    New Data on Pancreatic Cancer In pancreatic cancer there is a marked discrepancy between the recorded R0 resection rates and the long-term clinical outcome. Therefore, it seems to be necessary to find additional parameters that will be of more prognostic value here. Differences in how the R classification is applied within the studies are conspicuous. It would seem important to examine standards in histopathological preparation and to return to the `classical' R classification and, if appropriate, in line with experiences in rectum cancer, to introduce a `circumferential resection margin'. To obtain optimum long-term survival, a distance of >1.0 mm or even >1.5 mm between tumor and resection margin is required. In too few patients with vascular invasion is the tumor properly removed surgically, even though infiltration of the portal vein or the superior mesenteric vein is not an exclusion criterion according to the S3 guideline. An improvement in the quality of treatment might be achieved by establishing `high-volume' pancreas centers. The value of perioperative radiochemotherapy (RCT) is currently being examined in several large studies. Adjuvant chemotherapy is standard and is well established in routine clinical practice

    Leiomyosarcoma of the inferior vena cava: Radical surgery and vascular reconstruction

    <p>Abstract</p> <p>Background</p> <p>Vascular leiomyosarcoma are rare tumors typically originating from the inferior vena cava (IVC). Due to nonspecific clinical signs most tumors are diagnosed at advanced stages. Complete surgical resection remains the only potential curative therapeutic option. Surgical strategy is particularly influenced by the level of the IVC affected. Due to the topographic relation to the renal veins level-II involvement of the IVC raises special surgical challenges with respect to the maintenance of venous outflow.</p> <p>Case presentation</p> <p>We herein report two cases of leiomyosarcoma of the IVC with successful en bloc resection and individualized caval reconstruction. One patient presented with a large intramural and intraluminal mass and received a complete circumferential resection. Reconstruction was performed by graft replacement of the caval segment affected. The other patient displayed a predominantly extraluminal tumor growth and underwent semicircumferential resection of the IVC including the confluence of the left renal vein. In this case vascular reconstruction was performed by cavoplasty and reinsertion of the left renal vein into the proximal portion of the IVC. Resection margins of both patients were tumor free and no clinical signs of venous insufficiency of the lower extremity occurred.</p> <p>Conclusion</p> <p>This paper presents two cases of successfully managed leiomyosarcomas of the vena cava and exemplifies two different options for vascular reconstruction in level II sarcomas and includes a thorough review of the literature.</p

    Recurrent Fistula between Ileal Pouch and Vagina—Successful Treatment with a Gracilis Muscle Flap

    Fistulae between an ileal pouch and the vagina are an uncommon complication of ileal pouch-anal anastomosis following proctocolectomy and mucosectomy in patients with familial adenomatous polyposis coli. Several reports describe the successful use of muscle flaps to close recurrent pouch-vaginal-fistulae (PVF). However, series only contain small numbers and an optimal management has not yet been determined. We report the case of a 26-year old woman with a third recurrence of a PVF after proctocolectomy for treatment of familial adenomatous polyposis in October 2005. Because local approaches failed, definitive closure of the fistula was achieved by interposition of a gracilis muscle flap between the pouch-anal anastomosis and the vagina. The postoperative course was uneventful; the patient was discharged 7 days after surgery and remained free of recurrence and symptomatic complaints for 22 months now. The gracilis muscle flap proved to be an effective method in the treatment of recurrent PVF

    Is Aggressive Surgical Palliation of Proximal Bile Duct Cancer With Involvement of Both Main Hepatic Ducts Worthwhile?

    The only curative treatment for proximal bile duct cancer with involvement of both main hepatic ducts is liver transplantation. Most patients do not fulfill the requirements for liver transplantation. Our treatment strategy in appropriate cases is palliative tumor resection and reconstruction of the biliary passage by sutureless bilioenteric anastomosis. We have treated 12 patients, 5 in combination with intraluminal and percutaneous radiotherapy. Our results indicate that this strategy leads to effective palliation in some cases provided that only microscopic residual tumor is left in-situ. Our survival times compare favourably with survival after liver transplantation

    <p>Abstract</p> <p>Background</p> <p>Malignant esophageal stenosis with complete obstruction and esophagorespiratory fistula (ERF) is difficult to treat with standard endoscopic techniques.</p> <p>Case presentation</p> <p>We report a patient in whom with local recurrence of esophageal carcinoma an esophagotracheal fistula occurred. Initially the patient had undergone esophageal resection with interposition of a gastric tube. Due to complete obstruction of the lumen by recurrent tumor conventional transoral stent placement failed. For retrograde dilatation a laparotomy was performed. Via a duodenal incision endoscopic access to the gastric tube was achieved. Using a guidewire the esophageal obstruction was traversed and dilated. Then it was possible to place an esophageal stent via an antegrade approach.</p> <p>Conclusion</p> <p>Open surgery enables a safe access for retrograde endoscopic therapy in patients who had undergone esophageal resection with gastric interposition.</p

    Combined esophageal injury complicated by progression to a second perforation: a case report

    <p>Abstract</p> <p>Introduction</p> <p>Intramural dissection of the esophagus is a rare disorder characterized by a lesion between the submucosa and mucosa dividing the esophagus into a false and true lumen. The etiology of esophageal dissection remains uncertain but it affects predominantly women in their seventies and eighties. Symptoms may include uncharacteristic ones such as retrosternal pain, odynophagia or dysphagia. Conservative management is thought to be adequate and surgery should only be performed if complications such as abscess formation or perforation appear. Here we report the case and surgical management of a combined esophageal perforation and dissection.</p> <p>Case presentation</p> <p>We report the case of a combined esophageal perforation and dissection in a 45-year-old Caucasian woman with a history of relapsing periods of dysphagia since her childhood. The clinical course in this patient was complicated by progression to a second perforation, which made a definitive surgical management by esophagectomy necessary.</p> <p>Conclusion</p> <p>To the best of our knowledge, this is the first reported case of a combined esophageal perforation and dissection complicated by progression to a second perforation. This emphasizes that cautious and intensive observation is necessary in patients with esophageal dissection.</p

    Leser-Trélat sign presenting in a patient with ovarian cancer: a case report

    <p>Abstract</p> <p>Introduction</p> <p>Seborrheic keratoses are very common findings in elderly patients. However, a sudden onset and dramatic increase in the number and size of these benign lesions deserves special attention, since this may represent the Leser Trélat sign, a rare paraneoplastic cutaneous syndrome.</p> <p>Case presentation</p> <p>A 92-year-old female presented to our clinic with multiple eruptive seborrheic keratoses, which had dramatically increased in size and number over the past two years. A diagnostic work-up revealed an ovarian carcinoma. Hence, cutaneous findings in our patient were consistent with the diagnosis of the Leser-Trélat sign.</p> <p>Conclusion</p> <p>The Leser-Trélat sign may coincide with the diagnosis of occult cancer or follow or precede it by months or years. Practitioners should take cases of eruptive seborrheic keratoses seriously and perform thorough patient examinations.</p
