Defining and mitigating the challenges of an older and obese population in minimally invasive gynecologic cancer surgery

Frailty and the Survival of Patients With Endometrial Cancer: A Meta-Analysis

The aim of this study is to investigate the association between frailty and overall survival (OS) and progression-free survival (PFS) in women with endometrial cancer (EC). Frailty is increasingly recognized as a significant predictor of outcomes in cancer patients, yet its impact on survival among EC patients remains unclear. This study is a systematic review and meta-analysis. PubMed, Embase, and Web of Science from database inception to September 28, 2024 were searched for cohort studies evaluating frailty in relation to survival in EC patients. Inclusion criteria focused on studies reporting hazard ratios (HRs) for OS or PFS, comparing frail versus nonfrail patients. A random-effects model was applied. Eight cohort studies involving 486,138 women reported the outcome of OS, and 4 of them involving 378 women also reported the outcome of PFS. Frailty was associated with poor OS (HR: 1.78, 95% confidence interval [CI]: 1.56-2.03, p < 0.001) without significant heterogeneity (I2 = 0%). Sensitivity analyses confirmed the stability of this association. Subgroup analyses according to the mean age of the patients, tools for evaluating frailty, follow-up duration, and study quality score showed consistent results (p for subgroup difference: 0.35-0.98). Four studies indicated a significant association between frailty and worse PFS (HR: 1.91, 95% CI: 1.24-2.95, p = 0.003), also with no heterogeneity (I2 = 0%). The results of the study conclude that frailty is associated with poor survival in EC. Although these findings should be validated in large prospective cohort studies, this meta-analysis highlights the possible role of frailty assessment in risk stratification and prognostic prediction of patients with EC. No patient or public contribution.

Definition and diagnostic criteria of clinical obesity

Current BMI-based measures of obesity can both underestimate and overestimate adiposity and provide inadequate information about health at the individual level, which undermines medically-sound approaches to health care and policy. This Commission sought to define clinical obesity as a condition of illness that, akin to the notion of chronic disease in other medical specialties, directly results from the effect of excess adiposity on the function of organs and tissues. The specific aim of the Commission was to establish objective criteria for disease diagnosis, aiding clinical decision making and prioritisation of therapeutic interventions and public health strategies. To this end, a group of 58 experts—representing multiple medical specialties and countries—discussed available evidence and participated in a consensus development process. Among these commissioners were people with lived experience of obesity to ensure consideration of patients’ perspectives. The Commission defines obesity as a condition characterised by excess adiposity, with or without abnormal distribution or function of adipose tissue, and with causes that are multifactorial and still incompletely understood. We define clinical obesity as a chronic, systemic illness characterised by alterations in the function of tissues, organs, the entire individual, or a combination thereof, due to excess adiposity. Clinical obesity can lead to severe end-organ damage, causing life-altering and potentially life-threatening complications (eg, heart attack, stroke, and renal failure). We define preclinical obesity as a state of excess adiposity with preserved function of other tissues and organs and a varying, but generally increased, risk of developing clinical obesity and several other non-communicable diseases (eg, type 2 diabetes, cardiovascular disease, certain types of cancer, and mental disorders). Although the risk of mortality and obesity-associated diseases can rise as a continuum across increasing levels of fat mass, we differentiate between preclinical and clinical obesity (ie, health vs illness) for clinical and policy-related purposes. We recommend that BMI should be used only as a surrogate measure of health risk at a population level, for epidemiological studies, or for screening purposes, rather than as an individual measure of health. Excess adiposity should be confirmed by either direct measurement of body fat, where available, or at least one anthropometric criterion (eg, waist circumference, waist-to-hip ratio, or waist-to-height ratio) in addition to BMI, using validated methods and cutoff points appropriate to age, gender, and ethnicity. In people with very high BMI (ie, >40 kg/m2), however, excess adiposity can pragmatically be assumed, and no further confirmation is required. We also recommend that people with confirmed obesity status (ie, excess adiposity with or without abnormal organ or tissue function) should be assessed for clinical obesity. The diagnosis of clinical obesity requires one or both of the following main criteria: evidence of reduced organ or tissue function due to obesity (ie, signs, symptoms, or diagnostic tests showing abnormalities in the function of one or more tissue or organ system); or substantial, age-adjusted limitations of daily activities reflecting the specific effect of obesity on mobility, other basic activities of daily living (eg, bathing, dressing, toileting, continence, and eating), or both. People with clinical obesity should receive timely, evidence-based treatment, with the aim to induce improvement (or remission, when possible) of clinical manifestations of obesity and prevent progression to end-organ damage. People with preclinical obesity should undergo evidence-based health counselling, monitoring of their health status over time, and, when applicable, appropriate intervention to reduce risk of developing clinical obesity and other obesity-related diseases, as appropriate for the level of individual health risk. Policy makers and health authorities should ensure adequate and equitable access to available evidence-based treatments for individuals with clinical obesity, as appropriate for people with a chronic and potentially life-threatening illness. Public health strategies to reduce the incidence and prevalence of obesity at population levels must be based on current scientific evidence, rather than unproven assumptions that blame individual responsibility for the development of obesity. Weight-based bias and stigma are major obstacles in efforts to effectively prevent and treat obesity; health-care professionals and policy makers should receive proper training to address this important issue of obesity. All recommendations presented in this Commission have been agreed with the highest level of consensus among the commissioners (grade of agreement 90–100%) and have been endorsed by 76 organisations worldwide, including scientific societies and patient advocacy groups.

Robotic salvage radical hysterectomy for locally recurrent cervical cancer: A comparison with open surgery in a single-surgeon series

AIM

To compare the surgical and oncologic outcomes between patients with locally recurrent cervical cancer undergoing robotic-assisted salvage radical hysterectomy (RH) and those undergoing conventional open salvage RH, performed by a single surgeon.

METHODS

This retrospective comparative observational study utilized data obtained from consecutive patients with locally recurrent cervical cancer, developed after definitive radiotherapy. These patients either underwent robot-assisted RH (robotic group) or conventional open RH (open group). Clinicopathological characteristics, surgical outcomes, and oncological outcomes were compared between the two groups.

RESULTS

The operative time was slightly longer in the robotic group; however, this difference was not statistically significant. Estimated blood loss was significantly lower in the robotic group (median; 0 mL [robotic group] vs. 700 mL [open group]: p < 0.01). The incidence of intraoperative and early and late complications did not statistically differ between the two groups. The mean follow-up was 29.0 and 17.1 months in the open and robotic groups, respectively. Disease recurrence rates were similar between the two groups (40% [robotic group] vs. 44.4% [open group]). Kaplan-Meier survival analysis for progression-free survival and overall survival did not show statistically significant differences between the two groups.

CONCLUSION

Robot-assisted salvage RH in women with locally recurrent cervical cancer showed perioperative and oncological outcomes comparable to those of the open procedure. Although our results suggest that the robot-assisted approach is as good as or better than the open approach, further investigation is required to establish a more robust conclusion.

Low-Pressure Laparoscopy Using the AirSeal System versus Standard Insufflation in Early-Stage Endometrial Cancer: A Multicenter, Retrospective Study (ARIEL Study)

The aim of our study was to evaluate the benefits of a low-pressure insufflation system (AirSeal) vs. a standard insufflation system in terms of anesthesiologists’ parameters and postoperative pain in patients undergoing laparoscopic surgery for early-stage endometrial cancer. This retrospective study involved five tertiary centers and included 152 patients with apparent early-stage disease who underwent laparoscopic surgical staging with either the low-pressure AirSeal system (8−10 mmHg, n = 84) or standard laparoscopic insufflation (10−12 mmHg, n = 68). All the intraoperative anesthesia variables evaluated (systolic blood pressure, end-tidal CO2, peak airway pressure) were significantly lower in the AirSeal group. We recorded a statistically significant difference between the two groups in the median NRS scores for global pain recorded at 4, 8, and 24 h, and for overall shoulder pain after surgery. Significantly more women in the AirSeal group were also discharged on day one compared to the standard group. All such results were confirmed when analyzing the subgroup of women with a BMI >30 kg/m2. In conclusion, according to our preliminary study, low-pressure laparoscopy represents a valid alternative to standard laparoscopy and could facilitate the development of outpatient surgery.

A Comparative Study of Braided versus Barbed Suture for Cystotomy Repair

Background

In this study, we aim to compare outcomes after cystotomy repair between standard sutures (910 polyglactin, poliglecaprone) versus barbed (V-Loc^TM 90) suture. As a secondary outcome, we analyzed factors for suture preference between the two groups.

Methods

A retrospective chart review was undertaken for surgeries complicated by cystotomy, identified by ICD-9/10 codes from 2016 to 2019 at West Virginia University (WVU) Hospital. Comparisons were made between cystotomy repair using barbed suture versus standard braided suture. Injuries were categorized by procedure, surgical route, type of suture used in repair, and subsequent complications related to repair. Primary endpoints were examined by Pearson's Chi-square test and interval data by t-test. A p < 0.05 was significant.

Results

Sixty-eight patients were identified with iatrogenic cystotomy at WVU. Barbed suture was used for cystotomy repair in 11/68 (16.2%) patients. No significant difference was seen in postoperative outcomes between patients repaired with barbed suture versus standard braided suture. Barbed suture was significantly more likely to be used for cystotomy repair in minimally invasive surgery (p = 0.001). It was most often utilized in a robotic approach 7/11 (63.6%) followed by laparoscopic 3/11 (27.3%). Body mass index (BMI) was significantly higher in patients receiving a barbed suture repair (p = 0.005).

Conclusion

Barbed suture may be comparable to standard braided suture for cystotomy repair. Barbed suture may offer a practical alternative to facilitate cystotomy repair in minimally invasive surgery, especially in patients with a high BMI.

Safety and efficacy of synchronous panniculectomy and endometrial cancer surgery in obese patients: a systematic review of the literature and meta-analysis of postoperative complications

Panniculectomy combined with gynaecological surgery constitutes an alternative approach for endometrial cancer (EC) in obese patients. The present study aimed to assess the current knowledge concerning the safety and efficacy of combining panniculectomy in surgical management of EC. Four electronic databases were systematically searched for articles published up to May 2019. A total of five studies, of which two were non-comparative and three comparative, were included. Meta-analysis of complications among panniculectomy and conventional laparotomy group revealed no difference in either intra- or post-operative complication rates. Moreover, no difference was reported in surgical site complications (p=0.59), while wound breakdown rates were significantly elevated in the laparotomy group (p=0.02). Panniculectomy combined surgery for the management of EC appears to be a safe procedure and results in comparable outcomes compared with conventional laparotomy with regard to complications and improved wound breakdown rates.

National trends and outcomes of morbidly obese women who underwent inpatient hysterectomy for benign gynecological disease in the USA

INTRODUCTION

The US population has witnessed an epidemic expansion of obesity in the past several decades; nearly 50% of the population is projected to be obese by 2030 and 25% morbidly obese. This study examined trends, characteristics and outcomes of morbidly obese women who underwent benign hysterectomy.

MATERIAL AND METHODS

This is a population-based retrospective observational study querying the National Inpatient Sample from January 2012 to September 2015. The study population included 509 395 women who underwent hysterectomy for benign gynecological disease: 430 865 (84.6%) non-obese women, 50 435 (9.9%) women with class I-II obesity and 28 095 (5.5%) women with class III obesity. Main outcome measures were (i) cohort-level trends of obesity and perioperative complications assessed by piecewise linear regression with log transformation and (ii) patient-level perioperative complication risk by body habitus assessed with a generalized estimating equation after using a multiple-group generalized boosted model.

RESULTS

The rate of class III obesity increased by 40.4%, higher than the rate of class I-II obesity (22.2%) (both, P < .001). In parallel, cohort-level rates of perioperative complication and prolonged hospitalization for ≥7 days increased by 19.4% and 54%, respectively (P < .001). In a weighted model, class I-II obesity (16.4% vs 14.6%, odds ratio 1.15, 95% confidence interval 1.08-1.21) and class III obesity (19.2% vs 14.6%, odds ratio 1.39, 95% confidence interval 1.28-1.51) had a significantly increased risk of perioperative complications compared with non-obesity. Larger body habitus was associated with higher total charge (median, $35 180, $36 094 and $39 382; all values cited in US dollars) and prolonged admission rate for ≥7 days (2.9%, 3.1% and 3.9%) (both, P < .001).

CONCLUSIONS

The rate of obesity, particularly morbid obesity, has significantly increased among women undergoing benign hysterectomy in the USA. Morbidly obese women had adverse perioperative outcomes, and the increasing number of morbidly obese women resulted in both an increased perioperative morbidity and total charges as a cohort. National and society-based approaches are necessary to reduce the obesity rate and hysterectomy morbidity.

Perioperative management of positioning in gynecological cancersurgery: a national NOGGO-AGO intergroup survey

INTRODUCTION

The daily clinical routine in the operating room includes patient positioning. The number of perioperative positioning-related complications is growing, along with the legal proceedings concerning this topic, and only a few guidelines exist to provide specific recommendations. The aim of this survey was to assess perioperative positioning and associated adverse events during gynecological cancer surgery in Germany.

METHODS

A total of 633 gynecological departments of primary, secondary, and maximum healthcare hospitals in Germany were invited to participate in this multiple-choice online questionnaire. The survey was conducted anonymously for a period of six months. The survey was divided into five different sections: descriptive information about the respondent department, pre- and postoperative management, management of positioning in the operating room based on two fictional case examples, and quality management.

RESULTS

The response rate of our survey was 29.1 % (184/633). Nearly half of the departments (46.7 %) reported to have had one to five patients with positioning-related complications during the prior 12 months, and 29.1 % had experienced a legal dispute due to positioning-related complications. Departments with more than 50 gynecologic-oncological surgeries per year more often reported positioning-related complications (p=0.003). Standard operating procedures exist in almost every department for laparoscopic (97 %) and open surgery (95.1 %), respectively.

DISCUSSION

The high number of positioning-related complications throughout all departments of different healthcare levels underlines the relevance of this issue and supports the need for a prospective European registry for further analysis. Training and education for all staff members should be routinely implemented to reduce and prevent positioning-related complications.

Perioperative outcomes of women with and without class III obesity undergoing hysterectomy for endometrioid endometrial cancer: A population-based study

OBJECTIVE

Population-based data on perioperative complications among women with endometrial cancer and severe obesity are lacking. We evaluated 30-day complication rates among women with and without class III obesity (body mass index ≥ 40 kg/m²) undergoing primary surgical management for endometrioid endometrial cancer (EEC), and how outcomes differed according to surgical approach (open vs. minimally invasive).

METHODS

We performed a retrospective population-based cohort study of women with EEC undergoing hysterectomy in Ontario, Canada, between 2006 and 2015. We evaluated perioperative complications in the whole cohort, and in a 1:1 matched analysis using hard and propensity score matching to ensure similar distributions of patient, tumour, provider and institution-level factors between women with and without class III obesity (identified using a surgical billing code). The primary outcome of interest was the 30-day perioperative complication rate.

RESULTS

12,112 women met inclusion criteria; 2697 (22.3%) had class III obesity. We matched 2320 (86%) women with class III obesity to those without. The composite complication rate was significantly higher among women with class III obesity (23.2% vs. 18.4%, standardized mean difference [SMD] = 0.12), primarily due to wound infection/disruption (12.1% vs. 6.2%). There was no difference in outcomes for women with and without class III obesity when a minimally invasive approach was used.

CONCLUSIONS

Wound infection/disruption was increased for women with class III obesity compared to women without. Otherwise, perioperative complications were similar between the matched pairs. When minimally invasive approaches were used, women with class III obesity had a similar risk of complications as women without obesity.

Mini-open anterior approach focal cleaning combined with posterior internal fixation for thoracolumbar tuberculosis: Follow-up of 149 cases

OBJECTIVE

To investigate the clinical efficacy and safety of mini-open anterior approach focal cleaning combined with posterior internal fixation for thoracolumbar tuberculosis.

METHODS

A total of 149 patients with thoracolumbar tuberculosis were reviewed retrospectively and divided into 3 groups: mini-open anterior approach (group A), conventional anterior extraperitoneal approach (group B), and posterior approach (group C). After the operation, drainage tubes were routinely placed and the draining fluid was collected on the 4th day for the PCR detection of Mycobacterium tuberculosis (MTB), Mycobacterium tuberculosis DNA test (MTD), and Roche culture. Patients' surgical information, Cobb's angles, and postoperative complications were also compared.

RESULTS

There was no significant difference in operation time, blood loss, hospital stay, or preoperative Cobb's angle among three groups. There existed obvious differences in the postoperative Cobb's angle and incidence of postoperative complications between group A and group C, as well as group B and group C. There was no obvious difference in the positive rate of MTB among the three groups by rapid culture plus Roche culture test. However, statistically significant differences in the positive rate of MTB were found between group A and group C by PCR detection, and between group A and group B by MTD.

CONCLUSION

Mini-open anterior approach focal cleaning combined with posterior internal fixation resulted in small Cobb's angles, low incidence of postoperative complications and low positive rates of MTB, without increasing operation time, blood loss and hospital stay, rendering it as a safe and effective method to treat patients with thoracolumbar tuberculosis.

Age should not be a limiting factor in laparoscopic surgery: a prospective multicenter cohort study on quality of life after laparoscopic hysterectomy

Purpose

A prospective, multicenter cohort study was performed on the implementation of laparoscopic hysterectomy (LH) in the Netherlands. The aim of this study was to evaluate the impact of LH on quality of life (QOL) with respect to age up to 6 months postoperatively.

Patients and methods

Women with an indication for LH, either for benign conditions or early-stage low-risk endometrial cancer were included. QOL was measured before and 6 weeks and 6 months after surgery, using the 36-item Short Form Health Survey. Mean QOL values were compared to an unselected, female, Dutch reference population. A longitudinal linear mixed model was applied to assess changes in QOL over time after LH and to determine if in patients ≥65 years of age QOL scores were different.

Results

Data on 116 patients were available for analysis. The median age was 54 years at time of surgery (range 34-83) with an interquartile range of 43-65 years. Six months after LH, all QOL values were higher than before surgery and were equal to or higher than those of the reference population. Older women tend to score higher on QOL preoperatively, and these scores remain high postoperatively.

Conclusion

After LH, QOL improves. Older women report higher QOL values preoperatively and QOL is still high 6 months after the operation. Age does not confer a negative impact on QOL following LH and should not be the reason to refrain from laparoscopic surgery.
