Review
INTRODUCTION
The sitting position for pineal tumour removal remains controversial as regards the number of potential complications despite good surgical conditions.
METHOD
A systematic review of the literature was conducted in order to record the most frequent complications observed in this position, their incidence and prevention.
RESULTS
Venous air embolism, hypotension, pneumocephalus, macroglossia, quadriplegia and nerve injuries are the most frequent complications observed. Their incidence can be dramatically decreased with an accurate anesthesiological and neurosurgical management.
CONCLUSION
In training teams, the sitting position remains the gold standard for pineal tumour removal.

Meta-Analysis
BACKGROUND
Internal fixation with cephalomedullary nails has been widely used in the treatment of intertrochanteric femoral fractures (IFF). Yet, the difference in efficacy and safety between the commonly used integrated dual-screw cephalomedullary nail (InterTAN) and single-screw cephalomedullary nail remains inconclusive. Thus we performed the present systematic review and meta-analysis.
METHODS
Randomized controlled trials (RCTs) or observational studies comparing InterTAN with proximal femoral nail anti-rotation (PFNA), the Asian PFNA (PFNA-II), or the Gamma3 nail in treating IFF were searched on PubMed, EMBASE, Web of Science and Cochrane Library from inception to April 30, 2023. The differences in perioperative parameters and clinical and radiological outcomes were evaluated by mean difference (MD) with 95% confidence interval (95%CI). The risks of various complications and mortality were assessed by risk ratio (RR) with 95%CI.
RESULTS
Twenty-three studies comprising 3566 patients were included. Compared with single-screw cephalomedullary nails (PFNA/PFNA-II, Gamma3), InterTAN conferred significantly reduced risk of implant failures (RR = 0.37, 95%CI 0.26 to 0.51, P < 0.001), hip and thigh pain (RR = 0.70, 95%CI 0.55 to 0.90, P = 0.006) and all-cause revision/reoperation (RR = 0.38, 95%CI 0.26 to 0.57, P < 0.001). Moreover, patients treated with InterTAN had significantly higher 1-year Harris Hip Score (MD = 0.82, 95%CI 0.20-1.44, P = 0.010) and shorter time to union/healing (MD = - 0.66 days, 95%CI - 1.16 to - 0.16, P = 0.009). Femoral neck shortening, time to full bearing, and incidences of non-union, infection, deep venous thrombosis, and mortality were comparable between both groups.
CONCLUSIONS
The integrated dual-screw InterTAN construct has superior performance in reducing risks of complications and improving clinical and functional outcomes in the treatment of IFF. More well-designed, high-quality RCTs are warranted to confirm these findings.

Archives of Gynecology and Obstetrics Jun 2016Robotic hysterectomy is an alternative approach to the management of female genital tract pathology. (Review)
Review
OBJECTIVE
Robotic hysterectomy is an alternative approach to the management of female genital tract pathology.
METHODS
A systematic literature review was performed to evaluate the till now available literature evidence on robotic assisted hysterectomy in obese and morbidly obese patients.
RESULTS
In total, robotic assisted hysterectomy was performed on 2769 patients. The most frequent indication for robotic hysterectomy was endometrial carcinoma (1832 out of 2769 patients, 66.2 %). Hypertension, diabetes mellitus, obstructive sleep apnea, chronic obstructive pulmonary disease and venous thromboembolism were the most common comorbidities reported. The conversion rate to laparotomy was 92 out of 2226 patients (4.1 %). The most frequent intraoperative complications for robotic hysterectomy were gastrointestinal injury (17 out of 2769 patients, 0.6 %), haemorrhage (five out of 2769 patients, 0.2 %) and bladder injury (five out of 2769 patients, 0.2 %). Wound infections/dehiscence (66 out of 2769 patients, 2.4 %), fever (56 out of 2769 patients, 2 %), pulmonary complications (55 out of 2769 patients, 1.9 %), urogenital complications (36 out of 2769 patients, 1.3 %) and postoperative ileus (28 out of 2769 patients, 1 %) were the most common postoperative complications. Death was reported in three out of 2769 patients (0.1 %). The ICU admitted patients were eight of 2226 patients (0.4 %).
CONCLUSION
The robotic technique, especially in obese, can optimize the surgical approach and recovery of such patients with equally if not better outcomes compared to open and/or laparoscopic techniques.

Meta-Analysis Review
The effectiveness and safety of direct oral anticoagulants compared to conventional pharmacologic thromboprophylaxis in hip fracture patients: A systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
Direct oral anticoagulants (DOACs) are recommended as a possible pharmacologic venous thromboembolism (VTE) prophylaxis in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). However, current guidelines did not introduce recommendations for administration of DOACs as an option for pharmacologic VTE prophylaxis in patients undergoing hip fracture surgery (HFS). The purpose of this study is to compare the effectiveness and safety of DOACs administered for pharmacologic VTE prophylaxis in patients undergoing HFS to conventional pharmacologic VTE prophylaxis, as well as mortality between these thromboprophylaxis medications.
METHODS
We performed a systematic review of multiple electronic databases for randomized controlled trials (RCTs) including patients who were subjected to HFS and prescribed either DOACs as pharmacologic VTE prophylaxis or a conventional VTE prophylaxis drug. We conducted a meta-analysis comparing effectiveness, safety and mortality of these agents between the patient groups studied. Three endpoints were studied. The first one regarding the effectiveness of the agents included clinical manifestations of VTE. The second one regarding the safety of the agents included clinical presentation of bleeding. The latter endpoint studied was mortality of patient groups studied. We generated forest plots to depict the relative risk of the above clinical manifestations between the two studied patient groups and to investigate if there is statistical significance for each patient group to present any of these clinical manifestations. Additionally, we calculated the inconsistency (I) statistic and assessed the risk of bias of RCTs included in our meta-analysis by using the modified Cochrane collaboration tool.
RESULTS
We selected 2 RCTs in this review including 279 patients totally. Patients of control groups in both eligible studies were administered enoxaparin, which is a low molecular weight heparin (LMWH). The meta-analysis found no statistically significant difference between patients prescribed DOACs and patients prescribed LMWH for VTE (95% CI 0.19 to 1.13, RR=0.46, p=0.09), deep vein thrombosis (DVT) (95% CI 0.21 to 1.32, RR=0.53, p=0.17) and pulmonary embolism (PE) (95% CI 0.03 to 3.12, RR=0.33, p=0.33), major bleeding events (95% CI 0.57 to 1.78, RR=1.01, p=0.97), minor bleeding events (95% CI 0.72 to 1.64, RR=1.09, p=0.69), all bleeding events (95% CI 0.79 to 1.38, RR=1.05, p=0.74) and mortality (95% CI 0.01 to 8.0, RR=0.33, p=0.5). The major risk of bias of the selected RCTs was the fact that either the researchers or the patients could have knowledge whether the latter were administered DOACs or LMWHs.
DISCUSSION
DOACs are not inferior compared to LMWHs regarding their effectiveness, safety and mortality in patients subjected to HFS. Further studies with larger patient samples should be conducted in the future, so that safer results and conclusions could be reached.

BACKGROUND
Uterine transplantation (UTx) is acknowledged to be on the second (2A) of five steps of development in accordance with the staging system for the evaluation of surgical innovations. Accordingly, we aimed to systematically review the available evidence of the surgical techniques and outcomes of UTx in terms of graft survival.
METHODS
A comprehensive search was conducted across PubMed Medline, Cochrane-EBMR, Scopus, Web of Science, and CENTRAL through November 2020.
RESULTS
Forty studies, reporting 64 recipients and 64 donors, satisfied inclusion criteria. The surgical time and the estimated blood loss were 515 minutes and 679 mL for graft procurement via laparotomy, 210 minutes and 100 mL for laparoscopic-assisted graft harvest, and 660 minutes and 173 mL for robotic-assisted procedures, respectively. Urinary tract infections ( = 8) and injury to the urinary system ( = 6) were the most common donor complications. Using the donor's internal iliac system, two arterial anastomoses were performed in all cases. Venous outflow was accomplished through the uterine veins (UVs) in 13 cases, a combination of the UVs and the ovarian/uteroovarian veins (OVs/UOVs) in 36 cases, and solely through the OVs/UOVs in 13 cases. Ischemia time was 161 and 258 minutes when using living donors (LD) and deceased donors (DD), respectively. Forty-eight uteri were successfully transplanted or fulfilled the purpose of transplantation, 41 from LDs and 7 from DDs. Twenty-five and four live childbirths from LDs and DDs have been reported, respectively.
CONCLUSION
UTx is still experimental. Further series are required to recommend specific surgical techniques that best yield a successful transplant and reduce complications for donors and recipients.

BACKGROUND
Severe acute burn injuries represent a challenge to the reconstructive surgeon. Free flap reconstruction might be required in cases of significant critical structure exposure and soft tissue deficits, when local options are unavailable. This study aimed to determine the free flap complication rate in acute burn patients.
METHODS
A systematic review and meta-analysis were conducted and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines and registered on the International Prospective Register of Systematic Reviews database (CRD42023404478). The following databases were accessed: Embase, PubMed, Web of Science, and Cochrane Library. The primary outcome was the free flap failure rate.
RESULTS
The study identified 31 articles for inclusion. A total of 427 patients (83.3% men, 16.7% women) accounting for 454 free flaps were included. The mean patient age was 36.21 [95% confidence interval (CI), 31.25-41.16]. Total free flap loss rate was 9.91% [95% CI, 7.48%-13.02%], and partial flap loss was 4.76% [95% CI, 2.66%-8.39%]. The rate of venous thrombosis was 6.41% [95% CI, 3.90%-10.36%] and arterial thrombosis was 5.08% [95% CI, 3.09%-8.26%]. Acute return to the operating room occurred in 20.63% [16.33%-25.71%] of cases. Stratified by body region, free flaps in the lower extremity had a failure rate of 8.33% [95% CI, 4.39%-15.24%], whereas in the upper extremity, the failure rate was 6.74% [95% CI, 3.95%-11.25%].
CONCLUSION
This study highlights the high risk of free flap complications and failure in acute burn patients.

Meta-Analysis Review
BACKGROUND
Endothermal treatment of the great saphenous vein (GSV) has become the first-line treatment for superficial venous reflux. Nonthermal ablation has potential benefits for acceptability by patients and decreased risk of nerve injury. We performed a systematic review and meta-analysis to evaluate the efficacy of mechanochemical endovenous ablation (MOCA) and cyanoacrylate vein ablation (CAVA) for GSV incompetence.
METHODS
MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane databases were searched for papers published between January 1966 and December 2016. Eligible articles were prospective studies that included patients treated for GSV incompetence and described the primary outcome. Exclusion criteria were full text not available, case reports, retrospective studies, small series (n < 10), reviews, abstracts, animal studies, studies of small saphenous vein incompetence, and recurrent GSV incompetence. Primary outcome was anatomic success. Secondary outcomes were initial technical success, Venous Clinical Severity Score, Aberdeen Varicose Vein Questionnaire score, and complications.
RESULTS
Fifteen articles met the inclusion criteria. Pooled anatomic success for MOCA and CAVA was 94.7% and 94.8% at 6 months and 94.1% and 89.0% at 1 year, respectively. Venous Clinical Severity Score and Aberdeen Varicose Vein Questionnaire score significantly improved after treatment with MOCA and CAVA.
CONCLUSIONS
These results are promising for these novel techniques that could serve as alternatives for thermal ablation techniques. However, to determine their exact role in clinical practice, high-quality randomized controlled trials comparing these novel modalities with well-established techniques are required.

INTRODUCTION
Post-thrombotic syndrome (PTS) is the most common chronic complication of deep vein thrombosis. Recent studies suggested that iliac stenting in chronic obstructive venous disease is safe and effective. However, systematic reviews focusing on mid-term efficacy of iliac stenting in post-thrombotic syndrome are lacking. This systematic review aimed to analyze mid-term stent patency rates and clinical outcomes of iliac stenting in post-thrombotic syndrome.
EVIDENCE ACQUISITION
Two databases were searched: Pubmed/Medline and Scopus. Articles published between January 2000 and July 2020 were selected and titles and abstracts were independently reviewed. Eighteen articles were included for the qualitative analysis. From this initial set of articles, fourteen articles were included for the quantitative analysis.
EVIDENCE SYNTHESIS
Overall, 1008 patients were included in this study. The pooled technical success rate was 96%. The pooled primary and secondary patency rates were 98.2% and 100% at 30 days, 78.1% and 94.5% at 12 months and 66.3% and 89.4% at 36 months, respectively. The rates of ulcer healing, pain and edema relief were 78.1%, 53.4% and 48.8%, respectively. The pooled rate of complications including intraoperative venous injury, back pain and stent fracture were 28%, 57.1%, and 5.9%, respectively.
CONCLUSIONS
Iliac venous stenting in PTS presents durable mid-term patency rates, as well as significant symptomatic improvement. Therefore, endovascular treatment should be considered in symptomatic patients with PTS.

Review
BACKGROUND
Fingertip reconstruction using reverse-flow homodigital island flaps has been very popular over the years. However, the outcomes of reconstruction have not been clearly understood. In these circumstances, a systematic review of available literature is warranted.
OBJECTIVE
To assess the outcomes and complications of fingertip reconstruction using reverse-flow homodigital island flaps. To justify the usage of reverse-flow homodigital island flaps for fingertip reconstruction.
SEARCH METHODS
A PubMed [MEDLINE] electronic database was searched (1985 to 15 April 2015).
SELECTION/ELIGIBILITY CRITERIA
Retrospective case series that met the following criteria were included: (1) Study reported primary data; (2) Study included at least five cases of fingertip defects treated using reverse-flow homodigital island flaps; (3) Study reported outcomes and complications of fingertip reconstruction, either primary or delayed, using reverse-flow homodigital island flaps; (4) The study presented at least one of the following functional outcomes: Static two-point discrimination, return-to-work time, range of motion of distal interphalangeal joints; (5) The study presented at least one complication.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed search results, and two other review authors analyzed the data and resolved disagreements. The following endpoints were analyzed: survival rate of the flap, sensibility, and functional outcomes and complications.
MAIN RESULT
Eight studies were included in this review. The included studies were published between 1995 and 2014, and a total of 207 patients with 230 fingertip defects were reported. The overall survival rate of the flap was 98 % (including partial survival). The mean static two-point discrimination (2PD) was 7.2 mm. The average range of motion of the DIP joint was 63°. The average return-to-work time was 7 weeks after injury. On average, 2 % of the patient had complete flap necrosis, 5 % had partial flap necrosis, 4 % developed venous congestion, 4 % developed flexion contracture, and 12 % experienced mild-to-moderate cold intolerance.
AUTHORS' CONCLUSIONS
Survival of reconstructed fingertips (98 %) is better with reverse-flow homodigital island flaps than fingertip replantation (86 %). The sensibility outcome using sensate flaps (mean s2PD = 7.2 mm) is similar to the sensibility outcome following replantation (mean s2PD = 7 mm). The common complications include cold intolerance, venous congestion, and flexion contracture. Therefore, reverse-flow homodigital island flaps may not be the ideal choice but are a very reliable alternative for fingertip reconstruction.

Meta-Analysis Review
BACKGROUND
Neonatal parenteral nutrition may be delivered via peripheral cannulas or central venous catheters (umbilical or percutaneous). As the result of complications associated with umbilical catheters, many neonatal units prefer to use percutaneous catheters after initial stabilisation. Although they can be difficult to place, these catheters may be more stable than peripheral cannulae and require less frequent replacement. These delivery methods may be associated with different risks of adverse events, including acquired invasive infection and extravasation injury.
OBJECTIVES
To determine the effects of infusion of parenteral nutrition via percutaneous central venous catheters versus peripheral cannulae on nutrient input, growth and development and complications among hospitalised neonates receiving parenteral nutrition in terms of adverse consequences such as bacteraemia or invasive fungal infection, cardiac tamponade or other extravasation injuries.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 5), MEDLINE (1966 to June 2015) and EMBASE (1980 to June 2015), as well as conference proceedings and previous reviews.
SELECTION CRITERIA
Randomised controlled trials that compared delivery of intravenous fluids (primarily parenteral nutrition) via percutaneous central venous catheters versus peripheral cannulae in hospitalised neonates.
DATA COLLECTION AND ANALYSIS
We extracted data using standard methods of the Cochrane Neonatal Group, with separate evaluation of trial quality and data extraction by two review authors.
MAIN RESULTS
We found six trials recruiting a total of 549 infants. One trial showed that use of a percutaneous central venous catheter was associated with a smaller deficit between prescribed and actual nutrient intake during the trial period (mean difference (MD) -7.1%, 95% confidence interval (CI) -11.02 to -3.2). Infants in the percutaneous central venous catheter group needed significantly fewer catheters/cannulae (MD -4.3, 95% CI -5.24, -3.43). Meta-analysis of data from all trials revealed no evidence of an effect on the incidence of invasive infection (typical risk ratio (RR) 0.95, 95% CI 0.72 to 1.25; typical risk difference (RD) -0.01, 95% CI -0.08 to 0.06).
AUTHORS' CONCLUSIONS
Data from one small trial suggest that use of percutaneous central venous catheters to deliver parenteral nutrition increases nutrient input. The significance of this in relation to long-term growth and developmental outcomes is unclear. Three trials suggest that use of percutaneous central venous catheters decreases the number of catheters/cannulae needed to deliver nutrition. No evidence suggests that percutaneous central venous catheter use increases risks of adverse events, particularly invasive infection, although none of the included trials was large enough to rule out an effect on uncommon severe adverse events such as pericardial effusion.
