    Upper gastrointestinal neoplasia in familial adenomatous polyposis: prevalence, endoscopic features and management
    (2019) CAMPOS, Fabio Guilherme; MARTINEZ, Augusto Real; SULBARAN, Marianny; BUSTAMANTE-LOPEZ, Leonardo Alfonso; SAFADE-RIBEIRO, Adriana Vaz
    Background: To evaluate the prevalence of upper gastrointestinal (GI) polyps in familial adenomatous polyposis (FAP), and to discuss current therapeutic recommendations. Methods: Clinical, endoscopic, histological and treatment data were retrieved from charts of 102 patients [1958-2016]. Duodenal adenomatosis was classified according to Spigelman stages. Results: this series comprised 59 women (57.8%) and 43 men (42.1%) with a median age of 32.3 years. Patients underwent 184 endoscopic procedures, the first at a median age of 35.9 years (range, 13-75 years). Fundic gastric polyps (n=31; 30.4%) prevailed in the stomach. While only 5 adenomas were found in the stomach, 33 patients (32.4%) presented duodenal ones. Advanced lesions (n=13; 12.7%) were detected in the stomach (n=2) and duodenum (n=11). During follow-up, Spigelman stages improved in 6 (12.2%) patients, remained unchanged in 25 (51.0%) and worsened in 18 (36.7%). Carcinomas were diagnosed in the stomach and duodenum (4 lesions each, 3.9%), at median ages of 50.2 and 55.0 years, respectively. Advanced lesions and carcinomas were managed through local or surgical resections. Severe complications occurred in only 2 patients (one death). Enteroscopy in 21 patients revealed jejunal adenomas in 12, 11 of whom also presented duodenal adenomas. Conclusions: There is a high prevalence of upper GI adenomas and cancer in FAP. There were diagnosed fundic gastric polyps (30.4%), duodenal (32.4%) and jejunal adenomas (11.8%), respectively. One third of duodenal polyps progressed slowly throughout the study. The rates of advanced gastroduodenal lesions (12.7%) and cancer (7.8%) raise the need for continuous surveillance during follow-up.

    Prevention of esophageal stricture after endoscopic submucosal dissection: a systematic review and meta-analysis
    (2016) OLIVEIRA, J. F.; MOURA, E. G. H.; BERNARDO, W. M.; IDE, E.; CHENG, S.; SULBARAN, M.; SANTOS, C. M. L.; SAKAI, P.
    Endoscopic submucosal dissection (ESD) of extensive superficial cancers of the esophagus may progress with high rates of postoperative stenosis, resulting in significantly decreased quality of life. Several therapies are performed to prevent this, but have not yet been compared in a systematic review. A systematic review of the literature and meta-analysis were performed using the MEDLINE, Embase, Cochrane, LILACS, Scopus, and CINAHL databases. Clinical trials and observational studies were searched from March 2014 to February 2015. Search terms included: endoscopy, ESD, esophageal stenosis, and esophageal stricture. Three retrospective and four prospective (three randomized) cohort studies were selected and involved 249 patients with superficial esophageal neoplasia who underwent ESD, at least two-thirds of the circumference. We grouped trials comparing different techniques to prevent esophagus stenosis post-ESD. We conducted different meta-analyses on randomized clinical trials (RCT), non-RCT, and global analysis. In RCT (three studies, n = 85), the preventive therapy decreased the risk of stenosis (risk difference = -0.36, 95 % CI -0.55 to -0.18, P = 0.0001). Two studies (one randomized and one non-randomized, n = 55) showed that preventative therapy lowered the average number of endoscopy dilatations (mean difference = -8.57, 95 % CI -13.88 to -3.25, P < 0.002). There were no significant differences in the three RCT studies (n = 85) in complication rates between patients with preventative therapy and those without (risk difference = 0.02, 95 % CI -0.09 to 0.14, P = 0.68). The use of preventive therapy after extensive ESD of the esophagus reduces the risk of stenosis and the number of endoscopic dilatations for resolution of stenosis without increasing the number of complications.
