Aetiology of colonic perforation is reviewed and discussed. 8 cases of "spontaneous" ileo-colic perforations observed between 1975 and 1977 are presented. Two of these patients had recently undergone appendectomy, and 4 others showed a simultaneous distal carcinoma of the large bowel. Histo-pathological evaluation did not reveal the cause of intestinal perforation. Operative treatment and results are given.

A 65-year-old man was hospitalised for a subocclusive state, fever, 15 kg weight loss and left abdominal pain. The plain abdominal film revealed gas in the left hypochondrium. Barium enema showed a stenosis of the left colic angle. On evacuation, a little barium entered the gas-filled cavity. Left colectomy with splenectomy was carried out. The pathologist found histological evidence of a small carcinoma of the colon invading the hilum of the spleen. An intrasplenic cavity had been formed at the site of contact. Thus an intrasplenic gas collection was the presenting sign of a carcinoma of the colon. Two colosplenic fistulae of similar origin have been reported in the literature; neither associated with similar radiological findings.

In approximately 80 per cent of cases the gallbladder is closely applied to the superior medial aspect of the right colic flexure. This intimate anatomic relationship provides pathways for direct extension of both inflammatory and neoplastic lesions of the gallbladder to involve the adjacent colon. The resultant secondary colonic abnormalities noted in 15 patients have been analyzed and correlated with surgical-pathologic findings. In acute cholecystitis, barium enema examination shows evidence of indentation by an enlarged gallbladder, spasm and mucosal edema in the anterior hepatic flexure. Chronic cholecystitis results in involvement of the adjacent colon by fibrous adhesions and inflammatory reaction. These may further lead to the development of pseudotumors simulating primary carcinoma of the colon. Similar findings including cholecysto-colic fistulae may be the initial manifestations of carcinoma of the gallbladder. The spectrum of pathologic-roentgenographic alterations in the cholecysto-colic interface is described and illustrated. Recognition of these features is of critical importance for the correct interpretation of barium enema findings and the subsequent management of patients with gallbladder disorders.

Sixty nine patients over 75 years old who had a colectomy were retrospectively studied. The carcinoma of the colon represented the main indication for 42 cases (60.9%) and 22 patients (31.9%) were immediately operated. The influence of parameters such as age, sex, visceral defects, emergency, performance of a colostomy or associated intervention, type of colic pathology, was statistically studied. The age (p less than 0.05), emergency (p less than 0.03) and the number of defects greater than or equal to 3 (p less than 0.04) contribute to mortality. The number of defects greater than or equal to 3 (p less than 0.006) contributes to general morbidity. Only complications connected with the operation by itself significantly prolong the duration of hospitalization (p less than 0.02). The authors draw the conclusion that the age by itself is not a contra-indication for operation except in case of associated polyvisceral failure. In addition, it is required to carry out an early detection of colic lesions in elderly subjects in order to contemplate surgery before complications whose prognosis is fearsome (54.5% of death in emergency operation).

Out of 618 cases of colon cancer treated between 1976 and 1986, 25 had an unusual local invasion. They underwent radical surgery with total resection of one or more adjacent organs. This group is made of 17 female and 8 male patients, with an average age of 58 years. All the patients underwent resection of the colon with radical excision of the locally invaded organs. Only one case of postoperative death is recorded. Postoperative surgical complications were rare. This experience confirms that colic resection extended to adjacent organs invaded by the tumor gives a low risk of relapse and satisfying long term results in relatively young patients with good general conditions and without remote metastases.

A case of spontaneous peripelvic extravasation associated with ureteral stenosis caused by retroperitoneal lymph node metastasis of the ascending colon cancer is reported. A 47-year-old woman complained of colic on right costa-vertebral angle. Excretory urograms showed right peripelvic extravasation and CT-scan showed urinoma formation around right kidney. Subsequent examination of right retrograde pyelo-ureterograms showed ureteral stenosis at sacro-iliac region. Operative findings revealed ureteral stenosis caused by retroperitoneal lymph node metastasis of ascending colon cancer, which was regarded as inoperable. There are a few reports of spontaneous peripelvic extravasation caused by a malignant tumor in Japanese literature. Twenty of them are reviewed.

Between 1971 and 1986, 52 villous tumors of the rectum were surgically treated, which represents 8 p. cent of recto-colic tumors. The mean patient's age was 65 years. There were sessile tumors in 69 p. cent of the cases, pedunculated in 17 p. cent and flowing tumors in 12 p. cent. The mean tumor size was 3 cm. They were associated with a colon cancer in 15 p. cent of the cases, and a polyadenoma in 10 p. cent. They were located on the rectum from 0 to 6 cm in half of the cases. In one case, the tumor extended to the entire rectum. These tumors were treated in 37 cases by local excision and in 15 cases by wide excision. Three patients were re-operated upon for an extended excision. The malignant potential of the tumors was 30 p. cent including 10 p. cent of invasive malignancy. There were no surgical fatalities, but 6 p. cent of medical fatalities. There were 20 p. cent complications related to the surgical technique. 10 patients were lost to follow-up. In 42 villous tumors followed with a mean survival of 6.5 years, there were 12 recurrences: 9 underwent endoscopic excisions and in 3 cases a wide resection: Babcock, Duhamel, amputation. The various technique of tumor resection as well as operative indications of variable difficulty are presented. It seems, at present, that a total resection of the rectum with colo-anal anastomosis represents the best treatment for large flowing villous tumors extending almost though the entire rectum.(ABSTRACT TRUNCATED AT 250 WORDS)

Gastro-colic fistula is an uncommon complication of a benign gastric ulcer (Laufer et al., 1976). The commonest causes of a gastro-colic fistula are carcinoma of the stomach, carcinoma of the colon and previous gastric surgery for peptic ulcer disease (Allison, 1973; Cody et al., 1975) and surgery is the treatment of choice. We report a case of gastro-colic fistula due to a benign gastric ulcer, which healed spontaneously without treatment. Only one previous case of spontaneous healing of a gastro-colic fistula has been described (Rivera, 1972) and this patient subsequently had surgery to exclude an underlying malignant disease.

Intestinal involvement of endometriosis requiring treatment is 5%, but only 0.7% needs intestinal resection. The authors report two cases of colic endometriosis and illustrate problems in diagnosis and management of this disease. Usually intestinal endometriosis takes the form of asymptomatic superficial serosal implants, encountered incidentally at laparotomy for other diseases, but it can also result in obstruction and occasionally bleeding. Any premenopausal woman with episodic bowel symptoms associated with gynecologic complaints should be suspected of endometriosis of the colon. Diagnosis can be suspected by double-contrast enema examination and colonoscopy with biopsy, although neither is likely to establish the diagnosis with certainty. In fact there are no radiologic or diagnostic imaging findings that are specific for endometriosis and unequivocal diagnosis requires microscopic examination. Differential diagnosis includes primary carcinoma of the colon and other benign diseases (pelvic inflammatory disease, diverticulitis, inflammatory bowel disease, pelvic abscess, polyps, etc.). The treatment of patients with uncomplicated, but symptomatic gastrointestinal endometriosis depends on the age of the patient and her childbearing attitude. Resection of the affected bowel should be done in patient with pain, bleeding, changes in bowel habits and intestinal obstruction and it is necessary to avoid neglecting a malignant tumor. Total abdominal hysterectomy and bilateral oophorectomy is the treatment of choice in the perimenopausal and menopausal women. In symptomatic women desiring children the only resection of involved colon may be appropriate treatment. In these subjects hormonal therapy can be useful.

The authors base their observations on 3 cases of synchronous carcinoma of the large intestine and 1 case of association of cancer on polyps and synchronous colorectal carcinoma. After a short review of the etiopathogenetic and diagnostic aspects, they focus attention in particular on the various types on surgical approach which synchronous carcinoma of the large intestine offer to surgeons. The authors underline that numerous forms of surgery exist which are often complex and difficult, especially if multiple neoplasia involve separate colic segments and above all if they affect the distal rectal section. In conclusion, they affirm that the association of cancer on polyps and synchronous colorectal carcinoma is not rare and should be treated using combined endoscopic and surgical therapy. To the precise colic exeresis should be followed by endoscopic resection in the case of a scissil, villous polyps with high non-differentiated neoplastic tissue laying close on the endoscopic plane of section.
