RESUMO
INTRODUCTION: Endoscopic ultrasonography (EUS) is the gold standard technique in loco-regional staging of gastric adenocarcinoma (GAC). Nevertheless, the introduction of multidetector-row computed tomography (MDCT) allows accurate studies to be performed. OBJECTIVE: To compare the diagnostic yield of EUS and MDCT in loco-regional preoperative staging of gastric adenocarcinoma. MATERIAL AND METHODS: This was a retrospective and comparative study of all surgical patients with GAC and preoperative staging by EUS and 64-row MDCT. The results for each case were compared with the histological data. RESULTS: Seventy seven surgical patients with GAC were identified and forty two had a complete preoperative staging and were finally included in the study. With regard to overall accuracy of T staging, EUS was superior to MDCT (62% vs 50%). In a subanalysis of early stages (T1-T2) and advanced stages (T3-T4), accuracy and sensitivity (S) were higher for EUS than for MDTC (83.3% vs 64.29% and 84.4% vs 59.5% respectively), although this did not reach statistical significance. The overall accuracy and sensitivity of EUS for N staging was lower than that for MDCT, although neither comparison reached statistical significance (57% vs 64% and 29% vs 55%). CONCLUSION: EUS diagnostic yield is similar to new MDCT with regard to T and N preoperative staging of GAC. Nevertheless, both techniques should be considered as complementary until more extensive and randomized studies can confirm these results.

OBJECTIVE: Endoscopic recurrence in Crohns disease occurs in up to 80% of patients during the first year after surgery. Due to this, these patients need close monitoring. Faecal calprotectin has been proposed to be used as a non-invasive marker to monitor inflammatory activity. Up to now the use of faecal markers in endoscopic recurrence has been scarcely studied and with contradictory results. MATERIAL AND METHODS: This was a cross-sectional observational study of diagnostic validity. It included all patients with Crohns disease (CD) and ileocolic resection retrospectively who had had an ileocolonoscopy and a determination of faecal calprotectin before this colonoscopy, from 2007 to 2015. RESULTS: Ninety-seven patients were included. We observed that the mean value of faecal calprotectin increased as the Rutgeerts score increased. The variable of that most statistical significance obtained in bivariate analysis was faecal calprotectin (p < 0.0001). Area under curve (AUC) of faecal calprotectin in endoscopic recurrence was 0.74 (95% CI: 0.644-0.842), and an optimal cut-off of 60 mcrgr/gr, obtained a score of 0.45 using Youden test. This indicated that calprotectin would have 88% Sensitivity and 58% Specificity in detecting any recurrence, the NPV was approximately 83,9%. None of the other variables studied had a significant correlation. CONCLUSION: Faecal calprotectin predicts endoscopic recurrence in CD patients who have gone through surgery, however the cut-off point is still a problem so we cannot recommend calprotectin as a substitute of colonoscopy for CD monitoring and treatment adjustment.

IBD flares or new diagnosis in patients receiving anti-TNF because of other diseases than IBD are rare events but the possibility of a paradoxical reaction must be considered as with psoriasis or uveitis. We present a patient suffering from RA who had a new CD onset after a two-year adalimumab treatment.

Background and study aims Rates of new dysplastic lesions or cancer progression after first dye chromoendoscopy in the era of high-definition endoscopy have yet to be determined. Patients and methods A multicenter, population-based, retrospective cohort study was performed in seven hospitals in Spain. Patients with inflammatory bowel disease and fully resected (R0) dysplastic colon lesions under surveillance with high-definition dye-based chromoendoscopy were sequentially enrolled between February 2011 and June 2017, with a minimum endoscopic follow-up of 36 months. The aim was to assess the incidence of developing more advanced metachronous neoplasia by analyzing possible associated risk factors. Results The study sample included 99 patients and 148 index lesions (145 low-grade dysplasia lesions and three high-grade dysplasia [HGD] lesions with a mean follow-up of 48.76 months [IQR: 36.34-67.15]). The overall incidence of new dysplastic lesions was 0.23 per 100 patient-years, 1.15 per 100 patients at 5 years and 2.29 per 100 patients at 10 years. A history of dysplasia was associated with a higher risk of developing any grade of dysplasia during follow-up ( P â=â0.025), whereas left colon lesions were associated with a lower risk ( P â=â0.043). The incidence of more advanced lesions at 1 year and 10 years was 1â% and 14â% respectively, with lesion sizeâ>â1âcm being a risk factor ( P â=â0.041). One of the eight patients (13â%) with HGD lesions developed colorectal cancer during follow-up. Conclusions The risk of dysplasia progressing to advanced neoplasia and, specifically, the risk of new neoplastic lesions after endoscopic resection of colitis-associated dysplasia, are both very low.
RESUMO
OBJECTIVES: compare the intensity of pain experienced after colonoscopy with air or with CO2 and evaluate the safety of CO2 in colonoscopies performed with moderate/deep sedation. MATERIALS AND METHODS: individuals undergoing ambulatory colonoscopy without exclusion criteria (severe respiratory disease, morbid obesity) were randomized in air or CO2 group. We recorded different variables prior to, during and upon completion of the colonoscopy, performing monitoring using pulse oximetry and capnography. Each patient rated, using a visual numeric scale, the intensity of post-colonoscopy pain at different moments. RESULTS: 141 individuals in the air group (sex M/F 63/78, age 24-83) and the CO2 group (sex M/F 59/70, age 24-82). No significant differences existed in the recorded variables in both groups except for the greater number of explorations performed by an endoscopist in training (TE) in the air group compared to those by a more experienced endoscopist (SE). CO2 in expired air, episodes of oxygen desaturation and of apnoea and dose of propofol, of midazolam were similar in both groups. No episodes of hypercapnea or any complication requiring cardiopulmonary resuscitation measures were recorded. The pain in the air group was significantly higher at 15 minutes and at 1, 3 and 6 hours after the endoscopy, equalising at 24 hours. After multivariant adjustment for type of doctor (TE vs. SE) the differences observed in pain intensity for each group were maintained. CONCLUSIONS: a) the use of CO2 in colonoscopy causes significantly less pain in the first 6 hours after the procedure; b) its use in patients with moderate/deep sedation is safe; and c) performance of the endoscopic technique is not modified, nor are times reduced.

Diffuse intestinal ganglioneuromatosis is a hamartomatous polyposis characterized by a disseminated, intramural or transmural proliferation of neural elements involving the enteric plexuses. It has been associated with MEN II, neurofibromatosis type 1 and hamartomatous polyposis associated with phosphatase and tensin homolog mutation. We report the case of a female patient with a history of a breast and endometrial tumor who presented in a colonoscopy performed for rectal bleeding diffuse ganglioneuromatosis, which oriented the search for other characteristic findings of Cowden syndrome given the personal history of the patient. The presence of an esophagogastric polyposis was also noted. Cowden syndrome is characterized by skin lesions, but it is rarely diagnosed by these lesions, because they are usually overlooked. Intestinal polyposis is not a major diagnostic criterion but it is very useful for early diagnosis. The combination of colonic polyposis and glucogenic acanthosis should orient the diagnosis to Cowden syndrome.
