Laparoscopic excision of posterior vaginal fornix in the treatment of patients with deep endometriosis without rectum involvement: surgical treatment and long-term follow-up.

BACKGROUND: The objective of the study is to evaluate the short- and long-term efficacy of complete laparoscopic excision of deep endometriosis, without rectum involvement, with the opening and partial excision of the posterior vaginal fornix.
METHODS: Thirty-one patients were included in the study with symptomatic extensive disease including involvement of the cul-de-sac, rectovaginal space and posterior vaginal fornix without rectum involvement. Endoscopic surgery was performed with complete separation of rectovaginal space and in-block resection of the diseased tissue, opening and partial excision of the posterior vaginal fornix and vaginal closure either by laparoscopic or by vaginal route. Patients filled in questionnaires on pain before and 12, 24, 36, 48 and 60 months after surgical treatment.
RESULTS: No intraoperative complications were observed; 65% were free of analgesic on post-operative day 2, 38% had total remission of chronic pain and 22% were improved; 38% had total remission of dysmenorrhoea and 22% were improved; 45% had total remission of dyspareunia and 25% were improved. Follow-up improvement of symptoms was statistically significant and was maintained for 5 years without recurrence of the disease or repeated surgery (P < 0.001).
CONCLUSION: Complete surgical resection of deep infiltrative endometriosis with excision of the adjacent tissue of the posterior vaginal fornix improves quality of life with persistence of results for long time in patients not responsive to medical treatment.
