Aims: Between 11 to 14% of patients with locally advanced rectal cancer (LARC) have positive lateral pelvic lymph nodes (LPLN) at diagnosis, related to a worse prognosis with a 5-year survival rate between 30 to 40%. The best treatment choice for this group of patients is still a challenge. The optimal radiotherapy (RT) dose for LPLN patients has been investigated. Methods: We retrospectively collected data from LARC patients with LPLN at the primary staging MRI, treated in our center from March 2003 to December 2020. Patients underwent a neoadjuvant concomitant chemo-radiotherapy (CRT) treatment on the primary tumor (T), mesorectum, and pelvic nodes, associated with a fluoride-based chemotherapy. The total reached dose was 45 Gy at 1.8 Gy/fr on the elective sites and 55 Gy at 2.2 Gy/fr on the disease and mesorectum. Patients were divided in two groups based on whether they received a simultaneous integrated RT boost on the LPLN or not. Overall Survival (OS), Disease Free Survival (DFS), Metastasis Free Survival (MFS), and Local Control (LC) were evaluated in the whole group and then compared between the two groups. Results: A total of 176 patients were evaluated: 82 were included in the RT boost group and 94 in the non-RT boost group. The median follow-up period was 57.8 months. All the clinical endpoint (OS, DFS, MFS, LC), resulted were affected by the simultaneous integrated boost on LPLN with a survival rate of 84.7%, 79.5%, 84.1%, and 92%, respectively, in the entire population. From the comparison of the two groups, there was a statistical significance towards the RT boost group with a p < 0.006, 0.030, 0.042, 0.026, respectively. Conclusions: Concomitant radiotherapy boost on positive LPLN has shown to be beneficial on the survival outcomes (OS, DFS, MFR, and LC) in patients with LARC and LPLN. This analysis demonstrates that a higher dose of radiotherapy on positive pelvic lymph nodes led not only to a higher local control but also to a better survival rate. These results, if validated by future prospective studies, can bring a valid alternative to the surgery dissection without the important side effects and permanent disabilities observed during the years.

Patients with Crohn's disease experience an increased risk of postoperative complications and disease recurrence. The aim of this study was to investigate the role of the risk factors in determining these outcomes and whether preoperative removal of some of these risk factors would optimize the results. We conducted a retrospective study analyzing a consecutive series of 255 patients who underwent surgical resection for Crohn's disease between 2010 and 2020. We considered short- and long-term endpoints, such as postoperative complications categorized according to the Clavien–Dindo classification and the appearance of surgical and endoscopic postoperative recurrence. Univariable and multivariable analyses showed that multiple and extensive localizations increased the incidence of postoperative complications (OR = 2.19; 95% CI 1.05–4.5; p = 0.035 and OR = 1.015; 95% CI 1.003–1.028; p = 0.017 for each cm of resected segment, respectively). Regarding theoretically modifiable factors, preoperative hypoalbuminemia (for each g/L reduction) increased the risk of complications with an OR = 1.1; 95% CI 1.02–1.12; p = 0.003. Preoperative steroid therapy exerted a similar effect, with an OR = 2.6; 95% CI 1.1–5.9; p = 0.018. Modifying these last two risk factors by improving the nutritional status or discontinuing steroid therapy significantly reduced complications.Microscopic positivity of the resection margins was a risk factor for surgical recurrence (OR = 8.7; 95% CI 1.9–40; p = 0.05). Based on the results of the present study, surgeons must examine modifiable risk factors, and careful preoperative tailored management may reduce postoperative complications and disease recurrence.

Chronic pouchitis occurs in about 50% of patients undergoing a restorative proctocolectomy for ulcerative colitis. This affection represents a significant therapeutic challenge, particularly for symptomatic patients who do not respond to antibiotic treatments and biologic therapies. Several dietary approaches, including low FODMAP diets and the Mediterranean diet, have shown promising results in improving symptoms and disease burden. The rationale for dietary intervention lies in the reduction in inflammation and modulation of gut microbiota. However, conflicting results and methodological heterogeneity jeopardize the transition of these approaches from the field of research to clinical practice. Together with a nutritional approach, innovative methods of microbiota modulation, including probiotics and fecal microbiota transplantation, are emerging as safe and effective strategies in managing chronic pouchitis. This narrative review analyzes recent advancements in nutritional therapies and microbiota modulation as innovative and complementary approaches for managing chronic pouchitis. After examining microbiota modulation strategies, specifically the effectiveness of probiotics, prebiotics, and fecal microbiota transplantation in restoring microbial diversity and their potential role in alleviating symptoms, the review assesses the available clinical evidence concerning dietary interventions and their impact on gut microbiota. A comprehensive understanding of interventions aimed at modulating the microbiota is crucial for enhancing the effectiveness of conventional therapies. Such strategies may lead to significant improvements in patients’ quality of life and their perception of the disease. However, the variability in microbiota composition, the use of restrictive diets, and the lack of standardized methods for evaluating these interventions remain significant challenges. Future research is essential to improve our understanding of the underlying mechanisms and optimize clinical application.

Malakoplakia is a rare entity on inflammatory base that mostly occurs in immunocompromised individuals which is thought to be secondary to a bactericidal defect in macrophages. The genitourinary tract is typically affected. The appendix is a very rare localization. We report a case of malakoplakia in the appendix of a young healthy patient with a recent history of abdominal pain associated with diarrhea and nausea. The colonscopy and CT scan showed an extramucosal bumping mass pressing on the cecum and covered by normal mucosa. The patient underwent to laparoscopic appendectomy. The histology showed a malakoplakia of the appendix. Gastrointestinal localization of malakoplakia is often associated with preexisting diseases, which are probably responsible for an immune disorder underlying the etiopathogenesis of the disease. However, in our case, the patient had no comorbidities. Probably, a clinically unknown immune predisposition plays an important role. Further studies are needed to clarify this nexus.

Objective: This study investigated the radiological, clinical, and surgical factors linked to the risk of endoscopic recurrence following ileocolic resection for Crohn’s disease. Materials and Methods: We conducted a retrospective analysis of data from all patients who underwent primary ileocecal resection for Crohn’s disease in a single colorectal unit between 2004 and 2020. We analyzed the potential risk factors subdivided by the clinical, radiological, and surgical factors associated with morphological recurrence, as detected by endoscopy within 2 years after surgery. Cox regression was employed to ascertain the risk factors associated with such recurrence. Results: In total, 63 patients were included, and 24 (38%) had endoscopic recurrence. The age of the patient at the time of surgery was identified as a significant clinical factor associated with the risk of recurrence (HR: 1.04; p = 0.003), indicating that the probability of recurrence increases by 1% as the surgical age increases each year. The radiological factors associated with an increased risk of recurrence included localization in the distal ileum (HR: 3.526; p = 0.015), the number of pathological small-bowel segments affected by the disease (HR: 1.15; p = 0.004), and the total length of the pathological intestinal segment (HR: 1.002; p = 0.014). The presence of granulomas (HR: 6.003; p = 0.004) and the length of the resected bowel (HR: 1.01; p = 0.003) were surgical factors associated with a higher risk of recurrence. Conclusions: This study delineated several clinical, radiological, and surgical factors that serve as predictors for the endoscopic recurrence of Crohn’s disease after surgery.

Background Acute severe ulcerative colitis (ASUC) affects up to 25% of patients with ulcerative colitis, with 20–40% ultimately requiring urgent subtotal colectomy. Despite established guidelines on the medical management of ASUC, current recommendations from guidelines do not address the procedural and technical aspects of the operation itself. Significant variability in surgical practice has been documented even among high-volume Italian inflammatory bowel disease (IBD) centers. Methods A national e-consensus was conducted using a modified Delphi method. Fifteen expert colorectal surgeons members of Italian Society of Colorectal Surgery (SICCR) from 15 high volume IBD surgical Units (13 Italian, 2 international) evaluated 14 statements across four procedural domains. Each statement was rated on a 4-point ordinal scale (1 = full agreement; 4 = disagreement). Statements achieving > 75% full agreement or ≥ 80% combined full agreement + agreement were classified as appropriate. Uncertain statements were revised and resubmitted for a second voting round. Results In the first round, 8 of 14 statements achieved consensus; 6 were classified as uncertain and revised for resubmission. All six revised statements achieved consensus in the second round. The final document comprises 11 consensus statements addressing: management of the rectal stump and drainage (5 statements), role of the greater omentum (1 statement), laparoscopic versus open surgical approach (3 statements), and management of the mesocolon (2 statements). Conclusions This e-consensus provides the first structured, evidence-graded procedural guidance for urgent subtotal colectomy in acute severe ulcerative colitis (ASUC), covering technical aspects not addressed by current international guidelines. These recommendations aim to reduce practice variability and support standardized surgical decision-making across IBD centers.
