Gastric-tube versus whole-stomach esophagectomy for esophageal cancer: A systematic review and meta-analysis. PLoS One. 2017;12:e0173416. [PMID: 28267808 PMCID: PMC5340360 DOI: 10.1371/journal.pone.0173416]

Laparoscopic and thoracoscopic whole-stomach esophagectomy with preoperative pyloric balloon dilatation for esophageal cancer: a prospective multicenter case-series outcome

INTRODUCTION

To mitigate gastroparesis as well as other post-operative complications, we undertook a prospective multicenter study to assess the feasibility, safety, and efficacy in the short-term outcomes of laparoscopic and thoracoscopic whole stomach esophagectomy with preoperative pyloric balloon dilatation.

METHODS

A prospective descriptive study on 37 patients with laparoscopic and thoracoscopic whole stomach esophagectomy with preoperative pyloric balloon dilatation from January 2019 to March 2023. The perioperative indications, clinical data, intra-operative index, pathological postoperative specimens, postoperative complications, and follow-up results were retrospectively evaluated.

RESULTS

In our study, all patients were male, with dysphagia as the predominant symptom (45.9%). Esophageal cancer incidence was similar between middle and lower thirds. Nodules were the primary finding on esophagoscopy (48.6%). Preoperative pyloric dilation averaged 31.2 min without complications. Surgical duration ranged from 225 to 400 min (mean 305). Gastric tube fluid volume averaged 148.9 ± 110.66 ml per day. Among 34 post-operative cases underwent gastric transit scans, most had non-dilated stomachs with efficient pyloric drug circulation. Three cases required prolonged ventilation, precluding pyloric circulation scans. Four patients developed chylous fistula, one requiring chest tube embolization. Recurrent laryngeal nerve damage occurred in 10.8% of cases.

CONCLUSION

After evaluating esophageal cancer patients undergoing laparoscopic whole-stomach esophagectomy with preoperative pyloric balloon dilatation, it was found that this procedure is safe, effective, and significantly reduces postoperative gastroparesis and related complications.

Minimally Invasive Ivor Lewis Esophagectomy

Minimally invasive Ivor Lewis esophagectomy is a technically demanding operation that requires an experienced surgeon, assistant, and anesthesiologist. The preoperative workup should focus on the extent of disease and extent of resection required, as well as the cardiopulmonary fitness of the patient. Surgical outcomes show decreased postoperative pain, decreased morbidity largely due to a reduction in respiratory complications, and decreased length of stay. Quality metrics and 5-year overall survival are equivalent to traditional open esophagectomy.

Advances in the Surgical Management of Esophageal Cancer

Radical esophagectomy with two or three-field lymphadenectomy remains the mainstay of curative treatment for localized esophageal cancer, often in combination with systemic chemotherapy and/or radiotherapy. In this article, we describe notable advances in the surgical management of esophageal cancer over the past decade that have led to an improvement in both surgical and oncologic outcomes. In addition, we discuss new approaches to surgical management currently under investigation that have the potential to offer further benefits to appropriately selected patients. These incremental breakthroughs primarily include advances in endoscopic and minimally invasive techniques, perioperative management protocols, as well as the application of local therapies, including surgery, to oligometastatic disease.

Dietary habits and nutrition status in esophageal cancer patients after esophageal reconstruction

Background

Surgery is the cornerstone of the treatment of esophageal cancer (EC). This study is to evaluate the dietary habits and nutrition status in EC patients who underwent esophagectomy followed by esophageal reconstruction.

Methods

This retrospective study included patients with EC who underwent esophagectomy followed by esophageal reconstruction in the Department of Thoracic Surgery I of Peking University Cancer Hospital between February 2014 and December 2018. The primary outcomes were dietary habits and nutrition status. The secondary outcomes were gastrointestinal symptoms and quality of life (QoL).

Results

A total of 346 patients were included. At 30 months after the operation, 90.2% of the patients had recovered to regular dietary habits, 72.8% of patients had a restored frequency of preoperative regular food intake, 2.3% of the patients ate more than six times a day, and 0.6% had semi-liquid food because of bad teeth. The nutrition status remained stable after 6 months postoperatively and recovered slightly 1 year after the surgery. At 30 months after the operation, the most common gastrointestinal symptoms were reflux (38.4%), dysphagia (15.3%), hoarseness (11.8%), abdominal distension (6.6%), diarrhea (2.9%), and nausea and vomiting (2.3%). According to the European Organization for Research and Treatment of Cancer, Quality of Life Questionnaire-OG 25 (EORTC QLQ-OG 25), the factors that affected the life quality of patients during follow-up were anxiety, reflux, and dietary limitations.

Conclusions

Most patients with EC who underwent esophageal reconstruction recovered to regular dietary habits and stable nutrition status, while some may still suffer from gastrointestinal symptoms, anxiety, and dietary limitations.

Comparison of the subtotal and narrow gastric conduit for cervical esophagogastrostomy after esophagectomy in esophageal cancer patients: a propensity score-matched analysis

BACKGROUND

Several reports have compared narrow gastric conduit (NGC) with subtotal gastric conduit (SGC) for cervical esophagogastrostomy after esophagectomy; however, whether which one is more beneficial in terms of postoperative complications remains unclear. To determine the optimal gastric conduit type, we retrospectively investigated and compared the postoperative complications between NGC and SGC used in cervical circular-tapered esophagogastrostomy after esophagectomy through a propensity score-matched analysis.

METHODS

Between 2008 and 2022, 577 consecutive esophageal cancer patients who underwent esophagectomy and cervical circular-stapled esophagogastrostomy were enrolled in this study.

RESULTS

Of the 577 patients, 77 were included each in the SGC and NGC groups, after propensity score matching. Clinical characteristics did not differ between the two groups. The anastomotic leakage rate was significantly lower in the SGC group than in the NGC group (5% vs. 22%, p < 0.01). The anastomotic stenosis rate was significantly higher in the SGC group (16% vs. 5%, p = 0.03). Multivariate logistic analysis showed that NGC, subcutaneous route, and age were significant independent factors associated with anastomotic leakage (odds ratios, 8.58, 6.49, and 5.21; p < 0.01, < 0.01 and 0.03, respectively) and that SGC was a significant independent factor associated with anastomotic stricture (odds ratios, 4.91; p = 0.04).

CONCLUSIONS

In cervical circular-stapled esophagogastrostomy after esophagectomy, SGC was superior to NGC in terms of reducing the risk of anastomotic leakage, although the risk of anastomotic stricture needs to be resolved.

Comparison of wide and narrow gastric conduit in esophageal cancer surgery

BACKGROUND

Gastric conduit is most widely used method for esophageal reconstruction. Despite its popularity, certain complications, such as anastomotic leakage and strictures, remain to be resolved. In the present study, we reviewed the outcomes of narrow gastric conduit compared to wide gastric conduit reconstruction.

METHODS

We retrospectively reviewed 493 patients with esophageal cancer who received esophagectomy with reconstruction in Taichung Veteran General Hospital, Taiwan between January 2010 and December 2019. We performed gastric conduit reconstruction with two different methods, narrow gastric conduit made of multistaples (more than four staples) and wide gastric conduit made of two or three staples. Among the 493 patients, 170 patients underwent wide gastric conduit formation and 323 patients underwent narrow gastric conduit. After propensity score matching, 140 patients from each group were matched by 1:1.

RESULTS

The average anastomotic leakage rate is 80 of 493 (16.23%). The leakage rate, length of hospital stay, intensive care unit (ICU) admission, and ICU stay were significantly lower in the narrow gastric conduit group than in the wide gastric conduit group. The need for postoperation dilatation was significantly higher in wide gastric conduit group (19.41% vs 11.76%, p = 0.0217), and the time to first dilatation was similar in both groups ( p = 0.9808). Similar results were observed even after propensity score matching. In univariate analysis, the narrow gastric conduit, circular stapler, video-assisted thoracic surgery, and laparoscopic surgery were associated with a reduced risk of anastomotic leakage. However, these factors are not statistically significant in a multivariate logistic regression analysis.

CONCLUSION

The narrow gastric conduit is not inferior to the wide gastric conduit and can be considered an alternative option for gastric conduit preparation.

Postoperative Outcomes and Quality of Life After Left Thoracoabdominal Esophagogastrectomy: Contrasting Esophagogastrostomy with Esophagojejunostomy

BACKGROUND

Following left thoracoabdominal (LTA) esophagogastrectomy, gastrointestinal continuity can be re-established via esophagogastrostomy or esophagojejunostomy. We explored how the method of reconstruction impacted postoperative outcomes and quality of life (QoL).

METHODS

From January 2007 to January 2022, patients undergoing LTA were identified from a single center's prospectively maintained database. Following esophagogastrectomy or extended total gastrectomy, an esophagogastrostomy (GAS) or Roux-en-Y esophagojejunostomy (R-Y) was fashioned. Postoperative outcomes were compared according to the method of reconstruction. The Functional Assessment of Cancer Therapy-Esophagus (FACT-E) questionnaire compared QoL.

RESULTS

Of the 147 LTA patients identified, 135 (92%) were included-97 GAS (72%) and 38 R-Y patients (28%). R-Y patients had more ypT3/4 lesions (97% vs. 61%, p ≤ 0.001) and a similar incidence of ypN+/M+ disease. Anastomotic leaks were more common among GAS patients (17% vs. 3%, p = 0.023), however grade 3/4 complications (26.6% vs. 19.4%, p = 0.498), reoperation, intensive care admission, hospital representation and readmission were similar. FACT-E data were available for 68/97 (70%) GAS patients and 22/38 (58%) R-Y patients, with scores for 80/21/24/18/23/24 patients at baseline/preoperatively/1 month/3-6 months/1-3 years/3+ years postoperatively, respectively. Comparing between the groups, the scores were similar at each timepoint. FACT-E improved between baseline and preoperatively (79, 34-124 vs. 102, 81-123, p = 0.027). Only at 3+ years were postoperative scores equivalent to preoperative values. GAS patients had more reflux and esophagitis >6 months postoperatively (54% vs. 13%, p = 0.048; 62% vs. 0%, p ≤ 0.001).

CONCLUSION

While the type of reconstruction did not affect QoL, it did affect the postoperative course.

Combined endoscopic stenting and laparoscopic stent fixation for benign gastric tube stricture after esophagectomy: a case report

BACKGROUND

There are several options for the treatment of gastrointestinal stricture, including endoscopic stent placement and bypass surgery. However, a benign stricture is difficult to manage in a reconstructed gastric tube in the thoracic cavity owing to the technical difficulty of bypass surgery, and the possibility of stent migration.

CASE PRESENTATION

A 78-year-old woman was admitted to our hospital for treatment for her inability to eat. She had undergone video-assisted subtotal esophagectomy with retromediastinal gastric tube reconstruction 7 years earlier. At the current admission, there was a severely dilated gastric tube in the thoracic cavity with a soft stricture immediately anterior to the spine. Conservative therapy was ineffective; therefore, endoscopic stenting was performed. However, the stent migrated to the upper side of the stricture because the stricture was mild, and the stent was not fixed in the gastric tube. Next, endoscopic stent placement followed by laparoscopic stent fixation was performed. The stent was patent and worked well, and the patient's body weight increased. However, the stent collapsed 2 years later, with recurrence of symptoms. Stent-in-stent placement with an over-the-scope clip was performed, and the second stent was also patent and worked well.

CONCLUSIONS

Laparoscopic stent fixation with endoscopic stent placement could be an effective option for patients with a benign stricture in the reconstructed gastric tube.

A case of Barrett's esophageal adenocarcinoma and severe scoliosis with successful salvage esophagectomy after definitive chemoradiotherapy

BACKGROUND

Severe scoliosis can cause reflux esophagitis, and is a risk factor for Barrett's adenocarcinoma of the esophagus. Severe scoliosis is associated with respiratory dysfunction, impaired operative tolerance, and anatomical difficulty in surgical manipulation, and is, therefore, considered a high surgical risk. In this report, we describe the case of a young patient with Barrett's esophageal adenocarcinoma with severe scoliosis who underwent salvage surgery after radical chemoradiotherapy.

CASE PRESENTATION

The patient was a 39-year-old male. Although he had severe scoliosis and paraplegia of both lower limbs since childhood, he was independent in activities of daily living. His previous doctor, who diagnosed the esophageal cancer, determined that surgery was not indicated due to the coexistence of severe scoliosis, so he underwent chemoradiotherapy with curative intent. After chemoradiotherapy, the patient was referred to our hospital for a second opinion because of a tumor remnant. After various additional examinations, thoracoscopic and laparoscopic subtotal esophagectomy for esophageal cancer was performed, along with ante-thoracic route reconstruction using a narrow gastric tube. Although the patient had symptoms associated with postoperative reflux, he recovered well overall and was discharged home about 4 weeks after surgery.

CONCLUSIONS

We report the case of an esophageal cancer patient with severe scoliosis at high surgical risk who underwent successful minimally invasive esophagectomy.

Different gastric tubes in esophageal reconstruction during esophagectomy

Esophagectomy is currently the mainstay of treatment for resectable esophageal carcinoma. Gastric grafts are the first substitutes in esophageal reconstruction. According to the different tailoring methods applied to the stomach, gastric grafts can be classified as whole stomach, subtotal stomach and gastric tube. Gastric-tube placement has been proven to be the preferred method, with advantages in terms of postoperative complications and long-term survival. In recent years, several novel methods involving special-shaped gastric tubes have been proposed, which have further decreased the incidence of perioperative complications. This article will review the progress and clinical application status of different types of gastric grafts from the perspectives of preparation methods, studies of anatomy and perioperative outcomes, existing problems and future outlook.

What is the best reconstruction procedure after esophagectomy? A meta-analysis comparing posterior mediastinal and retrosternal approaches

Thoracic esophagectomy is a particularly invasive and complicated surgical procedure, with a reconstruction of the gastrointestinal tract, such as the stomach, jejunum, or colon. The posterior mediastinal, retrosternal, and subcutaneous routes are the three possible esophageal reconstruction routes. Each route has advantages and disadvantages, and the optimal reconstruction route after esophagectomy remains controversial. Additionally, the best anastomotic techniques after esophagectomy in terms of location (Ivor Lewis or McKeown) and suturing (manual or mechanical) are debatable. Our meta-analysis investigating postoperative complications after esophagectomy between the posterior mediastinal and retrosternal routes revealed that the posterior mediastinal route was associated with a significantly lower anastomotic leakage rate than the retrosternal route (odds ratio = 0.78, 95% confidence interval: 0.70-0.87, p < 0.0001). Conversely, pulmonary complications (odds ratio = 0.80, 95% confidence interval: 0.58-1.11, p = 0.19) and mortality between the posterior mediastinal and retrosternal routes (odds ratio = 0.79, 95% confidence interval: 0.56-1.12, p = 0.19) were not significantly different. However, the incidence of pneumonia may be lower when using the retrosternal route rather than the posterior mediastinal route for performing minimally invasive esophagectomy. The McKeown procedure is oncologically necessary for tumors located above the carina to dissect upper mediastinal and cervical lymph nodes; however, the Ivor Lewis procedure offers perioperative and oncological safety for tumors located under the carina. An individualized treatment strategy for selecting the optimal reconstruction procedure can be proposed in future studies based on oncological and patient risk factors considering mid- to long-term quality of life.

Wider Gastric Conduit Morphology Is Associated with Improved Blood Flow During Esophagectomy

BACKGROUND

It remains unclear what is the ideal conduit shape. The aim of this study was to evaluate association between specific gastric conduit morphology, considering width and length, with its perfusion and the incidence of anastomotic leaks after esophagectomy.

METHODS

Patients who underwent an esophagectomy with cervical esophagogastric anastomosis between 2015 and 2021 were evaluated. Indocyanine green angiography was performed to evaluate gastric conduit perfusion, and ingress index (arterial inflow) and ingress time (venous outflow) were measured. The conduit width at the middle of the conduit and the short gastric length as the length from the last gastroepiploic branch to the perfusion assessment point were measured. Propensity score matching was performed to compare wide conduits with narrow conduits. Narrow and wide conduits were defined as < 4 and ≥ 5 cm, respectively.

RESULTS

Three hundred fifty-eight patients were reviewed. After applying matching, the wide conduits had higher ingress index (48.2 vs 33.3%, p < 0.001) and shorter ingress time (51.2 vs 66.3 s, p = 0.004) compared to the narrow conduits. Including the short gastric length in analysis, creating a wide conduit is a significant factor for better ingress index (p = 0.001), especially when the perfusion assessment point is 5 cm or farther from the last gastroepiploic branch. Anastomotic leaks did not differ between the groups.

CONCLUSIONS

Conduit width is a significant factor of gastric conduit perfusion, especially when the estimated anastomotic site was > 5 cm from the last gastroepiploic branch. Wide conduits seem to have better perfusion and creating a wider conduit might reduce anastomotic leaks.

The influence of anastomotic techniques on postoperative anastomotic complications: Results of the Oesophago-Gastric Anastomosis Audit

BACKGROUND

The optimal anastomotic techniques in esophagectomy to minimize rates of anastomotic leakage and conduit necrosis are not known. The aim of this study was to assess whether the anastomotic technique was associated with anastomotic failure after esophagectomy in the international Oesophago-Gastric Anastomosis Audit cohort.

METHODS

This prospective observational multicenter cohort study included patients undergoing esophagectomy for esophageal cancer over 9 months during 2018. The primary exposure was the anastomotic technique, classified as handsewn, linear stapled, or circular stapled. The primary outcome was anastomotic failure, namely a composite of anastomotic leakage and conduit necrosis, as defined by the Esophageal Complications Consensus Group. Multivariable logistic regression modeling was used to identify the association between anastomotic techniques and anastomotic failure, after adjustment for confounders.

RESULTS

Of the 2238 esophagectomies, the anastomosis was handsewn in 27.1%, linear stapled in 21.0%, and circular stapled in 51.9%. Anastomotic techniques differed significantly by the anastomosis sites (P < .001), with the majority of neck anastomoses being handsewn (69.9%), whereas most chest anastomoses were stapled (66.3% circular stapled and 19.3% linear stapled). Rates of anastomotic failure differed significantly among the anastomotic techniques (P < .001), from 19.3% in handsewn anastomoses, to 14.0% in linear stapled anastomoses, and 12.1% in circular stapled anastomoses. This effect remained significant after adjustment for confounding factors on multivariable analysis, with an odds ratio of 0.63 (95% CI, 0.46-0.86; P = .004) for circular stapled versus handsewn anastomosis. However, subgroup analysis by anastomosis site suggested that this effect was predominantly present in neck anastomoses, with anastomotic failure rates of 23.2% versus 14.6% versus 5.9% for handsewn versus linear stapled anastomoses versus circular stapled neck anastomoses, compared with 13.7% versus 13.8% versus 12.2% for chest anastomoses.

CONCLUSIONS

Handsewn anastomoses appear to be independently associated with higher rates of anastomotic failure compared with stapled anastomoses. However, this effect seems to be largely confined to neck anastomoses, with minimal differences between techniques observed for chest anastomoses. Further research into standardization of anastomotic approach and techniques may further improve outcomes.

Endoscopic Submucosal Dissection for Gastric Tube Carcinoma after Esophagectomy Contributes to Long-Term Outcomes

The incidence of gastric tube carcinoma (GTC) after esophagectomy for esophageal carcinoma has increased in recent years. Surgical removal of the reconstructed gastric tube is associated with high mortality, and endoscopic submucosal dissection (ESD) is a promising alternative. There are limited reports of ESD for GTC. This study investigated the efficacy and safety of ESD in GTC. This single-center retrospective study examined patients who underwent ESD for GTC after esophagectomy at our institution between 2003 and 2018. The curability of GTC with ESD was evaluated histologically according to the Japanese Gastric Cancer Treatment Guidelines. Patient characteristics and procedural and long-term outcomes were analyzed. Overall, 31 patients (29 men and 2 women; median age, 73 years) with 45 GTC lesions underwent ESD. The mean period between primary esophagectomy and the diagnosis of GTC was 10.6 years. Bleeding during ESD was noted in two patients (6.5%). No other adverse or fatal events such as perforation were noted. Complete resection and curative resection were documented in 80.6% and 48.4% of cases, respectively. The 3-year and 5-year overall survival rates were 67.6% and 47.7%, respectively. The 3-year and 5-year disease-specific survival rates were 100% and 92.9%, respectively. One patient died of GTC, and fourteen patients died of other diseases, including primary carcinoma in five cases. ESD was safe and provided good long-term outcomes in patients with GTC. Regular long-term gastroscopy is required for the early detection of GTC. Patients with GTC after esophagectomy for esophageal carcinoma have a high risk of other primary carcinomas or comorbidities after ESD.

Staple Line Dehiscence in Gastric Conduit Following Esophagectomy: A Complication Conspicuously Missing a Mention It Deserves

Following esophagectomy, anatomical reconstruction with a gastric tube is the most common practice. The construction of the gastric tube is done with staplers nowadays, be it a minimally invasive esophagectomy or a conventional open surgery. Even though anastomotic leak and conduit necrosis are reported widely in the literature, the number of studies on staple line dehiscence is meager in comparison. Management of conduit failure usually sacrifices conduit combined with a diverting cervical esophagostomy. We report a case of successful surgical management of a big staple line dehiscence and ‘salvaging of the conduit'.

Knockdown long non-coding RNA HCP5 enhances the radiosensitivity of esophageal carcinoma by modulating AKT signaling activation

Recently, long noncoding RNAs (lncRNAs) have been revealed to participate in cancer therapy. Especial in tumor radiotherapy, lncRNAs usually could enhance or restrict the radiosensitivity in different ways. LncRNA HCP5 is highly expressed in esophageal cancer and influenced the malignant behaviors of esophageal cancer cells. However, this study dedicates to clarify if lncRNA HCP5 affects the radiosensitivity of esophageal carcinoma. The expression levels of HCP5 in esophageal cancer and adjacent noncancerous tissue were first analyzed on the TCGA database and then detected by qRT-PCR. The related functional experiments were used to investigate whether the radiosensitivity of esophageal squamous cell carcinoma was affected by the inhibition of HCP5. The expression results showed HCP5 is upregulated in esophageal cancers compared to the normal tissues. Meanwhile, knockdown HCP5 further suppressed the proliferation and promoted the apoptosis of esophageal cancer cells treated with a 2 Gy dose of radiotherapy. Moreover, we uncovered that knockdown HCP5 eliminated radiotherapy resistance by modulating the miR-216a-3p/PDK1 axis to inhibit the AKT activation. Finally, rescue experiments pointed that lowering the miR-216a-3p expression weakened the inhibition effect of knockdown HCP5 on cells treated with radiotherapy. To summary, our results indicate that HCP5 is involved in esophageal carcinoma radiotherapy and knockdown HCP5 enhances the radiosensitivity of esophageal carcinoma by modulating AKT signaling activation.

Application of mediastinal drainage tube in intrathoracic esophageal anastomotic leakage for early diagnosis and effective treatment: a retrospective study

Background

Intrathoracic esophageal anastomotic leakage (AL) is one of the most fatal complications after esophagectomy. In this study, we placed an additional drainage tube in the esophagus bed and evaluated its effect in early diagnosis and treatment of AL.

Methods

From January 2010 to August 2020, 312 patients with esophageal or cardia carcinoma underwent esophageal resection with intrathoracic esophagogastric anastomosis. A total of 138 patients with only one pleural drainage tube were divided into the “Control Group” and 174 patients with a pleural drainage tube and an additional mediastinal drainage tube (MDT) were divided into the “Tube Group”. For all patients, the incidence of postoperative AL, the time to diagnosis, time to recovery, and patient outcome were analyzed.

Results

No significant differences were observed in the AL rate (P = 0.837) and postoperative pain between two groups. However, in the Tube Group, almost all the patients were diagnosed prior to the appearance of hyperpyrexia, which was considered as the earliest and most common symptom after AL. In the Tube Group, a significant decrease was observed in the incidence of incurable fistula, which required re-operation or variable treatments under gastroscopy when compared to the Control Group (P = 0.032). Finally, patients in the Tube Group showed reduced post AL hospital day (P = 0.015) and a lower mortality, however, when compared to the Control Group, no significant differences were observed (P = 0.188).

Conclusions

Placement of an MDT does not prevent AL, but it is an effective approach for earlier diagnosis of AL and facilitates fistula healing and patient recovery.

The assessment of intraoperative technique-related risk factors and the treatment of anastomotic leakage after esophagectomy: a narrative review

Anastomotic leakage, including cervical anastomotic leakage and intrathoracic anastomotic leakage, is a serious complication of esophageal cancer and a leading cause of death after esophagectomy. In fact, anastomotic leakage after esophagectomy can be caused by numerous factors in the preoperative, intraoperative, and postoperative periods. Intraoperative technique-related risk factors, including surgical methods, anastomosis sites, anastomosis methods, the type of gastric tube, and reconstruction routes, are the key causes of its occurrence. Anastomotic leakage treatments include both surgical and non-surgical treatments, while surgical treatment has high risks, many complications, and high mortality. Actually, non-surgical methods including naso-leakage drainage, stent, negative pressure therapy, and so on, are also very critical in the treatment of anastomotic leakage. So, the selection of correct and appropriate treatment methods plays an important role in alleviating the suffering of patients, shortening hospitalization time, and reducing mortality. This study undertook a systematic review in which data in the PubMed database were searched and analyzed to assess the safety and efficacy of surgical technique-related factors in esophagectomy, and appropriate treatment of anastomotic leakage after esophagectomy. In conclusion, gastric tube, posterior mediastinal route and stapled anastomosis are safe among esophagectomy surgical techniques, and non-surgical treatment of anastomotic leakage such as naso-leakage drainage is feasible in the majority of cases.

Aspiration pneumonia during general anesthesia induction after esophagectomy: A case report

BACKGROUND

Esophageal cancer is a common malignant tumor of the digestive system. At present, surgery is the most important treatment strategy. After esophagectomy and gastric esophagoplasty, the patients are prone to regurgitation. However, these patients currently do not receive much attention, especially from anesthesiologists.

CASE SUMMARY

A 55-year-old woman was scheduled for right lower lung lobectomy. The patient had undergone radical surgery for esophageal cancer under general anesthesia 6 mo prior. Although the patient had fasted for > 17 h, unexpected aspiration still occurred during induction of general anesthesia. Throughout the operation, oxygen saturation was 98%-100%, but the airway pressure was high (35 cmH₂O at double lung ventilation). The patient was sent to the intensive care unit after surgery. Bedside chest radiography was performed, which showed exudative lesions in both lungs compared with the preoperative image. After surgery, antibiotics were given to prevent lung infection. On day 2 in the intensive care unit, the patient was extubated and discharged on postoperative day 7 without complications related to aspiration pneumonia.

CONCLUSION

After esophagectomy, patients are prone to regurgitation. We recommend nasogastric tube placement followed by rapid sequence induction or conscious intubation.

Delayed Gastric Emptying after Esophagectomy: Management and Prevention

The quality of life associated with eating is becoming an increasingly significant problem for patients who undergo esophagectomy as a result of the improved survival rate after esophageal cancer surgery. Delayed gastric emptying (DGE) is a common complication after esophagectomy. Although several strategies have been proposed for the management and prevention of DGE, no clear consensus exists. The purpose of this review is to present a brief overview of DGE and to help clinicians choose the most appropriate treatment through an analysis of DGE by cause. Furthermore, we would like to suggest some tips to prevent DGE based on our experience.

Reflux Following Esophagectomy for Esophageal Cancer

Gastroesophageal reflux is a common problem after gastroesophageal resection and reconstruction, despite the routine prescription of proton pump inhibitors (PPIs). Resection of the lower esophageal sphincter and excision of the vagus nerve are generally thought to be the main factors that interfere with gastric motor function. However, physiological studies of reflux symptoms after esophagectomy are still lacking. Gastroesophageal reflux occurs frequently after esophagectomy, but there is no known effective method to prevent it. Therefore, in order to manage gastroesophageal reflux after esophagectomy, strict lifestyle modifications and gastric acid suppression treatment such as PPIs are needed, and further clinical studies are required.

Strategies to prevent anastomotic leakage after esophagectomy and gastric conduit reconstruction

Background

Surgery remains the cornerstone of esophageal cancer treatment but is burdened with high procedure-related morbidity. Anastomotic leakage as the most important surgical complication after esophagectomy is a key indicator for quality in surgical outcome research.

Purpose

The aim of this narrative review is to assess and summarize the current knowledge on prevention of anastomotic leakage after esophagectomy and to provide orientation for the reader in this challenging field of surgery.

Conclusions

There are various strategies to reduce postoperative morbidity and to prevent anastomotic leakage after esophagectomy, including adequate patient selection and preparation, and many technical-surgical and anesthesiological details. The scientific evidence regarding those strategies is highly heterogeneous, ranging from expert’s recommendations to randomized controlled trials. This review is intended to serve as an empirical guideline to improve the clinical management of patients undergoing esophagectomy with a special focus on anastomotic leakage prevention.

Thoracic stomach syndrome after whole-stomach esophagectomy for esophageal cancer mimicking tension pneumothorax: a case report

BACKGROUND

Sudden onset of respiratory failure is one of the most fearful manifestations in intensive care units. Among the differential diagnoses of respiratory failure, tension pneumothorax is a life-threatening disease that requires immediate invasive intervention to drain the air from the thoracic cavity. However, other etiologies with manifestations similar to those of tension pneumothorax should also be considered after whole-stomach esophagectomy for esophageal cancer. We report a rare case of a patient with thoracic stomach syndrome mimicking tension pneumothorax after esophagectomy with whole-stomach reconstruction.

CASE PRESENTATION

A 49-year-old Asian woman was admitted to our intensive care unit after esophagectomy for esophageal cancer with whole-stomach reconstruction while under sedation and intubated. Despite initial stable vital signs, the patient rapidly developed tachypnea, low blood pressure, and low oxygen saturation. Chest radiography revealed a mediastinal shift and led to a presumptive diagnosis of tension pneumothorax. Hence, an aspiration catheter was inserted into the right pleural space. However, her clinical symptoms did not improve. Chest computed tomography was performed, which revealed a significantly distended reconstructed stomach that was compressing the nearby lung parenchyma. Her respiration improved immediately after nasogastric tube placement. After the procedure, we successfully extubated the patient.

CONCLUSIONS

Similar to tension pneumothorax, thoracic stomach syndrome requires immediate drainage of air from the thoracic cavity. However, unlike tension pneumothorax, this condition requires nasogastric tube insertion, which is the only way to safely remove the accumulated air and avoid possible complications that could occur due to percutaneous drainage. For patient safety, it might be clinically important to place nasogastric tubes after esophagectomy with whole-stomach reconstruction, even if radiographic guidance is required. In addition, clinicians should consider thoracic stomach syndrome as one of the differential diagnoses of respiratory failure after whole-stomach esophagectomy.

Optimal mobilization of the stomach and the best place in the gastric tube for intrathoracic anastomosis

Esophagectomy with gastric tube reconstruction is a highly complex surgical procedure. With regard to mobilization of the stomach and optimal gastric tube preparation and anastomosis, there are several important intraoperative steps that can influence the outcome of the operation. This study aims to describe the optimal mobilization of the stomach for gastric tube reconstruction and explore the best place in the gastric tube for intrathoracic anastomosis after esophagectomy. A search of the literature was performed and results are described in a descriptive review. Based on literature and our own experience we describe important operating steps for laparoscopic stomach mobilisation for gastric tube reconstruction. Steps to create additional length include preserving the left gastroepiploic artery, transecting the right gastric artery, extended duodenal mobilization, and duodenal diversion with roux-Y reconstruction. Several techniques for intrathoracic anastomosis are described in literature. Several imaging techniques, of which fluorescence imaging is the most commonly used, are available to assess the vascularization of the gastric tube and to assist in determining the best place in the gastric tube for intra thoracic anastomosis. Although there is little evidence of exact technique on stomach mobilization and location for an intrathoracic anastomosis, many techniques are used by different authors with varying results.
