Comparison of the impact of laparoscopic endometriotic cystectomy and vaporization on postoperative serum anti-Mullerian hormone levels.

Introduction: The aim of this study was to investigate the effect of laparoscopic endometriotic cystectomy and vaporization on ovarian reserve.

Methods: We prospectively analyzed the serum level of anti-Mullerian hormone (AMH) in 62 patients at four different time points- preoperatively and at 1 month, 6 months, and 1 year postoperatively. Among the 62 cases, a bilateral cystectomy was performed in 10, bilateral vaporization in 16, a unilateral cystectomy in 24, and unilateral vaporization in 12.

Compared with cystectomy, is ovarian vaporization of endometriotic cysts truly more effective in maintaining ovarian reserve?

Study Objective: To evaluate how endometriotic cystectomy and vaporization affect ovarian reserve after conservative surgery.

Design: Prospective study (Canadian Task Force classification II-1).

Setting: Hokusetsu General Hospital.

The expression status of G protein-coupled receptor GPR30 is associated with the clinical characteristics of endometriosis.

Introduction: GPR30 is a seven-transmembrane G protein-coupled estrogen receptor that regulates endometrial cellular responses to estrogen. GPR30 is often highly expressed in cancer cells from aggressive tumors. The aim of this study was to evaluate the expression patterns of GPR30 in endometriosis during medical treatment.

Preoperative assessment by magnetic resonance imaging is useful for planning the treatment of an enlarged uterus by total laparoscopic hysterectomy.

Aim: The purpose of this study was to compare the intraoperative and postoperative parameters among the three approaches used to treat large uterine myomas: laparoscopic assisted vaginal hysterectomy (LAVH), total laparoscopic hysterectomy (TLH) and abdominal hysterectomy, and to evaluate the selection criteria for laparoscopic hysterectomy as determined by magnetic resonance imaging.

Material And Methods: The medical records of 155 patients who underwent a hysterectomy between January 2007 and April 2010 were examined. We also compared the indications and outcomes of LAVH and TLH for myomas larger than 7 cm.

Dienogest increases the progesterone receptor isoform B/A ratio in patients with ovarian endometriosis.

Background: The resistance of endometriotic tissue to progesterone can be explained by alterations in the distribution of progesterone receptor (PR) and estrogen receptor (ER) isoforms. The aims of this study were to examine the expressions of PR-A, PR-B, ERα and ERβ in endometrioma and assess whether these expressions are affected by dienogest or leuprolide acetate (LA) treatment.

Methods: We enrolled 60 females, including 43 patients with endometriosis (14 who received no medical treatment, 13 who received dienogest and 16 who received LA before undergoing laparoscopic surgery) and 17 patients with leiomyoma.

Objective: To report a case of mature cystic teratoma of the fallopian tube.

Design: Case report.

Setting: Medical college-affiliated hospital.
