Introduction
The aim of surgical treatment of any condition is to relieve and/or abolish symptoms and to prevent progression of the disease with the lowest complication and mortality rates possible. Subtotal esophagectomy without thoracotomy has been proposed as the best surgical approach to the treatment of advanced megaesophagus.
Radiologically, advanced megaesophagus is characterized by elongation of the esophagus and axis deviation in relation to the spine (dolichol-megaesophagus). From a functional point of view, advanced megaesophagus is defined when manometry reveals a contraction wave amplitude of the esophagus less than 20 mmHg, regardless of esophageal diameter11 Crema E, Cruvinel LAF, Werneck AM, Oliveira RM, Silva AA. Correlação manométrico-radiológica e sua importância no tratamento cirúrgico do megaesôfago chagásico. Rev Soc Bras Med Trop. 2003;36(6):665-9. doi: 10.1590/S0037-86822003000600004.

. In the advanced forms, the esophagus becomes an inert pouch, which almost always exhibits stasis. Consequent chronic dysplastic and/or neoplastic alterations in the esophageal wall are observed at a rate that is up to 140 times higher than that seen in the general population22 Brücher BL, Stein HJ, Bartels H, Feussner H, Siewert JR.

Historically, Câmara Lopes and Ferreira Santos used subtotal esophagectomy by cervicotomy, right thoracotomy and laparotomy as surgical approaches to the treatment of advanced megaesophagus88 Pinotti HW, Zilberstein B, Pollara W, Raia A.

PMID: 9629316.proposed subtotal esophagectomy using a laparoscopic and transmediastinal approach for preparation of the stomach and dissection of the abdominal and thoracic esophagus, and left cervicotomy for removal of the specimen and esophagogastric anastomosis, a widely used technique for the treatment of advanced megaesophagus in referral centers.
The truncal vagotomy performed during esophagectomy leads to high rates of chronic diarrhea, Dumping syndrome, gastric emptying problems, weight loss, and cholelithiasis. A decrease in the inflammatory response resulting from inflammatory sepsis has also been described. The use of the laparoscopic approach and preservation of the vagal trunks have substantially improved the outcomes of esophagectomy during the early and late postoperative period, maintaining gastric emptying and pancreatic and gastric secretion close to preoperative values. Indications for subtotal esophagectomy with preservation of the vagal trunks include high-grade dysplastic lesions, intramucosal carcinoma, Barret’s esophagus with high-grade dysplasia, and advanced or relapsed megaesophagus.
The objective of this study was to evaluate the outcome of transhiatal esophagectomy without thoracotomy and with preservation of the vagal trunks for the treatment of advanced megaesophagus.
Methods
The patients received information about the surgical procedure performed and the study protocol was approved by the Ethics Committee on Research Involving Humans of the Universidade Federal do Triângulo Mineiro.
Between March 2006 and September 2017, we performed 136 transhiatal esophagectomies without thoracotomy by laparoscopy, with preservation of the vagus nerves. Of these, 123 (90.45%) patients had chagasic megaesophagus and 13 (9.55%) had idiopathic megaesophagus. The mean age was 59.3 (17-79) years and 81 (59.55%) patients were male.
Before surgery, all patients were submitted to Trypanosoma cruzi serology, esophageal contrast examination, upper endoscopy, electromanometry, 24-hour pH monitoring, and gallbladder ultrasonography. Pre- and postoperative nutritional and physiotherapeutic assessments were performed on all patients. The following data were obtained: anthropometric (weight, height, arm muscle circumference, skinfold, and creatinine/height index), biochemical (total proteins, albumin, and transferrin), immunological (total lymphocytes and tuberculin purified protein derivative), and physiotherapeutic. All patients were submitted to ambulatory preoperative preparation for 7 to 21 days, which consisted of respiratory physiotherapy and enteral nutrition support (1.5g protein/kg/day) through a nasoenteral tube placed into the stomach.
Preoperative preparation
Clinical evaluation, especially cardiological, pulmonary and nutritional assessment, should be performed routinely since patients with megaesophagus usually exhibit comorbidities and are malnourished at the time of treatment. The evaluation of gastric emptying time by Tc99 scintigraphy and with barium contrast introduced through the tube placed into the stomach is important to rule out an association with megastomach, which is observed at our service in 8% of patients with chagasic megaesophagus.
Abdominal ultrasonography is also useful for the diagnosis of cholelithiasis, which is associated with chagasic megaesophagus in 14 to 26% of cases1313 Rocha A, Almeida H, Teixeira VPA, Silva AM.

World J Surg. 1991;15(2):198-204. PMID: 1903232.. In a study conducted at our service, cholelithiasis was associated with chagasic megaesophagus in 28.5% of the patients1515 Crema E, Silva ECRS, Franciscon PM, Rodrigues Júnior V, Martins Júnior A, Teles CJO, Silva AA.

.
On the day before surgery, a thick Fouchet or Levin oroesophageal catheter is passed and the esophagus is cleaned mechanically with 0.9% saline.
Surgical technique
The position of the patient is the same as that used for laparoscopic esophagocardiomyotomy. The patient is placed in the lithotomy position, with the legs extended, separated and adequately supported on a leg holder. The surgeon stands between the legs and the assistants on the left side of the patient (camera and presentation). The monitor, if only one, is positioned at the headrest to the right of the operating table.
Five ports are used: a) a 10-mm trocar placed above the umbilical scar, approximately 15 cm from the xiphoid appendix (30-degree optics); b) a 10-mm trocar placed in the left subcostal region at the midclavicular line (right hand of the surgeon); c) a 5-mm trocar placed in the right subcostal region at the midclavicular line (left hand of the surgeon); d) a 5-mm trocar placed in the midline subxiphoid position (assistant separating the left lobe of the liver), and e) a 5-mm trocar placed to the left of the scar (assistant pushing the junction and esophagus), with a 5-mm trocar being sufficient. When associated with cholelithiasis, the fifth port can be placed to the right, facilitating presentation of the gallbladder at the time of cholecystectomy.
At a pneumoperitoneum of 12 mmHg, the procedure is initiated by opening the phrenoesophageal membrane and greater omentum, providing access to the right branch of the right pillar of the diaphragm. From this point onwards, the periesophageal tissue is released around the terminal esophagus, isolating the esophagus by dissection of the gastroesophageal junction and repairing the abdominal esophagus with a Penrose drain. The anterior and posterior vagal trunks are identified and isolated. Dissection of the vagal trunks until the gastroesophageal junction is important when choosing vagus nerve preservation during esophageal resection (Figures 1 and 2). At this stage, dissection is continued under direct vision of the esophageal body, identifying the pleura, pericardium, azygos vein and vagal trunks throughout the thoracic extension. Hemostasis is performed by monopolar cauterization and/or clipping of the greater esophageal branches, but an ultrasonic scalpel is the preferred method and is frequently used. It is important that the surgical plane is close to the esophagus to avoid injury to the pleura and mediastinal structures. For better access to the mediastinum during dissection of the thoracic esophagus, we perform a midline transection of the diaphragm and place the operating table in the Trendelenburg position, as used in the abdominal cervical approach during open surgery.

After dissection of the abdominal and thoracic esophagus is completed, the stomach is prepared with release of the greater curvature. Mono- or bipolar electrocautery or, preferentially, a harmonic scalpel is used for sectioning of the short vessels and of the gastrocolic omentum. Double clipping is used for ligation of the gastroepiploic artery and vein and of the left gastric artery and vein, preserving the arcade of the greater and lesser curvature.
We do not perform pyloroplasty during surgical treatment of advanced megaesophagus in the case of chagasic or idiopathic esophagopathy. Once preparation of the stomach is complete, dissection of the cervical esophagus is performed by left cervicotomy. By gently pushing the surgical specimen, the esophagus and proximal part of the stomach in the cervical region are exteriorized and the gastroesophageal junction is cut with a linear cutting stapler with a green load. During cervical traction of the previously dissected esophagus, the passage of the esophagus and stomach through the mediastinum must be monitored under direct vision with the optic placed in the inferior mediastinum.
An esophagogastric anastomosis is performed with manual continuous polypropylene monofilament suture in a single plane. A nasoenteral tube is placed into the duodenum, when possible, or into the gastric antrum for enteral feeding as described for preoperative preparation, 24 hours after the surgical procedure. We do no use cervical or abdominal drainage.
It should be noted that dissection of the anterior and posterior vagal trunks should be performed before dissection of the esophagus and preparation of the stomach to avoid inadvertent sectioning of the vagal trunks during the cervical time. The absence of pyloroplasty in patients with megaesophagus who do not have megastomach prevents the reflux of duodenal content to the stomach, which is now positioned in the posterior mediastinum, a region of negative pressure. Another important factor is that the esophagogastric anastomosis remains in the cervical region, which is characterized by positive pressure, thus preventing the reflux of gastric fluid into the esophagus and consequent esophagitis. The latter may occur when the anastomosis is in an intrathoracic position.
The use of the whole stomach as a plasty organ is justified by the better vascularization of the gastric fundus since it avoids interruption of the submucosal vascular network of the gastric body and fundus, maintaining the vascular communication with the arcade of the lesser and greater curvature. Thus, maintenance of the gastric innervation is also facilitated.
Results
The mean duration of surgery was 120 minutes (90-150) and improvement was observed in all parameters analyzed. Only five patients (8.34%) required ventilation support after surgery and three received blood transfusion during or after surgery. Early complications were observed in 19 patients (13.97%). There were nine cases (6.61%) of hemopneumothorax that required a peri- or postoperative chest drain. Early gastric stasis (3 months) was observed in three cases (2.2%), a cervical fistula in five (3.67%), which resolved clinically by exclusive enteral nutrition and cervical drainage through removal of the cervical incisions, and dysphonia in eight (5.88%). Late complications occurred in 10 cases (7.35%). Five patients (3.67%) had dysphonia that improved only after 3 months. Dysphagia due to anastomotic stricture was observed in four cases (2.94%), three of them requiring endoscopic dilatation and one submitted to plasty of the anastomosis.
When gastric emptying was compared with the historical series in which the vagus nerve was not preserved, we found early gastric emptying problems in three (2.2%) of the 136 cases with vagus nerve preservation and in eight (8.42%) of the 95 cases without preservation, with this difference being statistically significant. Late gastric stasis was not observed in any case of the group with vagus nerve preservation and in four cases (4.21%) without preservation.
Two patients (1.47%) died, one patient with a pacemaker due to cardiac arrhythmia on postoperative day 12 and one due to mediastinitis on postoperative day 28.
Histopathological examination of the surgical specimen and polymerase chain reaction (PCR) for T. cruzi confirmed chagasic esophagopathy in 123 cases (90.45%) and idiopathic disease in 13 (9.55%). Cases with associated neoplasms diagnosed before surgery or in the surgical specimen were excluded from this series.
Contrast examination of the esophageal stump, stomach and duodenum was performed 10 days, 3 months and one year after surgery and revealed the presence of the esophagogastric anastomosis in the cervical region, good passage of the contrast through the anastomosis, and good gastric emptying. Endoscopy performed 3 months and one year after surgical treatment detected 20 cases (14.7%) of mild esophagitis in the esophageal stump, although manometry showed that the anastomosis was situated in a high-pressure region and 24-hour pH monitoring with the sensor placed 2 cm above the esophagogastric anastomosis did not detect acid reflux in any patient.
Follow-up for 7 months to 12 years by clinical, radiologic, endoscopic and pH monitoring revealed satisfactory and encouraging outcomes of the procedure.
Discussion
The choice of the most appropriate technique for the treatment of megaesophagus is based on the stage of esophagopathy. In the non-advanced stage, cardiomyotomy combined with a partial antireflux valve has been found to be the best surgical option.
In the advanced stage of esophagopathy, contrast examination reveals an esophageal diameter of 10 cm and/or tortuosity of the esophagus with axis deviation (dolichol-esophagus)1616 Rezende JM, Lauar KM, Oliveira AR. Aspectos clínicos e radiológicos da aperistalse do esôfago. Rev Bras Gastroenterol. 1960;12(2):247-62.,1717 Herbella FAM, Del Grange JC, Lourenço LG, Mansur NS, Haddad CM.

From a functional point of view, megaesophagus is characterized manometrically by a contraction wave amplitude of the body of less than 20 mmHg. Previous studies have shown peristaltic waves less than 20 mmHg in all patients with radiologically advanced megaesophagus11 Crema E, Cruvinel LAF, Werneck AM, Oliveira RM, Silva AA. Correlação manométrico-radiológica e sua importância no tratamento cirúrgico do megaesôfago chagásico. Rev Soc Bras Med Trop. 2003;36(6):665-9. doi: 10.1590/S0037-86822003000600004.
https://doi.org/10.1590/S0037-8682200300...
, while 38.4% of patients with radiologically non-advanced megaesophagus have low-amplitude waves. These patients were therefore classified as functionally advanced megaesophagus.
Surgical treatment of this form of the disease (non-advanced stage) using any technique targeting the gastroesophageal junction has shown unsatisfactory results1818 Loviscek LF, Cenoz MC, Badaloni AE, Agarinakazato O. Early cancer in achalasia. Dis Esophagus. 1998;11(4):239-47. PMID: 10071806.; therefore, subtotal esophagectomy with removal of this inert pouch filled with stasis fluid rich in enterobacteria33 Crema E, Madureira AB, Lima VGF, Castro AMV, Silva AA, Junqueira IS. Estudo da microflora do megaesôfago chagásico. Rev Soc Bras Med Trop. 2002;35(1):39-42.

Arch Surg. 1997;132(9):943-7. PMID: 9301605..
The advent of the laparoscopic approach has led to a reduction in pulmonary dysfunction and consequently in postoperative complications, which had reached rates of 30%1010 DePaula AL, Hashiba K, Ferreira EAB, de Paula RA, Grecco E. Laparoscopic transhiatal esophagectomy with esophagogastroplasty. Surg Laparosc Endosc. 1995;5(1):1-5.

In a meta-analysis of 17 articles involving 1.422 patients submitted to esophagectomy, Aiolfi et al.2020 Aiolfi A, Asti E, Bonitta G, Bonavina L. Esophageal resection for end-stage achalasia. Am Surg. 2018. Apr 1;84:506-11. PMID: 29712597.found a mortality rate of 2.6%.

In the present study, esophagogastric anastomotic fistulas were observed in five cases (3.67%). Similar rates have been reported by Oninger et al.2323 Orringer MB, Stirling MC. Esophageal resection for achalasia: indications and results. Ann Thorac Surg. 1989;47(3):340-5.

The use of the whole stomach as a plasty organ facilitates preservation of the vagal trunks and innervation of the stomach. Peyre and Demeester2626 Peyre CG, Demeester TR. Vagal-sparing esophagectomy. Adv Surg. 2008;42:109-16. doi: 10.1016/j.yasu.2008.04.004.

used a gastric tube and proposed preservation of the vagal trunks and innervation of the antrum and pylorus, which resulted in a reduction of postoperative morbidity and mortality. Preservation of the vagal trunks has been shown to favor the maintenance of gastric emptying during the early and late postoperative period. In the present study, only three (2.2%) of the 136 cases with vagus nerve preservation exhibited early gastric emptying problems and none of the patients had late problems. Among the 95 cases submitted to surgery without vagus nerve preservation, eight (8.42%) had early gastric emptying problems and four (4.21%) had late problems. Similar results have been reported by Banki et al.2727 Banki F, Mason RJ, DeMeester SR, Hagen JA, Balaji NS, Crookes PF, Bremner CG, Peters JH, DeMeester TR. Vagal-sparing esophagectomy: a more physiologic alternative. Ann Surg. 2002;236(3):324-36. doi: 10.1097/01.SLA.0000027081.93085.BB.

An increase in the incidence of transient dysphonia has been described for the laparoscopic transhiatal approach (25%-66.6%)1919 Swanstrom LL, Hanson P. Laparoscopic total esophagectomy. Arch Surg. 1997;132(9):943-7. PMID: 9301605.. An increase of dysphonia in the laparoscopic transhiatal technique was also detected at our service. This increase compared to the cervicoabdominal approach (4.8%) is probably due to local manipulation of the cervical region where the esophagus is sectioned and removal of the surgical specimen, which usually has a large volume. A reduction of dysphonia in the last 30 cases (6.67%) was noted when compared to the beginning of the series (23.3%).
In the absence of stenosis of the esophagogastric anastomosis, subtotal esophagectomy completely abolishes dysphagia. By taking care of maintaining the esophagogastric anastomosis in the cervical region, an area of positive pressure, the intensity of gastroesophageal reflux and consequently moderate and severe esophagitis of the esophageal stump are reduced, especially in cases in which the pylorus is preserved and duodenogastric reflux is lower.
The secretion of pancreatic peptide was studied in 46 cases and confirmed functional preservation of the vagus nerves. This fact was also observed by Banki et al.2727 Banki F, Mason RJ, DeMeester SR, Hagen JA, Balaji NS, Crookes PF, Bremner CG, Peters JH, DeMeester TR. Vagal-sparing esophagectomy: a more physiologic alternative. Ann Surg. 2002;236(3):324-36. doi: 10.1097/01.SLA.0000027081.93085.BB.

According to Mormando et al.2929 Mormando J, Barbetta A, Molena D. Esophagectomy for benign disease. J Thorac Dis. 2018 Mar;10(3):2026-33. doi: 10.21037/jtd.2018.01.165.
https://doi.org/10.21037/jtd.2018.01.165...
, vagus nerve preservation is a good option to improve the quality of life of patients submitted to esophagectomy for the treatment of benign disorders.
Conclusion
Laparoscopic transhiatal esophagectomy is a feasible and safe technique with excellent postoperative outcomes.
