Intussusception: ability of fluoroscopic images obtained during air enemas to depict lead points and other abnormalities.

PURPOSE: To evaluate the ability of fluoroscopic images obtained during air enemas to depict or exclude lead points of intussusceptions and other abnormalities that require surgical treatment in the absence of intussusception. MATERIALS AND METHODS: The clinical, radiologic, surgical, and pathologic findings were reviewed in 14 patients with lead points or other lesions. RESULTS: Fluoroscopic images failed to depict a lead point in 10 patients. The air enema easily reduced intussusceptions with benign lead points in seven patients. Fluoroscopic images depicted pathologic lead points in two patients and were normal in two patients with intussusception. Fluoroscopic images failed to depict an abnormality that required surgery in the absence of intussusception in two patients. CONCLUSION: Successful reduction of an intussusception does not always rule out a lead point. Other imaging studies, the patient's condition, and laparotomy may also be necessary to diagnose and treat lead points and other lesions.

Intussusception incidence relative to rotavirus vaccine use in Honolulu.

Rotavirus vaccine was in use during the period August 1998 to October 1999. Epidemics of intussusception during this period were allegedly due to rotavirus vaccine, which prompted the vaccine to be withdrawn. Hawaii's geographic location between Asia and the mainland United States may subject it to infectious disease epidemic periods midway between occurrence in Asia and occurrence in the mainland United States. In contrast, immunization recommendations are temporally identical across all 50 states. The purpose of this study was to determine whether an epidemic of intussusception was experienced in Honolulu during the period of rotavirus vaccine use. This is a retrospective study of data obtained from inpatient and emergency department discharge diagnosis codes of intussusception for children up to 36 months of age. The incidence data were plotted by time periods to identify possible epidemic periods. The data are graphed. The arrows on the graphs indicate the period of time that rotavirus vaccine was in use. These graphs are most consistent with an increase in the cases of intussusception during the period July 2000 to December 2000, and a possible decline of intussusception during the rotavirus vaccine period. These incidence data are inconsistent with a temporal association between rotavirus vaccine and an epidemic of intussusception in Honolulu.

Intussusception in a preterm neonate; a very rare, major intestinal problem--systematic review of cases.

Intussusception is an extremely rare disorder in preterm infants and it is often misdiagnosed as necrotizing enterocolitis. We report a case of intussusception in a 30-day-old preterm infant of 26 weeks of gestational age and a birthweight of 610 g who was diagnosed via abdominal ultra sonography. A systematic review of the literature was performed and reports on 23 previous cases were found. The presence of recognizable causes of intussusception in preterms, such as Meckel's diverticulum, bowel polypus, etc. was very infrequent. Comorbidity before and after intussusception is heterogeneous and related to prematurity. The intussusception is predominantly located in the small bowel (91.6%)--ileal or jejunal. The condition is misdiagnosed as NEC and managed conservatively until clinical deterioration occurs. A definitive diagnosis is thus established during abdominal surgery, which is usually delayed an average of 9.5 days from the onset of symptoms. Our case illustrates the capability of abdominal ultrasonography to establish early diagnosis of intussusception in the premature newborn.

Intussusception of the appendix in children.

Intussusception of the appendix is uncommon and an unusual cause of ileocolic intussusception. The pediatric age group is most often affected. Appendiceal intussusception may present as primary appendiceal invagination but more commonly leads to secondary intussusception. Two cases of partial appendiceal intussusception leading to secondary intussusception are presented. Classification, symptomatology, radiographic appearance, and differential diagnosis are discussed.

Comparison of oxygen and barium reduction of ileocolic intussusception.

Reports that gas reduction of ileocolic intussusception has a better success rate than traditional barium reduction prompted us to evaluate this technique and to compare the results with our previous experience with barium. Our method of intussusception reduction uses oxygen at a flow rate of 2 l/min and with a maximum pressure of 80 mm Hg. The results of 65 consecutive patients with 69 episodes of intussusception over a 9-month period were retrospectively reviewed. For eight episodes, gas enema was not used, including six patients who had barium reduction during the introduction of the gas technique and two patients in whom no intussusception was seen during gas enema were excluded. In the remaining 61 episodes, six patients were considered to be unacceptable risks for attempted therapeutic reduction with either oxygen or barium, according to our current criteria, and had primary surgery. Enemas with oxygen were attempted in 55 cases and were successful in 40 (73%). If all 61 cases with confirmed intussusception are included, the overall success rate with oxygen was 66%. We had greater success with oxygen than with barium (73% vs 53%), although identical pressures were used and the number of severely ill patients referred for therapeutic enema (90% vs 60%) had increased. The change in the referral pattern reflects the adoption of less conservative criteria for excluding patients from having therapeutic enema. No complications have occurred to date. We have had greater success with the use of oxygen than with that of barium, and have had no complications. Therefore, at our institution, oxygen has superseded barium for the therapeutic reduction of ileocolic intussusception.

Laparoscopic-assisted resection of ileal lipoma causing ileo-ileo-colic intussusception.

Adult intussusception is rare, and the majority of cases has an underlying cause that requires surgical resection. We report a case of a 39 yr-old man with ileo-ileo-colic intussusception caused by ileal lipoma that was successfully managed by a laparoscopic-assisted surgical maneuver. Using a three-cannula technique, ileo-colic intussusception was reduced laparoscopically. Then, through a 4-cm transverse incision in the right lower quadrant abdomen, ileo-ileal intussusception was reduced manually, and a resection of the tumor-bearing ileal segment and end-to-end anastomosis was performed extracorporeally. Although the role of laparoscopy in managing intussusception is not clearly defined, laparoscopy may be an alternative approach to the surgical treatment of adult intussusception in selected cases.

US features of transient small bowel intussusception in pediatric patients.

OBJECTIVE: To describe the sonographic (US) and clinical features of spontaneously reduced small bowel intussusception, and to discuss the management options for small bowel intussusception based on US findings with clinical correlation. MATERIALS AND METHODS: During a five years of period, 34 small bowel intussusceptions were diagnosed on US in 32 infants and children. The clinical presentations and imaging findings of the patients were reviewed. RESULTS: The clinical presentations included abdominal pain or irritability (n = 25), vomiting (n = 5), diarrhea (n = 3), bloody stool (n = 1), and abdominal distension (n = 1), in combination or alone. US showed multi-layered round masses of small (mean, 1.5+/-0.3 cm) diameters and with thin (mean, 3.5+/-1 mm) outer rims along the course of the small bowel. The mean length was 1.8+/-0.5 cm and peristalsis was seen on the video records. There were no visible lead points. The vascular flow signal appeared on color Doppler images in all 21 patients examined. Spontaneous reduction was confirmed by combinations of US (n = 28), small bowel series (n = 6), CT scan (n = 3), and surgical exploration (n = 2). All patients discharged with improved condition. CONCLUSION: Typical US findings of the transient small bowel intussusception included 1) small size without wall swelling, 2) short segment, 3) preserved wall motion, and 4) absence of the lead point. Conservative management with US monitoring rather than an immediate operation is recommended for those patient with typical transient small bowel intussusceptions. Atypical US findings or clinical deterioration of the patient with persistent intussusception warrant surgical exploration.

Pediatric intussusception in a Saudi Arabian tertiary hospital.

UNLABELLED: There are various methods of diagnosing and treating pediatric intussusception. This is an indication that no single method is acceptable to all and no single method is ideal for all cases. Because of this, we reviewed the cases and management of intussusception, seen at Aseer Central Hospital over a 7-year period. MATERIALS AND METHODS: Thirty four pediatric patients admitted at Aseer Central Hospital over a 7-year period (from 1993 to 2000) at Aseer Central Hospital, Southwestern region of Saudi Arabia were reviewed. These are by no means all the cases of intussusception seen during this period. Adult cases and incomplete records of pediatric cases were not included in this series. The 34 cases that met the objectives of this paper were analyzed with regards to the age group distribution, sex, nationality, type and site of intussusception, the cause of intussusception, the method of diagnosis and the treatment given, were also reviewed. Their case files were reviewed and used for the analysis. RESULTS: The age range was 2 months to 8 years (Mean = 10.86 months). There were 21 boys and 13 girls, a male: female ratio of 1.6:1.0. All (100%) presented with vomiting, 91% with bloody stools and 82% with colicky abdominal pain. Twenty-eight patients (82.3%) had diagnostic barium enema, and 8 of these were successfully reduced. Exploratory laparotomy was performed for 26 patients and 6 of this required surgical resection. There was no mortality in this series, but one patient had a wound dehiscence which was treated conservatively. CONCLUSION: The management of pediatric intussusception depends on the presentation, the available facilities and the expertise of the treating surgeons.

[Unexplained vague abdominal complaints in adults: indication for CT in case of suspected intussusception].

In two adult patients, a 74-year-old woman and a 84-year-old man, who suffered from vague abdominal complaints, an intussusception was diagnosed by CT. Surgical resection of the affected bowel parts was successful. Intussusception is usually seen in children; in adults it is a rare condition. Adult patients mostly complain about vague abdominal pain only. Physical examination, laboratory investigations and plain abdominal X-rays often don't give any additional information. In such patients it is advised to perform CT of the abdomen at an early stage. CT may show a so-called 'target sign' which is characteristic of an intussusception. In addition it can provide information about the possible causes of the intussusception, most commonly a malignant tumour in adults. During laparotomy one should not attempt to reduce the intussusception because of the risk of tumour spill. In this clinical review, we present two adult patients with unexplained abdominal complaints due to intussusception, caused by malignancy.

Laparoscopic reduction of appendicocecal intussusception due to mucinous cystadenoma in an adult.

OBJECTIVE: Laparoscopic reduction of appendicocecal intussusception due to mucinous cystadenoma is herein described. METHODS: A 32-year-old female had intermittent abdominal pain and nonbloody diarrhea. The preoperative diagnosis was intussusception of the colon with a benign tumor by CT-scan findings. RESULTS: Laparoscopic reduction of intussusception and ileocecal resection were successfully performed. Gauze sponge sticks were used to provide compression from the distal colon. This maneuver was very effective to reduce the intussusception. CONCLUSION: Laparoscopic reduction of intussusception due to a benign tumor is feasible and safe even in adults. Mucinous cystadenoma is one of the causes of intussusception in adults and a good indication for the laparoscopic approach.

[Reevaluation of US and CT findings in adult intussusception].

Computed tomographic (CT) and ultrasonographic (US) findings of 10 adult patients with 11 intussusceptions were retrospectively analyzed. Through close scrutiny of wall structures of intussusceptums and mesenteric fat, new features of adult intussusceptions were found: 1. The returning walls were thicker than the entering walls in 10 of 11 intussusceptums. 2. The neck of the returning wall was thicker than its head in eight of nine intussusceptums. 3. Longitudinal compression of the wall and venous congestion resulting from an inside out turning of the wall structure were thought to be the cause of thickening of the returning wall. 4. Invaginated mesenteric fat tended to be located at the head (apex) in two of seven intussusceptions, making differentiation from intussusception caused by lipoma difficult. 5. The leading masses were detectable as apical soft tissue density masses in eight of 10 intussusceptions. These findings contradict those of previous reports on adult intussusceptions.

Antiperistaltic and isoperistaltic intussusception associated with abnormal motility after Roux-en-Y gastric bypass: a case report.

Antiperistaltic and recurrent intussusceptions are extremely rare in the adult. We report a patient with both. The patient developed an antiperistaltic intussusception distal to her Roux enteroenterostomy years after a Roux-en-Y gastric bypass for morbid obesity. The diagnosis was made preoperatively with gastrointestinal contrast radiography and ultrasonography. At surgery, the intussusception was reduced, and 12 inches of nonviable bowel was resected, with a functional end-to-end anastomosis. An isoperistaltic intussusception occurred in the early postoperative period just distal to the anastomosis. Manometric evaluation of the Roux limb after the second operation showed altered gastrointestinal motility, consisting of orad-propagated and aboard-propagated migrating motor complexes, minimal phase 2 activity, and lack of conversion to the fed pattern with a liquid meal. Although manometry was not performed before the development of the intussusception, our findings are consistent with the hypothesis that altered intestinal motility may contribute to the development of intussusception.

Intussusception: is floating caecum a causative factor? Analysis of 10 cases.

Ten consecutive cases of intussusceptions treated by the authors at the University of Port Harcourt Teaching Hospital (UPTH) in a five year period are analysed. The median age of occurrence was nine months; average 5.2 years; range: one month to 25 years. The male to female ratio was 2:3. Five patients had ileocaecal, two ileoileal, two colocolic and one ileocolic intussusceptions. Of the two patients with ileoileal intussusceptions one had antegrade with Meckel's diverticulum and the other retrograde with lipoma as lead-points. The two patients with colocolic intussusceptions had mesenteric and mesocolic lymph nodes hypertrophy. The remaining six patients had freely mobile caecum anchored to the posterior peritoneum by a long mesocaecum and such arrangement was believed to be the cause of the intussusceptions. In addition to intraoperative reduction in five cases and resection with end to end ileoileal anastomosis in one, each of these six patients had the caecum fixed to the posterior abdominal wall to prevent recurrence of the intussusception.

Colonic intussusceptions in children.

There is a high incidence of primary colonic intussusceptions in infants and children in Africa. The case histories of 37 patients are reviewed. Of the varieties described, the caecocolic intussusception (16 patients) presents as an intestinal upset, often mild, with symptoms of colic and vomiting. In many of these patients there is known to be an intestinal infestation with Ascaris lumbricoides. This often leads to a delay in establishing the correct diagnosis. Colocolic intussusception (13 patients) gives rise to more acute abdominal symptoms. On clinical assessment, signs of intestinal obstruction are found and there is usually an intra-abdominal mass which can be palpated in the left colon. Further confirmatory evidence of intussusception is the finding of occult blood in stools. There is an unusually high incidence of sigmoid intussusceptions in infants (8 patients). The diagnosis of this form of intussusception is often delayed owing to inadequate clinical assessment of prolapsed bowel at the anal orifice. The length of the prolapsed bowel, the curved nature of the prolapse and the possible demonstration of a sulcus between the prolapsed bowel and the anal canal wall, aid in diagnosis.

[CT findings of invaginated mesentery in adult intussusception].

The CT findings of invaginated mesentery in adult intussusception were analyzed in 12 patients (three patients with four small bowel intussusceptions and nine patients with nine large bowel intussusceptions). In all small bowel intussusceptions, the neck was located near the superior mesenteric artery and vein (SMA & SMV) and showed a medial opening, and the vessels in the neck showed a continuity to the left side of SMA & SMV. In most of the large bowel intussusceptions, the neck was located distant from SMA & SMV, and the vessels in the neck did not show continuity to SMA & SMV. The difference in CT findings between small and large bowel intussusception is attributed to the difference in mesenteric anatomy; the small bowel and its mesentery move freely in the peritoneal cavity, whereas the large bowel is partially fixed to the retroperitoneum.

A case of intussusception and lymphoid hyperplasia in a patient with AIDS.

Idiopathic intussusception in adults is rare. In tropical climates, enteric infection is causally implicated. Three cases of intussusception in AIDS patients have been reported, two of which were associated with enteric infection. We report the fourth case of ileocolonic intussusception in an AIDS patient in whom lymphoid hyperplasia of the terminal ileum was found but no infection documented. The relationship between lymphoid hyperplasia and intussusception is discussed. The previous cases of AIDS and intussusception are reviewed. Idiopathic intussusception may become more prevalent as the number of AIDS cases increases, and must be considered in the differential diagnosis of abdominal pain in AIDS patients.

[Adenovirus and intranuclear inclusions in the appendix in children with acute intussusception].

One hundred and five appendices removed at the time of surgical reduction of intussusception in children were studied by light microscopy after routine procedures to search for aetiological factors involved in intussusception. Normal pediatric appendix specimens served as controls (n = 30). Light microscopic examination showed viral inclusions in epithelial cells in 48 of 105 appendices (45%) from the cases of intussusception. No viral inclusion was observed in controls. Immunohistochemistry performed on 21 appendices from intussusception with a monoclonal antibody against adenovirus showed intranuclear positivity in all appendices with viral inclusions. Viral inclusions seen in epithelial cells of appendices from cases of intussusception are caused by virus and in particularly by adenovirus. The etiological factors involved in intussusception without viral inclusion in appendix remain unknown.

Neonatal ileoileocolic intussusception associated with ileal polyp: report of one case.

Neonatal intussusception is an uncommon disease. We report a case of neonatal ileoileocolic intussusception led by an ileal polyp in a female neonate. The patient presented with irritable crying, bilious vomiting and frank bloody stool on the 26th day of life. On physical examination, a mobile abdominal mass was palpated. Abdominal sonography demonstrated a long segment intussusception; associated with a low echogenic mass. At laparotomy, ileoileocolic intussusception led by an ileal polyp was found. Pathology confirmed the diagnosis of polyp. Because intestinal obstruction is the primary manifestation, neonatal intussusception is initially indistinguishable from obstructions due to other reasons like intestinal atresia, congenital bands, necrotizing enterocolitis or midgut volvulus. Our experience showed that although uncommon, intussusception should be considered in the differential diagnosis of intestinal obstruction during the newborn period.
