The incidence of four plain abdominal film features associated with intussusception was recorded by four observers in 180 films of patients with intussusception mixed with 100 films of control subjects. The crescent sign and target sign were the most accurate indicators of intussusception. The target sign was the commoner being seen in 68% of films. Signs of small bowel obstruction were not useful in the diagnosis of intussusception. The soft tissue mass was the commonest indicator of intussusception. The soft tissue mass was found more commonly, however, than small bowel obstruction in the control subjects who did not have intussusception.

2 patients with unusual presentations of malignant melanoma involving the small intestine, a 75-year-old woman and a 78-year-old man, are described. One underwent laparotomy for diagnosis and removal of a retroperitoneal mass, with no preoperative evidence of the primary disease. The other underwent emergency laparotomy for small bowel obstruction due to intussusception, which was found to result from a metastatic melanoma. A melanoma had been completely resected from the patient's thigh a month previously, but full investigation before the operation for intussusception failed to establish the diagnosis. Malignant melanoma tends to spread to the small intestine, but tumors of this organ are very rare. Preoperative diagnosis is important since it may improve the outcome of surgical intervention, as well as the prognosis in general.

Inflammatory fibroid polyps (IFPs) are uncommon lesions of the gastrointestinal tract. Only scattered case reports have appeared in the radiology literature. The authors reviewed the cases of 33 patients (20 women and 13 men; average age, 45 years) to determine if these polyps had any distinctive diagnostic radiologic features. The IFPs were located in the stomach (n = 16), small bowel (n = 13), and colon (n = 4). The lesions originated in the submucosa and were composed of fibroblasts, inflammatory cells, and a network of blood vessels. Gastric IFPs were most often located in the antrum and were usually ulcerated. Most of the patients presented with clinical evidence of gastrointestinal blood loss. Small bowel polyps were usually located in the ileum, and patients were typically older women with intestinal obstruction due to intussusception. Most of the lesions appeared as large, intramural masses at radiologic examination. Some of the lesions were pedunculated, and all were solitary. There were no distinctive features to differentiate IFPs from other mural or intraluminal lesions of the gastrointestinal tract.

Primary neoplasms of the small bowel are unusual and constitute 1-5% of all gastrointestinal tract neoplasms. Preoperative diagnostic difficulties, frequent dissemination at the time of the diagnosis, and poor prognosis are characteristic of this pathology. During a period of 26 years we treated 61 patients with tumors of the small bowel, 44 malignant and 18 benign (1 patient had both). The most common symptoms were abdominal pain (62%), weight loss (41%), and gastro-intestinal bleeding (31%). More than half of the patients were treated as emergencies and among the remaining, the most useful diagnostic test was the small intestinal barium study. Seventeen patients were operated on for intestinal obstruction, 6 of them due to intussusception of the tumor, while 8 other patients presented with perforation and 7 with massive gastrointestinal bleeding. Leiomyoma was the most frequent benign lesion. Among malignancies lymphoma was encountered in 38.6%, followed by adenocarcinoma (29.6%) and leiomyosarcoma (22.8%). Lymphoma was predominant among Sephardic Jews. Curative procedures were attempted in all but one of the benign cases and in 21 of the malignant cases. At the time of surgery metastases were present in 23 patients. The postoperative mortality was high (20% and 14% in the benign and malignant groups, respectively) most probably due to the high incidence of emergency surgery in a high risk population. The prognosis of the malignant tumors was poor with a 5-year survival of 18%. Their disappointing course seems to be related to late diagnosis because of nonspecific symptoms and difficulty in bringing the tumor to the fore. Hopefully, a greater awareness will lead to an earlier diagnosis and improve the prognosis.

Meckel's diverticulum is the most common congenital abnormality of the small bowel; it occurs in approximately 2% of the population. Complications of Meckel's diverticulum include hemorrhage, usually associated with heterotopic tissue within the diverticulum, intussusception, development of benign or malignant neoplasms, and inflammation. Formation of one or more enteroliths within a diverticulum is rare. An extremely rare complication is mechanical small bowel obstruction secondary to extrusion of an enterolith from a Meckel's diverticulum (Meckel's stone ileus). A case of Meckel's stone ileus is described herein, with a review of the literature of this extremely rare complication.

Enteric intussusception developed in a 43-year-old man 13 days after operation for mechanical intestinal obstruction. No leading point of the invagination was found. The case may thus be classified as idiopathic intussusception occurring in the postoperative period. To our knowledge this condition has not previously been described.

Patients aged 1 month to 12 years admitted with an acute abdominal surgical condition comprising 226 cases with and 206 cases without ascariasis, recorded in the operation theatre registers and in-patients clinical sheets, were studied in relation to morbidity, duration of operation and hospital stay and mortality. Annually, 7.5% of laparotomies were due to complications of ascariasis. Operations for ascariasis accounted for 10.6% of all hospital admissions for an acute abdominal emergency. Also, ascariasis accounted for 26.3% of emergency operations. All operated biliary obstruction cases were due to ascariasis. Moreover, 20.4% of all cases of ascariasis with abdominal complications required operation. The mean ages at operation were higher in Ascaris-induced than in non-Ascaris-induced intestinal obstruction (5.1 vs 3 yr), intussusception (3.5 vs 1.2 yr) and volvulus (4.8 vs 1.7 yr). The durations of operation and hospital stay were longer and case fatality rates higher in Ascaris-induced than in non-Ascaris-induced cases. The importance of this study in relation to the socio-economic benefits of controlling ascariasis is discussed.

During a 5 year period we have identified leiomyomas of the small intestine in six patients using enteroclysis. Gastrointestinal bleeding were the presenting symptoms in five and partial small bowel obstruction in one. The time interval between the onset of symptoms and radiological diagnosis ranged between 3 months and 5 years. All patients had previously been investigated by a number of endoscopic and barium radiology examinations and one had undergone a nondiagnostic laparotomy. The jejunum was the site of involvement in one patient and the ileum in five. The growth was intraluminal in two cases, extraluminal in three and bidirectional (dumb-bell) in one. Radiological appearances included round or broad-based semilunar intraluminal filling defects with encroachment of the lumen, or intussusception, displacement and/or indentation of the intestinal wall with effacement of the overlying mucosa or an ulcer crater, tenting deformity and mass effect on neighbouring loops. All six patients came to operation. Pre-operative radiological diagnosis was correct in five and suggestive in one. There was excellent correlation between the radiological appearances and morphology of the pathology specimens.

A retrospective review was performed to determine the utility of plain abdominal radiographs in evaluating children presenting to the emergency department. Clinical features, radiographic interpretation, and final diagnoses of 431 patients seen over one year were recorded. One hundred three (24%) patients had major diseases (ventriculoperitoneal shunt malfunction, foreign body ingestion, appendicitis, intussusception, bowel obstruction, necrotizing enterocolitis, toxic megacolon, blunt abdominal trauma, pyloric stenosis, and Hirschsprung's disease), while the remaining 328 (76%) had minor diseases. Radiographs were categorized as diagnostic, suggestive, normal, incidental, or misleading, with respect to the patient's final diagnosis. No single clinical feature was able to detect all diagnostic radiographs in patients with major diseases. Limiting radiographs to patients with prior abdominal surgery, suspected foreign body ingestion, abnormal bowel sounds, abdominal distention, or peritoneal signs identified all patients with radiographs diagnostic of a major disease while eliminating 48% of studies ordered. Our results suggest that restricting abdominal roentgenograms to patients with at least one of these features will detect most diagnostic radiographs in children with acute abdominal diseases.
