Abstract
Objectives Double incontinence (DI), which is the co-occurrence of fecal incontinence (FI) and urinary incontinence (UI), increases with age and has a greater negative impact on the quality of life (QOL) than either incontinence alone. We aimed to assess lower urinary tract symptoms (LUTS) in patients with FI to elucidate the prevalence and characteristics of DI. Methods This study enrolled consecutive patients who visited our hospital with FI symptoms. FI was evaluated using the Cleveland Clinic Florida Fecal Incontinence Score (CCFIS). LUTS were assessed using the International Prostate Symptom Score (IPSS), QOL score (IPSS-QOL) and Overactive Bladder Symptom Score (OABSS). Results This study evaluated 140 patients (96 women [mean age: 70.7 years] and 44 men [mean age: 74.4 years]). The mean IPSS was significantly higher in men than in women (12.0 vs. 7.5, p = 0.003). A positive correlation was found between IPSS and CCFIS in women (r = 0.256, p = 0.012) but not in men. For both sexes, the older group (aged ≥70 years) had higher OABSS scores and more urge UI instances than the younger group (aged ≤69 years). Of the 140 patients with FI, 78 (55.7%) had DI, and DI was more common in women than in men (63.5% vs. 38.6%, p = 0.006). Conclusions The characteristics of LUTS and UI in patients with FI were comparable to those in the general population for both sexes; however, the prevalence of DI was much higher among patients with FI than that in the general population.

Abstract
Objectives Conventional anal dilatation for anal fissures has long been abandoned because of the high incidence of anal incontinence. However, less invasive and more precise dilation techniques have been developed that have shown high healing and low incontinence rates. This study aimed to evaluate the efficacy and safety of controlled anal dilatation (CAD) using a standardized maximum anal diameter. Methods This study included 523 patients who underwent CAD for chronic anal fissures between January 2010 and December 2014. CAD was performed under sacral epidural anesthesia. The index fingers of both hands were placed in the anus and dilated evenly in various directions. CAD was completed when the anus was dilated to the sixth scale (35 mm in diameter) using a caliber ruler. Results The mean anal scale size expanded from 3.1 to 5.8 (p<0.001). Non-healing was observed in nine patients (1.7%) at 1 month postoperatively, six of whom underwent additional CAD. The mean maximal anal resting pressure (mmHg) decreased from 90.2 to 79.7 at three months postoperatively (p<0.001). Postoperative complications were observed in 11 (2.1%) patients, of whom three patients with thrombosed hemorrhoids underwent resection. None of the patients complained of anal incontinence during the mean follow-up period of 16.6 months. The cumulative recurrence-free rates at three and five years were 87.9% and 69.2%, respectively. Conclusions CAD is technically simple and safe and can achieve reasonable long-term outcomes. Thus, CAD appears to be the preferred procedure for patients with chronic anal fissures who do not respond to conservative treatments.

Abstract
Objectives Defecation disorders (DD) are characterized by impaired rectal evacuation due to inadequate defecatory propulsion and/or dyssynergic defecation. DD are assessed by rectal and anal pressures during attempted defecation using anorectal manometry (ARM). Thus far, at least four types of dyssynergic patterns have been recognized on ARM. This study aimed to compare the manometric parameters and dyssynergic patterns between men and women with DD. Methods This study enrolled consecutive patients undergoing anorectal tests for symptoms of DD. Anorectal pressure was measured using a waveform ARM system. DD were diagnosed based on the results of ARM, balloon expulsion tests, and barium defecography. Dyssynergic patterns were defined as a paradoxical increase in anal pressure with (type I) or without (type II) an adequate increase in rectal pressure and failure of a reduction in anal pressure with (type III) or without (type IV) an adequate increase in rectal pressure. Results This study evaluated 324 women and 234 men. Based on anorectal tests, 73.1% men and 54.6% women were diagnosed with DD. Rectal and anal pressures during attempted defecation in patients with DD were significantly higher in men than in women. Type I patterns were more common in men (64.9%) than in women (28.2%). Conversely, type II (42.9% vs. 24.0%) and IV (20.9% vs. 5.8%) patterns were observed more frequently in women than in men. Conclusions Men were more likely to experience dyssynergic defecation whereas women were more likely to experience inadequate defecatory propulsion. However, future studies are warranted to confirm these results.

Abstract
Objectives Anorectal sensation is an essential component for maintaining normal defecation and continence. This study aimed to investigate changes in anorectal sensation with age and sex using the anorectal sensory threshold to electrical stimulation in a large population with a broad age spectrum. Methods This study enrolled consecutive adult patients (20-89 years old) who underwent anorectal physiology tests to screen for functional or organic anorectal disease. Anorectal sensitivity was measured using an endoanal electrode with a 45-mm long bipolar needle. A constant electrical current was delivered to the lower end of the rectum and the anal canal. The minimum current in milliamperes at which the initial sensation was felt was defined as the sensory threshold. Results Overall, 888 patients were included in this study. The most frequent comorbidities were constipation and hemorrhoids. The median sensory threshold for all patients was 0.5 (interquartile range, 0.2-1.5) mA, and the overall sensory threshold was significantly higher in men than in women. The 95% confidence interval of the sensory threshold for men and women were 0.1-6.8 and 0.1-5.1 mA, respectively. The sensory threshold increased significantly with age in both sexes (men, r = 0.384; women, r = 0.410). There was no sex difference in the sensory threshold between ages 20 and 40 years; however, between ages 50 and 70 years, men had a higher sensory threshold than women. Conclusions The anorectal sensory threshold to electrical stimulation increased with age, and the influence of aging was more significant in men than in women.

Abstract
PURPOSE Perianal injection of bulking agents is an attractive treatment option for patients with mild to moderate fecal incontinence (FI). Various bulking agents have been used for injection therapy, but the optimal injection materials and methods are yet to be standardized. This study aimed to evaluate the effects of injection therapy using aluminum potassium sulfate and tannic acid (ALTA) in the management of FI. METHODS This study included consecutive patients who underwent ALTA injection therapy for FI at our institution. The procedure was performed with the patient in the jackknife position, under caudal epidural anesthesia. The procedure consisted of a 4-step injection to the 3 main cushions and a multipoint injection to the remaining submucosa of the anal canal. RESULTS Seventy-seven patients (mean age, 76 years) were enrolled in the study. The mean Cleveland Clinic incontinence score of 11.9 ± 4.1 at baseline significantly improved to 7.3 ± 5.2 at 3 months following treatment. The mean maximal resting pressure also increased significantly 3 months after the intervention. Postoperative complications were observed in 3 patients (3.9%), and all events were mild. The mean duration of postoperative follow-up was 17.5 months. The cumulative recurrence-free rate at 3 years was 72.4%. CONCLUSION ALTA injection for FI is safe, easy to perform, and provides reasonable mid-term outcomes. Moreover, concomitant anorectal diseases that may be contraindicated by other injectable bulking agents could be treated simultaneously. Therefore, ALTA injection is a promising alternative in the absence of other injectable agents.

Abstract
Objectives: Surgical repair of anal sphincter defects in patients with fecal incontinence (FI) has been associated with excellent or good short-term results; however, its benefits have been shown to deteriorate over long-term follow-up. When sphincteroplasty fails or is not feasible, the subsequent surgical options are limited. This study aimed to evaluate the efficacy of anal encirclement using the Leeds-Keio ligament in patients with FI. Methods: The inclusion criteria for the procedure were failure of or unsuitability for sphincteroplasty and the presence of a patulous anus (diameter, ≥35 mm). The artificial ligament was routed outside the external anal sphincter at the depth of the middle anal canal under caudal epidural anesthesia. Results: Fourteen patients (mean age, 79.4 years; 8 females) with FI were included. Of these, seven (50%) showed a ≥50% reduction in the Cleveland Clinic Florida Fecal Incontinence Score (CCFIS). The mean CCFIS of 13.6 at baseline significantly improved to 7.9 3 months after surgery. The mean maximal anal resting pressure significantly increased from 16.8 mmHg to 22.6 mmHg. Postoperatively, temporary fecal impaction was observed in one patient (7%). None of the cases required removal of the artificial ligament or additional operative interventions for FI during the mean follow-up period of 31.9 months. Conclusions: Anal encirclement using the Leeds-Keio ligament was technically simple and safe and achieved good short-term outcomes. Therefore, this technique appears to be a simple solution for sphincter defects and may become an important surgical option for patients with FI and a patulous anus.

Abstract
Purpose Perineal procedures are an important surgical option for frail and high-risk patients with rectal prolapse. This study aimed to evaluate the efficacy and safety of combined therapy using injection sclerotherapy, with aluminum potassium sulfate and tannic acid (ALTA), and the Thiersch procedure, using the Leeds-Keio ligament (ALTA-Thiersch). Methods This study included 106 consecutive patients (mean age, 81.2 years) who underwent ALTA-Thiersch for rectal prolapse. The procedure was performed under caudal epidural anesthesia. ALTA was injected into the submucosa from the tip of the prolapsed rectum down to the dentate line, circumferentially, at 20 to 40 locations. The ligament tape was placed outside the external sphincter muscle and at an approximate depth of 2 cm into the middle anal canal. Results Of 106 patients, rectal prolapse was cured shortly after surgery in 105 patients. An additional tape was inserted in 1 patient who had persistent prolapse. Postoperative complications were observed in 27 patients (25.5%). Fecal impaction occurred in 12 patients; however, since it was temporary, no tape removal was required. Of the 12 cases in which the tape was infected or exposed, 11 required tape removal. There were 18 cases of recurrence at a mean follow-up of 22.1 months. Cumulative recurrence rates at 3 and 5 years were 21.3% and 38.6%, respectively. Conclusion ALTA-Thiersch is a simple and safe procedure for rectal prolapse, having reasonable outcomes. The use of the Leeds-Keio ligament for anal encircling can help compensate for the disadvantages of the Thiersch operation.

Abstract
BACKGROUND/AIMS Defecation disorders (DD) are part of the spectrum of chronic constipation with outlet obstruction. Although anorectal physiologic tests are required for the diagnosis of DD, these tests are not available in many institutions. This study aims to investigate the predictivity of DD using rectosigmoid localization of radiopaque markers in a colonic transit study. METHODS A total of 169 patients with refractory constipation with a mean age of 67 years were studied. All patients underwent anorectal manometry, a balloon expulsion test, and a colonic transit study. Barium defecography was performed if needed. The relationship between DD diagnosed by these anorectal tests and the rectosigmoid accumulation of markers was examined. RESULTS Seventy-nine (46.7%) patients were identified to have DD based on anorectal test combinations. Rectosigmoid accumulation of markers was observed in 39 (23.1%) patients. The sensitivity and positive predictive value of rectosigmoid accumulation for identifying DD were 31.6% and 64.1%, respectively. Rectosigmoid accumulation provided poor discrimination of DD from normal transit constipation, at a specificity of 82.1% but with a sensitivity of only 10.6%. In discriminating DD from slow transit constipation, rectosigmoid accumulation was found to be useful with a positive likelihood ratio of 5.3. CONCLUSION s Rectosigmoid accumulation of markers can differentiate DD from slow transit constipation. However, non-rectosigmoid accumulation does not exclude the presence of DD.

Abstract
Objectives: This retrospective, observational study aimed to evaluate the tolerance and efficacy of polyethylene glycol 4000 plus electrolytes (PEG 4000) in elderly patients with chronic constipation. Methods: PEG 4000 powder was orally administered once daily at a dose of one or two 6.9 g sachets as the initial dose. The outcome measures were changes in the Cleveland Clinic Constipation Score (CCCS) and the Bristol Stool Form Scale (BSFS) value before and 2 weeks after drug administration. Results: This study included 324 patients aged ≥65 years (mean age: 78.6 ± 7.6 years, range: 65-100 years) with chronic constipation. The total CCCS was noted to significantly improve from 11.5 ± 4.6 at baseline to 7.4 ± 5.2 after drug administration. All CCCS sub-scores also improved significantly. The average BSFS value at baseline (2.5 ± 1.6) significantly improved to 4.3 ± 1.1 after treatment. Side effects (16 events) were observed in 13 patients (4.0%), with the most common being diarrhea (6 patients, 1.9%). All events were mild in severity, with none of the symptoms being serious. The cumulative treatment continuation rate at 1 year was 83.1%. Conclusions: PEG 4000 treatment was safe, effective, and well tolerated in elderly patients with chronic constipation. Thus, it appears to be a promising drug that can be continued for a long time.

Abstract
Objectives: A retrospective, observational study was conducted to examine the efficacy and safety of elobixibat, a novel therapeutic agent for chronic constipation, in Japanese elderly patients aged ≥ 65 years with chronic constipation. Methods: The study was conducted at Kunimoto Hospital. Patients who visited the hospital from April 2018 to March 2019 due to symptoms of chronic constipation and who took elobixibat were enrolled. The outcome measures were changes in the Constipation Scoring System (CSS) score and the Bristol stool form scale (BSFS) before and after elobixibat administration. Results: The study included 150 patients. The total CSS score significantly improved from 11.7±4.5 at baseline to 9.3±5.2 two weeks after drug administration. The improvement was confirmed in six out of eight CSS items. The BSFS at baseline of 2.5±1.8 was improved to 3.4±1.7 two weeks after treatment, nearly close to the normal stool consistency of 4. Adverse reactions were observed in 18 of 150 patients (12.0%) with 21 events, most commonly diarrhea in nine patients (6.0%) and abdominal pain in eight patients (5.3%). Conclusions: Elobixibat improved not only the frequency of bowel movements but also alleviated various symptoms of constipation, such as difficulty with evacuation and sensations of incomplete evacuation in elderly patients with chronic constipation. All adverse drug reactions were mild in severity with no safety concerns.

Abstract
Objectives: The purpose of this study was to investigate whether the symptoms of fecal incontinence (FI) or anal sphincter dysfunction are improved by daikenchuto (DKT). Methods: This is a retrospective observational study that analyzes the effects of DKT. The study was conducted at Kunimoto Hospital. Patients who visited the hospital from January 2012 to December 2016 due to symptoms of FI with a certain degree of chronic constipation and who took DKT were enrolled. The drug to be evaluated was “Tsumura Daikenchuto Extract Granules for Ethical Use (TJ-100)” manufactured by Tsumura & Co., Tokyo, Japan. The primary outcome measures were changes in the scores of the Cleveland Clinic Incontinence Score (CCIS) and Constipation Scoring System (CSS) before and after the administration of DKT. Results: A total of 157 patients were enrolled. On the CCIS, “leakage of solid stool,” “leakage of liquid stool,” “pad use,” and “total score” were significantly improved. On the contrary, on the CSS, the score of “type of assistance” was significantly improved after the administration of DKT, but no significant difference was found in the total score. On the Bristol Stool Form Scale, the administration of DKT showed a tendency to normalize stool consistency. Maximum resting anal pressure and maximum squeeze anal pressure significantly increased after the administration of DKT. No side effects caused by DKT were observed during the study. Conclusions: DKT appears to be a safe and useful agent for the management of FI in patients with defecation disorders and internal anal sphincter dysfunction.

Abstract
A 50-year-old-woman underwent high anterior resection for sigmoid colon adenocarcinoma. Modified oxaliplatin/l / -LV/ 5-FU(mFOLFOX6)was started as adjuvant treatment due to final-stage III b. Granisetron 3 mg and dexamethasone 8 mg for prophylaxis chemotherapy-induced nausea and vomiting (CINV) were administered intravenously 30 min before oxaliplatin administration. Grade 3 delayed CINV was observed at course 4. CINV could not be controlled by any rescue medications. We adopted a neurokinin-1 receptor antagonist (aprepitant) that alleviated the emetic effects of substance P. The oral aprepitant dose was 125 mg on day 1 and 80 mg on days 2 and 3. Afterward, delayed vomiting was completely controlled and chemotherapy could be continued to course 12. Aprepitant is a very active antiemetic drug for the prevention of delayed nausea and vomiting induced by mFOLFOX6 regimen.

Abstract
PURPOSE No surgical method for repair of total rectal prolapse has been established as optimal. We describe a new technique that uses ALTA (aluminum potassium sulfate and tannic acid) injection as a simple perianal procedure for total rectal prolapse. METHODS Fourteen patients with total rectal prolapse were treated with sclerosing therapy by using ALTA injection. Via a perianal approach, 0.5 to 1 ml of ALTA solution was injected along a linear track into the submucosa at 30 to 80 different sites, totaling 20 to 60 ml. RESULTS All 14 patients treated with injection sclerotherapy were cured, with no intraoperative or postoperative complications. One patient required a repeat injection after two months to be cured. No exacerbation of constipation has resulted, and no stenosis has been evident on rectal examination. In seven of ten patients presenting with fecal incontinence, this complaint resolved after therapy. CONCLUSIONS ALTA sclerotherapy yielded satisfactory results in total rectal prolapse, causing no alteration in neurophysiology of bowel function. Injection sclerotherapy should be recommended as the first procedure for treatment of total rectal prolapse.

Abstract
Aortic coarctation in adults is sometimes associated with a fragile aortic wall and may be complicated by coronary artery disease and ascending aortic dilation. Successful management of aortic coarctation in a 45-year-old man with coronary artery disease is described. Tube graft replacement was carried out without cross clamping, under circulatory arrest with axillary artery and graft inflow.

Abstract
Acute distal aortic dissection rarely causes spinal cord ischemia presenting with paraplegia or paraparesis. Spinal cord involvement has poor outcomes, and there is no established effective treatment for this disorder. In this report we describe the acute conservative treatment of two cases of paraplegia/paraparesis due to acute type B aortic dissection. Early reversal of lower-limb dysmobility was achieved.

Abstract
BACKGROUND Although endovascular stent-grafting (SG) has become acceptable for blunt aortic injury (BAI), open surgical repair (OR) does provide reliable, good long-term results. A current surgical strategy for BAI, taking account of associated brain injury, is presented and preferable initial management for BAI is proposed. METHODS AND RESULTS The surgical strategy for BAI was established in 2001: SG is performed for patients with obvious brain injuries, but OR is performed for patients without brain injury, and conservative treatment should be used initially for patients with critical non-aortic injuries. Between 2001 and 2004 20 patients with BAI were admitted to hospital: 16 blunt aortic ruptures and 4 blunt aortic dissections. Of them 15 patients underwent surgery (SG, 9; OR, 6) and 5 patients were treated conservatively. One patient died from associated lung injury after SG, all patients treated conservatively died because of associated brain injuries or another rupture of BAI, and 2 elderly patients treated by OR died within 1 year from postoperative respiratory failure. CONCLUSION This brain-injury conscious surgical strategy for BAI provided acceptable early results. OR should be chosen for young patients without brain injury, but endovascular SG seems to be a better initial treatment for elderly patients or patients with other comorbidities.

Abstract
Two high-risk patients underwent an endovascular stent-grafting for thoracoabdominal aortic aneurysms (TAAA) following bypass-grafting to the visceral arteries. The first patient was a 73-year-old woman with severe ischemic heart disease (IHD) and chronic respiratory failure. The second patient was a 59-year-old woman with myelodysplastic syndromes (MDSs) and hepatic cell carcinoma (HCC). In general, TAAA is not considered to be indicated for endovascular stent-grafting because of the need to revascularize the visceral vessels. However, in some selected cases, such as the two cases presented herein, endovascular stent-grafting combined with bypass-grafting of the visceral arteries can be a feasible and a less-invasive alternative to conventional surgery.

Abstract
Acute distal aortic dissection sometimes causes one or more visceral vessels to be stenosed by the thrombosed false lumen. Although stenosis of the only celiac artery (CA) usually does not cause ischemic symptoms because of the extensive collateral pathways of the mesenteric circulation, we experienced a rare case of CA compression syndrome which was caused by acute type B aortic dissection. The principal symptom was severe epigastric pain that was refractory to medicinal treatment. The angiogram showed absence of the anatomically well-developed collateral pathways between the CA and the superior mesenteric artery. We treated the patient with percutaneous transluminal angioplasty in the CA. This report indicates that attention should be given to the possibility of CA compression syndrome in the case of acute distal aortic dissection and that endovascular management can be successfully applied to control symptoms caused by the syndrome, which is otherwise extremely difficult to repair directly by surgery.

Abstract
There are few published reports on endovascular stent grafting for thoracic aneurysms in Jehovah's Witnesses. Between 2001 and 2003, we performed endovascular stent grafting for a thoracic aneurysm in three patients of the Jehovah's Witness faith. Two patients had a thoracic aortic aneurysm and one had a chronic type-B dissection. The stent graft was constructed from a self-expanding Z-stent and thin-walled woven polyester fabric. None of the patients required perioperative blood transfusion, there was no postoperative endoleak, and all recovered uneventfully and were discharged from hospital. Thus, stent-graft repair of thoracic aneurysms in Jehovah's Witnesses is feasible and can be achieved without the need for blood transfusion.

Abstract
OBJECTIVE The risk of stroke caused by dislodgment of loose atheromatous plaque or mural emboli is increased by cross-clamping of the aorta. Some patients undergo descending thoracic aortic aneurysm repair with proximal aortic cross-clamping between the left common carotid artery and the left subclavian artery. The objective of this study was to determine the influence of proximal aortic cross-clamping in arteriosclerotic aneurysm or dissecting aneurysm repair. METHODS Between May 1984 and May 2003, 81 patients underwent elective surgery for distal arch or descending aortic aneurysm repair with proximal aortic cross-clamping between the left common carotid artery and the left subclavian artery. To evaluate the influence of the proximal aortic cross-clamping, patients were divided into two groups: patients who had undergone arteriosclerotic aneurysm repair (group I, n=25) and patients who had undergone dissecting aneurysm repair (group II, n=56). RESULTS Eight (9.9%) of the 81 patients had a stroke. Six strokes occurred in operations for arteriosclerotic aneurysm repair group I and two strokes occurred in operations for dissecting aneurysm repair group II (24 vs 3.6%; p=0.009). In-hospital mortality rates were 12% in group I and 8.9% in group II (p=0.70). Major postoperative complications included renal failure requiring hemodialysis (in 4.2% of the patients in group I and in 8.3% of the patients in group II, p=0.99) and pulmonary complication (in 20% of the patients in group I and in 16% of the patients in group II, p=0.67). CONCLUSION Cross-clamping between head vessels should be avoided if at all possible when operating on patients who have arteriosclerotic descending thoracic aneurysms.

Abstract
BACKGROUND We have performed descending thoracic aortic aneurysm repairs with partial cardiopulmonary bypass, including heparin-coated circuits. The aim of this study was to evaluate (i) the impact of partial cardiopulmonary bypass on distal organ function and surgical outcomes; and (ii) the effectiveness of using heparin-coated circuits for preventing bleeding complications. METHODS From July 1980 to June 2004, 309 patients underwent descending thoracic aortic aneurysm repairs using partial cardiopulmonary bypass. Their mean age was 61 years (range 19-81 years). One hundred of the 309 patients underwent repair of descending thoracic aortic aneurysm with heparin-coated circuits. Blood data for renal and hepatic function were collected on the day before the operation and postoperative days. RESULTS The in-hospital mortality was 15%. Distal organ dysfunction included spinal cord dysfunction in 2 patients (0.7%) and renal failure necessitating hemodialysis in 15 patients (5%, 15/297: excluded 12 dialysis patients). Multivariate analyses showed that preoperative hemodialysis and emergency operation were risk factors for operative mortality and that emergency operation was a risk factor for requiring hemodialysis. Renal and hepatic function normalized by 2 weeks after surgery. There were no significant differences between the heparin-coated group and nonheparin-coated group in amounts of packed red cells, fresh frozen plasma, and platelets transfused during the procedures. CONCLUSIONS Our data showed that partial cardiopulmonary bypass is a safe and effective method for distal perfusion. Using this technique, descending thoracic aortic aneurysm repair can be performed with acceptable mortality and morbidity. However, the superiority of heparin-coated circuits over nonheparin-coated ones was not proved.

Abstract
BACKGROUND The mortality of patients with descending thoracic aortic rupture who are treated by conventional surgery is high. Our current strategy for the management of descending thoracic aortic rupture is to treat seriously ill patients with endovascular stent-grafting using handmade grafts, and to treat other patients with traditional open repair. The aim of this study was to assess the early results of our strategy. METHODS Twenty-nine consecutive patients with descending thoracic aortic rupture were referred to Sapporo Medical University Hospital from June 2001 to January 2004. Eighteen of these 29 patients were selected for endovascular stent-grafting because of polytrauma (n = 7), comorbidities (n = 6), advanced age (n = 2), past history of left thoracotomy (n = 2), and patient's preference (n = 1). The remaining 11 patients underwent traditional graft replacement of the diseased aorta. Their outcomes and follow-up data were collected and analyzed retrospectively. RESULTS The in-hospital mortality rate was 14% (4/29). The mortality rate for surgical patients and stent-grafting patients was 9% (1/11) and 17% (3/18), respectively. The survival rate of patients at 2 years was 63% +/- 10%. In the follow-up period, 2 of the 18 patients who underwent endovascular stent-grafting required open repair, and 1 patient underwent a redo endovascular stent-grafting procedure because of stent failure. One of these 3 patients died of an intraoperative retrograde type A aortic dissection. CONCLUSIONS The early results of endovascular stent-grafting for the treatment of high-risk patients with descending thoracic aortic rupture are promising. Early results of open repair can also be improved by the selection of stabilized patients. However, the requirement of reintervention indicates that detailed follow-up examinations in patients who have undergone endovascular stent-grafting with handmade stent-grafts should be performed.

Abstract
PURPOSE We evaluated the surgical results of minilaparotomy abdominal aortic aneurysm (AAA) repair in comparison with those of standard open repair and retroperitoneal approach repair. METHODS Between February 2000 and January 2003, 30 patients with AAA underwent minimal incision laparotomy repair (MINI) through an abdominal incision 7-12 cm long. Their clinical characteristics and in-hospital outcome were then compared with those of patients who had undergone repair of AAA by a standard open technique (OPEN) or retroperitoneal approach technique (RETRO). RESULTS There were significant differences between the MINI, OPEN, and RETRO groups in the time until the patient was able to resume eating (2.4 +/- 1.0 vs 4.4 +/- 2.4* vs 2.8 +/- 1.9 postoperative days [PODs], respectively; *P < 0.05), the time until ambulation outside the room (2.1 +/- 0.7 vs 3.5 +/- 1.3* vs 2.5 +/- 1.9 PODs, respectively; *P < 0.05), and the operation times (188 +/- 43* vs 256 +/- 77 vs 238 +/- 59 min, respectively; *P < 0.05). CONCLUSION Minilaparotomy repair is a feasible technique, which combines the benefits of a small incision with those of conventional open repair. With the exception of patients with an iliac artery aneurysm extending to the external or internal iliac artery, MINI repair should be considered for the elective treatment of patients with aortic disease.

Abstract
BACKGROUND The purpose of this study was to determine whether the artery of Adamkiewicz (ARM) can be detected by magnetic resonance angiography and to determine the usefulness of preoperative magnetic resonance angiography evaluation of the ARM. METHODS Between April 2000 and December 2003, 120 patients underwent magnetic resonance angiography for detection of the ARM. The morphology of the anterior spinal artery at the ARM junction, as revealed by magnetic resonance angiography, in 99 patients in whom ARM was preoperatively detected was classified into the following three types: noncontinuation of the anterior spinal artery above the ARM junction (type A), continuation of the anterior spinal artery above and below the ARM junction (type B), and noncontinuation of the anterior spinal artery below the ARM junction (type C). RESULTS The ARMs were detected in 99 (83%) of 120 patients, and from a total of 110 ARMs 105 (95%) originated from intercostal arteries branching from the left side and 94 (86%) originated between Th9 and Th11. Two ARMs were found in 11 (11%) of 99 patients in whom ARMs were detected. In 107 patients, who underwent magnetic resonance angiography to reveal the morphology of the anterior spinal artery at the ARM junction, the patterns of the anterior spinal artery were type A in 59 patients (55%), type B in 21 patients (20%), type C in 3 patients (3%) and not classified in 24 patients (22%). No spinal cord injury occurred in patients in whom the ARM had been preoperatively detected. CONCLUSIONS Preoperative detection of the ARM is possible by magnetic resonance angiography and is very useful for reducing the incidence of ischemic injury of the spinal cord.

A rare case of native valve endocarditis affecting both the normal mitral and tricuspid valves is presented. A 25-year-old woman with an acute ischemic stroke was found to have vegetation secondary to infective endocarditis as the embolic source. One month after the onset of embolic cerebrovascular intervention, a valve repair with the implantation of artificial chordae, sliding commissuroplasty, and ring annuloplasty resulted in a complete recovery.

Abstract
Surgical results were compared between 18 patients (group A) who underwent preoperative anatomic characterization of the Adamkiewicz artery by magnetic resonance angiography (MRA) and 38 patients (group B) without such imaging. In group A, intercostal or lumbar arteries related to the aneurysm were reattached to the graft only when they represented the origin of the Adamkiewicz artery. In group B, reconstruction from the Th 7 intercostal and the L2 lumbar arteries was performed whenever possible. In-hospital mortality was 16.7% in group A and 15.8% in group B. Total aortic clamp time and operating time were only 84 and 437 min in group A, compared with 134 and 589 min in group B. Three patients showed postoperative paraplegia in group B. No spinal cord injury occurred in patients whose artery had been detected preoperatively. Preoperative anatomic delineation of the Adamkiewicz artery by MRA can reduce risk of ischemic injury to the spinal cord and decrease operating time required for repair of thoracoabdominal aortic aneurysms.

Abstract
BACKGROUND The outcome of thoracoabdominal aortic aneurysm repair through redo-left thoracotomy after operations for descending thoracic aortic aneurysms was investigated. METHODS Between May 1982 and March 2003, 100 patients underwent thoracoabdominal aortic aneurysm repair in elective surgery without profound hypothermic circulatory arrest. Thirty of these patients had previously undergone operations for descending thoracic aortic aneurysms. To evaluate the influence of previous descending thoracic aortic aneurysm repairs on the results of thoracoabdominal aortic aneurysm replacements, patients were divided into two groups: (1) patients who had previously undergone descending thoracic aortic aneurysm repair (group I; n = 30), and (2) patients who had not previously undergone descending thoracic aortic aneurysm repair (group II; n = 70). RESULTS The distal aortic perfusion time and operation time were both longer in group I than in group II, but there was no significant difference between the two groups in total selective visceral and renal perfusion time or aortic clamp time. In-hospital mortality rates were 13% in group I and 19% in group II (p = 0.52). Major postoperative complications included paraplegia (10% of patients in group I and 4.3% of patients in group II; p = 0.36), renal failure requiring hemodialysis (20% of patients in group I and 11% of patients in group II; p = 0.35), respiratory failure (30% of patients in group I and 19% of patients in group II; p = 0.22). CONCLUSIONS Previously descending thoracic aortic aneurysm and redo-left thoracotomy do not adversely affect the outcome of thoracoabdominal aortic aneurysm repair.

Abstract
The relationship of the conduit to the sternum is crucial in the Rastelli operation. Right-sided conduits are more greatly affected by sternal compression than left, since the position of the right ventricular infundibulum is more anterior. A 37-year-old woman developed right ventricular outflow tract obstruction, left ventricular outflow tract obstruction, and aortic valve regurgitation secondary to infective endocarditis 15 years after Rastelli repair for double-outlet right ventricle (SDL). We enlarged the ventricular septal defect, performed intraventricular rerouting and aortic valve replacement, and reconstructed the valved conduit using a Carpentier-Edwards conduit. The old conduit was densely adherent to the sternum. Subaortic stenosis was caused by a narrow fibromuscular ridge associated with a bulge of the underlying septal muscle. The patient's recovery was uneventful. She is alive and well without any complaints 1 year after surgery.

Abstract
We describe here a case with a large bronchogenic cyst treated by surgical resection, who presented with evidence of left atrial overload on electrocardiogram (ECG). The 50-year-old male patient presented with the chief complaint of heaviness in the chest on exertion. An ECG revealed evidence of left atrial overload, and echocardiography and imaging revealed a mass having a maximum diameter of 9 cm on the cranial aspect of the left atrium, caudal to the tracheal bifurcation. The patient was treated by surgical resection of the cystic mass via right anterolateral thoracotomy. His postoperative course was satisfactory and the patient was relieved of his main symptom.

Abstract
BACKGROUND The aim of this study is to review the outcome of reoperation for severe tricuspid regurgitation after repair of tetralogy of Fallot. METHODS Between 1972 and 2000, 12 patients underwent reoperation on the tricuspid valve after total correction of tetralogy of Fallot. The mean age at the time of reoperation was 17 years (range, 1 to 39 years). The mean interval between the initial correction and the reoperation was 7.8 years (range, 10 days to 19 years). The functional class was New York Heart Association class II in 2 patients and class III or IV in 10. Six patients underwent tricuspid valve repair, and the others underwent tricuspid valve replacement. RESULTS Hospital mortality was 16.7% (2/12). Three patients (30%, 3/10) required a second reoperation 1.6, 9.2, and 15.6 years after the most recent reoperation with no deaths. The reasons for second reoperation were failure of the tricuspid valve repair in two and a thrombosed valve in one. There were two late deaths. Mean overall event-free actuarial survival at 10 years was 46.3%. CONCLUSION Reoperation for severe tricuspid regurgitation after total correction of tetralogy of Fallot was associated with a high operative mortality and disappointing long-term results. Tricuspid regurgitation after corrective surgery for tetralogy of Fallot must be diagnosed promptly and cured, as tolerance is poor because of postoperative right ventricular insufficiency.

Abstract
The purpose of this study was to evaluate the safety of profound hypothermic circulatory arrest with heparin-coated circuits and low dose systemic heparinization in the treatment of cerebral aneurysms. Surgery for giant intracranial aneurysms not operable using standard neurosurgical techniques was performed in 8 patients. All patients were placed on cardiopulmonary bypass using the closed-chest technique, except for the first patient who underwent open-chest bypass. Heparin was administered systemically (3,000 IU) and into the circuit (1,500 IU). Total circulatory arrest was begun at 20 degrees C. The D-dimer, alpha2 plasmin inhibitor-plasmin complex, thrombin-antithrombin III, and beta-thromboglobulin concentrations were measured to evaluate the changes in the coagulation and fibrinolytic systems during bypass. There were no neurologic or cardiac complications. None of the indicators of platelet activation, coagulation, or fibrinolysis were elevated. Hypothermic circulatory arrest combined with heparin-coated circuits and low dose systemic heparinization is safe for use in neurosurgery.

Abstract
A 24-year-old woman had undergone valvuloplasty of the aortic valve and external reinforcement of an aneurysm of the ascending aorta during the active phase of Takayasu arteritis 1 year prior to admission to our hospital. On examination, she was diagnosed as having a large false aneurysm of the ascending aorta with annuloaortic ectasia and severe aortic regurgitation, bilateral common carotid artery aneurysms with a left internal carotid artery saccular aneurysm, and bilateral subclavian artery and right vertebral artery obstructions due to Takayasu arteritis. Because of the risk of rupture, surgical intervention was carried out in spite of the fact that aortitis was in the active phase.

Abstract
A reoperation to upsize the conduit placed at infancy for the repair of an anomalous origin of the right pulmonary artery (AORPA) was successfully performed in an 8-year-old girl because of an elevated right ventricular pressure and a reduced right pulmonary blood flow. Although primary direct anastomosis is essential for AORPA, one should not hesitate to perform a conduit repair (interposition with a tube prosthesis) on an infant with AORPA whose right pulmonary artery is distant from the main pulmonary artery, because a reoperation can safely be performed even in cases where the conduit is relatively narrow as the patient grows. This is the first report of a reoperation, including a complete replacement of the conduit, after an initial conduit repair for AORPA.

Abstract
BACKGROUND We reviewed the outcomes of double-chambered right ventricle repair. METHODS Between 1969 and 1998, 40 patients underwent surgical repair of a double-chamber right ventricle. The patients ranged in age from 3 months to 52 years (mean, 12.8 +/- 11.6 years). Right ventricular outflow tract pressure gradients were from 20 to 170 mm Hg (mean, 65.0 +/- 38.5 mm Hg) An associated ventricular septal defect was present in 27 patients (67.5%). Four patients were older than 30 years of age. RESULTS There were no hospital or late deaths. Mean postsurgical follow-up was 16.5 +/- 8.9 years (range, 2.5 to 31 years). No patient required further surgery to relieve obstruction of right ventricular outflow tract. CONCLUSIONS Surgical repair of a double-chambered right ventricle yields excellent hemodynamic and functional results over both the short and long term.

Abstract
Thirty surviving patients after corrective surgery for tetralogy of Fallot with right ventricular outflow tract reconstruction (RVOTR) using monocusp ventricular outflow patch (MVOP) were reviewed retrospectively to determine the long-term results. The age at operation ranged from 2 to 55 years with a mean of 19 years, and follow-up extended to 18.2 years (cumulative: 345.4 patient-year). There were 4 late deaths (1.2% per patient-year), and the cumulative survival rate was 85.3% at 18 years after the corrective surgery. Eight patients (2.3% per patient-year) required intracardiac reoperations mostly resulted from problems after RVOTR with MVOP, such as recurrent stenosis of right ventricular outflow tract (3 cases) or pulmonary valvular incompetence (4 cases). In addition, one patient underwent balloon angioplasty for the recurrent stenosis located in the distal end of MVOP. Freedom from surgical or catheter reintervention for the MVOP-related complication was 60.6% at 18 years after the corrective surgery. MVOP caused compression of the pulmonary artery at the distal end of the anastomosis and reoperation in a younger patients quite early after the corrective surgery. Like other transannular patches, tissue failure and degeneration of MVOP were inevitable, and resulted in severe pulmonary valvular incompetence that required the valve replacement in 4 patients (1.3% per patient-year). Freedom from pulmonary valve replacement was 71.2% at 18 years after the corrective surgery. As long-term results, our experiences emphasize the need for an innovative transannular patch that possesses significantly better long-term durability.

Abstract
Infection of a retained permanent epicardial pacemaker lead rarely causes mediastinal infection. A 21-month-old boy who had undergone an arterial switch operation at day 6 of life presented with mediastinal infection 3 months after removal of the generator. Removal of the infected pacemaker leads with the inflammatory granuloma was performed under extracorporeal circulation. The mediastinal infection developed from the retained epicardial pacemaker lead infection.

Abstract
The left brachiocephalic vein is found in an anomalous position less frequently than the superior vena cava or azygous channels in thoracic venous systems. We experienced a rare case of anomalous left brachiocephalic vein which was clearly demonstrated by spiral computed tomography (3D-CT). Although the malformation in itself seems to be of no functional importance, we assessed its importance in terms of associated conditions and its relevance to subsequent operations.

Abstract
BACKGROUND As patients began to survive for longer periods following modified Fontan operations (conventional atrio-pulmonary connection), the late morbidity after this procedure became increasingly apparent. The purpose of the present study was to evaluate late sequelae of modified Fontan operations in long-term survivors (n=14) at our institute. METHODS AND RESULTS The cohort consisted of patients who underwent a modified Fontan operation between 1981 and 1990. Thus, all patients were examined at least 10 years postoperatively in this study. Early mortality, within 30 days of the operation, was 17.6% (three of 17 patients died from low output syndrome). Excluding these early deaths, the cumulative survival rate at 5 and 10 years was 100 and 79%, respectively. Arrhythmias including atrial fibrillation or flutter were the main late causes of morbidity. The arrhythmia-free rate at 5 and 10 years was 77 and 50%, respectively. Although the quality of life was considered good because all patients (n=11) who survived for 10 years or more were in class I or II according to the New York Heart Association classification, most of them in fact suffered from potentially life-threatening arrhythmias. CONCLUSIONS Meticulous attention to and utilization of established treatment strategies for arrhythmias including anti-arrhythmics, anticoagulants, catheter ablation or re-operation converting the circulation to the total cavopulmonary connection must be considered in long-term survivors following the modified Fontan operation. The fact that no one knows when the thrombogenic arrhythmias occur suggests anticoagulants should be initiated in the early postoperative period.

Abstract
We describe two cases of successful management by native valve salvage of an uncommon tricuspid valve regurgitation following blunt chest trauma. The two patients were diagnosed 13 years and six years, respectively, after the trauma. In both cases, tricuspid valvular insufficiency was caused by anterior leaflet prolapse due to chordal and papillary muscle rupture associated with annular dilatation. Operative repair with implantation of artificial chordae, papillary muscle reinsertion and ring annuloplasty resulted in complete recovery. The need for increased awareness of this lesion in patients suffering blunt chest trauma is emphasized, and the relevant literature reviewed.

Abstract
Diaphragmatic action potentials (DAPs) were mapped on the thorax bilaterally in 16 neurologically normal infants and 8 boys aged 1 to 4 years during artificial ventilation after thoracic surgery. Transcutaneous stimulation was used to activate the phrenic nerve at the supraclavicular fossa at the end of an artificial inspiration. The DAPs were of positive polarity and were recorded on the ipsilateral anterolateral chest wall over the sixth to the eighth intercostal spaces, with a maximal peak at the seventh intercostal space. The DAP latencies gradually decreased from 6 to 8 ms at birth to about 5 ms at the age of 1 year, despite an increase of conduction distance. Statistical analyses revealed that DAP amplitude did not correlate with age. The latencies and amplitudes of the DAPs displayed little interside variation. The results are valuable not only as a reference for the diagnosis of patients with phrenic nerve palsy, but also as an indicator of the normal development of the phrenic nerve.
