Distant lymph node metastases caused by esophageal cancer invasion to the lamina propria: a case report.

BackgroundPathological examination after endoscopic submucosal dissection revealed that a 62-year-old male had esophageal squamous cell carcinoma with lamina propria mucosal invasion and lymphatic permeation.Case presentationThe patient underwent subtotal esophagectomy and reconstruction as an additional therapy. At 3 years and 4 months after esophagectomy, enlargement of abdominal para-aortic lymph nodes metastases was detected by computed tomography scanning. A total of 50.4 Gy of radiation and two cycles of 5-fluorouracil plus cisplatin were administered. The lymph node metastases were markedly reduced by chemoradiotherapy; however, at 1 year and 1 month later (4 years and 5 months after esophagectomy), left adrenal gland recurrence was found. Although resection was performed, the patient died from cancer progression at 5 years and 4 months after esophagectomy.ConclusionsThis case demonstrates that esophageal squamous cell carcinoma with invasion to the lamina propria and lymphatic permeation has the potential to cause distant metastases.

Type III Achalasia Cardia with Epiphrenic Diverticulum Treated By Subtotal Esophagectomy

Type III Achalasia Cardia with Epiphrenic Diverticulum Treated By Subtotal Esophagectomy

Development of fistula between esophagogastric anastomotic site and cartilage portion of trachea after subtotal esophagectomy for cervical esophageal cancer: a case report.

A 65-year-old man with cT3N2M0 stage III cervical esophageal cancer underwent subtotal esophagectomy and gastric tube reconstruction through the retrosternal route after neoadjuvant chemoradiotherapy. The anastomosis was located adjacent to the left side of the trachea, and a circular stapler was used for anastomosis. Postoperative anastomotic leakage occurred, and an esophagotracheal fistula between the esophagogastric anastomotic site and cartilage portion of the trachea was observed on postoperative day 44. The patient underwent division of the fistula, direct suturing of the anastomotic leakage site, left pectoralis major muscle flap placement, and tracheotomy. He was discharged home on postoperative day 120 on an oral diet. All previous reports of tracheobronchial fistula describe the occurrence of the fistula at the membranous portion of the trachea. The formation of a fistula between the esophagogastric anastomotic site and cartilage portion of the trachea is considered a possible complication when a high esophagogastric anastomosis is created.

The pretreatment Controlling Nutritional Status (CONUT) score is an independent prognostic factor in patients with resectable thoracic esophageal squamous cell carcinoma: results from a retrospective study.

BackgroundThe purpose of this study was to investigate the impact of the Controlling Nutritional Status (CONUT) score on survival compared with the platelet to lymphocyte ratio (PLR), the neutrophil to lymphocyte ratio (NLR), and the Glasgow Prognostic Score (GPS) in patients with resectable thoracic esophageal squamous cell carcinoma (ESCC).MethodsOne hundred eighty-five consecutive patients who underwent subtotal esophagectomy with curative intent for resectable thoracic ESCC were retrospectively reviewed. Time-dependent receiver operating characteristic curve analyses for 3-year overall survival (OS) as the endpoint were performed, and the maximal Youden indices were calculated to assess discrimination ability and to determine the appropriate cut-off values of CONUT, PLR, and NLR. The patients were then classified into high and low groups based on these cut-off values. Correlations between CONUT and other clinicopathological characteristics were analyzed. Prognostic factors predicting overall survival (OS) and relapse-free survival (RFS) were analyzed using Cox proportional hazards models.ResultsThe areas under the curve predicting 3-year OS were 0.603 for CONUT, 0.561 for PLR, 0.564 for NLR, and 0.563 for GPS. The optimal cut-off values were two for the CONUT score, 193 for PLR, and 3.612 for NLR. The high-CONUT group was significantly associated with lower BMI, high-PLR, high-NLR, and GPS1/2 groups. On univariate analysis, high-CONUT, high-PLR, high-NLR, and GPS 1/2 groups were significantly associated with poorer OS and RFS. Of these factors, multivariate analysis revealed that only the CONUT score was an independent prognostic factor for OS (HR 2.303, 95 % CI 1.191–4.455; p = 0.013) and RFS (HR 2.163, 95 % CI 1.139–4.109; p = 0.018).ConclusionsThe CONUT score was an independent predictor of OS and RFS before treatment and was superior to PLR, NLR, and GPS in terms of predictive ability for prognosis in patients with resectable thoracic ESCC.

Endoscopic anti-reflux valve for post-esophagectomy reflux: an animal study.

Background and study aims: Gastric reflux into the remnant esophagus after subtotal or partial esophagectomy is associated with impairment in patient quality of life. We evaluated the feasibility, safety, and potential effectiveness of a novel procedure using a new endoscopic suturing device to create an anti-reflux valve (funnel) in pigs after esophagectomy with gastric tube reconstruction. Methods: The endoscopic procedure was performed in four pigs using a semi-full-thickness endoscopic suturing system (OverStitch; Apollo Endosurgery, Austin, Texas, USA). The operating time, funnel height, ratio of the height of the funnel to the diameter of the gastric tube, and adverse events associated with the procedure were evaluated. The "reflux angle" was measured morphologically and functionally during a reflux induction test, using contrast medium or artificial gastric fluid, by tilting the operating table gradually from a head up to a head down position. Reflux angles before and after funnel creation were compared. Results: The procedure was successful in all four animals. The median operating time was 43 minutes, and the median funnel height was 17 mm (56.7 % of gastric tube diameter). There were no adverse events associated with the procedure. The reflux angle was lower after the procedure compared with before in both morphological and functional assessments in all four cases. Conclusions: Endoscopic anti-reflux funnel creation using OverStitch was feasible, safe, and potentially effective.

Esophagectomy for end‐stage achalasia

End-stage achalasia is rarely effectively addressed with conservative treatments, as food must traverse a serpiginous route to reach the stomach. Botox injections in the setting of end-stage achalasia will likely provide minimal temporary palliation at best, pneumatic dilation has higher risks of perforation, and laparoscopic myotomy, while minimally invasive, has presented poor results. Under these circumstances, there are many proposed procedures to restore a viable alimentary condition to patients, from partial to subtotal resection of the esophagus; each of procedures confers both advantages and specific risks. Subtotal esophagectomy must be indicated for end-stage disease (tortuous or sigmoid esophagus) and persistent dysphagia after failed interventions. When performed by experienced hands, the procedure can be undertaken successfully, with acceptable postoperative morbidity and mortality, improvement of symptoms, and a good long-term quality of life in the majority of patients.

MINIMALLY INVASIVE ESOPHAGECTOMY THROUGH MODIFIED MCKEOWN TRIPLE APPROACH WITH ESOPHAGEAL RECONSTRUCTION AND GASTRIC PULL-UP FOR THORACIC ESOPHAGEAL CARCINOMA

We present the technique of triple approach minimally invasive subtotal esophagectomy: thoracoscopy, laparoscopy and left cervicotomy with gastric pull-up and cervical esogastric anastomosis in a 59 y.o patient. He was diagnosed with a middle thoracic esophageal tumor. The histologic report, thoracic CT and echoendoscopy confirmed the presence of scuamos esophageal carcinoma.

Management and outcomes of anastomotic leaks after oesophagectomy.

Leaks following oesophagectomy include true anastomotic leaks, leaks from the gastrotomy and gastric conduit necrosis. Historically, these complications were associated with high mortality rates. Recent improvements in outcome have been attributed to the wider use of oesophageal stents in patient management. This study examined outcomes of patients who developed a leak in a single high-volume institution that did not use stenting as a primary treatment modality. All patients undergoing an oesophagectomy between January 2009 and December 2013 were included. Patients were identified from a prospectively maintained database. A total of 390 oesophagectomies were performed (median age 65 (range 32-81) years). In 96·7 per cent of patients this was a two-stage subtotal oesophagectomy. Overall in-hospital and 90-day mortality rates were both 2·1 per cent (8 patients). Some 31 patients (7·9 per cent) developed a leak (median age 64·5 (range 52-80) years), of whom 27 (87 per cent) were initially managed without surgery, whereas four (13 per cent) required immediate thoracotomy. The median length of stay for patients with a leak was 41·5 (range 15-159) days; none of these patients died. Leaks can be managed with excellent outcomes without using oesophageal stents. The results do not support the widespread adoption of endoscopic stenting.

Spirometric Lung Age Predicts Postoperative Pneumonia After Esophagectomy.

Despite advances in treatment, postoperative pneumonia remains a major problem after esophagectomy. Lung age has been proposed as a comprehensive indicator for respiratory function. The aim of this study is to reveal the efficacy of lung age in predicting occurrence of pneumonia after esophagectomy. We assessed 342 consecutive patients who underwent subtotal esophagectomy for primary esophageal cancer from 2011 to 2014. Lung age was calculated from the preoperative spirometric test using the methods advocated by the Japanese Respiratory Society. We investigated factors predicting the occurrence of postoperative pneumonia after esophagectomy. The incidence of postoperative pneumonia was 28.9%. According to the Clavien-Dindo classification, grade II and grade III-V pneumonia were observed in 21.3 and 7.6% patients, respectively. In multivariate logistic regression analysis for the factors predicting the occurrence of postoperative pneumonia, higher lung age (p=0.010) and lower body mass index (p=0.006) were independent factors. Patients with grade III-V pneumonia tended to have higher lung age than those with grade II pneumonia (p=0.084). In addition, lung age was significantly higher in patients who experienced pneumonia within postoperative days 7 than those who experienced pneumonia after postoperative days 7 (p=0.028). Spirometric lung age was associated with occurrence, severity, and time of onset of postoperative pneumonia after esophagectomy. This simple parameter deserves a greater consideration as a predictor of postoperative pneumonia after esophagectomy and can support both surgeons and patients in understanding the status of respiratory function.

Mixed spindle and epithelioid cell type gastrointestinal stromal tumor of the esophagus: a case report

Fewer than 1 % of gastrointestinal stromal tumors (GISTs) are of the esophagus. This report describes a 63-year-old female diagnosed with mixed spindle/epithelioid cell GIST of the esophagus. She was admitted to our hospital with symptoms of nausea and hematemesis. Preoperative imaging showed a huge submucosal tumor in the lower thoracic and abdominal esophagus. Pathologic examination of an endoscopic biopsy sample suggested squamous cell carcinoma. She underwent subtotal esophagectomy and reconstruction with a gastric tube. Postoperative pathological diagnosis revealed a mixed spindle/epithelioid cell type GIST. The tumor measured 8 × 6 cm, with 30–50 mitotic counts per high power field, immunohistochemical positivity for C-kit (CD117) and CD34 and high risk by modified Fletcher classification. Adjuvant chemotherapy with imatinib mesylate was started 3 months after surgery. Preoperative pathological examination, including staining for CD117 and CD34, of biopsy samples of apparently stromal tumors may be required to rule out rare subtypes of GIST.

Short-term outcomes after conventional transthoracic esophagectomy.

In our department, we have attempted to reduce the incidence of complications of conventional esophagectomy. The objective of this retrospective study was to report the short-term outcomes of esophagectomy. We reviewed 138 consecutive patients who had undergone subtotal esophagectomy by combined laparotomy via a 12-cm upper abdominal vertical incision combined with right anterior muscle-sparing thoracotomy from August 2010 to August 2014. Most of the cervical para-esophageal lymph node dissection was completed within the thoracic cavity. We performed three-field dissection in patients with tumors in the upper or middle third of the esophagus with clinical lymph node metastases in the superior mediastinum; the others underwent two-field dissection. We performed neck anastomoses in patients undergoing three-field dissection and thoracic anastomoses in those undergoing two-field dissection. Effective postoperative pain management was achieved with a combination of epidural anesthesia and paravertebral block. Postoperative rehabilitation was instituted for early ambulation and recovery. Enteral nutrition via a duodenal feeding tube was administered from postoperative day 2. Median hospital stay after surgery was 15 days (range, 10-129). Rates for both 30-day and in-hospital mortality were 0%. Morbidity rate for all Clavien-Dindo grades was 41.3%, whereas the morbidity rate for Clavien-Dindo grades III and IV was 7.2%. Anastomotic leakage developed in two patients (1.4%), recurrent laryngeal nerve palsy in 11 (8.0%), and pneumonia in nine (6.5%). Good short-term outcomes, especially regarding anastomotic leaks, were achieved by consistent improvements in surgical techniques, optimization of several operative procedures, and appropriate perioperative management.

A case of adenoid cystic carcinoma of the esophagus.

Esophageal adenoid cystic carcinoma (EACC) is a very rare form of malignant tumor in the esophagus. Here, we report the case of a 78-year-old man who was diagnosed with EACC by preoperative endoscopic biopsy. Thoracoscopy-assisted subtotal esophagectomy with lymph node dissection was carried out. Microscopic examination of the resected specimen suggested that the tumor invaded to submucosal layer and showed no lymph node metastasis. Histologically, tumor primarily exhibited an alveolar solid pattern with partial cribriform and tubular patterns. Alcian blue staining showed many mucoid materials within the glandular cavity formed by tumor cells. Immunohistochemical studies revealed that the tumor cells reacted with pan-cytokeratin immunostains and expressed vimentin and S-100 protein. Collectively, the tumor was diagnosed as primary EACC, T1bN0M0 according to “Japanese Classification of Esophageal Cancer 10th edition.” The patient showed no recurrence sign 12 months after the surgery.The current study also reviewed 35 EACC cases reported in Japanese literatures from 1990 to 2014. Combined with our case, we found that EACC is less frequently accompanied by lymph node metastasis as compared to esophageal squamous cell carcinoma, especially at the early stage. The prognosis of EACC is relatively better when tumors have no lymph node metastasis.

Successful resection of esophageal carcinosarcoma in presence of right aortic arch: a case report

We herein report a giant esophageal carcinosarcoma (ECS) occupying the entire intrathoracic esophagus with a coexisting right aortic arch (RAA). The patient was admitted with severe dysphagia and weight loss. Subtotal esophagectomy was performed via left thoraco-cervical approach with cervical esophagogastric anastomosis. The aortopulmonary ligament was ligated and dissected at first for better exposure. Patient recovered uneventfully and there was no evidence of recurrence during the 1 year follow-up period. To our knowledge, this is the first report of such a giant ECS with coexisting RAA. For this kind of patient, a left thoracotomy approach and cervical anastomosis is recommended, and the dissection of aortopulmonary ligament is usually required.

SIEWERT I TYPE ESOGASTRIC JUNCTION ADENOCARCINOMA - COMPLETE THERAPEUTIC RESPONSE AFTER NEOADJUVANT TREATMENT

The adenocarcinoma of the esogastric junction is a neoplasia with growing frequency in both US and Europe. We present a case study of a 43-year-old patient, smoker, that presented for the installation of dysphagia for both solids and liquids, weight loss (10 kg / 6 months), marked asthenia. Upper digestive endoscopy: starting from 32 cm from the dental arch, stenosing, budding tumoral formation, stretching up to the esogastric junction. Biopsies confirm the presence of moderately differentiated adenocarcinoma. Endoscopically, a metallic expandable esophageal stent is installed. PET-CT: important irregular parietal thickening with increased activity in the lower level of the thoracic esophagus, extending on the lesser curvature of the stomach; increased para esophageal lymph nodes (17 / 21cm) without increased metabolic activity, 2 node images with slightly increased activity. Neoadjuvant treatment is started using induction chemotherapy in order to trigger the sensitivity of the tumor, followed by targeted radiotherapy. The patient's condition is reassessed 6 weeks after neoadjuvant chemo radiotherapy and then surgery is practiced - subtotal esophagectomy with resection of the gastric lesser curvature by McKeown triple approach, 3 field lymphadenectomy, AKIYAMA type gastric pull-up, pyloroplasty, feeding jejunostomy. The histopathology of the resected specimen shows complete pathological response. The postoperative evolution is favorable, despite the fact that on the 5th postoperative day a respiratory complication occurs, bronchopneumonia, which is resolved under antibiotic treatment. Six months postoperatively, the patient shows no sign of loco-regional or distant relapse.

Synchronous double primary cancer of the esophagus and ampulla of Vater successfully treated by a two-stage operation: report of a case

A 68-year-old man was diagnosed with local recurrent cancer of the ampulla of Vater by follow-up endoscopy 3 years after an endoscopic papillectomy. A screening endoscopy found superficial middle thoracic esophageal cancer. The patient required an esophagectomy and pancreatoduodenectomy. We chose a two-stage operation for the esophageal cancer and the local recurrent cancer of the ampulla of Vater, both to reduce surgical invasiveness and to circumvent the lower curability. The first-stage operation consisted of a right transthoracic subtotal esophagectomy with mediastinal and cervical lymph node dissection, external esophagostomy of the neck, and gastrostomy. Forty days after the first surgery, a gastroduodenal artery- and right gastroepiploic vessel-preserving pancreatoduodenectomy with Child’s reconstruction was performed as the second-stage surgery. Esophageal reconstruction was achieved using a gastric tube via the percutaneous route with vascular anastomosis.

The Prognostic Relevance of Subcarinal Lymph Node Dissection in Esophageal Squamous Cell Carcinoma.

The objective of this study was to evaluate the prognostic relevance of subcarinal lymph node dissection in patients with esophageal squamous cell carcinoma (ESCC) and to identify a subset of patients in whom subcarinal lymph node dissection can be omitted. We retrospectively analyzed 342 consecutive patients with thoracic ESCC who underwent R0 subtotal esophagectomy. All patients underwent subcarinal lymph node dissection. The efficacy index (frequency of metastasis to a particular lymph node station multiplied by the 5-year disease-specific survival rate of patients with metastasis to the station) was calculated for the subcarinal lymph node station, and the prognostic impact of dissecting this station was estimated with reference to the main tumor location. Independent predictive factors for pathological subcarinal lymph node metastasis were analyzed using a proportional hazards model. The overall frequency of metastasis to the subcarinal lymph nodes was 7.0 % (2.4, 8.9, and 5.8 % in patients with upper, middle, and lower thoracic ESCC, respectively). The efficacy index for the middle thoracic esophagus was 2.9, and that for the upper and lower thoracic esophagus was 0.0. The 5-year disease-free survival rate was significantly lower in patients with pathological subcarinal lymph node metastasis than those without (23.1 vs. 67.5 %, respectively; log-rank p < 0.0001). In multivariate analysis, clinical T stage (T2-T4) was the independent predictive factor for pathological subcarinal lymph node metastasis (p = 0.021). Subcarinal lymph node dissection might have little value in patients with upper and lower thoracic ESCC and could be omitted, especially for superficial carcinoma.

Radical Lymph Node Dissection in Primary Esophagectomy for Esophageal Squamous Cell Carcinoma

Subtotal esophagectomy with radical lymph node dissection (RLND) remains an effective therapeutic strategy for localized esophageal squamous cell carcinoma (ESCC). However, controversy exists regarding the extent to which RLND should be performed. We reappraised the prognostic impact and accurate nodal staging of RLND in ESCC. The data from 101 ESCC patients (mean age, 57.5 years; 93 men) who underwent primary subtotal esophagectomy were retrospectively collected. Candidate variables, including the number of total dissected lymph nodes (TDLN [subgrouped into TDLN less than 13, TDLN 13 to 40, and TDLN more than 40]), were evaluated to determine their prognostic impacts and hazard ratio (HR). Fewer TDLN (p < 0.001; HR 9.011, 2.449, and 1.000 for TDLN less than 13, TDLN 13 to 40, and TDLN more than 40, respectively), tumor length exceeding 3.5 cm (p < 0.001; HR 3.321), resection margin invasion (p < 0.001; HR 14.493), and positive nodal status (p = 0.002; HR 2.730) were independent predictors of a poor prognosis. Considering the 54 node-negative patients, more TDLN correlated with improved survival (p = 0.001). Risk analysis demonstrated that one fewer TDLN could contribute to an increased HR of 1.047 (p = 0.014). However, RLND involving more TDLN appeared to lose the prognostic impact for the 47 node-positive patients (p = 0.072). Furthermore, the number of positive dissected lymph nodes remained at approximately 4 if the number of TDLN exceeded 20. For N-negative or N-positive ESCC patients undergoing primary surgical resection, the number of TDLN influenced their prognosis or nodal staging accuracy, respectively. At least 20 TDLN were necessary for N-positive patients.

Treatment of oesophageal perforations and its complications (Mediastinitis, abscess) with covered metal stent and drainage

Introduction: The covered metal stents were first used for malignant oesophageal stenosis. Since 2007 we have used it 15 times for treatment of oesophageal perforations and post-operative leaks. Methods and patients: When the perforation or leakage was recognised the decision on the ways of therapy was done after consultation with an oesophageal surgeon. The optimal size of retrievable covered metal stent was calculated individually. The stenting was supplemented in most cases with drainage, and with antibiotic treatment in an intensive care unit. The timing of stent removal (in most cases 6 – 10 weeks) was after individual consideration. The indications for stenting were: iatrogenic perforation in corrosive stenosis in 4 cases; Boerhaave's syndrome in 2 cases; postoperative leakage in 6 cases; oesophagus defect after thyroid surgery in 1 case and thoracic empyema with oesophageal fistula in 2 cases. Results: The oesophageal defect was sailed in all 15 cases. One patient died as a result of a non-related disease – severe lung destruction and aspergillosis. Twelve oesophagus defects were healed from 14 patients. In one case, with operated Boerhaave's syndrome, the inveterate fistula persisted. In another case, the septic patient with Boerhaave's syndrome was treated with drains and late stenting. After medical stabilization two (residual) mediastinal abscesses were left; they were not drained by the referring hospital despite our request. After removing the stent we observed 2 fistulae. After subtotal oesophagectomy substernal a gastric tube bypass was performed. Conclusion: Early stenting and drainage is a safe, effective and less invasive treatment of oesophageal perforation and leakage with low mortality.

Prevalence and management of colorectal neoplasia in surgically treated esophageal cancer patients

AimsThe existence of other primary tumors during the treatment of esophageal cancer patients has been an important issue. Our aim is to investigate the prevalence and management of colorectal neoplasia (CRN) in surgically treated esophageal cancer patients. MethodsBetween 2002 and 2008, 93 patients with esophageal cancer were surgically treated. Seventy-three patients underwent subtotal esophagectomy and 20 underwent lower esophagectomy for esophageal cancer. Colonoscopy was available for detecting CRN before and after surgery. ResultsEighty-nine (95.7%) of the 93 patients were screened by colonoscopy preoperatively or within a year from the operation. Thirty-nine patients (43.8%) with CRN were synchronously identified: adenoma in 34 (38.2%) and adenocarcinoma in 5 patients (5.6%). Eleven adenomas with high grade-dysplasia and 8 adenomas with low grade-dysplasia were removed endoscopically. Three superficial adenocarcinomas were endoscopically removed before surgery, and 2 adenocarcinomas were surgically removed. Seventy-four patients (83.1%) were followed using colonoscopy, and 11 subsequent CRN, including 2 superficial adenocarcinomas, were endoscopically detected in 8 patients (10.8%). The size of esophageal cancer was larger in the patients with than without CRN (p = 0.036). The body mass index in esophageal cancer patients with CRN tended to be higher than in those without CRN (p = 0.065). ConclusionsWe noted that esophageal cancer is frequently associated with synchronous and/or metachronous colorectal cancer and adenomas. Colonoscopy is useful to detect and manage CRN before and after esophagectomy, although a few limitations exist.

Minimally Invasive Esophagectomy with Right Bronchial Occlusion under Artificial Pneumothorax

Aims: To assess the safety and feasibility of minimally invasive esophagectomy and selected three-field lymphadenectomy with the right bronchial occlusion in left semi-prone position under artificial pneumothorax. Methods: Thoracoscopic-laparoscopic subtotal esophagectomy and selected three-field lymphadenectomy were performed in 166 patients with esophageal carcinoma by the right bronchial occlusion in left semi-prone position under artificial pneumothorax. Results: 109 patients received two-field lymphadenectomy and 57 received three-field lymphadenectomy. The average operative time was 202.5 ± 21.3 min; the average thoracoscopic operative time was 98.4 ± 15.5 min. The average blood loss was 39.6 ± 4.2 ml, and no blood transfusion was needed during the surgery. The mean lymph node harvest was 28.4 ± 5.2 nodes. Hospital stay ranged from 7 to 95 days and the average was 11.3 days. The postoperative complication rate was 29.5%, and the mortality rate was 1.2%. Conclusions: It is feasible and safe to perform thoracoscopic-laparoscopic subtotal esophagectomy and selected three-field lymphadenectomy with the right bronchial occlusion in left semi-prone position under artificial pneumothorax for esophageal carcinoma. The procedure shows advantages in improved visibility and accessibility of the surgical field, and better subsequent surgical outcomes.
