RESUMO
BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has a high recurrence rate and poor outcome. Lymph node (LN) metastasis, especially para-aortic LN (PALN), is an important prognostic factor. PALN assessment through sampling with frozen-section analysis is a validated method. Our aim was to evaluate the prognostic impact of PALN on overall survival (OS) in patients who underwent standard pancreaticoduodenectomy, lymphadenectomy with PALN sampling, as well as to identify other prognostic factors for survival. METHODS: Our retrospective study included 89 PDAC patients undergoing radical resection with PALN sampling. The patients were classified into PALN(+) (n = 11) and PALN(-) (n = 78). Univariate and multivariate analyses of 1-year and 3-year OS and Kaplan-Meier model were used. RESULTS: OS after 1-year for PALN(+) and PALN(-) was 18.2 and 56.4%, after 3-year was 15.4% and 0%, respectively. Tumor differentiation, LN metastasis (LN(-), LN(+) PALN(-), LN(+) PALN(+)) were significant prognostic factors in both univariate and multivariate analyses for 1-year OS, and neural invasion (PN) was the solely significant factor for 3-year OS (p < 0.05). Kaplan-Meier estimate showed that OS of PALN(+) and PN (+) was significantly lower than the negative group, respectively (p < 0.05). No statistical difference in OS was seen between LN(-) and LN(+) PALN(-); and between LN(+) PALN(-) and PALN(+) (p = 0.107). Patients with PN (-) PALN(+) had similar OS compared to PN (+) PALN(-) (p > 0.05). CONCLUSION: PDAC had a poor outcome despite treatment with radical resection. Further follow-up should be conducted to determine the role of surgery in PALN(+)and PN invasion.
RESUMO
INTRODUCTION: Tracheal invasion in thyroid cancer occurs in one-third of locally advanced cases and is the third most common site of infiltration following strap muscles and recurrent laryngeal nerves. Surgical resection plays an important role in the management strategy followed by either radioactive iodine or external beam radiotherapy. Nonetheless, there has been still controversy about the optimal extension of the surgery. Case Presentation. Total thyroidectomy, airway resection and bilateral neck dissection were performed in two cases diagnosed as advanced thyroid cancer with tracheal invasion (stage IV according to McCaffrey). The first case underwent partial tracheal resection and direct anastomosis by the V-shape technique, while the latter one required tracheal resection and permanent tracheotomy. After one-year follow-up, no evidence of tumor recurrence or any postoperative complications were found. CONCLUSION: Surgical resection still remains the mainstay of management for advanced thyroid cancer in general and for tracheal invasion cases in particular. The decision of surgical resection and tracheal reconstruction methods mostly depends on the extent of tracheal invasion.
RESUMO
Background: The transoral endoscopic thyroidectomy by vestibular approach (TOETVA) has been developed for thyroid microcarcinoma (TMC) treatment worldwide, with low rate of complications and excellent oncological results. However, this approach has still not been routinely performed. Thus, in this study, we aim to demonstrate the feasibility and safety of this technique in the clinical practice. Methods: In this prospective cohort study, 29 patients diagnosed TMC and clinically node negative underwent thyroidectomy and prophylactic central lymph node dissection by TOETVA. The clinicopathologic characteristics, surgical outcomes, and cosmetic results were evaluated. Results: The mean age was 34.7 ± 8.5 years. Three patients had underlying Grave's disease. Thyroid lobectomy with isthmusectomy was performed in the majority of cases (72.4%). All patients underwent prophylactic central node dissection. The mean number of retrieved central node was 7.8 ± 3.7 (3-19). Seven patients (24.1%) had lymph node metastasis in postoperative pathology. Among them, the mean number of metastatic lymph nodes was 2.1 ± 1.7 (1-5). The mean operative time was 121.2 ± 22.6 minutes. Four patients experienced transient hoarse and 1 patient had hematoma. Visual analog scale score on first postoperative day was 2.8 ± 1.4 (0-5). Most of patients were satisfied with cosmetic outcome. Conclusions: The TOETVA is new technique for TMC in Vietnam. The initial results of oncology, postoperative complications, and cosmetic supported the application of TOETVA in TMC.

Background: Various approaches for endoscopic thyroidectomy have been developed recently that improve the cosmetic outcome, and some are even scar free. In this study, we compared the safety and surgical outcomes of transoral endoscopic thyroidectomy vestibular approach (TOETVA) and unilateral axillobreast approach (UABA) thyroid surgery performed by a single surgeon. Materials and Methods: We conducted a prospective cohort study among 101 patients undergoing endoscopic thyroidectomy from 2018 to 2019 in our institution. The factors analyzed included patients' clinical characteristics, types and time of operation, blood loss, hospital stay, postoperative complications, and cosmetic satisfaction. Results: Among 101 patients, 51 underwent TOETVA and 50 had UABA surgery. UABA has shorter operative time for lobectomy (91.7 ± 16.5 minutes versus 50.4 ± 6.8 minutes, P < .001), whereas TOETVA is associated with less postoperative pain (visual analogue scale score day 1 of 4.6 ± 1.0 versus 5.8 ± 1.0, P < .001). There were no significant differences between TOETVA and UABA groups regarding rates of transient recurrent laryngeal nerve injury (9.8% versus 2.0%, P = .205) and hypothyroidism (11.5% versus 2.0%, P = .112), in which all patients fully recovered 6 months after surgery and most of them were satisfied with the cosmetic result. Conclusions: Both TOETVA and UABA have been shown to be effective and safe surgical options for endoscopic thyroid surgery, as well as gave excellent cosmetic result. Each approach has its own advantages and disadvantages, and choice of technique should be tailored for each individual, and patient preference should be integrated in the treatment plan.

INTRODUCTION: Choledochal cyst is a rare benign congenital dilation of the bile duct, which causes recurring disturbing symptoms without totally resection. Nonetheless, postoperative complications are still a common issue. A step up management for patients with complex complications is required to address the problem. CASE PRESENTATION: We report a 10-year-old child who suffered complex postoperative complications after choledochal cyst resection at the age of 5, including cholangitis, bilioenteric stenosis and cystolithiasis in remnant intrapancreatic duct cyst. She occasionally endured episodes of epigastric pain, fever and jaundice afterwards. As the symptoms and recurrent rate were worsen over time, the patient was admitted multiple times and various approaches (balloon dilation, percutaneous transhepatic biliary drainage, endoscopic retrograde cholangiopancreatography and laparoscopic surgery) were applied. Afterwards, patient recovered and discharged without any complications. CONCLUSION: Our case presented sophisticated complications relating to choledochal cyst that were successfully treated by a combination of modern minimal invasive techniques. Despite operated by experienced surgeons, the post-op complications are still a concerned problem due to difficult laparoscopic techniques, injuries of hepatic artery, infection and risk of malignancy. We suggested that minimal-invasive procedures should be considered first with the aim of relieving symptoms, biliary drainage and preparing for the reoperation.
RESUMO
INTRODUCTION: Tuberculosis (TB) remains a significant cause of morbidity and mortality in Vietnam. The current TB burden is unknown as not all individuals with TB are diagnosed, recorded and notified. The second national TB prevalence survey was conducted in 2017-2018 to assess the current burden of TB disease in the country. METHOD: Eighty-two clusters were selected using a multistage cluster sampling design. Adult (≥15 years of age) residents having lived for 2 weeks or more in the households of the selected clusters were invited to participate in the survey. The survey participants were screened for TB by a questionnaire and digital chest X-ray after providing written informed consent. Individuals with a positive symptom screen and/or chest X-ray suggestive of TB were asked to provide sputum samples to test for Mycobacterium tuberculosis by Ziehl-Neelsen direct light microscopy, Xpert MTB/RIF G4, BACTEC MGIT960 liquid culture and Löwenstein-Jensen solid culture. Bacteriologically confirmed TB cases were defined by an expert panel following a standard decision tree. RESULT: Of 87,207 eligible residents, 61,763 (70.8%) participated, and 4,738 (7.7%) screened positive for TB. Among these, 221 participants were defined as bacteriologically confirmed TB cases. The estimated prevalence of bacteriologically confirmed adult pulmonary TB was 322 (95% CI: 260-399) per 100,000, and the male-to-female ratio was 4.0 (2.8-5.8, p<0.001). In-depth interviews with the participants with TB disease showed that only 57.9% (95% CI: 51.3-64.3%) reported cough for 2 weeks or more and 32.1% (26.3-38.6%) did not report any symptom consistent with TB, while their chest X-ray results showed that 97.7% (95% CI: 94.6-99.1) had abnormal chest X-ray images suggesting TB. CONCLUSION: With highly sensitive diagnostics applied, this survey showed that the TB burden in Vietnam remains high. Half of the TB cases were not picked up by general symptom-based screening and were identified by chest X-ray only. Our results indicate that improving TB diagnostic capacity and access to care, along with reducing TB stigma, need to be top priorities for TB control and elimination in Vietnam.

INTRODUCTION: Lactating adenoma is a rare breast tumor which is commonly found in late pregnancy or lactation period. Despite its benign nature, lactating adenoma might develop aggressively and can be misdiagnosed as breast cancer. CASE PRESENTATION: We report a case of a 25-year-old female presenting with two large, ulcerative and bleeding breast masses. An open biopsy demonstrating lactating adenoma was considered discordant and surgery was performed to confirm the diagnosis. CONCLUSION: Careful clinical and histological evaluations are necessary to diagnose and manage lactating adenoma.
RESUMO
Solitary fibrous tumors (SFT) is a rare type of soft tissue tumors and there have been only a few reported cases of SFTs at the perineum region. We report a SFT below the pubic bone in a 35-year-old male causing compression on his corpus spongiosum. The patient underwent en bloc tumor resection with preservation of spermatic vessels and the bladder neck. Pathological evaluation and immunohistochemistry (IHC) staining with CD34(+), CD99(+), STAT6(+), S100(-) and Desmin(-) confirmed the diagnosis of SFT. Surgery plays a key role in treatment strategies and pathological examination with IHC is important in the diagnosis of SFTs.
RESUMO
INTRODUCTION: Chondrosarcoma is a malignant tumor originated from cartilage cells. The most common sites of chondrosarcoma are pelvis, femur and ribs. The temporo-mandibular joint (TMJ) chondrosarcoma is extremely rare, with approximately 30 cases reported in worldwide. PRESENTATION OF CASE: In this report, we present a case of chondrosarcoma in the left TMJ, which was successfully treated with surgery and radiation therapy. A 47 year-old women was admitted to our hospital with a mass in left pre-auricular region. On examination and para-clinical test results, the initial diagnosis was parotid gland cancer. In operation, the lesion was a mass originating from the left TMJ. Tumor resection was performed with close margin. The post-operative pathological result was well-differentiated chondrosarcoma. She was indicated adjuvant radiation therapy due to inadequate surgical therapy. There was no evidence of recurrence after 6 months follow-up. CONCLUSION: The TMJ chondrosarcoma is needed to distinguish from other diseases especially parotid gland tumor. Surgery and adjuvant radiation therapy are standard care with the aim of preserving joint function.
RESUMO
INTRODUCTION: In advanced gastric cancer, preoperative chemotherapy is associated with survival benefit. FOLFIRI has demonstrated promising results in terms of survival and tolerance, especially in patients with poor performance status. CASE PRESENTATION: A 59-year-old male, diagnosed with pT4bN2M0 gastric cancer, underwent gastrointestinal anastomosis and three cycles of EOX chemotherapy. Due to disease progression, he was switched to FOLFIRI regimen. After 12 cycles, the patient received a subtotal gastrectomy and D2 lymphadenectomy. Microscopic examination achieved pCR, and the patient has been surviving 34 months without recurrence. No severe toxicities of chemotherapy were recorded. CONCLUSIONS: FOLFIRI might be a safe and effective option in neoadjuvant treatment for advanced gastric cancer among patients with poor performance status or progression after first-line chemotherapy.
RESUMO
INTRODUCTION: Giant thyroid tumors can be associated with severely compressive symptoms and surgery is inevitable for treatment strategy. However, the risk of surgical complications is higher as well as the duration of operation may be longer than those of small thyroid tumors. PRESENTATION OF CASES: Two patients with large neck tumors were admitted with history of thyroid goiters for more than 10 years. Recently, the patients have complained of worsening compressive symptoms including dyspnea and dysphagia. Imaging work-up indicated a deviation and compression of trachea. Both patients underwent either lobectomy or thyroidectomy and were discharged without any complications. Final histological results were thyroid adenoma in both cases. CONCLUSION: Surgical management is considered as primary treatment for most patients with giant thyroid tumors. It is necessary to be aware of complications and careful dissection to archive a good outcome.
RESUMO
INTRODUCTION: Squamous cell carcinoma (SCC) of lower lip comprises over 25% of oral cancer. Surgical treatment plan for SCC patients includes tumor excision, lymph node dissection and reconstruction. CASE PRESENTATION: A 68-year-old patient was admitted with 1-year history of tumor in his lower lip. Examination revealed a large lower lip tumor with expansion to the upper lip and a 2 cm submental lymph node. Biopsy result of the tumor was SCC and fine needle aspiration result of the lymph node was metastasis SCC. He underwent a complete removal of the lower lip and 1/3 external of the upper lip plus dissection of bilateral cervical lymph node plus reconstruction with local flap. After a 4-hour operation and 14-day hospitalization, patient recovered with flap in excellent condition and without any complications. CONCLUSION: Treatment with tumor excision, lymph node dissection and reconstruction by local flap is primary treatment for patients with lower lip cancer. Choice of reconstruction method depends on various factors, whereas V-Y advancement flap presents dominant advantage in lower lip cancer treatment.
RESUMO
OBJECTIVES: With the rise in methadone maintenance therapy (MMT) for drug users in Vietnam, there has been growing interest in understanding if and how often MMT patients engage in concurrent illicit drug use while on methadone therapy in various settings. This study examined factors associated with concurrent opioid use among patients on MMT in a mountainous area in Vietnam. SETTING: One urban and one rural MMT clinics in Tuyen Quang province. PARTICIPANTS: Survey participants consisted of patients who were taking MMT at the selected study sites. A convenience sampling approach was used to recruit the participants. PRIMARY AND SECONDARY OUTCOME MEASURES: Participants were asked a series of questions about their socioeconomic status, current alcohol and tobacco use, health problems (measured by the EuroQol-Five Dimension-Five Level instrument), psychological distress (measured by Kessler score), and factors associated with current and/or previous drug use. Regression models were used to determine factors associated with concurrent drug use among MMT patients. RESULTS: Among the 241 male MMT patients included in the study, 13.4% reported concurrent opioid use. On average, the longer patients had been enrolled in MMT, the less likely they were to concurrently use drugs. Conversely, patients with higher levels of psychological distress were more likely to engage in concurrent drug use while on MMT. CONCLUSION: Longer duration of MMT was significantly correlated with reduced illicit drug use among participants. Higher levels of psychological distress were associated with increased use of illicit drugs among MMT patients. Regardless of distance, long-term MMT is still effective and should be expanded in mountainous areas.
