Invaginación intestinal recurrente secundaria a apéndice cecal invaginado: caso clínico / Recurrent intussusception secondary to invaginated cecal appendix. Case report

Introducción: La invaginación intestinal es una patología de causa idiopática en el 95 por ciento de los casos, encontrándose en el 5 por ciento restante algún factor desencadenante que la justifique. Las recurrencias se presentan en un 7 a 12 por ciento de los casos y se asocian a múltiples causas. El objetivo de este trabajo es presentar el caso de un paciente con invaginación intestinal recurrente y analizar la causa de la recurrencia. Caso clínico: Paciente de 1 año y 4 meses de edad, sexo masculino, con antecedente de primer episodio de Invaginación intestinal operado a los 4 meses de edad. Presenta segundo episodio de invaginación a los 9 meses de edad, la cual se trató con desinvaginación neumática y a los 16 meses de edad presentó su tercer episodio, manejandose con desinvaginación hidrostática. Ocho horas post procedimiento el paciente presentó nueva invaginación; se realizó reducción manual quirúrgica. Se encontró una invaginación ileocólica con un remanente apendicular intracecal actuando como cabeza invaginante. Se reseco remanente y se envió a biopsia. Conclusiones: La invaginación intestinal recurrente se asocia a factores anatómicos desencadenantes, por lo cual al presentar recurrencias se debe tener en consideración una posible causa orgánica, ante lo cual se recomienda el tratamiento quirúrgico.

Introduction: Intussusception is an idiopathic pathology that accounts for 95 percent of cases found; the remaining 5 percent is caused by some triggering events. Recurrences occur in 7 to 12 percent of cases and are associated with multiple causes. The aim of this research is to present the case of a patient with recurrent intussusception and analyze the cause of the recurrence. Case report: The patient was a 16 month-old male infant with a history of first episode of intussusception surgery at 4 months old. His second intussusception episode took place at 9 months of age, which was treated with pneumatic reduction process; at 16 months of age he presented his third episode, which was treated with hydrostatic reduction process. 8 hours post procedure, the patient had a new intussusception condition and surgical manual reduction was performed. Ileocolic intussusception was found with an appendiceal intrathecal remnant acting as the invaginating head. Remnant was removed and sent for biopsy. Conclusions: Recurrent intussusception is associated with triggering anatomical factors; therefore, in the case of recurrences, a possible organic cause should be considered and surgical treatment is recommended.

Clinical Analysis of Recurrent Intussusception and the Pathologic Lead Point in a Single Center / 대한소아소화기영양학회지

PURPOSE: Intussusception is the most common cause of intestinal obstruction in young children. Although intussusceptions are easily treated, some intussusceptions with or without a pathologic lead point (PLP) often recur. In this study, we analyzed the clinical characteristics and prognosis of recurrent intussusceptions (RI), the frequency of the PLP, and correlation between RI with PLP. METHODS: The medical records of 144 patients, among 590 patients with intussusceptions who had been admitted to the Department of Pediatrics and Pediatric Surgery of Dankook University Hospital between May 1994 and June 2009 were reviewed retrospectively. RESULTS: The overall recurrence rate of intussusceptions in this study was 9.2%. The mean interval between the initial occurrence and the first recurrent attack was 130+/-175 days (range, 12 hours to 3 years). There was no statistically significant difference in the recurrence rate among patients who underwent air, barium, and manual reduction (p=0.131). Eighty-seven cases (92.6%) of RI had a successful reduction by the use of non-operative techniques. A PLP was present in 18 patients (3.0%). The most common PLP was intestinal lymphoid hyperplasia, followed by Meckel's diverticulum, duplication cyst, intestinal polyp, and adenomyoma. The mean number of intussusceptions was 4.7+/-1.9 in 7 patients with PLP, which was significantly higher than (2.4+/-0.9) patients without a PLP (p=0.023). The mean duration of recurrences was 17.4+/-19.8 months (range, 2 days to 72 months). CONCLUSION: A careful search for a PLP should be performed to prevent recurrence of intussusception, especially when intussusception has recurred more than three times.

Small Intestinal Mucosa Associated Lymphoid Tissue (MALT) Lymphoma in a Child Presenting with Recurrent Intussusception: A Case Report

Mucosa associated lymphoid tissue (MALT) lymphoma is a malignant B cell lymphoma that develops from MALT. The stomach is the most common site of MALT lymphomas but be found anywhere in the body. Adult MALT lymphomas are not rare diseases, but in children, intestinal MALT lymphomas are very rare. We treated a 12-year-old boy who underwent segmental resection of the small intestine due to recurrent intussusceptions, 2 months apart, and was diagnosed with an intestinal MALT lymphoma. He received multiple chemotherapeutic agents (vincristin, cyclophosphamide, prednisone, methotrexate, doxorubicin and cytosine arabinoside) according to the CCG-5961 protocol for 3 months. Currently, he is alive and disease free.

A Case of Recurrent Transient Small Bowel Intussusception / 대한소아소화기영양학회지

Isolated small bowel intussusception accounts for 10% of all pediatric intussusception. It is more common in children older than 2 years of age. Presentation usually is with vomiting and abdominal pain. Currant jelly stool and palpable mass are less frequent than typical intussusception. There are few reported cases of children with transient small bowel intussusception. We describe 3-year-old boy presented with intermittent cyclic crampy abdominal pain for 6 months was diagnosed as having recurrent transient small bowel intussusception by abdominal ultrasonography and small bowel series.
