Surgical repair of esophageal perforation is a challenging procedure with a high risk of secondary complications, such as early esophageal leakage and late esophageal stricture, which can significantly reduce the patient\'s quality of life. A 34-year-old man underwent anterior cervical corpectomy decompression and fusion. On the ninth day post-operation, the patient developed fever and neck swelling. A computed tomography scan of the neck showed multiple subcutaneous pneumatosis. An esophageal perforation of approximately 1.5 cm in diameter was identified by esophagoscopy. During the operation, the fistula was first located using an esophagoscope. The distal end of the esophagoscope was then placed into the stomach to support the damaged segment of the esophagus. The esophageal mucosa was sutured under the microscope, and the perforation was successfully repaired. Postoperatively, the patient\'s body temperature decreased, and the infection indexes gradually returned to normal. Three months after the operation, the esophagoscopic review showed complete healing of the perforation. Esophagoscopy plays an important role in diagnosing and repairing esophageal perforations. The esophagoscope provides direct visualization of the perforation during diagnosis and detects smaller and not yet fully penetrated esophageal injuries. During the repair process, the esophagoscope immobilizes the esophagus, prevents its movement and facilitates suturing, maintains proper dilatation of the esophagus, provides space for suturing, and prevents esophageal stricture.

One of the complications of esophageal endoscopic submucosal dissection (ESD) is postoperative stricture formation. Stenosis formation is associated with inflammation and fibrosis in the healing process. We hypothesized that the degree of thermal damage caused by the device is related to stricture formation. We aimed to reveal the relationship between thermal damage and setting value of the device. We energized a resected porcine esophagus using the ESD device (Flush Knife 1.5). We performed 10 energization points for 1 s, 3 s, and 5 s at four setting values of the device. We measured the amount of current flowing to the conducted points and the temperature and evaluated the effects of thermal damage pathologically. As results, the mean highest temperatures for 1 s were I (SWIFT Effect3 Wat20): 61.19 °C, II (SWIFT Effect3 Wat30): 77.28 °C, III (SWIFT Effect4 Wat20): 94.50 °C, and IV (SWIFT Effect4 Wat30): 94.29 °C. The mean heat denaturation areas were I: 0.84 mm2, II: 1.00 mm2, III: 1.91 mm2, and IV: 1.54 mm2. The mean highest temperature and mean heat denaturation area were significantly correlated (P < 0.001). In conclusion, Low-current ESD can suppress the actual temperature and thermal damage in the ESD wound.

A coin cell lithium battery is a common foreign body that can become lodged in the pediatric pharyngoesophageal junction. Because the voltage of such batteries is relatively high, their rapid removal is necessary to avoid mucosal necrosis. Despite being the initial choice for removal, flexible endoscopy cannot remove such foreign bodies from the esophagus. Various removal methods, including rigid esophagoscopy, should be considered for removing lithium coin cell batteries. The transcervical approach is feasible for removing esophageal foreign bodies, but it carries the risk of complications such as esophageal stenosis. Here we report a case of lithium coin battery ingestion that was successfully removed using a rigid esophagoscope. A 2-year-old girl was referred to a local doctor with cough and general fatigue. Chest X-ray and flexible endoscopy revealed a coin cell lithium battery stuck in the pharyngoesophageal junction, but it could not be removed. The foreign body was removed using Nishihata forceps through a rigid esophagoscope under general anesthesia.

BACKGROUND: Foreign body ingestion is a common emergence in gastroenterology. Foreign bodies are most likely to be embedded in the esophagus. The sharp ones may penetrate the esophageal wall and lead to serious complications.
METHODS: A 72-year-old Chinese female was admitted to our hospital with a 4-day history of retrosternal pain and a growing cough after eating fish. Chest computed tomography scan indicated that a high-density foreign body (a fish bone) penetrated through the esophageal wall and inserted into the left main bronchus. First, we used a rigid esophagoscope to explore the esophagus under general anesthesia. However, the foreign body was invisible in the side of the esophagus. Then, the fiberoptic bronchoscopy was performed. We divided the fish bone, which traversed the left main bronchus, into two segments under holmium laser and removed the foreign body successfully. The operation time was short and there were no complications. The patient was discharged 1 week postoperatively and was symptom free even under a liquid diet.
CONCLUSIONS: There are several challenges in the management of this rare condition. We applied the technique of interventional bronchoscopy to the management of esophageal foreign body flexibly in an emergency. A surgery was avoided, which was more invasive and costly.

Intraoperative localization within the thoracic spine in the prone position may be particularly difficult on account of absence of common landmarks such as the sacrum or the C2 vertebra, thus increasing the potential for wrong-level surgery that may lead to patient morbidity and potential litigation. Some current localization methods involve implantation of markers that are invasive and serve to add to procedural expense while yet still failing to entirely eliminate errors. We describe a novel, non-invasive, and inexpensive technique for intraoperative localization of the thoracic spine in the prone position using an esophageal temperature probe. Following patient positioning, anteroposterior fluoroscopy is used to localize the radiopaque tip of the esophageal probe relative to the thoracic spine. After determining the probe tip\'s location, it becomes the counting reference for all subsequent intraoperative fluoroscopic localizations during surgery. As the probe tip is generally visible in the same fluoroscopic image as the surgical level, error from parallax created when moving the fluoroscopy machine from an anatomic landmark either above or below is avoided and a shorter fluoroscopy time is needed. Use of an esophageal temperature probe as a landmark in localizing spinal level may serve as a reliable and It offers a safe, reliable, and inexpensive technique for proper localization of thoracic spine levels.

Sword swallowing is an ancient skill that was developed by the fakirs of India and slowly permeated the globe leading up to the late 19th century. Its rise as a popular circus act in Europe coincided with the surge of inventive young minds in the medical community. This crossroad brought about a working relationship between Dr Adolf Kussmaul and a sword swallower named the \"Iron Henry.\" Together, they developed a scope that could be passed through the esophagus for evaluation of disease states from the upper aerodigestive tract all the way to the antrum of the stomach. The unique abilities refined by years of sword swallowing were vital in the work to develop and perform the first successful esophagoscopy and then disseminate the technology. This story should not be forgotten and can give insight into how historical practices and modern invention can come together to great effect.

Create a competency-based assessment tool for pediatric esophagoscopy with foreign body removal.
Blinded modified Delphi consensus process.
Tertiary care center.
A list of 25 potential items was sent via the Research Electronic Data Capture database to 66 expert surgeons who perform pediatric esophagoscopy. In the first round, items were rated as \"keep\" or \"remove\" and comments were incorporated. In the second round, experts rated the importance of each item on a seven-point Likert scale. Consensus was determined with a goal of 7 to 25 final items.
The response rate was 38/64 (59.4%) in the first round and returned questionnaires were 100% complete. Experts wanted to \"keep\" all items and 172 comments were incorporated. Twenty-four task-specific and 7 previously-validated global rating items were distributed in the second round, and the response rate was 53/64 (82.8%) with questionnaires returned 97.5% complete. Of the task-specific items, 9 reached consensus, 7 were near consensus, and 8 did not achieve consensus. For global rating items that were previously validated, 6 reached consensus and 1 was near consensus.
It is possible to reach consensus about the important steps involved in rigid esophagoscopy with foreign body removal using a modified Delphi consensus technique. These items can now be considered when evaluating trainees during this procedure. This tool may allow trainees to focus on important steps of the procedure and help training programs standardize how trainees are evaluated.

BACKGROUND: Rigid oesophagoscopy is a widely used therapeutic and diagnostic procedure. Smooth friction-free insertion of the rigid scope is important to prevent oral and oesophageal mucosal damage, as such damage can cause delays in oral intake or more serious complications such as perforation. Protection appliances such as gum guards are useful adjuncts to cushion the teeth in rigid oesophagoscopy; however, there are no specific adjuncts for the edentulous patient.
METHODS: In order to investigate different adjuncts, the force required to pull a standard adult rigid oesophagoscope from a metal clamp whilst enclosed in dry gauze, wet gauze, a gum guard or sleek on gauze was recorded, and a prospective audit of post-procedural trauma was performed.
CONCLUSIONS: Less force was required to create movement of the scope against sleek on gauze, with a lower rate of oral trauma (8 per cent) compared to that reported in the literature. Sleek on gauze is recommended for the edentulous patient.
