Purpose: This study sought to identify potential candidates for adjuvant radiotherapy and patterns of regional failure in patients who underwent curative-intent surgery for gallbladder cancer. Materials and Methods: Records for 70 patients with gallbladder cancer who underwent curative resection at a single institution between 2000 and 2016 were analysed retrospectively. No patients received adjuvant radiotherapy. Initial patterns of failure were evaluated. Regional recurrence was categorized according to the definitions of lymph node stations suggested by the Japanese Society of Hepato-Biliary-Pancreatic Surgery. Results: Median follow-up was 23 months. Locoregional recurrence as any component of first failure occurred in 29 patients (41.4%), with isolated locoregional recurrence in 13 (18.6%). Regional recurrence occurred in 23 patients, and 77 regional recurrences were identified. Commonly involved regional stations were #13, #12a2, #12p2, #12b2, #16a2, #16b1, #9, and #8. Independent prognostic factors for locoregional recurrence were ${\geq}pT2$ disease (hazard ratio [HR], 5.510; 95% confidence interval [CI], 1.260-24.094; p = 0.023) and R1 resection (HR, 6.981; 95% CI, 2.378-20.491; p < 0.001). Conclusion: Patients with pT2 disease or R1 resection after curative surgery for gallbladder cancer may benefit from adjuvant radiotherapy. Our findings on regional recurrence may help physicians construct a target volume for adjuvant radiotherapy.

Background Lymphatic malformation (LM) is a form of congenital vascular malformation with a low incidence. Although LM has been studied, no consensus has emerged regarding its cause or treatment. Methods In this study, we retrospectively evaluated 40 patients who visited our vascular anomalies center for the treatment of cervicofacial LM, which is a common manifestation of LM. The medical records of patients over a period of 12 years were reviewed and analyzed for commonalities regarding the diagnosis and the results of treatment. Results Suspected cervicofacial LM was confirmed through imaging studies. No difference in incidence was observed according to sex, and 73% of patients first presented with symptoms before the age of two years. The left side and the V2-V3 area were most commonly affected. No significant differences in incidence were observed among the macrocystic, microcystic, and combined types of LM. A total of 28 out of 36 patients received sclerotherapy as the first choice of treatment, regardless of the type of lesion. Complete resolution was achieved in only 25% of patients. Conclusions LM is important to confirm the diagnosis early and to choose an appropriate treatment strategy according to the stage of the disease and each individual patient's symptoms. When treatment is delayed or an incorrect treatment is administered, patient discomfort increases as the lesion gradually spreads. Therefore, more so than is the case for most other diseases, a team approach on a case-by-case basis is important for the accurate and appropriate treatment of LM.

Lymphatic filariasis is a common parasitic disease of cats in tropical regions including Thailand. The objective of this study was to determine the efficacy of ivermectin against microfilariae of Brugia pahangi in naturally infected cats. Eight cats naturally infected with B. pahangi were divided into control (untreated) and treated groups. Cats in the latter group were given ivermectin injection at 400 ${\mu}g/kg$ weekly for 2 months. Microfilariae were counted every week until 48 weeks. Microfilaremia was significantly decreased in the treated group 4 weeks after starting the treatment and become zero at week 9 and afterwards. On the other hand, cats in the control group had high microfilaremia throughout the study. It was successful to treat and control B. pahangi infection in naturally infected cats using ivermectin.

Chyloascities is an extravasation of milky chyle into the peritoneal cavity due to tumor , inflammation or rarely postoperative lymphatic trauma.It is an unusual complication that can lead to significant immunologic and nutritional consequences.We experienced one case of chyloascites after aorto-bifemoral bypass graft in a patient with aorto-iliac occlusive disease.The patient was a 62-year-old male, who suffered from severe progressive claudication for 5 months. A 16$\times$ 8mm gelsealed Dacron-Y shaped graft was used in arterial reconstruction. A bloody-milky fluid was drained through the operative wound from 3days after operation and evaluated biochemically.Diagnosis of chyloascites was made with repeated paracentesis and examination of the fluid.After Total parenteral nutrition[T.P.N] for 3 weeks from 6days after operation, chyloascites was controlled sufficiently and maintained a good graft-patency in abdominal sonogram.

Elephantiasis, which is the final stage of lymphedema, has swelling, papillomas and discharges in the skin. Although this disease is recorded in literature since 50 AD, the treatment is not yet. After all this time, complex lymphedema therapy (CLT) involving lymphatic massaging, bandaging, exercise, and skin care is becoming recognized as the best approach to care for people who develop lymphedema. The patient was a 30-year-old male who complained of swelling, papillomas, and discharges on left leg. He was received with CLT for 2 months, and the symptoms of him were improved.

Radiation therapy is an effective treatment modality for malignant disease of the head and neck, but it is not without risk and complication. Response of the larynx to radiotherapy varies from mild erythema to severe inflammation with edema and induration. possibly leading to necrosis of cartilage. These changes are due to an inflammatory reaction characterized by infiltration of polymorphonuclear leukocytes, vascular thrombosis, and obliteration of lymphatic channels. Late changes consist of telangiectasia of the skin, alopecia, loss of subcutaneous fat, degenerative changes in the connective tissues. But, radiation necrosis of laryngeal cartilage is an uncommon complication and it is a devastating process for which further necessitates surgical treatment. It is generally agreed that the only treatment for patient not responding to conservative measures is a total laryngectomy. We experienced 4 cases of delayed radionecrosis of the larynx who underwent radiation therapy for glottic cancer and hypopharyngeal cancer. We report these cases with review of literature.

Echinococcosis is a disease caused by the Echinococcus species that parasitizes in humans. Alveolar echinococcosis (AE) which is caused by Echinococcus multilocularis is harmful to humans. AE mainly occurs in the liver and can be transferred to retroperitoneal lymph nodes, lung, brain, bone, spleen and other organs through lymphatic and blood vessels. Cholangiocarcinoma can occur in of the intrahepatic and extrahepatic bile ducts and is more common in the hilar. We reported a case of hilar bile duct alveolar echinococcosis which was originally misdiagnosed an cholangiocarcinoma.

Intestinal lymphangiectasia is a rare disease which is causing protein-losing enteropathy. Treatment of intestinal lymphangiectasia can be a challenge for clinicians because of the lack of specific guidelines regarding pharmacological indications. We sought to introduce a diagnostic approach and suggest guidelines for treatment. After exclusion of secondary intestinal lymphangiectasia, magnetic resonance lymphangiography is a promising tool for the assessment of abnormal lymphatic lesions in primary intestinal lymphangiectasia. Determining the extent of the lesion provides direction for treatment options. Focal short-segment intestinal lymphangiectasia can be treated via intestinal resection or radiologic embolization after dietary therapy failure. Diffuse intestinal lymphangiectasia and extensive lymphangiectasia should be treated with several drugs with a full understanding of their mechanisms.

The glymphatic system hypothesis is a concept describing the clearance of waste products from the brain. The term "glymphatic system" combines the glial and lymphatic systems and is typically described as follows. The perivascular space functions as a conduit that drains cerebrospinal fluid (CSF) into the brain parenchyma. CSF guided to the perivascular space around the arteries enters the interstitium of brain tissue via aquaporin-4 water channels to clear waste proteins into the perivascular space around the veins before being drained from the brain. In this review, we introduce the glymphatic system hypothesis and its association with fluid dynamics, sleep, and disease. We also discuss imaging methods to evaluate the glymphatic system.

The field of artificial intelligence is rapidly evolving, and there has been an interest in its use to predict the risk of lymph node metastasis in T1 colorectal cancer. Accurately predicting lymph node invasion may result in fewer patients undergoing unnecessary surgeries; conversely, inadequate assessments will result in suboptimal oncological outcomes. This narrative review aims to summarize the current literature on deep learning for predicting the probability of lymph node metastasis in T1 colorectal cancer, highlighting areas of potential application and barriers that may limit its generalizability and clinical utility.
