[show abstract][hide abstract] ABSTRACT: Various techniques of laparoscopic Roux-en-Y gastric bypass have been described. We completely standardized this procedure to minimize its sometimes substantial morbidity and mortality. This study describes our experience with the standardized fully stapled laparoscopic Roux-en-Y gastric bypass (FS-LRYGB) and its influence on the 30-day morbidity and mortality.
We retrospectively analyzed 2,645 patients who underwent FS-LRYGB from May 2004 to August 2008. Operative time, hospital stay and readmission, re-operation, and 30-day morbidity/mortality rates were then calculated. The 30-day follow-up data were complete for 2,606 patients (98.5%).
There were 539 male and 2,067 female patients. Mean age was 39.2 years (range 14-73), mean BMI 41.44 kg/m(2) (range, 23-75.5). The mean hospital stay was 3.35 days (range 2-71). Mean total operative time was 63 min (range 35-150). One patient died of pneumonia within 30 days of surgery (0.04%). One hundred and fifty one (5.8%) patients had postoperative complications as follows: gastrointestinal hemorrhage (n = 89, 3.42%), intestinal obstruction (n = 9, 0.35%), anastomotic leak (n = 5, 0.19%) and others (n = 47, 1.80%). In 66 patients, the bleeding resolved without any surgical re-intervention. One hemorrhage resulted in hypovolemic shock with subsequent renal and hepatic failure.
The systematic approach and the full standardization of the FS-LRYGB procedure contribute highly to the very low mortality and the low morbidity rates in our institution. Gastrointestinal bleeding appears to be the commonest complication, but is self-limiting in the majority of cases. Our approach also significantly reduces operative time and turns the technically demanding laparoscopic Roux-en-Y gastric bypass procedure into an easy reproducible operation, effective for training.

[show abstract][hide abstract] ABSTRACT: Venous insufficiency of the lower extremities is a highly prevalent condition. Successful treatment of superficial venous insufficiency will most often necessitate treatment of the saphenofemoral junction incompetence with correction of saphenous vein reflux. In the majority of patients it concerns a reflux of the greater saphenous vein. The standard procedure consists of ligation and stripping of the greater saphenous vein combined with with additional phlebectomies or ligation of insufficient perforant veins if necessary. Although the standard procedure is widely known and accepted, the postoperative morbidity and postoperative limitations of activity are high. In this context minimally invasive percutaneous endovenous techniques were developed to improve the patients comfort and faster resumption of work. Among these, endovenous laser ablation of the greater saphenous vein is a relatively new procedure. Percutaneous introduction of a laser fiber into the incompetent vein and ablation with pulsed laser energy is far less invasive than stripping.
