Objectives: The purpose of this study was to evaluate the risk factors that influence the difficulty of performing laparoscopic spleen-preserving splenic hilar lymph node dissection (SHLND) for gastric cancer and to establish a simple and effective scoring system to predict the surgical difficulty preoperatively.
Methods: Between January 2011 and December 2013, we prospectively collected and retrospectively analyzed the medical records of 317 patients with upper- or middle-third gastric cancer who underwent laparoscopic spleen-preserving SHLND. Univariate and multivariate analyses were performed to determine the independent predictors for surgical difficulty based on the operation time during spleen-preserving SHLND.
Background: The oncologic outcomes of laparoscopy-assisted gastrectomy (LAG) for the treatment of patients with local advanced gastric cancer (AGC) have not been evaluated. This study aimed to validate the oncologic efficacy of LAG for AGC.
Methods: The data from 539 patients who underwent LAG and 539 patients treated with open gastrectomy (OG) were selected using the propensity score-matching method from a database prospectively constructed between 2005 and 2011.
Background: A scoring system allows risk stratification of morbidity might be helpful for selecting risk-adapted interventions to improve surgical safety. Few studies have been designed to develop scoring systems to predict SSIs after laparoscopic gastrectomy for gastric cancer.
Methods: We analyzed the records of 2364 patients who underwent laparoscopic gastrectomy for gastric cancer.
This study investigated anatomical variations in the confluence types of the right gastroepiploic vein (RGEV) to improve knowledge regarding no. 6 lymphadenectomy for laparoscopic gastrectomy.The RGEV drainage patterns of 144 patients who were diagnosed with gastric cancer and underwent laparoscopic distal gastrectomy at our department from July 2010 to June 2011 were prospectively collected and retrospectively analyzed, and we compared the impact of different drainage patterns on no.

The aim of the present study was to clarify the value of LTG in the elderly using a propensity score matching method.
Methods: We prospectively collected data from 675 elderly gastric cancer patients who underwent total gastrectomies at our institution between January 2002 and February 2012.
The common hepatic artery (CHA) is an important blood vessel that must be vascularized during D2 lymphadenectomies for gastric cancer. When the CHA is absent, the risk of vascular injury increases.To explore the anatomic classification of CHA absence and its application value in laparoscopic radical resections for gastric cancer.

Methods: The clinical anatomy data of 317 patients with upper- or middle-third gastric cancer who underwent LTGSPL in our hospital from January 2011 to December 2013 were collected. The patients were divided into two groups (concentrated group vs distributed group) according to the distance between the splenic artery's furcation and the splenic hilar region.
Objective: To validate the efficacy and safety of laparoscopic total gastrectomy (LTG) for advanced gastric cancer (AGC).
Background: Laparoscopic distal gastrectomy (LDG) in the treatment of patients with local AGC is becoming increasingly popular, and there have been several multicenter randomized controlled trials focused on this treatment. However, few reports on the procedure of LTG for AGC exist.
Background: Laparoscopic spleen-preserving total gastrectomy (LSPTG) for gastric cancer is only performed at a few specialized institutions and carries the risk of major perioperative complications (MPCs) that may require reoperation and impair recovery. However, the predictors of such events remain largely unknown.
Methods: Prospectively collected data from 325 consecutive patients undergoing LSPTG at a single institution from June 2011 to February 2014 were analyzed to determine the preoperative factors that correlated with MPCs.
Laparoscopic gastrectomy with D2 lymph node (LN) dissection has not yet been widely adopted for advanced gastric cancer because it is technically complicated. Due to the high suprapancreatic lymph nodes metastasis rate (LMR) and the various vascular anatomies, the suprapancreatic LN dissection is a crucial and demanding procedure for radical resection of gastric cancer.To explore the anatomical basis of the proximal splenic artery (SA) approach for laparoscopic suprapancreatic LN dissection and its application in advanced gastric cancer.

Purpose: Tumor stem cell surface marker CD44v6, a member of the CD44 protein family, is causally involved in the metastasis of cancer. Little is known about the functions of CD44v6 in gastric cancer. The aim of this study was to evaluate the prognostic value of CD44v6 and investigate its functional roles.

Methods: A total of 1366 consecutive gastric cancer patients who underwent LAG from January 2008 to June 2011 were enrolled in this study. We analyzed the patients based on the presence or absence of SVCA.
Background/aims: Although the XELOX regimen has been recommended as first-line adjuvant chemotherapy for advanced gastric cancer (AGC), its role in a neoadjuvant setting is not well established. Therefore, we aimed to assess the clinical effect of XELOX neoadjuvant chemotherapy on AGC when combined with laparoscopic surgery.
Methodology: We compared the effects of perioperative XELOX (neoadjuvant chemotherapy group, NCG) with the effects of adjuvant XELOX (direct surgical group, DSG) in patients with locally AGC.
Background: Laparoscopic gastrectomy (LG) for gastric cancer has increased in popularity due to advances in surgical techniques. The aim of this study is to validate the efficacy and safety of laparoscopic gastrectomy for gastric cancer compared with open gastrectomy (OG).
Methods: The study comprised 3,580 patients who were treated with curative intent either by laparoscopic gastrectomy (2,041 patients) or open gastrectomy (1,539 patents) between January 2005 and October 2013.

View Article and Find Full Text PDFBackground: The 7th UICC N stage may be unsuitable for remnant gastric cancer (RGC) because the original disease and previous operation usually cause abnormal lymphatic drainage. However, the prognostic significance of the current TNM staging system in RGC has not been studied.
Methods: Prospective data from 153 RGC patients who underwent curative gastrectomy from Jan 1995 to Aug 2009 were reviewed.
miR-183, a member of an evolutionarily conserved miRNA cluster (miR-96, miR-182, and miR-183), has been demonstrated to act as both a tumor suppressor and oncogene in various type of human cancer. However, the biological role of miR-183 in gastric cancer (GC) still remains unclear. In the present study, miR-183 expression was significantly decreased in gastric cancer tissues compared with its' adjacent normal tissues, and down-regulation of miR-183 was significantly associated with lymph node metastasis and pathological TNM stage.

Methods: We performed a case-control study enrolling 63 patients with distal gastric cancer (GC) undergoing TLDG with a DSG from January 2013 to June 2013. Twenty-two patients underwent a conventional DSG (Con-Group), whereas the other 41 patients underwent a modified version of the DSG (Mod-Group).
Background: The prognostic importance of tumor size in gastric cancer is unclear. This study investigated whether the inclusion of tumor size could improve prognostic accuracy in node-negative gastric cancer.
Methods: Clinical and pathological data of 492 patients with node-negative gastric cancer who underwent radical surgery in our department from January 1995 to December 2008 were analyzed.
Aim: To investigate whether computed tomography with 3D imaging (3DCT) can reduce the risks associated with laparoscopic surgery.
Methods: We performed a retrospective case-control study evaluating the efficacy of preoperative 3DCT of the splenic vascular anatomy on surgical outcomes in patients undergoing laparoscopic spleen-preserving splenic hilar lymph node (LN) dissection for upper- or middle-third gastric cancer. The clinical records of 312 patients with upper- or middle-third gastric cancer who underwent laparoscopic total gastrectomy with spleen-preserving splenic lymph node dissection in our hospital from January 2010 to June 2013 were collected, and the patients were divided into two groups (group 3DCT vs group NO-3DCT) depending on whether they underwent 3DCT or not.
Background: Laparoscopic spleen-preserving Splenic hilar lymphadenectomy (LSPL) is required in laparoscopy-assisted total gastrectomy for advanced proximal gastric cancer. However, it is considerably difficult and risk in clinical practice. Thus, we explore the application of LSPL performed by following the perigastric fascias and the intrafascial space in D2 radical gastrectomy for advanced upper-third gastric cancer.
