Risk factors for rectal perforation during presacral cyst removal: a comparison between transabdominal, perineal, and combined surgical approaches.

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
backgroundThis study aimed to evaluate the risk factors associated with rectal perforation during various surgical interventions for presacral cysts.
methodsThis retrospective study included 73 participants from 2013 to 2023 who met the inclusion criteria. Participants underwent surgical treatments through transabdominal, perineal, or combined approaches. Preoperative assessments of presacral cysts were performed using computed tomography (CT) and magnetic resonance imaging (MRI). Biannual postoperative follow-ups involved ultrasound, CT, or MRI scans. Data analysis was conducted using RStudio software.
resultsThe incidence of rectal perforation did not differ significantly across surgical approaches [combined 2 (18%) vs. perineal 3 (8.8%) vs. transabdominal 4 (14%), P = 0.7]. Cyst capsule rupture was more frequent in the transabdominal and combined approaches [17 (61%) and 5 (45%), respectively] versus perineal approach [8 (24%), P = 0.011]. The laparoscopic subgroup experienced a higher rate of cyst rupture compared to the robotic subgroup, with rectum perforation cases only correlating with ruptures in the robotic subgroup. Intraoperative complications prompted conversions to open surgery in the laparoscopic group, unlike in the robotic group. Postoperative follow-up revealed no mortalities, with malignant transformation observed in two cases and local recurrences in three. While univariate analysis did not identify significant predictors of rectal wall perforation, multivariate analysis suggested that the risk of perforation increased with cyst rupture and decreased when the cyst was located further from the anal verge.
conclusionsThe study identifies two primary risk factors for rectal wall perforation: the cyst capsule integrity and the cyst-rectum shortest distance, with the latter being accurately determined by MRI. These findings may inform further surgical planning and risk assessment.
