Abstract

A 65-year-old man with cT1bN0M0 stage I middle thoracic esophageal cancer underwent subtotal esophagectomy and gastric tube reconstruction through the posterior mediastinal route after preoperative carbon-ion radiotherapy and chemotherapy in a clinical trial. Anastomotic leakage occurred, but it spontaneously improved. At six months after the operation, he was rehospitalized with a cough and dysphagia. An esophago-bronchiole fistula and stenosis of the gastric tube were observed. He first underwent stent placement in the gastric tube. Two weeks later, the syringeal epithelium was burned by argon plasma coagulation after stent removal. Endoscopic occlusion was then performed for the fistula with two guidewire-assisted silicone spigots. Two weeks later, he was discharged on an oral diet, and he has not developed recurrence of the fistula or cancer for three years. This is the first report of endoscopic occlusion with a guidewire-assisted silicone spigot through the esophagus.

Abstract

The use of minimally invasive surgery has become widely accepted in many gastrointestinal fields, even in patients with malignancy. However, performing laparoscopic resection for the treatment of hilar cholangiocarcinoma is still not universally accepted as an alternative approach to open surgery, and only a limited number of such procedures have been reported due to the difficulty of performing oncologic resection and the lack of consensus regarding the adequacy of this approach. Laparoscopy was initially limited to staging, biopsy and palliation. Recent technological developments and improvements in endoscopic procedures have greatly expanded the applications of laparoscopic liver resection and lymphadenectomy, and some reports have described the use of laparoscopic or robot-assisted laparoscopic resection for hilar cholangiocarcinoma as being feasible and safe in highly selected cases, with the ability to obtain an adequate surgical margin. However, the benefits of major laparoscopic surgery have yet to be conclusively proven, and carefully selecting patients is essential for successfully performing this procedure.
