Abdominoperineal pull-through with delayed coloanal anastomosis for pelvic anastomotic failure-a systematic review.
Synthesis in Techniques in coloproctology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimDespite the potential benefits of abdominoperineal pull-through with delayed coloanal anastomosis (DCAA), it is still infrequently performed as a salvage procedure for pelvic anastomotic failure. We aimed to perform a systematic review on the subject to guide practice.
methodPubMed, Embase and Cochrane were used to identify studies evaluating DCAA for salvage after pelvic surgery from inception to August 2024. Risk of bias assessment was performed using the Newcastle-Ottawa scale. The primary outcome was overall stoma-free survival. Secondary outcomes included hospital length of stay, high-grade postoperative complication rates, 30-day postoperative mortality rates, incidence of redo surgical intervention after DCAA, and postoperative anorectal function.
resultsFive retrospective cohort studies evaluating a total of 97 patients who underwent salvage abdominoperineal pull-through and DCAA were included in this review. All patients had previous pelvic surgery, predominantly proctectomy (n = 84, 86.6%). The most common indication for redo surgery was chronic fistula (n = 62, 63.9%) followed by anastomotic leak or chronic pelvic sepsis (n = 34, 35.1%). The pooled overall stoma-free survival rate across all five studies was 81.4% over a mean 24-month postoperative follow-up duration. The overall incidence of high-grade complications after DCAA was 39.1% (n = 38). Pooled mean length of stay was 17 days. There were no cases of early postoperative death. Pooled rate of repeat surgery across four studies was 11.6% (n = 8). Pooled mean functional scores across three studies indicated minor low anterior resection syndrome at 26 months.
conclusionAbdominoperineal pull-through with delayed coloanal anastomosis is a viable option for salvage surgery following pelvic anastomotic complications, with low rates of permanent stoma and acceptable long-term anorectal function.
