IntroductionMultiple suture techniques and various mesh repairs are used in open or laparoscopic umbilical hernia (UH) surgery.AimTo compare long-term follow-up results of UH repair in different hernia surgery groups and to identify risk factors for UH recurrence.Material and methodsA retrospective analysis of 216 patients who underwent elective surgery for UH during a 10-year period was performed. The patients were divided into three groups according to surgery technique (suture, mesh and laparoscopic repair). Early and long-term follow-up results including hospital stay, postoperative general and wound complications, recurrence rate and postoperative patient complaints were reviewed. Risk factors for recurrence were also analyzed.ResultsOne hundred and forty-six patients were operated on using suture repair, 52 using open mesh and 18 using laparoscopic repair technique. 77.8% of patients underwent long-term follow-up. The postoperative wound complication rate and long-term postoperative complaints were significantly higher in the open mesh repair group. The overall hernia recurrence rate was 13.1%. Only 2 (1.7%) patients with small hernias (< 2 cm) had a recurrence in the suture repair group. Logistic regression analysis showed that body mass index (BMI) > 30 kg/m2, diabetes and wound infection were independent risk factors for umbilical hernia recurrence.ConclusionsThe overall umbilical hernia recurrence rate was 13.1%. Body mass index > 30 kg/m2, diabetes and wound infection were independent risk factors for UH recurrence. According to our study results, laparoscopic medium and large umbilical hernia repair has slight advantages over open mesh repair concerning early postoperative complications, long-term postoperative pain and recurrence.

IntroductionLaparoscopic appendectomy is a well-described surgical technique and has gained wide clinical acceptance. Laparoscopic appendectomy offers fewer wound infections, faster recovery and an earlier return to work in comparison to open surgery. However, concerns still exist regarding the appendiceal stump closure.AimThe aim of this study was to compare the overall incidence and specific intraoperative and postoperative complications after application of intracorporeal knotting with invaginating suture versus endoloops for stump closure in laparoscopic appendectomy.Material and methodsOne hundred fifty two consecutive patients according to the following inclusion criteria were included in the study: 1. Laparoscopic appendectomy was performed during the study period; 2. Acute phlegmonous or gangrenous appendicitis without perforation was diagnosed during operation. Exclusion criteria - patients with acute perforated appendicitis and local or diffuse peritonitis. Data was grouped according to the appendiceal stump closure technique, with either endoloops – 112 patients (73.7 percent) or intracorporeal knotting with invaginating suture – 40 patients (26.3 per cent). The primary outcome measure was the rate of intraabdominal surgical-site infection, defined as post-operative intra-abdominal abscess. Secondary outcome variables were intraoperative and postoperative complications, duration of operation, hospital stay.ResultsThere were no significant differences between the two groups in overall intraoperative and postoperative complications rate and in hospital stay. The median duration of operation was significantly shorter when the endoloop was used. The use of intracorporeal knotting with invaginating suture instead of endoloop to close the appendiceal stump decreased the total cost of laparoscopic appendectomy.ConclusionsAccording our study results, intracorporeal knotting with invaginating suture appendiceal stump closure technique is acceptable laparoscopic procedure, which intraoperative and postoperative results do not differ from endoloops technique. The total cost of this procedure is 80 € cheaper then endoloops technique.

BackgroundRecent data shows that patients with severe acute pancreatic might benefit from early intensive therapy, enteral nutrition and timely transfer to specialized centers. The early prophylactic use of antibiotics in AP remains controversial. The role and need for new markers in stratification of acute pancreatitis is also uncertain. This study aims to evaluate the prognostic usefulness of adipokines in prediction of the severity and outcome of acute pancreatitis (AP).MethodsProspective study was conducted in four clinical centers. The diagnosis and severity assessment of AP was established according to the revised 2012 Atlanta classification. Adipokines, IL-6 and CRP levels were measured at admission and on 3rd day of hospital stay and compared with the control group. The predictive accuracy of each marker was measured by area under the receiver operating curve.ResultsForty healthy controls and 102 patients were enrolled in to the study. Twenty seven (26.5 %) patients had mild, 55 (53.9 %) - moderate and 20 (19.6 %) - severe AP. Only resistin (cut-off value 13.7 ng/ml) and IL-6 (cut-off value 473.4 pg/ml) were reliable early markers of SAP. IL-6 with cut-off value of 157.0 pg/ml was a predictor of necrosis. The peripancreatic necrosis volume of 112.5 ml was a marker of SAP and 433.0 ml cut-off value could be used to predict the need of interventions.ConclusionsThe prognostic value of adipokines in AP is limited. Only admission resistin levels could serve as an early predictor for SAP.The Lithuanian Regional Ethics Committee approved the study protocol (permission No. L-12-02/1/2/3/4) and all the patients and the control group provided written informed consent.

Diagnosis of EXPN and recognition of non-homogeneous collections show only fair agreement potentially resulting in inconsistent reporting of morphologic findings.

Deregulated microRNA (miRNA) expression profiles and their contribution to carcinogenesis have been observed in virtually all types of human cancer. However, their role in the pathogenesis of rare mesenchymal gastrointestinal stromal tumors (GISTs) is not well defined, yet. In this study, we aimed to investigate the role of two miRNAs strongly downregulated in GIST—miR-375-3p and miR-200b-3p—in the pathogenesis of GIST. To achieve this, miRNA mimics were transfected into GIST-T1 cells and changes in the potential target gene mRNA and protein expression, as well as alterations in cell viability, migration, apoptotic cell counts and direct miRNA–target interaction, were evaluated. Results revealed that overexpression of miR-375-3p downregulated the expression of KIT mRNA and protein by direct binding to KIT 3′UTR, reduced GIST cell viability and migration rates. MiR-200b-3p lowered expression of ETV1 protein, directly targeted and lowered expression of EGFR mRNA and protein, and negatively affected cell migration rates. To conclude, the present study identified that miR-375-3p and miR-200b-3p have a tumor-suppressive role in GIST.
