Background: Although pain may persist for patients who undergo pelvic exenteration for treatment of locally recurrent rectal cancer, studies exploring patient experience of postoperative pain and its management remains limited., Objective: This study aimed to explore patient experiences of postoperative chronic pain and management following pelvic exenteration., Design: Qualitative cohort study of patients who have undergone pelvic exenteration for locally recurrent rectal cancer., Settings: The study was conducted through one-on-one semi-structured telephone interviews., Patients: Seventeen patients with locally recurrent rectal cancer who underwent pelvic exenteration between January 2018 and December 2020 were included., Main Outcome Measures: Semi-structured interviews explored participants' experiences of pain including its impact on life and management strategies at six and twelve months following exenteration. Interview transcripts were analyzed by two researchers using inductive thematic analysis., Results: Participant experiences of pain following exenteration are reflected by three themes identified: 1) adapting to long-term consequences of pelvic exenteration including pain, 2) reluctance to take pain medications, 3) engaging multidisciplinary care team is essential to post-pelvic exenteration chronic pain management. Several participants reported ongoing intermittent pain following surgery that significantly affected various aspects of their lives. This prompted participants to adapt their lifestyle and explore alternative pain relief methods as some were hesitant to rely on analgesics., Limitations: The small sample size from a single center whereby all patients underwent curative pelvic exenteration for lower recurrent rectal cancer with none undergoing the procedure for palliation limits the generalizability of the results of this study., Conclusions: While chronic pain following pelvic exenteration for locally recurrent rectal cancer interferes with patient's postoperative quality of life, analgesia use was influenced by pain habituation and fear of dependence on pain medications. Our findings emphasize the further need to investigate a multidisciplinary approach, including non-pharmacological methods, for optimization of pain outcomes following pelvic exenteration.

Introduction: Pelvic exenteration provides significant survival benefits for selected patients diagnosed with locally advanced rectal cancer. However, in-hospital postoperative morbidity such as abdominal abscess, sepsis, and anastomotic leak remain highly prevalent, which can have short/long-term impacts on patient quality of life (QoL). The aim of this study was to determine the influence of postoperative morbidity on QoL outcomes in patients following pelvic exenteration., Methods: This prospective cohort study included patients who underwent pelvic exenteration at a tertiary teaching hospital in Sydney, between 2008 and 2023. QoL measures were collected at baseline, 6, 12, 18, 24, 36, 48, and 60 months using the short-form 36 (SF-36v2) survey. The predictors included variables relating to postoperative morbidity, including hospital and ICU length of stay (LOS), post-discharge mortality and the number of postoperative complications. Mixed-effects analyses were used to determine the influence of these postoperative outcomes on physical and mental QoL trajectories., Results: This study included 674 patients, with a median age of 61 years. Shorter hospital and ICU LOS, and fewer or no postoperative complications were associated with higher physical QoL scores across all time points. Conversely, postoperative morbidity did not exhibit a significant impact on mental QoL scores. Furthermore, there was a longitudinal improvement in mental QoL outcomes compared to baseline, independent of postoperative morbidity., Conclusion: Postoperative morbidity significantly impacted physical QoL outcomes after pelvic exenteration, whereas mental QoL outcomes were not influenced. Interventions aimed at mitigating postoperative morbidity may hold the potential to enhance long-term QoL outcomes following pelvic exenteration., (Copyright © 2024 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Aim: Early-onset colorectal cancer (EOCRC) patients are more likely to have advanced disease and undergo more aggressive treatment modalities. However, current literature investigating the health-related quality of life (HRQoL) of EOCRC patients is scarce. This study aimed to determine the HRQoL of an Australian cohort of EOCRC patients including a subset who underwent pelvic exenteration (PE) or cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC)., Method: A cross-sectional study of EOCRC patients treated at the Royal Prince Alfred Hospital, Sydney Australia was performed. Patients were divided into groups based on the time interval from their index operation: ≤2 years and >2 years. HRQoL was evaluated using the SF-36v2 questionnaire., Results: A total of 50 patients were included. For patients ≤2 years from surgery, the median physical component summary (PCS) and mental health component summary (MCS) scores were 53.3 (36.4-58.9) and 47.3 (37.5-55.7). In the >2 years group, the median PCS and MCS scores were 50.6 (43.3-57.7) and 50.2 (39.04-56.2), respectively. Stage I (vs. stage II) disease and emergency (vs. elective) surgery conferred poorer PCS scores in patients ≤2 years from surgery. No other variables impacted PCS or MCS scores in EOCRC patients in either group., Conclusions: HRQoL of EOCRC patients was equivocal to the Australian population. Having an earlier stage of diagnosis and emergency index operation was associated with poorer levels of physical functioning in patients ≤2 years from surgery. However, because of the limitations of this study, these findings require validation in future large-scale prospective research., (© 2024 The Author(s).

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

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.

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.

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., (© 2023 The Authors.

Background: Peritoneal malignancies are challenging cancers to manage. While cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS and HIPEC), may offer a cure, it is a radical procedure associated with significant morbidity. Pre-emptive identification of deconditioned patients for optimization may mitigate surgical risk. However, the difficulty lies in identifying a cost-effective predictive tool. Recently, there has been interest in sarcopenia, which may occur due to malignancy. The purpose of this study was to assess the utility of sarcopenia at predicting post-operative outcomes., Methods: A quaternary-centre retrospective study of CRS and HIPEC patients (2017-2020), were conducted to determine the association between pre-operative sarcopenia on oncological (peritoneal carcinomatosis index (PCI)) and surgical outcomes (complications). Sarcopenia from lumbar CT-images were measured using Slice-o-matic™. Statistical differences were analysed using Mann-Whitney U and Chi-squared test., Results: Cohort analysis (n = 94) found 40% had sarcopenia, majority were female (53.2%), and average age of 55 years. The major pathologies was colorectal cancer (n = 39, 41.5%), appendix adenocarcinoma (n = 21, 22.3%), and pseudomyxoma peritonei (PMP) (n = 19, 20.2%). Sarcopenia was associated with decreased weight, 72.7 versus 82.2 kg (P = 0.014) and shorter survival, 1.4 versus 2.1 years (95% CI, 1.09-3.05, P = 0.032). Median PCI (excluding PMP) was 11 (6-18) and median PCI (only PMP) was 25 (11-32). Post-operatively, sarcopenia patients experienced more complications (72.5% vs. 64.8%, P = 0.001)., Conclusion: Pre-emptive identification of sarcopenia may be a useful prognostic indicator and predictor of post-operative outcomes in CRS and HIPEC. For oncological patients, sarcopenia may be an indicator of patients requiring targeted pre-operative rehabilitation, or advanced disease requiring further treatment., (© 2023 The Authors.

Aim: Pelvic exenteration surgery can improve survival in people with advanced colorectal cancer. This systematic review aimed to review pain intensity and other outcomes, for example the management of pain, the relationship between pain and the extent of surgery and the impact of pain on short-term outcomes., Method: Electronic databases were searched from inception to 1 May 2021. We included interventional studies of adults with any indication for pelvic exenteration surgery that also reported pain outcomes. Risk of bias was assessed using ROBINS-1., Results: The search found 21 studies that reported pain following pelvic exenteration [n = 1317 patients, mean age 58.4 years (SD 4.8)]. Ten studies were judged to be at moderate risk of bias. Before pelvic exenteration, pain was reported by 19%-100% of patients. Five studies used validated measures of pain intensity. No study measured pain at all three time points in the surgical journey. The presence of pain before surgery predicted postoperative adverse pain outcomes, and pain is more likely to be experienced in those who require wider resections, including bone resection., Conclusion: Considering that pain following pelvic exenteration is commonly described by patients, the literature suggests that this symptom is not being measured and therefore addressed., (© 2022 The Authors.

Aim: This study aimed to investigate the implementation and pain-related outcomes of a peri-operative pain-management regimen for patients undergoing pelvic exenteration surgery at a university teaching hospital., Method: This is a single-site prospective observational cohort study involving 100 patients who underwent pelvic exenteration surgery between January 2017 and December 2018. A pain-management algorithm regarding the use of opioid-sparing multimodal analgesia was developed between the departments of anaesthesia, pain management and intensive care. The primary outcomes were: compliance with a pain-treatment algorithm compared with a similar retrospective surgical patient cohort in 2013-2014; and requirements for regular doses of opioid analgesia at discharge, measured in oral morphine equivalent daily dose (oMEDD)., Results: Following the introduction of a pain-management algorithm, regional anaesthesia techniques (spinal anaesthesia, transversus abdominus plane block, preperitoneal catheters or epidural analgesia) were used in 83/98 (84.7%) of the 2017-2018 cohort compared with 13/73 (17.8%) of the 2013-2014 cohort (p < 0.001). There was a reduction in the median dose of opioid analgesics (oMEDD) at time of discharge, from 150 mg (interquartile range [IQR]: 75.0-235.0 mg) in the 2013-2014 cohort to 10 mg (IQR: 0.00-45.0 mg) in the 2017-2018 cohort (p < 0.001). There was no change in pain intensity (assessed using the Verbal Numerical Rating Score) or oMEDD in the first 7 days following surgery., Conclusion: Since implementation of a novel peri-operative pain-treatment algorithm, the use of opioid-sparing regional techniques and preperitoneal catheters has increased. Additionally, the dose of opioids required at the time of discharge has reduced significantly., (© 2022 The Authors.

Background: Pre-operative physical status and its association with post-operative surgical outcomes is poorly understood in patients with peritoneal malignancy who undergo cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). The aims of this study were to determine the pre-operative physical function in patients having CRS-HIPEC and investigate the association between physical function and post-operative outcomes., Patients and Methods: Patients undergoing CRS-HIPEC between 2017 and 2021 were recruited at a single quaternary referral hospital in Sydney, Australia. The primary physical function measures were the 6-min walk test (6MWT) and the five-times sit to stand test (5STS). Data were collected pre-operatively and at post-operative day 10, and were analysed according to pre-operative patient characteristics and post-operative outcomes such as length of hospital stay (LOS) and complications., Results: The cohort of patients that participated in functional assessments consisted of 234 patients, with a median age of 56 years. Patients having CRS-HIPEC performed worse on the 6MWT pre-operatively compared with the general Australian population (p < 0.001). Post-operatively, these patients experienced a further deterioration in 6MWT and 5STS performance and the degree of the post-operative decline in function was associated with post-operative morbidity. A higher level of pre-operative physical function was associated with shorter LOS and minor post-operative complications., Conclusions: Patients who have undergone CRS-HIPEC were functionally impaired pre-operatively compared with the general population and experience a further deterioration of physical function post-operatively. A higher level of pre-operative physical function is associated with minor post-operative morbidity, which is highly relevant for pre-operative optimisation of patients with cancer., (© 2022.

Background: Although pelvic exenteration remains the only curative option for locally advanced rectal cancer and locally recurrent rectal cancer, only limited evidence is available on the differences in surgical and quality-of-life outcomes between the two., Objective: This study aimed to compare surgical outcomes and identify any differences or predictors of quality of life of patients with locally advanced rectal cancer and locally recurrent rectal cancer undergoing pelvic exenteration., Design: This was a cohort study., Setting: This study was conducted at Royal Prince Alfred Hospital, Sydney, Australia., Patients: This study included patients with locally advanced rectal cancer and locally recurrent rectal cancer who underwent pelvic exenteration between July 2008 and March 2019., Main Outcome Measures: The main outcome measures included Short Form 36 version 2 and Functional Assessment of Cancer Therapy-Colorectal score., Results: A total of 271 patients were included in this study. Locally advanced rectal cancer patients had higher rates of R0 resection ( p = 0.003), neoadjuvant chemoradiotherapy ( p < 0.001), and had greater median overall survival (75.1 vs. 45.8 months), although the latter was clinically but not statistically significant. There was a higher blood loss ( p < 0.001), longer length of stay ( p = 0.039), and longer operative time ( p = 0.002) in the locally recurrent rectal cancer group. This group also had a higher mean baseline physical component summary score and Functional Assessment of Cancer Therapy-Colorectal score; however, there were no significant differences in complications or quality-of-life outcomes between with the two groups at any time points postoperatively up to 12 months., Limitation: The study was from a specialized experienced center, which could limit its generalizability., Conclusions: Patients with locally recurrent rectal cancer tend to require a more extensive surgery with a longer operative time and more blood loss and longer recovery from surgery, but despite this, their quality of life is comparable to those with locally advanced rectal cancer.

Hubo una mayor pérdida de sangre ( p < 0,001), una estancia más prolongada ( p = 0,039) y un tiempo operatorio más prolongado ( p = 0,002) en el grupo de cáncer de recto localmente recurrente. También tenían una puntuación de componente físico inicial media más alta y una puntuación de Evaluación funcional de la terapia del cáncer colorrectal; sin embargo, no hubo diferencias significativas en las complicaciones o los resultados de la calidad de vida entre los dos grupos en ningún momento después de la operación hasta los 12 meses.LIMITACIÓN:El estudio fue de un centro especializado con experiencia, lo que podría limitar su generalización.CONCLUSIONES:Los pacientes con cáncer de recto localmente recurrente tienden a requerir una cirugía más extensa con un tiempo operatorio más largo y más pérdida de sangre y una recuperación más prolongada de la cirugía, pero a pesar de esto, su calidad de vida es comparable a aquellos con cáncer de recto localmente avanzado.

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are the standard treatment for selected patients with peritoneal malignancy. The optimal means of assessing risk prior to these complex operations is not known. This study explored the associations between preoperative cardiopulmonary exercise testing (CPET) variables and postoperative outcomes following elective CRS and HIPEC. This study included patients who underwent routine preoperative CPET prior to elective CRS and HIPEC at Royal Prince Alfred Hospital in Sydney between July 2017 and July 2020. CPET was performed using a cycle ergometer and measured peak oxygen uptake (VO 2 peak) and anaerobic threshold (AT). Outcomes included in-hospital morbidity, length of intensive care unit (ICU) stay and hospital stay. The associations between preoperative CPET variables and postoperative morbidity were assessed using univariate and multivariate analyses. A total of 129 patients were included. Mean age was 56 years (standard deviation (SD) 12.5 years), and colorectal cancer was the most common indication for CRS and HIPEC. The overall complication rate was 69%, and two (1.6%) patients died in hospital. Patients who did not develop any postoperative complication had slightly higher preoperative AT and VO 2 peak and shorter length of hospital stay. Data in this study support the role of CPET prior to CRS and HIPEC as an adjunct to improve risk assessment.

Purpose: We quantified the contributions of prognostic factors to socioeconomic disparities in colorectal cancer survival in a large Australian cohort., Methods: The sample comprised 45 and Up Study participants (recruited 2006-2009) who were subsequently diagnosed with colorectal cancer. Both individual (education attained) and neighbourhood socioeconomic measures were used. Questionnaire responses were linked with cancer registrations (to December 2013), records for hospital inpatient stays, emergency department presentations, death information (to December 2015), and Medicare and Pharmaceutical Benefits claims for subsidised procedures and medicines. Proportions of socioeconomic survival differences explained by prognostic factors were quantified using multiple Cox proportional hazards regression., Results: 1720 eligible participants were diagnosed with colorectal cancer after recruitment: 1174 colon and 546 rectal cancers. Significant colon cancer survival differences were only observed for neighbourhood socioeconomic measure (p = 0.033): HR = 1.55; 95% CI 1.09-2.19 for lowest versus highest quartile, and disease-related factors explained 95% of this difference. For rectal cancer, patient- and disease-related factors were the main drivers of neighbourhood survival differences (28-36%), while these factors and treatment-related factors explained 24-41% of individual socioeconomic differences. However, differences remained significant for rectal cancer after adjusting for all these factors., Conclusion: In this large contemporary Australian cohort, we identified several drivers of socioeconomic disparities in colorectal cancer survival. Understanding of the role these contributors play remains incomplete, but these findings suggest that improving access to optimal care may significantly reduce these survival disparities., (© 2021.

Background: There is clinical uncertainty regarding an association between preoperative functional capacity of cancer patients, and postoperative outcomes. The aim of this systematic review and meta-analysis is to investigate whether poor performance on preoperative six-minute walk test (6MWT) or five-times sit to stand test (5STS) is associated with worse postoperative complication rates and prolonged length of hospital stay (LOS) in cancer patients., Methods: An electronic search was performed from earliest available record to 26th February 2021 in MEDLINE, Embase and AMED. Studies investigating the association between preoperative physical function (measured using either 6MWT or 5STS) and postoperative outcomes (complications and LOS) in patients with gastrointestinal, abdominal and pelvic cancers were included. Risk of bias was assessed using the Quality in Prognosis Studies (QUIPS) tool. Where possible, summary odds ratios (OR) or mean differences (MD), and 95% confidence intervals (CI) were calculated using random-effect models., Results: Five studies (379 patients) were included, of which none utilized the 5STS. Overall, studies were rated as having low to moderate risk of bias. Higher preoperative performance on the 6MWT (≥400 m) was associated with low grade postoperative complications (OR = 0.38; 95% CI = 0.15-0.95) but was not associated with a shorter LOS (MD = 3.29; 95%CI = -1.07-7.66)., Conclusion: The available evidence suggests that in cancer patients, a higher preoperative functional capacity may be associated with reduced postoperative complications. Conversely, there is no significant association between preoperative function and LOS. Further high-quality studies are needed in this area, including studies involving 5STS., (© 2022 Royal Australasian College of Surgeons.)

Background: To determine the effectiveness of an individualised, daily targeted step count intervention and usual care compared with usual care alone on improving surgical and patient reported outcomes., Methods: The Fit-4-Home trial was a pragmatic, randomised controlled trial conducted from April 2019 to February 2021. Patients undergoing elective surgery for liver, stomach or pancreatic cancer in two Australian hospitals were recruited. Participants were randomly allocated to receive an individualised, targeted step count intervention and usual care (intervention) or usual care alone (control). A wearable activity tracker was provided to the intervention group to monitor their daily step count target. Primary outcome was the length of stay in the gastrointestinal ward. Secondary outcomes included postoperative complication rates, discharge destination, quality of life, physical activity, pain, fatigue, distress and hospital re-admission within 30 days. Outcome measures were compared between groups using non-parametric statistics., Results: Of the 96 patients recruited, 47 were randomised to the intervention group and 49 were randomised to the control group. The median (interquartile) length of stay in the ward was 7 days (5.0-13.0) in the intervention group and 7 days (5.0- 12.0) in the control group (p = 0.330). Fatigue scores were worse in the intervention group when compared to control (p = 0.018). No other differences between groups were observed., Conclusions: An individualised, daily targeted step count intervention and usual care did not confer additional benefits in reducing the length of stay in the ward compared to usual care alone for patients undergoing gastrointestinal cancer surgery., Trial Registration: Registered with the Australia and New Zealand Clinical Trials Registry (ACTRN12619000194167)., (© 2021 Royal Australasian College of Surgeons.)

Background: Home parenteral nutrition (HPN) is the recommended treatment for patients with type III intestinal failure (IF). However, owing to IF's rarity, the economic cost of managing these patients is not well understood. These patients often develop complications resulting in readmissions, which in turn contribute to ongoing costs. This study aims to document the costs of type III IF within the hospital, from initial admission, including readmissions, and to compare incurred costs with current government reimbursement., Methods: A retrospective study design reviewed costs and reimbursement for 25 consecutive patients commencing HPN at a quaternary hospital (October 2011 to September 2017). Hospital admissions were separated into the initial admission and readmission(s) period. Healthcare use and cost data were collected using electronic medical records. Hospital reimbursement costs were retrieved from Sydney Local Health District's Targeted Activity and Reporting Systems. Patient demographics were tabulated, and healthcare use and cost data were compared using Wilcoxon signed rank tests., Results: The median cost of the initial hospital admission was substantially higher than the median reimbursement ($36,675; interquartile range [IQR], $23,196-$67,439 vs $19,247; IQR, $7485-$41,090; P < .001). Similar results were observed in the readmissions period, with median incurred costs of $13,898; (IQR, $11,151-$32,130) vs reimbursement of $8469 (IQR, $5625-$13,078) (P = .001)., Conclusion: Results indicate that type III IF patients have high inpatient costs, which substantially outweigh current reimbursement. Improved funding models are needed to ensure hospitals that accept the management challenge of type III IF patients are not unduly penalized., (© 2021 American Society for Parenteral and Enteral Nutrition.)

Objectives: To determine what constitutes a clear resection margin (R0) in patients with LRRC., Summary of Background Data: R0 is the most important predictor of survival in patients with LRRC. However, it is not clear what constitutes an R0. A 1-2 mm margin is often used to define R0 but this is based on primary rectal cancer studies. The same definition of R0 is likely inappropriate considering the anatomy and etiology of local recurrences., Methods: A prospective maintained database was reviewed. A R2 margin was defined as macroscopic residual disease. R1 was defined as a microscopically involved margin (0 mm margin) and R0 as at least a 0.1 mm margin. Associations between R status and local recurrence was explored using X2 test. Associations between margins and overall survival and local recurrence free survival were explored using Kaplan-Meier analysis., Results: There were 210 patients eligible for inclusion for analysis. Of these, 165 (78.6%), 35 (16.7%), and 10 (4.8%) patients had R0, R1, and R2 margins, respectively. Overall survival was significantly different between patients with R0 versus R1 margins but wider resection margins do not confer a survival benefit [57 months (95% confidence interval 38.5-75.5) vs 33 months (95% confidence interval 20.3-45.7), P = 0.03]. Local recurrence free survival was significantly different between patients with R0 versus R1 margins (2- and 5-year local recurrence free survivals of 53.5% and 20.4% vs 25.9% and 14.8%, respectively, P = 0.001 for both). Margins >0.5 mm were not predictive of local recurrence free survival., Conclusions: A microscopically clear resection margin is most important in predicting overall survival. Margins up to 0.5 mm offers a local recurrence benefit but does not confer survival benefit., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

Aim: To describe the long-term course of pain and fatigue in patients undergoing pelvic exenteration and to evaluate potential prognostic factors for these outcomes., Design: Prospective cohort study., Settings: Royal Prince Alfred Hospital, Sydney, Australia., Patients: Consecutive patients undergoing pelvic exenteration surgery between July 2008 and December 2017., Main Outcome Measures: Pain and fatigue scores collected via SF-36v2 Health surveys pre-operatively and at eight time-points post-operatively for a period of 5-years. The course of pain and fatigue were described according to the following prognostic factors; bone resection (yes/no), cancer type (primary/recurrent), margin status (R0/R1-2) and extent of exenteration (complete/partial)., Results: 345 of 459 eligible patients (75 %) consented to the study. The course of pain and fatigue over the 5 year follow-up was favourable. Patients undergoing pelvic exenteration with an R0 resection margin or without bone resection presented lower pain levels throughout the follow-up period. Bone resection, positive surgical margin (R1/R2) and type of cancer did not influence fatigue trajectories. Patients undergoing complete pelvic exenteration were more likely to report a higher level of pain and fatigue in the initial follow-up period, however this difference was not observed in the longer-term., Conclusions: Patients undergoing PE (Austin and Solomon, 2015) [1] can expect improvement but an incomplete recovery in the levels of pain and fatigue postoperatively over the 5-year follow-up period. Bone resection as part of exenteration demonstrated higher levels of pain and fatigue., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Aim: Postoperative functional outcomes following pelvic exenteration surgery for treatment of advanced or recurrent pelvic malignancies are poorly understood. The aim of this study was to determine the short-term functional outcomes following pelvic exenteration surgery using objective measures of physical function., Method: Patients undergoing pelvic exenteration surgery between January 2017 and May 2020 were recruited at a single quaternary referral hospital in Sydney, Australia. The primary measures were the 6-min walk test (6MWT) and the five times sit to stand (5STS) test. Data were collected at baseline (preoperatively), 10 days postoperatively and at discharge from hospital, and were analysed according to tumour type, extent of exenteration, sacrectomy, length of hospital stay, major nerve resection and postoperative complications., Results: The cohort of patients that participated in functional assessments consisted of 135 patients, with a median age of 61 years. Pelvic exenteration patients had a reduced 6MWT distance preoperatively compared to the general population (P < 0.001). Following surgery, we observed a further decrease in 6MWT distance (P < 0.001) and an increase in time to complete 5STS (P < 0.001) at postoperative day 10 compared to baseline, with a slight improvement at discharge. There were no differences in 6MWT and 5STS outcomes between patients based on comparisons of surgical and oncological factors., Conclusion: Pelvic exenteration patients are functionally impaired in the preoperative period compared to the general population. Surgery causes a further reduction in physical function in the short term; however, functional outcomes are not impacted by tumour type, extent of exenteration, sacrectomy or nerve resection., (© 2021 Association of Coloproctology of Great Britain and Ireland.)

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., (© 2021. Society of Surgical Oncology.)

Introduction: Reporting of pelvic exenteration specimens for locally recurrent rectal cancer (LRRC) can be challenging for structured pathological analysis and currently, there is a lack of specific guidelines. The aim of this study was to assess the quality of pathology reporting in a cohort of patients who underwent pelvic exenteration for LRRC in a high-volume tertiary unit., Materials and Methods: In a retrospective analysis of histopathology reports of consecutive patients who underwent pelvic exenteration for LRRC from 1996 to 2018, the quality of pathology reporting was assessed using the Structure Reporting Protocol for Colorectal Cancer. The primary endpoint was the completeness of pathology reporting, secondary endpoints were the association between the reporting style (narrative versus synoptic), reporting period (the first half versus the second half), as well as the activity of the pathologists with the completeness of pathology reporting., Results: 221 patients who underwent pelvic exenteration for LRRC were included into the study. There was a high variability in completeness of pathology reporting within the cohort, ranging from 9.5% to 100%. Notably, microscopic clearance was reported in only 92.4% of the reports. Overall, a significantly higher rate of completeness was observed in synoptic reports when compared to narrative reports and in more recent compared to earlier reports. There was no significant association between the activity of pathologists and the completeness of reporting., Conclusions: This study shows a significant variability in the quality of reporting in pelvic exenteration for LRRC. The use of synoptic reporting clearly resulted in more complete reports., Competing Interests: Declaration of competing interest None of the investigators have any conflicts of interest to disclose., (Copyright © 2021 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: Anastomotic leak (AL) is a devastating complication. Several new treatment options are available, endoluminal negative pressure therapy is one. The aims of this systematic review are; to report success rates and stoma closure rates following endoluminal negative pressure therapy in colorectal AL patients., Methods: A systematic review of MEDLINE, PubMed, Cochrane and Embase databases from inception to June 2018. Search limits were; English language, humans, sample >5 and >18 years. Search terms were Endospong* OR Endo-spong* OR Endo spong* OR Endoluminal negative pressure OR Endoluninal vac* OR Vacuum assisted OR negative pressure. Combined with colon OR rectum OR colorect* AND anastomotic leak OR leak*., Results: Twenty articles met inclusion criteria. There were 334 patients. Reported success rates ranged from 60% to 100%. However, success definition varied considerably. The most widely used definition was endoscopic assessment of residual cavity size, but this also varied from 0.5 cm to 3 cm. Stoma closure rates were only reported in 11 studies and ranged from 31% to 100%. Complication rates were reported in 13 studies (65%). The most common was on-going sepsis., Conclusions: Included studies suggest that 60-100% of ALs heal with endoluminal negative pressure therapy. However, results from this review need to be interpreted with caution because of the variable definition of success. A more objective assessment of success may be stoma closure but this is only reported in 60% of studies. Further studies are needed to assess the benefit of negative pressure therapy in anastomotic leaks., (© 2021 Royal Australasian College of Surgeons.)

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 < 0.001). Postoperative wound complications increased with repeat exenteration (6%, 17%, 33%; P = 0.003, respectively). Additionally, postoperative length of stay increased from 27 to 38 and 48 days, respectively (P = 0.004). Median survival from first exenteration was 4.75, 5.30 and 8.14 years respectively amongst first, second and third exenteration cohorts (P = 0.849). Median survival from the most recent exenteration was 4.75 years after a first exenteration, 2.02 years after a second exenteration and 1.45 years after a third exenteration (P = 0.0546)., Conclusion: This study demonstrates that repeat exenteration for recurrent pelvic malignancy is feasible but is associated with increased complication rates and length of admission and reduced likelihood of attaining R0 margin. Moreover, these data indicate that repeat exenteration does not afford a survival advantage compared with patients having a single exenteration. These data suggest that repeat exenteration for recurrent pelvic malignancy may be of questionable therapeutic value., (© 2020 The Association of Coloproctology of Great Britain and Ireland.)

Aim: Our aim was to identify whether personality traits and decision-making styles affect quality of life (QoL) outcomes and levels of psychological distress following pelvic exenteration (PE)., Method: Patients undergoing PE between 2008 and 2015 were identified from a prospectively maintained database at a single quaternary referral centre. Patients were invited to complete two validated questionnaires, with the Big Five inventory being used to assess personality traits and the Melbourne Decision Making Questionnaire to determine decision-making style. Data on QoL outcomes and distress from the prospectively established database were utilized. QoL with respect to both physical and mental health components was measured using Short Form 36 version 2 (SF-36v2) and the Functional Assessment of Cancer Therapy - Colorectal (FACT-C). Distress was measured using the Distress Thermometer. Postoperative pain scores were also measured using SF-36v2., Results: Of the 93 patients eligible for participation, 42 returned the study questionnaire. On multivariate analysis, neuroticism was the most significant predictor of poorer QoL and increased levels of distress, consistent across all of the measures utilized and at the different time points used. Other personality traits showed an isolated statistically significant impact upon QoL. There were no significant findings with respect to decision-making style. Apart from neuroticism, the most significant predictor of QoL was the number of major complications for the patient., Conclusion: Patients demonstrating neurotic personality traits show poorer QoL outcomes and higher levels of distress following PE. Identification of these patients would allow targeted pre- and postoperative intervention to improve outcomes following PE., (© 2020 The Association of Coloproctology of Great Britain and Ireland.)

There have been significant developments in the management of advanced and recurrent colorectal cancer in recent decades. 70% of primary colorectal tumours arise in the colon and for patients with stage I-III disease, the standard of care is surgical resection followed by adjuvant therapy where appropriate. Locoregional recurrence (LR) occurs in 4-11.5% of patients following treatment of primary colon cancer with curative intent, and can be categorised as peri-anastomotic, mesenteric/paracolic (nodal), retroperitoneal and peritoneal. Of these, peritoneal recurrence is usually recognised as the most challenging type of recurrence to manage. Patients with isolated peri-anastomotic or limited nodal recurrence in the mesentery or retroperitoneum may be curable by radical salvage surgery, which often requires en bloc multi-visceral resection, while patients with low volume peritoneal metastases may be candidates for cytoreductive surgery with hyperthermic intraperitoneal chemotherapy. Ensuring complete resection along embryonic mesocolic planes or en bloc resection of contiguously involved structures are best strategies to reduce the likelihood of local recurrence through a R1 resection margin. The role of complete mesocolic excision (CME) with high vascular ligation has been demonstrated to increase nodal yield and improve overall survival although this is more contentious. In patients with T4a disease and serosal surface involvement, peritoneal recurrence represents the greatest threat. Efforts for early diagnosis of peritoneal recurrence in these patients or prophylactic treatment, while intuitive have not demonstrated the survival benefit that would be expected. Other than locoregional recurrence (LR), systemic recurrence may occur in up to 50% of patients who have undergone curative resection for colorectal cancer. In keeping with portal venous outflow, the most common site of systemic recurrence is the liver. Although previously thought to be a fatal condition, liver resection is now the standard of care where liver metastases can be completely resected with clear margins plus leaving an adequate liver remnant with intact vascular inflow, outflow and biliary drainage. This can usually be achieved in 26-45% of patients presenting with liver metastases. Liver surgeons at the forefront of liver resection have also developed techniques to induce liver hypertrophy so as to improve likelihood of resectability. Even where patients have non-resectable disease, ablative techniques have become increasingly common. Naturally, none of these would be possible without the advent of improved chemotherapeutic and biological options in the field of medical oncology. Pulmonary metastasectomy with curative intent may be possible in a small number (10%) of patients with lung metastases, which is associated with an overall survival of up to 40%. Unlike liver metastases, proportionally less patients with pulmonary metastases will be resectable. For these patients, several ablative options are available. For all patients with recurrent colon cancer, patient selection for radical salvage surgery and decisions surrounding treatment strategy (including use of systemic therapy or ablative procedures) should take place in a multidisciplinary team setting., Competing Interests: Conflicts of Interest: Both authors have completed the ICMJE uniform disclosure form (Available online: http://dx.doi.org/10.21037/jgo-2019-ccm-09).

Aim: The aim was to compare postoperative quality of life (QOL) between patients undergoing pelvic exenteration (PE) and pelvic exenteration with sacrectomy (PES), and to investigate the influence of high (L5-S2) vs low (≤ S3) sacrectomy on QOL and functional outcomes., Method: Patients undergoing en bloc sacrectomy as part of a PE and PE alone from 2008 to 2015 were identified from a prospectively maintained database. QOL and functional outcomes were assessed using the 36-Item Short Form Survey, the European Organization for Research and Treatment of Cancer Colorectal Cancer questionnaire and Quality of Life questionnaire, the Revised Musculoskeletal Tumour Scale, the Lower Extremity Functional Scale, the Sexual Health Inventory for Men and the Female Sexual Function Index., Results: Of the 344 patients identified, data were available for 116 patients who underwent PE alone and 140 patients who underwent PES. PES patients had significantly poorer physical component scores (P < 0.001) but not mental component scores (P = 0.17). Of the 140 PES patients, 55 were eligible and were invited to participate in a second functional survey, with 30 patients returning the study questionnaire. High sacrectomy patients, compared with low sacrectomy, had significantly worse lower limb motor function (P = 0.03) and poorer physical (P = 0.001) and mental health component scores (P = 0.02). No differences were found in sexual, bladder and bowel function between high and low sacrectomy patients., Conclusions: Patients undergoing PES had worse physical component scores compared with PE alone, whereas high sacrectomy patients had significantly worse lower limb motor function and physical and mental component scores but comparable bowel, bladder and sexual functional outcomes compared with low sacrectomy patients., (Colorectal Disease © 2019 The Association of Coloproctology of Great Britain and Ireland.)

Background: 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., Methods: 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., Results: 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., Conclusion: 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., (© 2019 BJS Society Ltd Published by John Wiley & Sons Ltd.)

Aim: Low anterior resection syndrome (LARS) can affect up to 70% of all patients with rectal cancer. In the last two decades, sacral nerve stimulation (SNS) has emerged as an effective treatment for faecal incontinence. There is some encouraging literature on the use of SNS in patients with LARS. The purpose of this review is to provide an up to date review on the utility of SNS on LARS., Method: A literature search was conducted using the MEDLINE, Embase and PubMed databases (January 1981-March 2019). Studies identified were appraised with standard selection criteria. Data points were extracted, and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses., Results: Ten studies met the inclusion criteria and were included in this study. All studies used the Cleveland Clinic Incontinence Score (CCIS), whereas the low anterior resection syndrome score (LARS score) was used in three studies. Overall median improvement in the scoring system was 67.0% (range 35.5%-88.2%) after SNS implantation. There was a significant reduction in CCIS after SNS implantation (mean difference 11.23, 95% confidence interval 9.38-13.07, Z = 11.90, P < 0.00001). The LARS score was also significantly reduced after using SNS in patients with LARS (mean difference 17.87, 95% confidence interval 10.15-25.59, Z = 4.54, P < 0.00001)., Conclusion: Use of SNS may provide symptomatic benefits for patients with LARS refractory to medical therapy. However, the current level of evidence remains limited. A large multicentre study of SNS for LARS using the validated LARS score is warranted. In addition, the cost-effectiveness of SNS for patients with LARS needs further exploration., (Colorectal Disease © 2019 The Association of Coloproctology of Great Britain and Ireland.)

Background: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is an accepted therapeutic approach in selected patients with peritoneal malignancy. The aim of this study was to describe early outcomes in the first 50 patients managed with CRS and HIPEC in a newly established peritoneal malignancy centre in Sydney, Australia, under the guidance of an experienced peritoneal malignancy mentor., Methods: This is a retrospective review of a prospective maintained database of early outcomes in the first 50 patients who underwent CRS and HIPEC between April 2017 and April 2018 at a newly established peritoneal malignancy centre. Type of primary, surgery time, length of hospital stay, blood loss, peritoneal carcinomatosis index, completeness of surgery, complications, recurrence rate and 30-day mortality were reviewed., Results: A total of 135 patients were referred and reviewed at the multidisciplinary team meeting with 50 (26 male) patients undergoing CRS and HIPEC. Of these 50 patients, 47 (94%) underwent complete cytoreduction while three (6%) had maximal tumour debulking surgery. Tumour pathology was of appendix origin (44%) and colorectal peritoneal metastases (44%). Median surgical time was 7.4 h (interquartile range 5.7-10.0). Median length of hospital stay was 13 days (interquartile range 9.7-19.0). Six (12%) patients experienced a grade III or IV Clavien-Dindo complication. There was no 30-day mortality., Conclusion: This study reports the successful establishment of a peritoneal malignancy centre under the guidance of an experienced peritoneal malignancy mentor. The short-term surgical outcomes observed in the first 50 cases are promising and comparable to other more experienced centres., (© 2019 Royal Australasian College of Surgeons.)

Background: Pelvic exenteration (PE) provides a potentially curative option for advanced or recurrent malignancy confined to the pelvis. A clear (R0) resection margin is the strongest prognostic factor predicting long-term survival, driving most technical advances in PE surgery. The aim of this cohort study was to describe changing trends in extent of resection, postoperative complications, mortality and overall survival after PE surgery., Methods: Consecutive patients who underwent PE for advanced or recurrent pelvic malignancy at a single institution in Sydney, Australia, were identified. The cohort was divided into three groups based on time periods reflecting annual surgical volume: 1994-2006 (20 or fewer procedures per year), 2007-2013 (21-50 procedures per year) and 2014-2017 (over 50 procedures per year). Primary outcomes were extent of resection, postoperative complications, 60-day mortality and 3-year overall survival. Secondary outcomes were patient characteristics, receipt of neoadjuvant therapy and duration of hospital stay., Results: There were increases over time in rates of lateral and posterior compartment resections (P < 0·001), and bony pelvis (P = 0·002) and neurovascular (P < 0·001) excision. For patients undergoing reconstruction, the proportion receiving vertical rectus abdominus myocutaneous flaps increased significantly (P = 0·005). Rates of wound infection, dehiscence, and abdominal and pelvic collections increased over the study interval. Short-term mortality decreased, and 1- and 3-year survival rates improved., Conclusion: Technical and surgical advancements have led to more complex PE resections, with R0 and mortality rates improving with higher annual volume. There were associated increases in intraoperative blood loss and postoperative morbidity., (© 2019 BJS Society Ltd Published by John Wiley & Sons Ltd.)
