Clinical outcomes of outpatient thyroidectomy: A systematic review and single-arm meta-analysis.

BACKGROUND: The aim of this meta-analysis is to investigate the safety of outpatient thyroidectomy based on 24-h and same-day discharge criteria. METHODS: CENTRAL, Embase, PubMed, and Scopus were searched. A meta-analysis of selected studies was performed. The review was registered prospectively with PROSPERO (CRD42022361134). RESULTS: Thirty-one studies met the eligibility criteria, with a total of 74328 patients undergoing thyroidectomy in an outpatient setting based on 24-h discharge criteria. Overall postoperative complications after outpatient thyroidectomies were 5.7% (95%CI: 0.049-0.065; I2 â€‹= â€‹97.3%), consisting of hematoma (0.4%; 95%CI: 0.003-0.005; I2 â€‹= â€‹83.4%), recurrent laryngeal nerve injury (0.4%; 95%CI: 0.003-0.006; I2 â€‹= â€‹93.5%), and hypocalcemia (1.6%; 95%CI: 0.012-0.019; I2 â€‹= â€‹93.7%). The rate of readmission was 1.1% (95%CI: 0.007-0.015; I2 â€‹= â€‹95.4%). Results were similar for same-day criteria. CONCLUSIONS: Our analysis demonstrated that outpatient thyroidectomy is a safe procedure in the management of thyroid disease for selected patients.

One Anastomosis Gastric Bypass as Revisional Surgery Following Sleeve Gastrectomy: A Systematic Review and Meta-Analysis.

BACKGROUND: Although sleeve gastrectomy (SG) is the most performed metabolic and bariatric surgery (MBS) worldwide, some patients require conversional procedures due to weight recurrence or late complications. Recently, one-anastomosis gastric bypass (OAGB) gained popularity as a viable option to address those problems. The aim of this meta-analysis is to assess the safety and efficacy of conversional OAGB after primary SG in the management of patients with obesity. METHODS: Cochrane, Embase, PubMed, Scopus, and Web of Science were searched for articles from their inception to February 2023 by two independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) system. The review was registered prospectively with PROSPERO (CRD42023403528). RESULTS: From 1,117 studies screened, twenty studies met the eligibility criteria, with a total of 1,057 patients with obesity undergoing conversional OAGB after primary SG. The mean age ranged from 28.2 to 49.5 years, and 744 patients (75.2%) were women. At one year after revisional OAGB, the pooled mean percent excess weight loss (%EWL) was 65.2% (95%CI: 56.9, 73.4, I2 = 97%). The pooled mean %EWL after conversional OAGB was 71.1% (95%CI: 62.2, 80.0, I2 = 90%) at two years and 71.6% (95%CI: 61.0, 82.2, I2 = 50%) at five years. Additionally, resolution rates of diabetes and hypertension were 65.4% (95%CI: 0.522, 0.785, I2 = 65%) and 58.9% (95%CI: 0.415, 0.762, I2 = 89%), respectively. CONCLUSIONS: Our meta-analysis demonstrated OAGB as an effective conversional procedure after primary SG in terms of weight loss and obesity-associated medical problems for selected patients. Despite the promising results, further randomized controlled studies with larger sample sizes and more extended follow-up periods are necessary to determine if the OAGB is the best conversional surgery after SG.

NSAIDs and Corticosteroids for the Postoperative Management of Age-Related Cataract Surgery: A Systematic Review and Meta-analysis.

PURPOSE: To evaluate the safety and efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids in the postoperative management of cataract surgery for age-related cataract in adults. DESIGN: Meta-analysis. METHODS: Cochrane, Embase, PubMed, Scopus, Web of Science and CINAHL were searched for articles using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) system. The review was registered prospectively with PROSPERO (CRD42022364733). Randomized controlled trials of patients undergoing age-related cataract surgery treated with corticosteroids, NSAIDs, or a combination were included. RESULTS: A total of 19 studies were included, with 3473 patients (3638 eyes) treated following cataract surgery with NSAIDs (n = 1479), corticosteroids (n = 1307), or a combination (n = 687). Combination treatment demonstrated favorable best-corrected visual acuity compared to corticosteroids 4 to 6 weeks postoperatively (MD = -0.01 logMAR, 95% CI: -0.02, -0.01, I2 = 0%). NSAIDs had more favorable flare values than corticosteroids on day 7 (MD = -9.17 photons/ms, 95% CI = -16.52, -1.82, I2 = 94%), day 14 (MD = -5.23 photons/ms, 95% CI = -8.35, -2.11, I2 = 94%), and 4 to 6 weeks (MD = -1.62 photons/ms, 95% CI = -3.03, -0.20, I2 = 93%) postoperatively. Furthermore, 4 to 8 weeks postoperatively, patients treated with NSAIDs showed lower central macular thickness (MD = -13.26 µm, 95% CI = -18.66, -7.86, I2 = 81%) compared to those treated with corticosteroids. NSAIDs and combination treatment were associated with a lower incidence of central macular edema (OR = 0.16, 95% CI = 0.07, 0.35, I2 = 61%; OR = 0.21, 95% CI = 0.10, 0.45, I2 = 31%) than corticosteroids 4 to 8 weeks postoperatively. CONCLUSIONS: NSAIDs and combination treatments could be regarded as more effective and safer alternatives to corticosteroids alone in the postoperative management of cataract surgery. Further studies should be conducted to determine why this evidence has not been reflected in practice patterns, and to further compare the effectiveness of NSAIDs and combination treatments.

Evaluation of Long-Term Nutrition Outcomes After Duodenal Switch: A Systematic Review and Meta-Analysis.

BACKGROUND: Biliopancreatic diversion with duodenal switch (BPD-DS) is the most effective and durable metabolic and bariatric surgery to achieve a target weight loss. However, many surgeons are hesitant to adopt BPD-DS due to a lack of training, technical complexity, and long-term nutrition deficiencies. This meta-analysis aimed to investigate long-term nutrition outcomes after primary BPD-DS in the management of obesity. METHODS: Cochrane, Embase, PubMed, Scopus, and Web of Science were searched for articles from their inception to February 2023 by 2 independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) system. The review was registered prospectively with PROSPERO (CRD42023391316). RESULTS: From 834 studies screened, 8 studies met the eligibility criteria, with a total of 3443 patients with obesity undergoing primary BPD-DS. At long-term follow-up (≥5 years), 25.4% of patients had vitamin A deficiency (95% CI: -.012, .520, I2 = 94%), and 57.3% had vitamin D deficiency (95% CI: .059, 1.086, I2 = 86%). Calcium deficiency was observed in 125 patients (22.2%, 95% CI: .061, .383, I2 = 97%), and 69.7% had an abnormal parathyroid hormone level (95% CI: .548, .847, I2 = 78%). Ferritin level was abnormal in 30 patients (29.0%, 95% CI: .099, .481, I2 = 79%). CONCLUSIONS: Despite displaying comparable nutrition-related outcomes to mid-term follow-up, our study demonstrated that BPD-DS could result in a high level of long-term nutrition deficiency after BPD-DS for selected patients. However, further randomized controlled studies with standardized supplementation regimens and improvement in compliance are necessary to evaluate and prevent long-term nutritional deficiencies after BPD-DS.

Risk reduction of non-hormonal cancers following bariatric surgery.

Metabolic and bariatric surgery (MBS) is the most effective intervention for weight loss leading to significant resolution of obesity-related medical conditions. Recent literature has demonstrated risk reduction of certain cancer types after MBS. Studies have shown an overall reduction in the risk of hormonal cancer, such as breast and endometrial cancer. However, the association between bariatric surgery and the incidence of various types of non-hormonal cancer such as esophageal, gastric, liver, gallbladder, colorectal, pancreatic and kidney cancer remains contested. The aim of this study was to highlight obesity and its relationship to cancer development as well as bariatric surgery and its role in cancer reduction with focus on non-hormonal cancers.

Technical Success, Sample Adequacy, and Complications of Pediatric Transjugular Liver Biopsy: A Systematic Review and Meta-Analysis.

BACKGROUND: Transjugular liver biopsy (TJLB) procedurally samples liver tissue through the internal jugular vein. It is indicated in the presence of coagulopathies and/or ascites. AIMS: This meta-analysis aimed to assess the safety and efficacy of TJLB in children. METHODS: A literature search of several databases was conducted from inception to August 2022. Eligible studies reported pediatric patients (< 18 years old) who underwent TJLB. The pooled proportion was analyzed using a random-effects model. This review was registered in PROSPERO (CRD42022354421). RESULTS: From 921 initial studies screened, eight met the eligibility criteria, with a total of 361 pediatric patients who underwent 374 TJLBs. All eight studies reported pooled rates of technical success at 99.1% (95% CI 0.982, 1.001; I2 = 0%) and histological adequacy of sampling at 97.5% (95% CI 0.954, 0.995; I2 = 27.66%). A total of 49 complications were reported across six studies, the most common being bleeding from the entry site (38.78%), fevers for less than 24 h (12.24%), red blood cells transfusion requirement (10.2%), supraventricular tachycardia (8.16%), and pain requiring analgesia (8.16%). CONCLUSION: Pediatric TJLB demonstrates high rates of technical success and adequate liver core biopsy samples, with a low rate of complications. These results suggest that TJLB is an effective method for diagnostic yield and postprocedural outcomes, especially in patients with preexisting coagulopathies and ascites where percutaneous liver biopsy is contraindicated. Additional studies evaluating larger groups of pediatric patients may provide further support for the use of TJLB in this population.

Safety and efficacy of LA-ERCP procedure following Roux-en-Y gastric bypass: a systematic review and meta-analysis.

INTRODUCTION: Rapid weight loss following Roux-en-Y gastric bypass surgery (RYGB) translates to an increased need for endoscopic retrograde cholangiopancreatography (ERCP) intervention. Laparoscopically Assisted Transgastric ERCP (LA-ERCP) has emerged to address the issue of accessing the excluded stomach. This study aims to evaluate the safety and efficacy of LA-ERCP procedure following RYGB. METHODS: The Cochrane, EMBASE, SCOPUS, MEDLINE, Daily and Epub databases were searched from inception to May 2022 using the PRISMA guidelines. Eligible studies reported participants older than 18 years who underwent the LA-ERCP procedure, following RYGB, and outcomes of patients. RESULTS: 27 unique studies met the inclusion criteria with 1283 patients undergoing 1303 LA-ERCP procedures. 81.9% of the patients were female and the mean age was 52.18 ± 13.38 years. The rate of concurrent cholecystectomy was 33.6%. 90.9% of procedures were undertaken for a biliary indication. The mean time between RYGB and LA-ERCP was 89.19 months. The most common intervention performed during the LA-ERCP was a sphincterotomy (94.3%). Mean total operative time was 130.48 min. Mean hospital length of stay was 2.697 days. Technical success was 95.3%, while clinical success was 93.8%. 294 complications were recorded with a 20.6% complication rate. The most frequent complications encountered were pancreatitis (6.8%), infection (6.1%), bleeding (3.4%), and perforation (2.5%). Rate of conversion to open laparotomy was 7%. CONCLUSION: This meta-analysis presents preliminary evidence to suggest the safety and efficacy of LA-ERCP procedure following RYGB. Further investigations are warranted to evaluate the long-term efficacy of this procedure using studies with long-term patient follow-up.

Bariatric surgery and left ventricular assist device in patients with heart failure: A systematic review and meta-analysis.

BACKGROUND: The role of metabolic and bariatric surgery (MBS), in synergy with left ventricular assist device (LVAD) implantation, in the scope of end-stage heart failure management for patients with severe obesity is not well elucidated. METHODS: We conducted a meta-analysis using Cochrane, Embase, PubMed, and Scopus databases to include articles from their inception to November 2022. RESULTS: A total of 271 patients who underwent MBS during or after the LVAD implantation were included from eleven separate studies. After surgery, 67.4% of patients were listed on the heart transplant waitlist with 32.5% undergoing a successful transplant. We reported a mean listing time of 13.8 months. Finally, the pooled postoperative complication rate, 30-day readmission rate, and one-year mortality rate were 47.6%, 23.6% and 10.2% respectively. CONCLUSIONS: MBS and LVAD is a safe and effective approach to bridge patients with severe obesity and end-stage heart failure for definitive heart transplantation.

A Novel Approach for the Treatment of Pulmonary Artery Aneurysm Repair Using Inclusion Technique: A Case Report.

Pulmonary artery aneurysm (PAA) is a rare disease with life-threatening complications, especially when accompanied by pulmonary artery hypertension. Due to its rarity, there are currently no specific guidelines for the treatment of PAA. Several surgical techniques have been described to be beneficial in the treatment of PAA originating at the pulmonary trunk. However, several adverse complications have been described for traditional techniques. In this case, we present the first successful repair of PAA with idiopathic pulmonary artery hypertension using a graft inclusion technique.

Seminoma in 46, XY Gonadal Dysgenesis: Rare Presentation and Review of the Literature.

Swyer syndrome is a rare congenital condition that serves as a risk factor for developing germ cell tumors. The condition belongs to the group of 46, XY Disorders of Sexual Development (DSD) is characterized by complete gonadal dysgenesis and is mostly manifested as delayed puberty and primary amenorrhea during adolescence. Individuals with Swyer syndrome are known to be phenotypically female with normal internal and external female genitalia at birth. 46, XY gonadal dysgenesis involves a high risk of gonadoblastoma development with malignant potential such that the onset is greatest at or after the event of puberty. This report of a 12-year-old phenotypic female with 46, XY gonadal dysgenesis, who developed an advanced metastatic seminoma, aims to emphasize the rarity of the development of a seminoma in the context of 46, XY CGD.

Impact on Mid-Term Health-Related Quality of Life after Duodenal Switch: a Systematic Review and Meta-Analysis.

PURPOSE: Metabolic and bariatric surgery (MBS) could improve health-related quality of life (HrQoL) for selected patients with obesity. Although biliopancreatic diversion with duodenal switch (BPD-DS) is regarded as the most effective MBS technique in achieving weight loss, no consensus has been reached on the impact of BPD-DS on HrQoL. The aim of this meta-analysis is to assess the mid-term HrQoL after BPD-DS in the management of patients with obesity. MATERIALS AND METHODS: Cochrane, Embase, APA PsycInfo, PubMed, Scopus, and Web of Science were searched for articles from their inception to August 2022 by two independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) system. The review was registered prospectively with PROSPERO (CRD42022352073). RESULTS: From 223 studies screened, twelve studies met the eligibility criteria, with a total of 937 patients with obesity undergoing BPD-DS. Minimal clinically important differences (MCID) were reached for the physical component summary score (PCS) of the 36-Item Short-Form Health Survey (SF-36) (MD = 13.4) and impact of weight on quality of life (IWQOL)-Lite total score (MD = 48.7). Similarly, MCIDs were attained in the Laval questionnaire and SF-36 subscales. CONCLUSION: Our meta-analysis demonstrated an improvement in mid-term HrQoL after BPD-DS. Despite the promising trends demonstrated in this meta-analysis, further studies with large sample sizes are needed to evaluate the impact of HrQoL on patients with obesity after BPD-DS.

Update on the efficacy and safety of intravenous tranexamic acid in hip fracture surgery: a systematic review and meta-analysis.

AIM: The aim of this meta-analysis was to assess the safety and efficacy of tranexamic acid (TXA) in the management of hip fracture surgeries in comparison with placebo. METHODS: A systematic search was conducted from August 6, 2021. Eligible studies included randomized clinical trials and prospective studies comparing the use of intravenous TXA in patients treated for hip fractures, in comparison with placebo. Review Manager was used for the meta-analysis. RESULTS: Eighteen prospective studies including 14 RCTs met the eligibility criteria. The results favored the TXA group in the quantity of total blood loss (MD = - 196.91 mL, 95% CI - 247.59, - 146.23, I2 = 92%), intraoperative blood loss (MD = - 26.86 mL, 95% CI - 36.96, - 16.78, I2 = 62%), and rate of blood transfusion (OR 0.35, 95% CI 0.28, 0.42, I2 = 0%). TXA also exhibited higher hemoglobin level at day 1 (MD = 6.77 g/L, 95% CI 4.30, 9.24, I2 = 83%) and day 3 (MD = 7.02 g/L, 95% CI 3.30, 10.74, I2 = 82%) postoperatively. There was no significant difference found in the incidence of thromboembolic events from occurring between the two groups, such as deep vein thrombosis (OR 1.22, 95% CI 0.73, 2.02, I2 = 0%) and pulmonary embolism (OR 0.82, 95% CI 0.33, 2.05, I2 = 0%). CONCLUSION: Administration of intravenous TXA appears to reduce blood loss, rate of blood transfusions and pose no increased risk of thromboembolic events. Therefore, TXA should be considered by physicians when managing hip fracture patients.

Open Versus Laparoscopic Surgery in the Management of Adrenocortical Carcinoma: A Systematic Review and Meta-analysis.

BACKGROUND: Laparoscopic surgery is considered a standard treatment for benign adrenal tumors; however, no consensus has been reached on the optimal resection technique for adrenocortical carcinomas. This study aims to evaluate the safety and efficacy of laparoscopic surgery and open surgery in the management of adrenocortical carcinoma. METHODS: The Cochrane, Embase, PubMed, Scopus, and Web of Science databases were searched for articles from inception to May 2022, by two independent reviewers using the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. The review was registered prospectively on the PROSPERO database (CRD42022316050). RESULTS: From 183 studies screened, 11 studies met the eligibility criteria, with a total of 1617 patients with adrenocortical carcinoma undergoing either laparoscopic surgery (n = 472) or open surgery (n = 1145). Open surgery demonstrated a lower rate of positive resection margin compared with laparoscopic surgery (odds ratio [OR] 1.52, 95% confidence interval [CI] 1.10-2.10; I2 = 0%). Additionally, open surgery had more favorable overall survival (OR 0.56, 95% CI 0.44-0.72; I2 = 0%) and recurrence-free rates (OR 0.60, 95% CI 0.42-0.85; I2 = 38%) than laparoscopic surgery at 3 years. Hospital stay was shorter for laparoscopic surgery than open surgery (mean difference - 2.49 days, 95% CI - 2.95 to - 2.04; I2 = 45%). CONCLUSIONS: Open surgery should still be considered the standard operative approach; however, laparoscopic surgery could be regarded as an effective and safe operation for selected adrenocortical carcinoma cases with appropriate laparoscopic expertise. Further randomized controlled studies with tumor stage- and resection margin-dependent survival analysis are necessary to ascertain the safety and efficacy of the treatment.

Risk of non-hormonal cancer after bariatric surgery: meta-analysis of retrospective observational studies.

BACKGROUND: Obesity is associated with an increased incidence of at least 13 types of cancer. Although bariatric surgery has been associated with a reduced risk of hormonal cancers, data for non-hormonal cancers are scarce. The aim of this study was to evaluate the effect of bariatric surgery on the incidence of non-hormonal cancers. METHODS: Cochrane, Embase, PubMed, Scopus, and Web of Science were searched for articles between 1984 and 2018, following the PRISMA system. Meta-analysis was conducted using a random-effect model with subgroup analysis by procedure and cancer type. RESULTS: From 2526 studies screened, 15 were included. There were a total of 18 583 477 patients, 947 787 in the bariatric group and 17 635 690 in the control group. In comparison to the non-surgical group, the bariatric group had a lower incidence of cancer (OR .65 (95 per cent c.i. 0.53 to 0.80); P < 0.002). In the subgroup analysis, Roux-en-Y gastric bypass and sleeve gastrectomy were associated with decreased risk of developing cancer, while no difference was observed with adjustable gastric banding. When evaluated by cancer type, liver (OR 0.417 (95 per cent c.i. 0.323 to 0.538)), colorectal (OR 0.64 (95 per cent c.i. 0.49 to 0.84)), kidney and urinary tract cancer (OR 0.77 (95 per cent c.i. 0.72 to 0.83)), oesophageal (OR 0.60 (95 per cent c.i. 0.43 to 0.85)), and lung cancer (OR 0.796 (95 per cent c.i. 0.45 to 0.80)) also presented a lower cancer incidence in the bariatric group. CONCLUSION: Bariatric surgery is related to an almost 50 per cent reduction in the risk of non-hormonal cancers.

Single Versus Double Anastomosis Duodenal Switch in the Management of Obesity: A Meta-analysis and Systematic Review.

BACKGROUND: Biliopancreatic diversion with duodenal switch (BPD-DS) is an effective yet technically challenging bariatric surgery with many complications. Alternatively, single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) was recently introduced as a simplified bariatric procedure. This meta-analysis aimed to assess the safety and efficacy of SADI-S compared with BPD-DS in the management of patients with obesity. METHODS: Cochrane, Embase, PubMed, Scopus, and Web of Science were searched for articles from their inception to May 2022 by 2 independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis system. The review was registered prospectively with PROSPERO (CRD42022333521). RESULTS: From 123 studies screened, 6 studies met the eligibility criteria, with a total of 1847 patients with obesity undergoing either SADI-S (n=818) or BPD-DS (n=1029). Preoperative body mass index was similar between the 2 groups, and the BPD-DS group had a greater % excess body mass index loss (EBMIL) (MD=-10.16%, 95% confidence interval: -11.80, -8.51, I 2 =0%) at 2 years compared with the SADI-S group. There was no difference observed in preoperative comorbidities and remission, including diabetes, hypertension, and dyslipidemia between SADI-S and BPD-DS cohorts. Compared with BPD-DS, SADI-S had shorter hospital stays (MD=-1.36 d, 95% CI: -2.39, -0.33, I 2 =86%), and fewer long-term (>30 d) complications (OR=0.56, 95% CI: 0.42, 0.74, I 2 =20%). Conversely, among nutritional deficiency outcomes, the SADI-S group had few patients with abnormal vitamin D (OR=0.51, 95% CI: 0.36, 0.72, I 2 =0%) values than the BPD-DS group. CONCLUSIONS: SADI-S has shown to be a possible alternative treatment option to BPD-DS in managing patients with obesity. Despite the promising results, further randomized controlled studies with more extended follow-up periods are necessary to ascertain the safety and efficacy of the treatment.

Open versus laparoscopic surgery in the management of patients with gallbladder cancer: A systematic review and meta-analysis.

BACKGROUND: The aim of this meta-analysis was to assess the safety and efficacy of laparoscopic surgery when compared to open surgery in the management of gallbladder cancer. METHODS: Ovid Cochrane Library, Medline, Embase, Epub, and Scopus were searched. A meta-analysis of selected studies was performed, and a subgroup analysis was performed by tumor stage. RESULTS: Fourteen studies met the eligibility criteria with a total of 1792 participants undergoing either laparoscopic or open surgery. Survival rate of laparoscopic group was higher than open group at T2 tumor stage after 1 year (OR = 2.130, 95%CI: 1.372, 3.306, I2 = 0%) and 2 year (OR = 2.074, 95%CI: 1.411, 3.050, I2 = 0%) as well as T3 tumor stage after 1 year (OR = 2.805, 95%CI: 1.631, 4.826, I2 = 0%) and 2 year (OR = 2.453, 95%CI: 1.367, 4.400, I2 = 0%). Additionally, overall recurrence rate between laparoscopic and open cohorts was similar (OR: 1.098, 95%CI: 0.774, 1.558, I2 = 5.56%). CONCLUSION: In comparison to open surgery, the results seem to show a trend favoring laparoscopic surgery as a possible alternative treatment option to commence the management of gallbladder cancer.
