Surgical management of intertumor abscesses caused by fistulous communications with the intestine: rare complication in pediatric malignant tumor: 2 case reports

Abstract

Rationale: Unresectable abdominal tumors cause various complications, and fi stulizaton with intestine is a rare but serious complication. We report this condition in 2 cases. Patient Concerns: The fi rst case was that of a 14-year-old male patient who had a desmoid tumor and the second case was that of a 17-year-old female patient with a recurrent malignant peripheral nerve sheath tumor. They were admitted with a giant chemo-resistant tumor that was gradually growing and causing abdominal pain. Diagnoses: They were diagnosed with intertumor abscesses caused by fi stulous communications with the intestine. Interventions: Both the patients underwent percutaneous drainage, and after being stabilized, they underwent surgery. Outcomes: The patient with desmoid tumor was continuing his daily routine without any problem. The patient with malignant peripheral nerve sheath tumor was able to consume food orally and discharged after the surgery. Lessons: In the treatment of abdominal intratumor abscesses caused by fi stulous communications with intestine, it is necessary to consider the optimal treatment strategies based on the tumor location and patient prognosis.
