Abstract
Background: For patients requiring chronic hemodialysis, the preferred site for vascular access is an autogenous arteriovenous fistula. Although a properly formed fistula is advantageous because it is less susceptible than other types of vascular accesses to infection and clot formation and can last longer than any other types of vascular access, AV fistula has a high rate of early failure that can increase immediate cost and complications. In this study, the prognostic value of physical examination of arteriovenous fistula by the surgeon at the end of the surgery was evaluated.
Methods: In the general surgery ward of Imam Khomeini Hospital in 326 chronic renal failure patients, 354 arteriovenous fistula operations were accomplished by two surgeons from 1377 to 1381 (ca. 1998 to 2002). The performance of each fistula was divided into the following groups by the surgeon at the end of operation: 1) systolic and diastolic thrill, 2) systolic thrill 3) souffle 4) pulse 5) not functional. Clinical function of the fistula was evaluated by the same surgeon in the following days if no souffle or thrill, early failure was detected on initial inspection.
Results: In the 354 cases of arteriovenous fistula, the total early failure rate was 12.7%. The lowest early-failure rate was 3.5% in the systolic and diastolic thrill group. The highest early-failure rate was in the not functional group (P<0.001). There was no correlation between early failure and age, sex, surgeon and location of fistula.
Conclusion: Optimally, an arteriovenous fistula has a thrill with a soft compressible pulse. At the end of each operation, if the surgeon cannot detect a thrill at the fistula site, can find only pulse, or if the function is otherwise unsatisfactory, considering of a new arteriovenous fistula may be required, however it is better to postpone the surgery.

Abstract
Background: surgical site infection is one of the most common post operative complications alongside with sepsis, cardiovascular, pulmonary and thromboembolic complications. The development of surgical site infection is related to three factors: the degree of microbial contamination of the wound during surgery, the duration of the procedure, and host factors such as diabetes, malnutrition, obesity, immune suppression, and a number of other underlying disease states. The purpose of this study was to evaluate the effects of topical cephazolin in controlling infection of the site of surgery after non-laparoscopic cholecystecomy.
Methods: One hundred and two of patients referred to the outpatient clinic of Imam Khomeini Hospital from fall 2005 to fall 2006 non- laparoscopic cholecystectomy enrolled in a randomized clinical trial. All patients underwent the same procedure of anesthesia and surgery and they were randomly assigned into two groups of cases with irrigation of the site of surgery with 1g of topical Cephazolin prior to the termination of the operation- and controls. Cephazolin is a first generation cephalosporin which binds penicillin binding protein and is a potent cell wall synthesis inhibitor. The patients were followed up for six weeks for symptoms and signs of infection including discharge of the wound and presence of pain, warmness, swelling and erythema of the wound.
Results: There were no significant differences between two study groups regarding mean age, duration of operation, and sex. There was no significant difference in the incidence of infection of the site of surgery (11.8% in both groups with p=0.99) between two groups.
Conclusion: Analyzing the collected data confirms that prophylactic use of topical cephazolin was unable to decrease the risk of infection of the site of surgery in patients undergoing non- laparascopic cheolecystectomy.

Abstract
Background: Myasthenia Gravis (MG) is a neuromuscular disorder with weakness of skeletal muscles. Thymectomy is now recognized as a treatment modality in MG. The aim of this study was to evaluate the clinical effect of thymectomy on MG.
Methods: MG patients with history of thymectomy at a tertiary referral center during twelve year period were included. The medical records were reviewed and telephone survey was conducted to evaluate the effects of thymectomy.
Results: Sixty MG patients, 46 females and 14 males, aged 30.4±11.1 years, underwent open (n=48) or video-assisted thoracoscopic thymectomy (n=12) during study period. The mean dosage of preoperative pyridostigmine was 235.4±86.2mg/day. This figure reached to 129±18mg/day after thymectomy (p<0.0001). 17 patients (28.3%) had complete remission (complete freedom of symptoms without medications). Improve-ment (improved symptoms or less medication requirement) was seen in 34 patients (56.6%). There was no response to surgical therapy in six patients (10%). Three patients (5%) had experienced progression of disease postoperatively. Overall, benefit of thymectomy was observed in 85% of patients. Age, sex, duration and severity of disease, quantity of preoperative drugs, surgical approach, and presence of thymoma did not affect the outcome. Satisfaction was stated as excellent in 17%, good in 43%, moderate in 35% and poor in 5% of patients after operation.
Conclusion: Thymectomy is an effective treatment for MG which leads to less severity of disease and less drug requirement. It would be considered in all myasthenic patients regardless of age, sex, duration and severity of disease and presence of thymoma.

Abstract
Background: Gall stone is an important health problem in the world for which different risk factors have been characterized. Gall stone and cardiovascular disease have common risk factors. Homocysteine is accepted as one of the risk factors for cardiovascular disease. We aimed to study the effect of homocysteine level on gall stone formation.
Methods: 54 patients with gall stone-related diseases and 54 patients without stone (control group) were studied from January 2007 to December 2008. Control group consisted healthy subjects with ultrasound proven normal gallbladder. Serum homocysteine level was checked in both groups. Homocysteine level of equal or more than 15 mmol/l was considered as abnormally high.
Results: Cases included 43 women (79.6%) and had mean age of 50.76±15.23 years. Homocysteine level was significantly higher in patients with gallstone in comparison to control group (p=0.014). Risk of gall stone increased 3.4 times in persons who have homocysteine level equal or greater than 15mmol/l (p=0.019). The mean level of homocysteine was higher in men than women (p=0.03). The mean level of homocysteine did not differ significantly in patients with simple gallstone and patients with gallstone-related inflammation disorders (cholecystitis, cholangitis, and pancreatitis). Additionally, one unit increase in BMI level was associated with 1.12 times increase in the risk for gall stone formation (p=0.035).
Conclusion: The homocysteine level is increased in patients with gall stone-related diseases. Homocysteine may be considered as a risk factor of gall stone formation.

Abstract
Background: Prevalence of Abdominal Aortic Aneurysm (AAA), estimated by various studies, ranged from 4.1% to 14.2% in men older than 60 years. Most cases of AAA are asymptomatic and often discovered incidentally. Approximately the initial presentation in 12% of cases of AAA is sudden rupture with subsequent high mortality. This study was performed to evaluate the prevalence and screening necessity of AAA among Iranian men older than 65 years old.
Methods: In this cross-sectional study, men older than 65 years, who referred for ultrasound examination to three different centers in Tehran, Iran at the year 2008 were included for evaluation of size of the abdominal aorta and presence of AAA.
Results: A total of 240 men older than 65 years enrolled in this study. AAA was found in 24 of the participants with prevalence rate of 10% in the studied population. Mean diameter of detected aneurysms was 3.931.435 cm. In 4 (1.7%) subjects, aneurysms greater than 5.5 cm in diameter were detected. One of these four subjects had the history of coronary artery disease and one was cigarette smoker. Three out of four had history of hypertension.
Conclusion: Considering the estimated prevalence rate of AAA by the current study and the population of Iranian men older than 65, implementing of mass screening for AAA in this group would detect 986 asymptomatic cases each year. Therefore, the authors recommend further studies about the cost-effectiveness of mass screening for AAA among Iranian men above 65 years.

Abstract
Background: The purpose of this study was evaluation of risk factors of peripheral artery disease (PAD) and effective markers on it.
Methods: This descriptive-analytical study was done during 2010-2011 in the surgical units of Khorramabad Shohada Hospital. Fifty patients who had symptoms of PAD undergoing CT angiography and biochemical markers for them were measured. The investigated variables were family history, site of arterial obstruction, underlying diseases, smoking history, physical activity and stress level. A control group was considered for the study. The comparison was made between these two groups.
Results: Aging showed a significant role in prediction of PAD (70% sensitivity and 64% specificity). Homocysteine had the highest sensitivity (80%) in prediction of PAD, compared with other biomarkers. CRP (74% sensitivity) was the best marker that had positive predictive value for PAD. Fasting blood sugar (FBS) showed a significant role in prediction of true positive cases of PAD (72% sensitivity and 74% specificity). HbA1C with 68% sensitivity and 64% specificity and TG with 50% sensitivity and 44% specificity could be considered as factors related with PAD.
Conclusion: The levels of C-Reacative protein, homocysteine, and FBS were correlated with PAD, HbA1C and TG levels were associated with PAD, but lower than the previously named markers. In this study a significant relationship between lipoprotein levels and PAD was also observed. PAD was associated with sex and age.

Abstract
Background: Lower gastrointestinal bleeding, a symptom that can become the cause of a life-threatening condition, has a 33 per 100,000 prevalence. The origin of lower gastrointestinal bleeding in most cases is the small intestine, colon, or anorectal parts. Surgical consultation in patients with gastrointestinal bleeding is one of the most necessary measures so that the patient can be treated at the appropriate stage with a greater chance of success before reaching shock. In the case of uncontrolled gastrointestinal bleeding, surgery is recommended as soon as possible when endoscopic and radiological treatments are not possible or effective.
Case Presentation: In this article, we present a case of uncontrolled lower gastrointestinal bleeding in a 50-year-old patient who was admitted to Imam Khomeini Hospital in Tehran on December 15, 2021. Despite performing appropriate paraclinic measures such as sonography, endoscopy, and colonoscopy the gastrointestinal bleeding origin was not determined. On the other hand, our investigations showed that she had liver cirrhosis. Due to the instability of the patient's condition due to continued lower gastrointestinal bleeding, the medical team decided to perform surgery. The surgeon noticed that the origin of the bleeding was a vascular entanglement at the small intestine-navel junction, and the procedure involved segmental excision of the small intestine.

Conclusion: In cirrhotic patients, lower gastrointestinal bleeding is an emergency condition, and if the source of the bleeding is not accessible via endoscopy or colonoscopy, diagnosing and treatment become extremely difficult. Computed tomography angiography and subsequent surgery are effective approaches for diagnosing and treating these conditions. When lower gastrointestinal bleeding is uncontrolled, exploratory laparotomy should be considered. Due to the unknown origin of bleeding, exploratory laparotomy may not be successful, so using endoscopy during surgery can help to diagnose the location of the lesion in these cases; However, in some cases despite all measures, the source of bleeding may not be determined, in these case the rate of rebleeding after surgery will be high.
