    Abstract Objective: To compare postoperative morbidity and mortality results in patients with and without endoscopic and percutaneous transhepatic biliary drainage due to obstructive jaundice caused by a periampullary tumor and to examine the effect of intervals until surgery on postoperative morbidity and mortality in patients who underwent preoperative biliary drainage (BD).
    Methods: Patients were divided into 3 groups according to their BD status. Group1, no biliary drainage (NBD), Group2, Endoscopic biliary drainage (EBD), Group3, Percutaneous transhepatic biliary drainage (PBD). Patients who underwent biliary drainage before pancreaticoduodenectomy (PD) were divided into 3 intervals according to the time interval between drainage and surgery: Short interval; patients undergoing surgery in 21 days and <, Medium interval; between 22-42 days, Long interval; 43 days and >. Groups and intervals were compared in terms of postoperative morbidity and mortality.
    Results: Of the 122 patients who underwent PD, 76 (62.3%) were male, and 46 (37.7%) were female. Within these patients, 47 (38.52%) had NPD, 42 (34.42%) had EBD, and 33 (27.05%) had PBD. The rate of postoperative Grade B and C fistula was higher in the groups that underwent preoperative drainage compared to the group without preoperative drainage (p = 0.007).
    Conclusion: It was determined that the postoperative complication rate was lower in patients who did not undergo BD compared to patients who underwent biliary drainage. Besides, the endoscopic drainage method was observed to be associated with fewer complications than the percutaneous transhepatic drainage method.
    Key words: Preoperative biliary drainage, Pancreaticoduodenectomy, Periampullary tumors, Post procedure complication, Timing.

    Abstract Background: In colorectal cancer (CRC), the mutation of the K(N)RAS gene has a significant impact on the clinical course, and is associated with a negative prognosis. We aim to present the morbidity and long-term results in patients with wild/mut-K(N)RAS, undergoing CRC surgery.
    Methods: A total of 116 patients who underwent surgery for colorectal cancers with wild/mut-K(N)RAS were included in this retrospective study. The patients were divided into two groups: wild-K(N)RAS patients (Group 1) and mutant- K(N)RAS patients (Group 2). Results were evaluated for clinical, operative, morbidity and long-term survival outcomes.
    Materials and methods: The highest surgical site infection (SSI) rate (OR=140.339)(4.303-4581.307)(P=0.005) was seen in patients given Bevacizumab during neoadjuvant treatment. Meanwhile, the SSI site infection rate was at its lowest in cases where minimally invasive surgery was preferred (OR=0.062)(0.006-0.628)(P=0.019). In addition, the overall median survival rate for the total cohort was 38±3.1 (31-44) months. Multivariate analysis showed that CEA (>5ng/mL)(HR 2.94)(1.337-6.492))(P=0.007); tumor stage (P=0.034), T(T4) stage (HR 1.91)(1.605-252.6)(P=0.02); metastasectomy/ablation (HR 0.19)(0.077-0.520)(P=0.001); the number of removed metastatic lymph nodes (HR 1.08)(1.010-1.155)(P=0.025); tumor implant or nodule (HR 2.71)(1.102-6.706)(P=0.03); curative resection (HR 2.40)(0.878-6.580)(P=0.042) to be factors affecting the overall survival rate.
    Conclusion: Treatment with Bevacizumab during the neoadjuvant period in mut-K(N)RAS cases, surgical technique and complications of Grade 3 or higher are risk factors for SSI on morbidity in patients with mut/wild-K(N)RAS undergoing colorectal cancer surgery. Moreover, CEA (>5ng/mL), tumor stage, T stage, metastasectomy/ablation, the number of removed metastatic lymph nodes, tumor implant/nodule and curative resection are risk factors on the overall survival rate.

    Abstract Aim: This paper investigates the risk factors preventing the reversal and nonreversal of Hartmann's procedure, as a surgical technique that has been performed in our clinic for ten years.
    Methods: The study involved a ten-year Hartmann's procedure followed up at our center. The patients were divided into Hartmann reversal and nonreversal groups. Groups were examined in terms of age, gender, diagnosis, stage of malignancy, ASA score, comorbidity, perioperative morbidity-mortality, and the length of the operation.
    Results: Age (
    Conclusion: Although Hartmann's procedure is performed in emergency surgery, the nonreversal of the colostomy is a problem in itself. It should be kept in mind that patients who have high risks are likely to have a permanent stoma.

    Abstract Objectives: Minimal invasive surgery is one of the most popular treatment approaches which is safe and effective in experienced hands in different clinical practices. In the present study, we aimed to evaluate the risks factors for conversion to open splenectomy and the performance of indirect hilum dissection technique.
    Material and methods: A total of 56 patients who underwent laparoscopic or robotic splenectomy for isolated spleen diseases were included into the study. Patients were divided into two groups as robotic or laparoscopic splenectomy (Group 1; n= 48) and conversion to open surgery (Group 2; n= 8). Patients were retrospectively evaluated according to clinical, biochemical, hematological and microbiological parameters and morbidity.
    Results: No statistically significant difference was found between the groups in terms of age, gender, body mass index (BMI), ASA score, co-morbid disease, operation time, hospital stay, follow-up period, accessory spleen, diagnosis, international normalized ratio (INR), red cell distribution width (RDW), platelet distribution width (PDW), platelet to lymphocyte ratio (PLR), neutrophil to lymphocyte ratio (NLR), reapplication, splenosis, surgical site infection, vascular thrombus and incisional hernia (p> 0.05). On the other hand, intraoperative splenic hilum hemorrhage and increased spleen size (p <0.05) were higher in the conversion to open surgery group. In logistic regression analysis, intraoperative splenic hilum hemorrhage (B= 4.127) (OR= 61.974) (95% CI= 3.913-981.454) (p= 0.003) and increased spleen volume (B= 3.114) (OR= 22.509) (95% CI= 1.818-278.714) (p= 0.015) were found as risk factors for conversion to open surgery.
    Conclusion: Intraoperative hemorrhage from the splenic hilum and increased spleen volume (> 400 cm3) are risk factors for conversion to open splenectomy in patients undergoing elective robotic or laparoscopic splenectomy. Indirect splenic hilum dissection can decrease intraoperative hemorrhage and conversion to open surgery.

    Abstract Purpose: Bowel wall thickening (BWT) is a common finding in abdominal computerized tomography imaging (CTi). The purpose of the present study was a prospective assessment and management of patients who have BWT in abdominal CTi.
    Materials and methods: This study was conducted between January 2012 and July 2014 at Erzincan University Hospital, Turkey, with 64 patients who were admitted to the emergency and general surgery department. All of the patients had received colonoscopies due to BWT seen in abdominal CTi.
    Results: Twenty-three (36%) female and 41 (64%) male patients were included in the study. The mean age was 56.2 years (range, 14 to 84 y). The positive predictive value of CTi for BWT was 87.5%. The positive predictive value of a CTi diagnosis of the disease according to a radiologist's report was 78.1%. Common pathologies detected by colonoscopy included neoplasia and inflammatory bowel disease.
    Conclusions: Diagnosis of BWT by abdominal CTi reveals pathologies in many cases. Colonoscopies will be helpful in the differential diagnosis.

    Abstract Objective: To compare Ligation under Vision (LUV) with Ferguson Hemorrhoidectomy (FH) in patients with Grade II, III and IV hemorrhoidal diseases according to their postoperative outcomes.
    Methods: Between July 2008 and August 2014, 155 patients underwent FH and 120 patients LUV, in Sakarya University Teaching and Research Hospital. Our retrospective analysis focuses on postoperative complications, postoperative pain and rate of recurrence. In LUV procedure, submucosal tissue of the hemorrhoidal pile base was transfixed using absorbable sutures under direct vision through anoscope in the Jackknife position.
    Results: In a mean postoperative follow-up period of 51.76+/-22.3 months; ectropion, anal fissure, and anal incontinence were the most frequent complications. The overall complication rate was significantly less after LUV than FH, (6.7%
    Conclusions: LUV is a safe, and practical procedure with similar outcomes compared to FH. LUV may be a better choice than excisional hemorrhoidectomies when three or four quadrants of the anal canal are involved with hemorrhoids as this reduces mucosal defect related possible complications such as ectropion and anal stenosis.

    Abstract Introduction: Thyroid nodules are commonly seen. Our aim is to learn the behaviors and operational attitudes of surgeons approaching the thyroid nodules. In a literature search, our study is the first and only study performed merely on surgeons.
    Materials- metods: This cross-sectional study was done between June 2014-January 2015. The questionnaire consists of 25 questions. Initially, general questions consisting of demographic findings were asked. In step 2, questions consisting of the index case and case variants were asked. Results were compared with American Thyroid Association, European Thyroid Association guidelines, and Australia survey results. In the last step, questions about thyroid operations were asked.
    Results: A total of 301 surgeons responded to the survey. The response rate was approximately 20%. Thirty nine were female and 262 were male. For the question that asks the diameter of the thyroid nodule that will require a thyroid fine needle aspiration biopsy (TFNAB), 47.5% of the surgeons will require a TFNAB for 1-2 cm solid nodules. 40.15% of the surgeons required a TFNAB regardless of size. 46.1% of the surgeons who required a TFNAB between 1 and 2 cm solid nodules also required scintigraphy at diagnosis of suppressed TSH case variant.
    Conclusion: In this survey, we identified differences from up-to-date guidelines about approaching thyroid nodules and perioperative thyroid surgery. From our perspective, surgeons need updated training requirements. This can be done with updated seminars across the country. Thereby approaches may become standard and consequently patients may have qualified services.

    Abstract Strongyloidiasis is a parasitosis caused by the female nematode of the Strongyloides stercoralis. S. stercoralis causes a chronic infection that is asymptomatic in 50% of chronically infected patients, and it can also affect the stomach. Gastric involvement causes symptoms mostly mimicking gastritis. We report herein a case of gastric perforation in a 37-year-old woman, which was thought to be caused by S. stercoralis.

    Abstract Objective: Benign nodular goiter (BNG) can cause narrowing of the upper airway. In some rare cases, obstruction of the upper airway also occurs. The following paper reports our experiences with regard to BNG patients who experienced obstruction of the upper airway.
    Materials and methods: We retrospectively investigated the records of 13 patients with acute airway obstruction due to BNG who were admitted to the General Surgery Department of Ataturk University Medical School between January 2000 and December 2007.
    Results: Thirteen patients with airway obstruction secondary to BNG were hospitalized during this period. There were two males and 11 females, and the mean age was 58.5 years (range 37-74 years). For all patients, the primary symptom upon admission was defined as respiratory distress; all patients had varying degrees of respiratory distress upon admission. Three of the patients underwent emergent endotracheal intubation in the emergency room. A preoperative radiological evaluation was performed with thyroid ultrasonography (US) and computed tomography (CT). There were retrosternal or substernal components of the BNG in nine patients. Twelve patients underwent operations, while one patient with mild respiratory distress elected not to be operated on. Ten patients underwent total thyroidectomies, while two patients underwent near-total thyroidectomies. One patient with retrosternal goiter also underwent a median sternotomy. Three patients received a tracheostomy after the operation. Suction drains were utilized in all operations. During the post-operative period, two patients suffered from voice impairment, and seven patients experienced hypocalcemia. Two patients died. Pathological examination of the thyroidectomy tissue revealed BNG in all cases. In addition, two patients had micropapillary carcinomas.
    Conclusion: Although BNG causing upper airway obstruction is rare, it is an important clinical entity because of the need for emergent operation, the increased rate of complications, and high mortality.
