Retrograde duodenogastroscopy solves the problem of postoperative evaluation of the gastric bypass patient. The stomach may be bypassed to treat morbid obesity, but it no longer need be inaccessible. Endoscopic gastritis is rare in the proximal gastric pouch but common in the distal gastric segment and may be related to the presence of bile. Although the gastric mucosa is histologically normal in half of the gastric bypass patients, acute and chronic gastritis, regenerative changes, and intestinal metaplasia may develop in either or both segments. The causes and implications of these endoscopic and histologic findings are unknown.
逆行十二指肠胃镜检查解决了胃旁路手术患者术后评估的问题。胃可能被绕过以治疗病态肥胖，但它不再难以触及。内镜下胃炎在近端胃囊袋中很少见，但在远端胃段很常见，可能与胆汁的存在有关。虽然一半的胃旁路手术患者胃黏膜在组织学上是正常的，但急性和慢性胃炎、再生性改变以及肠化生可能在其中一个或两个节段中发生。这些内镜和组织学发现的原因及影响尚不清楚。
