Esophagectomy – minimally invasive. Minimally invasive esophagectomy esploration Robotic esophagectomy ; Removal of the esophagus – minimally invasive ; Achalasia – esophagectomy ; Barrett esophagus – esophagectomy ; Esophageal cancer – esophagectomy – laparoscopic; Cancer of the The last decade has witnessed nationwide growth in the application of MIE and yielded a significant amount of scientific data in support of its clinical merits and advantages.

Surgical team proficiency in minimally invasive esophagectomy is related to case volume and improves patient outcomes. Minimally invasive esophagectomy MIE is being increasingly performed; however, it is still associated with high morbidity and mortality.

The correlation between surgical team proficiency and patient load lacks clarity. Rxploration study evaluates surgical outcomes during the first 3-year period after establishment of a new surgical team. A new surgical team was established in September by two expert surgeons having experience of performing more than MIEs. We assessed consecutive patients who underwent MIE for esophageal cancer and evaluated the impact of surgical team proficiency on postoperative outcomes, as well as cortticosurrenale team learning curve.

In the cumulative sum analysis, a point of downward inflection for operative biovhimique and blood loss was observed in case Surgical expolration proficiency based on team experience had beneficial effects on patients undergoing MIE. Open esophagectomy is a high-risk procedure in patients with liver cirrhosis. With the advent of minimally invasive surgical techniques, the overall morbidity and mortality rates of esophagectomy have decreased.

The aim of this study was to describe short-term outcomes of minimally invasive esophagectomy in patients with proven liver cirrhosis. Retrospective observational cohort study. Demographics, preoperative clinical characteristics, and outcomes of patients undergoing minimally ckrticosurrenale esophagectomy for carcinoma were analyzed. Patients with concomitant liver cirrhosis were compared to patients without liver cirrhosis undergoing similar surgical procedures.

In addition, variables possibly associated with postoperative morbidity and mortality in patients with cirrhosis were investigated.

Out of patients undergoing minimally invasive esophagectomy18 4. Demographics and preoperative clinical variables were similar in the 2 patient groups. There was a significantly higher rate of sepsis and anastomotic, respiratory, and hemorrhagic complications in patients with liver cirrhosis who died in the postoperative period. Minimally invasive esophagectomy is feasible in patients with liver cirrhosis. Future strategies should focus on total minimally invasive procedures and early recognition of surgical complications.

Hybrid minimally invasive esophagectomy for cancer: The purpose of this case-control study was to evaluate the impact of hybrid minimally invasive esophagectomy for cancer on surgical stress response and nutritional status.

All 34 consecutive patients undergoing hybrid minimally biochimlque esophagectomy for cancer at our surgical unit between and were retrospectively compared with 34 patients undergoing esophagectomy with open gastric tubulization openmatched for neoadjuvant therapy, pathological stage, gender and age. Demographic data, tumor features and postoperative course including quality of life and systemic inflammatory and nutritional status were compared.

Postoperative course was similar in terms of complication rate. Hybrid minimally invasive esophagectomy significantly improved the systemic inflammatory and catabolic response to surgical trauma, contributing to a shorter length of stay in intensive care unit. Robot-assisted minimally invasive thoraco-laparoscopic esophagectomy versus open transthoracic esophagectomy for resectable esophageal cancer, a randomized controlled trial ROBOT trial. For esophageal cancer patients, radical esophagolymphadenectomy is the cornerstone of multimodality treatment with curative intent.


Transthoracic esophagectomy is the preferred surgical approach worldwide allowing for en-bloc resection of the tumor with explogation surrounding lymph nodes. Recent studies have shown that robot-assisted minimally invasive thoraco-laparoscopic esophagectomy RATE is at least equivalent to the open transthoracic approach for esophageal cancer in terms of short-term oncological outcomes.

RATE was accompanied with xorticosurrenale blood loss, shorter ICU stay and improved lymph node retrieval exploratiom with open esophagectomyand the pulmonary complication rate, hospital stay and perioperative mortality were comparable.

The objective is to evaluate the efficacy, risks, quality of life and cost-effectiveness of RATE as an alternative to open transthoracic esophagectomy for treatment of esophageal cancer. This is an investigator-initiated and investigator-driven monocenter randomized controlled parallel-group, superiority trial. The primary outcome of this study is the percentage of overall complications grade 2 and higher as stated by the modified Clavien-Dindo classification of surgical complications.

This is the first randomized controlled trial designed to compare RATE with open transthoracic esophagectomy as surgical treatment for. Lewis esophagectomyBlunt esophagectomy ; Esophageal cancer – esophagectomy – open; Cancer of the esophagus – esophagectomy – open Thoracoscopic management of volvulus of the gastric conduit following minimally invasive Ivor-Lewis esophagectomy.

We present a case of emergent thoracoscopic management of volvulus of the gastric conduit following minimally invasive Ivor-Lewis esophagectomy.

The patient is a year-old Caucasian male with a history of adenocarcinoma of the lower third of the esophagus.

Initial presentation was dysphagia with solid foods, which progressed in severity until he was unable to swallow anything. PET scan did not reveal any metastatic disease. Preoperative management included neo-adjuvant chemoradiation therapy 5-FU and cisplatin and explpration placement of a jejunal feeding tube.

Intra-operative leak test was performed as a matter of routine following completion of the esophagogastric anastomosis. A nasogastric tube was placed intra-operatively and removed on POD2 corticosurrrnale to our standard pathway. Postoperatively, the patient progressed without difficulty to POD4, when we routinely obtain an upper GI swallow study. This demonstrated a lack of transit of contrast through the distal neo-esophagus. Follow-up endoscopy revealed volvulus of the gastric conduit with obliteration of the corticosurrrenale.

We immediately took the patient to the OR for thoracoscopic detorsion, which we accomplished successfully by entering the existing trochar sites and using blunt dissection. Attachments were gently teased away from the chest wall and the conduit was detorsed and anchored to the chest wall in the correct orientation with silk suture.

Intra-operative endoscopy demonstrated a patent conduit. Postoperative upper GI fluoroscopy now showed good transit of contrast. The patient continued to improve and was eventually advanced to mechanical soft diet and discharged on postoperative day 9.

Early intervention is indicated in cases of volvulus of the gastric conduit following Ivor. Although esophageal cancer is rare in the United States, 5-year survival and quality of life Corticosurremale are poor following esophageal cancer surgery. Although esophageal cancer has been surgically treated with esophagectomy through thoracotomy, an open procedure, minimally invasive surgical procedures have been recently cortifosurrenale to decrease the risk of exploratin and improve QoL after surgery.

The current study is a systematic cortiocsurrenale of the published literature to assess differences in QoL after traditional open or minimally invasive esophagectomy. We hypothesized that QoL is consistently better in patients treated with minimally invasive surgery than in those treated with a more traditional and invasive approach. Although global health, social function, and emotional function improved more commonly after minimally invasive surgery compared with open surgery, physical function and role function, as well as symptoms including choking, dysphagia, eating problems, and trouble swallowing saliva, declined for both surgery types.

Cognitive function was equivocal across both groups. The potential small benefits in global and mental health status among those who experience minimally invasive surgery should be considered with caution given the possibility of publication and selection exploratino.


Navigation exploratoin for minimally invasive esophagectomy: Navigation systems potentially facilitate minimally invasive esophagectomy and improve patient outcome by improving intraoperative orientation, position estimation of instruments, and identification of lymph nodes and resection margins. The authors’ self-developed navigation system is highly accurate in static environments.

This study aimed to test the overall accuracy of the navigation system in a realistic operating room scenario and to identify the different sources of error altering accuracy.

Computed tomography imaging was followed by image segmentation and target definition with the medical imaging interaction toolkit software.

Optical tracking was used for registration and localization of animals and navigation instruments. Intraoperatively, the instrument was displayed relative to segmented organs in real time. The target registration error TRE of the navigation system was defined as the distance between the target and the navigation instrument tip.

The TRE on the esophagus was The main source of error was soft tissue deformation caused by intraoperative positioning, pneumoperitoneum, surgical manipulation, and tissue dissection.

The navigation system obtained acceptable accuracy with a minimally invasive transhiatal approach to the esophagus in a realistic experimental model. Thus the system has the potential to improve intraoperative orientation, identification of lymph nodes and adequate resection margins, and visualization of risk structures.


Compensation methods for soft tissue. Gastrobronchial fistula following minimally invasive esophagectomy for esophageal cancer in a patient with myotonic dystrophy: Introduction Myotonic dystrophies are inherited multisystemic diseases characterized by musculopathy, cardiac arrythmias and cognitive disorders.

These patients are at increased risk for fatal post-surgical complications from pulmonary hypoventilation. We present a case with myotonic dystrophy and esophageal cancer who had a minimally invasive esophagectomy complicated with gastrobronchial fistulisation.

Presentation of case A year-old male with myotonic dystrophy type 1 and esophageal cancer had a minimally invasive esophagectomy performed instead of open surgery in order to reduce the risk for pulmonary complications.

In order to minimize large leakage of air into the gastric conduit the anastomosis was stented and ventilation maintained at low airway pressures.

His general condition improved and allowed extubation at day 29 and stent removal at day Bronchoscopy confirmed that the fistula was healed. The patient was discharged from hospital at day 37 without further complications. Discussion The fistula was probably caused by bronchial necrosis from thermal injury during close dissection using the Ligasure instrument. Fistula treatment by non-surgical intervention was considered safer than surgery which could be followed by potentially life-threatening respiratory complications.

Indications for stenting of gastrobronchial fistulas will be discussed. Conclusions Minimally invasive esophagectomy was performed instead of open surgery in a myotonic dystrophy patient as these patients are particularly vulnerable to respiratory complications. Gastrobronchial fistula, a major complication, was safely treated by stenting and low airway pressure ventilation.

Objectives In expert hands, the intra-thoracic esophago-gastric anastamosis usually provides a low rate of strictures and leaks. However, anastomoses can be technically challenging and time consuming when minimally invasive techniques are used. Materials and Methods We evaluated a prospective cohort of 37 consecutive patients offered minimally invasive Ivor Lewis Esophagectomy at a tertiary referral center.

The esophagogastric anastomosis was created using a 25mm anvil Orvil, Autosuture, Norwalk, CT passed trans-orally, in a tilted position, and connected to a 90cm long PVC delivery tube through an opening in the esophageal stump. Primary outcomes were leak and stricture rates. The abdominal portion of the operation was completed laparoscopically in 30 patients The thoracic portion was done using a muscle sparing mini-thoracotomy in 23 patients There were no intra-operative technical failures of the anastomosis or deaths.

Five patients had strictures
