Laparoscopic and thoracoscopic esophagectomy with intrathoracic anastomosis for middle or lower esophageal carcinoma

Thoracoscopic mobilization of esophagus and laparoscopic mobilization of stomach with cervical anastomosis is employed widely in minimally invasive esophagectomy (MIE) for esophageal carcinoma. However, it is associated with high incidence of complications, including recurrent laryngeal nerve injury and anastomotic leak. This paper summarizes the key techniques in total laparoscopic and thoracoscopic esophagectomy with intrathoracic anastomosis for MIE in 62 patients of middle or lower esophageal cancer between March 2012 and August 2013. Total laparoscopic and thoracoscopic esophagectomy with intrathoracic anastomosis was performed to treat the middle or lower esophageal cancer. Laparoscopic and thoracoscopic Ivor-Lewis esophagectomy was performed using a circular stapler (Johnson and Johnson) intrathoracically to staple esophagogastric anastomosis and reconstruct the digestive tract. In addition, we performed tension-relieving anastomotic suture and embedded with pedicled omental flap. Compared with the trans-orally inserted anvil (OrVil) approach, the technique reported here is safe, feasible and user-friendly. Total thoracoscopic intrathoracic anastomosis can be performed with a circular stapler (Johnson and Johnson).     

Totally minimally invasive Ivor‐Lewis esophagectomy with single‐utility incision video‐assisted thoracoscopic surgery for treatment of mid‐lower esophageal cancer

The study aims to evaluate the safety and availability of totally minimally invasive Ivor‐Lewis esophagectomy (MIIE) with single‐utility incision video‐assisted thoracoscopic surgery. Forty‐one patients with mid‐lower thoracic esophageal cancer were prospectively treated with totally MIIE. Two stages of laparoscopic‐thoracoscopic procedures were performed. The first 29 patients were treated with four‐port video‐assisted thoracoscopic surgery (Group 1); the others were treated with single‐utility incision video‐assisted thoracoscopic surgery (Group 2). Short‐term clinicopathological outcomes were examined. All patients had negative tumor margins and were pathologically staged from T1N0M0 to T3N2M0. Among Group 1, there was one conversion to open surgery. The mean duration of surgery was 268.4 ± 37.8 minutes, and mean blood loss was 207.2 ± 74.1 mL without significant differences between groups. The average thoracic or abdominal lymph node yield was 12.6 ± 7.1 or 6 ± 5.8, respectively. The median postoperative hospital stay was 7 days. No mortalities occurred. Minor morbidity complicated by late‐stage gastroparesis occurred in two patients (4.9%) after discharge. Major morbidities, including intestinal obstruction and anastomotic leakage, occurred in three patients (7.3%) after discharge. Among Group 2, the average operative duration was 275.4 ± 31.2 minutes, and the mean blood loss was 220 ± 94.9 mL. One patient developed late‐stage anastomotic leakage. The average thoracic or abdominal lymph node yield was 14.7 ± 8.8 and 6.3 ± 5.7, respectively. No statistically significant differences were identified between Group 1 and Group 2. MIIE with single‐utility incision video‐assisted thoracoscopic surgery is feasible in patients with mid‐lower thoracic esophageal cancer without compromising the extent of surgical resection and perioperative outcomes.     

Optimal surgical approach for esophageal cancer in the era of minimally invasive esophagectomy and neoadjuvant therapy

The optimal surgical technique for the potentially curative treatment of patients with esophageal cancer is still under debate. The transhiatal esophagectomy (THE) with limited lymphadenectomy mainly focuses on a decrease of postoperative morbidity and mortality by preventing a formal thoracotomy. The transthoracic esophagectomy (TTE) with extended two‐field lymphadenectomy attempts to improve the radicality of the resection and thus to increase locoregional tumor control, but is associated with increased postoperative morbidity. The recent introduction of different minimally invasive techniques probably decreases postoperative morbidity following TTE, with reduction of especially pulmonary complications, but high‐quality evidence is still limited. It is widely agreed that extended lymphadenectomy as performed during TTE provides the benefit of more accurate staging, but its effect on improvement of survival is still debated. The literature on this topic is contradictory and the choice of surgical approach is primarily driven by personal opinions and institutional preferences. Moreover, the available evidence is mainly based on patients who underwent surgery alone without neoadjuvant therapy. Results of recent studies suggest that neoadjuvant chemoradiotherapy abolishes any possibly positive effect of extended lymphadenectomy as performed during TTE on survival, but this effect should be confirmed in future research. This review gives an overview and reflects the authors' personal view on the role of TTE and THE in the treatment of potentially curative treatment of patients with locally advanced esophageal cancer in the era of minimally invasive esophagectomy and neoadjuvant treatment and outlines future research perspectives.     

Patient reported outcomes (PROs) after minimally invasive and open esophagectomy

Esophagectomy for esophageal malignancies remains an operation with significant potential morbidity and mortality. However, surgical outcomes continue to improve over time and focus has shifted toward not just good outcomes, but quality of life post operatively. Patient reported outcomes (PROs) focus of quality of life measures via validated patient surveys has increasingly become a significant focus. While PROs do have their limitations, they represent a glimpse into the symptomatology, quality of life, and well-being of a patient undergoing a procedure with inherent morbidity. Working to improve outcomes from the perspective of the patient is not a new concept, but has becoming increasingly relevant as surgical quality for all procedures improves. The optimal approach to esophagectomy is controversial. Minimally invasive approaches attempt to avoid laparotomy and thoracotomy with the thought of improving post-operative quality of life by mitigating complications related to those open surgical approaches. The data in favor of laparoscopy and thoracoscopy is quite strong and multiple randomized controlled trials exist in this realm supporting minimally invasive approaches with regards to quality of life outcomes and more rapid return to patient’s preoperative baseline. The data in favor of a robotic approach for esophagectomy is not quite as robust, but more studies show that these approaches mirror the benefits of the laparoscopic and thoracoscopic approaches without robotic assistance.     

Radical minimally invasive esophagectomy for esophageal cancer via transcervical and transhiatal approaches: a narrative review

ObjectiveMinimally invasive esophagectomy (MIE) has been widely applied for the treatment of esophageal carcinoma. It is much less invasive, as it avoids employing a transthoracic procedure.BackgroundMIE via transcervical and transhiatal approaches has been adopted in our center. In this approach, with the assistance of single-port techniques or robotic-assisted surgical systems, the esophagus is mobilized under visualization, which is followed by the removal of esophageal and mediastinal lymph nodes.MethodsIncreasing the surgical space by mediastinal insufflation or by elevation of the sternum with a hook may improve intraoperative identification of tissues and facilitate intraoperative mobilizations. The procedure can be performed simultaneously via both cervical and abdominal approaches without the need for intraoperative turning of the patient, which shortens the operative time. Also, there is no need for thoracotomy or single-lung ventilation, which avoids disturbance to the respiratory and circulation systems.ConclusionsSuitable instruments, especially state-of-the-art energy instruments, facilitate surgical separation and hemostasis. This surgical procedure has become increasingly sophisticated over the past decade, and its modular operation has been widely recognized. The feasible place of the neck-esophageal hiatus rendezvous is on the left main bronchus around the subcarinal region. Here we describe the technical features, key steps, and necessary precautions of this minimally invasive surgery for esophageal carcinoma.     

Minimally invasive pharyngo-laryngo-esophagectomy: a salvage procedure for recurrent postcricoid esophageal cancer

Hypopharyngeal and cervical esophageal tumors represent 5-10% of all esophageal neoplasms and are challenging for both surgeons and oncologists, because the choice of the adequate therapeutic strategy is not clearly defined and therefore difficult. In fact, although surgical treatment represents the gold standard of therapy, chemo-radiotherapy, previously used as adjuvant treatment, has been more recently adopted with curative intent, leaving to surgery a salvage role only. When surgery is required it is advisable to reduce patients' trauma. The present study reports on a personal technique for minimally invasive pharyngo-laryngo-esophagectomy and reconstruction with the whole stomach. We use a laparoscopic approach for mobilization of the stomach, transhiatal esophageal dissection and to follow transhiatal gastric transposition to the neck combined to a cervicotomy to perform pharyngo-laryngectomy, proximal esophageal mobilization, and pharyngo-gastric anastomosis. We performed this technique on four patients with recurrent disease after initially curative primary chemo-radiotherapy. Mean operative time was 345 min (range: 300-384). There were no intraoperative complications. All patients were extubated immediately after the operation and were managed in postoperative care unit for a mean time of 10 days (range: 7-12). Enteral nutrition was begun on post-operative day (POD) 1. The nasogastric tube and drainages were removed on POD 11, and patients immediately started oral nutrition. One patient had a TIA (transient ischemic attack) on POD 2. All patients were discharged within 20 days (18-20). Initial experience with this minimally invasive technique in selected patients is encouraging because it seems to minimize postoperative complications and allows early rehabilitation.     

Minimally invasive esophagectomy learning curves with different types of background experience

BackgroundMinimally invasive esophagectomy (MIE) is a complex procedure with learning associated morbidity. The aim was to evaluate the learning curve for MIE focusing on short-term outcomes in two settings: (I) experienced MIE surgeon in new hospital (Hospital 1); (II) surgeons experienced with open esophagectomy and minimally invasive surrogate surgery (Hospital 2).MethodsIn Hospital 1 and Hospital 2, on intent-to-treat basis number of MIEs were 132 and 57, respectively. The primary outcomes were major complications and anastomosis leaks. Secondary outcomes were operative time, blood loss, lymph node yield, hospital stay and 1-year mortality. Length of learning curves were analyzed with risk-adjusted cumulative sum (RA-CUSUM) method.ResultsIn Hospital 1, major complication and anastomosis leak rates were 9.8% and 4.5%, 22.8% and 12.3% in Hospital 2, respectively. In Hospital 1, complication and leak rates remained stable. In Hospital 2, improvement occurred after 34 cases in major complications and 29 cases in leaks. Of secondary outcomes, improvements were seen in Hospital 1 in operative time after 61, blood loss after 86, lymph node yield after 52, hospital stay after 19 and 1-year mortality after 24 cases. In Hospital 2, improvement occurred in operative time after 30, blood loss after 15, lymph node yield after 45, hospital stay after 50 and 1-year mortality after 15 cases.ConclusionsAccording to this study, learning phase of the individual surgeon determines the outcomes of MIE, not the institutional learning phase.     

Development of less invasive surgical procedures for thoracic esophageal cancer

In order to minimize the invasiveness of the operative procedure for thoracic esophageal cancer, several procedures have been introduced since January 1997. They included: (i) perioperative use of steroids; (ii) muscle-sparing thoracotomy without costectomy; (iii) preparation of the gastric tube with preservation of sufficient blood supply; (iv) reconstruction of the alimentary tract via posterior-mediastinal route; and (v) formation of anastomosis between the remaining esophagus and the gastric tube at a location between the gastroepiploic arteries of the gastric greater curvature. Twenty-one patients who did not receive preoperative chemoradiotherapy underwent the newly developed procedure, and were compared with those receiving the original procedure. Hospital mortality was zero, and postoperative systemic inflammatory response syndrome was suppressed. The mean postoperative hospital stay was 21.5 days, and the actuarial 3-year survival rate was 76.2%. From the comparison with those receiving the original procedure, it can be concluded that the newly developed procedures were effective in minimizing surgical invasiveness and were sufficiently curative in terms of cancer treatment.

Thoracoscopic and laparoscopic radical esophagectomy with left neck anastomosis

We described a 50-year-old female, who came to our institute with the diagnosis of esophageal squamous cell carcinoma. The preoperative clinical diagnosis was stage II esophageal squamous cell carcinoma. The minimally invasive esophagectomy (MIE), combined thoracoscopic-laparoscopic esophagectomy with cervical anastomosis, was performed in this case. Total surgery time was 190 min and blood loss was 100 mL. Postoperative pathological exam suggested squamous cell carcinoma, without evidence of lymph node metastasis in any station (T2N0M0 IIb stage). The patient was discharged home on the 12^th postoperative day.     

Hybrid minimally invasive esophagectomy for cancer: impact on postoperative inflammatory and nutritional status

The purpose of this case–control study was to evaluate the impact of hybrid minimally invasive esophagectomy for cancer on surgical stress response and nutritional status. All 34 consecutive patients undergoing hybrid minimally invasive esophagectomy for cancer at our surgical unit between 2008 and 2013 were retrospectively compared with 34 patients undergoing esophagectomy with open gastric tubulization (open), matched for neoadjuvant therapy, pathological stage, gender and age. Demographic data, tumor features and postoperative course (including quality of life and systemic inflammatory and nutritional status) were compared. Postoperative course was similar in terms of complication rate. Length of stay in intensive care unit was shorter in patients undergoing hybrid minimally invasive esophagectomy (P = 0.002). In the first postoperative day, patients undergoing hybrid minimally invasive esophagectomy had lower C‐reactive protein levels (P = 0.001) and white cell blood count (P = 0.05), and higher albumin serum level (P = 0.001). In this group, albumin remained higher also at third (P = 0.06) and seventh (P = 0.008) postoperative day, and C‐reactive protein resulted lower at third post day (P = 0.04). Hybrid minimally invasive esophagectomy significantly improved the systemic inflammatory and catabolic response to surgical trauma, contributing to a shorter length of stay in intensive care unit.     

Application of a modified McKeown procedure (thoracoscopic esophageal mobilization three‐incision esophagectomy) in esophageal cancer surgery: Initial experience with 30 cases

Early efforts with minimally invasive esophagectomy (MIE) were hybrid approaches. No conclusive benefit was seen with this approach compared with the standard open procedure. Total MIE has demonstrated its advantages in single institution series. The drawbacks of total MIE include the steep learning curve and the high cost of the disposable instrumentation. We sought to determine the feasibility of modifying the surgical technique involved in the hybrid approach in an effort to decrease the cost of the surgery without compromising the outcome. From December 2007 to September 2008, the modified McKeown procedure (thoracoscopic esophageal mobilization three‐incision esophagectomy) was performed in 30 cases. The median operative time was 225 minutes (range, 195 ?290 minutes) and the median average time of VATS was 70 minutes (range, 50 ?130 minutes). Median lymph node retrieval was 25.6 ± 4.8 nodes (15.1 ± 3.4 intrathoracic) per patient. The median postoperative hospital stay was 17.1 ± 6.3 days. There was no in‐hospital (30 days) mortality. Postoperative complications occurred in 9 patients (30%), including 2 (6.7%) pneumonia, 1 (3.3%) chylothorax, 1 (3.3%) delayed gastric emptying ,1 (3.3%) vocal cord palsy, 2 (6.7%) neck anastomotic leaks, and 2 (6.7%) arrhythmias. This procedure is technically feasible and safe with lower mortality and mobility. The short‐term surgical outcomes are comparable with most of the total MIE reports. Performing the gastric mobilization and spontaneous neck anastomosis first greatly facilitate and simplifies the VATS maneuver.     

Effect of bilateral supraclavicular postoperative radiotherapy in middle and lower thoracic esophageal carcinoma

AIM: To evaluate whether postoperative radiotherapy is an alternative to neck lymph node surgery and if it provides a survival benefit for those receiving two-field, chest and abdomen, lymphadenectomy.METHODS: A total of 530 cases with middle and lower thoracic esophageal carcinoma in our hospital from January 2008 to April 2009 were selected and analyzed, of which 219 cases received right chest, upper abdominal incision Ivor-Lewis surgery and simultaneously underwent mediastinal and abdominal two-field lymphadenectomy. If regional lymph node metastasis occurred within the recurrent laryngeal nerve, the patients would receive bilateral supraclavicular radiotherapy (DT = 5000cGy) to be adopted at postoperative 4-5 wk (Group A) or cervical lymphadenectomy at postoperative 3-4 wk (Group B). If there were no regional lymph node metastases within the recurrent laryngeal nerve, the patients only underwent two-field, chest and abdomen, lymphadenectomy (Group C).RESULTS: In 219 cases who underwent two-field lymphadenectomy, 91 cases were diagnosed with regional lymph node metastasis within the recurrent laryngeal nerve. Of them, 48 cases received cervical radiotherapy, and 43 cases underwent staging lymphadenectomy; 128 patients were not given the follow-up treatment of cervical radiotherapy because there was no regional lymph node metastasis within the recurrent laryngeal nerve. Five-year survival rates in group A and B were 47% and 50%, respectively, with no statistical difference between them, and the rate in group C was 58%.CONCLUSION: For patients with middle and lower thoracic esophageal carcinoma combined with lymph node metastasis within the recurrent laryngeal nerve, cervical radiotherapy can be a substitute for surgery and provide benefit.     

A preliminary experience with minimally invasive Ivor Lewis esophagectomy

With several small series examining minimally invasive Ivor Lewis esophagectomies, we look to contribute to a growing experience. In reporting our initial results, safety, initial oncologic completeness, and preliminary outcomes with a minimally invasive Ivor Lewis esophagectomy were demonstrated. From 2007 to 2010, 40 minimally invasive Ivor Lewis esophagectomies were carried out. The approach was a laparoscopic mobilization of the stomach and a thoracoscopic esophageal mobilization and creation of a high intrathoracic anastomosis. Indications included esophageal cancer in 39 patients and esophageal gastrointestinal stromal tumor in one patient. Median age was 62 (range 39-77) with 31 (78%) male patients. Non-emergent conversion was required in two (5%) patients. Twenty-five (63%) patients underwent neoadjuvant therapy. Mean operative time was 364 minutes (range 285-455), and mean blood loss was 205 cc (range 100-400). All patients underwent an R0 resection including the removal of all Barrett's esophagus, and mean number of nodes harvested was 21 (range 11-41). Median intensive care unit stay was 1 day (range 1-3), and hospital stay was 7 days (range 6-19). There were no anastomotic leaks and no 30-day mortality. Postoperative complications included eight (21%) patients with atrial fibrillation and two (5%) chylothorax, one requiring ligation. At a mean follow-up of 16.5 months (range 1-39 months), five (13%) patients have had a distant recurrence; there have been no local recurrences. Minimally invasive Ivor Lewis esophagectomy, although technically challenging, can be carried out with reasonable operative times, a short length of stay, and minimal complication. Final oncologic validity is pending longer follow-up and a larger series.     

Short‐term outcomes of robotic radical esophagectomy for esophageal cancer by a nontransthoracic approach compared with conventional transthoracic surgery

Transthoracic esophagectomy (TTE) is believed to have advantages for mediastinal lymphadenectomy in the treatment of resectable esophageal cancer despite its association with a greater incidence of pulmonary complications and postoperative mortality. Transhiatal esophagectomy is regarded as less invasive, though insufficient in terms of lymph node dissection. With the aim of achieving lymph dissection equivalent to that of TTE, we have developed a nontransthoracic esophagectomy (NTTE) procedure combining a video‐assisted cervical approach for the upper mediastinum and a robot‐assisted transhiatal approach for the middle and lower mediastinum. We prospectively studied 22 accumulated cases of NTTE and verified feasibility by analyzing perioperative and histopathological outcomes. We compared this group's short‐term outcomes with outcomes of 139 equivalent esophageal cancer cases operated on at our institution by conventional TTE (TTE group). In the NTTE group, there were no procedure‐related events and no midway conversions to the conventional surgery; the mean operation time was longer (median, 524 vs. 428 minutes); estimated blood loss did not differ significantly between the two groups (median, 385 mL vs. 490 mL); in the NTTE group, the postoperative hospital stay was shorter (median, 18 days vs. 24 days). No postoperative pneumonia occurred in the NTTE group. The frequencies of other major postoperative complications did not differ significantly, nor were there differences in the numbers of harvested mediastinal lymph nodes (median, 30 vs. 29) or in other histopathology findings. NTTE offers a new radical procedure for resection of esophageal cancer combining a cervical video‐assisted approach and a transhiatal robotic approach. Although further accumulation of surgical cases is needed to corroborate these results, NTTE promises better prevention of pulmonary complications in the management of esophageal cancer.     

Mediastinoscopic esophagectomy for patients with early esophageal cancer

Objective

The purpose of this study was to detect the feasibility, safety, and effectiveness of mediastinoscopic esophagectomy for early esophageal cancer.

Methods

The clinical data of 194 patients who underwent mediastinoscopic esophagectomy for early esophageal cancer in our center from December 2005 to October 2014 were retrospectively analyzed.

Results

All the surgery was performed successfully. The average duration of thoracic surgery was 48.2±7.8 min and the average intra-operative blood loss was 128.1±34.5 mL. An average of 3.1±1.6 lymph node stations were dissected, with an average number of dissected lymph nodes being 9.38±6.2, among which 4.2±5.4 were mediastinal lymph nodes. No peri-operative mortality was noted, and the rate of peri-operative morbidity was 13.4%. The median duration of follow-up was 39 [3-108] months, and the overall survival was 72.73%. The overall survival rates significantly differed among different T stages; more specifically, the 5-year survival was 95.23% in patients with stage T_1a esophageal cancer, 70.15% for T_1b, and 55.56% for T₂ (P<0.001). The overall survival was significantly better in patients with negative lymph nodes than those with lymph nodes metastasis (P=0.003); more specifically, the 5-year survival rate was 84.9% for N₀, 62.5% for N₁, and 50.0% for N₂ + N₃.

Conclusions

The mediastinoscopic esophagectomy can achieve a similar effectiveness as the conventional thoracoscopic surgery for patients with early stage esophageal cancer.     

Incidence and impact of postoperative atrial fibrillation after minimally invasive esophagectomy

Atrial fibrillation (AF) following open esophagectomy has been associated with increased rates of pulmonary and anastomotic complications, and mortality. This study seeks to evaluate effects of AF after minimally invasive esophagectomy (MIE). A retrospective review of patients consecutively treated with MIE for esophageal carcinoma, dysplasia. and benign disease from November 2006 to November 2011 was performed. One hundred twenty‐one patients underwent MIE. Median age was 65 years (range 26–88) with 85% being male. Thirty‐eight (31.4%) patients developed AF postoperatively. Of these 38 patients, 7 (18.4%) had known AF preoperatively. Patients with postoperative AF were significantly older than those without postoperative AF (68.7 vs. 62.8 years, P = 0.008) and more likely to be male (94.7% vs. 80.7%, P = 0.04). Neoadjuvant chemoradiation showed a trend toward increased risk of AF (73.7% vs 56.6%, P = 0.07). Sixty‐day mortality was 2 of 38 (5.3%) in patients with AF and 4 of 83 (6.0%) in the no AF cohort (P = 1.00). The group with AF had increased length of hospitalization (13.4 days vs. 10.6 days P = 0.02). No significant differences in rates of pneumonia (31.6% vs. 21.7% P = 0.24), stricture (13.2% vs. 26.5% P = 0.10), or leak requiring return to operating room (13.2% vs. 8.4% P = 0.51) were noted between groups. We did not find an increased rate of AF in our MIE cohort compared with prior reported rates in open esophagectomy populations. AF did result in an increased length of stay but was not a predictor of other short‐term morbidities including anastomotic leak, pulmonary complications, stenosis, or 60‐day mortality.     

Examined lymph node count is not associated with prognosis in elderly patients with pN0 thoracic esophageal cancer

The purpose of this study was to determine whether the number of lymph nodes dissected predicts prognosis in surgically treated elderly patients with pN0 thoracic esophageal cancer. We searched the Surveillance, Epidemiology, and End Results database and identified the records of younger (<75 years) and older (≥75 years) patients with pN0 thoracic esophageal cancer between 1998 and 2015. The patient characteristics, tumor data, and postoperative variables were analyzed in this study. The Kaplan-Meier method and a Cox proportional hazard model were used to compare overall and cause-specific survival. Data from 1,792 esophageal cancer patients (older: n = 295; younger: n = 1497) were included. The survival analysis showed that the overall and cause-specific survival in the patients with ≥15 examined lymph nodes (eLNs) was significantly superior to that in the patients with 1 to 14 eLNs (P < .001); however, the difference disappeared in the older patients. After stratification by the tumor location, histology, pT classification, and differentiation between the younger and older cohorts to analyze the association between eLNs and survival, we found that the differences remained significant in most subgroups in the younger cohort. There were no differences in any subgroups of older patients. This study replicated the previously identified finding that long-term survival in patients with extensive lymphadenectomy was significantly superior to that in patients with less extensive lymphadenectomy. However, less extensive lymphadenectomy may be an acceptable treatment modality for elderly patients with pN0 thoracic esophageal cancer.     

Albert-Lembert versus hybrid-layered suture in hand sewn end-to-end cervical esophagogastric anastomosis after esophageal squamous cell carcinoma resection

Background

Hand sewn cervical esophagogastric anastomosis (CEGA) is regarded as preferred technique by surgeons after esophagectomy. However, considering the anastomotic leakage and stricture, the optimal technique for performing this anastomosis is still under debate.

Methods

Between November 2010 and September 2012, 230 patients who underwent esophagectomy with hand sewn end-to-end (ETE) CEGA for esophageal squamous cell carcinoma (ESCC) were analyzed retrospectively, including 111 patients underwent Albert-Lembert suture anastomosis and 119 patients underwent hybrid-layered suture anastomosis. Anastomosis construction time was recorded during operation. Anastomotic leakage was recorded through upper gastrointestinal water-soluble contrast examination. Anastomotic stricture was recorded during follow up.

Results

The hybrid-layered suture was faster than Albert-Lembert suture (29.40±1.24 min vs. 33.83±1.41 min, P=0.02). The overall anastomotic leak rate was 7.82%, the leak rate in hybrid-layered suture group was significantly lower than that in Albert-Lembert suture group (3.36% vs. 12.61%, P=0.01). The overall anastomotic stricture rate was 9.13%, the stricture rate in hybrid-layered suture group was significantly lower than that in Albert-Lembert suture group (5.04% vs. 13.51%, P=0.04).

Conclusions

Hand sewn ETE CEGA with hybrid-layered suture is associated with lower anastomotic leakage and stricture rate compared to hand sewn ETE CEGA with Albert-Lembert suture.     

Oxford experience with neoadjuvant chemotherapy and surgical resection for esophageal adenocarcinomas and squamous cell tumors

SUMMARY.  The Medical Research Council trial for oesophageal cancer (OEO2) trial demonstrated a clear survival benefit from neoadjuvant chemotherapy in resectable esophageal carcinoma. Since February 2000 it has been our practice to offer this chemotherapy regime to patients with T2 and T3 or T1N1 tumors. We analyzed prospectively collected data of patients who received neoadjuvant chemotherapy prior to esophageal resection under the care of a single surgeon. Complications of treatment and overall outcomes were evaluated. A total of 194 patients had cisplatin and 5-fluorouracil prior to esophageal resection. Six patients (5.7%) had progressive disease and were inoperable (discovered in four at surgery). During chemotherapy one patient died and one perforated (operated immediately). Complications including severe neutropenia, coronary artery spasm, renal impairment and pulmonary edema led to the premature cessation of chemotherapy in 12 patients (6.2%). A total of 182 patients with a median age of 63 (range 30–80), 41 squamous and 141 adenocarcinomas underwent surgery. Operations were 91 left thoracoabdominal (50%), 45 radical transhiatal (25%), 40 Ivor-Lewis (22%) and six stage three (3%), and 78.6% had microscopically complete (R0) resections. Median survival was 28 months with 77.3% surviving for 1 year and 57.7% for 2 year. In hospital mortality was 5.5% and anastomotic leak rate 7.7%. A radical surgical approach to the primary tumor in combination with OEO2 neoadjuvant chemotherapy has led to a high R0 resection rate and good survival with acceptable morbidity and mortality.
