RESUMEN
Hiatus hernia (HH) is a prevalent endoscopic finding in clinical practice, frequently co-occurring with esophageal disorders, yet the prevalence and degree of association remain uncertain. We aim to investigate HH's frequency and its suspected association with esophageal disorders. We reviewed endoscopic reports of over 75,000 consecutive patients who underwent gastroscopy over 12 years in two referral centers. HH was endoscopically diagnosed. We derived data on clinical presentation and a comprehensive assessment of benign and malignant esophageal pathologies. We performed multiple regression models to identify esophageal sequela associated with HH. The overall frequency of HH was (16.8%); the majority (89.5%) had small HHs (<3 cm). Female predominance was documented in HH patients, who were significantly older than controls (61.1±16.5 vs. 52.7±20.0; P < 0.001). The outcome analysis of esophageal pathology revealed an independent association between HH, regardless of its size, and erosive reflux esophagitis (25.7% vs. 6.2%; OR = 3.8; P < 0.001) and Barrett's esophagus (3.8% vs. 0.7%; OR = 4.7, P < 0.001). Furthermore, following rigorous age and sex matching, in conjunction with additional multivariable analyses, large HHs were associated with higher rates of benign esophageal strictures (3.6% vs. 0.3%; P < 0.001), Mallory Weiss syndrome (3.6% vs. 2.1%; P = 0.01), and incidents of food impactions (0.9% vs. 0.2%; P = 0.014). In contrast, a lower rate of achalasia was noted among this cohort (0.55% vs. 0%; P = 0.046). Besides reflux-related esophageal disorders, we outlined an association with multiple benign esophageal disorders, particularly in patients with large HHs.

Background: Chronic constipation, a prevalent gastrointestinal complaint, exhibits rising incidence and diverse clinical implications, especially among the aging population. This study aims to assess colonoscopy performance in chronic constipation across age groups, comprehensively evaluating diagnostic yield and comparing results with average-risk controls. Methods: A retrospective analysis was conducted on 50,578 colonoscopy procedures performed over 12 years, including 5478 constipated patients. An average-risk control group (n = 4100) was included. Data extracted from electronic medical records covered demographics, operational aspects, and colonoscopy findings. The primary outcome measures included the diagnosis rate of colorectal cancer (CRC), polyp detection rate (PDR), and inflammatory bowel disease (IBD) diagnoses in constipated patients versus controls, with age-based and multivariate analyses. Results: Constipated patients exhibiting lower rates of adequate bowel preparation (92.7% vs. 85.3%; p < 0.001) and a lower cecal intubation rate. No significant variances between CRC and PDR were observed between constipated and controls, except for a potential of a slightly elevated CRC risk in constipated patients older than 80 (2.50% vs. 0% in controls; p = 0.07). Multivariate analysis demonstrated, across all age groups, that constipation did not confer an increased risk for CRC or polyp detection. Younger constipated patients exhibited a higher rate of IBD diagnoses (1.7% vs. 0.1% in controls; p < 0.001). Conclusions: Constipation did not confer an increased risk for CRC or polyps, among any age groups, except for a potential signal of elevated CRC risk in patients older than 80; additionally, it was associated with higher rates of IBD in younger patients.
RESUMEN
Background: Although abdominal pain is one of the most common complaints of patients presenting to the emergency department (ED), and acute appendicitis is a leading surgical differential diagnosis of patients presenting with abdominal pain, the diagnosis of acute appendicitis remains challenging. We examined the missed diagnosis rate of acute appendicitis in one ED and evaluated the association between disposition (discharge home or hospitalization in the wrong department) and complicated appendicitis. Methods: We retrospectively evaluated the medical records of patients with acute appendicitis and periappendicular abscess from January 1, 2013, to December 31, 2016. Results: The diagnosis of acute appendicitis was missed in 7.1% of patients (90/1,268) at their first ED encounter: 44 were discharged, and 47 were hospitalized with a wrong diagnosis (1 female patient was both discharged and then hospitalized with an incorrect diagnosis). Compared to the patients who were correctly diagnosed, patients with a missed diagnosis were older (median age 29 years vs 23 years, P=0.022), their time between ED first encounter and surgery was longer (median 29.5 hours vs 9.3 hours, P<0.001), and their rate of complicated appendicitis was higher (54.4% vs 27.5%, P<0.001). Missed females were more commonly hospitalized (26/39), while missed males were more commonly discharged from the ED (31/52) (P=0.019). No differences in the time between the first ED encounter and surgery (29.6 hours vs 29.6 hours, P=0.29) and the rate of complicated appendicitis (63.8% vs 43.2%, P=0.06) were noted between hospitalized patients with a wrong diagnosis and those discharged from the ED. Of the 25 patients with periappendicular abscesses, only 3 could be related to missed diagnoses during their first encounter in the ED. Conclusion: We found that 7.1% of patients were missed during their first encounter in the ED. Hospitalization in departments other than general surgery was not protective against delay in surgery or the development of complicated appendicitis. Periappendicular abscess was attributable to late referral rather than a missed diagnosis in most patients.
