Highlights
Diaphragm disease is a rare NSAIDs-induced injury of the small intestine.
Diaphragm disease is mostly surgically treated.
Diagnosis with double-balloon enteroscopy can be considered for diaphragm disease.
Background
Delayed arterial hemorrhage after pancreaticoduodenectomy is a life-threatening complication. There are no reports about infected aneurysms of the superior mesenteric artery after pancreaticoduodenectomy without clinically relevant pancreatic fistula.
Case presentation
A 78-year-old woman with borderline resectable pancreatic ductal adenocarcinoma involving the superior mesenteric arterial nerve plexus underwent pancreaticoduodenectomy with en bloc resection of the superior mesenteric vein and the superior mesenteric arterial nerve plexus after neoadjuvant chemotherapy. On postoperative day 14, she had bacteremia and sudden fever with chills. During the postoperative course, macroscopic abscesses or distinct infectious signs, including pancreatic fistula or bile fistula, were not present, but pylephlebitis was observed. After the antimicrobial treatment course, the patient was discharged. After 17 days, she was hospitalized for melena. Contrast-enhanced computed tomography showed a ruptured aneurysm of the superior mesenteric artery into the small intestine without a major intraabdominal abscess. E. coli was isolated from blood cultures. The patient was diagnosed with a ruptured infected aneurysm of the superior mesenteric artery. She was treated successfully with a covered stent by the cardiology team. There was no recurrence of bleeding at the 4-month follow-up, and the stent was patent in all subsequent computed tomography scans.
Conclusions
Endovascular repair using a covered stent was effective in palliating acute bleeding from an infected aneurysm of the superior mesenteric artery.
IntroductionThe therapeutic strategy for superficial nonampullary duodenal epithelial tumors remains controversial. We developed a novel surgical technique for superficial nonampullary duodenal epithelial tumors. We report the initial two cases managed with this method.Materials and surgical techniqueWe endoscopically confirmed the tumor location and circumferentially incised the seromuscular layer of the duodenum along it. After circumferential seromyotomy, the submucosal layer was expanded by endoscopic insufflation, and the target lesion was sufficiently lifted. The submucosal layer, including the target lesion, was stapled and resected after confirming the absence of problems with endoscopic passage. The seromuscular layer was continuously sutured to bury and reinforce the stapler line. Single‐incision laparoscopic surgery was performed in one case. The resected specimens measured 52 × 32 mm and 50 × 26 mm with negative surgical margins. Both patients were discharged without complications and demonstrated no evidence of stenosis.DiscussionCompared with previously reported procedures, this method of partial duodenectomy with seromyotomy for superficial nonampullary duodenal epithelial tumors is promising, simple, and safe.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
