent years except for improved image and video display. The technique requires intubation and insufflation of the colon which are operator-dependent and involve a learning curve. Colonoscopy is an invasive procedure whose overall risk of complications is approximately 0.3%, increasing to 2% when polypectomy is performed. The PillCam Colon capsule endoscope (Given Imaging Ltd., Yoqneam, Israel) was developed for use as a safe, minimally invasive, non-sedation requiring, patient-friendly modality to visualize the colon. Only the interpretation of findings requires expertise. PillCam capsule endoscopy could be an alternative approach to colonoscopy for screening large populations. We report the first clinical investigations of the safety, feasibility and performance of colon capsule endoscopy compared with standard colonoscopy.

While hematochezia is common in Crohn's disease (CD), severe gastrointestinal hemorrhage causing hemodynamic instability is rare. Strictures, another frequent complication, usually cause obstructive symptoms. We report the first case of hemorrhagic shock from ulcerated ileal strictures as the initial presentation of CD.

Background: Sarcomatoid carcinoma of the small bowel is an exceedingly rare gastrointestinal tumor characterized by a biphasic cellular pattern of epithelioid and mesenchymal-like cells. Due to its rarity and non-specific clinical presentation, it is frequently misdiagnosed, and there is a lack of standardized management guidelines. We report a case of multiple sarcomatoid carcinoma of the small intestine, presenting initially with gastrointestinal perforation.

The Ohio State University College of Medicine, Columbus, Ohio.
Background: An all-inside endoscopic flexor hallucis longus (FHL) tendon transfer is indicated for the treatment of chronic, full-thickness Achilles tendon defects. The aim of this procedure is to restore function of the gastrocnemius-soleus complex while avoiding the wound complications associated with open procedures.
Description: This procedure can be performed through 2 endoscopic portals, a posteromedial portal (the working portal) and a posterolateral portal (the visualization portal).

Machine learning and its specialized forms, such as Artificial Neural Networks and Convolutional Neural Networks, are increasingly being used for detecting and managing gastrointestinal conditions. Recent advancements involve using Artificial Neural Network models to enhance predictive accuracy for severe lower gastrointestinal (LGI) bleeding outcomes, including the need for surgery. To this end, artificial intelligence (AI)-guided predictive models have shown promise in improving management outcomes.
