ABSTRACT

INTRODUCTION: The authors report long-term outcomes in patients who received neoadjuvant chemoradiotherapy and consequently underwent hybrid oesophagectomy for oesophageal cancer (OC). AIM: To evaluate long-term outcomes in patients suffering from OC, who underwent hybrid oesophagectomy. MATERIAL AND METHODS: Our cohort consisted of patients suffering from OC, who received neoadjuvant chemoradiotherapy. Hybrid esophagectomy was performed 8-10 weeks after oncological treatment. RESULTS: Ninety-four patients underwent surgery for OC from 2011 to 2015. Histology revealed adenocarcinoma in 60.6%, squamous cell carcinoma (SCC) in 36.2%, and other type of cancer in 3.2%. Seventy-three (77.7%) patients with advanced stage (T3-4, N0-2, M0) were indicated to receive neoadjuvant chemoradiotherapy (nCRT). Trans-hiatal hybrid oesophagectomy was performed in 83 (88.3%) patients. Transthoracic hybrid oesophagectomy was performed in 11 (11.7%) patients. Histology of the resected specimens of 18 (24.7%) patients did not reveal OC, i.e. pathological complete response (pCR). In our cohort, we proved an association between occurrence of pCR and age as well as disease-free survival (DFS). The patients who presented with pCR were significantly younger - below 60 years of age (p = 0.017). They also showed significantly higher mean DFS (p = 0.004). CONCLUSIONS: Combined oesophagectomy with neoadjuvant chemoradiotherapy results in a better long-term outcome in patients suffering from oesophageal cancer. In our set of patients who underwent hybrid esophagectomy, satisfactory short-term and especially long-term results of surgical treatment for oesophageal cancer were observed.

ABSTRACT

INTRODUCTION: Malignant granular cell tumor (MGCT) of the esophagus is an extremely rare malignancy with a poor prognosis. Literature describing this condition is not sufficient, especially regarding long-term survival. PRESENTATION OF CASE: A 52-year-old woman presented with dyspnea and slow onset dysphagia. The endoscopy, endoscopic ultrasound (EUS), bronchoscopy, and positron emission tomography (PET)/computed tomography (CT) supported the suspicion of esophageal gastrointestinal stromal tumor (GIST). Open wedge esophagectomy and tracheal resection were performed. The histology proved periodic acid-Schiff (PAS)-positive granules in epithelial cells, hyperchromatic nuclei and the positivity of Protein soluble in 100% ammonium sulfate (S-100), vimentin, neuron-specific enolase, laminin, and myelinic proteins. Local recurrence after 10 months required a two-phase esophagectomy with retrosternal gastroplasty. Bone, liver, and mediastinal metastases occurred 6 months later, with overall survival of 34 months. DISCUSSION: Preoperative histological confirmation is often not reliable. Tracheal invasion increases the perioperative risk and the probability of an unsuccessful resection. Esophagectomy or radical R0 local resection is the only known curative therapy. Repeated resections may increase survival in case of locoregional recurrence. Radiotherapy has a potential for palliative care. CONCLUSION: Esophageal MGCT requires a detailed presentation including long-term survival. Early surgical removal of intramural esophageal neoplasms with potentially malignant features is highly recommended. Radical and/or repeated esophageal resections are the only known therapies with curative potential.

ABSTRACT

AIM: The aim of this study was to reduce the severe respiratory complications of esophageal cancer surgery often leading to death. METHODS: Two groups of patients operated on for esophageal cancer were evaluated in this retrospective analysis. The first group was operated between 2006-2011, prior to the implementation of preoperative microbiological examination while the second group had surgery between 2012-2017 after implementation of this examination. RESULTS: In total, 260 patients, 220 males and 40 females underwent esophagectomy. Between 2006-2011, 113 (87.6%) males and 16 (12.4%) females and between 2012-2017, esophagectomy was performed in 107 (81.7%) males and 24 (18.3%) females. In the first cohort, 10 patients died due to respiratory complications. The 30-day mortality was 6.9% and 90-day was 9.3%. In the second cohort, 4 patients died from respiratory complications. The 30-day mortality was 1.5% and 90-day mortality was 3.1%. With regard to the incidence of respiratory complications (P=0.014), these occurred more frequently in patients with sputum collection, however, severe respiratory complications were more often observed in patients without sputum collection. Significantly fewer patients died (P=0.036) in the group with sputum collection. The incidence of respiratory complications was very significantly higher in the patients who died (P<0.0001). CONCLUSION: The incidence of severe respiratory complications (causing death) may be reduced by identifying clinically silent respiratory tract infections.

ABSTRACT

INTRODUCTION: Respiratory complications (RC) including respiratory failure and adult respiratory distress syndrome (ARDS) affect the outcomes of esophagectomy substantially. In order to decrease their incidence, identification of important features of RC is necessary. AIM: To evaluate the incidence and risk factors of postoperative RC following hybrid esophagectomy. MATERIAL AND METHODS: The retrospective analysis of consecutive hybrid esophagectomies for malignancies (transhiatal laparoscopic or thoracoscopic resection and limited open reconstruction phase) assessed the incidence and outcomes of RC in relation to the patients' age, ASA score, neoadjuvant therapy, type of surgical procedure, TNM stage, the incidence of anastomotic leak and Clavien-Dindo classification. RESULTS: Transhiatal laparoscopic (176, 81.9%) or thoracoscopic hybrid esophagectomy (39, 18.1%, conversion in 7 patients) was completed in 215 patients, 187 (87%) men and 28 (13%) women. Respiratory complications developed in 86 (40%) and severe respiratory failure or ARDS occurred in 29 (13.5%) patients. The overall in-hospital mortality was 7.4%, 30-day mortality 5.6% (RC 9, myocardial infarction 1, conduit necrosis 1), and 90-day mortality a further 1.8% (multiple organ failure, ARDS). The incidence of RC correlates significantly with ASA score II and III (p = 0.0002) and Clavien-Dindo grade 4 and 5 in severe RC (p < 0.0001). Furthermore, hospital stay (p < 0.0001) and mortality (p < 0.0001) were significantly increased in RC. CONCLUSIONS: The results show a higher occurrence of RC in polymorbid patients and patients with severe complications according to the Clavien-Dindo classification. Adequate risk management including surgical technique and perioperative prophylaxis and therapy of RC should be studied and standardized.

ABSTRACT

Esophageal and gastric cancers represent tumors with poor prognosis. Unfortunately, radiotherapy, chemotherapy, and targeted therapy have made only limited progress in recent years in improving the generally disappointing outcome. Immunotherapy with checkpoint inhibitors is a novel treatment approach that quickly entered clinical practice in malignant melanoma and renal cell cancer, but the role in esophageal and gastric cancer is still poorly defined. The principal prognostic/predictive biomarkers for immunotherapy efficacy currently considered are PD-L1 expression along with defects in mismatch repair genes resulting in microsatellite instability (MSI-H) phenotype. The new molecular classification of gastric cancer also takes these factors into consideration. Available reports regarding PD-1, PD-L1, PD-L2 expression and MSI status in gastric and esophageal cancer are reviewed to summarize the clinical prognostic and predictive role together with potential clinical implications. The most important recently published clinical trials evaluating checkpoint inhibitor efficacy in these tumors are also summarized.

ABSTRACT

INTRODUCTION: Intraoperative esophagogastroduodenoscopy (IOG) is a diagnostic and therapeutic method for a variety of special conditions in upper gastrointestinal (UGI) pathology. The indication remains individual due to insufficient evidence and limited training of surgeons in digestive endoscopy. AIM: To evaluate the indications, benefits and risks of IOG. MATERIAL AND METHODS: A single-center retrospective study of 110 consecutive IOGs in 104 patients was performed. The preoperative plan, the timing of IOG, preoperative evaluation, intraoperative finding, localization of the pathology, type of the procedure, change of expected therapy and complications were assessed. RESULTS: The cohort comprised 29 esophageal tumors, 5 tumors of the cardia, 36 gastric tumors, gastrointestinal bleeding (8), esophageal diverticula (3), perforations (3), GERD (5), mediastinal pathology (3), fistula (4), assessment of nutrition (10), duodenal adenoma (2), ulcer disease, esophageal stenosis and gastric volvulus. The indication for IOG was established preoperatively in 79% and intraoperatively in 21%. The lesion was localized in 96.4%. The therapy was altered to a wider resection (11), smaller resection (5), localization and surgical therapy of bleeding (8) or allowed minimally invasive surgery (25). A total of 3 postoperative complications included gastric perforation and positivity of resection line (following EMR/ESD) and recurrent bleeding. The 30-day mortality reached 3.6% without a specific cause in IOG. CONCLUSIONS: The IOG is a complementary method in the diagnosis and treatment of UGI pathology. It enables minimally invasive finalization of the procedures and individualization of the therapy.

ABSTRACT

The prognosis of esophageal cancer (EC) is poor, despite considerable effort of both experimental scientists and clinicians. The tri-modality treatment consisting of neoadjuvant chemoradiation followed by surgery has remained the gold standard over decades, unfortunately, without significant progress in recent years. Suitable prognostic factors indicating which patients will benefit from this tri-modality treatment are missing. Some patients rapidly progress on the neoadjuvant chemoradiotherapy, which is thus useless and sometimes even harmful. At the same time, other patients achieve complete remission on neoadjuvant chemoradiotherapy and subsequent surgery may increase their risk of morbidity and mortality. The prognosis of patients ranges from excellent to extremely poor. Considering these differences, the role of drug metabolizing enzymes and transporters, among other factors, in the EC response to chemotherapy may be more important compared, for example, with pancreatic cancer where all patients progress on chemotherapy regardless of the treatment or disease stage. This review surveys published literature describing the potential role of ATP-binding cassette transporters, the genetic polymorphisms, epigenetic regulations, and phenotypic changes in the prognosis and therapy of EC. The review provides knowledge base for further research of potential predictive biomarkers that will allow the stratification of patients into defined groups for optimal therapeutic outcome.

ABSTRACT

Esophageal cancer (EC) consists of tumors with a generally poor prognosis, and treatment options for patients with disease recurrence are extremely limited. Due to this poor patient prognosis, the possible treatment toxicity should be carefully balanced against its potential benefit and patient quality of life. Stereotactic body radiotherapy (SBRT) is a rapidly expanding novel technique combining a short treatment time together with high local efficacy and an acceptable toxicity profile. There are no publications thus far presenting data regarding the usage of SBRT utilizing a conventional linear accelerator in locally recurrent EC patients. In the present study, 2 patients with recurrent EC in the neck lymph nodes were treated by SBRT in the Department of Oncology, University Hospital Olomouc, Czech Republic. The treatment dose was 30 and 40 Gy in 5 daily fractions, with a prescribed dose to 65 and 81% isodose, for each patient respectively, utilizing a volumetric arc therapy technique, a 6-MV photon beam and an Elekta Synergy linear accelerator. The treatment was delivered without any unintentional treatment interruptions and without any treatment-related acute toxicity. The maximum dose in the patients was 45.9 and 49.2 Gy, respectively. The maximum doses for the surrounding major blood vessels were 35.4 and 45.7 Gy, respectively. Maximum doses to the trachea and the esophagus in the first patient were 32.6 and 27.0 Gy. In the second patient, these doses were not clinically significant. SBRT utilizing linear accelerators should be considered in patients with localized recurrent EC, offering the patients the chance for local control with minimal treatment toxicity.

ABSTRACT

Esophageal cancer is a disease with disappointing prognosis. Currently, there are no predictive factors that can identify patients who on the one hand would likely benefit from tri-modality management and, on the other hand, would not be significantly affected by the morbidity accompanying the treatment. MicroRNAs are short non-coding RNAs responsible for post-transcriptional modification of gene expression by binding to 3'-UTR of messenger RNA and represent emerging potential predictive biomarkers of treatment (chemotherapy and radiotherapy) efficacy and toxicity. We reviewed the current literature, addressing the potential predictive role of microRNAs for efficacy of chemotherapy (specifically cisplatin, 5-fluorouracil, doxorubicin and paclitaxel) and radiotherapy, including predicted targets in the cell. Altogether 82 articles were identified and included in this review. This may be the first review on this topic specifically focusing on neoadjuvant treatment of esophageal cancer.

ABSTRACT

INTRODUCTION: The indication for minimally invasive esophagectomy (MIE) in esophageal cancer has an increasing tendency. AIM: To present our cohort of patients operated on between 2006 and 2012. MATERIAL AND METHODS: A single centre study of 106 consecutive esophagectomies performed for esophageal cancer by a minimally invasive approach in 79 patients was performed. Transhiatal laparoscopic esophagectomy (THLE) was performed in 66 patients, transthoracic esophagectomy (TTE) in 13 patients, with histological findings of squamous cell carcinoma in 28 and adenocarcinoma in 51 patients. RESULTS: The MIE was completed in 76 (96.2%) patients. In cases of TTE, the operation was converted to an open procedure in 3 cases. Operation time ranged from 225 to 370 min (average 256 min). The number of lymph nodes removed was 7-16 (11 on average). The postoperative course was without any complications in 54 (68.3%) patients. Respiratory complications were observed in 14 (17.7%) patients (9 following THLE, 5 following TTE). Other serious complications included acute myocardial infarction (1 patient) and necrosis of the gastroplasty (1 patient). Anastomotic dehiscence was observed in 8 patients, left recurrent laryngeal nerve paralysis in 8 patients, intra-abdominal abscesses in 2 patients, and pleural empyema in 1 case. The overall morbidity of patients operated on by MIE was 31.6%. Thirty-day mortality was 10.1%. CONCLUSIONS: The MIE belongs to the therapeutic portfolio of surgical procedures performed for esophageal cancer. Successful performance requires erudition of the surgical team in both minimally invasive procedures as well as in classical surgical treatment of esophageal cancer; therefore centralization of patients is imperative.

ABSTRACT

INTRODUCTION: Barrett's esophagus is the most significant precancer of the esophagus. Its malignization gives rise to most adenocarcinomas of the esophagus. Therefore selection of adequate therapy for this precancerous condition is of the utmost importance. AIM: The authors of the work addressed the question of whether effective therapy of reflux disease alone may halt the process of malignization of Barrett's mucosa or even cause its regression. MATERIAL AND METHODS: The analyzed set comprised 50 patients with Barrett's esophagus, who in 48 cases underwent laparoscopic fundoplication and in two cases underwent an indirect antireflux procedure in the form of gastric resection with a Roux-en-Y gastrojejunal anastomosis. The effect of the procedure was evaluated by comparing preoperative and postoperative endoscopic examinations, as well as histological analysis by biopsy taken from Barrett's mucosa. RESULTS: In 19 patients (38%), Barrett's mucosa was not detected postoperatively. An improved finding in terms of disappearance of mucosal dysplasia was found in 8 (16%) patients. Findings remained unchanged in 18 (36%) patients. In 5 (10%) patients progression of the disease was discovered. CONCLUSIONS: A surgical antireflux procedure, primarily in the form of laparoscopic fundoplication, is considered an effective method for treating Barrett's esophagus up to the stage of mild dysplasia. If this therapy is unsuccessful, the method of choice is local therapy, either an endoscopic mucosectomy or radiofrequency ablation.

ABSTRACT

Metastases of esophageal carcinoma to the skeletal muscle are rare, but the incidence may be increasing because of better diagnosis resulting from widespread use of positron emission tomography/computed tomography (PET/CT). A cohort of 205 patients with esophageal carcinoma treated at our center who had PET/CT between 2006 and 2010 was retrospectively evaluated for the presence of skeletal muscle metastases. Four patients had skeletal muscle metastases of esophageal carcinoma, including two patients with squamous cell carcinoma. In another patient with squamous cell carcinoma of the esophagus and synchronous skeletal muscle metastases, muscle metastases were subsequently shown to be related to second primary pancreatic adenocarcinoma. In all cases, skeletal muscle metastases were the first manifestation of systemic disease. In three patients palliation was obtained with the combination of external beam radiation therapy, systemic chemotherapy or surgical resection. Skeletal muscle metastases are a rare complication of esophageal carcinoma.

ABSTRACT

AIM: To describe our experience with esophagectomy for esophageal cancer and, the development and treatment of complications arising from the surgery. MATERIAL AND METHODS: From 2007 to 8/2010, esophagectomy for esophageal carcinoma was performed in 75 patients at the 1(st) Surgical Clinic. Primary esophagectomy was indicated in 20 patients with T1N0 stage or in cases where neoadjuvant treatment was contraindicated. 55 patients with T2,3N0,1 stages received neoadjuvant radiochemotherapy. Esophagectomy was performed via an abdominal approach (transhiatal laparoscopy in 44 patients, laparotomy in 3 patients) and a thoracic approach (thoracoscopy in 10 patients, thoracotomy in 18 patients). RESULTS: In 18 cases, one or both pleural cavities were opened by means of dissection of the mediastinal pleura during the transhiatal laparoscopic esophagectomy. The morbidity was 26.6% and the following complications were encountered: pulmonary (15 patients), anastomosis dehiscence (5), postoperative bleeding in the mediastinum (1), fistula between trachea and transposition (1), paresis of the left recurrent nerve (8), infectious complications in the abdominal cavity (2), thoracic cavity (1), and early complications (2). The sixty-day mortality was 8% and this was mostly due to pulmonary complications (4 patients) but included coronary thrombosis (1) and transposition necrosis (1). CONCLUSION: The dominating complications of esophagectomy were pulmonary (20 %). The remaining serious complications cannot be completely eliminated but if diagnosed in time and treated in a correct algorithm they do not have to imminently threaten the lives of patients.

ABSTRACT

BACKGROUND: Esophageal cancer is a serious diagnosis that has a relative incidence of 4/100,000 inhabitants in the Czech Republic. This disorder is managed predominantly by surgery. The steps to improving the outcome of treatment include a multifactorial approach. The role of operative technique in improving outcomes seems to have reached its limits. However, antibiotic prophylaxis and the treatment of complicating bacterial infections continue to play important roles. METHODS: A total of 85 patients with strictly defined antibiotic prophylaxis during surgical esophagectomy were included in our study. Bacterial strains were isolated from the patient's clinical materials after operation; only one strain from each patient, the first to be isolated, was tested for antibiotic sensitivity. RESULTS: Infectious complications were observed in 15.3% of patients and the mortality rate from infectious complications reached 30.8%. The most frequently documented complicated infection was pneumonia (69.2%) and the most frequent pathogens were enteric bacteria (56.5%). Some bacterial strains producing extended-spectrum beta-lactamases and AmpC beta-lactamases were found. CONCLUSIONS: The infections in our patient set were of endogenous origin. In cases of pneumonia, it is appropriate to begin with antibiotics effective against enteric bacteria and Pseudomonas aeruginosa.

ABSTRACT

INTRODUCTION: Gastrointestinal stromal tumors are among the most frequent mesenchymal tumors of the gastrointestinal tract; the incidence of these tumors in the esophagus is less than 5%. Prognosis depends on localization, size, mitotic activity and possible invasion of surrounding structures. Minimally invasive surgery may be maximally utilized for removal of these tumors from the esophageal wall. This operation is usually performed thoracoscopically or laparoscopically and using the "rendez-vous" method - with endoscopic navigation. AIM: To evaluate a set of patients with benign tumor of the esophagus who were operated on at the First Department of Surgery from 2006 to 2011. MATERIAL AND METHODS: In the years 2006-2011 a total of 11 patients with benign tumors of the esophagus underwent operation. RESULTS: Of the 11 patients with esophageal tumor, 5 were diagnosed with gastrointestinal stromal tumor, 5 with leiomyoma and in one patient the lesion was described as heterotopy of the pancreas. We used the minimally invasive rendez-vous method with endoscopic navigation in 9 cases. All patients healed primarily and were released from hospital on the 4(th)-7(th) day. These patients are being followed up as outpatients and recurrence of the tumor has not been observed in any of them. CONCLUSIONS: Minimally invasive treatment of benign tumors of the esophageal wall is considered to the method of choice. Due to possible complications and the need for subsequent therapy in some patients, these procedures should be centralized to departments with experience in esophageal, thoracic and minimally invasive surgery.

ABSTRACT

PURPOSE: This study was designed to evaluate our experience with the treatment of postoperative anastomotic leaks and benign esophageal perforations with covered biodegradable stents. MATERIALS AND METHODS: From 2008 to 2010, we treated five men with either an anastomotic leak or benign esophageal perforation by implanting of covered biodegradable Ella-BD stents. The average age of the patients was 60 (range, 38-74) years. Postoperative anastomotic leaks were treated in four patients (1 after esophagectomy, 1 after resection of diverticulum, 2 after gastrectomy). In one patient, perforation occurred as a complication of the treatment of an esophageal rupture (which occurred during a balloon dilatation of benign stenosis) with a metallic stent. RESULTS: Seven covered biodegradable stents were implanted in five patients. Primary technical success was 100%. Clinical success (leak sealing) was achieved in four of the five patients (80%). Stent migration occurred in three patients. In two of these patients, the leak had been sealed by the time of stent migration, therefore no reintervention was necessary. In one patient an additional stent had to be implanted. CONCLUSION: The use of biodegradable covered stents for the treatment of anastomotic leaks or esophageal perforations is technically feasible and safe. The initial results are promising; however, larger number of patients will be required to evaluate the capability of these biodegradable stents in the future. The use of biodegradable material for coverage of the stent is essential.

ABSTRACT

AIM: The authors evaluate the results of mini-invasive therapy in patients diagnosed with upside-down stomach. MATERIAL AND METHODS: From 1998 to 2008, a total of 27 patients diagnosed with upside-down stomach were surgically treated at the 1st Department of Surgery, University Hospital Olomouc. Before the operation, patients were examined endoscopically and a barium swallow was performed. In all 27 patients (100%), the operation was performed electively laparoscopically. The principle of the operation in all cases was reposition of the stomach into the abdominal cavity, resection of the hernial sac and hiatoplasty. In addition, in 15 patients (56%) with reflux symptoms or endoscopic findings of reflux oesophagitis, fundoplication in Nissen's modification was also performed. Fundopexy was indicated in 12 patients (44%). RESULTS: In all patients (100%), the operation was performed mini-invasively; conversion to an open procedure was never necessary. In 3 cases (11%), the left pleural cavity was opened during the operation; this was treated by introducing a chest drain. The operation mortality in the patient set was zero; morbidity was 11%. A year after the operation, patients were re-examined, and follow-up endoscopy and barium swallow were performed. CONCLUSIONS: In all patients diagnosed with upside-down stomach, surgical treatment is indicated due to the risk of developing severe complications. Mini-invasive surgical therapy in the hands of an experienced surgeon is a safe procedure which offers patients all the benefits of mini-invasive therapy with promising short- and long-term results.

ABSTRACT

BACKGROUND/AIMS: The trimodality therapy including chemotherapy, external beam radiation and surgery is widely accepted as the standard of care in patients with locoregional esophageal carcinoma. METHODOLOGY: We have performed a retrospective analysis of patients with locoregional esophageal carcinoma treated with chemoradiation. RESULTS: One-hundred and fifty-two consecutive patients with non-metastatic adenocarcinoma or squamous cell esophageal carcinoma treated with chemoradiation were included in the present analysis. The median survival of the whole group was 12 months. The estimated 3- and 5-year survival rates were 24% and 19%, respectively. On multivariate analysis, female sex, weight loss and serum albumin were independent negative predictors of survival. Among 140 patients who survived more than 3 months, weight loss, female sex and therapy with paclitaxel were negatively associated with prognosis, and among 109 patients surviving more than 6 months the dose of cisplatin and surgery were independent prognostic factors. Pathologic complete response was not predictive of prognosis. CONCLUSIONS: Long-term survival is obtained in only about 20% of patients with carcinoma of the esophagus treated with chemoradiation. Female sex, weight loss and low serum albumin are independent indicators of poor prognosis. Among treatment-related factors, higher dose of cisplatin and esophagectomy were independent predictors of better prognosis, while administration of paclitaxel was associated with poor prognosis.

ABSTRACT

BACKGROUND/AIMS: Classical operation approaches, used for decades during subtotal esophageal resection for esophageal carcinoma, have certain disadvantages. The transhiatal "blind" approach according to Orringer lacks sufficient radicality, the thoracotomic approach is burdened by serious postoperative complications, primarily respiratory. These disadvantages are eliminated to a great extent by use of the video-assisted laparoscopic transhiatal approach, which is presented in our study. METHODOLOGY: Between 2000-2006 forty-three patients with esophageal cancer underwent video-laparoscopic transhiatal esophagectomy. In all patients passage was renewed by esophagogastroplasty, constructed by placing the neoesophagus in the posterior mediastinum, anastomosis with the cervical esophagus from a laparotomy. Prior to the operation, 27 patients underwent neoadjuvant radio-chemotherapy. Chemotherapy consisted of 5 fluorouracil and cisplatinum, and radiotherapy with a total dose of 50 Gy. RESULTS: The extirpation phase was completed laparoscopically in all patients. Right-sided pneumothorax was seen in 27 patients, in six cases postoperative manifestation of left vocal chord paresis due to damage to the recurrent laryngeal nerve was observed, in 2 patients a fistula developed in the cervical anastomosis, which in all cases healed spontaneously. The operation time ranged between 225-370 minutes, the average time being 256 minutes. The mini-invasive phase took an average of 40 minutes. One patient died 57 days after the operation due to respiratory insufficiency. The average hospital stay was 12.2 days. CONCLUSIONS: The video-assisted laparoscopic transhiatal approach proved to be very useful during subtotal esophageal resection. In tumors localized in the lower portion of the esophagus, it completely replaces the transhiatal "blind" approach according to Orringer and, in comparison, eliminates operative hemorrhagic complications, which are more frequent in "blind" extirpations, especially in patients after neoadjuvant therapy. It also enables performing a lymphadenectomy, which is not possible using the "blind" approach. In tumors of the middle thoracic esophagus, which are inaccessible by the original Orringer's approach, it eliminates the need for a thoracotomy, which significantly contributes to the decrease of respiratory complications.

ABSTRACT

BACKGROUND/AIMS: We evaluated neoadjuvant use in managing patients with esophageal carcinoma and its effects on the surgical resection and outcomes. METHODOLOGY: Patients prior to esophageal resection were offered the opportunity to receive a neoadjuvant cytostatic regimen (CDDP + FU, CDDP, or TAX + FU). Retrospective tumor chemoresistance analysis using the MTT test was also performed. RESULTS: Seventy patients were operated from 2001 until May 2004. A total of 55 resections were performed with preoperative neoadjuvant therapy and 15 elected to only undergo surgery without neoadjuvant therapy. No deaths occurred as a result of surgery or neoadjuvant therapy, but complications included fistulas and hemorrhages. CONCLUSIONS: There was no significant difference between the postoperative complications among the neoadjuvant and non-neoadjuvant groups. This therapy therefore does not have any influence on the course or results of surgical resection. MTT testing did not demonstrate any particular usefulness in tailoring neoadjuvant therapy. Chemoresistance could only be retrospectively evaluated and the results may be affected after cytostatic therapy. The long-term outcomes have not been evaluated yet due to the short follow-up time in our patient group.
