Rigid abdomen only occurs with conditions such as acute gastrointestinal perforation, organ rupture, and acute peritonitis.
The uncle has experienced bloody stools, and it has been going on for several days.
Now the bloody stool is worsening, and abdominal pain is intensifying, all indicating the progression of the disease, and it's coming aggressively.
"Does it hurt here?"
"Yes."
"Is it just a little pain or very painful?"
"Quite painful."
Just after the uncle answered, Li Jingsheng slightly increased the pressure.
"Ow... it hurts, it hurts!"
Li Jingsheng immediately withdrew his hand, judging that the pain location for the uncle should be in the jejunum.
The small intestine is part of the digestive tract, divided into the duodenum, jejunum, and ileum.
Interestingly, the medical separation between the upper and lower gastrointestinal tract is marked at the duodenum.
The suspensory ligament of the duodenum is also known as the ligament of Treitz.
