Background: Systemic inflammatory markers have emerged as accessible and reproducible tools for oncologic risk stratification, yet their prognostic value in rectal cancer remains incompletely defined, particularly in acute surgical settings. This study aimed to assess six inflammation-based indices—NLR, PLR, MLR, SII, SIRI, and AISI—in relation to tumor stage, recurrence, and outcomes among patients undergoing emergency versus elective resection for rectal cancer. Methods: We retrospectively evaluated 174 patients treated between 2018 and 2024. Pre-treatment blood counts were used to calculate inflammatory indices. Clinical and pathological parameters were correlated with biomarker levels using univariate and multivariate analyses. Results: Pre-treatment inflammation markers were significantly elevated in patients requiring emergency surgery (e.g., NLR: 3.34 vs. 2.4, p = 0.001; PLR: 204.1 vs. 137.8, p < 0.001; SII: 1008 vs. 693, p = 0.007), reflecting advanced tumor biology and immune activation. Notably, these patients also had higher rates of stage IV disease (p = 0.029) and permanent stoma (p = 0.002). Post-treatment, recurrence was paradoxically associated with significantly lower levels of SII (p = 0.021), AISI (p = 0.036), and PLR (p = 0.003), suggesting a potential role for immune exhaustion rather than hyperinflammation in early relapse. Conclusions: Inflammatory indices provide valuable insights into both tumor local invasion and host immune status in rectal cancer. Their integration into perioperative assessment could improve prognostication, particularly in emergency presentations. Post-treatment suppression of these markers may identify patients at high risk for recurrence despite initial curative intent. Full article

Background/Objectives: This study aimed to assess the frequency, risk factors, and clinical implications of cytomegalovirus (CMV) colitis in patients undergoing colectomy due to refractory ulcerative colitis (UC). Methods: A retrospective analysis was conducted on patients with drug-resistant UC who underwent colectomy at a tertiary referral center between 2009 and 2017. Histological inflammatory activity in surgical specimens was assessed using the Simplified Geboes Score. The presence and density of CMV expression were estimated immunohistochemically. Preoperative clinical, biochemical, and endoscopic data, as well as the short- and long-term postoperative disease courses, were evaluated in relation to the presence of CMV colitis at the time of surgery. Results: CMV colitis was identified in 14% (7/49) of patients. The CMV-positive group exhibited significantly shorter disease durations and higher C-reactive protein concentrations at the time of surgery. This subgroup also demonstrated consistently numerically higher steroid use, both in terms of the usage frequency and cumulative treatment duration. Patients with concomitant CMV colitis had lower likelihoods of stoma closure and restoration of gastrointestinal continuity in the long-term. Conclusions: Concomitant CMV colitis is not uncommon in patients with treatment-refractory UC. Testing for CMV should be considered, particularly in individuals with a short-term, dynamic, and aggressive disease course unresponsive to standard therapy, especially steroids. Full article

Background/Objective: Immune checkpoint inhibitors (ICIs) are highly effective cancer therapies used across a broad spectrum of malignancies. They function by disrupting immune inhibitory pathways, resulting in an amplified immune response against tumors. However, this heightened immune activity can predispose patients to immune-mediated colitis (IMC), which is graded using the Common Terminology Criteria for Adverse Events (CTCAE) and can range from mild diarrhea to severe colitis. Prior studies have shown that fecal stream diversion can modify the gut microbiome and influence the severity of intestinal inflammation. This study investigates the impact of fecal stream diversion on IMC outcomes in cancer patients receiving ICIs. Methods: We conducted a retrospective cohort study of patients treated with ICIs from 2016 to 2023 who had a history of fecal stream diversion. Demographic, oncologic, and toxicity-related data were collected. Patients with active gastrointestinal infections, autoimmune GI diseases, or graft-versus-host disease were excluded. Descriptive statistics and univariate and multivariate logistic regression analyses were performed using SAS version 9.4. Results: A total of 44 patients were included and categorized into two groups based on the timing of bowel stoma creation relative to the IMC event. CTCAE grade for diarrhea was used to assess GI toxicity. While overall CTCAE grade distribution for diarrhea did not differ significantly between groups (p = 0.22), Hispanic ethnicity was significantly associated with a lower CTCAE grade compared to non-Hispanic or Latino individuals (OR [95% CI] = 0.12 [0.02, 0.62], p = 0.011). In contrast, higher CTCAE grades were significantly associated with ileostomy versus colostomy (OR [95% CI] = 3.21 [1.01, 10.18], p = 0.048) and in patients without an ostomy at the time of diarrhea onset compared to those with an ostomy (OR [95% CI] = 8.87 [2.51, 31.31], p = 0.0007). Conclusions: Our findings suggest that the CTCAE diarrhea grade is significantly associated with ethnicity, type of stoma, and presence of ostomy at the time of diarrhea. Limitations include the retrospective study design and small sample size. These results contribute to understanding potential strategies for mitigating the serious gastrointestinal toxicities of ICIs. Full article

Background: The guidelines proposed by the World Society for Emergency Surgery (WSES) in 2020 for the management of Acute Diverticulitis (AD) emphasize the safety of non-operative management (NOM) in selected patients and recommend sigmoid resection (SR) with primary anastomosis (PA) as the surgical technique of choice. Aim: To analyze the clinical outcomes following the implementation of an evidence-based clinical pathway developed by an Acute Care Surgery Unit (ACSu) at a reference center. Methods: For analysis, patients were divided into two groups: pre-guidelines (2018–2019) and post-guidelines (2020–2023), following the May 2020 WSES publication. Patients were classified according to the WSES classification. Results: NOM failure and PA after SR rates by groups were as follows (NOM failure not applicable to III–IV): 0-IA, 2.7% and 94.7%; IB–IIA, 16% and 85.2%; IIB, 7.1% and 50%; III–IV, 75.6%. The global stoma-free rate was 78.8%, with a 15.7% anastomotic leak rate and 14.2% significant morbidity, with an increased rate of anastomosis in unstable patients thanks to Damage Control Surgery (DCS). A logistic regression model was performed to identify factors associated with postoperative morbidity. Patients who underwent primary anastomosis had a lower risk of postoperative morbidity compared to those treated with Hartmann’s procedure (OR = 0.22 (0.04–1.25), p = 0.088). Conclusions: Excellent outcomes in AD healthcare may be achieved if evidence-based recommendations are followed. The ACSu plays a key role in designing and promoting these protocols. Full article

Background/Objectives: Continuous epidural analgesia (CEA) is commonly used to manage postoperative pain in young infants. However, it can impair bladder function, leading to postoperative urinary retention (POUR) and necessitating Foley catheter placement, which carries a risk of urinary tract infection (UTI). Limited research exists on the frequency of POUR and UTIs and factors influencing optimal Foley catheter management in this population. Methods: A retrospective chart analysis conducted at UPMC Children’s Hospital of Pittsburgh included 103 infants who had surgery with CEA. The patients were assigned to Group A (Foley catheter removed before epidural discontinuation), Group B (Foley catheter removed after epidural discontinuation), and Group C (no Foley catheter placement). Data collected included demographics, details regarding urinary complications, epidural analgesia, pain management, and Foley catheter management. Results: The median/IQR age was 8 weeks (0.71–13.29), and the weight was 3.01 (2.55–3.52) kg. POURs occurred shortly after surgery in two (1.9%) infants with no initial Foley catheter placement (p = 0.101). Two (1.9%) infants in Group B developed a UTI (p = 0.327). A total of 10 (9.7%) (Groups A and B) had a preexisting urologic condition (p = 0.040). Common surgeries included exploratory laparotomy with bowel resection (34%) and stoma closure (28.2%). The epidural catheter was discontinued on postoperative day 3 (median) (p = 0.587). Total opioid administration, median/IQR (MME mg/kg), was significantly higher in Group B (1.7/0.6–3.8) and Group A (0.7/0.3–1.8) compared to Group C (0.6/0.3–1.1) (p = 0.029). Conclusions: No POUR occurred when the Foley catheter was removed before the epidural was discontinued. UTIs occurred when the Foley catheter remained after epidural discontinuation. Our findings highlight the importance of individualized assessment for urinary catheter placement and early removal in young infants receiving CEA. Full article

Background and Objectives: Rectal cancer is a major cause of morbidity and mortality worldwide, and although current therapeutic protocols have improved survival, treatment-related toxicities may significantly affect patients’ daily functioning and emotional well-being. This study aimed to prospectively assess the impact of radiotherapy with concurrent capecitabine on functional and symptomatic outcomes in patients with rectal cancer, with a particular focus on the presence of a stoma and treatment strategy. Materials and Methods: From 165 patients initially assessed, 64 were included in this study after applying eligibility criteria. All received pelvic radiotherapy (50.4 Gy in 28 fractions); 62.5% also received CAPOX chemotherapy. The quality of life was assessed using EORTC QLQ-C30 and QLQ-CR29 questionnaires administered at three time points: before treatment, mid-treatment (day 15), and post-treatment. Results: A statistically significant deterioration was observed in physical, emotional, social, and role functioning over the course of treatment, along with an increase in symptom scores for fatigue, pain, gastrointestinal, and urinary complaints. The presence of a stoma was significantly associated with worse gastrointestinal symptoms and emotional functioning. No significant differences were noted between patients with or without chemotherapy. Despite symptom worsening, global quality-of-life scores remained relatively stable. Conclusions: These findings highlight the complex interplay between treatment toxicity and patient adaptation. The presence of a stoma and other clinical or demographic factors significantly influence patients’ experience during therapy. Integrating routine assessment of functional and symptomatic burden into clinical practice could support individualized interventions aimed at maintaining daily functioning and psychological resilience during treatment.

Background/Objectives: Ostomy creation surgery is a common intervention for patients with conditions such as colorectal cancer, ulcerative colitis, Crohn’s disease, or acute events like trauma and gastrointestinal perforation. Individuals with an ileostomy face unique challenges when managing their new ostomies due to the liquid caustic nature of the effluent, increasing the likelihood of leakage and peristomal skin complications (PSCs). This sub-analysis evaluates the prevalence of leakage and PSCs in a cohort of individuals with a new ileostomy and examines the risk of leakage of different ostomy pouching systems and their impact on leakage and PSCs. Methods: This sub-analysis examined a cohort of 98 patients from a previously published retrospective chart review of stoma-creation surgeries at the University of Pittsburgh Medical Center. Data on pouching system selection, leakage, and PSCs were collected from electronic medical records and evaluated across 479 pouch changes. Two main barrier pouching systems were analyzed: elastic tapeless border (ETB) and ceramide-infused tape-border (CIB) barriers. Statistical analyses using generalized linear mixed models assessed the risk of leakage for each barrier type and controlled for significant differences in the sub-groups. Results: The prevalence of leakage in the ileostomy cohort was 19%, with the prevalence of leakage increasing over successive pouch changes. The ETB sub-group experienced a significantly lower risk of leakage (13.7%) compared to CIB (29.3%), reflecting a 53.2% lower risk of leakage with ETB (p = 0.03; OR 2.45). Conclusions: This sub-analysis of ileostomy patients confirms that ETB significantly reduces the risk of leakage in this more difficult to manage population compared to CIB, a clinically important consideration in PSC development and overall ostomy management. Evidence-based selection of ostomy barriers can improve patient outcomes, enhance quality of life, and reduce healthcare resource utilization. Full article

Aberrant activation of the Hedgehog (Hh) signaling pathway can be observed in various malignancies, particularly in stroma-rich tumors like pancreatic ductal adenocarcinoma (PDAC). In PDAC, Hh signaling is thought to foster an abundant stroma, making it an appealing target for stoma-targeted therapy. However, the use of Hh antagonists in the clinic has thus far not been successful. To reassess the clinical merit of Hh-targeted therapy in PDAC, we sought to better characterize the role of Hh signaling in tumor-stroma crosstalk. Here, we show that Hh ligands are not prognostic per se in PDAC, despite being associated with the favorable classical molecular subtype. Perturbing Hh ligand expression in PDAC cells can effectively alter their trans-signaling capacity but does not impact tumor growth in vivo. However, co-injecting PDAC cells with Smo-proficient MEFs resulted in a significant reduction in xenograft growth, suggesting that Hh-related effects on tumor growth are largely mediated through the stroma. By analyzing transcriptomic sequencing data from co-cultures, comprising human PDAC cells and mouse fibroblasts treated with a Hh-blocking antibody, we could identify stromal hits that are responsive to Hh ligands. We then leveraged the obtained set of genes to allow patient stratification based on stromal response to Hh ligands. We believe that a subset of PDAC patients may benefit from the use of Hh-targeted therapies and thereby encourage the use of our stratification tool to guide their use in PDAC clinical care.

Background/Objectives: Peristomal skin complications (PSCs) are common among patients with ostomies, significantly impacting quality of life and increasing healthcare utilization. This study aimed to evaluate the effects of the Dermamecum protocol, a risk-stratified educational intervention, on the prevention of PSCs, self-care improvements, health-related quality of life (HRQoL), and patient satisfaction over a 90-day follow-up period. Methods: This prospective cohort study included 305 patients stratified into three risk-based groups (green, yellow, and red paths) according to the Dermamecum protocol. Primary outcomes included PSC rates at 30, 60, and 90 days. Secondary outcomes included self-care scores, HRQoL, and patient satisfaction. Comparative analyses and trend assessments were performed across groups and time points. Temporal trends in PSCs were analyzed using Poisson regression. Results: Early PSC rates were 8.5% at 30 days, with late complications at 7.9% and 6.2% at 60 and 90 days, respectively. No significant differences in PSC rates were observed between paths. Self-care scores improved over time, with stability across groups and domains. HRQoL remained stable, with minor fluctuations in physical and mental components. Patient satisfaction was high across all paths. Poisson regression identified significant temporal trends in PSC rates, with higher risks at 30, 60, and 90 days compared to baseline. Age, BMI, and path assignment (lower risk for the green path) were significant predictors of PSCs. Conclusions: The Dermamecum protocol effectively maintained low PSC rates, supported self-care, and sustained HRQoL and patient satisfaction. These findings highlight the value of risk-stratified, patient-centered interventions in ostomy care. Further studies are needed to validate these results and explore long-term outcomes.

Background: Within 10 years of diagnosis, about 50% of patients with Crohn’s disease (CD) require surgery. Repeated small bowel resections can lead to the development of short bowel syndrome (SBS). It is estimated that 65–75% of CD patients are malnourished. This retrospective observational study was conducted in a Polish reference centre for home parenteral nutrition (HPN). The aim of the study was to investigate the nutritional status and characteristics of patients with CD referred to HPN and to analyse the course of their HPN treatment. Methods: The study group consisted of all adult patients (N = 46) with CD who qualified for HPN between November 2004 and April 2022. Results: The most common indication for HPN was SBS (n = 27; 58.70%), followed by ineffective gastrointestinal nutrition causing progressive malnutrition (N = 9; 19.57%), fistulas (N = 6; 13.04%), and short bowel syndrome and fistulas (N = 4; 8.70%). According to the results of Subjective Global Assessment (SGA), 47.83% (N = 22) of patients were diagnosed with severe malnutrition, followed by 15 patients (32.61%) with moderate malnutrition. Global Leadership Initiative on Malnutrition (GLIM) criteria showed that 71.73% (n = 33) of patients were malnourished on admission to the HPN centre. All patients received parenteral formulas based on individually tailored prescriptions. The results showed that patients with a stoma received statistically significantly higher PN volumes (p = 0.027) and higher amounts of amino acids (p = 0.046) and fat emulsion (p = 0.046). Septic complications were twice as common as mechanical or metabolic complications, although 43.47% of patients had no complications. At the time of data analysis, 19 patients (41.30%) had been successfully weaned from HPN, of whom 12 (26%) achieved nutritional autonomy after 136–1419 days (mean: 560 ± 380.9). Conclusions: Malnutrition is a major problem in CD patients, especially those with SBS. Early nutritional intervention and consideration of artificial nutrition in this study group (HPN) are necessary to prevent the long-term consequences of severe malnutrition. To our knowledge, this was the first study to report on Crohn’s patients referred to long-term HPN. Further studies are needed to assess the impact of HPN on functional, laboratory, and anthropometric outcomes with a view to optimising treatment outcomes. Full article

Backround/Objectives: Colorectal cancer presents a significant quality of life (QoL) challenge as a result of both the disease and its treatments. This study aimed to validate and culturally adapt the Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire (CCF-CaQL) for Serbian-speaking colorectal cancer patients. Methods: The CCF-CaQL offers a detailed assessment of the physical, emotional, social, and functional impacts of the disease. This study, conducted at the University Clinical Center of Serbia, involved 150 colorectal cancer patients undergoing treatment. The translation and adaptation process followed the EORTC Quality of Life Group’s guidelines, ensuring cultural relevance and comprehensibility. Statistical analyses, including Cronbach’s alpha for internal consistency and Pearson’s correlation for concurrent validity, reliability, and known-groups validity, were performed using SPSS and R software. Results: The Serbian version of the CCF-CaQL maintains strong psychometric properties with high internal consistency (Cronbach’s alpha = 0.85) and significant correlations with the FACT-C questionnaire, confirming its validity. Known-groups validity showed distinct variations in QoL scores based on tumor location, stoma presence, and neoadjuvant therapy status, highlighting its sensitivity to different clinical conditions. Conclusions: The CCF-CaQL questionnaire has been skillfully translated, culturally adapted, and carefully validated through psychometric evaluations for Serbian patients diagnosed with colorectal cancer.

Despite a combination of medical and surgical treatments, many patients with perianal Crohn’s disease (CD) continue to experience refractory disease, requiring proctectomy or proctocolectomy, with the creation of a permanent stoma. Although proctectomy is seen as an ultimate treatment aimed at effectively relieving debilitating symptoms and enhancing quality of life, many patients may still face long-term and chronic complications. This narrative review aims to provide an overview of the main complications that patients undergoing proctectomy for CD may experience throughout their lives. Relevant publications addressing complications of proctectomy for refractory perianal CD were searched in the Medline/PubMed, Embase, Cochrane, and LILACS databases. The main long-term complications that patients encounter are related to impaired perineal wound healing, stoma-related issues, sexual and urinary dysfunction, small bowel obstructions, and CD recurrence. These complications negatively affect the quality of life and frequently necessitate further treatment. Patients should receive preoperative counselling regarding the implications of these particular issues, and regular follow-up must be guaranteed to identify any problems early, allowing for prompt treatment.

Surgery continues to be the primary therapeutic approach for patients diagnosed with colon cancer. Unfortunately, postoperative complications have been shown to negatively impact short-term patient outcomes, long-term oncological prognosis, and overall healthcare costs. The risk factors of postoperative complications are multiple, being linked to the patient’s general condition (lifestyle, comorbidities, etc.), the state of the neoplastic disease, as well as the drug and surgical treatments applied. If these factors are associated, the incidence of postoperative complications especially increases in the form of anastomotic leakage, bleeding, infections, postoperative ileus, and stoma-related complications. It is not surprising that these conditions are common causes of prolonged hospitalization in colon surgery, being associated with high rates of morbidity and mortality. Literature data show that the management of the oncological patient, especially if treated surgically and even more so when they develop postoperative complications, is difficult. It is a direct consequence of the fact that such cases can be quite different from each other, so that the development of a common therapeutic protocol is not possible. Therefore, the purpose of this review is to update and highlight the main risk factors for unfavorable outcomes in patients diagnosed and treated surgically for colon cancer, determine what are the most common postoperative complications, and how the course towards severe forms of evolution is influenced by various clinical and biological parameters. Data used for this review were collected from literature published between 2013 and 2025, using several parameters presented in the text. Consequently, the management strategy for these postoperative complications must be primarily based on an early, multidisciplinary and personalized approach, which appear to significantly improve the therapeutic results obtained.

People who have gone through stoma surgery face different problems and difficulties every day, although most of these issues improve significantly with time. The quality of life of ostomy patients has been proven to be strictly related to self-care ability. So, it is essential for patients to properly maintain the ostomy site, including proper daily self-care and regeneration of the skin around the stoma, to avoid stoma-related complications. This review was undertaken using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. The main aim of the literature review was to analyse and present the characteristics of medical products used in ostomy care currently existing on the market. The intervention and management of stoma problems with appliances and accessories are also summarised. This literature review is limited to a critical analysis of the scientific and professional literature and informational materials developed by manufacturers of stoma accessories. Full article

Background/Objectives: An 80-year-old man was admitted to our department after a salvage radical cystectomy for actinic cystitis due to radiotherapy for prostate cancer. He presented with a two-month history of feculent debris in the right stoma and deteriorated general conditions, after a long past medical history of recurrent complicated urinary infections. Methods: Computer tomography (CT) of the abdomen revealed a ureterocolic fistula along the right ureteral pelvic tract. A right percutaneous nephrostomy tube was placed. Due to multiple previous surgeries, several lines of intravenous antibiotic therapies and the overall condition of the patient, a conservative management was preferred. Results: A bovine serum albumin-glutaraldehyde (BioGlue^®) adhesive was inoculated into the right ureter through the stoma to close the fistula. After 24 months, the patient remained asymptomatic with negative follow-up imaging. Conclusions: Given the uniqueness of the management of a ureterocolic fistula, this case offers insight into conservative treatment in frail patients not suitable for major surgery. Full article
