Laparoscopy versus laparotomy for the management of endometrial carcinoma in morbidly obese patients: a prospective study

Surgical Treatment for Endometrial Cancer, Hysterectomy Performed via Minimally Invasive Routes Compared with Open Surgery: A Systematic Review and Network Meta-Analysis

Background: Total hysterectomy with bilateral salpingo-oophorectomy via minimally invasive surgery (MIS) has emerged as the standard of care for early-stage endometrial cancer (EC). Prior systematic reviews and meta-analyses have focused on outcomes reported solely from randomised controlled trials (RCTs), overlooking valuable data from non-randomised studies. This inaugural systematic review and network meta-analysis comprehensively compares clinical and oncological outcomes between MIS and open surgery for early-stage EC, incorporating evidence from randomised and non-randomised studies. Methods: This study was prospectively registered on PROSPERO (CRD42020186959). All original research of any experimental design reporting clinical and oncological outcomes of surgical treatment for endometrial cancer was included. Study selection was restricted to English-language peer-reviewed journal articles published 1 January 1995-31 December 2021. A Bayesian network meta-analysis was conducted. Results: A total of 99 studies were included in the network meta-analysis, comprising 181,716 women and 14 outcomes. Compared with open surgery, laparoscopic and robotic-assisted surgery demonstrated reduced blood loss and length of hospital stay but increased operating time. Compared with laparoscopic surgery, robotic-assisted surgery was associated with a significant reduction in ileus (OR = 0.40, 95% CrI: 0.17-0.87) and total intra-operative complications (OR = 0.38, 95% CrI: 0.17-0.75) as well as a higher disease-free survival (OR = 2.45, 95% CrI: 1.04-6.34). Conclusions: For treating early endometrial cancer, minimal-access surgery via robotic-assisted or laparoscopic techniques appears safer and more efficacious than open surgery. Robotic-assisted surgery is associated with fewer complications and favourable oncological outcomes.

Effect of two different modalities of hysterectomy on wound infection and wound dehiscence in obese patients

This research intended to investigate the influence of the operation of both kinds of hysterectomies in the risk of wound infection and the degree of wound dehiscence. Both of them were open field and laparoscope. In this research, we looked into four databases: PubMed, Web of Science, Embase and Cochrane Library. Research was conducted on various operative methods for hysterectomy in obese patients between 2000 and October 2023. Two independent investigators performed an independent review of the data, established the inclusion and exclusion criteria, and managed the results with Endnote software. It also evaluated the quality of the included literature. Finally, the data were analysed with RevMan 5.3. This study involved 874 cases, 387 cases received laparoscopy and 487 cases received open access operation. Our findings indicate that there is a significant reduction in the rate of post-operative wound infection among those who have received laparoscopy compared with who have received open surgical procedures (odds ratio [OR], 0.04; 95% confidence interval [CI], 0.01-0.15; p < 0.001); There was no statistical difference between the rate of post-operative wound dehiscence and those who received laparotomy compared with those who received open surgical procedures (OR, 0.33; 95% CI, 0.10-1.11; p = 0.07); The estimated amount of blood lost during the operation was less in the laparoscopy group compared with the open procedure (mean difference, -123.72; 95% CI, -215.16 to -32.28; p = 0.008). Generally speaking, the application of laparoscopy to overweight women who have had a hysterectomy results in a reduction in the expected amount of bleeding during surgery and a reduction in the risk of post-operative wound infections.

European Society of Gynaecological Oncology quality indicators for the surgical treatment of endometrial carcinoma

BACKGROUND

Quality of surgical care as a crucial component of a comprehensive multi-disciplinary management improves outcomes in patients with endometrial carcinoma, notably helping to avoid suboptimal surgical treatment. Quality indicators (QIs) enable healthcare professionals to measure their clinical management with regard to ideal standards of care.

OBJECTIVE

In order to complete its set of QIs for the surgical management of gynecological cancers, the European Society of Gynaecological Oncology (ESGO) initiated the development of QIs for the surgical treatment of endometrial carcinoma.

METHODS

QIs were based on scientific evidence and/or expert consensus. The development process included a systematic literature search for the identification of potential QIs and documentation of the scientific evidence, two consensus meetings of a group of international experts, an internal validation process, and external review by a large international panel of clinicians and patient representatives. QIs were defined using a structured format comprising metrics specifications, and targets. A scoring system was then developed to ensure applicability and feasibility of a future ESGO accreditation process based on these QIs for endometrial carcinoma surgery and support any institutional or governmental quality assurance programs.

RESULTS

Twenty-nine structural, process and outcome indicators were defined. QIs 1-5 are general indicators related to center case load, training, experience of the surgeon, structured multi-disciplinarity of the team and active participation in clinical research. QIs 6 and 7 are related to the adequate pre-operative investigations. QIs 8-22 are related to peri-operative standards of care. QI 23 is related to molecular markers for endometrial carcinoma diagnosis and as determinants for treatment decisions. QI 24 addresses the compliance of management of patients after primary surgical treatment with the standards of care. QIs 25-29 highlight the need for a systematic assessment of surgical morbidity and oncologic outcome as well as standardized and comprehensive documentation of surgical and pathological elements. Each QI was associated with a score. An assessment form including a scoring system was built as basis for ESGO accreditation of centers for endometrial cancer surgery.

Contemporary Incidence of Medical Inoperability in Clinical Stage I Endometrial Cancer

BACKGROUND

Minimally invasive surgical (MIS) staging is the standard treatment approach for clinical stage I endometrial cancer. Historical rates of inoperability in endometrial cancer are approximately 10%. Given surgical and medical advancements against increasing population obesity, we aimed to describe a contemporary incidence of medical inoperability in clinical stage I endometrial cancer.

PATIENTS AND METHODS

Patients diagnosed with clinical stage I endometrial cancer of any histology from April 2014 to December 2018 were included in this retrospective cohort study. The primary outcome, medical inoperability, was defined as (1) patients deemed inoperable by a gynecologic oncologist at initial consultation, (2) patients deemed inoperable during preoperative clearance, or (3) an aborted hysterectomy. Fisher's exact or χ², and Student's t-test or Wilcoxon rank sum test were used, as appropriate, for data analysis. Multivariable logistic regression was also employed.

RESULTS

Overall, 767 patients were included, of which 4.6% (35/767) were determined to be inoperable. The inoperable group had a higher body mass index (52.7 vs. 33.9, p < 0.001), and increased rates of diabetes (62.8%, 22/35 vs. 27.1%, 199/732, p < 0.001), coronary artery disease (31.4%, 11/35 vs. 7.1%, 52/732, p < 0.001), and hypertension (94.3%, 33/35 vs. 70.2%, 514/732, p < 0.001). Of those with attempted surgical staging, hysterectomy was aborted intraoperatively in 0.68% (5/737). The overall complication rate was 11.6% (86/737).

CONCLUSIONS

With maximal surgical effort and MIS, hysterectomy is possible in > 95% of patients with newly diagnosed endometrial cancer treated at a high-volume center. Complication rates were comparable to other trials evaluating the safety of MIS staging for endometrial cancer.

ESGO/ESTRO/ESP guidelines for the management of patients with endometrial carcinoma

A European consensus conference on endometrial carcinoma was held in 2014 to produce multidisciplinary evidence-based guidelines on selected questions. Given the large body of literature on the management of endometrial carcinoma published since 2014, the European Society of Gynaecological Oncology (ESGO), the European SocieTy for Radiotherapy & Oncology (ESTRO) and the European Society of Pathology (ESP) jointly decided to update these evidence-based guidelines and to cover new topics in order to improve the quality of care for women with endometrial carcinoma across Europe and worldwide. ESGO/ESTRO/ESP nominated an international multidisciplinary development group consisting of practicing clinicians and researchers who have demonstrated leadership and expertise in the care and research of endometrial carcinoma (27 experts across Europe). To ensure that the guidelines are evidence-based, the literature published since 2014, identified from a systematic search was reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the development group. The guidelines are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines were reviewed by 191 independent international practitioners in cancer care delivery and patient representatives. The guidelines comprehensively cover endometrial carcinoma staging, definition of prognostic risk groups integrating molecular markers, pre- and intra-operative work-up, fertility preservation, management for early, advanced, metastatic, and recurrent disease and palliative treatment. Principles of radiotherapy and pathological evaluation are also defined.

Comparing laparoscopy and laparotomy procedures in the radical hysterectomy surgery for endometrial cancer: a basic review

Gynecological cancers especially endometrial cancer have put a huge burden on health care systems in different societies. In this regard, different studies have evaluated screening, diagnosis and treatments of endometrial cancer. Different survival rates, prognosis and recurrence rates have been reported by variable treatment methods. Laparotomy and laparoscopic radical hysterectomy (RH and LRH) are nowadays two most common surgical methods for endometrial cancer. In this systematic review, we investigated all article comparing two treatment techniques regarding RH and LRH in women with endometrial cancer who were classified as International Federation of Gynecology and Obstetrics (FIGO) stage I to III. Data regarding to blood loss and transfusion rate, operative time, duration of hospital stay, complications as intraoperative and postoperative, mean nodules counts, recurrent rate, adjuvant therapy were collected and analyzed. After reviewing five cohort studies, we indicated that laparoscopic procedures were better than laparotomy for managing endometrial cancer because the duration of hospitalization, blood loss and intraoperative and postoperative complications in laparoscopy procedure were lower than laparotomy procedures.

Outcomes of robotic surgery performed in patients with high BMI class: experience by a single surgeon

BACKGROUND

Advanced laparoscopic procedures have been shown to be safe in patients with high Body Mass Index (BMI), but conversion rates remain high. This analysis aimed to evaluate the feasibility and clinical outcomes in terms of long- and short-term complications, pain relief of robotic surgery in morbidly obese patients.

METHODS

Patients with BMI class I-II-III with endometrial cancer or hyperplasia were treated with robotic hysterectomy (RH). Patients' characteristics, operating room time (OT), type of surgery, length of hospital stay, and incidence of complications were recorded. Records were reviewed for demographic data, medical/surgical history and comorbidities, perioperative findings and outcomes, as well as long-term complications and recurrences. Regarding stage, according to 2009 FIGO, 26 of cases were IA, while eight and five of cases were, respectively, IB, II stage.

RESULTS

A total of 87 consecutive RH were analyzed. The more frequent comorbidity was hypertension. Twenty percent of the patients had multiple comorbidities (>2). The mean age was 63±10 years, with a mean BMI of 36±8.2 kg/m2. The more frequent BMI group treated was II class. The median OT was 114 minutes (range: 49-270). According to the Dindo Classification, there were no differences in major or minor complications between the 3 BMI classes. This series had a median follow-up of 60 months (range: 8-96) with an overall survival rate of 100%. The RRH+PLH was feasible and pathology confirmed the adequacy of the surgical specimen, with a median count of 20 nodes.

CONCLUSIONS

Our data support the adoption of the surgical management of the morbidly obese patient. Although short term complication rates are higher with increasing obesity (II-III class), a majority of procedures can still be completed with minimally invasive approach.

Comparison of Laparoscopy and Laparotomy in Early-Stage Endometrial Cancer: Early Experiences from a Developing Country

After minimally invasive surgery gained popularity in gynecology, laparoscopic operations became widespread among oncologic operations. However, more studies evaluating experiences of oncologic surgeons during the learning period of laparoscopy are needed. To compare the surgical outcomes and perioperative complications of laparoscopic surgery and laparotomy in the treatment of early-stage endometrioid endometrial cancer patients, we retrospectively investigated patients who underwent surgery due to endometrial cancer at our institution between 2014 and 2018. Early-stage (stage I) endometrioid endometrial cancer patients were included in the study. Operative times, length of hospital stay, extracted pelvic lymph nodes, perioperative complications, and blood loss were compared. A total of 128 patients were treated for stage I endometrial cancer during the study period. Sixty-two patients (48.4%) underwent laparoscopic surgery, and 66 (51.6%) patients underwent laparotomy. Median operation time and pelvic lymph node count in the laparotomy and laparoscopy groups did not demonstrate statistically significant differences. However, the length of hospital stay, estimated blood loss, and perioperative complication rate were lower in the laparoscopic surgery group. Laparoscopic surgery in early-stage endometrial cancer may be performed with less blood loss, shorter duration of hospital stays, and similar lymph node counts compared to laparotomic surgery.

Laparoscopic and robotic hysterectomy in endometrial cancer patients with obesity: a systematic review and meta-analysis of conversions and complications

OBJECTIVE DATA

Robotic assistance may facilitate completion of minimally invasive hysterectomy, which is the standard of care for the treatment of early-stage endometrial cancer, in patients for whom conventional laparoscopy is challenging. The aim of this systematic review was to assess conversion to laparotomy and perioperative complications after laparoscopic and robotic hysterectomy in patients with endometrial cancer and obesity (body mass index, ≥30 kg/m²).

STUDY

We systematically searched MEDLINE, EMBASE, and Evidence-Based Medicine Reviews (January 1, 2000, to July 18, 2018) for studies of patients with endometrial cancer and obesity (body mass index, ≥30 kg/m²) who underwent primary hysterectomy.

STUDY APPRAISAL AND SYNTHESIS METHODS

We determined the pooled proportions of conversion, organ/vessel injury, venous thromboembolism, and blood transfusion. We assessed risk of bias with the Institute of Health Economics Quality Appraisal Checklist for single-arm studies, and Newcastle-Ottawa Quality Scale for double-arm studies.

RESULTS

We identified 51 observational studies that reported on 10,800 patients with endometrial cancer and obesity (study-level body mass index, 31.0-56.3 kg/m²). The pooled proportions of conversion from laparoscopic and robotic hysterectomy were 6.5% (95% confidence interval, 4.3-9.9) and 5.5% (95% confidence interval, 3.3-9.1), respectively, among patients with a body mass index of ≥30 kg/m², and 7.0% (95% confidence interval, 3.2-14.5) and 3.8% (95% confidence interval, 1.4-9.9) among patients with body mass index of ≥40 kg/m². Inadequate exposure because of adhesions/visceral adiposity was the most common reason for conversion for both laparoscopic (32%) and robotic hysterectomy (61%); however, intolerance of the Trendelenburg position caused 31% of laparoscopic conversions and 6% of robotic hysterectomy conversions. The pooled proportions of organ/vessel injury (laparoscopic, 3.5% [95% confidence interval, 2.2-5.5]; robotic hysterectomy, 1.2% [95% confidence interval, 0.4-3.4]), venous thromboembolism (laparoscopic, 0.5% [95% confidence interval, 0.2-1.2]; robotic hysterectomy, 0.5% [95% confidence interval, 0.1-2.0]), and blood transfusion (laparoscopic, 2.8% [95% confidence interval, 1.5-5.1]; robotic hysterectomy, 2.1% [95% confidence interval, 1.6-3.8]) were low and not appreciably different between arms.

CONCLUSION

Robotic and laparoscopic hysterectomy have similar rates perioperative complications in patients with endometrial cancer and obesity, but robotic hysterectomy may reduce conversions because of positional intolerance in patients with morbid obesity. Existing literature is limited by selection and confounding bias, and randomized trials are needed to inform practice standards in this population.

Exploring the role of obesity and overweight in predicting postoperative outcome of abdominal surgery in a sub-Saharan African setting: a prospective cohort study

Objective

Current literature on the role of excess weight in predicting surgical outcome is controversial. In sub-Saharan Africa, there is extreme paucity of data regarding this issue in spite of the increasing rates of obesity and overweight in the region. This prospective cohort study, carried out over a period of 4 months at Limbe Regional Hospital in the Southwest region of Cameroon, assessed 30-day postoperative outcome of abdominal surgery among consecutive adults with body mass index (BMI) ≥ 25 kg/m². Adverse postoperative events were reported as per Clavien–Dindo classification.

Results

A total of 103 patients were enrolled. Of these, 68.9% were female. The mean age was 38.2 ± 13.7 years. Sixty-four (62.1%) of the patients were overweight and the mean BMI was 29.2 ±4.3 kg/m². The physical status scores of the patients were either I or II. Appendectomy, myomectomy and hernia repair were the most performed procedures. The overall complication rate was 13/103 (12.6%), with 61.5% being Clavien–Dindo grades II or higher. From the lowest to the highest BMI category, there was a significant increase in the proportion of patients with complications; 25–29.9 kg/m²: 6.25%, 30–34.9 kg/m²: 18.75%, 35–39.9 kg/m²: 25.0%, and ≥ 40 kg/m²: 66.70%; p = 0.0086.

Considerations for minimally invasive gynecologic surgery in obese patients

PURPOSE OF REVIEW

The purpose is to review the key anatomical and physiological changes in obese patients and their effects on preoperative, intraoperative, and postoperative care and to highlight the best practices to safely extend minimally invasive approaches to obese patients and provide optimal surgical outcomes in this high-risk population.

RECENT FINDINGS

Minimally invasive surgery is safe, feasible, and cost-effective for obese patients. Obesity is associated with anatomical and physiological changes in almost all organ systems, which necessitates a multimodal approach and an experienced, multidisciplinary team. Preoperative counseling, evaluation, and optimization of medical comorbidities are critical. The optimal minimally invasive approach is primarily determined by the patient's anatomy and pathology. Specific intraoperative techniques and modifications exist to maximize surgical exposure and panniculus management. Postoperatively, comprehensive medical management can help prevent common complications in obese patients, including hypoxemia, venous thromboembolism, acute kidney injury, hyperglycemia, and prolonged hospitalization.

SUMMARY

Given significantly improved patient outcomes, minimally invasive approaches to gynecological surgery should be considered for all obese patients with particular attention given to specific perioperative considerations and appropriate referral to an experienced minimally invasive surgeon.

Complications in gynecological minimal-access oncosurgery

Complications are the limiting factors of all surgeries. More than performing the actual surgery, learning how to avoid complications before, during, and after surgery is the most important task of every surgeon. Severe complications can lead to patient death. Complications such as ureterovaginal fistulas, resulting from <2 s of inattentive preparation, can lead to years of hardship, suffering, accusation, and litigation. Excellent surgery is about performing the right surgery for the right patient without any complications. Minimally invasive surgery in complex cases is technically challenging. This article details the major causes of complications in laparoscopy for the gynecologic cancer patient and present strategies for prevention, early detection, and intra- and postoperative management.
