Laparoscopic posterior truncal vagotomy and anterior seromyotomy: a porcine model.
A training technique for posterior truncal vagotomy and an anterior seromyotomy in the anesthetized pig is described. The first of five procedures was performed open in a conventional method. All succeeding procedures were performed after the establishment of a pneumoperitoneum with CO2 insufflation and the placement of two 10 mm trocars and three 5-mm trocars. A 45 degree camera and monopolar electrocautery were used during the video laparoscopic procedure. After completion of the procedure, the pigs were opened to closely inspect the surgery performed. Though there are some minor anatomic differences between porcine and human anatomy, the pig is an excellent model for gaining technical experience in the performance of a posterior truncal vagotomy and anterior seromyotomy.
