Transhiatal Chest Drainage Reduces The Frequency of Postoperative Thoracentesis In Transmediastinal Esophagectomy For Esophageal Cancer: A Retrospective Study

Background: Transmediastinal esophagectomy for esophageal cancer occasionally results in the postoperative accumulation of pleural effusion despite the preservation of the mediastinal pleura. Transhiatal chest drainage has reported utility in thoracic esophagectomy; however, its use in transmediastinal esophagectomy remains unelucidated. This study aimed to evaluate the effectiveness and safety of transhiatal chest drainage in transmediastinal esophagectomy.Methods: This retrospective study included patients who underwent transmediastinal esophagectomy for esophageal cancer from 2018 to 2020. The transhiatal chest drainage involved the insertion of a 19-Fr Blake® drain from the inferior hepatic space to the left thoracic cavity through the hiatus. The drainage group comprising 13 patients was compared with the non-drainage group comprising 13 patients in whom a transhiatal chest drainage tube was not placed during transmediastinal esophagectomy.Results: The frequency of thoracentesis in the drainage group was significantly lower than that in the non-drainage group (p = 0.03). There were no significant differences between the two groups in terms of the occurrence of other postoperative complications, duration of oxygen administration, and postoperative hospital stay.Conclusions: Transhiatal chest drainage could evacuate pleural effusion effectively and safely after transmediastinal esophagectomy. Therefore, this procedure is clinically useful in transmediastinal esophagectomy for esophageal cancer.

Surgical Treatment of Esophageal Advanced Achalasia

Of the several procedures that has to treat esophageal achalasia, the esophagectomy is to be the most indicated in advanced disease, which prompted Pinotti the disseminate the transmediastinal esophagectomy technique in the 1970s, with the advantage of avoiding thoracotomy. Nevertheless, several series demonstrated that this technique was not exempt from complications one of which could lead to massive hemopneumothorax due to injury to the trachea- bronchial tree and vessels due the periesophagitis that may be present with consequent adherence of the esophagus to these noble organs. Thus, Aquino in 1996 introduced the esophageal mucosectomy technique with preservation of the esophageal muscle tunic at the level of mediastinum as well as the transposition of the stomach to the cervical region inside in this tunic for the reconstruction of digestive tract. The advantage of this procedure is to avoid transgression of the mediastinum. This author describes in details this procedure, and shows early results and late evaluation using the ECKARDT score in a series of patients showing the advantages of the esophageal mucosectomy due the low incidence of immediate postoperative complications and good resolution in long term due the absence of symptoms in most patients.

145 ADVANTAGES OF MINIMALLY INVASIVE TRANSMEDIASTINAL ESOPHAGECTOMY IN ELDERLY PATIENTS WITH ESOPHAGEAL CANCER

Esophagectomy for esophageal cancer (EC) is one of the most invasive surgical procedures and, especially for elderly patients, postoperative respiratory complication (PRC) is still frequent and life-threatening. We started esophagectomy by a laparoscopic transhiatal approach in 2009, and single-port mediastinoscopic cervical approach in 2014. Nowadays, we have performed total mediastinal lymph node dissection without thoracic approach. The purpose of this study was to evaluate transmediastinal esophagectomy (TME) for the prevention of PRC in elderly patients. Methods 1) Patients with EC performed TME (n = 238) were compared with those performed the right thoracotomy (n = 185). 2) Outcomes of TME for elderly patients (75 years and older, n = 48) was evaluated by comparing with non-elderly patients (n = 190). 3) Elderly patients performed subtotal esophagectomy were divided into 2 groups according to the presence (n = 12) or absence (n = 51) of PRC. The two groups were compared about clinicopathological factors, and risk factors of PRC were analyzed. Results 1) Percentage of elderly patients was higher in TME group (20.2% vs 8.1%). The operative time and bleeding were decreased by TME. The number of resected LNs and pR0 rate were not different between two groups. In TME groups, the occurrence of PRC was significantly reduced (10.1% vs 28.1%). 2) 81.3% of elderly patients were able to extubation on 0POD, and there was no significant difference in PRC between two groups. 3) Univariate analysis showed that surgical approach was significantly different between two groups. Multivariate analysis showed that thoracotomy was the strongest risk factor of PRC for elderly patients. Conclusion This study showed that our surgical procedure was less invasive during operation and resulted in a safe en-bloc mediastinal lymph node dissection. For elderly patients, TME was the effective minimally invasive approach and was able to reduce the occurrence of PRC.

Comparison of short-term outcomes between transthoracic and robot-assisted transmediastinal radical surgery for esophageal cancer: a prospective study

Background The present study aimed to assess the lower invasiveness of robot-assisted transmediastinal radical esophagectomy by prospectively comparing this procedure with transthoracic esophagectomy in terms of perioperative outcomes, serum cytokine levels, and respiratory function after surgery for esophageal cancer. Methods Patients who underwent a robot-assisted transmediastinal esophagectomy or transthoracic esophagectomy between April 2015 and March 2017 were included. The perioperative outcomes, preoperative and postoperative serum IL-6, IL-8, and IL-10 levels, and respiratory function measured preoperatively and at 6 months postoperatively were compared in patients with a robot-assisted transmediastinal esophagectomy and those with a transthoracic esophagectomy. Results Sixty patients with esophageal cancer were enrolled. The transmediastinal esophagectomy group had a significantly lower incidence of postoperative pneumonia (p = 0.002) and a significantly shorter postoperative hospital stay (p < 0.0002). The serum IL-6 levels on postoperative days 1, 3, 5, and 7 were significantly lower in the transmediastinal esophagectomy group (p = 0.005, 0.0007, 0.022, 0.020, respectively). In the latter group, the serum IL-8 level was significantly lower immediately after surgery and on postoperative day 1 (p = 0.003, 0.001, respectively) while the serum IL-10 level was significantly lower immediately after surgery (p = 0.041). The reduction in vital capacity, percent vital capacity, forced vital capacity, and forced expiratory volume at 1.0 s 6 months after surgery was significantly greater in the transthoracic esophagectomy group (p < 0.0001 for all four measurements). Conclusions Although further, large-scale studies are needed to confirm our findings, robot-assisted transmediastinal esophagectomy may confer short-term benefits in radical surgery for esophageal cancer.

Long-term outcomes and safety of radical transmediastinal esophagectomy with preoperative docetaxel, cisplatin, and 5-fluorouracil combination chemotherapy for locally advanced squamous cell carcinoma of the thoracic esophagus

Background It is unknown whether transmediastinal esophagectomy (TME) is an acceptable surgical procedure for locally advanced esophageal squamous cell carcinoma (ESCC). Therefore, we investigated the feasibility of long-term survival after TME with neoadjuvant docetaxel, cisplatin, and 5-fluorouracil combination chemotherapy (DCF therapy). Methods This retrospective, observational study included locally advanced resectable ESCC. All patients received two cycles of preoperative DCF therapy (60 mg/m2 of docetaxel and cisplatin on day 1 and 700 mg/m2/day of 5-FU on days 1–5 in each cycle) followed by radical TME. The main outcomes were survival and the rate of adverse events of chemotherapy and surgery. Results Sixteen patients were included in this study. All patients received two cycles of DCF therapy, followed by surgery. The median follow-up duration of the 16 patients was 35.4 months. The 2-year overall survival (OS) was 93.3% (95% confidence interval [CI], 61.3–99.0), and the 3-year OS was 78.8% (95% CI, 47.3–92.7). The 2-year and 3-year relapse-free survivals were both 73.3% (95% CI, 43.6–89.1). Leukopenia and neutropenia occurred in most patients; however, they were controllable. Fifteen patients completed TME, and one was converted to open transthoracic esophagectomy because of tracheal injury. Three-field dissection was performed for 12 of 16 patients (75%), and R0 resection was achieved in 15 of 16 patients (93.8%). Three cases of grade IIIb chylothorax were observed. There was no mortality in this study. Conclusion Combined neoadjuvant DCF and TME for locally advanced ESCC was safe and less invasive than traditional therapies and had a satisfactory long-term prognosis.

Evaluation of urgent esophagectomy in esophageal perforation

BACKGROUND: Esophageal trauma is considered one of the most severe lesions of the digestive tract. There is still much controversy in choosing the best treatment for cases of esophageal perforation since that decision involves many variables. The readiness of medical care, the patient's clinical status, the local conditions of the perforated segment, and the severity of the associated injuries must be considered for the most adequate therapeutic choice. AIM: To demonstrate and to analyze the results of urgent esophagectomy in a series of patients with esophageal perforation. METHODS: A retrospective study of 31 patients with confirmed esophageal perforation. Most injuries were due to endoscopic dilatation of benign esophageal disorders, which had evolved with stenosis. The diagnosis of perforation was based on clinical parameters, laboratory tests, and endoscopic images. The main surgical technique used was transmediastinal esophagectomy followed by reconstruction of the digestive tract in a second surgical procedure. Patients were evaluated for the development of systemic and local complications, especially for the dehiscence or stricture of the anastomosis of the cervical esophagus with either the stomach or the transposed colon. RESULTS: Early postoperative evaluation showed a survival rate of 77.1% in relation to the proposed surgery, and 45% of these patients presented no further complications. The other patients had one or more complications, being pulmonary infection and anastomotic fistula the most frequent. The seven patients (22.9%) who underwent esophageal resection 48 hours after the diagnosis died of sepsis. At medium and long-term assessments, most patients reported a good quality of life and full satisfaction regarding the surgery outcomes. CONCLUSIONS: Despite the morbidity, emergency esophagectomy has its validity, especially in well indicated cases of esophageal perforation subsequent to endoscopic dilation for benign strictures.
