Smaller individual series on the outcome of laparoscopic hernioplasty techniques have been reported. This study reports on the complications of 3,229 laparoscopic hernia repairs performed by the authors in 2,559 patients. The TAPP (transabdominal preperitoneal) technique was the most frequently performed: 1,944 (60%). The totally preperitoneal technique was(More)
The incidence and reasons for early recurrences following laparoscopic hernioplasty have not been studied. Because the incidence is small and the follow up is short, a multi-institutional study was performed among the pioneers in the field. The incidence figures were obtained by survey of surgeons who had significant experience (over 100 cases) and kept(More)
Although the laparoscopic technique is a new approach to groin hernia, it is becoming more widely accepted as an alternative to traditional open techniques. This study is a preliminary review of complications and recurrences. A questionnaire specific for complications was sent to each investigator. From 12/89 to 4/93, 1,514 hernias were repaired; 119 (7.8%)(More)
Postgastric bypass noninsulinoma hyperinsulinemic pancreatogenous hypoglycemia defines a group of patients with postprandial neuroglycopenic symptoms similar to insulinoma but in many cases more severe. There are few reports of patients with this condition. We describe our surgical experience for the management of this rare condition. A retrospective study(More)
Pancreatic islet cell tumors represent a diverse group of neuroendocrine lesions. These tumors may be singular or multiple, benign or malignant, sporadic, or part of the constellation of multiple endocrine neoplasia type 1. Tumors such as insulinomas and gastrinomas produce gastrointestinal peptides that lead to diagnosis. Nonfunctioning lesions may be(More)
Laparoscopic hernia repair remains controversial, and its position in current hernia surgery remains in flux. In this article we attempt to put the laparoscopic approach in perspective by describing the rationale for its development. We summarize studies comparing it with open repairs, including recent publications, meta-analyses, and systematic reviews;(More)
Anterior inguinal hernia repair is the second-most-commonly performed abdominal operation and has been associated with low morbidity and mortality rates. The principle of laparoscopy has been applied to this surgical problem in a series of 762 patients with 841 inguinal hernias. Four types of laparoscopic repairs were conducted: (1) high ligation of the(More)
Until the relatively recent interest in laparoscopic preperitoneal hernia repairs, most Surgeons in the United States and in many other countries performed open anterior repairs. There was little reason to study the preperitoneal anatomy. Surgeons involved with laparoscopic and open preperitoneal hernia repairs work in the preperitoneal fascial planes and(More)
