RESUMO
BACKGROUND: The development of new perioperative treatment modalities to activate the immune system in colorectal cancer might have a beneficial effect on reducing the risk of recurrence after surgery. Calcium electroporation is a promising treatment modality that potentially modulates the tumor microenvironment. The aim of this study was to evaluate the safety of the procedure in the neoadjuvant setting in localized left-sided colorectal cancer (CRC). METHODS: The study included patients with potentially curable sigmoid or rectal cancer with no indication for other neoadjuvant treatment. Patients were offered calcium electroporation as a neoadjuvant treatment before elective surgery. Follow-up visits were conducted on the preoperative day before elective surgery, POD2, POD14, and POD30, with an evaluation of adverse events, impact on elective surgery, clinical examination, and quality of recovery. RESULTS: Endoscopic calcium electroporation was performed as an outpatient procedure in all 21 cases, with no procedure-related complications reported. At follow-up, five adverse events were registered, two of which were classified as serious adverse events. Surgery was performed as planned in 19 patients (median time to surgery, 8 days), and the final two patients underwent surgery with a delay due to adverse events (14 and 33 days). No significant impact on the quality of recovery scores nor inflammatory markers were seen before and after calcium electroporation, nor baseline and POD30. CONCLUSIONS: Endoscopic calcium electroporation is a safe and feasible procedure in patients with potentially curable CRC. The study showed limited side effects and limited impact on the following elective surgical resection.

BACKGROUND: The implementation of Enhanced Recovery After Surgery (ERAS) protocols has resulted in improved postoperative outcomes in colorectal cancer surgery. The evidence regarding feasibility and impact on outcomes in surgery for inflammatory bowel disease (IBD) is limited. METHODS: We performed a retrospective observational cohort study, comparing patient trajectories before and after implementing an IBD-specific ERAS protocol at Zealand University Hospital. We assessed the occurrence of serious postoperative complications of Clavien-Dindo grade 3 or higher as our primary outcome, with postoperative length of stay in days and rate of readmissions as secondary outcomes, using χ2, Mann-Whitney test, and odds ratios adjusted for sex and age. RESULTS: From 2017 to 2023, 394 patients were operated on for IBD and included in our study. In the ERAS cohort, 39/250 patients experienced a postoperative complication of Clavien-Dindo grade 3 or higher compared to 27/144 patients in the non-ERAS cohort (15.6% vs. 18.8%, p = 0.420) with an adjusted odds ratio of 0.73 (95% CI 0.42-1.28). There was a significantly shorter postoperative length of stay (median 4 vs. 6 days, p < 0.001) in the ERAS cohort compared to the non-ERAS cohort. Readmission rates remained similar (22.4% vs. 16.0%, p = 0.125). CONCLUSIONS: ERAS in IBD surgery was associated with faster patient recovery, but without an impact on the occurrence of serious postoperative complications and rate of readmissions.

BACKGROUND: Incontinence is not rare after rectal cancer surgery. Platelet-rich plasma may promote tissue repair and generation but has never been tested for the treatment of anal incontinence. This study evaluated the impact of platelet-rich plasma injection on the severity of incontinence and quality of life after low rectal cancer surgery. METHODS: This is a prospective cohort proof of concept study in a colorectal cancer institution. Patients had undergone low anterior or intersphincteric resection for low rectal cancer and had a Wexner score > 4. Ten milliliters of platelet-rich plasma were injected into the internal and external sphincters under endoanal ultrasound (EAUS) guidance. Primary outcome measure was > 2 point improvement in Wexner score (improved group). The patients were assessed with endo-anal ultrasound examination, manometry, the Wexner Questionnaire and SF-36 Health Surveys, and patients were asked whether they used pads and antidiarrheal medications before and 6 months after PRP injection. RESULTS: Of 20 patients included in the study, 14 (70%) were men, and the average age was 56.8 (SD = 9.5) years. No statistically significant difference was found in Wexner scores before and after PRP injection (p = 0.66). Seven (35%) patients experienced a > 2 point improvement in Wexner score. Rectal manometry demonstrated improved squeezing pressure (p = 0.0096). Furthermore, physical functioning scoring (p = 0.023), role limitation (p = 0.016), emotional well-being (p = 0.0057) and social functioning (p = 0.043) domains on the SF-36 questionnaire improved. One (5%) and three (15%) patients stopped using pads and antidiarrheal medications. CONCLUSION: Platelet-rich plasma injection does not restore Wexner scores, but more than one-third of patients may benefit from this application with an improvement of > 2 points in their scores. Platelet-rich plasma injection may improve squeezing pressure and certain life quality measures for incontinent patients after rectal cancer surgery.

BACKGROUND: The standard operation for mid- and low rectal cancer total mesorectal excision (TME) is routinely performed as minimally invasive surgery. TME is associated with temporary or permanent functional impairment of pelvic organs, causing reduced quality of life (QoL). Concerns have been raised that the newest minimally invasive approach, transanal TME (TaTME), may further reduce urogenital and anorectal functions. OBJECTIVE: To determine if functional outcomes affecting QoL are altered after TaTME. Primary end-point is the impact of TaTME on QoL and functional outcomes. Secondary end-point is assessing differences in QoL and functional outcomes after TME surgery from below (TaTME) or above (transabdominal TME). DESIGN, SETTING, AND PARTICIPANTS: Observational study consisting of prospectively registered self-reported questionnaire data collected at baseline and follow-ups after TaTME. All patients who underwent TaTME during the Danish national implementation phase were included. Central surveillance of the implementation included questionnaires concerning QoL and functional outcomes. Analyses of functional results from the Danish cohort of the ROLARR trial (Jayne et al. in JAMA 318:1569-1580, (2017) are reported separately for perspective, representing the transabdominal approach to TME, i.e., laparoscopic- or robotic-assisted TME (LaTME/RoTME). Applied questionnaires include EORTC QLQ-C30, SF-36, LARS, ICIQ-MLUTS, ICIQ-FLUTS, IPSS, IIEF, SVQ, and FSFI. RESULTS: A total of 115 TaTME procedures were registered August 2016 to April 2019. LaTME/RoTME patients (n = 92) were operated on January 2011 to September 2014. A temporary postoperative decrease of QoL (global health status and functional scales) was observed, yet long-term results were unaffected by surgery in both groups. In TaTME patients, the anorectal dysfunction increased significantly (p < 0.001) from preoperative baseline to 13.5 months follow-up, where 67.5% (n = 52) reported major LARS symptoms. Urinary function was not significantly impaired after TME regardless of technique. The paucity of responses concerning sexual function precludes conclusions. CONCLUSIONS: Although an initial reduction in QoL after TME occurs, it normalizes within the first year postoperatively. In concurrence with international results, we found that significant anorectal dysfunction is common after TaTME. No data on anorectal function was available for LaTME/RoTME patients for comparison. We found no indications that transanal TME is inferior to transabdominal TME surgery concerning urogenital functions or health-related QoL.

BACKGROUND: The occurrence of postoperative complications and anastomotic leakage are major drivers of mortality in the immediate phase after colorectal cancer surgery. We trained prediction models for calculating patients' individual risk of complications based only on preoperatively available data in a multidisciplinary team setting. Knowing prior to surgery the probability of developing a complication could aid in improving informed decision-making by surgeon and patient and individualize surgical treatment trajectories. METHODS: All patients over 18 years of age undergoing any resection for colorectal cancer between January 1, 2014 and December 31, 2019 from the nationwide Danish Colorectal Cancer Group database were included. Data from the database were converted into Observational Medical Outcomes Partnership Common Data Model maintained by the Observation Health Data Science and Informatics initiative. Multiple machine learning models were trained to predict postoperative complications of Clavien-Dindo grade ≥ 3B and anastomotic leakage within 30 days after surgery. RESULTS: Between 2014 and 2019, 23,907 patients underwent resection for colorectal cancer in Denmark. A Clavien-Dindo complication grade ≥ 3B occurred in 2,958 patients (12.4%). Of 17,190 patients that received an anastomosis, 929 experienced anastomotic leakage (5.4%). Among the compared machine learning models, Lasso Logistic Regression performed best. The predictive model for complications had an area under the receiver operating characteristic curve (AUROC) of 0.704 (95%CI 0.683-0.724) and an AUROC of 0.690 (95%CI 0.655-0.724) for anastomotic leakage. CONCLUSIONS: The prediction of postoperative complications based only on preoperative variables using a national quality assurance colorectal cancer database shows promise for calculating patient's individual risk. Future work will focus on assessing the value of adding laboratory parameters and drug exposure as candidate predictors. Furthermore, we plan to assess the external validity of our proposed model.

Remote ischaemic preconditioning reduces the risk of myocardial injury within 4 days of hip fracture surgery. We aimed to investigate the effect of remote ischaemic preconditioning on the incidence of major adverse cardiovascular events 1 year after hip fracture surgery. We performed a phase-2, multicentre, randomised, observer-blinded, clinical trial between February 2015 and September 2017. We studied patients aged ≥ 45 years with a hip fracture and a minimum of one cardiovascular risk factor. Patients were allocated randomly to remote ischaemic preconditioning applied just before surgery or no treatment (control group). Remote ischaemic preconditioning was performed on the upper arm with a tourniquet in four cycles of 5 min ischaemia and 5 min reperfusion. Primary outcome was the occurrence of major adverse cardiovascular events within 1 year of surgery. A total of 316 patients were allocated randomly to the remote ischaemic preconditioning group and 309 patients to the control group. Major adverse cardiovascular events occurred in 43 patients (13.6%) in the remote ischaemic preconditioning group compared with 51 patients (16.5%) in the control group (adjusted hazard ratio (95%CI) 0.83 (0.55-1.25); p = 0.37). Fewer patients in the remote ischaemic preconditioning group had a myocardial infarction (11 (3.5%) vs. 22 (7.1%); hazard ratio (95%CI) 0.48 (CI 0.23-1.00); p = 0.04). Remote ischaemic preconditioning did not reduce the occurrence of major adverse cardiovascular events within 1 year of hip fracture surgery. The effect of remote ischaemic preconditioning on clinical cardiovascular outcomes in non-cardiac surgery needs confirmation in appropriately powered randomised clinical trials.

BACKGROUND: Systemic inflammation following curative surgery for colorectal cancer may be associated with increased risk of recurrence. [Correction added on 29 November 2019, after first online publication: text amended for accuracy.] This study investigated whether a clinically suspected infection, for which blood cultures were sent within 30 days after surgery for colorectal cancer, was associated with long-term oncological outcomes. METHODS: This register-based national cohort study included all Danish residents undergoing surgery with curative intent for colorectal cancer between January 2003 and December 2013. Patients who developed recurrence or died within 180 days after surgery were not included. Associations between blood cultures taken within 30 days after primary surgery and overall survival, disease-free survival and recurrence-free survival were analysed using Cox regression models adjusted for relevant clinical confounders, including demographic data, cancer stage, co-morbidity, blood transfusion, postoperative complications and adjuvant chemotherapy. RESULTS: The study included 21 349 patients, of whom 3390 (15·9 per cent) had blood cultures taken within 30 days after surgery. Median follow-up was 5·6 years. Patients who had blood cultures taken had an increased risk of all-cause mortality (hazard ratio (HR) 1·27, 95 per cent c.i. 1·20 to 1·35; P < 0·001), poorer disease-free survival (HR 1·22, 1·16 to 1·29; P < 0·001) and higher risk of recurrence (HR 1·15, 1·07 to 1·23; P < 0·001) than patients who did not have blood cultures taken. CONCLUSION: A clinically suspected infection requiring blood cultures within 30 days of surgery for colorectal cancer was associated with poorer oncological outcomes.
ANTECEDENTES: La inflamación sistémica en el cáncer colorrectal puede asociarse con un aumento del riesgo de recidiva. En este estudio se investigó si la sospecha clínica de infección, en la que se obtuvieron cultivos de sangre periférica durante los primeros 30 días de la cirugía por cáncer colorrectal, se asociaba con los resultados oncológicos a largo plazo. MÉTODOS: Se trata de un estudio de cohortes de un registro de una base de datos nacional, que incluyía todos los sujetos residentes en Dinamarca sometidos a cirugía por cáncer colorrectal con intención curativa desde enero de 2003 a diciembre de 2013. Los pacientes con recidiva o que fallecieron durante los primeros 180 días después de la cirugía fueron excluidos. Se estimaron las asociaciones entre los cultivos de sangre periférica efectuados en los primeros 30 días tras la cirugía primaria y la supervivencia global, supervivencia libre de enfermedad y supervivencia libre de recidiva mediante modelos de regresión de Cox, ajustados por variables clínicas confusoras relevantes (incluyendo datos demográficos, estadio del cáncer, comorbilidad, transfusión de sangre, complicaciones postoperatorias y quimioterapia adyuvante). RESULTADOS: El estudio incluyó 21.349 pacientes, de los cuales en 3.390 (16%) se habían obtenido cultivos de sangre periférica durante los primeros 30 días tras la cirugía. La mediana de seguimiento fue de 5,6 años. Los pacientes en los que se había obtenido cultivos de sangre periférica presentaron un riesgo aumentado de mortalidad por cualquier causa (cociente de riesgos instantáneos, hazard ratio, HR 1,27, i.c. del 95% 1,20-1,35; P < 0.0001), peor supervivencia libre de enfermedad (HR 1,22, i.c. del 95% 1,16-1,29; P < 0,0001) y mayor riesgo de recidiva (HR 1,15, i.c. del 95% 1,07-1,23; P < 0,0001) que los pacientes en los que no se habían obtenido cultivos. CONCLUSIÓN: La presencia de una infección sospechada clínicamente para la cual se requiere obtener cultivos de sangre periférica en los primeros 30 días tras cirugía por cancer colorrectal se asoció con peores resultados oncológicos.

AIM: The aim of this study was to validate the clinical quality database of the Danish Colorectal Cancer Group. The validation is meant to focus on core data regarding staging of the disease, treatment provided, patient-related factors and key complications. METHOD: This was a database validation study assessing the completeness of the database and the accuracy of the data by re-entering core variables into an online module in a blinded fashion and comparing re-entered data with the original database data. A sample of 5% of patients from the years 2014-2017 was randomly selected. RESULTS: The sample of 936 patients was identified and data were re-entered. The completeness of the data retrieved was a median of 96%, 100% and 99% for preoperative, intra-operative and postoperative variables, respectively. The overall accuracy was a median of 95%. The least accurate variable was date of diagnosis (50% perfect agreement), with agreement rising to 96% when near matches defined as correct date ± 30 days were included. Intra-operative variables were of high quality, as were data on surgical complications including anastomotic leakage, where agreement was 97%. CONCLUSION: This was the first major validation of the Danish Colorectal Cancer Group's database. Overall, the completeness and quality of data were high, but the validation process also identified weaknesses, which can be crucial for future users to acknowledge and consider.

AIM: The aim of this work was to examine (1) the incidence of primary repair, (2) the incidence of recurrent repair and (3) the types of repair performed in patients with parastomal bulging. METHOD: Prospectively collected data on parastomal bulging from the Danish Stoma Database were linked to surgical data on repair of parastomal bulging from the Danish National Patient Register. Survival statistics provided cumulative incidences and time until primary and recurrent repair. RESULTS: In the study sample of 1016 patients with a permanent stoma and a parastomal bulge, 180 (18%) underwent surgical repair. The cumulative incidence of a primary repair was 9% [95% CI (8%; 11%)] within 1 year and 19% [95% CI (17%; 22%)] within 5 years after the occurrence of a parastomal bulge. We found a similar probability of undergoing primary repair in patients with ileostomy and colostomy. For recurrent repair, the 5-year cumulative incidence was 5% [95% CI (3%; 7%)]. In patients undergoing repair, the probability was 33% [95% CI (21%; 46%)] of having a recurrence requiring repair within 5 years. The main primary repair was open or laparoscopic repair with mesh (43%) followed by stoma revision (39%). Stoma revision and repair with mesh could precede or follow one another as primary and recurrent repair. Stoma reversal was performed in 17% of patients. CONCLUSION: Five years after the occurrence of a parastomal bulge the estimated probability of undergoing a repair was 19%. Having undergone a primary repair, the probability of recurrent repair was high. Stoma reversal was more common than expected.

AIM: Enhanced recovery after surgery programmes in elective colorectal surgery have been developed and implemented widely, but a subgroup of patients may still require longer hospital stays than expected. The aim of this study was to identify and describe factors compromising early postoperative recovery by asking 'why is the patient still in hospital today?' after laparoscopic colorectal cancer surgery within an enhanced recovery after surgery programme. METHOD: Patients undergoing elective laparoscopic colorectal cancer resection were evaluated postoperatively with predefined potential reasons for still being in hospital. The primary outcome was 'reason for still being in hospital' on postoperative day 0-4 and secondarily length of stay with a focus on differences between patients with and without a stoma. RESULTS: Ninety-six patients having colorectal cancer surgery were included. The median length of stay for the whole group was 3 days (range 1-14). The four dominant causes for patients without a stoma to be in hospital were lack of gastrointestinal function, lack of early mobilization, lack of normal micturition and nausea. Patients with a stoma stayed in hospital due to stoma training, lack of gastrointestinal function, lack of free micturition and a miscellaneous 'others' group. CONCLUSION: Delayed gastrointestinal function, insufficient mobilization, poor urinary function and stoma care training have been characterized as dominant compromising factors for postoperative recovery. Together with a focus on frailty, future studies should focus on improving early mobilization, prevention and treatment of postoperative urinary retention and improved stoma care training, in order to minimize delay in postoperative recovery and discharge.

AIM: Total mesorectal excision (TME) is the standard of care for rectal cancer, which can be combined with low anterior resection (LAR) in patients with mid-to-low rectal cancer. The narrow pelvic space and difficulties in obtaining adequate exposure make surgery technically challenging. Four techniques are used to perform the surgery: open laparotomy, laparoscopy, robot-assisted surgery and transanal surgery. Comparative data for these techniques are required to provide clinical data on the surgical management of rectal cancers. METHODS: The Rectal Surgery Evaluation Trial will be a prospective, observational, case-matched, four-cohort, multicentre trial designed to study TME with LAR using open laparotomy, laparoscopy, robot-assisted surgery or transanal surgery in high-surgical-risk patients with mid-to-low non-metastatic rectal cancer. All surgeries will be performed by surgeons experienced in at least one of the techniques. Oncological, morbidity and functional outcomes will be assessed in a composite primary outcome, with success defined as circumferential resection margin ≥ 1 mm, TME Grade III and minimal postoperative morbidity (absence of Clavien-Dindo Grade III-IV complications within 30 days after surgery). Secondary end-points will include the co-primary end-points over the long term (2 years), quality of surgery, quality of life, length of hospital stay, operative time and rate of unplanned conversions. DISCUSSION: This will be the first trial to study all four surgical techniques currently used for TME with LAR in a specific group of high-risk patients. The knowledge obtained will contribute towards helping physicians determine the advantages of each technique and which may be the most appropriate for their patients.

AIM: Robotic techniques are being increasingly used in colorectal surgery. There is, however, a lack of training opportunities and structured training programmes. Robotic surgery has specific problems and challenges for trainers and trainees. Ergonomics, specific skills and user-machine interfaces are different from those in traditional laparoscopic surgery. The aim of this study was to establish expert consensus on the requirements for a robotic train-the-trainer curriculum amongst robotic surgeons and trainers. METHOD: This is a modified Delphi-type study involving 14 experts in robotic surgery teaching. A reiterating 19-item questionnaire was sent out to the same group and agreement levels analysed. A consensus of 0.8 or higher was considered to be high-level agreement. RESULTS: Response rates were 93-100% and most items reached high levels of agreement within three rounds. Specific requirements for a robotic faculty development curriculum included maximizing dual-console teaching, theatre team training, nontechnical skills training, patient safety, user-machine interface training and telementoring. CONCLUSION: A clear need for the development of a train-the-trainer curriculum has been identified. Further research is needed to assess feasibility, effectiveness and clinical impact of a robotic train-the-trainer curriculum.

Episodic and ongoing hypoxaemia are well-described after surgery, but, to date, no studies have investigated the occurrence of episodic hypoxaemia following minimally-invasive colorectal surgery performed in an enhanced recovery setting. We aimed to describe the occurrence of postoperative hypoxaemia after minimally-invasive surgery in an enhanced recovery setting, and the association with morphine use, incision site, fluid intake and troponin increase. We performed a prospective observational study of 85 patients undergoing minimally-invasive surgery for colorectal cancer between 25 August 2016 and 17 August 2017. We applied a pulse oximeter with a measurement rate of 1 Hz immediately after surgery either until discharge or until two days after surgery, and recorded the oxygen saturation. We measured troponin I during the first four days after surgery, or until discharge. The median (IQR [range]) length of stay was 3 (2-4 [1-38]) days. Thirty-six percent of patients spent more than 1 h below an oxygen saturation of 90% (4.2% of the day), and with a median (IQR [range]) proportion of 1.3 (0.2-11.1 [0.0-21.4])% of the day spent with an oxygen saturation below 88%. We found no associations between time spent below an oxygen saturation of 88% and morphine use (p = 0.215), fluid intake (p = 0.446), complications (p = 0.808) or extraction site (p = 0.623). Postoperative increases in troponin I were associated both with time spent below an oxygen saturation of 88% (p = 0.026) and hypopnoea episodes (p = 0.003). Even with minimally-invasive surgery and enhanced recovery after surgery, episodic hypoxaemia and hypopnoea episodes are common, but are not associated with morphine use, fluid intake or incision site. Further studies should investigate the relationship between hypoxaemia and troponin increase.

PURPOSE: Accurate staging of colonic cancer is important for patient stratification. We aimed to correlate the diagnostic accuracy of preoperative computed tomography (CT) with final histopathology as reference standard. METHODS: Data was collected retrospectively on 615 consecutive patients operated for colonic cancer. Evaluation was based upon T-stage. Patients were stratified into high-risk and low-risk groups, based on the extent of tumor invasion beyond the proper muscle layer of more or less than 5 mm. The Kendall tau correlation coefficient was used to calculate concordance between radiological (r)T-stage obtained at CT imaging and pathological (p)T-stage from the final pathology. RESULTS: In total, 501 patients were included. We found no significant differences in the Kendall tau values for diagnostic measures between the groups at the 95% confidence interval (CI) level: 49% (95% CI, 43-55) for all individuals, 48% (95% CI, 40-56) for screened individuals, and 47% (95% CI, 37-56) for non-screened individuals. The overall sensitivity and specificity for all individuals in identifying high-risk tumors on CT was 65% (95% CI, 56-73) and 89% (95% CI, 85-92). The risk of ending up in the high-risk group due to overstaging among all individuals was calculated as the number needed to harm 11.7 (95% CI, 9-16). CONCLUSIONS: There is basis for improvement of CT-based preoperative staging of patients with colorectal cancer. Supplementary modalities may be needed for correct staging of patients preoperatively, especially in relation to stratification of patients into neoadjuvant treatments or tailored therapy in patients with early cancers.

BACKGROUND: The QoR-15 is a patient-reported outcome questionnaire that measures the quality of recovery after surgery and anaesthesia. We aimed to perform a systematic review and meta-analysis of the measurement properties of the QoR-15. METHODS: Studies reporting measurement properties or interpretability of the QoR-15 after surgery were eligible for inclusion. All languages were included in the PubMed and Embase search. The COSMIN guidelines for systematic reviews of patient-reported outcome measurements were followed. Criteria for good measurement properties outlined in the consensus-based guidelines for selecting outcome measurement instruments for clinical trials were applied. A metaanalysis and synthesis of data across studies was performed. RESULTS: Nine hundred and thirty-three titles were identified, and six articles were included in the study. The study population comprised 1548 patients undergoing a variety of surgical elective procedures. The QoR-15 was validated in English, Danish, Chinese, and Portuguese. High-quality evidence for good content validity, good internal consistency (Cronbach's α of 0.836), and essential unidimensionality of the QoR-15 as a measurement of postoperative quality of recovery was found. There was at least moderate-quality evidence of good reliability of the QoR-15 (intraclass correlation of 0.989) and good error of measurement (standard error of measurement of 1.85). The upper 95% confidence limit of the smallest detectable change was 3.63, and the minimal clinical important difference was 8.0. CONCLUSIONS: The QoR-15 fulfils requirements for outcome measurement instruments in clinical trials and is the first measurement instrument of postoperative quality of recovery to undergo a systematic review according to the COSMIN checklist.

AIM: The present database study aimed to identify patients with a longer postoperative length of stay (LOS) or patients readmitted and to characterize both groups based on perioperative factors. METHOD: A retrospective review of the Danish Colorectal Cancer Group database and a local database was performed of all patients undergoing elective resection for colorectal cancer in a 25-month period. The primary outcome was the number of patients with a prolonged hospital stay (LOS ≥ 10 days after the primary operation) and readmissions within 30 days after discharge. RESULTS: A total of 372 patients with colon resection and 215 patients with rectal resection were included. Patients undergoing colonic resection had a rate of prolonged hospital stay of 10.6% and a readmission rate of 13.7%; prolonged hospital stay was significantly associated with age ≥ 76 years and those who underwent a conversion from a laparoscopic procedure. Patients undergoing rectal cancer resection had a rate of prolonged hospital stay of 17.7% and a readmission rate of 14.0%; Charlson comorbidity score (CCS) ≥ 2, total mesorectal excision (TME) and laparoscopic conversion were significantly associated with prolonged hospital stay, and American Society of Anesthesiologists (ASA) score ≥ 3, TME and a duration of surgery ≥ 300 min were significantly associated with readmission. CONCLUSION: In patients with colon cancer, older age and conversion to open surgery were associated with prolonged hospital stay. In patients with rectal cancer, CCS ≥ 2, TME and conversion were associated with prolonged hospital stay, and a preoperative ASA score ≥ 3, TME and a duration of surgery ≥ 300 min were associated with readmission.

AIM: The aim was to investigate the incidence and risk factors for parastomal bulging, a clinically important complication, in patients with an ileostomy or colostomy. METHOD: The Danish Stoma Database Capital Region prospectively collects data on patients with a stoma up to a year after surgery. Stoma care nurses clinically assessed the main outcome, parastomal bulging. We linked data from the Stoma Database to data from the Danish Anaesthesia Database. Cumulative incidence of parastomal bulging over the first year was calculated with death and stoma reversal as competing risks. Risk factors were investigated using an exploratory approach. RESULTS: In a study population of 5019, the cumulative incidence (with competing risks) of parastomal bulging was 36.2% at 400 days after surgery. Age, colostomy, male gender, alcohol consumption and laparoscopy were associated with an increased risk of parastomal bulging. Compared with cancer, inflammatory bowel disease was associated with a lower risk of parastomal bulging, and diverticulitis was associated with a higher risk. Peristomal mesh and stomas placed through a separate incision were associated with a reduction in risk. There was neither increased nor decreased risk of parastomal bulging for body mass index, American Society of Anesthesiologists score, smoking status, emergency surgery and preoperative stoma site marking. CONCLUSION: Parastomal bulging is a common complication affecting one in three patients within 1 year of surgery. Along with previous findings, there is now considerable evidence for age and colostomy as being risk factors for parastomal bulging.

BACKGROUND: Delirium is a serious condition often experienced by critically ill patients in intensive care units (ICUs). The role of circadian light for this condition is unclear. The aim of this study was to describe incidence of delirium, risk factors for delirium, and the association between delirium and circadian light for patients in the ICU. METHODS: This is a retrospective cohort study of all patients at a Danish ICU from 1 August 2015 to 31 January 2016. Exclusion criteria were heavy sedation, no Confusion Assessment Method for the ICU (CAM-ICU) scores, or inability to communicate in Danish. Delirium was defined as at least one positive CAM-ICU score or treatment with haloperidol. Three of nine beds at the ICU had a circadian light installation. Allocation to ICU beds with or without circadian light depended on availability at admission. Risk factors for development of delirium were analyzed by simple and multiple logistic regression. RESULTS: We included 183 patients in the study. The incidence of delirium was 28% (95% CI 22, 35). Allocation to beds with or without circadian lighting was not associated with delirium incidence (OR 1.14; 95% CI 0.55, 2.37; P = 0.73). We found that Simplified Acute Physiology Score II (SAPS II) (OR 1.03; 95% CI 1.01, 1.06; P = 0.002), and dexmedetomidine was associated with delirium (OR 4.14; 95% CI 1.72, 10.03; P = 0.002). CONCLUSION: In this population of patients admitted to an ICU during 6 months, the incidence of delirium was 28%. We did not find an association between circadian light and development of delirium.

BACKGROUND: Few studies have investigated the effects of preoperative dexamethasone in acute surgical patients. This study examined the effects of 8 mg dexamethasone administered intravenously 30 min before surgery for suspected acute appendicitis. METHODS: A multicentre, parallel-group, double-blind, placebo-controlled study was conducted at two university hospitals in Denmark. Adults undergoing laparoscopic surgery for suspected appendicitis were eligible for inclusion. Participants, healthcare staff and investigators were blinded until all data analysis had been done. The primary outcome was the incidence of postoperative nausea and vomiting (PONV) during the first postoperative day. Secondary outcomes were pain, fatigue, sleep, opioid consumption, use of antiemetics, quality of recovery and duration of convalescence. Analysis was done according to the intention-to-treat principle. RESULTS: A total of 120 patients were enrolled; 57 patients in the dexamethasone group and 59 in the placebo group were eligible for primary analysis. In the dexamethasone group, 47 (95 per cent c.i. 35 to 60) per cent of patients experienced PONV compared with 63 (50 to 74) per cent) in the placebo group. The absolute risk reduction in PONV was 15 (-3 to 33) per cent in favour of the dexamethasone group (P = 0·098). Patients in the dexamethasone group had less pain at rest (difference in score on visual analogue scale (VAS) 9 (95 per cent c.i. 1 to 17) mm; P = 0·024), were less fatigued (difference in VAS score 7 (0 to 14) mm; P = 0·038), used fewer opioids (absolute risk reduction 17 (2 to 33) per cent; P = 0·033) and had better quality of recovery (difference in QoR-15 score 13 (4 to 22); P = 0·006) during the first postoperative day. There was no difference in postoperative complications (P = 0·595). CONCLUSION: Preoperative dexamethasone did not reduce PONV by the target level of 50 per cent.
