Peer Review Report
Peer review report 1 on “Laparoscopic sleeve gastrectomy versus laparoscopic mini gastric bypass: One year outcomes of a retrospective study”
1. Original submission 1.1. Recommendation Reject.
4. What is the duration of hypertension and what is the clear definition of remission and improvement. 5. What is criteria of improvement of osteoarthritis 6. What is the type of complication related to gastrointestinal imaging on day 2 postoperative to allow patients to drink or not. 7. What is the parameters to test the nutritional and micronutrient deficiency
1.2. Comments to the author All bariatric surgery procedures are disturbing the anatomy except the sleeve gastrectomy. Safety, efficacy, easy to done and less complication are the items which push us to select it for our patients. Studies comparing outcomes between LSG and LMGB are scarce. This is very good idea to start we have study as this because MGB is emerging nowadays. But the authors didn't answer the target question that why the MGB is superior to the sleeve gastrectomy via the results and explanation of the hypothesis in the discussion. 1.2.1. Title I think you must add to it (Retrospective cohort study). 1.2.2. Introduction The concept of restrictive procedures for MGB is not true, MGB is act by entero-hormonal effect and if you increase the length of billiopancreatic limb will act also as malabsorption concept. we don't care about the size of gastric pouch or the size of gastrojejenal anastomosis, our care only is the length of the pouch. so you must change this concept from the introduction. 1.2.3. Material and methods 1. In MGB, no data about the length of gastric pouch, diameter of gastrojejenostomy and which school the author re follow, Rutledge's school or Carbajo caballero's school. 2. In sleeve gastrectomy, what is the type of stapler, colour of cartilage used. 3. As regards the diabetes, what is duration of diabetes, what is the criteria of remission and improvement, which type of diabetes (type one or two) , what is about HbA1c and C-peptide. DOI of published article: http://dx.doi.org/10.1016/j.ijsu.2016.07.051. http://dx.doi.org/10.1016/j.ijsu.2016.11.103 1743-9191
1.2.4. Results 1. Cases with leak, what is the tool for diagnosis, what is the strategies of authors to treat it and what is the results 2. Cases with stenosis, what is the tool for diagnosis, what is the strategies of authors to treat it and what is the results 3. What is mean by improvement of diabetes, it mean the remission and who has decrease of drug used. it must be separate and which is percentage of each one. 4. No data about reflex esophagitis or biliary reflux 5. No data about nutritional deficiency 6. The data of bleeding is illusion, what is the criteria and what is the tool to diagnose it, need transfusion, change in HB, just increase of rate of pulse or large amount from the drain, shock, haematemesis or need exploration
1.2.5. Discussion 1. No explanation of high incidence of stenosis or leak 2. In page 9, the authors said that malabsorption effect of MGB is the cause of good lose of weight, but the cornerstone of MGB is modulation of intestinal hormones not malabsorption. 3. In page 10, authors discussed the malnutrition after MGB and he didn't have any data about it. 4. Nodata for discussion about hypoalbuminemia, iron deficiency anaemia, vitamin b1 or b12 deficiency or other micronutrient. 5. The authors avoid to compare the most important items for comparisons as reflux, hypoalbuminemia, iron deficiency 6. Unclear definition of remission and improvement in diabetes and hypertension
