PURPOSE: Laparoscopy is widely used in many surgical areas for diagnosis and treatment. The need for sterilization of reusable instruments is an important issue. Ensuring patient safety, preventing infection, and protecting the functionality of the instruments are the most important points to be considered. We aimed to investigate two sterilization methods and their effects generated by their distribution into intra-abdominal tissues during insufflation. MATERIALS AND METHODS: 21 rats were used in the study...

BACKGROUND: Remote kidney damage is a sequel of hepatic ischemia-reperfusion (I/R) injury. Silibinin is the main ingredient of the milk thistle plant seed extract with known antioxidant and hepatoprotective activity. Our study investigates the nephroprotective potential of intravenously administered silibinin, as a lyophilized SLB-hydoxypropyl-beta-cyclodextrin product, in hepatic I/R injury. MATERIAL AND METHODS: 63 Wistar rats were divided into three groups: Sham (virtual intervention); Control (45 min ischemia and reperfusion); and Silibinin (200 μL intravenous silibinin administration after 45 min of ischemia)...

The purpose of this study was to evaluate a suitable animal model for the in vivo evaluation of patency and vascular tissue regeneration in small intestinal submucosa (SIS) vascular grafts for hemodialysis access. First, a 4-mm U-shaped SIS vascular graft was implanted between the internal carotid artery (CA) and the external jugular vein (JV) in five sheep and six swine. The U-shape grafts remained functional for 53 ± 4 days in sheep and 32 ± 2 days in swine. The sheep model presented exaggerated inflammation, so the swine model was selected for the in vivo study...

OBJECTIVE: To investigate the role of cordycepin in testicular ischemia/reperfusion injury in rats. MATERIALS AND METHODS: Forty Wistar albino rats were randomly divided into four groups, as follows: group one, control (C); group two, torsion and ischemia (I); group three: detorsion with ischemia-reperfusion (IR); and group four, detorsion/cordycepin. The rats were then analyzed macromorphologically and histopathologically, and blood tests were performed. Specifically, the total oxidant status (TOS) and total antioxidant status (TAS) were determined, and malondialdehyde (MDA), tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β levels were analyzed...

AIM: Acromioclavicular joint dislocation is one of the most common shoulder problems and may lead to instability or degenerative changes. The aim of this study was to compare the clinical outcomes of the Tight Rope system and clavicular hook plate for Rockwood type III acromioclavicular joint dislocation in adults. MATERIALS AND METHODS: This was a prospective, randomized study in a hospital setting. From January 2012 to December 2014, 69 patients with type III injury were reviewed...

PURPOSE: The aim of this study was to assess the effects three electrospun fiber membranes on postoperative adhesion formation in rat surgical models. MATERIALS AND METHODS: The PEG-PHBV (polyethylene glycol and poly-β-hydroxybutyrate valerate), PLA(Polylactic acid) and CS-PEG(chitosan and polyethylene glycol) were used for submicrometric membranes fabrication by electrospinning. A total of 64 SD male rats were randomly divided into 4 groups, one control group and 3 treatment groups, each consisting of 16 rats...

Laparoscopic gastric sleeve (LGS) resection in super-obese patients (BMI > 50 kg/m(2)) is a challenging procedure. We have developed a unique approach and technique for LGS with no buttress stapling and without oversewing. After 102 operations there have been no leaks and late complications.

BACKGROUND: Esmolol an ultrashort acting cardioselective β1-adrenergic receptor antagonist), has been successfully employed for perioperative sympatholysis. In this study, we tested the hypothesis that perioperative esmolol administration resulted in decreased postoperative pain and improves the hemodynamic balance in patients with rhinoplasty. METHODS: In this clinical trial study, fifty-six patients (56) undergoing rhinoplasty surgery were randomly distributed into two groups (Group E and Group C)...

PURPOSE: To evaluate long-term functional outcomes of Internal Delorme's Procedure (IDP) in patients refractory to conservative treatment for Obstructed Defecation Syndrome (ODS), and to compare those who received postoperative rehabilitation with those who did not. MATERIALS AND METHODS: All patients with ODS refractory to nonoperative therapy were identified across three regional pelvic floor referral hospitals, and IDP was performed. Postoperatively selected patients received biofeedback therapy...

Primary hyperparathyroidism (PHPT) is defined by inappropriate elevation of parathormone, caused by parathyroid hyperplasia, also known as multi-gland disease (MGD), parathyroid adenoma (PA), or parathyroid carcinoma (PC). Although several studies have already been conducted, there is a lack of a definite diagnostic marker, which could unambiguously distinguish MGD from PA or PC. The accurate and prompt diagnosis has the key meaning for effective treatment and follow-up. This review paper presents the role of apoptosis in PHPT...

BACKGROUND: Previous studies suggest that intestinal epithelial stem cells (IESC), critical drivers of homeostasis and regeneration, include two subpopulations: crypt-based columnar and "position +4" stem cells, identified by Lgr5 and Bmi1 biomarkers, respectively. Teduglutide is an enterotrophic counterpart of glucagon-like peptide 2. This study aimed to investigate the response of putative IESC to surgical injury and teduglutide administration on an animal model of intestinal resection and anastomosis...

INTRODUCTION: The implementation of enhanced recovery programmes after elective colorectal surgery has dramatically reduced the length of stay. The objective of this study was to assess the selection of good candidates for short post-operative stay (GCSS) in the context of stoma closure. METHODS: Between January 2011 and December 2014, 222 patients were included in the present retrospective, single-center study. The primary endpoint was the proportion of GCSS. We also identified factors associated with GCSS status and built a predictive score...

OBJECTIVE: Oxidative stress is one of the major causes of methotrexate induced lung injury (MILI). Alpha-lipoic acid (ALA), which occurs naturally in human food, has antioxidative and anti-inflammatory activities. The aim of this study was to research the potential protective role of ALA on MILI in rats. METHODS: Twenty one rats were randomly subdivided into three groups: control (group I), methotrexate (MTX) treated (group II), and MTX+ALA treated (group III). Lung injury was performed with a single dose of MTX (20 mg/kg) to groups 2 and 3...

PURPOSE: Lung ischemia-reperfusion injury (LIRI) can complicate lung transplantation or cardiac surgery with cardiopulmonary bypass, increasing morbidity and mortality. In LIRI, pro-inflammatory cytokines are activated, reactive oxygen species are generated and nuclear factor-κB (NF-κB) is up-regulated, altering lung mechanics. We tested the effect of the flavonoid apigenin on a rodent model of LIRI. METHODS: Thirty-seven Wistar rats were subjected to LIRI with or without a single or double dose of apigenin...

Purpose/Aim of the study: We investigated the effects of different positive end-expiratory pressure (PEEP) levels on postoperative respiration parameters in patients undergoing laparoscopic cholecystectomy. MATERIALS AND METHODS: One hundred and five consecutive patients were randomly divided to three groups (n = 35, for each group). Group I did not receive PEEP whereas group II received PEEP as 5 cmH2O and group III received PEEP as 8 cm H2O. Measurements with spirometer were taken 1 hour before the operation (T1) and, 1 (T2), 6 (T3), and 24 hours (T4) after extubation by an anesthetist...

AIMS: Varicocelectomy is the most common operation carried out by doctors for male infertility treatment. The aim of varicocele treatment is to hinder the refluxing venous drainage to the testis, retaining arterial inflow, and lymphatic drainage. A lot of pain is generated after this surgery, and the use of opium should be reduced to nearest minimum, as all drugs are toxins. Thus the aim of the present study is to facilitate morphine usage reduction after varicocelectomy surgery. MATERIAL AND METHODS: One-hundred (100) patients who were varicocelectomy candidate were randomized into two groups: experimental group contain 50 patients and control group contain 50 patients as well...
