Systemic immune-inflammation index: A novel marker for predicting response to cardiac resynchronization therapy in patients with heart failure

Aim: To investigate the utility of systemic immune-inflammation index (SII) in predicting response to cardiac resynchronization therapy (CRT) among patients with heart failure (HF). Method: A total of 78 patients with HF who underwent CRT device implantation were included in this 6-month follow up study. Data on laboratory findings including complete blood count, blood biochemistry and SII as well as the transthoracic echocardiography findings were recorded at baseline prior to CRT device implantation and 6 months after CRT. Results: The criteria for response to CRT including improvements in New York Heart Association (NYHA), left ventricular end-systolic volume (LVESV) (decreased by ≥15%) and ejection fraction (EF) (increased by≥10%) were met by 73.1%, 65.4% and 69.2% of patients, respectively. In patients with decreased vs. increased SII values during 6-month therapy, the likelihood of meeting LVESV (84.3 vs. 15.7%, p<0.001), EF (81.5 vs. 18.5%, p<0.001) and NYHA (77.2 vs. 22.8%, p<0.001) response criteria for successful CRT were significantly higher. Multivariate analysis revealed that decrease in SII (OR 0.982, 95% CI: 0.970 to 0.995, p=0.006) and TAPSE (OR 0.602, 95% CI. 0.396 to 0.916, p=0.018) during treatment as the only significant determinants of presence of response to CRT in heart failure (HF) patients. Conclusions: Our findings seem to indicate the favorable utility of SII, as a non-invasive readily available marker, in predicting response to CRT and thus enabling a beneficial reverse remodeling process via timely implementation of advanced treatments in HF patients

Outcomes of elective liver surgery worldwide: a global, prospective, multicenter, cross-sectional study

Background: The outcomes of liver surgery worldwide remain unknown. The true population-based outcomes are likely different to those vastly reported that reflect the activity of highly specialized academic centers. The aim of this study was to measure the true worldwide practice of liver surgery and associated outcomes by recruiting from centers across the globe. The geographic distribution of liver surgery activity and complexity was also evaluated to further understand variations in outcomes. Methods: LiverGroup.org was an international, prospective, multicenter, cross-sectional study following the Global Surgery Collaborative Snapshot Research approach with a 3-month prospective, consecutive patient enrollment within January–December 2019. Each patient was followed up for 90 days postoperatively. All patients undergoing liver surgery at their respective centers were eligible for study inclusion. Basic demographics, patient and operation characteristics were collected. Morbidity was recorded according to the Clavien–Dindo Classification of Surgical Complications. Country-based and hospital-based data were collected, including the Human Development Index (HDI). (NCT03768141). Results: A total of 2159 patients were included from six continents. Surgery was performed for cancer in 1785 (83%) patients. Of all patients, 912 (42%) experienced a postoperative complication of any severity, while the major complication rate was 16% (341/2159). The overall 90-day mortality rate after liver surgery was 3.8% (82/2,159). The overall failure to rescue rate was 11% (82/ 722) ranging from 5 to 35% among the higher and lower HDI groups, respectively. Conclusions: This is the first to our knowledge global surgery study specifically designed and conducted for specialized liver surgery. The authors identified failure to rescue as a significant potentially modifiable factor for mortality after liver surgery, mostly related to lower Human Development Index countries. Members of the LiverGroup.org network could now work together to develop quality improvement collaboratives

Fully covered self-expandable metal stent for intraprocedural or late-diagnosed Type-II endoscopic retrograde cholangiopancreatography-related perforations

Background Perforations related to endoscopic retrograde cholangiopancreatography (ERCP) are rare but life-threatening complications. The treatment of Type-II-periampullary perforations that develop during endoscopic sphincterotomy remains a topic of discussion. This study aimed to evaluate the usefulness of fully covered self-expanding metal stenting (FCSEMS) for treating Type-II perforations. Methods The files of all patients who underwent the ERCP procedures between January 2015 and October 2021 were retrospectively reviewed; patients with Stapher Type-II perforation were included in the current study. Patients with FCSEMS were classified into two groups: those who underwent FCSEMS and those who were conventionally followed up. Moreover, patients with FCSEMS were classified into two subgroups: those who underwent simultaneous stenting and those who underwent late stenting. Mortality, surgical intervention, percutaneous drainage, length of hospital stay, and inflammatory markers were all compared between the groups. Results Of the 9253 patients undergoing ERCP during the study period, 28 patients (0.3%) were found to have Type-II perforation. The mean age of these patients was 67.7 +/- 3.9 years, and 15 patients were female. FCSEMS was performed on 19 patients, whereas 9 patients were on conventional follow-up. None of the patients developed mortality. In the conventional follow-up group, one patient required percutaneous drainage and one required surgical intervention. In contrast, none of the patients in the FCSEMS group required additional intervention. At a statistically significant level, the length of hospital stay was found to be shorter in the FCSEMS group. There was no difference in inflammatory markers between the two groups. In nine patients, FCSEMS was performed simultaneously, whereas, in ten patients, FCSEMS was performed later because they required a second intervention. These two subgroups did not differ in terms of outcomes. Conclusions FCSEMS is a safe and effective treatment modality for patients with Type-II perforation. Moreover, it can be safely used in patients whose perforations are diagnosed during the ERCP procedure and in patients whose diagnoses are made after the procedure

Isolated Late Recurrence of Renal Cell Carcinoma in the Inferior Vena Cava

WOS: 000279285900009Renal cell carcinoma is an urologic malignancy with poor prognosis. Local invasion and distant metastasis determine the prognosis of the disease. Dissemination to inferior vena cava via renal vein is seen in 4-10% of the patients. The role of radiotherapy and chemotherapy is limited, surgery is the only curative treatment option and patients with liver metastasis also benefit from surgery. In patients with vena cava trombosis, cavotomy and trombectomy should be done to prolong survival, if nodal or visseral metastasis is not present. Surgical procedure differs according to location of trombus in inferior vena cava. In our case report, a patient treated with right nephrectomy due to renal cell carcinoma 3 years ago who was re-operated for vena caval trombus is mentioned. Operation was done without using Pringle technique (clamping of hepatic pedicle) by mobilization of the liver with piggy back technique, and after cavotomy and trombus excision, defect in vena cava was reconstructed with PTFE prosthetic graft. Here, we report this case and discuss it in the light of current literature

Perceptions of porta-celiac vascular models for hepatic surgery and their use in residency training

GOKMEN, Figen/0000-0001-9635-6308WOS:000625906900002PubMed: 33677685Background Primary aspect of hepatic navigation surgery is the identification of source vascular details to preserve healthy liver which has a vascular anatomy quite challenging for the young surgeons. The purpose was to determine whether three-dimensional (3D) vascular pattern models of preoperative computed tomography (CT) images will assist resident-level trainees for hepatic surgery. Methods This study was based on the perception of residents who were presented with 5 different hepatic source vascular patterns and required to compare their perception level of CT, and 1:1 models in terms of importance of variability, differential of patterns and preoperative planning. Results All residents agree that models provided better understanding of vascular source and improved preplanning. Five stations provided qualitative assessment with results showing the usefulness of porta-celiac models when used as anatomical tools in preplanning (p = 0.04), simulation of interventional procedures (p = 0.02), surgical education (p = 0.01). None of the cases had scored less than 8.5. Responses related to understanding variations were significantly higher in the perception of the 3D model in all cases, furthermore 3D models were more useful for seniors in more complex cases 3 and 5. Some open-ended answers: "The 3D model can completely change the operation plan" One of the major factors for anatomical resection of liver transplantation is the positional relationship between the hepatic arteries and the portal veins. Conclusion The plastic-like material presenting the hepatic vascularity enables the visualization of the origin, pattern, shape, and angle of the branches with appropriate spatial perception thus making it well-structured

Solid pseudopapillary neoplasms of the pancreas: Case series with a review of the literature

Karaca, Can A/0000-0003-4930-6222WOS:000621603800013PubMed: 33626007Background/Aims: The solid pseudopapillary neoplasms are quite rare tumors of the pancreas, comprising roughly 1-2% of all pancreatic neoplasms. It has a low malignant potential and usually affects young females. Despite increasing number of articles in the last decade, there is still debate on the pathogenesis, malignant potential and optimal surgical strategy for the solid pseudopapillary neoplasms. Materials and Methods: Medical recordings of 326 patients who were operated due to pancreatic mass were retrospectively analyzed. Patient demographics, presenting symptoms, surgical and pathologic characteristics of the tumor, postsurgical course, long-term survival, and other relevant data were extracted from patients' charts. Results: Majority of the patients were female in consistency with the classic data in the literature. All the patients underwent curative intent resections. Tumors were commonly localized in the tail of the pancreas making distal pancreatectomy the most commonly performed surgical procedure. Mean tumor diameter was 5.8 centimeters with tumor sizes ranging from 1 to 19 cm. Conclusion: The solid pseudopapillary neoplasms of the pancreas is a rare tumor with low malignant potential, which is more common in females of reproductive age, with abdominal pain being their most common presentation. The short-term outcomes in patients following surgical R0 resection are excellent. However, proximal placement of the tumor and female gender may have slightly worse prognosis. We hope that our findings from a series of patients represent a contribution to the existing literature on SPN, and authors declare their willingness to provide further details for future meta-analyses
