Backgrounds/Aims: Extra hepatic portal venous obstruction (EHPVO) is the most common cause of portal hypertension in Indian children. While endoscopy is the primary modality of management, a subset of patients require surgery. This study aims to report the short- and long-term outcomes of EHPVO patients managed surgically. Methods: All the patients with EHPVO who underwent surgery between August 2007 and December 2021 were retrospectively reviewed. Postoperative complications were classified after Clavien-Dindo. Binary logistic regression in Wald methodology was used to determine the predictive factors responsible for unfavourable outcome. Results: Total of 202 patients with EHPVO were operated. Mean age of patients was 20.30 ± 9.96 years, and duration of illness, 90.05 ± 75.13 months. Most common indication for surgery was portal biliopathy (n = 59, 29.2%), followed by bleeding (n = 50, 24.8%). Total of 166 patients (82.2%) had shunt procedure. Splenectomy with esophagogastric devascularization was the second most common surgery (n = 20, 9.9%). Nine major postoperative complications (Clavien-Dindo > 3) were observed in 8 patients (4.0%), including 1 (0.5%) operative death. After a median follow-up of 56 months (15-156 months), 166 patients (82.2%) had favourable outcome. In multivariate analysis, associated splenic artery aneurysm (p = 0.007), isolated gastric varices (p = 0.004), preoperative endoscopic retrograde cholangiography and stenting (p = 0.015), and shunt occlusion (p < 0.001) were independent predictors of unfavourable long-term outcome. Conclusions: Surgery in EHPVO is safe, affords excellent short- and long-term outcome in patients with symptomatic EHPVO, and may be considered for secondary prophylaxis.

Background: The aim of this study is to investigate the clinical characteristics and management of intrathoracic bronchogenic cysts. Materials and Methods: Twenty-four (n=24) patients with intrathoracic bronchogenic cysts were treated surgically between August 1990 and December 2009 at our institution. Patients were divided into two groups by bronchogenic cyst location: mediastinal or intrapulmonary. Symptoms at diagnosis, radiologic findings, locations, surgical methods, pathological findings, and surgical outcomes were investigated retrospectively from consecutive patient medical records. Results: There were 12 females (50.0%). The mean age was 26.8 (range, 5 to 64) years. The mean follow-up period was 27.3 (range, 1 to 121) months. There were 15 (62.5%) mediastinal and 9 (37.5%) intrapulmonary bronchogenic cysts. Symptoms occurred in 8 patients with mediastinal bronchogenic cysts (53.3%) and 5 patients with intrapulmonary bronchogenic cysts (55.6%) (p=1.000). On computed tomography (CT), 7 patients (46.7%) showed homogenous solid masses in mediastinal bronchogenic cysts and five (55.6%) patients exhibited heterogeneous cystic masses with air-fluid levels in intrapulmonary bronchogenic cystic masses. Open thoracotomy was performed in 17 (70.8%) patients, and video-assisted thoracic surgery was performed in 7 (29.2%) patients. On pathological findings, there were 16 (66.7%) complicated cysts, and in 13 symptomatic patients, 11 (84.6%) patients had complicated cysts. There was no operative death in this study. During the follow-up period, no recurrence was detected. Conclusion: Intrathoracic bronchogenic cysts have a wide variety of clinical characteristics and radiologic findings. Even though some patients do not experience symptoms and signs caused by bronchogenic cysts, serious symptoms and complications may develop with the passage of time.

Purpose: The aims of this study were to make serial comparisons of the quality of life (QoL) between patients who underwent total gastrectomy and those who underwent distal subtotal gastrectomy for gastric cancer and to identify the affected scales with consistency. Materials and Methods: QoL data of 275 patients who were admitted for surgery between September 2008 and June 2011 and who underwent subtotal gastrectomy or total gastrectomy were obtained preoperatively and postoperatively at 3, 6, 9, 12, 18, and 24 months. The Korean versions of the European Organization for Research and Treatment (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and the gastric cancer specific module, the EORTC QLQ-STO22, were used to assess QoL. Results: QoL, as assessed by the global health status/QoL and physical functioning, revealed a brief divergence with worse QoL in the total gastrectomy group 3 months postoperatively, followed by rapid convergence. QoL related to restrictive symptoms (nausea/vomiting, dysphagia, reflux, and eating restrictions) and dry mouth was consistently worse in the total gastrectomy group during the first 2 postoperative years. Conclusions: The general QoL of patients after gastrectomy is highly congruent with subjective physical functioning, and the differences between patients who undergo total gastrectomy and subtotal gastrectomy are no longer valid several months after surgery. In order to further reduce the differences in QoL between patients who underwent total gastrectomy and subtotal gastrectomy, definitive preoperative informing, followed by postoperative symptomatic management, of restrictive symptoms in total gastrectomy patients is the most rational approach.

Objectives: Despite of high prevalence of tuberculosis in Korea, thyroid tuberculosis is very rare and only a few records are available. This study was carried out to evaluate the clinicopathologic characteristics of thyroid tuberculosis and to find out optimal therapeutic strategies for these lesions. Materials & Methods: From Jan. 1986 to July. 2000, of 5,493 patients who were underwent thyroidectomy, only 8(0.14%) had discovered to have thyroid tuberculosis. The medical records of them were analyzed retrospectively. Results: There were one man and seven women with a mean age of 40.3 years. Only one had tuberculosis sequalae on chest X-ray and two had past history of tuberculous lymphadenitis. However, none of them had symptomatic pulmonary tuberculosis. Most frequent symptom was palpable neck mass. The preoperative U/S, CT and FNAB failed to diagnose thyroid tuberculosis. The pathologic reports were chronic granulomatous thyroiditis with caseous necrosis in all the cases and AFB stain was positve in 5 cases. All cases were successfully treated by surgical resection and anti-Tbc. medications. Conclusions: The incidence of thyroid tuberculosis was extremely low and most of them have been presented as a palpable neck mass especially in relatively young-aged female patients. Although any diagnosis for thyroid tuberculosis prior to microscopical study of tissue removed at operation was not yielded, the preoperative diagnostic workups will be available with experience. Surgical resection and anti- Tbc medication would be the choice in the management of thyroid tuberculosis.

Feline hemotropic mycoplasmosis (hemoplasmosis) is an infection of the red blood cells caused by the Mycoplasma haemofelis (Mhf), Candidatus Mycoplasma haemominutum (CMhm), and Candidatus Mycoplasma turicensis (CMt). The existence of Mhf, CMhm, and CMt has been demonstrated in feral cats in Korea using molecular methods, but no clinical cases have yet been reported. This study reports 2 clinical cases of hemotropic mycoplasmosis caused by CMhm and CMt in 2 anemic cats. The first case was a client-owned intact female domestic shorthair cat that presented with fever, pale mucous membranes, and normocytic normochromic non-regenerative anemia. Prior to referral, an immunosuppressive prednisolone dose was administered at the local veterinary clinic for 1 month. The cat was diagnosed with high-grade alimentary lymphoma. Organisms were found on the surface of the red blood cells on blood smear examination. The second case was of a rescued cat that presented with dehydration and fever. The cat had normocytic normochromic non-regenerative anemia. Necropsy revealed concurrent feline infectious peritonitis. Polymerase chain reaction assay targeting 16S rRNA revealed CMhm infection in case 1 and dual infection of CMhm and CMt in case 2. Normocytic normochromic non-regenerative anemia was observed in both cats before and during the management of the systemic inflammation. This is the first clinical case report in Korea to demonstrate CMhm and CMt infections in symptomatic cats.

Even after testing negative for COVID-19, some patients continue to struggle with a variety of symptoms such as fatigue, shortness of breath, gastrointestinal problems and neurological problems. The World Health Organization (WHO) defined long COVID (Post COVID-19 conditions) as "A disease occurs in individuals with a history of probable or confirmed SARS-CoV-2 infection, usually 3 months from the onset of COVID-19 with symptoms that last for at least 2 months, that cannot be explained by an alternative diagnosis." As a possible pathological mechanism of long COVID, three hypotheses are proposed: the persistence of the infectious state due to the residual virus, the persistent inflammatory response, and the autoimmune response. The main symptoms of long COVID are shortness of breath (dyspnea), abdominal pain and dyspepsia, fatigue, cognitive problems (brain fog), anosmia and dysgeusia, and chest pain, palpitations and tachycardia. In the Chinese guidelines, COVID-19 patients were divided into mild, moderate, severe, and recovery, and prescriptions with effective therapeutic effects were summarized to encourage combined treatment of chinese and western medicine. Globally, only symptomatic therapy is recommended for long COVID, but a specific treatment has not yet been proposed. Recently, morbidity code for post COVID-19 conditions was created, and it is planned to announce guidelines for long COVID treatment and management in the first half of 2023. In line with this trend, the Korean medical community needs to make efforts to prepare treatment guidelines for patients with long COVID.

증상이 있는 양성 갑상선결절의 비수술적 치료법인 고주파 절제술은 결절 조직을 열로 소작하여 부피를 감소시키고, 이로 인해 증상의 완화와 외견상 문제를 해결한다. 고주파절제술의 적응증은 2회 이상 세포/조직검사로 양성이 확인된 결절에서 의학적 치료가 필요한 주관적 또는 외견상의 임상증상이 있는 경우이다. 고주파 절제술은 1년의 단기 추적에서 매우 양호한 성적을 보이지만 3년 이상의 장기 추적에서는 20%-30% 결절의 재성장이 발생한다. 따라서 장기 추적을 전제로 하는 고주파절제술 후 환자 관리에서는 재성장을 관리하는 것이 핵심이다. 재성장은 치료 전 결절부피가 큰 경우, 혈관성이 높거나 증가하는 경우 잘 발생하며, 최근에는 수분 박리(hydrodissection), 동맥우선소작법, 정맥소작법등 새로운 기술들이 도입되어 재성장을 억제하고 있다. 또한 적절한 기준을 적용하여 재치료를 하는 것이 재성장을 관리하고 치료 효과를 오래 지속시키는데 중요하다. 고주파 절제술은 근본적으로 수술의 대안이므로 일시적 효과를 거두는 것이 아니라 영구적으로 수술을 회피하도록 하는 것이 궁극적인 목표이다.
