Kishi3, P. Sakai1, E. G. H. de Moura1, L. Bustamante-López2, M. Tomitão3, S. C. Nahas2, I. Cecconello2, A. V. Safatle-Ribeiro1ABSTRACT
Background and study aims 
To determine the clinical features associated with advanced duodenal and ampullary adenomas in familial adenomatous polyposis. Secondarily, we describe the prevalence and clinical significance of jejunal polyposis.

Patients and methods 
This is a single center, prospective study of 62 patients with familial adenomatous polyposis. Duodenal polyposis was classified according to Spigelman and ampullary adenomas were identified. Patients with Spi- gelman III and IV duodenal polyposis underwent balloon as- sisted enteroscopy. Predefined groups according to Spigel- man and presence or not of ampullary adenomas were related to the clinical variables:…

Background: In addition to the presence of neoplasia in the colon and rectum, patients with familial adenomatous polyposis (FAP) may develop numerous polyps and carcinoma within the upper gastrointestinal tract.

Methods: The aim of the present paper was to review the incidence advanced duodenal polyposis or cancer and their surgical outcomes. A retrospective review of patients’ records from our department was performed. Information was retrieved from a prospective collected data, including clinical (gender, age, family history), endoscopic [association with colorectal cancer (CRC), polyposis severity, age at diagnosis] and surgical management (age, time from the index surgery, type of procedure, morbidity). Duodenal adeno…

Prognostic factors affecting outcomes in multivisceral en bloc resection for colorectal cancer.Nahas CSR1, Nahas SC1, Ribeiro-Junior U1, Bustamante-Lopez L1, Marques CFS1, Pinto RA1, Imperiale AR1, Cotti GC1, Nahas WC2, Chade DC2, Piato DS3, Busnardo F4, Cecconello I1. Abstract OBJECTIVES::This study sought to determine the clinical and pathological factors associated with perioperative morbidity, mortality and oncological outcomes after multivisceral en bloc resection in patients with colorectal cancer. METHODS:: Between January 2009 and February 2014, 105 patients with primary colorectal cancer selected for multivisceral resection were identified from a prospective database. Clinical and pathological factors, perioperative morbidity and mortality and outcomes were obtained from medical records. Estimated local recurrence and overall survival were compared using the log-rank method, and Co…

Endoscopic colostomy with percutaneous colopexy: an animal feasibility study.

 2017 Apr;109(4):273-278. doi: 10.17235/reed.2017.4201/2016. Endoscopic colostomy with percutaneous colopexy: an animal feasibility study.Bustamante-Lopez LA1, Sulbaran M2, Nahas SC3, de Moura EG2, Nahas CS3, Marques CF3, Sakai C2, Cecconello I3, Sakai P2. Abstract BACKGROUND:Indications for colostomy in colorectal diseases are obstruction of the large bowel, such as in cancer, diverticular disease in the acute phase, post-radiotherapy enteritis, complex perirectal fistulas, anorectal trauma and severe anal incontinence. Some critically ill patients cannot tolerate an exploratory laparotomy, and laparoscopic assisted colostomy also requires general anesthesia. OBJECTIVE:To evaluate the feasibility, safety and efficacy of performing colostomy assisted by colonoscopy and percutaneous colopexy. MATERIALS AND METHODS:Five pigs underwent endoscopic assisted colostomy with percutaneous colopexy. Animals were evaluated in post-operative days 1, 2, 5 and 7…

Overtube-assisted enteroscopy and capsule endoscopy for the diagnosis of small-bowel polyps and tumors: a systematic review and meta-analysis.

 2016 Feb;4(2):E151-63. doi: 10.1055/s-0041-108261. Epub 2016 Jan 11. Overtube-assisted enteroscopy and capsule endoscopy for the diagnosis of small-bowel polyps and tumors: a systematic review and meta-analysis.Sulbaran M1, de Moura E1, Bernardo W1, Morais C1, Oliveira J1, Bustamante-Lopez L2, Sakai P1, Mönkemüller K3, Safatle-Ribeiro A1. Abstract BACKGROUND AND STUDY AIMS:Several studies have evaluated the utility of double-balloon enteroscopy (DBE) and capsule endoscopy (CE) for patients with small-bowel disease showing inconsistent results. The aim of this study was to determine the sensitivity and specificity of overtube-assisted enteroscopy (OAE) as well as the diagnostic concordance between OAE and CE for small-bowel polyps and tumors. PATIENTS AND METHODS:We conducted a systematic review and meta-analysis of studies in which the results of OAE were compared with the results of CE for the evaluation of small-bowel polyps and tumors. When data f…
