BACKGROUND
Advancements in surgical techniques have improved outcomes in patients undergoing pancreatic surgery. To date there have been no meta-analyses comparing robotic and laparoscopic approaches for distal pancreatectomies (DP) in patients with pancreatic adenocarcinoma (PDAC). This systematic review and network meta-analysis aims to explore the oncological outcomes of laparoscopic distal pancreatectomy (LDP), robotic distal pancreatectomy (RDP) and open distal pancreatectomy (ODP).
METHODS
A systematic search was conducted for studies reporting laparoscopic, robotic or open surgery for DP. Frequentist network meta-analysis of oncological outcomes (overall survival, resection margins, tumor recurrence, examined lymph nodes, administration of adjuvant therapy) were performed.
RESULTS
Fifteen studies totalling 9,301 patients were included in the network meta-analysis. 1,946, 605 and 6,750 patients underwent LDP, RDP and ODP respectively. LDP (HR: 0.761, 95% CI: 0.642-0.901, = 0.002) and RDP (HR: 0.757, 95% CI: 0.617-0.928, = 0.008) were associated with overall survival (OS) benefit when compared to ODP. LDP (HR: 1.00, 95% CI: 0.793-1.27, = 0.968) was not associated with OS benefit when compared to RDP. There were no significant differences between LDP, RDP and ODP for resection margins, tumor recurrence, examined lymph nodes and administration of adjuvant therapy.
CONCLUSION
This study highlights the longer OS in both LDP and RDP when compared to ODP for patients with PDAC.

Meta-Analysis
This systematic review and meta-analysis addresses the effects of minimally invasive surgical techniques, specifically the Reverdin Isham osteotomy, on functional and radiological outcomes in patients with moderate Hallux Valgus, a common foot deformity. The review included randomized and non-randomized controlled trials, as well as case reports, assessing the osteotomy in adults with moderate to severe Hallux Valgus. Searches were conducted in electronic databases such as MEDLINE and Web of Science up until July 2023, and the Joanna Briggs Institute's critical appraisal tool was used to assess the risk of bias. Meta-analytical analyses employed a random-effects model with small-sample correction, presenting results as standardized mean differences and mean differences with 95% confidence intervals. Seven studies involving 554 patients and 643 operated feet were included, showing significant improvements in AOFAS scores (an average improvement of 36 points from 28.61 to 45.16) and reductions in radiological angles such as the distal metatarsal angle and hallux valgus angle post-surgery (IMA improved by - 3.07° from - 4.68 to - 1.46, DMAA by - 6.12° from - 9.52 to - 2.71, and HVangle by - 15.27° from - 17.98 to - 12.57). Despite these positive outcomes, most studies exhibited risks of bias and other methodological limitations, impacting the generalizability of the results. Overall, the findings highlight the efficacy of the Reverdin Isham osteotomy in improving both functional and radiological parameters in patients with moderate Hallux Valgus, although further research is warranted to solidify these results. No specific funding was received for this study, and the protocol was registered on PROSPERO with the number CRD-42023445886.

Review
Several regional anesthesia (RA) techniques have been described for distal upper limb surgery. However, the best approach in terms of RA block success rate and safety is not well recognized. To assess and compare the surgical anesthesia and efficacy of axillary brachial plexus block with other RA techniques for hand and wrist surgery. The attainment of adequate surgical anesthesia 30 min after block placement was considered a primary outcome measure. Additionally, successful block outcomes were required without the use of supplemental local anesthetic injection, systemic opioid analgesia, or the need to convert to general anesthesia. We performed a systematic search in the following databases: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and CENTRAL. RCTs comparing axillary blocks with other brachial plexus block techniques, distal peripheral forearm nerve block, intravenous RA, and the wide-awake local anesthesia no tourniquet (WALANT) technique were included. In total, 3070 records were reviewed, of which 28 met the inclusion criteria. The meta-analysis of adequate surgical anesthesia showed no significant difference between ultrasound-guided axillary block and supraclavicular block (RR: 0.94 [0.89, 1.00]; = 0.06; I = 60.00%), but a statistically significant difference between ultrasound-guided axillary block and infraclavicular block (RR: 0.92 [0.88, 0.97]; < 0.01; I = 53.00%). Ultrasound-guided infraclavicular blocks were performed faster than ultrasound-guided axillary blocks (SMD: 0.74 [0.30, 1.17]; < 0.001; I = 85.00%). No differences in performance time between ultrasound-guided axillary and supraclavicular blocks were demonstrated. Additionally, adequate surgical anesthesia onset time was not significantly different between ultrasound-guided block approaches: ultrasound-guided axillary blocks versus ultrasound-guided supraclavicular blocks (SMD: 0.52 [-0.14, 1.17]; = 0.12; I = 86.00%); ultrasound-guided axillary blocks versus ultrasound-guided infraclavicular blocks (SMD: 0.21 [-0.49, 0.91]; = 0.55; I = 92.00%). The RA choice should be individualized depending on the patient, procedure, and operator-specific parameters. Compared to ultrasound-guided supraclavicular and infraclavicular block, ultrasound-guided axillary block may be preferred for patients with significant concerns of block-related side effects/complications. High heterogeneity between studies shows the need for more robust RCTs.

OBJECTIVE
Urolithiasis is a common urological diseases and affects the daily life of patients. Medical expulsive therapy has become acceptable for many parents. We conducted a meta-analysis to determine the efficacy and safety of tadalafil compared with tamsulosin for treating distal ureteral stones less than 10 mm in length.
METHODS
Related studies were identified via searches of the PubMed, Embase, and Cochrane Library databases. All the articles that described the use of tadalafil and tamsulosin for treating distal ureteral stones were collected.
RESULTS
A total of 14 studies were included in our meta-analysis. Our results revealed that tadalafil enhanced expulsion rate [odds ratio (OR) = 0.68, 95% confidence interval (CI): 0.47 to 0.98, = 0.04]; reduced expulsion time [mean difference (MD) = 1.22, 95% CI (0.13, 2.30), = 0.03]; lowered analgesia use [MD = 38.66, 95% CI (7.56, 69.77), = 0.01] and hospital visits [MD = 0.14, 95% CI (0.06, 0.22), = 0.0006]. According to our subgroup analysis, either tadalafil 5 mg or 10 mg did not promote expulsion rate and accelerate expulsion time compared with tamsulosin. But patients receiving 5 mg tadalafil decreased analgesia usage [MD = 101.04, 95% CI (67.56, 134.01), < 0.00001].
CONCLUSION
Compared with tamsulosin, tadalafil demonstrates a higher expulsion rate and less expulsion time for patients with distal ureteral stones less than 10 mm with a favorable safety profile.

Review
BACKGROUND AND AIMS
Serrated polyps (SPs) are precursors to 15-20% of colorectal cancers (CRCs). However, there are uncertainties regarding which SPs require surveillance and at what intervals, with recommendations adapted from those for adenomas in the absence of solid evidence. Our aim was to assess which SP risk characteristics relate to a higher risk of metachronous CRC or advanced polyps.
METHODS
We systematically searched PubMed, EMBASE, and Cochrane for cohort, case-control studies, and clinical trials from inception to Dec 31, 2023, for CRC or advanced polyps [advanced adenoma (AA) or advanced SP] incidence at surveillance stratified by baseline SP size, dysplasia, location, and multiplicity. We defined advanced SPs as those >10mm or with dysplasia. CRC and advanced polyp incidence per 1,000 person-years (p-y) were estimated. We performed a meta-analysis by calculating pooled relative risks (RR) using a random-effects model.
RESULTS
5,903 studies were reviewed and 14 included, with 493,949 patients (mean age 59·5 years, 55% men). Mean follow-up was 4·9 years. CRC incidence per 1,000 p-y was 2·09 (95%CI 1·29-2·90) for advanced SP, 1·52 (0·78-2·25) for SP>10mm, 5·86 (2·16-9·56) for SP with dysplasia, 1·18 (0·77-1·60) for proximal SP, 0·52 (0·08-1·12) for >3SP, 0·50 (0·35-0·66) for non-advanced SP, and 0·44 (0·41-0·46) for normal colonoscopy. Metachronous CRC risk was higher in advanced SP vs non-advanced SP (RR 1·84, 95%CI 1·11-3·04), and vs normal colonoscopy (RR 2·92, 2·26-3·77); in SP>10mm vs <10mm (RR 2·61, 1·43-4·77), and vs normal colonoscopy (RR 3·52, 2·17-5·69); and in SP with dysplasia vs normal colonoscopy (RR 2·71, 2·00-3·67). No increase in CRC or advanced polyp risk was found in patients with proximal vs distal SP, nor in >3SP vs 1-2SP.
CONCLUSIONS
CRC risk is significantly higher in patients with baseline advanced SP after 4·9 years of follow-up, with risk magnitudes similar to those described for AA, supporting the current recommendation for 3-year surveillance in patients with advanced SP.

BACKGROUND
Posttraumatic wrist osteoarthritis is an irreversible and often progressive condition. Many surgical treatments, used in (daily) practice, aim to relieve symptoms like pain and restore function. The aim of this systematic review is to assess the patient reported and functional outcomes of the most common surgical interventions in patients with posttraumatic wrist osteoarthritis. This overview can help clinicians select the best treatment and manage patient's expectations.
METHODS
A literature search was performed in Pubmed, Embase and Cochrane for articles published between 1990 and November 2022 according to the PRISMA guidelines. The study protocol has been registered in the PROSPERO database (CRD42017080427). Studies that describe patient reported outcomes (pain and Disability of Arm, Shoulder and Hand (DASH) -score) and functional outcomes (range of motion (ROM) and grip strength) after surgical intervention with a minimal follow-up of 1 year were included. The identified surgical procedures included denervation, proximal row carpectomy, interpositional- and total arthroplasty, and midcarpal-, radiocarpal- and total arthrodesis. The pre-and postoperative outcomes were pooled and presented per salvage procedure.
RESULTS
Data from 50 studies was included. Pain score improved after all surgeries except denervation. Flexion/extension decreased after radiocarpal arthrodesis, did not show significant changes after proximal row carpectomy, and improved for all other surgeries. DASH score improved after arthroplasty, proximal row carpectomy and midcarpal arthrodesis. Grip strength improved after interposition arthroplasty and partial arthrodesis.
CONCLUSION
Evidence from this review did not support the indication for denervation in this particular patient population. In patients with SLAC/SNAC II, proximal row carpectomy might be favourable to a midcarpal arthrodesis solely based on better FE ROM of the radiocarpal joint after proximal row carpectomy. In terms of radiocarpal mobility, total wrist arthroplasty might be preferred to radiocarpal arthrodesis in patients with osteoarthritis after a distal radius fracture. More uniform measurements of outcomes would improve the understanding of the effect of surgical treatments of the posttraumatic osteoarthritic wrist.

BACKGROUND
Diabetic foot ulcers (DFUs) are serious complications that induce a high risk of lower extremity amputations and mortality. Compared with the standard of care, few reports analyzed the outcome of surgical treatment mainly for diabetic toe deformities and ulcers. The aim of this study is to collate evidence on the outcomes of interphalangeal resection arthroplasty (IP-RA) in preventing and treating diabetic toe ulcers distal to the metatarsophalangeal joint.
METHODS
A search strategy has been developed including electronic databases from inception. Only ulcers distal to the metatarsophalangeal joints were included. Noninfected and infected ulcers were also included at any toe location (dorsal/side/plantar). Outcomes were defined as healing rate, time to heal, ulcer recurrence, ulcer transfer, postintervention infection, wound dehiscence, and additional surgeries including amputation. Proportional meta-analysis was conducted for frequency outcomes.
RESULTS
Six observational studies comprising 217 patients with 244 IP-RA procedures were included. The mean follow-up period was 23.4 ± 8.2 months. Weighted frequencies were as follows: healing rate (93.6%), ulcer recurrence frequency (4.3%), ulcer transfer frequency (15.4%), postoperative infection (10.5%), wound dehiscence (17.8%), revision surgery (5%), and amputation rate (3.4%). The mean healing time was 4.3 ± 1.8 weeks.
CONCLUSION
This review suggests that IP-RA is effective in preventing and treating diabetic toe deformities and ulcers with a modest rate of complications for this specific and often challenging clinical presentation.

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
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.

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.
