Comparative outcomes of laparoscopic intraperitoneal mesh implantation versus transabdominal preperitoneal repair for umbilical hernia: a retrospective cohort study.
Article in Hernia : the journal of hernias and abdominal wall surgery, 2026. 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
objectiveThis study aimed to compare the intraoperative and postoperative outcomes of laparoscopic intraperitoneal onlay mesh repair (IPOM) and transabdominal preperitoneal repair (TAPP) for adult umbilical hernia and to provide clinical evidence for procedure selection.
methodsWe retrospectively reviewed adult patients with umbilical hernia who underwent laparoscopic IPOM or TAPP at a single tertiary referral center between July 2021 and July 2024. Baseline characteristics, operative variables, postoperative pain scores, and postoperative complications were compared between the two groups.
resultsA total of 69 patients were included, including 39 in the IPOM group and 30 in the TAPP group. Baseline characteristics were comparable between groups. The mean operative time was significantly longer in the TAPP group than in the IPOM group. However, postoperative VAS pain scores on the day of surgery and on postoperative days 1 and 7 were significantly lower in the TAPP group. No significant between-group differences were observed in intraoperative blood loss, length of hospital stay, postoperative complications, or recurrence during follow-up.
conclusionBoth laparoscopic IPOM and TAPP were safe and feasible for the treatment of adult umbilical hernia in this cohort. Although TAPP required a longer operative time, it was associated with lower short-term postoperative pain. No significant differences were observed in recurrence or complication rates. Larger prospective studies are needed to further clarify the comparative effectiveness of these two techniques.
