Transhiatal esophagectomy was planned for adenocarcinoma of the lower end of esophagus. The approach would be in the following order:
**Core Concept**
Transhiatal esophagectomy is a surgical procedure for esophageal cancer that involves removing the esophagus through an incision in the abdomen and another incision in the neck, without opening the chest. This approach is chosen for its lower morbidity and mortality rates compared to traditional transthoracic esophagectomy.
**Why the Correct Answer is Right**
The correct approach for transhiatal esophagectomy involves the following steps:
1. Abdominal incision: The stomach is mobilized and the esophagus is divided at the upper level of the tumor.
2. Thoracic esophagus is dissected from the surrounding tissues and the esophagus is pulled up into the neck.
3. Cervical incision: The esophagus is removed through the cervical incision, and the gastric conduit is brought up and anastomosed to the remaining esophagus.
Dissection of the thoracic esophagus is crucial to avoid injury to the recurrent laryngeal nerves and to minimize the risk of respiratory complications.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not specify the order of dissection in the abdominal and cervical regions.
* **Option B:** This option is incorrect because it may involve opening the chest, which is not a characteristic of the transhiatal approach.
* **Option C:** This option is incorrect because it does not correctly describe the order of dissection and removal of the esophagus.
**Clinical Pearl / High-Yield Fact**
In transhiatal esophagectomy, careful dissection of the thoracic esophagus is essential to avoid injury to the recurrent laryngeal nerves, which can lead to vocal cord paralysis and respiratory complications.
**Correct Answer: C. Abdominal incision, thoracic esophagus is dissected and pulled up into the neck, cervical incision.**
