Mucus-secreting carcinoid tumor in a colonic diverticulum: report of a case.

A mucus-secreting carcinoid tumor arising in a colonic (rectosigmoid) diverticulum is presented. Carcinoid tumors in colonic diverticula have not been previously reported. The presence of mucin and argentaffin granules in the same tumor cell is illustrated. The recognition of mucus-secreting carcinoid tumors is emphasized in order to avoid overtreatment of small colonic carcinoid tumors by extensive surgical procedures.

Adenocarcinoma, Mucinous

Inverted diverticula of the gastrointestinal tract.

Inverted diverticula of the gastrointestinal tract are rare. This paper briefly presents the roentgen findings of an inverted Meckel's diverticulum and is the first reported case of the roentgen appearance of an inverted colonic diverticulum.

Diverticular fecalith in scleroderma simulating colonic neoplasm: report of a case.

This is a report of a patient with the CRST syndrome, a mild variant of scleroderma consisting of calcinosismraynaud's phenomenon, sclerodactyly, and telangiectasia. Typical changes of scleroderma were present in the extremities, esophagus, duodenum and colon. In addition, there was a polypoid filling defect in a colonic diverticulum due to a fecalith. The radiologic appearance at first resembled a colonic neoplasm, although its location within a diverticulum and its speckled appearance suggested the possibility of a fecalith. This was confirmed at colonoscopy, which disclosed numerous wide-mouthed diverticula, with inspissated fecal material projecting from several diverticula. In patients with scleroderma and polypoid filling defects in the colon, the possibility of a fecalith within a diverticulum should be considered. Where the radiologic study is inconclusive, colonoscopy may provide a definitive diagnosis.

[The development of diverticulosis and diverticulitis (author's transl)].

The cause of colonic diverticula is myostatic spasm. A low-residue diet contributes to this state as transit time through the bowel is slowed. Information gathered in 102 cases was analysed. The smooth muscle architecture of specially prepared operative specimens of diverticulosis were examined. In every case an asymmetric contracture of the smooth musculature led to the formation of gaps. Here the mucosa and muscularis mucosae can protrude through the bowel wall. The muscular spasm is responsible for incarceration of the diverticula. Inflammatory diverticulitis is compared to appendicitis.

Appendicitis

[Pathologic-anatomic aspects of the formation and complications of diverticula (author's transl)].

Diverticulosis is favored by general (erect posture), diatetic (low-roughage diet) and anatomic factors (discontinuity and particularly spiral arrangement of the musculature). A pouch of mucous membrane passes through the bowel wall in some cases, which makes comparison to the false diverticula of the so-called trabecular urinary bladder understandable. An important feature of the pathogenesis is the displaceable layer between mucosa and musculature. Diverticulosis is the basis of a disease, i.e. diverticulitis: this begins with stercoraceous pressure ulcers, and causes granulation tissue local peridiverticulitis. In peridiverticulitis, confluated inflammation sometimes involves all the sigmoid ensheathing it, with pernicious fomation of scars, i.e. perisigmoiditis. In this way, a disease of the intestinal wall becomes a disease of the intestine. The symptoms of perisigmoiditis are similar to those of carcinoma of the sigma.

[Internal aspects of diverticulosis (author's transl)].

Diverticular disease of the colon is, apart from the irritable colon syndrome, by now probably the commonest disorder of the large intestine. The incidence of the disease seems to be increasing, which might be due to fundamental dietary changes during the last 60-80 years. It has been suggested that the condition may be a dietary deficiency disorder caused by an inadequate intake of fiber in the diet. Undiagnosed diverticulosis can suddenly progress to painful diverticular disease or diverticulitis with no warning. Complications are sometimes life-threatening, and they demand immediately surgical intervention. The optimal medical and surgical management of diverticular disease and diverticulitis is not well defined as no controlled clinical trials are available.

Colitis, Ulcerative

[Early resection in diverticulitis (author's transl)].

The danger with diverticulitis is that the disease may progress to life threatening complications. The development of diverticulitis leads from local infiltration and fibrosclerosis to final perforation. Nonresected diverticulitis favors the development of diverticulosis proximal to the affected bowel. Conservative therapy seems to be of little use in avoiding the progression of recurring diverticulitis. Signs of irreversible diverticulitis are repeated attacks, signs of local peritonitis, fixed deformation of the wall and stenosis, revelaed by barium enema. One-stage resection was performed in 101 patients for uncomplicated diverticulitis. There was one death (myocardial infarction).

Diverticulitis, Colonic

Combined horizontal and longitudinal colomyotomy for diverticular disease: preliminary report.

The operation of horizontal and longitudinal colomyotomy for diverticular disease is described and satisfactory short-term results in six patients are presented. The indications and reasons for the use of this procedure are discussed. It is suggested that the operation is a satisfactory treatment, without the risks associated with division of all the circular muscle fibers, or with resection and anastomosis. The necessity for long-term high dietary fiber intake is stressed.

Medical therapy of colonic diverticular disease.

Treatment of asymptomatic diverticulosis is geared to the prevention of constipation, with vigilance for possible signs of complications. A bulky stool decreases colonic intraluminal pressures, probably lessening pain and the chance of development of new diverticula. Increased stool weight may be achieved by the addition of vegetables, fruits, and cereals (bran) to the diet. Foods with undigestible residues should be avoided. When dietary manipulations are not well tolerated, hydrophilic bulk laxatives are a useful alternative. Treatment of acute attacks consists of bowel rest and administration of intravenous fluids and antibiotics. Side effects of anticholinergics may outweigh their questionable usefulness. Nonabsorable oral sulfonamides have little or no place in the treatment of the acute attack (peridiverticulitis).

Acute Disease

Surgical management of colonic diverticulitis and complicated diverticulosis.

The aim of surgery in the management of diverticulitis and complicated diverticulosis is to remove the disease process as quickly as possible. This approach reduces the likelihood of complications and often avoids the necessity of multistage procedures. Indications for resection include failure of a first attack to subside, recurrent attacks, and free perforation with spreading peritonitis. Three-stage procedures should be reserved for extremely serious disease. Other complications requiring surgery are fistula, obstruction, and massive and uncontrolled bleeding. Massive bleeding is caused by diffuse colonic diverticulosis and is rarely associated with diverticulitis. Abdominal mass, obstruction, or recurrent episodes of slight bleeding should suggest the possibility of underlying tumor and are compelling indications for early resection.

Abscess

Dietary fiber and diverticular disease.

Can the regular consumption of bran and other fibrous foods help in preventing diseases of the colon? Indirect evidence supports the idea, although much remains to be learned. It seems probable that bulkier feces could increase the diameter of the colon and prevent sudden sharp rises in pressure that are believed to be responsible for the formation of diverticula. For most people, fiber is probably harmless and it may do some good.
