Helicobacter pylori infection and perforated peptic ulcer prevalence of the infection and role of antimicrobial treatment

Preparation, Characterization, and Anti-Adhesive Activity of Sulfate Polysaccharide from Caulerpa lentillifera against Helicobacter pylori

In the gastric mucosa, chronic inflammation due to Helicobacter pylori infection promotes gastrocarcinogenesis. Polysaccharides of Caulerpa lentillifera are well-characterized by broad antimicrobial activity and anti-inflammatory potentials. The present study was undertaken to investigate whether the low molecular sulfate polysaccharides of C. lentillifera (CLCP) exhibit any anti-adhesive activity against H. pylori. After a hot water extraction and purification process, two purified polysaccharide fractions (CLCP-1 and CLCP2) were studied based on structural characterization and bioactivity determination. The results implied that except for the molar ratio, CLCP-1 and CLCP-2 contain high sulfate, mannose, galactose, xylose, glucose levels, and low protein levels. The molecular weight and Fourier transform infrared spectroscopy (FT-IR) assays confirmed that CLCP-1 and CLCP-2 are sulfate polysaccharides with an average molecular weight (Mw) of 963.15 and 648.42 kDa, respectively. In addition, CLCP-1 and CLCP-2 exhibited stronger antibacterial activity against H. pylori. CLCP-1 and CLCP-2 could significantly promote macrophage proliferation and decrease the production of nitric oxide (NO) through downregulated expression of inducible nitric oxide synthase (iNOS). Meanwhile, CLCP-1 and CLCP-2 in this study showed efficiently protected gastric adenocarcinoma (AGS) cells against H. pylori with the inhibition of the IL-8/NF-κB axis. These findings suggested the effect of Caulerpa lentillifera polysaccharides on H. pylori adhesion, a potential supply of nutrients for eradication therapy through the reduction of cell count and inflammation.

An Overview of Gastroduodenal Perforation

Gastroduodenal perforation may be spontaneous or traumatic and the majority of spontaneous perforation is due to peptic ulcer disease. Improved medical management of peptic ulceration has reduced the incidence of perforation, but still remains a common cause of peritonitis. The classic sub-diaphragmatic air on chest x-ray may be absent and computed tomography scan is a more sensitive investigation in the stable patient. The management of perforated peptic ulcer disease is still a subject of debate. The majority of perforated peptic ulcers are caused by Helicobacter pylori, so definitive surgery is not usually required. Perforated peptic ulcer is an indication for operation in nearly all cases except when the patient is asymptomatic or unfit for surgery. However, non-operative management has a significant incidence of intra-abdominal abscesses and sepsis. Primary closure is achievable in traumatic perforation, but the management follows the Advanced Trauma Life Support (ATLS) principles.

The Association Between Helicobacter Pylori and Perforated Gastroduodenal Ulcer

Background Although the role of Helicobacter pylori (H. pylori) is well known in peptic ulcer disease (PUD) etiology, its role in perforated peptic ulcer (PPU) is not well established. This study aimed to assess the role of H. pylori infection in patients with PPU and to compare it with its prevalence in patients with PUD. Methodology This prospective analytical study was conducted for two years. The study patients were classified into two groups: group I consisted of patients (n = 48) operated for PPU and group II were patients (n = 48) with PUD diagnosed by endoscopy. The study excluded patients with any previous anti-H. pylori treatment, gastric malignancy, conservative management of sealed PPU, and those with a diameter of perforation less than the diameter of endoscopic biopsy forceps. Blood samples were taken for H. pylori serology IgG (ELISA) test. The mucosal biopsy samples from both the groups were tested with a rapid urease test and modified Giemsa stain examination to detect H. pylori. Results The prevalence of H. pylori infection were significantly less in patients with PPU than with PUD: by rapid urease: 12.5% vs. 31.2%, p: 0.002; modified Giemsa stain: 10.4% vs. 31.2%, p: 0.012; and IgG serology: 50 % vs. 68.7%, p: 0.012, respectively. Alcohol and tobacco were significant risk factors (p: 0.002 vs. p: 0.002 respectively). However, nonsteroidal anti-inflammatory drugs (NSAIDs) use was not a significant risk factor for PPU (p: 0.083). Conclusion H. pylori infection was not significantly associated with PPU. Some other factors like alcohol intake and tobacco were also involved in perforation. We can conclude that H. pylori infection is not a risk factor for PPU.

Perforated peptic ulcer - an update

Peptic ulcer disease (PUD) affects 4 million people worldwide annually. The incidence of PUD has been estimated at around 1.5% to 3%. Perforated peptic ulcer (PPU) is a serious complication of PUD and patients with PPU often present with acute abdomen that carries high risk for morbidity and mortality. The lifetime prevalence of perforation in patients with PUD is about 5%. PPU carries a mortality ranging from 1.3% to 20%. Thirty-day mortality rate reaching 20% and 90-d mortality rate of up to 30% have been reported. In this review we have summarized the current evidence on PPU to update readers. This literature review includes the most updated information such as common causes, clinical features, diagnostic methods, non-operative and operative management, post-operative complications and different scoring systems of PPU. With the advancement of medical technology, PUD can now be treated with medications instead of elective surgery. The classic triad of sudden onset of abdominal pain, tachycardia and abdominal rigidity is the hallmark of PPU. Erect chest radiograph may miss 15% of cases with air under the diaphragm in patients with bowel perforation. Early diagnosis, prompt resuscitation and urgent surgical intervention are essential to improve outcomes. Exploratory laparotomy and omental patch repair remains the gold standard. Laparoscopic surgery should be considered when expertise is available. Gastrectomy is recommended in patients with large or malignant ulcer.

Acid-reducing vagotomy is associated with reduced risk of subsequent ischemic heart disease in complicated peptic ulcer: An Asian population study

Persistent exacerbation of a peptic ulcer may lead to a complicated peptic ulcer (perforation or/and bleeding). The management of complicated peptic ulcers has shifted from acid-reducing vagotomy, drainage, and gastrectomy to simple local suture or non-operative (endoscopic/angiographic) hemostasis. We were interested in the long-term effects of this trend change. In this study, complicated peptic ulcer patients who received acid-reducing vagotomy were compared with those who received simple suture/hemostasis to determine the risk of ischemic heart disease (IHD).This retrospective cohort study analyzed 335,680 peptic ulcer patients recorded from 2000 to 2006 versus 335,680 age-, sex-, comorbidity-, and index-year matched comparisons. Patients with Helicobacter pylori (HP) infection were excluded. In order to identify the effect of vagus nerve severance, patients who received gastrectomy or antrectomy were also excluded. The incidence of IHD in both cohorts, and in the complicated peptic ulcer patients who received acid-reducing vagotomy versus those who received simple suture or hemostasis was evaluated.The overall incidence of IHD was higher in patients with peptic ulcer than those without peptic ulcer (17.00 vs 12.06 per 1000 person-years), with an adjusted hazard ratio (aHR) of 1.46 based on multivariable Cox proportional hazards regression analysis controlling for age, sex, Charlson's comorbidity index, and death (competing risk). While comparing peptic ulcer patients with acid-reducing vagotomy to those with simple suture/hemostasis or those without surgical treatment, the aHR (0.58) was the lowest in the acid-reducing vagotomy group.Patients with peptic ulcer have an elevated risk of IHD. However, complicated peptic ulcer patients who received acid-reducing vagotomy were associated with reduced risk of developing IHD.

Sequential versus concomitant therapy for eradication of Helicobacter Pylori in patients with perforated duodenal ulcer: A randomized trial

OBJECTIVES

Comparison of Helicobacter pylori eradication rates, side effects, compliance, cost, and ulcer recurrence of sequential therapy (ST) with that of concomitant therapy (CT) in patients with perforated duodenal ulcer following simple omental patch closure.

METHODS

Sixty-eight patients with perforated duodenal ulcer treated with simple closure and found to be H. pylori positive on three months follow-up were randomized to receive either ST or CT for H. pylori eradication. Urease test and Giemsa stain were used to assess for H. pylori eradication status. Follow-up endoscopies were done after 3 months, 6 months, and 1 year to evaluate the ulcer recurrence.

RESULTS

H. pylori eradication rates were similar in ST and CT groups on intention-to-treat (ITT) analysis (71.43% vs 81.80%,P = 0.40). Similar eradication rates were also found in per-protocol (PP) analysis (86.20% vs 90%,P = 0.71). Ulcer recurrence rate in ST groups and CT groups at 3 months (17.14% vs 6.06%,P = 0.26), 6 months (22.86% vs 9.09%,P = 0.19), and at 1 year (25.71% vs 15.15%,P = 0.37) of follow-up was also similar by ITT analysis. Compliance and side effects to therapies were comparable between the groups. The most common side effects were diarrhoea and metallic taste in ST and CT groups, respectively. A complete course of ST costs Indian Rupees (INR) 570.00, whereas CT costs INR 1080.00.

CONCLUSION

H. pylori eradication rates, side effects, compliance, cost, and ulcer recurrences were similar between the two groups. The ST was more economical compared with CT.

Long-term effects of gastrectomy in patients with spirometry-defined COPD and patients at risk of COPD: a case-control study

OBJECTIVE

Comorbidities are characteristic of COPD. However, little is known about the secondary manifestations of COPD in the gastrointestinal tract. Therefore, we aimed to explore the long-term effects of gastrectomy in patients with spirometry-defined COPD or those at risk of COPD.

PARTICIPANTS

Subjects included 87 patients either with COPD or at risk of COPD (symptomatic) who underwent gastrectomy between December 2003 and October 2013 (group A), and 174 patients either with COPD or at risk of COPD, matched by age (±5 years), sex, and forced expiratory volume in 1 second (FEV1) as percentage of predicted (FEV1% predicted) (±5%) (group B).

METHODS

All patients underwent routine blood chemistry and pulmonary function tests, arterial blood gas analysis, 6-minute walk test (6MWT), high-resolution chest computed tomography scans, and nutritional assessments.

RESULTS

The mean duration postgastrectomy was 18.3±15.4 years. The mean FEV1 and FEV1% predicted were 2.07±0.76 L and 74.6±24.5%, respectively. Univariate analysis indicated that group A patients had significantly lower body mass index, fat-free mass index, and serum hemoglobin and albumin concentration (all P=0.00), and walked a significantly shorter distance in the 6MWT (P<0.05). Multivariate linear regression analysis for the distance in the 6MWT indicated that increased residual volume (RV) to total lung capacity (TLC) as percentage of predicted (%RV/TLC) alone was an independent and significant predictor of reduced distances in the 6MWT.

CONCLUSION

We concluded that nutritional insufficiency in patients with COPD (or those at risk of COPD) who previously underwent gastrectomy might lead to hyperinflation and consequently, decreased exercise capacity.

Chronic subclinical perforation of a duodenal ulcer presenting with an abdominal abscess in a patient with seronegative rheumatoid arthritis

Peptic ulcer disease has been a major problem since the turn of this century with high morbidity and mortality. Perforation is less common, with an estimated incidence of 7-10 per 100 000. We present a young woman with rheumatoid arthritis presenting with anaemia. On work up, she was found to have a chronic abdominal abscess secondary to subclinical perforation of a duodenal ulcer. After undergoing percutaneous drainage, she became haemodynamically unstable and was taken for surgical washout and jejunostomy tube placement. A week later she had a decrease in the size of the abscess and was discharged home with drain and tube feeds. At her follow-up a few weeks later, she was tolerating goal tube feeds.

Análise epidemiológica e emprego do teste rápido da urease em pacientes com úlcera péptica perfurada

OBJETIVO: Analisar o perfil epidemiológico de pacientes com úlcera péptica gastroduodenal perfurada e verificar se a presença do H. pylori nas secreções peritoneais e intraluminais desses pacientes pode ser avaliada pelo teste rápido da urease. MÉTODOS: Realizou-se estudo prospectivo, transversal, descritivo, com dados de pacientes atendidos em um hospital de abrangência regional, em portadores de úlcera péptica perfurada. Coletou-se, no transoperatório, amostras de líquido peritoneal (na proximidade da perfuração) e da secreção intraluminal, sendo encaminhadas para cultura e teste rápido de urease. RESULTADOS: Quatorze pacientes foram analisados. A média etária foi 41,06 anos, todos homens, brancos (71,4%), tabagistas (57,2%), IMC < 30 (85,7%), com história prévia de dispepsia (78,6%). Sorologia para H. pylori foi positiva em 84,6% dos casos. O teste rápido da urease foi positivo em 78,6% das amostras do tubo digestivo e em 42,8% das amostras da cavidade peritoneal; 41,6% foram positivos em ambos os locais, 50% somente na cavidade digestiva e 8,4% exclusivamente na cavidade peritoneal. Dos 11 pacientes com sorologia positiva para H. pylori 100% apresentaram positividade em pelo menos um dos sítios pesquisados. CONCLUSÃO: Verificou-se que a incidência foi menor que a esperada. Há associação significativa entre a infecção pelo H. pylori e a ocorrência de perfuração. A presença deste patógeno pode ser avaliada tanto pela sorologia quanto pela realização do teste rápido da urease do fluido coletado na cavidade peritoneal e na luz gástrica/duodenal.

Changes in the localization of perforated peptic ulcer and its relation to gender and age of the patients throughout the last 45 years

Background

Throughout recent decades there has been noticeable change in the incidence of peptic ulcer disease and its complications. The aim of the present study was to determine the character of changes over the last 45 years in the localization of perforation, in patient age, and in patient gender.

Methods

A group of 881 patients admitted to the Second Department of General Surgery in Krakow, Poland, from 1962 to 2006 were included in the study and constituted the material for the analysis. The study was divided into three time periods (1962–1976, 1977–1991, and 1992–2006) to allow statistical analysis of trends.

Results

The general incidence of perforations of peptic ulcer did not show changes; however, the percentage of women with perforated duodenal ulcer markedly increased. Patients with perforated stomach ulcer—regardless of gender—and females suffering from perforated duodenal ulcer were, on the average, about 10 years older than males with perforated duodenal ulcers. The mean age of male and female patients with perforated duodenal ulcer over the last 45 years showed an insignificant upward trend.

Conclusions

(1) The percentage of women with perforated duodenal ulcer continuously and statistically significantly rose. (2) Men with perforated duodenal ulcer were significantly younger than other patients. (3) The mean ages of male and female patients with perforated duodenal ulcer over the last 45 years showed an insignificant upward trend.

In vitro and in vivo anti-Helicobacter/Campylobacter activity of the aqueous extract of Enantia chlorantha

The aqueous extract of Enantia chlorantha Oliver (Annonaceae) stem bark, a plant widely used in Cameroon for the traditional treatment of gastritis and stomach problems, was assessed for in vitro and in vivo anti-Helicobacter/Campylobacter properties using the well diffusion assay, agar dilution assay, and killing rate determination. The in vitro activity was dose-dependent, and the same antimicrobial parameters (MAQ = 0.63 mg; MIC = 0.39 mg/mL; MBC = 1.56 mg/mL; ET(100) = 8 h) were obtained for both H. pylori and C. jejuni/coli. When the plasma active principle concentration equivalence was determined in vitro using plasma from rats exposed to a single dose (3000 mg/kg) of the extract, the peak absorption of E. chlorantha active principle against H. pylori occurred at 2 h. Plasma activity was nil 8 h after extract administration. The in vivo H. pylori eradication potency of the extract was assessed using mice infected with H. pylori. Antral mucus sample cultures from mice treated with E. chlorantha extract (500 and 1000 mg/kg for 3 days) did not yield any growth. The results suggest that in addition to its in vitro activity, E. chlorantha water extract also possesses in vivo antibiotic effects against H. pylori.

Peptic ulcer disease

Peptic ulcer disease had a tremendous effect on morbidity and mortality until the last decades of the 20th century, when epidemiological trends started to point to an impressive fall in its incidence. Two important developments are associated with the decrease in rates of peptic ulcer disease: the discovery of effective and potent acid suppressants, and of Helicobacter pylori. With the discovery of H pylori infection, the causes, pathogenesis, and treatment of peptic ulcer disease have been rewritten. We focus on this revolution of understanding and management of peptic ulcer disease over the past 25 years. Despite substantial advances, this disease remains an important clinical problem, largely because of the increasingly widespread use of non-steroidal anti-inflammatory drugs (NSAIDs) and low-dose aspirin. We discuss the role of these agents in the causes of ulcer disease and therapeutic and preventive strategies for drug-induced ulcers. The rare but increasingly problematic H pylori-negative NSAID-negative ulcer is also examined.

Review article: Helicobacter pylori-negative duodenal ulcer disease

BACKGROUND

Helicobacter pylori infection rates in duodenal ulcer (DU) patients may be lower than previously estimated.

AIM

To review the real prevalence of H. pylori-negative DUs and its possible causes.

METHODS

Bibliographical searches in MEDLINE looking for the terms 'H. pylori' and 'duodenal ulcer'.

RESULTS

Mean prevalence of H. pylori infection in DU disease, calculated from studies published during the last 10 years including a total of 16 080 patients, was 81%, and this figure was lower (77%) when only the last 5 years were considered. Associations with H. pylori-negative DU were: (1) False negative results of diagnostic methods, (2) NSAID use (21% in studies with <90% infection rate), (3) Complicated DU (bleeding, obstruction, perforation), (4) Smoking, (5) Isolated H. pylori duodenal colonization, (6) Older age, (7) Gastric hypersecretion, (8) Diseases of the duodenal mucosa, (9) Helicobacter'heilmanii' infection and (10) Concomitant diseases.

CONCLUSION

In patients with H. pylori-negative DU disease, one should carefully confirm that the assessment of H. pylori status is reliable. In truly H. pylori-negative patients, the most common single cause of DU is, by far, the use of NSAIDs. Ulcers not associated with H. pylori, NSAIDs or other obvious causes should, for the present, be viewed as 'idiopathic'. True idiopathic DU disease only exceptionally exists.

Refractory peptic ulcer disease

Refractory PUD is a diagnostic and therapeutic challenge. Optimal management of severe or refractory PUD requires a multidisciplinary team approach, using primary care providers, gastroenterologists, and general surgeons. Medical management has become the cornerstone of therapy. Identification and eradication of H pylori infection combined with acid reduction regimens can heal ulceration and also prevent recurrence. Severe, intractable or recurrent PUD and associated complications mandates a careful and methodical evaluation and management strategy to determine the potential etiologies and necessary treatment (medical or surgical) required.

Decreasing incidence of peptic ulcer complications after the introduction of the proton pump inhibitors, a study of the Swedish population from 1974-2002

Background

Despite a decreasing incidence of peptic ulcer disease, most previous studies report a stabile incidence of ulcer complications. We wanted to investigate the incidence of peptic ulcer complications in Sweden before and after the introduction of the proton pump inhibitors (PPI) in 1988 and compare these data to the sales of non-steroid anti-inflammatory drugs (NSAID) and acetylsalicylic acid (ASA).

Methods

All cases of gastric and duodenal ulcer complications diagnosed in Sweden from 1974 to 2002 were identified using the National hospital discharge register. Information on sales of ASA/NSAID was obtained from the National prescription survey.

Results

When comparing the time-periods before and after 1988 we found a significantly lower incidence of peptic ulcer complications during the later period for both sexes (p < 0.001). Incidence rates varied from 1.5 to 7.8/100000 inhabitants/year regarding perforated peptic ulcers and from 5.2 to 40.2 regarding peptic ulcer bleeding. The number of sold daily dosages of prescribed NSAID/ASA tripled from 1975 to 2002. The number of prescribed sales to women was higher than to males. Sales of low-dose ASA also increased. The total volume of NSAID and ASA, i.e. over the counter sale and sold on prescription, increased by 28% during the same period.

Conclusion

When comparing the periods before and after the introduction of the proton pump inhibitors we found a significant decrease in the incidence of peptic ulcer complications in the Swedish population after 1988 when PPI were introduced on the market. The cause of this decrease is most likely multifactorial, including smoking habits, NSAID consumption, prevalence of Helicobacter pylori and the introduction of PPI. Sales of prescribed NSAID/ASA increased, especially in middle-aged and elderly women. This fact seems to have had little effect on the incidence of peptic ulcer complications.

Helicobacter genotyping and detection in peroperative lavage fluid in patients with perforated peptic ulcer

INTRODUCTION AND OBJECTIVES

Certain Helicobacter pylori genotypes are associated with peptic ulcer disease; however, little is known about associations between the H. pylori genotype and perforated peptic ulcer (PPU). The primary aim of this study was to evaluate which genotypes are present in patients with PPU and which genotype is dominant in this population. The secondary aim was to study the possibility of determining the H. pylori status in a way other than by biopsy.

MATERIALS AND METHODS

Serum samples, gastric tissue biopsies, lavage fluid, and fluid from the nasogastric tube were collected from patients operated upon for PPU. By means of PCR, DEIA, and LIPA the presence of the "cytotoxin associated gene" (cagA) and the genotype of the "vacuolating cytotoxin gene" were determined.

RESULTS

Fluid from the nasogastric tube was obtained from 25 patients, lavage fluid from 26 patients, serum samples from 20 patients and biopsies from 18 patients. Several genotypes were found, of which the vacA s1 cagA positive strains were predominant. Additionally, a correlation was found between the H. pylori presence in biopsy and its presence in lavage fluid (p=0.015), rendering the latter as an alternative for biopsy. Sensitivity and specificity of lavage fluid analysis were 100% and 67%, respectively.

CONCLUSION

This study shows the vacA s1 cagA positive strain is predominant in a PPU population. The correlation found between the H. pylori presence in biopsy and its presence in lavage fluid suggests that analysis of the lavage fluid is sufficient to determine the H. pylori presence. Risks associated with biopsy taking may be avoided.

Is perforated marginal ulcer after the surgery of gastroduodenal ulcer associated with inadequate treatment for Helicobacter pylori eradication?

BACKGROUND

A marginal ulcer developing after an initial operation for gastroduodenal ulcer is a serious threat to the patient, and a challenge to surgeons. Helicobacter pylori is the primary cause of peptic ulcer disease. However, its role in ulcer recurrence, especially of marginal ulcer (MU), after peptic ulcer surgery is unclear. This study aimed to determine any association between H. pylori infection and perforated MU by comparing the prevalence of H. pylori and nonsteroidal anti-inflammatory drugs (NSAIDs) use in patients with perforated (PMU) and in those with nonperforated MU (NPMU).

STUDY DESIGN

The study retrospectively evaluated the records of 16 patients with PMU who underwent surgical treatment and 24 patients with NPMU who underwent medical treatment in Atatürk University, School of Medicine, Department of General Surgery and Gastroenterology, between January 1995 and December 2004.

RESULTS

The rate of H. pylori in the PMU group was significantly higher than that of the NPMU group (P < 0.01). There was a significant relationship between NSAID consumption and PMU compared with NPMU patients (P < 0.01). There was also a significant relationship between NSAID consumption and H. pylori and PMU (P < 0.01).

CONCLUSION

Eradication of H. pylori after the first PMU operation especially in cases with impaired hemodynamics, severe peritoneal contamination, and/or a diameter smaller than 1 cm and avoiding the use of NSAIDs will surely reduce the risk of relapsing ulcers.

Persistence of Helicobacter pylori infection in patients with peptic ulcer perforation

OBJECTIVE

In patients with perforated peptic ulcer (PPU) the convergence between the high eradication rate of Helicobacter pylori infection and low rates of ulcer relapse after treatment has been associated with reinfection by non-virulent strains. The objective of this study was to evaluate the persistence of infection by virulent H. pylori strains and ulcer recurrence in 33 patients with PPU one year after surgery and antimicrobial treatment.

MATERIAL AND METHODS

The histological evaluation and molecular detection of H. pylori cagA and ureA genes, vacA allelic types and the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analyses of the glmM gene products from antral mucosa specimens were performed initially, 2-5 months and 1 year after therapy.

RESULTS

The density of H. pylori colonization was temporarily decreased (p<0.05) 2-5 months after therapy. After one year, complete eradication was achieved in only 7 patients (23%) at histological examination and recurrent ulcers were found in 3/33 (9%) patients. The vacA s1a allelic type of cagA-positive strains persisted in 19/33 (58%) PPU patients with identical PCR-RFLP fingerprints in 8/9 (89%) of the patients.

CONCLUSIONS

In PPU patients with a low eradication rate of H. pylori infection after surgical and antimicrobial treatment, the frequent recrudescence of the infection is mostly caused by the persisting virulent strains of the cagA and vacA s1a subtypes. In the 1-year follow-up period the recurrent ulceration can be postponed just by the lowered colonization density of H. pylori after eradicative therapy.

Surgical management of perforated peptic ulcer disease

BACKGROUND

Surgery for perforated peptic ulcer disease is one of the most common emergency procedures carried out in the western world. The role of postoperative empiric Helicobacter Pylori eradication therapy is controversial.

METHODS

The clinical, operative and postoperative surveillance details of 84 consecutive patients who underwent surgery for perforated peptic ulcer were reviewed.

RESULTS

All patients underwent omentopexy +/- simple closure followed by proton pump therapy. Patients were followed-up for an average of 44 +/- 19 months. Females were older than male patients (59 +/- 20 vs. 46 + 17 years; p<0.05), presented with symptoms of a longer duration (17.9 +/- 16 vs. 8.9 +/- 9 hours; p=0.045) and had a higher mortality rate (18% vs 3%; p<0.05). Seventy-nine per cent of patients received postoperative empiric Helicobacter Pylori eradication therapy.

CONCLUSIONS

Surgery for perforated peptic ulcer is associated with a significant perioperative mortality rate. Elderly female patients are particularly at risk.
