Small bowel obstruction, excluding postoperative adhesive ileus, in patients > 1 month old treated between June 1982 and May 1992 at Gunma Children's Hospital Medical Center is reviewed. There were 32 patients, 22 boys and 10 girls, whose ages ranged from 1 month to 6 years (median 9 months). Intussusception was the most frequent cause of obstruction and was seen in 17 patients (53.1%). Causative lesions were identified in five patients, and were ileal duplication cysts in four and Meckel's diverticulum in one. Incarcerated inguinal hernia and mesenteric cysts resulted in bowel obstruction in six and three patients, respectively. Other causes included mesodiverticular band, ileal volvulus without malrotation, abnormal adhesion of omentum, abnormal band, vitelline duct remnant and trapping in a mesenteric defect. As for the age distribution, there was no significant correlation between the causes of obstruction and the age of patients. Ultrasonography was useful in differential diagnosis, and this modality should therefore be used in every patient with signs of small bowel obstruction.

In the United States, four diseases account for the vast majority of cases of lower intestinal bleeding: arteriovenous malformation, diverticulosis, neoplasms, and internal hemorrhoids. In this article the authors discuss less frequent causes of gastrointestinal bleeding. "Common" less frequent causes of gastrointestinal bleeding include solitary rectal ulcer syndrome, colonic varices, mesenteric vascular insufficiency, small bowel diverticula, Meckel's diverticulum, aortoenteric fistula, vasculitis, small intestinal ulceration, endometriosis, radiation-induced injury, and intussusception. Less frequent causes of gastrointestinal bleeding that have been recently described include portal colopathy, diversion colitis, and gastrointestinal bleeding in runners.

A 3-year-old boy with a radiographic finding of an isolated invaginated Meckel's diverticulum is presented. The abnormality simulates a polypoid filling defect in the distal small bowel on barium examination. This particular manifestation of Meckel's diverticulum is very rare and has been reported only once previously. This article re-emphasizes the need to think about this possibility when a polypoid filling defect is seen in the distal small bowel. At the time laparotomy was performed, the abnormality had progressed into a triple intussusception, a rare surgical finding.

Three infants younger than 2 years presented with episodic bloody-to-tarry stool of moderate amount. Two of them were diagnosed to have Meckel's diverticulum because of a positive 99mTc pertechnetate scan. Although the third infant had two negative radionuclide scans within 3 months, Meckel's diverticulum was still suspected by exclusion studies. All three infants underwent laparoscopic surgery. At laparoscopy, a Meckel's diverticulum was identified in all. Besides, an ileoileo intussusception just proximal to the diverticulum was also found in one patient. Reduction of the intussusception and diverticulectomy were performed successfully by laparoscopic procedure. Compared with conventional laparotomy, this procedure has the advantages of direct preoperative visual confirmation of the diagnosis, less traumatic access, much shorter recovery period and perhaps fewer intraoperative and postoperative complications. And thus, laparoscopic surgery has the potential of becoming regular treatment for symptomatic Meckel's diverticulum of infants.

Over the past decade, pneumatic reduction has been increasingly accepted as the treatment of choice for pediatric intussusception. However the effectiveness of air compared with the more traditional barium reduction of intussusception continues to be a source of concern and debate. From August 1993 to November 1994, pneumatic reduction was used to treat 75 episodes in 73 patients with proven intussusception at Chang Gung Memorial Hospital, Taoyuan. Two patients underwent air reduction twice because of recurrence following an initial successful reduction. The recurrence rate was 3%. Successful reduction was achieved in 65/75 (87%) episodes. None of the patients experienced any complications following the procedure. In two of the 10 patients in whom reduction failed, one was subsequently found to have a Meckel's diverticulum and the other a duplication cyst as a leading point. This prospective study indicates that air enema is a safe and effective form of treatment for intussusception in infants and children. Pneumatic reduction should be the treatment of choice in the initial management of intussusception.

Intussusception is the invagination of one bowel segment into another. It is an emergent condition that most commonly affects infants between five and nine months of age, but it can also occur in other age groups. The etiology is usually idiopathic in infants five to nine months of age; neonates, older children and adults more commonly have lead points such as a Meckel's diverticulum or a neoplasm. Early diagnosis is essential to avoid treatment delays, which can increase morbidity and mortality. It has been reported that patients with intussusception present with abdominal pain, vomiting and bloody stools, but this classic triad is often absent. More commonly, lethargy and irritability are the presenting signs. A rectal examination, with testing for occult blood, is an important part of the evaluation and is frequently positive. Barium enema is the gold standard for diagnosis and also has therapeutic potential for reducing the intussusception. Ultrasound is an accurate, low-risk screening tool when performed and interpreted by an experienced ultrasonographer. Surgical reduction is performed if nonoperative reduction is contraindicated or unsuccessful, or if a lead point is suspected.

Intussusception secondary to an inverted Meckel's diverticulum is considered to be a rare occurrence. The pathophysiology of the disease process results in a complicated clinical picture of chronic abdominal pain, lower gastrointestinal bleeding, and recurrent obstructive symptoms that may lead to an unnecessary delay in diagnosis. A case of an inverted Meckel's diverticulum as a lead point for an ileocolic intussusception in an adult is presented. The methods of diagnosis and the salient concepts in the surgical management of intussusception are discussed. Special features regarding the pathophysiology and treatment of an inverted Meckel's diverticulum acting as an intussusception are also reviewed.

A case of Meckel's diverticulum causing intussusception in an 8-year-old boy is presented. The Meckel's diverticulum was detected by using a Tc-99m-labeled antigranulocyte monoclonal antibody MN3 (Leukoscan; Immunomedics, Morris Plains, NJ), which is under clinical evaluation for the detection of atypical appendicitis at the authors' institution. Pathologic evaluation confirmed Meckel's diverticulitis with ileal-ileal intussusception.

Omphalomesenteric duct malformations comprise a wide spectrum of anatomic structures and associated symptoms (or no symptoms). They may range from a completely patent omphalomesenteric duct at the umbilicus to a variety of lesser remnants including cysts, fibrous cords connecting the umbilicus to the distal ileum, granulation tissue at the umbilicus, umbilical hernias, and the famous diverticulum of Meckel. Symptoms may involve fecal fistulas at the umbilicus, intussusception/prolapse of ileum at the umbilicus, intestinal obstruction from a variety of causes, melena and anemia, abdominal pain and inflammation, etc. Although symptoms occur most frequently during childhood years (especially in the first 2 years of life), they may occur through adult years as well. Although these malformations are found with equal frequency among the sexes, a significantly greater incidence of symptoms is encountered in males. Although one of the very most frequent malformations to be found (Meckel's diverticulum in 2% to 3% of the population), they are one of the most unlikely to cause symptoms (also Meckel's diverticulum). An awareness of the diversity of these malformations in type and symptomotology is essential to their proper and optimal management.

When to operate immediately, when to observe, and when not to operate at all represent major challenges in the management of a child with an acute abdomen. This article is an overview of the subject from symptom to diagnosis, evaluation, and preparation for the surgical intervention. Tables provide examples of conditions requiring prompt surgical intervention and relative surgical urgency; pathologies suitable for (initial) nonsurgical management; and clinical pictures where surgical intervention is not indicated. Factors that influence the timing of operation are provided, as is the differential diagnosis between intestinal strangulation and obstruction. Brief notes highlight four important causes of acute abdomen in children acute appendicitis, malrotation with volvulus, Meckel's diverticulum, and intussusception. These as well as other intraabdominal pathologies are illustrated by means of surgical photographs. The acute abdomen is a clinical diagnosis. Other diagnostic modalities have merely supporting roles. The decision to operate is based primarily on the results of a good history and thorough physical examination(s).
