Routine repeat head CT for minimal head injury is unnecessary

BACKGROUND: Patients with MHI and a positive head computed tomography (CT) scan frequently have a routine repeat head CT (RRHCT) to identify possible evolution of the head injury requiring intervention. RRHCT is ordered based on the premise that significant injury progression may take place in the absence of clinical deterioration. METHODS: In a Level I urban trauma center with a policy of RRHCT, we reviewed the records of 692 consecutive trauma patients with Glasgow Coma Scale scores of 13-15 and a head CT (October 2004 through October 2005). The need for medical or surgical neurologic intervention after RRHCT was recorded. Patients with a worse and unchanged RRHCT were compared, and independent predictors of a worse RRHCT were identified by stepwise logistic regression. RESULTS: There were 179 patients with MHI and RRHCT ordered. Of them, 37 (21%) showed signs of injury evolution on RRHCT and 7 (4%) required intervention. All 7 had clinical deterioration preceding RRHCT. In no patient without clinical deterioration did RRHCT prompt a change in management. A Glasgow Coma Scale score less than 15 (13 or 14), age higher than 65 years, multiple traumatic lesions found on first head CT, and interval shorter than 90 minutes from arrival to first head CT predicted independently a worse RRHCT. CONCLUSIONS: RRHCT is unnecessary in patients with MHI. Clinical examination identifies accurately the few who will show significant evolution and require intervention.     

Routine postoperative upper gastroesophageal imaging is unnecessary after laparoscopic Roux-en-Y gastric bypass

Routine early postoperative upper gastroesophageal imaging (UGI) is often used in laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures to confirm anastomotic patency and to exclude leaks. The aim of our study was to assess the usefulness of this practice. From January 2003 to November 2004, 322 LRYGB cases were performed using linear staplers for the gastrojejunostomy and jejuno-jejunostomy anastomoses. As part of our protocol, all patients received a Gastrograffin (Mallinkrodt, Inc., St Louis, Missouri) UGI on postoperative Day 1. The same radiological techniques were used and the same radiological team reviewed all films. Abnormal films were identified. In addition, patient demographics, time to discharge, and complications were collected and analyzed in a prospective database. There were no anastomotic leaks or obstructions. However, 42 of 322 (13%) studies demonstrated delayed gastric emptying. There were no statistically significant differences between patients with normal and delayed UGI studies. Routine UGI studies did not contribute significantly to patient care, and its routine use was subsequently abandoned.     

Successful management of hepatic vein injury from blunt trauma in children

In children, the majority of deaths from blunt trauma to the liver are caused by large stellate fractures of the posterolateral aspect of the right lobe of the liver with extension into the hepatic veins. Four children with such injuries were successfully treated. Hypotension and abdominal tenderness are not early manifestations of this highly lethal injury in children. When an appropriate mechanism for liver injury exists, paracentesis or peritoneal lavage, followed by prompt laparotomy for hemoperitoneum, gives the best chance for early and successful treatment. Large cannulas in arm veins and cross matching for twice the patient's blood volume are used when there is a possibility of a liver injury.The important aspects of operative management are identification of the injury when the abdomen is first opened and prompt control of bleeding. The possibility of hepatic vein injury exists if the surgeon finds the coronary ligament disrupted by a large liver laceration on the posterolateral liver surface. Compressing the liver against the diaphragm will usually control the bleeding while blood replacement is accomplished. The hepatic vein entrance into the inferior vena cava is then exposed using a median sternotomy, if necessary. Partial occlusion of the inferior vena cava can usually be safely done with this direct approach if the blood volume has been restored. Frequently, valuable time and blood are lost if attempts are made to insert internal shunts.     

Nonoperative management of blunt hepatic and splenic injury in children.

OBJECTIVE: The authors assessed the risks of nonoperative management of solid visceral injuries in children (age range, 4 months-14 years) who were consecutively admitted to a level I pediatric trauma center during a 6-year period ending in 1991. METHOD: One hundred seventy-nine children (5.0%) sustained injury to the liver or spleen. Nineteen children (11.2%) died. Of the 160 children who survived, 4 received emergency laparotomies; 156 underwent diagnostic computer tomography and were managed nonoperatively. The percentage of children who were successfully treated nonoperatively was 97.4%. Delayed diagnosis of enteric perforations occurred in two children. Fifty-three children (34.0%) received transfusions (mean volume 16.7 mL/kg); however, transfusion rates during the latter half of the study decreased from 50% to 19% in children with hepatic injuries, despite increasing grade of injury, and decreased from 57% to 23% in the splenic group with similar injury grade (p < 0.005, chi square test and Student's t test). CONCLUSION: Pediatric blunt hepatic and splenic trauma is associated with significant mortality. Nonoperative management based on physiologic parameters, rather than on computed tomography grading of organ injury, was highly successful, with few missed injuries and a low transfusion rate.     

Routine chest X-ray after percutaneous tracheostomy is unnecessary

Percutaneous tracheostomy (PT) is an increasingly common procedure in the management of critically ill patients. Current practice for both open and percutaneous tracheostomies is a post-procedure chest X-ray to rule out potentially life-threatening complications such as a pneumothorax or tube malposition. Our study evaluated the utility of chest X-ray after PT. A retrospective chart review was conducted for patients undergoing PT at Kern Medical Center between January 1999 and December 2003. Charts were reviewed for age, sex, and clinical outcome as well as the radiologist's interpretation of the postprocedure chest X-ray. A total of 73 procedures were completed in 47 men and 26 women. The majority of the tracheostomies were in trauma patients who needed prolonged ventilatory support. There were no complications identified on postprocedure chest X-ray. A single patient was converted to an open procedure secondary to bleeding. We conclude that routine chest X-ray after PT is unnecessary.     

Routine nasogastric decompression is unnecessary after pancreatic resections

Data regarding the use of nasogastric tubes (NGTs) in patients who are undergoing pancreatic resections are limited. We analyzed outcomes after 231 consecutive pancreatectomy procedures in an academic surgical oncology practice. We routinely placed NGTs intraoperatively throughout the first part of the study interval; orogastric tubes (OGTs) were removed intraoperatively before endotracheal extubation whenever possible in the second part of the study (n?=?75 [32%]). The median postoperative NGT duration was 1 day (OGT group, 0 days; NGT group, 2 days [P?相似文献   

Nonoperative management of blunt hepatic trauma

Over the past 15 years, there have been dramatic changes in the management of blunt hepatic trauma, specifically in the imaging techniques, and in the non-operative management. Actually, in more than 80% of blunt hepatic trauma, non operative management is used. In the last 20% the surgical option has to be taken without delay, sometimes in extreme emergency, using the adapted surgical techniques. In this article the author describes the nonoperative management of blunt hepatic trauma: classification, presentation, initial decision, treatment, possible complications and results.     

Study of blunt hepatic injury by ultrasonography

Sixty five consecutive patients with blunt hepatic injury were evaluated retrospectively to assess the clinical usefulness of emergency ultrasonography (US). In 30 patients before introduction of US, five patients (16.7%) were treated nonoperatively since they were hemodynamically stable with negative paracentesis. Another four hemodynamically stable patients were surgically treated due to positive paracentesis. After introduction of US, on the other hand, 17 out of 35 patients (48%) were successfully managed nonoperatively. Furthermore, US revealed small intraperitoneal bleeding and enabled conservative treatment of four hemodynamically unstable patients. There was no change in the management of central liver rupture or Makiya's type III injury. The number of nonoperatively managed cases of Makiya's types I and II increased from 1 to 7 after using US, and that of operative cases decreased from 21 to 12. Thus US was helpful to exactly assess the amount of intraperitoneal bleeding and successfully reduce the number of unnecessary laparotomy. We conclude that US provides useful information to decide early management of blunt hepatic injury.     

Tomographic findings are not always predictive of failed nonoperative management in blunt hepatic injury

BackgroundNonoperative management (NOM) has become the standard treatment of blunt hepatic injury (BHI) for stable patients. Contrast extravasation (CE) on computed tomography (CT) scan had been reported as a sign that is associated with NOM failure. The goal of this study was to further investigate the risk factors of NOM failure in patients with CE on CT scan.MethodsFrom January 2005 to September 2009, patients with CE noted on a CT scan as a result of BHI were studied retrospectively. Physiological parameters, severity of injury, amount of transfusion, type of contrast extravasation, as well as treatment outcome were compared between patients with NOM failure and NOM success.ResultsA total of 130 patients were enrolled. Injury severity scores, amount of blood transfusion before hemostatic procedure, and grade of liver injury were significantly higher in NOM failure than in NOM success patients. There was no statistical difference in the NOM success rate between patients with contrast leakage into the peritoneum and those with contrast confined in the hepatic parenchyma.ConclusionsHigher injury severity score, more blood transfusion, and higher grade of liver injury are factors that correlate with NOM failure in patients with BHI. Contrast leakage into the peritoneum is not always a definite sign of NOM failure in BHI. Early and aggressive angioembolization is an effective adjunct of NOM in BHI patients, even with contrast leakage into peritoneum.     

Isolated blunt trauma injury to the hepatic duct

Isolated bile duct injuries are quite rare. The diagnosis may be difficult. The presence of continued abdominal pain, nausea, vomiting, distention and jaundice in addition to abnormal liver function tests and often a leukocytosis mandate that a biliary tract injury be ruled out. The most important diagnostic study for confirming a biliary tract injury is paracentesis. The ERCP is then done to delineate the anatomy of the injury. Transhepatic cholangiography is an alternative to the ERCP. Treatment for a biliary duct injury must be selected on an individual basis.     

Conservative management of hepatic duct injury after blunt trauma: a case report

Nonoperative management of solid organ injury in children with blunt abdominal trauma represents the standard of care. In rare cases, a major duct injury with persistent bile leakage may result from blunt trauma to the liver. This injury is of concern in patients treated nonoperatively because it generally must be treated with major abdominal surgery. The authors describe a case of hepatic duct injury from blunt trauma in which healing occurred without surgical repair or resection.     

Complications of nonoperative management of pediatric blunt hepatic injury: Diagnosis, management, and outcomes

BACKGROUND: Nonoperative management (NOM) of blunt hepatic injury is the standard of care in the hemodynamically stable pediatric patient, but it is not without pitfalls. The purpose of this study is to assess the incidence and types of complications associated with NOM in terms of diagnosis, management, and outcomes. METHODS: A retrospective study of pediatric patients with blunt hepatic injuries admitted from 1991 through 1997 to a Level I pediatric trauma center was conducted. All stable patients were initially managed nonoperatively according to the Isolated Liver Laceration Critical Pathway. Surveillance was performed by physical examination and tracking of hematocrit and liver function test (LFT) results. Follow-up ultrasound (US) or computed tomography (CT) were performed as clinically indicated. RESULTS: In all, 185 patients with nonoperatively managed blunt hepatic injuries were identified during a 7-year period. Over 90% (168/185) were successfully managed nonoperatively without adverse sequelae. Ten patients (5.4%) died: seven as a result of head injury; three as a result of multisystem organ failure; none directly attributable to their hepatic injuries. Complications occurred in seven patients (3.8%) with Grades III or IV right lobe liver lacerations and included biloma (5), hepatic artery pseudoaneurysm with hemobilia (1), and necrotic gallbladder (1). All seven patients (100%) had fever, persistent or worsening right upper quadrant pain, feeding intolerance, and persistently elevated LFTs. Complications were diagnosed by CT or US. Nonoperative treatment of complications was successful in four of the seven patients (57.1%) and consisted of percutaneous drain placement only (1), percutaneous drain placement and endoscopic retrograde cholangiopancreatography (ERCP)-guided stent placement (2) and angioembolization (1). Three patients (42.9%) required laparotomy, one for management of a concomitant pancreatic pseudocyst. CONCLUSION: Complications of NOM of pediatric blunt hepatic injury are rare, but may include biloma, hepatic artery pseudoaneurysm, and necrotic gallbladder. Complications occur only with Grade III or greater injuries and are accompanied by fever, right upper quadrant pain, feeding intolerance, and persistently elevated LFTs. The clinician must maintain a high index of suspicion for the development of complications and have a low threshold for obtaining a CT or US for diagnosis. Interventional radiology techniques, angiography, and ERCP are useful adjuncts to nonoperative management, but some patients may still require laparotomy for management of complications.     

Routine interval appendectomy is unnecessary after conservative treatment of appendiceal mass

Objective The traditional management of appendiceal mass is initial conservative treatment followed by interval appendicectomy. Recently interval appendicectomy has been questioned by a growing amount of evidence. The purpose of this study was to clarify the role of interval appendicectomy after successful initial conservative treatment. Method The study included 98 patients with a mass in the right iliac fossa. Four (4%) patients were excluded wing to another diagnosis of appendiceal mass including caecal cancer (two), diverticulitis (one), and Crohn’s disease (one). The remaining 94 patients were treated conservatively. Routine interval appendicectomy was not performed after successful conservative treatment. Results Ultrasound (US)‐guided drainage was performed in seven (7.4%) patients. Two were drained surgically because of a persistent abscess despite a previous US‐guided drainage. In five (5.3%) patients, a delayed operation was necessary because of complications. One patient developed small bowel obstruction, and in three patients, conservative treatment was unsuccessful with the abscess remaining unresolved. Within 3 months, seven out of the 89 patients were readmitted to hospital with a recurrent mass in two patients and acute appendicitis without a mass in five patients. Six (6.7%) patients were readmitted with recurrent appendicitis after 3 months. The recurrence rate after successful conservative treatment was 14.6%. The majority (nine patients; 10.1%) of the recurrences occurred within the first 6 months, and after 1 year the recurrence rate was very low (two patients; 2.2%). Conclusion Routine interval appendicectomy after initial successful conservative treatment is not justified and should be abandoned. At present, there is no consensus for the management of appendiceal mass. There is, therefore, a need to develop a protocol for the management of this common problem.     

Routine preoperative laboratory testing in elective pediatric cardiothoracic surgery is largely unnecessary

Objective

Routine preoperative laboratory testing (RLT) is common practice in pediatric cardiothoracic surgery and is associated with significant cost burden to patients and families. We sought to examine the value of RLT in patients undergoing elective pediatric cardiothoracic surgery.
