To describe quality of life (QOL) and survival outcomes following pelvic exenteration (PE) in old and young patients. 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. 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. 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). 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.

AIM This study aims to assess surgical outcomes and survival following first, second and third pelvic exenterations for pelvic malignancy. METHOD Consecutive patients undergoing pelvic exenteration for pelvic malignancy at a quaternary referral centre from January 1994 and December 2017 were included. Demographics and surgical outcomes were compared between patients who underwent first, second and third pelvic exenterations by generalized mixed modelling with repeated measures. Survival was assessed using Cox proportional hazards models and Kaplan-Meier plots. RESULTS Of the 642 exenterations reviewed, 29 (4.5%) were second and 6 (0.9%) were third exenterations. Patients selected for repeat exenteration were more likely to have asymptomatic local recurrences detected on routine surveillance (P

Aim Reoperative pelvic surgery is rarely hostile and unsafe. Kraske's procedure has historically been used to approach the mid-rectum and to resect retrorectal tumors. However, it provides limited access to the pelvis and is best in the 'virgin' pelvis. We have encountered a select group of patients who required completion proctectomy or resection of a disconnected ileoanal J-pouch where trans-abdominal access to the pelvis was not possible and access to the pelvis could only be safely gained by a prone en bloc sacrectomy. Method We describe a prone approach that provides an alternative route of access to the hostile pelvis. After exposure of the sacrum and coccyx and transection of the sacrum, access to the mesorectal plane is achieved and a proctectomy (or resection of an ileoanal J-pouch) can be completed. The procedure is similar to the Kraske approach but requires a higher and wider exposure similar to the extent of an abdominal resection; however, the operation is performed in 'reverse'. Results We found that this approach was feasible and safe in the previously operated, hostile pelvis. We employed it in one patient to excise a disconnected J-pouch with chronic sepsis and in another patient for a completion proctectomy. Both patients had an uneventful recovery and clear margins were obtained with no complications. Conclusion The en bloc prone sacrectomy approach is a useful alternative in a very select group of patients with difficult trans-abdominal access to the pelvis. Experience in pelvic surgery and identification of clear anatomical landmarks is paramount to avoid catastrophic uncontrollable bleeding.

Tumour infiltration of the lateral pelvic compartment has previously been associated with the highest rate of involved resection margins and carries significant risk of morbidity. In this study, consecutive patients undergoing pelvic exenteration at a single centre between 1994 and 2019 who required en bloc resection of the common or external iliac artery or vein were included.The results demonstrate that complete resection of the iliac vascular system, including resection and reconstruction of the common and external iliac vessels, can be performed safely during pelvic exenteration with oncological outcomes comparable to more central tumours.

Pelvic bone infiltration by locally advanced primary or recurrent pelvic cancer has traditionally been considered an inoperable situation [1–7]. In the last decade, with improved magnetic resonance imaging (MRI) and innovation of surgical technique and technology, pelvic exenteration (PE) surgery with en bloc composite bone resection for anterior, lateral and posterior components of the pelvic bone is now considered the only potential curative option with 5-year survival rates up to 65% when an R0 margin is achieved [8–12]. In addition to a survival benefit, it has also been demonstrated that long-term quality of life (QOL) in survivors of PE with composite pelvic bone excision is comparable to those patients undergoing surgery for primary cancer resections when a R0 margin is achieved. Furthermore, QOL returns to preoperative levels by 3–6 months and is no worse than non-surgical treatments such as radiotherapy and chemotherapy [13–15]. The role of non-operative treatments such as intraoperative radiotherapy (IORT) combined with surgical resection for gross residual disease (R2 margin) remains contentious [16–18]. However, it is now accepted that an R0 resection is the most important factor in predicting overall survival and local control [9–12]. The role of posterior and lateral pelvic bone composite resection with pelvic exenteration has been a more established treatment over the past decade compared with anterior pelvic bone composite resection, perhaps due to a lack of published data on surgical techniques and outcomes for anterior pelvic bone infiltration. Understandably, awareness and referral for assessment is not as common compared with those with lateral or posterior pelvic bone involvement.

Tumour extension beyond the mesorectal plane (ymrT4) occurs in 5-10 per cent of patients with rectal cancer and 10 per cent of patients develop locally recurrent rectal cancer (LRRC) after primary surgery. There is global variation in healthcare delivery for these conditions.An international benchmark trial of the management of ymrT4 tumours and LRRC was undertaken in France and Australia between 2015 and 2017. Heterogeneity in management and operative decision-making were analysed by comparison of surgical resection rates, blinded intercountry reading of pelvic MRI, quality-of-life assessment and qualitative evaluations.Among 154 patients (97 in France and 57 in Australia), 31·8 per cent had ymrT4 disease and 68·2 per cent LRRC. The surgical resection rates were 88 and 79 per cent in France and Australia respectively (P = 0·112). The concordance in operative planning was low (κ = 0·314); the rate of pelvic exenteration was lower in France than Australia both in clinical practice (36 of 78 versus 34 of 40; P 0·001) and in theoretical conditions (10 of 25 versus 50 of 57; P = 0·002). The R0 resection rate was lower in France than Australia for LRRC (25 of 49 versus 18 of 21; P = 0·007) but not for ymrT4 tumours (21 of 26 versus 15 of 15; P = 0·139). Morbidity rates were similar. Patients who underwent non-exenterative procedures had higher scores on the mental functioning subscale at 12 months (P = 0·047), and a lower level of distress at 6 months (P = 0·049). Qualitative analysis highlighted five categories of psychosocial factors influencing treatment decisions: patient, strategy, specialist, organization and culture.This international benchmark trial has highlighted the differences in worldwide treatment of locally advanced and LRRC. Standardized care should improve outcomes for these patients.La extensión del tumor más allá del plano del meso-rrecto (ymrT4) ocurre en el 5-10% de los pacientes con cáncer de recto y el 10% de los pacientes desarrollan recidiva local del cáncer de recto (locally recurrent rectal cáncer, LRRC) después de una cirugía primaria. Existe una variación global en la prestación de la asistencia sanitaria para esta pato-logía. MÉTODOS: Se realizó un ensayo de referencia internacional sobre el manejo de ymrT4 y LRRC en Francia y Australia entre 2015 y 2017. La heterogeneidad en el manejo y la toma de decisiones quirúrgicas se analizaron mediante la comparación de las tasas de resección quirúrgica, la lectura a ciegas de la resonancia magnética (RM) pélvica entre países, la evaluación de la calidad de vida y las evaluaciones cualitativas.De 154 pacientes (97 en Francia versus 57 en Australia), el 32% tenía ymrT4 y el 68% tenía cáncer de recto con recidiva local. Las tasas de resección quirúrgica fueron del 87,6% versus 77,8% (P = 0,112). La tasa de concordancia en la decisión quirúrgica fue baja (coeficiente kappa = 0,314) con una tasa más baja de exenteración pélvica en Francia, tanto en la práctica clínica (46% versus 85%; P0,0001) como en condiciones teóricas (40% versus 88%; P = 0,002). La tasa de resección R0 fue menor en Francia para la LRRC (51% versus 86%, P = 0,007) pero no para el ymrT4 (81% versus 100%, P = 0,139). Las tasas de morbilidad fueron similares. Los pacientes que se sometieron a procedimientos no exenterativos tuvieron una subescala de funcionamiento mental más alta a los 12 meses (P = 0,04) y un nivel de angustia más bajo a los 6 meses (P = 0,04). El análisis cualitativo destacó 5 categorías de factores psicosociales que afectaron a la decisión del tratamiento: paciente, estrategia, especialista, organización y cultura. CONCLUSIÓN: Este ensayo de referencia internacional destaca las diferencias en el tratamiento mundial del cáncer de recto localmente avanzado y de la LRR. La aten-ción estandarizada debería mejorar los resultados para estos pacientes.

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.

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.

Novel technique of management of colonic pseudo-obstructing using colonoscopy guided insertion of decompression tube.

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.

Stapled hemorrhoidectomy (SH) as described by Longo is a recently added option for hemorrhoid surgery. Interest in SH has been principally driven by the fact that conventional excision hemorrhoidectomy (EH) has been an extremely painful procedure because it involves excision of hemorrhoidal tissue along the extremely sensitive anoderm. SH, on the other hand, has been shown to be associated with decreased postoperative pain because it does not involve the sensate anal mucosa below the dentate line. To date there have been many randomized controlled studies comparing circular SH with traditional excision techniques. Despite proven early postoperative advantages for SH, the long-term benefits and effect on patient quality of life (QOL) compared with EH still remain to be debated. This study aimed to evaluate long-term patient outcomes via a validated health-related QOL survey. QOL measures were satisfactory in both groups across all subscales of physical health summary measures and mental health summary measures. This coincided with Wexner continence scores, which were also satisfactory, with a median of 0 in both groups. QOL, continence scores, and long-term symptom follow-up are similar in patients who undergo SH or EH.

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.This study aims to address outcomes of our recently published technique for en bloc composite pubic bone excision during pelvic exenteration.A prospective database was reviewed to identify patients who underwent a partial or complete pubic bone composite excision over a 12-year period.This study was conducted at a tertiary level exenteration unit.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.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.This study was limited because it was a retrospective review, it occurred at a single site, and it used a small heterogeneous sample.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.

Introduction Radical surgery with pelvic exenteration offers the only potential for cure in patients with locally advanced primary rectal cancer. This study describes the clinical and patient-reported quality of life outcomes over 12 months for patients having pelvic exenteration for locally advanced primary rectal cancer at a specialised centre for pelvic exenteration. Methods Clinical data of consecutive patients undergoing pelvic exenteration for locally advanced primary rectal cancer and patient-reported outcomes were collected at baseline, hospital discharge and at 1, 3, 6, 9 and 12 months. Patient-reported outcomes included cancer-specific quality of life (QoL) and physical and mental health status. Quality of life trajectories were modelled over the 12 months from the date of surgery using linear mixed models. Results 104 patients with locally advanced rectal cancer underwent pelvic exenteration at Royal Prince Alfred Hospital, Sydney, between December 1994 and October 2014. Complete soft tissue exenteration was performed in 38%. A clear margin was obtained in 86% with a 62% overall five-year survival. QoL outcome questionnaires were completed by 62% of patient cohort. The average FACT-C score returned to pre-surgery QoL by 2 months after surgery, and the average QoL continued to increase slowly over the 12 months. Conclusion Our results support an aggressive approach to advanced primary rectal cancer and lend weight to the oncological role of pelvic exenteration for this group of patients. Quality of life improves rapidly after pelvic exenteration for locally advanced primary rectal cancer and continues to improve over the first year.

This article describes a novel technique for en bloc resection of locally recurrent rectal cancer that invades the high sacral bone (above S3). The involved segment of the sacrum is mobilised with osteotomes during an initial posterior approach before an anterior abdominal phase where the segment of sacral bone is delivered with the specimen. This allows en bloc resection of the involved sacrum while preserving uninvolved distal and contralateral sacral bone and nerve roots. The goal is to obtain a clear bony margin and offer a chance of cure while improving functional outcomes by maintaining pelvic stability and minimising neurological deficit.

Despite advances in the rates of total mesorectal excision (TME) for rectal cancer surgery, decreased local recurrence rates and increased 5-year survival, there still exists large variation in the quality of treatment received. Up to 30 per cent of rectal cancers are locally advanced at presentation and approximately 5-10 per cent still breach the mesorectal plane and invade adjacent structures despite neoadjuvant therapy. With the evolution of extended resections for rectal cancers beyond the TME plane, proponents advocate that these resections should be performed only in specialist centres. The aim was to assess the prognostic factors and patterns of failure after beyond TME surgery for T4 rectal cancers.Data were collected from prospective databases at three high-volume institutions specializing in beyond TME surgery for T4 rectal cancers between 1990 and 2013. The primary outcome measures were overall survival, local recurrence and patterns of first failure.Three hundred and sixty patients were identified. The negative resection margin (R0) rate was 82·8 per cent (298 patients) and the local recurrence rate was 12·5 per cent (45 patients). The type of surgical procedure (Hartmann's: hazard ratio (HR) 4·49, 95 per cent c.i. 1·99 to 10·14; P = 0·002) and lymphovascular invasion (HR 2·02, 1·08 to 3·77; P = 0·032) were independent predictors of local recurrence. The 5-year overall survival rate for all patients was 61 (95 per cent c.i. 55 to 67) per cent. The 5-year cumulative incidence of first failure was 8 per cent for local recurrence, 6 per cent for local and distant disease, and 18 per cent for distant disease.This study has demonstrated that a coordinated approach in specialist centres for beyond TME surgery can offer good oncological and long-term survival in patients with T4 rectal cancers.A pesar de las mejoras en los porcentajes de extirpación total del mesorrecto (total mesorectal excision, TME) en la cirugía de cáncer de recto, la disminución de los porcentajes de recidiva local y el aumento de la supervivencia a 5 años, todavía existe una gran variabilidad en la calidad del tratamiento recibido. Hasta el 30% de los cánceres de recto están localmente avanzados en el momento del diagnóstico y aproximadamente el 5-10% sobrepasarán el plano mesorrectal e invadirán las estructuras adyacentes a pesar del tratamiento neoadyuvante. Con la evolución de las resecciones ampliadas para los cánceres de recto que sobrepasan el plano de la TME, los defensores recomiendan que estas resecciones solo se realicen en centros especializados. El objetivo fue evaluar los factores pronósticos y los patrones de recidiva después de la cirugía ampliada más allá de la TME para los cánceres de recto T4. MÉTODOS: Los datos se recogieron a partir de bases de datos prospectivas de tres instituciones de alto volumen especializadas en resecciones ampliadas más allá de la TME para el cáncer de recto T4 entre 1990 y 2013. Los criterios de valoración principal fueron la supervivencia global, la recidiva local y los patrones de la primera recidiva.Se identificaron 360 pacientes. El margen de resección fue negativo (R0) en el 82,8% (n = 298) y el porcentaje de recidiva local fue de 12,5% (n = 45). El tipo de cirugía realizada (Hartmann: cociente de riesgos instantáneos, hazard ratio, HR 4,49; i.c. del 95%: 1,99-10,14; P = 0,002) y la invasión linfovascular (HR 2,02; i.c. del 95%: 1,08-3,77; P = 0,032) fueron factores predictivos independientes de recidiva local. La supervivencia global a 5 años para todos los pacientes fue del 61% (i.c. del 95%: 55-67). La incidencia acumulada a los 5 años de la primera recidiva fue de 8% para la recidiva local, 6% para la recidiva local y a distancia, y 18% para la recidiva a distancia. CONCLUSIÓN: Este estudio demuestra que un abordaje coordinado en centros especializados para cirugía más allá de la TME puede ofrecer una buena supervivencia oncológica y a largo plazo en pacientes con cáncer de recto T4.

This report is of a rare case involving a 27-year-old female who presented to the hospital with the pathological couplet of colocolic intussusception and cecal bascule causing bowel obstruction. Up to the time of presentation to the hospital, this patient had not undergone a full investigation for a known iron deficiency, anemia. Subsequently, during the emergency admission and after having an operative surgical procedure, the patient was found to have both a congenitally malpositioned cecum and a benign colonic polyp-forming condition. The pertinent issues about this unusual case to be highlighted are its ambiguous clinical presentation; uncommon gender and age group for either condition; the simultaneous occurrence of dual anatomical anomalies; and the uncommon benign etiology of causes of bowel obstruction in adults.

This case report describes an otherwise well 20-year-old male who presented to hospital with vague, long-standing abdominal symptoms and was found to have peritoneal encapsulation.

Background Involvement of the lateral compartment remains a relative or absolute contraindication to pelvic exenteration in most units. Initial experience with exenteration in the authors' unit produced a 21 per cent clear margin rate (R0), which improved to 53 per cent by adopting a novel technique for en bloc resection of the iliac vessels and other side-wall structures. The objective of this study was to report morbidity and oncological outcomes in consecutive exenterations involving the lateral compartment. Methods Patients undergoing pelvic exenteration between 1994 and 2014 were eligible for review. Results Two hundred consecutive patients who had en bloc resection of the lateral compartment were included. R0 resection was achieved in 66·5 per cent of 197 patients undergoing surgery for cancer and 68·9 per cent of planned curative resections. For patients with colorectal cancer, a clear resection margin was associated with a significant overall survival benefit (P = 0·030). Median overall and disease-free survival in this group was 41 and 27 months respectively. Overall 1-, 3- and 5-year survival rates were 86, 46 and 35 per cent respectively. No predictors of survival were identified on univariable analysis other than margin status and operative intent. Excision of the common or external iliac vessels or sciatic nerve did not confer a survival disadvantage. Conclusion The continuing evolution of radical pelvic exenteration techniques has seen an improvement in R0 margin status from 21 to 66·5 per cent over a 20-year interval by routine adoption of a more lateral anatomical plane. Five-year overall survival rates are comparable with those for more centrally based tumours.

Background The purpose of this study was to analyse retrospectively the pooled results after pelvic exenteration for locally advanced T4 rectal cancer. Historically, patients with T4 rectal cancers requiring pelvic exenteration have been offered only palliative surgery or no operation. Methods The basic treatment principle was preoperative (chemo)radiotherapy, radical surgery and, in some patients, adjuvant chemotherapy. Risk factors for local recurrence, distant metastases and overall survival were studied in univariable and multivariable analyses. Results Ninety-five patients with T4 rectal cancer who underwent pelvic exenteration in two tertiary referral centres up to 2013 were studied. Clear margins (R0) were achieved in 87 per cent of patients. Adjuvant chemotherapy was administered in 33 per cent, independent of the resection margin, lymph node status and postoperative T category. The 5-year local recurrence rate was 17 per cent, with a distant metastasis rate of 16 per cent and overall survival rate of 62 per cent. In multivariable analysis the only factor associated with death was omission of adjuvant chemotherapy (P = 0·016). The effect of adjuvant chemotherapy was more pronounced in the elderly: patients aged over 70 years who had chemotherapy had a 5-year overall survival rate of 80 per cent, compared with 39 per cent of elderly patients who did not receive chemotherapy (P = 0·019). Conclusion Pelvic exenteration led to an R0 resection rate of 87 per cent for T4 rectal cancer, giving good local control and overall survival comparable to population-based colorectal cancer survival rates. Adjuvant chemotherapy may improve overall survival further, even in the elderly.

Recurrent and advanced primary pelvic cancers present a complex clinical issue requiring multidisciplinary care and radical extended surgery. Sacral resection is necessary for tumors that invade posteriorly but is associated with increased morbidity and mortality.This study aimed to analyze the morbidity and survival associated with pelvic exenteration involving sacrectomy for advanced pelvic cancers at a single institution.This study used patient demographics, operative and pathologic reports, and prospective survival data to determine factors affecting patient outcomes.Data were collected for patients who had operations between July 1998 and April 2012 at Royal Prince Alfred Hospital.One hundred patients underwent pelvic exenteration with a sacrectomy for advanced pelvic cancers. Sacrectomy was performed for 18 primary and 61 recurrent rectal cancers, 17 anal cancers, and 4 other cancers.This study looked at postoperative major and minor morbidity rates, as well as disease-free and overall survival rates after sacral resection. It compared the outcomes of high sacrectomy (at or above S2) versus low sacrectomy.Clear margins were achieved in 72 of 100 patients. The overall complication rate was 74% (43% major and 67% minor) with no 30-day or in-hospital mortality. Estimated overall and disease-free survival rates after curative resection were 38% and 30% at 5 years. Involved margins (p = 0.006), lymph node involvement (p = 0.008), and anterior organ invasion (p = 0.008) had a negative impact on patient survival. High sacrectomy increased the incidence of neurologic deficit postoperatively (p = 0.04) but did not alter the rate of R0 resection or patient survival.Retrospective data were required to analyze patient morbidity, as well as operative and pathologic factors.This series supports sacral resection for curative surgery in advanced pelvic cancers, achieving excellent R0 and long-term survival rates. Cortical bone invasion and high sacrectomy were not contraindications to surgery and had acceptable outcomes.

The risk of significant haemorrhage in pelvic exenterative surgery requiring sacrectomy has been well described. Patients requiring a sacrectomy above S3 are placed in the prone position, posing an increased challenge to gaining control of haemorrhage when it occurs. We describe a technique of pre-emptive control of the internal iliac vein and its three named tributaries to tame the pelvis prior to sacrectomy. A retrospective, descriptive analysis was performed on a cohort of 25 consecutive patients operated on by one of the authors (AA E) between January 2005 and December 2010; all of whom underwent pre-emptive internal iliac vein triple tributary venous ligation, either unilaterally or bilaterally prior to sacrectomy above the level of S3. The cohort of patients was a heterogenous group ranging in age from 20 to 80 (mean 46.2) years, with primary tumours in 19 (76%), and secondary tumours in 6 (24%). Median operating time was 8.5 h (range 2.32–19.67 h). Median blood loss was 5500 mL (range 1600–18000 mL), with associated median transfusion of packed red blood cells of 9 units (range 0–34 units). Average stay in the intensive care unit was 1 day (range 0–10 days), with a median length of hospital stay of 18 days (range 5–148 days). There was no intraoperative mortality, with one death at 30 days secondary to gram-negative septicaemia. Postoperative morbidity occurred in 17 (68%) patients. Our results show that pre-emptive triple tributary internal iliac vein ligation is feasible for taming the pelvis prior to sacrectomy in the prone position where control of significant haemorrhage can prove challenging. The technique has broader relevance for visceral resections in the pelvis involving the pelvic side walls.

PURPOSE: Lateral pelvic recurrence is considered a poor prognostic variable and a relative contraindication to surgery because of the difficulty in achieving clear margins. The aim of this study was to outline our surgical approach to lateral pelvic sidewall involvement and assess the oncologic and long-term outcomes. METHODS: A retrospective review of a prospective database was performed. Patient demographics, cancer and operative details, intent, margins, lymph node status, rerecurrence at resection site, follow-up, living and death details were assessed. RESULTS: En bloc lateral pelvic wall dissection and vascular resection with pelvic exenteration was performed in 36 patients of 107 exenterations. All patients underwent surgery with curative intent. Negative margins were achieved in 19 patients (53%). Ten patients (28%) developed recurrence at the site of resection compared with 26 patients (72%) who remained disease free at the site of surgery. Sixteen patients (46%) are disease-free with the average disease-free interval of 30 months. Twenty-five patients (69%) are alive with a mean follow-up of 19 months. No mortalities occurred in this cohort of patients. CONCLUSION: Despite the complexity of this technique, it is safe and feasible. Careful preoperative radiologic assessment and a multidisciplinary approach are paramount to achieving clear margins.

Objective: To assess the outcomes and patterns of treatment failure of patients who underwent pelvic exenteration surgery for recurrent rectal cancer. Background: Despite advances in the management of rectal cancer, local recurrence still occurs. For appropriately selected patients, pelvic exenteration surgery can achieve long-term disease control. Methods: Prospectively maintained databases of 5 high volume institutions for pelvic exenteration surgery were reviewed and data combined. We assessed the combined endpoints of overall 5-year survival, cancer-specific 5-year mortality, local recurrence, and the development of metastatic disease. Results: Five hundred thirty-three patients who had undergone surgery for locally recurrent rectal cancer were identified. Five-year cancer-specific survival for patients with a complete (R0) resection is 44%, which was achieved in 59% of patients. For those with R1 and R2 resections, the 5-year survival was 26% and 10%, respectively. Radical resection required sacrectomy in 170 patients (32%), and total cystectomy in 105 patients (20%). Treatment failure included local recurrence alone in 75 patients (14%) and systemic metastases with or without local recurrence in 226 patients (42%). Chemoradiotherapy before exenteration was associated with a significant (P < 0.05) improvement in overall 5-year cancer-specific survival for those patients with an R0 resection. Postoperative chemotherapy did not alter outcomes. Conclusions: R0 resection of the pelvic recurrence is the most significant factor affecting overall and disease-free survival. The surgery is complex and often highly morbid, and where possible patients should be given perioperative chemoradiotherapy. Further investigations are required to determine the role of adjuvant chemotherapy.

Malignant infiltration of the pubic bone traditionally is considered inoperable. Consequently, there is little published on surgical approaches to resection of the anterior pelvic bone. En bloc partial or complete pubic bone excision can be performed depending on the degree of involvement.This article describes our surgical approach of pelvic exenteration with en bloc composite pubic bone excision.The surgical technique describes 2 distinct aspects of the surgery, first, a perineal as opposed to abdominal transection of the urethra, and, second, varying extents of en bloc pubic bone excision.This study was conducted at a tertiary care hospital.Pelvic tumors infiltrating the pubic bone require radical en bloc composite bone resection to achieve an R0 margin that should translate to longer-term survival versus nonoperative treatments.Results of our study are currently under review.As the magnitude of pelvic exenteration surgery continues to evolve for all compartments of the pelvis, malignant infiltration of the anterior pelvic bone should not be considered a contraindication to surgery.

INTRODUCTION: There is little information about the impact of pelvic exenteration on patients' quality of life. This study aimed to measure quality of life for longer-term disease-free survivors after pelvic exenteration. METHODS: A retrospective review to identify patients who underwent pelvic exenteration for locally advanced primary or recurrent rectal cancer was performed. Telephone interviews to assess quality of life were performed using the Short Form 36 version 2 and Functional Assessment of Cancer Therapy-Colorectal instruments. Responses were compared with normative data from the general Australian population and patients with rectal cancer who underwent low anterior resection or abdominoperineal excision. RESULTS: Of 75 patients with rectal cancer, 44 were alive and 37 (84%) completed the quality-of-life assessment a median 47 months after pelvic exenteration. Functional Assessment of Cancer Therapy scores in the survivors were good (107) and comparable to those for patients who had a low anterior resection or abdominoperineal excision a median of 3 months previously (106). Although the physical component summary scale of the Short Form 36 was lower in pelvic exenteration patients (44.7) than for the Australian population, the mental component summary scale was high (53.5) and comparable. CONCLUSION: Despite the small sample, long-term quality of life in survivors of pelvic exenteration for rectal cancer is comparable to early results following primary rectal cancer resection and to mental but not physical norm-based population scores.

Background: Stapled haemorrhoidectomy (SH) described by Longo has been a recently added option for hemorrhoid surgery. Interest in SH has been principally driven by the fact that conventional excision haemorrhoidectomy (EH) has been an extremely painful procedure as it involves excision of haemorrhoidal tissue along the extremely sensitive anoderm. SH on the other hand has been shown to be associated with decreased postoperative pain, as it does not involve the sensate anal mucosa below the dentate line. To date there have been many randomized controlled studies comparing circular stapled haemorrhoidectomy with traditional excision techniques. Despite proven early postoperative advantages for SH the long-term benefits and effect on patients quality of life (QOL) compared to EH still remains to be debated. Methods: To evaluate long-term patient outcomes via a validated health related QOL survey. Results: QOL measures were satisfactory in both groups across all subscales of physical health summary ...
