Exit-obstruction constipation refers to poor or obstructed bowel movements after reaching the rectum and anus. The main manifestations are straining to defecate, prolonged defecation time, poor emptying, feeling of obstruction at the anus, feeling of incomplete defecation, distension and pain in the rectum and anus during defecation, and sometimes needing to use hand assistance or enema to defecate. Anterior rectal protrusion and endorectal prolapse are common diseases that cause outlet obstruction type constipation. For these patients, surgery is considered after systematic conservative treatment (e.g., dietary modification, laxatives, intestinal microecological agents, and biofeedback training) has failed. STARR technique (anastomotic transanal proctocolectomy) is a routine procedure for the treatment of anterior rectal protrusion and endorectal prolapse. This technique removes the entire anterior and posterior walls of the diseased rectum in two steps through the anus using two anastomotic clutches, simultaneously removing the anterior rectal protrusion and endorectal prolapse, eliminating the anatomical cause of mechanical obstruction, and restoring rectal volume and compliance. In the past year, we have been using the leading international technology TST-STARR+ for the treatment of rectal prolapse and endorectal prolapse. The advantages of this technology compared with STARR: (1) more rectal lesions are removed by a new type of circular anastomosis with larger volume; (2) the four directly viewable openings of the special anastomosis make the operation process safer and faster and make the extent of resection of the rectum more accurate. It is reported that the Department of Colorectal Surgery of Wuhan University Central South Hospital has successfully performed this surgery for more than 100 patients with prolapsed rectum and endorectal prolapse in the past one year. The procedure has the advantages of minimally invasive, good efficacy, fast recovery and short hospital stay. The 62-year-old female patient, who gave birth to three children vaginally when she was young, had mild defecation difficulties when she was young, and her symptoms have worsened in the past five years, and was diagnosed with severe rectal prolapse combined with endorectal prolapse after examination and fecal imaging. Four days later, the patient enjoyed a long-awaited smooth bowel movement and was successfully discharged on the fifth day.
