Modified 2-stage ileal pouch-anal anastomosis versus 3-stage alternative

Similar long-term outcomes were reported for participants who received modified 2-stage or 3-stage ileal pouch-anal anastomosis (IPAA). However, the modified 2-stage approach should only be performed by experienced surgeons at high-volume centres and in a select group of patients.

Long-term outcomes of modified 2-stage IPAA have not yet been evaluated, according to Dr Stefan Holubar (Cleveland Clinic Foundation, OH, USA) [1]. The modified 2-stage approach is defined as completion proctectomy without loop ileostomy, whereas the 3-stage approach includes completion proctectomy with loop ileostomy. For this study, 223 participants from the Adult Pouch Registry who underwent modified 2-stage IPAA between 1983 and 2019 were matched with 223 participants who underwent 3-stage IPAA. The primary outcome was pouch survival, defined by permanent diversion, pouch excision, and conversion to a Kock pouch.

Long-term pouch survival outcomes were similar between participants who underwent modified 2-stage or 3-stage IPAA (95.5% vs 93.2%; P=0.32; see Figure). However, 3-stage participants had a shorter postoperative length of hospital stay than modified 2-stage participants (5 vs 8 days; P<0.001). Also, a numerically but not significantly higher complication rate was reported in the modified 2-stage arm (17.0% vs 12.1%; P=0.09). Functional outcomes were mostly similar for the investigated approaches. The number of stools per 24 hours was 7 in both groups. Similarly, the proportion of participants requiring seepage protection at night did not significantly differ between the 3-stage and modified 2-stage arm (29.7% vs 24.6%; P=0.31). Participant satisfaction levels were comparable.

Dr Holubar said that modified 2-stage IPAA may be an alternative for patients with limited options. However, he emphasised that the modified 2-stage approach should only be performed by experienced surgeons in high-volume centres. Moreover, the eligible patient profile for modified 2-stage IPAA is highly selective. “Patients should display minimal pouch tension, 3 or lower on a scale from 1 to 10, have perfect betadine leak tests prior to anastomosis, and perfect endoscopic leak tests after anastomosis. Also, the physiology of the patient needs to fit the procedure.”
