    Abstract:
    The aim of this study was to evaluate the worldwide trends in surgical techniques for esophageal cancer surgery by comparing it to our survey from 2007. In addition, new questions were added for gastroesophageal junction (GEJ) cancer. An international survey on surgery of esophageal and GEJ cancer was performed among surgical members of the International Society for Diseases of the Esophagus, the World Organization for Specialized Studies on Disease of the Esophagus, the International Gastric Cancer Association. Also, surgeons from personal networks were contacted. The participants filled out a web based questionnaire about surgical strategies for esophageal and gastroesophageal cancer. The overall response rate was 478/1147 (42%). The respondents represented 49 different countries and 6 different continents. The annual cumulative number of esophageal and gastric resections per surgeon was low (≤11) in 11%, medium (11-21) in 17%, and high (≥21) in 72% of respondents. In a subgroup analysis of esophageal surgeons the number of high volume surgeons increased from 45 to 54% over the past 7 years. The preferred lymph node dissection was two-field in 86%. A gastric conduit was the preferred method of reconstruction in 95%. In 2014, the preferred approach to esophagectomy was minimally invasive transthoracic in 43%, compared with 14% in 2007. In minimally invasive transthoracic esophagectomy the cervical anastomosis was favored in 54% of respondents in 2014 compared with 87% in 2007. The preferred technique of construction of the cervical anastomosis was hand-sewn in 64% and stapled in 36%, whereas the thoracic anastomosis was stapled in 77% and hand-sewn in 23%. The preferred surgical approach for Siewert type 1 tumors (5-1 cm proximal of the GEJ) was esophagectomy in 93% of respondents, whereas 6% favored gastrectomy and 3% combined a distal esophagectomy with a proximal gastrectomy. For Siewert type 2 tumors (1-2 cm from the GEJ) an extended gastrectomy was favored by 66% of respondents, followed by esophagectomy in 27% and total gastrectomy in 7%. Siewert type 3 tumors (2-5 cm distal of the GEJ) were preferably treated with gastrectomy in 90% of respondents, esophagectomy in 6%, and extended gastrectomy in 4%. The preferred curative surgical treatment of esophageal cancer is minimally invasive transthoracic esophagectomy with a two-field lymph node dissection and gastric conduit reconstruction. A strong worldwide trend toward minimally invasive surgery is observed. The preferred surgical treatment of GEJ tumors is esophagectomy for Siewert type 1 tumors and gastrectomy for Siewert type 3 tumors. The majority of surgeons favor an extended gastrectomy for Siewert type 2 tumors.
