Abstract: Hiatal hernia after minimally invasive esophagectomy (MIE) is an important postoperative complication that can cause severe morbidity or even mortality among patients with esophageal cancer. Usually repair of the hiatus immediately after esophageal reconstruction is suggested to prevent such complication. However, during the Ivor Lewis MIE procedure, hiatal repair is difficult to perform due to the deep-seated location of the hiatus after the final step of esophageal reconstruction in the right chest. The current study demonstrates a method of repairing the hiatus in the Ivor Lewis MIE. This is especially useful in the resection of a massive tumor near the esophagogastric (E-G) junction, which harbors a high risk of hiatal hernia when the hiatus is left unrepaired after extensive hiatal dissection.

Esophagectomy with reconstruction for esophageal cancer is a complex procedure with a risk of potentially serious postoperative morbidity. One of these morbidities is hiatal hernia, which may result in mortality due to bowel incarceration. Post-esophagectomy hiatal hernia has been reported in the literature (1,2) with an incidence estimated to be between 0.7% and 15% (1). The incidence rate differs across studies according to the surgical methods, follow-up protocols and image diagnostic criteria used, among other factors.

During the gastric conduit preparation and esophageal reconstruction in the abdominal phase of the procedure, the hiatus is usually widened to allow gastric tube elevation through the hiatus into the mediastinum and prevent conduit obstruction. The risk of hiatal hernia can be further enhanced after completion of the laparoscopic procedure, which results in diminished postoperative tissue adhesion. In the McKeown procedure, we typically repair the widened hiatus with laparoscopic suture. However, it is difficult to repair a widened hiatus in the Ivor Lewis procedure. The first reason for this is that we cannot suture the crus muscle because the gastric conduit has not yet been pulled into the mediastinum. The second reason is that it is difficult to repair the crus muscle with thoracoscopy due to the very deep position of the hiatus and poor exposure. Thus, the crus muscle is ordinarily not repaired in our general practice with the Ivor Lewis procedure. In our own experience, there is a higher incidence of post-esophagectomy hiatal hernia in the Ivor Lewis procedure than in the McKeown procedure.

In this report, we share a surgical technique to repair the widened hiatus in the Ivor Lewis procedure. This case report is presented in accordance with the CARE Guideline.

Patient selection

We followed the NCCN (National Comprehensive Cancer Network) guideline to treat esophageal cancer. Neoadjuvant concurrent chemoradiotherapy (CCRT) was administered to patients with clinically positive lymph nodes and followed by esophagectomy.

Minimally invasive esophagectomy (MIE) has been our preferred method of esophagectomy since 2011, either transhiatal esophagectomy, the McKeown procedure, or the Ivor Lewis procedure. Transhiatal esophagectomy is currently excluded from our clinical practice because of the difficulty of performing mediastinal lymph node dissection. For patients with upper or middle third esophageal cancer, the McKeown procedure is suitable for them. Since the two-stage Ivor Lewis procedure was first introduced in 1946, it has been the operation of choice for esophageal cancer involving the lower-third esophagus or esophagogastric (E-G) junction (3). In our hospital, we generally perform total thoracoscopic and laparoscopic Ivor Lewis esophagectomy. Sometimes we have even tried single-portal esophagectomy, gastric conduit mobilization and intrathoracic anastomosis with circular stapler.

The case we present in this report is a 34-year-old male who had no underlying disease. He presented with dysphagia and worsening of the symptoms progressed rapidly. The imaging study showed an E-G junction tumor approximately 5 cm in maximal diameter. Endoscopic ultrasound also revealed a tumor above the E-G junction that had almost completely obstructed the esophageal lumen. Adenocarcinoma was reported in the pathological examination. Positron emission tomography showed no distant metastasis. No adjacent organ invasion was noted in bronchoscopy and computed tomography scan. This patient was diagnosed with cT3N1M0, stage III esophageal adenocarcinoma.

Pre-operative preparation

After the patient received neoadjuvant CCRT, the tumor shrank and the post-CCRT clinical stage was diagnosed as ycT3N0M0. An Ivor Lewis procedure was performed one month after completion of neoadjuvant CCRT.

The patient was placed under intubated general anesthesia. The anesthesiologist used a single-lumen endotracheal tube with an enclosed bronchial blocker to establish one-lung ventilation for prevention of lung hindrance to the surgical field. The MIE Ivor Lewis procedure consisted of two stages; the abdominal stage followed by the thoracic stage. In the abdominal stage, the patient was set in the supine position with legs together; in the thoracic stage, the patient was set in the standard left lateral decubitus position with oblique stretching.

Abdominal stage

A single periumbilical incision was made, and a wound protector was applied. We performed liver tenting to secure a better surgical field (5). We then divided the gastrocolic ligament and short gastric vessels and adequately exposed the crus muscle. We separated the attachments between the stomach and pancreas, then raised the stomach so that the left gastric artery and vein could be divided. The lymph nodes along the left gastric artery (station 7, Japan Esophageal Society) were dissected and removed. We used a linear stapler to form a gastric conduit. A feeding jejunostomy was also performed on the jejunum 40 cm from the Treitz ligament for postoperative nutrition support (6,7).

Finally, we widened the hiatus to let the gastric tube pass into the mediastinum without resistance (Figure 2A). Then we sutured the crus muscle with the Endo Stitch Suturing Device without a tie (Figure 2B). We retained approximately 40 cm of the suture string and made an anchoring suture on the tip of the gastric conduit (Figure 2C) This allowed us to reach the string sutured on the crus muscle when we pulled the gastric conduit into the thoracic cavity in the next stage.

(A) The hiatus was widened for gastric conduit elevation into the thoracic cavity; (B) the crus muscle was sutured with Endo-stitch string (without tying); (C) the other end of Endo-stitch was anchored on the tip of the gastric conduit. E-G, esophagogastric.

Thoracic stage

After completion of the first stage, we set the patient in the left decubitus position. A single thoracoscopic working port was made over the 7th intercostal space along the middle axillary line. For better surgical exposure, the azygos vein was sacrificed and several retention stitches were anchored along the border of the esophagus (5). Then we dissected the esophagus extensively through the crevice to the lower mediastinum. Mediastinal lymph nodes were also dissected (station 105, 106 and 107, Japan Esophageal Society). The esophagus was divided at the level of the azygos vein (about 7 cm proximal to the tumor) with a 60 mm linear stapler. We pulled the stomach and the gastric conduit into the thoracic cavity so that the previously sutured string on the crus could be reached (Figure 3A). We performed anastomosis between the remaining esophageal stump and the gastric conduit with a 21mm circular stapler. A running barbed V-loc suture was performed for anastomosis reinforcement.

Once we reached the suture string that we sutured on the crus muscle in the abdominal stage, we were able to expose the hiatal defect clearly by stretching the string (Figure 3B). With good exposure, we made another suture on the crus muscle for reinforcement and tied it with a node pusher (Figure 3C).

Role of the team members

Like other surgeries, MIE requires close, cooperative teamwork to facilitate efficiency and safety in the operating room.

The surgical team consisted of:

  • Attending surgeon: Jang-Ming Lee, MD, PhD;
  • Assistant surgeon: Xu-Heng Chiang, MD;
  • Anesthesiologist and nurse anesthetist;
  • Scrub nurse and circulating nurse.

The attending surgeon should be the leader and instruct other team members to secure good communication and coordination during the surgery.

The anesthesiologist controls cardiopulmonary stability during the operation.

Postoperative management

The patient was extubated in the operating room and then transferred to the surgical intensive care unit for post-operative care. On postoperative day two, he was transferred to the normal surgical ward. Nutrition was supported via jejunostomy feeding tube, and the patient was able to drink water perorally. The patient was discharged from the hospital on postoperative day nine. There was no surgical complication or other adverse event during the hospital stay. There was no hiatal hernia on the chest plain film 3 months after operation.

Discussion and conclusions

The introduction of MIE has significantly improved the outcome of esophagectomy, with a decrease in blood loss, respiratory distress, and postoperative pain, as well as shorter hospital stay compared to conventional open esophagectomy (7,8). However, incidence of post-MIE hiatal hernia is reported to be higher than in traditional esophagectomy (4.5% vs. 1.0%) (9). Thus, to prevent hiatal hernia has become an important issue with the prevalence of MIE. Especially for the Ivor Lewis procedure, effective repair of the crus muscle was highly problematic in the past. Although single portal MIE for the Ivor Lewis procedure was effective and safe in preliminary reports, there was no adequate technique to reduce frequency of postoperative hiatal hernia (10). With similar principles and procedures, it is also feasible to repair hiatal defects in the Ivor Lewis procedures performed by multi-portal MIE or open esophagectomy.
