Minimally Invasive Surgery for Adolescent Idiopathic Scoliosis: A Systematic Review.

Background: Minimally invasive surgical (MIS) techniques have gained popularity as a safe and effective alternative to open surgery for degenerative, traumatic, and metastatic spinal pathologies. In adolescent idiopathic scoliosis, MIS techniques comprise anterior thoracoscopic surgery (ATS), posterior minimally invasive surgery (PMIS), and vertebral body tethering (VBT). In the current systematic review, the authors collected and analyzed data from the available literature on MIS techniques in AIS. Methods: The articles were shortlisted after a thorough electronic and manual database search through PubMed, EMBASE, and Google Scholar. Results: The authors included 43 studies for the review; 14 described the outcomes with ATS, 13 with PMIS, and 16 with VBT. Conclusions: While the efficacy of the ATS approach is well-established in terms of comparable coronal and sagittal correction to posterior spinal fusion, the current use of ATS for instrumented fusion has become less popular due to a steep learning curve, high pulmonary and vascular complication rates, implant failures, and increased non-union rates. PMIS is an effective alternative to the standard open posterior spinal fusion, with a steep learning curve and longer surgical time being potential disadvantages. The current evidence, albeit limited, suggests that VBT is an attractive procedure that merits consideration in terms of radiological correction and clinical outcomes, but it has a high complication and re-operation rate, while the most appropriate indications and long-term outcomes of this technique remain unclear.

[Minimally-Invasive Surgical Techniques (MIST): Shedding Light on the Mist].

As life expectancy increases and there is growing demand for BPH treatments, innovative technologies have been developed, allowing for swift recovery, symptom relief, low complication rates, and the possibility of performing procedures on an outpatient basis, often under local anaesthesia. This review aims to describe the outcomes of newly developed minimally-invasive surgical therapies (MIST) for BPH treatment in terms of functional voiding parameters and sexual function. These therapies are categorized into primarily ablative (Aquablation [Aquabeam]), non-ablative (Prostatic Urethral Lift (PUL, Urolift), temporary implantable devices [iTind]), and secondarily ablative procedures (convective water vapor ablation, Rezum, Prostate Artery Embolization [PAE]). All MIST technologies have advanced the medical care of patients with BPH while preserving ejaculation. However, there is a shortage of long-term data specifically addressing re-intervention rates and the preservation of functional voiding parameters. Although there is promising data from regulatory trials and randomized studies, all MIST therapies are potentially associated with severe complications. Patients considering such methods must be thoroughly informed about their inferiority compared with established transurethral procedures like TUR-P and enucleation.

Assessing Knowledge Gaps in Minimal Invasive Surgical Techniques : A Survey of Surgical Residents

Background: Minimal invasive surgical techniques have gained prominence for their safety and efficiency compared to traditional open surgeries. These techniques, including laparoscopy and robotic-assisted surgery, offer advantages such as reduced postoperative pain and shorter hospital stays. However, successful adoption relies on extensive training and knowledge among surgical residents. Materials and Methods: This cross-sectional survey study was conducted among surgical residents in Muzaffarpur, Bihar, India. Stratified random sampling ensured representation from government and private healthcare institutions. A structured questionnaire collected data on demographic information, knowledge levels, training experiences, and perceived knowledge gaps. Data were analyzed using descriptive and inferential statistics. Results: Among 50 participants, 80% received formal training, 70% attended workshops/seminars, and 96% observed live surgeries in minimally invasive techniques. However, only 60% had hands-on experience. Perceived knowledge gaps included lack of hands-on training (24\%), limited exposure to complex cases (36%), and difficulty in applying techniques (24%). Knowledge levels improved with years of residency, which is consistent with Indian studies. Conclusion: Addressing knowledge gaps and enhancing training in minimally invasive surgery is essential for surgical residents in Muzaffarpur. Increasing hands-on opportunities, diverse case exposure, and mentorship programs can improve proficiency and patient outcomes.

European society for trauma and emergency surgery member-identified research priorities in emergency surgery: a roadmap for future clinical research opportunities.

European Society for Trauma and Emergency Surgery (ESTES) is the European community of clinicians providing care to the injured and critically ill surgical patient. ESTES has several interlinked missions - (1) the promotion of optimal emergency surgical care through networked advocacy, (2) promulgation of relevant clinical cognitive and technical skills, and (3) the advancement of scientific inquiry that closes knowledge gaps, iteratively improves upon surgical and perioperative practice, and guides decision-making rooted in scientific evidence. Faced with multitudinous opportunities for clinical research, ESTES undertook an exercise to determine member priorities for surgical research in the short-to-medium term; these research priorities were presented to a panel of experts to inform a 'road map' narrative review which anchored these research priorities in the contemporary surgical literature. Individual ESTES members in active emergency surgery practice were polled as a representative sample of end-users and were asked to rank potential areas of future research according to their personal perceptions of priority. Using the modified eDelphi method, an invited panel of ESTES-associated experts in academic emergency surgery then crafted a narrative review highlighting potential research priorities for the Society. Seventy-two responding ESTES members from 23 countries provided feedback to guide the modified eDelphi expert consensus narrative review. Experts then crafted evidence-based mini-reviews highlighting knowledge gaps and areas of interest for future clinical research in emergency surgery: timing of surgery, inter-hospital transfer, diagnostic imaging in emergency surgery, the role of minimally-invasive surgical techniques and Enhanced Recovery After Surgery (ERAS) protocols, patient-reported outcome measures, risk-stratification methods, disparities in access to care, geriatric outcomes, data registry and snapshot audit evaluations, emerging technologies interrogation, and the delivery and benchmarking of emergency surgical training. This manuscript presents the priorities for future clinical research in academic emergency surgery as determined by a sample of the membership of ESTES. While the precise basis for prioritization was not evident, it may be anchored in disease prevalence, controversy around aspects of current patient care, or indeed the identification of a knowledge gap. These expert-crafted evidence-based mini-reviews provide useful insights that may guide the direction of future academic emergency surgery research efforts.

Minimally invasive techniques in quest of Holy Grail of surgical management of enlarged prostates: a narrative review.

Past decade has seen a renewed interest in minimally invasive surgical techniques (MISTs) for management of enlarged prostate. This narrative review aims to explore newer MIST for benign prostatic hyperplasia (BPH) which are not yet integrated into established societal guidelines. We conducted a literature search across PubMed, Google Scholar, and FDA ClinicalTrials.gov databases on June 1st, 2023, to identify studies published within the past decade exploring various MISTs for BPH. Additionally, we gathered insights from abstracts presented in meetings of professional associations and corporate websites. We broadly classified these procedures into three distinct categories: energy-based, balloon dilation, and implant/stent treatments. We collected detail information about the device, procedure details, its inclusion and exclusion criteria, and outcome. Our review reveals that newer energy-based MISTs include Transperineal Laser Ablation, Transurethral Ultrasound Ablation, and High-Intensity Focused Ultrasound. In the sphere of balloon dilation, Transurethral Columnar Balloon Dilation and the Optilume BPH Catheter System were gaining momentum. The noteworthy implants/stents that are on horizon include Butterfly Prostatic Retraction Device, Urocross Expander System, Zenflow Spring System, and ProVee Urethral Expander System. The exploration of various MISTs reflects ongoing efforts to enhance patient care and address limitations of existing treatments. This review provides a bird-eye view and valuable insights for urologists and researchers seeking to navigate the dynamic landscape of MISTs in the quest for effective and minimally invasive solutions for enlarged prostates.

Minimally invasive periodontal regeneration with the buccal approach: a systematic review and meta-analysis of clinical studies.

The aim of this study was to investigate clinical periodontal parameters after treatment using the Minimally Invasive Surgical Technique (MIST), Modified Minimally Invasive Surgical Technique (M-MIST), and/or any technique for papilla preservation, such as Entire Papilla Preservation (EPP), modified-papilla preservation technique (M-PPT), or simplified-papilla preservation technique (SPPT). The focus question was "For patients with periodontal intrabony defects (P), what is the best minimally invasive regenerative approach (I), comparing MIST, M-MIST, and papilla preservation techniques' outcomes (C) to improve PD, CAL, GR, and periodontal stability(O)?" An online search was conducted on PubMed, Cochrane Library, and Embase. Only randomized clinical trials and case series with a minimum of 10 enrolled patients were included. The risk of bias was evaluated using the Critical Appraisal tools in JBI Systematic Reviews. The meta-analysis compared the data obtained for the periodontal parameters analyzed, and the heterogeneity was verified. After the screening, nine articles were included. Seven studies applied MIST and its modifications; two used M-PPT, one SPPT, and one approached EPP. A general statistically significant PD reduction and CAL gain were noted between the groups, comparing baseline and follow-up for all articles, independently of the technique or materials used. Also, all studies showed a non-significant increase in the gingival recession. Four studies had a low risk of bias, four had a moderate risk, and only 1 had a high risk. Moderate heterogeneity was found in one analysis for CAL (65.73%); moderate and substantial heterogeneity was found in the PD results (71.91% and 89.19%); and no heterogeneity was found within all analyses for gingival recession (0%). MIST, M-MIST, and papilla preservation techniques demonstrated their potential and efficacy to improve periodontal conditions of sites with intrabony defects with minimal morbidity.

Finite element analyses of three minimally invasive fixation techniques for treating Sanders type II intra-articular calcaneal fractures

Background and objectiveCalcaneal Sanders type II or III fractures are highly disabling with significant burden. Surgical treatment modalities include open reduction and internal fixation (ORIF) techniques and a variety of minimally invasive surgical (MIS) approaches. ORIF techniques are associated with complications and traditional MIS techniques need extensive intraoperative fluoroscopic procedures. The present study aims to investigate the effects of three different minimally invasive internal fixation (MIIF) techniques used to treat Sanders type II intra-articular calcaneal fractures using finite element analyses.MethodsA 64-row spiral computed tomography scan was used to observe the calcaneus of a healthy adult. The scanning data were imported into Mimics in a DICOM format. Using a new model of a Sanders type II-B intra-articular calcaneal fracture, three minimally invasive techniques were simulated. Technique A involved fixation using an isolated minimally invasive locking plate; Technique B used a minimally invasive locking plate with one medial support screw; and Technique C simulated a screw fixation technique using four 4.0-mm screws. After simulating a 640-N load on the subtalar facet, the maximum displacement and von Mises stress of fragments and implants were recorded to evaluate the biomechanical stability of different fixation techniques using finite element analyses.ResultsAfter stress loading, the maximum displacements of the fragments and implants were located at the sustentaculum tali and the tip of sustentaculum tali screw, respectively, in the three techniques; however, among the three techniques, Technique B had better results for displacement of both. The maximum von Mises stress on the fragments was < 56 Mpa, and stress on the implants using the three techniques was less than the yield strength, with Technique C having the least stress.ConclusionAll three techniques were successful in providing a stable fixation for Sanders type II intra-articular calcaneal fractures, while the minimally invasive calcaneal locking plate with medial support screw fixation approach exhibited greater stability, leading to improved enhancement for the facet fragment; however, screw fixation dispersed the stress more effectively than the other two techniques.

A comparison of Er,Cr:YSGG laser to minimally invasive surgical technique in the treatment of intrabony defects: Twelve-month results of a multicenter, randomized, controlled study.

The purpose of this publication is to report on the 12-month clinical and radiographic results comparing the surgical use of the Er,Cr:YSGG laser (ERL) and minimally invasive surgical technique (MIST) for the treatment of intrabony defects in subjects with generalized periodontitis stage III, grade B. Fifty-three adult subjects (29 females and 24 males; 19-73 years) with 79 intrabony defects were randomized following scaling and root planing (SRP) to receive ERL monotherapy (n=27) or MIST (n=26). Fifty subjects completed the study. Recession (REC), probing depth (PD), clinical attachment level (CAL), treatment time, and standardized radiographs were assessed and compared for each treatment group. Clinical measurements were recorded at baseline, 4-6weeks following SRP, and 6 and 12months following surgical therapy. Radiographic results were compared to baseline at 6 and 12months following surgical therapy. The following primary and secondary outcome variables were non-inferior with the following margins: CAL with a non-inferiority margin of 0.7 mm (p=0.05), PD with a non-inferiority margin of 0.7mm (p=0.05), and REC with a non-inferiority margin of 0.4mm (p=0.05). Standardized radiographs suggest similar bone fill of 1.14±1.73mm for MIST and 1.12±1.52mm for ERL. This is the first multicenter, randomized, masked, and controlled study demonstrating the ERL is not inferior to MIST at 12 months in terms of clinical outcomes and similar to MIST in terms of radiographic bone fill for the surgical treatment of intrabony defects.

Post-Operative Complications after Acute Achilles Tendon Rupture Repair: A Survival Analysis of Minimally Invasive vs Open Techniques

Category: Sports; Ankle Introduction/Purpose: Acute Achilles tendon ruptures (ATRs) can be treated surgically through either open repair or minimally invasive surgical techniques (MIS). While the relative complication rates between these techniques, including wound dehiscence, re-rupture, and sural nerve injury, have been debated, many studies demonstrate no significant difference between these two approaches. In this study, we conducted a Kaplan-Meier survival analysis to compare the incidence and timing of complications between open and MIS repair of acute ATRs and examine factors that may influence these rates. Methods: A retrospective study was conducted to evaluate the outcomes of patients (≥18 years) who underwent surgical intervention for acute ATR within a four-week period following injury, with a minimum follow-up of three months. Data on demographic variables, type of surgical procedure (MIS or open approach), and the occurrence and timing of postoperative complications were collected. Postoperative complications were classified as venous thromboembolism (VTE), re-rupture, surgical site infecti+D2on (SSI), wound dehiscence, and sural nerve injury.The Kaplan-Meier method was employed to compare the complication rates between the MIS and open repair groups. The log-rank test was used to test the equality of survivor functions. The Cox proportional hazards model was employed to determine predictors of complications. Results: In total, 417 patients were included in the final analysis. The MIS group had a higher proportion of patients with tobacco use. Fifty-two complications in 50 patients were recorded (Table 1). We found no significant difference in the complication rates between the MIS and open repair groups. However, Cox proportional hazards modeling revealed that body mass index (BMI) was a significant predictor of re-ruptures (HR 1.2, 95% CI = 1.05–1.4) and that surgical delay was found to be a significant predictor of wound dehiscence (HR 1.2, 95% CI =1.01–1.3) and sural nerve injury (HR 1.2, 95% CI =1.1–1.3). A surgical delay of more than 2 weeks was noted to have a positive likelihood ratio of 2.3 for wound dehiscence and 3.1 for sural nerve injury. Conclusion: The results of this study indicate that MIS and open repair techniques for acute ATRs demonstrate comparable complication rates. However, patients with elevated BMI exhibit an increased risk of re-rupture. Those with surgical delay beyond two weeks have an elevated likelihood of wound dehiscence and sural nerve injury, presumptively due to associated scaring and the requisite tissue manipulation. Surgeons and patients may consider these variables when formulating a surgical treatment plan.

Minimally Invasive Surgery in Non-Small Cell Lung Cancer: Where Do We Stand?

In the last two decades, robotic-assisted thoracoscopic surgery (RATS) has gained popularity as a minimally invasive surgical (MIS) alternative to multi- and uniportal video-assisted thoracoscopic surgery (VATS). With this approach, the surgeon obviates the known drawbacks of conventional MIS, such as the reduced in-depth perception, hand-eye coordination, and freedom of motion of the instruments. Previous studies have shown that a robotic approach for operable lung cancer has treatment outcomes comparable to other MIS techniques such as multi-and uniportal VATS, but with less blood loss, a lower conversion rate to open surgery, better lymph node dissection rates, and improved ergonomics for the surgeon. The thoracic surgeon of the future is expected to perform more complex procedures. More patients will enter a multimodal treatment scheme making surgery more difficult due to severe inflammation. Furthermore, due to lung cancer screening programs, the number of patients presenting with operable smaller lung nodules in the periphery of the lung will increase. This, combined with the fact that segmentectomy is becoming an increasingly popular treatment for small peripheral lung lesions, indicates that the future thoracic surgeons need to have profound knowledge of segmental resections. New imaging techniques will help them to locate these lesions and to achieve a complete oncologic resection. Current robotic techniques exist to help the thoracic surgeon overcome these challenges. In this review, an update of the latest MIS approaches and nodule detection techniques will be given.

A Retrospective Study of Far Lateral Midline Microlumbar Discectomy in 20 Patients at a Single Center in Turkey.

BACKGROUND Microdiscectomy is a minimally-invasive surgical technique for treating far lateral lumbar disc herniation (FLLDH). This retrospective study from a single center in Turkey aimed to evaluate midlinelumbar discectomy in 20 patients with far lateral lumbar disc herniation. MATERIAL AND METHODS We collected clinical data of 20 patients (11 men, 9 women) operated for FLDDH between January 2006 and January 2022. Patients' age, sex, surgical level, examination findings, motor deficit, duration of operation, complications during the operation and preoperative/postoperative 6 month visual analogue Scala (VAS), preoperative/postoperative 6th month Oswestry Disability Index (ODI) scores were evaluated. RESULTS The patients were 11 men (55%) and 9 women (45%), with a mean age of 52.08±11.21 years. The mean duration of symptoms before the operation was 3.4 weeks. Laseque sign positivity was found in 86.4% of the patients. Motor deficit was present in 30% of the patients. After 6-month follow-up, preoperative VAS value decreased from 9.35±0.75 to 0.84±0.75. Preoperative and postoperative VAS score averages were significantly different (P=0.0001). Operation ODI values were 73.63±3.76 before and after surgery, and decreased to 14.81±3.63 at 6 months. CONCLUSIONS The term distal lateral disc herniation was first defined in the literature in 1974 when the disc was seen in a different location than the normal location compared to the facet. Far lateral disc herniation can be operated on successfully with midline skin incision.

Ejaculation physiology and dysfunction after BPH surgery: the role of the new MISTs.

Human ejaculation can be defined as a complex and still largely unknown function. Since decades, Benign Prostatic Hyperplasia (BPH) surgery-associated loss of antegrade ejaculation has been reported as a bother by many patients. New technologies and modified surgical techniques were developed, to reduce the impact of ejaculatory dysfunction on patients' perceived quality of life. Recently, the emerging of the new Minimally Invasive Surgical Techniques (MISTs) empowered the urological surgeons with the technological means to introduce the ejaculation-sparing principles into everyday clinical practice. Our paper was conceived as a state-of-the-art analysis about the anatomical and physiological premises of the human ejaculation and their clinical application in the field of ejaculation-sparing surgery for the treatment of Lower Urinary Tract Symptoms (LUTS). Moreover, we proposed an innovative physiological model for antegrade ejaculation. We analysed the elements of the "ejaculatory apparatus" from an anatomical point of view. We investigated the physio-pathological models of the human ejaculation, from the classical "combustion chamber" paradigm to the new evidences by which it could be overcome. Finally, we provided a synthetic literature review about the ejaculation-sparing techniques for BPH surgery. Particularly, we distinguished them between classical techniques, modified for ejaculation-preserving purposes, and the new MISTs, characterized by the introduction of new technologies and different treatment modalities. Modified surgical techniques and new technologies opened new perspectives about human ejaculation. Previously established functional paradigms were questioned and overcome by recent clinical evidence. The new MISTs gained a prominent role in the process, opening a whole new era for BPH surgery.

Thymectomy in myasthenia gravis.

Thymectomy has long been used in the treatment of patients with myasthenia gravis and antibodies against the acetylcholine receptor. However, its effectiveness has only been proven a few years ago in a randomized controlled trial in patients under the age of 65. Here, we review the current literature focusing on patient subgroups, potential biomarkers for outcome prediction and the choice of surgical approach. Long-term follow-up studies after thymectomy confirmed that the benefits regarding clinical outcome parameters and a reduced need for immunosuppressive treatment persist. Nevertheless, a substantial proportion of patients in real-world cohorts do not reach complete stable remission after thymectomy indicating that the underlying autoimmune process is sustained in the periphery. Our understanding of the responsible mechanisms has improved with recent studies. Presently, outcome data after thymectomy in several patient subgroups, such as those aged over 50 years, those with juvenile onset or those with purely ocular symptoms are limited and have been the focus of recent research activities. Similarly, biomarkers guiding an appropriate patient selection for thymectomy are under investigation. A number of cohort studies demonstrated that minimal invasive surgical techniques such as extended robotic thymectomy lead to similar positive outcomes as a transsternal approach with potentially fewer short-term adverse effects. Thymectomy is an effective treatment option in adult patients with early onset acetylcholine-receptor positive myasthenia gravis but uncertainty remains with regard to certain patient subgroups.

Robotic mitral valve repair surgery: where do we go from here?

Surgical mitral valve repair through median sternotomy has long presented the treatment of choice for degenerative mitral valve disease. In recent decades, minimal invasive surgical techniques have been developed and are now gaining widespread popularity. Robotic cardiac surgery presents an emerging field, initially adopted only by selected centres, mostly in the United States. In recent years, the number of centers interested in robotic mitral valve surgery has grown with an increasing adoption in Europe as well. Increasing interest and surgical experience gained are stimulating further developments in the field and the full potential of robotic mitral valve surgery remains to be developed.

Minimally Invasive Surgical Technique through a Natural Anatomical Corridor for C1-C2 Screw Fixation

Objective: The atlantoaxial complex exhibits unique morphological and biomechanical characteristics. Trauma, tumors, and inflammatory or congenital diseases may compromise the stability of this joint. The purpose of this study was to describe a minimally invasive surgical (MIS) technique for C1-C2 fixation through an anatomical corridor and to analyze the clinical, surgical, and fusion outcomes using this approach over a 15-year period.Methods: We present a MIS technique utilizing a natural anatomical corridor for C1-C2 screw fixation, which has been used at our institution since 2007. We analyzed the demographic characteristics and clinical results of the patients who underwent this procedure.Results: Forty-seven patients underwent C1-C2 MIS screw fixation during the study period, with 24 male patients and a median age of 66 years. The indication for surgery was atlantoaxial subluxation in 60% of cases and odontoid fracture in 23%. The median surgery duration was 130 minutes, with a median blood loss of 300 mL. There were no intraoperative complications, and only one patient presented with a superficial wound infection, which was successfully treated with antibiotics.Conclusion: The minimally invasive approach through a natural anatomical corridor to fuse the atlantoaxial joint using C1 lateral masses and C2 pedicle screws bilaterally has been demonstrated to be safe and effective. Preserving the occipital-cervical tension band provides additional biomechanical stability to the construct.

To further enhance the minimal invasiveness of RT, we sought to evaluate potential advantages and feasibility of pure local transurethral intraprostatic anesthesia (TUIA) via the Schelin CatheterTM (ProstaLund AB, Lund, Sweden) (SC), a 3 ways device designed with an operational channel equipped with a retractile needle and the standard drainage and ballon ports (Figure 1). METHODS: After Ethical Commitee approval, included and collected data from 20 patients with moderate LUTS due to BPO, undergone RT procedure using TUIA by SC, from 2 centers. To rate their pain, patients were asked to use a numeric rating scale (NSR; numbered 0–10; 0 “No pain”/10 “Worst pain”) at 9-time points: 1-Preoperatively; 2-Schelin catheter insertion; 3-anestethic infiltration; 4-Rezum probe insertion; 5-Water Vapor Treatment (WVT); 6-Catheter insertion; 7-Day 1; 8-Day 7 catheter removal; 9-Day 30 follow-up visit. RESULTS: All 20 patients safely received TUIA prior RT. None required further anesthesiologic treatment. Median prostate size, Qmax, IPSS and QoL were 7 5ml, 9 mL/sec, 23 and 4, respectively. Median TUIA time was 3 minutes. Median catheterization time was 7 days. No need of re-catheterization or urinary tract infections at 30 days post-operatively were reported. Median NRS reported was 1.5 at each time point except at point 1, 2, 3 and 5. At preoperative stage NRS of pain was 0 in all cases. During catheter insertion (point 2) median NRS of pain was 2; during LA infiltration (point 3) was 2.5, and during WVT was 2 (point 5). One out of 10 patients reported a NRS of 6 during WVT (point 5). No perioperative anesthesiologic and procedure-related complications were recorded. CONCLUSIONS: Our data report for the first time in literature the feasibility and safeness of TUIA during RT using SC that showed full operative and post-operative pain control and reduced operative time and patient discomfort.

Laparoscopic drainage of large liver abscess, postoperative course, safety and efficacy

Background: In the era of minimal invasive surgical techniques, laparoscopic drainage provides faster recovery, shorter hospital stay, less surgical site infection and better cosmesis than open surgical drainage does with added advantage of accurate positioning of drainage catheter and simultaneous treatment of the abscess and underlying abdominal pathology. Methods: A total of 33 patients of age group 18-65 years were enrolled. Diagnosis was made using ultrasonography and CECT abdomen and laparoscopic drainage done and drain placed. Adequacy of drainage of abscess was analyzed using ultrasonography on POD- 5, 20 and 30 and were followed upto 3 months. Day of intra-cavitary drain removal, duration of post operative hospital stay, complications after surgery, requirement of readmission and intervention after readmission were recorded and analyzed. Results: Out of 33 patients, 1 patient developed sinus tract formation at intracavitary drain site. 3 patients had inadequate drainage for which drain change was required. 33% (N=11) patients showed complete resolution of abscess at post operative day 20 where as 72.7% patients (N=24) showed complete resolution of abscess on post operative day 30. All 33 patients showed complete resolution of abscess after 3 months of surgery. Conclusions: Laparoscopic procedure provides every advantages of open surgical drainage of liver abscess while avoiding complications of open surgeries. It allows breakdown of loculations, drainage of viscid pus, necrotic tissues, adequate irrigation of abscess cavity and should be considered for patients with large, complex, septated or multiple abscesses and failed percutaneous drainage.

Single incision laparoscopic right hemicolectomy: incisional hernia rate and postoperative pain management

Background: Single incision laparoscopic surgery (SILS) is a relatively new minimal invasive surgical technique for abdominal surgery compared to the multiport laparoscopic surgery. It has shown to have cosmetic advantages and has the potential to reduce postoperative pain and length of hospital stay. However, a drawback of SILS appears to be a higher incisional hernia rate. It is still unclear whether this rate is related to a larger incisional length or location of the incision. The aim of this study was to determine whether right hemicolectomy performed with SILS affected the postoperative incisional hernia rate.

Minimally invasive Vs open medial displacement calcaneal osteotomy. A cadaveric study

Category: Hindfoot; Hindfoot Introduction/ Purpose: Medial displacement calcaneal osteotomy (MDCO) is routinely used to correct hindfoot valgus in flexible pes planovalgus deformities. Classically MDCO was described through a lateral heel oblique incision with soft tissue dissection and the use of sagittal saw. Recently, minimally invasive surgical (MIS) techniques have gained popularity among foot and ankle surgeons, with the aim to reduce wound complications and postoperative pain and swelling. MIS calcaneal osteotomy was reported to be safe and effective as compared to open techniques. The aim of this cadaveric study was to compare the degree of deformity correction (coronal calcaneal displacement) using MIS vs open MDCO. Methods: Eight matched pairs foot and ankle cadaveric specimen were used. All specimens were checked radiographically for any previous foot and ankle operations or deformities. For each pair, one foot (right or left) was randomly assigned to either open or MIS MDCO. After the completion of osteotomy, the calcaneal tuberosity was maximally displaced medially and fixed with 2 mm wire. The displacement was measured manually using a flexible metric ruler. All osteotomies and manual measurement was done by the same Orthopaedic surgeon. Displacement was measured on standardized axial calcaneal radiographs by three blinded foot and ankle Orthopaedic surgeons independently using an image processing software with standard scaling for magnification. The displacement was measured laterally on the anterior body fragment and medially on the posterior tuberosity fragment Figures 1. Data was compared using the Wilcoxon-Mann-Whitney U test with the P value of &lt; 0.05 considered significant. Results: Five right and three left ankles underwent MIS osteotomy. On manual measurement the mean medial displacement was 7.87 mm and 8.66 mm for MIS and open technique respectively P=0.21). On radiographs, on medial measurements the average displacement of MIS osteotomy was 5.83 mm compared to 6.36 mm for the open group with a P value of 0.34. On lateral measurements the average displacement of MIS osteotomy was 5.94 mm compared to 6.17 mm for the open group with a P value of 0.67. Conclusion: This cadaveric study reported comparable coronal displacement using MIS vs open techniques for medical displacement calcaneal osteotomy. MIS calcaneal osteotomy offers a reliable alternative to open techniques with the potential advantages of lower wound related complications.

Prostatic artery embolization compared to transurethral resection of the prostate and prostatic urethral lift: a real-world population-based study.

There are growing interests for minimally invasive surgical techniques (MISTs) for the treatment of benign prostatic hyperplasia (BPH)-associated lower urinary tract symptoms (LUTS). Prostatic artery embolization (PAE) uses selective angioembolization of prostatic arteries, thereby reducing size to improve LUTS/BPH. However, real-world data comparing surgical outcomes between MISTs and tissue resective techniques are lacking. We assessed the differences in surgical outcomes between PAE, transurethral resection of the prostate (TURP), and prostatic urethral lift (PUL) in a real-world population for LUTS/BPH. We present an observational population-based study of 12,902 men with BPH in New York State who received PAE, TURP, and PUL in outpatient and ambulatory surgery settings from 2014 to 2018. For short-term outcomes, we report 30-day and 90-day risks of readmission to inpatient and emergency room (ER) with/without complications and compared them across groups using χ2 tests and mixed-effect logistic regressions. For long-term outcomes, we report surgical retreatment and stricture rates using Kaplan-Meier failure curves and compared them using Log rank tests and Cox regression models. Of 12 902 men, 335 had PAE, 11,205 had TURP, and 1362 had PUL. PAE patients had the highest 30-day (19.9%) and 90-day (35.6%) risks of readmission to inpatient or ER (p < 0.01). Non-specific abdominal pain was the main diagnosis associated with 30-day and 90-day readmissions to inpatient or ER after PAE (14.3% and 26.8%, respectively). After 2years of follow-up, PAE patients had the highest retreatment rate of 28.5% (95%CI 23.7-34.2%) compared to TURP (3.4% (95%CI 3.1-3.8%)) and PUL (8.5% (95%CI 5.6-12.9%)) (p < 0.001). In a real-world population, PAE was associated with the most frequent 30-day and 90-day readmission to inpatient or ER and the highest retreatment rate among all surgical techniques even when controlled for individual patient comorbidities and surgical volume.
