PURPOSE The aim of this study was to compare survival in patients that underwent palliative resection treatment versus non-resection for incurable colorectal cancer (ICRC). METHODS The case records of 201 patients with ICRC between January 2000 and December 2009 were reviewed. Demographics, American Society of Anesthesiologists (ASA) score, carcinoembryonic antigen (CEA) level, the location o...

OBJECTIVE To analyze, through molecular biology, the diversity of the intestinal microbiota before and after resection of the ileocecal junction and reconstruction of intestinal transit with and without the creation of a neosphincter. METHODS Fourteen Wistar rats were divided into two groups: Group A (n = 7), submitted to resection of the ileocecal valve and end-to-end, single-layer ileocolic...

BACKGROUND The utility of lymph node mapping to improve staging in colon cancer is still under evaluation. Laparoscopic colectomy for colon cancer has been validated in multi-centric trials. This study assessed the feasibility and technical aspects of lymph node mapping in laparoscopic colectomy for colon cancer. METHODS A total of 42 patients with histologically proven colon cancer were stud...

A 36-year-old woman presented with a palpable tender mass at the left lower quadrant of the abdomen. She had suffered from constipation for five years and had a previous history of intrauterine device-use for one year. Preoperative barium enema and abdominopelvic CT showed a compatible finding of rectosigmoid colon cancer or left ovary cancer. She underwent segmental resection of the sigmoid co...

The aim of this pilot study was to assess the feasibility of using computed virtual chromoendoscopy with the flexible spectral imaging color enhancement (FICE) for colon neoplasia screening. A modified back-to-back colonoscopy using FICE and white light in the right-sided colon was conducted prospectively for the consecutive patients attending for the postoperative (sigmoidectomy or anterior re...

Diabetes mellitus may affect the gastrointestinal tract possibly as a result of autonomic neuropathy. Here we present a 68-year-old male with non-insulin-dependent diabetes mellitus who presented with prolonged watery diarrhea and in whom imaging studies demonstrated ischemic colitis of the left colon. Resection of the affected colon resulted in sustained disappearance of symptoms.

A female patient was admitted to our hospital with sigmoid colon perforation caused by migrated biliary plastic stent, which was placed 2 months ago for the treatment of choledocholithiasis. The patient underwent sigmoid colon resection with primary anastomosis and was discharged on seventh postoperative day in good general condition.

BACKGROUND Adult large bowel obstruction is an infrequent cause of acute obstruction in Africa and India. The cause of obstruction varies between regions of the world. Current controversy concerns the surgical management of the acutely obstructed left colon. MATERIALS AND METHODS This is a prospective study of adult patients with acute large bowel obstruction over a 6-year period. The diagnos...

INTRODUCTION Colo-colic intussusception is extremely rare in adults and few cases have been described secondary to a lypomatous polyp. CASE REPORT We present the case of a 50-year old man with chronic abdominal pain who was diagnosed a colo-colic intussusception secondary to a lipoma of the left colon. The patient underwent laparoscopic resection of the splenic flexure without reduction, whic...

We experienced 3 cases of manometry-induced colon perforation. A 75-year-old man (case 1) underwent anorectal manometry (ARM) 3 years after radiotherapy for prostate cancer and a laparoscopic intersphincteric resection for rectal cancer. A 70-year-old man (case 2) underwent ARM 3 months after conventional neoadjuvant chemoradiotherapy and a laparoscopic low anterior resection for rectal cancer....
