Prior studies have shown improvement in memory, executive function and attention, after Roux-en-Y gastric bypass (RYGB) operation in the Western population. However, there is a scarcity of data on cognitive improvement following BS in a non-Western population. Objective: The objective of the study is to evaluate changes in cognitive functions of patients with severe obesity, after BS. Study Setting: Tertiary-care Academic Center, India. Methodology: A prospective study of patients undergoing BS was conducted. Specific neurocognitive tests (Mini-mental Status Examination, Standard progressive matrices, Controlled Oral Word Association Test, and Post Graduate Institute Memory Scale test) were used to assess cognitive status at baseline (preoperatively), and at 3, 6, and 12 months. Results: Fifty-three patients were enrolled in the study, out of which 50 had completed 1 year of follow-up at the time of analysis (n = 50). Thirty-six patients (72%) were females. The median age was 42 years, and the mean preoperative body mass index (BMI) was 45.5 ± 6.3 kg/m2. 40 patients underwent SG, while 10 underwent RYGB procedure. At baseline, the study cohort had impairment of abstract reasoning, attention, and verbal retention, as compared to normative data. At 1 year after surgery, the mean BMI was 29.1 ± 2.6 kg/m2. There was a significant (P < 0.05) improvement in most cognitive domains (global cognitive functioning, abstract reasoning, attention/concentration, and memory function). However, improvement in language function was not found to be significant across the follow-up duration of 12 months (P = 0.35). Conclusions: Individuals with severe obesity experience baseline impairment in cognitive functions. Similar to results from the Western population, BS (RYGB and SG) results in a significant improvement in multiple cognitive domains even in a non-Western population.","PeriodicalId":73828,"journal":{"name":"Journal of metabolic and bariatric surgery","volume":"9 1","pages":"82 - 87"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88815401","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}

We studied the hemodynamic changes during pneumoperitoneum and reverse Trendelenburg position in bariatric surgery, using noninvasive cardiac output (CO) monitoring. Methods: In this prospective observational study, 60 patients of the American Society of Anesthesiologists Grade I–II, aged between 18 and 60 years, planned for elective laparoscopic bariatric surgery were included. During the intraoperative period, hemodynamic monitoring was done using an estimated continuous CO (esCCO) monitor. We noted oxygen saturation (SpO2), heart rate, blood pressure (BP), and CO values obtained before induction of general anesthesia and were compared with values obtained after induction, postintubation, after pneumoperitoneum, after reverse Trendelenburg, and every 10 min during the procedure and postextubation. Results: The mean baseline SpO2, pulse rate (PR), systolic BP (SBP), diastolic BP (DBP), and CO was 99.17 ± 1.7, 99.9 ± 1.35 bpm, 136.3 ± 14.5 mm Hg, 83.11 ± 10.5 mm Hg, and 7.59 ± 1.44 L/min, respectively.

Although this concern is universal among bariatric surgeons, strategies to prevent complications related to the staple line are not consensual. Accordingly, staple-line reinforcement methods have been widely proposed in an attempt to reduce the risk of these adverse events. However, nonreinforced but technically well-performed staple line can also be a very safe option, saving operative time and procedure-related costs.
