Endovascular aneurysm repair (EVAR) of combined abdominal and iliac aneurysm requires exclusion of the hypogastric artery for prevention of endoleak. However, exclusion of the hypogastric artery is often associated with significant ischemic complications such as hip or buttock claudication, gluteal necrosis and bowel ischemia. Several techniques have been introduced to preserve the flow of the hypogastric artery. We report a successful case of external iliac artery-to-hypogastric artery bypass with artificial graft combined with EVAR.

Purpose: The purpose of this study was to evaluate the validity and reliability of the Korean version of the Apathy Evaluation Scale Short Form (K AES-10) for people with dementia. Methods: Participants in this study were 198 patients with dementia resident in two hospitals in the Republic of Korea. The AES-10 was translated into Korean through the translation and adaptation of instruments process developed by the World Health Organization. This process was carried out by three bilingual nursing professionals. Validity and reliability, such as construct validity, convergent validity, Cronbach's ⍺, inter-rater reliability, and test-retest reliability, were evaluated. IBM SPSS Statistics 25.0 and AMOS 26.0 programs were used for the data analysis. Results: A uni-dimensional model was proposed in the explanatory factor analysis; a single factor accounted for 68.0% of total variances. The confirmatory factor analysis supported the validity of the Korean version of the AES-10. The scale had a Cronbach's ⍺ of .95, inter-rater reliability of .66 (p<.001), and a test-retest reliability of .81 (p<.001). Conclusion The findings show that the Korean version of the AES-10 is both valid and reliable for measuring apathy among people diagnosed with dementia in the Republic of Korea.

The nutritional support of acutely ill patients is very important and early enteral nutrition is recommended. Feeding via the nasogastric route is used widely for its ease of access if the patient cannot maintain volitional food intake. If the position of the tip or side holes of the nasogastric tube (NGT) is above the gastroesophageal junction, there is the possibility of retention and solidification of the administered enteral feeding formula in the esophagus. Therefore, the tip of the NGT should be checked carefully; a chest radiograph to confirm its position can be considered, especially in patients with a higher risk of aspiration and gastroesophageal reflux. In addition, careful consideration of the risk factors that can trigger esophageal obstruction is required when feeding patients in the intensive care unit. This paper describes two unusual cases of esophageal obstruction caused by the solidification of residue of an enteral feeding formula.

Purpose: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has emerged as a salvage technique changing the paradigm in the management of noncompressible torso hemorrhage. However, training for the REBOA procedure is rarely performed. The endovascular training for REBOA (ET-REBOA) course was conducted to develop the endovascular skills of participants. Methods: Sixteen residents and 12 specialists participated in this educational course. All participants were provided with precourse learning materials. The ET-REBOA course consisted of 2 sections; an ultrasound-guided sheath insertion on the puncture model, and a balloon manipulation on the vascular circuit model. A 13-item procedure checklist and the time required to perform the procedure were examined. Pre/post self-reported confidence score and course satisfaction questionnaire were obtained. Results: Twenty-eight participants performed the 56 REBOA procedures. On the first attempt, the median total time for REBOA from ultrasound-guided vascular access to balloon inflation was 1,139 ± 250 seconds in the resident group and 828 ± 280 seconds in the specialist group. The median shortened time for completion was 273 seconds and 290 seconds respectively. A significant decrease in procedure task time was observed between first and second attempts in the resident group (P = 0.016), specialist group (P = 0.004), and in total among all participants (P < 0.001). Conclusion The ET-REBOA course significantly decreased the time taken to perform the REBOA procedure with high satisfaction of the participants. The course could be an effective curriculum for the development of endovascular skills for performing REBOA.

PURPOSE: Postoperative pancreatic fistula (POPF) is one of the most common and clinically relevant complications after distal pancreatectomy. Some aspects of POPF management remain controversial. Therefore, the aim of this study was to determine the natural course of POPF and fluid collection after distal pancreatectomy and to reappraise the necessity of intraoperative abdominal drainage insertion. METHODS: For recent 10 years, 264 distal pancreatectomies were performed at Seoul National University Hospital. Clinicopathologic data including POPF and postoperative fluid collection (POFC), and its treatment modality were reviewed retrospectively. During follow-up, the location, size, and clinical impact of the POFC were determined on the basis of CT images. RESULTS: Clinically relevant POPFs were identified in 72 patients (27.3%). Therapeutic interventions were performed in 40 patients (55.6%), and conservative management was successful in 32 patients (44.4%). POFC was detected in 191 cases (72.3%) on the first postoperative CT. During follow-up, spontaneous regressions were observed in 119 cases (93.0%). Only thick pancreatic stump increased the risk of clinically relevant POPF (≥17.3 mm, P = 0.002) and the occurrence of POFC (≥16.0 mm, P < 0.001) in multivariate analysis. CONCLUSION: Intraoperative abdominal drainage insertion could be selectively indwelled in patients with a thickness of pancreas ≥17.3 mm. Since radiologically-proven POFC after distal pancreatecomy showed a 93.0 rate of spontaneous regression, POFC without signs of infection can be safely monitored.

BACKGROUND/AIMS: Extended cholecystectomy is generally recommended for patients with T2 gallbladder cancer. However, few studies have assessed the extent of resection relative to T2 gallbladder tumor location. This study analyzed the effects of surgical methods and tumor location on survival outcomes and tumor recurrence in patients with T2 gallbladder cancer. METHODS: Clinicopathological characteristics, extent of resection, survival rates, and recurrence patterns were retrospectively analyzed in 88 patients with pathologically confirmed T2 gallbladder cancer. RESULTS: The 5-year disease-free survival rate was 65.0%. Multivariate analysis showed that lymph node metastasis was the only independent risk factor for poor 5-year disease-free survival rate. Survival outcomes were not associated with tumor location. Survival tended to be better in patients who underwent extended cholecystectomy than in those who underwent simple cholecystectomy. Recurrence rate was not affected by surgical method or tumor location. Systemic recurrence was more frequent than local recurrence without distant recurrence. Gallbladder bed recurrence and liver recurrence were relatively rare, occurring only in patients with liver side tumors. CONCLUSIONS: Extended cholecystectomy is the most appropriate treatment for T2 gallbladder cancer. However, simple cholecystectomy with regional lymph node dissection may be appropriate for patients with serosal side tumors.

BACKGROUNDS/AIMS: Little is known about clinical features and survival outcome in locally advanced unresectable extrahepatic cholangiocarcinoma (EHC). The aim was to investigate the clinical features and the survival outcome in these patients, and to evaluate the role of palliative resections in locally advanced unresectable EHC. METHODS: Between 1995 and 2007, 280 patients with locally advanced unresectable EHC were identified. Clinical, pathologic, and survival data were investigated. A comparative analysis was done between those who received palliative resection (PR) and those who were not operated on (NR). RESULTS: The overall median survival of the study population was 10+/-1 months, and the 3- and 5-year survival rates (YSR) were 8.5% and 2.5%, respectively. The median survival, 3- and 5-YSR of PR were 23 months, 32.1% and 13.1%, respectively. For NR, they were 9 months, 3.9% and 0%, which were significantly worse than PR (p<0.001). In univariate analysis, T classification, N classification, tumor location, palliative resection, adjuvant treatment, chemotherapy, and radiation therapy were factors that showed survival difference between PR and NR. Regional lymph node metastasis (RR, 2.084; 95% CI, 1.491-2.914; p<0.001), non-resections (RR, 2.270; 95% CI, 1.497-3.443; p<0.001), and no chemotherapy (RR, 1.604; 95% CI, 1.095-2.349; p=0.015) were identified as risk factors for poor outcome on multivariate analysis. CONCLUSIONS: Without evidence of systemic disease, palliative resection may provide some survival benefit in selected locally advanced unresectable EHCs and adjuvant treatment may further improve survival outcome.

Pseudohypoparathyroidism type Ia (PHP Ia) is a disorder characterized by multiform hormonal resistance including parathyroid hormone (PTH) resistance and Albright hereditary osteodystrophy (AHO). It is caused by heterozygous inactivating mutations within the Gs alpha-encoding GNAS exons. A 9-year-old boy presented with clinical and laboratory abnormalities including hypocalcemia, hyperphosphatemia, PTH resistance, multihormone resistance and AHO (round face, short stature, obesity, brachydactyly and osteoma cutis) which were typical of PHP Ia. He had a history of repeated convulsive episodes that started from the age of 2 months. A cranial computed tomography scan showed bilateral calcifications in the basal ganglia and his intelligence quotient testing indicated mild mental retardation. Family history revealed that the patient's maternal relatives, including his grandmother and 2 of his mother's siblings, had features suggestive of AHO. Sequencing of the GNAS gene of the patient identified a heterozygous nonsense mutation within exon 11 (c.637 C>T). The C>T transversion results in an amino acid substitution from Gln to stop codon at codon 213 (p.Gln213*). To our knowledge, this is a novel mutation in GNAS.

BACKGROUND AND OBJECTIVES: Cardiac resynchronization therapy (CRT) has been known to improve the outcome of advanced heart failure (HF) but is still underutilized in clinical practice. We investigated the prognosis of patients with advanced HF who were suitable for CRT but were treated with conventional strategies. We also developed a risk model to predict mortality to improve the facilitation of CRT. SUBJECTS AND METHODS: Patients with symptomatic HF with left ventricular ejection fraction < or =35% and QRS interval >120 ms were consecutively enrolled at cardiovascular hospital. After excluding those patients who had received device therapy, 239 patients (160 males, mean 67+/-11 years) were eventually recruited. RESULTS: During a follow-up of 308+/-236 days, 56 (23%) patients died. Prior stroke, heart rate >90 bpm, serum Na < or =135 mEq/L, and serum creatinine > or =1.5 mg/dL were identified as independent factors using Cox proportional hazards regression. Based on the risk model, points were assigned to each of the risk factors proportional to the regression coefficient, and patients were stratified into three risk groups: low- (0), intermediate-(1-5), and high-risk (>5 points). The 2-year mortality rates of each risk group were 5, 31, and 64 percent, respectively. The C statistic of the risk model was 0.78, and the model was validated in a cohort from a different institution where the C statistic was 0.80. CONCLUSION: The mortality of patients with advanced HF who were managed conventionally was effectively stratified using a risk model. It may be useful for clinicians to be more proactive about adopting CRT to improve patient prognosis.

PURPOSE: Free tumor cells in peritoneal fluid in patients with pancreatic cancer may have prognostic significance but there are few reports on methods for the effective detection of free tumor cells. The aims of this study were to identify free cancer cells in peritoneal fluid with fluorescent in situ hybridization (FISH) technique and to investigate its prognostic significance. METHODS: Twenty-eight patients with resectable pancreatic cancer who underwent surgical resection were included. Peritoneal washing and peritoneal drainage fluid were examined by FISH for p53 deletion. RESULTS: Among the study subjects, the R0 resection rate was 75%. None of the patients had positive cytology with Papanicolaou's method. p53 deletion was detected in 9 peritoneal washings (32.1%) and in 5 peritoneal drainage fluids (17.9%). After a median of 18 months of follow-up, 25 patients (89.3%) experienced recurrence and 14 patients (50.0%) had peritoneal seeding. Patients with p53 deletion detected in the peritoneal drainage fluid had positive radial margin (60.0% vs. 17.4%, P = 0.046) more frequently and a lower peritoneal metastasis free survival (median, 11.1 months vs. 30.3 months; P = 0.030). Curative resection (P < 0.001) and p53 deletion in peritoneal drainage fluid (P = 0.030) were independent risk factors of peritoneal metastasis free survival after multivariate analysis. CONCLUSION: FISH technique detects free cancer cells with higher sensitivity compared to Papanicolaou's method. p53 deletion detected in peritoneal drainage fluid is correlated with positive radial resection margin and results in early peritoneal seeding. Patients with p53 deletion in peritoneal drainage fluid need more aggressive adjuvant treatment.
