RESUMO
It is generally recommended to refrain from taking rectal biopsies in radioproctopathy. Herein we describe the clinical characteristics of urorectal fistulas after such biopsies in five patients. Conservative treatment is rarely successful. Diagnostic difficulties and comorbidities limiting the possibilities for radical surgical treatment options (i e pelvic exenteration) for urorectal fistulas are discussed.

PURPOSE: To explore whether previous participation in clinical studies increases adherence to management guidelines in acute uncomplicated diverticulitis (AUD). METHODS: This retrospective cohort study was designed to give a SNAPSHOT of the management of AUD at six hospitals, three of which had participated in the AVOD trial comparing antibiotic versus non-antibiotic treatment of AUD. Patients with AUD were included from March 2019 through June 2020 and followed for 90 days. The primary outcome was treatment of AUD categorised by antibiotic treatment and inpatient or outpatient management compared between AVOD and non-AVOD hospitals. Descriptive statistics were compiled, and differences between hospitals were assessed with Pearson's chi-squared test. RESULTS: The cohort included 449 patients with AUD of which 63% were women and the median age was 63 (IQR: 52-73) years. Patient characteristics were comparable across the hospitals. Antibiotics were administered to 84 (19%) patients and 113 (25%) patients were managed as inpatients. Management varied significantly between AVOD and non-AVOD hospitals. The mean proportion of patients treated with antibiotics was 7% at AVOD hospitals compared to 38% at non-AVOD hospitals (p < 0.001). The mean proportion of in-hospital management was 18% at AVOD hospitals versus 38% at non-AVOD hospitals (p < 0.001). CONCLUSION: Most patients with AUD were managed according to current guidelines. However, the management varies between hospitals and previous participation in clinical studies may increase knowledge of and adherence to guidelines.

BACKGROUND: The quality of the total mesorectal excision specimen in rectal cancer surgery is assessed with a three-tier grade (mesorectal, intramesorectal and muscularis propria). This study aimed to analyse the prognostic impact of the total mesorectal excision grade on survival, and to identify risk factors for intramesorectal and muscularis propria resection in a population-based setting. METHODS: All patients in the Swedish Colorectal Cancer Registry with rectal cancer stage I-III ≤ 10 cm from the anal verge, diagnosed 2015-2019, undergoing total mesorectal excision were analysed. Clinical, surgical and pathological data were retrieved and analysed for the following primary outcomes: local and distant recurrence and overall and relative survival; secondary outcomes were risk factors for total mesorectal excision grading (intramesorectal or muscularis propria resection). Of note, postoperative death < 30 days or recurrence within 90 days were exclusion criteria for survival and recurrence analysis. Recurrence-free patients with less than 3 years follow-up, and patients lacking data regarding recurrence, were also excluded from recurrence analyses. RESULTS: Overall, of 7979 patients treated during the study interval, 1499 patients were eligible for recurrence, 2441 patients for survival and 2476 patients for risk-factor analyses, of which 75% were graded mesorectal, 17% intramesorectal and 8% muscularis propria. Median follow-up for survival was 42 (1-77) months. The worst total mesorectal excision grading (muscularis propria resection) was an independent risk factor for local recurrence in multivariable analysis (HR 2.73, 95% c.i. 1.07 to 7.0, P = 0.036). Total mesorectal excision grade had no impact on distant recurrence or survival. Female sex, tumour level <5 cm, abdominoperineal resection, minimally invasive surgery (laparoscopic and robotic), high blood loss, long duration of surgery and intraoperative perforation were independent risk factors for worse total mesorectal excision grading (intramesorectal and/or muscularis propria resection) in multivariable analyses. CONCLUSION: Muscularis propria resection increases the risk of local recurrence but does not seem to affect distant recurrence or survival.

AIM: The incidence of colorectal cancer (CRC) in Sweden is increasing in individuals <50 years. This study aimed to examine differences in postoperative 30-day complications and rate of emergency surgeries in CRC patients <50 years at diagnosis compared to older age groups since population-based research on this topic is scarce. METHOD: This population-based study included data from the Swedish Colorectal Cancer Registry for patients undergoing CRC resection between 2010 and 2018. Bivariate analysis and logistic regression were used to analyse the relationship between age groups (<50, 50-79 and ≥80 years) and probability of postoperative 30-day complications adjusted for gender, tumour localization, neoadjuvant (chemo)radiotherapy and American Society of Anesthesiologists score. RESULTS: In total 33 320 patients were included. Patients <50 years had a lower American Society of Anesthesiologists score, more advanced tumours and received more neoadjuvant treatment. Emergency surgeries were less common in the youngest age group (P < 0.001) as well as overall postoperative 30-day complications: ORadj 0.84 (95% CI 0.74-0.96) compared to those ≥80 years. Surgical complications were more common in age groups <50 and 50-79 years (16.5% and 16.9% respectively) compared to patients ≥80 years (14.1%) (P < 0.001). Anastomotic leakage and intra-abdominal infections were more frequent in patients <50 years (5.7% and 3.5% respectively) compared to age groups 50-79 years (5.1% and 2.8% respectively) and ≥80 years (3.5% and 2.1% respectively) (P < 0.001). Wound infections were more common in the two youngest age groups compared to patients ≥80 years (5.3% vs. 3.7% respectively) (P < 0.001). CONCLUSION: Colorectal cancer patients <50 years and 50-79 years had a higher proportion of surgical complications regarding anastomotic leakage, intra-abdominal infections and wound infections but lower overall postoperative complications. The incidence of surgical emergencies was highest amongst patients ≥80 years. Postoperative diagnostic workup in symptomatic individuals <50 years is warranted.

BACKGROUND/AIM: Anterior resection is the gold standard surgery for high and middle rectal tumors. In cases where anterior resection is not feasible, the surgeon resorts to a non-restorative approach such as Hartmann's procedure or abdominoperineal resection. It is not well studied how Hartmann's procedure impacts quality of life. This cross-sectional cohort study compares the long-term quality of life after Hartmann's procedure with anterior resection and abdominoperineal resection. PATIENTS AND METHODS: Patients operated for high- or middle rectal cancer in the southern healthcare region of Sweden between 2007 and 2017 were identified and data were extracted from the Swedish Colorectal Cancer Registry. Further clinical variables were retrieved from medical charts. Quality of life was evaluated by SF-12-, EQ-5D-5L- and EORTC QLQ - CR29 questionnaires. RESULTS: Out of 521 patients included, 51 had undergone Hartmann's procedure, 381 anterior resection and 89 abdominoperineal resection. Hartmann patients were significantly older with more comorbidities. Median follow-up time was 104 months. There were no differences between groups in overall quality of life. Patients subjected to Hartmann's procedure reported inferior mobility, self-care, daily activities and reduced estimation of general health compared to those who had anterior resection. Abdominoperineal resection was associated with more impotence compared to Hartmann's procedure. CONCLUSION: Overall long-term QoL after Hartmann's procedure was comparable to anterior resection and abdominoperineal resection. In certain symptoms patients with Hartmann's procedure for rectal cancer scored worse compared to anterior resection, but patients were older and frailer making causal inference impossible.

BACKGROUND: Rectal cancer patients commonly benefit from neoadjuvant therapy before resection surgery. For these patients, an elective ostomy diversion is frequently considered, despite the absence of conclusive evidence when a diversion is advantageous. This is a retrospective observational single-center study on a 4-year consecutive rectal cancer cohort undergoing neoadjuvant therapy, aiming at improving the understanding of risks and benefits associated with ostomy diversion. MATERIAL AND METHOD: Baseline characteristics, tumor-specific data, clinical events, and outcomes were collected using the Swedish Colorectal Cancer Registry and medical records. RESULTS: Thirty-two (30.2%) of the 106 included patients presented with endoscopic impassable tumors at diagnosis, of which 18 (56.2%) had diverting ostomy. Three out of 14 with impassable tumor and no diversion developed a bowel obstruction. None of the patients with an endoscopically passable tumor at diagnosis (n = 74) experienced a bowel obstruction. The elective diversions (n = 40) were not associated with serious complications (Clavien-Dindo grade ⩾ 3b). Patients with a diverting ostomy (n = 30) had similar time intervals from diagnosis to neoadjuvant treatment and to definite tumor resection as those without diversion but experienced more complex primary tumor resections in terms of blood loss and operation time. CONCLUSION: An elective diverting ostomy is a relatively safe procedure in rectal cancer patients requiring neoadjuvant therapy. More than one out of five non-diverted patients with endoscopically impassable rectal tumors developed bowel obstruction and would potentially have benefited from an elective diversion.
RESUMO
INTRODUCTION: Conservative treatment of acute appendicitis is gaining popularity, and identifying patients with a higher risk of recurrence is becoming increasingly important. Previous studies have suggested that older age, male sex, diabetes, appendicolith and abscess formation may be contributing factors, however, results from the adult population are inconsistent. AIM: This study aims to identify predictive factors for recurrent appendicitis after conservative treatment. METHODS: This retrospective study included patients with conservatively treated acute appendicitis at Skåne University Hospital, Sweden during 2012-2019. Information on patient demographics at index admission and follow-up data were retrieved from medical charts and radiologic images. Uni -and multivariable logistic regression analysis were performed using Stata Statistical Software. RESULTS: In total, 379 patients with conservatively treated acute appendicitis were identified, of which 78 (20.6%) had recurrence. All patients were followed-up for a minimum of 41 months after the first diagnosis of acute appendicitis unless appendectomy after successful conservative treatment or death occurred during follow-up. The median time to recurrence was 6.5 (1-17.8) months. After multivariable logistic regression analysis, external appendix diameter >10 mm [OR 2.4 (CI 1.37-4.21), p = .002] and intra-abdominal abscess [OR 2.05 (CI 1.18-3.56), p = .011] on computed tomography were significant independent risk factors for recurrent appendicitis. Appendicolith was not associated with an increased risk of recurrence. CONCLUSION: This study suggests abscess formation and appendix distension of >10 mm to be potential risk factors for recurrent acute appendicitis after initial successful conservative treatment.

BACKGROUND: Resection margin has been associated with overall survival following liver resection for colorectal liver metastasis. The aim of this study was to examine how resection margins of 0.0â mm, 0.1-0.9â mm and ≥1â mm influence overall survival in patients resected for colorectal liver metastasis in a time of modern perioperative chemotherapy and surgery. METHODS: Using data from the national registries Swedish Colorectal Cancer Registry and Swedish National Quality Registry for Liver, Bile Duct and Gallbladder Cancer, patients that had liver resections for colorectal liver metastasis between 2009 and 2013 were included. In patients with a narrow or unknown surgical margin the original pathological reports were re-reviewed. Factors influencing overall survival were analysed using a Cox proportional hazard model. RESULTS: A total of 754 patients had a known margin status, of which 133 (17.6%) patients had a resection margin <1â mm. The overall survival in patients with a margin of 0â mm or 0.1-0.9â mm was 42 (95% c.i. 31 to 53) and 48 (95% c.i. 35 to 62) months respectively, compared with 75 (95% c.i. 65 to 85) for patients with ≥1â mm margin, P < 0.001. Margins of 0â mm or 0.1-0.9â mm were associated with poor overall survival in the multivariable analysis, HR 1.413 (95% c.i. 1.030 to 1.939), P = 0.032, and 1.399 (95% c.i. 1.025 to 1.910), P = 0.034, respectively. CONCLUSIONS: Despite modern chemotherapy the resection margin is still an important factor for the survival of patients resected for colorectal liver metastasis, and a margin of ≥1â mm is needed to achieve the best possible outcome.

AIM: There is ongoing controversy regarding the extent to which Hartmann's procedure (HP) should be used in rectal cancer treatment. This study was designed to investigate 30-day postoperative morbidity and mortality following HP, anterior resection (AR) and abdominoperineal resection (APR) for rectal cancer using a national registry. METHODS: All patients operated for rectal cancer, tumour height 5-15 cm, between the years 2010 and 2017, were identified through the Swedish colorectal cancer registry. RESULTS: A total of 8476 patients were included: 1210 (14%) undergoing HP, 5406 (64%) AR and 1860 (22%) APR. HP was associated with an increased risk of intra-abdominal infection (OR 1.7, CI 1.26-2.28, P = 0.0004) compared to AR and APR, while APR was related to an increased risk of overall complications (OR 1.18, CI 1.01-1.40, P = 0.040). No significant difference was observed in the rate of reoperations and readmissions between HP, AR and APR, and type of surgical procedure was not a risk factor for 30-day mortality. Findings from a subgroup analysis of patients with a tumour 5-7 cm from the anal verge revealed that HP was not associated with increased risk for complications or 30-day mortality. CONCLUSIONS: For patients where AR is not appropriate HP is a valid alternative with a favourable outcome. APR was associated with the highest overall 30-day complication rate.

PURPOSE: Anastomotic leakage after anterior resection for rectal cancer induces bowel dysfunction, but the influence on urinary and sexual function is largely unknown. This cross-sectional cohort study evaluated long-term effect of anastomotic leakage on urinary and sexual function in male patients. METHODS: Patients operated with anterior resection for rectal cancer in 15 Swedish hospitals 2007-2013 were identified. Anastomotic leakage and other clinical variables were retrieved from the Swedish Colorectal Cancer Registry and medical records. Urinary and sexual dysfunction were evaluated at 4 to 11 years after surgery using the International Prostate Symptom Score, International Index of Erectile Function, and European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire CR29. The effect of anastomotic leakage on average scores of urinary and sexual dysfunction was evaluated as a primary outcome, and the single items permanent urinary catheter and sexual inactivity as secondary outcomes. The association of anastomotic leakage and functional outcomes was analyzed using regression models with adjustment for confounders. RESULTS: After a median follow-up of 84 months (interquartile range: 67-110), 379 out of 864 eligible men were included. Fifty-nine (16%) patients had anastomotic leakage. Urinary incontinence was more common in the leakage group, with an adjusted mean score difference measured by EORTC QLQ ColoRectal-29 of 8.69 (95% confidence interval: 0.72-16.67). The higher risks of urinary frequency, permanent urinary catheter, and sexual inactivity did not reach significance. CONCLUSION: Anastomotic leakage after anterior resection had a minor negative impact on urinary and sexual function in men.

PURPOSE: This study aimed to investigate patient-related factors predicting the selection of rectal cancer patients to Hartmann's procedure as well as to investigate how often, and on what grounds, anterior resection is intraoperatively changed to Hartmann's procedure. METHODS: Prospectively collected data from the Swedish Colorectal Cancer Registry regarding patients with rectal cancer operated upon from January 1 2007 to June 30 2017 in the county of Skåne were retrospectively reviewed. Data were expanded with further details from medical charts. A univariable analysis was performed to investigate variables associated with unplanned HP and significant variables included in a multivariable logistic regression analysis. RESULTS: Altogether, 1141 patients who underwent Hartmann's procedure (275 patients, 24%), anterior resection (491 patients, 43%), or abdominoperineal resection (375 patients, 33%) were included. Patients undergoing Hartmann's procedure were significantly older and had more frequently comorbidity. The decision to perform Hartmann's procedure was made preoperatively in 209 (76%) patients, most commonly because of a comorbidity (27%) or oncological reasons (25%). Patient preference was noted in 8% of cases. In 64 cases (23%), the decision was made intraoperatively, most often due to anastomotic difficulties (60%) and oncological reasons (22%). Anastomotic difficulties were most often reported due to technical difficulties, a low tumor or neoadjuvant radiotherapy. Male gender was a significant risk factor for undergoing unplanned Hartmann's procedure. CONCLUSIONS: The decision to perform Hartmann's procedure was frequently made intraoperatively. Hartmann's procedure should be considered and discussed preoperatively in old and frail patients, especially in the presence of mid-rectal cancer and/or male gender, since these factors increase the risk of intraoperative anastomotic difficulties.

BACKGROUND AND OBJECTIVE: Defunctioning loop ileostomy (DLI) is frequently used to decrease the consequences of anastomotic leak after ileal pouch-anal anastomosis (IPAA) surgery but is controversial because of stoma-associated morbidity. The aim of this study was to describe stoma-associated morbidity in IPAA-DLI patients compared with terminal ileostomy patients. METHODS: Patients treated with colectomy for inflammatory bowel disease at Skåne University Hospital, Sweden, between 2005 and 2021 were eligible for inclusion. Terminal stoma-related morbidity was measured until 12 months after colectomy, IPAA surgery, or conversion to ileorectal anastomosis, whichever occurred first. DLI-related morbidity was measured until 12 months after IPAA surgery or stoma closure, whichever occurred first. Laboratory data were reviewed up to 18 months after surgery since patients without complications were rarely subjected to blood sampling. Data on patient characteristics, renal function, surgical complications, and readmissions were collected retrospectively. Primary outcomes were DLI- and terminal ileostomy-related renal morbidity, whereas secondary outcomes focused on stoma-related complications. RESULTS: The study cohort consisted of 165 patients with terminal ileostomy after colectomy (median (interquartile range (IQR)): stoma time 30 (15-74) months) and 42 patients with IPAA-DLI (median (IQR): stoma time 4 (3-5) months). One case of anastomotic IPAA leakage was observed. IPAA-DLI patients more often required hospital care due to high-volume stoma output immediately after surgery (0-30 days, 29%) compared with terminal ileostomy patients (4%, p < 0.001). There were no significant differences in acute renal injury (p = 0.073) or chronic renal failure (p = 0.936) incidences between the groups. DLI closure was achieved in 95% of IPAA-DLI patients, with 5% suffering Clavien-Dindo complications > 2. CONCLUSIONS: IPAA-DLI patients exhibited higher incidence of short-term high-volume stoma output without higher rates of acute renal injury or chronic renal failure compared with terminal ileostomy patients in this small single-center retrospective study suggesting that the risk of renal morbidity in IPAA-DLI patients may have been overestimated.
RESUMO
OBJECTIVES: Pre-treatment staging of anal squamous cell carcinoma (ASCC) includes pelvic MRI and [18F]-fluorodeoxyglucose positron emission tomography with computed tomography (PET-CT). MRI criteria to define lymph node metastases (LNMs) in ASCC are currently lacking. The aim of this study was to describe the morphological characteristics of lymph nodes (LNs) on MRI in ASCC patients with PET-CT-positive LNs. METHODS: ASCC patients treated at Skåne University Hospital between 2009 and 2017 were eligible for inclusion if at least one positive LN according to PET-CT and a pre-treatment MRI were present. All PET-CT-positive LNs and PET-CT-negative LNs were retrospectively identified on baseline MRI. Each LN was independently classified according to pre-determined morphological characteristics by two radiologists blinded to clinical patient information. RESULTS: Sixty-seven ASCC patients were included, with a total of 181 PET-CT-positive LNs identified on baseline MRI with a median short-axis diameter of 9.0 mm (range 7.5-12 mm). MRI morphological characteristics of PET-CT-positive LNs included regular contour (87%), round shape (89%), and homogeneous signal intensity on T2-weighed images (67%). An additional 78 PET-CT-negative LNs were identified on MRI. These 78 LNs had a median size of 6.8 mm (range 5.5-8.0 mm). The majority of PET-CT-negative LNs had a regular contour, round shape, and a homogeneous signal that was congruent to the primary tumor. CONCLUSIONS: There are MRI-specific morphological characteristics for pelvic LNs in ASCC. PET-CT-positive and negative LNs share similar morphological features apart from size, with PET-CT-positive LNs being significantly larger. Further studies are needed to determine discrimination criteria for LNM in ASCC.

BACKGROUND: Diverticulosis is a common condition and is thought to be increasing in the Western population. Several studies have attempted to estimate the prevalence of diverticulosis and it's inflamed state, diverticulitis, with results varying depending on study population and methodology, The aim of this study was to investigate the prevalence of diverticulosis in patients undergoing colonoscopy at a Swedish academic referral centre and to study the incidence of diverticulitis in a 10-year follow-up. METHODS: All patients who had undergone colonoscopy at the Endoscopy unit, Skåne University Hospital, Sweden, during 01 January 2010 through 31 December 2011 were identified. The colonoscopy referrals, colonoscopy reports, and medical records until 14 June 2022 were reviewed. RESULTS: In all, 2648 patients were included in the study, whereof 910 patients had reported diverticulosis (34.4%). During the 10-year follow-up, the overall incidence of computed tomography verified diverticulitis was 4.4%, and 0.6% for patients with and without diverticulosis at index colonoscopy, respectively. Of the 50 patients that developed diverticulitis, 21 were complicated and 29 uncomplicated. CONCLUSION: Diverticulosis is a common condition in the population, although most patients will not develop diverticulitis.

BACKGROUND: Tumour deposits are suggested to impact prognosis in colon cancer negatively. This study assessed the impact of tumour deposits on oncological outcomes. METHODS: Data from the Swedish Colorectal Cancer Registry for patients who underwent R0 abdominal surgery for TNM stage I-III colon cancer between 2011 and 2014 with 5-year follow-up were analysed with multivariable analysis. Patients were categorized for their tumour deposit status and compared for the local recurrence and distant metastasis rates and 5-year survivals (overall and relative). Subgroup analyses were performed according to the nodal disease status. RESULTS: Of 8146 stage I-III colon cancer patients who underwent R0 resection, 8014 patients were analysed (808 tumour deposits positive, 7206 tumour deposits negative). Patients with tumour deposits positive tumours had increased local recurrence and distant metastasis rates (7.2 versus 3.0 per cent; P < 0.001 and 33.9 versus 12.0 per cent; P < 0.001 respectively) and reduced 5-year overall and relative survival (56.8 per cent versus 74.9 per cent; P < 0.001 and 68.5 versus 92.6 per cent; P < 0.001 respectively). In multivariable analysis, tumour deposits moderately increased the risks of local recurrence and distant metastasis (hazard ratio 1.50, 95 per cent c.i. 1.09 to 2.07; P = 0.013 and HR 1.91, 95 per cent c.i. 1.64 to 2.23; P < 0.001 respectively) and worse 5-year overall and relative survival (hazard ratio 1.60, 95 per cent c.i. 1.40 to 1.82; P < 0.001 and excess hazard ratio 2.24, 95 per cent c.i. 1.81 to 2.78; P < 0.001 respectively). Subgroup analysis of N stages found that N1c patients had worse outcomes than N0 for distant metastasis and relative survival. For patients with lymph node metastases tumour deposits increased the risks of distant metastasis and worse overall and relative survival, except for N2b patients. CONCLUSION: Tumour deposits negatively impact the prognosis in colon cancer and must be considered when discussing adjuvant chemotherapy.

Resection of advanced rectal cancer might result in significant tissue loss, including pelvic floor and parts of the vaginal wall. Pelvic floor reconstruction using a musculocutaneous flap offers optimized healing abilities and the possibility of vaginal reconstruction. In Skåne University Hospital, two different flap techniques are used to reconstruct the perineum: the vertical rectus abdominis musculocutaneous flap and the gluteus maximus (GM) flap. A combination of a GM flap and a fasciocutanous flap, referred to locally as a GM special (GMS) flap, is used for posterior vaginal wall reconstruction in women undergoing abdominoperineal resections including parts of or the total posterior vaginal wall. The GMS flap was introduced through a national collaboration in Sweden in 2013. The aim of this article is to offer a detailed description and illustrations of the surgical technique used to construct the GMS flap, focusing on the posterior vaginal wall reconstruction. In our experience, the GMS flap is a resilient and cosmetically appealing choice that is technically easily harvested. The flap has acceptable morbidity and long-term results with adequate neovaginal measurements. Collaborative work is further encouraged.
RESUMO
BACKGROUND AND AIMS: Appendectomy has historically been the standard treatment of acute appendicitis, but lately, conservative treatment of uncomplicated acute appendicitis with antibiotics has successfully been used in selected patients. Complicated acute appendicitis is often treated conservatively initially, but may benefit from interval appendectomy due to the higher risk of appendiceal malignancy and recurrence. Recommendations for follow-up after conservatively treated appendicitis vary. Furthermore, the risk of underlying malignancy and the necessity of routine interval appendectomy are unclear. This study aims to evaluate follow-up status, recurrence, and underlying appendiceal malignancy in conservatively treated uncomplicated and complicated acute appendicitis. METHODS: This study included patients with conservatively treated acute appendicitis at Skåne University Hospital, Sweden during 2012-2019. Information on patient demographics at index admission and data on follow-up, recurrence, number of appendectomies after initial conservative treatment, and underlying malignancy were retrieved from medical charts. RESULTS: The study cohort included 391 patients, 152 with uncomplicated and 239 with complicated acute appendicitis. Median time of study follow-up was 52 months. The recurrence risk was 23 (15.1%) after uncomplicated and 58 (24.3%) after complicated acute appendicitis (p = 0.030). During follow-up, 55 (23%) patients with complicated acute appendicitis underwent appendectomy. Appendiceal malignancies were found in 12 (5%) patients with previous complicated acute appendicitis versus no appendiceal malignancies after uncomplicated acute appendicitis (p = 0.002). CONCLUSION: The risk of appendiceal malignancy and recurrent appendicitis was significantly higher in patients with complicated acute appendicitis compared with uncomplicated acute appendicitis.

BACKGROUND: Contemporary management of patients with synchronous colorectal cancer and liver metastases is complex. The aim of this project was to provide a practical framework for care of patients with synchronous colorectal cancer and liver metastases with a focus on terminology, diagnosis and management. METHODS: This project was a multi-organisational, multidisciplinary consensus. The consensus group produced statements which focused on terminology, diagnosis and management. Statements were refined during an online Delphi process and those with 70% agreement or above were reviewed at a final meeting. Iterations of the report were shared by electronic mail to arrive at a final agreed document comprising twelve key statements. RESULTS: Synchronous liver metastases are those detected at the time of presentation of the primary tumour. The term "early metachronous metastases" applies to those absent at presentation but detected within 12 months of diagnosis of the primary tumour with "late metachronous metastases" applied to those detected after 12 months. Disappearing metastases applies to lesions which are no longer detectable on MR scan after systemic chemotherapy. Guidance was provided on the recommended composition of tumour boards and clinical assessment in emergency and elective settings. The consensus focused on treatment pathways including systemic chemotherapy, synchronous surgery and the staged approach with either colorectal or liver-directed surgery as first step. Management of pulmonary metastases and the role of minimally invasive surgery was discussed. CONCLUSIONS: The recommendations of this contemporary consensus provide information of practical value to clinicians managing patients with synchronous colorectal cancer and liver metastases.
