Review
Pancreatoduodenectomy, the primary surgical strategy for managing cholangiocarcinoma, is executed via two distinct methodologies, namely minimally invasive pancreatoduodenectomy (MIPD) and open pancreatoduodenectomy (OPD). The selection between these surgical options is critical, as it directly influences patient outcomes, encompassing both short-term recovery metrics and long-term survival rates. Despite the clinical significance of these procedures, there exists a notable void in the literature regarding a comprehensive comparison of MIPD and OPD, particularly in assessing their respective efficacies and complications. This lack of detailed comparative analysis has left a gap in evidence-based guidance for clinicians faced with the decision of choosing the most appropriate surgical approach for their patients. The absence of robust data comparing the two techniques underscores the necessity for a meta-analysis that rigorously examines and contrasts the outcomes associated with MIPD and OPD. By drawing upon a wide array of international studies, this research aims to shed light on the advantages and potential drawbacks of each method, thereby providing a more informed basis for surgical decision-making in the treatment of cholangiocarcinoma.

Meta-Analysis Review
PURPOSE
A history of fractures involving the distal radius, proximal humerus, spine, and hip may be associated with the incidence of subsequent hip fractures in older people. However, a comprehensive summary of this association using a rigorous methodology is lacking. Our objective was to systematically review the literature and examine the association between four major osteoporotic fractures and subsequent hip fractures in individuals aged ≥ 50 years.
METHODS
We searched MEDLINE, Embase, CENTRAL, ICTRP, and ClinicalTrials.gov on February 15, 2023. The search included cohort or case-control studies investigating the association between these four types of osteoporotic fractures and subsequent hip fractures. We pooled the hazard ratios (HRs) with 95% confidence intervals (CI) using the random-effects model. We used the Quality In Prognosis Studies tool to assess the risk of bias in the included studies, and the grading of recommendations assessment, development, and evaluation approach to determine the certainty of evidence.
RESULTS
The selection process identified 48 studies for qualitative synthesis and 23 studies (2,239,217 participants) for meta-analysis. The overall methodological quality had a low risk of bias in 65% of the included studies. The association between a history of major osteoporotic fractures and subsequent hip fracture varied, with a high certainty of evidence for a history of proximal humerus and hip fractures (HR 2.02, 95% CI 1.75-2.33 and 2.86, 95% CI 1.92-4.25, respectively), moderate certainty for distal radius fractures (HR 1.66, 95% CI 1.53-1.81), and low certainty for spine fractures (HR 1.53, 95% CI 1.38-1.69).
CONCLUSIONS
In conclusion, a history of major osteoporotic fractures, particularly distal radius, proximal humerus, and hip fractures, is associated with subsequent hip fractures in older adults. Further research is needed to verify the association between a history of spine fracture and subsequent hip fractures.

Meta-Analysis
Effect of artificial or autologous coverage of the pancreatic remnant or anastomosis on postoperative pancreatic fistulas after partial pancreatectomy: meta-analysis of randomized clinical trials.
BACKGROUND
Postoperative pancreatic fistulas remain a driver of major complications after partial pancreatectomy. It is unclear whether coverage of the anastomosis or pancreatic remnant can reduce the incidence of postoperative pancreatic fistulas. The aim of this study was to evaluate the effect of autologous or artificial coverage of the pancreatic remnant or anastomosis on outcomes after partial pancreatectomy.
METHODS
A systematic literature search was performed using MEDLINE and the Cochrane Central Register of Controlled Trials (CENTRAL) up to March 2024. All RCTs analysing a coverage method in patients undergoing partial pancreatoduodenectomy or distal pancreatectomy were included. The primary outcome was postoperative pancreatic fistula development. Subgroup analyses for pancreatoduodenectomy or distal pancreatectomy and artificial or autologous coverage were conducted.
RESULTS
A total of 18 RCTs with 2326 patients were included. In the overall analysis, coverage decreased the incidence of postoperative pancreatic fistulas by 29% (OR 0.71, 95% c.i. 0.54 to 0.93, P < 0.01). This decrease was also seen in the 12 RCTs covering the remnant after distal pancreatectomy (OR 0.69, 95% c.i. 0.51 to 0.94, P < 0.02) and the 4 RCTs applying autologous coverage after pancreatoduodenectomy and distal pancreatectomy (OR 0.53, 95% c.i. 0.29 to 0.96, P < 0.04). Other subgroup analyses (artificial coverage or pancreatoduodenectomy) showed no statistically significant differences. The secondary endpoints of mortality, reoperations, and re-interventions were each affected positively by the use of coverage techniques. The certainty of evidence was very low to moderate.
CONCLUSION
The implementation of coverage, whether artificial or autologous, is beneficial after partial pancreatectomy, especially in patients undergoing distal pancreatectomy with autologous coverage.

Dorsal bridge plating (DP) of the distal radius is used as a definitive method of stabilization in complex fracture configurations and polytrauma patients. This review aims to summarize the current understanding of DP and evaluate surgical outcomes. Four databases were searched following the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines and registered with PROSPERO. Papers presenting outcome or complication data for DP were included. These were reviewed using the National Institutes of Health Quality Assessment and Methodological Index for Non-Randomised Studies tools. Results were collated and compared to a local cohort of DP patients. Literature review identified 416 patients with a pooled complication rate of 17% requiring additional intervention. The most prevalent complications were infection/wound healing issues, arthrosis, and hardware failure. Average range of motion was flexion 46.5 degrees, extension 50.7 degrees, ulnar deviation 21.4 degrees, radial deviation 17.3 degrees, pronation 75.8 degrees, and supination 72.9 degrees. On average, DP removal occurred at 3.8 months. Quality assessment showed varied results. There were 19 cases in our local cohort. Ten displayed similar results to the systematic review in terms of range of motion and radiographic parameters. Higher QuickDASH scores and complication rates were noted. Local DP showed earlier plate removal at 2.9 months compared to previous studies. DP is a valid and useful technique for treating complex distal radius fractures. It displays a lower risk of infection and pain compared to external fixation which is commonly used to treat similar injuries. Patients can recover well following treatment both in function and range of motion. Further high-quality studies are required to fully evaluate the technique.

Facial synkinesis is characterized by unintentional contractions of facial musculature secondary to aberrant facial nerve healing. The associated impairment in facial functioning results in a significant decrease in patients' quality of life. The mainstay treatment for postfacial paralysis synkinesis (PFPS) is chemodenervation and physiotherapy, which requires long-term maintenance neurotoxin injections. This can lead to treatment resistance. Selective neurectomy of the distal branches of the facial nerve has been suggested as an effective surgical treatment of PFPS. This study aims to provide a comprehensive systematic review evaluating the efficacy of selective neurectomy for patients presenting with PFPS. Ovid MEDLINE, Ovid Embase, PubMed, Web of Science, and CINAHL were searched from inception until July 2022. Studies that investigated postoperative outcomes of pediatric and/or adult patients who underwent selective neurectomy as a treatment for PFPS were included. The database search identified 1,967 studies, and 11 were ultimately included based on inclusion and exclusion criteria. These 11 studies represented 363 patients. Studies reported on outcomes following selective neurectomy with or without adjuvant therapies for patients with PFPS. The main outcome categories identified were clinician-reported outcomes and patient-reported outcomes. The studies that used clinician-reported outcomes found an improvement in both synkinesis and facial nerve paralysis (FNP) outcomes following selective neurectomy according to their respective grading systems. Three studies looked at patient-reported outcomes and found increased patient-reported quality of life and satisfaction following selective neurectomy. The most reported complications were upper lip contracture, uneven cheek surface, lagophthalmos, and temporary oral incompetence. Selective neurectomy has demonstrated stable or improved synkinesis, FNP, and quality of life outcomes in patients with PFPS. This approach should be considered for patients with PFPS, particularly for patients with refractory symptoms or those who are unable to undergo continued medical management.

Review
Obesity is a grave concern within the United States, resulting in lost productivity, increased medical costs, and comorbidities with lifelong repercussions. The laparoscopic sleeve gastrectomy is a treatment option for obesity. The following meta-analysis sought to combine adolescent and adult literature to determine the overall effect of the sleeve gastrectomy on weight loss, to evaluate the effect of age at the time of surgery on weight loss, and to describe and explore variation in weight loss by sample characteristics. Overall weight loss was assessed at proximal and distal points, a dichotomous moderator variable analysis was conducted with subjects ≤21 years of age and >21 years of age, and a meta-regression assessing % male, % female, and baseline BMI was conducted to assess moderator variables. The laparoscopic sleeve gastrectomy was effective at facilitating weight loss with effect sizes varying from 0.916 to2.816. Age, biological sex, and baseline BMI were not found to have an impact on weight loss. The clinical consequences of prolonged obesity are evident and earlier intervention may be justified to counter the long-term effects caused by obesity related comorbidities. Standardized reporting of comorbidities and the effect of bariatric surgery on comorbid conditions is essential to allow further analysis.

Review
Molar distalization is used to correct molar relationships or to create space for mild anterior crowding. However, whether clear aligners can provide proper vertical control with the sequential distalization strategy has been highly debated. Thus, the current study aimed to systematically review the amount of dentoskeletal changes in the vertical dimension that results from sequential molar distalization in clear aligner therapy without temporary anchorage devices (TADs). Registered with PROSPERO (CRD42023447211), relevant original studies were screened from seven databases and supplemented by a manual search by two investigators independently. Articles were screened against inclusion and exclusion criteria, and a risk of bias assessment was conducted for each included article. Relevant data were extracted from the included articles and meta-analysis was performed using RStudio. Eleven articles (nine for maxillary distalization and two for mandibular distalization) were selected for the final review. All studies have a high or medium risk of bias. For maxillary molar distalization, the meta-analysis revealed 0.26 mm [0.23 mm, 0.29 mm] of maxillary first molar intrusion based on post-distalization dental model analysis, as well as 0.50 mm [-0.78 mm, 1.78 mm] of maxillary first molar intrusion and 0.60 mm [-0.42 mm, 1.62 mm] of maxillary second molar intrusion based on post-treatment lateral cephalometric analysis. Skeletally, there was a -0.33° [-0.67°, 0.02°] change in the SN-GoGn angle, -0.23° [-0.30°, 0.75°] change in the SN-MP angle, and 0.09° [-0.83°, 1.01°] change in the PP-GoGn angle based on post-treatment lateral cephalometric analysis. There was insufficient data for meta-analysis for mandibular molar distalization. No significant changes in vertical dimension were observed, both dentally and skeletally, after maxillary molar distalization with a sequential distalization strategy. However, further studies on this topic are needed due to the high risk of bias in the currently available studies.

(Review)
Review
The aim of this study is to compare the time and movement of orthodontic treatment using dental anchorage and skeletal anchorage in adolescent and adult patients with dental malocclusions. A systematic search was conducted in the Embase, PubMed, Lilacs, Cochrane, Trip, and Scopus databases up to October 2022. All the articles were selected using title and abstract, applying the inclusion and exclusion criteria. Disagreements were resolved with a third author. Finally, a full-text selection took place. The data extraction was conducted by two authors who independently evaluated the risk of bias. The methodological quality of the randomized clinical trials was evaluated using the Cochrane tool for the evaluation of the randomized clinical trials. Six articles were included in the data analysis. There were four clinical trials and two randomized clinical trials. A total of 176 patients was obtained with an age range between 14 and 46 years. Four studies showed significant differences when comparing the two anchorages in retraction or distalization of tooth groups, and two showed no differences when using dental and skeletal anchorage for vertical movements; only the articles with vertical movements showed relapse. We can conclude that skeletal anchorage generates precise and stable horizontal movements without overloading or changing the position of the molar. Future studies must incorporate three-dimensional technology for greater clinical accuracy.

Review
OBJECTIVE
The objective of this review is to assess the effect of total maxillary arch distalization (TMAD) treatment on the dental, skeletal, soft tissues, and airways during non-extraction camouflage treatment of class II division 1 patients.
METHODS
We performed a systematic review of the published data in four electronic databases up to April 2023. We considered studies for inclusion if they were examining the effects of TMAD during treatment of class II division 1 malocclusion in the permanent dentition. Study selection, data extraction, risk of bias assessment, and assessment of the strength of the evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool were performed in duplicate.
RESULTS
Out of the 27 articles that met the initial eligibility criteria, 19 studies were finally selected. Fair to relatively good quality evidence was identified after the risk of bias assessment of the included studies. Out of the 19 selected studies, 5 studies used inter-radicular TADs, 10 studies used modified C- palatal plate (MCPP), 3 studies used infra zygomatic crest (IZC) TADs, 1 study compared buccal TADs versus MCPP, and 1 study compared between cervical headgear and MCPP. The maximum amount of maxillary arch distalization using buccal TADs, MCPP, IZC TADs, and headgear was 4.2mm, 5.4mm, 5mm, and 2.5mm respectively. Different results regarding the amount of dental, skeletal, and soft tissue changes were observed.
CONCLUSIONS
The current low to very low certainty level of evidence suggests that TMAD is effective in camouflaging class II division 1 malocclusion. Future well-conducted and clearly reported randomized controlled trials that include a control group are needed to make robust recommendations regarding the effect of TMAD with different appliances on dental, skeletal, and soft tissue structures.
CLINICAL RELEVANCE
TMAD should be given priority with caution in class II patients who refuse the extraction of premolars. TMAD may be considered an adjunctive approach to solve cases associated with high anchorage need or anchorage loss.

Surgical Endoscopy Jun 2024This study compared the cost-effectiveness of open (ODP), laparoscopic (LDP), and robotic (RDP) distal pancreatectomy (DP). (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
This study compared the cost-effectiveness of open (ODP), laparoscopic (LDP), and robotic (RDP) distal pancreatectomy (DP).
METHODS
Studies reporting the costs of DP were included in a literature search until August 2023. Bayesian network meta-analysis was conducted, and surface under cumulative ranking area (SUCRA) values, mean difference (MD), odds ratio (OR), and 95% credible intervals (CrIs) were calculated for outcomes of interest. Cluster analysis was performed to examine the similarity and classification of DP approaches into homogeneous clusters. A decision model-based cost-utility analysis was conducted for the cost-effectiveness analysis of DP strategies.
RESULTS
Twenty-six studies with 29,164 patients were included in the analysis. Among the three groups, LDP had the lowest overall costs, while ODP had the highest overall costs (LDP vs. ODP: MD - 3521.36, 95% CrI - 6172.91 to - 1228.59). RDP had the highest procedural costs (ODP vs. RDP: MD - 4311.15, 95% CrI - 6005.40 to - 2599.16; LDP vs. RDP: MD - 3772.25, 95% CrI - 4989.50 to - 2535.16), but incurred the lowest hospitalization costs. Both LDP (MD - 3663.82, 95% CrI - 6906.52 to - 747.69) and RDP (MD - 6678.42, 95% CrI - 11,434.30 to - 2972.89) had significantly reduced hospitalization costs compared to ODP. LDP and RDP demonstrated a superior profile regarding costs-morbidity, costs-mortality, costs-efficacy, and costs-utility compared to ODP. Compared to ODP, LDP and RDP cost $3110 and $817 less per patient, resulting in 0.03 and 0.05 additional quality-adjusted life years (QALYs), respectively, with positive incremental net monetary benefit (NMB). RDP costs $2293 more than LDP with a negative incremental NMB but generates 0.02 additional QALYs with improved postoperative morbidity and spleen preservation. Probabilistic sensitivity analysis suggests that LDP and RDP are more cost-effective options compared to ODP at various willingness-to-pay thresholds.
CONCLUSION
LDP and RDP are more cost-effective than ODP, with LDP exhibiting better cost savings and RDP demonstrating superior surgical outcomes and improved QALYs.
