Nutritional Management of Esophageal Cancer Patients

Esophageal cancer is associated with malnutrition in the vast majority of patients. This phenomenon is partly attributed to the disease process itself, the location of the tumor and other factors, such as dysphagia which is often accentuated due to chemotherapy/radiotherapy treatment or surgical intervention. The poor nutritional status of these patients is often related to the presence of cancer cachexia, altered metabolism, and tissue wasting. Malnutrition in this patient population affects quality of life, worsens patient’s tolerance to chemotherapy and accounts for lower survival. Nutritional management of these patients includes both proper nutritional assessment and support and might prevent, to a certain extent, the manifestation of malnutrition‐related consequences. The purpose of this article is to review the current literature in order to focus on the etiology and diagnosis of malnutrition in esophageal cancer patients, emphasizing also on the optimal nutritional support during multimodality treatment

Ablation of the locally advanced pancreatic cancer: An introduction and brief summary of techniques

Pancreatic ductal adenocarcinoma is a lethal and late presenting malignancy with dismal survival rates. An estimated total of 330,000 people died from this malignancy in 2012. Although there have been improvements in diagnostic and treatment methods, the survival of late stage pancreatic cancer has not shown significant improvement in the past 4 decades. Multiple treatment approaches are available including chemotherapy, radiotherapy, and immunotherapy, but to this day surgical resection remains the only curative treatment option. Ablative techniques use various forms of energy to cause local tissue destruction through necrosis or apoptosis. They are relevant in pancreatic ductal adenocarcinoma as they are a treatment option in non-resectable tumors where their use ranges from symptom control to reducing tumor size for resection. In this narrative review we have grouped and outlined the various ablative methods, classifying them into thermal (Radiofrequency ablation, Microwave ablation, High Intensity Focused Ultrasound ablation, Cryoablation), and non-thermal ablative methods (Irreversible Electroporation (NanoKnife®), Photodynamic Therapy). This is followed by a description and review of the available evidence on survival and complications for each of these ablative methods. According to the literature, thermal ablative methods appear to be more accessible but are implicated with more complications than non thermal ablative methods which show the most promise

Irreversible electroporation (Nanoknife® treatment) in the field of hepatobiliary surgery: current status and future perspectives

Purpose: We aimed to provide an overview of current understanding on the potential use of irreversible electroporation (IRE) in the field of hepatobiliary surgery with a focus on current results in hepatic and pancreatic cancers, its limitations, and its current directions. Methods: Through a review of the literature we have gathered the key articles and trials that are shaping our understanding of the current status of IRE and its prospective uses, and organized them in an easily understandable format showcasing the most up to date results. Results: IRE appears to be comparable in effectiveness and postoperative pain to the more established thermal ablation methods, while having the benefit of avoiding their detrimental thermal effects. In liver cancer, IRE was shown to be efficacious with low levels of local recurrences and only minimal complications. In pancreatic cancer it proved to have significant survival benefits but more significant (although rare) complications compared to the ones seen when IRE is used in liver cancer. Current evidence suggests a promising future for IRE, but clinical randomized control trials, and further developments of treatment protocols are required to come to more stable conclusions on the effectiveness and safety of IRE. Conclusions: IRE is proving to be an adequate method for the treatment of tumors of the pancreas and liver in cases where traditional methods are unavailable. It has been proven particularly efficacious in patients with masses in close proximity to vital structures such as vessels, as well as major biliary and hepatic structures where thermal methods of ablation would cause significant complications

Early or Delayed Intervention for Bile Duct Injuries following Laparoscopic Cholecystectomy? A Dilemma Looking for an Answer

Background. To evaluate the effect of timing of management and intervention on outcomes of bile duct injury. Materials and Methods. We retrospectively analyzed 92 patients between 1991 and 2011. Data concerned patient’s demographic characteristics, type of injury (according to Strasberg classification), time to referral, diagnostic procedures, timing of surgical management, and final outcome. The endpoint was the comparison of postoperative morbidity (stricture, recurrent cholangitis, required interventions/dilations, and redo reconstruction) and mortality between early (less than 2 weeks) and late (over 12 weeks) surgical reconstruction. Results. Three patients were treated conservatively, two patients were treated with percutaneous drainage, and 13 patients underwent PTC or ERCP. In total 74 patients were operated on in our unit. 58 of them underwent surgical reconstruction by end-to-side Roux-en-Y hepaticojejunostomy, 11 underwent primary bile duct repair, and the remaining 5 underwent more complex procedures. Of the 56 patients, 34 patients were submitted to early reconstruction, while 22 patients were submitted to late reconstruction. After a median follow-up of 93 months, there were two deaths associated with BDI after LC. Outcomes after early repairs were equal to outcomes after late repairs when performed by specialists. Conclusions. Early repair after BDI results in equal outcomes compared with late repair. BDI patients should be referred to centers of expertise and experience

Rapunzel Syndrome: A Rare Presentation with Giant Gastric Ulcer

The Rapunzel syndrome refers to an uncommon and rare form of trichobezoar that extends past the stomach into the small intestines. The Rapunzel syndrome is usually found in young female patients with a history of psychiatric disorders, mainly trichotillomania and trichophagia. We describe a case of Rapunzel syndrome in a 15-year-old girl who presented with abdominal pain, vomiting, and weight loss. We performed a surgical laparotomy and successfully removed a huge trichobezoar extending into the small intestine

The Role of Endoscopic Ultrasound in the Diagnosis and Management of Primary Gastric Lymphoma

Endoscopic ultrasound (EUS) is considered a valuable diagnostic tool during the workup of malignant gastric lesions, including primary gastric lymphomas (PGL). Although endoscopy combined with multiple biopsies remains essential in the establishment of PGL diagnosis, EUS utilization in locoregional disease staging has been well documented in the literature. Data also support the possible role of EUS in prediction of response to first-line treatment, that is, Helicobacter pylori eradication. However, its application in the posttreatment setting remains problematic, since concordance rates between endosonography and histology findings during follow-up seem to vary substantially. The aim of the present review is to summarize all available data regarding the role of EUS in the management of PGL

A pathological fracture and a solitary mass in the right clavicle: an unusual first presentation of HCC and the role of immunohistochemistry

<p>Absrtract</p> <p>Hepatocellular carcinoma (HCC) is an aggressive malignant tumor that occurs throughout the world. Μetastases from hepatocellular carcinoma (HCC) were generally considered to be rare in the past, because the carcinoma had an aggressive clinical course. In our era, has been reported that extra-hepatic metastases occur in 13.5%-41.7% of HCC patients and this is considered as terminal-stage cancer. The prognosis for patients at this stage continues to be poor due to limited effective treatment. The common sites of extrahepatic metastases in patients with HCC are the lungs, regional lymph nodes, kidney, bone marrow and adrenals. We present here an extremely infrequent case of a patient, without known liver disease, in which the presenting symptom was a pathological-in retrospect-fracture of his right clavicle which wasn't properly evaluated, until he presented a bulky mass in the region 6 months later. For our patient, the added diagnostic difficulty alongside the unknown liver disease, has been that the clavicular metastases was the first presentation of any metastatic disease, rather than the more common sites of HCC spread to adjacent lung or lymph nodes.</p
