Abstract
INTRODUCTION retention is the most common adverse event of the small bowel capsule endoscopy procedure. Patency capsule (Medtronic, Dublin, Ireland) and magnetic resonance enterography are two diagnostic methods that can prevent small bowel capsule endoscopy retention. The aim of this study was to evaluate the predictive value of these two diagnostic methods. MATERIAL AND METHODS a prospective, comparative and observational study was performed in patients with established Crohn's disease. All patients had undergone magnetic resonance enterography and patency capsule procedures. If the patency capsule was not retained, the patient underwent a small bowel capsule endoscopy; otherwise, double balloon enteroscopy was performed to locate the stenosis. Magnetic resonance enterography predictive criteria for retention were analyzed in all cases. Sensitivity, specificity, positive predictive value and negative predictive value of the patency capsule and magnetic resonance enterography compared to small bowel capsule endoscopy or double balloon enteroscopy were calculated. RESULTS forty patients were included (24 female, 55 ± 13 years old). Retention criteria with capsule endoscopy or double balloon enteroscopy were found in six patients, agreeing in five cases with patency capsule and in three cases with magnetic resonance enterography. Sensitivity, specificity, positive predictive value, negative predictive value and Kappa coefficient for predicting retention with the patency capsule were 83 %, 100 %, 100 % and 97 %, respectively, and 50 %, 91 %, 50 % and 91 %, respectively, with magnetic resonance enterography. CONCLUSIONS patency capsule has a higher sensitivity and positive predictive value than magnetic resonance enterography for preventing small bowel capsule endoscopy retention in Crohn's disease patients.

Abstract
INTRODUCTION The diagnostic yield (DY) of small-bowel capsule endoscopy (SBCE) varies considerably according to its indication. Some strategies have been used to increase DY with varying results. The intention of this study was to identify whether evaluation of the SBCE recordings by a second reviewer can increase DY and change patient management. METHODS One hundred SBCEs with different indications, already read by an endoscopist were read by a second blinded endoscopist. When the results of the 2 readings were different, the images were discussed by the endoscopists; if no consensus was reached, they took the opinion of a third endoscopist into account. All the participating endoscopists had experience in reading SBCEs (i.e., >50 per year). The SBCE findings were divided into positive (vascular lesions, ulcers, and tumors), equivocal (erosions or red spots), and negative. The interobserver agreement and the increase in DY were assessed as well as the percentage of false-negatives (FNs) in the first evaluation. RESULTS The indications for SBCE were small-bowel bleeding (SBB) in 48 cases, Crohn's disease (CD) in 30, and other causes (iron-deficiency anemia, small-bowel tumors, and diarrhea) in 22. There was substantial interobserver agreement between evaluations (κ = 0.79). The findings in the first evaluation were positive in 60%, equivocal in 20% and, negative in 20%. In the second evaluation, 66% were positive, 18% were equivocal, and 16% were negative. The increase in DY with the second reading was 6% (p = 0.380), i.e., 6.3% for SBB, 4.4% for CD and 9.2% for other indications, resulting in a change in management of 4% of the patients. FNs in the first SBCE reading were found in 4% of the SBCEs. DISCUSSION A second evaluation of the SBCE recordings identified significant pathology that the first evaluation had missed, resulting in a nonsignificant 6% increase in DY and a change in the management of 4% of the patients.

Abstract
INTRODUCTION AND AIMS The patency capsule is an effective diagnostic method for preventing video capsule retention in the small bowel during capsule endoscopy. The most frequently associated complication when using the patency capsule is symptomatic retention. The aim of the present study was to evaluate the effectiveness and safety of patency capsules administered to patients at a tertiary care hospital center. MATERIALS AND METHODS A retrospective observational study was conducted that included all the patients with confirmed Crohn's disease that were administered a patency capsule, within the time frame of January 2019 and December 2020. PC diagnostic yield, sensitivity, specificity, positive predictive value, and negative predictive value were evaluated, in relation to capsule endoscopy and double-balloon endoscopy findings. Complications associated with the patency capsule were also identified. RESULTS Thirty patients were included, in whom the patency capsule had 83% sensitivity, 100% specificity, 100% positive predictive value, and 96% negative predictive value, with a diagnostic yield of 96.7%. There was one complication (3.3%) and it resolved spontaneously. CONCLUSIONS The patency capsule is a safe and effective method for reducing video capsule retention during capsule endoscopy in patients with Crohn's disease.

Abstract
INTRODUCTION AND AIM Graft-versus-host disease (GvHD) is a complication of hematopoietic cell transplantation, and the small bowel is one of the main targets in the gastrointestinal tract. Capsule endoscopy is a safe procedure and can be useful in the diagnosis of GvHD. The aim of the present study was to compare the diagnostic yield of capsule endoscopy with the histopathologic findings in GvHD. MATERIALS AND METHODS A retrospective diagnostic test study included all the patients with suspected GvHD that underwent gastroscopy and colonoscopy, with histopathologic evaluation of the biopsies taken, and capsule endoscopy, within the time frame of July 2015 and July 2019. Capsule endoscopy findings were compared with the histopathologic diagnosis, considered the gold standard. RESULTS Twenty-one patients with GvHD (7 [33%] women; 37 ± 11.9 years of age) were included, 20 (95%) of whom had acute GvHD. The median gastric transit time of the capsule was 55 minutes (20-113) and the median small bowel transit time was 261 minutes (238-434). The entire small bowel was visualized through capsule endoscopy in 17 cases (80.95%). The histopathologic findings and capsule endoscopy findings resulted in the diagnosis of GvHD in 17 and 16 cases, respectively. There was agreement between the histopathologic and capsule endoscopy findings in 18 cases (15 positive and 3 negative). Sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic yield of capsule endoscopy were 88%, 75%, 94%, 60%, and 85%, respectively. CONCLUSIONS Capsule endoscopy is a safe tool for the diagnosis of GvHD, with high sensitivity and positive predictive value, as well as moderate agreement with histopathologic findings.

Abstract
BACKGROUND Helicobacter pylori (Hp) is recognized as a type 1 carcinogen for gastric cancer associated with pre-neoplastic lesions (atrophy and intestinal metaplasia [IM]). Its relation with p53, which intervenes in the cell cycle, has had contradictory results. AIMS To analyze p53 expression in gastric mucosa and its relation with Hp infection. METHODS A 3-month prospective, observational, cross-sectional study was conducted. Patients that had no evidence of acute or clinically significant gastric pathology had biopsies taken according to the Sydney system at the Hospital Juárez de México and the histopathologic studies were done at the Hospital Español de México. RESULTS Hp prevalence was 32.7% in 104 patients. There were no cases of atrophy or dysplasia. A total of 91% of the infected patients were positive for p53. Of the non-infected patients, 14% were positive for p53 and 60% of them had IM. Of the IM patients, 75% presented with positive p53. Of the patients without IM, 31 presented with positive p53, and Hp was positive in 85% of them. There was association between Hp and p53 and between p53 and IM (P<.0001 and P<.0006, respectively). CONCLUSIONS Significant association was shown between Hp and p53 expression, even in patients with pre-neoplastic lesions that no longer presented with Hp. Given that the identification of pre-neoplastic lesions is important for the prevention of cancer, immunohistochemistry could benefit routine biopsy carried out during endoscopy for the detection of Hp, by identifying patients with expression of the important oncogene regulator, p53.
