RESUMO
Background: We discuss the role of Laboratory Risk Indicator for the Necrotizing Fasciitis (LRINEC) on the prognosis of this disease. Necrotizing Fasciitis (NF) is characterised by rapid spreading of infection and necrosis of the soft tissues and fascia. Methods: Thirty patients (17 male, 13 female, mean age 57.5 years) were treated between 2011- 2016 (in our center); they were analysed retrospectively regarding age, sex, isolated microbiological agents, modalities of treatment and mortality rate. Results: The majority of the infections were detected in the perineum (14 patients). Other sites of infection were: the presacral region (3 patients), as well as abdominal region after elective (10 patients) and emergency surgery (2 patients), respectively. 53.3% of patients had at least one predisposing comorbid factor such as diabetes mellitus, hypertension, cardiomyopathy and congestive heart failure. The tissue cultures were positive in 12 patients. Mean LRINEC score on admission was 8.5 +-2.85. There was a strong correlation between LRINEC score and patient age (p=0.018, R=0.43). LRINEC score was affected by neither gender nor the presence of any comorbidities. The patients were classified according to Wang and Wong staging system, as follows: one patient in stage 1, 15 patients in stage 2 and 14 patients in stage 3. Patients with higher Wang and Wong stages had significantly higher LRINEC scores. The mortality rate was 16.7%. The mean LRINEC score of deceased patients compared to patients who were successfully treated was 9.2ÃÂ+-2.2 and 8.36ÃÂ+-2.9. Conclusion: Even though LRINEC score and Wang and Wong stage were significatly related with ICU stay, their direct effect on mortality wasn't significant in our study.

OBJECTIVE: Polypropylene meshes are one of the most frequently used patches in inguinal hernia repairs. This material was proved to be not completely inert, and may cause inflammatory responses like foreign body reactions. One of the physical results of these inflammatory reactions against the mesh is mesh shrinkage which is responsible for recurrence and pain. In this study, we aimed to investigate the effects of the suture technique on mesh shrinkage. METHODS: 36 animals were used for the study. Subjects were divided into 3 groups. In the first group the mesh (onlay) was not fixated by any means. In the second group, mesh was placed on the abdomen wall, after which the mesh was fixated with interrupted suturing. In the third group, continuous suturing was applied after the placement of the mesh. Mesh shrinkage was measured macroscopically, and the mesh site reaction was evaluated microscopically. At the end of the second month, 18 subjects were sacrificed again to conduct the same procedure. RESULTS AND CONCLUSION: When meshes are used for hernia repairs, shrinkage may be observed in meshes placed on fascia. In the first group without mesh fixation, mesh shrinkage was more significant in the second month compared to the first month. The amount of shrinkage of without fixation group was found to significantly differ during the second month from interrupted and continuous suture groups. Even though statistically not significant, fixation of the mesh with interrupted sutures seems to be more advantageous compared to fixation with continuous sutures.

OBJECTIVE: Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors that express type 3 tyrosine kinase receptors and are thought to develop from the neoplastic transformation of the interstitial Cajal cells. The present study was performed to morphologically and immunohistologically evaluate GISTs, to compare their qualities using a GIST risk categorization system, and to identify the diagnostic and prognostic parameters of GISTs. MATERIAL AND METHODS: A total of 27 patients with GISTs underwent treatment and were followed up at the Gaziosmanpasa Taksim Training and Research Hospital. Descriptive statistics was used to calculate the mean and median values. Survival analysis was performed by the Kaplan-Meier method. The analyses were performed using the SPSS version 22.0 software. RESULTS: The mean follow-up time was 3.5 (5 months to 13 years) years. The mean age was 60.4 (29-82) years. The tumors were localized in the stomach (62.9%), extraintestinal areas (14.8%), intestine (7.4%), esophagus (7.4%), and rectum (7.4%). Twenty-four patients were classified according to the Fletcher system. Of these patients, 7 (25.9%) were classified as very low risk, 8 (29.6%) as low risk, 7 (25.9%) as intermediate risk, and 2 (7.4%) as high risk. Twenty-four patients underwent surgery. Of the 3 patients who did not undergo surgery, 1 had metastatic disease at the time of diagnosis, and 2 had mini- or micro-GISTs in the stomach. On endoscopic surveillance, all tumors remained stable. Three out of the 27 patients were lost to follow-up. Two patients developed recurrence, and 1 patient died of GIST. CONCLUSION: We analyzed the clinical and pathological characteristics of GIST. The most common site of tumor origin was the stomach. The size, mitotic index, and Ki-67 values were to be found high in intermediate- and high-risk groups and metastatic diseases.
RESUMO
Choledochoduodenal fistula (CDF) is an abnormal passage between the choledochus and duodenum. The most common causes of CDF are cholelithiasis, duodenal ulcer, and tumors. There are mainly two types of fistulas depending on the location. Type 1 is usually present on the longitudinal fold just close to the papilla. Type 2 is present at the duodenal mucosa adjacent to the longitudinal fold and probably caused by larger stones, duodenal ulcer penetration, impacted cystic duct stones, and as a complication of laparoscopic cholecystectomy. In this study, we investigate the characteristics of our patients those were diagnosed with CDF. This is a descriptive study. We retrospectively obtained the data of 21 patients with spontaneous CDF out of 2430 endoscopic retrograde cholangiopancreaticography (ERCP) patients between 2000 and 2014. We analyzed the laboratory results, demographic and etiological features, major clinical presentations, diagnostic methods, and treatment modalities of the patients. The mean age of the 21 patients was 66.6 ± 2.2 years and a female to male ratio was 12:9. In ten patients, interventional procedures were performed via fistulotomy, not through the papilla. The eventual diagnosis was tumor in five patients and stone or sludge in bile ducts in 14 patients. In the remaining two patients, no reason was found as a cause of CDF. Whipple operation was performed in one patient and stents were placed in three patients for malignacy. Among the 14 patients with sludge or stone in bile ducts, ERCP has been therapeutic in ten. One of the remaining patients has been operated for proximal fistula and underwent choledochus exploration and repair of fistula over a T-tube. In the second patient, stone extraction and T-tube drainage were performed. In patients who had bile duct obstruction and got over of jaundice afterwards, one of the most important reasons of this recovery is the development of spontaneous choledochoduodenal fistula. Even if it is very rare, malignancy can be observed in this area. Therefore, it is extremely important to evaluate the papillary area with ERCP and to conduct biopsy; this will make early diagnosis possible in many patients. In these patients, ERCP can both be diagnostic and therapeutic.
RESUMO
BACKGROUND: The aim of this study was to evaluate the effectiveness of laparostomy with the Bogota bag for the management of patients with severe secondary peritonitis and the risk factors for survival. METHODS: Thirty-seven patients (22 males, 15 females; mean age 63.5; range 44 to 83 years) with secondary peritonitis were treated by laparostomy and temporary closure with Bogota bag. APACHE II scores and Mannheim Peritonitis Index (MPI) were used to calculate the disease severity. The outcomes and effectiveness of APACHE II and MPI values were analyzed retrospectively. RESULTS: The mortality rate was 43.2%. Significant differences were noted between survivors and non-survivors according to initial APACHE II and MPI scores and the number of operations. The non-survivors had higher APACHE II (r=0.81, p=0.001) and MPI (r=0.39, p=0.02) scores. The patients who survived were re-operated 1.6 times and those who died were re-operated 4.7 times. In five patients, laparostomy was closed primarily, while in the others, the wound was left open to heal secondarily. CONCLUSION: Patients with higher APACHE II and MPI scores and number of operations had higher rates of mortality due to their major risk factors. Temporary abdominal closure using the Bogota bag in patients with secondary peritonitis is an inexpensive-simple method, permitting evaluation of underlying viscera and recognition of infection.

BACKGROUND: The objective of our study is to evaluate the preventive effects of selective digestive decontamination (SDD) and mechanical bowel preparation in rats with experimentally induced bacterial translocation. METHODS: Fourty adult male Sprague Dowley rats weighing 250-300 g. were divided equally into four groups as Group 1 (sham [control]), Group 2 (experimentally induced IAH at 19 mmHg), Group 3 ( SDD group) and Group 4 (SDD and mechanical bowel preparation with 19 mmHg intraabdominal pressure). Group 3 and 4 were treated at 12 hours intervals with oral gentamycine 5 mg/kg and IM sefotaxime 100mg/kg Mechanical bowel preparation was performed by oral administration of sodium phosphate. After 24 hours all rats were sacrified; mesenteric lymph nodes, spleen and liver biopsy specimens were harvested aseptically. Specimens were diluted and cultured in McConkey medium and the colony-forming units (CFU/gr ) were calculated. RESULTS: In Kruskal Wallis tests there were no significant differences between Group 1 and 3 or 4, and also Group 3 and 4 (p>0.05, p=0.872 respectively), while differences between Group 1 and 2, and also Group 3 and 4 were statistically significant (p<0.001) with respect to CFU/g estimates. CONCLUSION: These data indicate that selective intestinal decontamination and mechanical bowel preparation prevent bacterial translocation due to intraabdominal hypertension.
