Ornithine decarboxylase (ODC), a key enzyme in mammalian polyamine biosynthesis, has been proposed to be a marker of colonic epithelial cell proliferation and risk for colorectal cancer. We investigated the basal levels of ODC activity in sigmoid and rectal mucosae, and basal and tumor promoter 12-O-tetradecanoylphorbol-13-acetate-induced levels of skin ODC activity in individuals with a person...

We investigated the basal levels of ODC activity in sigmoid and rectal mucosae, and basal and tumor promoter 12-0tetradecanoylphorbol-1 3-acetate-induced levels of skin ODC activity in individuals with a person...

Distant metastasis of a colon carcinoma in situ has not yet been reported. We experienced a case of a sigmoid colon carcinoma in situ with common hepatic lymph node metastasis. After the first operation, we diagnosed dual intramucosal adenocarcinomas of the sigmoid colon without any regional lymph node metastasis. After the second operation, a metastatic adenocarcinoma was found in the common h...

Introduction: Disseminated carcinomatosis of the bone marrow (DCBM) caused by colorectal cancer is rarely seen. DCBM is often accompanied with diffuse intravascular coagulation (DIC). Presentation Of Case: A 72-year-old male patient with a history of right nephrectomy three decades ago for referred benign disease, underwent sigmoid colon resection for cancer causing bowel obstruction. The preop...

Takotsubo cardiomyopathy (TTC) is a stress-related cardiomyopathy that is characterized by reversible left systolic dysfunction, which appears to be precipitated by sudden emotional or physical stress in the absence of myocardial infarction. Here we present a rare case that clinically presented with intermittent abdominal pain, initially impressed as non-ST elevation myocardial infarction and c...

Metastatic recurrence of colon cancer in the left supraclavicular lymph node (Virchow lymph node) is rare, and to date there are no reports on radiotherapy as treatment. We report on a case of metastatic recurrence of sigmoid colon cancer in the Virchow lymph node with severe lymph node metastases successfully treated with a combined modality therapy of systemic chemotherapy and radiotherapy. T...

INTRODUCTION Multiple primary neoplasms are relatively rare, but their incidence has increased because of aging and improvements in diagnostic imaging. PRESENTATION OF CASE A 67-year-old man presented with epigastric pain. On upper gastrointestinal endoscopy, an ulcer was seen at the gastric angle, and biopsy showed moderately differentiated adenocarcinoma (AC). Colonoscopy demonstrated a 15-...

BACKGROUND Lymph nodes (LNs) dissection around inferior mesenteric artery (IMA) with left colic artery (LCA) preservation is difficult due to the anatomical feature of IMA. The aim of this study is to evaluate the usefulness of new ports placement inserted from a suprapubic region in laparoscopic LNs dissection around IMA with LCA preservation for sigmoid colon and ractal cancer. METHODS Twen...

Introduction: A tubo-ovarian abscess reflects an inflammatory adhesion of pelvic organs including the fallopian tube and ovary forming a palpable complex, which represents the ultimate process of pelvic inflammatory disease (PID). Fistula formation between the sigmoid colon and other pelvic organs such as the bladder, uterus, and ovary is mainly caused by colorectal cancer or diverticulitis. Ho...
