Primary schwannoma of the large intestine is an extremely rare neoplasm. Here, we report two cases of colonic schwannoma confirmed pathologically after laparoscopic resection. A 52-year-old female and a 59-year-old female were referred by their general practitioners to our coloproctologic clinic for further evaluation and management of colonic submucosal masses. Colonoscopies performed in our i...

To the Editor, We present a case of 58-year-old man who had suffered from nausea and vomiting with intermittent right lower abdominal pain that morning. He had no known systemic disease and earlier had been quite well. He had had tarry stool for one month but no loss of body weight. Physical examination revealed muscle guarding and tenderness over the right lower abdomen, without rebound pain. ...

BACKGROUND Single-port laparoscopic surgery is a new technique that leaves no visible scar. This new technique has generated strong interest among surgeons worldwide. However, single-port laparoscopic colon surgery has not yet been standardized. Our aim in this study was to evaluate the feasibility of single-port laparoscopic colectomy compared with conventional laparoscopic colectomy for colon...

Penetration and abscess formation in an adjacent parenchymal organ as presentation of a colon cancer is very uncommon. We report a rare case of pyogenic liver abscess as the first manifestation of an infiltrative and penetrating hepatic flexure colon carcinoma without liver metastases. A 50-year-old woman was admitted with right abdominal pain, fever and chills. The initial diagnosis was a pyog...

BACKGROUND The purpose of this study was to compare short-term clinical outcomes of ileocolonic functional end-to-end anastomosis (FEEA) and end-to-side anastomosis (ESA) following resection of the right colon for cancer. METHODS We enrolled 379 patients who underwent ileocolonic anastomosis following resection of the right colon for cancer by a single surgeon, from January 2009 through June ...

BACKGROUND/AIMS Colon transit time (CTT) is a useful diagnostic tool in chronic constipation, but requires good patient compliance. We analyzed the correlation between the gas volume score (GVS) and CTT in patients with chronic constipation. METHODS The study included 145 consecutive patients (65 men) with chronic constipation. The primary outcome was the correlation be-tween the colon GVS an...

Simultaneous laparoscopy-assisted resection for synchronous stomach and colon cancers has been reported frequently; however, robot-assisted gastrectomy and colectomy for these conditions are rarely reported. We report the successful use of robotic surgery for synchronous cancers of the stomach and colon. A 71-year-old woman with no specific medical history was diagnosed with early gastric cance...
