Small-bites midline closure,
does it really help with Reduced one-year incisional hernia versus at least 10 mm bites and 10 mm advances with 1 PDS Plus II?

30-Second Summary
B
Evidence Grade B · 72 · Safety caution
Small-bites closure reduced one-year incisional hernia after elective midline laparotomy.
Fascial closure is a specialist surgical technique that must account for tissue quality, contamination, incision length, and tension. Infection, dehiscence, pain, and other operative risks remain relevant.
What the
research shows
The grade is B. STITCH randomized 560 patients and included 545 in the one-year outcome analysis. Incisional hernia occurred in 35/268 (13%) with small bites versus 57/277 (21%) with large bites, adjusted OR 0.52 (95% CI 0.31 to 0.87). The hard-event absolute difference was 8 points, but independent confirmation is absent and 15 randomized patients were not in the primary analysis, giving B with 72 points.
What the
ads claim
Small bites are a trained operative technique involving spacing, bite depth, suture-to-wound ratio, and suture material. Not every closely spaced stitch can claim the STITCH result.

Useful facts when choosing a product

  • Small bites used 5 mm by 5 mm placement and 2-0 PDS Plus II; controls used at least 10 mm by 10 mm and 1 PDS Plus II.
  • The trial was registered as NCT01132209 and NTR2052 with 12-month incisional hernia as primary.
  • The 2026 long-term report is follow-up of the same STITCH cohort, not independent randomization.

What the research actually shows

The Dutch multicenter STITCH trial randomized 560 elective midline laparotomy patients. Patients and study investigators were masked, and 12-month incisional hernia was prespecified. Among 545 analyzed, events were 35/268 versus 57/277, adjusted OR 0.52 (0.31 to 0.87). Ethicon Investigator Initiated Clinical Research Funding Grant 09-107 and Erasmus MC Efficiency Research Grant 2008-8106 jointly funded it; the report states funders had no role in design, conduct, analysis, interpretation, or writing. The 2026 13-year report follows the same NCT01132209 participants and is not a separate trial.

02

Why this is classified as B (72)

A large mixed-funded randomized trial substantially reduced a hard clinical event, but incomplete all-randomized analysis and no independent confirmation give B with 72 points.

Counterpoint. Verdict 2401 is B with 76 points for prophylactic mesh, a different intervention that was not pooled with suture-bite technique.

Rejudgment record. Cross-check applied — The STITCH paper, NCT01132209, NTR2052, and 2026 long-term report were checked for primary outcome, analyzed count, funding, and same-trial status

Sub-claim grades by effect

This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.

Effect (sub-claim)GradeBasis
Reduced one-year incisional hernia with the closure-technique packageBRates were 13% versus 21%, adjusted OR 0.52.
An isolated effect of 5 mm spacing alone?Suture caliber and needle also differed, so spacing alone cannot be isolated.

Cross-check — Codex and Claude

This verdict was drafted by Codex through literature review and source-existence checks, cross-checked through blind grading and adversarial audit, and settled by reapplying the methodology boundary rules. Cases with split grades were resolved through rejudgment.
