The aim of this prospective study was to examine whether serum neurotensin, interleukin (IL)-6, and IL-8 are early predictor of bowel ischaemia especially in clinically equivocal cases. To this end, 56 patients were assigned to the following groups according to their disease: bowel ischaemia (group 1: n = 14), small bowel obstruction (group 2: n = 12), acute inflammation (group 3: n = 6), perforation (group 4: n = 8), and colorectal adenocarcinoma (group 5: n = 16). Fifteen healthy controls were assigned to group 6. Blood samples were obtained at enrollment, all measurements were done blindly, and all patients underwent surgery. Pretreatment doubtful diagnosis comprised of ileus, mild abdominal pain, and indeterminate imaging. Blood urea nitrogen, lactic acidosis, diagnostic workup, and IL-6 were predictors of diagnosis in univariate analysis. In multivariate analysis, IL-6 (P < 0.001) and diagnostic workup (P < 0.01) were independent predictors of the definite diagnosis. Neurotensin and IL-8 did not differentiate among groups. Considering clinically doubtful cases, IL-6 perfectly differentiates mesenteric ischaemia (of infarction/embolic/occlusive aetiology) from the rest of the indeterminate pathologies. The optimum cut-off point for IL-6 was 27.66 pg/mL. The value of serum IL-6 (27.66 pg/mL) had sensitivity = 1 and specificity = 1. In conclusion, plasma IL-6 measurement on admission might be an additional diagnostic tool that can predict bowel ischaemia in doubtful clinical situations.

Epidemiology and management of trauma patients in a Greek multispecialty hospital in the absence of a dedicated trauma center

PURPOSE/OBJECTIVE:In the absence of dedicated trauma centers, surgical emergency departments in hospitals assigned as trauma centers accept a huge load of trauma patients. In this audit, we aim to document and assess the epidemiologic data of trauma patients and their injuries in order to give a picture of the impact of trauma in the workload of a surgical department in the Greek healthcare system. METHODS:During a period of 2 years, we managed 6,041 trauma patients in the accident and emergency (A&E) department based on the Advanced Trauma Life Support (ATLS) protocols. We retrospectively reviewed the emergency department registry and the admissions. RESULTS:47.56 % of the patients seen in the A&E department were trauma patients. The mean age of the trauma patients was 44.52 years (range 15-106 years). The majority were men (60.4 %). The leading cause of trauma was motor and vehicle accidents, followed by slip and fall accidents, physical assault, fall from height, and vehicle pedestrian accidents. The majority of the patients were discharged from the hospital. Only 29 (4.6 %) out of 624 patients who were admitted to the general surgery department underwent an operation, while the rest were admitted for observation. On the other hand, patients were admitted to other departments only when surgical treatment was necessary. CONCLUSIONS:In the absence of level one trauma centers, in multispecialty urban hospitals, the coordination of trauma burdens the general surgery team. This has financial and administrative implications. The collection of important epidemiologic data from these hospitals is mandatory in order to develop national prevention measures against injuries.

Laparoscopic versus open appendicectomy in Greek reality

Lanitis, Sophocles; Korontzi, Maria; Sgourakis, George; Karkoulias, Kyriakos; Kontovounisios, Christos; Karaliotas, Constantine
Laparoscopic appendicectomy (LA) may be the treatment of choice for acute appendicitis. Our aim was to assess LA in Greek reality. Within a year, 135 patients with a mean age of 29.25 years (14 to 67) underwent an operation for "acute appendicitis." We analyzed the hospital stay, the morbidity, the cost, and the severity of the inflammation and compared the open appendicectomy [OA (78)] with the LA (57) approach. There were no differences in the appendicitis severity (P = 0.667), and similar complication rate (P = 0.414) and mean hospital stay were observed between the groups (LA = 3.18 vs. OA = 2.97, P = 0.664). In the way, medical procedures are priced in Greece; the mean net cost of LA was 1320.60 euros (1748.05 USD), whereas for OA, it was 237.8 euros (314.77 USD). The severity of appendicitis is not a limitation for LA. Because of an insufficient costing system in Greece, the best cost effectiveness is for young women and obese men.

Severe monobacterial necrotizing soft tissue infection by group A Streptococcus: A surgical emergency [Case Report]

Lanitis, S; Khan, M A A; Sgourakis, G; Kontovounisios, C; Papaconstandinou, T; Karaliotas, C
Eight percent of necrotizing soft tissue infections (NSTI) are attributable to group A Streptococci (GAS), and among these, 50% develop streptococcal toxic shock syndrome. The reported mortality associated with NSTI reaches 32%. We present cases of two healthy individuals with minor GAS skin infection which developed to a rapidly progressed NSTI and sepsis despite of the antibiotic treatment, aiming to discuss the lessons learned from the course and management of these patients.
