Abstract
Objective. Analyze the frequency and prognostic factors of complications in patients with locally advanced cervical esophageal cancer after pharyngolaryngoesophagectomy with simultaneous reconstruction of the defect.Material and methods. The retrospective study included patients with a verified locally advanced cervical esophageal cancer who were treated at the N. N. Petrov National Research Institute of Oncology in the period from 2009 to 2018, who underwent surgical treatment followed by chemoradiotherapy. The end point of the study was the frequency of postoperative complications.Results. Forty-eight patients were included in the study. All patients underwent laryngopharyngoesophagectomy with simultaneous reconstruction of the digestive tract. Forty-one patients (85.4 %) underwent the reconstructive stage using a narrow gastric stalk, and a wide gastric stalk and a small intestine graft were used in 5 (10.4 %) and 2 (4.2 %) patients, respectively. The average duration of the operation was 390 (337.5–525.0) minutes, the volume of blood loss was 300 (200–500) ml, and the average time of hospitalization and the patient’s stay in the intensive care unit was 21.5 (16.00–36.00) and 3 (1.000–6.75) days, respectively. Complications within 30 days after surgical treatment were observed in 54.1 % of patients, while anastomosis failure, fistula formation and pneumonia were observed in 22.9 %, 12.5 % and 18.8 % of cases, respectively. Factors slightly increasing the likelihood of pneumonia in the early postoperative period were: duration of surgery [OR = 1.0 (95 % CI: 1.00–1.01), p = 0.0131] and intraoperative blood loss [OR = 1.0 (95 % CI: 1.00–1.01), p = 0.0017].Conclusion. The overall complication rate after pharyngolaryngoesophagectomy with simultaneous repair of the defect by bioengineered graft was 54.1 %. Intraoperative blood loss and duration of surgery were associated with an increased risk of complications.
