New 'ZISIS' (Zigzag Incision-Suction-Irrigation System) Technique for Endoscopic-Assisted Forehead Tumour Excision.

ABSTRACT: Background:Endoscopic-assisted excision of forehead tumours like osteomas and lipomas is well established, but the conventional techniques suffer from many limitations like inadequate access, fogging of the endoscope and unclear vision due to collection of blood and debris. Method:Three simple modifications of the conventional endoscopic forehead technique for benign tumour excisions are described by the acronym 'ZISIS'. ZI Zigzag scalp incision increases the surface area of the opening permitting easy insertion of multiple instruments along with the endoscope.S Suction tubing made from a disposable suction catheter tube is taped along the endoscope sheath for continuous suctioning and good vision.IS Irrigation system of warm saline made with an infant feeding tube is also taped along the endoscope just opening in the front of the suction tube. Results:A total of 12 consecutive patients underwent endoscopic excision of forehead benign tumours in 2 years. This included 2 lipomas and 10 osteomas cases. All patients achieved excellent hidden scars in the scalp. All patients rated their results as excellent with respect to the hidden scar and aesthetic result. No early or late complications were reported with follow-up ranging from 6 months to 2 years. Conclusion:A new simple modification called 'ZISIS' endoscopic forehead excision technique is described for benign forehead tumours excision making it easier, efficient and ergonomic. Level of Evidence IV:Evidence obtained from multiple time series with or without the intervention, such as case studies.

Project description:Background A novel endoscopic-assisted technique (NET) was created by our team for nipple-sparing mastectomy (NSM) and latissimus dorsi muscle flap (LDMF) reconstruction that enables the procedure to be conducted through a single axillary incision. The authors hypothesized that the NET has the advantages of the traditional ET (TET) and a reduced operation time. The purpose of this study is to compare the advantages and disadvantages of NET, TET and open surgery. Methods A retrospective cohort study was performed on patients who underwent LDMF reconstruction after NSM using open surgery, the TET, or the NET between January 2013 and June 2021. The following outcomes were compared: the operation time, size of the LDMF, the complication rate, hospital length of stay, hospital costs, aesthetic results (the BREAST-Q questionnaire), and quality of life (QoL). The BREAST-Q questionnaire and QoL were underwent preoperatively and 1, 3, and 12 months postoperatively. Results A total of 17 ETs (comprising 10 NETs and 7 TETs) and 28 open surgery procedures were identified and analyzed, the baseline characteristics were comparable in terms of age, body mass index (BMI), tumor location, cup size, and disease stage of the three groups. The mean operation time of the NET group (395.8±176.0 min) in the exploration stage was shorter than that of the TET group (531.6±69.6 min) and equivalent to that of the open surgery group (400.9±67.3 min). The overall postoperative complication rates of the ET and open surgery groups were 35.3% and 60.7%, respectively (P=0.09). The aesthetic results in relation to patients’ satisfaction with their breasts (P=0.001) and backs (P=0.001) were better in the ET group than the open surgery group beginning at 1 month postoperatively. The ET group had better psychosocial well-being beginning at 1 month postoperatively (P=0.002) and sexual well-being beginning at 3 months postoperatively (P<0.001) than the open surgery group. Conclusions LDMF reconstruction after NSM using the ET is associated with lower complication rates, good aesthetic results, and a better QoL than open surgery procedures. The NET is a promising approach, a more convenient procedure, and has a shorter surgery time than TET, however, this conclusion needs to be further validated by randomized clinical trial (RCT) research with a larger sample size.

Project description:BACKGROUND:The primary management of pyogenic spondylodiscitis is conservative. Once the causative organism has been identified, by blood culture or biopsy, administration of appropriate intravenous antibiotics is started. Occasionally patients do not respond to antibiotics and surgical irrigation and debridement is needed. The treatment of these cases is challenging and controversial. Furthermore, many affected patients have significant comorbidities often precluding more extensive surgical intervention. The aim of this study is to describe early results of a novel, minimally invasive percutaneous technique for disc irrigation and debridement in pyogenic spondylodiscitis. MATERIALS AND METHODS:A series of 10 consecutive patients diagnosed with pyogenic spondylodiscitis received percutaneous disc irrigation and debridement. The procedure was performed by inserting two Jamshidi needles percutaneously into the disc space. Indications for surgery were poor response to antibiotic therapy (8 patients) and the need for more extensive biopsy (2 patients). Pre- and postoperative white blood cell count (WBC), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), Oswestry disability index (ODI), and visual analogue score (VAS) for back pain were collected. Minimum follow-up was 18 months, with regular interval assessments. RESULTS:There were 7 males and 3 females with a mean age of 67 years. The mean WBC before surgery was 14.63 × 109/L (10.9-26.4) and dropped to 7.48 × 109/L (5.6-9.8) after surgery. The mean preoperative CRP was 188 mg/L (111-250) and decreased to 13.83 mg/L (5-21) after surgery. Similar improvements were seen with ESR. All patients reported significant improvements in ODI and VAS scores after surgery. The average hospital stay after surgery was 8.17 days. All patients had resolution of the infection, and there were no complications associated with the procedure. CONCLUSIONS:Our study confirms the feasibility and safety of our percutaneous technique for irrigation and debridement of pyogenic spondylodiscitis. Percutaneous irrigation and suction offers a truly minimally invasive option for managing recalcitrant spondylodiscitis or for diagnostic purposes. The approach used is very similar to discography and can be easily adapted to different hospital settings. LEVEL OF EVIDENCE:Level III.
