The laparoscopic approach promises to become the gold standard for the transabdominal management of full-thickness rectal prolapse. The aim of this study was to review our experience and to highlight the functional results achieved with this new technique. Forty-eight patients with full-thickness external prolapse underwent laparoscopic repair between(More)
BACKGROUND/AIMS The aim of this retrospective study was to report and quantify the immediate and 3-year complications after laparoscopic anti-reflux surgery in order to understand the mechanism. METHODOLOGY From 1992 to 1996, 1470 laparoscopic fundoplications were performed for symptomatic gastroesophageal reflux disease. Preoperative checkup included(More)
STUDY AIM The aim of this multicenter retrospective study was to evaluate the immediate and 2-year results of the laparoscopic fundoplication for gastroesophageal reflux disease (GERD). PATIENTS AND METHODS From 1992 to 1996, 1,470 laparoscopic fundoplications were performed for symptomatic GERD. Preoperative workup included upper GI tract endoscopy in(More)
BACKGROUND The aim of this study was to review our experience with laparoscopic sigmoid colectomy for diverticular disease. METHODS All patients presenting with acute or chronic diverticulitis, obstruction, abscess, or fistula were included. Symptomatic diverticular disease was the main surgical indication (95%). RESULTS Between March 1992 and August(More)
BACKGROUND: The purpose of this study was to evaluate the 5-year survival of 206 consecutive patients with left colon carcinoma operated with a laparoscopic procedure between March 1992 and December 2000. METHODS: Patients with obstructing or bulky cancers were excluded from this study. Tumor stage was defined according to the Dukes modified classification.(More)
Background: The aim of this retrospective study was to compare the results of Nissen, Nissen-Rossetti, and Toupet laparoscopic fundoplication in terms of gastroesophageal reflux disease (GERD). Methods: From 1992 to 1996, 1,470 laparoscopic fundoplications were performed using one of three procedures: Nissen (n= 655), Nissen-Rossetti (n= 423), and Toupet(More)
AIMS To describe and illustrate the main applications of phase-contrast flow quantification in cardiovascular imaging. CONCLUSION Phase-contrast velocimetry sequences provide an accurate, reliable, reproducible and non-invasive study of blood flow, information which is sometimes not available from other investigation methods. The haemodynamic information(More)
In Drosophila, the transcription factor Gcm/Glide plays a key role in cell fate determination and cellular differentiation. In light of its crucial biological impact, major efforts have been put for analyzing its properties as master regulator, from both structural and functional points of view. However, the lack of efficient antibodies specific to the(More)
Phase-Contrast (PC) velocimetry MRI is a useful modality to explore cardiovascular pathologies, but requires the automatic segmentation of vessels. In this paper, we evaluate the ability of region-based active contours to efficiently segment carotid vessels, compared to traditionnal edgebased active contours considered in related works. Experiments are(More)
Phase-Contrast (PC) velocimetry MRI is a useful modality to explore cardiovascular pathologies, but requires the automatic segmentation of vessels. Most existing segmentation approaches focus on the exploitation of anatomical information to guide algorithms, such as widely used active contours we consider in this paper, although acquisitions simultaneously(More)
