Background and Purpose: Anatomical variations during prostate radiotherapy can cause discrepancies between planned and delivered doses, which may become more pronounced in (ultra-)hypofractionated regimens. However, a st...

BackgroundComplex anal fistulas remain a surgical challenge due to their intricate anatomy, high recurrence rates, and potential for sphincter injury. We report a rare case of complex anal fistula with multiple external ...

A 10-year-old patient was admitted to the pediatric sub-intensive care unit due to massive rectal bleeding and severe acute anemia. His medical background included Asperger syndrome and a history of chronic constipation ...

Background and purpose: Dose accumulation in reirradiation can contribute to both treatment outcomes and safe cumulative doses. We demonstrated consensus strategies on dose accumulation for three clinical reirradiation s...

Abstract Purpose Intraoperative radiotherapy (IORT) is designed to deliver a precise dose of ionizing radiation to a tumor or tumor bed after surgical resection. The IORT procedure can deliver targeted radiation to the t...

Purpose: To evaluate the impact of intra- and interfractional motion on dose distribution and clinical outcome in prostate magnetic resonance (MR)-guided adaptive radiotherapy. Methods: Seventy-six patients were treated ...

Introduction: Rectal atresia is a rare form of anorectal malformation characterized by a normally developed anal canal and sphincter complex; however, despite this favorable anatomy, the optimal surgical approach remains...

BackgroundComplex inflammatory phenotypes in children can pose significant diagnostic challenges, particularly when clinical, histopathologic, and immunologic findings do not conform to established diagnoses. We present ...
