    The Effect of Natrium Hyaluronate Applied Locally for Pelviureteral Anastomoses
    (INFORMA HEALTHCARE, 2013) Yurtcu, Muslim; Baba, Zeliha Fusun
    Objectives: This study aimed to investigate the effect of natrium hyaluronate (NH) on fibrous tissue formation and wound healing in experimental pelviureteral anastomosis (PUA). Materials and methods: Eighteen rabbits were divided equally into three groups: surgical (S), sham (Sh), and NH. A 1-cm length of the ureteropelvic segment was resected through a laparotomy incision and then anastomosis was performed. The rabbits were injected with saline (Sh group) and NH (NH group) into anastomoses lines after the surgical procedure. The S group did not receive any medication during their procedure. Intravenous pyelography was carried out on postoperative day 21. The rabbits were sacrificed and dissected under a dissecting microscope and examined for acute inflammation (AI), chronic inflammation (CI), granulation tissue amount (GTA), granulation tissue fibroblast maturation (GTFM), collagen deposition (CD), neovascularization (N), re-epithelialization (R), and peripheral tissue reaction (PTR) in the anastomosis lines 3 weeks later. Main findings: There were no significant differences in the GTFM scores in the S group compared with those in the NH group. In the NH group, N scores were higher than they were in the S group. Re-epithelialization in the NH group was higher than it was in the S group. Principle conclusions: NH did not decrease fibrosis, but increased important parameters in wound healing such as neovascularization and re-epithelialization in an experimental model of PUA in rabbits.

    The effects of early and late feeding on healing of esophageal anastomoses: An experimental study
    (ELSEVIER IRELAND LTD, 2011) Yurtcu, Muslim; Toy, Hatice; Arbag, Hamdi; Caglayan, Osman
    Objective: To investigate the effects of postoperative late and early feeding on the healing of experimental esophageal anastomosis (EA). Methods: Twelve New Zealand rabbits were divided equally into 2 groups: late feeding (LF) and early feeding (EF). A 1-cm-length of the cervical esophagus was resected through a cervical incision, and then anastomosis was performed. The LF group was fed parenterally for 6 days and orally (per oral route) after esophagography on postoperative day 7 as long as there was no esophageal leakage. The EF group was fed orally (per oral route) 24 h after esophageal repairs (ERs), and esophagography was carried out on postoperative day 7 to check the ERs. The rabbits were sacrificed to evaluate bursting pressure (BP), diameter of the esophageal lumen (DOTEL), tissue hydroxyproline (HP), and wound healing scores (WHSs) in the anastomosis lines 8 weeks later. Results: In the LF group, BP and DOTEL were significantly lower than they were in the EF group, and HP was significantly higher than it was in the EF group. WHSs in the LF group were not higher than they were in the EFgroup. Conclusions: Early feeding is superior after EA as shown by increased DOTEL and BP levels, but causes decreased HP levels.

    Effects of fasting and preoperative feeding in children
    (W J G PRESS, 2009) Yurtcu, Muslim; Gunel, Engin; Sahin, Tahir Kemal; Sivrikaya, Abdullah
    AIM: To investigate whether children should undergo surgery without a long period of fasting after feeding. METHODS: Eighty children with inguinoscrotal disorders (aged 1-10 years) were studied prospectively. They were divided into eight groups that each contained 10 children who were fed normal liquid food (NLF) and a high-calorie diet (HCD) 2, 3, 4 and 5 h before surgery, in two doses at 6-h intervals. NLF was given to four groups and HCD to the other four. In all groups, glucose, prealbumin and cortisol levels in the blood were measured twice: just after oral feeding and just before the operation. After the establishment of adequate anesthesia, gastric residue liquid was measured with a syringe. RESULTS: Blood glucose levels in all patients fed NLF and HCD were high, except in patients in, the HCD-4 group. There was no significant difference in the blood prealbumin levels. There was a significant increase in the blood cortisol levels in the NLF-2 (14.4 +/- 5.7), HCD-2 (13.2 +/- 6.0), NLF-3 (10.9 +/- 6.4), and HCD-5 (6.8 +/- 5.7) groups (P < 0.05). CONCLUSION: The stress of surgery may be tolerated by children when they are fed up to 2 h before elective surgery. (C) 2009 The WJG Press and Baishideng. All rights reserved.

    A Giant Recurrent Aneurysmal Bone Cyst of the Sacrum: Discussion of Total Resectability in a Pediatric Case
    (ORTADOGU AD PRES & PUBL CO, 2011) Ozdemir, H. Mustafa; Yurtcu, Muslim; Ogun, Tunc C.
    Aneurysmal bone cyst (ABC) is a locally agressive tumor-like lesion of the bone. Sacral location is rare. Currently recommended treatment for a benign ABC lesion is complete intralesional curettage with or without selective arterial embolization and attempt to salvage unilateral sacral 2-5 roots. A 14-year-old girl presented with severe pain and a large mass in her lower lumbosacral region. Imaging studies demonstrated a destructive lesion, arising from the second sacral vertebral level, extending posteriorly and bilaterally into the gluteal muscles, and anteriorly into the pelvis. Open biopsy established the diagnosis of ABC. Marginal extra-capsular resection via a combined anterior and posterior approach, and postoperative radiation therapy were performed. The patient was pain-free, and no evidence of local recurrence was detected at the 84-month follow up postoperatively. Marginal extra-capsular resection and adjuvant radiotherapy are thought to be effective for the treatment of this large ABC of the sacrum.

    Surgical management with or without a nasogastric tube in esophageal repairs
    (ELSEVIER IRELAND LTD, 2012) Yurtcu, Muslim; Toy, Hatice; Arbag, Hamdi; Caglayan, Osman
    Objective: The aim of the study was to compare surgical management with or without a nasogastric tube (NGT) to prevent anastomotic stricture that occurred following esophageal repairs (ERs). Methods: Twelve New Zealand rabbits were divided equally into 2 m: with a NGT (experimental group) and without a NGT (control group). A 1-cm-length of the cervical esophagus was resected through a cervical incision and then anastomosis was performed using the NGT and keeping it in place for 6 days in the experimental group. The same procedures were performed in the control group. Both groups were fed parenterally for 6 days and orally after esophagography on postoperative day 7 as long as there was no esophageal leakage. The rabbits were sacrificed to evaluate diameter of the esophageal lumen (DOTEL), bursting pressure (BP), tissue hydroxyproline (HP) and wound healing scores (WHSs) in the anastomosis lines 8 weeks later. Results: In the experimental group, DOTEL, BP, and HP were significantly lower than they were in the control group. WHSs in the experimental group were not higher than they were in the control group. Conclusions: Surgical management without a NGT is more effective than management with a NGT in ERs as shown by increased DOTEL, BP, and HP levels. (C) 2011 Elsevier Ireland Ltd. All rights reserved.
