OBJECTIVE
To evaluate pre-operative predictors of early (<30 days) severe complications (grade Dindo 3+) in patients with gynecological malignancy submitted to pelvic exenteration (PE).
METHODS
We retrospectively analyzed 129 patients submitted to surgery at Fondazione Policlinico Gemelli between 2010 and 2019. We included patients affected by primary or recurrent/persistent cervical, endometrial, or vulvar/vaginal cancers. Post-operative complications were graded according to the Dindo classification. Logistic regression was used to analyze potential predictors of complications.
RESULTS
We performed 63 anterior PE, 10 posterior PE, and 56 total PE. The incidence of early severe post-operative complications was 27.9% (n=36), and the early mortality rate was 2.3% (n=3). More frequent complications were related to the urinary diversion and intestinal surgery. In univariable analysis, hemoglobin ≤10 g/dL (odds ratio [OR]=4.2; 95% confidence interval [CI]=1.65-10.7; p=0.003), low albumin levels (OR=3.9; 95% CI=1.27-12.11; p=0.025), diabetes (OR=4.15; 95% CI=1.22-14.1; p=0.022), 2+ comorbidities at presentation (OR=5.18; 95% CI=1.49-17.93; p=0.012) were predictors of early severe complications. In multivariable analysis, only low hemoglobin and comorbidities at presentation were independent predictors of complications.
CONCLUSION
Pelvic exenteration is an aggressive surgery characterized by a high rate of post-operative complications. Pre-operative assessment of comorbidities and patient health status are crucial to better select the right candidate for this type of surgery.

Review
Total pelvic exenteration (TPE) is a highly invasive surgery associated with high rates of perioperative morbidity and mortality and is commonly performed for several types of locally advanced or recurrent pelvic cancers. It involves multivisceral resection, including the rectum, sigmoid colon, bladder, prostate, uterus, vagina, or ovaries, and urologists normally perform radical cystectomy or radical prostatectomy and urinary diversion in collaboration with colorectal surgeons and gynecologists. In the urological field, robot-assisted surgeries have been widely performed as one of the main minimally invasive procedures because of their superior perioperative or oncological outcomes compared to open or laparoscopic surgeries. In pelvic exenteration (PE) surgery, laparoscopic surgeries have shown superior rates of mortality, morbidity, and R0 resection compared to open surgeries. Robot-assisted TPE for the treatment of locally advanced rectal cancer was first reported in 2014, and reports of its safety and usefulness have gradually increased. Robot-assisted PE, in which multivisceral resection in a narrow pelvic space is easier, will eventually be a standard minimally invasive procedure, although evidence has been limited to date. This clinical practice review summarizes the indications for surgery, perioperative complications, and oncological outcomes of robot-assisted TPE and highlights the current status of robot-assisted TPE for patients with urological malignancies and its surgical technique, focusing on the manipulation of urological organs.

OBJECTIVE
To establish globally applicable benchmark outcomes for pelvic exenteration (PE) in patients with locally advanced primary (LARC) and recurrent rectal cancer (LRRC), using outcomes achieved at highly specialised centres.
BACKGROUND DATA
PE is established as the standard of care for selected patients with LARC and LRRC. There are currently no available benchmarks against which surgical performance in PE can be compared for audit and quality improvement.
METHODS
This international multicentre retrospective cohort study included patients undergoing PE for LARC or LRRC at 16 highly experienced centres between 2018 and 2023. Ten outcome benchmarks were established in a lower-risk subgroup. Benchmarks were defined by the 75th percentile of the results achieved at the individual centres.
RESULTS
763 patients underwent PE, of which 464 patients (61%) had LARC and 299 (39%) had LRRC. 544 patients (71%) who met predefined lower risk criteria formed the benchmark cohort. For LARC patients, the calculated benchmark threshold for major complication rate was ≤44%; comprehensive complication index (CCI): ≤30.2; 30-day mortality rate: 0%; 90-day mortality rate: ≤4.3%; R0 resection rate: ≥79%. For LRRC patients, the calculated benchmark threshold for major complication rate was ≤53%; CCI: ≤34.1; 30-day mortality rate: 0%; 90-day mortality rate: ≤6%; R0 resection rate: ≥77%.
CONCLUSIONS
The reported benchmarks for PE in patients with LARC and LRRC represent the best available care for this patient group globally and can be used for rigorous assessment of surgical quality and to facilitate quality improvement initiatives at international exenteration centres.

OBJECTIVE
To acknowledge that minimally invasive pelvic exenteration is a feasible alternative to open surgery and potentially identify prediction factors for patient outcome.
METHODS
The study was designed as a retrospective single team analysis of 12 consecutive cases, set between January 2008 and January 2022.
RESULTS
Six anterior and 6 total pelvic exenterations were performed. A 75% of cases were treated using a robotic approach. In 4 cases, an ileal conduit was used for urinary reconstruction. Mean operative time was 360±30.7 minutes. for anterior pelvic exenterations and 440±40.7 minutes. for total pelvic exenterations and mean blood loss was 350±35 mL. An R0 resection was performed in 9 cases (75%) and peri-operative morbidity was 16.6%, with no deaths recorded. Median disease-free survival was 12 months (10-14) and overall survival (OS) was 20 months (1-127). In terms of OS, 50% of patients were still alive 24 months after surgery. Taking into consideration the follow up period,16.6% of females under 50 or above 70 years old did not reach the cut off and 4 out of 6 patients that failed to reach it were diagnosed with distant metastases or local recurrence (p=0.169).
CONCLUSION
Our experience is very much consistent with literature in regard to primary site of cancer, post-operative complications, R0 resection and survival rates. On the other hand, minimally invasive approach and urinary reconstruction type were in contrast with cited publications. Minimally invasive pelvic exenteration is indeed a safe and feasible procedure, providing patients selection is appropriately performed.

BACKGROUND
Pelvic exenteration (PE) is an extensive surgery that is indicated in cases of recurrent advanced gynecological cancer with curative and sometimes palliative intent. The procedure is associated with both high morbidity and mortality and as such is considered a highly specialist procedure. The aim of the study was to analyze surgical outcomes in women who underwent PE for advanced gynecological malignancy in a tertiary cancer referral center over 11 years.
METHODS
This is an observational retrospective single-center study. There were 17 patients included who underwent PE in Hull Royal Infirmary Hospital (Hull, UK) between 2010 and 2021. The main outcome measures were the perioperative complications, overall survival (OS), and recurrence free survival (RFS). Cumulative survival rates were reported at 1, 3 and 5 years. Univariate Cox regression analysis was undertaken to analyze factors that are prognostic for OS and RFS. Hazard Ratios (HR) with 95% confidence intervals (95% CI) were computed from the results of the Cox regression analyses. Kaplan-Meier survival curves were generated to visually display estimates of OS and RFS over the follow-up period.
RESULTS
The median age at the time of surgery was 63.0 (IQR: 48.0-71.0). All patients received surgery with curative intent and complete tumor resection (R0) was achieved in 94.1% of cases. An overall 5-year survival was achieved in 63.7% of patients. Mean overall survival (OS) was 8.4 years (95% CI: 7.78-9.02). The RFS was 5.0 years (95% CI: 4.13-5.87). Both OS and RFS were significantly negatively affected by the hospital stay (P=0.020 and P=0.035, respectively), but not by the type of surgery (P=0.263 and P=0.826, respectively).
CONCLUSIONS
The results of the study demonstrated stable and comparable outcomes in patients undergoing pelvic exenteration.

BACKGROUND
Total pelvic exenteration (TPE) in men is a surgical procedure to treat genitourinary and colorectal malignancies. Despite improvement in multimodal strategies and technology, mortality is still high and literature is limited about perioperative outcomes comparison to other radical procedures.
METHODS
We analyzed National Surgical Quality Improvement Program (NSQIP) baseline database of all male patients undergoing cystectomy, low anterior resection/abdominoperineal resection (LAR/APR) or TPE from January 1, 2005 to December 31, 2016. Postoperative complications within 30 days after surgery were measured including: Wound infection, septic complications, deep vein thrombosis, cardiovascular events, and return to the operating room or mortality, etc. Differences between groups were analyzed using analysis of variance (ANOVA) tests.
RESULTS
A total of 7,375 patients underwent radical cystectomy, 49,762 underwent LAR/APR and 792 underwent TPE. Cystectomy patients were on average older compared to TPE or LAR/APR patients (P<0.001). In univariable and multivariable analysis, patients undergoing TPE had greater infectious and septic complications compared to cystectomy (odds ratio =1.09; 95% confidence interval (CI): 1.06-1.12) and LAR/APR (odds ratio =1.08; 95% CI: 1.05-1.11). Moreover, TPE had a slightly higher mortality within the 30-day postoperatively than those who underwent LAR/APR (odds ratio =1.01; 95% CI: 1.00-1.02) and cystectomy (odds ratio =1.01; 95% CI: 1.00-1.01).
CONCLUSIONS
Men undergoing TPE had greater rates of infections and postoperative complications compared to those undergoing radical cystectomy and LAR/APR. From a clinical standpoint, TPE has high morbidity that could provide opportunity for quality improvement projects with the goal of mitigating high complication rates.

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.

Review
Vulvo-vaginal melanomas are one of the rarest gynecological oncology diseases with a poor survival compared with other malignancies. The 5-year survival varies from 13% to 32.3%. Vulvo-vaginal melanomas involving the upper 2/3rds of the vagina are usually treated with total pelvic exenteration (TPE). TPE surgery carries a 50% risk of major complications and also morbidity associated with double stomas. Central pelvic compartment resection is a novel organ-sparing surgical approach entailing radical total laparoscopic hysterectomy, bilateral salpingo-oophrectomy, laparoscopic vaginectomy and vulvectomy to reduce morbidity compared with TPE. Permanent suprapubic catheters are used if there is urethral involvement but require quality of life studies to assess their long-term outcomes.

BACKGROUND
Flap reconstruction is often required after pelvic tumor resection to reduce wound complications. The use of perforator flaps has been shown to reduce donor site morbidity. The purpose of this study was to evaluate the outcomes of pedicled deep inferior epigastric perforator (pDIEP) flap reconstruction.
METHODS
This was a retrospective multicenter study of patients who underwent immediate pDIEP flap reconstruction for a pelvic or perineal defect after tumor resection between November 2012 and June 2022. The primary outcome was abdominal donor site morbidity, and the secondary outcome was perineal morbidity.
RESULTS
Thirty-four patients (median age, 57.5 years) who underwent pelvic exenteration (n = 31), extralevator abdominoperineal excision (n = 2), or extended vaginal hysterectomy (n = 1) were included. The most common indications were recurrent cervical (n = 19) and anal (n = 4) squamous cell carcinoma. Twenty-nine patients (85%) had a history of radiotherapy. Only one patient (3%) had major (Clavien-Dindo ≥ III) donor site complications (surgical site infection due to tumor recurrence). Eleven patients (32%) had at least one major recipient site complication (surgical site infection [n = 1], total [n = 2] or partial [n = 1] flap loss, perineal dehiscence [n = 2], hematoma [n = 1], fistula [n = 5]). No incisional or perineal hernias were observed during follow-up. Ninety-day survival was 100%.
CONCLUSION
Pedicled DIEP flap reconstructions performed by experienced surgical teams had good outcomes for perineal or vaginal reconstruction, with low abdominal morbidity, in patients with advanced pelvic malignancies who had undergone median laparotomy. The risks and benefits of this procedure should be carefully evaluated preoperatively using clinical and imaging data.
