Fixation of the mesh to the abdominal wall has been associated with various postoperative complications for no additional benefit in lowering recurrence rates. For non-recurrent inguinal hernia, non-fixation of the mesh is safe and reliable. Further studies with larger sample sizes are necessary for subgroup analyses.

Cholangitis, with a clinical spectrum between acute ascending cholangitis and acute fulminant cholangitis, the mildest and the most severe forms, respectively, is the infection of bile ducts with a potential of serious mortality and morbidity. Obstruction of the bile ducts followed by infection, with E. coli being the most commonly isolated agent, is common to all forms of cholangitis. Biliary obstruction is caused by choledocholithiasis mostly. “Choledochal pressure” is the most important factor, determining morbidity. If the pressure exceeds 25 cm H2O, which is the critical value, immune dysfunction ensues. Sepsis is common if the infection of biliary ducts is suppurative. Mortality and morbidity are inevitable if left untreated or drained late. The objective of this study is, in the stand point of the current literature, to analyse the diagnostic, therapeutic success and complication rates of ERCP (Endoscopic retrograde cholangiopancreatography) in patients with a diagnosis of acute purulent cholangitis with no response to medical treatment.

We report herein the case of a patient in whom evisceration of the appendix occurred at the site of a drain placed in the right lower quadrant of the abdomen. Because the appendix had become adhered to the side-hole of the drain with an external diameter of 11 mm, it was pulled out attached to the drain. Consequently, the stab wound incision of the drain was extended and an appendectomy was performed under general anesthesia. Thus, drains with a small diameter should be used whenever possible, and side-holes not having any influence on the drainage should be avoided.

Background: This study aimed to evaluate upper gastrointestinal polyps detected during esophagogastroduodenoscopy tests. Materials and Methods: We conducted a retrospective analysis on data regarding 55,987 upper gastrointestinal endoscopy tests performed at the endoscopy unit of Istanbul Education and Research Hospital between January 2006 and June 2012. Results: A total of 66 upper gastrointestinal polyps from 59 patients were analyzed. The most common clinical symptom was dyspepsia, observed in 41 cases (69.5%). The localizations of the polyps were as follows: 29 in the antrum (43.9%), 15 in the corpus (22.7%), 11 in the cardia (16.7%), 3 in the fundus (4.54%), 3 in the second portion of the duodenum (4.54%), 2 in the bulbus (3.03%) and 3 in the lower end of the esophagus (4.54%). Histopathological types of polyps included hyperplastic polyps (44) (66.7%), faveolar hyperplasia ( 8) (12.1%), fundic gland polyps (4) (6.06%), squamous cell polyps (4) (6.06%), hamartomatous polyps (3) (4.54%), and pyloric gland adenoma (3) (4.54%). Histopathological analysis of the gastric mucosa showed chronic atrophic gastritis in 30 cases (50.84%), HP infection in 33 cases (55.9%) and intestinal metaplasia in 19 cases (32.20%). In 3 cases with multiple polyps, adenocarcinoma was detected in hyperplastic polyps. Conclusions: Among polypoid lesions of the upper gastrointestinal tract, the most common histological type is hyperplastic polyps. Generally, HP infection is associated with chronic atrophic gastritis and intestinal metaplasia. The incidence of adenocarcinoma tends to be higher in patients with multiple hyperplastic polyps.

Context:Gallstone disease is one of the most common surgical pathologies. Choledocholithiasis may occur in some of these cases and require surgical intervention. Although there are relatively non-invasive procedures such as endoscopic retrograde cholangiopancreatography (ERCP), this technique is usually unsuccessful in patients with stones larger than 10 mm. In our case, we aimed to report a giant choledochal stone (15 cm × 4.5 cm), which is rare in surgical practice and our treatment with open surgery.Case Report:The patient was a 59-year-old woman. Magnetic resonance cholangiopancreatography (MRCP) had showed a hydropic gallbladder with an excessively dilated CBD and a 110 mm × 41 mm stone. In the operation, an excessively dilated CBD was seen and after choledochotomy and a very large calculus that filled CBD completely. Choledochotomy incision was carried forward and a T-tube choledochostomy with choledochoduodenostomy (CD) was performed. The patient was discharged without any complications on postoperative 8th day.Conclusion:Benign gallstone disease is a multifactorial process, with risk factors such as obesity, hemolytic diseases, diabetes mellitus, and pregnancy. Risk factors for choledocholithiasis are similar to those for gallstone disease. MRCP is a non-invasive technique in detecting choledocholithiasis. The gold standard intervention for CBD stones is ERCP. Stones in CBD may reach very considerable dimensions without causing serious symptoms. The most common symptom is jaundice. During preoperative radiological examination, giant stones may be interfered with malignancies. Surgeons should obey conventional algorithms in diagnosis and open surgery must be kept in mind in earlier stages without being too insistent on endoscopic interventions.

Background. The aim of this study is to discuss the laparoscopic approach and assess the immunohistochemical expression profiles of synaptophysin, Ki-67, and inhibin and patient outcomes in adrenal masses through a series of cases treated at our institution. Method. The study was conducted on 58 patients who were diagnosed with adrenal masses. All cases were operated on laparoscopically for adrenal masses. Results. Both inhibin and synaptophysin were found positive in 45 patients (77,6%). Ki-67 was negative in 11 patients, whereas it was found positive in 42 with a rate of 1%. The size of the masses ranged from 1 up to 9 cm (mean 4,3 ± 1,5). Urine hormone excretion was measured within normal ranges in 47 out of 58 patients (81%). Most of the diagnosed patients were harboring Cortical Adenoma (n: 38; 65,5%). All of the masses were successfully resected without complication except 3 patients. Because of complications of bleeding, the operation was converted to open surgery for 2 patients. Conclusion. Morbidity, mortality, and healing were comparable, regardless of tumor size, yet involvement in both laparoscopic and adrenal surgery was required. Our results suggested that laparoscopic adrenalectomy should replace open surgery as the standard treatment for most adrenal masses.

Objective: Intestinal obstruction due to colorectal tumors requires immediate surgical decompression. Endoscopic stent placement for acute malignant colonic obstruction is gaining widespread acceptance as an alternative to emergency surgery. Our aim in this study was to evaluate the success and complication rates of endoscopic stenting for malignant colonic obstruction. Material and Methods:Patients with acute malignant colonic obstruction who underwent endoscopic stenting between 2011-2014 were retrospectively reviewed. Data included demographic features, localization of obstruction, endoscopic stenting indications, rate of technical and clinical success, complications, morbidity and mortality.Results: Endoscopic stent was successfully placed in 77 out of 82 procedures (93.9%). A colostomy was placed in five cases in which endoscopic stent could not be inserted. There were complications in seven patients with technically successful stents (9.0%). These included three stent migrations, one perforation, and rectal hemorrhage in three patients. There were no stent-related deaths. Conclusion:The mortality rate of emergency surgery for malignant bowel obstruction is relatively high. The use of colonic stents can avoid surgery in patients who are not suitable for emergency surgery and may allow adequate time for preoperative preparation, counseling and staging for those who are suitable for further intervention. We believe that self-expandable metallic stent placement is a safe, effective, and minimal invasive alternative treatment method for malignant colonic obstruction.

Background Incisional hernia is a complication that is encountered with a rate of 2-11 % and can lead to morbidity, work loss, and even mortality. Prosthetic materials that are used in hernia repair are still being tested, and the ideal one has not been proposed yet. While the recurrence rates with primary repair are found to be 30-50 %, these rates are decreased to 0-15 % with mesh repair. These rates emphasize the importance of meshes. The most important criteria in their usage are the advantages and disadvantages of types of meshes. Our aim is to cover the mesh with the subject's own collagen tissue, then to repair the defect with this autogen collagen-covered propylene mesh, and lastly, to prevent or decrease adhesions against the mesh.Methods A total of 14 male, healthy, 250-300 g WistarAlbino rats were included in the study. They were separated into two equal groups as Group A (control group) and Group B (study group). In Group A, full-thickness defects were repaired with polypropylene meshes. In Group B, meshes of the same size were placed under the skins of the rats and excised on the ninth day. After creating a full-thickness defect, it was repaired with the rat's own mesh. On the 21st day, in both groups, the adhesions between intra-abdominal organs and the mesh were evaluated by two independent observers according to adhesion scoring system. The groups were compared in means of fibrosis and inflammation scores. The pathologist was not informed about which preparate belonged to which group.Results In Group A, adhesion area, adhesion strength, inflammation, collagen tissue, and fibroblast activity were significantly higher than Group B.Conclusions According to our results, after in-lay placement of autogen tissue-covered polypropylene meshes, adhesions can decrease and complications due to intra-abdominal adhesions can be prevented, and relatively low costs may contribute to health expenditure.
