Minimally invasive esophagectomy for caustic esophageal stricture in children

Esophageal stricture after lye ingestion in children is the most frequent indication for esophagectomy in children, but this operation entails significant risks for complications. With continuing advances in minimally invasive technology, complex procedures such as esophagectomy can be performed using small incisions, with the aim of reducing morbidity and mortality. Experience with minimally invasive esophagectomy is limited and has involved thoracoscopic dissection with the addition of laparotomy for gastric mobilization. The authors report a case of intractable caustic esophageal stricture in a child treated by a totally minimally invasive esophagectomy through a combined thoracoscopic and laparoscopic approach. In adult patients, this procedure has been associated with decreased hospital stay and more rapid return to normal activities, and we believe similar benefits will be obtained in children. Until further studies are done to show the advantage over the standard open technique, this procedure should be performed only in centers with experience in open esophageal surgery in children as well as by surgeons with advanced thoracoscopic and laparoscopic skills.     

Extent of lymphnode dissection with minimally invasive esophageal resection

Esophageal resection is still today associated with a high morbidity and mortality. Minimally invasive procedures show a significantly lower rate of such complications and therefore might also be associated with a lower surgical risk. However, publications till date contain little or no data on the extent of lymph node dissection. The aim of our study was to evaluate the morbidity and mortality rate of minimally invasive esophageal resection. MATERIAL AND METHODS: In the last two years, we carried out 25 minimally invasive esophageal resections on five women and 20 men with a median age of 63 years (range 41-74 years). All data were accrued prospectively. RESULTS: Nine patients were operated upon transhiatally and 12 combined laparocopic-thoracoscopic. On four patients, a thoracotomy was necessary. The average surgical time for the transhiatal approach was calculated at 164 minutes (range 150-180 min) and for the combined laparoscopic-thoracoscopic procedure 285 minutes (240-360 min). The thoracoscopic esophageal resection itself lasted 105 minutes on average; the last five resections each lasting 70 minutes. A median of 24,5 lymph nodes (19-26) was calculated in the laparoscopic-thoracoscopic technique. The transhiatal procedure revealed a median of 14 lymph nodes (12-17). Postoperatively, we had three cases of anastomotic and two cases of bronchial leakages, most probably associated with the use of monopolar current; complications no longer seen since usage of the HARMONIC ACE for surgical preparation. There was no 30 day letality. CONCLUSION: Our experience with 25 successful minimally invasive esophageal resections shows that with increasing experience and better surgical equipment, the extent of lymph node dissection does not differ from open procedure.

Minimally invasive surgery for esophageal epiphrenic diverticulum: the results of 133 patients in 25 published series and our experience

Esophageal epiphrenic diverticula are uncommon. Traditionally, thoracotomy has been the preferred surgical approach. Recently, minimally invasive approaches have been reported in a few series. However, the best surgical approach remains uncertain. In this study, we review the results of 25 articles discussing laparoscopic or thoracoscopic surgery. From January 1995 to December 2008, there were a total of 133 patients reported in English-language journals in PubMed. Nineteen patients (14 %) underwent thoracoscopic surgery, 112 (84 %) laparoscopic surgery and two patients (2 %) were treated using a combination approach. The diverticulectomy was performed using an endostapler device in all patients. A myotomy was added in 103 patients (83 %). A fundoplication was added in 106 patients (85 %). There were two deaths during surgery (2 %). The post-operative morbidity rate was 21 %. The most severe complication was suture-line leakage, which occurred in 20 patients (15 %). Recently, we successfully treated a patient with an epiphrenic esophageal diverticulum by performing a minimally invasive laparoscopic transhiatal resection and Heller myotomy with Dor fundoplication after observing its enlargement on radiological and endoscopic examinations over 2 years. We believe laparoscopic transhiatal resection and Heller myotomy with Dor fundoplication may therefore become the standard treatment modality for minimally invasive surgery for esophageal epiphrenic diverticulum.     

Thoracoscopic and laparoscopic esophagectomy: initial experience and outcomes

Background: Although surgical resection currently is the preferred treatment for fit patients with resectable esophageal cancers, it is associated with a relatively high risk of morbidity and significant perioperative mortality. Currently, a range of open surgical approaches are used. More recently, minimally invasive approaches have become feasible, with the potential to reduce perioperative morbidity. This study investigated the outcomes from one such approach. Methods: Outcome data were collected prospectively for 36 consecutive patients who underwent a minimally invasive esophagectomy for esophageal cancer. A three-stage approach was used, with all the patients undergoing a thoracoscopic esophageal mobilization, combined with either open or hand-assisted laparoscopic abdominal gastric mobilization, and open cervical anastomosis. An open abdominal approach was used for 15 of the patients and a hand-assisted laparoscopic approach for 21. A total of 34 patients had invasive malignancy, whereas 2 had preinvasive disease. A group of 23 patients (68%) who had invasive malignancies also received neoadjuvant chemotherapy and radiotherapy. Results: The mean operating time ranged from 190 to 360 min (mean, 263 min). The median postoperative hospital stay was 16 days. In-hospital mortality was 5.5% (2/36), and perioperative morbidity was 41%. The perioperative outcomes for patients undergoing an open abdominal approach and those who had hand-assisted laparoscopic surgery were similar. For the patients who underwent a hand-assisted laparoscopic abdominal procedure, the total operating time was shorter (248 vs 281 min), and the blood loss was less (223 vs 440 ml). The median follow-up period was 30 months. The 4-year survival predicted by Kaplan–Meir for the 34 patients with invasive malignancy was 44%. Conclusion: The outcome for esophagectomy using thoracoscopic esophageal mobilization, with or without hand-assisted laparoscopic abdominal surgery, was comparable with data from conventional open surgical approaches. These approaches can be performed with an acceptable level of perioperative morbidity. Further application of these techniques, with close scrutiny of outcome data, is appropriate.     

Surgery of esophageal cancer

Background

Surgery is the only option for curative treatment in patients with esophageal carcinoma. Despite the debates related to the peri-operative therapy regime, a generally accepted consensus on surgical approach is not reached yet. The debate focuses mainly on pros and cons between radical transthoracic resection and the (limited) transhiatal resection in the last decade.

Methods

The PubMed database was searched for randomized trials, meta-analyses, and retrospective single-center studies. The search terms were “esophageal carcinoma,” “esophageal junction carcinomas,” “transhiatal,” “transthoracic,” “morbidity,” “mortality,” and “surgery.”

Results

The radical transthoracic approach should be the standard of care for esophageal carcinoma since it does not go along with an increased risk of postoperative morbidity or mortality but reveals an improved survival. Patient-related co-morbidities are the most influencing factors for the postoperative outcome. For type II esophageal junction carcinoma, treatment options from transhiatal extended gastrectomy to esophagectomy with hemigastrectomy or esophagogastrectomy with colonic interposition are existing. In type III esophagogastric junction carcinomas, the transhiatal extended gastrectomy is the standard of care, and the minimally invasive approach should be performed in specialized centers.

Conclusion

Based on current available study results, this expert review provides a decision support for the best surgical strategy depending on tumor localization and patients’ characteristics.     

Open transthoracic or transhiatal esophagectomy versus minimally invasive esophagectomy in terms of morbidity, mortality and survival

Background Surgical treatment of esophageal cancer is associated with a high rate of morbidity and mortality even in specialized centers. Minimally invasive surgery has been proposed to decrease these complications. Methods The authors present their results regarding postoperative complications and the survival rate at 3 years, comparing the classic open procedures (transthoracic or transhiatal esophagectomy) with minimally invasive surgery. Surgical procedures were performed according to procedures published elsewhere. Results The study enrolled 166 patients who underwent surgery between 1990 and 2003. Open transthoracic surgery was performed for 60 patients. In this group of patients, postoperative mortality was observed in 11% of the cases. Major, minor, and late complications were observed in 61.6% of the patients, and the 3-year survival rate was 30% for this group. Open transhiatal surgery was performed for 59 patients. The morbidity, mortality, and 3-year rate were almost the same as for the transthoracic surgery group. For the 47 patients submitted to minimally invasive procedures (thoracoscopic and laparoscopic), the complications and mortality rates were significantly reduced (38.2% and 6.4%, respectively). For the patients submitted to minimally invasive surgery, the 3-year survival rate was 45.4%. It is important to clarify that the patients submitted to minimally invasive surgery manifested early stages of the diseases, and that this the reason why the morbimortality and survival rates were better. Conclusions The transthoracic and transhiatal open approaches have similar early and late results. Minimally invasive surgery is an option for patients with esophageal carcinoma, with reported results similar to those for open surgery. This approach is indicated mainly for selected patients with early stages of the disease.

Evidenzlage zur minimalinvasiven Chirurgie beim Ösophaguskarzinom

Surgery remains the mainstay of potentially curative treatment of esophageal cancer; however, esophageal resection is still associated with a relevant morbidity and mortality. Furthermore, patients frequently suffer from concomitant comorbidities and present in a reduced nutritional status. The rationale of minimally invasive surgery is the reduction of surgical trauma with subsequent minimization of (pulmonary) complications and mortality without compromising oncological quality. Minimally invasive esophageal resection was established nearly two decades ago and since then some centers worldwide have adopted this approach as the preferred option for surgical treatment of esophageal cancer. Minimally invasive esophageal resection can be safely performed and provides excellent results in experienced hands. Currently, there is only one randomized trial available comparing open and minimally invasive resection. It was demonstrated that the latter significantly reduced pulmonary complications with comparable mortality and oncological outcome. However, in the majority of studies these convincing results could not be confirmed. Reduced blood loss and a shortened hospital stay were shown to be the main advantages of the minimally invasive approach. Due to technical modifications, patient selection and a remarkable heterogeneity of current studies, a final conclusion on the value of minimally invasive esophagectomy is difficult to be drawn. Based on the current evidence, a noncritical use of minimally invasive resection for esophageal cancer cannot be recommended; however, in selected patients and with appropriate expertise this approach is at least comparable to open esophagectomy.     

Minimally invasive management of epiphrenic esophageal diverticula

The purpose of this study is to review our initial experience with a minimally invasive approach to manage symptomatic epiphrenic esophageal diverticula. Five patients with symptomatic epiphrenic esophageal diverticula underwent surgical management between August 1997 and December 2002. All patients complained of dysphagia; had experienced symptoms for at least 12 months; and were evaluated preoperatively by a barium esophagram, esophagogastroduodenoscopy, and esophageal manometry. The epiphrenic esophageal diverticula measured 5 cm or less in all patients. Manometry demonstrated esophageal dysmotility in three patients. A minimally invasive technique was completed in all five patients. Four patients underwent laparoscopic diverticulectomy and myotomy including a concomitant Toupet fundoplication, and one patient underwent thoracoscopic diverticulectomy and myotomy. The mean operative time was 245 minutes (range 175-334). The longest operative time was for the thoracoscopic procedure. The estimated blood loss was minimal (range 30-100 cm3). The laparoscopic patients had a mean postoperative length of stay of 2.75 days (range 2-4) and the patient undergoing a thoracoscopic approach was discharged on postoperative day 6 due to a history of lung disease and home oxygen requirements. There were no other postoperative complications. After a mean follow-up of 16.2 months (range 3-36) all patients are asymptomatic. Short-term follow-up after our initial experience with minimally invasive approaches for epiphrenic esophageal diverticula demonstrates that thoracoscopic and laparoscopic approaches are feasible; safe; and effectively alleviate dysphagia, regurgitation, and other associated symptoms. Long-term outcomes should be monitored during the evolution of these novel minimally invasive techniques to ensure outcomes comparable to those of a transthoracic open approach.     

Thoracoscopic and laparoscopic esophagectomy for benign and malignant disease: lessons learned from 46 consecutive procedures

BACKGROUND: Transhiatal and transthoracic esophagectomy are common approaches for esophageal resection. The literature is limited regarding the combined thoracoscopic and laparoscopic approach to esophagectomy. The aim of this study was to evaluate the outcomes of combined thoracoscopic and laparoscopic esophagectomy for the treatment of benign and malignant esophageal disease. STUDY DESIGN: We performed a retrospective chart review of 46 consecutive minimally invasive esophagectomies performed between August 1998 and September 2002. Indications for esophagectomy were carcinoma (n = 38), Barrett's esophagus with high-grade dysplasia (n = 3), and recalcitrant stricture (n = 5). Of 38 patients with carcinoma 23 (61%) had neoadjuvant therapy. The main outcome measures were operative time, blood loss, length of intensive care unit and hospital stay, conversion rate, morbidity, mortality, pathology, disease recurrence, and survival. RESULTS: Approaches to esophagectomy were thoracoscopic and laparoscopic esophagectomy (n = 41), thoracoscopic and laparoscopic Ivor Lewis resection (n = 3), abdominal only laparoscopic esophagogastrectomy (n = 1), and hand-assisted laparoscopic transhiatal esophagectomy (n = 1). Minimally invasive esophagectomy was successfully completed in 45 (97.8%) of 46 patients. The mean operative time was 350 +/- 75 minutes and the mean blood loss was 279 +/- 184 mL. The median length of intensive care unit stay was 2 days and median length of stay was 8 days. Major complications occurred in 17.4% of patients and minor complications occurred in 10.8%. Late complications were seen in 26.1% of patients. The overall mortality was 4.3%. Among the 38 patients who underwent esophagectomy for cancer the 3-year survival was 57%. In a mean followup of 26 months there was no trocar site or neck wound recurrences. CONCLUSIONS: A thoracoscopic and laparoscopic approach to esophagectomy is technically feasible and safe for the treatment of benign and malignant esophageal disease. With a mean followup of 26 months thoracoscopic and laparoscopic esophagectomy appears to be an oncologically acceptable surgical approach for the treatment of esophageal cancer.     

Minimally invasive esophageal resection

Esophagus resection is the adequate treatment for some benign esophageal diseases, especially caustic and peptic stenosis and end-stage motility dysfunction. However, the most frequent indications for esophageal resection are the high-grade dysplasia of Barrett esophagus and nonmetastasized esophageal cancer. Different procedures have been developed to perform esophageal resection given the 5-year survival rate among operated patients of only 18%. The disadvantage of the conventional approach is the high morbidity rate, especially with pulmonary complications. Minimally invasive esophageal resections, which were first performed in 1991, may reduce this important morbidity and preserve the oncologic outcome. The first reports of morbidity and respiratory complications with this approach were discouraging and it seemed likely that the procedure would have to be abandoned. However, in the last 5 years, an important impetus for these techniques was given by Japanese groups and the group of Luketich in Pittsburgh. The outcomes of these new series are different than those of the beginning period, leading to an enormous expansion worldwide. Important factors for this change are the standardization of the operative technique, the experience of many surgeons with more advanced laparoscopic procedures, important improvements in instruments for dissection and division of tissues, a better anesthesia technique, and a better selection of patients for operation. Two minimally invasive techniques are being perfected: the three-stage operation by right thoracoscopy and laparoscopy, and the transhiatal laparoscopic approach. It seems that the first approach may be applied successfully for any tumor in the esophagus, whereas the transhiatal seems ideal for distal esophageal and esophagogastric junction tumors. This review paper discusses all these aspects, with special attention for indications and operative technique.     

Video-assisted esophagectomy for esophageal cancer

Video-assisted surgery for esophageal cancer is an advanced surgical technique. It has been developed on the basis of the concept of minimally invasive surgery. Given that there are several options regarding the operative procedures for thoracic esophageal cancer, several laparoscopic approaches have been proposed. The first video-assisted thoracoscopic esophagectomy through a right thoracoscopic approach and the first transhiatal esophagectomy were reported in the early 1990s. A mediastinoscope-assisted esophagectomy has also been reported as a substitute for a blunt dissection of the esophagus. Moreover, a video-assisted Ivor-Lewis esophagectomy by right thoracotomy with intrathoracic anastomosis has also been performed. Furthermore, laparoscopic gastric mobilization and gastroplasty are also widely accepted substitutions for open laparotomy. This article reviews the literature on the laparoscopic approaches for esophageal cancer.     

Minimally invasive Ivor Lewis esophagectomy

Ivor Lewis esophagectomy consists of a laparotomy and right thoracotomy for resection of the intrathoracic esophagus. Recent advances in minimally invasive surgical technology have allowed surgeons to apply laparoscopy and thoracoscopy to perform esophagectomy. However, there have been few reports that describe a totally minimally invasive Ivor Lewis esophagectomy. We present a case of combined laparoscopic and thoracoscopic resection of the distal third esophagus with an intrathoracic esophagogastric reconstruction for esophageal carcinoma.     

Open Versus Minimally Invasive Esophagectomy: What Is the Best Approach? Frame the Issue

Surgical resection continues to be the gold standard treatment approach for early invasive and locoregional esophageal cancer. Esophagectomy has historically had a reputation as a complex operation with high mortality and morbidity. Increasingly, results from high-volume specialized centers have demonstrated that mortality rates of below 4% should be expected and that patients can potentially demonstrate excellent levels of quality of life following surgical resection. Up until recently, virtually all surgical resections were done utilizing an open approach utilizing either a transthoracic or a transhiatal operation. Over the past several years, however, a variety of fully minimally invasive or hybrid procedures have been advocated with a view of improving mortality and morbidity outcomes. In the absence of either randomized or controlled prospective comparisons, this series of papers will review current perceptions of the advantages of both minimally invasive and open surgery for the treatment of esophageal cancer.

Thoracoscopic and laparoscopic esophagectomy

Esophagectomy is both complex and challenging, and it may be associated with significant morbidity and mortality. With improvements in instrumentation and increasing experience with laparoscopic and thoracoscopic techniques, minimally invasive approaches to esophagectomy are being explored to determine feasibility, results, and potential advantages. Most of this experience has been with case studies or small series, with many surgeons using thoracoscopy in combination with standard laparotomy. Many of the patients have been carefully selected for these procedures because they have small tumors or high-grade dysplasia. Our technique for esophagectomy has evolved from a laparoscopic transhiatal approach to a combined laparoscopic and thoracoscopic approach. Our experience with this procedure has increased, and now we offer this approach to the majority of patients with resectable cancers. We review our operative technique and the results of surgery in our first 50 patients who underwent minimally invasive esophagectomy for cancer or high-grade dysplasia.     

The emerging role of minimally invasive surgical techniques for the treatment of lung malignancy in the elderly

As a consequence of the general aging of the population, improved diagnostic techniques, and preoperative interventions to enhance the efficacy of surgical therapy, increasing numbers of elderly patients are presenting for pulmonary resection. Clear association between advanced age and the perioperative morbidity and mortality associated with lung cancer surgery has generated considerable interest in applying minimally invasive operative techniques in the geriatric population under the belief that this approach will improve outcome. This review examines the available data regarding video-assisted thoracoscopic lobectomy and concludes that this technique for the surgical treatment of early-stage lung cancer may parallel conventional thoracotomy in terms of oncologic efficacy while decreasing perioperative morbidity in the elderly.     

Minimally invasive esophagectomy: early experience and outcomes

Minimally invasive esophageal surgery has the potential to improve mortality, hospital stay, and functional outcomes when compared with open methods. Although technically complex, combined laparoscopic and thoracoscopic esophageal resection is feasible. A case series of 20 patients who underwent minimally invasive total esophagectomy is presented. This study was a review of a prospective database. The purpose was to evaluate early results with laparoscopic total esophagectomy for benign and malignant disease. Between January 2003 and November 2005, 20 patients underwent minimally invasive esophageal surgery. All operations were performed by the same two surgeons. Age, gender, indications for surgery, pathologic stage, operative time, blood loss, transfusion requirements, intensive care unit length of stay, hospital length of stay, postoperative complications, and mortality were recorded. Diet progression, dysphagia, and need for stricture management were also recorded. Of the 20 minimally invasive total esophagectomies performed, 18 (90%) were completed successfully. The average age of the patients was 53 years. Indications for surgery were malignancy (n = 13), carcinoma in situ in the setting of Barrett's esophagus (n = 2), and benign stricture (n = 3). The average operating time was 467 minutes (range 346-580 min). Median blood loss was 350 mL (range 150-500 mL). The median intensive care unit stay was 2 days, and the median hospital length of stay was 12 days. Pathology revealed that 7 per cent of patients had stage I disease, 27 per cent of patients had stage II disease, and 53 per cent of patients had stage III disease. There was a single mortality (5%), a cervical leak in two patients (10%), a gastric tip necrosis in one patient (5%), and tracheoesophageal fistula in one patient (5%). Major complications occurred in eight patients (40%) and minor complications in nine (50%). Thirteen (72%) patients were discharged on enteral tube feeds to supplement caloric intake. The application of minimally invasive techniques in the arena of esophageal surgery continues to evolve. This approach has the potential to improve mortality, hospital stay, and other outcomes when compared with open methods. Although technically complex, laparoscopic total esophagectomy is feasible.
