The curability of chemotherapy-resistant hepatoblastoma (HB) largely depends on the achievement radical surgical resection. Navigation techniques utilizing indocyanine green (ICG) are a powerful tool for detecting small metastatic lesions. We herein report patient who underwent second living donor liver transplantation (LDLTx) multiple recurrent HBs in graft following metastasectomy peritoneal dissemination with ICG navigation. initially presented ruptured HB at 6 years age and 3 resections...
Infants born in Japan are reported to have a low incidence of necrotizing enterocolitis (NEC) among countries, and these differences remained significant after adjusting for common clinical factors. To investigate the impact ethnic background, we compared NEC between infants those mothers Japanese ethnicity California. Preterm 2008 2019 at 22–29 weeks gestational age were analyzed retrospectively. Four groups analyzed: (JP), California (JP-J), with but United States or another country...
Beckwith–Wiedemann syndrome (BWS) is a congenital overgrowth that occasionally associated with hyperinsulinemic hypoglycemia (HH) in the neonatal period. Sotos (SS) and Kabuki (KS) are other malformation syndromes may be complicated HH, however, detailed clinical characteristics of HH accompanied these remain unclear. We herein conducted nationwide questionnaire survey Japan. sent primary concerning experience for to 347 perinatal care institutions. As result, 222 departments or hospitals...
Background: The curability of hepatoblastoma (HB) largely depends on the achievement radical surgical resection, even for metastatic tumors. However, extension tumor when viewed through an endoscope with conventional white-light mode is often unclear. Advancements in imaging technology utilizing indocyanine green (ICG) have facilitated precise resection HBs, owing to longer retention ICG such lesions than other normal tissues. Case: We utilized loaded PINPOINT system (NOVADAQ Technologies,...
To evaluate the use of donor-derived cell-free DNA (dd-cfDNA) in diagnosing graft injuries Japanese liver transplantation (LTx), including family-related living donors.
Growing evidence suggests a relationship between antibody-mediated rejection (AMR) and early graft failure due to previously unknown etiology in liver transplantation (LTx). We herein report 3-year-old boy who developed rapid de novo donor-specific antibody (DSA)-driven AMR week after living donor LTx, requiring second transplant on the 10th day first LTx. The pathology of showed massive necrosis zone 3 along with positive C4d inflammatory cell infiltrates portal areas. mean fluorescence...
No standard diagnostic method or surgical treatment for congenital isolated hypoganglionosis (CIHG) has been established. This study aimed to analyze the clinical outcomes of patients with CIHG and identify best interventions provided thus far. Data on in 19 were collected between 1992 2020, including type enterostomy, revision, length intestines. Ganglion cells myenteric plexus enumerated using Hu C/D staining. The ratio small intestine its height was defined as intestinal (IR). assessed...
Feral raccoons (Procyon lotor) have been increasing in number since 1979 and are currently subject to pest control Hokkaido. One of the reasons for increase numbers is thought be high reproductive potential raccoons, but little known about their reproduction. The main aim this study was clarify seasonal changes spermatogenesis peripheral testosterone concentration In present study, external characteristics histology testis epididymis plasma were investigated 68 feral, male culled once a...
Extrahepatic congenital portosystemic shunts (CPSSs) can be occluded by surgical or endovascular approaches. However, when the estimated portal vein (PV) pressure after closure is high enough to induce symptoms associated with hypertension, partial recommended avoid life-threatening events. In this study, we attempted laparoscopic of a CPSS in two patients. Along intraoperative real-time measuring PV and angiography, was performed achieve ≤25 mmHg. Subsequently, intrahepatic system grew both...
症例は62歳,女性.上腹部痛と発熱を主訴に来院した.腹部X線では明らかなfree airを認めなかったが,腹部CTにて胃前庭部前壁を貫通して延びる約3cmの線状のhigh densityの異物と周囲のfree airを認め,魚骨による胃穿孔と考え,緊急手術を行った.開腹すると胃前庭部前壁を索状異物が貫いており,異物を除去,穿孔部に小網を充填した.異物は約3.5cmの中空の索状異物で,問診と肉眼的所見より魚骨と考えられた.われわれは2001年から2010年の10年間の魚骨による消化管穿孔・穿通症例446例を解析した.胃穿孔は35例(7.8%)と少なかった.近年はCTにより術前正診率が向上している.今回われわれは比較的まれな魚骨による胃穿孔の1例を経験したので文献的考察を加えて報告する.
The raccoon (Procyon lotor), indigenous to North America, has naturalized in Japan as an invasive alien species, having been introduced into the country 1970s. In Hokkaido, northernmost island of Japan, feral raccoons have increasing number and spreading throughout island. age at onset puberty for is important estimating individual lifetime reproductive success population growth. present study investigated timing potential factors affecting male Hokkaido. External characteristics histology...
We report two Japanese patients with Schinzel-Giedion syndrome. When polyhydramnios is observed, additional fetal findings such as overlapping fingers, hydrocephalus, hydronephrosis, and very characteristic facial appearance comprising high, prominent forehead, hypertelorism, depressed nasal root may suggest
Abstract Background To investigate the feasibility of fourth arm da Vinci Si system for robot‐assisted partial nephrectomy (RAPN). Methods Fifty‐eight consecutive patients underwent RAPN with same port placements. After reviewing surgical videos and records, 38 showing usefulness were categorized into Group A those not B. The background data, tumor characteristics, perioperative outcomes compared between groups. Results B had a larger proportion tumors located on inner side kidney, console...
Considering that some biliary atresia (BA) survivors with native liver have reached reproductive age and face long-lasting complications, specific attention needs to be paid pregnant cases. This study aimed investigate the relationship between function, perinatal outcomes, prognosis. A database review was conducted identify BA cases data, clinical information on BA-related complications analyzed. Perinatal serum cholinesterase (ChE) levels, model for end-stage liver-disease (MELD) score,...
症例は54歳,男性.前立腺癌の診断にて2014年6月ロボット支援腹腔鏡下前立腺全摘除術を施行された.術後経過は良好であったが,術後3カ月目に頻尿と血尿が出現した.超音波検査とCT検査で膀胱内に7mmの結石陰影を認め,膀胱鏡で膀胱尿道吻合部9時の位置に可動性のない結石がみられた.以上より膀胱結石と診断し経尿道的膀胱結石破砕術を行ったが,結石表面が破砕されるとロボット支援手術時に用いたHem-o-lok clipが内部から出現した.クリップは鉗子で除去し結石は全て破砕摘出し手術終了した.術後経過は良好でその後クリップの迷入はみられていない.Hem-o-lok clipはロボット支援腹腔鏡下前立腺全摘除術時の側茎処理や腹腔鏡下手術時の血管処理などに用いられることが多い.ロッキング機構があり脱落しにくい特徴を持つが,稀に膀胱内へ迷入し,結石を形成した報告や膀胱粘膜びらんを合併し吻合部狭窄をきたした報告がみられる.今回我々の経験した結石を伴うクリップ迷入症例を若干の文献的考察を加えて報告する.

Abstract Background Postoperative recurrence of tracheoesophageal fistula (TEF) is a frequent complication in the repair esophageal atresia (EA). Based on recent etiologic classification, TEF that develops different new pathway from original one categorized as an acquired TEF. The TEFs fall into this category have been reported to be refractory and their mechanisms not fully understood. Here, we report complicated case derived mediastinitis after developed anastomotic stricture. contained...
