Description

Gastric pylorus occlusion balloon

Technical Field

The utility model relates to the technical field of medical devices, in particular to a gastric pylorus blocking air bag.

Background Art

Endoscopic submucosal dissection (ESD) is a new minimally invasive technique used in recent years to treat early gastrointestinal tumors. It has the advantages of less trauma, faster recovery, higher lesion resection rate and shorter hospitalization time.

ESD is performed under endoscopy, which has the disadvantages of limited viewing angle of the lesion site and limited operating space. Therefore, carbon dioxide needs to be continuously injected into the distension cavity during ESD to maintain gastric expansion and flattening of the gastric mucosa, so as to better reveal the surgical field of view. The carbon dioxide continuously injected during the operation enters the intestine through the pyloric canal and fails to be discharged in time, resulting in intestinal flatulence. Existing literature reports that the incidence of postoperative abdominal distension in patients undergoing gastric ESD surgery averages 13.75% to 37.5%. When young physicians perform ESD surgery, 19 out of 21 ESD patients experience upper abdominal discomfort due to reasons such as carbon dioxide inflation pressure and lack of proficiency in surgical operations.

Abdominal distension and pain caused by intestinal bloating after surgery may mask and delay the identification of gastric wall perforation and gastric bleeding; the accumulation of a large amount of carbon dioxide in the intestine causes an increase in intra-abdominal pressure, which affects the body's abdominal breathing, causing postoperative respiratory dysfunction, decreased blood oxygen saturation, respiratory acidosis, etc.; during general anesthesia and mechanical ventilation, intestinal bloating causes the diaphragm to lift, resulting in increased mechanical ventilation airway pressure and carbon dioxide retention, which can severely lead to intraoperative hypoxemia; when performing gastric ESD under general anesthesia, if there is a long-term (more than 60 minutes) high-pressure state of carbon dioxide in the intestine, even if the patient has reached a state of hyperventilation in advance, the patient's arterial _PaCO2 level will increase by 40%, increasing the risk of anesthesia management.

In order to reduce intestinal bloating during surgery, the anesthesiologist and circulating nurse during gastric ESD surgery should continuously observe the patient's abdominal distension, promptly remind the surgeon to stop injecting gas into the stomach, and check whether gastric perforation occurs during the operation; if necessary, insert the gastroscope deep into the duodenum to absorb the accumulated gas, eliminate intestinal bloating, and reduce abdominal distension. Possible adverse consequences: 1. Delay in the surgical process and prolong the operation time; 2. Deeply absorb the accumulated gas into the duodenum, and improper operation may damage the intestinal mucosa.

To this end, a gastric pylorus occlusion balloon is proposed, which is used to isolate the stomach and intestines for a short time, avoid intestinal gas accumulation and abdominal distension, improve postoperative comfort, reduce postoperative complications, and improve the safety of gastric ESD surgery.
