Review
OBJECTIVES
Colorectal endoscopic submucosal dissection (ESD) is a technically complex procedure. The scissor knife mechanism may potentially provide easier and safer colorectal ESD. The aim of this meta-analysis is to evaluate the efficacy and safety of scissor-assisted vs. conventional ESD for colorectal lesions.
METHODS
A search strategy was conducted in MEDLINE, Embase, and Lilacs databases from January 1990 to November 2023 according to PRISMA guidelines. Fixed and random-effects models were used for statistical analysis. Heterogeneity was assessed using I test. Risk of bias was assessed using the ROBINS-I and RoB-2 tools. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation tool.
RESULTS
A total of five studies (three retrospective and two randomized controlled trials, including a total of 1575 colorectal ESD) were selected. The intraoperative perforation rate was statistically lower (risk difference [RD] -0.02; 95% confidence interval [CI] -0.04 to -0.01; P = 0.001; I = 0%) and the self-completion rate was statistically higher (RD 0.14; 95% CI 0.06, 0.23; P = 0.0006; I = 0%) in the scissor-assisted group compared with the conventional ESD group. There was no statistical difference in R0 resection rate, en bloc resection rate, mean procedure time, or delayed bleeding rate between the groups.
CONCLUSION
Scissor knife-assisted ESD is as effective as conventional knife-assisted ESD for colorectal lesions with lower intraoperative perforation rate and a higher self-completion rate.

Comparison of Endoscopic Mucosal Resection versus Endoscopic Submucosal Dissection for Barrett's Neoplasia and Esophageal Adenocarcinoma: A Systematic Review and Meta-Analysis.
BACKGROUND AND AIMS
Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are both accepted resection strategies for Barrett's esophagus-related neoplasia and esophageal adenocarcinoma (EAC). However, a lack of consensus exists regarding which technique offers superior outcomes. This study aims to systematically review the evidence comparing EMR versus ESD in treating Barrett's neoplasia and EAC.
METHODS
We searched three databases (Embase, MEDLINE, Cochrane Central) until October 2023. We included studies comparing the efficacy of EMR and ESD for Barrett's neoplasia and EAC. Primary outcomes include en bloc, R0, and curative resection, complete remission of dysplasia (CRD), and local recurrence. Secondary outcomes encompass adverse events.
RESULTS
Our search identified 905 records. Eleven studies were included in the final analyses. Data showed significantly higher en bloc resection rates with ESD [odds ratio(OR)=27.36 (95% confidence intervals(CI):7.12-105.21), p<0.01, 6 studies]. R0 resection rates were significantly higher with ESD [OR=5.73 (95%CI:2.32-14.16), p<0.01, 7 studies]. Curative resection rates tended to be higher with ESD [OR=3.49 (95%CI:0.86-14.14), p=0.080, 4 studies]. There was no significant difference in CRD rates [OR=0.92 (95%CI:0.37-2.26),p=0.86, 3 studies]. Local recurrence rates tended to be lower with ESD [OR=0.35 (95%CI: 0.11-1.04), p=0.058, 10 studies]. As for adverse events, there was no significant difference in bleeding, perforation, and postoperative stricture rates.
CONCLUSIONS
This systematic review and meta-analysis demonstrates that ESD achieves higher en bloc, R0 and curative resection rates, with a tendency toward lower recurrence rates. These results suggest that ESD may be a more effective option for managing Barrett's neoplasia and EAC.

Meta-Analysis Review
INTRODUCTION
Appendicectomy remains the standard treatment for appendicitis. There is a lack of clarity on the timeframe in which surgery should be performed to avoid unfavourable outcomes.
AIM
To perform a systematic review and network meta-analysis to evaluate the impact the (1)time-of-day surgery is performed (2), time elapsed from symptom onset to hospital presentation (patient time) (3), time elapsed from hospital presentation to surgery (hospital time), and (4)time elapsed from symptom onset to surgery (total time) have on appendicectomy outcomes.
METHODS
A systematic review was performed as per PRISMA-NMA guidelines. The time-of-day which surgery was done was divided into day, evening and night. The other groups were divided into < 24 h, 24-48 h and > 48 h. The rate of complicated appendicitis, operative time, perforation, post-operative complications, surgical site infection (SSI), length of stay (LOS), readmission and mortality rates were analysed.
RESULTS
Sixteen studies were included with a total of 232,678 patients. The time of day at which surgery was performed had no impact on outcomes. The incidence of complicated appendicitis, post-operative complications and LOS were significantly better when the hospital time and total time were < 24 h. Readmission and mortality rates were significantly better when the hospital time was < 48 h. SSI, operative time, and the rate of perforation were comparable in all groups.
CONCLUSION
Appendicectomy within 24 h of hospital admission is associated with improved outcomes compared to patients having surgery 24-48 and > 48 h after admission. The time-of-day which surgery is performed does not impact outcomes.

BACKGROUND
Propeller perforator flaps (PPFs) have increased in popularity due to the freedom in design and ability to cover a variety of defects without sacrificing the major vessels. Present reports of PPFs for upper limb reconstruction have not provided guidance for hand reconstruction, specifically. This study aims to review the current literature and evaluate techniques for use of PPFs in hand reconstruction.
METHODS
A comprehensive literature review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for articles published from 1991 to 2021. The database search was queried for records using appropriate Medical Subject Headings (MeSH) terms. Studies reporting PPFs were limited to English language and excluded lower extremity or upper extremity reconstruction not specific to defects in the hand or digits. Study characteristics, patient demographics, indications, preoperative testing, flap characteristics, flap survival, and complication rates were collected.
RESULTS
Out of the initial 1,348 citations yielded, 71 underwent full-text review. Ultimately, 25 unique citations were included encompassing 12 retrospective reviews (48%), 3 prospective cohort studies (10%), and 10 case series (40%). In review, 525 patients underwent reconstruction with a total of 613 propeller flaps performed to repair defects of the hand, digits, or both with use of 18 unique flap types. Overall flap survival was 97.8%. Acute wounds accounted for 72.9% of performed reconstructions. The mean flap coverage was 14.7 cm. Complications occurred in 19.8% of cases, with venous congestion and partial flap necrosis occurring in 5.5 and 6.5% of cases, respectively, leading to a flap failure rate of 2.1%.
CONCLUSION
PPFs are a reliable option for hand or digital reconstruction, allowing surgeons to cover a variety of defects without sacrificing local vasculature. Despite nearly a 20% reported complication rate, nearly all flaps with venous congestion and partial flap necrosis included in these articles resolved without the need for secondary intervention, retaining an excellent overall flap survival.

Review
Appendicitis is one of the most common gastrointestinal conditions a person can develop. Throughout the years of assessing the different focuses of appendicitis, such as origin, symptoms, labs, diagnosis, treatment, and complications, there have been mere mentions of sex differences. One of the most known sex differences in appendicitis is the fact that males are significantly more likely to develop appendicitis compared to females. Another postulated difference is that males may be more likely to develop a perforated appendix. These differences significantly affect the various aspects of diagnosing and treating appendicitis and may even influence the outcome of appendicitis. Sex difference analysis of conditions has been widely researched over the last two decades, and sex can influence and impact conditions from initial presentation to the outcome of treatment. This paper evaluates the sex differences in appendicitis concerning incidence, risk factors, symptoms, diagnosis technique, treatment, and outcomes across ages. Following PRISMA guidelines, this systematic review reviewed PubMed, ScienceDirect, and ProQuest databases for articles pertaining to sex differences in appendicitis. The original article count was 21,121, which was narrowed down to 28 publications. It was found that, as previously described, males had a significantly higher rate of appendicitis, as well as were at significant risk of perforated appendicitis. No official risk factors were found to differ between the sexes, but males were more likely to complain of symptoms like right lower quadrant cramps/tenderness/pain and loss of appetite. Scores such as the pediatric appendicitis score (PAS) and Ohmann have been used to diagnose appendicitis, but the PAS was significantly more accurate for females, and the Ohmann resulted in significantly fewer negative appendectomies in females as well. Ultrasound and computed tomography (CT) are still the gold standards for diagnosis; however, while time to CT was significantly delayed in females, they were more likely to undergo extensive imaging, possibly to rule out other conditions. Males were more likely to undergo open appendectomies compared to females, who more frequently underwent laparoscopic appendectomy, yet females were more likely to experience complications. Further research should evaluate the influences that can predict postoperative outcomes following appendectomies between sexes and how to prevent/reduce their occurrence.

Endoscopic resection has traditionally involved electrosurgical cautery (hot snare) to resect premalignant polyps. Recent data have suggested superior safety of cold resection. We aimed to assess the safety of cold compared with traditional (hot) resection for non-ampullary duodenal polyps. We performed a systematic review ending in September 2022. The primary outcome of interest was the adverse event (AE) rate for cold compared with hot polyp resection. We reported odds ratios with 95% confidence intervals (CIs). Secondary outcomes included rates of polyp recurrence and post-polypectomy syndrome. We assessed publication bias with the classic fail-safe test and used forest plots to report pooled effect estimates. We assessed heterogeneity using I index. Our systematic review identified 1,215 unique citations. Eight of these met inclusion criteria, seven of which were published manuscripts and one of which was a recent meeting abstract. On random effect modeling, cold resection was associated with significantly lower odds of delayed bleeding compared with hot resection. The difference in the odds of perforation (odds ratio [OR] 0.31 [95% confidence interval [CI] 0.05-2.87], =0.2, I =0) and polyp recurrence (OR 0.75 [95% CI 0.15-3.73], =0.72, I =0) between hot and cold resection was not statistically significant. There were no cases of post-polypectomy syndrome reported with either hot or cold techniques. Cold resection is associated with lower odds of delayed bleeding compared with hot resection for duodenal tumors. There was a trend toward higher odds of perforation and recurrence following hot resection, but this trend was not statistically significant.

Fast-track recovery after surgery for perforated peptic ulcer safely shortens hospital stay: A systematic review and meta-analysis of six randomized controlled trials and 356 patients.
BACKGROUND
Postoperative management after surgery for perforated peptic ulcer is still burdened by old traditions. All available data for fast-track recovery in this setting are either very unspecific or underpowered. The aim of this study was to evaluate fast-track recovery in this diagnosis-specific context in a larger sample.
METHODS
Electronic data sources were searched. Eligible studies were randomized controlled trials (RCTs) comparing fast-track recovery and traditional management after surgery for perforated peptic ulcer in adults. A systematic review and meta-analysis was performed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines regulated the process. Quality and risk of bias assessments of individual RCTs were performed by means of the Let Evidence Guide Every New Decision criteria and the Cochrane risk-of-bias tool. Primary endpoints were length of hospital stay and risk of complications. Random or fixed effects modeling were applied as indicated. Outcomes were measured by mean difference and risk difference.
RESULTS
Six RCTs with a total cohort of 356 patients were included. Results of our meta-analysis showed significantly shortened length of hospital stay (mean difference -3.50 days [95% CI -4.51 to -2.49], p ≤ 0.00001), significantly less superficial and deep surgical-site infections (risk differences -0.12 [95% CI -0.20, -0.05], p = 0.002 and -0.03 [95% CI -0.09, 0.03], and p = 0.032, respectively), and significantly fewer pulmonary complications (risk difference -0.10 [95% CI -0.17, -0.03], p = 0.004) in the fast-track group.
CONCLUSION
This systematic review and meta-analysis shows that fast-track recovery after surgery for perforated peptic ulcer significantly shortened hospital stay in the studied cohort without increasing the risk of postoperative complications.

OBJECTIVE
This systematic review aimed to assess the different treatments of benign maxillo-mandibular radiolucent bone lesions over 4 cm to propose a management algorithm.
STUDY DESIGN
A literature search was conducted using MEDLINE/PubMed, Scopus, Google Scholar, Virtual Health Library databases, and gray literature. Randomized or non-randomized clinical trials and case series with 10 or more patients with a minimum follow up of 1 year, published in French or English until August 2023, were included. The risk of bias was assessed for all papers included.
RESULTS
Of 1433 records identified, 22 were included in this review, reporting data from 1364 lesions. Ameloblastoma was the most common lesion (51.22%) and mandible was the most common site (81.21%). Initial conservative treatment was prevalent (71.04%). Recurrence was higher after conservative (13.8%) than after radical treatments (6.5%). Multilocularity, cortical perforation, dental element preservation were linked to a higher recurrence risk.
CONCLUSION
This study has shown importance of understanding specific characteristics and recurrence risk in benign maxillomandibular osteolytic lesions. Multidisciplinary team approval, personalized approach based on lesion type and patient are crucial. The presence of at least one risk factor could lead to therapeutic decision. Despite limitations, the study informed lesion management and provided precise recommendations.

The Influence of Symptomatic Status on Post-endoscopic Retrograde Cholangiopancreatography (ERCP) Complications in Choledocholithiasis: A Systematic Review and Meta-Analysis.
Choledocholithiasis presents variably, with some patients remaining asymptomatic, complicating decisions regarding the timing and necessity of endoscopic retrograde cholangiopancreatography (ERCP). This study represents the first meta-analysis assessing the impact of symptomatic status on post-ERCP complications and provides critical data to optimize treatment strategies. A systematic review and meta-analysis were conducted by searching PubMed, Embase, and Google Scholar through February 2024, focusing on comparing ERCP outcomes between symptomatic and asymptomatic patients with choledocholithiasis. Seven studies were included from an initial pool of 1,200 articles screened. The analysis revealed that asymptomatic patients exhibited a significantly higher overall complication rate (17.4% vs. 6.6%), including a threefold increase in the risk of developing complications overall (OR: 3.02; 95% CI: 2.26-4.03) and specifically post-ERCP pancreatitis (OR: 3.62; 95% CI: 2.63-4.99). Perforation and procedural durations were also notably higher among asymptomatic individuals. Subgroup analyses highlighted prolonged cannulation times and the use of precut sphincterotomy as potential influential factors. These findings challenge the current practice that does not differentiate based on symptomatic status and suggest a need for more tailored approaches in managing asymptomatic individuals to minimize risks associated with ERCP.

Meta-Analysis
BACKGROUND
We reviewed the literature to examine if the thickness of the sinus membrane is a risk factor for perforation during lateral sinus lift surgery.
MATERIAL AND METHODS
We searched Embase, PubMed, and Web of Science databases till 4th December 2023 for studies examining the risk of perforation with different sinus membrane thicknesses. Studies reporting sinus membrane thickness in perforation and non-perforation cases were also included.
RESULTS
Eleven studies were eligible. All studies used cone beam computed tomography for measuring sinus membrane thickness. Meta-analysis showed that sinus membrane thickness was significantly lower in perforation cases as compared to non-perforation cases (MD: -0.91 95% CI: -1.48, -0.33 I2=94%). Four studies used 2mm as the cut-off to define thick and thin sinus membranes. Pooled analysis failed to demonstrate any significant difference in perforation rates (OR: 0.97 95% CI: 0.44, 2.17 I2=56%). Meta-analysis of studies using 1.5mm (OR: 0.66 95% CI: 0.29, 1.48 I2=72%) and 1mm cut-off (OR: 0.93 95% CI: 0.34, 2.56) also demonstrated similar non-significant results.
CONCLUSIONS
Our study shows that the sinus membrane is significantly thinner in cases with perforations as compared to those with no perforations. However, a meta-analysis based on different membrane thickness cut-offs failed to demonstrate a relationship between thinner sinus membranes and a higher risk of perforation. There is a need for further studies examining the role of sinus membrane thickness on perforation rates.
