Background technique

For patients with reflux esophagitis who require esophagectomy, a segment of the jejunum or colon can be used as an alternative to reconstruct the digestive tract. According to the observation of histamine stimulation, the jejunum or colon in the new location is more resistant to acid pepsin digestion than the duodenum, and the transplanted jejunum retains not only its peristaltic form but also the segmental contractions of the intestine , similar to sphincter function. The intestinal wall is smooth muscle tissue, which does not cause fatigue and can meet the physiological needs of patients with reflux esophagitis.

The traditional double-layer anastomosis is usually used for esophagografted intestinal segment anastomosis, with one full-layer anastomosis and a wrapping layer. However, in recent years, many scholars have adopted the one-layer interrupted suture method, and the effect is also good.

Esophageal transplantation intestinal anastomotic leakage is a serious complication. Once anastomotic leakage is confirmed, jejunostomy is given to maintain nutrition; thoracic drainage and suction with negative pressure; nasogastric tube continues to drain gastric juice, and the drained gastric juice is reinfused into the jejunostomy every 2 hours to maintain digestive enzymes Balance with water and electrolytes, the so-called "three-pipe therapy". If the anastomotic leakage is large and it is difficult to be cured by three-tube therapy, esophagus transplanted intestinal anastomosis should be performed again, esophagus transplanted intestinal tube reanastomosis, or the transplanted intestinal segment should be sealed, the esophagus is pulled out from the neck incision, and empyema should be treated first. , the second stage of colon replacement of esophagus, digestive tract reconstruction.

However, at present, there is no timely and effective drainage device for esophageal transplantation for intestinal anastomotic leakage, especially when the leakage or exudate flows into the spleen fossa, it will increase the difficulty of drainage. If it cannot be drained out of the body in time, various complications will occur, and in severe cases, the patient will die.
