Application of a novel small intestine decompression method in patients with intestinal obstruction: A retrospective cohort study

Figure 1 Cannula. Outer tube (purple arrow), internal tube (orange arrow), and side perforations of the tube (blue arrow); the black arrow indicates the junction where air can enter.

Figure 2 Small intestine incision decompression method. A: The small intestine was pulled out of the incision using silk thread. The gauze was placed underneath, and the intestinal tract was cut open; B: The intestinal tube was squeezed segment by segment in the direction of intestinal peristalsis with the index and middle fingers, and the intestinal contents were discharged into the container; C: The intestinal contents were collected in a storage bag and transferred into a measurable container, after which the degree of pressure reduction was calculated.

Figure 3 Small intestine tube decompression method. A: A purse-string suture with a diameter of approximately 1 cm was placed on the small intestine wall; B: Fingers were used to control the proximal intestinal tract as the intestinal wall was cut open the; C: The cannula was inserted, and fingers were released to perform the small intestine decompression.
