Monitoring drainage flow rate facilitates prompt intervention with re-laparoscopy for postoperative bleeding after laparoscopic gynecologic surgery: A case-control study.

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.

Comparison of effect of preoperative dienogest and gonadotropin-releasing hormone agonist administration on laparoscopic cystectomy for ovarian endometriomas.

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.

Preimplantation Genetic Diagnosis and Natural Conception: A Comparison of Live Birth Rates in Patients with Recurrent Pregnancy Loss Associated with Translocation.

BACKGROUND: Established causes of recurrent pregnancy loss (RPL) include antiphospholipid syndrome, uterine anomalies, parental chromosomal abnormalities, particularly translocations, and abnormal embryonic karyotypes. The number of centers performing preimplantation genetic diagnosis (PGD) for patients with translocations has steadily increased worldwide. The live birth rate with PGD was reported to be 27-54%. The live birth rate with natural conception was reported to be 37-63% on the first trial and 65-83% cumulatively. To date, however, there has been no cohort study comparing age and the number of previous miscarriages in matched patients undergoing or not undergoing PGD. Thus, we compared the live birth rate of patients with RPL associated with a translocation undergoing PGD with that of patients who chose natural conception. METHODS AND FINDINGS: After genetic counseling, 52 patients who desired natural conception and 37 patients who chose PGD were matched for age and number of previous miscarriages and these comprised the subjects of our study. PGD was performed by means of fluorescence in situ hybridization analysis. The live birth rates on the first PGD trial and the first natural pregnancy after ascertainment of the carrier status were 37.8% and 53.8%, respectively (odds ratio 0.52, 95% confidence interval 0.22-1.23). Cumulative live birth rates were 67.6% and 65.4%, respectively, in the groups undergoing and not undergoing PGD. The time required to become pregnancy was similar in both groups. PGD was found to reduce the miscarriage rate significantly. The prevalence of twin pregnancies was significantly higher in the PGD group. The cost of PGD was $7,956 U.S. per patient. CONCLUSIONS: While PGD significantly prevented further miscarriages, there was no difference in the live birth rate. Couples should be fully informed of the similarity in the live birth rate, the similarity in time to become pregnancy, the advantages of PGD, such as the reduction in the miscarriage rate, as well as its disadvantages, such as the higher cost, and the advantages of a natural pregnancy, such as the avoidance of IVF failure. The findings presented here should be incorporated into the genetic counseling of patients with RPL and carrying a translocation.

[Review of 197 cases of urgent cesarean section performed in 2010 using NICE classification].

BACKGROUND: NICE (National Institute for Health and Clinical Excellence) of UK introduced a new classification of urgent cesarean section consisting of four categories. We classified 197 cases of urgent cesarean section performed at our institution between April 1st, 2010 and March 31, 2011, using the NICE classification. METHODS: Clinical records including obstetric record and anesthetic record were reviewed to identify possible cases as candidates of category 1 and 2, from 197 cases. Final classification was then decided at a case conference with four anesthesiologists and one obstetrician. RESULTS: Five cases were classified into category 1, and 51 cases were into category 2. There were 9 cases with umbilical pH < 7.2 among 51 cases of category 2. In these cases, quicker decision to delivery accompanies worse umbilical pH of the delivered neonate. CONCLUSIONS: The present review classifying urgent cesarean section using NICE classification revealed that most cases of urgent cesarean section were treated appropriately at our hospital. NICE guideline seems to be useful to improve anesthetic management of urgent cesarean section.
