Alternative hepatic arterial reconstruction technique in case of total pancreaticoduodenectomy after celiac artery resection in pancreas cancer: Iliac-hepatic bypass.

Surgery is the only treatment method in pancreatic cancer. Unfortunately, metastatic diseases or invasion of the main vascular structures are observed in a majority of cases at the time of diagnosis; these structures originate from the body, neck, and tail of the pancreas and are considered inoperable. The first celiac artery resection for the treatment of cancer was described by Appleby in 1953.

An Alternative Technique in the Control of Massive Presacral Rectal Bleeding: Fixation of GORE-TEX Aortic Patch.

The presacral venous system is located under the pelvic fascia covering the anterior of the sacrum and consists of two lateral sacral veins, middle sacral vein, and the veins that communicate them. The presacral venous system can be easily damaged and causes serious bleeding which is difficult to control and may cause intraoperative mortality. Its incidence varies between 3% and 9.

A successful healthy live birth from a female patient with hypogonadotropic hypogonadism and oocytes with unusually large cytoplasmic inclusions.

This study aimed to report the case of a successful live birth from a woman having oocytes with abnormally large cytoplasmic inclusions. The patient described in this case is a 28 year-old woman with hypogonadotropic hypogonadism (HH) with a history of two previous unsuccessful in vitro fertilization (IVF) attempts offered an antagonist protocol. Stimulation was performed with human menopausal gonadotropin 300 IU/day.

Demographic characteristics and seasonal variations of acute appendicitis.

Background: The most common disease required emergency surgical operation is acute appendicitis. Appendectomy is the most common surgical procedure in the world and remains important due to be an efficient treatment method. We aimed to determine seasonal variations of acute appendicitis in our regions and identify the demographical and regional differences.

A rare condition: Ectopic liver tissue with its unique blood supply encountered during laparoscopic cholecystectomy.

Laparoscopy can aggravate the severity of pancreatitis in an experimental rat model.

Purpose: Over the past decade, laparoscopic techniques have markedly evolved, and it has been shown that minimally invasive surgery can provide a safe, effective, and less traumatic management of various surgical diseases. Additionally, it is well known that pancreatitis itself also produced severe oxidative tissue injury by increasing levels of reactive oxygen species. This study therefore aimed to investigate the effects of pneumoperitoneum on the severity of pancreatitis in a rat model of acute pancreatitis induced by cerulein.

Laparoscopic preconditioning protects against oxidative injury in cerulein-induced pancreatitis rats (an experimental study).

Background: Laparoscopic cholecystectomy, particularly in the same hospital stay, has been widely recommended to treat gallstone-pancreatitis over the last decade. Although pancreatitis produces severe oxidative injury, laparoscopy exerts an additional effect over that is produced by pancreatitis. The preconditioning phenomenon previously reported as protective in open surgery is a beneficial maneuver also in laparoscopic surgery.

The comparative effects of pneumoperitoneum on apoptosis and p53 expression in gastrointestinal organs.

Background: Laparoscopic surgical techniques have been increasingly preferred to classic laparotomy by surgeons since 1987. The pneumoperitoneum is often used to facilitate the intra-abdominal field, but it carries the risk of its ischemic potential and has differences [l2]of metabolic, inflammatory, and infectious consequences, depending on the pressure set and kind of gas used. However, the mechanisms related with the cell injury observed after laparoscopy are still unknown.

Efficacy of thoracic epidural analgesia for laparoscopic cholecystectomy.

Introduction: Postoperative pain is a commonly observed phenomenon after laparoscopic procedures. The use of new low-solubility inhalation anaesthetics leads to faster induction and recovery, but the effect of analgesics on pain when used with them is not sufficiently known. Optimally, analgesic therapy should be started in sufficient time as to be effective at the point of emergence from anaesthesia.

Stepwise rising CO2 insufflation as an ischemic preconditioning method.

Background: The pneumoperitoneum (Pp) is associated with ischemia and reperfusion (I/R) injury and oxidative stress. Various ischemic-preconditioning (IP) methods were used to reduce ischemic injury in intra-abdominal organs. In this experimental, randomized, controlled trial with a blind assessment of the outcome, we evaluated the effects of a new IP method, stepwise rising CO(2) insufflation, on oxidative stress and inflammatory cytokine response.

p53 Expression and apoptosis in liver and spleen during CO2 pneumoperitoneum.

Backgrounds And Aims: Laparoscopic surgery techniques have been increasingly preferred to classic laparotomy by surgeons since 1987. However, this method has some important adverse effects on intra-abdominal organs. The aim of this study is to evaluate the effects of different pressures of CO(2) on apoptosis and p53 expression in cells in liver and spleen.

The effects of CO2 pneumoperitoneum on the apoptotic index in the peritoneum.

During laparoscopic surgery, gases such as carbon dioxide (CO(2)), helium, or normal air are insufflated into the intra-abdominal cavity so the surgeon can obtain a clear surgical field; however, this insufflation technique may cause injury to the intra-abdominal organs. This study was undertaken to evaluate the effects of different pressures of CO(2) on the apoptotic index in the peritoneum during laparoscopic surgery. A total of 30 Sprague-Dawley male rats were used in the study.
