BACKGROUND: In low rectal cancer, creating a permanent stoma can be avoided by applying a low anterior resection using the double stapling technique. However, the problem of local recurrence is still a major pattern of tumor recurrence in rectal cancer. We aimed to verify the clinicopathologic variables related to exfoliation of tumor cells and searched for an efficient method to remove the tumor cells from the rectal stump during a low anterior resection. METHODS: Forty-four patients who underwent a low anterior resection using the double stapling technique were enrolled prospectively. For patient, we irrigated each rectal stump twice with 500 cc of normal saline through the anus. Two specimens from each irrigation were obtained and examined for any malignant tumor cells. Cases in which no tumor cells were found from the two specimens were defined as Group I, cases in which tumor cells were found in only the first specimen were defined as Group II, and cases in which tumor cells were found in both the first and the second specimens were defined as Group III. Clinicopathologic variables were analyzed with regard to the presence of exfoliated tumor cells in irrigated saline. RESULTS: There were sixteen (36%), fourteen (32%), and fourteen cases (32%) in Groups I, II, and III, respectively, according to the examination results. Age classification (P=0.05) and metastatic lymph nodes (P=0.013) were associated with the presence of tumor cells in irrigated saline (I vs. II, II). CONCLUSIONS: Stump irrigation during a low anterior resection using the double stapling technique is recommended as an easy and simple method to remove exfoliated tumor cells from anastomosis sites, although further study is necessary to elucidate the association between exfoliated tumor cells and local recurrence.

Introduction: The ability to self-regulate eating can improve health. This study aimed to determine the relationship between eating self-regulatory skills, diet quantity, and diet quality among Malaysian university students. Methods: This cross-sectional study involved 132 university students. Eating self-regulatory skill was assessed using the Self-Regulation of Eating Behaviour Questionnaire (SREBQ). Dietary intakes from two 24-hour dietary recalls were used to assess diet quantity and quality. Diet quantity was measured as energy and macronutrient intakes, analysed using NutritionistPro. Diet quality was measured using the Malaysian Healthy Eating Index (M-HEI). The relationship between eating self-regulatory skills, diet quantity, and diet quality were evaluated using tests for differences between means and multiple linear regression. Results: Male participants (n=47) consumed more energy than female participants (n=85) (Male: 1850±570 kcal/day, Female: 1596±567 kcal/day, p=0.015). Participants from the Nutrition and Dietetics (N&D) course (n=49) had better M-HEI scores than participants from other health courses (n=83) (N&D course: 52.7±10.5, non-N&D course: 47.2±10.7, p=0.005). The predictors of energy intake were gender (β=-0.193, p=0.023) and SREBQ score (β=- 0.223, p=0.009). Being female and having higher eating self-regulatory skills were associated with lower energy intake. The predictors of diet quality were university course (β=0.240, p=0.005) and SREBQ score (β=0.181, p=0.033). Studying N&D and having higher eating self-regulatory skills were associated with higher M-HEI scores. Conclusion: Higher self-regulation of eating behaviour score is a factor that contributes to lower daily energy intake and higher diet quality score.
