1.  Is Laparoscopy-assisted Radical Gastrectomy Safe in Patients with Child-Pugh Class A Cirrhosis? 
Journal of Gastric Cancer  2013;13(4):207-213.
Purpose
We investigated early postoperative morbidity and mortality in patients with liver cirrhosis who had undergone radical gastrectomy for gastric cancer.
Materials and Methods
We retrospectively reviewed the medical records of 41 patients who underwent radical gastrectomy at the Chonnam National University Hwasun Hospital (Hwasun-gun, Korea) between August 2004 and June 2009. There were few patients with Child-Pugh class B or C; therefore, we restricted patient selection to those with Child-Pugh class A.
Results
Postoperative complications were observed in 22 (53.7%) patients. The most common complications were ascites (46.3%), postoperative hemorrhage (22.0%) and wound infection (12.2%). Intra-abdominal abscess developed in one (2.4%) patient who had undergone open gastrectomy. Massive ascites occurred in 4 (9.8%) patients. Of the patients who underwent open gastrectomy, nine (21.9%) patients required blood transfusions as a result of postoperative hemorrhage. However, most of these patients had advanced gastric cancer. In contrast, most patients who underwent laparoscopic gastrectomy had early stage gastric cancer, and when the confounding effect from the different stages between the two groups was corrected statistically, no statistically significant difference was found. There was also no significant difference between open and laparoscopic gastrectomy in the occurrence rate of other postoperative complications such as ascites, wound infection, and intra-abdominal abscess. No postoperative mortality occurred.
Conclusions
Laparoscopic gastrectomy is a feasible surgical procedure for patients with moderate hepatic dysfunction.

2.  Preoperative predictors of malignant gastric submucosal tumor 
Purpose
The preoperative prediction of malignant potential in patients with gastric submucosal tumors (SMTs) plays an important role in decisions regarding their surgical management.
Methods
We evaluated the predictors of malignant gastric SMTs in 314 patients with gastric SMTs who underwent surgery in Chonnam National University Hospital.
Results
The malignant SMTs were significantly associated with age (odds ratio [OR], 1.067; 95% confidence interval [CI], 1.042 to 1.091; P < 0.0001), presence of central ulceration (OR, 2.690; 95% CI, 1.224 to 5.909; P = 0.014), and tumor size (OR, 1.791; 95% CI, 1.483 to 2.164; P < 0.0001). Receiver operating characteristic curve analysis showed that tumor size was a good predictor of malignant potential. The most relevant predictor of malignant gastric SMT was tumor size with cut-offs of 4.05 and 6.40 cm.
Conclusion
Our findings indicated that age, central ulceration, and tumor size were significant preoperative predictors of malignant SMTs. We suggest that 4 cm be selected as a threshold value for malignant gastric SMTs. In patients with a gastric SMT larger than 4 cm with ulceration, wide resection of the full thickness of the gastric wall or gastrectomy with adequate margins should be performed because of its malignant potential.

3.  Clinicopathological Features of Female Gastric Carcinoma Patients with Curative Resection: Comparison with Male Patients 
Chonnam Medical Journal  2012;48(2):86-90.
Little is known about the clinicopathological features of female gastric carcinoma (FGC) patients. We compared the clinicopathologic features and outcomes of FGC patients with curative resection with those of male gastric carcinoma (MGC) patients. We reviewed the hospital records of 940 FGC patients between 1986 and 2005 at Chonnam National University Hospital. Multivariate analysis showed that presence of serosal invasion, lymph node metastasis, and operative type were significant prognostic factors for survival of FGC patients with curative resection. Furthermore, the overall 5-year survival rate of FGC patients with curative resection (53.4%) was higher than that of MGC patients (47.6%, p<0.05). In advanced cases, no significant difference was observed in the overall 5-year survival rate between the FGC and MGC patients (41.6% vs 37.4%, p>0.05). Therefore, serosal invasion, lymph node metastasis, and type of operation were statistically significant parameters associated with survival. Early detection is more important for improving the prognosis of female patients with gastric cancer than for male patients.

4.  Multivisceral resection for locally advanced rectal cancer: adequate length of distal resection margin 
Purpose
Locally advanced rectal cancer may require an intraoperative decision regarding curative multivisceral resection (MVR) of adjacent organs. In bulky tumor cases, ensuring sufficient distal resection margin (DRM) for achievement of oncologic safety is very difficult. This study is designed to evaluate the adequate length of DRM in multiviscerally resected rectal cancer.
Methods
A total of 324 patients who underwent curative low anterior resection for primary pT3-4 rectal cancer between 1995 and 2004 were identified from a prospectively collected colorectal database.
Results
Short lengths of DRM (≤1 cm) did not compromise essentially poor oncologic outcomes in locally advanced rectal cancer (P = 0.736). However, especially in rectal cancers invading adjacent organs, DRM of less than 2 cm showed poor survival outcome. In 5-year and 10-year survival analysis of MVR, a shorter DRM (<2 cm) showed 41.9% and 30.5%, although a longer DRM (≥2 cm) showed 72.4% and 60.2% (P = 0.03, 0.044). In multivariate analysis of MVR, poorly differentiated histology, ulceroinfiltrative growth of tumor, and short DRM (<2 cm) were significant factors for prediction of poor survival outcome, although short DRM was not significantly related to local and systemic recurrence.
Conclusion
In locally advanced rectal cancer of pT3-4, a short length of DRM (≤1 cm) did not compromise essentially poor oncologic outcome. In rectal cancers invading adjacent organs and requiring MVR, a shorter DRM (<2 cm) was found to be related to poor survival outcome.
