This study aimed to introduce the clinical outcomes of conservative surgery for diffuse uterine leiomyomatosis, which also included the specialized surgical technique. All patients with diffuse uterine leiomyomatosis underwent conservative surgery such as transient occlusion of the uterine arteries (TOUA) adenomyomectomy. All 17 surgeries were performed by a single surgeon between 2018 and 2021.

Background And Objective: Owing to the increasing trend of preserving fertility in adenomyomectomy, the need for laparoscopic adenomyomectomy has increased. This study aimed to introduce a new surgical technique, an advanced laparoscopic adenomyomectomy technique, and to evaluate its efficacy, benefits, and safety in focal uterine adenomyosis.

Methods: From February 1, 2019 to February 29, 2020, 47 patients who underwent laparoscopic adenomyomectomy using the new surgical technique were enrolled in the study.

Objective: Although adenomyomectomy for fertility-sparing is an expanding procedure worldwide, there is no guideline or consensus about how to manage the pregnant women who have previously received conservative surgery for adenomyosis. The aim of this study is to evaluate antenatal care and delivery outcomes in pregnant women after adenomyomectomy.

Materials And Methods: Between May 2011 and May 2019, the medical record was reviewed in all delivery of pregnant women received adenomyomectomy performed by a single surgeon by a uniform surgical technique.

A 39-year-old nulliparous woman experienced continuous mild fever and abdominal pain since undergoing laparoscopic ovarian dermoid cystectomy 3 months previously in a local hospital. Abdominal computed tomography revealed diffuse heterogeneous fat infiltrations with numerous micronodules in the greater and lesser omentum, combined with ascites with thickening of the parietal peritoneum. The patient underwent exploratory laparoscopy, which included partial pelvic peritonectomy, excision of granulomas, and adhesiolysis with massive irrigation.

Dienogest (DNG) is a progestin with highly selective progesterone activity and known to be effective in the treatment of endometriosis. This prospective cohort study in patients who had been treated with DNG 2 mg (Visanne) for endometriosis was conducted to assess the safety and effectiveness of DNG in a large Korean cohort. This study included 3356 patients with endometriosis from 73 centers in Korea.

Introduction: Uterine-conservative surgery via laparoscopy is a challengeable and high risk because of heavy intra-operative bleeding events in reproductive women with highly vascular uterine benign disease. There are three reported cases of women with highly vascular uterine benign diseases and high risk of intra-operative heavy bleeding, but were treated successfully to control intra-operative heavy bleeding risk by transient occlusion of the uterine artery (TOUA) through laparoscopy and resulted in safe conservation of the uterus.

Case Presentation: The cases of women with high risk of heavy bleeding during therapeutic procedure included cesarean scar pregnancy, hydatid form mole on cesarean scar, and cervical pregnancy.

Aim: The aim of this study was to evaluate immediate pain control in patients who underwent laparoscopic myomectomy (LM) by intraoperative injection of ropivacaine into both uterosacral ligaments.

Methods: The study was a prospective, double-blind, randomized study. We analyzed 46 cases of LM performed between July 2015 and November 2016 by a single surgeon.

Objective: Although laparoscopic hysterectomy, a worldwide popular surgery, ensures faster recovery and less postoperative pain than with laparotomic hysterectomy, immediate pain control still improving postoperative care. We introduce an effective method, intraoperative injection of ropivacaine into both uterosacral ligaments, to control immediate postoperative pain.

Materials And Methods: We performed a prospective, double-blind, and randomized study.

The aim of this study is to evaluate the clinical outcomes of conservative adenomyomectomy with TOUA for diffuse uterine adenomyosis and to determine the feasibility and safety. One hundred and sixteen patients with symptomatic diffuse uterine adenomyosis underwent adenomyomectomy with TOUA by a single surgeon at Ulsan University Hospital between May 2011 and March 2016. Surgical outcomes included operative time, intraoperative injury and operative blood loss.

Background And Objectives: For conservative surgical treatment of focal uterine adenomyosis, laparoscopic adenomyomectomy has been increasingly performed, so that reassessment to determine the safety and efficacy of the laparoscopic surgical technique in a larger number of cases and reevaluation for reproducibility for laparoscopic adenomyomectomy is needed. We evaluate the clinical outcomes of laparoscopic adenomyomectomy with transient occlusion of uterine arteries (TOUA) for focal uterine adenomyosis performed by a single surgeon at a single institute.

Methods: Patients (N = 105) with symptomatic focal uterine adenomyosis underwent laparoscopic adenomyomectomy with TOUA by a single surgeon at Ulsan University Hospital from May 1, 2011, through September 30, 2016.

A 38-year-old nulliparous woman was referred to our clinic because of cervical incompetence at 19 weeks of gestation. Trans-abdominal cervicoisthmic cerclage was performed after failure of modified Shirodkar cerclage operation in the patient at 21 weeks of gestation via a laparotomic approach. Another 38-year-old patient, who underwent loop electrosurgical excision procedure conization for treatment of cervical dysplasia 4 years ago, presented for cervical incompetence.

A 31-year-old nulliparous woman with severe diffuse uterine adenomyosis, which replaced nearly the whole uterine myometrium, visited our hospital due to severe dysmenorrhea, menorrhagia, and a desire to have a baby. The patient had a history of two spontaneous abortions. Laparotomic adenomyomectomy with transient occlusion of uterine arteries (TOUA) was performed safely and the patient tried in vitro fertilization and achieved a intrauterine twin pregnancy after recovery time of the operation.

There are few methods to control heavy intra-operative bleeding during cesarean delivery of placenta previa. Transient occlusion of uterine arteries (TOUA) during operation has previously been reported as a quick and safe method to control intra-operative uterine bleeding. We reported 2 cases of cesarean delivery with complete placenta previa in which TOUA was performed to safely reduce intra-operative complication, especially heavy intra-operative bleeding.

Ovarian microcystic stromal tumor (MCST) is a very rare neoplasm; hence, its nomenclature was recently designated as "Distinctive morphologic and immunohistochemical features" in 2009. Its exact origin, etiological genetic alterations, and background are not yet clearly known. Familial adenomatous polyposis (FAP) is an autosomal dominant disease that leads to development of colorectal polyps via germ-line mutations of the APC gene on chromosome 5q21∼22.
