Trends in childhood intussusception in a Nigerian tertiary hospital.

Background: Early presentation, high rate of successful non-operative treatment, low morbidity and mortality in childhood intussusception is common in High and Upper Middle-Income Countries but not in many Lower middle- and Low-income countries. Aim: To assess the trends in the profile, treatment modalities and outcomes of intussusception in our hospital. Materials and methods: Retrospective study over a 12-year period divided into two 6-year periods. Data entry/analysis was done using SPSS and various indices were compared between these two periods. Two-tailed t-test for two independent means was used to compare means while two-tailed Fisher exact tests were used to compare categorical variables. Results were presented as tables, means, ranges, percentages and a p-value less than 0.05 was deemed statistically significant. Results: There was a significant increase in the proportion of successful non-operative treatment (18.6% vs 34%, p=0.03), reduction in the incidence of operative manual reduction (27.1% vs 12.8%; p=0.026), reduction in operative treatment (78.5% vs 63.9%, p=0.034), increased utilization of pre-intervention ultrasound (75% vs96.7%, p<0.0001) and reduction in hospital stay duration (10.47 ±7.95days vs 7.24±4.86 days; p=0.004). Conclusions: Contribution of successful non-operative treatment to the overall treatment of intussusception significantly increased while that of operative manual reduction significantly reduced and bowel resection showed no change. Preoperative utilization of ultrasonography significantly increased while mean duration of admission reduced significantly, but late presentation, morbidity and mortality rates had no significant changes.

Case report: Concurrent intussusception and bleeding marginal ulcer in a patient with gastric bypass.

INTRODUCTION: The source of abdominal pain in patients with a history of gastric bypass can be difficult to determine. Synchronous disease processes may ultimately be the cause of their symptoms. Among the etiologies for hematemesis and obstruction in this population are the diagnoses of marginal ulcer and internal hernia. Given the potential complications of bariatric surgery, it is important to maintain a broad differential diagnosis during the workup of these patients. PRESENTATION: A female with history of laparoscopic Roux-en-Y gastric bypass (RYGB) presented with abdominal pain and hematemesis. Intraoperative findings revealed intussusception of the jejunojejunostomy resulting in obstruction and ischemic bowel. Additionally, a perforated marginal ulcer of the Roux-limb was found to be present. This patient underwent esophagogastroduodenoscopy, bowel resection, jejunojejunostomy revision, and Graham patch repair. DISCUSSION: This case highlights a patient with history of RYGB presenting with obstruction and gastrointestinal bleeding. Although initially diagnosed with internal hernia and Mallory-Weiss hematemesis, surgical exploration revealed concurrent intussusception and marginal ulceration. While intussusception is a rare complication of bariatric surgery, it can occur secondary to mesenteric thinning and motility dysfunction from significant weight loss. It is imperative to maintain a broad differential diagnosis for the causes of obstruction and GI bleeding that include adhesive disease, abdominal wall hernia, internal hernia, intussusception, and marginal ulcers. CONCLUSION: Findings of obstruction or GI bleeding after bariatric surgery may represent a surgical emergency. While these symptoms may be attributed to a single diagnosis, clinicians must consider the presence of synchronous pathologies during the workup of patients.

Single-port laparoscopic surgery for cecum cancer with intussusception: a case report.

BACKGROUND: Most adult cases of intussusception are caused by colorectal cancer, and emergency surgery is performed when symptoms such as abdominal pain and vomiting are present. The patient must customarily undergo both bowel decompression and radical surgery for colorectal cancer at the same time, and laparotomy is generally the procedure of choice. CASE PRESENTATION: An 86-year-old woman presented to our hospital with diarrhea and bloody stools. Preoperative examination revealed the presence of a cancerous tumor in the advanced part of the transverse colon and bowel intussusception. Radical surgery was successfully performed using the laparoscopic single-port technique through a small incision at the umbilical site to treat intussusception caused by cecum cancer. CONCLUSIONS: With only one wound site at the umbilicus, this single-port laparoscopic approach is much less invasive than endoscopic surgery that requires four to five incision wounds to perform the procedure. Furthermore, the patient was discharged without major complications and this surgical technique could be of great benefit if established as a standard procedure in the future.

Application of Delayed Repeated Enema With Sedation in Pediatric Intussusception: A Single Center Retrospective Study.

OBJECTIVE: This study aimed to evaluate the clinical application of delayed repeated air enema (DRE) with sedation in pediatric intussusception. METHOD: We retrospectively assessed cases of idiopathic intussusception treated with air enema reduction at the emergency department of Beijing Children's Hospital affiliated to Capital Medical University from January 2016 to August 2019. The included cases were assigned to the success or failure groups based on the outcomes of DRE with sedation. General patient information, clinical manifestations, test results, and surgical conditions were collected for comparative analysis. RESULTS: A total of 3052 cases were initially diagnosed with intussusception and underwent air enema reduction. Ultimately, 211 cases were included, with 162 in the success group and 49 in the failure group. The success rate of DRE with sedation was 76.8% (162/211), with an overall reduction success rate of 97.8% (2984/3052). Univariate logistic regression analysis showed that patients in the failure group had a significantly higher proportion of patients with age ≤1 year, bloody stools, and left-sided intussusception before DRE compared to the success group (OR = 2.3, 95%CI: 1.1∼4.6, P = 0.023; OR = 3.4, 95%CI: 1.6∼7.2, P = 0.002 and OR = 12.6, 95%CI: 4.6∼34.6, P < 0.001). Multiple logistic regression analysis based on these three factors revealed that the risk of DRE failure was 10.1 times higher in cases with the left-sided intussusception before DRE. CONCLUSIONS: DRE with sedation can improve the overall enema reduction success rate for intussusception and has good feasibility and safety profiles. Left-sided intussusception before DRE is an independent risk factor for enema failure.

[Intestinal Mantle Cell Lymphoma Complicated With Ileocecal Intussusception in Adults:Report of One Case].

Intestinal mantle cell lymphoma complicated with intussusception is rare in clinical practice,lacking specific clinical manifestations.CT and colonoscopy are helpful for the diagnosis of this disease,which need to be distinguished from colorectal cancer,Crohn's disease,and other pathological subtypes of lymphoma.The diagnosis still needs to be confirmed by pathological examination.This paper reports a case of intestinal mantle cell lymphoma complicated with ileocecal intussusception in an adult,aiming to improve the clinical and imaging doctors' understanding of this disease.

Jejunal Undifferentiated Spindle Cell Sarcoma with Intussusception Revealed by 18F-FDG PET/CT.

Spindle cell sarcoma is a malignant tumor with low incidence. They can occur in the soft tissue, bone, or viscera. The characteristics of morphology, density, and metabolism of spindle cell sarcoma are related to the location of the lesion. A 61-year-old woman presented with vomiting after eating for 2 weeks. Signs of peritoneal irritation were involved, but no response for symptomatic treatment included antiemetic and antispasmodic therapy. Abdominal computed tomography (CT) indicated a mass in the intestinal tract in the pelvic cavity. Then, 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/CT was performed, which interestingly detected a jejunal malignancy mass in the left upper abdomen with annular high uptake of 18F-FDG, which was complicated by intussusception and intestinal obstruction. Finally, the jejunal mass was pathologically clarified as an undifferentiated spindle cell sarcoma.

Colo-colonic intussusception as a rare complication of colonoscopy with polypectomy: Two case reports.

BACKGROUND: Colonoscopy is the most frequently used diagnostic and therapeutic tool for the treatment of colorectal diseases. Although the complication rate is low, it can be potentially serious. Intussusception is a rare and severe complication often associated with polypectomy. Only a handful of post-colonoscopy intussusception cases have been reported, making this study a valuable addition to the medical literature. CASE SUMMARY: Case 1: A 61-year-old man underwent colonoscopy with polypectomy for chronic abdominal pain. The patient experienced abdominal pain 11 hours later but was still discharged after pain management. He was readmitted due to recurring pain. Computed tomography (CT) showed colo-colonic intussusception. Initial conservative management and attempts at endoscopic reduction failed; therefore, laparoscopic right hemicolectomy was performed. Histopathological examination revealed tubular adenomas in the polyps and inflammation in the resected specimens. Case 2: A 59-year-old woman underwent colonoscopy with polypectomy for a polyp in the transverse colon. She experienced upper abdominal pain, fever, nausea, and vomiting 9 hours after the procedure. Emergency CT and blood tests revealed a colo-colonic intussusception near the hepatic flexure and an elevated white blood cell count. Initial attempts at endoscopic reduction failed and conservative treatment showed no improvement. She underwent successful laparoscopic reduction and recovered uneventfully. Histopathological examination of the resected polyp revealed hyperplasia. CONCLUSION: Post-colonoscopy intussusception in adults is rare, and polypectomy may contribute to its occurrence. Early diagnosis is crucial, with prompt CT examination serving as key. After excluding malignancies, conservative management and reduction of intussusception should be considered before surgical bowel resection.

Rotavirus vaccination is a protective factor for adverse outcomes in primary intussusception: a single-center retrospective study.

Background: The clinical features and prognosis of intussusception in children vaccinated against rotavirus were undefined. Hence, we conducted the study to explore the clinical characteristics and outcomes of primary intussusception patients who received rotavirus vaccine. Methods: A single-center retrospective study was performed in 327 primary intussusception patients between January 2019 and December 2021. Of these, 168 were vaccinated against rotavirus and 159 were not, the latter serving as the control group. Data on patients' clinical characteristics, commonly used inflammatory biomarkers, treatment, and outcomes were collected and evaluated. Results: Most of the vaccination group received pentavalent rotavirus vaccine produced by Merck, USA (89.88%). There were no differences in demographic characteristics, time from onset to hospital attendance, clinical symptoms and signs between the vaccination group and the control group. The success rate of air enema reduction in the vaccination group was higher than that in the control group (98.21% vs. 88.68%, q=0.01). The vaccination group had lower rates of surgery and complication (1.79% vs. 11.32%, q=0.008; 2.98% vs. 12.58%, q=0.006). Both platelet-lymphocyte ratio (PLR) and C-reactive protein (CRP) levels were lower in the vaccinated group (q=0.02, q=0.004). Higher CRP level [odds ratio (OR): 1.635; 95% confidence interval (CI): 1.248-2.143; P=0.006] and the longer time from onset to hospital attendance (OR: 3.040; 95% CI: 2.418-12.133; P=0.01) were associated with increased adverse events. Rotavirus vaccination (OR: 0.527; 95% CI: 0.103-0.751; P=0.02) was associated with a reduction in the probability of adverse events. Conclusions: Adverse events such as surgery and complications were lower in the vaccination group. Rotavirus vaccination was an independent protective factor for adverse events in patients with primary intussusception.

Colocolic intussusception as a rare cause of intestinal obstruction in a preschool child: A case report.

INTRODUCTION AND IMPORTANCE: Colocolic intussusception occur in less than 5 % of all cases of intussusception. Median age at presentation is 4.4 years. Usually presents with features of intestinal obstruction. Common causes include pathological lead points like juvenile polyps, Meckel's diverticulum and lymphoma. However, rarely occurs without an organic cause as presented in the index case. CASE PRESENTATION: We present a case of colocolic intussusception in a 5-year-old boy with clinical evidence of blood-stained mucoid stools, abdominal distention and post prandial vomiting. CT-scan confirmed the clinical diagnosis. Surgical exploration revealed left-sided colocolic intussusception without a pathological lead point. CLINICAL DISCUSSION: Most cases of colonic intussusception have a pathological lead point. Clinical features are unspecific but mostly present with intestinal obstruction, hence, a CT-scan aids in establishing the diagnosis. CONCLUSION: Colocolic intussusception is a rare subtype of intussusception in the paediatric age group especially in the absence of a pathological lead point. This case report presents a rare case of colocolic intussusception without pathological lead point, highlighting the importance of advanced imaging modalities like CT-scan in establishing the diagnosis and guiding management.

Recurrent Ileocolic Intussusception With the Appendix as the Pathologic Lead Point in Children: A Report of Two Cases and Review of Literature.

Ileocolic intussusception is a consideration in young pediatric patients with acute abdominal pain. Meckel's diverticulum is the most common pathologic lead point for intussusception in children and the appendix acting as the lead point is rare. In addition, management guidelines for recurrent ileocolic intussusception (RICI) are lacking. We present two cases of RICI in which the pathological lead point was the appendix. The first patient, a two-year-old with no medical history, had intermittent abdominal pain and non-bloody vomiting for a month. Ultrasound revealed ileocolic intussusception, successfully managed with pneumatic reduction. However, symptoms recurred and a repeat ultrasound showed partial intussusception of the appendix into the cecum. Laparoscopic reduction and appendectomy were then performed. Symptomatic intussusception recurred, and a second laparoscopic reduction with stump appendectomy resolved all symptoms. The second patient, a three-year-old with no medical history, had colicky abdominal pain for 24 hours. Ultrasound revealed ileocolic intussusception that was pneumatically reduced. As pain recurred, laparoscopic reduction and appendectomy were performed, revealing ileocolic intussusception with a dilated appendix as the pathologic lead point. Recurrent ileocolic intussusception (RICI) with the appendix as the lead point is common, but RICI with the appendix as the lead point is rare. These cases demonstrate the role of the appendix as a pathologic lead point, and a review of the literature supports the need for surgical reduction. While enema reduction is the first line for recurrent intussusception, surgical reduction is preferred when a pathological lead point is suspected.

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue of the ileum in an adult presenting with intussusception: a case report and literature review.

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (EMZL), also known as MALT lymphoma, is an extranodal multiorgan-invasive proliferative lymphoma composed of small B cells with variable morphology. It most commonly occurs in the digestive tract, with a high prevalence in the stomach, but EMZL originating in the small intestine is rare and lacks specificity in clinical manifestations, which makes it easy to be misdiagnosed. Herein, we report a rare case of small intestinal EMZL presentation as intussusception in a 32-year-old man. A colonoscopy performed at the local hospital revealed a pedicled polyp about 5 cm × 5 cm in size with a rough surface, and hyperemia was seen in the ileocecal region. He was admitted to our hospital for a polypectomy. A contrast-enhanced computed tomographic (CT) scan suggested ileocolic intussusception, which was subsequently confirmed by a colonoscopy in our hospital. Adult intussusception is relatively rare, with 90% of cases having a known causative mechanism and 40% of cases caused by primary or secondary malignancies. Therefore, we performed a laparoscopic-assisted right hemicolectomy for the patient. The resected specimen showed that the terminal ileum was intussuscepted into the ascending colon, and the intussusception was hyperemia and edema. A 2.5 cm × 2.5 cm × 1.5 cm mass was seen at the end of the intussusception. Postoperative pathology revealed that the mass was EMZL, partially transformed into a large B-cell lymphoma. The patient was transferred to the hematology department and completed a PET-CT showing postoperative manifestations of primary intestinal lymphoma, Lugano staging IE2. Although EMZL was an indolent lymphoma and the patient was in the early stages, the rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) regimen was given in view of the histological transformation. The patient is in regular follow-up. This was a rare case of small intestinal mass due to EMZL presented as intussusception in adults, which highlighted laparoscopic-assisted enterectomy as a potential therapeutic approach in the multidisciplinary collaborative therapy of small intestine EMZL.

A Case of an Extremely Preterm Infant with Intussusception Triggered by Acquired Cytomegalovirus Infection.

Intussusception is a common cause of intestinal obstruction in infants aged 6-18 months. However, intussusception in preterm neonates (IPN) is an exceedingly rare disorder. The etiology of IPN remains unclear, but common prenatal injuries, such as those causing intestinal hypoxia/hypoperfusion, dysmotility, and strictures, have been proposed as possible contributing factors. Diagnosis is often delayed because the symptoms closely resemble those of necrotizing enterocolitis (NEC). Given the divergent treatments for IPN and NEC, establishing an early and accurate diagnosis is crucial. IPN is predominantly located in the small intestine (91.6%), and ultrasonography proves useful in its diagnosis. We present a case of a very preterm infant who developed intussusception triggered by acquired cytomegalovirus (aCMV) infection, necessitating surgical treatment. The cause of intussusception in this case was diagnosed as aCMV enteritis because no organic lesions were observed in the advanced part of the intussusception. The presence of CMV was confirmed by CMV-DNA-PCR examination of the resected intestinal tract. Intestinal edema and decreased intestinal peristalsis due to aCMV enteritis are likely the primary causes of the intussusception.

Diffuse large B-cell lymphoma-induced intussusception: A case report and literature review.

Adult intussusception necessitates early surgical intervention. We emphasis the significance of considering diffuse large B-Cell lymphoma in differential diagnoses for adult intussusception, particularly in the colon, to ensure precise diagnosis and optimal management.

Rare etiology of colonic intussusception involving an adult with emphysematous cystic enteropathy: A case report and review of literature.

BACKGROUND: Pneumatosis cystoides intestinalis (PCI), characterized by a collection of gas-filled cysts in the intestinal wall, is an uncommon but well-known condition in gastroenterology. Abdominal pain is the most frequent symptom associated with PCI. Intussusception represents a potential cause of recurrent abdominal pain or emergency presentation. However, the occurrence of colonic intussusception secondary to PCI is very unusual in adulthood. CASE SUMMARY: A 52-year-old male, known with idiopathic PCI, presented seventeen months after initial diagnosis with a new right upper quadrant pain. A computed tomography-scan demonstrated a colonic intussusception at the hepatic flexure. PCI did not progress compared with initial investigation. The patient underwent an emergency right hemicolectomy. CONCLUSION: Resection was recommended in this case because PCI proved to be persisting with no identified curable cause. Surgery allowed to address the underlying pathology, the potential relapse of intussusception, and the likely cause of recurrent abdominal pain, either invagination or PCI itself.

Pivotal Surgical Intervention for Pediatric Ileoileal Intussusception With Meckel's Diverticulum: A Case Report.

The most prevalent congenital gastrointestinal tract abnormality is Meckel's diverticulum. It is discovered in most instances incidentally. It can be observed as painless bleeding in the gastrointestinal tract. However, it can occasionally result in acute intestinal obstruction, which frequently masks the actual clinical presentation. This is a case of a four-and-a-half-year-old male child who presented with features of obstruction, which, on further evaluation, revealed ileoileal intussusception. An emergency surgical intervention was planned with an exploratory laparotomy and a reduction of intussusception. This case emphasizes the urgency of diagnosing and managing intussusception to prevent serious consequences such as bowel ischemia, bowel necrosis, bowel perforation, peritonitis, and sepsis. It stands as a stark reminder for medical professionals to stay vigilant for these critical gastrointestinal emergencies, and immediate treatment with a multidisciplinary approach is recommended to significantly enhance patient outcomes.

Adult Ileocolic Intussusception Secondary to Cecal Lipoma: A Case Report.

Large intestinal intussusception is rare in adults. Among potential pathologic lead points for intussusception are lipomas, benign tumors very infrequently found in the large bowel. A 30-year-old woman presented to the emergency department with a chief complaint of generalized abdominal pain for two weeks. A computed tomography scan of her abdomen and pelvis showed an ileocolic intussusception with a lead point of 6.7 cm. The lead point appeared to be predominantly fat. A colonoscopy revealed a large, obstructing lesion in the transverse colon. The patient underwent exploratory laparotomy with a right hemicolectomy, and a pathologic diagnosis of a lipoma was made. The patient recovered from surgery without complications and returned to her normal diet three weeks after discharge. This case highlights an unusual and rare presentation of an ileocolic intussusception caused by a cecal lipoma acting as a lead point.

Peutz-Jeghers syndrome: management for recurrent intussusceptions.

BACKGROUND: Peutz-Jeghers syndrome (PJS) is an autosomal dominant disorder characterized by hamartomatous gastrointestinal polyps along with the characteristic mucocutaneous freckling. Multiple surgeries for recurrent intussusception in these children may lead to short bowel syndrome. Here we present our experience of management in such patients. METHODS: From January 2015 to December 2023, we reviewed children of PJS, presented with recurrent intussusceptions. Data were collected regarding presentation, management, and follow-up with attention on management dilemma. Diagnosis of PJS was based on criteria laid by World Health Organization (WHO). RESULTS: A total of nine patients were presented with age ranging from 4 to 17 years (median 9 years). A total of eighteen laparotomies were performed (7 outside, 11 at our centre). Among 11 laparotomies done at our centre, resection and anastomosis of bowel was done 3 times while 8 times enterotomy and polypectomy was done after reduction of intussusception. Upper and lower gastrointestinal endoscopy (UGIE & LGIE) was done in all cases while intraoperative enteroscopy (IOE) performed when required. Follow-up ranged from 2 months to 7 years. CONCLUSION: Children with PJS have a high risk of multiple laparotomies due to polyps' complications. Considering the diffuse involvement of the gut, early decision of surgery and extensive bowel resection should not be done. Conservative treatment must be tried under close observation whenever there is surgical dilemma. The treatment should be directed in the form of limited resection or polypectomy after reduction of intussusception.

Impact of a 6-12-h delay between ileocolic intussusception diagnostic US and fluoroscopic reduction on patients' outcomes.

BACKGROUND: Image-guided reduction of intussusception is considered a radiologic urgency requiring 24-h radiologist and technologist availability. OBJECTIVE: To assess whether a delay of 6-12 h between US diagnosis and fluoroscopic reduction of ileocolic intussusception affects the success frequency of fluoroscopic reduction. MATERIALS AND METHODS: Retrospective review of 0-5-year-olds undergoing fluoroscopic reduction for ileocolic intussusception from 2013 to 2023. Exclusions were small bowel intussusception, self-reduced intussusception, first fluoroscopic reduction attempt>12 h after US, prior bowel surgery, inpatient status, and patient transferred for recurrent intussusception. Data collected included demographics, symptoms, air/contrast enema selection, radiation dose, reduction failure, 48-h recurrence, surgery, length of stay, and complications. Comparisons between<6-h and 6-12-h delays after ultrasound diagnosis were made using chi-square, Fisher's exact test, and Mann-Whitney U tests (P< 0.05 considered significant). RESULTS: Of 438 included patients, 387 (88.4%) were reduced in <6 h (median age 1.4 years) and 51 (11.7%) were reduced between 6 and 12 h (median age 2.05 years), with median reduction times of 1:42 and 7:07 h, respectively. There were no significant differences between the groups for reduction success (<6 h 87.3% vs. 6-12 h 94.1%; P-value = 0.16), need for surgery (<6 h 11.1% vs. 6-12 h 3.9%; P-value=0.112), recurrence of intussusception within 48 h after reduction (<6 h 9.3% vs. 6-12 h 15.7%; P-value=0.154), or length of hospitalization (<6 h 21:07 h vs. 6-12 h 20:03 h; P-value=0.662). CONCLUSION: A delay of 6-12 h between diagnosis and fluoroscopic reduction of ileocolic intussusception is not associated with reduced fluoroscopic reduction success, need for surgical intervention after attempted reduction, recurrence of intussusception following successful reduction, or hospitalization duration after reduction.

Recalcitrant intussusception: exploring potential associations with Helicobacter pylori infection - a case report and literature review.

BACKGROUND: Intussusception, a common cause of abdominal pain in children, often lacks clear underlying causes and is mostly idiopathic. Recurrence, though rare, raises clinical concerns, with rates escalating after each episode. Factors like pathological lead points and Henoch-Schönlein purpura (HSP) are associated with recurrent cases. On the other hand, the prevalence of Helicobacter pylori (H. pylori), often asymptomatic, in children has been declining. Although its infection is reported to be linked with HSP, its role in recurrent intussusception remains unexplored. Further research is needed to understand the interplay among H. pylori (culprit pathogen), HSP (trigger), and intractable intussusception so as to develop effective management strategies. CASE PRESENTATION: A two-year-old girl experienced four atypical episodes of intussusception at distinct locations, which later coincided with HSP. Despite treatment with steroids, recurrent intussusception persisted, suggesting that HSP itself was not a major cause for intractable presentations. Subsequent identification of H. pylori infection and treatment with triple therapy resulted in complete resolution of her recalcitrant intussusception. CONCLUSION: This instructive case underscored a sequence wherein H. pylori infection triggered HSP, subsequently resulting in recurrent intussusception. While H. pylori infection is not common in young children, the coexistence of intractable intussusception and steroid-resistant recurrent HSP necessitates consideration of H. pylori infection as a potential underlying pathogen.

Postoperative intussusception in children operated for primary intussusception - A very rare entity.

Postoperative intussusception (POI) after abdominal and non-abdominal operations is a rare but recognized condition discussed several times in literature. There are scarce reports regarding POI in children operated primarily for intussusception. We discuss three such cases that were seen in our institution in the last two years. The patients showed symptoms of atypical ileus that failed to resolve two to eight days following primary surgery. Ultrasound reported intussusception and surgical intervention was sought. All patients had ileoileal intussusception. Manual reduction was successful in two cases. One had intestinal necrosis and underwent resection and anastomosis. Recovery was satisfactory without recurrence. POI should be suspected in patients who show signs of intestinal obstruction in early postoperative period. A second POI should be kept in mind after surgical reduction of the first intussusception. Ultrasound should be performed to aid diagnosis followed by urgent surgical intervention.
