Background: Short-term benefits of laparoscopic relative to conventional colorectal resections have been demonstrated in randomized controlled trials. It has been suggested that a diminished cytokine and acute-phase response may be responsible for these advantages. Methods: In a randomized controlled trial, patients underwent laparoscopic (n=30) or(More)
Loss of pancreatic beta cells is the crucial event in the development of type 1 diabetes. It is the result of an imbalance between autoimmune destruction and insufficient regeneration of islet cells. To study the role of islet cell regeneration in the pathogenesis of type 1 diabetes, we focused on PAX4, a paired homeodomain transcriptional repressor that is(More)
Background: Conventional colorectal resections are associated with severe postoperative pain and prolonged fatigue. The laparoscopic approach to colorectal tumors may result in less pain as well as less fatigue, and may improve postoperative recovery after colorectal resections. Methods: Sixty patients were included into a prospective randomized trial to(More)
This study reviews the recent overall experience in one colorectal surgery department with congenital presacral tumors in adults. 24 patients greater than 21 years of age, who underwent curative resection between January 1980 and August 1992, were analyzed retrospectively. The growths were divided into two broad categories: developmental cysts and(More)
Background: A shorter duration of postoperative ileus and earlier oral alimentation of patients may be a clinically relevant benefit of laparoscopic compared with conventional colorectal resection. Patients/Methods: A total of 60 patients were randomised to either laparoscopic (n=30) or conventional (n=30) resection of colorectal tumours. Major endpoints(More)
Background: The size of laparoscopic instruments has been reduced for use in abdominal video endoscopic surgery. However, it has yet to be proven that microlaparoscopic surgery will actually result in clinically relevant benefits for patients. Methods: Fifty patients were randomized in a blinded fashion to receive either elective laparoscopic (MINI), (n=(More)
Background: The effects of laparotomy and laparoscopy with different gases on subcutaneous and intraperitoneal tumor growth have not been evaluated yet. Methods: Tumor growth of colon adenocarcinoma DHD/K12/TRb was measured in rats after laparotomy, laparoscopy with CO2 or air, and in control group. Cell kinetics were determined after incubation with carbon(More)
A 46-year-old Caucasian female underwent vaginal hysterectomy for myoma in another hospital and developed a high rectovaginal fistula 6 weeks later. A diverting-loop colostomy of the sigmoid colon was performed 2 months later. The patient was admitted to our service with persistent high rectovaginal fistula 6 months later. We resected the sigmoid colon and(More)
Most trocars currently used to place a cannula through the abdominal wall have a conical or pyramidal tip. Because the risk of inadvertent injury along with removal of the cannula is probably related to (a) the force needed to traverse the abdominal wall, (b) the force needed to remove the trocar, and (c) the defect in the abdominal wall, the optimum(More)
Background: Laparoscopy is increasingly used in patients with intraabdominal bacterial infection although pneumoperitoneum may increase bacteremia by elevated intraabdominal pressure. Methods: The influence of laparotomy and laparoscopy on bacteremia, endotoxemia, and postoperative abscess formation was investigated in a rat model. Rats received(More)
