JOURNAL FREE ACCESSIn 1978, we began a mass screening survey for detecting colorectal cancers in early stage by testing fecal occult blood. Since April, 1982, a new program of mass screening was started. Small amount of feces smeared on guaiac impregnated filter paper (Shionogi-B) under restricted diet were submitted and tested for occult blood for 3 successive days. From April 1982 to March 1983, out of 7392 participants, 1934 people (26.2 %) were selected by (a) the fecal occult blood testing positive group (1383), (b) the questionaire positive group (245) and (c) the familial high risk group (306). And 1251 people (64.7 %) were submitted to digital rectal examination, rigid proctosigmoidoscopy, double contrast barium enema and total colonofiberscopy if necessary. Ten people (0.14 %) had colorectal cancer, of whom 5 were in early stage. One-hundred fifty-seven (2.1 %), had polyp (s) and 113 (1.5 %) had diverticular diseases. From these results, we consider this screening method is very useful for the detection of colorectal cancer in its curable stage.View full abstractDownload PDF (390K) -

JOURNAL FREE ACCESSPrimary far advanced and locally recurrent rectal cancer with involvement of the posterior bony pelvis are rarely amenable to conventional resection, including pelvic exenteration. We, have performed total pelvic exenteration combined with sacral resection which permits a complete enbloc excision of pelvic organs, recurrent tumors and the posterior bony pelvis. Six patients were submitted to this procedures. The operation time was seven to 23 hours, aueraging 12.5 hours, and the blood loss averaged 7.800ml, (1.100ml to 26.000ml). The transected level of the sacrum was S2-3 in two patients, S3-4 in one, and S4-5 in one. Four patients are living free of disease at three, six, 10, and 12 months. The other two are living with disease at 13 and 14 months. Although this report concerns a very small series, it suggsts that total pelvic exenteration combined with sacral resection is an adequate and reasonable procedure for locally for advanced primary and recurrent rectal cancer.View full abstractDownload PDF (4384K) -
Scanning Electron Microscopic Observations as to the Atypia of AdenomasT. Arai, H. Sarashina, N. Saitoh, M. Nunomura, M. Suzuki, S. Taniyama, ...1985 Volume 38 Issue 1 Pages 16-23

JOURNAL FREE ACCESSUsing SEM, we have observed fine surface structures of colon adenomas which were endoscopically or surgically removed. Several findings on the malignant potential of colon adenomas were obtained..
As the grade of atypia of the adenoma increases, the following serial changes on its surface structure are recognized:
1) disappearance of crypt, appearance of cleft and coarseness of surface,
2) decrease of goblet cells, cellular inequality in size and disruption of cellular surface,
3) shortness and gradual depletion of microvilli,
And these ultrastructural findings correlate fairly well with the light microscopic histological diagnosis and grading.
In conclusion, scanning electron microscopic observations can reveal cellular malignant changes of colon adenomas, and the possibility of a rather earlier diagnosis of large bowel carcinoma is implied.View full abstractDownload PDF (8575K) -

JOURNAL FREE ACCESSWe report a case of a "pure" squamous cell carcinoma arising in the middle rectum in a patient who presented with severe hypercalcemia. "Pure" squamous cell carcionma of the large bowel is a distinctly rare entity. There have been 51 documented cases reported in the English literature to date. We believe that this is first case found to be associated with severe hypercalcemia.
A 44-year-old man was admitted to out hospital with a four-month history of melena. The ulcerative type of tumor was detected 10 cm above the dentateline by sigmoidoscopy, and biopsy confirmed anaplastic carcinoma. Laparotomy and low anterior resection were performed, and no distant metatases were seen at that time.
Four months after operation, he complained of feverishness and palpitation. Liver metastses and elevation of 'the serum calcium level (max. 9.6 mEq/I) were detected. Only mithramycin was effective against hypercalcemia. He died of chronic DIC nine months after operation.
Autopsy was performed, and histologic examination of the hepatic metastases revealed poorly differentiated squamous cell carcinoma with typical epithelial pearls and keratinzation. No mucin secretion was found. Parathyroid glands were normal, and only small bone metastasis of the sternum was seen. The surgical specimen was also examined. Tumor invasion extended beyond the bowel . wall, and metastases to the regional lymph nodes were found (Duke's stage .C).
Previous reported cases are reviewed, and pathogenesis of squamous cell carcinoma of the large bowel and hypercalcemia'are discussed.View full abstractDownload PDF (1450K) -

JOURNAL FREE ACCESSIn Europe and America, a certain number of cases of ileitis after total colectomy have been reported ; however, no reports have been made in Japan.
We recognized ileitis after total colectomy in 2 cases. Case 1. A 29-year-old male. In 1968, he was diagnosed as having ulcerative colitis. A total proctocolectomy was done in 1972. In 1973, diarrhea appeared and he was given an ileostomy. In 1980, he hemorrhaged from the distal part of the ileum and was diagnosed as having ileitis.
Case 2. A 31-year-old female. She received a total colectomy and ileorectal anastomosis in 1970, on a diagnosis of ulcerative colitis. One year after the operation, diarrhea started, and she was diagnosed by colonoscopy as having ileitis. After conservative observational therapy, she died of peritonitis due to perforation of the ileum at another hospital in 1980.View full abstractDownload PDF (3671K) -

JOURNAL FREE ACCESSArteriovenous malformation of the colon causing gastrointestinal bleeding is considered to be very rare because routine barium contrast studies and endoscopy fail to demonstrate the lesion. In the Japanese literature, only 11 cases, including the present one, have been reported. Meyer identified 218 patients with arteriographically documented arteriovenous malformations, including his own 22 cases. Recently, we experienced a case of arteriovenous malformation of the right colon causing gastrointestinal bleeding and obtained specific findings arteriographically. The patient was operated on successfully.View full abstractDownload PDF (3541K) -

JOURNAL FREE ACCESSIn general, nonspecific ulcer of the rectum is very rare. A 59-year-old female developed rectal bleeding during hospitalization for heart disease. Barium enema study and sigmoi-dscopy revealed an oval ulcer at the right side of the rectal wall with white plaque, hemorrhage and mild fold convergency. Biopsy specimens were negative for malignant cells, and diagnosis of nonspecific rectal ulcer was made.
After one and half a month, the ulcer was almost healed with fold convergency and elevation of the floor. After a year, the ulcer turned to a cicatrix, endoscopically showing a small elevation at the center and a linear cicatrical change distal to it.
This case is compatible with the so-called acute hemorrhagic rectal ulcer, which has been discussed as a new concept in recent literature.View full abstractDownload PDF (2835K) -

JOURNAL FREE ACCESSTwenty-eight patients with colorectal cancer were evaluaed for postoperative wound infections. Thirteen (group I) recieved preoperative prophylactic parenteral administration of cefotaxime and 15 (group II) other antibiotics only postoperatively. No wound infections occured in group I, but three infectious complications were seen in group II (two wound ab-scesses and one wound dehiscence).
Serial monitoring of cefotaxime concentration in the blood and tissue confirmed that effective drug concentrations were achieved in the tissue of the operative wound during the operation. It was concluded that the preoperative parenteral administration of antibiotics is an essential part of the prophylaxis for infectious complications in patients undergoing colorec-tal surgery.View full abstractDownload PDF (242K) -
