    Effects of caffeic acid phenethyl ester (CAPE) on sepsis in rats
    (SPRINGER/PLENUM PUBLISHERS, 2008) Tekin, Ahmet; Kuecuekkartallar, Tevfik; Tuerkyilmaz, Serdar; Dinckan, Ayhan; Esen, Hasan; Ates, Burhan; Yilmaz, Hueseyin
    Sepsis is still a major cause of the high mortality rate in the intensive care unit. Many studies have been published about the severity of sepsis, but the cause of mortality in sepsis and multiorgan failure is still obscure. This study investigated the effects of caffeic acid phenethyl ester (CAPE) particularly on the inflammatory and related histopathological changes in the lung, liver and kidney in an experimental sepsis model. Forty Sprague Dawley rats were used in this study, and were divided into four groups of ten rats each, as follows: Group I was given intraperitoneal saline infusion treatment. Group II was given intraperitoneal CAPE infusion treatment. Sepsis was induced in the animals in Group III (sepsis with saline infusion), while Group IV rats underwent induced sepsis plus CAPE infusion treatment (sepsis with CAPE infusion). Sampling was performed 48 h after treatment. The induction of sepsis resulted in a significant increase in serum glucose, leukocytes, urea, creatinine, LDH levels in BAL, plasma MDA, AST and ALT levels in the sepsis+saline group. The use of CAPE significantly decreased these parameters. Histopathological examination revealed less congestion, portal inflammation, and focal necrosis of the liver, and less congestion, edema, and emphysematous and inflammatory changes in the lung in the sepsis+CAPE group than in the other groups. These results support that CAPE may be used for the treatment of organ failure during sepsis.

    Effects of platelet rich plasma on colonic anastomosis
    (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008) Yol, Serdar; Tekin, Ahmet; Yilmaz, Hueseyin; Kuecuekkartallar, Tevfik; Esen, Hasan; Caglayan, Osman; Tatkan, Yueksel
    Purpose. To investigate the effect of platelet-rich plasma (PRP) on tissue maturation and wound healing in experimental colonic anastomosis. Materials and methods. Thirty Sprague Dawley rats were divided into three groups of 10 rats each. Group I (control group) was subjected to colon anastomosis only. Group II (PRP group) was subjected to colon anastomosis and topical PRP was applied. Group III (Bioglue group) was subjected to colon anastomosis and topical tissue sealant was applied (Bioglue; Cryo-life, Kennesaw, GA). The rats were sacrificed on postoperative day 7, and the bursting pressure of the anastomosis and tissue hydroxyproline levels were measured; histopathological changes on the anastomosis line were also examined. Results. The bursting pressure was statistically higher in the PRP group than in the control and Bioglue groups (P < 0.05). The hydroxyproline levels were also statistically higher in the PRP group than in the control and Bioglue groups (P < 0.05). Histopathologically, there was less inflammatory cell infiltration, intensive fibroblast development, and rich collagen production in the PRP group. Conclusion. PRP may be used in colon anastomosis, especially in patients with impaired wound healing, to obtain a better anastomotic strength. (c) 2008 Elsevier Inc. All rights reserved.

    Internal herniation as a major cause of intestinal obstruction
    (KARGER, 2008) Tekin, Ahmet; Kuecuekkartallar, Tevfik; Aksoy, Faruk; Vatansev, Celalettin; Belviranli, Metin; Tekin, Sakir; Yol, Serdar
    Objectives: To evaluate internal herniation as a rare cause of intestinal obstruction. Materials and Methods: Files of 18 cases, operated due to internal herniation between 2000 and 2006 at Selcuk University, Meram School of Medicine, General Surgery Department, were reviewed retrospectively. Sixteen patients (88.8%) were male (mean age: 58.2 years; range: 42-67) and 2 were female (mean age: 56.5 years; range: 52-61). Cases were grouped according to the location of internal herniation, and the clinical findings and applied treatment strategies were evaluated. Results: All patients were taken into surgical operation after preoperative preparations were completed. Findings were as follows: 6 cases of paraduodenal internal herniation, 4 of internal herniation through a defect in the terminal mesoileum, 2 of herniation through a defect in the falciform ligament, 2 of herniation through a defect in the omentum majus, 1 of herniation to the recessus over the bladder, 2 of herniation through a defect in the transverse mesocolon and 1 iatrogenically caused internal herniation through a defect in the mesojejunum. Conclusion: In an adult patient with findings of intestinal obstruction, diagnosis is difficult. Most cases presented to date are incidental findings during laparotomy, and surgical treatment is necessary. Copyright (c) c 2008 S. Karger AG, Basel.

    Use of chorioamniotic membrane instead of bogota bag in open abdomen: How I do It?
    (W J G PRESS, 2008) Tekin, Sakir; Tekin, Ahmet; Kuecuekkartallar, Tevfik; Cakir, Murat; Kartal, Adil
    It is one of the most important problems for general surgeons to decide which operation should be undertaken on patients with intra-abdominal infection, especially those with concomitant abdominal hypertension. Recentlly, closure techniques using prosthetic meshes in order to retain abdominal tension and to control sepsis have become very popular for patients with abdominal sepsis and hypertension. We used chorioamniotic membrane instead of plastic material to cover the open abdomen. We conclude that human chorioamniotic membrane prepared under sterile conditions may be an alternative to conventional plastic bags in daily practice, for preventing serosal erosion and fistulas in patients undergoing open abdominal surgery.
