Computed tomography (CT) colonography is increasingly recognized as a valuable modality for diagnosing colorectal lesions, however, the interpretation workload remains challenging physicians. Deep learning-based artificial intelligence (AI) algorithms have been employed imaging diagnoses. In this study, we examined sensitivity of neoplastic lesions in CT images. Lesion location and size were evaluated during colonoscopy large-scale database including dataset AI learning external validation...
The objective of this study was to assess prospectively the diagnostic accuracy computer-assisted computed tomographic colonography (CTC) in detection polypoid (pedunculated or sessile) and nonpolypoid neoplasms compare between gastroenterologists radiologists.This nationwide multicenter prospective controlled trial recruited 1,257 participants with average high risk colorectal cancer at 14 Japanese institutions. Participants had CTC colonoscopy on same day. images were interpreted...
Delayed postpolypectomy bleeding occurs more frequently after hot resection than cold resection.To elucidate the underlying mechanism, we performed a histological comparison of tissue and snare resections.This is prospective study, registered in University Hospital Medical Information Network (UMIN000020104).This study was conducted at Aizu Center, Fukushima University, Japan.Fifteen patients scheduled to undergo colorectal cancer were enrolled.On day before surgery, 2 mucosal resections...
This study was designed to evaluate the usefulness of 18-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) colonography in preoperative diagnosis tumors proximal obstructive colorectal cancers, which were defined as cancers that cannot be traversed colonoscopically.A whole-body PET/CT protocol for tumor staging and a CT integrated into one examination. No cathartic bowel preparation used before this Thirteen prospective patients with cancer examined. We compared...
The neutrophil‑to‑lymphocyte ratio (NLR) has been reported to be an independent prognostic factor of unresectable advanced or metastatic colorectal cancer (uCRC). However, few studies have documented changes in NLR during chemotherapy. current study analyzed whether a change chemotherapy patients with uCRC could used as biomarker. present retrospective enrolled 71 who received first‑line for between April 2012 and 2019. exclusion criteria were follows: Acute infection systemic inflammatory...
Abstract Anal canal cancer (ACC) has been reported to be an uncommon in Japan, as the USA, Europe, and Australia. This retrospective multi‐institutional study was conducted clarify characteristics of ACC Japan. First, histological type cases treated between 1991 2015 were collected. A detailed analysis anal squamous cell carcinoma (SCC) then conducted. The results types revealed that 1781 cases, 435 (24.4%) including seven adenosquamous carcinomas SCC 1260 (70.7%) adenocarcinoma. However,...
Sodium phosphate is a key component of bowel preparation regimen for colon capsule endoscopy (CCE), but may cause serious complications. The aim this study to evaluate the use Gastrografin, substituted sodium phosphate, in CCE preparation.In total, 29 patients (median age 64 years; 23 females) underwent CCE, covered by national health insurance system Japan. All had history laparotomy and/or previously incomplete colonoscopy. On day before examination, ingested 1 L polyethylene glycol +...
We evaluated the clinical usefulness and safety of transradial approach for transcatheter arterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC) compared that conventional transfemoral approach. The two groups (radial group, n = 177; femoral 150) cases were retrospectively regard to successful rate angiography or TACE, time required catheterizaiton complications. Hepatic TACE completed 174 (98.3%) 177 radial group. There was no intergroup difference...
Background and Study Aims Small polyps are occasionally missed during colonoscopy. This study was conducted to validate the diagnostic performance of a polyp‐detection algorithm alert endoscopists unrecognized lesions. Methods A computer‐aided detection (CADe) developed based on convolutional neural networks using training data from 1991 still colonoscopy images 283 subjects with adenomatous polyps. The CADe evaluated validation dataset including 50 short videos 1–2 (3.5 ± 1.5 mm, range 2–8...
Abstract Purpose Advances in endoscopic technology have led to the reevaluation of self-expandable metallic stent (SEMS) placement as a bridge-to-surgery (BTS) patients with obstructive colorectal cancer. In Japan, after inclusion SEMS BTS medical insurance coverage 2012, this procedure has been increasingly performed. However, transanal decompression tube (TADT) used BTS. We aimed retrospectively evaluate optimal strategy for left-sided cancer (OLCRC) by comparing and TADT emergency...
We conducted a study on three-dimensional computed tomography (CT) images, in particular CT air-contrast enema (CT enema), using multidetector-row (MDCT), to see whether is useful as preoperative examination for colorectal cancer. aimed evaluate the detectability of lesions and depth cancer invasion enema.292 patients (328 lesions) with were enrolled. After an adequate insufflation large intestine, MDCT scans performed. With data obtained by MDCT, we reconstructed images. images assessed...
Background and study aims Delayed bleeding is believed to occur less frequently after cold snare polypectomy (CSP), but this has not been validated in clinical trials. This aimed compare rates of delayed CSP hot (HSP). Patients methods We conducted a multicenter, randomized controlled trial. Participants scheduled undergo endoscopic resection colorectal polyps ≤ 10 mm were enrolled randomly assigned or HSP. Prophylactic clipping was performed at the endoscopists' discretion. The primary...
We report a case of rare complication in laparoscopic colectomy. A 55-year-old woman underwent laparoscopy-assisted transverse colectomy for colon cancer. On the 5th postoperative day, she developed bowel obstruction. Decompression by long intestinal tube failed to resolve She operative intervention. Abdominal exploration showed jejunal loop caused strangulation forming on an internal hernia through mesenteric opening at anastomotic colonic stumps, which had not been sutured during previous...
