RYGB
Laparoscopic Conventional Roux-en-Y Gastric Bypass

General information
General information
Conventional Roux-en-Y Gastric Bypass (RYGB) is a well known bariatric surgical procedure. The operation reduces food intake and the absoption of nutrients because part of the intestines is bypassed and not used. The volume of the stomach pouch after LCRYGB is between 15 and 25 ml. The alimentary limb (AL, green in the image) in RYGB is 120 – 150 cm long, the biliopancreatic limb (BPL, pink in the image) consists of 50 cm of the small intestine.

Before Surgery
Indications for RYGB
- BMI 40 (or 35 with related diseases) to 50
treatment of:
– diabetes mellitus type 2
– arterial hypertension
– other related diseases - redo surgery after other metabolic operation in patients with high compliance
- accepts obligatory supplementation of vitamins and minerals
- sweet eaters
- patients with heartburn
Advantages
- successful (50-70% of excess weight loss)
- operation for patients, where restrictive procedures like Balloon Banding and Sleeve Gastrectomies have failed
- operation for stress eaters
- operation for patients with heartburn
Disadvantages
- sometimes dumping syndrome
- irreversible change in the anatomy
- lifetime vitamin and mineral supplementation after surgery
- conventional upper gastroscopy of duodenum and remnant stomach is not possible
The Surgery
Technical description
Laparoscopic Roux-en-Y Gastric Bypass reduces the size of the stomach through surgical stapling. This type of weight loss surgery cuts the stomach and leaves a reservoir, approximately the size of a walnut. Afterwards the biliopancreatic limb is measured (50 cm). The distal from separated intestines are connected to the stomach pouch (Gastro-enteroanastomosis GEA) mostly with the round stapling method. This causes the food to be directed immediately from the stomach to the jejunum. The small intestines junction called jejunojejuno anastomosis (JJA) is created 120 – 150 cm from the GEA.

Weight loss differences
The EWL after conventional RYGB reached 58.2% after five years in the best series. Bessler performed the first prospective study that directly compared the two operation methods. After the second or third postoperative year, the patient seems to adapt to the surgery and suffers side-effects in lower intensity, which brings a tendency to regain some of the lost weight.
Important tips
A team of experts must approve the surgery before RYGB operation.
Because we promote safe practice and your safety is of paramount high importance to us and to you, the disadvantages and advantages of the different procedures will be carefully explained to you in detail on consultation.
