BACKGROUND A direct comparison of open operation and video-assisted thoracoscopic surgery (VATS) for radical oesophagectomy has yet to be published. METHODS Medical records of 149 patients with oesophageal squamous cell carcinoma who underwent oesophagectomy and three-field lymphadenectomy were reviewed. Seventy-seven patients had the thoracic procedure(More)
Recent advances in surgical techniques have led to widespread acceptance of laparoscopic gastrectomy for gastric cancer. We performed distal gastrectomy with regional lymph node dissection in 235 patients with gastric cancer located in the middle and lower third of the stomach. In 171 cases, reconstruction was done using the Billroth I method(More)
Among the less invasive operations noted in recent years, laparoscopic gastrectomy for gastric cancer has become popular because of advances in surgical techniques. The authors performed laparoscopic gastrectomy with regional lymph node dissection for 612 cases of gastric malignancies between March 1998 and August 2006. The technique and results of(More)
Background: Thoracoscopic esophagectomy for esophageal cancer has been performed as an alternative to open surgery to reduce surgical trauma. However, its effect on pulmonary function, exercise tolerability, and quality of life is unknown. Methods: Fifty-one patients with esophageal cancer underwent thoracic esophagectomy with radical lymphadenectomy by(More)
Recently, a minimally invasive operation for gastric malignancies has been developed, and this laparoscopic operation is seen as a technique that will raise quality of life for patients. Previously, we reported this technique, as well as the results of a distal gastrectomy with regional lymph node dissection using hand-assisted laparoscopic surgery (HALS)(More)
As the laparoscopic operations for gastric cancer have increased, the intracorporeal reconstruction of the digestive tract has received attention because the procedure offers a good visual field regardless of the patient's figure. We performed laparoscopic gastrectomies with regional lymph node dissection on 586 gastric cancer patients between March 1998(More)
As the techniques of laparoscopic surgery have improved, various institutions have performed laparoscopic gastrectomies with regional lymph node dissection, as well as open surgery. Although alleviation of postoperative pain and prompt recovery have been reported in the literature, objective indexes of the minimal invasiveness of laparoscopic procedures are(More)
Background: The efficacy of thoracoscopic radical esophagectomy for cancer has yet to be established, mainly because previous reports have not included a sufficient number of cases. Methods: Seventy-five treatment-naive patients with esophageal cancer without contiguous spread underwent esophageal mobilization and extensive mediastinal lymphadenectomy(More)
BACKGROUND/AIMS Gastroduodenostomy (Billroth I) or gastrojejunostomy (Billroth II) after distal gastrectomy is associated with duodenogastric reflux and remnant gastritis. This study sought to determine which reconstructive procedure is least likely to cause remnant gastritis and to determine the correlation between duodenogastric reflux and remnant(More)
Billroth I and II reconstructions are commonly performed after distal gastrectomy. Both may cause duodenogastric and duodenogastro-esophageal reflux, conditions reported to have carcinogenetic potential. The aim of this study was to investigate which reconstructive procedure would most effectively prevent bile reflux into the gastric remnant and esophagus(More)
