Two cases of gastric volvulus in children are reported, one acute and one chronic. The diagnosis should be suspected as an unusual cause of chronic recurring upper abdominal pain or in acute gastric obstruction. The radiographic appearances of these patients are presented. Anterior gastropexy has produced good results in both the patients described.

During an 18-month period, gastric dilatation was recognized in six guinea pigs from a colony with a monthly average of 253 animals. All of the affected guinea pigs were breeders and ranged in age from 8 to 26 months. Clinical signs were tachycardia, dyspnea, cyanosis, and marked abdominal distention. Macroscopic lesions included gastric volvulus, gastric dilatation, and splenic congestion.

Cases of acute or chronic abdominal complaints in adults can be accounted for as conditions resulting from volvulus of the stomach with oesophagial hernia. In a total of 73 cases of hiatus hernias the author has observed 6 patients with a simultaneous volvulus of the stomach (8,1%) from 1967 to 1976. Pathogenesis, symptoms, surgical indication and the operative technique are discussed. By means of gastropexy, fundiplication and narrowing of the oesphageal hiatus the patients could be freed of complaints and recurrences.

Although para-oesophageal hiatal hernia is the commonest cause of gastric volvulus, other causes of gastric volvulus require emphasis and 16 cases of gastric volvulus unassociated with hiatal hernia are reported. Delayed presentation following diaphragmatic injury was common. It is recommended that a thoracolaparotomy be performed in these patients to facilitate reduction of the volvulus, and division of intrathoracic adhesions under direct vision. In the secondary type of gastric volvulus accurate diagnosis is mandatory. Failure to recognize and treat associated disease will result in recurrence of the volvulus. A rational approach to the management of gastric volvulus is proposed.

The authors report four cases of mesenteric tumour including one cavernous lymphangioma complicated by volvulus of of the small intestine and one angiofibroma, a benign solid tumour which is rarely encountered. They comment on the preoperative assessment, which is not always possible for these patients are often operated on as an emergency. Cysts are easy to remove, but solid tumours even when benign are much more difficult to remove.

Positional anomalies of the colon may be explained by an arrest in the normal development process of the distal midgut. Aberrations involving the incipient stages of rotation lead to severe malpositions, while those involving the latter stages to milder forms. The normal embryology of the distal (postarterial) segment, as well as forms of complete and partial nonrotations, are discussed and illustrated. A survey of 39 consecutive cases of rotational abnormalities of the midgut with special emphasis on the configuration of the colon is presented. There is a high incidence of associated failure of fixation resulting in mobile colons that can be demonstrated radiographically. In addition, the great majority of colonic malrotations demonstrate rotational abnormalities involving the proximal intestinal tract. Their clinical implication is related to the presence of other incidental congenital anomalies or to complications derived from faulty mesenteric fixations such as peritoneal bands, adhesions, kinking, or intestinal volvulus.

A suicidal 67-year-old woman with manic-depressive psychosis took an overdose of asprin, amitriptyline and diazepam. The initial effects were pyrexia, tachycardia, hyperpnea, metabolic acidosis, electrocardiographic changes, hypoprothrombinemia, gastritis, and pancreatitis. Four to six weeks later, she was examined because of persistent abdominal pain with mausea, anorexia anemia, and possibly a malabsorption syndrome. An exploratory laparotomy was performed. The surgeon found several previous adhesions, a small intestinal volvulus, and a nodular pancreas. This suggested previous perforation of the small bowel from enteritis, causing a "blind-loop" syndrone. The invilved section of the small bowel was resected. With appropriate treatment, the patient is well three months after operation.

Previous ultrastructural studies on various microfilariae have suggested the presence of a trilaminar membrane at the parasite cuticle. In the present report, the formation of the cuticle of Onchocerca volvulus microfilariae was studied at different developmental stages by transmission electron microscopy of samples obtained from subcutaneous nodules of untreated patients. The cuticle is formed by the layering of surface coat fibrillar components of the hypodermal cells. No plasma membrane is found at the cuticle of the microfilaria. The use of freeze-fracture replication confirmed the absence of a classic plasma membrane at the parasite cuticle. Our results suggest that immunogenic determinants of the microfilaria cellular elements are hidden from the exterior by the acellular cuticle. This may explain the lack of cellular reaction usually found around living O. volvulus microfilariae in the dermis of onchocerciasis patients.

Ileal loop urinary diversion requires long-term followup. A case of an ileal conduit volvulus with a retroperitoneal urinoma 14 years after the initial procedure is reported. A brief discussion of long and short-term complications of ileal loops is presented.

Sigmoid volvulus occurs more frequently in the younger patient than is presently thought. It is not infrequent in females. It usually presents with "colicky" abdominal pain, long-standing constipation or obstipation, and increasing distention of several days' duration. A history of similar attacks strengthens the suspicion for this diagnosis. Abdominal x-ray films will usually reveal severe colonic dilation down to a low point in the sigmoid, without gas in the rectum. The classic "horseshoe" sign is seldom seen, but when present, strengthens the diagnosis. Surgical manipulation and pregnancy may be contributing factors. Treatment should be surgical unless contraindicated by specific circumstances.
