**Core Concept**
The treatment of choice for perforation of the cervical esophagus involves addressing the immediate risk of mediastinitis and sepsis, while also considering the need for definitive repair of the esophageal defect. This requires a multidisciplinary approach involving surgery, endoscopy, and intensive care.

**Why the Correct Answer is Right**
The correct answer is surgical repair, typically involving a cervical esophagostomy and drainage of the infected mediastinal tissues. This approach allows for the control of infection, stabilization of the patient, and eventual definitive repair of the esophageal defect. The surgical team may also consider the use of a temporary esophageal stent or a jejunostomy to maintain nutritional support during the acute phase.

**Why Each Wrong Option is Incorrect**
**Option A:** Endoscopic closure with clips or stents may be used for smaller perforations, but is not the treatment of choice for a large cervical esophageal perforation. This approach may not provide adequate control of infection and may lead to further complications.
**Option B:** Conservative management with antibiotics and supportive care is not sufficient for a perforation of the cervical esophagus, as it does not address the underlying cause of the injury and may lead to severe complications.
**Option C:** Jejunostomy or percutaneous endoscopic gastrostomy (PEG) tube placement may be used for nutritional support, but is not the primary treatment for a cervical esophageal perforation.

**Clinical Pearl / High-Yield Fact**
In cases of suspected esophageal perforation, a water-soluble contrast swallow study should be performed before attempting endoscopic closure or conservative management, as it can help confirm the diagnosis and guide treatment.

**Correct Answer:** C. Surgical repair
