Background technique

Ponsky method is a minimal invasive techniques, and doctor opens under gastroscope help in patient abdomen one small Hole is simultaneously put into nutrition pipeline, can provide nutrition by nutrition pipeline for patient, which changes needs abdominal in the past Traditional approach, it is only necessary to local anaesthesia, it is simple and convenient for operation, the risk and postoperative complications of patient are reduced, nutrient canal is more general Logical Nasal gastrointestinal tube is durable, standing time even can be with 1 year and a half more than, significantly solve cannot by normal gut feed Problem, hence it is evident that eliminate the sense of discomfort of patient's pharynx nasalis, while having both certain cosmetic result, patient can be in after setting pipe " self feeding " simultaneously normally participates in various social activitieies, has become at present and is clinically unable to oral feeding but needs supply of long duration The prefered method of nutrition patient.

Ponsky method comprises the steps of:

1, conventional method determines point of puncture using gastroscope light source into gastroscope；

2, conventional transdermal disinfection, drape, local anaesthesia are cut skin, are vertically pierced into stomach with No. 16 trochars；

3, needle core is extracted, annular seal wire is sent into；

4, it is inserted into snare, be locked annular seal wire, exits together with gastroscope；

5, the annular seal wire for pulling out oral cavity and the annular seal wire of fistulization pipe end are entangled firm in " 8 " font latch closure；

6, the annular seal wire for pulling stomach wall side reaches stoma direct oral cavity, oesophagus, cardia in stomach, by abdominal artificial-fistula mouth It pulls out；

7, it observes fistulization tube head into mirror again and contacts whether suitable, fixed stoma and connector with stomach wall.

Ponsky method operation sequence is complex, and operation precision requires height, and gastroscope inserts into patient's food Road, which will cause patient, foreign body sensation and stress, when the surgical due to lacking practical operation experience not enough skillfully easily leads to operation Long increase further results in patient's discomfort, it is therefore necessary to which in the case where the doctor for lacking practical operation experience is formally engaged in Percutaneous endoscopic, stomach is made Fistula is preoperative by simulated training, skillfully grasps operating process, hints on operation and points for attention.Make doctor in clinical operation with refined Ripe operation completes Ponsky method to mitigate the pain of patient, improve operation safety.
