Review
Chyloperitoneum and chylothorax (ChP/ChT) are rare complications after bariatric surgery. This systematic review aims to evaluate the incidence, cause, treatment, and outcome of ChP and ChT after bariatric surgery. This review investigates published English language scientific literature systematically in an attempt to answer these questions. Our literature search revealed 66 studies, of which 23 were included. There were a total of 40 patients (38, ChP; 2, ChT). Eighteen of 40 (43.9%) patients were treated laparoscopically, and one patient (2.44%) underwent thoracoscopy and ligation of the thoracic duct. Both ChP and ChT are rare complications after bariatric surgery.

Review
Predisposing factors of new-onset orthostatic intolerance (OI) after bariatric surgery (BS) are unknown. The purpose of this study is to summarize current existing data on new-onset OI after BS. Materials and methods were considered for a search of articles that were published by the 30 of July 2020. A systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and in line with the protocol agreed by all authors was conducted. Of the 604 initially identified articles, four studies were found to match the established criteria and were extracted for eligibility. 83.3% were female. Hypertension, type 2 diabetes mellitus, and obstructive sleep apnea syndrome were the most frequently reported comorbidities. Surgical intervention such as revision, conversion, or reversal was not documented in these studies. Awareness of this issue must be raised due to the possibility of reduced quality of life and the risk of syncope.

Meta-Analysis Review
INTRODUCTION
Effective workup and listing of end-stage renal disease (ESRD) patients for renal transplantation, often with multiple co-morbidities, poses a challenge for transplant teams. Obesity is a common co-morbidity associated with adverse outcomes in ESRD and kidney transplant (KT) recipients. Bariatric and metabolic surgery (BMS) has long been established as a safe and effective treatment for morbid obesity. In this study, the authors aimed to evaluate the strength of evidence for both the efficacy and safety of bariatric surgery in patients with ESRD or kidney transplantation.
METHODS
A literature search was performed using key terms including "transplantation", "kidney", "renal", "obesity", and "bariatric". Databases searched include MEDLINE, EMBASE and Web of Science from inception to date (April 2021). Methodological quality was assessed using the Newcastle-Ottawa tool. Selected articles were then categorised into patients awaiting waiting list acceptance, patients awaiting transplantation, patients undergoing simultaneous BMS + KT and patients undergoing BMS following a previous renal transplant. Summary effects are presented with a level of statistical significance and 95% Confidence Intervals.
RESULTS
A total of 28 articles were selected following the literature search. Fourteen studies on patients awaiting listing (n = 1903), nine on patients on the KT waiting list (n = 196), a single study on simultaneous BMS and KT and ten studies on patients undergoing BMS following KT (n = 198). Mean change in BMI for patients awaiting listing was -11.3 kg/m (95%CI: -15.3 to -7.3, p < 0.001), mean change in BMI for patients listed for KT was -11.2 kg/m 2(95%CI: -12.9 to -9.5, p 0.001) and mean change for patients with prior KT was -11.0 kg/m (95%CI: -7.09 to -14.9, p < 0.001). The combined mortality rate for patients who had undergone both BMS and KT was 4% (n = 15).
DISCUSSION
This review demonstrates BMS is both safe and efficacious in patients with ESRD prior to KT and in those post KT. It would enable difficult-to-list obese recipients the possibility to undergo transplantation and should be considered as part of the work up process.

Review
BACKGROUND
Although there is evidence to support the relationship between abuse history and obesity, the association between abuse history and outcomes after bariatric surgery is not well-established. We aimed to summarize the current literature examining this relationship, as well as provide clinical recommendations to optimize postoperative outcomes.
METHODS
PubMed and SCOPUS databases were queried to identify relevant published studies.
RESULTS
Overall, 20 studies were included. Rates of the various types of abuse reported in the bariatric surgery population varied widely across studies, as did the methodology used to assess it. The majority of studies found no significant associations between abuse history and postoperative weight loss outcomes. The literature examining the relationship between abuse history and postoperative psychiatric outcomes was less conclusive.
CONCLUSIONS
Most current evidence demonstrates that abuse history is not associated with weight loss outcomes after bariatric surgery. Literature on postoperative psychiatric outcomes is mixed, and more robust studies are needed to further investigate the relationship between abuse history and postoperative psychiatric outcomes. Importantly, abuse history should not preclude patients from undergoing bariatric surgery. Of note, patients may benefit from careful monitoring for emotional distress and worsening of psychiatric comorbidities after surgery and psychiatric counseling and treatment when indicated.

Review
Laparoscopic surgery in patients with obesity with situs inversus (SI) may pose interesting challenges to diagnosing and managing due to the mirror image anatomy. Since in SI patient's organs are displaced, the surgery requires high levels of precision and hand-eye coordination. SI and bariatric surgery may pose challenges for the surgical team. A total of 46 patients were reported in this systematic review. The mean age of cases was ~39 years (range 19-59), and the mean BMI was 45.9 kg/m (range 35-76). Of the included 46 patients, 39 had SIT. In the majority of the included patients, either a laparoscopic Roux-en-Y gastric bypass (LRYGB) (in 15 patients (35%)) or a laparoscopic sleeve gastrectomy (LSG) (in 21 patients (45.6%)) was performed. Complications were documented in 3 cases.

Meta-Analysis
INTRODUCTION
Managing nutritional deficiencies is an essential component in the treatment of severe obesity. Vitamin D deficiency is often reported in investigations in severely obese cohorts. However, no prior study has summarized findings on this topic. Consequently, the aim of this systematic review and meta-analysis was to investigate the 25-hydroxyvitamin D [25(OH)D] status in individuals with severe obesity in different regions worldwide. We also evaluated levels of calcium, parathyroid hormone (PTH), and magnesium as secondary outcome measures.
METHODS
We searched Medline, PubMed, Scopus, the Cochrane Library, and EMBASE for relevant observational studies published in English from 2009 to October 2021. The heterogeneity index among the studies was determined using the Cochran (Q) and I2 tests. Based on the heterogeneity results, the random-effect model was applied to estimate the prevalence of vitamin D deficiency.
RESULTS
We identified 109 eligible observational studies. Overall, 59.44% of patients had vitamin D deficiency [25(OH)D <20 ng/mL], whereas 26.95% had vitamin D insufficiency [25(OH)D 20-30 ng/mL]. Moreover, the mean 25(OH)D level was 18.65 ng/mL in 96 studies. The pooled mean estimate of the serum calcium, PTH, and magnesium was 9.26 mg/dL (95% confidence interval [CI]: 9.19-9.32, I2 = 99.7%, p < 0.001), 59.24 pg/mL (95% CI: 54.98, 63.51, I2 = 99.7%, p < 0.001), and 0.91 mg/dL (95% CI: 0.84, 0.98, I2 = 100.0%, p < 0.001), respectively. The results of the subgroup analysis indicated that the mean estimates of 25(OH)D were highest in North America (21.71 ng/mL [19.69, 23.74], [I2 = 97.2%, p < 0.001]) and lowest in Southeast Asia (14.93 ng/mL [14.54, 15.33], [I2 = 0.0%, p = 0.778]).
CONCLUSION
The results obtained showed a significant prevalence of vitamin D deficiency among severely obese individuals in various geographical regions, whereas the highest and lowest mean estimates were reported for North America and Southeast Asia, respectively.

Meta-Analysis Review
Intussusception is a rare yet potentially life-threatening complication following Roux-en-Y gastric bypass (RYGB). Multiple case reports have described this complication, and recently, several retrospective studies have been published describing the surgical treatment of intussusception. The aim of this study was to determine the incidence of intussusception following RYGB and provide insight into outcomes of subsequent operative treatment. A systematic search was performed using the PubMed and Cochrane databases. Article selection was performed using the preferred reporting items for systematic reviews and meta-analyses criteria, and selecting articles describing the incidence of intussusception following RYGB. Data was pooled only when 3 or more comparable studies reported on the same outcome. The incidence of intussusception and outcomes of subsequent treatment were analyzed. Furthermore, all published case reports describing intussusception following RYGB were analyzed. A total of 74 studies published between 1991 and 2020 were included, describing 191 patients who underwent RYGB and developed intussusception. We retrieved 68 case reports, including 84 patients, and 6 retrospective studies describing outcomes of surgical treatment in 107 patients, which were used to pool data. There was a predominance of females among the included patients (85%-98%), and patients had significant weight loss following RYGB. The pooled incidence of intussusception following RYGB was .64%. Resection of the affected segment was performed in 34% of the patients. A pooled recurrence rate of 22% was found during follow-up. Resection and reconstruction of the jejunojejunostomy appears to be associated with the lowest risk of recurrence and acceptable complication rates. The pooled incidence of intussusception following RYGB is 0.64%. Typically, patients are female with significant weight loss after RYGB. Symptoms include abdominal pain, nausea, and vomiting. Diagnosis is based on clinical findings and computed tomography scans, warranting early surgical exploration due to the high risk for ischemia. Resection of the jejunojejunostomy appears to be associated with the lowest recurrence rates and acceptable complication rates.
