The authors report five cases of volvulus of the right side of the colon, including 3 with complications, which required segmental colonic resection. They recall the diagnostic and therapeutic problems, emphasising the interest of barium enema, the necessity of early diagnosis, the high level of mortality and the treatment of choice which is right hemicolectomy.

Ischemic colitis following conservative management of sigmoid volvulus is documented in four cases. Repeat barium enema studies in these patients showed characteristic "thumbprinting", transverse ridging, and mucosal ulcerations within a segment or the entire length of the sigmoid, lasting up to 7 days after nonoperative decompression. The development, extent, and severity of the ischemic changes seem to correlate with the degree of volvulus, blockage of venous and arterial circulation in the sigmoid mesocolon, and increased intraluminal pressure.

We have encountered two patients with volvulus of the small intestine at the ileocolic anastomosis, occurring after jejunoileal bypass. This uncommon complication is generally seen many months after bypass and may be difficult to diagnose. Barium enema examination was helpful in one patient. If there are acute, severe abdominal symptoms, mechanical obstruction and early operation should be considered. Attention has been called to other intestinal syndromes with obstructive features developing after jejunoileal bypass, and these have been compared.

The results of the radiological examination of 330 children following oral administration of barium are reported. It is pointed out that if one just takes into account the undoubted organic diseases, only a few children would benefit from the examination; in our case only 9 of them (a gastric and a duodenal ulcer, a pancreas pseudocyst, 5 hiatal hernias, and a celiac disease), i.e. 3%. This is not very satisfactory from a practical point of view. This situation improves radically when one looks for diseases usually rated as questionable: small hiatal hernia (cardiotuberositary malposition), functional disturbances of the small intestine, reactive hyperplasia of the lymphoid tissue, and chronic appendicitis. Thus we were able to offer 177 children, i.e. 53% of them, an efficacious therapy. The importance of chronic appendicitis and of functional disturbances of the small intestine as a cause of abdominal pain in children is pointed out, and their radiological symptoms are discussed. Finally the not uncommon, but not very well known disease of incomplete sigmoid volvulus is described.

Fifty patients operated upon for cecal volvulus were analyzed. The ages ranged from 14 to 88 years and averaged 53 years. Eighteen were males and 32 were females. The presentation was acute, requiring urgent surgery in 41 patients; nine patients presented with chronic symptoms and were operated upon electively. In 14 patients (28%) the cecal volvulus was temporally related to another acute medical problem. The diagnosis was made radiographically in 22 patients (44%) and at operation in 28 patients (56%). Cecal volvulus was correctly diagnosed by barium enema in 20 of the 29 patients (69%) undergoing the study. Eighteen of the patients were treated by cecopexy, 14 by resection, 12 by detorsion alone, and six by tube cecostomy. Mortality was 12% (6/50) and was associated with gangrenous cecum (33%, 3/9), other systemic diseases (24%, 5/21), age over 50 years (19%, 6/31), and acute presentation (15%, 6/41). In the absence of gangrenous cecum, enterotomy was associated with subsequent wound infection in 23% (7/30), as compared to none (0/11) when enterotomy was not performed. There were no recurrences of cecal volvulus in the entire series during follow-up which extended to 17 years, averaged 5.7 years, and was complete in 96% (42/44) of survivors. When gangrenous cecum is present, resection is the treatment of choice. In the absence of gangrenous bowel, cecopexy is recommended because of a low mortality (0/18), low morbidity (3/18), low recurrence rate (0/18) and absence of need to open the unprepped bowel.

The majority of clinically significant gastrointestinal rotational anomalies involve:(1) an arrest of rotation about the superior mesenteric vessels, (2) abnormal peritoneal bands, and (3) obstruction with or without volvulus. Between 1973 and 1978, six children had chronic intermittent volvulus secondary to a nonfixed but normally-rotated intestine; this is 10% of all infants and children treated for malrotation in our hospital during the same period. Barium studies showed normal duodenojejunal configuration and a colon that was normally situated on at least one study. All were labeled as functional complainers by their pediatricians. One died of a volvulus because her complaints were appreciated too late. At laparotomy, evidence of chronic intermittent volulus secondary to nonfixation from the ligament of Treitz to the transverse colon was found in all patients. A Ladd procedure with appendectomy was performed and immediate resolution of symptoms was noted in each surviving child. Children with a story of chronic abdominal pain deserve a carefully interpreted history and radiographic examination before being labeled as chronic complainers.

The findings on the radiographs of 14 cases of ileosigmoid knot are presented and analysed. The clinical features and pathology of the condition are briefly described. The key radiological features consist of a dilated loop of pelvic colon, evidence of small intestinal obstruction and retention of faeces in an undistended proximal colon. The dilated loop usually lies in the right side of the abdomen and the limbs taper inferiorly into the right lower quadrant. Medial deviation of the distal descending colon is an inconsistant but highly specific finding. The radiographs readily permit distinction from primary volvulus of the small intestine and from non-obstructive surgical emergencies such as perforated viscus and ruptured ectopic pregnancy. The combination of radiographic findings may however be simulated by volvulus of the right colon, closed loop small intestinal obstruction and by volvulus of the pelvic colon complicated by peritonitis. The differential diagnosis is discussed and the value of sigmoidoscopy, rather than barium enema, emphasised.

Five cases presenting in late infancy and childhood with symptoms and signs referable to malrotation of the midgut are described. The condition may present with jaundice, malabsorption or the signs and symptoms of intestinal obstruction due to internal hernia or volvulus. It may also result in volvulus and gangrene of the midgut. A short root of the mesentery predisposing to this event will be seen on a barium meal and follow through examination and will warn of its impending occurrence.

Psuedo-obstruction of the colon is a potentially lethal condition. The diagnosis should be suspected in a patient with derangement of a major extra-abdominal organ system in whom abdominal distention develops. Diagnosis is established by plain abdominal roentgenograms, signoidoscopy, and barium enema examination. The salient features of these examinations are as follows: (1) massive gaseous distention of the cecum and variable distances of the distal colon to a "cut-off-point"; (2) lack of fluid-filled colon; (3) normal sigmoidoscopy; and (4) barium enema examination, which rules out mechanical obstruction, volvulus, and mesenteric vascular ischemia. If the diameter of the cecum is less than 12 cm, conservative therapy is indicated but persistence of the distention or cecal diameter greater than 12 cm is an absolute indication for cecostomy. Perforation must be treated by cecostomy or colectomy depending on the amount of colon necrosis.

Volvulus of the sigmoid colon is a very uncommon cause of acute obstruction in children. Although common in adults in India, it was found to account for only 0.8 per cent of all acute obstructions in infants and children in this institution. It causes a proximal torsional obstruction of the colon with an acute onset of symptoms. The onset of volvulus is characterized by colicky pain over the left lower quadrant, vomiting, tenderness, and rigidity in te left lower quadrant. A scout film of the abdomen may be inconclusive, but a barium-enema examination is diagnostic. The number of cases reported is too small to allow conclusions about the best treatment for children who have sigmoidal volvulus.
