Purpose: Preoperative sarcopenia worsens postoperative outcomes in various cancer types including colorectal cancer. However, we often experienced postoperative anastomotic leakage in muscular male patients such as Judo players, especially in rectal cancer surgery with lower anastomosis. It is controversial whether the whole skeletal muscle mass impacts the potential for anastomotic failure in male rectal cancer patients. Thus, the purpose of this study was to clarify whether skeletal muscle mass impacts anastomotic leakage in rectal cancer in men. Methods: We reviewed the medical charts of male patients suffering from rectal cancer who underwent colo-procto anastomosis below the peritoneal reflection without a protective diverting stoma. We measured the psoas muscle area and calculated the psoas muscle index. Results: One hundred ninety-seven male rectal cancer patients were enrolled in this study. The psoas muscle index was significantly higher in patients with anastomotic leakage (P<0.001). Receiver operating characteristic curve determined the optimal cut-off value of the psoas muscle index for predicting anastomotic leakage as 812.67 cm2/m2 (sensitivity of 60% and specificity of 74.3%). Multivariate analysis revealed that high psoas muscle index (risk ratio [RR], 3.933; P<0.001; 95% confidence interval [CI], 1.917–8.070) and super low anastomosis (RR, 2.792; P=0.015; 95% CI, 1.221–6.384) were independent predictive factors of anastomotic leakage. Conclusion: This study showed that male rectal cancer patients with a large psoas muscle mass who underwent lower anastomosis had a higher rate of postoperative anastomotic leakage.

We have developed a three-dimensional force display robot (3D robot) to discover and embody needs in rehabilitation site. Then we have exchanged opinions with therapists by using the 3D robot together in rehabilitation site. From a therapist" needs we have developed repeated resistance training system by using the 3D robot as one of the application of the 3D robot. On the basis of the results we have developed a simplified repeated resistance training system equipped with a user interface for easy operation for therapists. Moreover, we have developed a brace for fixation as the attachment between the training system and the patient’s arm. In this paper, we perform the functional evaluation of the simplified repeated resistance training system and the brace in the clinical site. These results are based on the opinions from the therapist and the patient. Moreover, we verify the therapeutic effects of the repeated resistance training using the simplified system for a hemiplegic stroke patient. The AROMs of pronation and supination of the patient were improved after repeated resistance training using the simplified system.
