Abstract Purpose The study aimed to evaluate the feasibility and safety of a new trans-anal rectoscopic-assisted minimally invasive surgery (ARAMIS) platform to treat rectal lesions. Methods ARAMIS was first compared with two transanal minimally invasive surgery platforms (SILS Port and GelPOINT Path) on human cadavers. Surgeons with different experience performed running sutures at different distances, at four quadrants, using the three platforms and gave a score to visibility, safety, and maneuverability. ARAMIS was then utilized on patients affected with rectal neoplasia who met the inclusion criteria. Patients and tumor characteristic and results were prospectively collected. The follow-up examinations included proctoscopy at 3, 6, and 12 months. Results According to surgeons’ scores, ARAMIS improves visibility and safety with respect to other platforms for distances beyond 10 cm. The procedure, which lasted an average of 59 min, was successfully carried out in 14 patients. No intraoperative or postoperative complications were reported. The mean tumor size was 3 cm; they were located a mean of 11 cm from the anal verge. Complete removal of the lesion was possible in 13/14 patients. There was one case of adenoma recurrence at follow-up. Conclusion Study results showed that ARAMIS, which is equipped with an adjustable rectoscope, can be considered a safe, effective platform for transanal surgery. The rectoscope protects the rectum during the procedure, a particularly important consideration when proximal rectal lesions are being treated. Further clinical studies are warranted to confirm these encouraging results.

Background: The aim of this study was to evaluate the feasibility, safety, perioperative morbidity, and short-term outcomes of the transanal minimally invasive surgery (TAMIS) technique. Methods: This is a descriptive review of prospectively collected data from 32 consecutive patients who underwent TAMIS procedures in our colorectal unit over a 40-month period. GelPOINT Path port was used in all cases. Demographic data, indications, tumor characteristics, morbidity, and follow-up data were collected. Primary endpoints included feasibility, safety, perioperative morbidity, and resection quality. Results: Fifteen adenomas, 12 carcinomas, 1 gastrointestinal stromal tumor, and 1 neuroendocrine tumor were locally excised. Additionally, 3 pelvic abscesses were drained transanally using the TAMIS port. Mean distance from the anal verge was 5.6 ± 1.5 cm. Early postoperative complications occurred in 22%, with only one case of major complication (3.1%) requiring reoperation, and no postoperative mortality. Four carcinomas were understaged (33.3%) and 1 adenoma overstaged (6.7%) preoperatively. Three carcinomas were not suspected preoperatively (25%). Microscopic positive lateral margin was found in one case, and no affected deep margin was found. Fragmentation rate was 6.9%, 2 cases, both lesions over 20 cm2. In cases of fit patients with high-risk carcinomas, 2 underwent immediate salvage surgery and another 2 refused and were treated with adjuvant radiotherapy. With a median follow-up of 26 months, the overall recurrence rate was 10.3%, 1 adenoma and 2 carcinomas. Conclusion: TAMIS seems to be a safe and reproducible procedure for local excision of well-selected rectal lesions with low morbidity and good functional outcomes.

Abstract Background Simulation-based practice has become increasingly important in minimally invasive surgery (MIS) training. Nevertheless, personnel resources for demonstration and mentoring simulation-based practice are limited. Video tutorials could be a useful tool to overcome this dilemma. However, the effect of video tutorials on MIS training and improvement of MIS skills is unclear. Methods A prospective randomised trial (n = 24 MIS novices) was conducted. A video-trainer with three different tasks (#1 – 3) was used for standardised goal-directed MIS training. The subjects were randomised to two groups with standard instructional videos (group A, n = 12) versus comprehensive video tutorials for each training task watched at specific times of repetition (group B, n = 12). Performance was analysed using the MISTELS score. At the beginning and following the curriculum, an MIS cholecystectomy (CHE) was performed on a porcine organ model and analysed using the GOALS score. After 18 weeks, participants performed 10 repetitions of tasks #1 – 3 for follow-up analysis. Results More participants completed tasks #1 and #2 in group B (83.3 and 75%) than in group A (66.7 and 50%, ns). For task #2, there was a significant improvement in precision in group B (p < 0.001). For the entire cohort, the GOALS-Scores were 12.9 before and 18.9 after the curriculum (p < 0.001), with no significant difference between groups. Upon follow-up, 84.2% (task#1), 26.3% (task#2) and 100% (task#3) of MIS novices were able to reach the defined goals (A vs. B ns). There was a trend for a better MISTELS score in group B upon follow-up. Conclusions Standardised comprehensive video tutorials watched frequently throughout practice can significantly improve precision in MIC training. This aspect should be incorporated in MIS training.

Abstract Background: The initial computed tomography (CT) blend sign has been used as an imaging marker to predict haematoma expansion and poor outcomes in patients with a small volume intracerebral haemorrhage (ICH). However, the relationship between the blend sign and outcomes remains elusive. The present study aimed to retrospectively measure the impact of initial CT blend signs on short-term outcomes in patients with hypertensive ICH who underwent stereotactic minimally invasive surgery (sMIS). Methods: We enrolled 242 patients with spontaneous ICH. Based on the initial CT features, the patients were assigned to a blend sign group (91 patients) or a nonblend sign (control) group (151 patients). The NIHSS, GCS and mRS were used to measure the effects of sMIS. The rates of severe pulmonary infection and cardiac complications were also compared between the two groups. Results: No significant differences in NIHSS and GCS scores were observed between the two groups. The proportion of patients with good outcomes during follow-up was not different between the two groups. The rate of rehaemorrhaging increased in the blend sign group. No significant differences in severe pulmonary infections and cardiac complications were noted between the two groups. Conclusions: The initial CT blend sign was not associated with poor outcomes in patients with hypertensive ICH who underwent sMIS. ICH patients with CT blend signs should undergo sMIS if they are suitable candidates for surgery.

Object Adult degenerative scoliosis can be a cause of intractable pain, decreased mobility, and reduced quality of life. Surgical correction of this problem frequently leads to substantial clinical improvement, but advanced age, medical comorbidities, osteoporosis, and the rigidity of the spine result in high surgical complication rates. Minimally invasive surgery is being applied to this patient population in an effort to reduce the high complication rates associated with adult deformity surgery. Methods A retrospective study of 23 patients was undertaken to assess the clinical and radiographic results with minimally invasive surgery for adult thoracolumbar deformity surgery. All patients underwent a lateral interbody fusion followed by posterior percutaneous screw fixation and possible minimally invasive surgical transforaminal lumbar interbody fusion if fusion near the lumbosacral junction was necessary. A mean of 3.7 intersegmental levels were treated (range 2–7 levels). The mean follow-up was 13.4 months. Results The mean preoperative Cobb angle was 31.4°, and it was corrected to 11.5° at follow-up. The mean blood loss was 477 ml, and the operative time was 401 minutes. The mean visual analog scale score improvement for axial pain was 3.96. Clear evidence of fusion was seen on radiographs at 84 of 86 treated levels, with no interbody pseudarthroses. Complications included 2 returns to the operating room, one for CSF leakage and the other for hardware pullout. There were no wound infections, pneumonia, deep venous thrombosis, or new neurological deficits. However, of all patients, 30.4% experienced new thigh numbness, dysesthesias, pain, or weakness, and in one patient these new symptoms were persistent. Conclusions The minimally invasive surgical treatment of adult deformities is a promising method for reducing surgical morbidity. Numerous challenges exist, as the surgical technique does not yet allow for all correction maneuvers used in open surgery. However, as the techniques are advanced, the applicability of minimally invasive surgery for this population will likely be expanded and will afford the opportunity for reduced complications.

However, the relationship between the blend sign and the outcome of patients remains elusive. The present study aimed to retrospectively observe the impact of initial CT blend signs on the short-term outcome of patients with hypertensive ICH underwent a stereotatic minimally invasive surgery (sMIS). Methods: Two hundreds and forty-two patients with spontaneous ICH were enrolled. Based on the initial CT features, the patients were assigned to a blend sign group (including 91 patients) or a non-blend sign group (control group, including 151 patients). The NIHSS, GCS and the mRS were used to observe the efficacy of the sMIS. The rates of severe pulmonary infection, cardiac complications were also compared between the two groups. Results: No significant differences in NIHSS and GCS in one week or two weeks after surgery were observed between the two groups. The proportion of patients with good outcome during follow-up did not show any difference between the two groups. However, both the two groups displayed good functional outcome over admission. The rate of rehaemorrhage increased in the blend sign group. No significant differences in severe pulmonary infections and cardiac complications were noted between the two groups. Conclusions：The initial CT blend sign are not associated with poor outcome of patients with hypertensive ICH underwent sMIS. ICH patients with CT blend sign should be also treated by performing sMIS if they are candidates for surgery.

AbstractThe dignity of adrenal masses in children varies from benign lesions like adenoma and ganglioneuroma to malignant tumors like adrenocortical carcinoma and neuroblastoma. Any surgical approach, especially minimally invasive surgery (MIS), requires careful risk stratification based on oncological and technical criteria. Herein, we present four patients who underwent MIS for adrenal masses. Laboratory testing differentiated between simple cysts and adenoma, but could not identify a child with adrenocortical tumor preoperatively. Analysis of image-defined risk factors excluded vascular encasement in all cases. All patients underwent laparoscopic adrenalectomy without complications. Histopathology revealed simple cyst, ganglioneuroblastoma, adenoma, and potentially malignant adrenocortical tumor in one patient/case each. All specimen showed clear margins and no recurrence was noted at a mean follow-up of 18 months.

Abstract BACKGROUND: Flexion-distraction injuries (FDI) represent 5% to 15% of traumatic thoracolumbar fractures. Treatment depends on the extent of ligamentous involvement: osseous/Magerl type B2 injuries can be managed conservatively, while ligamentous/Magerl type B1 injuries undergo stabilization with arthrodesis. Minimally invasive surgery without arthrodesis can achieve similar outcomes to open procedures. This has been studied for burst fractures; however, its role in FDI is unclear. OBJECTIVE: To conduct a systematic review of the literature that examined minimally invasive surgery instrumentation without arthrodesis for traumatic FDI of the thoracolumbar spine. METHODS: Four electronic databases were searched, and articles were screened using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines for patients with traumatic FDI of the thoracolumbar spine treated with percutaneous techniques without arthrodesis and had postoperative follow-up. RESULTS: Seven studies with 44 patients met inclusion criteria. There were 19 patients with osseous FDI and 25 with ligamentous FDI. When reported, patients (n = 39) were neurologically intact preoperatively and at follow-up. Osseous FDI patients underwent instrumentation at 2 levels, while ligamentous injuries at approximately 4 levels. Complication rate was 2.3%. All patients had at least 6 mo of follow-up and demonstrated healing on follow-up imaging. CONCLUSION: Percutaneous instrumentation without arthrodesis represents a low-risk intermediate between conservative management and open instrumented fusion. This “internal bracing” can be used in osseous and ligamentous FDIs. Neurologically intact patients who do not require decompression and those that may not tolerate or fail conservative management may be candidates. The current level of evidence cannot provide official recommendations and future studies are required to investigate long-term safety and efficacy.

Minimally Invasive Spine

The concept of minimally invasive surgery has gained increasing popularity in the last several decades, are being introduced as an alternative to limit the surgical complications while achieving best possible outcome. While minimally invasive spine surgery holds promise for lower blood loss, faster patient recovery, shorter hospital stays, and the potential to transition procedures to the ambulatory setting, safety in spinal surgery remains paramount and has (appropriately) tempered some of the enthusiasm for the results of aggressive early adapters. Until now, there has been no literature summarizing the evidence of MIS outcome in treating spondylitis TB of the bone. The purpose of this systematic review was to investigate the outcome of minimal invasive surgery approach for spine infection. authors comprehensively searched PubMed, EMBASE, and Cochrane Library to search for studies about minimally invasive surgery as management of tuberculous spondylitis up to June 7th, 2019. The selection of appropriate studies was performed by independent investigators based on PRISMA guideline. Given the limited number of studies, there was no restriction in terms of patient’s demographics, the specific minimal invasive surgical method, and publication status. Authors identified the method for minimally invasive approach and open approach, the functional outcome, intraoperative outcome, radiological outcome, length of stay, follow up period, and complication. Authors found 81 articles from database. After evaluating full text, 8 articles (346 patients) were found to be eligible. More than 110 patients were treated with open spine surgery, while more than 270 patients were treated using minimally invasive spine surgery the minimal invasive methods were posterior pedicle screws fixation, plate fixation, lateral nail bar fixation, and bilateral pedicle screw fixation. The visualization methods include C-arm fluoroscopy, X-ray fluoroscopy. The follow-up period ranges from 1 to 40 months. The functional outcome were found to be satisfying with minimal complications. MIS yielded satisfactory result in comparison to conventional open surgery for spine infection. More long term future studies should be conducted to in order to search for more solid evidence regarding this claim.
