TFRR is the most used surgical technique for treatment of TOS9,10,11. The advantage of the TFRR is that it provides a better cosmetic result with a hidden incision in the axilla without requirement of cutting the muscles to reach the surgical field. Its disadvantage is the relatively narrow and deep working space. The supraclavicular approach, which is preferred for arterial TOS treatment, puts the subclavian artery at less risk...

The compression of the brachial plexus, subclavian artery or vein in the scalene triangle is clinically known as thoracic outlet syndrome (TOS), first described by Peet et al.1. Thoracic outlet syndrome is subdivided into neurogenic (NTOS), arterial TOS, and venous TOS based on the underlying etiology1. Patients with NTOS (93-95% of TOS cases) present with pain, numbness, and ipsilateral weakness. Patients with venous TOS (3-5%) present with venous thrombosis, and patients with arterial TOS (1-2%) present with arterial thromboembolic event and ischemia. Conservative management of TOS includes medications and physiotherapy and is the first choice for TOS cases. The surgical treatment modalities include decompression procedures and are performed after conservative management has failed2. Decompression techniques include the transaxillary first rib resection (TFRR), supraclavicular first rib resection scalenectomy (SFRRS), scalenectomy (without first rib resection via supraclavicular or transaxillary), and posterior approach first rib resection (PA-FRR)3. The transaxillary first rib resection, a technique described by Roos et al. in 1966, is an effective method for treatment of TOS4,5. The main goal of TFRR is to completely remove the last cervical and first thoracic ribs and to decompress the underlying neurovascular bundle.
Vascular TOS (VTOS) are diagnosed with CT angiography, color duplex USG, and arteriography or venography, whereas the NTOS is diagnosed with X-ray, electrodiagnostic studies (needle electromyelography), color duplex Doppler USG, and cervical MRI. Physiotherapist and psychiatrist consultations should be obtained to exclude other disorders preoperatively.The symptom relief with lidocaine injection to the anterior scalene muscle is also a good indicator for diagnosis and predictor of surgical benefit in NTOS patients6.

transaxillary first rib resection for treatment of the thoracic outlet syndrome

Thoracic outlet syndrome (TOS) is a common disorder that causes a significant loss of productivity. The transaxillary first rib resection (TFRR) protocol has been used for the decompression of trapped neurovascular structures in the TOS. Among the other surgical procedures, the advantage of the TFRR is that it has the smallest rate of recurrence and better cosmetic outcomes. The disadvantage of TFRR is that it provides a narrow, and deep working corridor that makes obtaining vascular control challenging.

Clinical Outcomes 
A total of 15 patients were included in this study. Three patients (20%) were male and 12 of patients (80%) were female. The mean age of patients was 30.6 &#177; 8.98 years. All male participants and 5 of female participants were manual laborers. The most common complaint of the NTOS group was arm-forearm pain and numbness weakness of grip and hypothenar atrophy. In the postoperative clinical follow-up, patients were questioned about their paresthesia and pain severity, overall sa...

Transaxillary First Rib Resection for Treatment of the Thoracic Outlet Syndrome

Here, we present a protocol of the transaxillary resection of the first rib for treatment of thoracic outlet syndrome caused by compression of the brachial plexus, subclavian vein and artery.

This transaxillary first rib resection procedure can be used for the treatment of thoracic outlet syndrome caused by compression of brachial plexus, subclavian vein, and artery. The advantage of transaxillary first rib resection is that it has a smaller rate of recurrence and better cosmetic outcomes than standard treatment options. To perform an Adson test, bring the patient's shoulder to external rotation with slight abduction and a little bit of extension, and palpate the radial pulse.Extend the patient's head backward and rotate the head toward the tested shoulder. Ask the patient to breathe in and hold their breath. The test is considered positive when the reproduction of symptoms or the abolition of the radial pulse occurs and the symptoms resolve with rotation of the head to the contralateral side.For a costoclavicular brace test, bring the patient's arm to the back and depress and retract the arm over the patient's ipsilateral scapula. Check the radial pulse. If the pulse disappears or symptoms are reproduced, the test is considered positive.For the hyperabduction test, slightly extend the patient's arm and palpate the radial artery while abducting the arm 90 to 180 degrees. A positive test is indicated by a decrease in the pulse of the radial artery from baseline to the new position. For a Roos test, with the patient in either a sitting or standing position, move the patient's shoulders to 90-degree abduction and externally rotate and flex the elbows to 90 degrees.With the elbows slightly behind the frontal plane, have the patient open and close their hands for three minutes. The test is considered positive if the patient experiences heaviness, ischemic pain or weakness of the arms, or numbness and tingling of the hands. Discoloration of the hands is also meaningful for the test.For evaluation of the clinical improvement with surgical treatment, record the clinical findings from the physical examination and the QuickDASH questionnaire related to the symptoms of daily activities and social and psychological preoperative periods. To determine the preoperative electromyography values, use an appropriate commercial measuring system to measure the compound motor action potential, sensory nerve action potential, nerve conduction velocity, and F-wave latency according to standard protocols. For transaxillary first rib resection after confirming sedation, place the patient in the lateral decubitus position and wrap and elevate the arm in a 90-degree abduction position.Use a 10%sterile povidone-iodine solution for topical sterilization and drape the arm, axilla, and chest. Use sterile sheets on the rest of the body to prevent contamination. Make a five to seven-centimeter transverse incision below the axillary hairline, extending from the pectorals muscle anteriorly and the latissimus dorsi muscle posteriorly, and cross the skin's subcutaneous tissue and fascia to reach the anterior chest wall.With the aid of a focus scope, use blunt dissection to access the first rib and to pierce the overlying fascia. Dissect the pariosteal overlying the superior part of the rib and use monopolar cautery and rib raspatory to bluntly dissect the inferior edge of the rib from the surrounding muscles. Split the intercostal muscles until the costoclavicular ligament is at the sternocostal junction and the angular costa in the posterior costovertebral junction.In the superior edge of the first rib, expose the anterior scaling muscle anteriorly and the medial scalene muscle posteriorly. Place the curved forceps under the anterior and middle scalene muscle to cut the muscles at the level of their insertion over the first rib at the point farthest from the neurovascular bundle. Starting the resection of the first rib at the sternocostal junction anteriorly, turn a rib cutter blade from its superior edge into the inferior edge to resect the junction from the sternum, taking care that the neurovascular structures are preserved.To complete the resection, resect the posterior portion of the rib and disarticulate the region distal to the angle of the rib. After totally freeing the cervical rib from the surrounding tissue, resect and disarticulate the rib until the articular surface of the transverse process can be observed. After the procedure, perform a chest X-ray to rule out complications, such as pneumothorax.In uneventful cases, remove the thorax drain on postoperative day one. In the early postoperative period, examine movement of the arm and the treated side, and advise the patient to not perform any exhausting activity with the treated side. In this representative analysis, the most common complaint of the neurogenic thoracic outlet syndrome group was arm/forearm pain, numbness, and weakness of grip, and hypothenar atrophy.Electrodiagnostic outcomes and electromyography values were evaluated preoperatively and in the postoperative period is demonstrated, and a remarkable clinical improvement between pre-op and postoperative EMG values was observed. Take care to insert the curved forceps under the subclavian muscles to assure that the muscles are cut at the level of insertion over the first trip at the neurovascular bundle. Patients should continue physical therapy for the first two postoperative months for pain management and to decrease the risk of injury recurrence.

Isolated Hepatic Perfusion as a Treatment for Liver Metastases of Uveal Melanoma

Isolated hepatic perfusion (IHP) is a procedure where the liver is surgically isolated and perfused with a high concentration of the chemotherapeutic agent melphalan. Briefly, the procedure starts with the setup of a percutaneous veno-venous bypass from the femoral vein to the external jugular vein. Via a laparotomy, catheters are then inserted into the proper hepatic artery and the caval vein. The portal vein and the caval vein, both supra- and infrahepatically, are then clamped. The arterial and venous catheters are connected to a heart lung machine and the liver is perfused with melphalan (1 mg/kg body weight) for 60 min. This way it is possible to locally perfuse the liver with a high dose of a chemotherapeutic agent, without leakage to the systemic circulation.
In previous studies including patients with isolated liver metastases of uveal melanoma, an overall response rate of 33-100% and a median survival between 9 and 13 months, have been reported. The aim of this protocol is to give a clear description of how to perform the procedure and to discuss IHP as a treatment option for liver metastases of uveal melanoma.

Here, we present a protocol how to perform an isolated liver perfusion (IHP) with melphalan and we also discuss IHP as a treatment option for liver metastases of uveal melanoma.

Surgical Models of Gastroesophageal Reflux with Mice

Multiple surgical procedures have been reported to induce gastroesophageal reflux in animals. Herein, we report three surgical models with mice aiming to induce reflux of gastric contents, duodenal contents or mixed contents. Surgical procedures and general principles have been described in detail. A researcher with surgical experience should be able to grasp the technique after a short period of practice. After surgery, most mice can survive and develop reflux esophagitis similar to that in humans. However, it should be noted that histological differences between mouse and human esophagus are the inherent limitations of these surgical models. If used for research on Barrett&#8217;s esophagus and adenocarcinoma, these procedures may need to be combined with genetic modifications.

This article demonstrates surgical procedures of gastroesophageal reflux with mice. These models are useful tools for research on mechanisms and treatment of gastroesophageal reflux disease and potentially Barrett&#8217;s esophagus and esophageal adenocarcinoma.

Network Analysis of Foramen Ovale Electrode Recordings in Drug-resistant Temporal Lobe Epilepsy Patients

Approximately 30% of epilepsy patients are refractory to antiepileptic drugs. In these cases, surgery is the only alternative to eliminate/control seizures. However, a significant minority of patients continues to exhibit post-operative seizures, even in those cases in which the suspected source of seizures has been correctly localized and resected. The protocol presented here combines a clinical procedure routinely employed during the pre-operative evaluation of temporal lobe epilepsy (TLE) patients with a novel technique for network analysis. The method allows for the evaluation of the temporal evolution of mesial network parameters. The bilateral insertion of foramen ovale electrodes (FOE) into the ambient cistern simultaneously records electrocortical activity at several mesial areas in the temporal lobe. Furthermore, network methodology applied to the recorded time series tracks the temporal evolution of the mesial networks both interictally and during the seizures. In this way, the presented protocol offers a unique way to visualize and quantify measures that considers the relationships between several mesial areas instead of a single area.

This protocol describes a procedure to track the evolution of mesial network measures in temporal lobe epilepsy (TLE) patients. It is based on the combination of intracranial recordings with a novel numerical technique for data analysis. Specifically, we present a protocol for network analyses of foramen ovale recordings.

Laparoscopy-endoscopy Cooperative Surgery for the Treatment of Gastric Gastrointestinal Stromal Tumors

In view of the shortcomings of endoscopic or laparoscopic surgeries alone in the treatment of gastric gastrointestinal stromal tumors (G-GISTs), this approach makes an innovative improvement in the treatment of G-GISTs that are less than 5 cm in size. Laparoscopy-endoscopy cooperative surgery (LECS) is used to combine endoscopic and laparoscopic surgeries, fully realizing their respective advantages and avoiding their drawbacks. The main steps are as follows. First, gastroscopy and laparoscopy are combined to confirm the location and boundary of the tumor. Tumor resection is carried out laparoscopically, guided by a gastroscope. The specimen is removed orally and the gastric wound closed laparoscopically. Then, gastroscopy and laparoscopy are combined to determine whether there is wound bleeding, if the suture is satisfactory, and if the gastric cavity is deformed.
LECS has natural advantages in the treatment of G-GISTs that are less than 5 cm in size. The accurate estimation of tumor location and boundary greatly improves the complete resection rate of tumors. The risk of tumor rupture is substantially reduced, and the long-term prognosis of patients is significantly improved. The process allows for accurate resection of the tumor, maximum preservation of normal gastric tissue and organ function, and avoids postoperative gastric deformation. The patient's postoperative rehabilitation is greatly accelerated, and oral feeding can resume on the day of the operation. The specimen is taken out through the mouth to avoid the need for an extended abdominal incision. This greatly reduces the patient's postoperative pain and scarring. The method greatly shortens the postoperative hospital stay (i.e., discharge is possible on the day after the operation), increasing the turnover of hospital beds.

Laparoscopy-endoscopy cooperative surgery is appropriate for the treatment of gastric gastrointestinal stromal tumors less than 5 cm in size. It can achieve the respective advantages of endoscopic and laparoscopic surgeries while avoiding their drawbacks.

Laparoscopic Oocyte Retrieval and Cryopreservation during Vaginoplasty for Treatment of Mayer-Rokitansky-Kuster-Hauser Syndrome

In Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKHS) patients who are scheduled for laparoscopic vaginoplasty and have a desire for biological motherhood, we propose that a concomitant laparoscopic oocyte retrieval for cryopreservation is performed. Oocyte retrieval is pursued at the beginning of the laparoscopy. Right and left 5 mm trocars are positioned, through which a 17 G ovum aspiration needle is used for puncture of the right and left ovaries, respectively. To facilitate exposure of the follicles, the ovaries are mobilized and held with laparoscopic forceps.
When aspirating multiple follicles near each other, the needle tip is retained in the ovary to reduce the number of times that the ovarian cortex is transfixed and due to the inherent risk of bleeding. Subsequent steps are unchanged compared to the Davydov laparoscopic modified technique for vaginoplasty. Prior to surgery, controlled ovarian stimulation is performed with a gonadotropin hormone-releasing hormone (Gn-RH) antagonist protocol, and the concomitant procedure of oocyte retrieval and vaginoplasty is scheduled 36 h after the final follicular maturation trigger. Follicular fluid is collected in the same 10 mL sterile tubes used during transvaginal oocyte retrieval and transferred in a warming block (37 &#176;C) to the assisted reproduction laboratory, where mature (metaphase II) oocytes are vitrified.
In this case, a series of 23 women with MRKH, oocytes were successfully retrieved and cryopreserved in all patients; vaginoplasty was subsequently conducted without modifications, and the inpatient and outpatient postoperative care (day of urinary catheter removal, day of hospital discharge, dilator use, and comfort at follow-up) remained unaffected. One postoperative complication occurred in one patient (fever developing on day 5 post surgery and intraperitoneal fluid detection on transabdominal ultrasound) and resolved after conservative treatment. Rather than performing surgical vaginoplasty and delaying oocyte retrieval in MRKH patients, this approach combines both procedures in a single laparoscopy, thereby minimizing surgical invasiveness and anesthesiologic risks.

A dedicated team can offer Mayer-Rokitansky-Kuster-Hauser patients the option to perform controlled ovarian stimulation and oocyte cryopreservation at the time of laparoscopic vaginoplasty.

Modified Posterior Vertebral Column Resection for Patients with Thoracolumbar Kyphotic Deformity

Old compression vertebrae fracture or congenital kyphoscoliosis with abnormal vertebral body development and other diseases that invade the spine may cause severe thoracolumbar kyphotic deformity, often accompanied by intractable low back pain or compression of the spinal cord, leading to severe neurological symptoms or even paralysis. If conservative treatment cannot relieve the symptoms or correct the deformities, surgical treatment is usually needed. For severe kyphotic deformity, reconstruction of the physiological curvature and rigid fixation determine the prognosis of the patients. Osteotomy and orthopedics are the standard procedure for deformities with severe compression of the front and middle column, but the trauma to the patients is high, with a long operation time and massive blood loss. To avoid these disadvantages, we have developed a modified technique to remove the diseased vertebra unilaterally. In this technique, we use a modified trephine to resect the vertebral columns like in the pedicle screw technique by adding a locking instrument that can restrict the trephine to lower the risk of osteotomy and shorten the surgery time and blood loss.

We describe a modified technique for resecting the posterior vertebral column unilaterally based on a modified trephine for patients with thoracolumbar kyphotic deformity.

Use of the Scissor-Type Knife During the Peroral Endoscopy Myotomy Procedure for the Treatment of Achalasia

Peroral endoscopic myotomy (POEM) is one of the first-line treatment modalities along with pneumatic dilation and Heller myotomy for patients with achalasia. Endoscopists, especially trainees during the learning phase, commonly face difficulty in tissue plane dissection and selective myotomy while working near the esophagogastric junction, with increased risks of inadvertent injury, unexpected bleeding, and inadequate myotomy. To minimize the technical difficulty and improve the safety of POEM, we describe a protocol for using a scissor-type knife for the main steps of POEM, including mucosal incision, submucosal tunneling, myotomy, and hemostasis. The standard techniques used with the scissor-type knife involve grasping the target tissue, and then dissection or coagulation. The confirmation of the cutting line after grasping improves the accuracy and reliability of dissection, which is particularly useful for the selective myotomy of the internal circular muscle. Meanwhile, the scissor-type knife provides enhanced hemostatic capability and enables hemostasis and pre-coagulation without the device exchange for hemostatic forceps. Evaluation of the clinical outcomes in three patients who successfully received POEM using the scissor-type knife revealed no perioperative adverse events. At the 3-month follow-up, all patients achieved clinical success with postoperative Eckardt scores ranging from 0 to 1. In conclusion, the use of a scissor-type knife could minimize the technical difficulty and improve the safety of the POEM procedures, which may be suitable for trainees during the learning phase.

To minimize the technical difficulty and improve the safety of peroral endoscopic myotomy (POEM), we describe a protocol for using a scissor-type knife for the main steps of POEM, including mucosal incision, submucosal tunneling, myotomy, and hemostasis.

Clinical Application of Single-Surgeon, Three-Port, Laparoscopic Resection for Colorectal Cancer with Natural Orifice Specimen Extraction

Reduced-port laparoscopic surgery (RPLS) has been widely used for the radical resection of gastrointestinal tumors. Single-surgeon, three-port, laparoscopic radical resection for sigmoid colon or high rectal cancer with natural orifice specimen extraction surgery (NOSES) has the advantage of a small incision, quick postoperative recovery, and short hospital stay. Yet, there are still only a few reports on NOSES. This paper describes the indications, preoperative preparations, surgical steps, and precautions for single-surgeon, three-port, laparoscopic radical resection of the sigmoid colon and high rectal cancer, and intraoperative specimen collection through the natural orifice. 
The protocol focuses on the steps of radical dissection and the main technical points of resection and reconstruction. At the same time, a procedure for fixing an anvil seat by self-traction of extracorporeal silk thread, used for purse-string suture fixation after the proximal anvil was placed in the abdominal cavity, was creatively improved. This operation could effectively avoid problems such as an insufficient proximal intestinal tube, shaking off the anvil seat, and weak purse-string suture during a single operation. The surgical care had less variability and was easy to perform, effectively avoiding postoperative anastomotic leakage and bleeding due to excessive intraoperative anastomotic tissue. This surgery could be widely promoted in primary hospitals.

Here, we present a protocol to successfully perform single-surgeon, three-port, laparoscopic resection for colorectal cancer with natural orifice specimen extraction.

Microscopic Cyst Resection for the Treatment of Patients Diagnosed with Epididymal Cyst

Epididymal cysts mostly occur in men aged 20-40 years old. Previous reports have covered concerns about postoperative complexes, including postoperative asoedema, hematoma, sustaining pain, and seminal tract obstruction in patients who have undertaken nonmicroscopic epididymal cyst resection or epididymal resection. Nonmicroscopic epididymal cyst surgery is suggested for patients with childbirth plans as a precaution. The treatment of male epididymal cysts via microtechnology is obviously a beneficial option; we took the lead in carrying out microscopic epididymal exploration and cyst resection surgery in China. From September 2017 to April 2021, 41 young and middle-aged male patients diagnosed with epididymal cysts underwent microtechnology treatment in a program titled &#34;microscopic epididymal exploration and cystectomy&#34;. The postoperative follow-up lasted for 3-50 months. The results confirmed that, as microscopic manipulation largely improved visualization of the subtle tissue structures of the epididymis, the cyst could be clearly dissected apart and completely removed intact under the microscope. Bleeding during the operation was significantly reduced (2-3 mL) and wound drainage was not required. According to follow-up data, microscopic treatment significantly reduced the incidence of postoperative scrotal hematoma, edema, and long-term postoperative pain, thereby promising a higher surgical success rate as well as recurrence prevention. Besides, preliminary experience and reflection suggest that microscopic epididymal exploration and cystectomy provide efficient preservation of the epididymal patency through refined treatment, while a better prognosis can be achieved. We recommend that surgery be carried out before the epididymal cyst develops to 0.8 cm in diameter, for fear that a larger epididymal cyst (&#62;0.9 cm in diameter) could cause the complete destruction of all tubules of the ipsilateral epididymis - a more severe case with damage to the testicular output network.

Here, we present a protocol to treat patients diagnosed with an epididymal cyst using microscopic cyst resection. Based on microscopic manipulation, a largely improved visualization of the subtle tissue structures of the epididymis was obtained, so the cyst could be clearly dissected apart and completely removed intact.

A Non-Intubation Protocol for Video-Assisted Thoracoscopic Surgery with Preserved Autonomic Breathing

Non-Intubated Video-Assisted Thoracoscopic Surgery

Double-lumen intubation under general anesthesia is currently the most commonly performed intubation technique for pneumonectomy, wedge resection of the lung, and lobectomy. However, there is a high incidence of pulmonary complications arising from general anesthesia with tracheal intubation. Non-intubation with the preservation of voluntary breathing is an alternative to anesthesia. Non-intubation procedures minimize the adverse effects of tracheal intubation and general anesthesia, such as intubation-related airway trauma, ventilation-induced lung injury, residual neuromuscular blockade, and post-operative nausea and vomiting. However, the steps for non-intubation procedures are not detailed in many studies. Here, we present a concise non-intubated protocol for the performance of video-assisted thoracoscopic surgery with preserved autonomic breathing. This article identifies the conditions necessary to convert from non-intubated to intubated anesthesia and also discusses the advantages and limitations of non-intubated anesthesia. In this work, this intervention was performed on 58 patients. In addition, the results of a retrospective study are presented. Compared with intubated general anesthesia, patients in the non-intubated video-assisted thoracic surgery group had lower rates of post-operative pulmonary complications, shorter operative times, less intraoperative blood loss, shorter PACU stays, a lower number of days to chest drain removal, less post-operative drainage, and shorter hospital stays.
