    Can direct bilirubin-to-lymphocyte ratio predict surgery for pediatric adhesive small bowel obstruction?
    (Mexican Acad Surgery, 2024) Azizoglu, Mustafa; Arslan, Serkan; Kamci, Tahsin O.; Basuguy, Erol; Aydogdu, Bahattin; Karabel, Muesemma A.; Okur, Mehmet H.
    Objective: Estimating which patients might require surgical intervention is crucial. Patients with complete bowel obstructions exhibit disrupted enterohepatic cycles of bile and bacteremia due to bacterial translocation. The goal of this study was to develop a prediction index using laboratory inflammatorydatato identifypatients who mayneed surgery. Materials and methods: The patients were divided into two groups based on their management strategy: Non -operative management (Group 1) and surgical management (Group 2). Results: The indirect bilirubin, direct bilirubin, and total bilirubin were significantly higher in Group 2 than in Group 1 (p = 0.001, p < 0.001, and p < 0.001, respectively). The neutrophil-to-lymphocyte ratio (NLR), platelet-to-NLR (PNLR), and direct bilirubin-to-lymphocyte ratio (DBR) were significantly higher in Group 2 compared to Group 1 (p = 0.041, p = 0.020, and p < 0.001, respectively). In group 2, 78% have viable bowels. Resection was performed in 40% of cases, with 12% mortality and a 10 -day average hospital stay. DLR performs the best overall accuracy (72%), demonstrating a well-balanced sensitivity (62%) and specificity (81%). Conclusions: This study suggested that DBR is a more accurate predictive index for surgical intervention in pediatric adhesive small bowel obstruction patients compared to NLR and PNLR, providing valuable guidance for treatment strategies.

    Magnetic Compression Ostomy for Simple Tube Colostomy in Rats - Magnacolostomy
    (Wroclaw Medical Univ, 2012) Uygun, Ibrahim; Okur, Mehmet H.; Arayici, Yilmaz; Keles, Aysenur; Ozturk, Hayrettin; Otcu, Selcuk
    Background. Magnetic compression anastomoses (magnamosis) have been previously described for gastrointestinal, biliary, urinary, and vascular anastomoses. Objectives. Herein, the authors report the creation of a magnetic compression colostomy (magnacolostomy) using a simple technique in rats. Material and Methods Animals were randomized into two groups (n = 8, each): a magnetic colostomy (MC) group and a control surgical tube colostomy (SC) group. In the MC group, the first magnetic ball (3 mm) was rectally introduced into the rat colon. The second magnetic ball (4 mm) was placed subcutaneously into the left quadrant, and the two magnetic balls strongly coupled. On postoperative day 20 for the MC group and postoperative day 10 in the SC group, the rats were sacrificed and the colostomies evaluated macroscopically, histopathologically, and for mechanical burst testing. Results. From the macroscopic evaluation, two rats failed to form the colostomy canal due to colostomy catheter and magnetic ball removal. In the remaining rats, evidence of complications were not observed. Two rats in the MC group displayed mild adhesion and all rats in the SC group displayed moderate adhesion. No significant differences between the burst pressures were observed. However, a significant difference (p < 0.001) between the procedure times of the MC (4.13 +/- 1.00 minutes) and SC groups (14.25 +/- 2.05 minutes) was evident. Conclusions: Magnacolostomy is an easy and effective procedure in the rat model and presents a safe, minimally invasive alternative to current tube colostomy procedures such as antegrade continence enemas, percutaneous endoscopic, and colostomy/cecostomy in humans (Adv Clin Exp Med 2012, 21, 3, 301-305).
