Abdominal hernias in cirrhotic patients: Surgery or conservative treatment? Results of a prospective cohort study in a high volume center: Cohort study.

ABSTRACT: Background:Surgical treatment of abdominal hernias in cirrhotics is often delayed due to the higher morbidity and mortality associated with the underlying liver disease. Some patients are followed conservatively and only operated on when complications occur ("wait and see" approach). The aim of this study is to compare outcomes of cirrhotic patients undergoing conservative non-operative care or elective hernia repair. Methods:A prospective observational study including 246 cirrhotic patients with abdominal hernia was carried out. Patients were given the option to select their treatment: elective hernia repair or conservative non-operative care. Demographics, characteristics of underlying liver disease, type of hernia, complications and mortality were analyzed. During follow-up of patients who opted for the "wait and see" approach, emergency hernia repair was performed in case of hernia complications. Results:Elective hernia repair was performed in 57 patients and 189 patients were kept in conservative care, of which 43 (22.7%) developed complications that required emergency hernia repair. Elective surgery provided better five-years survival than conservative care (80% vs. 62%; p = 0.012). Multivariate analysis identified multiples hernias [Hazards Ratio (HR):6.7, p < 0.001] and clinical follow-up group (HR 3.62, p = 0.005) as risk factors for mortality. Among patients undergoing surgical treatment, multivariate analysis revealed MELD>11 (HR 7.8; p = 0.011) and emergency hernia repair (HR 5.35; p = 0.005) as independent risk factors for 30-day mortality. Conclusions:Elective hernia repair offers an acceptable morbidity and ensures longer survival. "Wait and see" approach jeopardizes cirrhotic patients and should be avoided, given the higher incidence of emergency surgery due to hernia complications.

Project description:BACKGROUND:Preoperative endothelial dysfunction is a predictor of myocardial injury and major adverse cardiac events. Non-cardiac surgery is known to induce acute endothelial changes. The aim of this explorative cohort study was to assess the extent of systemic endothelial dysfunction after major emergency abdominal surgery and the potential association with postoperative myocardial injury. METHODS:Patients undergoing major emergency abdominal surgery were included in this prospective cohort study. The primary outcome was the change in endothelial function expressed as the reactive hyperemia index from 4-24 h after surgery until postoperative day 3-5. The reactive hyperemia index was assessed by non-invasive digital pulse tonometry. Secondary outcomes included changes in biomarkers of nitric oxide metabolism and bioavailability. All assessments were performed at the two separate time points in the postoperative period. Clinical outcomes included myocardial injury within the third postoperative day and major adverse cardiovascular events within 30?days of surgery. RESULTS:Between October 2016 and June 2017, 83 patients were included. The first assessment of the endothelial function, 4-24?h, was performed 15.8 (SD 6.9) hours after surgery and the second assessment, postoperative day 3-5, was performed 83.7 (SD 19.8) hours after surgery. The reactive hyperemia index was suppressed early after surgery and did not increase significantly; 1.64 (95% CI 1.52-177) at 4-24?h after surgery vs. 1.75 (95% CI 1.63-1.89) at postoperative day 3-5, p =?0.34. The L-arginine/ADMA ratio, expressing the nitric oxide production, was reduced in the perioperative period and correlated significantly with the reactive hyperemia index. A total of 16 patients (19.3%) had a major adverse cardiovascular event, of which 11 patients (13.3%) had myocardial injury. The L-arginine/ADMA ratio was significantly decreased at 4-24?h after surgery in patients suffering myocardial injury. CONCLUSION:This explorative pathophysiological study showed that acute systemic endothelial dysfunction was present early after major emergency abdominal surgery and remained unchanged until day 3-5 after the procedure. Early postoperative disturbances in the nitric oxide bioavailability might add to the pathogenesis of myocardial injury. This pathophysiological link should be confirmed in larger studies.

Project description:BACKGROUND:The current guidelines for treatment of carpometacarpal osteoarthritis recommend starting with conservative treatment before a surgical procedure is considered. OBJECTIVE:The objective was to investigate how response to conservative treatment, in terms of pain and hand function, influences the hazard that patients convert to surgical treatment. DESIGN:This was a multicenter, prospective cohort study. METHODS:Participants comprised 701 patients who received 3 months of hand therapy and an orthosis. Pain and function were measured with the Michigan Hand Questionnaire (MHQ) at baseline and at 6 weeks and 3 months follow-up. Conversion to surgical treatment was recorded from clinical records. Joint modeling (a statistical method of combining prediction models) was used to perform the analysis and to calculate hazard ratios (HRs). RESULTS:The joint analytical model showed that both MHQ pain score at a certain point (HR = 0.93; 95% confidence interval [CI] = 0.92-0.94) and change in MHQ pain score (HR = 1.07; 95% CI = 1.06-1.09) during conservative treatment was significantly associated with conversion to surgical treatment. The joint analytical model between functional outcome and conversion to surgical treatment showed only a significant association between MHQ function at a certain point (HR = 0.97; 95% CI = 0.95-0.99), and no significant association between the change in MHQ score for function (HR = 1.0; 95% CI = 1.0-1.0) and conversion to surgical treatment. LIMITATIONS:Missing data might have resulted in biased estimates. CONCLUSIONS:Self-reported pain and function, as well as change in self-reported pain during treatment, were associated with the hazard of conversion to surgical treatment, whereas change in self-reported functioning was not associated with conversion. Because a reduction in pain during conservative treatment appears to decrease the rate of conversion to surgical treatment, it is advised to structurally monitor pain levels during treatment.
