Background/Aim: Endometriosis infiltrating the rectum often requires resection with a protecting stoma. A ghost ileostomy (GI) is an alternative to prevent the psychological burden for the young women affected. The present study evaluated the safety and cost-effectiveness of the ghost ileostomy (GI) procedure in a group of patients after rectal resection for deep infiltrating endometriosis. Patients and Methods: The prospective controlled interventional trial was conducted in 54 consecutive patients with deep infiltrating endometriosis of the rectum. GI was considered after ultra-low resection with primary anastomosis, previous colorectal anastomosis, or pelvic redo surgery. Loop ileostomy (LI) was performed after simultaneous colpotomy with suture, only. Operating time, morbidity according to the Clavien-Dindo classification (CDC), duration of hospital stay, and patient satisfaction were obtained. Individual costs were estimated for the endometriosis procedure with or without a GI or LI, including stoma supply and closure expenses. Results: Of the 54 patients, 27 received GI (50%), whereas 4 underwent LI (7%). The remaining 23 patients received no outlet (NO). The complication rate did not differ among the GI, LI, and NO groups. Two cases were re-operated and required a diverting stoma, one in the GI and the NO group each. The additional healthcare expenses for each patient receiving a LI averaged 6,000 €. The patients were very satisfied with the option of a GI. Conclusion: GI is a cost-effective and safe alternative to LI after rectal resection for deep infiltrating endometriosis in cases where it is required. The individual costs per patient were reduced substantially, with a cumulative savings of 160,000 € in healthcare expenditure. Additionally, the method clearly lowers the psychological burden on the young women concerned.
