Aortoesophageal fistula is a critical and life-threatening disease. The cardiovascular strategy for graft replacement has been widely discussed. However, the surgical strategy of esophageal resection and reconstruction for aortoesophageal fistula has rarely been discussed. The objective of this study is to establish a surgical strategy and procedure of esophageal resection and reconstruction for aortoesophageal fistula. Eleven patients with aortoesophageal fistula who underwent aortic graft replacement and esophagectomy between 2008 and 2015 at Kobe University Hospital were enrolled in this study...

Retroperitoneal fibrosis is a disease that may condition a severe involvement of various organs, mainly upper urinary tract, even causing renal insufficiency. It was first described by Albarran in 1905 and it is also known as Ormonds disease. The correct diagnosis includes, in many cases, the performance of one or more tests: CT scan, MRI, renal scan, etc. It is often necessary the insertion of double J catheters on percutaneous nephrostomy tubes with the aim to preserve renal function. Initial treatment is medical, based on corticoids, and , less frequent, immunosuppressive or chemotherapy drugs...

Type 1 diabetes is characterized by autoimmune destruction of pancreatic cells. Organ transplantation is an acceptable treatment for native organ failure. However, it is associated with several problems due to a number of reasons, such as the lack of appropriate donors and immunosuppression. In our present study, a novel model is presented for in vivo recellularization of acellular pancreas by implanting between the host pancreas and the adjacent omental flap. In this study, the pancreases were harvested and cannulated via the common bile duct and then, the scaffolds were acellularized by a detergent-based protocol...

Abdominal aortic graft-enteric fistula is an uncommon but grave complication. Acceptable early results of its management have been reported in recent years, but aortic stump disruption remains a dreaded problem in the remote period. This report describes a case of a 71-year-old male with graft-enteric fistula following after a distant abdominal aortic aneurysm repair. The patient underwent 1-stage operation with extra-anatomic bypass preceding the complete removal of the infected aortic graft and intestinal repair...

Catheter migration and omental wrap are the most common causes of catheter malfunction, which usually result in catheter removal or replacement. The conventional open surgery for catheter reposition has many disadvantages. A new tunnel is needed throughout the procedure of catheter replacement causing more pain and frustration to the patients. Another drawback is that the incidence of catheter migration after conventional catheter reposition surgery is still as high as it was before the procedure. Wang's forceps, an instrument commonly used in our peritoneal dialysis center, is easy and effective in catheter insertion and fixation...

PURPOSE: Over the past two decades, continuous ambulatory peritoneal dialysis has emerged as the first-choice dialysis modality in children awaiting for transplantation. Despite the improvements observed in catheter survival over the past several years, the obstruction is one of the reasons for immediate catheter non-function. This study assessed usefulness of ultrasound (US) in visualizing the obstruction of chronic peritoneal dialysis (CPD) catheter and identifying the etiology. MATERIALS AND METHODS: Between January 2000 and November 2012, 38 patients (20 M, 18 F) were treated with CPD and examined with US...

BACKGROUND: The greater omentum has been found to be immunologically competent in protecting abdominal organs from inflammation. Anastomotic omentoplasty has been used and proven effective in preventing anastomotic leaks after an esophagectomy. However, pulmonary complications are still a substantial problem after an esophagectomy. This study investigated the benefits of mediastinal transposition of the omentum, a modification of the conventional omental wrapping technique, in controlling overall postoperative intrathoracic complications...

OBJECTIVES: Artificial tracheas fabricated from collagen-conjugated mesh appear to overcome fatal postoperative complications, namely anastomotic dehiscence and prosthesis dislocation. Such prostheses are incorporated by host tissue, provided they are wrapped in omentum (necessitating an additional abdominal procedure) and a silicone tube is used as a stent (to be extracted several weeks postoperatively). To mitigate related host impact (i.e. injury, pain and distress), we investigated the feasibility of implanting this type of tracheal prosthesis (∼5 cm in length) alone, without omental wrapping and use of a silicone stent...

Successful performance of peritoneal dialysis (PD) depends on a properly functioning PD catheter. Catheter malfunction remains a significant cause of technique failure, especially early in the course of therapy. Common causes of catheter malfunction include catheter displacement, omental or bowel wrapping, and fibrin clots. Less commonly, various intraperitoneal structures have been reported to lead to obstruction, including appendices epiploicae of sigmoid colon and the fallopian tube. Peritoneal dialysis catheter blockage due to fimbriae of the fallopian tube is being recognized as an important cause of catheter malfunction in females due to the increasing availability of diagnostic laparoscopy...

Persistent pain after vaginal mesh surgery is a rare and agonizing entity that has devastating consequences for the patient's quality of life. Many etiologies have been blamed including nerve injuries and entrapments. Pudendal neuralgia is a rare chronic neuropathic pain syndrome in the anatomical territory of the pudendal nerve. Various treatment options, such as medication management, physiotherapy, nerve blocks, decompression surgery and neuromodulation, have been used, but the most appropriate treatment for pudendal neuralgia has not yet been determined...
