RESUMO
BACKGROUND: Patients with inflammatory bowel disease (IBD) who have had a total colectomy remain with their rectum in situ, and are therefore at risk of rectal carcinoma. It is not clear how high the incidence of rectal cancer is in this cohort. The primary objective of this meta-analysis was to estimate the incidence of rectal cancer in patients with ulcerative colitis or Crohn's disease who have undergone colectomy but have a residual rectum, and to identify the risk factors for its development. In doing so, we explore the current recommendations for screening processes for these patients. METHODS: A systematic review of the literature was performed. Five databases (Medline, Embase, Pubmed, Cochrane Library and Scopus) were searched from inception to 29 October 2021, to identify studies adhering to the population, intervention, control and outcomes (PICO) criteria. The included studies were critically appraised, and the relevant data was extracted. Cancer incidence was estimated from the reported information. Risk stratification was analysed using RevMan. A narrative approach was undertaken for the exploration of the existing screening guidelines. RESULTS: Data from 23 of the 24 identified studies was suitable for analysis. The pooled incidence of rectal carcinoma was calculated to be 1.3%. Subgroup analysis showed an incidence of 0.7% and 3.2% for patients with a de-functioned rectal stump and ileorectal anastomosis, respectively. Patients with a history of a colorectal carcinoma were more likely to have a subsequent diagnosis of rectal carcinoma (RR 7.2, 95% CI 2.4-21.1). Patients with previous colorectal dysplasia were also at higher risk (RR 5.1, 95% CI 3.1-8.2). No universal standardised guidance regarding screening for this cohort could be identified in the available literature. CONCLUSIONS: The overall risk of malignancy was estimated to be 1.3%, which is lower than previously reported. There is a need for clear and standardised screening guidance for this group of patients.

OBJECTIVES: Colorectal polyp cancers present clinicians with a treatment dilemma. Decisions regarding whether to offer segmental resection or endoscopic surveillance are often taken without reference to good quality evidence. The aim of this study was to develop a treatment algorithm for patients with screen-detected polyp cancers. DESIGN: This national cohort study included all patients with a polyp cancer identified through the Scottish Bowel Screening Programme between 2000 and 2012. Multivariate regression analysis was used to assess the impact of clinical, endoscopic and pathological variables on the rate of adverse events (residual tumour in patients undergoing segmental resection or cancer-related death or disease recurrence in any patient). These data were used to develop a clinically relevant treatment algorithm. RESULTS: 485 patients with polyp cancers were included. 186/485 (38%) underwent segmental resection and residual tumour was identified in 41/186 (22%). The only factor associated with an increased risk of residual tumour in the bowel wall was incomplete excision of the original polyp (OR 5.61, p=0.001), while only lymphovascular invasion was associated with an increased risk of lymph node metastases (OR 5.95, p=0.002). When patients undergoing segmental resection or endoscopic surveillance were considered together, the risk of adverse events was significantly higher in patients with incomplete excision (OR 10.23, p<0.001) or lymphovascular invasion (OR 2.65, p=0.023). CONCLUSION: A policy of surveillance is adequate for the majority of patients with screen-detected colorectal polyp cancers. Consideration of segmental resection should be reserved for those with incomplete excision or evidence of lymphovascular invasion.

BACKGROUND: Increasing lymph node ratio (LNR) (ratio of metastatic lymph nodes to the total number of harvested lymph nodes) and extramural vascular invasion (EMVI) have been proposed as adverse prognostic indicators in colorectal cancer, although their use remains variable and controversial. The aim of the present study was to assess the prognostic value of LNR and EMVI in predicting survival for patients undergoing curative colon cancer resection. METHODS: Between 2006 and 2012, 922 patients underwent curative colon cancer resection. Surgical technique and pathological assessment did not change during the study period. Clinical and pathological data were collected from a prospectively maintained database. The primary outcome measure was overall survival and disease-free survival. LNR was separated into five categories based on three previously calculated cutoff values: LNR 0 (no lymph nodes involved), LNR 1 (ratio 0.01<0.17), LNR 2 (ratio 0.18-0.41), LNR 3 (ratio 0.42-0.69), and LNR 4 (ratio >0.70). RESULTS: Nine hundred and twenty-two patients underwent colon cancer resection. The median follow-up for survivors was 52.8 months (IQR 34.6-77.6). The median total number of lymph nodes harvested was 16 (IQR13-22). On multivariate analysis, both pN and LNR were strongly associated with overall and disease-free survival. Using the Akaike information criterion (AIC), LNR had greater prognostic value compared with pN. For overall survival, compared with patients in LNR category 0, hazard ratios (95% CI) for those in categories 1, 2, 3 and 4 were 1.37 (1.03,1.82), 2.37 (1.70,3.30), 2.40 (1.57,3.65) and 5.51 (3.16,9.58), respectively. For disease-free survival, patients had hazard ratios (95% CI) of 1.78 (1.25,2.52), 3.79 (2.56,5.61), 2.60 (1.50,4.48) and 4.76 (2.21,10.27), respectively. The presence of EMVI was a significant predictor of decreased overall and disease-free survival (P<0.001). CONCLUSIONS: This study demonstrated, in the presence of high surgical, oncology and pathological standards, EMVI and increasing LNR were independent predictors of decreased overall and disease-free survival for patients undergoing curative colon cancer resection. LNR was superior to pN stage in predicting overall and disease-free survival.

AIM: The aim of this study was to compare the early postoperative outcome of patients undergoing laparoscopic subtotal colectomy with those undergoing open subtotal colectomy for colitis refractory to medical treatment. METHOD: A retrospective observational study was carried out of patients who underwent subtotal colectomy for refractory colitis, at a single centre, between 2006 and 2012. Patients were matched for age, gender, American Society of Anesthesiology (ASA) grade, urgency of operation and immunosuppressant/modulator treatment. The primary outcome measure was the number of postoperative complications, classified using the Clavien-Dindo scale. Secondary end-points included procedure duration, laparoscopic conversion rates, blood loss, 30-day readmission rates and length of hospital stay. RESULTS: Ninety-six patients were included, 39 of whom had laparoscopic surgery. Thirty-two of these were matched to similar patients who underwent an open procedure. The overall duration of the procedure was longer for laparoscopic surgery than for open surgery (median: 240 vs 150 min, P < 0.005) but estimated blood loss was less (median: 75 vs 400 ml, P < 0.005). In the laparoscopic group, 23 patients experienced 27 complications, and in the open surgery group, 23 patients experienced 30 complications. Most complications were minor (Grade I/II), and the distribution of complications, by grade, was similar between the two groups. There was no statistically significant difference in 30-day readmission rates between the laparoscopic and open groups (five readmissions vs eight readmissions, P = 0.536). Length of hospital stay was 4 days shorter for laparoscopic surgery, but this difference was not statistically significant (median: 7 vs 11 days, P = 0.159). CONCLUSION: In patients requiring colectomy for acute severe colitis, laparoscopic surgery reduced blood loss but increased operating time and was not associated with a reduction in early postoperative complications, length of hospital stay or readmission rates.

AIM: Assessment of the chest in colorectal cancer (CRC) staging is variable. The aim of this review was to look at different chest staging strategies and determine which has the greatest efficacy. METHOD: A review of studies assessing chest staging modalities for patients with CRC was performed. Modalities included chest X-ray (CXR), CT and positron emission tomography (PET). RESULTS: The majority of data consisted of case series. Two studies identified a low pick-up rate for CXR as a staging tool. Five studies showed increased detection rates of pulmonary metastases for chest CT vs CXR and abdominal CT. The clinical benefit of the increased detection rates was not clear. The incidence of indeterminate lung lesions (ILL) on staging chest CT varied from 4 to 42%. The majority (≥ 70%) of ILLs did not have any clinical significance. On CT scans, the incidence of pulmonary metastases in patients with rectal cancer ranged from 10 to 18% and in patients with colon cancer the incidence of pulmonary metastases ranged from 5-6%. The incidence of synchronous liver and pulmonary metastases compared with the overall incidence of pulmonary metastases ranged from 45 to 70%. There was no evidence reporting the superiority of PET/CT vs CT for the detection of pulmonary metastases or characterization of ILL. CONCLUSION: Studies show that chest CT scanning increases the detection rates for ILL and pulmonary metastases. The clinical benefit of the increased detection rates is not clear. There is a paucity of data assessing the optimal chest staging strategy for patients presenting with CRC.

AIM: End-stage renal failure (ESRF) and renal transplant recipients are thought to be associated with an increased risk of colorectal complications. METHOD: A review of the literature was performed to assess the prevalence and outcome in both benign and malignant colorectal disease. RESULTS: No prospective randomized studies assessing colorectal complications in ESRF or renal transplant were identified. Case series and case reports have described the incidence and management of benign colorectal complications. Complications included diverticulitis,infective colitis, colonic bleeding and colonic perforation. There was insufficient evidence to associated iverticular disease with adult polycystic kidney disease.Three population-based studies have shown up to a twofold increased incidence of colonic cancer but not rectal cancer for renal transplant recipients. Bowel cancer screening (as per the general population) by faecal occult blood testing appears justified for renal transplant patients; however, evidence suggests that consideration of starting screening at a younger age may be worthwhile because of an increased risk of developing colonic cancer.Two population-based studies have shown a threefold and 10-fold increased incidence of anal cancer for renal transplant recipients. A single casecontrol study demonstrated significant increased prevalence of anal human papilloma virus (HPV) and intraepithelial neoplasia (AIN)in patients with established renal transplants. CONCLUSIONS: Despite the lack of high-level evidence,ESRF and renal transplantation were associated with colorectal complications that could result in major morbidity and mortality. Bowel cancer screening in this patient group appears justified. The effectiveness of screening for HPV, AIN and anal cancer in renal transplant recipients remains unclear.

PURPOSE: Severe inflammatory colitis as a consequence of inflammatory bowel disease (IBD) may not be amenable to medical management, and surgery is often required. The optimal timing of surgery and perioperative therapeutic care requires a formal link between surgical department and gastroenterology which is often lacking. In this study, we assess the impact of adopting a multidisciplinary care bundle on complication rates of subtotal colectomy in IBD patients. METHODS: This is a single-centre retrospective observational study. Patients were identified through clinical discharge ICD10 codes. Clinical notes of patients who underwent subtotal colectomies from 1 January 2006 to 31 December 2019 were analysed. Socio-demographics, diagnosis, and medical and surgical management data were collected. A multimodule bundle, including weekly MDT discussions, was started in our unit on 1 April 2014. Multivariable logistic regression analysis was performed on these data. RESULTS: A total of 296 patients were identified with 113 patients of these (38.2%) experiencing a complication post operation. The overall complication rate improved over time (p = 0.023). Those patients treated after the initiation of the MDT bundle had reduced complication rates (44.6% versus 33.7%, p = 0.045). On multivariate analysis, increasing age (1.023 OR; 95% CI 1.004, 1.041) and procedure performed before MDT bundle (3.1 OR; 95% CI 1.689, 5.723) were independent predictors for post-operative complications. CONCLUSIONS: Closer links between gastroenterology and colorectal specialties have improved patient outcomes in our unit. Whilst IBD MDTs have previously been shown to improve outcomes for patients managed medically, we demonstrate that this interaction, implemented as a multidisciplinary care bundle, also improves surgical outcomes.

Cystic adventitial disease (CAD) is rare. The popliteal artery is the most commonly affected artery. Patients with CAD are usually young and present with ischaemic lower limb symptoms. We report a case of a 39-year-old male patient with popliteal CAD. The affected segment was resected and repaired with an interposition vein graft. In conclusion, we highlight the importance of correct diagnosis and outline the different management strategies.

BACKGROUND: Perioperative haemodynamic changes are well recognised sequelae of adrenalectomy for phaeochromocytomas. The aim of this study was to compare haemodynamic changes in patients undergoing laparoscopic adrenalectomy (LA) for phaeochromocytomas and other adrenal tumours. METHOD: Patients were identified from a prospective database (Jan 1999-Feb 2008). All patients were managed by a multi-disciplinary team. Haemodynamic variables were: pulse, blood pressure and the requirement of antihypertensive or vasopressor therapies in the perioperative period. RESULTS: Over the nine-year period, 34 consecutive patients underwent laparoscopic phaeochromocytoma resection (one patient had delayed contralateral LA) and 104 consecutive patients underwent LA for other tumours (two patients had delayed contralateral LA). 5 out of 35 resections in the phaeochromocytoma group experienced severe hypertension (systolic blood pressure (SBP) >200 mm Hg) compared to two out of 106 resections in the non phaeochromocytoma group (p=0.010). No patient in either group had a transient or persistent (>10 min) SBP >220 mm Hg. Intraoperative antihypertensive use was significantly increased in the phaeochromocytoma group (p<0.005). There were no significant differences between groups for persistent hypotension (SBP <80 mm Hg), heart rate >120/min and recovery room haemodynamic parameters. CONCLUSION: LA for phaeochromocytoma can be accomplished with low perioperative haemodynamic complications when compared to LA for other adrenal tumours.

OBJECTIVE: A literature search did not produce any evidence-based objective criteria to determine which patients with locally advanced rectal cancer would benefit from a defunctioning stoma prior to neoadjuvant chemoradiotherapy. Our criteria for formation of a defunctioning stoma are: faecal incontinence and inability to cannulate the tumour at colonoscopy. The aim of this study was to examine whether these current criteria are appropriate. METHOD: Forty-nine consecutive locally advanced rectal cancer patients treated from February 2003 to November 2006 were identified from our colorectal database. All received long-course chemoradiotherapy (Bossett regimen) and definitive surgery was performed 6-8 weeks later. RESULTS: Of the 49 patients, 31 presented with diarrhoea and two with faecal incontinence; nine patients were defunctioned by trephine stoma prior to treatment [cannulation impossible at colonoscopy (n = 8); faecal incontinence (n = 1)]. One patient with faecal incontinence refused early defunctioning stoma. Median hospital stay was 12 days (interquartile range: 7-30), and complications included pneumonia (n = 1) and peristomal cellulitis (n = 2). Of the 40 patients who went directly to neoadjuvant chemoradiotherapy, two subsequently required a defunctioning stoma for severe diarrhoeal symptoms during therapy. Eight patients had worsening diarrhoeal symptoms but tolerated treatment. Three patients, who had stoma formation, did not proceed to definitive surgery following neoadjuvant therapy: poor operative fitness (n = 2) and disease progression (n = 1). CONCLUSION: Stenosis causing inability to cannulate the tumour at colonoscopy and faecal incontinence were the only objective indications for an early defunctioning stoma. Worsening diarrhoea during therapy (unless severe) did not appear to be a good indication for a defunctioning stoma.

Lower limb venous disease encompasses a wide spectrum of pathology, the importance of which relates to high prevalence rather than mortality. The complications of chronic venous insufficiency (CVI), namely lipodermatosclerosis and chronic venous ulceration, represent a major burden to healthcare providers and a high degree of personal morbidity for patients. Management is based upon accurate clinical diagnosis supported by non-invasive imaging. Open surgical and minimally invasive techniques are used to treat varicose veins. Chronic skin complications of CVI require a multidisciplinary approach.

BACKGROUND: In patients with suspected pancreatico-biliary disease, endoscopic retrograde cholangiopancreatography (ERCP) should be reserved for those requiring therapeutic intervention. However, difficulty arises in identifying patients likely to require therapy in the early phase of diagnostic work-up. An algorithm has been developed by the authors based upon prospective assessment of ERCP patients for triage of patients to magnetic resonance cholangiopancreatography (MRCP) or ERCP with suspected pancreatico-biliary disease. We aimed to validate this algorithm in an independent group of patients using a different group of endoscopists blinded to the algorithm. METHODS: Patients were stratified into different categories by clinical, ultrasound and liver function test findings. The algorithm stratified patients by the likelihood of therapeutic intervention. The accuracy of the algorithm for a therapeutic outcome was assessed by receiver operator characteristics (ROC) curve analysis. RESULTS: Hundred and twenty-five consecutive patients (Oct 2005 to July 2006) were prospectively assessed by MRCP or ERCP according to the algorithm, and the outcomes recorded. Fifty-seven patients were triaged to MRCP and 63 patients were triaged to ERCP. A category was not assessable in five patients. Three patients from the MRCP group required subsequent therapeutic ERCP. Diagnostic ERCP was performed in three patients in the ERCP group. ERCP-related complications occurred in four patients. The algorithm performed well in predicting the requirement for intervention as determined by the area under the ROC curve [0.84 (95%CI 0.76-0.92)]. CONCLUSIONS: Our study confirms that an algorithm-based approach can reproducibly predict those patients requiring therapeutic biliary intervention.

BACKGROUND: Laparoscopic adrenalectomy (LA) has been shown to reduce hospital stay and morbidity when compared to open adrenalectomy (OA). It is uncertain if the laparoscopic resection of large (>/=6 cm) potentially malignant adrenal tumours is appropriate due to concern over incomplete resection and local recurrence. The aim of the present study was to compare the outcomes of LA for tumours >/=6 cm with those < 6 cm. METHODS: Details of all patients referred with adrenal tumours between January 1999 and January 2006 had been recorded prospectively on a database. LA was performed using a lateral transabdominal approach. Contraindications to LA were local invasion requiring en bloc resection of adjacent organs or the requirement of additional open procedures. RESULTS: 103 patients were referred for adrenal resection. Three with metastatic adrenal carcinoma and two with severe cardiorespiratory disease were deemed unsuitable for operation. One hundred and eleven adrenalectomies were performed: 101 LAs and 10 OAs. Thirty-nine LA were for tumours >/=6 cm while nine OA were for tumours >/=6 cm. There were no significant differences between the median total anaesthetic time, postoperative complications or postoperative stay for patients undergoing LA for tumours >/=6 cm versus tumours <6 cm. Of the six conversions, five were performed for adrenal tumours >/=6 cm [local invasion (n = 3), adhesions (n = 1), primary renal carcinoma (n = 1)]. All tumours in the LA group were resected with clear margins and at a median follow up of 50 months (range 38-74 months). There has been no evidence of local recurrence. CONCLUSIONS: In the absence of local invasion, the outcomes of laparoscopic adrenalectomy for patients with tumours >/=6 cm were comparable to those with tumours <6 cm. This has helped confirm a policy of initial laparoscopic resection for all noninvasive adrenal tumours can be applied safely.

INTRODUCTION: We report a case of IEA false aneurysm following a mesh repair of a large incisional hernia. We emphasize the importance to consider the diagnosis to help avoid inappropriate interventions which could increase patient morbidity. CASE REPORT: A 68-year-old male patient, who 4 weeks previously had had a mesh repair of a large incisional hernia, presented with a painful left iliac fossa swelling. This was found to be an IEA false aneurysm. This was treated successfully with percutaneous thrombin injection. CONCLUSIONS: We feel an inferior epigastric artery false aneurysm must be included in the differential diagnosis when investigating the cause of any lateral swelling following incisional hernia repair. This would help reduce the chance of a missed diagnosis and avoid any inappropriate interventions which may cause increased patient morbidity.
