RESUMO
AIM: Attention is increasingly being turned to functional outcomes as being central to colorectal cancer (CRC) survivorship. The current literature may underestimate the impact of evacuatory dysfunction on patient satisfaction with bowel function after anterior resection (AR) for CRC. The aim of this study was to investigate the impact of post-AR symptoms of storage and evacuatory dysfunction on patient satisfaction and health-related quality of life (HRQoL). METHOD: A cross-sectional study was performed at an Australian hospital of patients post-AR for CRC (2012-2021). The postoperative bowel function scores used were: low anterior resection syndrome (LARS), St Mark's incontinence, Cleveland Clinic constipation and Altomare obstructive defaecation syndrome scores. Eight 'storage' and 'evacuatory' dysfunction symptoms were derived. A seven-point Likert scale measured patient satisfaction. The SF36v2® measured HRQoL. Linear regression assessed the association between symptoms, patient satisfaction and HRQoL. RESULTS: Overall, 248 patients participated (mean age 70.8 years, 57.3% male), comprising 103 with rectal cancer and 145 with sigmoid cancer. Of the symptoms that had a negative impact on patient satisfaction, six reflected evacuatory dysfunction, namely excessive straining (p < 0.001), one or more unsuccessful bowel movement attempt(s)/24 h (p < 0.001), anal/vaginal digitation (p = 0.005), regular enema use (p = 0.004), toilet revisiting (p = 0.004) and >10 min toileting (p = 0.004), and four reflected storage dysfunction, namely leaking flatus (p = 0.002), faecal urgency (p = 0.005), use of antidiarrhoeal medication (p = 0.001) and incontinence-related lifestyle alterations (p < 0.001). A total of 130 patients (53.5%) had 'no LARS', 56 (23.1%) had 'minor LARS' and 57 (23.4%) had 'major LARS'. Fifty-seven (44.5%) patients classified as having 'no LARS' had evacuatory dysfunction. CONCLUSION: Postoperative storage and evacuatory dysfunction symptoms have an adverse impact on patient satisfaction and HRQoL post-AR. The importance of comprehensively documenting symptoms of evacuatory dysfunction is highlighted. Further research is required to develop a patient satisfaction-weighted LARS-specific HRQoL instrument.

BACKGROUND: The role of adjuvant chemotherapy (AC) in stage III rectal cancer (RC) has been argued based on evidence from its use in colon cancer. Previous trials have analysed disease-free and overall survivals as endpoints, rather than disease recurrence. This study compares the competing risks incidences of recurrence and cancer-specific death between patients who did and did not receive AC for stage III RC. METHODS: Consecutive patients who underwent a potentially curative resection for stage III RC (1995-2019) at Concord Hospital, Sydney, Australia, were studied. AC was considered following multidisciplinary discussion. Primary outcome measures were the competing risks incidences of disease recurrence and cancer-specific death. Associations between these outcomes and use of AC (and other variables) were tested by regression modelling. RESULTS: Some 338 patients (213 male, mean age 64.4 years [SD12.7]) were included. Of these, 208 received AC. The use of AC was associated with resection year (adjusted OR [aOR] 1.74, 95%CI 1.27-2.38); age ≥75 years (aOR0.04, 95%CI 0.02-0.12); peripheral vascular disease (aOR0.08, 95%CI 0.01-0.74); and postoperative abdomino-pelvic abscess (aOR0.23, 95%CI 0.07-0.81). One hundred fifty-seven patients (46.5%) were diagnosed with recurrence; death due to RC occurred in 119 (35.2%). After adjustment for the competing risk of non-cancer death, neither recurrence nor RC-specific death was associated with AC (HR0.97, 95%CI 0.70-1.33 and HR0.72, 95%CI 0.50-1.03, respectively). CONCLUSION: This study found no significant difference in either recurrence or cancer-specific death between patients who did and did not receive AC following curative resection for stage III RC.

OBJECTIVE: To examine the independent prognostic value of ALN status in patients with stage III CRC. SUMMARY OF BACKGROUND DATA: Early CRC staging classified nodal involvement by level of involved nodes in the operative specimen, including both locoregional and apical node status, in contrast to the American Joint Committee on Cancer/tumor nodes metastasis (TNM) system where tumors are classified by the number of nodes involved. Whether ALN status has independent prognostic value remains controversial. METHODS: Consecutive patients who underwent curative resection for Stage III CRC from 1995 to 2012 at Concord Hospital, Sydney, Australia were studied. ALN status was classified as: (i) ALN absent, (ii) ALN present but not histologically involved, (iii) ALN present and involved. Outcomes were the competing risks incidence of CRC recurrence and CRC-specific death. Associations between these outcomes and ALN status were compared with TNM N status results. RESULTS: In 706 patients, 69 (9.8%) had an involved ALN, 398 (56.4%) had an uninvolved ALN and 239 (33.9%) had no ALN identified. ALN status was not associated with tumor recurrence [adjusted hazard ratio (HR) 1.02, 95% confidence interval (CI) 0.84-1.26] or CRC-specific death (HR 1.14, CI 0.91-1.43). However, associations persisted between TNM N-status and both recurrence (HR 1.58, CI 1.21-2.06) and CRC-specific death (HR 1.59, CI 1.19-2.12). CONCLUSIONS: No further prognostic information was conferred by ALN status in patients with stage III CRC beyond that provided by TNM N status. ALN status is not considered to be a useful additional component in routine TNM staging of CRC.

AIM: Clinical presentation with large bowel obstruction has been proposed as a predictor of poor long-term oncological outcomes after resection for colorectal cancer. This study examines the association between obstruction and recurrence and cancer-specific death after resection for colon cancer. METHOD: Consecutive patients who underwent resection for colon cancer between 1995 and 2014 were drawn from a prospectively recorded hospital database with all surviving patients followed for at least 5 years. The outcomes of tumour recurrence and colon cancer-specific death were assessed by competing risks multivariable techniques with adjustment for potential clinical and pathological confounding variables. RESULTS: Recurrence occurred in 271 of 1485 patients who had a potentially curative resection. In bivariate analysis, obstruction was significantly associated with recurrence [hazard ratio (HR) 2.23, CI 1.52-3.26, p < 0.001] but this association became nonsignificant after adjustment for confounders (HR 1.53, CI 0.95-2.46, p = 0.080). Colon cancer-specific death occurred in 238 of 295 patients who had a noncurative resection. Obstruction was not significantly associated with cancer-specific death (HR 1.02, CI 0.72-1.45, p = 0.903). In patients who had a noncurative resection, the competing risks incidence of colon cancer-specific death was not significantly greater in obstructed than in unobstructed patients (HR 1.02, CI 0.72-1.45, p = 0.903). CONCLUSION: Whilst the immediate clinical challenge of an individual patient presenting with large bowel obstruction must be addressed by the surgeon, the patient's long-term oncological outcomes are unrelated to obstruction per se.

Background: There has been much debate as to the importance of mechanical bowel preparation (MBP) and oral antibiotic agents (OAB) prior to elective colorectal surgery over the past two decades. There is no consensus between international guidelines. Methods: The Australia and New Zealand Mechanical Bowel Preparation and Oral Antibiotics (ANZ-MBP-OAB) questionnaire was distributed to colorectal surgeons after institutional board approval assessing specialist attitudes toward 18 enhanced recovery after surgery (ERAS) interventions. Data were analyzed using a rating scale and graded response model in item response theory (IRT) on Stata MP, version 15 (StataCorp LP, College Station, TX). Specialist attitudes toward the effectiveness of MBP and OAB strategies in providing better short-term outcomes was ranked alongside other ERAS interventions. This was followed by specific questions examining current practice, perspectives, and trends. Results: Ninety-five of 300 (31.7%) colorectal surgeons in Australia and New Zealand participated in the survey. Statistical modeling was achieved in 13 ERAS interventions. Compared with other ERAS interventions, the use of MBP with OAB and MBP alone ranked nine of 13 and 10 of 13, respectively, in order of effectiveness in providing better short-term outcomes after colorectal surgery. Oral antibiotic agents alone was not considered effective. Mechanical bowel preparation with OAB was considered to be the best strategy in both colon (37%) and rectal surgery (48%) but current practice varied substantially from perspective. Mechanical bowel preparation alone was strongly favored in rectal surgery (81%) with only 14% using MBP with OAB. In colon surgery, only 10% used MBP with OAB, with MBP alone (45%) and no preparation (45%) being equally the most commonly used strategies. Conclusions: Among Australian and New Zealand colorectal surgeons, MBP with OAB was considered the best bowel preparation strategy. However, despite an awareness of its benefits, MBP with OAB has yet to be widely adopted into clinical practice or guidelines in Australia and New Zealand.

OBJECTIVES: To determine the age-standardised prevalence of inflammatory bowel disease (IBD) in a metropolitan area of Sydney, with a focus on its prevalence among older people. DESIGN, SETTING: Population-based epidemiological study of people with IBD in the City of Canada Bay, a local government area in the inner west of Sydney, during 1 March 2016 - 10 November 2016. PARTICIPANTS: Patients diagnosed with confirmed IBD according to the Copenhagen or revised Porto criteria. MAIN OUTCOME MEASURES: Crude prevalence of IBD, including Crohn disease and ulcerative colitis; age-standardised prevalence of IBD, based on the World Health Organization standard population; prevalence rates among people aged 65 years or more. RESULTS: The median age of 364 people with IBD was 47 years (IQR, 34-62 years); 185 were women (50.8%). The crude IBD prevalence rate was 414 cases (95% CI, 371-456 cases) per 100 000 population; the age-standardised rate was 348 cases (95% CI, 312-385 cases) per 100 000 population. The age-standardised rate for Crohn disease was 166 cases (95% CI, 141-192 cases) per 100 000 population; for ulcerative colitis, 148 cases (95% CI, 124-171 cases) per 100 000 population. The IBD prevalence rate in people aged 65 years or more was 612 cases (95% CI, 564-660 cases) per 100 000, and for those aged 85 years or more, 891 cases (95% CI, 833-949 cases) per 100 000; for people under 65, the rate was 380 cases (95% CI, 342-418 cases) per 100 000. CONCLUSIONS: We found that the prevalence of confirmed IBD in a metropolitan sample was highest among older people. Challenges for managing older patients with IBD include higher rates of comorbid conditions, polypharmacy, and cognitive decline, and the immunosuppressive nature of standard therapies for IBD.

BACKGROUND: Haemorrhoidectomy is associated with significant post-operative pain which is primarily managed pharmacologically. Whether a non-pharmacological adjunct such as a checklist can improve pain outcomes after an open haemorrhoidectomy has yet to be studied. The purpose of this study was to determine if a patient-completed checklist of prescribed post-haemorrhoidectomy pain medications would improve pain management after surgery. METHODS: We conducted a dual-centre randomized controlled trial of patients undergoing a Milligan-Morgan haemorrhoidectomy for symptomatic third or fourth degree haemorrhoids. Thirty-five patients were randomized into either a control group which received post-operative pain medication plus a visual analogue scale (VAS) form, or an intervention group which received a post-operative medication checklist in addition to the items the control group received. Both groups recorded their pain levels on the VAS forms at 10.00, 14.00 and 20.00 hours each day for 14 days post-operatively. RESULTS: Patients in the checklist group reported a significantly greater reduction in mean VAS pain score of 2.51 (95% confidence interval (CI) 1.34-3.68; P < 0.001) between day 1 post-op and day 14 post-op compared to 1.86 (95% CI 0.77-2.95; P = 0.001) for the control group. There was no significant difference between mean pain experienced by patients in either group over each of the 14 days individually or overall (P = 0.07). CONCLUSION: The pain medication checklist lead to a greater reduction in pain between day 1 and 14 after an open haemorrhoidectomy compared to standard care but did not significantly reduce mean pain across any individual days or overall.

PURPOSE: Internal hernia (IH) after laparoscopic left-sided colorectal resection (small bowel herniating underneath the neo-descending colon) can be a potentially devastating complication, resulting in acute small bowel obstruction or ischemia. IH has been described as a rare occurrence in a few retrospective case series; however, patients undergoing laparoscopic resection seem to be more prone to this complication. We assessed the prevalence of IH in a large cohort of patients who had undergone laparoscopic left-sided colorectal resection for colon or rectal cancer (CRC). METHODS: A database of consecutive patients at a single institution from 2012 to 2017 was reviewed. Postoperative abdominal computed tomography (CT) scans performed for routine cancer follow-up between 3 and 36 months after surgery were assessed retrospectively. RESULTS: During the study period, 276 patients had undergone anterior resection for CRC, with 206 (75%) having been performed laparoscopically. A total of 198 eligible patients were identified, and a follow-up CT scan was available in 105 (53%) of these patients (median time to CT 10 months, range 3-34). Only one of the 198 (0.5%) patients presented with an acute small bowel obstruction secondary to an IH during follow-up. However, the prevalence of asymptomatic IH was noted to be much higher in the postoperative CT scans occurring in 22 of 105 (21%) patients. CONCLUSION: Asymptomatic IH after laparoscopic left-sided colorectal resection is common. Given the potential risk of acute small bowel obstruction and ischemia, routine closure of the mesenteric defect should be considered.

Recurrent neo-left colonic volvulus is a rare complication following anterior resection. The conventional approach to treating recurrent volvulus is a large bowel resection with anastomosis or colostomy formation after successful endoscopic decompression. However, in elderly and comorbid patients, this can result in significant morbidity or mortality. Laparoscopic colopexy is a less invasive alternative that has not been previously reported for the treatment of neo-left colonic volvulus. We describe a case of an 86-year-old male who presented with recurrent neo-left colonic volvulus 10 years post-laparoscopic anterior resection for cancer. A laparoscopic colopexy was performed to resolve the volvulus and prevent future recurrence. Interrupted prolene sutures were used to fix the neo-left colon to the posterior stomach and the left lateral abdominal wall. The patient had an uncomplicated postoperative recovery and was discharged 6 days after surgery. He was well at 6 months follow-up.
RESUMO
This article describes the development of a structured MRI reporting template and diagrammatic worksheet for perianal sepsis through collaboration between radiologists and colorectal surgeons at our institution, and the rationale behind each component of the worksheet. Benefits of this reporting worksheet include optimizing communication of key imaging findings that have a real impact on patient management, less time spent on reporting the study, and easier comparison between studies. We illustrate the utility of the report template with case studies. We summarize the current surgical approaches to perianal sepsis to help radiologists focus on reporting the findings relevant to surgical planning.

BACKGROUND: While most colorectal cancer (CRC) recurrences reportedly occur within 3 years following curative treatment, many studies are limited by short-term follow-up. This study examines the time to recurrence of CRC in a large Australian cohort with a long follow-up period and assesses whether time to recurrence has changed over time. METHODS: A comprehensive prospective database of patients undergoing resection for CRC is maintained at Concord Hospital, Sydney. Demographic and time to recurrence data were extracted for patients who developed a recurrence following potentially curative resection for colon cancer from 1995 to 2010 and rectal cancer from 1971 to 2010. Non-deceased patients had a minimum of 5 years follow-up. RESULTS: Between 1995 and 2010, 2575 patients with CRC underwent surgery. After exclusions, 386 had recurrence following potentially curative resection, ranging from 1 to 172.5 months (median 20.3) after treatment. Within 1 year, 27.5% recurred, 57.5% by 2 years, 74.6% by 3 years, 85.5% by 4 years and 89.6% by 5 years. There was no difference in time to recurrence between colon and rectal cancers (P = 0.674). Among patients having a potentially curative resection for rectal cancer between 1971 and 2010, 386 recurred. There was no difference in time to recurrence by decade (P = 0.863). CONCLUSION: The majority of recurrences occurred within 3 years of curative treatment. Had surveillance been limited to 5 years, detection of more than 10% of recurrences would have been delayed. Time to recurrence for rectal cancer has not changed in over 40 years, despite treatment advances.

The pTNM staging system for colorectal cancer (CRC) is not entirely effective in discriminating between potentially curative and non-curative resections because it does not account for local residual tumour in patients with stages I, II or III. This study aimed to evaluate the prognostic importance of histologically verified tumour in any line of resection of the bowel resection specimen (TLR) in relation to pTNM stages and to demonstrate how TLR may be integrated into pTNM staging. Information on patients in the period 1995 to 2010 with complete follow-up to the end of 2015 was extracted from a prospective database of CRC resections. The outcome variables were the competing risks incidence of CRC recurrence and CRC-specific death. After exclusions, 2220 patients remained. In 1930 patients with pTNM stages I-III tumour, recurrence was markedly higher in those with TLR than in those without (HR 6.0, 95% CI 4.2-8.5, p < 0.001) and this persisted after adjustment for covariates associated with recurrence. CRC-specific death was markedly higher in the presence of TLR (HR 7.7, CI 5.3-11.2, p < 0.001), which persisted after adjustment for relevant covariates. These results justify removing patients with TLR from pTNM stages I to III and placing them in stage IV, thereby allowing the categorisation of all patients with any known residual tumour into three prognostically distinct groups. This study demonstrates how TLR may be integrated into pTNM staging, thus improving the definition of the three stages which are considered potentially curable (I, II and III).

BACKGROUND: Peristomal pyoderma gangrenosum (PPG) is an unusual but potentially devastating condition that is difficult to diagnose and manage. METHODS: This was a single centre, retrospective review of a prospectively collected database. Included were consecutive patients referred to a stoma therapy clinic at a single institution between 2005 and 2016. Main outcomes of interest were management strategies and outcome of patients with PPG including time to healing and recurrence. RESULTS: Of 1295 consecutive patients who underwent stoma formation, 12 patients with PPG were identified. The mean age at the time of diagnosis of PPG was 43.5 years (range 19-72 years). Five cases (41.7%) were associated with Crohn's disease and five cases (41.7%) with ulcerative colitis. The median duration of days between stoma formation and PPG diagnosis was 101.5 days (mean duration was 670 days (range 14-2641 days)). Nearly all patients (91.7%) were referred to a dermatologist. Majority (66.7%) were managed in an outpatient setting. For those requiring inpatient management, the mean length of stay was 13.5 days (range 3-31 days). Five patients had a biopsy and seven patients were diagnosed with PPG by dermatologist without biopsy. A range of oral and topical steroids, steroid injections, dressings, anti-inflammatories, antibiotics, tacrolimus and analgesia was used in the management of PPG. All patients achieved complete healing of PPG, with only one patient developing a recurrence of PPG. The mean duration of time to achieve complete healing of PPG was 282 days (range 28-1751 days). DISCUSSION: Medical management of PPG was effective with complete healing and low recurrence. The average duration to complete healing of PPG was approximately 9 months.

PURPOSE: During a laparotomy, the peritoneum is exposed to the cold, dry ambient air of the operating room (20°C, 0%-5% relative humidity). The aim of this review is to determine whether the use of humidified and/or warmed CO2 in the intraperitoneal environment during open or laparoscopic operations influences postoperative outcomes. METHODS: A review was performed in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The PubMed, OVID MEDLINE, Cochrane Central Register of Controlled Trials and Embase databases were searched for articles published between 1980 and 2016 (October). Comparative studies on humans or nonhuman animals that involved randomized controlled trials (RCTs) or prospective cohort studies were included. Both laparotomy and laparoscopic studies were included. The primary outcomes identified were peritoneal inflammation, core body temperature, and postoperative pain. RESULTS: The literature search identified 37 articles for analysis, including 30 RCTs, 7 prospective cohort studies, 23 human studies, and 14 animal studies. Four studies found that compared with warmed/humidified CO2, cold, dry CO2 resulted in significant peritoneal injury, with greater lymphocytic infiltration, higher proinflammatory cytokine levels and peritoneal adhesion formation. Seven of 15 human RCTs reported a significantly higher core body temperature in the warmed, humidified CO2 group than in the cold, dry CO2 group. Seven human RCTs found lower postoperative pain with the use of humidified, warmed CO2. CONCLUSION: While evidence supporting the benefits of using humidified and warmed CO2 can be found in the literature, a large human RCT is required to validate these findings.
