Impact of Anastomotic Leakage After Colorectal Cancer Surgery on Quality of Life: A Systematic Review.

Colorectal anastomotic leakage remains one of the most frequent and dreaded postoperative complications following colorectal resection. However, limited research has been conducted on the impact of this complication on quality of life of patients undergoing colorectal cancer surgery. The aim of this systematic review was to identify, appraise and synthesize the available evidence regarding quality of life in patients with anastomotic leakage following oncological colorectal resections in order to inform clinical decision-making. PubMed, Embase, and the Cochrane library were searched for studies reporting on quality of life using validated questionnaires in patients with anastomotic leakage after oncological colorectal resections. The literature search was performed systematically and according to PRISMA guidelines. Outcomes of quality of life questionnaire scores of patients with and without anastomotic leakage were analyzed. Thirteen articles reporting on 4618 individual patients were included, among which 527 patients developed anastomotic leakage. Quality of life was evaluated utilizing ten distinct questionnaires administered at various postoperative time points, ranging from 1 month to 14 years. Quality of life outcomes differed across studies and timepoints, but overall scores were most negatively affected by anastomotic leakage up to 12 months postoperatively. There was a high heterogeneity between the included studies based on used questionnaires and time of assessment. The published evidence suggests that anastomotic leakage following oncologic colorectal resection is associated with impaired quality of life, especially within the first postoperative year. The impact of anastomotic leakage on quality of life warrants further evaluation and discussion with patients.

LABORATORY PREDICTORS FOR DIAGNOSING COLORECTAL ANASTOMOTIC LEAKAGE.

An important concern in oncological coloproctology is colorectal anastomotic leakage (AL), which occurs in 3.5%-21% of patients. Predicting the occurrence of failure based on the results of laboratory markers can be decisive for the treatment of this complication. To improve the early diagnosis of AL by establishing combinations and threshold values of laboratory markers - predictors of the inflammatory process. The prospective study, conducted from 2020 to 2023, included 213 rectal cancer patients who underwent low anterior resection after neoadjuvant chemoradiotherapy. The inflammatory biomarkers were assessed before surgery and on the 3rd, 5th, and 7th days of the postoperative period. AL diagnosed in 25 (11.74%) patients by the grade of severity was as follows: A (radiological) in 7 (3.29%) patients; B (clinical) - 4 (1.88%); C (clinically expressed, peritonitis) - 11 (5.16%), and P (late) - 3 (1.41%) patients. The changes in the laboratory indicators of the inflammatory response such as С-reactive protein (CRP), procalcitonin (PCT), the counts of neutrophils (NEU), lymphocytes (LYM), platelets (PLT), and neutrophil/lymphocyte ratio (NLR) were significant only in B or C AL grades. Among them, only three indicators were identified as significant for predicting AL when assessed 24 h before the onset of this complication, namely LYM (threshold value ≤ 0.97 × 103/mm3, sensitivity 66.7% and specificity 81.3%, p < 0.001); PLT (threshold value > > 257 103/mm3, sensitivity 58.6%, and specificity 86.7%, p < 0.001); and NLR (threshold value > 4.42, sensitivity 58.1%, and specificity 86.7%, p < 0.001). The three-factor model based on these selected indicators was set up, and the prognosis index (Prog) was proposed with the decision threshold Progcrit = 2.23. The sensitivity of the model was 80% (95% CI 51.9%-95.7%), and the specificity - 74.2% (67.6%-80.2%). Based on the routine laboratory predictors used in the complex diagnosis of AL, B or C AL grades may be predicted allowing for the timely effective early diagnosis, medication, and surgical intervention..

Procalcitonin as an Early Marker of Colorectal Anastomotic Leakage in Postoperative Colorectal Cancer Patients: A Systematic Review and Meta-Analysis.

Background The timely identification of colorectal anastomotic leakage (CAL)is still a significant challenge, and identifying reliable markers is essential to minimize patient morbidity and mortality. While procalcitonin (PCT) has shown promise as a biomarker for CAL, its effectiveness must be specifically evaluated in colorectal cancer patients. This systematic review and meta-analysis sought to assess the mean differences in PCT levels between individuals with and without CAL who underwent colorectal surgery for colorectal cancer. Methodology A comprehensive search of the "PubMed,""Scopus," and "Web of Science" databases was carried out, covering studies published through April 2024. The objective was to identify studies examining PCT levels in colorectal cancer patients who underwent colorectal surgery, with a particular focus on the occurrence of CAL. Data on the meanof PCT levels in CAL and non-CAL patients were extracted from the selected studies. The mean differences in PCT levels were subsequently analyzed for each postoperative day (POD). Results Seventeen articles were selected for inclusion in this systematic review. The statistical analysis included five eligible articles that assessed PCT levels in groups exclusively involving patients with colorectal cancer. The findings showed no significant increase in PCT levels in CAL patients compared to non-CAL patients on any POD when a leave-one-out sensitivity analysis was performed to validate the results. Conclusions To date, PCT levels should not be regarded as early indicators of CAL after colorectal surgery in patients with colorectal cancer. Additional research is necessary to evaluate if PCT could be a dependable marker for CAL in this particular setting.

Factors Limiting Ostomy Reversal After Cytoreductive Surgery for Ovarian Cancer: A Retrospective Study.

To investigate the factors related to non-reversal of ostomy after cytoreductive surgery in ovarian cancer. In many women with ovarian cancer, transitory ostomies are performed to limit the consequences of anastomotic leak. Although intended to be temporary, a proportion of these ostomies might never be reversed. This was a retrospective study of patients with 2014 International Federation of Obstetrics and Gynecology stage IIB-IVB ovarian cancer requiring a transitory ostomy during primary or secondary cytoreductive surgery at the Bergonie Institute, France, and the University Hospital of Las Palmas, Spain, between January 2012 and December 2022. Rate of ostomy reversal, its timing (weeks) and postoperative complications were assessed. Multivariate logistic regression analysis was performed to identify limiting factors for ostomy reversal. During the study period, we reviewed data on 181 consecutive patients with ovarian cancer with transitory ostomy creation; 89 (49.2%) patients were not candidates for an ostomy reversal surgery because of disease progression (n=65), death (n=16), and patient's refusal of surgery (n=8). A total of 92 patients were candidates for reversal surgery and were therefore included in the final analysis. In total, 57 (62%) patients had their ostomy reversed. The mean time from ostomy creation to ostomy closure was 47.7 (standard deviation=33.1) weeks. Hartmann's procedure (leaving a rectal stump of 5-6 cm) was identified as an independent predictive factor for non-reversal of ostomy (odds ratio=6.42, 95% confidence interval=1.61-25.53; p=0.008). Complications after ostomy reversal occurred in 32 patients (34.8%). Hartmann's procedure is a limiting factor for ostomy reversal in patients with ovarian cancer. We recommend avoiding Hartmann's procedure during cytoreductive surgery, even after colorectal anastomotic leak.

Quality of Reporting on Anastomotic Leaks in Colorectal Cancer Trials: A Systematic Review.

Although attempts have been made in the past to establish consensus regarding the definitions and grading of the severity of colorectal anastomotic leakage, widespread adoption has remained limited. A systematic review of the literature was conducted with the objective of examining the various elements used to report and define anastomotic leakage in colorectal cancer resections. A systematic review, using the PubMed, Embase, and Cochrane Library Database, of all published randomized controlled trials, systematic reviews, and meta-analyses containing data related to adult patients undergoing colorectal cancer surgery and reporting anastomotic leakage as a primary or secondary outcome, with a definition of anastomotic leakage included. Definitions of anatomotic leakage, clinical symptoms, radiological modalities and findings, findings at reoperation, as well as grading terminology or classifications for anastomotic leakage. Of the 471 articles reporting anastomotic leakage as a primary or secondary outcome, a definition was reported in 95 studies (45 randomized controlled trials, 13 systematic reviews, and 37 meta-analyses), involving a total of 346,140 patients. Of these 95 articles, 68% reported clinical signs and symptoms of anastomotic leakage, 26% biochemical criteria, 63% radiological modalities, 62% radiological findings, and 13% findings at reintervention. Only 45% (n = 43) of included studies reported grading of anastomotic leakage severity or leak classification, and 41% (n = 39) included a timeframe for reporting. There was a high heterogeneity between the included studies. This evidence synthesis confirmed incomplete and inconsistent reporting of anastomotic leakage across the published colorectal cancer literature. There is a great need for the development and implementation of a consensus framework for defining, grading, and reporting anastomotic leakage. Prospectively registered at PROSPERO ID 454660.

Risk Factor Targeted Perioperative Care Reduces Anastomotic Leakage after Colorectal Surgery: The DoubleCheck study.

The DoubleCheck study aimed to introduce pre- and perioperative interventions minimizing exposure to modifiable risk factors and determine its effect on CAL. Colorectal anastomotic leakage (CAL) is a severe complication. In order to predict and prevent its occurrence, the LekCheck study identified intraoperative modifiable risk factors for CAL: anemia, hyperglycemia, hypothermia, incorrect timing of antibiotic prophylaxis, administration of vasopressors and epidural analgesia. This international open-labelled interventional study was performed between September 2021 and December 2023. An enhanced care bundle consisting of anemia correction, glucose measurement, attaining normothermia, antibiotics administration within 60 to 15 minutes preoperatively, refraining from vasopressors and epidural analgesia was introduced. Primary outcome was the occurrence of intraoperative risk factors just prior to the anastomosis creation. Secondary outcomes were CAL and mortality. Univariate and multivariate regression analysis were performed to establish the relationship between the enhanced care bundle, exposure to the six factors and CAL. The historical LekCheck group consisted of 1572 patients versus 902 in the DoubleCheck. The LekCheck group had a mean of 1.84 risk factors versus 1.63 in DoubleCheck ( P <0.001). In the DoubleCheck significantly less patients had ≥3 risk factors ( P <0.001). CAL was significantly lower in the DoubleCheck group (8.6% vs. 6.2%, P =0.039). The reduction of CAL was associated with the enhanced care bundle in multivariate regression analysis (OR 1.521, 95% CI 1.01-2.29, P =0.045). The mortality rate did not differ significantly (1.3%, vs. 0.8%, P =0.237). The DoubleCheck study showed that optimization of modifiable risk factors reduced CAL in colorectal surgery.

The impact of anastomotic leakage on the quality of life of patients after surgery for rectal cancer

AIM: to assess the impact of colorectal anastomotic leakage on the severity of low anterior rectal resection syndrome and the quality of life.PATIENTS AND METHODS: the results of 375 patients with rectal tumors were analyzed. In 26 patients, surgery was complicated by anastomosis failure. For a assessment of the quality of life of patients with anastomotic leakage, each patient was matched with a pair from the group of respondents with an uncomplicated postoperative period. The quality of life was assessed in all patients using the EORTC QLQ-C30 questionnaire with the Cr-29 module.RESULTS: patients with anastomosis leakage have more severe low anterior rectal resection syndrome — 29 (17;34), versus 20 (9;28) points (p = 0.03) and a lower global score (p = 0.01), physical (p = 0.01) and social (p = 0.04) functioning. The symptom scales of the EORTC QLQ-C30 questionnaire, supplemented by the Cr-29 module, had significant differences between groups on the scales of body image (p = 0.01), fecal incontinence (p = 0.04) and embarrassment (p = 0.01).CONCLUSION: colorectal anastomosis leakage negatively affects the quality of life of patients.

Procalcitonin and C-reactive protein as early predictors in patients at high risk of colorectal anastomotic leakage.

To assess the diagnostic value of C-reactive protein (CRP) and procalcitonin (PCT) for anastomotic leakage (AL) following colorectal surgery. We retrospectively analyzed data for patients who underwent colorectal surgery at our hospital between November 2019 and December 2023. CRP and PCT were measured postoperatively to compare patients with/without AL, and changes were compared between low- and high-risk groups. Receiver operating characteristic (ROC) curve analysis was used to assess the diagnostic accuracy of CRP and PCT to identify AL in high-risk patients. Mean CRP was 142.53 mg/L and 189.57 mg/L in the low- and high-risk groups, respectively, on postoperative day (POD)3. On POD2, mean PCT was 2.75 ng/mL and 8.16 ng/mL in low- and high-risk patients, respectively; values on POD3 were 3.53 ng/mL and 14.86 ng/mL, respectively. The areas under the curve (AUC) for CRP and PCT on POD3 were 0.71 and 0.78, respectively (CRP cut-off: 235.64 mg/L; sensitivity: 96%; specificity: 89.42% vs PCT cut-off: 3.94 ng/mL; sensitivity: 86%; specificity: 93.56%; AUC: 0.78). The AUC, sensitivity, and specificity for the combined diagnostic ability of CRP and PCT on POD3 were 0.92, 90%, and 100%, respectively (cut-off: 0.44). Combining PCT and CRP on POD3 enhances the diagnostic accuracy for AL.

Enhanced perioperative care for the prevention of anastomotic leakage – DOUBLE CHECK: study protocol for an international, multicenter open-label trial with historical controls

Background: Colorectal anastomotic leakage (CAL) remains a severe complication after bowel surgery. Recent research has identified several modifiable perioperative CAL risk factors. The aim of this study is to implement an enhanced perioperative care protocol, to optimize the intraoperative condition of the patient and minimalize exposure to modifiable CAL risk factors. Secondly, this study will investigate whether implementation of this new protocol results in a decreased CAL rate. Methods: The DOUBLE CHECK study will be performed using an open-label, international, multicenter design in 11 participating hospitals. The aim is to include an intervention group of 943 adult patients that underwent a colorectal resection with creation of a primary anastomosis. The patients in the intervention group will be treated according to an enhanced perioperative care protocol focusing on optimizing the intraoperative condition of the patient by minimalizing exposure to the following perioperative factors: anemia, hyperglycemia, hypothermia, epidural anesthesia, vasopressor drug administration, and incorrect or lack of antibiotic prophylaxis. The control group will consist of 1562 historical patients that were treated with standard perioperative practice (LekCheck study cohort). The patient’s intraoperative condition defined by exposure to the six perioperative risk factors, compliance to the DOUBLE CHECK study protocol, 30-day and 90-day CAL and other postoperative complications, length of hospital-stay, and ICU stay, hospital readmission and 30-day mortality will be measured. Discussion: The strength of this study is that it is an implementation study of an enhanced perioperative practice protocol for patients that are scheduled for colorectal resection in combination with a comparative study. This protocol could be a tool for other hospitals that want to improve their perioperative care pathway.

Colorectal anastomotic leakage: a narrative review of definitions, grading systems, and consequences of leaks.

Anastomotic leaks (ALs) are a significant and feared postoperative complication, with incidence of up to 30% despite advances in surgical techniques. With implications such as additional interventions, prolonged hospital stays, and hospital readmission, ALs have important impacts at the level of individual patients and healthcare providers, as well as healthcare systems as a whole. Challenges in developing unified definitions and grading systems for leaks have proved problematic, despite acknowledgement that colorectal AL is a critical issue in intestinal surgery with serious consequences. The aim of this study was to construct a narrative review of literature surrounding definitions and grading systems for ALs, and consequences of this postoperative complication. A literature review was conducted by examining databases including PubMed, Web of Science, OVID Embase, Google Scholar, and Cochrane library databases. Searches were performed with the following keywords: anastomosis, anastomotic leak, colorectal, surgery, grading system, complications, risk factors, and consequences. Publications that were retrieved underwent further assessment to ensure other relevant publications were identified and included. A universally accepted definition and grading system for ALs continues to be lacking, leading to variability in reported incidence in the literature. Additional factors add to variability in estimates, including differences in the anastomotic site and institutional/individual differences in operative technique. Various groups have worked to publish guidelines for defining and grading AL, with the International Study Group of Rectal Cancer (ISGRC/ISREC) definition the current most recommended universal definition for colorectal AL. The burden of AL on patients, healthcare providers, and hospitals is well documented in evidence from leak consequences, such as increased morbidity and mortality, higher reoperation rates, and increased readmission rates, among others. Colorectal AL remains a significant challenge in intestinal surgery, despite medical advancements. Understanding the progress made in defining and grading leaks, as well as the range of negative outcomes that arise from AL, is crucial in improving patient care, reduce surgical mortality, and drive further advancements in earlier detection and treatment of AL.

Clinical Utility of Laser Speckle Contrast Imaging and Real-Time Quantification of Bowel Perfusion in Minimally Invasive Left-Sided Colorectal Resections.

Left-sided colorectal surgery demonstrates high anastomotic leak rates, with tissue ischemia thought to influence outcomes. Indocyanine green is commonly used for perfusion assessment, but evidence remains mixed for whether it reduces colorectal anastomotic leaks. Laser speckle contrast imaging provides dye-free perfusion assessment in real-time through perfusion heat maps and quantification. This study investigates the efficacy of advanced visualization (indocyanine green versus laser speckle contrast imaging), perfusion assessment, and utility of laser speckle perfusion quantification in determining ischemic margins. Prospective intervention group using advanced visualization with case-matched, retrospective control group. Single academic medical center. Forty adult patients undergoing elective, minimally invasive, left-sided colorectal surgery. Intraoperative perfusion assessment using white light imaging and advanced visualization at 3 time points: T1-proximal colon after devascularization, before transection, T2-proximal/distal colon before anastomosis, and T3-completed anastomosis. Intraoperative indication of ischemic line of demarcation before resection under each visualization method, surgical decision change using advanced visualization, post hoc laser speckle perfusion quantification of colorectal tissue, and 30-day postoperative outcomes. Advanced visualization changed surgical decision-making in 17.5% of cases. For cases in which surgeons changed a decision, the average discordance between the line of demarcation in white light imaging and advanced visualization was 3.7 cm, compared to 0.41 cm ( p = 0.01) for cases without decision changes. There was no statistical difference between the line of ischemic demarcation using laser speckle versus indocyanine green ( p = 0.16). Laser speckle quantified lower perfusion values for tissues beyond the line of ischemic demarcation while suggesting an additional 1 cm of perfused tissue beyond this line. One (2.5%) anastomotic leak occurred in the intervention group. This study was not powered to detect differences in anastomotic leak rates. Advanced visualization using laser speckle and indocyanine green provides valuable perfusion information that impacts surgical decision-making in minimally invasive left-sided colorectal surgeries. See Video Abstract . ANTECEDENTES:La cirugía colorrectal del lado izquierdo demuestra altas tasas de fuga anastomótica, y se cree que la isquemia tisular influye en los resultados. El verde de indocianina se utiliza habitualmente para evaluar la perfusión, pero la evidencia sobre si reduce las fugas anastomóticas colorrectales sigue siendo contradictoria. Las imágenes de contraste moteado con láser proporcionan una evaluación de la perfusión sin colorantes en tiempo real a través de mapas de calor de perfusión y cuantificación.OBJETIVO:Este estudio investiga la eficacia de la evaluación de la perfusión mediante visualización avanzada (verde de indocianina versus imágenes de contraste moteado con láser) y la utilidad de la cuantificación de la perfusión con moteado láser para determinar los márgenes isquémicos.DISEÑO:Grupo de intervención prospectivo que utiliza visualización avanzada con un grupo de control retrospectivo de casos emparejados.LUGARES:Centro médico académico único.PACIENTES:Cuarenta pacientes adultos sometidos a cirugía colorrectal electiva, mínimamente invasiva, del lado izquierdo.INTERVENCIONES:Evaluación de la perfusión intraoperatoria mediante imágenes con luz blanca y visualización avanzada en tres puntos temporales: T1-colon proximal después de la devascularización, antes de la transección; T2-colon proximal/distal antes de la anastomosis; y T3-anastomosis completa.PRINCIPALES MEDIDAS DE VALORACIÓN:Indicación intraoperatoria de la línea de demarcación isquémica antes de la resección bajo cada método de visualización, cambio de decisión quirúrgica mediante visualización avanzada, cuantificación post-hoc de la perfusión con láser moteado del tejido colorrectal y resultados posoperatorios a los 30 días.RESULTADOS:La visualización avanzada cambió la toma de decisiones quirúrgicas en el 17,5% de los casos. Para los casos en los que los cirujanos cambiaron una decisión, la discordancia promedio entre la línea de demarcación en las imágenes con luz blanca y la visualización avanzada fue de 3,7 cm, en comparación con 0,41 cm (p = 0,01) para los casos sin cambios de decisión. No hubo diferencias estadísticas entre la línea de demarcación isquémica utilizando láser moteado versus verde de indocianina (p = 0,16). El moteado con láser cuantificó valores de perfusión más bajos para los tejidos más allá de la línea de demarcación isquémica y al mismo tiempo sugirió 1 cm adicional de tejido perfundido más allá de esta línea. Se produjo una fuga anastomótica (2,5%) en el grupo de intervención.LIMITACIONES:Este estudio no tuvo el poder estadístico suficiente para detectar diferencias en las tasas de fuga anastomótica.CONCLUSIONES:La visualización avanzada utilizando moteado láser y verde de indocianina proporciona información valiosa sobre la perfusión que impacta la toma de decisiones quirúrgicas en cirugías colorrectales mínimamente invasivas del lado izquierdo.

Unveiling a rare adverse event: sponge migration during endoscopic vacuum therapy for colorectal anastomotic leak

Unveiling a rare adverse event: sponge migration during endoscopic vacuum therapy for colorectal anastomotic leak

Successful Clinical Avoidance of Colorectal Anastomotic Leakage through Local Decontamination.

An anastomotic leak is an unpredictable postoperative complication during recovery from colorectal surgery that may require a re-operation. Potentially pathogenic bacteria like Pseudomonas (and Enterococcus) contribute to the pathogenesis of an anastomotic leak through their capacity to degrade collagen and to activate tissue matrix metalloprotease-9 in host intestinal tissues. The microbiome, therefore, is the key to preventing an anastomotic leak after colorectal surgery. The aim of this trial was to investigate whether perioperative selective decontamination with a new mixture of locally acting antibiotics specially designed against Pseudomonas aeruginosa and Enterococcus faecalis can reduce or even stop early symptomatic leakage. All hospitalized patients in our University Clinic undergoing colorectal surgery with a left-sided anastomosis were included as two groups; patients in the intervention group received polymyxin B, gentamicin and vancomycin every six hours for five postoperative days and those in the control group did not receive such an intervention. An anastomotic leak was defined as a clinically obvious defect of the intestinal wall integrity at the colorectal anastomosis site (including suture) that leads to a communication between the intra- and extraluminal compartments, requiring a re-do surgery within seven postoperative days. Between February 2017 and May 2023, a total of 301 patients (median age of 63 years) were analyzed. An anastomotic leak was observed in 11 patients in the control group (n = 152), but in no patients in the intervention group (n = 149); this difference was highly significant. The antibiotic mixture (with polymyxin B, gentamicin and vancomycin) used for local decontamination in our study stopped the occurrence of anastomotic leaks completely. According to the definition of anastomotic leak, no further surgery was required after local perioperative decontamination.

Influence of colorectal anastomotic leakage on time before the loop stoma closing

Background. Important task is determining the long-term consequences of colorectal anastomotic leakage. Leakage with clinical manifestations leads to a higher frequency of local recurrences of rectal cancer and increases the severity of manifestations of low anterior resection syndrome. How does the leakage of colorectal anastomosis affect the period before the closure of loop stoma?Aim. To determine the influence of anastomotic leakage on the term before closing the ileostomy.Methods. In this retrospective incomparable study were included 618 patients with rectal cancer who had been underwent anterior or low anterior resection with formation colorectal anastomosis and loop stoma.Results. Colorectal anastomotic leakage was detected in 86 from 618 patients (13.9 %). The loop stoma was closed in 513 from 618 (83 %) patients. The time to the preventive stoma closure in patients with anastomotic leakage was significantly higher than in patients without anastomotic leakage, p = 0.001. Reconstructive surgery in patients without anastomotic leakage was performed in 9 months after anterior resection. The median time before the stoma closure of patients with X – ray anastomosis leakage was 11 months, with clinical leakage – 17 months, p &lt;0.001.Conclusion. Colorectal anastomotic leakage statistically increases the term before ileostomy closure.

Is early CT in cases of elevated postoperative CRP the best option for the diagnosis of colorectal anastomotic leakage?

After colorectal surgery (CRS), the early detection and treatment of anastomotic leakage (AL) is critical. We aimed to evaluate the efficacy of early contrast-enhanced computed tomography (CT) (postoperative day [POD] 2-3) after elective colorectal surgery for the diagnosis of AL for patients with elevated CRP levels at POD 2-3. From 2017 to 2022, all patients who underwent elective CRS with an anastomosis and CRP > 150mg/ml on POD 2-3 underwent enhanced CT during the 24h following the CRP evaluation and were included in this retrospective, single-center study. The primary endpoint was the diagnostic value of the early CT scan for the detection of AL. The secondary endpoints were the diagnostic value of the early CT scan for the detection of grade C AL according to the type of resection and anastomosis and the quality of the opacification. A total of 661 patients underwent elective CRS with anastomosis with an overall AL rate of 7.4%. Among the 661 patients, 141 were finally included in the study. The accuracy of early CT for the diagnosis of AL was 83.7%. For grade C AL, the accuracy was 81.6%. Among patients who had an ileocolic anastomosis, the accuracy was 88.2%, among those who had colorectal or ileorectal anastomosis, the accuracy was 83.0%, and among those who had a coloanal, the accuracy was 66.7%. In cases of good opacification by CT, the accuracy was 84.0%. Early CT does not show perfect accuracy for an early diagnosis of AL.

Peritoneal and Systemic Interleukin-10 as Early Biomarkers for Colorectal Anastomotic Leakage Following Surgery in Colorectal Cancer Patients: A Systematic Review and Meta-Analysis.

&lt;b&gt;&lt;br&gt;Introduction:&lt;/b&gt; Despite advancements in diagnostic methods, the early detection of colorectal anastomotic leakage (CAL) continues to pose challenges. The identification of reliable markers is crucial to reduce patient morbidity and mortality. Cytokines present in drain fluid and systemic cytokine levels have shown promise as predictive markers for CAL; however, additional high-quality evidence is warranted to enhance the reliability and validity of the findings in this field.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Aim:&lt;/b&gt; This systematic review and meta-analysis aimed to assess the significance of peritoneal and serum/plasma interleukin-10 (IL-10) levels in the early detection of CAL in patients undergoing colorectal surgery for colorectal cancer.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Methods:&lt;/b&gt; A comprehensive literature search was conducted in PubMed, Scopus, and Web of Science databases, covering studies published until July 2023. The search aimed to identify relevant studies investigating the levels of plasma/serum and peritoneal IL-10 (or both) in colorectal cancer patients undergoing colorectal surgery, specifically focusing on the presence of CAL. Data on the mean and standard deviation of IL-10 levels in both CAL and non-CAL patients were extracted from the selected studies. Mean differences in IL-10 levels were analyzed for each postoperative day (POD) using the OpenMeta [analyst] software.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Results:&lt;/b&gt; 11 articles were selected for inclusion in this systematic review. Among them, nine articles reported data on peritoneal IL-10 levels, while four articles focused on circulating IL-10 levels. The statistical analysis included four eligible articles that assessed peritoneal IL-10 levels, and the results indicated no significant increase in CAL patients compared to non-CAL patients on any postoperative day (POD). Meta-analysis for circulating IL-10 levels was not feasible.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Conclusions:&lt;/b&gt; Up to now, peritoneal and systemic IL-10 levels cannot be considered as early markers for CAL after colorectal surgery in colorectal cancer patients. More high-quality studies are needed to establish the potential of IL-10 as a reliable marker for detecting anastomotic leakage after colorectal surgery.&lt;/br&gt.

The failed colorectal anastomosis: Turnbull–Cutait as a salvage option

The incidence of colorectal anastomotic leaks is approximately 5–19 % of cases, posing a threat to intestinal continuity, particularly if the leak arises after a low or ultra-low colorectal anastomosis. A Turnbull–Cutait procedure can be a salvage option for such patients and they may be eligible if they are adequate redo pelvic surgery candidates, who are motivated to regain intestinal continuity, and who have good continence and anal function at baseline. The first stage of the procedure is colonic mobilization and pull-through after perineal division at the top of the anorectal complex and mucosectomy. A diverting loop ileostomy is utilized. The second stage is amputation of the excess colon and creation of a hand-sewn colo-anal anastomosis, typically performed 7 days later. Outcomes after a Turnbull–Cutait procedure are reasonable based on a series from specialized centers with 80–90 % of patients having a complete Turnbull–Cutait and reversal of the diverting ileostomy. Low anterior resection syndrome is common. In the long-term, studies show that just over half of patients will remain stoma free at 5 years; fecal incontinence is the main reason for failure and return to a stoma. The prospect of a Turnbull–Cutait can be kept in mind when addressing an anastomotic leak in appropriate patients; this may allow for surgical decision-making that makes it feasible to utilize a Turnbull–Cutait in the future.
