A 5-day continuous infusion of vincristine (VCR; total dose 4 mg/m2) has been given as part of a high-dose chemoradiotherapy regimen with bone marrow transplantation. Evidence of neurotoxicity, such as weakness, paraesthesia and intestinal hypomotility, was evaluated prospectively in nine patients. Five patients had advanced neuroblastoma and four, relapsed sarcomas, and all had responded to initial conventional-dose therapy. VCR was combined with high-dose melphalan (180 mg/m2) and fractionated total-body irradiation. Plasma concentrations of VCR were measured by radioimmunoassay during and up to 24 h after the infusion. Serum and urine electrolytes and liver function tests were measured during VCR treatment and at regular intervals thereafter. VCR concentration at 1 h ranged from 1.8 to 10.9 (median 6.6) ng/ml, and a steady state was achieved by 13-30 h (median 16 h). Levels above 1 ng/ml were maintained throughout the 5-day period with a mean steady-state concentration of 1.7 ng/ml (range 1.3-2.15). After cessation of the infusion, serum concentrations fell to below 0.25 ng/ml within 24 h. Abdominal pain occurred in one patient, but neither constipation nor ileus was seen. In two patients severe muscle pain occurred in the lower limbs towards the end of the infusion. Significant electrolyte problems did not occur and, in particular, there was no evidence of inappropriate ADH secretion. Transient increases in liver enzymes were common but bilirubin was not elevated during the period of monitoring. This regimen allows a two-fold escalation in the dose of VCR to be administered, producing sustained high serum drug levels without major toxicity.

Twenty-seven patients with ileus were assessed using ultrasound and the related variables suggestive of ileus are presented. If special attention is directed to these variables when a patient complains of nausea, vomiting, colicky abdominal pain and so forth, this entity can be diagnosed early and accurately. Since the distended, air-filled loops of bowel are not so readily recognized, the combined use of X-ray and ultrasound will aid in a follow-up study during treatment as well as in the diagnosis.

A total of 624 patients with adenocarcinoma of the large bowel and operated between 1958 and 1978 were retrospectively studied. According to the period of operation, patients were divided into group A (1958 to 1968, n = 259) and group B (1969 to 1978, n = 365). Symptoms were closely related to tumour location. Blood loss and change in bowel habits were most frequent in patients with left-sided cancer, while anaemia, loss of body weight and abdominal pain turned out to be the predominant symptoms in patients with right-sided cancer. Patients with cancer of the transverse colon or splenic flexure showed a high incidence of ileus (19%). Resection of the primary tumour was possible in 86% of the cases. The overall morbidity was 48% and the postoperative mortality was 8%. Anastomotic dehiscence occurred in 4% of our patients. There was no significant difference in postoperative mortality between the two patient groups. The mortality is closely related to the Dukes stage (Dukes A 4%, Dukes D 19%). The overall crude survival was 45%, the corrected survival 57%. Patients with cancer of the descending colon or (recto)sigmoid had a higher corrected 5-year survival when compared to patients with cancers in other tumour sites (65% versus 52%, p less than 0.01). Dukes stage, ileus as primary symptom were also correlated with survival, while sex distribution, age and duration of symptoms were not.

The findings in acute portal vein thrombosis in a patient with chronic calcific pancreatitis and two episodes of pancreatic surgery are described. The diagnosis was made by ultrasound, which showed a dilated portal vein filled with low-level echoes, surrounding hepatic oedema, hypertrophy of the hepatic artery, splenomegaly, collateral vessels and ascites. This was confirmed by computed tomography. The ultrasonic differences in appearance between acute and chronic portal vein thrombosis are discussed, in the context of portal hypertension. The diagnosis of acute portal vein thrombosis should be considered in patients in the appropriate situation who suffer a sudden clinical deterioration with right upper quadrant or abdominal pain. Ultrasound is recommended as the imaging modality of first choice because of the flexibility of its scanning plane and its real time and Doppler capabilities. Computed tomography is valuable in patients with an ileus or heavy pancreatic calcification and for its ability to demonstrate patent vessels on intravenous injection of contrast medium.

Uncomplicated diverticular disease is usually asymptomatic. When abdominal pain or discomfort related to defecation, altered bowel habit, and flatulence occur, they are likely a result of a coexistent irritable bowel. Nonetheless, diverticula are subject to serious complications. Diverticular hemorrhage may be massive and require emergency angiography and segmental resection. Peridiverticulitis occurs when a diverticulum ruptures, perhaps because of inspissated fecal material. This occurs usually in the sigmoid, resulting in a peridiverticular abscess localized by the adjacent fat and mesentery. If the infection extends beyond this, abscess, fistula, or free perforation may occur. These complications require antibiotics, intravenous therapy, and, in the case of uncontrollable abscess or perforation, urgent surgery. Obstruction of the colon, sometimes associated with ileus, may occur and in this case one may find a carcinoma among extensive diverticular disease. Although there is insufficient evidence to justify a high-fiber diet for the general population, the notion of a low-residue diet in the management of uncomplicated diverticular disease should be laid to rest.

The diagnostic features and operative results of six patients with spontaneous aorto-caval fistula associated with abdominal aortic aneurysm were analyzed. Abdominal pain, pulsatile abdominal mass and haematuria were constant preoperative findings in all patients. Radiological signs of congestive heart failure of various degrees were present in five, abdominal bruit in four and preoperative renal failure in three patients. As preoperative diagnostic examinations i.v. pyelography was done in two patients and ultrasound scanning and angiography of the abdominal aorta in a further two patients. In one ultrasound scanning a dilated inferior vena cava and hepatic veins were seen as an indirect sign of ACF, while in both angiograms the ACF was seen. In these two cases the diagnosis of ACF was made preoperatively, while in four other cases the diagnosis was made during the operation. Three patients survived the operation and were still alive after eight months, four years and six years respectively. Postoperative complications developed in two patients: postoperative ileus in one and deep venous thrombosis and pneumonia in another. Because of its rarity aorto-caval fistula is difficult to diagnose. The presence of haematuria in a patient suffering from abdominal aortic aneurysm should strongly suggest the diagnosis of an aorto-caval fistula.

Three girls and 4 boys with the final diagnosis of ruptured appendicitis underwent 19 sonographic studies, 5 before any therapy was instituted and 14 follow-up studies. Four abscesses identified before treatment and 2 seen postoperatively were ovoid, irregularly marginated, and contained low-amplitude echoes. Gastrointestinal ileus with gas-and fluid-filled loops of bowel made the studies technically difficult. Follow-up studies also showed fluid collections distant from the original abscesses. The complete resolution of the abscess was followed sonographically in 1 patient treated with antibiotics. Ultrasound can be useful in confirming or suggesting the diagnosis of ruptured appendicitis in the child with abdominal pain, but careful attention to detail is necessary in these technically difficult studies.

The patient with acquired immune deficiency syndrome (AIDS) and abdominal pain presents the surgeon with a difficult challenge. The pain may be due to an opportunistic infection, ileus, organomegaly, or a true surgical emergency. The hospital records of 235 patients with AIDS were reviewed. Of the 29 patients with abdominal pain, 12 had infectious diarrhea, eight were diagnosed as having ileus or organomegaly, and nine had miscellaneous causes for their pain. Only five patients underwent laparotomy. Two patients were operated on for pain associated with bleeding (Meckel's diverticulum and intestinal Kaposi's sarcoma); one had a perforated duodenal ulcer and one had severe ileitis. One patient was electively operated on for Burkitt's lymphoma. Laparotomy for abdominal pain is not usually necessary in patients with AIDS. Specific recommendations for evaluation and management of these patients are offered.

Three cases of vincristine-induced gastrointestinal toxicity were treated with metoclopramide. Two patients had severe abdominal pain and adynamic ileus, while the third had severe constipation and abdominal bloating. Rapid resolution of symptoms occurred in all three patients. Metoclopramide may, therefore, prove useful in the treatment of these not infrequent toxic effects of vinca alkaloids.

Endoscopic and clinical features are reported for 39 patients detected early in the course of pseudomembranous colitis. Disease was detected early by virtue of careful surveillance in patients in whom diarrhea developed. Early proctosigmoidoscopic findings in pseudomembranous colitis are illustrated. Clinical presentation includes development of fever, leukocytosis, abdominal pain, and even an ileus picture on radiography in addition to diarrhea.
