RESUMO

Angiosarcomas are rare tumors that usually entail a poor prognosis because of extensive invasiveness and high rates of distant metastasis. Gastrointestinal tract involvement is uncommon but may cause digestive bleeding. A definitive diagnosis requires histological and immunohistochemical testing. Metastatic lesions to the gut usually have a typical morphology, which must be identified in order to avoid delay in the diagnosis and potential treatment of this malignant condition.

RESUMO

BACKGROUND: Anastomotic dehiscence is a common complication of anterior resection. In this work, we evaluate the management of the pelvic cavity after low rectal resection using vacuum closure (VAC) with a gastroscope, and we establish factors that determine the success of closure and analyzed the rate of ileostomy closure after leakage was resolved. PATIENTS AND METHODS: This is a descriptive case series analysis conducted at a tertiary hospital. Twenty-two patients with low colorectal anastomosis leakage or opening of the rectal stump after anterior resection for rectal cancer were included. They were treated with VAC therapy. RESULTS: The total number of endoscopic sessions was 3.1 ± 1.9 in the anterior resection with anastomosis group and 3.2 ± 1.8 in the Hartmann group. In 11 patients the therapy was administered in an ambulatory setting. The mean time to healing was 22.3 ± 14.7 days. Full resolution was achieved in 19 patients (followed-up 1 year). Ileostomy closure was carried out in 5 patients (38.46%) during follow-up. None of these patients showed leakage signs. Statistically significant differences were obtained depending on the onset of therapy, with better results in patients who underwent earlier vacuum-assisted therapy (before the sixth week after initial surgery), P = .041. CONCLUSIONS: VAC therapy is an alternative to surgery that can be safely administered in an ambulatory setting. Early administration in the 6 weeks following surgery is an independent predictive factor for successful closure; however, colonic transit was only recovered in a small percentage of patients.
