    Results of surgical treatment of 69 patients with injuries of the duodenum were analyzed. The most frequent causes of the injury were stab-incised wound of the abdomen (43 patients), gunshot wounds (2 patients), closed injury of the abdomen. Postoperative complications developed in 18 (26%) cases. Lethality was 20.3% (14 patients died). Injuries caused by the closed trauma were considerably more severe than those caused by wounds of the duodenum; lethality was 37.5% and 11.1% respectively. The authors discuss questions of the special diagnostics and surgical strategy for open and closed injuries of the duodenum. Causes of the development of unfavorable outcomes were pyo-septic complications associated with progressing retroperitoneal phlegmons, peritonitis, development of traumatic pancreatitis, incompetent sutures of the duodenum with a formed duodenal fistula. Therefore, the effective prophylactics of incompetent sutures of the duodenum is its decompression with aspiration of the duodenal contents as well as decreased secretion by means of drainage of the bile excreting ducts and medicamental suppression of synthesis of the digestion enzymes of the pancreas and duodenum using Octreatid which allowed considerable decrease of the number of postoperative complications.

  2. The stomach and duodenum

    Symptoms of epigastric pain raise the possibility of peptic ulcer disease and lead to an examination of the stomach and duodenum. Hematemesis or melena is also a strong indication. The nausea-vomiting complex on a subacute or chronic basis raises the possibility of an obstructive lesion. A palpable mass in the upper abdomen may involve the stomach. Weight loss and anorexia are less specific symptoms but can occur with gastric cancer. Major changes in indications have occurred now that ultrasonography, computed tomography (CT), and magnetic resonance (MR) imaging are available. No longer is the gut studied to detect extra-gut disease. Currently, the duodenal contour is not important in the search for pancreatic disease. All intra-abdominal structures can now be seen directly using CT or ultrasound

    Primary carcinoma of the duodenum represents about 0.35% of all gastrointestinal carcinomas and is thus a rare disease. The radiological diagnosis of a duodenal origin is made more difficult by the close proximity of the pancreas, biliary system, right kidney and transverse colon. Histologically, duodenal malignant tumours are usually adenocarcinomas. Between 1973 and 1983, eight patients with primary duodenal carcinomas were diagnosed at the University of Tuebingen. Average age of the patients was 67 years. There was no sex difference. Average survival was 3.3 years. (orig.) [de

    2008-01-01

    A number of imaging techniques, many of them complementary, are used in the investigation and treatment of disorders of the stomach and duodenum. Optimal patient treatment requires a thorough knowledge of the application of these techniques, as well as a sound understanding of pathology of the stomach and its presenting symptomatology. This well-illustrated book covers the various investigative methods in detail, discussing their advantages and disadvantages and explaining their role in specific settings. It will be of great value to both trainee and experienced radiologists, and should assist in promoting effective and judicious patient management. (orig.)

    Recurrent gastrointestinal bleeding from hepatocellular carcinoma (HCC) invading the duodenum is very rare. We present a case of 50-year-old male who was admitted with a history of recurrent upper gastrointestinal tract (UGIT) bleeding, weight loss and anemia. The patient was known to have a chronic hepatitis C. Endoscopic examination showed grade-2 non-bleeding esophageal varices, and a large ulcerated duodenal mass partially obstructing the duodenal bulb outlet and causing recurrent UGIT bleeding. Pathological evaluation of the mass revealed HCC. (author)

  9. Bouveret syndrome: gallstone ileus of the duodenum.

    2012-10-01

    This is a case of a 59-year-old woman with Bouveret syndrome. An initial endoscopic approach to management is described. Gallstone ileus occurs when a gallstone passes from a cholecystoduodenal fistula or a choledochoduodenal fistula into the gastrointestinal tract and causes obstruction, usually at the ileocecal valve. Bouveret syndrome is a variant of gallstone ileus where the gallstone lodges in the duodenum or pylorus causing a gastric outlet obstruction. The endoscopic and surgical management of this process are important to keep in mind and may be evolving as endoscopic therapies improve.

  10. Modified X-ray method of a study of duodenum

    A modified X-ray examination of duodenum under hypotension conditions is described. In comparison with the existing method, the above-mentioned modification allows one to investigate the duodenum by using double contrast - the high-concentrated barium suspension and the gas, formed after the gasificated powder dose. 327 patients have been examined by the given method, 126 of them have been diagnosed to suffer from inflammatory diseases of the stomach and the duodenum, 22 of them suffering from the duodenum peptic ulcer, 107 of them - pancreatitis, 48-cholelithiasis, 24 - the tumor of the pancreatoduodenum zone. 65 patients have been operated on. Roentgenomorphologic comparisons have been carried out for 66 patients suffering from inflammatory deseases of the duodenum. Duodenum visualization of 283 patients is found to be good and satisfactory. The given method may be used under any conditions, including polyclinics, due to the sparing nature.

    Celiac disease (CD) is the most common form of malabsorption in childhood when it presents with diarrhea and groeth failure, a jejunal biopsy is considered the first diagnostic investigation by some authors. In adulthood, clinical symptoms of CD may mimik several different disease, such as peptic ulcer and IBS, and the first diagnostic investigation is an upper GI series. Radiological features of duodenum and small bowel were evaluated in twenty patients with adult onset celiac disease. Sign of duodenitis such as thickened folds, mucosal nodules, dilatation of duodenum and erosions were observed in 19 out of 20 patients (95%); particulary, thickened folds in 71 (85%), nodularity in 16 (80%), duodenal dilatation in 12 (60%) and erosions in 4 (20%). In celiac disease the lesions are more severe in the upper part of small bowel, and duodenitis may be the unique sign of CD. Duodenitis may be part of a disease involving the entire small bowel; so, a duodenitis observed in the upper gastrointestinal tract requires the study of the entire small bowel - which seems to be very important in the case of celiac disease

    1988-01-01

    Blunt trauma to the epigastrium is becoming an increasingly important cause of injury and may result in retroperitoneal haematoma invoving the head of the pancreas as well as the descending duodenum. Ultrasound seems to be of great advantage in the diagnosis of the effects and complications of blunt abdominal trauma such as obstruction of the bilary tree, the gastric outlet and the inferior vena cava. Direct involvement of the descending duodenum seems to be relatively uncommon, intramural haematoma of the duodenum is described only rarely in the literature. Three additional cases of intramural haematoma of the duodenum are reported with particular reference to the recent literature. (orig.) [de

    2014-05-11

    Complete transverse rupture of the duodenum as an isolated lesion in blunt trauma can be considered as exceptional. The aim of this report is to discuss diagnostic procedures and surgical options in such an infrequent presentation. We report on a 37 year old man who had a total transverse rupture of the duodenum after blunt abdominal trauma. Diagnosis was suspected after contrast enhanced CT scan and confirmed at laparotomy; duodenal rupture was repaired by an end to end duodenal-duodenal anastomosis, after Kocher maneuver. The patient had fast and complete recovery. A high index of suspicion is necessary for timely diagnosis. Multi detector contrast enhanced CT scan is the gold standard for that aim. Surgical management must be tailored on an individual basis, since many techniques are available for both reconstruction and duodenum decompression. Kocher maneuver is essential for complete inspection of the pancreatic duodenal block and for appropriate reconstruction. Management of isolated duodenal rupture can be difficult. Contrast enhanced TC scans is essential for timely diagnosis. Primary repair can be achieved by an end to end duodenum anastomosis after Kocher maneuver, although alternative techniques are available for tailored solutions. Complex duodenum decompression techniques are not mandatory.

    We report a case of abdominal injury secondary to child abuse in which the child had both a duodenal hematoma and contained perforations of the duodenum and proximal jejunum. These injuries were evaluated by both CT scan and upper gastrointestinal (GI) series. The child's nausea and vomiting persisted despite conservative treatment; after 3 weeks a repeat upper GI series demonstrated high-grade duodenal obstruction. An exploratory laparotomy was performed and a calcified, fibrotic mesentery and strictures in the distal duodenum and proximal jejunum were found. To our knowledge, his unusual complication of blunt abdominal trauma has not been described in association with child abuse. (orig.)

    Full Text Available Gangliocytic paragangliomas are infrequent tumors almost exclusively found in the second portion of the duodenum. An unusual case of a gangliocytic paraganglioma in the third portion of the duodenum with obstructive symptoms is herein reported. A 16-year-old male patient presented with epigastric pain, postprandial plenitude and reflux. A barium swallow failed to demonstrate abnormalities. Endoscopy showed a pedunculated submucosal tumor, originating at the third duodenal portion and causing partial obstruction. Biopsy was not performed due to the risk of bleeding. CT scan demonstrated a polypoid lesion. Through a transmesocolic approach and an anterior duodenotomy, resection of the tumor was performed. No lymph node or other organ affection was found. Histologic examination revealed a gangliocytic paraganglioma. Immunohistochemical examination was performed. Gangliocytic paragangliomas originating in the third or fourth portion of the duodenum, as in the present case, are extremely rare. Characteristic histologic features including epithelioid cells, spindle-shaped cells and ganglion-like cells were met. The majority of cases manifest with a similar benign behavior. Local resection of the tumor is recommended for these cases. An infrequent case of a gangliocytic paraganglioma located in the third portion of the duodenum, with a less common clinical presentation, is herein reported.

    1979-10-01

    The influence of severe exocrine pancreatic disease on the acid-neutralizing capacity of the duodenum was studied in five patients with pancreatic insufficiency (PI) and six control subjects using duodenal perfusion-marker technique. Hydrochloric acid (0.1 N containing 1% PEG) was infused at constant rates (1.2, 4.5 and 7.0 ml/min) into the duodenum just distal to the duodenal bulb. Samples were aspirated from the tip of the duodenal perfusion tube located at the ligament of Treitz. All samples were analyzed for volume, pH, titrable acidity, PEG and [14C]PEG (gastric marker) determination. Patients with PI demonstrated significantly diminished ability to neutralize various acid loads as compared to controls who virtually completely neutralized acid loads in the range of maximal gastric acid secretion. Exogenous secretin did not significantly improve percent acid neutralized in PI. These data clearly indicate that patients with PI have significantly impaired ability to neutralize even small loads of acid in the duodenum.

    A case of duodenal rupture with a roll three-point seatbelt is described. It is apparently the seventh reported case of duodenal rupture in safety belt users. A female driver fell asleep, and her car went off the road, rolling forward in a ditch, slowing slightly, and then came to a sudden stop. The rupture was unusual: on the first part of duodenum, intraperitoneal, and longitudinal. The rupture mechanism is discussed, and the deficiencies of the roll seatbelt pointed out in accidents like the one described.

    Gangliocytic paragangliomas are rare tumors that almost exclusively occur within the second portion of the duodenum. Although these tumors generally have a benign clinical course, they have the potential to recur or metastasize to regional lymph nodes. The case report presented here describes a 57-year-old female patient with melena, progressive asthenia, anemia, and a mass in the second-third portion of the duodenum that was treated by local excision. The patient was diagnosed with a friable bleeding tumor. The histologic analysis showed that the tumor was a 4 cm gangliocytic paraganglioma without a malignant cell pattern. In the absence of local invasion or distant metastasis, endoscopic resection represents a feasible, curative therapy. Although endoscopic polypectomy is currently considered the treatment of choice, it is not recommended if the size of the tumor is > 3 cm and/or there is active or recent bleeding. Patients diagnosed with a gangliocytic paraganglioma should be closely followed-up for possible local recurrence.

    This single-centre study evaluated the outcome of a pancreatoduodenectomy for Grade 5 injuries of the pancreas and duodenum. Prospectively recorded data of patients who underwent a pancreatoduodenectomy for trauma at a Level I Trauma Centre during a 22-year period were analysed. Nineteen (17 men and 2 women, median age 28 years, range 14-53 years) out of 426 patients with pancreatic injuries underwent a pancreatoduodenectomy (gunshot n = 12, blunt trauma n = 6 and stab wound n = 1). Nine patients had associated inferior vena cava (IVC) or portal vein (PV) injuries. Five patients had initial damage control procedures and underwent a definitive operation at a median of 15 h (range 11-92) later. Twelve had a pylorus-preserving pancreatoduodenectomy (PPPD) and 7 a standard Whipple. Three patients with APACHE II scores of 15, 18, 18 died post-operatively of multi-organ failure. All 16 survivors had Dindo-Clavien grade I (n = 1), grade II (n = 7), grade IIIa (n = 2), grade IVa (n = 6) post-operative complications. Factors complicating surgery were shock on admission, number of associated injuries, coagulopathy, hypothermia, gross bowel oedema and traumatic pancreatitis. A pancreatoduodenectomy is a life-saving procedure in a small cohort of stable patients with non-reconstructable pancreatic head injuries. Damage control before a pancreatoduodenectomy will salvage a proportion of the most severely injured patients who have multiple injuries. © 2014 International Hepato-Pancreato-Biliary Association.

    The incidence of duodenal diverticulum found incidentally during upper gastrointestinal roentgenographic examination varies between 2% and 5%. The majority of cases occur along the medial aspect of the second portion of the duodenum, within 2.5 cm of the ampulla of Vater. The majority of duodenal diverticual are asymptomatic, but in some cases, complications such as diverticulitis, hemorrhage, perforation, and fistula formation occur in the third and fourth portions of the duodenum. We describe a case of giant diverticulum of the transverse duodenum, revealed by UGI and angiography, massive gastrointestinal bleeding in a 80-year-old patient.=20.

    Full Text Available Objective To investigate the indications and therapeutic effect of duodenum-preserving pancreatic head resection (DPPHR. Methods A retrospective analysis was performed for the clinical data of 17 patients who underwent DPPHR in Fujian Provincial Hospital from January 2013 to February 2017. Among these patients, 6 had chronic pancreatitis with pancreatic duct stones, 2 had chronic pancreatitis with pancreatic pseudocyst, 3 had solid pseudopapillary tumor of the pancreatic head, 3 had intraductal papillary mucinous neoplasm, 2 had serous cystadenoma of the pancreatic head, and 1 had mucinous cystadenoma of the pancreatic head. Results The time of operation was 200-360 minutes (mean 304.0±45.3 minutes, and the intraoperative blood loss was 50-500 ml (mean 267.5±116.1 ml. No patient died in the perioperative period. After surgery, 5 experienced biochemical leak, 2 experienced grade B pancreatic fistula, no patient experienced grade C pancreatic fistula, and 1 experienced gastroplegia; all these patients were cured and discharged after conservative treatment. The length of postoperative hospital stay was 17-78 days (mean 30.8±14.3 days. The 17 patients were followed up for 2 months to 4 years after surgery, and no patient experienced tumor recurrence, new-onset diabetes, dyspepsia, or common bile duct stenosis after surgery. Conclusion Besides ensuring the complete resection of tumor, DPPHR can reduce the incidence rate of surgical trauma and complications and shorten the time of operation and the length of hospital stay. Compared with pancreaticoduodenectomy, DPPHR can better preserve the endocrine and exocrine functions of the pancreas and improve patients′ postoperative quality of life.

  7. Duodenum-preserving total pancreatic head resection for benign cystic neoplastic lesions.

    Beger, Hans G; Schwarz, Michael; Poch, Bertram

    2012-11-01

    Cystic neoplasms of the pancreas are diagnosed frequently due to early use of abdominal imaging techniques. Intraductal papillary mucinous neoplasm, mucinous cystic neoplasm, and serous pseudopapillary neoplasia are considered pre-cancerous lesions because of frequent transformation to cancer. Complete surgical resection of the benign lesion is a pancreatic cancer preventive treatment. The application for a limited surgical resection for the benign lesions is increasingly used to reduce the surgical trauma with a short- and long-term benefit compared to major surgical procedures. Duodenum-preserving total pancreatic head resection introduced for inflammatory tumors in the pancreatic head transfers to the patient with a benign cystic lesion located in the pancreatic head, the advantages of a minimalized surgical treatment. Based on the experience of 17 patients treated for cystic neoplastic lesions with duodenum-preserving total pancreatic head resection, the surgical technique of total pancreatic head resection for adenoma, borderline tumors, and carcinoma in situ of cystic neoplasm is presented. A segmental resection of the peripapillary duodenum is recommended in case of suspected tissue ischemia of the peripapillary duodenum. In 305 patients, collected from the literature by PubMed search, in about 40% of the patients a segmental resection of the duodenum and 60% a duodenum and common bile duct-preserving total pancreatic head resection has been performed. Hospital mortality of the 17 patients was 0%. In 305 patients collected, the hospital mortality was 0.65%, 13.2% experienced a delay of gastric emptying and a pancreatic fistula in 18.2%. Recurrence of the disease was 1.5%. Thirty-two of 175 patients had carcinoma in situ. Duodenum-preserving total pancreatic head resection for benign cystic neoplastic lesions is a safe surgical procedure with low post-operative morbidity and mortality.

    Intraluminal erosion of a laparoscopic gastric band into the stomach has been reported as a complication of laparoscopic adjustable gastric banding. To our knowledge, however, intraluminal erosion of the band tubing into the duodenum has not been described. We report a 46-year-old man in whom a laparoscopic adjustable gastric band tubing eroded into the duodenal lumen, causing recurrent port-site infections. This complication was diagnosed on upper endoscopy and also, in retrospect, on an upper gastrointestinal barium study and computed tomography. The patient underwent surgical removal of the band and tubing, with a primary duodenal repair, and made a complete recovery without complications. Erosion of laparoscopic band tubing into the duodenum should be included in the differential diagnosis for recurrent port-site infections after laparoscopic adjustable gastric banding. Radiographic or endoscopic visualization of the intraluminal portion of the tubing may be required for confirmation. Definitive treatment of this complication entails surgical removal of the tubing from the duodenum.

    Full Text Available Abstract Background The aim of this study is evaluating the correlation of postprandial fullness with chronic gastritis or rapid inflow of gastric content into duodenum, based on double-contrast barium X-ray imaging. Methods 253 healthy subjects who underwent upper gastrointestinal barium X-ray examination were analyzed. Chronic gastritis was judged from mucosal atrophy and hypertrophic thickened folds on barium X-ray images. For the gastric excretion, the tips of barium flow on the single-contrast frontal barium X-ray images of the stomach were classified into four categories; V type (all the barium remained in the stomach, V-H type (some barium had flowed into the duodenum but the tip of barium remained in the proximal half of the duodenal bulb, H-V type (some barium had flowed into the duodenum and the tip of barium was in the distal half of duodenal the bulb, but no barium was observed in the descending part of the duodenum, and H type (some barium had flowed into the descending part of the duodenum. The chi-square test and Cochran-Mantel-Haenzel test were used for evaluation. Results Chronic gastritis was observed in 72 subjects, among which 21 subjects (29.2% presented with postprandial fullness. For the remaining 181 subjects without chronic gastritis, 53 subjects (29.3% complained of postprandial fullness. There is no significant correlation between chronic gastritis and postprandial fullness (p = 0.973. For the rapid flow of gastric content into duodenum, all the 253 subjects comprised 136 subjects with V type (in the stomach, 40 subjects with V-H type (in the proximal half of the duodenal bulb, 21 subjects with H-V type (in the distal half of the duodenal bulb, and 56 subjects with H type (in the descending part of the duodenum.

Methods 253 healthy subjects who underwent upper gastrointestinal barium X-ray examination were analyzed. Chronic gastritis was judged from mucosal atrophy and hypertrophic thickened folds on barium X-ray images. For the gastric excretion, the tips of barium flow on the single-contrast frontal barium X-ray images of the stomach were classified into four categories; V type (all the barium remained in the stomach), V-H type (some barium had flowed into the duodenum but the tip of barium remained in the proximal half of the duodenal bulb), H-V type (some barium had flowed into the duodenum and the tip of barium was in the distal half of duodenal the bulb, but no barium was observed in the descending part of the duodenum), and H type (some barium had flowed into the descending part of the duodenum). The chi-square test and Cochran-Mantel-Haenzel test were used for evaluation. Results Chronic gastritis was observed in 72 subjects, among which 21 subjects (29.2%) presented with postprandial fullness. For the remaining 181 subjects without chronic gastritis, 53 subjects (29.3%) complained of postprandial fullness. There is no significant correlation between chronic gastritis and postprandial fullness (p = 0.973). For the rapid flow of gastric content into duodenum, all the 253 subjects comprised 136 subjects with V type (in the stomach), 40 subjects with V-H type (in the proximal half of the duodenal bulb), 21 subjects with H-V type (in the distal half of the duodenal bulb), and 56 subjects with H type (in the descending part of the duodenum). Postprandial fullness was present in 30 subjects with V type (22.1%), 9 subjects with V-H type (22.5%), 8 subjects with H-V type (38.1%), and 27 subjects with H type (48.2%). There is a distinct correlation between postprandial

    Gangliocytic paraganglioma (GP) is a rare benign neuroendocrine tumour found most often in the duodenum. To our knowledge, only a dozen cases of possibly malignant duodenal GP with local lymph node metastasis and only one case with liver metastasis have previously been published. Herein, we report...... an unusual case of GP of the duodenum spreading to the retropancreatic space and metastatic to the liver and lymph nodes. Additionally, the present tumour secreted pancreatic polypeptide (PP) which was detected in the serum during the follow-up period. We suggest that serum PP could be a valuable marker...

    Hydatid disease is a worldwide zoonosis and is localized in the liver in most cases. Its complications are numerous and include those related to the compression of adjacent viscera, infection of the cyst's contents or perforation of the cyst. Spontaneous rupture of the hepatic hydatid cyst into the duodenum is an extremely rare complication. The communication is, typically, not discovered until surgery. We present two cases of perforation of a liver cyst into the duodenum. One of them was diagnosed pre-operatively by a barium study. The surgical treatment of the lesion and its complications was complex but successful in both cases. (author)

    Full Text Available Iron is an essential trace element whose absorption is usually tightly regulated in the duodenum. HFE-related hereditary hemochromatosis (HH is characterized by abnormally low expression of the iron-regulatory hormone, hepcidin, which results in increased iron absorption. The liver is crucial for iron homeostasis as it is the main production site of hepcidin. The aim of this study was to explore and compare the genome-wide transcriptome response to Hfe deficiency and dietary iron overload in murine liver and duodenum. Illumina arrays containing over 47,000 probes were used to study global transcriptional changes. Quantitative RT-PCR (Q-RT-PCR was used to validate the microarray results. In the liver, the expression of 151 genes was altered in Hfe(-/- mice while dietary iron overload changed the expression of 218 genes. There were 173 and 108 differentially expressed genes in the duodenum of Hfe(-/- mice and mice with dietary iron overload, respectively. There was 93.5% concordance between the results obtained by microarray analysis and Q-RT-PCR. Overexpression of genes for acute phase reactants in the liver and a strong induction of digestive enzyme genes in the duodenum were characteristic of the Hfe-deficient genotype. In contrast, dietary iron overload caused a more pronounced change of gene expression responsive to oxidative stress. In conclusion, Hfe deficiency caused a previously unrecognized increase in gene expression of hepatic acute phase proteins and duodenal digestive enzymes.

    Full Text Available Fournier's disease, a form of necrotizing fasciitis, is a rapidly progressing subcutaneous infection of the male genitalia. We report a case of Fournier's disease with the unusual etiology of a perforated duodenum. This patient suffered from progressive right scrotal swelling after percutaneous transhepatic cholangeal drainage. Scrotal exploration revealed a large abscess with muscle necrosis that had spread up to the right retroperitoneal space. Radiologic studies and second abdominal exploration documented the origin as a perforated duodenum. The pus distribution in this case suggested that the infection process differed from that in previous reports. In future cases of Fournier's disease involving previous abdominal events, we recommend that abdominal origins be carefully surveyed before scrotal exploration.

    A duodenal adenocarcinoma arising from the junction of the second and third portion of the duodenum, which was resected by pancreas-sparing duodenectomy, is reported. The completely obstructing tumour was circumferential and measured 6.5cm x 3.5cm x 1.0 cm. There was no evidence of pancreas invasion, nor any lymph node metastasis. Pancreas-sparing duodenectomy was performed, with dissection of the pancreaticoduodenal lymph nodes. The proximal duodenum was transected just distal to the ampula of Vater and jejunum was transected just distal to the ligament of Treitz. A hand-sewn side-to-side anastomosis for the duodenojejunostomy was performed. There were no postoperative complications. Pathology reported a duodenal adenocarcinoma resected with negative margins. Pancreaticoduodenectomy is the treatment of choice for a duodenal adenocarcinoma, however, pancreas-sparing duodenectomy may be a safe alternative for duodenal tumours not involving the 2(nd) portion, especially in elderly patients with multiple medical comorbidities. © JSCR.

    An investigation was made of how effective various therapeutic techniques are in treating stomach and duodenum ulcers. The investigation was made on 105 patients (70 patients were affected by duodenum ulcer and 25 patients suffered from stomach ulcer). Three different complex laser therapeutic techniques were compared with each other and with a generally accepted drug treatment. It was found that the most pronounced therapeutic effect was observed in patients administered a complex laser technique that included drug therapy, the intravenous laser irradiation of blood, and the focal-segmental laser therapy. This complex laser therapy enabled ulcer scarring within 8 to 15 days after the beginning of the treatment (with the average scarring term of 9 days).

    It is suggested to use metoclopramide (reglan) which is introduced in a dose of 10 ml 10 min before the study intramuscularly at radio X-ray examination of the stomach and duodenum. Peroral application of the drug is not effective. The authors' experience is based on the drug application in 19 healthy persons and 89 patients with the diseases of stomach and duodenum. In patients with gastric ulcer reglan helped in the detection of the niche symptom. The use of the drug facilitated visualization of the pylorus in the case of its organic stenosis. In patients with ulcer of the duodenal bulb after introduction of reglan a better contrasting of the intestine was observed which promoted to the niche detection. An antiemetic property of reglan which can be used in patients, who do not tolerate barium suspension is also pointed out

    Full Text Available Abstract Background CREST (Calcinosis, Raynaud's phenomenon, Esophageal dysmotility, Sclerodactyly and Telangiectasias syndrome has been rarely associated with other malignancies (lung, esophagus.This is the first report of a primary adenocarcinoma of the third portion of the duodenum in a patient with CREST syndrome. Case presentation A 54-year-old male patient with CREST syndrome presented with colicky postprandial pain of the upper abdomen, diminished food uptake and a 6-Kg-body weight loss during the previous 2 months. An ulcerative lesion in the third portion of the duodenum was revealed during duodenoscopy, with a diagnosis of adenocarcinoma on biopsy specimen histology. The patient underwent a partial pancreatoduodenectomy. No adjuvant therapy was instituted and follow-up is negative for local recurrence or metastases 21 months postoperatively. Conclusion CREST syndrome has been associated with colon cancer, gastric polyps, familial adenomatous polyposis (FAP syndrome and Crohn's disease; however, this is the first report of a primary adenocarcinoma of the duodenum in a patient with CREST syndrome. However, any etiologic relationship remains to be further investigated.

    A duodenum-preserving pancreatic head resection (DPPHR) was first reported by Beger et al. in 1980. However, its application has been limited to chronic pancreatitis because of it is a subtotal pancreatic head resection. In 1990, we reported duodenum-preserving total pancreatic head resection (DPTPHR) in 26 cases. This opened the way for total pancreatic head resection, expanding the application of this approach to tumorigenic morbidities such as intraductal papillary mucinous tumor (IMPT), other benign tumors, and small pancreatic cancers. On the other hand, Nakao et al. reported pancreatic head resection with segmental duodenectomy (PHRSD) as an alternative pylorus-preserving pancreatoduodenectomy technique in 24 cases. Hirata et al. also reported this technique as a new pylorus-preserving pancreatoduodenostomy with increased vessel preservation. When performing DPTPHR, the surgeon should ensure adequate duodenal blood supply. Avoidance of duodenal ischemia is very important in this operation, and thus it is necessary to maintain blood flow in the posterior pancreatoduodenal artery and to preserve the mesoduodenal vessels. Postoperative pancreatic functional tests reveal that DPTPHR is superior to PPPD, including PHSRD, because the entire duodenum and duodenal integrity is very important for postoperative pancreatic function.

    Benign submucosal lesions of the stomach and duodenum are occasionally encountered during endoscopy. But endoscopy has its limitations in the diagnosis and differentiation of these lesions, because submucosal lesions are often difficult to visualize at endoscopy due to minimal change of the overlying mucosa. Furthermore, endoscopic biopsy may not always yield adequate tissue for diagnosis due to the submucosal location of the lesions. For this reason, the role of radiologic imaging is important in the diagnosis of submucosal lesions of the stomach and duodenum. Recent advances in computed tomography (CT) and sonographic technology are helpful in narrowing the differential diagnosis of gastroduodenal submucosal lesions. In contrast to endoscopy and barium studies, CT or ultrasonography (US) provides information about both the gastric wall and the extragastric extent of the disease. Arterial phase contrast enhanced CT enables us to discriminate a mass of submucosal from that of a mucosal origin in the differential diagnosis of gastric or duodenal lesions. Although endoscopic sonography has been considered the better modality in the diagnosis of gastroduodenal submucosal lesions, transabdominal sonography can still be an alternative method to endoscopic sonography in assessing of the origin and character of the submucosal lesions. Some gastroduodenal submucosal lesions have similar radiologic findings that make differentiation difficult. But despite overlaps in radiologic findings, some lesions have characteristic radiologic features that may suggest a specific diagnosis. Knowledge of the differential diagnosis of benign submucosal lesions in the stomach and duodenum may promote correct diagnosis and appropriate treatment

    Pancreatic injuries are rare complications after blunt abdominal trauma and usually the result of a direct force separating the pancreatic body in front of the vertebral column. This case report describes the uncommon event of a severe pancreatic and duodenal injury (stage IV b of Lukas) in which the combination of a direct force and the setting of a preexisting penetrating ulcer of the duodenum caused the extent of the pancreatic and duodenal injury [9]. Because of the preexisting lesion a Whipple procedure had to be performed. This case report demonstrates the influence of chronic abdominal diseases on the outcome of blunt abdominal trauma.

    We studied the effect of chronic aspirin ingestion on gastroduodenal epithelial proliferation by feeding rats aspirin in the drinking water. A control group of rats received plain water. At the end of 4 wk, [3H]-thymidine was given intravenously to label proliferating cells, and the rats were killed 1 h later. Sections of fundus, antrum, and proximal duodenum were processed for light autoradiography. We found that chronic aspirin ingestion stimulated epithelial proliferation in fundic mucosa but had no effect in the antrum. In the duodenum, aspirin increased proliferation in the lowest four crypt-cell positions, which most likely indicates an increase in stem-cell production. None of the tissues contained evidence of inflammation or ulceration. The proliferative effects of aspirin may help explain the previously observed phenomenon of mucosal adaptation in the rat after repeated exposure to aspirin. Further, if human gastroduodenal epithelium responds in a similar manner to chronic aspirin exposure, the effects on proliferation may explain in part the distribution of aspirin-associated ulcers

    To determine the effect of prokinetic agents such as domperidone, mosapride, clarithromycin, and itopride on the electrical activity of the stomach and duodenum in SD rats,and also to explore the mechanism. The organism functional experiment system BL-420E was used to record the myoelectrical activity in the stomach and duodenum of SD rats in all groups using domperidone, mosapride, itopride, clarithromycin, and physiological saline on the interdigestive phase. The effect of the prokinetic agents on the amplitude and frequency of gastric and duodenal electromyogram in the SD rats was compared. The antagonists such as atropine, phentolamine, and propranolol were added to investigate the mechanism of action with all prokinetic agents. All prokinetic agents increased the amplitude and frequency of gastric and duodenal fast waves in the SD rats(Pitopride was the most obvious among the 3 groups (Pitopride, and physiological saline were inhibited by atropine(PItopride, mosapride, domperidone, and clarithromycin can increase the amplitude and frequency of gastric and duodenal fast waves in the SD rats. The mechanism may be related to cholinergic receptors, but not adrenergic receptors.

    Full Text Available Duedonal diverticulosis is common in clinical practice. Most of duedonal diverticulosis is located at the second part of duodenum; incidence is reported as 67%, incidence of third and forth part is %20. Multiple diverticulosis of the first part of the duodenum is a rare case. There is not any knowledge togetherness of neurofibromatosis type 1 and duedonal diverticulosis. Here we reported incidentally diagnosed multiple diverticulosis of duodenum that is located in the first part in a neurofibromatosis type 1 patient with multiple neurofibromatosis nodules. Neurofibromatosis could affect various organs. Along the digestive system carcinoid tumors and neuroendocrine tumors are more encountered diseases. Endoscopic examinations and abdominal imaging may be useful for the diagnosis of gastrointestinal coexisting disease in neurofibromatosis type 1 . In conclusion neurofibromatosis type 1 could affect multiple systems and it should evaluate carefully.

    Celiac Disease (CD) is an interferon (IFN)γ-mediated duodenal hypersensitivity to wheat gluten occurring in genetically predisposed individuals. Gluten-free diet (GFD) leads to a complete remission of the disease. Vα24-restricted invariant NKT (iNKT) cells are important to maintain immune homeostasis in the gut mucosa because of their unique capacity to rapidly produce large quantities of both T-helper (Th)1 and Th2 cytokines upon stimulation. We studied the presence of these cells in the CD duodenum. Duodenal biopsies were obtained from 45 untreated-CD patients (uCD), 15 Gluten Free Diet-CD patients (GFD-CD), 44 non-inflamed non-CD controls (C-controls) and 15 inflamed non-CD controls (I-controls). Two populations from Spain and Argentina were recruited. Messenger RNA (mRNA) expression of Vα24-Jα18 (invariant TCRα chain of human iNKT cells), IFNγ and intracellular transcription factor Forkhead Box P3 (Foxp3), and flow cytometry intraepithelial lymphocyte (IEL) profile were determined. Both uCD and GFD-CD patients had higher Vα24-Jα18 mRNA levels than non-CD controls (I and C-controls). The expression of Vα24-Jα18 correlated with Marsh score for the severity of mucosal lesion and also with increased mRNA IFNγ levels. uCD and GFD-CD patients had decreased mRNA expression of FoxP3 but increased expression of Vα24-Jα18, which revealed a CD-like molecular profile. Increased numbers of iNKT cells were confirmed by flow cytometry within the intraepithelial lymphocyte compartment of uCD and GFD-CD patients and correlated with Vα24-Jα18 mRNA expression. In conclusion, we have found an increased number of iNKT cells in the duodenum from both uCD and GFD-CD patients, irrespective of the mucosal status. A CD-like molecular profile, defined by an increased mRNA expression of Vα24-Jα18 together with a decreased expression of FoxP3, may represent a pro-inflammatory signature of the CD duodenum.

    The objective of this study was to assess the efficacy and safety of pancreaticoduodenectomy (PD) and duodenum-preserving pancreatic head resection (DPPHR) for the treatment of chronic pancreatitis (CP). The 123 patients with CP who underwent pancreatic head resection between January 2004 and June 2009 were retrospectively analyzed. The preoperative variables, operative data, postoperative complications, and follow-up information were examined. There were no significant differences in clinical and morphological characteristics, pain relief, and jaundice status between the PD and DPPHR groups. The duration of operation was shorter (251.8 [SD, 43.1] vs 324.5 [SD, 41.4] minutes, P endocrine insufficiency was higher in PD group as compared with DPPHR group. Both procedures are equally effective in pain relief, but DPPHR is superior to PD in operative data, postoperative morbidity, improving quality of life, and preservation of exocrine and endocrine function.

    Full Text Available Objective  To investigate the clinicopathological characteristics and prognosis of patients with neuroendocrine tumor in stomach and duodenum for early diagnosis. Methods  The clinical, endoscopic and pathological data of 20 patients admitted to the PLA General Hospital from Jan. 2012 to Jan. 2015 and diagnosed as gastric and duodenal neuroendocrine tumor were collected for retrospective analysis. The histopathological classification of the disease was made according to the WHO 2010 Classification of the Neuroendocrine Neoplasms. Result  Ten male and 10 female patients aged between 35 and 77 (mean 55.5±10.6 years old were recruited in the present study. Tumor located in the stomach in 13 cases, and in duodenum in 7 cases. The maximum diameter of the tumor was 0.2-2.5cm. Endoscopic features included polypoid protrusion, hemispheric submucosal protrusion, and mucosal erosion. All the patients were treated endoscopically, among them, four patients were treated with electrocoagulation and electrosection, 10 by endoscopic resection (EMR, and 6 by endoscopic submucosal dissection (ESD. In one patient, surgical excision was done after ESD. Biopsy under gastroscopy and endoscopic ultrasonography were conducive to the diagnosis and treatment. According to the histopathological classification, 19 cases were classified as NET grade 1, and another one as NET grade 2. The follow-up study showed no metastasis and recurrence. Conclusions  The early diagnosis and treatment for gastric and duodenal neuroendocrine tumor can lead to satisfactory results. DOI: 10.11855/j.issn.0577-7402.2016.03.12

    The usefulness of the ultrasonography (US), the computed tomography (CT) and the magnetic resonance imaging (MRI) was examined. The subjects were 19 patients with submucosal leiomyoma and leiomyosarcoma in the stomach and duodenum which had surgery and were histologically diagnosed in the National Cancer Center Hospital. The detectability of the primary foci was 50% (8/16) in US, and 93% (13/14) in EUS (the endoscopic ultrasonography) which makes the structure of the stomach wall and the continuity of tumors clear. CT could detect the primary foci in 94% (16/17) and was excellent to know not only the presence of the remote metastases but also the exact size and expanse of the tumors. In all cases of leiomyoma, tumors were leiomyosarcoma when the internal structure was diagnosed to be heterogeneous by both EUS and CT, or either of them. The qualitative image diagnosis is not always easy in gastrointestinal submucosal tumors, but it is important to generally diagnose by the combination with several examinations in order to select the suitable therapeutic method.

    AIM: To investigate endoscopic and histopathological findings in the duodenum of patients with Strongyloides stercoralis (5. stercoralis) hyperinfection.METHODS: Over a period of 23 years (1984-2006), we investigated 25 patients with 5. stercoralis hyperinfection who had had an esophagogastroduodenoscopy before undergoing treatment for strongyloidiasis. The clinical and endoscopic findings were analyzed retrospectively.RESULTS: Twenty-four (96%) of the patients investigated were under immunocompromised condition which was mainly due to a human T lymphotropic virus type 1 (HTLV-1) infection. The abnormal endoscopic findings, mainly edematous mucosa, white villi and erythematous mucosa, were observed in 23 (92%) patients. The degree of duodenitis including villous atrophy/destruction and inflammatory cell infiltration corresponded to the severity of the endoscopic findings. The histopathologic yield for identifying larvae was 71.4% by duodenal biopsy. The endoscopic findings of duodenitis were more severe in patients whose biopsies were positive for larvae than those whose biopsies were negative (Endoscopic severity score: 4.86 ± 2.47 vs 2.71 ± 1.38, P < 0.05).CONCLUSION: Our study clearly demonstrates that, in addition to stool analysis, endoscopic observation and biopsies are very important. We also emphasize that 5. stercoralis and HTLV-1 infections should be ruled out before immunosuppressive therapy is administered in endemic regions.

    Feed represents two-thirds of the total costs of poultry production, especially in developing countries. Improvement in feed efficiency would reduce the amount of feed required for production (growth or laying), the production cost, and the amount of nitrogenous waste. The most commonly used measures for feed efficiency are feed conversion ratio (FCR) and residual feed intake (RFI). As a more suitable indicator assessing feed efficiency, RFI is defined as the difference between observed and expected feed intake based on maintenance and growth or laying. However, the genetic and biological mechanisms regulating RFI are largely unknown. Identifying molecular mechanisms explaining divergence in RFI in laying ducks would lead to the development of early detection methods for the selection of more efficient breeding poultry. The objective of this study was to identify duodenum genes and pathways through transcriptional profiling in 2 extreme RFI phenotypes (HRFI and LRFI) of the duck population. Phenotypic aspects of feed efficiency showed that RFI was strongly positive with FCR and feed intake (FI). Transcriptomic analysis identified 35 differentially expressed genes between LRFI and HRFI ducks. These genes play an important role in metabolism, digestibility, secretion, and innate immunity including (), (), (), β (), and (). These results improve our knowledge of the biological basis underlying RFI, which would be useful for further investigations of key candidate genes for RFI and for the development of biomarkers.

    The uptake of amino acids is mediated by active transporters located on the basolateral and brush border membranes of intestinal epithelial cells. The current study investigated the expression of amino acid transporters (AAT) and other genes in the intestine of chicks infected with Eimeria maxima. At 7-day postinfection (PI), tissue from each intestinal segment (duodenum, jejunum, and ileum) was taken from birds inoculated with 3 × 10(3) oocysts/bird and processed to recover RNA. Analysis of gene expression was performed using real-time reverse transcription polymerase chain reaction (qRT-PCR). Results were given as relative expression using β₂-microglobulin as an endogenous control. All the genes studied were expressed in three segments of the intestines, and expression of the genes was altered by infection with E. maxima. Even though the jejunum is considered the parasite's primary predilection site, there was no segment-related difference in expression of most of the genes studied. The antimicrobial peptide (LEAP2) was downregulated in all three segments of the intestine. The results also demonstrate that transporters associated with brush border membranes were downregulated while transporters associated with the basolateral membranes were upregulated and that E. maxima alters the expression of AAT and LEAP2 throughout the small intestine.

    Demonstration of the third duodenal segment (D3) in retroperitoneal location has been recently proposed as a method for excluding malrotation. This study was performed to determine whether a retroperitoneal third duodenal segment can reliably exclude malrotation. CTs of 38 patients with proven malrotation and 100 patients without malrotation were evaluated for the location of the duodenum/proximal small bowel, and the relationship of the superior mesenteric vein (SMV) to superior mesenteric artery (SMA). The D3 segment was in normal retroperitoneal location in 100% of control patients, compared to 2.5% or (1 of 38) of patients with malrotation. Nine of 11 patients (91%) with malrotation imaged prior to surgery had the proximal bowel in an abnormal location, while all 100 control patients had it in a normal location. The SMV was in normal relationship to the SMA in 11/38 patients (29%) with malrotation, compared to 79% of normal controls. In 10 controls, a branch of the SMV was partially wrapped around the SMA, potentially mimicking partial mesenteric volvulus. A retroperitoneal location of the D3 segment makes the diagnosis of malrotation unlikely but not impossible. Additional imaging of the duodenojejunal junction or cecum may be necessary to reliably exclude intestinal malrotation. (orig.)

    Full Text Available CONTEXT: Peripheral neuropathy is one of the chronic complications of diabetes mellitus and is directly related to gastrointestinal consequences of the disease. Myenteric neurons are affected in some pathological conditions such as diabetic neuropathy. The imbalance between cellular antioxidants and free radicals, leading to an increase in oxidative stress, is considered one of the main factors responsible for neuronal damages in diabetes. Drugs that reduce the oxidative stress may play a significant role in the treatment of neurological complications of diabetes mellitus. OBJECTIVE: To evaluate the effect of L-glutamine supplementation on the myenteric neurons from the cecum and duodenum of Wistar rats with streptozotocin-induced diabetes mellitus. METHODS: The animals were divided in four groups (n = 5: non-treated normoglycemics, normoglycemics treated with L-glutamine, non-treated diabetics and diabetics treated with L-glutamine from the 4th day of diabetes induction on. The amino acid L-glutamine was added to their diet at 1%. Giemsa's technique was employed to stain the myenteric neurons. We determined the cell body area of 500 neurons in each group studied. The quantitative analysis was performed by sampling in an area of 16.6 mm² in the cecum and 3.6 mm² in the duodenum of each animal. RESULTS: After the supplementation with L-glutamine in the duodenum, we observed a preservation of neuronal density in groups normoglycemic and diabetic (P<0.05. We also observed a preservation of the cell bodies area in diabetic animals (group treated with L-glutamine (P<0.05. In the cecum, that preservation was not evident. CONCLUSION: Supplementation with L-glutamine (1% promoted a neuroprotective effect on the myenteric neurons from the duodenum of rats, both in terms of natural aging and of diabetes mellitus.

    An artificial stomach duodenum (ASD) model has been used to demonstrate the performance difference between two formulations of LY2300559, a low-solubility acidic developmental drug. The two formulations investigated were a conventional high-shear wet granulation (HSWG) formulation and a solid dispersion formulation. A pharmacokinetic study in humans demonstrated the enhanced performance of the solid dispersion formulation relative to the HSWG formulation. The Cmax and AUC of the solid dispersion was 2.6 and 1.9 times greater, respectively, compared to the HSWG formulation. In the ASD, the solid dispersion formulation performance was characterized by three main phases: (1) rapid release in the stomach, creating a supersaturated concentration of drug, (2) precipitation in the stomach, and (3) rapid redissolution of the precipitate in the duodenum to concentration levels that are supersaturated relative to crystalline drug. A series of complementary experiments were employed to describe this performance behavior mechanistically. Imaging experiments with a pH indicating dye showed that local pH gradients from meglumine in the solid dispersion formulation were responsible for creating a high initial supersaturation concentration in the stomach. Upon dissipation of meglumine, the drug precipitated in the stomach as an amorphous solid. Because the precipitated drug is in an amorphous form, it can then rapidly redissolve as it transits to the more neutral environment of the duodenum. This unexpected sequence of physical state changes gives a mechanistic explanation for the enhanced in vivo performance of the solid dispersion formulation relative to the HSWG formulation.

    A cancer bioassay on hexavalent chromium Cr(VI) in drinking water reported increased incidences of duodenal tumors in B6C3F1 mice at exposures of 30-180ppm, and oral cavity tumors in F344 rats at 180ppm. A subsequent transgenic rodent (TGR) in vivo mutation assay in Big Blue® TgF344 rats found that exposure to 180ppm Cr(VI) in drinking water for 28days did not increase cII transgene mutant frequency (MF) in the oral cavity (Thompson et al., 2015). Herein, we extend our analysis to the duodenum of these same TgF344 rats. At study termination, duodenum chromium levels were below either the limit of detection or quantification in control rats, but were 24.6±3.8μg/g in Cr(VI)-treated rats. The MF in control (23.2×10 -6 ) and Cr(VI)-treated rats (22.7×10 -6 ) were nearly identical. In contrast, the MF in the duodenum of rats exposed to 1-ethyl-1-nitrosourea for six days (study days 1, 2, 3, 12, 19, 26) increased 24-fold to 557×10 -6 . These findings indicate that mutagenicity is unlikely an early initiating event in Cr(VI)-induced intestinal carcinogenesis. Copyright © 2017 Elsevier Inc. All rights reserved.

    To Improve the diagnosis of duodenal ulcer and preneoplastic changes of gastroduodenal transition. 112 patients with duodenal ulcer, 208 healthy pearsons of three age periods: second period of mature age, elderly and senile age were examined. Video endoscopy equipment company "OLYMPUS" (Japan), morphological methods and the determination of Helicobacter pylori (Hp) were used. The connecting line of gastric and duodenal mucous membrane can be located on the gastric side of the pylorus (13% in normal cases and 22.3% in cases of ulcer disease), on pylorus and go into the bulbus of duodenum (87% and 77.7 %, respectively), in cases of duodenal ulcer the connecting line more often has jagged and tongue-shaped form. Mucous membrane forms folds in prepyloric part of the stomach most often on the front wall in healthy pearsons in 14.4% of cases, in patients with duodenal ulcer--in 75.9%. The number of folds decreases with age. HP, atrophy, intestinal metaplasia of the mucous membrane is more often found in duodenal ulcer disease--76.8%, 69.7% and 62.5% comparing with healthy persons: 51.4%, 5.3% and 47.7% respectively. Frequency of preneoplastic changes increases with age. The individual differences of the mucous membrane of the gastroduodenal transition are identified. They are expressed in the particular location and shape of the connecting line of gastric and duodenal mucous membranes in normal cases and in cases of ulcer disease in different age groups. Some endoscopic changes requiring biopsy and morphological studies are revealed.

    Epithelia cover the internal and external surfaces of the organism and form barriers between the various compartments. Some of these epithelia are specialized for effective transmembrane or even transepithelial movement of acid-base equivalents. Certain epithelia with a high rate of HCO3- transport express a few potent Na+-coupled acid-base transporters to gain a net HCO3- movement across the epithelium. Examples of such epithelia are renal proximal tubules and pancreatic ducts. In contrast, multiple Na+-coupled HCO3- transporters are expressed in other HCO3- secreting epithelia, such as the duodenal mucosa or the choroid plexus, which maintain suitable intracellular pH despite a variable demand for secreting HCO3-. In the duodenum, the epithelial cells must secrete HCO3- for neutralization of the gastric acid, and at the same time prevent cellular acidification. During the neutralization, large quantities of CO2 are formed in the duodenal lumen, which enter the epithelial cells. This would tend to lower intracellular pH and require effective counteracting mechanisms to avoid cell death and to maintain HCO3- secretion. The choroid plexus secretes the cerebrospinal fluid (CSF) and controls the pH of the otherwise poorly buffered CSF. The pCO2 of CSF fluctuates with plasma pCO2, and the choroid plexus must regulate the HCO3- secretion to minimize the effects of these fluctuations on CSF pH. This is done while maintaining pH neutrality in the epithelial cells. Thus, the Na+-HCO3- cotransporters appear to be involved in HCO3- import in more epithelia, where Na+/H+ exchangers were until recently thought to be sufficient for maintaining intracellular pH.

    Gastrointestinal stromal tumours (GISTs) are uncommon primary mesenchymal tumours of the gastrointestinal tract mostly observed in the adults. Duodenal GISTs are relatively rare in adults and it should be regarded as exceptional in childhood. In young patients duodenal GISTs may be a source of potentially lethal haemorrhage and this adds diagnostic and therapeutic dilemmas to the concern about the long-term outcome. A 14-year-old boy was referred to our hospital with severe anaemia due to recurrent episodes of upper gastrointestinal haemorrhage. Endoscopy, small bowel series, scintigraphy and video capsule endoscopy previously done elsewhere were negative. Shortly after the admission, the patient underwent emergency surgery for severe recurrence of the bleeding. At surgery, a 4 cm solid mass arising from the wall of the fourth portion of the duodenum was identified. The invasion and the erosion of the duodenal mucosa was confirmed by intra-operative pushed duodenoscopy. The mass was resected by a full-thickness duodenal wall excision with adequate grossly free margins. Immunohistochemical analysis of the specimen revealed to be positive for CD117 (c-KIT protein) consistent with a diagnosis of GIST. The number of mitoses was < 5/50 HPF. Mutational analysis for c-KIT/PDGFRA tyrosine kinase receptor genes resulted in a wildtype pattern. The patient had an uneventful course and he has remained disease-free during two years of follow-up. Duodenal GISTs in children are very rare and may present with massive bleeding. Cure can be achieved by complete surgical resection, but even in the low-aggressive tumours the long-term outcome may be unpredictable

    Full Text Available The effects of acute and chronic infection caused by Toxoplasma gondii on duodenal myenteric neurons were analyzed. Eighteen rats were assigned into four groups: Acute Control Group (ACG, n=4; Acute Experimental Group (AEG, n=4; Chronic Control Group (CCG, n=5; and Chronic Experimental Group (CEG, n=5. Rats from the AEG and CEG were inoculated orally with 105 genotype III (BTU-II strain tachyzoites of T. gondii isolated from a dog with neurological signs. Acute groups were killed after 24 hours after the inoculation and the chronic groups after 30 days. Whole-mount from the duodenum were stained with Giemsa. The population density of myenteric neurons, as well the body cell, nuclear and cytoplasmic area were analyzed. Both acute and chronic toxoplasmic infection did not provoke neuronal loss. On the other hand, plastic alterations were observed: decreasing of the nuclear and cytoplasmic area during the acute phase and neuronal hypertrophy during the chronic phase.Foram analisados os efeitos da infecção aguda e crônica provocada pelo Toxoplasma gondii sobre os neurônios mientéricos do duodeno.

    Gastro-oesophageal reflux disease (GORD) is a very common paediatric disorder and the majority of patients are treated successfully by primary care physicians. Two infants aged 2 months with GORD which did not respond to conventional medical management are reported; they were diagnosed with duodenum inversum. The first infant failed medical management and required Nissen's fundoplication to control his symptoms. The second infant improved on maximizing medical management without the need for a surgical procedure. These two cases highlight the need for further work-up in patients who do not respond to conventional GORD therapy and/or present with atypical clinical symptoms.

    We report a case of recurrent transverse colon cancer invading the pancreas and duodenum that was successfully treated with biliary and duodenal stenting. A 46-year-old man underwent ascending colostomy for the treatment of obstructive transverse colon cancer with hepatic metastasis. Chemotherapy achieved a partial response, but the levels of tumor markers later began to rise again. He then underwent right hemicolectomy and partial hepatectomy. Post-operative chemotherapy was administered, but the recurrent tumor caused obstructive jaundice and duodenal obstruction. These were successfully treated with biliary and duodenal stenting, and the patient was able to remain at home and maintain his quality of life.

    The objective of this study was to develop an artificial stomach-duodenum (ASD) dissolution model as an in vitro evaluation tool that would simulate the gastrointestinal physiology of gastric pH-reduced dogs as a method to assess formulations for a poorly soluble free acid compound with ng/mL solubility. After establishing the ASD model with well-controlled duodenum pH, 5 formulations each applying different solubilization principles were developed and their performance in the ASD model and in vivo in dogs was evaluated. Excellent correlations were obtained between dog area under the curve (AUC) and ASD AUC of 5 formulations evaluated with simulated intestinal fluid (r 2  = 0.987) and fasted-state simulated intestinal fluid (r 2  = 0.989) as the duodenum dissolution medium, indicating that the approach of infusing NaOH into duodenum compartment to maintain duodenum pH of an ASD worked properly in simulating gastric pH-reduced dog. Raman spectroscopy was used to study drug dissolution kinetics associated with different solubilization principles and the results suggested that the solubilization principles performed as designed. Spectroscopic results also identified that the compound formed a gel during dissolution and hypromellose maintained the drug-gelled state to avoid further solid form conversion. The implication of the compound physical gelation to drug dissolution kinetics and in vivo exposure are discussed. Copyright © 2017 American Pharmacists Association®. Published by Elsevier Inc.

    We present a resected case of annular pancreas in which Wirsung's duct encircled the duodenum and continued directly to the main pancreatic duct in the body and tail. Furthermore, Wirsung's duct coursed along the right side of the lower bile duct near the major duodenal papilla. Histologically, the islets of Langerhans in the annular pancreas were irregular in shape and were characterized by a striking abundance of pancreatic polypeptide (PP)-positive cells. The PP-rich area that encircled the duodenum was fused with the PP-poor area in the head of the pancreas. The following embryological hypothesis is proposed. The tip of the ventral pancreatic anlage adhered to the duodenal wall and stretched to form a ring during clockwise rotation. The rotation was incomplete, and the pancreatic duct did not cross over the lower bile duct. Since there was adequate ventral anlage in the lower part of the head of the pancreas, fusion between the ducts of the ventral and dorsal anlagen did not occur. The tip of the ventral anlage overgrew and adhered to the dorsal anlage, and the annular duct fused with the main duct of the dorsal anlage.

    The embryonic chick duodenum contains no vitamin D-induced, calcium-binding protein (CaBP). However, when maintained in organ culture, the duodenum responds to 1α,25-(OH) 2 -D 3 in the culture medium by de novo synthesis of CaBP. Studies with this system have provided evidence that CaBP is directly involved in calcium transport at least at the mucosal surface. The present paper extends previous observations on the effects of the extremely toxic environmental pollutant, cadmium. Cadmium was found to inhibit 1α,25-(OH) 2 -D 3 -mediated responses in the organ-cultured duodenum, i.e., CaBP biosynthesis and 45 Ca uptake at the mucosal surface. Cadmium also stimulated concomitent production of a specific metallothionein (MT). Zinc had similar actions in inhibiting CaBP and stimulating Mt biosynthesis

    To define influence of the comorbidity diseases and risk factors of development of the combined peptic ulcer of a stomach and duodenum. As a result of carried-out poll and inspection 250 patients with an exacerbation of a peptic ulcer were surveyed. Patients were distributed in 3 groups of observation depending on localization of ulcerative process. At all surveyed questioning was carried out, data on hereditary load, smoking, alcohol intake, existence of somatopathies were specified, clinic-morphological implications of a peptic ulcer were studied. The peptic ulcer of a stomach is characteristic for women (72.1%) and develops mainly aged from 45 till 59 years (60.3%). Peptic ulcer of duodenum men (76.3%) suffer mainly, the debut is the share in most cases of age from 18 to 44 years (79.1%). The combined canker of a stomach and duodenum meets at males (61.2%) more often, is initially involved in process ulcerogenesis by duodenum generally aged from 30 till 44 years (64.2%), accession of a canker of a stomach happens is delayed (at 38.8% within 16 and more years). In the analysis of risk factors at patients with the combined peptic ulcer of a stomach and duodenum depending on existence or absence specific to this category of patients of a background from such comorbidity diseases as IBS, HOBL and widespread osteochondrosis taped that larger prevalence of smoking (100%) and as the use (50%) and the excessive use (50%), alcohol are characteristic for the patients having a high comorbidity (a combination of three above nosologies). The greatest interest in respect of possible communication with formation of the combined peptic ulcer of a stomach and duodenum is represented by IBS, HOBL and osteochondrosis. And major factors of risk were smoking, the excessive alcohol intake, the burdened heredity.

    Purpose: Dose limiting structures, such as the duodenum, render the treatment of pancreatic cancer challenging. In this multi-institutional study, we assess dosimetric differences caused by interfraction pancreas-to-duodenum motion using MR-IGRT to determine the potential impact of adaptive replanning. Methods: Ten patients from two institutions undergoing MRI-guided radiotherapy with conventional fractionation (n=5) or SBRT (n=5) for pancreatic cancer were included. Initial plans were limited by duodenal dose constraints of 50 Gy (0.5 cc)/31 Gy (0.1 cc) for conventional/SBRT with prescriptions of 30 Gy/5 fractions (SBRT) and 40–50 Gy/25 fractions (conventional). Daily volumetric MR images were acquired under treatment conditions on a clinical MR-IGRT system. The correlation was assessed between interfractional GTV-to-duodenum positional variation and daily recalculations of duodenal dose metrics. Positional variation was quantified as the interfraction difference in Hausdorff distance from simulation baseline (ΔHD) between the GTV and proximal duodenal surface, or volume overlap between GTV and duodenum for cases with HD_0=0 (GTV abutting duodenum). Adaptation was considered indicated when daily positional variations enabled dose escalation to the target while maintaining duodenal constraints. Results: For fractions with ΔHD>0 (n=14, SBRT only), the mean interfraction duodenum dose decrease from simulation to treatment was 44±53 cGy (maximum 136 cGy). A correlation was found between ΔHD and dosimetric difference (R"2=0.82). No correlation was found between volume of overlap and dosimetric difference (R"2=0.31). For 89% of fractions, the duodenum remained overlapped with the target and the duodenal dose difference was negligible. The maximum observed indication for adaptation was for interfraction ΔHD=11.6 mm with potential for adaptive dose escalation of 136 cGy. Conclusion: This assessment showed that Hausdorff distance was a reasonable metric to use to

    Purpose: Dose limiting structures, such as the duodenum, render the treatment of pancreatic cancer challenging. In this multi-institutional study, we assess dosimetric differences caused by interfraction pancreas-to-duodenum motion using MR-IGRT to determine the potential impact of adaptive replanning. Methods: Ten patients from two institutions undergoing MRI-guided radiotherapy with conventional fractionation (n=5) or SBRT (n=5) for pancreatic cancer were included. Initial plans were limited by duodenal dose constraints of 50 Gy (0.5 cc)/31 Gy (0.1 cc) for conventional/SBRT with prescriptions of 30 Gy/5 fractions (SBRT) and 40–50 Gy/25 fractions (conventional). Daily volumetric MR images were acquired under treatment conditions on a clinical MR-IGRT system. The correlation was assessed between interfractional GTV-to-duodenum positional variation and daily recalculations of duodenal dose metrics. Positional variation was quantified as the interfraction difference in Hausdorff distance from simulation baseline (ΔHD) between the GTV and proximal duodenal surface, or volume overlap between GTV and duodenum for cases with HD{sub 0}=0 (GTV abutting duodenum). Adaptation was considered indicated when daily positional variations enabled dose escalation to the target while maintaining duodenal constraints. Results: For fractions with ΔHD>0 (n=14, SBRT only), the mean interfraction duodenum dose decrease from simulation to treatment was 44±53 cGy (maximum 136 cGy). A correlation was found between ΔHD and dosimetric difference (R{sup 2}=0.82). No correlation was found between volume of overlap and dosimetric difference (R{sup 2}=0.31). For 89% of fractions, the duodenum remained overlapped with the target and the duodenal dose difference was negligible. The maximum observed indication for adaptation was for interfraction ΔHD=11.6 mm with potential for adaptive dose escalation of 136 cGy. Conclusion: This assessment showed that Hausdorff distance was a reasonable

    There is a clear consensus regarding the combined resection of organs with cancer invasion, patients with colon cancer. However, there are very few reports to our knowledge regarding the use of pancreato-duodenectomy(PD)for colon cancer patients with cancer invasion in the duodenum. We here report a colon cancer patient in whom we performed PD and right hemicolectomy, who showed favorable results with no recurrence. The patient was a 69-year-old woman. Her chief complaint was hypogastric pain. Her previous doctor performed colonoscopy and a colonoscopic biopsy, and detected a type 2 lesion, throughout the entire circumference of the transverse colon near the liver, and she was diagnosed with adenocarcinoma. From further imaging analyses, she was diagnosed as having transverse colon cancer with invasion into the superior mesenteric vein(SMV), duodenum, and pancreatic head, and No. 223 lymph node metastasis. The patient's cancer was concluded to be unresectable, and she underwent chemotherapy, namely mFOLFOX6 with cetuxiumab(Cmab). One course of mFOLFOX with Cmab, the patient decided to consult our hospital for a second opinion. We concluded that her cancer was resectable, so we performed PD, right hemicolectomy, and resection and reconstruction of a part of the SMV. The operation time was 5 hours 17 minutes, and total blood loss was 190 mL. The histopathological diagnosis was tub2, T4b(duodenum and, tissue surrounding the SMV), int, INF b, ly1, v2, PN1b, EX(+)/ND(PN+, v+), PM0(25 cm), DM0(14.3 cm), N1(1/ 20), H0, P0, M0, pStage III a. She was discharged 15 days after surgery with no complications, and thereafter received ajduvant chemotherapy(capecitabine with oxaliplatin)as an outpatient. After 3 courses, capecitabine with oxaliplatin was changed to capecitabine because she developed a nervous system disorder, and she was further treated for approximately about 6 months. She is doing well at the time of writing, with no recurrences for 2 years. We suggest that PD

    Either vitamin D 3 (or 1 α,25-(OH) 2 -D 3 ) or hydrocortisone (HC) stimulated phosphate accumulation by organ-cultured embryonic chick duodenum. In combination, these two steroids stimulated phosphate uptake synergistically. Phosphate accumulation appeared to be independent of other vitamin D 3 -stimulated processes: CaBP concentration, cAMP concentration, or alkaline phosphataseactivity. L-phenylalanine, a reported alkaline phosphate inhibitor, when added to the culture medium progressively inhibited either D 3 - or HC-stimulated phosphate uptake subsequent to culture, but did not inhibit the synergistic action under these conditions L-phenylalanine had no consistent effect on alkaline phosphotase activity but unexpectedly, greatly inhibited vitamin D 3 - stimulated CaBP concentration, but only in the absence of HC. Some limited suggestion of an intestinal phosphoprotein sensitve to either vitamin D 3 or HC was observed. (orig.) [de

    Retention of intact plant cells to the end of the small intestine leads to transport of entrapped macronutrients such as starch and protein for colonic microbial fermentation, and is a promising mechanism to increase the content of resistant starch in diets. However, the effect of gastro-intestinal bio-mechanical processing on the intactness of plant cells and the subsequent resistance to enzymatic digestion of intracellular starch and protein are not well understood. In this study, intact cells isolated from legume cotyledons are digested in a laboratory model which mimics the mechanical and biochemical conditions of the rat stomach and duodenum. The resulting digesta are characterised in terms of cell (wall) integrity as well as intracellular starch and protein hydrolysis. The cells remained essentially intact in the model with negligible (ca. 2-3%) starch or protein digestion; however when the cells were mechanically broken and digested in the model, the hydrolysis was increased to 45-50% suggesting that intact cellular structures could survive the mixing regimes in the model stomach and duodenum sufficiently to prevent digestive enzyme access. Apart from intact cell walls providing effective barrier properties, they also limit digestibility by restricting starch gelatinisation during cooking, and significant non-specific binding of α-amylase is observed to both intact and broken cell wall components, providing a third mechanism hindering starch hydrolysis. The study suggests that the preservation of intactness of plant cells, such as from legumes, could be a viable approach to achieve the targeted delivery of resistant starch to the colon.

    Celiac disease (CD) affects around 1% of the global population and can cause serious long-term symptoms including malnutrition, fatigue, and diarrhea, amongst others. Despite this, it is often left undiagnosed. Currently, a tissue diagnosis of CD is made by random endoscopic biopsy of the duodenum to confirm the existence of microscopic morphologic alterations in the intestinal mucosa. However, duodenal endoscopic biopsy is problematic because the morphological changes can be focal and endoscopic biopsy is plagued by sampling error. Additionally, tissue artifacts can also an issue because cuts in the transverse plane can make duodenal villi appear artifactually shortened and can bias the assessment of intraepithelial inflammation. Moreover, endoscopic biopsy is costly and poorly tolerated as the patient needs to be sedated to perform the procedure. Our lab has previously developed technology termed tethered capsule OCT endomicroscopy (TCE) to overcome these diagnostic limitations of endoscopy. TCE involves swallowing an optomechanically-engineered pill that generates 3D images of the GI tract as it traverses the lumen of the organ via peristalsis, assisted by gravity. In several patients we have demonstrated TCE imaging of duodenal villi, however the current TCE device design is not optimal for CD diagnosis as the villi compress when in contact with the smooth capsule's wall. In this work, we present methods for structuring the outer surface of the capsule to improve the visualization of the villi height and crypt depth. Preliminary results in humans suggest that new TCE capsule enables better visualization of villous architecture, making it possibly to comprehensively scan the entire duodenum to obtain a more accurate tissue diagnosis of CD.

    Full Text Available Non-Hodgkin's lymphoma of B-cell type is the second most common neoplasm after Kaposi's sarcoma, among patients with human immunodeficiency virus infection. Most non-Hodgkin's lymphoma cases that are associated with acquired immunodeficiency syndrome involve extranodal sites, especially the digestive tract and the central nervous system. We report a case of primary lymphoma of the duodenum in a patient with AIDS. Upper gastrointestinal endoscopy revealed pseudopolypoid masses found in the second portion of the duodenum. A complete diagnostic study including histological, immunohistochemical and virological analyses showed high-grade B-cell Burkitt's lymphoma. The Epstein-Barr virus genome was detected in biopsies by immunohistochemical and in situ hybridization.O linfoma não-Hodgkin de células B é a segunda neoplasia mais comum em pacientes com infecção pelo vírus da imunodeficiência humana depois do sarcoma de Kaposi.

    We conducted numerical experiments to study the influence of non-propagating longitudinal and circular contractions, i.e. pendular activity and segmentation, respectively, on flow and mixing in the proximal duodenum. A lattice-Boltzmann numerical method was developed to simulate the fluid mechanical consequences for each of 22 randomly selected sequences of high-definition video of real longitudinal and radial contractile activity in the isolated proximal duodenum of the rat and guinea pig. During pendular activity in the rat duodenum, the flow was characterized by regions of high shear rate. Mixing was so governed by shearing deformation of the fluid that increased the interface between adjacent domains and accelerated their inter-diffusion (for diffusion coefficients approx. less than 10(-8) m² s(-1)). When pendular activity was associated with a slow gastric outflow characteristic of post-prandial period, the dispersion was also improved, especially near the walls. Mixing was not promoted by isolated segmentative contractions in the guinea pig duodenum and not notably influenced by pylorus outflow. We concluded that pendular activity generates mixing of viscous fluids 'in situ' and accelerates the diffusive mass transfer, whereas segmentation may be more important in mixing particulate suspensions with high solid volume ratios.

    We herein report a rare case of a massive upper gastrointestinal (GI) bleeding, caused by high-grade diffuse B-cell lymphoma of the duodenum, secondary to immunoproliferative small intestinal disease (IPSID) and treated with an emergency partial pancreatoduodenectomy. A 42-year-old man was admitted to our hospital because of hematemesis. Upper GI endoscopy was unrevealing because of the copious bleeding. Initially, the patient underwent conservative treatment, thus resulting in the temporary cessation of the bleeding. Later, the hemorrhage massively relapsed. An urgent abdominal ultrasound raised the suspicion of a large, possibly bleeding, neoplasm of the duodenum, which was finally confirmed by abdominal computed tomography. The patient underwent an emergency laparotomy, during which a partial pancreatoduodenectomy was performed (Whipple procedure). Histologically, the tumor was a high-grade B-cell lymphoma of the duodenum. The nearby small intestinal mucosa was suggestive of IPSID. A massive upper GI hemorrhage from a high-grade B-cell non-Hodgkin lymphoma of the duodenum, which develops secondary to IPSID, is a very rare clinical demonstration of this disease. Our case is one of the few reports in the English literature, for which the Whipple procedure has been performed as a curative treatment.

    Canine idiopathic inflammatory bowel disease (IBD) is believed to be caused by a complex interaction of genetic, immunologic, and microbial factors. While mucosa-associated bacteria have been implicated in the pathogenesis of canine IBD, detailed studies investigating the enteric microbiota using deep sequencing techniques are lacking. The objective of this study was to evaluate mucosa-adherent microbiota in the duodenum of dogs with spontaneous idiopathic IBD using 16 S rRNA gene pyrosequencing. Biopsy samples of small intestinal mucosa were collected endoscopically from healthy dogs (n = 6) and dogs with moderate IBD (n = 7) or severe IBD (n = 7) as assessed by a clinical disease activity index. Total RNA was extracted from biopsy specimens and 454-pyrosequencing of the 16 S rRNA gene was performed on aliquots of cDNA from each dog. Intestinal inflammation was associated with significant differences in the composition of the intestinal microbiota when compared to healthy dogs. PCoA plots based on the unweighted UniFrac distance metric indicated clustering of samples between healthy dogs and dogs with IBD (ANOSIM, pmicrobial groups, which bear resemblance to dysbiosis reported in humans with chronic intestinal inflammation. These bacterial groups may serve as useful targets for monitoring intestinal inflammation.

    Full Text Available Background/Aim. Aging is one of the most complex biological processes which probably affect structure and function of the enteric nerve system. However, there is not much available information on this topic, particularly in humans. The aim of this study was to investigate the influence of aging on the structure of the myenteric ganglia in the anterior wall of the human proximal duodenum. Methods. We examined the myenteric ganglia in the proximal duodenal anterior wall specimens obtained from 30 cadaver persons aged from 20 to 84 years. Tissue samples were classified into three age groups: 20-44, 45-64 and 65-84 years. After standard histological preparation, specimens were stained with HE, Cresyl Violet and AgNO3. Morphometric analysis of all the specimens, using a multipurpose test system M42, was performed. The data were subjected to the ttest. Results. The myenteric ganglia of very old humans contains an empty space, i.e. the respective parts of ganglia show a decreased number of neuron as compared to younger population. The average number of neuron per cm2 of the duodenum in the youngest people (20-44 years was 69,370 ± 1,750.00, in the people aged 45-64 years 69,211 ± 1,573.33, and in the oldest persons (65-84 years 57,951 ± 1,291.52. The loss of neurons in the oldest persons was 16.46%. The applied statistic test demonstrated a significant difference between the observed groups (p < 0.0001. Conclusion. Aging does not induce changes in size and surface of neurons in the ganglia, but it decreases the number of neurons. The nerve structures in the elderly are partly emptied of bodies of nerve cells (“empty ganglions”, which indicates the existence of changed myenteric ganglia in the duodenum. These changes could be related to the duodenum motility disorder associated with aging.

    Full Text Available Cholecystokinin (CCK influences gastrointestinal motility, by acting on central and peripheral receptors. The aim of the present study was to determine whether CCK has any effect on isolated duodenum longitudinal muscle activity and to characterize the mechanisms involved. Isolated segments of the rat proximal duodenum were mounted for the recording of isometric contractions of longitudinal muscle in the presence of atropine and guanethidine. CCK-8S (EC50: 39; 95% CI: 4.1-152 nM and cerulein (EC50: 58; 95% CI: 18-281 nM induced a concentration-dependent and tetrodotoxin-sensitive relaxation. Nomeganitro-L-arginine (L-NOARG reduced CCK-8S- and cerulein-induced relaxation (IC50: 5.2; 95% CI: 2.5-18 µM in a concentration-dependent manner. The magnitude of 300 nM CCK-8S-induced relaxation was reduced by 100 µM L-NOARG from 73 ± 5.1 to 19 ± 3.5% in an L-arginine but not D-arginine preventable manner. The CCK-1 receptor antagonists proglumide, lorglumide and devazepide, but not the CCK-2 receptor antagonist L-365,260, antagonized CCK-8S-induced relaxation in a concentration-dependent manner. These findings suggest that CCK-8S and cerulein activate intrinsic nitrergic nerves acting on CCK-1 receptors in order to cause relaxation of the rat duodenum longitudinal muscle.

Objective To analyze the clinicopathological characteristics of patients with resected duodenal carcinoids. Methods Twenty patients (12 females and 8 males were investigated. Their average age was 66.4 ± 5.8 years old (43 to 88 years old. The data corresponding to the clinical picture, diagnosis, treatment, and prognosis of patients with duodenal carcinoid tumors subjected to resection over a period of 18 years (1993-2011 were analyzed. Results The most common symptoms were dyspepsia (50% and epigastric pain (45% followed by weight loss (10% and vomiting (5%. Carcinoid syndrome was not observed in any patient. The lesion was located on the first part of the duodenum in 15 (75% patients, the second part in 4 (20% patients, and the third part in 1 (5% patient. The diagnosis of a carcinoid tumor was established through an endoscopic excision biopsy in 19 (95% patients and an histopathological examination of the surgical specimen in 1 (5% patient. The average tumor size was 1.1 cm ± 0.4 cm (0.3 cm to 6.0 cm. Nineteen (95% patients were initially treated by endoscopic resection of the duodenal lesion.

Proportions of Fusobacteria (p = 0.010, Bacteroidaceae (p = 0.015, Prevotellaceae (p = 0.022, and Clostridiales (p = 0.019 were significantly more abundant in healthy dogs. In contrast, specific bacterial genera within Proteobacteria, including Diaphorobacter (p = 0.044 and Acinetobacter (p = 0.040, were either more abundant or more frequently identified in IBD dogs. CONCLUSIONS/SIGNIFICANCE: In conclusion, dogs with spontaneous IBD exhibit alterations in microbial groups, which bear resemblance to dysbiosis reported in humans with chronic intestinal inflammation. These bacterial groups may serve as useful targets for monitoring intestinal inflammation.

    Despite wide belief that the duodenal Organ Injury Scale has been validated, this has not been reported in the published literature. Based on clinical experience, we hypothesize that the American Association for Surgery of Trauma Organ Injury Scale (AAST-OIS) for duodenal injuries can independently predict mortality. Our objectives were threefold: (1) describe the national profile of penetrating duodenal injuries, (2) identify predictors of morbidity and mortality, and (3) validate the duodenum AAST-OIS as a statistically significant predictor of mortality. Using the Abbreviated Injury Scale 2005 and International Classification of Diseases-9th Rev.-Clinical Modification (ICD-9-CM) E-codes, we identified 879 penetrating duodenal trauma patients from the National Trauma Data Bank between 2010 and 2014. We controlled patient-level covariates of age, biological sex, systolic blood pressure (SBP), Glasgow Coma Scale (GCS) score, pulse, Injury Severity Score (ISS), and Organ Injury Scale (OIS) grade. We estimated multivariable generalized linear mixed models to account for the nesting of patients within trauma centers. Our results indicated an overall mortality rate of 14.4%. Approximately 10% of patients died within 24 hours of admission, of whom 76% died in the first 6 hours. Patients averaged approximately five associated injuries, 45% of which involved the liver and colon. Statistically significant independent predictors of mortality were firearm mechanism, SBP, GCS, pulse, ISS, and AAST-OIS grade. Specifically, odds of death were decreased with 10 mm Hg higher admission SBP (13% decreased odds), one point higher GCS (14.4%), 10-beat lower pulse (8.2%), and 10-point lower ISS (51.0%). This study is the first to report the national profile of penetrating duodenal injuries. Using the National Trauma Data Bank, we identified patterns of injury, predictors of outcome, and validated the AAST-OIS for duodenal injuries as a statistically significant predictor of morbidity

    Full Text Available Abstract Background Chronic pancreatitis is an inflammatory disease which is characterized by an irreversible conversion of pancreatic parenchyma to fibrous tissue. Beside obstructive jaundice and pseudocyst formation, about half of the patients need surgical intervention due to untreatable chronic pain during the course of the disease. In most of the patients with chronic pancreatitis, the head of the pancreas is the trigger of the chronic inflammatory process. Therefore, resection of pancreatic head tissue must be the central part of any surgical intervention. However, it is unclear to which extent the surgical procedure must be radical in order to obtain a favourable outcome for the patients. Design A single centre randomized controlled, superiority trial to compare two techniques of duodenum preserving pancreatic head resection. Sample size: 65 patients will be included and randomized intraoperatively. Eligibility criteria: All patients with chronic pancreatitis and indication for surgical resection and signed informed consent. Cumulative primary endpoint (hierarchical model: duration of surgical procedure, quality of life after one year, duration of intensive care unit stay, duration of hospital stay. Reference treatment: Resection of the pancreatic head with dissection of the pancreas from the portal vein and transsection of the gland (Beger procedure. Intervention: Partial Resection of the pancreatic head without transsection of the organ and visualization of the portal vein (Berne procedure. Duration: September 2003-October 2007.

    Pancreas divisum (PD) represents a duct anomaly in the pancreatic head ducts, leading frequently leading to recurrent acute pancreatitis (rAP) or chronic pancreatitis (CP). Based on endoscopic retrograde cholangiopancreatography, pancreas divisum can be found in 1% to 6% of patients with pancreatitis. The correlation of this abnormality with pancreatic disease is an issue of continuing controversy. Because of the underlying duct anomalies and major pathomorphological changes in the pancreatic head, duodenum-preserving pancreatic head resection (DPPHR) offers an option for causal treatment. Thirty-six patients with pancreatitis caused by PD were treated surgically. Thirty patients suffered from CP, 6 from rAP. The mean duration of the disease was 47.5 and 49.8 months, respectively. The age at the time of surgery was 39.2 years in the CP group, and 27.6 years in the rAP group. Median hospitalization since diagnosis was 18.8 weeks for CP patients and 24.6 weeks for rAP patients. Previous procedures performed in these patients included endoscopic papillotomy (30%), duct stenting (14%), and surgical treatment (17%). The median preoperative pain score was 8 on a visual analog scale. According to the classification of pancreas divisum, 10 patients demonstrated a complete PD, 25 had a functionally incomplete PD, and 1 had a dorsal duct type. The pain status as well as the endocrine (oral glucose tolerance test) and exocrine (pancreolauryl test) function were evaluated preoperatively and early and late postoperatively with a median follow-up time of 39.3 months. There was no operative-related mortality. The follow-up was 100%; 4 patients died (1 from suicide, 1 from cardiac arrest, and 2 from cancer of the esophagus). Fifty percent of the patients were completely pain-free, 31% had a significant reduction of pain with a median pain score of 2 (P pancreatitis with a need for hospitalization. DPPHR reduced pain and preserved the endocrine function in the majority of patients

    Optimizing peak bone mass in early life is one of key preventive strategies against osteoporosis. Fructus ligustri lucidi (FLL), the fruit of Ligustrum lucidum Ait., is a commonly prescribed herb in many kidney-tonifying traditional Chinese medicinal formulas to alleviate osteoporosis. Previously, FLL extracts have been shown to have osteoprotective effect in aged or ovariectomized rats. In the present study, we investigated the effects of FLL ethanol extract on bone mineral density (BMD) and mechanical properties in growing male rats and explored the underlying mechanisms. Male weaning Sprague-Dawley rats were randomized into four groups and orally administrated for 4 months an AIN-93G formula-based diet supplementing with different doses of FLL ethanol extract (0.40, 0.65, and 0.90 %) or vehicle control, respectively. Then calcium balance, serum level of Ca, P, 25(OH)2D3, 1,25(OH)2D3, osteocalcin (OCN), C-terminal telopeptide of type I collagen (CTX-I), and parathyroid hormone, bone microarchitecture, and calcium absorption-related genes expression in duodenum and kidney were analyzed. The results demonstrated that FLL ethanol extract increased BMD of growing rats and improved their bone microarchitecture and mechanical properties. FLL ethanol extract altered bone turnover, as evidenced by increasing a bone formation maker, OCN, and decreasing a bone resorption maker, CTX-I. Intriguingly, both Ca absorption and Ca retention rate were elevated by FLL ethanol extract treatment, possibly through the mechanisms of up-regulating the transcriptions of calcitropic genes in kidney (1α-hydroxylase) and duodenum (vitamin D receptor, calcium transporter calbindin-D9k, and transient receptor potential vanilloid 6). In conclusion, FLL ethanol extract increased bone mass gain and improved bone properties via modulating bone turnover and up-regulating calcium absorption-related gene expression in kidney and duodenum, which could then activate 1,25(OH)2D3-dependent calcium

    Full Text Available ABSTRACT The objective of this study was to determine the effect of dietary symbiotic supplementation on the growth performance and duodenum histological parameters of quail reared in different flooring systems. A total of 160 mixed-sex healthy quail (47±0.32 g aged 14 days were used in a 2 × 2 factorial experimental design with four replicates, each including five males and five females. Two flooring systems (wire floor as control and wood shavings bedding and two dietary treatments (symbiotic supplementation and no supplementation were tested. Birds were transferred to four-tier cages for the trial. Each kilogram of the commercial diet included 224 g crude protein and 3,080 kcal metabolizable energy. The experiment lasted 21 days. Daily weight gain and gastrointestinal tract weight were statistically higher in the wood shavings and wood shavings + symbiotic-supplemented groups than in control group. Villi length was higher in the wood shavings + symbiotic and symbiotic-supplemented groups than in control and wood shavings groups. The wood shavings groups had longer villi than control group. Villi width was higher in wood shaving + symbiotic-supplemented groups compared with the other treatment groups. The litter system of wood shavings and symbiotic supplementation provide better growth performance to quail by developing their duodenum histomorphological parameters and digestive tract.

    A partial pancreaticogastrodudenectomy was performed on a 66-year old man with type 2 diabetes mellitus because of an invasive, moderately differentiated adenocarcinoma in the head of the pancreas. In the adjacent grossly normal tissue of the uncinate process, there was a massive proliferation of pancreatic polypeptide (PP) cells confined to this region and showed invasive pattern. Strikingly, in the heaped area of his duodenum, there was a strikingly large number of PP, glucagon, a few insulin cells in a mini-islet-like patterns composed of glucagon and insulin cells. Among the etiological factors, the possible long-lasting effects of the GLP-1 analog, with which the patient was treated, are discussed. This is the first report in the literature of both the coexistence of a pancreatic adenocarcinoma and invasive PPoma and the occurrence of PP and insulin cells in human duodenal mucosa.

    The aim of the present experiment was to ascertain if a daily niacin supplementation of 6 g/cow to lactating dairy cow diets can compensate for the decrease in rumen microbial fermentation due to a negative rumen nitrogen balance (RNB). A total of nine ruminally and duodenally fistulated lactating multiparous German Holstein cows was used. The diets consisted of 10 kg dry matter (DM) maize silage and 7 kg DM concentrate and differed as follows: (i) Diet RNB- (n = 6) with energy and utilisable crude protein (CP) at the duodenum (uCP) according to the average requirement of the animals, but with a negative RNB (-0.41 g N/MJ metabolisable energy [ME]); (ii) Diet RNB0 (n = 7) with energy, uCP, and RNB (0.08 g N/MJ ME) according to the average requirement of the animals; and (iii) Diet NA (nicotinic acid; n = 5), which was the same diet as RNB-, but supplemented with 6 g niacin/d. The negative RNB affected the rumen fermentation pattern and reduced ammonia content in rumen fluid and the daily duodenal flows of microbial CP (MP) and uCP. Niacin supplementation increased the apparent ruminal digestibility of neutral detergent fibre. The efficiency of microbial protein synthesis per unit of rumen degradable CP was higher, whereby the amount of MP reaching the duodenum was unaffected by niacin supplementation. The number of protozoa in rumen fluid was higher in NA treatment. The results indicated a more efficient use of rumen degradable N due to changes in the microbial population in the rumen when niacin was supplemented to diets deficient in RNB for lactating dairy cows.

    The purpose of this study was to investigate the influence of gastric emptying patterns, surfactants, and dosage form on the supersaturation of a poorly soluble weakly basic drug, dipyridamole, using an in vitro model mimicking the dynamic environment of the upper gastrointestinal tract, and, furthermore, to evaluate the usefulness of this model in establishing correlations to in vivo bioavailability for drugs with solubility/dissolution limited absorption. A simulated stomach duodenum model comprising four compartments was used to assess supersaturation and precipitation kinetics as a function of time. It integrates physiologically relevant fluid volumes, fluid transfer rates, and pH changes of the upper GI tract. Monoexponential gastric emptying patterns simulating the fasted state were compared to linear gastric emptying patterns simulating the fed state. The effect of different surfactants commonly used in oral preparations, specifically, sodium lauryl sulfate (SLS), poloxamer-188, and polysorbate-80, on dipyridamole supersaturation was investigated while maintaining surface tension of the simulated gastric fluids at physiological levels and without obtaining artificial micellar solubilization of the drug. The supersaturation behavior of different dose strengths of dipyridamole was explored. Significant levels of dipyridamole supersaturation were observed in the duodenal compartment under all the different in vivo relevant conditions explored. Dipyridamole supersaturation ratios of up to 11-fold have been observed, and supersaturation has been maintained for up to 120 min. Lower duodenal concentrations of dipyridamole were observed under linear gastric emptying patterns compared to mononexponential gastric emptying. The mean duodenal area under concentration-time curves (AUC60min) for the dipyridamole concentration profile in the duodenal compartment is significantly different for all the surfactants explored (P stomach duodenum model can provide a reliable and

    Nutritional and metabolic complications can develop after Roux-en-Y gastric bypass (RYGB) when there is an exaggerated response to the anatomical and functional changes or when there is inadequate nutritional supplementation. Severe malnutrition is rare, but deficiencies of vitamin B12, iron, calcium and thiamin, metabolic bone disease and gallstones are common after RYGB. Shortage of vitamin B12, iron, calcium and also cholelithiasis are caused at least partially by excluding the duodenum and proximal jejunum from food transit. We designed a new procedure, with the maintenance of the duodenum and proximal jejunum in the gastrointestinal transit through interposition of jejunal loop, as a primary operation to prevent such deficiencies or as corrective surgery for severe malnutrition after RYGB with failure in responding to conservative treatment. Complicações nutricionais e metabólicas podem se desenvolver após a derivação gástrica em Y de Roux (DGYR) quando há uma resposta exagerada às mudanças anatômicas e funcionais ou quando há suplementação nutricional inadequada. A desnutrição grave é rara, mas deficiências de vitamina B12, ferro, cálcio e tiamina, doença óssea metabólica e cálculos biliares são comuns após a DGYR. Dessas deficiências mencionadas, a de vitamina B12, de ferro, de cálcio e também a colelitíase, são causadas, ao menos parcialmente, pela exclusão do duodeno e jejuno proximal. Um novo procedimento com a manutenção do duodeno e do jejuno proximal no trânsito gastrointestinal, mediante interposição de alça jejunal, foi idealizado como operação primária para prevenir essas deficiências ou como cirurgia corretiva de desnutrição grave após DGYR com falha na resposta a exaustivas tentativas de tratamento conservador.

    Full Text Available Primary pure squamous cell carcinoma (SCC of the gallbladder is an exceptionally rare type of tumor that comprises only 1% of all gallbladder cancer. SCC of the gallbladder portends a worse prognosis than the more common adenocarcinoma variant because of its aggressive invasion to local structures and because it is often diagnosed at an advanced stage. Owing to its rarity, diagnosis and management can be challenging. Herein, we present the case of a 75-year-old female complaining of abdominal pain, nausea, and vomiting. Computed tomography and ultrasonography results of the abdomen were consistent with acute cholecystitis and cholelithiasis. Histologic evaluation of the resected mass revealed a malignant tumor with prominent keratinization, confirming the diagnosis of an invasive primary pure SCC of the gallbladder. Microscopic examination showed direct infiltration to the liver, duodenum, and stomach. This case report describes the hospital course of a patient with SCC of the gallbladder and suggests that gallbladder cancer should be considered as part of the differential diagnosis in elderly patients presenting with acute cholecystitis. In addition, this article will review existing literature to examine the utility of different diagnostic techniques and treatment modalities available in the management of gallbladder cancer.

    Pylorus-preserving pancreaticoduodenectomy (PPPD) and duodenum-preserving pancreatic head resection (DPPHR) are important treatment options for patients with chronic pancreatitis. This meta-analysis was undertaken to compare the long-term outcomes of DPPHR versus PPPD in patients with chronic pancreatitis. A systematic literature search was conducted using Embase, MEDLINE, Cochrane, and PubMed databases on all studies published between January 1991 and January 2013 reporting intermediate and long-term outcomes after DPPHR and PPPD for chronic pancreatitis. Long-term outcomes of interest were complete pain relief, quality of life, professional rehabilitation, exocrine insufficiency, and endocrine insufficiency. Other outcomes of interest included perioperative morbidity and length of stay (LOS). Ten studies were included comprising of 569 patients. There was no significant difference in complete pain relief (P = 0.24), endocrine insufficiency (P = 0.15), and perioperative morbidity (P = 0.13) between DPPHR and PPPD. However, quality of life (P insufficiency (P = 0.005), and LOS (P = 0.00001) were significantly better for patients undergoing DPPHR compared with PPPD. In conclusion, there is no significant difference in endocrine insufficiency, postoperative pain relief, and perioperative morbidity for patients undergoing DPPHR versus PPPD. Improved intermediate and long-term outcomes including LOS, quality of life, professional rehabilitation, and preservation of exocrine function make DPPHR a more favorable approach than PPPD for patients with chronic pancreatitis.

    Therapy with non-steroidal anti-inflammatory drugs (NSAIDs) is a diffcult task. Good anti-inflammatory effect increases the risk of gastrointestinal complications with a frequency of 10-50%. The risk further increases with age (above 60-70 yr), the history of ulcer disease concomitant intake of acetylsalicylic acid, anticoagulants, and glucocorticosteroids. Long-term antisecretory therapy with proton pump inhibitors, e.g., esomeprazole, was shown to be an effective prophylactic tool. This drug maintains the intragastric pH value above 4 for 15 hr on the average. The risk of erosive and ulceraive lesions in the stomach and duodenum significantly decreases by selective cyclooxygenase-2 inhibitors, e.g., coxibs, that however increase the risk of thrombotic cardiovascular complications. The author proposes recommendations on the use of NSAIDs in the patients at risk of serious gastrointestinal and cardiovascular pathology. Naproxen in combination with proton pitmp inhibitors is the drug of choice among NSAIDs. Vimovo is a fixed combination of naproxen and esomeprazole. Results of comparative studies on the efficacy of vimovo and celecoxib are presented along with the data on the safety of this. combination compared with that of naproxen monotherapy

    Sphincter of Oddi dysfunction is one of the most important symptoms in post-cholecystectomy syndrome. Using either electrical or mechanical stimulation and retrogradely transported neuronal dyes, it has been demonstrated that there are direct neural pathways connecting gall bladder and the sphincter of Oddi in the Australian opossum and the golden hamster. In the present study, we employed whole-mount immunohistochemistry staining to observe and verify that there are two different plexuses of the extrahepatic biliary tract in Suncus murinus. One, named Pathway One, showed a fine, irregular but dense network plexus that ran adhesively and resided on/in the extrahepatic biliary tract wall, and the plexus extended into the intrahepatic area. On the other hand, named Pathway Two, exhibiting simple, thicker and straight neural bundles, ran parallel to the surface of the extrahepatic biliary tract and passed between the gall bladder and duodenum, but did not give off any branches to the liver. Pathway Two was considered to involve direct bidirectional neural connections between the duodenum and the biliary tract system. For the first time, morphologically, we demonstrated direct neural connections between gall bladder and duodenum in S. murinus. Malfunction of the sphincter of Oddi may be caused by injury of the direct neural pathways between gall bladder and duodenum by cholecystectomy. From the viewpoint of preserving the function of the major duodenal papilla and common bile duct, we emphasize the importance of avoiding kocherization of the common bile duct so as to preserve the direct neural connections between gall bladder and sphincter of Oddi. © 2015 Blackwell Verlag GmbH.

    To develop a new medical technology for the spa-and-health resort-based treatment of the patients presenting with frequently recurring erosive and ulcerative lesions in the oesophagus, stomach, and duodenum in the phase of subsiding exacerbation. A total of 100 patients presenting with frequently recurring erosive and ulcerative lesions in the oesophagus, stomach, and duodenum in the phase of subsiding exacerbation were available for the examination that included detailed investigations of the clinical picture, characteristics of the immune status, and psychological testing before and after a course of the spa-and-health resort-based treatment. The effectiveness of two therapeutic modalities was evaluated. One of them (control) prescribed to 50 patients consisted of standard antiulcer pharmacotherapy in combination with Essentuki Novaya drinking mineral water and carbon dioxide mineral baths, the other given to 50 patients included radon baths instead of carbon dioxide mineral baths. The combined application of drinking mineral waters, radon baths, and standard antiulcer pharmacotherapy produced the most conspicuous clinical effect in the framework of spa-and-health resort-based rehabilitation of the patients presenting with frequently recurring erosive and ulcerative lesions in the oesophagus, stomach, and duodenum in the phase of subsiding exacerbation as confirmed by positive dynamics of their psychoemotional status in 97.7% of the cases, regression of pain syndrome (91.5%), and improvement of humoral and cellular immunity (94%). An important result of the spa-and-health resort-based rehabilitation is the intensification of the reparative processes in gastroduodenal mucosa responsible for the healing of ulcers and erosions in 94.7% of the patients. The spa-and-health resort-based rehabilitation is a pathogenetically sound and efficacious approach to the management of the patients presenting with frequently recurring erosive and ulcerative lesions in the

    To evaluate effects of injection with a nonsteroidal anti-inflammatory drug (NSAID) followed by oral administration of an NSAID on the gastrointestinal tract (GIT) of healthy dogs. 6 healthy Walker Hounds. In a randomized, crossover design, dogs were administered 4 treatments consisting of an SC injection of an NSAID or control solution (day 0), followed by oral administration of an NSAID or inert substance for 4 days (days 1 through 4). Treatment regimens included carprofen (4 mg/kg) followed by inert substance; saline (0.9% NaCl) solution followed by deracoxib (4 mg/kg); carprofen (4 mg/kg) followed by carprofen (4 mg/kg); and carprofen (4 mg/kg) followed by deracoxib (4 mg/kg). Hematologic, serum biochemical, and fecal evaluations were conducted weekly, and clinical scores were obtained daily. Endoscopy of the GIT was performed before and on days 1, 2, and 5 for each treatment. Lesions were scored by use of a 6-point scale. No significant differences existed for clinical data, clinicopathologic data, or lesion scores in the esophagus, cardia, or duodenum. For the gastric fundus, antrum, and lesser curvature, an effect of time was observed for all treatments, with lesions worsening from before to day 2 of treatments but improving by day 5. Sequential administration of NSAIDs in this experiment did not result in clinically important gastroduodenal ulcers. A larger study to investigate the effect of sequential administration of NSAIDs for longer durations and in dogs with signs of acute and chronic pain is essential to substantiate these findings.

    A ration of 600 g chopped hay and 150 g ground sorghum is given twice daily to sheep fitted with a rumen cannula and a duodenal reentrant cannula. /sup 141/Ce flow rate at the duodenum and in the feces is compared to flow rate of stained hay particles after ingestion of a single labelled meal. After an adaptation period during which both daily meals are labelled, variations in /sup 141/Ce concentration are then measured in the duodenal and fecal dry matter. The tracer is used to estimate dry mater digestibility indirectly. Duodenal data show that the mean retention time of /sup 141/Ce in the rumen is about 15% less than that of stained particles. The meal after the radioactive one momentarily depresses /sup 141/Ce excretion rate while it accelerates that of the stained particles. Mean retention time in the whole gastro-intestinal tract of a meal of 600 g chopped hay 150 g ground sorghum is 40.4+-3.8 h or 32.4+-3.7 h, depending on whether stained particles or /sup 141/Ce is used. All the /sup 141/Ce ingested is recovered in the feces. Mean recovery of /sup 141/Ce in the feces excreted during 200 hours after dosage is 100.2+-5.0%. After a period of adaptation where all meals are radioactive, feces of 2 sheep are sampled either by total collection or directly in the rectum. Dry matter digestibility does not differ whether calculated from total collection or by the indirect method using /sup 141/Ce.

    To determine whether cholecystokinin secretion is regulated by endogenous somatostatin, somatostatin deficiency was induced in vivo with cysteamine (250 mg/kg body wt, IV) or anti-somatostatin antiserum in anaesthetized rats and in vitro with cysteamine (30 micrograms/mL) in a rat duodenum-incubation system. Cholecystokinin secretion was assessed in vivo by measuring amylase in duodenal perfusates collected at 10-minute intervals for 1 hour and in vitro by a carboxy-terminal radioimmunoassay. Cysteamine induced a marked decrease in duodenal immunoreactive somatostatin both in vivo (50%) and in vitro (60%). The rate of amylase secretion increased from 9.7 +/- 2.1 U (mean +/- SE) to 28.0 +/- 4.8 U at 20 minutes (P less than 0.001). The cholecystokinin-receptor antagonist CR-1392 abolished amylase response for 30 minutes, whereas the more potent antagonists Asperlicin (18.0 mg/kg body wt, IV) and L-364,718 (0.25 mg/kg body wt, IV) caused prolonged blockade. The rate of amylase secretion in gastrectomized animals increased from 7.2 +/- 2.0 U to 15.0 +/- 2.2 U 20 minutes after cysteamine administration (P less than 0.01), indicating that the effect was not due to the presence of gastrin. In vitro, cysteamine caused a nearly fourfold increase in cholecystokinin secretion compared with controls (63.1 +/- 4.9 vs. 15.2 +/- 3.7, respectively; P less than 0.001). In vivo immunoneutralization of circulating somatostatin with a high-affinity and high-capacity antiserum produced no significant change in the rate of amylase secretion. These results suggest that cholecystokinin secretion is tonically inhibited by somatostatin and that this effect is mediated by locally secreted (paracrine) but not by circulating somatostatin

Therefore, systemic therapy is still challenging, and the curative resection of localized or locally advanced RCC with sarcomatoid differentiation is very important. Axitinib is a potent and selective second-generation vascular endothelial growth factor receptor tyrosine kinase inhibitor with improved safety and tolerability. Axitinib is generally recommended as second-line therapy for advanced RCC because the phase III axitinib versus sorafenib in advanced RCC (AXIS trial demonstrated that it achieved longer progression-free survival than sorafenib in patients with metastatic RCC after failure of an approved first-line regimen. Methods: We present a 73-year-old man who had a large (13 cm in diameter right RCC with sarcomatoid differentiation that directly invaded the duodenum and inferior vena cava. The patient presented with gastrointestinal bleeding, was unable to eat solid food, and had become emaciated. Thus, his classification was poor risk with anemia, hypercalcemia, and poor performance status, according to the Memorial Sloan-Kettering Cancer Center criteria. He seemed unlikely to survive if radical nephrectomy, cavotomy with thrombectomy, and pancreatoduodenectomy were performed. To reduce the tumor burden and potential operative complications, we administered axitinib as first-line neoadjuvant therapy. Results: Six weeks of treatment reduced the tumor burden without causing severe toxicities. Subsequently, radical right nephrectomy, cavotomy

    Dogs are one of the most commonly used non-rodent species in toxicology studies and are known to have basal stomach pH ranging from 2 to 7 in the fasted state. Thus absorption and resulting plasma exposure of weakly basic compounds administered as crystalline suspensions to dogs are often variable. LY2157299 is a potent and selective transforming growth factor (TGF)-beta receptor type 1 kinase (TGF-βRI) inhibitor that displayed variable absorption in early dog studies. This molecule is a weakly basic Biopharmaceutics Classification System (BCS)Class II compound, and depends on the rate and extent of dissolution to drive oral absorption. An artificial stomach and duodenum (ASD) dissolution model was utilized to evaluate potential effect of gastric pH on the absorption of suspension and buffered solution formulations. GastroPlus™ was also employed to predict the magnitude of gastric pH changes on LY2157299 absorption. The ASD experiments demonstrated that administration of a buffered acidic solution could improve the potential for absorption by normalizing gastric pH and enabling supersaturation in the duodenum. GastroPlus™ modeling suggested that direct modulation of gastric pH could lead to marked changes in bioavailability. Pharmacokinetic experiments were conducted in dogs to evaluate the effect of gastric pH modification on plasma exposure. The data were qualitatively consistent with the predictions.

    Three prospective randomised studies were conducted to compare pancreatoduodenectomy (PD) with duodenum-preserving pancreatic head resection (DPPHR) in patients suffering from chronic pancreatitis (cP). In these three series, the superiority of the duodenum-preserving technique with regard to quality of life (QOL) and pain relief has been demonstrated. Long-term follow-up investigations have not been published so far. The present paper reports on a 5-year follow-up study of a prospective, non-randomised trial comparing classic Whipple procedure (PD) with Beger DPPHR. Seventy patients were initially enrolled in this study. Fifty-one patients were left for the present long-term outcome analysis (PD, n = 24; DPPHR, n = 27). The follow-up included the following parameters: QOL, pain intensity, endocrine and exocrine function, and body mass index (BMI). The median follow-up was 63.5 (range 56-67) months. Two patients in the DPPHR group and none in the PD group underwent a re-operation. The QOL scores of the relevant symptom scales (nausea, pain, diarrhoea) and functional parameters (physical status, working ability, global QOL) were significantly better in the DPPHR group than in the PD group. Pain intensity as self-assessed by the patients was less pronounced in the DPPHR group (P Whipple procedure in terms of QOL and pain intensity as self-assessed by the patients.

    Complex fistulas of the duodenum and biliary tree are severe complications of gastric surgery. The association of duodenal and major biliary fistulas occurs rarely and is a major challenge for treatment. They may occur during virtually any kind of operation, but they are more frequent in cases complicated by the presence of difficult duodenal ulcers or cancer, with a mortality rate of up to 35%. Options for treatment are many and range from simple drainage to extended resections and difficult reconstructions. Conservative treatment is the choice for well-drained fistulas, but some cases require reoperation. Very little is known about reoperation techniques and technical selection of the right patients. We present the case of a complex iatrogenic duodenal and biliary fistula. A 42-year-old Caucasian man with a diagnosis of postoperative peritonitis had been operated on 3 days earlier; an antrectomy with a Roux-en-Y reconstruction for stenotic peptic disease was performed. Conservative treatment was attempted with mixed results. Two more operations were required to achieve a definitive resolution of the fistula and related local complications. The decision was made to perform a pancreatoduodenectomy with subsequent reconstruction on a double jejunal loop. The patient did well and was discharged on postoperative day 17. In our experience pancreaticoduodenectomy may be an effective treatment of refractory and complex iatrogenic fistulas involving both the duodenum and the biliary tree.

  18. Stimulation of a Cd-binding protein, and inhibition of the vitamin D-dependent calcium-binding protein, by zinc or cadmium in organ-cultured embryonic chick duodenum

    Embryonic chick duodenum maintained in organ culture responds to 1 α,25-dihydroxy vitamin D 3 in the culture medium by de novo synthesis of a specific calcium-binding protein (CaBP). The addition of Cd 2+ (3-5 x 10 -5 M) or Zn 2+ (10 -5 -10 -4 M) to the medium inhibited CaBP, but stimulated biosynthesis of a Cd-binding protein (CdBP). CdBP in duodenal homogenate supernatants was assessed in two ways: first, by its 109 Cd-binding activity ( 109 CdBA) using a competitive ion exchange procedure; and, second, by the extent of [ 35 S]-cystine incorporation into a specific peak or band after gel filtration or analytical polyacrylamide disc gel electrophoresis, respectively. Regardless of whether cadmium- or zinc-stimulated, the 35 S-labeled CdBP - the only protein significantly labeled under the conditions employed - migrated identically upon gel filtration and electrophoresis, and comigrated with purified chick liver Cd-metallothionein. Neither actinomycin D nor α-amanitin, in concentrations sufficient to severely inhibit CaBP, significantly reduced CdBP production. However, cycloheximide did inhibit either Cd 2+ - or Zn 2+ -stimulated CdBP by about 50% at an inhibitor concentration which abolished CaBP. The inhibitor studies, coupled with the observations of extensive incorporation of [ 35 S]cystine into CdBP, suggest that the metals stimulated biosynthesis by a mechanism operating at the translational level. The organ-cultured duodenum seems well suited for studies of the regulation of CdBP biosynthesis especially since it responds predictably to the steroid hormone, 1α,25-dihydroxy vitamin D 3 , in the induction of another specific protein, CaBP, at the transcriptional level. The biosynthesis of CaBP thus may serve as a convenient control in studies of CdBP production under various experimental conditions

    Following resection of the head of the pancreas while preserving the duodenum a gastrointestinal haemorrhage was localised by red blood cells labeled in vivo with technetium-99m. The previously performed endoscopy and angiography were normal. The haemorrhage in the region of the pancreaticojejunal anastomosis was confirmed intraoperatively. If intermittent bleedings are suspected, scintigraphy should be performed as a routine measure besides endoscopy and angiography. (orig.).

    To evaluate the short and long term outcomes of duodenum preserving pancreatic head resection (DPPHR) procedures in the treatment of painful chronic pancreatitis. A systematic literature search was performed to identify all comparative studies evaluating long and short term postoperative outcomes (pain relief, morbidity and mortality, pancreatic exocrine and endocrine function). Five published studies fulfilled the inclusion criteria including 1 randomized controlled trial comparing the Beger and Frey procedure. In total, 323 patients underwent surgical procedures for chronic pancreatitis, including Beger (n = 138) and Frey (n = 99), minimal Frey (n = 32), modified Frey (n = 25) and Berne's modification (n = 29). Two studies comparing the Beger and Frey procedure were entered into a meta-analysis and showed no difference in post-operative pain (RD = -0.06; CI -0.21 to 0.09), mortality (RD = 0.01; CI -0.03 to 0.05), morbidity (RD = 0.12; CI -0.00 to 0.24), exocrine insufficiency (RD = 0.04; CI -0.10 to 0.18) and endocrine insufficiency (RD = -0.14 CI -0.28 to 0.01). All procedures are equally effective for the management of pain for chronic pancreatitis. The choice of procedure should be determined by other factors including the presence of secondary complications of pancreatitis and intra-operative findings. Registration number CRD42015019275.

    One thousand five hundred and eighty-three patients who were x-rayed for dyspepsia showed varioliform erosions in 15.3%. Men had an incidence of 9.8%, almost twice as common as in women (5.5%). Mucosal polyps, usually of the hyperplastic type, occurred in 2.4%. 15% of patients with gastric ulcers and 16% of patients with duodenal ulcers had varioliform erosions. On the other hand, amongst patients with erosions, 11% had gastric ulcers and 8.3% duodenal ulcers. The definitions of erosion which have been given in the literature are partly contradictory, and are discussed. Varioliform erosions, also known as complete erosions, may be acute or chronic. They are the third most common cause of bleeding from the upper gastrointestinal tract. With modern radiological methods of examining the stomach, they are no longer a rare finding. 5 figs.

    Full Text Available Trolox is a hydrophilic analogue of vitamin E and a free radical scavenger. Ethanol diminishes the amplitude of spontaneous contractions and acetylcholine (ACh-induced contractions in rabbit duodenum. The aim of this work was to study the effect of Trolox on the alterations induced by ethanol on contractility and lipid peroxidation in the duodenum. The duodenal contractility studies in vitro were carried out in an organ bath and the levels of malondialdehyde and 4-hydroxyalkenals (MDA+4-HAD were measured by spectrophotometry. Trolox increased the reduction induced by ethanol on the amplitude of spontaneous contractions in longitudinal muscle but not in circular muscle. Trolox 4 mM decreased the effects of ethanol on ACh-induced contractions and on MDA+4-HDA concentrations. We conclude that Trolox might prevent oxidative stress induced by ethanol in the duodenum.El Trolox es un análogo hidrofílico de la vitamina E y un agente que secuestra radicales libres.

    The small intestinal epithelium is continously renewed through a balance between cell division and cell loss. How this balance is achieved is uncertain. Thus, it is unknown to what extent programmed cell death (PCD) contributes to intestinal epithelial cell loss. We have used a battery...... of techniques detecting the events associated with PCD in order to better understand its role in the turnover of the intestinal epithelium, including modified double- and triple-staining techniques for simultaneously detecting multiple markers of PCD in individual cells. Only a partial correlation between TUNEL...... positivity for DNA fragmentation, c-jun phosphorylation on serine-63, positivity for activated caspase-3 and apoptotic morphology was observed. Our results show that DNA fragmentation does not invariable correlate to activation of caspase-3. Moreover, many cells were found to activate caspase-3 early...

    Full Text Available Primary (AL amyloidosis of the gastrointestinal tract is relatively rare, and symptomatic amyloidosis of the stomach is even more seldom. We present the case of a patient who was referred to upper endoscopy because of weight loss, nausea, and vomiting. Large areas of intramucosal hemorrhages were seen, and biopsies resulted in profuse bleeding stopped with endoscopic clips. The biopsies showed amyloid depositions and further workup revealed that the patient also had cardiac and neuropathic involvements. The patient started treatment with dexamethasone, melphalan and bortezomib. After treatment was started the nausea and epigastric discomfort improved, and a reduction in the biochemical markers troponin T, NT-proBNP, and M-component was observed. Gastric amyloidosis is rarely seen at upper endoscopy in patients without a previously established diagnosis, but the unusual endoscopic findings and bleeding tendency after biopsy should be kept in mind by gastroenterologists.

    Case presentation: The patient is a forty six years old man. He complained of frequent colic pain in left upper quadrant of abdomen for two months before admitting to the hospital. The pain resolved spontaneously after a few hours. This situation almost has been repeated every week. The patient had severe repeated melena and faint for two weeks. As soon as the patient was entered the Sina Hospital in 2012, supportive care was started. Then upper gastrointestinal endoscopy was performed for him and the bleeding point was detected. Also abdominal and pelvic computed tomography with oral and intravenous contrast was done. Finally the patient was operated on tumor diagnosis in duodenal area according to classic Whipple procedure. Conclusion: Gastrointestinal bleeding is the most common symptom of gastrointestinal stromal tumors. The bleeding is minimal and chronic. It will be progress to sudden and severe bleeding. Diagnosis is done by upper gastrointestinal endoscopy and biopsy. The large tumors with high mitotic

After the radiological examination, animals were necropsy for confirmation of the radiological findings, and the radiographs were the absence of the normal anatomy variations inspected and described by an experienced radiologist. RESULTS: All the radiographs produced achieved satisfactory results in terms of position, exposure, location and quality. The upper esophageal sphincter (UES was identified in the esophagus at the nerve C2, the lower esophageal sphincter (LES was identified between spinal cord segments L1 and L2, the thoracic-abdominal junction was observed at T10, the esophageal-gastric junction (EGJ at T13-L1, with the abdominal portion in the epigastric region. The stomach was observed mostly in the epigastric region, left hypochondrium, left and mesogastric flank. The duodenum findings presented higher variation, with most findings identified in the epigastric region, right hypochondrium, right flank and mesogastric ileal fossa at T13-L5. CONCLUSION: Contrast radiology is useful and may be employed to assess the anatomy of the animal being studied. The experimental model described afforded to fully identify all organs investigated, as well as other occasional relevant findings. No anatomical anomalies in the subsequent necropsy, confirming the radiographic findings.OBJETIVO: Avaliar a anatomia normal de ratas Wistar e a

    A 32-month-old male common marmoset had a firm and white-colored mass in the duodenal wall. The cut surface was smooth and grayish white in color. Histologically, the mass consisted of a proliferation of spindle cells with an oval to spindle-shaped nucleus and scant eosinophilic cytoplasm in a loose myxoid or fibrotic background. Most of the lesion displayed no specific growth pattern whereas some of the cells concentrated around the vessels and created an onion-bulb structure. Additionally, marked inflammatory cellular infiltration, mainly eosinophils, was observed throughout the lesion. Immunohistochemically, the spindle cells were positive for vimentin, α-smooth muscle actin, fascin, and cyclin D1, and negative for S-100, factor VIII-related antigen, and c-kit. These histological and immunohistochemical features did not meet any differential diagnoses such as gastrointestinal stromal tumor, inflammatory myofibroblastic tumor, solitary fibrous tumor/hemangiopericytoma, smooth muscle tumor, schwannoma, and hemangiosarcoma. Collectively, the authors diagnosed the mass as a lesion that corresponded to an inflammatory fibroid polyp (IFP) in humans. IFP is defined as a mesenchymal proliferation composed of spindle stromal cells, small blood vessels, and inflammatory cells, particularly eosinophils, and is currently classified as a nonneoplastic lesion. To the best of our knowledge, this is the first case of spontaneous IFP in nonhuman primates.

    The duodenal and/or pancreatic lesions rarely occur during abdominal contusions, this, because of the deep and retroperitoneal position of the duodeno-pancreatic entity. These lesions occur mostly in the young adults and occur mostly on violent trauma, hence the high frequency of associated lesions. Their management is well codified and the prognosis depends on the degree of pancreatic damage. The authors reporting of 3 cases of duodenaland or post-traumatic lesion, in a retrospective study. The after therapeutic management necessitated a pre-operative reanimation, simple duodenal suturing in the 3 cases with relearning gastrotomy, alimentation jejenostomy and closing of thepyloric sphincter,with association of cholostomy in one of the cases. The pancreatic lesions of type contusion observed in 2 cases necessitated simple drainage of the pancreatic sector without resection. The evolution was favourable in 2 cases. One case of death was noted in a patient who developed acute pancreatis.

    The successful management of upper gastrointestinal (GI) bleeding requires identification of the source of bleeding and when this is achieved the bleeding can often be treated endoscopically. However, the identification of the bleeding can be challenging due to the location of the bleeding...... or technical aspects. Therefore it might be necessary to use other measures than endoscopy such as CT angiography. Duodenal diverticula is a rare cause of upper GI bleeding and can be challenging to diagnose as they often require specialised endoscopy procedures such as endoscopy with a side-viewing scope....... This case describes the first successful management of this rare condition with an upper GI endoscopy with a colonoscope and afterwards intravascular coiling....

    Arteriovenous malformation (AVM) of the pancreas is a rare condition. Most patients are asymptomatic or alternatively may present with a wide spectrum of symptoms. Traditionally, surgery has been considered the treatment of choice; however, alternative approaches, such as transcatheter embolization (TAE), may be proposed. We report a case of a 48-year-old man with a pancreatic head AVM, presenting with upper abdominal pain and slight anemia. The patient refused surgery and underwent TAE by means of ethylene-vinyl alcohol copolymer (EVOH). At 3 months follow-up, the patient was able to eat regularly, with no residual pain and no signs of anemia.

    The paper is based on the analysis of clinical, X-ray, and morphological studies in 74 patients with massive gastrointestinal hemorrhage. The paper presents the specific features of X-ray studies of patients with bleeding gastroduodenal ulcers. X-ray studies shout be twice performed in these patients. The first study is conducted if gastroscopic findings are unclear, the repeated one is carried out while assessing changes in disease regression. X-ray diagnosis of bleeding ulcers is determined by their sites and the nature of an ulcerous process. The X-ray diagnosis of chronic callous gastric ulcers accompanied by hemorrhage was based on the detection of two direct symptoms of a niche on the gastric outlines and configuration and an inflammatory mound on the gastric outline and configuration. That of chronic bleeding ulcers of the duodenal bulb is based not only on searches niche, but other signs of the disease - the deformed organ, and the magnitude of a periprocess. 10 refs., 5 figs

    The results of personal dosimetry confirm that one of the most exposed groups to the ionizing radiations is those of Radiologists who work with radioscopy of the digestive tract. However, the particular conditions of the exposition complicate the interpretation of the reading for the values obtained on the dosimeter. In order to improve such interpretation, it has done simultaneous measurements with the routine dosimeter and with thermoluminescent dosimeters (TLD) of lithium fluoride(LiF). It has selected eight places on the worker's body and located such dosimeters, so that the dose was integrated during thirty studies. It could verify that, if the dosimeter is located in agreement with the recommendations of the International Commission of Radiological Protection(ICRP), the reading overestimates in several times the dose in whole body(or effective dose). It has also considered that the amount of such procedures done by the radiologist is limited in this case, by the effective dose

    Brush border membrane vesicles were isolated from mucosal homogenates of duodena from normal, rachitic and vitamin D-treated rachitic chicks using a discontinuous sucrose gradient, and further purified by glycerol gradient centrifugation. In vitro uptake of 75Se-selenite by purified brush border membrane vesicles was studied using a rapid filtration technique. The time course of 75Se uptake was non-linear; rapid initial binding was followed by a gradual decrease in the rate of uptake until an equilibrium value was reached at 60-120 min. The initial binding at 36 s was not affected by selenite concentration in the incubation buffer, while the fractional rate of uptake between the 36 s and 2 min time periods was clearly lower with 1 mM Se than with 4-100 microM Se. 75Se uptake did not show any dependency on the external Na-gradient, nor could it be inhibited by other anions (arsenate, phosphate). Treatment of rachitic chicks either with cholecalciferol (500 Iu, 72 h) or with 1,25(OH)2-cholecalciferol (0.5 microgram given 16 h prior to isolation of the vesicles) significantly enhanced 75Se uptake. A threefold excess of mannitol in the outside buffer reduced 75Se uptake by vesicles from vitamin D-deficient and D-treated chicks 60% and 35% respectively, but had no effect on vesicles from vitamin D-treated chicks preloaded with 75Se. Neither saponin treatment nor excess cold selenite could release the label from the vesicles preloaded with 75Se. These data are compatible with the hypothesis that selenite easily crosses the brush border membrane into the intravesicular space and, once inside, is tightly bound by the membrane

    Bile components play a significant role in the absorption of dietary fat, by solubilizing the products of fat digestion. The absorption of poorly water-soluble drugs from the gastrointestinal tract is often enhanced by interaction with the pathways of fat digestion and absorption. These processes can enhance drug absorption. Thus, the phase behavior of bile components and digested lipids is of great interest to pharmaceutical scientists who seek to optimize drug solubilization in the gut lumen. This can be achieved by dosing drugs after food or preferably by formulating the drug in a lipid-based delivery system. Phase diagrams of bile salts, lecithin, and water have been available for many years, but here we investigate the association structures that occur in dilute aqueous solution, in concentrations that are present in the gut lumen. More importantly, we have compared these structures with those that would be expected to be present in the intestine soon after secretion of bile. Phosphatidylcholines are rapidly hydrolyzed by pancreatic enzymes to yield equimolar mixtures of their monoacyl equivalents and fatty acids. We constructed phase diagrams that model the association structures formed by the products of digestion of biliary phospholipids. The micelle-vesicle phase boundary was clearly identifiable by dynamic light scattering and nephelometry. These data indicate that a significantly higher molar ratio of lipid to bile salt is required to cause a transition to lamellar phase (i.e., liposomes in dilute solution). Mixed micelles of digested bile have a higher capacity for solubilization of lipids and fat digestion products and can be expected to have a different capacity to solubilize lipophilic drugs. We suggest that mixtures of lysolecithin, fatty acid, and bile salts are a better model of molecular associations in the gut lumen, and such mixtures could be used to better understand the interaction of drugs with the fat digestion and absorption pathway.

    Full Text Available Background. Duodenal Dieulafoy’s lesion (DL is a rare disease that may lead to lethal hemorrhage in the upper gastrointestinal tract. The best technique for endoscopic intervention still remains unclear. In the present study, we performed a retrospective analysis of cyanoacrylate injection versus hemoclip placement for treating bleeding DLs. Materials and Methods. We retrospectively analyzed eighteen patients from three medical centers between October 2008 and February 2016; six patients received cyanoacrylate injection, while hemoclips were placed in 12 patients during the upper gastrointestinal endoscopy. Results. All patients received first endoscopic examination and/or endotherapy within 12 hours of admission to hospital. No difference was observed in the primary hemostasis rate or the recurrent hemorrhage rate between the cyanoacrylate injection (CI group and the hemoclip placement (HP group, except that in one patient from the HP group melena was found three days after the first endotherapy. This patient received cyanoacrylate injection once again. Conclusion. Both cyanoacrylate injection and hemoclip placement are effective in treating duodenal DL, and neither of them causes significant side effects.

  4. Does lead use the intestinal absorptive pathways of iron? Impact of iron status on murine 210Pb and 59Fe absorption in duodenum and ileum in vivo

    International Nuclear Information System (INIS)

    Elsenhans, Bernd; Janser, Heinz; Windisch, Wilhelm; Schuemann, Klaus

    2011-01-01

    Highlights: → Absorption of 210 Pb increases much less than that of 59 Fe in murine duodena. → 210 Pb-absorption is almost equally high in murine duodenal and ileal segments. → 59 Fe absorption is much lower in ileal than in duodenal segments. → There must be an additional DMT1-independet pathway for intestinal Pb absorption. -- Abstract: Background: Human isotope studies and epidemiological trials are controversial as to whether lead absorption shares the absorptive pathways of iron and whether body lead content can be reduced by iron supplementation. Aim: To compare the impact of iron-deficiency on 59 Fe- and 210 Pb-absorption rates in duodenal and ileal segments. Methods: 59 Fe- and 210 Pb-absorption was determined in ligated duodenal and ileal segments from juvenile and adult iron-deficient and iron-adequate C57Bl6 wild-type mice (n = 6) in vivo at luminal concentrations corresponding to human exposure (Fe: 1 and 100 μmol/L; Pb: 1 μmol/L). Results and discussion: 59 Fe-absorption increased 10-15-fold in iron-deficient duodena from adult and adolescent mice. Ileal 59 Fe-absorption was 4-6 times lower than in iron-adequate duodena showing no adaptation to iron-deficiency. This in accordance to expectation as the divalent metal transport 1 (DMT1) shows low ileal expression levels. Juvenile 59 Fe-absorption was about twice as high as in adult mice. In contrast, duodenal 210 Pb-absorption was increased only 1.5-1.8-fold in iron-deficiency in juvenile and adult mice and, again in contrast to 59 Fe, ileal 210 Pb-absorption was as high as in iron-adequate duodena. Conclusions: The findings suggest a DMT1-independent pathway to mediate lead absorption along the entire small intestine in addition to DMT1-mediated duodenal uptake. Ileal lead absorption appears substantial, due the much longer residence of ingesta in the distal small intestine. Differences in lead-solubility and -binding to luminal ligands can, thus, explain the conflicting findings regarding the impact of iron-status on lead absorption. They need to be considered in future studies.

  5. Relationship of membrane-bound sulfhydryl groups to vitamin D-stimulated uptake of [75Se]Selenite by the brush border membrane vesicles from chick duodenum

    1990-01-01

    The uptake of selenite by purified brush border membrane vesicles isolated from duodena of rachitic or vitamin D-treated chicks was studied by using radioactive selenite and a rapid filtration technique. Cholecalciferol treatment (500 IU at 72 h) significantly enhanced selenite uptake, a response that decreased when the vesicles were stored at room temperature for 2.5 h prior to the uptake measurement. Preincubation of the vesicles in 1.0 mmol/L H2O2 reduced [75Se]selenite uptake, indicating the involvement of oxidizable groups in the uptake reaction. Iodoacetic acid (IAA), a sulfhydryl-blocking reagent, at 1-2 mmol/L concentration eliminated the difference in selenite uptake due to cholecalciferol and had no effect on vesicles from rachitic animals. A higher concentration of IAA (10 mmol/L) enhanced selenite uptake manyfold and increased the absolute difference due to cholecalciferol treatment. Single intravenous doses of 100 IU cholecalciferol, 100 IU ergocalciferol, or 0.1 micrograms 1,25-dihydroxycholecalciferol also stimulated selenite uptake, suggesting a general response to vitamin D compounds. Normal animals given a single dose of 1,25-dihydroxycholecalciferol 12 h prior to killing also responded. Treatments that enhanced the uptake of [75Se]selenite also increased the amount of membrane-bound sulfhydryl groups, suggesting the involvement of membrane-bound sulfhydryl groups in the vitamin D response. A significant increase in selenite uptake by intravenous 1,25-dihydroxycholecalciferol occurred within 10 min. This rapid effect provides a new tool to probe early biochemical effects of vitamin D on intestinal epithelium

    Full Text Available Plasmacytoid urothelial carcinoma (PUC of the urinary bladder is a rare and aggressive subtype of urothelial carcinoma. Its deceptive morphology is characterized by a discohesive growth of cells with plasmacytoid morphology. Since this tumor might be confused with plasmacytoma, lymphoma, or carcinoma variants, appropriate diagnosis in small biopsy samples could be challenging. This study reports the case of a 53-year-old man who presented with frequent nocturnal urgency, without hematuria. A transurethral bladder and a prostate resection specimen displayed infiltration of neoplastic cells in a spray-like discohesive pattern with occasional formation of small irregular nests and cord-like arrangements. The basic morphology of the tumor cells was plasmacytoid, with eccentric nuclei and eosinophilic cytoplasm. Tumor cells grew through the lamina muscularis mucosae, with splintering of the bladder wall musculature and infiltration of prostatic tissue. They displayed strong and diffuse nuclear reactivity for p53 and GATA3. Eight months after surgery, the patient experienced upper abdominal discomfort. A duodenal biopsy showed infiltration of plasmacytoid atypical cells strongly immunoreactive for GATA3, consistent with the previously diagnosed PUC. The patient died eleven months after the primary diagnosis of his PUC of tumor cachexia losing about 50% of his original body weight, furthermore, with ascites and intraperitoneal tumor spread.

Research is executed on 140 not purebred dogs which have been divided into six groups and united in two series. In the first series (30 dogs) were studied changes pancreatic exosecretion in the postoperative period of resection of duodenum (group 1.1), in the postoperative period of resection of duodenum with preliminary infiltration of a parapancreatic tissue of 0.5% by a solution of Novocain (group 1.2) and after resection of duodenum with application parapancreatic microirrigation (group 1.3). In the second series (110 dogs) were studied frequency of development of acute pancreatitis, enzymatic activity of blood serum and enzymatic activity of lymph of thoracal lymphatic duct after resection of duodenum (group 2.1) and in the postoperative period of resection of duodenum with preliminary infiltration of a parapancreatic tissue of 0.5% by a solution of Novocain (group 2.2) and after resection of duodenum with application parapancreatic microirrigation (group 2.3). Application parapancreatic microirrigation does not lead to oppression pancreatic exosecretion at the first o'clock after duodenotomy, and substantially reduces the pancreatic hypersecretion observed in the postoperative period of resection of a duodenum. In addition, application parapancreatic microirrigation reduces frequency of development of acute pancreatitis and promotes less expressed increase enzymatic activity of blood serum and enzymatic activity of lymph thoracal lymphatic duct at development of the given complication after operational trauma of duodenum in comparison with resection of duodenum and after a resection of a duodenum executed against infiltration of a parapancreatic tissue of 0.5% by a solution of Novocain.

    Peptic ulcer is an erosion of the mucosa gaster and duodenum. Aspirin can increase the activity of ROS in duodenum leading to be oxidative stress condition, followed by the increase expression of TNF-α and changes in the duodenum histopathology. Ethanolic extract from Sauropus androgynus (L.) Merr leaves contains flavonoid compound that act as antioxidants. The research aimed to study the therapeutic effect of Sauropus androgynus (L.) Merr leaves towards the expression of TNF-α and the duodenum histopathology. The study used five groups: the negative control group, the positive control group (peptic ulcer), and three therapeutic groups. Peptic ulcer induced by aspirin 200 mg/kg BW given orally once a day for five days. The therapeutic group (dose 16.2 mg/200 g BW, 32.4 mg/200 g BW, 48.6 mg/200 g BW) administrated orally once a day for fourteen days. Expression of TNF-α were analyzed by ANOVA followed by Tukey test (α=5%) and histopathology description of duodenum were analyzed descriptive qualitative. The result showed that treatment of the ethanolic extract from Sauropus androgynus (L.) Merr leaves at dose 48.6 mg/200 g BW was the effective dosage. The conclusion of this research indicate that ethanolic extract from Sauropus androgynus (L.) Merr leaves can be used as alternative therapy peptic ulcer towards decrease the expression of TNF-α and repair duodenum histopathology such as structure of epithelial duodenum, vile and decrease of inflammatory cell and vascular vasodilatation

    Full Text Available Abstract Background Its a dilemma to attempt a palliative procedure to debulk the tumour and/or prevent future obstructive complications in a locally advanced intra abdominal malignancy. Case presentation A 38 year old Vietnamese man presented with a carcinoma of the colon which had invaded the gallbladder and duodenum with a sealed perforation of the second part of the duodenum. Following surgical exploration, it was evident that primary closure of the perforated duodenum was not possible due to the presence of unresectable residual tumour. Conclusion We describe a novel technique using a covered duodenal stent deployed at open surgery to aid closure of a malignant duodenal perforation.

Early detection of the disease is dificult because doesn't have pathognomonic simptoms. The Whipple procedure is the optimal method of treatment. The authors relate one case of a adenocarcinoma of the duodenum in a 65- year-old white female with a history of abdominal pain for a six-month period, associated with postprandial fullness, vomiting and weight loss. Endoscopy showed a elevated tumor in the second part of the duodenum, with partial obstruction of the lumen. Histological study of endoscopic biopsies reveled a moderare differentiated adenocarcinoma of the duodenum. The treatment was surgical. The authors comment on the more important aspects of this pathology.

    2015-04-27

    Endoscopic retrograde cholangiography (ERCP) is currently standard treatment for biliary drainage. Endoscopic ultrasound guided rendezvous (EUS-RV) is a novel method to overcome an unsuccessful biliary drainage procedure. Under endoscopic ultrasound guidance a guidewire is passed via a needle from the stomach or duodenum to the common bile duct and from there on to the duodenum enabling ERCP. With a relatively high rate of success EUS-RV should be considered as an alternative to biliary drainage and surgical intervention.

    A symptom-causing duodenal stenosis diagnosed in a 47-year-old patient was found to be attributable to a malignant leiomyoblastoma. Ultrasonography, computerized tomography and MRI permitted a space-occupying process to be detected in the duodenum and a further tumour in the jejunum could be revealed by examinations of gastrointestinal transit. The presence of a total of three substantial tumours, one each in duodenum, jejunum and ileum, was however proven by angiography alone. (orig./MG)

    A 68-year-old Japanese woman underwent radiotherapy for gastric lymphoma. Although lymphangiectasia was sparsely observed in the second portion of the duodenum before radiotherapy, the number of pinpoint white spots obviously increased after the treatment. Although the duodenal lymphangiectasia gradually progressed, the patient had no features of protein-losing enteropathy. This case highlights the importance of endoscopic observation of the duodenum after irradiation to the abdomen as radiotherapy may secondarily cause intestinal lymphangiectasia. PMID:28798810

    Quantitative cholescintigraphy has been proposed as a noninvasive method to assess function of the sphincter of Oddi in cholecystectomized subjects. The present study evaluated several quantitative cholescintigraphic variables to assess their time-related variability as well as their capability to detect delay of choledochoduodenal bile flow. Cholescintigraphy with 2,6-diethylphenylcarbahoylmethyl diacetic acid 99mTc was performed in 24 cholecystectomized patients with recurrent biliary-like pain, laboratory evidence of bile stasis, normal hepatocellular function tests, and no evidence of choledocholithiasis. The study was also performed in 26 asymptomatic cholecystectomized subjects and repeated at 2-week intervals during identical experimental conditions in 10 of them. Of the following quantitative cholescintigraphic variables investigated, (a) hepatic T peak, (b) 50% hepatic retention (T peak, 1/2), (c) percent hepatic retention at 30 minutes, (d) percent hepatic retention at 40 minutes, (e) vein-hepatic hilum transit time, (f) vein-duodenum transit time, and (g) hepatic hilum-duodenum transit time, only the hepatic hilum-duodenum transit time showed a statistically significant correlation between the duplicate studies. Only vein-duodenum transit time and hepatic hilum-duodenum transit time discriminated the symptomatic from the asymptomatic patients; of the two variables, however, hepatic hilum-duodenum transit time showed less intrasubject variability and no overlap between the two groups of patients. Hepatic hilum-duodenum transit time showed a positive linear correlation with the maximum diameter of the choledochus. It is concluded that in cholecystectomized patients, the hepatic hilum-duodenum transit time appears to detect a delay of bile flow into the intestine better than any other cholescintigraphic variable

It showed an excentric opening of 0.8 cm diameter, but the dilated diaphragm caused a total stop during the last months. Despite a typical history, exact X-ray, and endoscopic examination, the correct preoperative diagnosis was not found, because nobody thought it possible, that a mucosal diapharm of the duodenum could persist for 34 years.

    The strains of Helicobacter pylori are described by many common features which determine their virulence. The genes which are connected with much higher virulence of some strains are vacA, cagA, oipA, dupA. Duodenal Ulcer Promoting Gene--dupA is the new virulence factor coexisting with a duodenum ulcer. There is a rationale that shows a protective character of dupA with reference to a stomach cancer. The dupA gene probably causes increasingly higher releasing of pro-infectious IL-8 via stomach cells and it influences the production of IL-12 and other cytokines. The aim of the study was to determine the frequency of dupA gene's appearance in the Polish children's group and in the Polish teenagers' group infected with H. pylori. The research was also aimed to determine the coexistence of dupA gene and duodenum ulcer disease or erosion infection of duodenum's mucous membrane. The endoscopic examination of the upper part of digestive duct was performed in 119 qualified patients with dyspeptic symptoms and with suspicion of stomach and duodenum's mucous membrane infection. The segments were taken for histopathological identification of H. pylori and for genetic indicating via PCR method. To confirm the presence of H. pylori in the extract the amplification of DNA fragment sized 860 pz was used. The presence of dupA gene was detected by PCR reaction with using the starters which include the fragment of jhp0917-jhp0918 sequence in the plastic H. pylori's genome area. To confirm the infection the urea breathing test was taken. 88 patients confirm the infection of H. pylori. The presence of dupA gene was found in 20 patients--a group A (22.7%), whereas in 68 patients dupA gene was not found--a group B (77.2%). Pathological changes in duodenum was found in 20 patients infected with H. pylori (22.7%), included 4 patients in the group A (20%) and 16 in the group B (23.5%). There was an infection (swelling, redness, congestion) in duodenum was found in the group A in all cases

  16. Stimulatory effect of Coca-Cola on gastroduodenal HCO3- secretion in rats.

    Sasaki, Y; Aihara, E; Ise, F; Kita, K; Takeuchi, K

    2007-10-01

    We examined the effect of various carbonated beverages, especially Coca-Cola, on the HCO3- secretion in the rat stomach and duodenum. Under urethane anaesthesia, a chambered stomach or a proximal duodenal loop was perfused with saline, and HCO3- secretion was measured at pH 7.0 using a pH-stat method and by adding 2 mM HCl. The amount of CO2 contained in these beverages was about 4-7 g/mL. Coca-Cola topically applied to the mucosa for 10 min significantly increased the HCO3- secretion in both the stomach and the duodenum. The HCO3- response in the duodenum was totally abolished by indomethacin and also partially inhibited by acetazolamide, an inhibitor of carbonic anhydrase. Likewise, the response in the stomach was also markedly inhibited by either acetazolamide or indomethacin. The mucosal application of Coca-Cola increased the PGE2 contents in both the stomach and the duodenum. Other carbonated beverages, such as sparkling water, Fanta Grape or cider, also increased the HCO3- secretion in these tissues. These results suggest that Coca-Cola induces HCO3- secretion in both the stomach and the duodenum, and these responses may be attributable to both the intracellular supply of HCO3- generated via carbonic anhydrase, and endogenous PGs, probably related to the acidic pH of the solution.

    The complications of the hydatid cyst of the liver are dominated by infection and rupture. The compression of adjacent organs (mainly the inferior vena cava, the portal vein and the bile ducts) can be seen, when the cyst is located in the dome, in the hilum or within the hepatic parenchyma. Upper digestive stenosis by compression of the duodenum by the hydatid cyst is an exceptional complication. A 63 year-old patient had, for two months, upper digestive stenosis associated with a sensation of weight in the right hypochondrium. Digestive endoscopy showed an extrinsic compression of the second portion of the duodenum. Biopsies were negative. Abdominal CT showed up a hydatid cyst in the segment VI of the liver, adhering to the duodenum, with an exo-vesiculation compressing it. The patient was operated on: There was a hydatid cyst of the right lateral sector compressing the duodenum. A partial intralamellar pericystectomy was performed. Hydatid cyst of the liver, a parasitic disease described as benign, may give mechanical complications related to compression of adjacent organs (especially the bile ducts and veins). Compression of the digestive tract is exceptional. This is due to the proximity of the cyst to the duodenum and the thickness of the cyst wall.

    2006-04-01

    Low-velocity gunshot wounds cause most civilian duodenal injuries. The objective of this study was to describe a simplified surgical algorithm currently in use in a South African civilian trauma center and to verify its validity by measuring morbidity and mortality. A retrospective chart review of patients with duodenal gunshot injuries during the study period January 1999 to December 2003 was performed. Data points accrued included patient demographics, admission hemodynamic status and resuscitative measures, laparotomy damage control procedures, methods of surgical repair of the duodenal injury, associated injuries, length of intensive care and hospital stays, complications, and mortality. A total of 75 consecutive patients with gunshot injuries to the duodenum were reviewed. Primary repair was performed in 54 patients (87%), resection and reanastomosis in 7 (11%), and pancreatoduodenectomy in 1 (2%) during the initial phases. The overall morbidity and mortality were 58% and 28%, respectively. Duodenum-related complications were recorded in nine (15%) patients: two duodenal fistulas, one duodenal obstruction, and six cases of suture-line dehiscence. Overall and duodenum-related morbidity rates in patients with combined pancreatoduodenal injuries were 83% and 17%, respectively. Duodenum-related mortality occurred in three (4.8%) patients. Most civilian low-velocity duodenal gunshot injuries treated with simple primary repair result in overall morbidity, mortality, and duodenum-related complication rates comparable to those in reports where more complex surgical procedures were employed. Primary repair is also applicable for most combined pancreatic and duodenal gunshot injuries.

    Lee, A.W.; Ram, M.D.; Shih, W.J.; Murphy, K.

    1986-01-01

    Biliary scintigraphy using 99mTc p-butyl acetanilidiminodiacetic acid (BIDA) was performed as part of the diagnostic evaluation on 96 patients with jaundice (serum bilirubin greater than 2 mg/dl) to assess its value in this group of patients. The results of scintigraphy revealed no obstruction to the flow of the scintigraphic agent into the duodenum in 54 patients, delayed appearance of the agent (normal upper limit 60 min) in the duodenum indicating partial obstruction in 22 patients, and complete obstruction of the duct demonstrated by absence of agent in the duodenum in 20 patients. The findings were correlated with the final diagnosis and the overall results show accuracy of 92.7%, sensitivity of 97.3%, and specificity of 89.8%. Biliary scintigraphy was thus found to be useful in differentiating nonobstructive, partially obstructive, and completely obstructive causes of jaundice

  20. Congenital Membrane Causing Duodenal Obstruction and Malpositioning of the Descending Colon

    Directory of Open Access Journals (Sweden)

    Chee-Chee Koh

    2013-08-01

    Full Text Available A congenital membrane without intestinal malrotation is a rare cause of duodenal obstruction. Here we present an 11-year-old girl who had suffered from intermittent abdominal cramping pain and vomiting for more than 5 years. The image studies, including a plain abdomen roentgenogram and sonogram, showed no definite diagnosis. The upper gastrointestinal series and small bowel series showed the contrast was static over the third portion of the duodenum and the descending colon pulled up toward the epigastric area. Laparoscopic exploration revealed a congenital membrane extending from the right-side paraduodenal peritoneum through the third portion of the duodenum to the descending colon, which had caused obstruction of the third portion of the duodenum and malpositioning of the descending colon. To the best of our knowledge, this is the first case report in the literature where a congenital membrane caused both duodenal obstruction and malpositioning of the descending colon.

  1. Stereomicroscopic and ultrastructural characterization of propionitrile-induced duodenal ulcer in the rat

    Poulsen, Steen Seier

    1978-01-01

    Acute duodenal ulcer produced by subcutaneous injection of propionitrile in rats was studied by stereo, light, and electron microscopy in order to gain insight into the localization and mechanism of initial cell injury. Stereomicroscopy revealed an initial fissuring and splitting of the tips...... of the villus folds within 4 hours after two injections of propionitrile. This was followed by sloughing of the epithelium, shortening and effacement of the villus folds, and within 24 hours the appearance of discrete ulcers in the mucosa of the proximal duodenum. In most of the rats, two ulcers developed......: the first and larger ulcer was on the antimesenteric side of the duodenum, and the other, a small and more superficial one, was on the opposite wall. Ultrastructural lesions appeared in the absorptive epithelial cells of the proximal duodenum within 5 hours following a single dose of propionitrile...

    An experiment to study the absorption of calcium through the duodenum of vitamin D deficient chickens was conducted using radiocalcium as tracer. In this experiment twenty chickens were reared from one day old chicken until one month and maintained on rachitogenic diet. Vitamin D was given to ten chickens orally fourty eight hours prior to the administration of radiocalcium. The result of this experiment indicated that the absorption of calcium in the duodenum was higher in chickens provided with vitamin D compared to those without vitamin D (P≤0.01). (author)

    2011-09-01

    Intestinal lymphangiectasia may occur as a primary congenital disorder or a secondary disorder. Secondary lymphangiectasia could be associated with diseases such as abdominal carcinoma, retroperitoneal fibrosis or chronic pancreatitis. This is the first reported case of intestinal lymphangiectasia associated with recurrent histiocytosis X. This case report illustrates the need for more prospective, well-designed studies to determine the natural history and outcome of intestinal lymphangiectasia in the duodenum. Hopefully, these studies will also help clinicians identify which group of patients with intestinal lymphangiectasia in the duodenum is more likely to have a secondary cause.

    Efficiency of the reinfusion method for autoblood irradiated by UV-rays during the treatment of 40 patients with peptic ulcer of duodenum and 8 patients with peptic ulcer of stomach is studied. It isestablished that the method above promotes the fast improvement of state of health in patients, the normalization of sleep, appetite, the disappearance of asthenias, aches and the reduction of time of ulcer cicatrization up to 14±4 days. It is supposed that high efficiency of the method is caused by the improvement of microcirculation and trophicity of mucous membrane of stomach and duodenum

    In 4 pigs (live weight 63 kg) with re-entrance cannulae in the duodenum as well as in the ileocecal region intake, excretion and flow rate of protein, methionine and 35 S were measured after supplementary oral application of 35 S-methionine to a wheat-wheat gluten-lysine diet and a protein-free diet, respectively, over a period of 7 days. For both the N and the methionine metabolism patterns were outlined according to the measured values and with the aid of a compartment model. The endogenous and exogenous levels of proteins and methionine in the duodenum, ileum and feces were estimated

  7. The immune cell composition in Barrett's metaplastic tissue resembles that in normal duodenal tissue.

    Directory of Open Access Journals (Sweden)

    Alexandra Lind

    Full Text Available BACKGROUND AND OBJECTIVE: Barrett's esophagus (BE is characterized by the transition of squamous epithelium into columnar epithelium with intestinal metaplasia. The increased number and types of immune cells in BE have been indicated to be due to a Th2-type inflammatory process. We tested the alternative hypothesis that the abundance of T-cells in BE is caused by a homing mechanism that is found in the duodenum. PATIENTS AND METHODS: Biopsies from BE and duodenal tissue from 30 BE patients and duodenal tissue from 18 controls were characterized by immmunohistochemistry for the presence of T-cells and eosinophils(eos. Ex vivo expanded T-cells were further phenotyped by multicolor analysis using flowcytometry. RESULTS: The high percentage of CD4(+-T cells (69±3% (mean±SEM/n = 17, by flowcytometry, measured by flowcytometry and immunohistochemistry, and the presence of non-activated eosinophils found in BE by immunohistochemical staining, were not different from that found in duodenal tissue. Expanded lymphocytes from these tissues had a similar phenotype, characterized by a comparable but low percentage of αE(CD103 positive CD4(+cells (44±5% in BE, 43±4% in duodenum of BE and 34±7% in duodenum of controls and a similar percentage of granzyme-B(+CD8(+ cells(44±5% in BE, 33±6% in duodenum of BE and 36±7% in duodenum of controls. In addition, a similar percentage of α4β7(+ T-lymphocytes (63±5% in BE, 58±5% in duodenum of BE and 62±8% in duodenum of controls was found. Finally, mRNA expression of the ligand for α4β7, MAdCAM-1, was also similar in BE and duodenal tissue. No evidence for a Th2-response was found as almost no IL-4(+-T-cells were seen. CONCLUSION: The immune cell composition (lymphocytes and eosinophils and expression of intestinal adhesion molecule MAdCAM-1 is similar in BE and duodenum. This supports the hypothesis that homing of lymphocytes to BE tissue is mainly caused by intestinal homing signals rather than to an

  8. Rare Case of Duodenal Metastasis From Pulmonary Squamous Cell Carcinoma

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available Pulmonary squamous cell carcinoma is the second most common non–small cell malignancy of the lung. It commonly metastasizes to the adrenal glands, bone, liver, brain, and kidneys. Most occurrences of metastatic squamous cell carcinoma involving the gastrointestinal tract originate from primary lung tumors. Metastasis to the duodenum, however, is exceedingly rare, with very few cases of stomach or duodenal involvement described in the literature. We report the case of a patient with stage IV pulmonary squamous cell carcinoma metastasizing to the duodenum with an uncommon presentation to add to the paucity of literature available regarding this rare finding.

    This chapter explains the procedure of ethanol-induced ulcer to check the protective effect of drugs over induced ulcer in rats. Ulcer is defined as the erosion in the lining of the stomach or duodenum and is caused by the disruptions of the gastric mucosal defence and repair systems. Ulceration of stomach is called gastric ulcer and that of duodenum is called duodenal ulcer and together peptic ulcer. In clinical practice, peptic ulcer is one of the most prevalent gastrointestinal disorders, which commonly occurs in developed countries.

    2018-01-01

    Primary intestinal lymphangiectasia (PIL) is a rare, presumably congenital lesion that is usually diagnosed in patients lymphangiectasia. EGD with intubation to mid-descending duodenum revealed no significant lesions, but subsequent enteroscopy demonstrated lesions in distal duodenum/proximal jejunum similar to those in terminal ileum characteristic of lymphangiectasia. Histopathologic analysis of lesions of terminal ileum/distal duodenum demonstrated dilated mucosal vessels, confirmed as lymphatic vessels by immunohistochemistry. PIL was diagnosed after excluding secondary causes of intestinal lymphangiectasia. Patient placed on standard PIL diet: oral supplements of medium-chain triglycerides, a high protein diet, supplements of fat-soluble vitamins, and avoiding long-chain fatty acids, with marked clinical improvement. This work shows that: 1)-standard EGD and colonoscopy may miss characteristic lesions of PIL, 2)-enteroscopy or terminal ileal intubation at colonoscopy may be required for the diagnosis because lesions are typically located in distal duodenum/jejunoileum; and 3)-PIL can first present in the very elderly even with symptoms of short duration.

    Imaging of common bile duct(CBD) can be done by many techniques. Endoscopic retrograde cholangiopancreaticography is considered the gold standard for imaging of CBD. A standard technique of imaging of CBD by endoscopic ultrasound(EUS) has not been specifically described. The available descriptions mention different stations of imaging from the stomach and duodenum. The CBD lies closest to duodenum and choice of imaging may be restricted to duodenum for many operators. Generally most operators prefer multi station imaging during EUS and the choice of selecting the initial station varies from operator to operator. Detailed evaluation of CBD is frequently the main focus of imaging during EUS and in such situations multi station imaging with a high-resolution ultrasound scanner may provide useful information. Examination of the CBD is one of the primary indications for doing an EUS and it can be done from five stations:(1) the fundus of stomach;(2) body of stomach;(3) duodenal bulb;(4) descending duodenum; and(5) antrum. Following down the upper 1/3rd of CBD can do imaging of entire CBD from the liver window and following up the lower 1/3rd of CBD can do imaging of entire CBD from the pancreatic window. This article aims at simplifying the techniques of imaging of CBD by linear EUS.

    Stereotactic body radiotherapy (SBRT) shows promise in unresectable pancreatic cancer, though this treatment modality has high rates of normal tissue toxicity. This study explores the dosimetric utility of daily adaptive re-planning with pancreas SBRT. We used a previously developed supercomputing online re-planning environment (SCORE) to re-plan 10 patients with pancreas SBRT. Tumor and normal tissue contours were deformed from treatment planning computed tomographies (CTs) and transferred to daily cone-beam CT (CBCT) scans before re-optimizing each daily treatment plan. We compared the intended radiation dose, the actual radiation dose, and the optimized radiation dose for the pancreas tumor planning target volume (PTV) and the duodenum. Treatment re-optimization improved coverage of the PTV and reduced dose to the duodenum. Within the PTV, the actual hot spot (volume receiving 110% of the prescription dose) decreased from 4.5% to 0.5% after daily adaptive re-planning. Within the duodenum, the volume receiving the prescription dose decreased from 0.9% to 0.3% after re-planning. It is noteworthy that variation in the amount of air within a patient's stomach substantially changed dose to the PTV. Adaptive re-planning with pancreas SBRT has the ability to improve dose to the tumor and decrease dose to the nearby duodenum, thereby reducing the risk of toxicity.

    This study investigated effects of xanthophylls (containing 40% lutein and 60% zeaxanthin) on gene expression of inflammatory mediators ( [] and []) and apoptosis ( [] and ) of breeding hens and chicks. In Exp. 1, 432 hens were divided into 3 groups and fed diets supplemented with 0 (as the control group), 20, or 40 mg/kg xanthophylls. The liver, duodenum, jejunum, and ileum were sampled after 35 d. Results showed that 40 mg/kg of xanthophyll addition decreased in the liver, in the liver and duodenum, and in the liver and jejunum while increasing level in the liver and jejunum. Experiment 2 was a 2 × 2 factorial design. Male chicks hatched from hens fed 0 or 40 mg/kg xanthophyll diets were fed diets containing either 0 or 40 mg/kg xanthophylls. The liver, duodenum, jejunum, and ileum were sampled at 0, 7, 14, and 21 d after hatching. Results showed that in ovo xanthophylls reduced inflammatory mediators and apoptosis in the liver, duodenum, and jejunum of chicks mainly within 1 wk after hatching, whereas dietary xanthophylls only decreased expression in the liver from 2 wk onward. These results underlined important anti-inflammatory and antiapoptotic effects of maternal but not progeny dietary xanthophylls. In conclusion, xanthophylls can suppress inflammatory mediators and apoptosis in different tissues of hens and chicks.

    Diverticulum is considered as a common lesion involving any gastrointestinal tract from the pharynx to the rectum. We reviewed 5,806 cases of upper G-I series and 801 cases of double contrast barium enema during the period from Jan.1978 to Dec. 1981 in the Department of Radiology, School of Medicine, Jeonbug National University Hospital to analyze diverticula of the entire gastrointestinal tract. The results were as follows: 1. Roentgen examination of 5,806 esophagus, stomachs, duodenums and small bowels, and 801 colons during the past four years: diverticula of the esophagus, 60 cases (1.0%); diverticula of the stomach, 42 cases (0.7%); diverticula of the duodenum, 358 cases (6.2%); diverticula of the small bowel, 20 cases (0.3%); diverticula of the colon, 26 cases (3.2%). The location of diverticula in order of frequency was duodenum, colon, esophagus, stomach and small bowel. 2. The most common site of diverticula of each gastrointestinal tract was as follows: diverticula of the esophagus, middle portion (84.7%); diverticula of the stomach, the cardia (59.5%); diverticula of the duodenum, the second portion (81.3%); diverticula of the small bowel, the jejunum (96.4%)-especially the larger percentage were observed at the upper jejunum near the ligament of Treitz; diverticula of the colon, the right sided colon (80.8%)-the cecum and ascending colon (57.1%). 3. Diverticula may occur at any age. The majority of diverticula of the entire gastrointestinal tract were observed over 40 years of age. Especially in diverticula of the duodenum and colon, their frequency increase with age. 4. Duodenal diverticula were observed more frequently in woman than in man but in diverticula of the esophagus, stomach, small bowel and colon, male was more frequently affected. 5. The size of diverticula of the entire gastrointestinal tract was variable. The majority of diverticula of the esophagus, stomach, duodenum and small bowel were intermediate in size (10-49 mm).

    To consolidate duodenum and small bowel toxicity data from clinical studies with different dose fractionation schedules using the modified linear quadratic (MLQ) model. A methodology of adjusting the dose-volume (D,v) parameters to different levels of normal tissue complication probability (NTCP) was presented. A set of NTCP model parameters for duodenum toxicity were estimated by the χ(2) fitting method using literature-based tolerance dose and generalized equivalent uniform dose (gEUD) data. These model parameters were then used to convert (D,v) data into the isoeffective dose in 2 Gy per fraction, (D(MLQED2),v) and convert these parameters to an isoeffective dose at another NTCP (D(MLQED2'),v). The literature search yielded 5 reports useful in making estimates of duodenum and small bowel toxicity. The NTCP model parameters were found to be TD50(1)(model) = 60.9 ± 7.9 Gy, m = 0.21 ± 0.05, and δ = 0.09 ± 0.03 Gy(-1). Isoeffective dose calculations and toxicity rates associated with hypofractionated radiation therapy reports were found to be consistent with clinical data having different fractionation schedules. Values of (D(MLQED2'),v) between different NTCP levels remain consistent over a range of 5%-20%. MLQ-based isoeffective calculations of dose-response data corresponding to grade ≥2 duodenum toxicity were found to be consistent with one another within the calculation uncertainty. The (D(MLQED2),v) data could be used to determine duodenum and small bowel dose-volume constraints for new dose escalation strategies. Copyright © 2014 American Society for Radiation Oncology.

    The annular pancreas is a congenital anomaly in which pancreatic tissue partially or completely surrounds the second portion of the duodenum. Its often located above of papilla of Vater (85%), rarely below (15%). This pancreatic tissue is often easily dissociable to the duodenum but there is same cases where it the tissue is into the muscolaris wall of the duodenum. We describe three case of annular pancreas hospitalized in our facility between January 2004 and January 2009. There were 2 male 65 and 69 years old respectively and 1 female of 60 years old, presented complaining of repeated episodes of mild epigastric pain. Laboratory tests (including tumor markers), a direct abdomen X-ray with enema, EGDS and total body CT scan were performed to study to better define the diagnosis. EUS showed the presence of tissue infiltrating the muscle layer all around the first part of duodenum. Biopsies performed found the presence of pancreatic tissue with focal areas of adenocarcinoma. Subtotal gastrectomy with Roux was performed. The histological examinations shows an annular pancreas of D1 with multiple focal area of adenocarcinoma. (T1aN0M0). We performed a follow up at 5 years. One patients died after 36 months for cardiovascular hit. Two patients, one male and one female, was 5-years disease-free. Annular pancreas is an uncommon congenital anomaly which usually presents itself in infants and newborn. Rarely it can present in late adult life with wide range of clinical severities thereby making its diagnosis difficult. Pre-operative diagnosis is often difficult. CT scan can illustrate the pancreatic tissue encircling the duodenum. ERCP and MRCP are useful in outlining the annular pancreatic duct. Surgery still remains necessary to confirm diagnosis and bypassing the obstructed segment. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

    It was known that some of the abdominal tuberculosis can produce tumor-like appearance clinically and radiologically. But these were mainly masses formed in mesenteric and retroperitoneal lymph nodes. The author has experienced the gastrointestinal tuberculosis resembling to a neoplastic process. In the gastric tuberculosis, irregular narrowing and filling defect with mucosal distortion and occasional shoulder effect could be seen in pyloric antrum. Deformity of proximal portion of duodenum was noted in most cases. Difficulty in differential diagnosis from the gastric cancer might be encountered. If duodenum was not involved. No definite sign of mucosal destruction involved area and associated deformity of duodenum was suggestive of an inflammatory lesion. If there is any tuberculous changes in small bowel, than gastric tuberculosis is more likely. There was the tuberculosis of descending duodenum or pancreaticoduodenal group of lymph nodes revealed cancer-like appearance. Long irregular narrowing with nodular filling defect and mucosal distortion or inverted 3 sign was evident. Differential diagnosis from cancer in duodenum or pancreas could not be made radiographically. Short annular stenosis and nodular filling defect with shoulder effect in both ends of stenosis was noted in some of small bowel tuberculosis. The findings were very resemble to malignancy. There was a case of huge hepatoma-like tuberculosis formed a large irregular mass by lymph nodes and adjacent organs. Chest film was not much help in the differential diagnosis. In many cases of the gastrointestinal tuberculosis, radiological findings were resembled to a neoplastic process. Since none of radiologic findings are specific enough to allow one to make a definitive diagnosis of the gastrointestinal tuberculosis and since type of the gastrointestinal tuberculosis could be cured by chemotherapy, careful analyzation of clinical features is emphasized before surgery.

    This study was designed to investigate effects of xanthophylls on serum lipid profile (triglyceride, TG; cholesterol, CHO; high-density lipoprotein cholesterol, HDLC; and low-density lipoprotein cholesterol, LDLC) and nuclear factor (peroxisome proliferator-activated receptor gamma, PPARγ; PPAR gamma coactivator 1 alpha, PGC1α; retinoid X receptor gamma, RXRγ; and retinoic acid receptor alpha, RARα) gene expression of breeding hens and chicks. In experiment 1, 432 hens were divided into three groups and fed diets supplemented with 0 (as control group), 20 or 40 mg/kg xanthophylls. Blood was sampled at 7, 14, 21, 28 and 35 days of trial. Liver, duodenum, jejunum and ileum were sampled at 35 days of trial. Results showed that serum HDLC level of hens was increased after dietary 40 mg/kg xanthophyll addition for 21, 28 and 35 days, while serum TG, CHO and LDLC were not affected. Xanthophyll addition also increased PPARγ expression in jejunum, RXRγ expression in duodenum and jejunum, and RARα expression in liver and duodenum. Experiment 2 was a 2 × 2 factorial design. Male chicks hatched from 0 or 40 mg/kg xanthophyll diet of hens were fed diet containing either 0 or 40 mg/kg xanthophylls. Liver, duodenum, jejunum and ileum were sampled at 0, 7, 14 and 21 days after hatching. Blood samples were also collected at 21 days. Results showed that in ovo xanthophylls elevated PPARγ in duodenum and jejunum, and RXRγ and RARα in liver of chicks mainly within 1 week after hatching, while dietary xanthophylls increased serum HDLC level and PPARγ and RXRγ in liver from 2 weeks onwards. In conclusion, our research suggested xanthophylls can regulate serum lipid profile and nuclear factor expression in hens and chicks. © 2017 Blackwell Verlag GmbH.

    Gastroduodenal intussusception is a rare condition caused by the prolapse of a gastric tumor with subsequent invagination of a portion of the gastric wall into the duodenum. Various gastric lesions including adenoma, lipoma, leiomyoma, hamartoma, adenocarcinoma, gastrointestinal stromal tumor (GIST), and as in our case a Peutz- Jeghers polyp, can serve as a lead point of intussusception. Only three cases of gastroduodenal intussusception secondary to a Peutz-Jeghers polyp have been reported. We experienced a case of gastroduodenal intussusception in a 36-month-old boy who presented with intermittent nonbilious vomiting, abdominal pain, and anemia. An abdominal ultrasound and contrast enhanced CT scan showed gastrointestinal intussusception and a mass-like lesion in the second portion of duodenum. A laparotomy revealed a 7x8 cm sized mass at the gastric body, which was pathologically confirmed as a Peutz-Jeghers polyp

    We report the successful conversion of percutaneous cholecystostomy (PC) to endoscopic transpapillary gallbladder stenting (ETGS) with insertion of an antegrade guidewire into the duodenum. An 84-year-old man presented with severe acute cholecystitis and septic shock. He had significant comorbidities, and emergent PC was successfully performed. Subsequent ETGS was attempted but unsuccessful owing to difficulties with cystic duct cannulation. However, via the PC tract, the guidewire was passed antegradely into the duodenum, and ETGS with a double-pigtail plastic stent was successfully performed with the rendezvous technique. The PC tube was removed, and no recurrence was reported during the 17-month follow-up period. Conversion of PC to ETGS is a viable option in patients with acute cholecystitis who are not candidates for surgery. Antegrade guidewire insertion via the PC tract may increase the success rate of conversion and decrease the risk of procedure-related complications.

    Effect of γ-irradiation with lethal dose (1000 rads) on alkaline phosphatase and glucose-6-phosphatase have been studied in two different regions (duodenum and ileum) of small intestine of pigeons. The enzymes were studied at different intervals like 2, 4, 6 and 8 days after irradiation. The sp. activities of enzyme increased significantly both in duodenum and ileum. However, significant increase in alkaline phosphatase and glucose-6-phosphatase were observed at the 2nd and the 4th days post-irradiation respectively. The increase in enzyme activities may present de novo synthesis of these enzymes after lethal dose of irradiation. The histologic picture revealed that after the 4th day of irradiation, the number of goblet cells increased and after the 6th day crypt-villus system was destroyed completely as compared to sham-irradiated pigeons.

The enzymes were studied at different intervals like 2, 4, 6 and 8 days after irradiation. The sp. activities of enzyme increased significantly both in duodenum and ileum. However, significant increase in alkaline phosphatase and glucose-6-phosphatase were observed at the 2nd and the 4th days post-irradiation respectively. The increase in enzyme activities may present de novo synthesis of these enzymes after lethal dose of irradiation. The histologic picture revealed that after the 4th day of irradiation, the number of goblet cells increased and after the 6th day crypt-villus system was destroyed completely as compared to sham-irradiated pigeons.

    Full Text Available We report the successful conversion of percutaneous cholecystostomy (PC to endoscopic transpapillary gallbladder stenting (ETGS with insertion of an antegrade guidewire into the duodenum. An 84-year-old man presented with severe acute cholecystitis and septic shock. He had significant comorbidities, and emergent PC was successfully performed. Subsequent ETGS was attempted but unsuccessful owing to difficulties with cystic duct cannulation. However, via the PC tract, the guidewire was passed antegradely into the duodenum, and ETGS with a double-pigtail plastic stent was successfully performed with the rendezvous technique. The PC tube was removed, and no recurrence was reported during the 17-month follow-up period. Conversion of PC to ETGS is a viable option in patients with acute cholecystitis who are not candidates for surgery. Antegrade guidewire insertion via the PC tract may increase the success rate of conversion and decrease the risk of procedure-related complications.

    Full Text Available Brunner’s gland hamartoma, also called hyperplasia, adenoma, and Brunneroma, is an extremely rare benign proliferative lesion of Brunner’s glands in the duodenum. While being mostly small and asymptomatic, they can result in gastrointestinal bleeding and obstruction. We report the case of a 54-year-old man presenting with melena and severe anemia requiring blood transfusion. CT scans showed a large mass of 8 cm in diameter, presumably arising in the duodenum. Endoscopic biopsies were not conclusive. As we were unable to determine the nature of the mass preoperatively and due to the severe symptoms, its size, and the uncertain malignant potential, a classic Whipple procedure was performed. The resected specimen showed extensive proliferation of Brunner’s glands without signs of malignancy.

    Metastatic disease to the stomach or duodenum is an infrequent diagnosis, and head and neck squamous cell carcinoma (HNSCC) is one of the least common primary malignancies that lead to gastric or duodenal metastases. We report the case of a 65-year-old man with human immunodeficiency virus infection and previously diagnosed HNSCC who presented with melena. The patient had a percutaneous endoscopic gastrostomy tube placed 3 months prior to his presentation. Laboratory testing was significant for normocytic anemia and a digital rectal examination was positive for melena. Esophagogastroduodenoscopy revealed numerous cratered nodules with contact bleeding in the stomach as well as the duodenum that appeared malignant. Biopsies of the gastric and duodenal nodules were positive for p40 and CK 5/6, consistent with metastatic squamous cell carcinoma.

    Full Text Available Peptic mucus synthesize especially prostaglandine E2 and I2. Prostaglandine E2 and I2 can impede acid secrete and stimulate mucus and bicarbonate secretion. Misoprostof, a synthetic methyl ester analogue of prostaglandin is both a powerful inhibitor of gastric secretion and is able to protect the gastroduodenal mucosa from damage. Misoprostol and other prostaglandine derivatives can be alternative drug of peptic ulcer relapse because the metyl ester of prostaglandin exert an antisecretion and protective effects on peptic mucus. The clinical effectiveness of misoprostol is comparable to cimethidin in short term treatment of peptic and duodenum ulcer as well as reducing duodenal ulcer relapse. Misoprostol may prevent gastrointestinal and peptic ulcer in long term treatment of Non Steroid Anti Jnflamation Drug. The side effect of misoprostol is cervix maturation and uterotonic. This article describe misoprostol effictiveness on peptic and duodenum ulcer treatment.   Key Words: Misoprostol, Peptik ulcer, Sitoproteksi

    The anlage of duodenum, ileum and colon were removed from chick embryos of day 8-21 of incubation and from 1-day-old chicks. A battery of seven different horseradish peroxidase-conjugated lectins (PNA, SBA, DBA, Con A, WGA, LTA and UEAI) was used to study the carbohydrate residues of the glycoconjugates in the goblet cells of the three parts of the intestine. The main results can be summarized as follows: differences in lectin binding were absent in the proximal and distal parts of the duodenum, ileum and colon. Lectin histochemistry showed differences among the three intestinal segments for the time of appearance of the oligosaccharides in the goblet mucus. In the colonic goblet cells of 1-day-old chicks, LTA and UEAI lectins showed two different types of linkage of alpha-L-fucose. This is the first demonstration of UEAI reactive sites in Gallus domesticus.

    The experiment aimed to specifically monitor the passage of lactobacilli in vivo after oral administration. The green fluorescent protein (GFP) gene was cloned downstream from the constitutive p32 promoter from L. lactis subsp. cremoris Wg2. The recombinant expression vector, pLEM415-gfp-p32, was electroporated into Lactobacillus plantarum (L. plantarum) isolated from goat. Green fluorescent protein (GFP) was successfully expressed in L. plantarum. After 2 h post-administration, transformed Lactobacillus could be detectable in all luminal contents. In the rumen, bacteria concentration initially decreased, reached the minimum at 42 h post-oral administration and then increased. However, this concentration decreased constantly in the duodenum. This result indicated that L. plantarum could colonize in the rumen but not in the duodenum.

    Full Text Available The aim of this work was to study the effect of Halymenia floresia (Hf on duodenum contractility, and on experimental protocols of gastric compliance (GC in rats. Fraction Hf2s exhibited a concentration-dependent myocontractile effect (EC50 12.48 µg/ml, and an inhibitory effect after consecutive washing. The contractile response promoted by Hf2s in the duodenum strips was completely inhibited by verapamil, and the effects were prevented in the presence of Ca2+-free medium. The pretreatment with atropine prevented the Hf2s myocontractile effect. Hf2s was also capable to decrease the GC (from 3.8±0.06 to 3.4±0.13 ml, P<0.05, which did not return to basal levels after more 50 min of observation. These results indicated that the algal polysaccharide possessed in vitro and in vivo gastrointestinal effects.

    We report the case of a 12-year-old boy who presented after a bicycle accident with handlebar injury of the epigastrium with clinical signs of hollow visceral injury and elevated pancreatic enzymes. Upon emergency laparotomy, a complete rupture of the pancreatic isthmus and a nearly total transsection of the postpyloric duodenum were encountered (Grade IV according to Lucas). Reconstruction consisted of reanastomosis of the proximal duodenum, closure of the distal end of the pancreatic head and internal drainage of the left pancreas into a Roux-en-Y jejunal loop. The postoperative course was uneventful. For rare traumatic pancreaticoduodenal lesions only individual surgical concepts are promising depending on the extent of damage. However, effort should be made to preserve as much pancreatic tissue as possible.

    Abdominal ultrasonography was performed in six adult captive caracals (Caracal caracal) to describe the normal abdominal ultrasonographic anatomy. Consistently, the splenic parenchyma was hyperechoic to the liver and kidneys. The relative echogenicity of the right kidney's cortex was inconsistent to the liver. The gall bladder was prominent in five animals and surrounded by a clearly visualized thin, smooth, regular echogenic wall. The wall thickness of the duodenum measured significantly greater compared with that of the jejunum and colon. The duodenum had a significantly thicker mucosal layer compared with that of the stomach. Such knowledge of the normal abdominal ultrasonographic anatomy of individual species is important for accurate diagnosis and interpretation of routine health examinations.

    Full Text Available Although duodenal perforation is currently an infrequent complication of medical procedures, its incidence in the future predictably will increase as endoscopic treatment of duodenal neoplasms becomes more frequently used. In some cases, duodenal perforation is difficult to treat even surgically. We report here a novel technique called ‘triple-tube-ostomy’ for the treatment of iatrogenic duodenal perforation. Since November 2009, there have been three cases of iatrogenic perforation of the duodenum, due to various causes, which we have treated with our novel technique. The main principles of the technique are biliary diversion, decompression of the duodenum, and early enteral nutrition. All patients who underwent the triple-tube-ostomy procedure had good postoperative courses, with few complications. The novel surgical technique we describe in this report is safe, reliable, easy to learn and perform, and led to a good postoperative course in all cases where we performed it.

    1981-02-01

    A 56-year-old man with hepatoma, who had been treated with total 3,960 rad of /sup 60/Co-irradiation 2 months previously, was readmitted to the hospital because of fever and anemia. Following admission, he passed tarry stools every day. Barium meal examination revealed esophageal varices and erosive gastritis of the antrum. At endoscopy, many hemorrhagic erosions were found in the gastric antrum and the first part of duodenum, which were located in the irradiation area. Since repeated blood transfusion failed to improve anemia, a complete fasting with intravenous hyperalimentation and antacid therapy were started. Two months later, feeding was started and thereafter continued without any appreciable GI bleeding or worsening of anemia. Endoscopic examination at this time revealed only a few erosions scattered over the edematous antral mucosa as well as the proximal duodenum. IVH, antacids and abstinence from food seem to be an effective measure in the treatment of radiation injury of the gut.

    Full Text Available Abstract Introduction Superior mesenteric artery syndrome is a rare cause of upper intestinal obstruction resulting from compression of the duodenum by the superior mesenteric artery and abdominal aorta. Case presentation We describe a case of superior mesenteric artery syndrome in a 61-year-old Japanese man with non-small cell lung cancer who had been treated with cisplatin-containing chemotherapy and had lost 7 kg in weight. The diagnosis was confirmed by the typical findings of abdominal computed tomography showing distended stomach resulting from compression of the third portion of the duodenum and reduction of an aortomesenteric distance and aortomesenteric angle. Conclusions This case highlights the importance of considering the possibility of superior mesenteric artery syndrome in patients treated with chemotherapy, especially those presenting with a low body mass index and showing weight loss during chemotherapy.

In all patients submitted to the ratio-isotopic estimation of the duodeno-gastric reflux as well as to the chromatographic determination of the concentration of bile acids and lysolecithin in the gastric juice, an almost identically frequent occurrence of the reflux of the duodeno gastric contents into the ulcer of the stomach and of the duodenum was confirmed. It was shown that half of the ulcers of the stomach originate without the participation of the duodeno gastric reflux. It was also established that the average total concentrations of bile acids and lysolecithin are very high in the gastric juice, and in some even statistically significant cases, in the ulcer of the stomach in comparison with the remaining analysed groups of patients.

    Full Text Available When dealing with gastric cancer with duodenal invasion, gastrectomy with distal resection of the duodenum is necessary to achieve negative distal margin. However, rupture of an ultralow duodenal stump necessitates advanced surgical skills and close postoperative observation. The present study reports a case of an early duodenal stump rupture after subtotal gastrectomy with resection of the whole first part of the duodenum, complete omentectomy, bursectomy, and D2+ lymphadenectomy performed for a pT3pN2pM1 (+ number 13 lymph nodes adenocarcinoma of the antrum. Duodenal stump rupture was managed successfully by end tube duodenostomy, without omental patching, and tube cholangiostomy. Close assessment of clinical, physical, and radiological signs, output volume, and enzyme concentration of the tube duodenostomy, T-tube, and closed suction drain, which was placed near the tube duodenostomy site to drain the leak around the catheter, dictated postoperative management of the external duodenal fistula.

    2016-12-01

    Duodenal phytobezoar, an unusual cause of acute duodenal obstruction, is rarely seen. The most common cause of this type of bezoar is persimmon. It frequently arises from underlying gastrointestinal tract pathologies (gastric surgery, etc.). Here, we report the case of a 66-year-old man who had undergone distal gastrectomy with Billroth I reconstruction for gastric cancer and experienced severe epigastric discomfort, abdominal pain, and vomiting for a few days. The abdominal computed tomography scan showed a large-sized mass in the horizontal portion of the duodenum. On following endoscopic examination, a large phytobezoar was revealed in the duodenum. He was treated with endoscopic fragmentation combined with nasogastric Coca-Cola. The patient tolerated the procedure well and resumed a normal oral diet 3 days later.

    Primary intestinal lymphangiectasia (Waldmann's disease) lead to a protein-losing enteropathy due to lymph leak into intestinal tract. A 28-year-old woman presented a bilateral lower limb lymphedema. Laboratory examination showing lymphopenia, hypoalbuminemia, hypogammaglobulinemia suggested the diagnosis of primary intestinal lymphangiectasia. Gastroscopy was normal and second duodenum biopsies were negative. Videocapsule endoscopy gave evidence of intestinal lymphangiectasia of the small bowel. Videocapsule endoscopy may be proposed to confirm intestinal lymphangiectasia and to precise their localization when gastroscopy is not conclusive.

    Intermittent fasting prolongs the lifespan and unlike intense stress provides health benefits. Given the role of the immunoglobulin A (IgA) in the intestinal homeostasis, the aim of this study was to assess the impact of intermittent fasting plus intense stress on secretory IgA (SIgA) production and other mucosal parameters in the duodenum and ileum. Two groups of six mice, with intermittent fasting or fed ad libitum for 12weeks, were submitted to a session of intense stress by a bout of forced swimming. Unstressed ad libitum fed or intermittently fasted groups were included as controls. After sacrifice, we evaluated intestinal SIgA and plasma adrenal hormones, lamina propria IgA+ plasma-cells, mRNA expression of polymeric immunoglobulin receptor, α- and J-chains in the liver and intestinal mucosa, as well as pro- (tumor necrosis factor-α, interleukin-6 and Interferon-γ) and anti- (interleukin-2, -4, -10 and transforming growth factor-β) inflammatory cytokines in mucosal samples. Under intense stress, intermittent fasting down- or up-modulated the levels of most parameters in the duodenum and ileum, respectively while up-regulated corticosterone levels without affecting epinephrine. Our data suggest intermittent fasting plus intense stress elicited neuroendocrine pathways that differentially controlled IgA and pIgR expression in duodenum and ileum. These findings provide experimental foundations for a presumable impact of intermittent fasting under intense stress on the intestinal homeostasis or inflammation by triggering or reducing the IgA production in ileum or duodenum respectively.

    Aortoduodenal syndrome is a rare complication of an abdominal aortic aneurysm wherein the aneurysm sac obstructs the patient\\'s duodenum. It presents with the symptoms of an upper gastrointestinal tract obstruction and requires surgical intervention to relieve it. Previously, gastric bypass surgery was advocated, but now aortic replacement is the mainstay of treatment. We report a case of a 67-year-old woman whose aortoduodenal syndrome was successfully managed and review the literature on this topic.

  9. Application of genomic densitometry for calculating the relative population of Escherichia Coli in the intestine of broiler chicks

    2009-05-01

    Full Text Available In this study, the densitometry technique for calculating of the relative population of Escherichia coli in various segments of the intestine of broiler chicks was evaluated. Following preparation of the intestinal contents, the process of extraction and purification of DNA from the contents of duodenum, jejunum, ileum and cecum was undertaken. A specific polymerase chain reaction (PCR using two pairs of primers was employed to detect Escherichia coli and total bacteria present in the gastrointestinal tract of the chicks. Specific bands of E.coli were obtained using densitometry and Gel Proc Analyzer software based on linear regression with extrapolation. E.coli populations at different ages were also determined in various segments of the gastrointestinal tract of the chicks. The Results of this experiment indicated that 0.000004%, 0.07%, 0.64% and 2.51% of total bacteria present in the duodenum, jejunum, ileum and cecum respectively consisted of E.coli. Also, E.coli constitutes 1.76, 0.01 and 0.80% of the total intestinal bacteria of chicks at 4, 14 and 30 days of age respectively. Furthermore, it was shown that at 4 days of age, 0.30, 2.05 and 3.97% of the total bacteria present in the jejunum, ileum and cecum respectively were from E.coli species and this bacteria was absent in the duodenum. At 14 days of age these figures were 0.000009%, 0.00011% and 0.08% respectively while at 30 days of age 0.00011%, 0.009% and 2.40% of all bacteria in the duodenum, ileum and cecum were E.coli species and this bacteria was absent in the jejunum. In conclusion, the densitometry method based on PCR results can be regarded as a useful tool for densitometry the relative population E.coli in the gastrointestinal tract of poultry.

    The Briston strain of Eimeria dispersa Tyzzer, 1929 was isolated originally from a commercial turkey flock from Briston, Norfolk, UK. A single oocyst-derived line of E. dispersa was propagated and used to re-describe biological and morphological features of E. dispersa in the turkey. Oocysts of the Briston strain measured 26 ± 1.1 μm (24-28) by 21 ± 1 μm (19-23); these were larger than oocysts described originally by Tyzzer in 1929 (22.75 by 18.84 μm) but within dimensions (26.07 by 21.04 μm) reported by Hawkins (1952) in his description of E. dispersa isolated from turkeys. In the present study, endogenous development started mainly in duodenum and upper jejunum and then spread down toward the lower jejunum. A few parasites were detected in the ileum beginning 96 h post-infection; only few gamonts were observed in the cecal neck area at 120 h, and no parasites were detected in cecal pouches or rectum. Four asexual generations were observed before the start of gametogony, and only one large type of first generation meront was detected in duodenum and upper jejunum at 32 h. This strain has a prepatent period of 120 h. The Briston strain of E. dispersa is a mildly pathogenic coccidium. Duodenum and jejunum of infected birds were slightly dilated and paler in color than of uninfected controls. There was whitish green mucoid material in the lumen of the duodenum and jejunum. The mucosa looked slightly congested and edematous with a few scattered petechial hemorrhages.

    Purpose: Uncontrolled local growth is the cause of death in ∼30% of patients with unresectable pancreatic cancers. The addition of standard-dose radiotherapy to gemcitabine has been shown to confer a modest survival benefit in this population. Radiation dose escalation with three-dimensional planning is not feasible, but high-dose intensity-modulated radiation therapy (IMRT) has been shown to improve local control. Still, dose-escalation remains limited by gastrointestinal toxicity. In this study, the authors investigate the potential use of double scattering (DS) and pencil beam scanning (PBS) proton therapy in limiting dose to critical organs at risk. Methods: The authors compared DS, PBS, and IMRT plans in 13 patients with unresectable cancer of the pancreatic head, paying particular attention to duodenum, small intestine, stomach, liver, kidney, and cord constraints in addition to target volume coverage. All plans were calculated to 5500 cGy in 25 fractions with equivalent constraints and normalized to prescription dose. All statistics were by two-tailed paired t-test. Results: Both DS and PBS decreased stomach, duodenum, and small bowel dose in low-dose regions compared to IMRT (p < 0.01). However, protons yielded increased doses in the mid to high dose regions (e.g., 23.6–53.8 and 34.9–52.4 Gy for duodenum using DS and PBS, respectively; p < 0.05). Protons also increased generalized equivalent uniform dose to duodenum and stomach, however these differences were small (<5% and 10%, respectively; p < 0.01). Doses to other organs-at-risk were within institutional constraints and placed no obvious limitations on treatment planning. Conclusions: Proton therapy does not appear to reduce OAR volumes receiving high dose. Protons are able to reduce the treated volume receiving low-intermediate doses, however the clinical significance of this remains to be determined in future investigations.

    Full Text Available BACKGROUND: Adult Clonorchis sinensis live in the bile duct and cause clonorchiasis. It is known that the C. sinensis metacercariae excyst in the duodenum and migrate up to the bile duct through the common bile duct. However, no direct evidence is available on the in vivo migration of newly excysted C. sinensis juveniles (CsNEJs. Advanced imaging technologies now allow the in vivo migration and localization to be visualized. In the present study, we sought to determine how sensitively CsNEJs respond to bile and how fast they migrate to the intrahepatic bile duct using PET-CT. METHODOLOGY/PRINCIPAL FINDINGS: CsNEJs were radiolabeled with (18F-fluorodeoxyglucose ((18F-FDG. Rabbits with a gallbladder contraction response to cholecystokinin-8 (CCK-8 injection were pre-screened using cholescintigraphy. In these rabbits, gallbladders contracted by 50% in volume at an average of 11.5 min post-injection. The four rabbits examined were kept anesthetized and a catheter inserted into the mid duodenum. Gallbladder contraction was stimulated by injecting CCK-8 (20 ng/kg every minute over the experiment. Anatomical images were acquired by CT initially and dynamic PET was then carried out for 90 min with a 3-min acquisition per frame. Twelve minutes after CCK-8 injection, about 3,000 (18F-FDG-labeled CsNEJs were inoculated into the mid duodenum through the catheter. Photon signals were detected in the liver 7-9 min after CsNEJs inoculation, and these then increased in the whole liver with stronger intensity in the central area, presenting that the CsNEJs were arriving at the intrahepatic bile ducts. CONCLUSION: In the duodenum, CsNEJs immediately sense bile and migrate quickly with bile-chemotaxis to reach the intrahepatic bile ducts by way of the ampulla of Vater.

    A size 12 French radiopaque catheter, 135 cm long, suitable for rapid duodenal and jejunal intubation, is described. Its size and flexibility enable it to be passed with ease through the nose, stomach and duodenum. A guide wire is used to act as a stiffener as the catheter is passed through the stomach. The catheter is suitable for infusing barium directly into the small intestine and for performing hypotonic duodenography. The technique for duodenal and jejunal intubation is discussed. (author)

    The investigation was devised to determine whether changes noted in the unirradiated duodenum and colon of single rats after X-irradiation of only the exteriorized rat jejunum and ileum are mediated by a systemic humoral factor. Littermate Holtzman male rats were joined in parabiosis and one month later, the temporarily exteriorized jejunum and ileum of one member was exposed to 1.000 R of 250 kVp X-irradiation. Two days after X-irradiation, and 1, 12 and 24 h after 1 μCi/g bodyweight 3 H-thymidine was injected i.p. rats were sacrificed and appropriate tissues removed. Single rats which had the exteriorized jejunum and ileum irradiated were studied from 1-3 days after irradiation. Crypt cell migration rates were determined employing autoradiography. Tritium content and columnar cell migration rate in duodenum and colon of unirradiated rats compared to irradiated rats indicated that irradiation of one member of the pair had no effect on tritium incorporation or epithelial cell migration in the duodenum or colon of the unirradiated partner. Epithelial cell proliferation and crypt cell migration were increased in unirradiated duodenum and colon of single intestine-irradiated rats. Essentially the same changes were seen in the irradiated member of a parabiotic pair, but none of these changes were noted in the unirradiated member. The absence of stimulation in the unirradiated parabiont suggests that either a systemic humoral factor is not present after X-irradiation or is not present in sufficient concentration to be detected by these methods.

    Background: Activation of the ileal brake through the delivery of nutrients into the distal small intestine to promote satiety and suppress food intake provides a new target for weight loss. Evidence is limited, with support from naso-ileal lipid infusion studies. Objective: The objective of the study was to investigate whether glucose infused into the duodenum and ileum differentially alters appetite response, food intake, and secretion of satiety-related gastrointestinal peptides. Design: Fourteen healthy male participants were randomly assigned to a blinded 4-treatment crossover, with each treatment of single-day duration. On the day before the intervention (day 0), a 380-cm multilumen tube (1.75-mm diameter) with independent port access to the duodenum and ileum was inserted, and position was confirmed by X-ray. Subsequently (days 1-4), a standardized breakfast meal was followed midmorning by a 90-min infusion of isotonic glucose (15 g, 235 kJ) or saline to the duodenum or ileum. Appetite ratings were assessed with the use of visual analog scales (VASs), blood samples collected, and ad libitum energy intake (EI) measured at lunch, afternoon snack, and dinner. Results: Thirteen participants completed the 4 infusion days. There was a significant effect of nutrient infused and site (treatment × time, P appetite, and decreased ad libitum EI at a subsequent meal. Although glucose to the duodenum also suppressed appetite ratings, eating behavior was not altered.

    2015-07-01

    Purpose: The midventilation (midV) approach can be used to take respiratory-induced pancreatic tumor motion into account during radiation therapy. In this study, the dosimetric consequences for organs at risk and tumor coverage of using a midV approach compared with using an internal target volume (ITV) were investigated. Methods and Materials: For each of the 18 patients, 2 treatment plans (25 × 2.0 Gy) were created, 1 using an ITV and 1 using a midV approach. The midV dose distribution was blurred using the respiratory-induced motion from 4-dimensional computed tomography. The resulting planning target volume (PTV) coverage for this blurred dose distribution was analyzed; PTV coverage was required to be at least V{sub 95%} >98%. In addition, the change in PTV size and the changes in V{sub 10Gy}, V{sub 20Gy}, V{sub 30Gy}, V{sub 40Gy}, D{sub mean} and D{sub 2cc} for the stomach and for the duodenum were analyzed; differences were tested for significance using the Wilcoxon signed-rank test. Results: Using a midV approach resulted in sufficient target coverage. A highly significant PTV size reduction of 13.9% (P<.001) was observed. Also, all dose parameters for the stomach and duodenum, except the D{sub 2cc} of the duodenum, improved significantly (P≤.002). Conclusions: By using the midV approach to account for respiratory-induced tumor motion, a significant PTV reduction and significant dose reductions to the stomach and to the duodenum can be achieved when irradiating pancreatic tumors.

    The present study investigated the effects of xanthophylls (containing 40 % of lutein and 60 % of zeaxanthin) on proinflammatory cytokine (IL-1β, IL-6, interferon (IFN)-γ and lipopolysaccharide-induced TNF-α factor (LITAF)) and anti-inflammatory cytokine (IL-4 and IL-10) expression of breeding hens and chicks. In Expt 1, a total of 432 hens were fed diets supplemented with 0 (as the control group), 20 or 40 mg/kg xanthophylls (six replicates per treatment). The liver, duodenum, jejunum and ileum were sampled at 35 d of the trial. The results showed that both levels of xanthophyll addition decreased IL-1β mRNA in the liver and jejunum, IL-6 mRNA in the liver, IFN-γ mRNA in the jejunum and LITAF mRNA in the liver compared to the control group. Expt 2 was a 2 × 2 factorial design. Male chicks hatched from 0 or 40 mg/kg xanthophyll diet of hens were fed a diet containing either 0 or 40 mg/kg xanthophylls. The liver, duodenum, jejunum and ileum were collected at 0, 7, 14 and 21 d after hatching. The results showed that in ovo xanthophylls decreased proinflammatory cytokine expression (IL-1β, IL-6, IFN-γ and LITAF) in the liver, duodenum, jejunum and ileum and increased anti-inflammatory cytokine expression (IL-4 and IL-10) in the liver, jejunum and ileum mainly at 0-7 d after hatching. In ovo effects gradually vanished and dietary effects began to work during 1-2 weeks after hatching. Dietary xanthophylls modulated proinflammatory cytokines (IL-1β, IL-6 and IFN-γ) in the liver, duodenum, jejunum and ileum and anti-inflammatory cytokine (IL-10) in the liver and jejunum mainly from 2 weeks onwards. In conclusion, xanthophylls could regulate proinflammatory and anti-inflammatory cytokine expression in different tissues of hens and chicks.

    A new radioimmunoassay which allows the measurement of the rat vasoactive intestinal polypeptide, was performed. VIP is present in the whole digestive tract of rat, mainly between the duodenum and the colon. 1.5% of the total VIP is present in brain. The VIP-like immunoreactivity appears to correspond to biologically active molecule since a radioreceptorassay using liver plasma membranes as the target tissue, gives the same results as the radioimmunoassay [fr

    The purpose of this study was to describe the ultrasonographic features and assess the diagnostic value of sonography in the evaluation of children with Henoch-Schonlein purpura. Between October 1993, and Febuary 1998, 67 children with Henoch-Schonlein purpura underwent abdominal ultrasonography, which in 13 was used for follow up. Bowel wall thickness and location, pattern of color Doppler signal in the thickened bowel wall, the size and location of enlarged mesenteric lymph node and the presence of ascites were evaluated. In 42 cases(63%), sonographic findings were positive, and indicated mesenteric lymphadenopathy(n=3D21), small bowel wall thickening(n=3D20), and ascites(n=3D17). Thickened bowels were demonstrated at the ileum in 11 cases, the jejunum in five, the duodenum in one, and combined wall thickening at the duodenum and jejunum in two;thickening of the duodenum and ileum was seen in one case. Thickness varied from 3 to 10 mm(mean:6.5 mm). On follow-up sonography, regression of bowel wall thickening was observed earlier than that of mesenteric lymphadenopathy or ascites, and correlated well with improved abdominal symptoms. Abdominal ultrasonographic manifestations of Henoch-Schonlein purpura were bowel wall thickening, mesentric lymphadenopathy and ascites. Sonography was a simple and useful method for the evaluation of gastrointestinal manifestation of Henoch-Schonlein purpura.=20

    SMAS (Superior Mesenteric Artery Syndrome) is a disease caused by a chronic obstruction of the duodenum (transverse portion ), which is hardly detectable. However, it is known that when the superior mesenteric artery and abdominal aorta form a narrow angle, that the transverse portion of the duodenum is pressed down between the superior mesenteric artery and the abdominal aorta, and that this can lead to obstruction of the duodenum. Measuring this angle is a complicated job using conventional angiography, and results often turns out to be inaccurate. In addition, no attempt has been made to determine the value of this angle in Koreans. In this study, we conducted abdominal CT angiography using MIP (maximum intensity projection) on patients with no clinical evidence of SMAS in order to determine the angle at which the superior mesenteric artery branches from the abdominal aorta by using PC based software (Rapidia ver. 1.2) for the image reconstruction. Accordingly, we found that the mean angle between the abdominal aorta and the superior mesenteric artery was 50.05 ± 15.87 .deg. on average, and that the angle in men (53.64 ± 16.57 .deg.) is higher than in women (46.46 ± 14.98 .deg. ). We hope that the angles determined by our study will serve as an important indicator for detecting SMAS

    AIM: Oral contrast media are commonly given prior to computed tomography (CT) examination of the upper abdomen. Although positive oral contrast media are normally used, there is increasing interest in using negative agents such as water and less commonly fat density products. The aim of this study was to compare a positive oral contrast medium, water, and a diluted emulsion of arachis oil (Calogen[reg], a fat density food supplement) for assessment of the upper abdomen. MATERIALS AND METHODS: Seventy-one patients referred for upper abdominal CT were randomized to receive either 500 ml water, 2% sodium diatrizoate or a dilute suspension of Calogen[reg]. The CT images were scored independently by three radiologists. Distension and anatomical identification was assessed for the stomach, duodenum and jejunum; with anatomical identification recorded for the pancreas, retroperitoneum, liver, gallbladder and spleen. RESULTS: Dilute Calogen[reg] produced a significant improvement (P < 0.01) in distension and anatomical visualization of the stomach and proximal duodenum. Only minimal differences were demonstrated between the three contrast media for visualization of more distal small bowel or identification of the other upper abdominal viscera. Significantly more artifacts were caused by positive contrast media than with the Calogen[reg] mixture. CONCLUSION: A dilute suspension of Calogen[reg] as an oral contrast medium is recommended when disease is suspected within the stomach or proximal duodenum. Ramsay, D.W. et al. (2001)

    A technique for duodenal alimentation (needle catheter duodenostomy) of birds was developed, using the domestic pigeon (Columba livia) as the experimental model. A needle catheter was inserted into the descending duodenum of 5 pigeons and was secured to the body wall and dorsum of each bird. A liquid diet was administered daily (in equal amounts of 0, 4, 8, 12, and 16 hours) for 14 days without adverse effects. On day 15, the catheters were removed, and the birds immediately resumed normal consumption of a pigeon ration and water diet. Although 4 of the 5 birds had minor weight loss, dietary alterations probably could be used on an individual basis to alleviate this problem. After oral alimentation was resumed, the 5 birds exceeded their initial body weight within 7 days. Four weeks after catheter removal, positive-contrast radiographic evaluations indicated that the duodenum of each pigeon appeared normal. Needle catheter duodenostomy was a viable method of alimentation in the domestic pigeon. This technique should be applicable for other avian species requiring bypass of the upper gastrointestinal tract proximal to the region of catheter insertion in the duodenum.

    Full Text Available Abstract Introduction Heterotopic pancreatic cancer in the duodenum is a very rare disease. Only twelve cases have been reported worldwide to date. We report a rare case of malignant transformation of heterotopic pancreas (Heinrich type III in the duodenum with long-term survival of the patient, and review the 12 cases in the literature. Case presentation A 75-year-old Japanese man was admitted to our hospital complaining of nausea and vomiting. Endoscopy and upper gastrointestinal contrast study showed marked duodenal stenosis. A pylorus-preserving pancreaticoduodenectomy was performed. Histopathological examination of the surgically resected specimen showed malignant transformation of heterotopic pancreas (Heinrich type III in the duodenum. The postoperative course was uneventful, and the patient was discharged from the hospital on postoperative day 30. He is well and shows no signs of recurrence at the time of writing, six years after the surgery. Conclusion Adenocarcinoma arising within the heterotopic pancreas appears to be rare. It is difficult to obtain a correct diagnosis preoperatively. The management of heterotopic pancreas depends on the presence or absence of symptoms. If the patient is asymptomatic or benign, conservative treatment with regular follow-up is recommended. When the patient is symptomatic or there is a suspicion of malignancy, surgical management with intra-operative frozen section diagnosis is indicated.

    The rare combination of intestinal lymphangiectasia with malrotation of the duodenum in a child of three months of life is described. Basing on the literature review only 3 similar cases were described in the world practice. The boy with protein-losing enteropathy was examined at Moscow Scientific Centre of Children's Health. The child had vomiting, diarrhea, loss in body weight, hypoproteinemia, lymphopenia. The infectious nature of the disease was excluded. It had been suggested the Waldman desease (primary intestinal lymphangiectasia). The prognosis for such disease is unfavorable. An examination of the child was continued against the backdrop of ongoing symptomatic therapy. Complete physical examination included monitoring laboratory blood tests, X-ray examination with contrast, CT-scan, gastroduodenoscopy with biopsy of the mucosa of the small intestine. Malrotation duodenum with the recurrent mid-gut volvulus with the development of secondary intestinal lymphangiectasia was diagnosed. Modern methods of examination and multidisciplinary approach made it possible to diagnose the case. Operation to eliminate fixation duodenum resulted in the recovery of the patient. At the present time the child grows and develops according to age and does not require treatment. The prognosis for this disease is regarded as favorable.

    Full Text Available The function of immune system of poultry has a significant impact on poultry husbandry sustainabi¬lity. Therefore the aim of this study was to investigate the effect of lactic acid bacteria administered with enrofloxacin or doxycycline on expression levels of antimicrobial peptide cathelicidin-3 (CATH3 at mRNA level in the duodenum, jejunum and liver of broilers. A day-old Ross (n=24 and Duc (n=24 chickens were included in experiments with enrofloxacin and doxycycline, respectively. They were divided into four groups (n=6 for each experiment: control, supplemented with probiotics (15 days via feed, 5 days after hatching, treated with either enrofloxacin or doxycycline (10 mg.kg-1 for 5 days, via drinking water and treated with antibiotic and probiotics. Expression levels of CATH3 mRNA in liver, duodenum and jejunum were determined by RT-PCR and were statistically evaluated by Mann-Whitney test.Administration of probiotics led to insignificant down-regulation of CATH3 mRNA in the investigated tissues. The combination of doxycycline with probiotics led to statistically significant down-regulation of CATH3 mRNA in the duodenum (P<0.01. Statistically significant up-regulation of mRNA of the studied gene was found in the jejunum of enrofloxacin treated Ross chickens. The data suggest the existence of an interaction between antibiotics and innate immunity. Further evaluation in infected poultry would shed more light on the pharmacodynamics of antibacterials.

    Purpose: Groove pancreatitis is a rare focal form of chronic pancreatitis that occurs in the pancreaticoduodenal groove between the major and minor papillae, duodenum and pancreatic head. Radiologic appearance and clinical presentation can result in suspicion of malignancy rendering pancreaticoduodenectomy inevitable. This study reports dual phase CT findings in a series of 12 patients with pathology proven groove pancreatitis. Materials and methods: Retrospective review of preoperative CT findings in 12 patients with histologically proven groove pancreatitis after pancreaticoduodenectomy. Size, location, attenuation, presence of mass or cystic components in the pancreas, groove and duodenum, calcifications, duodenal stenosis and ductal changes were recorded. Clinical data, laboratory values, endoscopic ultrasonographic and histopathological findings were collected. Results: Soft tissue thickening in the groove was seen in all patients. Pancreatic head, groove and duodenum were all involved in 75% patients. A discrete lesion in the pancreatic head was seen in half of the patients, most of which appeared hypodense on both arterial and venous phases. Cystic changes in pancreatic head were seen in 75% patients. Duodenal involvement was seen in 92% patients including wall thickening and cyst formation. The main pancreatic duct was dilated in 7 patients, with an abrupt cut off in 3 and a smooth tapering stricture in 4. Five patients had evidence of chronic pancreatitis with parenchymal calcifications. Conclusion: Presence of mass or soft tissue thickening in the groove with cystic duodenal thickening is highly suggestive of groove pancreatitis. Recognizing common radiological features may help in diagnosis and reduce suspicion of malignancy.

    Full Text Available The analysis of anamnestic and clinical indices, and also morphological investigation of biopsy materials of mucous coat of stomach and duodenum in children with chronic gastroduodenitis of different etiology including lambliasis invasion is carried out with the purpose of detecting features of clinicopathologic presentations of chronic gastroduodenitis in children with and without lambliasis invasion. Material and methods. 100 patients (50 children with confirmed lambliasis invasion and 50 patients without lambliasis invasion aged from 2 up to 16 were under observation. The material for histologic study was received as a result of fibrogastroduodenoscopy carried out with target biopsy of fundic, antrum and duodenum mucosa. Results. As a result of the findings moderate pains sited in epigastric and periumbilical regions are characteristic for children with lambliasis invasion; irradiation and cramping characteristics of pains are typical. Conclusion. Manifestation of pains is not connected with the time of day and food intake, manifestation of seasonal prevalence is not typical as well, and progression of inflammatory process in the mucous coat of the stomach and duodenum is declared itself as a diffuse gastritis of the fundic part, a diffuse gastritis of the antral part, subatrophic duodenitis with cyst formation of Brunner's glands, and also the presence of eosinophilic leucocytes in the cellular infiltrate

    Two fistulated pigs weighing between 15kg and 54kg were given experimental diets containing 15 N-labelled dried whey. The labelled experimental diets were given once only. Samples of the digesta were taken from the duodenum and terminal ileum at various intervals of time up to 48h after feeding the labelled protein feed. The digesta were separated into the four following fractions: Residue on centrifugation, proteins, peptides and free amino acids. The secretion of endogenous nitrogen in the duodenum was 12.5g/24h in pigs having a live weight of 50kg. The endogenous nitrogen was found to be relatively uniformly distributed among the four fractions. The rate of secretion of endogenous nitrogen showed a continuous decrease during 24h. The secretion of endogenous nitrogen in the terminal ileum was 54 to 60mg of nitrogen per kilogram live weight. After passage through the small intestine the greater part of the free amino acids in digesta was of exogenous origin. In the protein fraction most came from endogenous proteins. A true absorption of 17% of nitrogen was determined in the duodenum. The amount of nitrogen absorbed in the terminal part of the small intestine was, on average, 90% relative to the nitrogen intake. The true digestibility calculated with the amount of 15 N in food and faeces was 98%. (author)

    Full Text Available Traumatic intramural hematoma of the duodenum is a rare cause of acquired duodenal obstruction in children, and a high degree of suspicion is therefore required to make an early and accurate diagnosis. We report a 6-year-old boy whose epigastrium was impacted by the handlebar of his bicycle during a traffic accident. The boy then experienced epigastralgia. Six days later, progressive bilious vomiting suggestive of gastrointestinal obstruction was noted. Imaging studies revealed a large hematoma extending from the fourth portion of the duodenum to the jejunum. Conservative methods of treatment failed to manage his condition. He underwent laparoscopic surgery to evacuate the hematoma. We also report a case of duodenal obstruction in a previously healthy 2-year-old girl who presented for the first time with acute symptoms of proximal intestinal obstruction. Contrast examinations showed apparent barium retention over the stomach and proximal duodenum. She underwent surgery due to persistent obstruction, and a mushroom-like foreign body was detected embedded in the orifice of the windsock duodenal web. After duodenoduodenostomy and removal of the bezoar, she had a smooth recovery and tolerated feeding well. We conclude that blunt abdominal trauma and incomplete duodenal obstruction, such as that caused by duodenal web, should be considered as possible causes of acquired proximal gastrointestinal obstruction in previously healthy children, despite their rarity.

    1. Contractile and spike activity in the conscious dog were recorded from strain gauge force transducers and electrodes chronically implanted on the antrum, duodenum and jejunum. The pattern of activity was related to the time elapsed after feeding a daily meal, both in intact dogs and in dogs with antro-jejunal or oesophago-duodenal anastomoses. 2. From 8 to 10 h after feeding, transient reductions of the continuous antral spiking activity were recorded while phases of regular spiking activity (RSA) and contractions developed on the proximal intestine. 3. About 18 h after feeding, the post-prandial antral activity became intermittent, each period of contractions being accompanied by the duodenal development of a RSA phase. 4. The RSA phases were still initiated on the duodenum after an antro-jejunal anastomosis and after gastrectomy. 5. It is concluded that phases of RSA of the migrating myoelectric complex are initiated in the proximal part of the small intestine rather than in the stomach. It is suggested that the RSA phase exerts an inhibitory effect on the antrum which may serve to reduce the flow of digesta through the pylorus when the ability of the duodenum to receive chyme is restricted.

    Characterisation and identification of peptides (800 to 5000 Da) generated by intestinal digestion of fish or meat were performed using MS analyses (matrix-assisted laser desorption ionisation time of flight and nano-liquid chromatography electrospray-ionisation ion trap MS/MS). Four pigs fitted with cannulas at the duodenum and jejunum received a meal exclusively made of cooked Pectoralis profundus beef meat or cooked trout fillets. A protein-free meal, made of free amino acids, starch and fat, was used to identify peptides of endogenous origin. Peptides reproducibly detected in digesta (i.e. from at least three pigs) were evidenced predominantly in the first 3 h after the meal. In the duodenum, most of the fish- and meat-derived peptides were characteristic of a peptic digestion. In the jejunum, the majority of peptides appeared to result from digestion by chymotrypsin and trypsin. Despite slight differences in gastric emptying kinetics and overall peptide production, possibly in relation to food structure and texture, six and four similar peptides were released after ingestion of fish or meat in the duodenum and jejunum. A total of twenty-six different peptides were identified in digesta. All were fragments of major structural (actin, myosin) or sarcoplasmic (creatine kinase, glyceraldehyde-3-phosphate dehydrogenase and myoglobin) muscle proteins. Peptides were short ( digestion, some of them can be reproducibly observed in intestinal digesta.

    Full Text Available Background. Injuries of the duodenum at the level of aortomesenteric clamp (segment D3 are with a high incidence of death due to the development of fistula and peritonitis. In three successfully managed cases, we applied the biliary surgery method. Case reports. All three cases were with the injuries of D3 duodenal segment. The first patient suffered from the blast perforation of duodenum at the level of the aortomesenteric clamp which occurred at the 7th day after the injury. The second patient suffered from the duodenal injury caused in a traffic accident. The third patient suffered from an iatrogenic injury at the beginning of D3 duodenal segment inflicted during ureterolithotomy. The described surgical procedure included basically the suture to narrow the site of the injury, then lateroterminal anastomosis with the Roux-en-Y jejunal flexure and, finally, the placement of a silicone prosthesis starting from the duodenum through the site of injury and the Roux-en-Y out. Octreotide and the total parenteral nutrition were administered to the patients postoperatively. Conclusion. The use of the releasing silicone prosthesis in all three patients provided the repair of the site of the injury with anastomosed Reux-en-Y jejunum.

    Full Text Available Bouveret's syndrome is a high mechanical obstruction due to impaction of a gallstone into the duodenum, through a cholecystoduodenal fistula. It belongs to a larger group of gallstone ileus, a disease which occurs after developing a fistula between the gallbladder and the gastrointestinal tract. This is a rare complication of gallstones but because it appears in elderly people, it has a high morbidity and mortality. Patients have various symptoms and the treatment is individualized. We present here a case of a 67 years old patient, admitted in emergency, presenting symptoms of high bowel obstruction, with onset 5 days before admission. Abdominal ultrasound reveals a 5 cm stone that seems to be in the gallbladder, gastric stasis and at gastroscopy appears a foreign body impacted in the duodenum. After a short preparation the patient underwent surgery. We found a dilated stomach and a large cholecystoduodenal fistula with an impacted gallstone in the duodenum. We performed one stage surgery: cholecystectomy, extraction of the stone and suturing of the fistula. We reestablished the continuity of the intestinal tract. We performed also an ileostomy for feeding the patient and protecting the anastomoses. The postoperative evolution was favorable.

    The secretion of the goblet cells in the intestine of Trachemys scripta elegans was studied in situ by histochemical methods to analyze the diversity of sugar chains, with particular regard to the acidic glycans. Conventional histochemical stains (Periodic acid-Schiff, Alcian Blue pH 2.5, High Iron Diamine) and binding with ten FITC-labelled lectins combined with chemical and enzymatic pre-treatments were used to characterize the oligosaccharidic chains. The intestine can be divided into three regions, i.e. a duodenum, a small intestine and a large intestine. Goblet cells were observed in all the three tracts and presented an acidic secretion. WGA, LFA, PNA and SBA binding was observed only after desulfation. Glycans secreted by the three tracts consist mainly of sulfosialomucins with 1,2-linked fucose, mannosylated, glucosaminylated and subterminal galactosyl/galactosaminylated residuals. Differences among tracts are quantitative rather than qualitative, with sulfated, galactosaminylated and glycosaminylated residuals increasing from duodenum to large intestine, and galactosylated and fucosylated residuals showing an opposite trend. Variation is observed also between apices and bases of villi in both duodenum and small intestine, where sulphation decreases from the base to the apex and glycosylation shows an opposite trend. Functional implication of these findings is discussed in a comparative context. Copyright © 2017 Elsevier Ltd. All rights reserved.

  1. Unusual Upper Gastrointestinal Bleeding due to Late Metastasis from Renal Cell Carcinoma: A Case Report

    2004-03-01

    Full Text Available A case of recurrent massive upper gastrointestinal bleeding originating from metastatic renal cell carcinoma is reported. A 63-year-old woman underwent right nephrectomy 9 years previously and experienced no recurrence during follow-up. A gradually enlarging ulcerative tumor over the bulb of the duodenum and four subsequent episodes of massive bleeding from this tumor occurred between June 2001 and March 2002. The patient underwent surgery in April 2002 for intractable bleeding from the tumor. Renal cell carcinoma metastasis to the duodenum was confirmed from the surgical specimen. Upper gastrointestinal bleeding due to malignancy is very rare and the duodenum is the least frequently involved site. Furthermore, a solitary late renal cell carcinoma metastasis 9 years after a nephrectomy is extremely uncommon. This case suggests that life-long follow-up of renal cell carcinoma patients is necessary, owing to unpredictable behavior and the possibility of long disease-free intervals. In nephrectomized patients suffering from gastrointestinal bleeding, complete evaluation, especially endoscopic examination, is indicated. The possibility of late recurrent renal cell carcinoma metastasis to the gastrointestinal tract should be kept in mind, although it is rare. If the patient is fit for surgery, metastatectomy is the first choice of treatment.

    Full Text Available The objective of the study was to estimate the prevalence and to describe the lesions and signs found in an outbreak of Hexamita meleagridis in three turkey farms in Yucatan, Mexico. Three hundred randomly selected, turkeys were sacrificed and their intestines explored for lesions associated with H. Meleagridis infection. Also, gut content, feces samples and fresh intestine smears were taken to determine the presence of H. Meleagridis parasites. Macroscopic lesions such as the presence of congested areas, and watery and foamy content in duodenum, presence of gases, fetid odor and the presence of watery and yellowish feces in the caeca were identified. The overall prevalence of H. Meleagridis was 25.3% and there was not association of the parasite with sex, age or farm. However, the thickening of some sections of the duodenum (52.3%, the presence of congested areas (23%, the watery and yellowish content of the duodenum (24.3%, the presence of gas (21.0%, fetid odor of the content (22.3%, and the watery and yellowish feces of the caeca (20.0% were associated with H. meleagridis Presence of H. meleagridis in those farms was confirmed. Diarrhea signs and intestine lesions observed in the sacrificed turkeys were associated to hexamitiasis infection. Sex, age and farm were not associated with the presence of H. meleagridis.

    Results of surgical treatment of 61 patients with injuries of the duodenum are analyzed. The causes of injuries were stab-incised wounds in 24 patients, missile wound -- in 7, closed abdominal trauma -- in 26, trauma of the duodenum during endoscopic papillosphincterotomy -- in 4. All the patients underwent surgery. Complications were seen in 32 (52.5%) patients, 21 patients died, lethality was 34.4%. Within the first 24 hours since the trauma 7 patients died due to severe combined trauma, blood loss, 54 patients survived acute period of trauma, including 28 patients after open trauma, 26 -- after closed and 4 -- after trauma of the duodenum during endoscopic papillosphincterotomy. Diagnostic and surgical policies are discussed. Results of treatment depending on kind and time of surgery are regarded. It is demonstrated that purulent complications due to retroperitoneal phlegmona, traumatic pancreatitis, pneumonia are the causes of significant number of unfavorable outcomes. Therefore, it is important to adequately incise and drainage infected parts of retroperitoneal fat tissue with two-lumen drainages. Decompression through duodenal tube is the effective procedure for prophylaxis of suture insufficiency and traumatic pancreatitis.

    Patients with pancreatic and/or duodenal trauma often have a high incidence of infectious complications. In this study we attempted to find the most important risk factors for these infections. A retrospective review of the records of 167 patients seen over 7 years (1989 through 1996) at an urban Level I trauma center for injury to the duodenum and/or pancreas was performed. Fifty-nine patients (35%) had isolated injury to the duodenum (13 blunt, 46 penetrating), 81 (49%) had isolated pancreatic trauma (18 blunt, 63 penetrating), and 27 (16%) had combined injuries (two blunt, 25 penetrating). The overall mortality rate was 21 per cent and the infectious morbidity rate was 40 per cent. The majority of patients had primary repair and/or drainage as treatment of their injuries. Patients with pancreatic injuries (alone or combined with a duodenal injury) had a much higher infection rate than duodenal injuries. The patients with duodenal injuries had significantly lower penetrating abdominal trauma indices, number of intra-abdominal organ injuries, and incidence of hypothermia. On multivariate analysis independent factors associated with infections included hypothermia and the presence of a pancreatic injury. Although injuries to the pancreas and duodenum often coexist it is the pancreatic injury that contributes most to the infectious morbidity.

    INTRODUCTION Primer small intestine bezoar is seen rarely. It frequently arises from underlying small intestine pathologies (diverticle, tumor, stricture etc.). We report a very rare case of disopyrobezoar in the duodenal diverticulum, a kind of phytobezoar caused by persimmons, which was treated laparoscopically. PRESENTATION OF CASE The 47-year-old patient applied to polyclinic with complaints of epigastric tenderness, occasional distension, and acid regurgitation. In endoscopical examination, impacted bezoar was determined in the diverticulum in the duodenum. Because it is too hard, it was unable to remove endoscopically. On the abdominal tomography, a smooth-bounded non-homogeneous mass including gas and soft tissue areas in the 2nd portion of the duodenum was detected. A barium meal confirmed the presence of a 5 cm diameter diverticulum on the lateral wall of the second portion of the duodenum. It also showed an intraluminalfilling defect as well as the mottled appearance of the bezoar. Learned from history of the patient, that the patient consumed over persimmon in childhood. DISCUSSION Generally, duodenal diverticles are asymptomatic. Surgical treatment is rarely necessary because of complications such as bleeding, perforation, abdominal pain, bezoar formation. As well as using methods such as gastric lavage, enzymatic dissolution, endoscopical fragmentation in the treatment of phytobezoar, their chances of success are low because its structure is rigid. Usually, surgical intervention is required. CONCLUSION For the treatments of bezoar cases located in the small intestine, laparoscopic surgical method is a safe and feasible method in selected cases.

    Full Text Available An unusual cause of upper gastrointestinal bleeding is described in a previously healthy 45-year-old man who was admitted to hospital with weakness and fatigue, and had experienced an episode of melena two days before admission. His medical and surgical history was unremarkable. Upon admission to hospital, he showed evidence of iron-deficiency anemia, with a hemoglobin concentration of 61 g/L (normal range 135 to 175 g/L, a mean corpuscular volume of 73 fL (normal range 85.0 to 95.0 fL and a ferritin concentration of 1.0 µg/L (normal range in males 15 to 400 µg/L. Upper gastrointestinal endoscopy revealed a 3.5 cm ulcerated submucosal mass in the third portion of the duodenum, for which mucosal biopsies were nondiagnostic. A subsequent endoscopic ultrasound revealed a 2.7×4.0 cm hyperechoic, cystic, submucosal tumour in the third portion of the duodenum. Endoscopic ultrasound-guided fine needle aspiration revealed no malignant cells. The patient eventually underwent a resection of the third portion of his duodenum. Surgical pathology revealed that this tumour was a Brunner’s gland hamartoma, 4.5 cm in its greatest dimension.

  8. NSAID gastropathy and enteropathy: distinct pathogenesis likely necessitates distinct prevention strategies.

    The mechanisms underlying the ability of nonsteroidal anti-inflammatory drugs (NSAIDs) to cause ulceration in the stomach and proximal duodenum are well understood, and this injury can largely be prevented through suppression of gastric acid secretion (mainly with proton pump inhibitors). In contrast, the pathogenesis of small intestinal injury induced by NSAIDs is less well understood, involving more complex mechanisms than those in the stomach and proximal duodenum. There is clear evidence for important contributions to NSAID enteropathy of enteric bacteria, bile and enterohepatic recirculation of the NSAID. There is no evidence that suppression of gastric acid secretion will reduce the incidence or severity of NSAID enteropathy. Indeed, clinical data suggest little, if any, benefit. Animal studies suggest a significant exacerbation of NSAID enteropathy when proton pump inhibitors are co-administered with the NSAID. This worsening of damage appears to be linked to changes in the number and types of bacteria in the small intestine during proton pump inhibitor therapy. The distinct mechanisms of NSAID-induced injury in the stomach/proximal duodenum versus the more distal small intestine likely dictate distinct strategies for prevention. © 2011 The Author.

    Full Text Available This study was conducted to determine the effects of different levels of crude protein (CP supplements to the diet of early-weaned yaks on their growth performance, intestinal development, and immune response. Forty 3-month-old weaned yaks were selected and assigned to four dietary groups (Control, 17, 19 and 21% CP. Dietary CP supplements had a significant effect on average daily gain (ADG, crypt depth (CD (duodenum, jejunum and ileum, villous height (VH (duodenum, jejunum and ileum and CD/VH (jejunum and ileum. Average daily gain, CD (duodenum, jejunum and ileum and VH (ileum showed quadratic increases as the dietary CP increased, whereas CD/VH (jejunum and ileum ratios showed quadratic decreases. Blood urea nitrogen (BUN, glucose (GLU, immunoglobulin G (IgG, IgM, interleukin-1 (IL-1, IL-2, tumor necrosis factor (TNF-α, and interferon (IFN-γ concentrations increased significantly, whereas albumin (ALB, alanine aminotransferase (ALT and aspartate aminotransferase (AST decreased significantly with dietary CP supplements. Dietary CP supplements significantly increased the concentrations of IL-6, TNF-α, IFN-γ and the nuclear factor of activated T cell transcription factor (NFAT for gene expression. As the dietary CP supplements increased, IL-6, IFN-γ and NF-AT gene expression showed quadratic increases. These results showed that the appropriate dietary CP supplementation improved the growth performance and intestinal development of earlyweaned yaks and thus that the CP supplements were beneficial and enhanced the humoral immunity response of yaks.

    Full Text Available Abstract Background The aim of this report was to describe duodenal obstruction caused by a rubber foreign body in a cow. Case Presentation The clinical, biochemical and ultrasonographic findings in a five-year-old Swiss Braunvieh cow with duodenal ileus caused by a calf feeding nipple are described. The main clinical signs were anorexia, ruminal tympany, decreased faecal output and abomasal reflux syndrome. Ultrasonographic examination revealed reticular hyperactivity and a dilated duodenum. A diagnosis of duodenal ileus was made and the cow underwent right-flank laparotomy, which revealed a dilation of the cranial part of the duodenum because of obstruction by a pliable foreign body. This was identified via enterotomy as a calf feeding nipple. The cow was healthy at the time of discharge four days after surgery and went on to complete a successful lactation. Conclusions To our knowledge, this is the first description of duodenal obstruction by a calf feeding nipple. This is an interesting case, which broadens the spectrum of the causes of duodenal ileus, which is usually caused by obstruction of the duodenum by a phytobezoar.

  11. Gastric-emptying tests

    Mechanisms regulating gastric emptying have been characterized through many decades of experimental work. Both central and peripheral mechanisms are important. Central mechanisms are related to the center of vomiting and are probably influenced by psychologic and emotional factors. Peripheral mechanisms are located at both sides of the pylorus. Gastric mechanisms are stimulatory and are triggered mainly by distention of the stomach, although hormonal mechanisms may also participate (gastrin). However, with complex, nutrient-containing meals, the intragastric volume is not the primary determinant of gastric emptying. Inhibitory mechanisms of the gut are more important. The key factors are the pH, osmolality, and nutrient content of the chyme being emptied into the duodenum. Osmotic and pH-sensitive receptors are thought to reside in the duodenum. On the other hand, receptors triggered by nutrients extend much more distally into the duodenum and are sensitive to nutrient composition and load. Protein, carbohydrates, and lipids all inhibit gastric emptying, although the lipids are probably the most potent inhibitors. If the duodenal load or the characteristics of the emptying material are not adequate, inhibitory mechanisms will reduce gastric emptying at the expense of expanding the intragastric volume. It is therefore not possible to dissociate postprandial gastric emptying from postprandial gastric secretion

    Full Text Available Homocysteine is a significant but modifiable risk factor for vascular diseases. As gastrointestinal smooth musculature is similar to blood vessel muscles, we investigated how elevated homocysteine levels affect nitric oxide-mediated neurotransmission in the gut. There is accumulated evidence that a dysfunction of NO neurons in the myenteric plexus may cause various diseases in the gastrointestinal tract such as achalasia, diabetic gastroparesis and infantile hypertrophic pyloric stenosis. In the present study, we aimed to assess the effects of homocysteine on NO-mediated responses in vitro, and to examine the effects of DL-homocysteine thiolactone on the spontaneous motility of rat duodenum and nitrergic neurotransmission. DL-homocysteine thiolactone concentration of 10 μmol/L leads to the immediate increase in tone, amplitude and frequency of spontaneous movements in isolated rat duodenum. L-NAME (30 μmol/L leads to an increase in basal tone, amplitude and frequency of spontaneous contractions. The relaxations induced by EFS were significantly reduced in duodenal segments incubated in DL-homocysteine thiolactone compared with the control group. EFS-induced relaxations were inhibited by L-NAME in both experimental and control groups. These results suggest that a high level of homocysteine causes an important impairment of non-adrenergic non-cholinergic innervation of the rat duodenum.

    Full Text Available A 34-year-old female presented with sudden onset of severe abdominal pain in a flank distribution. A large mass was palpable in the right upper quadrant on physical examination. Abdominal contrast-enhanced computed tomography showed a well-defined, right-sided, retroperitoneal cystic lesion located between the abdominal aorta and the inferior vena cava (IVC. The tumor size was 55 × 58 mm, and it compressed the gallbladder and the duodenum. Upper gastrointestinal radiography revealed a stricture of the second portion of the duodenum by the tumor. T2-weighted magnetic resonance imaging showed that the whole part was hyperintense with hypointense rims, but the inner was partially hypointense. Based on the radiological findings, the preoperative differential diagnosis included retroperitoneal teratoma, Schwannoma, abscess, and primary retroperitoneal tumor. On laparotomy, the tumor was located in the right retroperitoneal cavity. Kocher maneuver and medial visceral rotation, which consists of medial reflection of the upper part of right colon and duodenum by incising their lateral peritoneal attachments, were performed. Although a slight adhesion to the IVC was detected, the tumor was removed safely. Thin-section histopathology examination detected neither tumor tissues nor any tissues such as adrenal gland, ovarian tissue, or endometrial implants. The final pathological diagnosis was idiopathic retroperitoneal hematoma; the origin of the bleeding was unclear. The patient was discharged without any complication 5 days after the operation.

    Full Text Available 【Abstract】A 34-year-old man admitted to our department with complex blunt pancreaticoduodenal injury after a car accident. The wall of the first, second, and third portions of the duodenum was extensively lacerated, and the pancreas was longitudinally transected along the superior mesenteric vein-portal vein trunk. The pancreatic head and the uncinate process were devitalized and the distal common bile duct and the proximal main pancreatic duct were completely detached from the Vater ampulla. The length of the stump of distal common bile located at the cut surface of remnant pancreas was approximately 0.6 cm. A simplified Kausch-Whipple’s procedure was performed after debridement of the devitalized pancreatic head and resection of the damaged duodenum in which the stump of distal common bile duct and the pancreatic remnant were embedded into the jejunal loop. Postoperative wound abscess appeared that eventually recovered by conservative treatment. During 16 months follow-up the patient has been stable and healthy. A simplified pancreaticoduodenectomy is a safe alternative for the Whipple procedure in managing complex pancreaticoduodenal injury in a hemodynamically stable patient.

    A secretin-cholecystokinin test was performed in 103 patients, representing both normal and reduced exocrine pancreatic function. The duodenum was intubated with a triple-lumen tube. The gastric and duodenal contents were aspirated separately and sampled in 10-min. periods. An inert, water-soluble marker ( 58 Co-vitamin B 12 dissolved in isotonic saline) was infused at a constant rate into the duodenum. Exocrine panreatic secretion was stimulated by continuous intravenous infusion of secretin for 60 min. and a combination of secretin and cholecystokinin for another 60 min. The total recovery of the infused marker was 80%. The concentration of marker in the aspriate did not vary significantly between consecutive 10-min. periods during the last 20 min. of the secretin stimulation period, or during the last 50 min. of the combined secretin-cholecystokinin stimulation period, indicating a steady secretion rate into the duodenum. By means of the marker, concentrations in the aspirate, the duodenal volumes were calculated and found to vary significantly less than the aspirated volumes. This finding demonstrates that the duodenal volume calculated from the recovery of an inert marker, is a closer estimate of the true volume than that obtained by the usual apsiration technique without a volume indicator

    Full Text Available This experiment studied the influence of delayed placement (HI and digestible lysine level (DL on the morphometrics of the intestinal mucosa and on the performance of broilers. A total number of 1,705 Cobb 500 male chicks were used in a completely randomized experimental design in a factorial arrangement with four HI (12, 24, 36 and 48h, and two DL level in the starter diet (1.143 and 1.267%, with four replicates and 55 birds per experimental unit. The amino acids methionine-cystine, threonine, and tryptophan were balanced according to the ideal protein (IP concept. Small intestine morphometrics was evaluated using histology slides of the duodenum and jejunum. There was no interaction between HI and DL levels for any of the studied parameters. The 1.143% level of DL promoted better performance results at 21 and 42 days of age, as well as higher duodenum and jejunum crypt depth, and duodenum villi height at 21 days of age. HI negatively influenced the morphometrics of the small intestine during the starter phase, and the performance of broilers up to 42 days of age. There was no effect of the treatments on yolk sac utilization or abdominal fat percentage. It was concluded that the use of 1.143% DL and HI of 12 hours promoted better development of the small intestine mucosa up to 21 days of age, and broiler performance at market age.

    The intestinal permeability of forskolin was investigated using a single pass intestinal perfusion (SPIP) technique in rats. SPIP was performed in different intestinal segments (duodenum, jejunum, ileum, and colon) with three concentrations of forskolin (11.90, 29.75, and 59.90 µg/mL). The investigations of adsorption and stability were performed to ensure that the disappearance of forskolin from the perfusate was due to intestinal absorption. The results of the SPIP study indicated that forskolin could be absorbed in all segments of the intestine. The effective permeability (P (eff)) of forskolin was in the range of drugs with high intestinal permeability. The P (eff) was highest in the duodenum as compared to other intestinal segments. The decreases of P (eff) in the duodenum and ileum at the highest forskolin concentration suggested a saturable transport process. The addition of verapamil, a P-glycoprotein inhibitor, significantly enhanced the permeability of forskolin across the rat jejunum. The absorbed fraction of dissolved forskolin after oral administration in humans was estimated to be 100 % calculated from rat P (eff). In conclusion, dissolved forskolin can be absorbed readily in the intestine. The low aqueous solubility of forskolin might be a crucial factor for its poor oral bioavailability. © Georg Thieme Verlag KG Stuttgart · New York.

    Purpose: To quantify the effect of abdominal compression on duodenal motion during pancreatic radiotherapy. Methods: Seven patients treated for pancreatic cancer were selected for analysis. Four patients were treated with abdominal compression and three without. The duodenum was contoured by the same physician on each CBCT (five CBCTs for patients with compression, four for non-compression patients). CBCTs were rigidly registered using a soft tissue match and contours were copied to the delivered plans which were all radical (BED > 50 Gy). The distance between the duodenum on the planning CT and each CBCT was quantified by calculating the root mean square (RMS) distance. The DVHs of each abdominal compression patient was converted to an EQD2 DVH (alpha/beta = 10) using an in-house tool and volumes receiving at least 25, 35, 45, and 50 Gy were recorded. Results: The maximum variation in duodenal volumes on the CBCTs for the four abdominal compression patients were 19.1 cm{sup 3} (32.8%), 19.1 cm{sup 3} (20.6%), 19.9 cm{sup 3} (14.3%), and 12.9 cm{sup 3} (27.3%) compared to 15.2 cm{sup 3} (17.6%), 34.7 cm{sup 3} (83.4%), and 56 cm{sup 3} (60.2%) for non-compression patients. The average RMS distance between the duodenum on the planning CT and each CBCT for all abdominal compression patients was 0.3 cm compared to 0.7 cm for non-compressed patients. The largest (and average) difference between the planning CT and CBCTs in volume of duodenum receiving more than 25, 35, 45 and 50 Gy for abdominal compression patients was 11% (5%), 9% (3%), 9% (2%), and 6% (1%). Conclusion: Abdominal compression reduces variation in volume and absolute position of the duodenum throughout treatment. This is seen as an improvement but does not eliminate the need to consider dosimetric effects of motion. Abdominal compression is particularly useful in SBRT when only a few fractions are delivered.

    sup(99m)Tc-pylidoxylideneisoleucine (PI) was injected into 106 patients in order to study the mechanism of bile accumulation in the gallbladder in analysis of the visualization time of the gallbladder, intrahepatic bile duct, common bile duct and duodenum on sup(99m)Tc-PI cholescintigrams relating to hepatobiliary function. In cases of normal hepatobiliary function, sup(99m)Tc-PI is rapidly cleared from the blood by hepatocytes and is rapidly excreted through the biliary tree into the duodenum. The common bile duct was seen within 15 min of injection in 93.5% of the patients, the gallbladder within 20 min in 80.8%, the intrahepatic bile duct within 20 min in 96.3%, and the duodenum within 30 min in 58%. Marked accumulation of sup(99m)Tc-PI was noted in the gallbladder within 30 min. In cases of hepatobiliary dysfunction, the duodenum is visualized earlier than the gallbladder and intrahepatic bile duct, and the visualization ratio of the gallbladder and intrahepatic bile duct is decreased with an increased degree of hepatobiliary dysfunction. In regard to serum bilirubin level, the gallbladder was seen up to 3.5 mg%, the intrahepatic bile duct up to 4.0 mg% and the common bile duct up to 22.6 mg%. The duodenum was seen in all but two cases of complete obstruction of the common bile duct. In regard to meal time, marked accumulation of sup(99m)Tc-PI in the gallbladder was seen within 30 min and re-dilatation was seen with in 90 min after the beginning of contraction. In cases of normal hepatobiliary function, the gallbladder was seen in over 70% of the cases more than two hours after meals. This study shows that the hepatobiliary tract can be easily imaged by sup(99m)Tc-PI in proportion to hepatobiliary function and that this agent may be useful in the diagnosis of abnormal hepatobiliary tract and the jaundiced patient with hyperbilirubinemias.

    Full Text Available Introduction. The staye of intestinal microflora affects the work of the whole organism. When composition of normal ibtestine microflora changes, its restoration is required. In our days a wide variety of probiotic drugs are available on the market which can be used to solve this problem. Most bacteria having probiotic properties represent the families Lactobacillus and Bifidobacterium, which have poor resistance to acidic content of the stomach and toxic effects of bile salts. Various studies have clearly shown that in a person with normal acidic and bile secretion, the lactobacilli and bifidobacteria are not detected after the passage through the duodenum, i.e., they perish before reaching the small intestines. In this study we compared the survival of different microorganisms which are contained in 9 probiotic drugs in a model of gastric and intestinal environments. Material and methods. In the laboratory of SI: “Mechnikov Institute Microbiology and Immunology, National Ukrainian Academy Medical Sciences" the in vitro experiments have been evaluated to test the ability of different probiotic bacteria which were contained in 9 probiotic drugs to survive the impact of the model environment of the stomach and duodenum. Bacillus coagulans persistence was evaluated under impact of simulated environment of the stomach and duodenum, it also was assessed by the quantity of CFU by incubation on culture medium. The following were studied: Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus reuteri, Lactobacillus casei, Lactobacillus plantarum, Lactobacillus bulgaricus, Bifidobacterium bifidum, Bifidobacterium longum , Bifidobacterium breve, Bifidobacterium infantis, Bifidobacterium animalis subsp.

    The present study was conducted to investigate the effect of Artemisia argyi aqueous extract (AAE) on antioxidant indexes in the small intestine. A total of 192 Arbor Acre broiler chickens (one-day-old) were randomly divided into 4 treatments with 6 replicates of 8 chickens. These 4 diets were formulated by adding 0, 500, 1,000 and 2,000 mg/kg AAE to the basal diet. The results showed as follows: 1) compared with the control, the total antioxidant capacity (T-AOC) in ileum for the 2,000 mg/kg treatment group was significantly increased at 21 days of age ( P  < 0.05); the T-AOC levels in jejunum and ileum were significantly increased in broilers supplemented with 500 mg/kg AAE at 42 days of age ( P  < 0.05), and the T-AOC levels in jejunum and ileum were significantly improved in 1,000 mg/kg treatment group ( P  < 0.01). 2) At 21 days of age, supplementation of 500 mg/kg AAE significantly increased the catalase (CAT) activity of small intestine, and the glutathione peroxidase (GSH-Px) activity of jejunum was improved ( P  < 0.01), meanwhile, the GSH-Px activity of duodenum and the total superoxide dismutase (T-SOD) activity of duodenum and jejunum were significantly higher than those of the control group ( P  < 0.05); supplementation of 1,000 mg/kg AAE significantly increased the CAT activity of duodenum and ileum and the GSH-Px activity of duodenum and jejunum ( P  < 0.05), and the ileum GSH-Px activity was significantly increased ( P  < 0.01); supplementation of 2,000 mg/kg AAE significantly increased the CAT activity of duodenum and ileum ( P  < 0.05). At 42 days of age, supplementation of 500 mg/kg AAE significantly increased the GSH-Px activity of ileum and the T-SOD activity of duodenum ( P  < 0.05), meanwhile, the T-SOD activity of jejunum was significantly increased ( P  < 0.01); supplementation of 1,000 mg/kg AAE significantly increased the CAT activity of jejunum and the T-SOD activity of ileum ( P  < 0.01), and the GSH

    The Aspergillus niger-derived prolyl endoprotease (AN-PEP) has previously been shown to degrade gluten in healthy subjects when added to an intragastrically infused meal. The current study investigated the efficacy of AN-PEP in a physiological meal setting. In this randomized placebo-controlled crossover study, 18 gluten-sensitive subjects consumed a porridge containing 0.5 g gluten together with two tablets either containing a high or low dose of AN-PEP, or placebo. Gastric and duodenal content was sampled over 180 minutes, and areas under the curve of gluten concentrations were calculated. The primary outcome, i.e. success rate of high dose AN-PEP defined as at least 50% gluten degradation compared to placebo in the duodenum, was achieved in 10 of 13 comparisons. In the stomach, gluten levels were reduced from 176.9 (median, interquartile range 73.5-357.8) to 22.0 (10.6-50.8, p = 0.001) in the high dose and to 25.4 μg × min/ml (16.4-43.7, p = 0.001) in the low dose. In the duodenum, gluten levels were reduced from 14.1 (8.3-124.7) in the placebo to 6.3 (3.5-19.8, p = 0.019) in the high dose and to 7.4 μg × min/ml in the low dose (3.8-12.0, p = 0.015). Thus even in a physiological meal setting, AN-PEP significantly degraded most gluten in the stomach before it entered the duodenum.

    Endoscopic retrograde cholangiopancreatography (ERCP) requires deep biliary cannulation. When deep biliary cannulation is failed, the endoscopic ultrasonography rendezvous technique (EUS-RV) is a useful salvage method. From the previous 15 articles that included 382 EUS-RV cases, the overall success rate of EUS-RV is 81 % with a complication rate of 10 %. In EUS-RV, the bile duct is punctured under EUS guidance and a guidewire is advanced into the duodenum via the papilla. The EUS scope is then switched to a duodenoscope and inserted into the bile duct over the guidewire exiting the papilla, or the guidewire is grasped with forceps and passed through the working channel; the catheter can then be inserted through the papilla over the wire. There are three puncture routes for EUS-RV: transgastric puncture of the intrahepatic bile duct (IHBD), transduodenal puncture of the extrahepatic bile duct (EHBD) via the proximal duodenum (D1), and transduodenal puncture of the EHBD via the second portion of the duodenum (D2). The puncture route for each patient should be selected based on the patient condition. GW selection for EUS-RV is critical, a hydrophilic GW is useful for this procedure. Although EUS-RV is now performed relatively routinely in a few high-volume centers, procedure standardization and the development of exclusive devices for EUS-RV are still underway. The development of exclusive devices for EUS-RV and prospective comparative studies with other salvage methods are needed to truly evaluate the procedure's usefulness and safety.

    Uroguanylin (UGN) is a 16 amino acid peptide produced mainly by intestinal epithelial cells. Nutrients intake increases circulating levels of prouroguanylin that is processed and converted to UGN to activate the guanylyl cyclase 2C receptor (GUCY2C). Given that the UGN-GUCY2C system has been proposed as a novel gut-brain endocrine axis regulating energy balance, the aim of the present study was to investigate the regulation of UGN protein levels in duodenum and circulating levels in lean and obese mice under different nutritional conditions and its potential interaction with leptin. Swiss, C57BL/6 wild-type and ob/ob male adult mice under different nutritional conditions were used: fed ad libitum standard diet (control); 48 h fasting (fasted); 48 h fasting followed by 24 h of feeding (refed); and fed high-fat diet (45 %) during 10 weeks. In addition, peripheral leptin administration was performed. Intestinal uroguanylin expression was studied by Western blot analysis; plasma levels were measured by ELISA. Food deprivation significantly reduced plasma UGN levels, which were correlated with the lower protein levels of UGN in duodenum. These effects were reverted after refeeding and leptin challenge. Consistently, in ob/ob mice UGN expression was decreased, whereas leptin treatment up-regulated UGN levels in duodenum in these genetically modified mice compared to WT. Diet-induced obese mice displayed increased UGN levels in intestine and plasma in comparison with lean mice. Our findings suggest that UGN levels are correlated with energy balance status and that the regulation of UGN by nutritional status is leptin-dependent.

    Full Text Available Abstract Background Familial adenomatous polyposis (FAP is a hereditary disorder characterized by polyposis along the gastrointestinal tract. Information on adenoma status below the duodenum has previously been restricted due to its inaccessibility in vivo. Capsule Endoscopy (CE may provide a useful adjunct in screening for polyposis in the small bowel in FAP patients. This study aims to evaluate the effectiveness of CE in the assessment of patients with FAP, compared to other imaging modalities for the detection of small bowel polyps. Method 20 consecutive patients with previously diagnosed FAP and duodenal polyps, presenting for routine surveillance of polyps at The Royal Melbourne Hospital were recruited. Each fasted patient initially underwent a magnetic resonance image (MRI of the abdomen, and a barium small bowel follow-through study. Capsule Endoscopy was performed four weeks later on the fasted patient. An upper gastrointestinal side-viewing endoscopy was done one (1 to two (2 weeks after this. Endoscopists and investigators were blinded to results of other investigations and patient history. Results Within the stomach, upper gastrointestinal endoscopy found more polyps than other forms of imaging. SBFT and MRI generally performed poorly, identifying fewer polyps than both upper gastrointestinal and capsule endoscopy. CE was the only form of imaging that identified polyps in all segments of the small bowel as well as the only form of imaging able to provide multiple findings outside the stomach/duodenum. Conclusion CE provides important information on possible polyp development distal to the duodenum, which may lead to surgical intervention. The place of CE as an adjunct in surveillance of FAP for a specific subset needs consideration and confirmation in replication studies.

    Purpose: The purpose of this study was to evaluate the variability in target volume and organ at risk (OAR) contour delineation for retroperitoneal sarcoma (RPS) among 12 sarcoma radiation oncologists. Methods and Materials: Radiation planning computed tomography (CT) scans for 2 cases of RPS were distributed among 12 sarcoma radiation oncologists with instructions for contouring gross tumor volume (GTV), clinical target volume (CTV), high-risk CTV (HR CTV: area judged to be at high risk of resulting in positive margins after resection), and OARs: bowel bag, small bowel, colon, stomach, and duodenum. Analysis of contour agreement was performed using the simultaneous truth and performance level estimation (STAPLE) algorithm and kappa statistics. Results: Ten radiation oncologists contoured both RPS cases, 1 contoured only RPS1, and 1 contoured only RPS2 such that each case was contoured by 11 radiation oncologists. The first case (RPS 1) was a patient with a de-differentiated (DD) liposarcoma (LPS) with a predominant well-differentiated (WD) component, and the second case (RPS 2) was a patient with DD LPS made up almost entirely of a DD component. Contouring agreement for GTV and CTV contours was high. However, the agreement for HR CTVs was only moderate. For OARs, agreement for stomach, bowel bag, small bowel, and colon was high, but agreement for duodenum (distorted by tumor in one of these cases) was fair to moderate. Conclusions: For preoperative treatment of RPS, sarcoma radiation oncologists contoured GTV, CTV, and most OARs with a high level of agreement. HR CTV contours were more variable. Further clarification of this volume with the help of sarcoma surgical oncologists is necessary to reach consensus. More attention to delineation of the duodenum is also needed.

    Paraduodenal pancreatitis (PP) is a unique form of focal chronic pancreatitis that selectively involves the duodenum and aberrant pancreatic tissue located near the minor papilla (beyond the pancreas proper). The pseudotumoral nature of the disease often generates considerable clinical quandary and patient apprehension, and therefore merits a better understanding. The present study appraises the clinicoradiological manifestations of PP in 33 patients. Clinical, laboratory, and radiological manifestations of 33 patients of PP treated in gastroenterology/hepatology and hepato-pancreatico-biliary surgery units during June 2010-August 2014 were retrospectively reviewed. All patients were young to middle-aged men (100%) with history of alcohol abuse (93.9%) and/or smoking (42.4%), who presented either with acute or gradually worsening abdominal pain (90.9%). Pancreatic enzymes and serum tumor markers remained normal or were mildly/transiently elevated. Cystic variant was detected in 57.6% (solid in 42.4%); the disease remained confined to the groove/duodenum (pure form) in 45.4%. Medial duodenal wall thickening with increased enhancement was seen in 87.87 and 81.81%, respectively, and duodenal/paraduodenal cysts were seen in 78.78%. Pancreatic calcifications and biliary stricture were seen 27.3% patients. Peripancreatic arteries were neither infiltrated nor encased. PP has a discrete predilection for middle-aged men with history of longstanding alcohol abuse and/or smoking. Distinguishing imaging findings include thickening of the pancreatic side of duodenum exhibiting increased enhancement with intramural/paraduodenal cysts. This may be accompanied by plate-like scar tissue in the groove region, which may simulate groove pancreatic carcinoma. However, as opposed to carcinoma, the peripancreatic arteries are neither infiltrated nor encased, rather are medially displaced

    Parenteral nutrition (PN) has been found to influence duodenal motility in animals. Choline is an essential nutrient, and its deficiency is related to PN-associated organ diseases. Therefore, this study was aimed to investigate the role of choline supplementation in an infant rat model of PN-associated duodenal motility disorder. Three-week-old Sprague-Dawley male rats were fed chow and water (controls), PN solution (PN), or PN plus intravenous choline (600 mg/kg) (PN + choline). Rats underwent jugular vein cannulation for infusion of PN solution or 0.9% saline (controls) for 7 days. Duodenal oxidative stress status, concentrations of plasma choline, phosphocholine, and betaine and serum tumor necrosis factor (TNF)-α were assayed. The messenger RNA (mRNA) and protein expression of c-Kit proto-oncogene protein (c-Kit) and membrane-bound stem cell factor (mSCF) together with the electrophysiological features of slow waves in the duodenum were also evaluated. Rats on PN showed increased reactive oxygen species; decreased total antioxidant capacity in the duodenum; reduced plasma choline, phosphocholine, and betaine; and enhanced serum TNF-α concentrations, which were reversed by choline intervention. In addition, PN reduced mRNA and protein expression of mSCF and c-Kit, which were inversed under choline administration. Moreover, choline attenuated depolarized resting membrane potential and declined the frequency and amplitude of slow waves in duodenal smooth muscles of infant rats induced by PN, respectively. The addition of choline to PN may alleviate the progression of duodenal motor disorder through protecting smooth muscle cells from injury, promoting mSCF/c-Kit signaling, and attenuating impairment of interstitial cells of Cajal in the duodenum during PN feeding. © 2015 American Society for Parenteral and Enteral Nutrition.

    Intestinal Mϕ play a pivotal role in the maintenance of gut homeostasis, but can also contribute to inflammation such as inflammatory bowel disease (IBD). In contrast to human tissues, little is known about phenotypes of Mϕ in the canine gastrointestinal tract. Therefore, an immunohistochemical study was performed using Abs against Mϕ-associated molecules (Cluster of differentiation (CD)64, CD163, CD204, ionized calcium-binding adaptor molecule 1, L1 Ag, and MHC II) on stomach, duodenum, jejunum, ileum and colon from non-IBD dogs. In addition, marker-expression in the stomach, duodenum and colon of the non-IBD dogs was compared to that in dogs with IBD. Results revealed predominance of resident Mϕ displaying an anti-inflammatory phenotype represented by expression of CD163 as well as CD204 in the gut of non-IBD dogs with high Mϕ numbers especially present in the small intestinal villus area. Compared to non-IBD tissue counterparts, stomach, duodenum, and colon from dogs with IBD showed reduced Mϕ numbers with the exception of slightly increased numbers of CD64+ Mϕ. Correlation analyses between marker-expression of Mϕ and the Canine Inflammatory Bowel Disease Activity Index as well as histological scores failed to reveal relevant relationships. The present study provides evidence of the canine steady state gastrointestinal tract being dominated by Mϕ with anti-inflammatory properties maintaining gut homeostasis. A significant reduction in these resident Mϕ may reflect disturbances in homeostatic capacity that could contribute to the development of canine IBD. In contrast to human IBD and murine disease models, infiltration of pro-inflammatory Mϕ does not significantly contribute to the inflammatory process of canine IBD, which may illustrate possible species-specific differences in IBD pathogenesis.

    Full Text Available The functional development of the small intestine was investigated in Japanese quail chicks subjected to simulated microgravity (hypodynamy on the second day after hatching and reared under these conditions to 63 days of age. On days 5, 7, 14, 21, 28, 35, 42, 56 and 63 the activity of brush-border-bound alkaline phosphatase (AP in the duodenum and jejunum were determined in experimental animals as well as in control quail chicks housed in a floor box during these periods. As compared with control quails the experimental animals displayed a significantly increased enzyme activity until day 42 in the duodenum and day 35 in the jejunum (P < 0.001 whereas in older quails no significant enzymatic differences between these groups was found. However, a decrease in food consumption due to a partial physical constraint cannot be excluded. Moreover, the results suggested that the activity of AP in the control birds did not change substantially during all the periods examined. In contrast, in older hypodynamy quail the AP activity significantly decreased in the duodenum on days 56 and 63 and in the jejunum on days 42, 56 and 63, respectively. These results indicate that a the enhanced intestinal function in early periods of life may reflect the higher sensitivity of small intestine to simulated weightlessness, b the decrease of the AP activity in older animals to the level of controls might be considered as a part of intestinal mechanisms involved in adaptation of quail chicks to long-term hypodynamy, c different activity of AP in the small intestine of Japanese quail may not have resulted only from hypodynamy but also due to decreased food intake.

  12. The ethanol-induced stimulation of rat duodenal mucosal bicarbonate secretion in vivo is critically dependent on luminal Cl-.

    Directory of Open Access Journals (Sweden)

    Anna Sommansson

    Full Text Available Alcohol may induce metabolic and functional changes in gastrointestinal epithelial cells, contributing to impaired mucosal barrier function. Duodenal mucosal bicarbonate secretion (DBS is a primary epithelial defense against gastric acid and also has an important function in maintaining the homeostasis of the juxtamucosal microenvironment. The aim in this study was to investigate the effects of the luminal perfusion of moderate concentrations of ethanol in vivo on epithelial DBS, fluid secretion and paracellular permeability. Under thiobarbiturate anesthesia, a ∼30-mm segment of the proximal duodenum with an intact blood supply was perfused in situ in rats. The effects on DBS, duodenal transepithelial net fluid flux and the blood-to-lumen clearance of 51Cr-EDTA were investigated. Perfusing the duodenum with isotonic solutions of 10% or 15% ethanol-by-volume for 30 min increased DBS in a concentration-dependent manner, while the net fluid flux did not change. Pre-treatment with the CFTR inhibitor CFTRinh172 (i.p. or i.v. did not change the secretory response to ethanol, while removing Cl- from the luminal perfusate abolished the ethanol-induced increase in DBS. The administration of hexamethonium (i.v. but not capsazepine significantly reduced the basal net fluid flux and the ethanol-induced increase in DBS. Perfusing the duodenum with a combination of 1.0 mM HCl and 15% ethanol induced significantly greater increases in DBS than 15% ethanol or 1.0 mM HCl alone but did not influence fluid flux. Our data demonstrate that ethanol induces increases in DBS through a mechanism that is critically dependent on luminal Cl- and partly dependent on enteric neural pathways involving nicotinic receptors. Ethanol and HCl appears to stimulate DBS via the activation of different bicarbonate transporting mechanisms.

    Full Text Available The study was performed with the objective of verifying raw soy feed, oxidized oil feed, and a control group. Performance evaluation was done at 7, 14, and 21 days of age. Metabolism assay was carried out between the 17th and 20th days for nutrient digestibility analysis. On the 21st day, two birds per repetition were sent for necropsy and collection of intestine fragments (duodenum and jejunum for histomorphometric analysis. Eight to 14 days after treatment with Salmonella, individuals showed lower feed intake and feed conversion than the control group. Treatment with coccidiosis decreased all performance parameters in the control. Raw soybeans and oxidized oil induce lower weight gain and higher feed conversion compared to the control feed. Unlike after 14 days, at 21 days treatment with salmonella a decrease in weight gain was noted. For the group challenged by coccidiosis feed intake, the feed conversion remained lower than the control group. Undesirable effects on performance in the groups fed raw soybean and oxidized oil remained at up to 21 days. In the evaluation of digestibility, it was observed that raw soy had lower values for digestibility of dry matter, ether extract, and nitrogen balance due to intake. In addition, a lower ratio of villus:crypt measurements was observed. Lower villus height was found in the duodenum of the group challenged by coccidiosis. This group presented a positive correlation between the digestibility of ether extract and the duodenum, indicating that increased villus height implies an increased digestibility of ether extract. The results obtained for the jejunum showed a positive correlation with villus height in groups challenged by coccidiosis, raw soybeans, and oxidized oil; and to crypt depth in the group challenged with oxidized oil. The information obtained in the present study demonstrates that nutrient digestibility parameters can be useful tools for the analysis of the intestinal health of broiler

    Purpose: The aim of this work was to determine predictive factors for gastroduodenal (GD) toxicity in hepatocellular carcinoma (HCC) patients who were treated with radiotherapy (RT). Patients and methods: A total of 90 HCC patients who underwent esophagogastroduodenoscopy (EGD) before and after RT were enrolled. RT was delivered as 30-50 Gy (median 37.5 Gy) in 2-5 Gy (median 3.5 Gy) per fraction. All endoscopic findings were reviewed and GD toxicities related to RT were graded by the Common Toxicity Criteria for Adverse Events, version 3.0. The predictive factors for the {>=} grade 2 GD toxicity were investigated. Results: Endoscopic findings showed erosive gastritis in 14 patients (16 %), gastric ulcers in 8 patients (9 %), erosive duodenitis in 15 patients (17 %), and duodenal ulcers in 14 patients (16 %). Grade 2 toxicity developed in 19 patients (21 %) and grade 3 toxicity developed in 8 patients (9 %). V{sub 25} for stomach and V{sub 35} for duodenum (volume receiving a RT dose of more than x Gy) were the most predictive factors for {>=} grade 2 toxicity. The gastric toxicity rate at 6 months was 2.9 % for V{sub 25} {<=} 6.3 % and 57.1 % for V{sub 25} > 6.3 %. The duodenal toxicity rate at 6 months was 9.4 % for V{sub 35} > 5.4 % and 45.9 % for V{sub 35} > 5.4 %. By multivariate analysis including the clinical factors, V{sub 25} for stomach and V{sub 35} for duodenum were the significant factors. Conclusion: EGD revealed that GD toxicity is common following RT for HCC. V{sub 25} for the stomach and V{sub 35} for the duodenum were the significant factors to predict {>=} grade 2 GD toxicity.

    Gastrointestinal toxicity of nonsteroidal antiinflammatory drugs includes perforations and bleeds. Several preventive strategies are being tested for cost-effectiveness, but little is known about the costs of the complications they are trying to prevent. We estimated the direct costs of hospital treatment of bleeding and perforated ulcers in a university hospital, from data in discharge letters and the hospital management information system. Eligible patients had been treated in the VU University Medical Center between January 1997 and August 2000 for an ulcer bleed or perforation (International Classification of Diseases code 531-4). Resource use comprised hospitalization days and diagnostic and therapeutic interventions. Insurance claim prices determined the costs from the payers' perspective. In a secondary analysis we excluded resource use that was clearly related to the treatment of comorbid illness. Fifty-three patients with a bleeding (n = 35) or perforated ulcer (n = 15) or both (n = 3) were studied, including 14 with comorbidity; 22 complications occurred in the stomach, 29 in the duodenum, one in both stomach and duodenum, and one after partial gastrectomy. A simultaneous bleed and perforation was most expensive (26,000 euro), followed by perforation (19,000 euro) and bleeding (12,000 euro). A bleed in the duodenum was more expensive than in the stomach (13,000 euro vs 10,000 euro), while the opposite was seen for perforations (13,000 euro vs 21,000 euro). Comorbidity increased costs substantially: even after correction for procedures unrelated to the ulcer complication, comorbidity more than doubled the costs of treatment. Treatment of complicated ulcers is expensive, especially in patients with comorbid conditions.

    The aim of this study was to evaluate the use of a commercially available blueberry juice (BJ) both as a positive and negative oral contrast agent and to present the exact contents of paramagnetic ions. The concentration of Mn and Fe were determined in tinned myrtilles in syrup (atomic absorption). Nine healthy volunteers and 12 patients (age range 20-65 years) were examined using a 1-T MR scanner before and after per os administration of 430 ml of BJ. A qualitative analysis of signal alterations in the stomach, duodenum, and proximal small intestine was performed. In addition, a quantitative analysis was assessed in terms of signal-to-noise ratio calculation. The mean concentration (x {+-} SD) of the ions found in the content of the three cans were 3.3 {+-} 0.4 {mu}g/g for iron and 20.6 {+-} 2.6 {mu}g/g for manganese. Based on the qualitative evaluation, signal alteration on T1-weighted images after administration of BJ was statistically significant in the stomach and duodenum, but not in the proximal small bowel. Signal alteration on T2-weighted images was not statistically significant in any part of the gastrointestinal tract. The quantitative analysis of the T1- and T2 shortening showed that BJ is efficient with only T1-weighted sequences, and this applied to the stomach, duodenum, and proximal small bowel. Blueberry juice can be used as an oral contrast agent in upper abdominal MR for T1-weighted imaging. (orig.)

Based on the qualitative evaluation, signal alteration on T1-weighted images after administration of BJ was statistically significant in the stomach and duodenum, but not in the proximal small bowel. Signal alteration on T2-weighted images was not statistically significant in any part of the gastrointestinal tract. The quantitative analysis of the T1- and T2 shortening showed that BJ is efficient with only T1-weighted sequences, and this applied to the stomach, duodenum, and proximal small bowel. Blueberry juice can be used as an oral contrast agent in upper abdominal MR for T1-weighted imaging. (orig.)

    Nineteen baboons aged 1 to 310 days were given oral doses of 238 Pu citrate or 239 Np nitrate. Gastrointestinal (GI) absorption of Pu and Np were higher than those observed in adults. The values of Pu GI absorption were 0.22% at 1 d, 0.17% at 17 d then about 0.10% until 177 d of age. From 195 d onwards, GI absorption was about 0.02% vs adult values (0.008%). GI absorption of neptunium decreased rapidly with age from 1.71% at 4 d to 0.14% at 6 d and remained at this value until 26 d. From 77 d onwards Np GI absorption was decreased to adult value (0.042%). Gastrointestinal retention associated with GI absorption was small, below 0.4% for Pu and 0.2% for Np. Np and Pu was mainly retained in the small intestine. Pu was retained in the ileum wall till 66 d, and afterwards in the duodenum wall. Histological study of Pu retention showed that it was confined to the macrophages under the ileum villi epithelial cells. Np did not seem to have a well-defined retention compartment. Retention occurred first in the ileum wall up to 6 d, afterwards it was divided between the ileum and duodenum walls up to 77 d and finally, between the duodenum and jejunum walls from 132 days of age onwards. The study shows a difference between Np and Pu GI absorption in neonatal baboons. Np GI absorption decreased to adult value in less than 3 months whereas Pu GI absorption decreased to adult value within 195 days. Our Pu results demonstrated that, the tenfold increase of actinides gastrointestinal transfer proposed by ICRP up to 12 months of age in newborn humans seems acceptable. (authors) [fr

    Dynamic MR cholangiography was conducted on patients with cholelithiasis or choledocholithiasis who had consumed a fatty test meal (Molyork) and the cystic contractility and dynamics of biliary stasis was evaluated. The subjects were 25 with intracystic cholelithiasis, 10 with choledocholithiasis and 10 normal controls. For an imaging sequence, the rapid acquisition with relaxation enhancement (RARE) method was employed and imaging was conducted for 40 min (every 30 s following Molyork administration) without breath-holding. The gallbladder contraction ratio was computed and the contractile ratio for the common bile duct was calculated. To determine the bile flow to the duodenum, the high-intensity signal, indicating the flow from the lower common bile duct, and perfusion of the duodenum were observed in dynamic mode on the monitor with the naked eye and interpreted as positive bile flow. The frequency of this flow was visually monitored. The gallbladder contractile ratio was significantly reduced in patients with cholelithiasis or choledocholithiasis compared with the controls. In a comparison with the normal controls, no sequential changes were noted in the mean contractile ratio of the common bile duct of the patients with cholelithiasis or choledocholithiasis. The mean frequency of bile flow observed for each 40 min period was 13±2.4, 6±2.2, and 4±1.3 times for the controls, those with intracystic cholelithiasis, and those with choledocholithiasis, respectively. Compared with the controls, the latter two patient groups showed evident reductions in the frequency of bile flow to the duodenum (p<0.001). Dynamic MRC combined with Molyork loading makes it possible to compute cystic contractile ratios and perform a dynamic examination of bile flow under non-invasive, near-physiological conditions.

    The purpose of the present study was to illustrate the modality of rotation of ventral and dorsal pancreatic buds by three-dimensional (3D) reconstructions in the rat embryos, during the Carnegie stages 13-17. Serial sections of thirty rat embryos stages 13-17, were observed. The embryos were fixed in Bouin's solution, dehydrated, and paraffin embedded. The sections, 7 μm thick, were cut in longitudinal or transverse planes and were stained alternately by hematoxylin-eosin or Heindenhain' azan. The images were digitalized by Canon Camera 350 EOS D. The 3D reconstruction was performed by computer using Cell Image Analyser software. The two pancreatic buds ventral and dorsal, were clearly identified at stage 13, in anterior and posterior position, respectively, in relation to the duodenum. In stage 15, the duodenum started its rotation of 90° clockwise. The ventral bud moved 90° from the midline to the right. In stage 16, the ventral pancreas continued its rotation until 180° in posterior position behind the duodenum. In stage 17, the two pancreatic buds were related closely to the ventral part of the portal vein. The two buds began to merge. The anterior face of the pancreas's head was arising from the dorsal pancreatic bud. The rest of the head including the omental tuberosity and the uncinate process emanated from the ventral pancreatic bud. The use of 3D reconstruction of the pancreas of rat embryos illustrates the modality of the two pancreatic buds rotation and fusion. This method explains the final position of the pancreas.

    A 71-year-old man with a positive fecal occult blood test was diagnosed with transverse colon cancer and referred to our hospital. Colonoscopy revealed type II transverse colon cancer with circumferential involvement. Contrast-enhanced computed tomography (CT)revealed a tumor with an unclear boundary in the pancreas. No metastases to the liver or lungs were detected, and there were no significantly enlarged regional lymph nodes. During open surgery, the tumor of the transverse colon was found to have formed a mass in the pancreatoduodenum, and it was difficult to separate them. As curative resection was considered possible, resections of both the pancreatoduodenum and transverse colon cancer were performed. Laboratory findings revealed fistula formation between the transverse colon cancer and the duodenum. The cancer was diagnosed as stageII, T4bN0M0, and R0 surgery was successfully performed. The patient was alive without recurrence 14- months after the surgery. Colorectal cancer is more likely to advance locally and directly invade the surrounding organs. However, fistula formation with the duodenum has rarely been reported, occurring at an estimated incidence of 0.1%. Such tumors are typically large; however, metastases rates to the lymph nodes are low. Histopathological examination of the resected specimen revealed a severe inflammatory adhesion, and fistula formation between the traverse colon and the duodenum. There was no evidence of invasion of the lymphatic system or blood vessels, which enabled us to perform a high curative surgery. We propose that it is important to consider high curative resection with positive lymph node dissection for cases of colorectal cancer associated with duodenal fistula formation.

    The objective of this analysis was to examine the intestinal digestibility of individual long-chain fatty acids (FA) in lactating dairy cows. Available data were collated from 15 publications containing 61 treatments, which reported total and individual FA duodenal flows and calculations of intestinal digestibility. All studies involved lactating dairy cows, and estimates of digestibility were based on measurements either between the duodenum and ileum (18 treatments) or between the duodenum and feces (43 treatments). Fatty acid digestibility was calculated for C16:0, C18:0, C18:1 (cis and trans isomers), C18:2, and C18:3. Digestibility of C18:0 was lower than for C18:1 and C18:3, with no difference in digestibility between saturated FA (C16:0 and C18:0). We weighted the studies by the reciprocal of the variance to generate best-fit equations to predict individual FA digestibility based on duodenal flow of FA and dietary independent variables. The flow of C18:0 negatively affected the digestibility of C18:0 and was also included in the best-fit equations for all other 18-carbon FA using duodenal flow characteristics. The type of fat supplemented had an effect on digestibility of individual FA, with whole seeds having reduced digestibility. Our meta-analysis results showed minimal differences in the digestibility of individual FA. However, C18:0 flow through the duodenum had a negative effect on the digestibility of several individual FA, with the largest negative effect on C18:0 digestibility. The mechanisms that reduce C18:0 absorption at high concentrations are unknown and warrant further investigation. Copyright © 2015 American Dairy Science Association. Published by Elsevier Inc.

    Six duodenally and ileally cannulated steers were used in 3 sequential studies to measure 1) basal nutrient flows from a soybean hull-based diet, 2) small intestinal digestibility of raw cornstarch continuously infused into the duodenum, and 3) responses of small intestinal starch digestion to duodenal infusion of 200 or 400 g/d casein. Our objective was to evaluate responses in small intestinal starch digestion in cattle over time and to measure responses in small intestinal starch digestion to increasing amounts of MP. On average, cattle consumed 3.7 kg/d DM, 68 g/d dietary N, and 70 g/d dietary starch. Starch flow to the duodenum was small (38 g/d), and N flow was 91 g/d. Small intestinal digestibility of duodenal N was 57%, and small intestinal digestion of duodenal starch flow was extensive (92%). Small intestinal starch digestibility was 34% when 1.5 kg/d raw cornstarch was continuously infused into the duodenum. Subsequently, cattle were placed in 1 of 2 replicated Latin squares that were balanced for carryover effects to determine response to casein infusions and time required for adaptation. Duodenal infusion of casein linearly increased (P ≤ 0.05) small intestinal starch digestibility, and small intestinal starch digestion adapted to infusion of casein in 6 d. Ethanol-soluble starch and unpolymerized glucose flowing to the ileum increased linearly (P ≤ 0.05) with increasing infusion of casein. Plasma cholecystokinin was not affected by casein infusion, but circulating levels of glucose were increased by casein supplementation (P ≤ 0.05). Responses in small intestinal starch digestion in cattle adapted to casein within 6 d, and increases in duodenal supply of casein up to 400 g/d increased small intestinal starch digestion in cattle.

    Despite the improvements of surgical techniques and postoperative management of patients with liver transplantation, biliary complications are one of the most common and important adverse events. We present a first case of choledochoduodenostomy using magnetic compression following a massive resection of the small intestine due to strangulated ileus after living donor liver transplantation. The 54-year-old female patient had end-stage liver disease, secondary to liver cirrhosis, due to primary sclerosing cholangitis with ulcerative colitis. Five years earlier, she had received living donor liver transplantation using a left lobe graft, with resection of the extrahepatic bile duct and Roux-en-Y anastomosis. The patient experienced sudden onset of intense abdominal pain. An emergency surgery was performed, and the diagnosis was confirmed as strangulated ileus due to twisting of the mesentery. Resection of the massive small intestine, including choledochojejunostomy, was performed. Only 70 cm of the small intestine remained. She was transferred to our hospital with an external drainage tube from the biliary cavity and jejunostomy. We initiated total parenteral nutrition, and percutaneous transhepatic biliary drainage was established to treat the cholangitis. Computed tomography revealed that the biliary duct was close to the duodenum; hence, we planned magnetic compression anastomosis of the biliary duct and the duodenum. The daughter magnet was placed in the biliary drainage tube, and the parent magnet was positioned in the bulbus duodeni using a fiberscope. Anastomosis between the left hepatic duct and the duodenum was accomplished after 25 days, and the biliary drainage stent was placed over the anastomosis to prevent re-stenosis. Contributions to the successful withdrawal of parenteral nutrition were closure of the ileostomy in the adaptive period, preservation of the ileocecal valve, internal drainage of bile, and side-to-side anastomosis

  5. Paracetamol as a Post Prandial Marker for Gastric Emptying, A Food-Drug Interaction on Absorption.

    Directory of Open Access Journals (Sweden)

    R Bartholomé

    Full Text Available The use of paracetamol as tool to determine gastric emptying was evaluated in a cross over study. Twelve healthy volunteers were included and each of them consumed two low and two high caloric meals. Paracetamol was mixed with a liquid meal and administered by a nasogastric feeding tube. The post prandial paracetamol plasma concentration time curve in all participants and the paracetamol concentration in the stomach content in six participants were determined. It was found that after paracetamol has left the stomach, based on analysis of the stomach content, there was still a substantial rise in the plasma paracetamol concentration time curve. Moreover, the difference in gastric emptying between high and low caloric meals was missed using the plasma paracetamol concentration time curve. The latter curves indicate that (i part of the paracetamol may leave the stomach much quicker than the meal and (ii part of the paracetamol may be relatively slowly absorbed in the duodenum. This can be explained by the partition of the homogenous paracetamol-meal mixture in the stomach in an aqueous phase and a solid bolus. The aqueous phase leaves the stomach quickly and the paracetamol in this phase is quickly absorbed in the duodenum, giving rise to the relatively steep increase of the paracetamol concentration in the plasma. The bolus leaves the stomach relatively slowly, and encapsulation by the bolus results in relatively slow uptake of paracetamol from the bolus in the duodenum. These findings implicate that paracetamol is not an accurate post prandial marker for gastric emptying. The paracetamol concentration time curve rather illustrates the food-drug interaction on absorption, which is not only governed by gastric emptying.ClinicalTrials.gov NCT01335503 Nederlands Trial Register NTR2780.

    Colitis is associated with functional abnormalities in proximal non-inflamed gut areas, but animal models to study small bowel dysfunction in colitis have limitations. This study aims to determine small intestinal alanine absorption and cytokine expression in a novel model of colonic ulceration induced by electro-cautery. A descending colon ulcer was induced in rats by a bipolar electro-cautery probe. Ulcer score was determined using Satoh's criteria. Jejunal alanine absorption was measured immediately and at different time intervals post ulcer induction. Levels of interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) protein and m-RNA were determined in mucosal scrapings obtained from the colon, duodenum, jejunum and ileum at various time intervals after colonic ulcer induction. The mean ulcer score was 3 up to 48h, followed by healing by 96h post ulcer induction. Small bowel histology was normal throughout. Jejunal alanine absorption was reduced by 12-34% immediately and up to 72h after cautery and returned to normal at 96h. IL-1 and TNF-α mRNA increased significantly in the colon, duodenum, jejunum and ileum 3h post electro-cautery and returned to normal at 48h, while that of IL-6 increased significantly at 48h post ulcer induction. Similarly, IL-1, IL-6 and TNF-α protein levels increased in the duodenum, jejunum, ileum and colon up to 48h post ulcer induction. Electrically induced localized colonic injury increased production of pro-inflammatory cytokines in non-inflamed segments of the small intestine and was associated with derangements of jejunal absorptive function.

    Full Text Available Human immunodeficiency virus type 1 (HIV-1 infects and destroys cells of the immune system leading to an overt immune deficiency known as HIV acquired immunodeficiency syndrome (HIV/AIDS. The gut associated lymphoid tissue is one of the major lymphoid tissues targeted by HIV-1, and is considered a reservoir for HIV-1 replication and of major importance in CD4+ T-cell depletion. In addition to immunodeficiency, HIV-1 infection also directly causes gastrointestinal (GI dysfunction, also known as HIV enteropathy. This enteropathy can manifest itself as many pathological changes in the GI tract. The objective of this study was to determine the association of gut HIV-1 infection markers with long-term survival in a cohort of men who have sex with men (MSM enrolled pre-HAART (Highly Active Antiretroviral Therapy. We examined survival over 15-years in a cohort of 42 HIV-infected cases: In addition to CD4+ T cell counts and HIV-1 plasma viral load, multiple gut compartment (duodenum and colon biopsies were taken by endoscopy every 6 months during the initial 3-year period. HIV-1 was cultured from tissues and phenotyped and viral loads in the gut tissues were determined. Moreover, the tissues were subjected to an extensive assessment of enteroendocrine cell distribution and pathology. The collected data was used for survival analyses, which showed that patients with higher gut tissue viral load levels had a significantly worse survival prognosis. Moreover, lower numbers of serotonin (duodenum and somatostatin (duodenum and colon immunoreactive cell counts in the gut tissues of patients was associated with significant lower survival prognosis. Our study, suggested that HIV-1 pathogenesis and survival prognosis is associated with altered enteroendocrine cell numbers, which could point to a potential role for enteroendocrine function in HIV infection and pathogenesis.

    The present study evaluated the effects of Saccharomyces boulardii on duodenal digestive enzymes, morphology and cytokine induction response in broiler chicken. A total of 200 birds were allotted into two groups (n = 100) and each group divided into five replications (n = 20). The control group was fed basal diet in addition to antibiotic (virginiamycin 20 mg/kg), and treatment group received (1 × 10 8  colony-forming units/kg feed) S. boulardii in addition to basal diet lasting for 72 days. The results compared to control group revealed that adenosine triphosphatase, gamma glutamyl transpeptidase, lipase and trypsin activities were higher, while, no significant improvement was observed in amylase activities in the duodenum of the treatment group. Moreover, morphological findings showed that villus height, width and number of goblet cells markedly increased. Additionally, transmission electron microscopy visualized that villus height, width and structural condensation significantly increased in the treatment group. The immunohistological observations showed increased numbers of immunoglobulin A (IgA)-positive cells in the duodenum of the treatment group. Meanwhile, cytokine production levels of tumor necrosis factor-α, interleukin (IL)-10, transforming growth factor-β and secretory IgA markedly increased, and IL-6 statistically remained unchanged as compared to the control group. These findings illustrated that initial contact of S. boulardii to the duodenum has significant impact in improving enzymatic activity, intestinal morphology and cytokine response in broiler chicken. © 2016 Japanese Society of Animal Science.

    We searched the effect of the muscular valve on the management of short bowel syndrome. The motility of the remnant intestine with a special muscular valve after 80% massive distal small bowel resection (MSBR) was evaluated in conscious dogs. The valve (muscular ring) was made by the autointestinal muscle layer holding vascular pedicle. Interdigestive and postprandial bowel motility using bipolar electrodes and/or contractile strain gauge force transducers 2-4 weeks after the surgery, and data of this group (Group I) were compared to the motility in dogs after MSBR without valve construction (Group II) and in controls (Control). Results; Fasting duodenal migrating myoelectric (or motor) complexes (MMCs) in Group I occurred at longer intervals than in Control and almost similarly to those in Group II. MMCs arising from the duodenum were often interrupted before the jejunum above the valve and the anastomosis. The velocity of duodenal MMC propagation was slowed in every intestinal segment including that from the duodenum to the proximal jejunum, and to the jejunum above the anastomosis. Transit time in MSBR group (I and II) from the duodenum to the terminal ileum was extremely shorter than in Control, but there were no differences between in Groups I and II. The duration of the postprandial period without duodenal MMCs in Group I was significantly prolonged than in Control, but was shorter than that in Group II. The muscular valve was frequently activated, and the jejunum covered with the valve was contracted frequently which synchronized with the valve activity. It seemed the valve worked as sphincter. However, intestinal obstruction was not occurred through the jejunum covered by the valve. In conclusion, changes in gut motility after MSBR with the valve construction compensate for the shortened intestine and maintain the bowel content earlier postoperatively in comparison with the MSBR alone, and also contribute to the adaptive increase in the remnant intestinal

    Purpose: The purpose of this study was to evaluate the variability in target volume and organ at risk (OAR) contour delineation for retroperitoneal sarcoma (RPS) among 12 sarcoma radiation oncologists. Methods and Materials: Radiation planning computed tomography (CT) scans for 2 cases of RPS were distributed among 12 sarcoma radiation oncologists with instructions for contouring gross tumor volume (GTV), clinical target volume (CTV), high-risk CTV (HR CTV: area judged to be at high risk of resulting in positive margins after resection), and OARs: bowel bag, small bowel, colon, stomach, and duodenum. Analysis of contour agreement was performed using the simultaneous truth and performance level estimation (STAPLE) algorithm and kappa statistics. Results: Ten radiation oncologists contoured both RPS cases, 1 contoured only RPS1, and 1 contoured only RPS2 such that each case was contoured by 11 radiation oncologists. The first case (RPS 1) was a patient with a de-differentiated (DD) liposarcoma (LPS) with a predominant well-differentiated (WD) component, and the second case (RPS 2) was a patient with DD LPS made up almost entirely of a DD component. Contouring agreement for GTV and CTV contours was high. However, the agreement for HR CTVs was only moderate. For OARs, agreement for stomach, bowel bag, small bowel, and colon was high, but agreement for duodenum (distorted by tumor in one of these cases) was fair to moderate. Conclusions: For preoperative treatment of RPS, sarcoma radiation oncologists contoured GTV, CTV, and most OARs with a high level of agreement. HR CTV contours were more variable. Further clarification of this volume with the help of sarcoma surgical oncologists is necessary to reach consensus. More attention to delineation of the duodenum is also needed

    The purpose of this study was to determine whether oral immunization of ferret kits with a whole-cell sonicate of Helicobacter mustelae lysate (Hml) and the adjuvant muramyl dipeptide (MDP) would reduce the incidence of natural colonization with H. mustelae and the extent of Helicobacter-associated gastritis by enhancing the host mucosal immune response. Between the ages of 4 and 11 weeks, 44 ferret kits were gavaged with Hml and various doses of MDP. The extent of gastritis and duodenitis and the immune response to H. mustelae were evaluated. All kits became colonized naturally with H. mustelae and the majority developed mild to severe gastritis and duodenitis. Kits that received Hml with MDP developed significantly greater inflammation of the gastric antrum and duodenum, as compared to kits vaccinated with Hml alone. Vaccination with Hml and 50 micrograms of MDP was associated with severe lesions in the proximal duodenum characterized by accumulation of mononuclear inflammatory cells, mucosal erosion, and ulceration. Although serum antibody specific for H. mustelae in 4-week-old kits was approximately 50% of adult levels, a finding attributable to passively acquired maternal antibody, both systemic and mucosal antibody levels became depressed over time despite oral vaccination. The humoral immune response was sufficiently low to prevent detection of any significant dose effect of MDP on antibody levels among experimental groups. Oral vaccination of young ferrets with Hml and 50 micrograms MDP increased the risk of Helicobacter-associated mucosal ulceration in the proximal duodenum, which was associated with low humoral (but significant cell-mediated) immune responses to H. mustelae. In retrospect, the frequency of vaccination may have suppressed the systemic humoral immune response, thereby promoting mucosal damage by H. mustelae. The 50-microgram dose of MDP enhanced the cell-mediated immune response, which indirectly contributed to development of severe lesions

    Coreopsis tinctoria Nutt mainly distributed in Hetian region of Xinjiang at an altitude of 3000m, which is used as Uyghur traditional medicine because of its clearing heat, promoting circulation and removing toxicity and antihypertension, ect. effect. This research was to study the four ingredients in the extracts of Coreopsis tinctoria Nutt. that are absorbed in different intestinal segments in rats to lay the foundation for further study on the effective constituents, tissue distribution, metabolism, and spectrum-effect relationships of these extracts. High, medium, and low concentrations were prepared according to their pharmacological effects. Quantitative analysis multi-components by single marker was used to test the cumulative absorption volume Q, absorption rate constant Ka, and apparent permeability coefficient Papp of the four main ingredients in C. tinctoria Nutt. extract in different intestinal segments in rats using a Ussing chamber model and high-performance liquid chromatography. The Papp of chlorogenic acid and flavanomarein in the duodenum, jejunum, ileum, and colon were 1.0×10(-6) to 10×10(-6)cms(-1). Papp of marein in the duodenum and jejunum was <1.0×10(-6), and was 1.0×10(-6) to 10×10(-6)cms(-1) in the ileum and colon. Papp of 3,5-O-dicaffeoylquinic acid in the duodenum was <1.0×10(-6)cms(-1), while it was 1.0×(1)0(-6) to 10×10(-6)cms(-1) in the jejunum, ileum, and colon. All four chemical components of the plant extract can be absorbed by the intestinal canal of rats, which conforms to zero-order absorption; the ileum presented the best absorption.

    A seven-year-old, female, domestic short hair cat was presented with a history of chronic anorexia. Radiographic examination revealed a large space-occupying calcified mass in the abdominal cavity. The mass was located in pylorus and did not extend into the duodenum and surrounding tissues. Billroth I gastroduodenostomy was conducted to remove the mass. Histopathological examination of the mass showed a lymphoma. Although Recovery following the operation was excellent, the patient showed intermittent vomiting unrelated to feeding. Radiographical examination revealed a megaesophagus, which was assumed to be a complication of the Billroth I procedure, since the condition was not observed before the procedure

    Pathways and efficiency of NPN utilization were studied after introducing isonitrogenous feeds containing urea labelled with 15 N with or without groundnut protein into the rumen of the young steer. The 15 N abundance in rumen ammonia decreased from 1 h after the dose whereas that in suspended bacteria (only a small part of the total population but regarded, with reservation, as representative) increased to a peak value at 3-5 h. Patterns of incorporation into different nitrogen constituents of the bacteria indicated that part of the 15 N first moved rapidly into a labile pool, which included amide nitrogen, and then moved from this pool into other amino acids. Different amino acids were labelled to different extents (lowest for proline and arginine, highest for aspartic acid and alanine), presumably as different amounts of pre-formed amino acids were used in protein synthesis. Differences largely disappeared when the diet with urea as the only nitrogen source was given. Estimates of microbial 15 N recovery at the duodenum confirmed earlier findings that overall incorporation was least when the latter diet was given, and no improvement was seen when the urea was given in three doses over 4 h instead of in a single dose. Lactosyl, like glucosyl, ureide was degraded fairly slowly in the rumen and is being studied as a possible NPN source likely to yield simultaneous ammonia and energy for microbial growth. Studies on the origin and composition of nitrogen compounds entering the duodenum showed that the RNA of rumen bacteria (labelled with 32 P) contributed 82-109% of the RNA entering the duodenum of the steer. It was also shown that protecting dietary casein with formaldehyde reduced its degradability in the rumen to such an extent that a deficiency of fermentable nitrogen in that organ ensued. In other experiments with two calves receiving flaked maize and hay, net digestibility of nitrogen compounds between duodenum and ileum was about 60%. True digestibility

    Ectopic pancreas is most commonly found in the antrum of the stomach, duodenum, or proximal jejunum. Rarely ectopic pancreas in the proximal stomach has been reported. Moreover, the coexistence of two ectopic pancreases at gastric cardia and antrum in a patient has not been reported. Ectopic pancreas usually appears as a submucosal mass, and it is difficult to differentiate between ectopic pancreas and other common submucosal tumors, such as a gastrointestinal stromal tumor (GIST) or leiomyoma. Here, we present a case of the coexistence of two ectopic pancreases at cardia and antrum of the stomach in a 60-year-old man, which was preoperatively misdiagnosed as GIST

    Familial adenomatous polyposis (FAP) or Gardner’s syndrome is often accompanied by adenomas of the stomach and duodenum. We experienced a case of adenomas of the common bile duct in a 40-year-old woman with FAP presenting with acute cholangitis. Only 8 cases of adenomas or adenocarcinoma of the common bile duct have been reported in the literature in patients with FAP or Gardner’s syndrome. Those patients presented with acute cholangitis or pancreatitis. Local excision or Whipple procedure may be the reasonable surgical option. PMID:25780319

    The rendezvous technique typically involves combined efforts of interventional radiology, endoscopy, and surgery. It can be done solely percutaneously, whereby the interventionalist gains desired access to one point in the body by approaching it from two different access sites. We present the case of a woman who underwent cholecystectomy complicated by a bile duct injury. A percutaneous rendezvous procedure enabled placement of an internal-external drain from the intrahepatic ducts through the biloma and distal common bile duct and into the duodenum. Thus, a percutaneous rendezvous technique is feasible for managing a bile duct injury when endoscopic retrograde cholangio-pancreatography or percutaneous transhepatic cholangiogram alone has been unsuccessful.

    Full Text Available Mesenteric cysts are rarely seen intraabdominal mass lesions which can manifest themselves with different clinical signs, and symptoms. They can locate in the mesenterium from duodenum down to rectum, and also in the retroperitoneal space. Herein we present a very rare case of a scrotal mesenteric cyst which resembled an epididymal cyst in a 6-year-old boy. Ultrasonographic examination revealed a multiloculated cyst completely filling the scrotal sac, and the cyst was excised surgically. Histopathological examination described the surgical specimen as chylolymphatic mesenteric cyst, and during one year follow-up any recurrence was not observed.

    Intraoperative radiotherapy (IOR) of unresected advanced cancers of the biliary system and pancreas improves both subjective and objective symptoms. IOR with radical resection, however, provided excellent local control of the tumor bed and significantly prolonged survival time. The optimal single dose of IOR appears to be 25 to 30 Gy. Bleeding and stenosis of the stomach and duodenum were observed but were prevented by keeping the organs out of the radiotherapy energy field. IOR combined with radical resection is concluded to be an effective method of treating selected cases of cancer of the biliary system and pancreas. (author)

    2014-05-01

    Full Text Available Fasciolopsiasis is a disease caused by the largest food-borne intestinal trematode known as Fasciolopsis buski. Here we report a case of a 50-year-old female who presented with upper abdominal pain and vomiting for one month. She was previously diagnosed as a case of choledocholithiasis. Endoscopic retrograde cholangio-pancreatography (ERCP revealed stones along with two leaf-shaped worms which were removed from the duodenum of the patient. The worms were identified as F. buski by its unique morphology. Awareness regarding this parasitic infestation, especially in the rural area, should gain attention while formulating strategies to prevent and manage such infestation.

    Changes in leukocyte count and in the gut microflora of laboratory rats irradiated with a single whole-body dose of gamma rays (5.0 Gy) were determined. The number of leukocytes was lower especially 1 and 2 weeks after irradiation. A significant decrease in lymphocytes was observed 1 week and in monocytes 1 and 2 weeks after irradiation. In parallel with these changes, an increase in common microflora was observed, some microorganisms, witch normally are not present in duodenum, liver and mouth cavity, were detected in these organs.

    Many compounds affect the bioavailability of radiobiocomplexes as radiopharmaceuticals. Ginkgo Biloba extract (EGb) has several effects. The influence of an EGb on the bioavailability of the radiobiocomplex sodium pertechnetate (Na 99m TcO 4 ) and on the morphometry of the organs was evaluated. Rats were treated with EGb and Na 99m TcO 4 was injected. The animals were sacrificed; the radioactivity in the organs was counted. The results showed that EGb altered the Na 99m TcO 4 bioavailability in the kidneys, liver and duodenum. Morphometric analysis of the organs showed significant alterations (P 99m TcO 4 . (author)

  5. Duodenal diverticula demonstrated by barium examination

    Energy Technology Data Exchange (ETDEWEB)

    Christiansen, T.; Thommesen, P.

    An investigation for biliary tract calculi and food-stimulated gastro-oesophageal reflux was carried out in 37 patients with duodenal diverticula demonstrated by barium examination. Sixty per cent of the diverticula were located in the descending part of the duodenum. Biliary tract calculi were demonstrated in 38 per cent and food-stimulated gastro-oesophageal reflux in 81 per cent of the patients. The detection of a duodenal diverticulum should result in a supplementary investigation for gallstones and gastrooesophageal reflux and its sequelae.

    Full Text Available Trichobezoar is a rare cause of small bowel obstruction, whereby a mass forms most commonly in the stomach and duodenum of young females, from ingestion of hair, a condition known as trichophagia. We present a case of recurrent small bowel obstruction due to a residual hair mass that was removed surgically in a young female patient who had a laparotomy and gastrotomy for removal of a large gastric trichobezoar just two weeks prior to the current admission. This case illustrates the importance of a thorough inspection of the whole bowel to ensure that no residual bezoars remain after surgery.

    Full Text Available The autors report a case of jejunal mucosa prolapse after gastroenteroanastomosis, a rare postoperative complication. In the late postcholecistectomy period the patient had persistent vomit. Upper digestive endoscopy (UDE showed obstruction of the second portion of duodenum, and a gastrojejunal anastomosis was performed. Soon after that, the patient had persistent vomit and upper digestive endoscopy (UDE showed invagination of the jejunal mucosa. She was reoperated, a Roux Y gastrectomy was performed and the patient had a good evolution. The treatment for this complication is basically surgical, which intends to realieve the obstructive symptomatology.

    2013-01-01

    Full Text Available Foreign bodies inside the pancreas are rare and usually occur after the ingestion of sharp objects like fish bone, sewing needle and toothpick. Most of the ingested foreign bodies pass spontaneously through the anus without being noticed but about 1% of them can perforate through the wall of stomach or duodenum to reach solid organs like pancreas or liver. Once inside the pancreas they can produce complications like abscess, pseudoaneurysm or pancreatits. Foreign bodies of pancreas should be removed by endoscopic or surgical methods. We hereby report our experience of successful removal one a sewing needle from pancreas.

    An 88-year-old Japanese woman was admitted to our hospital for abdominal pain with a raised inflammatory reaction. Esophagogastroduodenoscopy (EGD) and computed tomography (CT) showed a duodenal ulcer punching a liver cyst. Since neither ascites nor free air were detected on CT and her family did not wish for aggressive medical treatment, the patient received clinical observation and conservative management. Antibiotic and proton-pump inhibitor therapy was effective, and she exhibited an uneventful recovery. A reexamination of EGD and CT confirmed that the fistulous tract between the liver cyst and duodenum was blockaded.

    2015-03-01

    Avian coccidiosis is a disease caused by the intestinal protozoa Eimeria. The site of invasion and lesions in the intestine is species-specific, for example E. acervulina affects the duodenum, E. maxima the jejunum, and E. tenella the ceca. Lesions in the intestinal mucosa cause reduced feed efficiency and body weight gain. The growth reduction may be due to changes in expression of digestive enzymes and nutrient transporters in the intestine. The objective of this study was to compare the expression of digestive enzymes, nutrient transporters and an antimicrobial peptide in broilers challenged with either E. acervulina, E. maxima or E. tenella. The genes examined included digestive enzymes (APN and SI), peptide and amino acid transporters (PepT1, ASCT1, b(0,+)AT/rBAT, B(0)AT, CAT1, CAT2, EAAT3, LAT1, y(+)LAT1 and y(+)LAT2), sugar transporters (GLUT1, GLUT2, GLUT5 and SGLT1), zinc transporter (ZnT1) and an antimicrobial peptide (LEAP2). Duodenum, jejunum, ileum and ceca were collected 7 days post challenge. E. acervulina challenge resulted in downregulation of various nutrient transporters or LEAP2 in the duodenum and ceca, but not the jejunum or ileum. E. maxima challenge produced both downregulation and upregulation of nutrient transporters and LEAP2 in all three segments of the small intestine and ceca. E. tenella challenge resulted in the downregulation and upregulation of nutrient transporters and LEAP2 in the jejunum, ileum and ceca, but not the duodenum. At the respective target tissue, E. acervulina, E. maxima and E. tenella infection caused common downregulation of APN, b(0,+)AT, rBAT, EAAT3, SI, GLUT2, GLUT5, ZnT1 and LEAP2. The downregulation of nutrient transporters would result in a decrease in the efficiency of protein and polysaccharide digestion and uptake, which may partially explain the weight loss. The downregulation of nutrient transporters may also be a cellular response to reduced expression of the host defense protein LEAP2, which would

    The antiulcer effect of two medicinal forms (oil solution, liniment) of dibunol in rats with different models of the stomach and duodenum ulcers was studied. The therapeutic activity of dibunol was evaluated by determining the index of ulcer formation as well as during the morphological and histochemical studies. The two medicinal forms of dibunol possessed equal antiulcer activity by all studied criteria. One should note a characteristic property of dibunol--its ability to produce pronounced epithelialization of ulceroerosive and ulceronecrotic lesions of the mucosa without rough scarring.

    Sonographic findings of nine cases of intramural hematoma of the gastrointestinal tract are presented. The duodenum was the most common site, followed by the ascending colon and the stomach. Intramural hematomas present as centrally or eccentrically located bowel mass of variable echogenicity: heter-ogeneously echogenic in six cases; hypoechoic in two case; anechoic in one case. In five cases of duodenal hematoma, the stomach and/or duodenal bulb were distended and filled with fluid. It is concluded that ultrasonography is a simple and useful tool in the diagnosis of intramural hematoma of the intestine

    Calves which had received daily infections of Cooperia oncophora over a six week period showed inappetence, weight loss, impaired nitrogen retention and a loss of plasma proteins into the gut. During this period the infections occurred in the duodenum, jejunum and ileum and many larval stages were present in the mucosa of the small intestine. At necropsy, on weeks 3, 6 and 10 after the first infection, stunting and thickening of the villi were noted with excessive mucus production. Prior administration of a morantel slow release bolus prevented these changes. By week 12 most of the worms had been expelled yet a loss of plasma proteins to the gut was still occurring.

    Ectopic pancreas is most commonly found in the antrum of the stomach, duodenum, or proximal jejunum. Rarely ectopic pancreas in the proximal stomach has been reported. Moreover, the coexistence of two ectopic pancreases at gastric cardia and antrum in a patient has not been reported. Ectopic pancreas usually appears as a submucosal mass, and it is difficult to differentiate between ectopic pancreas and other common submucosal tumors, such as a gastrointestinal stromal tumor (GIST) or leiomyoma. Here, we present a case of the coexistence of two ectopic pancreases at cardia and antrum of the stomach in a 60-year-old man, which was preoperatively misdiagnosed as GIST

    A 63-year-old man was found in the street after overrun by a car. Postmortem CT revealed multiple bone fractures, but surprisingly all without any relevant hemorrhage which would have been expected under such circumstances. A round radiopaque formation was found in the duodenum, which was reminiscent of ingested tablets. The toxicological analysis revealed high concentrations of zopiclone and alcohol. By combining radiologic and forensic results, zopiclone and alcohol intoxication were concluded as the cause of death, followed by a postmortem overrun accident.

    1997-01-01

    Full Text Available Gastric outlet obstruction caused by a large gallstone in the duodenum or pylorus (Bouveret's syndrome is a rare complication of gallstone disease. The presenting symptoms are often nonspecific and include nausea, vomiting, epigastric pain and a history of gallbladder disease. Although the diagnosis is established only at surgery in many cases, preoperative recognition by imaging techniques and endoscopy is desirable. Surgical treatment aims at removal of the ectopic gallstone, closure of the fistula and cholecystectomy. A case of Bouveret's syndrome is presented where endoscopic extraction of the duodenal gallstone was accomplished providing definitive treatment for this patient.

    By using a modified technique of double-contrast examination of the stomach it was possible in 75% to perform a study without superposition of the duodenum and jejunum on the distal stomach compared to 36% with the usual method. In this technique a small amount (50 ml) of Barium-suspension is given to the patient in left decubitus position by a straw or gastric tube after antiperistaltic medication. There was no difference in the quality of mucosa-coating compared to the technique using higher volumes of Barium. (orig.) [de

    Equine gastric ulcer syndrome (EGUS) is an umbrella term used to describe ulcers in the nonglandular squamous and glandular mucosa, terminal esophagus, and proximal duodenum. Gastric ulcers in the squamous and glandular regions occur more often than esophageal or duodenal ulcers and likely have a different pathogenesis. At present, omeprazole is accepted globally as the best pharmacologic therapy for both regions of the stomach; however, the addition of coating agents and synthetic prostaglandins could add to its effectiveness in treatment of EGUS. Dietary and environmental management are necessary for prevention of recurrence. Copyright © 2016 Elsevier Inc. All rights reserved.

    In a breeding group of Inca terns (Larosterna inca), 14 birds died without antemortem signs of illness. Other than a poor body condition and a bloody cloaca, no symptoms were observed. Gross necropsy revealed severe segmental hemorrhagic enteritis with intralesional trematodes in most birds. Histopathologic examination revealed infiltration of lymphocytes, plasma cells, and granulocytes in the lamina propria of the duodenum and cross-sections of trematodes in the lumen. The parasites were identified as Ichthyocotylurus erraticus, a trematode of fish-eating birds. The cause of the infestation most likely was the feeding of unfrozen fresh fish. We describe the first case of a lethal I. erraticus infestation in Inca terns.

    Purpose: Evaluate commonly used segmentation algorithms on a commercially available real-time MR image guided radiotherapy (MR-IGRT) system (ViewRay), compare the strengths and weaknesses of each method, with the purpose of improving motion tracking for more accurate radiotherapy. Methods: MR motion images of bladder, kidney, duodenum, and liver tumor were acquired for three patients using a commercial on-board MR imaging system and an imaging protocol used during MR-IGRT. A series of 40 frames were selected for each case to cover at least 3 respiratory cycles. Thresholding, Canny edge detection, fuzzy k-means (FKM), k-harmonic means (KHM), and reaction-diffusion level set evolution (RD-LSE), along with the ViewRay treatment planning and delivery system (TPDS) were included in the comparisons. To evaluate the segmentation results, an expert manual contouring of the organs or tumor from a physician was used as a ground-truth. Metrics value of sensitivity, specificity, Jaccard similarity, and Dice coefficient were computed for comparison. Results: In the segmentation of single image frame, all methods successfully segmented the bladder and kidney, but only FKM, KHM and TPDS were able to segment the liver tumor and the duodenum. For segmenting motion image series, the TPDS method had the highest sensitivity, Jarccard, and Dice coefficients in segmenting bladder and kidney, while FKM and KHM had a slightly higher specificity. A similar pattern was observed when segmenting the liver tumor and the duodenum. The Canny method is not suitable for consistently segmenting motion frames in an automated process, while thresholding and RD-LSE cannot consistently segment a liver tumor and the duodenum. Conclusion: The study compared six different segmentation methods and showed the effectiveness of the ViewRay TPDS algorithm in segmenting motion images during MR-IGRT. Future studies include a selection of conformal segmentation methods based on image/organ-specific information

    Matrix metalloproteinases (MMPs) 2 and 9 are zinc- and calcium-dependent endopeptidases involved in the breakdown and reconstitution of extracellular matrix under both physiological and pathological conditions. Mucosal MMP-2 and -9 activities have been reported to be upregulated in the intestine of humans with inflammatory bowel disease (IBD), and in animal models of IBD. However, their involvement in the pathogenesis of canine chronic enteropathies (CE) is unknown. This study investigated mucosal pro- and active MMP-2 and -9 activities in dogs with CE and healthy dogs using gelatin zymography, and also to determine the association of their activities in dogs with CE with the canine IBD activity index (CIBDAI), histopathologic findings, the clinical outcome, and hypoalbuminemia. Intestinal mucosal samples from duodenum, ileum, colon, and cecum were collected from 40 dogs with CE and 18 healthy Beagle dogs. In dogs with CE, the number of samples positive for mucosal pro- and active MMP-2 was significantly higher in the duodenum (P < 0.0001 and P = 0.011, respectively), ileum (P = 0.002 and P = 0.018, respectively), and colon (P < 0.0001 and P = 0.002, respectively), compared with healthy controls. Mucosal pro-MMP-9-positive samples in the duodenum and colon were significantly more frequent in dogs with CE than in healthy dogs (P = 0.0004 and P = 0.001, respectively). Despite the presence of mucosal samples positive for active MMP-9 in the intestinal segments of dogs with CE, the difference compared to healthy controls did not reach statistical significance. None of the intestinal mucosal samples in healthy dogs showed gelatinolytic activity corresponding to the control bands of active MMP-2 and -9. Mucosal active MMP-9 activities displayed a significant positive association with the severity of neutrophil infiltration in the duodenum (P = 00.040), eosinophils in the cecum (P = 00.037), and the CIBDAI score for ileum samples

    Full Text Available PURPOSE: Interposition of a jejunal tube between the common bile duct and duodenum. METHODS: Five adult mongrel dogs of both sexes, weighing on average 22.3 kg (18 to 26.5 kg, were used. Obstructive jaundice was induced by ligation of the distal common bile duct. After one week, a 2.5-cm long jejunal tube was fabricated from a segment of the loop removed 15 cm from the Treitz angle and interposed between the common bile duct and duodenum. RESULTS: The animals presented good clinical evolution and no complications were observed. After 6 weeks, complete integration was noted between the bile duct mucosa, tube and duodenum and a significant reduction in total bilirubin and alkaline phosphatase was observed when compared to the values obtained one week after ligation of the common bile duct. CONCLUSION: The jejunal tube interposed between the dilated bile duct and duodenum showed good anatomic integration and reduced total bilirubin and alkaline phosphatase levels in the animals studied.OBJETIVO: Interposição de um tubo de jejuno entre o colédoco e o duodeno. MÉTODOS: Foram utilizados cinco cães adultos, sem raça definida, de ambos os sexos, com peso médio de 22,3 Kg (18 e 26,5 Kg. Após provocar icterícia obstrutiva pela ligadura do colédoco distal, após uma semana, praticou-se confecção do tubo de jejuno de 2,5 cm de extensão, que foi realizado com um segmento de alça retirado a 15 cm do ângulo de Treitz e a interposição do tubo entre o colédoco e o duodeno. RESULTADOS: Os animais tiveram boa evolução clínica e não apresentaram complicações. Notou-se total integração entre a mucosa da via biliar, do tubo e do duodeno e redução significativa dos valores da bilirrubina total e da fosfatase alcalina após seis semanas, quando comparado com os valores após uma semana de ligadura do colédoco. CONCLUSÃO: O tubo de jejuno interposto entre a via biliar dilatada e o duodeno, apresentou boa integração anatômica e reduziu os

    Foreign body (FB) ingestion is a common problem in children. Up to 90% of these FBs pass spontaneously. FBs reaching the stomach usually pass out spontaneously. Exceptions to this spontaneous passage include a long FB that cannot cross the pylorus, duodenum or ileocaecal junction. We present a case of a 9-year boy who accidentally ingested a long paper pin, which spontaneously passed in 26 h. This case is being reported to highlight the successful spontaneous passage of a 4 cm long sharp foreign body in a child. 2015 BMJ Publishing Group Ltd.

    2008-01-01

    Full Text Available Jejunal diverticulosis is rare and often goes unnoticed until complications occur. The diverticula are true, acquired diverticula and often asymptomatic. Jejunal diverticulosis can be associated with diverticulosis of the duodenum, ileum, and colon. Here we describe a patient with known severe diverticular disease of the large bowel, who presented acutely with abdominal pain and signs of generalised peritonitis. Laparotomy showed ruptured jejunal diverticulosis with a single band over the terminal ileum, causing small bowel obstruction. Spontaneous perforation of a jejunal diverticulum is rare and is usually an intraoperative finding. One should exclude a precipitating cause, such as coexisting distal obstruction, stricture, or a foreign body.

    Large numbers of viable Giardia muris trophozoites were isolated from the duodenum of experimentally infected mice 6 days after inoculation with 1,000 G. muris cysts. A series of shaking, incubation, and washing steps in the presence of the broad-spectrum antibiotic piperacillin readily provided 4.9 +/- 1.5 x 10(5) G. muris trophozoites per mouse, free of detectable contaminant organisms. Anaerobic and microaerophilic culturing and scanning electron microscopy demonstrated axenic status and high purity of the isolates. The viability of trophozoites was 98 +/- 2%. Application of this technique should permit novel immunological and epidemiological analyses of G. muris infection and biochemical investigations of this protozoan parasite.

    Full Text Available Abstract Introduction A pancreatic pseudocyst is a common sequela of severe acute pancreatitis. Commonly, it presents with abdominal pain and a mass in the epigastrium several weeks after the acute episode and can be managed conservatively, endoscopically or surgically. We report a patient with a pancreatic pseudocyst awaiting endoscopic therapy who developed a life-threatening complication following a rather innocuous trauma to the abdomen. Case presentation A 23-year-old Asian male student presented as an emergency with an acute abdomen a week after a minor trauma to his upper abdomen. The injury occurred when he was innocently punched in the abdomen by a friend. He experienced only moderate discomfort briefly at the time. His past medical history included coeliac disease and an admission four months previously with severe acute pancreatitis. He was hospitalized for 15 days; his pancreatitis was thought to be due to alcohol binge drinking on weekends. Ultrasound scanning showed no evidence of gallstone disease. Five days after the trauma, he became anorexic, lethargic and feverish and started vomiting bilious content. Seven days post-trauma, he presented to our emergency department with severe abdominal pain. An emergency laparotomy was performed where a transverse linear duodenal laceration was found at the junction of the first and second part of his duodenum, with generalized peritonitis. His stomach and duodenum were stretched over a large pancreatic pseudocyst posterior to his stomach. It was postulated that an incomplete duodenal injury (possibly a serosal tear occurred following the initial minor trauma, which was followed by local tissue necrosis at the injury site resulting in a delayed presentation of generalized peritonitis. Conclusion This is the first reported case of a traumatic duodenal laceration following minor blunt trauma in the presence of a large pancreatic pseudocyst. Minor blunt abdominal trauma in a normal healthy adult

    Copper deficiency is a known cause of anemia and neutropenia that is easily remedied with copper supplementation. Copper is primarily absorbed in the stomach and proximal duodenum, so patients receiving enteral nutrition via methods that bypass this critical region may be at increased risk for copper deficiency. In pediatrics, postpyloric enteral feeding is increasingly utilized to overcome problems related to aspiration, severe reflux, poor gastric motility, and gastric outlet obstruction. However, little is known about the prevalence of copper deficiency in this population. We describe three pediatric patients receiving exclusive jejunal feeds who developed cytopenias secondary to copper deficiency. © 2017 Wiley Periodicals, Inc.

    Posttraumatic pancreatic rupture is associated with high morbidity and mortality. Various management strategies are described, but due to the relative rarity of this pathology no standards exist. We reported a 21 years old male with post traumatic complete rupture of the pancreatic isthmus,devascularization lesion of descending duodenum, right renal artery posttraumatic thrombosis and left lobe of the liver laceration. Laparotomy for hemostasis was initially performed in a different hospital and the patient was then referred to us.Pancreaticoduodenectomy and right nephrectomy were performed. Postoperatively the patient had a pancreaticojejunal anastomosis fistula spontaneously resolved at 45 days.Pancreaticoduodenectomy can in selected cases be a solution in pancreatic trauma. Celsius.

    1953-01-01

    Traumatic pancreatitis should be considered as a diagnostic possibility when trauma to the epigastrium is followed by phenomena suggestive of intra-abdominal injury. The presence or absence of hyperamylasemia should be established immediately. Even when traumatic pancreatitis is believed to exist, any suggestion of injury to other viscera should indicate laparotomy. Retroperitoneal rupture of the duodenum may simulate traumatic pancreatitis in all respects, including hyperamylasemia. X-ray studies may be of value in differentiation. Non-complicated traumatic pancreatitis is best treated conservatively. Gunshot and knife wounds of the pancreas should be drained. PMID:13094537

Injuries to the portal vein were always associated with complete rupture of the pancreas, requiring distal pancreatic resection in four cases and a duodenum preserving resection of the head of the pancreas in one. In two of these patients the portal vein had to be reconstructed with a Goretex prosthetic graft. Mortality was 14.7% for the whole group (n = 68 and 0% for patients with additional portal venous injuries.

    There are a number of surgical strategies for the treatment of chronic pancreatitis. The optimal intervention should provide effective pain relief, improve/maintain quality of life, preserve exocrine and endocrine function, and manage local complications. Pancreaticoduodenectomy was once the standard operation for patients with chronic pancreatitis; however, other procedures such as the duodenum-preserving pancreatic head resections and its variants have been introduced with good long-term results. Pancreatic duct drainage via a lateral pancreaticojejunostomy continues to be effective in ameliorating symptoms and expediting return to normal lifestyle in many patients. This review summarizes operative indications and gives an overview of the different surgical strategies in treating chronic pancreatitis.

    Noonan syndrome, which is a multiple congenital disorder, may be associated with lymphatic abnormalities. Protein-losing enteropathy (PLE) developing in Noonan syndrome is rare. We performed transnodal lymphangiography by directly accessing bilateral inguinal nodes under ultrasound guidance in a 17-year-old female with PLE developing in Noonan syndrome to assess detailed anatomical findings regarding lymphatic vessels. There have been no reports on transnodal lymphangiography for Noonan syndrome. Post-lymphangiographic CT images revealed multiple lymphatic abnormalities and lipiodol extravasation into the duodenum and the proximal jejunum. Transnodal lymphangiography was easy and safe for PLE developing in Noonan syndrome, and post-lymphangiographic CT provided invaluable information.

    We report the case of a 66-year-old female who presented with jaundice secondary to recurrent adenocarcinoma of the gallbladder and several common bile duct stones. Percutaneous papillary dilatation was planned to remove the common bile duct stones. Papilla was dilated through the percutaneous approach with an 8-mm peripheral cutting balloon instead of a standard balloon. All the stones were pushed successfully into the duodenum with a saline flush. No complications were encountered. Use of a peripheral cutting balloon for dilatation of the papilla seems to be safe and effective because it has the advantage of controlled incision and dilatation of the target at low pressures.

    Aortoenteric fistula is a rare but significant clinical entity associated with high morbidity and mortality if remain untreated. Clinical presentation and imaging findings may be subtle and prompt diagnosis can be difficult. Herein, we present a patient who initially presented with abdominal pain and computed tomography showed an aortic aneurysm compressing duodenum without any air bubbles. One month later, the patient presented with gastrointestinal bleeding and computed tomography revealed air bubbles within aneurysm. With a diagnosis of aortoenteric fistula, endovascular aneurysm repair was carried out. This case uniquely presented the computed tomography findings in progression of an aneurysm to an aortoenteric fistula

    Absorption of 239 Pu was measured in neonatal swine gavaged with either 239 Pu(IV) or 239 Pu(VI) niitrate 1 day after birth. When they were killed, 1 or 3 wk later, retention of the Pu(VI) was about 50% greater than retention of Pu(IV). Studies with isolated intestinal segments indicated no appreciable difference in 238 Pu transport by the duodenum, midgut or terminal ileum, and a substantial decrease in absorption between 2 and 19 days after birth

    A decrease in the defense capacity of the body combined with penetration of intestinal microorganisms through the intestinal wall causes severe, often lethal complications of the acute radiation disease. We followed the clinical symptoms, the changes of hematological parameters and the changes of the composition of intestinal microflora in laboratory rats irradiated by a single, whole-body dose of 15 Gy gamma-rays. An increase of the common microflora in duodenum, liver and in oral cave and leucopenia in peripheral blood have been observe in all time intervals followed. The changes in red blood cells were characterized by anemia, manifesting clinically in hemorrhages and bloody diarrhea. (authors)

In one of these, an intramural hematoma of the duodenum was associated with chronic pancreatitis. A cause was not found in the second dog. The third dog, which had clinical and radiographic evidence of gastric dilatation, was found at surgery to have hemoperitoneum associated with a ruptured intramural intestinal hematoma. In 1 dog, the hematoma was evacuated through a serosal incision. In the other 2 dogs, the problem was resolved by resection of the involved segment of intestine, followed by anastomosis. All 3 dogs recovered without complications.

    An eight-year-old, neutered, female English springer spaniel was presented with a 14-month history of vomiting, marked weight loss and lethargy, all of which were non-responsive to medical therapy. Abdominal radiographs and ultrasonography showed an intraluminal soft tissue mass extending from the pyloric antrum to the proximal duodenum. Two spherical masses both approximately 8 cm in diameter were removed via a duodenotomy. Histopathological examination showed the first mass to be a trichobezoar and the aboral mass to be a Brunner's gland adenoma. Surgery resulted in a complete resolution of the clinical signs. © 2011 British Small Animal Veterinary Association.

    Aortoenteric fistula (AEF) and aortoenteric erosion (AEE) are deadly and difficult to diagnose. We present here a case report of a patient with a delayed diagnosis of AEF whose preoperative imaging revealed a large vertebral osteophyte which likely directed the aortic impulse into the duodenum. We believe this is the first report documenting an anatomical explanation for AEF/AEE and conclude that the presence of vertebral osteophytes should be considered a risk factor when assessing preoperative likelihood of AEF/AEE.

    The spectrum of this disease has undergone major changes since 1932 when Crohn, Ginzberg and Oppenheimer differentiated Ileitis terminalis from nonspecific inflammations of the bowels. Initially, Crohn assumed an inflammation restricted to the terminal ileum. Today, Crohn's disease has been verified to affect the total gastro-intestinal tract from the cavity of the mouth to the anus. In 1949 Ross et al. were the first to report Crohn's disease in the region of the stomach and duodenum. Its localization in the upper intestinal tract, however, is a rare occurrence on the whole.

    A 48-year-old woman with a history of diabetes was admitted for nausea and vomiting with body weight loss. A blood examination revealed high plasma glucose and thyroid hormone levels and metabolic acidosis. She was therefore diagnosed with both diabetic ketoacidosis (DKA) and hyperthyroidism. Nausea and vomiting continued intermittently despite the administration of saline and insulin. The patient was further diagnosed with superior mesenteric artery syndrome (SMAS) after abdominal computed tomography revealed that a horizontal portion of the duodenum was sandwiched between the aorta and the superior mesenteric artery. Clinicians should be vigilant for SMAS in patients with both DKA and hyperthyroidism who present body weight loss.

    The changes were studied in the metabolism of protein using albumin- 125 I in seven patients with benign conditions of the stomach or duodenum before gastrectomy and starting with the second week after the surgery. In the postoperative period body weight was found to be significantly reduced, there was a drop in erythrocyte count, and blood hemoglobin and plasma albumin concentration were decreased. There was a significant rise of plasma volume during this period. Compared with the preoperative findings, the intravascular albumin pool was diminished by 11%, the extravascular albumin pool by 19.%, so that the overall albumin pool was postoperatively found to be reduced by 1/6.

    Laparoscopic resection of stomach was done in 84 patients with complicated peptic ulcer of stomach and duodenum. There were 1.2% post-operative complications in case of laparoscopic resection of stomach in comparison with open resection, which had 33.3% complications. There were not deaths in case of laparoscopic resection of stomach. This indication was about 4% in patients after open resection. It was determined that functionalefficiency afterlaparoscopic resection was in 1.6-1.8 times higher than afteropen resectionof stomach.

    Duodenal duplication cysts (DDC) are rare congenital anomalies that usually present in infancy and childhood. Acute presentation in adults is even rarer. We report a case of a 34-year-old man who presented with recurrent acute pancreatitis and was found to have a cystic lesion in the second part of his duodenum. Further investigations revealed communication between the cystic lesion and the distal common bile duct. We describe the details of the operative approach taken to resect the DDC. We describe the differential diagnoses and the criteria for diagnosing DDC. Management options for DDC are discussed along with our recommendations.

    Full Text Available A submucosal lymphangioma is a rare pathology in the alimentary tract. It is a benign entity of the lymphatic system. A duodenal lymphangioma is extremely rare and has an unknown etiology. Clinical and laboratory findings are nonspecific, and they are incidentally found by endoscopy and their treatment is surgical excision. Small lesions are often asymptomatic. Recently, the authors experienced a 62-year-old man, who had a duodenal lymphangioma, showing gastric outlet obstruction symptoms. A multidetector computed tomography abdomen study revealed a single submucosal cystic lesion in second part of duodenum. The lesion was successfully excised after Whipple′s procedure. Histopathology confirmed the diagnosis of lymphangioma.

    Full Text Available Literature has been showing a tendency of reducing the limits of Whipple's resection. The main technical advance was the pylorus preserving resection, technique proposed by Traverso and Longmire in 1978. The pancreticoduodenectomy for chronic pancreatitis, is probably the best opportunity to apply this type of procedure. In these specific patients, the author preserved the pylorus and the third portion of the duodenum. The gastrointestinal transit was reconstructed by the duodenumduodenal anastomosis and the bile duct and the pancreas were drained in a Roux-en-way loop . Follow-up showed no important complication, with no problems related to gastric emptying and without pain.

    A proteolytic enzyme, ingobsin , purified from rat duodenal extracts is shown to be localised to intestinal goblet cells of both man and rat. Enzyme positive cells decrease in number from duodenum to colon. The enzyme is a 33 000 Mr protein with an isoelectric point of 5.1. The pH optimum...... for enzymatic activity is 7.4-8.0. Based on substrate specificity for arg-x, lys-x and to a lesser degree tyr-x, on the effect of diisopropylphosphorofluoride , Trasylol and phenylmethylsulfonylfluoride and on proteolytic activity towards intact proteins, ingobsin is classified as a serine proteinase...

    Full Text Available Antroduodenal motility disorder is a major component of the pathogenesis of most diseases of the upper gastrointestinal tract. Motility regulation is a complex process and it is accomplished by complex balanced neurohumoral mechanisms and depends on the chemical composition of the chyme and on the change in the cyclic membrane potential — slow waves that generate myogenic pacemakers. The electrical activity of the stomach and duodenum may be assessed by electrogastroenterography that shows the motor evacutory function of these digestive tract segments and helps choose therapy for its disorders.

    The purpose of this study is to present selected computed tomography (CT) images showing unusual causes of obstructive jaundice. We reviewed retrospectively the Ct findings of obstructive jaundice in 227 patients. The most common causes of biliary obstruction were adenocarcinoma of the pancreatic head (n=77) and cholangiocarcinoma (n=65). In 13 cases (5.7%), the etiology of obstructive jaundice was unusual or exceptional: tuberculous adenitis (n=3), obstruction of afferent loop (n=2)signet ring cell adenocarcinoma (n=3); in duodenum, gallbladder and papilla of Water), Mirizzi syndrome (n=1), adenocarcinoma of the hepatic flexure (n=1), choledochal cyst (n=1) and pancreatic lymphoma (n=1).

    BACKGROUND: Cyclooxygenase inhibitors reduce mucosal bicarbonate secretion in the duodenum, but the evidence for their effect on bicarbonate secretion in the stomach remains controversial. We have, therefore, studied how indomethacin influences gastroduodenal bicarbonate secretion and luminal...... healthy volunteers. Bicarbonate and PGE2 were measured in the gastroduodenal effluents by back-titration and radioimmunoassay, respectively. RESULTS: Vagal stimulation and duodenal luminal acidification (0.1 M HCl; 20 ml; 5 min) increased gastroduodenal bicarbonate secretion (p ... markedly inhibited both basal and stimulated gastric and duodenal mucosal bicarbonate secretion, and this reduction was similar to the degree of cyclooxygenase inhibition estimated by the luminal release of PGE2 (p

    This study was conducted to investigate the interaction of obesity and laboratory diets on tissue malondialdehyde levels in rats. Female Zucker obese and lean rats were maintained on either regular grain-based diet or purified casein diet for two weeks, orally gavaged at day 50 with 65 mg/kg DMBA and sacrificed 24 hrs later. Malondialdehyde (MDA) levels were measured in blood and harvested tissues. Data were recorded as mean ± SEM and analyzed statistically. Results show that the obese group on purified casein diet had reduction of MDA levels in the brain, duodenum, liver, lung and kidney tissues as compared to lean group, p <0.05. Obese group on grain-based diet showed significant increase in MDA levels only in the duodenum, p <0.05. We conclude that dietary intervention differentially affects the oxidative markers in obese rats. It appears that purified casein diets were more effective than grain-based diet in reduction of oxidative stress in obese rats.

    Sheep were fitted with rumen cannulas and re-entrant duodenal and T-shaped ileal cannulas and adapted to a semisynthetic phosphorus deficient diet providing approximately 0.96 g P/d and 14 g N/d, about half of which was in the form of urea-N. Phosphorus repletion was achieved by daily intraduodenal infusion of phosphate, bringing up the daily P supply to about 4.2 g. In P depletion, as well as in P repletion, a series of infusion periods of six days each were established with continuous intraruminal infusion of Cr-ethylenediaminetetra acetic acid as a fluid marker and 15 NH 4 Cl as a marker of microbial N. Gastrointestinal phosphorus and nitrogen balances were established and the net yield of microbial N in the rumen and the flow of microbial N into the duodenum were calculated. The following significant findings were obtained in P depleted sheep. The concentrations of P in plasma and in rumen fluid and the flow of P to the small intestines fell by 60 to 90%; the P balances became negative. The gastrointestinal balance and the flow of N before the large intestines were not affected, but N digestibility in the large intestines was reduced. The daily net yield of microbial N in the rumen was reduced by 27% and the daily flow of microbial N into the duodenum was reduced by 26%. (author)

    Endoscopic retrograde cholangiopancreatography (ERCP) rendezvous during laparoscopic cholecystectomy is an efficient and safe method to treat cholecystocholedocholithiasis. Advancing a guidewire through the cystic duct into the duodenum and withdrawing it in the accessory channel of duodenoscope may be, however, laborious. Moreover, rendezvous performed in the typical manner needs the use of several costly accessories. We herein describe a simpler and cheaper method to gain access to the biliary duct at rendezvous. Twenty-four consecutive patients undergoing ERCP rendezvous during laparoscopic cholecystectomy were considered. A catheter was introduced in the cystic duct and advanced into the duodenum. Access to the bile duct was than achieved by means of a precut sphincterotomy performed over the catheter emerging from the papilla. Cannulation was successful in all but two patients, in whom ERCP was performed in the conventional manner. The only complication was a case of mild post-sphincterotomy bleeding. In comparison with the typical rendezvous technique our procedure allowed savings of about 250, since its performance only requires a catheter and a knife sphincterotome. Over-the-catheter precut during ERCP rendezvous is a feasible and safe method which avoids the need for the manipulation of several accessories and guidewires, and thus results in money and time savings.

    A radioimmunoassay for measurement of secretin in the plasma of experimental animals and man has been developed by means of the so-called stripping procedure (pre-treatment of plasma with Quso). The detection limit is about 7 pg/ml at a final dilution of 1:630 000 and an equilibrium constant of 2.1x10 -11 L/M. By means of this system plasma secretin in the species examined can be measured reliably. The coefficients of variation are (percent): The within assay precision (intra-assay) 12, the between assay precision (inter-assay) 23. The median of basal venous plasma secretin are (pg/ml) dog 16, rabbit 0, rat (aorta) 0, rat (porta) 31, man 0. From these studies it is concluded that a) as a consequence of unspecific interference of plasma particles with the secretin RIA-system only a previous removal of these interfering factors leads to reliable test results; should this pre-requisite be neglected falsely too high results are to be expected; b) plasma secretin rises if there is either hydrochloric acid present in the duodenum or if gastric together with food particles reaches the duodenum; c) at least in the dog there may be different molecular species of secretin circulating in the peripherical plasma, however the biological role of these is unknown at present.

    The presence of stones in the common bile duct (CBD) may cause complications such as obstructing jaundice or ascending cholangitis, and the stones should be removed. To assess the efficacy of percutaneous elimination of CBD stones from the gallbladder through the papilla. During a 4 year period, six patients (five men and one woman, mean age 71.5 years) who had CBD stones and an existing gallbladder drain underwent percutaneous stone push into the duodenum after balloon dilatation of the papilla, with a diameter equal to that of the largest stone. Access into the CBD was from the gallbladder, using an already existing percutaneous gallbladder drain (cholecystostomy tube). Each patient had one to three CBD stones measuring 7-14 mm. Successful CBD stone elimination into the duodenum was achieved in five of the six patients. The single failure occurred in a patient with choledochal diverticulum, who was operated successfully. There were no major or minor complications during or after the procedures. Trans-cholecystic CBD stone elimination is a safe and feasible percutaneous technique that utilizes existing tracts, thus obviating the need to create new percutaneous access. This procedure can replace endoscopic or surgical CBD exploration.

    Probiotics, including Bacillus spp. and Lactobacillus, are potential replacements for low dose in-feed antibiotics for pig. This study aimed to evaluate the effect of the co-administration of Bacillus subtilis RJGP16 and Lactobacillus salivarius B1 as potential probiotics to stimulate local immune responses. Thirty two newborn piglets were divided into four groups and orally administrated with different combination of probiotics (none; RJGP16; B1; RJGP16 and B1) at the age of 0, 7 and 11 days. We analysed the parameters of the mucosal immunity of piglets a week after weaning. Our results showed that the gene expression of interleukin (IL)-6 in the duodenum and ileum, porcine beta-defensins (pBD)-2 in the duodenum were significantly increased (p<0.01) with co-administration of the RJGP16 and B1. Also the expression and release of TLR-2 and the number of immunoglobulin (Ig) A producing cells were increased (p<0.01). The results demonstrate that the co-administration of the two bacteria stimulate a more intense mucosal immunity than the administration of each bacterium alone. Copyright © 2012 Elsevier Ltd.

    Full Text Available The aim of the research is to improve the efficiency of diagnosis and treatment of NSAID-induced enteropathy at elderly patients with chronic pain (osteoarthritis, dorsopathy. Material and Methods. 300 elderly with osteoarthritis or dorsopathies regularly (8 weeks or more receiving diclofenac at 75 mg per day were inspected. Clinical features, morphology, components of the diffuse endocrine system of the small intestine were studied. Results. It is defined, that at elderly patients with regular use of NSAIDs in 25% of cases postbulbar erosive duodenitis, in 75% of cases inflammatory and atrophic changes of the distal duodenum were diagnosed. Diagnosis of NSAID-induced enteropathy at elderly should include faecal calprotectin and morphology analysis of postbulbar area of the duodenum. Use meloxicam and sulfasalazine at older patients helps to eliminate or reduce intestinal dyspepsia, malabsorption, and intestinal inflammation on the results of faecal calprotectin and of histology of the small intestine. Conclusion. Elderly patients are at high-risk group for NSAID-induced enteropathy due to functional disturbances in the neuroendocrine system of the small intestine.

    Full Text Available This study was conducted to evaluate the effect of dietary organic zinc (Zn sources on growth performance, the incidence of diarrhoea, serum and tissue Zn concentration, and intestinal morphology in growing rabbits. A total of 120 New Zealand White rabbits aged 35 d and with an initial body weight of 755±15 g, were randomly divided into 4 treatment groups for a 49 d feeding trial. Dietary treatments were designed with different Zn supplements as follows: (1 Control group: 80 mg/kg Zn as ZnSO4; (2 ZnLA group: 80 mg/kg Zn as Zn lactate; (3 ZnMet group: 80 mg/kg Zn as Zn methionine; (4 ZnGly group: 80 mg/kg Zn as Zn glycine. The results showed that, when compared with rabbits fed ZnSO4, supplementation with ZnLA improved (P4. Supplementing with ZnLA increased duodenum villi height (681.63 vs. 587.14 μm, P4, except that feeding ZnMet led to higher (P4. The results indicated that supplementation with 80 mg/kg Zn as ZnLA could improve growth performance, increase liver Zn concentration and enhance duodenum morphology, while reducing the incidence of diarrhoea in growing rabbits.
