[Long-term follow-up after complete treatment of peritoneal endometriosis with the CO2 laser].
OBJECTIVE
To evaluate the effect of laparoscopic CO2 laser ablation of peritoneal endometriosis in the treatment of pelvic pain with a long-term follow-up. To differentiate the effect of surgery on different types of pelvic pain.


METHODS
Prospective observational study.


METHODS
Department of Obstetrics and Gynecology, 1st Medical Faculty, Charles University and General Faculty Hospital, Prague.


METHODS
Patients with 1st to 3rd stage endometriosis, with manifestation of pelvic pain, and with complete excision of peritoneal endometriosis lesions, were included in the study. All visible lesions were vaporized by CO2 laser following adhesiolysis and complete visualization of the pelvis. After the procedure, patients were followed up at 6-month intervals. The severity of pelipathia, dyspareunia, dysmenorrhea, pain during micturition, and pain during defecation were monitored using a visual analog score of 10 points.


RESULTS
A total of 31 patients were included in the study. After 6, 12, and 18 months after surgery, the recurrence of pelvic pain was found in 12 (39%), 15 (48%), and 19 (61%) patients, respectively. Improvement or disappearance of complaints was documented 18 months after the surgery in 11 cases of dysmenorrhea (50%), 9 cases of dyspareunia (50%), 14 cases of pelipathia (58%), 12 cases of pain during micturition (71%), and in 14 cases of pain during defecation (87.5%). The proportion of recurrences increases with the length of the interval after the procedure, mainly in dysmenorrhea and dyspareunia.


CONCLUSIONS
The effect (improvement or disappearance of pelvic pain) of a complete CO2 laser ablation of peritoneal endometriosis continues 18 months after the surgery in about 40% of patients. A graduated increase in the number of recurrences is apparent during follow-up, most significantly in dysmenorrhea and dyspareunia. The effect of surgery on different types of pelvic pain varies. A small number of recurrences was found in pain during micturition and pain during defecation, on the other hand, less success was apparent in the treatment of dysmenorrhea.
