JOURNAL FREE ACCESSAmong 2, 263 patients undergoing initial surgery for colorectal cancer, poorly-differentiated adenocarcinoma was found in 76 (3.6%) The clinicopathological characteristics and prognosis according to the stage of patients with poorly-differentiated adenocarcinoma were compared with those of the 1, 931 patients (85.3%) with well-and moderately-differentiated adenocarcinoma. The former tumor was more frequently found in the right side colon than the latter, and the percentage of type 3 was higher. As for tumor invasion, more advanced cases (ss or more) were more frequently observed in the poorly-differentiated adenocarcinoma group. Lymph node metastasis (75.0%), liver metastasis (17.1%), and peritoneal dissemination (15.0%) were significantly more common in the poorly-differentiated adenocarcinoma group, and tumors of stage IIIa or more were frequent. The 5-year survival rate of patients whose tumors were removed was 21.9% for poorly-differentiated adenocarcinoma and it was lower than that for other tumors (60.5%). When the prognosis was compared after curative operation, these was no significant difference in stage I+II, but survival was significantly worse for stage IIIa or more in poorly-differentiated adenocarcinoma. In conclusion, advanced disease was more common in patients with poorly-differentiated adenocarcinoma. Prognosis may be improved by early detection and by sufficient lymphadenectomy, while effective postoperative adjuvant chemotherapy is necessary for patients with progressive cancer.View full abstractDownload PDF (352K) -

JOURNAL FREE ACCESSThe clinicopathological characteristics of 12 cases with diffusely infiltrating primary colorectal carcinoma, which accounts for 1.3% of all primary colorectal carcinoma, were studied. There were four males and eight females with a mean age of 56.9 years. Two were located in the transverse colon, one in the descending colon, three in the sigmoid colon, and six in the rectum. The positive rates of serum CEA and CA 19-9 levels were 77.8% and 50.0%, respectively, and the median values of serum CEA and CA 19-9 levels were 8.3 ng/ml and 58.5 U/ml preoperatively. Four patients had moderately-differentiated adenocarcinoma, six had poorly-differentiated adenocarcinoma, and two had mutinous carcinoma. All tumors penetrated through the bowel wall into the adjacent adipose tissue. Severe lymphatic invasion was found in 11 cases.
Nodal metastases were found in all cases, and peritoneal dissemination was found in eight cases. The histological stages were stage IIIa in one case and stage IV in the other cases. After staining, the tumors were negative for estrogen receptor in all nine cases and positive for pS 2 protein in seven of nine cases (77.8%). Only one patient survived for one year, and the other patients died of peritoneal dissemination within one year.View full abstractDownload PDF (1588K) -

JOURNAL FREE ACCESSThe patient was an 80-year-old male and the initial sympton was watery feces, followed by hematochezia when the patient visited our department. The disease was diagnosed as ulcerative colitis by the colonoscopy conducted at our department. Since liver cirrhosis, hepatocellular carcinoma, gonitis and scoliosis were complications in this patient, steroid pulse therapy was employed taking adverse reactions into consideration. Hydrocortisone sodium succinate was intravenously injected at a daily dose of 1 g and, setting three days as one cycle, four cycles were tried in total. After pulse therapy, clinical symptoms were improved together with endoscopic remission. Since aged people often have various complications, treatments in consideration of general condition and adverse reactions are necessary and pulse therapy was considered to be of the treatment modalities for ulcerative colitis.View full abstractDownload PDF (2742K) -

JOURNAL FREE ACCESSLymphoid polyp is a very rare benign non-epithelial tumor, commonly involving the rectum. It is usually present as a" sessile or semipedunculated polyp covered with normal mucosa and often eludes clinical diagnosis.
Two cases of multiple lymphoid polyps of the large intestine, which could be removed and diagnosed by colonoscopic polypectomy, were reported.
Histologically, these polyps showed lymphoid follicular hyperplasia mainly in the submucosa. No atypical lymphocytes were found. Immunohistological staining did not show any monoclonality in the lymphocytes forming the protrusion. A diagnosis of benign lymphoid follicular polyps was made.View full abstractDownload PDF (3738K) -

JOURNAL FREE ACCESSIdiopathic perforation of the large intestine is not so rare; about 130 cases have been reported in Japanese literature. However, most of them are aged persons and young persons are rare.
A case of a 29-year-old female who visited our department with the chief complaint of abdominal pain was reported. The pain gradually increased in severity, so emergency laparotomy was performed. On exploration, a perforation was found in the posterior wall of the rectum and it was closed by direct sutrure with drainage. Although no other abnormalities, suggestive of inflammation or change, were found anywhere, etiology of the perforation was unknown. The postoperative course was uneventful.View full abstractDownload PDF (1374K) -

JOURNAL FREE ACCESSThe characteristic feature of colonic lipoma associated with any malignant tumor has been reported.
In this report, a case of a 68-year-old female who had colonic lipoma of the Bauhin valve (1.5×1.5×1.3cm) and duodenal cartinoid (10×10×10cm) was presented. Other examinations indicated no metastasis. These lesions were treated by means of endoscopic resection.
All of them that were recognized by histological examinations were completely resected. After 17 months, the patient has shown no sign of recurrence.
There is no reports of a case of colonic lipoma of the Bauhin valve accompanied with duodenal cartinoid.View full abstractDownload PDF (3128K) -

JOURNAL FREE ACCESSFour cases of appendiceal cancer, which were encountered from 1991 to 1995 in the Department of Surgery, Tano General Hospital, were clinically investigated. The incidence of resection of one hundred eighty-nine colorectal cancers was 2.1% in the same period. The age range of the patients was from 36 to 56, and the mean age was 49 years. Three patients were prediagnosed as having acute appendicitis and one as having caecal cancer. The three former patients were treated by additional resection after appendectomy and the latter by right hemicolectomy.
Microscopic examination of the appendixes showed one mucinous cystadenocarcinoma, two moderately-differentiated adenocarcinomas and one poorly-differentiated adenocarcinoma.
Three appendiceal cancers were recognized in two hundred seventy-seven patients who underwent appendectomy for acute appendicitis and the incidence was 1.1% in the same period. Preoperative diagnosis of early appendiceal cancer was difficult, and differential diagnosis for acute appendicitis was especially difficult. After clinical analysis, rare appendiceal cancer should be kept in mind when appendectomy is performed. If malignancy is suspected in resected appendix, careful microscopic examination should be done and if it is malignant, an additional operation for colorectal cancer should be performed.View full abstractDownload PDF (2397K) -
