Laparoscopic pelvic exenteration and laterally extended endopelvic resection for postradiation recurrent cervical carcinoma: Technical feasibility and short-term oncologic outcome.
OBJECTIVE
Surgery is the only treatment for cervical cancer recurrence in a previously irradiated field. Pelvic exenteration (PE) and laterally extended endopelvic resection (LEER) are indicated for select patients; however, morbidity and mortality rates remain high, and new treatment modalities are required. Laparoscopy optimizes visualization and allows meticulous dissection while also reducing intraoperative blood loss and postoperative complications without worsening the outcomes. We aimed to clarify the feasibility and outcomes of laparoscopic PE and LEER for previously irradiated recurrent cervical cancer.
METHODS
We prospectively investigated the outcomes of laparoscopic PE and LEER in 28 patients with recurrent cervical carcinoma after radiotherapy.
RESULTS
Seventeen laparoscopic PEs for central recurrences and 11 laparoscopic LEERs for lateral recurrences were performed. The median operation time and blood loss were 454mins and 285 mL in the PE group, and 562mins and 325 mL in the LEER group, respectively, with no conversions to laparotomy. R0 resection was achieved in all patients in the PE group and 73% in the LEER group. The morbidity and mortality rates were 41% and 0% in PE group, and 55% and 0% in LEER group, respectively. The 2-year disease-free survival and overall survival were 68.9% and 76% in the PE group, and 27.3% and 29.6% in the LEER group, respectively.
CONCLUSION
Laparoscopic PE is feasible for previously irradiated central recurrent cervical cancer and has acceptable outcomes. Laparoscopic LEER is also feasible for lateral recurrence, but oncologic outcome may be modest in this limited preliminary study. Further studies using a larger sample size with a longer follow-up period is warranted to determine the indications for laparoscopic LEER.

With the development of existing surgical techniques, equipment and treatment concepts, more and more medical centers begin to carry out extensive resection for recurrent pelvic malignant tumors or those with multivisceral invasion. Exenteration may facilitate curative resection and improve the outcome of the patients. Therefore, pelvic exenteration has gradually become the standard of care for locally advanced pelvic malignancies. At present, pelvic exenteration leads to high intraoperative and postoperative complications and mortality, and therefore compromise the safety and long-term quality of life. Cumulating evidences suggest remnant cavity after exenteration might trigger the pathophysiological process and cause downstream complications which can be defined as empty pelvis syndrome. The literature related to empty pelvic syndrome was summarized, the possible cause of empty pelvic syndrome was analyzed. After the pelvic exenteration, the closed pelvic residual cavity formed continuous negative pressure with the gradual absorption of air in the cavity, bacterial propagation, and accumulation of fluid, which had an impact on the distribution of organs in the abdominal and pelvic cavity. At the same time, whether physical processes also play a role in the occurrence of empty pelvic syndrome remains to be explored. It is concluded that the diagnosis is mainly based on the patient's medical history, clinical manifestations and radiological findings, and the history of pelvic exenteration is the most important indicator in the diagnosis. In terms of prevention measures, we should identify the high-risk groups of the occurrence of empty pelvic syndrome, and then take accurate and individualized preventive measures. Various new biomaterials have more advantages in preventive pelvic cavity filling than traditional human tissue filling. Mesentery plays an important role in the morphology, peristalsis and arrangement of the small intestine. More attention should be paid to reducing the ectopic placement of the small intestine into the pelvic cavity by protecting the mesentery structure and restoring or rebuilding the mesentery morphology. In terms of treatment measures, there is still a lack of standard treatment pathway for empty pelvic syndrome.

Simultaneous laparoscopic nephroureterectomy and robot-assisted anterior pelvic exenteration with intracorporeal ileal conduit urinary diversion: step-by-step video-illustrated technique.
INTRODUCTION:
One of the most remarkable characteristics of urothelial carcinomas is multifocality. However, occurrence of synchronous bladder cancer and upper urinary tract urothelial cancer (UTUC) is exceptional. Minimally invasive approach for these synchronous tumors was just occasionally reported (1-4). The aim of this video article is to describe step-by-step the technique for simultaneous laparoscopic nephroureterectomy and robot-assisted anterior pelvic exenteration with intracorporeal ileal conduit urinary diversion (ICUD). Patients and methods: A 66-year-old female presented with synchronous BCG refractory non-muscle invasive bladder cancer and a right-side UTUC. She was a former smoker and had previously been submitted to multiple transurethral resections of bladder tumor, BCG and right distal ureterectomy with ureteral reimplant. We performed a simultaneous laparoscopic right nephroureterectomy and robot-assisted anterior pelvic exenteration with totally intracorporeal ICUD. Combination of robot-assisted and pure laparoscopic approaches was proposed focusing on optimization of total operative time (TOT).
RESULTS:
Surgery was uneventful. TOT was of 330 minutes. Operative time for nephroureterectomy, anterior pelvic exenteration and ICUD were 48, 135, 87 minutes, respectively. Estimated blood loss was 150mL. Postoperative course was unremarkable and patient was discharged after 7 days. Histopathological evaluation showed a pT1 high grade urothelial carcinoma plus carcinoma in situ both in proximal right ureter and bladder, with negative margins. Twelve lymph nodes were excised, all of them negative.
CONCLUSION:
In our preliminary experience, totally minimally invasive simultaneous nephroureterectomy and cystectomy with intracorporeal ICUD is feasible. Pure laparoscopic approach to upper urinary tract may be a useful tactic to reduce total operative time.

BACKGROUNDS
Total Pelvic Exenteration (TPE) is a radical operation for malignancies in which all of the organs inside the pelvic cavity, including the female reproductive organs, the lower urinary tract, and a part of the rectosigmoid are removed. In this study, we aimed to conduct a systematic review to assess the overall survival (OS) and disease-free survival (DFS) following TPE.
METHODS
This systematic review is composed of a comprehensive review of PubMed and Scopus databases with various related keywords to synthesis the overall survival and disease-free survival following TPE. The Synthesis Without Meta-analysis guideline was used to summarize the results.
RESULTS
We included the results of 39 primary studies and the results revealed that one-year OS of gynecological cancer in patients who have undergone TPE ranged from 50.0% to 72.0% and the 5-years OS ranged from 6.0% to 64.6%. The one-year survival rate of colorectal cancer patients was reported to be over 80% in almost all studies. The 3-year survival rate of patients varied from 25% to 75% and the lowest 5-year survival rate was 8% and the highest survival rate was 92%. To synthesis the disease-free survival rate in colorectal cancer, ten studies were included and one-year recurrence rate was 9.1% and the one-year DFS was reported as 61.0%. Three-year recurrence rate study was 20.4% and 3 and 5-year DFS ranged from 22.0% to 78.0%.
CONCLUSIONS
The results suggested that DFS in primary advanced cancers is higher than locally recurrence tumors. This review showed that patient overall survival and disease-free survival rates have increased over time, especially at high volume centers that are more experienced and possibly better equipped. Therefore, it can be suggested that the attitude towards PE as a palliative surgery can be turned into curative surgery.

OBJECTIVE
To examine the changes in exenterative surgery over three decades analysing oncological outcomes and whether changes in surgical approach have led to improved patient outcomes.
BACKGROUND
Advances in surgical technology, perioperative care and pattern of disease recurrence have coincided with an evolutionary change in exenterative surgery.
METHODS
A review of a prospectively maintained databases of pelvic exenteration surgery from 1988 to 2018 at two high volume specialised institutions. The total cohort was divided into three major time points (1988-2004, 2005-2010 and 2011 to 2018) to allow comparative analysis. Primary endpoints were overall survival in primary and recurrent disease at each time point. Secondary endpoints included anastomotic leak, blood transfusion, ileus, wound infection rates and evolution of case complexity. Data were analysed using R with a p < 0.05 considered significant.
RESULTS
Six hundred and seventy patients underwent exenterative surgery. In 2011-2018 there was an increase in resection of recurrent malignancy with a continuous increase in GI malignancies resected over each time period(p < 0.001,<0.01) and a reduction in gynaecological malignancy(p < 0.001). A significant increase in sacrectomy, pelvic sidewall resection and ileal conduit reconstruction was observed (p < 0.01,<0.001).In 2005-2010 patients had increased rates of ileus and anastomotic leak(p < 0.05). Patients undergoing resection for primary disease had improved overall survival at time points 1988-2004 and 2011-2018 compared to those with recurrent disease(p = 0.007,<0.001). Overall survival was significantly improved in patients with primary versus recurrent disease(p = 0.022).
CONCLUSION
There has been a significant improvement in survival in patients undergoing pelvic exenteration surgery from primary disease. Case complexity has increased without significant morbidity.

Review
BACKGROUND
Abdominoperineal resection (APR) and pelvic exenteration (PE) for the treatment of cancer require extensive pelvic resection with a high rate of postoperative complications. The objective of this work was to systematically review and meta-analyze the effects of vertical rectus abdominis myocutaneous flap (VRAMf) and mesh closure on perineal morbidity following APR and PE (mainly for anal and rectal cancers).
METHODS
We searched PubMed, Cochrane, and EMBASE for eligible studies as of the year 2000. After data extraction, a meta-analysis was performed to compare perineal wound morbidity. The studies were distributed as follows: Group A comparing primary closure (PC) and VRAMf, Group B comparing PC and mesh closure, and Group C comparing PC and VRAMf in PE.
RESULTS
Our systematic review yielded 18 eligible studies involving 2180 patients (1206 primary closures, 647 flap closures, 327 mesh closures). The meta-analysis of Groups A and B showed PC to be associated with an increase in the rate of total (Group A: OR 0.55, 95% CI 0.43-0.71; < 0.01/Group B: OR 0.54, CI 0.17-1.68; = 0.18) and major perineal wound complications (Group A: OR 0.49, 95% CI 0.35-0.68; < 0.001/Group B: OR 0.38, 95% CI 0.12-1.17; < 0.01). PC was associated with a decrease in total (OR 2.46, 95% CI 1.39-4.35; < 0.01) and major (OR 1.67, 95% CI 0.90-3.08; = 0.1) perineal complications in Group C.
CONCLUSION
Our results confirm the contribution of the VRAMf in reducing major complications in APR. Similarly, biological prostheses offer an interesting alternative in pelvic reconstruction. For PE, an adapted reconstruction must be proposed with specialized expertise.

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.

Laparoscopic posterior pelvic exenteration is safe and feasible for locally advanced primary rectal cancer in female patients: a comparative study from China PelvEx collaborative.
PURPOSE
Posterior pelvic exenteration (PPE) for locally advanced rectal cancer is a technical and challenging procedure. The safety and feasibility of laparoscopic PPE remain to be determined. This study aims to compare short-term and survival outcomes of laparoscopic PPE (LPPE) with open PPE (OPPE) in female patients.
METHOD
From January 2015 to December 2020, data from 105 female patients who underwent PPE at three institutions were retrospectively analyzed. The short-term and oncological outcomes between LPPE and OPPE were compared.
RESULTS
A total of 54 cases with LPPE and 51 cases with OPPE were enrolled. The operative time (240 vs. 295 min, p = 0.009), blood loss (100 vs. 300 ml, p < 0.001), surgical site infection (SSI) rate (20.4% vs. 58.8%, p = 0.003), urinary retention rate (3.7% vs. 17.6%, p = 0.020), and postoperative hospital stay (10 vs. 13 days, p = 0.009) were significantly lower in the LPPE group. The two groups showed no significant differences in the local recurrence rate (p = 0.296), 3-year overall survival (p = 0.129), or 3-year disease-free survival (p = 0.082). A higher CEA level (HR 1.02, p = 0.002), poor tumor differentiation (HR 3.05, p = 0.004), and (y)pT4b stage (HR 2.35, p = 0.035) were independent risk factors for disease-free survival.
CONCLUSION
LPPE is safe and feasible for locally advanced rectal cancers and shows lower operative time and blood loss, fewer SSI complications, and better preservation of bladder function without compromising oncological 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.

Pelvic exenteration combined with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for advanced primary or recurrent colorectal cancer with peritoneal metastases.
AIM
The aim was to report early outcomes of six patients who underwent combined pelvic exenteration (PE), cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for advanced or recurrent colorectal cancer with colorectal peritoneal metastases at a single centre. The literature contains limited data on the safety and oncological outcomes of patients who undergo this combined procedure.
METHODS
Six patients who underwent combined PE, CRS and HIPEC at Royal Prince Alfred Hospital, Sydney, between January 2017 and February 2020 were identified and included. Data were extracted from prospectively maintained databases.
RESULTS
Three patients underwent surgery for advanced primary rectal cancer, while two patients had recurrent sigmoid cancer and one had recurrent rectal cancer. All patients had synchronous peritoneal metastases. Two patients required total PE and two patients had a central (bladder-sparing) PE. The median peritoneal carcinomatosis index was 6 (range 3-12) and all patients underwent a complete cytoreduction. The median operating time was 702 min (range 485-900) and the median blood loss was 1650 ml (range 700-12,000). The median length of intensive care unit and hospital stay was 4.5 and 25 days, respectively. There was no inpatient, 30-day or 90-day mortality. Three patients (50%) experienced a major (Clavien-Dindo III/IV) complication. At a median follow-up of 11.5 months (range 2-18 months), two patients died with recurrent disease, one patient was alive with recurrence, while three patients remain alive and disease-free. Of the three patients who developed recurrent disease, one had isolated pelvic recurrence, one had pelvic and peritoneal recurrences and one had bone metastases.
CONCLUSION
Early results from this initial experience with simultaneous PE, CRS and HIPEC suggest that this combined procedure is safe and feasible; however, the long-term oncological and quality of life outcomes require further investigation.
