Endoscopic Resection of the Tarsal Tunnel Ganglion.

ABSTRACT: The tarsal tunnel ganglion is a cause of posterior tarsal tunnel syndrome. Open resection of the ganglion calls for release of the flexor retinaculum and dissection around the tibial neurovascular bundle. This can induce fibrosis around the tibial nerve. We report the technique of endoscopic resection of the tarsal tunnel ganglion. It is indicated for tarsal tunnel ganglia arising from the adjacent joints or tendon sheaths and compressing the tibial nerve from its deep side. It is contraindicated if there is other pathology of the tarsal tunnel that demands open surgery; if the ganglion compresses the tibial nerve from its superficial side, which calls for a different endoscopic approach using the ganglion portal; or if an intraneural ganglion of the tibial nerve is present. The purpose of this technical note is to describe a minimally invasive approach for endoscopic resection of the tarsal tunnel ganglion.

Endoscopic Ganglionectomy of the Tarsal Tunnel: A Medial Approach.

Project description:A ganglion inside the tarsal tunnel can compress the tibial nerve, leading to posterior tarsal tunnel syndrome. Classically, the ganglion is resected with an open approach. This requires release of the flexor retinaculum and dissection around the tibial neurovascular bundle, which may induce fibrosis around the tibial nerve. Endoscopic resection of a tarsal tunnel ganglion via a posterior approach has been reported. The purpose of this Technical Note is to describe the medial approach of endoscopic ganglionectomy of the tarsal tunnel. This is indicated for tarsal tunnel ganglia compressing the tibial nerve and extending to the flexor retinaculum. It is contraindicated if there is other pathology of the tarsal tunnel that demands open surgery; the ganglion compresses the tibial nerve from its deep side and does not extend to the flexor retinaculum; or in the presence of intraneural ganglion of the tibial nerve.

ASGE guideline for endoscopic full-thickness resection and submucosal tunnel endoscopic resection.

Project description:With the development of reliable endoscopic closure techniques and tools, endoscopic full-thickness resection (EFTR) is emerging as a therapeutic option for the treatment of subepithelial tumors and epithelial neoplasia with significant fibrosis. EFTR may be categorized as "exposed" and "nonexposed." In exposed EFTR, the full-thickness resection is undertaken with a tunneled or nontunneled technique, with subsequent closure of the defect. In nonexposed EFTR, a secure serosa-to-serosa apposition is achieved before full-thickness resection of the isolated lesion. This document reviews current techniques and devices used for EFTR and reviews clinical applications and outcomes.

Endoscopic Resection of Horseshoe Ganglion of the Lateral Midfoot.

Project description:A ganglion is the most common soft-tissue mass in the foot and can cause pain, paresthesia, or footwear problems. A ganglion can extend from the dorsum into the plantar compartment of the foot in the form of a horseshoe at the borders of the foot or in the form of an hourglass through the intermetatarsal space. Initial conservative management of a ganglion may entail observation and the use of padding for comfort, manual rupture, aspiration of the cyst contents, and steroid injection or sclerotherapy into the cyst. When the lesion is recurrent or painful, surgical excision is recommended. The purpose of this Technical Note is to describe the details of endoscopic resection of a horseshoe ganglion of the lateral midfoot. This technique has the advantages of being minimally invasive, with better cosmetic results and less surgical trauma to the soft tissue.

Endoscopic Stalk Resection of a Toe Ganglion With Color-aided Visualization.

Project description:Ganglion cysts are common cystic lesions filled with a jelly-like substance and originate from a joint capsule or tendon sheath through a stalk. Ganglion cysts mostly occur in the hand region, for which surgical excision usually results in good outcomes. In contrast, toe ganglions are relatively rare, and surgical treatment is associated with a high recurrence rate because of unidentifiable ganglion stalks, requiring large skin incisions. We have treated toe ganglion cysts using endoscopy in the ganglion cyst by injecting methylene blue into the tendon sheath that connects to the ganglion stalk. The result has been favorable, without recurrence. The advantages of our technique include the following: (1) Endoscopy using a color aid can show the location of a ganglion stalk, and removing the stalk can prevent recurrence. (2) Endoscopic stalk-only resection is minimally invasive, allowing early mobilization and reducing surgical-site complications. The purpose of this Technical Note is to describe our endoscopic stalk resection technique with color-aided visualization, and we have included a video presentation.

Effect of Lateral Sliding Calcaneus Osteotomy on Tarsal Tunnel Pressure.

Project description:BackgroundLateral sliding calcaneus osteotomies are common procedures to correct hindfoot varus deformities. Shifting the calcaneal tuberosity laterally (lateralization) can lead to tarsal tunnel pressure increase and tibial nerve palsy. The purpose of this cadaveric biomechanical study was to investigate the correlation of lateralization and pressure increase underneath the flexor retinaculum.MethodsThe pressure in the tarsal tunnel of 12 Thiel-fixated human cadaveric lower legs was measured in different foot positions and varying degrees of calcaneal lateralization.ResultsThe mean pressure increased from plantarflexion (PF) to neutral position (NP) and from NP to hindfoot dorsiflexion (DF), and with increasing amounts of lateralization of the calcaneal tuberosity. The mean baseline pressure in PF was 1.5, in NP 2.2, and in DF 6.5 mmHg and increased to 8.1 in PF, 18.4 in NP, and 33.1 mmHg with 12 mm of lateralization. The release of the flexor retinaculum significantly lowered the pressure.ConclusionIncreasing pressures were found in the tarsal tunnel with increasing lateralization of the tuberosity and with both dorsiflexion and plantarflexion of the ankle.Clinical relevanceA pre-emptive release of the flexor retinaculum for a lateralization of the calcaneal tuberosity of more than 8 mm should be considered, especially if specific patient risk factors are present. No tibial nerve palsy should be expected with 4 mm of lateralization.

Tarsal tunnel release restores sensations in sole for diabetic sensorimotor polyneuropathy.

Project description:BackgroundDiabetic sensorimotor polyneuropathy (DSPN) is the commonest form of neuropathy. Loss of sensations in sole leads to diabetic foot ulcers (DFU) and its complications. Surgical decompression has been used in the treatment of diabetic peripheral neuropathy, however; its effectiveness has been questioned.Purpose of this study was to evaluate the sensory recovery in sole after tarsal tunnel decompression (TTD) in patients having DSPN.MethodsThirteen patients (Age28-70 years, average 35.57 years; 7 Males, 6 Females; 20 feet) with DSPN and positive Tinel's sign over the tarsal tunnel were included in the study. Pre and post-operative sensory tests performed on the sole included tests for touch, pain, temperature, pressure, vibration perception threshold (VPT) and two-point discrimination (2-PD). Results were classified as per British Medical Research Council (MRC) scoring system.Results-Sixteen feet were followed-up for 6 months. In all feet perception of touch, pain and pressure recovered. Temperature perception recovered in 75% feet. VPT came to normal range (16.81V) from 40.37 V and 2-PD came down to average of 6.0 mm from preoperative average of11.2 mm.MRC scale improved from S0 in 5 feet and S2 in 15 feet to S3+ in all 16 feet.There were no ulcers or amputation in operated limbs during follow up period of 6 months.ConclusionsTTD improves plantar sensations in diabetic neuropathy and prevents ulcers and its related complications.

A case of endoscopic full‐thickness resection for gastric gastrointestinal stromal tumor in the submucosal tunnel

Project description:Abstract The patient was a 49‐year‐old female with a submucosal tumor (12×12 mm) located in the lesser curvature side of the stomach. The diagnosis by endoscopic ultrasound fine‐needle aspiration was of a gastrointestinal stromal tumor. Computed tomography and endoscopic ultrasound showed gastrointestinal stromal tumor with an intra‐luminal growth type. Endoscopic full‐thickness resection was then performed. To achieve good counter traction, enough safety margin, and minimal defect of muscle, full‐thickness resection via creating a submucosal tunnel was performed as a new technique. The final histological diagnosis was gastrointestinal stromal tumor with R0 resection.

Ultrasound-Assisted Endoscopic Carpal Tunnel Release.

Project description:Various surgical procedures for carpal tunnel syndrome exist, such as open release, ultrasound-guided percutaneous release, and endoscopic release. Postoperative pain, scarring, and slow recovery to normal function are reported complications of open release. Damage to vessels and the median nerve and its branches underlying the transverse carpal ligament is a reported complication of ultrasound-guided percutaneous release. Damage to the superficial palmar arch and incomplete release are reported complications of endoscopic release. By performing endoscopic carpal tunnel release with ultrasound assistance, we could visualize neurovascular structures directly with the endoscope and also indirectly with ultrasound to minimize complications. We could also evaluate the morphologic changes of the median nerve dynamically before and after the release. We discuss the technique for this procedure and outline pearls and pitfalls for success.

Ultrasonography Findings of the Carpal Tunnel after Endoscopic Carpal Tunnel Release for Carpal Tunnel Syndrome.

Project description:ObjectiveTo investigate changes in the median nerve, retinaculum, and carpal tunnel on ultrasound after successful endoscopic carpal tunnel release (ECTR).Materials and methodsThis prospective study involved 37 wrists in 35 patients (5 male, 30 female; mean age ± standard deviation [SD], 56.9 ± 6.7 years) with primary carpal tunnel syndrome (CTS). An in-house developed scoring system (0-3) was used to gauge the clinical improvement after ECTR. Ultrasound was performed before ECTR, and at 1, 3, and 12 months post-ECTR. Changes in the median nerve, flexor retinaculum, and carpal tunnel morphology on ultrasound after ECTR were analyzed. Ultrasound parameters for different clinical improvement groups were compared.ResultsAll patients improved clinically after ECTR. The average clinical improvement score ± SD at 12 months post-ECTR was 2.2 ± 0.7. The median nerve cross-sectional area proximal and distal to the tunnel decreased at all time intervals post-ECTR but remained swollen compared to normal values. Serial changes in the median nerve caliber and retinacular bowing after ECTR were more pronounced at the tunnel outlet than at the tunnel inlet. The flexor retinaculum had reformed in 25 (68%) of 37 wrists after 12 months.ConclusionPostoperative changes in median nerve and retinaculum parameters were most pronounced at the tunnel outlet. Even in patients with clinical improvement after ECTR, nearly all ultrasound parameters remain abnormal at one year post-ECTR. These ultrasound parameters should not necessarily be relied upon to diagnose persistent CTS after ECTR.

Tarsal tunnel syndrome in the mucopolysaccharidoses: A case series and literature review.

Project description:Background:The mucopolysaccharidoses (MPS) are a group of inherited, progressive, multi-system lysosomal storage disorders. Musculoskeletal manifestations include nerve entrapment syndromes, most commonly carpal tunnel syndrome. Tarsal tunnel syndrome (TTS) has also been reported. The purpose of this study was to investigate the clinical course of MPS patients with suspected TTS and to conduct a literature review of TTS in MPS. Methods:A review of the Medline and EMBASE databases was conducted in accordance with published guidelines from the Joanna Briggs Institute of Evidence Based Medicine with search strategy developed by a librarian trained in systematic reviews. A medical record review was undertaken for all patients managed in the multi-disciplinary MPS clinic in a tertiary referral paediatric centre, identifying patients with a suspected or established diagnosis of TTS. Data regarding the demographics, investigations, presentation, management, and clinical course were collected. Results:The literature review failed to identify any published papers regarding TTS in MPS, with conference proceedings only identified. Within a cohort of 19 MPS patients, four patients with a suspected diagnosis of TTS were identified (MPS I: two patients, MPS VI: two patients). Three patients underwent surgical tarsal tunnel decompression, two with good result. One patient had overlapping symptoms with spinal stenosis and improvement in suspected tarsal tunnel symptoms following spinal decompression and fusion.
