Laparoscopic transhiatal esophagectomy at a low-volume center

Background and Objectives:

Surgical treatment of esophageal cancer is associated with a high rate of morbidity, even in specialized centers. Minimally invasive esophageal resection has become increasingly feasible and is gaining popularity in some high-volume institutions. This study assesses the short-term outcomes of laparoscopic transhiatal esophagectomy performed by a single surgeon at a single low-volume institution over a 20-month period.

Methods:

Over the study period, 16 patients underwent laparoscopic transhiatal esophagectomy. All patients were men with an average age of 70 years (range, 50 to 81).

Results:

Two patients required intraoperative conversion to alternative surgical techniques, 1 to an Ivor-Lewis esophagectomy and 1 to an open transhiatal approach. Average operative time was 198 minutes (range, 147 to 303). Mean hospital stay was 16.7 days (range, 9 to 30). The average number of resected lymph nodes was 11.7, and 2 patients had benign pathology. No deaths occurred in the 30-day postoperative period.

Conclusion:

Laparoscopic transhiatal esophagectomy is an advanced laparoscopic procedure that can be performed with equivalent morbidity and mortality by a low-volume surgeon in a low-volume center with results comparable to those of high-volume centers. While several authors have demonstrated a correlation between lower mortality rates and high-volume esophagectomy hospitals, our results support surgeon experience as more important than the absolute number of procedures performed each year.     

Laparoscopic transhiatal esophagectomy for esophageal cancer

BACKGROUND: Traditional esophagectomy may be associated with mortality, considerable morbidity, and lengthy recovery. It is often performed in cancer patients who are typically older, have associated comorbidities, and are often malnourished, all factors that increase surgical risk. Minimally invasive esophagectomy has the potential advantages of being a less traumatic procedure with an easier postoperative recovery and fewer wound and pulmonary complications. METHODS: A retrospective analysis of patients who underwent laparoscopic transhiatal esophagectomy was performed. Assessed parameters included patient demographics and operative data, pathology results, and long-term follow-up of at least 12 months. RESULTS: Twenty-two patients underwent laparoscopic transhiatal esophagectomy; 19 had esophageal cancer. Two patients were operated on for Barrett esophagus, and 1 patient had achalasia. The majority of patients were men (82%), and the mean age was 59 years (range 15 to 74 years); 1 patient (4.5%) was converted to open surgery. The average operative time was 380 minutes (range 285 to 525 minutes), and the average blood loss was 220 mL; only 3 patients required transfusion. The median hospital stay was 8 days (range 5 to 46 days). Postoperative mortality occurred in 1 patient (4.5%), and postoperative complications developed in 6 patients (27.2%). In the 19 cancer patients, the average number of harvested nodes was 14.3 (range 10 to 19). The average follow-up was 30 months (range 12 to 48 months). The overall survival for cancer patients was 61% (11 of 19), and disease-free survival was 39% (7/19). CONCLUSIONS: Esophagectomy is a major surgery with considerable morbidity and potential mortality. Minimally invasive esophagectomy is a feasible approach that can be safely performed by surgeons with extensive experience in that field. Advantages include less intraoperative blood loss, a smaller incision, and a potentially faster postoperative recovery. In cancer patients, immediate oncologic goals of adequate margins and lymph node dissection can be achieved, and long-term outcome appears to be similar to that found with open approaches.     

Laparoscopic transhiatal esophagectomy: outcomes

Background Laparoscopic transhiatal esophagectomy, indicated for benign and malignant esophageal diseases, is a complex operation, often associated with a high rate of morbidity and mortality. During the past decade this technique has became well accepted among specialized surgeons for the treatment of esophageal cancer, avoiding thoracotomy and reducing open access complications. The aim of the present study was to retrospectively analyze patients with esophageal cancer who underwent laparoscopic transhiatal esophagectomy. Methods From November 1993 to August 2006, 78 patients underwent laparoscopic transhiatal esophagectomy. There were 68 cases of esophageal cancer (57 males and 21 females, age range = 28–73 years) with a predominant rate of squamous cell carcinoma (60.2%). Results The conversion rate was 6.4%. The mean operative time was 153 min with a 12.8% rate of cervical leak and a postoperative (30-day) mortality rate of 5.1%. The four-year survival rate was 19% as determined within a subgroup of 21 patients whose followup during the period was possible. Conclusions Laparoscopic transhiatal esophagectomy is a safe alternative for experienced professionals. This access can improve mortality, hospital stay, and other outcomes when compared with open methods.     

Minimally invasive transhiatal and transthoracic esophagectomy

Background Standard esophagectomy requires either a laparotomy with transhiatal removal of the esophagus or a combination of laparotomy and thoracotomy. Currently, it still is associated with a high rate of morbidity and mortality. Complications leading to greater morbidity and mortality are rarely seen after minimally invasive surgery. The authors present their experience with 25 minimally invasive esophageal resections. Methods Between August 1st, 2003 and November 30th, 2005, the authors performed 25 minimally invasive esophageal resections for 4 woman and 21 men. Data were acquired prospectively. Results In this series, a laparoscopic transhiatal approach was performed in 9 cases, a combined laparoscopic-thoracoscopic procedure in 12 cases, and laparoscopic creation of a gastric tube combined with thoracotomy in 4 cases. No conversion became necessary. The mean operation time was 165 min (range, 150–180 min) for the laparoscopic transhiatal approach and 300 min (range, 240–360 min) for both combination approaches. Using the combined laparoscopic-thoracoscopic procedure, 23 lymph nodes (range, 19–26 lymph nodes) were removed, and using the laparoscopic transhiatal approach, 14 lymph nodes (range, 12–17 lymph nodes) were removed. The median stay in the intensive care unit was 1.5 days (range, 1–22 days), and the overall postoperative stay was 10 days (range, 7–153 days). Two intraoperative complications and two cervical anastomotic leakages were observed. The 30-day mortality rate was 0%. Conclusion The findings demonstrate that laparoscopic transhiatal and combined laparoscopic/thoracoscopic esophagectomy are feasible and can be performed with low rates of morbidity and mortality. Due to an equal extent of lymph node dissection, there should be no difference in long-term survival between minimally invasive surgery and open surgery.     

Anesthesiological hazards during laparoscopic transhiatal esophageal resection: a case control study of the laparoscopic-assisted vs the conventional approach

Background Interest for minimal invasive approach of esophagus resection is increasing. Today, a minimally invasive transhiatal esophagectomy is possible and is accepted widespread. Since cardiopulmonary changes during laparoscopic dissection of the mediastinum has not been studied yet we assessed the anesthesiological consequences of pneumothorax during laparoscopic mediastinal dissection.Methods In this case control study, 25 laparoscopically assisted transhiatal espohagus resections were compared with a control group consisting of 20 open transhiatal esophagus resections. Patient characteristics and intraoperative haemodynamic, respiratory, and ventilatory parameters were assessed.Results The laparoscopic assisted procedure was performed successfully in 12 of the 20 patients. The duration of the laparoscopic assisted procedure, compared to the open group was significantly longer (p<0.05). Intraoperative blood loss was significantly less in the laparoscopic group (p<0.05). Mediastinal dissection resulted in entry of the pleura in 84% of the open and 93% of the laparoscopic assisted procedure. Carbondioxide pneumothorax resulted in increased end-tidal CO₂ and airway pressure levels and decreased lunng compliance. Airway pressure showed a significant difference between the groups (p<0.05). Hemodynamic parameters did not differ between groups significantly. There were no differences in postoperative cardiopulmonary complications.Conclusions Laparoscopic assisted transhiatal esophagectomy is a safe procedure and has no increased risk of postoperative cardiopulmonary complications compared to thr conventional approach. The anesthesiologist and the surgeon must be aware of the potential risk of pleural injury to manage cardiopulmonary compromises and minimize complications.     

Cardiac tamponade: an unusual, lifethreatening complication after transhiatal resection of the esophagus

Transhiatal resection for carcinoma of the distal esophagus is associated with relative high morbidity and mortality. We present a rare case of cardiac tamponade after transhiatal esophagectomy for which emergency sternotomy was performed. Probably the retraction of the heart during exploration of the mediastinum caused a laceration of an epicardial vein. Although very rare, cardiac tamponade should be considered when hemodynamic instability during or after transhiatal esophagectomy occurs.     

Simplifying minimally invasive transhiatal esophagectomy with the inversion approach: Lessons learned from the first 20 cases

HYPOTHESIS: The laparoscopic transhiatal esophagectomy can be simplified and performed safely and effectively by using a novel esophageal inversion technique. DESIGN: Case series describing technique, initial experience, and learning curve with laparoscopic inversion esophagectomy. SETTING: Tertiary care university hospital and veteran's hospital. PATIENTS: Twenty consecutive patients with high-grade dysplasia (n = 16) and esophageal adenocarcinoma (n = 4). INTERVENTION: Laparoscopic inversion esophagectomy, a totally laparoscopic approach to transhiatal esophagectomy that incorporates distal to proximal inversion to improve mediastinal exposure and ease of dissection. MAIN OUTCOME MEASURES: Perioperative end points and complications, compared between the first and second groups of 10 patients. RESULTS: There were 19 men and 1 woman. Median operative time was 448 minutes. Median blood loss was 175 cm3. Median intensive care unit stay was 4 days, and median total hospital stay was 9 days. Overall anastomotic leak rate was 20%. Five patients developed an anastomotic stricture, all successfully managed with endoscopic dilation. There were 2 recurrent laryngeal nerve injuries, which resolved. There was no intraoperative or 30-day mortality. Between the first 10 consecutive cases and last 10 procedures, the incidence of anastomotic leak and stricture formation decreased from 30% to 10% and 40% to 10%, respectively. During this period, the number of lymph nodes harvested increased 9-fold, and duration of intensive care unit stay decreased from 8.00 to 2.50 days. CONCLUSIONS: Laparoscopic inversion esophagectomy is a safe procedure. The learning curve for the inversion approach is approximately 10 operations in the hands of esophageal surgeons with advanced laparoscopic expertise.     

Superficial adenocarcinoma of the esophagus.

OBJECTIVE: Experience with treatment and outcome of superficial adenocarcinoma of the esophagus is limited. The purpose of this study was to evaluate the results of surgical management and identify predictors of survival. METHODS: Between September 1985 and December 1999, 122 patients underwent resection. Eighty-nine percent were men (mean age 63 +/- 10 years; range 35-83 years). Sixty (49%) patients were in endoscopic surveillance programs and 48 (39%) had the preoperative diagnosis of high-grade dysplasia. Forced expiratory volume in 1 second was less than 2 L in 12 (12%). Seventy-five (61%) patients underwent transhiatal esophagectomy. Pathologic stage was N1 in 8 (7%). Pulmonary complications necessitating reintubation (respiratory failure) occurred in 10 (8%) patients. Time-related survival models were developed for decision-making (preoperative), prognosis (operative), and hospital care (postoperative). RESULTS: Operative mortality was 2.5%. Survival at 1, 5, and 10 years was 89%, 77%, and 68%. Preoperative decision-making factors associated with ideal outcome were 1-second forced expiratory volume of more than 2 L, surveillance, preoperative diagnosis of high-grade dysplasia, and planned transhiatal esophagectomy. Prognosis was decreased in younger patients and in those with N1 disease. Postoperative respiratory failure increased mortality. CONCLUSIONS: Surgery is the treatment of choice for superficial adenocarcinoma of the esophagus. The ideal patient has a preoperative diagnosis of high-grade dysplasia found at surveillance, good pulmonary function, and undergoes a transhiatal esophagectomy. Discovery of N1 disease or development of postoperative respiratory failure reduces the benefits of surgery.     

Adenocarcinoma of the distal esophagus and gastric cardia. Comparison of results of transhiatal esophagectomy and thoracoabdominal esophagogastrectomy

Between 1965 and 1984, 72 patients underwent operation for adenocarcinoma of the distal esophagus or gastric cardia. A standard transthoracic esophagogastrectomy and esophagogastrostomy was performed in 43 and a transhiatal esophagectomy without thoracotomy and partial proximal gastrectomy was performed in 29. There was no significant difference between the two groups in age, sex, or TNM tumor staging. The perioperative complication rate was 86% in the esophagogastrectomy patients and 48% in the transhiatal esophagectomy patients (p less than 0.05). Mortality was higher in the esophagogastrectomy group (14%) than in the transhiatal esophagectomy group (7%). Average operative blood loss was greater in the esophagogastrectomy patients (2,510 versus 1,187 ml). Average postoperative hospitalization was longer for the esophagogastrectomy patients (22.2 days versus 12.3 days). Both differences are statistically significant (p less than 0.05). Late results, as evaluated by life-table analysis, showed no significant difference in survival between the two groups of patients. Because the morbidity and mortality rates of transhiatal esophagectomy are as low as or lower than those for esophagogastrectomy, late survival is as good, and palliation is superior (less suture-line tumor recurrence and reflux esophagitis), we believe that transhiatal esophagectomy is the preferred operative approach in patients with adenocarcinoma of the distal esophagus or gastric cardia.     

Indicators of prognosis after transhiatal esophageal resection without thoracotomy for cancer

BACKGROUND: Various techniques have been described for the surgical treatment of esophageal cancer. The transhiatal approach has been debated for its safety and oncologic results. STUDY DESIGN: Between January 1993 and September 1996, 115 patients underwent a transhiatal esophagectomy with curative intent for adenocarcinoma or squamous cell carcinoma of the middle or distal esophagus or esophagogastric junction. Procedure-related hazards, pathologic results, and prognostic factors for survival were evaluated. Median duration of postoperative followup was 27 months (range 1 to 74 months) for all patients and 45 months (range 30 to 74 months) for those alive at final followup. RESULTS: No emergency thoracotomies were experienced. In-hospital mortality was 3.5%. Vocal cord dysfunction (24%) and pulmonary complications (23%) were the most frequent early postoperative complications. A microscopically radical resection was achieved in 73% of patients. Overall survival was 45% at 3 years. In univariate analysis, the most pronounced indicators of longterm survival (p < 0.0001) were radicality of the resection, lymph node involvement, lymph node ratio (ie, the ratio of invaded to removed lymph nodes), and pathologic tumor stage. Multivariate analysis identified the lymph node ratio (p < 0.0001) as the strongest independent predictor of long-term survival, followed by radicality of the resection (p = 0.0064) and duration of ICU stay (p = 0.027). CONCLUSION: Transhiatal esophagectomy without thoracotomy can be considered a safe procedure for resectable cancer of the midesophagus, distal esophagus, or esophagogastric junction. Radicality and survival results were in line with the data reported for traditional transthoracic approaches. A prognostic value of the lymph node ratio was observed. It emphasizes the need for controlled trials aimed at delineating the prognostic impact of an extended lymph node dissection.     

Minimally invasive transhiatal esophagectomy: lessons learned

Background Minimally invasive esophagectomy has the potential to minimize the morbidity of esophageal resection and is particularly suited to the transhiatal approach. This report details our experience with this technique and the lessons we have learned. Methods A retrospective analysis of patients who underwent minimally invasive transhiatal esophagectomy was performed. Parameters assessed included patient demographics, tumor pathology, operative and postoperative course, and survival. Results Eighteen patients underwent minimally invasive transhiatal esophagectomy [median age = 69 years (range = 36–79)]. Seventeen were operated on for cancer, including 13 adenocarcinomas and 4 squamous cell carcinomas (median histological stage = 2, range = 1–3), and 1 for high-grade dysplasia in Barrett’s. One patient had neoadjuvant chemotherapy. Two patients underwent nonemergency conversion to open surgery. The median duration of operation was 300 min (range = 180–450). All anastomoses were end-to-side hand-sewn. No patients received a red cell transfusion. The 30-day mortality was zero. Complications developed in 15 patients, including 7 respiratory and 10 recurrent laryngeal nerve injuries. There were two anastomotic leaks. Six patients developed stenosis requiring dilatation. The median length of stay was 15 days (range = 10–39). The median number of nodes harvested was 10 (range = 2–26). At a median follow-up of 13 months (range = 4–42), 13 patients were alive. Conclusions Minimally invasive transhiatal esophagectomy is feasible in our unit, with acceptable mortality. The high rate of anastomotic stenosis has resulted in a change to a semimechanical, side-to-side isoperistaltic technique. The high rate of recurrent laryngeal nerve injuries has resulted in the avoidance of metal retractors at the tracheo-esophageal groove.     

Extended transthoracic resection compared with limited transhiatal resection for adenocarcinoma of the mid/distal esophagus: five-year survival of a randomized clinical trial

OBJECTIVE: To determine whether extended transthoracic esophagectomy for adenocarcinoma of the mid/distal esophagus improves long-term survival. BACKGROUND: A randomized trial was performed to compare surgical techniques. Complete 5-year survival data are now available. METHODS: A total of 220 patients with adenocarcinoma of the distal esophagus (type I) or gastric cardia involving the distal esophagus (type II) were randomly assigned to limited transhiatal esophagectomy or to extended transthoracic esophagectomy with en bloc lymphadenectomy. Patients with peroperatively irresectable/incurable cancer were excluded from this analysis (n = 15). A total of 95 patients underwent transhiatal esophagectomy and 110 patients underwent transthoracic esophagectomy. RESULTS: After transhiatal and transthoracic resection, 5-year survival was 34% and 36%, respectively (P = 0.71, per protocol analysis). In a subgroup analysis, based on the location of the primary tumor according to the resection specimen, no overall survival benefit for either surgical approach was seen in 115 patients with a type II tumor (P = 0.81). In 90 patients with a type I tumor, a survival benefit of 14% was seen with the transthoracic approach (51% vs. 37%, P = 0.33). There was evidence that the treatment effect differed depending on the number of positive lymph nodes in the resection specimen (test for interaction P = 0.06). In patients (n = 55) without positive nodes locoregional disease-free survival after transhiatal esophagectomy was comparable to that after transthoracic esophagectomy (86% and 89%, respectively). The same was true for patients (n = 46) with more than 8 positive nodes (0% in both groups). Patients (n = 104) with 1 to 8 positive lymph nodes in the resection specimen showed a 5-year locoregional disease-free survival advantage if operated via the transthoracic route (23% vs. 64%, P = 0.02). CONCLUSION: There is no significant overall survival benefit for either approach. However, compared with limited transhiatal resection extended transthoracic esophagectomy for type I esophageal adenocarcinoma shows an ongoing trend towards better 5-year survival. Moreover, patients with a limited number of positive lymph nodes in the resection specimen seem to benefit from an extended transthoracic esophagectomy.     

Immediate preoperative laparoscopic staging for squamous cell carcinoma of the esophagus

BACKGROUND: Conventional preoperative staging for esophageal carcinoma could be inaccurate. Laparoscopy has been applied for the staging of various upper gastrointestinal malignancies. It can identify peritoneal and liver deposits not shown by imaging, and could reduce the number of nontherapeutic laparotomies. This study aimed to evaluate the efficacy of laparoscopic staging for the management of squamous cell carcinoma involving the mid and distal esophagus. METHODS: A retrospective review was performed for all patients with esophageal cancer evaluated for surgical resection from January 1998 to January 2004. Laparoscopy was performed for all the patients with mid and distal esophageal cancer immediately before open gastric mobilization. The efficacy of laparoscopy for the management of squamous cell carcinoma of the esophagus was evaluated. RESULTS: Among the 63 patients with potentially resectable disease shown on conventional imaging, 54 (84%) underwent esophagectomy with curative intent after laparoscopic staging. Seven patients (11%) underwent laparoscopy alone because of abdominal metastases (n = 5) or other medical conditions (n = 2) that precluded esophagectomy. Two patients (3%) had exploratory right thoracotomy without esophagectomy despite normal laparoscopic findings. The sensitivity and specificity of laparoscopic staging were 100% in this series of patients (100% sensitivity and specificity means no false-positives or -negatives). CONCLUSION: Laparoscopic staging is valuable for the management of patients with mid and distal squamous cell carcinoma of the esophagus. Patients with metastatic disease and those with prohibitive surgical risk can thus avoid unnecessary laparotomy and be offered other treatment methods.

Laparoscopically assisted transhiatal resection for malignancies of the distal esophagus

Background Resection of the esophagus remains the only curative therapy for esophageal cancer. Conventional resections are right-side thoracotomy in combination with laparotomy, gastric tube creation, and the transhiatal approach according to Orringer. This study evaluated laparoscopically assisted transhiatal esophagus resection, which offers perfect visualization of the esophagus during mediastinal dissection without the necessity of a thoracotomy.Methods In this study, 25 laparoscopically assisted transhiatal esophagus resections were compared with a historical control group consisting of 20 open transhiatal esophagus resections.Results Nine laparoscopically assisted resections (36%) were converted to open procedures. The operating time was longer in the laparoscopically assisted group (300 vs 257 min; p < 0.05), but laparoscopically assisted esophagus resection was associated with less blood loss (600 vs 900 ml; p < 0.05) and shorter intensive care unit stay (1 vs 2 days; p < 0.05). There were no differences in morbidity, mortality, and hosptital stay. During a shorter follow-up time for the laparoscopic group (17 vs 54 months), 11 patients (44%) in the laparoscopically assisted group and 10 (50%) patients in the open group had recurrence of the disease.Conclusions Laparoscopically assisted transhiatal esophagus resection is a safe procedure with important advantages, as compared with the open procedure, such as less blood loss and shorter intensive care unit stay. At this point, the oncologic consequences are not clear.     

A decade of experience with transthoracic and transhiatal esophagectomy

BACKGROUND: Morbidity and mortality remain significant for transthoracic (TT) and transhiatal (TH) esophagectomy. We report a case-specific approach employing either resection to minimize perioperative morbidity and mortality. METHODS: All primary esophageal resections performed for benign and malignant esophageal disease were reviewed over a 10-year period. The operative approach was tailored to the location and extent of disease and the physiologic reserve of the patient. RESULTS: In all, 115 patients underwent esophagectomy for benign (25) and malignant (90) disease. Fifty-six TT and 59 TH resections were performed. Four emergent TT cases did not have reconstruction. There was 1 hospital mortality. Perioperative transfusion was avoided in 65 patients. Respiratory complications occurred in 15. Three patients had a cervical anastomotic leak requiring open wound drainage. No association between resection type and complication was evident. CONCLUSIONS: The judicious use of both TT and TH esophagectomy resulted in an operative mortality of less than 1%, reduced operative blood loss, and a relatively low rate of perioperative complications.     

Transhiatal esophagectomy

Between 1991-2001, 40 patients underwent esophagectomy without thoracotomy for: caustic esophageal stenosis (26 cases), cervical esophageal cancer (1), lower esophageal cancer (7), and acute post-caustic oesophagitis (2). Thirty-four patients underwent transhiatal esophagectomy, 3 patients had an esophagectomy by "stripping" and in 3 other patients a combination of stripping and transhiatal esophagectomy. Postoperative complications included: injuries of the laryngeal recurrent nerve (2), pulmonary complications (13), anastomotic leakage (5). Two patients died in the postoperative period one from a myocardial infarction and the other from an acute myocardial dilatation. Trans-hiatal esophagectomy can be considered as a viable alternative to transthoracic esophagectomy in the management of the benign and malignant diseases of the esophagus. Transhiatal esophagectomy is a safe method of resection because of its reported lower morbidity and mortality and similar survival rates compared to transthoracic esophagectomy.     

Transhiatal esophagectomy for treatment of benign and malignant esophageal diseases

In 1978 the technique of transhiatal esophagectomy without thoracotomy was rediscovered and now it is widely used in certain, selected, cases. Between 1987 and 2003 we have performed transhiatal esophagectomy in 35 patients with intrathoracic esophageal disease: 13 (37.14%) for benign lesions of the esophagus and 22 (62.85%) for malignant lesions (22.72% upper, 9% middle and 68.18% lower third of the thoracic esophagus). The reconstruction was performed at the same operation in all but two patients. The esophageal substitute was stomach in all but one patient when left colon was used. Hospital mortality was 14.28% with one death due to uncontrollable intraoperative hemorrhage. Major complications included anastomotic leak, recurrent laryngeal nerve paralysis, atelectasis/pneumonia. The advantages of this approach over standard transthoracic esophagectomy are avoidance of a combined thoracoabdominal operation in a debilitated patient and fewer postoperative pulmonary complications and also avoidance of an intrathoracic esophagogastric anastomotic leak with high mortality due to mediastinitis.     

Minimally invasive esophagectomy: thoracoscopic mobilization of the esophagus and mediastinal lymphadenectomy in prone position--experience of 130 patients

BACKGROUND: To evaluate outcomes after minimally invasive or thoracolaparoscopic esophagectomy (TLE) with thoracoscopic mobilization of the esophagus and mediastinal esophagectomy in prone position. Esophagectomies are being performed increasingly by a minimally invasive route with decreased morbidity and shorter hospital stay compared with conventional esophagectomy. Most series report thoracoscopic mobilization of the esophagus and mediastinal lymphadenectomy in the left lateral position with respiratory complications up to 8% and prolonged operative time, probably because of inadequate stance of the surgeon during the thoracoscopic part. This study shows the potential of the thoracoscopic part of the procedure in prone position to ease these difficulties. STUDY DESIGN: From January 1997 through April 2005, TLE was performed in 130 patients. All patients had histologically proved squamous cell carcinoma of the middle third of the esophagus. Only one (0.77%) patient received neoadjuvant chemotherapy. The thoracoscopic part of the procedure was performed in prone position with excellent ergonomics, translating into less operative time and better respiratory results. We performed a minilaparotomy to retrieve the specimen owing to bulky tumors. Feeding jejunostomy and pyloromyotomy were performed in all patients. RESULTS: There were 102 men and 28 women. Median age was 67.5 years (range 38 to 78 years). There was no conversion to open method. Median ICU stay was 1 day (range 1 to 32 days) and median hospital stay was 8 days (range 4 to 68 days). Perioperative mortality was 1.54% (n = 2). Anastomotic leak rate was 2.31% (n = 3). There was no incidence of tracheal or lung injury and a very low incidence of postoperative pneumonia. At mean followup of 20 months (range 2 to 70 months), stage-specific survival was similar to open and other minimally invasive series. CONCLUSIONS: TLE with thoracoscopic part in prone position is technically feasible, with a low incidence of respiratory complications and less operative time required. It provides comparable outcomes with other techniques of minimally invasive esophagectomy and most open series. In our experience, we observed a low mortality rate (1.54%), hospital stay of 8 days, and low incidence of postoperative pneumonia. It has the potential to replace conventional and other techniques of minimally invasive esophagectomy.     

Surgical treatment for poor-risk patients with carcinoma of the esophagus

During the period between 1979 and 1988, 145 patients with cancer of the esophagus were admitted to our department. They were examined for the preoperative risk factors associated with multiple organ function and classified into three groups according to the risk score. Special attention was paid to postoperative pulmonary complications, mortality and the long term results of surgery in the poor-risk patients and the findings analyzed in reference to the operative procedures. The resection rate for the poor-risk group was 41 per cent, however, esophagectomy was only able to be combined with a right thoracotomy and abdominal approach in 26 per cent of the patients in this group. Postoperative pulmonary complications developed in 64 per cent of the poor-risk patients who underwent a transthoracic esophagectomy and in only 25 per cent of those who received a transhiatal esophagectomy, although there was no significant difference in the overall survival rate beteeen these two subgroups. The present observations therefore raised the possibility that transhiatal esophagectomy may improve the results of surgical treatment for poor-risk patients with esophageal cancer.
