This article describes two patients with hepatic metastases from colorectal cancer in whom a reversible enteropathy developed during the administration of hepatic artery infusion chemotherapy with 5-fluoro-2-deoxyuridine (5-FUdR) via an Infusaid Series 400 pump (Infusaid Corp., Sharon, MA). Both patients had severe diarrhea and signs that suggested small bowel obstruction. Barium studies revealed a distinctive radiologic appearance of severe narrowing of the ileum associated with complete loss of normal mucosal patterns. Results of an extensive evaluation for an infectious or toxin-related enterocolitis were negative. Perfusion studies confirmed the appropriate position of the catheters and revealed no extrahepatic perfusion. Systemic shunting of the 5-FUdR through the liver or tumor bed is postulated as the primary event, with the small bowel manifesting the major toxicity.

The most common type of gastric metastases secondary to carcinoma of the breast is the one showing a linitis plastica appearance. The roentgenologic aspect when performing an upper gastrointestinal examination with barium contrast is typical and allows the differential diagnosis with the primitive linitis. The linitis plastica type of metastatic breast carcinoma results from transmural infiltration of the stomach wall with initial deposit of tumor cells in the submucosal or subserosal regions. CT provide valuable information concerning the metastatic spread.

The pouch of Douglas (cul-de-sac) represents the caudal extension of the peritoneal cavity. It is the rectovaginal pouch in the female and the rectovesical pouch in the male. The cul-de-sac is in a dependent position when either upright or supine; it is, therefore, a frequent location for seeded lesions. Abnormalities in the cul-de-sac include metastases, abscesses, and endometriosis. These lesions may be detected by multiple modalities, including barium enema, computed tomography, and ultrasound. Examples of numerous cul-de-sac lesions are presented as they appear with different imaging modalities.

Gastrointestinal and retroperitoneal sarcoma are uncommon tumours. Out of 26 cases treated over the last 6 years, there were 16 smooth muscle tumours (SMT) and 10 non Hodgkin Lymphomas (ML). 7 cases of SMT were leiomyosarcoma. The majority of the cases were found in the stomach. 8 cases presented as acute emergencies while the non acute cases had non specific complaints. Despite the use of barium studies, gastroscopy and CT scan, only 5 cases were diagnosed preoperatively. The majority underwent curative resection. ML cases had a combination of radiotherapy and chemotherapy. 2 patients with large and high grade leiomyosarcomas have died. 4 patients with ML have also died, 2 with locally advanced disease and 2 with distant metastases. We conclude that most cases are not diagnosed preoperatively due to their rarity and nonspecific clinical presentation. The important prognostic factors are size and mitotic index for SMT and stage of the disease for ML.

The CT scans in 25 patients without ileocecal pathology and 52 patients with ileocecal abnormalities were retrospectively reviewed. The ileocecal region was identified in 18/25 (72%) of patients without pathology. Thirty of 52 patients with ileocecal pathology had inflammatory disease: Crohn's (13), appendicitis (9), abscess (6), and typhlitis (2). CT was complementary to barium studies, demonstrating wall thickening, pericolonic inflammatory change, masses, fascial thickening, and fistulae. Twenty patients had malignancy: primary carcinoma (9), metastases (7), and lymphoma (4). In all patients with carcinoma a mass was identified. Pericolonic stranding represented tumor extension in 5/6 patients. Metastases were identified as extrinsic ileocecal masses in all 7 patients. Liver, mesenteric and omental metastases were present in 8/20 patients. In patients with lymphoma there was wall thickening and two had additional pericecal lymphadenopathy. In 2 patients with hypoalbuminemia, findings included: wall thickening, mesenteric, and subcutaneous edema.

The use of preoperative computed tomographic (CT) scans of the chest in carcinoma of the esophagus to associate preoperative staging with postoperative survival is controversial. Thirty-two patients who underwent esophagectomy and reconstruction were examined with respect to a variety of variables available on preoperative evaluation, including lesion width on CT scan, lesion length on CT scan, and barium esophagogram. Each variable was evaluated for its ability to predict the presence of extraesophageal spread of tumor, as determined pathologically by logistic regression analysis. Lesions greater than 3.0 cm in width by CT scan were associated with a significantly higher incidence of extraesophageal spread. Tumor location, gender, histologic grade, presence of in situ lesions, vascular invasion, eosinophilia, nodal metastases, and preoperative chemotherapy had no predictive value for survival. Duration of survival was affected by the presence of esophageal spread of disease and lesion width. These results indicate that preoperative CT scanning can predict extraesophageal spread of tumor, and this is associated with overall survival.

Serial barium and CT studies were performed for follow-up of 35 patients who had undergone transhiatal esophagectomy with gastric interposition for esophageal carcinoma. The results were compared with the clinical and pathologic findings. Thirteen patients (37%) were clinically and radiologically free of tumor recurrence after a mean observation period of 18 months. Twenty-one patients (60%) developed recurrent carcinoma within 12 months and one patient (3%) within 14 months. Thirteen patients were clinically asymptomatic when recurrence was detected radiologically. Recurrence was initially confined to the mediastinum in one-half of the patients, whereas the others already had distant metastases when recurrence first became evident. Because most of the recurrent lesions originated outside the interposed stomach, CT was more useful than barium studies in showing early recurrence. Radiologic follow-up including CT allows earlier detection of limited recurrent carcinoma after surgery and, thus, offers the possibility of appropriate additional palliative radiotherapy or chemotherapy.

A 54-year-old Japanese woman with primary adenocarcinoma of the appendix was treated. The diagnosis was established before surgery by means of barium studies and ultrasound examination. Histologically, the tumor was a mucinous cystadenocarcinoma. The patient was treated by ileocecal resection, and a 10-month follow-up has revealed neither evidence of recurrence nor of metastases. The preoperative investigations, pathologic features and surgical management in this case are briefly discussed.

The efficacy of the barium enema examination and abdominal computed tomography (CT) was investigated in 81 patients who had undergone operation for colorectal carcinoma. Recurrent disease was found in 52 patients and was divided into local (anastomotic and perianastomotic) and remote (distant and hepatic metastases) types. In 32 patients with locally recurrent carcinoma, the sensitivity of the barium enema examination was 88%; for CT it was 69%. Conversely, the barium enema examination was not useful for detecting remote metastases shown on CT, which disclosed disease at one or more sites in 47 (90%) of the 52 patients. CT best evaluated recurrences remote from the anastomosis, pelvic recurrences in patients with colostomies, and hepatic metastases. Barium enema examination and CT were therefore found to be complementary modalities.

Reports of prolonged survival in patients with recurrent colon or rectal cancer following a reoperative surgery suggest that early diagnosis of locally persistent or limited metastatic disease may save some patients. To determine which laboratory and radiologic tests were useful, a prospective comparison of all currently available modalities was begun in 1978. Sixty-six patients at high risk for recurrent large-bowel cancer were studied. At present, mean follow-up is at 4 1/2 years. Protocol studies included monthly carcinoembryonic antigen (CEA) assays for 3 years and then at 3-month intervals for 2 more years. A review of symptoms and a physical examination were performed every 4 months for 3 years and then every 6 months for 2 more years. Computerized tomograms of the abdomen, full lung tomograms, and liver/spleen scintigrams were obtained every 4 months for 3 years and then annually for 2 more years. Intravenous pyelography, barium enema, and bone scintigraphy were performed yearly for 5 years. Thirty-three recurrences were observed in 31 patients. A progressive rise in serial CEA values was the first indication of recurrence in 22 of 33 patients (67%), review of symptoms and physical examination in seven of 33 (21%), CT scan in two of 33, and bone scintigraphy and full lung tomography each in one of 33 patients. Serial CEA assays and routine visits to a physician's office were the most useful tests in this study population. Use of a simplified follow-up plan will result in the earliest detection of recurrent colon cancer.
