Prospective study of lymph node imaging of twenty stomach cancer cases with dissected lymph nodes being injected into the submucosa layer of stomach under surgical field was done. Total dose of 5 mci in 5 cc of volume was injected along the multiple sites of the lesser and greater curvature of stomach and collected lymph nodes within 2 hour of surgical time were placed under gamma camera and lymph node imagings were obtained. Pathological invasion of tumor and correlation of cold defect or hot uptake was compared each other. Tumor invasion of nodes revealed cold defect area which was correlated well with the pathological specimen. Correlation rate was 84.6%. We are planning to extend these procedures and trying endoscopic injection of positive imgaing agents such as Ga-73-3 Ig 2 alpha in future.

Purpose: The aim of this study was to evaluate the effectiveness of our retraction method for achieving a good operative field for the adequate lymph node dissection during laparoscopic gastrectomy in view of short term surgical outcome. Materials and Methods: This study prospectively enrolled 19 patients who underwent laparoscopic gastrectomy for early gastric cancer. The procedure was simply performed by putting the laparoscopic sigle suture in the phrenoesophageal ligament, and then the string was pulling and tying over the sternum. Surgical outcomes of these patients were evaluated. Results: Under V-shaped liver retraction, the mean operating time and mean number of retrieved lymph nodes was 166.3 minute and 31.37, respectively. And the results were satisfactory compared to open or conventional laparoscopic gastric surgery. Conclusions: V-shaped liver retraction requires no extra port or assistant's hands, and prevents additional injury to any intra-abdominal organ. And this method can easily, efficiently and safely enable to achieve a good operative field for the lymph node dissection near the lesser curvature of the stomach.

Purpose: To evaluate the status of number 3b lymph node (LN) station in patients with adenocarcinoma of the esophagogastric junction (AEG) and to investigate the optimal indications for radical proximal gastrectomy (PG) for AEG. Materials and Methods: Data of 51 patients with clinically advanced Siewert types II and III AEG who underwent total gastrectomy (TG) between April 2010 and July 2017 were reviewed. The proportion of metastatic LNs at each LN station was examined. Number 3 LN station was separately classified into number 3a and number 3b. The risk factors for number 3b LN metastasis and the clinicopathological features of number 3b-positive AEG patients were investigated. Results: The incidences of LN metastasis were the highest in number 1 (47.1%), followed by number 2 (23.5%), number 3a (39.2%), and number 7 (23.5%) LN stations. LN metastasis in number 3b LN station was detected in 4 patients (7.8%). A gastric invasion length of more than 40 mm was a significant risk factor for number 3b LN metastasis. All 4 patients with number 3b-positive AEG had advanced cancer with a gastric invasion length of more than 40 mm. The 5-year survival rate of patients with a gastric invasion length of more than 40 mm was 50.0%. Conclusions: Radical PG may be indicated for patients with AEG with gastric invasion length of less than 40 mm.

위암의 한 아형인 간양 선암은 조직학적으로 간세포암종과 형태학적으로 유사하며 알파태아단백 생산을 특징으로 한다. 간양 선암의 또 하나의 특징은 간과 림프절로의 조기 전이를 함으로써 불량한 예후를 갖는다는 것이다. 저자들은 간전이를 동반한 위의 간양 선암 1예를 보고하고자 한다. 소화불량을 주소로 내원한 52세 남자 환자는 위내시경 검사상 Borrmann 제2형 병변이 위암이 의심되었다. 환자의 혈청 알파태아단백은 123 ng/ml로 증가되어 있었다. 근치적 위아전절제술과 간우엽절제술을 시행하였고 조직학적 소견상 위의 병변은 점막하층에 국한된 간양 선암이었으며 간의 병변은 위로부터 전이된 선암이었다. 결국 환자는 위암 4기(T1N1M1)로분류되었다. 위의 간양 선암은 조기병변에서도 불량한 예후군으로 분류될 수 있다.
