PURPOSE: This study aimed to investigate the incidence and risk factors of early postoperative small bowel obstruction (EPSBO) after laparotomy for trauma patients. METHODS: From 2009 to 2016, consecutive patients who had undergone laparotomy for trauma were retrospectively evaluated. EPSBO was defined as the presence of signs and symptoms of obstruction between postoperative days 7 and 30, or obstruction occurring anytime within 30 days and lasting more 7 days. RESULTS: Among 297 patients who met the inclusion criteria, 72 (24.2%) developed EPSBO. The length of hospital stay was significantly longer in patients with EPSBO than in those without EPSBO (median [interquartile range], 34 [21–48] days 24 [14–38] days, P < 0.001). Multivariate logistic analysis identified male sex (adjusted odds ratio [AOR], 3.026; P = 0.008), intraoperative crystalloid (AOR, 1.130; P = 0.031), and Abbreviated Injury Scale (AIS) score for mesenteric injury (AOR, 1.397; P < 0.001) as independent risk factors for EPSBO. The incidence of adhesive small bowel adhesion after 30 days postoperatively did not significantly differ between the 2 groups (with EPSBO, 5.6% without EPSBO, 5.3%; P = 0.571). Most of the patients with EPSBO were recovered by conservative treatment (95.8%). CONCLUSION: After laparotomy for trauma patients, the incidence of EPSBO was 24.2% in our study. EPSBO was associated with a longer hospital stay. Male sex, use of intraoperative crystalloid, and AIS score for mesenteric injury were significant independent risk factors for EPSBO. Patients with these risk factors should be followed-up more carefully.

Purpose:
The occurrence of trauma-related delirium following postoperative abdominal surgery is associated with a poor prognosis. The purpose of this study was to identify predictive risk factors for trauma-related delirium.
Methods:
Trauma patient data from a regional trauma center were retrospectively collected from August 2015 to December 2016. The primary inclusion criteria were patients diagnosed with traumarelated delirium following abdominal trauma surgery. Head trauma patients and those under 18 years of age were excluded from this study. A multivariate logistic regression analysis was performed to identify the risk factors associated with trauma-related delirium.
Results:
Of the 255 trauma patients who met the inclusion criteria, 32 (12.5%) were diagnosed with delirium. The mean values for the age of the patients, Injury Severity Score, Glasgow Coma Scale score, and length of intensive care unit stay were 52.1 ± 17.8 years, 16.9, 14, and 7.1 days, respectively. Among the measured parameters, age [odds ratio (OR), 1.03; 95% confidence interval (CI), 1.01-1.06; p = 0.022)], sex (OR, 0.125; 0.03-0.55; p = 0.006), hemoglobin level (OR, 0.875; CI, 0.68-0.98; p = 0.03), length of stay in the intensive care unit (OR, 1.12; CI, 1.03-1.22; p = 0.01), and having an abdominal operation (OR, 2.92; CI, 1.10-7.23; p = 0.011) showed strong correlations with trauma-related delirium.
Conclusion
This study showed that abdominal surgery was strongly associated with delirium in patients with traumatic abdominal injury. Thus, changes in consciousness should be carefully monitored following surgery.

Mucosal-associated invariant T (MAIT) cells and natural killer T (NKT) cells are known to play important roles in autoimmunity, infectious diseases and cancers. However, little is known about the roles of these invariant T cells in multiple trauma. The purposes of this study were to examine MAIT and NKT cell levels in patients with multiple trauma and to investigate potential relationships between these cell levels and clinical parameters. The study cohort was composed of 14 patients with multiple trauma and 22 non-injured healthy controls (HCs). Circulating MAIT and NKT cell levels in the peripheral blood were measured by flow cytometry. The severity of injury was categorised according to the scoring systems, such as Acute Physiology and Chronic Health Evaluation (APACHE) II score, Simplified Acute Physiology Score (SAPS) II, and Injury Severity Score (ISS). Circulating MAIT and NKT cell numbers were significantly lower in multiple trauma patients than in HCs. Linear regression analysis showed that circulating MAIT cell numbers were significantly correlated with age, APACHE II, SAPS II, ISS category, hemoglobin, and platelet count. NKT cell numbers in the peripheral blood were found to be significantly correlated with APACHE II, SAPS II, and ISS category. This study shows numerical deficiencies of circulating MAIT cells and NKT cells in multiple trauma. In addition, these invariant T cell deficiencies were found to be associated with disease severity. These findings provide important information for predicting the prognosis of multiple trauma.

Hemorrhage is a major cause of death in trauma patients. The medical definition of hemorrhagic shock is tissue hypoperfusion resulting from a reduction of blood volume. Decreased blood pressure resulting from acute blood loss induces cardiac stimulation, systemic vasoconstriction, and volume redistribution. These effects are due to the baroreceptor reflex, the humoral compensatory mechanisms including the renin angiotensin system, and the release of catecholamine and vasopressin. Hemorrhagic shock causes acidosis, hypothermia, and coagulopathy, known as ‘the lethal triad.’ Tissue hypoxia induces metabolic acidosis by producing lactic acid. The three components of the lethal triad amplify each other and form a vicious cycle, eventually causing the death of the patient. To reduce the risk of mortality in severely bleeding patients, we need to understand the pathophysiology of hemorrhagic shock and the related complications.

PURPOSE: Splenic injury management has shifted to non-surgical treatment to preserve the spleen because of the postoperative risks of overwhelming post-splenectomy infection. In this study, we analyzed risk factors of therapeutic options for splenic injury, using medical records of Chonnam National University Hospital. METHODS: We reviewed the medical records of 110 consecutive patients with traumatic splenic injuries admitted from January 2009 to December 2013. Demographic characteristics and therapeutic options such as conservative treatment, angiographic embolization and emergency operation and clinical parameters were analyzed in this study. RESULTS: Thirty-four patients were treated surgically and seventy-six were managed with nonsurgical treatment. Multivariate logistic regression identified age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.009~1.072; p=0.01), hematocrit (OR, 0.878; 95% CI, 0.806~0.957; p=0.003), contrast extravasation (OR, 7.644; 95% CI, 2.248~25.986; p=0.001), spleen grade (OR, 2.08; 95% CI, 1.128~ 3.836; p=0.019) as significant risk factors of emergent splenectomy. CONCLUSION: Age, hematocrit, contrast extravasation, spleen grade were significant risk factors for emergent splenectomy.

PURPOSE: Pancreatic trauma is infrequent because of its central, deep anatomical position. This contributes to a lack of surgeon experience and many debates exist about its standard care. This study aimed to investigate the postoperative pancreatic fistula (POPF) and mortality of pancreatic trauma after operation. METHODS: We reviewed records in the trauma registry of our institution submitted from January 2006 to December 2016. The grade of pancreatic injury, surgical management, morbidity, mortality, and other clinical variables included in the analyses. RESULTS: Data from a total of 26,072 trauma patients admitted to the Emergency Department were analyzed. Pancreatic trauma was observed in 114 of these patients (0.44%). Laparotomy was performed in 81 patients (2 pan creatico duodenectomies, 2 pancreaticogastrostomies, peripancreatic drainage in 41 patients, distal pancreatectomies in 34 patients, and 9 patients who underwent surgery for damage control). The incidence of POPF was 38.3%. The overall mortality was 8.8% (7 of 81). In multivariate analysis, pancreas injury grade IV (≥4) (adjusted odds ratio [AOR], 4.071; P = 0.029) and preoperative peritonitis signs (AOR, 2.903; P = 0.039) were independent risk factors for POPF. All patients who died had also another major abdominal injury (≥grade 3). Multiorgan failure was a major cause of death (6 of 7, 85.7%). The mortality rate of isolated pancreas injury was 0%. CONCLUSION: The pancreas injury grade and preoperative peritonitis were significant risk factors of POPF. The mortality rate of isolated pancreatic trauma was very low.

PURPOSE: We investigated the pattern of regional recurrence pattern of intrathyroidal node negative - T1N0 or T2N0 - papillary carcinoma, focusing on skip versus continuous central and lateral lymph node metastasis. Most lymph node metastasis of papillary thyroid carcinoma appear in a step-wise sequential pattern, but discontinuous lymph node metastasis may occur in 11.1~37.5% in node positive papillary cancer. While skip metastasis has been studied on the synchronous central and lateral lymphatic clearance, it has not been studied in reoperative settings on lateral recurrence. METHODS: From January 2000 to December 2005, Two hundred and seventy-five T1/T2 N0 patients underwent reoperative lymphatic clearance after total thyroidectomy and clinical - not prophylactic - central neck dissection in Gwangju and Hwasoon Chonnam National University Hospitals. We enrolled 210 patients who showed central and lateral neck metastasis as the continuous recurrence group and 65 patients who showed lateral metastasis without central lymph node metastasis as the skip recurrence group. RESULTS: Skip metastasis occurred in 17.6% (9/27 patients), and skip recurrence was in 23.6% (65/275 patients). In univariate analysis, in case of a single lesion, the skip recurrence was more prone to occur than multiple (P=0.026) and bilateral (P=0.048) papillary carcinoma. Multivariate analysis showed that tumor less than 1 cm (OR=2.24, P=0.009), single lesion (OR=3.23, P=0.019) for multiple lesion, and (OR=2.22, P=0.025) for bilateral lesion. CONCLUSION: Skip metastases were found in 17.6% (9 out of 27) of patients, and skip recurrence in reoperative surgery was found in 23.6% (65 out of 275) of patients. Careful follow-up and low dose radioiodine therapy may be considered in T1N0 or T2N0 papillary carcinoma in selected patients.
