Internal hernia

After the major gastric resection, the remnant stomach and the jejunum are anastomosed, and the gap left behind the anastomotic opening is called the posterior anastomotic space (Figures 1, 2, 3). Its edge lacks elasticity and resembles a hernia ring. If the bowel crests protrude into the anastomotic space and it is difficult to recover naturally, a postgastrectomic inteRNAl hernia is formed. Complicated internal hernias after gastrectomy rarely occur clinically. They are more common after Billroth Ⅱ type gastrectomy and gastric jejunostomy. They can occur early or late after surgery. The inferior posterior space formed by the post-colonic gastrojejunostomy is the most common hernia.
