Li Zheng is like a super hunter, not letting go of any damaged area on the intestines.

In less than half an hour, Li Zheng repaired all the perforations in the jejunum, ileum, and colon.

In the end, only the perforation of the rectum was left.

The rectum is relatively thick and has two oblique perforations.

Li Zheng first exposed the ischiorectal fossa and cleaned it thoroughly.

Then remove the necrotic tissue around the rectal perforation and suture the rectum directly in layers.

After the rectum is treated, the main surgical operations in the abdominal cavity are completed.

Next, prepare to close the chest and abdomen.

Before that, Li Zheng used more than 5,000 milliliters of warm saline to thoroughly flush the abdominal cavity, focusing on the pelvic cavity, paracolic gutter, and subdiaphragm.

Li Zheng placed closed drainage in the chest cavity, and porous silicone drainage tubes in the abdominal cavity at the perforation repair site, the lowest point of the pelvic cavity, and the subhepatic space, and drained them out through holes punctured in the abdominal wall to avoid compression of the intestinal tract.

Li Zheng was so professional and skilled in placing the drainage tube that Director Lei felt very uncomfortable.

When I was working in my own department, I had to personally check before placing drainage tubes.

But now, Li Zheng didn't ask anyone at all, and he placed several drainage tubes very well by himself with ease.

Close the chest first.

Li Zheng closed the chest wall and then used steel wire to tie the severed ribs.

The chest wall is then sutured layer by layer.

Li Zheng used 1-0 absorbable sutures to suture the peritoneum continuously on the abdomen, intermittently suture the anterior sheath of the rectus abdominis, then suture the subcutaneous tissue, and finally cut and suture the skin.

The wound was too long and the patient was a man, so Li Zheng did not use cosmetic sutures but ordinary interrupted sutures.
