A sinus between the colon and a retroperitoneal abscess is a rare entity that usually occurs as a complication of a primary condition such as Crohn's disease, radiation enteritis, or diverticular disease. Herein, we report a 72-year-old woman with a retroperitoneal abscess and a sinus formation between the abscess and the colon after an iatrogenic injury to her left colon. The retroperitoneal abscess was detected 1 week after the patient had undergone a left nephroureterectomy for recurrent ureteral cancer. The patient's general performance status allowed conservative management with antibiotics and percutaneous drainage. The abscess resolved, and the sinus closed after 3 weeks of treatment. In the absence of surgical pathology in the colon, and if the patient's general condition is good enough to tolerate conservative management, treatment using antibiotics plus percutaneous drainage is effective for cases of retroperitoneal abscess with a sinus between the colon and abscess.

We aimed to investigate the relationship between the neutrophil to lymphocyte ratio (NLR) and postoperative length of hospital stay. In addition, the impact of radiological and histopathological findings on hospital stay was also evaluated.

Aim of this study was to evaluate the characteristic features of patients with mesothelial cyst of the round ligament of the uterus and the incidence of this entity. This was a retrospective review of 3065 patients who underwent inguinal exploration for groin mass from 1998 to 2013. Clinical, radiological and histopathological features of patients with a diagnosis of mesothelial cyst of the round ligament were analyzed. Of the 405 female patients reviewed 9 mesothelial cysts of the round ligament were identified (2.2%). The median age was 37 (range 19-82 years). In all patients the groin mass was manually irreducible on physical examination. The lesions were on the right side in 6 (66.6%) patients. These were identified before surgery in 4 (all by groin ultrasonography). Three were misidentified as a hernia before surgery. The remaining 2 (22%) had both hernia and the mesothelial cyst of the round ligament. The cysts were identified after surgery at the time of histopathological examination in these two patients. In all patients histopathological examination revealed multilobular cystic lesion lined by a single layer of mesothelial cells. Cystic lesions arising from the round ligament were identified and excised along with the round ligament in 7 patients. In the remaining 2, a hernia repair was also performed. There was no recurrence at follow-up. Mesothelial cysts of the round ligament are rare. They are easily misidentified as groin hernia. An accurate diagnosis requires a high index of suspicion and is greatly aided by preoperative imaging studies.

Diastasis recti abdominis is a condition defined as the separation between the rectus abdominis and the linea alba, which leads to weakness in the abdominal muscles. Diastasis may be slight or severe, sometimes resulting in herniation of the abdominal viscera. Following childbirth, most women develop some extent of muscle separation in the postpartum period. However, if the diastasis recti abdominis in the postpartum period remain severe, it should be corrected to prevent concurrent abdominal hernia, strangulation or incarceration. We herein present two Korean cases of postpartum women with severe diastasis recti abdominis with abdominal hernia; it is the first report of its kind from Korea. Two women were referred to our clinic with severe abdominal bulge. Computerized tomography scan showed widening of the linea alba with abdominal hernia. The standard abdominoplasty with multiple wide longitudinal plications of the abdominal wall was performed in each patient under general anesthesia. There was no recurrence of diastasis recti abdominis or abdominal hernia during follow-up periods. The application of abdominoplasty in postpartum women with severe diastasis recti abdominis with abdominal hernia is thus considered to be an efficient management option. We hope these cases can provide a reference for the treatment of similar situations.

Primary endpoint is to determine whether intraoperative steroid affect post-thyroidectomy recurrent laryngeal palsy or not Background: Recurrent laryngeal nerve (RLN) palsy is an important complication of thyroid surgery. Injuries can either be permanent or temporary. Prevention or shortening the recovery period of temporary palsies is an area of interest. Some surgeons prefer to use corticosteroids for this purpose as is used for facial nerve palsies although there are conflicting data in the literature. We aimed to investigate the efficacy of perioperative single dose methylprednisolone on RLN function.

1-INTRODUCTION: The Lichtenstein hernia repair is associated with low recurrence rates and short operation times, and can be performed under local anaesthesia. Thus, this is among the most-preferred methods used in recent years. Our objective was to explore the same-day discharge rates, and the causes of delayed discharge and re-admission to hospital, of patients treated using the Lichtenstein repair method, to evaluate the feasibility of performing same-day hernia surgery in clinical practice. 2.

One hundred and sixty-two patients with GERD were treated surgically with LNF from October 2006 to March 2010. Diagnoses were made by using upper gastrointestinal system (GIS) endoscopy and 24-hour pH monitoring, and all the patients underwent routine LNF surgery. The patients were questioned regarding complaints and proton pump inhibitor (PPI) usage during the postoperative period, and forty patients who had postoperative GIS symptoms were included. Upper GIS endoscopy with antral biopsy for Helicobacter pylori (HP) identification and multichannel intraluminal impedance pH(MII-pH) monitoring were applied Results:The median postoperative follow-up time was 1.84 ± 0.850 (0.29-3.48) years. PPI treatment frequency was 37.5% (15 patients) in the 40 symptomatic 40 patients, or 9.26% in all 162 patients who were operated on. The reason for PPI usage in three patients (7.5%) was regarded as recurrence. HP positivity was 67.5% in the symptomatic patients and 73.3% in the PPI treated group; 40% (six patients) recovery was achieved in the HP (+) patients by using an HP eradication treatment protocol. The operated patients displayed statistically significant results in increased quality of life (p = 0.001) and lowered DeMeester scores (p = 0.000) during the postoperative period when compared to preoperative period.

Based on the anti-inflammatory, antioxidant and anti-apoptotic properties of DEX, the present study was conducted to investigate the possible radioprotective effects of DEX against hepatic radioiodine (I-131) toxicity.

Intestinal obstruction caused by primary intraperitoneal hernia is infrequent and difficult to diagnose. Incorrect diagnosis and delayed surgical treatment will lead to serious consequences. We report a rare case of a 62-year-old Chinese woman with strangulated lesser omentum hiatus hernia. Contrast-enhanced abdominal computed tomography(CT) scan is recommended for early revealing direct and indirect signs. We propose three diagnostic points of primary intraperitoneal hernia: 1. "Three-no" pathography: with no history of abdominal operation, abdominal trauma and abdominal infection. 2. It begins with mechanical intestinal obstruction, then turns into strangulated intestinal obstruction easily. 3. Exclude intestinal wall lesions and intestinal blockage. We also summarize surgical procedure into four steps. We hope this case can provide a reference for the diagnosis and treatment of similar situations.

Our hypothesis was that a low concentration (30%) of phenol would be more effective than a high concentration (80%) in the treatment of pilonidal disease. The purpose of our study was to compare the effects of high and low doses of liquid phenol in the treatment of pilonidal disease.

The objective of this study was to present our experience with intrahepatic biliary cystadenomas and cystadenocarcinomas in 10 patients surgically managed in our department. Intrahepatic biliary cystadenomas and cystadenocarcinomas are rare cystic tumors that are often misdiagnosed preoperatively as simple cysts or hydatid cysts. They recur after incomplete resection and entail a risk of malignant transformation to cystadenocarcinoma. A retrospective review was conducted of patients with histologically confirmed intrahepatic biliary cystadenomas and cystadenocarcinomas between August 2004 and February 2013 who were surgically managed in our department. A total of 10 patients, 9 female and 1 male (mean age, 50 years), with cystic liver were reviewed. The size of the cysts ranged between 3.5 and 16 cm (mean, 10.6). Five patients had undergone previous interventions elsewhere and presented with recurrences. Liver resections included 6 hepatectomies, 2 bisegmentectomies, 1 extended right hepatectomy, and 1 enucleation due to the central position and the large size of the lesion. Pathology reports confirmed R0 resections in all cases. All patients were alive after a median follow-up of 6 years (range, 1-10 years), and no recurrence was detected. Intrahepatic biliary cystadenoma and cystadenocarcinoma should be considered in differential diagnosis in patients with liver cystic tumors. Because of the high recurrence rate and difficult accurate preoperative diagnosis, formal liver resection is mandatory. Enucleation with free margins is an option and is indicated where resection is impossible.

This paper is designed to report the endoscopic treatment for a rare esophagopleural fistula after total gastrectomy. Esophagopleural fistula is a rare complication following total gastrectomy. Nonoperative treatment using endoscopic injection of tissue glue is a less invasive and effective option. The history, treatment, and options for managing an esophagopleural fistula following gastrectomy are discussed. A 53-year-old female patient underwent total gastrectomy for advanced gastric cancer. An anastomotic leak with esophagopleural fistula formation developed at the esophagojejunostomy site. The fistula was successfully managed by endoscopic injection with n-butyl-2-cyanoacrylate into the fistula, chest tube drainage, systemic antibiotics, and total parenteral nutrition. This case report suggests that combing effective drainage and the use of n-butyl-2-cyanoacrylate of nonoperative treatment options for esophagopleural fistula.

The objective of this paper was to investigate the association of the serum level of heme oxygenase-1 in patients with intracerebral hemorrhage (ICH) with the risk of ICH. Heme oxygenase-1(HO-1) metabolizes heme into biliverdin, bilirubin, carbon monoxide, and iron, our recent study showed that serum level of HO-1 was increased in stroke patients, yet the association of HO-1 level with risk of intracerebral hemorrhage (ICH) is poorly known. Forty patients with ICH and another 40 patients without ICH were recruited. The serum level of HO-1, total, and direct bilirubin were measured. The level of HO-1, serum total bilirubin, and direct bilirubin, as well as blood pressure were increased in ICH group than in control group (P < 0.001). The level of HO-1, both systolic and diastolic blood pressure had a significant difference between subgroups (P < 0.05). Multivariate regression analysis showed that poor compliance to medicine for hypertension, the serum level of HO-1, and systolic blood pressure were associated with the prevalence of ICH. Blood pressure, serum HO-1, serum total bilirubin, and direct bilirubin were raised in patients with ICH who did not take medicine for hypertension compared with those who did, and increased in ICH patients in comparison with control group. Further investigation in multiple medical centers with large number of cohorts is warranted to verify these results.

In living-donor liver transplantation, graft selection is especially important for the safety of the live donor and an acceptable outcome for the recipient. The essential medical requirements for living liver donation at Jikei University Hospital are as follows: an adult aged 65 years or younger, in good general condition, with partial liver volume of more than 35% of the standard liver volume (SLV) for the recipient, and without severe liver steatosis. Based on our criteria, we performed 13 living-donor liver transplantations between 2007 and 2013, including 1 retransplantation. Three cases were outside our standard donor criteria, including age (18 and 66 years) and 33% graft volume (GV) to SLV ratio for the recipient on preoperative volumetry using computed tomography. In 2 cases, the actual GV to SLV ratio at transplantation was less than 35%. Median postoperative hospital stay was 11 days for the donors, and 29 days for the recipients. All donors returned to their preoperative status, and all recipients were discharged in good condition. Our medical requirements for living liver donation seem to be acceptable because of the good outcome.

The objective of this paper is to apply the transurethral endoscopic technique with the ureteroscope for diagnosis and treatment of the seminal vesicle and ejaculatory duct disorders. At present there is no special equipment designed to enter directly into the seminal vesicle cavity under direct vision. Sixty patients with disorders of the seminal vesicle were included in this study. A 6.5 F rigid ureteroscope (Richard Wolf GmbH, Knittlingen, Germany) was inserted into the posterior urethra to find the verumontanum. Then a 3F catheter (Shanghai Kangge JJMC, Shanghai, China) was inserted into the verumontanum. After that the 6.5 F ureteroscope was introduced into the ejaculatory duct and seminal vesicle to examine them under direct observation. A total of 55 patients were diagnosed and cured successfully with the ureteroscope; 42 (76.4%) patients were discovered to have hemospermia. They were given an anti-inflammatory and seminal vesicle washing. Eight (14.5%) patients who had small stones in the seminal vesicle were offered the operation of the stones removal. Five (9.1%) patients were found to have seminal vesicle gland cysts. The orifices of ejaculatory duct were not found in 3 patients among 5 who were operated unsuccessfully. The ureteroscope failed to enter the seminal vesicle in 2 patients. Some diseases of the seminal vesicle and ejaculatory duct can be easily diagnosed and treated in the clinical practice using a ureteroscope. Transurethral endoscopy technique with the ureteroscope for diagnosis and therapy of the seminal vesicle and ejaculatory duct disorders is safe and practicable.

Mouse unilateral ureteral occlusion (UUO) is widely used as a model of renal experimental obstructive nephropathy with interstitial fibrosis. Microcomputed tomography (micro-CT) imaging has the potential to produce quantitative images. The aim of this study was to establish standard images of micro-CT for renal anatomic and functional evaluations in a mouse model of UUO. UUO was induced in adult male mice BALB/c. In total, 27 mice were used in this study. Three mice per group (a total of 6 groups) were examined with contrast-enhanced micro-CT prior to UUO (day 0) and on days 1, 3, 5, 7, 10, and 14 after UUO. In order to determine the histopathologic correlations at each point in time, contrast-enhanced micro-CT imaging was performed in the 18 remaining mice. All animals were sacrificed, and both kidneys were harvested after the final micro-CT examination. UUO resulted in hydronephrosis and changes in the renal parenchyma. The predominant alteration was substantial changes in the hemodynamics of the renal vascular system after ureteral obstruction for 24 hours or longer, which may be resulting from increased action of vasoconstrictors versus vasodilators. The renal parenchyma was significantly reduced after 1 week, and the features of the histologic changes supported the findings of the micro-CT images. In the contralateral unobstructed kidneys, the images showed a normal structure and function and the pathohistology revealed a normal histoarchitecture. Micro-CT is a useful tool for providing noninvasive monitoring and evaluating the renal structure and function.

Splenic artery aneurysms (SAAs) are the third most frequent intra-abdominal aneurysm, following abdominal aorta and iliac artery aneurysms. SAAs are classified according to their involvement of arterial wall layers: true aneurysms involve all 3 layers (intima, media, and adventitia), and pseudoaneurysms involve only one or two. Herein we present a new case of giant pseudo SAA. A 65-year-old female patient with a pancreatic mass and iron deficiency was referred to our clinic for further investigation. Abdominal ultrasonography, contrast-enhanced CT and magnetic resonance imaging showed a lesion resembling a subcapsular hemangioma in the spleen, and aneurysmatic dilation of the splenic artery with a diameter of >5 cm. The large size of the aneurysm and the clinical findings were indications for surgical treatment. The patient underwent en bloc resection of the spleen, distal pancreas, and aneurysmatic segment of the splenic artery. The patient remains complication-free 2 months after the operation. Spontaneous rupture is the most important life-threatening complications of giant SAAs. Therefore, all symptomatic patients with SAA should be treated, as well as asymptomatic patients with lesions ≥2 cm, who are pregnant or fertile, have portal hypertension, or are candidates for liver transplantation. Despite advances in endovascular techniques, conventional abdominal surgery remains the gold standard for treatment.

Patent vascular access is critical for patients on regular hemodialysis. Prosthetic grafts are good alternatives when the superficial venous system is of poor quality. However, thrombosis is one of the main drawbacks of synthetic grafts, with reports of 59% to 90% patency rates for 1 year. In cases of thrombotic occlusion of prosthetic arteriovenous fistula grafts, percutaneous mechanical thrombectomy has recently gained clinical popularity as a potential alternative to surgical thrombectomy or pharmacologic thrombolysis. We reviewed our preliminary results from 30 percutaneous rotational thrombectomies performed in a total of 22 patients in the setting of acute dialysis-access prosthetic graft occlusion of the upper extremity. Among the 30 cases of acute occlusion of the arteriovenous graft, immediate success with angiographic flow restoration was observed in all patients except for 2 patients (both females; 6%), with de novo occlusion where reocclusion occurred within 12 hours despite apparent immediate angiographic patency. The mean duration between the initial presentation with acute arteriovenous graft occlusion and the thrombectomy procedure was 27.4 ± 12.4 hours. The mean duration of graft patency was 10.45 ± 0.6 months. A total of 75% of the arteriovenous grafts were patent at the end of 12 months of follow-up. Female gender, diabetes mellitus, and diagnosis to intervention interval were reviewed for midterm graft failure, and the presence of diabetes mellitus yielded significance (P < 0.05). Percutaneous techniques play important roles in the treatment of failed or failing arteriovenous fistulae and grafts. Ongoing analysis of outcomes of both percutaneous and surgical intervention is necessary to continue to identify optimum treatment algorithms.
