Postoperative administration of dienogest for suppressing recurrence of disease and relieving pain in subjects with ovarian endometriomas.

To assess the effect of dienogest on recurrence of ovarian endometriomas and severity of pain after laparoscopic surgery, a retrospective study of 81 patients was performed at three institutions in Osaka, Japan. Patients had a six-month minimum follow-up after laparoscopic surgery for ovarian endometriomas performed between June 2012 and August 2014. Patients who chose to receive 2 mg dienogest daily and those who were managed expectantly postoperatively were included. Recurrence was defined as the presence of endometriomas of more than 2 cm. A visual analog scale (VAS) was used to score the intensity of pelvic pain. The cumulative recurrence rate and absolute VAS score changes between the baseline and at 6, 12, 18 and 24 months after the start of administration were evaluated in both groups. The recurrence rate was 16.5% and 24.0% in the expectant management group at 12 and 24 months, respectively. No recurrences occurred in the dienogest treatment group. The rate of VAS score reduction was significantly higher in the dienogest than in the expectant management group. Dienogest is effective on the recurrence of ovarian endometrioma and relieving pelvic pain after laparoscopic surgery.

Assessment of age-specific safety of laparoscopic surgery in elderly patients with ovarian tumors.

AIM: We assessed the age-specific safety of laparoscopic surgery in elderly patients with ovarian tumors. MATERIAL AND METHODS: We performed a retrospective analysis of 55 elderly patients treated by laparoscopic salpingo-oophorectomy under the diagnosis of an ovarian tumor between January 2009 and December 2014. We divided patients into three groups: "young-elderly" (aged 65-74), "old-elderly" (aged 75-84), and "super-elderly" (aged 85-105) and assessed clinical characteristics, surgical results and postoperative course. Statistical significance of categorical variables was examined by the Student's t-test, Mann-Whitney U test, or Fisher's exact test. Multiple regression analysis was used for multivariate analysis. RESULTS: Of a total of 55 patients who underwent laparoscopic surgery, there were 36 patients in the young-elderly group, 17 in the old-elderly group, and two in the super-elderly group. Statistical analysis was performed between the young-elderly and the old-elderly groups because of the small number in the super-elderly group. More frequent comorbidities were found in the patients in the old-elderly than in the young-elderly group (Fisher's exact test, P = 0.007). There were no significant differences in operative time, estimated blood loss and postoperative hospital stay between the young-elderly and old-elderly groups. Intraoperative complications only occurred in the young-elderly group. Postoperative complications occurred in all groups. CONCLUSIONS: Although patients in the old-elderly group had a significantly higher risk for surgery, they had equivalent surgical results to the young-elderly group for laparoscopic salpingo-oophorectomy.

Comparative Study of Postoperative Analgesic Effects of Intraoperative Levobupivacaine Local Infiltration Anesthesia and Transversus Abdominis Plane Block Following Gynecologic Laparoscopy.

Objectives: We aim to assess the postoperative analgesic effect of intraoperative levobupivacaine local infiltration anesthesia (LA) and transversus abdominis plane (TAP) block in gynecologic laparoscopy. Materials and Methods: We conducted a retrospective analysis on the data of 260 patients treated by gynecologic laparoscopy (adnexal surgery, hysterectomy, and myomectomy) between January 2019 and December 2020 at Minoh City Hospital, Osaka Japan. Patients were divided into two groups: intraoperative LA group and TAP block group. We assessed clinical characteristics, surgical results, postoperative numerical rating scale (NRS) pain scores, and the frequency of analgesic use up to 24 h after surgery in overall and by each type of surgery. Pearson's χ2 test, Fisher's exact test, and Wilcoxon/Kruskal-Wallis test were used for statistical analysis. Multiple regression analysis was used for multivariate analysis. Results: NRS pain score was statistically significantly higher in the LA group than in the TAP group 1 h after surgery in overall (P = 0.04), with NRS difference of 0.4 which was not clinically significant. No significant differences were observed in NRS pain scores at 3, 6, 12, and 24 h after surgery or in the frequency of analgesic use up to 24 h after surgery in overall and by type of surgery. Endometriosis was associated with increased postoperative pain at 1 h after surgery in adnexal surgeries (P = 0.04) and suggestive for all surgeries. Younger age was related to more frequency of analgesic use up to 24 h after surgery in overall, adnexal surgeries, and hysterectomy. Conclusion: Intraoperative levobupivacaine LA may have similar postoperative analgesic effects as TAP block in gynecologic laparoscopy.

Usefulness of Disposable Skin Biopsy Punch for Cervical Occlusion after Cervical Conization.

Cervical occlusion is a rare but serious complication after conization of the uterine cervix. We report on a 69-year-old woman with cervical intraepithelial neoplasia (CIN) 2, who successfully underwent follow-up biopsy of an occluded cervical canal after conization using a disposable skin biopsy punch. The disposable skin biopsy punch was inserted into a slight dimple, which was considered a uterine os, in the direction of the cervical canal, and a sample of tissue was obtained from the occluded portion. This procedure was performed without anesthesia and was completed uneventfully. Histological examination of the excised tissue revealed CIN 3. In addition, the procedure resulted in recanalization of the occluded cervical canal. The occlusion was limited in the external portion of the cervical os and attributed to adhesion of scar tissue during the healing process. Our experience suggests that a disposable skin biopsy punch can be used for follow-up biopsy and recanalization in patients with cervical occlusion after conization as a less invasive approach.

Influences of Total Laparoscopic Hysterectomy According to Body Mass Index (Underweight, Normal Weight, Overweight, or Obese).

STUDY OBJECTIVE: The aim of this study is to evaluate the effect of body mass index (BMI) on laparoscopic hysterectomy outcomes. DESIGN: This was retrospective study. SETTING: Minoh City Hospital, Japan. MATERIALS AND METHODS: Between January 1, 2014, and June 30, 2017, 183 patients underwent total laparoscopic hysterectomy (TLH) at our institution. INTERVENTION: Patients who underwent TLH were grouped according to BMI, as follows: underweight group (BMI <18.5 kg/m2), normal-weight group (18.5 ≤BMI <25 kg/m2), overweight group (25 ≤BMI <30 kg/m2), and obese group (BMI ≥30 kg/m2). MEASUREMENTS AND MAIN RESULTS: Information on patients' clinical characteristics and surgical results were collected retrospectively by medical record review. The severity of complications was graded according to the Clavien-Dindo classification. We assessed clinical characteristics, surgical results, and the perioperative complications in each BMI group. Surgical results included operation time, nonsurgical operating room time estimated blood loss, uterine weight, and postoperative hospital stay. Compared with the normal-weight group, the obese group had significantly more complications (P = 0.012) and longer operation time (P = 0.04). The underweight and overweight groups did not have significantly different surgical results than the normal-weight group. CONCLUSION: Underweight and overweight patients had no significant differences in surgical results, compared with patients of normal weight. Obese patients had significantly longer operation times and more perioperative complications than patients with normal weight. Laparoscopic hysterectomy has burdens and risks for obese patients. Our results suggest that appropriate weight control may decrease the risk of surgery for obese patients.

Broad ligament hernia successfully repaired by single-incision laparoscopy: A case report.

A 52-year-old woman with a history of two parturitions presented with lower abdominal pain. Multi-detector CT of the abdomen showed discontinuity of the sigmoid colon near the broad ligament on the left side. We assigned a provisional diagnosis of an internal hernia progressing through a defect in the broad ligament. SILS revealed a total broad ligament defect on the left side but no signs of ischemic, necrotic bowel. We successfully repaired the broad ligament defect with suturing. At the 2-month follow-up, the patient remained well with no signs of recurrence. This case appears to be the first report of a broad ligament hernia successfully diagnosed and repaired by SILS.

Transumbilical extraction of 151-300-g myomas without morcellator versus conventional laparoscopic myomectomy with power morcellator.

STUDY OBJECTIVE: The aim of this study was to compare the surgical outcomes, particularly the specimen retrieval time, between two methods of laparoscopic myomectomy: transumbilical retrieval of the myoma without a morcellator and conventional retrieval of the myoma using a power morcellator via the left lower quadrant. DESIGN: Retrospective study. SETTING: Public hospital. PATIENTS: Seventy-four women undergoing laparoscopic myomectomy. INTERVENTIONS: Laparoscopic myomectomy followed by myoma retrieval via transumbilical extraction or electric motorized morcellator extraction. MEASUREMENTS AND MAIN RESULTS: Seventy-four patients undergoing laparoscopic myomectomy followed by myoma retrieval via transumbilical extraction or electric motorized morcellator extraction were studied. Significant differences were observed in the average weight of the retrieved myomas between the transumbilical and morcellator groups (141.0 vs. 262.8 g, respectively; p < 0.001). Therefore, we chose 27 patients whose total specimen weight was 151-300 g; 13 patients were in the transumbilical extraction group and 14 were in the electric motorized morcellator group. No significant differences were observed in patient characteristics between the two groups. The operative time, blood loss volume, and myoma retrieval time were similar between the two groups. CONCLUSION: Laparoscopic myomectomy with transumbilical extraction for myoma retrieval is a feasible method for specimens weighing up to 300 g.
