From 14 June 2002 to 30 June 2004, at the surgery department of the Hospital of Endocrinology had performed the endoscopic thoracic sympathectomy on 131 patients (61 males, 70 females), in ranging of age from 11 year old to 50. Thoracoscopic sympathectomy can performed easily and effectivelly in semi-Fowler posittion, turning the opposite with a single-lumen endotracheal tube. The rate of dry hand was 98.8% of patient. There was no death, there was no patient with hematothorax. There were 2 cases with complication of one side pneumothorax by adhesion but having good results after one day of drainaging closed pleuroperitoneal. After operation 40 patients were re-examined had pneumothorax in chest and back

249 patients (28 males, 221 females) undergone surgical treatment for thyroid cancer at the Hospital of Endocrinology from the 7th January 2002 to the 30th June 2004. Thyroid cancer was more likely in male than in female. The clinical signs were not usually acute and likely passed by in the early stage of this disease. The fine needle aspiration was the paraclinical method which had the most value in order to diagnose thyroid cancer before surgery. Total thyroidectomy or total thyroidectomy associated with cervical node dissection were the most common procedure in durgical treatment for thyroid cancer. Papillary carcinoma and follicular carcinoma in 94%. Complications and sequel after operation for parathyroid and laryngeal nerve were low in 249 patients undergone surgical treatmnent

From May 2003 to 30 June 2004, 173 patients including 163 females and 10 males suffering from thyroidectomy was performed safely, successfully. Surgeon must prosess good skill on open surgery as well as on endoscopic surgery. The indication of this method was a routine only in nodule goiter in one lobe, but in multinoduli goiter in two lobes and in basedow the operationc success was still limited, especially for basedow disease, it must be prepare well pior to operation. It can made the incision from the anterior wall of the chest or from armpit with more cosmetic benefits

his technique was performed on 50 patients with congenital dilatation of the bile duct including 35 females and 15 males, ranging in age from 3 months to 33 years old. Patients treated from 4/1996 to 6/1999 at the Pediatric Institute and at the Bach mai Hospital, with abdominal pain in 76%, jaundice in 58%, classic triad in 12%. The diagnosis and the indications for operation have based on the ultrasonography.The cyst flattened by bile suction and the intraoperative cholangiography was very useful for the dissection, the resection of cysts and the performance of the anastomosis. There were not particular difficulties to prepare a jejunal segment about 25 cm in length, 40-50 cm from Treitz, passing through a hole made in the transverse mesocolon and duodenum. 35 intussusception valves were made in the isolated loop of jejunum. There was no mortality. Only 1 case with infected wound and another case with the left underdiaphragmatic abscess caused by the leakage of the jejuno-jejunal anastomosis, successfully treated by the drainage of the abscess. All the patients normally discharged from the hospital

Conventional thyroidectomy requires a transverse cervical incision and a cutting of myocutaneos flaps to gain access to the thyroid. This approach leaves an undesirable scar on the anterior surface of the neck especially for young patients. Endoscopic thyroidectomy is a new minimally invasive technique that permits thyroid excision results of conventional thyroidectomy. From May 2003 to January 2005, the authors have performed 200 cases of endoscopic thyroidectomy at Surgical Department of national Hospital of Endocrinology. The indication for operation included thyroid nodule multinodules located in 1 lobe. The average of nodule size is 2.6cm (1.0-5.6cm). To access the thyroid, the authors use 2 approach: breast approach (100 cases) and auxiliary approach (100 cases) - There are 122 cases of lobectomy (61%), 78 of subtotal lobectomy (39.0%). - The mean operative time was 98.6 minutes (40-180), the mean blood loss was 8.6ml(0-100). - There is no mortality, the life-threaten complication as well as the hypocalcimia and there is not the conversion to open surgery. There is only one patient of the transient hoarseness. Conclusion: Endoscopic lobectomy of thyroid is feasible and safe for single nodule or multinodules located in the same lobe. There may be 2 approaches: anterior breast wall and auxiliary approach.

From 25 January 2002 to 11 May 2004, there were 200 patients operated at National Hospital of Endocrinology for treatment of Grave’s disease. Ratios of male/female were approximately 2/8. Most of them were in the range of age from 20 to 49 years old (81.0%). The operative indication included the euthyroid cases. The preoperative preparing by Lugol solution, prednisolon was necessary. The techniques of operation included: total thyroidectomy for 14 patients (7%), near total thyroidectomy with small amount of thyroid tissue left at the superior pole for 9 (4.5%), and with posterior wall remnant for 177 (88.5%). The total thyroidectomy was performed for patients who were accompanied with nodules, were allergic to synthesis anti-thyroid drugs, or severe ophthalmopathy. There were no mortality as well as thyroid storm and tarchycardia after operation. There were 3 cases had to be reoperated due to hemorrhage, 3 cases of transient hoarseness (1.5%), 19 cases of transient hypocalcaemia (9.5%).Only 64 patients came to hospital for reexamination at 3 months after operation. Among them, there were 58 euthyroid cases (90.7%) with FT4 in normal limit

Background: According to WHO, there are 5 million deaths from kinds of injury a year in the world, of which 875000 deaths occur in children under 18 years old. Injury leads to 40000 deaths which account for 10.7% deaths due to all other causes a year in VietNam. Objective: To show conclusions of the situation of child injury, recommendations for prevention of child injury and methods in order to enhance emergency activity in Vietnam. Subjects and method: The authors collected information about all patients who had emergencies due to injury at Viet Duc hospital, from March 26th 2006 to Octorber 26th 2006. However, supervised cases were the patients under 18 years old who were examined and treated at the Department of Emergency. Results: During the period of study, 2536 patients under 18 years old were examined for injury, of which death and coming back home for death were 83 cases (3.27%). 974 children had emergency resulted from injury: male was more than female: 697 verus 227. The leading causes of child injury were fall and traffic accident, respetively 34% and 60%. The most common traumas were traumatic brain injury (45%), limbs injury (41%). Although most of cases had first aid at the hospitals in district or province level, the rate of non-first aid cases was high (34%). Conclusion: Child injury is a leading cause of child death in hospitals. Methods for prevention of child injury should focus on educating and propagandizing to minimize injuries caused by traffic accident and fall.

Objectives: Asymptomatic infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and test re-positivity after a negative test have raised concerns about the ability to effectively control the coronavirus disease 2019 (COVID-19) pandemic. We aimed to investigate the prevalence of COVID-19 asymptomatic and pre-symptomatic infections during the second wave of COVID-19 in Viet Nam, and to better understand the duration of SARS-CoV-2 infection and the dynamics between the evolution of clinical symptoms and SARS-CoV-2 test positivity among confirmed COVID-19 cases. Methods: We conducted a cohort analysis on the first 50 confirmed cases during the second COVID-19 wave in Viet Nam using clinical, laboratory and epidemiological data collected from 9 March to 30 April 2020. Kaplan-Meier estimates were used to assess time to clearance of SARS-CoV-2 infection, and log-rank tests were used to explore factors related to time to SARS-CoV-2 infection clearance. Results: Most cases (58%) had no typical signs or symptoms of COVID-19 at the time of diagnosis. Ten cases (20%) were re-positive for SARS-CoV-2 during infection. Eight cases (16%) experienced COVID-19 symptoms after testing negative for SARS-CoV-2. The median duration from symptom onset until clearance of infection was 14 days (range: 6–31); it was longer in re-positive and older patients and those with pre-existing conditions. Conclusion Asymptomatic and pre-symptomatic infections were common during the second wave of COVID-19 in Viet Nam. Re-positivity was frequent during hospitalization and led to a long duration of SARS-CoV-2 infection.
