BACKGROUND: Little is known about the preoperative predictive factors that could identify subsets of favorable patients who can be possibly cured with robot-assisted radical prostatectomy (RARP) alone in locally advanced prostate cancer (LAPCa). Our study was designed to identify clinical predictors of pathologic organ-confined disease (pOCD) in RARP setting. METHODS: Between 2007 and 2013, clinicopathological and oncological data from 273 consecutive men undergoing robot-assisted RP with extended PLND for clinically LAPCa were reviewed in a single-institution, retrospectively...

BACKGROUND: Obesity is generally reported to increase the risk of surgical complications. There have been few reports of laparoscopic hepatectomy (LH) in obese patients. The purpose of this study was to compare the safety and efficacy of (1) LH versus open hepatectomy (OH) in obese patients and (2) LH in obese patients versus LH in non-obese patients. METHODS: We introduced LH at our institution in April 2014. LH was performed in 63 obese patients and 108 non-obese patients from April 2014 to May 2017...

BACKGROUND/OBJECTIVE: The purpose of this study is to assess outcomes and the detailed clinicopathological features of differentiated thyroid carcinoma (DTC), including the relation of Hashimoto's thyroiditis and postoperative pathological features in child under 18 years old. METHODS: We reviewed patients with DTC under 18 years old (pediatric DTC patients) seen during recent 16 years. The clinicopathological features and outcomes of pediatric DTC were analyzed by comparison with patients of 19-20 years old or 21-44 years old...

This meta-analysis aimed to explore the effect of infrahepatic vena cava (IVC) clamping on bleeding during hepatic resection. PubMed and Embase databases were searched systematically to identify randomized controlled trials (RCTs) comparing infrahepatic IVC clamping to IVC nonclamping during hepatic resection. A random-effects model was used to calculate weight and outcome measures. Five RCTs involving a total of 596 patients were identified for inclusion: 299 in infrahepatic IVC clamping group and 297 in nonclamping group...

OBJECTIVE: We compared the perioperative outcomes of patients with bladder cancer according to three different procedures: robot-assisted laparoscopic radical cystectomy (RALC), laparoscopic radical cystectomy (LRC), and open radical cystectomy (ORC). METHODS: From April 2008 to March 2017, 36 consecutive patients underwent radical cystectomy and ileal conduit with RALC (n = 10), LRC (n = 10), or ORC (n = 16). All patients underwent RALC and LRC with extracorporeal urinary diversion...

BACKGROUND: Indications and efficacy of surgical treatment for liver metastases from gastric cancer (LMGCs) remain controversial. This retrospective study was designed to clarify the benefits of surgical treatment and identify prognostic factors. METHODS: Between December 1997 and December 2015, 34 consecutive patients underwent hepatic resection and surgical microwave ablation for synchronous or metachronous LMGCs at our institution. We analyzed their cumulative overall survival (OS) and recurrence-free survival (RFS) rates and clinical parameters to identify predictors of prognosis...

BACKGROUND/OBJECTIVE: The definition of R0 resection for invasive pancreatic ductal carcinoma (IPDC) is important. However, there are different definitions among several countries in the world. METHODS: From 2001 to 2015, 100 consecutive patients with IPDC who underwent pancreatic resection in our hospital were enrolled. We compared survival and recurrence patterns between the R0 group and R1 group based on the UICC (Union for International Cancer Control) classification (current-R0 vs...

BACKGROUND/OBJECTIVES: The natural history of type II endoleaks (T2ELs) is still not completely understood; however, it is widely accepted that those associated with aneurysmal sac growth are harmful. We aimed to review our experience with T2ELs in endovascular aneurysm repair (EVAR). METHODS: We retrospectively reviewed electronic medical records of all patients who underwent EVAR for infrarenal-type abdominal aortic aneurysms (AAAs) at a single institution from August 2007 to November 2015...

BACKGROUND: Determining the survival outcome for gastric cancer patients with metastases to more than 15 regional lymph nodes is difficult. This study aims to develop a lymph node metastatic ratio (LNR)-based prognostic model to predict the survival outcome after D2 surgery in such patient groups. METHODS: Our study retrospectively enrolled 139 gastric cancer patients with metastases to more than 15 regional lymph nodes who underwent D2 surgery between 2007 and 2014...

BACKGROUND: The study aims to report outcomes of open repair (OR) and endovascular aneurysm repair (EVAR) in octogenarians. METHODS: Consecutive patients aged between 80 and 89 who underwent OR or EVAR were identified from a prospectively collected departmental database. Short-term outcomes included 30 days mortalities and perioperative complications; long-term outcomes included overall survival and re-intervention using the Kaplan-Meier method. Logistic regression was used to identify predictors for operative mortality and Cox regression analysis was used to identify predictors for long-term survival...

BACKGROUND: In patients with acute biliary pancreatitis (ABP), cholecystectomy is mandatory to prevent further biliary events, but the precise timing of cholecystectomy for mild to moderate disease remain a subject of ongoing debate. The aim of this study is to assess the outcomes of early versus delayed cholecystectomy. We hypothesize that early cholecystectomy as compared to delayed cholecystectomy reduces recurrent biliary events without a higher peri-operative complication rate. METHODS: Patients with mild to moderate ABP were prospectively randomized to either an early cholecystectomy versus a delayed cholecystectomy group...

BACKGROUND/OBJECTIVE: To compare the curative effect of single-stage and two-stage Fowler-Stephens (F-S) laparoscopic orchidopexy for intraabdominal high testis and explore the appropriate surgical approach. METHODS: We performed a prospective analysis of the clinical data of 28 patients who underwent F-S laparoscopic orchidopexy for intraabdominal high testis in our department from May 2012 to April 2015, including 15 cases of the single-stage F-S operation and 13 cases of the two-stage F-S operation...

BACKGROUND: Routine therapy of metabolic bone disorder (MBD) after gastrectomy for gastric cancer has not been established yet. We have reported that administering an active vitamin D3 agent to patients who had undergone gastrectomy for gastric cancer improved MBD. Recently, the usefulness of alendronate, an osteoclast inhibitor, has been reported for MBD. Here we report the effects of alendronate for MBD after gastrectomy for gastric cancer. METHODS: Dual energy X-ray absorptiometry was performed consequently in 14 patients, who had been gastrectomized for gastric cancer and survived more than 5 years without recurrence, to evaluate the MBD and compared before and after treatment...

BACKGROUND: This study aims to analyze the contact areas and pressure distributions between the femoral head and mortar during normal walking using a three-dimensional finite element model (3D-FEM). METHODS: Computed tomography (CT) scanning technology and a computer image processing system were used to establish the 3D-FEM. The acetabular mortar model was used to simulate the pressures during 32 consecutive normal walking phases and the contact areas at different phases were calculated...

BACKGROUND: In multilevel arterial disease, whether complete revascularization or staged runoff repair should be performed remains controversial. The aim of this study was to evaluate the efficacy of iliac inflow repair and to identify clinical conditions that are associated with the need for runoff repair in concomitant iliac and superficial femoral artery (SFA) occlusive disease. METHODS: Patients undergoing inflow repair for complicated flow-limiting iliac lesions with diffuse SFA disease between 2007 and 2013 were retrospectively reviewed...

BACKGROUND: Whether hepatic resection (HR) could be performed for patients with Barcelona Clinic Liver Cancer (BCLC) B/C stage hepatocellular carcinoma (HCC) is controversial, and the safety and clinical value of HR combined with antiviral therapy for hepatitis B virus (HBV)-related HCC with BCLC-B/C stage remain to be investigated. METHODS: We retrospectively evaluated 126 patients with BCLC stage B/C HCC who underwent HR. These patients were divided into the antiviral group (Group A, n = 86) and the control group (Group B, n = 40)...
