ObjectiveTo investigate the diagnosis and management of penile fracture.

METHODSFrom June 1993 to May 2017, 46 cases of penile fracture were treated in our hospital, averaging 33.5 (25－42) years of age and 3.45 (1－10) hours in duration, of which 41 occurred during sexual intercourse, 4 during masturbation and 1 during prone sleeping, 4 with hematuria, but none with dysuria or urethral bleeding. Hematoma was confined to the penis. Emergency surgical repair was performed for all the patients, 45 under spinal anesthesia and 1 under local anesthesia, 16 by coronal proximal circular incision and the other 30 by local longitudinal incision according to the rupture location on ultrasonogram. The tunica albuginea ruptures averaged 1.31 (0.5－2.5) cm in length, which were sutured in the "8" pattern for 6 cases and with the 3－0 absorbable thread for 18 cases. The skin graft or negative pressure drainage tube was routinely placed, catheters indwelt, and gauze used for early pressure dressing. In the recent few years, elastic bandages were employed for 3－5 days of pressure dressing and antibiotics administered to prevent infection. The stitches and catheter were removed at 7 days after surgery.

RESULTSShort-term postoperative foreskin edema occurred in 14 of the 16 cases of circular degloving incision, but no postoperative complications were observed in any of the cases of local incision. Twenty-eight of the patients completed a long-term follow-up of 49.4 (10－125) months, which revealed good erectile function, painless erection, and satisfactory sexual intercourse.

CONCLUSIONSFor most penile fractures, local longitudinal incision is sufficient for successful repair of the tunica albuginea, with mild injury, no influence on the blood supply or lymph reflux, and a low rate complications. It therefore is obviously advantageous over circular degloving incision except when the cavernous body of urethra is to be explored, which necessitates circular degloving incision below the coronal groove.

PURPOSE: Neonatal neuroblastoma (NBL) is the most common malignant tumor in neonates, but there have been few studies about it. The purpose of this study was to investigate the clinical features of NBL and to compare prenatal and postnatal diagnosed groups. METHODS: Nineteen patients who were diagnosed with NBL prenatally or within 28 days after birth from February 1986 to February 2013 in Seoul National University Hospital were enrolled in the study. The patients were categorized according to the International Neuroblastoma Staging System (INSS) and Children's Oncology Group (COG). Retrospective medical-record reviews were performed on these patients. The operative date, complication, pathological stage, and overall survival of the prenatally diagnosed group and the postpartum diagnosed group were compared. RESULTS: Tumor was detected via prenatal ultrasonography in 8 patients (42.1%), and 11 patients (57.9%) were diagnosed within 28 days after birth. Based on INSS, the patients were divided into the stage I (n=8), stage II (n=1), stage III (n=3), stage IV (n=4), and stage IVs (n=3) groups, respectively. Based on COG, on the other hand, the patients were divided into the low-risk (n=8), intermediate-risk (n=8), and high-risk (n=3) groups. The postoperative complication rate was 29%. One patient died from complications from chemotherapy. The other 18 patients' mean follow-up period was 77.7 months. The differences between the postoperative complication rate, proportion of early-stage tumor, and overall survival of the prenatal and postnatal groups were not statistically significant (p=0.446, p=0.607, p=0.414). CONCLUSION: NBL showed favorable outcomes but relatively higher postoperative complications. There seem to be no significant statistical differences in the postoperative complications, proportion of early-stage tumor, and overall survival between the prenatally diagnosed group and the postpartum diagnosed group.

Optical coherence tomography (OCT) has been recently applied to investigate coronary artery disease in interventional cardiology. Compared to intravascular ultrasound, OCT is able to visualize various vascular structures more clearly with higher resolution. Several validation studies have shown that OCT is more accurate in evaluating neointimal tissue after coronary stent implantation than intravascular ultrasound. Novel findings on OCT evaluation include the detection of strut coverage and the characterization of neointimal tissue in an in-vivo setting. In a previous study, neointimal healing of stent strut was pathologically the most important factor associated with stent thrombosis, a fatal complication, in patients treated with drug-eluting stent (DES). Recently, OCT-defined coverage of a stent strut was proposed to be related with clinical safety in DES-treated patients. Neoatherosclerosis is an atheromatous change of neointimal tissue within the stented segment. Clinical studies using OCT revealed neoatherosclerosis contributed to late-phase luminal narrowing after stent implantation. Like de novo native coronary lesions, the clinical presentation of OCT-derived neoatherosclerosis varied from stable angina to acute coronary syndrome including late stent thrombosis. Thus, early identification of neoatherosclerosis with OCT may predict clinical deterioration in patients treated with coronary stent. Additionally, intravascular OCT evaluation provides additive information about the performance of coronary stent. In the near future, new advances in OCT technology will help reduce complications with stent therapy and accelerating in the study of interventional cardiology.

OBJECTIVE: The aim of this study was to evaluate the frequency of postoperative biliary stricture and its risk factors in patients undergoing surgery for type I choledochal cyst. MATERIALS AND METHODS: A total of 35 patients with type I choledochal cyst underwent laparoscopic cyst excision and Roux-en-Y hepaticojejunostomy between August 2004 and August 2011. Their medical records and radiologic images (including endoscopic retrograde cholangiopancreatography, magnetic resonance cholangiopancreatography, pancreatobiliary computed tomography, or ultrasound) were retrospectively analyzed to evaluate the frequency of postoperative biliary stricture and its risk factors. RESULTS: Postoperative biliary stricture was found in 10 (28.6%) of 35 patients. It developed more frequently in patients with type Ia choledochal cyst (53.8%, 7 of 13 patients) than in patients with type Ic choledochal cyst (13.6%, 3 of 22 patients), which was statistically significant (p = 0.011). There were no significant associations between other factors and postoperative biliary stricture. CONCLUSION: Type Ia is a risk factor of postoperative anastomotic stricture. Therefore, preoperative radiologic subclassification of type Ia and Ic may be useful in predicting postoperative outcomes of choledochal cysts.

Primary hyperparathyroidism due to ectopic parathyroid adenomas can pose diagnostic and management challenges, especially when imaging studies have localised the lesions to different sites. We report a case of symptomatic hypercalcaemia due to a mediastinal parathyroid adenoma. Ultrasonography identified a nodule posterior to the right thyroid gland. However, computed tomography and technetium-99m sestamibi scintigraphy revealed an ectopic parathyroid adenoma located in the anterior mediastinum. The adenoma was successfully removed through a median sternotomy. However, postoperatively, the patient developed prolonged symptomatic hypocalcaemia, possibly due to suppression of the normal parathyroid gland function, although the presence of concomitant hungry bone syndrome was possible. The histopathology of the mediastinal mass was consistent with a parathyroid adenoma.

Systemic infection with Aspergillus is an opportunistic disease that affects mainly immunocompromised hosts, and is associated with a high mortality rate. It typically occurs in patients with several predisposing factors, but Aspergillus endocarditis of native valves is rare and experience in diagnosis and treatment is limited. We report a case of native valve endocarditis caused by Aspergillus. A 35-yr-old male patient who underwent pericardiocentesis four months previously for pericardial effusion of unknown etiology presented with right leg pain and absence of the right femoral artery pulse. Cardiac echocardiography revealed severe mitral insufficiency with large mobile vegetations, and computed tomographic angiography showed embolic occlusion of both common iliac arteries. We performed mitral valve replacement and thromoembolectomy, and Aspergillus was identified as the vegetation. We started intravenous amphotericin B and oral itraconazole, but systemic complications developed including superior mesenteric artery aneurysm and gastrointestinal bleeding. After aggressive management, the patient was discharged 78 days post surgery on oral itraconazole. He was well at 12 months post discharge but died in a traffic accident 13 months after discharge.

OBJECTIVETo evaluate the predictive value of portal vein flow rate preoperative for portal vein thrombosis (PVT) after periesophagastric devascularization in hepatitis B cirrhosis-related portal hypertension.

METHODSFrom January 2007 to July 2008, 45 patients with portal hypertension caused by hepatitis B cirrhosis were performed splenectomy with peri-esophagogastric devascularization in the same medical group in West China Hospital of Sichuan University. The portal vein flow rate and the diameter of portal vein were measured with doppler sonography respectively before and after the operation. At the same time, the level of PT and PLT were detected. The weight of spleens were measured after operation.

RESULTSThirteen cases suffered from PVT postoperatively. Portal vein flow rate was significantly lower in patients with PVT postoperation than that in patients without PVT (P < 0.01). In patients with PVT (n = 13) postoperation, the preoperative portal vein flow rate was (19.5 +/- 5.3) cm/s. Among the 13 cases, there were 12 cases whose flow rate were lower than 25 cm/s, and 1 case whose flow rate was 32. 3 cm/s; In patients without PVT (n = 32), the preoperative portal vein flow rate was (9.6 +/- 8.0) cm/s. In patients with lower rate (n = 17), the incidence rate of PVT was 70.6%; in patients with higher rate (n = 28), the incidence rate of PVT was 3.6%. The incidence rate of PVT in patients with lower rate was significantly lower than patients with higher rate (P < 0.01). The diameter of portal vein in patients with PVT was significantly wider than patients without PVT. The diameter of portal vein was negative correlative with the portal vein flow rate. The value 25 cm/s was of diagnostic efficiency, the sensitivity was 92.3%, and specificity was 70.6%.

CONCLUSIONSThe portal vein flow rate preoperative can be used as an early predictor of portal vein thrombosis after periesophagastric devascularization in hepatitis B cirrhosis-related portal hypertension to give a guide to clinical work.

Stump appendicitis is an acute inflammation of the residual appendix and a rare complication after an appendectomy. Although the signs and symptoms do not differ from acute appendicitis, the diagnosis is often not considered because of the past surgical history. Only a small number of stump appendicitis cases have been reported, but there has been no report of stump appendicitis in Korea. Herein, we report a case of stump appendicitis. A 28-year-old female was admitted to our hospital due to right lower quadrant abdominal pain. Fifteen months ago, the patient had a laparoscopic appendectomy under the diagnosis of an acute appendicitis, but she subsequently suffered from intermittent abdominal pain and fever. Abdominal ultrasonography and CT scan showed an inflamed appendiceal stump. Laparoscopic stump appendectomy was done and the biopsy revealed stump appendicitis.

PURPOSE: There is no agreement concerning the management of ureteropelvic junction obstruction(UPJO) in children. We reviewed our experience over 10 years for children with UPJO to analyze the clinical course and desirable treatment modality. MATERIALS AND METHODS: We reviewed the medical records of 80 consecutive children with UPJO and they were diagnosed between December 1994 and November 2004. There were 67 boys and 13 girls. A total of 94 kidneys in 80 patients were evaluated with urinalysis, ultrasonography, diuretic renogram and (99m)Tc-DMSA renal scanning. The natural progression of disease, the management method and the perioperative outcomes were retrospectively compared. RESULTS: Fifty of the 80 patients were prenatally diagnosed by fetal hydronephrosis or who were diagnosed at younger than 1 year(group A), and 30 patients were diagnosed at older than 1 year(group B). In group A, 18 patients underwent dismembered pyeloplasty before 1 year(A1) and 2 patients underwent nephrectomy due to severe deterioration of their renal function(<5%). Among the other 30 patients, delayed pyeloplasties were performed in 20 patients(A2) and 10 patients were managed conservatively(A3). In group B, 22 patients underwent pyeloplasty immediately (B1), and the other 8 patients underwent delayed pyeloplasty(B2). On the comparison of renal functional change among the patients in group A, the A1 patients had better renal functional improvement than the A2 and A3 patients. However, there was no statistical difference between the patients in B1 and B2. The postoperative complication rates were not significantly different in all the groups. CONCLUSIONS: It is thought that early operation is more effective for improving the renal function in children younger than one year.
