Results of combat medic junctional tourniquet training: a prospective, single-blind, randomized, cross-over study.

BACKGROUND: Bleeding remains the leading cause of potentially preventable deaths both in military and civilian pre-hospital trauma settings. Conventional extremity tourniquets do not control bleeding if an iliac artery or a common femoral artery is injured. Stopping junctional bleeding is particularly challenging and requires the use of specifically designed junctional tourniquets. SAM® Junctional Tourniquet (SJT®, United States of America) and Tactical Abdominal Junctional Tourniquet (T-AJT®, Fora Group Türkiye) have been actively used by Turkish security forces. This study questioned the effect of training on combat medics' successful junctional tourniquet applications and application times (AT). METHODS: Our research on two different junctional tourniquet models was designed as a prospective randomized, crossover, single-blinded study. All 40 participants in the study were attendees of a 12-week combat medic training course with updated medical approvals, which were used as an eligibility criterion. Randomization was performed by drawing T-AJT®-SJT cards. The study consisted of pretraining and after-training tourniquet application phases. In each study phase, all participants' AT and the presence or absence of arterial flow were recorded for each group. Finally, the combat medics were presented with a 6-question survey. RESULTS: Although training increased successful T-AJT® application rates, training was not statistically significantly associated with successful applications for any tourniquet types (p>0.05). The pretraining phase ATs for SJT® and T-AJT® were 55±11.8 and 93.8±2.9 seconds, respectively, and the difference was statistically significantly different (p<0.001). Likewise, after-training phase ATs for SJT® and T-AJT® were 49±22.6 and 79.2±17.5 seconds, respectively, and participants' SJT® ATs were significantly shorter (p<0.001). Overall, when participants' applied any of the tourniquet unsuccessfully, the odds of participants' lower Visual Analogue Scale scores were 0.2 (95% CI [0.08, 0.49]. p<0.001). CONCLUSION: Our study basically investigates the effects of training on effective tourniquet application. Unfortunately, our after-training success rates remained unsatisfactory when compared to other studies. This is also the first study on T-AJT® tourniquet application, and further studies on its efficacy are also required.

Injury mechanisms and injury severity scores as determinants of urban terrorism-related thoracoabdominal injuries.

Objectives: Improving the care of injuries resulting from terrorist attacks requires understanding injury mechanisms in armed conflicts. The aim of this study was to identify injury characteristics in military personnel with thoracoabdominal combat injuries resulting from terrorist attacks in urban settings. Material and Methods: A retrospective study of military personnel with thoracoabdominal injuries who were referred to a tertiary center after treating and stabilizing at a primary healthcare organization due to terror-related injuries in various urban regions of Turkey between June 2015 and December 2016 was performed. Results: A total of 70 patients were included in this study, of whom 87.1% were injured by explosives and 12.9% (n= 9) had gunshot wounds (GSWs). Mean injury severity score (ISS) was 21, blood transfusion amount was 3.7 units, and mortality rate was 8.5%. Patients injured by explosives had most commonly abdominal and extremity injuries (31.1%), whereas isolated abdominal injuries (55.6%) were observed among patients with GSWs. There were no significant differences between the mechanisms of injuries and the ISS, blood transfusion, and mortality (p= 0.635, p= 0.634, and p= 0.770, respectively). A significant correlation was observed between the ISS and transfusion amounts (r= 0.548, p <0.001). Mortality was significantly higher in those with a high ISS and those undergoing massive blood transfusions (p= 0.004 and p <0.001, respectively). Conclusion: Explosive injuries, concomitant vascular injuries, high ISS, and the need for massive transfusions increased the mortality rate in urban combat injuries. To quickly identify high-risk patients and improve the care of injuries, it is essential to use predictive models or scoring systems.

BRAF Inhibitors for BRAF V600E Mutant Colorectal Cancers: Literature Survey and Case Report.

The main method of fighting against colon cancer is targeted treatment. BRAF inhibitors, which are accepted as standard treatment for V600E mutant malign melanomas, are the newest approach for targeted treatment of V600E mutant colorectal cancers. In this case report, we share our experience about the use of BRAF inhibitor vemurafenib on a V600E mutant metastatic right colon adenocarcinoma patient. A 59-year-old male with only lung multiple metastatic V600E mutant right colon cancer presented to our clinic. The patient was evaluated and FOLFOX + bevacizumab treatment was initiated, which was then continued with vemurafenib. A remarkable response was achieved with vemurafenib treatment in which the drug resistance occurred approximately in the sixth month. Even though the patient benefited majorly from vemurafenib, he died on the 20th month of the diagnosis. The expected overall survival for metastatic V600E mutant colon adenocarcinoma patients is 4.7 months. BRAF inhibitors provide new treatment alternatives for V600E mutant colorectal cancers, with prolonged overall survival. BRAF inhibitors in combination with MEK inhibitors are reported as feasible treatment to overcome BRAF inhibitor drug resistance on which phase studies are still in progress. To conclude, BRAF inhibitors alone or in combination with other drugs provide a chance for curing BRAF V600E mutant colorectal cancer patients.

Bringing Packed Red Blood Cells to the Point of Combat Injury: Are We There Yet?

Objective: Hemorrhage is the leading cause of injury-related prehospital mortality. We investigated worst-case scenarios and possible requirements of the Turkish military. As we plan to use blood resources during casualty transport, the impact of transport-related mechanical stress on packed red blood cells (PRBCs) was analyzed. Materials and Methods: The in vitro experiment was performed in the environmental test laboratories of ASELSAN®. Operational vibrations of potential casualty transport mediums such as Sikorsky helicopters, Kirpi® armored vehicles, and the NATO vibration standard MIL-STD-810G software program were recorded. The most powerful mechanical stress, which was created by the NATO standard, was applied to 15 units of fresh (≤7 days) and 10 units of old (>7 days) PRBCs in a blood cooler box. The vibrations were simulated with a TDS v895 Medium-Force Shaker Device. On-site blood samples were analyzed at 0, 6, and 24 h for biochemical and biomechanical analyses. Results: The mean (±standard deviation) age of fresh and old PRBCs was 4.9±2.2 and 32.8±11.8 days, respectively. Six-hour mechanical damage of fresh PRBCs was demonstrated by increased erythrocyte fragmentation rates (p=0.015), hemolysis rates (p=0.003), and supernatant potassium levels (p=0.003) and decreased hematocrit levels (p=0.015). Old PRBC hemolysis rates (p=0.015), supernatant potassium levels (p=0.015), and supernatant hemoglobin (p=0.015) were increased and hematocrit levels were decreased (p=0.015) within 6 h. Two (13%) units of fresh PRBCs and none of the old PRBCs were eligible for transfusion after 6 h of mechanical stress. Conclusion: When an austere combat environment was simulated for 24 h, fresh and old PRBC hemolysis rates were above the quality criteria. Currently, the technology to overcome this mechanical damage does not seem to exist. In light of the above data, a new national project is being performed.

Generation of Platelet Microparticles after Cryopreservation of Apheresis Platelet Concentrates Contributes to Hemostatic Activity.

OBJECTIVE: In the last decade, substantial evidence has accumulated about the use of cryopreserved platelet concentrates, especially in trauma. However, little reference has been made in these studies to the morphological and functional changes of platelets. Recently platelets have been shown to be activated by cryopreservation processes and to undergo procoagulant membrane changes resulting in the generation of platelet-derived microparticles (PMPs), platelet degranulation, and release of platelet-derived growth factors (PDGFs). We assessed the viabilities and the PMP and PDGF levels of cryopreserved platelets, and their relation with thrombin generation. MATERIALS AND METHODS: Apheresis platelet concentrates (APCs) from 20 donors were stored for 1 day and cryopreserved with 6% dimethyl sulfoxide. Cryopreserved APCs were kept at -80 °C for 1 day. Thawed APCs (100 mL) were diluted with 20 mL of autologous plasma and specimens were analyzed for viabilities and PMPs by flow cytometry, for thrombin generation by calibrated automated thrombogram, and for PDGFs by enzyme-linked immunosorbent assay testing. RESULTS: The mean PMP and PDGF levels in freeze-thawed APCs were significantly higher (2763±399.4/µL vs. 319.9±80.5/µL, p<0.001 and 550.9±73.6 pg/mL vs. 96.5±49 pg/mL, p<0.001, respectively), but the viability rates were significantly lower (68.2±13.7% vs. 94±7.5%, p<.001) than those of fresh APCs. The mean endogenous thrombin potential (ETP) of freeze-thawed APCs was significantly higher than that of the fresh APCs (3406.1±430.4 nM.min vs. 2757.6±485.7 nM.min, p<0.001). Moreover, there was a significant positive poor correlation between ETP levels and PMP levels (r=0.192, p=0.014). CONCLUSION: Our results showed that, after cryopreservation, while levels of PMPs were increasing, significantly higher and earlier thrombin formation was occurring in the samples analyzed despite the significant decrease in viability. Considering the damage caused by the freezing process and the scarcity of evidence for their in vivo superiority, frozen platelets should be considered for use in austere environments, reserving fresh platelets for prophylactic use in blood banks.

High velocity missile-related colorectal injuries: In-theatre application of injury scores and their effects on ostomy rates.

BACKGROUND: Treatment of colorectal injuries (CRIs) remains a significant cause of morbidity and mortality. The aim of the present study was to analyze treatment trends of Turkish surgeons and effects of the American Association for the Surgery of Trauma (AAST), Injury Severity (ISS), and Penetrating Abdominal Trauma Index (PATI) scoring systems on decision-making processes and clinical outcomes. METHODS: Data regarding high velocity missile (HVM)-related CRIs were retrospectively gathered. Four patient groups were included: Group 1 (stoma), Group 2 (no stoma in primary surgery), Group 2a (conversion to stoma in secondary surgery), and Group 2b (remaining Group 2 patients). RESULTS: Groups 1, 2, 2a, and 2b included 39 (66%), 20 (34%), 6 (30%), and 14 (70%) casualties, respectively. Ostomies were performed in casualties with significantly higher AAST scores (p<0.001). However, PATI and ISS scores were not decisive factors in the performance of ostomy (p=0.61; p=0.28, respectively). Ostomy rates of civilian and military surgeons were 62% and 68%, respectively (p=0.47). Receiver operating characteristic (ROC) analysis showed that AAST score was a more accurate guide for performing ostomy, with sensitivity and specificity rates of 80% and 92.9%, respectively. CONCLUSION: Clinical significance of diversion in HVM-related CRIs remains. Stomas were associated with lower complication rates and significantly higher AAST colon/rectum injury scores.

A simple novel technique for enteroatmospheric fistulae: silicone fistula plug.

Enteroatmospheric fistulae (EAFs), a rare condition that develops in patients treated with an open abdomen, present serious problems for the surgeon. There are no fixed algorithms for treatment of EAF, and treatment options are determined based on the experience of the surgeon and status of the patient. We developed a 'suspended silicone fistula plug' for treating a patient who developed an EAF after undergoing multiple operations in a short period of time. Used in conjunction with negative pressure wound therapy, application of this novel therapy resulted in EAF closure and patient discharge.

Biliary fistula after treatment for hydatid disease of the liver: when to intervene.

AIM: To determine the outcome of patients with biliary fistula (BF) after treatment for hydatid disease of the liver. METHODS: Between January 2000 and December 2010, out of 301 patients with a diagnosis of hydatid cyst of the liver, 282 patients who underwent treatment [either surgery or puncture, aspiration, injection and reaspiration (PAIR) procedure] were analysed. Patients were grouped according to the presence or absence of postoperative biliary fistula (PBF) (PBF vs no-PBF groups, respectively). Preoperative clinical, radiological and laboratory characteristics, operative characteristics including type of surgery, peroperative detection of BF, postoperative drain output, morbidity, mortality and length of hospital stays of patients were compared amongst groups. Multivariate analysis was performed to detect factors predictive of PBF. Receiver operative characteristics (ROC) curve analysis were used to determine ideal cutoff values for those variables found to be significant. A comparison was also made between patients whose fistula closed spontaneously (CS) and those with intervention in order to find predictive factors associated with spontaneous closure. RESULTS: Among 282 patients [median (range) age, 23 (16-78) years; 77.0% male]; 210 (74.5%) were treated with conservative surgery, 33 (11.7%) radical surgery and 39 (13.8%) underwent percutaneous drainage with PAIR procedure A PBF developed in 46 (16.3%) patients, all within 5 d after operation. The maximum cyst diameter and preoperative alkaline phosphatase levels (U/L) were significantly higher in the PBF group than in the no-PBF group [10.5 ± 3.7 U/L vs 8.4 ± 3.5 U/L (P < 0.001) and 40.0 ± 235.1 U/L vs 190.0 ± 167.3 U/L (P = 0.02), respectively]. Hospitalization time was also significantly longer in the PBF group than in the no-PBF group [37.4 ± 18.0 d vs 22.4 ± 17.9 d (P < 0.001)]. A preoperative high alanine aminotransferase level (> 40 U/L) and a peroperative attempt for fistula closure were significant predictors of PBF development (P = 0.02, 95%CI: -0.03-0.5 and P = 0.001, 95%CI: 0.1-0.4), respectively. Comparison of patients whose PBF CS or with biliary intervention (BI) revealed that the mean diameter of the cyst was not significantly different between CS and BI groups however maximum drain output was significantly higher in the BI group (81.6 ± 118.1 cm vs 423.9 ± 298.4 cm, P < 0.001). Time for fistula closure was significantly higher in the BI group (10.1 ± 3.7 d vs 30.7 ± 15.1 d, P < 0.001). The ROC curve analysis revealed cut-off values of a maximum bilious drainage < 102 mL and a waiting period of 5.5 postoperative days for spontaneous closure with the sensitivity and specificity values of (83.3%-91.1%, AUC: 0.90) and (97%-91%, AUC: 0.95), respectively. The multivariate analysis demonstrated a PBF drainage volume < 102 mL to be the only statistically significant predictor of spontaneous closure (P < 0.001, 95%CI: 0.5-1.0). CONCLUSION: Patients with PBF after hydatid surgery often have complicated postoperative course with serious morbidity. Patients who develop PBF with an output < 102 mL might be managed expectantly.

[The affecting factors on the complication ratio in abdominal gunshot wounds]. / Karin içi atesli silah yaralanmalarinda komplikasyon oranlarini etkileyen faktörler.

BACKGROUND: We aimed to investigate the affecting factors on the complication ratio in abdominal gunshot wounds. METHODS: Twenty-one patients with abdominal gunshot wounds were analyzed between February 2002 and May 2005. The effects of the interval between trauma and presentation to the hospital, the number of injured abdominal and extra-abdominal organs, penetrating abdominal trauma index (PATI), and blood transfusion were evaluated. RESULTS: 90.4% of all patients were transported to the hospital and underwent their first evaluation in the first two hours. The complication rate was 7.1% in patients who had <3 injured organs and 71% in the others (p<0.0001). 71.4% of the patients had isolated abdominal trauma, while 28.6% had additional extra-abdominal organ trauma. The complication rate was 7.7% in 13 patients with PATI score <25 and 62.5% in 8 patients with a PATI score ≥25 (p<0.0001). In 10 patients who underwent blood transfusion of ≥3 units, the complication rate was 50% (p<0.0001). CONCLUSION: In our study, PATI score, multiple blood transfusions and the number of injured intra-abdominal organs were the most important factors affecting the rate of postoperative complications in penetrating abdominal gunshot wounds. We found that the interval between trauma and presentation to the hospital and number of injured extra-abdominal organs did not affect the complication rate.

Ultrasonography accurately evaluates the dimension and shape of the pilonidal sinus.

PURPOSE: To study the benefits of ultrasonography for detecting the borders of pilonidal sinus tissue. The correlation between physical and ultrasonographic examination was used for surgical planning. METHOD: Between April and December 2004, 73 patients were recruited for this study. All patients were examined, and the borders of the sinus tissue were marked on the skin according to palpation before surgery. The surgeon also made a treatment plan considering the diseased tissue and marked a possible incision line. Patients were subsequently examined with ultrasonography. According to the ultrasonographic evaluation, the margins, extensions, and openings of pilonidal sinus tissue were determined and marked on the patient in a different color by a radiologist prior to surgery. The most suitable surgical treatment was decided according to the information obtained by ultrasonography. RESULTS: The average age was 23.03 +/- 3.05 (range 18-39) years. We found 81 lesions in 73 patients. Ultrasonographic borders of sinus tissue were similar to the borders marked by the surgeon in 56 patients (76.7%). In the remaining 17 patients (23.3%), ultrasonography detected branches or borders that distinctly exceeded the planned incision line. After ultrasonographic examination, the surgeon changed his incision line in 14 patients and the surgical intervention in 3 patients. CONCLUSION: Palpation and methylene blue injection do not provide appropriate information in many patients. Our study revealed that pre-operative ultrasonography can improve the identification of the sinus tract and its branches when compared to palpation and methylene blue injection.

The handmade endoloop technique. A simple and cheap technique for laparoscopic appendectomy.

OBJECTIVE: To compare 2 laparoscopic appendectomy techniques. METHODS: We describe a modified technique, the handmade endoloop technique, for closing the base of the appendix. This prospective study was carried out at Harran University Medical Faculty, Sanliurfa, and Gulhane Military Medical Academy, Ankara, Turkey from September 2006 to February 2008. We evaluated the safety and efficacy of the procedure in 98 acute appendicitis cases: 57 patients handmade endoloop patients, and 41 endoloop technique patients. Operative time, postoperative complications, need for analgesics, and procedure cost were measured for both groups. The endoloops and sutures used to manage appendectomy were listed at current prices, summarized as number consumed per case, and compared. Data were analyzed by appropriate test. RESULTS: The average price of material used for closing the base of appendix was 81 American Dollars (USD) for laparoscopic appendectomy with endoloop, and 8 USD for the technique described by this article. Overall, postoperative complications, operative time, and the need for analgesia did not show a statistical difference in comparing both groups. CONCLUSION: This procedure is simple, safe, and cheap.

Stump appendicitis, rare complication after appendectomy: report of a case.

Appendectomy is one of the most common procedures in surgical practice. Stump appendicitis is an acute inflammation of the residual part of the appendix and a rare complication of incomplete appendectomy. It may present clinically as acute abdomen. We report a case of stump appendicitis 12 years after open appendectomy. After the diagnosis of acute appendicitis, the patient was operated and discharged from the hospital four days after operation without any complications. Stump appendicitis is a rare cause of acute abdomen and should be taken into consideration in the differential diagnosis.

Comparison of modified darn repair and Lichtenstein repair of primary inguinal hernias.

OBJECTIVE: This study was designed to compare the results of the Modified Darn Repair through Lichtenstein procedure in inguinal hernias. MATERIALS AND METHODS: The study involved 322 patients with inguinal hernia, operated in General Surgery Departments of Gulhane Military Medical Academy and Sirnak Military Hospital between 1998 and 2004. The durations of operation time, hospitalization, and time to return to daily activities and postoperative complication and recurrence rates were evaluated. Lichtenstein procedure was applied on 170 patients (Group 1), and modified darn repair was applied on 152 patients (Group 2). RESULTS: The average follow-up period was 56 months. For the Lichtenstein procedure, the average duration of operation was 56 min; the average time to return to routine activities was 20 days. The number of patients with postoperative complications was 20 (11.7%), and the number of patients with recurrence was 1 (0.6%). For modified darn repair, the average duration of operation was 48 min; the time to return to daily activities was 20 days. The number of patients with postoperative complication was three (1.9%), and no recurrences were noted. The hospitalization time of the groups was similar. DISCUSSION: Modified darn repair is a reliable method for inguinal hernia repair with short hospitalization time, low rate of postoperative complications, and recurrence.

Can SAPS II predict operative mortality more accurately than POSSUM and P-POSSUM in patients with colorectal carcinoma undergoing resection?

BACKGROUND: This study assessed the APACHE II (Acute Physiology and Chronic Health Evaluation II), SAPS II (Simplified Acute Physiology Score-II), POSSUM (Physiologic and Operative Severity Score for Enumeration of Morbidity and Mortality), and P-POSSUM (Portsmouth-POSSUM) in patients with colorectal cancer undergoing curative or palliative resection. METHODS: Predicted mortality rates and the observed/expected mortality ratio were computed by means of each scoring system. The results were compared between survivors and nonsurvivors and between elective and emergency operations. Each model was assessed for its accuracy to predict the risk of death using receiver operator characteristic (ROC) curve analysis, and risk stratification was generated as well. RESULTS: Some 224 patients were enrolled in the study. The overall 30-day mortality rate was 3.6% (n = 8). Predicted mortality rates generated by APACHE II, SAPS II, POSSUM, and P-POSSUM were 9.1%, 3.7%, 13.4%, and 5.2%, respectively. All the scoring systems assigned higher scores to those patients who died than to those who survived. Areas under the curve calculated by ROC curve analysis for APACHE II, SAPS II, POSSUM, and P-POSSUM were 0.786, 0.854, 0.793, and 0.831, respectively. Best stratification was achieved by the SAPS II score. CONCLUSIONS: SAPS II and P-POSSUM were determined to be better predictors for patients with colorectal cancer undergoing resection. SAPS II also was found to have a higher degree of discriminatory power in colorectal resection for carcinoma. The predictive value of this useful severity score in several surgical subgroups must be examined to evaluate its routine use in risk-adjusted audit.

D-dimer levels in the prediction of the degree of intestinal necrosis of etrangulated hernias in rats.

PURPOSE: The aim of this study was to investigate the time-dependent relation between plasma D-dimer levels and the degree of intestinal necrosis and to compare these parameters with leukocyte counts in an experimental etrangulated hernia model in rats. RESULTS: When the duration of intestinal ischemia was prolonged, serum D-dimer levels increased relative to the control group, with the difference being statistically significant at hour 2 (P = 0.027). In contrast, leukocyte counts in the 2- and 4-h strangulation group were higher that those of the control group, but the difference was not statistically significant (P = 0.625 and P = 0.846, respectively). However, in the 6-h strangulation group the levels of leukocytes were significantly higher that those of the control group (P = 0.015). CONCLUSION: Serum D-dimer measurements may be used as a more valuable diagnostic parameter than leukocyte count in the early diagnosis of intestinal ischemia, including strangulated hernia.

Appropriate approach to bronchobiliary fistulas: a case series with hydatid disease and algorithm of case-based management.

Bronchobiliary fistula caused by liver echinococcosis is a relatively unusual but severe complication of hydatid disease. Optimal management of cases is crucially important in establishing rapid recovery and avoiding additional complications. The use of an algorithmic guide is essential because of an ongoing dilemma that involves a large variety of therapeutic options. We present four patients with bronchobiliary fistulas caused by liver hydatid disease to discuss the management of therapeutic options through a case-based approach and an extent review to finally generate an algorithm. In this series, two patients were treated surgically, and the remaining were treated with conservative methods. To date, they have developed neither recurrence nor need for additional intervention. Although treatment of bronchobiliary fistulas is traditionally thought to be surgical, most of the less severe cases can be treated nonoperatively. Making an accurate selection among less invasive methods and/or open surgical interventions seems to be a key component of management.

Extrahepatic abdominal hydatid disease caused by Echinococcus granulosus: imaging findings.

OBJECTIVE: The classical findings in hydatid disease caused by Echinococcus granulosus with liver or lung involvement are well known. However, diagnosing hydatid disease at unusual locations may be challenging because of variable imaging appearances depending on the host reaction. The purpose of this pictorial essay is to review the sonographic, CT, and MRI features of extrahepatic abdominal hydatid disease including intraperitoneum, retroperitoneum, diaphragma, bone, and soft tissue of the abdomen. CONCLUSION: Extrahepatic abdominal hydatid lesions have nearly identical imaging features, including the presence of cyst wall calcification, daughter cysts, and membrane detachment. The combinations of radiologic and serologic tests especially in patients living in the endemic areas contribute to the diagnosis. Despite their rarity, being familiar with the spectrum of radiologic findings in these unusual sites is helpful to improve diagnostic accuracy.

Isolated torsion of fallopian tube in a premenarcheal 12-year-old girl.

Isolated torsion of fallopian tubes should be considered even at premenarcheal ages in cases of acute pelvic pain, and prompt surgery can preserve the tube and thus fertility. It is an uncommon emergency event and a difficult condition to evaluate clinically. This report focuses on a 12-year-old premenarcheal girl who presented with acute pelvic pain of 2 days. Pelvic ultrasound showed an adnexal mass on the left side. Laparoscopy was performed and an isolated tubal torsion was discovered. The tube was necrotic and salpingectomy was performed. The appendix appeared to be hyperemic and erectile. Appendectomy was also performed to rule out appendicitis. It's our recommendation that in the differential diagnosis of acute lower abdominal pain of girls, isolated torsion of the fallopian tubes should be considered. Also, preservation of the tube and fertility should be possible with prompt surgical intervention.
