    ABSTRACT: BACKGROUND: We aimed to assess the pediatric trauma score analysis in pediatric trauma cases due to shrapnel effect of explosives material with high kinetic energy. METHODS: The data of 17 pediatric injuries were reviewed retrospectively between February 2002 and August 2005. The information about age, gender, trauma-hospital interval, trauma mechanism, the injured organs, pediatric Glasgow coma score (PGCS), pediatric trauma score (PTS), hemodynamic parameters, blood transfusion, interventions and length of hospital stay (LHS) were investigated. RESULTS: While all patients suffered from trauma to the extremities, only four patients had traumatic lower-limb amputation. Transportation time was <=1 hour in 35% of cases, and >1 hour in 65% of cases. While PTS was found as <=8 in 35.3% of cases (n=6), the score was found to be higher than 8 in 64.7% of them (n=11). Median heart rate in patients with PTS <=8 was 94 beats/min. This value was 70 beats/min in those with PTS >8 (p=0.007). Morbidity rates of PTS <=8 cases and PTS >8 cases were 29.4% and 5.9%, respectively (p=0.026). While LHS was 22.8 days in PTS <=8 cases, LHS was found to be only 4 days in PTS >8 cases. This difference was found to be statistically significant (p=0.001). CONCLUSION: PTS is very efficient and a time-saving procedure to assess the severity of trauma caused by the shrapnel effect. The median heart rate, morbidity, and LHS increased significantly in patients with PTS <=8.

    ABSTRACT: BACKGROUND AND AIMS: Caustic esophageal injury is a rare clinical condition in adult patients. Although dilatation, or the conservative approach, is the primary treatment method, some patients require surgical intervention. Because of the rarity of such cases, standard surgical treatment algorithms cannot be utilized. In this article, we present our surgical experience and discuss the challenges in the surgical management of corrosive injury of the esophagus in adults. METHODS: A retrospective review was conducted of 28 patients who suffered from a corrosive esophageal injury between 1996 and 2011. Patient demographics, history of corrosive material ingestion, preoperative findings, treatment strategy, operative technique, postoperative course, requirements for further treatment, and the current status of the patients were investigated. RESULTS: All patients underwent a transhiatal esophagectomy in addition to a gastric pull-up with a cervical esophagogastrostomy. The mean follow-up time was 62 (12-140) months. One patient developed a deep surgical infection; anastomotic stenosis was noted and treated with dilatation in 13 patients. The mean time period between the operation and the first dilatation for 12 patients was 81 (45-161) days. The mean dilatation count for the patients was 3 (1-10). CONCLUSION: Although it comes with high anastomotic stenosis rates, transhiatal esophagectomy and gastric pull-up with cervical anastomosis is a safe procedure, which can be performed for the treatment of corrosive esophageal stricture.

    ABSTRACT: Many materials are currently being used to reinforce the crural repair. Perforation, intensive fibrosis, and price are limiting the usage of these materials. Our purpose was to seek an alternative, cheap, always available, and inert material to use for cruroplasty reinforcement. Twenty-four patients participated and were randomly divided into 2 groups (graft+laparoscopic Nissen fundoplication and laparoscopic Nissen fundoplication alone) with 12 patients in each group. Total operation time, postoperative dysphagia rate, dysphagia improvement time, postoperative pain, recurrence, and incisional hernia rate were compared. There was no difference in terms of study parameters between both groups except for the mean operation time. Autograft hiatoplasty seems to be a good alternative for crural reinforcement. It provides safe reinforcement, has the same dysphagia rates as meshless hiatoplasty, and avoids potential complications of redo surgery by minimizing extensive fibrosis. Furthermore, the rectus abdominus sheath is always available and inexpensive.

    ABSTRACT: Ureteral stents are used to reduce urologic complications after renal transplantation. However, they predispose to infection. The optimal time to keep them in the urinary tract has not yet been defined. The aim of this study was to evaluate the effect of early removal at the end of 2 weeks on urinary tract infections and early urologic complications (within 3 months), such as ureteroneocyctostomy leakage as well as ureteral anastomosis stricture or obstruction. We retrospectively analyzed the medical records of 48 patients who underwent renal transplantation using a ureteral stent. The patients were divided into two groups according to the time of stent removal: at the end of 2 weeks (group A; n = 10) versus at a later time (group B; n = 38). The urologic complication rate was 0% in group A and the urinary tract infection rate, 2%. The urologic complication rate was 0% in group B and the urinary tract infection rate, 35%. Early removal of the stent at the end of 2 weeks after renal transplantation is decreased the rate of urinary tract infections.

    ABSTRACT: De Garengeot's hernia is a rare condition of acute appendicitis in an incarcerated femoral hernia. A 65-year-old woman was admitted to the emergency room with a 3-day history of a painful and non-reducible mass in her right groin. The patient underwent emergency surgery. At exploration, an acute appendicitis in an incarcerated femoral hernia was identified, likely prediagnosed by computed tomography. The postoperative period was uneventful. In De Garengeot's hernia, early diagnosis is important to reduce the morbidity rate. The surgical approach should be designed according to the condition of the patient, the anatomical position of the appendix vermiformis, and the likelihood of complications.

    ABSTRACT: Oxygen radicals and radicals derived from nitrogen metabolism are important in wound and anostomotic healing. In particular, nitrous oxide, originating from induced nitrous oxide synthetase, retards the wound healing process by producing peroxynitride. Therefore induced nitric oxide synthase (INOS) inhibitors and peroxynitride cleansing agents seem helpful in promoting healing. The purpose of this study was to investigate the effects of N-acetylcysteine (antioxidant), ebselen (peroxynitride cleansing agent) and 1400w (INOS inhibitor) on experimental colonic anastomotic wound healing. 45 randomized Sprague-Dawley rats received colonic anastomosis, and all animals were treated for four days with drugs specific for each group except for the sham and control groups. All rats were given a relaparatomy on the fifth day of the study and evaluated for study parameters indicating anastomotic healing, burst pressure, tissue malondialdehit (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx) and hydroxyproline (OH-proline). when compared to the control group, increased (p < 0.01) burst pressure, OH-proline and decreased MDA, and SOD levels were noted in the 1400w group. Furthermore, the GPx levels were higher (p < 0.05) in rats given NAC therapy. the positive results of selective INOS inhibition using 1400w in this study confirm the adverse effects of the INOS enzyme on anastomotic wound healing. Therefore, we have concluded that 1400w may be helpful in promoting anastomotic healing.

    ABSTRACT: The increase in terrorist attacks has brought a profound and new knowledge of blast injuries. In order to improve our knowledge regarding the mechanisms of blast injuries, we analyzed the effects of shock waves. 100 g TNT and 1000 g C4 were detonated and recorded by high-speed camera. Blast wind, shock wave and shrapnel speeds were calculated, and final condition of the target was examined. A flash ball appeared first followed by the shock wave. Finally, blast wind occurred and shrapnel was distributed. The macroscopic structure of targets was not affected by the shock wave but was affected by shrapnel and blast wind. Shock waves created a transparent ballistic gel inside the target mat by changing its microscopic structure. The speed of the shock wave was 6482-7194 m/sn and shrapnel speed was 1420-1752 m/sn. Shock waves especially affect the air-filled organs and cause lung injury, acute respiratory distress syndrome, and intestinal and eardrum perforation. Blast wind destroys targets due to its high speed and high density. The main cause of mortality is shrapnel injury. The high temperature created by the explosion causes thermal injuries. Being informed of the mechanisms of blast injuries will assist in providing better treatment. Additionally, consideration of all mechanisms of blast injuries will facilitate lower mortality and morbidity rates.

    ABSTRACT: Acute appendicitis is one of the most common surgical emergencies. Diagnosis is usually made depending on the presenting history, clinical evaluation, and laboratory tests. The aim of this study was to investigate the role of urinary 5-hydroxyindoleacetic acid (U-5-HIAA) in the early diagnosis of acute appendicitis. Thirty-five pigmented male rabbits were divided into 5 groups. Group 1 is the control (n = 7); group 2 is the sham (n = 10). The appendix was ligated from its base, and an appendectomy was performed after 12, 24, 36 hours in group 3 (n = 7), group 4 (n = 7), and group 5 (n = 7), respectively. Spot urine samples were obtained for U-5-HIAA determination, and appendectomy tissues were examined histopathologically. Acute appendicitis was diagnosed in all animals in group 3, group 4, and group 5, and the mean levels of U-5-HIAA in group 3 were higher than in the other groups. The mean of U-5-HIAA levels between animals with appendicitis and those without showed a significant difference (P = .003). The U-5-HIAA cutoff point of 4.15 mg/g creatinine had a sensitivity of 85%, a specificity of 64.29%, and an accuracy of 76% (area under curve = 0.805) for acute appendicitis. The probability of acute appendicitis is found to be 10, 2 times more when the U-5-HIAA level is greater than 4.15 mg/g creatinine. We have concluded that spot U-5-HIAA level increases significantly in the early stages of acute appendicitis.

    ABSTRACT: The aim of the study is to evaluate the analgesic efficiency of perioperative magnesium sulphate infusion in patients undergoing laparoscopic cholecystectomy (LC). In a randomized, double-blind trial study, 83 patients were divided into two groups. Group MT received 50 mg/kg i.v. magnesium sulphate in 100 ml of 0.9% normal saline and Group T received the same volume of isotonic saline during the intraoperative period. The cumulative post-operative tramadol consumption was measured to assess the analgesic effect using a patient-controlled analgesia device. Pain intensities at rest and while coughing were evaluated at 0, 2, 4, 8, 12, and 24 h post-operatively. The pain scores in Group MT were significantly lower than Group T at 0, 4, and 12 h post-operatively. The average of visual analogue scale at rest and during cough during 24 h post-operatively was found to be statistically significant between groups. The total dose of tramadol the 24-h period in Group MT and Group T was found to be 281.34 +/- 90.82 and 317.46 +/- 129.59, respectively. Per-operative 50 mg/kg magnesium sulphate infusion is effective in reducing post-operative pain in patients undergoing LC.

    ABSTRACT: To evaluate the pain level, analgesic consumption, operation time, bleeding and early complications after open and closed hemorrhoidectomy using a harmonic scalpel (HS) and classical methods. Between January 2005 and January 2006, 87 patients with grade III-IV hemorrhoids, admitted in General Surgery Clinic, Gulhane Military Medical Academy, Ankara, Turkey were enrolled in the study. They were randomized into open HS (n=22), closed HS (n=22), Miligan Morgan (n=22), and Ferguson (n=21) hemorrhoidectomy. Patients were evaluated for postoperative pain, painkiller consumption, bleeding and operation time. Bleeding volume was significantly lower in Groups I-II (p<0.001). Operation time was significantly shorter in Group I (p<0.001). Postoperative pain and pain at the time of first defecation, was significantly lower in Groups I-III (p<0.001) compared with the other 2 groups and lower during days 2-6 in Group I compared to the Group III (p<0.004). Visual Analogue Scale results were similar in Groups II and IV. Analgesic consumption in Groups I-III was significantly lower than Groups II-IV (p<0.001). Oral analgesic consumption during 2-5 postoperative days was lower in Group I than in Group III (p<0.007) and similar in closed hemorrhoidectomy group. The use of HS in hemorrhoidectomy reduces postoperative pain, analgesic consumption, operation time, and bleeding. Harmonic scalpel hemorrhoidectomy is an effective, comfortable, and safe procedure. Use of suture in hemorrhoidectomy is a major cause of postoperative pain.

    ABSTRACT: Diaphragmatic rupture occurs in 0.8% to 3.6% of patients after blunt or penetrating thoracoabdominal trauma, and the preoperative diagnosis is difficult. The diagnosis of traumatic diaphragmatic rupture may be made on initial presentation or at any time later. Right-sided diaphragmatic rupture is rare and occurs in approximately 5% to 20% of all diaphragmatic disruptions. The incidence of herniation of the intra-abdominal organs into the pleural cavity is also low, observed in only about 19% of right-sided diaphragmatic ruptures. We present a case of right-sided traumatic rupture of the diaphragm diagnosed 15 years after the initial blunt trauma. A 22-year-old male patient fell 15 years before and was symptom-free since then. He was referred to our hospital with the signs of herniation of the right diaphragm, which was manifested in the chest x-rays. The definite diagnosis was made through thoracoabdominal computed tomography. The diaphragmatic rupture was repaired via abdominal approach.

    ABSTRACT: To investigate the agreement between esophageal manometry and pH step-up method in two different patient positions. Eighteen subjects were included in the study. First, the distance from the nose to the proximal border of the lower esophageal sphincter (LES) was measured manometrically. Then a different investigator, who was blinded to the results of the first study, measured the same distance using the pH step-up method, with the patient in both upright and supine positions. An assessment of agreement between the two techniques was performed. In the supine position, the measurement of only one subject was outside the range accepted for correct positioning (< or = 3 cm distal or proximal to the LES). In the upright position, errors in measurement were recognized in five subjects. Bland-Altman plots revealed good agreement between measurements obtained manometrically and by the pH-step up method with the patient in the supine position. In the case of nonavailability of manometric detection device, the pH step-up method can facilitate the positioning of the 24 h pH monitoring catheter with the patient in the supine position. This should increase the use of pH-metry in clinical practice for subjects with suspected gastroesophageal reflux disease if our results are supported by further studies.

    ABSTRACT: The effect of ischemia-reperfusion (I/R) injury within a transplanted kidney has not been reported on the liver as a remote organ. One hypothesis is that there is no difference between kidney perfusion solutions regarding antioxidants in liver after an I/R injury. We used four pigs with Ringer's lactate (RL); four with university of Wisconsin (UW); and two in a control (C) group. A liver parenchymal biopsy was obtained before renal artery/vein solution clamping for 20 minutes. Either RL or UW solutions were infused through arterial cannulas for 20 minutes as previously described elsewhere. For the sham group, we used 0.9% NaCl. After reperfusion for 20 minutes, we obtained a second liver parenchymal biopsy. Measurements of superoxide dismutase (SOD), glutathione peroxidase (GP-x), and malondialdehyde (MDA) levels were compared using paired student t tests within groups and analysis of variance between groups. The results were expressed as mean values +/- SEM with P < .05 accepted as significant. Although GP-x, SOD, and MDA decreased after ischemia-perfusion-reperfusion injuries in all groups, except MDA in UW and SOD, and MDA in C groups; only the MDA for C was significant (P = .04) Comparing the groups, GP-x (P = .01) and MDA (P = .003) levels after ischemia-perfusion-reperfusion were significant while changes in SOD levels did not show any difference (P > .05). In a kidney transplantation model, the liver was affected during the ischemia-perfusion-reperfusion process as evidenced by antioxidant enzymes. The pathophysiology and clinical importance of this phenomenon requires further study. Comparing the perfusion solutions, no difference was found between RL and UW regarding their effects to decrease renal I/R injury on the liver in pigs.

    ABSTRACT: Small bowel neoplasms are usually diagnosed when patients are referred with complications such as hemorrhage or obstruction. Intestinal lipomas are the third most frequent benign tumors among all intestinal neoplasms and their definite diagnosis is usually obtained after histopathological examination of the resected specimen. A 76 year-old male patient with partial intestinal obstruction and rectal bleeding at admittance was found to have an abdominal mass on ultrasound. The density pattern of the mass at abdominal CT was supporting a jejunal lipoma leading an intussusception. Then an enteroclysis localized and reduced the jejunojejunal intussusception. The diagnosis of lipoma was confirmed with histopathological examination of the mass removed by an elective intestinal resection. This case was reported as the intestinal lipoma leading a jejunojejunal intussusception associated with bleeding, could be diagnosed preoperatively.

    ABSTRACT: Effects of various types and diameters of guns and related treatment principles are different. Our study was performed to experimentally demonstrate the effects of different gunshots in body tissues. 9x19 mm hand-gun and 7.62x51 mm G-3 infantry rifle were used in the study. Injury models were created through hand-gun and rifle shootings at isolated soft tissue, lower extremity, liver and intestine tissue simulants made of ballistic candle. High-speed cameras were used to capture 1000 frames per second. Images were examined and wound mechanisms were evaluated. It was observed that the colon content distributed more within the surrounding tissues by the rifle shootings comparing with hand-gun shootings and could be an infection source due to the large size of the cavity in the colon. Especially when the bullets hitting the bone were investigated, it was seen that much more tissue injury occurs with high speed bullets due to bullet deformation and fragmentation. However, no significant difference was found between the effect of hand-gun and rifle bullets passing through the extremity without hitting the bone. To know the type of the gun that caused the injury and its characteristics will allow to estimate severity and size of the injury before the treatment and to focus on different alternatives of treatment. Therefore, use of appropriate models is required in experimental studies.

    ABSTRACT: Stump viscera caused by an incomplete operation can present the same symptoms as before the first operation. Furthermore, as an acute clinical event, these incomplete resections may sometimes cause acute abdomen and may need emergency surgical intervention. A 34-year-old woman with a history of laparoscopic cholecystectomy 5 days before was admitted with acute abdominal symptoms. Abdominal exploration revealed that she had undergone incomplete resection of the gallbladder. Another patient, a 21-year-old man, was admitted with complaints of fluid drainage from his appendectomy incision scar. He was diagnosed as having enterocutaneous fistula. Abdominal exploration revealed a stump appendix fistulizing to the abdominal wall. The third patient was a 32-year-old man with an appendectomy scar who was admitted with complaints of acute appendicitis. The patient was diagnosed as having acute appendicitis and underwent an appendectomy. A stump appendix was removed during the operation. Surgeons should be aware of stump pathologies and keep in mind a possible incomplete operation to prevent delayed diagnosis and treatment.
