Abstract:Objective:To study the diagnosis and treatment of chronic colonic pseudo-obstructon. Methods :The clinical data of 17 cases of chronic colonic pseudo-obstructon were analysed retrospectively. Results:All cases underwent surgical operation. Five cases had right hemicolectomy and transverse colectomy; 8 cases had right hemicolectomy, transverse colectomy and descending colectomy; 1 case had sigmoid colectomy; 1 case had sigmoid colostomy; and two cases had intestinal decompression procedures. After operation, 2 cases had infection of incisional wound, and 1 case had left subdiaphragmatic abscess,and the 3 patients recovered after treatment; 1 case had gastroplegia and recovered after expectant treatment for 30 days; 1 case undergoing intestinal decompression procedures died of septicaemia and septic shock 19 days after operation. Symptoms of 2 patient underwent sigmoid colectomy and one patient undergoing intestinal decompression procedures were not relieved after operation. The other patients recovered completely with normal passage of gas and defecating functions and no abdominal distension. Conclusions:Chronic colonic pseudo-obstructon is a rare disease. Excising dilated and nonfunctional colon can relieve the symptoms in most patients.
