Recurrence, Reoperation, Pregnancy Rates, and Risk Factors for Recurrence after Ovarian Endometrioma Surgery: Long-Term Follow-Up of 756 Women

Purpose@#The aims of this study were to evaluate the cumulative recurrence, reoperation, and pregnancy rates after ovarian endometrioma surgery at a single institution for more than a 5-year follow-up period. @*Materials and Methods@#This study was conducted as a retrospective chart review of patients with ovarian endometrioma who underwent surgery between January 2008 and March 2016. Study subjects included premenopausal women with at least 5 years of follow-up. Exclusion criteria were patients with stage I or II ovarian endometrioma, those who underwent hysterectomy or bilateral oophorectomy, and presence of residual ovarian lesions on the first postoperative ultrasonography at 3–6 months. Recurrence was defined as a cystic mass by ultrasonography. @*Results@#A total of 756 patients were recruited. The median follow-up duration was 85.5 months (interquartile range, 71–107 months). Recurrent endometrioma was detected in 27.9% patients, and reoperation was performed in 8.3% patients. Cumulative rates at 24, 36, 60, and 120 months were 5.8%, 8.7%, 15.5% and 37.6%, respectively, for recurrence and 0.1%, 0.5%, 2.9%, and 15.1%, respectively, for reoperation. After multivariable analysis, age ≤31 years [hazard ratio (HR)=2.108; 95% confidence interval (CI)=1.522–2.921; p<0.001], no subsequent pregnancy (HR=1.851; 95% CI=1.309–2.617; p<0.001), and postoperative hormonal treatment ≤15 months (HR=2.869; 95% CI=2.088–3.941; p<0.001) were significant risk factors for recurrent endometrioma. Among 315 patients who desired pregnancy, 54.0% were able to have a successful pregnancy and delivery. @*Conclusion@#Considering that longer postoperative hormonal treatment is the sole modifiable factor for recurrent endometrioma, we recommend long-term hormonal treatment until subsequent pregnancy, especially in younger women.

Cumulative Recurrence Rate and Risk Factors for Recurrent Abdominal Wall Endometriosis after Surgical Treatment in a Single Institution

Purpose@#This study aimed to evaluate the cumulative recurrence rate and risk factors for recurrent abdominal wall endometriosis (AWE) after surgical treatment. @*Materials and Methods@#A retrospective cohort study was conducted at a single gynecological surgery center between January 2004 and December 2020. Patients who were surgically treated and followed up for at least 6 months after surgery were selected. @*Results@#Eighteen patients with pathologically diagnosed AWE were included in this study. The median follow-up duration was 22.5 months (range, 6–106). The median age was 37 years (range, 22–48), and 33.3% of the patients were nulliparous. Among the patients included in our study, 55.6% complained of a mass with cyclic pain, and 27.8% had a palpable mass. In addition, 22.2% of patients experienced recurrence with 17.5±9.7 months of mean time to recurrence. The cumulative recurrence rates at 24 and 60 months after surgical treatment of AWE were 23.8% and 39.1%, respectively. There were no statistically significant risk factors for the recurrence of AWE, including postoperative medical treatment. @*Conclusion@#The recurrence rate of AWE appears to be correlated with the follow-up duration. There was no statistically significant risk factor for the recurrence of AWE. Unlike ovarian endometriosis, postoperative hormonal treatment does not seem to lower the recurrence of AWE. The findings of the current study may help healthcare providers in counselling and managing patients with AWE.

Robotic-assisted laparoscopic myomectomy: the feasibility in single-site system

OBJECTIVE: To evaluate the feasibility of robotic single-site myomectomy (RSSM). METHODS: Medical records of 355 consecutive women who underwent robotic-assisted laparoscopic myomectomy were retrospectively reviewed. Clinical characteristics were compared between multi-site and single-site systems. After 1:1 propensity score matching for the total myoma number, largest myoma size, and total tumor weight (105 women in each group), surgical outcomes were also compared between the 2 systems. RESULTS: A total of 105 (29.6%) and 250 (70.4%) women underwent RSSM and robotic multi-site myomectomy (RMSM), respectively. RSSM was more commonly performed in women with lower body mass index (21.6 vs. 22.5 kg/m2, P=0.014), without peritoneal adhesions (7.6% vs. 24.8%, P < 0.001), and less (2.6 vs. 4.6, P < 0.001) and smaller (6.3 vs. 7.7 cm, P < 0.001) myomas compared to RMSM. After propensity score matching, the largest myoma size (P=0.143), total myoma number (P=0.671), and tumor weight (P=0.510) were not significantly different between the 2 groups. Although the docking time was significantly longer in the RSSM group (5.1 vs. 3.8 minutes, P=0.005), total operation time was similar between RSSM and RMSM groups (145.9 vs. 147.3 minutes, P=0.856). Additionally, hemoglobin decrement was lower in the RSSM group than in the RMSM group (1.4 vs. 1.8 g/dL, P=0.009). No surgical complication was observed after RSSM, while 1 ileus and 2 febrile complications occurred in women that underwent RMSM (0% vs. 2.9%, P=0.246). CONCLUSION: Although RMSM is preferred for women with multiple large myomas in real clinical practice, RSSM seems to be a feasible surgical method for less complicated cases, and is associated with minimal surgical morbidity.

Successful in vitro fertilization pregnancy and delivery after a fertility-sparing laparoscopic operation in a patient with a papillary thyroid carcinoma arising from a mature cystic teratoma / 대한생식의학회지

Malignant transformation of ovarian mature cystic teratomas is rare, and papillary thyroid cancer occurs in 0.1%–0.3% of ovarian teratomas that undergo malignant transformation. We describe a case of successful in vitro fertilization pregnancy and delivery after a fertility-sparing laparoscopic operation in a patient with papillary thyroid carcinoma arising from a mature cystic teratoma.

Uterine fibroid shrinkage after short-term use of selective progesterone receptor modulator or gonadotropin-releasing hormone agonist

OBJECTIVE: The aim of this study was to evaluate the effect of short-term use of selective progesterone receptor modulator (SPRM) or gonadotropin-releasing hormone (GnRH) agonist on uterine fibroid shrinkage among Korean women. METHODS: This retrospective study involved 101 women with symptomatic uterine fibroids who received ulipristal acetate (SPRM, n=51) and leuprolide acetate (GnRH agonist, n=50) for 3 months between November 2013 and February 2015. The fibroid volume was measured both before and after treatment using ultrasonography, computed tomography, and magnetic resonance imaging. The outcomes were compared between the SPRM and GnRH agonist groups. RESULTS: The median rate of fibroid volume reduction after SPRM treatment was 12.4% (IQR −14.5% to 40.5%) which was significantly lower than the reduction rate observed after GnRH agonist treatment (median 34.9%, IQR 14.7% to 48.6%, P=0.004). 19 of 51 (37.3%) patients with SPRM treatment did not show any response of volume shrinkage, while 7 of 50 (14.0%) women with GnRH agonist showed no response (P=0.007). CONCLUSION: Short-term SPRM treatment yields lower volume reduction than GnRH agonist treatment in Korean women with symptomatic fibroids. Further large-scale randomized trials are needed to confirm our findings.

Therapeutic outcomes of methotrexate injection in unruptured interstitial pregnancy

OBJECTIVE: To examine the therapeutic outcomes of methotrexate (MTX) in the treatment of unruptured interstitial pregnancy. METHODS: We reviewed the medical records of patients who were diagnosed with interstitial pregnancy and received MTX as first-line treatment between January 2003 and July 2014 at CHA Gangnam Medical Center. The treatment success rates and subsequent pregnancy outcomes were examined. RESULTS: Ninety-seven patients were diagnosed with interstitial pregnancy between January 2003 and July 2014. Of them, 38 initially received MTX treatment. The diagnosis was made at a median of 6+3 weeks (5+0 to 11+3 weeks). Thirty patients received a systemic MTX injection, while the other 8 received a local MTX injection. Systemic treatment composed of an 8-day alternating MTX regimen, single-dose regimen, or high-dose regimen (100 mg/m2 + 200 mg/m2 intravenously over 12 hours). The local injection consisted of a direct MTX injection into the gestational sac with or without systemic MTX injection. Twenty-one patients (55.3%) were successfully treated with MTX. However, MTX therapy failed in 17 patients (44.7%), who required surgery. Mode of MTX treatment was the only predictive variable of MTX treatment success (P=0.039). Treatment success was seen in 7 of 8 patients (87.5%) in the local MTX group vs. 14 of 30 patients (46.7%) in the systemic MTX group. After treatment, 13 patients attempted a successive pregnancy; of them, 10 patients had a confirmed clinical pregnancy and healthy live birth. CONCLUSION: Combined MTX treatment including a local injection might be an initial approach to the treatment of interstitial pregnancy.

Dilatation and curettage is more accurate than endometrial aspiration biopsy in early-stage endometrial cancer patients treated with high dose oral progestin and levonorgestrel intrauterine system / 부인종양

OBJECTIVE: To determine whether less invasive endometrial (EM) aspiration biopsy is adequately accurate for evaluating treatment outcomes compared to the dilatation and curettage (D&C) biopsy in early-stage endometrial cancer (EC) patients treated with high dose oral progestin and levonorgestrel intrauterine system (LNG-IUS). METHODS: We conducted a prospective observational study with patients younger than 40 years who were diagnosed with clinical stage IA, The International Federation of Gynecology and Obstetrics grade 1 or 2 endometrioid adenocarcinoma and sought to maintain their fertility. The patients were treated with medroxyprogesterone acetate 500 mg/day and LNG-IUS. Treatment responses were evaluated every 3 months. EM aspiration biopsy was conducted after LNG-IUS removal followed D&C. The tissue samples were histologically compared. The diagnostic concordance rate of the two tests was examined with κ statistics. RESULTS: Twenty-eight pairs of EM samples were obtained from five patients. The diagnostic concordance rate of D&C and EM aspiration biopsy was 39.3% (κ value=0.26). Of the seven samples diagnosed as normal with D&C, three (42.8%) were diagnosed as normal by using EM aspiration biopsy. Of the eight samples diagnosed with endometrioid adenocarcinoma by using D&C, three (37.5%) were diagnosed with endometrioid adenocarcinoma by using EM aspiration biopsy. Of the 13 complex EM hyperplasia samples diagnosed with the D&C, five (38.5%) were diagnosed with EM hyperplasia by using EM aspiration biopsy. Of the samples obtained through EM aspiration, 46.4% were insufficient for histological evaluation. CONCLUSION: To evaluate the treatment responses of patients with early-stage EC treated with high dose oral progestin and LNG-IUS, D&C should be conducted after LNG-IUS removal.

Successful delivery after conservative resectoscopic surgery in a patient with a uterine tumor resembling ovarian sex cord tumor with myometrial invasion

Uterine tumor resembling ovarian sex cord tumors (UTROSCT) is an extremely rare type of uterine stromal neoplasm that exhibits prominent sex cord-like differentiation. The clinical characteristics of a UTROSCT are not fully understood. Most reported cases of UTROSCT were treated by hysterectomy with or without bilateral salpingo-oophorectomy; however, a few cases have been treated by only tumor resection in patients who had a strong desire to preserve their fertility. We present a case of UTROSCT with myometrial invasion, which resulted in a successful delivery after the patient was treated by resectoscopic surgery and conservation of the uterus, and a brief review of the literature.

Inguinal endometriosis in a patient without a previous history of gynecologic surgery

Endometriosis, defined as growth of endometrial stroma and glands outside the uterine cavity, is a chronic and recurrent disease that affects patients' quality of life. Ectopic endometrial tissue can proliferate at any location in the body, but the pelvic organs and peritoneum are the most frequent implantation sites. Among extrapelvic endometriosis, inguinal endometriosis is a very rare gynecologic condition usually associated with previous pelvic surgery. Endometriosis should be preoperatively distinguished from other inguinal masses using computed tomography, magnetic resonance imaging, or ultrasonography. Here, we report a case of right inguinal endometriosis in a patient with no previous history of gynecologic surgery; in addition, we have provided a brief review of relevant literature.

Clinical applications of levonorgestrel-releasing intrauterine system to gynecologic diseases

The levonorgestrel-releasing intrauterine system (LNG-IUS), originally designed for contraception, has since been applied to various gynecologic diseases. This article summarizes the current status of clinical applications of LNG-IUS to the treatment of gynecologic diseases such as heavy menstrual bleeding, endometriosis, leiomyoma, adenomyosis, endometrial hyperplasia, and early-stage endometrial cancer.

Intraoperative intraperitoneal chemotherapy with cisplatin in epithelial ovarian cancer / 부인종양

OBJECTIVE: To assess retrospectively the feasibility of intraoperative intraperitoneal (IP) chemotherapy with cisplatin in epithelial ovarian cancer. METHODS: IP chemotherapy during optimal staging surgery was performed in 10 patients who were diagnosed with primary epithelial ovarian cancers between April 2008 and February 2011. Cisplatin (70 mg/m2 in 1 L normal saline solution) was administered in the abdominal cavity for 24 hours postoperatively and then adjuvant chemotherapy was started 2-4 weeks after surgery. Perioperative toxicity of the combined treatment was evaluated until the initiation of postoperative adjuvant chemotherapy. RESULTS: A total of 23 adverse events were observed in 9 of 10 patients (grade 1, 7; grade 2, 13; grade 3, 3; grade 4, 0). In descending order of frequency, adverse events affected the gastrointestinal system (n=14), hematologic system (n=6), pulmonary system (n=2), and genito-urinary system (n=1). The adverse events did not affect adjuvant systemic chemotherapy schedules. One patient experienced disease recurrence in the liver 16 months after surgery. The remaining 9 patients have been well controlled by chemotherapy and/or observation during the follow-up period of 4 to 39 months after surgery. CONCLUSION: Intraoperative IP chemotherapy with cisplatin during surgical procedures is considered feasible for the treatment of primary epithelial ovarian cancer. Further studies, including long-term, prospective and comparative trials, are needed to validate the efficacy of this combined therapy.

Single-port access total laparoscopic hysterectomy in women with history of previous abdominal surgery / 대한산부인과내시경학회지

OBJECTIVE: The aim of the present study was to evaluate the impact of previous abdominal surgery on surgical outcomes of single-port access (SPA) total laparoscopic hysterectomy (TLH). METHODS: We reviewed the medical records of 111 women who underwent SPA-TLH at the Department of Obstetrics and Gynecology, CHA Gangnam Medical Center, CHA University between January 2010 and December 2010. Women were classified according to their history of previous abdominal surgery. RESULTS: Of 111 women undergoing SPA-TLH, 74 women (66.7%) without history of previous abdominal surgery and 37 women (33.3%) with history of previous abdominal surgery were classified. There was no significant difference in surgical outcomes including operative time, estimated blood loss, change in hemoglobin, uterine weight, perioperative complications, transfusion, and additional port insertion between two groups. CONCLUSION: In our experience, previous abdominal surgery has no significant impact on SPA-TLH.

Clinical experiences of the levonorgestrel-releasing intrauterine system in Korean women with adenomyosis / 대한산부인과내시경학회지

OBJECTIVE: To analyze the clinical experiences of patients who treated with levonorgestrel-releasing intrauterine system (LNG-IUS) for adenomyosis associated with dysmenorrhea and/or menorrhagia. METHODS: The LNG-IUS was inserted into 103 patients who were diagnosed with adenomyosis on ultrasound examination and suffered from dysmenorrhea or menorrhagia at CHA Gangnam Medical Center between January 2009 and December 2009. Symptomatic changes of dysmenorrhea and menorrhagia, side effects, and failure rates were evaluated, retrospectively. RESULTS: During the follow-up periods, dysmenorrhea was improved in 91.4% and menorrhagia was improved in 90.4% of patients. Most common side effects were prolonged vaginal spotting in 41 (39.8%), and expulsion of LNG-IUS in 32 (31.1%) patients. Six (5.7%) patients were premature removal of LNG-IUS and 9 (8.5%) patients were underwent hysterectomy. Overall 77 (74.8%) patients continued to use of LNG-IUS. CONCLUSION: The LNG-IUS is effective treatment option for management of dysmenorrhea and menorrhagia for patients with clinical diagnosis of adenomyosis. It seemed to be an alternative treatment method before hysterectomy.

The safety of conization in the management of adenocarcinoma in situ of the uterine cervix / 부인종양

OBJECTIVE: To evaluate the occurrence of residual or recurrent disease after conization for adenocarcinoma in situ (AIS) of the uterine cervix. METHODS: Medical records of 99 patients with a histologically diagnosis of AIS of the uterine cervix by conization between 1991 and 2008 were reviewed retrospectively. RESULTS: Seventy eight of 99 patients (78.8%) had negative and 18 (18.2%) had positive resection margins of the conization specimen, and 3 (3.0%) had unknown margin status. Of the 78 patients with negative margins, 45 underwent subsequent hysterectomy and residual AIS were present in 4.4% (2/45) of patients. Ten of the 18 patients with positive margins received subsequent hysterectomy and 3 patients (30%) had residual AIS. Twenty-eight patients had conservative treatment and during the median follow-up time of 23.5 months (range, 7 to 124 months), only one patient (3.6%) had recurrent AIS and was treated with a simple hysterectomy. Eight patients became pregnant after conization, 4 of them delivered healthy babies, one had a spontaneous abortion and 3 were ongoing pregnancies. CONCLUSION: Patients with positive resection margins after conization for AIS of the uterine cervix are significantly more likely to have residual disease. However, negative resection margin carries a lower risk for residual AIS, therefore conservative management with careful surveillance seems to be feasible in women who wish to preserve their fertility.

The effectiveness of a single preoperative dose of misoprostol during laparoscopic myomectomy / 대한산부인과내시경학회지

OBJECTIVE: To evaluate the effectiveness of single preoperative dose of misoprostol to reduce intraoperative hemorrhage during laparoscopic myomectomy. METHODS: We reviewed retrospectively the medical records of 148 patients who underwent laparoscopic myomectomy in Gangnam CHA Medical Center between January 2007 and December 2009 by single surgeon. Among them, 46 patients used preoperative transrectal misoprostol. One hundred two patients underwent laparoscopic myomectomy in conventional method without any preoperative agents. RESULTS: The two groups were similar in baseline characteristics. There was no significant difference in mean blood loss (misoprostol group: 203.3+/-181.8 mL vs. no agent group: 207.7+/-144.5 mL), operation time (misoprostol group: 113.3+/-28.2 min vs. no agent group: 113.4+/-31.5 min), and hemoglobin change (misoprostol group: 2.0+/-1.0 g/dL vs. no agent group: 1.9+/-1.0 g/dL). Two patients needed transfusion in misoprostol group whereas none in control group, but there was no statistical significance. CONCLUSION: A single preoperative dose of transrectal misoprostol cannot reduce bleeding during laparoscopic myomectomy.

Adenomatoid tumors of female genital tracts: An analysis of 195 cases / 대한산부인과학회지

OBJECTIVE: Adenomatoid tumors of female genital tracts are benign lesions derived from mesothelium, occurring most commonly during the reproductive years. The aim of this study was to evaluate the overall incidence of adenomatoid tumors in Korean women and to analyze the clinical characteristics. METHODS: One hundred and ninety five patients with adenomatoid tumors were found in a retrospective medical records review of pathologic reports for 44,984 benign uterine diseases at Cheil General Hospital, from January 1995 to April 2009. RESULTS: The overall incidence rate was 0.42% of all benign uterine disease. Among them, 149 patients received hysterectomy, and 46 patients received uterine conservative surgery. Main symptoms of the patients were pain (25.1%), bleeding (30.2%), and palpable mass (18.5%). Most common associated pathologies were leiomyoma (46.6%), adenomyosis (25.1%) and endometriosis (13.1%). Most of the diagnosis was made postoperatively. Among 46 patients with conservative treatment, 13 patients showed successful pregnancy outcome. No recurrence occurred during the follow up period. CONCLUSION: Adenomatoid tumors are associated with fibroids and tend to mimic them clinically, making pre-operative diagnosis difficult. The recurrence is rare even after conservative operation. Our data about this benign neoplasm may be helpful for counseling patients after operations.

Evaluation of recombinant adenovirus-mediated gene delivery for expression of tracer genes in catecholaminergic neurons / 대한해부학회지

Selective labeling of small populations of neurons of a given phenotype for conventional neuronal tracing is difficult because tracers can be taken up by all neurons at the injection site, resulting in nonspecific labeling of unrelated pathways. To overcome these problems, genetic approaches have been developed that introduce tracer proteins as transgenes under the control of cell-type-specific promoter elements for visualization of specific neuronal pathways. The aim of this study was to explore the use of tracer gene expression for neuroanatomical tracing to chart the complex interconnections of the central nervous system. Genetic tracing methods allow for expression of tracer molecules using cell-type-specific promoters to facilitate neuronal tracing. In this study, the rat tyrosine hydroxylase (TH) promoter and an adenoviral delivery system were used to express tracers specifically in dopaminergic and noradrenergic neurons. Region-specific expression of the transgenes was then analyzed. Initially, we characterized cell-type-specific expression of GFP or RFP in cultured cell lines. We then injected an adenovirus carrying the tracer transgene into several brain regions using a stereotaxic apparatus. Three days after injection, strong GFP expression was observed in the injected site of the brain. RFP and WGA were expressed in a cell-type-specific manner in the cerebellum, locus coeruleus, and ventral tegmental regions. Our results demonstrate that selective tracing of catecholaminergic neuronal circuits is possible in the rat brain using the TH promoter and adenoviral expression.

Pregnancy outcomes of heterotopic pregnancy / 대한산부인과학회지

OBJECTIVE: The purpose of this study was to evaluate the pregnancy outcomes of heterotopic pregnancy. METHODS: Retrospective analysis was done in 24 patients who were diagnosed as heterotopic pregnancy between January 2000 and April 2008. Patients' characteristics, risk factors, treatment methods and pregnancy outcomes were evaluated. RESULTS: A total of 24 patients were diagnosed as heterotopic pregnancy, all of these had undergone assisted reproductive technique. The mean age was 31.5 years and the mean gestational age at diagnosis was about 8 weeks. The most common etiology of infertility was tubal factor (54.2%). Four (16.7%) of the women had undergone ovulation induction, eighteen (75%) had undergone in vitro fertilization, but 2 patients (8.3%) had undergone assisted reproductive technique at other hospital and we didn't know the exact method. The most common of ectopic site was tube (75%), and 50% of ectopic sites were ruptured status at diagnosis. Three (12.5%) of 24 patients were diagnosed ectopic pregnancy after dilatation and evacuation due to missed abortion, 4 (16.7%) were diagnosed ectopic pregnancy and missed abortion, and 17 (70.8%) were diagnosed ectopic pregnancy and living intrauterine pregnancy at the time of diagnosis. Laparotomy was done in 3 patients (12.5%) and laparoscopy was done in 21 patients (87.5%). Among 17 patients who had normal intrauterine pregnancy, 12 (70.6%) delivered singletones, 2 (11.8%) delivered twins, but 3 (17.6%) patients were lost follow up. CONCLUSION: Heterotopic pregnancy should be considered in pregnant woman with abdominal pain or vaginal bleeding, although confirmed normal intrauterine pregnancy using ultrasonography at early gestational age, especially if the woman have treatment history for infertility. And early diagnosis and proper management are important.
