C-reactive protein is a predictive factor for complications after incisional hernia repair using a biological mesh

The long-term impact of vaginal surgical mesh devices on pain clinic and psychological service referrals, anti-inflammatory testing and pelvic scans in UK primary care: A cohort study with the Clinical Practice Research Datalink

OBJECTIVE

To examine long-term complications in women with stress urinary incontinence (SUI) and pelvic organ prolapse (POP), with and without surgical mesh implants.

DESIGN

Longitudinal open cohort study from 1 April 2006 (or 1 April 2012) to 30 November 2018.

SETTING

The Clinical Practice Research Datalink (CPRD) Gold database, which is linked to Hospital Episodes Statistics (HES) inpatient data, the HES Diagnostic Imaging Dataset (DID), Office for National Statistics mortality data and Index of Multiple Deprivation socio-economic status data.

SAMPLE

Women aged ≥18 years with a diagnostic SUI/POP Read code.

METHODS

Rates are estimated using negative binomial regression.

MAIN OUTCOME MEASURES

Rates of referrals for: psychological and pain services; urinalysis, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) testing; and pelvic ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) scans.

RESULTS

A cohort of 220 544 women were eligible for inclusion; 74% (n = 162 687) had SUI, 37% (n = 82 123) had POP and 11% (n = 24 266) had both. Rates of psychological referrals and CT scans were lower in women with SUI mesh surgery, but this was offset by higher rates of CRP testing in women with SUI or POP mesh, MRI scans in women with SUI mesh, and urinalysis testing and referrals to pain clinics for women with POP mesh.

CONCLUSIONS

Our results suggest a higher burden of morbidity in women with SUI/POP mesh surgery, and that these women may require ongoing follow-up in the primary care setting.

Systemic immune-inflammation index within the first postoperative hour as a predictor of severe postoperative complications in upper abdominal surgery: a retrospective single-center study

Background

Systemic pro-inflammatory factors play a critical role in mediating severe postoperative complications (SPCs) in upper abdominal surgery (UAS). The systemic immune-inflammation index (SII) has been identified as a new inflammatory marker in many occasions. The present study aims to determine the association between SII and the occurrence of SPCs after UAS.

Methods

Included in this study were 310 patients with upper abdominal tumors who received UAS and subsequently were transferred to the anesthesia intensive care unit between November 2020 and November 2021 in Nanjing Drum Hospital. SPCs, including postoperative pulmonary complications (PPCs), major adverse cardiac and cardiovascular events, postoperative infections and delirium, were recorded during the hospital stay. The clinical features of the patients with and without SPCs were compared by Student’s t-test or Fisher’s exact test as appropriate. Risk factors associated with SPC occurrence were evaluated by univariable and multivariable logistic regression analyses. Receiver operating characteristic (ROC) curve analysis was used to establish a cut-off level of SII value to predict SPCs.

Results

Of the 310 patients receiving UAS, 103 patients (33.2%) presented at least one SPC, including PPCs (n = 62), adverse cardiovascular events (n = 22), postoperative infections (n = 51), and delirium (n = 5). Both preoperative SII and 1-h postoperative SII in patients with SPCs were significantly higher than those in patients without SPCs. Multivariate analysis showed that 1-h postoperative SII was an independent predictor for SPC occurrence (OR = 1.000, 95% CI 1.000–1.000, P = 0.007), together with postoperative C-reactive protein, postoperative arterial lactate, postoperative oxygenation-index and older age. The ROC curve showed that the optimal cutoff value of 1-h postoperative SII to predict SPCs was 754.6078 × 10⁹/L, with an 88.3% sensitivity and a 29% specificity. Multivariate analysis also confirmed that 1-h postoperative SII > 754.6078 × 10⁹/L was associated with increased SPC occurrence (OR = 2.656, 95% CI 1.311–5.381, P = 0.007).

Conclusion

Our findings demonstrated an association between the higher level of 1-h postoperative SII and SPCs, suggesting that 1-h postoperative SII, especially categorized 1-h postoperative SII using cutoff value, may be a useful tool for identifying patients at risk of developing SPCs.
