Laparoscopic versus open gastroplasty in esophagectomy for esophageal cancer: a comparative study

How best to approach esophagectomy is a controversial issue. In the last decade, the opportunity to use minimally invasive surgical methods for esophagectomy has been documented, but their real advantages over conventional surgery have yet to be clearly established. The aim of this study was to compare a series of patients who underwent laparoscopic esophagectomy with those who underwent open surgery to ascertain the feasibility, safety, and clinical advantages of the former surgical techniques. Between January 2002 and May 2004, 14 patients with cancer of the esophagus underwent laparoscopic esophagectomy and another 14 had conventional open esophagectomy. Their demographic features, and intraoperative and postoperative data were compared. The 2 groups were comparable in terms of age, American Society of Anesthesiologists score, and site of the neoplasm. The operating times were the same for transhiatal laparoscopic esophagectomy and conventional surgery, although using the thoraco-laparoscopic access took longer than the thoraco-laparotomic procedure (P<0.05). The hospital stay was shorter after laparoscopy (P<0.05). No differences emerged in terms of morbidity, mortality, number of transfusions, and time in the intensive care. The numbers of lymph nodes removed were comparable. In conclusion, it is feasible and safe to use a laparoscopic approach instead of open surgery for esophagectomy, but the former does not offer very significant clinical advantages in the postoperative stage. A shorter hospital stay seems to be the most significant finding. The minimally invasive procedure would seem to assure oncological radicality because it enables lymphadenectomy to be as thorough as in the conventional surgical approach.
