BACKGROUND
Peptic ulcer disease (PUD), once primary a surgical problem, is now medically managed in the majority of patients. The surgical treatment of PUD is now strictly reserved for life-threatening complications. Free perforation, refractory bleeding and gastric outlet obstruction, although rare in the age of medical management of PUD, are several of the indications for surgical intervention. The acute care surgeon caring for patients with PUD should be facile in techniques required for bleeding control, bypass of peptic strictures, and vagotomy with resection and reconstruction. This video procedures and techniques article demonstrates these infrequently encountered, but critical operations.
CONTENT VIDEO DESCRIPTION
A combination of anatomic representations and videos of step-by-step instructions on perfused cadavers will demonstrate the key steps in the following critical operations. Graham patch repair of perforated peptic ulcer is demonstrated in both open and laparoscopic fashion. The choice to perform open versus laparoscopic repair is based on individual surgeon comfort. Oversewing of a bleeding duodenal ulcer via duodenotomy and ligation of the gastroduodenal artery is infrequent in the age of advanced endoscopy and interventional radiology techniques, yet this once familiar procedure can be lifesaving. Repair of giant duodenal or gastric ulcers can present a challenging operative dilemma on how to best repair or exclude the defect. Vagotomy and antrectomy, perhaps the least common of all the aforementioned surgical interventions, may require more complex reconstruction than other techniques making it challenging for inexperienced surgeons. A brief demonstration on reconstruction options will be shown, and it includes Roux-en-Y gastrojejunostomy.
CONCLUSION
Surgical management of PUD is reserved today for life-threatening complications for which the acute care surgeon must be prepared. This presentation provides demonstration of key surgical principles in management of bleeding and free perforation, as well as gastric resection, vagotomy and reconstruction.

BACKGROUND
The polymorphisms in the region between 58 and 62 amino acids of the 194-amino acid CagL protein (CagL hypervariable motif) affect the binding affinity of CagL to integrin α5β1 (ITGA5B1) receptor in host epithelial cells and have an effect on the development of various gastrointestinal diseases. We aimed to evaluate the associations of gastroduodenal pathologies, with the polymorphisms of cagL gene of Helicobacter pylori (H. pylori) and also associations between vacA genotypes and cagL polymorphisms.
METHODS
A total of 19 gastric cancer, 16 duodenal ulcer, and 26 non-ulcer dyspepsia patients were included in this case-control study. All cases had H. pylori. A fragment of 651 bp from gene cagL (hp0539) and cagA, vacA genes was amplified by polymerase chain reaction. Purified polymerase chain reaction products were sequenced by Sanger sequencing, and nucleotide sequences were translated into amino acid sequences.
RESULTS
All of the H. pylori strains had cagL and cagA genes. In the 16 (84%) gastric cancer cases, the D58 amino acid polymorphism was significant than the 4 (15.4%) duodenal ulcer cases (P = .029), and the D58/K59 amino acid polymorphism was significant in 12 (63.1%) of the gastric cancer cases than 1 (3.85%) duodenal ulcer case (P = .008). D58/K59 and DKIGQ (n = 10; 52.63%) were the most common polymorphisms in the gastric cancer and were associated with the vacA genotype s1/m2, respectively (P = .022 and P = .008). The D58/K59 amino acid polymorphism was found to have a significant Odds Ratio (OR) value of 8.9 (P = .0017) in multivariate logistic regression analysis.
CONCLUSIONS
The risk of gastric cancer development is 8.9 times higher with D58/K59 polymorphism.

BACKGROUND AND AIMS
Over-the-scope clips (OTSCs) substantially improved the endoscopic armamentarium for the treatment of severe GI bleeding and can potentially overcome limitations of standard clips. Data indicate a superiority of OTSCs in hemostasis as first- and second-line therapy. However, the impact of the OTSC designs, in particular the traumatic (-t) or atraumatic (-a) type, in duodenal ulcer bleeding has not been analyzed so far.
METHODS
This was a retrospective analysis of a prospective collected database from 2009 to 2020 of 6 German endoscopic centers. All patients who underwent emergency endoscopy and were treated using an OTSC for duodenal ulcer bleeding were included. OTSC-t and OTSC-a patients were compared by the Fisher exact test, χ test, or Mann-Whitney U test as appropriate. A propensity score-based 1:1 matching was performed to obtain equal distribution of baseline characteristics in both groups.
RESULTS
The entire cohort comprised 173 patients (93 OTSC-a, 80 OTSC-t). Age, gender, anticoagulant therapy, Rockall score, and treatment regimen had similar distributions in the 2 groups. However, the OTSC-t group showed significantly more active bleeding ulcers (Forrest Ia/b). Matching identified 132 patients (66 in both groups) with comparable baseline characteristics. Initial bleeding hemostasis (OTSC-a, 90.9%; OTSC-t, 87.9%; P = .82) and 72-hour mortality (OTSC-a, 4.5%; OTSC-t, 6.0%; P > .99) were not significantly different, but the OTSC-t group revealed a clearly higher rate of recurrent bleeding (34.9% vs 7.6%, P < .001) and necessity of red blood cell transfusions (5.1 ± 3.4 vs 2.5 ± 2.4 concentrates, P < .001).
CONCLUSIONS
For OTSC use, the OTSC-a should be the preferred option for duodenal ulcer bleeding.

BACKGROUND
Laparoscopic single-port surgery has widely been introduced for the treatment of various abdominal conditions. But controversies still exist regarding its potential advantages and risks, especially for emergency surgery. The aim of this study was to evaluate the results of a single-port laparoscopic repair using straight laparoscopic instruments for the treatment of perforated duodenal ulcers.
METHODS
A prospective consecutive case series was conducted including all patients with a perforated duodenal ulcer who underwent a laparoscopic single-port repair at a single institution from January 2012 to June 2018. The operation was performed through a single port using conventional straight laparoscopic instruments and intra-corporeal knot tying techniques.
RESULTS
Out of 75 patients, simple closure of the perforation without omental patch was accomplished in 96% of cases. Conversion to an open operation was required in one patient (1.3%) due to a posterior duodenal perforation, and additional trocar placement was needed in another patient (1.3%). The mean incision length was 2.0 ± 0.2 cm. The mean operation time was 63.0 ± 26.6 min. Meantime a nasogastric tube remained in place was 2.9 ± 0.8 days. Mean duration of analgesic use was 2.8 ± 0.8 days. The rate of postoperative complications was 2.7%, including two patients with wound infections. There were no instances of intestinal leak or abscess. The postoperative hospital stay was 5.7 ± 1.2 days.
CONCLUSION
Laparoscopic single-port repair using conventional straight laparoscopic instruments with intra-corporeal knot tying technique was safe and feasible for patients with perforated duodenal ulcers with low risk factors. This method offers results comparable to those expected with the standard multiport laparoscopic approach with the addition of improved cosmetic outcomes.

Review
Specific risk factors for gastroduodenal surgery in cirrhotic patients have been identified, which dictates for a more personalized management. The retrospective study was conducted between 2012-2019 on twelve patients (7 cases of duodenal ulcer, 2 cases of gastric ulcer and 3 patients with gastric cancer). We took into account a number of possible factors involved in the unfavorable evolution of patients, based on data published in the literature so far. In order to follow the involvement of each factor we compared two groups of patients, one with unfavorable evolutions, exitus and another with favorable evolutions. Emergency surgery, the presence of ascites at the time of intervention, a higher than 30 MELD score, alcoholic cirrhosis, liver encephalopathy and liver failure are common factors that are found in a high percentage (between 75% and 100%) in patients who have had an unfavorable evolution, exitus. The same risk factors are found in much lower percentages in patients who have evolved favorably postoperatively, most between 12.5% and 25%. We analyzed preoperative aspects, surgical approach, complications and risk factors for these patients, compared them with the results of our study and identified future therapeutic possibilities. For CHILD B or C patients, the indication for surgery should be discussed in advance with a multidisciplinary team. Endoscopic submucosal dissection or discontinuation of D2 dissection should be considered in these patients.

BACKGROUND
A recent report has shown that the phylogenetic origin of Helicobacter pylori based on multi-locus sequence typing (MLST) was significantly associated with the severity of gastritis in Colombia. However, the potential relationship between phylogenetic origin and clinical outcomes was not examined in that study. If the phylogenetic origin rather than virulence factors were truly associated with clinical outcomes, identifying a population at high risk for gastric cancer in Colombia would be relatively straightforward. In this study, we examined the phylogenetic origins of strains from gastric cancer and duodenal ulcer patients living in Bogota, Colombia.
METHODS
We included 35 gastric cancer patients and 31 duodenal ulcer patients, which are considered the variant outcomes. The genotypes of cagA and vacA were determined by polymerase chain reaction. The genealogy of these Colombian strains was analyzed by MLST. Bacterial population structure was analyzed using STRUCTURE software.
RESULTS
H. pylori strains from gastric cancer and duodenal ulcer patients were scattered in the phylogenetic tree; thus, we did not detect any difference in phylogenetic distribution between gastric cancer and duodenal ulcer strains in the hpEurope group in Colombia. Sixty-six strains, with one exception, were classified as hpEurope irrespective of the cagA and vacA genotypes, and type of disease. STRUCTURE analysis revealed that Colombian hpEurope strains have a phylogenetic connection to Spanish strains.
CONCLUSIONS
Our study showed that a phylogeographic origin determined by MLST was insufficient for distinguishing between gastric cancer and duodenal ulcer risk among hpEurope strains in the Andean region in Colombia. Our analysis also suggests that hpEurope strains in Colombia were primarily introduced by Spanish immigrants.

Observational Study
INTRODUCTION
Obesity is a well-known risk factor for a variety of gastrointestinal disorders (GID). Helicobacter pylori is associated with different GID, such as gastric cancer and chronic gastritis. In this study, we investigated the prevalence of dominant genotypes in H. pylori isolated from obese patients diagnosed with gastric ulcer, duodenal ulcer, and gastric cancer.
METHODS
A total of 222 H. pylori-positive samples were collected from patients with obesity. GID and gastric cancer were identified by endoscopy and histopathology, respectively. Three biopsy specimens from the gastric antrum were obtained from each patient for culture tests, histological examination, and identification of vacuolating cytotoxin A (vacA) (vacA s1, vacA s2, vacA m1, vacA m2, vacA s1m1 vacA s1m2, vacA s2m1, and vacA s2m2), cagA, cagE, iceA1, oipA, dupA, and babA2 using polymerase chain reaction.
RESULTS
vacA, cagE, cagA, iceA1, oipA, dupA, and babA2 genes were detected in 222 (100%), 171 (77%), 161 (72.5%), 77 (34.6%), 77 (34.6%), 137 (61%), and 69 (31%) patients with obesity, respectively. Our findings revealed that vacA, iceA1, oipA, and babA2 were significantly associated with a higher risk of GID, while cagE, cagA, and dupA indicated no correlation with the development of GID. Also, in the combination of s- and m-region genotypes, s1m2 (79%) was the most frequently identified genotype in patients with obesity. A significant association was also found between cagA and the presence of vacA genotypes (except for vacA m1 and babA2).
CONCLUSIONS
This study indicated the high prevalence of different virulence genes in H. pylori isolated from obese patients and supported the significant role of H. pylori in the development of GID.

Meta-Analysis Review
BACKGROUND
Peptic ulcer disease is the cause of dyspepsia in about 10% of people. Ninety-five percent of duodenal and 70% of gastric ulcers are associated with Helicobacter pylori. Eradication of H. pylori reduces the relapse rate of ulcers but the magnitude of this effect is uncertain. This is an update of Ford AC, Delaney B, Forman D, Moayyedi P. Eradication therapy for peptic ulcer disease in Helicobacter pylori-positive patients. Cochrane Database of Systematic Reviews 2006, Issue 2. Art. No.: CD003840. DOI: 10.1002/14651858.CD003840.pub4.
OBJECTIVES
To assess the proportion of peptic ulcers healed and the proportion of participants who remained free from relapse with eradication therapy against placebo or other pharmacological therapies in H. pylori-positive people.To assess the proportion of participants that achieved complete relief of symptoms and improvement in quality of life scores.To compare the incidence of adverse effects/drop-outs (total number for each drug) associated with the different treatments.To assess the proportion of participants in whom successful eradication was achieved.
SEARCH METHODS
In this update, we identified trials by searching the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE (1950 to March 2016) and Ovid EMBASE (1980 to March 2016). To identify further relevant trials, we handsearched reference lists from trials selected by electronic searching, and published abstracts from conference proceedings from the United European Gastroenterology Week (published in Gut) and Digestive Disease Week (published in Gastroenterology). The search was last updated in March 2016. We contacted members of Cochrane Upper GI and Pancreatic Diseases, and experts in the field and asked them to provide details of outstanding clinical trials and any relevant unpublished materials.
SELECTION CRITERIA
We analysed randomised controlled trials of short- and long-term treatment of peptic ulcer disease in H. pylori-positive adults. Participants received at least one week of H. pylori eradication compared with ulcer healing drug, placebo or no treatment. Trials were included if they reported assessment from two weeks onwards.
DATA COLLECTION AND ANALYSIS
We collected data on ulcer healing, recurrence, relief of symptoms and adverse effects. We calculated the risk ratio (RR) with 95% confidence intervals (CI) using both fixed-effect and random-effects models with Review Manager software (RevMan 5.3) based on intention-to-treat analysis as far as possible.
MAIN RESULTS
A total of 55 trials were included for one or more outcomes for this review.In duodenal ulcer healing, eradication therapy was superior to ulcer healing drug (UHD) (34 trials, 3910 participants, RR of ulcer persisting = 0.66, 95% confidence interval (CI) 0.58 to 0.76; 381/2286 (adjusted proportion: 12.4%) in eradication therapy plus UHD versus 304/1624 (18.7%) in UHD; low quality evidence) and no treatment (two trials, 207 participants, RR 0.37, 95% CI 0.26 to 0.53; 30/125 (adjusted proportion: 21.7%) in eradication therapy versus 48/82 (58.5%) in no treatment; low quality evidence).In gastric ulcer healing, the differences were imprecise between eradication therapy and UHD (15 trials, 1974 participants, RR 1.23, 95% CI 0.90 to 1.68; 220/1192 (adjusted proportion: 16.0%) in eradication therapy plus UHD versus 102/782 (13.0%) in UHD; very low quality evidence). In preventing duodenal ulcer recurrence the differences were imprecise between maintenance therapy with H.pylori eradication therapy and maintenance therapy with UHD (four trials, 319 participants, RR of ulcer recurring 0.73; 95% CI 0.42 to 1.25; 19/159 (adjusted proportion: 11.9%) in eradication therapy versus 26/160 (16.3%) in UHD; very low quality evidence), but eradication therapy was superior to no treatment (27 trials 2509 participants, RR 0.20, 95% CI 0.15 to 0.26; 215/1501 (adjusted proportion: 12.9%) in eradication therapy versus 649/1008 (64.4%) in no treatment; very low quality evidence).In preventing gastric ulcer recurrence, eradication therapy was superior to no treatment (12 trials, 1476 participants, RR 0.31, 95% CI 0.22 to 0.45; 116/697 (adjusted proportion: 16.3%) in eradication therapy versus 356/679 (52.4%) in no treatment; very low quality evidence). None of the trials reported proportion of people with gastric ulcer not healed after initial therapy between H.pylori eradication therapy and no active treatment or the proportion of people with recurrent gastric ulcer or peptic ulcers during maintenance therapy between H.pylori eradication therapy and ulcer healing drug therapy.
AUTHORS' CONCLUSIONS
Adding a one to two-week course of H. pylori eradication therapy is an effective treatment for people with H. pylori-positive duodenal ulcer when compared to ulcer healing drugs alone and no treatment. H. pylori eradication therapy is also effective in preventing recurrence of duodenal and gastric ulcer compared to no treatment. There is currently no evidence that H. pylori eradication therapy is an effective treatment in people with gastric ulcer or that it is effective in preventing recurrence of duodenal ulcer compared to ulcer healing drug. However, confidence intervals were wide and significant benefits or harms of H. pylori eradication therapy in acute ulcer healing of gastric ulcers compared to no treatment, and in preventing recurrence of duodenal ulcers compared to ulcer healing drugs cannot be ruled out.

Review
() is a microaerophilic, Gram-negative, human gastric pathogen found usually in the mucous lining of stomach. It infects more than 50% of the world's population and leads to gastroduodenal diseases. The outcome of disease depends on mainly three factors: Host genetics, environment and bacterial factors. Among these, bacterial virulence factors such as , are well known for their role in disease outcomes. However, based on the global epidemiological results, none of the bacterial virulence (gene) factors was found to be associated with particular diseases like duodenal ulcer (DU) in all populations. Hence, substantial importance has been provided for research in strain-specific genes outside the pathogenicity island, especially genes located within the plasticity regions. found within the plasticity regions was first demonstrated in 2005 and was proposed for duodenal ulcer development and reduced risk of gastric cancer in certain geographical regions. Due to the discrepancies in report from different parts of the world in DU development related to virulence factor, became an interesting area of research in elucidating the role of this gene in the disease progression. In this review, we shed light on the detailed information available on the polymorphisms in and their clinical relevance. We have critically appraised several pertinent studies on and discussed their merits and shortcomings. This review also highlights gene as an important biomarker for DU in certain populations.
