Systemic lupus erythematosus associated with recurrent lupus enteritis and peritonitis

We describe the case of a 41-year-old woman with systemic lupus erythematosus (SLE) who suffered from repeated reversible lupus enteritis characterized by marked edematous thickening of the small intestine. Ultrasonography (US) and computed tomography (CT) manifested as an accordion-like appearance and a target-like appearance, respectively. Resolution of gastrointestinal tract wall thickening was observed on follow-up US performed a week after the increase in predinosolone (PSL). We conclude that careful evaluation of sonographic and radiographic findings helps to establish the diagnosis of lupus enteritis.Abbreviations CT Computed tomography - FANA Fluorescent antinuclear antibody - GI Gastrointestinal - SLE Systemic lupus erythematosus - US Ultrasound     

Alberta Stroke Program Early CT Score Calculation Using the Deep Learning-Based Brain Hemisphere Comparison Algorithm

ObjectivesThe Alberta Stroke Program Early Computed Tomography Score (ASPECTS) is a promising tool for the evaluation of stroke expansion to determine suitability for reperfusion therapy. The aim of this study was to validate deep learning-based ASPECTS calculation software that utilizes a three-dimensional fully convolutional network-based brain hemisphere comparison algorithm (3D-BHCA).Materials and MethodsWe retrospectively collected head non-contrast computed tomography (CT) data from 71 patients with acute ischemic stroke and 80 non-stroke patients. The results for ASPECTS on CT assessed by 5 stroke neurologists and by the 3D-BHCA model were compared with the ground truth by means of region-based and score-based analyses.ResultsIn total, 151 patients and 3020 (151 × 20) ASPECTS regions were investigated. Median time from onset to CT was 195 min in the stroke patients. In region-based analysis, the sensitivity (0.80), specificity (0.97), and accuracy (0.96) of the 3D-BHCA model were superior to those of stroke neurologists. The sensitivity (0.98), specificity (0.92), and accuracy (0.97) of dichotomized ASPECTS > 5 analysis and the intraclass correlation coefficient (0.90) in total score-based analysis of the 3D-BHCA model were superior to those of stroke neurologists overall. When patients with stroke were stratified by onset-to-CT time, the 3D-BHCA model exhibited the highest performance to calculate ASPECTS, even in the earliest time period.ConclusionsThe automated ASPECTS calculation software we developed using a deep learning-based algorithm was superior or equal to stroke neurologists in performing ASPECTS calculation in patients with acute stroke and non-stroke patients.     

Rare presentation of De Garengeot hernia treated by transabdominal preperitoneal hernia repair: A case report

We present a rare case of De Garengeot hernia treated with simultaneous laparoscopic appendectomy and transabdominal preperitoneal hernia repair. Our patient was an 85-year-old man with a bulging mass in the right groin. De Garengeot hernia was observed on contrast-enhanced CT. Urgent laparoscopy showed the distal part of the appendix passing through a right-sided femoral hernia. Laparoscopic appendectomy was performed, followed by transabdominal preperitoneal repair of the femoral hernia. Pathological examination revealed ischemic necrosis of the appendix. The patient's postoperative recovery was uneventful.     

Postpancreatoduodenectomy Hemorrhage Treated by Combined Transcatheter Arterial Embolization and Superior Mesenteric Artery to Iliac Artery Bypass: Report of a Case

Postpancreatectomy hemorrhage is a potentially life-threatening complication. We report herein our experience with a 65-year-old man with locally advanced pancreatic adenocarcinoma who underwent pancreatoduodenectomy with lymphadenectomy following neoadjuvant chemoradiotherapy. On postoperative day 45, he developed massive hematemesis. Angiography revealed active bleeding from the common hepatic artery, and transcatheter coil embolization of that vessel was successfully performed. On postoperative day 64, he again developed massive hematemesis. Angiography revealed active bleeding from the proximal superior mesenteric artery. Immediately after coil embolization of that vessel, bypass grafting between the superior mesenteric artery and the right common iliac artery was performed, using a greater saphenous vein graft. The combination of embolization and bypass grafting is an option for treatment of bleeding from the superior mesenteric artery in an emergent situation.Key words: Superior mesenteric artery, Bleeding, Bypass, Pancreatoduodenectomy, Postpancreatectomy hemorrhagePostpancreatectomy hemorrhage (PPH) is a rare but life-threatening complication, often associated with the presence of a pancreatic fistula or intraabdominal abscess.¹ The mortality associated with arterial bleeding after pancreatoduodenectomy is reportedly between 14.3% and 30.7%.^2–6 With recent advances in interventional radiology techniques, transcatheter arterial embolization (TAE) has become an alternative to surgical treatment.^3,5,7,8 However, it may be difficult to treat these patients with interventional radiology techniques alone, given their often unstable condition. In addition, the inappropriate use of TAE for arterial bleeding, especially after pancreatoduodenectomy, can lead to end-organ infarction and subsequent infection. We report herein our experience with a patient who had bleeding from the superior mesenteric artery (SMA) after pancreatoduodenectomy. This patient was successfully treated using SMA coil embolization followed by creation of an SMA-iliac artery bypass using a greater saphenous vein graft.     

Strictureplasty for short duodenal stenosis in Crohn's disease

Involvement of the gastroduodenum is extremely rare in Crohn's disease. For obstructing duodenal Crohn's disease, bypass procedures have traditionally been selected. However, more recently, strictureplasty has become an acceptable surgical option. We treated two Crohn's disease patients with short proximal duodenal stenosis, using Finney-type strictureplasty. Their postoperative courses were uneventful and they have remained asymptomatic during follow-up periods of more than 5 years, and 4 months, respectively. Owing to the good clinical results of our two patients, we consider strictureplasty to be indicated for short proximal duodenal stenosis in Crohn's disease.
