A 68-year-old man with episodes of overt obscure gastrointestinal (GI) bleeding was investigated with multiple upper and lower GI endoscopies, CT enterography and capsule endoscopy, but no cause was found. He then presented acutely with small bowel obstruction. A laparotomy revealed complete small bowel obstruction secondary to jejunal intussusception over a 4 cm intraluminal polyp. Following resection and primary anastomosis, histology revealed that the polyp was a GI stromal tumour (GIST). This is an exceptionally uncommon presentation of a rare tumour. It is surprising that this tumour was not detected by CT enterography and not seen on capsule endoscopy. Immunohistochemistry and mutation analysis of the GIST suggested that it had a low risk of metastatic disease, but a high risk of recurrence. Staging CT scans did not reveal evidence of distal spread. The patient is currently receiving 3 years of chemotherapy with imatinib.

Background: Patients with prior abdominal surgeries are at higher risk of intra-peritoneal adhesions near the trocar entry site, increasing the likelihood of organ injury during laparoscopic cholecystectomy (LC). This study evaluates a novel technique where the epigastric trocar is inserted first, after creating pneumoperitoneum, to allow safe dissection of adhesions under direct vision before placing the umbilical trocar.
Methods: This prospective study included 244 patients with symptomatic uncomplicated gallstone disease and a history of previous abdominal surgeries extending to the umbilicus.

Background: Despite the availability of several biologics for ulcerative colitis (UC), there remains a critical need to identify first-line treatment biologics. The superiority of infliximab (IFX) over vedolizumab (VED) and ustekinumab (UST) was evaluated as initial UC treatments in patients with biologic-naïve UC.
Methods: This multicenter, randomized control trial was conducted across 20 Japanese medical institutions.

Background: Adhesive small bowel obstruction (ASBO) is a rare, nonobstetrical abdominal emergency. Optimal management of ASBO during pregnancy remains unknown. This study analyzes management trends and outcomes of pregnant patients with ASBO in the United States.

To develop an augmentation method that simulates cone-beam computed tomography (CBCT) related motion artifacts, which can be used to generate training-data to increase the performance of artificial intelligence models dedicated to auto-contouring tasks.The augmentation technique generates data that simulates artifacts typically present in CBCT imaging.

Intoxication of sheep and cattle by recently occurred in Uruguay and Argentina in association with severe drought. Although the disease was experimentally reproduced in sheep in the 1970s, there is limited information on clinical and pathologic findings of sheep experimentally intoxicated by this beetle. Here, we described the clinical, gross, and microscopic findings in 3 sheep orally dosed with (treatment group, TG) and in 2 control sheep (control group, CG) dosed with distilled water.
