RESUMO
BACKGROUND: Pelvic exenteration (PE) is often the only curative treatment option for selected locally advanced and locally recurrent colorectal cancer associated with significant morbidity. Open and laparoscopic approaches were accepted for this procedure. OBJECTIVE: This study aimed to examine the Chinese patient-reported outcomes (PROs) and health-related quality of life (HRQoL) after PE. METHODS: A total of 122 enrolled participants were asked to complete PROs at baseline and 1, 3, 6, 9 and 12 months after PE. PROs included seven symptoms from the National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). The HRQoL was assessed using the Functional Assessment of Cancer Therapy-Colorectal (FACT-C). RESULTS: The overall postoperative complication rate was 41.0%. Patients experienced lower physical and functional well-being and FACT-C 1 month after surgery, then gradually recovered. The FACT-C score returned to baseline 9 months after surgery. Social and emotional well-being did not show signs of recovery until 6 months after the surgical procedure, and did not fully return to baseline until 12 months post-surgery. Symptom rates of insomnia, anxiety, discouragement, and sadness (composite score >0) did not improve significantly from baseline until 12 months after surgery. CONCLUSIONS: PE is a feasible treatment choice for locally advanced primary and recurrent colorectal cancer. Social, psychological, and emotional recovery in the Chinese population after PE tends to be slower compared with the physical condition.
RESUMO
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.

BACKGROUND: Recently, with the advancement of medical technology, the postoperative morbidity of pelvic exenteration (PE) has gradually decreased, and it has become a curative treatment option for some patients with recurrent gynecological malignancies. However, more evidence is still needed to support its efficacy. This study aimed to explore the safety and long-term survival outcome of PE and the feasibility of umbilical single-port laparoscopic PE for gynecologic malignancies in a single medical center in China. PATIENTS AND METHODS: PE for gynecological cancers except for ovarian cancer conducted by a single surgical team in Sun Yat-sen University Cancer Center between July 2014 and December 2019 were included and the data were retrospectively analyzed. RESULTS: Forty-one cases were included and median age at diagnosis was 53 years. Cervical cancer accounted for 87.8% of all cases, and most of them received prior treatment (95.1%). Sixteen procedures were performed in 2016 and before, and 25 after 2016. Three anterior PE were performed by umbilical single-site laparoscopy. The median operation time was 460 min, and the median estimated blood loss was 600 ml. There was no perioperative death. The years of the operations was significantly associated with the length of the operation time (P = 0.0018). The overall morbidity was 52.4%, while the severe complications rate was 19.0%. The most common complication was pelvic and abdominal infection. The years of surgery was also significantly associated with the occurrence of severe complication (P = 0.040). The median follow-up time was 55.8 months. The median disease-free survival (DFS) was 17.9 months, and the median overall survival (OS) was 25.3 months. The 5-year DFS was 28.5%, and the 5-year OS was 30.8%. CONCLUSION: PE is safe for patient who is selected by a multi-disciplinary treatment, and can be a curative treatment for some patients. PE demands a high level of experience from the surgical team. Umbilical single-port laparoscopy was a technically feasible approach for APE, meriting further investigation.

OBJECTIVES: To compare perioperative outcomes in patients undergoing pelvic exenteration for gynecologic malignancies before and after implementation of Enhanced Recovery After Surgery (ERAS) protocols. METHODS: We performed an institutional retrospective cohort study of patients undergoing pelvic exenteration for gynecologic malignancies before (1/1/2006-12/30/2014) and after (1/1/2015-6/30/2023) ERAS implementation. We described ERAS compliance rates. We compared outcomes up to 60 days post-exenteration. Complication grades were defined by the Clavien-Dindo system. RESULTS: Overall, 105 women underwent pelvic exenteration; 74 (70.4%) in the pre-ERAS and 31 (29.5%) in the ERAS cohorts. There were no differences between cohorts in age, body mass index, race, primary disease site, type of exenteration, urinary diversion, or vaginal reconstruction. All patients had complications, with at least one grade II+ complication in 94.6% of pre-ERAS and 90.3% of ERAS patients. The ERAS cohort had more grade I-II gastrointestinal (61.3% vs 21.6%, p < 0.001) and hematologic (61.3% vs 36.5%, p = 0.030) and grade III-IV renal (29.0% vs 12.2%, p = 0.048) and wound (45.2% vs 18.9%, p = 0.008) complications compared to the pre-ERAS cohort. ERAS patients had a higher rate of ileus (38.7% vs 10.8%, p = 0.002), urinary leak (22.6% vs 5.4%, p = 0.014), pelvic abscess (35.5% vs 10.8%, p = 0.005), postoperative bleeding requiring intervention (61.3% vs 28.4%, p = 0.002), and readmission (71.4% vs 46.5%, p = 0.025). Median ERAS compliance was 60%. CONCLUSIONS: Pelvic exenteration remains a morbid procedure, and complications were more common in ERAS compared to pre-ERAS cohorts. ERAS protocols should be optimized and tailored to the complexity of pelvic exenteration compared to standard gynecologic oncology ERAS pathways.
RESUMO
OBJECTIVE: To compare perioperative morbidity, functional and quality-of-life (QoL) outcomes in patients with partial cystectomy vs radical cystectomy as part of pelvic exenteration. PATIENTS AND METHODS: Retrospective analysis of a prospectively maintained database of pelvic exenteration patients (1998-2021) was conducted in a single centre. Study outcomes included postoperative complications, quality-of-life, functional and stoma-related outcomes. The 36-item Short-Form Health Survey Physical and Mental Health Components, Functional Assessment of Cancer Therapy-Colorectal questionnaires and Distress Thermometer were available pre- and postoperatively. QoL outcomes were compared at the various time points. Stoma embarrassment and care scores were compared between patients with a colostomy, urostomy, and both. RESULTS: Urological complications were similar between both groups, but patients with partial cystectomy experienced less wound-related complications. Overall, 34/81 (42%) partial cystectomy patients reported one or more long-term voiding complication (i.e., incontinence [17 patients], frequency [six], retention [three], high post-voiding residuals [10], permanent suprapubic catheter/indwelling catheter [14], recurrent urinary tract infection [nine], percutaneous nephrostomy [three], progression to urostomy [three]). The QoL improved following surgery in both the partial and radical cystectomy groups, differences between cohorts were not significant. Patients with two stomas reported higher embarrassment scores than patients with one stoma, although this did not result in more difficulties in stoma care. CONCLUSIONS: Partial cystectomy patients have fewer postoperative wound-related complications than radical cystectomy patients, but often experience long-term voiding issues. The QoL outcomes are similar for both cohorts, with significant improvement following surgery.

BACKGROUND: Pelvic exenteration (PE) is an extensive surgical treatment reserved for advanced or recurrent pelvic neoplasms, with potential impacts on patients' quality of life (QoL) poorly referenced in the literature. OBJECTIVES: This study aimed to evaluate QoL outcomes among three types of PE. METHODS: A cross-sectional study assessed 106 patients divided into anterior PE (APE), posterior PE (PPE), or total PE (TPE) groups. QoL was measured using e short form 36 version 2 (SF-36) and the European Organization for Research and Treatment of Cancer QoL Quality of Life Questionnaire Core 30 (QLQ-C30) QoL questionnaires. Descriptive and inferential analyses compared questionnaire scores. RESULTS: The findings unveiled a balance among the three groups concerning demographic variables and comorbidities, with the exception of a male predominance in the APE and TPE cohorts. Notably, the APE group exhibited elevated scores in overall health (assessed via SF-36) and social functioning and diarrhea domains (assessed via QLQ-C30). Moreover, in terms of the fatigue and nausea/vomiting domains (assessed via QLQ-C30), the APE group demonstrated superior QoL compared to the PPE group. Conversely, the PPE group manifested a notably lower QoL in the constipation domain (assessed via QLQ-C30) compared to the other two groups. Additionally, disease recurrence was significantly associated with diminished QoL across multiple domains. CONCLUSION: APE patients exhibited better QoL than PPE and TPE groups, with disease recurrence adversely affecting QoL.
RESUMO
PURPOSE: Improvements in neoadjuvant therapy for locally advanced cT4 rectal cancer have led to improved tumour response and thus a variety of suitable management strategies. The aim of this study was to report management and outcomes of patients with cT4 rectal cancer undergoing a spectrum of treatment strategies from organ preservation (OP) to pelvic exenteration (PE). METHODS: Patients who underwent elective treatment for cT4 rectal cancer between 2016 and 2021 were included. All patients were treated with curative intent. Surgical management was adapted to tumour response. Kaplan-Meier curves were generated to compare 3-year overall survival (3y-OS), local recurrence (3y-LR) and distant metastases (3y-DM) between different strategies. RESULTS: Among 152 patients included, 13 (8%) underwent OP, 71 (47%) TME and 68 (45%) APR/PE. The median follow-up was 31.3 months. Patients undergoing OP had a lower tumour pretreatment (p < 0.001). Compared to patients with TME, those with APR/PE had a higher rate of ypT4 (p = 0.001) with a lower R0 rate (p = 0.044). The 3y-OS and 3y-DM were 78% and 15.1%, respectively, without significant differences. The 3y-LR was 6.6%, and patients with OP had a significantly worse 3y-local regrowth compared to 3y-LR in patients with TME and APR/PE (30.2% vs. 5.4% vs. 2%, p = 0.008). CONCLUSION: cT4 tumours may be suitable for the full spectrum of rectal cancer management from organ preservation to pelvic exenteration depending on tumour response to neoadjuvant therapy. However, careful attention is required in OP as local regrowth in up to 30% of cases reinforces the need for sustained active surveillance in Watch&Wait programmes.

PURPOSE: Surgical techniques and the prognosis of posterior pelvic exenteration for locally advanced primary rectal cancer in female patients pose challenges that need to be addressed. Therefore, we investigated the short-term and survival outcomes of posterior pelvic exenteration in female patients using a novel Peking classification. METHODS: We retrospectively analysed a prospective database from China PelvEx Collaborative across three tertiary referral centres. A total of 172 patients who underwent combined resection for locally advanced primary rectal cancer were classified based on four subtypes (PPE-I [64/172], PPE-II [68/172], PPE-III [21/172], and PPE-IV [19/172]) according to the Peking classification; perioperative characteristics and short-term and oncological outcomes were analysed. RESULTS: Differences were significant among the four groups regarding colorectal reconstruction (p < 0.001), perineal reconstruction (p < 0.001), in-hospital complications (p < 0.05), and urinary retention (p < 0.05). The R0 resection rates for PPE-I, PPE-II, PPE-III, and PPE-IV were 90.6%, 89.7%, 90.5%, and 89.5%, respectively. The 5-year overall survival rates of the PPE-I, PPE-II, PPE-III, and PPE-IV groups were 73.4%, 68.8%, 54.7%, and 37.3%, respectively. Correspondingly, their 5-year disease-free survival rates were 76.0%, 62.5%, 57.7%, and 43.1%, respectively. Notably, the PPE-IV group demonstrated the lowest 5-year overall survival rate (p < 0.001) and 5-year disease-free survival rate (p < 0.001). CONCLUSION: The Peking classification can aid in determining suitable surgical techniques and conducting prognostic assessments in female patients with locally advanced primary rectal cancer.

Pelvic exenteration (PE) is a technically challenging surgical procedure. More recently, quality of life and survivorship following PEs are being increasingly acknowledged as important patient outcomes. This includes evaluating major long-term complications such as hernias, defined as the protrusion of internal organs through a facial defect (The PelvEx Collaborative in Br J Surg 109:1251-1263, 2022), for which there is currently limited literature. The aim of this paper is to ascertain the incidence and risk factors for postoperative hernia formation among our PE cohort managed at a quaternary centre. METHOD: A retrospective cohort study examining hernia formation following PE for locally advanced rectal carcinoma and locally recurrent rectal carcinoma between June 2010 and August 2022 at a quaternary cancer centre was performed. Baseline data evaluating patient characteristics, surgical techniques and outcomes was collated among a PE cohort of 243 patients. Postoperative hernia incidence was evaluated via independent radiological screening and clinical examination. RESULTS: A total of 79 patients (32.5%) were identified as having developed a hernia. Expectantly, those undergoing flap reconstruction had a lower incidence of postoperative hernias. Of the 79 patients who developed postoperative hernias, 16.5% reported symptoms with the most common symptom reported being pain. Reintervention was required in 18 patients (23%), all of which were operative. CONCLUSION: This study found over one-third of PE patients developed a hernia postoperatively. This paper highlights the importance of careful perioperative planning and optimization of patients to minimize morbidity.

BACKGROUND: Empty Pelvis Syndrome, subsequent to the removal of pelvic organs, results in the descent of the small bowel into an inflamed pelvic cavity, leading to the formation of adhesions and subsequent small bowel obstruction. However, no effective measures have been previously described. OBJECTIVE: Describe a simple and autologous solution to prevent "Empty Pelvis Syndrome," small bowel obstruction, and adhesions by utilizing the cecum to occlude the pelvis. DESIGN: Mobilization of the right colon to lower the cecum into the pelvic cavity to occlude the superior pelvic ring to some degree and changing the direction of the terminal ileum. SETTINGS: Hospital Universitario Fundación Jiménez Díaz, Department of General Surgery, Colorectal Service. PATIENTS: Eight anonymized patients were included in this study, each with varying colorectal pathologies. Patients were above 18 years old. MAIN OUTCOME MEASURES: Percent of blockage of the superior pelvic ring produced by the descended cecum recorded in percentage; the amount of small intestine descended past the superior pelvic ring recorded in cm. RESULTS: The mobilization of the cecum achieved partial occlusion of the superior pelvic ring. The descent of the small bowel beyond this landmark ranged from 0 to 4.9 cm. LIMITATIONS: Given the small number of patients included in this study, these results cannot be generalized to the whole of the population. A bladder emptying protocol prior to CT scans was not implemented, resulting in variations in measurements among patients. CONCLUSION: The cecum-to-pelvis technique is a simple method that can serve as an autologous solution to EPS (enteropelvic fistula) and help reduce postoperative complications such as SBO (small bowel obstruction) and adhesions. It is not essential to completely occlude the superior pelvic ring to achieve successful outcomes.

AIM: Surgery for complex colorectal cancer is elaborate: preoperative assessment, patient selection, radiological interpretation, operative strategy, operative technical skills, operative standardization, postoperative care and management of complications are all critical components. Given this complexity, training that encompasses all these crucial aspects to generate suitably edified surgeons is essential. To date, no curriculum exists to guide training in advanced and recurrent pelvic malignancy, particularly for complex colorectal cancer. Such a curriculum would potentially offer numerous advantages, not only for individual surgeons but also for research, governance, international collaboration and benchmarking. The aim of this study was to design and develop a framework for a curriculum for fellowship training in complex colorectal cancer that encompasses pelvic exenteration surgery. METHOD: Kern described a six-step method for curriculum design that is now widely adopted in medical education. Our study utilizes steps 1-4 of Kern's method to develop a syllabus and assessment framework for curriculum development for fellowship training in complex colorectal cancer encompassing pelvic exenteration. A literature review was conducted to address step 1, followed by targeted needs assessment in step 2 by conducting focus groups with trainees, fellows and experts to identify learning needs and goals with objective setting for step 3. An expert consensus group then voted on these recommendations and developed educational strategy recommendations as step 4. For the purposes of brevity, 'pelvic exenteration' in the text is taken to also encompass extended and multivisceral resections that fall under the remit of complex [colorectal] cancer. RESULTS: Step 1 of Kern's method identified a gap in the literature on curricula in complex cancer surgery. Step 2 identified key areas regarded as learning needs by trainees, including anatomy, hands-on experience and case volume. Step 3 defined the goals and objectives of a fellowship curriculum, defined in six domains including theoretical knowledge, decision-making, technical skills, postoperative management and continuing professional development. Finally, as a prelude to stages 5 and 6, a strategy for implementation and for feedback and assessment was agreed by an expert consensus meeting that defined case volume (a minimum of 20 pelvic exenteration operations within a fellowship period) and coverage of this syllabus with derived metrics. CONCLUSIONS: Our working group has developed a curriculum framework for advanced fellowship training in complex cancer in the UK. Validation is needed through implementation, and affirmation of its utility, both nationally and internationally, must be sought.
RESUMO
AIM: The aim of this study was to investigate the role of human factors in pelvic exenteration and how team performance is optimized in the preoperative, intraoperative and postoperative phases. METHOD: Qualitative analysis of focus groups was used to capture authentic human interactions that reflect real-world multiprofessional performance. Theatre teams were treated as clusters, with a particular focus group containing participants who worked together regularly. RESULTS: Three focus groups were conducted. Four themes emerged - driving force, technical skills, nontechnical skills and operational aspects - with a total of 16 subthemes. Saturation was reached by group 2, with no new subthemes emerging after this. There was some interaction between the themes and the subthemes. Broadly speaking, driving force led to the development of specialised technical skills and nontechnical skills, which were operationalized into successful service through operational aspects. CONCLUSION: This study of teams performing pelvic exenteration is the first in the field using this methodology. It has generated rich qualitative data with authentic insights into the pragmatic aspects of developing and delivering a service. In addition, it shows how the themes are connected or 'coupled' in a network, for example technical and non-technical skills. In a complex system, 'tight coupling' leads to both high performance and adverse events. In this paper, we report the qualitative aspects of high performance by pelvic exenteration teams in a complex sociotechnical system, which depends on tight coupling of several themes.

AIM: There is increasing research interest in pelvic exenteration for locally advanced and recurrent rectal cancer. Heterogeneity in outcome reporting can prevent meaningful interpretation and valid synthesis of pooled data and meta-analyses. The aim of this study was to assess homogeneity in outcome measures in the current pelvic exenteration literature. METHOD: MEDLINE, Embase, CENTRAL, CINAHL and Scopus databases were searched from 1990 to 25 April 2023 to identify studies reporting outcomes of pelvic exenteration for locally advanced or recurrent rectal cancer. All reported outcomes were extracted, merged with those of similar meaning and assigned a domain. RESULTS: Of 4137 abstracts screened, 156 studies met the inclusion criteria. A total of 2765 outcomes were reported, of which 17% were accompanied by a definition. There were 1157 unique outcomes, merged into 84 standardized outcomes and assigned one of seven domains. The most reported domains were complications (147 studies, 94%), survival (127, 81%) and surgical outcomes (123, 79%). Resection margins were reported in 122 studies (78%): the definition of a clear resection margin was not provided in 45 studies (37%), it was unclear in 11 studies (9%) and not specified beyond microscopically 'clear' or 'negative' in 31 (28%). Measurements of 2, 1, 0.5 mm and any healthy tissue were all used to define R0 margins. CONCLUSION: There is significant heterogeneity in outcome measurement and reporting in the current pelvic exenteration literature, raising concerns about the validity of comparative or collaborative studies between centres and meta-analyses. Coordinated international collaboration is required to define core outcome sets and benchmarks.

BACKGROUND: Pelvic exenteration (PE) is the last resort for achieving a complete cure for pelvic cancer; however, it is burdensome for patients. Minimally invasive surgeries, including robot-assisted surgery, have been widely used to treat malignant tumors and have also recently been used in PE. This study aimed to evaluate the safety and efficacy of robot-assisted PE (RPE) by comparing the outcomes of open PE (OPE) with those of conventional laparoscopic PE (LPE) for treating pelvic tumors. METHODS: Following the ethics committee approval, a multicenter retrospective analysis of patients who underwent pelvic exenteration between January 2012 and October 2022 was conducted. Data on patient demographics, tumor characteristics, and perioperative outcomes were collected. A 1:1 propensity score-matched analysis was performed to minimize group selection bias. RESULTS: In total, 261 patients met the study criteria, of whom 61 underwent RPE, 90 underwent OPE, and 110 underwent LPE. After propensity score matching, 50 pairs were created for RPE and OPE and 59 for RPE and LPE. RPE was associated with significantly less blood loss (RPE vs. OPE: 408 mL vs. 2385 ml, p < 0.001), lower transfusion rate (RPE vs. OPE: 32% vs. 82%, p < 0.001), and lower rate of complications over Clavien-Dindo grade II (RPE vs. OPE: 48% vs. 74%, p = 0.013; RPE vs. LPE: 48% vs. 76%, p = 0.002). CONCLUSION: This multicenter study suggests that RPE reduces blood loss and transfusion compared with OPE and has a lower rate of complications compared with OPE and LPE in patients with locally advanced and recurrent pelvic tumors.

There have been no reported cases of neuroendocrine carcinoma (NEC) of the cervix with pagetoid spread (Pag-S). A 44-year-old woman came to our department because of abnormal cytology that persisted immediately after a radical hysterectomy for NEC of the cervix. A mapping biopsy in a large area from the vaginal wall to the vulva revealed that synaptophysin/Ki-67-positive tumor cells were scattered within the epithelium in multiple areas, suggesting a wide Pag-S of NEC. Because tumor cells were found beyond the vaginal wall, the anterior pelvic exenteration was performed. Since we could pathologically confirm the complete resection and no distant metastases were detected, no adjuvant therapy was performed. Four years have passed since the initial treatment without any tumor recurrence. It is known that the prognosis of NEC of the cervix that invades beyond the cervix is poor; however, if there is a Pag-S pattern, a radical surgical treatment can be considered.

PURPOSE: While laparoscopic pelvic exenteration reduces intraoperative blood loss, dorsal venous complex bleeding during this procedure causes issues. We previously introduced a method to transect the dorsal venous complex and urethra using a linear stapler during cooperative laparoscopic and transperineal endoscopic (two-team) pelvic exenteration. The present study assessed its effectiveness in reducing intraoperative blood loss by comparing it with conventional laparoscopic pelvic exenteration. METHODS: This retrospective cohort study was conducted at a Japanese tertiary referral center. Eleven cases of two-team laparoscopic pelvic exenteration with staple transection of the dorsal venous complex (T-PE group) were compared to 25 cases of conventional laparoscopic pelvic exenteration (C-PE group). The primary outcome measure was intraoperative blood loss. RESULTS: There were no significant between-group differences in patient background. The mean intraoperative blood loss was significantly lower in the T-PE group than in the C-PE group (200 vs. 850 mL, p = 0.01). The respective mean operation time, postoperative complication rate, and R0 resection rate were similar between the T-PE and C-PE groups (636 min vs. 688 min, p = 0.36; 36% vs. 44%, p = 0.65; 100% vs. 100%, p = 1.00). CONCLUSIONS: Two-team laparoscopic pelvic exenteration with staple transection of the dorsal venous complex reduced intraoperative blood loss from the dorsal venous complex in a technically safe and oncologically feasible manner.

BACKGROUND: Large tissue defects following pelvic exenteration (PE) fill with fluid and small bowel, leading to the empty pelvis syndrome (EPS). EPS causes a constellation of complications including pelvic sepsis and reduced quality of life. EPS remains poorly defined and cannot be objectively measured. Pathophysiology of EPS is multifactorial, with increased pelvic dead space potentially important. This study aims to describe methodology to objectively measure volumetric changes relating to EPS. METHODS: The true pelvis is defined by the pelvic inlet and outlet. Within the true pelvis there is physiological pelvic dead space (PDS) between the peritoneal reflection and the inlet. This dead space is increased following PE and is defined as the exenteration pelvic dead space (EPD). EPD may be reduced with pelvic filling and the volume of filling is defined as the pelvic filling volume (PFV). PDS, EPD, and PFV were measured intraoperatively using a bladder syringe, and Archimedes' water displacement principle. RESULTS: A patient undergoing total infralevator PE had a PDS of 50 ml. A rectus flap rendered the pelvic outlet watertight. EPD was then measured as 540 ml. Therefore there was a 10.8-fold increase in true pelvis dead space. An omentoplasty was placed into the EPD, displacing 130 ml; therefore, PFV as a percentage of EPD was 24.1%. CONCLUSIONS: This is the first reported quantitative assessment of pathophysiological volumetric changes of pelvic dead space; these measurements may correlate to severity of EPS. PDS, EPD, and PFV should be amendable to assessment based on perioperative cross-sectional imaging, allowing for potential prediction of EPS-related outcomes.

OBJECTIVES: The aim of this study was to analyze morbidity and survival after pelvic exenteration for gynecologic malignancies and evaluate prognostic factors influencing postoperative outcome. METHODS: We retrospectively reviewed all patients who underwent a pelvic exenteration at the departments of gynecologic oncology of three tertiary care centers in the Netherlands, the Leiden University Medical Centre, the Amsterdam University Medical Centre, and the Netherlands Cancer Institute, during a 20-year period. We determined postoperative morbidity, 2- and 5-year overall survival (OS) and 2- and 5-year progression free survival (PFS), and investigated parameters influencing these outcomes. RESULTS: A total of 90 patients were included. The most common primary tumor was cervical cancer (n = 39, 43.3%). We observed at least one complication in 83 patients (92%). Major complications were seen in 55 patients (61%). Irradiated patients had a higher risk of developing a major complication. Sixty-two (68.9%) required ≥1 readmission. Re-operation was required in 40 patients (44.4%). Median OS was 25 months and median PFS was 14 months. The 2-year OS rate was 51.1% and the 2-year PFS rate was 41.5%. Tumor size, resection margins and pelvic sidewall involvement had a negative impact on OS (HR = 2.159, HR = 2.376, and HR = 1.200, respectively). Positive resection margins and pelvic sidewall involvement resulted in decreased PFS (HR = 2.567 and HR = 3.969, respectively). CONCLUSION: Postoperative complications after pelvic exenteration for gynecologic malignancies are common, especially in irradiated patients. In this study, a 2-year OS rate of 51.1% was observed. Positive resections margins, tumor size, and pelvic sidewall involvement were related to poor survival outcomes. Adequate selection of patients who will benefit from pelvic exenteration is important.

OPINION STATEMENT: Pelvic exenteration is a radical surgery, but oftentimes, it is the last curative option for patients with recurrent gynecologic malignancies who have exhausted more conservative therapies. Mortality and morbidity outcomes have improved over time, but there are still significant peri-operative risks. Considerations before pursing pelvic exenteration must include the likelihood of oncologic cure and patients' fitness to undergo such a procedure, particularly given the high rate of surgical morbidity. Pelvic sidewall tumors have been a traditional contraindication for pelvic exenteration due to the difficulty in obtaining negative margins, but the use of laterally extended endopelvic resection and intra-operative radiation therapy allows for more radical resection of recurrent disease. We believe that these procedures to achieve R0 resection can expand the use of curative-intent surgery in recurrent gynecologic cancer, but require the surgical expertise of colleagues in orthopedic and vascular surgery and collaboration with plastic surgery for complex reconstruction and optimization of post-operative healing. Surgery of recurrent gynecologic cancer including pelvic exenteration, requires careful patient selection, pre-operative medical optimization and prehabilitation, and thorough counseling to optimize outcomes, both oncologic and peri-operative. We believe the creation of a well-developed team, including surgical teams and supportive care services, can lead to the best patient outcomes and improved professional satisfaction amongst providers.
