Effect of bariatric surgery on adiposity and metabolic profiles: A prospective cohort study in Middle-Eastern patients.

AIM: To investigate changes in adiposity and cardio-metabolic risk profile following Roux-en-Y gastric bypass in patients of Middle Eastern ethnicity with severe obesity. METHODS: This prospective cohort study involved 92 patients who met the indications of bariatric surgery. Post-procedure markers of obesity and cardiometabolic profile were monitored regularly for a year. RESULTS: Mean body mass index decreased by 29.5% from 41.9 to 29.5 kg/m2 between baseline and 12-mo follow-up, while mean fat mass decreased by 45.9% from 64.2 kg to 34.7 kg. An improvement was also observed in the gluco-metabolic profile with both fasting glucose and HbA1c substantially decreasing (P < 0.001). CONCLUSION: The present study shows the short to medium term (1 year) health benefits of bariatric surgery for patients of Middle Eastern ethnicity.

Metabolic improvement of morbid obese patients following Roux-en-Y gastric bypass surgery: A prospective study in Mashhad, Iran.

BACKGROUND AND AIM: Obesity is one of the greatest public health concerns worldwide. Weight loss surgeries have been increased in recent decades due to the world's epidemic of obesity. The aim of this prospective study is investigating metabolic factors of morbid obese patients following Roux-en-Y gastric bypass surgery. METHODS: This was a nonrandomized prospective cohort study conducted from 2010 to 2013 on 60 consecutive patients who had body mass index (BMI) of more than 40 kg/m(2) and met the surgical indication criteria of bariatric surgery. Upon discharge, patients were followed in outpatient clinic of Qaem Hospital, Mashhad, Iran, each 3 months for 12 months. Measurement of anthropometric and metabolic indices was done in each postoperative visit. RESULTS: Mean BMI reduction was 15.26 ± 3.45 kg/m(2) in the patients with an average value of 28.84 ± 3.94 (range from 22 to 40 kg/m(2)), which was significantly lower than the base value (p < 0.001). After a 12-month follow up, patients had lower low-density lipoprotein, triglycerides, and total cholesterol (p < 0.001 for all the variables), while achieving a greater high-density lipoprotein (p = 0.004). An improvement was seen in all of hypertensive patients after a 3-month follow up and blood pressure remained within normal limit in further follow ups. Complete remission was observed in all the patients with obstructive sleep apnea. CONCLUSION: It appears reasonable that multidisciplinary treatment including surgical alternatives should be concerned for all morbidly obese patients, considering high rate of failure of conservative medical therapy in this setting.

A clinical trial of neoadjuvant concurrent chemoradiotherapy followed by resection for esophageal carcinoma.

BACKGROUND: Esophageal carcinoma is a common malignancy in the North East of Iran. Combined modality treatments have been adopted to improve survival in patients with esophageal carcinoma. In this trial, we evaluated the efficacy and toxicity of a preoperative concurrent chemoradiotherapy protocol in the patients with locally advanced esophageal carcinoma. MATERIALS AND METHODS: Between 2006 and 2011, eligible patients with locally advanced esophageal carcinoma underwent concurrent radiotherapy and chemotherapy and 3-4 weeks later, esophagectomy. Pathologic response, overall survival rate, toxicity, and feasibility were evaluated. RESULTS: One hundred ninety-seven patients with a median age of 59 (range: 27-70) entered the protocol. One hundred ninety-four cases (98.5%) had esophageal squamous cell carcinoma. Grades 3-4 of toxicity in patients undergoing neoadjuvant chemoradotherapy were as follows: Neutropenia in 21% and esophagitis in 2.5% of cases. There were 11 (5.6%) early death probably due to the treatment-related toxicities. One hundred twenty-seven patients underwent surgery with postsurgical mortality of 11%. In these cases, the complete pathological response was shown in 38 cases (29.9%) with a 5-year overall survival rates of 48.2% and median overall survival of 44 months (95% confidence interval, 24.46-63.54). CONCLUSION: The pathological response rate and the overall survival rate are promising in patients who completed the protocol as receiving at least one cycle of chemotherapy. However, the treatment toxicities were relatively high.

Corrosive injury of the upper gastrointestinal tract: review of surgical management and outcome in 14 adult cases.

INTRODUCTION: Caustic ingestion is responsible for a spectrum of upper gastrointestinal tract injury from self-limited to perforation. This study conducted to evaluate clinical characteristics as well as surgical outcomes in patients with caustic ingestion. MATERIALS AND METHODS: Between Nov1993 to march 2011, 14 adults with a clinical evidence of corrosive ingestion were admitted into our institutions (Omid and Ghaem hospitals). Patients evaluated for etiology of erosion, location, type of surgery, morbidity and mortality after surgery. RESULTS: 14 patients (10men and 4 women) with a age range between18-53 years were evaluated. In 6 patients, the injury was accidental and in 8 patients ingestion was a suicide attempt. Ingested agent included nitric acid in 4 patients, hydrochloric acid in 7 patients, sulfuric acid in 2 patients and strong alkali in one patient. The location and extent of lesion varied included esophagus in 13 cases, stomach in 7 cases and the pharynx in 3 cases. Acute abdomen was developed In 2 patients and a procedure of total gasterectomy and blunt esophagectomy was performed. In the remaining patients, substernal esophageal bypass in 2 patients, esophageal resection and replacement surgery in 9 patients and gastroenterostomy in one patient performed to relieve esophageal stricture. Two patients died of mediastinitis after esophageal replacement surgery. Postoperative strictures were developed in 2 survived patients with hypopharyngeal reconstruction that was managed by per oral bougienage in one patient and KTP Laser and stenting in the other patient. CONCLUSION: Esophageal resection with replacement was safe and good technique for severe corrosive esophageal stricture with low mortality and morbidity.

Outcomes following surgery for complicated tuberculosis: analysis of 108 patients.

BACKGROUND: Both incidence and complications of pleuropulmonary tuberculosis (TB) have increased due to recent increase of immunocompromising conditions. The aim of this study was to assess surgical outcomes in patients suffering from complicated pleuropulmonary TB. METHODS: This study included 108 patients with pleuropulmonary TB who underwent surgery. Age, sex, surgical indications, operative techniques, complications, mortality, and morbidity were evaluated. RESULTS: Male-female ratio was 1:11 with mean age of 40 years; 72.2 and 27.8% of the patients underwent surgery due to parenchymal and pleural complications. In the parenchymal group, the most common indication was parenchymal destruction (27.7%) and the most common procedure was lobectomy (50.9%). Out of 20 sputum smear-positive patients, 15 had multidrug-resistant tuberculosis (MDR-TB) and 5 had smear-positive open cavity. Overall 13 of the MDR-TB group and all smear-positive open cavity group became sputum-negative after the surgery. There were 13 patients with undiagnosed masses, among whom 3 patients had adenocarcinoma. In the pleural group, the most common surgical indication was empyema (13.8%) and the most common procedure was decortication and pleurectomy (13.8%). In the bronchopleural fistula group (6.4%), patients showed good results after surgery. There were 19.4% of patients who showed postoperative complications. The most common complication was residual space (5.5%). The main factors leading to major postoperative complications included positive preoperative sputum smear and history of immunocompromising condition. Mortality rate was 2.7%. CONCLUSION: Considering the favorable results achieved by surgery in patients with pleuropulmonary TB, this treatment can be recommended for this group of patients.
