摘要
Background. Peristomal metastases are rare, but potentially associated with relevant morbidity. Surgical resection, followed by stoma relocation, represent the gold standard in most patients. We describe electrochemotherapy (ECT), a minimally invasive method for locally-enhancing drug delivery by means of electric pulses, as an alternative approach. %26lt;br%26gt;Patient and methods. A 49-year-old man with advanced gastric cancer developed skin metastases around an ileostomy site. The ulcerated and oozing tumor growth impaired patient%26apos;s quality of life due to continuous trouble in fitting the ostomy appliance, its poor adherence and consequent stools spillage. ECT consisted of a 20-minute course under mild general sedation. A bleomycin bolus of 15 000 IU/m(2) was followed by the percutaneous application of multiple, 1.5 ms -long electric pulses by means of a needle electrode. %26lt;br%26gt;Results. Post ECT course was uneventful and the patient was discharged on the same day. After one week, tumor nodules were flattened and partial tumor regression was appreciable at one-month follow-up. More importantly, peristomal skin conditions significantly improved, thus allowing for an effective application of the ostomy appliance during the following moths, until patient%26apos;s death. %26lt;br%26gt;Conclusions. This report suggests the feasibility of ECT as a minimally invasive approach for peristomal tumors. In selected cases, ECT, by achieving a rapid tumor control, may ensure effective ostomy management and preserve patients%26apos; quality of life.
