Proctopexy with sigmoid resection, abdominal approach, is a surgical procedure aimed at addressing rectal prolapse, a condition where the rectum protrudes through the anus. This procedure is particularly indicated when the prolapse is significant and requires not only the fixation of the rectum to the sacrum but also the removal of a portion of the sigmoid colon and upper rectum to facilitate proper anatomical alignment and function. The surgery involves a midline abdominal incision, through which the sigmoid colon and rectum are carefully dissected from the surrounding presacral fascia. This dissection allows for the mobilization of the rectum, enabling the surgeon to access the presacral space and reduce the prolapse effectively. The procedure is characterized by the interruption of the vascular supply to the affected segment, which is achieved by ligating and dividing the inferior mesenteric artery or the individual sigmoid arteries. Following the resection of the sigmoid colon, the remaining segments are sutured together in a process known as anastomosis, ensuring continuity of the bowel. This comprehensive approach not only addresses the prolapse but also aims to restore normal bowel function and prevent recurrence of the condition.
