Minimally Invasive Surgery: A Paradigm Shift in Surgical Procedures

Minimally Invasive Surgery (MIS) and microsurgery have significantly transformed periodontal treatment by reducing tissue trauma and improving patient outcomes. MIS focuses on minimizing flap reflection and tissue manipulation, preserving blood supply, and ensuring the stability of blood clots at the wound site, which collectively reduce postoperative complications such as shrinkage and discomfort. Microsurgery, enabled by advancements in surgical microscopes, enhances visual acuity and allows for precise surgical interventions. In periodontology, the integration of MIS and microsurgery has led to refined surgical techniques that prioritize minimal tissue disruption, passive wound closure, and the use of specialized microsurgical instruments. These approaches offer significant advantages over conventional flap surgeries, which were often associated with extensive tissue damage, prolonged healing times, and aesthetic compromises. The evolution of MIS in periodontology represents a shift from resection-based procedures to those focused on regeneration, emphasizing the importance of skill enhancement and the adoption of advanced technologies. As MIS techniques continue to develop, they hold the potential to become the standard of care, providing patients with effective, less invasive treatment options that result in better clinical and aesthetic outcomes. The current article's goal was to gather and record different minimally invasive periodontology techniques. Peer-reviewed materials from journals, Medline/PubMed, Google Scholar, and other reviews served as the foundation for the research.

Minimally Invasive Surgery for Hirschsprung Disease: Current Practices and Future Directions.

Hirschsprung disease (HD) is a congenital disorder characterized by the absence of ganglion cells in the distal colon and rectum, leading to functional obstruction and severe constipation. Over the past decades, the surgical management of HD has significantly evolved, with minimally invasive surgery (MIS) techniques revolutionizing treatment approaches. This review explores recent innovations in MIS for HD, focusing on laparoscopic, transanal endorectal pull-through (TERPT), and robotic-assisted techniques. These approaches offer numerous advantages over traditional open procedures, including reduced surgical trauma, improved cosmesis, faster recovery times, and potentially lower complication rates. Laparoscopic surgery has become widely adopted, providing excellent visualization and precise dissection. TERPT has gained popularity for short-segment disease, offering a completely transanal approach with minimal scarring. Robotic-assisted surgery represents the cutting edge, enhancing surgical precision and dexterity. The review also examines emerging technologies and future directions, such as advanced imaging techniques, artificial intelligence applications, and potential developments in tissue engineering. While MIS techniques have shown promising outcomes, challenges remain in standardizing approaches, addressing long-segment disease, and optimizing long-term functional results. The future of HD surgery lies in personalized approaches that integrate genetic and molecular profiling with advanced surgical technologies. As the field continues to evolve, comprehensive long-term studies and efforts to improve access to specialized care will be crucial to further enhancing outcomes for patients with HD.

Usability of Minimal Invasive Surgery for Elbow Dislocation with Coronoid Process Fracture: A Protocol Development Study.

The study aims to explain whether or not minimal invasive surgery (MIS) would be feasible in elbow fracture-dislocation with coronoid process fracture. At Taipei Veterans General Hospital, patients who had elbow dislocations with coronoid process fractures underwent a single surgeon's MIS techniques which included the fluoroscopy-guided ulnar anteromedial (FGUAM) approach in the stage of reducing the coronoid process. When there is a proximal ulnar fracture, the posterior incision should be necessary, followed by the incision over the lateral or medial elbow for treating radial fractures or ligament injuries. The Flow Diagram for approach recommendation was established on the basis of defining MIS as that which does not include cross-plane dissection. The importance of anterior rigid fixation for the coronoid process was also emphasized. MIS can be achieved by multiple limited surgical incisions. Although the posterior extensile approach is necessary in situations of ulnar metaphysis or ligament avulsion fracture, the FGUAM approach decreases the cross-plane dissection.

Assessing the Fractional Curve for Proper Management of Adult Degenerative Scoliosis.

Adult degenerative scoliosis (ADS) is a coronal plane deformity often accompanied by sagittal plane malalignment. Surgical correction may involve the major and/or distally-located fractional curves (FCs). Correction of the FC has been increasingly recognized as key to ameliorating radicular pain localized to the FC levels. The present study aims to summarize the literature on the rationale for FC correction in ADS. Three databases were systematically reviewed to identify all primary studies reporting the rationale for correcting the FC in ADS. Articles were included if they were English full-text studies with primary data from ADS ( ≥ 18 years old) patients. Seventy-four articles were identified, of which 12 were included after full-text review. Findings suggest FC correction with long-segment fusion terminating at L5 increases the risk of distal junctional degeneration as compared to constructs instrumenting the sacrum. Additionally, circumferential fusion offers greater FC correction, lower reoperation risk, and shorter construct length. Minimally invasive surgery (MIS) techniques may offer effective radiographic correction and improve leg pain associated with foraminal stenosis on the FC concavity, though experiences are limited. Open surgery may be necessary to achieve adequate correction of severe, highly rigid deformities. Current data support major curve correction in ASD where the FC concavity and truncal shift are concordant, suggesting that the FC contributes to the patient's overall deformity. Circumferential fusion and the use of kickstand rods can improve correction and enhance the stability and durability of long constructs. Last, MIS techniques show promise for milder deformities but require further investigation.

Laparoscopy and thoracoscopy in small animal surgery: A 2020 survey of small animal diplomate and resident veterinary surgeons.

To document the utilization and training of laparoscopic and thoracoscopic minimally invasive surgery (MIS) techniques within the American, European, Australian and New Zealand Colleges of Small Animal Veterinary Surgeons (ACVS, ECVS, and ANZCVS) in 2020. Observational study. Diplomates and residents of the ACVS, ECVS, and FANZCVS. An electronic survey was sent using veterinary list servers. Questions were organized into categories evaluating (1) the demographics of the study population and the caseload, (2) comfort level with specific procedures, (3) motivating factors and limitations, and (4) surgical training and the role of the governing bodies. Respondents included 111 practicing surgeons and 28 residents. Respondents' soft-tissue MIS caseloads had increased since they first started performing MIS; however, most respondents were only comfortable performing basic laparoscopy. Over half of the respondents agreed on the patient benefits and high standard of care provided by MIS. Perceived adequate soft-tissue training in MIS during residency was strongly associated with perceived proficiency at the time of survey response. Most respondents agreed that the specialty colleges should take a more active role in developing standards for soft-tissue MIS, with residents agreeing that a required standardized course would be beneficial. Soft-tissue MIS is widely performed by diplomates and residents. Perceived adequate soft-tissue MIS training was strongly associated with perceived proficiency. There is substantial underutilization of advanced MIS techniques in veterinary specialty surgical practice, which might be improved by a stronger focus on MIS training during residency.

Fourth Generation Hallux Valgus Correction

Abstract: The surgical method described in this paper has shown numerous benefits when compared with traditional minimally invasive surgery (MIS) techniques for the correction of hallux valgus. Although modern, third-generation MIS techniques have been widely adopted for this purpose due to perceived improvements in patient outcomes, those can be largely attributed to the incorporation of a novel system of rigid internal fixation allowing for a reduced risk of surgical complications. By incorporating the second-generation MIS technique of transverse osteotomy with third-generation fixation techniques, the authors have been able to devise a hybrid, fourth-generation MIS technique that shows improvements both in terms of patient recovery and ease of surgical operation. Level of Evidence: The mechanism-based reasoning used in this study classifies it as diagnostic level V in accordance with the OCEBM 2011 Levels of Evidence. For a complete description of levels of evidence, see Instructions for Authors.

Spectrum of Minimally Invasive Surgical Techniques for the Managment of Inguinal Hernias in Infants and Children

One of the most common surgical procedures in infants and children is the repair of an indirect inguinal hernia. This can be carried out by open technique or using minimally invasive surgery (MIS). Since 1998, numerous different MIS techniques have been described. Scientifically proven advantages include a shorter operation time for bilateral hernias, along with a lower risk of metachronal, contralateral hernia. Nevertheless, the proportion of inguinal hernias treated using MIS in children in this country is relatively low, at around 8% of all operations. The aim of this synopsis is to describe the different MIS techniques for inguinal hernia repair in children, including their respective advantages and disadvantages.This video compilation shows the spectrum of different techniques for laparoscopic inguinal hernia repair in children. It includes the intracorporeal suturing technique, the incision of the peritoneum, extracorporeal percutaneous techniques, and the cauterisation of the open peritoneal vaginal process in girls.Although minimally invasive inguinal hernia repair in children is technically and scientifically established, it is not yet being widely used. This video manuscript provides an overview of the various techniques, thus facilitating clinical application.

The Use of Minimally Invasive Surgery in the Treatment of Crohn's Disease: A Systematic Review of Evidence

Minimally invasive surgery (MIS) is a groundbreaking approach for treating Crohn's disease (CD), affecting approximately 100-300 per 100,000 people. In 2015, an estimated 3.1 million people were diagnosed with Inflammatory Bowel Disease (IBD). Our research aims to consolidate previous evidence on MIS techniques, including laparoscopic techniques and robotic-assisted surgery, and compare them to traditional surgical techniques in managing CD. The practical benefits of MIS are evident in comparative studies, which consistently show that laparoscopic approaches result in shorter hospital stays and faster recovery than open surgery. MIS also demonstrates significant long-term benefits, particularly in reducing the mortality rate. Even pediatric CD patients have shown improved outcomes with laparoscopic-assisted surgery, experiencing fewer postoperative complications and better recovery. MIS applications include Laparoscopic ileocolic resections, a key MIS technique, offer comparable outcomes to other therapies like open ileocolic resection but with the added advantages of lower costs and long-term disease control. This cost-effectiveness of MIS techniques is a significant advantage. Techniques like intracorporeal anastomosis and trans colonic specimen removal have further improved postoperative recovery and cosmesis. Strictureplasty is another MIS technique, is particularly beneficial for CD patients with strictures due to its ability to preserve intestinal length and function. Lastly, laparoscopic robotic-assisted surgery is a game-changer, offering a significant reduction in postoperative pain and faster recovery compared to manual surgeries.

Minimally Invasive Technique for Chiari I Decompression Without Durotomy: Surgical Technique and Preliminary Case Series

BackgroundChiari I malformation, marked by severe headaches and potential brainstem/spinal cord issues, often requires surgical intervention when conservative methods fail. This study introduces a minimally invasive surgery (MIS) Chiari decompression technique utilizing a 3-blade retractor, aiming to reduce post-operative discomfort and optimize outcomes. MethodsChiari type 1 malformation patients who underwent a MIS technique were included. Technique consisted of a minimal- soft tissue opening using a 3-blade retractor, suboccipital craniectomy, C1 laminectomy, and resection of the atlantooccipital band without a durotomy. Results10 patients were treated. Mean age was 43.3 years with 7 females. All patients presented occipital headaches, 50% retroorbital pain, 40% neck, upper back or shoulder pain, and 30% limb paresthesias. Median pre-surgical modified Rankin Scale (mRS) was 3 (2-4) and pain visual analog score (VAS) was 7 (5-9). Mean operative time was 59 (59-71) min, with mean blood loss of 88.5 (50-140) mL. 90% of patients were discharged the same surgical day (mean 7.2 [5.3-7.7] hours post-op). No immediate or delayed post-operative complications were evidenced. At 6-months, 90% of patients had mRS 0-1. At last follow-up the VAS mean was 1.5 (range 0-4, p<0.001). ConclusionThe MIS 3-blade flexible retractor technique for Chiari decompression is feasible, provides wide visualization angles of the suboccipital region and C1 arch, allows 2-surgeon work, and minimizes skin and soft tissue disruption. This combination may diminish post-operative discomfort, reduce the risk of surgical site infections, and optimize outcomes.

Evidence-based advances in minimally invasive surgery in infants with congenital gastrointestinal anomalies: a narrative review.

Minimally invasive surgery (MIS) has been widely utilized to manage congenital gastrointestinal (GI) anomalies in children during the last two decades. Currently, MIS has a proven track-record for its feasibility and provides multiple benefits including better cosmesis, less trauma, and faster recovery in neonates and infants. However, it remains controversial whether MIS provides better definitive outcomes in pediatric patients with GI anomalies, especially among neonates. We aim to review the recent developments of MIS in infants with GI defects, assisting surgeons in making decisions and improving patient outcomes. A comprehensive literature search of PubMed and Web of Science's core collection was performed using terms of MIS techniques and congenital GI anomalies. This review summarizes recent evidence-based advances of MIS in infants with congenital GI defects and potential future strategies based on evidence. Better cosmetic results, less postoperative pain, and an accelerated recovery have been shown to be common advantages of MIS relative to open approaches. Technical hurdles and metabolic disturbance were reported to be the main reasons for the decisions of open approach. Advanced techniques of MIS have made more precise manipulations and better outcomes possible, even for newborns. At the same time, surgeons should not be afraid to use an open approach in certain circumstances due to technical limitations or patient tolerance. The difficulty infants face in expressing their true feelings underscores the need for systematic and objective assessment tools to evaluate surgical outcomes.

Displacement after Open vs Saw-Based Minimally Invasive Medial Displacement Calcaneal Osteotomy: A Cadaveric Study.

Medial displacement calcaneal osteotomy (MDCO) is routinely used in hindfoot valgus realignment. Minimally invasive surgery (MIS) calcaneal osteotomies have been reported to be as safe and effective compared to open techniques. The aim of this cadaveric study was to compare the amount of medial tuberosity displacement obtained with fine-cut saw-based MIS vs open MDCO techniques. Eight matched cadaveric specimens had one side randomly assigned to either open or MIS MDCO. The contralateral limb was then assigned to the alternative osteotomy. The amount of medial displacement provided by the osteotomy was measured manually using a flexible metric ruler and radiographically on standardized axial calcaneal radiographs. Manual measurements showed that a mean displacement of the MIS osteotomy was 7.9 mm compared with 8.7 mm for the open technique (P = .36). Radiograph measurement showed a mean displacement of the MIS osteotomy was 7.1 mm compared with 7.4 mm for the open technique (P = .83). No significant difference was found on manual and radiographic measurement of medial displacement between MIS and open MDCO. In a cadaveric model, we found similar magnitude of calcaneal tuberosity displacement using fine-cut saw-based MIS and open techniques for medial displacement calcaneal osteotomies. Level V, cadaveric study.

MIS technique for separation surgery in lumbar spine metastatic disease.

Around 40% of cancer patients present with spinal metastases (SM), the lumbar spine being the second most involved site (15%-30%) after the thoracic (60%-80%). Since the development of separation surgery, minimally invasive surgery (MIS) has increasingly been applied to approach SM, mirroring benefits yielded in the degenerative realm. Moreover, preoperative embolization potentially enhances local control for certain radioresistant histologies. Carbon fiber-reinforced PEEK hardware reduces image artifact, facilitating more accurate follow-up and radiotherapeutic planning. Additionally, short-segment cement-augmented constructs may be beneficial to decrease surgical morbidity and operative risk in this population. The authors present a lumbar spinal metastasis treated with MIS techniques. The video can be found here: https://stream.cadmore.media/r10.3171/2024.1.FOCVID23222.

Early outcome of minimally invasive repair of tetralogy of fallot via right vertical infra-axillary incision

Background: Recently, several authors have detailed their experiences with small cohorts of patients in using minimal invasive surgery (MIS) to treat Tetralogy of Fallot (TOF) with innovative approaches and satisfactory results. The goal of this study was to review an new innovative MIS technique that results in using minimal right vertical infra-axillary incision (RVIAI). &#x0D; Methods: Our retrospective study reviewed 45 patients that were diagnosed with TOF and underwent minimally invasive surgery through RVIAI at Children City Hospital from June 2020 to June 2023. &#x0D; Results: Mean age was 9,4 ± 6,6 months, mean body weight was 7,4 ± 1,7 kg, the male/female ratio was 2,1/1. Mean size of pulmonary annulus was 9,58 ± 1,53 mm (-0,47 ± 1,04 Zscore). Central cannulation was accessed in all patients. There were no deaths or conversions to sternotomy. Average durations of aortic cross-clamp and cardiopulmonary bypass (CPB) were 188,7 ± 50,6 min and 124,6 ± 35,8 min, respectively. During the follow-up of 5.4–32.3 months, 11,1% of these patients were found to have moderate residual pulmonary stenosis. There was no severe residual pulmonary stenosis, residual shunt, severe tricuspid regurgitation. No reoperation, no new onset of chest deformities and no sclerosis were observed during the follow-up.&#x0D; Conclusions: The right axillary incision allows a safe and effective approach for Tetralogy of Fallot complete repair and is a potential new standard of care for many patients.

Role of lateral soft tissues release in percutaneous hallux valgus correction: A medium term retrospective study.

In the field of minimally invasive surgery (MIS) for the treatment of hallux valgus (HV), different techniques have begun to emerge in the literature concerning the distal osteotomy of the first metatarsal bone, the synthesis or not of the metatarsal head, the possible association with lateral soft tissues release (LSTR) and osteotomy of the base of the first phalanx. To evaluate the role of LSTR on percutaneous HV correction, evaluating functional and radiographical results. From January 2012 to May 2016 a total of 396 patients with mild to moderate symptomatic HV treated with the MIS technique were included in this retrospective study. The technique provides no internal fixation (WOS). Patients were divided into the LSTR group and no LSTR group (LSTR N). This surgical procedure (LSTR) was reserved for insufficient HV angle (HVA) correction during fluoroscopic control. Patients were evaluated at each follow-up by two other authors after appropriate training by senior authors (first practitioners). Clinical evaluation was performed before surgery, 6 mo after surgery, and 48 mo follow-up. American Orthopaedic Foot and Ankle Society (AOFAS) and visual analog scale (VAS) score was used to evaluate pain and function, and complications were recorded. In addition, the incidence of relapses and the degree of joint range of motion (ROM) with the association with the LSTR (capsule, adductor tendon, phalanx-sesamoid ligament, and the deep transverse metatarsal ligament) were evaluated. Radiological parameters included HVA and intermetatarsal angle (IMA). Patient satisfaction was assessed. Student t-test and Fisher exact test were used to assess statistical analysis. From our study it is clear that no differences in term of HVA, VAS, IMA correction, rate of complications, and AOFAS score were found between groups, while a significant improvement of the same variables was found in each group between pre and postoperative values. A significant improvement in ROM at 6 mo (P = 0.018) and 48 mo (P = 0.02) of follow-up was found in LSTR N group. Complications were rare in both groups. LSTR procedure on percutaneous HV correction seems to increase postoperative joint stiffness with a comparable incidence of relapse and a low incidence of complications.

Application of SLAM technology combined with AR in minimally invasive surgery

Minimally invasive surgery (MIS) is revolutionizing the medical field, offering patients faster recovery times and reduced risk of complications. However, MIS demands precise navigation and visualization of the surgical site, which can be challenging due to the limited field of view and constrained working space. In this study, we investigate the integration of simultaneous localization and mapping (SLAM) technology with augmented reality (AR) to enhance the capabilities of MIS and improve surgical outcomes. SLAM technology enables real-time 3D mapping and tracking of the surgical environment, while AR overlays crucial information, such as anatomical structures and surgical guidance, onto the surgeon's view. The proposed system combines these technologies to create a comprehensive, interactive representation of the patient's anatomy, providing surgeons with a more intuitive and accurate understanding of the surgical site. We assess the performance of the integrated SLAM-AR system based on a review of relevant literature, focusing on its accuracy, usability, and impact on surgical efficiency. The findings suggest that the SLAM-AR system has the potential to significantly improve spatial awareness and navigation during MIS, potentially reducing procedure times and complication rates. Furthermore, the system shows promise for enhancing surgeon training and promoting the adoption of MIS techniques in various surgical fields.

Are complications after repairing acute Achilles tendon ruptures related to the surgical approach or the patient’s comorbidities?*

Objective: Analyze the postoperative complications after repairing acute Achilles tendon rupture and compare them according to the surgical approach (open surgery (OS) or minimally invasive surgery (MIS)) and the patient’s comorbidities. Methods: A retrospective analytical study including 154 consecutive patients with an acute Achilles tendon rupture submitted to surgery and divided into OS and MIS cohorts. The following relevant comorbidities were analyzed: obesity, diabetes mellitus, smoking, dyslipidemia, gout, chronic corticosteroid use, connective tissue pathologies, transplant history, cancer treatment patients, and postoperative complications. Results: Seventy-eight patients (50.6%) were treated surgically with an OS technique and 76 (49.4%) with an MIS approach. Twenty patients (13%) had postoperative complications between the two cohorts (OS 11.5%; MIS 14.5%; p = 0.588). No statistically significant difference was found in the logistic regression of the risk of the surgical approaches and complications. Obesity had a significant statistical difference when complications and comorbidities were compared. Conclusions: Patients with obesity have a higher risk of developing postoperative complications with both OS and MIS techniques. No relationship was found between the type of surgical approach and a higher percentage of postoperative complications in treating acute Achilles tendon rupture.

Laparoscopic Completion Total Gastrectomy for Remnant Gastric Cancer Compared to Laparoscopic Total Gastrectomy in Short- and Medium-Term Results.

Introduction: The incidence of remnant gastric cancer is increasing in recent years. The advantages of minimally invasive surgery for gastric cancer are well established. However, laparoscopic completion total gastrectomy for remnant gastric cancer harbors difficulties due to adhesions, changed configuration of the anatomical organs, and changes on the lymphatic flow. We aim to investigate the feasibility, safety, and the short-term outcomes of laparoscopic completion total gastrectomy compared to laparoscopic total gastrectomy. Materials and Methods: All patients who underwent total gastrectomy from January 2018 to December 2021 at Shamir Medical Center were included in the study. Patients were divided into two groups-completion gastrectomy and total gastrectomy. The groups were compared for demographics, operative, and clinical outcomes. Results: Overall, 22 patients were included in the study. Eight were completion gastrectomy following subtotal gastrectomy for malignancy and 14 were primary total gastrectomy. All operations were performed by minimal invasive surgery technique. Average age was 64 years, with no differences in gender. Two major intraoperative complications were noted in completion group (25% versus 0%, P = .12). Both length of surgery (3:03 versus 3:40, P = .049) and length of stay (7 days versus 9 days, P = .5) were shorter in completion group. There were fewer postoperative complications (12.5% versus 28.5%, P = .61). Average number of harvested lymph nodes was significantly lower in completion group (10 versus 33, P = .002). Conclusion: Laparoscopic completion total gastrectomy for remnant gastric cancer is safe and feasible having comparable oncological surrogate's parameters and recurrence profile. Clinical Registration Number: 0015-22-ASF.

“Selection, planning and execution of minimally invasive surgery in adult spinal deformity correction”

Minimally invasive surgery (MIS) for correction of adult spinal deformity was developed to address the high rate of medical and surgical complications rate in open surgical treatment of increasingly aging and frail patient population. In the past decade, MIS group within the International Spine Study Group (ISSG) has been in the forefront of the application of MIS techniques to fulfill the well-established principles of ASD surgery. These efforts have resulted in landmark studies. Here, we review these studies that encompass all aspects of MIS surgical treatment of ASD including patient selection with Minimally Invasive Spinal Deformity Surgery (MISDEF) and MISDEF-2 algorithms, surgical planning with anterior column realignment classification and the Minimally Invasive Interbody Selection Algorithm (MIISA), and surgical execution with Spinal Deformity Complexity Checklist (SDCC). We will highlight that with careful selection, diligent planning and meticulous execution the MIS techniques can treat patients with ASD, abiding to correction principles and radiographic parameters.

Surgical evolution in spinal dural arteriovenous fistula treatment-a 7 years monocentric experience.

Accounting for 70% of all spinal vascular malformations, spinal dural arteriovenous fistulas (SDAVF) are the most common type of malformation. Interruption of the fistulous arterialized vein point is the goal of surgical treatment. The aim of the study was to compare open surgery (laminectomy) versus minimal invasive surgery (MIS) in SDAVF treatment. Between March 2013 and March 2020, we retrospectively collected 21 consecutive adult patients with SDAVF. Since March 2017, MIS has been routinely used for surgical treatment. Pre- and post-operative clinical evaluations used Aminoff-Logue score (ALS). Complication rate was noted. Post-operative occlusion of the malformation was confirmed by digital subtraction angiography (DSA) in all patients. MIS was compared to open surgery in terms of efficacy and complications with statistical evaluation. Standard laminectomy was performed in 12 patients and MIS technique in 9 patients. No difference was noted on pre-operative parameters. ALS and MRI signs of myelopathy were improved in all cases except for 1 patient in each group. All SDAVFs were excluded based on post-operative DSA. Significant differences were noted between the 2 groups in terms of perioperative blood loss (p<0.001), post-operative pain visual analog scale values (p<0.001), and first time out of bed (p<0.001). Wrong level surgery occurred in one patient in each group; patients were re-operated using the same technique. No infection or cerebrospinal fluid (CSF) leak was noted. In our experience, MIS is a safe alternative to open laminectomy for SDAVF treatment. MIS contributes to patient comfort and minimizes blood loss without increasing complication rate.

Clinical and functional outcomes of open versus minimally invasive surgeries in single-level prolapsed intervertebral disc in lumbar region at tertiary care center: A prospective study

Background: Spine surgery has been transformed significantly by the growth of minimally invasive surgery (MIS) procedures. Modern MIS techniques allow spine surgeons to achieve the same goals of open surgery while minimizing the collateral damage associated with the open approaches. Aims and Objectives: The aim of MIS is to do an efficient “Target Surgery” with a minimum of iatrogenic trauma. Materials and Methods: This is a prospective study done in the Department of Neurosurgery, JA group of hospitals, Gajra Raja Medical College, Gwalior, from July 2021 to July 2022. Study was conducted on 30 randomly selected patients whose presentation and imaging showed indication for surgery. Results: Better symptomatic relief was seen in patients with MIS at 7 days with about 80% of them having a visual analog scale score between 0 and 2; however, not much difference was noted at 1 month. Not much difference was noted for wound status, neurological improvement, and Oswestry Disability Index at 1 month. However, gross difference was noted at the rate of return to work by the patients with approximately 93.3% of patients undergoing MIS returning to work within 1 month in comparison to only 20% in case of open surgery. Conclusion: Minimally invasive techniques are remarkably better option to traditional open surgeries, as these procedures showed a significant reduction in immediate post-operative pain, duration of hospital stay, and return to work by the patient. However, not much difference was noted in status of pain at 1 month, rehospitalization, degree of disability at 1 month, wound status, and neurological improvement of the patient.
