An uncommon and easily overlooked case: Delayed intraperitoneal bladder rupture following blunt trauma: A case report and review of the literature.

INTRODUCTION: Delayed intraperitoneal bladder rupture is a rare clinical occurrence, frequently overlooked and misdiagnosed due to its nonspecific clinical manifestations. However, literature provides only a limited number of cases reporting delayed intraperitoneal bladder rupture resulting from blunt abdominal injury. PATIENT CONCERNS: A 72-year-old female pedestrian was struck by a vehicle and experienced sudden, severe abdominal pain on the 8th day following the injury. Abdominal B-ultrasound revealed a significant accumulation of peritoneal effusion. The abdominal puncture retrieved serosanguinous ascites. Then the patient was promptly transferred to our hospital. Upon transfer, the physical examination revealed the patient vital signs to be stable, accompanied by mild abdominal distension, slight tenderness, tension, and an absence of rebound tenderness. Urinalysis detected microscopic hematuria, while contrast-enhanced computed tomography (CT) revealed considerable fluid accumulation in the abdominal cavity, without evidence of solid organ damage, and the bladder was adequately filled. DIAGNOSIS: The diagnosis of delayed intraperitoneal bladder rupture primarily relied on intraoperative observations. INTERVENTIONS: An emergency exploratory laparotomy was performed, revealing a linear rupture at the dome of the bladder. Subsequently, the bladder rupture was repaired. OUTCOMES: Postoperative cystography demonstrated full recovery and the patient was discharged 28 days post-surgery. The postoperative recovery was uneventful without any complications. CONCLUSIONS: A well-distended bladder observed in CT does not definitively rule out the potential for bladder injury. False negatives may occur due to incomplete bladder filling during CT cystography. Retrograde cystography can identify cases missed by CT cystography. In cases of substantial intra-abdominal free fluid, surgical intervention should be actively considered for patients with blunt abdominal trauma without concurrent solid organ damage.

Surgical management of duodenal injury: experience from 92 cases.

PURPOSE: Duodenal injury increases with traffic accidents, and delayed diagnosis or inappropriate operation increase mortality and complications. This study aimed to explore early recognition and timely surgical intervention. METHODS: All patients with duodenal injuries treated operatively during the past 10 years were reviewed, and the data were analyzed retrospectively regarding the mechanism of injury, diagnostic and therapeutic methods, and outcome. RESULTS: A total of 92 patients with duodenal injuries accounted for 7.3% of 1258 patients with abdominal injury. Of the 92 patients, 71 (77.17%) experienced blunt trauma, with traffic accidents accounting for 59.2% (42/71). In 35 patients, a preoperative diagnosis was obtained by reviewing abdominal signs, peritoneocentesis, and imaging. The remaining 57 patients underwent urgent laparotomy, through which a definitive diagnosis of duodenal injury was confirmed during the operation. In all 92 patients, the surgical procedures involved simple sutures; pedicled jejunal piece coverings; and various anastomoses following resection of the injured duodenal portion, including the Whipple procedure and damage-control surgery principles. The overall mortality rate was 12.0% (11/92) with deaths mainly occurring due to associated injuries. When excluding 2 cases of intraoperative death, there were 47 cases in the double-tube gastrostomy group and 43 cases in the traditional triple-tube group, with mortality rates of 10.64% and 9.30% in the two groups, respectively (χ2 = 0.045, P > 0.05). Postoperative complications occurred in 15 patients (18.5%). There was a high incidence of duodenal (or pancreatic/biliary) leakage. CONCLUSION: Early diagnosis and operation of duodenal injury are crucial to reducing complications and mortality. Surgical methods should be based on injury grade, associated injuries, and vital signs. Double-tube gastrostomy can reduce complications such as intestinal obstruction.

Management and outcome of bronchial trauma due to blunt versus penetrating injuries.

BACKGROUND: The number of patients with bronchial trauma (BT) who survived to hospital admission has increased with the improvement of prehospital care; early diagnosis and treatment should be considered, especially among blunt trauma patients, whose diagnosis is frequently delayed. AIM: To describe the early recognition and surgical management considerations of blunt and penetrating BTs, and to elaborate the differences between them. METHODS: All patients with BTs during the past 15 years were reviewed, and data were retrospectively analyzed regarding the mechanism of injury, diagnostic and therapeutic procedures, and outcomes. According to the injury mechanisms, the patients were divided into two groups: Blunt BT (BBT) group and penetrating BT (PBT) group. The injury severity, treatment procedures, and prognoses of the two groups were compared. RESULTS: A total of 73 patients with BT were admitted during the study period. The proportion of BTs among the entire cohort with chest trauma was 2.4% (73/3018), and all 73 underwent thoracotomy. Polytrauma patients accounted for 81.6% in the BBT group and 22.9% in the PBT group, and the mean Injury Severity Score was 38.22 ± 8.13 and 21.33 ± 6.12, respectively. Preoperative three-dimensional spiral computed tomography (CT) and/or fiberoptic bronchoscopy (FB) were performed in 92.1% of cases in the BBT group (n = 38) and 34.3% in the PBT group (n = 35). In the BBT group, a delay in diagnosis for over 48 h occurred in 55.3% of patients. In the PBT group, 31 patients underwent emergency thoracotomy due to massive hemothorax, and BT was confirmed during the operation. Among them, 22 underwent pulmo-tractotomy for hemostasis, avoiding partial pneumonectomy. In this series, the overall mortality rate was 6.9% (5/73), and it was 7.9% (3/38) and 5.7% (2/35) in the BBT group and PBT group, respectively (P > 0.05). All 68 survivors were followed for 6 to 42 (23 ± 6.4) mo, and CT, FB, and pulmonary function examinations were performed as planned. All patients exhibited normal lung function and healthy conditions except three who required reoperations. CONCLUSION: The difference between blunt and penetrating BTs is obvious. In BBT, patients generally have no vessel injury, and the diagnosis is easily missed, leading to delayed treatment. The main cause of death is ventilation disturbance due to tension pneumothorax early and refractory atelectasis with pneumonia late. However, in PBT, most patients require emergency thoracotomy because of simultaneous vessel trauma and massive hemothorax, and delays in diagnosis are infrequent. The leading cause of death is hemorrhagic shock.

Blunt Cardiac Injury: A Single-Center 15-Year Experience.

In recent years, the incidence of blunt cardiac injury (BCI) has increased rapidly and is an important cause of death in trauma patients. This study aimed to explore early diagnosis and therapy to increase survival. All patients with BCI during the past 15 years were analyzed retrospectively regarding the mechanism of injury, diagnostic and therapeutic methods, and outcome. The patients were divided into two groups according to the needs of their condition-nonoperative (Group A) and operative (Group B). Comparisons of the groups were performed. A total of 348 patients with BCI accounted for 18.3 per cent of 1903 patients with blunt thoracic injury. The main cause of injury was traffic accidents, with an incidence of 48.3 per cent. In Group A (n = 305), most patients sustained myocardial contusion, and the mortality was 6.9 per cent. In Group B (n = 43), including those with cardiac rupture and pericardial hernia, the mortality was 32.6 per cent. Comparisons of the groups regarding the shock rate and mortality were significant (P < 0.01). Deaths directly resulting from BCI in Group B were greater than those in Group A (P < 0.05). In all 348 patients, the mortality rate was 10.1 per cent. When facing a patient with blunt thoracic injury, a high index of suspicion for BCI must be maintained. To manage myocardial contusion, it is necessary to protect the heart, alleviate edema of the myocardium, and control arrhythmia with drugs. To deal with those requiring operation, early recognition and expeditious thoracotomy are essential.

Emergency Surgery for Blunt Cardiac Injury: Experience in 43 Cases.

BACKGROUND: Blunt cardiac injury (BCI) increases with traffic accidents and is an important cause of death in trauma patients. In particular, for patients who need surgical treatment, the mortality rate is extremely high unless the patient is promptly operated on. This study aimed to explore early recognition and expeditious surgical intervention to increase survival. METHODS: All patients with BCIs during the past 15 years were reviewed, and those who underwent operative treatment were analyzed retrospectively regarding the mechanism of injury, diagnostic and therapeutic methods, and outcome. RESULTS: A total of 348 patients with BCIs accounted for 18.3% of 1903 patients with blunt thoracic injury (BTI). Of 348 patients, 43 underwent operative treatment. The main cause of injury was traffic accidents, with an incidence of 48.8%. Of them, steering wheel injuries occurred in 15 patients. In 26 patients, a preoperative diagnosis was obtained by echocardiography, CT scanning, etc. In the remaining 17, who had to undergo urgent thoracotomy without any preoperative imaging, a definitive diagnosis of BCI was proven during the operation. The volume of preoperative infusion or crystalloid was <1000 ml in 31 cases. Preoperative pericardiocentesis was not used in anyone. In 12 patients, the operation commenced within 1 h. Overall mortality was 32.6%. The death was caused by BCI in 9. CONCLUSIONS: Facing a patient with BTI, a high index of suspicion for BCI must be maintained. To manage those requiring operations, early recognition and expeditious thoracotomy are essential. Preoperatively, limited fluid resuscitation is emphasized. We do not advocate preoperative pericardiocentesis.

Polytrauma with thoracic and/or abdominal injuries: experience in 1 540 cases.

OBJECTIVE: To investigate the early diagnosis and treatment of polytrauma patients with thoracic and/or abdominal injuries. METHODS: The data of all polytrauma patients with thoracic and/or abdominal injuries during the past 10 years were studied retrospectively. RESULTS: In the present study, there were 1 540 polytrauma patients, accounting for 65.0% of all 2 368 trauma patients. Of these patients, 62.4% were in shock state on admission. The operative rates were 15.0% (181/1 206) and 79.9% (612/766) in patients with thoracic and abdominal injury (P<0.01), 5.2% (39/758) and 31.7% (142/448) in patients with blunt and penetrating chest trauma (P<0.01), and 72.45% (359/496) and 93.7% (253/270) in patients with blunt and penetrating abdominal injuries (P<0.01), respectively. To deal with abdominal injury, angioembolization was performed in 43 cases, with 42 cured. The overall mortality rate was 6.2%. And in the blunt and penetrating subgroups, the mortalities were 7.9% (75/950) and 3.6% (21/590), respectively (P<0.01). Most patients died from exsanguination. CONCLUSIONS: The first "golden hour" after trauma should be grasped, since the treatment in this hour can determine greatly whether the critically-injured victim could survive. Prompt diagnosis and proper treatment contribute more greatly to the survival of the victim than the severity of injury.

[Management of severe pelvic fracture associated with injuries of viscera].

OBJECTIVE: To probe the approach of emergency management for severe pelvic fracture associated with injuries of adjacent viscera and evaluate the therapeutic effect. METHODS: The data of 79 patients with severe pelvic fracture associated with injuries of adjacent viscera were retrospectively studied, and the study covered a period of 14 years. RESULTS: Ligation of internal iliac arteries was performed in 33 cases for ceasing massive bleeding due to pelvic fracture, and angioembolization in 8. Of 42 patients with cystic or/and urethral injury, 35 underwent cystostomy and delayed reconstruction, and 7 received a primary realignment. All of 17 patients with injury of retroperitoneal rectum underwent diverting colostomy of the proximal end of sigmoid with presacral drainage, but 4 received primary repair without colostomy. In 22 patients with intraperitoneal colorectal injury, 19 were managed with primary repair or anastomosis while 3 received a colostomy. The overall mortality rate was 9% (7/79); The main causes were hemorrhagic shock and associated injury. The complications included urethro-rectal fistula in 4, thrombosis of right common iliac artery in 1, acute respiratory distress syndrome (ARDS) following chest trauma in 1, and paraplegia in 1. Except the patient with paraplegia, all of them were cured. CONCLUSIONS: Prompt diagnosis and proper treatment were the key of the success. Devascularization of internal iliac arteries with external fixation cage of pelvis, cystostomy and proximal sigmoidostomy were effective procedures frequently used in the emergency treatment of the severe pelvic fracture patients.

Penetrating cardiac wounds: principles for surgical management.

Stab wounds are the main type of penetrating cardiac injury in China and they have a fairly good prognosis when the patient receives expeditious and appropriate management. The objective of this study is to present the experience of managing the patients with penetrating cardiac injuries. A retrospective study involving 82 cases with penetrating wounds of the heart in the past 16 years was carried out. Stab wounds accounted for 86.58% of this series (71 of 82 patients). All 82 cases were treated operatively. The amount of preoperative infusion as fluid resuscitation for shock was less than 1,000 ml in 65.85% of the present study. Only in three patients was preoperative pericardiocentesis performed, yielding a false-negative result in one. Six patients sustaining cardiac arrest soon after arrival were subjected to emergency room thoracotomy (ERT), and five of them survived. The overall survival rate was 96.34%. One patient died of exsanguination due to injury of multiple chambers; of the remaining 2 deaths after operation 1 was associated with abdominal injuries and the other with failure of cerebral resuscitation. From the experience reported in this study, early establishment of diagnosis and prompt thoracotomy against time are the fundamental factors affecting the outcome of penetrating cardiac injuries. Preoperative massive transfusion and pericardiocentesis are not advocated.
