OBJECTIVE Using meta-analytical techniques, the study compared postoperative adverse events and functional outcomes of stapled versus hand-sewn ileal pouch-anal anastomosis (IPAA) following restorative proctocolectomy. BACKGROUND The choice of mucosectomy and hand-sewn versus stapled pouch-anal anastomosis has been a subject of debate with no clear consensus as to which method provides better...

BACKGROUND Idiopathic esophageal achalasia is an inflammatory disease of unknown origin, characterized by aperistalsis of the esophageal body and failure of the lower esophageal sphincter in response to swallowing, with consequent dysphagia. AIM To demonstrate the results of surgical therapy in these patients, evaluating the occurred local and systemic complications. METHODS Were studied re...

TEM is an endoscopic method of operating tumors up to 18 cm of the anal verge. It enables procedures from a simple mucosectomy to en-block excisions of the whole thickness of the rectal wall. We present a study in which we evaluated surgical morbidity, mortality and recurrence rate of rectal tumors in patients treated with TEM from July 2007, up to the end of March 2014. In our Department 129 p...

Patients and methods During the 1997–2007 decade, 57 cases of esophageal neoplasm were observed, of which 15 patients whose age range was 70–85 years, 11 males and 4 females, all presented with associated cardiovascular, respiratory and metabolic pathologies that would not allow the possibility of surgical approach. Patients enrolled in the current study contain in their clinical history severa...

Resection of a non-lifting large laterally spreading flat colonic polyp can be challenging. A 44-year-old Hispanic woman with a history of hereditary non-polyposis colorectal cancer syndrome (HNPCC) was referred for removal of a laterally spreading polyp. Colonoscopy showed a 2-cm laterally spreading flat polyp in the proximal transverse colon (▶Video1; ▶Fig. 1a). Submucosal injection was perfo...

BACKGROUND There are situations in which the specimens obtained after endoscopic mucosal resection of superficial adenocarcinoma arising from Barrett's esophagus are not adequate for histopathological assessment of the margins. In these cases, immunohistochemistry might be an useful tool for predicting cancer recurrence. AIM To evaluate the value of p53 and Ki-67 immunohistochemistry in predi...
