Review
AIM
Empty pelvis syndrome is a major contributor to morbidity following pelvic exenteration. Several techniques for filling the pelvis have been proposed; however, there is no consensus on the best approach. We evaluated and compared the complications associated with each reconstruction technique with the aim of determining which is associated with the lowest incidence of complications related to the empty pelvis.
METHOD
The systematic review protocol was prospectively registered with PROSPERO (CRD42021239307). PRISMA-P guidelines were used to present the literature. PubMed and MEDLINE were systematically searched up to 1 February 2021. A dataset containing predetermined primary and secondary outcomes was extracted.
RESULTS
Eighteen studies fulfilled our criteria; these included 375 patients with mainly rectal and gynaecological cancer. Only three studies had a follow-up greater than 2 years. Six surgical interventions were identified. Mesh reconstruction and breast prosthesis were associated with low rates of small bowel obstruction (SBO), entero-cutaneous fistulas and perineal hernia. Findings for myocutaneous flaps were similar; however, they were associated with high rates of perineal wound complications. Omentoplasty was found to have a high perineal wound infection rate (40%). Obstetric balloons were found to have the highest rates of perineal wound dehiscence and SBO. Silicone expanders effectively kept small bowel out of the pelvis, although rates of pelvic collections remained high (20%).
CONCLUSION
The morbidity associated with an empty pelvis remains considerable. Given the low quality of the evidence with small patient numbers, strong conclusions in favour of a certain technique and comparison of these interventions remains challenging.

Meta-Analysis
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
Pelvic exenteration remains a viable and effective treatment option for the management of locally advanced or recurrent pelvic malignancy. The aim of this study was to present an early experience of robotic multivisceral resection of pelvic malignancy, and to compare this experience with similar series through a systematic review of the literature.
METHODS
A retrospective study was performed on patients who had robotic-assisted multi-visceral resection for pelvic malignancy at a single Colorectal Surgical unit based between two tertiary academic hospitals. Primary outcomes observed included operation type, operation time, perioperative complications, and hospital length of stay. Secondary outcomes included R0 resection status, lymph node harvest, and rate of recurrence at clinical follow-up.
RESULTS
Eight cases of robotic multivisceral resection were performed for primary locally advanced pelvic malignancy involving a rectal resection as part of their operative management. The median age of patients undergoing resection was 56 years (range 29-83 years). The male:female ratio was 6:2. The mean total operating time was 8.3 h (range 6-10 h). Perioperative blood transfusion requirements were minimal. Mean hospital length of stay was 15 days (range 7-26 days). No patients experienced any serious postoperative morbidity or mortality. All patients had clear margins on histological assessment and no patients have recurrence at 12-month follow-up.
CONCLUSIONS
Robotic multivisceral resection for malignant disease of the pelvis is a safe and feasible minimally invasive approach in highly selected cases.

Review
INTRODUCTION
Pelvic exenteration (PE) is now the standard of care for locally advanced (LARC) and locally recurrent (LRRC) rectal cancer. Reports of the significant short-term morbidity and survival advantage conferred by R0 resection are well established. However, longer-term outcomes are rarely addressed. This systematic review focuses on long-term oncosurgical and quality of life (QoL) outcomes following PE for rectal cancer.
METHODS
A systematic review of the PubMed, Cochrane Library, MEDLINE and Embase databases was conducted, in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Studies were included if they reported long-term outcomes following PE for LARC or LRRC. Studies with fewer than 20 patients were excluded.
FINDINGS
A total of 25 papers reported outcomes for 5,489 patients. Of these, 4,744 underwent PE for LARC (57.5%) or LRRC (42.5%). R0 resection rates ranged from 23.2% to 98.4% and from 14.9% to 77.8% respectively. The overall morbidity rates were 17.8-87.0%. The median survival ranged from 12.5 to 140.0 months. None of these studies reported functional outcomes and only four studies reported QoL outcomes. Numerous different metrics and timepoints were utilised, with QoL scores frequently returning to baseline by 12 months.
CONCLUSIONS
This review demonstrates that PE is safe, with a good prospect of R0 resection and acceptable mortality rates in selected patients. Morbidity rates remain high, highlighting the importance of shared decision making with patients. Longer-term oncological outcomes as well as QoL and functional outcomes need to be addressed in future studies. Development of a core outcomes set would facilitate better reporting in this complex and challenging patient group.

Review
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.

Review
The standard treatment approach in locally advanced cervical cancer (LACC) is exclusive concurrent chemoradiation therapy (RTCT). The risk of local residual disease after six months from RTCT is about 20-30%. It is directly related to relapse risk and poor survival, such as in patients with recurrent cervical cancer. This systematic review aims to describe studies investigating salvage surgery's role in persistent/recurrent disease in LACC patients who underwent definitive RTCT. Studies were eligible for inclusion when patients had LACC with radiologically suspected or histologically confirmed residual disease after definitive RTCT, diagnosed with post-treatment radiological workup or biopsy. Information on complications after salvage surgery and survival outcomes had to be reported. The methodological quality of the articles was independently assessed by two researchers with the Newcastle-Ottawa scale. Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we systematically searched the PubMed, Scopus, Cochrane, Medline, and Medscape databases in May 2022. We applied no language or geographical restrictions but considered only English studies. We included studies containing data about postoperative complications and survival outcomes. Eleven studies fulfilled the inclusion criteria and all were retrospective observational studies. A total of 601 patients were analyzed concerning the salvage surgery in LACC patients for persistent/recurrent disease after RTCT treatment. Overall, 369 (61.4%) and 232 (38.6%) patients underwent a salvage hysterectomy (extrafascial or radical) and pelvic exenteration (anterior, posterior, or total), respectively. Four hundred and thirty-nine (73%) patients had histologically confirmed the residual disease in the salvage surgical specimen, and 109 patients had positive margins (overall range 0-43% of the patients). The risk of severe (grade ≥ 3) postoperative complications after salvage surgery is 29.8% (range 5-57.5%). After a median follow-up of 38 months, the overall RR was about 32% with an overall death rate of 40% after hysterectomy or pelvic exenteration with or without lymphadenectomy. There is heterogeneity between the studies both in their design and results, therefore the effect of salvage surgery on survival and recurrence cannot be adequately estimated. Future homogeneous studies with an appropriately selected population are needed to analyze the safety and efficacy of salvage hysterectomy or pelvic exenteration in patients with residual tumors after definitive RTCT.

BACKGROUND
The treatment of locally advanced or recurrent anorectal cancer requires radical surgery such as extralevator abdominoperineal resection and pelvic exenteration. Larger defects require flap reconstruction. The authors evaluated outcomes of different perineal reconstruction techniques.
METHODS
A systematic search was performed in the PubMed, Embase, and Cochrane databases. Studies reporting outcomes on perineal flap reconstruction in patients with anal or colorectal cancer were included. Data on patient characteristics, surgical details, perineal and donor-site complications, revision surgery, mortality, and quality of life were extracted. Articles were assessed using the Group Reading Assessment and Diagnostic Evaluation approach.
RESULTS
The authors included 58 mainly observational studies comprising 1988 patients. Seventy-three percent of patients had rectal cancer. The majority of 910 abdominoperineal resection patients underwent reconstruction with rectus abdominis flaps (91 percent). Dehiscence (15 to 32 percent) and wound infection (8 to 16 percent) were the most common complications. Partial flap necrosis occurred in 2 to 4 percent and flap loss occurred in 0 to 2 percent. Perineal herniation was seen in 6 percent after gluteal flap reconstruction and in 0 to 1 percent after other types of reconstruction. Donor-site complications were substantial but were reported inconsistently.
CONCLUSIONS
Clinical outcome data on perineal reconstruction after exenterative surgery are mostly of very low quality. Perineal reconstruction after pelvic exenteration is complex and requires a patient-tailored approach. Primary defect size, reconstruction aims, donor-site availability, and long-term morbidity should be taken into account. This review describes the clinical outcomes of four flap reconstruction techniques. Shared clinical decision-making on perineal reconstruction should be based on these present comprehensive data.

BACKGROUND
Shared decision-making in pelvic exenteration is a complex and detailed process, which must balance clinical, oncological and patient-reported outcomes (PROs), whilst addressing and valuing the patient priorities. Communicating patient-centred information on quality of life (QoL) and functional outcomes is an essential component of this. The aim of this systematic review was to understand the impact of pelvic exenteration on QoL PROs over a longitudinal period and to develop QoL trajectories to support decision-making in this context.
METHODS
MEDLINE, Embase and Web of Science databases were searched between 1 January 2000 and 20 December 2021 Studies reporting on PROs, including QoL, in adults undergoing pelvic exenteration were included. Risk of bias was assessed using the ROBINS-I assessment tool. Data from studies reporting QoL using the same outcome measure at the same candidate timepoint were extracted and synthesised to develop a longitudinal QoL trajectory.
RESULTS
Fourteen studies consisting of 1370 patients were included in this review. QoL trajectories were constructed in the domains of physical function, psychological function, role function, sexual function, body image and general and specific symptoms. Decision-making was only assessed by one study, with satisfaction with decision-making reported to be high. There is an initial decline in QoL scores in the domains of physical function, role function, sexual function, body image and general health and symptoms deteriorating during the first 3-6 months post-operatively. Psychological function is the only QoL domain that remains stable throughout the post-operative period.
CONCLUSION
Mapping QoL trajectories provides a visual representation of post-operative progress, highlighting the enduring impact of pelvic exenteration on patients and can be used to inform pre-operative shared decision-making.

Review
AIM
Locally advanced and recurrent colorectal cancer can require extended surgery, including reconstruction of the vagina. This complex surgery carries high morbidity. The aim of this study was to analyse the impact on female sexual functioning of pelvic exenteration (PE), with or without vaginal flap reconstruction, for locally advanced or recurrent colorectal cancer.
METHOD
The protocol with search strategies for PubMed (Medline), EMBASE and the Cochrane Library was registered in PROSPERO. Studies published from 2000 onwards meeting the inclusion criteria were considered. Study selection (Rayyan), data extraction, rating of evidence (GRADE) and risk of bias (ROBINS-I) were conducted independently by two reviewers.
RESULTS
Six of 2479 identified records were included: four retrospective and two cross-sectional studies. Of all 860 patients included, PE was performed in 314 patients. Seven hundred and thirty-two had rectal cancer (85.1%), 80 nonadvanced rectal cancer (10.9%), 393 locally advanced rectal cancer (53.7%) and 217 locally recurrent rectal cancer (29.6%); for 45 patients the type of rectal cancer remained unspecified (6.1%). Three studies reported on both preoperative and postoperative female sexual activity. Of the 153 women who were sexually active preoperatively, 64 (41.8%) reported postoperative sexual activity. The VRAM flap was used the most frequently and resulted in a sexual activity ratio of 18% postoperatively. Four studies, using six different validated questionnaires, reported mostly lowered sexual functioning postoperatively.
CONCLUSION
Most studies showed that PE can result in severe sexual dysfunction despite reconstruction. Future prospective studies can fill the current knowledge gap by assessing long-term sexual outcomes in women.

Meta-Analysis
BACKGROUND
To mitigate pelvic wound issues following perineal excision of rectal or anal cancer, a number of techniques have been suggested as an alternative to primary closure. These methods include the use of a biological/dual mesh, omentoplasty, muscle flap, and/or pelvic peritoneum closure. The aim of this network analysis was to compare all the available surgical techniques used in the attempt to mitigate issues associated with an empty pelvis.
METHODS
An electronic systematic search using MEDLINE databases (PubMed), EMBASE, and Web of Science was performed (Last date of research was March 15th, 2023). Studies comparing at least two of the aforementioned surgical techniques for perineal wound reconstruction during abdominoperineal resection, pelvic exenteration, or extra levator abdominoperineal excision were included. The incidence of primary healing, complication, and/or reintervention for perineal wound were evaluated. In addition, the overall incidence of perineal hernia was assessed.
RESULTS
Forty-five observational studies and five randomized controlled trials were eligible for inclusion reporting on 146,398 patients. All the surgical techniques had a comparable risk ratio (RR) in terms of primary outcomes. The pooled network analysis showed a lower RR for perineal wound infection when comparing primary closure (RR 0.53; Crl 0.33, 0.89) to muscle flap. The perineal wound dehiscence RR was lower when comparing both omentoplasty (RR 0.59; Crl 0.38, 0.95) and primary closure (RR 0.58; Crl 0.46, 0.77) to muscle flap.
CONCLUSIONS
Surgical options for perineal wound closure have evolved significantly over the last few decades. There remains no clear consensus on the "best" option, and tailoring to the individual remains a critical factor.
