Introduction: Post operative leaks of esophageal anastomosis after esophagectomy is a risky event associated with poor postoperative evolution. Its frequency and severity will depend mainly on surgical technical aspects. Objectives: To analyze the frequency, management and prognosis of leakage of esophageal anastomosis after esophagectomy for esophageal cancer. Material and Method: Analysis of our prospective oncologic database of patients with esophageal cancers submmitted to esofagectomy. Statistical analysis with Fisher’s exact test. Results: 34 out of 37 esophageal cancer patients were included submitted to completely invasive mini esophagectomy. Cervical anastomosis was performed in 79.4% of patients, in the remaining 20.6%, a distal esophagectomy with intrathoracic anastomosis was performed. The leak rate was 38.2% (13/34), of these, 69.2% (9/13) correspond to grade Clavien - Dindo I - II complications. The leak rate was 54.5% (6/11) for retro-sternal gastric ascensus and 43.7% (7/16) for mediastinal route, without significative difference (p = 1.0). The reoperation rate was 11.7%, being a 100% secondary to mediastinal ascensus, 3 of them were submitted to thoracoscopic toilets and an innominate vein repair. Postoperative mortality rate was 5.8%, all concentrated in the group of patients with posterior mediastinal ascensus, but without statistical difference (p = 0.26). Conclusion: Leaks are frequent in patients operated on for esophageal cancer, especially after cervical esophago-gastro-anastomosis with anterior route for ascensus. However, retro-sternal ascensus did not require re-operations, nor postoperative mortality compared to gastric ascensus through posterior mediastinum |
