BACKGROUND: This study aimed to clarify the efficacy and safety of minimally invasive transabdominal surgery (MIS) with transperineal minimal invasive surgery (tpMIS) for sacrectomy in advanced primary and recurrent pelvic malignancies. METHODS: Using a prospectively collected database, we retrospectively analyzed the clinical, surgical, and pathological outcomes of MIS with tpMIS for sacrectomies. Surgery was performed between February 2019 and May 2023. The median follow-up period was 27 months (5-46 months). RESULTS: Fifteen consecutive patients were included in this analysis. The diagnoses were as follows: recurrent rectal cancer, n = 11 (73%); primary rectal cancer, n = 3 (20%); and recurrent ovarian cancer, n = 1 (7%). Seven patients (47%) underwent pelvic exenteration with sacrectomy, six patients (40%) underwent abdominoperineal resection (APR) with sacrectomy, and two patients (13%) underwent tumor resection with sacrectomy. The median intraoperative blood loss was 235 ml (range 45-1320 ml). The postoperative complications (Clavien-Dindo grade ≥ 3a) were graded as follows: 3a, n = 6 (40%); 3b, n = 1 (7%); and ≥ 4, n = 0 (0%). Pathological examinations demonstrated that R0 was achieved in 13 patients (87%). During the follow-up period, two patients (13%) developed local re-recurrence due to recurrent cancer. The remaining 13 patients (87%) had no local disease. Fourteen patients (93%) survived. CONCLUSIONS: Although the patient cohort in this study is heterogeneous, MIS with tpMIS was associated with a very small amount of blood loss, a low incidence of severe postoperative complications, and an acceptable R0 resection rate. Further studies are needed to clarify the long-term oncological feasibility.

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.

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.

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: 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.

BACKGROUND: Double barrelled uro-colostomy (DBUC) is an alternative to traditional ileal conduit (IC) and separate colostomy in patients requiring simultaneous urinary and faecal diversion for reconstruction in pelvic exenteration surgery (PES). METHODS: This cohort study evaluated short- and long-term morbidity and mortality associated with DBUC formation in 20 consecutive adult patients undergoing PES in an Australian Complex Pelvic Surgical Unit. Data were obtained from a prospective database. RESULTS: Mean age 59 years (range 27-76 years). PES was performed for malignant disease in 18 patients (curative intent in 17). Mean operative duration 11.8 h (range 7-17 h). Mean follow-up duration 29.1 months (range 2.6-90.1 months). Early DBUC-related complications occurred in four patients (20.0%): urinary tract infection (UTI)/urosepsis (n = 4) and early ureteric stenosis requiring intervention (n = 1). Late DBUC-related complications occurred in five patients (25.0%): recurrent UTI/urosepsis (n = 4), chronic kidney disease (n = 4), ureteric stenosis (n = 2) and parastomal hernia (n = 4). No mortality occurred secondary to a DBUC complication. CONCLUSION: DBUC is a safe reconstructive option with acceptable morbidity profile in patients requiring simultaneous urinary and faecal diversion.

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.

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.

AIM: Total pelvic exenteration (TPE) can achieve an R0 resection in locally advanced and recurrent rectal cancer (LARC and RRC) and remains the only curative option. The resultant high morbidity creates prolonged complex recoveries, rendering patients unfit for adjuvant chemotherapy. This study aims to evaluate the impact of this on overall survival (OS) and disease-free survival (DFS) as it has not been studied previously. METHOD: This is a retrospective single-centre study from 2017 to 2021 evaluating patients with LARC or RRC who underwent a curative TPE. Demographics, oncological history, perioperative data [using Clavien-Dindo (CD) scoring], disease recurrence and mortality were analysed using multivariate Cox regression to assess the impact of variables on DFS and OS. RESULTS: A total of 120 patients were included with a median follow-up of 3 years. 28% of patients received adjuvant chemotherapy, 27.5% had surgical follow-up and 44% missed systemic treatment. Missed treatment was predominantly due to prolonged recovery or poor performance status (59%). Patients who missed adjuvant chemotherapy experienced significantly higher CD scores (p = 0.0031), reintervention rates (p=0.0056) and further related surgeriesp (p = 0.0314). Missing adjuvant chemotherpy is a significant factor for poorer survival, with almost a three times higher mortality (p=0.0096, hazard ratio 2.7). R status was not a significant factor for OS following multivariate analysis (p = 0.336), indicating that another factor has an impact on survival within the first 2 years. CONCLUSIONS: In the initial 2 years after exenteration, an uncomplicated postoperative recovery allows for the delivery of adjuvant chemotherapy, prolonging survival. R0/R1 status was not the main prognostic factor. Longer follow-up and further multivariate analysis may influence decisions about aggressive R0 resection balanced against the patient being fit for chemotherapy postoperatively.

BACKGROUND: Pelvic exenterations and cytoreduction are individually morbid procedures with oncological validity. The combination of these simultaneously in patients with rectal cancers has not been evaluated. The present study aimed to assess the surgical and survival outcomes of the combined procedure. METHODS: Retrospective, single-centre analysis of consecutive patients that underwent pelvic exenterations and cytoreductions for advanced or recurrent rectal cancers with peritoneal metastasis between 2013 and 2022. The primary outcome measure for safety was major complications (≥Grade IIIA). The threshold for considering the procedure unsafe was set at 50% for the upper confidence limit of major morbidity. Overall and recurrence-free survival were also assessed. RESULTS: Thirty-nine patients underwent the combined procedure that included 24 total pelvic and 15 posterior pelvic exenterations. The median age of the cohort was 35 years, 18 (46.2%) had signet ring cell cancers, and eight patients (21%) had extraperitoneal disease as well. The median PCI was 4 and CC-0 was achieved in 38 patients (97.4%). Hyperthermic intraperitoneal chemotherapy was delivered in 15 patients, and four had placement of an intraperitoneal chemo port. Major complications were experienced by 7 patients (18%; 95% confidence interval: 7.5%-33.5%). Median recurrence-free and overall survivals were 9 and 17 months, respectively. CONCLUSION: Combined pelvic exenterations and cytoreductions are safe operations in terms of morbidity. Survival, however, remains poor for this group of patients despite aggressive surgery.

Ureteroenteric anastomotic strictures (UEAS) are typical complications after creating an ileal conduit for total pelvic exenteration (TPE) of rectal tumors. We report the ileal conduit for reconstruction in three patients, in the age-range of 47-73 years. Case 1 was when a left-sided UEAS had sufficient length of ureter for anastomosis, Case 2 was a right-sided UEAS with sufficient length of ureter for anastomosis, and Case 3 was a left-sided UEAS with insufficient length of ureter for anastomosis. There were no complications after operation and no recurrence of UEAS. It is important to learn the open surgical procedures for repair of a benign UEAS after TPE of rectal cancers. This has fewer complications and is safe in the long term.

BACKGROUND/AIM: Hyperchloremic metabolic acidosis after total pelvic exenteration (TPE) is relatively rare. Urinary diversion of the ileal conduit during TPE can result in increased urine reabsorption leading to hyperchloremic metabolic acidosis. We developed a new technique for the retrograde catheterization of a ureteral stent into an ileal conduit to treat hyperchloremic metabolic acidosis. CASE REPORT: A 70-year-old man underwent TPE for locally recurrent rectal cancer. Multiple episodes of complications, such as hyperchloremia and metabolic acidosis, occurred. Effective drainage of urine from the ileal conduit is crucial. With collaboration between an endoscopist and a radiologist, we developed a novel method for retrograde catheterization of the ureteral stent into an ileal conduit for hyperchloremic metabolic acidosis after TPE. The patient's condition quickly improved after the procedure. CONCLUSION: Our novel technique of retrograde catheterization of a ureteral stent into an ileal conduit for hyperchloremic metabolic acidosis could be adopted worldwide, as it is effective and safe.

Objective: To investigate the safety and efficacy of total pelvic exenteration (TPE) for treating late complications of radiation-induced pelvic injury. Methods: This was a descriptive case series study. The inclusion criteria were as follows: (1) confirmed radiation-induced pelvic injury after radiotherapy for pelvic malignancies; (2) late complications of radiation-induced pelvic injury, such as bleeding, perforation, fistula, and obstruction, involving multiple pelvic organs; (3) TPE recommended by a multidisciplinary team; (4) patient in good preoperative condition and considered fit enough to tolerate TPE; and (5) patient extremely willing to undergo the procedure and accept the associated risks. The exclusion criteria were as follows: (1) preoperative or intraoperative diagnosis of tumor recurrence or metastasis; (2) had only undergone diversion or bypass surgery after laparoscopic exploration; and (3) incomplete medical records. Clinical and follow-up data of patients who had undergone TPE for late complications of radiation-induced pelvic injury between March 2020 and September 2022 at the Sixth Affiliated Hospital of Sun Yat-sen University were analyzed. Perioperative recovery, postoperative complications, perioperative deaths, and quality of life 1 year postoperatively were recorded. Results: The study cohort comprised 14 women, nine of whom had recto-vagino-vesical fistulas, two vesicovaginal fistulas, one ileo-vesical fistula and rectal necrosis, one ileo-vesical and rectovaginal fistulas, and one rectal ulcer and bilateral ureteral stenosis. The mean duration of surgery was 592.1±167.6 minutes and the median blood loss 550 (100-6000) mL. Ten patients underwent intestinal reconstruction, and four the Hartmann procedure. Ten patients underwent urinary reconstruction using Bricker's procedure and 7 underwent pelvic floor reconstruction. The mean postoperative hospital stay was 23.6±14.9 days. Seven patients (7/14) had serious postoperative complications (Clavien-Dindo IIIa to IVb), including surgical site infections in eight, abdominopelvic abscesses in five, pulmonary infections in five, intestinal obstruction in four, and urinary leakage in two. Empty pelvis syndrome (EPS) was diagnosed in five patients, none of whom had undergone pelvic floor reconstruction. Five of the seven patients who had not undergone pelvic floor reconstruction developed EPS, compared with none of those who had undergone pelvic floor reconstruction. One patient with EPS underwent reoperation because of a pelvic abscess, pelvic hemorrhage, and intestinal obstruction. There were no perioperative deaths. During 18.9±10.1 months of follow-up, three patients died, two of renal failure, which was a preoperative comorbidity, and one of COVID-19. The remaining patients had gradual and significant relief of symptoms during follow-up. QLQ-C30 assessment of postoperative quality of life showed gradual improvement in all functional domains and general health at 1, 3, and 6 months postoperatively (all P<0.05). Conclusions: TPE is a feasible procedure for treating late complications of radiation-induced pelvic injury combined with complex pelvic fistulas. TPE is effective in alleviating symptoms and improving quality of life. However, the indications for this procedure should be strictly controlled and the surgery carried out only by experienced surgeons.

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.

BACKGROUND: The purpose of this study was to clarify the efficacy and safety of transanal minimally invasive surgery (TAMIS) for total pelvic exenteration (TPE) in advanced primary and recurrent pelvic malignancies. METHODS: Using a prospectively collected database, we retrospectively analyzed the clinical, surgical, and pathological outcomes of TAMIS for TPE. Surgery was performed between September 2019 and April 2023. The median follow-up period was 22 months (2-45 months). RESULTS: Fifteen consecutive patients were included in this analysis M:F = 14:1 and median (range) age was 63 (36-74). Their diagnoses were as follows: primary rectal cancer (n = 5; 33%), recurrent rectal cancer (n = 4; 27%), primary anorectal cancer (n = 5; 33%), and gastrointestinal stromal tumor (n = 1; 7%). Bladder-sparing TPE was selected for two patients (13%). In nine of 15 patients (60%) the anal sphincter could be successfully preserved, five patients (33%) required combined resection of the internal iliac vessels, and two (13%) required rectus muscle flap reconstruction. The median operative time was 723 min (561-1082), and the median intraoperative blood loss was 195 ml (30-1520). The Clavien-Dindo classifications of the postoperative complications were as follows: grade 0-2 (n = 11; 73%); 3a (n = 3; 20%); 3b (n = 1; 7%); and ≥ 4 (n = 0; 0%). No cases of conversion to laparotomy or mortality were observed. The pathological results demonstrated that R0 was achieved in 14 patients (93%). CONCLUSIONS: The short-term outcomes of this initial experience proved that this novel approach is feasible for TPE, with low blood loss, acceptable postoperative complications, and a satisfactory R0 resection rate.

BACKGROUND: Chronic fistulating pelvic sepsis is an uncommon complication of multimodal treatment of visceral pelvic tumours. Radical multi-visceral resection is reserved for patients with persistent, debilitating symptoms despite less invasive treatments and for which there is minimal published data. This study aimed to report the rates of morbidity and long-term sepsis control after pelvic exenteration for chronic fistulating pelvic sepsis. METHODS: This retrospective cohort study was conducted at a high-volume pelvic exenteration referral centre. Patients who underwent pelvic exenteration for chronic fistulating pelvic sepsis between September 1994 and January 2023 after previous treatment for pelvic malignancy were included. Data relating to postoperative morbidity, mortality and the rate of recurrent pelvic sepsis or fistulae were retrospectively collected. RESULTS: 19 patients who underwent radical resection for chronic fistulating pelvic sepsis after previous pelvic cancer treatment were included. 11 patients were male (58 %) and median age was 62 years (range 42-79). Previously treated rectal (8 patients, 42 %), prostate (5, 26 %) and cervical cancer (5, 26 %) were most common. 18 patients (95 %) had previously received high-dose pelvic radiotherapy, and 14 (74 %) had required surgical resection. Total pelvic exenteration was performed in 47 % of patients, total cystectomy in 68 % and major pubic bone resection in 37 %. There was no intraoperative or postoperative mortality. Major complication rate was 32 %. 12-month readmission rate was 42 %. At last follow up, 74 % had no signs or symptoms of persisting pelvic sepsis. CONCLUSIONS: Pelvic exenteration for refractory pelvic sepsis following treatment of malignancy is safe and effective in selected patients.

AIM: Anal cancer incidence and mortality rates are rising in the United Kingdom (UK). Surgery is an important treatment modality for persistent or recurrent disease. There is a paucity of data on outcomes for patients undergoing pelvic exenteration for anal squamous cell carcinoma (SCC) for persistent or recurrent disease. The aim of this study was to investigate the outcomes for patients who were treated with pelvic exenteration for anal SCC from two high-volume, high-complexity pelvic exenteration units in the UK. METHOD: A retrospective review of prospectively maintained databases from 2011 to 2020 was undertaken. Primary endpoints included R0 resection rates, overall and disease-free survival at 2 and 5 years. RESULTS: From 2011 to 2020, 35 patients with anal SCC were selected for exenteration. An R0 resection was achieved in 26 patients (77%). Of the remaining patients, seven patients had an R1 resection and one had a R2 resection. One further patient was excluded from additional analysis as the disease was inoperable at the time of laparotomy. With a median follow-up of 19.5 months (interquartile range 7.9-53.5 months), overall survival was 50% (17/34). Patients with an R1/2 resection had a significantly poorer overall survival [0.27 (0.09-0.76), p = 0.021] than those patients in whom R0 resection was achieved. Disease-free survival was 38.2% (13/34) and an R1/R2 resection was associated with a significantly reduced disease-free survival [0.12 (0.04-0.36), p < 0.001]. CONCLUSION: Complete R0 resection for recurrent or persistent anal SCC is possible in the majority of patients and improves overall and disease-free survival compared with R1/R2 resection.

A meta-analysis research was implemented to appraise the perineal wound complications (PWCs) after vertical rectus abdominis myocutaneous (VRAM) flap and mesh closure (MC) following abdominoperineal surgery (AS) and pelvic exenteration (PE) of anal and rectal cancers. Inclusive literature research till April 2023 was done and 2008 interconnected researches were revised. Of the 20 picked researches, enclosed 2972 AS and PE of anal and rectal cancers persons were in the utilized researchers' starting point, 1216 of them were utilizing VRAM flap, and 1756 were primary closure (PC). Odds ratio (OR) and 95% confidence intervals (CIs) were utilized to appraise the consequence of VRAM flap in treating AS and PE of anal and rectal cancers by the dichotomous approach and a fixed or random model. VRAM flap had significantly lower PWCs (OR, 0.64; 95% CI, 0.42-0.98, p < 0.001), and major PWCs (OR, 0.50; 95% CI, 0.32-0.80, p = 0.004) compared to PC in AS and PE of anal and rectal cancers persons. However, VRAM flap and PC had no significant difference in minor PWCs (OR, 1; 95% CI, 0.54-1.85, p = 1.00) in AS and PE of anal and rectal cancer persons. VRAM flap had significantly lower PWCs, and major PWCs, however, no significant difference was found in minor PWCs compared to PC in AS and PE of anal and rectal cancers persons. However, caution needs to be taken when interacting with its values since there was a low sample size of most of the chosen research found for the comparisons in the meta-analysis.
