Interest has grown in reducing the size of laparoscopic instruments. We define as "needlescopic" those instruments that have a diameter of < or =3 mm. We compared data from 60 needlescopic cholecystectomies with a matched group of laparoscopic procedures. No intraoperative complications occurred in either group. Operative time was 20% longer for the(More)
UNLABELLED Although the role of laparoscopic techniques in performing major colorectal resections is unclear, laparoscopy may be well suited for fecal diversion procedures because no resection and minimal tissue dissection is required. PURPOSE This report reviews our initial experience with laparoscopic stoma procedures to assess safety and efficacy. (More)
Background: Because of the inability to palpate colonic tumors during laparoscopy, their location must be precisely identified before resection is undertaken. Method: A retrospective study was performed of 58 patients in order to be able to describe our methods of tumor localization for laparoscopic colorectal operations and to review their effectiveness.(More)
BACKGROUND The fervor surrounding minimally invasive surgery, which began with laparoscopic cholecystectomy in the late 1980s, has spread to nearly all surgical specialties. METHODS After experimental success in an animal model, we recently performed our first case of endoscopic subtotal parathyroidectomy in a 37-year-old man. The patient, who had a(More)
PURPOSE This study was undertaken to describe our results in a series of patients undergoing total abdominal colectomy with ileorectal anastomosis (TAC/IRA) using laparoscopic techniques in patients with familial adenomatous polyposis (FAP) and rectal-sparing. Young patients with FAP requiring TAC/IRA may be ideal candidates for minimally invasive surgery,(More)
Ventral hernia repair is one of the most common abdominal operations. Recurrence rate remains high despite all preventive measures. "Tension-free" repair has been postulated as the surgical method of choice. A laparoscopic approach to ventral hernia repair has been described recently. Theoretical advantages of a laparoscopic repair include faster recovery,(More)
Laparoscopic antireflux surgery has become the standard operation for gastroesophageal reflux disease (GERD). This study examined the outcomes of laparoscopic antireflux surgery, hypothesizing that both subjective symptoms and objective pH would correlate with manometric parameters to reflect the absence of reflux after fundoplication. We evaluated 56(More)
OBJECTIVES Endoscopically sutured vascular anastomoses are complex, time consuming, and require great dexterity. We decided to evaluate performance enhancement using a robotic device to create sutured coronary artery bypass anastomoses with endoscopic techniques in a plastic model. METHODS Seven coronary artery bypass anastomoses were endoscopically(More)
Background: Some of the persistent problems associated with laparoscopic surgery stem from the inability of the surgeon to palpate the abdominal contents during the operation. This lack of tactile sensation can lead to poor abdominal exploration, difficulty in extracting the organs, and a relatively long operation time compared to conventional procedures.(More)
OBJECTIVE To evaluate the feasibility, safety, and sterility issues with regard to the use of a robotic device to perform uterine horn anastomosis in a live porcine model. DESIGN Prospective animal study. SETTING Landrace-Yorkshire pigs in a conventional laboratory setting. INTERVENTION(S) Six female pigs underwent laparoscopic bipolar(More)
