RESUMEN
BACKGROUND: The timing and degree of implementation of minimally invasive surgery (MIS) for colorectal cancer vary among countries. Insights in national differences regarding implementation of new surgical techniques and the effect on postoperative outcomes are important for quality assurance, can show potential areas for country-specific improvement, and might be illustrative and supportive for similar implementation programs in other countries. Therefore, this study aimed to evaluate differences in patient selection, applied techniques, and results of minimal invasive surgery for colorectal cancer between the Netherlands and Sweden. METHODS: Patients who underwent elective minimally invasive surgery for T1-3 colon or rectal cancer (2012-2018) registered in the Dutch ColoRectal Audit or Swedish ColoRectal Cancer Registry were included. Time trends in the application of MIS were determined. Outcomes were compared for time periods with a similar level of MIS implementation (Netherlands 2012-2013 versus Sweden 2017-2018). Multilevel analyses were performed to identify factors associated with adverse short-term outcomes. RESULTS: A total of 46,095 Dutch and 8,819 Swedish patients undergoing MIS for colorectal cancer were included. In Sweden, MIS implementation was approximately 5 years later than in the Netherlands, with more robotic surgery and lower volumes per hospital. Although conversion rates were higher in Sweden, oncological and surgical outcomes were comparable. MIS in the Netherlands for the years 2012-2013 resulted in a higher reoperation rate for colon cancer and a higher readmission rate but lower non-surgical complication rates for rectal cancer if compared with MIS in Sweden during 2017-2018. CONCLUSION: This study showed that the implementation of MIS for colorectal cancer occurred later in Sweden than the Netherlands, with comparable outcomes despite lower volumes. Our study demonstrates that new surgical techniques can be implemented at a national level in a controlled and safe way, with thorough quality assurance.

BACKGROUND: A permanent stoma after anterior resection for rectal cancer is common. Preoperative counselling could be improved by providing individualized accurate prediction modelling. METHODS: Patients who underwent anterior resection between 2007 and 2015 were identified from the Swedish Colorectal Cancer Registry. National Patient Registry data were added to determine presence of a stoma 2 years after surgery. A training set based on the years 2007-2013 was employed in an ensemble of prediction models. Judged by the area under the receiving operating characteristic curve (AUROC), data from the years 2014-2015 were used to evaluate the predictive ability of all models. The best performing model was subsequently implemented in typical clinical scenarios and in an online calculator to predict the permanent stoma risk. RESULTS: Patients in the training set (n = 3512) and the test set (n = 1136) had similar permanent stoma rates (13.6 and 15.2 per cent). The logistic regression model with a forward/backward procedure was the most parsimonious among several similarly performing models (AUROC 0.67, 95 per cent c.i. 0.63 to 0.72). Key predictors included co-morbidity, local tumour category, presence of metastasis, neoadjuvant therapy, defunctioning stoma use, tumour height, and hospital volume; the interaction between age and metastasis was also predictive. CONCLUSION: Using routinely available preoperative data, the stoma outcome at 2 years after anterior resection for rectal cancer can be predicted fairly accurately.
Usually, the goal of rectal cancer surgery is to remove the tumour and construct a bowel join. Sometimes, it is necessary to construct a stoma, which may become permanent. Swedish registry data were used to develop and test a statistical model to forecast the risk of a stoma 2 years after surgery. In addition, an online calculator was developed. The model performed reasonably well, and can be used to inform the patient and surgeon before surgery of the risk of a permanent stoma.

BACKGROUND: Despite advances in perioperative care, the postoperative mortality rate after emergency oncological colonic resection remains high. Risk stratification may allow targeted perioperative optimization and cardiac risk stratification. This study aimed to test the hypothesis that the Revised Cardiac Risk Index (RCRI), a user-friendly tool, could identify patients who would benefit most from perioperative cardiac risk mitigation. METHODS: Patients who underwent emergency resection for colonic cancer from 2007 to 2017 and registered in the Swedish Colorectal Cancer Registry (SCRCR) were analysed retrospectively. These patients were cross-referenced by social security number to the Swedish National Board of Health and Welfare data set, a government registry of mortality, and co-morbidity data. RCRI scores were calculated for each patient and correlated with 90-day postoperative mortality risk, using Poisson regression with robust error of variance. RESULTS: Some 5703 patients met the study inclusion criteria. A linear increase in crude 90-day postoperative mortality was detected with increasing RCRI score (37.3 versus 11.3 per cent for RCRI 4 or more versus RCRI 1; P < 0.001). The adjusted 90-day all-cause mortality risk was also significantly increased (RCRI 4 or more versus RCRI 1: adjusted incidence rate ratio 2.07, 95 per cent c.i. 1.49 to 2.89; P < 0.001). CONCLUSION: This study documented an association between increasing cardiac risk and 90-day postoperative mortality. Those undergoing emergency colorectal surgery for cancer with a raised RCRI score should be considered high-risk patients who would most likely benefit from enhanced postoperative monitoring and critical care expertise.

BACKGROUND AND AIMS: Emergency laparotomy is associated with a great risk of mortality in the elderly. The hyperadrenergic state induced by surgical trauma may play an important role in the pathophysiology of this increased risk. Studies have shown that beta-blocker exposure may be associated with decreased morbidity and mortality in the perioperative period. We aimed to study the effect of beta-blocker on mortality in geriatric patients undergoing emergency laparotomy. MATERIAL AND METHODS: This is a retrospective study of patients who underwent emergency laparotomy between 1 January 2015 and 31 December 2016 at a single institution. The outcomes of interest were the association between post-operative complications and in-hospital and 1-year mortality in patients on beta-blocker therapy (BB(+)) and those who were not (BB(-)). The Poisson regression analysis was used to evaluate the association. RESULTS: A total of 192 patients were included of whom 62 (32.2%) had pre-operative beta-blocker therapy with continued exposure during their hospital stay. The in-hospital mortality was 17.7% in the BB(+) and 23.8% in the BB(-) cohorts (p = 0.441). One-year mortality was significantly lower in the BB(+) group compared to the BB(-) group (30.6% versus 47.7%; p = 0.038). After adjusting for confounders, the incidence of deaths during 1 year post-operatively decreased by 35% in the BB(+) group (incidence rate ratio = 0.65, p = 0.004). No significant differences in the incidence of post-operative complications between the two groups could be measured. CONCLUSION: Beta-blocker therapy may be associated with reduced 1-year mortality following emergency laparotomy in geriatric patients.

AIM: Low anterior resection of the rectum for cancer (LAR) entails a risk of symptomatic anastomotic leakage as well as impaired anorectal function, both of which may eventually result in the need for a permanent stoma (PS). The aim was to investigate the incidence of and risk factors for PS beyond 5 years following LAR. METHODS: Patients undergoing LAR and included in a multicentre trial with randomization to defunctioning stoma or not were followed for a median of 15 years. The reasons for a PS up to 5 years (PS ≤ 5 years) and beyond 5 years (PS > 5 years) were identified and compared. Risk factors for PS were analysed. RESULTS: Of all patients, 25% (57/232) had a PS. PS ≤ 5 years occurred in 19% (44/232) at a median of 12.5 months and PS > 5 years in 6% (13/232) at a median of 118 months following LAR. The main reason for PS ≤ 5 years was impaired anorectal function in 55% (24/44) and the main reason for PS > 5 years was pelvic sepsis related to the colorectal anastomosis in 46% (6/13). The major risk factor for PS was symptomatic anastomotic leakage, which occurred in 56% (32/57) of patients with PS and 10% (17/175) of patients without PS (P < 0.001). CONCLUSION: One-fourth of the patients who ended up with a PS had it fashioned beyond 5 years at a median of 10 years following LAR. Symptomatic anastomotic leakage was the major risk factor for PS, and impaired anorectal function was the main overall reason for a PS.

AIM: Low anterior resection syndrome (LARS) is common after low anterior resection. Our aim was to evaluate the prevalence and 'bother' (subjective, symptom-associated distress) of major LARS after 1 and 2 years, identify possible risk factors and relate the bowel function to a reference population. METHOD: The QoLiRECT (Quality of Life in RECTal cancer) study is a Scandinavian prospective multicentre study including 1248 patients with rectal cancer, of whom 552 had an anterior resection. Patient questionnaires were distributed at diagnosis and after 1, 2 and 5 years. Data from the baseline and at 1- and 2-year follow-up were included in this study. RESULTS: The LARS score was calculated for 309 patients at 1 year and 334 patients at 2 years. Prevalence was assessed by a generalized linear mixed effects model. Major LARS was found in 63% at 1 year and 56% at 2 years. Bother was evident in 55% at 1 year, decreasing to 46% at 2 years. Major LARS was most common among younger women (69%). Among younger patients, only marginal improvement was seen over time (63-59%), for older patients there was more improvement (62-52%). In the reference population, the highest prevalence of major LARS-like symptoms was noted in older women (12%). Preoperative radiotherapy, defunctioning stoma and tumour height were found to be associated with major LARS. CONCLUSION: Major LARS is common and possibly persistent over time. Younger patients, especially women, are more affected, and perhaps these patients should be prioritized for early stoma closure to improve the chance of a more normal bowel function.

AIM: Patients with rectal cancer often experience sexual dysfunction after treatment. The aim of this study was to evaluate sexual function in a prospective cohort of patients regardless of treatment and tumour stage and explore what factors might affect sexual activity 1 year after diagnosis. METHOD: The QoLiRECT study (Quality of Life in RECTal cancer) is a prospective study on the health-related quality of life in patients with rectal cancer in Denmark and Sweden. Questionnaires were completed at diagnosis and 1 year. Clinical data were retrieved from national quality registries. RESULTS: Questionnaire data were available from 1085 patients at diagnosis and 920 patients at 1 year. Median age was 69 years (range 25-100). At diagnosis, 29% of the women and 41% of the men were sexually active, which was lower than an age-matched reference population. This was further reduced to 25% and 34% at 1 year. Risk factors for sexual inactivity were absence of sexual activity prior to the diagnosis and the presence of a stoma. Women experienced reduced lubrication and more dyspareunia at 1 year compared with the time of diagnosis. In men, erectile dysfunction increased from 46% to 55% at 1 year. CONCLUSION: Sexual activity in patients with rectal cancer is lower at diagnosis compared with the population norm and is further reduced at 1 year. The presence of a stoma contributed to reduced sexual activity after operation. Sexual dysfunction was difficult to evaluate due to low sexual activity in the cohort. In men, erectile dysfunction is common.

AIM: The incidence of mesenteric ischaemia after resection for rectal cancer has not been investigated in a population-based setting. The use of high ligation of the inferior mesenteric artery might cause such ischaemia, as the bowel left in situ depends on collateral blood supply after a high tie. METHOD: The Swedish Colorectal Cancer Registry was used to identify all patients subjected to an abdominal resection for rectal cancer during the years 2007-2017 inclusive. Mesenteric ischaemia within the first 30 postoperative days was recorded, classified as either stoma necrosis or colonic necrosis. Multivariable logistic regression was used to estimate odds ratios (ORs) with 95% confidence intervals (CIs) for mesenteric ischaemia in relation to high tie, with adjustment for confounding. RESULTS: Some 14 657 patients were included, of whom 59 (0.40%) had a reoperation for any type of mesenteric ischaemia, divided into 34 and 25 cases of stoma necrosis and colonic necrosis, respectively. Compared with patients who did not require reoperation for mesenteric ischaemia following rectal cancer surgery, the proportion having high tie was greater (54.2% vs 38.5%; P = 0.032). The adjusted OR for reoperation due to any mesenteric ischaemia with high tie was 2.26 (95% CI 1.34-3.79), while the corresponding estimates for stoma and colonic necrosis, respectively, were 1.60 (95% CI 0.81-3.17) and 3.69 (95% CI 1.57-8.66). CONCLUSION: The incidence of reoperation for mesenteric ischaemia after abdominal resection for rectal cancer is low, but the use of a high tie might increase the risk of colonic necrosis demanding surgery.

Background: Anastomotic leakage following anterior resection for rectal cancer may result in death. The aim of this study was to yield an updated, population-based estimate of postoperative mortality and evaluate possible interacting factors. Methods: This was a retrospective national cohort study of patients who underwent anterior resection between 2007 and 2016. Data were retrieved from a prospectively developed database. Anastomotic leakage constituted exposure, whereas outcome was defined as death within 90 days of surgery. Logistic regression analyses, using directed acyclic graphs to evaluate possible confounders, were performed, including interaction analyses. Results: Of 6948 patients, 693 (10·0 per cent) experienced anastomotic leakage and 294 (4·2 per cent) underwent reintervention due to leakage. The mortality rate was 1·5 per cent in patients without leakage and 3·9 per cent in those with leakage. In multivariable analysis, leakage was associated with increased mortality only when a reintervention was performed (odds ratio (OR) 5·57, 95 per cent c.i. 3·29 to 9·44). Leaks not necessitating reintervention did not result in increased mortality (OR 0·70, 0·25 to 1·96). There was evidence of interaction between leakage and age on a multiplicative scale (P = 0·007), leading to a substantial mortality increase in elderly patients with leakage. Conclusion: Anastomotic leakage, in particular severe leakage, led to a significant increase in 90-day mortality, with a more pronounced risk of death in the elderly.

BACKGROUND AND AIMS: In mid-rectal cancer, the low colorectal anastomosis is, although feasible, sometimes avoided. The aim was to compare low Hartmann's procedure with intersphincteric abdomino-perineal excision of the rectum, in patients operated with total mesorectal excision for mid-rectal cancer in whom the low anastomosis was technically feasible but for patient-related reasons undesired. MATERIAL AND METHODS: A total of 64 consecutive patients with mid-rectal cancer who underwent low Hartmann's procedure (n = 34) or intersphincteric abdomino-perineal excision (n = 30) at one colorectal unit were compared regarding patient demography, short-term oncology, surgical outcome at 3 and 24 months, and long-term overall survival. RESULTS: There were no significant differences between intersphincteric abdomino-perineal excision and Hartmann's procedure regarding age, gender distribution, body mass index, preoperative radiotherapy, tumor level, or cancer stages. Operation time was shorter in Hartmann's procedure as compared with intersphincteric abdomino-perineal excision, median 174 and 256 min, (P < 0.001), and intraoperative blood loss was increased, 600 and 500 mL, respectively (P = 0.045). Number of lymph nodes and circumferential resection margin were comparable. In Hartmann's procedure compared with intersphincteric abdomino-perineal excision, the need for reoperation was 24% and 3%, (P = 0.020), complications classified as Clavien-Dindo 3-4 occurred in 32% and 10%, (P = 0.031), pelvic abscess in 21% and 10%, (P = 0.313), and mortality within 90 days was 3% and 0%, respectively, (P = 0.938). In intersphincteric abdomino-perineal excision, the perineal wound was not healed at 3 months in 13%, and in Hartmann's procedure 15% had chronic secretion from the anorectal remnant at 2 years postoperatively. CONCLUSION: The results from this study suggest that intersphincteric abdomino-perineal excision might be an alternative to Hartmann's procedure in patients with mid-rectal cancer, in whom a low colorectal anastomosis is undesired.

BACKGROUND: Emergency colorectal cancer surgery is associated with significant mortality. Induced adrenergic hyperactivity is thought to be an important contributor. Downregulating the effects of circulating catecholamines may reduce the risk of adverse outcomes. This study assessed whether regular preoperative beta-blockade reduced mortality after emergency colonic cancer surgery. METHODS: This cohort study used the prospectively collected Swedish Colorectal Cancer Registry to recruit all adult patients requiring emergency colonic cancer surgery between 2011 and 2016. Patients were subdivided into those receiving regular beta-blocker therapy before surgery and those who were not (control). Demographics and clinical outcomes were compared. Risk factors for 30-day mortality were evaluated using Poisson regression analysis. RESULTS: A total of 3187 patients were included, of whom 685 (21·5 per cent) used regular beta-blocker therapy before surgery. The overall 30-day mortality rate was significantly reduced in the beta-blocker group compared with controls: 3·1 (95 per cent c.i. 1·9 to 4·7) versus 8·6 (7·6 to 9·8) per cent respectively (P < 0·001). Beta-blocker therapy was the only modifiable protective factor identified in multivariable analysis of 30-day all-cause mortality (incidence rate ratio 0·31, 95 per cent c.i. 0·20 to 0·47; P < 0·001) and was associated with a significant reduction in death of cardiovascular, respiratory, sepsis and multiple organ failure origin. CONCLUSION: Preoperative beta-blocker therapy may be associated with a reduction in 30-day mortality following emergency colonic cancer surgery.

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) have been widely used in colorectal surgery due to their opioid-sparing effect. However, several studies have indicated an increased risk of anastomotic leakage following NSAID treatment, although conflicting results exist. The primary goal of this study was to further examine whether postoperative NSAIDs are independently associated with anastomotic leakage after anterior resection for rectal cancer. METHODS: Patients who underwent anterior resection for rectal cancer during 2007-2013 in 15 different hospitals in three healthcare regions in Sweden were included in the study. Registry data and information from patient records were retrieved. The association between NSAID treatment (for at least two days in the first postoperative week) and symptomatic anastomotic leakage (within 90 days) was evaluated with multiple logistic regression, with adjustment for pertinent confounding factors. RESULTS: Some 1495 patients were included in the study. Of these, 27% received postoperative NSAIDs for at least two days in the first postoperative week. Symptomatic anastomotic leakage occurred in 11% and 14% in the NSAID and non-NSAID group, respectively. With adjustment for confounders, the odds ratio for leakage among patients who received NSAIDs compared with those who did not was 0.88 (95% CI 0.65-1.20). No differences were seen between non-selective and COX-2-selective NSAIDs. CONCLUSION: Postoperative NSAID treatment does not seem to increase the risk of symptomatic anastomotic leakage after anterior resection for rectal cancer. NSAID use appears to be safe, but a well-powered randomized clinical trial is warranted.

AIM: Fashioning a defunctioning stoma is common when performing an anterior resection for rectal cancer in order to avoid and mitigate the consequences of an anastomotic leakage. We investigated the permanent stoma prevalence, factors influencing stoma outcome and complication rates following stoma reversal surgery. METHOD: Patients who had undergone an anterior resection for rectal cancer between 2007 and 2013 in the northern healthcare region were identified using the Swedish Colorectal Cancer Registry and were followed until the end of 2014 regarding stoma outcome. Data were retrieved by a review of medical records. Multiple logistic regression was used to evaluate predefined risk factors for stoma permanence. Risk factors for non-reversal of a defunctioning stoma were also analysed, using Cox proportional-hazards regression. RESULTS: A total of 316 patients who underwent anterior resection were included, of whom 274 (87%) were defunctioned primarily. At the end of the follow-up period 24% had a permanent stoma, and 9% of patients who underwent reversal of a stoma experienced major complications requiring a return to theatre, need for intensive care or mortality. Anastomotic leakage and tumour Stage IV were significant risk factors for stoma permanence. In this series, partial mesorectal excision correlated with a stoma-free outcome. Non-reversal was considerably more prevalent among patients with leakage and Stage IV; Stage III patients at first had a decreased reversal rate, which increased after the initial year of surgery. CONCLUSION: Stoma permanence is common after anterior resection, while anastomotic leakage and advanced tumour stage decrease the chances of a stoma-free outcome. Stoma reversal surgery entails a significant risk of major complications.

AIM: Previous research indicates that high tie of the inferior mesenteric artery during anterior resection for rectal cancer might be associated with an increased risk of postoperative functional disturbances. The goal of this population-based retrospective cohort study was to further investigate that association. METHOD: Patients who underwent anterior resection for rectal cancer from April 2011 to September 2012 were identified through the Swedish Colorectal Cancer Registry. Bowel and urogenital function were assessed by a postal questionnaire 2 years after surgery. Information on the level of mesenteric tie and clinical variables was retrieved from the registry. The outcome was defined as any defaecatory, urinary or sexual dysfunction as reported by the patient. The association between high tie and the outcome was evaluated with multivariable logistic and linear regression with adjustment for confounders, such as sex, body mass index, comorbidity and preoperative radiation. RESULTS: With a response rate of 86%, 805 patients were included in the study. Of these, 46% were operated with high tie. After adjustment for confounders, high tie did not affect the risk of faecal incontinence (OR 0.85; 95% CI 0.59-1.22), urinary incontinence (OR 0.94; 95% CI 0.63-1.41) or various aspects of sexual dysfunction (erectile dysfunction, anejaculation, dyspareunia and coital vaginal dryness). However, an association between high tie and defaecation at night was detected (OR 1.44; 95% CI 1.02-2.03). CONCLUSION: This study does not support that the level of vascular tie influences the risk of major defaecatory, urinary or sexual disturbances 2 years after anterior resection for rectal cancer.

AIM: Epidural analgesia reduces the surgical stress response. However, its effect on pro- and anti-inflammatory cytokines in the genesis of inflammation following major abdominal surgery remains unclear. Our main objective was to elucidate whether perioperative epidural analgesia prevents the inflammatory response following colorectal cancer surgery. METHODS: Ninety-six patients scheduled for open or laparoscopic surgery were randomized to epidural analgesia (group E) or patient-controlled intravenous analgesia (group P). Surgery and anaesthesia were standardized in both groups. Plasma cortisol, insulin and serum cytokines [interleukin 1ß (IL-1ß), IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-13, tumour necrosis factor α, interferon γ, granulocyte-macrophage colony-stimulating factor, prostaglandin E2 and vascular endothelial growth factor] were measured preoperatively (T0), 1-6 h postoperatively (T1) and 3-5 days postoperatively (T2). Mixed model analysis was used, after logarithmic transformation when appropriate, for analyses of cytokines and stress markers. RESULTS: >There were no significant differences in any serum cytokine concentration between groups P and E at any time point except for IL-10 which was 87% higher in group P [median and range 4.1 (2.3-9.2) pg/ml] compared to group E [2.6 (1.3-4.7) pg/ml] (P = 0.002) at T1. There was no difference in plasma cortisol and insulin between the groups at any time point after surgery. A significant difference in median serum cytokine concentration was found between open and laparoscopic surgery with higher levels of IL-6, IL-8 and IL-10 at T1 in patients undergoing open surgery compared to laparoscopic surgery. No difference in serum cytokine concentration was detected between the groups or between the surgical technique at T2. CONCLUSIONS: Open surgery, compared to laparoscopic surgery, has greater impact on these inflammatory mediators than epidural analgesia vs intravenous analgesia.

BACKGROUND: Defunctioning stoma in low anterior resection (LAR) for rectal cancer can prevent major complications, but overall cost-effectiveness for the healthcare provider is unknown. This study compared inpatient healthcare resources and costs within 5 years of LAR between two randomized groups of patients undergoing LAR with and without defunctioning stoma. METHOD: Five-year follow-up of a randomized, multicenter trial on LAR (NCT 00636948) with (stoma; n = 116) or without (no stoma; n = 118) defunctioning stoma comparing inpatient healthcare resources and costs. Unplanned stoma formation, days with stoma, length of hospital stay, reoperations, and total associated inpatient costs were analyzed. RESULTS: Average costs were 21.663 per patient with defunctioning stoma and 15.922 per patient without defunctioning stoma within 5 years of LAR, resulting in an average cost-saving of 5.741. There was no difference between groups regarding the total number of days with any stoma (stoma = 33 398 vs. no stoma = 34 068). The total number of unplanned reoperations were 70 (no stoma) and 32 (stoma); p < 0.001. In the group randomized to no stoma at LAR, 30.5% (36/118) required an unplanned stoma later. CONCLUSION: Randomization to defunctioning stoma in LAR was more expensive than no stoma, despite the cost-savings associated with a reduced frequency of anastomotic leakage. Both groups required the same total number of days with a stoma within five years of LAR.

AIM: The study compared the outcome of laparoscopic and open surgery in daily practice when performed in a strict Enhanced Recovery After Surgery (ERAS) environment. METHOD: Two-hundred and ninety-two consecutive patients who received elective surgery, in three Swedish ERAS centres, for cancer or adenoma in the right colon in the period 1 January 2011 to 31 December 2012, were prospectively registered in a Web-based ERAS database. Peri-operative data were collected from the database and patient charts. The primary end-points included postoperative recovery and morbidity. The secondary objective was to identify preoperative variables that influenced the selection of patients for laparoscopic or open surgery. RESULTS: One-hundred and twenty-three (42%) patients were selected for laparoscopic surgery. The overall preoperative ERAS-compliance rate was 87% and no significant difference was seen between the surgical techniques. In multivariate analysis, patients treated with laparoscopy had significantly earlier pain control (2.4 ± 3.2 days vs 4.2 ± 5.9 days; P = 0.016) and a shorter length of hospital stay (LOS) (4 days vs 6 days; P = 0.002) compared with open surgery. There was no significant difference in the complication rate [18.7% vs 21.3%; OR = 1.0 (95% CI: 0.5-2.0)], the number of lymph nodes removed or the rate of R0 resection between laparoscopic and open surgery. Tumours selected for laparoscopy were generally smaller, had a lower T-stage and were predominantly situated in the caecum and the ascending colon compared with those of patients selected for open surgery. CONCLUSION: The use of laparoscopy in routine right-sided colectomy in an ERAS environment, with data on outcome corrected for selection bias, may result in faster recovery compared with open surgery.
