Local Myoelectric Sensing During Human Colonic Tissue Perfusion.

Anastomotic leakage (AL) is one of the most devastating complications after colorectal surgery. The verification of the adequate perfusion of the anastomosis is essential to ensuring anastomosis integrity following colonic resections. This study aimed to evaluate the efficacy of measuring the electrical activity of the colonic muscularis externa at an anastomosis site for perfusion analysis following colorectal surgery.

Factors Associated With Biologic Therapy After Ileal Pouch-Anal Anastomosis in Patients With Ulcerative Colitis.

Background: Patients with ulcerative colitis (UC) undergoing proctocolectomy and ileal pouch-anal anastomosis (IPAA) may eventually require biologic therapy. Factors associated with biologic therapy after IPAA have not been previously studied.

Methods: All patients with UC after total proctocolectomy and IPAA who were followed at Rabin Medical Center comprehensive pouch clinic and who consented to prospective observational follow-up were included.

Discordant Effects of Janus Kinase Inhibition Ex Vivo on Inflammatory Responses in Colonic Compared to Ileal Mucosa.

Background And Aims: Janus kinase [JAK] inhibitors are used for treating inflammatory bowel diseases [IBD]. We aimed to identify the molecular effects of JAK inhibition in human intestinal mucosa, considering IBD location and phenotype.

Methods: Colonic and ileal explants from patients with ulcerative colitis [UC], Crohn's disease [CD], and non-IBD controls [NC] were assessed for levels of phosphorylated signal transducers and activators of transcription [p-STAT] and expression of inflammatory genes in response to an ex vivo JAK inhibitor [tofacitinib].

Risk Factors for Rectal Cancer Recurrence after Local Excision of T1 Lesions from a Decade-Long Multicenter Retrospective Study.

Local surgical excision of T1 rectal adenocarcinoma is a well-established approach. Yet, there are still open questions regarding the recurrence rates and its risk factors. A retrospective multicenter study including all patients who underwent local excision of early rectal cancer with an open or MIS approach and had a T1 lesion from 2010 to 2020 in six academic centers.

Comparison of Post-Operative Outcomes of Right Colectomy between Crohn's Disease and Adenocarcinoma of the Right Colon: A Retrospective Cohort Study.

(1) Crohn's disease (CD) and right-sided colorectal-carcinoma (CRC) are two common indications for right colectomies. Many studies have tried to identify risk factors associated with post-operative complications for both CD and CRC. However, data directly comparing the outcomes of the two are sparse.
