Gastric interposition following transhiatal esophagectomy: radiographic evaluation

Gastric interposition was achieved in 138 patients following transhiatal esophagectomy without thoracotomy. Among these, 33 had benign and 105 malignant lesions. All patients were evaluated on the 10th postoperative day with a barium swallow examination. However, if an anastomotic leak was suspected clinically before this time, a water-soluble contrast study was initially obtained. Early postoperative complications included anastomotic leaks (15), cricopharyngeal incoordination with aspiration (6), and gastric perforation (2). Late postoperative complications included anastomotic strictures (12), pyloric stenosis (4), recurrence of tumor (3), and transhiatal visceral herniation (2). Our technique of postoperative radiographic evaluation, particularly when a leak is suspected clinically, is discussed.     

Diaphragmatic herniation after transhiatal esophagectomy.

Increasing experience with transhiatal esophagectomy (THE) has brought with it a good understanding of the advantages and disadvantages of the technique. As in our case, diaphragmatic hernias after THE may result from excess manipulation and extension of the hiatus during surgery. The varying nature of the clinical presentation may cause delay in diagnosis. We report our case and discuss how to diagnose and manage this complication under the sum of cases reported previously in English literature.     

Perioperative outcomes of esophagectomy preceded by the laparoscopic transhiatal approach for esophageal cancer

This study was designed to determine the efficacy of esophagectomy preceded by the laparoscopic transhiatal approach (LTHA) with regard to the perioperative outcomes of esophageal cancer. The esophageal hiatus was opened by hand‐assisted laparoscopic surgery, and carbon dioxide was introduced into the mediastinum. Dissection of the distal esophagus was performed up to the level of the tracheal bifurcation. En bloc dissection of the posterior mediastinal lymph nodes was performed using LTHA. Next, cervical lymphadenectomy, reconstruction via a retrosternal route with a gastric tube and anastomosis from a cervical approach were performed. Finally, a small thoracotomy (around 10 cm in size) was made to extract the thoracic esophagus and allow upper mediastinal lymphadenectomy to be performed. The treatment outcomes of 27 esophageal cancer patients who underwent LTHA‐preceding esophagectomy were compared with those of 33 patients who underwent the transthoracic approach preceding esophagectomy without LTHA (thoracotomy; around 20 cm in size). The intrathoracic operative time and operative bleeding were significantly decreased by LTHA. The total operative time did not differ between the two groups, suggesting that the abdominal procedure was longer in the LTHA group. The number of resected lymph nodes did not differ between the two groups. Postoperative respiratory complications occurred in 18.5% of patients treated with LTHA and 30.3% of those treated without it. The increase in the number of peripheral white blood cells and the duration of thoracic drainage were significantly decreased by this method. Our surgical procedure provides a good surgical view of the posterior mediastinum, markedly shortens the intrathoracic operative time, and decreases the operative bleeding without increasing major postoperative complications.     

Herniation of colon following transhiatal esophagectomy.

We report a 38-year-old man with intestinal obstruction following transhiatal esophagectomy for carcinoma esophagus; it occurred secondary to herniation of the transverse colon through the esophageal hiatus into the mediastinum. The patient is asymptomatic after reduction of the hernia and repair of the disphragmatic hernia.     

Laparoscopic transhiatal resection of epiphrenic diverticulum

Our experience with videolaparoscopic operations for hiatus hernia and achalasia, which have almost replaced classical procedures, enabled us to use the same technique for other interventions in the distal third of the thoracic esophagus. Thus, we were able to treat epiphrenic diverticulum using a minimally invasive approach. We report our experience with videolaparoscopic diverticulum resection. The procedure was performed in three patients, all of them elderly men with ventilation limitation and a history of a chest intervention. The procedure included myotomy and an antireflux procedure. No significant complications occurred during the operations or postoperative periods; a minor leak that was successfully managed conservatively occurred in one patient. We conclude that videolaparoscopy could be a possible alternative to the standard classical left-side thoracotomy approach for patients in whom a classical operation is not feasible.     

Early colonic transhiatal herniation and anastomotic leak after Ivor Lewis esophagectomy

Transhiatal herniation of the abdominal organs is a rare complication after esophagectomy. Surgical treatment is usually mandatory because of the high mortality associated with this condition. We present a case of colonic herniation that could contribute to failure of the esophagogastric anastomosis. Repair of both problems was performed through a right posterior thoracotomy.     

Laparoscopic transhiatal resection of giant epiphrenic esophageal diverticulum

Epiphrenic diverticula are rare. Their true incidence is unknown. Thoracotomy or thoracoscopy with resection and myotomy is the most common reported approach for the surgical treatment of epiphrenic esophageal diverticula. In patients with large epiphrenic diverticula, the laparoscopic approach is an uncommon procedure. In this case, the laparoscopic transhiatal approach was shown to be safe and effective over with short-term follow-up. However, long-term follow-up of this procedure is needed.     

Simultaneous transhiatal esophagectomy and coronary artery bypass grafting without cardiopulmonary bypass

A 69-year-old patient underwent simultaneous transhiatal esophagectomy for carcinoma of the esophagogastric junction and benign spindle cell gastric tumor and coronary artery bypass grafting without cardiopulmonary bypass. A standard technique of transhiatal esophagectomy was used. The long saphenous vein was grafted to the left anterior descending artery and to the distal circumflex artery. The total theatre time was 6.5 h and the total ischemic time was 19 min. The patient made a good recovery and was discharged on day 18. He is enjoying an active lifestyle 6 months post-operatively.     

Laparoscopic inversion esophagectomy: simplifying a daunting operation

Minimally invasive esophageal resection is a technically demanding procedure that may reduce patient morbidity and improve convalescence when compared with the open approach. Despite these proposed advantages, the minimally invasive approach has not been widely embraced and is routinely performed in only a few specialized centers around the world. The laparoscopic inversion esophagectomy attempts to eliminate some of the technical obstacles inherent in this procedure by simplifying the transhiatal mediastinal dissection, facilitating vagal preservation, and enhancing safety. We present a case of a 37-year-old man who underwent laparoscopic inversion esophagectomy for Barrett's esophagus with high-grade dysplasia. Immediate and long-term outcome measures are being prospectively gathered in order to establish the ultimate value of this procedure.     

Tumor seeding of the jejunostomy site after transhiatal esophagectomy for esophageal carcinoma

A 65-year-old male patient with squamous cell carcinoma of the esophagus had a transhiatal esophagectomy after a prophylactic tube jejunostomy. The tube was removed 3 weeks after surgery. Ten months later, a painless 2-cm abdominal mass was noted at the previous jejunostomy site. Subsequent segmental resection of the jejunum disclosed metastatic squamous cell carcinoma of the esophagus. It is possible that tumor seeding may develop at the jejunostomy site after transhiatal esophagectomy for esophageal carcinoma.     

Impact of gastric tube diameter on upper mediastinal anatomy after transhiatal esophagectomy

The most common means of reconstructing the esophagus in patients undergoing transhiatal esophagectomy is by passing the stomach through the esophageal bed into the neck, where an esophagogastric anastomosis is fashioned. A number of factors need to be considered in mobilizing the stomach for transhiatal esophageal reconstruction: the stomach tube must have adequate blood supply and be wide enough to permit passage of solid food and yet narrow enough to facilitate emptying and to fit through the limited space of the upper mediastinum. The construction of a non-reversed, greater curvature gastric tube of approximately 4-5 cm diameter, supplied by the right gastroepiploic vessels, appears to accomplish all of these goals.     

Radical minimally invasive esophagectomy for esophageal cancer via transcervical and transhiatal approaches: a narrative review

ObjectiveMinimally invasive esophagectomy (MIE) has been widely applied for the treatment of esophageal carcinoma. It is much less invasive, as it avoids employing a transthoracic procedure.BackgroundMIE via transcervical and transhiatal approaches has been adopted in our center. In this approach, with the assistance of single-port techniques or robotic-assisted surgical systems, the esophagus is mobilized under visualization, which is followed by the removal of esophageal and mediastinal lymph nodes.MethodsIncreasing the surgical space by mediastinal insufflation or by elevation of the sternum with a hook may improve intraoperative identification of tissues and facilitate intraoperative mobilizations. The procedure can be performed simultaneously via both cervical and abdominal approaches without the need for intraoperative turning of the patient, which shortens the operative time. Also, there is no need for thoracotomy or single-lung ventilation, which avoids disturbance to the respiratory and circulation systems.ConclusionsSuitable instruments, especially state-of-the-art energy instruments, facilitate surgical separation and hemostasis. This surgical procedure has become increasingly sophisticated over the past decade, and its modular operation has been widely recognized. The feasible place of the neck-esophageal hiatus rendezvous is on the left main bronchus around the subcarinal region. Here we describe the technical features, key steps, and necessary precautions of this minimally invasive surgery for esophageal carcinoma.     

Efficacy of mediastinal lymphadenectomy in transhiatal esophagectomy with and without diaphragm opening: a cadaveric study

Transhiatal esophagectomy (THE) is believed to induce a lower morbidity and mortality compared with transthoracic esophagectomy, but to be inefficient in performing mediastinal lymphadenectomy. Some surgeons are convinced that lymphadenectomy of the lower mediastinum in THE and transthoracic esophagectomy are equivalent. To test this, the authors performed THE in 20 cadavers (10 with and 10 without diaphragm opening). The number of lymph nodes resected with the esophagus and dissected through the hiatus was counted. After THE, the thorax was opened and the number of residual lymph nodes was evaluated. Complications were also assessed. The results show that lymphadenectomy in THE is incomplete in the lower mediastinum and not possible in the upper mediastinum; comparing THE with and without diaphragm opening, the first permits resection of a superior number of lymph nodes with the esophagus and dissection of a higher number of nodes through the hiatus. It is concluded that THE does not provide an effective mediastinal lymphadenectomy.     

Prospective comparison of transthoracic versus transhiatal esophagectomy following neoadjuvant therapy for esophageal cancer

Transthoracic esophagectomy (TT) has been championed as a better cancer operation than transhiatal esophagectomy (TH) because the approach facilitates meticulous wide tumor excision and lymphadenectomy. However, neoadjuvant chemoradiotherapy (CRTS) and chemotherapy (CS) have been reported to improve outcomes, and we aimed to compare outcomes after multimodal therapy related to the operative approach. One hundred and fifty-one consecutive patients were studied prospectively. All patients were staged with computed tomography and endoluminal ultrasound, and treatment decisions were related to stage and performance status. One hundred and nineteen TT (median age 58 years, 92 male, 54 CRTS, 65 CS) were performed compared to 32 TH (median age 57 year, 27 male, 14 CRTS, 18 CS). Primary outcome measure was survival. Post-operative morbidity and mortality were 54% and 4%, respectively, after TT compared with 59% and 6% after TH (chi2 0.239 df 1, P=0.625). Recurrent cancer was no less frequent after TT (52%) than after TH (37.5%, chi2 2.151 df=1, P=0.142). Cumulative uncorrected 5-year survival was 34% after TT compared with 53% after TH (log rank 1.44, df=1, P=0.2298). Median survival was also similar in lymph node positive patients (TT vs. TH, 23 months vs. 22 months, respectively, log rank 0.25, df=1, P=0.6199). Despite the fact that patients receiving multimodal therapy and a TH esophagectomy were less fit, operative morbidity, mortality and recurrence were similar, and survival did not differ significantly when compared with multimodal TT esophagectomy.     

Results of transhiatal esophagectomy in cancer of the esophagus and other diseases.

We present the results we obtained during the last 12 years with transhiatal esophagectomy. Two hundred and eighty-three patients were operated on using this procedure; 171 of them underwent the operation for cancer of the esophagus, 73 for cancer of the cardia, and 11 for cancer of the hypopharynx. The tumor stage, the operative technique, and the type of esophageal replacement (stomach: 62.9%; colon: 37.1%) are described. Overall operative mortality was 5.6%, mainly as a result of respiratory insufficiency. Long-term survival was 11.9% at five years for cancer of the esophagus, much lower than the 48.3% for cancer of the cardia.     

Ivor Lewis approach is superior to transhiatal approach in retrieval of lymph nodes at esophagectomy

SUMMARY.  Lymph node involvement may impact postoperative therapeutic decision-making and prognosis in patients undergoing esophagectomy. This study evaluates which surgical approach yields the most lymph nodes. We undertook a retrospective chart review of esophagectomies performed by six surgeons from April 1994 to February 2004 using a prospective general thoracic surgery database at Mayo Clinic, Rochester, Minnesota, US. Lymph nodes were categorized into one of 17 regions per the American Joint Committee on Cancer, with the total number of lymph nodes, summed over each region, used as the primary outcome. A total of 517 esophagectomies were performed: 68 transhiatal, 392 Ivor Lewis, and 57 extended Ivor Lewis. A mean of 18.7 (SD 8.5) lymph nodes were retrieved with the Ivor Lewis approach as compared to 17.4 (SD 9.2) with the extended Ivor Lewis approach ( P  = 0.30). Since there was no statistical difference between the number of nodes collected in either Ivor Lewis approach, they were collapsed into one group for comparison with the transhiatal cases. Significantly more lymph nodes were collected with an Ivor Lewis approach (mean 18.5, SD 8.6) than with a transhiatal approach (mean 9.0, SD 5.0, P  < 0.001). As expected, more thoracic lymph nodes were retrieved with the Ivor Lewis approach [mean 12.4 (SD 7.0) vs. 4.7 (SD 5.3), P  < 0.001]. The Ivor Lewis approach was also superior for retrieval of abdominal nodes [mean 6.1 (SD 5.6) versus 4.3 (SD 4.4), P  = 0.01]. More lymph nodes are obtained at esophagectomy with an Ivor Lewis than a transhiatal approach.     

Robot‐assisted transhiatal esophagectomy: a 3‐year single‐center experience

Minimally invasive esophagectomy has emerged as an important procedure for disease management in esophageal cancer (EC) with clear margin status, less morbidity, and shorter hospital stays compared with open procedures. The experience with transhiatal approach robotic esophagectomy (RE) for dissection of thoracic esophagus and associated morbidity is described here. Between March 2007 and November 2010, 40 patients with resectable esophageal indications underwent transhiatal RE at the institute. Clinical data for all patients were collected prospectively. Of 40 patients undergoing RE, one patient had an extensive benign stricture, one had high‐grade dysplasia, and 38 had EC. Five patients were converted from robotic to open. Median operative time and estimated blood loss were 311 minutes and 97.2 mL, respectively. Median intensive care unit stay was 1 day (range, 0–16), and median length of hospital stay was 9 days (range, 6–36). Postoperative complications frequently observed were anastomotic stricture (n= 27), recurrent laryngeal nerve paresis (n= 14), anastomotic leak (n= 10), pneumonia (n= 8), and pleural effusion (n= 18). Incidence rates of laryngeal nerve paresis (35%) and leak rate (25%) were somewhat higher in comparison with that reported in literature. However, all vocal cord injuries were temporary, and all leaks healed following opening of the cervical incision and drainage. None of the patients died in the hospital, and 30‐day mortality was 2.5% (1/40). Median number of lymph nodes removed was 20 (range, 3–38). In 33 patients with known lymph node locations, median of four (range, 0–12) nodes was obtained from the mediastinum, and median of 15 (range, 1–26) was obtained from the abdomen. R0 resection was achieved in 94.7% of patients. At the end of the follow‐up period, 25 patients were alive, 13 were deceased, and 2 patients were lost to follow‐up. For patients with EC, median disease‐free survival was 20 months (range, 3–45). Transhiatal RE, by experience, is a feasible albeit evolving oncologic operation with low hospital mortality. The benefits include minimally invasive mediastinal dissection without thoracotomy or thoracoscopy. A reasonable operative time with minimal blood loss and postoperative morbidity can be achieved, in spite of the technically demanding nature of the procedure. Broader use of this technology in a setting of high‐volume comprehensive surgical programs will almost certainly reduce the complication rates. Robotic tanshiatal esophagectomy with the elimination of a thoracic approach should be considered an option for the appropriate patient population in a comprehensive esophageal program.     

Laparoscopic pancreatectomy: Indications and outcomes

The application of minimally invasive approaches to pancreatic resection for benign and malignant diseases has been growing in the last two decades. Studies have demonstrated that laparoscopic distal pancreatectomy(LDP) is feasible and safe, and many of them show that compared to open distal pancreatectomy, LDP has decreased blood loss and length of hospital stay, and equivalent post-operative complication rates and shortterm oncologic outcomes. LDP is becoming the procedure of choice for benign or small low-grade malignant lesions in the distal pancreas. Minimally invasive pancreaticoduodenectomy(MIPD) has not yet been widely adopted. There is no clear evidence in favor of MIPD over open pancreaticoduodenectomy in operative time, blood loss, length of stay or rate of complications. Robotic surgery has recently been applied to pancreatectomy, and many of the advantages of laparoscopy over open surgery have been observed in robotic surgery. Laparoscopic enucleation is considered safe for patients with small, benign or low-grade malignant lesions of the pancreas that is amenable to parenchyma-preserving procedure. As surgeons’ experience with advanced laparoscopic and robotic skills has been growing around the world, new innovations and breakthrough in minimally invasive pancreatic procedures will evolve.
