The hospital records of patients undergoing major surgery for cancer of the larynx and hypopharynx at the Tata Memorial Hospital, Bombay, from 1981 to 1985 were reviewed. Different variables were correlated with the incidence of major complications and were analysed to find out significant factors contributing to increased complication rates. Complications included wound infection, pharyngocutaneous fistulae, flap necrosis, carotid blowout, and neo-esophageal stenosis. Postoperative deaths and delayed fatalities were also recorded. The overall fistulae rate was 34.7%, and wound infection occurred in 28% of patients. Prior radiotherapy and the need for pharyngeal reconstruction were found to be significant in determining postsurgical complications. Age, sex, site, stage, cartilage and soft tissue infiltration, preoperative tracheostomy, involvement of resection margins by tumor, and the dose of radiotherapy were not found to influence the complication rates.

Seventy-five patients underwent gastric transposition for replacement of the pharyngoesophagus. These patients had primary or recurrent malignant tumors of the hypopharynx, postcricoid region, and cervical esophagus. The operative procedure consisted of a transhiatal esophagectomy and gastric pull-up to establish gastrointestinal continuity, with a unilateral or bilateral neck dissection where indicated. Seven patients died, a mortality rate of 9.33%. The average hospital stay of uncomplicated cases was 18 days and for complicated cases was 40 days. Immediate restoration of oral intake was achieved in 70.6% of patients. We conclude that gastric transposition after circumferential laryngopharyngeal excision is a procedure with low mortality and acceptable morbidity leading to early relief of dysphagia.

A 3-year prospective study on primary tracheoesophageal puncture was carried out at Nanavati Hospital and Tata Memorial Hospital, Bombay, to assess its feasibility in a developing country and its success in vocal rehabilitation. We report our experience with primary tracheoesophageal puncture in 64 patients (57 males and 7 females) following surgical treatment for carcinoma of the pyriform fossa (45 cases) and endolarynx (19 cases). All patients underwent total laryngectomies with or without partial pharyngectomy and primary pharyngeal mucosal closure. Fifty-one patients underwent primary surgery followed by postoperative radiotherapy. At 3 months successful tracheoesophageal speech was achieved in 84% patients, although this percentage decreased to 67% at 9 months. There were no major complications. Successful vocal rehabilitation was related more to "patient factors" such as delays in seeking medical attention when prosthetic valves dislodged, improper use and care of the valves and inability to learn speech with the prosthesis. Overall, primary tracheoesophageal puncture was found to be feasible and should be used more extensively for vocal rehabilitation following laryngectomy in developing countries.

In Indian scenario where illitracy amongst the patients hinders in maintainence of Blom-Singer® prosthesis, Provox® indwelling value is an appropriate choice for voice rehabilitation.
