[Operation key points and efficacy evaluation of Jinling procedure for mixed refractory constipation]

For chronic transit constipation (STC), surgery should be considered when all pharmacological interventions, biofeedback, and sacral nerve stimulation failed to relieve severe symptoms. Chronic functional constipation can be subdivided into three subtypes: colonic slow-transit constipation, outlet obstruction and mixed refractory constipation. The pathological changes of colonic slow transit and outlet obstruction constipation can influence each other. Mixed refractory constipation accounts for 90.2% of chronic constipation. Therefore the surgery procedure should solve two types of pathological changes at the same time. The Jinling procedure combines subtotal colectomy and side-to-side cecorectal anastomosis, aiming to solve the coexistence of obstructive defecation and slow-transit constipation in one operation. A total of 1 768 patients with mixed refractory constipation received Jinling procedure from January 2001 to June 2016. Our clinical practice indicates that the Jinling procedure is safe and effective for refractory slow-transit constipation associated with obstructive defecation, with minimal major complications, significant improvement of quality of life, and a high satisfaction rate after long-term follow up. The safety and efficacy of Jinling procedure are improved continually with the progress of minimally invasive surgery, surgical instruments, recovery after surgery and perioperative management. Through long-term clinical and basic research, our institute has formed the comprehensive treatment strategy, such as Jinling procedure, intestinal microecological treatment, medication, biological feedback and sacral nerve stimulation in the treatment of functional constipation.
