ABSTRACT
STUDY OBJECTIVE: We sought to identify the variables independently associated with intra/postoperative blood transfusion at the time of myomectomy. We further hoped to develop an accurate prediction model using preoperative variables to categorize an individual's risk of blood transfusion during myomectomy. DESIGN: Case-control study. SETTING: Not applicable to this study, which used the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. PATIENTS: Women who underwent an open/abdominal or laparoscopic (robotic or conventional) myomectomy between 2014 and 2017 at participating ACS-NSQIP sites. INTERVENTION: The primary dependent variable was occurrence of intra/postoperative bleeding requiring blood transfusion. Patient demographics, clinical characteristics, preoperative comorbidities, intraoperative variables, and additional 30-day postoperative outcomes were compared at the bivariable level. For the prediction-model development, only variables that can be reasonably known before surgery were included. Variables associated with intra/postoperative bleeding were entered into 2 separate multivariable logistic regression models. Validation of our prediction model was performed internally using 250 bootstrapped iterations of 50% subsamples drawn from the overall population of myomectomy cases from the ACS-NSQIP database. MEASUREMENTS AND MAIN RESULTS: We identified 6387 myomectomies performed during the defined study period. The most common race in our population was black/African American (45.7%), and most of the patients (57.5%) received an open/abdominal route of myomectomy. A total of 623 patients who underwent myomectomy (9.8%) experienced intraoperative/postoperative bleeding with a need for blood transfusion. At the bivariable level, we identified several variables independently associated with the need for blood transfusion at the time of myomectomy. In using only those variables that can be reasonably known before surgery to develop our prediction model, additional multivariable logistic regression elucidated black race, need for preoperative blood transfusion, planned abdominal/open route of surgery, and preoperative hematocrit value as independently associated with blood transfusion. CONCLUSION: We identified a number of perioperative variables associated with intraoperative or postoperative bleeding requiring blood transfusion at the time of myomectomy. We subsequently created a model that accurately predicts individual bleeding risk from myomectomy, using variables that are reasonably apparent preoperatively. Making this prediction model clinically available to gynecologic surgeons will serve to improve the care of women undergoing myomectomy.

PURPOSE OF REVIEW: Bleeding at the time of benign gynecologic surgery, as well as from benign gynecologic conditions, is a major source of morbidity for many women. Few nonhormonal medical options exist for the treatment of heavy menstrual bleeding, and to reduce surgical bleeding during major gynecologic surgery. Interest in Tranexamic acid (TXA) as a means to reduce surgical blood loss has been growing across many surgical specialties. This review focuses on applications for TXA as a means to reduce heavy menstrual bleeding (HMB) as well as to reduce surgical bleeding during benign gynecologic surgery. RECENT FINDINGS: Tranexamic acid is an effective treatment to reduce the volume of bleeding during menstruation. Tranexamic acid was found to be superior to both placebo and oral progestins, and as good as combined oral contraceptives at reducing menstrual blood volume. Tranexamic acid has also been show to reduce the volume of bleeding during abdominal myomectomy as well as hysterectomy. There is a major need for prospective studies evaluating the utility of TXA for reducing blood loss during benign gynecologic surgery. SUMMARY: Tranexamic acid has been found to be an excellent affordable nonhormonal treatment option for women with HMB and should be considered during major gynecologic surgery.

OBJECTIVES: There is conflicting research on the effect of therapeutic suggestion in the perioperative period. This study systematically compared subjective and objective measures of postoperative pain, nausea and vomiting, urinary and bowel function, and global perception of symptomatic improvement between participants receiving perioperative therapeutic suggestion versus routine perioperative care during minimally invasive pelvic reconstructive surgery. METHODS: This was a single-blinded, randomized controlled trial of participants undergoing vaginal hysterectomy with minimally invasive sacrocolpopexy and concomitant prolapse repairs. The intervention group received perioperative therapeutic suggestion, whereas the control group did not. Primary outcomes included postoperative pain scores and analgesic use. Secondary outcomes included a postoperative nausea and vomiting scale, the Pelvic Floor Distress Inventory Questionnaire-Short Form 20, the Patient Global Impression of Improvement scale, and time to return of bowel and bladder function. RESULTS: Sixteen participants were randomized to each group. Final analysis included 15 intervention and 14 control participants. Overall measures of postoperative pain and analgesic use were low across all participants without a significant difference between intervention and control groups (opioid: 52.5; interquartile range [IQR], 25.5-58.9 vs 66 IQR, 7.3-125.8; morphine milligram equivalents; P = 0.64; acetaminophen: 2225 mg; IQR, 500-2600 mg vs 2800 mg; IQR, 650-4775 mg; P = 0.38). There were no statistically significant differences in secondary outcomes of urinary symptoms, bowel function, and subjective improvement of prolapse symptoms. CONCLUSIONS: No differences in postoperative pain, analgesic use, return of bowel and bladder function, or pelvic organ prolapse symptoms were noted in participants receiving perioperative therapeutic suggestion versus routine perioperative care.

OBJECTIVE: Clarify the normal patterns of voiding after minimally invasive hysterectomy. We also aim to identify perioperative factors associated with delayed time to void immediately following hysterectomy. DESIGN: Retrospective cohort study SELECTION: Women undergoing laparoscopic hysterectomy between September 2012 to October 2018 at a single academic university hospital. RESULTS: 450 minimally invasive hysterectomies were included in the final analysis, 274 (60.9%) robotically-assisted, and 176 (39.1%) conventional laparoscopy. The overall median postoperative time-to-void following a retrograde bladder filling of 150 mL normal saline was 179 min. Based on the 50th percentile of the distribution of the time-to-void, two groups were created. Demographic characteristics between the groups were similar, except those who were above the 50th percentile were more likely to be older, have a reported history of previous myomectomy, and had a longer postoperative PACU stay compared to those below or equal to the 50th percentile. The mean time-to-void following conventional laparoscopic hysterectomy was less than that of robotic surgery (187.3 vs 200.5 min) however the difference was not statistically significant (p=.22). The use of hydromorphone intraoperatively and the combination of oxycodone-acetaminophen postoperatively were more likely to be associated with the group of patients above the 50th percentile but there was no significant difference in perioperative utilization of median morphine milliequivalents (MME) between the two groups. CONCLUSIONS: Following laparoscopic hysterectomy (either conventional or with robotic-assistance) with a retrograde bladder fill of 150 mL normal saline most patients will void within 4 h after surgery. This is consistent with historic data on normal voiding patterns facilitating safe same day discharge without prolonged time in the PACU.
