1.  Prospective randomized controlled trial (phase III) to comparing laparoscopic distal gastrectomy with open distal gastrectomy for gastric adenocarcinoma (KLASS 01) 
A randomized controlled trial to evaluate the long-term outcomes of laparoscopic distal gastrectomy for gastric cancer is currently ongoing in Korea. Patients with cT1N0M0-cT2aN0M0 (American Joint Committee on Cancer, 6th edition) distal gastric cancer were randomized to receive either laparoscopic or open distal gastrectomy. For surgical quality control, the surgeons participating in this trial had to have performed at least 50 cases each of laparoscopy-assisted distal gastrectomy and open distal gastrectomy and their institutions should have performed more than 80 cases each of both procedures each year. Fifteen surgeons from 12 institutions recruited 1,415 patients. The primary endpoint is overall survival. The secondary endpoints are disease-free survival, morbidity, mortality, quality of life, inflammatory and immune responses, and cost-effectiveness ( ID: NCT00452751).

2.  Robot-assisted distal gastrectomy for gastric cancer in a situs inversus totalis patient 
A 47-year-old man was referred to Seoul National University Bundang Hospital with an ulcerative lesion in the midbody of the stomach. Computed tomography revealed that he was a situs inversus totalis (SIT) patient. Robot-assisted distal gastrectomy with D1+β lymph node dissection and Billroth II anastomosis were performed. With the aid of robotic surgery, the surgeon didn't need to change his position and could perform the surgery without any confusion resulting from the patient's reversed anatomy. The operation took 300 minutes, with no intraoperative complications. The postoperative course was uneventful, and the patient was discharged on postoperative day 8. The final pathologic report was pT3N3a by American Joint Committee on Cancer 7th tumor-node-metastasis staging. We successfully performed robot-assisted distal gastrectomy for gastric cancer in a SIT patient. We believe that this is the first case of robotic surgery reported in a SIT patient with gastric cancer.

3.  Local tissue reaction after injection of contrast media on gastric wall of mouse: experimental study for application of contrast media to computed tomography lymphography 
Computed tomography (CT) lymphography is a simple technique of sentinel node navigation but tissue reaction after injection of contrast media has not been reported yet.
Ninety mice used in this study were divided into three groups: lipiodol, iopamidol, and normal saline. The test compounds were given by submucosal injection to the gastric wall of anesthetized mice. The specimens were subjected to histopathological examination.
The mean grades of acute inflammatory response after iopamidol and lipiodol injection were significantly higher than control group. However, there was no significant difference between iopamidol and lipiodol injection. The mean grade of chronic inflammatory response and fibrosis showed no differences between groups. The presence or absence of fibrinoid necrosis and mesothelial hyperplasia showed no statistical differences at each time point between groups. The foam cell, which is similar to human signet ring cell carcinoma, were not identified in normal saline and iopamidol group, but were detected by postoperative day 7 in lipiodol group.
We conclude that iopamidol and lipiodol when used as a contrast media of CT lymphography is an available material for preoperative sentinel node navigation surgery for gastric cancer with an acceptable incidence of pathological alterations in a mouse model. Our results are potentially useful to clinical (human) application.

4.  A case of anaphylactic shock attributed to latex allergy during gastric cancer surgery 
Journal of the Korean Surgical Society  2011;81(Suppl 1):S30-S33.
Latex allergy is a known cause of allergic contact dermatitis. It produces mild symptoms, including skin rash and itching, which usually subside in a few days. However, latex allergy can also induce anaphylaxis, a severe type I hypersensitivity reaction that can cause urticaria, angioedema, hypotension, tachycardia, and bronchospasm. We report a case of anaphylactic shock during gastric cancer surgery in a patient with no previous allergic history. Surgery was suspended when hypotension, tachycardia, and wheezing developed. A thorough workup revealed that the patient had a latex allergy. The patient subsequently underwent curative gastrectomy performed with latex-free procedures.

5.  Laparoscopy-assisted distal gastrectomy for gastric cancer after liver transplantation 
Journal of the Korean Surgical Society  2011;80(Suppl 1):S1-S5.
A case report described a 72-year-old man with a history of a deceased-donor liver transplantation (due to hepatitis B-associated end-stage liver cirrhosis) performed in 1994. The patient was diagnosed with renal cell carcinoma and pulmonary metastasis in 1997 and was successfully treated with radiofrequency ablation and thoracoscopic superior segmentectomy. There was no evidence of newly diagnosed metastatic lesions or recurrence until the 19th post-operative month. Gastric cancer was identified by endoscopy during a routine follow-up examination; the pre-pyloric antral lesion measured 1.5 cm in size and was histologically well-differentiated and confined to the submucosal layers on endoscopic ultrasound. Laparoscopic gastrectomy and lymph node dissection (D1 + β) was successfully performed in March 2009, and the patient was discharged on the 5th post-operative day without complications. This suggests that laparoscopic surgery is one of the feasible methods for resection of gastric cancer in liver transplant patients.
