Prospectively Assigned AAST Grade versus Modified Hinchey Class and Acute Diverticulitis Outcomes

Small bowel obstruction outcomes according to compliance with the World Society of Emergency Surgery Bologna guidelines

BACKGROUND

Small bowel obstruction (SBO) is a common surgical emergency associated with substantial morbidity, hospital length of stay (LOS), and healthcare cost. The World Society of Emergency Surgery (WSES) Bologna guidelines provide evidence-informed recommendations for managing adhesive SBO, promoting timely surgical intervention (or non-operative management (NOM) when ischaemia, strangulation, or peritonitis are absent). However, guideline adoption and its impact on outcomes remain under studied. Compliance with the Bologna guidelines was evaluated to determine the impact of compliance on outcomes.

METHODS

SnapSBO, a prospective, multicentre, time-bound, observational cohort study, captured data on patients with adhesive SBO across diverse healthcare settings and patient populations. Patient care was categorized into: successful NOM, surgery after an unsuccessful appropriate trial of NOM (NOM-T), and direct to surgery (DTS). Compliance with diagnostic, therapeutic, and postoperative Bologna guideline recommendations was assessed as either complete or partial. Primary outcomes included adherence to the Bologna guidelines, LOS, complications, and the incidence of the composite metric 'optimal outcomes' (LOS ≤5 days, discharge without complications, and no readmission within 30 days).

RESULTS

Among 982 patients with adhesive SBO, successful NOM occurred in 561 (57.1%), 224 (22.8%) underwent NOM-T, and 197 (20.1%) proceeded DTS. The mean(s.d.) LOS was 5.3(9.0), 12.9(11.4), and 7.7(8.0) days respectively (P < 0.001). Optimal outcomes were achieved in 61.0%, 16.1%, and 37.6% respectively (P < 0.001) and full guideline compliance was observed in 17.2%, 10.1%, and 0.4% respectively.

CONCLUSION

Patients with adhesive SBO whose care was aligned with the Bologna guidelines had a shorter LOS and a greater incidence of optimal outcomes. Addressing evidence-to-practice gaps through implementation strategies that consider contextual factors will enhance guideline adoption and patient outcomes.

The Predictive Value of Serum Sodium Levels and Inflammatory Markers in Differentiating Complicated and Uncomplicated Acute Diverticulitis: A Retrospective Cohort Study

Background and Objectives: This study aimed to investigate the role of serum sodium levels as an independent predictor of complications in acute diverticulitis and to evaluate their diagnostic value alongside inflammatory markers. Materials and Methods: A total of 134 patients diagnosed with acute diverticulitis between June 2018 and January 2024 at the Erol Olçok Training and Research Hospital were retrospectively analyzed. Complicated diverticulitis was defined based on the presence of an abscess, perforation, fistula, or obstruction classified as Hinchey stage II-IV. Serum sodium, CRP, and WBC levels were assessed for their predictive value. Statistical analyses included ROC analysis to determine optimal thresholds and logistic regression to evaluate independent predictors. Results: A total of 29.1% of the patients were classified as having complicated diverticulitis. Serum sodium levels were significantly lower in the complicated group (median: 133 mmol/L, p < 0.001), whereas CRP (median: 86.5 mg/L, p < 0.001) and WBC levels (median: 11.62 × 103/µL, p = 0.001) were higher. The ROC analysis identified <135.5 mmol/L as the optimal threshold for serum sodium, with a 94.9% sensitivity and 94.7% specificity, making it the strongest predictor. The logistic regression revealed that each unit decrease in serum sodium increased the risk of complications by 5.7 times (p < 0.001). Conclusions: Serum sodium levels are an independent and strong predictor of complications in acute diverticulitis. When used alongside CRP and WBC levels, diagnostic accuracy can be enhanced, leading to improved patient management.

Emergency medicine updates: Acute diverticulitis

INTRODUCTION

Acute diverticulitis is a condition commonly seen in the emergency department (ED). Therefore, it is important for emergency medicine clinicians to be aware of the current evidence regarding the diagnosis and management of this disease.

OBJECTIVE

This paper evaluates key evidence-based updates concerning acute diverticulitis for the emergency clinician.

DISCUSSION

Diverticulitis is a complication of diverticulosis and most commonly affects the sigmoid and descending colon in Western countries. History and examination can suggest the diagnosis, with abdominal pain and tenderness in the left lower quadrant being the most common symptom and sign, respectively. Change in bowel habits and fever may also occur. Laboratory testing may demonstrate leukocytosis or an elevated C-reactive protein. Imaging options can include computed tomography (CT) of the abdomen and pelvis with intravenous contrast, magnetic resonance imaging (MRI), or ultrasound (US), though most classification systems for diverticulitis incorporate CT findings. While the majority of diverticulitis cases are uncomplicated, complications may affect up to 25% of patients. Treatment of complicated diverticulitis requires antibiotics and surgical consultation. Antibiotics are not required in select patients with uncomplicated diverticulitis. Appropriate patients for supportive care without antibiotics should be well-appearing, have pain adequately controlled, be able to tolerate oral intake, be able to follow up, have no complications, and have no immunocompromise or severe comorbidities.

CONCLUSIONS

An understanding of literature updates can improve the ED care of patients with acute diverticulitis.

Acute Colonic Diverticulitis: CT Findings, Classifications, and a Proposal of a Structured Reporting Template

Acute colonic diverticulitis (ACD) is the most common complication of diverticular disease and represents an abdominal emergency. It includes a variety of conditions, extending from localized diverticular inflammation to fecal peritonitis, hence the importance of an accurate diagnosis. Contrast-enhanced computed tomography (CE-CT) plays a pivotal role in the diagnosis due to its high sensitivity, specificity, accuracy, and interobserver agreement. In fact, CE-CT allows alternative diagnoses to be excluded, the inflamed diverticulum to be localized, and complications to be identified. Imaging findings have been reviewed, dividing them into bowel and extra-intestinal wall findings. Moreover, CE-CT allows staging of the disease; the most used classifications of ACD severity are Hinchey's modified and WSES classifications. Differential diagnoses include colon carcinoma, epiploic appendagitis, ischemic colitis, appendicitis, infectious enterocolitis, and inflammatory bowel disease. We propose a structured reporting template to standardize the terminology and improve communication between specialists involved in patient care.

Artificial intelligence in colorectal surgery: an AI-powered systematic review

Artificial intelligence (AI) has the potential to revolutionize surgery in the coming years. Still, it is essential to clarify what the meaningful current applications are and what can be reasonably expected. This AI-powered review assessed the role of AI in colorectal surgery. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-compliant systematic search of PubMed, Embase, Scopus, Cochrane Library databases, and gray literature was conducted on all available articles on AI in colorectal surgery (from January 1 1997 to March 1 2021), aiming to define the perioperative applications of AI. Potentially eligible studies were identified using novel software powered by natural language processing (NLP) and machine learning (ML) technologies dedicated to systematic reviews. Out of 1238 articles identified, 115 were included in the final analysis. Available articles addressed the role of AI in several areas of interest. In the preoperative phase, AI can be used to define tailored treatment algorithms, support clinical decision-making, assess the risk of complications, and predict surgical outcomes and survival. Intraoperatively, AI-enhanced surgery and integration of AI in robotic platforms have been suggested. After surgery, AI can be implemented in the Enhanced Recovery after Surgery (ERAS) pathway. Additional areas of applications included the assessment of patient-reported outcomes, automated pathology assessment, and research. Available data on these aspects are limited, and AI in colorectal surgery is still in its infancy. However, the rapid evolution of technologies makes it likely that it will increasingly be incorporated into everyday practice.

Value of computed tomography scores in complicated acute diverticulitis

BACKGROUND

Diverticular disease remains one of the most common conditions in the western world. Up to 25% of patients with diverticular disease require hospitalization, 15-30% of those of which require surgical intervention. CT scoring systems have been proposed as means to drive assessment and stratify patients necessitating hospital intervention. To assess and correlate CT scoring systems with clinical and surgical outcomes.

METHODS

Retrospective cohort analysis at a single institution. Single institutional assessment with patients presenting to emergency with a CT diagnosed episode of acute diverticulitis. One hundred and eighty-nine patients were included in the study, 61% of which were male. Patient demographics, comorbidities, medications, biochemistry and inflammatory markers, type of complication following acute diverticulitis, operative/procedural intervention, hospital outcome and mortality were measured. CT scoring systems assessed included modified Hinchey, modified Neff, World Society of Emergency Surgery (WSES) and modified Siewert scoring systems.

RESULTS

Majority of patients had left-sided diverticulitis (91%) with localized air (88%) and pericolic abscess (49%) the most common radiological findings. 28% of patients required radiological and/or surgical management with 12% requiring intensive care unit (ICU) admission. There was a general trend for surgical/radiological intervention as the scores increased in severity. The four scoring systems were found to be statistically significant predictors of any intervention and of ICU admission with minimal statistical differences across the different scoring systems.

CONCLUSION

Radiological CT scores for complicated diverticulitis are at best, moderate predictors of clinical and surgical outcomes and may serve to guide management with minimal statistical differences across different scores.
