A Novel Valvuloplastic Esophagogastrostomy Technique for Laparoscopic Transhiatal Lower Esophagectomy and Proximal Gastrectomy for Siewert Type II Esophagogastric Junction Carcinoma—the Tri Double-Flap Hybrid Method
We developed a novel technique for valvuloplastic esophagogastrostomy, named tri double-flap hybrid method (TDF). TDF is shown to be simple and useful for Siewert type II esophagogastric junction carcinoma.

Comparison of the intracorporeal triangular and delta-shaped anastomotic techniques in totally laparoscopic distal gastrectomy for gastric cancer: an analysis with propensity score matching
The delta-shaped anastomotic technique (Delta-SA) has been accepted as a standard reconstruction method in totally laparoscopic distal gastrectomy with Billroth I reconstruction (TLDG B-I). However, some anast...

Feasibility and Safety of a Novel Laparoscopic and Endoscopic Cooperative Surgery Technique for Superficial Duodenal Tumor Resection: How I Do It
Pancreatoduodenectomy is considered to be a very invasive treatment for early superficial duodenal tumors (SDTs), which have a lower risk of lymph node metastasis. Partial resection of the duodenum with endosc...

Article
The Safety and Feasibility of Single-Port Laparoscopic Gastrectomy for Advanced Gastric Cancer
Single-port laparoscopic surgery maximizes the advantages of laparoscopic surgery by reducing damage of the abdominal wall. However, no comparative studies have addressed its application to gastrectomy for adv...

Clinical Outcomes of Gastric Cancer Patients Who Underwent Proximal or Total Gastrectomy: A Propensity Score-Matched Analysis
Total gastrectomy (TG) and proximal gastrectomy (PG) are used to treat upper-third early gastric cancer. To date, no consensus has been reached regarding which procedure should be selected. The aim of this stu...

Open AccessImprovement of cisplatin-related renal dysfunction by synthetic ghrelin: a prospective randomised phase II trial
Ghrelin, a 28-amino acid peptide predominantly produced by the stomach, exerts powerful renal protective effects by increasing levels of insulin-like growth factor-1 (IGF-1). The aim of this study was to evalu...
