ABSTRACT

BACKGROUND/AIMS: Upper gastrointestinal bleeding (UGIB) is a frequent medical issue. The primary risk factors for bleeding peptic ulcers are Helicobacter pylori infection and non-steroidal anti-inflammatory drugs. The association between acute gastric/duodenal ulcer and opium use has been previously proposed; however, there is no available data on endoscopic findings of patients with acute UGIB who use opium. MATERIALS AND METHODS: In the present descriptive cross-sectional study, endoscopic data of 50 consecutive patients with oral opium use and 50 consecutive patients without any opium use who were admitted for UGIB were recorded. The size (5-10 mm, 11-20 mm, or more than 20 mm), number (single, double, or multiple), and location of the ulcers (esophagus, gastric corpus including the fundus and body, antrum, angulus, or duodenum) were examined by endoscopy in both groups. RESULTS: Three or more ulcers were observed in 46% and 16% of patients with oral opium use and without opium use, respectively (P-value = 0.001). The rate of giant ulcers (> 20 mm) was significantly higher in patients who used oral opium (40% vs. 12%; P-value = 0.007). Esophageal ulcers were also more common in oral opium users (30%) than non-users (8%) with UGIB (P-value = 0.01). Nevertheless, the location of the ulcers between the two groups generally was not statistically different. CONCLUSIONS: This study has demonstrated that multiple, large peptic ulcers in GIB are potential complications of oral opium use. This could aid the needed modifications in the treatment protocol for these patients.

ABSTRACT

BACKGROUND Cameron lesions are linear erosions and ulcers on the crests of gastric mucosal folds in the neck of a hiatal hernia and can be difficult to diagnose and treat. This report is of a case of chronic iron deficiency in a 61-year-old woman with a late diagnosis of a Cameron lesion, who did not respond to a single treatment with the proton pump inhibitor (PPI) pantoprazole, but was then treated with oral poloxamer 407 with hyaluronic acid and chondroitin sulfate in addition to PPI. CASE REPORT We report the case of a 61-year-old women with recurrent iron-deficiency anemia, first diagnosed 40 years prior to her presentation at our Endoscopy Unit, and an ongoing melena. We discovered an intrahiatal gastric mucosal defect, which we at first treated with proton pump inhibitors and sucralfate. After a follow-up gastroscopy revealed the persistence of the lesion, we decided to incorporate into the treatment a gel-like substance containing, among others, hyaluronic acid and chondroitin sulfate, and observed that the lesion resolved completely. CONCLUSIONS This report highlights that Cameron lesions should be considered in patients with hiatal hernia who have iron-deficiency anemia and can be diagnosed on upper endoscopy. Further clinical studies are required to determine the role of combined poloxamer 407 with hyaluronic acid and chondroitin sulfate in the management of Cameron lesions.

ABSTRACT

BACKGROUND: Stress ulcer is a severe complication in critically ill patients and causes a high mortality. The proton pump inhibitor esomeprazole is widely applied in the treatment of stress ulcers because of its powerful acid suppression ability. However, the mechanism of stress ulcer and the precise gastroprotective effect of esomeprazole in stress ulcer remain unclear. PURPOSE: In the present study, the rats with water-immersed and restraint (WIR)-induced stress ulcer were used to further elucidate the anti-ulcerogenic capacity of esomeprazole in stress ulcer in addition to its anti-acid secreting ability. METHODS AND RESULTS: The rats were randomly divided into 5 groups: control group (NS), water-immersed and restraint group (WIR), high-dose application of esomeprazole plus stress ulcer-induced group (HE+WIR), low-dose application of esomeprazole plus stress ulcer-induced group (LE+WIR), and high-dose application of esomeprazole without stress ulcer-induced group (HE). Our study showed that the pretreatment of esomeprazole alleviated gastric tissue damage in both macroscopic and histopathological manifestations. Pretreatment of esomeprazole elevated the decline in PEG2 level affected by WIR; and it inhibited the secretion of gastric acid, gastrin and pepsin. Moreover, esomeprazole exerted its antioxidant effects by reducing malondialdehyde levels, enhancing the expressions of antioxidant factors like glutathione and superoxide dismutase (SOD) and reducing the compensatory transcriptional elevation of SOD1 gene. Esomeprazole also reduced the levels of MPO (myeloperoxidase), tumor necrosis factor (TNF)-α and interleukin (IL)-1ß according to its anti-inflammatory effects. We further explored the possible mechanism of esomeprazole pretreatment on stress ulcer and demonstrated that esomeprazole attenuated the high phosphorylation levels of nuclear factor kappa B (NF-κB) p65 and p38 MAPK, and decreased the NF-κB p65 nuclear translocation induced by WIR related stress ulcer. CONCLUSION: Our study provides some evidence that the esomeprazole pretreatment exerts gastroprotective effects in WIR-induced stress ulcer through not only its antisecretory effect but also its antioxidant effect by inactivating the p38 MAPK and NF-κB signaling pathways.

ABSTRACT

AIM: To evaluate whether non-steroidal anti-inflammatory drugs (NSAIDs)-induced gastropathy is a clinically predictive model of referred visceral hypersensitivity. METHODS: Gastric ulcer pain was induced by the oral administration of indomethacin to male, CD1 mice (n = 10/group) and then assessed by measuring referred abdominal hypersensitivity to tactile application. A diverse range of pharmacological mechanisms contributing to the pain were subsequently investigated. These mechanisms included: transient receptor potential (TRP), sodium and acid-sensing ion channels (ASICs) as well as opioid receptors and guanylate cyclase C (GC-C). RESULTS: Results showed that two opioids and a GC-C agonist, morphine, asimadoline and linaclotide, respectively, the TRP antagonists, AMG9810 and HC-030031 and the sodium channel blocker, carbamazepine, elicited a dose- and/or time-dependent attenuation of referred visceral hypersensitivity, while the ASIC blocker, amiloride, was ineffective at all doses tested. CONCLUSION: Together, these findings implicate opioid receptors, GC-C, and sodium and TRP channel activation as possible mechanisms associated with visceral hypersensitivity. More importantly, these findings also validate NSAID-induced gastropathy as a sensitive and clinically predictive mouse model suitable for assessing novel molecules with potential pain-attenuating properties.

ABSTRACT

Gastric ulcer is an important risk factor for human health globally. Camellia japonica (CJ) is a plant of which the fruits are used as traditional phytomedicine for inflammatory and immunomodulatory diseases; however, the underlying molecular mechanism has not been clarified. The present study aimed to investigate the immunopharmacological activities of Camellia japonica and validate its pharmacological targets. To evaluate the protective roles of Camellia japonica on LPS-induced inflammation in RAW 264.7 cells and HCl/EtOH-induced gastric ulcer in mice; we applied 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), nitric oxide (NO), reactive oxygen species (ROS), histopathology, malondialdehyde (MDA), quantitative real-time polymerase chain reaction (qPCR), immunohistochemistry (IHC), and western blot analyses. We also determined the total phenolic and flavonoid content of Camellia japonica which might possess antioxidant and anti-inflammatory properties. We found the production of NO and ROS in RAW 246.7 cells were both suppressed by Camellia japonica. Moreover, Camellia japonica mitigated the HCl/EtOH-induced oxidative stress in gastric mucosa via the reduction of lipid peroxidation and elevation of NO production. Gastric mucosal damages were prominently improved by Camellia japonica, as confirmed by the histopathological evaluation. The gene expression of inflammatory cytokines and enzymes TNF-α, IL-6, IL-1ß, iNOS, and COX-2 was notably downregulated by Camellia japonica. In addition, Camellia japonica markedly attenuated the MAPKs (ERK1/2, JNK, and p38) phosphorylation, COX-2 expression, and activation of transcription factor NF-κB and as well as phosphorylation and degradation of IκBα in gastric mucosa. Taken together, the intimated anti-inflammatory and gastroprotective mechanism of Camellia japonica is mediated by modulation of oxidative stress, inflammatory cytokines, and enzymes via suppression of MAPK/NF-κB signaling pathways.

ABSTRACT

In this study, we investigated the gastroprotective effect of an isopropanol extract from the aerial parts of Artemisia princeps (IPAP) and developed a gastroretentive floating tablet of IPAP (IPAP-FR) for maximized local gastroprotective effects. Pre-treatment with IPAP ameliorated the gastric mucosal hemorrhagic lesions in ethanol/HCl- or indomethacin- treated rats. IPAP decreased mucosal hemorrhage of gastric ulcers induced by ethanol or indomethacin plus pyloric ligation in rats. The optimized floating tablet, IPAP-FR, floated on medium surface with more sustained eupatilin release compared to the non-floating control tablet. X-ray photographs in beagle dogs showed that IPAPFR was retained for > 2 h in the stomach. In the ethanol-induced gastric ulcer rat model, the gastric hemorrhagic lesion was improved more substantially with IPAP-FR compared to the non-floating control tablet. Based on these data, our data suggest that IPAP-FR has an improved therapeutic potential for the treatment of gastric ulcer.

ABSTRACT

Introducción: el D‒002, una mezcla de alcoholes de la cera de abejas, efectivo en modelos de osteoartritis y para reducir los síntomas de la misma. A diferencia de los medicamentos antiinflamatorios clásicos el D‒002 produce efectos gastroprotectores más que efectos gastrotóxicos. El Lyprinol, usado para disminuir la inflamación y los síntomas artríticos, mejora los síntomas de disfunción gastrointestinal en sujetos con dicha enfermedad. D‒002 y Lyprinol inhiben las actividades de cyclooxigenasa y 5‒lipooxigenasa, y son similarmente efectivos para reducir la inflamación en modelos experimentales. Objetivo: comparar los efectos del D‒002 y el Lyprinol sobre la mucosa gástrica de ratas normales y de ratas con úlcera gástrica inducida experimentalmente. Métodos: se determinó el índice de úlcera en ratas normales y en ratas con úlceras gástricas inducidas por etanol e inducidas por ligadura de píloro, en las cuales se midió el volumen gástrico y la secreción de mucus. Las ratas normales se distribuyeron en un grupo control (vehículo), uno con ácido acetil salicílico (150 mg/kg), tres con D‒002 y tres con Lyprinol; las ratas con úlcera inducida por etanol en un grupo control (vehículo), tres con D‒002 y tres con Lyprinol; y el experimento con ligadura...(AU)


Introduction: D-002, a mixture of beeswax alcohols, has been effective in osteoarthritis models and for reducing osteoarthritis symptoms. Unlike the classic anti-inflammatory drugs, D-002 elicits gastroprotective rather than gastrotoxic effects. Lyprinol, used for ameliorating inflammation and arthritic symptoms, improves gastrointestinal dysfunction symptoms in osteoarthritis subjects. Both D-002 and Lyprinol inhibit cyclooxygenase and 5?lipoxygenase activities, and have been similarly effective for reducing inflammation experimentally. Objective: to compare the effects of D-002 and Lyprinol on gastric mucosa of normal and experimentally-induced ulcer rats. Methods: ulcer indexes were measured in normal rats and in rats with ethanol or pylorus ligation-induced ulcers, in which gastric volume and mucus secretion were also measured. Normal rats were randomized into a vehicle control, one acetic salicylic acid (150 mg/kg), three D-002, three Lyprinol groups; rats with ethanol-ulcers into a vehicle control, three D-002 and three Lyprinol-treated groups; and the experiment on pylorus ligation included a negative control and eight pylorus-ligated...(AU)

ABSTRACT

PURPOSE: To compare the therapeutic effects of different doses of intravenous esomeprazole on treating trauma patients with stress ulcer bleeding. METHODS: A total of 102 trauma patients with stress ulcer bleeding were randomly divided into 2 groups: 52 patients were assigned to the high-dose group who received 80 mg intravenous esomeprazole, and then 8 mg/h continuous infusion for 3 days; 50 patients were assigned to the conventional dose group who received 40 mg intravenous esomeprazole sodium once every 12 h for 72 h. RESULTS: Compared with the conventional dose group, the total efficiency of the high-dose group and conventional dose group was 98.08% and 86.00%, respectively (p < 0.05), the hemostatic time was 22.10 h ± 5.18 h and 28.27 h ± 5.96 h, respectively (p < 0.05). CONCLUSION: Both doses of intravenous esomeprazole have good hemostatic effects on stress ulcer bleeding in trauma patients. The high-dose esomeprazole is better for hemostasis.

ABSTRACT

BACKGROUND: The incidence of upper gastrointestinal bleeding from stress ulcers has decreased within the last 30 years. Improvements in intensive care medicine including advanced equipment for artificial ventilation, better sedoanalgesic therapies, and the use of stress ulcer prophylaxis are credited for the decline. OBJECTIVES: To determine the effectiveness of proton pump inhibitors (PPIs) on gastric pH in patients exposed to a defined severe stress situation during a specified time period. METHODS: Prospective open study in a tertiary community hospital. A high dose (80 mg bolus followed by 8 mg/h) of either pantoprazol or omeprazol was infused in 17 patients with opiate dependence who were undergoing ultra-rapid opiate withdrawal by barbiturate anesthesia. MEAN OUTCOME MEASURE: Gastric pH. RESULTS: Gastric pH did not change significantly in the majority of patients (mean pH 1.2 ± 0.9 immediately before, 1.5 ± 1.6 at 60 min after, and 1.3 ± 1.5 at 120 min after PPI infusion began). Gastric pH increased temporarily in two of the nine patients receiving omeprazol. In two of the eight patients, pantoprazol led to a late but sustained increase in gastric pH (pH 3.9 and 6.0 at 120 min post infusion). CONCLUSION: High doses of PPIs are ineffective in elevating gastric pH in patients exposed to severe stress such as ultra-rapid opiate detoxification. Therefore, adequate sedoanalgesia might be the main factor responsible for preventing stress-related bleeding in critically ill patients.

ABSTRACT

We report a case series of all consecutive patients hospitalized in our two tertiary referral medical centers over the past 17 years for Cameron ulcers causing severe upper gastrointestinal hemorrhage (GIH) or severe obscure GIH. Cameron ulcers were diagnosed in 25 of the 3960 screened patients with severe upper GIH or severe obscure GIH (0.6 %). Of these, 21 patients had a prospective follow-up (median time 20.4 months [interquartile range: 8.5 - 31.8]). Patients were more often elderly women with chronic anemia, always had large hiatal hernias, and were usually referred for obscure GIH. Twelve of the 21 patients (57 %) were referred for surgery while being treated with high-dose proton pump inhibitors (PPIs). The other 9 patients (43 %) continued PPIs without any rebleeding during the follow-up. Cameron ulcers in large hiatal hernias are an uncommon cause of severe upper GIH. The choice of medical vs. surgical therapy should be individualized.

ABSTRACT

Parkinson's disease is one of the most frequent progressive degenerative disorders with unknown origin of the nervous system. The commutation of the disease on Guam led to the discovery of a neurotoxin which was also found in other continents. This neurotoxin was identified in the common cyanobacteria (blue-green algae). Early clinical observations suggested some loose correlations with gastric and duodenal ulcer and Parkinson's disease, while recent studies revealed a toxin, almost identical to that found in cyanobacteria in one strain of Helicobacter pylori, which proved to cause Parkinson like symptoms in animals. Therefore, it cannot be ruled out that there is a slowly progressive poisoning in Parkinson's disease. The disease specific alpha-sinuclein inclusions can be found in nerve cells of the intestinal mucosa far before the appearance of clinical symptoms indicating that the disease may start in the intestines. These results are strengthened by the results of Borody's fecal transplants, after which in Parkinson patients showed a symptomatic improvement. Based on these observations the Parkinson puzzle is getting complete. Although these observations are not evidence based, they may indicate a new way for basic clinical research, as well as a new way of thinking for clinicians. These new observations in psycho-neuro-immunology strengthen the fact that immunological factors may also play a critical factor facilitating local cell necrosis which may be influenced easily.

ABSTRACT

OBJECTIVE: To study the comparative gastroprotective effect of Luffa acutangula methanolic extract (LAM) and aqueous extract (LAW) on type II diabetes rats. METHODS: Streptozotocin (65 mg/kg, i.p.) along with nicotinamide (120 mg/kg, i.p.) was used to induce non insulin dependent diabetes mellitus (NIDDM) in rats. A daily oral dose of aspirin (200 mg/kg, i.p.) was administered for initial seven days to induce gastric ulcerations in the diabetic rats. LAM and LAW were administered orally in the doses of 100, 200 and 400 mg/kg once daily for 21 days. Glibenclamide and ranitidine were used as standards for comparing the antidiabetic and antiulcer effect respectively. RESULTS: LAM significantly (P<0.01) increased mucosal glycoprotein and antioxidant enzyme level in gastric mucosa of diabetic rats than LAW (P <0.05). LAM was efficient in reversing the delayed healing of gastric ulcer in diabetic rats close to the normal level. LAM exhibited better ulcer healing effect than glibenclamide and LAW, because of its both antihyperglycemic and mucosal defensive actions. CONCLUSIONS: Thus, LAM is proved to be a better alternative for treating gastric ulcers co-occurring with diabetes.

ABSTRACT

Osteopoikilosis (OPK) is a rare disease with an unknown etiology. Although a benign condition, it may lead to diagnostic problems when the patient undergoes diagnostic imaging of the skeletal system due to various reasons like malignancy. Herein, we report 2 cases with OPK causing difficulties in the final diagnosis of the cases which was resolved with the contribution of bone scintigraphy and clinical follow-up.

ABSTRACT

INTRODUCTION: Cameron lesions are linear gastric ulcers or erosions positioned on the crests of mucosal folds at the diaphragmatic impression, in patients with large hiatal hernia, and can cause iron deficiency anaemia. CASE REPORT: We present a case of a 56-year-old woman who was referred to our institution for further investigation after she was examined in gastroenterology emergency room (GER) for signs and symptoms of severe hypochromic microcytic anemia without signs of acute gastrointestinal bleeding and with no obvious cause of chronic blood loss. Endoscopy showed linear ulceration at the level of diaphragm-Cameron lesions with large hiated hernia. She was treated with proton pump inhibitors and iron supplements. The laparoscopic fundoplication was done. Six months later she was asymptomatic. CONCLUSION: Large hiatus hernia may cause iron deficiency anemia due to occult bleeding from Cameron erosions. The current therapy concept includes the surgical reconstruction of the hiatus together with gastric fundoplication in combination with the proton pump inhibitor therapy.

ABSTRACT

BACKGROUND: Elevation of the gastric pH increases the risk for sensitization against food allergens by hindering protein breakdown. This can be caused by acid-suppressing medication like sucralphate, H2-receptor blockers and proton pump inhibitors, as shown in recent murine experimental and human observational studies. OBJECTIVE: The aim of the present study was to assess the sensitization capacity of the dietary supplement base powder and of over-the-counter antacids. METHODS: Changes of the pH as well as of protein digestion due to base powder or antacids were measured in vitro. To examine the in vivo influence, BALB/c mice were fed codfish extract with one of the acid-suppressing substances. Read-out of antibody levels in the sera, of cytokine levels of stimulated splenocytes and of intradermal skin tests was performed. RESULTS: The pH of hydrochloric acid was substantially increased in vitro by base powder as well as antacids in a time- and dose-dependent manner. This elevation hindered the digestion of codfish proteins in vitro. A significant increase in codfish-specific IgE antibodies was found in the groups fed codfish combined with Rennie Antacidum or with base powder; the latter also showed significantly elevated IgG1 and IgG2a levels. The induction of an anaphylactic immune response was proven by positive results in intradermal skin tests. CONCLUSIONS: Antacids and dietary supplements influencing the gastric pH increase the risk for sensitization against allergenic food proteins. As these substances are commonly used in the general population without consulting a physician, our data may have a major practical and clinical impact.

ABSTRACT

Cameron lesions are linear gastric ulcers or erosions on the mucosal folds at the diaphragmatic impression in patients with a large hiatal hernia. The lesions are associated with occult bleeding and development of chronic iron deficiency anaemia, but are often overlooked during routine endoscopy. We present two patients with known hiatal hernias in who repeated endoscopic examinations had not been able to identify a source of bleeding. In both cases, typical Cameron lesions were found either by repeat gastroscopy or by capsule endoscopy. Treatment with high-dose proton pump inhibitor and iron supplement was initiated.

ABSTRACT

It was reported previously that non-steroidal anti-inflammatory drugs (NSAID)-induced gastric damage was markedly aggravated in rats during arthritis, and this response was mediated by the overproduction of nitric oxide (NO) derived from endothelial NO synthase (eNOS) in addition to inducible NO synthase (iNOS). The present study examined the gastric ulcerogenic response to cold-restraint stress in adjuvant arthritic rats, particularly in relation to NO/NOS isozymes. Exposure of normal rats to cold-restraint stress (13 degrees C) produced slight gastric damage 3 h later, but the ulcerogenic response was markedly aggravated in arthritic rats. Pretreatment with N(G)-nitro-L-arginine methyl ester (L-NAME) (a nonselective inhibitor of NOS) slightly increased the cold-restraint stress-induced gastric lesions in normal rats, but dose-dependently prevented the aggravation of these lesions in arthritic rats. The increased ulcerogenic response in arthritic rats was significantly suppressed by 1400 W (a selective inhibitor of iNOS) and L-iminoethyl ornithine (L-NIO) (a selective inhibitor of eNOS), but not by N(G)-propyl-L-arginine (L-NPA) (a selective inhibitor of nNOS), and almost totally abolished by the co-administration of 1400 W and L-NIO. The mucosal expression levels of eNOS and iNOS but not nNOS mRNAs were enhanced in arthritic rats compared with normal rats. The aggravation of stress-induced gastric lesions in arthritic rats was also significantly suppressed by pretreatment with glutathione. These results suggest that the gastric ulcerogenic response to cold-restraint stress is enhanced in arthritic rats, similar to that induced by NSAIDs, and this phenomenon may be causally associated with the upregulation of eNOS/NO in addition to iNOS/NO.

ABSTRACT

Diabetes has been reported to cause an increase in offensive and decrease in defensive gastric mucosal factors, the imbalance of which can cause ulceration and delay the ulcer healing. Eugenia jambolana has been documented to have both antidiabetic and antiulcer activities. The present study evaluates the effects of ethanolic extract of E. jambolana on gastric ulcer healing and on rat gastric mucosal defensive factors in gastric ulcer with co-occurring diabetes. E. jambolana extract was administered orally in the dose of 200 mg/kg once daily for 10 days. E. jambolana extract increased mucin secretion, mucosal glycoprotein and glutathione levels and decreased the lipid peroxidation in gastric mucosa of diabetic rats. Its treatment also reversed the decrease in life span of gastric mucosal cells as indicated by decreased cell shedding in the gastric juice but found to have no effect on cell proliferation, indicating enhanced defensive status. E. jambolana extract was effective in reversing the delayed healing of gastric ulcer in diabetic rats near to the normal level. E. jambolana showed better ulcer healing effect than glibenclamide, because of its both antihyperglycemic and mucosal defensive actions. It could thus, be a better choice for treating gastric ulcers co-occurring with diabetes.

ABSTRACT

La perforación de una úlcera péptica corresponde a una infrecuente y siempre grave complicación de la enfermedad ulcerosa. El tratamiento quirúrgico es la terapia de elección. Se operaron 22 pacientes (21 hombres) con una edad promedio de 50 años. Tres enfermos tenían el diagnóstico de úlcera péptica previo a la emergencia actual. El síntoma más frecuente de consulta fue el dolor epigástrico de inicio súbito en 21 (95,4 por ciento) pacientes. El diagnóstico se realizó con radiografía de tórax de pie o de abdomen simple en 11 enfermos. Se realizó sutura simple de la úlcera en 12 (54,5 por ciento) pacientes, sutura más epiploplastía en 7 (31,8 por ciento) y resección gástrica en tres enfermos (13,6 por ciento). Siete (31,8 por ciento) pacientes presentaron complicaciones post operatorias, de los cuales fallecieron 2 (9,1 por ciento) como consecuencia de la sepsis asociada. Se realizó un seguimiento endoscópico a 9 pacientes (45 por ciento) sobrevivientes al episodio agudo. En 5 de ellos se demostró que la úlcera péptica aun permanecía activa. A dos de estos últimos pacientes se les realizó, en forma electiva una cirugía resectiva definitiva. Se concluye que la perforación de una úlcera péptica corresponde a un cuadro grave, que se asocia a una morbilidad y mortalidad significativa. El tratamiento quirúrgico local es la terapia de elección para el episodio agudo, sin embargo este no es definitivo y no evita la recidiva.


Background: Peptic ulcer perforation is an uncommon by devastating complication that requires emergency surgical treatment. Aim: To review the results of surgical treatment of peptic ulcer perforation in a Chilean Regional Hospital. Material and Methods: Retrospective review of medical records of 22 patients (age range 21-88 years, 21 males) operated for a perforated peptic ulcer, between 1995 and 2000. Results: The most common presentation symptom was acute epigastric pain in 21 patients. The diagnosis was done with a plain abdominal X ray obtained in the standing position, in 11 patients. A simple suture of the ulcer was done in 12 patients, suture plus epiploplasty in seven and gastric resection in three. Seven patients (32 percent) had postoperative complications and two (9 percent) died as a consequence of an associated septic process. An endoscopic follow up was done in nine patients and in two, the peptic ulcer remained active. These two patients were subjected to an elective excisional surgery. Conclusions: Local surgical correction of peptic ulcer perforation is the emergency treatment of choice but does not avoid ulcer relapse.
