Oesophageal flap valvuloplasty and wrapping suturing prevent gastrooesophageal reflux disease in dogs after oesophageal anastomosis

Figure 1 Oesophageal flaps and “sleeve joint”. A: A longitudinal cut on the distal oesophageal about 2-3 cm in length; B: A stoma in the anterior wall of the stomach forming a “sleeve joint”, which was 2 to 3 mm longer than the oesophageal diameter.

Figure 2 Oesophageal flap valvuloplasty. The seromuscular layer of the interrupted absorbable monofilament suture was used to suture the 1 cm-long fold around the remnant oesophageal flaps in the AA₁ site forming modified oesophageal flaps.

Figure 3 Wrapping suturing of the stomach wall around the oesophagus. The seromuscular layer of the oesophagus and the gastric wall was sutured in the BB₁ site and CC₁ site. The BB₁ site was located just above the end of the oesophageal flaps and the distance between BB₁ and CC₁ should be 2 cm.
