RESUMEN
In a healthcare setting, a multitude of ethical and moral challenges are often present when patients and families direct uncivil behavior toward clinicians and staff. These negative interactions may elicit strong social and emotional reactions among staff, other patients, and visitors; and they may impede the normal functioning of an institution. Ethics Committees and Clinical Ethics Consultation Services (CECSs) can meaningfully contribute to organizational efforts to effectively manage incivility through two distinct, yet inter-related channels. First, given their responsibility to promote a humane, respectful, and professional climate, many CECSs and Ethics Committees may assist institutional leadership in evaluating and monitoring incivility policies and procedures. Second, when confronted with individual incidents of patient/family incivility, Ethics Consultants can and often do work with all stakeholders to address and mitigate potentially deleterious impacts. This manuscript presents an overview of the multifaceted ethical implications of incivility in the healthcare environment, discusses the inherent qualifications of Ethics Consultants for assisting in the management of incivility, and proposes specific mitigating actions within the purview of CECSs and Ethics Committees. We also invite healthcare organizations to harness the skills and reputation of their CECSs and Ethics Committees in confronting incivility through comprehensive policies, procedures, and training.

PURPOSE: Distant recurrence is a devastating occurrence after colorectal cancer resection. This study aimed to identify the risk factors for distant recurrence following surgery. METHODS: All consecutive colorectal cancer resections with curative intent were included from a prospectively maintained colorectal cancer database. The primary outcome was to identify predictive factors for distant recurrence of colorectal cancer. RESULTS: A total of 670 eligible cases were identified with 88 (13.1%) developing distant recurrence during the follow-up period. The median time to distant recurrence was 1.2 years with the most common sites of distant recurrence being the lung (44.3%) and liver (44.3%). Predictive factors for distant recurrence in colon cancer included a high tumor, nodal, and overall stage of the primary cancer (p < 0.001 for all). Surgical complications (p = 0.007), including anastomotic leak (p = 0.023), were associated with a higher risk of developing distant recurrence in rectal cancer patients. Independent variables associated with distant recurrence included tumor stage (OR 1.61, p = 0.011), nodal stage (OR 2.18, p < 0.001), and both KRAS (OR 11.04, p < 0.001) and MLH/PMS2 (OR 0.20, p = 0.035) genetic mutations. Among patients with distant recurrence, treatment with surgery conferred the best survival, with patients < 50 years of age having the best overall 5-year survival. CONCLUSION: Predictive factors for distant recurrence include advanced tumor and nodal stages, and the presence of KRAS and MLH/PSM2 mutations. Clinicians should be cognizant of these risk factors, and instate close surveillance plans for patients exhibiting these features.

Patients with cancer face many difficult decisions and encounter many clinical situations that undermine decisional capacity. For this reason, assessing decision-making capacity should be thought of at every medical encounter. The culmination of variable disease trajectories, following patients to the end of life, use of high-risk treatments, and other weighty personal decisions require attention to patients' ability to engage in decisions. Oncologists develop meaningful relationships with their patients. This familiarity may lead to forgoing the process of diligently assessing a patient's cognitive ability and/or decisional capacity when important decisions need to be made. While the process may feel like it takes place spontaneously, many subtle and overt details are involved with the decisions around cancer care that require pointed questioning and probing. Thus, there are many ways to fall short in determining decisional capacity. Clinicians are inconsistent in their decisional capacity determinations and generally assume more decisional capacity than the patient has. Consult and referral services such as ethics and psychiatry can help with treatment decisions and with assessing underlying psychosocial and psychiatric conditions. Decisional capacity may fluctuate and requires a variable amount of decisional ability depending on the clinical situation; hence, it is time-specific and decision-specific. This review is intended to provide a summary of key components of decisional capacity while highlighting areas in need of clinical refinement.

BACKGROUND: Colon cancer resection can be technically difficult in the obese (OB) population. Robotic surgery is a promising technique but its benefits remain uncertain in OB patients. The aim of this study is to compare OB versus non-obese (NOB) patients undergoing robotic colon surgery, as well as OB patients undergoing robotic versus open or laparoscopic colonic surgery. METHODS: A systematic review and meta-analysis was performed. Primary outcome measures included length of stay (LOS), surgical site infection (SSI) rate, complications, anastomotic leak and oncological outcomes. RESULTS: A total of eight studies were included, with five comparing OB and NOB patients undergoing robotic colon surgery included in meta-analysis. A total of 263 OB patients and 400 NOB patients formed the sample for meta-analysis. There was no significant difference between the two groups in operative time, conversion to open, LOS, lymph node yield, anastomotic leak and postoperative ileus. There was a trend towards a significant increase in overall complications and SSI in the OB group (32.3% OB versus 26.8% NOB for complications, 14.2% OB versus 9.9% NOB for SSI). The three included studies comparing surgical techniques were too heterogeneous to undergo meta-analysis. CONCLUSION: Robotic colon surgery is safe in obese patients, but high-quality prospective evidence is lacking. Future studies should report on oncological safety and the cost-effectiveness of adopting the robotic technique in these challenging patients.

BACKGROUND: This study aimed to characterise the outcomes associated with colorectal cancer (CRC), comparing young adults (<50 years), patients of screening age (50-79 years), and octogenarians (>80 years). METHODS: All consecutive CRC resections with curative intent were recruited into this study from a prospectively maintained CRC database at a tertiary academic centre. RESULTS: A total of 745 eligible cases were identified. Five-year survival in young adults was poorer than that of patients of screening age. Young adults had the highest incidence of rectal cancer resections, and presented with the most advanced tumour stages. Independent associations for poorer survival in young adults were increased nodal stage, the presence of distal metastases, and loss of MLH1/PMS2 staining on immunohistochemistry. Young adults had similar survival to octogenarians, when comparing patients treated with curative intent, regardless of oncological treatment.

Rectal cancer is a challenging disease process to manage, with a rising incidence in young adults. Several clinical advances have been made in the past decade with regards to optimal treatment strategies in early-stage (T1-2, node negative tumours) and locally advanced cancers (T3-4 and/or nodal positivity) utilizing a multimodal approach of surgery, neoadjuvant chemoradiotherapy, and adjuvant chemotherapy, all aiming to optimize oncological outcomes, while minimizing associated morbidity. This narrative review aimed to summarize trial level evidence apropos the management of early and locally advanced rectal cancer. All relevant prospective clinical trials were identified through a computer-assisted search of PubMed, EMBASE, Medline databases between 1990 and 30 June 2021. With regards to early rectal cancer, there is limited trial-level evidence in the literature. Total mesorectal excision (TME) is the current standard of care, but local excision could be considered in select patients with pT1 tumours, or patients with near or complete clinical response to neoadjuvant CRT. As for locally advanced rectal cancer, the current standard of care consists of long-course chemotheradiotherapy or short-course radiotherapy, followed by TME. However, the role of total neoadjuvant therapy is promising, with respect to both oncological outcomes, as well as in reducing toxicity. Both induction and consolidation chemotherapy treatment approaches have been described in literature, with encouraging early results. The optimal management of rectal cancer is constantly evolving. More research is needed to investigate the long-term oncological and functional outcomes following new multimodal therapies in the management of early-stage and locally advanced rectal cancer.

BACKGROUND: Small bowel obstruction (SBO) is a common general surgical presentation and there has been a shift towards non-operative management (NOM) for patients with previous abdominal surgery. Historically, exploratory surgery has been mandated for SBO in patients with a virgin abdomen. However, there is increasing evidence for NOM in this group of patients. METHODS: A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A search was undertaken between 1995 and 2020 on Ovid MEDLINE, EMBASE and PubMed. Primary outcome measures were success and failure rates, whereas secondary outcome measures were morbidity, mortality rates and identifying underlying aetiologies. RESULTS: Six observational studies were included, with 205 patients in the NOM and 211 patients in the operative group. There was a high success rate of 95.6% and low morbidity rate of 3.1% in the NOM group compared to 88.6% and 26% in the operative group, respectively. Both groups reported no mortalities. The most common aetiologies for SBO in a virgin abdomen were adhesions (63%), malignancy (11%), foreign body/bezoar (5%), internal hernia (4%) and volvulus (4%). CONCLUSION: NOM for SBO is a safe and feasible option for a select group of clinically stable patients with a virgin abdomen without features of closed-loop obstruction. Adhesions are the most common cause of SBO in this group of patients. Further large-scale prospective clinical studies with standardized NOM modality, homogenous clinical resolution indicators and long-term follow-up data are warranted to allow for quantitative analysis to reinforce this evidence.

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic has raised a variety of ethical dilemmas for health care providers. Limited data are available on how a patient's concomitant cancer diagnosis affected ethical concerns raised during the early stages of the pandemic. METHODS: We performed a retrospective review of all COVID-related ethics consultations registered in a prospectively collected ethics database at a tertiary cancer center between March 14, 2020, and April 28, 2020. Primary and secondary ethical issues, as well as important contextual factors, were identified. RESULTS: Twenty-six clinical ethics consultations were performed on 24 patients with cancer (58.3% male; median age, 65.5 years). The most common primary ethical issues were code status (n = 11), obligation to provide nonbeneficial treatment (n = 3), patient autonomy (n = 3), resource allocation (n = 3), and delivery of care wherein the risk to staff might outweigh the potential benefit to the patient (n = 3). An additional nine consultations raised concerns about staff safety in the context of likely nonbeneficial treatment as a secondary issue. Unique contextual issues identified included concerns about public safety for patients requesting discharge against medical advice (n = 3) and difficulties around decision making, especially with regard to code status because of an inability to reach surrogates (n = 3). CONCLUSION: During the early pandemic, the care of patients with cancer and COVID-19 spurred a number of ethics consultations, which were largely focused on code status. Most cases also raised concerns about staff safety in the context of limited benefit to patients, a highly unusual scenario at our institution that may have been triggered by critical supply shortages.

BACKGROUND: Anal intraepithelial neoplasia (AIN) is dysplasia in the epithelium of the anus and is a pre-malignant condition associated with a low rate of progression to invasive squamous cell carcinoma (SCC). The natural history of progression for AIN to anal SCC is poorly defined. This study aims to review our experience with AIN and investigate the natural history of progression. METHODS: Data on all patients with AIN from January 2005 to December 2015 were retrospectively reviewed. Three separate databases were searched - Colorectal, Radiation Oncology and Infectious Diseases. All databases were cross-referred to obtain a complete but non-duplicated data set. Electronic charts were reviewed to obtain clinical information. RESULTS: Twenty-eight patients were identified with AIN of various grades. There were 25 males, three females. Twenty of the male patients were human immunodeficiency virus (HIV) positive. Mean length of follow up was 56 months. Complete regression of AIN to normal was noted in 13 patients (46%). Four patients had persisting AIN III with no evidence of regression or malignant transformation. Nine patients with pre-existing AIN developed SCC (32%). Seven were positive for HIV infection (all males). Median time to progression was 36 months. None of the patients demonstrated clear linear pattern of progression of AIN to SCC. CONCLUSION: High grade AIN may progress to anal SCC and surveillance is indicated. The exact natural history of progression for AIN is difficult to predict. There is no linear progression over time evident. HIV patients with AIN are at higher risk of developing SCC.

BACKGROUND: Colorectal cancer resection in the obese (OB) patients can be technically challenging. With the increasing adoption of laparoscopic surgery, the benefits remain uncertain. Hence, the aim of this study is to assess the short- and long-term outcomes of laparoscopic compared to open colorectal cancer resection in the OB patients. METHODS: A systematic review and meta-analysis was performed according to the PRISMA guidelines. The outcome measures were 5-year disease-free survival, overall survival, circumferential resection margin and local and distant recurrence. RESULTS: A total of 20 studies were included, with a total number of 6779 participants, of whom 1785 (26.3%) were OB and 4994 (73.7%) were non-obese (NOB) participants. The OB patients had higher R1 resection (OB 6.9% versus NOB 3.1%; P = 0.011) and lower mean number of lymph nodes harvested, with standard mean difference of -0.29; P = 0.023, favouring the NOB patients. However, there was no statistical difference for local (OB 2.8% versus NOB 3.4%) or distant recurrence (OB 12.9% versus NOB 15.2%) rate between the two cohorts. There was no difference in 5-year disease-free survival (OB 81% versus NOB 77.4%; odds ratio 1.25, P = 0.215) and overall survival (OB 89.4% versus NOB 87.9%; odds ratio 1.16, P = 0.572). Lastly, the OB group had higher mean total blood loss, total operative time and length of hospital stay when compared to NOB patients. CONCLUSION: From a pooled non-randomized study, laparoscopic colorectal cancer resection is safe in OB patients with equivalent long-term outcomes compared to NOB patients. However, there is a higher morbidity rate with an increased demand on hospital resources for the OB cohort.

BACKGROUND: Enterocutaneous fistulas (ECFs) are complex and can result in significant morbidity and mortality. The study aimed to evaluate ECF outcomes in a single tertiary hospital. METHODS: A retrospective study of all patients treated with ECF between the period of January 2009 and June 2014 was conducted. Baseline demographic data assessed included the primary aetiology of the fistula, site of the fistula and output of the fistula. Outcomes measures assessed included re-fistulation rate, return to theatre, wound complications, fistula closure rate and death over the study period. RESULTS: A total of 16 patients with ECF were recorded within the study period. Mean age of the patient cohort was 55.8 ± 11.8 years with a female predominance (11 females, 5 males). Primary aetiology were Crohn's disease (31%), post intra-abdominal surgery not related to bowel neoplasia (50%) and post intra-abdominal surgery related to bowel neoplasia (19%). Majority of the fistulas developed from the small bowel (75%) and had low output (63%). Operative intervention was required in 81% of patients with an overall closure rate of 100%. Median operations required for successful closure was 1.15 operations. Mean duration between index operation and curative operation was 8 ± 12.7 months. CONCLUSION: Appropriate bundle of care (perioperative care, surgical timing and surgical technique) can produce excellent results in patients with ECF.

BACKGROUND/OBJECTIVES: Adjuvant chemotherapy for Stage II colon cancer offers a small (2-3%) overall survival benefit and is not universally recommended. Mismatch repair deficiency (dMMR) confers an improved prognosis identifying patients unlikely to benefit from adjuvant chemotherapy. The aim of this study was to investigate the use of dMMR immunohistochemistry in two major cancer treatment centres. METHODS: Prospective data were collected on all patients with resected Stage II colon cancer between 2010 and 2015 across two large Australian hospitals. Data collected included patient demographics, tumour histology, dMMR immunohistochemistry, chemotherapy use, and outcomes. RESULTS: All 355 patients (56.1% female, median age 81) with resected Stage 2 Colon cancer entered on to the surgical database were included in this analysis. MMR testing was performed on 167 patient samples (47%), most occurred post-2013 (73.1% vs. 26.9% patients). dMMR rates were 34.1%. 25 (7.3%) received adjuvant chemotherapy, with no patient >80 years receiving treatment. Presence of ≥2 high-risk feature increased the likelihood of adjuvant chemotherapy. Only 3.6% dMMR patients received chemotherapy; both were young with high-risk features. 27/288 (7.6%) patients (with follow up) relapsed, with 7 disease-free post-resection of metastatic disease, 9 are alive with metastatic disease, and 11 deceased. CONCLUSIONS: Unlike clinical trial populations, Stage 2 colon cancer patients are often elderly, have high rates of dMMR tumours, are rarely offered chemotherapy, yet still have excellent outcomes. dMMR immunohistochemistry is being increasingly used to identify Stage 2 patients who do not require chemotherapy.

BACKGROUND: Diverting loop ileostomy (DLI) is used following low anterior resections (LAR) or ultra-low anterior resections (ULAR) to reduce anastomotic leak (AL). Preoperative mechanical bowel preparation (MBP) is traditionally used with DLI. However, clearance of the left colon can be achieved with a fleet enema without the physiological compromise of MBP. We aimed to assess colonic transit following DLI in this context. METHODS: A prospective, observational study was performed with patients with rectal cancer undergoing LAR or ULAR in a tertiary colorectal unit with preoperative fleet enema. Radiopaque markers were inserted into the caecum following rectal resection and formation of a DLI with placement confirmed by image intensifier and endoscopy. X-rays were performed at days 1, 3, 5 and 14 post-operation with data collected prospectively. RESULTS: Ten patients (mean age 57, nine males) were enrolled. Mean time to functioning stoma was 1.9 days (range 1-3). There was no movement in the majority of markers in all patients at Day 5 post-operation. In all seven patients with Day 14 X-rays, the majority of markers remained in the right colon. Two patients had delayed AL, with markers found within the pelvis in both of these patients. CONCLUSIONS: This is the first study to assess colonic transit following DLI using fleet enema only, with results suggesting colonic motility is abolished in this setting. The use of a fleet enema without MBP may be sufficient prior to rectal resection surgery when DLI is employed. AL may actually increase colonic transit. Further research is warranted.

BACKGROUND: Botulinum toxin (Botox) injection for chronic anal fissure (CAF) is commonly performed, yet there remains no consensus on optimal dosage or frequency of injections required to achieve complete resolution of anal fissure. The aim of this study was to determine the effectiveness of Botox and side-effect profile in the management of CAF. METHODS: A retrospective clinical study of patients between 2010 and 2014 who underwent a Botox injection for CAF at a tertiary centre was performed. The effectiveness of Botox was measured using standardized outcomes including overall healing rate, presence of anal pain, recurrence and need for repeat botulinum injection. Binary outcomes were assessed using logistic regression model. The analysis was performed using Stata version 13 (StataCorp, College Station, TX, USA). RESULTS: One hundred and one patients underwent 126 Botox injections within the study period. The mean first post-operative visit was at 1 month. The overall recurrence rate was 32%. The majority of patients were given 33 U. No statistically significant relationship between dose and recurrence was identified. The presence of pain at the first post-operative visit was a predictor of future recurrence (odds ratio 3.92, confidence interval 1.58-9.74, P = 0.003). CONCLUSION: Botox is an effective strategy for CAF. Low doses can be given with good efficacy as highlighted by our audit and has the potential for great cost saving. The best predictor of recurrence is the presence of pain at the first post-procedure visit.

Two common dentoalveolar defects are managed by a novel treatment approach. This article explains how the underlying mechanism that regulates bone physiology can be recruited to improve the response to surgical healing and presents the theoretical basis of this treatment method. Modern investigators have revealed the likely anatomic pathways through which this system operates. A specific set of rules can be defined to guide surgeons to design procedures that have the optimum potential for a successful outcome. These cases demonstrate that if this treatment method is followed, successful healing can be achieved.

BACKGROUND: This paper aimed to describe the training available and the process taken to establish a robotic colorectal surgery programme in a large Australian academic private hospital. Through this we hope to guide other surgeons and hospitals planning to introduce this technology in circumstances where such guidelines do not exist. METHODS: The available training and credentialing pathways are described, including the da Vinci Surgery Training Pathway provided by Intuitive Surgical and hospital-based supports. A proposed 9-point training and credentialing pathway is presented, along with the activities undertaken by each surgeon. RESULTS: From December 2011 to December 2013, 48 robotic colorectal procedures were performed at the Cabrini Hospital. Operations performed were as follows: 23 anterior resections, seven abdominoperineal resections, 11 rectopexies, three proctectomies and ileal pouch-anal anastomosis and four right hemicolectomies. There have been no conversions, and no major complications. There were no robot-specific complications. CONCLUSION: We believe that this thorough and methodical approach to introducing robotics to colorectal surgery has been safe and effective, and should be applicable to other surgeons and hospitals wishing to introduce robotic technology to colorectal surgery.
