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.

In April 2014, a Letter of Rapid Safety Communication was issued, because 21 fatalities following administration of paliperidone palmitate (PP) were reported over a 5-month period since its launch in November, 2013. At the Department of Pharmacy of Hakodate Watanabe Hospital (our hospital), we established criteria for the use of long-acting antipsychotic injections (LAIs) when we began to prescribe LAIs at our hospital and shared information on the use of LAIs with pharmacists at community pharmacies by placing seals in medication notebooks. In March 2014, we conducted a questionnaire survey of pharmacists at 223 community pharmacies in Southern Hokkaido to compared the investigation items by the percentage of prescriptions filled in by the department of psychiatry among all the prescriptions dispensed by the pharmacies. The pharmacists who answered that injectable drug use information and seals for medication notebooks were necessary accounted for 75.8% and 74.2% of the responders, respectively. On the other hand, the percentages comprising the acquisition rates of information on injectable drug use and information on the injectable drugs used were low with 12.1% and 7.6% respectively. Also, a significant difference was seen in the recognition of LAI use in the comparison by the percentage of prescriptions filled in by the department of psychiatry among all of the prescriptions dispensed by the pharmacies (p＝0.001). Our results show that collaboration between hospital pharmacists and community pharmacists is necessary to ensure the safe use of LAI.

The patient was a 70-year-old man. He was injured in a motorcycle accident and was brought to the hospital suffering from pulmonary contusions, multiple rib fractures, and a dislocation fracture of the left hip joint. Mechanical ventilation and tracheostomy were performed because of decreased oxygenation. As dysphagia and gait disturbance persisted even after his respiratory condition improved, the patient was transferred to our institution for rehabilitation 63 days after the injury. Rehabilitative intervention for the patient's physical impairments progressed smoothly, and the patient regained independence in activities of daily living. However, 1 week before his scheduled date of discharge, the patient suffered from sudden heart failure at 168 days after the initial injury. Traumatic aortic regurgitation was diagnosed based on the following findings : aortic regurgitation rapidly exacerbated after heart failure, no medical history of heart disease, and no other cause for aortic regurgitation. Surgical treatment with aortic valve replacement was performed. Postoperative recovery was favorable, and the patient was discharged to his home after regaining independence in activities of daily living. Traumatic aortic regurgitation is rare, and patients with this disease often suffer heart failure from a few days to several years after injury. This condition needs to be kept in mind during the rehabilitation process following chest trauma.

We report a 65-year-old man with a mobile thrombus in the distal aortic arch with no previous history of thromboembolic events. There was no evidence of either aneurysmal changes or aortic dissection. Transesophageal echocardiography revealed the presence of a mobile tumor in the distal arch. The patient underwent elective resection. The mobile tumor was attached to the aortic wall, approximately 3cm distal to the left subclavian artery. Histological examination revealed an old thrombus containing calcification. He was discharged on the 22nd postoperative day with no thromboembolic complications. This is the first report of a case of mobile thrombus in the distal aortic arch in Japan.

We reviewed 24 cases of patchplasty for true thoracic aortic aneurysm performed in our hospital up to July 2001. The size of the aneurysm in the ascending aorta was 6.0cm (1 case), and the mean size in the aortic arch was 2.5±0.5cm (4 cases), that in the distal arch was 4.7±1.7cm (11 cases), and that in the descending aorta was 3.7±0.5cm (8 cases). The hospital mortality rate was 12.5% (3 patients out of 24). The causes of death were multiple organ failure, cerebral bleeding and sepsis. In the long-term results, 2 patients had recurrence, but there were no late deaths in relation to the aneurysmal recurrence. We performed open stent operations for severe adhesion and pulmonary dysfunction in the aneurysmal recurrence cases. The postoperative course of these cases was uneventful. The open stent was useful for the treatment of the aneurysmal recurrence in the distal arch.

A 62-year-old man was admitted to our hospital because of acute aortic dissection (DeBakey type III b). Inflammatory findings were detected and methicillin-resistant staphylococcus aureus (MRSA) was detected by blood culture. Appropriate antibiotic therapy was begun but was ineffective. Repeated CT scans revealed dilation of the false lumen with thrombus and perianeurysmal inflammatory change in the lung. A diagnosis of infected aortic dissection was made. The patient was treated by resection of the descending aorta and placement of an in situ Dacron graft covered with a pedicled omental flap. An infected thrombus in the false lumen was confirmed by a positive MRSA culture. Computed tomography was found to be more sensitive in the diagnosis of infected aortic dissection. When the infection is not controlled with antibiotics, prompt surgical treatment should be performed.

During 23 years, 224 cases underwent graft replacement of thoracic aortic aneurysms at our institution. Of these, 14 cases suffered postoperative vascular graft infection. Out of the 14 cases, 13 cases had sternal or mediastinal infections, and one case showed sepsis without these deep wound infections. Six cases were positive by blood culture. We thought that sternal or mediastinal infections had a high possibility of contamination of vascular grafts and that cases with these deep wound infections should be treated as cases of graft infection. Reoperation was done urgently soon after the diagnosis of infection was made. When the wound was not so deep, only debridement was performed. In addition to debridement, continuous irrigation through a chest tube and, recently, pedicled omental flap placement were done, when the wound was deep. Except for the one case without deep wound infection, 13 cases were reoperated. There were 4 hospital deaths; 3 operated cases and the nonoperated case, due to lack of control of their infection. Blood culture were positive in all these four cases. The other 10 cases were discharged from hospital without infection. Infection of vascular grafts after operation for thoracic aortic aneurysms is a serious complication and urgent reoperation should be done. However it should be noted that the mortality rate of cases with positive blood culture is high.

Twenty-two patients who underwent vascular reconstruction for carotid occlusive disease by April 1998 were examined in terms of long-term results. The cause of disease was atherosclerosis in 16, and aortitis in 6. The operation method included CEA in 11 and bypass in 5 cases in the atherosclerosis cases, and CEA in 2 and bypass in 6 cases in aortitis. Cases of occlusive disease included 1 early occlusion (atherosclerosis) and 4 late occlusion (atherosclerosis 2, aortitis 2). The cause of early occlusion was considered to be due to technical factors, but late occlusion was thought to be related to progression of disease, anastomotic intimal thickening, and recurrence of inflammation. It is important to enforce strict operative indications, accurate intraoperative monitoring, and perioperative drug control.

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.
