Unilateral vocal fold paralysis resulting in glottal incompetence can cause significant morbidity attributable to impaired speech, swallowing, and ability to protect the airway. The treatment of unilateral vocal cord paralysis has a long history, marked by technical innovations and improvements. These methods typically use endoscopic injection or implants to augment the volume of the affected vocal fold. The first known treatment, reported by Brunnings in 1911, was paraffin injection. The first thyroplasty medializing the paralysed vocal cord was performed by Payr in 1915 ; here, a cartilage door-flap was created from the thyroid ala to obtain better voice quality. In the 1970s, Isshiki systematized and developed the use of the external medialization by Payr. Later he modified his original technique, and achieved safer and better results. Many other methods were introduced for external medialization during the 1980s and 1990s. There has been couple of materials using for medialization laryngoplasty: silicone bloc, cartilage, goretex (polytetrafluoroethylene), titanium, etc. Among them, silicone bloc is the most popularly used material. Type I thyroplasty in combination with arytenoid adduction is a proven technique for medialization of the paralysed vocal fold. In this paper, personal experience for using silicone bloc type I thyroplasty : decision making and practical points, long-term results and complication of the procedure will be discussed.

Dieulafoy lesions, vascular anomalies typically found along the gastrointestinal tract, have been viewed as rare and obscure causes of sudden intestinal bleeding, especially in pediatric patients. Since their discovery in the late 19th century, the reported incidence has increased. This is due to an increased awareness of, and knowledge about, their presentation and to advanced endoscopic diagnosis and therapy. Our patient was a three-year-old male, without a complex medical history. He presented to the emergency department with acute hematemesis with blood clots and acute anemia requiring blood transfusion. Endoscopy revealed four isolated Dieulafoy lesions along the lesser curvature of the stomach, which were treated with an epinephrine injection. The Dieulafoy lesion, although thought to be rare, should be considered when investigating an acute gastrointestinal bleed. These lesions have been successfully treated endoscopically. Appropriate anticipation and preparation for diagnosis and therapy can lead to optimal outcomes for the pediatric patient.

We experienced a case of induction of general anesthesia without using neuromuscular blocking agents (NMBAs) in a 40-year-old woman with a history of anaphylaxis immediately after the administration of anesthetics lidocaine, propofol, and rocuronium to perform endoscopic sinus surgery 2 years before. The skin test showed a positive reaction to rocuronium and cis-atracurium. We induced general anesthesia without using NMBAs after inducing airway anesthesia with lidocaine (transtracheal injection and superior laryngeal nerve block). Deep general anesthesia was maintained with end-tidal 4 vol% sevoflurane. Hypotension was treated with phenylephrine infusion. The operation condition was excellent, and patient recovered without complications after surgery. Airway anesthesia with local anesthetics may be helpful when we cannot use NMBAs for any reason, including hypersensitivity to NMBA and surgery that needs neuromuscular monitoring.

Trousseau's syndrome is an unexplained thrombotic event that precedes the diagnosis of an occult visceral malignancy or appears concomitantly with the tumor. Upper extremity deep vein thrombosis is prevalent in patients with a central venous catheter. Furthermore, a peripheral intravenous injection may cause upper extremity deep vein thrombosis as well. However, a deep vein thrombosis has not been reported in the form of Trousseau's syndrome with a catastrophic clinical course triggered by a single peripheral intravenous injection. A 48-year-old man presented with a swollen left arm on which he was given intravenous fluid at a local clinic due to flu symptoms. Contrast computed tomgraphy scans showed thromboses from the left distal brachial to the innominate vein. The patient developed multiple cerebral infarctions despite anticoagulation treatment. He was diagnosed with stomach cancer by endoscopic biopsy to evaluate melena and had a persistently positive lupus anticoagulant. After recurrent and multiple thromboembolic events occurred with treatment, he died on day 20.

Objective: To observe and compare the effects of multi-patch biopsy under conventional white light imaging endoscopy (C-WLI) and precise targeted biopsy under magnifying narrow-band imaging endoscopy (M-NBI) on the endoscopic submucosal dissection (ESD) of early gastric cancers and intraepithelial neoplasias. Methods: According to the way of selecting biopsy specimens, patients were divided into C-WLI and M-NBI groups, 20 cases. The ESD operations of the 2 groups were compared quantitively. Results: The mean frequency of biopsy in M-NBI group was ($1.00{\pm}0.00$), obviously lower than in the C-WLI group ($4.78{\pm}1.02$) (P<0.01).The average total number of selected biopsy specimens was also fewer ($1.45{\pm}0.12$ and $7.82{\pm}2.22$, respectively, P<0.01). There was no significant difference in the time of determining excision extension, marking time and the time of specimen excision of 2 groups during the ESD (P>0.05), whereas submucosal injection time, mucosal dissection time, stopping bleeding time, wound processing time in the M-NBI group were significantly shorter than in the C-WLI group (P<0.01). Conclusion: Precise targeted biopsy under M-NBI can obviously shorten the time of ESD operation, with small quantity of tissues but high pathological positive rate.

Background: Percutaneous transforaminal endoscopic discectomy (PTED) has been widely used in the treatment of lumbar degenerative diseases. Epidural injection of steroids can reduce the incidence and duration of postoperative pain in a short period of time. Although steroids are widely believed to reduce the effect of surgical trauma, the observation indicators are not uniform, especially the long-term effects, so the problem remains controversial. Therefore, the purpose of this paper was to evaluate the efficacy of epidural steroids following PTED. Methods: We searched PubMed, Embase, and the Cochrane Database from 1980 to June 2021 to identify randomized and non-randomized controlled trials comparing epidural steroids and saline alone following PTED. The primary outcomes included postoperative pain at least 6 months as assessed using a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). The secondary outcomes included length of hospital stay and the time of return to work. Results: A total of 451 patients were included in three randomized and two non-randomized controlled trials. The primary outcomes, including VAS and ODI scores, did not differ significantly between epidural steroids following PTED and saline alone. There were no significant intergroup differences in length of hospital stay. Epidural steroids were shown to be superior in terms of the time to return to work (P < 0.001). Conclusions: Intraoperative epidural steroids did not provide significant benefits, leg pain control, improvement in ODI scores, and length of stay in the hospital, but it can enable the patient to return to work faster.

담관 결석은 동통뿐만 아니라 황달이나 담도염 또는 췌장염 등을 유발할 수 있다. 결석에 대한 내시경적 제거가 실패할 경우 체외충격파쇄석술이 요구될 수 있는데, 이 논문은 담관 결석환자에 대한 체외충격파쇄석술 적용에 있어 보다 더 적절한 선택 기준을 정하는데 도움을 주기 위함이다. 총담관 결석 환자 중 기계적 쇄석술을 포함한 내시경적 제거에 실패한 46명이 체외충격파쇄석술을 받았다. 46명 모두 체외충격파쇄석술 전에 내시경적 유두괄약근 절개술을 받았으며, 경비담도배액관의 삽입이 이루어 졌다. 사용된 쇄석기는 초음파 유도하에 결석을 포착하는 시스템으로 spark-gap type이였다. 쇄석 후 추가적인 내시경적 제거술이 이루어 졌으며, 결석이 완전 제거된 경우는 89.1%(41/46)였으며, 자연 배출된 경우는 6.5%였다. 쇄석 후 결석제거율은 결석의 수(단일: 82.8%, 둘-셋: 100%, 넷 이상: 100%)와 크기(33 mm 미만: 92.9%, 33 mm 이상: 83.3%)에서는 큰 차이가 없었으나, 결석들의 장축 길이 합과 결석이 위치하지 않는 부분의 총담관 길이 합을 비교하였을 때 완전 제거된 경우와 그렇지 않은 경우의 비가 1:1.4와 1:1.1, 그리고 가장 큰 결석의 직경과 결석하방의 총담관 직경을 비교한 경우는 그 비가 1:0.9와 1:0.4로 의미 있는 차이를 보였다. 결론적으로, 결석의 수나 크기보다는 총담관 내에 분쇄된 결석이 충분히 움직여 바스켓으로 포획될 수 있는 공간이 있을 경우에 체외충격파쇄석술 적용이 상당히 유용하나 그렇지 않은 경우는 경피적 담도경을 이용한 제거가 유용할 것으로 보인다.

In recent years the immunocompromised population has increased rapidly to include people with acquired immune deficiency syndrome (AIDS), drug abusers, and transplant patients. Accordingly, the incidence of intracranial fungal infection has increased. Our institution experienced 2 cases of internal carotid artery (ICA) occlusion due to invasion of the cavernous sinus by an intracranial fungal infection. The first case was a 60-year-old man who presented with headache, eye pain, conjunctival injection, right-sided diplopia, and blurred vision. Infected tissues within the frontal and ethmoid sinuses were removed via bifrontal craniotomy and endoscopic sinus surgery through the Caldwell Luc approach. The second case was a 63-year-old woman who developed right-sided facial pain after a tooth extraction. The infection was not controlled despite continuous use of antifungal agents, resulting in death from sepsis. We believe that when intracranial fungal infection is suspected in a patient with orbital symptoms and a focal neurologic deficit, immediate angiographic investigation of possible ICA occlusion is warranted. Aggressive treatment with antifungal agents is the only way to improve prognosis.

Neurocysticercosis is the most common parasitic disease of the central nervous system in humans, caused by infection of the larval stage of the pork tapeworm, Taenia solium. However, cerebellar involvement is rarely reported. We report of a case of racemose cysticercosis in the cerebellar hemisphere. A 44-year-old man presented with headache and dizziness. Magnetic resonance imaging showed hydrocephalus and an ill-defined, multicystic cerebellar mass with hypersignal on T2-weighted images, hyposignal on T1-weighted images and rim enhancement after gadolinium injection. The patient underwent endoscopic third ventriculostomy and the cyst resection was done through a craniotomy. In surgical field, cysts were conglomerated in a dense collagen capsule that were severely adherent to surrounding cerebellar tissue, and transparent cysts contained white, milky fluid. Histological findings confirmed the diagnosis of cysticercosis. He received antiparasitic therapy with praziquantel after surgery. Racemose cysticercosis is rare in the cerebellar hemisphere but neurocysticercosis should be taken into consideration as a differential diagnosis of multiple cystic lesions in the cerebellum.

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous $H_2$ blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement. Hemostasis was achieved with endoscopic argon plasma coagulation (APC). After two sessions of APC, complete removal of the lesion was achieved. APC was a simple, safe and effective tool for hemostasis and the ablation of gastric hemangioma without significant complications.
