Feasibility of NOTES omental plug repair of perforated peptic ulcers: results from a clinical pilot trial.
BACKGROUND
Ulcer perforation carries up to a 30 % 1-year mortality rate. Intervention-related adverse events are among statistically significant predictors of 1-year mortality. A natural orifice transluminal endoscopic surgical (NOTES) approach may be less invasive and may decrease procedure-related adverse events by diminishing the so-called second hit, thus leading to decreased morbidity and mortality. We sought to assess the feasibility of an endoscopic transluminal omental plug technique in patients with perforated gastroduodenal ulcers under laparoscopic guidance.


METHODS
Patients with suspected acute gastroduodenal ulcer perforations were offered participation in this prospective pilot study. Closure of the perforation was attempted using the NOTES omental plug technique. Demographic, clinical, endoscopic, and radiographic data were abstracted, as were data for morbidity, mortality, and pilot data regarding quality of life (QOL).


RESULTS
From February 2010 through February 2012, a total of 17 patients presented to a tertiary care center with clinically suspected perforated ulcer. Of seven patients (mean age 79 years, range 64-89 years) who consented to the study, three underwent the study procedure. All patients had multiple comorbidities. Two patients presented with 4-6 mm perforated peptic ulcers and underwent successful laparoscopic-assisted NOTES omental and falciform ligament patch closure, respectively. Postoperative radiographic contrast studies showed no leak, and patients were discharged home on postoperative days 3 and 4. The third patient had undergone enterocutaneous fistula repair with herniorrhaphy 6 weeks before. Although a transluminal endoscopic approach was feasible, the omentum was under too much tension to be secured. This procedure was converted to an open omental patch repair. For all but one patient who provided consent, obtaining QOL data was feasible.


CONCLUSIONS
Initial results from a laparoscopic-assisted NOTES approach for closure of perforated peptic ulcers appear promising and enable swift recovery in selected patients. This is especially important in elderly and/or immunocompromised patients. Technical details and patient selection criteria continue to evolve.
