Evaluation of IGL-1 preservation solution using an orthotopic liver transplantation model.

AIM: To compare, in a pig liver transplantation model, the protective effect of UW with that of IGL-1, a high-sodium preservation solution containing polyethylene glycol (PEG) as an oncotic supply. METHODS: All livers were harvested and grafted orthotopically according to standard techniques. The livers were washed out and preserved for 7 h in IGL-1 (n = 6) or in UW solution (n = 7) at 4 degree centigrade. In a sham group (n = 4), the livers underwent a 60-min warm ischemia at 37 degree centigrade. The hepatocellular injury was assessed in organ preservation solution washed out from the graft at the end of ischemic storage (before revascularization), and in serum 2 h after reperfusion and daily for up to 6 d. RESULTS: Livers preserved in IGL-1 solution released markedly less AST than that preserved in the UW solution before and after revascularization (P < 0.05). Besides, the activity of creatine kinase-BB, a marker of sinusoidal lining cells injury, was higher in the UW group than in the IGL-1 group (P < 0.05). Histological results showed less necrotic regions in livers preserved in IGL-1 solution; however, no difference was observed for inflammation. CONCLUSION: IGL-1 liquid effectively protects parenchymal and non-parenchymal cells against preservation-reperfusion injuries.

Combined vaginal and abdominal approach to sleeve gastrectomy for morbid obesity in women: a preliminary experience.

BACKGROUND: Natural orifice translumenal endoscopic surgery is an emerging surgical phenomenon. Although the development of "pure" natural orifice translumenal endoscopic surgical techniques in humans has been slowed by major technical hurdles, "hybrid" or combined variants have been increasingly reported. Laparoscopic sleeve gastrectomy (SG) is a commonly performed treatment of morbid obesity. We have developed a combined variant of SG for patients with morbid obesity. Our aim was to assess the feasibility and safety of such an approach, which could eventually reduce the postoperative pain, preserve the abdominal wall, and enhance cosmesis. METHODS: Combined, transvaginal and abdominal SG was attempted in 20 patients. The inclusion criteria were morbid obesity (body mass index <50 kg/m(2)), female gender, an absence of gynecologic disorders, and the absence of major previous abdominal surgery. The local ethical committee approved the present study. The technique was performed using a vaginal incision with 1 or 2 abdominal ports. RESULTS: The procedure was a success in 14 patients (70%). In 6 patients, conversion to a more conventional laparoscopic SG was required, with ≥ 1 abdominal ports added. The mean operative time was 116 minutes (range 54-231). The postoperative complication rate was 5% (1 patient developed pneumonia). No hemorrhage, surgical site infection, or fistula was encountered. The mean length of hospital stay was 72 hours (range 24-144). CONCLUSION: Our combined, transvaginal and abdominal variant of laparoscopic SG was sure and feasible in a small series of selected patients with morbid obesity.
