The occurrence of stomach pain after the healing of intestinal obstruction is mainly seen in two clinical situations: first, the recurrence of intestinal obstruction; second, the primary cause of intestinal obstruction has not been fundamentally treated. Because most of the intestinal obstruction is caused by adhesional intestinal obstruction after abdominal surgery, clinical treatment usually adopts conservative treatment such as fasting, gastrointestinal decompression, anti-infection, fluid replacement, etc., and most patients can get relief of symptoms. If care is not taken in diet or warmth, there is a possibility of recurrence and another conservative treatment. If the primary cause is not cured, such as mechanical intestinal obstruction or incomplete intestinal obstruction caused by intestinal tumor is relieved for a short period of time by conservative treatment, but because the intestinal tumor is still not removed, it will certainly lead to another attack, and further colonoscopy is needed, and surgery is required after a clear diagnosis.
