Novel axillary approach for brachial plexus in robotic surgery: a cadaveric experiment.
Minimally invasive surgery 20140721
Brachial plexus surgery using the da Vinci surgical robot is a new procedure. Although the supraclavicular approach is a well known described and used procedure for robotic surgery, axillary approach was unknown for brachial plexus surgery. A cadaveric study was planned to evaluate the robotic axillary approach for brachial plexus surgery. Our results showed that robotic surgery is a very useful method and should be used routinely for brachial plexus surgery and particularly for thoracic outlet ...[more]

Project description:Axillary plexus blocks are usually guided by ultrasound, but alternative methods may be used when ultrasound equipment is lacking. For a nonultrasound-guided axillary block, the need for three injections has been questioned.Could differences in block success between single, double and triple deposits methods be explained by differences in local anaesthetic distribution as observed by MRI?A blinded and randomised controlled study.Conducted at Oslo University Hospital, Rikshospitalet, Norway from 2009 to 2011.Forty-five ASA 1 to 2 patients scheduled for surgery were randomised to three equally sized groups. All patients completed the study.Patients in the single-deposit group had an injection through a catheter parallel to the median nerve. In the double-deposit group the patients received a transarterial block. In the triple-deposit group the injections of the two other groups were combined. Upon completion of local anaesthetic injection the patients were scanned by MRI, before clinical block assessment. The distribution of local anaesthetic was scored by its closeness to terminal nerves and cords of the brachial plexus, as seen by MRI. The clinical effect was scored by the degree of sensory block in terminal nerve innervation areas.Sensory block effect and MRI distribution pattern.The triple-deposit method had a higher success rate (100%) than the single-deposit method (67%) and the double-deposit method (67%) in blocking all cutaneous nerves distal to the elbow (P?=?0.04). The patients in the triple-deposit group most often had the best MRI scores. For any nerve or cord, at least one of the single-deposit or double-deposit groups had a similarly high MRI score as the triple-deposit group.Distal to the elbow, the triple-deposit method had the highest sensory block success rate. This could be explained to some extent by analysis of the magnetic resonance images.ClinicalTrials.gov identifier: NCT01033006.

Project description:Background. Distal arm surgery is widely performed under regional anesthesia with brachial plexus block. The preponderance of evidence for the efficacy relies upon injection of local anesthetic in excess of 30?mL. We aimed to compare three different ultrasound-guided brachial plexus block techniques restricting the total volume to 20?mL. Methods. 120 patients were prospectively randomized to ultrasound-guided brachial plexus block with 20?mL ropivacaine 0.75% at either the supraclavicular, infraclavicular, or axillary level. Multiinjection technique was performed with all three approaches. Primary outcome measure was performance time. Results. Performance time and procedural pain were similar between groups. Needle passes and injection numbers were significantly reduced in the infraclavicular group (P < 0.01). Nerve visibility was significantly reduced in the axillary group (P = 0.01). Success-rate was significantly increased in the supraclavicular versus the axillary group (P < 0.025). Total anesthesia-related time was significantly reduced in the supraclavicular compared to the infraclavicular group (P < 0.01). Block duration was significantly increased in the infraclavicular group (P < 0.05). No early adverse effects occurred. Conclusion. Supraclavicular and infraclavicular blocks exhibited favorable characteristics compared to the axillary block. Supraclavicular brachial plexus block with the multiinjection intracluster technique exhibited significantly reduced total anesthesia-related time and higher success rate without any early adverse events.

Project description:A 64-year-old male patient underwent cardiac resynchronization therapy (CRT) device implantation via the axillary venous approach. Two weeks later, the patient started complaining of "electric shock-like" pain in the left axillary area. During physical examination, typical pain in the left axillary area was reproduced whenever his left shoulder was passively abducted more than 60 degrees. Fluoroscopic examination showed that the left ventricle (LV) and right atrium (RA) leads were positioned at an acute angle directing towards the left brachial plexus whenever the patient's shoulder was passively abducted. Brachial plexus irritation by the angulated CRT leads was strongly suspected. To relieve the acute angulation, we had to adjust the entry site of the LV and RA leads from the distal to the proximal axillary vein using the cut-down method. After successful lead repositioning, the neuropathic pain improved rapidly. Although transvenous pacing lead-induced nerve injury is not a frequent complication, this possibility should be kept in mind by the operators.

Project description:Interscalene brachial plexus block (ISBPB) provides optimal analgesia for shoulder surgery. However, several limitations still exist, including the short duration of analgesia, rebound pain, a high incidence of unilateral diaphragmatic paresis, and potential risk of nerve damage, prompting the search for alternative techniques. Many alternatives to ISBPB have been studied to alleviate these concerns, and clinicians should choose an appropriate option based on the patient's condition. In this mini-review, we aimed to present recent updates on ISBPB while discussing our clinical experiences in shoulder surgery.

Project description:Breast cancer is the most prevalent cancer and second leading cause of cancer-related deaths in both the US and UK female population, a prominent cause of morbidity and cost to both health services. All surgically fit patients are offered breast reconstruction following the initial surgery, and this is traditionally an open approach: either implant-based or an autologous tissue flap. Both lead to scarring that is difficult to conceal. This paper aims to evaluate the novel minimally invasive technique of robotic-assisted surgery. Methods:A systematic review was conducted using Medline (OvidSP) and Embase (OvidSP) to evaluate the current application of robotic-assisted surgery in breast surgery and reconstruction. Results:Twenty-one articles were identified and discussed, composing of level 4 and 5 evidence comparing different surgeons' experiences, techniques, and outcomes. To date, the robotic system has been utilized to harvest the latissimus dorsi muscle for use as a tissue flap (total harvest time of 92 minutes), to perform nipple-sparing mastectomy with immediate breast reconstruction (total operation time 85 minutes) and lately to harvest a deep inferior epigastric perforator flap via an intraabdominal approach. Conclusions:Robotic-assisted surgery can successfully and reproducibly perform a nipple-sparing mastectomy with breast reconstruction. It can minimize the size of scarring and is superior to the laparoscopic technique, with improved 3-dimensional visualization, dexterity, and range of motion able to guide around the curvature of the breast. The main limiting factors are the lack of the US Food and Drug Administration approval, cost of the robot, and specialized skills required.

Project description:Background and purposeBrachial plexus birth injury is caused by traction on the neck during delivery and results in flaccid palsy of an upper extremity commonly involving C5-C6 nerve roots. MR imaging and MR myelography help to assess the anatomic location, extent, and severity of brachial plexus injuries which influence the long-term prognosis along with the surgical decision making. Recently, sonography has been increasingly used as the imaging modality of choice for brachial plexus injuries. The aim of this study was to assess the degree of correlation among brachial plexus sonography, MR imaging, and surgical findings in children with brachial plexus birth injury.Materials and methodsThis prospective study included 55 consecutive patients (girls/boys = 32:23; mean age, 2.1 ± 0.8 months) with brachial plexus birth injury between May 2014 and April 2017. The patients were classified according to the Narakas classification and were followed up at 4- to 6-week intervals for recovery by the Modified Mallet system and sonography without specific preparation for evaluation. All patients had MR imaging under general anesthesia. Nerve root avulsion-retraction, pseudomeningocele, and periscalene soft tissue were accepted brachial plexus injury findings on imaging. Interobserver agreement for MR imaging and the agreement between imaging and surgical findings were estimated using the κ statistic. The diagnostic accuracy of sonography and MR imaging was calculated on the basis of the standard reference, which was the surgical findings.ResultsForty-three patients had pre- and postganglionic injury, 12 had only postganglionic injury findings, and 47% of patients underwent an operation. On sonography, no patients had preganglionic injury, but all patients had postganglionic injury findings. For postganglionic injury, the concordance rates between imaging and the surgical findings ranged from 84% to 100%, and the diagnostic accuracy of sonography and MR imaging was 89% and 100%, respectively. For preganglionic injury, the diagnostic accuracy of MR imaging was 92%. Interobserver agreement and the agreement between imaging and the surgical findings were almost perfect for postganglionic injury (κ = 0.81-1, P < .001).ConclusionsHigh-resolution sonography can identify and locate the postganglionic injury associated with the upper and middle trunks. The ability of sonography to evaluate pre- and the postganglionic injury associated with the lower trunk was quite limited. Sonography can be used as a complement to MR imaging; thus, the duration of the MR imaging examination and the need for sedation can be reduced by sonography.

Project description:OBJECTIVE:We hypothesized that ultrasound (US)-guided technique of the supra- and infraclavicular and axillary approaches of brachial plexus block (BPB) will produce a high quality of surgical anesthesia for operations below the shoulder independently of the approach and body mass index (BMI). Intercostobrachial and medial brachial cutaneous nerves will be blocked separately because they are not a part of the brachial plexus. METHODS:This is a prospective randomized observer-blinded study. The three approaches of the US-guided BPB without neurostimulation were compared for quality, performance time, and correlation between performance time and BMI. Intercostobrachial and medial brachial cutaneous nerve blocks were used in all patients. RESULTS:A total of 101 patients were randomized into three groups: SCL (supraclavicular), ICL (infraclavicular), and AX (axillary). Seven patients were excluded due to various factors. All three groups were similar in demographic data, M:F proportion, preoperative diagnosis and type of surgery, anesthesiologists who performed the block, and surgical staff that performed the surgical intervention. The time between the end of the block performance and the start of the operation was also similar. The quality of the surgical anesthesia and discomfort during the operation were identical following comparison between groups. No direct positive correlation was observed between BMI and the block performance time. The time for the axillary block was slightly longer than the time for the supra- and infraclavicular approaches, but it had no practical clinical significance. Transient Horner syndrome was observed in three patients in the SCL group. No other adverse effects or complications were observed. CONCLUSIONS:All three approaches can be used for US-guided BPB with similar quality of surgical anesthesia for operations of below the shoulder. A block of the intercostobrachial and medial brachial cutaneous nerves is recommended. Obesity is not a significant factor in relation to the time of US-guided BPB performance, or the quality of surgical anesthesia. (ClinicalTrials.gov number, NCT01442558.).

Project description:New developments in the surgery of the brachial plexus include the use of less invasive surgical approaches and more precise techniques. The theoretical advantages of the use of robotics versus endoscopy are the disappearance of physiological tremor, three-dimensional vision, high definition, magnification, and superior ergonomics. On a fresh cadaver, a dissection space was created and maintained by insufflation of CO2. The supraclavicular brachial plexus was dissected using the da Vinci robot (Intuitive Surgical, Sunnyvale, CA). A segment of the C5 nerve root was grafted robotically. A series of eight clinical cases of nerve damage around the shoulder girdle were operated on using the da Vinci robot. The ability to perform successful microneural repair was confirmed in both the authors' clinical and experimental studies, but the entire potential of robotically assisted microneural surgery was not realized during these initial cases because an open incision was still required. Robotic-assisted surgery of the shoulder girdle and brachial plexus is still in its early stages. It would be ideal to have even finer and more suitable instruments to apply fibrin glue or electrostimulation in nerve surgery. Nevertheless, the prospects of minimally invasive techniques would allow acute and subacute surgical approach of traumatic brachial plexus palsy safely, without significant and cicatricial morbidity.

Project description:Background:Harmonic ACE® (Harmonic) Curved Shears are frequently used for vessel sealing in patients undergoing robotic thyroidectomy. Unlike other robotic devices with articulation, the Harmonic device can only move in a straight-forward direction without articulation. The recently introduced Vessel Sealer Extend® (VSE) provides bipolar sealing and cutting with articulation movement. This study compared the VSE and Harmonic devices in robotic bilateral axillary-breast approach (BABA) thyroid surgery. Methods:From December 2018 to March 2019, 35 consecutive patients underwent robotic BABA thyroidectomy, 20 using the VSE and 15 using the Harmonic device. Patient characteristics, pathologic results, and clinical outcomes, including complications, were evaluated. Results:The characteristics of patients in the two groups were similar. Surgical time from robot docking to completion of lobectomy was longer in the VSE than in the Harmonic group (45.00±9.52 vs. 39.72±12.76 min; P=0.170). The number of camera cleanings during lobectomy was significantly lower in the VSE group (0.55±0.51 vs. 1.93±1.71; P=0.002). Intraoperative blood loss (53.00±43.29 vs. 28.67±41.03 mL; P=0.102), hospital stay after surgery (3.55±0.95 vs. 3.67±0.90 days; P=0.715), and pain scores on the first (2.85±0.37 vs. 2.93±0.26; P=0.458) and second (2.55±0.51 vs. 2.60±0.51; P=0.775) postoperative days were similar in the VSE and Harmonic groups. No patient experienced vocal cord palsy or postoperative bleeding. Conclusions:VSE can be safely applied to robotic BABA thyroid surgery.

Project description:Adult traumatic brachial plexus injuries can have devastating effects on upper extremity function. Although neurolysis, nerve repair, and nerve grafting have been used to treat injuries to the plexus, nerve transfer makes use of an undamaged nerve to supply motor input over a relatively short distance to reinnervate a denervated muscle. A review of several recent innovations in nerve transfer surgery for brachial plexus injuries is illustrated with surgical cases performed at this institution.
