Revisional Surgery from Vertical Banded Gastroplasty to Roux-en-Y Gastric Bypass with Gastric Resection.

Abstract

Introduction: Vertical banded gastroplasty (VBG) was a common bariatric procedure by laparotomy and or at the beginning of the laparoscopy, but nowadays it is almost an abandoned procedure. However, the young generation of bariatric surgeons should be aware about this procedure especially for revisional cases. Roux-en-Y gastric bypass (RYGB) is considered the procedure of choice for the revision of VBG. Materials and Methods: The evolution of revisional surgery to RYGB has known several technical steps. At the beginning, the procedure was performed with no gastric resection. Then a limited resection of the ancient staple line along with the fibrous tissue under the previous band or mesh was performed. The purpose of this article is to describe a simplified operative technique to simultaneously resect the ancient staple line and the calibration band. Results: After the initial viscrerolysis, an attempt to distinguish the course of the ancient section line of the stomach during the VBG is done. The dissection can become extremely challenging, with too much fibrosis and nonanatomical planes of dissection. At this point, we counsel to abandon the anterior direct dissection of the upper part of the stomach and to switch to a posterior dissection with the approach of greater curvature. Driven by the potential advantages (no risk of mucocele or gastrogastric fistula), for the past several years, we have changed the technique from resecting only the ancient staple line to perform a partial gastrectomy. The gastrectomy is larger and includes the complete resection of the gastric fundus, ancient staple line, the region with the mesh inside, and part of the gastric body. Once the stomach is extracted, the subsequent steps are similar to those of a primary RYGB. Conclusion: The procedure of choice for the revision of VBG is represented by RYGBP. Associating an atypical gastrectomy of the previous staple line with the region of mesh migration is a safe approach, eliminating the risk of mucocele.
