Comparison of Modified Above-Knee and Conventional Surgery with the Stripping of the Great Saphenous Vein of Varicose Veins of the Lower Extremities: A Retrospective Study

Objective. To compare the clinical effects of modified above-knee and conventional surgery with the stripping of the great saphenous vein of varicose veins of the lower extremities. Methods. Clinical data of patients with a varicose vein of the lower extremity from May 2016 to May 2018 were collected. A retrospective study was conducted on the patients receiving modified above-knee and conventional surgery with the great saphenous vein stripping. The baseline characteristics and long-term follow-up data were compared between the groups. Results. There were no significant differences in baseline characteristics between the two groups ( P > 0.05 ). The surgeries were successfully performed by the same group of surgeons under local anesthesia and neuraxial anesthesia. The hospital stay, operation time, intraoperative blood loss, total length, and number of incisions in the above-knee group were comparable to those in the conventional surgery group ( P > 0.05 ). The incidence of saphenous nerve injury and subcutaneous hematoma in the above-knee group was lower than that in the conventional surgery group ( P < 0.05 ). There were no significant differences in recurrent varicose vein incidences ( P > 0.05 ). After surgery, the venous clinical severity score (VCSS) and chronic venous insufficiency questionnaire (CIVIQ-14) scores of both groups were higher than those before operation ( P < 0.05 ). There was no significant difference in VCSS score or CIVIQ-14 scores between the two groups postoperation ( P > 0.05 ). At 24 months after surgery, the above-knee group (71.8%) and conventional surgery group (73.2%) resulted in changes of at least two CEAP-C clinical classes lower than baseline, respectively. Conclusion. The modified above-knee technique can ensure clinical outcomes, reduce intraoperative blood loss and complication incidences, and shorten the operative time. This gives evidence that the modified above-knee technique is worthy of clinical application.

Characteristics of postoperative pain after mini invasive and conventional mitral surgery in Hanoi Heart Hospital

Introduction: Mini invasive mitral valve surgery had some advantages over conventional surgery in recovery and cosmestic results. Postoperative pain was an interested factor for comparing these two methods, with reported results remained unclear. We realized this study for evaluate the characteristics of postoperative pain between mini invasive and conventional mitral surgery in Hanoi Heart Hospital. Methods: A cross sectional study on patient underwent mitral valve replacement with mini invasive and conventional sternotomy approach. Results: There were 66 patients in the study, divided into 2 group: 43 patient underwent conventional surgery and 23 patient underwent mini invasive surgery. Mean age was 50,7 ± 9,3, female was 78,8% and mean BMI was 20,9 ± 2,7. Erector spinae plane (ESP) block was performed on 16 patients (24,2%) of conventional surgery group. The VAS score at 3 days, 7 days , and 1 month after surgery was 7,7 ± 1,2; 5,2 ± 1,5; 0,9 ± 1,1 in sternotomy group and 6,6 ± 1,6; 3,8 ± 1,5; 1,7 ± 0,9 in mini invasive group, respectively. In patients with ESP block, mean dose of morphine administered in first two days was 0 and 2,3 ± 5,0 mg/kg comparing to the dose of 19,7 ± 5,5 và 17,7 ± 7,1 in sternotomy patients without ESP block. Conclusions: Postoperative pain reduction may not be an advantage of mini invasive mitral surrgery comparing to conventional surrgery, but the time for pain suffering in this group was shorter. ESP was an efficient method for early pain reduction after conventional surgery.

An overview on the art of piezosurgery in the maxillofacial practice

Introduction: Piezosurgery is an emerging boom in the field of maxillofacial surgery for precise, safe and effective osteotomies sparing the adjacent vital structures compared to conventional surgery. Corpus: It works on the principle of piezoelectric effect in which crystals in the piezoelectric substances get deformed on the application of an electric field. Various studies gave the evidence of improved wound healing and bone formation compared to conventional approaches. The soft tissue sparing capability with improved patient comfort and decreased blood loss gave the utmost importance for this surgical technique in the present as well as future world of surgery. Conclusion: Piezosurgery has emerging as a promising surgical modality with a wide range of clinical applications throughout the whole field of surgery.

Intraoperative Near-Infrared Fluorescence Guided Surgery Using Indocyanine Green (ICG) for the Resection of Sarcomas May Reduce the Positive Margin Rate: An Extended Case Series

Background: Sarcomas are rare, aggressive cancers which can occur in any region of the body. Surgery is usually the cornerstone of curative treatment, with negative surgical margins associated with decreased local recurrence and improved overall survival. Indocyanine green (ICG) is a fluorescent dye which accumulates in sarcoma tissue and can be imaged intraoperatively using handheld near-infrared (NIR) cameras, theoretically helping guide the surgeon’s resection margins. Methods: Patients operated on between 20 February 2019 and 20 October 2021 for intermediate to high grade sarcomas at our centres received either conventional surgery, or were administered ICG pre-operatively followed by intra-operative NIR fluorescence guidance during the procedure. Differences between the unexpected positive margin rates were compared. Results: 115 suitable patients were identified, of which 39 received ICG + NIR fluorescence guided surgery, and 76 received conventional surgery. Of the patients given ICG, 37/39 tumours fluoresced, and surgeons felt the procedure was guided by the intra-operative images in 11 cases. Patients receiving ICG had a lower unexpected positive margin rate (5.1% vs. 25.0%, p = 0.01). Conclusions: The use of NIR fluorescence cameras in combination with ICG may reduce the unexpected positive margin rate for high grade sarcomas. A prospective, multi-centre randomised control trial is now needed to validate these results.

Clinical parameters in soft tissue adjunctive periodontal procedures for orthodontic patients: surgical laser vs scalpel -: A systematic review

ABSTRACT Objectives To systematically review existing literature regarding clinical parameters comparing surgical laser and conventional surgery with scalpel for soft tissue adjunctive periodontal procedures in orthodontic patients. Methods and Materials MEDLINE, Scopus, Web of Science, The Cochrane Library, LILACS, Bibliografia Brasileira de Odontologia (Brazilian Dental Literature - BBO), Embase, Open Grey, Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Coordination for the Improvement of Higher Education Personnel - CAPES), and Google Scholar were searched up to December 2020 without language restriction. Clinical trials comparing clinical parameters from surgical laser and conventional surgery with scalpel for soft tissue adjunctive periodontal procedures in orthodontic patients were selected. Risk of bias (RoB) assessments were performed using the Cochrane RoB2 tool. Narrative syntheses were performed, and the certainty of evidence was determined using the GRADE tool. Results Five randomized clinical trials were included. One study was rated as low RoB, whereas others presented some concerns or high RoB. The studies were highly heterogeneous in relation to the procedure performed, laser protocol, outcomes evaluated, and follow-up periods. In general, regardless of the procedure and laser protocol used, the studies did not show significant differences between laser and scalpel for the outcomes of probing pocket depth, clinical crown length, gingival index, and relapse rate. Pain and bleeding were significantly lower with the use of laser compared with the scalpel. The certainty of evidence ranged from moderate to very low. Conclusions The existing literature on the subject is scarce and very heterogeneous and has methodological limitations. Based on the available evidence, it is not possible to draw definitive conclusions about the beneficial effect of laser use in orthodontic patients.

Effectiveness of the Endoscopic Prelacrimal Recess Approach for Maxillary Sinus Inverted Papilloma Removal: A Systematic Review and Meta-Analysis

Background Conventional minimally invasive surgery has a high recurrence rate, and nasal morbidity can occur if the scope of surgery is expanded to complete removal of maxillary sinus inverted papilloma. Objective To analyze the efficacy of the endoscopic prelacrimal recess approach (EPLRA) for maxillary sinus inverted papilloma removal. Methods Eighteen studies were included in this meta-analysis. Articles comparing the prelacrimal recess approach with conventional surgery (endoscopic surgery or the Caldwell–Luc operation) for inverted papilloma removal were included. Outcomes of interest included recurrence and postoperative morbidities. The methodological quality was assessed using the Newcastle–Ottawa scale. Results The recurrence rates of inverted papilloma, postoperative facial or gingival numbness, and alar collapse were 3.13% (95% confidence interval [CI]: 1.32, 7.27), 9.02% (95% CI: 3.70, 20.39), and 3.39% (95% CI: 1.28, 8.68), respectively. The recurrence rate of inverted papilloma was significantly lower after the EPLRA than after conventional surgery (odds ratio [OR] = 0.2290; 95% CI: 0.0808, 0.6489). However, there were no significant differences between the procedures in the rates of facial or gingival numbness (OR = 0.4567; 95% CI: 0.1497, 1.3933), epistaxis (OR = 0.3150; 95% CI: 0.0471, 2.1044), or periorbital swelling (OR = 1.2405; 95% CI: 0.1205, 12.7731). Conclusions The EPLRA can preserve the lacrimal system and is useful for maxillary sinus inverted papilloma removal due to a lower recurrence rate compared with conventional surgeries.
