Abstract

Background

Traditional approach for surgical management of mature pancreatic pseudocysts is by internal surgical drainage. Endoscopic drainage procedures have also been described. We describe Natural Orifice Translumenal Endoscopic Surgery (NOTES®) stapled cystgastrostomy as a less invasive surgical procedure.

Study design

Case series.

Methods

NOTES® cystgastrostomy was performed in six patients with mature pseudocysts from June 2007 to July 2009 under institutional review board (IRB) protocol. The size of the pseudocysts varied from 8 to 23 cm, and all of the pseudocysts were considered complex pseudocysts. The operative team included two general surgeons and a gastroenterologist. The procedure included endoscopic ultrasound (EUS)-guided puncture of the stomach just below the gastroesophageal (GE) junction to gain access to the pseudocyst, guidewire placement, and then dilatation with a balloon to 18–20 mm. Endoscopic necrosectomy and debridement were performed when possible, followed by transoral surgical anastomosis under endoscopic visualization with the SurgAssist™ SLC 55 (Power Medical Interventions, Langhorne, PA) 4.8-mm stapler. Anastomotic length varied from 5.5 to 8 cm. In one patient, diagnostic laparoscopy was performed after the procedure due to inadvertent pneumoperitoneum; no leak or perforation was identified.

Results

Length of stay varied between 2 and 14 days. All patients had routine esophagogastroduodenoscopy (EGD) at 1 and 6 weeks postoperatively to evaluate patency; computed tomography (CT) scan was done at 2–3 months to demonstrate resolution of the pseudocyst. All patients had significant decrease in pseudocyst size with patent anastomosis on postoperative EGD, although one patient required endoscopic anastomotic dilatation due to continued symptoms 6 weeks after the operation. Her pseudocyst completely resolved 4 months postoperatively. An additional patient required subsequent distal pancreatectomy due to recurrent symptoms of chronic pancreatitis.

Conclusion

NOTES® cystgastrostomy is comparable to previously described surgical approaches, yet is as minimally invasive as endoscopic drainage procedures previously described for management of pseudocysts. It is less invasive than laparoscopic or open cystgastrostomy, yet provides definitive treatment.
