Is hand sewing comparable with stapling for anastomotic leakage after esophagectomy? A meta-analysis

Risk factors for and treatment of anastomotic strictures after Ivor Lewis esophagectomy

INTRODUCTION

Anastomotic strictures following esophagectomy occur frequently and impact on nutrition and quality of life. Although strictures are often attributed to ischemia and anastomotic leaks, the role of anastomosis size and pyloroplasty is not well evaluated. Our study aims to assess the rate of and risk factors for anastomotic stricture following esophagectomy, and the impact of treatment with regular endoscopic balloon dilatations.

METHODS

Consecutive patients (n = 207) undergoing Ivor Lewis esophagectomy performed by two surgeons at our institution were included. Data on patient demographics, surgical outcomes and anastomotic strictures were recorded. Relationship of anastomotic strictures with circular stapler size, pyloroplasty and anastomotic leak was analyzed. Treatment of strictures with endoscopic balloon dilatation was reviewed and percentage weight loss at 1 year was evaluated.

RESULTS

Anastomotic strictures occurred in 17.4% of patients. Patient demographics between those with and without stricture were similar. Stricture rate was similar in patients with or without pyloroplasty (13.9% vs 21.7%, respectively, p = 0.14) and in those with or without an anastomotic leak (25.0% vs 16.6%, respectively, p = 0.345). Stricture risk increased with smaller sized stapler (25 mm = 33.3%, 28 mm = 15.3%, 31 mm = 4.8%; p = 0.027). The median number of dilatations required to fully treat strictures was 2 (IQR: 1-3). The median length of time from surgery to first dilatation was 2.9 months (IQR: 2.0-4.7) and to last dilatation was 6.1 months (IQR: 4.8-10.0). Median maximum dilatation diameter was 20 mm (IQR: 18.0-20.0). There were no complications from dilatations. Percentage weight loss at 1 year in patients with strictures was similar to those without strictures (8.7% vs 11.1%, respectively, p = 0.090).

CONCLUSIONS

Post-esophagectomy anastomotic strictures are common and not necessarily related to anastomotic leaks or absence of pyloroplasty. Smaller anastomosis size was strongly linked with stricture formation. A driven approach with regular endoscopic balloon dilation is safe and effective in treating these strictures with no excess weight loss at 1 year once treated.

Risk Factors of Anastomosis Stricture After Esophagectomy and the Impact of Anastomosis Technique

BACKGROUND

Anastomosis complications after esophagectomy are related to postoperative survival and quality of life. This is a retrospective observational study to identify risk factors for anastomotic stricture after esophageal cancer surgery and the effect of different anastomosis techniques on stricture development.

METHODS

This study included 737 patients who underwent esophagectomy for esophageal cancer that used stomach conduits. Four types of anastomoses were used: manual sewing (n = 221, 30%), circular stapling (n = 172, 23%), hybrid linear stapling with a 45-mm stapler (HLS; n = 155, 21%), and triangular linear stapling with 60-mm staplers (TLS; n = 189, 26%). Multivariate analysis was performed to evaluate the risk factors for stricture.

RESULTS

Strictures that required endoscopic dilatation within 1 year after surgery occurred in 105 patients (14%), and 13% of the strictures were related to leakage. Multivariate analysis revealed that chronic obstructive pulmonary disease (hazard ratio [HR] 1.726, P = .017), leakage (HR 2.502, P = .015), and anastomosis techniques other than TLS (manual sewing: HR 9.588; circular stapling: HR 6.516; HLS HR 5.462, all P < .001) were significant risk factors for stricture. TLS significantly reduced the stricture rate (3.2%) compared with other techniques (manual sewing: 22.2%; circular stapling:, 14.5%; HLS: 16.1%; P < .001). Stricture rate was lower in the TLS group in patients without leakage (P < .001); however, the effect disappeared with leakage.

CONCLUSIONS

Anastomosis stricture occurred in 14% of esophagectomy patients. Chronic obstructive pulmonary disease, leakage, and anastomosis technique are risk factors for stricture. A large anastomosis area with the TLS technique using 60-mm length linear staplers prevented stricture, especially when leakage was not observed.

Why pay more for robot in esophageal cancer surgery?

Esophagectomy is the gold standard for the treatment of resectable esophageal cancer. Traditionally, it is performed through a laparotomy and a thoracotomy, and is associated with high rates of postoperative complications and mortality. The advent of robotic surgery has represented a technological evolution in the field of esophageal cancer treatment. Robot-assisted Minimally Invasive Esophagectomy (RAMIE) has been progressively widely adopted following the first reports on the safety and feasibility of this procedure in 2004. The robotic approach has better short-term postoperative outcomes than open esophagectomy, without jeopardizing oncologic radicality. The results of the comparison between RAMIE and conventional minimally invasive esophagectomy are less conclusive. This article will focus on the role of RAMIE in the current clinical scenario with particular attention to its possible benefits and perspectives.

Robotic versus thoraco-laparoscopic minimally invasive Ivor Lewis esophagectomy, a matched-pair single-center cohort analysis

Minimally invasive esophagectomy (MIE) is becoming more widespread with a documented improvement in postoperative morbidity based on level I evidence. However, there is a lack of consensus regarding the optimal MIE approach, conventional thoracoscopy/laparoscopy vs robotics as well as the ideal anastomotic technique. All patients who underwent MIE via an Ivor Lewis approach with a side-to-side stapled anastomosis were included. The thoracoscopy-laparoscopy (TL) group was compared to the robotic group with respect to perioperative outcomes using the entire cohorts and after 1:1 propensity score matching. Comparisons were made using the Mann-Whitney U and Fisher's exact tests. Between July 2013 and November 2020, 72 TL and 67 robotic Ivor Lewis MIE were performed. After comparing the two unadjusted cohorts and 51 propensity matched pairs, there was a decrease in Clavien-Dindo Grade 2 or above complications in the robotic vs TL group (59.7% vs 41.8% [P = 0.042], (62.7% vs 39.2% [P = 0.029]), respectively. In both analyses, there was a reduction in hospital length of stay (median of 8 vs 7 days, P < 0.001) and a trend toward less anastomotic leaks in the robotic group (Unadjusted: 12.5 vs 3% [P = 0.057], Propensity-matched analysis: 13.7% vs 3.9% [P = 0.16]), respectively. A clinically significant decrease in overall morbidity, cardiac complications and hospital length of stay was observed in the robotic Ivor Lewis cohort when compared with the TL group at a high volume MIE program. Side-to-side stapled thoracic anastomoses utilizing a robotic platform provides the best outcomes in this single institution experience.

Effect of Circular Stapler Diameter on Anastomotic Leakage Rate and Stenosis After Open Total Gastrectomy With Esophagojejunostomy: A Substantive Retrospective Propensity Score Matched Series

Background

Anastomotic leakage (AL) and stenosis (AS) are two of the most severe postoperative complications after total gastrectomy with esophagojejunostomy. The stapler diameter can be chosen by the surgeon. Therefore, this study aims to assess the correlation between the stapler size as main independent variable as well as other different risk factors and AL and AS.

Methods

We conducted a retrospective analysis of data from 356 patients who underwent open total gastrectomy between 2000 and 2018, mostly due to gastric cancer (96.9%). After propensity score matching the outcome parameters AL and AS were compared between the two stapler size groups. We also assessed different risk factors for AL and AS in cancer patients using multivariate analysis.

Results

Small circular stapler diameter (21/25 mm; n = 147 vs 28/29/31 mm; n = 209) was identified as a significant risk factor for the occurrence of AL (10% vs 4% for smaller vs larger staplers; P = 0.042). In multivariate analysis for the occurrence of AL an ASA score ≥ 3 could be identified as a risk factor (OR 2.85; 95% CI = 1.13-7.15; P = 0.026). Additionally, smaller stapler size could be identified as a risk factor for AS (OR small 1.00, OR large 0.24; 95% CI: 0.06-0.97; P = 0.045). AL was associated with lower survival (18.1 vs 38.16 months; P = 0.0119).

Conclusion

The application of a larger circular stapler for esophagojejunostomy in open total gastrectomy shows significantly lower rates of AL and stenosis. Therefore, the largest possible stapler diameter should be applied.

End to side circular stapled anastomosis during robotic-assisted Ivor Lewis minimally invasive esophagectomy (RAMIE)

Robotic-assisted minimally invasive esophagectomy (RAMIE) represents an established approach for the treatment of esophageal cancer. Aim of this study is to evaluate the feasibility and safety of our technique for performing the intrathoracic anastomosis during RAMIE.All the procedures were performed by the same surgeon using the same technique for performing the intrathoracic anastomosis. Intraoperative and postoperative outcomes were recorded. Postoperative complications were classified according to the Esophagectomy Complications Consensus Group (ECCG); the primary outcome was the evaluation of the feasibility and safety of our technique. From 2016 to 2021, 204 patients underwent Ivor Lewis RAMIE at our Center. Two patients (0.9%) were converted during the thoracic phase. The anastomosis was completed in all the other patients forming complete anastomotic rings. The median duration for the robotic-assisted thoracoscopic phase was 224 minutes. Twenty-two of the RAMIE-Ivor Lewis patients had an anastomotic leakage (10.3%). The overall 90-day postoperative mortality was 1.9%. The procedure resulted to be feasible and safe in our cohort of patients.

Circular vs. linear stapling after minimally invasive and robotic-assisted esophagectomy: a pooled analysis

Purpose

Current data states that most likely there are differences in postoperative complications regarding linear and circular stapling in open esophagectomy. This, however, has not yet been summarized and overviewed for minimally invasive esophagectomy, which is being performed increasingly.

Methods

A pooled analysis was conducted, including 4 publications comparing linear and circular stapling techniques in minimally invasive esophagectomy (MIE) and robotic-assisted minimally invasive esophagectomy (RAMIE). Primary endpoints were anastomotic leakage, pulmonary complications, and mean hospital stay.

Results

Summarizing the 4 chosen publications, no difference in anastomotic insufficiency could be displayed (p = 0.34). Similar results were produced for postoperative pulmonary complications. Comparing circular stapling (CS) to linear stapling (LS) did not show a trend towards a favorable technique (p = 0.82). Some studies did not take learning curves into account. Postoperative anastomotic stricture was not specified to an extent that made a summary of the publications possible.

Conclusions

In conclusion, data is not sufficient to provide a differentiated recommendation towards mechanical stapling techniques for individual patients undergoing MIE and RAMIE. Therefore, further RCTs are necessary for the identification of potential differences between LS and CS. At this point in research, we therefore suggest evading towards choosing a single anastomotic technique for each center. Momentarily, enduring the learning curve of the surgeon has the greatest evidence in reducing postoperative complication rates.

Mechanical triangular esophagogastrostomy: Technical aspects and initial results

INTRODUCTION

Esophageal cancer represents the eighth neoplasm worldwide. The therapeutic approach is interdisciplinary, with surgery being the most effective option. Several techniques have been proposed to perform esophagogastrostomy after esophagectomy, among them mechanical triangular esophagogastrostomy (MT), with a little experience published in the Western literature on the latter. The objective of this study is to describe the technical aspects and initial results of MT anastomosis.

METHODS

A retrospective review of the patients who underwent esophagectomy according to the McKeown technique was performed, those in which MT anastomosis was implemented, between October 2017 and March 2020 in our hospital.

RESULTS

14 patients were included, with a mean age of 63 years. The mean operative time was 436 min (360-581), being diagnosed of anastomotic leak (AL) 3 of the 14 patients (21.4%), as well as 3 patients presented anastomotic stenosis (AS). The median stay was 20 days, without any death in the series.

DISCUSSION

Multiple publications suggest the superiority in terms of AL and AS of the mechanical triangular anastomosis, which was also observed in our series, in which despite the small sample, a rapid improvement was observed in the indicators after the first cases. Therefore, this type of anastomosis may be a safe option for performing esophagogastric anastomosis after esophagectomy, being necessary more definitive conclusive studies.

Robotic-assisted Ivor Lewis esophagectomy, a review of the technique

Esophageal resection is a key component of the multidisciplinary management of esophageal cancer. Robotic-assisted minimally invasive esophagectomy is gaining widespread approval amongst few centers with promising early data. There is significant variability in the operative approach utilized by different centers and this review describes, step-by-step, the operative technique at a high-volume tertiary center. The cornerstone of management is individualized surgical approach, based on patient, tumor and technical factors. Although our approach is based on aforementioned factors, our preferred approach is an Ivor Lewis esophagectomy and this review focuses on that. The procedure is broken down into three key parts, starting with an abdominal exploration and creation of the gastric conduit, placement of jejunostomy tube, moving to thoracic mobilization and creation of the side-side 6 cm stapled esophagogastric anastomosis with a final abdominal portion to assure proper positioning of the conduit and reducing redundancy. This approach is fully robotic and a side to side anastomosis facilitates the creation of a widely patent anastomosis therefore minimizing the risk of anastomotic leaks and strictures. Our experience with minimally invasive esophagectomy, as has been previously published, is associated with a 5.1% of anastomotic leak and 7.6% of anastomotic stricture. The robotic platform further optimizes this technique and helps us safely accomplish a side to side stapled anastomosis. Superior instrument dexterity in a restricted thoracic space is facilitated by intracorporeal suturing and robotic stapling. Thus, it obviates the need for a larger thoracotomy incision, which is typically needed for an EEA anastomosis, and that is traditionally associated with higher stricture rate.

Minimally invasive esophagectomy: clinical evidence and surgical techniques

Background

Surgical esophagectomy plays a crucial role in the curative and palliative treatment of esophageal cancer. Thereby, minimally invasive esophagectomy (MIE) is increasingly applied all over the world. Combining minimal invasiveness with improved possibilities for meticulous dissection, robot-assisted minimal invasive esophagectomy (RAMIE) has been implemented in many centers.

Purpose

This review focuses on the development of MIE as well as RAMIE and their value based on evidence in current literature.

Conclusion

Although MIE and RAMIE are highly complex procedures, they can be performed safely with improved postoperative outcome and equal oncological results compared with open esophagectomy (OE). RAMIE offers additional advantages regarding surgical dissection, lymphadenectomy, and extended indications for advanced tumors.

Anastomotic techniques for oesophagectomy for malignancy: systematic review and network meta-analysis

Background

Current evidence on the benefits of different anastomotic techniques (hand‐sewn (HS), circular stapled (CS), triangulating stapled (TS) or linear stapled/semimechanical (LSSM) techniques) after oesophagectomy is conflicting. The aim of this study was to evaluate the evidence for the techniques for oesophagogastric anastomosis and their impact on perioperative outcomes.

Methods

This was a systematic review and network meta‐analysis. PubMed, EMBASE and Cochrane Library databases were searched systematically for randomized and non‐randomized studies reporting techniques for the oesophagogastric anastomosis. Network meta‐analysis of postoperative anastomotic leaks and strictures was performed.

Results

Of 4192 articles screened, 15 randomized and 22 non‐randomized studies comprising 8618 patients were included. LSSM (odds ratio (OR) 0·50, 95 per cent c.i. 0·33 to 0·74; P = 0·001) and CS (OR 0·68, 0·48 to 0·95; P = 0·027) anastomoses were associated with lower anastomotic leak rates than HS anastomoses. LSSM anastomoses were associated with lower stricture rates than HS anastomoses (OR 0·32, 0·19 to 0·54; P < 0·001).

Conclusion

LSSM anastomoses after oesophagectomy are superior with regard to anastomotic leak and stricture rates.

Correlation between indocyanine green visualization time in the gastric tube and postoperative endoscopic assessment of the anastomosis after esophageal surgery

PURPOSE

To evaluate the correlation between blood supply speed in the gastric tube (GT), assessed by the intraoperative indocyanine green (ICG) fluorescence method, and postoperative endoscopic assessment (PEA) of the anastomosis or anastomotic leakage (AL).

METHODS

The subjects of this retrospective analysis were 66 consecutive patients who underwent GT reconstruction using ICG fluorescence during esophageal surgery. We measured the ICG visualization time, from ICG injection to visualization at the top of the GT. We performed PEA on 54 patients and classified ulcer formation as involving less than or more than half of the circumference.

RESULTS

PEA revealed that nine patients (16.7%) had an anastomotic ulcer involving more than half of the circumference and ten (15.4%) had AL. The ICG visualization time in these patients was significantly delayed compared with that in those with less than half of the circumference involved by ulcer formation (37 s vs. 27 s; P = 0.015) and without AL (36 s vs. 28 s; P = 0.045). Multivariate analysis revealed that delay in the ICG visualization time (> 36 s) of the pulled-up GT (odds ratio, 6.098; 95% confidence interval, 1.125-33.024; P = 0.036) was an independent risk factor associated with AL.

CONCLUSION

Delay in the ICG visualization time of pulled-up GT was associated with ulcer formation on the anastomosis and AL after esophageal surgery.

The Bucharest ESTES consensus statement on peritonitis

INTRODUCTION

Peritonitis is still an important health problem associated with high morbidity and mortality. A multidisciplinary approach to the management of patients with peritonitis may be an important factor to reduce the risks for patients and improve efficiency, outcome, and the cost of care.

METHODS

Expert panel discussion on Peritonitis was held in Bucharest on May 2017, during the 17th ECTES Congress, involving surgeons, infectious disease specialists, radiologists and intensivists with the goal of defining recommendations for the optimal management of peritonitis.

CONCLUSION

This document is an updated presentation of management of peritonitis and represents the summary of the final recommendations approved by a panel of experts.

Performance of the transoral circular stapler for oesophagogastrectomy after induction therapy

OBJECTIVES

Patients undergoing oesophageal anastomosis may be at an increased risk for leak after induction therapy for oesophageal cancer, with intrathoracic leaks having significant morbidity. The outcomes of utilizing transoral circular stapler for the creation of a thoracic anastomosis have not been well studied in this patient population.

METHODS

Patients with oesophageal cancer undergoing induction chemotherapy/radiation followed by Ivor Lewis oesophagogastrectomy were evaluated. All thoracic anastomoses were constructed with transoral circular stapler. Primary outcomes evaluated were the rates of anastomotic leak and stricture.

RESULTS

Over 7 years, 87 consecutive patients were evaluated, among whom 69 (79%) were male. The median age was 63 years, median body mass index (BMI) was 27 kg/m2 and median age-adjusted comorbidity index was 5. Median operative blood loss was 400 ml and median operative time was 300 min. Major complications (grade ≥3) were seen in 19 (22%), including anastomotic leak in 2 (2.3%), both successfully treated with temporary covered metal stent. The median duration of hospital stay was 10 days, and 1 (1.2%) death was reported at 90 days due to cancer recurrence. Stricture occurred in 8 (9.2%), and median time to dilation was 109 days and median number of dilations was 1. Univariable analysis found BMI to be significantly higher in patients with an anastomotic leak versus those without (43 vs 27 kg/m2, P = 0.002). No variables were found to be predictive of anastomotic stricture.

CONCLUSIONS

The use of the transoral circular stapler for thoracic anastomosis results in a consistent formation of the anastomosis, with low leak and stricture rates in the setting of induction chemotherapy/radiation. Leaks that do occur appear to be amenable to stent therapy.

A Technical Modification to the Circular Stapling Anastomosis Technique During Minimally Invasive Ivor Lewis Procedure

Background: The circular stapled (CS) technique with transoral placement of the anvil is commonly used to perform the esophagogastric anastomosis during minimally invasive esophagectomy (MIE). The procedure is safe, efficient, and highly reproducible; however, the intersection between the circular plane of the stapler and the linear staple line of the esophageal stump can expose the anastomosis to the formation of dog-ears and, therefore, increase the risk of anastomotic leak (AL). We describe a simple modification of the CS technique that consists of folding the linear esophageal transection line with a stitch around the anvil shaft, to include the staple line in the resection during the EEA^™ firing. Methods: We prospectively collected data on a small group of patients who underwent MIE for cancer using our modified CS technique. Feasibility has been evaluated as the percentage of cases in which the modified anastomosis technique has been carried out successfully with the formation of a complete anastomotic ring. Safety has been defined as the absence of procedure-related complications. Results: MIE was performed in 10 patients using our modified CS technique. All the procedures were successfully completed with complete resection of the linear esophageal staple line and no intraoperative complications. Only one patient developed a postoperative AL that was only detected by barium swallow and did not cause any symptom or clinical sign. Conclusion: Our modified CS technique is feasible and did successfully prevent the occurrence of clinically relevant ALs in this small case series of patients.

Robot-assisted minimally invasive esophagectomy (RAMIE) improves perioperative outcomes: a review

Robotic assisted minimal invasive esophagectomy (RAMIE) is increasingly applied as a clinically and oncologically safe technique in the surgical treatment of esophageal cancer. This review focuses on the advantages and potential opportunities of RAMIE to improve the perioperative and oncological outcomes based on the evidence from current literature. In addition, critical notes on aspects such as procedure duration and costs are addressed in this paper.

Early outcomes of two-stage minimally invasive oesophagectomy in an Australian institution

BACKGROUND

Minimally invasive oesophagectomy (MIO) has a steep learning curve. We report our outcomes of a standardized 25 mm circular-stapled anastomosis using a trans-orally placed anvil (Orvil™). The objective of this study is to report the initial experience of introducing two-stage MIO to an Australian tertiary health service.

METHODS

We describe our consecutive case series of all MIOs performed from a prospectively maintained database. We assessed the morbidity and mortality of MIO at our institution. We compared our first 30 cases to the second cohort of 32 cases.

RESULTS

There were 62 two-stage MIOs performed from 2011 to 2015. The average age was 65 years. Median length of stay was 13 days (5-72 days). Median number of total lymph nodes was 14. Conversion occurred in three patients (5%). Major morbidity was 45%. Delayed gastric emptying 6% (n = 4), pneumonia 6% (n = 4), chyle leak 6% (n = 4), pulmonary embolus 2% (n = 1) and grade II or III anastomotic leak 5% (n = 4). One conduit ischaemia (2%) required reoperation and formation of oesophagostomy. There was one post-operative death within 30 days. There were five post-oesophagectomy hiatal hernias requiring re-operation (8%). There was a significant improvement in operative time (minutes) from the first to second cohort 588 versus 464 (P-value 0.01).

CONCLUSION

The introduction of two-stage MIO to the Australian setting can be safely instituted. Our unit was still within a learning curve after 30 cases.

Towards optimal intraoperative conditions in esophageal surgery: A review of literature for the prevention of esophageal anastomotic leakage

BACKGROUND

Esophageal anastomotic leakage (EAL) is a severe complication following gastric and esophageal surgery for cancer. Several non-modifiable, patient or surgery related risk factors for EAL have been identified, however, the contribution of modifiable intraoperative parameters remains undetermined. This review provides an overview of current literature on potentially modifiable intraoperative risk factors for EAL.

MATERIALS AND METHODS

The PubMed, EMBASE and Cochrane databases were searched by two researchers independently. Clinical studies published in English between 1970 and January 2017 that evaluated the effect of intraoperative parameters on the development of EAL were included. Levels of evidence as defined by the Centre of Evidence Based Medicine (CEBM) were assigned to the studies.

RESULTS

A total of 25 articles were included in the final analysis. These articles show evidence that anemia, increased amount of blood loss, low pH and high pCO2 values, prolonged duration of procedure and lack of surgical experience independently increase the risk of EAL. Supplemental oxygen therapy, epidural analgesia and selective digestive decontamination seem to have a beneficial effect. Potential risk factors include blood pressure, requirement of blood products, vasopressor use and glucocorticoid administration, however the results are ambiguous.

CONCLUSION

Apart from fixed surgical and patient related factors, several intraoperative factors that can be modified in clinical practice can influence the risk of developing EAL. More prospective, observational studies are necessary focusing on modifiable intraoperative parameters to assess more evidence and to elucidate optimal values of these factors.

Expedite recovery from esophagectomy and reconstruction for esophageal squamous cell carcinoma after perioperative management protocol reinvention

BACKGROUND

Surgery for esophageal cancer is invasive and challenging, and always to be followed with arduous post-operative care and recovery. This study, maybe one of the first in Asian populations, is to determine whether a reinvented protocol for perioperative management for esophageal cancer surgery which is being implemented in our department, will lead to a faster convalescence and also significantly decrease financial burdens garnered by patients during hospitalization.

METHODS

Operated on by the same surgeon and team in the same hospital, consecutive patients who had received esophagectomy and reconstruction for esophageal squamous cell carcinoma were retrospectively reviewed. On the basis of two different treatment periods, patients were divided into two groups: A and B. Group A was patients who had received the new reinvented protocol between 2012 and 2016, while group B patients were those having received the previous protocol between 2008 and 2011. Their demographics, post-operative outcome, and hospital charges were collected and compared.

RESULTS

There were 64 patients in group A, and 69 in group B. Ventilator days (P<0.001), ICU stay (P<0.001), and post-operative stay (P<0.001) were significantly shorter in group A patients. Complication rates were similar between the two groups. No hospital mortality was noted in either group. Hospital charges in group A were found to be perceptively lower, although not statistically significant (P value =0.078).

CONCLUSIONS

The current protocol of perioperative care effectively ameliorated convalescence after esophagectomy and reconstruction for esophageal squamous cell carcinoma without increasing complication rate or mortality. It is also potentially more practical in future health care policies during this era of financial shortage.
