The LoCoSP device allows for safer surgery using a transcervical approach in minimally invasive THE. This is accomplished by improving the recognition and dissection of the esophagus, trachea, and the aortic arch under magnified vision. The advantages of THE are amplified. In addition to allowing surgery with less morbidity and fewer pulmonary complications, this technique can improve the dissection of left paratracheal and recurrent lymph nodes. Another advantage of this technique is that it is possible to reduce the ri...

There are multiple options for the treatment of esophageal cancer, which involve endoscopy, surgery1, neoadjuvant, and definitive treatment with chemoradiotherapy2. Esophagectomy is the most important element in the curative treatment of patients with advanced esophageal cancer3, and the two main approaches currently used for surgical treatment are transthoracic esophagectomy (TTE) and transhiatal esophagectomy (THE). However, the choice of approach remains controversial. Since TTE requires pulmonary collapse during surgery, more frequent pulmonary complications are to be expected than in a transhiatal approach. Minimally invasive techniques are used to reduce access trauma to the lungs and others structures of the thorax, but they do not decrease the morbidity in comparison to THE. Thus, minimally invasive THE has become a more attractive option; however, the upper esophagus and upper mediastinum are difficult areas to dissect due to blind areas, and cervical incision might be not enough to allow a safe dissection of the upper part.
Laparoscopic THE reduces morbidity4 and enhances postoperative recovery with no compromise in cancer recurrence or survival5. THE has been shown to decrease the hospital stay, hospital mortality, surgical time, and blood loss. Furthermore, TTE has a higher risk of pulmonary complications. The patient's stay in the intensive care unit is significantly longer after transthoracic resection, and hospital stay is also significantly prolonged. 
However, there is an issue with THE regarding the lymph node dissection, particularly in the upper mediastinum, which is a blind area. This results in a risk of tracheal and vascular lesions during the surgery. Tokairin6 et al. and Fujiwara et al. described a single-port mediastinoscopic method for upper mediastinal dissection in esophageal cancer surgery. This technique enabled clear visualization of the structures around the aortic arch and safe lymphadenectomy7. A low-cost single-port device was developed to improve upper mediastinal dissection using a left transcervical mediastinoscopic approach, which was used to improve the visibility and dissection in the upper mediastinum around the aortic arch. The aim of this project is to describe the step-by-step process of a laparoscopic THE completed using a mediastinoscopy cervical approach with a low-cost single-port device in a rendezvous technique.

low-cost single-port (locosp) device for a transcervical approach in minimally invasive transhiatal esophagectomy

Esophagectomy remains the preferred option to achieve curative treatment in advanced esophageal cancer, but the choice of surgical approach remains controversial. A transthoracic approach may improve lymph node dissection, but it has considerable morbidity and respiratory complications. Transhiatal access has been demonstrated as an efficient means of minimizing post-operative complications. Minimally invasive transhiatal esophagectomy may reduce operative trauma and morbidity as well as enhance postoperative recovery with no compromise in cancer recurrence or survival. Nevertheless, it has a technical limitation in terms of cervical esophagus dissection. Thus, a low-cost single-port device was developed to complete upper mediastinal dissection by a transcervical approach during minimally invasive transhiatal esophagectomy. This device uses a nasogastric tube, a number-eight sterile glove, a sterile sponge, and 3 permanent 5-mm trocars. The step-by-step process of transhiatal esophagectomy and the development of this device are described. This technique allows for the dissection of the upper mediastinum, as well as the esophagus over the aortic arch and behind the superior portion of the trachea. The harvesting of lymph nodes along the left recurrent laryngeal nerve and paratracheals was improved.

The LoCoSP device is a useful tool for safely dissecting the structures of the upper mediastinum. Direct visualization of the cervical and upper thoracic esophagus allows for safe dissection with less risk of tracheal injury and hemorrhage from tearing of the larger vessels, in addition to improving the lymphadenectomy of the left recurrent laryngeal and paratracheal nodes.
From 2018 to 2020, 12 patients with distal esophageal carcinoma (2 squamous cell carcinoma and 10 adenocarcinoma) were su...

Single Port Donor Nephrectomy

In 2007, Rane presented the first single port nephrectomy for a small non-functioning kidney at the World Congress of Endourology. Since that time, the use of single port surgery for nephrectomy has expanded to include donor nephrectomy. Over the next two years the technique was adopted for many others types of nephrectomies to include donor nephrectomy. We present our technique for single port donor nephrectomy using the Gelpoint device. We have successfully performed this surgery in over 100 patients and add this experience to our experience of over 1000 laparoscopic nephrectomies. With the proper equipment and technique, single port donor nephrectomy can be performed safely and effectively in the majority of live donors. We have found that our operative times and most importantly our transplant outcomes have not changed significantly with the adoption of the single port donor nephrectomy. We believe that single port donor nephrectomy represents a step forward in the care of living donors.

Single port laparoscopic surgery is changing the standard of care in surgical care like nothing since the laparoscopic technique was introduced 20 years ago. We present out technique of single port donor nephrectomy using the Gelpoint device. We have successfully performed this surgery in 100 patients.

An Ivor Lewis Esophagectomy Designed to Minimize Anastomotic Complications and Optimize Conduit Function

We describe a novel esophagogastric anastomotic technique (&ldquo;side-to-side: staple line-on-staple line&rdquo;, STS) for intrathoracic anastomoses designed to create a large diameter anastomosis while simultaneously maintaining conduit blood supply. This technique aims to minimize the incidence of anastomotic leaks and strictures, which is a frequent source of morbidity and occasional mortality after esophagectomy. We analyze the results of this STS technique on 368 patients and compared outcomes to 112 patients who underwent esophagogastric anastomoses using an end-to-end stapler (EEA) over an 8-year time interval at our institution.
The STS technique involves aligning the remaining intrathoracic esophagus over the tip of the lesser curve staple line of a stomach tube, created as a replacement conduit for the esophagus. A linear stapling device cuts through and restaples the conduit staple line to the lateral wall of the esophagus in a side-to-side fashion. The open common lumen is then closed in two layers of sutures.
There was a total of 12 (3.8%) anastomotic leaks in patients who underwent STS esophagogastric anastomosis. Two of eight patients (25%) had anastomotic leaks after esophagectomy for end-stage achalasia as compared to a 2.8% leak rate (10/336) after esophagectomy for other conditions. Eighteen (5.2%) patients required a median of 2 dilatations for anastomotic stricture after STS anastomosis. Supplemental jejunostomy feedings were required in only 11.1% of patients undergoing STS anastomoses following hospital discharge. In contrast, patients undergoing EEA anastomoses demonstrated anastomotic leak and stricture rates of 16.1% and 14.3% respectively (p&lt;0.01). Time analysis of postoperative contrast studies following the STS technique typically demonstrated a straight/uniform diameter conduit with essentially complete contrast emptying into the small bowel within 3 minutes in 88.4% of patients.
The incidence of esophagogastric anastomotic leaks and strictures were extremely low using this novel anastomotic technique. Additionally we believe that based on time and qualitative analyses of postoperative contrast studies, this technique appears to optimize postoperative upper gastrointestinal tract function; however, further comparative studies are needed.

We describe a novel intrathoracic esophagogastric anastomotic technique designed to create a large diameter anastomosis while simultaneously maintaining conduit blood supply to minimize the incidence of anastomotic leaks and strictures. Construction and orientation of the stomach conduit designed to optimize upper gastrointestinal tract function is also described.

Electromagnetic Navigation Transthoracic Nodule Localization for Minimally Invasive Thoracic Surgery

The increased use of chest computed tomography (CT) has led to an increased detection of pulmonary nodules requiring diagnostic evaluation and/or excision. Many of these nodules are identified and excised via minimally invasive thoracic surgery; however, subcentimeter and subsolid nodules are frequently difficult to identify intra-operatively. This can be mitigated by the use of electromagnetic transthoracic needle localization. This protocol delineates the step-by-step process of electromagnetic localization from the pre-operative period to the postoperative period and is an adaptation of the electromagnetically guided percutaneous biopsy previously described by Arias et al. Pre-operative steps include obtaining a same day CT followed by the generation of a three-dimensional virtual map of the lung. From this map, the target lesion(s) and an entry site are chosen. In the operating room, the virtual reconstruction of the lung is then calibrated with the patient and the electromagnetic navigation platform. The patient is then sedated, intubated, and placed in the lateral decubitus position. Using a sterile technique and visualization from multiple views, the needle is inserted into the chest wall at the prechosen skin entry site and driven down to the target lesion. Dye is then injected into the lesion and, then, continuously during needle withdrawal, creating a tract for visualization intra-operatively. This method has many potential benefits when compared to the CT-guided localization, including a decreased radiation exposure and decreased time between the dye injection and the surgery. Dye diffusion from the pathway occurs over time, thereby limiting intra-operative nodule identification. By decreasing the time to surgery, there is a decrease in wait time for the patient, and less time for dye diffusion to occur, resulting in an improvement in nodule localization. When compared to electromagnetic bronchoscopy, airway architecture is no longer a limitation as the target nodule is accessed via a transparenchymal approach. Details of this procedure are described in a step-by-step fashion.

Presented here is a protocol for lung nodule localization using dye marking via electromagnetically navigated transthoracic needle access. The technique described here can be accomplished in the peri-operative period to optimize nodule localization and to successful resection when performing minimally invasive thoracic surgery.

Full-Endoscopic Transforaminal Approach for Lumbar Discectomy

With technical advancements, the full-endoscopic transforaminal approach for lumbar discectomy (ETALD) is gaining popularity. This technique utilizes various tools and instruments, including a dilator, a beveled working sleeve, and an endoscope with a 20-degree angle and 177 mm length, equipped with a 9.3-diameter oval shaft and a 5.6 mm diameter working channel. Additionally, the procedure involves using a Kerrison punch (5.5 mm), rongeur (3-4 mm), punch (5.4 mm), tip control radioablator applying a radiofrequency current of 4 MHz, fluid control irrigation and suction pump device, 5.5 mm oval burr with lateral protection, burr round, and the diamond round. During the surgery, it is essential to identify significant landmarks, including the caudal pedicle, ascending facet, annulus fibrosis, posterior longitudinal ligament, and the exiting nerve root. The steps of the technique are relatively easy to follow, especially when utilizing the appropriate instruments and having a good understanding of the anatomy. Research studies have demonstrated comparable outcomes to open microdiscectomy techniques. ETALD presents itself as a safe option for lumbar discectomy, as it minimizes tissue disruption, results in low postoperative surgical site pain, and allows for early mobilization.

The present protocol describes the full-endoscopic transforaminal approach for lumbar discectomy, which is a safe technique that does not require muscle retraction or bone removal.

Laparoscopic Radical Antegrade Modular Pancreatosplenectomy via Dorsal-Caudal Artery Approach for Pancreatic Neck-Body Cancer

Laparoscopic radical resection of the pancreatic neck is one of the most complicated radical operations for pancreatic cancer, especially for patients who have had neoadjuvant chemotherapy. Here, we present a technique to perform laparoscopic radical antegrade modular pancreatosplenectomy (L-RAMPS) using the dorsal-caudal artery approach by making full use of the high-definition vision and operation modes of the laparoscope.
The innovation and optimization of this operation are provided in the protocol. Priority should be given to the dorsal resection plane, including the dorsal side of the superior mesenteric artery (SMA), the dorsal side of the pancreatic head, the root of the celiac artery (CeA), the ventral side of the left renal vessels, and the renal hilum. On the condition that the operation for pancreatic neck-body cancer is feasible and safe, the second step is to perform tumor resection en bloc surrounding the SMA and CeA from the caudal to the cephalic side to increase the rate of R0 (radical zero) resection and further prognosis.

Laparoscopic Radical Antegrade Modular Pancreatosplenectomy via Dorsal-Caudal Artery Approach for Pancreatic Neck-Body Cancer

Transoral Endoscopic Thyroidectomy Vestibular Approach for Thyroid Lobectomy

The manuscript describes the transoral endoscopic thyroidectomy vestibular approach (TOETVA) for thyroid lobectomy. The patient is placed in the supine position with extension and fixation of the neck. One 20 mm transverse incision and two 5 mm incisions are made through the mucosa of the oral vestibule for camera and instrument placement after disinfection of the skin and oral cavity. The workspace is established and maintained by the skin suspension device, which is made of unabsorbable string (3-0) and rubber bands, and the CO2 insufflation pressure. Lobectomy using a medial-to-lateral technique and prophylactic ipsilateral central neck dissection is performed simultaneously on patients with papillary thyroid cancer (PTC). The specimen is extracted through the 20 mm incision. The parathyroid gland is immediately searched for in the specimen and auto-transplanted to the left brachioradialis. A drainage tube is inserted through the retractor hole into the bed of the thyroid gland, and absorbable sutures are used to close the mucosal incisions in the oral vestibule and the linea alba cervicalis. Prophylactics administered intravenously are recommended for the first 24 h after surgery, and oral antibiotics are used for 7 days postoperatively.

Here, we present a protocol to describe the methodology for the transoral endoscopic thyroidectomy vestibular approach in detail.

Gasless Endoscopic Thyroidectomy via the Trans-Axillary Approach

For patients with early, low-risk papillary thyroid carcinoma, an increasing number are opting for endoscopic thyroid surgery due to its ability to achieve favorable therapeutic outcomes while maintaining excellent cosmetic results. Among the available endoscopic procedures, the Gasless Endoscopic Thyroidectomy Trans-axillary Approach (GETTA) has gained popularity among surgeons. This is attributed to its straightforward cavity construction, spacious operating area, precise visual field exposure, and manageable learning curve. However, few studies have provided detailed descriptions of the specific surgical steps involved in GETTA. Drawing from a synthesis of existing literature and our own clinical expertise, we present a comprehensive outline of the GETTA procedure. This process can be categorized into five distinct stages: positioning and incision planning; establishment of surgical cavities; identification and protection of the recurrent laryngeal nerve, inferior parathyroid gland, and central neck dissection; localization and preservation of the superior laryngeal nerve, superior parathyroid gland, and dissection of the thyroid's superior pole; transection of the thyroid isthmus followed by en bloc resection of the thyroid gland and central neck lymph nodes. The five-step approach of GETTA is easy to learn and can be adapted for resecting both benign and malignant thyroid and parathyroid diseases.

Reoperative Hiatal Hernia Repair

Technical Considerations and Approach to Redo Foregut Surgery

Foregut surgical techniques have advanced significantly over the years and have become increasingly popular. However, new challenges and technical considerations have arisen when dealing with reoperation for complications or surgical failure. This study focuses on the technical considerations and approach when dealing with reoperative foregut surgery, particularly redo&#160;hiatal hernia repair. We describe our approach starting from the preoperative workup to the procedural steps of the surgery. The present study describes the main steps for robotic reoperative hiatal hernia repair in a patient who had previously undergone laparoscopic hiatal hernia repair with Nissen fundoplication but did not present a recurrence of reflux and dysphagia symptoms. The patient is positioned supine with arms out and a footboard for steep Trendelenburg. We place six trocars, including an assistant port and a liver retractor port,&#160;to facilitate visualization and retraction. After docking the robot, we use a combination of electrocautery and sharp dissection&#160;to free the hernia sac and reduce the hiatal hernia. The previous fundoplication is then taken down carefully and the esophagus is mobilized through a transhiatal approach with a combination of blunt and sharp dissection until at least 3 cm of intra-abdominal esophageal length is achieved, after which a leak test is performed. We then perform a crural repair to reapproximate the hiatus with two posterior stitches and one anterior stitch. Lastly, a redo Nissen fundoplication is performed over a bougie, and endoscopy is used to confirm a loose stack-of-coin appearance. By emphasizing the crucial steps of redo hiatal hernia repair, including preoperative evaluation, our goal is to provide an approach for the foregut surgeon to maximize patient outcomes.

Laparoscopic Duodenum-Preserving Pancreatic Head Resection via Inferior Infracolic Approach: A Surgical Approach for Benign Lesions

Minimally invasive pancreatic resections are gaining popularity despite being technically demanding. However, in contrast to laparoscopic pancreatoduodenectomy (LPD), laparoscopic duodenum-preserving pancreatic head resection (LDPPHR) has not yet obtained wide acceptance. This could be attributed to the technical challenges involved in preserving the blood supply of the duodenum and bile duct.
This study describes and demonstrates all the steps of LDPPHR. A 48-year-old woman was diagnosed with a 3.0 cm x 2.5 cm pancreatic head cystic mass, which was detected unexpectedly. The surgery was performed using the 3D laparoscopy via an inferior infracolic approach. The operation lasted approximately 310 min with 100 mL of blood loss. Postoperatively, the patient experienced no complications and was discharged 5 days later. Pathology revealed intraductal papillary mucinous neoplasms.
LDPPHR via an inferior infracolic approach is feasible and safe when performed by experienced surgeons in selected patients with thin mesenteric fat layers. The described technique for LDPPHR via inferior infracolic approach should be well standardized and performed at high-volume centers with experienced surgeons in both open and laparoscopic pancreatology.

This article provides a whole technical process of laparoscopic duodenum-preserving pancreatic head resection via an inferior infracolic approach. This is a surgical approach for benign tumors without intraoperative fluorescence image guidance.

Treatment of Achalasia by Robot-Assisted Heller Myotomy

Robotic Heller Myotomy for Advancements in Surgical Management of Achalasia

Achalasia is an esophageal motility disorder. It occurs due to the destruction of nerves in the lower esophageal sphincter (LES), which leads to the failure of the LES to relax. Patients typically complain of dysphagia, chest pain, and regurgitation. They often report drinking liquids with solids intake to help propel food boluses into the stomach. The diagnosis of achalasia is typically confirmed with an esophagogram and a motility study (esophageal manometry). An esophagogram classically shows the bird beak sign with tapering in the distal esophagus. The treatment for achalasia includes both surgical and non-surgical options. Surgical treatment is associated with a lower rate of recurrences, high clinical success rate, and durability of symptom relief. The current gold standard of surgical technique is myotomy, or the dividing of the muscle fibers of the distal esophagus. Surgical myotomy can be accomplished via a laparoscopic or robotic technique; per-oral endoscopic myotomy is a new alternative intervention. Due to the theoretical risk of gastroesophageal reflux following a myotomy, an antireflux procedure is sometimes performed. We reviewed the approach to a robotic heller myotomy for the treatment of achalasia.
