RESUMO
Locally advanced or recurrent prostate cancer which invades adjacent pelvic organs, bone or other soft tissue structures is a rare situation. This study aimed to report the outcomes of ten consecutive patients who underwent total pelvic exenteration for prostate cancer at a high-volume specialist centre. Two patients had locally advanced primary tumours, while eight had locally recurrent prostate cancer. Median operating time, blood loss, ICU stay, and hospital stay was 12.2 h (range 9.6-13.8), 2500 ml (500-3000), 4.5 days (2-7) and 36 days (21-78), respectively. There was no inpatient, 30-day, or 90-day mortality. Six patients developed a Clavien-Dindo III complication. R0 resection was achieved in eight patients. Median follow up was 16 months (range 2-77). At last follow up, five patients were alive without disease. These findings suggest that pelvic exenteration for locally advanced and recurrent prostate cancer is safe and represents a potentially curative treatment option for highly selected patients.

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: Extended radical resection is often the only chance of cure for locally recurrent rectal cancer. Recurrence in the posterior compartment often necessitates en bloc sacrectomy as part of pelvic exenteration to obtain clear resection margins and provide survival benefit. OBJECTIVE: To compare oncological outcomes, morbidity, and quality-of-life outcomes following pelvic exenteration with and without en bloc sacrectomy for recurrent rectal cancer. DESIGN: Comparative cohort study with retrospective analysis of prospectively collected data. SETTING: This study was conducted at a high-volume pelvic exenteration center. PATIENTS: Patients who underwent pelvic exenteration for locally recurrent rectal cancer between 1994 and 2022. MAIN OUTCOME MEASURES: Overall survival, postoperative morbidity, R0 resection margin, and quality-of-life outcomes. RESULTS: Of 965 patients, 305 (31.6%) underwent pelvic exenteration for locally recurrent rectal cancer. Among these patients, 64.3% were men and the median age was 62 years (range, 29-86). One hundred eighty-five patients (60.7%) underwent en bloc sacrectomy, 65 (35.1%) underwent high transection, and 119 (64.3%) had sacrectomy below S2. R0 resection was achieved in 80% of patients with sacrectomy and 72.5% of patients without sacrectomy. Sacrectomy patients experienced more postoperative complications without increased mortality. The median overall survival was 52 months; median survival was 47 months with sacrectomy and 73 months without ( p = 0.059). Quality-of-life scores were not significantly different across physical component ( p = 0.346), mental component ( p = 0.787), or Functional Assessment of Cancer Therapy-Colorectal ( p = 0.679) scores at 24-month follow-up. LIMITATIONS: The generalizability of these findings may be limited outside of subspecialist exenteration units. Selection bias exists in a retrospective analysis. CONCLUSIONS: Patients undergoing pelvic exenteration with and without en bloc sacrectomy for locally recurrent rectal cancer experience similar rates of R0 resection, survival, and quality-of-life outcomes. As R0 remains the most important predictor of survival, the requirement of sacral resection should prompt referral to a subspecialist center that performs sacrectomy routinely. See Video Abstract . RESULTADOS DESPUS DE LA EXENTERACIN PLVICA PARA EL CNCER DE RECTO CON RECURRENCIA LOCAL, CON Y SIN SACRECTOMA EN BLOQUE: ANTECEDENTES:La resección radical ampliada es generalmente la única posibilidad de curación para el cáncer de recto con recurrencia local. La recurrencia en el compartimento posterior generalmente requiere sacrectomía en bloque como parte de la exenteración pélvica para obtener márgenes de resección claros y proporcionar un beneficio de supervivencia.OBJETIVO:Comparar los resultados oncológicos, de morbilidad y de calidad de vida después de la exenteración pélvica con y sin sacrectomía en bloque para el cáncer de recto recurrente.DISEÑO:Estudio de cohorte comparativo con análisis retrospectivo de datos recopilados prospectivamente.AMBIENTE AJUSTE:Estudio realizado en un centro de exenteración pélvica de alto volumen.PACIENTES:Aquellos sometidos a exenteración pélvica por cáncer de recto con recurrencia local entre 1994 y 2022.PRINCIPALES MEDIDAS DE RESULTADO:Supervivencia general, morbilidad posoperatoria, margen de resección R0 y resultados de calidad de vida.RESULTADOS:305 (31,6%) de 965 pacientes se sometieron a exenteración pélvica por cáncer de recto con recurrencia local. El 64,3% de los pacientes eran hombres con una mediana de edad de 62 años (rango 29-86). 185 pacientes (60,7%) fueron sometidos a sacrectomía en bloque, 65 (35,1%) fueron sometidos a transección alta, 119 (64,3%) tuvieron sacrectomía por debajo de S2. La resección R0 se logró en el 80% de los pacientes con sacrectomía y en el 72,5% sin ella. Los pacientes de sacrectomía experimentaron más complicaciones postoperatorias sin aumento de la mortalidad. La mediana de supervivencia global fue de 52 meses, 47 meses con sacrectomía y 73 meses sin sacrectomía ( p = 0,059). Las puntuaciones de calidad de vida no fueron significativamente diferentes entre las puntuaciones del componente físico ( p = 0,346), componente mental ( p = 0,787) o la evaluación funcional de la terapia contra el cáncer - colorrectal ( p = 0,679) a los 24 meses de seguimiento.LIMITACIONES:La generalización de estos hallazgos puede estar limitada fuera de las unidades de exenteración de subespecialistas. Existe un sesgo de selección en un análisis retrospectivo.CONCLUSIONES:Los pacientes sometidos a exenteración pélvica con y sin sacrectomía en bloque por cáncer de recto con recurrencia local experimentan tasas similares de resección R0, supervivencia y resultados de calidad de vida. Como R0 sigue siendo el predictor más importante de supervivencia, la necesidad de resección sacra debe provocar la derivación a un centro subespecialista que realice sacrectomía de forma rutinaria.

According to Hohenberger's original description, complete mesocolic excision for colon cancer involves precise dissection of the avascular embryonic plane between the parietal retroperitoneum and visceral peritoneum of the mesocolon. This ensures mesocolic integrity, access to high ligation of the supplying vessels at their origin and an associated extended lymphadenectomy. Results from centres which have adopted this approach routinely have demonstrated that oncological outcomes can be improved by the rigorous implementation of established principles of cancer surgery. Meticulous anatomical dissection along embryonic planes is a well-established principle of precision cancer surgery used routinely by the specialist colorectal surgeon. Therefore, the real question concerns the need for true central vascular ligation and associated extended (D3) lymphadenectomy or otherwise, particularly along the superior mesenteric vessels when performing a right colectomy. Whether this approach results in improved overall or disease-free survival remains unclear and its role remains controversial particularly given the potential for significant morbidity associated with a more extensive central vascular dissection. Current literature is limited by considerable bias, as well as inconsistent and variable terminology, and the results of established randomized trials are awaited. As a result of the current state of equipoise, various national guidelines have disparate recommendations as to when complete mesocolic excision should be performed if at all. This article aims to review the rationale for and technical aspects of complete mesocolic excision, summarize available short and long term outcome data and address current controversies.

BACKGROUND: Information on the course of quality of life after surgery for advanced cancers within the pelvis is important to guide patient decision-making; however, the current evidence is limited. OBJECTIVE: To identify quality-of-life trajectory classes and their predictors after pelvic exenteration. DESIGN: Prospective cohort study. SETTINGS: Highly specialized quaternary pelvic exenteration referral center. PATIENTS: Patients undergoing pelvic exenteration due to advanced/recurrent cancers within the pelvis between July 2008 and July 2022. MAIN OUTCOME MEASURES: Quality-of-life data included the 36-item Short-Form Survey (physical and mental component scores) and the Functional Assessment of Cancer Therapy-Colorectal instruments, which were collected at 11 distinct points from baseline to 5 years postoperatively. Predictors included patient characteristics and surgical outcomes. Latent class analysis was used to identify the likelihood of a better quality-of-life class, and logistic regression models were used to identify predictors of the identified classes. RESULTS: The study included 565 participants. Two distinct quality-of-life trajectory classes were identified for the Physical Component Score (class 1: high stable and class 2: high decreasing). Three distinct classes were identified for the Mental Component Score (class 1: high increasing, class 2: moderate stable, and class 3: moderate decreasing) and for Functional Assessment of Cancer Therapy-Colorectal total score (class 1: high increasing, class 2: high decreasing, and class 3: low decreasing). Across the 3 quality-of-life domains, overall survival probabilities were also higher in class 1 ( p < 0.0001). Age, repeat exenteration, neoadjuvant therapy, surgical margin, length of operation, and hospital stay were significant predictors of quality-of-life classes. LIMITATIONS: This study was conducted at a single highly specialized quaternary pelvic exenteration referral center, and findings may not apply to other centers. CONCLUSIONS: This study demonstrates that quality of life after pelvic exenteration diverges into distinct trajectories, with most patients reporting an optimal course. See Video Abstract . TRAYECTORIAS EN LA CALIDAD DE VIDA DESPUS DE EXENTERACIN PLVICA ANLISIS DE CRECIMIENTO DE CLASES LATENTES: ANTECEDENTES:La información sobre la evolución en la calidad de vida después de cirugía en cánceres avanzados situados en la pelvis es importante para guiar la toma de decisiones sobre el paciente; sin embargo, la evidencia actual es muy limitada.OBJETIVO:Identificar las clases de trayectorias en la calidad de vida y sus factores pronóstico después de la exenteración pélvica.DISEÑO:Estudio de cohortes prospectivo.AJUSTES:Centro de referencia altamente especializado en la exenteración pélvica cuaternaria.PACIENTES:Todos aquellos sometidos a exenteración pélvica por cáncer avanzados/recurrentes situados en la pelvis entre Julio de 2008 y Julio de 2022.PRINCIPALES MEDIDAS DE RESULTADO:Los datos sobre la calidad de vida incluyeron el Cuestionario de Salud SF-36 (puntuaciones de componentes físicos y mentales) y la evaluación funcional entre la terapia del cáncer/-herramientas colorrectales, recopilados en 11 puntos distintos desde el diagnóstico hasta los 5 años después de la operación.Los predictores incluyeron las características de los pacientes y los resultados quirúrgicos. Se utilizó el análisis de clases latentes para identificar la probabilidad de una mejor calidad de vida y se utilizaron modelos de regresión logística para identificar predictores de las clases identificadas.RESULTADOS:El estudio incluyó a 565 participantes. Se identificaron dos clases distintas de trayectorias de calidad de vida para la puntuación del componente físico (clase 1: alta estable y clase 2: alta decreciente), se identificaron tres clases distintas para la puntuación del componente mental (clase 1: alta creciente; clase 2: moderadamente estable; y clase 3: moderada disminución) y para la evaluación funcional de la terapia contra el cáncer-puntuación total colorrectal (clase 1: aumento alto; clase 2: disminución alta; y clase 3: disminución baja). En los tres dominios de calidad de vida, las probabilidades de supervivencia general también fueron mayores en las clases 1 (p <0,0001). La edad, las exenteraciones pélvicas repetidas, la terapia neoadyuvante, el margen quirúrgico, la duración de la operación y la estadía hospitalaria fueron predictores significativos en las clases de calidad de vida.LIMITACIONES:El presente estudio fué realizado en un único centro de referencia altamente especializado en exenteración pélvica cuaternaria y es posible que los hallazgos no se apliquen a otros centros.CONCLUSIONES:Demostramos con nuestro estudio que la calidad de vida después de la exenteración pélvica diverge en trayectorias distintas, y que la mayoría de los pacientes nos reportaron de una évolución óptima.

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.

OBJECTIVE: To assess the effect of changing our sacrectomy approach from prone to anterior on surgical and oncological outcomes. BACKGROUND: In patients with advanced pelvic malignancy involving the sacrum, pelvic exenteration (PE) with en-bloc sacrectomy is the only potential curative option but morbidity is high. Over time sacrectomy techniques have evolved from prone sacrectomy (PS) to abdominolithotomy sacrectomy (ALS, ≤S3) and high anterior cortical sacrectomy (HACS, >S3) to optimize surgical outcomes. METHODS: A retrospective, single institution analysis of prospectively collected data for patients undergoing PE with en-bloc sacrectomy between 1994 and 2021 was performed. RESULTS: A total of 363 patients were identified and divided into PS (n=77, 21.2%), ALS (n=247, 68.0%), and HACS (n=39, 10.7%). Indications were: locally advanced (n=92) or recurrent (n=177) rectal cancer, primary other (n=31), recurrent other (n=60), and benign disease (n=3). PS resulted in longer operating time ( P <0.01) and more blood loss ( P <0.01). Patients with HACS had more major nerve (87.2%) and vascular (25.6%) resections ( P <0.01). Vertical rectus abdominis myocutaneous flap repair was less common following HACS (7.7%) than ALS (25.5%) and PS (27.3%) ( P =0.040). R0 rate was 80.8%, 65.8%, and 76.9% following ALS, PS, and HACS, respectively ( P =0.024). Wound-related complications and re-operations were significantly reduced following ALS and HACS compared with PS. CONCLUSIONS: Changing our practice from PS to an anterior approach with ALS or HAS has been safe and improved overall surgical and perioperative outcomes, while maintaining good oncological outcomes. Given the improved perioperative and surgical outcomes, it would be important for surgeons to learn and adopt the anterior sacrectomy approaches.

BACKGROUND: Salvage surgery is the only potentially curative treatment option for recurrent squamous cell carcinoma of the anus. Where adjacent pelvic viscera, soft tissues, and bone are involved, pelvic exenteration with a wide perineal excision may be required to ensure clear surgical margins and increase the likelihood of long-term survival. OBJECTIVE: To report oncological, morbidity, and quality-of-life outcomes of pelvic exenteration for anal squamous cell carcinoma. DESIGN: Cohort study with retrospective analysis of prospectively collected data. SETTINGS: This study was conducted at a high-volume pelvic exenteration center. PATIENTS: Those who underwent pelvic exenteration for anal squamous cell carcinoma between 1994 and 2022. MAIN OUTCOME MEASURES: Local recurrence-free and overall survival, intraoperative and postoperative complication rates, R0 resection rate, and long-term quality-of-life outcomes. RESULTS: Of 958 patients who underwent pelvic exenteration, 66 (6.9%) had anal squamous cell carcinoma. Thirty-two patients (48.5%) were male and the median age was 57 years (range, 31-79). Ten patients (15%) had primary anal squamous cell carcinoma, 49 (74%) had a recurrent tumor, and 7 (11%) had a re-recurrent tumor. Twenty-two patients (33%) and 16 patients (24%) had a major complication and unplanned return to the operating theater, respectively. Of the 62 patients who underwent pelvic exenteration with curative intent, 50 (81%) had R0 resection, and the 5-year overall and local recurrence-free survival rates were 41% and 37%, respectively. R0 resection was associated with a higher 5-year overall survival (50% vs 8%, p < 0.001). The mental health component scores and several individual quality-of-life domains presented improved trajectories postoperatively (all p values <0.05). LIMITATIONS: The generalizability of the findings outside specialist pelvic exenteration centers may be limited. CONCLUSIONS: Morbidity, long-term survival, and quality-of-life outcomes after pelvic exenteration for anal squamous cell carcinoma are comparable to published outcomes of pelvic exenteration for other tumor types.

De los 62 pacientes que se sometieron a una exenteración pélvica con intención curativa, 50 (81%) tuvieron una resección R0, las tasas de supervivencia global y libre de recidiva local a los 5 años fueron del 41% y el 37%, respectivamente. La resección R0 se asoció con una mayor supervivencia general a los 5 años (50% frente a 8%, p < 0,001). Las puntuaciones del componente de salud mental y varios dominios de calidad de vida individuales presentaron trayectorias mejoradas después de la operación (todos los valores de p < 0,05).LIMITACIONES:La generalización de los hallazgos fuera de los centros especializados en exenteración pélvica puede ser limitada.CONCLUSIONES:Los resultados de morbilidad, supervivencia a largo plazo y calidad de vida después de la EP para el carcinoma anal de células escamosas son comparables a los resultados publicados de la exenteración pélvica para otros tipos de tumores.

RESUMO
INTRODUCTION: In patients with locally advanced (LARC) or locally recurrent (LRRC) rectal cancer and bladder involvement, pelvic exenteration (PE) with partial (PC) or radical (RC) cystectomy can potentially offer a cure. The study aim was to compare PC and RC in PE patients in terms of oncological outcome, post-operative complications and quality-of-life (QoL). MATERIALS & METHODS: This was a retrospective cohort analysis of a prospectively maintained surgical database. Patients who underwent PE for LARC or LRRC cancer with bladder involvement between 1998 and 2021 were included. Post-operative complications and overall survival were compared between patients with PC and RC. RESULTS: 60 PC patients and 269 RC patients were included. Overall R0 resection was 84.3%. Patients with LRRC and PC had poorest oncological outcome with 69% R0 resection; patients with LARC and PC demonstrated highest R0 rate of 96.3% (P = 0.008). Overall, 1-, 3- and 5-year OS was 90.8%, 68.1% and 58.6% after PC, and 88.7%, 62.2% and 49.5% after RC. Rates of urinary sepsis or urological leaks did not differ between groups, however, RC patients experienced significantly higher rates of perineal wound- and flap-related complications (39.8% vs 25.0%, P = 0.032). CONCLUSION: PC as part of PE can be performed safely with good oncological outcome in patients with LARC. In patients with LRRC, PC results in poor oncological outcome and a more aggressive surgical approach with RC seems justified. The main benefit of PC is a reduction in wound related complications compared to RC, although more urological re-interventions are observed in this group.

AIM: Pelvic exenteration (PE) has become the standard of care for locally advanced and recurrent rectal cancer. The high short-term morbidity reported from this procedure is well established; however, longer term complications of such radical surgery and their management have not been fully addressed. This study aimed to investigate the incidence, indications and outcomes of long-term (more than 90-day) reoperative surgery in this group of patients, with a focus on the empty pelvis syndrome (EPS). METHODS: Clinical data were extracted from a prospectively maintained database, with additional data pertaining to indications, operative details and outcomes of reoperative surgery obtained from electronic medical records. Patients were excluded if reoperative surgery was endoscopic or radiologically guided, was for the investigation or treatment of recurrent disease, or was clearly unrelated to previous surgery. RESULTS: Of 716 patients who underwent PE, 75 (11%) required 101 reoperative abdominal or perineal procedures, 52 (51%) of which were in 40 (6%) patients for complications of EPS. This group were more likely to have undergone a total PE (65% vs. 43%; P < 0.01) with either major bony (70% vs. 50%; P < 0.01) and/or nerve (40% vs. 25%; P = 0.03) resections at index exenteration. The patho-anatomy, surgical management and outcomes of these patients are described herein, considering separately complications of entero-cutaneous fistula, entero-perineal fistula, small bowel obstruction and local management of perineal wound complications. CONCLUSION: Six per cent of PE patients will require re-intervention for the management of EPS. Reliable strategies for preventing EPS remain elusive; however, surgical management is feasible with acceptable short-term outcomes with the optimum strategy to be selected on an individual patient basis.

OBJECTIVE: To describe quality of life (QOL) and survival outcomes following pelvic exenteration (PE) in old and young patients. BACKGROUND: PE is a management option for complete resection in locally advanced pelvic cancers. Few studies have examined the impact of age on the outcome in elderly patients following PE. PATIENTS AND METHODS: Prospective cohort of consecutive patients undergoing partial and complete PE between 1994 and 2019. Patients were divided into a younger (< 65 years) or older cohort (≥ 65 years) based on their age. QoL was assessed using the SF-36 and FACT-C questionnaires and survival estimated using the Kaplan-Meier method. RESULTS: For 710 patients who underwent PE during the study period, FACT-C total score was significantly better in the elderly during the whole follow-up period of 5 years. Mental component score (SF-36) was significantly better at baseline (p = 0.008) and at 24 months postoperatively (p = 0.042), in the elderly group. Median overall survival was 75 months in the younger cohort and 53 months in the older cohort (p = 0.004). In subgroup analysis, older patients with recurrent or primary rectal cancer had a median survival of 37 and 70 months, respectively. Postoperative cardiovascular complications were greater in the elderly cohort (p < 0.001). CONCLUSIONS: Elderly patients had better overall QoL but lower survival that is probably related to cardiovascular complications rather than to cancer as both groups had similar R0 resection rate. Hence, the elderly population should be considered equally for PE.

OBJECTIVE: To report survival, functional, and quality-of-life (QoL) outcomes after extended radical resection for advanced pelvic tumors with en bloc sciatic or femoral nerve resection. BACKGROUND: Advanced pelvic tumors involving the sciatic or femoral nerve have traditionally been considered inoperable. Small studies have suggested acceptable functional outcomes can be achieved after pelvic exenteration with en bloc sciatic nerve resection. METHOD: Consecutive patients who underwent extended radical pelvic surgery with en bloc resection of the sciatic or femoral nerves at a single center were included. RESULTS: Of 713 radical pelvic resections, 68 patients (9.5%) had en bloc sciatic or femoral nerve resection. Complete sciatic, partial sciatic, and complete femoral nerve resection was performed in 26 (38%), 38 (56%), and 4 patients (6%), respectively. Overall and major postoperative complication rates were 63% and 40%, respectively. R0 resection was achieved in 65% of patients, which translated to 55% and 76% overall and local recurrence-free 5-year survival in those with colorectal cancer. Twenty-two (96%) and 25 (92%) patients could mobilize independently after complete and partial sciatic nerve resection, respectively. Physical QoL was significantly lower at 6 months after surgery compared with baseline (P = 0.041), but returned to baseline at 12 months (P = 0.163). There was no difference in mental or overall QoL at 6 or 12 months compared with baseline. CONCLUSION: En bloc sciatic and femoral nerve resection can be performed during extended radical pelvic resections with morbidity and survival outcomes comparable with existing exenteration literature, including in patients with recurrent rectal cancer. Physical QoL may be impaired after surgery, but returns to baseline by 12 months.

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.

BACKGROUND: Ischiorectal fossa tumors are rare. OBJECTIVE: This study reviews a single institution's series of ischiorectal tumors with comparison against presacral tumors and assesses the utility of preoperative biopsy and angioembolization. DESIGN: This is a retrospective study. SETTINGS: This study was conducted at a quaternary referral center. PATIENTS: All patients with ischiorectal tumor treated between February 1995 and April 2017 were retrospectively reviewed. Tumors extending secondarily into the ischiorectal fossa and inflammatory pathologies were excluded. INTERVENTIONS: Preoperative biopsy, neoadjuvant therapy, angioembolization, and surgical excision of these tumors were reviewed. MAIN OUTCOME MEASURES: Demographic, perioperative, pathological, and oncologic outcomes were evaluated. RESULTS: Twenty-four patients (15 female; median age 54) were identified. Two-thirds were symptomatic. Forty-six percent had a palpable mass. All patients had CT and/or MRI. Fifty percent had a preoperative biopsy, of which 83% were diagnostic, and management was altered in 50%. All patients underwent surgical excision. Fifty-five percent had local excision, 38% had radical pelvic excision, and 8% had total mesorectal excision. Two patients had preoperative angioembolization. Both had successful R0 local excision. Morbidity occurred in 25%, with 1 major complication. There was no 30-day mortality. Histopathology demonstrated 17 soft tissue tumors (3 malignant), 2 GI stromal tumors, 1 neuroendocrine tumor, 1 Merkel cell carcinoma, 1 basaloid carcinoma, 1 epidermal cyst, and 1 lipoma. R0 resection was achieved in 75%. All patients were alive after a median follow-up of 33 months. Four patients developed recurrence at a median 10 months postoperatively. All recurrences were malignant, and 75% had had a R1 resection. LIMITATIONS: This study is limited by its small numbers. The quaternary institution source may introduce bias. CONCLUSIONS: Ischiorectal fossa tumors are heterogeneous and more likely to be malignant than presacral tumors. Biopsy can be useful if a malignant diagnosis is suspected and changes management in 50% of cases. Preoperative embolization may be useful for large vascular tumors. R0 resection is important to minimize recurrence. See Video Abstract at http://links.lww.com/DCR/A779.

BACKGROUND: To perform more radical surgery for complex pelvic malignancies and recurrent colorectal cancer, the surgeon must increasingly operate outside the conventional anatomical planes. Published in 1963 the 'Triangle of Marcille' (lumbosacral triangle) remained primarily of intellectual interest being found lateral to the traditional operating field. However, with the advancement of complex colorectal and gynaecological surgery it now provides a schema to assist surgeons in becoming acquainted with a complex and poorly understood anatomical region. Additionally, it prepares the surgeon for the extent of lateral dissection required to achieve the 'holy grail' for oncological surgery in pelvic malignancy, the complete resection (R0). METHODS: To prosect a preserved cadaver in order to demonstrate, in vivo, the contents and borders of the Triangle of Marcille for the purposes of teaching surgeons and future surgeons. RESULTS: The Triangle of Marcille is both described and demonstrated in vivo, illustrated with diagrams and photographs. The importance of this region to the surgical management of complex colorectal and gynaecological surgery is discussed. CONCLUSION: The Triangle of Marcille is a vital anatomical region for advanced pelvic surgery, particularly in the current era of pelvic exenteration, and especially for those that include the lateral pelvic compartment.

INTRODUCTION: Neoplasms infiltrating the pubic bone have until recently been considered a contraindication to surgery. Paucity of existing published data in regard to surgical techniques and outcomes exist. OBJECTIVE: This study aims to address outcomes of our recently published technique for en bloc composite pubic bone excision during pelvic exenteration. DESIGN: A prospective database was reviewed to identify patients who underwent a partial or complete pubic bone composite excision over a 12-year period. SETTINGS: This study was conducted at a tertiary level exenteration unit. MAIN OUTCOME MEASURES: Primary outcomes measured were resection margin and survival. Secondary outcomes included patient and operative demographics, type of cancer, extent of pubic bone excision, morbidity, and 30-day mortality. RESULTS: Twenty-nine of over 500 patients undergoing exenterations (mean age, 57.9; 20 males) underwent en bloc complete (11 patients) or partial (18 patients) composite pubic bone excision. Twenty-two patients (76%) underwent resection for recurrent as opposed to advanced primary malignant disease of which rectal adenocarcinoma was the most common followed by squamous-cell carcinoma. The median operating time was 10.5 (range, 6-15) hours, and median blood loss was 2971 (range, 300-8600) mL. Seventeen (59%) patients had a concurrent sacrectomy performed mainly S3 and below. A total cystectomy was performed in 26 patients (90%). Fifteen of 20 male patients (75%) had a perineal urethrectomy. A clear (R0) resection margin was achieved in 22 patients (76%) with a 5-year overall survival of 53% after a median follow-up of 3.2 years (r = 1.4-12.3 years). There was no 30-day mortality. Seventy percent of patients experienced morbidity with a pelvic collection the most common. LIMITATIONS: This study was limited because it was a retrospective review, it occurred at a single site, and it used a small heterogeneous sample. CONCLUSION: Within the realm of evolving exenteration surgery, en bloc composite pubic bone excision offers results comparable to central, lateral, and posterior compartment excisions, and, as such, is a reasonable strategy in the management of neoplasms infiltrating the pubic bone.
