Laparoscopic ischemic conditioning of the stomach prior to esophagectomy

Several complications after esophagectomy with gastric pull‐up are associated with ischemia within the gastric conduit. The aim of this study is to assess the feasibility of laparoscopic ischemic preconditioning of the stomach prior to thoracotomy, esophagectomy, and gastric pull‐up with an intrathoracic anastomosis. A retrospective review of 24 consecutive patients between October 2008 and July 2011 with esophageal adenocarcinoma (stage I–III) undergoing laparoscopic gastric ischemic conditioning prior to esophagectomy was conducted. Conditioning included laparoscopic ligation of the left and short gastric arteries, celiac node dissection, and jejunostomy tube placement. Formal resection and reconstruction was then performed 4–10 days later. Of the 24 patients, 88% received neoadjuvant chemotherapy/radiation therapy. Twenty‐three of the 24 patients underwent successful laparoscopic ischemic conditioning and subsequent esophagectomy. Total mean number of lymph nodes harvested was 21.8 (±8.0), and a mean of 5.3 (±2.4) celiac lymph nodes identified. There were no conversions to an open procedure. Length of stay was 3.8 (±4.8) days with a median length of stay of 2 (1–24) days. Three patients experienced anastomotic leak, six patients experience delayed gastric emptying, and two patients developed anastomotic stricture. There were no surgical site infections. R0 resection was achieved in all patients who underwent laparoscopic ischemic conditioning followed by esophagectomy. Laparoscopic ischemic conditioning of the gastric conduit has been shown to be feasible and safe.     

Metachronous cancer of gastroplasty after esophagectomy

We reviewed two cases of adenocarcinoma of the gastric tube used for reconstruction after esophagectomy for cancer. The first case gastric cancer was detected during follow-up by endoscopic examination. Total resection of the gastric tube and reconstruction by Roux-en-Y was performed each time. The patient was alive and disease-free 1 year after surgery. In the second case the tumor was revealed via thoracic pain. Chemotherapy, using carboplatin-5-fluorouracil, was performed because of lung metastasis but the patient died 1 year later. The incidence of gastric tube cancer after esophagectomy has recently increased in conjunction with the lengthening of survival of esophageal cancer patients. The clinical symptoms related to tumors are associated with short-term survival, whereas the cancers detected by routine endoscopy screening have occasional long-term survival. Gastrectomy is proposed for surgical treatment but the operating procedure is complex with a high morbidity rate. Lesions detected at an early stage could be treated by minimally invasive surgery such as endoscopic mucosal resection.     

Management of gastric epithelial neoplasia in patients requiring esophagectomy for esophageal cancer

Esophageal squamous cell carcinoma is occasionally associated with malignancies located in other regions of the alimentary tract, as well as in the head, neck, and upper respiratory tract. The stomach is most commonly used for reconstruction of the alimentary tract after esophagectomy for esophageal cancer. When synchronous tumors are located in the stomach, it is often unsuitable for use in esophageal reconstruction. In such cases, an invasive procedure involving anastomosis between the esophagus and the colon must be performed. However, this procedure is associated with a high incidence of mortality and morbidity. Seven patients with synchronous esophageal cancer and gastric epithelial neoplasia were encountered. First, endoscopic submucosal dissection (ESD) was performed for the gastric epithelial neoplasia. Then, following successful ESD, Ivor‐Lewis esophagectomy for esophageal cancer was planned 1 to 2 weeks later. A total of 11 gastric epithelial lesions were found in seven patients. En bloc resection by ESD was possible in all 11 lesions and histologically complete resection was achieved in all 11 lesions. Follow‐up endoscopy was done 1–2 weeks after ESD; six patients with well‐healing ulcers underwent esophagectomy the next day (8 or 15 days after ESD). In one patient with a poorly healed ulcer, a second follow‐up endoscopy was done 1 week later and then esophagectomy was performed the next day (22 days after ESD). Post‐surgical complications related to ESD, such as bleeding or mediastinal leak, were not seen in any of the seven patients. In patients with synchronous esophageal cancer and gastric epithelial neoplasia, ESD for gastric epithelial neoplasia followed by Ivor‐Lewis esophagectomy 1 to 2 weeks later is an effective choice of treatment.     

An exceptional postoperative gastric tube bleeding after esophageal resection for cancer

A case of gastric tube bleeding after an Ivor-Lewis esophagectomy with gastroesophageal anastomosis is reported. During the early postoperative course, the patient had a gastric tube stasis that improved progressively. The subsequent onset of a serious and intermittent hematemesis, which was endoscopically deemed to be the result of a hemorrhagic gastritis, required multiple blood transfusions. The evolution to a severe hemodynamic instability obliged us to reoperate on the patient. During surgery, a band-related obstruction of the first jejunal loop with local signs of vascular hypertension was noted. As soon as the obstruction was solved, the gastric bleeding stopped. The authors discuss the clinical aspects and physiopathology of the gastric tube bleeding and, in particular, they evaluate the influence of the intestinal obstruction with vascular involvement on the development of this exceptional and severe complication.     

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.     

Two-step method for creating a gastric tube during laparoscopic-thoracoscopic Ivor-Lewis esophagectomy

AIM To introduce a two-step method for creating a gastric tube during laparoscopic-thoracoscopic Ivor-Lewis esophagectomy and assess its clinical application.METHODS One hundred and twenty-two patients with middle or lower esophageal cancer who underwent laparoscopicthoracoscopic Ivor-Lewis esophagectomy at Liaoning Cancer Hospital and Institute from March 2014 to March 2016 were included in this study,and divided into two groups based on the procedure used for creating a gastric tube. One group used a two-step method for creating a gastric tube,and the other group used the conventional method. The two groups were compared regarding the operating time,surgical complications,and number of stapler cartridges used.RESULTS The mean operating time was significantly shorter in the two-step method group than in the conventional method group [238(179-293) min vs 272(189-347) min,P 0.01]. No postoperative death occurred in either group. There was no significant difference in the rate of complications [14(21.9%) vs 13(22.4%),P= 0.55] or mean number of stapler cartridges used [5(4-6) vs 5.2(5-6),P = 0.007] between the two groups.CONCLUSION The two-step method for creating a gastric tube during laparoscopic-thoracoscopic Ivor-Lewis esophagectomy has the advantages of simple operation,minimal damage to the tubular stomach,and reduced use of stapler cartridges.     

Efficacy and safety of endoscopic submucosal dissection for gastric tube cancer: A multicenter retrospective study

BACKGROUNDRecent improvements in the prognosis of patients with esophageal cancer have led to the increased occurrence of gastric tube cancer (GTC) in the reconstructed gastric tube. However, there are few reports on the treatment results of endoscopic submucosal dissection (ESD) for GTC.AIMTo evaluate the efficacy and safety of ESD for GTC after esophagectomy in a multicenter trial.METHODSWe retrospectively investigated 48 GTC lesions in 38 consecutive patients with GTC in the reconstructed gastric tube after esophagectomy who had undergone ESD between January 2005 and December 2019 at 8 institutions participating in the Okayama Gut Study group. The clinical indications of ESD for early gastric cancer were similarly applied for GTC after esophagectomy. ESD specimens were evaluated in 2-mm slices according to the Japanese Classification of Gastric Carcinoma with curability assessments divided into curative and non-curative resection based on the Gastric Cancer Treatment Guidelines. Patient characteristics, treatment results, clinical course, and treatment outcomes were analyzed.RESULTSThe median age of patients was 71.5 years (range, 57-84years), and there were 34 men and 4 women. The median observation period after ESD was 884 d (range, 8-4040 d). The median procedure time was 81 min (range, 29-334 min), the en bloc resection rate was 91.7% (44/48), and the curative resection rate was 79% (38/48). Complications during ESD were seen in 4% (2/48) of case, and those after ESD were seen in 10% (5/48) of case. The survival rate at 5 years was 59.5%. During the observation period after ESD, 10 patients died of other diseases. Although there were differences in the procedure time between institutions, a multivariate analysis showed that tumor size was the only factor associated with prolonged procedure time.CONCLUSIONESD for GTC after esophagectomy was shown to be safe and effective.     

Gastroventricular fistula: severe complication of posterior mediastinal gastric tube reconstruction after esophagectomy

A case of gastroventricular fistula following resection of cancer of the midesophagus and reconstruction using a gastric tube via the retromediastinal route is presented. Given that a peptic ulcer occurring in the gastric tube can perforate into any adjacent structures, gastroventricular fistula is one of the most lethal complications after esophagectomy.     

Clinical characteristics and management of gastric tube cancer with endoscopic submucosal dissection

AIM:To identify the characteristics of gastric tube cancer(GTC) and the complications associated with endoscopic submucosal dissection(ESD) for GTC.METHODS:Between 2007 and 2012,11 individualswith early gastric cancer in the reconstructed gastric tube after esophagectomy who underwent ESD in this hospital were studied.The characteristics of GTC were identified,and the complications of ESD for GTC were analyzed at three phases:preoperative,intraoperative,and postoperative.RESULTS:A total of 11 consecutive patients with 11 GTCs were selected for this study.All cases underwent en bloc resections by ESD.The median procedure time was 142 min.The average GTC diameter was 26.1 mm,and the average size of the resected lesions was 45.5 mm.The histopathological diagnosis in all cases was a differentiated adenocarcinoma.In the preoperative phase,anastomotic strictures(5/11,45%) and food residues(4/11,36.4%) in the gastric tube were the main complications.In the intraoperative phase,bleeding was observed in 5 cases(45%).The postoperative complications observed were delayed bleeding in 2 cases(18.2%) and stenosis in one case(9.1%).The case with stenosis was successfully treated using endoscopic balloon dilatation.CONCLUSION:Minor complications were frequently observed.However,all GTCs underwent en bloc resection with ESD without any serious complications.ESD is considered a useful treatment for GTC.     

Gastric endoscopic submucosal dissection via gastrostoma before the second operation for esophageal perforation: A case report

A 69-year-old man with advanced esophageal cancer and 2 early gastric cancers received chemoradiotherapy and was scheduled to undergo subtotal esophagectomy after gastric endoscopic submucosal dissection(ESD). However, left lower esophageal perforation induced by vomiting suddenly occurred, and he urgently underwent esophago-proximal gastrectomy and gastrostomy without reconstruction. The resected specimen showed a complete response of pretreatment for the esophageal cancer and radical resection of one gastric cancer. Radical resection of the other gastric lesion was necessary before reconstruction. The fistula of gastrostoma was gradually dilated from 6.7 to 9.3 mm in order to pass the endoscope. At nine months after emergent operation, gastric ESD was performed via only the gastrostoma. A hemoclip with thread was attached to the specimen, and the thread was pulled out of the gastrostoma. The specimen was able to be removed en bloc, resulting in radical resection. Gastric tube reconstruction through the posterior sternal route was performed at six months after the ESD. He has not developed recurrence of the esophageal or gastric cancer in the two years since the emergent operation.     

Prospective endoscopic follow-up results of reconstructed gastric tube

BACKGROUND/AIMS: Recent advances in the treatment of esophageal cancer have afforded better prognosis for patients. Despite the increased need to monitor the progress of patients with reconstructed digestive tracts over the long-term, no reliable prospective studies have yet been conducted. This prospective study determined secondary disease of the reconstructed gastric tube after esophagectomy for esophageal cancer. METHODOLOGY: One hundred and fourteen patients who underwent esophagectomy and reconstructed gastric tube via the posterior mediastinal route between April 1992 and March 1999 at Akita University Hospital, were followed up. Follow-up endoscopy was carried out once a year to determine the incidence and characteristics of secondary disease of the reconstructed gastric tube. RESULTS: Fifty-four (47%) patients were found to have secondary gastric abnormalities. Of these, 4 patients (3.5%) had carcinoma of the gastric tube, 12 patients (10.5%) had benign gastric tumor, 7 patients (6.1%) had gastric ulcers, and 40 patients (35.1%) had erosive or hemorrhagic gastritis. Three patients found to have early gastric cancer upon periodic follow-up endoscopy underwent successful complete resections. CONCLUSIONS: Annual follow-up endoscopy is vital to the detection of early, curative secondary gastric cancer and ulceration in patients following esophagectomy for esophageal cancer.     

Gastropericardial fistula resulting from ulcerative perforation of the reconstructed gastric tube after surgery for esophageal cancer

Gastropericardial fistulae are rare and may cause fatal complications such as acute purulent carditis and cardiac tamponade. The present report describes a case of a gastropericardial fistula caused by a peptic ulcer perforating a retrosternal reconstructed gastric tube 2 years after subtotal esophagectomy for esophageal cancer. Surgical intervention involved left thoracotomy, pericardium fenestration, and drainage of the pericardium and left thoracic cavity. The patient suffered postoperative complications including septic shock, acute respiratory distress syndrome, and cardiac insufficiency; however, he recovered after successful surgical intervention. In this case, the withdrawal of proton pump inhibitors and the patient’s sustained drinking habit after esophageal replacement surgery may have caused peptic ulcers in the gastric tube. Early diagnosis and surgical treatment of gastropericardial fistulae are essential to avoid fatal complications.     

A new operative technique for the resection of gastric tube cancer by means of lifting the anterior chest wall and videoscope-assisted surgery

SUMMARY.  The prolonged survival of patients receiving surgery for esophageal cancer has led to an increased incidence of adenocarcinoma arising in the gastric tube used for reconstruction (gastric tube cancer). In patients with advanced gastric tube cancer, resection of the gastric tube should be considered, but currently available procedures are very invasive. In patients undergoing curative surgery for gastric tube cancer that has developed after reconstruction through the retrosternal route, the gastric tube is usually resected through a median sternotomy, followed by reconstruction with the colon. However, postoperative complications often occur and treatment outcomes remain poor. We developed a new surgical technique for gastric tube resection without performing a sternotomy in patients with gastric tube cancer who had previously undergone reconstruction through the retrosternal route. Our technique was used to treat two patients. Two Kirschner wires were passed subcutaneously through the anterior chest; the chest was lifted to extend the retrosternal space and secure an adequate surgical field. The stomach was separated from the surrounding tissue under videoscopic guidance. Total resection of the gastric tube was done. The retrosternal space was used to lift the jejunum. Roux-en-Y reconstruction was performed. Neither patient had suture line failure or surgical site infection. Their recovery was uneventful. Our surgical technique has several potential advantages including (i) reduced surgical stress; (ii) the ability to use the retrosternal space for reconstruction after gastric tube resection; and (iii) a reduced risk of serious infections such as osteomyelitis in patients with suture line failure. Our findings require confirmation by additional studies.     

Ten cases of gastro‐tracheobronchial fistula: a serious complication after esophagectomy and reconstruction using posterior mediastinal gastric tube

Gastro‐tracheobronchial fistula (GTF) is a rare but life‐threatening complication specifically observed after esophagectomy and reconstruction using posterior mediastinal gastric tube. Ten cases of GTF were encountered in three hospitals in 2000–2009. Their clinicopathological, surgical, and postoperative care are summarized, together with a review of previously reported cases. GTF was classified as anastomotic leakage (n= 5), gastric necrosis (n= 4), and gastric ulcer type (n= 1). The anastomotic leakage type appeared about 2 weeks (postoperative day [POD]: 8–35) after esophagectomy, was located in the cervical or higher thoracic trachea. Breathing and pneumonia were controlled by tracheal tube placed in the distal of fistula. The gastric necrosis type was noted in patients who developed necrosis of the upper part of the gastric tube and abscess formation behind the tracheal wall, at POD 20–36 around the carina, the site of pronounced ischemia. Due to the large fistula around the carina, emergency surgery with muscle patch repair was frequently required for the control of aspiration pneumonia. Patients of the gastric ulcer type had peptic ulcer in the lesser curvature of the gastric tube, which perforated into the right bronchus long after surgery (POD 630). With respect to tracheobronchial factors, preoperative chemoradiation (three cases) and pre‐tracheal node dissection (three cases) tended to increase the risk of GTF. Closure of GTF by surgery (muscle patch repair) was successful in four cases and by nonsurgical treatment in three cases. In one case, stable oral intake was achieved by bypass operation without closure of GTF. Hospital death occurred in three cases. Understanding the pathogenesis and treatment options of GTF is important for surgeons who deal with esophageal cancer.     

One-stage radical operation of aortoesophageal fistula -combination of VATS esophagectomy and open aortic surgery: report of a case

Aortoesophageal fistula is a rare but fatal disease of thoracic surgery. We present a case of a 74-year-old male with aortoesophageal fistula. The patient underwent successful one-stage surgical treatment by video-assisted esophagectomy with esophageal reconstruction by gastric conduit and open aortic graft replacement subsequent to a temporary thoracic endovascular aortic repair.     

A rare case of retro-hepatic inferior vena caval leiomyosarcoma – Computed tomography,surgical and intraoperative echocardiography imaging

Leiomyosarcoma of retro-hepatic portion of inferior vena cava (IVC) is a rare vascular tumor with poor prognosis if adequate surgical resection is not achieved. Surgical repair includes dissection of the tumor and reconstruction of the IVC with a tube graft. Establishing a normal flow and gradient in IVC and hepatic veins is imperative for a successful repair. We report a case of retro hepatic IVC leiomyosarcoma where the preoperative computed tomography described the anatomy and extension of the tumor whereas intraoperative transesophageal echocardiography helped in the assessment of adequacy of surgical repair.     

Curative resection of gastric tube cancer by hand-assisted thoracoscopic surgery

We report a 78-year-old male who underwent successful resection of a gastric tube cancer by hand-assisted thoracoscopic surgery. The patient was initially placed in the supine position, and the abdominal portion of the gastric tube was mobilized via upper midline laparotomy. A pedicled colonic graft supplied by the left colic artery was prepared. The patient was then moved to the left decubitus position, and five ports were placed in the right chest wall. The surgeon stood in front of the patient, and inserted his left hand into the right pleural cavity through the laparotomy incision. After the whole gastric tube was successfully mobilized, the patient was returned to the supine position. The gastric tube was reconstructed with the pedicled colonic graft via the subcutaneous route. The surgical resection margins were free of cancer. The patient currently survives more than 16 months after surgery.     

Squamous Cell Carcinoma in a Large Epiphrenic Esophageal Diverticulum

Carcinoma is rare in an esophageal diverticulum. The case of a 53-year-old man with a large mass in a long-standing symptomatic epiphrenic esophageal diverticulum is presented in this study. Squamous cell carcinoma in the diverticulum with pleural invasion was diagnosed after surgical diverticulectomy. The patient underwent subtotal esophagectomy with locoregional lymph node dissection and reconstruction with gastric tube because of micro-invasion at the surgical margin. The patient developed malignant pleural effusion at 6 months after surgery, and he eventually expired 3 months later. Carcinoma can develop in esophageal diverticula and is usually diagnosed at an advanced stage with poor prognosis.     

Synchronous esophageal and renal cell carcinoma

Multiple cancer associated with esophageal cancer is not uncommon; however, synchronous esophageal and renal cell carcinoma is very rare. Only three cases have been reported to date, and one of these patients was treated in our institution. We have since successfully treated another patient. Here, we report the two cases treated in our institution. In the first case, esophagectomy, nephrectomy, and reconstruction using a gastric tube were carried out in one stage. Post-operative renal function was temporarily impaired by the complications of anastomotic leakage and pyothorax but no hemodialysis was needed. In the second case, as the patient had undergone distal gastrectomy because of gastric cancer, we chose a two-stage operation, i.e. esophagectomy and nephrectomy as the first stage, followed by reconstruction using a colon substitute after 4 weeks, resulting in only slight renal dysfunction. Patients 1 and 2 are alive and well 7 years and 2 years after the operations respectively.
