Primary malignant tumors of the small intestine are uncommon. This infrequency and possible lack of awareness can result in a late diagnosis and a poor survival time. In a period of 34 years, only 55 patients were seen at our cancer institute. The average age of the patients was 56 years, with a male predominance ratio of 2.6:1.0. Twenty-one patients had adenocarcinomas, 19 had sarcomas and 15 had carcinoids. The most common signs and symptoms were abdominal pain and obstruction of the intestine. Preoperative diagnosis was established in 12 of these patients only by roentgenologic barium examination of the small intestine. At the time of diagnosis, 34 of the patients had metastasis to regional lymph nodes or distant organs. The median and five year survival times were one year and 19 per cent, respectively. Patients with carcinoids had better survival rates than those with adenocarcinomas or sarcomas. Palliative resection did not improve survival time. However, if other therapeutic modalities also were used, it might prove beneficial. Patients with palpable abdominal masses or intestinal bleeding, or both, had a worse prognosis than did those presenting with obstruction of the intestine because these are late presenting symptoms. Therefore, recurrent abdominal pain should increase clinical suspicion, and early diagnosis by careful examination of the small intestine with barium contrast material could improve the survival time. Finally, it seemed that these tumors had a high incidence of coexisting malignant conditions, as nine of the patients in our series had a second malignant tumor.

A patient over 40 years of age who complains of lower abdominal pain, constipation or diarrhea or both, and increased flatulence should be suspected of having diverticulosis. When pain becomes more severe and persistent, diverticulitis must be considered. Diagnosis depends on roentgen demonstration of the presence of diverticula. Sigmoidoscopy and barium enema study are essential to exclude coexisting disease but in diverticulitis may need to be postponed until severe local and systemic signs of inflammation have subsided. A number of diseases can simulate diverticulitis, and differential diagnosis may present considerable difficulty. Irritable colon syndrome and acute appendicitis may be indistinguishable clinically from diverticulitis. Differentiation from carcinoma is usually not difficult, but exclusion of coexistent carcinoma may be impossible except by resection. Ulcerative colitis is also easily distinguished except when, rarely, it coexists. Crohn's disease of the colon is less easily differentiated, especially in patients over 40, in whom the two diseases often coexist. Other colonic diseases, such as ischemic colitis, and pelvic inflammatory diseases usually show characteristic features which make them readily distinguishable from diverticulitis.

Examination of the records of 378 children with intussusception at our institution revealed that 29 cases were caused by an identifiable intestinal lesion. A Meckel's diverticulum was the causative agent in 21 children, all of whom were under 2 yr of age. A previously undiagnosed ileal lymphosarcoma produced the intussusception in six other children, all between 6 1/2 and 9 yr of age. Our experience indicates that any child over 6 yr of age with the clinical findings of colicky abdominal pain, bloody stools, and a palpable mass plus the radiographic evidence of intussusception must be considered to have ileal lymphosarcoma until proven otherwise. Hydrostatic reduction of the intussusception must be accompanied by extensive small bowel reflux of barium in order to effectively rule out a small intestinal lesion. If this is not accomplished, surgery should be planned with the suspicion that a malignancy may be present. If this suspicion is confirmed by frozen section, the operation procedure should include wide surgical excision of the lesion along with the regional lymph nodes.

Chronic vague abdominal pain is an extremely common complaint in children over 5 years, with a peak incidence in the 8 to 10 year group. In over 90 per cent of the cases no serious underlying organic disease will be discovered. Most disease states can be ruled out by a careful history, a meticulous physical examination, and a few simple laboratory tests such as urinalysis, sedimentation rate, hemoglobin, white blood count determination, and examination of a blood smear. If organic disease is present there are often clues in the history and the examination. The kidney is often the culprit--an intravenous pyelogram should be done if disease is suspected. Barium enema is the next most valuable test. Duodenal ulcers and abdominal epilepsy are rare and are over-diagnosed. If no organic cause is found, the parents must be convinced that the pain is real, and that "functional" does not mean "imaginary." This is best explained by comparing with "headache"--the headache resulting from stress and tension hurts every bit as much as the headache caused by a brain tumor or other intracranial pathology. Having convinced the patient and his parents that no serious disease exists, no further investigation should be carried out unless new signs or symptoms appear. The child must be returned to full activity immediately.

Diverticular disease comprises a spectrum of illness beginning with the irritable bowel syndrome and progressing to the life-threatening complications of diverticulitis and hemorrhage. Step-wise progression of this disease may be seen but is not invariably present; many patients with diverticulosis do not have preceding symptoms of the irritable bowel syndrome. The typical complaints of irregularity of bowel habits and abdominal pain will usually respond to the relatively new treatment modality of a high fiber diet with added wheat bran. Barium enema x-ray examination remains the primary diagnostic modality in the investigation of diverticular disease, and colonoscopy should be used only in the presence of certain specific circumstances. Surgery, aimed at the treatment of complications of this disease, has progressed to the point where one-stage extirpation of the diseased bowel is recommended.

Four renal allograft recipients with evidence of ischemic damage to the colon are presented and compared with 11 cases from 5 major series. Similarities in the patients included: deterioration of renal function, multiple immunosuppressive and antibiotic regimens, the use of cadaver renal allografts, and diagnostic and therapeutic measures requiring frequent enemas with barium and ion-exchange resins. Two of our patients underwent surgery for the removal of segments of necrotic colon after several weeks of fever and abdominal pain initially attributed to either acute rejection, viral infection, or pancreatitis. One patient had three days of melena and responded to non-operative therapy. The fourth patient developed ischemic colonic changes 10 weeks after allograft nephrectomy and was receiving no immunosuppression at the time. Broad spectrum antibiotics were used at various times in all patients. Early aggressive evaluation of gastrointestinal complaints--including barium enema, upper gastrointestinal series with small bowel follow-through, proctosigmoidoscopy or colonoscopy, and arteriography--is indicated, in view of the lethality of the complication of colonic ulceration. The clinical pictures presented emphasize the fact that recipients of renal allografts are commonly heir to many complications which may be considered rare in the normal population.

Ten cases of protracted diarrheal illness after the oral administration of lincomycin or clindamycin in standard dosages were observed in previously healthy subjects. An abrupt onset of diarrhea, crampy abdominal pain, fever, and leukocytosis was observed one to 12 days after discontinuation of the drug. Proctoscopic examination revealed erythematous friable mucosa covered with small raised, yellowish-white plaques that were sometimes confluent. Barium contrast studies of the colon demonstrated irregular shaggy mucosa, ulcerations, cobblestone appearance, and thumb printing. Rectal bipsy showed acute inflammation with pseudomembranes with focal or superficial ulcerations. All patients had a protracted course but recovered with supportive management. Follow-up barium enemas and proctoscopy were done on all patients and were normal. A history of diarrhea, fever, and mucosal changes seen on proctoscopy in a patient who has recently received one of these antibiotics should raise the possibility of colitis associated with clindamycin and lincomycin therapy.

A 1011/12-year-old boy with chronic ileocolic intussusception associated with ileocecal lymphosarcoma was decribed. The patient had abdominal pain of 3 months' duration, vomiting, and a firm mass with smooth surface in the right lower abdomen. Barium enema showed intussusception at the distal part of the ascending colon, which was irreducible by hydrostatic pressure. Barium by mouth revealed markedly distended small intestines, which were displaced to the left abdomen. The tumor was inoperable, and the boy died.

Ischemic colitis is a disease complex that presents as a continuum of mucosal and submucosal hemorrhage, late stricture formation and frank gangrene. The exact form depends upon the degree, site and duration of the vascular occlusion, the presence of collateral vessels and the intraluminal pressure in the colon. In a study group of 19 women and seven men, the majority of whom were in the seventh to eighth decades of life, most frequent symptoms were crampy abdominal pain and abdominal distention associated with bloody diarrhea. Ischemic colitis occurred with increased colonic intraluminal pressure, generalized decreased vascular flow and embolic phenomenon. The predominating predisposing causes were atherosclerosis, shock and congestive heart failure as well as leukemia. The results of barium enema studies showed a pathognomonic condition that included thumbprinting, mucosal ulcerations and sacculations. Arteriography, generally, was not helpful, and results of sigmoidoscopy were invariably negative, since the rectum seldom is involved in ischemic colitis. Conservative treatment should include intestinal rest, low molecular weight dextran and antibiotics. Early operative intervention is recommended when conservative therapy fails or signs of peritoneal irritation become evident.

Endometriosis is a common disease with 8-15% occurrence in women during their reproductive period. Involvement of the bowel wall occurs rather frequently and probably presents in 12-34% of patient with pelvic endometriosis. However, it is classically asymptomatic and difficult to find out. From 1977 to 1987, we had six patients of colorectal endometriosis with mainly bowel symptoms. Five of them were located at rectum and sigmoid colon, one at the hepatic flexure of colon. All of the cases developed constipation or diarrhea, and four of them had severe abdominal pain. Four cases developed rectal bleeding. Previous operation for pelvic endometriosis was noted in two cases. The detailed examination included digital examination, endoscopy, barium enema and CT scan. Suspected malignancy was the indication for surgery in 4 cases and one in rectal stenosis. Low diagnostic rate was due to the fact that endometrial tissue rarely infiltrates the mucosa. Therefore, pathology of biopsied specimen often reveals non-conclusive finding to prevent differential diagnosis. However bowel resection offers conclusive diagnosis and chances of cure. In our study, only one suspected endometriosis case received bilateral oophorectomy. The stenotic segment of rectum restored to normal caliber after operation.
