Predictors for temporary stomas non-closure among non-metastatic rectal cancer patients undergoing curative resection: a retrospective analysis. World J Surg Oncol 2024; 22:124. [PMID: 38715036 PMCID: PMC11075260 DOI: 10.1186/s12957-024-03403-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Accepted: 05/02/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND The primary treatment for non-metastatic rectal cancer is curative resection. However, sphincter-preserving surgery may lead to complications. This study aims to develop a predictive model for stoma non-closure in rectal cancer patients who underwent curative-intent low anterior resection. METHODS Consecutive patients diagnosed with non-metastatic rectal cancer between January 2005 and December 2017, who underwent low anterior resection, were retrospectively included in the Chang Gung Memorial Foundation Institutional Review Board. A comprehensive evaluation and analysis of potential risk factors linked to stoma non-closure were performed. RESULTS Out of 956 patients with temporary stomas, 10.3% (n = 103) experienced non-closure primarily due to cancer recurrence and anastomosis-related issues. Through multivariate analysis, several preoperative risk factors significantly associated with stoma non-closure were identified, including advanced age, anastomotic leakage, positive nodal status, high preoperative CEA levels, lower rectal cancer presence, margin involvement, and an eGFR below 30 mL/min/1.73m2. A risk assessment model achieved an AUC of 0.724, with a cutoff of 2.5, 84.5% sensitivity, and 51.4% specificity. Importantly, the non-closure rate could rise to 16.6% when more than two risk factors were present, starkly contrasting the 3.7% non-closure rate observed in cases with a risk score of 2 or below (p < 0.001). CONCLUSION Prognostic risk factors associated with the non-closure of a temporary stoma include advanced age, symptomatic anastomotic leakage, nodal status, high CEA levels, margin involvement, and an eGFR below 30 mL/min/1.73m2. Hence, it is crucial for surgeons to evaluate these factors and provide patients with a comprehensive prognosis before undergoing surgical intervention.

Abstract
PURPOSE Defunctioning ileostomies are often performed during rectal cancer surgery. However, stomas are sometimes associated with complications, while 20-30% of them are never reversed. Additionally, ileostomy closure can have associated morbidity, with rates as high as 45%, with the respective literature evidence being scarce and conflicting. Thus, we evaluated the stoma reversal outcomes and the risk factors for non-closure after rectal cancer surgery. METHODS This is a retrospective analysis of a prospectively collected database of all patients who had a defunctioning ileostomy at the time of resection for rectal cancer. All operations were performed by the same surgical team. A multivariable regression model was implemented. RESULTS In this study, 129 patients (male: 68.2%, female: 31.8%) were included. Ileostomy formation was associated with a total of 31% complication rate. Eventually 73.6% of the stomas were reversed at a mean time to closure of 26.6 weeks, with a morbidity of 13.7%. Non-reversal of ileostomy was correlated with neoadjuvant CRT (OR: 0.093, 95% CI: 0.012-0.735), anastomotic leakage (OR: 0.107, 95% CI: 0.019-0.610), and lymph node yield (OR: 0.946, 95% CI: 0.897-0.998). Time to reversal was affected by the N status, the LNR, the need for adjuvant chemotherapy, and the histologic grade. CONCLUSION In patients with rectal cancer resections, defunctioning stoma closure rate and time to closure were associated with several perioperative and pathological outcomes.

Abstract
BACKGROUND Anastomotic stricture/stenosis (AS) is an alarming complication after colorectal surgery, and there is still no recognized definition for AS. This study aimed to determine the status and change of AS after rectal surgery using a special AS definition and grading system, discuss various risk factors for AS. METHODS This study included patients with rectal cancer who underwent total mesorectal excision between May 2014 and May 2021. A five-degree special AS definition and grading system was used to determine AS status, and clinical outcomes and risk factors for AS were investigated. RESULTS A total of 473 patients were enrolled in this study. Univariate and multivariate analyses of patient-related and technical risk factors for AS were performed 3 months postoperatively. For univariate analysis, female sex was a lower risk factor for AS. Defunctioning stoma, neoadjuvant chemoradiotherapy, chemotherapy, and anastomotic leakage were higher risk factors for AS (all p < 0.05). For multivariate analysis, only neoadjuvant chemoradiotherapy, chemotherapy, and anastomotic leakage were still higher risk factors for AS (all p < 0.05). CONCLUSIONS Through a special AS definition and grading system's evaluation, we noted that neoadjuvant chemoradiotherapy, chemotherapy, and anastomotic leakage were the higher risk factors for AS.

Abstract
Objective The purpose of this study was to develop a machine learning model to identify preoperative and intraoperative high-risk factors and to predict the occurrence of permanent stoma in patients after total mesorectal excision (TME). Methods A total of 1,163 patients with rectal cancer were included in the study, including 142 patients with permanent stoma. We collected 24 characteristic variables, including patient demographic characteristics, basic medical history, preoperative examination characteristics, type of surgery, and intraoperative information. Four machine learning algorithms including extreme gradient boosting (XGBoost), random forest (RF), support vector machine (SVM) and k-nearest neighbor algorithm (KNN) were applied to construct the model and evaluate the model using k-fold cross validation method, ROC curve, calibration curve, decision curve analysis (DCA) and external validation. Results The XGBoost algorithm showed the best performance among the four prediction models. The ROC curve results showed that XGBoost had a high predictive accuracy with an AUC value of 0.987 in the training set and 0.963 in the validation set. The k-fold cross-validation method was used for internal validation, and the XGBoost model was stable. The calibration curves showed high predictive power of the XGBoost model. DCA curves showed higher benefit rates for patients who received interventional treatment under the XGBoost model. The AUC value for the external validation set was 0.89, indicating that the XGBoost prediction model has good extrapolation. Conclusion The prediction model for permanent stoma in patients with rectal cancer derived from the XGBoost machine learning algorithm in this study has high prediction accuracy and clinical utility.

Protective ileostomy increased the incidence of rectal stenosis after anterior resection for rectal cancer. Radiat Oncol 2022; 17:93. [PMID: 35549964 PMCID: PMC9097119 DOI: 10.1186/s13014-022-02031-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Accepted: 03/03/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND In most of the views, rectal stenosis after anterior resection for rectal cancer results from pelvic radiotherapy. However, patients without receiving radiotherapy also suffer stenosis. In this study, we evaluated the factors associated with rectal stenosis after anterior rectal resection (ARR). METHODS We conducted a retrospective study with ARR patients who underwent neoadjuvant chemoradiotherapy and the patients without radiotherapy. Patients who received watch and wait strategy with a clinical complete response after chemoradiotherapy were also included. Patients with colonoscopy follow-up were included for further analyses; 439 patients who underwent neoadjuvant chemoradiotherapy; 545 patients who received ARR without radiotherapy and 33 patients who received watch and wait strategy. Stenosis was diagnosed when a 12-mm diameter colonoscopy could not be passed through the rectum. Univariate and multivariate logistic regression analyses were performed to identify variables associated with rectal stenosis. RESULTS According to the multivariate analysis in patients receiving ARR, both protective stoma and preoperative radiotherapy affected the occurrence of stenosis, with the odds ratios (ORs) of 3.375 and 2.251, respectively. According to the multivariate analysis, a preventive ileostomy was the only factor associated with stenosis both in patients receiving preoperative radiotherapy and without radiotherapy. Non-reversal ileostomy and long time between ileostomy and restoration increased the possibility of stenosis. In 33 patients who received watch and wait strategy, only one patient (3%) experienced stenosis. CONCLUSION Both surgery and radiotherapy are risk factors for rectal stenosis in rectal cancer patients. Compared to preoperative radiotherapy, a protective ileostomy is a more critical factor associated with rectal stenosis.

Cumulative Incidence and Risk Factors of Permanent Stoma After Intersphincteric Resection for Ultralow Rectal Cancer. Dis Colon Rectum 2022; 65:66-75. [PMID: 34882629 DOI: 10.1097/dcr.0000000000002036] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/08/2023]
Abstract
BACKGROUND A permanent stoma is an unintended consequence that cannot be avoided completely after intersphincteric resection for ultralow rectal cancer. Unfortunately, its incidence and risk factors have been poorly defined. OBJECTIVE The objective was to determine the cumulative incidence and risk factors of permanent stoma after intersphincteric resection for ultralow rectal cancer. DESIGN This study was a retrospective analysis of prospectively collected data. SETTINGS This study was conducted at a colorectal surgery referral center. PATIENTS A total of 185 consecutive patients who underwent intersphincteric resection with diverting ileostomy from 2011 to 2019 were included. MAIN OUTCOME MEASURES The primary outcome was the incidence of and risk factors for the permanent stoma. The secondary outcome included differences in stoma formation between patients with partial, subtotal, and total intersphincteric resection. RESULTS After a median follow-up of 40 months (range, 6-107 months), 26 of 185 patients eventually required a permanent stoma, accounting for a 5-year cumulative incidence of 17.4%. The causes of permanent stoma were anastomotic morbidity (46.2%, 12/26), local recurrence (19.2%, 5/26), distant metastasis (19.2%, 5/26), fecal incontinence (3.8%, 1/26), perioperative mortality (3.8%, 1/26), patients' refusal (3.8%, 1/26), and poor general condition (3.8%, 1/26). Although the incidence of permanent stoma was significantly different between the intersphincteric resection groups (partial vs subtotal vs total: 8.3% vs 20% vs 25.8%, p = 0.02), it was not an independent predictor of stoma formation. Multivariate analysis demonstrated that anastomotic leakage (OR = 5.29; p = 0.001) and anastomotic stricture (OR = 5.13; p = 0.002) were independently predictive of permanent stoma. LIMITATIONS This study was limited by its retrospective nature and single-center data. CONCLUSIONS The 5-year cumulative incidence of permanent stoma was 17.4%. Anastomotic complications were identified as risk factors. Patients should be informed of the risks and benefits when contemplating the ultimate sphincter-sparing surgery. It might be preferable to decrease the probability of permanent stoma by further minimizing anastomotic complications. See Video Abstract at http://links.lww.com/DCR/B704. INCIDENCIA ACUMULADA Y FACTORES DE RIESGO DE ESTOMA PERMANENTE DESPUS DE UNA RESECCIN INTERESFNTRICA EN CNCER RECTAL ULTRA BAJO ANTECEDENTES:La necesidad de efectuar un estoma permanente es la consecuencia no intencional e inevitable por completo después de una resección interesfintérica en presencia de un cáncer rectal ultra bajo. Desafortunadamente, la incidencia y los factores de riesgo se han definido en una forma limitada.OBJETIVO:El objetivo fue determinar la incidencia acumulada y los factores de riesgo para la necesidad de efectuar un estoma permanente después de la resección intersfintérica de un cáncer rectal ultra bajo.DISEÑO:El presente estudio es un análisis retrospectivo de la información obtenida.ESCENARIO:Centro de referencia de cirugía colo-rectal.PACIENTES:Se incluyeron un total de 185 pacientes consecutivos que se sometieron a resección intersfintérica de un cáncer rectal ultra bajo con ileostomía de derivación de 2011 a 2019.MEDICION DE RESULTADOS:El resultado principal fue la identificación de la incidencia y los factores de riesgo para la presencia de un estoma permanente. En forma secundaria se describieron los resultados de las diferentes técnicas de la formación de un estoma entre los pacientes con resección interesfintérica parcial, subtotal o total.RESULTADOS:Posterior a una media de seguimiento de cuarenta meses (rango de 6 a 107), 26 de 185 pacientes requirieron en forma eventual un estoma permanente, lo que equivale a una incidencia acumulada a cinco años de 17.4 %. Las causas para dejar un estoma permanente fueron morbilidad de la anastomosis (46.2%, 12/26), recurrencia local (19.2%, 5/26), metástasis a distancia (19.2%, 5/26), incontinencia fecal (3.8%, 1/26), mortalidad perioperatoria (3.8%, 1/26), rechazo del paciente (3.8%, 1/26), y malas condiciones generales (3.8%, 1/26). Aunque la incidencia de un estoma permanente fue significativamente diferente entre los grupos de resección interesfintérica (parcial vs subtotal vs total: 8.3% vs 20% vs 25.8%, p = 0.02), no se consideró un factor predictor independiente para la formación de estoma. En el análisis multivariado se demostró que la fuga anatomótica (OR = 5.29; p = 0.001) y la estenosis anastomótica (OR = 5.13; p = 0.002) fueron factores independientes para predecir la necesidad de un estoma permanente.LIMITACIONES:La naturaleza retrospectiva del estudio y la información proveniente de un solo centro.CONCLUSIONES:La incidencia acumulada a cinco años de estoma permantente fue de 17.4%. Se consideran a las complicaciones anastomóticas como factores de riesgo. Los pacientes deberán ser informados de los riesgos y beneficios cuando se considere la posibilidad de efectuar una cirugía preservadora de esfínteres finalmente. Puede ser preferible disminuir la probabilidad de dejar un estoma permanente tratando de minimizar la posibilidad de complicaciones de la anastomosis.

Diverting Ileostomy Duration Is the Main Determinant of Ileostomy-Related Complications after Surgical Treatment of Rectum Cancer. JOURNAL OF ONCOLOGY 2020; 2020:4186857. [PMID: 32322269 PMCID: PMC7166299 DOI: 10.1155/2020/4186857] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Accepted: 03/16/2020] [Indexed: 01/02/2023]
Abstract
Background This study aimed to investigate factors associated with the development of ileostomy complications in rectal cancer patients, including those who received neoadjuvant treatment. Methods This retrospective trial included 133 consecutive patients who underwent surgery for rectal cancer with temporary diverting ileostomy. Patients' demographic characteristics as well as the pre- and postclosure outcomes and complications were analyzed. Results In logistic regression analysis, longer duration of ileostomy emerged as a significant independent predictor of any complication during ileostomy. The respective odds ratios for 3–6 months and >6 months vs. <3 months of ileostomy duration were as follows: OR, 4.5 (95% CI, 1.2–16.7), p=0.023; and OR, 15.2 (95% CI, 3.1–75.2), p=0.001. An additional stepwise model also identified hypertension as a significant predictor. In stepwise logistic regression model, adjuvant chemoradiotherapy emerged as significant independent predictor of “any ileostomy-related complication after ileostomy closure”: OR, 4.5 (2.0–10.2), p < 0.001. Conclusion Duration of ileostomy appears to be the main determinant of ileostomy-related complications. Patients who had received neoadjuvant or adjuvant therapy had longer ileostomy duration, which may be attributed to the concerns of the surgeon or to the complications themselves.

Abstract
Background An inappropriate anastomosis method during laparoscopic anterior rectal resection can increase the risk of anastomotic complications and affect surgical, economic, and oncological outcomes. The aim of this study is to compare the incidence of anastomotic complications and the surgical, economic, and oncological outcomes following single versus double purse-string anastomosis during laparoscopic total mesorectal excision (TME) for low rectal cancer. Methods/design This randomized controlled trial (the SINGLE–DOUBLE study) will randomly assign middle and low rectal adenocarcinoma patients to receive either single or double purse-string anastomosis during laparoscopic low anterior rectal resection. Patients will be eligible for inclusion only if they (1) have adenocarcinoma confirmed by preoperative colonoscopy and biopsy, (2) have a tumor situated less than 12 cm from the anal verge, (3) do not have the anal sphincter involved, and (4) do not have distant metastases. The primary endpoint measure will be the incidence of anastomotic complications (leakage, narrowing, and bleeding). The secondary endpoints will be surgical, economic, and oncological outcomes. A total of 500 patients will be enrolled in the study. Sample size calculation was based on previous reports and our retrospective analysis. Discussion This randomized single-center controlled trial is expected to demonstrate which anastomosis method (single or double purse-string anastomosis) is better for reducing complications and improving prognosis in rectal cancer patients undergoing laparoscopic TME for low or middle rectal cancer.
