Surgical outcomes in patients with hepatic synchronous and metachronous colorectal metastases.

AIM: To evaluate the impact of several clinical and pathological factors on the outcomes of surgery for hepatic colorectal cancer metastasis. METHODS: Eighty-four liver metastasectomies in 77 consecutive patients with 90 colorectal cancer hepatic metastases were performed in our institution from 2009 to 2014. Surgery was carried out in 75 cases, as two patients were not eligible for surgery. Among them 43 (Group A) were affected by synchronous, and 32 (Group B) by metachronous lesions. Furthermore, 9 reoperations were performed in patients with initially synchronous lesions. The follow-up after surgery included total body CT scan every 3 months for the first year, and every 6 months for 4 years thereafter. Blood level of CEA was determined every 3 months. RESULTS: The univariate analysis evidenced significantly more recurrences in patients with synchronous lesions (p=0.011), and higher grade, pN stage and CEA blood levels. In multivariate logistic regression analysis the statistically significant parameters found were: the pT stage (OR: 3.92, p = 0.039), the use of adjuvant chemotherapy for the colonic tumor (OR: 0.19, p = 0.025), and the adjuvant chemotherapy (OR: 4.11, p = 0.048). The global survival was 32 patients (41.5%), 17 with synchronous and 15 with metachronous lesions, and a significant difference in long-term survival between these two groups was found (p = 0.008). CONCLUSIONS: The most relevant prognostic factor in patients with hepatic colorectal cancer dissemination is the timing of metastasis; the metachronous lesions present better survival when surgically treated.

Thoracoscopic treatment of a broncho-esophageal fistula: A case report.

INTRODUCTION: Broncho-esophageal fistula is a rare clinical condition which can be manifested with non-specific signs and symptoms. PRESENTATION OF A CASE: Here, we report an adult case of a broncho-esophageal fistula in a 43-year-old man referred for chronic cough after fluid food intake and weight loss. Barium swallow, esophagogastroduodenoscopy, bronchoscopy and Computed Tomography of the chest demonstrated a broncho-esophageal fistula between the apical segmental bronchus of the lower right lobe and the middle section of the esophagus. The patient underwent video-assisted thoracoscopic surgery for resection of the fistula. No post-operative complications occurred. DISCUSSION: Broncho-esophageal fistula in adults is rare and its diagnosis is often delayed due to the frequent lack of specific symptoms. Although there is no standard protocol, the most widely used treatment is thoracotomy with identification and dissection of the fistula tract followed by repair of bronchial and esophageal defects. CONCLUSIONS: Video-assisted thoracoscopic surgery appears to be an effective and minimally invasive approach for the treatment of broncho-esophageal fistulas, especially in young, healthy subjects.
