Objective: To evaluate outcomes of palliative surgery for malignant bowel obstruction (MBO) and identify factors associated with postoperative survival. Methods: We retrospectively reviewed 27 patients who underwent palliative surgery for MBO between April 2014 and March 2023. Clinical data including symptom relief, oral intake, discharge status, and overall survival (OS) were analyzed. Results: Median age was 70 years; 23 patients were Stage IV. Primary tumors included colon-rectum (15), stomach (6), pancreas (2), and others (4). Peritoneal dissemination was present in 18 cases. Median preoperative Palliative Prognostic Index (PPI) was 3.0. Postoperative symptom relief was achieved in 96.3%, oral intake in 81.5%, and discharge in 51.9%. Median OS was 118 days. Peritoneal dissemination and oral intake status were significantly associated with OS; sex, age, and PPI were not. Conclusion: Palliative surgery may improve outcomes such as symptom relief, oral intake, discharge to preferred care settings, and survival. These findings support its role in advance care planning and enhancing quality of life in patients with terminal cancer.

BACKGROUND: Predictive factors for the efficacy of dipeptidyl peptidase-4 (DPP-4) inhibitors for lowering glycosylated hemoglobin (HbA1c) remain unclear in patients with type 2 diabetes mellitus. The aim of this study is therefore to clarify predictive factors of the efficacy of DPP-4 inhibitors for lowering HbA1c after 12 months of treatment. METHODS: A total of 191 consecutive type 2 diabetic patients (male sex 55%, mean age, 68.3+/-35.8 years), who had been treated with DPP-4 inhibitors for 12 months, were enrolled in this study and evaluated retrospectively. RESULTS: After 12 months of DPP-4 inhibitor treatment, random blood glucose level, and HbA1c level, decreased from 167+/-63 to 151+/-49 mg/dL (P<0.01), and from 7.5%+/-1.3% to 6.9%+/-0.9% (P<0.01) respectively, without severe side effects. Multiple regression analysis showed that predictors of DPP-4 inhibitor treatment efficacy in lowering HbA1c level after 12 months were a decrease in HbA1c level after 3 months of treatment, a high baseline HbA1c level, a low baseline body mass index, and the absence of coronary artery disease. CONCLUSION: Most suitable candidates for treatment with DPP-4 inhibitors are diabetics who are not obese and do not have coronary artery disease. In addition, long-term efficacy of DPP-4 inhibitors can be predicted by decrement of HbA1c after 3 months of treatment.

Objectives: Bony impingement of the proximal femur on the pelvis is an important factor for dislocation after total hip arthroplasty (THA). We evaluated bony impingement after THA using the rotation matrix derived from postoperative computed tomography (CT) images.
Patients and Methods: One hundred and seven hip joints were subjected to primary THA via a posterolateral approach. We used the rotation matrix derived from CT images to calculate internal rotation (IR) limit prior to bony impingement, and compared this limit with the intraoperative limit.
Results: The average calculated IR limit was 63 degrees (range: 30 to 85 degrees). The average intraoperative IR limit was 49 degrees (range: 20 to 70 degrees). The correlation between the intraoperative IR limit (Y) and the calculated IR limit (X) was expressed as Y=8.9+0.66X (R=0.73; p < 0.0001).
Conclusions: We could show a patient´s safe range of motion prior to bony impingement, and this will be a good indicator for dislocation not occurring during postoperative rehabilitation.

We report two cases the first was a 74-year-old woman who had received coronary artery bypass grafting [SVG-to-LAD, SVG-to-Cx, SVG-to-RCA, the left internal thoracic artery (LITA) was mobilized but was unsuitable for the graft] two years previously. Postoperative angiography revealed graft occlusion. Since repeated catheter intervention was not successful, reoperation was performed. A MIDCAB procedure with radial artery graft and proximal anastomosis was performed on the left axillary artery. The operation was successful and there were no complications. Two weeks after the operation, the graft patency was confirmed and she was discharged. The second case was a 64-year-old man who received coronary artery grafting (LITA-to-LAD, SVG-to-Cx and SVG-to-RCA). Two months after the operation, recurrent chest pain was caused by severe stenosis of the LITA anastomotic site. Percutaneous transluminal coronary angioplasty was performed but was unsuccessful. He received redo CABG in the same manner using the saphenous vein. The postoperative course was uneventful and he was discharged 6 days after the operation. This procedure is useful for the patients whose left internal thoracic artery has been used on a previous operation. Good early results were obtained in both patients.

A 62-year-old man was transferred to our institution with ventricular fibrillation. Percutaneous cardiopulmonary support (PCPS) was established and he underwent successful percutaneous transluminal coronary angioplasty. Since his left ventricular function did not recover, he was placed on a left ventricular assist system (LVAS). Under general anesthesia, a 10-cm longitudinal incision was made on the right parasternum. The third and fourth cartilages were completely resected. The pericardium was incised longitudinally. At first, an inflow cannula was insected to the right side of the left atrium. The ascending aorta was then partially excluded and an outflow cannula with a 10mm Gore-Tex prosthesis was anastomosed end-to-side to the aorta with a continuous Gore-Tex suture. After the pump was established, PCPS was gradually discontinued. During 9 days of support, his left ventricular function recovered and subsequently he was weaned from LVAS. Unfortunately, he died two days after LVAS removal. We think this procedure is useful because it is easy to perform, reduces the bleeding, shortens the operating time.

We began gastric mass survey at our hospital in May, 1980. During 3 years and 8 months since then, (May, 1980-December, 1983) we performed screening examinations to 16, 341 people by indirect radiography, and checked 2, 824 cases (17.3%) for thorough examination. Among these cases, 2, 083 (73.8%) received endoscopic examination actually, and 55 cases of gastric cancer were discovered. The discovery rate of gastric cancer was 0.336 per cent.
35 cases of these 55 gastric cancer were operated in the surgical department of our hospital. 34 cases were resected (rate of resection was 97.1%) and 33 cases were resected curatively (rate of curative resection was 94.3%). These results were better than that of gastric cancer cases from out-patient clinic of the same period. The results of cases from out-patient clinic of our hospital were: total number of cases 321, resected cases 254 (79.1%), curative resection 189 cases (58.9%), respectively.
