The Changing Face of Childhood Intussusception: A Refinement in the Technique of Saline Reduction and Outcome.

Aims: Intussusception is a common pediatric surgical emergency and an indicator for primary healthcare. We report our experience with childhood intussusception at a tertiary care hospital in the private sector in Central Kerala and add our refinement to the technique of hydrostatic saline reduction which had more desirable outcome. Settings and Design: Children presenting with the diagnosis of intussusception which were managed in our department of pediatric surgery at a private hospital in Kerala, India. Subjects and Methods: Eighty children, up to 15 years of age, (43 boys, 37 girls) confirmed to have intussusception on ultrasound and managed in our institution from October 2016 to July 2020 with hydrostatic saline reduction. Sixty-two (77%) of them were aged 3 months to 3 years (numbers <10 to be written in words); the age of idiopathic intussusception. Statistical Analysis Used: SPSS V25. Association between variables using Chi square test and independent t test. Results: A total of 80 children met the criteria out of that (n = 79) had successful nonoperative reduction. Hydrostatic saline enema 73, One Barium and five air enema. A child presented in shock was taken up for laparotomy and reduced operatively. Six recurred within 24 h (7% early recurrence) and a second attempt at nonoperative reduction succeeded in all six of them. (numbers <10 in words). Eleven children (14%) had a late recurrence, the attempt at saline hydrostatic reduction was successful in only 3 (27%) and 8 went on to have surgery. Six were successfully reduced operatively and 2 had resection anastomosis. Conclusions: After excluding those who need surgery on clinical grounds, we report a 98.7% success with nonoperative reduction for the first instance of intussusception, a 24 h recurrence of 7%, with successful repeat reductions in all. With the refinement in the technique, we could achieve a desirable outcome. At the first presentation, surgery was indicated in 1 of the 80 children. We report a late recurrence rate of 14%, with a 27% success rate for nonoperative reduction. No pathological lead points were identified even in this group. All the children had an uneventful and a faster recovery. In our series, we had 97.5% follow-up rate.

Novel laparo-endoscopic hybrid technique of management of a rare case of duodeno-duodenal intussusception.

We herein report a rare case of duodeno-duodenal intussusception (IS) presenting with obstruction caused by tubulovillous adenoma in an adult with malrotation that was managed by a novel laparoendoscopic hybrid technique. This was done by passing transjejunal nasogastric tube (NG) through one of the ports and manoeuvring it towards the IS. Two hundred and fifty millilitre of saline was flushed by aseptosyringe with pressure connected to the NG. This hydrostatic reduction technique resulted in distension of the jejunal and duodenal loop achieving reduction of IS. Intraoperative endoscopy was performed to exactly localise the mass lesion. The duodenum was kocherised and was delivered through a 4-cm transverse incision. Anterior duodenotomy was performed; the mass was excised; and duodenotomy was closed transversely. An extensive literature search did not show any case report of duodenoduodenal IS being managed by this technique. The combination of novel retrograde decompression and intraoperative endoscopy helped us to manage this rare case by this novel technique.

Management of intussusception in children: A comparative study of hydrostatic reduction with saline under ultrasound guidance versus laparoscopic assistance.

Introduction: Intussusception is a common cause of intestinal obstruction in infants and children. Ultrasound-guided hydrostatic reduction (USGHR) with saline is considered the gold standard with a success rate of more than 90%. Hydrostatic reduction with laparoscopic assistance has its own advantage of direct visualisation, assessment of bowel vascularity and controlled distension. The choice of procedure depends on available resources and surgeon's preference. This study aims to compare the outcomes of the two methods, i.e., laparoscopic-assisted hydrostatic reduction (LAHR) and USGHR under general anaesthesia (GA). Materials and Methods: This was a prospective study carried out at two different centres over a 3-year period. All patients of intussusception were managed by either hydrostatic reduction with saline under ultrasound guidance or hydrostatic reduction with laparoscopic assistance. Both the procedures were done in operation theatre under GA. The operating time and amount of fluid used for reduction were noted. Results: There were 27 patients in Group 1 (USGHR) and 20 patients in Group 2 (LAHR). The two groups were similar in terms of demographic parameters. The various outcomes such as number of attempts for reduction, fluid required for reduction, time to start oral feeds, complication and length of stay were similar in both the groups. The mean operating time for Group 1 was 19.4 ± 4.5 min and for Group 2 was 34.9 ± 4.8 min (P < 0.001). Conclusion: Both the procedures fare equally in terms of outcome except mean operating time, therefore, LAHR is a good alternative to USGHR in resource-poor nations where logistics of intraoperative ultrasound may not be present.

Developing a nomogram for predicting surgical intervention in pediatric intussusception after hydrostatic reduction.

Purpose: The aim of this study was to develop and validate a nomogram for predicting surgical intervention in pediatric intussusception after hydrostatic reduction. Methods: Children with intussusception who had treated with sonographically guided saline hydrostatic reduction as an initial treatment were enrolled in this study. The enrolled patients were randomly selected for training and validation sets, and the split ratio was 7:3. The medical records of enrolled patients were retrospectively reviewed. The patients were divided into a surgery and a non-surgery group according to the results of the nonsurgical reduction. A model for predicting the risk of surgical treatment was virtualized by the nomogram using logistic regression analysis. Results: The training set consisted of 139 patients and the validation set included 74. After logistic regression analysis using training set, duration of symptoms, bloody stools, white blood cells (WBCs), creatine kinase isoenzyme (CK-MB), long-axis diameter, poor prognostic signs by ultrasound and mental state were identified as the independent predictors of surgical intervention for intussusception. A model that incorporated the above independent predictors was developed and presented as a nomogram. The C-index of the nomogram in the validation set was 0.948 (95% CI, 0.888-1.000). The calibration curve demonstrated a good agreement between prediction and observation. The decision curve analysis (DCA) curve showed that the model achieved a net benefit across all threshold probabilities. Conclusion: Based on the predictors of duration of symptoms, bloody stools, WBCs, CK-MB, long-axis diameter, poor prognostic signs by ultrasound and mental state, we developed a nomogram for predicting surgical intervention after hydrostatic reduction. This nomogram could be applied directly to facilitate pre-surgery decision for pediatric intussusception.

Ultrasound guided hydrostatic enema reduction of ileocolic intussusception: a safe and effective technique.

BACKGROUND: Currently, the primary management of ileocolic intussusception in children is usually by non-operative image-guided enema reduction. In most centres around the world especially in Australasia the predominant technique is the pneumatic reduction under fluoroscopic guidance. At our institution, we have been performing ultrasound-guided hydrostatic reduction since 2012.This is an audit to determine the efficacy and safety of ultrasound-guided hydrostatic reduction for intussusception. METHODS: Following ethics approval, a retrospective review of all patients presenting to our institution with intussusception and subsequently undergoing hydrostatic reduction over a period of 9 years (2012 to-2020) was performed. The parameters studied included (i) successful reduction, (ii) recurrence, (iii) need for surgery and (iv) lead point at surgery. RESULTS: The mean age at presentation was 12 months. One hundred and eight children were diagnosed to have ileocolic intussusception. One hundred and six underwent ultrasound-guided hydrostatic reduction with successful reduction in 96 (90.5%) patients. Reduction was unsuccessful in 10 patients (9.5%). Of these eight were noted to have a pathological lead point (four-Meckel's diverticulum and four-Lymphoma) at the time of the surgery. The intussusception recurred in six patients (6.25%) within 24 h. No reduction related perforation occurred during the study period. CONCLUSION: Ultrasound-guided hydrostatic reduction is a safe and effective technique for managing intussusception as it allows continuous monitoring of the reduction of the intussusception without exposing the children to ionizing radiation.

Ultrasound-guided reduction of intussusception in infants in a developing world: saline hydrostatic or pneumatic technique?

Non-operative reduction has emerged as first line in the management of uncomplicated intussusception. The aim of this study was to compare the outcome of ultrasound-guided saline hydrostatic reduction and ultrasound-guided pneumatic reduction of intussusception in infants. This is a prospective study of infants with uncomplicated intussusception confirmed by ultrasound over a period of 21 months from December 2018 to August 2020. Fifty-two (69.3%) out of seventy-five infants were eligible and randomized based on simple random sampling technique into two groups: Group A included patients who had ultrasound-guided hydrostatic (saline) reduction; Group B included patients who had ultrasound-guided pneumatic (air) reduction. The success rates, time to reduction and complication rates were assessed. The success rates, between the saline hydrostatic reduction group and pneumatic reduction group, were comparable [17 (65.4%) versus 19 (73.1%); relative risk (RR) 0.8; 95% confidence interval (CI) 0.6-1.2; p = 0.54]. The mean time to reduction was higher in the saline hydrostatic reduction group (15.4 ± 5.1 min versus 10.8 ± 4.1 min; p = 0.003). There was no statistically significant difference in the perforation and recurrence rates between the two groups. CONCLUSION: Saline hydrostatic reduction and pneumatic reduction of uncomplicated intussusception under ultrasound guidance in infants might have comparable outcomes. However, pneumatic reduction may be faster. WHAT IS KNOWN: • Ileocolic intussusception is the most common cause of intestinal obstruction in infants. • Ultrasonography is useful in the diagnosis and non-operative treatment of ileocolic intussusception. WHAT IS NEW: • Ultrasound-guided hydrostatic enema and ultrasound-guided pneumatic enema are similarly effective and safe techniques in the reduction of ileocolic intussusception. • Reduction of ileocolic intussusception under ultrasound guidance is a great technique that may prove useful in the developing world due to lower cost of required equipment.

The Syringe Technique for Ultrasound-Guided Hydrostatic Intussusception Reduction.

Background: Ultrasound-guided hydrostatic reduction (UGHR) is a well accepted and widely used method of paediatric intussusception reduction, with the saline drip technique being the most commonly employed. Aims and Objectives: In this study we aimed to assess the outcomes of a novel technique of UGHR. Materials and Methods: Data was obtained from a 15 year retrospective chart review of paediatric intussusceptions. Following resuscitation, UGHR was performed for uncomplicated intussusceptions using a 50cc syringe to infuse saline into the colon. It was performed in the ultrasound suite without sedation and time taken was monitored. A maximum of 3 attempts were done to achieve reduction. Results: UGHR was attempted in 66 of 93 intussusceptions. The commonest type of intussusception was ileo-colic(91%) and the commonest symptom was vomiting(70%). Surgery was performed only when there was shock, peritonitis or repeated failed reductions. The median time taken for reduction was 4.9 minutes. The overall success rate was 83% with 89% of these requiring only a single attempt. There were no deaths or procedure related complications. Conclusions: The syringe technique for intussusception reduction is a safe, effective, and time-saving technique. Additionally, it offers the advantages of simplicity and rapidity of reduction and in experienced hands may not require pressure monitoring.

Risk factors for recurrent intussusception after successful reduction in pediatric patients in a tertiary care hospital of Nepal: A prospective study.

Background: Intussusception is defined as the invagination of one segment of intestine into another segment of intestine. It may recur because of persistence or return of some factor responsible for the primary intussusception. Various risk factors have been reported but still not well elucidated. Materials and methods: This is the prospective observational study. In this study, 78 patients, age <16 years with diagnosis of intussusception between June 2019 and April 2020 who had successful reduction with either hydrostatic reduction and/or operative reduction in Teaching Hospital were enrolled in the study. This is study of early recurrence as patients were followed up to a period of 1 month for recurrence of intussusception. The recurrent cases were thus identified and various variables were compared between recurrent and non-recurrent cases by univariable and multivariable analysis. Results: Among 78 patients, 13 patients (16.7%) had recurrent intussusception. In the univariable analysis model, the significant risk factors for recurrence of intussusception analyzed were duration of symptoms of 48 h or more, fever, blood in stool and palpable mass. While after multivariable analysis, we found that the significant risk factors for recurrence of intussusception were duration of symptoms ≥48 h (OR = 5.32, p-value = 0.047), Fever (OR = 17.32, p-value = 0.001), palpable mass (OR = 24.12, p-value = 0.017). Conclusion: Attention and awareness among pediatricians about these sonographic and clinical risk factors especially symptoms for recurrence are needed to minimize pre-hospital delay and identify patients in risk of recurrence. This ultimately helps to improve care for pediatric patients with recurrent intussusception.

Prediction of Outcomes of Ultrasound-Guided Saline Enema in the Treatment of Pediatric Intussusception: A Retrospective Case-Control Study.

OBJECTIVES: Outcomes of ultrasound-guided saline enema include successful treatment, unsuccessful treatment, or recurrence. This study aimed to investigate the value of ultrasonic parameters of the ileocecal region during hydrostatic reduction to predict enema outcomes. METHODS: Ultrasound images of patients diagnosed with ileocolic intussusception and treated with ultrasound-guided saline enema at two different institutions between January 2019 and April 2021 were retrospectively analyzed to assess ileocecal-valve diameter (ICVD), intussusceptum thickness (IT), and the ratio of IT to ICVD (I/I). Logistic regression analysis was used to explore correlations between ICVD, IT, I/I, and patient characteristics (sex, age, symptom duration, and enema outcome). RESULTS: Of 291 patients with ileocolic intussusception (207 boys; mean ICVD, 8.6 [SD: 0.1] mm; mean IT, 26 [SD: 0.2] mm; mean I/I, 3.0 [SD: 0.01]), 268 had first successful reduction; 23, first failed reduction; 7, final failed reduction; and 41, early recurrence. Significant risk factors for failed reduction included symptom duration >24 hours (odds ratio [OR] = 10, P = .012), ICVD ≤ 8.5 mm (OR = 8, P = .01), and I/I > 3.25 (OR = 16, P < .001). Significant risk factors for early recurrence post-enema included age >1 year (OR = 10, P = .028), ICVD > 8.5 mm (OR = 4, P = .003), and I/I ≤ 2.95 (OR = 6, P < .001). CONCLUSIONS: ICVD and IT measured during ultrasound-guided hydrostatic reduction can predict enema outcomes. The mismatch between IT and ICVD is the primary cause of poor outcomes.

Ultrasound-guided hydrostatic reduction of ileo-colic intussusception in childhood: first-line management for both primary and recurrent cases.

OBJECTIVE: To evaluate the results of ultrasonography-guided hydrostatic reduction in primary and recurrent ileo-colic intussusception in children. METHODS: The children (<18 years of age) who were managed for ileo-colic intussusception between January 2015 and December 2018 were evaluated retrospectively. Age, gender, presenting complaints, length of the intussuscepted segment, presence of lead point, treatment modalities, recurrence rates and duration of recurrence were evaluated. RESULTS: 108 patients with ileo-colic intussusception were enrolled in the study; 59 were male and 49 were female with a mean age of 2.04 ± 1.71 years. Two patients underwent immediate surgery without any attempt of hydrostatic reduction. Nineteen patients (18%) were managed by conservative measures initially. Seventeen (89.5%) of them have recovered with expectant management and two patients required hydrostatic enema reduction during follow-up. In total, 89 patients underwent hydrostatic reduction; 48 were male and 41were female with a mean age of 1.9 ± 1.65 years. Twelve patients (13.5%) received surgery after failed hydrostatic reduction. In the patients with successful hydrostatic reduction, one more episode of intussusception is seen in 10 patients (13%) and 2 additional episodes in 2 (2.6%). Seven patients with relapse were male and 5 were female with a mean age of 1.16 ± 1.64 years. The median duration of the first relapse episode was 67.5 days (range 18-110 days). The ultrasound-guided hydrostatic reduction was also successful in patients with recurrence. CONCLUSION: Ultrasound-guided hydrostatic reduction is a non-invasive treatment of ileo-colic intussusception with high success rates in childhood. It can be performed safely in both initial and relapse episodes of intussusception.

Shear wave elastography evaluation in predicting the success of ultrasound-guided saline enema hydrostatic reduction technique in ileocolic intussusception.

BACKGROUND: Intussusception is the invagination of the proximal intestinal segment into the distal portion. Reduction procedures with fluid or air have been used as the primary treatment of choice in clinically stable children. PURPOSE: To evaluate the role of intestinal wall elasticity measurements by shear wave elastography (SWE) to predict the success of ultrasound-guided saline enema (USGSE) reduction. METHODS: USGSE was performed, if not contraindicated otherwise, after the diagnosis of ileocecal intussusception via the ultrasound (US). The length and diameter of the intussusception and the median stiffness of the intestine were measured before USGSE. RESULTS: Seventeen children were diagnosed with ileocolic intussusception via grayscale US assessment. Two children whose SWE images became artifacts due to inadaptability were excluded from the study. Thus, the study involved 15 patients (9 boys, 6 girls; age range = 11-48 months). There was no statistically significant association between age and median stiffness measurement in kilopascal (kPa). (P > 0.05). A moderate positive correlation was observed between the median stiffness measurement (kPa) and the length of intussusception (r = 0.547; P = 0.035). There was no statistically significant relationship between median stiffness measurement (kPa) and short-axis diameter of intussusception (P > 0.05). CONCLUSIONS: Stiffness assessment of the intestinal wall in ileocolic intussusception during the US examination, which is the gold standard in the intussusception assessment, can be used as a new criterion for predicting the performance of the USGSE technique and might be useful in making decisions regarding the clinical management of ileocolic intussusception.

A Technique to Reduce the Early Recurrence of Intussusception in Ultrasound-Guided Hydrostatic Reduction.

OBJECTIVES: Ultrasound-guided saline enema is highly successful in treating pediatric intussusception; however, early recurrence-within 48 hours-is possible. This study aimed to explore effective methods of reducing early recurrence. METHODS: This study included patients aged 0 to 14 years diagnosed with ileocolic intussusception with a symptom duration of <48 hours from January 2019 to March 2021. The patients were divided into control and intervention groups. All patients received successful treatment with ultrasound-guided saline enema; however, in patients treated before January 4, 2020 (control group), the intestinal fluid was drained immediately, and in patients treated after January 4, 2020 (intervention group), the intestinal fluid was drained after 15 minutes of intestinal pressure maintenance. Early recurrence rates of the groups were compared. RESULTS: Ileocolic intussusception was treated successfully by ultrasound-guided saline enema in 231 patients (116, control group;115, intervention group). The early recurrence rate in the intervention group (10%; 95% CI: 4.9-16.5) was numerically lower than that in the control group (19%; 95% CI: 12.3-27.3). No significant difference was observed in the number of recurrences per person between the groups (P = .448). Patients without early recurrence were older (P = .004) and received enemas of a shorter duration (P < .001) and lower pressure (P < .001) than patients without early recurrence. CONCLUSIONS: Maintaining reduction pressure for 15 minutes after a successful ultrasound-guided saline enema may reduce the early recurrence of intussusception. A randomized controlled trial is needed because the intervention and control cohorts were most probably incomparable (due to the COVID-19 pandemic).

Factors Associated with a Failed Nonoperative Reduction of Intussusception in Children.

AIMS: The aim of this study was to evaluate the factors associated with the failure of nonoperative reduction of intussusception in children. METHODS: A retrospective study was conducted in a tertiary care pediatric surgery hospital. The children admitted to the department of pediatric surgery between November 2013 and February 2020 with the diagnosis of Intussusception were included. RESULTS: A total of 106 (67%) children underwent pneumatic reduction. Eighty-nine (84%) children had a successful reduction. A higher rate of failed reduction was found in children who presented at or after 48 h of the onset of symptoms (P = 0.03) and abdominal distension at presentation (P < 0.002). On multiple logistic regression analysis, the children presenting at or after 48 h of the onset of symptoms (odds ratio [OR] = 11.3; P = 0.039) and abdominal distension at presentation (OR = 4.46; P = 0.021) were found to be associated with increased risk of failure of nonoperative reduction. The variables age <1 year, weight <10 kg, pain abdomen, vomiting, bilious vomiting, fever, bleeding per rectum, and palpable mass were not associated with the failed nonoperative reduction. The variables, presentation at or after 48 h of the onset of symptoms (OR = 2.812; P = 0.045) and abdominal distension at presentation (OR = 8.758; P = 0.000) were found to be associated with an increased need for surgery. CONCLUSION: The risk factors for failed nonoperative reduction of intussusception include a presentation at or after 48 h of the onset of symptoms and the presence of abdominal distension at presentation. The delayed presentation was associated with the increased need for surgery and increased chances of intestinal nonviability.

Effectiveness and safety of ultrasound-guided hydrostatic reduction for children with acute intussusception.

OBJECTIVE: This study aims to explore the effectiveness and safety of the new-type ultrasound-guided hydrostatic reduction for children with acute intussusception. METHODS: The clinical data of 364 children with primary acute intussusception who underwent nonsurgical reduction in our hospital between January 2016 and May 2019 were retrospectively analyzed. Among the 364 children, 119 formed the hydrostatic reduction group. There were 89 males and 30 females, and the average age of admission was 25.13 ± 1.43 months. Among the pneumatic reduction group of 245 patients, there were 163 males and 82 females. The average age of admission was 22.47 ± 1.52 months. The reduction rate, length of stay, and perforation rate were compared between the two groups. RESULTS: Univariate analysis showed that the reduction rate in the hydrostatic group (94.96%) was higher than in the pneumatic group (85.31%) (p = 0.007), and the hospital stay (2.76 ± 0.15 days) of the hydrostatic reduction group was shorter than that of the pneumatic reduction group (3.56 ± 0.35 days) (p = 0.038). In children with intussusception time >48 h, the reduction rate was 95.45% in the hydrostatic reduction group and 86.20% in the pneumatic reduction group. CONCLUSION: The new-type ultrasound-guided hydrostatic reduction has a higher reduction rate in the treatment of acute intussusception in children results in a shortened hospital stay, It is effective, safe, and avoids radiation exposure.

Intussusception in children under five years of age in Enugu, Nigeria.

INTRODUCTION: intussusception is the invagination of a segment of the bowel into a distal segment. It occurs predominantly in infants worldwide. Following documentation of increased incidence after introduction of the first rotavirus vaccine (Rotashield, Wyeth-Lederle), it has become a standard recommendation to maintain surveillance for intussusception as newer rotavirus vaccines are introduced into EPI. Nigeria plans to introduce rotavirus vaccine in 2020. Pre-vaccine introduction surveillance will serve as a baseline to understand the epidemiology of intussusception in Nigeria. METHODS: from 2013 to 2017, prospective enrolment of under five children with intussusception was done following the WHO protocol and using the WHO case report form. Only children who met the Pan American Health Organization/World Health Organization (PAHO/WHO) protocol case definition for intussusception were enrolled. These children were monitored until discharge or death. Clinical features and outcome were recorded in the case report form. RESULTS: a total of 63 cases were enrolled, with age range of 3 to 42 months (median: 6 months, IQR: 5-9 months). Majority were within 4-6 months and 96% were < 12 months old. There were 41 males and 22 females (male to female ratio of 1.9:1). Duration of symptoms before presentation ranged from 2 hours to 15 days (median: 72 hours). Fifty-seven patients had abdominal ultrasound and 52 patients (83%) had surgery. Case fatality rate was 9% and duration of hospitalization ranged from 1 to 30 days (median 10 days, IQR 8-15 days). CONCLUSION: intussusception occurred most commonly in infants but well beyond the proposed age for rotavirus vaccination in the population studied. Late presentation and surgical intervention were common. This data provides a good baseline description of the epidemiology of intussusception.

Nonsurgical reduction of prolapsed colocolic intussusception in 2 puppies.

OBJECTIVE: To describe the nonsurgical management of prolapsed colocolic intussusception in 2 puppies. CASE SUMMARY: Two 3-month-old male intact puppies (Pug and Labrador Retriever) developed intussusceptions that had prolapsed from the anus after they had suffered from tenesmus with soft feces or diarrhea. Reduction of the prolapsed tissue was performed and colocolic intussusception was diagnosed ultrasonographically in 1 dog. Rectal manipulation and saline enema were performed in both dogs, and reduction of the intussusception was confirmed endoscopically or ultrasonographically. Bupivacaine and prednisolone foam enemas were administered to reduce tenesmus. Abdominal ultrasonography the following day in 1 dog confirmed a normal appearing colon. No further tenesmus was noted in 1 dog; the other had a brief rectal prolapse after an episode of tenesmus that was manually reduced. Intussusception had not recurred 4 months and 1 year following manual reduction procedures. NEW OR UNIQUE INFORMATION PROVIDED: This is the first report of successful nonsurgical management of colocolic intussusception in a companion animal. Nonsurgical management is a first-line treatment of intussusception in children and could be considered in dogs with colocolic intussusception. Further investigation is required to define specific aspects, including rectal manipulation, saline enema, or anesthesia, that aid in resolution of this type of intussusception.

Guía de Práctica Clínica de invaginación intestinal en niños / Clinical Practice Guideline Intestinal invagination in children

La invaginación intestinal es la causa de oclusión intestinal más frecuente en los lactantes y niños menores de dos años. Por su frecuencia, la diversidad de formas clínicas y las variantes de tratamiento disponibles se confecciona esta guía, con el objetivo de lograr el diagnóstico temprano en el mayor número de casos y sistematizar el tratamiento actualizado de esta entidad en los servicios de cirugía pediátrica. La forma de presentación clásica: cólicos, vómitos, deposiciones en jalea de grosella y letargo, solo está presente en el 30 por ciento de los pacientes. Actualmente el diagnóstico se confirma por ecografía. La invaginación puede ser tratada de dos formas: por métodos de reducción hidrostática o neumática con seguimiento por imágenes, indicada en los niños con invaginaciones no complicadas, y tratamiento quirúrgico. Se presenta la Guía de Práctica Clínica de Invaginación intestinal aprobada por consenso en el III Simposio Nacional de Cirugía Pediátrica en Varadero/2019(AU)

Intestinal invagination is the most common cause of intestinal occlusion in infants and children under two years of age. Due to its frequency, the diversity of clinical forms and the available treatment variants, this Guideline is made with the aim of achieving early diagnosis in the greatest number of cases and systematizing the updated treatment of this entity in pediatric surgery services. The classic presentation form of it is: colics, vomiting, gooseberry jelly kind of stools and lethargy, only present in 30 percent of patients. Diagnosis is currently confirmed by ultrasound. Invagination can be treated in two ways: by hydrostatic or pneumatic reduction methods with imaging follow-up, indicated in children with non-complicated invaginations, and surgical treatment. The Clinical Practice Guideline for Intestinal Invagination approved by consensus was presented at the III National Symposium of Pediatric Surgery in Varadero/2019(AU)

Ultrasonography-guided hydrostatic reduction of ileocolic intussusception in childhood: First-line option for management of primary and recurrent cases.

OBJECTIVE: To evaluate the results of ultrasonography-guided hydrostatic reduction in primary and recurrent ileo-colic intussusception in children. METHODS: The children (<18 years of age) who were managed for ileocolic intussusception between January 2015 and December 2018 were evaluated retrospectively. Age, gender, presenting complaints, length of the intussuscepted segment, presence of leading point, treatment modalities, recurrence rates and duration of recurrence were evaluated. RESULTS: 108 patients with ileocolic intussusception were enrolled in the study; 59 were male and 49 were female with a mean age of 2.04 ± 1.71 years. Two patients underwent immediate surgery without any attempt of hydrostatic reduction. Nineteen patients (18%) were managed by conservative measures initially. Seventeen (89.5%) of them have recovered with expectant management and two patients required hydrostatic enema reduction during follow-up. In total, 89 patients underwent hydrostatic reduction; 48 were male and 41were female with a mean age of 1.9 ± 1.65 years. Twelve patients (13.5%) received surgery after failed hydrostatic reduction. In the patients with successful hydrostatic reduction, one more episode of intussusception is seen in 10 patients (13%) and 2 additional episodes in 2 (2.6%). Seven patients with relapse were male and 5 were female with a mean age of 1.16 ± 1.64 years. The median duration of the first relapse episode was 67.5 days (range;18-110 days). The ultrasound-guided hydrostatic reduction was also successful in patients with recurrence. CONCLUSION: Ultrasound-guided hydrostatic reduction is a non-invasive treatment of ileocolic intussusception with high success rates in childhood. It can be performed safely in both initial and relapse episodes of intussusception.

The effectiveness and safety of ultrasound-guided hydrostatic reduction for pediatric acute intussusception / 中华超声影像学杂志

Objective:To evaluate the effectiveness and safety of ultrasound-guided hydrostatic reduction for pediatric acute intussusception.Methods:One thousand eight hundred and thirty patients with acute intussusception diagnosed by ultrasound in Shenzhen Children′s Hospital from September 2017 to July 2020 were treated with ultrasound-guided hydrostatic reduction method. The therapeutic effects, complications and ultrasonic features were observed.Results:Among 1 830 cases, 1 791 cases were diagnosed as primary intussusception, and 39 cases were secondary intussusception. The overall rate of successful ultrasound enema reduction were 1 780/1 830(93.7%) patients. All 50/1 830(2.7%) patients underwent surgery after unsuccessful enema reduction, including 42 cases of primary intussusception, and 8 cases of secondary intussusception. The complication of intestinal perforation occurred in 3 cases (0.16%), and there were no deaths.Conclusions:Ultrasound-guided enema reduction for pediatric acute intussusception is an effective and safe method without radiation exposure, and can be used as the preferred method for non-operative treatment of intussusception.
