To serve as a pilot feasibility study for a randomized study of excision versus ablation in the treatment of endometriosis by (1) estimating the magnitude of change in symptoms after excision only at multiple referral centers and (2) determining the proportion of women willing to participate in a randomized trial.
Methods
We performed a multicenter prospective study of women undergoing excision for endometriosis (Canadian Task Force class II-3) at Duke University Center for Endometriosis Research & Treatment (currently the Saint Louis University Center for Endometriosis), Center for Endometriosis Care, Northshore University Health System, Memorial University (Canada), and Florida Hospital. The study comprised 100 female patients, aged 18 to 55 years, with endometriosis-suspected pelvic pain. The intervention was laparoscopic excision only of the abnormal peritoneum suspicious for endometriosis. The main outcome measures were quality of life, pelvic pain, dysmenorrhea, dyspareunia, and bowel and bladder symptoms.
Results
The mean follow-up period was 8.5 months. Excision of endometriosis showed a significant reduction in all pain scores except bowel symptoms, as well as significant improvement in quality of life. Of the patients, 84% were willing to participate in a randomized study.
Conclusions
Quality of life is a needed primary outcome for any randomized study comparing excision versus ablation. A multicenter comparative trial is feasible, although quality assurance would have to be addressed. Patients were willing to be randomized even at surgical referral centers.

To present a case of recurrent catamenial pneumothorax and diaphragmatic endometriosis that was managed thoracoscopically. A review of the literature is also presented. A-28-year-old woman presented with bloody stools, chronic constipation, and chest pain. A review of systems was positive for monthly chest pain associated with her menses. A preoperative chest x-ray revealed a right pneumothorax. Colonoscopy revealed biopsy proven endometriosis of the sigmoid colon. A pelvic computed tomography scan revealed bilateral complex, cystic and solid adenexal lesions. A right thoracoscopy was performed. A lesion on the right hemidiaphragm was excised and confirmed to be endometriosis. A wedge section of lung tissue containing a bleb was resected and also contained endometriosis. Three months later, the patient underwent laparoscopic excision of her pelvic endometriosis, including a low anterior rectal resection. Five months later, she presented again with right-sided chest pain. A thoracoscopic right total pleurectomy was performed for recurrent pneumothorax. Pullmonary endometriosis may present as chest pain, shortness of breath, or hemoptysis associated with menstrual cycles. This case emphasizes the importance of a careful review of systems in patients with known endometriosis. Management now includes an endoscopic alternative and all of its known benefits.
This study aimed to explore the optimal time of laparoscopic cystectomy for unilateral ovarian endometrioma patients and evaluate the influence on ovarian reserve. This prospective randomized controlled study included 88 women with unilateral ovarian endometrioma at a tertiary teaching hospital. All patients received their first identified diagnosis of ovarian endometrioma by ultrasound (> 4 cm and ≤ 10 cm) and were administered an oral contraceptive pill (OC) for one cycle before laparoscopy. They were randomly laparoscopy at the late luteal phase (group LLP) (n = 44) (termination of OC for two days) and laparoscopy at the early follicular phase (group EFP) (n = 44) (day 3 after menstruation). Basic clinical characteristics were recorded. Serum Anti-Müllerian hormone (AMH) levels were measured at various times to predict ovarian reserve. Serum levels of Anti-Müllerian hormone (AMH) were measured at several time sites to predict the ovarian reserve; AMH and leukocyte esterase (LE) levels of the endometrioma wall were measured. Before surgery, serum AMH levels decreased in both groups from preoperative to one week and six months postoperatively. In contrast, the difference values of group EFP were larger than those of group LLP at postoperative one week and postoperative six months (1.87 ± 0.97 vs. 1.31 ± 0.93, P = 0.07; 1.91 ± 1.06 vs. 1.54 ± 0.93, P = 0.001). The mean rates of postoperative serum AMH decline were 37.92% and 46.34% in group EFP, significantly higher than those in group LLP (25.83% vs. 31.43%, P < 0.001). Ovarian endometrioma wall AMH of group LLP was significantly lower than that of group EFP ([22.86 ± 3.74] vs. [31.02 ± 5.23], P < 0.001). Meanwhile, ovarian endometrioma LE concentration of group LLP was significantly higher than that of group EFP ([482.83 ± 115.88] vs. [371.68 ± 84.49], P<0.001). There was also a significant inverse correlation between leukocyte esterase and AMH concentration in an ovarian endometrioma cyst wall (r=-0.564, P<0.001). CONCLUSION(S): The optimal time for laparoscopic cystectomy for patients with first identified unilateral ovarian endometrioma is the late luteal phase, which reduces ovarian tissue loss and preserves ovarian reserve effectively and safely.
Tubal endometriosis (TEM) is a category of pelvic endometriosis (EM) that is characterized by ectopic endometrial glands and/or stroma within any part of the fallopian tube. The fallopian tubes may be a partial source of ovarian endometriosis (OEM). TEM is difficult to diagnose during surgery and is usually detected by pathology after surgery. To provide a clinical basis for the diagnosis and treatment of TEM. In this study, the data of 30 patients who underwent laparoscopic salpingectomy due to various gynecological diseases and had pathological confirmation of TEM at our hospital were retrospectively analyzed, and the clinical basis for the diagnosis and treatment of TEM was evaluated. Among 1982 surgical patients, 30 met the study criteria. Among those, 6 patients had a history of infertility, 12 patients had a history of artificial abortion, 13 patients had a history of cesarean section, 1 patient had a history of tubal ligation, 4 patients had an intrauterine device, and 22 patients had hydrosalpinx. Sixteen patients (53.33%) conceived naturally and gave birth to healthy babies. Pathology showed that only 2 patients had TEM without any other gynecological diseases, while the others all had simultaneous diseases, including 26 patients with EM at other pelvic sites. The final diagnosis of TEM depends on pathological examination since there are no specific clinical characteristics. The rate of TEM combined with EM (especially OEM) was higher than that of other gynecological diseases, which indicates that TEM is related to OEM.
Background Endometriosis can be associated with considerable pain and sterility. After surgical excision of moderate or severe endometriosis lesions, the rate of recurrence reaches up to 67%. The objective of this retrospective study was to establish the recurrence and pregnancy rates following surgical resection of stage III/IV endometriosis lesions. Indications for operation were endometriosis symptoms, sonographic findings and/or infertility. Methods A total of 456 patients who underwent stage III/IV endometriosis surgery between 2004 and 2014 were sent a questionnaire relating to their postoperative medical treatment, pregnancies, relief of symptoms and recurrence. Responses of 206 patients (45.2%) and their clinical data were analysed for this study. Results A total of 66.5% ( N = 137) of patients had stage III disease, and 33.5% ( N = 69) had stage IV disease. The average age was 37 years (17–59). A total of 63.1% ( N = 130) of surgeries were performed by laparoscopy, 21.8% ( N = 45) were performed by laparotomy and 15% ( N = 31) were performed by conversion. Complete resection of endometriosis lesions was achieved in 90.8% of patients ( N = 187). After surgery, 48.5% ( N = 100) of the women did not receive hormonal treatment; the main reason was the desire for children in 53%. Complete or partial relief in complaints was achieved in 93.2% ( N = 192). The rate of recurrence was 21.8% ( N = 45). The statistically significant factors that was associated with a higher risk to develop recurrence was an age < 35 ( p < 0.005). After surgery, 65.8% (79/120) of patients who wished to have children became pregnant. There was a statistically significant association among a higher postoperative pregnancy rate and age < 35 ( p < 0.003) in multivariate logistic regression analysis and laparoscopic surgical access in univariate logistic regression analysis ( p < 0.01). Conclusion We assessed the high percentage of complete or partial relief of symptoms of 93.2%, the high postoperative pregnancy rate of 65.8% and the low rate of recurrence of 21.8% compared to international literature to be very encouraging for women suffering from moderate and severe endometriosis. Though laparoscopy is considered the ‘gold standard’of endometriosis surgery, laparotomy still may be indicated in patients with extensive endometriosis especially to preserve reproductive function.
