RESUMO
BACKGROUND: The umbilical stoma (umbistoma) has been proposed as a viable alternative site for a temporary defunctioning stoma. Suggested advantages of the umbistoma include decreased number of surgical incisions required, improved cosmesis and ease of reversal surgery. This study aimed to assess the patient experience of umbilical loop ileostomies in rectal surgery, with the primary outcome being patient reported quality of life (QoL). METHODS: A total of 20 patients undergoing laparoscopic rectal cancer surgery were randomly allocated to have a defunctioning ileostomy at a conventional site (right iliac fossa) or at the umbilicus. Patient-reported QoL was assessed at 6 weeks using the Stoma-QoL questionnaire. Secondary outcomes were number of stomas reversed, length of time awaiting stoma reversal surgery, duration of operative time for stoma reversal, length of hospital stay following stoma reversal and rate of parastomal or post reversal incisional hernias. RESULTS: Patients who had an umbilical stoma scored significantly lower on the Stoma-QoL questionnaire compared to the conventional group, particularly on questions regarding feelings of tiredness, body insecurity and anxiety. No significant differences were observed between the two groups in relation to secondary outcomes. CONCLUSION: There may be potential disadvantages to the umbilical stoma with negative impacts on body image and subsequent increased social anxiety. Patient selection and adequate counselling will be important when considering an umbilical stoma. Further larger scale prospective studies are required to further validate the feasibility and longer-term safety of umbilical stomas in both clinical outcomes as well as patient QoL.

BACKGROUND: Acute surgical units (ASU) are increasingly being adopted and in our system are staffed by colorectal and non-colorectal general surgeons. This study aims to evaluate whether surgeon specialization was associated with improved outcomes in perianal abscess. METHODS: Patients with perianal abscess admitted to the ASU between 2016 and 2020 were identified from a prospective database and their medical records reviewed. Patients with IBD, treatment for fistula-in-ano within the preceding year, or perianal sepsis of non-cryptoglandular origin were excluded. Patients admitted under an ASU colorectal (CR) consultant were compared with those under a non-CR general surgeon in a retrospective cohort study. Primary outcome was perianal abscess recurrence. For those without initial fistula, hazard of recurrent abscess or fistula was analysed. Multivariable Cox PH regression analysis was performed. RESULTS: Four-hundred and eight patients were included (150 CR, 258 non-CR). The CR group more frequently had a fistula identified at index operation (34.0% versus 10.9%, P < 0.0001). However, Cox multivariable analysis found no difference in hazard of recurrent abscess between groups (HR 1.12, 95% CI 0.65-1.95, P = 0.681)). Abscess recurred in 18.7% CR and 15.5% non-CR. Subsequent fistula developed in 14.7% in both groups. For patients without initial fistula, there was no difference between groups in hazard of recurrent abscess or fistula (HR 1.18, 95% CI 0.69-2.01, P = 0.539). CONCLUSION: Surgeon specialization was not associated with improved outcomes for ASU patients with perianal abscess, albeit with potential selection bias. CR surgeons were more proactive identifying fistulas; this raises the possibility that drainage alone may be adequate treatment.

Background: Colorectal surgery in octogenarians is increasing in prevalence and good surgical outcomes have been demonstrated. However, functional status and independence remain the main patient consideration with limited data on the long-term functional outcomes. Methods: A retrospective analysis was conducted for all patients aged above 80 undergoing surgery for colorectal cancer (CRC) from January 2018 to December 2019. Functional status assessment was made as part of pre- and post-operative allied health clinic appointments. Eastern Cooperative Oncology Group (ECOG) performance scores were recorded. Loss of independence (LOI) was defined as the reduced capacity to perform pre-morbid activities of daily living (ADL) and requiring increased supports. Results: Forty-one patients aged 80 years or older had elective CRC resections with a median follow-up of 15 months [interquartile range (IQR): 8-20]. The median American Society of Anesthesiology (ASA) score was 3 and 90.2% (37/41) of patients had an ECOG score of 0 or 1. There was no 30-day mortality and 2 (4.9%) deaths occurred within 1 year. The median Clavien-Dindo score was 1, and 2 patients (4.9%) required unplanned intensive care unit (ICU) admissions. Twelve re-hospitalizations occurred with falls being the most common reason. LOI occurred in only 2 patients (4.9%) and on multivariate regression analysis, age and pre-morbid requirement of gait aids were predictive of LOI (P=0.042 and P=0.003, respectively). Gait aids were also associated with higher Clavien-Dindo scores (P=0.057) and increased length of stay (LOS) (P=0.009). Conclusions: Patients with advanced age undergoing surgery for CRC surgery can still have good post-operative outcomes and adequate functional recovery with pre-operative optimization and appropriate post-operative supports.
RESUMO
BACKGROUND: Left-handers make up 10%-12% of all surgeons. Surgical education and practice by nature has significant technical demands but there is a paucity of data on left-handers and training in surgery. The surgical curriculum has no specific salutation or recognition of left-handers and the contributions and challenges they represent. METHODS: The purpose of the study was to explore, describe and understand the lived experience of left-handed surgeons in relation to surgical education and training in Australia. Semi-structured interviews were used to gather in-depth information relating to the participants' experiences, viewpoints, beliefs and motivations. RESULTS: The responses of the participants involved were categorized using the data analysis method described by Colaizzi. Seven themes were identified: left-handed surgeons are universal adapters; left-handed instruments are not necessary for left-handed trainees; most left-handed trainees have experienced discrimination or negativity due to their laterality; ambidexterity is considered an advantage; communicating one's laterality is important; a formal mentoring program is not necessary; and simulation can be a complementary tool for left- handed trainees. Being a left-handed surgical trainee need not be a negative experience. CONCLUSION: With appropriate support and teaching, left-handed trainees can develop into excellent surgeons. The themes from this study can be used by trainees, trainers and Colleges of surgical training to build awareness and optimize the training of future left-handed surgeons.

BACKGROUND: As coronavirus (COVID-19) cases continue to rise, healthcare workers have been working overtime to ensure that all patients receive care in a timely manner. Our study aims to identify the impact and outcomes of COVID-19 on colorectal cancers presentations across the five major colorectal units in Melbourne, Australia. METHODS: This is a retrospective study from a prospectively collected database from the binational colorectal cancer audit (BCCA) registry, as well as inpatient records. All patients with colorectal cancer between Pre-COVID-19 period (1 July 2018-2030 June 2019) and COVID-19 period (1 July 2020-2030 June 2021) were compared. Benign pathology and other cancer types were excluded. RESULTS: A total of 1609 patients were included in the study (700 Pre-COVID-19 period, 906 COVID-19 period). During COVID-19 period, there was a higher proportion of emergency surgery (28.1% vs. 19.8%; P < 0.001), a higher nodal (P = 0.024) and metastatic stage (P = 0.018) at presentation, but no increase in the rate of return to operating theatres (P = 0.240), inpatient death (P = 0.019) or 30-day readmission (P = 0.000). There was also no difference in the post-operative surgical complications (P = 0.118). Utility of neoadjuvant therapy did not increase during the pandemic (P = 0.613). CONCLUSION: The heightened measures in the healthcare system ensured CRC patients still received their surgery in a timely fashion. With the current rise in the new strain of COVID-19 (Omicron), we have to continue to come up with new strategies to provide timely access to CRC care.

BACKGROUND: Postoperative pain is common in hemorrhoidectomy patients. Local anesthetic given either as an intraoperative pudendal nerve block or as a local wound infiltration may help alleviate postoperative pain. OBJECTIVES: This study sought to determine whether the addition of an intraoperative pudendal nerve block to a perianal local wound infiltration and standardized analgesia regimen was superior to a perianal local wound infiltration and standardized analgesia regimen alone in reducing early postoperative pain following hemorrhoidectomy. The secondary objective was to measure differences between treatment groups in perceived perianal numbness, oral opioid requirements, and adverse events. DESIGN: This study was a prospective, single-blinded randomized controlled trial approved by the Eastern Health Human Research and Ethics Committee in Melbourne, Australia (registration number: E09/2014). SETTINGS: Patients were recruited across 3 Australian hospitals. PATIENTS: Eighty patients with symptomatic hemorrhoids requiring hemorrhoidectomy in colorectal surgical outpatient clinics were successfully recruited and enrolled in the study, with 1 patient later dropping out. INTERVENTION: Patients were randomly assigned to either the pudendal nerve block group or a control group. The pudendal nerve block group received 5 mL bupivacaine 0.5% with adrenaline 1:200,000 to both pudendal nerve trunks bilaterally. Both groups received 10 mL of the same local anesthetic injected into the post-hemorrhoidectomy wound bed. MAIN OUTCOME MEASURES: Visual analogue scales were used to record patient pain scores. Dichotomous (yes/no) answers were recorded for secondary objectives. RESULTS: There were no significant differences in postoperative pain between groups at 4 hours, 8 hours, 12 hours, or 24 hours. Additionally, there were no significant differences between groups with respect to perceived perianal numbness, oral opioid usage or adverse events. LIMITATIONS: The authors recognize that without a nerve stimulator, an argument can be made that the pudendal nerve block was not actually achieved. CONCLUSION: Pudendal nerve block does not appear to demonstrate additional benefit in post-hemorrhoidectomy pain reduction beyond local anesthetic to the wound.

BLOQUEO DEL NERVIO PUDENDO PARA EL DOLOR POSHEMORROIDECTOMA ESTUDIO PROSPECTIVO, ALEATORIO, CONTROLADO, CIEGO: ANTECEDENTES:El dolor posoperatorio es común en pacientes luego de una hemorroidectomía. La administración de anestésico local como bloqueo del nervio pudendo intraoperatorio o infiltración local de la herida puede ayudar a aliviar el dolor posoperatorio.OBJETIVOS:Determinar si agregar un bloqueo intraoperatorio del nervio pudendo a una infiltración local perianal de la herida y un régimen de analgesia estandarizado fue superior a una infiltración local perianal de la herida más un régimen de analgesia estandarizado para reducir el dolor posoperatorio precoz después de una hemorroidectomía. Los objetivos secundarios incluyeron sensación de adormecimiento perianal, requerimientos de opioides orales y eventos adversos informados.DISEÑO:Este estudio fue un ensayo controlado aleatorio, prospectivo, ciego, aprobado por el Comité de Ética e Investigación en Humanos de Eastern Health en Melbourne, Australia (número de registro: E09 / 2014).ESCENARIO:Los pacientes fueron reclutados en tres hospitales australianos.PACIENTES:Ochenta pacientes se inscribieron con éxito en el estudio, y más tarde un paciente abandonó.INTERVENCIÓN:Los pacientes fueron asignados al azar al grupo de bloqueo del nervio pudendo o al grupo control. El grupo de bloqueo del nervio pudendo recibió 5 ml de bupivacaína al 0,5% con adrenalina 1: 200.000 en ambos troncos del nervio pudendo bilateralmente. Ambos grupos recibieron 10 ml del mismo anestésico local inyectado en el lecho de la herida posterior a la hemorroidectomía.PRINCIPALES VARIABLES ANALIZADAS:Se utilizaron escalas analógicas visuales para registrar las puntuaciones de dolor del paciente. Se registraron respuestas dicotómicas (sí / no) para los objetivos secundarios.RESULTADOS:No hubo diferencias significativas en el dolor posoperatorio entre los grupos a las 4, 8, 12 o 24 horas. Además, no hubo diferencias significativas entre los grupos con respecto al adromecimiento perianal percibido, el uso de opioides orales o los eventos adversos.LIMITACIONES:Sin el uso de un estimulador nervioso, se puede argumentar que el bloqueo del nervio pudendo no se logró realmente.CONCLUSIÓNES:El bloqueo del nervio pudendo no parece demostrar un beneficio adicional en la reducción del dolor posterior a la hemorroidectomía más allá del anestésico local en la herida.

AIM: A diverting ileostomy is typically performed to divert intestinal contents in high-risk colorectal anastomoses. Ileostomy closure is associated with high rates of postoperative Clostridium difficile infection (CDI). Risk factors for the development of CDI are unclear; however, a correlation has been observed with delayed closure. This study aimed to assess the odds of developing CDI in patients who had a delay to reversal of ileostomy, compared to those who had no delay. METHODS: A retrospective cohort study was conducted of patients undergoing reversal of ileostomy between 2010 and 2019 at a single tertiary centre. A delay to reversal of ileostomy was defined if the procedure was performed at >365 days following the index procedure. CDI was defined as the presence of Clostridium difficile toxin associated with diarrhoea. Univariable logistic regression analysis was performed to estimate odds of CDI for each covariable, comparing patients who had a delay to reversal of ileostomy with those who did not. Multivariable logistic regression analysis was used to adjust for the potential confounding effects of covariables. RESULTS: Of 195 patients, 11 (5.6%), developed postoperative CDI. Multivariable analysis showed that delay to reversal of ileostomy was associated with a nearly 7-fold increase in odds of CDI (OR = 6.95, CI: 1.06-81.6; p-value = 0.03). CONCLUSION: A delay to reversal of ileostomy of >365 days was associated with a higher incidence of CDI postoperatively. Careful consideration should be given to the timing of reversal and appropriate preoperative counselling of patients.

AIM: To compare the adenoma detection rate (ADR) between gastroenterologists and colorectal surgeons at Box Hill Hospital, Melbourne, Australia. METHODS: A total of 300 colonoscopies performed by gastroenterologists and colorectal surgeons at Box Hill Hospital were retrospectively reviewed from May 2016 to June 2017. Exclusion criteria were: Patients ≤ 50 years old, colonoscopies with failure of caecal intubation, patients who previously had colon cancer and/or a colonic resection, history of polyposis syndromes or inflammatory bowel disease, or a colonoscopy within the last 10 years. Patient demographics, indications, symptoms and procedural-related outcomes were measured. RESULTS: The ADR was not significantly different between gastroenterologists and colorectal surgeons (34% vs 34.67%; P = 0.90). The adjusted odds ratio correcting for gender, age, 1st degree relative with colorectal cancer, previous colonoscopy, trainee involvement and caecal or terminal ileum intubation rate was 1.19 (0.69-2.05). CONCLUSION: Both specialties at our institution exceed benchmark standards suggested by published Australian and American guidelines. An association between endoscopist specialty and ADR was not observed.
RESUMO
Anastomotic leak (AL) can be a devastating complication in colorectal surgery. While it is less frequent in the modern era, it still results in significant morbidity and mortality, prolonged hospital stays and increases the costs and demands on health services. There is inevitable interplay between patient physiology and technical factors that predispose a patient to AL. Obesity, preoperative total proteins, male gender, ongoing anticoagulant treatment, intraoperative complication and number of hospital beds have been identified as independent risk factors. This has led to an online risk calculator for AL. Non-steroidal anti-inflammatory drugs and neoadjuvant chemoradiotherapy have also been implicated, but no significant evidence has yet been found to support causation. In addition, technical factors such as type of anastomosis, mechanical bowel preparation, drains, omentoplasty and faecal diversion have failed to show significant differences in AL rates. Early diagnosis and intervention in AL is essential in reducing the rates of morbidity and mortality. Clinical assessment has high sensitivity but low specificity and should be used in combination with imaging techniques to get a diagnosis. C-reactive protein is also a useful marker. The management will depend on the grade of AL and the clinical state of the patient. Management options include conservative measures such as antibiotics and/or percutaneous drainage to more invasion procedures such as open drainage and/or Hartmann's procedure. In conclusion, ALs will forever pose challenges to the surgeon in diagnosis and management. It is often the yardstick by which each surgeon is measured and is the source of significant morbidity to patients and health care services worldwide. As a result, a low threshold for investigation and intervention is mandatory to ensure better outcomes and lower overall mortality and morbidity.
RESUMO
Tension pneumoperitoneum is commonly caused by gastrointestinal perforation and pulmonary causes are extremely rare. We present a case of a 47-year-old male post motor vehicle accident with a suspected left-sided haemopneumothorax on initial chest x-ray. CT of the chest post chest tube insertion showed a left-sided diaphragmatic rupture and an extensive diaphragmatic hernia. While en-route to the operating theatre, the intubated patient developed tension pneumoperitoneum with positive pressure ventilation and required immediate surgical intervention and repair. A review of the literature around tension pneumoperitoneum and diaphragmatic hernia in trauma is discussed.
RESUMO
Right iliac fossa pain is a common acute general surgery presentation, and computer tomography (CT) is often used as an aid in determining the diagnosis. CT can play an important role in differentiating malignant and inflammatory causes of caecal wall thickening if certain key features are identified. Two patients with similar presentations of right iliac fossa pain had pre-operative CT, which showed inflammation and caecal thickening, the first was focal with homogenous enhancement, and the second eccentric with stratification. At operation, these were proven to be malignant and inflammatory caecal thickening. Although the clinical presentation of appendicitis and caecal carcinoma may be similar, and the correct recognition and interpretation of differentiating CT characteristics enables the patient for an appropriately tailored operation.

PURPOSE: Resource limitations are a concern in most modern public hospital systems. The aim of this study is to prospectively quantify the total caseload of a tertiary colorectal surgery unit to identify areas of redundancy. METHODS: Data was collected prospectively at all points of clinical care (outpatient clinic, inpatient referrals, operating theatre and endoscopy) between March 2014 and March 2015 using specifically designed templates. The final data was analysed using descriptive statistics. RESULTS: During the study period, 4012 patient episodes were recorded: 2871 in outpatient clinic, 186 as emergency patient referrals, 541 at colonoscopy and 414 at surgery. The largest component of the caseload was made up primarily of colonoscopy results follow-up, protocol review for previous cancer or polyps and post-operative review. Sixty-eight percent of these episodes did not result in any active intervention such as further tests or surgery. Most new outpatient referrals were undifferentiated, with the most common indications being minor rectal bleeding, non-specific gastrointestinal symptoms, and minor non-bleeding anorectal problems. Of the new referrals, 56 % were booked for a colonoscopy, and only 13.3 % were booked directly for elective surgery. CONCLUSION: A large component of the caseload of a tertiary colorectal surgery unit is made up of post-colonoscopy, post-operative, and surveillance protocol follow-up, with a significant proportion of patients not requiring any active intervention. The majority of new referrals are undifferentiated and result in a low rate of direct booking for operative intervention. Rationalisation of this resource using evidence-based methods could reduce redundancy, workload, and cost.

There is level one evidence to support combined mechanical and chemical thromboprophylaxis for 7-10 days after colorectal cancer surgery, but there remains a paucity of data to support extended prophylaxis after discharge. The aim of this clinical review is to summarise the currently available evidence for extended venous thromboprophylaxis after elective colorectal cancer surgery. Clinical review of the major clinical guidelines and published clinical data evaluating extended venous thromboprophylaxis after elective colorectal cancer surgery. Five major guideline recommendations are outlined, and the results of the five published randomised controlled trials are summarised and reviewed with a specific focus on the efficacy and cost-effectiveness of extended heparin prophylaxis to prevent clinically relevant post-operative venous thromboembolism (VTE) after colorectal cancer surgery. Extended VTE prophylaxis after colorectal cancer surgery reduces the incidence of asymptomatic screen detected deep venous thrombosis (DVT) only, with no demonstrable reduction in symptomatic DVT, symptomatic PE, or VTE related death. Evidence for cost-effectiveness is limited. As the incidence of clinical VTE is very low in this patient subgroup overall, future research should be focused on higher risk patient subgroups in whom a reduction in VTE may be both more demonstrable and clinically relevant.

AIM: To determine the frequency of identification of the triradiate fold during colonoscopy and evaluate its reliability as a marker of caecal intubation. METHODS: One hundred consecutive patients undergoing colonoscopy in a tertiary hospital colorectal unit from May to September 2013 were studied. Video documentation of the caecum was recorded and shown to consultant colorectal surgeons on the unit. Each reviewer was asked through a series of questions to independently identify the triradiate fold. The main outcome was the frequency of visualisation of the triradiate fold in the caecum. RESULTS: The triradiate fold was seen on average in 18% of cases, but inter-observer agreement was poor. There were only four patients (4%) in which all reviewers agreed on the presence of a triradiate fold. In patients who had undergone previous appendicectomy, the appendiceal orifice was less frequently seen compared with patients who had not undergone appendicectomy. CONCLUSION: The triradiate fold is infrequently seen during colonoscopy and is therefore an unreliable landmark of caecal intubation.
