A cystectomic technique with low risk of rupture for women with benign ovarian cyst.

The majority of patients with benign ovarian cysts undergo laparoscopic surgery using both cystectomy and stripping techniques. However, these techniques have difficulty correctly identifying cleavage planes and are prone to cyst rupture. We present a surgical cystectomy technique that correctly identifies the cleavage plane with a low risk of ovarian cyst rupture, even in patients with multicystic ovarian cysts. Cystectomy was performed using Maryland forceps with gentle open and close dissecting motions only. Both the surgeon and assistant handled the ovarian cortex and cyst wall, and soft traction between the cortex and cyst wall as far as the nearby dissection plane without grasping the cyst wall was essential. In patients with multicystic ovarian cysts, making a plane at the notch between cysts decreases the risk of cyst rupture. This technique allows the correct identification of the cleavage plane for dissection and avoids the risk of cyst rupture.Impact StatementWhat is already known on this subject? The majority of patients with benign ovarian cysts undergo laparoscopic surgery using both cystectomy and stripping techniques. These techniques have difficulty correctly identifying cleavage planes and are prone to cyst rupture.What do the results of this study add? This technique allows the correct identification of the cleavage plane for dissection and avoids the risk of cyst rupture.What are the implications of these findings for clinical practice and/or further research? Our technique might be useful for the preservation of the ovarian reserve because patients in this study had a low proportion of ovarian follicles in the surgical specimen.

Nedaplatin use in patients with hypersensitivity reaction episodes to carboplatin.

OBJECTIVE: To evaluate the benefits of nedaplatin treatment in patients with a history of hypersensitivity reactions to carboplatin. MATERIALS AND METHODS: We retrospectively reviewed the medical records of patients with ovarian, fallopian, and peritoneal cancers and with a history of hypersensitivity to carboplatin between January 2010 and December 2016 at the Department of Gynecology in the Saitama Medical Center associated with Jichi Medical University. We studied the response rate to treatment with a nedaplatin-based regimen compared to that of a carboplatin regimen. Fisher's exact test was used to determine statistical significance. RESULTS: Thirty-one patients with a past hypersensitivity to carboplatin were treated with nedaplatin-based regimen, while ten patients were treated with other drugs. The response rates in the nedaplatin- and non-nedaplatin-treated patient groups were 71.4% and 30.0%, respectively (P = 0.021). Among all the patients, only one experienced hypersensitivity reaction to nedaplatin. CONCLUSION: The nedaplatin regimen following hypersensitivity to carboplatin was safe, feasible, and effective in achieving complete or partial response.

Huge fetal ovarian cyst.

Most fetal ovarian cysts increase in size during the late stages of pregnancy. Early treatment of a huge neonatal cyst may reduce the risk of gastrointestinal obstruction.

Placental mesenchymal dysplasia with a good outcome: A case report.

Placental mesenchymal dysplasia (PMD), characterized by an enlarged and thickened placenta with multiple hypoechoic cystic spaces, frequently leads to a poor infantile/fetal outcome. Here, we describe a case of PMD involving an infant delivered at term with a good outcome. The fetus was male, and the proportion of the PMD lesion to the entire placenta remained constant: the PMD lesion did not enlarge. Given what is known about the pathogenesis of PMD with its association with vascular endothelial growth factor-D (VEGF-D) encoded by an X-linked gene and androgenetic/biparental mosaicism, which is consistent with female dominancy and a poor outcome, we suggest that a male sex of the fetus and non-progressing PMD may have been associated with this good outcome.

Open fan sign: An ultrasound finding suggesting postpartum intrauterine forgotten gauze.

Gauze counting is regarded as the most essential way to prevent forgotten gauze inside the body during any surgery. However, incident may still occur due to artificial mistake. An open fan sign on ultrasonography may indicate a gauze left in the intrauterine cavity.

Rupture of hidden abnormal myometrial vessels during cesarean delivery of a patient with subserosal leiomyoma: A possible pathogenesis of sudden-onset disseminated intravascular coagulation.

We report a case of sudden-onset disseminated intravascular coagulation during cesarean delivery for a patient with a subserosal leiomyoma. Rupture of hidden anastomotic vessels resulted in a significant decrease in fibrinogen levels and uncontrolled bleeding. Uterine venous flow disturbance caused by subserosal leiomyoma compression can possibly cause such a situation.

Preoperative administration of eculizumab to prevent surgery-triggered hemolysis during cesarean section with paroxysmal nocturnal hemoglobinuria.

Eculizumab in pregnancy has been reported to be effective in improving outcomes in patients with paroxysmal nocturnal hemoglobinuria. However, a cesarean section may result in surgery-triggered hemolysis. An additional dose of eculizumab just prior to delivery is an appropriate choice to prevent postoperative hemolysis.

Vulvar intraepithelial neoplasia treated with a combination of surgical excision and laser ablation during pregnancy.

Most vulvar intraepithelial neoplasias are associated with human papillomavirus. However, detailed surgical plans during pregnancy are rarely discussed. We suggest that the treatment policy should focus on performing surgical excision on multifocal lesions, combined surgical excision/laser ablation on single lesions, and preserving unaffected perineal skin, if possible.

Can biparietal diameter-to-femur length ratio be a useful sonographic marker for screening thanatophoric dysplasia since the first trimester? A literature review of case reports and a retrospective study based on 10,293 routine fetal biometry measurements.

OBJECTIVE: The aim of the study was to determine whether the biparietal diameter/femur length (BPD/FL) ratio can be used to detect thanatophoric dysplasia in the first trimester of pregnancy. MATERIALS AND METHODS: Twenty-four reported cases of thanatophoric dysplasia diagnosed based on ultrasonographic results with molecular or radiographic diagnosis were included. All sonographic measurement records were extracted and reviewed, and the BPD/FL ratio was calculated for each gestational week. In addition, 10,293 routine fetal biometry measurements from 1395 cases of patients without skeletal dysplasia were compared. RESULTS: The BPD/FL ratio in the control group decreased to less than 3 prior to gestational week 13, and to less than 2 prior to week 18. Of the 27 BPD/FL ratios obtained from 24 cases of thanatophoric dysplasia, none was in the control range. CONCLUSION: The BPD/FL ratio may be used to detect lethal skeletal dysplasias such as thanatophoric dysplasia since the first trimester.

Efficacy and safety of cell-free and concentrated ascites reinfusion therapy (CART) in gynecologic cancer patients with a large volume of ascites.

AIM: The aim of this study was to evaluate the efficacy and safety of cell-free concentrated ascites reinfusion therapy (CART) on a large amount of ascites. MATERIAL AND METHODS: Fifty-eight CART procedures were performed in nine patients with ovarian, endometrial, or cervical cancer from February 2013 to September 2014. The medical records were retrospectively reviewed for the amount of collected ascites, vital signs, and laboratory results before and after CART. RESULTS: No obvious change in the plasma protein and plasma albumin concentration was found after CART for < 5 L of ascites; however, obvious increases in both were observed in CART for ≥ 5 L of ascites (P < 0.001). The optimum cut-off value for obtaining a positive variant of plasma protein and plasma albumin after CART was 7.9 L. CART for ≥ 5 L of ascites did not increase the risk of transient water retention in the body (odds ratio = 2.2; 95% confidence interval: 0.35-13.83; P = 0.38); however, CART for ≥ 7.9 L of ascites increased the risk of water retention (odds ratio = 8.4; 95% confidence interval: 1.91-44.09; P = 0.004). The optimal cut-off value of ascites for predicting water retention due to CART was 9.2 L. CONCLUSION: Massive ascites collection in CART < 9.2 L appears to be a safe and effective treatment for improving general condition, plasma protein, and electrolytes in gynecologic cancer patients.
