title: Outcomes of laparoscopic-assisted transhiatal esophagectomy for adenocarcinoma of the esophagus and esophago-gastric junction.
abstract: Esophagectomy is associated with substantial morbidity and mortality, yet it is the only modality that offers the possibility of cure for esophageal and gastroesophageal junction (E-GEJ) adenocarcinoma. Several minimally invasive techniques have been developed to decrease the morbidity of the operation, but to date, the results have not led to its wide adoption in part due to their complexity. We developed a technique of laparoscopic-assisted transhiatal esophagectomy (LA-THE) with the idea of preserving some of the advantages of the minimally invasive approach while eliminating the degree of complexity and the time required to complete the operation solely using laparoscopy. The course of all patients who underwent LA-THE for E-GEJ adenocarcinoma at the University of Washington Medical Center was determined by analysis of all hospital records to determine perioperative variables, complications, and survival. Patients were also given a follow-up survey in order to assess long-term health-related quality of life (Gastrointestinal Quality of Life Index or GIQLI). Seventy-two patients underwent LA-THE between 1995 and 2007. Median age was 64 years (range, 42-83 years), and the median body mass index was 28 (range 17-35). Twenty-eight tumors (39%) were categorized as Siewert I, 41 (57%) as Siewert II, and 3 (4%) as Siewert III. Median operative time was 299min (range, 212-700min). All the resections were R-0. The median number of lymph nodes harvested was 11 (range, 2-32). Using the Dindo-Clavien classification of surgical complication, we had a total of 48 postoperative complications in 37 patients: 26 (53%) grade I, 20 (41%) grade II, 1 (2%) grade IIIb, 1 (2%) grade IVb, and 1 (2%) grade V complications. Median length of hospital stay was 9 days (range, 7-58 days). One patient (1.4%) died within 30 days. Overall, 3- and 5-year survival (calculated Kaplan-Meier) was 68% and 63%, respectively. Forty-nine patients (90% of those still alive) answered the GIQLI survey. Median follow-up was 26 months (range, 6-144 months). The mean GIQLI score was 108 (range, 74-138) from a maximum possible value of 144. Our study shows that LA-THE is feasible, safe, and effective in the treatment of adenocarcinoma of the esophagus and GEJ and should probably be considered an alternative to open esophagectomy and other minimally invasive techniques in the treatment of this disease.
