Feasibility of the TAMIS technique for redo pelvic surgery

Aim: 

The aim of this study was to report on the feasibility of transanal minimally invasive surgery (TAMIS) as a novel approach to redo colorectal or ileoanal anastomoses. 

Methods: 

From October 2014, a prospective institutional database was created for all consecutive patients who underwent redo surgery by TAMIS for presacral sinus or anastomotic stenosis after low anterior resection or pouch-related problems following restorative proctocolectomy. Intra-operative feasibility, 30-day postoperative outcomes, intestinal continuity and complications after 6-month follow-up were evaluated. 

Results: 

Of 17 included patients, 14 underwent anastomotic reconstruction and three completion proctectomy. The median operation time was 265 min (range 201–413). A successful rendezvous with simultaneous transabdominal access was achieved in 15 patients, and the procedure was completed by TAMIS alone in two. Five patients were readmitted within 30 days (29 %). Two (14 %) patients developed an anastomotic leakage within 30 days and 4 (24 %) developed a pelvic abscess requiring reintervention. One patient developed an urethra stenosis and was managed with a suprapubic catheter. Median follow-up was 9 (6–15) months. Within 6-month follow-up, the redo-TAMIS 1 patient developed a delayed anastomotic leak and 1 patient had a recurrent presacral abscess after stoma closure. Intestinal continuity was reached in 71 % of the patients at 6-month follow-up. 

Conclusion: 

TAMIS is a valuable approach in redo pelvic surgery, but is still associated with high complication rates related to the complexity of the underlying problem.
