Best Suture Material for Omental Patch Repair

Optimal Suture Selection

• The American College of Surgeons recommends monofilament absorbable sutures for omental patch repair as they cause less bacterial seeding and may be less likely to cause infection compared to multifilament options 1, 2
• Monofilament synthetic sutures such as poliglecaprone and polyglyconate are preferred for omental patch repair due to their reduced bacterial seeding properties 3, 4
• The American College of Obstetricians and Gynecologists suggests that catgut should be avoided as it is associated with more pain and higher risk of requiring resuturing compared to synthetic options 3, 5

Specific Considerations for Omental Patch Repair

• For perforated peptic ulcers smaller than 2 cm, primary repair with monofilament suture is recommended by the World Journal of Emergency Surgery 1, 6
• For perforated marginal ulcers or gastric/duodenal perforations less than 1 cm, primary suture with omental patch in laparoscopic approach is strongly recommended in stable patients by the World Journal of Emergency Surgery 2
• The omental patch technique is particularly valuable in cases of large ulcers with friable edges to reduce the risk of sutures cutting through the edges, as reported by the World Journal of Emergency Surgery 1, 7

Evidence on Omental Patch Technique

• Multiple retrospective studies show low postoperative leak rates with the omental patch technique, even for perforations up to 2 cm in diameter, according to the World Journal of Emergency Surgery 1, 8
• However, several studies indicate that simple closure without an omental patch may have comparable results regarding leakage rates while requiring less operative time, as found by the World Journal of Emergency Surgery 1, 9
• A multicenter non-randomized retrospective study of 297 patients found no significant association between the type of repair (with or without omental patch) and complication rates, as reported by the World Journal of Emergency Surgery 10

Technical Considerations

• When using the omental patch technique, ensure the suture material has adequate strength to hold the omental patch in place without cutting through tissue, as recommended by the World Journal of Emergency Surgery 1, 10
• Continuous non-locking suturing techniques are preferred as they distribute tension more evenly across the suture line, according to the American Journal of Obstetrics and Gynecology 3, 5

Common Pitfalls and Caveats

• Avoid overly tight sutures that can strangulate tissue and impair healing, particularly important in vascular areas like the omental patch, as cautioned by the World Journal of Emergency Surgery 1, 7
• While omental patch may not be necessary for all repairs, it remains valuable for selected cases with friable tissue edges or larger perforations, as noted by the World Journal of Emergency Surgery 1, 7

Evidence‑Based Recommendations for Omental Patch Repair of Perforated Peptic Ulcer

Types of Omental Patch Repair

• The World Society of Emergency Surgery identifies three primary omental‑patch techniques for perforated peptic ulcer: (1) Graham patch omentopexy (standard multi‑stitch), (2) single‑stitch omental patch, and (3) combined omental plug‑and‑patch, with the choice guided by perforation size and tissue quality. 11

• Graham patch omentopexy is described as the “gold‑standard” technique that has been used for decades. 11

• In the Graham patch, multiple sutures are placed through the perforation edges and tied over a pedicled omental flap to seal the defect. 11

• This multi‑stitch approach requires advanced laparoscopic suturing skills and results in a longer operative time compared with simpler methods. 11

• The Graham patch is best suited for perforations with friable edges and poor tissue quality, where the omental reinforcement helps prevent suture cut‑through. 11

Primary Closure Without Omental Patch

• Simple suture closure without omental reinforcement yields leak rates and mortality comparable to Graham patch omentopexy for small perforations (< 2 cm). Evidence is based on multiple retrospective studies. 11

• Retrospective data also show that adding an omental patch to small perforations does not confer additional benefit but does significantly increase operative time. 11

Selection Algorithm (Based on Perforation Size and Tissue Quality)

• Perforations < 1 cm in hemodynamically stable patients: either a single‑stitch omental patch or simple primary closure may be used; outcomes are comparable, so the decision should be based on surgeon experience and tissue quality. (Evidence: World Society of Emergency Surgery) 11

• Perforations 1–2 cm with good tissue quality: simple primary closure without an omental patch is adequate and shortens operative time. (Evidence: World Society of Emergency Surgery) 11

• Perforations 1–2 cm with friable edges or questionable tissue quality: an omental patch should be added to reinforce the repair. (Evidence: World Society of Emergency Surgery) 11

Common Pitfalls (Evidence‑Based)

• Routine use of an omental patch for all small perforations (< 2 cm) is not recommended, as it prolongs operative time without improving clinical outcomes. (Evidence: World Society of Emergency Surgery) 11
