RESUMEN
BACKGROUND: Emergency departments handle a large proportion of acute patients. In 2007, it was recommended centralizing the Danish healthcare system and establishing emergency departments as the main common entrance for emergency patients. Since this reorganization, few studies describing the emergency patient population in this new setting have been carried out and none describing diagnoses and mortality. Hence, we aimed to investigate diagnoses and 1- and 30-day mortality of patients in the emergency departments in the North Denmark Region during 2014-2016. METHODS: Population-based historic cohort study in the North Denmark Region (580,000 inhabitants) of patients with contact to emergency departments during 2014-2016. The study included patients who were referred by general practitioners (daytime and out-of-hours), by emergency medical services or who were self-referred. Primary diagnoses (ICD-10) were retrieved from the regional Patient Administrative System. For non-specific diagnoses (ICD-10 chapter 'Symptoms and signs' and 'Other factors'), we searched the same hospital stay for a specific diagnosis and used this, if one was given. We performed descriptive analysis reporting distribution and frequency of diagnoses. Moreover, 1- and 30-day mortality rate estimates were performed using the Kaplan-Meier estimator. RESULTS: We included 290,590 patient contacts corresponding to 166 ED visits per 1000 inhabitants per year. The three most frequent ICD-10 chapters used were 'Injuries and poisoning' (38.3% n = 111,274), 'Symptoms and signs' (16.1% n = 46,852) and 'Other factors' (14.52% n = 42,195). Mortality at day 30 (95% confidence intervals) for these chapters were 0.86% (0.81-0.92), 3.95% (3.78-4.13) and 2.84% (2.69-3.00), respectively. The highest 30-day mortality were within chapters 'Neoplasms' (14.22% (12.07-16.72)), 'Endocrine diseases' (8.95% (8.21-9.75)) and 'Respiratory diseases' (8.44% (8.02-8.88)). CONCLUSIONS: Patients in contact with the emergency department receive a wide range of diagnoses within all chapters of ICD-10, and one third of the diagnoses given are non-specific. Within the non-specific chapters, we found a 30-day mortality, surpassing several of the more organ specific ICD-10 chapters. TRIAL REGISTRATION: Observational study - no trial registration was performed.

OBJECTIVES: To determine the influence of hiatal hernia size and the laparoscopic fundoplication technique on the rate of hernia recurrence. PATIENTS AND METHODS: The preoperative, operative, and postoperative observational data of 381 patients operated on at the Department of Surgery of Kaunas University of Medicine during the period of 1998-2004 for hiatal hernia complicated with gastroesophageal reflux were analyzed. The surgery technique (Nissen or Toupet operation) was chosen independently of the hernia size. The radiological investigation of the esophagus-stomach using barium contrast as well as esophagogastroduodenoscopy and biopsy was performed for all patients before the surgery. The subjective and objective assessment of the patients' health status was investigated before and no less than 12 months after surgery. If the disease symptoms remained or new ones (i.e. pain behind the sternum, dysphagia, etc.) occurred after surgery, the hernia recurrence was suspected. The radiological investigation of the esophagus-stomach using barium contrast, as well as esophagogastroduodenoscopy and biopsy were performed at the consultative outpatient clinic. The hernia recurrence was confirmed after performing these two investigations. When analyzing the results, the patients were divided into two groups: Group 1--patients with small hiatal hernia (grade 1 and 2 hernia according to radiological classification), Group 2--patients with large hiatal hernia (grade 3 and 4 hernia according to radiological classification). RESULTS: A total of 272 (71.4%) patients had small hiatal hernia, and 109 (28.6%) patients had large ones. Hernia recurrence was diagnosed in 7 (2.58%) patients in Group 1, while in Group 2, 11 (10.1%) patients had hernia recurrence (P<0.05). Laparoscopic Nissen fundoplication was performed in 287 (75.4%) patients, after which 14 (4.98%) patients had hernia recurrence, while Toupet fundoplication was performed in 94 (24.6%) patients, after which 4 (4.3%) patients had hernia recurrence (P>0.05). CONCLUSIONS: The recurrence rate of hiatal hernia after laparoscopic fundoplications is significantly higher in patients with large hernias (grade 3 and 4 according to radiological classification). The surgery technique (Nissen or Toupet fundoplication) was not a significant factor affecting the recurrence rate of hiatal hernia.
