PurposeThe education of surgical trainees should be based on an accurate evaluation of their surgical skill levels. In our hospital, the Objective Structured Assessment of Technical Skills (OSATS) is used for this purpose. We conducted this study to demonstrate the validity and accuracy of the OSATS for assessing surgical skills in the operating room (OR) setting.MethodsBetween January, 2007 and December, 2010, the OSATS global rating scale was used to assess several operations in which surgical trainees participated. We assessed ten surgical trainees who participated as the main surgeon or first assistant, and studied the correlation between their postgraduate year and their OSATS score.ResultsThe median score of the global rating scale for each trainee improved with each year of experience. The median scores of all trainees in postgraduate years 3, 4, and 5 were significantly different (p < 0.001 for both the main surgeon and first assistant roles; Kruskal–Wallis test).ConclusionUsing the OSATS global rating scale to assess the surgical skills of trainees in the OR was feasible and effective.

This study demonstrated that TLDG has several advantages over LADG including smaller wounds, less invasiveness, and better feasibility of a secure ablation. The TLDG procedure yields safe anastomosis independently of the patient's constitution or the location of the cancer. Therefore, TLDG is considered to be a useful technique for patients with gastric cancer.

Abstract. In patients with stage IV gastric cancer, systemic chemotherapy is the key treatment. Combination chemotherapy (cis-diamminedichloride platinum plus S-1 and docetaxel plus S-1) results in long-term survival in clinical practice. In selected cases, additional (adjuvant) surgery may result in further longterm survival. This study aimed to evaluate the efficacy of adjuvant surgery following the response to chemotherapy for advanced gastric cancer. Based on response to chemotherapy, the indications for adjuvant surgery (surgery after the response to chemotherapy) are that resection is expected to be curative rather than palliative, provided that no other distant metastases occur. The study included 20 advanced gastric cancer patients who had undergone gastrectomies after the response to the combination chemotherapy of docetaxel and S-1, between September 2003 and December 2008 at Hiroshima University Hospital. At a median follow-up of 980 days, the median overall survival was 855 days. A 2-and 3-year survival was observed in 80 and 54.9% of patients, respectively, following macroscopic curative surgery. In the palliative group, the median overall survival was 510 days, but a 3-year survival was not observed. In the partial response group, the median overall survival was 865 days and a 3-year survival was observed in 37% of patients. One-year survival was not observed in the stable disease group. The patient survival in the partial response group was statistically more prolonged than in the stable disease group. The median overall survival in patients with liver metastasis was 865 days, while that in patients with peritoneal dissemination was 510 days. In conclusion, adjuvant surgery may be effective in gastric cancer patients diagnosed as stage IV by means of liver or distant lymph node metastasis, except in cases of peritoneal dissemination.

We developed a new technique for the retraction of the liver using a Penrose drain and a J-shaped retractor, which is both an easy and time-saving method that provides a good view during laparoscopic gastrectomy without damaging the liver.
