RESULTS The instruments most frequently used were single-item VAS and Biberoglu and Behrman pain score , while multidimensional inventories were used in few studies .
The results of clinical studies in CPP are more frequently based on one-dimensional measurements .
RATIONALE Many types of  pain assessment are available to research ers carrying out clinical trials in chronic pelvic pain ( CPP ) , ranging from a single-item scale to multidimensional inventories .
AIM Our objective was to investigate which assessment s of pain are more commonly used in clinical trials on CPP .
A prospective, randomized study comparing laparoscopic ovarian cystectomy versus fenestration and coagulation in patients with endometriomas.
OBJECTIVE To determine the difference between two laparoscopic methods for the management of endometriomas with regard to recurrence of signs and symptoms and pregnancy rate . DESIGN Prospect i ve , r and omized clinical trial . SETTING Infertility and gynecologic endoscopy units of two medical university hospitals . PATIENT(S ) One hundred patients with endometriomas who had either infertility or pelvic pain . INTERVENTION(S ) Patients were r and omly divided into two groups ; one group underwent cystectomy ( group 1 ) , and fenestration and coagulation were performed for the other ( group 2 ) . MAIN OUTCOME MEASURE(S ) A comparison of recurrence of signs and symptoms of endometriomas and pregnancy rates in two groups . RESULT ( S ) Fifty-two patients were studied in group 1 and 48 in group 2 . The recurrence of symptoms , such as pelvic pain and dysmenorrhea , was 15.8 % in group 1 and 56.7 % in group 2 after 2 years . The rate of reoperation was 5.8 % in group 1 and 22.9 % in group 2 and these differences were statistically significant . The cumulative pregnancy rate was significantly higher in group 1 ( 59.4 % ) than in group 2 ( 23.3 % ) at 1-year follow-up . CONCLUSION ( S ) Laparoscopic cystectomy of endometriomas is a better choice than fenestration and coagulation because the former technique leads to a lower recurrence of signs and symptoms and a lower rate of reoperation and a higher cumulative pregnancy rate than the latter
