We report a patient with Leriche syndrome who had ileal conduit and a right lower quadrant stoma. A 47-year-old man with a history of bladder cancer had undergone radical total cystectomy with formation of an ileal conduit and right lower quadrant stoma 2 years previously. CT scanning revealed total occlusion of the distal aorta. He experienced right lower leg pain after 30 m of walking. Through a repeat midline laparotomy incision, the abdominal aorta was dissected with a transperitoneal approach. To avoid dissection around the ileal conduit, the retroperitoneum was incised (open) at the right of the ascending colon and at the left of the sigmoid colon. A prosthetic graft (Interguard 14×7 mm) was pulled bilaterally through these incisions, to the external iliac arteries. Abdominal aorto-bilateral external iliac artery bypass grafting was performed and the patient was discharged without complications on the 15th postoperative day.

Ankylosing spondylitis is chronic, progressive, inflammatory disease involving the spine, peripheral joints, and periarticular structures. Cardiac abnormalities associated with ankylosing spondylitis are well recognized, but a case with DDD pacemaker implantation for complete atrioventricular block and aortic valve replacement for aortic regurgitation has not been previously reported. We report a case of a 66-year-old man with ankylosing spondylitis who was successfully treated by DDD pacemaker implantation for complete atrioventricular block and aortic valve replacement for severe aortic regurgitation.

Objective：The aim of this study was to examine the relationships between the timing of gait acquisition and the length of hospitalization, and to clarify the differences in background factors and functional recovery during the early postoperative period and their effect on the variability in gait acquisition.
Methods：We recruited 148 patients who underwent total knee arthroplasty (TKA) at three hospitals. The participants were divided into two groups on the basis of the number of days needed to achieve independent gait at ≤14 days after surgery (group A) and ＞14 days after surgery (group B). We compared the background factors between the two groups. Additionally, we compared the preoperative and postoperative function in each group.
Results：We observed a significant positive correlation between the number of days needed to achieve independent gait and the length of hospitalization. In group A, the significant background factors were younger age and higher preoperative activity level. In group A, compared with the level of preoperative function, the postoperative maximum knee extension angle on the operated side and pain had significantly improved. In both groups, the postoperative knee extensor strength on the operated side, knee extensor strength on the nonoperated side, knee flexion strength on the operated side, maximum knee flexion angle on the operated side, and walking speed were significantly reduced.
Conclusion：During early rehabilitation, it is necessary to consider the age and previous activities of patients. In addition, we suggest that early rehabilitation with a focus on reducing pain by alleviating inflammation and improving maximum knee extension angle on the operated side may be effective for fast acquisition of gait.

Objective：To elucidate factors associated with physical function and clarify the actual condition of functional deterioration in patients with knee osteoarthritis (OA) prior to total knee arthroplasty (TKA)．

Methods：We enrolled 467 patients with severe knee OA and preoperatively assessed the following parameters：background factors (sex, age, BMI, K-L grade, and pain) and physical function (muscle strength of knee extensors and flexors, and knee joint angles). A multiple regression analysis was performed to determine the relationship between the independent background factors and dependent physical functions. The median of preoperative function based on selected factors of physical function was calculated.

Results：Based on the multiple regression analysis, sex, BMI, K-L grade, and pain statistically significantly correlated with muscle strength of knee extensors and flexors. Sex and BMI statistically significantly correlated with knee joint flexion angle. K-L grade statistically significantly correlated with knee joint extension angle. The median of muscle strength for knee extension was 0.98/0.92 Nm/kg (Grade 3/Grade 4) for males and 0.70/0.59 Nm/kg for females. The median of muscle strength for knee flexion was 0.53/0.45 Nm/kg for males, 0.36/0.30 Nm/kg for females. The median for knee joint flexion angle was 130° for males and 120° for females. The median for knee joint extension angle was -5°/-10° (Grade 3/Grade 4)．

Conclusion：We clarified the degree of muscle strength and range of motion before TKA in patients with knee OA. We believe that the findings obtained in this study will contribute to explaining the functional deterioration of patients with knee OA.

This study aimed to clarify whether continuous hemodiafiltration (CHDF) or hemodialysis (HD) was more effective after open heart surgery in dialysis patients. We evaluated 48 consecutive hemodialysis patients (28 men and 20 women, mean age : 68±10 years) who underwent coronary artery bypass grafting (CABG) and/or aortic valve replacement (AVR) between January 2003 and December 2008. The patients were divided into 2 groups according to their postoperative dialysis treatment either continuous hemodiafiltration (CHDF) (CHDF group, n=36) or hemodialysis (HD) (HD group, n=12). Surgery in the CHDF group included 13 concomitant operations, 16 CABGs and 7 AVRs. There was only 1 concomitant surgery in the HD group, and there were 6 CABGs and 5 AVRs. There was no difference between the 2 groups regarding operation time, aortic clamp time, cardiopulmonary bypass time or intraoperative volume balance. CHDF was started significantly earlier than HD (8.0±5.8 vs. 21.0±1.0 h, p <0.01), which resulted in the removal of a greater volume of body fluid, during the first postoperative 24 h in the CHDF group (1,200±110 vs. 550±50 ml, p <0.01). However, there was no difference between the 2 groups regarding the amount of postoperative chest drainage. There were 6 hospital deaths in the CHDF group (17% ; 3 heart failures, and 1 each of pneumonia, arrhythmia and massive intestinal necrosis). There was also 1 hospital death in the HD group (8.3% ; heart failure). Most of the hospital deaths occurred after concomitant operations (6/7, 86%). It is beneficial to start CHDF soon after open heart surgery in hemodialysis patients.

Objective:We successfully treated a patient suffering from pain and numbness in the waist and lower limbs with phobia. Sedative acupuncture treatment was performed in addition to somatic treatment.
Case:A 64-year-old woman complained mainly of pain and numbness in the right waist and the lower limbs and had a sense of fear. Following the postoperative pain of lumbar disk herniation (L4-L5) in X-14 year, dorsal positioning without grasping anything frequently triggered a sense of fear with a scary feeling that her body was suspended in midair, which could not be alleviated by medication. As the symptoms in the waist and lower limbs recurred due to a fall in January of X year, she consulted an orthopedist in April. She was given a diagnosis of lumbar disk hernia (L5-S1) and hospitalized. Since the symptoms sustained, she consulted the department of acupuncture attached to the Kansai University of Health Sciences Clinic in November. The sense of fear triggered by dorsal position in the acupuncture treatment interfered with the treatment. When she was referred to the department of psychosomatic medicine, the diagnosis of "Other types"of the DSM-IV "300.29 specific phobia"was given. While low-frequency acupuncture electrotherapy on the same side and the same level as the hernia was provided, we applied sedative acupuncture treatment once a week 30 times using the following acupuncture points:GV23;PC6;CV17;and CV6. Before and after every acupuncture treatment after the 10th, the symptoms were evaluated with Finger Floor Distance (FFD), Visual Analogue Scale (VAS) of pain and mood (feelings) and State-Trait Anxiety Inventory (STAI).
Results:The sense of fear during the acupuncture treatment slowly decreased after the 14th treatment. Decreases in FFD, VAS for pain and mood (feelings), and state anxiety score of STAI were observed. The pain and the numbness in the waist and the lower limbs decreased in parallel with the sense of fear. Furthermore, the dosage of hypnotic agent decreased gradually as sleep improved.
Conclusion:Pain and numbness in the waist and the lower limbs with phobia were relieved by sedative acupuncture treatment.

We successfully performed aortic root replacement in an asymptomatic 52 year-old man with dilatation of the Valsalva sinuses (75 mm). The patient had previously undergone a radical operation for the tetralogy of Fallot at 13 years of age and AVR at 46 years of age. Massive bleeding occurred in the lungs after weaning from CPB. Emergency bronchoscopy revealed that the bleeding came from the right middle and lower lobes. The bleeding was stopped conservatively on POD 3 ; however, V-V ECMO was started on POD 5 because of severe hypoxia. ECMO was successfully weaned on POD 11 and he discharged on POD 59. The presence of developed bronchial collaterals and barotrauma during the operation were speculated the causes of the bleeding from the right lung.

Bicuspid aortic valve (BAV) is one of the more common congenital anomalies. It is well known that the ascending aorta and aortic root sometimes dilate in patients with BAV, even when the valve function is normal. We examined the morphological type and histological features of the dilated ascending aorta in patients with BAV. Of 276 patients who underwent aortic valve replacement (including coronary artery bypass grafting) from 2004 onwards, 60 (21.5%) with BAV were included in this study. The type of BAV was defined according to the Sievers classification. Type 1 BAV was the most common, and enlargement of the ascending aorta (≥45 mm) was the most common in the L/R type of BAV (48%). The morphology of the dilated ascending aortic wall was evaluated using three-dimensional CT angiography. The majority of dilations were asymmetric, but dilation was symmetric in the patient with dilation of the aortic root. Histological examination graded cystic medial necrosis of the ascending aortic walls using the aortic wall score. All patients with BAV had degeneration of the aortic wall, even when there was no dilation. The aortic walls of patients with dilated aortic roots showed advanced degeneration compared with the aortic walls of other patients. Therefore, aggressive root replacement may be appropriate, when the root is mildly dilated in patient with BAV.

Left-sided gallbladder is a rare finding that is mostly discovered incidentally during surgery and is often associated with anatomic anomalies. We herein report a case in which laparoscopic cholecystectomy and common bile duct exploration were achieved for an 89-year-old female patient with left-sided gallbladder. Surgery was carried out using our usual trocar position.Calot triangle was covered by the body of the gallbladder and could not be detected. We dissected the gallbladder from the fundus towards the neck. The cystic duct joined the common bile duct from the right side, and common bile duct exploration was performed routinely without perioperative comorbidities. Although the preoperative diagnosis rate is low and the risk of intraoperative bile duct injuries in patients with left-sided gallbladder is high, laparoscopic cholecystectomy and common bile duct exploration can be safely performed by understanding the location and bifurcation of the cystic duct.
