[Economics analysis of endometriosis and adenomyosis surgeries].

OBJECTIVE: To explore the hospital expenses and hospital stay of surgical management for endometriosis and adenomyosis. METHODS: The average hospital expenses and average hospital stay were compared for a total of 12003 patients of endometriosis and adenomyosis confirmed operatively at our hospital from January 1994 to December 2008. And the relevant factors consisted of surgical phases, pathological types, surgical approaches, surgical routes, definite procedures and age groups. RESULTS: The average hospital expenses were significantly higher than average gynecologic surgical expenses (RMB 7073 vs RMB 6847, P < 0.01) while and the average hospital stays significantly shorter than the latter (6.8 vs 8.6 days, P < 0.01). The periods of 2006 - 2008 and 1994 - 1996 had significantly different average hospital expenses (RMB 7853 vs RMB 3382, P < 0.01) and average hospital stay (6.4 vs 9.5 days, P < 0.01). Multivariate analysis showed age was the most important correlated factor for the hospital expenses of endometriosis and adenomyosis surgeries (all P < 0.01). And surgical approach was one of the most important factors for hospital stay (all P < 0.01). CONCLUSION: Adenomyosis has the highest cost and younger endometriosis patients carry the lowest economic burden. Laparoscopy and conservative surgery may reduce the economic burden of endometriosis and adenomyosis operations.
