Aim: Postlaparoscopic shoulder pain (SP), mainly caused by pneumoperitoneum with CO 2 , sometimes suffers patients. This study was aimed to analyze the backgrounds of SP after gynecologic laparoscopy to clarify the risk of SP., Methods: We analyzed answers of questionnaire about the degree of SP from 696 patients undergoing gynecologic laparoscopic surgery since 2014-2018. The questionnaire asks the degree of SP with numeric rating scale from 0 to 10, before and 3 days after operation. We defined cases in which postoperative score elevated more than three compared to preoperative score as SP(+). Analyzed backgrounds were age, parity, body mass index, operative method, operative duration and amount of hemorrhage. Statistics was performed by Fisher exact analysis as univariate analysis, and with logistic regression as multivariate analysis. All laparoscopic surgeries were performed under 10-12 mmHg in pressure of pneumoperitoneum with CO 2 ., Results: Univariate analysis revealed categories 'less than 50 years old', and 'over 2 h' and 'over 3 h' in operative duration resulted significant high rate of SP(+). For these three factors, multivariate analysis resulted that "less than 50 years old' and 'over 3 h in operative duration' were significantly high., Conclusion: This study suggests that 'less than 50 years' old and 'over 3 h in operative duration' were risk factors of postlaparoscopic SP. To protect from SP after laparoscopy, some countermeasures should be necessary especially for these patients., (© 2020 Japan Society of Obstetrics and Gynecology.)

Aim: It is commonly thought that laparoscopic surgery leads to faster postoperative recovery for its low invasiveness. We evaluated postoperative quality of life (QOL) after laparoscopic myomectomy (LM) by using the Euro-QOL 5 dimension (EQ-5D) score and analyzed its relationship to surgical factors., Methods: Between 2014 and 2016, 541 patients underwent LM at our institution. We included 86 patients in the final analysis (16% response rate) who replied to the EQ-5D questionnaire, in order to investigate postoperative QOL. We evaluated patients' EQ-5D score before the operation and on the 3rd, 7th, 14th, 21st and 28th postoperative day (POD). We investigated the degree of correlation between the EQ-5D score and four surgical characteristics (operation time, intraoperative bleeding, number of resected myomas and weight of specimen). We examined correlation between EQ-5D scores and chief complaints such as hypermenorrhea, dysmenorrhea, other pain, myoma enlargement, palpable tumor and desire for childbearing. We also examined correlation between EQ-5D scores and other factors such as patient's age, infertility, history of abdominal surgery, marriage and body mass index., Results: Full recovery, defined as an EQ-5D score of 1.0, was reported 2.3% of patients by POD3, 18.6% by POD7, 58.1% by POD14, 73.3% by POD21 and 86.0% by POD28. Longer duration of operation correlated weakly with poor recovery on POD3. Intraoperative bleeding, number of resected myomas and weight of the specimen did not significantly influence EQ-5D score. There was no correlation between chief complaints or other factors mentioned above and EQ-5D score., Conclusions: More than a half of the patients undergoing LM included in our study reported full recovery of QOL after 2 weeks. The time to recover QOL was slightly influenced by the operation time. However, when LM was finished without any complications, postoperative QOL eventually seemed to improve regardless of the surgical characteristics such as operation time, intraoperative bleeding, number of resected myomas and weight of specimen., (© 2018 The Authors.

Objectives: To clarify the expression of multi-drug-resistant (MDR) markers, GST-pi, c-Jun, P-glycoprotein (Pgp), and MDR-associated protein (MRP) in epithelial ovarian cancer, and to determine whether their expression is predictive of chemotherapy response and patient prognosis., Methods: Specimens of 58 epithelial ovarian cancer cases obtained at initial surgery were studied immunohistochemically using antibodies., Results: Overall positive rates in the 58 specimens were 58.6% for GST-pi, 44.8% for c-Jun, 27.6% for Pgp, and 22.4% for MRP. The 5-year disease-free survival rate was 26.0% for patients with MRP-positive tumors and 75.2% for those with MRP-negative tumors. The prognosis for those with MRP-positive tumors was significantly poorer (p < 0.05). Patients with GST-pi-positive tumors had a significantly worse prognosis than those with GST-pi-negative tumors (51.9% vs 79.2%, p < 0.05). Multivariate analysis showed that residual tumors 2 cm or larger and MRP expression were independent prognostic factors for chemotherapy resistance. The relative risk of chemotherapy resistance in a patient with a residual tumor 2 cm or larger, positive MRP, and positive GST-pi was 10.6 times greater than the risk in a patient without these factors., Conclusion: MRP and GST-pi expression might be potential predictors of the response to standard chemotherapy in epithelial ovarian cancer. Their expression also might contribute to individualizing clinical trials of postoperative chemotherapy.
