Surgeon performed continuous intraoperative ultrasound guidance decreases re-excisions and mastectomy rates in breast cancer.

Background: Intraoperative ultrasound guided (IUG) breast conserving surgery (BCS) is being increasingly embraced by breast surgeons worldwide. We aimed to compare the efficacy of IUG-BCS for palpable and nonpalpable breast cancer with respect to margin status, re-excision rate, tissue sacrifice and cost-time analysis.

Methods: Intraoperative localization protocol includes intraoperative ultrasound prior to excision to localize the lesion and guide the initial resection.

N-acetyl-cysteine improves anastomotic wound healing after radiotherapy in rats.

Aim: This study was designed to determine the effects of intraperitoneally or orally administered N-acetylcysteine (NAC) on anastomotic healing of irradiated rats.

Methods: Thirty-two male Wistar albino rats were randomized into four groups containing 8 rats each: I; standard resection plus anastomosis, II; radiation plus standard resection plus anastomosis, III; radiation plus standard resection plus anastomosis plus oral NAC, IV; radiation plus standard resection plus anastomosis plus intraperitoneal NAC. Four types of assessment were performed: bursting pressure, hydroxiproline (OHP) content, histopathology, and biochemical evaluation, including serum malondialdehyde (MDA), advanced oxidation protein products (AOPP), reduced glutathione (GSH) and superoxide dismutase (SOD) activities.

Background: The aim of this study was to investigate whether intraabdominal Ankaferd Blood Stopper (ABS) causes increased intraabdominal adhesion formation and to determine any side effects of ABS in vivo.

Methods: The present experimental study was designed to examine the effects of Ankaferd solution on peritoneal adhesion formation in a rat model of cecal abrasion. Intraperitoneal adhesions were assessed macroscopically and histopathologically on the 10th postoperative day.

Bacterial translocation in experimental stroke: what happens to the gut barrier?

The reasons of post-stroke infections are still incompletely understood. Bacterial translocation (BT), the passage of viable microbes across an even anatomically intact intestinal barrier, has been described in many critical illnesses. To date, it has not been studied as a source of infection in an animal stroke model.

Mitigation of indomethacin-induced gastric mucosal lesions by a potent specific type V phosphodiesterase inhibitor.

Aim: To investigate the gastroprotective effect of vardenafil against indomethacin-induced gastric damage.

Methods: Forty-eight female Wistar albino rats were randomly divided into 6 groups. Group 1 received saline only.

Evaluation of a new hemostatic agent Ankaferd Blood Stopper in experimental liver laceration.

Introduction: Hemorrhage is a leading cause of death after trauma. It is also the major cause of operating room deaths among patients who undergo liver surgery. Various techniques and materials have been attempted to manage bleeding, but a standard method has not been defined yet.

Effect of 2-octyl-cyanoacrylate on ischemic anastomosis of the left colon.

Introduction: 2-octyl-cyanoacrylate may be a good alternative in ischemic colon anastomosis without impairment of tissue perfusion.

Methods: Forty male Wistar albino rats were randomized into four experimental groups (n = 10 in each group). In group 1 (control), a well-perfused left colonic segment was transected, and free ends were anastomosed by propylene sutures.

Erythropoietin: a possible cytoprotective cytokine in acute necrotizing pancreatitis.

Background/purpose: Despite decades of research and clinical trials, a specific therapeutic treatment for acute pancreatitis (AP) has yet to be developed. The aim of the present study was to investigate the effects of erythropoietin on the severity of taurocolic acid-induced acute necrotizing pancreatitis.

Methods: Forty-seven male Wistar albino rats were randomized into seven experimental groups.

Complications of total thyroidectomy performed by surgical residents versus specialist surgeons.

Purpose: Surgeon inexperience has been defined as a significant predictor of deleterious outcome in thyroid surgery; however, the safety of training programs in which residents are the primary surgeons is controversial. The objective of this prospective study was to compare the complication rates of total thyroidectomy (TT) performed by residents with those of TT performed by specialist surgeons in similar patient groups.

Methods: Between April 2001 and May 2007, 144 patients underwent TT at our hospital.

Appendiceal mucocele: case reports and review of current literature.

The mucocele of the appendix is an uncommon disorder which is often asymptomatic but sometimes causes acute appendicitis-like symptoms. Sometimes, patients with mucocele can present with confusing symptoms. Preoperative suspicion and diagnosis of appendiceal mucocele are important.

Protective effects of erythropoietin against acute lung injury in a rat model of acute necrotizing pancreatitis.

Aim: To investigate the effect of exogenous erythro-poietin (EPO) administration on acute lung injury (ALI) in an experimental model of sodium taurodeoxycholate- induced acute necrotizing pancreatitis (ANP).

Methods: Forty-seven male Wistar albino rats were randomly divided into 7 groups: sham group (n = 5), 3 ANP groups (n = 7 each) and 3 EPO groups (n = 7 each). ANP was induced by retrograde infusion of 5% sodium taurodeoxycholate into the common bile duct.

The effect of sildenafil on an animal model for ischemic colitis.

Introduction: Sildenafil both enhances vasodilatation by relaxing the smooth muscle in the vessels and inhibits platelet aggregation. We have therefore examined the potential benefits of sildenafil on an animal model for ischemic colitis (IC).

Methods: Twenty-eight female Wistar albino rats weighing 250-300 g were randomized into three experimental groups as follows: in Group 1, animals were sham operated (n = 8) and received tap water; in Groups 2 and 3, the rats underwent a standardized surgical procedure to induce IC (n = 10 in each group).

The Janeway gastrostomy tube for recurrent gastric intubations: a novel and simple animal model.

Access to the gastric lumen can be achieved by different methods. Orogastric tubes and tube gastrostomies are frequently used but these routes have some disadvantages when recurrent gastric intubations or infusions are concerned. The Janeway gastrostomy tube is a simple-to-perform procedure and can serve as an excellent way to reach the gastric lumen of animals.
