Abstract
A 38-year-old woman was admitted to our hospital due to severe anemia. CT showed a 13×12 cm tumor with moderately enhanced wall thickening in the right upper abdomen. The huge tumor located adjacent to the jejunum and compressed the right transverse colon. Hemorrhagic necrosis and air were observed within the tumor, suspecting tumor penetration into the jejunum. The patient was diagnosed with abdominal GIST with jejunal infiltration. Laparotomy revealed a 13× 11 cm solid mass with intra-tumoral hemorrhage and invasion into the jejunum, located in the transverse mesocolon. Tumor resection combined with partial jejunectomy and transverse colectomy were performed. Immunohistochemical findings of the resected specimen was positive for c-kit and DOG-1, and the MIB-1 positive rate was 10%. Three weeks after the operation, re-anastomosis was performed due to transverse colon anastomotic stricture. She was discharged 45 days after first operation. Currently, 9 months after the operation, patient has been prescribed imatinib and is alive without recurrence.

An ampullary adenoma presenting with jaundice caused by duodenal intussusception: a case report. Surg Case Rep 2024; 10:25. [PMID: 38252200 PMCID: PMC10803710 DOI: 10.1186/s40792-024-01822-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 01/12/2024] [Indexed: 01/23/2024] Open
Abstract
BACKGROUND Ampullary adenomas are premalignant lesions. However, biliary obstruction causing jaundice is rare. Duodenal intussusception secondary to an ampullary adenoma rarely occurs because of the fixed position of the duodenum in the retroperitoneum. Herein, we have described a rare case of ampullary adenoma with jaundice caused by duodenal intussusception. CASE PRESENTATION A 40-year-old woman presenting with vomiting and yellowish discoloration of the skin was admitted to another hospital. The patient had experienced recurrent epigastric pain and vomiting for the past 18 months. Blood test results showed elevated levels of bilirubin (3.9 mg/dL), and abdominal computed tomography (CT) showed a 60-mm hypovascular mass in the third part of the duodenum and a left lateral shift of the dilated common bile duct. The patient was referred to our hospital for further evaluation. She recovered from hyperbilirubinemia spontaneously (levels of bilirubin, 1.0 mg/dL), and the CT showed a tumor shift from the third part of the duodenum to the second part and improvement of the dilated common bile duct. Hypotonic duodenography revealed a tumor that moved easily from the second to the third portion of the patient's position. Upper gastrointestinal endoscopy revealed a large papillary tumor occupying the second part of the duodenum, which was diagnosed as an adenoma through biopsy. The possibility of malignancy could not be negated owing to the presence of jaundice and an elevated carbohydrate antigen 19-9 level (76.0 U/mL). Pancreaticoduodenectomy was performed. The resected specimen showed a 60 × 40 × 40-mm pedunculated ampullary mass with submucosal elongation. The pathological examination indicated that the ampullary tumor was a high-grade intestinal adenoma. The postoperative course was uneventful, and the patient was discharged 26 days postoperatively. CONCLUSIONS This report describes a rare case of a patient with an ampullary adenoma presenting with jaundice resulting from duodenal intussusception. Owing to the possibility of a postoperative cancer diagnosis which may have caused the biliary obstruction and the difficulty in making an accurate preoperative diagnosis, it is imperative to choose the appropriate surgical procedure such as a pancreaticoduodenectomy.

Abstract
By designing a unimorph suitable for the material properties of (K, Na)NbO3-based lead-free piezoelectric ceramics (KNN), we have developed a piezoelectric sounder with a sound pressure level that is superior to that of similar devices based on Pb(Zr, Ti) [Formula: see text] (PZT) over a wide temperature range. The KNN ceramics used in this work have two disadvantages: their piezoelectric constant, d31 , at room temperature is less than 80% of that of PZT, and their piezoelectric properties deteriorate because of phase transitions to the orthorhombic phase at low temperatures. The former issue was alleviated via design of a thin-layer unimorph that uses the specific mechanical properties of KNN, i.e., a large Young's modulus and low specific gravity when compared with the corresponding properties of PZT; a unimorph was then fabricated with both a vibration velocity and a resonance frequency that are comparable to those of PZT unimorphs. The latter issue was then resolved by reducing the resonance frequency of the unimorph relative to the acoustic resonance frequency of the resonator, which produced a stronger vibration-acoustic coupling effect within the temperature range in which the piezoelectric properties of KNN are lower. The KNN sounder designed in this manner exhibited a sound pressure level that was 1.4 dB greater than that of a PZT sounder at room temperature, and the range of change in the sound pressure level from -20 °C to 90 °C was 2 dB less than that for the PZT sounder.

Successful hepatic resection for invasive Klebsiella pneumoniae large multiloculated liver abscesses with percutaneous drainage failure: A case report. Front Med (Lausanne) 2023; 9:1092879. [PMID: 36687430 PMCID: PMC9852881 DOI: 10.3389/fmed.2022.1092879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Accepted: 12/15/2022] [Indexed: 01/09/2023] Open
Abstract
Background Invasive Klebsiella-associated liver abscesses can progress rapidly and cause severe metastatic infections such as meningitis and hydrocephalus, which are associated with high morbidity and mortality. In patients with large multiloculated liver abscesses after failure of percutaneous drainage, rapid diagnosis of the abscess followed by hepatic resection is necessary for early recovery and to prevent severe secondary metastatic complications. Case presentation An 84-year-old woman with a large liver abscess and in septic shock was transferred to our hospital. Abdominal CT showed multiloculated liver abscesses 15 cm in diameter in the right lobe of the liver. We first performed percutaneous liver abscess drainage. The patient was managed in the intensive care unit, as well as treated with intravenous administration of meropenem followed by cefozopran according to the antibiogram. Klebsiella pneumoniae with invasive infection was confirmed by a string test in an isolated colony of K. pneumoniae; the K1 serotype with the rmpA and magA genes was determined by polymerase chain reaction and Sanger sequencing. Additional percutaneous liver abscess drainage was performed due to initial inadequate drainage. Although the abscess had shrunk to a diameter of 8 cm after drainage in 4 weeks, the patient recovered from sepsis, but still had low-grade fever (occasionally 38°C) and continued to have symptoms of chronic inflammation with persistent hyper mucus discharge from the liver abscess. Surgical resection was chosen to prevent prolonged hospitalization and ensure early recovery. A right posterior sectionectomy of the liver, including liver abscess, was performed. The post-operative course was uneventful, with no complications, and she was discharged after 18 days. There were no signs of abscess recurrence 1 year after surgery. Conclusion We present a case of successful hepatic resection after percutaneous drainage failure in a patient with invasive K. pneumoniae multiloculated liver abscess.

Abstract
An 83-year-old woman developed jaundice, and was diagnosed as perihilar cholangiocarcinoma. Abdominal contrast- enhanced CT revealed coexisting portosystemic shunt between portal vein and inferior vena cava, however, her blood ammonia level was normal. She underwent right hemihepatectomy and caudate lobectomy combined with extrahepatic bile duct resection and portal vein resection. Postoperatively, hyperammonemia refractory to conservative treatment was observed. The blood ammonia level increased to 180μg/dL and she was suffered from grade Ⅲ hepatic encephalopathy on the 20th postoperative day. CT showed an increase in the diameter of the portosystemic shunt, while there was only a slight increase in the remnant left lobe of the liver. These findings indicated that hepatic encephalopathy was caused by increased portosystemic shunt blood flow and decreased portal venous flow. Hepatic encephalopathy was rapidly improved by percutaneous transhepatic portosystemic shunt obliteration.

Abstract
An 81-year-old woman was admitted to our hospital due to frequent bleeding and hemorrhagic shock. Blood tests revealed anemia and contrast-enhanced abdominal CT revealed a pancreatic tail tumor with a diameter of 60 mm. The boundary between pancreatic tumor and the transverse colon, stomach and spleen was unclear, and invasion of the transverse colon as well as the stomach and spleen was suspected. Hemorrhage due to colon invasion of the pancreatic tail cancer and intra-tumoral hemorrhage were suspected. Due to persistent bleeding, the patient had emergency surgery to control bleeding. The pancreatic tail tumor invaded not only the colon but also stomach and spleen, distal pancreatectomy, partial gastrectomy and splenectomy was performed in combination with resection of the transverse colon, and transverse colon colostomy. We report a case of gastrointestinal bleeding caused by transverse colon invasion of pancreatic tail cancer, which resulted in emergency surgery.

Intra-abdominal ectopic bronchogenic cyst with a mucinous neoplasm harboring a GNAS mutation: A case report. World J Clin Cases 2022; 10:8709-8717.

Abstract
BACKGROUND Bronchogenic cysts are congenital cysts caused by abnormal sprouting from the ventral foregut during fetal life. They usually occur in the mediastinum or lung, but there are very rare cases of ectopic bronchogenic cysts that develop in the abdominal cavity. A unique intra-abdominal ectopic bronchogenic cyst with a mucinous neoplasm that was producing carcinoembryonic antigen (CEA), harboring a GNAS mutation, is reported. The present case may contribute to clarifying the mechanism of tumorigenesis and malignant transformation of ectopic bronchogenic cysts.
CASE SUMMARY In 2007, a man in his 50s was incidentally found to have an intra-abdominal cystic mass, 8 cm in diameter. Surgical resection was recommended, but he preferred to remain under observation. In 2020, his serum CEA level increased to 26.7 ng/mL, and abdominal computed tomography showed a 15 cm × 12 cm, multifocal, cystic mass located predominantly on the lesser curvature of the stomach. Since malignancy could not be ruled out, he finally underwent surgical resection. Histologically, the cystic wall was lined by ciliated columnar epithelium, accompanied by bronchial gland-like tissue, bronchial cartilage, and smooth muscle. Part of the cyst consisted of atypical columnar epithelium with an MIB-1 index of 5% and positive for CEA. Moreover, a GNAS mutation (p.R201C) was detected in the atypical epithelium, leading to a diagnosis of an ectopic bronchogenic cyst with a low-grade mucinous neoplasm. The patient is currently undergoing outpatient follow-up without recurrence.
CONCLUSION An extremely rare case of an abdominal bronchogenic cyst with a low-grade mucinous neoplasm harboring a GNAS mutation was reported.

Abstract
BACKGROUND Several studies have demonstrated that diverse systemic inflammatory-based prognostic parameters predict a poor prognosis in patients with gastric cancer. However, few studies have focused on the relationships between postoperative complications and systemic inflammatory-based prognostic parameters after curative gastrectomy. We investigated the relationships between postoperative complications and these parameters and assessed the clinical utility of the parameters as predictors of postoperative complications in patients with stage I-III gastric cancer. METHODS We retrospectively reviewed 300 patients who underwent curative gastrectomy for stage I-III gastric cancer. All postoperative complications were classified as infectious or noninfectious. We evaluated the relationships between postoperative complications and clinical factors, including systemic inflammatory-based prognostic parameters. RESULTS In total, 101 patients (33.7%) had postoperative Clavien-Dindo grade II-IV complications, and 54 (18.0%) patients developed infectious complications including pancreatic fistula, pneumonia, anastomotic leak, intra-abdominal abscess, and cholecystitis. The relationships between postoperative complications and systemic inflammatory-based prognostic parameters were evaluated by the areas under the receiver operating characteristic curves. Postoperative pneumonia was identified as the most sensitive complication to the systemic inflammatory-based prognostic parameters. Multivariate analysis revealed that preoperative neutrophil-to-lymphocyte ratio (odds ratio, 14.621; 95% confidence interval, 1.160-184.348; p = 0.038) was an independent predictor of pneumonia. CONCLUSIONS Preoperative neutrophil-to-lymphocyte ratio may be a useful predictor of postoperative pneumonia in patients with stage I-III gastric cancer after curative gastrectomy.

Abstract
BACKGROUND Anastomotic leak is one of the most serious postoperative complications, and intraoperative adequate perfusion plays a key role in preventing its development in gastric cancer surgery. This study aimed to investigate the relationships between anastomotic leak and the parameters defined by an assessment of intraoperative anastomotic perfusion using a near-infrared indocyanine green (ICG) fluorescence system and to evaluate the usefulness of this ICG fluorescence assessment in gastric cancer surgery. METHODS We retrospectively reviewed data of 100 patients who underwent gastric cancer surgery. In a visual assessment based on fluorescence intensity, we classified ICG fluorescence image patterns as homogeneous, heterogeneous, or faint. In a chronological assessment, the first or second time point of ICG fluorescence appearance on one or the other side of the anastomosis was defined as FT or ST, respectively. The time difference in ICG fluorescence appearance between FT and ST was defined as TD. The relationships between anastomotic leak and the evaluated clinical factors, including the parameters identified by the ICG fluorescence assessment, were evaluated using univariate or multivariate analysis. RESULTS Although no signs of leak were found by surgeons' subjective judgments, four patients developed postoperative anastomotic leak of Clavien-Dindo grade III or IV. Multivariate analysis revealed that TD was an independent predictor of anastomotic leak (odds ratio 35.361, 95% confidence interval 1.489-839.923, p = 0.027). CONCLUSIONS A novel parameter identified using near-infrared ICG fluorescence assessment may be useful to predict anastomotic leak in gastric cancer surgery.

Abstract
Abstract
Background
Recent development of electrophysiology-guided noninvasive cardiac radioablation therapy for ventricular tachycardia attracts a great deal of attention as a novel antiarrhythmic strategy (Robinson CG, Circulation 2019). As to underlying mechanisms, however, much remains to be clarified. We reported before that a single targeted heavy ion irradiation (THIR 15Gy) to rabbit hearts increased connexin43 (Cx43) expression, and a reduction of vulnerability to ventricular arrhythmias after myocardial infarction.
Purpose
We investigated the effects of THIR on in-vivo cardiac electrophysiology and vulnerability to atrial and ventricular tachyarrhythmias in aged rabbits with hypercholesterolemia.
Methods
Sixteen three-year old rabbits were fed with high fat/cholesterol chow (0.5% cholesterol and 10% coconut oil) for 14 weeks. A single THIR 15Gy was applied to 8 rabbits (HC+THIR) with a heavy ion medical accelerator. Eight rabbits without THIR were used as control (HC).
Results
Serum cholesterol levels in the HC and HC+THIR were 1545+386 and 1569+328 mg/dl (n=8, NS). Atrial (P-wave) late potential in signal-averaged ECG in HC+THIR showed a significantly larger root mean square voltage (RMS) than those in HC (12+0.5 vs. 2+0.5μV, n=4, p<0.01). Ventricular late potentials in HC+THIR showed significantly less fQRS-D than HC (81+5 vs. 89+7 ms); less LAS40 (21+7 vs. 30+4 ms), and larger RMS (99+27 vs. 44+13μV) (n=4, p<0.04). Atrial tachycardia or fibrillation (AT/AF) was induced spontaneously or by programmed/burst pacing of the left atria (LA) in 4 out of 4 HC, whereas in only 1 out of 4 HC+THIR. Ventricular tachycardia or fibrillation (VT/VF) was induced spontaneously or by programmed pacing or left stellate stimulation in 4 out of 4 HC rabbits, whereas in only 1 out of 4 HC+THIR. Immunolabeled Cx40 densities in LA and RA tissue from HC+THIR rabbits were significantly higher than those from HC rabbits by 44% and 60%, respectively (n=4, p<0.01). Comparable upregulation of immunoreactive Cx43 was observed in LV and RV tissue from HC+THIR rabbits. Sympathetic nerve densities in LA, RA, LV and RV tissues, which was labeled with anti-neuronal growth-associated protein 43 (GAP43) antibody and tyrosine hydroxylase (TH) antibody were both significantly less in HC+THIR than those in HC.
Conclusion
These results suggest that THIR may improve cardiac conductivity of HC rabbits in favor of reduction of vulnerability to atrial and ventricular tachycardia/fibrillation, and that this antiarrhythmic effect is attributed to upregulation of gap junction protein (Cx40 and Cx43) and in part to prevention of sympathetic nerve sprouting.

Abstract
Background
It is known that low diastolic blood pressure (DBP) is associated with long-term cardiovascular events after acute myocardial infarction (AMI). However, the impact of low diastolic blood pressure on short-term outcome has not yet been well investigated.
Methods and results
We included 15,208 patients who were hospitalized for AMI and registered in the Tokyo CCU network registry between 2013 and 2016. Thirty-day in-hospital mortality rate was 4.8% (728/15,208). To assess the relationship between DBP at the time of admission and 30-day mortality non-linearly, spline regression model was applied with the stratification of the cohort according to tercile of systolic blood pressure (SBP, low:≤122 mmHg, intermediate:123–148 mmHg, high:≥149 mmHg) and J-curve phenomenon was observed in the low and high SBP groups. In multivariate logistic regression analysis, adjusted odds ratio of the lowest quintile of DBP (≤64 mmHg) was 1.65 (95% CI:1.02–2.66) in low SBP group and 4.55 (95% CI:1.72–12.00) in high SBP group.
Conclusion
Low DBP was associated with increased 30-day in-hospital mortality rate after AMI even in patients with high SBP.

Abstract
Ectomesenchymal chondromyxoid tumour (ECT) is an extremely rare intraoral mesenchymal tumour. Most of these tumours have been identified on the anterior aspect of the dorsal surface of the tongue. ECT is difficult to diagnose because of its rarity. We report a case of ECT arising on the lateral border of the tongue in a 67-year-old woman. The tumour, measuring 20 × 10 mm in size, was surgically removed. Histopathologically, the tumour was composed of small polygonal cells arranged in sheets, with a myxoid or hyalinized stroma. The tumour boundary was clear; however, the tumour showed a multinodular structure expanding along the tongue surface without obvious capsule. Careful examination revealed the tumour nodule to be spreading in a skip lesion-like fashion away from the main part of the tumour in the striated muscle layer. Although there was no evidence of recurrence at 18 months after the surgery, our observations suggest that surgery for ECT resection with a safety margin is more appropriate than enucleation.

Abstract
The objectives of this study were to evaluate survival in 141 patients with stage II-IV oral squamous cell carcinoma (OSCC) treated with preoperative intra-arterial chemotherapy with docetaxel, cisplatin, and peplomycin combined with intravenous chemotherapy using 5-fluorouracil (IADCPIVF) via the superficial temporal artery, and to clarify the prognostic factors. The study population included 59 patients with stage II OSCC, 34 with stage III, and 48 with stage IV. After IADCPIVF, 139 patients underwent surgery; minimally invasive surgeries (MIS) including excisional biopsy were performed on 96 patients with a remarkably good response to IADCPIVF. The primary tumour response rate was 99.3% (complete response rate 56.7%, good partial response rate 17.0%, fair partial response rate 25.5%). Additionally, there were no serious adverse events associated with IADCPIVF. The 5-year overall survival rate was 74.6% (stage II 83.6%, stage III 72.7%, stage IV 64.8%). In the multivariate analysis of survival, T classification and clinical tumour response were significant prognostic factors. Eight (8.3%) of the patients who received MIS had primary recurrence and six were salvaged. In conclusion, IADCPIVF is safe and efficacious for treating OSCC, and MIS could reduce the extent of primary tumour resection in the case of a remarkably good response.

Abstract
BACKGROUND Laparoscopic transverse colectomy is technically difficult. In mini-laparotomy surgery, colectomy for midtransverse colon cancer can easily be performed, but exact D2 lymph node dissection is very difficult for a variety of vessels in the transverse colon. Using 3D-CT imaging, we present a case of D2 lymph node dissection where mini-laparotomy transverse colectomy was performedby a small incision similar to that usedin laparoscopic surgery. METHOD The patient was a 60-yearoldwoman with early transverse colon cancer, which was locatedin the mid-transverse colon. Surgical treatment was plannedfor pT1b(1.5mm)andpVM1 in pathological findings after EMR. Using CT colonography(CTC), the location of the primary tumor was identified. Using simulation CTC(sCTC), composedof CTC and 3D imaging of the arteries andveins, the dominant artery was identified and D2 lymph node dissection was simulated. In addition, body surface 3D imaging and permeable surface 3D imaging of the abdominal trunk were performed. Using body surface 3D-sCTC, composedof sCTC and body surface 3D imaging, the minimum incision to enable D2 lymph node dissection was simulated. RESULT Using sCTC, it was identified that the dominant artery was the right branch of the middle colic artery(MCA Rt)andthe accompanying vein was branchedfrom the gastrocolic trunk(GCT). D2 lymph node dissection to separate the branching root of MCA Rt and the accompanying vein was simulated. Next, surgical incision was simulated using body surface 3D-sCTC. Because the branching roots of MCA Rt andGCT were locatedabout 5 cm cranial from the upper rim of the navel, a 7 cm upper abdominal midline incision was designed in addition to a 2 cm umbilical incision. Mini-laparotomy transverse colectomy with a 7 cm incision was performedin accordance with the simulation. The operation time was 2 hours and5 1 minutes, andbloodloss was due to occult bleeding. The patient was discharged 7 days after surgery without complications, and the final diagnosis was pT1bN0M0, StageⅠwith no recurrence for 4 years and2 months after surgery. The cranial incision from the upper rim of the navel has shrank about 3 cm, and the umbilical incision is not noticeable. CONCLUSION D2 lymph node dissection of minilaparotomy transverse colectomy can be a treatment option for early transverse colon cancer through using body surface 3DsCTC.

Abstract
Abstract
Background
Although the patient's characteristics and outcome of acute myocardial infarction (AMI) have been sufficiently investigated and primary percutaneous coronary intervention (PCI) has been recognized as established treatment strategy, those of recent myocardial infarction (RMI) have not been fully evaluated.
Purpose
The purpose of the present study was to clarify clinical characteristics and in-hospital outcomes of RMI patients from the database of the Tokyo CCU network multicenter registry.
Methods
In Tokyo CCU network multicenter registry database from 2013 to 2016, 15788 consecutive patients were registered as AMI (within 24 hours from onset) and RMI (within 2–30 days from onset). However 1246 patients were excluded because of inadequate data. And we excluded 66 cases because of out of onset period and 129 cases that strongly suspected of involvement of vasospastic events. Therefore, remaining 14347 patients were categorized to RMI group (n=1853) and AMI group (n=12494), and analyzed.
Results
Compared with AMI group, average age was older (70.4±12.9 vs 68.0±13.4 years, p<0.001), male was less (72.4 vs 76.4%, p<0.001), chest pain as chief complaint was less (75.2 vs 83.6%, p<0.001), prevalence of diabetes mellitus was higher (35.9 vs 31.0%, p<0.001), multi-vessel coronary disease was more (54.7 vs 44.6%, p<0.001), patients undergoing PCI was less (79.0 vs 91.2%, p<0.001), and the incidence of mechanical complication was more in RMI group (3.0 vs 1.5%, p<0.001). Although 30-day mortality was equivalent between 2 groups (5.3 vs 5.8%, p=0.360), the major cause of death in AMI group was cardiogenic shock, while in the RMI group it was a mechanical complication. On Kaplan-Meier analysis, the 2 groups had significantly different cumulative incidence of death due to cardiogenic shock (p=0.006, Log-rank test) and mechanical complication (p=0.021, Log-rank test). Furthermore death due to mechanical complication in AMI group was plateau after about 1 week from hospitalization, whereas in RMI group it continued to increase.
Kaplan-Meier analysis
Conclusions
RMI patients had distinctive clinical features in backgrounds and treatment strategies compared with AMI patients, and the major cause of death of RMI patients was different from that of AMI patients. Furthermore, even though treatment during hospitalization of RMI patients was well done, death due to mechanical complications continued to increase.

Abstract
The aim of this study was to assess the impact of partial gastrectomy on postoperative outcomes in elderly patients with gastric cancer. Sixty -three consecutive elderly patients aged 75 years and older with histologically proven Stage ⅠA gastric adenocarcinoma who underwent partial gastrectomy(PG, n=7)or normal gastrectomy(NG, n=56)were investigated. PG was performed by segmental gastrectomy or local gastrectomy due to poor performance status, severe comorbidities, and social background instead of normal gastrectomy(distal, proximal, and total gastrectomy). Both body mass index(BMI)and body weight changes 12 months postoperatively were significantly higher in those who underwent PG(20.5 kg/m2 vs 18.4 kg/m2, p=0.043; and 96.6% vs 86.4%, p=0.016)despite being statistically similar preoperatively. The 5-year cause-specific survival rate of those who underwent PG was 100% excluding relapse cases. The 5-year overall survival rates were 86% in those who underwent PG and 67%in those who underwent NG, although they differed significantly. Partial gastrectomy may be a valid surgical procedure that may yield better prognosis compared to that with normal gastrectomy for elderly patients with Stage ⅠA gastric cancer.

Abstract
BACKGROUND AND PURPOSE It is reported that simulation computed tomography colonography(S-CTC), which combines CTC and 3-dimensional(3D)vascular imaging, is useful in colorectal cancer surgery. However, it is difficult to create 3D vascular images using non-contrast CT. Laparoscopic transverse colectomy is said to be technically difficult. Mini-laparotomy surgery for mid-transverse colon cancer is quite easy to perform. However, exact D2 lymph node dissection is very difficult. We present a case of D2 lymph node dissection during mini-laparotomy transverse colectomy performed using S-CTC, which involves the creation of 3D vascular images using non-contrast CT. PATIENT AND METHOD The patient was a 77-year-old man with transverse colon cancer located in the mid-transverse colon, cT2N0M0, Stage Ⅰ. He had coexisting chronic renal failure. Non-contrast CT was performed prior to surgery, and the images were processed using workstation Zaiostation2. RESULTS Both the artery and the vein created from non-contrast CT could be visualized clearly until the marginal vessels. Using noncontrast S-CTC in combination with CTC and 3D artery imaging, it was identified that the dominant artery was the left branch of the middle colic artery(MCA Lt), while the right branch of the MCA(MCA Rt)and accessory MCA(AMCA)were 10 cm or more apart. The fusion of 3D artery and vein imaging made it evident that the vein accompanying MCA Lt branched from the superior mesenteric vein. Using non-contrast S-CTC, D2 lymph node dissection, dissection of the branching root of MCA Lt and the vein at the same level was simulated. Thus, mini-laparotomy transverse colectomy was performed through a 7 cm incision, in accordance with the simulation. CONCLUSION Non-contrast S-CTC was useful for performing D2 lymph node dissection during mini-laparotomy transverse colectomy.

Abstract
High-frequency ultrasonic imaging with improved spatial resolution has gained increasing attention in the field of biomedical imaging. Sensitivity of transducers plays a pivotal role in determining ultrasonic image quality. Conventional ultrasonic transducers are mostly made from lead-based piezoelectric materials that may be harmful to the human body and the environment. In this study, a new (K,Na)NbO3-KTiNbO5-BaZrO3-Fe2O3-MgO (KNN-NTK-FM) lead-free piezoelectric ceramic was utilized in developing eco-friendly transducers for high-frequency biomedical ultrasonic imaging applications. A needle transducer with a small active aperture size of 0.45 × 0.55 mm2 was designed and evaluated. The fabricated transducer exhibits great performance with a high center frequency (52.6 MHz), a good electromechanical coupling (keff ∼ 0.45), a large bandwidth (64.4% at -6 dB), and a very low two-way insertion loss (10.1 dB). Such high sensitivity is superior to those transducers based on other lead-free piezoelectric materials and can even be comparable to the lead-based ones. Imaging performance of the KNN-NTK-FM needle transducer was analyzed by imaging a wire phantom and an agar tissue-mimicking phantom. Imaging capabilities of the transducer were further demonstrated by ex vivo imaging studies on a porcine eyeball and a rabbit aorta. The results suggest that the KNN-NTK-FM piezoceramic has many attractive properties over other lead-free piezoelectric materials in developing eco-friendly highly sensitive transducers for high-frequency biomedical ultrasonic imaging applications.

Abstract
BACKGROUND The clinical findings of early anal gland carcinoma (AGC) have not been well delineated because AGC is a rare malignancy usually diagnosed at an advanced stage. Knowledge of the characteristic findings will be helpful for both diagnosis and determination of the treatment options for early AGC. CASE PRESENTATION A 62-year-old man was referred to our hospital for treatment of a rectal submucosal tumor (SMT) detected during a medical checkup at another hospital. Trans-sacral resection of the tumor was performed under the diagnosis of a rectal benign cyst. Pathological examination of the resected tumor showed a mucin-producing adenoma. About 14 months later, a new cystic lesion was found by follow-up examination, and trans-sacral resection of the tumor was performed again. The second pathological diagnosis was a mucinous adenocarcinoma with a possible remnant tumor at the local site. After providing sufficient informed consent, the patient underwent intersphincteric resection (ISR) of the rectum to preserve anal function. The final diagnosis was mucinous adenocarcinoma of the anal gland, T1N0M0. The patient remained alive without recurrence or complications for 6 years 7 months postoperatively. CONCLUSION We have herein reported a case of early AGC with a characteristic SMT-like appearance. Because the anal gland is located within both the submucosal layer and the internal sphincter muscle, ISR may be selected when the tumor is limited to inside the gland.

Abstract
740 Background: The FOLFOX with bevacizumab (B-mab) has been established as a standard first-line therapy for metastatic colorectal cancer (mCRC), and OPTIMOX1 study suggested that stop and go strategy for oxaliplatin reduced peripheral sensory neuropathy. The CapeOx is one of the standard treatments for mCRC that has been proven to be as effective as the FOLFOX regimen. Thus we accessed the efficacy and safety of the combination of intermittent CapeOx + B-mab as a first-line therapy in patients with mCRC in this trial. Methods: Eligibility criteria included ECOG PS: 0–1, No Peripheral neuropathy ( < Grade 1). Patients received CapeOX (oxaliplatin 130mg/m2, capecitabine 2000mg/m2 + B-mab 7.5mg/kg) q3 weeks for 5 cycles, maintenance without oxaliplatin for 5 cycles, and reintroduction CapeOX + B-mab for 5 cycles until progression. Primary endpoint was Progression Free Survival (PFS). Results: Between March 2011 and August 2013, 55 pts were enrolled. Baseline characteristics were median age of 67 years (range, 20–83); PS 0/1 (49/6 pts); male/female (33/22 pts), colon/rectum (28/27pts) and metastatic lesion liver/lung/lymph nodes (32/18/21 pts). A total of 47 pts were evaluated as Par Protocol Set population. 38 pts moved from initial CapeOX to maintenance Capecitabine. 20 pts moved to CapeOx reintroduction. Median PFS was 14.7months (95%CI, 8.6–19.5) and Median TTF was 12.3 months (95%CI, 10.3–14.3). Best overall response rate was 48.0%. Oxaliplatin reintroduction rate was 57.4%. Main grade 3/4 toxicity were: neutropenia (1 pt), anemia (1 pt), peripheral neuropathy (1 pt), allergic reaction of oxaliplatin (1 pt), deep vein thrombosis (1 pt), nausea (1 pt), hand-foot syndrome (1 pt), and hypertension (1 pt). Conclusions: This study met its primary endpoint PFS. CapeOx intermittent oxaliplatin indicated to reduce incidence of severe neutropenia and peripheral sensory neuropathy. The results suggested that our treatment strategy was well tolerate and effective for first line therapy in mCRC, and maintenance duration for 5 cycles, was reasonable.

Abstract
AIMS The aim of this study was to evaluate the correlation between Salter's criteria and Kalamchi's classification of avascular necrosis in patients treated for developmental dysphasia of the hip (DDH). PATIENTS AND METHODS The study involved a retrospective analysis of 123 patients (123 hips) with DDH treated by operative and non-operative reduction before the age of two years, with a minimum follow-up of ten years. Salter's criteria (S1 to S4) were determined from radiographs obtained at one to two years post-reduction, whilst the Kalamchi grade was determined from radiographs obtained at ten or more years of age. Early post-reduction radiographs were also used to evaluate the centre-head distance discrepancy (CHDD) and the occurrence of a dome-shaped deformity of the proximal femoral metaphysis (D-shaped metaphysis). The prognosis was described as good (Kalamchi grade K0 or KI), fair (Kalamchi grade KII) or poor (Kalamchi grade KIII or KIV) for analysis and correlation with the early Salter criteria, CHDD and D-shaped metaphysis. RESULTS S1 and S2 criteria were predictive of a poor prognosis. The outcome following S3, S4 and S3 + S4 varied; 18 (40%) had a good prognosis, 17 (38%) a fair prognosis and ten (22%) a poor prognosis. A CHDD ≥ 10% and a D-shaped metaphysis were also predictive of a poor prognosis. CONCLUSION The Salter criteria were predictive of the Kalamchi grade of avascular necrosis in patients with DDH aged ten or more years after reduction of the hip.

Abstract
OBJECTIVES To estimate the annual prevalence of different diagnostic categories by age, breed and sex in insured cats in Japan for which veterinary care claims had been made, and to identify if there is a pattern in these host factors. MATERIALS AND METHODS Data from 48,187 cats insured for veterinary care in Japan in the period from April 2012 to March 2013 comprising 26,003 males and 22,184 females were analysed to calculate the annual prevalence of 18 diagnostic categories of disease by age, breed and sex. RESULTS The prevalence was highest for urinary system disorders (12·2% for males and 10·0% for females), followed by digestive disorders (11·6% for males and 10·7% for females) and dermatological diseases (8·7% for males and 9·0% for females). The male cats had a higher prevalence than female cats for most diagnostic categories. The prevalence of cardiovascular, urinary, endocrine and neoplastic disorders increased with age; infectious and parasitic diseases had high prevalence at young ages, and the prevalence of respiratory, musculoskeletal disorders and injuries had bimodal peaks. Dermatological disorders had a high prevalence at all ages. A large variation in prevalence was observed between breeds for otic, dermatological, dental and cardiovascular disorders. CLINICAL SIGNIFICANCE The findings can be used to increase awareness of patterns of health disorders in different categories of cat.

UNLABELLED Essentials A consensus methodology for assessing the effects of antiplatelet agents has not been established. Measuring platelet thrombus formation (PTF) for evaluating antiplatelet effects was assessed. PTF differentially reflected antiplatelet effects compared to other tests. PTF may be associated with the severity of carotid or intracranial arterial stenosis. Click to hear a presentation on platelet function testing in the clinic by Gresele and colleagues SUMMARY Background A consensus methodology for assessing the effects of antiplatelet agents has not been established. Objective We investigated the usefulness of directly measuring platelet thrombus formation (PTF) using a microchip-based flow chamber system for evaluating antiplatelet therapy. Patients/Methods Platelet thrombus formation in the whole blood of 94 patients with ischemic cerebrovascular disease treated with clopidogrel and/or aspirin was measured in a flow chamber system at a shear rate of 1500 s(-1) and was compared with the results of assays for agonist-induced platelet aggregability, phosphorylation of vasodilator-stimulated phosphoprotein, platelet p-selectin expression (PS), and platelet-monocyte complexes. Results In all patients tested, area under the flow pressure curve (AUC10), which represents platelet thrombogenicity, showed weak correlation with platelet aggregation induced by either adenosine diphosphate or collagen. In addition, AUC10 was lower in patients treated with dual antiplatelet therapy (median 79.4) compared with patients treated with aspirin or clopidogrel alone (217.7 and 301.0, respectively), whereas the parameters evaluated by the other assays did not reflect the combined treatment efficacy. In clopidogrel monotherapy patients, AUC10 was associated with the severity of arterial stenosis (R(2) = 0.127, β = 1.25), and AUC10 and PS were higher in patients with severe carotid or intracranial arterial stenosis than in those with mild stenosis. Conclusions Platelet thrombus formation measurement using a flow-chamber system was useful for evaluating the efficacy of treatment with aspirin and clopidogrel, both alone and in combination. The present findings indicate that high residual platelet thrombogenicity in patients treated with clopidogrel may be associated with the severity of carotid or intracranial arterial stenosis.

Abstract
The effect of low-carbohydrate diet (LCD) on body composition, especially fat mass, in obese individuals remains to be elucidated. We performed a meta-analysis to provide quantitative summary estimates of the mean change of body weight (kg) and fat mass (kg) in LCD comparing to those in control diet. Literature searches were performed using EMBASE, MEDLINE and Cochrane Library until Dec 2014. Fourteen randomized controlled studies were included in this meta-analysis. Eight studies including very LCD (50 g carbohydrate or 10% calorie from carbohydrate) and seven studies including mild LCD (about 40% calorie from carbohydrate). Meta-analysis carried out on data of 1416 obese individuals, showed that LCD was associated with decrease in body weight (-0.70 kg [95% CI -1.07/-0.33]) or fat mass (-0.77 kg [-1.55/-0.32]). Subgroup meta-analysis of studies in over 12 months suggested that LCD was not associated with decrease in body weight (-0.44 kg [-0.94/0.07]), but LCD was associated with decrease in fat mass (-0.57 kg [-1.05/-0.09]). In addition, very LCD was associated with decrease in fat mass (-0.97 kg [-1.50/-0.44]), but mild LCD was not associated with decrease in fat mass (-0.43 kg [-1.15/0.33]). LCD, especially very LCD, might be effective for decrease in fat mass in obese individuals. © 2016 World Obesity.

Abstract
We encountered a 62-year-old female patient with a distinctive pancreatic myoepithelial hamartoma characterized by dilated loops formed by pancreatic branch ducts. The patient, who experienced recurrent acute pancreatitis caused by pancreatic juice stasis, underwent subtotal stomach-preserving pancreatoduodenectomy, achieving remission of pancreatitis. Computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) demonstrated a honeycomb appearance of the pancreatic head, consisting largely of loop-forming dilated pancreatic branch ducts. Radiography of resected specimens demonstrated a tortuous main pancreatic duct that narrowed in the head, but communicated with the pancreatic branch ducts forming intricate loops within the lesion. Histologic examination showed dilated pancreatic ducts embedded in thick layers of smooth muscle, leading to a diagnosis of myoepithelial hamartoma. Her son shared a similar clinical course, radiologic findings, and histopathologic findings with his mother. MRCP demonstrated a honeycomb appearance of the pancreatic head in her daughter, who complained of persistent diarrhea. To our knowledge, this is the first English-language reports of such a myoepithelial hamartoma of the pancreas showing familial occurrence.

Abstract
A 65-year-old woman underwent iliocecal resection for cecal cancer. During post-operative follow-up, she was diagnosed with metastasis to the abdominal wall and a curative resection was performed. After 12 courses of adjuvant chemotherapy with a modified combination of folinic acid, 5-fluorouracil, and oxaliplatin (mFOLFOX6), recurrence was noted in the lung. A curative resection was successfully performed and she was subsequently treated with bevacizumab and a combination of folinic acid, 5-fluorouracil, and irinotecan (FOLFIRI). One year after surgical resection, recurrence in the remnant lung was diagnosed. Because of the KRAS mutation, she could not be treated with anti-epidermal growth factor antibodies. The metastatic lung tumor continued to enlarge. Therefore, we selected regorafenib as third-line chemotherapy. After treatment with regorafenib, the size of the target lesion decreased significantly.

Abstract
AIMS A close association between heart rate-corrected QT interval (QTc) and albuminuria in people with Type 2 diabetes has been reported in cross sectional studies. The aim of this study was to evaluate the relationship between QTc and change in urine albumin excretion (UAE) or progression of albuminuria in people with Type 2 diabetes. METHODS We measured QTc in 251 consecutive people at baseline. We performed a 5-year follow-up cohort study to assess the relationship between QTc and change in UAE, defined as an increase of UAE/follow-up duration (year), or progression of albuminuria, defined as an increase in the category of diabetic nephropathy. RESULTS During follow-up, 23 of 151 people with normoalbuminuria and 13 of 73 people with microalbuminuria at baseline had progression of albuminuria. Multiple regression analysis demonstrated that QTc was independently associated with change in UAE (β = 0.176, P = 0.0104). Logistic regression analyses showed that QTc was a risk marker for progression of albuminuria [odds ratio per 0.01-s increase in QTc 1.35, 95% confidence interval (CI) 1.11-1.66, P = 0.0024] after adjusting for confounders. According to the receiver operator characteristic (ROC) analysis, the optimal cut-off point of QTc for progression of albuminuria was 0.418 s [area under the ROC curve 0.75 (95% CI 0.66-0.82), sensitivity = 0.86, specificity = 0.56, P < 0.0001]. CONCLUSIONS Heart rate-corrected QT interval could be a novel risk marker for progression of albuminuria in people with Type 2 diabetes.
