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.

Pneumatic reduction of intussusception: factors affecting outcome in Thailand.

Background: Pneumatic reduction has become a therapeutic method for intussusception instead of surgery. It is more successful than barium reduction, but it depends on how much the operator is familiar with the method and equipment. Objective: Determine success rate and recurrent rate of intussusception and factors affecting outcome of pneumatic reduction in Thailand. Materials and methods: Fifty-eight children with 73 numbers of intussusception who underwent pneumatic reduction at Songklanagarind Hospital, Thailand between January 2002 and March 2007 were retrospectively reviewed. Age, sex, clinical parameters, physical examination, imaging findings, and reduction technique were evaluated. Results: Overall success rate was 54 out of the 73 episodes and recurrent rate was 10 out of 58 patients with intussusception. Long duration of symptom, rectal bleeding, dehydration, and leukocytosis significantly affected poor outcome. Radiographic findings of gut obstruction and ascites as well as sonographic findings of thickened colonic wall, trapped fluid between intussusceptum and intussuscipien, and small bowel obstruction could also predict the poor outcome. Conclusion: Many factors from clinical presentation, plain radiographic, and sonographic findings affect poor outcome of pneumatic reduction. However, it can be performed unless peritonitis and sepsis/shock are present.

Comparison of Barium Reduction and Pneumatic Reduction of Intussusception in Children: A Surgeon's View

PURPOSE: Pneumatic reduction has rapidly replaced traditional barium reduction owing to its potential advantages, such as higher reduction rate and greater safety; however, the effects on surgery after reduction failure have not been studied. In this study, we evaluated the influences of attempted barium and pneumatic reductions on subsequent surgical procedures. METHODS: One hundred and sixty-one barium reductions were performed on 158 patients while 153 pneumatic reductions were performed on 145 patients. Statistical comparisons of these two reduction methods were made regarding the following variables: the reduction rates, frequencies of bowel perforations and recurrences, mean operation times, fasting periods, and durations of admission. RESULTS: The reduction rates were similar for both groups with barium reduction being successful in 67.1% of the cases (108/161) and pneumatic reduction in 69.3% (106/153). Two cases of bowel perforation occurred during the pneumatic reductions, none were noted during the barium reductions. Recurrence of intussusception was noted in three cases initially reduced with barium and in nine cases reduced pneumatically. The mean operation time (130.7 minutes vs. 81.7 minutes), postoperative fasting time (61.6 hours vs. 37.6 hours), and duration of admission (6.7 days vs. 5.4 days) were significantly prolonged in the pneumatic reduction group. CONCLUSION: A part from a comparable reduction rate pneumatic reduction demonstrated no favorable outcome relative to barium reduction. Furthermore, it resulted in some obstacles to surgery and recovery, such as prolonged operation time, fasting period, and duration of admission.
