The etiologies for nonneoplastic rectal strictures in dogs included foreign bodies, postoperative formation, inflammatory disease, and congenital malformation. Sixteen of 19 dogs underwent balloon dilatation therapy, and 14 of these 16 dogs received intralesional triamcinolone injections. Following dilatation, clinical signs persisted in one dog, improved with continued medical therapy in five dogs, and resolved in nine dogs for the duration of their follow-up period (mean 18 months; median 12 months); one dog was lost to follow-up. Balloon dilatation and triamcinolone were parts of a treatment regimen that improved clinical signs in the majority of dogs diagnosed with nonneoplastic rectal strictures.

Article Synopsis
- The study examines urological complications in patients who underwent total pelvic exenteration (TPE) for locally advanced and recurrent rectal cancer, highlighting a significant occurrence of issues post-surgery.
- A total of 128 patients were assessed, with common complications being transient acute kidney injury and urinary tract infections, resulting in an overall complication rate of 51.6%.
- The findings indicate that the type of cancer (LARC vs RRC) and prior radiation treatment did not significantly influence the rates of urological complications.

Diversion colitis is a common phenomenon affecting patients after defunctioning ileostomy. We present a complex case of diversion colitis where the patient was deemed unsuitable for restorative surgery due to multiple areas of stricturing in a long defunctioned colonic segment. Despite initial treatments with rectally administered topical mesalazine, butyrate enemas and topical steroid therapy, the patient remained symptomatic with rectal bleeding and mucus discharge.

Objective: Upadacitinib, an oral Janus kinase inhibitor (JAKi), is approved for inflammatory bowel disease (IBD) in adults. As on-label use will face significant delay in pediatrics, a real-world understanding of safety and efficacy in children is critical.
Methods: This is a single-center retrospective cohort of pediatric subjects (ages 9-20 years) with a diagnosis of IBD initiated on upadacitinib.

Aim: Despite advancements in therapeutic options for Crohn's disease (CD), strictureplasty is a mainstay bowel-preserving technique for small bowel CD. We sought to audit international practice across three high-volume centres since the widespread use of biologic medication.
Methods: A retrospective audit was performed for all strictureplasties undertaken for small bowel CD, over a 15-year period (2006-2021), in three high-volume centres in the United Kingdom and Italy.

Introduction: The perineal body preserving posterior sagittal anorectoplasty (PSARP) (PPP) is a novel modification of the original PSARP for female patients with rectovestibular fistulas designed to eliminate the risk of perineal body dehiscence. This study aims to examine the outcomes following PPP.
Methods: A retrospective, single-institution study was performed examining female patients with rectovestibular fistula who underwent PPP between January /2020 and December 2023.
