Background And Aims: The ileoanal pouch (IPAA) provides patients with ulcerative colitis (UC) that have not responded to medical therapy an option to retain bowel continuity and defecate without the need for a long-term stoma. Despite good functional outcomes, some pouches fail, requiring permanent diversion, pouchectomy, or a redo pouch. The incidence of pouch failure ranges between 2 and 15% in the literature. We conducted a systematic review and meta-analysis aiming to define the prevalence of pouch failure in patients with UC who have undergone IPAA using population-based studies.
Methods: We searched Embase, Embase classic and PubMed from 1978 to 31st of May 2021 to identify cross-sectional studies that reported the prevalence of pouch failure in adults (≥ 18 years of age) who underwent IPAA for UC.
Results: Twenty-six studies comprising 23,389 patients were analysed. With < 5 years of follow-up, the prevalence of pouch failure was 5% (95%CI 3-10%). With ≥ 5 but < 10 years of follow-up, the prevalence was 5% (95%CI 4-7%). This increased to 9% (95%CI 7-16%) with ≥ 10 years of follow-up. The overall prevalence of pouch failure was 6% (95%CI 5-8%).
Conclusions: The overall prevalence of pouch failure in patients over the age of 18 who have undergone restorative proctocolectomy in UC is 6%. These data are important for counselling patients considering this operation. Importantly, for those patients with UC being considered for a pouch, their disease course has often resulted in both physical and psychological morbidity and hence providing accurate expectations for these patients is vital.

Ileal pouch-anal anastomosis for ulcerative colitis: 30-year analysis on surgical evolution and patient outcome.
BJS Open

Department of Abdominal Surgery, University Hospitals Leuven, KU Leuven, Leuven, Belgium.
Background: Proctocolectomy with ileal pouch-anal anastomosis is the treatment of choice for patients with ulcerative colitis with medical refractory disease or dysplasia. The aim of this research was to describe the evolution of ileal pouch-anal anastomosis surgery and surgical outcomes over a three-decade interval in a high-volume referral centre.
Methods: All consecutive patients undergoing ileal pouch-anal anastomosis for ulcerative colitis between 1990 and 2022 at the University Hospitals of Leuven were retrospectively included.
Thermoelectrochemical formation of a solid electrolyte interphase on a silicon negative electrode to enhance the durability of silicon-enriched lithium-ion batteries by compositional modification.

The SiO electrode interface is passivated with a SiO layer, which hinders the deposition of an inorganic solid electrolyte interphase (SEI) due to its high surface work function and low exchange current density of electrolyte decomposition. Consequently, a thermally vulnerable, organic-based SEI formed on the SiO electrode, leading to poor cycling performance at elevated temperatures. To address this issue, the SEI formation process is thermoelectrochemically activated.

Purpose: The most frequently used surgical procedures for periprosthetic joint infections (PJIs) are debridement, antibiotics, and implant retention (DAIR), as well as single- or two-stage revision arthroplasty. The choice of surgery is made depending on the full maturation of the biofilm layer. The purpose of this study was to evaluate the biofilm formation and microbial growth using common PJI-causing agents and compare its development on the implant surface.

Background: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is a common surgical procedure for ulcerative colitis and familial adenomatous polyposis. IPAA strictures are a known complication, often requiring surgical intervention. Endoscopic interventions offer a less invasive alternative, but their safety and efficacy remain uncertain.

Background: Surgical fundoplication remains integral in managing gastroesophageal reflux disease (GERD) by addressing gastroesophageal valve incompetence. This study introduces a novel hybrid approach, the Eversion Cruroplasty and Collar Overwrap (ECCO) procedure, aiming to combine benefits of conventional partial wrapping and posteromedial cardiopexy, considering gastric fundus anatomical peculiarities as an anti-reflux barrier.
Methods: A retrospective analysis of pediatric patients presenting with refractory GERD from 2021 to 2023 was conducted.
