Never to be missed again - an analysis of 55 consecutive cases of traumatic diaphragmatic hernia.

BACKGROUND: This report reviews our clinical experience with 55 cases of traumatic diaphragmatic hernia at a Brazilian university hospital. Traumatic diaphragmatic hernia is an uncommon injury and presents diagnostic and therapeutic challenges. Occasionally, it is missed in trauma patients and is usually associated with significant morbidity and mortality. This analysis aimed to improve the diagnostic outcomes of trauma patient care. METHODS: Retrospective design analysis of database records of trauma patients at HC-Unicamp were performed to investigate incidence, trauma mechanism, diagnosis, herniated organs, associated injuries, trauma score, morbidity and mortality. RESULTS: Fifty-five patients were analysed. Blunt trauma was two-fold more frequent than penetrating trauma and was associated with high-grade injury; motor vehicle collision was the most common mechanism. Left-sided hernia was four-fold more frequent than that on the right side, although critical injuries were more frequently associated with the right side. The stomach was the most herniated organ in both trauma mechanisms. Preoperative diagnosis was mostly performed using chest radiography (55%). Postoperative diagnosis was mostly performed via laparotomy rather than laparoscopy. Associated injuries were observed in 43 patients (78%) and the mortality rate was 20% for both the sides. CONCLUSION: Isolated injuries are rare, and the presence of associated injuries increases morbidity and mortality. Chest radiography in the trauma bay is useful as an initial examination, although it is not suitable for use as a definitive method. Despite the use of laparoscopy in a few cases, laparotomy is the most common approach.

Endoscopic recanalization following accidental ligation of the common hepatic duct. A new technique.

Bile duct injury is a known complication of cholecystectomy. While minor injuries can be treated endoscopically, successful endoscopic management of complete ligation of the common hepatic duct (CHD) has not been described. Our aim was to report a novel technique for endoscopic recanalization of accidently ligated CHD. We demonstrated a 75 year old woman presented with a small bile leak and complete ligation of the CHD after open cholecystectomy subjected to successful biliary endoscopic recanalization. Cholangiogram demonstrated resolution of the bile leak and minimal residual narrowing of the CHD. Endoscopic intervention following biliary needle puncture access may avoid surgery in patients with CHD ligation or complex stenosis.

A 20-year experience with portal and superior mesenteric venous injuries: has anything changed?

OBJECTIVES: To identify predictive factors causing mortality in patients with injuries to the portal (PV) and superior mesenteric veins (SMV). DESIGN: Retrospective analysis of prospectively collected data. MATERIALS AND METHODS: Adults admitted with blunt or penetrating PV and SMV injuries at an academic level I trauma center during a 20-year period. RESULTS: Of 26,387 major trauma victims admitted from 1987 through 2006, 26 sustained PV or SMV injuries (PV=15, SMV=11). Mechanism of injury was penetrating in 19 (73%) and 20 were in shock. Active hemorrhage occurred in 21. Most patients had associated injuries (2.9+/-1.8/patient). Mean Injury Severity Score (ISS) was 27.8+/-16.8. All PV injuries underwent suture repair and 27% of SMV injuries were ligated. Overall mortality was 46% (PV=47%, SMV=45%). Stab wounds had a lower mortality (31%) compared to gunshot wounds (67%) and blunt injuries (57%). Nonsurvivors had a higher ISS (35.8 vs. 20.9; p=0.02), more associated injuries (3.7 vs. 2.2; p=0.02), were older, and had active hemorrhage. Active hemorrhage (p=0.04) was independently related to death while shock on admission (odds ratio=6.1, p=0.61) trended toward higher mortality. CONCLUSION: Despite improvements in trauma care, mortality of PV and SMV injuries remains high. Shock, active hemorrhage, and associated injuries were predictive of increased mortality.

Prevalence of cocaine and derivatives in blood and urine samples of trauma patients and correlation with injury severity: a prospective observational study.

PURPOSE: The abuse of cocaine and its derivatives presents a likely risk factor for injury. Trauma incurred by cocaine and derivative abusers may be more severe than that incurred by non-users. OBJECTIVES: To ascertain the presence of cocaine and its derivatives in trauma patients and to correlate RTS (Revised Trauma Score) and ISS (Injury Severity Score) with the presence of cocaine and its derivatives in blood and urine samples. METHODS: All trauma victims treated in an emergency unit between November 11, 2012 and September 15, 2013 were included in the study. Blood and urine samples were collected on admission to hospital. RTS and ISS scores were then compared with the presence or absence of cocaine and its derivatives in the samples. The associations between RTS < 7.84 and ISS > 16 and the independent variables were evaluated by the gross odds ratio values, determined by univariate logistic regression. Multivariate analysis was performed using multivariate logistic regression. RESULTS: Of 453 patients (83.7% male) included in the study, 28.6% presented ISS > 16 and 33.6% presented RTS < 7.84. A total of 435 samples were collected, and 86 (19.8%) provided positive samples for cocaine, 48 (11%) for crack and 69 (15.9%) for cocaethylene. Compared to other patients, drug users showed a greater probability of RTS < 7.84 (2.18 times greater) and a greater probability of ISS > 16 (1.76 times greater). CONCLUSION: For the trauma patients included in our study, the use of cocaine and its derivatives was shown to be associated with more severe traumas, as demonstrated by their RTS and ISS scores.

Proceedings of resources for optimal care of acute care and emergency surgery consensus summit Donegal Ireland.

BACKGROUND: Opportunities to improve emergency surgery outcomes exist through guided better practice and reduced variability. Few attempts have been made to define optimal care in emergency surgery, and few clinically derived key performance indicators (KPIs) have been published. A summit was therefore convened to look at resources for optimal care of emergency surgery. The aim of the Donegal Summit was to set a platform in place to develop guidelines and KPIs in emergency surgery. METHODS: The project had multidisciplinary global involvement in producing consensus statements regarding emergency surgery care in key areas, and to assess feasibility of producing KPIs that could be used to monitor process and outcome of care in the future. RESULTS: Forty-four key opinion leaders in emergency surgery, across 7 disciplines from 17 countries, composed evidence-based position papers on 14 key areas of emergency surgery and 112 KPIs in 20 acute conditions or emergency systems. CONCLUSIONS: The summit was successful in achieving position papers and KPIs in emergency surgery. While position papers were limited by non-graded evidence and non-validated KPIs, the process set a foundation for the future advancement of emergency surgery.

2016 WSES guidelines on acute calculous cholecystitis.

Acute calculus cholecystitis is a very common disease with several area of uncertainty. The World Society of Emergency Surgery developed extensive guidelines in order to cover grey areas. The diagnostic criteria, the antimicrobial therapy, the evaluation of associated common bile duct stones, the identification of "high risk" patients, the surgical timing, the type of surgery, and the alternatives to surgery are discussed. Moreover the algorithm is proposed: as soon as diagnosis is made and after the evaluation of choledocholitiasis risk, laparoscopic cholecystectomy should be offered to all patients exception of those with high risk of morbidity or mortality. These Guidelines must be considered as an adjunctive tool for decision but they are not substitute of the clinical judgement for the individual patient.

Penetrating bladder trauma: a high risk factor for associated rectal injury.

Demographics and mechanisms were analyzed in prospectively maintained level one trauma center database 1990-2012. Among 2,693 trauma laparotomies, 113 (4.1%) presented bladder lesions; 51.3% with penetrating injuries (n = 58); 41.3% (n = 24) with rectal injuries, males corresponding to 95.8%, mean age 29.8 years; 79.1% with gunshot wounds and 20.9% with impalement; 91.6% arriving the emergence room awake (Glasgow 14-15), hemodynamically stable (average systolic blood pressure 119.5 mmHg); 95.8% with macroscopic hematuria; and 100% with penetrating stigmata. Physical exam was not sensitive for rectal injuries, showing only 25% positivity in patients. While 60% of intraperitoneal bladder injuries were surgically repaired, extraperitoneal ones were mainly repaired using Foley catheter alone (87.6%). Rectal injuries, intraperitoneal in 66.6% of the cases and AAST-OIS grade II in 45.8%, were treated with primary suture plus protective colostomy; 8.3% were sigmoid injuries, and 70.8% of all injuries had a minimum stool spillage. Mean injury severity score was 19; mean length of stay 10 days; 20% of complications with no death. Concomitant rectal injuries were not a determinant prognosis factor. Penetrating bladder injuries are highly associated with rectal injuries (41.3%). Heme-negative rectal examination should not preclude proctoscopy and eventually rectal surgical exploration (only 25% sensitivity).

Management of severe thoracic impalement trauma against two-wheeled horse carriage: a case report and literature review.

Thoracic injuries in general are of great importance due to their high incidence and high mortality. Thoracic impalement injuries are rare but severe due to the combination of cause, effect and result. This study's primary objective is to report the case of a young man who was impaled by a two-wheeled horse carriage shaft while crashing his motorcycle in a rural zone. An EMT-B ferry was called at the crash scene and a conscious patient was found, sustaining a severe impalement injury to the left hemithorax, suspended over the floor by the axial skeleton with the carriage shaft coming across his left chest. As a secondary objective, a literature review of thoracic impalement injuries is performed. Cases of thoracic impalement injury require unique and individualized care based on injury severity and affected organs. Reported protocols for managing impalement injuries are entirely anecdotal, with no uniformity on impaled patient's approach and management. In penetrating trauma, it is essential not to remove the impaled object, so that possible vascular lesions remain buffered by the object, avoiding major bleeding and exsanguination haemorrhage. Severed impaled thoracic patients should be transferred to a specialist centre for trauma care, as these lesions typically require complex multidisciplinary treatment. High-energy thoracic impalement injuries are rare and hold a high mortality rate, due to the complexity of trauma and associated injuries such as thoracic wall and lung lesions. Modern medicine still seems limited in cases of such seriousness, not always with satisfactory results.
