Post-bulbar duodenal ulcer with anterior perforation with kissing ulcer and duodenocaval fistula:A case report and review of literature

BACKGROUND A post-bulbar duodenal ulcer(PBDU)is an ulcer in the duodenum that is distal to the duodenal bulb.PBDU may coexist with a synchronous posterior ulcer in rare occurrences,resulting in a kissing ulcer(KU).Duodenocaval fistula(DCF)is another uncommon but potentially fatal complication related to PBDU.There is limited knowledge of the scenarios in which PBDU is complicated by KU and DCF simultaneously.CASE SUMMARY A 22-year-old man was admitted to the emergency department with abdominal pain,stiffness,and vomiting.The X-ray showed pneumoperitoneum,suggesting a perforated viscus.Laparotomy revealed a KU with anterior perforation and a DCF.After Kocherization,venorrahphy was used to control caval bleeding.Due to the critical condition of the patient,only primary duodenorrahphy with gastrojejunostomy was performed as a damage control strategy.However,later,the patient developed obstructive jaundice and leakage,and two additional jejunal perforations were detected.Due to the poor condition of the duodenum and the involvement of the ampulla in the posterior ulcer,neither primary repair nor pancreatic-free duodenectomy and ampull-oplasty/ampullary reimplantation were considered viable;therefore,an emergency pancreaticoduodenectomy was performed,along with resection and anastomosis of the two jejunal perforations.The patient had a smooth recovery after surgery and was discharged after 27 d.CONCLUSION The timely diagnosis of PBDU and radical surgery can aid in the smooth recovery of patients,even in the most complex cases.

Effect of Xiaokuiling Prescription on the Expression of HSP_(72) , HSP B in Gastric Mucosa of Patients with Helicobacter Pylori associated Duodenal Ulcer

In order to investigate the mechanism of Xiaokuiling prescription (XKL) in the treatment of Helicobacter pylori (HP) associated duodenal ulcer (DU) and the pathophysiologic role of heat shock proteins (HSPs) in the healing of ulcer, the expression of HSP 72 and HSP B in gastric mucosa was detected by using SABC immunohistochemistry method and processed by micro image analysis system. The method of Western blotting was used to measure the contents of HSP 72 and HSP B in the tissue emulsion of gastric mucosa. The results were as follows: (1) HSP 72 expression of the gastric mucosa in the treated group was obviously increased as compared with that in the control group ( P <0.05); (2) HSP B expression of the gastric mucosa in the treated group was significantly decreased as compared with that in the control group ( P <0.01). It was suggested that the increased expression of HSP 72 and the elimination of HP might be related to the mechanism of action of XKL. HSPs might play an pathological and physiological role in the process of healing of gastric ulcer.

Observation of the Effect of Triple Therapy on Duodenal Ulcer with HP Posity

Thirty-foar cases of duodenal ulcer with Hp osity weve treated with Ompeperazole, Amoxi-cillin and Tindazole, which were compared with 34 cases of Hp positive duodenal ulcer treated with omeperazole only. The duration of treatment were both one week and all the patients were re-examed at one month after treatment. The result showed that the huring rate of ulcers (HRU) in triple therapy group was 88. 2%, uhile that of the contr group was 82. 3%. No significant difference was observed in the two groups (p>0.05). Hp eradication rate (HER) in triple therapy group was 91. 7%, while that of the control group was 41. 1 %. There was significant difference between the HERs of the two gronps (p<0.01 ). In the 45 cases with Hp eradication, ulcers in 44 cases hared, with huring rate of 97. 8%. In the 23cases without Hp eradication, ulcers in 14 cases hured, with huring rate of 60. 9%. There was significant difference between these two gronps (p<0.05), which suggested the significant improvement of HRU of-ter Hp eradication. The triple therapy has the advantages such as high HRU, high rate of tolerance and no severe side effects. The therapy deserve recomrnendation clinically.

Duodenal ulcer caused by coil wiggle after digital subtraction angiography-guided embolization: A case report

BACKGROUND Acute gastrointestinal bleeding(GIB)is a life-threatening medical emergency with high morbidity and mortality.Transcatheter embolization with endovascular coils under digital subtraction angiography guidance is a common and effective method for the treatment of GIB with high technical success rates.Duodenal ulcers caused by coils wiggled from the branch of the gastroduodenal artery,which is a rare complication,have not previously been reported in a patient with right intrathoracic stomach.CASE SUMMARY A 62-year-old man had undergone thoracoscopy-assisted radical resection of esophageal cancer and gastroesophageal anastomosis 3 years ago,resulting in right intrathoracic stomach.He was admitted to the hospital 15 mo ago for dizziness and suffered acute GIB during his stay.Interventional surgery was urgently performed to embolize the branch of the gastroduodenal artery with endovascular coils.After 15 mo,the patient was re-admitted with a chief complaint of melena for 2 d,esophagogastroduodenoscopy and abdominal computed tomography revealed that some endovascular coils had migrated into the duodenal bulb,leading to a deep ulcer.Bleeding was controlled after conservative treatment.Seven months later,duodenal balloon dilatation was performed to relieve the stenosis after the removal of a few coils,and the patient was safely discharged with only one coil retained in the duodenum due to difficulties in complete removal and risk of bleeding.Mild melena recurred once during the long-term follow-up.CONCLUSION Although rare,coil wiggle after interventional therapy requires careful attention,effective precautionary measures,and more secure alternative treatment methods.

History of Helicobacter pylori,duodenal ulcer,gastric ulcer and gastric cancer

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.

The relation between HLA-DQA1 genes and genetic susceptibility to duodenal ulcer in Wuhan Hans

AIM To study the genetic susceptibility of HLA-DQA1 alleles to duodenal ulcer in Wuhan Hans.METHODS Seventy patients with duodenalulcer and fifty healthy controls were examinedfor HLA-DQA1 genotypes.HLA-DQA1 typing wascarried out by digesting the locus specificpolymerase chain reaction amplified productswith alleles specific restriction enzymes(PCR-RFLP),i.e.,Apal Ⅰ,Bsaj Ⅰ,Hph Ⅰ,Fok Ⅰ,Mbo Ⅱ and Mnl Ⅰ.RESULTS The allele frequencies of DQA1 * 0301and DQA1 * 0102 in patients with duodenal ulcerwere significantly higher and lower respectivelythan those in healthy controls(0.40 vs 0.20,P = 0.003,mcorret = 0.024)and(0.05 vs 0.14,P = 0.012,but Pcorret】0.05),respectively.CONCLUSION DQA1 * 0301 is a susceptiblegene for duodenal ulcer in Wuhan Hans,andthere are immunogenetic differences in HLA-DQA1 locus between duodenal ulcer patients andhealthy controls.

Efficacy of ilaprazole in the treatment of duodenal ulcers:A meta-analysis

AIM:To compare the efficacy and tolerance of ilaprazole compared with other proton pump inhibitors(PPIs)in the treatment of duodenal ulcer.METHODS:An electronic database search of Medline,Embase,the Cochrane controlled trials register,Web of Science,PubMed,and the Chinese Biomedical Literature Database(updated to July 2013),and manual searches were conducted.A meta-analysis of randomized controlled trials comparing the efficacy and tolerance of ilaprazole and other PPIs in the treatment of duodenal ulcers was performed.RESULTS:Five articles involving 1481 patients were included.The meta-analysis showed no difference in the4-wk healing rate between ilaprazole and other PPIs[89.7%vs 87.0%;relative risk(RR)=1.02;95%CI:0.98-1.06;Z=1.00;P=0.32].The results did not change in the sensitivity analyses.The meta-analysis indicated that the adverse effect rate in the ilaprazole group was lower than that in the control group,but the difference was not significant(9.7%vs 13.0%;RR=0.81;95%CI:0.60-1.07;Z=1.47;P=0.14).CONCLUSION:Ilaprazole is a highly effective and safe PPI in the treatment of duodenal ulcers.Ilaprazole can be recommended as a therapy for acid-related disorders,especially in Asian populations.

Management of duodenal ulcer bleeding resistant to endoscopy:Surgery is dead!

Acute massive duodenal bleeding is one of the most frequent complications of peptic ulcer disease.Endoscopy is the first-line method for diagnosing and treating actively bleeding peptic ulcers because its success rate is high.Of the small group of patients whose bleeding fails to respond to endoscopic therapy,increasingly the majority is referred for embolotherapy.Indeed,advances in catheter-based techniques and newer embolic agents,as well as recognition of the effectiveness of minimally invasive treatment options,have expanded the role of interventional radiology in the management of hemorrhage from peptic ulcers over the past decade.Embolization may be effective for even the most gravely ill patients for whom surgery is not a viable option,even when extravasation is not visualized by angiography.However,it seems that careful selection of the embolic agents according to the bleeding vessel may play a role in a successful outcome.The role of the surgeon in this clinical sphere is dramatically diminishing and will certainly continue to diminish in ensuing years,surgery being typically reserved for patients whose bleeding failed to respond all previous treatments.Such a setting has become extremely rare.

Mechanisms involved in Helicobacter pylori induced duodenal ulcer disease:an overview

Duodenal ulcer (DU) can be developed viaseveral different mechanisms.Hypersecretion ofgastric acid is,however,a common denominator.Amassive hypersecretion of acid can by itself evoke aDU,e.g.in the Zollinger-Ellison syndrome.Irrespective of the mechanism behind thedevelopment of a DU,powerful antisecretorytreatment will heal the ulcer and preventrecurrence.

Successful treatment of life-threatening bleeding from a duodenal posterior bulb peptic ulcer by an over-the-scope-clip

Bleeding of peptic ulcer at the posterior duodenal bulb still is a particular endoscopic challenge with increased risk of treatment failure and worse outcome.In this article,we report successful treatment of an actively bleeding peptic ulcer located at the posterior duodenal wall,using an over-the-scope-clip in the case of a 54-year-old male patient with hemorrhagic shock.Incident primary hemostasis was achieved and no adverse events occurred during a follow-up of 60 d.

Perforated duodenal ulcer:An unusual manifestation of allergic eosinophilic gastroenteritis

Spontaneous perforation of a duodenal ulcer secondary to allergic eosinophilic gastroenteritis(EGE) has not been previously reported. We present such a case in a teenager who presented with peritonitis. After exploration and operative repair of his ulcer, he continued to experience intermittent abdominal pain, and further evaluation revealed eosinophilic gastroenteritis in the setting of multiple food allergies. His EGE resolved after adhering to a restrictive diet. Both duodenal ulcers and EGE are very rarely seen in pediatric patients. EGE has a variable presentation depending on the layer(s) of bowel wall affected and the segment of the gastrointestinal tract that is involved. Once diagnosed, it may respond to dietary changes in patients with recognized food allergies, or to steroids in patients in whom an underlying cause is not identified. Our case highlights the need to keep EGE in the differential diagnosis when treating pediatric patients with duodenal ulcers. The epidemiology, pathophysiology, and treatment of EGE are also discussed, along with a review of the current literature.

Successful endovascular treatment of endoscopically unmanageable hemorrhage from a duodenal ulcer fed by a renal artery: A case report

A 52-year-old woman was admitted with hypovolemic shock. Emergency endoscopy revealed three hemorrhagic duodenal ulcers(all stage A1) with exposed vessels. Two ulcers were successfully treated by endoscopic clipping; however, the remaining ulcer on the posterior wall of the horizontal portion of the duodenum could not be clipped. Because her vital signs were rapidly worsening, we performed transcatheter arterial embolization(TAE) as it is less invasive than surgery. Computed tomography aortography showed that the duodenal hemorrhage was sourced from the lower branch of the right renal artery. In general, the duodenum is fed by branches from the gastroduodenal artery or superior mesenteric artery. However, this patient had three right renal arteries. The lower branch of the right renal artery at the L3 vertebral level was at the same level as the horizontal portion of the duodenum. Complete hemostasis was achieved by TAE using metallic coils and n-butyl-2-cyanoacrylate. After TAE, she recovered from the hypovolemic shock and was discharged from hospital. She has had no recurrence of the hemorrhagic duodenal ulcer for over 1 yr, and followup endoscopy showed no necrosis or stricture of the duodenum. Although she developed a small infarct of her right kidney, her renal function was satisfactory. In summary, the present case is the first reported case of hemorrhagic duodenal ulcer in which the culprit vessel was a renal artery that was successfully treated by TAE. Computed tomography aortography before TAE provides valuable information regarding the source of a duodenal hemorrhage.

Life threatening bleeding from duodenal ulcer after Roux-en-Y gastric bypass: Case report and review of the literature

Acute upper gastrointestinal bleeding is a rare, but serious complication of gastric bypass surgery. The inaccessibility of the excluded stomach restrains postoperative examination and treatment of the gastric remnant and duodenum, and represents a major challenge, especially in the emergency setting. A 59-year-old patient with previous history of peptic ulcer disease had an upper gastrointestinal bleeding from a duodenal ulcer two years after having a gastric bypass procedure for morbid obesity. After negative upper endoscopy finding, he was urgently evaluated for gastrointestinal bleeding. At emergency laparotomy, the bleeding duodenal ulcer was identified by intraoperative endoscopy through gastrotomy. The patient recovered well after surgical hemostasis, excision of the duodenal ulcer and completion of the remnant gastrectomy. Every general practitioner, gastroenterologist and general surgeon should be aware of growing incidenceof bariatric operations and coherently possible complications after such procedures, which modify patient's anatomy and physiology.

Hemorrhagic gastric and duodenal ulcers after the Great East Japan Earthquake Disaster

AIM:To elucidate the characteristics of hemorrhagic gastric/duodenal ulcers in a post-earthquake period within one medical district.METHODS:Hemorrhagic gastric/duodenal ulcers in the Iwate Prefectural Kamaishi Hospital during the 6-mo period after the Great East Japan Earthquake Disaster were reviewed retrospectively.The subjects were 27patients who visited our hospital with a chief complaint of hematemesis or hemorrhagic stool and were diagnosed as having hemorrhagic gastric/duodenal ulcers by upper gastrointestinal endoscopy during a 6-mo period starting on March 11,2011.This period was divided into two phases:the acute stress phase,comprising the first month after the earthquake disaster,and the chronic stress phase,from the second through the sixth month.The following items were analyzed according to these phases:age,sex,sites and number of ulcers,peptic ulcer history,status of Helicobacter pylori(H.pylori)infection,intake of non-steroidal anti-inflammatory drugs,and degree of impact of the earthquake disaster.RESULTS:In the acute stress phase from 10 d to 1mo after the disaster,the number of patients increased rapidly,with a nearly equal male-to-female ratio,and the rate of multiple ulcers was significantly higher than in the previous year(88.9%vs 25%,P<0.005).In the chronic stress phase starting 1 mo after the earthquake disaster,the number of patients decreased to a level similar to that of the previous year.There were more male patients during this period,and many patients tended to have a solitary ulcer.All patients with duodenal ulcers found in the acute stress phase were negative for serum H.pylori antibodies,and this was significantly different from the previous year’s positive rate of 75%(P<0.05).CONCLUSION:Severe stress caused by an earthquake disaster may have affected the characteristics of hemorrhagic gastric/duodenal ulcers.

Gender differences of low-dose aspirin-associated gastroduodenal ulcer in Japanese patients

AIM:To clarify the gender differences about the clini-cal features and risk factors of low-dose aspirin (LDA) (81-100 mg daily)-associated peptic ulcer in Japanese patients.METHODS: There were 453 patients under treatment with LDA (298 males, 155 females) who underwent esophagogastroduodenoscopy at the Department of Gastroenterology and Hepatology of Hiratsuka City Hospital between January 2003 and December 2007. They had kept taking the LDA or started treatmentduring the study period and kept taking LDA during the whole period of observation. Of these, 119 patients (87 males, 32 females) were diagnosed as having LDA-associated peptic ulcer. We examined the clinical factors associated with LDA-associated peptic ulcer in both sexes.RESULTS: A history of peptic ulcer was found to be the risk factor for LDA-associated peptic ulcer common to both sexes. In female patients, age greater than 70 years (prevalence ORs 8.441, 95% CI: 1.797-33.649, P = 0.0069) was found to be another significant risk fac-tor, and the time to diagnosis as having LDA-associat-ed peptic ulcer by endoscopy was significantly shorter than that in the male patients (P = 0.0050). CONCLUSION: We demonstrated gender differences about the clinical features and risk factors of LDA-asso-ciated peptic ulcer. Special attention should be paid to aged female patients taking LDA.

Gastroduodenal ulcer bleeding in elderly patients on low dose aspirin therapy

AIM To determine the clinical characteristics of elderly patients of hemorrhagic gastroduodenal ulcer on low-dose aspirin(LDA)therapy.METHODS A total of 1105 patients with hemorrhagic gastroduodenal ulcer treated in our hospital between January 2000 and March 2016 were grouped by age and drugs used,and these groups were compared in several factors.These groups were compared in terms of length of hospital stay,presence/absence of hemoglobin(Hb)decrease,presence/absence of blood transfusion,Forrest Ⅰ,percentage of Helicobacter pylori infection,presence/absence of underlying disease,and percentage of severe cases.RESULTS The percentage of blood transfusion(62.6%vs 47.7%,P<0.001),Hb decrease(53.8% vs 40.8%,P<0.001),and the length of hospital stay(23.5 d vs 16.7 d,P<0.001)were significantly greater in those on drug therapy.The percentage of blood transfusion(65.3%vs 47.8%,P<0.001),Hb decrease(54.2%vs 42.1%,P<0.001),and length of hospital stay(23.3 d vs 17.5 d,P<0.001)were significantly greater in the elderly.In comparison with the LDA monotherapy group,the percentage of severe cases was significantly higher in the LDA combination therapy group when elderly patients were concerned(16.1%vs34.0%,P=0.030).Meanwhile,among those on LDA monotherapy,there was no significant difference between elderly and non-elderly(16.1%vs 16.0%,P=0.985).CONCLUSION A combination of LDA with antithrombotic drugs or nonsteroidal anti-inflammatory drugs(NSAIDs)contributes to aggravation.And advanced age is not an aggravating factor when LDA monotherapy is used.

Analysis of Recent Cases of Postbulbar Duodenal Ulcer in Japan

Although the incidence of postbulbar duodenal ulcers is low, many complications occur, such as hemorrhage, stenosis and perforation, and there are many points to be paid attention to with regard to its pathology. A high acid level has been pointed out as a cause, but this is not conclusive, and its association with Helicobacter pylori (Hp) infection is also unclear. We investigated chronic cases excluding acute cases such as acute duodenal mucosal lesion we encountered between 2001 and 2015. Five cases corresponded, accounting for 1.4% of all chronic duodenal ulcer cases, and there were more male patients (four patients were male), as previously reported. All cases were solitary punched-out ulcer on the medial side near the superior duodenal flexure, and many complications were observed such as melena in all patients, narrowing in 2, and penetration in 1. No specific pathology, such as Crohn’s disease, vasculitis, or Zollinger-Ellison syndrome, was noted, no patient was previously medicated with NSAIDs or low dose aspirin, and 3 patients were infected with Hp. All cases were healed by proton pump inhibitor administration or gastric acid secretion-suppressing treatment with selective proximal vagotomy. Recurrence after Hp eradication occurred in all of the 3 Hp-infected patients, suggesting that involvement of Hp in the cause of disease is unlikely.

Protective effect and mechanisms of action of Mongolian medicine Sulongga-4 on pyloric ligation-induced gastroduodenal ulcer in rats

BACKGROUND Sulongga-4(SL-4)is a herbal formula used in traditional Mongolian medical clinics for the treatment of peptic ulcers and gastroenteritis,even though its pharmacological mechanism has not been well characterized.AIM To evaluate the protective effect and identify the mechanisms of action of SL-4 on gastroduodenal ulcer induced by pyloric ligation(PL)in rats.METHODS PL was performed to induce gastric and duodenal ulcers in rats,which were then treated with oral SL-4(1.3,2.6,or 3.9 g/kg per day)for 15 d.PL-induced gastroduodenal ulceration.Therapeutic effects were characterized by pathological and histological evaluations and inflammatory indicators were analyzed by enzyme-linked immunosorbent assay.Microarray analyses were conducted to identify gene expression profiles of gastroduodenal tissue in PL rats with or without SL-4 treatment.The candidate target genes were selected and verified by quantitative reverse transcription polymerase chain reaction(qRT-PCR).RESULTS SL-4 decreased histopathological features in the PL-induced ulcerated rats.SL-4 significantly (P < 0.05) decreased expression of tumor necrosis factor-α,interleukin (IL)-1β, IL-6, endotoxin, platelet-activating factor, and increasedprostaglandin E2 and epidermal growth factor in ulcer tissue. Microarray analysiswas used to identify a panel of candidate target genes for SL-4 acting on PLinducedulceration. Genes included some complement and coagulation cascadeand retinol metabolism pathways that are closely associated with inflammatoryresponses and gastric mucosal protective mechanisms. qRT-PCR showed thataltered expression of the selected genes, such as CYP2b2, UGT2b1, A2m, andMASP1 was consistent with the microarray results.CONCLUSIONSL-4 exerts protective effects against PL-induced gastroduodenal ulcers viareducing inflammatory cytokines and elevating expression of gastric acidinhibitory factors. Downregulation of CYP2b2 and UGT2b1 genes in retinolmetabolism and upregulation of A2m and MASP1 genes in the complement andcoagulation cascades pathways are possibly involved in SL-4-mediated protectionagainst gastroduodenal ulcer.
