BACKGROUND Most studies about complication after gastric cancer surgery have been performed without consideration of the severity of each complication. The purposes of this study were to prospectively analyze all postgastrectomy complications according to severity using Clavien-Dindo classification and to identify risk factors related to postoperative(More)
PURPOSE This study aimed to analyze the effect of screening by using endoscopy on the diagnosis and treatment of gastric cancer. MATERIALS AND METHODS The clinicopathologic characteristics of gastric cancer were compared in individuals who underwent an endoscopy because of symptoms (non-screening group) or for screening purposes (screening group). The(More)
PURPOSE This study evaluated the functional and oncological outcomes of proximal gastrectomy (PG) in comparison with total gastrectomy (TG) for upper-third early gastric cancer (EGC). MATERIALS AND METHODS The medical records of upper-third EGC patients who had undergone PG (n=192) or TG (n=157) were reviewed. The PG group was further subdivided into(More)
BACKGROUND This study aimed to compare the short- and long-term results of minimally invasive surgery (MIS) and open surgery for primary early gastric cancer (EGC) at a single high-volume institution. METHODS The clinicopathologic and survival data of primary gastric cancer patients who underwent a minimally invasive radical gastrectomy at Seoul National(More)
We report our experience with two cases of situs inversus totalis, both involving patients diagnosed with gastric cancer. These were a 52-year-old male with a preoperative staging of cT1bN0M0 and a 68-year-old male with a staging of cT2N0M0, both of whom underwent surgery. The former was found to have vascular anomalies in the preoperative computed(More)
PURPOSE This study aimed to evaluate the value of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels to detect gastric cancer recurrence. MATERIALS AND METHODS We retrospectively reviewed 154 patients who developed recurrence within 2 years after curative gastric cancer surgery and analyzed the relationship between(More)
Controversy surrounds adjuvant chemotherapy (CTx) for T3N0M0 and T1N2M0 in the American Joint Committee on Cancer (AJCC) 7th edition stage IIA gastric cancer patients. The purpose of this study was to evaluate the benefit of adjuvant CTx for stage IIA cancer, including T3N0M0 and T1N2M0. A total of 630 patients with stage IIA cancer who underwent a radical(More)
Previous studies regarding ultrasonically activated shears (UAS) were performed without controlled surgical procedures or consideration of potential thermal injury due to high temperature of active blade of UAS. The purpose of this study was to evaluate the efficacy and safety of UAS through a comparison with conventional monopolar electrocautery (CME) in(More)
We propose and demonstrate bend-insensitive fibers equipped with higher-order mode strippers. The mode stripper is realized by filling a section of air holes with epoxy to attenuate any higher-order modes that are excited at fiber junctions and are confined by the air holes surrounding the core. We found that the higher-order modes are well suppressed with(More)
OBJECTIVE To evaluate risk factors for lymph node (LN) metastasis in mucosal gastric cancer, particularly the effect of cellular differentiation, and implications for the indication of endoscopic submucosal dissection (ESD). SUMMARY BACKGROUND DATA The indication of ESD has been expanded to undifferentiated-type (UD-type) gastric cancer despite risk of LN(More)
