Gastrointestinal reported outcomes following one anastomosis gastric bypass based on a multicenter study.

OBJECTIVES: To describe gastrointestinal-related side-effects reported following the One Anastomosis Gastric Bypass (OAGB). METHODS: A multicenter study among OAGB patients across Israel (n = 277) and Portugal (n = 111) who were recruited to the study based on time elapsed since surgery was performed. An online survey with information on demographics, anthropometrics, medical conditions, and gastrointestinal outcomes was administered in both countries simultaneously. RESULTS: Respondents from Israel (pre-surgery age of 41.6 ± 11.0 years, 75.8% females) and Portugal (pre-surgery age of 45.6 ± 12.3 years, 79.3% females) presented mean excess weight loss of 51.0 ± 19.9 and 62.4 ± 26.5%, 89.0 ± 22.0 and 86.2 ± 21.4%, and 89.9 ± 23.6 and 98.2 ± 20.9% (P < 0.001 for both countries), at 1-6 months, 6-12 months, and 1-5 years post-surgery, respectively. Median Gastrointestinal Symptom Rating Scale score was similar between time elapsed since surgery groups among respondents from Israel and Portugal (≤1.97 and ≤2.12). A notable proportion of respondents from Israel and Portugal at all time points reported 1-3 bowel movements per day (≤62.8 and ≤87.6%), Bristol stool scale categories which represent diarrhea-like stools (≤51.9 and ≤56.3%), having discomfort due to flatulence (≤79.4 and ≤90.2%), and mild to severe dyspepsia symptoms (≤50.5 and ≤73.0%). CONCLUSIONS: A notable proportion of OAGB patients might experience certain gastrointestinal symptoms postoperatively, including flatulence, dyspepsia, and diarrhea-like stools.

Nutritional and Lifestyle Behaviors Reported Following One Anastomosis Gastric Bypass Based on a Multicenter Study.

This study aimed to describe nutritional and lifestyle parameters following one-anastomosis gastric bypass (OAGB). A multicenter study among OAGB patients across Israel (n = 277) and Portugal (n = 111) was performed. Patients were approached according to the time elapsed since surgery. An online survey with information regarding demographics, anthropometrics, and nutritional and lifestyle aspects was administered in both countries simultaneously. Respondents from Israel (pre-surgery age of 41.6 ± 11.0 years, 75.8% females) and Portugal (pre-surgery age of 45.6 ± 12.3 years, 79.3% females) reported changes in their appetite (≤94.0% and ≤94.6%), changes in their taste (≤51.0 and ≤51.4%), and intolerance to specific foods (i.e., red meat, pasta, bread, and rice). Bariatric surgery-related eating recommendations were generally followed well, but a trend toward lower adherence was evident in groups with longer time elapsed since surgery in both countries. Most respondents from Israel and Portugal reported participation in follow-up meetings with a surgeon (≤94.0% and 100%) and a dietitian (≤92.6% and ≤100%), while far fewer reported participation in any follow-up meeting with a psychologist/social worker (≤37.9% and ≤56.1%). Patients following OAGB might experience changes in appetite, taste, and intolerance to specific foods. Adherence to bariatric surgery-related eating recommendations is not always satisfying, especially in the longer term post-surgery.

Long-Term Matched Comparison of Primary and Revisional Laparoscopic Sleeve Gastrectomy.

BACKGROUND: Reports of long-term (> 5-15-year) outcomes assessing the safety and efficacy of primary revisional laparoscopic sleeve gastrectomy (LSG) are few. METHODS: Retrospective long-term comparisons of primary (pLSG) and revisional (rLSG) procedures were matched for gender, age ± 5 years, and body mass index (BMI) ± 5 kg/m2. Weight loss, associated medical condition status, and patient satisfaction were evaluated. RESULTS: Between May 1, 2006, and December 31, 2016, 194 matched patients with severe obesity (mean BMI 44.1 ± 6.7 kg/m2; age 44.2 ± 10.0 years, 67.0% female) underwent pLSG (n = 97) or rLSG (n = 97) and were followed for a mean 12.1 ± 1.5 vs 7.6 ± 2.1 years. Respective mean weight regain from nadir was 15.0 ± 14.4 kg vs 11.9 ± 12.2 kg. Respective percent mean total weight loss and excess weight loss were 20.9 ± 12.7% and 51.8 ± 33.1%, and 18.3 ± 12.8% and 43.4 ± 31.6% at last follow-up, with no significant difference between groups. Resolution of type 2 diabetes (HbA1C < 6.5%, off medications) was 23.1% vs 11.1%; hypertension 36.0% vs 16.0%; and hyperlipidemia 37.1% vs 35.3%. Patients in the pLSG group were significantly more satisfied with LSG (59.8% vs 43.3%, p < 0.05) and more likely to choose the procedure again. CONCLUSIONS: There were no significant differences in long-term weight loss or associated medical condition outcomes in matched pLSG and rLSG patients.

Long-term Reported Outcomes Following Primary Laparoscopic Sleeve Gastrectomy.

BACKGROUND: Long-term laparoscopic sleeve gastrectomy (LSG) outcomes in patients with obesity are scarce. We aimed to examine the outcomes and subjective experience of patients who underwent primary LSG with long-term follow-up. METHODS: The study is a retrospective observational analysis of patients who underwent primary LSG in a single center with 5-15 years of follow-up. Patients' hospital chart data supplemented by a detailed follow-up online questionnaire and telephone interview were evaluated. RESULTS: The study sample included 578 patients (67.0% female) with 8.8 ± 2.5 years of mean follow-up, with a response rate to the survey of 82.8%. Mean baseline age and body mass index (BMI) were 41.9 ± 10.6 years and 42.5 ± 5.5 kg/m2, respectively. BMI at nadir was 27.5 ± 4.9 kg/m2, corresponding to a mean excess weight loss (EWL) of 86.9 ± 22.8%. Proportion of patients with weight regain, defined as nadir ≥ 50.0% EWL, but at follow-up < 50.0% EWL, was 34.6% (n = 200) and the mean weight regain from nadir was 13.3 ± 11.1 kg. BMI and EWL at follow-up were 32.6 ± 6.4 kg/m2 and 58.9 ± 30.1%, respectively. The main reasons for weight regain given by patients included "not following guidelines," "lack of exercise," "subjective impression of being able to ingest larger quantities of food in a meal," and "not meeting with the dietitian." Resolution of obesity-related conditions at follow-up was reported for hypertension (51.7%), dyslipidemia (58.1%) and type 2 diabetes (72.2%). The majority of patients (62.3%) reported satisfaction with LSG. CONCLUSIONS: In the long term, primary LSG was associated with satisfactory weight and health outcomes. However, weight regain was notable.

Does admission hypothermia predispose to intraventricular hemorrhage in very-low-birth-weight infants?

BACKGROUND: The etiology of intraventricular hemorrhage (IVH) in very-low-birth-weight (VLBW) infants is multifactorial and is associated with low gestational age (GA) and severity of neonatal respiratory disease. The role of admission hypothermia (AHT) in the pathogenesis of IVH in VLBW infants has not yet been elucidated. We searched risk factors for IVH in VLBW infants while focusing on AHT. PATIENTS AND METHODS: VLBW infants ≤33 weeks' gestation from three participating medical centers were included. From patients' medical charts we collected variables known to be associated with IVH, focusing on AHT. AHT was defined as rectal temperature ≤35.5°C at admission to the NICU. Head ultrasound was performed at 2-5 and 6-10 days of age and before discharge. RESULTS: 271 VLBW infants were studied. Univariate analysis showed that AHT at ≤35.5°C was not significantly associated with IVH (all grades; p = 0.16), but associated with IVH grade 3-4 (p = 0.034), while AHT at ≤35°C was significantly associated with IVH (p = 0.036) and with IVH grade 3-4 (p = 0.003). Multivariate logistic regression analysis showed that AHT (at ≤35.5 and at ≤35°C) were not associated with IVH. Only four variables were independently significantly associated with IVH: GA, use of nitric oxide, hypocarbia and base deficit >10. Four variables were strongly associated with severe IVH (grades 3-4): GA, hypotension, base deficit >10 and hyponatremia. CONCLUSIONS: In VLBW infants, AHT at ≤35.5 and at ≤35.0°C were not significantly associated with IVH. GA, use of nitric oxide, hypocarbia and base deficit >10 were strongly associated with IVH.
