: infection is associated with chronic gastritis, ulcers, and gastric cancer. The Type 4 secretion system (T4SS) translocates the CagA protein into host cells and plays an essential role in initiating gastric carcinogenesis. The CagL protein is a component of the T4SS. CagL amino acid polymorphisms are correlated with clinical outcomes. We aimed to study the association between CagL amino acid polymorphisms and peptic ulcer disease (PUD) and non-ulcer dyspepsia (NUD). : A total of 99 patients (PUD, 46; NUD, 53) were enrolled and screened for by qPCR from antrum biopsy samples. The amino acid polymorphisms of CagL were analyzed using DNA sequencing, followed by the MAFFT sequence alignment program to match the amino acid sequences. : Antrum biopsy samples from 70 out of 99 (70.7%) patients were found to be DNA-positive. A positive band for was detected in 42 out of 70 samples (PUD, 23; NUD, 19), and following this, these 42 samples were sequenced. In total, 27 different polymorphisms were determined. We determined three CagL amino acid polymorphism combinations, which were determined to be associated with PUD and NUD. Pattern 1 (K35/N122/V134/T175/R194/E210) was only detected in PUD patient samples and was related to a 1.35-fold risk ( = 0.02). Patterns 2 (V41/I134) and 3 (V41/K122/A171/I174) were found only in NUD patient samples and were linked to a 1.26-fold increased risk ( = 0.03). : We observed three new patterns associated with PUD and NUD. Pattern 1 is related to PUD, and the other two patterns (Patterns 2 and 3) are related to NUD. The patterns that we identified include the remote polymorphisms of the CagL protein, which is a new approach. These patterns may help to understand the course of infection.

OBJECTIVE
Peptic ulcer disease (PUD) in children is an uncommon disorder. An estimated 1.3 percent to 20 percent of people die from perforated peptic ulcers (PPU), a PUD consequence. Using a database, we assess the prevalence and prognosis of PPU in patients. We also do radiological and laparoscopic operations for PPU in young patients. In pediatric patients, sufficient accumulation of knowledge about laparoscopic repair is at the level of case reports. This study aims to assess the results in pediatric cases operated for PUP by open or laparoscopic surgery and determine the role of computed tomography (CT) in diagnosing PUP.
METHODS
Data was collected from the Department of Pediatric Surgery, Sisli Hamidiye Etfal Training and Research Hospital, Turkey, from 2015 to 2020. Patients under 18 years of age who were operated on for PUP between 2015 and 2020 were divided into two groups. Group 1 involved those patients operated by laparoscopic surgery, whereas Group 2 involved those used by open surgery. Both groups were retrospectively evaluated in terms of demographic data, clinical findings, preoperative-intraoperative findings and surgical methods (open or laparoscopic), duration of surgery, duration of nasogastric intubation, time of return to oral feeding, length of hospital stay, and postoperative complications.
RESULTS
18 patients consisting of 15 boys and 3 girls were included in the study. Group 1 involved 10 patients, whereas Group 2 involved 8 patients. In Group 1, the symptom onset period was 1.6 ± 1.9 days, and in Group 2, it was 6.6 ± 6.1 days. In the erect abdominal radiographs (AXR) of 10 (58.8%) patients, the air was under the diaphragm. Six patients whose erect AXRs showed no attitude under the diaphragm but had abdominal pain and acute abdominal manifestation were given abdominal computed tomography (CT) scanning. In all patients with PUP, laparoscopic/open surgery involves primary suturing and repair by omentoplasty (Graham patch). The mean operative time was 87.0 ± 26.3 minutes in Group 1 and 122.5 ± 57.6 minutes in Group 2. The mean length of hospital stay was 3.9 ± 1.3 days in Group 1 and 5.8 ± 2.1 days in Group 2. Neither group developed any major surgical complications.
CONCLUSIONS
Adolescents with a history of sudden onset and severe abdominal pain may present with peptic ulcer perforation even if there is no known diagnosis of peptic ulcer or predisposing factor. In cases suspected of PUP, it is vital to order and carefully examine erect AXR, which is an easy and inexpensive method. Computed tomography should be the first choice in patients without free air in ADBG but whose anamnesis and findings match peptic ulcer perforation.

Review
Helicobacter pylori infection is a major cause of peptic ulcer and is also associated with chronic gastritis, mucosa-associated lymphoid tissue (MALT) lymphoma, and adenocarcinoma of the stomach. Guidelines have been developed in the United States and Europe (areas with low prevalence) for the diagnosis and management of this infection, including the recommendation to 'test and treat' those with dyspepsia. A group of international experts performed a targeted literature review and formulated an expert opinion for evidenced-based benefits and harms for screening and treatment of H. pylori in high-prevalence countries. They concluded that in Arctic countries where H. pylori prevalence exceeds 60%, treatment of persons with H. pylori infection should be limited only to instances where there is strong evidence of direct benefit in reduction of morbidity and mortality, associated peptic ulcer disease and MALT lymphoma and that the test-and-treat strategy may not be beneficial for those with dyspepsia.

BACKGROUND
Many studies have been done in the literature on perforations due to substance abuse, and there are limited publications on perforations related to inhaled methamphetamine. Recently, in our clinic, we observed an increase in the number of patients with perforated peptic ulcer, which we think is secondary to a significant increase in the consumption of this drug. The main purpose of this study is to determine whether the use of inhaled methamphetamine known as 'fire and ice' is a factor directly related to peptic perforation and its complications and also to determine the demographic variables of patients with peptic ulcer perforation due to this substance use, in the context of the literature.
METHODS
A retrospective study was conducted by examining the medical records of 29 gastric perforation patients who underwent surgical treatment in our clinic in 2021. Data were transferred to SPSS.23 (IBM Inc., Chicago, IL, USA) program and evaluated with statistical analysis. Normality assumptions of continuous variables were examined with Kolmogorov-Smirnov test, and variance homogeneity was examined with Levene's test. Bi-level comparisons, t-test if the data are normally distributed and Mann-Whitney U-test for bi-level comparisons where the data are not normally distributed were used. Relationships between categorical variables were examined by Chi-square test analysis. P<0.05 was accepted as the level of significance in all analyzes.
RESULTS
Twenty-nine patients were divided into two groups as methamphetamine users (n=13) and non-users (n=16). There was a statistically significant difference according to the lower age in the group using methamphetamine (31.69-48.8-P=0.025). The pres-ence of PU history differed significantly between the groups (P=0.009). Interestingly, aspartate transaminase alanine aminotransferase values were lower in substance dependents (P=0.020). Furthermore, there was a significant difference in localization between groups (P<0.001). There was no statistically significant difference between the two groups in terms of gender, clinical presentation, and other laboratory values.
CONCLUSION
Methamphetamine consumption, known as fire and ice, is an important risk factor for ulcer development and subsequent perforation, especially in young patients and long-term consumption of this narcotic substance. It has been determined that this risk factor, which is currently considered rare, has been seen in a very large number in a short time in our clinic. The use of this substance, which is considered a major social threat, is becoming more and more widespread, and this study is only a small part of the iceberg reflected in the general surgery clinic of a hospital.

Review
Nonsteroidal anti-inflammatory drugs (NSAID) are some of the most commonly prescribed medications in clinical practice. The long-term use of NSAIDs is one of the main causes of peptic ulcers and the increased risk of upper gastrointestinal tract complications, such as perforation and bleeding. Thus, the prevention of NSAID-induced peptic ulcers is an important clinical issue. Previous studies have evaluated various strategies for preventing ulcers in patients requiring prolonged NSAID use. The Korean clinical practice guidelines have been published recently based on the evidence of the currently available data. This review describes the strategies for the prevention of peptic ulcers due to NSAID. An assessment of the risk factors for peptic ulcers from NSAID is recommended to identify patients who should be considered for primary prophylaxis. The risk of NSAID-induced peptic ulcers can be reduced by the concomitant use of proton pump inhibitors (PPI), misoprostol, and histamine-2 receptor antagonists. Selective cyclooxygenase-2 inhibitors can be used with caution due to concerns regarding cardiovascular toxicity. Attempts should be made to use the lowest dose and shortest duration of the NSAID.

BACKGROUND AND OBJECTIVES
Peptic ulcer disease is a common digestive system disease. However, whether peptic ulcer disease and obesity are related is unclear. We assessed the associations of obesity and metabolic status with peptic ulcer disease.
METHODS AND STUDY DESIGN
We conducted a cross-sectional study of 3561 individuals from the Wuwei cohort. We evaluated the associations of general and abdominal adiposity, as defined by different anthropometric indices, with peptic ulcer disease. Odds ratios and 95% confidence intervals were determined through binary logistic regression.
RESULTS
The odds ratio for peptic ulcer disease was 2.37 (1.46-3.84) for women with obesity, compared with the normal group. The association remained significant in Models 2 and 3, with odds ratios of 2.23 (1.35-3.69) and 2.03 (1.19-3.49), respectively. In Model 1, women with obesity had an odds ratio for duodenal ulcer of 2.76 (1.41-5.42) compared with the control group; this result remained significant in Models 2 and 3, with odds ratios of 2.52 (1.24-5.13) and 2.44 (1.13-5.28), respectively. In Model 1, women with metabolically healthy and unhealthy obesity had odds ratios for peptic ulcer disease of 2.26 (1.19-4.28) and 2.15 (1.12-4.15), respectively, compared with the control group. After adjustments for major covariates and H. pylori status, these respective odds ratios became 2.27 (1.20-4.30) and 2.17 (1.12-4.20) in Model 2 and 2.2 (1.15-4.20) and 2.16 (1.11-4.19) in Model 3.
CONCLUSIONS
General adiposity defined by body mass index is associated with peptic ulcer disease in women.

Review
Eradication of Helicobacter pylori causes improvement of gastric atrophy and intestinal metaplasia. Gastric acid secretion levels in corpus predominant gastritis increase after eradication. These changes can increase the risk of reflux esophagitis and low-dosage aspirin ulcers. Although eradication may reduce the overall risk of gastric cancer, a certain degree of risk remains, related to the extent of atrophy and intestinal metaplasia. Many post-eradication gastric cancers are the early depressed type, with low levels of epithelial atypia, and therefore can be difficult to distinguish endoscopically from benign erosion. Further research is required in this area.

OBJECTIVE
This study aims to evaluate the value of multidetector computed tomography (MDCT) in detecting the location of gastroduodenal perforation.
PATIENTS AND METHODS
This cross-sectional descriptive study was conducted with 47 patients who underwent contrast-enhancing MDCT and were diagnosed with gastroduodenal perforation during surgery between July 2021 and June 2022. Radiologic findings included pneumoperitoneum (distribution and quantity) and analyzed the image findings for localizing the site of gastroduodenal perforation.
RESULTS
Pneumoperitoneum was the most common finding [95.74% (45 out of 47 patients)]. Regarding air distribution, the sensitivity (Se) and negative predictive value (NPV) of abdominal free air and supramesocolic free air were the highest (100% for both). The accuracy (Acc) of supramesocolic free air was the highest (93.6%), followed by abdominal free air (89.4%). Subphrenic free air also had a high Acc value (89.4%), with Se, specificity (Sp), and positive predictive value (PPV) being 90%, 85,7%, and 97.3%, respectively. The Sp PPV of falciform ligament/ligamentum teres sign, and periportal free air were also high (100% for both). In contrast, retroperitoneal free air was valuable in determining retroperitoneal duodenal perforation with an Sp, Se of 100%, and Acc of 89.4%. The thickness of abdominal free air was ≥5.5 mm, suggesting gastroduodenal perforation with a Se, Sp, PPV, NPV, and Acc of 82.5%, 100%, 100%, 50%, and 85.1%, respectively.
CONCLUSIONS
Subphrenic free air, periportal free air, falciform ligament sign, and the air above transverse mesocolon were correlated to gastric and duodenal bulb perforation. Retroperitoneal air indicates the perforation at the retroperitoneal duodenum. The thickness of abdominal free air ≥5.5 mm indicates gastric and duodenal bulb perforation.

Review
The Korean guidelines for the Clinical Guidelines for Drug-related Peptic Ulcer were revised under the Korean College of Helicobacter and Upper Gastrointestinal Research in 2020. In these revised guidelines, treatment for infections is recommended in patients with a history of peptic ulcers and are receiving long-term low-dose aspirin therapy to prevent peptic ulcers and complications. The maintenance of anti-ulcer drugs, such as proton pump inhibitors, is also recommended after eradication if patients require other antiplatelet agents or anticoagulants. Regardless of eradication, when patients with a history of peptic ulcer take long-term low dose aspirin, the concomitant use of a proton pump inhibitor according to the severity of the peptic ulcer is recommended.

Review
Ulcer disease in excluded segments after Roux-Y gastric bypass (RYGB) is rare but can evolve into a life-threatening situation. The excluded segments exhibit a different behavior from that of non-altered anatomy; perforated ulcers do not result in pneumoperitoneum or free fluid, and therefore must be met with a low threshold for surgical exploration. The anatomical changes after RYGB impede routine access to the remnant stomach and duodenum. There are various options to address bleeding or perforated ulcers. While oversewing and drainage preserves the anatomy and forgoes resection, remnant gastrectomy offers a definitive solution. The importance of traditional risk factors such as smoking or use of non-steroidal anti-inflammatory drugs is unclear. Eradication of Helicobacter pylori and secondary prophylaxis with proton-pump inhibitors is advisable, albeit in double-dose.
