Purpose: A consensus has been reached regarding diverting stoma (DS) construction in rectal cancer surgery to avoid reoperation related to anastomotic leakage. However, the incidence of stoma-related complications (SRCs) remains high. In this study, we examined the perioperative outcomes of DS construction in patients who underwent sphincter-preserving surgery for rectal cancer. Methods: We included 400 participants who underwent radical sphincter-preserving surgery for rectal cancer between 2005 and 2017. These participants were divided into the DS (+) and DS (–) groups, and the outcomes, including postoperative complications, were compared. Results: The incidence of ileus was higher in the DS (+) group than in the DS (–) group (P<0.01); however, no patients in the DS (+) group showed grade 3 anastomotic leakage. Furthermore, early SRCs were observed in 33 patients (21.6%) and bowel obstruction-related stoma outlet syndrome occurred in 19 patients (12.4%). There was no significant intergroup difference in the incidence of grade 3b postoperative complications. However, the most common reason for reoperation was different in the 2 groups: anastomotic leakage in 91.7% of patients with grade 3b postoperative complications in the DS (–) group, and SRCs in 85.7% of patients with grade 3b postoperative complications in the DS (+) group. Conclusion Patients with DS showed higher incidence rates of overall postoperative complications, severe postoperative complications (grade 3), and bowel obstruction, including stoma outlet syndrome, than patients without DS. Therefore, it is important to construct an appropriate DS to avoid SRCs and to be more selective in assigning patients for DS construction.

A 52-year old woman was referred to our hospital because of abdominal pain and restlessness. A chest contrast-enhanced CT showed huge pericardial effusion and intraluminal defects in the main pulmonary artery. We could not make a diagnosis based on the cytology of the pericardial effusion and histopathology of the mass with a sample taken by a catheter. Therefore, we undertook biopsies of the mass by median sternotomy, which led to the diagnosis of pulmonary intimal sarcoma. The tumor resection was performed to release the right ventricular outflow stenosis. We tried to resect the tumor as much as possible, and reconstructed the pulmonary artery and aortic root. She was discharged to home and survived 5 months after surgery.

BACKGROUND/AIMS: Sclerotherapy with aluminum potassium sulfate and tannic acid (ALTA) has a potent effect on internal hemorrhoids. In this retrospective study, we compared the effects of endoscopic ALTA therapy and standard ALTA therapy.METHODS: We investigated patients who underwent treatment for internal hemorrhoids at our institution between 2014 and 2016. They were divided into a standard ALTA group (n=33, treated using proctoscopy) and an endoscopic ALTA group (n=48). We compared the clinical findings between the 2 groups.RESULTS: There were no intergroup differences in background factors. The mean ALTA dose was 21.9±7.2 mL and 17.8±3.4 mL in the standard and endoscopic ALTA groups, respectively (p<0.01). Adverse events occurred in 4 patients (12.1%) from the standard ALTA group and 6 patients (12.5%) from the endoscopic ALTA group. In both groups, the patients reported good satisfaction with the therapeutic effect at 1 month after the procedure. Hemorrhoids recurred in 2 patients (6.3%) from the standard ALTA group and 4 patients (8.3%) from the endoscopic ALTA group.CONCLUSIONS: Endoscopic ALTA sclerotherapy is equivalent to standard ALTA therapy in terms of efficacy, adverse events, and recurrence. Therefore, it is a useful non-surgical option for patients with internal hemorrhoids who prefer a less invasive treatment.

Background : Connective tissue disease (CTD) is an idiopathic autoimmune disorder which causes systemic chronic inflammation. Inflammation causes various cardiovascular diseases. Systemic steroid use, which is usually the sole treatment for CTD, also causes arteriosclerosis. Although cardiovascular surgery is often necessary in patients with CTD, preexisting multiple organ dysfunction related to CTD, in addition to systemic administration of steroids or other immunosuppressants, is thought to increase the risk of surgery. However, little is known about how the disease process of CTD influences early and late cardiovascular surgery outcomes. Methods : To better understand these issues, we reviewed 31 patients with CTD (study group) and compared their outcomes to those of other patients (control group) who underwent cardiovascular surgery at our institution between April 2008 and November 2013. Results : There were 26 women and 5 men, and the average age was 64.4±16.7 years. CTD types included rheumatoid arthritis in 7 patients, systemic lupus erhythematosus in 6, aortitis syndrome in 6, polymyalgia rheumatica in 3, scleroderma in 3, polymyositis in 3, and others. The procedures included 10 valve cases, 10 coronary artery bypass grafting (CABG) or CABG-valve combination cases, and 11 isolated or complicated thoracic aortic surgery cases. Prior to undergoing these procedures, 24 patients (77.4%) were treated with steroids and/or immunosuppressant, and 6 patients had been diagnosed with interstitial pneumonia in the study group. Moreover, the rate of peripheral artery disease and carotid artery stenosis in the study group was significantly higher than that in the control group. There were no perioperative deaths in the study group. There were no significant differences in terms of major complications such as ischemic events, infection, acute kidney injury, lung injury, and others between the groups. We conducted a follow-up survey for the study group with an average period of 27.8±16.0 months. During the follow-up period, there were 4 late deaths. In addition, 8 patients required readmission, 6 for cardiovascular events and 2 for poor wound healing. All the survivors in the study group showed improved cardiac function and were in the NYHA functional class I and II. Conclusion : Cardiovascular surgery for patients with CTD can provide acceptable early and mid-term results.

Total anomalous pulmonary venous connection (TAPVC) is rarely associated with remarkably small left heart structures. In these types of cases, the hemodynamics resembles that of hypoplastic left heart syndrome, and the treatment strategy is controversial. We present the case of a 1-day-old girl with infracardiac TAPVC, small left heart structures (hypoplastic left heart complex), bilateral superior vena cava, and aberrant origin of the right subclavian artery. We performed a semi-emergent first-stage open palliation for repair of TAPVC, because of pulmonary venous obstruction. We concomitantly performed atrial septal defect (ASD) enlargement and bilateral pulmonary artery banding (BPAB). The postoperative course was uneventful and the left heart structures did not grow, so we performed the Norwood procedure and placed a right ventricle-pulmonary artery shunt with a 5.0 mm artificial graft. Subsequently, the left heart structures were not suitable for biventricular repair, so we chose univentricular repair. The patient underwent a bilateral bidirectional Glenn operation and Fontan completion at 6 and 23 months of age, respectively. TAPVC repair, BPAB, and ASD enlargement are reasonable surgical options for a patient with borderline small left heart structures and TAPVC, as they enable us to wait for growth in the left heart structures and to determine whether univentricular or biventricular repair is suitable.

Objective : The aim of this study is to describe a series of patients undergoing reoperation due to hemolytic anemia after mitral valve surgery and assess the mechanisms and surgical outcomes. Methods : Between 2009 and 2014, we performed redo mitral valve surgery in 11 patients who had refractory hemolytic anemia after mitral valve surgery at Kyoto University Hospital. The mean age of the patients was 72.2±6.8 years old, and there were 5 men. Results : Preoperative echocardiography demonstrated that only 3 patients had ≥ grade 3 mitral regurgitation (MR), the rest of the patients had only mild to moderate MR. The mechanisms of severe hemolysis included paravalvular leakage (PVL) after mitral valve replacement (MVR) in 8 patients, structural valve deterioration (SVD) after MVR using a bioprosthesis in one, and residual/recurrent mitral regurgitation after mitral valve plasty (MVP) in two. All the patients except one (re-MVP) underwent MVR. The mean interval between previous operation and current operation was 14.1±9.4 years in post-MVR cases, and 2.0±1.9 years in post-MVP cases. There were three late deaths, one of which was due to cardiac death (exacerbation of heart failure due to pneumonia). There was one patient who required re-MVR for recurrent hemolysis due to PVL after MVR. Conclusion : Although hemolytic anemia after mitral valve surgery is rare, it often requires reoperation regardless of the degree of MR at late follow-up period. Thus, patients after mitral valve surgery should be carefully followed-up.

BACKGROUND/AIMS: The aim of this study was to examine the convenience of the quality of life and utility evaluation survey technology (QUEST) questionnaire and the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire as self-assessment diagnostic instrument. METHODS: This was a two-way crossover study conducted over 6 weeks from September 2010 to November 2010. The subjects were 60 consecutive patients admitted to the Hiratsuka city hospital with a gastrointestinal condition, regardless of the coexistence of heartburn. They were assigned to fill in both the QUEST and FSSG questionnaires in random order. We analyzed the time taken to complete the questionnaires, whether subjects asked any questions as they filled in the questionnaire, and the questionnaire scores. RESULTS: Comparison of the QUEST and the FSSG revealed significant differences in the completion time (196.5 vs. 97.5 seconds, respectively; P < 0.0001) and in whether subjects asked any questions (37 vs. 15 subjects, respectively; P < 0.0001). Completion time in QUEST scores of > or = 4 was lower than < 4 (170.5 vs. 214.0 seconds, respectively; P = 0.022), and the QUEST score was significantly higher without questions than with question (3 vs. 1 points, respectively; P = 0.025). CONCLUSIONS: This study revealed that the FSSG questionnaire may be easier for Japanese subjects to complete than the QUEST questionnaire.

BACKGROUND/AIMS: The effects of Histamine-2 receptor antagonists and proton pump inhibitors on the gastrointestinal motility have not yet been sufficiently investigated. The aim of this study was to determine the effects of intravenous bolus administration of famotidine and omeprazole on the rate of gastric emptying using the continuous 13C breath test (BreathID system, Exalenz Bioscience Ltd, Israel). METHODS: Twelve healthy male volunteers participated in this randomized, 3-way crossover study. After fasting overnight, the subjects were randomly assigned to receive 20 mg of famotidine, 20 mg of omeprazole or 20 mL of saline alone by intravenous bolus injection before a test meal (200 kcal per 200 mL, containing 100 mg of 13C-acetate). Gastric emptying was monitored for 4 hours after the ingestion of test meal by the 13C-acetic acid breath test performed using the BreathID system. RESULTS: No significant differences in the calculated parameters, namely, the T1/2, Tlag, GEC, beta and kappa, were observed among the 3 test conditions. CONCLUSIONS: The study revealed that intravenous administration of gastric acid suppressant drugs had no significant influence on the rate of gastric emptying in comparison with that of saline alone as a placebo. Our results indicating the absence of any effect of either famotidine or omeprazole on accelerating the rate of gastric emptying suggest that both medications can be administered safely to patients suffering from hemorrhagic peptic ulcers who need to be kept nil by mouth from the viewpoint of possible acceleration of gastrointestinal motility in the clinical setting.

Infected aortic aneurysm is very difficult to treat and is associated with a high mortality rate. A 78-year-old man had been scheduled to undergo selective endovascular repair for distal aortic arch aneurysm. While standby, however, he was admitted to our emergency room because of hemoptysis. Rapid dilatation of the aneurysm shown on serial CT and elevated of inflammatory reactions yielded a diagnosis of infected aortic aneurysm. Because the aneurysm had ruptured into the left lung, emergency surgery was performed. Six days after the first operation, critical bleeding due to anastomotic disruption of the distal aorta caused by infection and subsequent cardiac arrest occurred. We immediately started open chest massage and controlled the bleeding manually in the ICU, while an operating room was prepared. In the redo operation, anastomotic disruption was repaired using the visceral pleura under deep hypothermic circulatory arrest. Anastomotic bleeding is a potentially life-threatening condition, therefore extremely prompt measures are vital. Appropriate management based on the assumption of anastomotic bleeding was very important in the postoperative course of this case of infectious aortic aneurysm.

A study was conducted to evaluate the clinical and hemodynamic performance of the 19-mm Medtronic Mosaic Valve (MMV) in the aortic position, which is a third-generation stented porcine bioprosthesis. Between 2003 and 2006, 9 patients underwent AVR using the 19-mm MMV. None of the patients were suitable for a 19-mm Perimount bioprosthetic valve due to having a small annulus and sinotubular junction. The patients included 3 men and 6 women with a mean age of 73.2±4.97 years and mean body surface area of 1.35±0.11m². Preoperatively, 8 patients were in New York Heart Association class II and 1 was in class III. The reason for surgery was aortic stenosis in 8 patients and aortic regurgitation due to infective endocarditis in 1 patient. Four patients had chronic renal failure and were on hemodialysis, while 1 patient had Crohn's disease. Concomitant coronary artery bypass grafting was performed in 3 patients, and tricuspid valve annuloplasty was done in 1 patient. The follow-up period was 12.0±7.71 months. No deaths occurred, but there was 1 cerebral infarction. Postoperatively, the peak pressure gradient decreased from 81.3±32.7 to 40.3±16.3mmHg (p<0.01). The mean pressure gradient also decreased significantly from 48.8±11.6mmHg to 23.9±9.32mmHg (p<0.01). Left ventricular end-diastolic diameter was 47.9±3.82mm preoperatively and 45.1±7.53mm postoperatively, showing no significant change. The left ventricular mass index also improved from 217.3±46.9 to 160±54.9g/m² (p<0.05). The ejection fraction was 72.0±8.93% preoperatively and 67.6±6.37% postoperatively, showing no difference. Although the postoperative indexed effective orifice area (EOAI) was 0.90±0.11cm²/m², mild patient-prosthesis mismatch (EOAI 0.77cm²/m²) was noted in 1 patient. In conclusion, the early clinical and hemodynamic performance of the 19-mm MMV in small elderly patients was acceptable.
