Of 112 000 patients undergoing surgery between 1952 and 1973, 67 had a primary tumor of the small intestine. 22 patients had a benign tumor, 8 a carcinoid, 21 carcinoma and 15 sarcoma. Benign tumors were more frequent in the duodenum and ileum, carcinoids in the terminal ileum and carcinomas in the duodenum and jejunum. Sarcomas were found equally in all parts of the small intestine. The most common symptom for all types of the tumor was variable pain in the abdomen. Loss of weight occurred only in patients with carcinomas and sarcomas; heavy intestinal blood loss was most common in patients with benign tumors. Benign tumors often show invagination, while sarcomas cause occlusive ileus or perforation. All duodenal tumors show heavy intestinal bleeding but hematemesis is rare. Emergency surgery was necessary in 42% of patients with benign tumors or sarcoma and in 30% of patients with carcinoma. Five-year survival in patients with benign tumors is excellent (100%). Compared to this, five-year survival in patients with carcinoma, sarcoma or carcinoids is only 15%.

The authors analyse 62 patients suffering from carcinoma of the colon with metastases in the lungs. Six patients were operated on not only for primary tumor of the colon but also in solitary metastatic affection of the lungs. The interval during which a solitary metastasis in the lung was detected lasted 18.1 months on average. Palliative resection of the colon when distal metastases were found in the lungs was conducted in 21 patients; in 7 of these patients, metastases in the lungs were recognized before the operation while in 2 the diagnosed solitary metastasis was mistaken for carcinoma of the lung and only during operation for ileus was the tumor of the colon discovered. The postoperative mortality was 23.8%, in 17.7%, death was caused by incompetence of anastomosis sutures.

Leiomyosarcoma of the left kidney seen in a 58-year-old man is reported. On April 10, 1982, he complained of left flank pain. He visited our hospital and left solitary renal cyst was suspected. He had been treated as an outpatient, but left flank pain became exacervated. On May 18, he was admitted to our hospital. On June 7, radical nephrectomy was done under the diagnosis of left renal cell carcinoma. At operation, the tumor invased directory to the psoas muscle and abdominal wall, and could not be completely resected. Pathological diagnosis was renal cell carcinoma with sarcomatoid change. On July 1, he was discharged from the hospital. In December, left flank distention appeared and back pain became exacervated. On February 8, 1983, he was readmitted to our hospital. Low density area was found in left psoas muscle by CT scanning and recurrence of renal cell carcinoma was suspected. alpha-Interferon therapy had been done, but tumor increased remarkably and caused ileus. He died on June 14, 1983. The autopsy revealed a child head-sized cystic tumor in the upper retroperitoneal space, a 5 X 5 X 5 cm metastasis of the left lobe of the liver, a 3 X 3 X 4 cm tumor to the left upper lobe with cavity formation and direct invasion into the spleen, diaphragma and gastric serosa. These metastatic lesions were leiomyosarcoma. Retrospectively, the primary tumor of kidney revealed primary leiomyosarcoma of kidney.

Direct outcomes of 215 urgent operations for complicated forms of carcinoma of the colon were analyzed. Operations for acute ileus were performed in 147 patients, for perforation of the bowel and peritonitis in 45 patients, for profuse intestinal bleedings in 23 patients. The lethality after the urgent operations was 32.5%. Operations with the removal of the primary tumor give better direct and remote results.

A total of 232 patients with obturation ileus, caused by locally advanced colorectal carcinoma, are operated over a 12-year period (1979-1990). In 160 patients (68.97 per cent) the tumor is located in the colon, and in 72 (31.03 per cent)-in the rectum. The operative interventions performed are distributed as follows: 122 (52.58 per cent) radical, and 110 (47.42 per cent) palliative. There are 84 patients (36.03 per cent) in IV clinical stage. Postoperative lethality among those subjected to radical operation amounts to 25.41 per cent, with leading underlying causes-peritonitis (35.08 per cent) and serious ileus intoxication (21.05 per cent). The survival over 1, 3 and 5-year periods among those radically operated is 74.59, 48.37 and 34.06 per cent, respectively. Histologically differentiated adenocarcinoma is demonstrated in 69.38 per cent, undifferentiated-in 17.50 per cent, and mucinous adenocarcinoma-in 13.12 per cent. The factors with a high prognostic value include: stage of primary tumor development, lymph involvement, type of operative intervention and histological variant of the neoplasm.

Volvulus of the small intestine is a condition of bowel obstruction due to knotting and twisting of the small intestine. Two types of volvulus are described: 1) primary small intestinal volvulus where no predisposing factors exist, and 2) secondary volvulus where congenital or acquired conditions promote twisting of the small intestine. Over a 5-year period, 18 patients (eleven men and seven women) presenting volvulus of the small intestine are operated in the Emergency Surgery Clinic of the University Hospital "Queen Giovanna", representing 8.7 per cent of the total of 206 cases of small intestinal mechanical ileus (incarcerated herniations involving the small intestine are not included in the series). Primary volvulus is found in one patient. In those presenting secondary volvulus adhesions are the commonest underlying cause of small intestinal rotation--13 cases, next ranking primary tumor of the small intestine--one case, Meckel's diverticulum--one, carcinosis of peritoneum--one, and one patient with small intestine volvulation around colostomy. The most frequently encountered symptoms and laboratory examinations performed are analyzed. Intestinal necrosis is established in four instances (22 per cent). One patient dies of peritonitis and polyorganic insufficiency. Volvulus of the small intestine should be mandatorily considered in patients presenting mechanical ileus of the small intestine. Early operative intervention is a therapeutic approach contributing to preclude intestinal necrosis.

Carcinoid tumors are new growths from neuroendocrine cells. The following clinical variants of carcinoid were observed in 11 patients with histologically verified carcinoid: 1) asymptomatic variant (an occasional finding at endoscopy)--2 cases; 2) carcinoid with symptoms of a mass detected at surgery--2 cases of intestinal ileus, 2 cases of appendix carcinoid simulating acute appendicitis; 3) carcinoid with hepatic metastases and carcinoid syndrome with unknown primary focus--2 cases; 4) carcinoid with metastases to the liver and carcinoid syndrome with location of the primary tumor in the lungs (2 cases) and pancreas (1 case). It is stated that carcinoid tumors are encountered more frequently than diagnosed (0.1-0.5% of all the tumors). Manifestations of carcinoid syndrome allow to diagnose carcinoid only at late stage when a large mass of hormone-active tumor tissue and metastases to the liver are present.

The patient was a 76-year-old man having gastric cancer with peritoneal dissemination. He underwent total gastrectomy for resection of the primary tumor and improvement of the oral intake. He developed ileus and peritonitis after the surgery, which necessitated two additional operations. An intestinal stoma was thus therefore created using a catheter for tube feeding, and tube feeding was initiated after the surgery. Nutrients, as well as TS-1 (taken out of the capsule; 80 mg/day) were administered via the catheter for tube feeding. This therapy was followed by a reduction in tumor marker levels and improvement of the patient's performance status (PS), after which the patient could be discharged. He stayed at home for about 8 months, with a much-improved quality of life during this period. We concluded that the TS-1 therapy via the catheter used for alimentation was effective for the treatment of cancer in this patient. We report our experience with this case, in which tube feeding became necessary after total gastrectomy, but administration of TS-1 via the same catheter used for alimentation improved the patient's PS and made it possible for him to receive chemotherapy at home.

A 54-year-old woman was operated for obstructive ileus in 1996. Obstruction was caused by a tumor of the descending colon invading the abdominal wall. Urgent left colectomy with lymphadenectomy was performed. Microscopically six lymphatic nodes were positive. The patient was postoperatively treated with adjuvant chemotherapy. Fifteen months later the patient underwent a resection of central hepatic segments (Couinaud's segment 4,5,8) for metachronous metastasis. At present the patient has no signs of recurrence, she has returned back to her normal life. Despite several unfavorable prognostic factors--obstruction, abdominal wall infiltration, number of positive nodes, short time between primary tumor resection and diagnosis of liver metastasis and centrally located metastasis with satellite lesions, the patient has been surviving for 6 years now.

The purpose of this study is to evaluate the efficacy of intraoperative radiation therapy (IORT) and the problem of securing the IORT field in advanced pediatric neuroblastoma. Between 1996 and 2005, 12 children received IORT for advanced pediatric neuroblastoma patients. Electron beam energies ranged from 10 to 12 MeV and median dose was 10 Gy (8-12 Gy). All of them had surgery with IORT against the primary tumor site and the abdominal aorta surroundings. A gross total resection (GTR) was achieved in 10 patients and subtotal resection (STR) was two patients. All of 12 patients were classified as high risk. Nine patients were alive 17-120 (mean 48 months) after diagnosis. Local tumor control was achieved in 100% of patients, of whom one experienced local recurrence outside the IORT field. At the operation, it was difficult to secure the IORT field because of the angle of the radiation cylinder in three patients. One of the three of these patients experienced local recurrence outside of the IORT field in the upper side of superior mesenteric artery and two of three patients had an external beam radiation after surgery, and there was no local recurrence. One patient had a postoperative ileus, and one patient had transient diarrhea and hydronephrosis. For advanced neuroblastoma patients, IORT produced excellent local control after surgery. However, there is a problem of securing the IORT field. For local control, it is necessary to add an external beam radiation after IORT when it is difficult to secure the IORT field.
