Selective gastric vagotomy

It is mainly used in patients with duodenal ulcers with indications for surgical treatment, such as bleeding (including some stress ulcer bleeding), perforation, scarring pyloric obstruction, refractory ulcer and simple gastrointestinal anastomosis or partial gastric resection Postoperative anastomotic ulcers. There are two types of vagal amputation: vagus nerve amputation and selective vagus nerve amputation. The former is easy to operate, but often has symptoms such as abdominal distension and diarrhea after surgery, which is suitable for more severe patients; the latter has less disruption of gastrointestinal function after surgery, but the surgery is more complicated and suitable for surgical tolerance Better patient. Both of them must be added with gastric drainage or partial gastric amputation in order to complete the operation. In recent years, highly selective gastric vagotomy (also called parietal cell vagotomy) has been developed. The vagus nerve is only severed in the cell wall of the gastric wall, without the need for additional gastric drainage or hemi-gastric or sinus resection. It can be performed as an independent operation. This operation method has its great advantages in theory, but the operation requirements are strict. The three methods are shown in the diagram [Figure 1].
