BACKGROUND
Whether the positive associations of smoking and alcohol consumption with gastrointestinal diseases are causal is uncertain. We conducted this Mendelian randomization (MR) to comprehensively examine associations of smoking and alcohol consumption with common gastrointestinal diseases.
METHODS
Genetic variants associated with smoking initiation and alcohol consumption at the genome-wide significance level were selected as instrumental variables. Genetic associations with 24 gastrointestinal diseases were obtained from the UK Biobank, FinnGen study, and other large consortia. Univariable and multivariable MR analyses were conducted to estimate the overall and independent MR associations after mutual adjustment for genetic liability to smoking and alcohol consumption.
RESULTS
Genetic predisposition to smoking initiation was associated with increased risk of 20 of 24 gastrointestinal diseases, including 7 upper gastrointestinal diseases (gastroesophageal reflux, esophageal cancer, gastric ulcer, duodenal ulcer, acute gastritis, chronic gastritis, and gastric cancer), 4 lower gastrointestinal diseases (irritable bowel syndrome, diverticular disease, Crohn's disease, and ulcerative colitis), 8 hepatobiliary and pancreatic diseases (non-alcoholic fatty liver disease, alcoholic liver disease, cirrhosis, liver cancer, cholecystitis, cholelithiasis, and acute and chronic pancreatitis), and acute appendicitis. Fifteen out of 20 associations persisted after adjusting for genetically predicted alcohol consumption. Genetically predicted higher alcohol consumption was associated with increased risk of duodenal ulcer, alcoholic liver disease, cirrhosis, and chronic pancreatitis; however, the association for duodenal ulcer did not remain statistically significant after adjustment for genetic predisposition to smoking initiation.
CONCLUSIONS
This study provides MR evidence supporting causal associations of smoking with a broad range of gastrointestinal diseases, whereas alcohol consumption was associated with only a few gastrointestinal diseases.

Genetic factors are recognized to contribute to peptic ulcer disease (PUD) and other gastrointestinal diseases, such as gastro-oesophageal reflux disease (GORD), irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Here, genome-wide association study (GWAS) analyses based on 456,327 UK Biobank (UKB) individuals identify 8 independent and significant loci for PUD at, or near, genes MUC1, MUC6, FUT2, PSCA, ABO, CDX2, GAST and CCKBR. There are previously established roles in susceptibility to Helicobacter pylori infection, response to counteract infection-related damage, gastric acid secretion or gastrointestinal motility for these genes. Only two associations have been previously reported for duodenal ulcer, here replicated trans-ancestrally. The results highlight the role of host genetic susceptibility to infection. Post-GWAS analyses for PUD, GORD, IBS and IBD add insights into relationships between these gastrointestinal diseases and their relationships with depression, a commonly comorbid disorder.

Duodenal ulcer perforation, a frequent surgical emergency, needs simple closure with indirect Graham's Omentopexy which is effective with excellent results in majority of cases despite patients' late presentation. The objective of the study was to determine the frequency of postoperative complications of perforated duodenal ulcer, conducted in the Surgery Department, Jinnah Postgraduate Medical Centre, Karachi, from March 20, 2018 to September 20, 2018. The study was a descriptive case series of 108 patients of both genders with perforated duodenal ulcer > 1 week old with ASA score I & II. Patients with trauma and comorbidities were excluded. The patients underwent laparotomy and peritoneal toilet, and after noting the site of perforation indirect Graham's Omentopexy was performed. Complications like duodenal fistula, peritonitis, and paralytic ileus, and patient's death within 10 days of surgery were noted. Age ranged from 18 to 50 years with mean age of 35.027±5.13 years, mean weight 71.120±12.77 kg, mean height 1.541 ±0.09 metres, mean BMI 29.975±4.99 kg/m2, and the mean duration of complaint was 4.194±1.30 weeks. Male predominance in 75 (69.4%) patients. Duodenal fistula was seen in 10 (9.3%) patients, peritonitis 12 (11.1%), paralytic ileus 14 (13%) and mortality was in 11 (10.2%) patients.

Meta-Analysis Review
BACKGROUND
Pharmacologic stress ulcer prophylaxis (SUP) is recommended in critically ill patients with high risk of stress-related gastrointestinal (GI) bleeding. However, as to patients receiving enteral feeding, the preventive effect of SUP is not well-known. Therefore, we performed a meta-analysis of randomized controlled trials (RCTs) to evaluate the effect of pharmacologic SUP in enterally fed patients on stress-related GI bleeding and other clinical outcomes.
METHODS
We searched PubMed, Embase, and the Cochrane database from inception through 30 Sep 2017. Eligible trials were RCTs comparing pharmacologic SUP to either placebo or no prophylaxis in enterally fed patients in the ICU. Results were expressed as risk ratio (RR) and mean difference (MD) with accompanying 95% confidence interval (CI). Heterogeneity, subgroup analysis, sensitivity analysis and publication bias were explored.
RESULTS
Seven studies (n = 889 patients) were included. There was no statistically significant difference in GI bleeding (RR 0.80; 95% CI, 0.49 to 1.31, p = 0.37) between groups. This finding was confirmed by further subgroup analyses and sensitivity analysis. In addition, SUP had no effect on overall mortality (RR 1.21; 95% CI, 0.94 to 1.56, p = 0.14), Clostridium difficile infection (RR 0.89; 95% CI, 0.25 to 3.19, p = 0.86), length of stay in the ICU (MD 0.04 days; 95% CI, -0.79 to 0.87, p = 0.92), duration of mechanical ventilation (MD -0.38 days; 95% CI, -1.48 to 0.72, p = 0.50), but was associated with an increased risk of hospital-acquired pneumonia (RR 1.53; 95% CI, 1.04 to 2.27; p = 0.03).
CONCLUSIONS
Our results suggested that in patients receiving enteral feeding, pharmacologic SUP is not beneficial and combined interventions may even increase the risk of nosocomial pneumonia.

Marginal ulcers are a late complication of gastric bypass surgery. A marginal ulcer is a term for ulcers that develop at the margins of a gastrojejunostomy, primarily on the jejunal side. A perforated ulcer involves the entire thickness of an organ, creating an opening on both surfaces. We will present an intriguing case of a 59-year-old Caucasian female who arrived at the emergency department with diffused chest and abdominal pain that began in her left shoulder and went down to the right lower quadrant area. The patient was in visible pain with restlessness, and her abdomen was moderately distended. The computed tomography (CT) showed possible perforation in the gastric bypass surgery area, but the results were inconclusive. The patient had laparoscopic cholecystectomy ten days prior, and the pain began right after surgery. The patient underwent an open abdominal exploratory surgery, with the closure of the perforated marginal ulcer. The fact that the patient had undergone another surgery and had pain immediately afterward also obscured the diagnosis. This case shows the rare presentation of the patientäs diverse signs and symptoms and inconclusive reports that led to the open abdominal exploratory surgery that finally confirmed the diagnosis. This case highlights the importance of a thorough past medical history, including surgical history. The past surgical history led the team to zone in on the gastric bypass area, leading to an accurate differential diagnosis.

We describe a rare case of a 60-year-old man with known history of peptic ulcer disease who presented with melena and epigastric pain secondary to coil migration into duodenal mucosa 4 years after the initial therapeutic embolisation of the gastroduodenal artery. Upper endoscopy revealed oozing duodenal ulcer at the same site of the previously located duodenal ulcer 4 years ago and metal coil impacted at the duodenal mucosa. It is unclear if the coil migration is the effect or the cause of the bleeding duodenal ulcer. Our patient was treated by surgical intervention due to failed endoscopic haemostasis and medical management.
