Early esophageal squamous cell carcinoma detected by esophageal iodine staining can be easily treated by endoscopic mucosectomy, and identifying its predictors is important in better selecting candidates to screen for this high-mortality cancer. The common etiologies of elevated mean corpuscular volume (MCV) and esophageal cancer, including folate deficiency, smoking, drinking and high acetalde...
OBJECTIVE to compare endoscopic and histopathologic features of superficial, elevated lesions with one or more centimeters in diameter, diagnosed by videocolonoscopy on the distal and proximal colon, and subjected to mucosal resection. METHODS we conducted a retrospective, cross-sectional, observational study involving 8,075 videocolonoscopies. From this total, we evaluated 166 mucosectomies ...
Surgery is no more alone in the scenario of gastric cancer treatment since many years. Although the encouraging results of adjuvant chemotherapy obtained in Japan with S-1 were not achieved in Western countries, a novel approach, after the results of MAGIC trial, published in 2006, has been introduced by means of perioperative, or just preoperative, chemotherapy in the West, with many trials on...
Intramural esophageal hematoma (IEH) is a rare but well-recognized endoscopic finding, which forms part of the spectrum of esophageal mucosal injuries [1,2]. It results from disruption of the vasculature within the submucosal plane of the esophageal wall. This leads to dissection of the submucosa by blood, which extends the length of the esophagus and causes intramural expansion and compression...
CONTEXT Differential diagnosis of hyperplastic vs adenomatous lesions is of crucial importance on the daily practice of colonoscopy. OBJECTIVES This study aimed at quantifying digital morphometric characteristics of colonoscopic images obtained with magnification and chromoscopy of three different types of colonic lesions: hyperplastic, adenomas and carcinomas, and the normal mucosa surroundi...
Colorectal surgeons are familiar with the ‘holy plane’ as the key to total mesorectal excision (TME). Although this has revolutionized the surgical treatment of rectal cancer1, another term should now be introduced into the surgical lexicon – the rectal ‘no man’s land’. This is the area of the distal rectum that lies within the pelvic floor musculature. It cannot usually be reached from the abd...
Restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis (IPAA) is the standard surgical treatment for ulcerative colitis (UC). Emergency colectomies are performed for fulminant colitis (ie, toxic megacolon, profuse bleeding, perforation, or sepsis). The RPC and IPAA involve manipulation of the proximal ileum, which may influence the essential physiological function of gut-associated...
