Hospital care in severe trauma: Initial strategies and life-saving surgical procedures.

Severe trauma patients should be received at the hospital by a multidisciplinary team directed by a "trauma leader" and all institutions capable of receiving such patients should be well organized. As soon as the patient is accepted for care, the entire team should be prepared so that there is no interruption in the pre-hospital chain of care. All caregivers should thoroughly understand the pre-established protocols of diagnostic and therapeutic strategies to allow optimal management of unstable trauma victims in whom hemostasis must be obtained as soon as possible to decrease the morbid consequences of post-hemorrhagic shock. In patients with acute respiratory, circulatory or neurologic distress, several surgical procedures must be performed without delay by whichever surgeon is on call. Our goal is to describe these salvage procedures including invasive approaches to the upper respiratory tract, decompressive thoracostomy, hemostatic or resuscitative thoracotomy, hemostatic laparotomy, preperitoneal pelvic packing, external pelvic fixation by a pelvi-clamp, decompressive craniotomy. All of these procedures can be performed by all practitioners but they require polyvalent skills and training beforehand.

Management of exsanguinating pelvic trauma: Do we still need the radiologist?

BACKGROUND: The hemodynamically unstable pelvic fracture are a diagnostic and therapeutic challenge. The current management is based on the control of pelvic bleeding by combining pelvic ring stabilization and embolization of pelvic arteries. The mortality of these patients, however, exceeds 30%. Recently the preperitoneal packing, based on the hemostatic tamponade of the pelvic cavity has been described. The objective of this study was to evaluate the interest of this new surgical procedure. The effectiveness of the standard algorithm is evaluated by analysis of pelvic injuries in 200 severe trauma treated at the Sainte-Anne Hospital. The results are then compared with literature data on the preperitoneal packing. PATIENTS AND METHODS: The profile injury, management and morbidity and mortality was evaluated in 200 polytrauma. After an initial phase of resuscitation, unstable pelvic fractures were treated with a circumferential belt followed by the application of an external fixator. Arteriography was performed for all patients with persistent hemodynamic instability. RESULTS: The mean injury severity score (ISS) was 31 (4-75). The mean trauma-related injury severity score (TRISS) was 74% (3-99). The proportion of hemodynamically unstable patients was 47%. Fifteen patients (41%) had severe bleeding. The median number of blood transfusion was 10 (4-42); eight patients (22%) underwent embolization. For two patients, reducing the pelvic fracture with an external fixator resulted in permanent hemostasis. Two patients underwent a laparotomy first, for the control of a hemoperitoneum. The mortality rate of the group of patients with hemorrhage was 33% (5/15). DISCUSSION: This high mortality leads to reconsider the place of pelvic embolization as firstline treatment. Some major drawbacks are noted: its effectiveness in treating venous bleeding, availability and duration of the procedure. The preperitoneal packing is a fast and effective surgical alternative. It seems to improve hemodynamic status of patients and significantly reduce the use of embolization and massive transfusion. Embolization is still indicated for patients not responding to surgery. However survival is not significantly improved.

[Pyoderma gangrenosum mimicking abdominal sepsis after colorectal surgery]. / Pyoderma gangrenosum sur un orifice de drainage, pris pour un sepsis abdominal après une chirurgie colorectale.

This study reports a case of pyoderma gangrenosum arising at a drainage orifice after a colostomy for cancer. The initial clinical presentation suggested intra-abdominal sepsis but the clinical assessment did not fit with laboratory findings or the CT scan. Forty hours later, the patient developed a reddish-purple ulcer at the drainage orifice. A diagnosis of pyoderma gangrenosum was made and systemic corticosteroid therapy was started. A dramatic response occurred over the next two days, obviating the need for surgical re-intervention. Pyoderma gangrenosum is an ulcerating necrotizing skin disorder of unknown etiology. It usually arises in association with underlying disease (mainly inflammatory bowel disease) and often occurs in para-stomal sites. Pyoderma gangrenosum arising at surgical sites is often mistaken for a postoperative infection and treated inappropriately with debridement and reopening of the wound which only exacerbates the pathology. Pyoderma gangrenosum is effectively treated with systemic corticosteroids.

[Appendicular pseudo-tumors: unusual diagnosis]. / Pseudo-tumeurs appendiculaires: diagnostics inhabituels.

The discovery of a tumour mass of the appendix, in an acute or chronic context, raises the problem of its benign or malignant, inflammatory or infectious nature. We report five cases of patients operated by the same surgical team between June 1991 and September 1996, who presented macroscopically and histologically with unusual appendicular pseudotumours: appendicular diverticulosis (n = 1), Crohn's disease localized to the appendix (n = 2), yersiniosis (n = 1), actinomycosis (n = 1). The preoperative diagnosis was acute appendicitis (n = 2) or tumour (n = 3). The postoperative course was uneventful in every case, and specific medical treatment was prescribed in two cases (yersiniosis and actinomycosis). These differential diagnoses must be considered in all appendicular diseases, but they are extremely difficult to confirm preoperatively.

[Esophageal perforations and ruptures: a plea for conservative treatment]. / Perforations et ruptures de l'oesophage: plaidoyer pour un traitement conservateur.

OBJECTIVES: To identify the determinants and results on conservative management of oesophageal perforations and ruptures. METHODS: Retrospective clinical review of 34 consecutive patients (mean age: 62 years) treated for cervical (n = 10) or thoracic (n = 24) oesophageal disruption between 1985 and 1996. Causes were: spontaneous rupture (n = 10), instrumental perforation (n = 16), alimentary foreign body (n = 6), and blunt (n = 1) or penetrating trauma (n = 1). The diagnostic delay exceeded 24 hours in 15 cases. RESULTS: A nonoperative management was achieved in 8 patients with no mortality. A conservative surgical treatment was attempted in 23 patients, primary repair in 21 and open drainage in 2, with a 17.4% mortality. Resection (n = 2) or exclusion (n = 1) was performed in 3 patients with no early mortality, but one of them died as result of the subsequent reconstructive operation to restore oesophageal continuity. Overall morbidity was linked to the spontaneous cause of the perforation. Outcome of patients undergoing primary repair was not influenced by the diagnostic delay nor the surrounding sepsis. CONCLUSION: Conservative management should be advocated for the treatment of oesophageal perforations and ruptures, even in case of delayed diagnostiqiagnosis, regardless of the surrounding sepsis and cause of disruption.

[Secreting retroperitoneal paraganglioma. Apropos of a case]. / Paragangliome rétropéritonéal sécrétant. A propos d'un cas.

A case of secreting, asymptomatic retroperitoneal paraganglioma is presented. Paragangliomas are rare neuroendocrine tumors and the malignant behaviour, higher than pheochromocytomas, is based on metastases or local recurrence. The treatment is complete surgical excision. Radiotherapy and chemotherapy may be used for palliation of symptoms.
