Diarrhea after bariatric procedures: Diagnosis and therapy

Figure 1 Laparoscopic sleeve gastrectomy. The greater curve of the stomach is resected alongside a bougie.

Figure 2 Proximal Roux-Y gastric bypass. The stomach is divided to form a small gastric pouch. Alimentary Roux-Y limbs of up to 150 cm and a biliopancreatic limbs of around 50 cm are formed; the resulting common channel is of various length depending on length of the whole small bowel.

Figure 3 Distal Roux-Y gastric bypass. The same principles as in proximal RYGB are applied; however, the length of the common channel, mostly around 100 cm, is the determined factor and the alimentary limb is of variable length. RYGB: Distal Roux-Y gastric bypass.
