The epidemic of morbid obesity in the United States has reached dramatic proportions. Because of the associated comorbidities and because life style changes and exercise have limited effect, bariatric surgery has been used more often during the last 10 years as it has been shown to be safe and effective in decreasing weight and resolving comorbidities. Recently many studies have focused on a potential complication of bariatric surgery, gastroesophageal reflux disease, mostly because of the increasing use of sleeve gastrectomy. This article reviews the pathophysiology of reflux in morbid obese patients, the proper work-up before a bariatric operation, and the selection of the procedure based on the individual patient's characteristics.
Background and Aims: Colorectal cancer is the third most common cancer among both men and women in the United States. We aimed to determine racial and socioeconomic disparities in emergent colectomy rates for colorectal cancer in the US Health Care system. Material and Methods: We performed a retrospective analysis of the National Inpatient Sample including adult patients (⩾18 years) diagnosed with colorectal cancer, and who underwent colorectal resection while admitted between 2008 and 2015. Multivariable logistic and linear regression were used to assess the association between emergent admissions, compared to elective admissions, and postoperative outcomes. Results: A total of 141,641 hospitalizations were included: 93,775 (66%) were elective admissions and 47,866 (34%) were emergent admissions. Black patients were more likely to undergo emergent colectomy, compared to white patients (42% vs 32%, p < 0.0001). Medicaid and Medicare patients were also more likely to have an emergent colectomy, compared to private insurance (47% and 36% vs 25%, respectively, p < 0.0001), as were patients with low household income, compared to highest (38% vs 31%, p < 0.0001). Emergent procedures were less likely to be laparoscopic (19% vs 38%, p < 0.0001). Patients undergoing emergent colectomy were significantly more likely to have postoperative venous thromboembolism, wound complications, infection, bleeding, cardiac failure, renal failure, respiratory failure, shock, and inpatient mortality. Conclusion: There are significant racial and socioeconomic disparities in emergent colectomy rates for colorectal cancer. Efforts to reduce this disparity in colorectal cancer surgery patients should be prioritized to improve outcomes.
Gastroesophageal reflux disease (GERD) clinical presentation may encompass a myriad of symptoms that may mimic other esophageal and extra-esophageal diseases. Thus, GERD diagnosis by symptoms only may be inaccurate. Upper digestive endoscopy and barium esophagram may also be misleading. pH monitoring must be added often for a definitive diagnosis. The DeMeester score (DMS) is a composite score of the acid exposure during a prolonged ambulatory pH monitoring that has been used since 1970s to categorize patients as GERD+ or GERD-. We showed in this review that DMS has some limitations and strengths. Although there is not a single instrument to precisely diagnose GERD in all of its variances, pH monitoring analyzed at the light of DMS is still a reliable method for scientific purposes as well as for clinical decision making. There are no data that show that acid exposure time is superior-or for that matter inferior-as compared to DMS.
