[Pharyngogastric or pharyngocolonic anastomosis in esophageal reconstruction for hypopharyngeal cancer or esophageal disease].
OBJECTIVE
To evaluate the surgical indications and postoperative morbidity of pharyngogastric anastomosis or pharyngocolonic anastomosis in esophageal reconstruction for advanced hypopharyngeal and cervical esophageal neoplasms or diffuse corrosive hypopharyngoesophageal stricture.


METHODS
Retrospectively analysis the experience and results of 52 patients undergoing esophageal reconstruction with pharyngogastric anastomosis and 66 patients with pharyngocolonic anastomosis. In the group of neoplasms, total esophagectomy with pharyngogastric anastomoses in 52 cases and with pharyngo-colonic anastomosis in 35 cases. Thirty-one cases with diffuse corrosive hypopharyngoesophageal stricture were treated by pharyngo-colonic anastomosis without resection of the strictured intrathoracic esophagus.


RESULTS
In the group of neoplasm E, preservation of laryngeal functions in pharyngogastric anastomoses was performed in 28/52 cases and that of in pharyngo-colonic anastomosis was in 18/35 cases. There was no significant difference in preservation of laryngeal functions between two groups (P > 0.05). Pharyngocutaneous fistula was happened in 23 patients which significant higher in the group of pharyngocolonic anastomosis (17/66 cases) than that of pharynogogastric anasromoses (5/52 cases) (P < 0.05). Gastric reflux was presented in 19 cases and there was significant higher in pharyngogastric anastomoses (16/52 cases) than that of (3/66 cases) (P < 0.05).


CONCLUSIONS
Substitution of esophagus with stomach or colon can completely removed the neoplasms of hypopharynx or cervical esophagus and preserved laryngeal functions in selected patients. But gastric reflux is a challenging reconstructive problem in pharyngogastric anastomosis. Pharyngocolonic anastomosis should take into consideration to patients with extensive neoplasms and diffuse corrosive stricture or probably preserved the laryngeal functions. However, the swallow function is weak and the incidence of pharyngocolonic fistula is higher than that of pharyngogastric anastomosis.
