ABSTRACT
Background: The usefulness of thiopurines has been poorly explored in pouchitis and other pouch disorders. Objective: To evaluate the effectiveness and safety of azathioprine as maintenance therapy in inflammatory pouch disorders. Design: This was a retrospective and multicentre study. Methods: We included patients diagnosed with inflammatory pouch disorders treated with azathioprine in monotherapy. Effectiveness was evaluated at 1 year and in the long term based on normalization of stool frequency, absence of pain, faecal urgency or fistula discharge (clinical remission), or any improvement in these symptoms (clinical response). Endoscopic response was evaluated using the Pouchitis Disease Activity Index (PDAI). Results: In all, 63 patients were included [54% males; median age, 49 (28-77) years]. The therapy was used to treat pouchitis (n = 37) or Crohn's disease of the pouch (n = 26). The rate of clinical response, remission and non-response at 12 months were 52%, 30% and 18%, respectively. After a median follow-up of 23 months (interquartile range 11-55), 19 patients (30%) were in clinical remission, and 45 (66%) stopped therapy. Endoscopic changes were evaluated in 19 cases. PDAI score decreased from 3 (range 2-4) to 1 (range 0-3). In all, 21 patients (33%) presented adverse events and 16 (25%) needed to stop therapy. Conclusion: Azathioprine may be effective in the long term for the treatment of inflammatory pouch disorders and could be included as a therapeutic option.
ABSTRACT
BACKGROUND AND AIMS: Small-bowel (SB) capsule endoscopy (CE) is a first-line procedure for exploring the SB. Endoscopic GI PlacemenT (EGIPT) of SB CE is sometimes necessary. Although experience with EGIPT is considerable in pediatric populations, we aimed to describe the safety, efficacy, and outcomes of EGIPT of SB CE in adult patients. METHODS: The international CApsule endoscopy REsearch (iCARE) group set up a retrospective multicenter study. Patients over age 18 years who underwent EGIPT of SB CE before May 2022 were included. Data were collected from medical records and capsule recordings. The primary endpoint was the technical success rate of the EGIPT procedures. RESULTS: Of 39,565 patients from 29 centers, 630 (1.6%) were included (mean age, 62.5 years; 55.9% women). The technical success of EGIPT was achieved in 610 procedures (96.8%). Anesthesia (moderate to deep sedation or general anesthesia) and centers with intermediate or high procedure loads were independent factors of technical success. Severe adverse events occurred in 3 patients (.5%). When technically successful, EGIPT was associated with a high SB CE completion rate (84.4%) and with a substantial diagnostic yield (61.1%). The completion rate was significantly higher when the capsule was delivered in the SB compared with when it was delivered in the stomach. CONCLUSIONS: EGIPT of SB CE is highly feasible and safe, with a high completion rate and diagnostic yield. When indicated, it should be performed with patients under anesthesia, and the capsule should be delivered in the duodenum rather than the stomach for better SB examination outcomes.

BACKGROUND: Capsule endoscopy (CE) has become a widespread modality for non-invasive evaluation of the gastrointestinal (GI) tract, with several CE models having been developed throughout the years. The aim of this systematic review and meta-analysis is to evaluate performance measures such as completion, detection and retention rates of CE. METHODS: Literature through to August 2021 was screened for articles regarding all capsule types: small bowel, double-headed capsule for the colon or PillCam®Crohn's capsule, magnetically-controlled capsule endoscopy, esophageal capsule and patency capsule. Primary outcomes included detection rate (DR), completion rate (CR) and capsule retention rate (RR). DR, CR and RR were also analyzed in relation to indications such as obscure GI bleeding (OGIB), known/suspected Crohn's disease (CD), celiac disease (CeD), neoplastic lesions (NL) and clinical symptoms (CS). RESULTS: 328 original articles involving 86,930 patients who underwent CE were included. OGIB was the most common indication (n = 44,750), followed by CS (n = 17,897), CD (n = 11,299), NL (n = 4989) and CeD (n = 947). The most used capsule type was small bowel CE in 236 studies. DR, CR and RR for all indications were 59%, 89.6% and 2%, respectively. According to specific indications: DR were 55%, 66%, 63%, 52% and 62%; CR were 90.6%, 86.5%, 78.2%, 94% and 92.8%; and RR were 2%, 4%, 1%, 6% and 2%. CONCLUSIONS: Pooled DR, CR and RR are acceptable for all capsule types. OGIB is the most common indication for CE. Technological advancements have expanded the scope of CE devices in detecting GI pathology with acceptable rates for a complete examination.

Introducción: Conocer la historia natural de la colitis ulcerosa (CU) es esencial para entender la evolución de la enfermedad, evaluar el impacto de las distintas estrategias terapéuticas e identificar factores de mal pronóstico. Uno de los aspectos más relevantes, en este sentido, es la necesidad de cirugía.Objetivos: Analizar la tasa de incidencia de colectomía (TIC) desde el diagnóstico hasta el fin de seguimiento (31 de diciembre del 2017) e identificar factores predictivos de colectomía.Material y métodos: Estudio retrospectivo que incluye los pacientes con diagnóstico definitivo (DD) de CU o colitis inclasificable (CI) en la cohorte Navarra 2001 a 2003.Resultados: Incluimos 174 pacientes con DD de CU (E2 42,8% - E3 26,6%) y cinco de CI: 44,1% mujeres, mediana edad 39,2 años (rango siete a 88), mediana de seguimiento 15,7 años. Se intervienen ocho pacientes (TIC tres colectomías/103pac/a): tres al debut (< 1 mes), dos en los primeros dos años, dos a los cinco años y uno a los 12 años de evolución. Todos habían recibido esteroides, cinco inmunomoduladores y dos biológicos. En siete (87%) la cirugía fue urgente y la indicación, megacolon en tres (37,5%), brote grave en tres (37,5%) y fallo a tratamiento médico en dos (25%). En cinco casos (62,5%) se realizó un reservorio ileoanal y en tres una ileostomía definitiva. En el análisis univariante, los pacientes con pérdida > 5 kg e ingreso al debut presentaron una menor supervivencia libre de colectomía.Conclusiones: En nuestra serie, las tasas de colectomía son más bajas que las comunicadas habitualmente, mayoritariamente se realizan en los primeros cinco años de evolución y se indican con carácter urgente

BACKGROUND: Capsule endoscopy (SBCE) has developed a relevant role in patients with established Crohn's Disease (CD). However, evaluation of the impact in clinical management has been scarce. AIMS: To evaluate therapeutic impact of SBCE in an 11-year real-life cohort of known CD patients. METHODS: Retrospective single center study including all patients with established CD submitted to SBCE procedure from 01/01/2008 to 31/12/2019. Patency capsule was used in selected patients. Small bowel mucosal inflammation was quantified using Lewis score. Therapeutic impact was defined as a change in CD-related treatment recommended based on SBCE results. Patients were assigned to four groups regarding SBCE indication: staging, flare, post-op and remission. RESULTS: From the 432 SBCE performed 87.5% were conclusive. Active disease was present in 63.7 of patients; 41.6% mild inflammation and 21.9% moderate-to-severe activity. A change of management was guided by SBCE in 51.3% of procedures: 199 (46.1%) escalation and 23 (5.3%) de-escalation, with significant changes in all groups. Escalation increased with disease activity: 57.8% in mild and 89.5% in moderate-to-severe disease. De-escalation was conducted in 13.9% procedures with mucosal healing and 1.1% with mild disease. CONCLUSION: SBCE is a useful tool for guiding therapeutic management in CD patients both for treatment escalation and de-escalation.

In recent years, panintestinal capsule endoscopy (PCE) with double-headed capsules has been used to perform complete, single-sitting exploration of both small bowel and colon in different clinical conditions. Double-headed capsules for colonic examination (CCE) have been exploited first in this setting, followed by newer generations of capsules (i.e. PillCam Crohn, PCC) specifically engineered for this purpose. The aim of this study was to evaluate the feasibility of PCE in the form of a systematic review. We performed a comprehensive literature search to identify papers in which CE was specifically used for a PCE of the gastrointestinal tract. Data on CE, bowel preparation regimen, rate of cleanliness and completeness, and data on transit times were analyzed. The primary outcome was to assess the feasibility of a whole-gut exploration with CE. Sixteen (n = 16) studies including 915 CE procedures with CCE1 (n = 134), CCE2 (n = 357) and PCC (n = 424) were included. 13/16 studies were performed in the setting of Crohn's disease. Cleanliness and completeness rates were acceptable in all studies, ranging from 63.9% and 68.6% to 100%, respectively. In conclusion, PCE is a feasible technique, although further structured studies are needed to explore its full potential.

BACKGROUND: Endoscopically defined mucosal healing in Crohn's disease is associated with improved outcomes. Panenteric capsule endoscopy enables a single non-invasive assessment of small and large bowel mucosal inflammation. AIMS AND METHODS: This multicentre observational study of patients with suspected and established Crohn's disease examined the feasibility, safety and impact on patient outcomes of panenteric capsule endoscopy in routine clinical practice. The potential role in assessment of disease severity and extent by a comparison with existing clinical and biochemical markers is examined. RESULTS: Panenteric capsule endoscopy was performed on 93 patients (71 with established and 22 with suspected Crohn's disease). A complete examination occurred in 85% (79/93). Two cases (2.8%) of capsule retention occurred in patients with established Crohn's disease. Panenteric capsule resulted in management change in 38.7% (36/93) patients, including 64.6% (32/48) of those with an established diagnosis whose disease was active, and all three patients with newly diagnosed Crohn's disease. Montreal classification was upstaged in 33.8% of patients with established Crohn's disease and mucosal healing was demonstrated in 15.5%. Proximal small bowel disease upstaged disease in 12.7% and predicted escalation of therapy (odds ratio 40.3, 95% confidence interval 3.6-450.2). Raised C-reactive protein and faecal calprotectin were poorly sensitive in detecting active disease (0.48 and 0.59 respectively). CONCLUSIONS: Panenteric capsule endoscopy was feasible in routine practice and the ability to detect proximal small bowel disease may allow better estimation of prognosis and guide treatment intensification. Panenteric capsule endoscopy may be a suitable non-invasive endoscopic investigation in determining disease activity and supporting management decisions.

BACKGROUND & AIMS: It is not clear whether closure of mucosal defects with clips after colonic endoscopic mucosal resection (EMR) prevents delayed bleeding, although it seems to have no protective effects when risk is low. We performed a randomized trial to evaluate the efficacy of complete clip closure of large (≥2 cm) nonpedunculated colorectal lesions after EMR in patients with an estimated average or high risk of delayed bleeding. METHODS: We performed a single-blind trial at 11 hospitals in Spain from May 2016 through June 2018, including 235 consecutive patients who underwent EMR for large nonpedunculated colorectal lesions with an average or high risk of delayed bleeding (based on Spanish Endoscopy Society Endoscopic Resection Group score). Participants were randomly assigned to groups that received closure of the scar with 11-mm through-the-scope clips (treated, n = 119) or no clip (control, n = 116). The primary outcome was proportion of patients in each group with delayed bleeding, defined as evident hematochezia that required medical intervention within 15 days after colonoscopy. RESULTS: In the clip group, complete closure was achieved in 68 (57%) cases, with partial closure in 33 (28%) cases and failure to close in 18 (15%) cases. Delayed bleeding occurred in 14 (12.1%) patients in the control group and in 6 (5%) patients in the clip group (absolute risk difference, reduction of 7% in the clip group; 95% confidence interval, -14.7% to 0.3%). After completion of the clip closure, there was only 1 (1.5%) case of delayed bleeding (absolute risk difference, reduction of 10.6%; 95% confidence interval, -4.3% to 17.9%). CONCLUSIONS: In a randomized trial of patients with large nonpedunculated colorectal lesions undergoing EMR, we found that clip closure of mucosal defects in patients with a risk of bleeding can be a challenge, but also reduces delayed bleeding. Prevention of delayed bleeding required complete clip closure. ClinicalTrials.gov ID: NCT02765022.
