Background: Obesity is one of the important chronic diseases with high growth in worldwide and bariatric surgery is currently considered the most effective treatment for weight reduction. Objectives: We aimed to analyze weight loss follow up and diabetes management in patients submitted to mini gastric bypass on use of vitamin and mineral supplementation, in the new set up center, in Mazandaran province for the first time. Methods: Prospective analysis of 27 volunteers of both sexes, aged between 23 52 years, using laparoscopic mini gastric bypass in Sari’s Avicenna hospital, were included; personal information, anthropometric and laboratory data in the preoperative, 3, 6 and 9 months were collected. Statistical analysis was done with SPSS, 19 and using the Wilcoxon and Friedman test. Results: During follow up time after 276 days mean weight decreased from 118.7 ± 23.3 to 82.9 ± 15.7, P < 0.001 BMI also changed from 45.2 ± 1.8 to 32.2 ± 1.3, P < 0.001. There was decrease in percentage of excess weight loss at month of 3, 6 and 9 were 52.1, 32.6 and 16.4 respectively. Fasting blood sugar in diabetic subjects (n = 16) decreased from 170.9 ± 84.5 to 89.8 ± 11.3, P = 0.04. Conclusions: In the newly set up center similar to the older one, surgical treatment in our follow up duration was effective for reducing weight, body mass index reduction and achievement of success in biochemical markers on diabetics.

Introduction: Ileal diverticulum is a rare disease that presents with complications such as diverticulitis. Case Presentation: We present an 81-year-old man with partial small bowel obstruction having abdominal pain, nausea, vomiting for 48 hours and a mobile abdominal mass. After CT scan, exploratory laparoscopy and small bowel resection was done with primary anastomosis. Conclusions: When adhesion, internal hernia and malignancy are ruled out in patient presenting with partial obstruction and abdominal mass, other causes like diverticula must be considered.

Background: ProspectivestudiesevaluatingoutcomeoflaparoscopicHellermyotomyandDorfundoplicationforesophagealacha-lasia are less in Asian people. Objectives: This study conducted to evaluate the results of laparoscopic cardiomyotomy and partial fundoplication for achalasia. Patients and Methods: Thirty patients who underwent Heller myotomy for achalasia via laparoscopy in Alzahra hospital Isfahan, Iran were recorded prospectively (2009 - 2013). Median follow-up was 18 months. Symptoms including dysphagia, regurgitation, chest pain and weight loss were recorded before and after operation. Also, previous treatment for achalasia such as endoscopic pneumaticdilatationsandintrasphinctericinjectionof botulinumtoxinorothercomponent,durationof symptomsandduration and complication of operation was recorded. Results: Among 30 patients, there were 13 (43.3%) females and 17 (56.7%) males, and mean age was 40.8 years (range, 20 - 68 years). The operations were finished laparoscopically in all patients. Mean operative time was 137 ± 36.2 minutes. The patients were symptomatic for at least 30 months before referring for surgery. There are some difficulties in dissection in cases who received Ethanolamine or Botholinum Toxin injection as non-surgical treatment before that. Mean hospital stay was 2.45 days. Regurgitation, chest pain and heartburn relieved significantly in median follow up of 18 months, in 100%, 66.6% and 70%, respectively (P < 0.001, P < 0.01 and P < 0.01, respectively).

Background: Considering the importance of providing vitamins and minerals in body health, it obviously seems to be necessary to assess the deficiencies of these nutrients in obese patients. Objectives: The present study aimed to evaluate the level of hemoglobin, ferritin, and vitamin B12 in a sample of Iranian population with morbid obesity. Patients and Methods: This cross-sectional study was conducted on 1252 consecutive patients with morbid obesity referred to obesity clinic at Rasoul-e-Akram hospital from 2009 to 2015 in Tehran, IR Iran. Morbid obesity was defined as body mass index (BMI) equal to or higher than 40 kg/m 2 . Serum hemoglobin level (gr/dL) was measured using the cyan methemoglobin method. Serum ferritin level (ng/mL) can be measured by the human ferritin enzyme immunoassay test. Also, serum vitamin B12 concentration (pg/mL) was measured using the solid-phase, competitive chemiluminescent enzyme immunoassay method. Results: Overall, 1252 patients with morbid obesity were included in the study. The mean age of participants was 39.77 10.84 years (ranged 10 to 70 years) and 80.3% of them were female. The mean body weight was 126.75 21.58 kg and the mean BMI was also 46.99 5.87 kg/m 2 . In result, 9.8% were anemic according to the low value of hemoglobin level, 46.6% had ferritin lower than the normal range and the average serum level of vitamin B12 was lower than the normal value in 21.1%. By applying the Pearson's correlation test, a positive association was found between BMI value and the level of hemoglobin (r = 0.074, P = 0.009). Conclusions: Morbid obesity may result in two important hematologic and metabolic changes including increased hemoglobin level and reduced vitamin B12 level. Since, vitamin B12 has vital role in the body, providing adequate vitamin B12 is essential in these patients even by using vitamin supplements. Also, regular screening of the level of hematologic markers in these patients is strongly

Preserving normal tissue during surgery has become increasingly important for better outcome after operation. Because of this, minimally invasive procedures have been developed. There are many pain procedures with minimally invasive method to aid fluoroscopy. The percutaneous vertebroplasty or kyphoplasty instead of screw fixation for many kinds of compressed fractures with 90% success rate is a good example (1). The percutaneous radiofrequency ablation of medial branch of dorsal ramus for facet mediated vertebral pains is another example with good results (2). The percutaneous trigeminal ganglion radiofrequency ablation instead of microvascular decompression in elderly people has success rate of 80% 90% (3). Spinal column stimulator and intrathecal pump implantation are expensive and useful methods of treating persistent pains such as failed back surgery syndrome and CRPS (4). Recently, the percutaneous transformational decompression of disc with ozone or laser or coblation in bulging or moderate protrusion of lumbar or cervical discs or in disco genic pain instead of discectomy or screw fixations, have become popular. In 1973, Kambin (originally Iranian orthopedic surgeon) started percutaneous decompression of disc by nucleotomy in USA (5). Later, he reported 72 percent success rate with modified Hijikata approach (6). In 1985, Onik et al. introduced nucleotomy with motorized shaver (7). Ascher performed the first laser discectomy in mid-1980s. He used Nd: YAG laser and the good to fair range response to that method was 78% (8). Minimally invasive percutaneous transforaminal endoscopic discectomy was initiated by Kambin in 1988. Kambin described The triangular safe zone in transforaminal approach in 1990 (4). Tsou and Yeung, in 2002 , reported the same efficacy for endoscopic discectomy and conventional open surgery (9). They reported 91% success rate for this approach (10). Nevertheless, there are some failed cases such as migrated fragments or high canal compromised herniation (11). With recent advances, endoscopic discectomy will gradually replace open discectomy in near future.

Context: The human Nucleus Accumbens (NA) constitutes nowadays a target of deep brain stimulation (DBS) for selected patients mainly suffering from some psychiatric disorders. Mavridis’ Area (MA) of the human brain is the most reliable stereotactically standard part of the NA, regardless of side or gender. Primary purpose of this review article was to discuss the MA as a stereotactic microanatomic target for NA DBS application, emphasizing on technical aspects of targeting the MA. Evidence Acquisition: A detailed search of the current literature regarding MA was applied. The critically reviewed literature was then used to discuss the MA as a stereotactic microanatomic target for NA DBS application, emphasizing on technical aspects of targeting the MA. The suggestion of future research directions was also aimed. Results: Following the currently used trajectory through the anterior limb of the internal capsule (ALIC) in combination with the principles of the ‘port model’, a DBS electrode placement within the NA, targeting the MA, is feasible. MA could be the target area of one, only, of the electrode contacts, preferably contact 1 or 2. It could be also the target area for contact 0 in ALIC DBS and even the target for a combined NA-ALIC DBS. MA is the first and most representative example of the evolution of stereotactic anatomy into stereotactic microanatomy, in order to serve the development of the field of stereotactic microneurosurgery. Conclusions: MA is nowadays the most accurate stereotactic anatomic guide for targeting the human NA. It is a representative example of how stereotactic microanatomy could serve the development of stereotactic microneurosurgery. Following the currently used trajectory through the ALIC, a DBS electrode placement within the NA, targeting the MA, is feasible, allowing either NA or ALIC stimulation. Simultaneous stimulation of the NA and ALIC is also possible with this application.

Evidence Acquisition: A detailed search of the current literature regarding MA was applied. The critically reviewed literature was then used to discuss the MA as a stereotactic microanatomic target for NA DBS application, emphasizing on technical aspects of targeting the MA. The suggestion of future research directions was also aimed. Results: Following the currently used trajectory through the anterior limb of the internal capsule (ALIC) in combination with the principles of the ‘port model’, a DBS electrode placement within the NA, targeting the MA, is feasible. MA could be the target area of one, only, of the electrode contacts, preferably contact 1 or 2. It could be also the target area for contact 0 in ALIC DBS and even the target for a combined NA-ALIC DBS. MA is the first and most representative example of the evolution of stereotactic anatomy into stereotactic microanatomy, in order to serve the development of the field of stereotactic microneurosurgery. Conclusions: MA is nowadays the most accurate stereotactic anatomic guide for targeting the human NA. It is a representative example of how stereotactic microanatomy could serve the development of stereotactic microneurosurgery. Following the currently used trajectory through the ALIC, a DBS electrode placement within the NA, targeting the MA, is feasible, allowing either NA or ALIC stimulation. Simultaneous stimulation of the NA and ALIC is also possible with this application.","PeriodicalId":158928,"journal":{"name":"Journal of Minimally Invasive Surgical Sciences","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134392326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
