There is a lack of adequate predicted data on quality of life (QOL) among these patients. The aim of the study is to evaluate changes in physical and social functioning, pain, and mental health after LSG surgery. Methods This retrospective study evaluated QOL by using the obesity-specific Moorehead-Ardelt quality of life questionnaire II (MAII) and Medical outcomes survey short form 36 (SF-36) health survey. The questionnaires were used for a group of 120 patients underwent LSG in Shiraz. Demographics, quality of life were measured by questionnaires which filled by all patients and compared with whom were scheduled for surgery. In terms of statically significance, it is valuable when the P value is under < 0.05 in comparing two groups. Results Their initial mean (SD) of body mass index (BMI) was 48.87 (1.38) kg/m2. Six months after surgery, the mean (SD) of weight loss in patients was 36.15 (3.9) kg. Median follow-up point of patients was 14.5 months (range, 2 - 46 months). The median MAII score was 6.48 ± 0.45 after surgery with no significant difference in the comparison of pre-operation (P = 0.275), but the SF-36 scores were statistically different in all parameters (P < 0.05) except for “role limitations attributed to emotional problems” and “mental health” with no significant difference (P = 0.080, 0.074, respectively). Conclusions The outcomes of LSG operation compared with the pre-operation status of patients depicted that LSG is a satisfactory and effective bariatric procedure. Also, resolution of comorbidity is an important aspect and is comparable with other reports. http://annbsurg.iums.ac.ir/article-1-222-en.pdf 2018-02-15 100 110 Quality of Life Obesity Laparoscopic Sleeve Gastrectomy Long-Term Results

Even mild to moderate weight loss has been shown to improve physical function. This study aimed to evaluate the effect of Roux-en-y gastric bypass (RYGB) surgery on some fitness parameters in women with morbid obesity. Methods Seventy two women with morbid obesity body were included in this study. They were followed for six months after RYGB surgery. Some fitness parameters including body composition (using bioelectrical impedance), muscular strength (leg press in lower limb and hand power grip in upper limb) and six minute walk test (6MWT) were evaluated before surgery and that at intervals of 1, 3 and 6 months after surgery. One way repeated measure ANOVA was applied to determine the data changes during the follow up period. Results BMI and body weight of all samples declined constantly during 6 months follow up after surgery. Also, by the end of the study, the body fat percent decreased from 48.2 (3) to 36.4 (4) (P < 0.05). The distance which patients paced in 6MWT increased 22% during 6 months follow up (P < 0.0001). Although handgrip and leg press of the participants decreased following the gastric bypass surgery, the power grip/weight ratio and leg press /weight ratio improved significantly through the study (P < 0.0001). Conclusions RYGB surgery may positively affect fitness parameters in morbid obese women. The endurance capacity, body composition and even muscle strength seem to be enhanced after gastric bypass surgery. http://annbsurg.iums.ac.ir/article-1-224-en.pdf 2018-02-15 100 110 RYGB Morbid Obesity Fitness 6MWT Power Grip Leg Press

CASE_STUDY http://annbsurg.iums.ac.ir/article-1-221-fa.pdf 2018-02-15 100 110 Introduction Angiofibroma is a benign, un-encapsulated, and highly vascular tumor which typically arises from the pterygopalatine fossa in the young adolescent males. It predominantly extends into the nasopharynx and rarely develops extranasopharyngeally. However, the most common origins of extranasopharyngeal angiofibromas are the maxillary sinus, ethmoid sinus and nasal cavity. Case Presentation Here, we report a 40-year-old male who presented with headache and epistaxis and was diagnosed as an extranasopharyngeal angiofibroma originated from the sphenoid sinus. The tumor was completely resected endoscopically. The 24-month follow-up showed no recurrence. Conclusions Angiofibromas should be considered as a possible diagnosis in any unilateral vascular mass of the nasal cavity, even in the older patients without typical imaging patterns. http://annbsurg.iums.ac.ir/article-1-221-en.pdf 2018-02-15 100 110 Nasopharynx Angiofibroma Nasopharyngeal Neoplasms Paranasal Sinuses Sphenoid Sinus Endoscopy

Experimental studies, entitled randomized controlled trials could test the relationship between exposure and outcome experimentally via control group and random allocation. Observational settings include either analytical or descriptive studies. Descriptive studies consist of case reports and case series that are helpful in present the experience of a case or a series of cases with similar diagnoses in detail which results in hypothesis generation. Cross-sectional studies, as analytical designs, are not capable to survey the temporality of exposure and outcome as simultaneously exposure and outcome status are measured. In case-control studies, subjects follow back from outcome to exposure. The rare diseases are recommended to study using case-control setting to save expenses and time. Both exposure measurement and patient selection is before disease detection in cohort studies. Therefore, they are inefficient for rare diseases or diseases with long latency. Cohort studies are time consuming with high cost and loss to follow-up. This paper elaborately reviews the features, advantages, and disadvantages of different types of observational and experimental studies. http://annbsurg.iums.ac.ir/article-1-223-en.pdf 2018-02-15 100 110 Observational Studies Case-Control Studies Cohort Studies Bariatric Surgery Experimental Studies Review
