Background: Haematochezia or per rectal (PR) bleeding is the most common presentation of lower gastrointestinal bleeding. This study analyses the hospital resources used in the management of patients with PR bleeding. Methods: A retrospective analysis was performed on patients who presented with PR bleeding from June 2012 to December 2013 to a single tertiary centre in Sydney, Australia. Age, gender, comorbidities, use of antiplatelet or anticoagulant medications, vital signs, and haematological data were recorded. The objective factors available on initial patient assessment were analysed for their relationship with the following outcomes: use of computed tomography mesenteric angiogram, formal angiography and embolization, transfusion of blood products, endoscopy, operative management and length of stay. Results: There were 523 confirmed presentations of PR bleeding. Four hundred and fiftytwo of these presented directly to emergency department, while 71 were referred from another hospital. One in five patients had blood transfusion (19%), 13% had computed tomography mesenteric angiogram, 4% had embolization and 13% underwent diagnostic and/or therapeutic colonoscopy. Patients referred from other facilities were more comorbid (55% versus 30%), more likely to be on antiplatelet or anticoagulant (69% versus 33%) with a higher rate of embolization (28% versus 4%), more packed cell transfusions (2.1 versus 0.7 units) and longer length of stay (7.9 versus 5.7 days) but mortality was the same (1%). Conclusions: The management of patients with PR bleeding is resource intensive. Better identification and allocation of resources in patients who present with PR bleeding may lead to better efficiency in managing this growing clinical problem.
Background While socioeconomic deprivation has been shown to affect survival in colorectal cancer, other factors such as global region of birth and ethnicity also exert an effect. We wished to ascertain the influence of socioeconomic deprivation on stage of presentation and cancer survival in an ethnically diverse Australian population. Methods Cases from a database of resections in Western Sydney (n = 1596) were stratified into cohorts of socioeconomic quintiles. Univariate analysis was used to compare demographics, AJCC stage and histopathological details between the least and most socioeconomically deprived groups. Kaplan–Meier analysis and log‐rank testing were used to compare cancer‐specific and all‐cause 5‐year survival between the most deprived quintile and all others, after case–control matching for age and overseas birth. Results A total of 322 (20.2%) patients from the most socioeconomically deprived centile, and 275 (17.2%) from the least were compared. The most deprived were significantly more likely to be aged under 70 (54.1% vs. 44.4%, p = 0.019), born overseas (54.3% vs. 38.6%, p = 0.003), present with stage III disease (37.4% vs. 26.7%, p = 0.005), perforated (12.5% vs. 5.3%, p = 0.005) or circumferential tumours (37% vs. 24.3%, p = 0.043). There was no significant difference in proportions presenting with metastatic disease, or 5‐year survival between the most deprived quintile and all others after correction for age and foreign birth. Conclusions Socioeconomic deprivation is associated with unfavourable colorectal cancer presentation stage but not poorer 5‐year survival in our Western Sydney population. The reasons for this are unclear and demand further attention.
Background: Flexible systems in robotic transanal surgery (RTA) are a proposed solution to the challenges of transanal minimally invasive surgery (TAMIS). RTA was performed with the Medrobotics Flex ® Robotics System to determine its safety and feasibility.Methods: Medrobotics Flex ® Robotics System was used for transanal resection of benign rectal polyps by a single surgeon in a tertiary centre, and cases retrospectively reviewed.Results: Five patients underwent flexible RTA, average age was 67 years. Polyps were between 5 and 12 o'clock, mean distance of 8.3 cm from the anal verge.Average operating time was 143 min. There was no peri-operative or 30-day morbidity or mortality. Histopathology included tubulovillous adenoma (TVA), and one hyperplastic polyp, all were clear of the surgical margin. Conclusion:This is the first case series using Medrobotics Flex ® Robotics System for RTA in a tertiary Australian public hospital. Flexible RTA is safe and feasible for the resection of benign rectal polyps.
Purpose: Enhanced Recovery After Surgery (ERAS) has become standard of care in colorectal surgery. However, there is not a universally accepted colorectal ERAS protocol and significant variations in care exist between institutions. The aim of this study was to examine the impact of variations in ERAS interventions and complications on length of stay (LOS).Methods: This study was a single-center review of the first 200 consecutive patients recruited into our prospectively collected ERAS database. The primary outcome of this study was to examine the rate of compliance to ERAS interventions and the impact of these interventions on LOS. The secondary outcome was to assess the impact of complications (anastomotic leak, ileus, and surgical site infections) on LOS. ERAS interventions, rate of adherence, LOS, readmissions, morbidity, and mortality were recorded, and statistical analysis was performed.Results: ERAS variations and complications significantly influenced patient LOS on both univariate and multivariate analysis. ERAS interventions identified as the most important strategies in reducing LOS included laparoscopic surgery, mobilization twice daily postoperative day (POD) 0 to 1, discontinuation of intravenous fluids on POD 0 to 1, upgrading to solid diet by POD 0 to 2, removal of indwelling catheter by POD 0 to 2, avoiding nasogastric tube reinsertion and removing drains early. Both major and minor complications increased LOS. Anastomotic leak and ileus were associated with the greatest increase in LOS.Conclusion: Seven high-yield ERAS interventions reduced LOS. Major and minor complications increased LOS. Reducing variations in care and complications can improve outcomes following colorectal surgery.
Background Positive circumferential resections are associated with local disease recurrence and reduced survival in rectal cancer. We studied a cohort of consecutive rectal cancer resections to assess for clinicopathological differences and survival in patients with positive and negative circumferential margins. Methods Rectal cancers were identified from a retrospective histopathology database of colorectal resections performed at five western Sydney hospitals from 2010 to 2016. Univariate and multivariate analysis with binary logistic regression were performed on histopathology data matched with survival times from the New South Wales Registry of Births Deaths and Marriages. Results A total of 502 rectal cancer patients were identified including 66 (13.1%) with involved circumferential margins. Patients with positive and negative circumferential margins had a similar distribution of age, gender and use of neoadjuvant radiotherapy. Tumours with involved circumferential margin comprised 98.5% T3 and T4 disease of which 51.5% received neoadjuvant radiotherapy. These were significantly associated with metastatic disease, increasing tumour size, circumferential and perforated tumours on univariate analysis. Multivariate analysis identified abdomino‐perineal resection (odds ratio (OR) 3.35; P = 0.003), en‐bloc multivisceral resection (OR 2.56; P = 0.032), T4 stage (OR 6.99; P < 0.001), perineural (OR 5.61; P < 0.001) and vascular invasion (OR 2.46; P = 0.022) as independent risk factors. Five‐year survival was significantly worse for patients with involved circumferential margins (26% versus 69%; P < 0.001). Conclusion Circumferential margin status reflects not only technical success but also aggressive disease phenotypes which require adjuvant therapy. Further work is needed to determine whether omission of radiotherapy has had an effect on long‐term outcomes in some of our at‐risk patients.
