The rebleeding rate in patients evaluated for obscure gastrointestinal bleeding after negative small bowel findings by device assisted enteroscopy.

BACKGROUND: data on the long-term outcome of patients with obscure gastrointestinal bleeding (OGIB) with positive small bowel findings in capsule endoscopy but negative small bowel findings in device-assisted enteroscopy are scarce. OBJECTIVE: this study aimed to evaluate the rebleeding rate and time to rebleed in patients with no small bowel findings in enteroscopy, after a positive capsule endoscopy in the setting of OGIB. Baseline predictors for rebleeding were assessed. METHODS: a retrospective double-center study was performed, including patients with OGIB with positive findings by capsule endoscopy and negative small bowel findings by enteroscopy. RESULTS: thirty-five patients were included. Rebleeding occurred in 40 % of patients during a median follow-up of 27 months. Further evaluation in patients with a rebleed was performed in 85.7 %, leading to a final diagnosis in 78.6 %. The rebleeding rate increased progressively over time, from 17.2 % at one month to 54.4 % at four years. Overt bleeding at the time of the first episode was a predictor of rebleeding (p = 0.03) according to the multivariate analysis. This was 50 % at one year compared with 21.8 % in patients with occult bleeding on admission. CONCLUSIONS: in obscure gastrointestinal bleeding, long-term follow-up and further evaluation may be considered after a positive capsule endoscopy. Even if there are no small bowel findings by device-assisted enteroscopy. The rebleeding rate in our study was 40 %, mainly in the presence of an overt bleeding on admission.

Duodeno-biliary obstruction in Peutz-Jeghers syndrome.

BACKGROUND: Peutz-Jeghers syndrome (PJS) is a pathology with autosomal dominant inheritance characterized by the presence of hamartomatous polyposis and mucocutaneous pigmentation. We present a case report from the Hospital General of Mexico. CLINICAL CASE: We present the case of a 28-year-old male. During physical examination we noted hyperpigmented dermatosis of the oral mucosa and lips. The same condition was seen in both palms. The condition evolved with intolerance to oral feeding and progressive obstructive jaundice. Panendoscopy reported pangastric sessile polyps, as well as being pylorus passable. In the second duodenal portion occupying the region of the ampoule of Vater was a sessile polyp that deformed the region. Exit of bile was not observed through the ampoule. Ultrasound and computed tomography of the abdomen corroborated dilatation of the extrahepatic biliary tract. Two endoprostheses were placed in the bile duct by endoscopic cholangiography, with improvement of biliary obstruction. Roux-en-Y astrojejunoanastomosis was performed because of obstruction of the duodenum by polyps between the second and third portion. Jejunal enterotomy was necessary because of the presence of intraluminal injury formed by a conglomerate of polyps. The patient had a satisfactory evolution. Pathological study reported hamartomatous polyps. CONCLUSIONS: Duodenal obstruction secondary to biliary tract obstruction is a rare manifestation associated with PJS. In these cases, the treatment of choice is polyp resection using endoscopic and/or surgical approach as well as management of the biliary tract obstruction.
