Medical influences, surgical outcomes: Role of common medications on the risk of perforation from untreated diverticular disease

Pre-existing Opioid Use Worsens Outcomes in Patients With Diverticulitis

Background and objective Diverticulitis occurs in 10-25% of patients with diverticulosis. Although opioids can decrease bowel motility, there is scarce data on the effect of chronic opioid use on the outcomes of diverticulitis. In this study, we aimed to explore the outcomes of diverticulitis in patients with pre-existing opioid use. Methods Data between 2008 and 2014 from the National Inpatient Sample (NIS) database was extracted using the International Classification of Diseases, 9th Revision (ICD-9) codes. Univariate and multivariate analyses were used to generate odds ratios (OR). Elixhauser Comorbidity Index (ECI) scores predicting mortality and readmission were calculated based on weighted scores from 29 different comorbidities. Scores were compared between the two groups using univariate analysis. Inclusion criteria included patients with a primary diagnosis of diverticulitis. Exclusion criteria included patients less than 18 years of age, and a diagnosis of opioid use disorder in remission. Studied outcomes included inpatient mortality, complications (including perforation, bleeding, sepsis event, ileus, abscess, obstruction, and fistula), length of hospital stay, and total costs.  Results A total of 151,708 patients with diverticulitis and no active opioid use and 2,980 patients with diverticulitis and active opioid use were hospitalized in the United States from 2008 to 2014. Opioid users had a higher OR for bleeding, sepsis, obstruction, and fistula formation. Opioid users had a lower risk of developing abscesses. They had longer lengths of stay, higher total hospital charges, and higher Elixhauser readmission scores. Conclusion Hospitalized diverticulitis patients with comorbid opioid use are at an elevated risk of in-hospital mortality and sepsis. This could be attributed to complications from injection drug use predisposing opioid users to these risk factors. Outpatient providers caring for patients with diverticulosis should consider screening their patients for opioid use and try offering them medication-assisted treatment to reduce their risk of poor outcomes.

Preoperative Opioid Dose and Surgical Outcomes in Colorectal Surgery

BACKGROUND

The worsening opioid epidemic has led to an increased number of surgical patients with chronic preoperative opioid use. However, the impact of opioids on perioperative outcomes has yet to be fully elucidated. The purpose of this study was to assess the association between preoperative opioid dose and surgical outcomes among colectomy patients.

METHODS

Adult colectomy patients in the IBM MarketScan database (2010-2017) were stratified based on preoperative opioid dose, calculated as the average opioid dose in morphine milligram equivalents (MME) in the 90 days prior to surgery: 0 MME, 1 to 49 MME, and 50 or more MME. The association between preoperative opioid dose and anastomotic leak, the primary outcome of interest, as well as other postoperative complications, was assessed using multivariable regression.

RESULTS

Among 45,515 adult colectomy patients, 71.4% did not use opioids (0 MME), 27.4% had an opioid dose between 1 and 49 MME, and 1.2% had an opioid dose at or above 50 MME. Patients with preoperative opioid use exhibited a higher incidence of anastomotic leak (0 MME: 4.8%, 1-49 MME: 5.5%, ≥50 MME: 8.3%; p trend = 0.001). Multivariable analysis demonstrated a dose-response relationship between preoperative opioids and surgical outcomes, as the odds of anastomotic leak worsened with increasing opioid dose (1-49 MME: OR 1.19, 95% CI 1.08-1.31, p < 0.001; ≥50 MME: OR 1.64, 95% CI 1.20-2.24, p = 0.002). Similar dose-response relationships were seen after risk-adjustment for lung complications, pneumonia, delirium, and 30-day readmission (p < 0.05 for all).

CONCLUSIONS

Providers should exercise caution when prescribing opioids preoperatively, as increasing doses of preoperative opioids were associated with worse surgical outcomes and higher 30-day readmission among adult colectomy patients.

Bowel Perforation During Haemophagocytic Lymphohistiocytosis Treatment with Corticosteroids and Anakinra

We report the use of anakinra to treat a case of a 64-year-old man diagnosed with haemophagocytic lymphohistiocytosis (HLH) with neurological involvement. After the administration of intravenous pulse corticosteroid therapy, immunoglobulin and anakinra the patient showed neurological recovery. However, the recovery was complicated by the perforation of a pre-existing bowel diverticulum. The effect of anakinra on bowel inflammation has not yet been clearly established. It can potentially augment bowel inflammation and contribute to the risk of bowel perforation associated with the concomitant use of corticosteroids.

LEARNING POINTS

Anakinra can potentially augment bowel inflammation.The concomitant use of anakinra and corticosteroids may increase the risk of bowel perforation.Use of anakinra and corticosteroids in patients with pre-existing gastrointestinal diseases requires vigilant observation for abdominal symptoms.

Distinguishing features between patients with acute diverticulitis and diverticular bleeding: Results from the REMAD registry

BACKGROUND

Pathogenesis of acute diverticulitis and diverticular bleeding remains poorly defined, and few data compare directly risk factors for these complications.

AIMS

to assess differences in clinical features, lifestyles factors and concurrent drug use in patients with acute diverticulitis and those with diverticular bleeding.

METHODS

Data were obtained from the REMAD Registry, an ongoing 5-year prospective, observational, multicenter, cohort study conducted on 1,217 patients. Patient- and clinical- related factors were compared among patients with uncomplicated diverticular disease, patients with previous acute diverticulitis, and patients with previous diverticular bleeding.

RESULTS

Age was significantly lower (OR 0.48, 95% CI: 0.34-0.67) and family history of diverticular disease was significantly higher (OR 1.60, 95% CI: 1.11-2.31) in patients with previous diverticulitis than in patients with uncomplicated diverticular disease, respectively. Chronic obstructive pulmonary disease was significantly higher in patients with previous diverticular bleeding as compared with both uncomplicated diverticular disease (OR 8.37, 95% CI: 2.60-27.0) and diverticulitis (OR 4.23, 95% CI: 1.11-16.1).

CONCLUSION

This ancillary study from a nationwide Registry showed that some distinctive features identify patients with acute diverticulitis and diverticular bleeding. These information might improve the assessment of risk factors for diverticular complications.

Risk factors for endoscopic severity of diverticular disease of the colon and its outcome: a real-life case-control study

BACKGROUND

Diverticular disease is an increasing global problem.

AIMS

To assess the factors associated with the severity of diverticular disease and its outcome, analyzing a real-life population.

METHODS

A cohort of patients, submitted to colonoscopy from 1 January 2012 to 30 April 2018 was revised. The endoscopic severity of diverticular disease was scored according to the Diverticular Inflammation and Complications Assessment (DICA) classification.

RESULTS

A cohort of 11 086 patients was identified during the study period, 5635 with diverticulitis and 5451 without diverticulosis. Blood hypertension, diabetes and angiotensin receptor blocker users occurred more frequently in the study group, while the prevalence of colorectal cancer (CRC) was significantly lower. Age >70 years, BMI >30 and blood hypertension were factors independently related to the presence of diverticulosis, while diabetes and CRC were significantly associated with the absence of diverticulosis. Female sex, age, smoke, appendectomy, proton-pump inhibitors and acetyl-salicylic acid use were directly related to the severity of diverticular disease, while CRC and colonic polyp occurrence were inversely related to the severity of diverticular disease, significantly. Female sex, age >70 years and smoke were significantly related to the severity of diverticular disease. CRC and colonic polyps were significantly less in DICA 3 patients. DICA 3 patients were more often symptomatic, at higher risk of hospital admission, longer hospital stay and higher mean costs.

CONCLUSIONS

Several factors are associated with the severity of diverticular disease according to the DICA classification. The DICA classification is also predictive of the outcome of the disease in terms of hospital admission, stay and costs.

Sex differences in risk factors of uncomplicated colonic diverticulosis in a metropolitan area from Northern China

As the world’s most populated and rapidly aging country, there is limited information on sex-related differences in factors regarding uncomplicated colonic diverticulosis in China. We aimed to investigate sex differences in individual risk factor in a northern metropolis. Patients with colonic diverticulosis who underwent indicated colonoscopy were queried with respect to medical history and demographic features. Demographic information, life style factors and co-morbidities were retrieved from a prospective dataset. Multiple regression analyses were performed to determine precipitating factors of diverticula. Of 4,386 enrolled patients, colonic diverticulosis were detected in 218 cases (4.97%). Multiple logistic regression analysis implicated increasing age (OR = 1.05, 95%CI 1.03–1.06, P < 0.001), red meat ≥100 g/d (OR = 2.53, 95%CI 1.72–3.70, P < 0.001), smoking (OR = 2.14, 95%CI 1.05–4.33, P = 0.035), rheumatologic diseases (OR = 3.38, 95%CI 1.09–10.5, P = 0.035) and NSAIDs (OR = 2.11, 95%CI 1.12–3.97, P = 0.020) were significantly associated with diverticulosis in men, whilst advancing age (OR = 1.03, 95%CI 1.01–1.05, P = 0.013), BMI (OR = 1.12, 95%CI 1.04–1.19, P = 0.001), smoking (OR = 10.2, 95%CI 2.81–37.4, P < 0.001), rheumatologic diseases (OR = 8.04, 95%CI 3.05–21.2, P < 0.001), hypertension (OR = 1.76, 95%CI 1.01–3.06, P = 0.047), colonic polyps (OR = 3.12, 95%CI 1.82–5.36, P < 0.001) and antihypertensive medications (OR = 2.99, 95%CI 1.66–5.39, P < 0.001) in women. In conclusion, it is pivotal to take account of differentially sex-related factors in regard to the development of uncomplicated colonic diverticulosis.
