Carcinoids of the gastrointestinal tract.

Thirteen cases of carcinoid of the GI tract during eleven years seen in our hospital are presented. Prior to surgery, the clinical diagnosis of our 9 cases of gastric carcinoid was as follows: 7 cases were diagnosed as advanced gastric cancer, one case as perforated gastric ulcer, while a minute lesion of less than 1 cm in diameter was correctly diagnosed as a carcinoid. The tumors were all larger than 2 cm in the largest diameter with the exception of a minute lesion that appeared as a submucosal tumor and was diagnosed correctly before operation. Only one case of rectal carcinoid was diagnosed as a carcinoid endoscopically. The other two were diagnosed as rectal polyp and rectal cancer respectively. The lesion arising in the cecum was diagnosed as cecum tumor. The biopsy specimens of most carcinoids revealed adenocarcinoma pre-operatively, and only two cases were diagnosed correctly as carcinoid. In our series, we were unable to detect any symptom or sign of carcinoid syndrome, even in the case with widespread liver metastasis. We have not encountered any case of carcinoid in the appendix, which lesion has been very frequently reported in the Western countries.

Haemangiomas of the gastrointestinal tract in children.

Haemangiomas of the gastrointestinal tract are unusual vascular anomalies either in children or in adults. There is a significant difficulty in their diagnosis because of this rarity. However, when they are present, haemangiomas of the gastrointestinal tract may be a source of acute or chronic blood loss and anaemia. The case histories of two children with severe gastrointestinal bleeding due to cavernous haemangioma of the duodenum and caecum are presented in this report. Progressive haemorrhage from the gastrointestinal tract was the indication for operative intervention in both children. Each child underwent complete resections of the haemangiomas and is well and symptom-free one year after the surgical treatment. The purpose of this paper is to draw attention to this uncommon benign condition which has a relatively high mortality due to the delays in diagnosis and inadequate treatment.

Sensitivity of single and double contrast barium enema in the detection of colorectal carcinoma.

The preoperative barium enema of the 188 colorectal carcinoma patients operated at the Oulu University Central Hospital (Finland) during 1977-1982 were examined retrospectively. Altogether 112 single contrast studies and 87 double contrast studies had been made on these patients. The single contrast barium enemas had resulted in a correct diagnosis of colorectal carcinoma in 93 cases (sensitivity 83%). The correct diagnosis in the double contrast studies numbered 71 (sensitivity 82%). Most of the overlooked carcinomas were located in the caecum, in the sigmoid or the rectum. Most of the errors made in the single contrast studies were due to detection errors and poor evacuation. The most common failures in double contrast enemas were detection errors and nonvisualisation of the sigmoid. The authors recommend use of the double contrast technique and suggest that the two methods of barium enema be used to complement each other. A false negative diagnosis delayed the operation of the colorectal carcinoma patients by 2.2 months (median).

[Roentgenologic observations in small bowel lymphoma (author's transl)].

A comparison of the reontgenologic pattern of 100 cases of lymphoma of the small bowel with the clinical and pathological findings revealed three basic types: 1. The primary lymphoma with malabsorption, in which the classical tumor signs of the lymphoma are accompanied by signs of sprue in the nonlymphomatous mucosa. The disease is most severe in the duodenum and jejunum and less so in the ileal mucosa. The neoplasia is most frequently located in the upper small bowel. Severe diarrhoea, weightloss and clubbing are clinical signs. Th;is pattern is seen in the socalled "Mediterranean lymphoma" or in lymphoma associated with poorly controlled gluten sprue. 2. The primary ileocaecal lymphoma, in which the associated mucosa is usually normal. 3. The secondary lymphoma of the small bowel following disseminated lymphoma, which can not be differentiated from a stage 4 primary lymphoma of the gut. Distention and separation of the bowel loops by enlarged mesenteric lymphnodes always indicates a stage 3 or stage 4 advanced lymphoma.

[Metachronous double carcinoma of the large intestine].

Seven patients developed two separate carcinomas of the colon over an average interval between the two of 8.5 years. Five of the second tumours were discovered during routine endoscopic follow-up of the first. Ten of the 14 tumours were located in the left colon. These seven cases represent an incidence of metachronous double carcinoma of the colon of 0.9% among a total of 762 patients with carcinoma of the colon seen during the same period. Two patients died of the malignancy seven and 24 months, respectively, after the operation. The others have so far remained clinically free of tumour.
