Banded Versus Conventional Laparoscopic Roux-en-Y Gastric Bypass (GABY).
The aim of this novel study is to evaluate, if an additional restrictive silastic ring can avoid dilation of the gastro-entero anastomosis and adjacent small bowel with consecutive better postoperative weight loss and significantly improved long-term weight maintenance.
The study will not investigate the GaBP-Ring as medical product but the effect of the GaBP-Ring on weight loss in comparison to gastric bypass alone.
GABY is designed as an international, multi center, open, prospective, randomized study to compare two methods of bariatric surgery: Banded versus conventional laparoscopic Roux-en-Y gastric bypass.
At least 16 international high volume centres of excellence in bariatric surgery and at least 384 patients (24 patients at each center) in total will be included into this study. At least 320 patients must have completed the study after 5 years.
Surgery will be performed according to standardized operating protocol. The group A (control group) will follow the worldwide golden standard of bariatric surgery (gastric bypass). Patients randomised to group B will receive in addition a restrictive silastic ring. The ring is a launched medical product and is registered in the European Community.
Allocation: Randomized, Control: Active Control, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Therapeutic practices which are not currently considered an integral part of conventional allopathic medical practice. They may lack biomedical explanations but as they become better researched some (PHYSICAL THERAPY MODALITIES; DIET; ACUPUNCTURE) become widely accepted whereas others (humors, radium therapy) quietly fade away, yet are important historical footnotes. Therapies are termed as Complementary when used in addition to conventional treatments and as Alternative when used instead of conventional treatment.

Excision of the gallbladder through an abdominal incision using a laparoscope.
Placement of one of the surgeon's gloved hands into the ABDOMINAL CAVITY to perform manual manipulations that facilitate the laparoscopic procedures.
Non-hematopoietic cells, with extensive dendritic processes, found in the primary and secondary follicles of lymphoid tissue (the B cell zones). They are different from conventional DENDRITIC CELLS associated with T-CELLS. They are derived from MESENCHYMAL STEM CELLS and are negative for class II MHC antigen and do not process or present antigen like the conventional dendritic cells do. Instead, follicular dendritic cells have FC RECEPTORS and C3B RECEPTORS that hold antigen in the form of ANTIGEN-ANTIBODY COMPLEXES on their surfaces for long periods for recognition by B-CELLS.
