I now have comprehensive information. Let me compile the full, well-structured answer.

Methods of Peptic Ulcer Perforation Repair

Repair of a perforated peptic ulcer (PPU) is guided by the perforation's location (gastric vs. duodenal), size, underlying pathology (H. pylori, NSAID, malignancy, idiopathic), the patient's physiologic status, and whether definitive acid-reduction surgery is needed. Options span from non-operative observation to endoscopic techniques to open surgical resection.

1. Non-Operative Management (Taylor's Method)

Reserved for a highly selected subset of patients with small, contained perforations who are:

Hemodynamically stable
Without free peritoneal spillage on contrast CT
Without clinical peritonitis

Management involves: NPO, nasogastric suction, IV fluids, broad-spectrum antibiotics, and a PPI. Patients must be closely monitored and taken to surgery immediately if they fail to improve within 12-24 hours, develop peritoneal signs, or show continued extravasation on follow-up imaging.

Contraindications: Free intraperitoneal contrast extravasation, hemodynamic instability, or any sign of generalized peritonitis.

Fischer's Mastery of Surgery, 8th ed., p. 7744

2. Simple Primary Closure (Suture Repair)

The most widely performed technique, particularly for duodenal perforations.

The edges of the perforation are debrided of non-viable tissue
Closed with full-thickness interrupted or running sutures, then reinforced with a second layer of interrupted serosal Lembert sutures
Alternatively, a linear stapler can be used for speed and reduced technical variability (edges elevated with Allis/Babcock clamps or stay sutures)
If the perforation encroaches on the pylorus, closing it directly risks gastric outlet obstruction - a pyloroplasty (Heineke-Mikulicz) incorporates the perforation into a transverse closure to prevent narrowing

Simple primary closure is appropriate when the perforation is caused by H. pylori or NSAIDs and definitive acid-reduction is not needed (which is the case in most modern patients).

Fischer's Mastery of Surgery, 8th ed., pp. 7748-7749

3. Graham Patch (Omental Patch Repair)

The classic technique for duodenal ulcer perforation and a widely used adjunct for all PPU repair.

Steps: Loose sutures are placed across the perforation edges (not tied immediately). A pedicle of healthy, viable omentum is brought up to the perforation and the pre-placed sutures are tied over it, buttressing the repair without tension.
The omentum supplies blood supply and sealing capacity, reduces the risk of suture line leakage.
This technique is suitable even for perforations that are too necrotic or inflamed to hold a primary suture repair.
It can be performed both open and laparoscopically.

Bailey & Love's Short Practice of Surgery, 28th ed., p. 2217; Fischer's Mastery of Surgery, 8th ed.

Falciformopexy (Ligamentum Teres Patch)

A variant using the falciform ligament/ligamentum teres instead of omentum - useful when omentum is unavailable (prior surgery, severely diseased omentum). A 2025 systematic review and meta-analysis (PMID: 39991919) found it to be safe and effective with outcomes comparable to omental patch repair.

4. Wedge Resection

Indicated for perforations along the greater curvature of the stomach, or when tissue quality is too poor for primary suture repair.

The omentum is cleared from the greater curve adjacent to the perforation
A linear reinforced stapler is used to excise the perforated tissue in a "V"-shaped fashion, with 5-10 mm healthy margins
Oversewing the staple line is generally not required
Has the advantage of providing an adequate biopsy specimen (important given ~5% malignancy risk in spontaneous gastric perforations)

Fischer's Mastery of Surgery, 8th ed., p. 7750

5. Pyloroplasty with or without Vagotomy

For perforations near or involving the pylorus, or in patients with refractory ulcer disease.

Pyloroplasty (Heineke-Mikulicz)

The perforation is incorporated into a longitudinal pylorotomy incision
Closed transversely, widening the pyloric outlet
Prevents functional gastric outlet obstruction after perforations near the pylorus

Vagotomy + Drainage (V+D)

Truncal vagotomy (or highly selective vagotomy, HSV) combined with a drainage procedure (pyloroplasty or gastrojejunostomy)
Historically used as a definitive acid-reducing procedure for perforated duodenal ulcer
Now much less common given that H. pylori eradication and PPIs render definitive acid surgery unnecessary in most cases
Still indicated in patients with chronic refractory PUD despite maximal medical therapy, or those who perforated despite adequate H. pylori treatment

Schwartz's Principles of Surgery, 11th ed., pp. 1155-1156; Fischer's Mastery of Surgery, 8th ed.

6. Antrectomy with Reconstruction

For perforations near the pylorus or lesser curvature, or in refractory PUD where resection of the acid-producing antrum is needed.

The gastric antrum and perforated tissue are resected
Reconstruction options include:
- Billroth I (gastroduodenostomy)
- Billroth II (gastrojejunostomy)
- Roux-en-Y gastrojejunostomy
In an acutely unstable patient, source control is obtained by resecting the antrum first, then temporarily closing the abdomen and returning for reconstruction once the patient stabilizes (damage-control approach)

Fischer's Mastery of Surgery, 8th ed., p. 7750

7. Laparoscopic Repair

Laparoscopic approaches to all the above techniques (primary closure, Graham patch, wedge resection) are now well-validated.

A 2025 systematic review and meta-analysis (PMID: 39361132) confirms laparoscopic repair is at least equivalent to open repair for PPU, with fewer surgical site infections and less postoperative pain
A 2026 meta-analysis (PMID: 41342296) compared interrupted sutures vs. knotless barbed sutures laparoscopically - barbed sutures significantly reduce operative time without compromising outcomes
Absolute contraindications: hemodynamic instability precluding pneumoperitoneum, or lack of laparoscopic expertise

8. Endoscopic Repair

Emerging option, generally reserved for:

Small perforations (typically <10-12 mm)
Patients who are poor operative/anesthesia candidates
Iatrogenic perforations (e.g., post-ERCP, post-EGD)

Techniques include:

Endoscopic clips (through-the-scope or over-the-scope clips, e.g., OTSC system)
Self-expandable covered stents (for larger or anatomically difficult defects)
Endoscopic suturing devices

A 2025 network meta-analysis of RCTs (PMID: 40217342) found endoscopic interventions were associated with fewer respiratory complications and shorter hospital stays vs. open repair, but current consensus is that prompt surgical repair (laparoscopic or open) remains the gold standard. Endoscopic techniques are viable alternatives for small perforations or in patients where general anesthesia is contraindicated.

Summary Table

Method	Best Indication	Key Feature
Non-operative management	Small, contained perforation; stable patient	NPO + antibiotics + close monitoring
Primary suture closure	Most perforations; traumatic/iatrogenic gastric	Full-thickness closure ± Lembert layer
Graham omental patch	Duodenal ulcer; friable/necrotic edges	Omentum tied over perforation
Falciformopexy	No omentum available	Ligamentum teres used as patch
Wedge resection	Greater curve gastric; poor tissue quality	Stapled V-shaped excision
Pyloroplasty ± vagotomy	Pyloric perforation; refractory PUD	Transverse closure widening pylorus
Antrectomy + reconstruction	Refractory PUD; antral/pyloric perforation	Billroth I/II or Roux-en-Y
Laparoscopic repair	Most stable PPU patients	Less SSI, less pain vs. open
Endoscopic repair	Small perforations; poor surgical candidates	Clips or stents; emerging evidence

Key recent evidence:

Laparoscopic vs. open: equivalent outcomes with advantages for laparoscopy (PMID: 39361132, Ann R Coll Surg Engl 2025)
Endoscopic alternatives: viable for selected patients but surgery remains standard (PMID: 40217342, World J Emerg Surg 2025)
Barbed sutures for laparoscopic repair: reduce operative time without compromising safety (PMID: 41342296, Scand J Gastroenterol 2026)
