Öğe The comparison of adhesion formation effects of HI-TEX®PARP NT and Proceed Mesh(Aves, 2008) Yalcin, Ercan; Hasdemir, Oguz; Buyukasik, Oktay; Dinler, Kahraman; Col, CavitPurpose: Aim of this experimental study is to compare the adhesion formation effects of two different prosthetic materials (HI-TEX (R) Parp NT mesh and Proceed mesh) in hernia repair. Material and Methods: Twenty Wistar-Albino rats were used for the study. Defects of 2x1 cm size were created at the right and left of each rat's anterior abdominal wall. Proceed mesh is implanted on the right side and HI-TEX mesh on the left side at half of them (Group A), and Proceed mesh is implanted on the left side and HI-TEX mesh on the right side at the other half (Group B) to repair the defect. Two rats of each group is sacrificed at the 7th, 14th, 21st, 28th and 35th days postoperatively and extension and severity of the adhesion and tissue reaction to the implants are evaluated. Results: At the end of the study, no difference was found between two groups concerning extension and severity of the adhesion. Adhesion were more frequent in the rats sacrificed on the 7th and 14th days. Proceed mesh adhesion extension (U=376, p < 0.05) and severity (U=352, p < 0.05)) were significantly less than HI-TEX mesh. Tissue reactions to implants were more with HI-TEX mesh, however, no difference was found statistically significant (x2=0.41, p > 0.05). Conclusion: We have the opinion that Proceed mesh is superior to HI-TEX mesh in hernia repair as it has less adhesion formation effect. As a result, Proceed mesh is thought to be a more suitable hernia repairment material compared to HI-TEX mesh.Öğe Gastric Volvulus Associated with Wandering Spleen in Adult: Case Report(Derman Medical Publ, 2012) Buyukasik, Oktay; Hasdemir, Ahmet Oguz; Kahramansoy, Nurettin; Col, Cavit; Erkol, HayriGastric volvulus associated with wandering spleen is a rare diagnosis in adult ages. So far, only two cases have been reported in the literature. 82 year old male patients admitted to emergency department with complaint of nausea, vomiting and constipation. Physical examination and computerize tomography detected a big solid mass with regular contour which is full filling abdominal left lower quadrant. Exploratory laparotomy revealed a wandering spleen in sizes of 13x13x15 cm in the mentioned region. The spleen which had two masses on was partially ischemic. The stomach had rotated through cardiopyloric axis due to long pedicle of the spleen and adhesions neighborhood to corpoantral junction. Thus gastric passage was partialy obstructed. Splenectomy and anterior gastropexy were applied. The patient was discharged in health at 6th day postoperatively.Öğe RANDOMIZED CLINICAL TRIAL OF STAPLED HEMORRHOIDOPEXY VERSUS FERGUSON HEMORRHOIDECTOMY(Yerkure Tanitim & Yayincilik Hizmetleri A S, 2008) Buyukasik, Oktay; Hasdemir, Ahmet Oguz; Keskin, A. Ilker; Arikan, Bilal; Bulbul, SalihObjective: The purpose of this study was to compare stapled hemorrhoidopexy (SH) with that of the Ferguson hemorrhoidectomy (FH) for the surgical treatment of hemorrhoidal disease. Material and Methods: Fifthy patients with grade III or IV haemorrhoids were randomized to undergo either the SH (n=25) or FH (n=25). Operative time, length of hospital stay, postoperative pain, early and late complications, time to return to normal daily activities ( both professional and social) and recurrence were evaluated. Follow up was one year. Results: Operative time, postoperative pain, the time to return to normal activities and recurrence were significantly less for patients in SH group. In the FH group early complications were more frequent but not statistically significant and there were no statistically significant differences regarding the frequency of late complications. Conclusion: Provided further clinical trials confirm these findings, SH may become a future gold standard.
