The patient was 80 years old and presented with intestinal obstruction and perforation, which could be treated both non-surgically and surgically. For intestinal obstruction, the principle of treatment is to correct the systemic physiological dysfunction caused by intestinal obstruction and to relieve the intestinal obstruction immediately; intestinal perforation may cause hemorrhage, which requires immediate symptomatic treatment and evaluation of the need for surgical treatment of intestinal perforation. Non-surgical treatments include gastrointestinal decompression, correction of water-electrolyte and acid-base balance disorders caused by obstruction, prevention of infection, and rehydration, etc. The above treatments can be used as conventional conservative treatments or to prepare for surgery. If the patient is strangulated intestinal obstruction, immediate surgery is needed. If part of the intestinal tube has been inactivated and necrotic, intestinal resection and anastomosis can be done for patients with intestinal perforation; if the condition is more complicated or the patient’s general condition is particularly poor, intestinal stoma or external intestinal placement can be considered, and then the intestinal tract can be reconstructed at a later stage. If intestinal obstruction or intestinal perforation occurs, patients should go to the hospital immediately to clarify the condition and give reasonable treatment to avoid delaying the condition.
