Abstract
AIM Organ preservation strategies for patients with rectal cancer are increasingly common. In appropriately selected patients, local excision (LE) of pT1 cancers can reduce morbidity without compromising cancer-related outcomes. However, determining the need for completion surgery after LE can be challenging, and it is unknown if prior LE compromises subsequent total mesorectal excision (TME). The aim of this study is to describe the current management of patients with pT1 rectal cancers. METHOD This is a retrospective national cohort study of the Danish Colorectal Cancer Group database, including patients with newly diagnosed pT1 cancers between 2016 and 2020. Patients were stratified according to treatment into LE alone, completion TME after LE or upfront TME. The treatment and outcomes of these groups were compared. RESULTS A total of 1056 patients were included. Initial LE was performed in 715 patients (67.7%), of whom 194 underwent completion TME (27.1%). The remaining 341 patients underwent upfront TME (32.3%). Patients undergoing LE alone were more likely to be male with low rectal cancers and greater comorbidity. No differences in specimen quality or perioperative outcomes were noted between patients undergoing completion or upfront TME. Eighty-five patients (15.9%) had lymph node metastases (LNM). Pathological risk factors poorly discriminated between patients with and without LNM, with similar rates seen in patients with zero (14.1%), one (12.0%) or two (14.4%) risk factors. CONCLUSION LE is a key component of the treatment of pT1 rectal cancer and does not appear to affect the outcomes of completion TME. Patient selection for completion TME remains a major challenge, with current stratification methods appearing to be inadequate.

Abstract
BACKGROUND The Delphi consensus identified 8 symptoms and 8 consequences as the highest priorities for defining low anterior resection syndrome. OBJECTIVE To describe an exploratory scoring instrument correlating the Delphi consensus on low anterior resection syndrome with functional and quality-of-life scores following intersphincteric resection for ultralow rectal cancer. DESIGN This was a prospective pilot study. In accordance with the Wexner incontinence score, 5 frequency responses ranging from never (score 0) to always (score 4) were used to measure the severity of symptom- and consequence-specific variables. SETTINGS Colorectal surgery referral center. PATIENTS Among 161 eligible patients, 137 participants (85%) completed an electronic self-assessment survey regarding function and quality of life at scheduled follow-up, including 3 to 6, 12, and ≥24 months after ileostomy reversal. MAIN OUTCOME MEASURES Outcome measures included patient-reported severity of the identified priorities, and their correlation with condition-specific quality of life. RESULTS The most frequent symptom and consequence were "emptying difficulties" and "dissatisfaction with the bowels," respectively. Aside from "emptying difficulties," the proportions of negative symptom domains increased after reversal. In particular, neither the frequency responses nor the severity scores of "emptying difficulties" differed between groups. The percentages of "always" selection for consequence domains improved at 12-month follow-up, whereas a higher rate was observed at 24 months, except for "toilet dependence" and "dissatisfaction with the bowels." We found significant improvements in the summary score of the Fecal Incontinence Quality-of-Life Scale ( p = 0.04) and our exploratory instrument ( p = 0.009) but not in functional scores measured by traditional questionnaires. Furthermore, the condition-specific quality of life strongly correlated with the Delphi consensus severity score ( rs = -0.73). LIMITATIONS Single-institution data and limited sample size. CONCLUSIONS The important priorities identified by the Delphi consensus might enable a comprehensive overview and a better assessment of low anterior resection syndrome after intersphincteric resection.

Aparte de las "dificultades de vaciado", las proporciones de dominios de síntomas negativos aumentaron después de la reversión. En particular, tanto las respuestas de frecuencia como las puntuaciones de gravedad de las "dificultades para vaciar" no difirieron entre los grupos. Los porcentajes de "opción siempre" para los dominios de consecuencias mejoraron a los 12 meses de seguimiento, mientras que se observó una tasa más alta a los 24 meses después, excepto para "dependencia del baño" e "insatisfacción con los intestinos". Encontramos mejoras significativas en la puntuación resumida de la Escala de calidad de vida de incontinencia fecal ( p = 0,04) y nuestro instrumento exploratorio ( p = 0,009), pero no en las puntuaciones funcionales medidas con los cuestionarios tradicionales. Además, la calidad de vida específica de la condición se correlacionó fuertemente con la puntuación de gravedad del consenso Delphi (rs = -0,73).LIMITACIONES:Datos de una sola institución y tamaño de muestra limitado.CONCLUSIONES:Las importantes prioridades identificadas por el consenso Delphi podrían permitir una visión global y una mejor evaluación del síndrome de resección anterior baja después de la resección interesfintérica.

The Effect of a Temporary Stoma on Long-term Functional Outcomes Following Surgery for Rectal Cancer. Dis Colon Rectum 2024; 67:291-301.

Abstract
BACKGROUND Patients with rectal cancer may undergo surgical resection with or without a temporary stoma. OBJECTIVE This study primarily aimed to compare long-term functional outcomes between patients with and without a temporary stoma after surgery for rectal cancer. The secondary aim was to investigate the effect of time to stoma reversal on functional outcomes. DESIGN This was a multicenter, cross-sectional study. SETTINGS This study was conducted at 7 Dutch hospitals. PATIENTS Included were patients who had undergone rectal cancer surgery (2009-2015). Excluded were deceased patients, who were deceased, had a permanent stoma, or had intellectual disability. MAIN OUTCOME MEASURES Functional outcomes were measured using the Rome IV criteria for constipation and fecal incontinence and the low anterior resection syndrome score. RESULTS Of 656 patients, 32% received a temporary ileostomy and 20% a temporary colostomy (86% response). Follow-up was at 56 (interquartile range, 38.5-79) months. Patients who had a temporary ileostomy experienced less constipation, more fecal incontinence, and more major low anterior resection syndrome than those without a temporary stoma. Patients who had a temporary colostomy experienced more major low anterior resection syndrome than those without a temporary stoma. A temporary ileostomy or colostomy was not associated with constipation or fecal incontinence after correction for confounding factors (eg, anastomotic height, anastomotic leakage, radiotherapy). Time to stoma reversal was not associated with constipation, fecal incontinence, or major low anterior resection syndrome. LIMITATIONS Cross-sectional design. CONCLUSIONS Although patients with a temporary ileostomy or colostomy have worse functional outcomes in the long term, it seems that the reason for creating a temporary stoma, rather than the stoma itself, underlies this phenomenon. Time to reversal of a temporary stoma does not influence functional outcomes. See Video Abstract .

El seguimiento fue de 56.0 (RIQ 38.5-79.0) meses. Los pacientes a los que se les realizó una ileostomía temporal experimentaron menos estreñimiento, más incontinencia fecal y más LARS mayor que los pacientes sin un estoma temporal. Los pacientes que tuvieron una colostomía temporal experimentaron más LARS mayor que los pacientes sin un estoma temporal. Una ileostomía o colostomía temporal no se asoció con estreñimiento o incontinencia fecal después de la corrección de factores de confusión (p. ej., altura anastomótica, fuga anastomótica, radioterapia). El tiempo hasta la reversión del estoma no se asoció con estreñimiento, incontinencia fecal o LARS mayor.LIMITACIONES:El presente estudio está limitado por su diseño transversal.CONCLUSIONES:Aunque los pacientes con una ileostomía o colostomía temporal tienen peores resultados funcionales a largo plazo, parece que la razón para crear un estoma temporal, más que el estoma en sí, se asocia a este fenómeno. El tiempo hasta la reversión de un estoma temporal no influye en los resultados funcionales. (Traducción-Dr. Jorge Silva Velazco ).

Abstract
BACKGROUND & AIMS The benefit of radiotherapy for rectal cancer is based largely on a balance between a decrease in local recurrence and an increase in bowel dysfunction. Predicting postoperative disability is helpful for recovery plans and early intervention. We aimed to develop and validate a risk model to improve the prediction of major bowel dysfunction after restorative rectal cancer resection with neoadjuvant radiotherapy using perioperative features. METHODS Eligible patients more than 1 year after restorative resection following radiotherapy were invited to complete the low anterior resection syndrome (LARS) score at 3 national hospitals in China. Clinical characteristics and imaging parameters were assessed with machine learning algorithms. The post-radiotherapy LARS prediction model (PORTLARS) was constructed by means of logistic regression on the basis of key factors with proportional weighs. The accuracy of the model for major LARS prediction was internally and externally validated. RESULTS A total of 868 patients reported a mean LARS score of 28.4 after an average time of 4.7 years since surgery. Key predictors for major LARS included the length of distal rectum, anastomotic leakage, proximal colon of neorectum, and pathologic nodal stage. PORTLARS had a favorable area under the curve for predicting major LARS in the internal dataset (0.835; 95% CI, 0.800-0.870, n = 521) and external dataset (0.884; 95% CI, 0.848-0.921, n = 347). The model achieved both sensitivity and specificity >0.83 in the external validation. In addition, PORTLARS outperformed the preoperative LARS score for prediction of major events. CONCLUSIONS PORTLARS could predict major bowel dysfunction after rectal cancer resection following radiotherapy with high accuracy and robustness. It may serve as a useful tool to identify patients who need additional support for long-term dysfunction in the early stage. CLINICALTRIALS gov, number NCT05129215.
