Early safety outcomes of laparoscopic one anastomosis gastric bypass in patients with class III, IV, and V obesity. World J Surg 2024. [PMID: 38593247 DOI: 10.1002/wjs.12182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Accepted: 03/30/2024] [Indexed: 04/11/2024]
Abstract
BACKGROUND The extremely obese patient deserves special consideration: significant comorbidities, technical difficulties, and increased postoperative morbidity and mortality are all expected in this patient population. The study compared early postoperative complications (≤30-day) following one-anastomosis gastric bypass (OAGB) morbidity in patients with morbid obesity class IV obesity, body mass index (BMI) ≥50-59.9 kg/m2, and class V obesity, BMI ≥60 patients. METHODS We retrospectively reviewed perioperative OAGB outcomes in three BMI groups. Operative time, length of stay (LOS), and overall early postoperative complication rates were studied. Patient-reported complications were ranked by Clavien-Dindo Classification (CDC). RESULTS Between January 2017-December 2021, consecutive patients with obesity class III (n = 2950), IV (n = 256), and V (n = 23) underwent OAGB. BMI groups were comparable in sex, age, and associated comorbidities. Mean operative time was significantly longer in the higher BMI groups: class III (66.5 ± 25.6 min), IV (70.5 ± 28.7 min), and V (80.0 ± 34.7 min), respectively (p = 0.018); no difference in LOS. In respective BMI classes, ≤30-day complication rates were 3.2%, 3.5%, and 4.3% (p = 0.926). The respective number of patients with CDC grades of one to two were 45 (1.5%), 6 (2.3%), and 1 (4.3%), p = 0.500; and in grade ≥3a, 25 (0.8%), 1 (0.4%), 0 (0.0%), p = 0.669. There was 0.06% mortality (n = 2 in 3229), both in BMI class III. CONCLUSIONS OAGB is a safe BS procedure in patients with class III, IV, and V obesity in the perioperative term with comparable ≤30-day morbidity in the three BMI groups.

Early outcomes of one-anastomosis gastric bypass in the elderly population at high-volume bariatric centers. Updates Surg 2024; 76:187-191. [PMID: 38012431 DOI: 10.1007/s13304-023-01697-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 11/03/2023] [Indexed: 11/29/2023]
Abstract
The increasing rate of obesity and life expectancy will lead to increasing numbers of bariatric procedures in the elderly. We aim to report the early (≤ 30 days) adverse events of One-Anastomosis Gastric Bypass (OAGB) in this patient population. Assuta Bariatric Centers in Israel. Retrospective review of perioperative OAGB outcomes between elderly group (≥ 65 years) and non-elderly group (18-64 years) at high-volume bariatric centers between January 2017-December 2021. Operative time, length of stay (LOS), and overall ≤ 30 days complication rates, as ranked by the Clavien-Dindo Classification (CDC) were compared. There were 6618 patients (non-elderly group) and 104 (elderly group) who underwent OAGB. Gender and preoperative BMI were comparable between the two age groups. The elderly group had significantly higher rate of ischemic heart disease and chronic renal failure. The number of patients with LOS ≥ 3 days was significantly higher in the elderly group [19.4% (n = 20) vs. 6.6% (n = 331), respectively; p < 0.001]. The total early adverse events were higher in the elderly group with no statistical significance [7.7% (n = 8) vs. 3.8% (n = 250), respectively; p = 0.062]. The rate of minor and major adverse events and reoperation rate was comparable between the two groups. The rate of readmissions was significantly higher in the elderly group 5.8% (n = 6) vs. 1.9% (n = 124), respectively p = 0.015. There was 0.06% mortality (n = 2) in the non-elderly group. OAGB is a relatively safe metabolic and bariatric surgery for elderly obese patients with early (≤ 30 days) morbidity rates similar to the non-elderly population.

One Anastomosis Gastric Bypass in 6722 Patients: Early Outcomes from a Private Hospital Registry. J Clin Med 2023; 12:6872. [PMID: 37959337 PMCID: PMC10648472 DOI: 10.3390/jcm12216872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 10/16/2023] [Accepted: 10/26/2023] [Indexed: 11/15/2023] Open
Abstract
BACKGROUND One-anastomosis gastric bypass (OAGB) is an emerging metabolic bariatric surgery (MBS) type used in both primary OAGB (pOAGB) and revisional OAGB (rOAGB). We studied ≤30-day outcomes of pOAGB and rOAGB and identified predictors of early complications. METHODS Electronic medical records of all OAGBs performed between January 2017 and December 2021 at a high-volume bariatric clinic in Israel comprising four hospital centers were scanned retrospectively using specialized data software (MDClone software, version 6.1). Data gathered were patients' characteristics, surgical procedure, and ≤30-day complications with Clavien-Dindo Classification (CDC). Multivariate logistic regression analyses were used to identify factors related to early complications of pOAGB and rOAGB. RESULTS A total of 6722 patients underwent a pOAGB (n = 5088, 75.7%) or rOAGB (n = 1634, 24.3%) procedure at our institution. Preoperative mean age and body mass index (BMI) were 40.6 ± 11.5 years and 41.2 ± 4.6 kg/m2, respectively. Early complications occurred in 258 (3.8%) patients (176 pOAGB and 82 rOAGB) and included mainly bleeding (n = 133, 2.0%), leaks (n = 31, 0.5%), and obstruction/strictures (n = 19, 0.3%). CDC complications for grades 1-2 and grades 3a--5 were 1.5% and 1.6%, respectively. The overall mortality rate was 0.03% (n = 2). Age, operative time ≥3 h, and any additional concomitant procedure were independent predictors of early complications following pOAGB, while a diagnosis of diabetes mellitus and operative time ≥3 h were independent predictors of early complications following rOAGB. CONCLUSIONS OAGB was found to be a safe primary and revisional MBS procedure in the ≤30-postoperative day term. The most common complications were gastrointestinal bleeding, leaks, and obstruction/stricture.

Abstract
OBJECTIVES To describe gastrointestinal-related side-effects reported following 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. Nutrients 2023; 15:nu15061515. [PMID: 36986245 PMCID: PMC10053792 DOI: 10.3390/nu15061515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Revised: 03/13/2023] [Accepted: 03/15/2023] [Indexed: 03/30/2023] Open
Abstract
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.

P-353 Placenta previa in In Vitro Fertilization and unassisted pregnancies – is there a difference in perinatal outcomes and placental histology? Hum Reprod 2022.

Abstract
Abstract
Study question
Why is In-vitro-fertilization (IVF) an independent risk factor for placenta previa (PP).
Summary answer
While PP in non-assisted pregnancies is probably associated with previous cesarean deliveries (CD), in IVF it is more “sporadic”, and may complicate any index pregnancy.
What is known already
PP is more prevalent following IVF pregnancies as compared with unassisted pregnancies, with an increased risk of three to six-fold according to some authors. The etiology for this increased risk in IVF pregnancies in unclear, and may be related to reproductive procedures performed or to subfertility characteristics which have led to IVF.
Study design, size, duration
A retrospective-cohort study of deliveries with PP between 2008 and 2021. A total of 182 pregnancies were included.
Participants/materials, setting, methods
Placental histopathology, obstetric and neonatal outcomes were compared between IVF and unassisted pregnancies. Included, were singleton deliveries complicated by PP at gestational weeks (GA)> 24. Placental pathology was obtained utilizing the well-accepted Amsterdam criteria.
Main results and the role of chance
Out of 182 pregnancies which were included - 23 IVF pregnancies (IVF group) and 159 in the unassisted pregnancies (Control group). The control group was characterized by higher gravidity (p = 0.007) and parity (p < 0.001), whereas the IVF group- by a higher rate of nulliparity (p < 0.001) and diabetes mellitus (p = 0.04). A higher rate of patients with past CDs was noted in unassisted pregnancies, although not statistically significance (38.9% versus 21.7%, p = 0.10). There was a trend for a lower placental weight in the control group, and a higher incidence of placental weight below the 10thpercentile in this group (47.8% versus 13.9%, p = 0.001). No differences were noted in maternal and fetal vascular lesions. Nevertheless, IVF and unassisted pregnancies entail similar perinatal outcomes in cases of PP.
Limitations, reasons for caution
A major limitation was our small sample size in the IVF group. Despite a power calculation, larger study groups would have possibly allowed for the demonstration of additional differences in outcomes, including previous cesarean deliveries and placenta accreta. Moreover, this limitation prevented us from matching against possible cofounders.
Wider implications of the findings
While a growing proportion of pregnancies worldwide are conceived by IVF, possible iatrogenic side effects should be studied. As PP is of clinical importance, it is essential to diagnose it on time, as well as study the mechanisms and risk factors behind it, which could possibly help with its prevention.

The Effects of One Anastomosis Gastric Bypass Surgery on the Gastrointestinal Tract. Nutrients 2022; 14:nu14020304. [PMID: 35057486 PMCID: PMC8778673 DOI: 10.3390/nu14020304] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Revised: 12/28/2021] [Accepted: 01/06/2022] [Indexed: 02/05/2023] Open
Abstract
One anastomosis gastric bypass (OAGB) is an emerging bariatric procedure, yet data on its effect on the gastrointestinal tract are lacking. This study sought to evaluate the incidence of small-intestinal bacterial overgrowth (SIBO) following OAGB; explore its effect on nutritional, gastrointestinal, and weight outcomes; and assess post-OABG occurrence of pancreatic exocrine insufficiency (PEI) and altered gut microbiota composition. A prospective pilot cohort study of patients who underwent primary-OAGB surgery is here reported. The pre-surgical and 6-months-post-surgery measurements included anthropometrics, glucose breath-tests, biochemical tests, gastrointestinal symptoms, quality-of-life, dietary intake, and fecal sample collection. Thirty-two patients (50% females, 44.5 ± 12.3 years) participated in this study, and 29 attended the 6-month follow-up visit. The mean excess weight loss at 6 months post-OAGB was 67.8 ± 21.2%. The glucose breath-test was negative in all pre-surgery and positive in 37.0% at 6 months (p = 0.004). Positive glucose breath-test was associated with lower reported dietary intake and folate levels and higher vitamin A deficiency rates (p ≤ 0.036). Fecal elastase-1 test (FE1) was negative for all pre-surgery and positive in 26.1% at 6 months (p = 0.500). Both alpha and beta diversity decreased at 6 months post-surgery compared to pre-surgery (p ≤ 0.026). Relatively high incidences of SIBO and PEI were observed at 6 months post-OAGB, which may explain some gastrointestinal symptoms and nutritional deficiencies.

The Effect of an Education Module to Reduce Weight Bias among Medical Centers Employees: A Randomized Controlled Trial. Obes Facts 2022; 15:384-394. [PMID: 35066508 PMCID: PMC9210013 DOI: 10.1159/000521856] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Accepted: 01/06/2022] [Indexed: 11/19/2022] Open
Abstract
INTRODUCTION Weight bias, stigma, and discrimination are common among healthcare professionals. We aimed to evaluate whether an online education module affects weight bias and knowledge about obesity in a private medical center setting. METHODS An open-label randomized controlled trial was conducted among all employees of a chain of private medical centers in Israel (n = 3,290). Employees who confirmed their consent to participate in the study were randomized into intervention or control (i.e., "no intervention") arms. The study intervention was an online 15-min educational module that included obesity, weight bias, stigma, and discrimination information. Questionnaires on Anti-Fat Attitudes (AFA), fat-phobia scale (F-scale), and beliefs about the causes of obesity were answered at baseline (i.e., right before the intervention), 7 days, and 30 days post-intervention. RESULTS A total of 506, 230, and 145 employees responded to the baseline, 7-day, and 30-day post-intervention questionnaires, respectively. Mean participant age was 43.3 ± 11.6 years, 84.6% were women, and 67.4% held an academic degree. Mean F-scale scores and percentage of participants with above-average fat-phobic attitudes (≥3.6) significantly decreased only within the intervention group over time (p ≤ 0.042). However, no significant differences between groups over time were observed for AFA scores or factors beliefs to cause obesity. CONCLUSIONS A single exposure to an online education module on weight bias and knowledge about obesity may confer only a modest short-term improvement in medical center employees' fat-phobic attitudes toward people with obesity. Future studies should examine if reexposure to such intervention could impact weight bias, stigma, and discrimination among medical center staff in the long-term.

30-Day Morbidity and Mortality of Bariatric Surgery During the COVID-19 Pandemic: a Multinational Cohort Study of 7704 Patients from 42 Countries. Obes Surg 2021; 31:4272-4288. [PMID: 34328624 PMCID: PMC8323543 DOI: 10.1007/s11695-021-05493-9] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 05/14/2021] [Accepted: 05/20/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND There are data on the safety of cancer surgery and the efficacy of preventive strategies on the prevention of postoperative symptomatic COVID-19 in these patients. But there is little such data for any elective surgery. The main objectives of this study were to examine the safety of bariatric surgery (BS) during the coronavirus disease 2019 (COVID-19) pandemic and to determine the efficacy of perioperative COVID-19 protective strategies on postoperative symptomatic COVID-19 rates. METHODS We conducted an international cohort study to determine all-cause and COVID-19-specific 30-day morbidity and mortality of BS performed between 01/05/2020 and 31/10/2020. RESULTS Four hundred ninety-nine surgeons from 185 centres in 42 countries provided data on 7704 patients. Elective primary BS (n = 7084) was associated with a 30-day morbidity of 6.76% (n = 479) and a 30-day mortality of 0.14% (n = 10). Emergency BS, revisional BS, insulin-treated type 2 diabetes, and untreated obstructive sleep apnoea were associated with increased complications on multivariable analysis. Forty-three patients developed symptomatic COVID-19 postoperatively, with a higher risk in non-whites. Preoperative self-isolation, preoperative testing for SARS-CoV-2, and surgery in institutions not concurrently treating COVID-19 patients did not reduce the incidence of postoperative COVID-19. Postoperative symptomatic COVID-19 was more likely if the surgery was performed during a COVID-19 peak in that country. CONCLUSIONS BS can be performed safely during the COVID-19 pandemic with appropriate perioperative protocols. There was no relationship between preoperative testing for COVID-19 and self-isolation with symptomatic postoperative COVID-19. The risk of postoperative COVID-19 risk was greater in non-whites or if BS was performed during a local peak.

P–395 Obstetric and perinatal outcomes of pregnancies resulting from fresh versus frozen embryo transfer – a sibling cohort. Hum Reprod 2021.

Abstract
Abstract
Study question
We aimed to compare obstetric and perinatal outcomes between pregnancies conceived by in vitro fertilization (IVF) with fresh embryo transfer and frozen embryo transfer (FET) in the same women.
Summary answer
IVF pregnancies following fresh and FET entailed the same obstetric and perinatal outcomes, when compared in the same women. What is known already: There seems to be a difference in adverse outcomes between pregnancies following fresh and FET, as fresh transfer has repeatedly been associated with a higher risk of preterm birth and small for gestational age neonates, and the FET with preeclampsia and large for gestational age neonates. The overall lower incidence of adverse obstetric outcomes in FET may relate to the transfer of an embryo to a uterine environment in the setting of more physiological estradiol level but may also relate to patient characteristics which allow for freezing and subsequent transfer.
Study design, size, duration
This was a retrospective cohort of 214 deliveries during a 13-year period.
Participants/materials, setting, methods
The study was performed in a tertiary hospital. The cohort included live singleton deliveries (>24 weeks of gestation) and excluded pregnancies following egg donation. Each fresh transfer IVF pregnancy was matched to a FET pregnancy by the same woman (1:1 ratio).
Main results and the role of chance
A total of 107 fresh transfer pregnancies were matched to 107 FET pregnancies, in the same women. Mean maternal age was lower in the fresh transfer group compared to the FET group (30.4 vs. 32.5 years, p < 0.001), as was body mass index (BMI) (p = 0.001). A higher rate of nulliparity was noted in fresh transfer pregnancies (64.5% vs. 12.1%, p < 0.001). Mean birthweight was higher in the FET group (3160 vs. 3081 grams, respectively, p < 0.001), although the rates of low birth weight and small for gestational age neonates did not differ between the groups. Preterm deliveries occurred in 10.3% and 9.3% of fresh transfer and FET pregnancies respectively, p = 0.79. On multivariate linear regression analysis, the type of embryo transfer - FET or fresh - was not independently associated with birthweight, after adjustment for women’s age, nulliparity and BMI.
Limitations, reasons for caution
The study relied on coding in patient files, and thus certain data were missing for analysis, such as paternal identity. In addition, women included had at least two successful IVF pregnancies, and at least one cycle in which embryo freezing was performed. This may confer a selection bias.
Wider implications of the findings: Our study of sibling deliveries after fresh and FET, points to a similar prognosis for the main obstetric and perinatal outcomes. This adds to current research which points to similar development of children following fresh and FET and is reassuring for clinicians consulting patients who are eligible for both options.

Abstract
Abstract
Study question
Should women receive luteal phase support (LPS) following natural cycle frozen embryo transfer (NC-FET)?
Summary answer
Progesterone LPS following NC-FET increases the live birth rate. There is no evidence to support the administration of hCG for LPS in these cases.
What is known already
Whether or not women should receive LPS following NC-FET is highly controversial. Previous studies have shown conflicting results.
Study design, size, duration
We conducted a systematic search of the literature published in Medline/PubMed, Embase and the Cochrane Library, from January 2000 until December 2020. We included all original English, peer-reviewed articles, irrespective of study-design. The search strategy included keywords related to natural cycle frozen embryo transfer and luteal phase support. Studies reporting the results of artificial or stimulated FET cycles were excluded.
Participants/materials, setting, methods
Our systematic search generated 395 records. After screening, eight studies were included in the review and seven studies were included in the meta-analysis. Two studies (n = 858) used hCG, and 6 studies (n = 1507) used progesterone for luteal support. Four studies were randomized controlled trials (RCTs), whereas the other four were historic cohort studies.
Main results and the role of chance
In a meta-analysis using random effects model, hCG administration for LPS did not increase the clinical pregnancy rate (two studies, OR 0.85, 95% CI 0.64–1.14). On the other hand, progesterone LPS was associated with a higher clinical pregnancy rate (five studies, OR 1.48, 95% CI 1.14–1.94), and a higher live birth rate (three studies, OR 1.67, 95% CI 1.19–2.36).
Limitations, reasons for caution
There was large heterogeneity in progesterone dose and route of administration, as well as the methods used for ovulation detection and triggering. Moreover, only four studies were randomized. Finally, both studies examining the use of hCG for LPS were performed by the same group of researchers in a single center.
Wider implications of the findings: The available evidence indicates that progesterone administration for LPS is beneficial following natural cycle frozen embryo transfer. There is no evidence to support the administration of hCG for LPS in these cases. Additional Large RCTs are necessary in order to improve the quality of evidence and validate our findings.

Health Status, Eating, and Lifestyle Habits in the Long Term Following Sleeve Gastrectomy. Obes Surg 2021; 31:2979-2987. [PMID: 33829384 DOI: 10.1007/s11695-021-05336-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 02/27/2021] [Accepted: 03/04/2021] [Indexed: 12/13/2022]
Abstract
INTRODUCTION Sleeve gastrectomy (SG) is an established bariatric procedure. However, long-term data on eating and lifestyle behaviors and their effect on weight outcomes are scarce. Therefore, this study aimed to examine these long-term behaviors and their associations to weight outcomes following SG. METHODS A long-term follow-up study (>5 years post-surgery) of 266 adult patients admitted to a primary SG surgery during 2008-2012 and who participated in a pre-surgery study was conducted. Data on pre-surgery demographics, anthropometrics, and medical status were obtained from the patients' medical records. Data on long-term health status, anthropometrics, lifestyle and eating habits, eating pathologies, follow-up regime, and satisfaction from the surgery were collected by an interview phone calls according to a structured questionnaire. RESULTS Data of 169 patients were available before and 7.8±1.0 years post-SG. Their baseline mean age was 41.8±11.3 years, and 71.6% of them were females. The mean post-surgery excess weight loss (EWL) was 53.2±31.2%, and 54.2% had EWL of ≥50%. Eating 3-6 meals per day, not having the urge to eat after dinner, separating liquids from solids, avoiding carbonated beverages, and performing physical activity were related to better weight-loss outcomes (P≤0.026). However, frequent need for eating sweets, binge eating, and feeling guilty or sad after eating were related to worse weight-loss outcomes (P≤0.010). Furthermore, only a minority reported taking a multivitamin and participating in follow-up meetings after more than 1 year since the surgery (≤21.3%). CONCLUSIONS In the long term following SG, approximately half achieved EWL of ≥50%, and physical activity, certain eating patterns, and eating pathologies were related to weight outcomes.

Assessing Bleeding Risk in Bariatric Surgeries: A Retrospective Analysis Study. Dig Dis 2020; 38:449-457. [PMID: 32053819 DOI: 10.1159/000506456] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Accepted: 02/12/2020] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To determine the factors that influence bleeding during the course of bariatric surgeries. BACKGROUND Bariatric surgery is safe with a low percentage of complications compared with other abdominal surgeries. Bleeding is one of the most common complications in surgery for obesity that has the risk of being catastrophic. METHODS The study includes 8,544 cases that underwent bariatric surgery from January 2013 to March 2016 retrospectively, in 4 private institutions. Multiple demographic data were collected: patient characteristics, diseases, medications, surgery type, operative technique, devices, surgeon's skill, and volume. RESULTS Bleeding was the most frequent complication that occurred in 122 (1.3%) patients. The Gastric bypass had the highest rate of bleeding (3.05%) of which, 20% were intraoperative bleeding and 80% postoperatively (intra-abdominal in 75%, and intra-luminal in 5%). Simultaneous surgeries, revisional surgeries, stratification of body mass index, stapler line reinforcement, and hospital volume did not affect bleeding occurrence. The determining factors for bleeding were hypertension, chronic lung disease, age >45 years, arrhythmia, and surgeon's skills. CONCLUSION Bleeding after bariatric surgery has a low occurrence. The factors that influence the occurrence of perioperative bleeding in bariatric surgery are: hypertension, chronic lung disease, age >45 years, arrhythmia, and surgeon's skills.

Associations of dietitian follow-up counselling visits and physical exercise with weight loss one year after sleeve gastrectomy. Eat Weight Disord 2020; 25:143-150. [PMID: 29987777 DOI: 10.1007/s40519-018-0531-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2018] [Accepted: 06/18/2018] [Indexed: 01/09/2023] Open
Abstract
PURPOSE To examine associations of patients' attendance to follow-up meetings with a registered dietitian (RD) and physical exercise practices with weight loss during the 1 year following laparoscopic sleeve gastrectomy (SG). METHODS Of 241 patients with obesity who underwent SG during 2012, 184 (76.3%) participated in a 1-year follow-up telephone interview and had information on number of RD follow-up meetings. Clinical information was available from computerized patient files. Multiple logistic regression analysis, adjusting for propensity score, was computed to reveal factors associated with greater weight loss. RESULTS The mean %TWL was 31.4 ± 6.1 and the mean number of reported RD meetings during the year following SG was 4.6. The proportion of physically active patients increased by 15% (from 23 to 42) among those who attended at least 3 RD follow-up meetings (n = 123), and by 5% (from 18 to 23) among those who attended fewer than 3 meetings (n = 61) (p = 0.05). Patients conducting physical exercise reported a lower level of pain/discomfort on the EQ5D quality-of-life questionnaire (p = 0.03). The adjusted regression model revealed no association between the number of RD follow-up meetings and weight-reduction success, but physical exercise during the year following SG conferred a 2.6 times greater odds of belonging to the upper two tertiles of the % excess body weight loss ( 95% CI 1.2-5.3). CONCLUSIONS Patients with better adherence to RD follow-up meetings were also more physically active. Patients on physical exercise also achieved greater weight reduction following SG, and reported less pain or discomfort. Nutritional counselling and physical exercise are necessary to ensure maximal and sustainable benefits from SG. LEVEL OF EVIDENCE: Level III, Cohort study.

Abstract
BACKGROUND The endocannabinoid (eCB) system plays a key role in the development of obesity and its comorbidities. Limited information exists on the changes in circulating eCBs following bariatric surgery. OBJECTIVES This study aims to (i) assess the circulating levels of eCBs and related molecules and (ii) examine the association between their levels and numerous clinical/metabolic features pre- and post-operatively. METHODS Sixty-five morbidly obese patients (age 42.78 ± 9.27 years; BMI 42.00 ± 5.01 kg/m2) underwent laparoscopic sleeve gastrectomy (LSG) surgery, and were followed up for 12 months. Data collected included anthropometrics and metabolic parameters. The serum levels of the eCBs, 2-arachidonoylglycerol (2-AG), anandamide (AEA); and their related molecules, arachidonic acid (AA) and oleoylethanolamine (OEA) were measured by liquid chromatography-mass spectrometry. RESULTS Levels of 2-AG, AEA, and AA were reduced post operatively with no differences in serum OEA levels. The delta changes in eCB levels between pre- and post-operation were correlated with the delta of different metabolic parameters. Positive correlations were found between delta AA and waist circumference (WC) (r = 0.28, P < 0.05), free fat mass (r = 0.26, P < 0.05), SteatoTest score (r = 0.45, P < 0.05), and ALT (r = 0.32, P < 0.05). Delta AEA levels positively correlated with WC (r = 0.30, P < 0.05). Delta 2-AG levels positively correlated with total cholesterol (r = 0.27, P < 0.05), triglycerides (r = 0.55, P < 0.05), and SteatoTest score (r = 0.27, P < 0.05). Delta OEA levels negatively correlated with fasting glucose levels (r = - 0.27, P < 0.05). CONCLUSIONS This study provides compelling evidence that LSG surgery induces reductions in the circulating 2-AG, AEA, and AA levels, and that these changes are associated with clinical benefits related to the surgery including reduced fat mass, hepatic steatosis, glucose, and improved lipid profile.

Abstract
INTRODUCTION Best practices for patient education in bariatric surgery (BS) remain undefined. The aims of this study were to evaluate the effect of an online lecture on nutrition knowledge, weight loss expectations, and anxiety among BS candidates and present a new tool to assess this knowledge before BS. METHODS An interventional non-randomized controlled trial on 200 BS candidates recruited while attending a pre-BS committee. The first 100 consecutive patients were assigned to the control group and the latter 100 consecutive patients to the intervention group and were instructed to watch an online lecture of 15-min 1-2 weeks prior to surgery. All participants completed a BS nutrition knowledge and the state-trait anxiety inventory (STAI) questionnaires at the pre-BS committee and once again at the pre-surgery clinic. Body mass index (BMI), comorbidities, surgery type, marital status, and number of dietitian sessions were obtained from medical records. RESULTS Data for paired study questionnaires scores were available for 128 patients (n = 69 and n = 59 for the control and intervention groups, respectively), with a mean age and BMI of 40.3 ± 11.4 years and 41.3 ± 4.9 kg/m2, respectively. The BS nutrition knowledge and the state anxiety scores increased for both study groups at the pre-surgery clinic as compared to the pre-BS committee (P ≤ 0.028), but the improvement in the nutrition knowledge score was significantly higher for the intervention group (P = 0.030). No within or between-group differences were found for the trait anxiety items score. The "dream" and "realistic" weight goals were lower than the expected weight loss according to 70% excess weight loss (EWL) for both study groups at both time-points (P < 0.001 for all). CONCLUSION Education by an online lecture prior to the surgery improves BS nutrition knowledge, but not anxiety. ClinicalTrials.gov number: NCT02857647.

Abstract
BACKGROUND AND AIMS Longitudinal assessment of body composition following bariatric surgery allows monitoring of health status. Our aim was to elucidate trends of anthropometric and clinical outcomes 3 years following sleeve gastrectomy (SG). METHODS A prospective cohort study of 60 patients who underwent SG. Anthropometrics including body composition analysis measured by multi-frequency bioelectrical impedance analysis, blood tests, liver fat content measured by abdominal ultrasound and habitual physical activity were evaluated at baseline and at 6 (M6), 12 (M12), and 36 (M36) months post-surgery. RESULTS Sixty patients (55% women, age 44.7 ± 8.7 years) who completed the entire follow-up were included. Fat mass (FM) was reduced significantly 1 year post-surgery (55.8 ± 11.3 to 26.7 ± 8.3 kg; P < 0.001) and then increased between 1 and 3 years post-operatively, but remained below baseline level (26.7 ± 8.3 to 33.1 ± 11.1 kg; P < 0.001). Fat free mass (FFM) decreased significantly during the first 6 months (64.7 ± 14.3 to 56.9 ± 11.8 kg; P < 0.001), slightly decreased between M6 and M12 and then reached a plateau through M36. Weight loss "failure" (< 50% excess weight loss) was noticed in 5.0% and 28.3% of patients at M12 and M36, respectively. Markers of lipid and glucose metabolism changed thereafter in parallel to the changes observed in FM, with the exception of HDL-C, which increased continuingly from M6 throughout the whole period analyzed (45.0 ± 10.2 to 59.5 ± 15.4 mg/dl; P < 0.001) and HbA1c which continued to decrease between M12 and M36 (5.5 ± 0.4 to 5.3 ± 0.4%; P < 0.001). There were marked within-person variations in trends of anthropometric and clinical parameters during the 3-year follow-up. CONCLUSIONS Weight regain primarily attributed to FM with no further decrease in FFM occurs between 1 and 3 years post-SG. FM increase at mid-term may underlie the recurrence of metabolic risk factors and can govern clinical interventions.

Nutritional status following One Anastomosis Gastric Bypass. Clin Nutr 2019; 39:599-605. [PMID: 30922792 DOI: 10.1016/j.clnu.2019.03.008] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2018] [Revised: 03/04/2019] [Accepted: 03/10/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND & AIMS One Anastomosis Gastric Bypass (OAGB) has been accepted as an effective treatment for morbid obesity. However, data are scarce regarding nutritional implications of this procedure. Thus, our aim was to describe the health and nutritional status 12-20 months following OAGB surgery. METHODS A prospective cohort study on patients who underwent OAGB surgery from January 2016 to May 2017 in a large, multi-disciplinary, bariatric clinic. Pre-surgery data including demographic details, anthropometrics, co-morbidities, blood tests and lifestyle habits were obtained from the patients' medical records. Follow-up evaluations were performed 12-20 months post-surgery and data collected included anthropometrics, blood tests, eating and lifestyle parameters, adherence to follow-up regime and gastrointestinal (GI) related side effects. In addition, patients were asked to rate their overall state of health (OSH) from 0 to 100 using a visual analogue scale (VAS). RESULTS Eighty-six OAGB patients (72.1% women) were tested 14.7 ± 2.0 months post-operatively. Their mean age and BMI preoperatively were 46.1 ± 11.4 years and 42.0 ± 4.9 kg/m2, respectively. The mean % excess weight loss at 12-20 months postoperatively was 88.4 ± 19.3%. Lipid and glucose profiles were significantly improved at 12-20 months postoperatively compared to baseline (P < 0.001 for all). Relatively high proportions of nutritional deficiencies were found pre-operatively and postoperatively for iron (33.9% vs. 23.7%, P = 0.238), folate (30.9% vs. 11.8%, P = 0.004), vitamin D (56.6% vs. 17.0%, P < 0.001) and hemoglobin (16.7% vs. 42.9%, P < 0.001). Postoperatively, most participants reported taking multivitamin, calcium, vitamin D and vitamin B12 supplementation (≥62.8%), having participated in at least 6 meetings with a dietitian (51.8%) and presently doing physical activity (69.4%). The mean postoperative OSH VAS score was 88.2 ± 12.3, but most participants reported on flatulence (67.4%) and some reported on diarrhea (25.6%) as GI side effects of the surgery. CONCLUSIONS Substantial improvements in health and anthropometric parameters are found in the short-term follow-up after OAGB, with a satisfactory reported quality of life and adherence to recommendations. However, a high prevalence of some GI side effects, nutritional deficiencies and specially anemia is a matter of concern.

Abstract
Obesity has become one of the most significant health problems worldwide, affecting more than one-third of the global population. The elderly population is not immune to this proportional increase in obesity. To date, there is no cure for obesity, but surgery is the most effective treatment available today.We analyzed the results of bariatric surgery in elderly patients for a period of 3 years. Patients 65 years old and older were included in the study, 451 older adults were included. The mean age of the study group was 67.92 years old (min. 65, max. 84). The mean body mass index (BMI) was 40.32 Kg/m (min. 34 and max. 59). Sleeve gastrectomy (SG) was the most common procedures, and were conducted in 346 (76.72%) patients, gastric bypasses (GBPs) in 53 (11.75%) of which 33 were roux en y GBP (7.32%) and 20 mini GBPs (4.43%), gastric banding in 48 (10.64%), and duodenal switching in 4 (0.89%) cases.There were 40 (8.86%) patients with perioperative complications, 6 (1.33%) required re-operations, 12 (2.66) patients with operative complications were treated conservatively, 8 (1.77%) re-admission 5 of them with intrabdominal abscess, and 14 (3.10%) with co-morbidities complications. More than 76% of the patients had co-morbidities, 1 year after surgery the average remission of diseases was 34.74%, the improvement was49.67% and no changes in the co-morbidities was 15.59%. There were no deaths reported in this cohort.The mean excess body weight (EBW) loss among the patients was 70.76% (from 32% to 92%). No failure of weight loss (less than 25% of EBW loss) was observed after the first postoperative year.Bariatric surgery offers obese elderly patients an acceptable result, and it can be offered to improve the quality of life of these patients. A new consensus conference panel is needed to set appropriate recommendations regarding criteria that limit bariatric surgery in older adults.

Abstract
OBJECTIVE We examined short and long-term outcomes of bariatric surgery in patients with obesity and type 1 diabetes mellitus (T1DM). METHODS We reviewed the records of all adults insured by Maccabi Healthcare Services during 2010 -2015, with body mass index (BMI) ⩾30 kg/m2 and T1DM; and compared weight reduction and glucose control according to the performance of bariatric surgery. BMI and glycated hemoglobin (HbA1c) levels were extracted for baseline and every 6 months, for a mean 3.5 years. RESULTS Of 52 patients, 26(50%) underwent bariatric surgery. Those who underwent surgery were more often female and with a longer duration of diabetes. Immediately postoperative, 4(15%) developed diabetic ketoacidosis, while 6(23%) experienced severe hypoglycemic episodes. The mean BMI decreased among surgery patients: from 39.5±4.4 to 30.1±5.0 kg/m2 (p < 0.0001); and increased among those who did not undergo surgery: from 33.6±3.9 to 35.1±4.4 kg/m2 (p = 0.49). The mean HbA1c level decreased during the first 6 months postoperative: from 8.5±0.9% to 7.9±0.9%; however, at the end of follow-up, was similar to baseline, 8.6±2.0% (p = 0.87). For patients who did not undergo surgery, the mean HbA1c increased from 7.9±1.9% to 8.6±1.5% (p = 0.09). CONCLUSIONS Among individuals with obesity and T1DM, weight loss was successful after bariatric surgery, but glucose control did not improve. The postoperative risks of diabetic ketoacidosis and severe hypoglycemic episodes should be considering when performing bariatric surgery in this population.

Conversion for failed adjustable gastric banding warrants hiatal scrutiny for hiatal hernia. Surg Endosc 2018; 33:2231-2234. [PMID: 30341651 DOI: 10.1007/s00464-018-6509-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Accepted: 10/11/2018] [Indexed: 12/31/2022]
Abstract
BACKGROUND Failure or complications following laparoscopic adjustable gastric banding (LAGB) may necessitate band removal and conversional surgery. Band position and band-induced chronic vomiting create ideal conditions for de novo hiatal hernia (HH) formation. HH presence impedes and complicates conversional surgery by obscuring crucial anatomical landmarks and hindering precise gastric sleeve or pouch formation. The aim of this study was to evaluate the incidence of a HH in patients with an LAGB undergoing conversion compared to patients undergoing primary bariatric surgery (BS). METHODS Retrospective review of consecutive BS performed between 2010 and 2015. Data collected included demographics, anthropometrics, comorbidities, previous BS, preoperative and intra-operative HH detection, operation time, perioperative complications and length of hospital stay. RESULTS During the study period, 2843 patients (36% males) underwent BS. Of these, 2615 patients (92%) were "primary" (no previous BS-control group), 197 (7%) had a previous LAGB (study group), and 31 (1%) had a different previous BS and were excluded. Reasons for conversion included weight regain, band intolerance and band-related complications. Mean age and body mass index were similar between the study and the control groups. HH was preoperatively diagnosed by upper gastrointestinal (UGI) fluoroscopy in 9.1% and 9.0% of the LAGB and control groups (p = NS), respectively. However, HH was detected intra-operatively in 20.3% and 7.3%, respectively (p < 0.0001). CONCLUSIONS Preoperative diagnosis of a HH by UGI fluoroscopy for patients who have undergone LAGB is unreliable. Intra-operative hiatal exploration is highly recommended in all cases of conversional BS after LAGB.

Abstract
BACKGROUND People are living longer than they were expected to 2 decades ago. Increased life expectancy and reduced mortality encompasses a simultaneous increase in the number of older adults with obesity that entails an increase of co-morbidities, such as diabetes, hypertension, cancer, and many other diseases. The aim of our study was to compare the outcomes of bariatric surgery in patients age ≥65 in comparison with younger patients. METHODS This retrospective study compares bariatric surgeries performed in a private institution between the years 2013 and 2015. The study included 9044 patients divided into an older group (451 patients) and the younger group (8593 patients). RESULTS In the younger group, bariatric surgery is distributed as follows: 77.68% sleeve gastrectomy, 12.72% gastric banding, 9.27% gastric bypass, and .33% duodenal switch or biliopancreatic diversion; in the older group: 70.51% sleeve gastrectomy, 15.08% gastric bypass, 13.97% gastric band, and .44% biliopancreatic diversion. In the control group 550 cases (6.4%) underwent revisional surgery; 64 cases (14.10%) underwent revision in the older group. Older patients lost less excess weight than younger patients (72.44% versus 86.11%, respectively). Older patients presented higher rates of complications (8.42% versus 5.59%), co-morbidities (77.60% versus 55.45%), and revisions (1.33% versus .77%). There was no statistical difference in hospital stay between older group and control group (2.27 versus 2.23, respectively). When performing a Clavien-Dindo classification, we demonstrated significant differences in class 3B and 4A and no differences in other classes. Two deaths occurred in the control group. Diabetes, fatty liver, and sleep apnea have been improved or remitted in >90% of patients in both groups, hypertension and hyperlipidemia by >80%, and hyperuricemia and ischemic heart disease were improved or resolved in >70% of the patients CONCLUSIONS: Bariatric surgery in the elderly has more complications, but it can still be considered safe.

Abstract
INTRODUCTION Various definitions for bariatric surgery (BS) success exist, with weight loss and comorbidity resolution outcomes being the most prominent. The study's aim was to compare how various healthcare professionals perceive success in BS. METHODS A 29-item, 10-point Likert scale online survey was distributed via email to Israeli healthcare professionals involved in the different BS aspects using common national professional organizations. These included bariatric surgeons, dietitians, social workers, psychologists, psychiatrists, primary care physicians, gastroenterologists, and nurses. Statement relevancy to BS success was rated. An item was classed as "very important" for BS success if at least 70% of participants rated it 8 or higher in each subgroup. Inter-observer agreement was calculated using kappa statistics. Data on specific occupation, years-in-practice, and major workplace were collected as well. RESULTS A total of 155 responses was obtained. The majority of respondents were dietitians (34.8%, n = 54), followed by bariatric surgeons (31.0%, n = 48) and nurses (14.8%, n = 23). Most respondents work mainly at public hospitals (32.9%, n = 51), followed by private hospitals (26.5%, n = 41). The mean years-in-practice among all healthcare professionals was 8.5 ± 8.5 years. Overall inter-observer agreement for prioritized items in accordance to BS success among all health professional subgroups was fair (Fleiss kappa = 0.278, P < 0.001), while dietitians and mental health specialists showed the highest agreement rate (Cohen's kappa = 0.592, P < 0.001). CONCLUSION The study highlights the various views on defining BS success by different healthcare professionals, although there was some overlap of core outcomes prioritized by all professionals. International uniform definitions for BS success are required.

Abstract
BACKGROUND Data on adherence to postoperative lifestyle recommendations by bariatric patients are scarce. Thus, the aim of this study was to evaluate adherence to selected recommendations during the first year following laparoscopic sleeve gastrectomy (LSG) surgery. METHODS A prospective cohort study with 12 months of follow-up on 100 LSG patients was conducted. Data were collected at baseline and at 3 (M3), 6 (M6), and 12 (M12) months post-surgery and included anthropometrics, biochemical tests, food intake, food tolerance, common surgery-related side effects, physical activity (PA), supplementation, and number of follow-up meetings with a dietitian. RESULTS Data were available for 77 patients (57.1% women, mean age 43.1 ± 9.3 years and preoperative BMI 42.1 ± 4.8 kg/m2). Only a minority of the patients adhered to the recommended protein intake ≥60 g/day at all time points (≤40.3%) and ≥6 meetings with a dietitian at M12 (41.6%). Half of the patients performed ≥150 min/week of PA at all time points (≤50.6%) as recommended. PA of ≥150 min/week was associated with better lipid and glucose changes at M6 and M12 (P ≤ 0.044). Most of the patients adhered to the recommended supplementation at all time points (≥57.1%). Adherence to supplementation at M12 was significantly associated with higher serum levels of folic acid, iron, hemoglobin, and vitamins D and B12 (P ≤ 0.056 for all). Adherence to all recommendations was not significantly associated with excess weight loss ≥60% at M12 (P ≥ 0.195 for all). CONCLUSION Bariatric patients have medium to high adherence to the major lifestyle recommendations during the first year following LSG; however, adherence to those recommendations was not related to better weight loss at short-term follow-up. Adherence to recommended supplementation was associated with better micronutrient status 1 year postoperatively.

Abstract
BACKGROUND Single anastomosis gastric bypass (SAGB) has been established as a safe and effective bariatric procedure. SAGB has also been suggested as a conversion option from other procedures, but so far not extensively explored in that direction. METHODS The study retrospectively reviewed and analyzed 154 consecutive SAGB procedures, including 48 conversional SAGB (cSAGB) and 106 primary SAGB (pSAGB). Preoperative physical dimensions and perioperative complications were obtained. Patients were followed 1, 3, and 6 months postoperatively, with weight measurements compared between groups. RESULTS Operative times were longer in the cSAGB group but length of hospital stay was the same for both groups. Sixty-five percent of the cSAGB group had adjustable banding as a primary operation, and 94 % opted for conversion due to insufficient weight loss or regain thereof. Follow-up data availability was 98, 82, and 79 % for the three checkpoints. Three and 6 months postoperatively, cSAGB had inferior mean excess weight loss (EWL) compared to pSAGB, though both groups were successful after 6 months (mean EWL >50 %). Body mass index loss was significantly higher for pSAGB for the first postoperative 3 months. Low complication rates in both groups precluded statistical comparison in that respect. DISCUSSION Initial weight loss after conversional SAGB is inferior to primary SAGB after 6 months. The observed safety of cSAGB is comparable to previous evidence for this procedure in the conversional settings. CONCLUSION SAGB may be considered as a safe and effective conversional procedure, but not as effective as pSAGB for initial weight loss.

Abstract
BACKGROUND Low postoperative protein intake may represent a modifiable risk factor that leads to fat free mass (FFM) loss postlaparoscopic sleeve gastrectomy (LSG), but data concerning this phenomenon is scarce. OBJECTIVES To evaluate the association between daily protein intake and relative FFM loss at 6 (M6) and 12 (M12) months after LSG surgery. SETTINGS Private hospital and university hospital. METHODS A prospective cohort study with 12 months follow-up of 77 patients who underwent LSG surgery. Anthropometrics including body composition analysis measured by multifrequency bioelectrical impedance analysis, 3-day food diaries, food intolerance, and habitual physical activity were evaluated at baseline and at M3, M6, and M12. RESULTS Repeated body composition measurements and food diary were available for 77 patients (45 women) at M6 and for 68 patients at M12. Mean age was 42.7±9.4 years and mean preoperative body mass index was 42.2±4.8 kg/m2. A protein intake of≥60 g/d was achieved in 13.3%, 32.5% and 39.7% of the study participants at M3, M6 and M12, respectively. FFM significantly decreased at M6 and stabilized at M12. Protein intake of≥60 g/d was associated with a significantly lower relative FFM loss at M6 among women (8.9±6.5% versus 12.4±4.1%; P = .039) and this trend was also reported among men (9.5±5.5% versus 13.4±6.0%; P = .068). A logistic regression for the prediction of FFM loss of≥10% at M6, indicated that protein intake≥60 g/d is a strong protective factor (odds ratio = 0.29, 95% confidence interval .09-.96, P = .043). CONCLUSION Our study supports the currently recommended protein intake goal of≥60 g/d as an efficient strategy for better preservation of FFM post-LSG.

Abstract
BACKGROUND Gallbladder (GB) cancer is rare. Most cases are incidentally found in specimens after a cholecystectomy. Cholelithiasis is almost always present when this diagnosis is made. Obesity is a known risk factor for gallstone formation and thus may be related to GB cancer. OBJECTIVES To highlight the importance of evaluating the gallbladder before surgery, resecting the gallbladder whenever required, and screening the resected tissue for malignancy. METHODS We retrospectively searched a prospectively maintained database of all bariatric procedures during the last 8 years for cases of concomitant laparoscopic sleeve gastrectomy (LSG) and laparoscopic cholecystectomy (LC). Pathologic reports of the gallbladders were reviewed. Demographic data and perioperative parameters were documented. RESULTS Of 2708 patients reviewed, 1721 (63.55%) were females and 987 (36.45%) males. Excluded were 145 (5.35%) who had a previous cholecystectomy. Of the remaining 2563, 180 (7.02%) had symptomatic gallbladder disease and underwent LSG with LC. Of these, two females (BMI 53 kg/m2 and 47 kg/m2, both age 60) were found by histological examination to have adenocarcinoma in their GB specimens (1.11%). Both were reoperated, which included partial hepatectomy of the GB bed, resection of the cystic stump, lymph node dissection, and resection of the port sites. One patient is doing well, with no evidence of disease at a postoperative follow-up of 4 years. The second patient had recurrent disease with peritoneal spread and ascites 20 months post-surgery and died 18 months later. CONCLUSIONS GB cancer is a rare finding in cholecystectomy specimens. The incidence of this entity might be higher in obese older females owing to the higher incidence of cholelithiasis in these patients.

Assessment of perioperative complications following primary bariatric surgery according to the Clavien-Dindo classification: comparison of sleeve gastrectomy and Roux-Y gastric bypass. Surg Endosc 2015; 30:273-8. [PMID: 25861906 DOI: 10.1007/s00464-015-4205-y] [Citation(s) in RCA: 46] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2014] [Accepted: 03/31/2015] [Indexed: 12/19/2022]
Abstract
BACKGROUND Laparoscopic Roux-Y gastric bypass (LRYGBP) is the gold-standard procedure for the treatment of morbid obesity. It has been reported to be somewhat more efficient and durable than laparoscopic sleeve gastrectomy (LSG). However, it is considered more invasive and, therefore, more hazardous. There is a lack of unity in complication reporting following bariatric surgery. Thus, there is a possible misconception regarding the relative safety of the two major bariatric procedures performed worldwide. This may have contributed to a shift in practice with LSG gaining momentum "at the expense" of LRYGBP. The aim of this study was to evaluate the relative safety of primary LSG and LRYGBP according to the Clavien-Dindo complication grading system. METHODS A total of 2651 and 554 patients underwent primary LSG and LRYGBP, respectively at three high-volume centers. Thirty-day perioperative complications were recorded and graded. Length of hospital stays (LOS) and readmission rates were collected as well. RESULTS Complications occurred in 110 (3.7%) and 24 (4.3%) patients following LSG and LRYGBP, respectively (p = 0.9). No significant difference was found between the groups regarding overall and complication-grade-specific rates. Individual complication types were unevenly distributed, but not significantly so. Patients with complications were older than those without (47 and 43 years, respectively; p = 0.01). Gender was not a risk factor for complication. Median LOS and readmission rates were not significantly different. CONCLUSIONS LSG and LRYGBP are equally safe, at least in the perioperative period. Acknowledging and conveying this finding to surgeons and patients alike is important and might cause a pendulum shift in the distribution of bariatric procedures performed.

Abstract
The obesity epidemic has been recognized as a worldwide problem. More than 1/3 of the adults and about 15% of children and adolescents are overweight. In the search for the reasons for obesity and refractory obesity, some research efforts have recently been directed into the relationship between obesity and attention deficit hyperactivity disorder (ADHD). This link can be explained by two theoretical approaches: ADHD leads to obesity because of the impulsive behavior of ADHD patients; both obesity and ADHD originate from a similar psycho-pathological mechanism. ADHD is usually diagnosed in childhood with symptoms of hyperactivity, impulsivity, and distraction, often continuing into adulthood with symptoms of disorganization, frustration, and excessive emotional reaction. Treatment of ADHD requires a multidisciplinary approach of medication, psychological treatment, occupational therapy (in children) and nutritional assistance. Most studies of the association between ADHD and obesity were performed on subjects seeking help for obesity problems. In this population (both children and adults), the percentage of ADHD was found to be significantly higher than the prevalence of ADHD in the general population. Overweight subjects with ADHD, who were treated with medications, showed improved patterns of weight loss and maintenance. In addition, patients diagnosed with ADHD had lower compliance with follow-up visits after bariatric surgery. It seems that the problem is in the correct diagnosis of ADHD in obese patients, followed by medical as well as cognitive behavioral treatment, that can turn the impulsivity into an advantage, driving patients to positive pathways such as physical activity.

Abstract
BACKGROUND Modifications to conventional laparoscopic cholecystectomy (CLC) are aimed at decreasing abdominal wall trauma and improving cosmetic outcome. Although single-incision laparoscopic surgery (SILS) provides excellent cosmetic results, the procedure is technically challenging and expensive compared to the conventional laparoscopic approach. OBJECTIVES To describe a novel, hybrid technique combining SILS and conventional laparoscopy using minimal abdominal wall incisions. METHODS Fifty patients diagnosed with symptomatic cholelithiasis were operated using two reusable 5 mm trocars inserted through a single 15 mm umbilical incision and a single 2-3 mm epigastric port. This technique was clubbed "minimal incision laparoscopic cholecystectomy" (MILC). RESULTS MILC was completed in 49 patients (98%). In five patients an additional 3 mm trocar was used and in 2 patients the epigastric trocar was switched to a 5 mmtrocar. The procedure was converted to CLC in one patient. Mean operative time was 29 minutes (range 18-60) and the average postoperative hospital stay was 22 hours (range 6-50). There were no postoperative complications and the cosmetic results were rated excellent by the patients. CONCLUSIONS MILC is an intuitive, easy-to-learn and reproducible technique and requires small changes from CLC. As such, MILC may be an attractive alternative, avoiding the cost and complexity drawbacks associated with SILS.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is gaining credibility as a simple and efficient bariatric procedure with low surgical risk. Since surgical treatment for morbid obesity is relatively rare in adolescents, few results have bten accumulated so far. OBJECTIVES To prove the safety and efficacy of LSG turgery in an adolescent population METHODS Data were prospectively collected regarding adolescent patients undergoing LSG. All patients underwent pre- and postoperative medical and professional evaluation by a multidisciplinary team. RESULTS Between the years 2006 and 2011, 32 adolescents underwent LSG in our center (20 females and 12males). Mean age was 16.75 years (range 14-18 years), mean weight was 121.88 kg (83-178 kg), and mean body mass index 43.23 (35-54). Thirty-four comorbid conditions were identified. LSG was the primary bariatric procedure in all the patients. Mean operative time was 60 minutes (range 45-80 min). Tiere were two complications (6.25%): an early staple line leak and a late acute cholecystitis. There were no deaths. Mean percent excess weight loss at 1, 3, 6, 9,12, 24, 36, 48, and 60 months post-surgery was 27.9%, 41.1%, 62.6%, 79.2%, 81.7%, 71%, 75%, 102.9% and 101.6%, respectively. Comorbidities were completely resolved or ameliorated within 1 year folllowing surgery in 82.4% and 17.6%, respectively. CONCLUSIONS LSG is feasible and safe in morbidly obese adolescents, achieving efficient weight loss and impressive resolution of comorbidities. Further studies are required to evaluate the long-term results of this procedure as well as its place among other bariatric options.

Abstract
OBJECTIVE To describe the incidence of, the patterns of clinical presentation of, and the reasons for portomesenteric vein thrombosis among patients who underwent laparoscopic bariatric surgery. DESIGN Retrospective, multicenter study. SETTING Six academic bariatric centers. PATIENTS Morbidly obese patients diagnosed with portomesenteric vein thrombosis following laparoscopic bariatric surgery between January 2007 and June 2012. MAIN OUTCOME MEASURES Clinical presentation, diagnostic measures used, treatments employed, outcome, and hematologic workup of patients. RESULTS Of 5706 patients who underwent laparoscopic bariatric surgery, 17 (0.3%) had portomesenteric vein thrombosis, 16 after sleeve gastrectomy and 1 following adjustable gastric banding. Seven patients were women, the mean age was 38 years, and the mean body mass index was 44.3. The median time to presentation was 10.1 days, and the median time to diagnosis was 11.7 days. New-onset epigastric pain was present in all patients, whereas other signs and symptoms were sporadically found. Computed tomography was performed and was diagnostic in 16 cases. Ultrasonography was used for 9 patients, and positive results were found for 8 of these patients. Patients were treated by anticoagulation with subcutaneous low-molecular-weight heparin (n = 15) or intravenous heparin (n = 2), followed by warfarin sodium. One patient underwent transhepatic portal infusion of streptokinase. Three patients required surgery: laparoscopic splenectomy due to infarct and abscess for 1 patient and laparotomy for 2 patients (with necrotic small-bowl resection for 1 of these patients). There were no deaths. CONCLUSIONS Portomesenteric vein thrombosis is rare after laparoscopic bariatric surgery. Familiarity with this dangerous entity is important. Prompt diagnosis and care, initiated by a high index of suspicion, is crucial.

Abstract
PURPOSE To study whether intravaginal application of seminal plasma after follicle aspiration has the potential to increase implantation and clinical pregnancy rates after IVF-ET. METHODS We conducted a prospective, double-blind, placebo-controlled randomized study of 230 patients undergoing IVF-ET cycles. 500 μL of Fresh seminal plasma from the patient's partner or culture medium (placebo) were injected in the vaginal vault just after follicle aspiration. The main outcome measured was ongoing clinical-pregnancy rate. RESULTS After ET cancellation in ten patients due to lack of fertilization or embryo cleavage, 220 embryo transfers (103 and 117 in the study and control groups) resulted in a clinical pregnancy rate of 36.9 % and 29.1 % for the study and control groups, corresponding to a relative increase of 26.8 %. After an early pregnancy loss of 13.1 % (5/38) and 23.5 % (8/34) in the study and control groups respectively an ongoing pregnancy rate of 32.0 % (33/103) and 22.2 % (26/117) was achieved corresponding to a relative increase of 44.1 %. Multivariate logistic regression analysis adjusted for study group, age, infertility, and cycle characteristics did not demonstrate any parameter that could predict occurrence of clinical pregnancy rates after IVF-ET. CONCLUSIONS Patients who underwent SP intravaginal insemination after oocyte pick-up reached higher implantation and clinical pregnancy rates following ET compared to controls, although the difference did not reach statistical significance. More studies and variable methodologies may clarify the potential clinical effect of SP in improving live birth rates after ART.
