Evaluation of Intussusception Following Pentavalent Rotavirus Vaccine (RotaTeq) Administration in 5 African Countries.

BACKGROUND: A low-level risk of intussusception following rotavirus vaccination has been observed in some settings and may vary by vaccine type. We examined the association between RotaTeq vaccination and intussusception in low-income settings in a pooled analysis from 5 African countries that introduced RotaTeq into their national immunization program. METHODS: Active surveillance was conducted at 20 hospitals to identify intussusception cases. A standard case report form was completed for each enrolled child, and vaccination status was determined by review of the child's vaccination card. The pseudo-likelihood adaptation of self-controlled case-series method was used to assess the association between RotaTeq administration and intussusception in the 1-7, 8-21, and 1-21 day periods after each vaccine dose in infants aged 28-245 days. RESULTS: Data from 318 infants with confirmed rotavirus vaccination status were analyzed. No clustering of cases occurred in any of the risk windows after any of the vaccine doses. Compared with the background risk of naturally occurring intussusception, no increased risk was observed after dose 1 in the 1-7 day (relative incidence = 2.71; 95% confidence interval [CI] = 0.47-8.03) or the 8-21 day window (relative incidence = 0.77; 95%CI = 0.0-2.69). Similarly, no increased risk of intussusception was observed in any risk window after dose 2 or 3. CONCLUSIONS: RotaTeq vaccination was not associated with increased risk of intussusception in this analysis from 5 African countries. This finding mirrors results from similar analyses with other rotavirus vaccines in low-income settings and highlights the need for vaccine-specific and setting-specific risk monitoring.

Small bowel intussusception - aetiology & management.

PURPOSE OF REVIEW: Adult small bowel intussusception (SBI) differs in incidence, symptomatology and management from the more commonly encountered paediatric intussusception. This review spans across the multitude of causes of adult SBI, and summarises the diagnostic work-up and management options according to recent literature. RECENT FINDINGS: There has been an increase in use of small bowel capsule endoscopy and point-of-care ultrasound for the diagnosis of acute adult SBI. SUMMARY: A high degree of suspicion of a malignant cause of SBI is required in the adult population. Alarm clinical features include weight loss, history of malignancy, and iron deficiency anaemia. CT remains the gold standard imaging technique as it may identify the lead point and thus aid in endoscopic or surgical management. If malignancy is excluded and no lead point is identified, serology and histology may be helpful to look for inflammatory, infective and autoimmune aetiology.

A comprehensive scoring system for the better prediction of bowel resection in pediatric intussusception.

BACKGROUND: Intussusception presents a significant emergency that often necessitates bowel resection, leading to severe complications and management challenges. This study aims to investigate and establish a scoring system to enhance the prediction of bowel resection necessity in pediatric intussusception patients. METHODS: This retrospective study analyzed 660 hospitalized patients with intussusception who underwent surgical management at a pediatric hospital in Southwest China from April 2008 to December 2020. The necessity of bowel resection was assessed and categorized in this cohort. Variables associated with bowel resection were examined using univariate and multivariate logistic regression analyses. Based on these analyses, a scoring system was developed, grounded on the summation of the coefficients (ß). RESULTS: Among the 660 patients meeting the inclusion criteria, 218 required bowel resection during surgery. Bowel resection occurrence was linked to an extended duration of symptoms (Odds Ratio [OR] = 2.14; 95% Confidence Interval [CI], 1.03-5.23; P = 0.0015), the presence of gross bloody stool (OR = 8.98; 95% CI, 1.76-48.75, P < 0.001), elevated C-reactive protein levels (OR = 4.79; 95% CI, 1.12-28.31, P = 0.0072), lactate clearance rate (LCR) (OR = 17.25; 95% CI, 2.36-80.35; P < 0.001), and the intussusception location (OR = 12.65; 95% CI, 1.46-62.67, P < 0.001), as determined by multivariate logistic regression analysis. A scoring system (totaling 14.02 points) was developed from the cumulative ß coefficients, with a threshold of 5.22 effectively differentiating infants requiring surgical intervention from others with necrotizing enterocolitis (NEC), exhibiting a sensitivity of 78.3% and a specificity of 71.9%. CONCLUSIONS: This study successfully identified multiple risk factors for bowel resection and effectively used a scoring system to identify patients for optimal clinical management.

Lymphoma-related intussusception in children: diagnostic challenges and clinical characteristics.

Intussusception is a common cause of acute abdominal pain in children and the most frequent cause of intestinal obstruction in infants. Although often idiopathic, it can stem from conditions like lymphoma. This study delves into lymphoma-related intussusception in children, aiming to enhance early detection and management. A retrospective review encompassed children admitted from 2012 to 2023 with intussusception due to intestinal lymphoma. Demographic, clinical, and imaging data were meticulously extracted and analyzed. The study included 31 children in the lymphoma-related intussusception group. Contrasted with non-lymphoma-related cases, the patients of lymphoma-related intussusception were notably older (median age: 87 months vs. 18.5 months), predominantly male, and demonstrated protracted abdominal pain. Ultrasound unveiled mesenteric lymph node enlargement and distinct intra-abdominal masses; enema reduction success rates were notably diminished. Detecting lymphoma-related intussusception remains intricate. Age, prolonged symptoms, and distinctive ultrasound findings can arouse suspicion. Timely surgical intervention, based on preoperative imaging, proves pivotal for accurate diagnosis. CONCLUSION:  Swift identification of lymphoma-related intussusception, distinguished by unique clinical and ultrasound features, is imperative for timely intervention and treatment. Further research is warranted to refine diagnostic approaches. WHAT IS KNOWN: • Intussusception in pediatric patients can be caused by a wide spectrum of underlying diseases including lymphoma. • Early Identifying the exact underlying cause of intussusception is crucial for tailored therapy, however often challenging and time-consuming. WHAT IS NEW: • Lymphoma-related intussusception may present with increased abdominal fluid accumulation, intestinal obstruction, and a higher likelihood of failed reduction during enema procedures. • For high-risk children, repeated ultrasound examinations or further investigations may be necessary to confirm the diagnosis.

Yield of abdominal radiographs in children with suspected intussusception; rate of pneumoperitoneum and other abdominal pathology.

OBJECTIVES: Ultrasound is the criterion standard imaging modality for the diagnosis of intussusception. However, to our knowledge the utility of abdominal radiographs to concurrently screen for pneumoperitoneum or other abdominal pathology that could have a similar presentation has not been studied. Our institutional protocol requires the performance of AP supine and left lateral decubitus views of the abdomen prior to ultrasound evaluation for intussusception, providing an opportunity to examine the yield of abdominal radiographs in this setting. Our primary objective was to determine the rate of pneumoperitoneum on screening abdominal radiographs in children undergoing evaluation for intussusception. Our secondary objective was to determine the rate that other clinically significant pathology is found on these screening abdominal radiographs. METHODS: We performed a retrospective chart review of all patients under 6 years of age who had any imaging ordered in our large urban pediatric emergency department to evaluate for suspected intussusception during the calendar years 2018-2020. RESULTS: 1115 patient encounters met our inclusion criteria. Among 1090 who had screening abdominal radiographs, 82 (8%) had findings concerning for intussusception. Of those not concerning for intussusception, 635 (58%) were read as normal, 263 (24%) showed moderate to large stool burden, 107 (10%) showed generalized bowel distention, and 22 (2%) showed abnormal gastric distention. Individually the remainder of all other findings compromised <1% of encounters and included radiopaque foreign body (8), intraabdominal calcification (4), pneumonia/effusion (3), pneumatosis intestinalis, abdominal mass (2), diaphragmatic hernia (1), rib fracture (1), appendicolith (1), feeding tube malposition (1), and bowel wall thickening (1). In one encounter the patient had a bowel perforation with pneumoperitoneum present secondary to ingestion of multiple magnets. CONCLUSIONS: Our study indicates that radiograph-detected pneumoperitoneum is rare in children with suspected intussusception. Constipation is the most common abnormal finding on screening radiographs. Other findings occur in approximately 15% of total cases, some of which require further workup.

Two cases of small bowel necrosis due to intussusception secondary to abnormal proliferation of intestinal Peyer's patches in infants after MMR vaccination.

BACKGROUND: Intussusception is one of the most common acute abdominal conditions in pediatric patients, and if left untreated, it may result in intestinal necrosis and even death. The etiology of the disease is unknown and may be related to a variety of factors, and there are only limited reports of small bowel necrosis secondary to abnormal Peyer's node hyperplasia after MMR vaccination. CASE PRESENTATION: In this report, we present two infants who had an abnormal proliferation of Peyer's nodes secondary to intussusception eventually leading to small bowel necrosis after MMR vaccination. CONCLUSIONS: Intestinal necrosis and infectious shock are the most common causes of infant mortality, and early detection and management are critical.

Clinical features of intussusception in children secondary to small bowel tumours: a retrospective study of 31 cases.

BACKGROUND: Summarizing the clinical features of children with intussusception secondary to small bowel tumours and enhancing awareness of the disease. METHODS: Retrospective summary of children with intussusception admitted to our emergency department from January 2016 to January 2022, who underwent surgery and were diagnosed with small bowel tumours. Summarize the types of tumours, clinical presentation, treatment, and prognosis. RESULTS: Thirty-one patients were included in our study, 24 males and 7 females, with an age of onset ranging from 1 m to 11y 5 m. Post-operative pathology revealed 4 types of small intestinal tumour, 17 lymphomas, 10 adenomas, 4 inflammatory myofibroblastomas and 1 lipoma. The majority of tumours in the small bowel occur in the ileum (83.9%, 26/31). Abdominal pain, vomiting and bloody stools were the most common clinical signs. Operative findings indicated that the small bowel (54.8%, 17/31) and ileocolic gut were the main sites of intussusception. Two types of procedure were applied: segmental bowel resection (28 cases) and wedge resection of mass in bowel wall (3 cases). All patients recovered well postoperatively, with no surgical complications observed. However, the primary diseases leading to intussusception showed slight differences in long-term prognosis due to variations in tumor types. CONCLUSIONS: Lymphoma is the most common cause of intussusception in pediatric patients with small bowel tumours, followed by adenoma. Small bowel tumours in children tend to occur in the ileum. Therefore, the treatment of SBT patients not only requires surgeons to address symptoms through surgery and obtain tissue samples but also relies heavily on the expertise of pathologists for accurate diagnosis. This has a significant impact on the overall prognosis of these patients.

Clinical characteristics and risk factors of IgA vasculitis with intussusception and intestinal perforation.

AIM: Intussusception is the most common surgical complication of IgA vasculitis (IgAV), and intestinal perforation is usually associated with intussusception. If they are not recognised and treated in a timely manner, serious consequences may occur. The objective is to summarise the clinical features of IgAV complicated by intussusception and intestinal perforation and explore its risk factors. METHODS: The clinical data of 32 patients with IgAV complicated by surgical complications (25 cases of intussusception and 7 cases of intestinal perforation) were retrospectively analysed. A total of 160 IgAV children with gastrointestinal (GI) involvement but without surgical complications were randomly selected as a control group. Binary logistic regression analysis was performed to explore the risk factors for IgAV with intussusception and intestinal perforation. RESULTS: Compared with the intussusception group, the intestinal perforation group had a significantly higher number of patients with GI symptoms prior to skin purpura and GI bleeding, a significantly higher number of days of abdominal pain, a significantly higher Wong-Baker score, and a significantly higher white blood cell count. Multivariate logistic regression analysis indicated that age ≤7 years, GI symptoms prior to skin purpura, abdominal pain intensity (Wong-Baker scale) and timing of glucocorticoid treatment were independent risk factors of IgAV with intussusception and intestinal perforation. CONCLUSION: Age less than 7 years, severe abdominal pain, and GI symptoms prior to skin purpura were risk factors for IgAV with intussusception and intestinal perforation. Early use of glucocorticoids may prevent intussusception and intestinal perforation.

Intussusception reduction methods in daily practice-a survey by the European Society of Paediatric Radiology Abdominal Imaging Taskforce.

BACKGROUND: Image-guided intussusception reduction has been practised internationally for many decades. The use of different modalities, delayed repeat attempts, and sedation/anaesthesia are unknown. OBJECTIVE: To survey the practice of image-guided intussusception reduction. MATERIALS AND METHODS: A 20-point questionnaire created by the European Society of Paediatric Radiology (ESPR) Abdominal Imaging Taskforce was distributed via the ESPR members' mailing list and shared on social media between 28 March and 1 May 2023. RESULTS: There were 69 responses from 65 worldwide institutions, with a mean of 18 intussusception reductions performed per year: 55/69 (80%) from 52 European institutions and 14/69 (20%) from 13 institutions outside of Europe. European centres reported using 19/52 (37%) fluoroscopy, 18/52 (35%) ultrasound, and 15/52 (28%) a mixture of both, with 30/52 (58%) offering a delayed repeat at 15 min to 24 h. Non-European centres reported using 5/13 (39%) fluoroscopy, 6/13 ultrasound (46%), and 2/13 (15%) a mixture of both, with 9/13 (69%) offering a delayed repeat attempt. Sedation or analgesia was used in 35/52 (67%) of European and 2/13 (15%) non-European institutions. CONCLUSION: There is wide variation in how image-guided intussusception reduction is performed, and in the use of sedation/anaesthesia.

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.

Pushing Backwards: Evaluating Effectiveness of Conservative Treatment of Intestinal Intussusception.

OBJECTIVE: Intestinal intussusception (II) is a common cause for acute abdomen in children, occurring in 0.33 to 0.71 per 1000 children per year. Early diagnosis and treatment are fundamental for prevention of irreversible intestinal damage. The first line of treatment is conservative, with saline reduction enema or air reduction enema. Our goal is to evaluate results with conservative treatment of II in children. METHODS: A retrospective single-center review of all patients with diagnosis of II from January 2014 to December 2019 was performed. Demographics, clinical data, treatment option, and results were assessed. RESULTS: Thirty-eight cases were identified. The mean age was 26 months, and 68% were males. Most presented with abdominal pain (95%) and vomiting (66%), after an average of 30 hours. Rectal bleeding was present in 32% of patients. Abdominal ultrasound was performed in all patients for diagnosis. Conservative treatment was first option in 95% of patients, with a global effectiveness of 83% after 1 attempt. Saline reduction enema was more effective than air reduction enema (88% vs 70%), and patients with successful reduction were younger (24 vs 33 months), but neither reached statistical significance. Two patients had a subsequent II episode within 1 week after hospital discharge. Neither age, sex, symptoms and respective duration, rotavirus inoculation, intussuscepted bowel length, nor technique used was predictive of treatment failure or II relapse. CONCLUSIONS: Conservative treatment in II is a safe and effective option, preventing invasive surgical procedures. Effectiveness of such treatments may be as high as 88% after 1 attempt, with rapid diet reintroduction. Same-day discharge after oral feeding toleration is safe.

Enteroenteric intussusception caused by a small bowel metastatic cutaneous melanoma.

Unlike in children, intussusception is very rare in adults and accounts for only 1% of ileus in that population. While intussusception in children is most often idiopathic, in adults the cause of intussusception in most cases is tumor and most often metastatic adenocarcinoma. It is an extremely rare phenomenon for intestinal melanoma metastasis to be the cause of intussusception and has been described in the literature so far only in a limited number of case reports. 41-year-old female patient was admitted to the emergency department with a clinical picture of ileus. The patient had a melanoma excision on her back five years ago, for which chemotherapy and radiotherapy were carried out. An MSCT of the abdomen was performed, which indicated an obstructive ileus of the small intestine with a typical sign of intussusception (target sign). Upon explorative laparotomy enteroenteric intussusception was found with an invaginated segment of the ileum in a length of about 20 cm. When the intussuscepted segment was reduced, a black tumor the size of a plum was verified as a leading point. Histological analysis indicated metastatic cutaneous melanoma with foci of melanocytes underneath normal intestinal epithelium.

Colonic gastrointestinal stromal tumor (GIST) presenting with colocolonic intussusception: A rare case report.

An 8-year-old spayed female British bulldog was presented with vomiting, hyporexia, and large-bowel diarrhea. Abdominal ultrasound revealed a focal colonic mass with an intussusception located immediately oral to the mass. The intussusception encompassed the ascending and transverse colon and was non-reducible. Colonic resection and anastomosis were completed to include the intussusception and colonic mass. Histopathological examination of the mass demonstrated a spindle cell neoplasm arising within the muscular wall of the intussuscepted segment that obliterated normal architecture. Mild-to-moderate cytoplasmic immunoreactivity of the tumor cell population for CD117 and smooth muscle actin was consistent with a diagnosis of a gastrointestinal stromal tumor. The dog described herein remains alive and free of progressive disease at the time of writing. Key clinical message: The entire gastrointestinal tract should be evaluated in any animal with gastrointestinal symptoms. A gastrointestinal stromal tumor remains a plausible differential diagnosis, regardless of the intestinal segment affected, and tumorassociated intussusception is a rare but urgent clinical finding.

Tumeur stromale gastro-intestinale du côlon (GIST) présentant une invagination colocolique : un rapport de cas rare. Une femelle bouledogue anglais stérilisée de 8 ans a présenté des vomissements, une hyporexie et une diarrhée d'origine du gros intestin. L'échographie abdominale a révélé une masse colique focale avec une invagination située immédiatement oralement à la masse. L'intussusception englobait le côlon ascendant et transverse et était non réductible. La résection colique et l'anastomose ont été réalisées pour inclure l'intussusception et la masse colique. L'examen histopathologique de la masse a révélé un néoplasme à cellules fusiformes apparaissant dans la paroi musculaire du segment invaginé qui a oblitéré l'architecture normale. L'immunoréactivité cytoplasmique légère à modérée de la population de cellules tumorales pour le CD117 et l'actine des muscles lisses étaient compatibles avec un diagnostic de tumeur stromale gastro-intestinale. Le chien décrit ici est toujours vivant et exempt de maladie évolutive au moment de la rédaction.Message clinique clé :L'ensemble du tractus gastro-intestinal doit être évalué chez tout animal présentant des symptômes gastrointestinaux. Une tumeur stromale gastro-intestinale reste un diagnostic différentiel plausible, quel que soit le segment intestinal atteint, et l'intussusception associée à la tumeur est une constatation clinique rare mais urgente.(Traduit par Dr Serge Messier).

[Ileo-colic intussusception in adult secondary to a large neoplasia of the lower caecal fundus]. / L'image du mois. Invagination iléo-colique chez l'adulte secondaire à une volumineuse néoplasie du bas-fond caecal.

Intussusception is rare in adults, accounting for 1 to 5 % of mechanical bowel obstructions. It is due to pathologic lead point within the bowel which is malignant in up to 77 % of cases. Benign lesions may also be responsible for intussusception (polyp, Meckel diverticulum). The lead point is pulled forward by normal peristaltism, prolapsing the affected segment of bowel into another segment. The most common presentation in adults is intermittent abdominal pain and bowel obstruction (nausea, vomiting, inability to pass gas or stools). Abdominal scanner is the key exam for the diagnosis and the treatment is always surgical resection.

Les invaginations grêles et coliques sont rares chez l'adulte, représentant 1 à 5 % des causes d'obstruction digestive mécanique. Elles sont le plus souvent causées par une masse intra-digestive, le péristaltisme entraînant un prolapsus du segment malade vers un segment intestinal adjacent. Elles sont généralement le reflet d'une pathologie maligne du tube digestif (tumeur maligne découverte dans plus de 77 % des cas), mais il peut également exister des causes béniqnes (polype, diverticule de Meckel, adénopathie) . Elles se manifestent sous forme de douleurs abdominales et d'occlusion (nausées, vomissements, arrêt des selles et des gaz). Le scanner abdominal est l'examen de choix pour poser le diagnostic. Le traitement est toujours une résection chirurgicale.

Point-of-care ultrasound for the diagnosis of an atypical small bowel obstruction in a cannabis user: a case report.

This case report describes an atypical small bowel obstruction in a 71- years old cannabis user and how point-of-care of ultrasound (PoCUS) helped to its management by further orientating the physician toward the bowel obstruction etiology, namely intussusception. Intussusception is the invagination of an intestinal segment into the adjacent segment. The acute clinical presentation of intussusception often has non-specific symptoms, and the diagnosis can be challenging. While the most common etiology is neoplasm, intussusception also occurs in bowel motility disorder such as after cannabis use. Although this case report illustrates intussusception PoCUS findings, these should nevertheless be integrated into the clinical picture and CT-scan should remain the gold standard complementary examination in case of a suspected bowel obstruction.

Intussusception after Rotavirus Vaccine Introduction in India.

BACKGROUND: A three-dose, oral rotavirus vaccine (Rotavac) was introduced in the universal immunization program in India in 2016. A prelicensure trial involving 6799 infants was not large enough to detect a small increased risk of intussusception. Postmarketing surveillance data would be useful in assessing whether the risk of intussusception would be similar to the risk seen with different rotavirus vaccines used in other countries. METHODS: We conducted a multicenter, hospital-based, active surveillance study at 27 hospitals in India. Infants meeting the Brighton level 1 criteria of radiologic or surgical confirmation of intussusception were enrolled, and rotavirus vaccination was ascertained by means of vaccination records. The relative incidence (incidence during the risk window vs. all other times) of intussusception among infants 28 to 365 days of age within risk windows of 1 to 7 days, 8 to 21 days, and 1 to 21 days after vaccination was evaluated by means of a self-controlled case-series analysis. For a subgroup of patients, a matched case-control analysis was performed, with matching for age, sex, and location. RESULTS: From April 2016 through June 2019, a total of 970 infants with intussusception were enrolled, and 589 infants who were 28 to 365 days of age were included in the self-controlled case-series analysis. The relative incidence of intussusception after the first dose was 0.83 (95% confidence interval [CI], 0.00 to 3.00) in the 1-to-7-day risk window and 0.35 (95% CI, 0.00 to 1.09) in the 8-to-21-day risk window. Similar results were observed after the second dose (relative incidence, 0.86 [95% CI, 0.20 to 2.15] and 1.23 [95% CI, 0.60 to 2.10] in the respective risk windows) and after the third dose (relative incidence, 1.65 [95% CI, 0.82 to 2.64] and 1.08 [95% CI, 0.69 to 1.73], respectively). No increase in intussusception risk was found in the case-control analysis. CONCLUSIONS: The rotavirus vaccine produced in India that we evaluated was not associated with intussusception in Indian infants. (Funded by the Bill and Melinda Gates Foundation and others.).

Does Rectoanal Intussusception Limit Improvements in Clinical Outcome and Quality of Life After Sacral Nerve Stimulation for Fecal Incontinence?

BACKGROUND: Sacral nerve stimulation is a treatment option for severe, medically refractory fecal incontinence, although its use in patients with anatomic abnormalities remains controversial. OBJECTIVE: This study aimed to determine whether patients with rectoanal intussusception achieve similar benefits from device implantation to patients without rectoanal intussusception. DESIGN: Retrospective review of a prospectively maintained database. Demographics and clinical data were collected for each patient, including preoperative pelvic floor testing. Defecographies were reanalyzed in a blinded manner. Preoperative rectoanal intussusception was determined on the basis of the Oxford system (grade III-IV vs not; grade V excluded). SETTINGS: Academic-affiliated pelvic health center. PATIENTS: All patients undergoing sacral nerve stimulation for fecal incontinence between July 2011 and July 2019. MAIN OUTCOME MEASURES: Cleveland Clinic Florida Incontinence/Wexner Scores, Fecal Incontinence Severity Indices, and Fecal Incontinence Quality of Life Indices at 1 year. RESULTS: One hundred sixty-nine patients underwent sacral nerve stimulation for fecal incontinence during the study period. The average age was 60.3 years and 91% were female. Forty-six patients (27.2%) had concomitant rectoanal intussusception (38 patients [22.5%] grade III and 8 patients [4.7%] grade IV). Before surgery, patients reported an average of 10.8 accidents per week and a Wexner score of 15.7, with no difference between patients with and without rectoanal intussusception ( p = 0.22 and 0.95). At 1 year after surgery, the average Wexner score was 9.5. There was no difference in postoperative Wexner scores (10.4 vs 9.2, p = 0.23) or improvement over time between patients with and without rectoanal intussusception (-6.7 vs -5.7, p = 0.40). Similarly, there was no difference in quality of life or frequency of incontinence to liquid or solid stool. LIMITATIONS: Single-institution, moderate sample size, incomplete survey response. CONCLUSIONS: Concomitant rectoanal intussusception does not appear to affect clinical outcomes or quality of life after sacral nerve stimulation for fecal incontinence. Appropriate patients with fecal incontinence and rectoanal intussusception can be considered for sacral nerve stimulation placement. See Video Abstract at http://links.lww.com/DCR/C192 .

La edad promedio fue de 60.3 años y el 91% eran mujeres. Cuarenta y seis pacientes (27.2%) tenían intususcepción rectoanal concomitante (38 [22.5%] grado III y 8 [4.7%] grado IV). Antes de la cirugía, los pacientes informaron un promedio de 10.8 accidentes por semana y una puntuación de Wexner de 15.7 sin diferencia entre pacientes con y sin intususcepción rectoanal (p = 0.22 y 0.95). Un año después de la cirugía, la puntuación promedio de Wexner fue de 9.5. No hubo diferencia en las puntuaciones de Wexner posoperatorias (10.4 frente a 9.2, p = 0.23) o mejoría con el tiempo entre los pacientes con y sin intususcepción rectoanal (-6.7 frente a -5.7, p = 0.40). De manera similar, no hubo diferencia en la calidad de vida o la frecuencia de incontinencia de heces líquidas o sólidas.LIMITACIONES:Institución única, tamaño de muestra moderado, respuesta de encuesta incompleta.CONCLUSIÓN:La intususcepción rectoanal concomitante no parece afectar los resultados clínicos o la calidad de vida después de la neuroestimulación sacra para la incontinencia fecal. Los pacientes apropiados con incontinencia fecal e intususcepción rectoanal pueden ser considerados para la neuroestimulación sacra.

The association between levator plate integrity and pelvic floor defaecatory dysfunction.

AIMS: Levator ani deficiency has been implicated in anterior pelvic floor pathology but its association with pelvic floor defaecatory dysfunction is less clear. The aim was to examine the relationship of levator ani deficiency with anatomical abnormalities (rectocoele, intussusception, enterocoele, perineal descent) and patient symptoms (bowel, vagina) in patients with pelvic floor defaecatory dysfunction. METHODS: The prospective observational case series of 223 women presenting to a tertiary colorectal pelvic floor unit with defaecatory dysfunction. Each underwent assessment with symptom severity and quality of life (QoL) scores, integrated total pelvic floor ultrasound (PFUS) (transvaginal, transperineal) and defaecation proctography (DP). Rectocoele, intussusception, enterocoele and perineal descent were assessed on both. Levator ani deficiency was scored using endovaginal ultrasound (score 0-18; mild [0-6], moderate [>6-12], severe [>12-18]). RESULTS: The proportion of patients with rectocoele, enterocoele, and intussusception increased with increasing levator ani damage (mild, moderate, severe). There was a weakly positive correlation between size of rectocoele and levator ani deficiency. On PFUS, there was a weakly positive correlation between severity of intussusception and enterocoele with levator ani deficiency. On DP, there was a weakly positive correlation between perineal descent and levator ani deficiency. There was no association between bowel symptom and QoL scores and levator ani deficiency. Vaginal symptoms were associated with levator ani deficiency. CONCLUSIONS: Anatomical abnormalities which are implicated in pelvic floor defaecatory dysfunction (rectocoele, intussusception, enterocoele, perineal descent) were associated with worsening levator ani deficiency. There was no association between bowel symptoms and levator ani deficiency. Vaginal symptoms were associated with levator ani deficiency.

Is posterior compartment prolapse associated with anal incontinence?

OBJECTIVE: It has been claimed that manifestations of posterior compartment prolapse, such as rectocele, enterocele and intussusception, are associated with anal incontinence (AI), but this has not been studied while controlling for anal sphincter trauma. We aimed to investigate this association in women with intact anal sphincter presenting with pelvic floor dysfunction. METHODS: This retrospective study analyzed 1133 women with intact anal sphincter presenting to a tertiary urogynecological center for pelvic floor dysfunction between 2014 and 2016. All women underwent a standardized interview, including assessment of symptoms of AI, clinical examination and three-/four-dimensional transperineal ultrasound. Descent of the rectal ampulla, true rectocele, enterocele, intussusception and anal sphincter trauma were diagnosed offline. RESULTS: Mean age was 54.1 (range, 17.6-89.7) years and mean body mass index was 29.4 (range, 14.7-67.8) kg/m2 . AI was reported by 149 (13%) patients, with a median St Mark's anal incontinence score of 12 (interquartile range, 1-23). Significant posterior compartment prolapse was seen in 693 (61%) women on clinical examination. Overall, 638 (56%) women had posterior compartment prolapse on imaging: 527 (47%) had a true rectocele, 89 (7.9%) had an enterocele and 26 (2.3%) had an intussusception. Women with ultrasound-diagnosed enterocele had a significantly higher rate of AI (23.6% vs 12.3%; odds ratio (OR), 2.21 (95% CI, 1.31-3.72); P = 0.002), but when adjusted for potential confounders, this association was no longer significant (OR, 1.56 (95% CI, 0.82-2.77); P = 0.134). CONCLUSION: In women without anal sphincter trauma, posterior compartment prolapse, whether diagnosed clinically or by imaging, was not shown to be associated with AI. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Length of Bowel Rest Does Not Predict Gastrojejunostomy Tube-Associated Intussusception Recurrence.

OBJECTIVES: One potential treatment for gastrojejunostomy (GJ) tube-related intussusception is bowel rest, whereby the GJ tube is replaced with a gastrostomy tube. The aim of this study was to determine whether bowel rest length was associated with decreased risk of re-intussusception. METHODS: Pediatric patients with GJ tube-related intussusceptions were identified during the study period of January 1, 2010 and August 1, 2021. Records were reviewed for demographics, symptoms, need for central access to initiate parenteral nutrition, and length of stay. Comparison was made between patients with intussusception recurrence within 30 days and those without. Those undergoing earlier replacement, defined as the first quartile of rest time, or 72 hours, were then compared to longer periods of bowel rest. RESULTS: Forty-six intussusceptions were included, with a median age of 2.8 years (interquartile range, IQR: 1.4-4.1) and weight of 12 kg (IQR: 8.9-15.4). All patients diagnosed as outpatient (54.3%) required hospital admission and 9 of 46 (19.6%) required central access. There were 7 recurrences (15.2%). There was no difference in recurrence based on time of bowel rest (5 days in those without vs 6 days in those with, P = 0.30) nor a difference in recurrence with <72 hours of bowel rest compared to >72 hours (1/15, 6.7% vs 6/31, 19.3%). Patients undergoing earlier exchange had a shorter median length of hospital stay (3 vs 8.5 days, P = 0.003). CONCLUSION: Length of bowel rest was not associated with recurrent GJ tube-related intussusceptions. If bowel rest is utilized, <72 hours may be sufficient to decrease length of hospital stay.
