A prospective observational study comparing conventional lateral border transfascial mesh fixation versus midline transfascial suturing in laparoscopic intraperitoneal onlay mesh repair for umbilical hernia- a pilot study.
Observational study in BMC 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
backgroundConventional lateral border transfascial mesh fixation in laparoscopic intraperitoneal onlay mesh (IPOM) repair for umbilical hernia is associated with significant postoperative pain due to nerve entrapment in the lateral abdominal musculature. Midline transfascial suturing, targeting the less-innervated linea alba, may offer improved pain outcomes without compromising mesh stability.
methodsThis prospective observational study included 62 patients undergoing laparoscopic IPOM repair for primary umbilical hernia with defect size < 6 cm. Patients were allocated based on surgical unit protocol: 31 underwent midline transfascial suturing (Midline group) and 31 underwent conventional lateral border transfascial fixation (Lateral group). Primary outcomes were postoperative pain assessed by Visual Analogue Scale (VAS) at predetermined intervals (postoperative days 1, 2, 7, 14, and 60), operative time, and length of hospital stay. Secondary outcomes included recurrence, complications, and patient satisfaction using the Patient Satisfaction Questionnaire (PSQ).
resultsBaseline demographics including age, gender, body mass index, and defect size were comparable between groups (p > 0.05). The Midline group demonstrated significantly lower VAS scores at all time points: POD1 (2.81 ± 0.64 vs. 4.32 ± 0.60, p = 0.001), POD7 (2.13 ± 0.50 vs. 3.23 ± 0.72, p = 0.001), and POD60 (0.52 ± 0.51 vs. 1.36 ± 0.66, p = 0.001). Hospital stay was significantly shorter in the Midline group (2.48 ± 0.51 vs. 3.48 ± 0.51 days, p = 0.001). Patient satisfaction scores were higher with midline fixation (8.76 ± 0.25 vs. 6.76 ± 0.25, p = 0.001). Operative time was comparable between groups (80.19 ± 12.27 vs. 81.52 ± 10.80 min, p = 0.654). Recurrence rates were similar (9.7% vs. 12.9%, p = 0.688). The Midline group had no complications, while the Lateral group had 16.1% (seroma 9.7%, surgical site infection 6.5%; p = 0.066).
conclusionMidline transfascial suturing in laparoscopic IPOM repair for umbilical hernia significantly reduces postoperative pain, shortens hospital stay, and improves patient satisfaction compared to conventional lateral border fixation, with comparable operative time and recurrence rates. This technique represents a patient-friendly alternative that should be considered for small-to-medium umbilical hernias.
