An unusual case of lymphoma is presented in which small bowel intussusception due to a lymphomatous nodule caused an acute abdomen, requiring small bowel resection. Four weeks later a second intussusception caused intestinal obstruction, necessitating a second laparotomy and bowel resection. The high incidence of malignant tumor in adult cases leads us to recommend primary resection without manual reduction in all but rectosigmoid and selected small bowel cases.

This article highlights some of the significant recent advances in imaging of the pediatric gastrointestinal tract that have occurred over the last decade. The current roles of the newer imaging modalities, including ultrasound, computed tomography, and magnetic resonance imaging, are discussed and illustrated. Particular emphasis is given to antenatal evaluation, suspected gastric outlet obstruction, inflammation, and other causes of the acute abdomen. Enhancements in fluoroscopic techniques are outlined, including the use of the newer contrast agents as well as air reduction of intussusception. Continued good communication between the pediatric radiologist and pediatric surgeon is vital to improve the care to children with disorders of the gastrointestinal tract.

Intussusception is one of the leading causes of bowel obstruction in early infancy and childhood. From 1984-1989, 67 patients under 2 years of age with intussusception were diagnosed and treated in our institution. There were 48 boys and 19 girls ranging in age from 2 months to 2 years with a mean of 7.4 months. Presenting symptoms and signs included abdominal pain (96%), vomiting (93%), rectal bleeding (60%) and a palpable mass (67%). Symptoms and signs were present for less than 24 hours in about 80% of cases. Most of the intussusceptions were of the ileocolic type (75%). The overall success rate of hydrostatic barium enema reduction was 49%. The highest rate of reduction by enema was among patients between 9 and 16 months of age (83%). The success rate of barium enema reduction was negligible after 24 hours of cardinal symptoms. Five children underwent surgical exploration without contrast studies because of delayed presentation and signs of an acute abdomen. A pathological lead point was found in only four cases, the commonest being Meckel's diverticulum. The average length of hospitalization was 2.57 days after barium enema reduction and 7.55 days after surgical reduction. There were no deaths. There was no case of perforation during enema reduction. Three children had recurrence within 3 months of initial presentation. The best outcome is associated with early diagnosis and barium enema reduction, or selected surgical intervention when indicated.

A case of urinary undiversion in a 19 year old man with high ileal loop, who at the age of 1 year was inadvertently cystectomized for probable acute urinary retention masquerading as acute abdomen, is reported. The ileo-ceco-colonic segment was isolated and the colon was partially detubularized. After ileocecal intussusception and stabilization to the cecal wall (Hendren), a segment of ileal patch was applied to form an Indiana type pouch. The ileal loop was free from the abdominal wall and its distal end was anastomosed to the terminal ileum of the pouch. Undiversion was completed by connecting the pouch at its dependent portion with the remnant prostatic urethra. At 4 months postoperatively the pouch functions quite satisfactorily as a low pressure and good volume reservoir that empties well without reflux. His erectile and ejaculatory function have also been maintained.

Intussusception is one of the more common causes of an acute abdomen in infancy. There is discussion about the appropriate method of treatment, and especially about the criteria for hydrostatic reduction. To evaluate the effectiveness of treatment of patients with intussusception presenting at the Paediatric Surgical Centre in Amsterdam, a retrospective study was carried out. 84 Cases were seen between 1980-1990. Three quarters of the children were operated, one-third without prior barium enema. In half the cases an attempt at hydrostatic reduction was made, and this succeeded in only 43%. Ultrasound was only rarely used diagnostically. The literature shows that the use of air to attempt reduction is more likely to be effective and less likely to cause complications than barium.

Mucocele of the appendix, a rare lesion, occurs in 0.3% of patients undergoing appendectomy. Only 46 cases of calcified mucocele have been reported. Complications reported include appendiceal intussusception, rupture resulting in acute abdomen, and infection. We report the case of a 74-year-old man with a calcified mucocele of the appendix that was discovered in the evaluation of a ureteral obstruction. During exploratory surgery, the patient was found to have a 6 x 5 cm appendiceal tumor and underwent a right ileocolectomy. Pathologic examination showed calcified mucous cystadenoma of the appendix. Calcification of a mucocele is believed to denote chronicity. Our case is the first report of ureteral obstruction secondary to calcified mucocele and the second calcified mucocele to be seen on computerized tomography. Calcified mucocele should be included in the differential diagnosis of any calcified tumor in the right lower quadrant.

Ultrasonography demonstrated intussusception in a healthy and well nourished seven-month-old infant who presented with a four-day history of vomiting and abdominal pain. Plain film showed a right-sided abdominal mass, a paucity of gas within the right lower quadrant and loops of distended small bowel. This led to ultrasonography of the gastrointestinal tract that demonstrated typical "bull's eye" pattern within the intussusception process. No barium studies were performed and confirmation was obtained at operation. Ultrasonography of the bowel may be of value when investigating children with atypical acute abdomen.

Enteric intussusception is one f the most frequent causes of acute abdomen in early childhood, with an incidence of 1.3-2/1000 children born and higher frequency from the third to the twelfth month. Primary intussusception is related to predisponsing factors such as peristalsis disorders or Peyer's patch hypertrophy induced by viral infection. Secondary intussusception is due to organic injury in the intestinal wall. The most involved sites are the terminal ileum and the ileocecum, the most frequent type is ileocolic intussusception. Many clinical forms exist, including acute enteric intussusception with its pathognomonic triad intermittent abdominal pain, emesis and rectal bleeding and the atypical form with a neurological presentation, where sopor, myosis and muscular atonicity are dominating, Intussusception can also present in a subacute or chronic form with a slow and apsecific onset. In a retrospective investigation we examined 30 cases of intussusception in children hospitalized at the Pediatric Clinic of Pisa from the 1960s up to today. Our patients (16 males and 14 females) were aged between one month and two years. Clinical presentations resulted in; typical forms (60%), atypical forms (16%), subacute forms 13%) and recurrent forms (10%). Clinical suspicion was confirmed either by the presence of blood observed during rectal exploration, which is a pathognomonic sign, or by the opaque enema which led to recovery by means of hydrostatic reduction in 40% of the cases. The remaining patients (60%) underwent surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

In 1978-1988 operations were performed on 92 children: 35 with diverticulitis, 7 with intestinal intussusception, 5 with hemorrhage from an ulcer of the diverticulum, 13 with strangulation or mechanical ileus, 2 with strangulated Littre's hernia, one with torsion of the omentum, 22 with secondary diverticulitis, and in 7 children Meckel's diverticulum was a chance finding during other operations in the cavities. Boys accounted for 60.9' (56) of cases. There were 12 children under one year of age, nine from 1 to 3 years, 17 from 3 to 5 years, 17 from 5 to 7 years, and 12 children aged from 7 to 10 years. The clinical manifestations depended on the pathological changes developing in Meckel's diverticulum. A clinical picture of acute appendicitis developed in diverticulitis, six children had a typical picture of intussusception, and one child had a picture of acute abdomen. Anemia and a stool with dark blood were encountered in hemorrhage from a diverticular ulcer. Seven out of 13 children with ileus had a pronounced clinical picture, in the remaining 5 it was unclear and resembled that of acute appendicitis. Meckel's diverticulum was suspected before the operation in 17 (9.95%) patients. The Volkovich-Dyakonov laparotomy approach was used in 64 children, a pararectal incision in 9, a transrectal incision in 15, a median incision in one patient, hernio-laparotomy was conducted in one and Shpizi's operation in 2 children. Diverticulectomy was accomplished by the oblique-transverse method in 79 children, by the wedge techniques in 5, by the purse-string method in 2 patients, and resection of the intestine with the diverticulum was conducted in 5 children.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute appendicitis is the first cause of emergency surgery in children. Actually, emergency abdominal sonography has evolved in differential diagnosis of acute appendicitis in children to differentiate it from other causes of acute abdomen as mesenteric lymphoadenitis, acute right pyelonephritis, acute diverticulitis in Meckel's diverticulum, intestinal intussusception, regional enterits, primary peritonitis, anaphylactoid purpura of Henoch-Schonlein. The aim of this study is the evaluation of the usefulness of abdominal sonography in diagnosing acute appendicitis in our current series of pediatric patients. We have operated 102 patients afflicted by appendicitis admitted to the pediatric department of Ospedale San Raffaele, Milano in a period of 5 years and operated on for appendectomy. In the last 2 years 36 patients were evaluated with abdominal sonography. This diagnostic tool showed in 34 (94.4%) a liquid effusion, sometimes thick of the right iliac fossa. In 2 patients the appendix had thickened layers, was edematous and the lumen was clearly filled with debris. Abdominal sonography has given a clear cut picture of the acute inflammatory process of the appendix. None of these patients has suffered from septic or obstructive complications. Mean duration of hospital stay was 6.35 days (3-15 days). Differential diagnosis of acute appendicitis can be extremely variable, from simple, paradigmatic situations to the most intriguing ones. This concept is well emphasized by William Silen when he says that "differential diagnosis of acute appendicits is an encyclopedic compendium of every abdominal disease that causes pain" in the 11th edition of Harrison's Principles of Internal Medicine.(ABSTRACT TRUNCATED AT 250 WORDS)
