The Influence of Surgical Complexity and Center Experience on Postoperative Morbidity After Minimally Invasive Surgery in Gynecologic Oncology: Lessons Learned from the ROBOGYN-1004 Trial.

BACKGROUND: This study was a secondary analysis of the ROBOGYN-1004 trial conducted between 2010 and 2015. The study aimed to identify factors that affect postoperative morbidity after either robot-assisted laparoscopy (RL) or conventional laparoscopy (CL) in gynecologic oncology. METHODS: The study used two-level logistic regression analyses to evaluate the prognostic and predictive value of patient, surgery, and center characteristics in predicting severe postoperative morbidity 6 months after surgery. RESULTS: This analysis included 368 patients. Severe morbidity occurred in 49 (28 %) of 176 patients who underwent RL versus 41 (21 %) of 192 patients who underwent CL (p = 0.15). In the multivariate analysis, after adjustment for the treatment group (RL vs CL), the risk of severe morbidity increased significantly for patients who had poorer performance status, with an odds ratio (OR) of 1.62 for the 1-point difference in the WHO performance score (95 % CI 1.06-2.47; p = 0.027) and according to the type of surgery (p < 0.001). A focus on complex surgical acts showed significant more morbidity in the RL group than in the CL group at the less experienced centers (OR, 3.31; 95 % CI 1.0-11; p = 0.05) compared with no impact at the experienced centers (OR, 0.87; 95 % CI 0.38-1.99; p = 0.75). CONCLUSION: The findings suggest that the center's experience may have an impact on the risk of morbidity for patients undergoing complex robot-assisted surgical procedures.

A systematic review and meta-analysis on mortality rate following total pelvic exenteration in cancer patients.

BACKGROUND: Total pelvic exenteration (TPE), an en bloc resection is an ultraradical operation for malignancies, and refers to the removal of organs inside the pelvis, including female reproductive organs, lower urological organs and involved parts of the digestive system. The aim of this meta-analysis is to estimate the intra-operative mortality, in-hospital mortality, 30- and 90-day mortality rate and overall mortality rate (MR) following TPE in colorectal, gynecological, urological, and miscellaneous cancers. METHODS: This is a systematic review and meta-analysis in which three international databases including Medline through PubMed, Scopus and Web of Science on November 2023 were searched. To screen and select relevant studies, retrieved articles were entered into Endnote software. The required information was extracted from the full text of the retrieved articles by the authors. Effect measures in this study was the intra-operative, in-hospital, and 90-day and overall MR following TPE. All analyzes are performed using Stata software version 16 (Stata Corp, College Station, TX). RESULTS: In this systematic review, 1751 primary studies retrieved, of which 98 articles (5343 cases) entered into this systematic review. The overall mortality rate was 30.57% in colorectal cancers, 25.5% in gynecological cancers and 12.42% in Miscellaneous. The highest rate of mortality is related to the overall mortality rate of colorectal cancers. The MR in open surgeries was higher than in minimally invasive surgeries, and also in primary advanced cancers, it was higher than in recurrent cancers. CONCLUSION: In conclusion, it can be said that performing TPE in a specialized surgical center with careful patient eligibility evaluation is a viable option for advanced malignancies of the pelvic organs.

Surgical training of gynecologic oncology fellows: Long-term trends and implications for future education.

OBJECTIVES: The surgical training of gynecologic oncology (GO) fellows is critical to providing excellent care to women with gynecologic cancers. We sought to evaluate changes in techniques and surgical volumes over an 18-year period among established GO fellowships across the US. METHODS: We emailed surveys to 30 GO programs that had trained fellows for at least 18 years. Surveys requested the number of surgical cases performed by a fellow for seventeen surgical procedures over each of five-time intervals. A One-Way Analysis of Variance was conducted for each procedure, averaged across institutions, to examine whether each procedure significantly changed over the 18-year span. RESULTS: 14 GO programs responded and were included in the analysis using SPSS. We observed a significant increase in the use of minimally invasive (MIS) procedures (robotic hysterectomy (p < .001), MIS pelvic (p = .001) and MIS paraaortic lymphadenectomy (p = .008). There was a concurrent significant decrease in corresponding "open" procedures. There was a significant decrease in all paraaortic lymphadenectomies. Complex procedures (such as bowel resection) remained stable. However, there was a wide variation in the number of cases reported with extremely small numbers for some critical procedures. CONCLUSIONS: The experience of GO fellows has shifted toward increased use of MIS. While these trends in care are appropriate, they do not diminish the need in many patients for complex open procedures. These findings should help spur the development of innovative training to maintain the ability to provide these core, specialty-defining procedures safely.

Implementation of a surgical site infection prevention bundle in gynecologic oncology patients: An enhanced recovery after surgery initiative.

OBJECTIVE: To evaluate the clinical outcomes pre- and post-implementation of an evidence-informed surgical site infection prevention bundle (SSIPB) in gynecologic oncology patients within an Enhanced Recovery After Surgery (ERAS) care pathway. METHODS: Patients undergoing laparotomy for a gynecologic oncology surgery between January-June 2017 (pre-SSIPB) and between January 2018-December 2020 (post-SSIPB) were compared using t-tests and chi-square. Patient characteristics, surgical factors, and ERAS process measures and outcomes were abstracted from the ERAS® Interactive Audit System (EIAS). The primary outcomes were incidence of surgical site infections (SSI) during post-operative hospital admission and at 30-days post-surgery. Secondary outcomes included total postoperative infections, length of stay, and any surgical complications. Multivariate models were used to adjust for potential confounding factors. RESULTS: Patient and surgical characteristics were similar in the pre- and post-implementation periods. Evaluation of implementation suggested that preoperative and intraoperative components of the intervention were most consistently used. Infectious complications within 30 days of surgery decreased from 42.1% to 24.4% after implementation of the SSIPB (p < 0.001), including reductions in wound infections (17.0% to 10.8%, p = 0.02), urinary tract infections (UTI) (12.7% to 4.5%, p < 0.001), and intra-abdominal abscesses (5.4% to 2.5%, p = 0.05). These reductions were associated with a decrease in median length of stay from 3 to 2 days (p = 0.001). In multivariate analysis, these SSI reductions remained statistically significant after adjustment for potential confounders. CONCLUSION: Implementation of SSIPB was associated with a reduction in SSIs and infectious complications, as well as a shorter length of stay in gynecologic oncology patients.

Efficacy, safety, and feasibility of Apixaban for postoperative venous thromboembolism prophylaxis following open gynecologic cancer surgery at a comprehensive cancer center.

OBJECTIVES: To evaluate safety, efficacy, and feasibility of apixaban for postoperative venous thromboembolism (VTE) prophylaxis following open gynecologic cancer surgery at a comprehensive cancer center. METHODS: This retrospective, cohort study included patients with gynecologic cancer who underwent open surgery between 3/2021 and 3/2023 and received 28-day postoperative VTE prophylaxis. Patients on therapeutic anticoagulation preoperatively were excluded. Predictors of 90- and 30-day VTE and 30-day bleeding events were determined using multivariable logistic regression, adjusting for known confounders. RESULTS: 452 patients were included in the cohort: 348 received apixaban and 104 received enoxaparin. Those who received enoxaparin were more likely to be American Society of Anesthesiologists class III/IV (compared to I/II) (p = 0.033), current or former smokers (p = 0.012) and have a higher BMI (p < 0.001), Charlson Comorbidity Index (p = 0.005), and age (p = 0.046). 30-day VTE rate was significantly lower in the apixaban group (0.6%) compared to the enoxaparin group (6.2%) (adjusted OR 0.13, 95% CI 0.03-0.56; p = 0.006). 90-day VTE rate was 2.7% and 6.2% in the apixaban and enoxaparin groups, respectively (adjusted OR 0.85, 95% CI 0.38-1.92; p = 0.704). Major bleeding complications (2.4% vs. 2.0%) and minor bleeding complications (0.9% vs. 3.0%) were similar in the apixaban and enoxaparin groups, respectively, on multivariate analyses. The median patient out of pocket cost was $10 (IQR 0.0-40.0) for apixaban and $20 (IQR 3.7-67.7) for enoxaparin (p = 0.001). CONCLUSIONS: Our findings along with previously published data suggest that apixaban should be considered the standard of care for VTE prophylaxis in patients undergoing open surgery for gynecologic malignancies.

Impact of pharmacogenomic profiles on post-surgical pain following laparotomy for gynecologic pathology.

OBJECTIVES: The aim of this prospective study was to compare perioperative opioid use in women by status of CYP2D6, a highly polymorphic pharmacogene relevant to opioid metabolism. METHODS: Patients undergoing laparotomy were prospectively recruited and provided a preoperative saliva swab for a pharmacogenomic (PGx) gene panel. Postoperative opioid usage and pain scores were evaluated via chart review and a phone survey. Pharmacogenes known to be relevant to opioid metabolism were genotyped, and opioid metabolizing activity predicted by CYP2D6 genotyping. Patient and procedural factors were compared using Fisher's exact and Kruskal-Wallis tests. RESULTS: The 96 enrolled patients were classified as ultra-rapid (N = 3, 3%), normal (58, 60%), intermediate (27, 28%), and poor (8, 8%) opioid metabolizers. There was no difference in surgical complexity across CYP2D6 categories (p = 0.61). Morphine Milligram Equivalents (MME) consumed during the first 24 h after peri-operative suite exit were significantly different between groups: ultrarapid metabolizers had the highest median MME (75, IQR 45-88) compared to the other three groups (normal metabolizers 23 [8-45], intermediate metabolizers 48 [20-63], poor metabolizers 31 [12-53], p = 0.03). Opioid requirements were clinically greater in ultrarapid metabolizers during the second 24 h and last 24 h but were statistically similar (p = 0.07). There was no difference in MME prescribed at discharge (p = 0.22) or patient satisfaction with pain control (p = 0.64) between groups. CONCLUSIONS: A positive association existed between increased CYP2D6 activity and in-hospital opioid requirements, especially in the first 24 h after surgery. This provides important information to further individualize opioid prescriptions for patients undergoing laparotomy for gynecologic pathology.

Prognostic Nutritional Index as a Predictive Biomarker of Post-Operative Infectious Morbidity in Gynecological Cancer Patients: A Prospective Cohort Study.

Malnutrition significantly impacts the post-operative process of gynecological cancer patients. A prominent variable for determining perioperative morbidity is the Prognostic Nutritional Index (PNI). To investigate PNI's predictive value on the risk of post-operative infections, we conducted a prospective cohort study involving women who underwent surgery for gynecological malignancies. Out of the 208 patients enrolled, 28 (13.5%) were malnourished and post-operative infections occurred in 43 patients. Notably, there was a significant difference in PNI between patients who developed infections and those who did not (p = 0.027), as well as between malnourished patients and those with normal nutritional status (p = 0.043). Univariate analysis showed that preoperative PNI predicts the risk of post-operative infections better than post-operative white blood cell count (AUC of 0.562 vs 0.375). However, the most accurate diagnostic results in the multivariate analysis were obtained from random forest and classification tree models (AUC of 0.987 and 0.977, respectively). Essentially, PNI and post-operative white blood cell count provided the best information gain according to rank probabilities. In conclusion, PNI appears to be a critical parameter that merits further investigation during the preoperative evaluation of gynecological malignancies.

Risk Factors Associated With Distress Among Postoperative Patients in an Academic Gynecologic Oncology Practice.

BACKGROUND: Distress among gynecologic oncology patients correlates with poor clinical outcomes and decreased quality of life. The purpose of this study was to determine risk factors for elevated NCCN Distress Thermometer (DT) results among postoperative gynecologic oncology patients. PATIENTS AND METHODS: We performed a retrospective chart review of all postoperative visits over a 5-year period. NCCN DT results were analyzed as both discretized values (DT ≤3 = low distress; DT 4-8 = moderate distress; DT ≥9 = high distress) and continuous variables. Patients with a DT score ≥4 were referred to social work. Univariate and multivariate regression analyses were performed to compare NCCN DT results with clinical and sociodemographic variables. Statistical significance was P<.05. RESULTS: In total, 1,795 NCCN DT results were included, with uterine (37.72%) being the most common disease site. Benign pathology was known prior to completion of the NCCN DT in 13.15% of patients. Most patients (71.75%) endorsed low levels of distress. Moderate/High levels of distress were reported by 28.25% of patients. Increasing levels of distress were significantly associated with younger age (P=.006), history of depression (P≤.001), status as a current smoker (P=.028), and history of asthma (P=.041). Knowledge of benign pathology was associated with low levels of distress (P=.002). Procedure type and disease site were not associated with distress. CONCLUSIONS: More than one-fourth of postoperative patients in a gynecologic oncology practice reported moderate or high distress. Distress was highest among those with malignancy regardless of disease site or surgical intervention. Benign pathology correlated with decreased distress. Identified associations with distress provide opportunities for prevention, early intervention, and tailored counseling.

Development and perception of surgery-specific goals of care discussions in the preoperative setting: A learning pilot.

BACKGROUND: Goals of care discussions are infrequently documented in the preoperative period. Furthermore, documentation does not consistently address what matters most to patients, although patient values (PV) are central to person-centered care. METHODS: A multidisciplinary working group was formed. An electronic note comprised of (1) topics of discussion, (2) PV, and (3) advance care planning (ACP), was created and embedded into existing note templates for Gynecologic Surgical Oncology. Surgeons and advanced practice providers (APPs) were educated to conduct and document these conversations in preoperative clinic for patients undergoing cancer surgery for a pilot period. Data were collected regarding usage of the template. Focus groups with surgeons, APPs, and patients were conducted. Qualitative analysis was performed on transcripts. RESULTS: During the pilot, 7 surgeon/APP teams utilized the template on a total of 55 notes. Average number of notes completed per surgeon was 7.8 (SD 8.5). Forty-six notes (84%) included topics of discussion, 15 (27%) included PV, 4 (7%) included ACP. Qualitative analysis of focus group transcripts revealed that clinicians and patients perceived the initiative to be useful and important, although implementation barriers were identified. CONCLUSION: Creating a surgery-specific GOC template is feasible. Iterative revisions are needed to increase utility in clinic workflows.

Fine-tuning the needle: analysis of acupuncturist response to alarming events during gynecological oncology surgery.

OBJECTIVE: Examining an intra-operative acupuncture/acupressure setting, with real-time "fine-tuning" in response to alarming events (AEvs) during gynecological oncology surgery. METHODS: Narratives of acupuncturists providing intraoperative acupuncture during gynecological oncology surgery were qualitatively analyzed. These described real time "fine-tuning" in response to AEvs during surgery, identified through hemodynamic changes (e.g., systolic/diastolic arterial pressure); bispectral index (BIS) elevation; and feedback from surgeons and anesthesiologists. Documentation of acupuncturist responses to AEvs was addressed as well. RESULTS: Of the 48 patients in the cohort, 33 had at least one intraoperative AEv (69%), of which 30 were undergoing laparoscopic surgery and 18 laparotomies. A total of 77 AEvs were documented throughout surgery (range 1-7; mean: 2.3 events per patient), identified through increased (63 events) or decreased (8) mean arterial pressure (MAP); increased BIS levels (2), or other hemodynamic parameters (4). Integrative oncology interventions implemented in response to AEs included acupressure alone (59); combining acupressure with acupuncture (10); or acupuncture alone (4). In 54 (70%) events, documentation was provided from beginning to conclusion of the AEv, with a mean duration of 9.7 min, with 32 events including a documented anesthesiologist intervention. CONCLUSION: The present study demonstrated the feasibility of intraoperative acupuncture with acupressure, with ongoing "fine-tuning" to AEvs identified through objective pain-related parameters (MAP, heart rate and BIS) and real-time input from surgeons and anesthesiologists. Documentation of the intraoperative IO practitioner's response to these AEvs is important, and should be addressed in future research of the innovative integrative model of care.

Medicolegal, infrastructural, and financial aspects in gynecologic cancer surgery and their implications in decision making processes: Quo Vadis?

Surgical decision making is complex and involves a combination of analytic, intuitive, and cognitive processes. Medicolegal, infrastructural, and financial factors may influence these processes depending on the context and setting, but to what extent can they influence surgical decision making in gynecologic oncology? This scoping review evaluates existing literature related to medicolegal, infrastructural, and financial aspects of gynecologic cancer surgery and their implications in surgical decision making. Our objective was to summarize the findings and limitations of published research, identify gaps in the literature, and make recommendations for future research to inform policy.

The art of bowel surgery in gynecologic cancer.

The field of gynecologic oncology has witnessed a profound transformation in the practice of bowel resection over the years. This evolution, driven by innovative techniques and expanded surgical skills, has redefined the role of the surgeon. This review article delves into the historical journey of bowel surgery, its contemporary importance in cytoreductive procedures for gynecologic cancers, and the general principles of digestive surgery. From pioneering surgeons such as Lane, Broca, and Billroth to the introduction of mechanical staplers, this narrative unfolds the remarkable advances in the field. It highlights the critical need for meticulous training, anatomic mastery, aseptic measures, vascular support, tension-free anastomoses, and precise surgical techniques. These principles underpin the success of bowel resection and anastomosis in the complex landscape of gynecologic oncology.

Trends and current aspects of reconstructive surgery for gynecological cancers.

Gynecologic cancers can lead to gynecologic tract destruction with extension into both the gastrointestinal and urinary tracts. Recurrent disease can also affect the surrounding bony pelvis and pelvic musculature. As opposed to advanced ovarian cancer, where cytoreduction is the goal, in these scenarios, an oncologic approach to achieve negative margins is critical for benefit. Surgeries aimed at achieving a R0 resection in gynecologic oncology can have a significant impact on pelvic anatomy, and require reconstruction. Overall, it appears that these types of radical surgery are less frequently performed; however, when required, multidisciplinary teams at high-volume centers can potentially improve short-term morbidity. There are few data to examine the long-term, quality-of-life outcomes after reconstruction following oncologic resection in advanced and recurrent gynecologic cancers. In this review we outline considerations and approaches for reconstruction after surgery for gynecologic cancers. We also discuss areas of innovation, including minimally invasive surgery and the use of 3D surgical anatomy models for improved surgical planning.In the era of 'less is more', pelvic exenteration in gynecologic oncology is still indicated when there are no other curative-intent alternatives in persistent or recurrent gynecological malignancies confined to the pelvis or with otherwise unmanageable symptoms from fistula or radiation necrosis. Pelvic exenteration is one of the most destructive procedures performed on an elective basis, which inevitably carries a significant psychologic, sexual, physical, and emotional burden for the patient and caregivers. Such complex ultraradical surgery, which requires removal of the vagina, vulva, urinary tract, and/or gastrointestinal tract, subsequently needs creative and complex reconstructive procedures. The additional removal of sidewall or perineal structures, like pelvic floor muscles/vulva, or portions of the musculoskeletal pelvis, and the inclusion of intra-operative radiation further complicates reconstruction. This review paper will focus on the reconstruction aspects following pelvic exenteration, including options for urinary tract restoration, reconstruction of the vulva and vagina, as well as how to fill large empty spaces in the pelvis. While the predominant gastrointestinal outcome after exenteration in gynecologic oncology is an end colostomy, we also present some novel new options for gastrointestinal tract reconstruction at the end.

Small bite fascial closure technique reduces incisional hernia rates in gynecologic oncology patients.

BACKGROUND: The potential for the technique of small bite fascial closure in mitigating incisional hernias in gynecologic oncology patients still needs to be investigated. OBJECTIVE: To evaluate the impact of closure of small fascial bites compared with prior standard closure on incisional hernia rates in gynecologic oncology patients. METHODS: This is a retrospective cohort study comparing patient outcomes before and after the intervention at a single institution at a comprehensive cancer center. Patients who underwent laparotomy with a vertical midline incision for a suspected or known gynecologic malignancy with a 1-year follow-up were included. The pre-intervention cohort (large bites) had 'mass' or modified running Smead-Jones closure. In contrast, the post-intervention cohort had fascial bites taken 5-8 mm laterally with no more than 5 mm travel (small bites) closure using a 2-0 polydioxanone suture.The primary outcome was the incisional hernias rate determined by imaging or clinical examination within the first year of follow-up. Patient factors and peri-operative variates of interest were investigated for their association with hernia formation through univariate and multivariate analyses. These included age, body mass index (BMI), smoking history, estimated blood loss, pre-operative albumin, American Society of Anesthesia (ASA) physical status classification, or treatment with chemotherapy post-operatively. RESULTS: Of the 255 patients included, the total hernia rate was 12.5% (32/255 patients). Patient characteristics were similar in both cohorts. Small bite closure led to a significant reduction in hernia rates from 17.2% (22/128 patients) to 7.9% (10/127 patients), p=0.025. According to logistic regression modeling, small bite closure (OR=0.40, 95% CI 0.17 to 0.94, p=0.036) was independently associated with lower odds of hernia formation. Other factors associated with increased hernia rates were chemotherapy (OR=3.22, 95% CI 1.22 to 8.51, p=0.019) and obesity (OR=23.4, 95% CI 3.09 to 177, p=0.002). In obese patients, small bite closures led to maximal hernia rate reduction compared with large bites. CONCLUSIONS: The small bite closure technique effectively reduces hernia rates in gynecologic oncology patients undergoing midline laparotomy.

Predictors and outcomes of same day discharge after minimally invasive hysterectomy in gynecologic oncology within the National Surgical Quality Improvement Program database.

OBJECTIVE: To assess trends over time of same day discharge after minimally invasive hysterectomy in oncology, identify perioperative factors influencing same day discharge, and evaluate 30 day postoperative morbidity. METHODS: A retrospective cohort of elective minimally invasive hysterectomies performed for gynecologic oncologic indications between January 2013 and December 2021 was identified using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Clinical and surgical characteristics, length of stay, and 30 day postoperative complications were captured. Clinical and surgical factors affecting same day discharge rate and impact of same day discharge on postoperative outcomes were evaluated using χ2 tests and logistic regression. RESULTS: Patients undergoing minimally invasive hysterectomy (n=32 823) had a same day discharge rate of 34.5% over the 9 year period, increasing from 15.5% in 2013 to 55.1% in 2021. The rate of patients discharged on postoperative day 1 decreased from 76.4% to 41.4% over this period. On multivariable analysis, same day discharge decreased with: age 70-79 years (odds ratio (OR) 0.80) and ≥80 years (OR 0.42); body mass index 40-49.9 kg/m2 (OR 0.89) and ≥50 kg/m2 (OR 0.67); patient comorbidities, including hypertension (OR 0.85), chronic steroid use (OR 0.74), bleeding disorder (OR 0.54), anemia (OR 0.89), and hypoalbuminemia (OR 0.76); and surgical time >90th percentile (OR 0.40) (all p<0.05). Lymphadenectomy did not impact the same day discharge rate (unadjusted OR 1.03, p=0.22). Same day discharge had no effect on 30 day postoperative composite morbidity (OR 0.91, p=0.20), and was associated with fewer readmissions (OR 0.75, p=0.005). Age 70-79 years (OR 1.07, p=0.435) and age ≥80 years (OR 1.11, p=0.504) did not increase postoperative morbidity. However, body mass index categories 40-49.9 kg/m2 (OR 1.28, 95% CI 1.08 to 1.51) and ≥50 kg/m2 (OR 1.60, 95% CI 1.27 to 2.01) were associated with greater 30 day composite morbidity. CONCLUSION: In this study, same day discharge following minimally invasive hysterectomy for oncologic indications was safe, and rates are rising among all age and body mass index categories. Quality improvement initiatives are needed at oncology centers to promote early discharge after minimally invasive gynecologic oncology surgery.

Assessment of socioeconomic and racial differences in patients undergoing concurrent gynecologic oncology and urogynecology surgeries: a National Inpatient Sample (NIS) database study.

OBJECTIVE: To assess social determinants of health impacting patients undergoing gynecologic oncology versus combined gynecologic oncology and urogynecology surgeries. METHODS: We identified patients who underwent gynecologic oncology surgeries from 2016 to 2019 in the National Inpatient Sample using the International Classification of Diseases-10 codes. Demographics, including race and insurance status, were compared for patients who underwent gynecologic oncology procedures only (Oncologic) and those who underwent concurrent incontinence or pelvic organ prolapse procedures (Urogynecologic-Oncologic). A logistic regression model assessed variables of interest after adjustment for other relevant variables. RESULTS: From 2016 to 2019 the National Inpatient Sample database contained 389 (1.14%) Urogynecologic-Oncologic cases and 33 796 (98.9%) Oncologic cases. Urogynecologic-Oncologic patients were less likely to be white (62.1% vs 68.8%, p=0.02) and were older (median 67 vs 62 years, p<0.001) than Oncologic patients. The Urogynecologic-Oncologic cohort was less likely to have private insurance as their primary insurance (31.9% vs 38.9%, p=0.01) and was more likely to have Medicare (52.2% vs 42.8%, p=0.01). After multivariable analysis, black (adjusted odds ratio (aOR) 1.41, 95% CI 1.05 to 1.89, p=0.02) and Hispanic patients (aOR 1.53, 95% CI 1.11 to 2.10, p=0.02) remained more likely to undergo Urogynecologic-Oncologic surgeries but the primary expected payer no longer differed significantly between the two groups (p=0.95). Age at admission, patient residence, and teaching location remained significantly different between the groups. CONCLUSIONS: In this analysis of a large inpatient database we identified notable racial and geographical differences between the cohorts of patients who underwent Urogynecologic-Oncologic and Oncologic procedures.

Sustainability of an enhanced recovery pathway after minimally invasive gynecologic oncology surgery.

OBJECTIVE: Same day discharge is safe after minimally invasive gynecology oncology surgery. Our quality improvement peri-operative program based on enhanced recovery after surgery principles led to an increase in same day discharge from 30% to 75% over a 12 month period. Twelve months after program implementation, we assessed the sustainability of same day discharge rates, determined post-operative complication rates, and evaluated factors affecting same day discharge rates. METHODS: A retrospective chart review was conducted of 100 consecutive patients who underwent minimally invasive surgery at an academic cancer center from January to 2021 to December 2021. This cohort was compared with the active intervention cohort (n=102) from the implementation period (January 2020 to December 2020). Same day discharge rates and complications were compared. Multivariable analysis was performed to assess which factors remained associated with same day discharge post-intervention. RESULTS: Same day discharge post-intervention was 72% compared with 75% during active intervention (p=0.69). Both cohorts were similar in age (p=0.24) and body mass index (p=0.27), but the post-intervention cohort had longer operative times (p=0.001). There were no significant differences in 30-day complications, readmission, reoperation, or emergency room visits (p>0.05). There was a decrease in 30-day post-operative clinic visits from 18% to 5% in the post-intervention cohort (p=0.007), and unnecessary bowel prep use decreased from 35% to 14% (p<0.001). On multivariable analysis, start time (second case of the day) (OR 0.06; 95% CI 0.01 to 0.35), and ward narcotic use (OR 0.12; 95% CI 0.03 to 0.42) remained associated with overnight admission. CONCLUSION: Same day discharge rate was sustained at 72%, 12 months after the implementation of a quality improvement program to optimize same day discharge rate after minimally invasive surgery, while maintaining low post-operative complications and reducing unplanned clinic visits. To maximize same day discharge, minimally invasive gynecologic oncology surgery should be prioritized as the first case of the day, and post-operative narcotic use should be limited.

Surgical options for lymphedema after gynecological cancer treatment: current trends and advances.

Lower leg lymphedema is an important complication after gynecological treatment that can severely affect the quality of life of long-term survivors of these malignancies. As a chronic and progressive disease, affected patients will require life-long therapy centered on compression. Although conventional compressive treatments can be effective, they are extremely burdensome and time-consuming for most patients and adherence is challenging. With advances in the field of reconstructive microsurgery, new procedures have been developed in the past decades to help these patients in their continuous care and have been offered at many oncological centers around the world as a first line of treatment. We performed a PubMed search using the Mesh terms 'Lymphedema/surgery' and 'Lower extremity' yielding a total of 508 articles. Of these, 35 articles were included for analysis. Articles that failed to provide a comprehensive analysis of outcomes following surgical treatment, studies examining treatment for upper limb lymphedema, primary lymphedema, or lower extremity lymphedema resulting from non-gynecologic etiologies, and studies that failed to have a minimum of 6 months follow-up were excluded. A comprehensive review of these 35 articles including over 1200 patients demonstrated large variability on the outcomes reported; however, an overall benefit from these procedures was found. Surgical options including lymphovenous anastomosis, vascularized lymph node transfers, and excisional procedures can be performed in patients with lower leg lymphedema, depending on staging and findings in indocyanine green lymphography. Surgical treatment of lymphedema is an effective option that can improve symptoms and quality of life of patients suffering from lymphedema following gynecologic cancers.

Effect of Enoxaparin and Daikenchuto Coadministration on Hepatic Disorder Markers in Gynecological Cancer Patients after Abdominal Surgery.

Enoxaparin and daikenchuto are commonly administered to prevent venous thromboembolism and intestinal obstruction after gynecological malignancy surgery. However, the effects of their combined use on hepatic function are not well studied. This study aimed to clarify the effects of the coadministration of enoxaparin and daikenchuto on hepatic function. First, Japanese Adverse Drug Event Report (JADER) data were analyzed to identify signals of hepatic disorders. Second, a retrospective observational study of patients who underwent surgery for gynecological malignancies was conducted. This study defined hepatic disorders as an increase in aspartate aminotransferase (AST) or alanine aminotransaminase (ALT) levels above the reference values, using 1-h postoperative values as the baseline. The analysis of JADER data revealed an increased risk for hepatic disorders with the coadministration of enoxaparin and daikenchuto. An observational study also showed higher odds ratios (95% confidence intervals) for the occurrence of hepatic disorders in the coadministration group (4.27; 2.11-8.64) and enoxaparin alone group (2.48; 1.31-4.69) than in the daikenchuto alone group. The median increase in the ALT level was also higher in the coadministration group (34; 15-59) than in the enoxaparin alone (19; 6-38) and daikenchuto alone groups (8; 3-33). In conclusion, our study suggests that compared with the use of enoxaparin or daikenchuto alone, enoxaparin and daikenchuto coadministration increases the risk of hepatic disorders, with more significant increases in AST and ALT levels. Healthcare workers need to be aware of these potential side effects when combining these drugs after surgery for gynecological malignancies.
