Buried bumper syndrome in percutaneous endoscopic gastrostomy with a jejunal extension tube in patients undergoing levodopa-carbidopa intestinal gel treatment.

Background: Levodopa-carbidopa intestinal gel (LCIG) treatment is an effective Parkinson's disease (PD) treatment that requires percutaneous endoscopic gastrostomy with a jejunal extension tube (PEG-J). Buried bumper syndrome (BBS) is an uncommon but significant complication of PEG-J for LCIG. Case presentation A 71-year-old man had been undergoing LCIG therapy for PD since a PEG-J was implemented at our department two years previously.

Hemodynamic predictors of negative false lumen remodeling after frozen elephant trunk for acute aortic dissection.

Objective: We evaluated the blood flow within the downstream aortic false lumen after frozen elephant trunk repair for acute aortic dissection and identified hemodynamic predictors of false lumen expansion and negative false lumen remodeling using four-dimensional flow magnetic resonance imaging.

Methods: Thirty-one patients (Stanford type A, n = 28; Stanford type B, n = 3) with patent false lumen who underwent frozen elephant trunk procedures for acute aortic dissection were included in this observational study. Each patient underwent computed tomography during the follow-up period and four-dimensional flow magnetic resonance imaging within 3 postoperative months.

Simulation to determine the approach of transcatheter aortic valve implantation in patients undergoing hemodialysis.

Purpose: The present study investigated potential access vessels in patients receiving hemodialysis who underwent surgical aortic valve replacement and determined which approaches were most suitable for performing transcatheter aortic valve implantation.

Methods: Consecutive patients undergoing hemodialysis with aortic valve stenosis who underwent surgical aortic valve replacement were included. Preoperative computed tomography data were analyzed to assess the vessel diameter and calcification.

Transcatheter aortic valve-in-surgical aortic valve for a patient with repeated healed endocarditis: a case report.

Background: Transcatheter valve replacement is contraindicated in patients with active infective endocarditis. However, few reports suggest that it could be beneficial for high-risk surgical patients with healed infective endocarditis. Here, we report a case of a surgical transcatheter aortic valve in a patient with healed repeated prosthetic valve endocarditis using a stentless valve.

Impact of laparoscopic surgery on short-term and long-term outcomes in elderly obese patients with colon cancer.

Background: Laparoscopic surgery is reported to be useful in obese or elderly patients with colon cancer, who are at increased risk of postoperative complications because of comorbidities and physical decline. However, its usefulness is less clear in patients who are both elderly and obese and may be at high risk of complications.

Methods: Data for obese patients (body mass index ≥25) who underwent laparoscopic or open surgery for stage II or III colon cancer between January 2009 and December 2013 were collected by the Japan Society of Laparoscopic Colorectal Surgery.

A protocol-based treatment for ruptured abdominal aortic aneurysm contributed to improving aorta-related mortality: a retrospective cohort study.

Background: Recent guidelines state that improving the survival rate of patients with ruptured abdominal aortic aneurysm (rAAA) requires a protocol or algorithm for the emergency management of these patients. We aimed to investigate whether introducing a protocol treatment for rAAA improves clinical outcomes compared with the pre-protocol strategy.

Methods: At our institution, 92 patients treated for rAAA between June 2008 and August 2022 were retrospectively analyzed.

Laparoscopic Heller myotomy with Dor fundoplication for esophageal achalasia treatment after distal gastrectomy and Billroth-II reconstruction.

Laparoscopic Heller myotomy with Dor fundoplication is the standard surgical treatment for esophageal achalasia. However, there are few reports on the use of this method after gastric surgery. We report a case of a 78-year-old man who underwent laparoscopic Heller myotomy with Dor fundoplication for achalasia after distal gastrectomy and Billroth-II reconstruction.

Therapeutic strategy aiming at R0 resection for borderline-resectable esophageal squamous cell carcinoma using induction chemotherapy with docetaxel, cisplatin, and 5-fluorouracil.

Objective: Treatment for borderline resectable (cT3br) esophageal squamous cell carcinoma (SCC) is currently undefined. This study aimed to analyze the outcome of treatment strategies including induction chemotherapy with docetaxel, cisplatin, and 5-fluorouracil (DCF) against T3br esophageal SCC.

Methods: A total of 32 patients with cT3br esophageal SCC enrolled in this study were treated with two cycles of DCF induction therapy.

Successful combined laparoscopic and thoracoscopic surgery for esophago-mediastinal fistulae.

Minimally invasive surgeries have been developed, not only for gastrointestinal cancer, but also for benign or emergency cases. We report the case of a 62-year-old male who underwent laparoscopic and thoracoscopic combined surgery for an esophago-mediastinal fistula caused by a press-through package. In the initial laparoscopic phase, transhiatal dissection of the lower thoracic esophagus and harvesting of the greater omentum were performed.

Strategy Treatment of cT4b Esophageal Squamous Cell Carcinoma Using Docetaxel, Cisplatin, and 5-Fluorouracil.

Background/aim: This study analyzed the outcomes of docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy and DCF plus concurrent radiotherapy (DCF-RT), both followed by conversion surgery, if possible, in patients with cT4b esophageal cancer.

Patients And Methods: Forty-six patients with cT4b esophageal cancer, including borderline cT4b lesions, were eligible. Borderline cT4b lesions were treated with induction DCF therapy.

Ehlers-Danlos syndrome type IV with a novel COL3A1 exon 14 skipping variation confirmed by Tohoku Medical Megabank Organization genomic database.

A novel COL3A1 variant was identified in a Japanese case of Ehlers-Danlos syndrome type IV (EDS-IV) with a characteristic "Madonna" face, fragile uterus, and easy bruising in addition to a history of cavernous sinus fistula. We confirmed variable diameters of collagen fibrils in the dermis and decrease in type 3 collagen production from cultured fibroblasts. Genomic DNA sequencing of the COL3A1 region and COL3A1 cDNA sequence expressing in cultured fibroblasts identified that a nucleotide variation at c.
