Full Text Available Brunner’s gland hamartomas are small benign lesions that are most commonly found in the bulb of the duodenum. They are very uncommon, and most are found incidentally during upper gastrointestinal series or esophagogastroduodenoscopy. The lesions tend to be asymptomatic, but patients may present with symptoms of duodenal obstruction or hemorrhage secondary to ulceration. Histologically, a Brunner's gland hamartoma consists of the components of Brunner's gland cells, as well as glandular, adipose and muscle cells. In this study, we report the case of a 30-year-old man who presented with upper gastrointestinal bleeding and obstructive symptoms due to a giant Brunner's gland hamartoma in the duodenal bulb. The hamartoma was successfully removed by endoscopic resection. No significant complications were observed. Microscopically, the lesion was found to be entirely composed of variable Brunner's glands and adipocytes.

Full Text Available Introduction: Gastrointestinal tuberculosis often involves the ileocecal region. Duodenal and gastric tuberculosis found in only 1% of patients suffering from pulmonary tuberculosis with associated HIV infection in non-endemic areas. Duodenal obstruction due to tuberculosis is very rare and needs high index of suspicions for diagnosis. Mostly this entity is suspected on intraoperative findings. In this manuscript we emphasized on ways and means for establishing histopathological diagnosis before starting anti-tubercular treatment in such cases. Method and Material: All patients of suspected gastroduodenal tuberculosis presented with feature of gastric-outlet obstruction managed during Jan 2009 to June 2011 were included in the study. After proper evaluation (routine hematological and biochemical examination, microbiological examination, serological and endoscopic evaluation exploratory laparotomy was done and if there is no mesenteric lymphadenopathy or it is not safe to take biopsy form the diseased duodenum, multiple FNAC were taken from the diseased portion for histopathological and microbiological diagnosis. Result: A total of five patients were treated during this period. The most common presentation was vomiting followed by failure to thrive and weight loss; two patients had abdominal pain. Biopsy of mesenteric lymph node was possible in two cases. FNAC from diseases portion was taken in all cases. FNAC showed granulomas in four cases. Cases where even FNAC finding was non-conclusive on HPE/Microbiology was not subjected to antitubercular drug. Conclusion: Multiple intra-operative FNAC may be taken from the diseased portion of the duodenum to establish the histopathological diagnosis if diagnosis is not established by any other mean.

Objective: To investigate the clinical effect of metallic stent implantation together with intra-arterial chemotherapy in treating malignant gastric and duodenal obstruction. Methods: A total of 32 patients with malignant gastric and duodenal obstruction were enrolled in this study. The obstructed sites were located at the gastric sinus and pylorus part (n=16), at the gastroduodenal anastomotic stoma (n=6) or at the descending part of duodenum (n=10). Under DSA guidance and with the additional help of endoscopy, a guide-wire was orally placed in the gastroduodenal obstructed site, which was followed by the implantation of the self-expanding metallic stent (Ni-Ti alloy). Postoperative intra-arterial chemotherapy via the tumor-feeding arteries was carried out in 16 patients (dual interventional therapy). The clinical results were analyzed. Results: Successful stent insertion was achieved in all 32 patients (100%). After stent implantation the obstructive symptoms were markedly relieved and the food intake was improved. No serious complications occurred. The median survival time for the 16 patients who had received dual interventional therapy was 9.3 months, while the median survival time for the other 16 patients who had received simple stenting therapy was 5.7 months. Conclusion: For the treatment of inoperable malignant gastroduodenal obstruction, the implantation of metallic self-expanding stents is a technically simple, clinically safe and effective palliative measure. Combined with postoperative intra-arterial chemotherapy, the metal stent implantation can control the tumor growth and elongate the survival time. (authors)

A case of duodenal obstruction by a congenital duodenal web in a 34-year-old woman is presented. A mucosal diaphragm obstructed the duodenum. 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.

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.

To compare the outcome between laparoscopic gastrojejunostomy (LapGJ) and duodenal stenting (DS) in terms of oral intake, nutritional status, patency duration, effect on chemotherapy and survival. Medical records of 115 patients, who had LapGJ or duodenal stent placement between July 2005 and September 2015 in Seoul National University Bundang Hospital, have been reviewed retrospectively. Oral intake was measured with Gastric Outlet Obstruction Scoring System. Serum albumin and body weight was measured as indicators of nutritional status. The duration of patency was measured until the date of reintervention. Chemotherapy effect was calculated after the procedures. Survival period and oral intake was analyzed by propensity score matching age, sex, T-stage, comorbidities, and chemotherapy status. Forty-three LapGJ patients and 58 DS patients were enrolled. Improvement in oral intake was shown in LapGJ group versus DS group (88% vs. 59%, P = 0.011). Serum albumin showed slight but significant increase after LapGJ (+0.75 mg/dL vs. -0.15 mg/dL, P = 0.002); however, there was no difference in their body weight (+5.1 kg vs. -1.0 kg, P = 0.670). Patients tolerated chemotherapy longer without dosage reduction after LapGJ (243 days vs . 74 days, P = 0.006) and maintained the entire chemotherapy regimen after the procedure longer in LapGJ group (247 days vs. 137 days, P = 0.042). LapGJ showed significantly longer survival than DS (220 vs. 114 days, P = 0.004). DS can provide faster symptom relief but LapGJ can provide improved oral intake, better compliance to chemotherapy, and longer survival. Therefore, LapGJ should be the first choice in gastric outlet obstruction patients for long-term and better quality of life.

Duodenal Obstruction by a Gallstone (Bouveret's Syndrome Managed by Endoscopic Stone Extraction: A Case Report and Review

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.

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.

2015-01-01

Full Text Available Duodenal duplications in adults are exceedingly rare and their diagnosis remains difficult as symptoms are largely nonspecific. Clinical presentations include pancreatitis, biliary obstruction, gastrointestinal bleeding from ectopic gastric mucosa, and malignancy. A case of duodenal duplication in a 59-year-old female is presented, and her treatment course is reviewed with description of combined surgical and endoscopic approach to repair, along with a review of historic and current recommendations for management. Traditionally, gastrointestinal duplications have been treated with surgical resection; however, for duodenal duplications, the anatomic proximity to the biliopancreatic ampulla makes surgical management challenging. Recently, advances in endoscopy have improved the clinical success of cystic intraluminal duodenal duplications. Despite these advances, surgical resection is still recommended for extraluminal tubular duplications although combined techniques may be necessary for long tubular duplications. For duodenal duplications, a combined approach of partial excision combined with mucosal stripping may offer advantage.

Anomalous pancreatic ductal system allowing distal bowel gas with duodenal atresia

Bypass of the atretic duodenal segment through an anomalous pancreatic ductal system is a rare anomaly described in the literature in only a handful of cases. This case report highlights the importance of considering duodenal atresia and pancreaticobiliary enteric bypass in the differential diagnosis of neonates presenting with partial duodenal obstruction. On ultrasound, the presence of gas in the biliary tree or pancreatic duct should alert the physician to the possibility of duodenal atresia with congenital pancreaticobiliary duct anomalies that allow for bypass of enteric contents, including air, into more distal bowel, thereby creating a gas pattern aptly described as double bubble with distal gas.

A 10-month-old German Shepherd Dog presented for evaluation of intermittent vomiting. Abdominal radiographs revealed a marked right cranial mass effect. Initial differentials included abscess/cyst or less likely neoplasia from undetermined origin. On abdominal ultrasound the mass appeared cystic and thin walled. Computed tomography revealed a large cystic lesion originating from the pyloroduodenal junction causing pyloric outflow obstruction. A noncommunicating duodenal duplication cyst was found on exploratory laparotomy and further confirmed with histopathology and immunohistochemistry. Enteric duplication cyst should be considered as a differential in young dogs with gastrointestinal signs and a cystic abdominal mass detected with different imaging modalities. © 2017 American College of Veterinary Radiology.

2008-04-01

Full Text Available Spontaneous intramural duodenal haematoma (IDH is an uncommon pathology and it is usually related to anticoagulant therapy. Other causes include various pancreatic diseases, connective tissue disease, peptic ulcer disease and pancreaticoduodenal aneurysm. IDH of pancreatic origin has been infrequently reported. The disease course can be life-threatening and serious complications may occur, including gastric outlet obstruction, duodenal perforation and septicaemia. A case of pancreatic-induced IDH is presented, for which pancreaticoduodenectomy was performed as definitive treatment. In general, medical treatment with continuous nasogastric aspiration and total parenteral nutrition is recommended as initial management strategy. Surgical interventions (evacuation of blood clot or surgical resection are reserved for patients in whom medical treatment fails or complications occur.

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.

Intramural Duodenal Haematoma after Endoscopic Biopsy: Case Report and Review of the Literature

Directory of Open Access Journals (Sweden)

Claudia Grasshof

2012-01-01

Full Text Available The development of intramural duodenal haematoma (IDH after small bowel biopsy is an unusual lesion and has only been reported in 18 children. Coagulopathy, thrombocytopenia and some special features of duodenal anatomy, e.g. relatively fixed position in the retroperitoneum and numerous submucosal blood vessels, have been suggested as a cause for IDH. The typical clinical presentation of IDH is severe abdominal pain and vomiting due to duodenal obstruction. In addition, it is often associated with pancreatitis and cholestasis. Diagnosis is confirmed using imaging techniques such as ultrasound, magnetic resonance imaging or computed tomography and upper intestinal series. Once diagnosis is confirmed and intestinal perforation excluded, conservative treatment with nasogastric tube and parenteral nutrition is sufficient. We present a case of massive IDH following endoscopic grasp forceps biopsy in a 5-year-old girl without bleeding disorder or other risk for IDH, which caused duodenal obstruction and mild pancreatitis and resolved within 2 weeks of conservative management. Since duodenal biopsies have become the common way to evaluate children or adults for suspected enteropathy, the occurrence of this complication is likely to increase. In conclusion, the review of the literature points out the risk for IDH especially in children with a history of bone marrow transplantation or leukaemia.

Full Text Available Congenital duodenal atresia complicated by gastric perforation (GP is a very rare and a very mortal condition. Only three newborns could be cured in the reported 13 cases. We report a successfully treated newborn with this complicated disease. A 2-day-old male was hospitalized with prediagnosis of duodenal obstruction. Twelve hours later, significant abdominal distention occurred promptly. At laparotomy, GP and preampullary duodenal atresia were detected. Gastrorrhaphy and duodenoduodenostomy were performed in the same operation. The patient was discharged on the 15th postoperative day. This complicated disease can be treated by early diagnosis and surgical intervention. We choose one-stage operation because of the clean peritoneal cavity. However, generalized peritonitis may require two-stage operation in delayed cases.

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.

Full Text Available Introduction. Duodenal duplication cyst (DDC is a rare congenital malformation that appears in the embryonic development of the digestive tract. It is a benign condition usually diagnosed in infancy and early childhood, being a rare and difficult diagnosis in adult population. DDC is a recognized cause of duodenal obstruction, acute pancreatitis, obstructive jaundice and even digestive hemorrhage. Case presentation. We report the case of a young adult male with abdominal pain history, who presents with recurrent episodes of acute severe necrotic pancreatitis. The abdominal computed tomography scan revealed a Balthazar C necrotic pancreatitis with partial thrombosis of the splenic vein and a cystic mass in the second part of the duodenum. The endoscopic ultrasonography (EUS established that the duodenal cystic lesion came from the second layer, meaning the submucosa. We performed endoscopic cystotomy with complete evacuation of the fluid content into the duodenum, with favorable clinical outcome. Conclusions. The particularity of the case is represented by the low incidence of this pathology and the rare form of presentation, meaning acute pancreatitis probably from pancreatic ductular hypertension caused by the DDC.

2010-11-01

Full Text Available Abstract Introduction Cases of gallstone ileus account for 1% to 4% of all instances of mechanical bowel obstruction. The majority of obstructing gallstones are located in the terminal ileum. Less than 10% of impacted gallstones are located in the duodenum. A gastric outlet obstruction secondary to a gallstone ileus is known as Bouveret syndrome. Gallstones usually enter the bowel through a biliary enteral fistula. Little is known about the formation of such fistulae in the course of gallstone disease. Case presentation We report the case of a 72-year-old Caucasian woman born in Germany with a gastric outlet obstruction due to a gallstone ileus (Bouveret syndrome, with a large gallstone impacted in the third part of the duodenum. Diagnostic investigations of our patient included plain abdominal films, gastroscopy and abdominal computed tomography, which showed a biliary enteric fistula between the gallbladder and the duodenal bulb. Our patient was successfully treated by laparotomy, duodenotomy, extraction of the stone, cholecystectomy, and resection of the fistula in a one-stage surgical approach. Histopathological examination showed chronic and acute cholecystitis, with perforated ulceration of the duodenal wall and acute purulent inflammation of the surrounding fatty tissue. Four months prior to developing a gallstone ileus our patient had been hospitalized for cholecystitis, a large gallstone in the gallbladder, cholangitis and a small obstructing gallstone in the common biliary duct. She had been treated with endoscopic retrograde cholangiopancreatography, endoscopic biliary sphincterotomy, balloon extraction of the common biliary duct gallstone, and intravenous antibiotics. At the time of her first presentation, abdominal ultrasound and endoscopic examination (including esophagogastroduodenoscopy and endoscopic retrograde cholangiopancreatography had not shown any evidence of a biliary enteral fistula. In the four months preceding the

The purpose of this study is to evaluate the radiologic findings of the intestinal obstruction in the neonate according to the causes and to determine the findings useful for the differential diagnosis. The materials consisted of 29 neonates with surgically proven gastrointestinal tract obstruction. We analyzed simple abdominal radiography and barium study comparing with the operative findings. The causes of intestinal obstruction were gastric atresia in 1 case, duodenal atresia in 3 cases, small bowel atresia in 11 cases (jejunal; 3 cases, ileal; 8 cases), colonic atresia in 2 cases, Hirschsprung's disease in 9 cases, ano-rectal anomaly in 6 cases, midgut volvulus in 2 cases, and Meckel's diverticulum in 1 case. Vomiting was noted in the all cases. The abdominal distension was not noted in the cases of gastric atresia, duodenal atresia, and proximal jejunal atresia. The meconium passage was noted in 2 cases of ileal atresia and 3 cases of Hirschsprung's disease. On barium study, site of obstruction was predicted accurately in gastric atresia, duodenal atresia, proximal jejunal atresia, and colonic atresia but it was not possible in distal jejunal atresia and ileal atresia. The microcolon was noted in 2 cases of jejunal atresia, 4 cases of ileal atresia, and 2 cases of colonic atresia. Out of 9 Hirschsprung's disease transition zones were seen on rectum or rectosigmoid junction in 7 cases and barium study was normal in 2 cases. In the diagnosis of neonatal intestinal obstruction, the basic radiologic studies such as simple abdominal radiography and gastrointestinal contrast study was useful for the differential diagnosis of the proximal bowel loop atresia colonic atresia, and midgut volvulus.

Self-expandable metal stents (SEMSs) can be used for the palliation of malignant obstruction in the upper gastrointestinal tract. This study assessed the feasibility and efficacy of endoscopically inserted SEMSs for the palliation of malignant obstruction in the stomach and duodenum. Between January 2011 and April 2014, 220 patients with gastric or duodenal obstruction due to malignancy underwent endoscopic SEMS insertion at Asan Medical Center. The associations of technical/clinical outcomes and complications with the type of stent and site of obstruction were analyzed. The 220 patients included 125 men (56.8 %) and 95 women (43.2 %); median patient age was 63 years. Fully covered, partially covered, and uncovered SEMSs were inserted into 16, 77, and 120 patients, respectively. Obstructions were located in the gastric outlet, including the duodenal bulb, in 106 patients, and in the duodenal second and third portions in 114 patients. Technical success was achieved in 213 of 220 patients (96.8 %) and clinical success in 184 of 213 (86.4 %). Clinical success rates were similar to the type of stent, but were significantly greater for gastric outlet (95/104, 91.3 %) than for duodenal (89/109, 81.7 %) obstructions (p = 0.039). Stent migration was observed in 20 patients (9.1 %) and stent obstruction in 51 (23.2 %). Rates of stent migration were significantly higher for fully covered (6/16, 37.5 %) than for partially covered (7/77, 9.1 %) and uncovered (7/120, 5.8 %) SEMSs (p stent obstruction were similar for fully covered (2/16, 12.5 %), partially covered (17/77, 22.1 %), and uncovered (32/120, 26.7 %) SEMSs (p = 0.409) and in patients with gastric outlet (26/104, 25.0 %) and duodenal (25/109, 22.9 %) obstruction (p = 0.724). SEMS selection for malignant obstruction of the upper gastrointestinal tract depends on the site of obstruction.

Closed duodenal loops may be made in dogs by ligatures placed just below the pancreatic duct and just beyond the duodenojejunal junction, together with a posterior gastro-enterostomy. These closed duodenal loop dogs die with symptoms like those of patients suffering from volvulus or high intestinal obstruction. This duodenal loop may simulate closely a volvulus in which there has been no vascular disturbance. Dogs with closed duodenal loops which have been washed out carefully survive a little longer on the average than animals with unwashed loops. The duration of life in the first instance is one to three days, with an average of about forty-eight hours. The dogs usually lose considerable fluid by vomiting and diarrhea. A weak pulse, low blood pressure and temperature are usually conspicuous in the last stages. Autopsy shows more or less splanchnic congestion which may be most marked in the mucosa of the upper small intestine. The peritoneum is usually clear and the closed loop may be distended with thin fluid, or collapsed, and contain only a small amount of pasty brown material. The mucosa of the loop may show ulceration and even perforation, but in the majority of cases it is intact and exhibits only a moderate congestion. Simple intestinal obstruction added to a closed duodenal loop does not modify the result in any manner, but it may hasten the fatal outcome. The liver plays no essential role as a protective agent against this poison, for a dog with an Eck fistula may live three days with a closed loop. A normal dog reacts to intraportal injection and to intravenous injection of the toxic substance in an identical manner. Drainage of this loop under certain conditions may not interfere with the general health over a period of weeks or months. Excision of the part of the duodenum included in this loop causes no disturbance. The material from the closed duodenal loops contains no bile, pancreatic juice, gastric juice, or split products from the food. It can be

Full Text Available Abstract Background Malignant gastric outlet obstruction (GOO is commonly seen in patients with advanced gastric-, pancreatic-, duodenal, hepatobiliary or metastatic malignancies. Ten to 25% of patients with pancreatic cancer will develop duodenal obstruction during the course of the disease. Duodenal stenting with self-expandable metal stents is an alternative treatment to surgical bypass procedures. Our aim was to review the published literature regarding treatment of malignant GOO with stents to reveal whether the information provided is sufficient to evaluate the clinical effects of this treatment Methods A literature search from 2000 – 2007 was conducted in Pub Med, Embase, and Cochrane library, combining the following search terms: duodenal stent, malignant duodenal obstruction, gastric outlet obstruction, SEMS, and gastroenteroanastomosis. All publications presenting data with ≥ 15 patients and only articles written in English were included and a review focusing on the following parameters were conducted: 1 The use of graded scoring systems evaluating clinical success; 2 Assessment of Quality of life (QoL before and after treatment; 3 Information on stent-patency; 4 The use of objective criteria to evaluate the stent effect. Results 41 original papers in English were found; no RCT's. 16 out of 41 studies used some sort of graded scoring system. No studies had objectively evaluated QoL before or after stent treatment, using standardized QoL-questionnaires, 32/41 studies reported on stent patency and 9/41 performed an oral contrast examination after stent placement. Objective quantitative tests of gastric emptying had not been performed. Conclusion Available reports do not provide sufficient relevant information of the clinical outcome of duodenal stenting. In future studies, these relevant issues should be addressed to allow improved evaluation of the effect of stent treatment.

Pancreatic heterotopia (PH) is defined as ectopic pancreatic tissue outside the normal pancreas and its vasculature and duct system. Most frequently, PH is detected incidentally by histopathological examination. The aim of the present study was to analyze a large single-center series of duodenal PH with respect to the clinical presentation. A prospective pancreatic database was retrospectively analyzed for cases of PH of the duodenum. All pancreatic and duodenal resections performed between January 2000 and October 2015 were included and screened for histopathologically proven duodenal PH. PH was classified according to Heinrich's classification (Type I acini, ducts, and islet cells; Type II acini and ducts; Type III only ducts). A total of 1274 pancreatic and duodenal resections were performed within the study period, and 67 cases of PH (5.3%) were identified. The respective patients were predominantly male (72%) and either underwent pancreatoduodenectomy (n = 60); a limited pancreas resection with partial duodenal resection (n = 4); distal pancreatectomy with partial duodenal resection (n = 1); total pancreatectomy (n = 1); or enucleation (n = 1). Whereas 65 patients (83.5%) were asymptomatic, 11 patients (18.4%) presented with symptoms related to PH (most frequently with abdominal pain [72%] and duodenal obstruction [55%]). Of those, seven patients (63.6%) had chronic pancreatitis in the heterotopic pancreas. The risk of malignant transformation into adenocarcinoma was 2.9%. PH is found in approximately 5% of pancreatic or duodenal resections and is generally asymptomatic. Chronic pancreatitis is not uncommon in heterotopic pancreatic tissue, and even there is a risk of malignant transformation. PH should be considered for the differential diagnosis of duodenal lesions and surgery should be considered, especially in symptomatic cases.

An unusual cause of intestinal obstruction in an adolescent: a case report

Full Text Available A 15-year-old boy presented with intestinal obstruction two weeks following a blunt abdominal trauma. He had progressive bilious vomiting without abdominal distension or peritonitis. The contrast computed tomography (CT scan of the abdomen provided the definitive diagnosis: there was an obstructing duodenal hematoma, which might have been slowly progressing or have arisen from secondary hemorrhage after the initial injury. The boy remained stable over a ten-day period of conservative treatment, and his obstructive symptoms and signs were resolved completely. A follow-up CT scan of the abdomen (16 days after admission showed an almost complete resolution of the hematoma. Delayed duodenal hematoma causing intestinal obstruction has been reported rarely in previous literature. Occasionally a significant secondary hemorrhage resulting in intestinal obstruction can become life threatening. Clinical follow-up is paramount after initial recovery. Although conservative treatment suffices in most cases, the surgeon should be wary of the need for definitive surgical intervention if there is evidence of ongoing acute hemorrhage or of the obstructing hematoma failing to resolve. Laparoscopic drainage of the hematoma provides optimistic results for patients failing conservative management.

AIM: To determine the safety and efficacy of endoscopic duodenal stent placement in patients with malignant gastric outlet obstruction. METHODS: This prospective, observational, multicenter study included 39 consecutive patients with malignant gastric outlet obstruction. All patients underwent endoscopic placement of a nitinol, uncovered, self-expandable metal stent. The primary outcome was clinical success at 2 wk after stent placement that was defined as improvement in the Gastric Outlet Obstruction Scoring System score relative to the baseline. RESULTS: Technical success was achieved in all duodenal stent procedures. Procedure-related complications occurred in 4 patients (10.3%) in the form of mild pneumonitis. No other morbidities or mortalities were observed. The clinical success rate was 92.3%. The mean survival period after stent placement was 103 d. The mean period of stent patency was 149 d and the patency remained acceptable for the survival period. Stent dysfunction occurred in 3 patients (7.7%) on account of tumor growth. CONCLUSION: Endoscopic management using duodenal stents for patients with incurable malignant gastric outlet obstruction is safe and improved patients’ quality of life. PMID:27076769

A 40-year-old previously healthy white man presented to the emergency department at American University of Beirut Medical Center, Beirut, Lebanon, with severe upper abdominal pain of 36-hour duration. The pain started a few hours after the intake of a single tablet of tiaprofenic acid and became more intense after the intake of another tablet 24 hours later. He had no other symptoms. He had no prior upper gastrointestinal (GI) symptoms, ulcer disease, steroidal or nonsteroidal anti-inflammatory drug use, or ethanol intake. Physical examination revealed mild upper abdominal tenderness. Complete blood count, amylase, lipase, and liver function tests were unremarkable. Computed tomography of the abdomen showed marked thickening of the duodenal wall with surrounding mesenteric streaking. Upper GI endoscopy revealed extensive ulceration involving the duodenal bulb, apex, and proximal D2, as well as a few gastric erosions. Histopathologic examination of duodenal biopsy samples showed extensive epithelial cell necrosis and infiltration of the lamina propria with neutrophils and eosinophils. The patient responded well to rabeprazole 20 mg BID and remains well 5 months later. We performed a literature search of PubMed for all English-language articles published between January 1970 and present (June 2007) using the key words tiaprofenic acid, nonsteroidal anti-inflammatory drugs, NSAID, duodenitis, duodenal erosion, duodenal ulcer, gastritis, gastric erosion, gastric ulcer, or peptic ulcer. We reviewed all randomized controlled trials involving NSAIDs found using PubMed, with a focus on their GI adverse effects. Based on the PubMed search, there were no published reports of acute transmural duodenitis and complicated duodenal ulcers associated with short-term exposure to tiaprofenic acid or other NSAIDs. The Naranjo adverse drug reaction (ADR) probability scale was used and a score of 6 was obtained, indicating a probable ADR from tiaprofenic acid use. We report a patient

Full Text Available Objective. Duodenal atresia (DA routinely has been corrected by laparotomy and duodenoduodenostomy with excellent long-term results. We revisited the patients with DA treated in the last 12 years (2004–2016 comparing the open and the minimally invasive surgical (MIS approach. Methods. We divided our cohort of patients into two groups. Group 1 included 10 patients with CDO (2004–09 treated with open procedure: 5, DA; 3, duodenal web; 2, extrinsic obstruction. Three presented with Down’s syndrome while 3 presented with concomitant malformations. Group 2 included 8 patients (2009–16: 1, web; 5, DA; 2, extrinsic obstruction. Seven were treated by MIS; 1 was treated by Endoscopy. Three presented with Down’s syndrome; 3 presented with concomitant malformations. Results. Average operating time was 120 minutes in Group 1 and 190 minutes in Group 2. In MIS Group the visualization was excellent. We recorded no intraoperative complications, conversions, or anastomotic leakage. Feedings started on 3–7 postoperative days. Follow-up showed no evidence of stricture or obstruction. In Group 1 feedings started within 10–22 days and we have 1 postoperative obstruction. Conclusions. Laparoscopic repair of DA is one of the most challenging procedures among pediatric laparoscopic procedures. These patients had a shorter length of hospitalization and more rapid advancement to full feeding compared to patients undergoing the open approach. Laparoscopic repair of DA could be the preferred technique, safe, and efficacious, in the hands of experienced surgeons.

Full Text Available 【Abstract】Duodenal trauma is uncommon but nowadays seen more and more frequently due to the increased automobile accidents and violent events. The management of duodenal trauma can be complicated, especially when massive injury to the pancreatic-duodenal-biliary complex occurs simultaneously. Even the patients receive surgeries in time, multiple postoperative complications and high mortality are common. To know and manage duodenal trauma better, we searched the recent related literature in PubMed by the keywords of duodenal trauma, therapy, diagnosis and abdomen. It shows that because the diagnosis and management are complicated and the mortality is high, duodenal trauma should be treated in time and tactfully. And application of new technology can help improve the management. In this review, we discussed the incidence, diagnosis, management, and complications as well as mortality of duodenal trauma.

Full Text Available A nine-year-old female Rottweiler with a history of repeated gastrointestinal ulcerations and three previous surgical interventions related to gastrointestinal ulceration presented with symptoms of anorexia and intermittent vomiting. Benign gastric outflow obstruction was diagnosed in the proximal duodenal area. The initial surgical plan was to perform a pylorectomy with gastroduodenostomy (Billroth I procedure, but owing to substantial scar tissue and adhesions in the area a palliative gastrojejunostomy was performed. This procedure provided a bypass for the gastric contents into the proximal jejunum via the new stoma, yet still allowed bile and pancreatic secretions to flow normally via the patent duodenum. The gastrojejunostomy technique was successful in the surgical management of this case, which involved proximal duodenal stricture in the absence of neoplasia. Regular telephonic followup over the next 12 months confirmed that the patient was doing well.

Full Text Available Background/Purpose. Kimura's diamond-shaped-duodenoduodenostomy (DSD is a known technique for the correction of congenital intrinsic duodenal obstruction. We present a modification of the technique and review the advantages of this new technique. Methods. From 1992 to 2006, 14 newborns were treated for duodenal atresia. We inverted the direction of the duodenal incisions: a longitudinal incision was made in the proximal duodenum while the distal was opened by transverse incision. Results. Our “inverted-diamond-shaped-duodenoduodenostomy” (i-DSD allowed postoperative oral feeding to start on days 2 to 3, peripheral intravenous fluids discontinuity on days 3 to 8 (median values 3.6; time to achieve full oral feeds on days 8 to 12 (median values 9.4; the length of hospitalisation ranged from 10 and 14 days (median value 11.2. No complications related to the anastomosis, by Viz leakage, dehiscence, biliary stasis, or stenosis were observed. Conclusions. The i-DSD provides a safe procedure to protect the ampulla of Vater from injury and avoids any formation of a blind loop. The results show that patients who have i-DSD achieve full oral feeds in a very short time period and, consequently, the length of hospitalisation is also significantly reduced.

Duodenal pH in health and duodenal ulcer disease: effect of a meal, Coca-Cola, smoking, and cimetidine.

Science.gov (United States)

McCloy, R F; Greenberg, G R; Baron, J H

1984-04-01

Intraluminal duodenal pH was recorded using a combined miniature electrode and logged digitally every 10 or 20 seconds for five hours (basal/meal/drink) in eight control subjects and 11 patients with duodenal ulcer (five on and off treatment with cimetidine). Over the whole test there were no significant differences in duodenal mean pH or log mean hydrogen ion activity (LMHa) between control subjects and patients with duodenal ulcer, but there were significantly longer periods of duodenal acidification (pH less than 4) and paradoxically more periods of duodenal alkalinisation (pH greater than 6) in the duodenal ulcer group compared with controls. After a meal duodenal mean pH and LMHa fell significantly in both controls and patients with duodenal ulcer, with more periods of duodenal acidification and alkalinisation in the duodenal ulcer group. An exogenous acid load (Coca-Cola) significantly increased the periods of duodenal acidification, and reduced alkalinisation, in both groups. Cimetidine significantly increased mean pH and LMHa and abolished the brief spikes of acidification in four of five patients with duodenal ulcer. Peak acid output (but not basal acid output) was significantly correlated with duodenal mean pH and LMHa but not with the periods of duodenal acidification. Smoking did not affect duodenal pH in either group.

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.

Duodenal hematomas from blunt abdominal trauma are uncommon in children and treatment strategies vary. We reviewed our experience with this injury at a large-volume children's hospital. A retrospective case series was assembled from January 2003-July 2014. Data collected included demographics, clinical and radiographic characteristics, and hospital course. Patients with grade I injuries based on the American Association for the Surgery of Trauma Duodenum Injury Scale were compared with those with grade II injuries. Nineteen patients met inclusion criteria at a median age of 8.91 y (range, 1.7-17.2 y). Mechanisms of injury included direct abdominal blow or handle bar injury (n = 9), nonaccidental trauma (n = 5), falls (n = 3), and motor vehicle accident (n = 2). Ten patients had grade I hematomas and nine had grade II. Hematomas were most frequently seen in the second portion of the duodenum (n = 9). Five patients underwent a laparotomy for concerns for hollow viscus injury. No patients required operative drainage of the hematoma; however, one patient underwent percutaneous drainage. Twelve patients received parenteral nutrition (PN) for a median duration of 9 d (range, 5-14 d). Median duration of PN for grade I was 6.5 d (range, 5-8 d) versus 12 d for grade II (range, 9-14 d; P = 0.016). Complications included one readmission for concern of bowel obstruction requiring bowel rest. This study suggests that duodenal hematomas can be successfully managed nonoperatively. Grade II hematomas are associated with longer duration of PN therapy and consequently longer hospital stays. These data can assist in care management planning and parental counseling for patients with traumatic duodenal hematomas. Copyright © 2015 Elsevier Inc. All rights reserved.

2001-01-01

Purpose: To assess the efficacy of self-expanding metallic stents in treating inoperable gastric and duodenal stenoses during follow-up and to evaluate the complications encountered.Methods: A total of 31 patients suffering from gastroduodenal obstruction (29 malignant, 2 benign) were treated with a self-expanding metallic stent (Wallstent). In 24 cases insertion was by the peroral route, in seven cases via gastrostomy.Results: All the strictures were successfully negotiated under fluoroscopic guidance without having to resort to endoscopy. A total of 27 patients (87%) were able to resume a regular diet, a soft diet, or a liquid diet orally. Complications included one case of stent malpositioning, one case of leakage of ascitic fluid through the gastrostomy orifice, one case of perforation and fistula to the biliary tree, and two cases of hematemesis. In two patients (6%) additional stents were implanted to improve patency. In all patients follow-up was maintained until death. Recurrence of symptoms immediately before death occurred in seven cases (23%). Mean survival time of patients was 13.3 weeks (SE ± 4.6).Conclusions: The deployment of gastroduodenal stents resulted in good palliation of inoperable gastric and duodenal stenoses. Certain technical aspects, e.g., adaptation of stents to bowel morphology, is critical to proper stent function and avoidance of complications

Endoscopic stenting versus operative gastrojejunostomy for malignant gastric outlet obstruction.

Malignant gastric outlet obstruction represents a terminal stage in pancreatic cancer. Between 5% and 25% of patients with pancreatic cancer ultimately experience malignant gastric outlet obstruction. The aim in palliating patients with malignant gastric outlet obstruction is to reestablish an oral intake by restoring gastrointestinal continuity. This ultimately improves their quality of life in the advanced stages of cancer. The main drawback to operative bypass is the high incidence of delayed gastric emptying, particularly in this group of patients with symptomatic obstruction. This study aimed to compare surgical gastrojejunostomy and endoscopic stenting in palliation of malignant gastric outlet obstruction, acknowledging the diversity and heterogeneity of patients with this presentation. This retrospective study investigated patients treated for malignant gastric outlet obstruction from December 1998 to November 2008 at Nepean Hospital, Sydney, Australia. Endoscopic duodenal stenting was performed under fluoroscopic guidance for placement of the stent. The operative patients underwent open surgical gastrojejunostomy. The outcomes assessed included time to diet, hospital length of stay (LOS), biliary drainage procedures, morbidity, and mortality. Of the 45 participants in this study, 26 underwent duodenal stenting and 19 had operative bypass. Comparing the stenting and operative patients, the median time to fluid intake was respectively 0 vs. 7 days (P < 0.001), and the time to intake of solids was 2 vs. 9 days (P = 0.004). The median total LOS was shorter in the stenting group (11 vs. 25 days; P < 0.001), as was the median postprocedure LOS (5 vs. 10 days; P = 0.07). Endoscopic stenting is preferable to operative gastrojejunostomy in terms of shorter LOS, faster return to fluids and solids, and reduced morbidity and in-hospital mortality for patients with a limited life span.

Duodenal diverticular occur very frequently among the general public. However, duodenal diverticulitis is a very uncommon clinical entity, the diagnosis of which requires radiological studies since the clinical signs cam mimic a great number of disease processes with different treatments. We present a case of duodenal diverticulitis in which the diagnosis according to ultrasound and computed tomography (CT) studies was confirmed intraoperatively. We also review the few cases of this entity reported in the literature. The CT findings are highly suggestive of duodenal diverticulitis given their similarity to those associated with diverticulitis at other sites. (Author) 5 refs,

One hundred twenty-nine patients with far advanced or recurrent gastric carcinoma underwent computed tomography (CT) of the abdomen. There were three histologic types: differentiated (n=41), undifferentiated (n=68), and unclassified (n=20). Eighteen patients who had developed obstructive jaundice were retrospectively studied to elucidate the nature of obstruction with histologic correlation. In differentiated carcinomas tumor tended to grow in an expansive fashion. A fairly large, well-defined lymph adenopathy was observed on CT. The extrahepatic bile duct surrounded by lymph nodes appeared as ''doughnot sign'' in six of eight patients. Undifferentiated gastric carcinoma had tendency to extend infiltratively. Bile duct obstruction was only a part of diffuse spreading. In spite of the presence of obstructive jaundice, no discrete mass was demonstrated around the extrahepatic bile duct on CT. In none of nine patients was present ''doughnot sign''. The significance of lymph node dissection along the extrahepatic bile duct in patients with differentiated gastric carcinoma was emphasized. The region of hepatoduodenal and pancreatico-duodenal lymph nodes should be carefully evaluated in interpretation of abdominal CT. (author)

Diospyrobezoar as a Cause of Small Bowel Obstruction

Andréia Padilha de Toledo

2012-09-01

Full Text Available Phytobezoar, a concretion of indigestible fibers derived from ingested vegetables and fruits, is the most common type of bezoar. Diospyrobezoar is a subtype of phytobezoar formed after excessive intake of persimmons (Diospyros kaki. We report the case of a diabetic man with a 5-day history of abdominal pain after massive ingestion of persimmons who developed signs of complicated small bowel obstruction. The patient had a previous history of Billroth II hemigastrectomy associated with truncal vagotomy to treat a chronic duodenal ulcer 14 years earlier. Since intestinal obstruction was suspected, he underwent emergency laparotomy that revealed an ileal obstruction with small bowel perforation and local peritonitis due to a phytobezoar that was impacted 15 cm above the ileocecal valve. After segmental intestinal resection, the patient had a good recovery and was discharged on the 6th postoperative day. This report provides evidence that diospyrobezoar should be considered as a possible cause of small bowel obstruction in patients who have previously undergone gastric surgery.

Full Text Available Objective: Neuroendocrine tumors are neoplasms derived from endocrine cells, most commonly occurring in the gastrointestinal tract. Duodenal neuroendocrine tumors are rare tumors averaging 1.2–1.5 cm, and most are asymptomatic. Common presentation is abdominal pain, upper gastrointestinal bleed, constipation, anemia, and jaundice. Methods: An adult, Black, male patient with newly diagnosed diabetes mellitus presented to the emergency department with elevated liver function test and fatigue. Results: Magnetic resonance cholangiopancreatography demonstrated a large obstructing mass (3.6 cm × 4.4 cm × 3 cm within the second and third portions of the duodenum at the ampulla. Esophagogastroduodenoscopy demonstrated an ulcerated duodenal mass that was biopsied. Immunohistochemical stains were positive for synaptophysin, chromogranin B, and CK7. Chromogranin A was in normal range. Post-Whipple procedure demonstrated a 5.5 cm × 4.1 cm × 2.9 cm duodenal mass with invasion of the subserosal tissue of the small intestine, a mitotic rate of 2 per high-power field, and antigen Ki-67 of 2%–5%. Conclusion: This case raises the question as to if the patient developed diabetes mellitus due to the tumor size and location or if the new onset of diabetes was coincidental. This case also demonstrates the importance of a proficient history and physical.

We report a case of lipoma in the antrum of the stomach which prolapsed into the duodenal bulb and caused a duodenal ulcer, which was speculated to have been induced by the friction of its tip against the duodenal mucosa. Although the duodenal ulcer healed after the administration of a proton pump inhibitor, the symptoms of epigastric discomfort continued, which was suggested to be due to the prolapse. Therefore, a laparoscopic operation was conducted. The incidence of lipoma of the stomach is rare, and cases of its prolapse into the duodenum are few. Furthermore, it is extremely rare for it to cause a duodenal ulcer. Because these features made this case clinically interesting, we report it here.

A single center study was conducted to compare the short-term clinical outcome between laparoscopic surgery (LS) and open surgery (OS) repair for neonates with congenital duodenal obstruction (CDO). Medical records of all neonates with bodyweight at surgery over 1500g and without other gastrointestinal anomalies that underwent surgery (duodeno-duodenostomy or duodeno-jejunostomy) for CDO at our center between January 2009 and July 2015 were reviewed. The choice of OS or LS was surgeon-dependent. One hundred twelve patients were identified, with a median age and weight at surgery 8.5days and 2500g respectively. Forty-four patients underwent OS and 68 patients LS. There were no significant differences between the two groups regarding patient age, gender, weight at surgery, associated anomalies, and mean operative time. Compared to OS, the LS group had lower postoperative complications (5.9% vs 36.4%, p<0.0001), shorter mean time to initial oral feeding and mean postoperative hospital stay (3.9 vs. 7.1days and 8.6 vs. 12.9days respectively, p<0.0001) and better postoperative cosmesis. LS treatment for neonatal CDO is associated with lower postoperative morbidity, shorter recovery time and postoperative hospital stay and better postoperative cosmesis than OS.

The occurrence of dyspeptic symptoms has previously been correlated with the shape of the duodenal loop in patients with X-ray-negative dyspepsia. An abnormal duodenal loop was associated with a significantly higher incidence of symtoms provoked by meals, vomiting, regurgitations, heartburn, and the irritable bowel syndrome. 89% of these patients (26 patients with a normal duodenal loop and 39 patients with abnormal duodenal loop) were available for a 5-year follow-up study of symptomatic outcome. The incidence of symptoms provoked by meals was still significantly higher in patients with an abnormal duodenal loop, and there was also a significant difference concerning symptomatic outcome. Approximately 75% of the patients with a normal duodenal loop had improved, and 25% had unchanged clinical conditions. Approximately 50% of the patients with an abnormal duodenal loop had improved, and 50% had an unchanged or even deteriorated clinical condition

A 63-year-old woman with abdominal pain was referred to our hospital. Her pancreatic enzymes were elevated, and an abdominal computed tomography (CT) scan showed an enlarged pancreas, consistent with pancreatitis, and gas collection containing an impacted stone adjacent to Vater's papilla. This finding raised the suspicion of a duodenal diverticulum. A subsequent ERCP showed a juxtapapillary duodenal diverticulum (JPDD) filled with calculi and pus. The pancreatitis improved with 2 weeks of conservative treatment. Subsequently, the patient underwent resection of the uterus and bilateral adnexa to remove a large ovarian cyst that was also identified on the admission CT scan. On the third postoperative day, she developed abdominal pain and vomiting. CT revealed small bowel obstruction caused by an enterolith expelled from JPDD. Enterotomy was performed to remove the stone. To our knowledge, only three similar cases have been previously reported in Japan.

Full Text Available Empyema of the gallbladder develops when the gallbladder neck is obstructed in the presence of infection, preventing pus from draining via the cystic duct. Treatment options include cholecystectomy or, in patients with comorbidities, drainage via percutaneous cholecystostomy, later followed by cholecystectomy. Here, we describe a 59-year-old man who presented with complaints of recurrent hiccups and was found to have cholangiocarcinoma causing obstruction to cystic duct drainage. The patient was managed successfully by percutaneous transhepatic cholecysto-duodenal self-expandable covered metal stent.

Villous duodenal adenoma with II and III grade dysplasia and carcinoma in situ treated with cephalic duodenopancreatectomy

Full Text Available Background. Villous duodenal adenomas are rare, tend to malignant alteration and recurrence if surgical procedures are not sufficiently radical. They are mostly localized in the second portion of the duodenum and close to a papilla and are prone to malignant alteration. Case report. In this paper we presented a 79-year-old female patient already operated on twice elsewhere due to obstructive jaundice caused by villous duodenal adenoma, using, firstly, cholecystectomy and T-tube drainage of the choledoclus, and, then, an unsuccessful attempt of radical surgery − duodenopancreatectomy. The patient was some time wearing a T-tube drainage, and, then, submitted to endoscopic papillotomy, endoscopic stenting, and, finally to the insertion of a self-expandable metallic stent which got clogged three months later causing chalangitis. Three years following the first surgery, the patient presented to our institution and submitted to cephalic duodenopancreatectomy. Histology confirmed villous duodenal adenomas with II and III grade dysplasia and carcinoma in situ. The lymph nodes were tumour-free. The postoperative recovery was somewhat prolonged due to cardiologic difficulties and a mild infection of the wound. Conclusion. Villous duodenal adenoma is curable if treated correctly and in a proper time. Radical treatment delay increases the risk for malignant alteration which was the case with our patient who was submitted to it three years after the histologic confirmation of the diagnosis.

Giant duodenal ulcers

Giant duodenal ulcers (GDUs) are a subset of duodenal ulcers that have historically resulted in greater morbidity than usual duodenal ulcers. Until recently,few cases had been successfully treated with medical therapy. However, the widespread use of endoscopy,the introduction of H-2 receptor blockers and proton pump inhibitors, and the improvement in surgical techniques all have revolutionized the diagnosis,treatment and outcome of this condition. Nevertheless,GDUs are still associated with high rates of morbidity,mortality and complications. Thus, surgical evaluation of a patient with a GDU should remain an integral part of patient care. These giant variants, while usually benign, can frequently harbor malignancy. A careful review of the literature highlights the important differences when comparing GDUs to classical peptic ulcers and why they must be thought of differently than their more common counterpart.

Duodenal diverticulum is a pouch like protrusion of the mucous menibrane through a weak area or defect of the muscle layer of the duodenal wall. 206 cases of the duodenal diverticular out of the consecutive 4030 cases on upper G-I series during the period from Feb. 1977 to Aug. 1978 Department of Radiology, College of Medicine, Hanyang University were studied. The results were as follows; 1. Overall incidence of duodenal diverticular was 5.1 percent (5.0 percent in male, and 5.3 percent in female). 2. The incidence of duodenal diverticular were 1.4 percent in the age group below 19, 1.4 percent in the second decade, 0.8 percent in the third decade, 2.4 percent in the fourth decade, 5.3 percent in the fifth decade, 10.2 percent in the sixth decade, 9.2 percent in the seventh decade, and 17.0 percent in the age group over 70. Incidence of duodenal diverticular is higher in the older individuals. 3. Male was more frequently affected in the age group below 40, but more in females in the age group over 40. 4. 76.3 percent of duodenal diverticular were found in the concave side of the second portion of the duodenum. 5. Multiplicity of duodenal diverticular was 5.8 percent of cases. Triple duodenal diverticular were found in 1 case. 6. The size of duodenal diverticular was variable from 3 to 70 mm in diameter. More than half of duodenal diverticular were smaller than 9 mm in diameter. Large diverticular of more than 30 mm in diameter were 13.6 percent of cases. The size of the duodenal diverticular were relatively large in older age group.

281 cases of neonatal and infantile intestinal obstruction confirmed by clinical and surgical procedure from 1975 till 1979 were reviewed radiologically. The result was as follows; 1. Intussusception was the most common cause of intestinal obstruction under one year of age (173/281: 61.56%), and other causes of descending order were infantile hypertrophic pyloric stenosis (20: 7.11%), congenital megacolon (19: 6.76%), anorectal malformation (17: 6.05%), meconium plug syndrome (17: 6.05%), hernia (12: 4.27%), band adhesion (8: 2.85%), rotation anomaly (5: 1.78%), small bowel atresia (3: 1.07%), Meckel's diverticulum (3: 1.07%), duodenal atresia (2: 0.71%), meconium ileus (1: 0.36%) and annular pancreas (1: 0.36%). Congenital type of intestinal obstruction (we classified intussusception acquired and others congenital) occupied 38.44%. 2. The ratio of male to female was 3: 1, congenital type 4.69 : 1 and acquired 2.39 : 1. 3. Vomiting, bloody stool, fever and abdominal distention were the most 4 symptoms. 4. The frequency of typical mechanical ileus pattern on plain abdomen films was 226 cases(80.43%) paralytic ileus or normal finding was 52 cases (18.51%) and pneumoperitoneum with ileus sign was 3 cases (1.06%). 5. Barium meal or enema was performed in 228 cases and narrowing or obstructed site was found in 213 cases of them (93.42%); intussusception 100% (173/173), infantile hypertrophic pyloric stenosis 93.33% (14/15) and congenital megacolon 82.35% (14/17). 6. Only 10 cases had associated disease such as Mongolism, thoracic kyphosis and scoliosis, microcolon, prematurity, ileocolic fistula, undescended testicle and hydrocele. 7. Meconium plug syndrome, duodenal atresia, small bowel atresia, mecondium ileus and annular pancreas were developed early after birth with average onset age of 3.6 days.

Post-gastrectomy anastomosis site obstruction is a relatively rare complication after a subtotal gastrectomy. We present a case of a 75-year-old man who underwent a truncal vagotomy, omental patch, gastrojejunostomy, and Braun anastomosis for duodenal ulcer perforation and a gastric outlet obstruction. Following the 10(th) postoperative day, the patient complained of abdominal discomfort and vomiting. We diagnosed post-gastrectomy anastomosis site obstruction by an upper gastrointestinal series and an upper endoscopic examination. We inserted a self-expandable metallic stent (SEMS) at the anastomosis site. The stent was fully expanded after deployment. On the day following the stent insertion, the patient began to eat, and his abdominal discomfort was resolved. This paper describes the successful management of post-gastrectomy anastomosis site obstruction with temporary placement of a SEMS.

Gastric emptying abnormal in duodenal ulcer

Energy Technology Data Exchange (ETDEWEB)

Holt, S.; Heading, R.C.; Taylor, T.V.; Forrest, J.A.; Tothill, P.

1986-07-01

To investigate the possibility that an abnormality of gastric emptying exists in duodenal ulcer and to determine if such an abnormality persists after ulcer healing, scintigraphic gastric emptying measurements were undertaken in 16 duodenal ulcer patients before, during, and after therapy with cimetidine; in 12 patients with pernicious anemia, and in 12 control subjects. No difference was detected in the rate or pattern of gastric emptying in duodenal ulcer patients before and after ulcer healing with cimetidine compared with controls, but emptying of the solid component of the test meal was more rapid during treatment with the drug. Comparison of emptying patterns obtained in duodenal ulcer subjects during and after cimetidine treatment with those obtained in pernicious anemia patients and controls revealed a similar relationship that was characterized by a tendency for reduction in the normal differentiation between the emptying of solid and liquid from the stomach. The similarity in emptying patterns in these groups of subjects suggests that gastric emptying of solids may be influenced by changes in the volume of gastric secretion. The failure to detect an abnormality of gastric emptying in duodenal ulcer subjects before and after ulcer healing calls into question the widespread belief that abnormally rapid gastric emptying is a feature with pathogenetic significance in duodenal ulcer disease.

Intestinal permeability (IP) to 51 Cr ethylenediamine tetraacetic acid was investigated in 47 children with chronic obstructive respiratory disease (CORD). Endoscopic duodenal biopsies were performed in 22 of these patients. IP was significantly increased in CORD patients when compared to either control children or adults (P less than 0.001). Mean +/- 1 SD were 4.3 +/- 1.71%, 2.5 +/- 0.78%, and 2.3 +/- 0.77% in the three groups, respectively. IP was not related to the presence of atopy. Significant differences in IP results were found between CORD children with abdominal pain (4.5 +/- 1.4%) and both control children and CORD patients without abdominal pain (2.5 +/- 0.78% and 3.2 +/- 1.49%, respectively). A significant correlation was found between small bowel injury on the one hand and IP on the other hand (P less than 0.02). Furthermore, small bowel injury was significantly related to the presence of abdominal pain (P less than 0.05). We speculate that in CORD patients with abdominal pain, a factor exists that causes small bowel injury responsible for both abdominal pain and increased small bowel permeability. Food intolerance could, presumably, play a role in the mucosal damage-linked IP increase found in the subset of CORD patients who complain of abdominal pain

The causes of obstruction are diverse with varied embryological origins, and some underlying etiologies are not yet well described. Some findings of neonatal bowel obstruction can be detected prenatally on ultrasound imaging. The obstruction is classified as “high” when the level of obstruction is proximal to the ileum, and “low” when the level of obstruction is at the ileum or colon. Early diagnosis of the type of intestinal obstruction and localization of the obstructive bowel segment guides timely and appropriate management of the underlying pathologic entity. Neonatal bowel obstructions are ideally managed at specialized centers with a large volume of neonatal surgery and dedicated pediatric surgical and anesthesia expertise. Although surgical intervention is necessary in most cases, initial management strategies often target underlying metabolic, cardiac, or respiratory abnormalities. Imaging plays a key role in early and accurate diagnosis of the abnormalities. When bowel obstruction is suspected clinically, initial imaging workup usually involves abdominal radiography, which may direct further evaluation with fluoroscopic examination such as upper gastrointestinal (UGI contrast study or contrast enema. This article provides a comprehensive review of clinical and radiological features of common and less common causes of intestinal obstruction in the neonatal age group, including esophageal atresia, enteric duplication cysts, gastric volvulus, congenital microgastria, hypertrophic pyloric stenosis, duodenal atresia

Full Text Available BACKGROUND The duodenal injury can pose a formidable challenge to the surgeon and failure to manage it properly may have devastating results. Over the centuries, there was little to offer the patient of acute abdomen beyond cupping, purgation and enemas, all of which did more harm than good. It was not until 1884 that Mikulicz made an attempt to repair a perforation. Recent statistics indicate roughly 10% of population develop gastric or duodenal ulcer in life time. Roughly 1-3% of population above the age of 20 years have some degree of peptic ulcer activity during any annual period. A detailed history with regards to the signs and symptoms of the patient, a meticulous examination, radiological and biochemical investigations help to arrive at a correct preoperative diagnosis. In this study, a sincere effort has been put to understand the demographic patterns, to understand the underlying aetiology and to understand the effectiveness of the standard methods of investigation and treatment in use today. METHODS This is a 24 months prospective study i.e., from September 2011 to September 2013 carried out at Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation. The study included the patients presenting to Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation to emergency ward with signs and symptoms of hollow viscus perforation. The sample size included 30 cases of duodenal perforation. RESULTS Duodenal ulcer perforation commonly occurs in the age group of 30-60 years, but it can occur in any age group. Majority of the patients were male. Smoking and alcohol consumption were risk factors in most cases (53.3% for the causation of duodenal ulcer perforation. Sudden onset of abdominal pain, situated at epigastrium and right hypochondrium was a constant symptom (100%. Vomiting, constipation and fever were not so common.

PTC is the single most valuable diagnostic method available to evaluate the size, shape and site of the causes of obstructive jaundice among various radiological procedures. The authors reviewed and radiologically classified the PTC films of 203 cases of obstructive jaundice from July, 1977 to June, 1983 at Presbyterian Medical Center, Jeonju confirmed clinically, operatively and pathologically. The results are as follows; 1. The most common cause of obstructive jaundice was bile duct stone (64/203: 31.53%) and the other causes were bile duct cancer (43/203: 21.18%), pancreas cancer (41/203: 20.19%), biliary ascariasis and/or clonorchiasis (20/203: 9.8%), ampulla and duodenal cancer (7/203: 3.45%), fibrotic stenosis of sphincter of Oddi (6/203: 2.96%) etc. in the order. Of these primary involvement with cancer was more frequent (91/203: 44.33%) than stone. 3. The average maximal diameter of extrahepatic bile duct just proximal to the site of obstruction or stenosis by stones or by cancers was nearly equal (2.36 cm : 2.38 cm). 4. Cancers caused complete bile duct obstruction in about 75% (68/91) of cases and also were associated with intrahepatic duct dilatation about 92% (84/91) of cases. But in contrast biliary calculi showed good drainage of contrast medium in 75% (48/64) of cases and 92% (59/64) showed normal diameter

Duodenal stump insufficiency after surgery for penetrating gastroduodenal ulcer is associated with substantial mortality. "Classical" technique of closing a difficult duodenal stump (Nissen-Bsteh) has, up to now, not been compared with duodenojejunostomy (DJ) in larger patient sets. This also refers to the potential benefit of a gastric and biliary diversion under such conditions. The aim of the present study was to compare classical duodenal closure (CC) with DJ and to evaluate the impact of gastric and biliary diversion on postoperative outcome after surgery for penetrating, high-risk duodenal ulcer in a matched control study. Out of 321 patients, treated for penetrating duodenal ulcer disease, the perioperative outcome of 62 DJ patients was compared with 62 patients undergoing CC matched for age, gender, biliary diversion, and the operating surgeon collective. A total of 70 patients, equally distributed between DJ and CC subsets, received temporary biliary diversion. Overall perioperative mortality was 10.5%. However, DJ significantly reduced the mortality rate (4.8%) associated with penetrating duodenal ulcer compared to CC (16.1%, P management of penetrating duodenal ulcer.

Changes in gastroduodenal blood flow have been implicated in the pathogenesis of duodenal ulcer. The authors have studied duodenal blood flow during the development of an acute to chronic duodenal ulcer by using the abscopal model, in which ulcers are generated as an indirect effect of lower mediastinal irradiation. Female CFLP mice were randomly allocated to one of three groups. Irradiated ``controls`` received 18 Gy 250 kV X-rays to the upper mediastinum. The lower mediastinum group received the same dose of irradiation, which has been shown to induce typical chronic duodenal ulcers in 45% of animals so treated. Animals were studied by means of radiolabelled microspheres 3 or 7 days later. Proximal duodenal blood flow specifically was reduced by 32% in the lower mediastinum group compared with irradiated controls at 7 days. There was no significant difference in blood flow to the stomach and to the distal duodenum. The decrease in proximal duodenal blood flow in the lower mediastinum group did not differ in the five animals that developed ulcer compared with the seven that did not. Although, there is an overall decrease in duodenal blood flow associated with chronic duodenal ulcer, reduced blood flow may not explain individual susceptibility to ulceration. 21 refs., 1 fig., 2 tabs.

To evaluate the usefulness of CT for the diagnosis of the cause and localization of small bowel obstruction. Out of a group of children who underwent a CT examination for a suspected small bowel obstruction, 19 patients with confirmed underlying disorders were identified and included in the study. Neonates and patients with duodenal obstruction were excluded from the study. The CT findings were analyzed for the location of obstruction site, abnormalities of the mesentery and mesenteric vessels, bowel wall thickening, closed loop obstruction, and strangulation. The obstruction site was divided into five parts. The preoperative CT diagnosis was compared with the final diagnosis. Causes of small bowel obstruction were intussusception (n = 6), appendiceal perforation (n = 4), transmesenteric internal hernia (n = 2), postoperative bands (n = 1), idiopathic multiple bands (n = 1), a foreign body (n = 1), a small bowel adenocarcinoma (n = 1), Meckel's diverticulitis (n = 1), tuberculous peritonitis (n = 1) and Salmonella enteritis with bowel perforation (n = 1). The CT findings showed mesenteric vascular prominence (n = 13), omental or mesenteric infiltration (n = 10), localized bowel wall thickening (n = 7) closed loops obstruction (n = 3) and strangulation (n = 1). The obstruction site was identified in all cases. The causes of obstruction could be diagnosed preoperatively in 14 cases, but a preoperative diagnosis was difficult in 5 cases. The causes of small bowel obstruction in children are variable, and CT is useful for evaluating the cause and localization of small bowel obstruction

Full Text Available Scrub typhus is an acute febrile illness usually presenting with fever, myalgia, headache, and a pathognomonic eschar. Severe infection may lead to multiple organ failure and death. Gastrointestinal tract involvement in the form of gastric mucosal erosions and ulcerations owing to vasculitis resulting in gastrointestinal bleeding is common. This process may worsen a pre-existent asymptomatic peptic ulcer, causing duodenal perforation, and present as an acute abdomen requiring surgical exploration. We report the case of a patient with no previous symptoms or risk factors for a duodenal ulcer, who presented with an acute duodenal perforation, probably precipitated by scrub typhus infection.

To observe the relatively specific effect of electroacupuncture (EA) of "Xiajuxu" (ST 39, the lower hesea paint of the small intestine), etc. on the level of serum TNF-alpha, lnterleukin-1 P (IL-1 P) and high mobility group protein B 1 (HMGB 1) contents, and duodenum a7 nicotinic acetyicholine receptor (nAchR) expression in duodenal ulcer rats, so as to explore its mechanisms underlying improving duodenal ulcer. Sixty SD rats were randomly divided into 6 groups: normal control, model, Xiajuxu (ST 39), Zusanli (ST 36), Shangjuxu (ST 37) and Yanglingquan (GB 34). The duodenal ulcer model was established by subcutaneous injection of 10% Cysteamine Hydrochloride (300 mg/kg), following by giving the rats with access to water containing Cysteamine. EA (10 Hz/50 Hz, 1- 3 mA) was applied to bilateral ST 39, ST 36, ST 37 and GB 34 for 30 min, once daily for 10 days. The ulcer scores (0-5 points) of the duodenal mucosa were assessed according to modified Moraes' methods. Serum TNF-alpha, IL-1 beta and HMGB 1 levels were assayed by ELISA and the expression of neuronal a7 nAchR in the duodenal tissue was detected by Western blot. After modeling, the ulcer score, serum TNF-alpha, IL-i p and HMGB 1 contents were significantly increased (P0.05). EA stimulation of ST 36, ST 37 and ST 39 can reduce ulcer injury in duodenal ulcer model rats, which may be associated with their effects in down-regulating serum TNF-alpha, IL-1 beta and HMGB 1 contents and up-regulating alpha7 nAchR expression of the duodenal tissue, possibly by suppressing immune and inflammatory reactions and regulating nicotinic activity.

2018-05-01

Full Text Available Objective: Several studies have been performed concerning pathologies of the stomach and esophagus in the pediatric age group. However, there have been very few studies of duodenal pathologies in children. The authors aimed to examine the clinical, endoscopic, and histopathological characteristics, as well as the etiology of duodenal pathologies in children. Method: Patients aged between 1 and 17 years undergoing esophagogastroduodenoscopy during two years at this unit, were investigated retrospectively. Demographic, clinical, endoscopic data, and the presence of duodenal pathologies, gastritis, and esophagitis were recorded in all of the children. Results: Out of 747 children who underwent endoscopy, duodenal pathology was observed in 226 (30.3% patients. Pathology was also present in the esophagus in 31.6% of patients and in the stomach in 58.4%. The level of chronic diarrhea was higher in patients with duodenal pathology when compared with those without duodenal pathology (p = 0.002, OR: 3.91, 95% CI: 1.59–9.57. Helicobacter pylori infection was more common in patients with pathology in the duodenum (59.3%. Conclusion: Duodenal pathology was detected in 30.3% of the present patients. A significantly higher level of chronic diarrhea was observed in subjects with duodenal pathologies compared to those with no such pathology. The rate of Helicobacter pylori infection was considerably higher than that in previous studies. In addition, there is a weak correlation between endoscopic appearance and histology of duodenitis. Resumo: Objetivo: Foram feitos vários estudos com relação a patologias do estômago e esôfago na faixa etária pediátrica. Contudo, poucos estudos das patologias duodenais em crianças.

Full Text Available Duodenal white spots are mentioned in these nonspecific lesions until recently. Although there is not enough studies about duedonal white spots yet; these lesions described in a separate syndrome. Here now we reported a case that we diagnosed multiple Duodenal white spots mimicking intestinal candidiasis. Clinical manifestation and endoscopic appearance of lesions gave rise to thought intestinal candidiasis histopathological examination revealed us several duodenitis. There was no evidence of fungal infection in PAS staining. Early after endoscopy patient took treatment of Lansoprozole at the 30 mg dose and bismuth salicylate. Patients compliant declined and control endoscopy exposed white duodenal spots cleared away three months later. Duodenal white spots are becoming to be designated as a separate disease even a syndrome. Etiology of duodenal white spots must be determined carefully during endoscopy. Sometimes it is difficult to make the correct diagnosis by appearance of lesion; in such cases histopathological examination can be useful both differential diagnosis of disease and determination of etiological factor.

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)

Early Rupture of an Ultralow Duodenal Stump after Extended Surgery for Gastric Cancer with Duodenal Invasion Managed by Tube Duodenostomy and Cholangiostomy

Konstantinos Blouhos

2013-01-01

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.

Diagnosis of duodenal and pancreatic injuries is frequently delayed, and optimal treatment is often controversial. Fourteen children with duodenal and/or pancreatic injuries secondary to blunt trauma were treated between 1980 and 1997. The pancreas was injured in all but 1 child. An associated duodenal injury was present in 4. The preoperative diagnosis was suspected in only 6 patients based on clinical signs and ultrasonography. One patient was treated successfully conservatively; all the others required surgical management. At operation, three procedures were used: peripancreatic drainage, suture of the gland or duodenum with drainage, and primary distal pancreatic resection without splenectomy. A duodenal resection with reconstruction by duodeno-duodenostomy was performed in 1 case. The overall complication rate was 14%: 1 fistula and 1 pseudocyst. Pancreatic ductal transection was recognized 3 days after the initial laparotomy by endoscopic retrograde cholangiopancreatography (ERCP). The mortality was 7%; 1 patient died from septic and neurologic complications. When the diagnosis of pancreatic ductal injuries is a major problem, ERCP may be a useful diagnostic procedure. Pancreatic injuries without a transected duct may often be treated conservatively. The surgical or conservative management of duodenal hematomas is still controversial; other duodenal injuries often need surgical treatment.

Duodenal perforation in childhood is a rare condition with a high mortality rate if not treated surgically. Primary gastroduodenal perforation is frequently associated with peptic ulcer and exhibits a positive family history. Helicobacter pylorus is the most significant agent. Secondary gastroduodenal perforation may be a finding of specific diseases, such as Crohn disease, or more rarely may be associated with diseases such as cystic fibrosis or sickle cell anemia. A 14-year-old boy presented with abdominal and back pain. The patient was operated on for acute abdomen and diagnosed with duodenal perforation. Helicobacter pylorus was negative. There was no risk factor to account for duodenal perforation other than sickle cell anemia. Surgical intervention was successful and without significant sequelae. Duodenal perforation is a rare entity described in patients with sickle cell anemia. To our knowledge, this is the first report of duodenal perforation in a patient sickle cell anemia.

Acute Necrotizing Esophagitis Followed by Duodenal Necrosis

Acute Necrotizing Esophagitis is an uncommon pathology, characterized by endoscopic finding of diffuse black coloration in esophageal mucosa and histological presence of necrosis in patients with upper gastrointestinal bleeding. The first case of acute necrotizing esophagitis followed by duodenal necrosis, in 81 years old woman with a positive history of Type 2 Diabetes Mellitus, Hypertension, and usual intake of Nonsteroidal Anti-inflammatory drugs, is reported. Although its etiology remains unknown, the duodenal necrosis suggests that ischemia could be the main cause given that the branches off the celiac axis provide common blood supply to the distal esophageal and duodenal tissue. The massive gastroesophagic reflux and NSAID intake could be involved. PMID:27957030

2008-12-01

One of the perceived disadvantages of the biliopancreatic diversion with duodenal switch operation is diarrhea. The aim of this study was to compare the bowel habits of patients after duodenal switch operation or Roux-en-Y gastric bypass. A prospective comparative case series design was used. Forty-six patients who underwent duodenal switch (n=28) or gastric bypass (n=18) were asked to complete a daily diary for 14 days after losing least 50% of their excess body weight. Data were collected on number of bowel episodes, incontinence, urgency, stool consistency, and awakening from sleep to defecate. Background variables were recorded from the medical files. The duodenal switch group was heavier (body mass index 53.5 vs 47.0 kg/m(2), p=0.03) and older (47.5 vs 41.0 years, p=NS) than the gastric bypass group. Median time to 50% excess body weight loss was 22 months in the duodenal switch group compared to 10.0 months in the gastric bypass group (p=0.001). Patients after duodenal switch surgery reported a median of 23.5 bowel episodes over the 14-day study period compared to 16.5 in the gastric bypass group (p=NS). There was no between-group differences in any of the other bowel parameters studied. Although duodenal switch is associated with more bowel episodes than gastric bypass, the difference is not statistically significant. Bowel habits are similar in patients who achieve 50% estimated body weight loss with duodenal switch surgery or gastric bypass.

The management of large perforations of duodenal ulcers

Sharma Rajeev

2005-06-01

Full Text Available Abstract Background Duodenal ulcer perforations are a common surgical emergency, but literature is silent on the exact definition, incidence, management and complications of large perforations of duodenal ulcers. Methods The case files of 162 patients who underwent emergency laparotomy for duodenal ulcer perforations over a period of three years (2001 – 2003 were retrospectively reviewed and sorted into groups based on the size of the perforations – one group was defined as 'small 'perforations (less than 1 cm in diameter, another 'large' (when the perforation was more than 1 cm but less than 3 cms, and the third, 'giant'(when the perforation exceeded 3 cm. These groups of patients were then compared with each other in regard to the patient particulars, duration of symptoms, surgery performed and the outcome. Results A total of 40 patients were identified to have duodenal ulcer perforations more than 1 cm in size, thus accounting for nearly 25 % of all duodenal ulcer perforations operated during this period. These patients had a significantly higher incidence of leak, morbidity and mortality when compared to those with smaller perforations. Conclusion There are three distinct types of perforations of duodenal ulcers that are encountered in clinical practice. The first, are the 'small' perforations that are easy to manage and have low morbidity and mortality. The second are the 'large' perforations, that are also not uncommon, and omental patch closure gives the best results even in this subset of patients. The word 'giant' should be reserved for perforations that exceed 3 cms in diameter, and these are extremely uncommon.

Full Text Available Aims. To investigate the effect of biliary stent placement without endoscopic sphincterotomy (EST on common bile duct stones (CBDS disappearance and the contribution of preserving the duodenal papilla function to reduce recurrence of CBDS. Methods. Sixty-six patients admitted for acute obstructive cholangitis due to CBDS who underwent biliary stent placement without EST for 2 years from March 2011 were evaluated retrospectively. The second endoscopic retrograde cholangiopancreatography (ERCP was performed for treatment of CBDS 3 to 4 months after the first ERCP. We estimated the rate of stone disappearance at the time of second ERCP. Results. CBDS disappearance was observed in 32 (48.5% of 66 patients. The diameter of the bile ducts and the diameter of CBDS in patients with CBDS disappearance were significantly smaller than in those with CBDS requiring extraction (p=0.007 and p<0.001, resp.. Stone disappearance was evident when the diameter of bile ducts and that of CBDS were <10 and 7 mm, respectively (p=0.002. Conclusions. Short-term stent placement without EST eliminates CBDS while preserving duodenal papilla function and may be suitable for treating CBDS in patients with nondilated bile ducts and small CBDS.

Duodenal mucosal protein kinase C-δ regulates glucose production in rats.

2011-11-01

Activation of protein kinase C (PKC) enzymes in liver and brain alters hepatic glucose metabolism, but little is known about their role in glucose regulation in the gastrointestinal tract. We investigated whether activation of PKC-δ in the duodenum is sufficient and necessary for duodenal nutrient sensing and regulates hepatic glucose production through a neuronal network in rats. In rats, we inhibited duodenal PKC and evaluated whether nutrient-sensing mechanisms, activated by refeeding, have disruptions in glucose regulation. We then performed gain- and loss-of-function pharmacologic and molecular experiments to target duodenal PKC-δ; we evaluated the impact on glucose production regulation during the pancreatic clamping, while basal levels of insulin were maintained. PKC-δ was detected in the mucosal layer of the duodenum; intraduodenal infusion of PKC inhibitors disrupted glucose homeostasis during refeeding, indicating that duodenal activation of PKC-δ is necessary and sufficient to regulate glucose homeostasis. Intraduodenal infusion of the PKC activator 1-oleoyl-2-acetyl-sn-glycerol (OAG) specifically activated duodenal mucosal PKC-δ and a gut-brain-liver neuronal pathway to reduce glucose production. Molecular and pharmacologic inhibition of duodenal mucosal PKC-δ negated the ability of duodenal OAG and lipids to reduce glucose production. In the duodenal mucosa, PKC-δ regulates glucose homeostasis. Copyright © 2011 AGA Institute. Published by Elsevier Inc. All rights reserved.

Aim: To describe the multidetector computed tomography (MDCT) features of primary, locally recurrent, and metastatic duodenal gastrointestinal stromal tumours (GISTs). Materials and methods: In this institutional review board-approved, Health Insurance Portability and Accountability Act of 1996 (HIPAA)-compliant, retrospective study, 25 patients [13 men, 12 women; mean age 56 years (34–74 years)] with histopathologically confirmed duodenal GISTs seen at Dana Farber Cancer Institute and Brigham and Women's Hospital from December 1999 to October 2009 were identified. The MDCT of primary tumours in six patients and follow-up imaging in all the 25 patients was reviewed by two radiologists in consensus. Electronic medical records were reviewed to document the clinical characteristics and management. Results: The mean size of the primary tumour was 3.7 cm (range 2.5–5.6 cm). Three of six primary tumours were in the second and third portions of the duodenum, one in the third portion, one in the third and fourth portions, and one in the fourth portion. Three of six of the tumours were exophytic, two were both exophytic and intraluminal, and one was intramural. The tumours were well-circumscribed, round or oval masses, with few lobulations, and were either homogeneously hyper-enhancing or heterogeneously isodense at MDCT. None of the tumours had necrosis, haemorrhage, calcification, or loco regional lymphadenopathy on imaging. Sixteen of 25 (64%) patients developed metastatic disease, the most common sites being liver (14/16; 87.5%) and peritoneum (5/16; 31%). Conclusion: Duodenal GISTs are well-circumscribed, round or oval masses, and occur in the second through fourth portions of the duodenum, without lymphadenopathy or duodenal obstruction. Duodenal GISTS metastasize frequently to the liver and peritoneum

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 thickness biopsies taken during...... laparoscopic placement of a jejunostomy showed vacuolated myocytes and fibrosis predominantly in the outer third of the circular muscle layer of the duodenum, suggestive for visceral myopathy. The distribution of ICC was also strikingly abnormal: by light microscopy, ICC surrounding the myenteric plexus were...... lacking in the megaduodenum, whereas ICC were normally present in the duodenal circular muscle and in the jejunum. By electron microscopy, very few ICC were identified around the duodenal myenteric plexus. These findings suggest that abnormalities in ICC may contribute to the disturbed motility in some...

Full Text Available Children have a natural tendency to explore objects with their mouths; this can result in the swallowing of foreign objects. Most ingested foreign bodies pass uneventfully through the gastrointestinal tract.However, some foreign bodies cause obstruction or perforation of the gastrointestinal tract, requiring surgical intervention. Perforation of the gastrointestinal tract may be associated with considerable morbidity and mortality. The most common sites of intestinal foreign body perforation are the ileocecal and rectosigmoid regions. Foreign body perforation of the duodenum is relatively uncommon. We report the first Korean case of duodenal perforation by an ingested 8-cm lollipop stick. Lollipops are popular with the children and fairly accessible to them, as most parents are not aware of their potential harm. Pediatric clinicians should be aware of the risks associated with lollipop stick ingestion. Our report also describes the feasibility and safety of laparoscopic diagnosis and management of pediatric patients with peritonitis induced by the ingestion of foreign bodies.

Full Text Available Because of advances in the technology of gastrointestinal endoscopy and improvements in the quality of stents, it has become routine to place a stent as palliative therapy for malignant gastrointestinal obstruction. On the other hand, stent placement for malignant gastrointestinal hemorrhage has scarcely been reported, although it may be performed for hemorrhage of the esophageal varicose vein. We recently experienced a patient with refractory hemorrhage from an unresectable duodenal cancer who underwent placement of a self-expandable metallic stent (SEMS and thereafter had no recurrence of the hemorrhage. A 46-year-old man underwent laparotomy to radically resect a cancer in the third portion of the duodenum, which invaded widely to the superior mesenteric vein and its branches and was considered unresectable. After stomach-partitioning gastrojejunostomy was performed, chemotherapy was initiated according to the regimen of chemotherapy of far advanced gastric cancer. One year and 4 months after induction of chemotherapy, gastrointestinal hemorrhage occurred. Upper gastrointestinal endoscopy revealed the hemorrhage oozing from the duodenal cancer, and endoscopic hemostasis, such as injection of hypertonic saline epinephrine and argon plasma coagulation, was unsuccessful. Twenty days after emergence of the hemorrhage, an endoscopic covered SEMS was placed with confirmation by fluoroscopy. Immediately after placement of the stent, the tarry stool stopped and the anemia ceased to progress. The recurrence of the hemorrhage has not been confirmed without migration of the stent. SEMS is an effective hemostatic procedure for malignant refractory hemorrhage.

Full Text Available Purpose: In the search of a new material to repair duodenal wounds, a trial was conducted to assess the behavior of human amniotic membrane in the repair of the duodenal wall in rats. METHODS: Fifty Wistar rats weighing between 250 and 350g, male, were submitted to duodenotomy and randomly distributed into two groups. Group A (n=8 had no treatment and was used as the control group. In Group B (n=42 the duodenal wound was treated with a patch of human amniotic membrane. RESULTS: All animals in Group A died. In Group B no changes were observed with regards to death or the formation of duodenal fistula. All animals presented peritoneal adherences in the region on the duodenal wall repair and intestinal obstruction was observed in two animals. Healing of the duodenal wall in the region of the patch took place progressively as the post-operatory period increased, with regeneration of the mucosa and of the smooth muscle layer. CONCLUSION: From the clinical standpoint, the amniotic membrane proved to be a biological tissue which served as a temporary seal and allowed the wound to heal by second-intention, with re-establishment of the duodenal wall structure.OBJETIVO: Na busca de um novo material para o reparo dos ferimentos duodenais, foi efetuado um estudo para avaliar o comportamento da membrana amniótica humana no reparo da parede duodenal em ratos. MÉTODOS: Foram utilizados 50 ratos Wistar, com peso entre 250 e 350g, machos, distribuídos, aleatoriamente, em dois grupos. Grupo A (n=8, submetido à duodenotomia sem tratamento, utilizados como controle. Grupo B (n=42, submetido a um remendo de membrana amniótica humana para tratamento de ferimento duodenal provocado. RESULTADOS: Todos os animais do grupo A foram a óbito. No grupo B não foram observadas alterações quanto a óbito ou formação de fístula duodenal. Observaram-se em todos os animais aderências peritoneais à região do reparo da parede do duodeno e obstrução intestinal em

The number of Africans in Johannesburg presenting with duodenal ulcers has steadily increased over the past 50 years. The characteristics of 105 patients with duodenal ulcer who presented a Baragwanath Hospital were compared with those of matched and unmatched samples of patients without gastrointestinal conditions in the same hospital. Men with duodenal ulcers were found to be significantly better educated than their controls, most had been born in the town, and more of them were employed at higher, though not the highest, educational levels. These data were used to test Susser's proposition that duodenal ulcers are associated with "early urbanisation." Johannesburg blacks with duodenal ulcer did seem to fit the pattern, but the relation between stress and duodenal ulcer remains unclear. PMID:626837

To assess the current management and outcome of perforated duodenal peptic ulcer managed with open repair, a focused analysis was conducted, excluding gastric, traumatic and iatrogenic perforations. A retrospective study of a 6-year period identified 61 patients. Mean age was 59 (range 19-87) years and 33 (54%) were male. Medical history included nonsteroidal anti-inflammatory drugs in 46%, smoking in 30%, atherosclerosis in 26% and excessive alcohol use in 23%. Generalized abdominal tenderness was recorded in 64% of the cases. The mean (SD) C-reactive protein value was 100 (141) g/l and white blood cell count was 12.8 (7.9) E9/l. Plain abdominal X-ray was positive for air in 87% (41/47) and CT scan in 86% (18/21). Four patients (7%) were operated without radiological imaging. There were 31 patients (51%) with a delay of 24 h or more from the start of symptoms to surgery. The mean (SD) delay from admission to surgery was 9 (3) (range 3-12) h. The treatment consisted of open suture repair in 92%, peritoneal lavage in 92%, external drainage in 80% and nasogastric decompression in 92%. The overall hospital mortality and morbidity rates were 11 and 21%, respectively. The duodenal suture leak rate was 7% and intra-abdominal abscess rate was 2%. The majority of patients with perforated duodenal ulcer can be diagnosed with conventional clinical and radiological methods, and treated according to established surgical principles. The mortality and duodenal morbidity rates have remained unchanged for the last decade. Shortening preoperative delay could improve the prognosis.

Purpose: Improving local control is critical to improving survival and quality of life for patients with locally advanced unresectable pancreatic cancer (LAPC). However, previous attempts at radiation dose escalation have been limited by duodenal toxicity. In order to guide future studies, we analyzed the clinical and dosimetric factors associated with duodenal toxicity in patients undergoing fractionated chemoradiation for LAPC. Methods and Materials: Medical records and treatment plans of 106 patients with LAPC who were treated with chemoradiation between July 2005 and June 2010 at our institution were reviewed. All patients received neoadjuvant and concurrent chemotherapy. Seventy-eight patients were treated with conventional radiation to 50.4 Gy in 28 fractions; 28 patients received dose-escalated radiation therapy (range, 57.5-75.4 Gy in 28-39 fractions). Treatment-related toxicity was graded according to Common Terminology Criteria for Adverse Events, version 4.0. Univariate and multivariate analyses were performed to assess prognostic influence of clinical, pathologic, and treatment-related factors by using Kaplan-Meier and Cox regression methods. Results: Twenty patients had treatment-related duodenal toxicity events, such as duodenal inflammation, ulceration, and bleeding. Four patients had grade 1 events, 8 had grade 2, 6 had grade 3, 1 had grade 4, and 1 had grade 5. On univariate analysis, a toxicity grade ≥2 was associated with tumor location, low platelet count, an absolute volume (cm{sup 3}) receiving a dose of at least 55 Gy (V{sub 55} {sub Gy} > 1 cm{sup 3}), and a maximum point dose >60 Gy. Of these factors, only V{sub 55} {sub Gy} ≥1 cm{sup 3} was associated with duodenal toxicity on multivariate analysis (hazard ratio, 6.7; range, 2.0-18.8; P=.002). Conclusions: This study demonstrates that a duodenal V{sub 55} {sub Gy} >1 cm{sup 3} is an important dosimetric predictor of grade 2 or greater duodenal toxicity and establishes it as a

Rickard, Matthew J F X; Brohi, Karim; Bautz, Peter C

2005-07-01

The management of pancreatic and duodenal trauma has moved away from complex reconstructive procedures to simpler methods in keeping with the trend towards organ-specific, damage control surgery. A retrospective case note review was undertaken over a 30-month period to evaluate a simplified protocol for the management of these injuries. Of 100 consecutive patients there were 51 with pancreatic injury, 30 with a duodenal injury and 19 with combined pancreaticoduodenal trauma. Overall mortality was 18.0%, with a late mortality (after 24 h) of 9.9%. This is comparable to previous studies. Morbidity from abscesses, fistulas and anastomotic breakdown was acceptably low. The concept of staged laparotomy can be successfully applied to wounds of the pancreas and duodenum. Debridement of devitalized tissue and drainage can be employed for most cases of pancreatic trauma. Most duodenal injuries can be managed with debridement and primary repair. Temporary exclusion and reoperation should be employed for unstable patients.

Abnormal duodenal loop demonstrated by X-ray. Correlation to symptoms and prognosis of dyspepsia

1986-01-01

The occurrence of dyspeptic symptoms has previously been correlated with the shape of the duodenal loop in patients with X-ray-negative dyspepsia. An abnormal duodenal loop was associated with a significantly higher incidence of symtoms provoked by meals, vomiting, regurgitations, heartburn, and the irritable bowel syndrome. 89% of these patients (26 patients with a normal duodenal loop and 39 patients with abnormal duodenal loop) were available for a 5-year follow-up study of symptomatic outcome. The incidence of symptoms provoked by meals was still significantly higher in patients with an abnormal duodenal loop, and there was also a significant difference concerning symptomatic outcome. Approximately 75% of the patients with a normal duodenal loop had improved, and 25% had unchanged clinical conditions. Approximately 50% of the patients with an abnormal duodenal loop had improved, and 50% had an unchanged or even deteriorated clinical condition.

Pancreatic and duodenal injuries after blunt abdominal trauma are rare; however, delays in diagnosis and treatment can significantly increase morbidity and mortality. Multidetector computed tomography (CT) has a major role in early diagnosis of pancreatic and duodenal injuries. Detecting the often subtle signs of injury with whole-body CT can be difficult because this technique usually does not include a dedicated protocol for scanning the pancreas. Specific injury patterns in the pancreas and duodenum often have variable expression at early posttraumatic multidetector CT: They may be hardly visible, or there may be considerable exudate, hematomas, organ ruptures, or active bleeding. An accurate multidetector CT technique allows optimized detection of subtle abnormalities. In duodenal injuries, differentiation between a contusion of the duodenal wall or mural hematoma and a duodenal perforation is vital. In pancreatic injuries, determination of involvement of the pancreatic duct is essential. The latter conditions require immediate surgical intervention. Use of organ injury scales and a surgical classification adapted for multidetector CT enables classification of organ injuries for trauma scoring, treatment planning, and outcome control. In addition, multidetector CT reliably demonstrates potential complications of duodenal and pancreatic injuries, such as posttraumatic pancreatitis, pseudocysts, fistulas, exudates, and abscesses.

Bao Jean J

2012-04-01

Full Text Available Abstract Soft tissue sarcomas are uncommon tumors, and intraduodenal soft tissue sarcoma manifestation is even more rare. Only three cases of intraduodenal sarcomas have been reported in the literature thus far. Here, we report a case of an intraduodenal recurrence of a retroperitoneal sarcoma causing bowel obstruction. This unusual recurrence pattern likely relates to the patient’s previous resection and radiation treatment, and highlights the benefits, limitations and follow-up strategies after multimodality treatment.

Safety of repair for severe duodenal injuries.

2008-01-01

There is ongoing debate about the management of severe duodenal injuries (SDIs), and earlier studies have recommended pyloric exclusion. The objective of this study was to compare primary repair with pyloric exclusion to examine if primary repair can be safely used in SDIs. The medical records of 193 consecutive patients who were admitted between August 1992 and January 2004 with duodenal injuries were reviewed. After excluding early deaths (n = 50), low-grade duodenal injuries (n = 81), and pancreatoduodenectomies for catastrophic trauma (n = 12), a total of 50 patients with SDIs (grade III, IV, or V) were analyzed. Primary repair (PR--simple duodenorrhaphy or resection and primary anastomosis) was performed in 34 (68%) and pyloric exclusion (PE) in 16 (32%). Characteristics and outcomes of these two groups were compared. PE and PR patients were similar for age, injury severity score, abdominal abbreviated injury score, physiologic status on admission, time to operation, and most abdominal organs injured. PE patients had more pancreatic injuries (63% vs. 24%, p duodenum (79% vs. 42%, p = 0.02), and a nonsignificant trend toward more grade IV and V injuries (37% vs. 18%, p = 0.11). There was no difference in morbidity (including complications specific to the duodenal repair), mortality, and intensive care unit and hospital length of stay between the two groups. Pyloric exclusion is not necessary for all patients with SDIs, as previously suggested. Selected SDI patients can be safely managed by simple primary repair.

The purpose of this study was to describe the clinical and gross pathological findings, treatment, and outcome in three dogs receiving deracoxib that developed proximal duodenal perforation and subsequent septic peritonitis. Clinical findings were acute vomiting and anorexia following initiation of deracoxib therapy. Deracoxib dosages ranged from 2 to 3 mg/kg per os q 24 hours. In each dog, exploratory laparotomy revealed duodenal perforations approximately 1 cm orad to the major duodenal papilla. Two out of three dogs survived following exploratory laparotomy. Two of three dogs in the present case series received the approved deracoxib dosage. Dogs receiving deracoxib, even at labeled dosages, should be monitored judiciously for signs of gastrointestinal disease.

2001-03-01

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.

Effect of tyrosine administration on duodenal ulcer induced by cysteamine in the rat

International Nuclear Information System (INIS)

Oishi, T.; Szabo, S.

1987-01-01

Duodenal ulcers were produced by administering cysteamine to rats. Pretreatment with the catecholamine precursor, L-tyrosine (40 mg/100 g i.p. for 5 days), decreased the intensity of duodenal ulcers induced by cysteamine. Equimolar doses of tyrosine methyl ester (51.2 mg/100 g i.p. or s.c.) were equally effective in reducing ulcer intensity. Other amino acids (i.e., alanine, aspartic acid, glutamic acid, glycine, leucine, lysine, tryptophan and valine) did not prevent experimental duodenal ulcers. Coadministration of other large neutral amino acids (e.g., leucine and valine) that compete with tyrosine for uptake into the brain did not inhibit the effect of tyrosine on duodenal ulcers induced by cysteamine. Gastric, duodenal and brain dopamine concentrations were increased 1 hr after the injection of tyrosine methyl ester (25.6 mg/100 g s.c.). These results suggest that the effect of tyrosine on duodenal ulcer induced by cysteamine may be mediated by changes in gastrointestinal dopamine metabolism

Full Text Available Duodenal duplication cysts are rare congenital lesions. Their presentation is often non-specific and physical examination and laboratory studies usually reveal no abnormal findings. The diagnosis of duodenal duplication cysts can thus be challenging and relies on ultrasonography, barium swallow, contrast enhanced computed tomography (CT, magnetic resonance imaging (MRI, and magnetic resonance cholangiopancreatography (MRCP. The management of duodenal duplication cyst is surgical. Laparotomy is usually necessary, and complete resection is the management goal. Subtotal excision with stripping of the mucosa due to close involvement of the pancreatobiliary tree, and endoscopic resection have Duodenal duplication cysts are rare congenital lesions usually diagnosed in infancy, although they may present in adulthood. Prenatal diagnosis is difficult, and postnatal diagnosis relies on ultrasonography, barium swallow, contrast-enhanced computerized tomography, magnetic resonance imaging (MRI, and magnetic resonance cholangiopancreatography. A female newborn was diagnosed with an abdominal cyst (size around 6 ×; 5 × 4 cm at gestational age (GA 24 weeks, by regular prenatal examination. After her birth at GA 37 weeks, we performed abdominal ultrasonography and MRI, but there was no definite diagnosis. The usual management of an abdominal cyst involves resection by laparotomy (requiring a large incision or laparoscopy (requiring several small incisions. We performed an exploratory trans-umbilical minimal laparotomy excision for surgery, and the pathology revealed duodenal duplication. In our case, there was no recurrence of the cyst after 18 months follow-up, and the operation scar was almost undetectable. Trans-umbilical minimal laparotomy excision may be considered as an alternative choice for the management of abdominal and duodenal duplication cysts.

Duodenal Wedge Resection for Large Gastrointestinal Stromal Tumour Presenting with Life-Threatening Haemorrhage

2013-01-01

Full Text Available Background. Duodenal gastrointestinal stromal tumours (GISTs are an uncommon malignancy of the gastrointestinal (GI tract. We present a case of life-threatening haemorrhage caused by a large ulcerating duodenal GIST arising from the third part of the duodenum managed by a limited duodenal wedge resection. Case Presentation. A 61-year-old patient presented with acute life-threatening gastrointestinal bleeding. After oesophagogastroduodenoscopy failed to demonstrate the source of bleeding, a 5 cm ulcerating exophytic mass originating from the third part of the duodenum was identified at laparotomy. A successful limited wedge resection of the tumour mass was performed. Histopathology subsequently confirmed a duodenal GIST. The patient remained well at 12-month followup with no evidence of local recurrence or metastatic spread. Conclusion. Duodenal GISTs can present with life-threatening upper GI haemorrhage. In the context of acute haemorrhage, even relatively large duodenal GISTs can be treated by limited wedge resection. This is a preferable alternative to duodenopancreatectomy with lower morbidity and mortality but comparable oncological outcome.

Purpose: This study was designed to evaluate retrospectively the safety and efficacy of the percutaneous management of duodenal stump leakage with a Foley catheter after subtotal gastrectomy. Methods: Ten consecutive patients (M:F = 9:1, median age: 64 years) were included in this retrospective study. The duodenal stump leakages were diagnosed in all the patients within a median of 10 days (range, 6–20). At first, the patients underwent percutaneous drainage on the day of or the day after confirmation of the presence of duodenal stump leakage, and then the Foley catheters were replaced at a median of 9 days (range, 6–38) after the percutaneous drainage. Results: Foley catheters were placed successfully in the duodenal lumen of all the patients under a fluoroscopic guide. No complication was observed during and after the procedures in all the patients. All of the patients started a regular diet 1 day after the Foley catheter placement. The patients were discharged at a median of 7 days (range, 5–14) after the Foley catheter placement. The catheters were removed in an outpatient clinic 10–58 days (median, 28) after the Foley catheter placement. Conclusions: Fluoroscopy-guided percutaneous Foley catheter placement may be a safe and effective treatment option for postoperative duodenal stump leakage and may allow for shorter hospital stays, earlier oral intake, and more effective control of leakage sites

Why is the coexistence of gastric cancer and duodenal ulcer rare? Examination of factors related to both gastric cancer and duodenal ulcer.

The coexistence of gastric cancer with duodenal ulcer has been found empirically to be rare, but why it is rare is difficult to explain satisfactorily. To elucidate this question, we carried out a literature review of the subject. The frequency with which the two diseases coexist is 0.1-1.7%, and the main factor associated with both gastric cancer and duodenal ulcer is Helicobacter pylori infection. However, there are marked differences between the disorders of hyperchlorhydria in duodenal ulcer, and hypochlorhydria in gastric cancer. The most acceptable view of the reason for the difference may be that the acquisition of H. pylori infection occurs mainly in childhood, so that the time of acquisition of atrophic gastritis may be the most important, and if atrophic gastritis is not acquired early, high levels of gastric acid may occur, and consequently acute antral gastritis and duodenal ulcer may occur in youth, whereas, in elderly individuals, persistent H. pylori infections and the early appearance of atrophic gastritis may be the causes of low gastric acid, and consequently gastric cancer may occur. In patients with duodenal ulcer, factors such as nonsteroidal anti-inflammatory drugs (NSAIDs) and dupA-H. pylori strains may contribute to preventing the early acquisition of atrophic gastritis, while acid-suppressive therapy and vascular endothelial growth factor and other entities may inhibit atrophic gastritis. In contrast, in gastric cancer, factors such as excessive salt intake, acid-suppressive therapy, polymorphisms of inflammatory cytokines, and the homB-H. pylori strain may contribute to the early acquisition of atrophic gastritis, while factors such as NSAIDs; fruits and vegetables; vitamins A, C, and E; and good nutrition may inhibit it.

Acute abdomen during pregnancy is a medico-surgical emergency demanding concerted, synchronized specialties approach of obstetrician, surgeon and gastroenterologist. Duodenal perforation is one of the rarer causes of acute abdomen in pregnancy. Here, we report a case of duodenal perforation with peritonitis in third trimester of pregnancy requiring surgical management. Our aim of reporting this case is to stress the physicians to keep the differential of duodenal perforation also in mind while dealing with cases of acute abdomen in pregnancy and to proceed with multidisciplinary approach for better feto-maternal outcome.

Duodenal nodularity in children: A clinical and pathologic study of 17 cases

Full Text Available Aims: Duodenal nodularity is an uncommon endoscopic appearance of numerous visible mucosal nodules in the proximal duodenum. In this retrospective study we aimed to determine the clinical significance and histopathologic features of duodenal nodularity in children. Materials and Methods: The medical records of the patients who were defined to have duodenal nodularity by endoscopy were reviewed. Statistical Analysis Used: The data were expressed as mean ± SD and percentages (%. Results: Seventeen patients with endoscopically defined duodenal nodularity were chosen. The mean age at diagnosis was 12.1 years (range: 6-17 years, 9 males. Abdominal pain (47% was the most common clinical symptom and antral nodularity (41% was the most common endoscopic finding in children with duodenal nodularity. Histopathologic evaluation of duodenal nodules revealed chronic inflammation in all patients, increased intercryptal and intraepithelial numbers of eosinophils in 70.5%, and villous atrophy in 47% of patients. Giardia infestation was demonstrated in 6 patients by histologic examination and/or Giardia lamblia-specific antigen positivity in stools. The clinical diagnoses of the patients have shown variations, such as celiac disease, giardiasis, secretory IgA deficiency, and Helicobacter pylori gastritis, and some of them were associated with the others. Conclusions: Although the endoscopic appearance is similar, clinical spectrum and pathologic features are not so similar and there are no specific histomorphologic findings for nodularity. The most demonstrative findings we observed in children were increased lymphocyte and/or eosinophil infiltration in the duodenal mucosa. We suggested that care should be taken in the evaluation of microbiological and immunologic etiologies causing this prominent inflammatory reaction.

Endoscopic resection of duodenal non-lifting adenomas and subepithelial tumors is challenging and harbors a significant risk of adverse events. We report on a novel technique for duodenal endoscopic full-thickness resection (EFTR) by using an over-the-scope device. Data of 4 consecutive patients who underwent duodenal EFTR were analyzed retrospectively. Main outcome measures were technical success, R0 resection, histologic confirmation of full-thickness resection, and adverse events. Resections were done with a novel, over-the-scope device (full-thickness resection device, FTRD). Four patients (median age 60 years) with non-lifting adenomas (2 patients) or subepithelial tumors (2 patients) underwent EFTR in the duodenum. All lesions could be resected successfully. Mean procedure time was 67.5 minutes (range 50-85 minutes). Minor bleeding was observed in 2 cases; blood transfusions were not required. There was no immediate or delayed perforation. Mean diameter of the resection specimen was 28.3 mm (range 22-40 mm). Histology confirmed complete (R0) full-thickness resection in 3 of 4 cases. To date, 2-month endoscopic follow-up has been obtained in 3 patients. In all cases, the over-the-scope clip was still in place and could be removed without adverse events; recurrences were not observed. EFTR in the duodenum with the FTRD is a promising technique that has the potential to spare surgical resections. Modifications of the device should be made to facilitate introduction by mouth. Prospective studies are needed to further evaluate efficacy and safety for duodenal resections. Copyright © 2015 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

Perforated Duodenal Ulcer in a Young Child: An Uncommon Condition

Directory of Open Access Journals (Sweden)

Rohit Prasad Yadav

2009-04-01

Full Text Available Duodenal ulcer is an uncommonly diagnosed entity in children. H. pyloriinfection, blood group ‘O’ or secondary to medications like non steroidal anti-infl ammatory drugs (NSAID and corticosteroids or physiological stress in burns, head injury and mucosal ischemia are implicated as risk factors for their causation. The diagnosis is usually overlooked because of vague and variable symptoms and remote index of suspicion accounted for their low incidence in children. Undiagnosed or mistreated perforations may carry high morbidity and mortality. We report a successfully treated 41/2 year old male child who presented with features of perforation peritonitis and was incidentally found to have a perforated duodenal ulcer.

The intestinal barrier is made up of epithelial cells and intercellular junctional complexes to regulate epithelial ion transport and permeability. Dopamine (DA) is able to promote duodenal epithelial ion transport through D1-like receptors, which includes subtypes of D 1 (D 1 R) and D 5 (D 5 R), but whether D1-like receptors influence the duodenal permeability is unclear. FITC-dextran permeability, short-circuit current (I SC ), Western blot, immunohistochemistry and ELISA were used in human D 5 R transgenic mice and hyperendogenous enteric DA (HEnD) rats in this study. Dopamine induced a downward deflection in I SC and an increase in FITC-dextran permeability of control rat duodenum, which were inhibited by the D1-like receptor antagonist, SCH-23390. However, DA decreased duodenal transepithelial resistance (TER), an effect also reversed by SCH-23390. A strong immunofluorescence signal for D 5 R, but not D 1 R, was observed in the duodenum of control rat. In human D 5 R knock-in transgenic mice, duodenal mucosa displayed an increased basal I SC with high FITC-dextran permeability and decreased TER with a lowered expression of tight junction proteins, suggesting attenuated duodenal barrier function in these transgenic mice. D 5 R knock-down transgenic mice manifested a decreased basal I SC with lowered FITC-dextran permeability. Moreover, an increased FITC-dextran permeability combined with decreased TER and tight junction protein expression in duodenal mucosa were also observed in HEnD rats. This study demonstrates, for the first time, that DA enhances duodenal permeability of control rat via D 5 R, which provides new experimental and theoretical evidence for the influence of DA on duodenal epithelial barrier function. © 2016 Scandinavian Physiological Society.

this incidental finding is explained by more potent gastric acid inhibition by omeprazole or might be caused by the different mode of drug action. Basal and stimulated gastric and duodenal bicarbonate secretion rates were measured in the same subjects in control experiments (n=17) and after pretreatment with high......H 6.9 v 6.8; p>0.05). Omeprazole caused higher rates of basal (mean (SEM)) (597 (48) v 351 (39) mu mol/h; pstimulated (834 (72) v 474 (66) mu mol/h; pstimulated (3351 (678) v 2550 (456) mu mol/h; p>0.05) duodenal bicarbonate secretion compared with control...... experiments. Also the combination of omeprazole and ranitidine increased (p=0.05) duodenal bicarbonate secretion, while ranitidine alone caused no change in either basal or stimulated secretion. In the stomach basal as well as vagally stimulated bicarbonate secretion was independent of the means of acid...

An Option of Conservative Management of a Duodenal Injury Following Laparoscopic Cholecystectomy

MA Modi

2014-01-01

Full Text Available Duodenal injury following laparoscopic cholecystectomy is rare complications with catastrophic sequelae. Most injuries are attributed to thermal burns with electrocautery following adhesiolysis and have a delayed presentation requiring surgical intervention. We present a case of a 47-year-old gentleman operated on for laparoscopic cholecystectomy with a bilious drain postoperatively; for which an ERC was done showing choledocholithiasis with cystic duct stump blow-out and a drain in the duodenum suggestive of an iatrogenic duodenal injury. He was managed conservatively like a duodenal fistula and recovered without undergoing any intervention.

Changing trend in emergency surgery for perforated duodenal ulcer

International Nuclear Information System (INIS)

Gurteyik, E.

2003-01-01

Objective: To evaluate changes in the emergency surgery of the duodenal ulcer. Subjects and Methods: Hospital records of 523 surgically treated patients, with duodenal ulcer perforation, during the period of 25 years 91975-1999) in the same surgical department, was retrospectively analysed. Changing aspects of emergency surgery of peptic ulcer disease, in the recent period, were determined in respect to number of operations per year and in the choice of operative methods. Results: The average number of patients and emergency operations per year was 21. No significant change was observed during the study period. Elective operations gradually decreased in the last ten years, and none was performed in the last 4 years. On the other hand, 226 emergency interventions for duodenal ulcer perforation were performed in the last ten years and 84 interventions in the last 4 years. Definitive anti-ulcer surgery was performed in 42% of patients between 1985 and 1994. Simple closure of the perforation plus treatment with proton pump inhibitors and with anti-Helicobacter pylori medication was the method in 80% during the last year. Conclusion: Emergency surgery for perforated duodenal ulcer preserves its steady rate despite disappearance of elective operations after tremendous progress in medical control of peptic ulcer disease. There is an obvious return from definitive anti-ulcer surgery to simple closure of the perforation followed by antisecretory and antibacterial medications in the recent years. (author)

Common Bile Duct Obstruction Secondary to a Periampullary Diverticulum

Directory of Open Access Journals (Sweden)

Anastasios J. Karayiannakis

2012-07-01

Full Text Available Periampullary duodenal diverticula are not uncommon and are usually asymptomatic although complications may occasionally occur. Here, we report the case of a 72-year-old woman who presented with painless obstructive jaundice. Laboratory tests showed abnormally elevated serum concentrations of total and direct bilirubin, of alkaline phosphatase, of γ-glutamyl transpeptidase, and of aspartate and alanine aminotransferases. Serum concentrations of the tumor markers carbohydrate antigen 19-9 and carcinoembryonic antigen were normal. Abdominal ultrasonography showed dilatation of the common bile duct (CBD, but no gallstones were found either in the gallbladder or in the CBD. The gallbladder wall was normal. Computed tomography failed to detect the cause of CBD obstruction. Magnetic resonance imaging and magnetic resonance cholangiopancreatography revealed a periampullary diverticulum measuring 2 cm in diameter and compressing the CBD. The pancreatic duct was normal. Hypotonic duodenography demonstrated a periampullary diverticulum with a filling defect corresponding to the papilla. CBD compression by the diverticulum was considered as the cause of jaundice. The patient was successfully treated by surgical excision of the diverticulum. In conclusion, the presence of a periampullary diverticulum should be considered in elderly patients presenting with obstructive jaundice in the absence of CBD gallstones or of a tumor mass. Non-interventional imaging studies should be preferred for diagnosis of this condition, and surgical or endoscopic interventions should be used judiciously for the effective and safe treatment of these patients.

CpG island methylator phenotype (CIMP) has been found in multiple precancerous and cancerous lesions, including colorectal adenomas, colorectal cancers, and duodenal adenocarcinomas. There are no reports in the literature of a relationship between CIMP status and clinicopathologic features of sporadic duodenal adenomas. This study sought to elucidate the role of methylation in duodenal adenomas and correlate it with KRAS and BRAF mutations. CIMP+ (with more than 2 markers methylated) was seen in 33.3% of duodenal adenomas; 61% of these CIMP+ adenomas were CIMP-high (with more than 3 markers methylated). Furthermore, CIMP+ status significantly correlated with older age of patients, larger size and villous type of tumor, coexistent dysplasia and periampullary location. MLH1 methylation was seen in 11.1% of duodenal adenomas and was significantly associated with CIMP+ tumors, while p16 methylation was an infrequent event. KRAS mutations were frequent and seen in 26.3% of adenomas; however, no BRAF mutations were detected. Furthermore, CIMP-high status was associated with larger size and villous type of tumor and race (non-white). These results suggest that CIMP+ duodenal adenomas may have a higher risk for developing malignancy and may require more aggressive management and surveillance.

Acute mesenteric ischemia and duodenal ulcer perforation: a unique double pathology

Directory of Open Access Journals (Sweden)

Haruna Lois

2012-10-01

Full Text Available Abstract Background Acute mesenteric ischaemia and duodenal perforation are surgical emergencies with serious consequences. Patients presenting with acute mesenteric ischaemia alone face a high mortality rate as high as 60% whereas those presenting with peptic ulcer perforation the mortality rates range from 6-14%. There are very few reported cases of patients presenting with this dual pathology. Case presentation We report a unique case of a 53 year old Italian lady who presented with acute mesenteric ischaemia and duodenal perforation. This is the first report of massive bowel ischaemia and duodenal perforation with no apparent underlying common pathophysiology leading to this presentation. Conclusion Early management in the intensive care unit and appropriate surgical intervention maximised the patient’s chances of survival despite the poor prognosis associated with her dual pathology. The rare pathology of the patient described can be explained by two possible hypotheses: peptic ulcer disease causing duodenal ulceration, which precipitated ischaemic infarction of the small bowel. The second hypothesis is the patient developed a stress related ulcer following ischaemic bowel infarction secondary to arterial thrombosis.

The duodenum senses nutrients to maintain energy and glucose homeostasis, but little is known about the signaling and neuronal mechanisms involved. We tested whether duodenal activation of adenosine 3',5'-cyclic monophosphate (cAMP)-dependent protein kinase A (PKA) is sufficient and necessary for cholecystokinin (CCK) signaling to trigger vagal afferent firing and regulate glucose production. In rats, we selectively activated duodenal PKA and evaluated changes in glucose kinetics during the pancreatic (basal insulin) pancreatic clamps and vagal afferent firing. The requirement of duodenal PKA signaling in glucose regulation was evaluated by inhibiting duodenal activation of PKA in the presence of infusion of the intraduodenal PKA agonist (Sp-cAMPS) or CCK1 receptor agonist (CCK-8). We also assessed the involvement of a neuronal network and the metabolic impact of duodenal PKA activation in rats placed on high-fat diets. Intraduodenal infusion of Sp-cAMPS activated duodenal PKA and lowered glucose production, in association with increased vagal afferent firing in control rats. The metabolic and neuronal effects of duodenal Sp-cAMPS were negated by coinfusion with either the PKA inhibitor H89 or Rp-CAMPS. The metabolic effect was also negated by coinfusion with tetracaine, molecular and pharmacologic inhibition of NR1-containing N-methyl-d-aspartate (NMDA) receptors within the dorsal vagal complex, or hepatic vagotomy in rats. Inhibition of duodenal PKA blocked the ability of duodenal CCK-8 to reduce glucose production in control rats, whereas duodenal Sp-cAMPS bypassed duodenal CCK resistance and activated duodenal PKA and lowered glucose production in rats on high-fat diets. We identified a neural glucoregulatory function of duodenal PKA signaling. Copyright © 2012 AGA Institute. Published by Elsevier Inc. All rights reserved.

The diagnosis of intestinal lymphangiectasia (IL) has been associated with characteristic duodenal mucosal changes. However, the sensitivity and specificity of the endoscopic duodenal mucosal appearance for the diagnosis of IL are not reported. To evaluate the utility of endoscopic images of the duodenum for diagnosis of IL. Endoscopic appearance of the duodenal mucosal might predict histopathologic diagnosis of IL with a high degree of sensitivity and specificity. 51 dogs that underwent upper gastrointestinal (GI) endoscopy and endoscopic biopsies. Retrospective review of images acquired during endoscopy. Dogs were included if adequate biopsies were obtained during upper GI endoscopy and digital images were saved during the procedure. Images were assessed for the presence and severity of IL. Using histopathology as the gold standard, the sensitivity and specificity of endoscopy for diagnosing IL were calculated. Intestinal lymphangiectasia (IL) was diagnosed in 25/51 dogs. Gross endoscopic appearance of the duodenal mucosa had a sensitivity and specificity (95% confidence interval) of 68% (46%, 84%) and 42% (24%, 63%), respectively for diagnosis of IL. Endoscopic images in cases with lymphopenia, hypocholesterolemia, and hypoalbuminemia had a sensitivity of 80%. Endoscopic duodenal mucosa appearance alone lacks specificity and has only a moderate sensitivity for diagnosis of IL. Evaluation of biomarkers associated with PLE improved the sensitivity; however, poor specificity for diagnosis of IL supports the need for histopathologic confirmation.

Mcfarlane, Michael; Liu, B; Nwokolo, C

2018-04-01

Domperidone is thought to accelerate gastric emptying via D2 receptor antagonism at the gastro-oesophageal and gastro-duodenal junctions. Listed in the BNF as a prokinetic anti-emetic, it has been used in video capsule endoscopy (VCE) to accelerate capsule delivery to the small intestine. We audited VCEs performed at UHCW from 2011, when as standard practice, domperidone was given pre-VCE, to 2012, after its discontinuation due to doubts about its effectiveness. Thirty-one patients received oral domperidone 20 mg pre-VCE. Thirty-three patients underwent VCE without domperidone pre-treatment. After 2 h, if the capsule remained intra-gastric, gastroscopy-assisted duodenal delivery was performed. Data was analysed using Mann-Whitney testing. Median oro-duodenal transit was 13 and 30 min in the untreated and domperidone groups, respectively (p = 0.01). Median oro-caecal transit was 242 and 267 min in the untreated and domperidone groups, respectively (p = 0.02). No difference in duodenal-caecal transit was seen (p = 0.60). Six percent of untreated and 13% of domperidone VCEs required gastroscopy-assisted duodenal capsule delivery (p = 0.65). Unexpectedly domperidone delayed VCE gastric transit. Most studies on domperidone prokinetic effects have been in diabetic gastroparesis, demonstrating that domperidone can achieve good symptomatic relief, but with mixed results for gastric emptying. Our study suggests that any antiemetic effects of domperidone are not mediated through accelerated gastric transit.

Intestinal lymphangiectasia, characterized by dilatation of intestinal lacteals, is rare. The major treatment for primary intestinal lymphangiectasia is dietary modification. Surgery to relieve symptoms and to clarify the etiology should be considered when medical treatment failed. This article reports a 49-year-old woman of solitary duodenal lymphangiectasia, who presented with epigastralgia and anemia. Her symptoms persisted with medical treatment. Surgery was finally performed to relieve the symptoms and to exclude the existence of underlying etiologies, with satisfactory effect. In conclusion, duodenal lymphangiectasia can present clinically as epigastralgia and chronic blood loss. Surgical resection may be resorted to relieve pain, control bleeding, and exclude underlying diseases in some patients. PMID:14669360

An ectopic opening of the common bile duct into the duodenal bulb is a very rare congenital malformation of the bile duct, which may cause a recurrent duodenal ulcer or biliary diseases including choledocholithiasis or cholangitis. ERCP plays major role in the diagnosis of this biliary malformation. We report a case of an ectopic opening of the common bile duct into the duodenal bulb, which was detected on the upper gastrointestinal series.

Effects of diphosphonate on kidney calcium content and duodenal absorption of 45calcium

International Nuclear Information System (INIS)

Goulding, A.; Cameron, V.

1978-01-01

In rats the relationships between EHDP-induced changes in serum calcium concentration, kidney calcium content and duodenal transport of 45 calcium were studied. Body weights and kidney weights were similar in all groups. EHDP administration was associated with an increase in serum calcium concentration and kidney calcium content, and a decrease in duodenal 45 calcium transport. In the EHDP-treated rats, there was a significant negative correlation between kidney calcium concentration and duodenal 45 calcium transport but no correlation between either kidney calcium content and serum calcium concentration (r = 0.116) or between serum calcium concentration and duodenal 45 calcium transport (r = 0.02). Further experiments will be needed to determine whether the demonstrated increase in kidney calcium content induced by EHDP administration was the cause of, or was secondary to, inhibition of 1, 25(OH) 2 D 3 synthesis.

Gastric polyps are usually found incidentally during upper gastrointestinal endoscopic examinations. These polyps are generally benign, with hyperplasia being the most common. While gastric polyps are often asymptomatic, they can cause gastric outlet obstruction. A 64 years-old female patient presented to our polyclinic with a history of approximately 2 months of weakness, occasional early nausea, vomiting after meals and epigastric pain. A polypoid lesion of approximately 25mm in diameter was detected in the antral area of the stomach, which prolapsed through the pylorus into the duodenal bulbus, and subsequently caused gastric outlet obstruction, as revealed by upper gastrointestinal endoscopy of the patient. The polyp was retrieved from the pyloric canal into the stomach with the aid of a tripod, and snare polypectomy was performed. Currently, widespread use of endoscopy has led to an increase in the frequency of detecting hyperplastic polyps. While most gastric polyps are asymptomatic, they can cause iron deficiency anemia, acute pancreatitis and more commonly, gastric outlet obstruction because of their antral location. Although there are no precise principles in the treatment of asymptomatic polyps, polyps >5mm should be removed due to the possibility of malignant transformation. According to the medical evidence, polypectomy is required for gastric hyperplastic polyps because of the risks of complication and malignancy. These cases can be successfully treated endoscopically.

Full Text Available 2.6% of pancreatic cancer patients have the primary manifestation of gastrointestinal bleeding. It is not feasible to stop the duodenal hemorrhage caused by the pancreatic cancer infiltration. A 43-year-old woman who was diagnosed as having pancreatic cancer with multiple hepatic metastases and duodenal infiltration was administered gemcitabine and S-1 combination therapy. During the chemotherapy, initially, bleeding occurred due to duodenal infiltration. However, we continued the chemotherapy and duodenal infiltration was markedly reduced in size and did not rebleed. Aggressive chemotherapy contributed to maintenance of performance status as well as improvement of quality of life for the patient.

Modeling data for pancreatitis in presence of a duodenal diverticula using logistic regression

Science.gov (United States)

Dineva, S.; Prodanova, K.; Mlachkova, D.

2013-12-01

The presence of a periampullary duodenal diverticulum (PDD) is often observed during upper digestive tract barium meal studies and endoscopic retrograde cholangiopancreatography (ERCP). A few papers reported that the diverticulum had something to do with the incidence of pancreatitis. The aim of this study is to investigate if the presence of duodenal diverticula predisposes to the development of a pancreatic disease. A total 3966 patients who had undergone ERCP were studied retrospectively. They were divided into 2 groups-with and without PDD. Patients with a duodenal diverticula had a higher rate of acute pancreatitis. The duodenal diverticula is a risk factor for acute idiopathic pancreatitis. A multiple logistic regression to obtain adjusted estimate of odds and to identify if a PDD is a predictor of acute or chronic pancreatitis was performed. The software package STATISTICA 10.0 was used for analyzing the real data.

2017-01-01

Combined pancreatic-duodenal injuries in blunt abdominal trauma are rare. These injuries are associated with high morbidity and mortality, and their emergent management is a challenge. We report a case of combined complete pancreatic (through the neck) and duodenal (first part) transections in a 24-year-old male secondary to blunt abdominal trauma following a motor vehicle crash. The duodenal stumps were closed separately and a gastrojejunostomy performed for intestinal continuity. The transacted head of pancreas main duct was suture ligated and parenchyma was over sewn and buttressed with omentum. The edge of the body and tail pancreatic segment was freshened and an end to side pancreatico-jejunostomy was fashioned. A drain was left in situ. Post operatively the patient developed a pancreatic fistula which resolved with conservative management. After ten months of follow up the patient was well and showed no signs and symptoms of pancreatic insufficiency. Lengthy, complex procedures in pancreatic injuries have been associated with poor outcomes. Distal pancreatectomy or Whipple's procedure for trauma are viable options for complete pancreatic transections. But when there is concern that the residual proximal pancreatic tissue is inadequate to provide endocrine or exocrine function, preservation of the pancreatic tissue distal to the injury becomes an option. Combined pancreatic and duodenal injuries are rare and often fatal. Early identification, resuscitation and surgical intervention is warranted. Because of the large number of possible combinations of injuries to the pancreas and duodenum, no one form of therapy is appropriate for all patients. Copyright © 2017 The Authors.

Duodenal tuberculosis

International Nuclear Information System (INIS)

Mirza, M.R.; Sarwar, M.

2004-01-01

Tuberculosis is a world wide communicable disease caused by tubercle bacilli discovered by Robert Kock in 1882. In 1993 WHO declared TB as a global emergency due to its world wide resurgence. It can involve any organ of the body. Abdomen is the fourth commonest site of involvement in the extra pulmonary tuberculosis after the lymph-nodes, skeletal and Genito urinary variants. In the gastro intestinal tract tuberculosis can affect any part from the mouth to the anus but ileocaecal area is a favourite location. Duodenal involvement is uncommon and accounts for only 2.5% of tuberculous enteritis. Major pathogens are Mycobacterium Tuberculosis and bovis and the usual route of entry is by direct penetration of the intestinal mucosa by swallowed organisms. (author)

To assess the efficacy and safety of arterial embolotherapy in patients with massive duodenal hemorrhage. Between January 1999 and June 2002, 25 patients (age: 34-81, mean 58, male: 19, female: 6) underwent arterial embolization for duodenal hemorrhage after failed endoscopic therapy. The hemorrhage originated from duodenal ulcer in sixteen patients, from cancer with duodenal invasion in five patients, from endoscopic sphincterectomy in two patients, and from pseudoaneurysm complicating acute pancreatitis in two patients. Hemorrhage was detected at endoscopy and an attempt was made to treat it endoscopically in all patients, but failed in each case. At angiography, direct bleeding signs such as contrast extravasation or pseudoaneurysm were demonstrated in nineteen patients. In the six patients without angiographic evidence of bleeding, blind embolization of the gastroduodenal artery was performed based on the endoscopic examination. Microcoil and gelfoam particles were used as embolic agents. Hemostasis was achieved immediately after embolotherapy in 21 patients (84%). Bleeding recurred in 4 patients (16%), and of these cases, one was successfully treated purely by endoscopic means, a second was reembolized three times due to bleeding from the collateral vessels of the tumor and the two others were treated by surgery. After the procedure, six patients died (24%). The causes of death were disseminated intravascular coagulopathy, multiorgan failure, sepsis and acute renal failure. The underlying diseases of the deceased patients were cancers with duodenal invasion (n=4) and abdominal aortic aneurysm with ischemic colitis (n=1). Transarterial embolotherapy in the case of massive duodenal hemorrhage is a safe and effective procedure. Even in the absence of angiographic evidence of bleeding, blind embolization of the gastroduodenal artery is effective for patients in the surgically high risk group

Full Text Available Duodenal intramural hematoma (DIH usually occurs in childhood and young adults following blunt abdominal trauma. It may also develop in the presence of coagulation disorders and may rarely be an iatrogenic outcome of endoscopic procedures. Management of DIH is usually a conservative approach. A case of intramural duodenal hematoma that developed following endoscopic epinephrine sclerotherapy and/or argon plasma coagulation and that was nonresponsive to conservative therapy in a patient with chronic renal failure who died from sepsis is being discussed in this report. Clinicians should be aware of such possible complications after endoscopic hemostasis in patients with coagulation disorders.

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. Suppression of pancreatic and duodenal secretion with octreotid improves significantly surgical treatment results.

Gastroduodenal tuberculosis is a rare location of abdominal tuberculosis. It usually occurs secondary to pulmonary tuberculosis. We report a case of a 63-year-old woman admitted to the referral center for symptoms of upper gastrointestinal obstruction caused by ulcerohypertrophic antroduodenal tuberculosis. The lesion was misdiagnosed as malignancy at endoscopy. Even at surgery, the lesion was considered gastric cancer and imposed an oncologic resection. The diagnosis was established in the presence of giant-cell granulomas with caseating necrosis in the surgical resected specimens. In our case, the rare gastroduodenal location of abdominal tuberculosis occurred as primary tuberculosis, in the absence of other identifiable locations.

Using immunohistochemical techniques we studied duodenal biopsies from 18 patients with coeliac disease and 24 patients with normal duodenal morphology. We had access to antisera against the following gastrointestinal peptides: cholecystokinin (CCK), gastric inhibitory peptide (GIP), gastrin-17, glucagon-enteroglucagon, motilin, neurotensin, pancreatic peptide (PP), secretin, somatostatin, substance P and vasoactive intestinal peptide (VIP). The somatostatin, GIP, CCK, and glucagon cells were increased in number in coeliac disease. The number of motilin cells was slightly increased, while secretin cells were reduced. Cells storing gastrin-17, substance P, or neurotensin were rare in all patients regardless of diagnosis. No PP immunoreactive cells were found and VIP was localised to neurons only. In biopsies from patients having a mucosa with ridging of villi the number of the various endocrine cell types did not differ from that in the control group. Images Fig. 2 PMID:385455

The effect of dietary Ca and vitamin D 3 on the duodenal Cd transport was observed in the rat using everted gut sac technique in vitro, 1. Duodenal Cd transport was significantly increased in vitamin D deficient rat, however, it was not influenced by dietary Ca. The duodenal tissue binding and/or uptake of Cd from mucosal incubation medium was neither influenced by vitamin D 3 nor dietary Ca. 2. The transported Cd to serosal medium was very little compared to the Cd binding and/or uptake of duodenal tissue, suggesting two steps mechanism for intestinal Cd transport. The first step is the transfer from mucosal medium to duodenal mucosa and the second step is from duodenal mucosa to serosal medium. The second step was influenced by vitamin D. These results suggested that a significant increase in hepatic Cd accumulation of vitamin D deficient rat could be ascribed to the increase in the intestinal Cd absorption. (author)

2015-03-01

To assess a possible association between inflammatory bowel disease (IBD) and the histologic finding in duodenal biopsy specimens of increased intraepithelial lymphocytes (IELs) with normal villous architecture. We identified all patients with duodenal biopsy specimens obtained between 2000 and 2010 showing increased IELs and normal architecture. Among the 74 such patients who also had IBD, we characterized the clinical features of IBD and reviewed all available upper gastrointestinal biopsy specimens. Fifty-eight patients had Crohn disease, 13 had ulcerative colitis, and three had IBD, type unclassified. No duodenal sample with increased IELs had other histologic features of IBD. Among gastric biopsy specimens from 34 patients with Crohn disease, nearly half (16) had focal gastritis. We propose that Crohn disease be included in the differential diagnosis for increased IELs with normal villous architecture in duodenal biopsy specimens, particularly when gastric biopsy specimens show focal gastritis.

We report a 64-year-old woman with duodenal varices who underwent balloon-occluded retrograde transvenous obliteration (B-RTO) complicated by intraprocedural variceal rupture. The patient developed shivering and a fever higher than 40 o C 3 days after the B-RTO procedure. A blood culture grew Entereobacter cloacoe. This case represents a rare septic complication of B-RTO for duodenal varices.

Is epidermal growth factor involved in development of duodenal polyps in familial polyposis coli?

DEFF Research Database (Denmark)

Poulsen, Steen Seier

1988-01-01

Duodenal adenomas are a frequent extracolonic manifestation in patients with familial polyposis coli (FPC). Epidermal growth factor (EGF), a polypeptide that stimulates cellular growth and differentiation, is localized in Paneth cells in the small intestine. In two patients with FPC, we found EGF...... immunoreactivity in duodenal adenomas. Numerous EGF immunoreactive Paneth cells were localized, not as usually, in the bottom of the crypts, but scattered along the crypts alone or in clusters. We do not know whether EGF is involved in the development of duodenal polyps in FPC patients, or whether the present...

Full Text Available Background: Helicobacter pylori is a major human gastric for various gastro duodenal diseases.A number of putative virulence factors such as dupA, homB, tnpA have been described. To date,none were found to be significantly associated with specific H. pylori-related diseases (e.g. gastric cancer and duodenal ulcer.Methods: the primary aim of this study was to test the H. pylori hrgA genotype isolated from 253 Iranian symptomatic patients to investigate possible association with clinical outcomes. The positive culture results were confirmed by glmM (genetic control for H. pylori PCR assay.Results: The results showed hrgA gene was detected in 44/253 strains (17.3%. Prevalence of the hrgA gene was relatively high in strains isolated from duodenal ulcer patients (P=0.0063; Odd ratio: 3.54; CI 95%: 1.42-8.77.Conclusions: In contrast our findings showed that the prevalence of hrgA in our control group (gastritis patients was 22.7% (P>0.05. Conclusively, hrgA gene is a good candidate as a discriminatory biomarker for patients with duodenal ulcer

Obstructing Gangliocytic Paraganglioma in the Third Portion of the Duodenum

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.

Full Text Available Duodenal varices (DV are rare in patients with portal hypertension secondary to liver disease. Their tendency to bleed is less common than in gastroesophageal varices, but can sometimes produce a life-threatening bleed. They are often difficult to diagnose and treat. We present a case of a 35-year-old man with parenchymal liver disease admitted with complaints of hematemesis and melena. Upper gastrointestinal endoscopy was performed and a duodenal varix, with stigmata of a recent bleed, was noted in the second part of the duodenum. Five milliliters of N-butyl-2-cyanoacrylate glue was injected into the varix leading to obliteration. A follow-up study with an endoscopic ultrasound and repeat endoscopy showed near total obturation of the varix and success of the therapy. This report concludes that glue injection can effectively be used as a first-line treatment for bleeding duodenal varices.

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.

Triple-Tube-Ostomy: A Novel Technique for the Surgical Treatment of Iatrogenic Duodenal Perforation

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.

To evaluate the efficacy and safety of empiric transcatheter arterial embolization (TAE) for patients with massive bleeding from duodenal ulcers. During January 2000 and December 2009, 59 patients with duodenal ulcer bleeding in whom TAE was attempted after endoscopic therapy failed were retrospectively analyzed. The patients were divided into empiric TAE (n = 36) and identifiable TAE (n = 23) groups according to angiographic findings with or without identification of the bleeding sites. The technical and clinical success rate, recurrent bleeding rate, procedure-related complications, and clinical outcomes were evaluated. The technical and clinical success rates of TAE were 100% and 83%. The recurrent bleeding rate, clinical success, duodenal stenosis, and 30-day mortality after TAE were not significantly different between the empiric and identifiable TAE groups. A high rate of technical and clinical success was obtained with empiric TAE comparable to identifiable TAE in patients with massive bleeding from duodenal ulcers. There were no severe complications. Empiric TAE is an effective and safe method when a bleeding site cannot determined by angiography. Copyright © 2011 SIR. Published by Elsevier Inc. All rights reserved.

Constitutional Syndrome, Ascites and Duodenal Thickening Presenting as Groove Pancreatitis

Full Text Available Groove pancreatitis (GP is a very infrequent subtype of chronic pancreatitis affecting the pancreatic-duodenal junction. It usually manifests in middle-aged men with a history of chronic alcoholism, though it has also been described in women and in individuals who do not consume alcohol[1]. Even though the underlying etiology is unclear, chronic alcohol consumption is known to increase the viscosity of the pancreatic juice and exacerbate the inflammatory process[2]. We present a case of GP that posed diagnostic difficulties because it manifested as ascites and duodenal thickening, with pancreatic imaging findings initially normal.

This study was conducted to evaluate an adapter-modified Ussing chamber for assessment of transport physiology in endoscopically obtained duodenal biopsies from healthy cats and dogs, as well as dogs with chronic enteropathies. 17 duodenal biopsies from five cats and 51 duodenal biopsies from 13 dogs were obtained. Samples were transferred into an adapter-modified Ussing chamber and sequentially exposed to various absorbagogues and secretagogues. Overall, 78.6% of duodenal samples obtained from cats responded to at least one compound. In duodenal biopsies obtained from dogs, the rate of overall response ranged from 87.5% (healthy individuals; n = 8), to 63.6% (animals exhibiting clinical signs of gastrointestinal disease and histopathological unremarkable duodenum; n = 15), and 32.1% (animals exhibiting clinical signs of gastrointestinal diseases and moderate to severe histopathological lesions; n = 28). Detailed information regarding the magnitude and duration of the response are provided. The adapter-modified Ussing chamber enables investigation of the absorptive and secretory capacity of endoscopically obtained duodenal biopsies from cats and dogs and has the potential to become a valuable research tool. The response of samples was correlated with histopathological findings. PMID:24378587

Endoscopic Decompression and Marsupialization of A Duodenal Duplication Cyst

Eliza I-Lin Sin

2018-06-01

Full Text Available Introduction: Duodenal duplication cysts are rare congenital foregut anomalies, accounting for 2%–12% of all gastrointestinal tract duplications. Surgical excision entails risk of injury to the pancreaticobiliary structures due to proximity or communication with the cyst. We present a case of duodenal duplication cyst in a 3 year-old boy who successfully underwent endoscopic decompression. Case report: AT is a young boy who first presented at 15 months of age with abdominal pain. There was one subsequent episode of pancreatitis. Ultrasonography showed the typical double wall sign of a duplication cyst and magnetic resonance cholangio-pancreatography showed a large 5 cm cyst postero-medial to the second part of the duodenum, communicating with the pancreaticobiliary system and causing dilatation of the proximal duodenum. He subsequently underwent successful endoscopic ultrasound guided decompression at 3 years of age under general anesthesia, and had an uneventful postoperative recovery. Conclusion: Endoscopic ultrasound guided assessment and treatment of gastrointestinal duplication cysts is increasingly reported in adults. To the best of our knowledge, only one case of endoscopic treatment of duodenal duplication cyst, in an older child, has been reported thus far in the paediatric literature. In this paper, we review the current literature and discuss the therapeutic options of this rare condition.

Full Text Available INTRODUCTION Perforated duodenal ulcer, the most catastrophic complication was Associated with high mortality in the past due to late presentation of the patients, delay in surgery and lack of antibiotics. Various authors state that the incidence of peptic ulcer disease and perforation has been declining for the past 3 decades. Because of advances in the medical therapy of peptic ulcer with a wide range of drugs the management of peptic ulcer disease has been changing and the role of surgery has been declining. Perforation is usually seen in 3rd and 4th decades with a male preponderance and the epidemiological trend is not the same worldwide. Incidence is slightly declining in western countries. The present study has been done during the period between 2013 and 2014 in S. V. R. R. Government general hospital Tirupati. AIMS AND OBJECTIVES The aim of the present study is to analyze the probable factors for increase in incidence of duodenal ulcer perforation, with particular emphasis on assessment of impact of H2 receptor antagonists and Proton Pump inhibitors on the incidence of perforation. STUDY SETTING S. V. Medical College, Department of General Surgery, Tirupati. STUDY PERIOD Patients attending S. V. Medical College, Department of General Surgery with perforation during the period from November 2013 to October 2014. INCLUSION CRITERIA Patients between age group of more than 14 years presenting with pain abdomen and who are diagnosed to have peritonitis due to duodenal ulcer perforation. EXCLUSION CRITERIA Patients with peritonitis due causes other than duodenal ulcer. STUDY METHOD Prospective Observational study among the selected patients. Total numbers of peptic ulcer cases that were admitted in this hospital and treated either medically or surgically were noted. The details of their clinical history and findings, investigation reports, operative findings, post-operative complications were recorded. Simple closure was performed for all the

Objective: To outline the various treatment options and outcomes in penetrating pancreatico-duodenal injuries with emphasis on the operative decision making strategies. Study Design: Descriptive study. Place and Duration of Study: Department of Surgery at Combined Military Hospital Peshawar, from 1st June 2008 to 30th May 2010. Patients and Methods: All combat casualties with penetrating pancreaticoduodenal injuries (PPDI) received in 'Emergency reception' of Combined Military Hospital, Peshawar were included. Data was taken from the patients medical charts and by personal evaluation and entered in a proforma. The variables used were age, sex, cause of the injury, haemo-dynamic status, conscious level, intensive care treatment duration, time to initial exploration, associated injury, grade of pancreatic injury according to Penetrating Abdominal Trauma Index (PATI) scoring system, grade of duodenal injury (according to PATI scoring system), total PATI score, operative repair, total hospital stay, morbidity, and mortality. Results: Twenty three patients having either or both of PPDI were included in the study out of 196 combat casualities. No case was excluded on basis of presence of associated injury. Mean age was 29.26 years (SD+-6.489) with only one (4.3%) case of female gender, the rest were male patients or soldiers. Nineteen (82.6%) cases had primary mechanism/cause of injury being splinters from Improvised Explosive Devices (IEDs) or bomb blasts; while 4 (17.4%) cases had Gunshot Wounds. Eighteen (78.3%) patients were haemo-dynamically stable on arrival while 5 (21.7%) patients were unstable. Mean duration of stay in hospital was 10.6 days, with a range of 1-19 days (cases with high PATI score and un-stable haemodynamic status died with-in 24 hrs). Most cases of pancreatico-duodenal injury were of mild severity i.e. grade-1 or 2 and we encountered no case of grade-5 PPDI. Most commonly occurring associated injury was to small gut. Overall mortality was 6 (26

The use of pyloric exclusion for treating duodenal trauma: case series

Gustavo Pereira Fraga

Full Text Available CONTEXT AND OBJECTIVES: Significant controversy exists regarding the best surgical treatment for complex duodenal injuries. The aims of this study were to report on a series of eight cases of duodenal repairs using pyloric exclusion and to describe reported complications or improvements in clinical outcomes among patients with complex duodenal trauma. DESIGN AND SETTING: Cross-sectional study followed by a case series in a university hospital. METHODS: Data on eight patients with duodenal trauma who underwent pyloric exclusion over a 17.5 year period were collected and analyzed. RESULTS: The causes of the injuries included penetrating gunshot wounds (GSW in five patients and motor vehicle accidents (blunt trauma in three patients. The time elapsed until surgery was longer in the blunt trauma group, while in one patient, the gunshot injury was initially missed and thus the procedure was carried out 36 hours after the original injury. The injuries were grade III (50% or IV (50% and the morbidity rate was 87.5%. Four patients (50% died during the postoperative period from complications, including hypovolemic shock (one patient, sepsis (peritonitis following the missed injury and pancreatitis with an anastomotic fistula (two patients. CONCLUSIONS: Pyloric exclusion was associated with multiple complications and a high mortality rate. This surgical technique is indicated for rare cases of complex injury to the duodenum and the surgeon should be aware that treatment with a minimalistic approach, with only primary repair, may be ideal.

We have recently evaluated a short endoscopic secretin test for exocrine pancreatic function. Bicarbonate concentration in duodenal juice is an important parameter in this test. Measurement of bicarbonate by back titration as the gold standard method is time consuming, expensive and technically difficult, thus a simplified method is warranted. We aimed to evaluate an automated spectrophotometric method in samples spanning the effective range of bicarbonate concentrations in duodenal juice. We also evaluated if freezing of samples before analyses would affect its results. Patients routinely examined with short endoscopic secretin test suspected to have decreased pancreatic function of various reasons were included. Bicarbonate in duodenal juice was quantified by back titration and automatic spectrophotometry. Both fresh and thawed samples were analysed spectrophotometrically. 177 samples from 71 patients were analysed. Correlation coefficient of all measurements was r = 0.98 (p titration gold standard. This is a major simplification of direct pancreas function testing, and allows a wider distribution of bicarbonate testing in duodenal juice. Extreme values for Bicarbonate concentration achieved by the autoanalyser method have to be interpreted with caution. Copyright © 2016 IAP and EPC. Published by Elsevier India Pvt Ltd.

Our understanding of the cause and treatment of peptic ulcer disease has changed dramatically over the last couple of decades. It was quite common some years ago to treat chronic ulcers surgically. These days, the operative treatment is restricted to the small proportion of ulcer patients who have complications such as perforation. The author reports seven cases of perforated duodenal ulcers seen in a surgical clinic between 1995 and 2001. Recommendations on the criteria for selecting the appropriate surgical intervention for patients with perforated duodenal ulcer are given. To decide on the appropriate surgical interventions for patients with perforated duodenal ulcer. These are case series of 7 patients who presented with perforated duodenal ulcers without a history of peptic ulcer disease. Seven patients presented with perforated duodenal ulcer 72 hours after perforation in a specialist surgical clinic in Kampala were analyzed. Appropriate management based on these patients is suggested. These patients were initially treated in upcountry clinics for acute gastritis from either alcohol consumption or suspected food poisoning. There was no duodenal ulcer history. As a result, they came to specialist surgical clinic more than 72 hours after perforation. Diagnosis of perforated duodenal ulcer was made and they were operated using the appropriate surgical intervention. Diagnosis of hangovers and acute gastritis from alcoholic consumption or suspected food poisoning should be treated with suspicion because the symptoms and signs may mimic perforated peptic ulcer in "silent" chronic ulcers. The final decision on the appropriate surgical intervention for patients with perforated duodenal ulcer stratifies them into two groups: The previously fit patients who have relatively mild physiological compromise imposed on previously healthy organ system by the perforation can withstand the operative stress of definitive procedure. The Second category includes patients who are

Down syndrome is an autosomal chromosome disorder, characterized by intellectual disability and muscle hypotonia. Muscle hypotonia is observed from neonates to adulthood in Down syndrome patients, but muscle hypertonicity is extremely unusual in this syndrome. During a study period of nine years, we found three patients with severe spastic quadriplegia among 20 cases with Down syndrome and congenital duodenal stenosis/atresia (3/20). However, we could find no patient with spastic quadriplegia among 644 cases with Down syndrome without congenital duodenal stenosis/atresia during the same period (0/644, P quadriplegia among 17 patients with congenital duodenal stenosis/atresia without Down syndrome admitted during the same period to use as a control group (0/17, P quadriplegia in patients with Down syndrome. Long-term survival is improving, and the large majority of people with Down syndrome are expected to live well into adult life. Management and further study for the various problems, representing a low prevalence but serious and specific to patients with Down syndrome, are required to improve their quality of life. © 2012 The Authors.

To investigate the roles of the neuropeptides vasoactive intestinal peptide (VIP), substance P (SP), and calcitonin gene-related peptide (CGRP) in chronic gastritis and duodenitis in children. Biopsy samples from the gastric and duodenal mucosa of 52 patients and 30 control subjects were obtained. Samples were taken for pathological examination, immunohistochemical staining, enzyme activity measurements and quantitative measurements of tissue peptide levels. We observed differential effects of the disease on peptide levels, which were somewhat different from previously reported changes in chronic gastritis in adults. Specifically, SP was increased and CGRP and VIP were decreased in patients with gastritis. The changes were more prominent at sites where gastritis was severe, but significant changes were also observed in neighboring areas where gastritis was less severe. Furthermore, the degree of changes was correlated with the pathological grade of the disease. The expression of CD10, the enzyme primarily involved in SP hydrolysis, was also decreased in patients with duodenitis. Based on these findings, we propose that decreased levels of VIP and CGRP and increased levels of SP contribute to pathological changes in gastric mucosa. Hence, new treatments targeting these molecules may have therapeutic and preventive effects.

Helicobacter pylori (H. pylori) infection underlies gastric ulcer disease, gastric cancer and duodenal ulcer disease. The disease expression reflects the pattern and extent of gastritis/gastric atrophy (i.e., duodenal ulcer with non-atrophic and gastric ulcer and gastric cancer with atrophic gastritis). Gastric and duodenal ulcers and gastric cancer have been known for thousands of years. Ulcers are generally non-fatal and until the 20th century were difficult to diagnose. However, the presence and pattern of gastritis in past civilizations can be deduced based on the diseases present. It has been suggested that gastric ulcer and duodenal ulcer both arose or became more frequent in Europe in the 19th century. Here, we show that gastric cancer and gastric ulcer were present throughout the 17th to 19th centuries consistent with atrophic gastritis being the predominant pattern, as it proved to be when it could be examined directly in the late 19th century. The environment before the 20th century favored acquisition of H. pylori infection and atrophic gastritis (e.g., poor sanitation and standards of living, seasonal diets poor in fresh fruits and vegetables, especially in winter, vitamin deficiencies, and frequent febrile infections in childhood). The latter part of the 19th century saw improvements in standards of living, sanitation, and diets with a corresponding decrease in rate of development of atrophic gastritis allowing duodenal ulcers to become more prominent. In the early 20th century physician's believed they could diagnose ulcers clinically and that the diagnosis required hospitalization for "surgical disease" or for "Sippy" diets. We show that while H. pylori remained common and virulent in Europe and the United States, environmental changes resulted in changes of the pattern of gastritis producing a change in the manifestations of H. pylori infections and subsequently to a rapid decline in transmission and a rapid decline in all H. pylori-related diseases.

To see the histological outcome of duodenal biopsies done in patients clinically suspected of celiac disease. Study Design: Prospective descriptive study. Place and Duration of Study: Histopathology Department, Army Medical College Rawalpindi, from 1 Jan 2017 to 30 Jun 2017. Material and Methods: One hundred (100) cases were included in the study. Duodenal biopsies done in patients clinically suspected of celiac disease were included in the study. Inadequate biopsies were excluded from the study. All the normal and abnormal histological features were noted to make the diagnosis. Data was entered and analyzed by using SPSS version 17. Results: Duodenal biopsies of 100 patients, done in clinically suspected cases of celiac disease were analyzed histologically. Out of these 100 cases, 46 cases (46%) showed histological features consistent with celiac disease, while 38 cases (38%) revealed chronic non specific duodenitis, 2 cases (2%) were of giardiasis, while 14 biopsies (14%) were unremarkable with no significant pathology. Conclusion: A significant number of cases clinically suspected of celiac disease may not be showing histological features consistent with celiac disease on duodenal biopsies. Due to the changing presentation of disease, as well as the recognition of a number of potential clinical and histopathological mimics, communication between pathologists and gastroenterologists is essential for appropriate interpretation of duodenal biopsy specimens.

Objectives. Zollinger-Ellison Syndrome (ZES) results in hypersecretion of gastric acid (via gastrinoma) leading to peptic ulcers, diarrhea, and abdominal pain. We describe the novel discovery of hypertrophic, heterotopic gastric mucosa in the proximal duodenal bulb in patients with ZES, which we hypothesize results in an increased incidence of postbulbar ulcers in patients with ZES (a mechanism previously unreported). We determined the incidence of the novel finding of duodenal gastric oxyntic hypertrophic heterotopia (GOH) in patients with ZES. Methods. Seven patients with ZES were enrolled. The diagnosis of ZES was established by hypergastrinemia, gastric acid hypersecretion, and a positive secretin test or based on biopsy specimens (evaluated via tissue staining). Basal acid output (BAO) and baseline gastrin secretion were determined by established methods. Endoscopic examinations with methylene blue staining and biopsy of the gastric and duodenal mucosa were conducted in all patients every 3–6 months for an average of 5 years. Results. The duodenal mucosa demonstrated hypertrophic GOH in 5 out of 7 patients with ZES and an intact stomach and duodenum. Biopsies from the bowel mucosa demonstrated patchy replacement of surface epithelium by gastric-type epithelium with hypertrophic oxyntic glands in the lamina propria in 5 patients. Two of the patients had no evidence of GOH in the duodenal bulb. Patients with GOH had an average serum gastrin level of 1245 pg/mL and BAO of 2.92 mEq/hr versus 724 pg/mL and 0.8 mEq/hr in patients without GOH. Conclusions. This study demonstrated the presence of duodenal mucosa with GOH in 5 out of 7 patients with ZES and an intact stomach and duodenum. The presence of hypertrophic and heterotopic gastric mucosa is proposed to result from increased gastrin levels and may contribute to the increased incidence of postbulbar ulcers in these patients.

Because a traditional rendezvous (RV) technique implies stretching of the papilla, possibly leading to post-ERCP pancreatitis, an alternative duodenal RV technique was evaluated. The aim was to assess the effectiveness, safety, and amount of time spent performing duodenal RV versus traditional RV cannulation in orthotopic liver transplantation patients with a T-tube. We retrospectively reviewed data from a prospective ERCP database held by our university hospital. Twenty patients with a T-tube who had undergone ERCP for biliary adverse events after orthotopic liver transplantation were included. The successful cannulation rate, the amount of time spent performing cannulation, the post-ERCP pancreatitis rate, and hyperamylasemia 24 hours after the procedure were recorded. Successful cannulation was achieved by the duodenal RV technique in 9 of 10 patients (90%), taking 146 seconds (interquartile range 63-341 seconds) with a short learning curve effect. An unsuccessful duodenal RV procedure occurred because of the angulation of the hydrophilic tip of the guidewire while crossing the papilla, thus preventing cannulation. Successful cannulation was achieved by the traditional RV technique in all cases (N = 11), including the failed duodenal RV technique, taking 374 seconds (interquartile range 320-410 seconds) (P < .05 vs duodenal RV). However, no post-ERCP pancreatitis occurred after using the duodenal RV technique compared with 2 episodes of mild pancreatitis after using the traditional RV technique. Twenty-four hours after the procedure, the median amylasemia level was 84 IU/L (interquartile range 49-105 IU/L) and 265 IU/L (interquartile range 73-2945 IU/L) for the duodenal versus traditional RV techniques, respectively (P = not significant). In patients with a T-tube after liver transplantation, the duodenal RV technique was not associated with post-ERCP pancreatitis, presumably because of the reduction of stress on the major papilla. Cannulation by using the

Purpose: To determine the incidence of duodenal toxicity in patients receiving intensity modulated radiation therapy (IMRT) for treatment of para-aortic nodes and to identify dosimetric parameters predictive of late duodenal toxicity. Methods and Materials: We identified 105 eligible patients with gynecologic malignancies who were treated with IMRT for gross metastatic disease in the para-aortic nodes from January 1, 2005, through December 31, 2009. Patients were treated to a nodal clinical target volume to 45 to 50.4 Gy with a boost to 60 to 66 Gy. The duodenum was contoured, and dosimetric data were exported for analysis. Duodenal toxicity was scored according to Radiation Therapy Oncology Group criteria. Univariate Cox proportional hazards analysis and recursive partitioning analysis were used to determine associations between dosimetric variables and time to toxicity and to identify the optimal threshold that separated patients according to risk of toxicity. Results: Nine of the 105 patients experienced grade 2 to grade 5 duodenal toxicity, confirmed by endoscopy in all cases. The 3-year actuarial rate of any duodenal toxicity was 11.7%. A larger volume of the duodenum receiving 55 Gy (V55) was associated with higher rates of duodenal toxicity. The 3-year actuarial rates of duodenal toxicity with V55 above and below 15 cm{sup 3} were 48.6% and 7.4%, respectively (P<.01). In Cox univariate analysis of dosimetric variables, V55 was associated with duodenal toxicity (P=.029). In recursive partitioning analysis, V55 less than 13.94% segregated all patients with duodenal toxicity. Conclusions: Dose-escalated IMRT can safely and effectively treat para-aortic nodal disease in gynecologic malignancies, provided that care is taken to limit the dose to the duodenum to reduce the risk of late duodenal toxicity. Limiting V55 to below 15 cm{sup 3} may reduce the risk of duodenal complications. In cases where the treatment cannot be delivered within these constraints

Objectives Duodenal perforation by an inferior vena cava filter is rare and life threatening. Our objective is to find out number of occurrences and compare diagnosis and treatments. Method The reference list of Malgor's review in 2012 was considered as well as all new articles with eligible features. Search was conducted on specific databases: MEDLINE, Web of Sciences, and Literatura Latino-Americana e do Caribe em Ciências da Saúde. Results Most of the patients presented with upper abdominal pain and the use of radiologic studies was crucial for diagnosis. The most common treatment was laparotomy with filter or strut removal plus duodenum repair. However, clinical conditions of patients must be considered and the endovascular technique with endograft deployment into inferior vena cava may be an alternative. Conclusion Duodenal perforation by an inferior vena cava filter is uncommon and in high-risk surgical patients endovascular repair must be considered.

We wanted to evaluate the usefulness of a new type of a complex expandable nitinol stent that was designed to reduce the stent's propensity to migration during the treatment of malignant gastroduodenal obstructions. Two types of expandable nitinol stent were constructed by weaving a single thread of 0.2mm nitinol wire in a tubular configuration: an uncovered stent 18mm in diameter and a covered stent 16mm in diameter. Both ends of the covered stent were fabricated by coaxially inserting the covered stent into the tubular uncovered stent and then attaching the two stents together with using nylon monofilament. Under fluoroscopic guidance, the stent was placed in 29 consecutive patients (20 men and 9 women, mean age: 65 years) who were suffering with malignant gastric outlet obstruction (n=20), duodenal obstruction (n=6) or combined obstruction (n=3). Clinical improvement was assessed by comparing the food intake capacity before and after the procedure. The complications were investigated during the follow up period. Stent placement was successful in all the patients. After stent placement, the symptoms improved in all but one patient. During the follow up, stent migration occurred in one patient (3%) at 34 days after the procedure. Despite the stent migration, the patient was able to resume a soft diet. Six patients developed recurrent symptoms of obstruction with tumor overgrowth at a mean of 145 days after the procedure; all the patients underwent coaxial placement of an additional stent with good results. One patient showed recurrence of obstruction due to tumor in-growth, and this was treated by placement of a second stent. Two patients with stent placement in the duodenum suffered from jaundice 26 days and 65 days, respectively, after their procedures. Placement of the newly designed complex expandable nitinol stent seems to be effective for the palliative treatment of malignant gastroduodenal obstructions.

Role of duodenal mucosal nerve endings in the acid-induced duodenogastric sensorimotor reflex: effect of benzocaine in healthy humans.

Duodenal acid exposure induces a duodenogastric reflex resulting in gastric relaxation, inhibition of antral motility, and sensitization of the proximal stomach to distension. Duodenal hypersensitivity to acid has been identified as a potential pathogenic mechanism in functional dyspepsia. The nature and localization of the duodenal acid-sensitive receptors are still elusive. We hypothesize that acid directly activates superficial afferent nerve endings in the duodenal mucosa, triggering the duodenogastric reflex. In a double-blind, randomized, crossover study in 13 healthy volunteers, benzocaine, a local anesthetic, vs saline was perfused in the duodenum 15 min before duodenal acid perfusion. Gastric responses were monitored by a barostat. Stepwise isobaric gastric distensions were performed before and during acid perfusion. Symptoms were evaluated by visual analogue scales for six dyspeptic symptoms and an overall perception score. Benzocaine perfusion caused a relaxation of the stomach prior to duodenal acidification, indicating the existence of an excitatory duodenogastric tone. Pretreatment of the duodenum with benzocaine reduced the acid-induced gastric relaxation by 50% and abolished the inhibition of phasic motility of the proximal stomach. Finally, sensitization to distension was more pronounced in the benzocaine condition because of higher proximal gastric volumes. These findings support a model in which different neuronal subpopulations are responsible for the motor and sensory limb of the acid-sensitive duodenogastric reflex, making benzocaine an unsuitable drug to treat duodenal hypersensitivity to acid. These data provide more insight in the contribution of duodenal neuronal input to gastric physiology in the fasting state. © 2013 Blackwell Publishing Ltd.

We report the incidence of peptic ulcers (duodenal, pyloric canal, gastric, and combined) verified by radiologic, endoscopic, or surgical evidence in a large Health Maintenance Organization (HMO) in Los Angeles, California. For members age 15 and above, the peptic ulcer incidence rate was 0.86 per 1,000 person-years (p-y) (males 1.10, females 0.63). The male to female sex ratio was 1.7. Two hundred twenty-two duodenal, 17 pyloric canal, 89 gastric, and 21 combined first-time diagnosed ulcer cases were located. For duodenal and pyloric canal ulcer, the incidence rate for members age 15 and above was 0.58 per 1,000 p-y (males 0.76, females 0.40). For gastric ulcer, the incidence rate for members age 15 and above was 0.21 per 1,000 p-y (males 0.23, females 0.18). The combined ulcer rate was 0.05 per 1,000 p-y (males 0.07, females 0.02). Gastric ulcer rates were two times higher in 1980 than in 1977. Peptic ulcer age-specific incidence rates increased with age. Incidence rates were much lower than those reported in previous studies, but the gastric to duodenal ulcer ratio and the age and sex relation to ulcer incidence were similar to those previously reported.

Full Text Available Background: Enteroendocrine cells are essential for the regulation of glucose metabolism, but it is unknown whether they are associated with clinical features of metabolic syndrome (MetS and fasting plasma metabolites. Objective: We aimed to identify fasting plasma metabolites that associate with duodenal L cell, K cell and delta cell densities in subjects with MetS with ranging levels of insulin resistance. Research design and methods: In this cross-sectional study, we evaluated L, K and delta cell density in duodenal biopsies from treatment-naïve males with MetS using machine-learning methodology. Results: We identified specific clinical biomarkers and plasma metabolites associated with L cell and delta cell density. L cell density was associated with increased plasma metabolite levels including symmetrical dimethylarginine, 3-aminoisobutyric acid, kynurenine and glycine. In turn, these L cell-linked fasting plasma metabolites correlated with clinical features of MetS. Conclusions: Our results indicate a link between duodenal L cells, plasma metabolites and clinical characteristics of MetS. We conclude that duodenal L cells associate with plasma metabolites that have been implicated in human glucose metabolism homeostasis. Disentangling the causal relation between L cells and these metabolites might help to improve the (small intestinal-driven pathophysiology behind insulin resistance in human obesity.

The present study extends our earlier observations on gastrointestinal pathology in thorax-irradiated female CFLP mice. It shows that exposure of the lower mediastinum to single doses of 14-30 Gy X rays results in the formation of the proximal duodenal ulcer accompanied frequently by erosion of the antral gastric mucosa. X irradiation of the lateral thoracic fields is responsible for single ulcers in the proximity of duodenal papilla, often associated with a circumscribed area of degeneration of the fundic mucosa of the stomach. In view of the small amount of radiation received by the subdiaphragmatic parts of the alimentary tract, these gastro-duodenal lesions represent abscopal effects of thoracic irradiation

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.

There is a high prevalence of gastro-duodenal disease in sub-Saharan Africa. Peptic ulcer disease in dyspeptic patients, 24.5%, was comparable to prevalence of gastro-duodenal disease among symptomatic individuals in developed countries (12 - 25%). Limited data exists regarding its associated risk factors despite accumulating evidence indicating that gastroduodenal disease is common in Ghana. This study investigates risk factors associated with gastro-duodenal disease at the Korle-Bu Teaching Hospital, Accra, Ghana. This study utilized a cross-sectional design to consecutively recruit patients referred with upper gastro-intestinal symptoms for endoscopy. The study questionnaire was administered to study participants. Helicobacter pylori infection was confirmed by rapid-urease examination at endoscopy. Of 242 patients sampled; 64 had duodenal ulcer, 66 gastric ulcer, 27gastric cancer and 64 non-ulcer dyspepsia. Nineteen (19) had duodenal and gastric ulcer while 2 had gastric ulcer and cancer. A third (32.6%) of patients had history of NSAID-use. H. pyloriwas associated with gastric ulcer (p=0.033) and duodenal ulcer (p=0.001). There was an increased prevalence of duodenal ulcer in H. pylori-infected patients taking NSAIDs, P=0.003. H. pylori was a major risk factor for peptic ulcer disease. However, NSAID-related gastro-duodenal injury has been shown to be common in H. pylori infected patients. It highlights the need for awareness of the adverse gastro-intestinal effects in a H. pylori endemic area.

Full Text Available Peptic ulcers are a serious problem worldwide, and affect about 4 million people each year. Their etiology is connected with the presence of Helicobacter pylori, the act of smoking, drinking alcohol, being stress, and taking excessively nonsteroidal anti-inflammatory drugs, as well as steroids. The most common symptoms are abdominal pain, nausea, chest pain and fatigue, while less frequent symptoms include vomiting and weight loss. Helicobacter pylori is responsible for about 80% of gastric and 90% of duodenal ulcer cases. In this work, an analysis is made of a correlation between stomach or duodenal ulcer and gender, residence and number of patients hospitalized in the Almaty hospital №1, from 2009-2012, in order to learn about trends in the incidence of these diseases in Kazakhstan. A total number of 950 patients with stomach and duodenal ulcers, in 2009-2012, were questioned. The patient’s residence, gender and stomach or duodenal ulcer problem were taken into account in the study. The result of this work reveals that the largest amount of hospitalized patients suffering from stomach or duodenal ulcers came from urban areas. Moreover, more women than men suffered from peptic ulcers. Furthermore, the number of patients admitted to the hospital due to duodenal ulcers did not show any variation throughout the study. However, the least number of patients suffering from gastric ulcers was noticed in December 2009, and the greatest was in October and November 2011. The obtained data show that ulcers are a serious problem in Kazakhstan.

To assess the feasibility and safety of a pancreas-preserving total duodenectomy in the management of severe duodenal injury caused by abdominal trauma. Two patients with both extensive injury of the duodenum and diffuse peritonitis underwent pancreas preserving total duodenectomy at our tertiary care centre. These two young male patients (age 20 and 22 years) presented 2 days and 6 hours respectively following blunt abdominal trauma. The duodenum was almost completely separated from the pancreas. Ampulla was seen as a button on the pancreas. Following total duodenectomy, reconstruction was performed by suturing the jejunum to the head of the pancreas anteriorly and posteriorly away from the ampulla (invagination of the pancreas into the jejunum). There were no complications attributable to the procedure. Both patients are well on follow up. A Pancreas-preserving total duodenectomy offers a safe alternative to the Whipple procedure in managing complex duodenal injury. This procedure avoids unnecessary resection of the adjacent pancreas and anastomosis to undilated hepatic and pancreatic ducts.

Full Text Available Aim: This study was designed for clinical and laboratory evaluation of intestinal obstruction (IO in buffaloes (Bubalus bubalis with special emphasis on the diagnostic value of ultrasonographic findings. Materials and Methods: A total number of 30 buffaloes were included in the study and divided into 2 groups: Healthy (n=10 and diseased group (n=20. Diseased buffaloes were admitted to the Veterinary Teaching Hospital at Assiut University, Egypt, with a history of anorexia, abdominal pain, various degrees of abdominal distention, and absence or presence of scanty mucoid faces. These animals were subjected to clinical and ultrasonographic as well as laboratory examinations. Results: Based on ultrasonographic findings, various forms of IO were diagnosed. Functional obstruction, paralytic ileus, was diagnosed in 17 cases (85% while mechanical IO was diagnosed only in 3 cases (15%. Out of 17 cases of paralytic ileus, both proximal and distal ileuses were successfully imaged in 8 and 9 cases, respectively. Proximal ileus was imaged from the right dorsal flank region as a single dilated loop of diameter >6 cm, while distal ileus was imaged as multiple dilated loops of diameter <6 cm. Mechanical obstruction due to duodenal intussusception was visualized as two concentric rings with outer echogenic wall and hypoechoic lumen. All cases of IO showed leukocytosis, hypoproteinemia, and increased activity of alkaline phosphatase and aspartate aminotransferase. Conclusion: Ultrasonography proved to be an essential tool for diagnosis and differential diagnosis of various forms of IO in buffaloes.

The purpose of this paper is to describe our experience with endovascular obliteration of duodenal varices in patients with liver cirrhosis and portal hypertension. Balloon-occluded transvenous retrograde and percutaneous transhepatic anterograde embolizations were performed for duodenal varices in five patients with liver cirrhosis, portal hypertension, and decreased liver function. All patients had undergone previous endoscopic treatments that failed to stop bleeding and were poor surgical candidates. Temporary balloon occlusion catheters were used to achieve accumulation of an ethanolamine oleate-iopamidol mixture inside the varices. Elimination of the varices was successful in all patients. Retrograde transvenous obliteration via efferent veins to the inferior vena cava was enough to achieve adequate sclerosant accumulation in three patients. A combined anterograde-retrograde embolization was used in one patient with balloon occlusion of afferent and efferent veins. Transhepatic embolization through the afferent vein was performed in one patient under balloon occlusion of both efferent and afferent veins. There was complete variceal thrombosis and no bleeding was observed at follow-up. No major complications were recorded. Endovascular obliteration of duodenal varices is a feasible and safe alternative procedure for managing patients with portal hypertension and hemorrhage from this source. (orig.)

[Comparative pathology of early stress-induced changes in the duodenal mucosa in laboratory rats and in humans].

Peychl, L; Brejcha, A

2003-01-01

Our presentation comprises results of two studies: The first was an experimental investigation of 60 Wistar-strain rats used in a toxicological study. The other part analysed stress changes in the duodenal mucosa in the human autopsy material. Both humans and rats had been exposed to stress and showed similar histological changes. In the rats the same duodenal lesions were present both in the test group and the control animals in the toxicological study. Lesions consisted of oedema of the duodenal villi and erosions in the tips of the villi. We believe that in the experimental group the stress was caused by restraining the animals by daily introduction of the gastric metallic tube, by taking blood from the retrobulbar plexus, and by anaesthesia. The autopsy study comprised 35 cases displaying congestion and macroscopically recognizable multifocal bleeding into the duodenal mucosal folds. The microscopic investigation revealed bleeding into the mucosal villi and small erosions. In some cases there were cuneiform mucosal infarcts extending into the submucosa. In the humans, severe cardiovascular diseases and circulatory disturbances represented the main causes of the stress. Local hypoxia and gastric juice acidity were involved in the pathogenesis of the duodenal mucosal changes.

Mycophenolate mofetil (MMF) is an immunosupressor agent frequently used in patients after bone marrow or solid organ transplants. The most common adverse reactions of the drug are gastrointestinal, specially diarrhea and vomiting. We report a 53-year-old male, that received a heart transplant receiving immunosuppression with cyclosporine, mycophenolate mofetil and prednisone. Six months after the transplant, the patient started with diarrhea, anorexia and weight loss. A duodenal biopsy showed villous atrophy. Celiac disease and the presence of parasites were discarded. Mycophenolate mofetil was discontinued and one week later, diarrhea subsided. Two months later the patient was asymptomatic and recovered weight. A new duodenal biopsy showed absence of villous atrophy.

The publication provides an overview of duodenal X-ray diagnostics with the aid of barium meals in 1362 patients. The introducing paragraphs deal with the topographic anatomy of the region and the methodics of X-ray investigation. The chapter entitled ''processes at the duodenum itself'' describes mainly ulcers, diverticula, congenital anomalies, tumors and inflammations. The neighbourhood processes comprise in the first place diseases having their origin at the pancreas and bile ducts. As a conclusion, endoscopic rectograde cholangio-pancreaticography and percutaneous transhepatic cholangiography are pointed out as advanced X-ray investigation methods. In the annex of X-ray images some of the described phenomena are shown in exemplary manner. (orig./MG) [de

The endoscopic appearance of duodenitis is a common finding in patients undergoing endoscopy because of epigastric pain however, the relationship of the visual findings to histology is poorly defined. We set out to ascertain if there was a correlation between the endoscopic and histological appearances of the duodenal mucosa. Consecutive patients with epigastric pain referred for diagnostic gastroduodenoscopy were studied. The visual appearances of 'duodenitis' (erythema, erosions and sub-epithelial haemorrhage) were reported independently by two endoscopists. Duodenal biopsies were taken and assessed for: neutrophil infiltrate, mononuclear infiltrate, gastric metaplasia, villous atrophy and a breach in the mucosa. H pylori status was determined. Of the 93 patients with endoscopic features of duodenitis an increase in histological markers of inflammation was found in 75 (81%). However, histological inflammation was absent or minimal in 68 (73%). Conversely, biopsies from normal-looking mucosa revealed histological evidence of inflammation in 26 (27%). For patients with the endoscopic features of duodenitis the positive & negative predictive value for neutrophilic infiltrate was 39% and 98% respectively. Biopsies from erosions confirmed a breach in the mucosa in only 2 of 40 patients. Neutrophilic infiltrate occurred with NSAI ingestion and infection with H pylori. The endoscopic appearance of the duodenal mucosa is unreliable in determining the presence of histological inflammation. The endoscopic appearance of 'erosions' is not usually associated with a mucosal breach.

Is Helicobacter pylori Infection the Primary Cause of Duodenal Ulceration or a Secondary Factor? A Review of the Evidence

Full Text Available Helicobacter pylori (H. pylori has a role in the multifactorial etiology of peptic ulcer disease. A link between H. pylori infection and duodenal ulcer disease is now established. Other contributing factors and their interaction with the organism may initiate the ulcerative process. The fact that eradication of H. pylori infection leads to a long-term cure in the majority of duodenal ulcer patients and the fact that the prevalence of infection is higher in ulcer patients than in the normal population are cogent arguments in favor of it being the primary cause of the ulceration. Against this concept there are issues that need explanation such as the reason why only a minority of infected persons develop duodenal ulceration when infection with H. pylori is widespread. There is evidence that H. pylori infection has been prevalent for several centuries, yet duodenal ulceration became common at the beginning of the twentieth century. The prevalence of duodenal ulceration is not higher in countries with a high prevalence of H. pylori infection. This paper debate puts forth the point of view of two groups of workers in this field whether H. pylori infection is the primary cause of duodenal ulcer disease or a secondary factor.

Oral administration of synthetic human urogastrone promotes healing of chronic duodenal ulcers in rats

1986-01-01

The effect of oral administration of synthetic human epidermal growth factor/urogastrone (EGF/URO) on healing of chronic duodenal ulcers induced by cysteamine in rats was investigated and compared with that of cimetidine, a H2-receptor antagonist. After 25 and 50 days of treatment, synthetic human...... EGF/URO significantly increased healing of chronic duodenal ulcers to the same extent as cimetidine. Combined treatment with synthetic human EGF/URO and cimetidine for 25 days was more effective than synthetic human EGF/URO given alone, whereas combined treatment for 50 days was significantly more...... human EGF/URO is a potent inhibitor of gastric acid secretion when administered intravenously, but had no effect on acid secretion when given intraduodenally, which suggests that the effect of synthetic human EGF/URO is a direct action on the duodenal mucosa. In conclusion, this study showed that oral...

Full Text Available Abstract Background The prevalence of H. pylori is as high as 60–70% in Chinese population. Although duodenal ulcer and gastric cancer are both caused by H. pylori, they are at opposite ends of the spectrum and as such are considered mutually exclusive. Duodenal ulcer promoting (dupA gene was reported to be associated with duodenal ulcer development. The aim of this study was to determine the prevalence of dupA gene of Helicobacter pylori in patients with various gastroduodenal diseases and to explore the association between the gene and other virulence factors. Methods H. pylori were isolated from gastric biopsies of patients with chronic gastritis, duodenal ulcer (DU, gastric ulcer (GU, or non-cardia gastric carcinoma. The dupA, cagA, vacA, iceA and babA2 genotypes were determined by polymerase chain reaction. Histological features of gastric mucosal biopsy specimens were graded based on the scoring system proposed by the updated Sydney system. IL-1β polymorphism was investigated using restriction fragment length polymorphism. Results Isolates from 360 patients including 133 with chronic gastritis, 101 with DU, 47 with GU, and 79 with non-cardia gastric carcinoma were examined. The dupA gene was detected in 35.3% (127/360 and the prevalence DU patients was significantly greater than that in gastric cancer or GU patients (45.5% vs. 24.1% and 23.4%, P dupA-positive strains had higher scores for chronic inflammation compared to those with dupA-negative strains (2.36 vs. 2.24, p = 0.058. The presence of dupA was not associated with the cagA, vacA, iceA and babA 2 genotypes or with IL-1β polymorphisms. Conclusion In China the prevalence of dupA gene was highest in DU and inversely related to GU and gastric cancer.

Williams Nigel

2006-12-01

Full Text Available Abstract Background Colo-duodenal fistula is a rare complication of malignant and inflammatory bowel disease. Cases with malignant colo-duodenal fistulae can present with symptoms from the primary, from the fistula or from metastatic disease. The fistula often results in diarrhoea and vomiting with dramatic weight loss. Upper abdominal pain is usually present as is general malaise both from the presence of the disease and from the metabolic sequelae it causes. The diarrhoea relates to colonic bacterial contamination of the upper intestines rather than to a pure mechanical effect. Vomiting may be faeculant or truly faecal and eructation foul smelling but in the case reports this 'classic' symptomatology was often absent despite a fistula being present and patent enough to allow barium through it. Occasionally patients will present with a gastro-intestinal bleed. Case presentation We present an unusual case of colorectal carcinoma, where a 65 year old male patient presented with diarrhoea and vomiting secondary to a malignant colo-duodenal fistula near the hepatic flexure. Adenocarcinoma was confirmed on histology from a biopsy obtained during the patient's oesophageogastroduodenoscopy, and the fistula was demonstrated in his barium enema. Staging computed tomography showed a locally advanced carcinoma of the proximal transverse colon, with a fistula to the duodenum and regional lymphadenopathy. The patient was also found to have subcutaneous metastasis. Following discussions at the multidisciplinary meeting, this patient was referred for palliation, and died within 4 months after discharge from hospital. Conclusion We present the case, discuss the management and review the literature. Colo-duodenal fistulae from colonic primaries are rare but early diagnosis may allow curative surgery. This case emphasises the importance of accurate staging and repeated clinical examination.

Radioimmunoassay of gastrin level in the blood was performed in 20 controls, 12 patients with duodenal ulcer, 13 patients with atrophic gastritis and 14 patients with Addison-Biermer's disease. Gastrin level in the serum of the patients with duodenal ulcer did not differ significantly from that of controls. In atrophic gastritis and particularly in Addison-Biermer's disease gastrin level was found to be several times higher. This is probably a result of chronic gastrin secretion stimulation which is normally inhibited by gastric juice. (author)

To determine the management of perforated duodenal ulcer at the University Hospital of the West Indies (UHWI) in this era of Helicobacter pylori, the medical records of all patients seen at the UHWI during the period July 1997 to June 2002 with an intra-operative diagnosis of perforated peptic ulcer were reviewed The records were analyzed for the following: age, gender, duration of symptoms, non-steroidal anti-inflammatory drug (NSAID) use, smoking status, operative repair duration of hospitalization, Helicobacter pylori status and medical therapy, peri-operative complications, mortality and recurrence. Ninety per cent of the cases were males. All females in whom perforation occurred were age 50 years and older compared to males where 58% of cases presented before age 50 years. Perforations in acute ulcers occurred in 80% of cases. The majority of patients were male smokers. Non-steroidal anti-inflammatory drug use was also an important risk factor in elderly females. Simple surgical closure and standard triple therapy antibiotics to eradicate Helicobacter pylori was the most common treatment offered. Mortality was one per cent and follow-up poor but 11% of patients had documented recurrent peptic ulceration. In this study population, perforated duodenal ulcer occured overwhelmingly in males less than 50 years of age. There is a trend towards exclusive simple surgical closure and H pylori eradication at the UHWI for patients with perforated duodenal ulcer but this needs to be supported by documentation of H pylori prevalence in the population of patients presenting with perforated peptic ulcers.

To evaluate if 3 mo oral supplementation with Eviendep® was able to reduce the number of duodenal polyps in familial adenomatous polyposis (FAP) patients with ileal pouch-anal anastomosis (IPAA). Eleven FAP patients with IPAA and duodenal polyps were enrolled. They underwent upper gastrointestinal (GI) endoscopy at the baseline and after 3 mo of treatment. Each patient received 5 mg Eviendep twice a day, at breakfast and dinner time, for 3 mo. Two endoscopists evaluated in a blinded manner the number and size of duodenal polyps. Upper GI endoscopies with biopsies were performed at the baseline (T0) with the assessment of the Spigelman score. Polyps > 10 mm were removed during endoscopy and at the end of the procedure a new Spigelman score was determined (T1). The procedure was repeated 3 mo after the baseline (T2). Four photograms were examined for each patient, at T1 and T2. The examined area was divided into 3 segments: duodenal bulb, second and third portion duodenum. Biopsy specimens were taken from all polyps > 10 mm and from all suspicious ones, defined by the presence of a central depression, irregular surface, or irregular vascular pattern. Histology was classified according to the updated Vienna criteria. At baseline the mean number of duodenal detected polyps was 27.7 and mean sizes were 15.8 mm; the mean Spigelman score was 7.1. After polypectomy the mean number of duodenal detected polyps was 25.7 and mean sizes were 7.6 mm; the mean Spigelman score was 6.4. After 3 mo of Eviendep bid, all patients showed a reduction of number and size of duodenal polyps. The mean number of duodenal polyps was 8 (P = 0.021) and mean size was 4.4 mm; the mean Spigelman score was 6.6. Interrater agreement was measured. Lesions > 1 cm found a very good degree of concordance (kappa 0.851) and a good concordance was as well encountered for smaller lesions (kappa 0.641). Our study demonstrated that short-term (90 d) supplementation with Eviendep® in FAP patients with IPAA

Surgery is the mainstay of treatment of patients with peptic duodenal perforation. With the advent of minimal access techniques, laparoscopy is being used for the treatment of this condition. Retrospective analysis of 120 consecutive patients (mean age 44.5 years; 111 men) with duodenal ulcer perforation who had undergone laparoscopic surgery. 87 patients had history of tobacco consumption, 12 were chronic NSAID users, 72 had Helicobacter pylori infection and 36 had a co-morbid condition. The mean time to surgery from onset of symptoms was 28.4 hours. The median operating time was 46 minutes. All patients underwent laparoscopic closure of the perforation with Graham's patch omentopexy; 12 patients underwent additional definitive ulcer surgery. The morbidity rate was 7.5%; no patient needed conversion to open surgery or died. The mean postoperative hospital stay was 5.8 days. Results of laparoscopic management of perforated peptic ulcer are encouraging, with no conversion to open surgery, low morbidity and no mortality.

Self expandable metallic stent is a good alternative of percutaneous transhepatic biliary drainage because it can eliminate numerous problems caused by external drainage catheter, such as tube dislodgement, bile leakage and psychotic problems. Authors analyzed initial results of self expandable metallic stents used in the patient with malignant biliary obstruction to evaluate the efficacy of the procedure and to find the technical problems in the procedure. Self expandable metallic stents were inserted in 14 patients: three with recurrent stomach cancer: three with gallbladder cancer: seven with Klaskin tumor: one with common duct cancer. Gianturco type stent was used in 9 cases ans Wallstent was used in 2 cases. In remaining three case, both Z-stent and Wallstent were used in the same patient. The average period of follow up was 104 days (4-409 days). In 13 cases, the patency of the bile duct was restored by the stent (technical success: 92.9%). Occlusions of the stent were found in two cases, after two and 13 months, respectively. Causes of failure and stent occlusion were associated duodenal obstruction, tumor overgrowth and shortening of Wallstent. In remaining 11 patients, one patient was lost to follow up an 10 patients did not show recurrent jaundice until death or last follow up. There was no major complication related to the procedure. The insertion of self expandable metallic stent is a safe procedure and can eliminate major disadvantages of PTBD. Overstenting, overlapping and evaluation of associated GI tract obstruction is crucial for obtaining technical success and long-term patency.

Huang-Chi Chen

2008-12-01

Full Text Available Metastatic malignant mesothelioma of the pleura is uncommon at the time of initial diagnosis. The gastrointestinal lumen is rarely found at autopsy in patients with widespread disease. Here, we describe an extremely rare case of isolated duodenal metastasis of sarcomatoid mesothelioma of the pleura in a 73-year-old man, without memory of any direct exposure to asbestos. The possibility of gastrointestinal tract metastasis should be considered in the presence of anemia or positive occult blood test in patients with malignant pleural mesothelioma.

Effect of dopamine-related drugs on duodenal ulcer induced by cysteamine or propionitrile: prevention and aggravation may not be mediated by gastrointestinal secretory changes in the rat

International Nuclear Information System (INIS)

Gallagher, G.; Brown, A.; Szabo, S.

1987-01-01

Dose- and time-response studies have been performed with dopamine agonists and antagonists using the cysteamine and propionitrile duodenal ulcer models in the rat. The experiments demonstrate that the chemically induced duodenal ulcer is prevented by bromocriptine, lergotrile and reduced by apomorphine or L-dopa. Aggravation of cysteamine-induced duodenal ulcer was seen especially after (-)-butaclamol, (-)-sulpiride, haloperidol and, less effectively, after other dopaminergic antagonists. The duodenal antiulcerogenic action of dopamine agonists was more prominent after chronic administration than after a single dose, whereas the opposite was found concerning the proulcerogenic effect of dopamine antagonists. In the chronic gastric fistula rat, both the antiulcerogens bromocriptine or lergotrile and the proulcerogens haloperidol, pimozide or (-)-N-(2-chlorethyl)-norapomorphine decreased the cysteamine- or propionitrile-induced gastric secretion. No correlation was apparent between the influence of these drugs on duodenal ulcer development and gastric and duodenal (pancreatic/biliary) secretions. In the chronic duodenal fistula rat, decreased acid content was measured in the proximal duodenum after haloperidol, and diminished duodenal pepsin exposure was recorded after bromocriptine. Furthermore, the aggravation by dopamine antagonists of experimental duodenal ulcer probably involves a peripheral component. The site of dopamine receptors and physiologic effects which modulate experimental duodenal ulcer remain to be identified, but their elucidation may prove to be an important element in the pathogenesis and treatment of duodenal ulcer

Direct pancreatic function tests (PFTs) are often used to diagnose chronic pancreatitis (CP). We aimed to determine the temporal relationship between an abnormal PFT result, cross-sectional imaging, and clinical symptoms. All patients referred for endoscopic ultrasound (EUS) and PFT for suspected CP at our medical center from 2008 to 2010 were included. Each subject underwent EUS and PFT on the same day using secretin stimulation. Seventeen patients had duodenal HCO3 values of less than 80 mEq/L and were labeled as abnormal; the 25 other patients had at least 1 duodenal HCO3 values of 80 mEq/L or greater. Patients with abnormal PFTs had more parenchymal (2.0 vs 0.92, P = 0.012), ductal (1.18 vs 0.6, P = 0.036), and total features (3.18 vs 1.52, P = 0.009) than those with normal PFTs on EUS examination. There was no difference in regard to the frequency of abnormal CT scans (25% vs 15%, P = 0.139), diarrhea (67% vs 60%, P = 0.463), fat-soluble vitamin deficiency (33% vs 26%, P = 0.315), or diabetes (10% vs 4%, P = 0.066). Patients with equivocal imaging and abnormally low duodenal HCO3 have more EUS features of CP than do patients with normal duodenal HCO3 values, suggesting that low duodenal HCO3 values are among the first measurable abnormalities in CP.

Full Text Available Ectopic adrenocorticotropic hormone (ACTH syndrome is an uncommon disorder and comprises about 15% of all patients with Cushing's syndrome (CS. Duodenal carcinoids are rare, indolent tumors usually associated with a benign progression. We hereby report a rare case of CS resulting from ectopic ACTH secretion from a duodenal neuroendocrine tumor (NET presenting with liver metastasis. A 37-year-old female presented with abdominal discomfort and dyspepsia of 1-month duration. Ultrasound abdomen suggested a well-defined hypoechoic lesion in the left lobe of the liver, suggestive of neoplasia. On clinical examination, she had Cushingoid features and persistent hypokalemia. Midnight ACTH and cortisol levels were grossly elevated at 1027 pg/ml (n < 46 pg/ml and 87.56 μg/dl (n < 7.5 μg/ml, respectively. Both overnight and high-dose dexamethasone suppression test confirmed nonsuppressed cortisol levels - 86.04 and 84.42 μg/dl (n < 1.8 μg/ml, respectively. Magnetic resonance imaging brain showed a structurally normal pituitary gland. Computed tomography scan of the abdomen revealed hepatic lesion with bilateral adrenal enlargement. A diagnosis of ectopic ACTH-dependent CS was made. Intraoperatively, a duodenal lesion of 0.5 cm × 0.5 cm was identified alongside an 8 cm × 6 cm exophytic lesion in segment IV of the liver. Frozen section of the duodenal lesion was positive for NET. She underwent a Whipple's surgery, cholecystectomy, and left hepatic lobectomy. Postoperatively, she showed clinical and biochemical remission. Herewith, we report the third case of duodenal carcinoid tumor presenting as ectopic ACTH syndrome and the first with liver metastasis.

A 7 year old boy was admitted to hospital with gastroenteritis, which was complicated by an acute perforated duodenal ulcer. After oversewing of the perforation he made an uncomplicated recovery. Peptic ulceration is under-diagnosed in childhood and this leads to delay in diagnosis and appropriate management. Ulceration is associated with severe illness and viral infections, but perforation is rare.

2004-01-01

Introduction: Gastro-duodenal perforations may be suspected in patients with history of ulceration, who present with acute pain and abdominal wall rigidity, but radiological findings in these cases may be unable to confirm a clinical diagnosis. The aim of our study was to report our experience in the diagnosis of gastro-duodenal perforation by conventional radiography, US and CT examinations. Material and methods: We retrospectively reviewed medical records of 166 consecutive patients who presented in the last 2 years to our institutions with symptoms of acute abdomen and submitted to surgery at the Emergency Unit of the ''A.Cardarelli'' Hospital of Naples with a surgical finding of perforated gastro-duodenal ulcer. The evidence of free intraperitoneal air on abdominal plain film was considered as a direct or suggestive finding of perforation. Evidence of intraperitoneal free fluid and/or reduced intestinal peristalsis at sonographic examination were considered indirect signs of gastro-duodenal perforation. Evidence of free peritoneal gas at CT was considered as a direct evidence of gastro-duodenal perforation. Results: Twenty patients underwent immediate surgery with no preoperative imaging evaluation, in 10 of them the site of perforation was found in a juxta-pyloric region and in the others at level of duodenum. In 146 patients submitted to serial radiological investigations before surgery, the site of perforation was in 56 (38.3%) duodenal, in 52 (35.6%) juxta-pyloric, in 28 (19.1%) gastric and in 10 (6.8%) pyloric. The cause of perforation was in all cases gastric or duodenal ulceration, in seven cases involving pancreatic parenchyma. In 110 (75.4%) patients with direct findings of perforation, in 94 cases (85.5%) the correct diagnosis was established on abdominal plain film, in two (1.8%) with radiographic and sonographic examinations and in 14 (12.7%) on CT findings. In 36 (24,6%) patients with no direct findings of perforation, only 24 (16,4%) of them

Duodenal perforations during diagnostic upper endoscopy are rare; however, when therapeutic techniques are performed, the reported incidence is as great as 2.8%. Surgical repair is usually mandated, but it is associated with significant morbidity and mortality. To compare closure of duodenal perforations by using an over-the-scope clip (OTSC) with a surgical closure. Randomized, controlled animal study. Animal facility laboratory. Domestic pigs (24 females). Large (10-mm) duodenal perforations were created by using an endoscopic needle-knife. The animals were randomly assigned to either open surgical repair (n=12) or endoscopic closure by using the OTSC system (n=12). Pressurized leak tests were performed during necropsy. One major bleed occurred because of a liver injury during creation of the duodenotomy. Mean time for endoscopic closure was 5 minutes (range, 3-8 min; SD +/- 2). No complications occurred during any of the closure procedures. At necropsy, all OTSC and surgical closures demonstrated complete sealing of duodenotomy sites. Pressurized leak tests demonstrated a mean burst pressure of 166 mm Hg (range, 80-260; SD +/- 65) for OTSC closures and 143 mm Hg (range, 30-300, SD +/- 83) for surgical sutures. Ex vivo intact duodenal specimens exhibited a mean burst pressure of 247 mm Hg (range, 200-300; SD +/- 35), which was significantly higher compared with in vivo OTSC and surgical closures (P < .01). There were no significant differences between burst pressures of OTSC and surgical closures (P = .461). Nonsurvival setting. Endoscopic closure of duodenal perforations by using the OTSC system is comparable with surgical closure in a nonsurvival porcine model. This technique is easy to perform and seems suitable for repairing duodenal perforations. 2010 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc. All rights reserved.

With the development of diagnostic technology, the surgical methods of cancer therapy have been expanded, and operations have been performed using a procedure corresponding to the stage of cancer to improve the postoperative QOL. A 79-year-old man with cancer of the duodenal papilla and obstructive jaundice, and a 63-year-old woman with cholangiocarcinoma in the lower region complicated by cholangitis caused by Candida underwent resections of the pancreatic head and duodenum, and pancreaticogastrostomies retaining the pylorus. Satisfactory results were obtained in both cases. The merits of the procedure were that there were few complaints, sufficient food could be ingested and the QCL was maintained. The benefits of pancreaticogastrostomy are that the anastomosis procedure is simple, the gastric wall is thicker than the jejunum and blood flow is plentiful. The dorsal gastric wall is located close to the pancreatic cut-end, therefore tension is not created, and the pancreatic enzymes are not activated because the anastomosis site does not contact the intestinal fluid. These characteristics should decrease the rate of anastomosis failure which can be a fetal complication. A safer operation is desirable, particularly for elderly patients or patients who have complications.

Endoscopic Management of a Primary Duodenal Carcinoid Tumor

Directory of Open Access Journals (Sweden)

Albin Abraham

2012-03-01

Full Text Available Carcinoids are rare, slow-growing tumors originating from a variety of different neuroendocrine cell types. They are identified histologically by their affinity for silver salts and by positive reactions to neuroendocrine markers such as neuron-specific enolase, synaptophysin and chromogranin. They can present with various clinical symptoms and are difficult to diagnose. We present the case of a 43-year-old woman who was referred for evaluation of anemia. Upper endoscopy showed a duodenal bulb mass around 1 cm in size. Histopathological and immunohistochemistry staining were consistent with the diagnosis of a carcinoid tumor. Further imaging and endoscopic studies showed no other synchronous carcinoid lesions. Endoscopic ultrasound (EUS revealed a 1 cm lesion confined to the mucosa and no local lymphadenopathy. Successful endoscopic mucosal resection of the mass was performed. Follow-up surveillance 6 months later with EUS and Octreoscan revealed no new lesions suggestive of recurrence. No consensus guidelines exist for the endoscopic management of duodenal carcinoid tumors. However, endoscopic resection is safe and preferred for tumors measuring 1 cm or less with no evidence of invasion of the muscularis layer.

Pancreatic trauma is an uncommon injury, occurring in only about 0.2% of blunt abdominal injuries, while duodenal injuries represent approximately 4% of all blunt abdominal injuries. When trauma of the pancreas and duodenum do not permit reparation, pancreatoduodenectomy (PD) is mandatory. In the reconstructive phase, the use of ductal ligation as an alternative to standard pancreaticojejunostomy has been reported by some authors. We report a case of polytrauma with pancreatic and duodenal injury in which the initial diagnosis failed to recognize the catastrophic duodenal and pancreatic situation. The patient was submitted for PD and the pancreatic stump was abandoned in the abdominal cavity after main pancreatic ductal ligation. This technique can minimize the morbidity and mortality of PD in patients with other organs or apparatus involved severely and extensively in trauma.

To evaluate the effects of detomidine on visceral and somatic nociception, heart and respiratory rates, sedation, and duodenal motility and to correlate these effects with serum detomidine concentrations. Nonrandomized, experimental trial. Five adult horses, each with a permanent gastric cannula weighing 534 +/- 46 kg. Visceral nociception was evaluated by colorectal (CRD) and duodenal distension (DD). The duodenal balloon was used to assess motility. Somatic nociception was assessed via thermal threshold (TT). Nose-to-ground (NTG) height was used as a measure of sedation. Serum was collected for pharmacokinetic analysis. Detomidine (10 or 20 microg kg(-1)) was administered intravenously. Data were analyzed by means of a three-factor anova with fixed factors of treatment and time and random factor of horse. When a significant time x treatment interaction was detected, differences were compared with a simple t-test or Bonferroni t-test. Significance was set at p Detomidine produced a significant, dose-dependent decrease in NTG height, heart rate, and skin temperature and a significant, nondose-dependent decrease in respiratory rate. Colorectal distension threshold was significantly increased with 10 microg kg(-1) for 15 minutes and for at least 165 minutes with 20 microg kg(-1). Duodenal distension threshold was significantly increased at 15 minutes for the 20 microg kg(-1) dose. A significant change in TT was not observed at either dose. A marked, immediate decrease in amplitude of duodenal contractions followed detomidine administration at both doses for 50 minutes. Detomidine caused a longer period of visceral anti-nociception as determined by CRD but a shorter period of anti-nociception as determined by DD than has been previously reported. The lack of somatic anti-nociception as determined by TT testing may be related to the marked decrease in skin temperature, likely caused by peripheral vasoconstriction and the low temperature cut-off of the testing device.

Larkin, J O

2012-01-31

INTRODUCTION: Most patients presenting with acutely perforated duodenal ulcer undergo operation, but conservative treatment may be indicated when an ulcer has spontaneously sealed with minimal\\/localised peritoneal irritation or when the patient\\'s premorbid performance status is poor. We retrospectively reviewed our experience with operative and conservative management of perforated duodenal ulcers over a 10-year period and analysed outcome according to American Society of Anesthesiologists (ASA) score. METHODS: The records of all patients presenting with perforated duodenal ulcer to the Department of Surgery, Mayo General Hospital, between January 1998 and December 2007 were reviewed. Age, gender, co-morbidity, ASA-score, clinical presentation, mode of management, operative procedures, morbidity and mortality were considered. RESULTS: Of 76 patients included, 48 (44 operative, 4 conservative) were ASA I-III, with no mortality irrespective of treatment. Amongst 28 patients with ASA-score IV\\/V, mortality was 54.5% (6\\/11) following operative management and 52.9% (9\\/17) with conservative management. CONCLUSION: In patients with a perforated duodenal ulcer and ASA-score I-III, postoperative outcome is uniformly favourable. We recommend these patients have repair with peritoneal lavage performed, routinely followed postoperatively by empirical triple therapy. Given that mortality is equivalent between ASA IV\\/V patients whether managed operatively or conservatively, we suggest that both management options are equally justifiable.

Li Qiang; Li Yiyun; Zhao Chunmei

2011-01-01

Objective: To evaluate the efficacy and feasibility of emergency transcatheter arterial embolization (ETAE) in treating critical massive bleeding due to duodenal bulb ulcer. Methods: ETAE was carried out in seven patients with acute massive bleeding due to endoscopically-proved duodenal bulb ulcer, who failed to respond conservative measures and were critically ill clinically. Super-selective catheterization of gastroduodenal artery or right gastroepiploic artery was performed, which was followed by arterial angiography to identify the bleeding site. According to the angiographic findings, ETAE with Gelfoam particles and coils was carried out. After the operation medical management was given and endoscopy re-examination was conducted. All the patients were follow up for 3∼6 months. Results: Angiographically, gastroduodenal artery bleeding was detected in all seven patients. ETAE was successfully accomplished in all cases. Complete clinical effectiveness was obtained in six patients while partial effectiveness in one case. No procedure-related complications occurred. Conclusion: For critical massive bleeding due to duodenal bulb ulcer ETAE is a highly effective and safe treatment, which can be regarded as an alternative to surgery. It is worth popularizing this technique in clinical practice. (authors)

Spontaneous pneumobilia revealing choledocho-duodenal fistula: A rare complication of peptic ulcer disease

Directory of Open Access Journals (Sweden)

Massimo Tonolini

2013-01-01

Full Text Available Spontaneous pneumobilia without previous surgery or interventional procedures indicates an abnormal biliary-enteric communication, most usually a cholelithiasis-related gallbladder perforation. Conversely, choledocho-duodenal fistulisation (CDF from duodenal bulb ulcer is currently exceptional, reflecting the low prevalence of peptic disease. Combination of clinical data (occurrence in middle-aged males, ulcer history, absent jaundice and cholangitis and CT findings including pneumobilia, normal gallbladder, adhesion with fistulous track between posterior duodenum and pancreatic head allow diagnosis of CDF, and differentiation from usual gallstone-related biliary fistulas requiring surgery. Conversely, ulcer-related CDF are effectively treated medically, whereas surgery is reserved for poorly controlled symptoms or major complications.

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.

Human pancreatico-duodenal injuries caused by camels are extremely rare. We report three patients who sustained camel-related pancreatico-duodenal injuries and review the literature on this topic. A 32-year camel caregiver was kicked by a camel which then stepped on his abdomen trying to kill him. The patient's abdomen was soft and lax. CT scan of the abdomen showed free retroperitoneal air. Laparotomy revealed a complete tear of the anterior wall of the second part of duodenum which was primarily repaired. A 40-year camel caregiver was directly kicked into his abdomen by a camel. He developed traumatic pancreatitis which was treated conservatively. A 31-year-old male fell down on his abdomen while riding a camel. Abdominal examination revealed tenderness and guarding. Abdominal CT Scan showed complete transection of the neck of the pancreas which was confirmed by laparotomy. The patient had distal pancreatectomy with preservation of the spleen. All patients were discharged home in good condition. These cases demonstrate the misleading presentation of the camel-related pancreatico-duodenal injuries and their unique mechanism of injury.

Bile duct-duodenal fistula caused by AIDS/HIV-associated tuberculosis

Directory of Open Access Journals (Sweden)

Patino Carlos

2003-01-01

Full Text Available Allthough infrequent, digestive fistulae in HIV/AIDS patients have been reported throughout the digestive tract from the esophagus to the anus, with predominance of esophageal fistulae. AIDS/HIV-associated opportunistic infections may invade the digestive system and lead to fistula formation. Tuberculosis is the most common infection associated with these esophageal fistulae. We report here one case of bile duct-duodenal fistula in a female AIDS patient with associated abdominal Mycobacterium tuberculosis infection compromising lymphnodes of the hepatic pedicle where the fistula was found. According to the reviewed literature, this is the third case of bile duct-duodenal fistula associated with abdominal tuberculosis in AIDS patient, and the first where both the fistula and the tuberculosis infection were diagnosed at laparotomy for acute abdomen. Whether the AIDS patient with abdominal pain needs or not a laparotomy to treat an infectious disease is often a difficult matter for the surgeon to decide, as most of the times appropriate medical treatment will bring more benefit.

Repair of an Endoscopic Retrograde Cholangiopancreatography-Related Large Duodenal Perforation Using Double Endoscopic Band Ligation and Endoclipping

2017-03-01

Full Text Available Endoscopic closure techniques have been introduced for the repair of duodenal wall perforations that occur during endoscopic retrograde cholangiopancreatography (ERCP. We report a case of successful repair of a large duodenal wall perforation by using double endoscopic band ligation (EBL and an endoclip. Lateral duodenal wall perforation occurred during ERCP in a 93-year-old woman with acute calculous cholangitis. We switched to a forward endoscope that had a transparent band apparatus. A 2.0-cm oval-shaped perforation was found at the lateral duodenal wall. We repaired the perforation by sequentially performing double EBL and endoclipping. The first EBL was performed at the proximal edge of the perforation orifice, and two-thirds of the perforation were repaired. The second EBL, which also included the contents covered under the first EBL, repaired the defect almost completely. Finally, to account for the possible presence of a residual perforation, an endoclip was applied at the distal end of the perforation. The detection and closure of the perforation were completed within 10 minutes. We suggest that double EBL is an effective method for closure.

The presented data demonstrate the frequency and variety of different disorders of mental response to the fact of the disease among patients with duodenal ulcer. It may be seen from experience the doctor's deontology assists essentially to patients in restoring their mental functions disturbed in the period of exacerbation. A psychodiagnostic examination allows detecting patients that require a psychotherapeutic consultation (and a psychiatrist's consultation in a number of cases).

1986-01-01

Chronic gastric and duodenal ulcers may result from ischemia determined by celiac trunk compression stenosis (CTCS). In such cases angiography is necessary to specify diagnosis, to bring to light the causes of ulceration and to define therapeutic tactics. An analysis of angiograms of 75 patients with gastric and duodenal mucosa ulcers in CTCS and its characteristics have presented. The opening and proximal part of the celiac trunk are more frequently subjected to compression. The length of a narrow part of the celiac trunk is on an average of 6.62±0.31 mm. Enlargement in the diameter of the gastroduodenal artery was noted. Simultaneous narrowing of the celaic trunk and the upper mesenteric artery was found in 18 patients

Duodenal ulcers as an abscopal effect of thoracic irradiation in mice

International Nuclear Information System (INIS)

Michalowski, A.; Burgin, J.

1982-01-01

Female CFLP mice irradiated to their thorax with either x-rays or fast neutrons developed peptic ulcers within 8 days of exposure. The steep x-ray dose/response curve for induction of duodenal ulcer gave an ED 50 of approximately 14.5 Gu. As little as 6 Gy of fast neutrons was effective in some cases, but the neutron ED 50 exceeded that for x-rays. The ulcers represented an abscopal effect of thoracic irradiation. Scattered radiation as simulated by whole-body x-ray treatment (1 to 5 Gy) caused a dose-dependent decrease in the frequency of duodenal lesions, possibly by decreasing gastric secretion. The greater amount of scattered radiation accompanying fast neutron exposure of the thorax was presumably responsible for the shallower dose/response curve of ulcer induction than that seen with x-rays

Full Text Available We investigated the effects of feeding diets with different starch sources on fermentation in the rumen, duodenal nutrient flow and nutrient digestibility. The basis of the diets was maize silage and alfalfa hay supplemented with wheat meal in diet W, or maize meal in diet M. The experiment was performed on four Black-Spotted bulls with mean live weight of 525 kg, which were fed twice daily at 06.30 and 18.30 h. Experimental animals were fitted with ruminal fistulae and duodenal T-shaped cannulae. Cr2O3 was used as a marker of nutrient flow to the duodenum. Rations were formulated so that the ratio of starch to crude fibre (CF was 2.1:1 and the percentage of CF was maintained at 17% (DM. Duodenal chymus was collected at 2-h time intervals. Starch origin significantly affected ruminal fermentation. Concentration of propionic, butyric and lactic acid was higher with wheat than with maize meal. When the maize meal was the source of starch there was a significantly higher flow of fat, CF, nitrogen-free extract, and starch into duodenum. Differences in duodenal flow of crude protein were not significant across the starch sources. Intake of wheat meal or maize meal increased duodenal flow relative to intake by 33% or 42 % respectively. The apparent digestibility of dry matter (76 ± 2%, crude protein (67 ± 0.9%, CF (64 ± 1.9%, nitrogen-free extract (82 ± 1.5% and organic matter (76 ± 1.3% was significantly higher by offering wheat meal.

Ursodeoxycholic acid counteracts celecoxib in reduction of duodenal polyps in patients with familial adenomatous polyposis: a multicentre, randomized controlled trial

Science.gov (United States)

2013-01-01

Background Due to prophylactic colectomy, mortality in patients with familial adenomatous polyposis (FAP) has changed, with duodenal cancer currently being the main cause of death. Although celecoxib reduces duodenal polyp density in patients with FAP, its long-term use may increase the risk of cardiovascular events and alternatives need to be explored. Preclinical studies suggest that the combination of celecoxib with ursodeoxycholic acid (UDCA) is a potentially effective strategy. We performed a randomized, double-blind, placebo-controlled trial to investigate the effect of celecoxib and UDCA co-treatment on duodenal adenomatosis in patients with FAP. Methods Patients with FAP received celecoxib (400 mg twice daily) and UDCA (1000-2000 mg daily, ~20-30 mg/kg/day, n=19) or celecoxib and placebo (n=18) orally for 6 months. Primary outcome was drug efficacy, assessed by comparing duodenal polyp density at pre- and post-intervention by blinded review of endoscopic recordings. As secondary outcomes, cell proliferation, apoptosis, and COX-2 levels in normal duodenal mucosa were assessed by immunohistochemistry or real-time quantitative polymerase chain reaction. Results In intention-to-treat analysis, deceased polyp density was observed after celecoxib/placebo treatment (p=0.029), whereas increased polyp density was observed after celecoxib/UDCA treatment (p=0.014). The difference in change in duodenal polyp density was statistically significant between the groups (p=0.011). No changes in secondary outcomes were observed. Thirty patients (81%) reported one or more adverse events, 16 patients (84%, Common Toxicity Criteria for Adverse Events version 3.0 (CTCAE) grade 1–3) treated with celecoxib/UDCA and 14 patients (78%, CTCAE grade 1–2) treated with celecoxib/placebo. Nine patients (24%) discontinued intervention prematurely, 5 patients (26%) treated with celecoxib/UDCA and 4 patients (22%) treated with celecoxib/placebo. Conclusions Celecoxib reduces duodenal

Coeliac disease (CD) has been linked to gastro-oesophageal reflux disease (GORD). Previous studies have demonstrated an increased prevalence of reflux in patients with CD. However data on the risk for CD in patients presenting with reflux are conflicting. The aim of this study was to establish the prevalence of CD in patients with GORD and to elucidate the mechanisms for reflux symptoms in newly diagnosed CD patients. Group A: patients who had undergone routine duodenal biopsy were prospectively recruited between 2004 and 2014. Diagnostic yield was compared with that of a screening cohort. Group B: 32 patients with newly diagnosed CD who had undergone oesophageal manometry and 24-h pH studies were prospectively recruited. Group A: 3368 patients (58.7% female, mean age 53.4 years) underwent routine duodenal biopsy. Of these patients, 850 (25.2%) presented with GORD. The prevalence of CD among GORD patients was 1.3% (0.7-2.4%), which was not significantly higher than that in the general population (P=0.53). Within the context of routine duodenal biopsy at endoscopy (when corrected for concurrent symptoms, age and sex), reflux was found to be negatively associated with CD [adjusted odds ratio 0.12 (0.07-0.23), Preflux. On manometry, 9% had a hypotensive lower oesophageal sphincter and 40.6% had oesophageal motor abnormalities, with 25% significantly hypocontractile. On pH studies, 33% demonstrated reflux episodes. The prevalence of undiagnosed CD among GORD patients is similar to that in the general population, and routine duodenal biopsy cannot be recommended. A significant number of patients with newly diagnosed CD were found to have reflux and/or oesophageal dysmotility on pH/manometry studies; this may explain the high prevalence of reflux symptoms in CD.

The advent of proton pump inhibitors and helicobacter pylori eradication in the management of chronic peptic ulcer disease has reduced the operative treatment of this condition to its complications. Perforated duodenal ulcer remains a major life threatening complication of chronic peptic ulcer disease. This retrospective study reviews our experience at the Royal Victoria Teaching Hospital. All patients with clinical diagnosis of perforated duodenal ulcer seen in this hospital between June 2003 and October 2005 were included in this study. Data extracted from their hospital records were analyzed for age, sex, duration of symptoms, previous history of peptic ulcer disease, use of NSAIDS, main presenting features, investigations, resuscitative measures, time of surgery, operative findings, and type of surgery offered, complications and mortality. After resuscitation, laparotomy followed by simple closure or definitive ulcer surgery and helicobacter pylori eradication therapy was given to all the patients. Duration of follow up ranged 8 to 12 months with endoscopy in some patients. There were 41 patients with intraoperative diagnosis of acute perforated duodenal ulcer seen over the study period, comprising 34 males (82.9%) and 7 females (17.1%), a male female ratio of 4.8:1, age range of 18-77 years and a mean age of 45.49 +/- 14.46 years. Previous history of peptic ulcer disease was found in 32 (78.6%) of the patient and the main presenting features were sudden onset of severe abdominal pain in 95.1% of cases and fever in 65.8%. Features of frank peritonitis were demonstrable in all the patients and 11 (26.8%) presented in shock. Plain chest x-rays demonstrated gas under the diaphragm in 21(65.6%) of the patients. After adequate resuscitation, all the patients underwent laparotomy where the abdomen was explored, the diagnosis of perforated duodenal ulcer was confirmed and 29 (70.7%) had simple closure of the perforation with omentum (after Graham).

Motor-evacuatory stomach function by using continuous radiogastrography was studied in patients with duodenal ulcers. Radiogastrograms were analyzed before operation, on the 7th-15th day after selective proximal vagotomy performed either independently or in combination with draining operations. A faster evacuation of food from the stomach prevailed in an uncomplicated form of duodenal ulcer and compensated stenosis of the pyloroduodenal zone, evacuatory stomach function was retarded or absent in subcompensated and decompensated stenosis. Discoordinated gastric peristalsis and a reverse food input were noted in patients with subcompensated stenosis. At early time after operations temporary inhibition of evacuatory stomach function occurred in 94.2% of the patients; it could be corrected with conservative therapeutic measures.

2002-06-01

Full Text Available Abstract Background Bouveret's syndrome is an unusual presentation of duodenal obstruction caused by the passage of a large gallstone through a cholecystoduodenal fistula. Endoscopic therapy has been used as first-line treatment, especially in patients with high surgical risk. Case presentation We report a 67-year-old woman who underwent an endoscopic attempt to fragment and retrieve a duodenal stone using a Holmium: Yttrium-Aluminum-Garnet Laser (Ho:YAG which resulted in small bowel obstruction. The patient successfully underwent enterolithotomy without cholecystectomy or closure of the fistula. Conclusion We conclude that, distal gallstone obstruction, due to migration of partially fragmented stones, can occur as a possible complication of laser lithotripsy treatment of Bouveret's syndrome and might require urgent enterolithotomy.

Gastro-duodenal perforations are common and may complicate peptic ulcer disease. Management is often by surgical closure. To determine the patterns of presentation and mode of management of duodenal ulcer perforations. Retrospective review of patients with duodenal ulcer perforations seen at the Obafemi Awolowo University Teaching Hospital between June 2001 and July 2011. Patients' records were reviewed for demography, duration of disease, probable risk factors, type of surgery and complications. Data obtained was analyzed using SPSS 15.0. Forty- five patients were reviewed. There were 37 males (82.2%). Mean age was 39.7years (range 15-78years). There were 10 (22.6%) students and 8(17.8%) farmers. NSAIDs abuse (11), previous peptic ulcer disease (2), and no prior dyspeptic symptoms (20) constituted 24.4%, 4.4% and 44.4% respectively of cases. Seven (16%) patients presented less than 24 hours of onset of illness. Forty one perforations (91.1%) involved the first part of duodenum. Twenty two (49%) patients had Graham's omental patch. We had one (2.2%) failed repair and six (13.3%) mortalities. Late presentation of duodenal ulcer perforation is common with high mortality. Pragmatic surgical intervention with Graham's omentopexy with broad spectrum antibiotics is still commonly practiced.

The body concentration of iron is regulated by a fine equilibrium between absorption and losses of iron. Iron can be absorbed from diet as inorganic iron or as heme. Hemopexin is an acute phase protein that limits iron access to microorganisms. Moreover, it is the plasma protein with the highest binding affinity for heme and thus it mediates heme-iron recycling. Considering its involvement in iron homeostasis, it was postulated that hemopexin may play a role in the physiological absorption of inorganic iron. Hemopexin-null mice showed elevated iron deposits in enterocytes, associated with higher duodenal H-Ferritin levels and a significant increase in duodenal expression and activity of heme oxygenase. The expression of heme-iron and inorganic iron transporters was normal. The rate of iron absorption was assessed by measuring the amount of (57)Fe retained in tissues from hemopexin-null and wild-type animals after administration of an oral dose of (57)FeSO4 or of (57)Fe-labelled heme. Higher iron retention in the duodenum of hemopexin-null mice was observed as compared with normal mice. Conversely, iron transfer from enterocytes to liver and bone marrow was unaffected in hemopexin-null mice. The increased iron level in hemopexin-null duodenum can be accounted for by an increased iron uptake by enterocytes and storage in ferritins. These data indicate that the lack of hemopexin under physiological conditions leads to an enhanced duodenal iron uptake thus providing new insights to our understanding of body iron homeostasis.

THE USE OF THE FORCEPS BIOPSY AS AN AUXILIARY TECHNIQUE FOR THE VISUALIZATION OF THE MAJOR DUODENAL PAPILLA USING THE FOWARD-VIEWING UPPER ENDOSCOPY

Directory of Open Access Journals (Sweden)

Nathalia Saber de ANDRADE

Full Text Available ABSTRACT BACKGROUND: - Conventional esophagogastroduodenoscopy is the best method for evaluation of the upper gastrointestinal tract, but it has limitations for the identification of the major duodenal papilla, even after the use of the straightening maneuver. Side-viewing duodenoscope is recommended for optimal examination of major duodenal papilla in patients at high risk for lesions in this region. OBJECTIVE: To evaluate the use of the biopsy forceps during conventional esophagogastroduodenoscopy as an additional tool to the straightening maneuver, in the evaluation of the major duodenal papilla. METHODS: A total of 671 patients were studied between 2013 and 2015, with active major duodenal papilla search in three endoscope steps: not straightened, straightened and use of the biopsy forceps after straightening. In all of them it was recorded whether: major duodenal papilla was fully visualized (position A, partially visualized (position B or not visualized (position C. If major duodenal papilla was not fully visualized, patients continued to the next step. RESULTS: A total of 341 were female (50.8% with mean age of 49 years. Of the 671 patients, 324 (48.3% major duodenal papilla was identified in position A, 112 (16.7% in position B and 235 (35% in position C. In the 347 patients who underwent the straightening maneuver, position A was found in 186 (53.6%, position B in 51 (14.7% and position C in 110 (31.7%. Of the 161 remaining patients and after biopsy forceps use, position A was seen in 94 (58.4%, position B in 14 (8.7% and position C in 53 (32.9%. The overall rate of complete visualization of major duodenal papilla was 90%. CONCLUSION: The use of the biopsy forceps significantly increased the total major duodenal papilla visualization rate by 14%, reaching 604/671 (90% of the patients (P<0.01 and it can be easily incorporated into the routine endoscopic examination of the upper gastrointestinal tract.

Retrospective analysis of gastro-duodenal bleeding (GDB report forms was performed. Pts admitted to the department of internal diseases of Saratov regional clinical hospital from 1999 to 2004 were included. 354 cases of GDB were recorded ( 282 from 1999 to 2001 and 72 from 2002 to 2004. Cause ofbleeding, influence of NSAID administration on appearance and relapse ofbleeding, source ofbleeding and pt management were assessed. NSAJD administration was considered trigger factor of GDB in 24% in 1999-2001 and in 18% in 2002-2004. The results of the study show some tendency to decrease of NSAID- induced gastropathy frequency among causes of GDB. The main risk factors ofbleeding during NSAID treatment were age of more than 30 years, ulcer history, the first month of NSAID administration. GDB frequency did not depend on regularity of treatment and NSAID dosage.

Bynum, T E; Koch, G G

We sought to compare the efficacy of sucralfate to placebo for the prevention of duodenal ulcer recurrence and to determine that the efficacy of sucralfate was due to a true reduction in ulcer prevalence and not due to secondary effects such as analgesic activity or accelerated healing. This was a double-blind, randomized, placebo-controlled, parallel groups, multicenter clinical study with 254 patients. All patients had a past history of at least two duodenal ulcers with at least one ulcer diagnosed by endoscopic examination 3 months or less before the start of the study. Complete ulcer healing without erosions was required to enter the study. Sucralfate or placebo were dosed as a 1-g tablet twice a day for 4 months, or until ulcer recurrence. Endoscopic examinations once a month and when symptoms developed determined the presence or absence of duodenal ulcers. If a patient developed an ulcer between monthly scheduled visits, the patient was dosed with a 1-g sucralfate tablet twice a day until the next scheduled visit. Statistical analyses of the results determined the efficacy of sucralfate compared with placebo for preventing duodenal ulcer recurrence. Comparisons of therapeutic agents for preventing duodenal ulcers have usually been made by testing for statistical differences in the cumulative rates for all ulcers developed during a follow-up period, regardless of the time of detection. Statistical experts at the United States Food and Drug Administration (FDA) and on the FDA Advisory Panel expressed doubts about clinical study results based on this type of analysis. They suggested three possible mechanisms for reducing the number of observed ulcers: (a) analgesic effects, (b) accelerated healing, and (c) true ulcer prevention. Traditional ulcer analysis could miss recurring ulcers due to an analgesic effect or accelerated healing. Point-prevalence analysis could miss recurring ulcers due to accelerated healing between endoscopic examinations. Maximum ulcer

Sucralfate is a basic aluminium salt of sucrose octasulphate which has been used in the treatment of peptic ulcers already for several years. Sucralfate administrated orally, coats selectively areas of ulceration, both gastric and duodenal, providing protection against acids and other irritants. The protective layer probably consists of sucralfate-protein complexes in the ulcerated areas. (orig.)

Periodontal disease has been associated with higher circulating levels of inflammatory markers and conditions associated with chronic inflammation, including vascular disease, diabetes mellitus, and cancer. Limited data exist on the relationship between periodontal disease and gastric and duodenal ulcer. We conducted a prospective cohort study of 49,120 men in the Health Professionals Follow-up Study, aged 40-75 years at enrollment in 1986. Biennially, we assessed periodontal disease, tooth loss, and other risk factors for gastric and duodenal ulcer. We validated diagnoses of gastric and duodenal ulcer through medical record review. We used Cox proportional hazards modeling, adjusting for potential confounders, to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). We documented 138 cases of gastric ulcer and 124 cases of duodenal ulcer with available information on Helicobacter pylori status over 24 years of follow-up. After adjustment for risk factors, including smoking and regular use of aspirin and non-steroidal anti-inflammatory drugs, men with periodontal disease with bone loss had a multivariate HR of ulcer of 1.62 (95% CI, 1.24-2.12). Periodontal disease appeared to be associated with a similar risk of developing ulcers that were H. pylori negative (HR 1.75; 95% CI, 1.26-2.43) than H. pylori positive (HR 1.40; 95% CI, 0.87-2.24), as well as ulcers in the stomach (HR 1.75; 95% CI, 1.21-2.53) than ulcers in the duodenum (HR 1.47; 95% CI, 0.98-2.19). Periodontal disease is associated with an increased risk of incident gastric and duodenal ulcer. This relationship may be mediated by alterations in the oral and gastrointestinal microbiome and/or systemic inflammatory factors.

2017-06-01

Full Text Available Background: Helminths sometimes require surgical or endoscopic intervention. Helminths may cause acute abdomen, mechanical intestinal obstruction, gastrointestinal hemorrhage, perforation, hepatitis, pancreatitis, and appendicitis. This study aimed to determine the surgical diseases that helminths cause and to gather, analyze the case reports, case series and original articles about this topic in literature.Methods: This study was designed as a retrospective observational study. In order to determine the studies published in literature, the search limits in PubMed database were set to 1 Jan 1957 and 31 Mar 2016 (59 yr, and the articles regarding Helminth-Surgery-Endoscopy were taken into examination. Among 521 articles scanned, 337 specific ones were involved in this study.Results: The most common surgical pathology was found to be in Ascaris lumbricoides group. Enterobius vermicularis was found to be the parasite that caused highest amount of acute appendicitis. Anisakiasis was observed to seem mainly because of abdominal pain and mechanical intestinal obstruction. Strongyloides stercoraries causes duodenal pathologies such as duodenal obstruction and duodenitis. Taenia saginata comes into prominence with appendicitis and gastrointestinal perforations. Fasciola hepatica exhibits biliary tract involvement and causes common bile duct obstruction. Hookworms were observed to arise along with gastrointestinal hemorrhage and anemia. Trichuris trichiuria draws attention with gastrointestinal hemorrhage, mechanical intestinal obstruction.Conclusion: Helminths may lead to life-threatening clinic conditions such as acute abdomen, gastrointestinal perforation, intestinal obstruction, and hemorrhages. There is a relationship between surgery and helminths. It is very important for surgeons to consider and remember helminths in differential diagnoses during their daily routines.

Identification of a disease-specific H pylori virulence factors predictive of the outcome of infection remains unachieved. We used the polymerase chain reaction and Southern blot to compare the presence of 14 vir homologue genes with clinical presentation of H pylori infection, mucosal histology, and mucosal interleukin (IL)-8 levels. We examined 500 H pylori strains from East Asia and South America, including 120 with gastritis, 140 with duodenal ulcer (DU), 110 with gastric ulcer (GU), and 130 with gastric cancer. Only 1 gene that encompassed both jhp0917 and jhp0918 called dupA (duodenal ulcer promoting gene) was associated with a specific clinical outcome. dupA was present in 42% of DU vs. 21% of gastritis (adjusted odds ratio [OR] = 3.1, 95% confidence interval [CI]: 1.7-5.7). Its presence was also associated with more intense antral neutrophil infiltration and IL-8 levels and was a marker for protection against gastric atrophy, intestinal metaplasia, and gastric cancer (OR for gastric cancer = 0.42, 95% CI: 0.2-0.9 compared with gastritis). In vitro studies in gastric epithelial cells using dupA -deleted and -complemented mutants showed that the dupA plays roles in IL-8 production, in activation of transcription factors responsible for IL-8 promoter activity, and in increased survivability at low pH. dupA is a novel marker associated with an increased risk for DU and reduced risk for gastric atrophy and cancer. Its association with DU-promoting and -protective effects against atrophy/cancer was evident in both Asian and Western countries.

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.

This study investigated if the H. pylori dupA genotype and certain host single nucleotide polymorphisms (SNPs) of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs), including MMP-3, MMP-7, MMP-9, TIMP-1 and TIMP-2, might correlate with ulcer risk of H. pylori-infected Taiwanese patients. Of the 549 H. pylori-infected patients enrolled, 470 patients (265 with gastritis, 118 with duodenal ulcer, and 87 with gastric ulcer) received SNPs analysis of MMP-3-1612 6A > 5A, MMP-7-181 A > G, MMP-9exon 6 A > G, TIMP-1372 T > C and TIMP-2-418 G > C by PCR-RFLP. The 181 collected H. pylori isolates were detected for the dupA genotype by PCR. The rates of dupA-positive H. pylori infection were similar among patients with duodenal ulcer (22.8%), gastric ulcer (20.0%), and gastritis (25.5%) (p > 0.05). Males had higher rates of duodenal ulcer and gastric ulcer than females (p dupA-status, may correlate with susceptibility to duodenal ulcer after H. pylori infection in Taiwanese females.

Full Text Available CONTEXT: Intestinal parasites induce detectable histopathological changes, which have been studied in groups with known diagnosis of parasitic disease. There is no available study with a larger base without previous diagnosis. OBJECTIVE: To describe clinical and histopathological findings of parasitosis diagnosed by endoscopic biopsy in patients submitted to upper digestive endoscopy. METHODS: Recorded biopsies archive at "Complexo Hospitalar Professor Edgar Santos" , a general teaching Hospital in the state of Bahia, Northeast Brazil, from January 1995 to January 2009, were reviewed. One thousand ten duodenal biopsy reports were found. Reports positive for parasites had their specimens reviewed and photographed. All blocks of biopsy selected as case were retrieved and reviewed by an experienced pathologist. Clinical, laboratorial and endoscopic data were collected. RESULTS: Eleven biopsies showed parasites, including cases of Cryptosporidium sp. and Strongyloides stercoralis. Vomiting (91%, abdominal pain (78%, diarrhea (78% and weight loss (78% were usual symptoms. Seventy-five percent had duodenal mucosa changes on endoscopy, while 25% have no changes. Anemia and low serum albumin were important laboratorial data. HIV infection association was observed. Villus atrophy and reactive epithelium were usual in Strongyloides cases. CONCLUSIONS: No endoscopic or histopathologic finding was pathognomonic. One percent of duodenal endoscopic biopsies showed parasites.

Duodenal duplication cysts are rare congenital abnormalities which are more commonly diagnosed in infancy and childhood. However, in rare cases, these lesions can remain asymptomatic until adulthood. The combination of duplication cyst and pancreas divisum is extremely rare and both conditions have been linked with acute recurrent pancreatitis. We present the case of a 37 years-old patient who presented with repeated episodes of acute pancreatitis. By means of magnetic resonance imaging and endoscopic ultrasonography we discovered a duplication cyst whose cavity received drainage from the dorsal pancreas. After opening the cyst cavity to the duodenal lumen with a needle knife the patient presented no further episodes in the clinical follow-up. Comparable literature findings and therapeutic options for these abnormalities are discussed with regard to the presented case. PMID:21160764

International Nuclear Information System (INIS)

Nomani, A.Z.; Qureshi, M.S.

2014-01-01

Objective: To identify prognostic factors for perforated duodenal ulcers and to devise and assess a new scoring system. Methods: The observational prospective study was conducted at the Mayo Hospital, Lahore in two phases: from March 2010 to September 2011; and from October 2011 to July 2012. It included patients with duodenal ulcer perforation who were observed for identifying factors predicting 30-day prognosis. Each of the predictive factor was given a score based on its severity to devise a new scoring system. Chi-square was used for univariate analysis. Multivariate analysis was done using forward stepwise regression. Accuracy of the new scoring system was calculated using receiver operating curve analysis and its validity was evaluated in the second phase of the study. Results: Predictors of poor prognosis included multiple gut perforations, size of largest perforation >0.5cm, amount of peritoneal fluid >1000ml, simple closure, development of complications, post-operative systemic septicaemia and winter/autumn season of presentation. Overall 30-day mortality rate was 32.3% (n=32) and morbidity rate was 21.2% (n=21). The mean score was higher in the ones with poor prognosis (p=0.001). Similarly, the mean score was greater in those with grave prognosis (p=0.001). The scoring system had an overall sensitivity of 85.12% and specificity of 80.67% and was favourably comparable to other scoring systems. Conclusion: The new scoring system is a useful tool in predicting 30-day prognosis for perforated duodenal ulcers in acid peptic disease. (author)

To evaluate current evidence for a causal relation between Helicobacter pylori infection and gastritis, duodenal ulcer, gastric cancer and nonulcer dyspepsia. A MEDLINE search for articles published in English between January 1983 and December 1992 with the use of MeSH terms Helicobacter pylori, gastritis, duodenal ulcer, gastric cancer, dyspepsia and clinical trial; abstracts were excluded. Six journals and Current Contents were searched manually for pertinent articles published in that time frame. Original studies with at least 25 patients, case reports and reviews that examined the relation between H. pylori and the four gastrointestinal disorders; 350 articles were on gastritis, 122 on duodenal ulcer, 44 on gastric cancer and 96 on nonulcer dyspepsia. The quality of the studies was rated independently on a four-point scale. The strength of the evidence was assessed using a six-point scale for each of the eight established guidelines for determining a causal relation. There was conclusive evidence of a causal relation between H. pylori infection and histologic gastritis. Koch's postulates for the identification of a microorganism as the causative agent of a disease were fulfilled for H. pylori as a causative agent of gastritis. There was strong evidence that H. pylori is the main cause of duodenal ulcers not induced by nonsteroidal anti-inflammatory drugs, but all of Koch's postulates were not fulfilled. There was moderate epidemiologic evidence of an association between chronic H. pylori infection and gastric cancer. There was a lack of convincing evidence of a causal association between H. pylori and nonulcer dyspepsia. The evidence supports a strong causal relation between H. pylori infection and gastritis and duodenal ulcer and a moderate relation between such infection and gastric cancer. Further studies are needed to clarify the role of H. pylori in these disorders. Thus far, there is no evidence of a causal relation between H. pylori and nonulcer

Full Text Available Even though the seroprevalence of H. pylori may be high in the normal population, a minority develops peptic ulcer. Colonization of the gastric mucosa by more pathogenic vacA strains of H. pylori seems to be associated with enhanced gastric inflammation and duodenal ulcer. H. pylori genotyping from positive CLOtests was developed to determine the vacA genotypes and cagA status in 40 duodenal ulcer patients and for routine use. The pathogenic s1b/ m1/ cagA genotype was the most frequently occurring strain (17/42.5%; only two (5% patients presented the s2/ m2 genotype, the less virulent strain. Multiple strains were also detected in 17 (42.5% patients. Multiple strains of H. pylori colonizing the human stomach have been underestimated, because genotyping has been performed from cultures of H. pylori. We concluded that genotyping of H. pylori from a positive CLOtest had the advantages of reducing the number of biopsies taken during endoscopy, eliminating the step of culturing H. pylori, and assuring the presence of H. pylori in the specimen being processed.

This study assessed the influence of tumor localization of small bowel adenocarcinoma on survival after surgical resection. Patients with resected small bowel adenocarcinoma, ACJJ stage I-III, were identified from the Surveillance, Epidemiology, and End Results database from 2004 to 2013. The impact of tumor localization on overall and cancer-specific survival was assessed using Cox proportional hazard regression models with and without risk-adjustment and propensity score methods. Adenocarcinoma was localized to the duodenum in 549 of 1025 patients (53.6%). There was no time trend for duodenal localization (P = 0.514). The 5-year cancer-specific survival rate was 48.2% (95%CI: 43.3-53.7%) for patients with duodenal carcinoma and 66.6% (95%CI: 61.6-72.1%) for patients with cancer located in the jejunum or ileum. Duodenal localization was associated with worse overall and cancer-specific survival in univariable (HR = 1.73; HR = 1.81, respectively; both P matrimonial status were positive, independent prognostic factors. Duodenal localization is an independent risk factor for poor survival after resection of adenocarcinoma. © 2017 Wiley Periodicals, Inc.

The endogenous DNA adducts O(6)-carboxymethyl-deoxyguanosine (O(6)-CM-dG) and 3-ethanesulfonic acid-deoxycytidine (3-ESA-dC) are produced from N-nitroso bile acid conjugates, such as N-nitrosoglycocholic acid (NO-GCA) and N-nitrosotaurocholic acid (NO-TCA), respectively. Formation of these DNA adducts in vivo was here analyzed by 32P-postlabeling in the glandular stomach of rats subjected to duodenal content reflux surgery. In this model, all duodenal contents, including bile acid conjugates, flow back from the jejunum into the gastric corpus. The levels of O(6)-CM-dG found at 4 and 8 weeks after surgery were 40.9 +/- 9.4 and 56.3 +/- 3.2 per 10(8) nucleotides, respectively, whereas the sham operation groups had values of 5.8 +/- 2.3 and 5.9 +/- 0.5 per 10(8) nucleotides. Moreover, adduct spots corresponding to 3-ESA-dC were detected in both duodenal reflux and sham operation groups and levels in the duodenal reflux groups were around four-fold elevated at 11.2 +/- 1.0 and 8.9 +/- 1.0 per 10(8) nucleotides after 4 and 8 weeks, respectively. When the duodenal reflux animals were treated with a nitrite trapping agent, thiazolidine- 4-carboxylic acid (thioproline, TPRO), the levels of O(6)-CM-dG and 3-ESA-dC were reduced to the same levels as in the sham operation animals. These observations suggest that NO-TCA and NO-GCA are formed by nitrosation of glycocholic acid and taurocholic acid, respectively, and these nitroso compounds produce DNA adducts in the glandular stomach of rats subjected to duodenal content reflux surgery.

BACKGROUND:Emergency physicians(EPs)often care for patients with acute small bowel obstruction.While some patients require exploratory laparotomy,others are managed successfully with supportive care.We aimed to determine features that predict the need for operative management in emergency department(ED)patients with small bowel obstruction(SBO).METHODS:We performed a retrospective chart review of 370 consecutive patients admitted to a large urban academic teaching hospital with a diagnosis of SBO over a two-year period.We evaluated demographic characters(prior SBO,prior abdominal surgery,active malignancy)and clinical findings(leukocytosis and lactic acid)to determine features associated with the need for urgent operative intervention.RESULTS:Patients with a prior SBO were less likely to undergo operative intervention[20.3%(42/207)]compared to those without a prior SBO[35.2%(57/162)].Abnormal bloodwork was not associated with need for operative intervention.68%of patients with CT scan findings of both an SBO and a hernia,however,were operatively managed.CONCLUSIONS:Patients with a history of SBO were less likely to require operative intervention at any point during their hospitalization.Abnormal bloodwork was not associated with operative intervention.The CT finding of a hernia,however,predicted the need for operative intervention,while other findings(ascites,duodenal thickening)did not.Further research would be helpful to construct a prediction rule,which could help community EPs determine which patients may benefit from expedited transfer for operative management,and which patients could be safely managed conservatively as an initial treatment strategy.

Duodenal acid infusion induces gastric relaxation and sensitization to distension in healthy volunteers. The acid-sensitive mechanism is still unknown. We hypothesized that 5HT(3)-blockade can inhibit the acid-induced duodenogastric sensorimotor reflex in healthy volunteers. Fourteen healthy volunteers were included in a randomized, double-blind placebo-controlled cross-over trial. An infusion tube with attached pH-electrode was positioned in the duodenum and a barostat balloon was located in the gastric fundus. Proximal gastric volume and sensitivity to distension were assessed before and during duodenal acid infusion and after pretreatment with intravenous (i.v.) ondansetron (a 5HT(3)-receptor antagonist, 8 mg) or saline. An overall perception score (0-6) and an assessment of nine dyspeptic symptoms by visual analogue scales (VAS) were obtained. Results are given as mean ± SEM. Ondansetron had no effect on duodenal pH and on the acid-induced increase of proximal gastric volume (increase of 80 ± 20 vs 83 ± 15 mL after ondansetron and placebo; effect of acid acid infusion and gastric distension. 5HT(3)-receptors are involved in acid-induced duodenogastric sensitization, but not in the duodenogastric inhibitory motor reflex. © 2010 Blackwell Publishing Ltd.

2009-01-01

Many patients with malignant gastroduodenal obstruction have an unresectable primary lesion and distant metastases, which may prompt palliative management to allow the patient to eat and to improve the quality of life. Intraluminal metallic stent implantation (MSI) under fluoroscopic guidance has been reported to be an effective option for symptomatic relief in these patients, with a good safety record. An alternative, dual interventional therapy (DIT), has been used during the last decade, in which prosthesis insertion is followed by intra-arterial chemotherapy via the tumor-feeding arteries. The aim of this study was to compare success rates, complication rates, and survival time between MSI and DIT in patients who presented with gastroduodenal obstruction from advanced upper gastrointestinal tract cancer. All consecutive patients with malignant gastroduodenal obstruction seen at our center between October 2002 and August 2007 were retrospectively studied. Patients were treated palliatively by either MSI or DIT by the patient's or the next of kin's decision. Outcomes included technical and clinical success, complication rates, and survival. Of the 164 patients with malignant gastric and duodenal outlet obstructions, 80 (49%) underwent stent insertion as the primary therapy, while the remaining 84 (51%) received DIT. Clinical characteristics were similar between the two groups. In the MSI cohort initial stent implantation was successful in 73 patients (91%), two stents were used in 5 patients, and delayed additional stent insertion for stent obstruction related to tumor overgrowth was required in 3 patients during follow-up. In the DIT cohort the technical success rate was 94%, 3 patients required two stents, and stent obstruction occurred in 2 patients after initial stent placement. Early postprocedural clinical success, indicated by average dysphagia score, improved significantly in both groups: MSI group, from 4.56 to 1.51 (P < 0.01); and DIT group, from 4

Full Text Available OBJETIVOS: Apresentar a experiência dos autores no tratamento do pâncreas anular, comparando os dados com os da literatura. MÉTODOS: É relatada a experiência do Departamento de Cirurgia Geral do Hospital de Clínicas de Porto Alegre em pâncreas anular com a descrição de quatro pacientes. A doença manifestou-se em três faixas etárias distintas: uma no período neonatal, outra na infância e duas na fase adulta. O quadro clínico de obstrução intestinal alta esteve presente em três dos quatro pacientes. Dor abdominal foi queixa constante entre os adultos. A investigação diagnóstica foi realizada através do estudo contrastado do estômago e duodeno, da endoscopia digestiva e da tomografia abdominal. A confirmação diagnóstica somente foi possível durante a laparotomia. A derivação duodenal foi a técnica cirúrgica empregada em dois casos e a ressecção do tecido pancreático nos pacientes adultos. RESULTADOS: Os quatros pacientes evoluíram favoravelmente no período pós-operatório. O tempo de internação hospitalar variou de 9 a 12 dias, com média de 10,5 dias. Não houve complicação cirúrgica e todos os pacientes permanecem assintomáticos em acompanhamento ambulatorial. CONCLUSÃO: A raridade desta anomalia não permite um estudo mais detalhado e comparativo. Os resultados aqui apresentados como os encontrados na literatura demonstram que a derivação duodenal e a ressecção pancreática são alternativas eficazes e seguras quando bem indicadas.PURPOSE: To present the authors experience managing anular pancreas and to compare the results found by the authors with the ones foundin the literature.

Large bowel obstruction may present as an emergency as high-grade colonic obstruction and can result in perforation. Perforated large bowel obstruction causes faecal peritonitis, which can result in high morbidity and mortality. Multidetector row computed tomography (MDCT) has the potential of providing an accurate diagnosis of large bowel obstruction. The rapid acquisition of images within one breath-hold reduces misregistration artefacts than can occur in critically ill or uncooperative patients. The following is a review of the various causes of large bowel obstruction with emphasis on important pathogenic factors, CT appearances and the use of multiplanar reformatted images in the diagnostic workup.

Full Text Available Tissue transglutaminase (tTG is a ubiquitous multifunctional protein. It has roles in various cellular processes. tTG is a major target of autoantibodies in celiac disease, and its expression by immunohistochemistry in pediatric celiac disease has not been fully examined. We studied tTG expression in 78 pediatric duodenal biopsies by utilizing an antibody to transglutaminase 2. Serum tTG was positive in all celiac cases evaluated. Serum antiserum endomysial antibody (EMA and tTG were negative in all control subjects and in inflammatory bowel disease and eosinophilic gastroenteritis. There was a statistically significant difference between cases of celiac disease and normal controls in terms of tTG immunohistochemical staining in duodenal biopsies surface epithelium ( value = 0.0012. There was no significant statistical difference in terms of staining of the villous surface or crypt between the cases of celiac disease and cases with IBD ( value = 0.5970 and 0.5227, resp.. There was no detected correlation between serum tTG values and immunohistochemical positivity on duodenal biopsy in cases of celiac disease ( value = 1. There was no relationship between Marsh classification and positivity of villous surface for tTG ( value = 0.4955.

Purpose Little information is available on genetic and epigenetic changes in duodenal adenocarcinomas. The purpose was to identify possible subsets of duodenal adenocarcinomas based on microsatellite instability (MSI), DNA methylation, mutations in the KRAS and BRAF genes, clinicopathologic features, and prognosis. Experimental Design Demographics, tumor characteristics and survival were available for 99 duodenal adenocarcinoma patients. Testing for KRAS and BRAF mutations, MSI, MLH1 methylation and CpG island methylator phenotype (CIMP) status was performed. A Cox proportional hazard model was built to predict survival. Results CIMP+ was detected in 27 of 99 (27.3%) duodenal adenocarcinomas, and was associated with MSI (P = 0.011) and MLH1 methylation (P CIMP− tumors. No BRAF V600E mutation was detected. Among the CIMP+ tumors, 15 (55.6%) were CIMP+/MLH1-unmethylated (MLH1-U). Kaplan-Meier analysis showed tumors classified by CIMP, CIMP/MLH1 methylation status or CIMP/MSI status could predict overall survival (OS; P = 0.047, 0.002, and 0.002, respectively), while CIMP/MLH1 methylation status could also predict time-to-recurrence (TTR; P = 0.016). In multivariate analysis, CIMP/MLH1 methylation status showed a significant prognostic value regarding both OS (P CIMP+/MLH1-U tumors had the worst OS and TTR. Conclusions Our results demonstrate existence of CIMP in duodenal adenocarcinomas. The combination of CIMP+/MLH1-U appears to be independently associated with poor prognosis in patients with duodenal adenocarcinomas. This study also suggests that BRAF mutations are not involved in duodenal tumorigenesis, MSI or CIMP development. PMID:22825585

In order to determine the effects of intraoperative radiation therapy of the bile duct and surrounding tissues, seven adult dogs were subjected to laparotomy and intraoperative irradiation with 11 MeV electrons. Two animals were treated at each dose level of 2000, 3000, and 4500 rads. A single dog which received a laparotomy and sham irradiation served as a control. The irradiation field consisted of a 5 cm diameter circle encompassing the extrahepatic bile duct, portal vein, hepatic artery, and lateral duodenal wall. The animals were followed clinically for mor than 18 months after treatment, and autopsies were performed on dogs that died to assess radiation-induced complications or tissue damage. All dogs developed fibrosis and mural thickening of the common duct, which appeared by 6 weeks following irradiation and which was dose-related, being mild at low doses and more severe at high doses. Hepatic changes were seen as early as 6 weeks after irradiation, consisting of periportal inflammation and fibrosis. The hepatic changes appeared earliest at the highest doses. Frank biliary cirrhosis eventually developed at all dose levels. Duodenal fibrosis appeared in the irradiation portal, being most severe at the highest doses and in some animals resulting in duodenal obstruction. No changes were observed in irradiated portions of portal vein and hepatic artery at any dose level. It was concluded that intraoperative radiation therapy delivered to the region of the common duct leads to ductal fibrosis, partial biliary obstruction with secondary hepatic changes, and duodenal fibrosis if bowel wall is included in the field. Clinical use of intraoperative radiation therapy to the bile duct in humans may require routine use of biliary and duodenal bypass to prevent obstructive complications

Successful Management of Perforated Duodenal Diverticulitis With Intra-abdominal Drainage and Feeding Jejunostomy: A Case Report and Literature Review

Full Text Available We report the clinical experience of one patient with perforated duodenal diverticulitis who was successfully treated by intra-abdominal drainage and feeding jejunostomy. A 53-year-old male patient visited our hospital due to acute onset of abdominal pain and distension. Physical examination revealed tenderness over the epigastric area and right-lower quadrant of the abdomen without obvious rebound tenderness or muscle guarding. Duodenal diverticulitis with a retroperitoneal abscess was identified by abdominal computed tomography scan. Surgical intervention was performed after the failure of conservative treatment. The operative findings were compatible with perforated duodenal diverticulitis, and intra-abdominal drainage of retroperitoneal abscess with simultaneous feeding jejunostomy was undertaken. The patient was doing well at the 4-month postoperative follow-up visit. We suggest the use of a conservative operative method, as opposed to conventional diverticulectomy and duodenorrhaphy, as an alternative approach for the management of this disorder, especially when conservative treatment has failed.

Study with the purpose to examine the effects of duodenal switch (DS), regularly performed in morbidly obese patients, on biodistribution of sodium pertechnetate in several organs of rats. There was no early or late mortality in either rats groups. The values of percent radioactivity per gram of tissue (%ATI/g), showed no significant difference in liver, stomach, small bowel, duodenum, kidney, heart, bladder, bone and brain, when compared the DS rats with sham and controls rats. A postoperative significant increase (p<0.05) in mean %ATI/g levels was observed in spleen, pancreas and muscle in group DS rats, as compared to group S and C rats. In the lung there was an increase and in thyroid a decrease in mean %ATI/g of DS rats, when compared to sham rats (p<0.05). In conclusion, the biliopancreatic diversion with duodenal switch in rats modified the biodistribution of sodium pertechnetate in thyroid, lung, pancreas, spleen and muscle. (author)

Celiac disease is a common disorder with a worldwide distribution, although the prevalence among different ethnicities varies. We aimed to measure the prevalence of duodenal villous atrophy among patients of different ethnicities throughout the United States. We performed a cross-sectional study of all patients who had duodenal biopsies submitted to a national pathology laboratory between January 2, 2008 and April 30, 2015. The prevalence of villous atrophy was calculated for the following ethnicities by using a previously published algorithm based on patient names: North Indian, South Indian, East Asian, Hispanic, Middle Eastern, Jewish, and other Americans. Among all patients (n = 454,885), the median age was 53 years, and 66% were female. The overall prevalence of celiac disease was 1.74%. Compared with other Americans (n = 380,163; celiac disease prevalence, 1.83%), celiac disease prevalence was lower in patients of South Indian (n = 177, 0%; P = .08), East Asian (n = 4700, 0.15%; P ≤ .0001), and Hispanic (n = 31,491, 1.06%; P ≤ .0001) ethnicities. Celiac disease was more common in patients from the Punjab region (n = 617, 3.08%) than in patients from North India (n = 1195, 1.51%; P = .02). The prevalence of celiac disease among patients of Jewish (n = 17,806, 1.80%; P = .78) and Middle Eastern (n = 1903, 1.52%; P = .33) ethnicities was similar to that of other Americans. Among Jewish individuals (n = 17,806), the prevalence of celiac disease was 1.83% in Ashkenazi persons (n = 16,440) and 1.39% in Sephardic persons (n = 1366; P = .24). Among patients undergoing duodenal biopsy, individuals from the Punjab region of India constitute the ethnic group in the United States with the highest prevalence of villous atrophy consistent with celiac disease. Compared with other Americans, villous atrophy prevalence on duodenal biopsy is significantly lower among U.S. residents of South Indian, East Asian, and Hispanic ancestry. Copyright © 2016 AGA

Previous structure-activity and pharmacologic studies with duodenal ulcerogens cysteamine and propionitrile implicating catecholamines in the pathogenesis of duodenal ulceration have now been followed up by dose- and time-response biochemical investigations to assess the importance of monoamines in the development of duodenal ulcers. The concentrations of norepinephrine (noradrenaline), dopamine, serotonin and their metabolites were measured in total brain, brain regions, stomach, duodenum, pancreas and adrenals in the rat. Turnover of catecholamines was determined in rats pretreated with the inhibitor of tyrosine hydroxylase alpha-methyl-p-tyrosine. The duodenal ulcerogens caused a dose- and time-dependent depletion of norepinephrine in virtually all the tissues examined. The effect was maximal 4 or 7 hr after cysteamine or propionitrile, and norepinephrine levels returned to normal in 24 hr. Dopamine changes were selective and often biphasic, e.g., elevation in adrenals, biphasic in brain cortex, hippocampus and midbrain, but uniformly decreasing in glandular stomach and duodenum. In the median eminence dopamine levels decreased by 181 and 324% at 15 and 30 min, respectively, after cysteamine, but neither dopamine nor 3,4-dihydroxyphenylacetic acid was modified in the periventricular nucleus. Serotonin levels were relatively stable, revealing slight elevations or no changes in most of the tissues. The turnover of norepinephrine was accelerated by both chemicals in virtually all brain regions, but dopamine turnover was affected only in a few areas, e.g., in the corpus striatum and medulla oblongata cysteamine decreased dopamine turnover, whereas propionitrile first (at 1 hr) accelerated then (at 8 hr) significantly suppressed it.(ABSTRACT TRUNCATED AT 250 WORDS)

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

The purpose of the present study was to compare gastric emptying in two groups of dogs in which a gastrojejunal or duodenojejunal Roux-en-Y anastomosis was performed over the site of an experimental obstruction in the distal duodenum. The experiment was carried out on 10 mongrel dogs. Gastric emptying was assessed twice in each dog before the experiment (control examination); the solid phase of the test meal was labelled with 99mTc. Following a control examination, the dogs were divided into two groups of 5 animals each, and subjected to the above mentioned surgical procedures. Postoperative gastric emptying was carried out 3 weeks after the operation, and then at 3 and 6 months following the procedure. The following parameters describing quantitatively gastric emptying were determined: mean transit time MTT0-60. MTT0-120 and total mean transit time MTT0-180. The comparison of these parameters revealed statistically significant differences confirming delay of gastric emptying in dogs with a gastrojejunal anastomosis.

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

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

With the continuous improvement of liver transplantation technology, the survival rate of liver transplantation has been improved, but recurrent or de novo malignancy remains one of the major factors affecting the long-term survival of liver transplant recipients. A 45-year-old Chinese man had a plastic biliary stent placed on account of biliary anastomotic stenosis after 3 years of piggyback liver transplantation. He came to our hospital because of recurrent fever and jaundice for 2 weeks, and his carcinoembryonic antigen-199 had increased. The patient's duodenal papillary was cauliflower-like at endoscopic retrograde cholangiopancreatography to replace the biliary stent. He was initially suspected of having duodenal papillary carcinoma after liver transplantation. However, the pathology from endoscopic retrograde cholangiopancreatography and endoscopic ultrasound-guided biopsy showed inflammation. While awaiting the result of biopsy, his CA-199 decreased significantly after anti-infection and symptomatic treatment. The patient was diagnosed with biliary anastomotic stenosis and duodenal papillitis. He was discharged uneventfully; to date, there is no evidence of malignant tumor. We report this case to provide helpful information to clinicians about the management of the duodenal papilla cauliflower-like neoplasm after liver transplantation, which should be considered as inflammatory first. Perhaps our view can avoid the risk of bringing an excessive medical treatment and unnecessary economic burden to patients and their families. Copyright © 2018 Elsevier Inc. All rights reserved.

2006-09-01

Full Text Available Abstract Echocardiography is a valuable non-invasive technique for identifying the site and type of aortic obstruction. Knowledge of the morphological details of each type of obstruction is the basis for correct interpretation of the diagnostic images and clinical decisions. This study was undertaken to correlate the echocardiographic images with anatomic specimens of equivalent valvular and supravalvular aortic obstruction. Specimens were part of the collection of the Department of Embryology. Fifty six patients were studied, and forty specimens with aortic obstruction were analyzed. Echocardiographic characteristics: Thirty one (55.3% patients were women and twenty five (44.7% men. Valvular aortic obstruction was found in Thirty six patients (64.3 % and supravalvular aortic obstruction in twenty (35.7%. Anatomic characteristics: Of the forty specimens examined, twenty one (52.5% had valvular aortic obstruction and nineteen (47.5% supravalvular aortic obstruction. The anatomoechocardiographic correlation clearly showed that the anatomic findings of the specimen hearts and aortas corresponded to echocardiographic images of valvular and supravalvular aortic obstruction and provided solid corroboration of echocardiographic diagnoses.

Acute GI obstruction.

Acute gastrointestinal obstruction occurs when the normal flow of intestinal contents is interrupted. The blockage can occur at any level throughout the gastrointestinal tract. The clinical symptoms depend on the level and extent of obstruction. Various benign and malignant processes can produce acute gastrointestinal obstruction, which often represents a medical emergency because of the potential for bowel ischemia leading to perforation and peritonitis. Early recognition and appropriate treatment are thus essential. The typical clinical symptoms associated with obstruction include nausea, vomiting, dysphagia, abdominal pain and failure to pass bowel movements. Abdominal distention, tympany due to an air-filled stomach and high-pitched bowel sounds suggest the diagnosis. The diagnostic process involves imaging including radiography, ultrasonography, contrast fluoroscopy and computer tomography in less certain cases. In patients with uncomplicated obstruction, management is conservative, including fluid resuscitation, electrolyte replacement, intestinal decompression and bowel rest. In many cases, endoscopy may aid in both the diagnostic process and in therapy. Endoscopy can be used for bowel decompression, dilation of strictures or placement of self-expandable metal stents to restore the luminal flow either as a final treatment or to allow for a delay until elective surgical therapy. When gastrointestinal obstruction results in ischemia, perforation or peritonitis, emergency surgery is required. Copyright © 2013. Published by Elsevier Ltd.

Duodenal atresia in an infant with triple-X syndrome: a new associated malformation in 47,XXX.

2007-08-01

An association between the triple-X syndrome (47,XXX) and gastrointestinal malformations is extremely rare. Most 47,XXX patients present with a normal phenotype, but genitourinary malformations have been described. We report a case of a child with 47,XXX and duodenal atresia. Antenatal ultrasound scan showed a dilated fetal stomach and upper part of the duodenum (double bubble phenomenon) at 31 weeks of gestation in a 31-year-old woman with polyhydramnion. The amniotic fluid karyotype showed 47,XXX. After a scheduled delivery, duodenal atresia was confirmed and treated with duodeno-duodenostomy. The possible association of gastrointestinal and genitourinary tract anomalies requires a detailed postnatal clinical investigation and ultrasonographic examination of the abdomen, retroperitoneum, and pelvis on all triple-X syndrome patients. 2007 Wiley-Liss, Inc.

2014-01-01

Full Text Available Gastrointestinal carcinoid tumors are uncommon neuroendocrine tumours that may be associated with synchronous or metachronous primary tumours of other histological type, most frequently colorectal adenocarcinomas. Primary ovarian mucinous adenocarcinomas have been reported to coincide with few other ovarian tumours and minority of these tumours may occur in association with Lynch syndrome. However association of duodenal carcinoid with ovarian mucinous adenocarcinoma is distinctly unusual and, to our knowledge, has not been previously described. We report a case of occult metastasising duodenal atypical carcinoid that was incidentally detected during surgical intervention performed for left ovarian mucinous cystadenocarcinoma in a middle aged female. The carcinoid tumour was Stage IIIB with regional nodal metastasis and the ovarian tumour was Stage IA with low grade histology.

Zhao Ming; Wu Hua; Huang Zhihua

1996-01-01

The purpose of this study was to develop an effective diagnostic method for infantile jaundice. 99m Tc-EHIDA hepatobiliary scintigraphy and determination of bilixanthine from duodenal drainage were carried out in 33 infants with persistent jaundice. The final diagnosis was confirmed by surgical operation, pathology or clinical follow-up. For diagnosing biliary atresia, the sensitivity and specificity of scintigraphy were 100% and 72.7% respectively and those of bilixanthine measurement were 100% and 95.5%. Hepatobiliary scintigraphy may be a sensitive, simple, safe and noninvasive method for differentiating infantile jaundice. Duodenal bilixanthine determination may improve the specificity in the case without intestinal radioactivity in scintigram

Increasing apoA-I synthesis may improve HDL functionality and lower CVD risk. As theobromine and fat increase fasting apoA-I concentrations, and the intestine is involved in apoA-I production, the acute effects of both were studied on duodenal gene transcription to better understand underlying mechanisms. In this crossover study, 8 healthy men received once a low fat (LF) meal, a LF meal plus theobromine (850 mg), or a high fat (HF) meal. Five hours after meal intake duodenal biopsies were taken for microarray analysis. Theobromine and HF consumption did not change duodenal apoA-I expression. Theobromine did not change gene expression related to lipid and cholesterol metabolism, whereas those related to glycogen/glucose breakdown were downregulated. HF consumption increased gene expression related to lipid and cholesterol uptake and transport, and to glucose storage, while it decreased those related to glucose uptake. Furthermore, genes related to inflammation were upregulated, but inflammation markers in plasma were not changed. In healthy men, acute theobromine and fat consumption did not change duodenal apoA-I mRNA, but inhibited expression of genes related to glucose metabolism. Furthermore, HF intake activated in the duodenum expression of genes related to lipid and cholesterol metabolism and to inflammation.

Bile salt-induced increases in duodenal brush-border membrane proton permeability, fluidity, and fragility

Zhao, D.L.; Hirst, B.H.

1990-01-01

Rabbit duodenal brush-border membrane vesicles were treated in vitro with deoxycholate, glycodeoxycholate, or taurodeoxycholate. Intravesicular [14C]glucose space at equilibrium, 0.54 microliters/mg protein, was reduced by exposure to the three bile salts in a concentration (0.1-5.0 mM)-dependent manner, equatable with increased membrane fragility. Net proton permeability (Pnet), determined by acridine orange fluorescence quenching, was increased from 6.3 x 10(-4) cm/sec in untreated vesicles, by approximately 120, 150, and 170%, by treatment with bile salts at 0.1, 0.5 and 1.0 mM, respectively. The three bile salts were equipotent. The increases in membrane fragility and Pnet were not accompanied by significant increases in membrane fluidity, as assessed from steady-state and time-resolved diphenylhexatriene fluorescence anisotropy. The data demonstrate direct effects of bile salts on duodenal apical membrane fragility and proton permeability that are likely to be early events in bile salt-induced mucosal damage

To postoperative endoscopic retrograde cholangiopancreatography (ERCP) failure, we describe a modified Rendezvous technique for an ERCP in patients operated on for common bile duct stone (CBDS) having a T-tube with retained CBDSs. Five cases operated on for CBDSs and having retained stones with a T-tube were referred from other hospitals located in or around Istanbul city to the ERCP unit at the Haydarpasa Numune Education and Research Hospital. Under sedation anesthesia, a sterile guide-wire was inserted via the T-tube into the common bile duct (CBD) then to the papilla. A guide-wire was held by a loop snare and removed through the mouth. The guide-wire was inserted into the sphincterotome via the duodenoscope from the tip to the handle. The duodenoscope was inserted down to the duodenum with a sphincterotome and a guide-wire in the working channel. With the guidance of a guide-wire, the ERCP and sphincterotomy were successfully performed, the guide-wire was removed from the T-tube, the stones were removed and the CBD was reexamined for retained stones by contrast. An ERCP can be used either preoperatively or postoperatively. Although the success rate in an isolated ERCP treatment ranges from up to 87%-97%, 5%-10% of the patients require two or more ERCP treatments. If a secondary ERCP fails, the clinicians must be ready for a laparoscopic or open exploration. A duodenal diverticulum is one of the most common failures in an ERCP, especially in patients with an intradiverticular papilla. For this small group of patients, an antegrade cannulation via a T-tube can improve the success rate up to nearly 100%. The modified Rendezvous technique is a very easy method and increases the success of postoperative ERCP, especially in patients with large duodenal diverticula and with intradiverticular papilla.

Association of chronic obstructive pulmonary disease and obstructive sleep apnea consequences

This coexistence is known as overlap syndrome and is the result of chance rather than a pathophysiological link. Although there are claims of a very high incidence of OSAS in COPD patients, recent studies report that it is similar to the general population. Overlap patients present sleep-disordered breathing associated to upper and lower airway obstruction and a reduction in respiratory drive. These patients present unique characteristics, which set them apart from either COPD or OSAS patients. COPD and OSAS are independent risk factors for cardiovascular events and their coexistence in overlap syndrome probably increases this risk. The mechanisms underlying cardiovascular risk are still unclear, but may involve systemic inflammation, endothelial dysfunction, and tonic elevation of sympathetic neural activity. The treatment of choice for overlap syndrome in stable patients is CPAP with supplemental oxygen for correction of upper airway obstructive episodes and hypoxemia during sleep.Keywords: chronic obstructive pulmonary disease, obstructive sleep apnea syndrome, overlap syndrome, sleep, cardiovascular disease

2015-07-01

Recent work has suggested that within-breath respiratory impedance measurements performed using the forced oscillation technique may help to noninvasively evaluate respiratory mechanics. We investigated the influence of airway obstruction on the within-breath forced oscillation technique in smokers and chronic obstructive pulmonary disease patients and evaluated the contribution of this analysis to the diagnosis of chronic obstructive pulmonary disease. Twenty healthy individuals and 20 smokers were assessed. The study also included 74 patients with stable chronic obstructive pulmonary disease. We evaluated the mean respiratory impedance (Zm) as well as values for the inspiration (Zi) and expiration cycles (Ze) at the beginning of inspiration (Zbi) and expiration (Zbe), respectively. The peak-to-peak impedance (Zpp=Zbe-Zbi) and the respiratory cycle dependence (ΔZrs=Ze-Zi) were also analyzed. The diagnostic utility was evaluated by investigating the sensitivity, the specificity and the area under the receiver operating characteristic curve. ClinicalTrials.gov: NCT01888705. Airway obstruction increased the within-breath respiratory impedance parameters that were significantly correlated with the spirometric indices of airway obstruction (R=-0.65, pdisease patients presented significant expiratory-inspiratory differences (p90%). We conclude the following: (1) chronic obstructive pulmonary disease introduces higher respiratory cycle dependence, (2) this increase is proportional to airway obstruction, and (3) the within-breath forced oscillation technique may provide novel parameters that facilitate the diagnosis of respiratory abnormalities in chronic obstructive pulmonary disease.

Full Text Available The high prevalence of the pathology of major duodenal papilla in patients with gallstone disease, the difficulties of diagnosis and treatment determine the relevance of the study. The purpose is to study the morphological features of the major duodenal papilla in patients with cholelithiasis. Material and methods. During autopsies, selection of fragments of major duodenal papilla from 30 dead was performed. The main group consisted of autopsy specimens (n = 15 from the dead, which had stones in the gallbladder in the absence of signs of inflammation of the walls of the gallbladder and bile ducts. Biomaterial samples (n = 15 from the dead, which had no stones and signs of inflammation of the biliary system, were included in the control group. To study the severity of the stromal component, the Mason’s trichrome and the Van Gieson’s stains were used. Light microscopy was carried out using a light microscope Axioplan 2 (Carl Zeiss - Germany using x10, x20, x40, x100 lenses and x10 eyepiece. For a quantitative assessment of the severity of sclerotic changes, we conducted a morphometric study of preparations stained with picrofuchsin accordimg to Van Gieson. The area of the stromal component was calculated in the resulted images in 5 fields of view under magnification of x200 using the medical software for analysis and processing of digital images ImageJ, initiated by W. Rasband (1997-2012. The expression area was the percentage ratio of the number of pixels of the digital image of the zones of expression of the connective tissue component to the total number of pixels in the image. Results. The quantitative analysis of the severity of sclerotic changes in the periductal tissue in both studied groups showed that in the control observations the expression area of the connective tissue component was 18.84 ± 3.14%, and in the main group (cases of gallstone disease – 78.06 ± 15.12% (p = 0.0031. Conclusions. 1. In patients with gallstone disease

Full Text Available Epithelial tumors less commonly occur in the duodenum than in the stomach or large intestine. The clinicopathological characteristics of duodenal epithelial tumors remain a matter of debate. We therefore studied resected specimens to investigate the clinicopathological characteristics of duodenal epithelial tumors.Among duodenal epithelial tumors resected endoscopically or surgically in our hospital, we studied the clinicopathological characteristics of 110 adenomas or intramucosal carcinomas. The grade of atypia of all tumors was classified into 3 groups according to the World Health Organization (WHO 2010 classification. The tumors were immunohistochemically evaluated to determine the frequency of differentiation toward fundic glands.As for patient characteristics, there were 76 men (75.2% and 25 women (24.8%, with a median age of 65 years (range, 34 to 84. The tumors most commonly arose in the first to second part of the duodenum. Many lesions were flat, and the median tumor diameter was 8.0 mm. The lesions were classified into 2 types according to mucin phenotype: intestinal-type tumors (98 lesions, 89.1% and gastric-type tumors (12 lesions, 10.9%. Intestinal-type tumors were subdivided into 2 groups: tubular-type tumors (91 lesions, 82.7% and tubulovillous-type tumors (7 lesions, 6.4%. Gastric-type tumors were classified into 2 types: foveolar type (3 lesions, 2.7% and pyloric gland-type (PG tumors (9 lesions, 8.2%. The grade of atypia was significantly higher in gastric-type tumors (p<0.01. PG tumors were gastric-type tumors characterized by pyloric glands and findings suggesting differentiation toward fundic glands.About 10% of the duodenal tumors had a gastric-type mucin phenotype. Gastric-type tumors showed high-grade atypia. In particular, PG tumors showed similarities to PG tumors of the stomach, such as differentiation toward fundic glands.

Benign duodenal neoplasm is a rare occurrence. Minimally invasive tumor resection and anastomosis formation with an OrVil catheter is a novel approach to treating this disease. In this article, we present a new technique for duodenojejunal anastomosis. This technique was applied in 4 patients with benign distal duodenal tumors who were treated with minimally invasive surgery with robotic assistance. In 4 patients, after the removal of distal duodenal masses with a robotic technique, an orifice in the duodenum was opened to allow for the passage of a guidewire. The guidewire was removed from the orifice by holding it with forceps during an upper endoscopy. An OrVil catheter was sutured to the guidewire outside to allow 2 catheters to proceed consecutively. After the removal of the anvil, an end-lateral duodenojejunostomy was performed with a circular stapler. The patients included 3 men and 1 woman (average age, 56). The durations of the operations were 215, 175, 180, and 185 minutes. No complications were observed in any of the patients during the postoperative period. The patients began oral intake on the fifth day of the postoperative period, and they were discharged on the sixth postoperative day. Histopathologic analyses indicated that the removed tumors were adenomas in 2 patients and gastrointestinal stromal tumors (GISTs) in 2 patients. Clear surgical margins were observed in all of the patients. The placement of an OrVil catheter for anastomosis in benign neoplasms with distal duodenum localization and the subsequent achievement of duodenojejunal anastomosis with a circular stapler constitute a novel treatment approach.

Full Text Available The role of iron transport proteins in the pathogenesis of anemia in patients with diabetes mellitus (T2DM is still unclear. We investigated the expression of duodenal transporter proteins in diabetic patients with and without iron deficiency anemia (IDA. Methods. Overall, 39 patients were included: 16 with T2DM and IDA (group A, 11 with T2DM without IDA (group B, and 12 controls (group C. Duodenal mucosal expression of divalent metal transporter 1 (DMT1, ferroportin 1 (FPN, hephaestin (HEPH, and transferrin receptor 1 (TfR was evaluated by Western blotting. Chronic disease activity markers were measured as well. Results. FPN expression was increased in group A compared to group B and controls: 1.17 (0.72–1.46, 0.76 (0.53–1.04, and 0.71 (0.64–0.86, respectively (p=0.011. TfR levels were over expressed in groups A and B compared to controls: 0.39 (0.26–0.61, 0.36 (0.24–0.43, and 0.18 (0.16–0.24, respectively, (p=0.004. The three groups did not differ significantly with regard to cellular HEPH and DMT1 expression. The normal CRP and serum ferritin levels, accompanied with normal FPN among diabetic patients without IDA, do not support the association of IDA with chronic inflammatory state. Conclusion. In patients with T2DM and IDA, duodenal iron transport protein expression might be dependent on body iron stores rather than by chronic inflammation or diabetes per se.

Purpose: To characterize the rates of acute and late duodenal and other gastrointestinal (GI) toxicities among patients treated for cervical and endometrial cancers with extended-field intensity modulated radiation therapy (EF-IMRT) to the paraaortic nodes and to analyze dose-volume relationships of GI toxicities. Methods and Materials: Fifty-three patients with endometrial or cervical cancer underwent EF-IMRT to the paraaortic nodes, of whom 46 met the inclusion criteria for GI toxicity and 45 for duodenal toxicity analysis. The median prescribed dose to the paraaortic nodes was 54 Gy (range, 41.4-65 Gy). The 4 duodenal segments, whole duodenum, small bowel loops, peritoneum, and peritoneum plus retroperitoneal segments of colon were contoured retrospectively, and dosimetric analysis was performed to identify dose-volume relationships to grade ≥3 acute (<90 day) and late (≥90 day) GI toxicity. Results: Only 3/46 patients (6.5%) experienced acute grade ≥3 GI toxicity and 3/46 patients (6.5%) experienced late grade ≥3 GI toxicity. The median dose administered to these 6 patients was 50.4 Gy. One of 12 patients who received 63 to 65 Gy at the level of the renal hilum experienced grade 3 GI toxicity. Dosimetric analysis of patients with and without toxicity revealed no differences between the mean absolute or fractional volumes at any 5-Gy interval between 5 Gy and the maximum dose. None of the patients experienced duodenal toxicity. Conclusions: Treatment of paraaortic nodes with IMRT is associated with low rates of GI toxicities and no duodenal-specific toxicity, including patients treated with concurrent chemotherapy. This technique may allow sufficient dose sparing of the bowel to enable safe dose escalation to at least 65 Gy.

Possible mechanisms underlying diabetes remission following Roux-en-Y gastric bypass (RYGB) include eradication of putative factor(s) with duodenal-jejunal bypass. The objective of this study is to observe the effects of duodenal-jejunal transit on glucose tolerance and diabetes remission in gastric bypass rat model. In order to verify the effect of duodenal-jejunal transit on glucose tolerance and diabetes remission in gastric bypass, 22 type 2 diabetes Sprague-Dawley rat models established through high-fat diet and low-dose streptozotocin (STZ) administered intraperitoneally were assigned to one of three groups: gastric bypass with duodenal-jejunal transit (GB-DJT n = 8), gastric bypass without duodenal-jejunal transit (RYGB n = 8), and sham (n = 6). Body weight, food intake, blood glucose, as well as meal-stimulated insulin, and incretin hormone responses were assessed to ascertain the effect of surgery in all groups. Oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were conducted three and 7 weeks after surgery. Comparing our GB-DJT to the RYGB group, we saw no differences in the mean decline in body weight, food intake, and blood glucose 8 weeks after surgery. GB-DJT group exhibited immediate and sustained glucose control throughout the study. Glucagon-like peptide 1 (GLP-1) and gastric inhibitory polypeptide (GIP) levels were also significantly increased from preoperative level in the GB-DJT group (p transit does not impede glucose tolerance and diabetes remission after gastric bypass in type-2 diabetes Sprague-Dawley rat model.

To investigate and compare the efficacy and safety of percutaneous transhepatic biliary stenting (PTBS) using a one- or two-stage procedure and determine the predictive factors for the efficacious treatment of malignant hilar obstruction (MHO). 159 consecutive patients with MHO who underwent PTBS were enrolled between January 2010 and June 2013. Patients were classified into one- or two-stage groups. Independent predictors of therapeutic success were evaluated using a logistic regression model. 108 patients were treated with one-stage PTBS and 51 patients were treated with two-stage PTBS. The stents were technically successful in all patients. Successful drainage was achieved in 114 patients (71.4 %). A total of 42 early major complications were observed. Re-interventions were attempted in 23 patients during follow-up. The cumulative primary patency rates at 3, 6, and 12 months were 88, 71, and 48 %, respectively. Stent placement using a one- or two-stage procedure did not significantly affect therapeutic success, early major complications, median stent patency, or survival. A stent placed across the duodenal papilla was an independent predictor of therapeutic success (odds ratio = 0.262, 95 % confidence interval [0.107-0.642]). Patients with stents across papilla had a lower rate of cholangitis compared with patients who had a stent above papilla (7.1 vs. 20.3 %, respectively, p = 0.03). The majority of patients with MHO who underwent one-stage PTBS showed similar efficacy and safety outcomes compared with those who underwent two-stage PTBS. Stent placement across the duodenal papilla was associated with a higher therapeutic success rate.

In obstructive sleep apnea (OSA), airway obstruction occurs at different anatomic levels. The frequency and location of obstructions play a crucial role in the planning of surgical treatment. The aim of this study was to evaluate the pharyngeal obstruction levels in different sleep stages with manometry in OSA patients. In addition, the manometry results were compared with drug-induced sleep endoscopy (DISE). Forty-one patients with OSA received manometry measurements during one night of sleep. All patients were simultaneously evaluated with polysomnography. The frequency of obstructions in different sleep stages was assessed. Twenty patients were additionally studied with DISE. Obstruction levels detected with manometry were compared with DISE. The frequency of upper and to a lesser extent lower obstructions decreased in sleep stage N3. In rapid eye movement (REM) sleep, lower obstructions increased. The overall proportion of upper and lower obstructions detected with manometry corresponded with DISE in 13 of 20 cases. A significant change in the obstruction levels was detected with manometry in N3 and REM sleep. The reduction of both upper and to a lesser extent lower obstructions in N3 suggests more stable airways in slow-wave sleep. Relevant lower obstructions were not detected in DISE compared to manometry in 5 out of 20 examinations. This could be a potential reason for treatment failure of site-specific surgical OSA treatment when only performing DISE preoperatively. Therefore, manometry could be a useful complementary tool in the preoperative evaluation for OSA.

The efficacy of low-dose lansoprazole has not been established for the prevention of recurrent gastric or duodenal ulcers in those receiving long-term low-dose aspirin (LDA) for cardiovascular and cerebrovascular protection. This study sought to examine the efficacy of low-dose lansoprazole (15 mg once daily) for the secondary prevention of LDA-associated gastric or duodenal ulcers. Patients were randomized to receive lansoprazole 15 mg daily (n = 226) or gefarnate 50 mg twice daily (n = 235) for 12 months or longer in a prospective, multicenter, double-blind, randomized active-controlled trial, followed by a 6-month follow-up study with open-label lansoprazole treatment. The study utilized 94 sites in Japan and 461 Japanese patients with a history of gastric or duodenal ulcers who required long-term LDA therapy for cardiovascular and cerebrovascular disease. The primary endpoint was the development of gastric or duodenal ulcers. The cumulative incidence of gastric or duodenal ulcers on days 91, 181, and 361 from the start of the study was calculated by the Kaplan-Meier method as 1.5, 2.1, and 3.7%, respectively, in the lansoprazole group versus 15.2, 24.0, and 31.7%, respectively, in the gefarnate group. The risk of ulcer development was significantly (log-rank test, P lansoprazole group than in the gefarnate group, with the hazard ratio being 0.099 (95% confidence interval [CI] 0.042-0.230). Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term LDA therapy.

Full Text Available Background Foreign body ingestion is a relatively common in children. Most ingested foreign bodies spontaneously pass out of the body via the gastrointestinal (GI system but sharp materials may perforate the GI tract and need to surgical intervention. Case Presentation  The patient was a 9-year-old girl with progressive abdominal pain for one month and admitted with acute abdomen impression. She underwent esogastroduodenoscopy (EGD due to severe epigastric tenderness. Upper GI endoscopy revealed duodenal ulceration and perforation by a toothpick while she had no history of foreign body ingestion. Toothpick was removed by endoscopy. She was successfully managed conservatively and had no abdominal pain during the one month follow-up period. Conclusion We recommend the endoscopic approach as the preferable method for the extraction of duodenal foreign bodies in children, even in the case of intestinal perforation.

Current classifications of Chronic Obstructive Pulmonary Disease (COPD) severity are complex and do not grade levels of obstruction. Obstruction is a simpler construct and independent of ethnicity. We constructed an index of obstruction severity based on the FEV 1 /FVC ratio, with cut-points dividing the Burden of Obstructive Lung Disease (BOLD) study population into four similarly sized strata to those created by the GOLD criteria that uses FEV 1 . We measured the agreement between classifications and the validity of the FEV 1 -based classification in identifying the level of obstruction as defined by the new groupings. We compared the strengths of association of each classification with quality of life (QoL), MRC dyspnoea score and the self-reported exacerbation rate. Agreement between classifications was only fair. FEV 1 -based criteria for moderate COPD identified only 79% of those with moderate obstruction and misclassified half of the participants with mild obstruction as having more severe COPD. Both scales were equally strongly associated with QoL, exertional dyspnoea and respiratory exacerbations. Severity assessed using the FEV 1 /FVC ratio is only in moderate agreement with the severity assessed using FEV 1 but is equally strongly associated with other outcomes. Severity assessed using the FEV 1 /FVC ratio is likely to be independent of ethnicity.

The syndrome of intestinal pseudo-obstruction is a complex of signs and symptoms of intestinal obstruction without evidence of mechanical obstruction of the intestinal lumen. A patient with radiation-induced intestinal pseudoobstruction is described. The patient is a 74-year old woman with a history of chronic diarrhea, recurrent episodes of crampy abdominal pain, nausea and vomiting since receiving a 13,000 rad radiation dose to the pelvis in 1954. She has been hospitalized on many occasions for symptoms and signs of bowel obstruction. Upper gastrointestinal contrast roentgenograms with small bowel follow-through done during these episodes revealed multiple dilated loops of small bowel with no obstructing lesion. Barium enemas revealed no obstructing lesion. Each episode resolved with conservative therapy. Other secondary causes for intestinal pseudo-obstruction were ruled out in our patient. She gave no history of familial gastrointestinal disorders. Although postirradiation motility abnormalities have been demonstrated experimentally this is the first report of radiation induced intestinal pseudo-obstruction

Effective medical management of peptic ulcer disease (PUD) has reduced the incidence of gastric outlet obstruction (GOO) as a complication, but perforation especially in the elderly remains unchanged and is in fact on the increase. There is a changing trend in emergency surgery for perforated duodenal ulcer (PDU) from definitive anti ulcer surgery to simple closure followed by Helicobacter pylori eradication. To present our experience in managing PDU with simple closure followed by Helicobacter pylori eradication. This was a chart review of patients managed for PDU over a nine year period (Jan 1999 to Dec 2007) using information obtained from ward admission registers, theatre operation registers, and patients case files from the medical records department. The patients biodata, clinical, and operative findings as well as treatment outcome were extracted for analysis. Of 55 patients eligible for analysis, 44 (80%) were males and 11(20%) females (M to F, 4:1). Their ages ranged between 18 and 65 years with a mean(SD) of 39.9 (13.5) years. Most of the patients, 34 (61.8%), were below 40 years of age and majority 39(71.0%) had a history suggestive of chronic peptic ulcer disease. Twenty six (47.3%) patients presented within 24 hours of perforation, while nine (16.4%) presented more than 72 hours afterwards. The latter group accounted for most, five(55.6%), of the mortality. All the perforations were anterior pyloroduodenal and all except one had simple closure with omental patch followed by a course of a proton pump inhibitor and Helicobacter pylori eradication therapy. Simple closure with omental patch followed by Helicobacter pylori eradication is effective in managing PDU with low morbidity and mortality despite patients late presentation in our center. This technique is recommended in place of a definitive ulcer surgery.

Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) represent two of the most prevalent chronic respiratory disorders and cardiovascular diseases are major co-morbidities in both. Co-existence of both disorders (overlap syndrome) occurs in 1% of adults and overlap patients have worse nocturnal hypoxemia and hypercapnia than COPD and OSA patients alone. The present review discusses recent data concerning the pathophysiological and clinical significance of the overlap syndrome.

Stereotactic body radiation therapy (SBRT) achieves excellent local control for locally advanced pancreatic cancer (LAPC), but may increase late duodenal toxicity. Volumetric-modulated arc therapy (VMAT) delivers intensity-modulated radiation therapy (IMRT) with a rotating gantry rather than multiple fixed beams. This study dosimetrically evaluates the feasibility of implementing duodenal constraints for SBRT using VMAT vs IMRT. Non–duodenal sparing (NS) and duodenal-sparing (DS) VMAT and IMRT plans delivering 25 Gy in 1 fraction were generated for 15 patients with LAPC. DS plans were constrained to duodenal D{sub max} of<30 Gy at any point. VMAT used 1 360° coplanar arc with 4° spacing between control points, whereas IMRT used 9 coplanar beams with fixed gantry positions at 40° angles. Dosimetric parameters for target volumes and organs at risk were compared for DS planning vs NS planning and VMAT vs IMRT using paired-sample Wilcoxon signed rank tests. Both DS VMAT and DS IMRT achieved significantly reduced duodenal D{sub mean}, D{sub max}, D{sub 1cc}, D{sub 4%}, and V{sub 20} {sub Gy} compared with NS plans (all p≤0.002). DS constraints compromised target coverage for IMRT as demonstrated by reduced V{sub 95%} (p = 0.01) and D{sub mean} (p = 0.02), but not for VMAT. DS constraints resulted in increased dose to right kidney, spinal cord, stomach, and liver for VMAT. Direct comparison of DS VMAT and DS IMRT revealed that VMAT was superior in sparing the left kidney (p<0.001) and the spinal cord (p<0.001), whereas IMRT was superior in sparing the stomach (p = 0.05) and the liver (p = 0.003). DS VMAT required 21% fewer monitor units (p<0.001) and delivered treatment 2.4 minutes faster (p<0.001) than DS IMRT. Implementing DS constraints during SBRT planning for LAPC can significantly reduce duodenal point or volumetric dose parameters for both VMAT and IMRT. The primary consequence of implementing DS constraints for VMAT is increased dose to other organs at

We are reporting the first-to our knowledge-case of duodenal Plexiform Fibromyxoma causing obscure upper gastrointestinal bleeding. Plexiform fibromyxoma triggered recurrent upper gastrointestinal bleeding episodes in a 63-year-old man who remained undiagnosed, despite multiple hospitalizations, extensive diagnostic workups and surgical interventions (including gastrectomies), for almost 17 years. During hospitalization for the last bleeding episode, an upper gastrointestinal endoscopy revealed an intestinal hemorrhagic nodule. The lesion was deemed unresectable by endoscopic means. An abdominal computerized tomography disclosed no further lesions and surgery was decided. The lesion at operation was found near the edge of the duodenal stump and treated with pancreas-preserving duodenectomy (1st and 2nd portion). Postoperative recovery was mainly uneventful and a 20-month follow-up finds the patient in good health with no need for blood transfusions.Plexiform fibromyxomas stand for a rare and widely unknown mesenchymal entity. Despite the fact that they closely resemble other gastrointestinal tumors, they distinctly vary in clinical management as well as the histopathology. Clinical awareness and further research are compulsory to elucidate its clinical course and prognosis.

Obstruction of the inferior vena cava (IVC) is an uncommon condition, and the collateral pathway varies according to the level, extent, duration and the cause of obstruction. Membranous obstruction of IVC in its hepatic portion might be one of the principle cause among Korean, though not reported till now. Analytical study was performed in 26 cases of IVC obstruction with various cause. 1. The level of the obstruction showed relatively even distribution as follows, upper caval in 11 cases, middle caval in 6 cases and infrarenal in 9 cases. 2. The main cause of upper caval obstruction was membranous obstruction. 3. As a whole, the main collateral pathway was the central route (22 cases: 85%). 4. Characteristic collateral pathway unique to upper caval obstruction was transhepatic venous collateral, developed between the obstructed segment and unobstructed segment of IVC. 5. Scalloping of left cardiac border produced by pericardiophrenic venous collateral was characteristic simple chest x-ray finding in IVC obstruction

Glutamine modulates duodenal protein metabolism in fasted healthy humans, but its effects in a fed state remain unknown. We aimed to assess the effects of either glutamine or an isonitrogenous protein mixture on duodenal protein metabolism in humans in the fed state. Twenty-four healthy volunteers were randomly included in 2 groups. Each volunteer was studied on 2 occasions in a random order and received, during 5 h, either an enteral infusion of maltodextrins alone (0.25 g · kg⁻¹ · h⁻¹; both groups) that mimicked a carbohydrate fed state or maltodextrins with glutamine (group 1) or an isonitrogenous (22.4 mg N · kg⁻¹ · h⁻¹) protein powder (group 2). Simultaneously, a continuous intravenous infusion of ¹³C-leucine and ²H₅-phenylalanine (both 9 μmol · kg⁻¹ · h⁻¹) was performed. Endoscopic duodenal biopsies were taken. Leucine and phenylalanine enrichments were assessed by using gas chromatography-mass spectrometry in duodenal proteins and the intracellular free amino acids pool to calculate the mucosal fractional synthesis rate (FSR). Proteasome proteolytic activities and phosphokinase expression were assessed by using specific fluorogenic substrates and macroarrays, respectively. The FSR and proteasome activity were not different after the glutamine supply compared with after maltodextrins alone. In contrast, the FSR increased (1.7-fold increase; P protein-powder delivery without modification of total proteasome activity. The protein powder increased insulinemia, PI3 kinase, and erk phosphorylation but did not affect the mammalian target of rapamycin (mTOR) pathway and mitogen-activated protein kinase signal-integrating kinase 1 phosphorylation. A trend for an increase of eukaryotic translation initiation factor 4E phosphorylation was observed (P = 0.07). In the carbohydrate fed state, enteral proteins but not glutamine increased duodenal protein synthesis through an mTOR independent pathway in humans.

Rare Case of Duodenal Metastasis From Pulmonary Squamous Cell Carcinoma

Zain Memon DO

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.

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)

Conclusion: In very proximal high atresia, the extent of tapering is limited by the proximity of the ligament of Treitz. Duodenal derotation provides better access to the high atresia. The results of this limited experience suggest that the DDETJ procedure could provide an alternative therapy in patients with high jejunal atresia.

Gastrointestinal bypass surgeries that result in rerouting and subsequent exclusion of nutrients from the duodenum appear to rapidly alleviate hyperglycemia and hyperinsulinemia independent of weight loss. While the mechanism(s) responsible for normalization of glucose homeostasis remains to be fully elucidated, this rapid normalization coupled with the well-known effects of vagal inputs into glucose homeostasis suggests a neurohormonally mediated mechanism. Our results show that duodenal bypass surgery on obese, insulin-resistant Zucker fa/fa rats restored insulin sensitivity in both liver and peripheral tissues independent of body weight. Restoration of normoglycemia was attributable to an enhancement in key insulin-signaling molecules, including insulin receptor substrate-2, and substrate metabolism through a multifaceted mechanism involving activation of AMP-activated protein kinase and downregulation of key regulatory genes involved in both lipid and glucose metabolism. Importantly, while central nervous system-derived vagal nerves were not essential for restoration of insulin sensitivity, rapid normalization in hepatic gluconeogenic capacity and basal hepatic glucose production required intact vagal innervation. Lastly, duodenal bypass surgery selectively altered the tissue concentration of intestinally derived glucoregulatory hormone peptides in a segment-specific manner. The present data highlight and support the significance of vagal inputs and intestinal hormone peptides toward normalization of glucose and lipid homeostasis after duodenal bypass surgery.

It is known that at least 90% of duodenal ulcers are caused by infection with the bacterium Helicobacter pylori. Eradicating this organism usually results in complete resolution of the disease (Rosengren, Br J Gen Pract 46(409):491-492, 1996). To study the different changes if any in stomach wall at sites other than the ulcer in chronic duodenal ulcer patients by upper Gastro-Intenstinal Endoscopy followed by histopathological examination of different parts of stomach. This study was a retrospective study conducted in the Department of General surgery, V.S.S. Medical College, Burla, Sambalpur, odisha during the period of June 2007 to May 2009. Subjects were patients with chronic duodenal ulcer who underwent endoscopic examination, gastric biopsy and rapid urease test. Chronic gastritis of antrum, followed by erythematous pangastritis was the prominent feature both in endoscopy and histopathological examination. The Inflammatory change affected the mucosa and submucosa of the stomach wall. The prevalence rate of Helicobacter pylori was 84%, the antrum being the most common affected part (84%) followed by gastric fundus (41%). Chronic superficial atrophic gastritis of antrum, followed by pangastritis is the most common pathological abnormality in stomach wall in CDU cases. Gastric antrum is the most common site for H. pylori colonization followed by fundus. Presence of H. pylori in stomach wall is associated with active on chronic gastritis.

Ultrasonography is a predominantly accurate, relatively simple unique diagnostic method of obstructive jaundice. The ultrasonographic findings of obstructive jaundice are dilated intra- and extrahepatic duct with intraluminal hyper reflective echo or mass in and/ or around the bile duct. The superiority of high resolution real time ultrasonography for the diagnosis of obstructive jaundice is bases on the easy detectability of extra- and intrahepatic bile ducts by its multiple sectional images in a short time, the flexibility of probe and small crystal size. Author evaluated real time sonographic findings 46 obstructive jaundice patients confirmed by surgery or radiographical examinations. The results were: 1. Diameter of extrahepatic duct in obstructive jaundice were varied from normal to 4.0 Cm, mostly 8 to 10 mm in diameter (26%). Degree of dilatation of biliary duct appeared more prominent in cancer patients than other causes of obstruction. 2. The site of obstruction was detected in 85% (39/46) and its common site was common bile duct in 63% (29/46). 3. The diagnostic accuracy of choledocholithiasis and cancer was 82% (22/27) and 44% (4/9), respectively. Diagnostic accuracy of the real time ultrasonography in obstructive jaundice was over all 75% (34/46)

Duodenal epithelial cells need efficient defence strategies during gastric acidification of the lumen, while colonic mucosa counteracts damage by pathogens by building up a bacteria-free adherent mucus layer. Transport of HCO3(-) is considered crucial for duodenal defence against acid as well as for mucus release and expansion, but the transport pathways involved are incompletely understood. This study investigated the significance of the electroneutral Na(+)-HCO3(-) cotransporter NBCn1 for duodenal defence against acid and colonic mucus release. NBCn1 was localized to the basolateral membrane of duodenal villous enterocytes and of colonic crypt cells, with predominant expression in goblet cells. Duodenal villous enterocyte intracellular pH was studied before and during a luminal acid load by two-photon microscopy in exteriorized, vascularly perfused, indicator (SNARF-1 AM)-loaded duodenum of isoflurane-anaesthetized, systemic acid-base-controlled mice. Acid-induced HCO3(-) secretion was measured in vivo by single-pass perfusion and pH-stat titration. After a luminal acid load, NBCn1-deficient duodenocytes were unable to recover rapidly from intracellular acidification and could not respond adequately with protective HCO3(-) secretion. In the colon, build-up of the mucus layer was delayed, and a decreased thickness of the adherent mucus layer was observed, suggesting that basolateral HCO3(-) uptake is essential for optimal release of mucus. The electroneutral Na(+)-HCO3(-) cotransporter NBCn1 displays a differential cellular distribution in the murine intestine and is essential for HCO3(-)-dependent mucosal protective functions, such as recovery of intracellular pH and HCO3(-) secretion in the duodenum and secretion of mucus in the colon.

The objective of this study was to evaluate the function of the minor duodenal papilla and to investigate the relationship between the history of acute pancreatitis and individual dorsal pancreatogram findings and the minor papilla function in pancreas divisum. Eight of the 21 patients with PD diagnosed by endoscopic retrograde cholangiopancreatography had a history of acute pancreatitis (group A), and 13 patients did not (group B). The reaction of pancreatic juice excreted via the minor papilla was evaluated after intravenous administration of secretin, by observing the repulsion of indigo carmine dye scattered on the surface of the minor papilla. The function of the minor papilla was classified into two types. In 12 patients, all of the pigment on the minor papilla was repelled within 5 min of secretin administration (type I), and in the remaining nine patients it was not (type II). After secretin administration, the pH of the minor papilla surface in type I was significantly higher than that in type II. There was no significant difference between the type I and type II patients in exocrine pancreatic function, as evaluated by a BT-PABA test. In the group A patients, the rate of occurrence of dorsal duct dilation (including changes of the terminal shape) was significantly greater than in the group B patients. The function of the minor papilla in the group A patients was significantly worse than in the group B patients. Outflow obstruction of pancreatic group B patients. Outflow obstruction of pancreatic juice, i.e., "relative stenosis of the minor papilla," was considered to be present in the patients with type II papilla, and, therefore, the patients with type II papilla might suffer from acute pancreatitis resulting from poor drainage of pancreatic juice and excessive pressure in the dorsal duct. The finding that patients with PD have one of two types of minor papilla will be useful for understanding the condition and selecting the therapeutic plan for

 Many people with celiac disease are undiagnosed and there is evidence that insufficient duodenal samples may contribute to underdiagnosis. The aims of this study were to investigate whether more samples leads to a greater likelihood of a diagnosis of celiac disease and to elucidate factors that influence the number of samples collected.  We identified patients from two community hospitals who were undergoing duodenal biopsy for indications (as identified by International Classification of Diseases code) compatible with possible celiac disease. Three cohorts were evaluated: no celiac disease (NCD, normal villi), celiac disease (villous atrophy, Marsh score 3), and possible celiac disease (PCD, Marsh score celiac disease had a median of 4 specimens collected. The percentage of patients diagnosed with celiac disease with one sample was 0.3 % compared with 12.8 % of those with six samples ( P  = 0.001). Patient factors that positively correlated with the number of samples collected were endoscopic features, demographic details, and indication ( P  = 0.001). Endoscopist factors that positively correlated with the number of samples collected were absence of a trainee, pediatric gastroenterologist, and outpatient setting ( P  celiac disease significantly increased with six samples. Multiple factors influenced whether adequate biopsies were taken. Adherence to guidelines may increase the diagnosis rate of celiac disease.

Chronic intestinal pseudo-obstruction.

Science.gov (United States)

Gabbard, Scott L; Lacy, Brian E

2013-06-01

Chronic intestinal pseudo-obstruction (CIP) is a rare and serious disorder of the gastrointestinal (GI) tract characterized as a motility disorder with the primary defect of impaired peristalsis; symptoms are consistent with a bowel obstruction, although mechanical obstruction cannot be identified. CIP is classified as a neuropathy, myopathy, or mesenchymopathy; it is a neuropathic process in the majority of patients. The natural history of CIP is generally that of a progressive disorder, although occasional patients with secondary CIP note significant symptomatic improvement when the underlying disorder is identified and treated. Symptoms vary from patient to patient depending on the location of the luminal GI tract involved and the degree of involvement; however, the small intestine is nearly always involved. Common symptoms include dysphagia, gastroesophageal reflux, abdominal pain, nausea, vomiting, bloating, abdominal distension, constipation or diarrhea, and involuntary weight loss. Unfortunately, these symptoms are nonspecific, which can contribute to misdiagnosis or a delay in diagnosis and treatment. Since many of the symptoms and signs suggest a mechanical bowel obstruction, diagnostic tests typically focus on uncovering a mechanical obstruction, although routine tests do not identify an obstructive process. Nutrition supplementation is required for many patients with CIP due to symptoms of dysphagia, nausea, vomiting, and weight loss. This review discusses the epidemiology, etiology, pathogenesis, diagnosis, and treatment of patients with CIP, with an emphasis on nutrition assessment and treatment options for patients with nutrition compromise.

Fluctuating functions related to quality of life in advanced Parkinson disease: effects of duodenal levodopa infusion.

2008-12-01

To assess fluctuations in quality of life (QoL) and motor performance in patients with advanced Parkinson disease (PD) treated with continuous daytime duodenal levodopa/carbidopa infusion or conventional therapy. Of 18 patients completing a 6-week trial (DIREQT), 12 were followed for up to 6 months and assessed using electronic diaries and the PD Questionnaire-39 (PDQ-39). During the trial and follow-up, major diurnal fluctuations were observed, especially for hyperkinesia, 'off' time, ability to walk and depression. Duodenal infusion was associated with significantly more favourable outcomes compared with conventional treatment for satisfaction with overall functioning, 'off' time and ability to walk, with improved outcomes with PDQ-39. Relative to conventional treatment, infusion therapy may stabilize and significantly improve motor function and patient's QoL. The potential for daily fluctuation in PD symptoms means single measures of treatment effectiveness can result in bias in effect estimates and hence repeated measures are recommended.

Duodenal Ca2+ absorption is not stimulated by calcitriol during early postnatal development of pigs.

1998-08-01

The role of calcitriol in stimulating intestinal active Ca2+ absorption during postnatal life was studied in newborn, suckling, and weaned control (Con) piglets and piglets suffering from inherited calcitriol deficiency (Def piglets). In addition, a group of Def piglets was treated with vitamin D3 (Def-D3 piglets), which normalized plasma calcitriol levels. Regardless of age, duodenal calbindin-D9k concentrations ranged between 1,839 and 2,846 microg/g mucosa in Con piglets, between 821 and 1,219 microg/g mucosa in Def piglets, and between 2,960 and 3,692 microg/g mucosa in Def-D3 animals. In weaned animals, active Ca2+ absorption as calculated from in vitro 45Ca2+ flux rate measurements in Ussing chambers could be related to calbindin-D9k levels. Thus active Ca2+ absorption was completely absent in Def animals but was reconstituted in Def-D3 animals. In contrast, in newborn Def piglets active Ca2+ absorption functioned normally despite the low plasma calcitriol and mucosal calbindin-D9k levels and could not be affected by treatment with vitamin D3. Similar results were obtained from suckling Def piglets. The microtubule-disrupting agent colchicine caused significant inhibition of transepithelial net Ca2+ absorption in duodenal epithelia from newborn piglets without exerting an effect in suckling and weaned animals. Colchicine had no effect on Ca2+ uptake across the brush border membrane of mucosal enterocytes or on glucose-dependent electrogenic net ion flux rates in duodenal preparations from newborn Con piglets. In conclusion, our findings reveal intestinal active Ca2+ absorption during early postnatal life of pigs that involves calcitriol-independent mechanisms and that may include intact microtubule actions.

Besides TCRαβ+ CD4+ cells, no other phenotypes have been shown to be gluten-reactive. Using flow cytometry on lymphocytes from duodenal biopsies, we determined that the number of B cells (CD3- CD19+ and the number of CD3+ CD4- CD8- double-negative (DN T cells were elevated 6-7 fold in children with CD. We next isolated and quantified intraepithelial lymphocytes (IELs from biopsies obtained from patients (both children and adults with CD, potential CD and non-CD controls. Flow cytometric analysis of the duodenal T cell subpopulations was performed including the markers TCRαβ, TCRγδ, CD4, CD8α and CD8β. Proportions of γδ T cells and CD8αβ+ cells among IELs were increased in CD patients, whereas proportions of CD4+ CD8αα+ and CD4+ single-positive T cells were decreased. Additionally, two gluten-reactive T cell lines (TCLs derived from CD biopsies were analyzed for changes in proportions of T cell subsets before and after gluten stimulation. In a proliferation assay, dividing cells were tracked with carboxyfluorescein succinimidyl ester (CFSE, and both αβ and γδ T cells proliferated in response to gluten. Changes in duodenal T cell subpopulations in potential CD patients followed the same pattern as for CD patients, but with less pronounced effect.

AimTo investigate and compare the efficacy and safety of percutaneous transhepatic biliary stenting (PTBS) using a one- or two-stage procedure and determine the predictive factors for the efficacious treatment of malignant hilar obstruction (MHO).Methods159 consecutive patients with MHO who underwent PTBS were enrolled between January 2010 and June 2013. Patients were classified into one- or two-stage groups. Independent predictors of therapeutic success were evaluated using a logistic regression model.Results108 patients were treated with one-stage PTBS and 51 patients were treated with two-stage PTBS. The stents were technically successful in all patients. Successful drainage was achieved in 114 patients (71.4 %). A total of 42 early major complications were observed. Re-interventions were attempted in 23 patients during follow-up. The cumulative primary patency rates at 3, 6, and 12 months were 88, 71, and 48 %, respectively. Stent placement using a one- or two-stage procedure did not significantly affect therapeutic success, early major complications, median stent patency, or survival. A stent placed across the duodenal papilla was an independent predictor of therapeutic success (odds ratio = 0.262, 95 % confidence interval [0.107–0.642]). Patients with stents across papilla had a lower rate of cholangitis compared with patients who had a stent above papilla (7.1 vs. 20.3 %, respectively, p = 0.03).ConclusionsThe majority of patients with MHO who underwent one-stage PTBS showed similar efficacy and safety outcomes compared with those who underwent two-stage PTBS. Stent placement across the duodenal papilla was associated with a higher therapeutic success rate.

Peritonitis secondary to traumatic duodenal laceration in the presence of a large pancreatic pseudocyst: a case report

Directory of Open Access Journals (Sweden)

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

To evaluate the efficacy and safety of emergency endoscopic needle-knife precut papillotomy in acute severe cholangitis resulting from impacted common bile duct stones at duodenal papilla. Between January 2010 and January 2015, 118 cases of acute severe cholangitis with impacted common bile duct stones at the native papilla underwent emergency endoscopic retrograde cholangiopancreatography (ERCP) and early needle-knife precut papillotomy in a tertiary referral center. Precut techniques were performed according to the different locations of stones in the duodenal papilla. Clinical data about therapy and recovery of the 118 patients were recorded and analyzed. One hundred and eighteen patients underwent emergency ERCP within 24 h after hospitalization, with a total success rate of 100%. The mean operating time was 6.4 ± 4.1 min. Postoperative acute physiology and chronic health evaluation (APACHE) II scores, white blood cell count and liver function improved significantly. The complication rate was 4.2% (5/118); two with hemorrhage and three with acute pancreatitis. There was no procedure-related mortality. Emergency endoscopic needle-knife precut papillotomy is effective and safe for acute severe cholangitis resulting from impacted common bile duct stones at the duodenal papilla.

Moche, Jason A; Palmer, Orville

2012-05-01

The proper evaluation of the patient with nasal obstruction relies on a comprehensive history and physical examination. Once the site of obstruction is accurately identified, the patient may benefit from a trial of medical management. At times however, the definitive treatment of nasal obstruction relies on surgical management. Recognizing the nasal septum, nasal valve, and turbinates as possible sites of obstruction and addressing them accordingly can dramatically improve a patient's nasal breathing. Conservative resection of septal cartilage, submucous reduction of the inferior turbinate, and structural grafting of the nasal valve when appropriate will provide the optimal improvement in nasal airflow and allow for the most stable results.

2016-08-01

The purpose of this article is to provide an update on methods for palliating symptoms in patients with histologically benign and malignant central airway obstruction. We review the published literature within the past decade on postintubation, posttracheostomy, and TB- and transplant-related airway strictures; tracheobronchomalacia; and malignant airway obstruction. We review terminology, classification systems, and parameters that impact treatment decisions. The focus is on how airway stent insertion fits into the best algorithm of care. Several case series and cohort studies demonstrate that airway stents improve dyspnea, lung function, and quality of life in patients with airway obstruction. Airway stenting, however, is associated with high rates of adverse events and should be used only when curative open surgical interventions are not feasible or are contraindicated.

Inferior vena cava obstruction and shock

Directory of Open Access Journals (Sweden)

Megri Mohammed

2018-01-01

Full Text Available Shock is one of the most challenging life-threatening conditions with high mortality and morbidity; the outcomes are highly dependent on the early detection and management of the condition. Septic shock is the most common type of shock in the Intensive Care Unit. While not as common as other subsets of shock, obstructive shock is a significant subtype due to well defined mechanical and pathological causes, including tension pneumothorax, massive pulmonary embolism, and cardiac tamponade. We are presenting a patient with obstructive shock due to inferior vena cava obstruction secondary to extensive deep venous thrombosis. Chance of survival from obstructive shock in our patient was small; however, there was complete and immediate recovery after treatment of the obstruction on recognizing the affected vessels. This case alerts the practicing intensivist and the emergency medicine physician to consider occlusion of the great vessels other than the pulmonary artery or aorta as causes of obstructive shock.

Chronic obstructive pulmonary disease and obstructive sleep apnea. Association, consequences and treatment.

Science.gov (United States)

Pronzato, C

2010-12-01

Obstructive sleep apnea syndrome (OSAS) and chronic obstructive pulmonary disease (COPD) are two diseases that often co-exist within an individual. This co-existence, known as overlap syndrome (OS), is the result of chance rather than a pathophysiological linkage and epidemiological studies indicate a prevalence of 1% in adult males. Patients vith OS have a more important sleep-related O2 desaturation than COPD patients with the same degree of bronchial obstruction and show an increased risk of developing hypercapnic respiratory failure and pulmonary hypertension when compared with patients affected by only one of he diseases. COPD and OSAS are independent risk factors for cardiovascular events and their co-existence in OS probably increases this risk. Evidence of systemic inflammation in COPD and sleep apnea and consequentely OS, is interesting because it may contribute to the pathogenesis of cardiovascular diseases. Treatment consists of continuous positive airway pressure (CPAP) or non-invasive positive pressure ventilation (NIPPV), with or without associated O2, for correction of the upper airway obstructive episodes and hypoxemia during sleep.

2018-01-01

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.

AIM: To analyze our experience in patients with duodenal gastrointestinal stromal tumors (GIST) and review the appropriate surgical approach. METHODS: We retrospectively reviewed the medical records of all patients with duodenal GIST surgically treated at our medical institution between 2002 and 2011. Patient files, operative reports, radiological charts and pathology were analyzed. For surgical therapy open and laparoscopic wedge resections and segmental resections were performed for limited resection (LR). For extended resection pancreatoduodenectomy was performed. Age, gender, clinical symptoms of the tumor, anatomical localization, tumor size, mitotic count, type of resection resectional status, neoadjuvant therapy, adjuvant therapy, risk classification and follow-up details were investigated in this retrospective study. RESULTS: Nine patients (5 males/4 females) with a median age of 58 years were surgically treated. The median follow-up period was 45 mo (range 6-111 mo). The initial symptom in 6 of 9 patients was gastrointestinal bleeding (67%). Tumors were found in all four parts of the duodenum, but were predominantly located in the first and second part of the duodenum with each 3 of 9 patients (33%). Two patients received neoadjuvant medical treatment with 400 mg imatinib per day for 12 wk before resection. In one patient, the GIST resection was done by pancreatoduodenectomy. The 8 LRs included a segmental resection of pars 4 of the duodenum, 5 wedge resections with primary closure and a wedge resection with luminal closure by Roux-Y duodeno-jejunostomy. One of these LRs was done minimally invasive; seven were done in open fashion. The median diameter of the tumors was 54 mm (14-110 mm). Using the Fletcher classification scheme, 3/9 (33%) tumors had high risk, 1/9 (11%) had intermediate risk, 4/9 (44%) had low risk, and 1/9 (11%) had very low risk for aggressive behaviour. Seven resections showed microscopically negative transsection margins (R0), two

In patients with duodenal ulcer, mucosal blood flow of pentagastrin-stimulated stomach was studied using sup(99m)Tc-methylaminophenazone clearance technique published previously by the authors. Comparative investigations were carried out in active and inactive phases of the disease and in operated patients before and after highly selective vagotomy. The relation between gastric mucosal blood flow and acid secretion proved to be different from that of the normacid controls: in duodenal ulcer patients the secretory capacity in relation to the blood supply proved to be increased. Both the mucosal blood flow and acid secretion values were elevated in the active stage as compared to the inactive phase, while the proportion between them remained unchanged. The relation of secretion to mucosal blood flow after highly selective vagotomy became similar to that of the normal controls. It is suggested that the sup(99m)Tc-methylaminophenazone clearance method is a suitable tool to evaluate the effectiveness of vagotomy. (author)

To assess the accuracy of intestinal ultrasound for diagnosis of intestinal obstruction in dogs and cats. A prospective clinical study was performed. Inclusion criteria were dogs and cats with clinical signs suggestive of gastrointestinal obstruction. Animals with no obstruction detected on ultrasound were excluded if they could not be monitored for 48 hours to confirm absence of obstruction. Sonographic diagnosis of small intestinal obstruction was based on identification of at least two findings suggestive of intestinal obstruction. Ninety-two patients suspected of having intestinal obstruction were included. Correct diagnosis of intestinal obstruction was made in 21 cases (23%), and in 68 (74%) this diagnosis was excluded. Interpretation of the images on prospective analysis had sensitivity, positive predictive, specificity and negative predictive values of 100%, 87.5%, 95.8% and 100%, respectively. Ultrasonography is an excellent method for investigation of animals with gastrointestinal disorders, and is particularly useful for excluding obstructive processes. © 2011 British Small Animal Veterinary Association.

Magnetic resonance in obstructive jaundice

1989-01-01

Twelve cases of obstructive jaundice in whom ultrasound failed to demonstrate the site and/or the cause of obstruction of the biliary tract were examined with magnetic resonance imaging (MRI), correctly diagnosing the site and cause of obstruction in 10 of 12 surgically proven cases. In one case of cholangiocarcinoma, the site of obstruction was well shown on MR but a definite cause could not be ascertained. In another patient who developed intermittent jaundice following surgery for choledochal cyst, MR demonstrated a solitary stone in the common hepatic duct. Surgical confirmation could not be achieved as the patient was lost to follow up. There were 6 cases of choledocholithiasis, 3 cases of gall bladder carcinoma and one case each of pancreatic adenocarcinoma and cholangiocarcinoma. It is believed that MRI will provide obstructive jaundice and will be able to minimize the use of percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiopancreatography (ERCP) in view of its ability to perform multiplanar imaging in multiple sequences. 11 refs., figs., 1 tab

Objective: To evaluate the angiographic feature of hepatic vein obstruction. Methods Forty-five patients (male 23, female 22, age 9-54 years) suffered from hepatic vein obstruction. The inferior vena cavography and the hepatic venography were performed in all cases. Results: IVC was free in 37 patients with hepatic vein obstruction, both IVC and HV were obstructed in 8 patients. The local or long stenosis of IVC was found in 31 inferior vena cavography. The diameter of IVC was normal in 12 patients. The sign of membranous dome was found in hepatic vein orifice in 5 cases and in accessory hepatic vein orifice in 4 cases. Intrahepatic venous collaterals were found in 45 cases. Conclusion: Hepatic vein obstruction can be reproached primarily in inferior vena cavography, the membranous dome is a direct sign of membranous obstruction of HV and AHV in inferior vena cavography. The selected hepatic venography can provide reliable evidence to diagnose hepatic vein obstruction

Acid suppression increases rates of Barrett's esophagus and esophageal injury in the presence of duodenal reflux.

LENUS (Irish Health Repository)

2012-01-31

BACKGROUND: The contribution of gastric acid to the toxicity of alkaline duodenal refluxate on the esophageal mucosa is unclear. This study compared the effect of duodenal refluxate when acid was present, decreased by proton pump inhibitors (PPI), or absent. METHODS: We randomized 136 Sprague-Dawley rats into 4 groups: group 1 (n = 33) were controls; group 2 (n = 34) underwent esophagoduodenostomy promoting "combined reflux"; group 3 (n = 34) underwent esophagoduodenostomy and PPI treatment to decrease acid reflux; and group 4, the \\'gastrectomy\\' group (n = 35) underwent esophagoduodenostomy and total gastrectomy to eliminate acid in the refluxate. Esophaguses were examined for inflammatory, Barrett\\'s, and other histologic changes, and expression of proliferative markers Ki-67, proliferating cell nuclear antigen (PCNA), and epidermal growth factor receptor (EGFR). RESULTS: In all reflux groups, the incidence of Barrett\\'s mucosa was greater when acid was suppressed (group C, 62%; group D, 71%) than when not suppressed (group B, 27%; P = 0.004 and P < .001). Erosions were more frequent in the PPI and gastrectomy groups than in the combined reflux group. Edema (wet weight) and ulceration was more frequent in the gastrectomy than in the combined reflux group. Acute inflammatory changes were infrequent in the PPI group (8%) compared with the combined reflux (94%) or gastrectomy (100%) groups, but chronic inflammation persisted in 100% of the PPI group. EGFR levels were greater in the PPI compared with the combined reflux group (P = .04). Ki-67, PCNA, and combined marker scores were greater in the gastrectomy compared with the combined reflux group (P = .006, P = .14, and P < .001). CONCLUSION: Gastric acid suppression in the presence of duodenal refluxate caused increased rates of inflammatory changes, intestinal metaplasia, and molecular proliferative activity. PPIs suppressed acute inflammatory changes only, whereas chronic inflammatory changes persisted.

The effect of acute or chronic administration of duodenal ulcerogens on gastric emptying (GE) of a liquid meal was investigated. In Sprague-Dawley rats (150-200g) 2 ml of /sup 51/Cr in 2% dextrose (5000 CPM) was given intragastrically and the GE half life was established as 7.6 min (controls). In acute experiments, C (30mg/100g), M (40mg/100g) or MPTP (4mg/100g) injected subcutaneously all delayed GE at 1, 2, 4, 8 and 24 hr by 15-77%. Maximal GE delay (p<0.05) by 77, 48 or 71% was found 1, 1 or 2 hr after C, M or MPTP, respectively. In chronic experiments, C (22mg/100g) was given x3 on the first day and once daily (25mg/100g) for 3 or 10 additional days. M (20mg/100g) once daily and MPTP (4mg/100g) x3 daily were given for 4 or 11 days. GE was measured on the 5th and 12th day. Chronically, MPTP accelerated GE by 63 and 31% at 5 and 12 days (p<0.05) and C and M did not change GE. The severity of duodenal ulcers correlated (p<0.05) with the amount of /sup 51/Cr remaining in the stomach: r=-0.68, -0.74 and -0.70 after C, M and MPTP, respectively. Acute administration of duodenal ulcerogens delay GE in rats. Chronic treatment with duodenal ulcerogens either accelerates or does not change GE. The most severe chronic ulcers exhibit the most rapid emptying. The authors data suggest that rapid GE might be a secondary rather than a primary alteration in duodenal ulceration.

Impairment of bone mineral density (BMD) is frequent in celiac disease (CD) patients on a gluten-free diet (GFD). The normalization of intestinal mucosa is still difficult to predict. We aim to investigate the relationship between BMD and duodenal mucosa healing (DMH) in CD patients on a GFD. Sixty-four consecutive CD patients on a GFD were recruited. After a median period of a 6-year GFD (range 2-33 years), patients underwent repeat duodenal biopsy and dual-energy X-ray absorptiometry (DXA) scan. Twenty-four patients (38%) displayed normal and 40 (62%) low BMD, 47 (73%) DMH, and 17 (27%) duodenal mucosa lesions. All patients but one with normal BMD (23 of 24, 96%) showed DMH, while, among those with low BMD, 24 (60%) did and 16 (40%) did not. At multivariate analysis, being older (odds ratio (OR) 1.1, 95% confidence interval (CI) 1.03-1.18) and having diagnosis at an older age (OR 1.09, 95% CI 1.03-1.16) were associated with low BMD; in turn, having normal BMD was the only variable independently associated with DMH (OR 17.5, 95% CI 1.6-192). In older CD patients and with late onset disease, BMD recovery is not guaranteed, despite a GFD. A normal DXA scan identified CD patients with DMH; thus, it is a potential tool in planning endoscopic resampling.

We herein report our experience regarding unusual causes of bowel obstruction to increase the awareness of surgeons regarding this disease. From 1991 to 2003, we had experience at the University affiliated hospitals, northern Jordan with 24 patients with small bowel obstruction resulting from unusual causes. We retrospectively reviewed the medical records of these patients with regards to the mode of presentation, cause of obstruction, radiological and operative findings, management and outcome. We recorded 15 patients who underwent previous abdominal surgery. Preoperative diagnosis was correct in only one patient with an internal hernia, but the abdominal CT scan suggested the diagnosis in 5 of the 9 patients who had the scan. The final diagnosis was internal hernias in 11 patients, foreign bodies in 5, ischemic strictures in 3, carcinoid tumors in 2, endometriosis in 2, and metastatic deposit from interstitial bladder carcinoma in one patient. Nine of the 12 patients with recurrent obstruction had either short course or recurrence obstruction during the same hospital admission. W carried out bowel resections in 15 patients (5 resections were due to bowel strangulation). Post operative death occurred in 4 patients. Awareness of these rare causes of intestinal obstruction even in patients with previous abdominal operation might improve the outcome. The tentative diagnosis of adhesion obstruction in patients with unusual obstructive etiology might lead to a higher rate of gangrenous complications. Rigorous preoperative evaluation including careful history and early abdominal CT may show the obstructive cause. (author)

Background: Intestinal obstruction occurs when the normal flow of intestinal contents is interrupted. The most frequent causes of intestinal obstruction are postoperative adhesions and hernias, which cause extrinsic compression of the intestine. Less frequently, tumours or strictures of the bowel can cause intrinsic blockage. Objective of the study was to find out the various a etiological factors of mechanical intestinal obstruction and to evaluate the morbidity and mortality in adult patients presenting to Surgical 'A' unit of Ayub teaching hospital with mechanical intestinal obstruction. Methods: This cross-sectional study was conducted from March 2009 to September, 2009. All patients presenting with intestinal obstruction and were above the age of 12 years were included in the study. Patients with non-mechanical obstruction were excluded from the study and those who responded to conservative measures were also excluded. Results: A total of 36 patients with age ranging from 12 to 80 years (Mean age 37.72+-19.74 years) and male to female ratio of 1.77:1, were treated for mechanical intestinal obstruction. The most common cause for mechanical intestinal obstruction was adhesions (36.1%). Intestinal tuberculosis was the second most common cause (19.4%), while hernias and sigmoid volvulus affected 13.9% patients each. Malignancies were found in 5.6% cases. Conclusion: Adhesions and Tuberculosis are the leading causes of mechanical intestinal obstruction in Pakistan. Although some patients can be treated conservatively, a substantial portion requires immediate surgical intervention. (author)

To evaluate the effectiveness and the safety of the spa and resort-based health-promoting treatment of the vehicle drivers (VD) presenting with duodenal ulcer disease. A total of 67 men suffering from duodenal ulcer disease (DUD) were allocated to two groups. The patients of group 1 (n = 35) were given the courses of balneotherapy that included bromine-iodine mineral baths with a temperature of 36-37 degrees C (8-9 procedures 10-15 min long each every second day) in combination with 8-9 peloid applications to the epigastric region (temperature 38-40 degrees C for 10-15 min every second day). The patients of group 2 (n = 32) were given the similar courses of therapy that included nitric thermal mineral baths with a temperature of 36-37 degrees C (8-9 procedures 10-15 min long each every second day) in combination with 8-9 peloid applications to the epigastric region (38-40 degrees C for 10-15 min every second day). The effectiveness and safety of these balenotherapeutic procedures for the treatment of duodenal ulcer disease in the subjects of the study and control (n = 47) groups were evaluated based on the results of the routine clinical and endoscopic examination, psychological and psychophysiological tests, and the comparative analysis of medical aid appeal-ability and disability cases during twelve months. Dynamics of clinical and instrumental characteristics (subjective, objective, clinical, endoscopic, psychophysiological) suggested the improvement of the health status in 88.6% and 84.4% of the drivers with duodenum ulcer in the two study groups respectively. Some of the patients comprising group 1 showed significant negative dynamics of the operative reaction system while the patients of group 2 demonstrated the marked improvement of the professionally significant functions and properties (PSF&P). The comparative analysis of medical aid appealability, disability cases, frequency of relapses and complications revealed the favorable clinical course of duodenal

2016-09-01

Full Text Available Sleep-related breathing disorders in children are a clinical problem which is more and more often diagnosed by doctors nowadays. They can be the basis for diagnosing obstructive sleep apnoea syndrome that causes a number of complications: lowering the quality of life, behavioural problems, complications involving cardiovascular system. The incidence of obstructive sleep apnoea syndrome in the paediatric population is estimated to be at the level of 2%. The symptoms of obstructive sleep apnoea syndrome can be divided into daytime and night ones. Night symptoms in children include: snoring, apnoea, breathing with open mouth (both during the day and at night, dry tongue and mouth during sleep, agitated sleep in unnatural positions. Among daytime symptoms of obstructive sleep apnoea syndrome there are: irritability, aggressiveness, hyperactivity, attention deficit disorder, delayed development and growth pattern (mainly failure to thrive, learning problems, morning headaches. Parents often do not connect the night and daytime symptoms with the possible development of obstructive sleep apnoea syndrome in their children. The main predisposing factor of obstructive sleep apnoea syndrome in children is adenotonsillar hypertrophy. Effective and in most cases preferred treatment for the management of obstructive sleep apnoea syndrome in children is adenotonsillectomy. Polysomnography and polygraphy are diagnostic tools helpful in the study of sleep-related disorders. The objective of this study was to systematise the knowledge on the epidemiology, aetiology, clinical image and prevention of obstructive sleep apnoea syndrome in children.

2008-01-01

The obstructive acute abdomen is a common presentation, for which safe and effective management depends on a fast and accurate diagnosis. Conventional radiograph remains the first choice among the imaging exams because of its availability, low cost and the possibility to be done serially to follow the patient's clinical progression. The ultrasonography does not require ionizing radiation. It is a dynamic and in realtime exam. Computed tomography is used increasingly due to the provision of essential diagnostic information not apparent from radiographs, such as the confirmation of the obstruction, degree and place of the occlusion, presence of ischemia as well as the causes of the obstruction. Magnetic resonance imaging has presented great technological advances and it may play a role in the future of obstructive acute abdomen diagnosis. The objective of this pictorial essay is to review the different imaging techniques used on diagnosing obstructive acute abdomen. (author)

Palliative Percutaneous Jejunal Stent for Patients with Short Bowel Syndrome

2009-04-01

Full Text Available Gastrointestinal obstruction is a common preterminal event in patients with gastric and pancreatic cancer who often undergo palliative bypass surgery. Although endoscopic palliation with self-expandable metallic stents has emerged as a safe and effective alternative to surgery, experience with this technique remains limited. In particular, a proximal jejunal obstruction requires more technical expertise than a duodenal obstruction. Palliative treatment modalities include both surgical and nonsurgical approaches. In this report, we describe the successful placement of self-expandable metallic stents at the proximal jejunum using a combination of percutaneous endoscopic, intraoperative, and transstomal stenting. Usually endoscopy is not indicated in cases of proximal jejunal obstruction, but some cases may require palliative endoscopy instead of bypass operation.

Our objective was to determine duodenal and ileal flows of total and esterified fatty acids and to determine ruminal fermentation characteristics and site and extent of nutrient digestion in sheep fed an 80% concentrate diet supplemented with high-linoleate (77%) safflower oil at 0, 3, 6, and 9% of DM. Oil was infused intraruminally along with an isonitrogenous basal diet (fed at 2% of BW) that contained bromegrass hay, cracked corn, corn gluten meal, urea, and limestone. Four crossbred wethers (BW = 44.3 +/- 15.7 kg) fitted with ruminal, duodenal, and ileal cannulas were used in a 4 x 4 Latin square experiment, in which 14 d of dietary adaptation were followed by 4 d of duodenal, ileal, and ruminal sampling. Fatty acid intake increased (linear, P = 0.004 to 0.001) with increased dietary safflower oil. Digestibilities of OM, NDF, and N were not affected (P = 0.09 to 0.65) by increased dietary safflower oil. For total fatty acids (free plus esterified) and esterified fatty acids, duodenal flow of most fatty acids, including 18:2c-9,c-12, increased (P = 0.006 to 0.05) with increased dietary oil. Within each treatment, duodenal flow of total and esterified 18:2c-9,c-12 was similar (P = 0.32), indicating that duodenal flow of this fatty acid occurred because most of it remained esterified. Duodenal flow of esterified 18:1t-11 increased (P = 0.08) with increased dietary safflower oil, indicating that reesterification of ruminal fatty acids occurred. Apparent small intestinal disappearance of most fatty acids was not affected (P = 0.19 to 0.98) by increased dietary safflower oil, but increased (P = 0.05) for 18:2c-9,c-12, which ranged from 87.0 to 97.4%, and for 18:2c-9,t-11 (P = 0.03), which ranged from 37.9% with no added oil to 99.2% with supplemental oil. For esterified fatty acids, apparent small intestinal disappearance was from 80% for 18:3c-9,c-12,c-15 at the greatest level of dietary oil up to 100% for 18:1t-11 and 18:1c-12 with 0% oil. We concluded that

Purpose: To assess dacryocystoplasty in the treatment of epiphora due to obstructions of the common canaliculus.Methods: Twenty patients with severe epiphora due to partial (n = 16) or complete (n = 4) obstruction of the common canaliculus underwent fluoroscopically guided dacryocystoplasty. In all cases of incomplete obstruction balloon dilation was performed. Stent implantation was attempted in cases with complete obstruction. Dacryocystography and clinical follow-up was performed at intervals of 1 week, and 3, 6, 12, and 18 months after the procedure. The mean follow-up was 6 months (range 3-18 months).Results: Balloon dilation was technically successfully performed in all patients with incomplete obstructions (n = 16). In three of four patients with complete obstruction stent implantation was performed successfully. Subsequent to failure of stent implantation in one of these patients balloon dilation was performed instead. The long-term primary patency rate in patients with incomplete obstructions was 88% (n = 14/16). In three of four cases with complete obstruction long-term patency was achieved during follow-up. Severe complications, infections, or punctal splitting were not observed.Conclusion: Fluoroscopically guided balloon dacryocystoplasty is a feasible nonsurgical therapy in canalicular obstructions with good clinical results that may be used as an alternative to surgical procedures. In patients with complete obstructions stent placement is possible but further investigations are needed to assess the procedural and long-term results.

The utilization of esophagogastroduodenoscopy (EGD) and related procedures continues to rise. Due to this increase in utilization is an inevitable rise in serious complications such as hemorrhage and perforation. One understudied and dreaded complication of EGD causing significant morbidity and mortality is duodenal perforation. We present the case of a 63-year-old male who presented to our institution's emergency room with dyspepsia, melanic stools, tachycardia, and hypotension. Initial laboratory evaluation was significant for severe anemia, lactic acidosis, and acute kidney injury, while CT scan of the abdomen pelvis did not suggest retroperitoneal hematoma or bowel perforation. An emergent EGD was performed which showed multiple bleeding duodenal ulcers that were cauterized and injected with epinephrine. Post-procedure the patient developed worsening abdominal pain, distension, diaphoresis, and tachypnea, requiring emergent intubation. A CT scan of the abdomen and pelvis with oral contrast confirmed pneumoperitoneum and duodenal perforation. Due to the patient's hemodynamic instability and multiple comorbidities, he was treated non-operatively with strict bowel rest and intravenous antibiotics. The patient ultimately had a 19-day hospital course complicated by renal failure requiring hemodialysis and an ischemic limb necessitating above knee amputation. This case describes an unsuccessful attempt at nonoperative management of duodenal perforation following EGD. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Full Text Available Background: Intestinal obstruction is a life threatening condition in the newborn, with attendant high mortality rate especially in underserved subregion. This study reports the aetiology, presentation, and outcome of intestinal obstruction management in neonates. Materials and Methods: A prospective study of neonatal intestinal obstruction at the University of Benin Teaching Hospital, Benin, Nigeria, between January 2006-June 2008. Data were collated on a structured proforma and analysed for age, sex, weight, presentation, type/date of gestation/delivery, aetiology, clinical presentation, associated anomaly, treatment, and outcome. Results: There were 71 neonates, 52 were males and 19 were females (2.7:1. Their age range was between 12 hours and 28 days (mean, 7.9 ± 2.7 days and they weighed between 1.8 and 5.2 kg (average, 3.2 kg. The causes of intestinal obstruction were: Anorectal anomaly, 28 (39.4%; Hirschsprung′s disease, 8 (11.3%′ prematurity, 3 (4.2%; meconeum plug, 2 (2.8%; malrotation, 6 (8.5%; intestinal atresia, 8 (11.3%; necrotising enterocolitis (NEC, 4 (5.6%; obstructed hernia, 4 (5.6%; and spontaneous gut perforation, 3 (4.2%. Also, 27 (38% children had colostomy, 24 (33.8% had laparotomy, 9 (12.8% had anoplasty, while 11 (15.4% were managed nonoperatively. A total of 41 (57.7% neonates required incubator, 26 (36.6% needed total parenteral nutrition, while 15 (21.1% require d paediatric ventilator. Financial constraint, late presentation, presence of multiple anomalies, aspiration, sepsis, gut perforation, and bowel gangrene were the main contributors to death. Neonates with lower obstructions had a better outcome compared to those having upper intestinal obstruction ( P < 0.0001. Conclusion: Outcomes of intestinal obstruction are still poor in our setting; late presentation, financial constraints, poor parental motivation and lack of basic facilities were the major determinants of mortality.

Is ursodeoxycholic acid detrimental in obstructive cholestasis? A propos of a case of malignant biliary obstruction.

Science.gov (United States)

Bessone, Fernando; Roma, Marcelo Gabriel

2016-01-01

Ursodeoxycholic acid (UDCA) is the first choice medication for most cholestatic hepatopathies, due to its capability to counteract inflammation and bile-acid-induced liver damage, two common features in cholestasis. However, UDCA is usually contraindicated in obstructive cholestasis, due to the alleged risk of biliary integrity disruption due to its choleretic effect. We report on an 83-year-old man with an unsuspected malignant biliary obstruction who received moderate doses of UDCA (8-12 mg/kg/day) for 5 weeks, because the preliminary evidence suggested he had chemotherapy-induced cholestasis. Liver integrity was extensively protected by UDCA, as indicated by a marked decrease in serum liver enzymes, despite a steady increase in the levels of bilirubin and serum bile acids due to the obstructive process. In conclusion, this report shows, for the first time in humans, that moderate UDCA doses can reduce liver injury associated with complete biliary obstruction. This may contribute to a better understanding of the risk-benefit ratio of the use of UDCA in obstructive cholangiopathies.

Krokidis, Miltiadis E.; Hatzidakis, Adam A.; Manousaki, Eirini G.; Gourtsoyiannis, Nicholas C.

2008-01-01

We report a case of simultaneous late migration of two ePTFE-FEP covered biliary endoprostheses (Viabil, W.L. Gore, Flagstaff, AZ, USA) that were percutaneously implanted for the treatment of malignant obstructive jaundice. The first Viabil covered stent was placed successfully without any evidence of dislocation or other complication during follow-up. Occlusion of the stent occurred 4 months later and was treated with the placement of a second stent of the same type. Thirteen months later the patient became symptomatic. Percutaneous transhepatic cholangiography (PTC) revealed the presence of a choledocho-duodenal fistula and the disappearance of the two endoprostheses previously implanted. A third metallic stent was then percutaneously positioned through the bilioenteric fistula. The computed tomography scan that followed for the detection of the metallic bodies did not reveal the dislocated metallic stents. Stent migration is a well-known complication of uncovered metallic stents, though Viabil stent migration is assumed to be most unlikely to happen due to the stent's anchoring barbs. Furthermore, the stent had already been tightly fixed by tumor over- and ingrowth, as recognized in previous imaging. This is a very unusual case, describing the disappearance of two metallic foreign bodies encapsulated by tumor

1994-01-01

Three-dimensional(3D) magnetic resonance(MR) projection imaging was evaluated as a noninvasive alternative to direct cholangiography for the assessment of its reliability in patients with obstructive jaundice. A heavily T2-weighted gradient-echo sequence(PSIF) was used for 3D MR projection imaging of the biliary system in five healthy volunteers and 25 patients with obstructive jaundice. The 3D images of the bile ducts were formed by stacking consecutive coronal MR images obtained with a fast imaging method to a maximum-intensity projection algorithm. In the volunteers, MR cholangiography could demonstrate the anatomy of the biliary tract in only two subjects. The extrahepatic and intrahepatic bile ducts were well visualized in 23 patients with obstructive jaundice. The leve of obstruction and the grade of dilatation were depicted with MR cholangiography in all cases. And the cause of obstruction could be determined with MR cholangiography in 18 cases, MR cholangiography wa successful in two patients in whom ERCP failed. The gallbladder or dilated pancreatic duct not demonstrated by means of direct cholangiography was demonstrated with MR cholangiography in six cases. MR cholangiography may be a useful adjunctive tool for the noninvasive evaluation of patients with obstructive Jaundice

It is well known that the computed tomography (CT) is very useful in the evaluation of obstructive jaundice. We have studied 55 cases of obstructive jaundice with whole body scanner from Jun.1980 to Jun. 1981. The results were as follows: 1. The sex distribution was 36 males and 19 females, and 40 cases of obstructive jaundice were seen in fifth, sixth, and seventh decades. 2. Causes of obstructive jaundice were 25 cases of pancreas cancer, 8 cases of common duct cancer, 4 cases of gallbladder cancer, 4 cases of ampulla vater cancer, 12 cases of common duct stone, and 2 cases of common duct stricture. 3. Levels of obstruction were 8 cases of hepatic portion, 15 cases of suprapancreatic portion, 28 cases of pancreatic portion, and 4 cases of ampullary portion. 4. In tumorous condition, CT demonstrated metastasis of other organs, 9 cases of the liver, 1 case of the lung, 3 cases of the pancreas, 3 cases of the common bile duct, 1 case of the stomach, and 12 cases of adjacent lymph nodes. 5. Associated diseases were 12 cases of intrahepatic stone, 4 cases of clonorchiasis, 2 cases of pancreas pseudocyst, 1 cases of hydronephrosis, and 1 case of renal cyst

Hans Selye in a note to Nature in 1936 initiated the field of stress research by showing that rats exposed to nocuous stimuli responded by way of a 'general adaptation syndrome' (GAS). One of the main features of the GAS was the 'formation of acute erosions in the digestive tract, particularly in the stomach, small intestine and appendix'. This provided experimental evidence for the view based on clinical data that gastro-duodenal (peptic) ulcers could be caused by stress. This hypothesis was challenged by Marshall and Warren's Nobel Prize (2005)-winning discovery of a causal association between Helicobacter pylori and peptic ulcers. However, clinical and experimental studies suggest that stress can cause peptic ulceration in the absence of H. pylori Predictably, the etiological pendulum of gastric and duodenal ulceration has swung from 'all stress' to 'all bacteria' followed by a sober realization that both factors play a role, separately as well as together. This raises the question as to whether stress and H. pylori interact, and if so, how? Stress has also been implicated in inflammatory bowel disease (IBD) and related disorders; however, there is no proof yet that stress is the primary etiological trigger for IBD. Central dopamine mechanisms seem to be involved in the stress induction of peptic ulceration, whereas activation of the sympathetic nervous system and central and peripheral corticotrophin-releasing factor appears to mediate stress-induced IBD. © 2017 Society for Endocrinology.

At present, selection of therapies for obstructive sleep apnea/hypopnea syndrome (OSAHS) relies on the localizing the obstructive sites and determination of its severity by polysomnography (PSG). Many methods have been applied to localize the obstructive sites. We attempted to evaluate the morphology of upper airway during sleep with dynamic MRI, and assessed the severity of OSAHS and results of therapies in groups classified by the patterns of obstructive sites. A categorizing system was set up, by which the obstructive sites were reviewed on axial and sagittal sections and accordingly classified into four patterns: front-to-back pattern, left-to-right pattern, circular pattern and epiglottis pattern. Comparison of apnea/hypopnea index (AHI), lowest SpO2 and BMI was performed between the different patterns. The results showed that the left-to-right pattern and circular pattern had a higher AHI and lower lowest SpO2, and more cases of obesity with higher BMI were found in these two groups. We also evaluated the results of different therapies for different obstructive site patterns. Radiofrequency coblation of soft palate was found to be effective for the front-to-back pattern. Improvement was found in 67% of all the cases that received uvulopalatopharyngoplasty (UPPP), while a significant postoperative improvement of AHI was confirmed in left-to-right pattern and circular pattern groups. No significant difference in the results was found between different obstructive sites or patterns when nasal continuous positive airway pressure (n-CPAP) was applied alone. Being completely free from CPAP (completed treatment with improvement of symptoms) was achieved in 71.4% of all the cases and 85.7% in the left-to-right pattern group who received UPPP. We conclude that an optimal treatment results could be achieved by selecting the therapies based on the severity of OSAHS and result of localizing the obstructive sites by dynamic MRI. (author)

Obstructive sleep apnea in chronic obstructive pulmonary disease patients.

Lee, Ruth

2012-02-01

PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) represent two of the most prevalent chronic respiratory disorders and cardiovascular diseases are major co-morbidities in both. Co-existence of both disorders (overlap syndrome) occurs in 1% of adults and overlap patients have worse nocturnal hypoxemia and hypercapnia than COPD and OSA patients alone. The present review discusses recent data concerning the pathophysiological and clinical significance of the overlap syndrome. RECENT FINDINGS: The severity of obstructive ventilatory impairment and hyperinflation, especially the inspiratory capacity to total lung capacity (TLC) ratio, correlates with the severity of sleep-related breathing disturbances. Early treatment with continuous positive airway pressure (CPAP) improves survival, reduces hospitalization and pulmonary hypertension, and also reduces hypoxemia. Evidence of systemic inflammation and oxidative stress in COPD and sleep apnea provides insight into potential interactions between both disorders that may predispose to cardiovascular disease. Long-term outcome studies of overlap patients currently underway should provide further evidence of the clinical significance of the overlap syndrome. SUMMARY: Studies of overlap syndrome patients at a clinical, physiological and molecular level should provide insight into disease mechanisms and consequences of COPD and sleep apnea, in addition to identifying potential relationships with cardiovascular disease.

Full Text Available Impairment of bone mineral density (BMD is frequent in celiac disease (CD patients on a gluten-free diet (GFD. The normalization of intestinal mucosa is still difficult to predict. We aim to investigate the relationship between BMD and duodenal mucosa healing (DMH in CD patients on a GFD. Sixty-four consecutive CD patients on a GFD were recruited. After a median period of a 6-year GFD (range 2–33 years, patients underwent repeat duodenal biopsy and dual-energy X-ray absorptiometry (DXA scan. Twenty-four patients (38% displayed normal and 40 (62% low BMD, 47 (73% DMH, and 17 (27% duodenal mucosa lesions. All patients but one with normal BMD (23 of 24, 96% showed DMH, while, among those with low BMD, 24 (60% did and 16 (40% did not. At multivariate analysis, being older (odds ratio (OR 1.1, 95% confidence interval (CI 1.03–1.18 and having diagnosis at an older age (OR 1.09, 95% CI 1.03–1.16 were associated with low BMD; in turn, having normal BMD was the only variable independently associated with DMH (OR 17.5, 95% CI 1.6–192. In older CD patients and with late onset disease, BMD recovery is not guaranteed, despite a GFD. A normal DXA scan identified CD patients with DMH; thus, it is a potential tool in planning endoscopic resampling.

It has recently been suggested that the inhalation of coal in the absence of complicated coal workers' pneumoconiosis (CWP) or smoking can lead to disabling airways obstruction. The cause of such obstruction has been variously attributed to emphysema or bronchitis. The frequency of significant airways obstruction in a group of United States coal miners seeking compensation for occupationally induced pulmonary impairment was therefore determined. In a sample of 611 "Black Lung" claimants there...

Objective: To determine eosinophil and mast cell populations in gastric and duodenal mucosal biopsies of adults with nonulcer dyspepsia (NUD) as compared to non-dyspeptic adults. Study Design: A case control study. Place and Duration of Study: Shahid Sadoughi University of Medical Sciences, Yazd, Iran, from January 2010 to June 2011. Methodology: A total of 52 (25 non-ulcer dyspeptic patients as case and 27 non-dyspeptic patients as control) patients underwent endoscopy. All patients had a minimum of 2 forceps biopsies obtained from stomach and duodenum. Routine histological evaluation was performed and additionally evaluated to determine eosinophil and mast cell counts. The statistical analysis was performed on SPSS version 17.0, using Mann-Whitney test with significance at p < 0.05. Results: The mean age in the case and control groups was 31.72 +- 12.17 and 35.74 +- 12.42 years respectively. The median eosinophil density in gastric mucosa in case group was 5.0 (ranging from 1 to 20) and 4.0 in control group (ranging from 0 to 16; p = 0.140). The median eosinophil density in duodenal mucosa in case group was 16.0 (ranging from 2 to 24) and 13 in control group (ranging from 2 to 45; p = 0.147). The median mast cell density in gastric mucosa in case group was 4.0 (ranging from 0 to 33) and 4.0 in control group (ranging from 0 to 26; p = 0.827). The median mast cell density in duodenal mucosa in case group was 4.0 (ranging from 0 to 31) and 3.0 in control group (ranging from 1 to 23; p = 0.704). The frequency of Helicobacter pylori infection in both the groups was similar. Conclusion: Although there were not statistically significant differences in eosinophil and mast cell densities between case and control groups, there was a trend toward mild eosinophilia in gastric and duodenal mucosa. The specific role of eosinophils and mast cells in NUD is yet to be completely defined. (author)

The incidence of peptic ulcer has steadily declined through out the world. This decreasing trend is also noticeable in this subcontinent. The point prevalence of peptic ulcer (PUD) in Bangladesh was around 15% in eighties. The aim of this study was to see the present prevalence of peptic ulcer at endoscopy and to identify changing trends in the occurrence of peptic ulcer in Bangladesh. This retrospective analysis of the endoscopic records of multiple tertiary referral centres of Dhaka city were done from January 2012 to July 2013. A total of 5608 subjects were the study samples. We included those patients having peptic ulcer in the form of duodenal ulcer, benign gastric ulcer including pre-pyloric ulcer and gastric outlet obstruction due to peptic ulcer. Duodenal ulcer and benign gastric ulcer were found in 415(7.4%) and 184(3.28%) patients respectively and gastric outlet obstruction due to peptic ulcer was found in 23(0.40%) patients.

To assess the significance of grade 1 hydronephrosis in the diagnosis of renal obstruction, the authors retrospectively reviewed the abdominal or renal US scans in 395 patients. In 80 patients there was a question of renal obstruction. Grade I hydronephrosis was observed in 33 of the 80 patients and obstruction was confirmed in more than 45% of these. In 315 patients, US was performed for reasons other than renal obstruction. Grade I hydronephrosis was observed in 39 of 315 patients, and obstruction was confirmed in less than 6%. The authors conclude that grade I hydronephrosis is significant when the question of renal obstruction exists. As an incidental finding, however, it is unlikely to represent obstruction. In the recent radiologic and medical literature grade I hydroephrosis is often dismissed as ''normal'' even in the clinical setting of obstruction. This trend is clearly not justified

Leucine (Leu), one of the three branch chain amino acids, acts as a signaling molecule in the regulation of overall amino acid (AA) and protein metabolism. Leucine is also considered to be a potent stimulus for the secretion of insulin from pancreatice β-cells. Our objective was to study the effects of a duodenal bolus infusion of Leu on insulin and glucagon secretion, on plasma AA concentrations, and to do a metabolomic profiling of dairy cows as compared to infusions with either glucose or saline. Six duodenum-fistulated Holstein cows were studied in a replicated 3 × 3 Latin square design with 3 periods of 7 days, in which the treatments were applied at the end of each period. The treatments were duodenal bolus infusions of Leu (DIL; 0.15 g/kg body weight), glucose (DIG; at Leu equimolar dosage) or saline (SAL). On the day of infusion, the treatments were duodenally infused after 5 h of fasting. Blood samples were collected at -15, 0, 10, 20, 30, 40, 50, 60, 75, 90, 120, 180, 210, 240 and 300 min relative to the start of infusion. Blood plasma was assayed for concentrations of insulin, glucagon, glucose and AA. The metabolome was also characterized in selected plasma samples (i.e. from 0, 50, and 120 min relative to the infusion). Body weight, feed intake, milk yield and milk composition were recorded throughout the experiment. The Leu infusion resulted in significant increases of Leu in plasma reaching 20 and 15-fold greater values than that in DIG and SAL, respectively. The elevation of plasma Leu concentrations after the infusion led to a significant decrease (Pcows were reduced (Pinsulin were not affected by Leu. In DIG, insulin and glucose concentrations peaked at 30-40 and 40-50 min after the infusion, respectively. Insulin concentrations were greater (Pcows were compared with the DIG and SAL cows at 50 and 120 min after the infusion. By using this analysis, several metabolites, mainly acylcarnitines, methionine sulfoxide and components from the

The duodenal ulcer (DU)-promoting gene (dupA) of Helicobacter pylori has been identified as a novel virulent marker associated with an increased risk for DU. The presence or absence of dupA gene of H. pylori present in patients with DU and functional dyspepsia in North Indian population was studied by polymerase chain reaction (PCR) and hybridization analysis. One hundred and sixty-six patients (96 DU and 70 functional dyspepsia) were included in this study. In addition, sequence diversity of dupA gene of H. pylori found in these patients was analyzed by sequencing the PCR products jhp0917 and jhp0918 on both strands with appropriate primers. PCR and hybridization analyses indicated that dupA gene was present in 37.5% (36/96) of H. pylori strains isolated from DU patients and 22.86% (16/70) of functional dyspepsia patients (p dupA was significantly associated with the cagA-positive genotype (p dupA gene with DU in this population. The dupA gene can be considered as a novel virulent marker for DU in this population.

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

The aim of this study was to evaluate impairment of acid-base balance (ABB) in acute obstructive uropathies. Evaluation of acid-base balance was performed by pH, partial carbon dioxide pressure, plasma bicarbonate concentration, buffer bases, basis excess, hydrogen ion concentration. An automatic gas analyzer was used, plasma anion gap was calculated. Characteristic ABB alterations in different acute obstructive uropathies were detected. Acidotic shifts in acute obstruction of the upper urinary tracts and its inflammatory complications were assessed pathophysiologically. A comparative study of pathological acid-base disorders in acute supra- and infravesical obstructive uropathies was performed.

Ureteral valve masquerading as obstructive megaureter

Directory of Open Access Journals (Sweden)

2017-05-01

Full Text Available Primary obstructed megaureter is a common urological condition in the pediatric age group. It is one of the differentials for congenital anomalies of the kidney and urinary tract that include a myriad of structural anomalies of the urinary tract. The obstructive conditions are usually managed conservatively unless there is deterioration in renal function, repeated urinary tract infection, or any other symptom such as abdominal pain on ipsilateral side and hypertension. Presented here is a case of left lower ureteral valve that was diagnosed as primary obstructed megaureter with pain in abdomen and reduced ipsilateral renal function wherein ureteral valve was detected incidentally intraoperatively. Excision of the valve with end to end uretero-ureteral anastomoses over a D-J stent, without resorting to ureteric reimplantation was successful in relieving the obstruction and hydronephrosis

Objective: To investigate the interventional therapy in children's congenital urinary obstruction and its efficacy. Methods: Thirty-three children with congenital obstruction of ureteropelvic junction were treated through percutaneous dilation and/or stent placement, and 42 cases with posterior urethral valves were treated through trans-urethra dilation. Results: Thirty-three cases with upper urinary obstruction were improved with symptoms disappeared and stable efficacy on long-term follow-up of 1-7 years. Another 2 cases with the upper urethral obstruction had not been relieved of symptoms and resorted to surgical operation. For patients with posterior urethral valves, the lower urethral obstruction was totally got rid of after interventional therapy with stable efficacy on long-term follow-up of 1-10 years. Conclusions: Interventional therapy is safe , micro-invasive and efficient in treating congenital urinary obstruction with stable efficacy on long-term follow-up. (authors)

Ultrasonography was performed on 44 dogs to decide whether small bowel obstruction was present. The sonographic criteria for small bowel obstruction were (1) the presence of pendulous movement of the ingesta inside the dilated bowel, (2) observation of invaginated intestines or an ingested intraluminal foreign body, (3) observation of non-uniform peristaltic activity of the dilated intestines, or (4) observation of akinetic intestinal loops together with abdominal fluid accumulation. By using these criteria, obstruction was correctly diagnosed by ultrasonography in 11 of the 13 dogs with mechanical ileus, and obstruction was correctly excluded in 29 of the 31 non-obstructive cases. Thus, the above-mentioned sonographic criteria had 85% sensitivity and positive predictive value, and 94% specificity and negative predictive value. The present study suggests that ultrasonography is a valuable tool for diagnosing small intestinal obstruction in the dog.

We have investigated the motility effects of acute experimental canine intestinal obstruction. A 30-min midjejunal obstruction was produced by clamping a Biebl loop or by inflating an intraluminal balloon. Spike bursts from serosal electrodes proximal to the site of obstruction increased markedly, while those from distal electrodes decreased. When the obstruction from an intraluminal Foley catheter was continued for 5.5 h, the inhibition persisted distally but the proximal contractile activity gradually fell to control levels. The reduced proximal activity after prolonged obstruction was largely due to clusters of regular intense spike bursts preceded and followed by lengthening periods of absent motor activity. Similar clustered contractions obliterated the lumen when the passage of barium through a Thiry-Vella loop was monitored fluoroscopically. Significant motility changes occur in intestinal obstruction, but an increased understanding of the mechanisms involved awaits future studies.

The endoscopic duodenal-jejunal bypass liner (DJBL) represents a novel temporary endoscopic approach for treatment of obesity-associated type 2 diabetes. Recent results from the German DJBL registry confirmed substantial positive metabolic effects of the DJBL in type 2 diabetes. However, the last Food and Drug Administration trial was stopped due to a high occurrence of hepatic abscesses (3.5%). Here, we analyzed time courses of development of co-morbidities, nutritive changes, and occurrence of adverse events during the 1-year treatment phase with the DJBL in the German DJBL registry. Sixty-six patients from the registry were analyzed for efficacy, safety, and nutritional status. Patient data sets were analyzed at implantation, 3 and 6 months after implantation, and at explantation visits. Weight, body mass index, glycated hemoglobin, and low-density lipoprotein cholesterol primarily declined during the first 3 months after implantation, whereas systolic and diastolic blood pressure were predominantly reduced during the second half of the treatment phase. Severe DJBL-associated side effects were mainly documented at the explantation visit (intestinal obstruction [1.7%], dislocation [1.7%], and liver abscess [1.7%]). Measurements of serum concentrations of ferritin, albumin, vitamin B12, folic acid, 25-hydroxyvitamin D3 (25 OH-Vit-D3), and calcium provided suggestive evidence of a possible decrease of nutritional absorption of vitamins and trace elements by the DJBL. The DJBL demonstrates high efficacy with substantial improvement of all parameters of the metabolic syndrome and the potential for reduction of comedications in overweight patients with type 2 diabetes. These registry results are important to optimize recommendations for adaptation of concomitant medication, surveillance of adverse events, nutritional status and supplementation, and adaptation of the implantation period of the DJBL.

To determine the correlation between CT measurements of emphysema or peripheral airways and airflow obstruction in chronic obstructive pulmonary disease (COPD). PubMed, Embase and Web of Knowledge were searched from 1976 to 2011. Two reviewers independently screened 1,763 citations to identify articles that correlated CT measurements to airflow obstruction parameters of the pulmonary function test in COPD patients, rated study quality and extracted information. Three CT measurements were accessed: lung attenuation area percentage < -950 Hounsfield units, mean lung density and airway wall area percentage. Two airflow obstruction parameters were accessed: forced expiratory volume in the first second as percentage from predicted (FEV{sub 1} %pred) and FEV{sub 1} divided by the forced volume vital capacity. Seventy-nine articles (9,559 participants) were included in the systematic review, demonstrating different methodologies, measurements and CT airflow obstruction correlations. There were 15 high-quality articles (2,095 participants) in the meta-analysis. The absolute pooled correlation coefficients ranged from 0.48 (95 % CI, 0.40 to 0.54) to 0.65 (0.58 to 0.71) for inspiratory CT and 0.64 (0.53 to 0.72) to 0.73 (0.63 to 0.80) for expiratory CT. CT measurements of emphysema or peripheral airways are significantly related to airflow obstruction in COPD patients. CT provides a morphological method to investigate airway obstruction in COPD.

Obstructive azoospermia represents approximately 10 % of cases of male hypofertility. It is classified according to the volume of ejaculate. When the latter is normal a proximal obstruction is suspected. Scrotal sonography can help to detect dilation of the epididymal head when clinical findings are equivocal. Ejaculatory duct obstruction (EDO) is suspected when the volume of ejaculate is low. The use of transrectal ultrasonography (TRUS) plays a major role in the investigation of these patients, and endorectal MRI is a very useful adjunct in selected cases. The most common cause of EDO is congenital bilateral absence of vas deferens, which is now thought to be a genital form of cystic fibrosis in 80 % of cases. Consequently, a definitive diagnosis must be made before any attempt at in vitro fertilization. TRUS accurately visualizes abnormalities of the caudal junction of the vas deferens and seminal vesicles, yielding a definitive diagnosis without scrototomy. Other causes of EDO are congenital cysts compressing the distal part of the ejaculatory ducts and inflammatory distal stenosis. The former are accurately identified by TRUS, but the latter give more or less marked signs of obstruction which are only of value in azoospermic patients with a low-volume ejaculate. More invasive imaging is required to diagnose partial obstruction of the ED. Surgical vasography is still the reference, but puncture of the seminal vesicles under TRUS guidance is an attractive alternative, as it permits aspiration of seminal fluid (to seek motile sperm) and vasography without scrototomy. Lastly, endorectal MRI well assesses the relationships between the proximal prostatic urethra and the posterior wall of the ejaculatory ducts, which need to be precisely known when endoscopic resection of the ejaculatory ducts is planned.

2015-01-01

Full Text Available Vast majority of bowel obstruction is due to postoperative adhesions, malignancy, intestinal inflammatory disease, and hernias; however, knowledge of other uncommon causes is critical to establish a prompt treatment and decrease mortality. Xanthomatosis is produced by accumulation of cholesterol-rich foamy macrophages. Intestinal xanthomatosis is an uncommon nonneoplastic lesion that may cause small bowel obstruction and several cases have been reported in the English literature as obstruction in the jejunum. We report a case of small intestinal xanthomatosis occurring in a 51-year-old female who presented with one day of copious vomiting and intermittent abdominal pain. Radiologic images revealed jejunal loop thickening and inflammatory changes suggestive of foreign body obstruction, diagnostic laparoscopy found two strictures at the jejunum, and a pathologic examination confirmed a segmental small bowel xanthomatosis. This case illustrates that obstruction even without predisposing factors such as hyperlipidemia or lymphoproliferative disorders.

Duodenal Villous Atrophy in a TTG-Negative Patient Taking Olmesartan: A Case Report and Review of the Literature

Full Text Available Olmesartan, an angiotensin II receptor antagonist used to treat hypertension, is associated with few adverse effects. Here, a case of severe sprue-like enteropathy and acute kidney injury is described in a 68-year-old male taking olmesartan for 3-4 years. He presented to hospital with a five-week history of diarrhea, vomiting, and a 20 lb weight loss. Anti-TTG was negative with a normal IgA. Biopsies of the distal duodenum and duodenal cap revealed marked blunting of the villi with near complete villous atrophy of the biopsies from the bulb. There was an increase in intraepithelial lymphocytes as well as neutrophils in the surface epithelium. The patient’s diarrhea improved upon discontinuation of olmesartan and he returned to his previous weight. Repeat endoscopy four months later demonstrated complete resolution of inflammatory change with normal villous architecture. Long-term olmesartan use is associated with severe sprue-like enteropathy. The mechanism of intestinal injury is unknown. Duodenal biopsy results may mimic other enteropathies such as celiac disease. Physicians should consider medications as potential etiologies of enteropathy.

Ruminant products are criticised for their SFA content relative to PUFA, although n-6:n-3 PUFA is desirable for human health ( content of rumen protozoa offers a potentially novel approach to enhance PUFA flow to the duodenum and subsequent incorporation into meat and milk. We evaluated protozoal contribution to duodenal n-3 PUFA flow due to intracellular chloroplast content. A total of six Holstein × Friesian steers were fed, in a two-period changeover design, either straw:concentrate (S:C, 60:40; DM basis; S:C, low chloroplast) or fresh perennial ryegrass (PRG; high chloroplast). Following 12 d adaptation to diet, ruminal protozoal and whole duodenal samples were obtained. N and fatty acid content of whole duodenum and rumen protozoal samples were assessed and protozoal 18S rDNA quantitative PCR performed, enabling calculation of protozoal N flow. The ratio of individual fatty acids:N in rumen protozoal samples was calculated to obtain protozoal fatty acid flows. Based on total fatty acid flow, contribution (%) of protozoa to individual fatty acid flows was calculated. Protozoal fatty acid data and microscopical observations revealed that protozoa were enriched with 18 : 3n-3 following PRG feeding, compared with the S:C diet, due to increased intracellular chloroplast content. However, duodenal protozoal 18S rDNA concentration post PRG feeding was low, indicating rumen retention of the protozoa. Nutrition influences the 18 : 3n-3 content of protozoa; the challenge is to increase protozoal flow to the small intestine, while maintaining sustainable rumen densities.

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. 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 5cm 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. 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. For the treatments of bezoar cases located in the small intestine, laparoscopic surgical method is a safe and feasible method in selected cases.

To determine the correlation between CT measurements of emphysema or peripheral airways and airflow obstruction in chronic obstructive pulmonary disease (COPD). PubMed, Embase and Web of Knowledge were searched from 1976 to 2011. Two reviewers independently screened 1,763 citations to identify articles that correlated CT measurements to airflow obstruction parameters of the pulmonary function test in COPD patients, rated study quality and extracted information. Three CT measurements were accessed: lung attenuation area percentage 1 %pred) and FEV 1 divided by the forced volume vital capacity. Seventy-nine articles (9,559 participants) were included in the systematic review, demonstrating different methodologies, measurements and CT airflow obstruction correlations. There were 15 high-quality articles (2,095 participants) in the meta-analysis. The absolute pooled correlation coefficients ranged from 0.48 (95 % CI, 0.40 to 0.54) to 0.65 (0.58 to 0.71) for inspiratory CT and 0.64 (0.53 to 0.72) to 0.73 (0.63 to 0.80) for expiratory CT. CT measurements of emphysema or peripheral airways are significantly related to airflow obstruction in COPD patients. CT provides a morphological method to investigate airway obstruction in COPD.

Obstructive sleep apnea syndrome has multifactorial causes. Although indications for surgery are evaluated by well-known diagnostic tests in the awake state, these do not always correlate with satisfactory surgical results. To undertake a systematic review on endoscopy during sleep, as one element of the diagnosis routine, aiming to identify upper airway obstruction sites in adult patients with OSAS. By means of electronic databases, a systematic review was performed of studies using drug-induced sleep endoscopy to identify obstruction sites in patients with OSAS. Ten articles were selected that demonstrated the importance of identifying multilevel obstruction, especially in relation to retrolingual and laryngeal collapse in OSAS. DISE is an additional method to reveal obstruction sites that have not been detected in awake patients. Copyright © 2015 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Directory of Open Access Journals (Sweden)

LIANG Zhang

2013-06-01

Full Text Available Obstructive jaundice, also known as surgical jaundice, is divided into benign and malignant types. Most of the patients newly diagnosed with malignant obstructive jaundice have lost the opportunity of receiving radical surgery due to its insidious onset, so surgical palliative treatment is very important for patients with advanced malignant obstructive jaundice. This paper elaborates on various current modalities of surgical palliative treatment for malignant obstructive jaundice. Appropriate modality of surgical palliative treatment is of great significance for patients with advanced malignant obstructive jaundice.

Obstructive sleep apnoea syndrome is associated with significant morbidity. A high prevalence of obstructive sleep apnoea (OSA) symptoms has been reported in patients with asthma and chronic obstructive pulmonary disease (COPD). There are limited studies regarding relationship between atopy and OSA. To study the risk of obstructive sleep apnoea among middle aged chronic obstructive pulmonary disease and asthma patients by a home based sleep study and its association with atopy. Patients with asthma and COPD were evaluated for OSA symptoms by Epworth sleepiness scale (ESS) and Berlin questionnaire (BQ). ESS score > or = 9 was considered as high risk for OSA. Patients having high risk for OSA by ESS and BQ were further evaluated for OSA by home based sleep study. Skin prick test against common allergens was done to diagnose atopy in these patients. Among 400 patients (229, 57.25% male and 171, 42.75% female) 328 were asthmatics and 72 were COPD patients. ESS and BQ was positive in 11.25% (45/400) and 18.25% (73/400) patients respectively. ESS was positive in 10.67% (35/328) of asthma and 13.88% (10/72) of COPD patients. BQ was positive in 18.29% (60/328) of asthmatic and 18.05% (13/72) of COPD patients. Skin prick test was positive in 74.16% patients. The maximum positivity was found in asthmatics (139/155, 89.68%) compared to COPD patients (16/155, 10.32%). Skin prick test was done for 40 patients out of 73 of Asthma and COPD patients who were found positive by ESS and BQ. 72.5% patients were found to be atopic. Out of 19 patients in whom home polysomnography was done, 13 patients consented for skin prick test with common aeroallergens and 9 (69.23%) patients were found to be atopic. There is an increased risk of obstructive sleep apnoea among middle aged chronic obstructive pulmonary disease and asthma patients. Atopy could be associated with OSA. The association needs to be proved in a larger study.

2003-01-01

Objective: To evaluate some specific CT and ERCP findings for differentiating the nature of biliary obstructive diseases. Methods: In total 85 cases of obstructive jaundice verified by pathology were selected. The CT findings in 45 cases and ERCP features in 68 cases were retrospectively analyzed. Results: Mild dilatation of intrahepatic bile ducts were usually found in benign diseases, while moderately or severely dilated intrahepatic bile ducts were revealed in malignancies. Dilatation of intrahepatic bile ducts in vine pattern was one of the characteristic signs of malignant lesions, while 'withered branches' dilatation was usually found in benign diseases. Dilated extra-hepatic bile duct abruptly narrowed or obstructed was a typical finding in malignancies, while gradual tapering of common bile duct at the obstructed level usually indicated benign nature of the disease. Conclusion: Both CT and ERCP are valuable modalities in locating and differential diagnosis of biliary obstruction. A combined evaluation improves the accuracy of diagnosis

Aminoazo dye-protein-adduct enhances inhibitory effect on digestibility and damages to Gastro-Duodenal-Hepatic axis.

Full Text Available 4-Dimethylaminoazobenzene (DAB, methyl yellow, or butter yellow, a human carcinogen, has been banned for use in foods since 1988. In 2014, DAB adulteration in Tofu occurred in Taiwan. We hypothesize that DAB can form [DAB•SBP]adduct adduct with soybean protein (SBP which could damage Gastro-Duodenal-Hepatic axis. Sprague-Dawley rats gavage fed [DAB•SBP]adduct adduct revealed severely reduced body weight and damaged duodenum, liver, hepatic mitochondria, and spleen. Hepatic levels of glutathione and ATP were severely reduced. Serum GOT and GPT were substantially elevated. Analysis by the adsorption isotherm clearly revealed DAB formed very stable [DAB•SBP]adduct adduct at 1:1 molar ration (Phase A. The equilibrium constant of this colloidal adduct [DAB•SBP]adduct was KeqA = ∝, behaving as the most stable and toxic species. At higher protein concentration (Phase C it formed conjugate [DAB×SBPgross]conjugate, with KeqC = 3.23×10-2 mg/mL, implicating a moderately strong adsorption. The in vitro pepsin digestibility test showed apparently reduced digestibility by 27% (by Ninhydrin assay or 8% (by Bradford assay. Conclusively, this is the first report indicating that [DAB•SBP]adduct potentially is capable to damage the Gastro-Duodenal-Hepatic axis.

Between Nov. 1994-Jan. 2001 we performed laparoscopic suture with omentoplasty of perforated duodenal ulcer (PDU) in 51 patients out of 56 it was intended (this constituted the laparoscopic group--LG). The selection criteria were young patients, age < 40 years, no associated diseases, onset of the operation under 12 hours from the occurrence of the perforation, absence of clear ulcer history. In the same period, we performed an open suture based on the same criteria in 105 patients (open group--OP). The results showed a difference between needed analgesia (2.8 days for LG vs. 5.2 days for OG) and a hospital stay of 6.1 days in LG vs. 7.7 days in OG. The incidence of postoperative complications was 5.88% in the LG and 7.61% in the OG with 1.96% and respective 1.90% reoperation rate. In conclusion laparoscopic suture of PDU with associated postoperative modern therapy of ulcer disease could be the treatment of choice in young patients.

Full Text Available Celiac disease is usually diagnosed by demonstrating gluten enteropathy in small bowel biopsy. Celiac specific antibodies are used as an initial screening test. The goal of this study is to test the relationship of the anti-tTG titer and severity of histological changes in Jordanian children with celiac disease. Method. The medical records of 81 children who had elevated anti-tTG titer and had duodenal biopsies available were retrospectively reviewed. Result. Assessing the association of anti-tTG titer with duodenal histopathological changes, 94% of those with high anti-tTG titer (≥180 U/mL had histological evidence of celiac disease. There was statistically significant positive association between high anti-tTG titer and Marsh grading as 82% of patients with Marsh III had high anti-tTG titer (Chi2 18.5; P value 0.00; Odds Ratio 8.5. The fraction of patients with Marsh III who were correctly identified as positive by anti-tTG titer ≥ 180 U/mL was high (sensitivity = 81.6. Moreover, the fraction of patients with anti-tTG titer ≥ 180 U/mL who had Marsh III was also high (positive predictive value = 78.4. Conclusion. Anti-tTG titer ≥ 180 U/mL had significant positive association with Marsh III histopathological changes of celiac disease.

The edible fruits of Pithecellobium dulce (Roxb.) Benth. are traditionally used for various gastric complications in India. Here, we investigated the antiulcer activity of hydroalcoholic fruit extract of P. dulce (HAEPD) by applying cysteamine induced duodenal ulcer model in rats. Duodenal ulcer was induced in male albino Wistar rats by oral administration of cysteamine @ 420 mg/kg body wt. as a single dose. The rats were pre-administered orally with HAEPD @ 200 mg/kg body wt. for 30 days prior to ulcer induction. Rats pre-administered with ranitidine @ 30 mg/kg body wt. served as reference drug control. Ulcer score, thiobarbituric acid reactive substances (TBARS), glycoproteins, superoxide dismutase, catalase and glutathione peroxidase and reduced glutathione levels were measured in the duodenum. Rats pre-administered with the HAEPD showed significantly reduced ulcer score comparable to that of ranitidine pretreated rats. The co-administration of HAEPD lowered the TBARS level and also restored the levels of glycoproteins, enzymatic and non-enzymatic antioxidants. Histopathological observations confirmed the presence of inflammation, necrosis and hemorrhagic spots in the duodenum of ulcer control rats which were significantly reduced due to HAEPD treatment. No abnormal alterations were observed in normal rats treated with HAEPD at the dosage studied. The results demonstrated antioxidant and cytoprotective nature of P. dulce, and thereby its significant anti ulcer property.

As recent advances in chemotherapy and surgical treatment have improved outcomes in patients with biliary cancers, the search for an optimal strategy for relief of their obstructive jaundice has become even more important. Without satisfactory relief of biliary obstruction, many patients would be ineligible for treatment. We review all prospective randomized trials and recent retrospective non-randomized studies for evidence that would support such a strategy. For distal malignant biliary obstruction, an optimal strategy would be insertion of metallic stents either endoscopically or percutaneously. Evidence shows that a metallic stent inserted percutaneously has better outcomes than plastic stents inserted endoscopically. For malignant hilar obstruction, percutaneous biliary drainage with or without metallic stents is preferred.

Anesthetics are variable in patients with obstructive jaundice. The minimum alveolar concentration awake of desflurane is reduced in patients with obstructive jaundice, while it has no effect on pharmacodynamics and pharmacokinetics of propofol. In this study, we investigated the influence of obstructive jaundice on the pharmacodynamics and blood concentration of rocuronium. Included in this study were 26 control patients and 27 patients with obstructive jaundice. Neuromuscular block of rocuronium was monitored by acceleromyography. Onset time, spontaneous recovery of the height of twitch first (T1) to 25% of the final T1 value (Duration 25%, Dur 25%), recovery index (RI), and spontaneous recovery of train-of-four (TOF) ratios to 70% were measured. The plasma rocuronium concentrations were determined by high performance liquid chromatography using berberine as an internal standard. There was no significant difference in onset time between the two groups. The Dur 25%, the recovery index and the time of recovery of the TOF ratios to 70% were all prolonged in the obstructive jaundice group compared with the control group. The plasma concentration of rocuronium at 60, 90 and 120 min after bolus administration was significantly higher in the obstructive jaundice group. The neuromuscular blockade by rocuronium is prolonged in obstructive jaundice patients, and therefore precautions should be taken in case of postoperative residual neuromuscular block. The possible reason is impedance of rocuronium excretion due to biliary obstruction and increased plasma unbound rocuronium because of free bilirubin competing with it for albumin binding.
