Foreign body ingestion is a frequent event in the pediatric age group, but the incidence of foreign bodies in the appendix is very low. The authors report a case of ingested foreign body trapped in the appendix in a 7-year-old girl. The foreign body was successfully treated by laparoscopic appendectomy under fluoroscopic guidance.

Recently we have experienced an about 15cm long foreign body lodged at trachea in the adult patient, it was a toothbrush bar of which the head had been removed by patient himself. Its tip was shown above vocal cord on videogastroscope, so we removed the toothbrush bar by using the foreign body forcep. So we report it with review of literature.

The lodgement of foreign material in the larynx is potentially life thereatening as complete obstruction of this region does not leave the individual with a viable airway. In the literature review, laryngeal foreign bodies accounted for about $3\%$ of the whole foreign bodies in the air passage. This report describes a rare case of laryngeal obstruction by subglottic foreign body(tooth) occurred during tooth extraction, in which repeated Heimlich maneuver failed to expel the foreign body and aggravated airway obstruction.

Laryngeal foreign bodies are not common among the foreign bodies of aerodigestive tract. It is relatively easy to diagnose in acute phase of entry because of a readily\ulcorner available history of intake, and signs or symptoms referable to the foreign body in the highly sensitive air passage. However, on occasion, sudden death by respiratory failure occurs due to complete obstruction of airway. Therefore, it is common and safe to remove the laryngeal foreign bodies by suspension laryngoscope under general anesthesia after tracheostomy. Recently, the authors experienced a case of metallic foreign body in larynx penetrating neck, which was removed by suspension laryngoscope under general anesthesia without any life threatening complication.

Aspiration of foreign bodies into the tracheobronchial tree is unusual in adults and it may result in Proximal airway obstruction and acute life-threatening asphyxia. It can be diagnosed by history of aspiration or visualizing the foreign body by chest roentgenogram or bronchoscopy. But it is rarely considered in adults with subacute or chronic respiratory symptoms without a definite history which suggests an aspiration. A 70-year-old woman was admitted to the hospital due to productive cough for two months and dyspnea which aggravated since the day before admission. Chest X-ray showed Pneumonic infiltration on left upper lobe and right lower lobe. Despite several days of conventional therapy, the patient complained of severe dyspnea and wheezing. We performed chest CT to rule out endobronchial stenosis, and it revealed the narrowing of left main stem bronchus compatible with endobronchial tuberculosis. Fiberoptic bronchoscopy for confirmation disclosed a $3.2{\times}0.7{\times}0.2$cm sized foreign body located longitudinally at the left main stem bronchus. We removed it with alligator forcep and it proved In be a piece of artificial denture. The patient remembered losing it while severe coughing on the day before admission. The microscopic examination of bronchial washing fluid revealed numerous acid fast bacilli. After removal of the foreign body, the patient showed marked improvement in symptom and pulmonary function test. Here we report a case of Pulmonary aspiration of foreign body which is confused with endobronchial tuberculosis with a review of the literature.

Esophageal foreign body is common condition for visit emergency room, and most of them were successfully removed with endoscopy. However, in case of esophageal foreign body impaction, it can be difficult to localize the foreign body. We report a 29-year old man with esophageal foreign body impaction. We successfully localized and removed the esophageal submucosal foreign body using rigid endoscopy under C-arm guidance, avoiding more invasive procedure. The patient was followed up without any complication.

We report the case of a seven-year-old boy with an ingested foreign body, which was retained within the appendix for a known duration of ten months, ultimately requiring appendectomy. The ingested foreign body was incidentally discovered by abdominal x-ray at an emergency room visit for constipation. Despite four bowel cleanouts, subsequent x-rays showed persistence of the foreign body in the right lower quadrant. While the patient did not have signs or symptoms of acute appendicitis, laparoscopic appendectomy was performed due to the risk of this foreign body causing appendicitis in the future. A small metallic object was found within the appendix upon removal. This case highlights the unique challenge presented by foreign body ingestions in non-verbal or developmentally challenged children and the importance of further diagnostic workup when concerns arise for potential retained foreign bodies.

A thirty-month-old male Moluccan Cockatoo (Cacatua moluccansis) with mild anorexia was referred. Through physical examination, fireign body was palpated at the crop region. Radiopaque, lineal foreign body was visualized on the lateral radiographs of the thoracic esophageal region. The patient was definitively diagnosed esophageal foreign body which is ingested feeding tube. The foreign body removal was undertaken using a flexible endoscope and a grasping forcep without any other complications. This case report demonstrated that successful esophageal foreign body removal with endoscopy in birds.

In this paper, we propose an automaticdetection method of foreign bodies through template matching in industrial CT volume data. Our method is composed of three main steps. First,Indown-sampling data, the product region is separated from background after noise reduction and initial foreign-body candidates are extracted using mean and standard deviation of the product region. Then foreign-body candidates are extracted using K-means clustering. Second, the foreign body with different intensity of product region is detected using template matching. At this time, the template matching is performed by evaluating SSD orjoint entropy according to the size of detected foreign-body candidates. Third, to improve thedetection rate of foreign body in original volume data, final foreign bodiesare detected using percolation method. For the performance evaluation of our method, industrial CT volume data and simulation data are used. Then visual inspection and accuracy assessment are performed and processing time is measured. For accuracy assessment, density-based detection method is used as comparative method and Dice's coefficient is measured.

Among lesions in the larynx, laryngeal contact granuloma due to persistent tissue irritation can typically be attributed to endotracheal intubation, vocal abuse, or gastro-esophageal reflux disease. Treatment typically includes voice therapy, lifestyle changes and use of anti-reflux medication. Microsurgical removal is only indicated in cases of severe dyspnea due to mass size. Foreign body granuloma is a response of to any foreign material in the tissue. Foreign body granulomas are sometimes misdiagnosed as soft tissue tumors when the causative foreign body is not initially found. Delayed treatment of these foreign bodies may cause complications. We present a case of larynx granuloma due to impacted foreign body, probably fish bone, in the larynx that mimicked contact granuloma. We initially used anti-reflux medication, but to no avail. The laryngeal mass, observed through laryngoscopy, showed no improvement and therefore necessitated a proper pathologic diagnosis. We were able to successfully treat it via trans-oral laser CO2 microsurgery before any complications developed.
