Effect of preoperative anxiety level on postoperative pain, analgesic consumption in patients undergoing laparoscopic sleeve gastrectomy: an observational cohort study.

BACKGRAUND: This prospective observational cohort study aimed to investigate the relationship between preoperative anxiety levels and postoperative pain and analgesic requirement in patients undergoing laparoscopic sleeve gastrectomy. METHODS: Forty two female patients with body mass index ≥ 35, who underwent laparoscopic sleeve gastrectomy for treatment of obesity were included in the study. Spielberger's state and trait anxiety scales were used in this study. Demographic data of the patients, anesthetic and analgesic drugs during the surgery, pain levels measured with verbal analog scale at the postoperative 1st, 4th, 12th, and 24th hour, sedation levels measured with the Ramsay sedation scale, and the amount of analgesic consumed were recorded. Anesthesiologist, surgeon, and patient were not informed of the anxiety level results. The relationship between preoperative anxiety and postoperative pain and analgesic consumption was evaluated by Spearman's correlation analysis. Stepwise multiple linear regression analysis was applied. Normal Distribution control was performed by applying the Shapiro-Wilk test to residual values ​​obtained from the final model. RESULTS: There was no relationship between trait anxiety level and postoperative pain and analgesic consumption. A correlation was found between state anxiety level and pain level up to 24 hours and analgesic consumption (p < 0.05). According to the obtained model it had been observed that the university graduates consumed more analgesic compared to other education level groups. CONCLUSION: In this study, a relationship was found between preoperative state anxiety level and 24-hour pain scores and analgesic consumption in patients who underwent laparoscopic sleeve gastrectomy under general anesthesia.

Optimization of change in epicardial fat thickness for obese patients who lost weight via the bariatric surgery method using central composite and Box-Behnken experimental designs.

BACKGROUND: The aim of this study was to detect the optimal values for Age, Body Mass Index (BMI) and HOMA-IR of obese patients prior to surgery that results in a maximal decrease of visceral fat mass 6 months after bariatric surgery. METHOD: In this study, 33 experimental set-ups were designed. This study was approved by Baskent University Medical and Health Sciences Research Board (Approval number: KA16/281). The study data consisted of 40 obese patients who lost weight through the bariatric surgery between February 2015 and December 2016. The values of BMI, Age and HOMA for the obese patients who lost weight through the bariatric surgery were evaluated in three categories and at three levels; the response variable was determined as the Change in Epicardial Fat Thickness (ΔEFT). RESULTS: As a result of CCD analysis, the optimum ΔEFT = 2.571 was determined when Age = 30.52, BMI = 45.30, and HOMA = 34.62. As a result of the BBD analysis, the optimum ΔEFT = 3.756 was determined, when Age = 38.36, BMI = 63.18, and HOMA = 14.95. The optimum ΔEFT was modeled with Contour and Response Surface plots. CONCLUSION: Based on the two surface response models used in our study, the maximal decrease of visceral fat mass as assessed by measuring echography images of epicardial fat thickness can be obtained by bariatric surgery of persons who are between 31 and 38 year old, have a BMI between 45 and 63 kg/m2 and have a HOMA-IR 34 between 15 and 35. Central Composite Design and a Box-Behnken Design of suitable patient data predicted 35 optimal settings of independent variables for the maximal clinical response of an intervention.

Recommendations for bariatric and metabolic surgical operations during the COVID-19 pandemic in Turkey.

The world has been struggling with the COVID-19 virus since December 2019. Turkey has also been battling with the virus since March 2019. While struggling with this unknown virus, we have postponed our new bariatric surgeries like most elective surgery. However, curfew and quarantine period (increase in food intake and decreased physical activity) increases risks for morbidity and mortality because of obesity and diabetes. When the pandemic decreases and disappears, many obesity patients will seek treatment for obesity and the workload of surgeons will increase. Before bariatric and metabolic surgery operations, which is the most effective treatment of obesity and related comorbidities, necessary precautions must be determined and implemented to protect patients and healthcare workers before and during surgery. In this review, it was aimed to determine the pre-peri and postoperative periods of bariatric surgical requirements. This review has been written on behalf of the Turkish Society for Metabolic and Bariatric Surgery as an initiative in order to answer some questions about bariatric and metabolic surgery during the COVID-19 pandemic.

Assessment of Carotid Artery Distensibility and Elasticity After Laparoscopic Sleeve Gastrectomy: a Prospective Study.

PURPOSE: Although it is well known that obesity increases the risk of atherosclerosis in carotid arteries, it is not clear whether this risk changes after obesity surgery. The aim of this study was to investigate whether weight reduction with a laparoscopic sleeve gastrectomy (LSG) has any effect on distensibility and elasticity which show subclinical atherosclerosis in the carotid arteries of obese individuals. MATERIALS AND METHODS: This prospective study included 130 patients (body mass index (BMI) 48.21 ± 6.97 kg/m2) who underwent LSG. The patients were followed up for 1 year. Comparisons were made of the distensibiliy and elasticity values calculated preoperatively and at 1, 3, 6, and 12 months, postoperatively. RESULTS: There was a statistically significant increase in distensibility and elasticity values from baseline to 1, 3, 6, and 12 months postoperatively (p < 0.001 for both comparisons). The multiple linear regression analysis was used to find the variables affecting both distensibility and elasticity. According to the results, the presence of BMI decreases distensibility percentage change level by 0.38 units (ß= - 0.38, 95% CI - 0.51;- 0.25, p < 0.001). The presence of fasting plasma glucose decreases elasticity percentage change level by 0.20 units. (ß= - 0.20, 95% CI - 0.39; - 0.01, p = 0.037). CONCLUSION: Carotid artery distensibility and elasticity values increase after LSG, and this change could be caused by the change in metabolic parameters and heart geometry. These results may indirectly suggest that subclinical atherosclerosis in carotid arteries has decreased after obesity surgery.

Intraoperative neuromonitoring of the RLNs during TOETVA procedures.

Transoral endoscopic thyroidectomy by vestibular approach (TOETVA) is now being performed in increasing frequency and getting more and more attention. TOETVA is carried out through three incisions in the oral vestibular area. Thyroidectomy is performed endoscopically using conventional laparoscopic instruments, an energy based device and neuromonitoring instruments. Intraoperative neuromonitoring is one of the tools of utmost importance, used for navigation and confirmation of the functional integrity of the recurrent nerve during TOETVA. The aim of this study is to give information about the standards and technique of intraoperative neuromonitoring of the recurrent laryngeal nerves during TOETVA procedures. TOETVA is a safe technique with no visible scarring and hence resulting in an excellent cosmetic effect. We believe that neuromonitoring of the recurrent laryngeal nerves also minimizes the risk of nerve damage and is an essential safety component in this technique.

Robotic adrenalectomy.

With the recent advances in equipment and surgical techniques, robot-assisted surgery has become accepted and efficient in the surgical field. It is an emerging technology that can safely be applied for a broad spectrum of surgical procedures. As a result of increased ergonomics, three-dimensional view of the operative area and improved moving capacity of the robotic arms with multi-articulation, robotic technology also has found place in adrenal surgery. Recently, robot-assisted adrenal surgery has been adopted widely in many high-volume tertiary centers. Although there are expected theoretical benefits to this approach, the literature is lacking regarding high level evidence. In this review, we will discuss implementation of robotic adrenalectomy as well as perioperative and postoperative measures that helped improved outcomes, offer a comparison of outcomes between conventional laparoscopic adrenalectomy and robotic adrenalectomy and summarize recent developments that may offer evidence for or against a paradigm shift in this specific field of endocrine surgery.

Effects of volume-controlled equal ratio ventilation with recruitment maneuver and positive end-expiratory pressure in laparoscopic sleeve gastrectomy: a prospective, randomized, controlled trial

Background/aim: We compared the effects of volume-controlled equal ratio ventilation (VC-ERV) and volume-controlled conventional ratio ventilation (VC-CRV) on oxygenation, ventilation, respiratory mechanics, and hemodynamic status during mechanical ventilation with recruitment maneuver (RM) and positive end-expiratory pressure (PEEP) in patients undergoing laparoscopic sleeve gastrectomy. Materials and methods: A total of 111 patients scheduled for laparoscopic sleeve gastrectomy were randomized to ventilation with inspiratory to expiratory ratio of 1:1 (Group VC-ERV) or 1:2 (Group VC-CRV) following tracheal intubation. RM (40 cmH2O, 15 s) and PEEP (10 cmH2O) were administered to all patients. Arterial blood gas samples were taken and peak airway pressure (Ppeak), mean airway pressure (Pmean), dynamic compliance (Cdyn), mean arterial pressure, heart rate, SpO2, and EtCO2 were recorded at 4 time points. Postoperative respiratory complications were recorded. Results: Oxygenation, ventilation, Pmean levels, and hemodynamic variables were similar in both groups. VC-ERV significantly decreased Ppeak and increased Cdyn compared to VC-CRV at all time points of the operation (P < 0.05). No pulmonary complication was observed in any patients. Conclusion: VC-ERV provides significantly lower Ppeak and higher Cdyn with similar oxygenation, ventilation, hemodynamic parameters, and Pmean levels when compared to VC-CRV during mechanical ventilation with RM and PEEP in laparoscopic sleeve gastrectomy.

Retrospective Evaluation of Patients who Underwent Laparoscopic Bariatric Surgery.

OBJECTIVE: In the present study, we aimed to retrospectively evaluate the preoperative characteristics, intraoperative and postoperative results of patients who underwent laparoscopic obesity surgeries. METHODS: After obtaining the approval of the Ethics Committee, records of patients who underwent laparoscopic obesity surgery from January 2013 to December 2016 were reviewed. Demographic characteristics, medications used in anaesthesia and analgesia, the duration of recovery unit/hospital stay, intensive care unit/mechanical ventilation requirements and complications were recorded. RESULTS: A total of 329 ASA II-III patients over a 3-year period were operated. Thiopental and propofol were administered at induction, sevoflurane, isoflurane and desflurane were administered for the maintenance, and vecuronium and rocuronium were administered to aid in neuromuscular blockage. The mean durations of recovery unit and hospital stays were 30.80±6.01 minutes and 4.27±1.68 days, respectively. The hypnotic agent, muscle relaxant or inhalation anaesthetics used did not have a significant effect on the duration of recovery unit and hospital stay. Mask ventilation and intubation were noted to be difficult in 5.5% and 8.5% of the cases, respectively. The presence of obstructive sleep apnoea syndrome and high body mass index and Mallampati scores significantly increased difficult mask ventilation and difficult intubation rates. Four patients were transferred to intensive care unit for close monitoring. Two patients were re-operated on, two patients had rhabdomyolysis, one patient had Wernicke's encephalopathy and two patients had peripheral neuropathy. Perioperative mortality did not occur in any patient. CONCLUSION: We believe that appropriate patient selection, the use of well-designed anaesthesia and surgical protocols play important roles in increasing the success rate of patient outcomes and early and late complications in laparoscopic obesity surgery.

Assessment of Atrial Fibrillation and Ventricular Arrhythmia Risk after Bariatric Surgery by P Wave/QT Interval Dispersion.

BACKGROUND: The association of obesity with atrial fibrillation (AF) and with ventricular arrhythmias is well documented. OBJECTIVE: The aim of this study was to investigate whether weight reduction by a laparoscopic sleeve gastrectomy has any effect on P wave dispersion (PWD), a predictor of AF, and corrected QT interval dispersion (CQTD), a marker of ventricular arrhythmias, in obese individuals. METHODS: In a prospective study, a total of 114 patients (79 females, 35 males) who underwent laparoscopic sleeve gastrectomy were examined. The patients were followed 1 year. PWD and CQTD values before and 3rd, 6th, and 12th months after the surgery were calculated and compared. RESULTS: There was a statistically significant decline in body mass index (BMI), PWD, and CQTD values among baseline, 3rd, 6th, and 12th months (p < 0.001 for all comparisons). Correlation analysis showed a statistically significant correlation between ΔPWD and ΔBMI (r = 0.719, p < 0.001), ΔPWD and Δleft ventricular end-diastolic diameter (LVEDD) (r = 0.291, p = 0.002), ΔPWD and Δleft atrial diameter (LAD) (r = 0.65, p < 0.001), ΔCQTD and ΔBMI (r = 0.266, p = 0.004), ΔCQTD and ΔLVEDD (r = 0.35, p < 0.001), ΔCQTD and ΔLAD (r = 0.289, p = 0.002). In multiple linear regression analysis, there was a statistically significant relationship between ΔPWD and ΔBMI (ß = 0.713, p < 0.001), ΔPWD and ΔLVEDD (ß = 0.174, p = 0.016), ΔPWD and ΔLAD (ß = 0.619, p < 0.001), ΔCQTD and ΔBMI (ß = 0.247, p = 0.011), ΔCQTD and ΔLVEDD (ß = 0.304, p < 0.001), ΔCQTD and ΔLAD (ß = 0.235, p = 0.009). CONCLUSION: PWD and CQTD values of patients were shown to be attenuated after bariatric surgery. These results indirectly offer that there may be a reduction in risk of AF, ventricular arrhythmia, and sudden cardiac death after obesity surgery.

Changes in serum lipid levels after laparoscopic sleeve gastrectomy in morbidly obese dyslipidemic and normolipidemic patients.

BACKGROUND: This study investigated the effect of laparoscopic sleeve gastrectomy (LSG) performed for morbid obesity on serum lipid levels of dyslipidemic and normolipidemic patients. METHODS: 141 patients who underwent LSG between September 2014 and January 2016 were included in the study. RESULTS: The patients' mean body mass index was 46.27 ± 6.79 kg/m2 preoperatively, 31.60 ± 5.37 kg/m2 in the 6th month postoperatively and 27.80 ± 4.25 kg/m2 in the 12th month (p < .001). Preoperatively and 12 months after the operation, mean total cholesterol (TC) levels and mean LDL cholesterol, mean HDL cholesterol, and mean triglyceride (TG) levels were statistically significantly decreased (p < .01). Comparing TC levels in the 12th month with preoperative levels, dyslipidemic patients showed a statistically more significant decrease than normolipidemic patients. LDL cholesterol levels were significantly decreased in both the groups. HDL cholesterol levels increased significantly in both groups while mean TG levels decreased significantly in patients with high preoperative TG levels, but not in patients with normal preoperative TG levels. CONCLUSIONS: Although this technique exerts its effect primarily by reducing gastric volume, besides its metabolic and hormonal effects, it also improves serum lipid levels (decreasing TC, LDL cholesterol and TG levels, and increasing HDL cholesterol levels). It therefore contributes to decreasing cardiovascular diseases.

Reliability of fine needle aspiration biopsy in large thyroid nodules.

OBJECTIVE: Fine needle aspiration biopsy provides one of the most important data that determines the treatment algorithm of thyroid nodules. Nevertheless, the reliability of fine needle aspiration biopsy is controversial in large nodules. The aim of this study was to evaluate the adequacy of fine needle aspiration biopsy in thyroid nodules that are four cm or greater. MATERIAL AND METHODS: We retrospectively examined 219 patients files who underwent thyroidectomy for thyroid nodules that were greater than four centimeter between May 2007 and December 2012. Seventy-four patients with hyperthyroidism, and 18 patients without preoperative fine needle aspiration cytology were excluded from the study. Histopathologic results after thyroidectomy were compared with preoperative cytology results, and sensitivity and specificity rates were calculated. RESULTS: False-negativity, sensitivity and specificity rates of fine needle aspiration biopsy of thyroid nodules were found to be 9.7%, 55.5%, and 85%, respectively. Within any nodule of the 127 patients, 28 (22.0%) had thyroid cancer. However, when only nodules of at least 4 cm were evaluated, thyroid cancer was detected in 22 (17.3%) patients. CONCLUSION: In this study, fine needle aspiration biopsy of large thyroid nodules was found to have a high false-negativity rate. The limitations of fine-needle aspiration biopsy should be taken into consideration in treatment planning of thyroid nodules larger than four centimeters.

Efficacy of simvastatin in reducing postoperative adhesions after thyroidectomy: an experimental study.

BACKGROUND: We aimed to investigate whether simvastatin had any impact on the prevention of adhesion formation after thyroidectomy in a rat model. METHODS: This study was performed in 66 Wistar albino rats randomized into three experimental groups. A right hemithyroidectomy was carried out in all the rats. Simvastatin was administered locally at a dose of 0.5 mg/kg and 0.8 mg/kg. Control rats received a saline solution only. Changes during the 1st week, 1st month and 3rd month were evaluated. Efficacy of the treatment was assessed by using a scoring system. RESULTS: The severity of adhesions in low-dose simvastatin group was significantly less than the control and high-dose groups during the 1st and 3rd month (p < .05). In addition, adhesions were less in the high dose group during the 3rd month, when compared to the control group (p < .05). Moreover, fibrosis and fibroblast scores, which represent adhesions, were significantly lower in low-dose and high-dose groups at 3rd month, compared to controls (p < .05). CONCLUSIONS: We investigated the influence of simvastatin application on post-thyroidectomy adhesion formation in rats. Whether adhesions, causing technical difficulties during neck redo surgery, can be reduced by the use of simvastatin in human, needs to be studied.

Retroperitoneal paraganglioma presenting with pancytopenia: A rare case with rare manifestation.

INTRODUCTION: Paragangliomas are tumors that arise from extraadrenal chromaffin cells and most of them are asymptomatic presenting with painless mass. Retroperitoneal paragangliomas are mostly benign with good prognosis; however, they can present with abdominal pain, palpable mass, or hypertensive episodes. Surgical resection is still the main treatment and necessary for histological assessment. CASE REPORT: A 41 year old female patient presented with 6 months of loss of appetite, weight loss, weakness and breathlessness on exertion.. The patient's initial blood examination showed marked anemia, reduced leukocyte count with neutropenia and lymphopenia and a marked reduction in the platelet count. The patient was admitted for evaluation of her pancytopenia. Magnetic resonance imaging revealed a 8×7×8cm sized mass closed to the pancreatic tail invading splenic hilum. A large mass was identified retroperitoneally, closed to the tail of pancreas with a splenic hilum invasion. Total mass resection and splenectomy was performed. DISCUSSION: Complete surgical excision is the treatment of choice for extra-adrenal paragangliomas as well as for recurrent or metastatic neoplasms. Reactive thrombocytosis is a common cause of thrombocytosis. Splenectomy was found to be one of the main causes of extreme reactive thrombocytosis. Reactive thrombocytosis is a predictable finding after splenectomy and management of the thrombocytosis and prevention of complications should be initiated.

Surgeons' Approaches and Professional Perspectives on Breast Masses: A National Survey in Turkey.

OBJECTIVE: General surgeons' approaches to breast masses in their daily practices and their perspectives for issues on breast diseases and breast surgery are investigated through a survey. MATERIALS AND METHODS: Answers of 524 general surgeons for the survey "Approach to breast diseases and breast surgery" between November 2012 and February 2013 were assessed. Demographic features, approaches to the breast masses, and answers for the clinical scenerios of surgeons were questioned. Surgeons were asked about management of breast cancer and the future role of surgeons for oncoplastic breast surgery and breast diseases. RESULTS: Participants were representing 14.6% of all general surgeons in Turkey. The survey revealed that breast diseases are the most common cause for admission in general surgery outpatient clinics. Needle biopsies were employed by 241 (60%) respondents. Three hundred and seventy-one (71%) participants indicated that breast cancer management could be accurately conducted by the general surgeons. Two hundred and seventy-three (52%) respondents think that oncoplastic breast surgery should be performed by a general surgeon and 241 (41%) respondents predict that the role of general surgeons for breast diseases and breast surgery will decrease in the future. CONCLUSION: Basic approaches towards breast masses need to be improved in our country despite the highest frequency of breast diseases in outpatient admissions. The views and opinions of surgeons on breast diseases and the course of breast surgery in different regions and different communities need to be defined and clarified.

Papillary thyroid cancer, macrofollicular variant: the follow-up and analysis of prognosis of 5 patients.

Objective. The main aim of this study was to comparatively analyze the recurrence and prognosis of this rare variant with the literature by analyzing the follow-up data of 5 patients diagnosed with papillary cancer macrofollicular variant. Methods. The demographic data, radiological and pathological data, and prognostic data of 5 patients who underwent surgery for thyroid cancer and were diagnosed with papillary cancer macrofollicular variant pathologically were retrospectively analyzed. Results. The mean age of patients whose mean follow-up period was determined as 7.2 years was 41, and the male/female ratio was 4/1. All patients underwent total thyroidectomy. The pathology report of 2 patients (40%) revealed macrofollicular variant of papillary microcancer, and 3 patients papillary cancer macrofollicular variant. Central dissection was performed in one patient (20%) due to macroscopic pathologic lymph node and 4 metastatic lymph nodes were reported. Also, locoregional recurrence was present in 3 out of 5 patients (60%). Conclusions. Although an impression of earlier and increased risk of recurrence in papillary carcinoma with macrofollicular variant has been documented, more studies with extensive follow-up times and large populations are required.

Isolated metastasis of uterine leiomyosarcoma to the pancreas: Report of a case and review of the literature.

INTRODUCTION: Metastatic tumors of the pancreas are uncommon and rarely detectable clinically. Metastases to the pancreas are rare. We present a patient with pancreatic metastases from a leiomyosarcoma of the uterus and review the literature about the clinical features of pancreatic metastasis and its surgical management. PRESENTATION OF CASE: A 40-year-old woman, who underwent hysterectomy, left oophorectomy, omentectomy and lymp node dissection for leiomyosarcoma of the uterus. At the follow up, the patient complained of non-specific abdominal discomfort. Preoperative diagnosis were pancreatic pseudocyst, cystadenoma or cystadenocarcinoma. At laparotomy, a cystic mass was found in the tail of the pancreas which was invased to the transverse colon mesenterium and the spleen. Distal pancreatectomy with splenectomy and transverse colon resection was performed. Histologically, the tumor was evaluated as poorly differentiated leiomyosarcoma. DISCUSSION: Metastatic lesions of the pancreas are uncommon and less than 2% of all pancreatic malignancies. However a few cases of leiomyosarcoma with metastases to the pancreas have been reported in the literature. Before deciding that the lesion in the pancreas was metastasis, primary leiomyosarcoma of the pancreas had to be ruled out. Histologically, leiomyosarcoma of the pancreas contains interlacing spindle cells with varying degrees of atypia and pleomorphism. The surgical approach to the pancreatic metastases must be aimed complete excision of the tumor with a wide negative margin of clear tissue and maximum preservation of pancreatic remnant if possible. CONCLUSION: In the absence of widespread metastatic disease, aggressive surgical approach with negative margins must be aimed.

Isolated retroperitoneal hydatid cyst invading splenic hilum.

Introduction. Hydatid disease (HD) is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT) revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR) technique is another nonsurgical option.

The approach of general surgeons to oncoplastic and reconstructive breast surgery in Turkey: a survey of practice patterns.

BACKGROUND: Oncoplastic Breast Surgery (OBS), which is a combination of oncological procedures and plastic surgery techniques, has recently gained widespread use. AIMS: To assess the experiences, practice patterns and preferred approaches to Oncoplastic and Reconstructive Breast Surgery (ORBS) undertaken by general surgeons specializing in breast surgery in Turkey. STUDY DESIGN: Cross-sectional study. METHODS: Between December 2013 and February 2014, an eleven-question survey was distributed among 208 general surgeons specializing in breast surgery. The questions focused on the attitudes of general surgeons toward performing oncoplastic breast surgery (OBS), the role of the general surgeon in OBS and their training for it as well as their approaches to evaluating cosmetic outcomes in Breast Conserving Surgery (BCS) and informing patients about ORBS preoperatively. RESULTS: Responses from all 208 surgeons indicated that 79.8% evaluated the cosmetic outcomes of BCS, while 94.2% informed their patients preoperatively about ORBS. 52.5% performed BCS (31.3% themselves, 21.1% together with a plastic surgeon). 53.8% emphasized that general surgeons should carry out OBS themselves. 36.1% of respondents suggested that OBS training should be included within mainstream surgical training, whereas 27.4% believed this training should be conducted by specialised centres. CONCLUSION: Although OBS procedure rates are low in Turkey, it is encouraging to see general surgeons practicing ORBS themselves. The survey demonstrates that our general surgeons aspire to learn and utilize OBS techniques.

A rare cause of mechanical obstruction: Intestinal myeloid sarcoma.

Myeloid sarcoma is a rare aggressive tumour that originates from immature extramedullary myeloid cells. It can be seen as a relapse in patients with acute myeloid leukaemia. Sometimes it can be seen in the form of a solid tumour without any evidence of leukaemia. A case of a 44-year-old male patient who was admitted with symptoms and signs of mechanical intestinal bowel obstruction was operated on. The operation findings showed small bowel obstruction due to a mass. The mass was then resected with end-to-end intestinal anastomosis. The resected mass pathology results were consistent with myeloid sarcoma. The post-operative period was uneventful and adjuvant therapy was applied. In this case report we aimed to evaluate the clinical signs and treatment modalities of small intestinal myeloid sarcoma.

The importance of staging systems for the determination of prognosis of well-differentiated thyroid cancer.

OBJECTIVE: In this study, we aimed to determine the significance of the staging systems (EORTC, De Groot, MACIS, and TNM) on the prognosis of well-differentiated thyroid cancer patients who underwent surgery in our clinics. MATERIAL AND METHODS: This retrospective study included 181 patients who were operated between December 1995-December 2007, with a diagnosis of thyroid cancer. In order to obtain data related to cancer staging, a computer program for PDA was developed to facilitate parameter recording. Survival analysis was performed. The findings were compared to the predicted rates by the staging systems. RESULTS: According to the De Groot staging system, stage 1 and stage 2 patients' results were compatible, but stage 3 and 4 patients' results were different (stage 3; 87% versus 66.6%, stage 4; 35% versus 100%, p=0.04). In the MACIS staging system, 20-year survival rates are determined and comparison should not be made due to insufficient follow-up period in this study. When compared to the EORTC staging system, stage 3 and stage 4 patients' results were determined different (stage 3; 51% versus 100%, stage 4; 33% versus 50%, p=0.02). The most consistent results in terms of prognosis was determined in comparison with the TNM staging system (stage 1; 100% versus 97.8%, stage 4; 45.3% versus 50%). CONCLUSION: Many classification systems are proposed for well-differentiated thyroid cancer, to predict the behavior of the tumor. In this study, we concluded that for determination of prognosis in well-differentiated thyroid cancer, the TNM staging system could best predict prognosis consistent with clinical findings.
