The records of 54 pediatric patients with symptomatic malrotation of the intestine seen over a 15-year period from 1978 to 1992 were reviewed. Bilious vomiting and bloody stools were the two most common clinical presentations in neonates, while bilious vomiting, recurrent abdominal pain and failure to thrive were the most common symptoms after the newborn period. Obscure symptoms, usually of appreciable duration, were common in many patients beyond infancy. Upper gastrointestinal radiologic examination is the preferred and more accurate method of diagnosing malrotation as it has greater sensitivity than barium enema study. Laparotomy showed 24 cases with midgut volvulus. The incidence of midgut volvulus in symptomatic malrotation was 42.1% in the neonatal period, and 50% beyond the neonatal period. The majority of patients were treated by Ladd's operation. Massive gangrene of the small bowel due to volvulus was noted in five neonatal cases. Three patients subsequently died of this complication. Four patients developed a bowel obstruction secondary to adhesions, which was relieved by enterolysis. This study reiterates that newborns with symptomatic malrotation require emergency laparotomy in order to prevent catastrophic massive bowel resection.

Over a four year period, from August 1987 to July 1991, thirteen cases of chronic and recurrent gastric volvulus were encountered comprising six paediatric and seven adult patients. In none of the patients was the condition clinically suspected; diagnosis being made only at meticulous upper gastro-intestinal (UGI) barium series. The paediatric patients typically presented with obstructive symptoms of projectile vomiting especially after meals and failure to thrive. The adults had variable symptoms of dyspepsia, recurrent intermittent upper abdominal discomfort or pain, occasionally accompanied by vomiting or retching mimicking many different upper abdominal conditions, such as peptic ulcer, biliary tract or pancreatic disease but with negative findings at endoscopy and abdominal ultrasound scanning. All cases were organo-axial type of gastric volvulus. Associated conditions were small sliding hiatus hernia in two adult cases; partial small bowel malrotation in two cases, high jejunal obstruction also in two cases and congenital hip dislocation in one patient. An infant had umbilical hernia, previous meconium cyst and meconium peritonitis. The condition seems not as uncommon as previously thought; the key to diagnosis being constant awareness, a high index of clinical suspicion and a carefully performed UGI barium series especially during the attack of pain.

Abdominal hernias are a common clinical problem. The main types of abdominal hernias are external or abdominal wall hernias, which involve protrusion of abdominal contents through a defect in the abdominal wall; internal hernias, which involve protrusion of viscera through the peritoneum or mesentery and into a compartment in the abdominal cavity; and diaphragmatic hernias, which involve protrusion of abdominal contents into the chest. Clinical diagnosis of abdominal hernias can be difficult. However, plain radiography, radiography performed after administration of barium, and computed tomography allow evaluation of suspected abdominal hernias and detection of those that are clinically occult. The anatomic location of the hernia, the contents, and complications such as incarceration, bowel obstruction, volvulus, and strangulation can be demonstrated with radiologic examination. Occasionally, complications such as neoplasms or inflammatory conditions can be identified in the hernial contents. With abdominal imaging modalities, a variety of abdominal hernias can be confidently diagnosed.

The definition of volvulus is an axial twist of a portion of the gastrointestinal tract along its mesentery. The involved bowel is obstructed partially or completely with a variable degree of arterial and venous occlusion. The colon is the most common site for volvulus. The splenic flexure is the least common site of colonic volvulus. We experienced a case of the volvulus of the splenic flexure. It will be the 30th case of the volvulus involving the splenic flexure in the English literature, to our knowledge. A 30-year-old woman was admitted due to abdominal pain and distention with vomiting. An emergency barium study revealed characteristic "bird beak" sign. Surgery was performed resecting the involved colon of splenic flexure. The result was excellent.

The aim of this study was to evaluate the plain abdominal radiographs of patients thought clinically to have a sigmoid volvulus. Strict diagnostic criteria based on the findings at barium enema and/or surgery were applied to establish or refute a diagnosis of sigmoid volvulus. The presenting plain abdominal radiographs were assessed for 10 radiological signs considered valuable in the diagnosis of sigmoid volvulus. Of the 17 patients with a volvulus, 88% had 6 or more signs, and in the 5 patients without a volvulus, 80% had 4 signs or less. Five signs achieved significance in differentiating between the groups. Three signs, apex of the loop under the left hemi-diaphragm, inferior convergence on the left and the left flank overlap sign, were 100% specific as well as being highly sensitive. The signs which were least specific were a distended ahaustral sigmoid loop and an air fluid ratio greater than 2:1.

In our country, acute cecal volvulus is responsible of 3.3% of mechanical large bowel obstructions. More than half of these cases have a history compatible with intermittent cecal volvulus, an usually overlooked diagnosis. The author reports two cases of intermittent cecal volvulus, treated in the last ten years. Both patients are female, aged 45 and 71 years old, with a history of 3 and 5 years of recurrent abdominal distention located in the right lower quadrant, that relieves spontaneously after the expulsion of gases or defecation. The symptomatology of the first cases was erroneously attributed to a concomitant colonic diverticulosis and the patient was subjected to a elective sigmoidectomy. The right colon and cecum was observed located in the right lower quadrant during the operation, and an appendectomy and a tube cecostomy for cecopexia were performed. The postoperative evolution was uneventful, and the patient is asymptomatic nine years later. The diagnosis in the second case was performed with a barium enema and a cecostomy for cecopexia was performed. The patient is asymptomatic two years later. The anatomical prerequisite for this condition is a lack of fusion of ascending colon to parietal peritoneum, which allows free rotation of this segment. The diagnosis must be suspected in patients with chronic and recurrent abdominal distention and must be confirmed with a barium enema. The surgical treatment consist in the fixation of the ascending colon.

Intestinal nonrotation has been recognized as a cause of obstruction in neonates and children and may be complicated by volvulus and intestinal necrosis. It is very rarely seen in the adult and may present acutely as a bowel obstruction and intestinal ischemia associated with midgut or ileocecal volvulus, or chronically as vague intermittent abdominal pain. The purpose of this communication is to reveal the pathogenesis and the surgical significance of intestinal nonrotation in adults and to review the English and German language literature since 1923 to establish the optimal therapeutic management. Between 1983 and 1992, we have managed and observed prospectively 10 adults with intestinal nonrotation. In four patients the nonrotation has been detected at emergency laparotomy owing to midgut or ileocecal volvulus. Four patients suffered from chronic symptoms of intermittent volvulus or small bowel obstruction and in two patients the nonrotation has been noted as an incidental finding at laparotomy for another condition. A survey of the literature from 1923 to 1992 revealed 40 adults with symptomatic intestinal nonrotation to which we contribute nine patients. We establish that in the acute symptomatic pattern, only emergency laparotomy can provide the correct diagnosis and decrease the risk of bowel disturbance. In the chronic situation, barium studies of the upper and lower gastrointestinal tract reveal varying degrees of midgut malrotation and confirm the nonrotation in each case. Also, in these forms the explorative laparotomy with a consequent staging of the abdominal situs is to be recommended. All reported cases at our institutions are without complaints after surgery. Adult patients with intestinal nonrotation and acute or chronic obstructive symptoms or those detected incidentally at laparotomy for other conditions should undergo a Ladd procedure because of the risk of midgut volvulus. In this operation, the nonrotation is left in place and the ascending colon is sutured at the colon descendens and sigmoideum. After this procedure the mesenteric pedicle is fixed and the risk of midgut torsion remains minimal.

Meconium ileus was noted as an early manifestation of cystic fibrosis in 60 neonates between 1972 and 1991. There were 20 girls and 40 boys. A family history of cystic fibrosis was present in six children. Twenty-five neonates had uncomplicated meconium ileus due to inspissated meconium within the terminal ileum. Thirty-five neonates presented with 56 complications of meconium ileus, including volvulus (n = 22), atresia (n = 20), perforation (n = 6), and giant cystic meconium peritonitis (n = 8). Clinical presentation included abdominal distension, bilious vomiting, and failure to pass meconium. In two recent cases, prenatal ultrasonography detected a mass with proximal bowel distension indicative of cystic meconium peritonitis. Mechanical bowel obstruction in the other neonates was diagnosed from plain abdominal radiographs and barium enema. Ten patients with uncomplicated meconium ileus were successfully treated with a diatrizoate meglumine (Gastrografin) enema. The remaining 15 patients required a laparotomy, with 9 treated by bowel resection and enterostomy and 6 recent cases managed with enterotomy and irrigation. Complicated cases were managed by bowel resection and anastomosis (n = 15) or enterostomy (n = 20). Survival at 1 year was 92% in patients with uncomplicated meconium ileus and 89% for those with complicated meconium ileus. The therapy of choice for uncomplicated meconium ileus is nonoperative Gastrografin enema, with enterotomy and irrigation reserved for enema failures. Complicated cases require exploration and, in the absence of giant cystic meconium peritonitis, are usually amenable to bowel resection and primary anastomosis.

Malrotation of the intestinal tract is a product of a well defined aberrant embryology. Because the consequences of malrotation associated with a midgut volvulus may be catastrophic, an understanding of the anatomy, diagnostic criteria, and appropriate therapy for this putative emergency illness is imperative. This report summarizes a recent 18-month experience with this diagnosis and contrasts this experience with that in the published literature. More than half (14/22) of the patients presented during the first month of life, and all had vomiting, which in most cases was bilious. The barium upper gastrointestinal series was the preferred diagnostic study, being both sensitive (18/19, 95%) and accurate (18/21, 86%). In this series two-thirds of the patients presented with volvulus (15/22, 68%) of whom five had ischemic intestine requiring resection. One of these children died of overwhelming sepsis. A Ladd procedure was the preferred treatment, which as defined by us includes evisceration and inspection of the mesenteric root, counterclockwise derotation of a midgut volvulus, lysis of Ladd's bands with straightening of the duodenum along the right abdominal gutter, inversion-ligation appendectomy, and placement of the cecum into the left lower quadrant. A high index of suspicion in the neonate with vomiting, rapid diagnosis, and appropriate operative therapy results in a predictable favorable outcome for children with intestinal malrotation.

Six children, aged upto one year, with volvulus of the stomach are reported. Vomiting and regurgitation of feeds were the main presenting symptoms. Eventration of the left hemidiaphragm was present in four cases. Barium meal confirmed the diagnosis. Five cases were operated on through an abdominal approach. Plication of the diaphragm (3 cases), colonic displacement (2) and gastrostomy (3) were resorted to. One child needed reoperation for a missed Ladd's band. There was no operative mortality.
