Abstract

BACKGROUND: The multidisciplinary perioperative and anaesthetic management of patients undergoing pelvic exenteration is essential for good surgical outcomes. No clear guidelines have been established, and there is wide variation in clinical practice internationally. This consensus statement consolidates clinical experience and best practice collectively, and systematically addresses key domains in the perioperative and anaesthetic management. METHODS: The modified Delphi methodology was used to achieve consensus from the PelvEx Collaborative. The process included one round of online questionnaire involving controlled feedback and structured participant response, two rounds of editing, and one round of web-based voting. It was held from December 2019 to February 2020. Consensus was defined as more than 80 per cent agreement, whereas less than 80 per cent agreement indicated low consensus. RESULTS: The final consensus document contained 47 voted statements, across six key domains of perioperative and anaesthetic management in pelvic exenteration, comprising preoperative assessment and preparation, anaesthetic considerations, perioperative management, anticipating possible massive haemorrhage, stress response and postoperative critical care, and pain management. Consensus recommendations were developed, based on consensus agreement achieved on 34 statements. CONCLUSION: The perioperative and anaesthetic management of patients undergoing pelvic exenteration is best accomplished by a dedicated multidisciplinary team with relevant domain expertise in the setting of a specialized tertiary unit. This consensus statement has addressed key domains within the framework of current perioperative and anaesthetic management among patients undergoing pelvic exenteration, with an international perspective, to guide clinical practice, and has outlined areas for future clinical research.

Abstract

Item does not contain fulltext OBJECTIVE: To determine factors associated with outcomes following pelvic exenteration for advanced nonrectal pelvic malignancy. BACKGROUND: The PelvEx Collaborative provides large volume data from specialist centers to ascertain factors associated with improved outcomes. METHODS: Consecutive patients who underwent pelvic exenteration for nonrectal pelvic malignancy between 2006 and 2017 were identified from 22 tertiary centers. Patient demographics, neoadjuvant therapy, histopathological assessment, length of stay, 30-day major complication/mortality rate were recorded.The primary endpoints were factors associated with survival. The secondary endpoints included the difference in margin rates across the cohorts, impact of neoadjuvant treatment on survival, associated morbidity, and mortality. RESULTS: One thousand two hundred ninety-three patients were identified. 40.4% (n = 523) had gynecological malignancies (endometrial, ovarian, cervical, and vaginal), 35.7% (n = 462) urological (bladder), 18.1% (n = 234) anal, and 5.7% had sarcoma (n = 74).The median age across the cohort was 63 years (range, 23-85). The median 30-day mortality rate was 1.7%, with the highest rates occurring following exenteration for recurrent sarcoma or locally advanced cervical cancer (3.3% each). The median length of hospital stay was 17.5 days. 34.5% of patients experienced a major complication, with highest rate occurring in those having salvage surgery for anal cancer.Multivariable analysis showed R0 resection was the main factor associated with long-term survival. The 3-year overall-survival rate for R0 resection was 48% for endometrial malignancy, 40.6% for ovarian, 49.4% for cervical, 43.8% for vaginal, 59% for bladder, 48.3% for anal, and 48.1% for sarcoma. CONCLUSION: Pelvic exenteration remains an important treatment in selected patients with advanced or recurrent nonrectal pelvic malignancy. The range in 3-year overall survival following R0 resection (40%-59%) reflects the diversity of tumor types.

Abstract

AIM: At presentation, 15-20% of patients with rectal cancer already have synchronous liver metastases. The aim of this study was to determine the surgical and survival outcomes in patients with advanced rectal cancer who underwent combined pelvic exenteration and liver (oligometastatic) resection. METHOD: Data from 20 international institutions that performed simultaneous pelvic exenteration and liver resection between 2007 and 2017 were accumulated. Primarily, we examined perioperative outcomes, morbidity and mortality. We also assessed the impact that margin status had on survival. RESULTS: Of 128 patients, 72 (56.2%) were men with a median age of 60 years [interquartile range (IQR) 15 years]. The median size of the liver oligometastatic deposits was 2 cm (IQR 1.8 cm). The median duration of surgery was 406 min (IQR 240 min), with a median blood loss of 1090 ml (IQR 2010 ml). A negative resection margin (R0 resection) was achieved in 73.5% of pelvic exenterations and 66.4% of liver resections. The 30-day mortality rate was 1.6%, and 32% of patients had a major postoperative complication. The 5-year overall survival for patients in whom an R0 resection of both primary and metastatic disease was achieved was 54.6% compared with 20% for those with an R1/R2 resection (P = 0.006). CONCLUSION: Simultaneous pelvic exenteration and liver resection is feasible, with acceptable morbidity and mortality. Simultaneous resection should only be performed where an R0 resection of both pelvic and hepatic disease is anticipated.

Abstract

AIM: We aim to compare machine learning with neural network performance in predicting R0 resection (R0), length of stay > 14 days (LOS), major complication rates at 30 days postoperatively (COMP) and survival greater than 1 year (SURV) for patients having pelvic exenteration for locally advanced and recurrent rectal cancer. METHOD: A deep learning computer was built and the programming environment was established. The PelvEx Collaborative database was used which contains anonymized data on patients who underwent pelvic exenteration for locally advanced or locally recurrent colorectal cancer between 2004 and 2014. Logistic regression, a support vector machine and an artificial neural network (ANN) were trained. Twenty per cent of the data were used as a test set for calculating prediction accuracy for R0, LOS, COMP and SURV. Model performance was measured by plotting receiver operating characteristic (ROC) curves and calculating the area under the ROC curve (AUROC). RESULTS: Machine learning models and ANNs were trained on 1147 cases. The AUROC for all outcome predictions ranged from 0.608 to 0.793 indicating modest to moderate predictive ability. The models performed best at predicting LOS > 14 days with an AUROC of 0.793 using preoperative and operative data. Visualized logistic regression model weights indicate a varying impact of variables on the outcome in question. CONCLUSION: This paper highlights the potential for predictive modelling of large international databases. Current data allow moderate predictive ability of both complex ANNs and more classic methods.

Abstract

Surgery remains the cornerstone of rectal cancer treatment. However, there is significant morbidity and mortality associated with pelvic surgery, and the past decade has illustrated that a cohort of rectal cancer patients sustain a remission of local disease with chemoradiation alone. Thus, questions remain regarding the optimal management for rectal cancer; namely, accurately identifying patients who have a complete pathologic response and determining the oncologic safety of the observational approach for this patient group. This review aims to summarize the current evidence to provide an overview to the 'watch and wait' approach in rectal cancer patients with a complete response to neoadjuvant chemoradiation therapy.

Abstract

Aim: At presentation, 15–20% of patients with rectal cancer already have synchronous liver metastases. The aim of this study was to determine the surgical and survival outcomes in patients with advanced rectal cancer who underwent combined pelvic exenteration and liver (oligometastatic) resection. Method: Data from 20 international institutions that performed simultaneous pelvic exenteration and liver resection between 2007 and 2017 were accumulated. Primarily, we examined perioperative outcomes, morbidity and mortality. We also assessed the impact that margin status had on survival. Results: Of 128 patients, 72 (56.2%) were men with a median age of 60 years [interquartile range (IQR) 15 years]. The median size of the liver oligometastatic deposits was 2 cm (IQR 1.8 cm). The median duration of surgery was 406 min (IQR 240 min), with a median blood loss of 1090 ml (IQR 2010 ml). A negative resection margin (R0 resection) was achieved in 73.5% of pelvic exenterations and 66.4% of liver resections. The 30-day mortality rate was 1.6%, and 32% of patients had a major postoperative complication. The 5-year overall survival for patients in whom an R0 resection of both primary and metastatic disease was achieved was 54.6% compared with 20% for those with an R1/R2 resection (P = 0.006). Conclusion: Simultaneous pelvic exenteration and liver resection is feasible, with acceptable morbidity and mortality. Simultaneous resection should only be performed where an R0 resection of both pelvic and hepatic disease is anticipated.

Abstract

Item does not contain fulltext OBJECTIVE: Palliative pelvic exenteration (PPE) is a technically complex operation with high morbidity and mortality rates, considered in patients with limited life expectancy. There is little evidence to guide practice. We performed a systematic review to evaluate the impact of PPE on symptom relief and quality of life (QoL). METHODS: A systematic review was conducted according to the PRISMA guidelines using Ovid MEDLINE, EMBASe, and PubMed databases for studies reporting on outcomes of PPE for symptom relief or QoL. Descriptive statistics were used on pooled patient cohorts. RESULTS: Twenty-three historical cohorts and case series were included, comprising 509 patients. No comparative studies were found. Most malignancies were of colorectal, gynaecological and urological origin. Common indications for PPE were pain, symptomatic fistula, bleeding, malodour, obstruction and pelvic sepsis. The pooled median postoperative morbidity rate was 53.6% (13-100%), the median in-hospital mortality was 6.3% (0-66.7%), and median OS was 14 months (4-40 months). Some symptom relief was reported in a median of 79% (50-100%) of the patients, although the magnitude of effect was poorly measured. Data for QoL measures were inconclusive. Five studies discouraged performing PPE in any patient, while 18 studies concluded that the procedure can be considered in highly selected patients. CONCLUSION: Available evidence on PPE is of low-quality. Morbidity and mortality rates are high with a short median OS interval. While some symptom relief may be afforded by this procedure, evidence for improvement in QoL is limited. A highly selective individualised approach is required to optimise the risk:benefit equation.

Abstract

Contains fulltext : 215764.pdf (Publisher’s version ) (Open Access) Background: Pelvic exenteration for locally advanced rectal cancer (LARC) and locally recurrent rectal cancer (LRRC) is technically challenging but increasingly performed in specialist centres. The aim of this study was to compare outcomes of exenteration over time. Methods: This was a multicentre retrospective study of patients who underwent exenteration for LARC and LRRC between 2004 and 2015. Surgical outcomes, including rate of bone resection, flap reconstruction, margin status and transfusion rates, were examined. Outcomes between higher- and lower-volume centres were also evaluated. Results: Some 2472 patients underwent pelvic exenteration for LARC and LRRC across 26 institutions. For LARC, rates of bone resection or flap reconstruction increased from 2004 to 2015, from 3.5 to 12.8 per cent, and from 12.0 to 29.4 per cent respectively. Fewer units of intraoperative blood were transfused over this interval (median 4 to 2 units; P = 0.040). Subgroup analysis showed that bone resection and flap reconstruction rates increased in lower- and higher-volume centres. R0 resection rates significantly increased in low-volume centres but not in high-volume centres over time (low-volume: from 62.5 to 80.0 per cent, P = 0.001; high-volume: from 83.5 to 88.4 per cent, P = 0.660). For LRRC, no significant trends over time were observed for bone resection or flap reconstruction rates. The median number of units of intraoperative blood transfused decreased from 5 to 2.5 units (P < 0.001). R0 resection rates did not increase in either low-volume (from 51.7 to 60.4 per cent; P = 0.610) or higher-volume (from 48.6 to 65.5 per cent; P = 0.100) centres. No significant differences in length of hospital stay, 30-day complication, reintervention or mortality rates were observed over time. Conclusion: Radical resection, bone resection and flap reconstruction rates were performed more frequently over time, while transfusion requirements decreased.

Abstract

Background: Patients with inflammatory bowel disease (IBD) undergo surveillance for an increased risk of colorectal cancer. Advances in endoscopy have rendered most previously invisible dysplasia visible, leading to changes in guidelines around surveillance and management of dysplasia. This study aims to assess New Zealand endoscopists' (i) understanding of current guidelines, (ii) uptake of advanced techniques and (iii) management of dysplasia., Methods: A digital survey of New Zealand endoscopists was undertaken. Invitations were sent to members of New Zealand gastroenterology and surgical societies. Questions were asked regarding demographics, surveillance interval, risk stratification, endoscopic technique and dysplasia management., Results: Fifty of the 322 invitees completed the survey (15.5%). Over 80% used techniques meeting the guideline recommendations. The majority (77%) of endoscopists take random biopsies in addition to targeted. Endoscopically resectable polypoid low-grade dysplasia was typically managed with surveillance (93%) but this dropped to less than half for high-grade dysplasia and less than a third for non-polypoid high-grade dysplasia (inconsistent with guidelines)., Conclusions: Current New Zealand endoscopists' practice appears to be aligned with international guidelines in terms of screening interval, risk stratification and technique. However, New Zealand endoscopists are less likely to offer a patient surveillance for endoscopically resectable dysplasia., Competing Interests: Nil.

Abstract

Background: Ulcerative colitis (UC) is a risk factor in developing colorectal cancer (CRC). Surveillance programmes aim to identify premalignant lesions to facilitate improved treatment outcomes. Recent studies have suggested that the risk of CRC in UC has decreased. This study aims to characterize the risk of CRC in UC in a population-based New Zealand cohort., Methods: All patients in the Canterbury Inflammatory Bowel Disease Study, a comprehensive population-based cohort, were reviewed and cases of dysplasia and CRC identified. Demographic data and risk factors were assessed and standardized incidence ratios (SIRs) calculated comparing with the national population., Results: A total of 518 UC cases were analysed (46.3% female). Median follow-up was 17.5 years (interquartile range 12.2-25.1 years). Neoplasia developed in 42 (8.1%) patients, 14 (2.7%) of whom had CRC. The mean age at CRC diagnosis was 63.3 years, and mean duration with UC before CRC 18.4 years (0-36.8 years). The total incidence rate was 1.35/1000 person-year duration (95% confidence interval 0.74-2.27). The age-adjusted SIR was 1.74 (95% confidence interval 1.03-2.93) compared to the New Zealand population. Risk factors for any dysplasia included disease extent and male gender., Conclusion: In this population-based cohort with long-term follow-up, the SIR of CRC in UC patients was significantly lower than the initial epidemiological studies although similar to more recent studies. This increased risk still justifies ongoing screening in the UC population., (© 2020 Royal Australasian College of Surgeons.)

Abstract

Background: Symptoms of bloating, discomfort and altered bowel function persist post-colonoscopy in up to 20% of patients. A previous randomized controlled trial of probiotics for post-colonoscopy symptoms has demonstrated a reduction in duration of pain with the use of probiotics. This was performed with air insufflation and the question was asked whether the effect would persist with the use of carbon dioxide to insufflate the colon., Methods: Eligible patients were recruited and randomized to receive either probiotic or placebo capsules post colonoscopy. A questionnaire was completed documenting the presence of pre-procedural and post-procedural symptoms for the following 2 weeks. The results were entered into a database and processed by an independent statistician. The primary outcome was mean pain score and incidence of bloating over the first 7 days and at 14 days post procedure. The secondary outcome was the time to return of normal bowel function., Results: Two hundred and forty participants were recruited and randomized (120 probiotic and 120 placebo). Data were available for 75 patients in the probiotic and 75 in the placebo group. There was no significant difference between groups in post-procedural discomfort, bloating nor time to return of normal bowel function. Subgroup analysis of the patients with preexisting symptoms showed a reduction in incidence of bloating with the use of probiotics., Conclusion: There may be a role for the use of probiotics in the subgroup of patients with preexisting symptoms; however, routine use of probiotics to ameliorate post-procedural symptoms of carbon dioxide insufflation colonoscopy cannot be advocated., (© 2018 Royal Australasian College of Surgeons.)

Abstract

Surgery remains the cornerstone of rectal cancer treatment. However, there is significant morbidity and mortality associated with pelvic surgery, and the past decade has illustrated that a cohort of rectal cancer patients sustain a remission of local disease with chemoradiation alone. Thus, questions remain regarding the optimal management for rectal cancer; namely, accurately identifying patients who have a complete pathologic response and determining the oncologic safety of the observational approach for this patient group. This review aims to summarize the current evidence to provide an overview to the 'watch and wait' approach in rectal cancer patients with a complete response to neoadjuvant chemoradiation therapy., (© 2018 Royal Australasian College of Surgeons.)

Abstract

Retrorectal tumors are rare tumors that require resection for symptoms, malignancy and potential malignant transformation. Traditional approaches have included laparotomy, perineal excision or a combination. Multiple minimally invasive techniques are available which have the potential to minimize morbidity and enhance recovery. We performed a systematic review of the literature to determine the feasibility and surgical outcomes of retrorectal tumors approached using minimally invasive surgical techniques. Publications in which adult patients (≥ 18 years) had a minimally invasive approach (laparoscopic or robotic) for resection of a primary retrorectal tumor were included. Data were collected on approach, preoperative investigation, size and sacral level of the tumor, operating time, length of stay, perioperative complications, margins and recurrence. Thirty-five articles which included a total of 82 patients met the inclusion criteria. The majority of patients were female (n = 65; 79.2%), with a mean age of 41.7 years (range 18-89 years). Seventy-three patients (89.0%) underwent laparoscopic or combined laparoscopic-perineal resection, and 9 (10.8%) had a robotic approach. The conversion rate was 5.5%. The overall 30-day morbidity rate was 15.7%, including 1 intraoperative rectal injury (1.2%). Ninety-five percent (n = 78) of the retrorectal tumors were benign. Median length of stay was 4 days for both laparoscopic and robotic groups, with ranges of 1-8 and 2-10 days, respectively. No tumor recurrence was noted during follow-up [median 28 months (range 5-71 months)]. A minimally invasive approach for the resection of retrorectal tumors is feasible in selected patients. Careful patient selection is necessary to avoid incomplete resection and higher morbidity than traditional approaches.
