RESUMEN

BACKGROUND: Intestinal intussusception is the most common cause of intestinal obstruction in infants and children under 3 years of age. Any delay in diagnosis or management can lead to intestinal ischaemia and perforation. The aim of this study is to determine the sociodemographic and clinical risk factors associated with bowel resection in infants and children with intussusception. MATERIALS AND METHODS: This is a retrospective analytical study of 118 patients operated at the Hassan II Hospital and University of Fez between 1 January 2008 and 1 January 2018. A comparison of risk factors between patients with and without bowel resection was performed using multivariate logistic regression. RESULTS: One hundred and eighteen patients met the inclusion criteria. Of these, 44% had undergone bowel resection. Age >2 years (P = 0.006), duration of symptoms progression of more than 2 days (P = 0.002), bilious vomiting (P = 0.04) and palpation of an abdominal mass (P = 0.01) were significantly associated with bowel resection. Multivariate logistic regression showed that age <2 years (odds ratio [OR] =4.47 95% confidence interval [CI]: 1.12-17.78) and duration of symptom progression of more than 2 days (OR = 2.62 95% CI: 1.12-6.11) were independent risk factors for bowel resection. CONCLUSION: Intussusception that occurs in child old than 2 years of age, or which has progressed for more than 2 days, is associated with an increased risk of intestinal resection.

RESUMEN

The incidence of jejunogastric intussusception (JGI) after gastric surgery is 0.1%. We report a case of JGI after pancreaticoduodenectomy in a patient with HIV. After presenting to the hospital with abdominal pain and emesis, a CT abdomen/pelvis showed evidence of gastrojejunal anastomosis intussusception into the stomach. Oesophagogastroduodenoscopy was performed, but endoscopic reduction was unsuccessful. Exploratory laparotomy was subsequently performed with a successful reduction of the intussusception and resection of a portion of the small bowel. With only five previously reported cases of JGI after pancreaticoduodenectomy, our case is novel in that it describes JGI in a patient with HIV on highly active antiretroviral therapy, which has been associated with an increased risk of intussusception. While rare, we highlight the importance of having high clinical suspicion for intussusception in patients with risk factors who present with abdominal pain after pancreaticoduodenectomy. Timely diagnosis is critical to optimise patient outcomes.

RESUMEN

INTRODUCTION: Intussusception is a prevalent paediatric emergency condition. The standard of care involves the reduction using air or fluid enema is considered a safe procedure. Sedation-induced muscle relaxation thus optimising the treatment. We present a comprehensive 6- year study involving non sedative reduction (NSR) versus sedative reduction (SR) utilising ketamine and midazolam. MATERIALS AND METHODS: A retrospective cohort study was conducted between January 2017 and July 2023 in Yogyakarta, Indonesia. A total of 85 children diagnosed with intussusception underwent hydrostatic reduction, which employed water-soluble contrast administered into the rectum. Cases that were unsuccessful in reduction underwent immediate surgical intervention. RESULTS: Among the 85 children with intussusception underwent reduction, 22 children underwent the SR procedure and 63 underwent NSR procedure. We found a successful outcome in 17 cases (77%) of SR procedure with one recurrent and the other five (23%) got surgical reduction such as anastomosis resection (3 cases) due to Meckel- Diverticula. On the other hand, we found 24 successful cases (38.0%) in NSR procedure with one recurrent after case. 39 others who failed with NSR continued to surgical reduction. Manual reduction was done for 31 patients with one case mortality due to pulmonary bleeding. Anastomosis resection (4 cases) and, stoma (4 cases) were decided for others surgical reduction. The relative risk (RR) on this study was 2.02 (p value < 0.05, CI 95%). CONCLUSION: Implementation of the SR procedure may reduce surgery rates in paediatric intussusception, thereby enhancing patient management. Furthermore, the success rate of hydrostatic reduction higher in under sedation procedure. We contribute to evolve insight of non-operative approaches of paediatric intussusception management, particularly in the Yogyakarta.

RESUMEN

Intussusception is rare in adults, making it a challenging and often delayed diagnosis. Patients may re-present with non-specific and subacute abdominal symptoms. Abdominal CT is the most sensitive imaging modality and is often required to make the diagnosis of intussusception. In contrast to the paediatric population, intussusception in adults is most often associated with a pathological lesion acting as a lead point. In adults, the lead point is often secondary to malignancy, though benign lesions can also be implicated. As such, surgical management with selective resection is the mainstay of treatment in adults. We describe a rare case of ileocaecal intussusception in an adult secondary to a large ileocaecal lipoma, successfully treated with laparotomy and resection in a remote Western Australian hospital. The increasing availability of CT imaging and skilled general surgeons in rural and remote Australia allows for the diagnosis and surgical management of such cases without inter-hospital transfer.

RESUMEN

BACKGROUND: Intussusception with intestinal malrotation is termed as Waugh's syndrome. The incidence of Waugh's syndrome is less than 1%. There are very few reported cases. Once presented, it is a pediatric surgical emergency. CASE PRESENTATION: We present here two cases of Waugh's syndrome: an 11-month-old male patient of Punjabi descent and a 4-month-old female patient of Afghan descent who presented to us with abdominal pain and bleeding per rectum. Abdominal sonography revealed an intussusception with a target sign. They were explored and perioperatively had intestinal malrotation alongside intussusception, thus a diagnosis of Waugh's syndrome was made. A right hemicolectomy and Ladd's procedure was performed. CONCLUSION: Waugh syndrome is a rare congenital anomaly but can present with vague abdominal symptoms. Once presented, it is a pediatric surgical emergency. The patient should be optimized followed by surgical exploration.

RESUMEN

We report the case of ileo-ileal intussusception secondary to a Peutz-Jeghers syndrome (PJS) hamartomatous polyp in a male infant. The patient presented with non-bilious vomiting and a single episode of passing blood in his stool. An upper gastrointestinal contrast study showed proximal bowel obstruction. At laparotomy, ileo-ileal intussusception was identified with a papillary mass acting as a lead point. The mass was resected, and a primary anastomosis was performed. The patient recovered well and was discharged on postoperative day 5. Histological assessment diagnosed a PJS hamartoma. The patient was well at 1 month follow-up. This case report describes a rare cause of intussusception in an infant that should be considered in the differential diagnosis. The diagnosis of PJS in infancy is uncommon and requires long-term follow-up.

RESUMEN

BACKGROUND: Intussusception in adults is a rare condition characterized by a low incidence, which complicates the establishment of standardized management protocols unlike those readily available for pediatric cases. This study presents a case series from our institution alongside a systematic review of existing literature. The objective is to delineate effective management strategies for adult intussusception. METHODS: A systematic search of databases was conducted covering the period from January 2000 to May 2024. The study focused on adult patients diagnosed with intussusception either pre-operatively or intraoperatively and managed with either surgical intervention or conservative methods. The analysis also included retrospective review of patient records from our institution, specifically targeting individuals over 18 years of age, to determine the predominant types of intussusception and identify any pathological lead points associated with these cases. RESULTS: In our study, a total of 1,902 patients were included from 59 selected articles, with a mean age of 52.13 ± 14.95 years. Among them, 1,920 intussusceptions were diagnosed, with 98.3% of cases identified preoperatively. Computed tomography (CT) scan was the primary diagnostic modality used in 88.5% of cases. Abdominal pain was the predominant presenting symptom, observed in 86.23% of cases. Only 29 out of 1,920 cases underwent attempted reduction, while the majority required surgical resection due to the high incidence of malignancy in adult cases. The most common type of intussusception identified was colocolic (16.82%), followed by enteric (13.28%), ileocolic (4.89%), and ileocaecal (0.78%) types. A pathological lead point was observed in 302 out of 673 patients (44.84%), with a notably higher frequency of malignancy associated with colocolic intussusception. CONCLUSION: Surgical management remains the cornerstone in treating adult intussusception, particularly in cases involving the colocolic type, where there is a significant risk of underlying malignancy. Attempts at reduction are generally avoided due to the potential risk of tumor dissemination, which could adversely impact patient outcomes. Contrast-enhanced computed tomography (CECT) of the abdomen is pivotal for accurately diagnosing intussusceptions and guiding appropriate management strategies. It is imperative to adhere strictly to oncological principles during surgical interventions to ensure optimal patient care and outcomes.

RESUMEN

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.

RESUMEN

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.

RESUMEN

A colonic lipoma is an uncommon lesion that is linked with clinical symptoms in only a small portion of patients. Patients with large lipomas are often referred for major surgery, which is associated with significant morbidity and mortality. In this case, we described a female patient with recurrent episodes of gastrointestinal blood loss, abdominal pain and colocolic intussusceptions due to a large, lumen-filling, obstructive lipoma in the splenic flexure. On abdominal CT, a lesion of 3.6 cm was visualised with a fat-like density without solid components. Considering its benign nature, we intended to preserve the colon by deroofing the upper part of the lesion and then performing a colonoscopy-assisted laparoscopic wedge resection. During reassessment, auto-amputation of part of the lesion was observed, most likely as a result of long-lasting mechanical effects, which made it possible to perform solely a wedge resection with an excellent outcome.

RESUMEN

Intussusception is defined as the invagination of a proximal segment of the bowel into the adjoining or distal segment. In most adults with intussusception, there is a demonstrable lead point with a definite pathologic abnormality. The clinical features of intussusception include chronic intermittent abdominal pain, nausea and vomiting, constipation, and a palpable abdominal mass. The present case report describes a 62-year-old woman with a 2-week history of abdominal pain and 9-day history of vomiting. Clinical, imaging, and histologic evaluations revealed a jejunojejunal intussusception with a gastrointestinal stromal tumor as the lead point. A gastrointestinal stromal tumor should be considered as a possible lead point in adult patients with intussusception. The implication of reducing the intussusception prior to tumor resection requires further evaluation in view of the risk of venous embolism, including direct spread of malignant cells, in cases involving a large polypoid mass with a necrotic surface that extends to the serosa as shown by intraoperative examination. Accordingly, the rationale for adjuvant therapy with imatinib also requires further evaluation.

RESUMEN

RATIONALE: Retrograde jejunoduodenogastric intussusception refers to invagination of distal small intestine into the stomach. It is extremely rare. It is often associated with displaced feeding catheter in which its balloon tip migrates past the gastric pylorus. The intussusception is triggered by retraction of migrated catheter. It is often accompanied by feeding intolerance or catheter malfunction. This report describes a distinctive case of retrograde jejunoduodenogastric intussusception associated with a fully functioning nonballoon nasojejunal tube. PATIENT CONCERN: A 19-year-old female was presented with repeated vomiting and abdominal distension for 5 days. DIAGNOSIS: An abdominal computerized tomography revealed retrograde jejunoduodenogastric intussusception causing air/fluid-filled gastric distension. Immediate endoscopic examination revealed a loop of small intestine, protruding through the pylorus. Progressed ischemia of the migrated small bowel loop was confirmed. INTERVENTIONS: At laparotomy, a jejunal loop migrating into the duodenum and stomach at the level of the ligament of Treitz was noticed. After manual reduction of migrated bowel, 2 segmental resections of necrotic segment were performed. A feeding jejunostomy was constructed in the proximal jejunum. OUTCOMES: Enteral feeding through the surgically constructed feeding jejunostomy was started on the 5th operative day and the patient was discharged on the 16th postoperative day. LESSONS: When a patient under tube feeding exhibits abrupt intractable gastroesophageal reflux with a sign of catheter migration, we must consider the possibility of catheter-related intussusception. Having a fully functioning feeding catheter with nonballoon tip does not preclude retrograde jejunoduodenogastric intussusception.
