A second drainage strip is inserted into the anteriorpart of the incision, in front of the anus. Vaginal Method.—Access to the rectum may be obtainedthrough an incision in the posterior wall of the vagina. After therectum has been exposed it is detached in the manner described inthe preceding operations,—perineal method. After the rectum has. Fig. 255.—Amputation of the Rectum (Quenu). The rectum has been ampu-tated and the lower edge of the sigmoid sutured to the edges of the anal drains emerge from the incisions in front of and behind the anus.

Sacral Route (Kraske).—The rectum is approached through anincision in the sacro-coccygeal region after the coccyx and usuallya portion of the sacrum have been removed. This plan of operationis well adapted to resection of a portion of the rectum, where thedisease is limited to the upper part of the rectum and the anal por-tion is healthy. It affords good access to the upper diseased part ofthe bowel. Through this route the diseased portion may be resectedand the upper end of the bowel brought down and sutured to thelower,
