The Influences of Long Periods of Pneumoperitoneum and Head up Position on the Variation of Heart-rate...

Stomach Cancer

Sympathetic activity could be increased during robot-assisted laparoscopic gastrectomy, which is performed in a head up position under CO2 pneumoperitoneum. Stimulation of the sympathetic nervous system prolongs the QT interval and can increases the susceptibility to life threatening cardiac arrhythmias. Thus the investigators decided to evaluate the heart-rate corrected QT interval (QTc interval) during robotic-assisted laparoscopic gastrectomy.

NBI for Identifying Resection Margin Status in Gastric Cancer

Gastric Cancer

As the proportion of early gastric cancer has been steadily increased in Korea, so has function-preserving surgery. The function preserving surgery is characterized by the minimized extent of gastrectomy, so this implies that bilateral margins are getting shorter than those of standard gastrectomies. Currently, there is only one way to identify resection margin status in gastric cancer, 'frozen biopsy'. However, it is labor-intensive and time-consuming procedure. In addition, the results rely on the pathologist's expertise, thereby it showed limitation of its accuracy; high false negative rate of signet ring cell carcinoma was reported in a previous study. Recently, many studies on magnifying endoscopy with narrow band imaging(NBI) demonstrated that this emerging technique is useful to identify the gastric tumor margin more clearly in vivo, compared with conventional indigocarmine chromoendoscopy. So it was hypothesized that NBI may allow reliable delineation of tumor and identification of resection margin status in the specimen after gastrectomy for gastric cancer.

Volatile Markers in Digestive Cancer

Colorectal CancerColorectal Adenoma7 more

The study is aimed to determine the potential of volatile marker testing for identification of gastrointestinal cancers (in particular - colorectal and gastric cancers), the related precancerous lesions in the stomach and colon. The study will be addressing the role of confounding factors, including lifestyle factors, diet, smoking as well as addressing the potential role of microbiota in the composition of exhaled volatile markers.

Lymph Node Staging System With a Novel Concept for Gastric Cancer: a Hybrid Type of Topographic...

Gastrectomy for Gastric Cancer

For staging the status of lymph node metastasis in gastric cancer, typographic based staging system was applied until last decade, especially in Eastern countries. However the old typographic lymph node staging system in gastric cancer was too complicated and less accurate for predicting the prognosis. Now the numeric based lymph node staging system is used in both East and West, but it include problems: no information on the anatomical extent of the disease, preoperative lymph node staging is nearly impossible, failure to provide an appropriate treatment plan, cannot represent the extent of lymph node dissection. We designed simple and specifically representing the anatomic extent of the disease for staging the status of lymph node in gastric cancer. Thus we compared its prognostic performance of this new staging system with those of the current TNM 7th edition of AJCC/UICC.

Study on Laparoscopic D2 Lymphadenectomy Plus Complete Mesogastrium Excision(D2+CME)for Advanced...

Gastric Cancer

Radical gastrectomy for gastric cancer with D2 lymph node dissection has been widely applied in advanced gastric cancer. However,for most patients,tumor local-regional recurrence has been proven unavoidable. Recently, many clinical studies have proved that some cancer cells and cancer nodes exist in the mesogastrium which can be hardly removed by conventional radical gastrectomy with D2 lymphadenectomy. It is suggested that Complete mesogastrium excision (CME) is imperative and should be added to D2 lymphadenectomy in order to reduce the risk of local recurrence. Thus, the comparison of short-term and long-term outcome between laparoscopic D2 lymphadenectomy plus complete mesogastrium excision and conventional laparoscopic D2 lymphadenectomy for locally advanced gastric cancer based on a well designed randomized controlled trial is needed.

CT Perfusion Changes in GI Cancer During Adenosine Vasodilation Test

Esophageal CancerGastric Cancer

The aim of this study was to investigate changes in abdominal tissue perfusion during adenosine vasodilation. Our hypotheses were that CT perfusion measurements are altered by changes in the circulatory system mediated by adenosine, and a more differentiated assessment of the circulatory capacity of abdominal tumours could be achieved by sequential rest and adenosine vasodilation CT perfusion measurements.
