Several reports have indicated the benefits of the acute care surgery (ACS) model in surgical outcomes. We tried to delineate the impact of the ACS model on surgical efficiency and quality.Before the ACS model was implemented, abdominal surgical emergencies were evaluated by an on-call nontrauma general surgeon (pre-ACS model). An in-house trauma surgeon treated all patients with trauma or nontrauma abdominal surgical emergencies after the ACS model. Patients with acute appendicitis who underwent appendectomies were included. We conducted a pre- and poststudy to compare the time patients were in the emergency department and surgical qualities.There were 146 and 159 patients enrolled in the pre-ACS model and ACS model, respectively. The overall ED length of stay in the ACS model was significantly shorter than that in the pre-ACS model (300.3 ± 61.7 vs 719.1 ± 339.0 minutes, P.001). Hospital LOS was also significantly shorter in the ACS model than in the pre-ACS model (2.44 ± 1.39 vs 3.83 ± 2.21 days, P = .022).The ACS model may improve abdominal surgical efficiency and quality. Our study results echoed the benefits of the implementation of the ACS model shown in North America.

Background Nonoperative 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. Methods From 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. Results A 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. Conclusions Higher 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.

Background Angioembolization is an effective adjunct in the management of high-grade renal injuries not surgically treated. However, in some cases, the bleeding may stop spontaneously, without the need for embolization. The aim of this study was to define the characteristics of patients who need angioembolization for high-grade blunt renal injuries (BRIs). Methods Patients with BRIs between January 2004 and May 2008 were retrospectively reviewed. Patients with contrast extravasation on computed tomographic scans who then underwent angiography were enrolled. Demographics, injury severity scores, abbreviated injury scale scores, amounts of blood transfused, and need for angioembolization were analyzed. Results Twenty-six patients were enrolled. Patients with discontinuity of Gerota's fascia and pararenal hematoma expansion in BRIs required angioembolization at a higher rate. Furthermore, these patients displayed higher injury severity scores and abbreviated injury scale scores. Five patients experienced complications. Conclusions In patients with BRIs, discontinuity of Gerota's fascia and pararenal hematoma expansion seemed to be associated with the need for angioembolization. Early angioembolization should be considered in patients with severe associated trauma with BRIs.

Background Because of the difficulties in preoperative diagnosis and controversies in the management, cecal diverticulitis has received much discussion in the literature. There, however, are still many questions that remain unanswered. Methods During a 5-year period, 112 patients with a clinical diagnosis of cecal diverticulitis were treated. Twenty-seven patients were excluded because of uncertainty in diagnosis or incomplete data collection, leaving 85 patients as the study group. The diagnosis of cecal diverticulitis was made by pathology, surgical findings, or image study. Results Nonoperative management was applied to 18 patients initially. Three patients had recurrent diverticulitis during follow up. These patients responded satisfactorily to another course of medical treatment. Laparotomy was performed in 67 patients. Acute appendicitis was the preoperative diagnosis in 47 patients (70%). Of the other 20 patients, 6 received operation because of repeated attack of diverticulitis, 7 had preoperative computed tomography (CT) diagnosis of cecal diverticulitis with perforation, 5 had preoperative diagnosis of cecal tumor, and 2 had medical treatment failure. All these 20 patients received right hemicolectomy. In the 47 patients with a preoperative diagnosis of acute appendicitis, 24 received appendectomy, 9 received diverticulectomy, and 14 received right hemicolectomy. Overall, 34 patients received right hemicolectomy, 9 received diverticulectomy, and 24 received appendectomy only. In the right hemicolectomy group, there were 2 deaths with underlying diseases and 5 complications. In the appendectomy group, there was no postoperative mortality, but in 7 patients recurrent diverticulitis developed. Three of them required right hemicolectomy. Conclusions The natural history of cecal diverticulitis varies from benign and self-limiting to fulminant in the oriental population. Less than 40% (32 of 85) of patients were successfully treated with conservative methods initially and had no recurrence during the follow-up period. We recommend aggressive surgical resection for patients with a definite diagnosis. Adjuvant appendectomy without resection of the lesion should be considered only in uncomplicated patients whose diagnosis is in doubt.

Background: Bladder injuries constitute one of the most common urological injuries involving the lower urinary tract. The methods of diagnosis and management of bladder trauma have been well established and accepted. However, bladder injuries are usually associated with other major injuries, and it is our concern here how bladder injuries have been managed as part of multiple trauma. Methods: From 1991 to 2000, a total of 51 cases of bladder injury were retrospectively reviewed. The mechanisms of trauma, types of bladder injury, time needed to diagnosis, methods of treatment, and patient outcome, were analyzed. Diagnosis time was defined as the time interval from patient arrival to the establishment of a diagnosis either by image studies or laparotomy. Management followed the general rule that bladder contusions or extraperitoneal ruptures were treated non-operatively, and that those with intraperitoneal rupture or combined rupture underwent operative repair. If bladder injury was noted after the patient left the emergency room (ER), it was defined as a delay diagnosis. The Injury Severity Score (ISS), length of hospital stay, and morbidity were used to evaluate patient outcome. Results: The mean age of all the patients was 31.4 years old, and most of them had sustained an injury from a motor vehicle accident (40 of 51). All but 3 patients had gross hematuria. Ten of the patients underwent emergency laparotomy, and 2 of them underwent emergency neurosurgical procedures, therefore no image studies were performed for these 12 patients. A total of 33 patients underwent abdominal computed tomography (CT), but only 20 were correctly diagnosed, yielding an accuracy rate of 60.6%. There were 3 delay diagnoses, due to either a lack of gross hematuria on presentation or the patient leaving the ER before any bladder injury study could be performed. A retrograde cystogram was performed in 24 patients, with an accuracy rate of 95.9% (23 of 24). The mean diagnosis time of the 48 bladder injuries presented in the ER was 3.2 hours and the time needed to reach a diagnosis was not related to the severity of bladder injury. Those patients who underwent operation immediately did not seem to have a quicker diagnosis. Those patients with a higher injury score (ISS >16), and those patients who suffered from pelvic fracture, stayed in the hospital longer. However, the severity of the bladder injury was not related to the length of hospital stay. There was no bladder-related mortality in our series. Conclusions: We report our results of dealing with bladder injuries from the point of view of trauma surgeons who treat bladder injury as part of multiple injuries. Although known as a procedure of choice for diagnosis of bladder injury, the retrograde cystogram was performed in fewer than half of the patients (24 of 51), which means it is not feasible in many situations. The patient outcome was determined by the severity of injury of the patient but not by the severity of bladder injury.
