Although intrabiliary metastasis of carcinoma in the liver is unusual, intraductal and/or intraepithelial spread of cancer cells along intrahepatic bile ducts is now well recognized as hepatic metastasis. However, several clinical and laboratory findings, including images, lead us to differentially diagnose from primary intrahepatic cholangiocarcinoma. We report here on a case of colonic adenoc...

A 64-year-old man who underwent sigmoid resection for Stage 4 colon cancer had a growing nodule on the left upper lobe during follow-up. Surgical resection revealed primary pulmonary adenocarcinoma. Subsequently, a new nodule appeared in the contralateral S(1)b, for which endobronchial ultrasonography with a guide sheath (EBUS-GS) was performed for diagnosis. However, histopathologic examinatio...

Situs inversus totalis (SIT) is not itself a premalignant condition, however, rare synchronous or metachronous multiple primary malignancies have been reported. Herein we present a case of synchronous transverse and sigmoid colon cancers and a case of metachronous rectosigmoid colon and gastric cancers in patients with SIT.A 66-year-old male with SIT was referred for a two-month history of hema...

When obstructive colitis becomes fulminant, it is known as 'acute necrotizing colitis'. We report a rare case of acute necrotizing colitis due to sigmoid colon cancer, in which shock status occurred within ten hours of onset. A 79-year-old female with acute abdominal pain was transported to our hospital with acute shock. Abdominal enhanced computed tomography revealed thickening of the wall of ...

We treated a 68-year-old woman for stenosis arising from colonic diverticulosis. Two years previously, she had developed diverticulitis of the sigmoid colon, received conservative treatment, and was being carefully watched at another hospital. She began to experience irregular bowel movements and thus visited our hospital. Detailed examination showed circumferential stenosis of the colon, and p...

BACKGROUND Despite the growing acceptance of laparoscopic colon surgery, an abdominal incision is needed to remove the specimen and perform an anastomosis. Recently, natural orifice specimen extraction (NOSE) and intracorporeal anastomosis have been proposed to minimize abdominal wall trauma and improve the quality of laparoscopic colon resections Objective: To evaluate the feasibility and safe...

BACKGROUND Here we report our experience in treating colon cancer in the 5 years from 200 to 2011. Our surgical clinic treated 49 patients with colorectal cancer, of whom 28 (57.14%) were men of mean age 62 years and 21 (42.86%) were women of mean age 66 years. METHODS In 15 cases, the cancer was related to the rectum (30.61%) and the remaining 34 cases (69.39%) were related to the colon. We ...

  Lipomas of the gasterointestinal Tract are relatively uncommon in clinical practice. Most cases are asymptomatic with small tumor size and do not need any special treatment but the large ones are known to cause symptoms such as abdominal pain, obstruction, intussusceptions, and bleeding. The majority (90%) of these lesions are submucosal with predominantly right sided with a slight preponder...

We report a case of early gastric cancer and early colon cancer detected by positron emission tomography (PET) cancer screening. A 64-year-old male patient with an unremarkable past history except for hypertension and cerebrovascular disease underwent 18F-FDG PET for cancer screening. Images revealed increased uptake in the gastric antrum and sigmoid colon. Both areas appeared suspicious for ne...
