RESUMO
INTRODUCTION: This observation study aimed to differentiate between lobular endocervical glandular hyperplasia (LEGH) and gastric-type mucinous carcinoma (GAS) while evaluating the feasibility and efficacy of laparoscopic surgery in the preoperative diagnosis of cervical cystic lesions. METHOD AND MATERIAL: A retrospective study was conducted to evaluate the diagnostic process and laparoscopic surgical management of cervical cystic lesions suspected to be LEGH or GAS. Preoperatively and postoperatively, MRI, cytology, histology, tumor marker analysis, and surgical outcomes (blood loss during surgery, operative time) were assessed. Six individuals were selected based on magnetic resonance imaging (MRI) results indicating a preoperative suspicion of LEGH or GAS. These patients underwent laparoscopic surgical treatment without indications of malignancy based on preoperative histology or cytology. RESULTS: Initially, all individuals were suspected to have LEGH based on MRI findings. Postoperatively, two patients were diagnosed with LEGH, two with adenocarcinoma in situ (AIS) and minimal deviation adenocarcinoma (MDA), and two showed no notable findings on pathology (one diagnosed endometrioid carcinoma in endometrial tissue). Patients with malignancies exhibited longer surgical times and higher intraoperative blood loss. Preoperatively, no significant variation was observed in maximal lesion diameter between adenocarcinoma and LEGH. However, lesion diameter increased significantly over time in patients with GAS. CONCLUSION: Laparoscopic surgery demonstrated feasibility and provided crucial diagnostic and therapeutic outcomes, with no postoperative recurrence observed in cases of malignancy, despite the challenges associated with preoperative differentiation. These findings underscore the potential of laparoscopic surgery in enhancing both diagnostic accuracy and therapeutic efficacy for cervical cystic lesions, offering promise for improved patient outcomes and management strategies in clinical practice.
RESUMO
BACKGROUND: The oral gonadotropin-releasing hormone antagonist relugolix, which temporarily stops menstruation, is used to treat heavy menstrual bleeding, pelvic pressure, and low back pain in women with uterine fibroids. Treatment can also help women recover from low hemoglobin levels and possibly shrink the fibroids. However, evidence of preoperative use of relugolix before laparoscopic myomectomy is limited. Nevertheless, the treatment could reduce interoperative blood loss, decrease the risk of developing postoperative anemia, and shorten the operative time. Thus, we aim to test whether 12-week preoperative treatment with relugolix (40 mg orally, once daily) is similar to or not worse than leuprorelin (one injection every 4 weeks) to reduce intraoperative blood loss. METHODS: Efficacy and safety of preoperative administration of drugs will be studied in a multi-center, randomized, open-label, parallel-group, noninferiority trial enrolling premenopausal women ≥ 20 years of age, diagnosed with uterine fibroids and scheduled for laparoscopic myomectomy. Participants (n = 80) will be recruited in the clinical setting of participating institutions. The minimization method (predefined factors: presence or absence of fibroids ≥ 9 cm and the International Federation of Gynecology and Obstetrics [FIGO] type 1-5 fibroids) with randomization is used in a 1:1 allocation. Relugolix is a 40-mg oral tablet taken once a day before a meal, for 12 weeks, up to the day before surgery. Leuprorelin is a 1.88 mg, or 3.75 mg subcutaneous injection, given in three 4-week intervals during patient visits before the surgery. For the primary outcome measure of intraoperative bleeding, the blood flow is collected from the body cavity, surgical sponges, and collection bag and measured in milliliters. Secondary outcome measures are hemoglobin levels, myoma size, other surgical outcomes, and quality-of-life questionnaire responses (Kupperman Konenki Shogai Index and Uterine Fibroid Symptoms-Quality of Life). DISCUSSION: Real-world evidence will be collected in a clinical setting to use pre-treatment with an oral gonadotropin-releasing hormone antagonist to reduce intraoperative bleeding in women who undergo laparoscopic myomectomy. TRIAL REGISTRATION: jRCTs031210564 was registered on 19 January 2022 in the Japan Registry of Clinical Trials ( https://jrct.niph.go.jp ).

Twelve years after the first edition of The Guideline for Gynecological Practice, which was jointly edited by The Japan Society of Obstetrics and Gynecology and The Japan Association of Obstetricians and Gynecologists, the 5th Revised Edition was published in 2023. The 2023 Guidelines includes 5 additional clinical questions (CQs), which brings the total to 103 CQ (12 on infectious disease, 30 on oncology and benign tumors, 29 on endocrinology and infertility and 32 on healthcare for women). Currently, a consensus has been reached on the Guidelines, and therefore, the objective of this report is to present the general policies regarding diagnostic and treatment methods used in standard gynecological outpatient care that are considered appropriate. At the end of each answer, the corresponding Recommendation Level (A, B, C) is indicated.

Pyomyoma is an extremely rare complication, defined as an infection of a uterine leiomyoma. We describe two cases of pyomyoma that were initially considered to be tubo-ovarian abscesses but were later diagnosed as pyomyomas and managed with laparoscopic surgery. Case 1 was a 26-year-old nulliparous woman who was previously diagnosed with bilateral endometriomas and presented to the hospital with lower abdominal pain. Magnetic resonance imaging revealed bilateral endometrial cysts and a 4-cm mass consistent with a tubo-ovarian abscess. The patient experienced continuous pain, and the cyst in the left adnexa enlarged; thus, laparoscopic surgery was performed. The cystic tumor in her uterus contained purulent fluid. Therefore, an abscess in the degenerative subserous myoma was diagnosed. Case 2 was a 47-year-old nulliparous woman who had undergone total mastectomy and postoperative radiotherapy for breast cancer. She was undergoing hormone therapy when she presented to the hospital with lower abdominal pain, fever, and increased inflammatory markers. Computed tomography revealed a 7-cm tumor with rim enhancement in her left adnexa; therefore, a tubo-ovarian abscess was suspected. After admission, drainage was performed under transvaginal ultrasound guidance, and antibiotics were administered. However, these treatments did not relieve her abdominal pain. Emergency laparoscopic surgery was performed, and intraoperative findings demonstrated an abscess in the degenerative subserous myoma of the uterus with normal adnexa. Laparoscopic hysterectomy and bilateral salpingectomy were performed. Laparoscopic surgery was effective for both patients. Delayed diagnosis of pyomyoma can result in serious complications. Timely surgery with concomitant antibiotic treatment may facilitate good outcomes.
RESUMO
INTRODUCTION: We aimed to identify the characteristics of cases involving postoperative bleeding after laparoscopic gynecologic surgery, and to clarify the optimal cutoff value of postoperative drainage and vital sign trends for predicting the need for re-laparoscopy. METHODS: Of 6366 patients with gynecologic benign pathologies who underwent laparoscopic surgery at our institution between 2009 and 2018, 13 (0.2%) required re-laparoscopy for postoperative bleeding. After reviewing the perioperative course in the re-laparoscopy group, we examined the postoperative total drainage volume (mL), drainage flow rate (mL/h), and vital sign trends in the re-laparoscopy group (n = 13) and among patients with substantial drainage volume ≥300 mL at 12 hours postoperatively but who did not need re-laparoscopy (observation group, n = 107). RESULTS: In the re-laparoscopy group, initial laparoscopic surgery included uterine surgery (myomectomy, n = 7; hysterectomy, n = 1), adnexal surgery (n = 3), and uterine plus adnexal surgery (n = 2). Postoperative bleeding sites included the uterine wound (n = 6), adnexal wound (n = 5), umbilical trocar site (n = 1), and mesentery (n = 1). The re-laparoscopy and observation groups did not differ regarding initial surgical characteristics or postoperative vital sign trends. For distinguishing between the re-laparoscopy and observation groups, the drainage flow rate was superior to total drainage volume. Continuous excessive drainage (flow rate >50 mL/h) at 3 hours postoperatively was associated with a remarkably increased risk for re-laparoscopy (odds ratio, 40.07; 95% confidence interval, 5.44 to 1776.41, P < 0.001). CONCLUSION: In cases with continuous excessive drainage later than 3 hours postoperatively (flow rate >50 mL/h) should be considered for exploratory re-laparoscopy to enable prompt diagnosis and intervention.

AIM: The aim of the study was to assess the incidence of postoperative adhesion by baseball running suture using barbed suture (BS) in laparoscopic myomectomy in comparison with sutures using an absorbable thread. METHODS: Two hundred fifteen patients who underwent second-look laparoscopy (SLL) 6 months after laparoscopic myomectomy at our hospital between 2010 and 2014 were retrospectively reviewed. The incidence, numbers, types, and extent of adhesions were evaluated according to the more comprehensive adhesion scoring method. Propensity score matching (PS) (1:1) between the groups was performed by using the diameter of the largest myoma, the number of enucleated myomas, and the type of adhesion barrier. RESULTS: Running baseball sutures and running sutures were applied to 28 and 187 patients with unidirectional BS and absorbable thread, respectively, to close the incised serosal wounds enucleating largest myomas during laparoscopic myomectomy. After PS matching for the patients, surgical findings and the incidence of postoperative wound adhesions were compared between the groups, including 22 patients each. The surgical findings were similar between the groups, except for the total surgical duration and blood loss (medians), which were significantly shorter and lower in the BS group than in the absorbable thread group (70 vs. 100 min; p = 0.01, 50 vs. 100 mL; p = 0.02). Regarding findings of SLL, no significant differences in the incidence of postoperative wound adhesions were found between the groups (BS, 4/22 [18.2%] versus absorbable thread, 8/22 [36.4%]; p = 0.31). CONCLUSION: Our data indicated that the incidence of postoperative adhesion following the use of BS for wound closure in laparoscopic myomectomy was similar to that following the use of conventional suture.

PURPOSE: To compare the effects of preoperative dienogest (DNG) and gonadotropin-releasing hormone (GnRH) agonist administration on the improvement of preoperative symptoms and surgical outcomes in patients who underwent laparoscopic cystectomy for ovarian endometriomas. METHODS: Seventy patients who were scheduled for laparoscopic surgery were enrolled in the study. They were divided into two groups: 35 patients who received DNG for 4 months preoperatively (group D) and 35 patients who received low-dose sustained-release goserelin acetate for 4 months preoperatively (group G). Preoperative outcomes, including pain score associated with endometriosis, using the numerical rating scale (NRS), adverse events of hormonal therapy and Kupperman index (KI) before and after treatment, surgical outcomes including total surgical duration and blood loss, and postoperative recurrence of endometrioma were compared between the two groups. RESULTS: Regarding preoperative symptoms, NRS and KI at 4 months after preoperative hormonal therapy were significantly lower in group D than in group G (NRS, 5.3 ± 5.5 vs. 2.7 ± 3.9; P = 0.01; KI, 16.0 ± 11.0 vs. 9.2 ± 7.6; P = 0.006). Regarding adverse events, the incidence of hot flashes was significantly lower in group D than in group G (P < 0.001). Meanwhile, the incidence of breast pain and metrorrhagia was significantly higher in group D than in group G (P = 0.04 and P < 0.001, respectively). The total surgical duration and blood loss were not significantly different between the groups. At 12 months after surgery, ovarian endometrioma did not recur in either group. CONCLUSION: Preoperative administration of DNG is more valuable for patients with endometriosis and scheduled for laparoscopic surgery to improve symptoms with good efficacy and tolerability than the administration of GnRH agonist.

AIM: Since 2014, Japan Society of Gynecologic and Obstetric Endoscopy and minimally invasive therapy (JSGOE) conducted a nationwide survey on gynecologic endoscopic surgery. We aimed to evaluate the current status and complications associated with endoscopic surgery by Japan gynecologic and obstetric endoscopy-database registry system (JOE-D). METHODS: Electrical medical records concerning the endoscopic surgery were generated from the daily use of reporting system. The subjects were all patients who underwent gynecologic endoscopic surgery. In addition to assessment of actual numbers, diagnosis, and operative methods, adverse events were registered. RESULTS: Total 203 970 patients performed laparoscopic, hysteroscopic and falloposcopic surgery for 3 years, 2014-2016. The numbers of endoscopic surgeries conducted in 2016 were increased more than 67 000, 13 000 or 450 cases, respectively. Incidence rates of complications involving these three types of surgeries in each year were approximately 3.1%. Incidences of intraoperative complications were relatively high in malignant diseases, laparoscopic-assisted vaginal hysterectomy (LAVH) and myomectomy (LAM). In total laparoscopic hysterectomy/laparoscopic hysterectomy (TLH/LH) performed from 2014 to 2016, ureteral injury as intra and postoperative complication occurred in 0.35%. In the past 3 years, the rates of vascular injury, urinary tract, and bowel injury as intraoperative complications caused by laparoscopic surgery were approximately 0.1%. In the hysteroscopic surgery, the rates of total intra- and postoperative complications were 0.78%. CONCLUSION: We exhibited the current status by the nationwide survey of gynecologic endoscopic surgery all over Japan. Severe intra or postoperative complications were identified over the 3 years at a rate of 0.04%.

Upon breaching of the endometrial surface epithelium, the implanting embryo embeds in the decidualizing stroma. Retinoic acid (RA), a metabolite of vitamin A, is an important morphogen during embryonic and fetal development, although the role of the RA pathway in the surrounding decidual cells is not understood. Here we show that decidual transformation of human endometrial stromal cells (HESCs) results in profound reprogramming of the RA signaling and metabolism pathways. Differentiating HESCs downregulate the intracellular carrier proteins CRABP2 and FABP5, responsible for transfer and binding of RA to the nuclear receptors RAR and PPARß/δ, respectively. Furthermore, the expression of RAR, the receptor that mediates the pro-apoptotic effects of RA, was also inhibited. By contrast, PPARß/δ, which transduces the differentiation responses of RA, was upregulated. Decidualization was also associated with increased expression of retinol-binding protein 4 (RBP4) and various enzymes involved in the metabolism of RA and its precursor, retinaldehyde (Rald), including CYP26A1, DHRS3, and RDH12. Exposure of differentiating HESCs to RA or Rald reversed the inhibition of the CRABP2-RAR pathway, perturbed the expression of decidual marker genes and triggered cell death. Taken together, the data demonstrate that decidualizing HESCs silence RA signaling by downregulating key cytoplasmic binding proteins and by increasing retinoid metabolism. However, excessive RA exposure is toxic for decidual cells and triggers a response that may lead to pregnancy failure.

Uterine compression suturing is a relatively easy and effective way of hemostasis during cesarean section and is becoming widely accepted. However, complications such as necrosis or synechiae have been reported. We firstly report a case of laparoscopic removal of vertical compression sutures and discuss its benefits and improvements to be made. This case report is of a 32-year-oId woman with placenta previa who received uterine vertical compression sutures for controlling massive bleeding during cesarean section. Because she complained of unbearable pelvic pain, laparoscopic compression suture removal was performed. Her pain was relieved after the threads were removed, suggesting that the compression sutures were the cause of her pelvic pain due to uterine ischemia. Although the risks of reoperation during the early postpartum period still exist, compression suture thread removal should be considered in cases of suspected uterine ischemia.
RESUMO
BACKGROUND/AIMS: Despite the benefits of laparoscopic surgery, which is being performed with increasing frequency, complications that do not occur during laparotomy are sometimes encountered. Such complications commonly occur during the initial trocar insertion, making this a procedural step of critical importance. METHODS: In 2002, we experienced, upon initial trocar insertion, a serious major vascular injury (MVI) that led to hemorrhagic shock, and we thus modified the conventional closed entry method to an approach that we have found to be safe. We began developing the method by first measuring, in a patient undergoing laparoscopic cystectomy, the distance between the inner surface of the abdominal wall and the anterior spine when the abdominal wall was lifted manually for trocar insertion and when it was lifted by other methods, and we determined which method provided the greatest distance. We then devised a new approach, summarized as follows: The umbilical ring is elevated with Kocher forceps. The umbilicus is everted, and the base is incised longitudinally. This allows penetration of the abdominal wall at its thinnest point, and it shortens the distance to the abdominal cavity. A bladeless trocar (Step trocar) is used to allow insertion of the Veress needle. We began applying the new entry technique in July 2002, and by December 2014, we had applied it to 9676 patients undergoing laparoscopic gynecology surgery. RESULTS: All entries were performed successfully, and no MVI occurred. The umbilical incision often resulted in an umbilical deformity, but in a questionnaire-based survey, patients generally reported satisfaction with the cosmetic outcome. CONCLUSION: A current new approach provides safe outcome with a minor cosmetic problem.
RESUMO
BACKGROUND: Ovarian endometriomas affect a substantial proportion of women of reproductive age who may have a potential risk of diminished ovarian reserve (DOR) after ovarian cystectomy. Here, we investigated the risk factors for pre-surgical DOR in patients with ovarian endometriomas and for DOR after laparoscopic ovarian cystectomy for endometriomas and evaluated the feasibility of the pre-surgical prediction of post-surgical DOR based on the Bologna criteria. METHODS: A total of 143 patients with ovarian endometriomas who underwent laparoscopic cystectomy from January 2009 to May 2015 at our hospital were prospectively enrolled and evaluated. Serum anti-Müllerian hormone (AMH) concentrations were measured pre-surgically and at 3 and 6 months after surgery. In accordance with the Bologna criteria, the patients whose AMH concentrations were <1.1 ng/mL before surgery and 3 or 6 months after surgery were classified into pre- and post-surgical adverse DOR (aDOR) groups, respectively. RESULTS: Thirty-one (21.7 %) of 143 patients were classified as pre-surgical aDOR. Patient age and serum follicle-stimulating hormone level were significantly positively correlated with pre-surgical aDOR [odds ratios (ORs), 1.26 and 1.16; p < 0.001 and p = 0.003, respectively]. Among the remaining 112 patients, 38 patients (33.9 %) had post-surgical aDOR 3 and 6 months after surgery. Bilateral cystectomy was positively correlated with post-surgical aDOR (at 3 months: OR, 4.7; p = 0.001; at 6 months: OR, 3.71; p = 0.006); conversely, pre-surgical serum AMH concentrations were negatively correlated with post-surgical aDOR (at 3 months: OR, 0.65; p = 0.005; at 6 months: OR, 0.43; p < 0.001). The optimal cut-off point of pre-surgical AMH concentrations for predicting aDOR at 3 and 6 months in the patients undergoing unilateral cystectomy was 2.1 ng/mL. In contrast, the optimal cut-off points at 3 and 6 months in the patients undergoing bilateral cystectomy were 3.0 and 3.5 ng/mL, respectively. CONCLUSIONS: Our data suggest that the pre-surgical serum AMH concentrations and bilateral cystectomy are significant factors for the risk of aDOR following surgery and that predicting post-surgical aDOR according to the Bologna criteria could be feasible using pre-operative measurements of serum AMH concentrations.

AIM: The aim of this study was to assess the efficacy of a minimal ovarian stimulation involving combined clomiphene citrate (CC) and estradiol (E2) administration for poor responders with diminished ovarian reserve (DOR). MATERIAL AND METHODS: In this case-control study, we recruited 41 consecutive hypergonadotropic poor responders (69 cycles) who met Bologna-criteria and had experienced cancellation of oocyte retrieval. In 10 (20 cycles), 11 (21 cycles) and 20 patients (28 cycles) between 2012 and 2014, follicular development was induced using an E2 cycle, CC cycle and CC + E2 cycle, respectively. After confirmation of high follicle-stimulating hormone levels (15-40 mIU/ml) at menstrual day 3, DOR patients were treated with oral E2 of 1.0 mg/day, CC of 100 mg/day, or both CC and E2 continuously, until ovulation induction. Two days later, we transvaginally aspirated the follicles, performed in vitro fertilization, and cryopreserved the cleavage embryos. One warmed embryo was transferred into the uterus during the hormone replacement cycles. RESULTS: For the E2, CC, and CC + E2 cycles, the median patient age was 41 years in all groups, and the serum anti-Müllerian hormone levels were 0.2 ± 0.3, 0.4 ± 0.4, and 0.2 ± 0.3 ng/mL, respectively (P = 0.258); follicular development failure rates were 50.0%, 19.0%, and 3.6%, respectively (P < 0.001); numbers of retrieved oocytes (/cycle) were 0.5 ± 0.6, 0.8 ± 0.7, and 1.2 ± 1.1, respectively (P = 0.033); and clinical pregnancy rates (/cycle) were 5.0%, 4.8%, and 10.7%, respectively (P = 0.725). CONCLUSION: CC + E2 administration for the patients with DOR was effective with a lower cancellation rate of oocyte retrieval and a higher number of retrieved oocytes.

OBJECTIVE: To investigate the incidence of port-site adhesions following use of radially expanding trocars (RETs) at laparoscopic myomectomy by observation via second-look laparoscopy (SLL). METHODS: In a retrospective study, data from patients who underwent SLL after laparoscopic myomectomy between January 2007 and June 2012 at Juntendo University Hospital, Tokyo, were assessed for the incidence of port-site adhesions forming below RET incisional scars when fascial and peritoneal defects had not been closed. RESULTS: During the study period, 554 patients underwent SLL, and 2176 incisional scars were examined. Adhesions were detected in 15 patients (2.8%); thus, the incidence of port-site adhesions under scars was 0.7% (15/2176). Among these 15 patients, the wounds with adhesions were located as follows: 6 (1.1%) under the umbilical scar, 5 (0.9%) under the right lower abdominal scar, 2 (0.4%) under the left upper abdominal scar, and 2 (0.4%) under the left lower abdominal scar. According to multiple regression analysis, the duration of laparoscopic myomectomy was positively associated with port-site adhesions (odds ratio, 1.79; 95% confidence interval, 1.09-2.94; P=0.02). CONCLUSION: The present data suggest that the incidence of port-site hernias and adhesions under RET incisional scars is low despite the non-closure of fascial and peritoneal defects.

BACKGROUND: Myomectomy is now often performed laparoscopically rather than by laparotomy to alleviate the risk of postoperative adhesions and reduce postoperative pain. However, intracorporeal knot-tying under direct laparoscopy is difficult and requires proficiency. We conducted a retrospective study comparing the results of a long unidirectional barbed suturing technique (with V-Loc180 suture) and the results of conventional suturing as applied to laparoscopic myomectomy. METHODS: In women who underwent laparoscopic myomectomy in our university hospital between January 2011 and April 2013, uninterrupted suturing of 2 or more layers was performed. These women were divided into 2 groups according to the method of suturing: those in whom standard absorbable sutures were used (group P, n =42) and those in whom our suturing technique was used (group V, n =41). Patient characteristics and surgical variables were compared between the 2 groups. RESULTS: No significant between-group difference was observed in age (p = .975), body mass index (p = .778), GnRHa administration (p = .059), intraoperative vasopressin dose (p = .364), intraoperative blood loss (73.8 ± 64.1 vs. 59.3 ± 54.0 mL, respectively; p = .199), myoma mass (212.6 ± 133.3 vs. 208.3 ± 198.4 g, respectively; p = .134), ΔHb (p = .517), or postoperative hospital stay (p = .314). Operation time (mean ± SD) was significantly shorter for group V (71.2 ± 22.9 minutes; range, 28.0-110.0 minutes; p < .001) than for group P (94.4 ± 27.2 minutes; range, 53.0-165.0 minutes). No patient required intraoperative transfusion or conversion to laparotomy. CONCLUSIONS: Our suturing technique exploits the features of unidirectional barbed sutures and can be used in the same way as the conventional method when performing continuous suturing for laparoscopic myomectomy. Our data suggest that operation time can be reduced by as much as 25% with this new technique.

OBJECTIVE: We conducted a single-center study to evaluate the usefulness of the magnetic resonance (MR) imaging jelly method for diagnosing endometriosis-associated adhesions in the Pouch of Douglas. METHODS: Thirty women with menstrual pain, dyspareunia, and chronic pelvic pain were enrolled in the study. All had been scheduled for laparoscopic surgery on the basis of pelvic and/or ultrasonographic (US) evaluation. All underwent MR imaging both with and without application of US jelly to the vagina and rectum. The images were compared and analyzed postsurgically in a random and blinded fashion by a radiology specialist and a radiology fellow. The radiologists' interpretations of the images were compared to the surgical findings recorded on DVDs. RESULTS: Adhesions in the Pouch of Douglas were found in 21 patients. The sensitivity and specificity of MR imaging without jelly administration were 85.7% and 55.6%, respectively, for the specialist and 81.0% and 55.6%, respectively, for the fellow; with jelly administration, values were 95.2% and 88.9% for the specialist and 90.5% and 66.7% for the fellow. Opacity produced by the jelly increased the sensitivity and specificity for both radiologists. CONCLUSION: The MRI jelly method is a potentially useful, beneficial, and simple approach for diagnosing Pouch of Douglas adhesions.

The myoma pseudocapsule (MP) is a fibro-vascular network rich of neurotransmitters, as a neurovascular bundle, surrounding fibroid and separating myoma from myometrium. We investigated the distribution of the opioid neuropeptides, as enkephalin (ENK) and oxytocin (OXT), in the nerve fibers within MP and their possible influence in human reproduction in 57 women. An histological and immunofluorescent staining of OXT and ENK was performed on nerve fibers of MP samples from the fundus, corpus and isthmian-cervical regions, with a successive morphometric quantification of OXT and ENK. None of the nerve fibers in the uterine fundus and corpus MPs contained ENK and the nerve fibers in the isthmian-cervical region demonstrated an ENK value of up to 94 ± 0.7 CU. A comparatively lower number of OXT-positive nerve fibers were found in the fundal MP (6.3 ± 0.8 CU). OXT-positive nerve fibers with OXT were marginally increased in corporal MP (15.0 ± 1.4 CU) and were substantially higher in the isthmian-cervical region MP (72.1 ± 5.1 CU) (p < 0.01). The distribution of OXY neurofibers showed a slight into the uterine corpus, while are highly present into the cervico-isthmic area, with influence on reproductive system and sexual disorders manifesting after surgical procedures on the cervix.

We demonstrate the feasibility of single-incision laparoscopic surgery (SILS) by using a novel monopolar cautery and a technique based on conventional multiport laparoscopic surgery in a patient with Juvenile cystic adenomyoma (JCA). A 20-year-old woman with severe dysmenorrhea, and a 3-cm uterine lesion was diagnosed with JCA. 70 cm of absorbable string tied to the tumor parenchyma was used to extract the tumor. The ends of the strings were positioned extracorporeally and the intra-abdominal parts of the strings adjacent to the anchored tumor were grasped by a laparoscopic needle holder for clarifying the incision line surrounding the tumor. The lesion was completely excised using a single-use articulating hook with monopolar cautery, and the hysterotomy site was sutured using barbed string. No complications occurred intraoperatively, and dysmenorrhea had significantly improved three months after surgery. SILS for JCA is a feasible and minimally invasive surgery for women desiring esthetic benefit.

OBJECTIVE: To demonstrate the feasibility of minimally invasive surgery using a novel optical device to treat large benign ovarian cysts and to compare the safety of the procedure with that of conventional laparoscopically assisted multiport extracorporeal cystectomy. STUDY DESIGN: Twenty-one patients with large benign ovarian cysts underwent laparoscopically assisted extracorporeal ovarian cystectomy via a single suprapubic incision using a novel 10-mm rigid laparoscope with an adjustable direction of view and a multiport device, between October 2010 and July 2012. The surgical outcomes were retrospectively compared between these patients (Group A) and 32 patients who underwent the conventional 3-port laparoscopically assisted extracorporeal procedure between January 2009 and September 2010 (Group B). Data were statistically analyzed using the Mann-Whitney U-test or Fisher's exact test. RESULTS: None of Group A required conversion to conventional multiport laparoscopy. The total duration of surgery, elapsed time between skin incision and the start of pneumoperitoneum, and time required for intra- and extra-corporeal manipulations did not significantly differ between the groups. The time required for skin closure, however, was significantly decreased in Group A compared with Group B (13.0 ± 3.5 vs. 20.2 ± 4.8 min, P=0.005). The volume of blood loss and postoperative blood findings were similar to those associated with the conventional procedure. Postoperative visual analog pain scales at 3h were significantly lower in Group A than in Group B (3.7 ± 2.6 vs. 4.8 ± 2.0, P=0.04). Postoperative complications did not arise after either procedure. CONCLUSION: Laparoscopically assisted extracorporeal cystectomy via a single suprapubic incision is a feasible and safe alternative to conventional multiport cystectomy for treating large benign ovarian cysts.

BACKGROUND: For fertility preservation of women patients scheduled to undergo chemotherapy or radiotherapy, unilateral oophorectomy was performed, and the ovary was cryopreserved. METHODS: Two-port surgery was conducted in 3 patients, and single-port surgery using a single-incision laparoscopic surgery port in 3. An 18-G Cathelin needle equipped with a syringe was directly inserted transabdominally to reach the small follicle on the ovarian surface; then, follicular fluid was recovered by aspiration through the syringe as with in vitro fertilization procedures, and immature oocytes were collected from the resulting culture medium under microscopy and cryopreserved. Vitrification of the ovarian tissue was performed using the cryotissue method. RESULTS: The operative time and estimated blood loss were 39.7 minutes (17-57) and 8.6 mL (2-20), and the numbers of ovarian cortical tissues and immature oocytes collected were 10.1 (5.5-15) and 16.3 (0-36), respectively. CONCLUSIONS: It is suggested that fertility preservation operations before chemotherapy or radiotherapy can be safely done using reduced-port surgery.
