The clinical relevance of an inflamed appendix in Crohn's disease

BACKGROUND AND AIMS

An appendectomy for appendiceal inflammation has been suggested to ameliorate the clinical course of patients with ulcerative colitis (UC). In contrast, for Crohn's disease (CD) an inverse association has been suggested with a higher incidence of CD and worse prognosis after appendectomy. The aim of this study was to analyse the clinical relevance of an inflamed appendix in CD patients undergoing ileocoecal resection (ICR).

METHODS

All consecutive patients undergoing primary ICR between 2007 and 2018 were considered for inclusion. Microscopic data of available appendiceal resection specimens (n=99) were revised by a dedicated IBD-pathologist and scored as inflamed or not inflamed. Eighteen patients had a previous appendectomy. Pathological findings were correlated with disease characteristics and recurrence rates (clinical, endoscopic and intervention-related).

RESULTS

In total, 117 patients were included: 77 (65.8%) females with a median age of 30 years [IQR 24 - 43] with a median follow up of 102 months [IQR 76-114]. Of patients without previous appendectomy (n=99), 39% had an inflamed appendix. No significant differences in disease characteristics (e.g. disease location, behaviour, time to surgery) or prognosis could be demonstrated between the two groups. In contrast, previous appendectomy (n=18) was associated with penetrating disease and numerically shorter disease duration at the time of resection. Furthermore, a trend was seen towards a stronger association with postoperative recurrence.

CONCLUSION

The current study could not confirm a different prognosis for CD patients with and without an inflamed appendix. In contrast, in patients with a previous appendectomy a trend was seen towards increased postoperative recurrence, which might be related to the higher incidence of penetrating disease.

Dramatic rapid recovery after transcathater aortic valve implantation in patient with ischemic hepatitis and hyperbilirunemia

Transcatheter aortic valve implantation (TAVI) is widely used in high-risk patients with severe symptomatic aortic valve stenosis (AS). The use of traditional surgical aortic valve replacement (SAVR) significantly increases the risk of complications in chronic liver failure with the release of many vasoactive and cytotoxic substrates. In patients with ischemic hepatitis or liver dysfunction along with the severe AS, TAVI may be advantageous due to its minimally invasive nature. However, there is limited information about the outcome of TAVI in a patient with both hepatic and multisystem dysfunction. We report this case demonstrating dramatic result of TAVI in a patient in extremely poor clinical condition due to ischemic hepatitis and hyperbilirunemia.

Predictors and incidence of access site complications in transcatheter aortic valve implantation with the use of new delivery systems

Objectives:

The aim of this single-center study was to assess the incidence and predictors of in-hospital access site complications related to transcatheter aortic valve implantation (TAVI) performed with new delivery systems in our hospital which has the largest case series in Turkey.

Materials and method:

We performed successful TAVI with the Edwards Sapien XT valve to 127 (46 male) patients via a transfemoral (121), trans-subclavian (5) and transapical (1) approach. Access site complications were defined according to the Valve Academic Research Consortium (VARC) end-point definitions.

Results:

Vascular complications occurred in 10.1% of patients. There was negative correlation between vascular complications and diameter of the common femoral artery (r = − 0.301, p=0.004), external iliac artery (r = − 0.327, p=0.004) and common iliac artery (r = − 0.324, p=0.004), but positive correlation between diabetes (r =0.240, p=0.008), sheath to femoral artery ratio (SFAR), sheath to external iliac artery ratio (SEIAR), procedure time, discharge time and the Society of Thoracic Surgeons (STS) score (respectively; r=0.339, 0.001, 0.527, 0.361, 0.289, p=0.003, 0.001, 0.001, 0.001, 0.002). The incidence of vascular complications was significantly higher in patients with diabetes and a high STS score. VARC bleeding complications occurred in 11.7 % of patients. The learning curve pointing out the importance of experience was significantly important in decreasing both bleeding and vascular complications.

Conclusions:

In this study, we demonstrated that major vascular complications related to TAVI decrease with the use of smaller delivery systems and experience and increase with high-risk scores (STS) and the presence of diabetes. In addition, VARC major vascular complications, observed mostly in patients with diabete mellitus (DM) and high STS scores, were associated with vascular diameters. These results further underline the importance of experience and a multidisciplinary team in patient selection and management for TAVI.

Effect of coronary artery bypass surgery on left ventricular function as assessed by strain and strain rate imaging

INTRODUCTION

This study examined the effect of coronary artery revascularization on left ventricular function and the results of strain imaging for the detection of ischemia before and after coronary artery bypass graft (CABG) surgery.

MATERIAL AND METHODS

Sixty-eight patients with a history of coronary artery disease (CAD) were included, prospectively. Conventional echocardiography and color tissue Doppler-derived strain-strain rate echocardiographic imaging were performed 24 hours before and 3 months after CABG surgery.

RESULTS

While strain rate values of the basal septum, middle segment of the lateral wall, middle segment of the inferior wall, and middle and basal segments of the anterior wall were significantly increased, other segments did not change after the operation. The mean systolic strain rate value was significantly increased after the operation. Left ventricle strain values in the middle segment of the septum, middle and basal segments of the inferior wall, and middle and basal segments of the anterior wall were significantly increased after the operation. No significant difference was noted in the basal septum or the middle and basal segments of the lateral wall after the operation. The mean systolic strain value was significantly increased after the operation.

CONCLUSION

The results of this study suggest that strain and strain rate echocardiography can provide an accurate evaluation of regional contractile function after CABG, even in the segments that are apparently normal.

Transfemoral balloon expandable aortic valve implantation in a patient with myelodysplastic syndrome

In this case presentation, the transcatheter aortic valve implantation (TAVI) intervention successfully performed on a 76-year-old male patient with severe degenerative aortic stenosis and diagnosed with myelodysplastic syndrome (MDS) is discussed. This case presentation represents the first case on the treatment of severe aortic stenosis on a patient with myelodysplastic syndrome through the use of the TAVI method and may form an alternative to surgery in patients with severe aortic stenosis who have a known haematological disease. For a successful procedure, the patient must be evaluated in cooperation with the haematology clinic and all necessary precautions regarding bleeding and infection complications of the patient must be taken prior to the procedure.

Early outcomes of carotid artery stenting

BACKGROUND AND AIM

Ischemic cerebrovascular events are the most common reason for patients to be bedridden and the third most common reason for death. Many studies in recent years have demonstrated that carotid artery stenting (CAS) may be an alternative to carotid endarterectomy (CEA). In this study, we aimed to report early outcomes of patients who were treated with CAS in our clinic and discuss practicability, advantages and safety of CAS.

METHODS AND FINDINGS

Eighty patients who underwent CAS between December 2009 and May 2011 were eligible. The mean age was 65 years (range, 49 - 89 years). Of the study group, 73.75% were males and 26.25% were female. The percentage of asymptomatic patients was 11.7%, and the remaining patients were symptomatic. A distal embolic protection device (Angioguard®) was used in 22% of the patients whereas, in the other patients (78%), a proximal blockage system (Mo.MA®) was used. Self-expandable hybrid stents were implanted in all patients and post-dilatation was performed after implantation. None of the patients suffered from stroke, myocardial infarction or death due to CAS during their hospital stay. The mean follow-up period was 10 months (range 2 - 18 months) after discharge. None of the patients had died or had a stroke, a transient ischemic attack (TIA), or a myocardial infarction during the follow-up period. Re-stenosis was not observed in the follow-up carotid Doppler ultrasonography; flow rates were within normal limits.

CONCLUSION

No major complication was observed during the early follow-up period in patients who underwent CAS in our clinic. Only 2 (2.5%) patients showed transient numbness and weakness and these did not lead to morbidity. In the management guide of extracranial carotid and vertebral artery diseases, CAS, in the light of recent studies, is recommended as an alternative to CEA in recommendations for revascularization. One of the important issues emphasized in this guide is the experience of centers. Very low complication rates after CAS suggested that, with suitable patient selection and an experienced team, similar results may be obtained.
