Objective: To evaluate the pattern and outcome of blunt abdominal trauma using haemodynamic stability and ultrasonography in the selection of patients for nonoperative management in a facility without computed tomogram. Methods: Patients admitted with blunt abdominal trauma between February 2005 and January 2010 were prospectively studied. Haemodynamic stability and sonography formed the basis for selecting patients for nonoperative management. Results: In total, 58 patients suffered blunt abdominal trauma and 19(33%) patients were successfully managed nonoperatively suffered blunt solid abdominal organ injuries. Road traffic accidents inflicted 17(89%) patients while 2(11%) patients sustained sports injury (football). The spleen was the commonest solid organ injured 12(60%), while the liver and kidney were injured in 6(30%) and 2(10%) respectively. Associated injuries were fractured left femur recorded in 3(16%) patients and fractured rib in a patient (5%). Conclusion: Nonoperative treatment is a safe and effective method in the management of haemodynamically stable patient with blunt solid abdominal organ injury. This translated to a reduction in hospital stay, absence of the risk of blood transfusion as well as attendant morbidity and mortality associated with laparotomy. Establishment of trauma system, provision of diagnostic and monitoring facilities, good roads, and education on road safety is recommended for improved outcome.展开更多

They are the first cause of small bowel obstruction. Diagnosis is based on clinical evaluation, water-soluble contrast followthrough and computed tomography scan. For patients presenting no signs of strangulation, peritonitis or severe intestinal impairment there is good evidence to support non-operative management. Open surgery is the preferred method for the surgical treatment of adhesive small bowel obstruction, in case of suspected strangulation or after failed conservative management, but laparoscopy is gaining widespread acceptance especially in selected group of patients. "Good" surgical technique and anti-adhesive barriers are the main current concepts of adhesion prevention. We discuss current knowledge in modern diagnosis and evolving strategies for management and prevention that are leading to stratified care for patients.展开更多

Objectives: To study the pattern of splenic injuries of the patient, management instituted and its outcome at Khartoum. Patients and Methods: This is a prospective, analytic and hospital-based multicenteric study, conducted at the three main Teaching hospitals at Khartoum. The study was carried over a period from April 2012 to February 2013. It includes all patients, diagnosed as traumatic splenic injury. Excluded were patients with history of splenic disease, iatrogenic injury or spontaneous rupture. Results: The study included 47 patients: their mean age was 26.4 years (SD ± 14.5). Most of them 41 (87.2%) were in the first four decades of life. Males were predominant 41 (87.2%), with a male to female ratio of 6.8:1. The majority of our patients had blunt abdominal trauma 39 (83%), of whom, road traffic accident accounted for 51.1% and none reported cases of gunshot. Isolated splenic injury was found in 23 (48.9%), and Haemodynamic stability was seen in 27 (57.4%) on presentation. The initial haemoglobin assessment revealed <9 gram/dl in 53.2%. CT scan was performed to 24 (51.1%), of whom 66 patients were Grade I and II and none of our patients were diagnosed as Grade V. Blood transfusion was required in 42 (89.4%). Operative treatment was adopted in 66% (61.7% total splenectomy and 4.3% splenorrhaphy), while selective non-operative management was successful in 16 (34%) of the patients. Higher intra-operative grade of splenic injury was found to be significantly associated with blunt abdominal trauma, haemodynamic instability and associated intra-abdominal injuries. 44 patients (93.6%) were discharged home in a general good condition. The morbidity and mortality were seen in 8.5% and 6.4% respectively. Conclusion: Splenic injuries usually follow blunt abdominal trauma, particularly after road traffic accidents. It is common during the first four decades of life with males being frequently affected. The great success rate of adopting selective non-operative management is worthwhile.展开更多

The patient with hemodynamic stability and absence of peritonitis should be managed non-operatively. NOM has an overall success rate of 80%—90%. It also can reduce the rate of non-therapeutic abdominal exploration, preserve organ function, and has been defined as the safest choice in experienced centers. However, NOM carries a risk of missed injury such as hollow organ injury, diaphragm injury, and delayed hemorrhage. Adjunct therapies such as angiography with embolization, endoscopic retrograde cholangiopancreatography with stenting, and percutaneous drainage could increase the chances of successful NOM. This article aims to describe the evolution of NOM and define its place in specific abdominal solid organ injury for the practitioner who faces this problem.展开更多
