RESUMO
Disentangling the evolution of the molecular processes and genetic networks that facilitate the emergence of morphological novelties is one of the main objectives in evolutionary developmental biology. Here, we investigated the evolutionary history of a gene regulatory network controlling the development of novel tooth-like feeding structures in diplogastrid nematodes. Focusing on NHR-1 and NHR-40, the two transcription factors that regulate the morphogenesis of these feeding structures in Pristionchus pacificus, we sought to determine whether they have a similar function in Caenorhabditis elegans, an outgroup species to the Diplogastridae which has typical "rhabditid" flaps instead of teeth. Contrary to our initial expectations, we found that they do not have a similar function. While both receptors are co-expressed in the tissues that produce the feeding structures in the two nematodes, genetic inactivation of either receptor had no impact on feeding-structure morphogenesis in C. elegans. Transcriptomic experiments revealed that NHR-1 and NHR-40 have highly species-specific regulatory targets. These results suggest two possible evolutionary scenarios: either the genetic module responsible for feeding-structure morphogenesis in Diplogastridae already existed in the last common ancestor of C. elegans and P. pacificus, and subsequently disintegrated in the former as NHR-1 and NHR-40 acquired new targets, or it evolved in conjunction with teeth in Diplogastridae. These findings indicate that feeding-structure morphogenesis is regulated by different genetic programs in P. pacificus and C. elegans, hinting at developmental systems drift during the flap-to-tooth transformation. Further research in other "rhabditid" species is needed to fully reconstruct the developmental genetic changes which facilitated the evolution of novel feeding structures in Diplogastridae.

BACKGROUND & AIMS: Inflammatory bowel disease (IBD) is frequently accompanied by kidney complications. Potential triggers or subpopulations at high-risk of kidney problems are not well-elucidated. We hypothesized that surgical interventions, specifically colectomy, might in part explain this risk. METHODS: This study was a nationwide Swedish cohort study comprising 82,051 individuals with biopsy-proven IBD diagnosed during 1965 to 2017, with follow-up until 2019. We investigated the association between incident colectomy (time-varying exposure) and future risk of acute kidney injury (AKI) and kidney failure (diagnosis of end-stage kidney disease or death due to chronic kidney disease) using Cox proportional hazard models. We also examined the impact of partial vs total colectomy and the presence/duration of a stoma. Covariates included demographics, education level, and selected comorbidities. RESULTS: Over a median follow-up of 14 years, 16,479 individuals underwent colectomy, and 2556 AKI and 1146 kidney failure events occurred. Colectomy was associated with an increased relative risk of both AKI (adjusted hazard ratio, 2.37; 95% confidence interval, 2.17-2.58) and kidney failure (adjusted hazard ratio, 1.54; 95% confidence interval, 1.34-1.76). Compared with pre-colectomy periods, undergoing total colectomy and colectomy with prolonged stoma showed higher risks of both kidney outcomes versus partial colectomy or colectomy with a temporary stoma, respectively. Subgroup analyses suggested higher risks in patients with ulcerative colitis. CONCLUSIONS: In people with IBD, rates of AKI and kidney failure are higher among those undergoing colectomy, particularly among those following total colectomy, or colectomy with a prolonged stoma. This study identifies a high-risk population that may benefit from established protocols for kidney function monitoring/surveillance and referral to nephrologist care.
RESUMO
BACKGROUND: In this study, we aimed to identify the risk factors in patients with rectal anastomotic re-leakage and develop a prediction model to predict the probability of rectal anastomotic re-leakage after stoma closure. METHODS: This study was a single-center retrospective analysis of patients with rectal cancer who underwent surgery between January 2010 and December 2020. Among 3225 patients who underwent Total or Partial Mesorectal Excision (TME/PME) surgery for rectal cancer, 129 who experienced anastomotic leakage following stoma closure were enrolled. Risk factors for rectal anastomotic re-leakage were analyzed, and a prediction model was established for rectal anastomotic re-leakage. RESULTS: Anastomotic re-leakage after stoma closure developed in 13.2% (17/129) of patients. Multivariable analysis revealed that neoadjuvant chemoradiotherapy (odds ratio, 4.07; 95% confidence interval, 1.17-14.21; p = 0.03), blood loss > 50 ml (odds ratio, 4.52; 95% confidence interval, 1.31-15.63; p = 0.02), and intersphincteric resection (intersphincteric resection vs. low anterior resection: odds ratio, 6.85; 95% confidence interval, 2.01-23.36; p = 0.002) were independent risk factors for anastomotic re-leakage. A nomogram was constructed to predict the probability of anastomotic re-leakage, with an area under the receiver operating characteristic curve of 0.828 in the cohort. Predictive results correlated with the actual results according to the calibration curve. CONCLUSIONS: Neoadjuvant chemoradiotherapy, blood loss > 50 ml, and intersphincteric resection are independent risk factors for anastomotic re-leakage following stoma closure. The nomogram can help surgeons identify patients at a higher risk of rectal anastomotic re-leakage.

BACKGROUND: Nutrition plays a vital role in shaping the intestinal microbiome. However, many hospitalized children undergo periods of fasting during medical treatment. Changes to the small intestinal microbiota in early life in the setting of enteral deprivation have not been well described. OBJECTIVE: The aim of this study was to investigate the impact of enteral deprivation on the small intestinal mucosal microbiome and to identify factors that shape this interaction in infancy. METHODS: Intestinal biopsies were collected from proximal (fed) and distal (unfed) small bowel at the time of ostomy closure in children with a small intestinal enterostomy. Mucosal and luminal microbiome comparisons were performed including ß-diversity and differential abundance and correlations with clinical factors were analyzed. Host proteomics were compared between fed and unfed samples and correlated with microbiome parameters. Finally, microbial results were validated in another cohort of pediatric patients. RESULTS: Samples from 13 children (median age 84 d) were collected. Mucosal microbiome communities in the fed and unfed segments were strikingly similar [paired UniFrac distance (ß-diversity)], whereas luminal effluent differed significantly from fed samples (PERMANOVA, P = 0.003). Multivariate analysis revealed patient as the strongest predictor of the UniFrac distance. Environmental variables did not influence the intrapatient microbial dissimilarity. Host proteomics were similar intrapatient (paired fed-unfed Euclidian distance) and showed a correlation with the UniFrac distance (Spearman rho = 0.71, P < 0.001). Specific proteins and functional clusters were significantly different between paired samples, including lipid metabolism and intracellular trafficking, whereas no difference was seen in innate immune proteins. The microbiome results were validated in a different cohort with similar characteristics. CONCLUSION: We found the host to be the most dominant factor in the structure of the early life small intestinal mucosal microbiome. Nutrient deprivation was associated with specific changes in the host proteome. Further research is needed to better understand this host-microbe-nutrition interaction.

BACKGROUND: For patients with rectal cancer, the utilization of temporary ileostomy (TI) has proven effective in minimizing the occurrence of severe complications post-surgery, such as anastomotic leaks; however, some patients are unable to reverse in time or even develop a permanent stoma (PS). We aimed to determine the preoperative predictors associated with TS failure and develop and validate appropriate predictive models to improve patients' quality of life. METHODS: This research included 403 patients with rectal cancer who underwent temporary ileostomies between January 2017 and December 2021. All patients were randomly divided into either the developmental (70%) or validation (30%) group. The independent risk factors for PS were determined using univariate and multivariate logistic regression analyses. Subsequently, a nomogram was constructed, and the prediction probability was estimated by calculating the area under the curve (AUC) using receiver operating characteristic (ROC) analysis. A calibration plot was used to evaluate the nomogram calibration. RESULTS: Of the 403 enrolled patients, 282 were randomized into the developmental group, 121 into the validation group, and 58 (14.39%) had a PS. The development group consisted of 282 patients, of whom 39 (13.81%) had a PS. The validation group consisted of 121 patients, of whom, 19 (15.70%) had a PS; 37 related factors were analyzed in the study. Multivariate logistic regression analysis demonstrated significant associations between the occurrence of PS and various factors in this patient cohort, including tumor location (OR = 6.631, P = 0.005), tumor markers (OR = 2.309, P = 0.035), American Society of Anesthesiologists (ASA) score (OR = 4.784, P = 0.004), T4 stage (OR = 2.880, P = 0.036), lymph node metastasis (OR = 4.566, P = 0.001), and distant metastasis (OR = 4.478, P = 0.036). Furthermore, a preoperative nomogram was constructed based on these data and subsequently validated in an independent validation group. CONCLUSION: We identified six independent preoperative risk factors associated with PS following rectal cancer resection and developed a validated nomogram with an area under the ROC curve of 0.7758, which can assist surgeons in formulating better surgical options, such as colostomy, for patients at high risk of PS.

OBJECTIVE: Treatment of advanced-stage ovarian cancer contains cytoreductive surgery (CRS) and chemotherapy. Achieving successful CRS (≤ 1 cm residual disease) is prognostically important, but may not be feasible peri-operatively while still risking complications. Therefore, patients' treatment expectations are important to discuss. We investigated patient considerations for interval CRS. METHODS: Patients with advanced-stage ovarian cancer planned for interval CRS completed a questionnaire about the impact of chance of successful CRS, survival benefit and becoming care-dependent on decision-making regarding CRS. The questionnaire included a vignette study, in which patients repeatedly chose between two treatment scenarios with varying levels for chance of successful CRS, survival benefit and risk of complications including stoma. Patient preferences were analyzed, including differences between patients aged < 70 and ≥ 70 years. RESULTS: Among 85 included patients, 31 (37%) patients considered interval CRS worthwhile irrespective of survival benefit and 33 (39%) irrespective of chance of successful surgery. However, 34 patients (41%) considered interval CRS only worthwhile if survival benefit was > 12 months, while 41 (49%) thought so if chance of successful surgery was ≥ 25%. Older patients considered these factors more important. Overall, 27% considered becoming permanently dependent of home care unacceptable. In the vignette study (n = 72) risk of complications and stoma were considered less important than chance of successful CRS and survival benefit. CONCLUSION: Survival benefit, chance of successful surgery and becoming care-dependent are important factors in patient's decision for interval CRS, while risk of complications and stoma are less important. Our results are useful in shared decision-making for interval CRS in ovarian cancer.

OBJECTIVE: To examine the role of bowel diversion and reconstructive surgeries in managing Fournier's gangrene (FG) to facilitate multidisciplinary collaboration between urologists, colorectal and plastic surgery teams. METHODS: A review of the literature was conducted using the databases Medline, Embase, PubMed in June 2023. The review included studies that evaluated the outcomes of FG following reconstructive surgeries or diverting colostomies. RESULTS: The existing evidence suggests that bowel diversion and colostomy formation could reduce the need for further debridement, shorten the time to wound healing, and facilitate skin graft or flap uptake in patients with FG. Additionally, the psychological impact of a stoma was shown not to be a major concern for patients. However, stoma carries a risk of perioperative complications and therefore may prolong the length of hospital stay. In reviewing the evidence for reconstruction in FG, large and deep defects seem to benefit from skin grafts or flaps. Noticeably, burial of testicles in thigh pockets has grown out of favour due to concerns regarding the thermoregulation of the testicles and the psychological impact on patients. CONCLUSION: The use of bowel diversion and reconstructive surgeries in managing FG is case dependent. Therefore, it is important to have close discussions with colorectal and plastic surgery teams when managing FG.
RESUMO
INTRODUCTION: Multiple studies have documented the safety of intestinal anastomosis after resection for necrotizing enterocolitis (NEC). We sought to evaluate a large population of infants with surgical NEC and assess outcomes after primary anastomosis versus enterostomy. METHODS: The Pediatric Health Information System database was used to identify infants with Bell Stage 3 NEC who underwent an intestinal resection for acute disease between 2016 and 2021. Demographics and preoperative physiology were assessed, and nutritional, infectious, and surgical outcomes were analyzed. RESULTS: Two hundred twenty-two infants at 38 children's hospitals were included. Thirty-five (15.8%) were managed with a primary anastomosis. Among infants who underwent a resection within 10 d of their first operative intervention and survived for at least 3 d, a primary anastomosis was used in 26 (13.7%). These patients were older but had similar weight and physiological status at the time of resection as those managed with an enterostomy. The incidence of wound and infectious complications, duration of parenteral nutrition and length of stay were similar after anastomosis or enterostomy. CONCLUSIONS: In a large, geographically heterogenous population of infants with NEC, only 15.8% were managed with a primary anastomosis after intestinal resection. Survivors who underwent resection within 10 d were demographically and physiologically comparable to those who underwent enterostomy and had similar surgical outcomes. While there are clearly indications for enterostomy in some infants with NEC, these data confirm the conclusions of smaller, single-center studies that a primary anastomosis should be considered more frequently.

INTRODUCTION: An intestinal stoma creation is one of the most common surgical procedures. Despite benefits, a stoma can have serious effects on a patient's quality of life. Multiple dimensions of everyday life can be affected such as social life, body image, as well as ability to participate in some religious practices, with some faith groups being disproportionately affected. This study sought to understand the extent to which faith is addressed during these sessions given the integral role it plays for some patients. METHODS: A survey was developed based on literature review and expert consultation. This was distributed to ostomy certified nursing staff, inflammatory bowel disease gastroenterologists and colorectal surgeons caring for patients requiring a permanent stoma at a high-volume academic institution. Follow-up semistructured interviews were conducted to delve deeper into themes identified in the surveys. RESULTS: The overall survey response rate was 57%. Only 35% reported training on how stomas interface with religious practices. Religious services were either rarely or never present during preoperative counseling discussions. During interviews, it was noted that religious beliefs often impact after care but are not always discussed during preoperative sessions. Interviewees found these conversations to be difficult with minimal support or direction on how to navigate them. CONCLUSIONS: Although very important, health-care providers are not including faith-based issues surrounding stomas in perioperative counseling partly due to lack of training or awareness of existing support systems. As our population diversifies, understanding cultural and religious practices that influence care is increasingly important.

INTRODUCTION: In many resource-limited settings, patients with Hirschsprung's Disease (HD) undergo initial diverting colostomy, followed by pull-through, and finally, colostomy closure. This approach allows for decompression of dilated and thickened bowel and improved patient nutritional status. However, this three-stage approach prolongs treatment duration, with significant stoma morbidity, costs, and impact on quality of life. Our aim was to determine whether pull-through for HD can safely be performed with simultaneous stoma closure, reducing treatment approach from three to two stages. METHODS: Children with HD and diverting colostomy were prospectively followed as they underwent pull-through with simultaneous stoma closure. Their in-hospital course and 3-mo outpatient course were assessed for postoperative complications. Patients with total colonic HD, redo pull-through, and residual dilated colon were excluded from the study. RESULTS: Of the 20 children, 17 were male (n = 17, 85%). All patients had rectosigmoid HD. The median weight, age at colostomy formation, and age at pull-through were 11.05 kg (interquartile range [IQR] 10-12.75), 0.9 y (IQR 0.25-2.8), and 2.08 y (IQR 1.28-2.75), respectively. Mean duration with colostomy before pull-through was 1.1 y (standard deviation 1.51). Median hospital length of stay was 6 d (IQR 5-7). Early complications included anastomotic leak (n = 1), perianal skin excoriation (n = 2), surgical site skin infection (n = 3), and fascial dehiscence (n = 1). Longer-term complications included stricture (n = 1, 5%) and enterocolitis (n = 2, 10%). CONCLUSIONS: In this small case series, we have demonstrated that pull-through with simultaneous stoma closure can be safely performed in resource-constrained settings. Further studies are needed to understand the quality of life and economic impact of this change in management for HD patients.

BACKGROUND: Clostridium difficile infection (CDI) has been described in the early post-operative phase after stoma reversal. This systematic review aimed to describe the incidence of CDI after stoma reversal and to identify pre-operative variables correlated with an increased risk of infection. METHODS: A systematic review of the literature was conducted according to the PRISMA guidelines in March 2024. Manuscripts were included if reported at least one patient with CDI-associated diarrhoea following stoma reversal (colostomy/ileostomy). The primary outcome of interest was the incidence of CDI; the secondary outcome was the comparison of clinical variables (age, sex, time to stoma reversal, neo-adjuvant and adjuvant therapies after index colorectal procedure) in CDI-positive versus CDI-negative patients. A meta-analysis was performed when at least three studies reported on those variables. RESULTS: Out of 43 eligible manuscripts, 1 randomized controlled trial and 10 retrospective studies were selected, including 17,857 patients (2.1% CDI). Overall, the mean age was 64.3 ± 11.6 years in the CDI group and 61.5 ± 12.6 years in the CDI-negative group (p = 0.51), with no significant difference in sex (p = 0.34). Univariable analyses documented that the mean time to stoma reversal was 53.9 ± 19.1 weeks in CDI patients and 39.8 ± 15.0 weeks in CDI-negative patients (p = 0.40) and a correlation between neo-adjuvant and adjuvant treatments with CDI (p < 0.001). A meta-analysis was performed for time to stoma reversal, age, sex, and neo-adjuvant therapies disclosing no significant differences for CDI (stoma delay, MD 11.59; 95%CI 24.32-1.13; age, MD 0.97; 95%CI 2.08-4.03; sex, OR1.11; 95%CI 0.88-1.41; neo-adjuvant, OR0.81; 95%CI 0.49-1.35). Meta-analysis including patients who underwent adjuvant therapy evidenced a higher risk of CDI (OR 2.88; 95%CI 1.01-8.17, p = 0.11). CONCLUSION: CDI occurs in approximately 2.1% of patients after stoma reversal. Although a trend of increased delay in stoma reversal and a correlation with chemotherapy were documented in CDI patients, the use of adjuvant therapy was the only possible risk factor documented on meta-analysis. PROSPERO REGISTRATION NUMBER: CRD42023484704.

AIM: Approximately 4000 patients in the UK have an emergency intestinal stoma formed each year. Stoma-related complications (SRCs) are heterogeneous but have previously been subcategorized into early or late SRCs, with early SRCs generally occurring within 30 days postoperatively. Early SRCs include skin excoriation, stoma necrosis and high output, while late SRCs include parastomal hernia, retraction and prolapse. There is a paucity of research on specific risk factors within the emergency cohort for development of SRCs. This paper aims to describe the incidence of SRCs after emergency intestinal surgery and to identify potential risk factors for SRCs within this cohort. METHOD: Consecutive patients undergoing emergency formation of an intestinal stoma (colostomy, ileostomy or jejunostomy) were identified prospectively from across three acute hospital sites over a 3-year period from the ELLSA (Emergency Laparotomy and Laparoscopic Scottish Audit) database. All patients were followed up for a minimum of 1 year. A multivariate logistic regression model was used to identify risk factors for early and late SRCs. RESULTS: A total of 455 patients were included (median follow-up 19 months, median age 64 years, male:female 0.52, 56.7% ileostomies). Early SRCs were experienced by 54.1% of patients, while 51% experienced late SRCs. A total of 219 patients (48.1%) had their stoma sited preoperatively. Risk factors for early SRCs included end ileostomy formation [OR 3.51 (2.24-5.49), p < 0.001], while preoperative stoma siting was found to be protective [OR 0.53 (0.35-0.83), p = 0.005]. Patient obesity [OR 3.11 (1.92-5.03), p < 0.001] and reoperation for complications following elective surgery [OR 4.18 (2.01-8.69), p < 0.001] were risk factors for late SRCs. CONCLUSION: Stoma-related complications after emergency surgery are common. Preoperative stoma siting is the only truly modifiable risk factor to reduce SRCs, and further research should be aimed at methods of improving the frequency and accuracy of this in the emergency setting.

AIM: The aim of this work was to compare adjustment between those with a new temporary or permanent ostomy in a cohort of Australian adults. METHOD: This is a multicentre, longitudinal observational study. Ostomy adjustment was measured using the Ostomy Adjustment Inventory (OAI-23) at six possible time points ending at 9 months postsurgery or at the time of ostomy closure in those with a temporary stoma. The OAI-23 includes four domains: anger, acceptance, anxious preoccupation and social engagement. RESULTS: Eligibility criteria were met by 1230 patients, with 849 (69%) recruited and consented. Of these, 108 were excluded as their surgery did not result in the formation of an ostomy and a further 41 were excluded due to there being no data on ostomy type (temporary or permanent). This left a study population of 700, of whom 397 had a temporary and 303 a permanent ostomy. Only small differences were observed between the temporary and permanent ostomy groups at most time points within the four OAI-23 domains. There were no statistically significant differences found beyond 2 weeks postdischarge and the differences were of small size. While no difference was found between the groups in the domain of anxious preoccupation, both groups demonstrated an increase in anxious preoccupation over time. Neither group regained their presurgery confidence to attend social engagements. CONCLUSION: We found only minor differences in adjustment in those with a new temporary ostomy compared with a new permanent ostomy. Both groups demonstrated increasing anxious preoccupation and problems with social engagement. This suggests that access to education, training and support should be equitable between these two groups in clinical practice, and needs to incorporate a focus on psychological as well as physical outcomes.

AIM: Some patients with inflammatory bowel disease (IBD) require subtotal colectomy (STC) with ileostomy. The recent literature reports a significant number of patients who do not undergo subsequent surgery and are resigned to living with a definitive stoma. The aim of this work was to analyse the rate of definitive stoma and the cumulative incidence of secondary reconstructive surgery after STC for IBD in a large national cohort study. METHOD: A national retrospective study (2013-2021) was conducted on prospectively collected data from the French Medical Information System Database (PMSI). All patients undergoing STC in France were included. The association between definitive stoma and potential risk factors was studied using univariate and multivariate analyses. RESULTS: A total of 1860 patients were included (age 45 ± 9 years; median follow-up 30 months). Of these, 77% (n = 1442) presented with ulcerative colitis. Mortality and morbidity at 90 days after STC were 5% (n = 100) and 47% (n = 868), respectively. Reconstructive surgery was identified in 1255 patients (67%) at a mean interval of 7 months from STC. Seveny-four per cent (n = 932) underwent a completion proctectomy with ileal pouch anal anastomosis and 26% (n = 323) an ileorectal anastomosis. Six hundred and five (33%) patients with a definitive stoma had an abdominoperineal resection (n = 114; 19%) or did not have any further surgical procedure (n = 491; 81%). Independent risk factors for definitive stoma identified in multivariate analysis were older age, Crohn's disease, colorectal neoplasia, postoperative complication after STC, laparotomy and a low-volume hospital. CONCLUSION: We found that 33% of patients undergoing STC with ileostomy for IBD had definitive stoma. Modifiable risk factors for definitive stoma were laparotomy and a low-volume hospital.

AIM: Temporary stoma formation remains a common part of modern-day colorectal surgical operations. At the time of reversal, a second procedure is required when the bowel is anastomosed and the musculature is closed. The rate of incisional hernia at these sites is 30%-35% with conventional suture closure. Mesh placement at this site is therefore an attractive option to reduce hernia risk, particularly as new mesh types, such as biosynthetic meshes, are available. The aim of this work was to conduct a systematic review and meta-analysis assessing the use of mesh for prophylaxis of incisional hernia at stoma closure and to explore the outcome measures used by each of the included studies to establish whether they are genuinely patient-centred. METHOD: This is a systematic review and meta-analysis assessing the published literature regarding the use of mesh at stoma site closure operations. Comprehensive literature searches of major electronic databases were performed by an information specialist. Screening of search results was undertaken using standard systematic review principles. Data from selected studies were input into an Excel file. Meta-analysis of the results of included studies was conducted using RevMan software (v.5.4). Randomized controlled trial (RCT) and non-RCT data were analysed separately. RESULTS: Eleven studies with a total of 2008 patients were selected for inclusion, with various mesh types used. Of the included studies, one was a RCT, seven were nonrandomized comparative studies and three were case series. The meta-analysis of nonrandomized studies shows that the rate of incisional hernia was lower in the mesh reinforcement group compared with the suture closure group (OR 0.21, 95% CI 0.12-0.37) while rates of infection and haematoma/seroma were similar between groups (OR 0.7, 95% CI 0.41-1.21 and OR 1.05, 95% CI 0.63-1.80, respectively). The results of the RCT were in line with those of the nonrandomized studies. CONCLUSION: Current evidence indicates that mesh is safe and reduces incisional hernia. However, this is not commonly adopted into current clinical practice and the literature has minimal patient-reported outcome measures. Future work should explore the reasons for such slow adoption as well as the preferences of patients in terms of outcome measures that matter most to them.

AIM: Diverting stomas are routinely used in restorative surgery following total mesorectal exicision (TME) for rectal cancer to mitigate the clinical risks of anastomotic leakage (AL). However, routine diverting stomas are associated with their own complication profile and may not be required in all patients. A tailored approach based on personalized risk of AL and selective use of diverting stoma may be more appropriate. The aim of the TAilored SToma policY (TASTY) project was to design and pilot a standardized, tailored approach to diverting stoma in low rectal cancer. METHOD: A mixed-methods approach was employed. Phase I externally validated the anastomotic failure observed risk score (AFORS). We compared the observed rate of AL in our cohort to the theoretical, predicted risk of the AFORS score. To identify the subset of patients who would benefit from early closure of the diverting stoma using C-reactive protein (CRP) we calculated the Youden index. Phase II designed the TASTY approach based on the results of Phase I. This was evaluated within a second prospective cohort study in patients undergoing TME for rectal cancer between April 2018 and April 2020. RESULTS: A total of 80 patients undergoing TME surgery for rectal cancer between 2016 and 2018 participated in the external validation of the AFORS score. The overall observed AL rate in this cohort of patients was 17.5% (n = 14). There was a positive correlation between the predicted and observed rates of AL using the AFORS score. Using ROC curves, we calculated a CRP cutoff value of 115 mg/L on postoperative day 2 for AL with a sensitivity of 86% and a negative predictive value of 96%. The TASTY approach was designed to allocate patients with a low risk AFORS score to primary anastomosis with no diverting stoma and high risk AFORS score patients to a diverting stoma, with early closure at 8-14 days, if CRP values and postoperative CT were satisfactory. The TASTY approach was piloted in 122 patients, 48 (39%) were identified as low risk (AFORS score 0-1) and 74 (61%) were considered as high risk (AFORS score 2-6). The AL rate was 10% in the low-risk cohort of patient compared to 23% in the high-risk cohort of patients, p = 0.078 The grade of Clavien-Dindo morbidity was equivalent. The incidence of major LARS was lowest in the no stoma cohort at 3 months (p = 0.014). CONCLUSION: This study demonstrates the feasibility and safety of employing a selective approach to diverting stoma in patients with a low anastomosis following TME surgery for rectal cancer.
RESUMO
AIM: Literature on nationwide long-term permanent stoma rates after rectal cancer resection in the minimally invasive era is scarce. The aim of this population-based study was to provide more insight into the permanent stoma rate with interhospital variability (IHV) depending on surgical technique, with pelvic sepsis, unplanned reinterventions and readmissions as secondary outcomes. METHOD: Patients who underwent open or minimally invasive resection of rectal cancer (lower border below the sigmoid take-off) in 67 Dutch centres in 2016 were included in this cross-sectional cohort study. RESULTS: Among 2530 patients, 1470 underwent a restorative resection (58%), 356 a Hartmann's procedure (14%, IHV 0%-42%) and 704 an abdominoperineal resection (28%, IHV 3%-60%). Median follow-up was 51 months. The overall permanent stoma rate at last follow-up was 50% (IHV 13%-79%) and the unintentional permanent stoma rate, permanent stoma after a restorative procedure or an unplanned Hartmann's procedure, was 11% (IHV 0%-29%). A total of 2165 patients (86%) underwent a minimally invasive resection: 1760 conventional (81%), 170 transanal (8%) and 235 robot-assisted (11%). An anastomosis was created in 59%, 80% and 66%, with corresponding unintentional permanent stoma rates of 12%, 24% and 14% (p = 0.001), respectively. When corrected for age, American Society of Anesthesiologists classification, cTNM, distance to the anorectal junction and neoadjuvant (chemo)radiotherapy, the minimally invasive technique was not associated with an unintended permanent stoma (p = 0.071) after a restorative procedure. CONCLUSION: A remarkable IHV in the permanent stoma rate after rectal cancer resection was found. No beneficial influence of transanal or robot-assisted laparoscopy on the unintentional permanent stoma rate was found, although this might be caused by the surgical learning curve. A reduction in IHV and improving preoperative counselling for decision-making for restorative procedures are required.

AIM: Although proximal faecal diversion is standard of care to protect patients with high-risk colorectal anastomoses against septic complications of anastomotic leakage, it is associated with significant morbidity. The Colovac device (CD) is an intraluminal bypass device intended to avoid stoma creation in patients undergoing low anterior resection. A preliminary study (SAFE-1) completed in three European centres demonstrated 100% protection of colorectal anastomoses in 15 patients, as evidenced by the absence of faeces below the CD. This phase III trial (SAFE-2) aims to evaluate the safety and effectiveness of the CD in a larger cohort of patients undergoing curative rectal cancer resection. METHODS: SAFE-2 is a pivotal, multicentre, prospective, open-label, randomized, controlled trial. Patients will be randomized in a 1:1 ratio to either the CD arm or the diverting loop ileostomy arm, with a recruitment target of 342 patients. The co-primary endpoints are the occurrence of major postoperative complications within 12 months of index surgery and the effectiveness of the CD in reducing stoma creation rates. Data regarding quality of life and patient's acceptance and tolerance of the device will be collected. DISCUSSION: SAFE-2 is a multicentre randomized, control trial assessing the efficacy and the safety of the CD in protecting low colorectal anastomoses created during oncological resection relative to standard diverting loop ileostomy. TRIAL REGISTRATION: NCT05010850.

PURPOSE: To explore whether profiles derived from self-reported quality of life were associated with receipt of, and interest in, advice from a healthcare professional in people with a stoma. METHODS: Secondary analysis of cross-sectional national survey data from England of 4487 people with a stoma from colorectal cancer. The survey assessed quality of life using various scales, receipt and interest in various forms of advice, and physical activity. A three-step latent profile analysis was conducted to determine the optimum number of profiles. Multinomial regression explored factors associated with profile membership. A series of logistic regression models examined whether profile membership was associated with interest in advice. RESULTS: Five profiles were identified; 'consistently good quality of life', 'functional issues', 'functional and financial issues', 'low quality of life' and 'supported but struggling'. Individuals in the 'functional and financial issues' and 'low quality of life' profiles were more likely to have received financial advice compared to the 'consistently good quality of life' profile. When compared to the 'consistently good quality of life' profile, all other profiles were more likely to report wanting advice across a range of areas, with the strongest associations in the 'low quality of life' profile. CONCLUSION: Findings indicate that people with a stoma are not a homogenous group in terms of quality of life. Participants in profiles with quality of life concerns report wanting more advice across various categories but findings suggest there is scope to explore how this can be tailored or adapted to specific groups.

PURPOSE: Although there is a growing emphasis on supportive care for cancer patients, those with colorectal cancer (CRC) who have ostomies require special attention in terms of their physical, psychological, spiritual, and social needs. However, there has been a lack of significant progress in meeting the supportive care needs of CRC survivors with ostomies. To bridge this gap, we conducted a prospective longitudinal study to track the trends in supportive care needs among CRC survivors with ostomies and identify any predictors over 6-month period. METHODS: A prospective longitudinal study was conducted at the wound and stoma clinic of Dalian University Affiliated Xinhua Hospital, focusing on CRC survivors with ostomies. A total of 143 participants completed self-report questionnaires on the 34-item Short-Form Supportive Care Needs Survey (SCNS-SF34-C (Mandarin)) and stoma complications at the first, third, and sixth month after surgery. ANOVA with repeated measure was utilized to assess the course of supportive care needs, with Generalized Estimating Equation (GEE) applied to identify predictors of SCNS. RESULTS: The supportive care needs and five dimensions scores were statistically significant at three time points (P < 0.05). The ratings of patients at the first, third, and sixth month after surgery revealed a decreasing trend in the scores for patient care and support, psychological needs, physical and daily living needs, and health system and information needs. However, the score for sexual needs showed an increased tendency. Higher levels supportive care needs were generally connected with a short duration after ostomy, high income level, resident medical insurance, spouse caregiver, other chronic disease, and stoma complications. CONCLUSIONS: Survivors' supportive care needs showed a dynamic trend over 6 months after surgery. Through three rounds, the primary needs were health system and information needs. It is recommended to integrate interdisciplinary health professionals and establish a comprehensive support and care system to effectively meet the diverse needs at different stages. Priority should be given to individuals with ostomies during the first and third month after surgery, particularly those with higher income levels, employee medical insurance, spouse caregivers, other chronic diseases, and stoma complications.
