Anxiety, personality traits and quality of life in functional dyspepsia‐suffering patients

BACKGROUND Psychosocial stressors either acute or more sustained frequently precede the onset and exacerbation of the symptoms of the functional dyspepsia (FD). Depressive mood and quality of life have been already reported for interference in functional dyspepsia suffering patients. METHODS The examination were performed on 60 FD patients (30 females and 30 males), aged 20-79 years, 60 peptic ulcer subjects and 60 healthy volunteers in which we have investigate levels of anxiety and depression, personality traits and quality of life. RESULT According to the Hamilton Depression and Anxiety Rating Scales, the population with FD had the average score which classified them into the group of patients with the moderate depression (20.57 ± 4.45). Personality traits estimation based on data obtained by the Eysenck personality questionnaire revealed higher neuroticism scores in the group with functional dyspepsia. Both parameters, level of the neuroticism and anxiety level, expressed highly significant level of mutual concordance. Patients with functional dyspepsia reported a greater adverse impact of symptoms of emotional distress and food and drink problems. CONCLUSION Results are indicating that the depression and anxiety level is the highest in patients with functional dyspepsia and that anxiety level corroborates with the neuroticism level from the Eysenck scale. Psychological disturbances are influencing the quality of life mostly in patients with dyspepsia in the form of emotional distress and the problem with the food and beverage intake.

Lesion of the femoral nerve caused by a hydatid cyst of the right psoas muscle

INTRODUCTION Hydatidosis is a human disease caused by the larval form of Echinococcus granulosus. All organs in the human body may be affected by hydatid disease, but excluding liver and lungs, all other organs are considered as uncommon locations. Hydatid disease located in the psoas muscle is uncommon. CASE OUTLINE The authors present a 36-year-old male living in endemic areas of Serbia, admitted due to pain and weakness of the right thigh and weight loss. Duration of symptoms was one year. CT and MRI revealed a big cystic mass (20 cm long) in the right psoas muscle. Neurological investigation showed a loss of function of the right femoral nerve. Serology for Echinococcosis was negative. Surgery was indicated and performed by median laparotomy. Total excision of the cyst was done. Pathohystology confirmed the nature of the cyst. Three years after operation the patient was without any signs of disease relapse. CONCLUSION Echinococcal disease of the psoas has been very rarely reported, sometimes associated with paraspinal disease and often with vertebral involvement. Cystic or complex retroperitoneal tumour, pyogenic abscess of the psoas and even tuberculosis should be considered in the differential diagnosis. Treatment of choice is surgery. The greatest danger for the patient is dissemination and anaphylactic reaction. Also, compression of adjacent organs may produce significant morbidity.

Early Dumping Syndrome and Reflux Esophagitis Prevention with Pouch Reconstruction

BACKGROUND Total gastrectomy causes numerous disorders, such as reflux esophagitis, dumping syndrome, malabsorption, and malnutrition. To minimize the consequences, different variants of reconstruction are performed. The aim of our study is the comparison of two reconstructive methods: the standard Roux-en-Y and a new modality of pouch interposition, preduodenal-pouch interposition. This study aims to investigate the advantage of bile reflux prevention and to reduce symptoms of dumping syndrome after 3- and 6-mo follow-up. MATERIALS AND METHODS A total of 60 patients were divided in two groups: (A) 30 patients with Roux-en-Y reconstruction, and (B) 30 patients with the preduodenal-pouch (PDP) type of reconstruction. Endoscopic examination and endoluminal jejunal limb pressure measurements were performed. Scintigraphic measurements of half-emptying time were performed to evaluate meal elimination in the context of reflux esophagitis and early dumping syndrome. The Japan Society of Gastrointestinal Surgery has provided guidelines with which to classify the symptoms of early dumping syndrome. Patients were followed up for periods of 3 and 6 mo after the surgery. RESULTS Our study groups did not differ with regard to the level of reflux esophagitis (P = 0.688). Average values of pressure at 10 and 15 cm below the esophago-jejunal junction were significantly lower in the PDP group (P < 0.001). Elimination of the test meal between two groups was not significant (P = 0.222). Evaluation of early dumping syndrome symptoms revealed a significant reduction among PDP patients after 3 and 6 mo. CONCLUSION Our study showed significant superiority of the new pouch reconstruction over the standard Roux-en-Y approach in the treatment of early dumping syndrome.

Composite Carcinoma of the Stomach Associated with Sarcoid-Like Granulomas

Composite glandular/exocrine-endocrine carcinoma of the gastrointestinal tract is a special tumor type composed of common adenocarcinoma and the neuroendocrine component comprising at least one-third of the whole tumor area. These tumors are rare in the stomach and mostly published as case reports. We describe a further case of a 36-year-old man being unique in that it was associated with extensive formation of sarcoid-like granulomas. Tumor consisted of, predominantly poorly differentiated, intestinal-type adenocarcinoma and poorly differentiated neuroendocrine, small cell carcinoma. The adenocarcinomatous and neuroendocrine areas were separated, but closely juxtaposed with focal areas showing gradual transition from one to another. Perigastric lymph node metastases corresponded either to neuroendocrine or adenocarcinomatous component. On immunohistochemistry, the exocrine part was positive for cytokeratin 7, whereas superficial well-differentiated parts showed positivity with cytokeratin 20 as well. The neuroendocrine component was negative with those two types of cytokeratin. Both adenocarcinomatous and neuroendocrine tumor portions showed carcinoembryonic antigen (CEA) immunoexpression. Neuroendocrine markers (chromogranin A, synaptophysin and neuron-specific enolase) were diffusely positive in the neuroendocrine component, and found only in the scattered cells within the neoplastic glands of the adenocarcinoma. Entire gastric mucosa and all perigastric lymph nodes were extensively affected by noncaseating, sarcoid-like granulomas. The absence of any clinical manifestations combined with the negative results of chest radiograph and laboratory test for the serum angiotensin converting enzyme argued against the possibility of systemic sarcoidosis.

Common Variable Immunodeficiency Associated with Inflammatory Bowel Disease and Type I Diabetes

Common variable immunodeficiency (CVID) is a heterogeneous group of primary immunodeficiency disorders characterized by defective antibody production, low levels of serum immunoglobulins and increased susceptibility to infection. The patient was a 39-year-old male who was admitted to the gastroenterology department with a two week history of diarrhea, blunt abdominal pain below the umbilicus, prolonged febrile state, loss of appetite and loss of body weight of 18 kg during the previous six months. Screening tests of serum immunoglobulins showed decreased concentrations of three types of immunoglobulins: IgA < 0.24 g/L, IgM < 0.18 g/L and IgG < 1.55 g/L. Lymphocytes immunophenotypisation revealed inversed CD4+/8+ T cells ratio, 0.31 and absence of plasma cells (CD138 negative). Colonoscopy showed a rectal mucosa like cobblestones with multiple longitudinal and serpentinous ulceration, without involvement of other segments of the colon and the small intestine. Histopathology revealed aphtous ulcerative lesions, transmural inflammation with multiple lymphoid aggregates and benign lymphoid nodular hyperplasia of the small intestine. Plasma cells were absent from the lamina propria. Magnetic resonance imaging of a perianal fistula demonstrated a trans-sphicteric type. This case is specific because of the three illnesses associated and only one case of an association of diabetes mellitus type I and immunodeficiency reported thus far.

Efficient way in early detection of malignant skin tumors by applying epiluminescence microscopy in skin screening

Screening is the identification of a preclinical disease by a relatively simple test. It is usually regarded as public health policy that is applied to population. The aim is to identify disease not recognized by the health services and the term preclinical refers rather to such an unrecognized disease than to clinical detectability or recognition. The majority of pigmented lesions of the skin can be diagnosed on the basis of clinical criteria, although there is an astonishing number of discrete pigmented lesions where the difference between melanocytic and non-melanocytic, benign and malignant lesions, melanoma and non-melanoma, is very hard or almost impossible to detect by a simple examination with the naked eye. With the use of the computer system for melanomoscopy and melanomography, Mole Max II, with digital epiluminescence microscopy, it is possible to see and record the changes on the skin that are located in the surface layer of the skin, as well as the changes that appear more deeply under the surface, on the border between the epidermis and the dermis, the place where melanocytes are placed. With such examination it is possible to differentiate benign from malignant lesions in the very early stage of the development. An early recognition of malignant alterations on the skin increases the chances of cure and total recovery to over 90%.

Surgery indeed has an important role in long-term outcome in patients with pancreatic head cancer.

We read with interest the article by Petermann et al. [1] in the August 2013 issue of World Journal of Surgery. First of all, we would like to congratulate the authors for their very interesting article. In this retrospective study 101 pancreatic head resections due to pancreatic ductal adenocarcinoma were analyzed. The authors wanted to assess the impact of postoperative complications, stratified by severity, on long-term survival of patients after pancreatic head resection for ductal adenocarcinoma. However, we have several concerns about their conclusions. First, the authors concluded that surgery is not associated with severe postoperative complications. Surgery is the cornestone in the treatment of pancreatic cancer. Pancreaticoduodenectomy (PD) is the standard surgical treatment of pancreas head cancer. Using an optimal pancreatic reconstruction technique is thought to be a major prophylactic measure to minimize the risk of PD-related complications. Also, there are many possibilities of type of reconstruction as well as many possibilities for pancreaticojejunostomies (PJA): (1) layer with or without telescope, (2) layer, end-to-end, end-to-side, ‘‘duct to mucosa,’’ ‘‘Blumgart‘s’’ anastomosis, etc. [2]. Further, we don’t agree with authors’ conclusion that surgery is not associated with severe postoperative complications. They did not mention what kind of reconstructions were performed In accordance with this we could state following facts. Delayed gastric emptying (DGE) occurs dominantly after pylorus-preserving pancreaticoduodenectomy (PPPD) and remains a leading cause of PPPD postoperative complications. Delayed gastric emptying was probably exacerbated by some intra-abdominal complications, such as an anastomotic leak or an abscess. Problems could also be caused by the surgical procedure itself, namely injury to the nerve of Latarjet. In one study the incidence of DGE was significantly reduced in the pyloric ring resection group compared to controls, without an increase in dumping syndrome [3]. Most pancreatic fistulas (PF) can be managed nonoperatively, but a significant number of grade C PF do require reoperative surgical intervention. Risk factors for pancreatic fistula are well recognized and include a soft pancreatic parenchyma, small main pancreatic duct caliber, and a distal pancreatic resection (vs PD) [4]. Type of anastomosis is also very important regarding this problem. For example, there is a statistically significant decrease in fistula rate in the invagination group—PJA with invagination compared to other types of anastomoses [5]. Patients with postoperative hemorrhage often have underlying complications such as pancreatic fistula that require urgent surgical treatment. Pancreatic enzymes in combination with infection can cause erosion of the gastroduodenal artery or splenic artery stump, resulting in significant bleeding requiring immediate treatment. D.

Nutritional Insight into Preduodenal Pouch Reconstruction One Year after Total Gastrectomy

BACKGROUND Various types of reconstructions have been developed to improve the quality of life of patients following total gastrectomy. In addition, to ensure larger food-intake reservoirs and extend meal transit times, different types of pouch reconstructions have been developed and described. Our opinion is that the most important factor in providing better physiologic regulation of ingested food is restoration of the duodenal passage and enlargement of the gastric substituent. MATERIALS AND METHODS In the present study, we compared standard a Roux-en-Y reconstruction and a preduodenal pouch (PDP) reconstruction. We evaluated the quality of life (QoL) for 60 patients during the first postoperative year, comparing serum albumin, protein, hemoglobin, iron, body weight, body mass index, and QoL. QoL was defined according to Korenagas score scale, which has 14 questions, for better understanding of subjective patient perceptions of digestive function. RESULTS Our study population did not differ in iron and hemoglobin levels at a 1-y follow-up. The difference between total serum albumin level was significant in all observed patients in the follow-up period in favor of the PDP reconstruction group (P = 0.001). The PDP reconstruction group also had a significantly higher serum protein level after 12 mo. The higher score difference between the two groups generally confirm the improved QoL in the PDP group (P = 0.001). CONCLUSION The most important aspects of improved QoL after gastrectomy due to gastric carcinoma are maintenance of the duodenal transit and the addition of a pouch. Jejunal preduodenal pouches provide a better QoL than Roux-en-Y reconstruction. Our study results suggest preduodenal pouch reconstruction should be used as the method of choice.

Obstructive jaundice and cholangitis caused by an arterial ring of the proper hepatic artery around the common bile duct

Summary Background Many different benign and malignant diseases can cause obstruction of the extrahepatic biliary duct. One of the more serious complications of biliary obstruction is cholangitis leading to emergency decompression. Anatomic variations are frequent in this region; however, it has rarely been reported that the extrahepatic bile duct is compressed by the arterial vessels. Case Report We present the case of a 68-year-old woman who was admitted through the emergency department of our hospital with jaundice, abdominal pain and fever. Biochemical analyses of liver function showed increased value of AST (113 IU/L) and AST (128 IU/L). Total bilirubin was 5.88 mg/dl, conjugated bilirubin was 3.00 mg/dl, and alkaline phosphatase was 393 IU/L. We performed abdominal ultrasound (US), magnetic resonance cholangiopancreatography (MRCP), and computed tomography (CT) imaging. Multislice CT angiography showed that the arterial ring of the common hepatic artery around the common bile duct (CBD) originated from the superior mesenteric artery. Cholecystectomy and intraoperative cholangiography were performed, as well as decompression and lavage of the biliary tree. Escherichia coli was identified from bile. Dissection of the hepatoduodenal ligament confirmed that the proper hepatic artery made a vascular ring around the CBD. Finally, a T tube was placed into the CBD. During 5 years of follow-up the patient has been without recurrent episodes of jaundice. In such cases dissection of the proper hepatic artery from the common hepatic duct is the treatment of choice. Conclusions If there are signs of cholangitis decompression and lavage of the biliary tree with “T”, drainage should be performed. Vascular malformations should be considered as a possible cause of extrahepatic biliary obstruction. CT angiography may be helpful in identifying these malformations.

Letter to the Editor: Stenting in Palliation of Unresectable Esophageal Cancer

Dear Editor, We read with great care and interest the article on stenting in palliation of unresectable esophageal cancer by Wlodarczyk and Kuzdzal [1] in the June 2018 issue of World Journal of Surgery. First of all, we wish to congratulate the authors on this scientific report and on their dedication to better understanding of this very significant disease and its treatment modalities, especially in the cases of advanced stages. This was a retrospective study with prospective data collection, which included 442 patients who underwent esophageal stenting procedure. The authors wanted to evaluate the safety and efficacy of stenting in patients with esophageal squamous cell carcinoma and carcinoma of the esophagogastric junction, complications, re-interventions and survival after the treatment. Our concerns are in regards to the exact stage of the esophageal cancer and its possible resectability. According to Ajani et al. [2], patients with esophageal cancer can be divided into two groups: locoregional cancer (stages I–III) and metastatic cancer (stage IV). Patients with locoregional cancer must be treated surgically, unless there are severe comorbidities that present major risk factors for complications and mortality of anesthesia and surgery. We think that it would have been very useful if Wlodarczyk and Kuzdzal had stated in their study the exact cancer stage of the patients that underwent palliative esophageal stenting. In their study on 2626 patients over the age of 65 (Surveillance, Epidemiology, and End Results—SEER), Smith et al. [3] showed that in patients with advanced locoregional disease (T3-T4aN0 or T1-4aN1), the best results are obtained combining preoperative chemotherapy and surgery. Thus, we think that it would be very interesting if the authors stated the exact stage and what were the main criteria for non-resectability. According to European Society of Gastrointestinal Endoscopy (ESGE) clinical guidelines [4], brachytherapy can be used in addition to palliative stenting in esophageal cancer patients. Brachytherapy may provide better quality of life and survival rate [4]. We feel that additional data on brachytherapy, if it was considered as a therapeutic modality at all in the study by Wlodarczyk and Kuzdzal, could give useful guidelines in treating patients with advanced esophageal cancer. Wlodarczyk and Kuzdzal stated that they performed double stenting (synchronous stenting of airway and esophagus) in patients with unresectable esophageal cancer that had involved airway. Shin et al. [5], in their study on 61 patients with esophagorespiratory fistulas, placed with success SEMS in 51 patients, while only 10 patients needed double stenting. They managed to seal off the fistula in 49 patients, while only 10 (16%) needed a concomitant airway stent. According to clinical guidelines [4], esophageal stenting is recommended as the best treatment for sealing esophagorespiratory fistulas (tracheoesophageal or bronchoesophageal). Also, application of double stenting can be considered in cases when fistula occlusion is not accomplished by esophageal stenting alone [4]. We hope that these additional data would give more accurate directives in treating patients with advanced-stage esophageal cancer, in order to define the best approach and therapeutic strategy. & Vladimir Resanovic vladaresan@gmail.com
