[Retrospective study of complications of surgery for laryngeal cancer]

Surgery, alone or in combination with other therapeutic measures, is one of the main approaches to curing laryngeal cancer. The risk of complications is implicit in any surgical procedure. We describe our experience with general and local complications in surgery for laryngeal cancer and examine their relation to tumor extension and surgical technique. A review was made of a series of 431 patients who underwent surgery for laryngeal cancer over a 10-year period (1982-1991). Twenty-two patients (5.1%) had systemic complications, including upper gastrointestinal hemorrhage (n = 5), massive cervical hemorrhage (n = 5), and four renal failure. Minor complications were recorded in 77 cases (17.8%), predominantly pharyngocutaneous salivary fistula, which developed in 55 patients (13.8%). The incidence of local complications was significantly greater in patients with extensive local spread (T4). There were no differences among patients with regional spread. The surgical technique and type of pharyngoesophageal reconstruction played no role in the development of complications. Preoperative radiotherapy did not influence on the development of salivary fistulas.
