Educational Review of Predictive Value and Findings of Computed Tomography Scan in Diagnosing Bowel and Mesenteric Injuries After Blunt Trauma: Correlation With Trauma Surgery Findings in 163 Patients.

BACKGROUND AND AIMS: Laparotomy can detect bowel and mesenteric injuries in 1.2%-5% of patients following blunt abdominal trauma. Delayed diagnosis in such cases is strongly related to increased risk of ongoing sepsis, with subsequent higher morbidity and mortality. Computed tomography (CT) scanning is the gold standard in the evaluation of blunt abdominal trauma, being accurate in the diagnosis of bowel and mesenteric injuries in case of hemodynamically stable trauma patients. Aims of the present study are to 1) review the correlation between CT signs and intraoperative findings in case of bowel and mesenteric injuries following blunt abdominal trauma, analysing the correlation between radiological features and intraoperative findings from our experience on 25 trauma patients with small bowel and mesenteric injuries (SBMI); 2) identify the diagnostic specificity of those signs found at CT with practical considerations on the following clinical management; and 3) distinguish the bowel and mesenteric injuries requiring immediate surgical intervention from those amenable to initial nonoperative management. MATERIALS AND METHODS: Between January 1, 2008, and May 31, 2010, 163 patients required laparotomy following blunt abdominal trauma. Among them, 25 patients presented bowel or mesenteric injuries. Data were analysed retrospectively, correlating operative surgical reports with the preoperative CT findings. RESULTS: We are presenting a pictorial review of significant and frequent findings of bowel and mesenteric lesions at CT scan, confirmed intraoperatively at laparotomy. Moreover, the predictive value of CT scan for SBMI is assessed. CONCLUSIONS: Multidetector CT scan is the gold standard in the assessment of intra-abdominal blunt abdominal trauma for not only parenchymal organs injuries but also detecting SBMI; in the presence of specific signs it provides an accurate assessment of hollow viscus injuries, helping the trauma surgeons to choose the correct initial clinical management.

Nonoperative management of blunt splenic injury in adults: there is (still) a long way to go. The results of the Bologna-Maggiore Hospital trauma center experience and development of a clinical algorithm.

Non-operative management (NOM) of hemodynamically stable patients with blunt splenic injury (BSI) is the standard of care, although it is associated with a potential risk of failure. Hemodynamically unstable patients should always undergo immediate surgery and avoid unnecessary CT scans. Angioembolization might help to increase the NOM rates, as well as NOM success rates. The aim of this study was to review and critically analyze the data from BSI cases managed at the Maggiore Hospital Trauma Center during the past 5 years, with a focus on NOM, its success rates and outcomes. A further aim was to develop a proposed clinical practical algorithm for the management of BSI derived from Clinical Audit experience. During the period between January 1, 2009 and December 31, 2013 we managed 293 patients with splenic lesions at the Trauma Center of Maggiore Hospital of Bologna. The data analyzed included the demographics, clinical parameters and characteristics, diagnostic and therapeutic data, as well as the outcomes and follow-up data. A retrospective evaluation of the clinical outcomes through a clinical audit has been used to design a practical clinical algorithm. During the five-year period, 293 patients with BSI were admitted, 77 of whom underwent immediate surgical management. The majority (216) of the patients was initially managed non-operatively and 207 of these patients experienced a successful NOM, with an overall rate of successful NOM of 70 % among all BSI cases. The success rate of NOM was 95.8 % in this series. All patients presenting with stable hemodynamics underwent an immediate CT-scan; angiography with embolization was performed in 54 cases for active contrast extravasation or in cases with grade V lesions even in absence of active bleeding. Proximal embolization was preferentially used for high-grade injuries. After a critical review of the cases treated during the past 5 years during a monthly clinical audit meeting, a clinical algorithm has been developed with the aim of standardizing the clinical management of BSI by a multidisciplinary team to include every patient within the correct diagnostic and therapeutic pathway, in order to improve the outcomes by potentially decreasing the NOM failure rates and to optimize the utilization of resources.

The NOTA Study (Non Operative Treatment for Acute Appendicitis): prospective study on the efficacy and safety of antibiotics (amoxicillin and clavulanic acid) for treating patients with right lower quadrant abdominal pain and long-term follow-up of conservatively treated suspected appendicitis.

OBJECTIVES: To assess the safety and efficacy of antibiotics treatment for suspected acute uncomplicated appendicitis and to monitor the long term follow-up of non-operated patients. BACKGROUND: Right lower quadrant abdominal pain is a common cause of emergency department admission. The natural history of acute appendicitis nonoperatively treated with antibiotics remains unclear. METHODS: In 2010, a total of 159 patients [mean AIR (Appendicitis Inflammatory Response) score = 4.9 and mean Alvarado score = 5.2] with suspected appendicitis were enrolled and underwent nonoperative management (NOM) with amoxicillin/clavulanate. The follow-up period was 2 years. RESULTS: Short-term (7 days) NOM failure rate was 11.9%. All patients with initial failures were operated within 7 days. At 15 days, no recurrences were recorded. After 2 years, the overall recurrence rate was 13.8% (22/159); 14 of 22 patients were successfully treated with further cycle of amoxicillin/clavulanate. No major side effects occurred. Abdominal pain assessed by the Numeric Rating Scale and the visual analog scale; median Numeric Rating Scale score was 3 at 5 days and 2 after 7 days. Mean length of stay of nonoperatively managed patients was 0.4 days, and mean sick leave period was 5.8 days. Long-term efficacy of NOM treatment was 83% (118 patients recurrence free and 14 patients with recurrence nonoperatively managed). None of the single factors forming the Alvarado or AIR score were independent predictors of failure of NOM or long-term recurrence. Alvarado and AIR scores were the only independent predictive factors of NOM failure after multivariate analysis, but both did not correlate with recurrences. Overall costs of NOM and antibiotics were &OV0556;316.20 per patient. CONCLUSIONS: Antibiotics for suspected acute appendicitis are safe and effective and may avoid unnecessary appendectomy, reducing operation rate, surgical risks, and overall costs. After 2 years of follow-up, recurrences of nonoperatively treated right lower quadrant abdominal pain are less than 14% and may be safely and effectively treated with further antibiotics.

Changes in the outcomes of severe trauma patients from 15-year experience in a Western European trauma ICU of Emilia Romagna region (1996-2010). A population cross-sectional survey study.

BACKGROUND: Our experience in trauma center management increased over time and improved with development of better logistics, optimization of structural and technical resources. In addition recent Government policy in safety regulations for road traffic accident (RTA) prevention, such compulsory helmet use (2000) and seatbelt restraint (2003) were issued with aim of decreasing mortality rate for trauma. INTRODUCTION: The evaluation of their influence on mortality during the last 15 years can lead to further improvements. METHODS: In our level I trauma center, 60,247 trauma admissions have been recorded between 1996 and 2010, with 2183 deaths (overall mortality 3.6 %). A total of 2,935 trauma patients with ISS >16 have been admitted to Trauma ICU and recorded in a prospectively collected database (1996-2010). Blunt trauma occurred in 97.1 % of the cases, whilst only 2.5 % were penetrating. A retrospective review of the outcomes was carried out, including mortality, cause of death, morbidity and length of stay (LOS) in the intensive care unit (ICU), with stratification of the outcome changes through the years. Age, sex, mechanism, glasgow coma scale (GCS), systolic blood pressure (SBP), respiratory rate (RR), revised trauma score (RTS), injury severity score (ISS), pH, base excess (BE), as well as therapeutic interventions (i.e., angioembolization and number of blood units transfused in the first 24 h), were included in univariate and multivariate analyses by logistic regression of mortality predictive value. RESULTS: Overall mortality through the whole period was 17.2 %, and major respiratory morbidity in the ICU was 23.3 %. A significant increase of trauma admissions has been observed (before and after 2001, p < 0.01). Mean GCS (10.2) increased during the period (test trend p < 0.05). Mean age, ISS (24.83) and mechanism did not change significantly, whereas mortality rate decreased showing two marked drops, from 25.8 % in 1996, to 18.3 % in 2000 and again down to 10.3 % in 2004 (test trend p < 0.01). Traumatic brain injury (TBI) accounted for 58.4 % of the causes of death; hemorrhagic shock was the death cause in 28.4 % and multiple organ failure (MOF)/sepsis in 13.2 % of the patients. However, the distribution of causes of death changed during the period showing a reduction of TBI-related and increase of MOF/sepsis (CTR test trend p < 0.05). Significant predictors of mortality in the whole group were year of admission (p < 0.05), age, hemorrhagic shock and SBP at admission, ISS and GCS, pH and BE (all p < 0.01). In the subgroup of patients that underwent emergency surgery, the same factors confirmed their prognostic value and remained significant as well as the adjunctive parameter of total amount of blood units transfused (p < 0.05). Surgical time (mean 71 min) showed a significant trend towards reduction but did not show significant association with mortality (p = 0.06). CONCLUSION: Mortality of severe trauma decreased significantly during the last 15 years as well as mean GCS improved whereas mean ISS remained stable. The new safety regulations positively influenced incidence and severity of TBI and seemed to improve the outcomes. ISS seems to be a better predictor of outcome than RTS.

Management and outcome of 308 cases of liver trauma in Bologna Trauma Center in 10 years.

INTRODUCTION: Management of Liver Trauma may vary widely from NOM +/- angioembolization to Damage Control Surgery. Multidisciplinary management is essential for achieving better outcomes. MATERIAL AND METHODS: During 2000-2009 period 308 patients with liver injury were admitted to level 1 trauma center and recorded in Trauma Registry. Collected data are demographics, AAST grade, initial treatment (operative or non-operative treatment) and outcome (failure of NOM), death. All patients were initially assessed according to ATLS guidelines. In case of haemodynamic instability and FAST evidence of intra-abdominal free fluid, the patients underwent immediate laparotomy. Hemodynamically stable patients, underwent CT scan and were admitted in ICU for NOM. RESULTS: Two hundred fourteen patients (69.5%) were initially managed with NOM. In 185 patients this was successful. Within the other 29 patients, failure of NOM was due to liver-related causes in 12 patients and non-liver-related causes in 17 Greater the grade of liver injury, fewer patients could be enrolled for NOM (85.8% in I-II and 83.3% in III against 39.8% in IV-V). Of those initially treated non-operatively, the likelihood of failure was greater in more severely injured patients (24.4% liver-related failure rate in IV-V against the 1.3% and 1.0% in I-II and III respectively). One hundred twenty-three patients (40% of the whole population study--308 patients) underwent laparotomy: 94 immediately after admission, because no eligible for NOM; 29 after NOM failure . In the 81 patients in which liver bleeding was still going on at laparotomy, hemostasis was attempted in two different ways: in the patients affected by hypothermia, coagulopathy and acidosis, perihepatic packing was the treatment of choice. In the other cases a "direct repair" technique was preferred. "Early mortality" which was expected to be worse in patients with such metabolic derangements, was surprisingly the same of the other group. This proves efficacy of the packing technique in interrupting the "vicious cicle" of hypothermia, coagulopathy and acidosis, therefore avoiding death ("early death" in particular) from uncontrollable bleeding. CONCLUSION: NOM +/- angioembolization is safe and effective in any grade of liver injury provided hemodynamic stability. DCS is Gold Standard for hemodynamically unstable patients.

Packing for damage control of nontraumatic intra-abdominal massive hemorrhages.

BACKGROUND: The Damage Control Surgery (DCS) approach to massive intraperitoneal hemorrhage has been shown to significantly reduce the morbidity and mortality in severely injured trauma patients. We applied the same principles to patients who developed a massive hemorrhage and the "lethal triad" (acidosis, hypothermia, coagulopathy) during a surgical procedure in order to assess feasibility and efficacy of DCS on nontraumatic grounds. METHODS: A retrospective analysis of eight consecutive cases was performed aimed at collecting information on laboratory parameters, fluids requirements, operative times, APACHE II score, damage control surgery procedure, angioembolization, morbidity, mortality, and need for repacking. RESULTS: Average APACHE II score was 25.5 (predicted mortality rate = 54%); overall and early mortality in the nontraumatic group was nil, while the intra-abdominal septic (packing-related) complication rate was 12.5%. CONCLUSIONS: Intra-abdominal packing was shown to be feasible, safe, and effective for patients with intra-abdominal nontraumatic massive hemorrhage, and the application of the principles of DCS may improve survival in cases of surgical hemorrhage with development of the lethal triad.

[The Elhers-Danlos syndrome: an insidious pathology. Presentation of a familiary group]. / La sindrome di Elhers-Danlos: una patologia insidiosa. Presentazione di un gruppo familiare.

INTRODUCTION: Elhers-Danlos Syndrome (EDS) is an hereditary disease of the connective tissue, which may have clinical appearances varying in its severity from subclinical asymptomatic forms up to dramatic uncontrollable haemorrhage. MATERIALS AND METHODS: We have observed three siblings who were carriers of vascular type EDS. They were otherwise healthy at the time of the disease presentation and have become symptomatic since then, developing severe and uncontrollable haemorrhage. RESULTS: We have reported the clinical presentation of this syndrome, the clinical and laboratory characteristics, the treatment and the outcome. CONCLUSIONS: Although the severity of this disease, Elhers-Danlos Syndrome becomes symptomatic lately and suddenly in its course, often during emergency surgery for haemorrhagic shock. Several issues are raised such as the possibility for early diagnosis of this disease, the psychological features of a genetic counseling, the need for the patients to have adequate lifestyle and last but not least the risk of genetic transmission of the disease.

[Penetrating abdominal trauma: 20 years experience in a Western European Trauma Center]. / Traumi penetranti dell'addome. Esperienza di 20 anni in Trauma Center dell'Europa Occidentale.

BACKGROUND: The incidence of penetrating abdominal trauma in Western Europe is low. While non-operative management of blunt trauma has become the gold standard, the management of penetrating trauma is still controversial. Nonoperative management (NOM) and laparoscopy are currently used in selected patients, reducing the rate of unnecessary laparotomy. METHODS: We retrospectively reviewed a 20-years period from the Trauma Registry of our Trauma Center. 6523 patients were admitted for thoraco-abdominal trauma (5861 blunt vs 662 penetrating). We sorted the 114 patients with penetrating abdominal trauma in 2 groups for period (1989-2000 vs 2001-08, before and after the establishment of dedicated trauma unit) analyzing their demographics, clinical, therapeutic characteristics and the outcome in comparison. RESULTS: In the latest period a significant increase in the incidence of penetrating trauma has been observed (doubled from 4.17/year up to 8.53/year, accounting now for 13.95% of all trauma laparotomies vs 7.8% in the past decade). A reduction of GSW (30% vs 12.5%, p = ns) occurred while no differences have been recorded in sex, age, prognostic parameters at arrival such as mean GCS (11.8 vs 13.2), ISS (22 vs 18), pH, BE and blood transfusion (6.4 vs 4.3 U) requirement. Interestingly a markedly significant change has been observed in the demographics of the victims (67.2% were of extra-EU origin vs 8% in the previous decade, p < 0.01). Recently the use of NOM spread widely in selected stable patients (21.9%). The failure rate of NOM was 14.3%. The percentage of unnecessary laparotomies decreased from 36% to 21.1% (p = ns). The introduction of laparoscopy was helpful in achieving a reliable, less invasive exploration, allowing detection of the peritoneal penetration and complete visceral exploration. Two GSW (4%) vs 3 (5.8%) cases of the latest years required Damage Control Surgery. A recent significant reduction in mortality and morbidity rate has been recorded (respectively 3.85% vs 18%, p < 0.05; 20% vs 39%, p = ns). CONCLUSION: The recent immigration phenomenon and social changes contributed towards a significant rise in the incidence of penetrating trauma in Italy in the last decade associated to changes in the mechanism of injury. The increased use of NOM and laparoscopy contributed in decreasing the incidence of unnecessary laparotomies as well as overall morbidity and mortality.

[The damage control surgery]. / Damage control surgery: orientamenti attuali.

AIM OF THE STUDY: To evaluate our experience in the treatment of complex abdominal injuries with the principles of Damage Control Surgery (DCS). METHOD: A retrospective review was conducted of 55 patients with multiple abdominal injuries and severe haemorrhage induced hypothermia and acidosis admitted to the "Ospedale Maggiore Trauma Center" in Bologna from 1989 to June 2005. RESULTS: All the patients but one had major blunt trauma. Mean age was 40.1; mean ISS 42; mean RTS 4.11; extimated loss of blood was greater than 4000 ml. Packing provide definitive control of bleeding in 44 patients but 10 had recurrent bleeding or bleeding from different injuries such as bone fractures and required further surgery (2) or arterial embolization (8). Twenty eights patients (50.9%) died. Survival was strongly associated with the ISS, GCS, the loss of blood and acidosis. CONCLUSION: The Authors concluded that in selected circumstances the traditional approach to severe abdominal injuries is not appropiate. In this situation, alternative and aggressive treatment such as the Damage Control Surgery has been recommended as the procedure of choice.

[The education of the trauma surgeon: the "trauma surgery course" as advanced didactic tool]. / Modelli educazionali in chirurgia del trauma: il "Corso Teorico-Pratico di Chirurgia del Politrauma" come proposta di didattica avanzata.

BACKGROUND: The consequences of low incidence of penetrating injuries in Europe and of the increasing in nonoperative management of blunt trauma are a decrease in surgeons' confidence for managing traumatic injuries. The Corso Teorico Pratico di Chirurgia del Politrauma was developed as model for teaching operative trauma techniques. The aim of this retrospective study is to evaluate the effectiveness of the course and compare it with other similar courses. METHOD: The Corso Teorico Pratico di Chirurgia del Politrauma is a two day course and consists of lecture on trauma topics and porcine operative experience. Data on the first 124 participants were collected and analyzed. RESULTS: One hundred twenty general surgeons and 2 pediatric surgeons had participated at the course. All the participants judged the course an efficient model to improve knowledge on surgical treatment of trauma. CONCLUSION: A two days course, focused on trauma, with didactic lectures and operative life-like situations, can be a model for simulated education and useful to improve surgeons' confidence in trauma patients.

[Diagnosis and treatment of retroperitoneal traumatic injuries. Our experience on 221 patients]. / Le lesioni traumatiche del retroperitoneo: inquadramento diagnostico e terapeutico. Nostra esperienza su 221 pazienti.

BACKGROUND: The management of traumatic retroperitoneal injuries is still confusing to many surgeons. The presence of injuries of retroperitoneum generally worsens the prognosis in trauma patients and need more attention both the diagnosis and treatment and mortality is high comparated to abdominal traumati injuries. METHOD: A retrospective review was conducted of 221 patients with retroperitoneal injuries admitted to the Ospedale Maggiore Trauma Center in Bologna from 1989 to March 2005. RESULTS: Two hundred seven were blunt traumas and 14 penetrating. Mean age was 40.3; 25 patients died in operating room and 25 were treated with Damage Control Surgery for both abdominal and retroperitoenal injuries. The mortality rate was 15%. Data about surgical treatments, associate treatments for abdominal injuries, and need of reoperation are reported. CONCLUSION: Retroperitoneal traumatic injuries are challenging emergencies and need of attention and expertise by the suorgeon. Only with a careful judgement on the tactics and the procedure to carry on it is possible to gain valid results, which often means to safe the patients life.

Advances in laparoscopy for acute care surgery and trauma.

The greatest advantages of laparoscopy when compared to open surgery include the faster recovery times, shorter hospital stays, decreased postoperative pain, earlier return to work and resumption of normal daily activity as well as cosmetic benefits. Laparoscopy today is considered the gold standard of care in the treatment of cholecystitis and appendicitis worldwide. Laparoscopy has even been adopted in colorectal surgery with good results. The technological improvements in this surgical field along with the development of modern techniques and the acquisition of specific laparoscopic skills have allowed for its utilization in operations with fully intracorporeal anastomoses. Further progress in laparoscopy has included single-incision laparoscopic surgery and natural orifice trans-luminal endoscopic surgery. Nevertheless, laparoscopy for emergency surgery is still considered challenging and is usually not recommended due to the lack of adequate experience in this area. The technical difficulties of operating in the presence of diffuse peritonitis or large purulent collections and diffuse adhesions are also given as reasons. However, the potential advantages of laparoscopy, both in terms of diagnosis and therapy, are clear. Major advantages may be observed in cases with diffuse peritonitis secondary to perforated peptic ulcers, for example, where laparoscopy allows the confirmation of the diagnosis, the identification of the position of the ulcer and a laparoscopic repair with effective peritoneal washout. Laparoscopy has also revolutionized the approach to complicated diverticulitis even when intestinal perforation is present. Many other emergency conditions can be effectively managed laparoscopically, including trauma in select hemodynamically-stable patients. We have therefore reviewed the most recent scientific literature on advances in laparoscopy for acute care surgery and trauma in order to demonstrate the current indications and outcomes associated with a laparoscopic approach to the treatment of the most common emergency surgical conditions.

Different possible surgical managements of caustic ingestion: diagnostic laparoscopy for Zargar's grade 3a lesions and a new technique of "Duodenal Damage Control" with "4-tubes ostomy" and duodenal wash-out as an option for extensive 3b lesions in unstable patients.

In the present study, we have described two possible approaches in the management of caustic injuries. Diagnostic emergency laparoscopy can be used for exploration in case of stable patients with Zargar's 3a gastric lesions and equivocal peritoneal signs. On the other hand, in case of patients with Zargar's 3b gastric lesions with perforation, diffuse peritonitis and hemodynamic instability, a new possible technique is described as an option to be used in such extensive caustic injuries: duodenal damage control with "4-tubes ostomy" for duodenal and jejunal wash-out of the caustic agent. The aim of this simple technique is to wash-out the caustic agent from the duodenum when the duodenum and Treitz are not yet gangrenous/perforated, as well as to avoid duodenal primary closure and jejuno-jejunal anastomosis over damaged tissues.

A Challenging Misleading Diagnosis in a Patient with Suspicion of Gastric Banding Slippage and Strangulation: Diagnosis and Laparoscopic Treatment.

A 51-year-old female (height 160 cm, weight 89 kg, BMI 34.8) presented at the emergency department complaining of sudden onset of sharp abdominal pain in the epigastrium, colicky in nature, dysphagia, nausea, and repeated retching with non-productive vomiting. She has had an adjustable gastric banding implanted laparoscopically 11 years earlier. Since then, she reported to have had only a moderate weight loss (initial BMI 44), although she was closely followed up and the reservoir properly filled by her obesity surgeon. A gastrografin was performed and showed no clear signs of slippage of the gastric band nor of gastric strangulation/ischemia. Nonetheless, the passage of the contrast through esophagogastric junction was slightly slow and restricted suggesting a moderate stenosis from the band. Two cubic centimeters of saline were aspirated from the reservoir to loosen the gastric band. However, on the following minutes, no significant relief of the sharp pain was observed. NSAIDS and morphine were repeatedly given without significant pain relief, and after a few hours, the pain was more intense and diffused to the upper abdomen. I.V. contract CT scan showed a large amount of free fluid, with severe small bowel distension and suspected volvulus and a transition point at the port site of the reservoir, suggesting a strangulated incisional hernia on this site and/or strangulating band adhesion. Urgent surgery was planned, and a laparoscopic approach was chosen. A large amount of free bloody fluid was found, and a long segment of small bowel was twisted around a strangulating band adhesion on the port site of the reservoir, incarcerated within an incisional hernia on the same port site. The strangulating band was cut, and the strangulated bowel was released. Gradual reversion of bowel ischemia was observed, and the gastric banding was removed according to the patient's preoperative request.
