[Three adult intussusception cases with colorectal cancer; CT diagnosis and its characteristic findings].

We have experienced three adult intussusception cases with colorectal cancer. In all three cases CT studies were performed prior to administering a barium enema, where we could make the exact diagnosis of the lesions in both the plain and the contrast studies. In the CT studies, the intussusception lesions showed the characteristic eccentric layered pattern. It was difficult to distinguish the tumors from the edematous intestinal walls at the proceeding portion in two cases. While in one case, the proceeding portion (the tumor itself) was pointed out as the enhanced soft tissue density mass of layered pattern with the irregular margins.

[Diagnosis and surgical treatment of intussusception in children].

The article discusses the methods of diagnosis and surgical treatment of intussusception of the intestine in children according to the stages of the disease. Colonoscopy is recommended for wide use; it helps in making the precise diagnosis in an atypical clinical picture of intussusception in the early periods, revealing the indications for operative treatment, and determining the volume of the intervention on basis of objective control of the degree of injury suffered by the strangulated intestine.

Ultrasonographic diagnosis of small-intestinal intussusception in three foals.

Small-intestinal intussusceptions were diagnosed in 3 foals. Cross-sectional ultrasonography through the apex of the intussusceptum revealed a target-like pattern with a thick hypoechoic rim. The thick hypoechoic rim was caused by severe edema of the entering and returning walls of the intussusceptum. At the more proximal portion of the intestines, where parietal edema was less severe, the image appeared as 2 concentric rings and an inner circular area. The outer ring and inner circular area were hypoechoic and represented the returning and the entering wall of the intussusceptum. An additional cross-sectional pattern can be described as double concentric rings, with the inner lumen represented by a central echogenic core. Longitudinal scannings of the involved intestinal section revealed a different view of the same anatomic situation, with 2 hyperechoic areas delineated by 3 stripes of hypoechoic intestine. Ultrasonography of a foal's abdomen provides a clinician with a rapid noninvasive technique that may aid in the differential that may aid in the differential diagnosis of colic. The ultrasonographic diagnosis of intussusception may improve the recognition of a surgical lesion and improve the potential for successful treatment.

Intussusception: the sonographic diagnosis and its clinical value.

During the past four years in our hospital, real-time sonographic examinations were performed prior to barium enema reductions in 48 proven intussusception cases. Four major sonographic findings were noted. First, a length of target configuration consisting of two rings of low echogenicity separated by an intermediate hyperechoic ring was seen on the cross-sectional image of the intussuscepted bowel. Second, a doughnut configuration consisting of a hypoechoic rim and a dense central echogenic core was noted on the cross section near the apex of the intussusceptum. Third, no demonstrable movement or change was observed in the target or doughnut configuration. Fourth, all of the exterior sonolucent rims of the target were thicker than 0.6 cm. Operative reductions were necessary in all 13 cases whose exterior rims were thicker than 1.6 cm. On the contrary, only 15 of the remaining 35 cases whose exterior rims were between 0.6 and 1.5 cm needed surgical management (p = 0.0033, Fisher's exact test).

Ultrasonographic demonstration of intussusception in the acute abdomen in a Zambian infant.

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.

Adult intussusception with an appendiceal mucocele diagnosed by CT and ultrasonography.

Mucocele of the appendix is rare and mainly found incidentally at surgery or autopsy. Clinically, this tumor is known to cause pseudomyxoma peritonei or intussusception in adults. We present a case of adult intussusception with a leading mass of appendiceal mucocele. Computed tomography was useful in resolving the nature of the leading mass.

Internal intussusception of the rectum: a changing perspective.

Internal intussusception of the rectum is the funnel-shaped infolding of the rectum during straining to defecate. Patients present with multiple symptoms; most commonly rectal pressure and pain in association with constipation and straining. Defecography (videofluoroscopy during defecation) is the method of choice for diagnosing this problem. Rectal mobility from the sacrum, infolding of the rectum and sphincter relaxation can be used to grade the findings on defecography (Grade I-IV). The optimal therapy for internal intussusception of the rectum is unknown because the cause of the problem is unknown. Conservative management is recommended in all but the most severely symptomatic patients.

Colo-recto-anal intussusception. Case report.

Two cases of colo-recto-anal intussusception are reported, both in old women and with a tumour at the apex of the intussusception. Primary resection of the sigmoid colon with terminal sigmoidostomy was successful in one case. Resection with anastomosis in the other case was followed by anastomotic leakage with peritonitis, requiring revisional closure of the rectum and terminal sigmoidostomy.

Nonimmune hydrops fetalis associated with intrauterine intussusception.

Intrauterine intussusception has been implicated as a potential cause of intestinal atresia but has not been associated previously with nonimmune hydrops fetalis. We report a patient with a significant family history of intussuception who had intrauterine intussusception associated with nonimmune hydrops fetalis.

Postoperative intussusception: experience with 36 cases in children.

Intestinal obstruction is a common postoperative complication and is usually related to peritoneal adhesion formation. A less well-recognized cause is postoperative intussusception (POI). Thirty-six instances of POI in children (aged 1 month to 18 years) were treated between 1970 and 1987. POI followed Nissen fundoplication in 9 patients, neuroblastoma resection in 5, small-bowel procedures in 4, inguinal herniorrhaphy in 3, pull-through procedures in 3, ureterostomy in 2, thoracic procedures in 2, ventral hernia in 1, nephrectomy in 1, hepatic resection in 1, Heller myotomy in 1, ventriculo-atrial shunt in 1, and gastrocystoplasty in 1. Initial symptoms included bilious vomiting or increased nasogastric drainage (after initial return of gut function) in 26 patients, abdominal distension in 24, irritability in 10, intermittent pain in 7, palpable abdominal mass in 2, rectal bleeding in 2, and lethargy in 1. The symptoms occurred 1 to 24 days (mean, 8 days) after the initial surgery. Plain abdominal radiographs revealed multiple air-fluid levels in 31 and an "adynamic ileus" in five patients. Barium contrast techniques could successfully reduce two ileocolic and one distal ileo-ileal lesions. The remainder necessitated operative management. Manual reduction was possible in 29 cases, and four children with diagnostic delay required bowel resection and an anastomosis for intestinal necrosis. The site of intussusception was ileo-ileal in 23 patients, jejunojejunal in 6, ileocolic in 5, and jejuno-ileal in 2. The diagnosis of POI should be considered in children with signs of bowel dysfunction in the early postoperative period. Contrast studies are of limited value, since most cases are confined to the small bowel. A high index of suspicion and prompt laparotomy will usually allow manual reduction of the lesion. Diagnostic delay may result in bowel necrosis.

Endoscopic appearance of the intussuscepted appendix and accurate preoperative diagnosis.

Intussusception of the appendix in a 25-yr-old man was diagnosed preoperatively. Only six such cases have been reported. This patient presented with episodes of recurrent severe right lower abdominal pain, each episode separated by several uneventful months. The diagnosis was made by radiological visualization of a polypoid lesion with a dimple at the top in the caput cecum, and by the endoscopic appearance of the polypoid mass. A sessile polypoid mass (about 1 cm) that looked like foreskin and glans was observed by colonoscopy. The dimple at the top, like glans, was partially reddish, and the steeply sloped surface, like foreskin turned inside out, was smooth. The area of dimple at the top became discernibly smaller and the appearance changed as air was led into cecum. Appendectomy was without untoward events, and the patient no longer experienced such episodes. Although intussusception of the appendix is rare, it should be included in the differential diagnosis of acute abdominal syndrome.

Jejunojejunal intussusception associated with a transmural adenocarcinoma in an aged cow.

After 3 days of intestinal obstruction, a proximal jejunojejunal intussusception was resected during surgery in an adult Holstein cow. A transmural adenocarcinoma was found at the proximal margin of the intussusception. The cow recovered well from surgery and produced milk and embryos to expectation. During the seventh month after surgery, the cow developed pneumonia and, therefore, was euthanatized. Disseminated abdominal and thoracic neoplasia was observed at necropsy.

[Two cases of intussusception of appendiceal mucocele: diagnostic value of preoperative ultrasonography].

Mucocele of the appendix was first described and named "Hydrops processus vermiformis" by Rokitansky in 1866. Intussusception of a appendiceal mucocele is very rare and we have been able to find only 14 previously reported cases. We present two cases with preoperative ultrasonography which is valuable for its diagnosis. Case 1: A 5-year-old male was admitted to Kahoku Hospital because of right lateral colic abdominal pain and tumor. Ba-enema examination revealed intussusception to the colon and ultrasonography showed the cystic mass of the appendix. Case 2: A 51-year-old female was admitted because of right lower abdominal pain. Ultrasonography was helpful showing the cystic tumor at the base of the appendix. Recent reports say that ultrasonography is valuable examination for its diagnosis. Also in our two cases preoperative ultrasonography was performed and gave us valid information for its qualitative diagnosis.

Computed tomography and sonography in small bowel intussusception: a case report.

A 23-yr-old patient with a small bowel intussusception as diagnosed by CT and sonography is presented herein. Sonographic features include a soft tissue mass of bowel origin composed of alternating echodense and echolucent rings. Intussusception by CT has a characteristic appearance created by the individual layers of bowel wall, mesenteric fat located on one margin of the bowel wall, and intraluminal contrast. Awareness of these findings are important as both CT and sonography have become a primary imaging modalities.

Inflammatory fibroid polyp of the jejunum causing intussusception.

A case of inflammatory fibroid polyp of the jejunum is presented. This is the seventh case of this type of polyp in the jejunum and, to the best of our knowledge, the first one producing jejunojejunal intussusception. Symptoms of the inflammatory fibroid polyp in this part of the intestine are usually those of intermittent obstruction or intussusception, as in our patient. The treatment is surgical excision of the polyp.

The management of infancy and childhood intussusception in a department of general surgery.

The experience with 24 intussusceptions observed in a Department of General Surgery has been reviewed. The delay between onset of symptoms and hospitalization was less than 24 hours in 58% of cases, from 24 to 48 hours in 28%, and more than 48 hours in 14% of children. 23 patients were submitted to barium enema. Hydrostatic reduction was obtained in 19 cases. Laparotomy was performed in 13 patients after failure of hydrostatic reduction and in 5 emergency cases while only 4 underwent resection. The controversies about the management of intussusception are discussed, based on a review of literature (6,542 cases). A safe diagnostic and therapeutic approach to the disease is proposed.
