BACKGROUND Construction of an esophagojejunostomy is a major concern in totally laparoscopic total gastrectomy (TLTG). Use of a circular stapler can be technically challenging in laparoscopic procedures. We aimed to introduce our modified techniques and to assess the early outcomes following TLTG with side-to-side esophagojejunostomy using a linear stapler(More)
Endoscopic submucosal dissection (ESD) has become accepted as the standard treatment for early gastric cancer. However, comparative outcomes of ESD and surgery have not been evaluated for adenocarcinoma in the esophagogastric junction (EGJ). We investigated the long-term outcomes of ESD compared with those of surgery for adenocarcinoma in the EGJ. Patients(More)
BACKGROUND & AIMS Early-onset gastric cancer, which develops in patients younger than most gastric cancers, is usually detected at advanced stages, has diffuse histologic features, and occurs more frequently in women. We investigated somatic genomic alterations associated with the unique characteristics of sporadic diffuse gastric cancers (DGCs) from(More)
This study was conducted to determine the recommended dose (RD) of intraperitoneal docetaxel (ID) in combination with systemic capecitabine and cisplatin (XP) and to evaluate its efficacy and safety at the RD in advanced gastric cancer (AGC) patients with peritoneal metastasis. AGC patients with peritoneal metastasis received XP ID, which consists of 937.5(More)
BACKGROUND Efficient retraction of the left lobe of the liver is mandatory for laparoscopic gastric surgery because of the lesser curvature of the stomach, the gastroesophageal junction, and the gastrohepatic ligaments that are covered by the left lobe. We attempted to introduce our simple and safe method for lifting up the liver by suturing the pars(More)
Construction of an esophagojejunostomy is still a challenging procedure in totally laparoscopic total gastrectomy (TLTG), and there is no standard anastomosing method. The aims of this study were to describe our TLTG with the overlap method using a linear stapler and report surgical outcomes. From January 2015 to April 2016, 50 patients underwent TLTG using(More)
Tumor differentiation is a major determinant of endoscopic resection in mucosal gastric cancers, and the treatment decision is usually based on a preoperative endoscopic biopsy. However, in a proportion of patients, the pathologic assessment of differentiation differs between the endoscopic biopsy and postgastrectomy specimen. This discrepancy is important(More)
To evaluate the feasibility of post-operative CT gastrography for volumetry of the remnant stomach in gastric cancer patients treated with distal gastrectomy. CT gastrography was performed with oral administration of effervescent granules in 35 gastric cancer patients who underwent distal gastrectomy. Two readers independently rated the degree of gastric(More)
Posttransplant malignancy is one of the major causes inhibiting long-term graft survival. Gastric adenocarcinoma is the most common malignancy in Korea and occurs more frequently in renal transplant recipients compared to that in Western countries. We aimed to analyze the clinical features of the post-renal-transplant gastric cancer and assess factors that(More)
BACKGROUND Optimal extent of surgery remains controversial in types 2 and 3 adenocarcinoma of esophagogastric junction (AEG). We aimed to determine whether the extended procedure including mediastinal lymphadenectomy is essential in all patients with AEG by comparing prognosis and recurrence of proximal gastric adenocarcinoma based on total gastrectomy with(More)
