S158 Predictors of In-Hospital Mortality in Acute Colonic Diverticulitis

Background & Aims: Diverticulitis is often diagnosed in outpatients, yet little evidence exists on diagnostic evidence and demographic/clinical features in various practice settings. We assessed variation in clinical characteristics and diagnostic evidence in inpatients, outpatients, and emergency department cases and effects of demographic and clinical variables on presentation features.Methods: In a retrospective cohort study of 1749 patients in an integrated health care system, we compared presenting features and computed tomography findings by practice setting and assessed independent effects of demographic and clinical factors on presenting features.Results: Inpatients were older and more often underweight/normal weight and lacked a diverticulitis past history and had more comorbidities than other patients. Outpatients were most often Hispanic/Latino. The classical triad (abdominal pain, fever, leukocytosis) occurred in 78 (38.6%) inpatients, 29 (5.2%) outpatients and 34 (10.7%) emergency department cases. Computed tomography was performed on 196 (94.4%) inpatients, 110 (9.2%) outpatients and 296 (87.6%) emergency department cases and was diagnostic in 153 (78.6%) inpatients, 62 (56.4%) outpatients and 243 (82.1%) emergency department cases. Multiple variables affected presenting features. Notably, female sex had lower odds for the presence of the triad features (odds ratio [95% CI], 0.65 [0.45-0.94], P<0.05) and increased odds of vomiting (1.78 [1.26-2.53], P<0.01). Patients in age group 56 to 65 and 66 or older had decreased odds of fever (0.67 [0.46-0.98], P<0.05) and 0.46 [0.26-0.81], P<0.01), respectively, while ≥1 co-morbidity increased the odds of observing the triad (1.88 [1.26-2.81], P<0.01).Conclusion: There was little objective evidence for physician-diagnosed diverticulitis in most outpatients. Demographic and clinical characteristics vary among settings and independently affect presenting features.Abbreviations: AD: acute colonic diverticulitis; BMI: body mass index; CT: computed tomography; ED: emergency department; IBS: irritable bowel syndrome; ICD-9-CM: International Classification of Diseases, 9th Revision, Clinical Modification; IP: inpatient; KPSC: Kaiser Permanente Southern California; OP: outpatient.

Acute Colonic Diverticulitis

Abstract Background and study aims The relationship between acute colonic diverticulitis and colorectal cancer (CRC) is unclear, but colonoscopy is recommended to exclude malignancy. We compared the detection rates for colorectal neoplasia in patients with colonic diverticulitis and asymptomatic patients who had positive fecal immunochemical tests (FITs). Patients and methods In total, 282 patients with acute colonic diverticulitis were hospitalized in our hospital from February 2011 to December 2019. Of them, 143 patients with diverticulitis and 1819 with positive FITs patients during the same period underwent colonoscopy without a prior colonoscopy within 5 years. We retrospectively compared these patients in terms of the invasive CRC rate, advanced neoplasia detection rate (ANDR), adenoma detection rate (ADR), and polyp detection rate (PDR). Results Compared to the diverticulitis group, the FIT-positive group had a significantly higher CRC rate (0 vs 2.7 %, P = 0.0061), ANDR (5.6 vs. 14.0 %, P = 0.0017), ADR (19.6 vs. 53.2 %, P < .0001), and PDR (44.1 vs. 91.0 %, P < .0001). Using 1:1 propensity score matching based on age and sex, we obtained 276 matched patients in both groups. After matching, no difference was found in the CRC rate (0 vs 0.7 %) or ANDR (5.8 vs 7.3 %) between groups, but the ADR and PDR were significantly higher in the FIT-positive group (20.3 vs 43.5 %, P < .0001; 45.7 % vs 86.2 %, P < .0001). Conclusion Patients with acute diverticulitis had lower ADRs and PDRs than patients with positive FITs.

Acute Colonic Diverticulitis

Objective: To investigate the diagnostic potential of neutrophil-to-lymphocyte count ratio (NLCR) for acute diverticulitis. Summary of Background Data: We evaluated NLCR in patients with acute colonic diverticulitis who were treated with conservative and surgical treatments. Methods: A total of 205 patients who underwent surgical treatment or conservative management of acute diverticulitis between 2012 and 2016 were reviewed. Patients' age; sex; hospital days; co-morbidity; complication; period of use of antibiotics; treatment method; body temperature; and initial laboratory results such as neutrophil count, lymphocyte count, NLCR, and serum levels of C-reactive protein (CRP) were assessed. Results: The median ages of the conservative and surgical treatment groups were 46 and 68 years, respectively. Median CRP and glucose levels were high in acute colonic diverticulitis patients who underwent surgical treatment (P < 0.001, P < 0.001). Albumin level was low in the surgical treatment group (P < 0.001). NLCR was significantly different in both groups (conservative management vs surgical treatment, 4.1 mg/L versus 8.5 mg/L; P < 0.001). Median white blood cells was 11.36 × 109/L in the conservative management group and 14.0 × 109/L in the surgical treatment group, with no significance (P = 0.071). Multivariate analysis revealed that NLCR >10.21 [odds ratio (OR) = 5.613, P = 0.022]; CRP >17.23 mg/L (OR = 4.241, P = 0.006); and albumin ≤3.5 (OR = 4.192, P = 0.036) were significant for acute colonic diverticulitis patients. Conclusion: NLCR, CRP, and albumin levels were significantly associated with acute colonic diverticulitis in the surgical treatment group, and NLCR was the most powerful predictive marker of severe acute colonic diverticulitis.

Acute Colonic Diverticulitis

Abstract Aims To compare the demographic and prognostic outcomes of right-sided versus left-sided acute colonic diverticulitis Methods We performed a systematic review in accordance with the PRISMA statement standards to identify all observational studies comparing demographic factors and outcomes of right-sided versus left-sided acute colonic diverticulitis. We used the ROBINS-I tool to assess the risk of bias of included studies. Random effects modelling was applied to calculate pooled outcome data. Results Analysis of 2933 patients from nine studies suggests that right-sided diverticulitis affects younger patients (MD:-14.16,P<0.00001) and more male patients (OR:1.33,P=0.02) compared with left-sided diverticulitis. Smoking (OR:2.23,P<0.0001), alcohol consumption (OR:1.85,P=0.002) and co-morbidity (OR:0.21,P<0.00001) were more common in patients with right-sided diverticulitis. The risk of complicated diverticulitis was lower in the right-sided group (OR:0.21,P=0.001). More patients in the right-sided diverticulitis group had modified Hinchey stage I disease (OR:10.21,P<0.0001) while more patients in the left-sided group had stage II (OR:0.19,P<0.00001), stage III (OR:0.08,P=0.009) or stage IV disease (OR:0.02,P<0.00001). Right-sided diverticulitis was associated with a lower risk of recurrence (OR:0.49,P=0.04), failure of conservative management (OR:0.14,P=0.0006), the need for emergency surgery (OR:0.13,<0.00001) and shorter length of hospital stay (MD:-1.70,P=0.02). Conclusions Right-sided acute colonic diverticulitis predominantly affects younger male patients compared with left-sided disease and is associated with favourable outcomes as indicated by the lower risk of complications, failure of conservative management, need for emergency surgery, recurrence, and shorter length of hospital stay. More studies are required to compare the postoperative outcomes in patients with right-sided and left-sided diverticulitis undergoing emergency surgery.
