This trial evaluated the superiority of intraoperative wound irrigation (IOWI) with aqueous povidone-iodine (PVP-I) compared that saline for reducing incidence surgical site infection (SSI).IOWI PVP-I is recommended prevention SSI by World Health Organization and Centers Disease Control Prevention, although evidence level low.This single institute in Japan, prospective, randomized, blinded-endpoint was conducted to assess IOWI comparison clean-contaminated wounds after gastroenterological...
The study aimed to evaluate the impact of sarcopenia on short- and long-term outcomes for laparoscopic colorectal cancer surgery. Study participants were 209 patients who underwent surgery any stage between 2016 2017. Skeletal muscle indices calculated with preoperative computed tomography. Patients divided into sarcopenic non-sarcopenic groups based index cut-off values variables compared. prevalence was 41.1%. Sarcopenic experienced shorter operative times a lower incidence surgical site...
Brittle materials, such as silicon, silicon carbide and sapphire have been conventionally sliced for wafers by a multi-wire saw method with slurry in industrial fields. Recently, the fixed diamond abrasive wire has available commercial product at acceptable cost, high slicing performance is expected compared normal slurry. However, there still remain some problems bad working environment abrasives, cleaning cost of wafers, crack generation on surface large kerf loss against wafer thickness....
Genome‑wide DNA hypomethylation is the most common molecular feature in human cancers associated with chromosomal instability (CIN), which involved mechanisms that regulate pancreatic cancer (PC) metastasis. It was investigated whether genome‑wide affects phenotype PC via CIN vitro, and its significance on biological behavior of verified. The relative demethylation level (RDL) long interspersed nucleotide element‑1 (LINE‑1) cell lines used to characterize using methylation‑specific...
Combined treatment with bevacizumab and trifluridine/tipiracil (TAS-102) leads to an increased chance of survival in patients refractory metastatic colorectal cancer (mCRC); however, this is associated frequency severe neutropenia (number neutrophils <1,000), which should ideally be managed without dose delays. The present study provided a retrospective review 35 mCRC, aimed elucidate the benefits prophylactic pegfilgrastim for neutropenia. Patients received TAS-102 (35 mg/m2) orally twice...
Parastomal hernia (PH) is a common complication of ileal conduit diversions. The Sugarbaker technique has lower recurrence rate than the keyhole (KH) and typically preferred. However, it may not be feasible in some cases because anatomical features including length torsion ureter. An 80-year-old woman with complaints abdominal distention was diagnosed PH 5 years after radical cystectomy. Computed tomography revealed 90 × 20-mm muscular layer defect on cranial side conduit. Therefore, we...
Nivolumab monotherapy is a standard treatment of metastatic gastric cancer, and this type cancer involves vascular endothelial growth factor (VEGF) signaling in the tumor immunological environment. The subgroup analysis ATTRACTION‑2 trial revealed that prior with ramucirumab (RAM), VEGF inhibitor, affected therapeutic effect nivolumab. present retrospective study aimed to review patients who were treated paclitaxel (PTX) RAM followed by A total 29 PTX + as second‑line treatment, nivolumab...
385 Background: Despite success in the HER2 targeted therapies for metastatic gastric cancer patients, conventional assessment of status tumor tissue specimens is still under debate. Methods: Twenty-seven patients with were treated according to histological status. On-chip sorting system was used isolation circulating cells (CTCs) before treatments. Epithelial mesenchymal transition (EMT) assessed by vimentin and cytokeratin. DNA extracted from CTCs applied gene panel 409 related genes. The...
To study graft-versus-host reaction (GVHR) in small-bowel transplantation and its underlying mechanisms to find methods for circumventing GVHR, we used an unidirectional GVHR model which F1 Lewis (LEW) x Wistar King A (WKA) hybrid rats received transplants from either LEW or WKA parent rats. The survival time of that full-length was 16.3+/-2.1 days 18.2+/-3.4 days, respectively. When one-quarter small bowel transplanted recipient, the significantly longer at 44.0+/-23.4 compared with had...
Abstract Gastric and bile acid reflux leads to chronic inflammation, resulting in methylation alterations Barrett’s esophagus (BE) together with chromosomal instability (CIN). We investigated DNA hypomethylation following exposure confirmed its significance BE-related carcinogenesis by inducing CIN vitro. OACP4C, an esophageal cancer cell line, CP-A, a non-dysplastic line originating from BE, were exposed acidic conditions using deoxycholic acid. CP-A exhibited substantially increased of...
In large-area electron beam (EB) irradiation method developed recently, high energy density of EB can be obtained without focusing the beam. Therefore, wide area material surface melted instantly, and efficient finishing is possible. Moreover, functions such as corrosion resistance water repellency metal molds were improved by irradiation, since thin resolidified layer was formed on surface. It expected that thick modified effective to maintain their for long-term. control prediction...
Abstract Background Percutaneous radiofrequency ablation (RFA) is an effective treatment for hepatocellular carcinoma (HCC), but delayed thermal damage can cause diaphragmatic hernia (DH). Surgery recommended DH, and open surgery widely accepted. This report presents a case of laparoscopic strangulated DH that occurred after RFA. Case presentation An 80-year-old woman with history hepatitis C-induced liver cirrhosis HCC was admitted to our institution owing sudden-onset intense epigastric...
In large-area electron beam (EB) irradiation method, uniformly high energy density can be obtained without focusing the beam. Large-area EB used for melting and evaporating metal surface instantly. It was clarified that efficient finishing of mold steels, ceramics cemented carbides possible by irradiation. Furthermore, tip convex shape often rounded after with remarkable material removal at tip. This phenomenon is probably caused due to heat accumulation electrons concentration However,...
Malignant tumors in the sinonasal region are rare and account for only 0.2–0.8% of all cancers 1–3% head neck carcinomas. Among confirmed cases, involvement sphenoid sinus is even rarer, accounting 2–3% paranasal (Osguthorpe et al., 1994; Esposito 2006; DeMonte 2000). Neuroendocrine carcinoma as a primary lesion very rare; due to its rarity, no standard treatment has been established. Staining thyroid transcription factor-1 (TTF-1) shown be useful definite diagnosis lung tumors. However,...

Abstract Background Intestinal ultrasound (IUS) is non-invasive and can assess all segments of the colon even in severe ulcerative colitis (UC). While IUS estimate endoscopic findings UC, terms Treat to Target strategy, it remains a crucial clinical question whether changes with therapeutic interventions predict treatment efficacy patient prognosis. Here, we investigated if comparing at baseline 3 months after starting molecular-targeted medication (MTM) steroid-free remission (SFCR) UC 6...
胸腺腫肝転移の画像検査の特徴的所見および外科的切除の有効性に関する詳細な報告は少ない.症例は79歳,男性.肝腫瘍の精査加療目的に当院を紹介受診した.充実成分と嚢胞成分を有する肝腫瘍に対して肝切除術を行った.病理組織学的検査で胸腺腫肝転移と診断されたため,肝切除術5カ月後に前縦隔腫瘍摘出術および転移性肺腫瘍切除術を施行,病理組織学的検査は胸腺腫および胸腺腫肺転移であった.術後補助化学療法は施行していないが,術後42カ月無再発生存中である.胸腺腫の血行性転移は頻度が低く,画像検査所見の特徴は明らかではない.肝臓の嚢胞性病変は様々な鑑別疾患が挙げられるが,胸腺腫肝転移も嚢胞成分を伴っていることがある.胸腺腫肝転移に対する外科的切除が有用である症例が存在することが本症例から示唆された.
Body mass index(以下,BMIと略記)35kg/m2以上の高度肥満を伴う大腸癌に対し腹腔鏡下手術を施行した4例を検討した.数値を中央値(範囲)で示す.年齢64(54-80)歳,男性2例,女性2例,BMI 41.6kg/m2(35.6-48.7).2例において術前のエネルギー制限を行った.術式は回盲部切除術,低位前方切除術,S状結腸切除術,結腸左半切除術それぞれ1例.手術時間393(335-688)分,術中出血量173.5(40-1,790)mL,術後在院日数10(7-63)日.1例で手術創の追加,2例でポートの追加を行った.低位前方切除術の症例において出血制御不能のため開腹移行し,術後に縫合不全を認めた.高度肥満を伴う大腸癌症例に対する腹腔鏡手術において,手術操作上の困難性を克服することが重要と考えられた.また,術前減量の意義については症例集積のうえ今後も検討を要する.
当院で経験した肛門管扁平上皮癌6例に対する化学放射線療法の治療成績を後方視的に検討した.臨床病期はIが1例,IIIAが1例,IIIBが1例,IIICが3例であった.初回治療として1例に局所切除が施行された.併用化学療法はfluorouracil+mitomycin Cが4例,fluorouracil+cisplatinが2例であった.Grade3以上の有害事象を3例に認め,内訳は好中球減少1例,皮膚炎1例,嘔気1例であった.自然肛門は4例で温存可能であった.他2例は腫瘍による腸閉塞のため,化学放射線療法開始前に人工肛門を必要とした1例と,化学放射線療法後肛門機能廃絶のため人工肛門造設術を施行した1例であった.治療成績は全例で完全奏効が得られ,無再発生存中である.肛門管扁平上皮癌に対する化学放射線療法は,有害事象に注意を要するが根治が期待される有用な治療法と考えられた.
症例は60歳代,男性.腹痛のため前医を受診し,S状結腸憩室穿孔と診断され当院へ紹介された.HincheyIIIのS状結腸憩室炎・穿孔と診断し,腹腔鏡下ハルトマン手術を施行した.術後合併症なく経過し,初回手術から4ヵ月後に腹腔鏡下ハルトマンリバーサル手術を行った.人工肛門を直視下に閉鎖した後に,腹腔鏡下に直腸断端の癒着を剥離した.直腸を授動した後に,結腸と直腸を端側吻合した(single stapling technique).術後経過は良好で,合併症なく退院した.S状結腸憩室穿孔に対するハルトマン手術,またその消化管再建術であるハルトマンリバーサル手術を腹腔鏡下に行うことの有用性が報告されているものの,本邦での報告は少ない.文献的な考察を含め報告する.
