ABSTRACT
Induction of remission in biologic-experienced individuals with moderate to severe Crohn's disease (CD) can be a challenge. We hereby present a case of CD with secondary non-response to infliximab. Adding methotrexate and switching to ustekinumab plus methotrexate did not stop the inflammatory process. Therefore, combination therapy with two classes of biologics consisting of ustekinumab and adalimumab plus methotrexate was initiated. He achieved clinical remission in 4 weeks and remained on triple therapy for 6 months which was subsequently tailored to adalimumab/methotrexate combination therapy due to insurance restriction on ustekinumab. He remained in remission for the duration of follow-up, 14 months after initiation of triple therapy and 8 months after switching to methotrexate/adalimumab biologic monotherapy. Triple therapy with anti-TNF, IL-12/23 inhibitor and methotrexate could potentially be an option for induction of remission in biologic-experienced individuals with good initial clinical response to anti-TNF agents.

Complete colonoscopy for cancer screening requires cecal intubation. Failure to reach and examine the cecum may result in missed right colon pathology. We developed and validated a novel classification scheme for the endoscopic appearance of the normal appendiceal orifice (AO). We analyzed 1,456 AO images and grouped them into four categories based on distinguishing features: "diverticuloid," "umbilicoid," "crescent," and "linear." An expert panel classified the images and modified these categories, combining crescent and linear categories into "curvilinear." A 100-image subset was classified twice by a validation cohort consisting of gastroenterology faculty and fellows. Inter-observer agreement among the expert panel, and intra- and inter-observer agreement among the validation cohort were analyzed using Fleiss' kappa statistic. The distribution of AO images was 67% curvilinear, 19% umbilicoid, and 10% diverticuloid; 85 images (4%) were not classifiable. There was substantial inter-observer agreement among the expert panel (κ, 0.72). Inter-observer agreement among the validation cohort was moderate (κ, 0.53 and 0.55 for the first and second viewing, respectively). Intra-observer κ values among the validation cohort were 0.69 for the overall classification, 0.65 for diverticuloid, 0.70 for umbilicoid, and 0.70 for curvilinear, indicating substantial agreement. This simple, validated classification scheme for the endoscopic appearance of the normal AO can be used both as a research and clinical tool to measure endoscopic quality, improve cecal examination, and document successful cecal intubation.
