We report a case of perivascular epithelioid cell tumor arising in the rectum of a 55-year-old woman. The tumor was treated by transanal endoscopic microsurgery. After 1 year follow-up, the patient is alive with no radiologic or endoscopic evidence of recurrence. Perivascular epithelioid cell tumor is a rare mesenchymal tumor characterized by co-expression(More)
Crohn’s disease (CD) is routinely evaluated using clinical symptoms, laboratory variables, and the CD activity index (CDAI). However, clinical parameters are often nonspecific and do not precisely reflect the actual activity of CD small-intestinal lesions. The purposes of this prospective study were to compare color Doppler ultrasound (US) findings with(More)
Colorectal flat-type tumors include laterally spreading tumors (LSTs) and flat depressed‑type tumors. The former of which shows a predominant lateral spreading growth rather than an invasive growth. The present study examined the morphological characteristics of LSTs, in comparison with polypoid‑ or flat depressed‑type tumors, along with the expression of(More)
OBJECTIVE Laparoscopic reduction of appendicocecal intussusception due to mucinous cystadenoma is herein described. METHODS A 32-year-old female had intermittent abdominal pain and nonbloody diarrhea. The preoperative diagnosis was intussusception of the colon with a benign tumor by CT-scan findings. RESULTS Laparoscopic reduction of intussusception and(More)
BACKGROUND To investigate the effect of obesity on open gastrectomy with D2 lymph-node dissection. METHODS Between January 2005 and March 2007, 100 patients with preoperatively diagnosed gastric cancer who underwent open gastrectomy with D2 lymph-node dissection were enrolled in this study. Of these, 61 patients underwent open distal gastrectomy (ODG) and(More)
BACKGROUND Postoperative pancreas fistula (POPF) is a major complication after total gastrectomy with splenectomy. We retrospectively studied the effects of upper abdominal shape on the development of POPF after gastrectomy. METHODS Fifty patients who underwent total gastrectomy with splenectomy were studied. The maximum vertical distance measured by(More)
A 67-year-old man was referred to our hospital with suspicion of rectal tumor, hilar tumor, and urinary tumor. Colonoscopic findings were intermittent nodular lesions with redness which were atypical to primary rectal cancer. Endoscopic retrograde cholangiopancreatography showed narrowing of the bilateral intrahepatic bile duct. However, the findings were(More)
BACKGROUND The guidelines established by the National Comprehensive Cancer Network do not describe mucinous histology as a clinical factor that should influence the therapeutic algorithm. However, previous studies show conflicting results regarding the prognosis of colorectal mucinous adenocarcinoma. In this study, we described the clinicopathological(More)
BACKGROUND AND OBJECTIVES Laparoscopic-assisted colectomy for colon and rectal cancer causes less surgical trauma than does open colectomy. However, current methods are more costly and require highly skilled staff. In addition, the technique for lymphadenectomy has yet to be standardized. We developed a technique that uses a nylon suture to elevate the(More)
