Aims: Reinforcement of the staple line is one of the most debated technical aspects concerning laparoscopic sleeve gastrectomy (LSG). Different buttressing methods have been proposed and demonstrated to be effective in reducing the incidence of staple line bleeding, although data concerning their effort on staple line leakage are not consistent. The aim of this study was to ascertain the technical feasibility and to report the preliminary outcomes of laparoscopic use of platelet-rich plasma (PRP) to reinforce the staple line during sleeve gastrectomy.
Patients and Methods: From March 2012 to May 2012, 20 patients were prospectively enrolled (10 females; mean age, 44.6 +/- 11 years; mean body mass index, 42.3 +/- 5.45 kg/m(2)). Type 2 diabetes mellitus was present in 4 patients, obstructive sleep apnea syndrome in 3, and hypertension in 6. LSG was performed using a 48-French bougie and gold cartridges; reinforcement of the staple lines with buttressed materials or oversewing the suture was performed excluding the last cranial cartridge. PRP was prepared by separating the platelets from autologous blood withdrawn on the same day of surgery, in order to obtain a membrane with cylindrical shape (2x5 cm) formed by fibrin and active platelets. The membrane is introduced through the 10-mm trocar and placed at the upper portion of the staple line. The overall cost for the preparation of PRP is about euro15.
Results: No intraoperative complications and conversions have been recorded during the surgical procedures. No deaths occurred. The mean operative time was 85 +/- 31 minutes, which was not significantly increased compared with the operative time of the surgeon's overall personal series (750 cases). At 12 months of follow-up the abdominal ultrasound was negative for collections, and upper contrast showed no images indicating gastric leaks. In no case did PRP induce symptoms of rejection, infection, or adverse events.
Conclusions: The use of PRP during LSG is feasible, does not increase significantly the operative time, does not require any special devices, and is cost effective. A larger cohort of patients is needed to ascertain the potential effectiveness of PRP in the prevention of postoperative staple line complications.
