The synchronous occurrence of GISTs and other gastrointestinal malignancies is more common than it has been considered. The development of gastrointestinal stromal tumors and other neoplasms may involve the same carcinogenic agents.
IntroductionMesenteric fibromatosis or intra-abdominal desmoid tumour is a rare proliferative disease affecting the mesentery. It is a locally aggressive tumour that lacks metastatic potential, but the local recurrence is common. Mesenteric fibromatosis with the intestinal involvement can be easily confused with other primary gastrointestinal tumours, especially with that of the mesenchymal origin.Case reportWe report a case of a 44-year-old female who presented with an abdominal mass that radiologically and pathologically mimicked a gastrointestinal stromal tumour.ConclusionsThe diagnosis of mesenteric fibromatosis should always be considered in the case of mesenchymal tumours apparently originating from the bowel wall that diffusely infiltrate the mesentery.
BackgroundThe role of percutaneous drainage in the management of infected pancreatic necrosis remains controversial, and ultrasound-guided technique is rarely used for this indication. The purpose of this study was to evaluate the safety and efficacy of sonographically guided percutaneous catheter drainage for infected pancreatic necrosis.MethodsThe patient group consisted of 16 men and 2 women. The mean age of the patients was 47 years. The median computed tomography severity index of acute pancreatitis was 10 points. Percutaneous catheter drainage was performed under sonographic guidance using preferably retroperitoneal approach, and transperitoneal access in selected cases. The medical records and imaging scans were reviewed retrospectively for each patient.ResultsPercutaneous catheter drainage resulted in a complete resolution of infected pancreatic necrosis in 6 of 18 patients (33 %). Twelve of 18 patients who were initially managed with PCD required eventually necrosectomy (67 %). The most common reason for crossover to surgical intervention was persistent sepsis (n = 7). Open necrosectomy was performed in 4 of these patients, and 3 patients underwent successful minimally invasive retroperitoneal necrosectomy. Five patients required conversion to open surgery because of procedure-related complications. In 3 cases, there was leakage of the necrotic material into the peritoneal cavity. Two other patients experienced hemorrhagic complications. Overall mortality rate was 17 %. The size of the largest necrotic collection in patients who were successfully treated with percutaneous drainage decreased by a median of 76 % shortly after the procedure, whereas it decreased only by a median of 16 % in cases of failure of percutaneous drainage.ConclusionsUltrasound-guided percutaneous catheter drainage used in infected pancreatic necrosis is a technique with acceptably low morbidity and mortality that may be the definitive treatment or a bridge management to necrosectomy. A negligible decrease in size of the necrotic collection predicts failure of percutaneous drainage.
Necrotizing fasciitis is a rare, but potentially fatal bacterial infection of the soft tissues. Establishing the diagnosis at the early stages of the disease remains the greatest challenge. We report a case ofnecrotizing fasciitis involving the upper extremity. Sonography revealed subcutaneous emphysema spreading along the deep fascia, swelling, and increased echogenicity of the overlying fatty tissue with interlacing fluid collections. The patient responded well to early surgical debridement and parenteral antibiotics. © 2010 Wiley Periodicals, Inc. J Clin Ultrasound, 2011
Background: Surgical management of severe pancreatic fistula after pancreatoduodenectomy remains challenging, and carries high mortality. The aim of this retrospective study was to compare different surgical techniques used at relaparotomy for pancreatic fistula after pancreatoduodenectomy, and to identify factors predictive of failure to rescue.Methods: A total of 43 patients after pancreatoduodenectomy developed a pancreatic fistula requiring relaparotomy. The perioperative data and outcomes were reviewed retrospectively.Results: Completion pancreatectomy, simple drainage of the pancreatic anastomosis and external wirsungostomy were performed in 17, 16, and 10 cases, respectively. The mortality rate for completion pancreatectomy was 47.1%, compared with 56.3% for simple drainage (p = 0.598) and 50.0% for external wirsungostomy (p = 0.883). Simple drainage was associated with a higher rate of further relaparotomies (56.3%) in comparison with completion pancreatectomy (23.5%, p = 0.055) and external wirsungostomy (0%, p = 0.003). A rescue resection of the pancreatic remnant after failed simple drainage resulted invariably in death. On multivariate analysis, the factors predictive of mortality after relaparotomy for pancreatic fistula were organ failure on the day of reoperation (p = 0.001) and need of further surgical reintervention (p = 0.007). Conclusion: Timely reintervention and appropriate surgical technique are essential for reducing mortality after reoperation for pancreatic fistula after pancreatoduodenectomy.
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.
