[New concept in weight loss surgery: precise laparoscopic gastric bypass surgery]

Modern weight loss surgery has been transformed from the extensive mode to the precision mode. The new concept of precise laparoscopic Roux-en-Y gastric bypass(PLRYGB)embodies the advanced ideas of humanistic medicine, evidence-based medicine, minimally invasive treatment and so on. The ideal goal is to minimize trauma, maximize organ protection, minimize medical cost, and obtain the best effect of weight loss. This new concept will have broad prospects and probably become the mainstream idea in the field of weight loss surgery.
