Long-Term Outcomes of the Treatment for Gastric Tube Cancer After Esophagectomy for Esophageal Cancer

BACKGROUND

The long-term outcomes of gastric tube cancer (GTC) are unclear. This study therefore aimed to clarify clinicopathologic features and the long-term outcomes of patients with GTC.

METHODS

The 25 patients who were diagnosed with GTC between April 2003 and December 2022 at our hospital were eligible for inclusion in this retrospective study, and this included 27 lesions. We retrospectively evaluated clinicopathologic factors based on hospital records.

RESULTS

In our cohort, 88% of incidences of GTC were located in the middle or lower gastric tube. As the treatment of GTC, we used endoscopic submucosal dissection, gastrectomy, chemoradiotherapy, chemotherapy, and best supportive care for 16 (59%), 6 (22%), 1 (4%), 1 (4%), and 3 (11%) lesions, respectively. Perforation after endoscopic submucosal dissection was observed in 6 of the 16 lesions. Partial gastric tube resection was performed for 3 patients and total gastric tube resection was performed for 3 patients. One patient who underwent total gastric tube resection died due to acute respiratory distress syndrome. In survival analysis, the 3-year overall survival rate was 52% and the 3-year disease-specific survival rate was 74%. Five patients (20%) died of aspiration pneumonia, 2 patients (8%) of another disease, and 1 patient (4%) of another type of cancer. According to multivariate analysis, independent prognostic factors for overall survival were cN status (HR, 18.021; P=0.004) and complication of aspiration pneumonia (HR, 8.373; P=0.004).

CONCLUSIONS

The occurrence of aspiration pneumonia and cN status were prognostic factors after the treatment for GTC. Assessment of dysphagia and surveillance after treatment for GTC are important to improve the prognosis.

Successful Robot-Assisted Surgery for Advanced Metachronous Cancer in a Gastric Conduit after Esophagectomy: A Case Report

The incidence of gastric tube cancers has increased due to improved survival rates in patients after esophagectomy. However, the optimal surgical approach for gastric tube cancer remains controversial. Here, we report the case of a 70-year-old man with advanced gastric cancer arising from a retrosternally placed gastric conduit, 12 years after thoracic esophagectomy for esophageal cancer. Total resection of the gastric conduit was performed with robotic assistance. Although the working space was limited, secure resection was possible. Continuous en bloc mobilization was achieved with neck dissection, and reconstruction was performed via the same retrosternal route using the ileocolon. The patient was discharged on the 14th postoperative day without any adverse events. Robot-assisted surgery can overcome the technical limitations of laparoscopic mediastinal surgery and has advantages such as improved ergonomics, comfort, and elimination of hand tremors, and therefore may be an option for future minimally invasive surgeries.

Comparative analysis of the outcomes of gastrectomy vs. endoscopic mucosal resection or endoscopic submucosal dissection for the treatment of gastric tube cancer after esophagectomy

This study investigated the clinical characteristics of patients with gastric tube cancer following esophagectomy at our hospital, and to examine the outcomes of gastrectomy versus endoscopic submucosal dissection. Of 49 patients who underwent treatment for gastric tube cancer that developed 1 year or more after esophagectomy, 30 patients underwent subsequent gastrectomy (Group A), and 19 patients underwent endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) (Group B). The characteristics and outcomes of these two groups were compared. The interval between esophagectomy and diagnosis of gastric tube cancer ranged from 1 to 30 years. The most common location was the lesser curvature of the lower gastric tube. When the cancer was detected early, EMR or ESD was performed, and the cancer did not recur. In advanced tumors, gastrectomy was performed but the gastric tube was difficult to approach and lymph node dissection was difficult; two patients died as a result of the gastrectomy. In Group A, recurrence occurred most often as axillary lymph node, bone, or liver metastases; in Group B, no recurrence or metastases were observed. In addition to recurrence and metastasis, gastric tube cancer is often observed after esophagectomy. The present findings highlight the importance of early detection of gastric tube cancer after esophagectomy and that the EMR and ESD procedures are safe and have significantly fewer complications compared with gastrectomy. Follow-up examinations should be scheduled with consideration given to the most frequent sites of gastric tube cancer occurrence and the time elapsed since esophagectomy.

Left thoracoscopic approach in the supine position for torsion of the residual esophagus after esophagectomy: a case report

Background

Anastomotic stenosis can occur after esophagectomy and gastric tube reconstruction. The effective surgical treatment for refractory anastomotic stenosis, which seems difficult to resolve with endoscopic treatment, has not been established. We report a case of refractory stenosis due to esophageal torsion in which reconstructive surgery was possible using a left thoracoscopic approach in the supine position.

Case presentation

A 72-year-old man who underwent thoracoscopic subtotal esophagectomy and retrosternal gastric tube reconstruction for esophageal cancer 6 months previously presented to us. Postoperative endoscopy revealed that the residual esophagus was twisted approximately 360°, just above the anastomotic site. Conservative endoscopic treatment failed to improve the condition due to severe passage obstruction, and reconstructive surgery was repeated. Surgery was performed in the supine position using a left thoracoscopic approach. The entire circumferences of the gastric tube and residual esophagus were dissected from the inferior mediastinum to the top of the sternum, with focus on preserving the right gastroepiploic vein and gastric-tube wall. Subsequently, laparoscopic surgery was performed to remove the gastric tube from the thoracoabdominal junction. After separating the esophagus on the oral side of the torsion from the left cervical wound, the abdomen was opened, the gastric tube was pulled out through the abdominal wound, and adhesions in the abdominal cavity were peeled off to raise the gastric tube cranially via the retrosternal route. An end-to-side anastomosis was performed using a circular stapler, and the esophageal torsion and previous anastomosis were resected. Oral intake was resumed on the 7th postoperative day, and the patient was discharged on the 38th day.

Conclusions

After subtotal esophagectomy and retrosternal gastric tube reconstruction, the left thoracoscopic approach is one of the most minimally invasive approaches and is especially useful for preserving the right gastroepiploic artery and veins and for mobilizing the gastric tube wall.

Metachronous carcinoma of the gastric tube following tumour-associated oesophagectomy

INTRODUCTION

The prognosis of oesophageal carcinoma has improved during the last years. Thereby, the increasing survival has led to increasing occurrence of secondary gastric tube carcinoma (gastric conduit cancer, GTC) following oesophageal tumour resection.

MATERIAL AND PATIENTS

A literature review (EMBASE, PubMed), spanning the years 2000 to 2020, identified 342 patients worldwide with a GTC following tumour-related oesophagectomy, of which 306 patients could be included for further analysis.

RESULTS

The median age of 306 patients with GTC was 66.4 (39-80) years. 91.2% of patients (n = 279) were male. The median interval between oesophagectomy and GTC was 60.3 (4-236) months. 73.8% of patients (n = 226) were diagnosed as early cancer (EGC, T1) and 26.2% as advanced carcinoma (AGC, > T2; n = 80). Primary oesophagectomy was performed in 97.4% of patients (N = 298) for squamous cell carcinoma. AEG I carcinoma was present in only 5 patients (1.6%). In contrast, 99% (n = 303) of the GTC were found to be adenocarcinomas. One hundred eighty patients (58.8%) could be treated by endoscopic resection (ER). R0 resection was achieved in 82.8% (n = 149). The complication rate was 13.3% (n = 24) and the 30-day mortality 1.1% (n = 2) for ER. Eighty-three patients (27.1%) were treated surgically. These included 13 wedge resections, 25 partial resections and 45 total gastric graft resections with predominantly colon interposition. The R0 rate was 98.8% (n = 82). The postoperative morbidity was 24.1% (n = 20); the 90-day mortality was 6% (n = 5). In 43 patients (14%), palliative chemotherapy or radiotherapy or best supportive care took place. GTC diagnosed early in the EGC stage can be safely managed with ER. In cases of advanced GTC, surgical resection can be a potentially curative approach. Survival times of up to 120 months have been described after intervention for GTC.

A novel laparoscopic assisted mediastinal dissection with gastric tube inversion technique for gastric tube cancer reconstructed through a retrosternal route

A median sternotomy is often performed in patients with gastric tube cancer reconstructed through the retrosternal route; however, this procedure is invasive and has the risk of severe infectious complications. To overcome these problems, we created a novel method to perform the reconstructed gastric tube resection using a gastric tube inversion technique combined with a laparoscopic mediastinal approach. After the duodenum was divided, the oral side of the cut end was sutured with silken threads for traction. The gastric tube was dissected from the caudal side under a laparoscopic mediastinal approach, whereas the cervical esophagus was taped. After the adhesion between the middle side of the posterior sternum and the reconstructed gastric tube was dissected to the cervix, the gastric tube was inverted by guiding and pulling the thread toward the cervical side. Sharp dissection was facilitated between the inverted gastric tube and the surrounding organs under moderate traction and a favorable surgical view. We have performed this procedure and evaluated the short-term outcomes in six cases. The laparoscopic mediastinal approach was completed without a median sternotomy in all six cases. Restorable intraoperative lung injury was observed in one case and no major vessel injuries were observed. The postoperative course was satisfactory with a 29.5-day median length of hospital stay (range, 16-60 days). The gastric tube inversion technique combined with the laparoscopic mediastinal approach for patients with retrosternal-reconstructed gastric tube cancer was shown to be safe and less invasive and should be considered in resection of the reconstructed gastric tube.

Laparoscopic mediastinal approach for retrosternal gastric conduit cancer after esophagectomy

The prognosis of esophageal cancer has improved, but the incidence of gastric conduit cancer has increased. Gastric conduit cancer is difficult to treat because current treatment options are highly invasive; in particular, surgical procedures have high mortality and modality. Treatment through the retrosternal route usually requires sternotomy, which often causes lethal osteomyelitis. To prevent lethal complications and reduce invasiveness, we used the laparoscopic mediastinal approach. Here, we report a successful case using the laparoscopic mediastinal approach for the treatment of gastric conduit cancer through the retrosternal route. Despite a few concerns, this approach can be a treatment option for gastric conduit cancer through the retrosternal route.

Distal gastric tube resection with vascular preservation for gastric tube cancer: A case report and review of literature

BACKGROUND

Survival rates in patients with esophageal cancer undergoing esophagectomy have improved, but the prevalence of gastric tube cancer (GTC) has also increased. Total resection of the gastric tube with lymph node dissection is considered a radical treatment, but GTC surgery is more invasive and involves a higher risk of severe complications or death, particularly in elderly patients.

CASE SUMMARY

We report an elderly patient with early GTC that had invaded the duodenum who was successfully treated with resection of the distal gastric tube and Roux-en-Y (R-Y) reconstruction. The tumor was a type 0-IIc lesion with ulcer scars surrounding the pyloric ring. Endoscopic submucosal resection was not indicated because the primary lesion was submucosally invasive, was undifferentiated type, surrounded the pyloric ring, and had invaded the duodenum. Resection of distal gastric tube with R-Y reconstruction was safely performed, with preservation of the right gastroepiploic artery (RGEA) and right gastric artery (RGA).

CONCLUSION

Distal resection of the gastric tube with preservation of the RGEA and RGA is a good treatment option for elderly patients with cT1bN0 GTC in the lower part of the gastric tube.

Thoracoscopic retrosternal gastric conduit resection in the supine position for gastric tube cancer

INTRODUCTION

Recent advances in the treatment for esophageal cancer have improved the prognosis after esophagectomy, but they have led to an increased incidence of gastric tube cancer. In most patients who underwent retrosternal reconstruction, median sternotomy is performed; it is associated with a risk of postoperative bleeding and osteomyelitis, and pain often negatively affects respiration. Here, we report the first case of thoracoscopic retrosternal gastric conduit resection in the supine position (TRGR-S).

MATERIALS AND SURGICAL TECHNIQUE

A 75-year-old male patient was placed in the supine position. Four ports were placed in the left chest wall. The gastric tube was separated from the epicardium, sternum, and left brachiocephalic vein. Because of adhesions between the gastric tube and the right pleura, combined resection of the right pleura was performed. The dorsal side of the gastric tube was dissected before the ventral side, enabling the gastric tube to be suspended from the back of the sternum and, thus, making it easier to expose the surgical field. Next, pedicled jejunal reconstruction via the presternal route was performed. There were no postoperative complications. The pathological diagnosis was signet ring cell carcinoma (pT1b, pN0, M0, pStage I), indicating R0 resection.

DISCUSSION

TRGR-S does not require sternotomy, reducing the risk of postoperative bleeding and osteomyelitis. In the presence of adhesions, TRGR-S is safe and provides a good surgical view. It is also reliable procedure for resection of retrosternal gastric tube cancer, and it is ergonomic for surgeons.

Case report: Gastric tube cancer after esophagectomy-Retrograde perfusion after proximal resection of right gastroepiploic artery

INTRODUCTION

We report a case of a 57-year-old patient with gastric tube cancer after subtotal esophagectomy and retrosternal gastric pull up.

CASE PRESENTATION

The patient developed gastric cancer 4 years after undergoing treatment for esophageal squamous cell cancer; the treatments included thoracoscopic subtotal esophagectomy, gastric pull-up reconstruction via a retrosternal route in salvage setting following definitive chemoradiation. Because the gastric tube cancer was located around the pylorus, transabdominal partial resection, which is much less invasive than total resection via sternotomy, was performed. During surgery, retrograde pulsation of the proximally resected right gastroepiploic artery was observed. Owing to an ample blood supply to the oral remnant of the gastric tube, vascular reconstruction of the right gastroepiploic artery was omitted. The postoperative recovery was eventless.

DISCUSSION

The right gastroepiploic artery is considered essential for blood supply to the gastric tube. However, there was no sign of ischemia after proximal resection of this artery, which suggests the vasculature was altered after gastric tube construction.

CONCLUSION

This case shows that partial distal resection of the gastric tube can be performed safely without vascular reconstruction of the right gastroepiploic artery. Favorable long-term results after gastric tube reconstruction support the possibility of bilateral blood supply to the gastroepiploic arcade.

Gastric tube resection due to metachronic cancer and a recurrence in anastomosis after Ivor-Lewis esophagectomy--case report

Gastric tube after esophagectomy can be the site of local recurrence or the development of second primary tumor which implies poor prognosis. The study presents an extremely rare case of a patient after Ivor-Lewis esophagectomy for squamous cell carcinoma, in whom there was detected local recurrence in the anastomosis associated with metachronous primary tumor in gastric tube. Esophageal reresection with the upper part of the stomach was performed. Left colonic segment supplied by middle colic vessels transposed through retrosternal route was used as new esophageal substitute.
