RESUMEN
The Asian expert working group completed the 2022 consensus on vernal keratitis (VKC), which provides detailed information on the definition, classification, clinical manifestation, diagnosis and treatment of VKC in Asia and identifies unmet treatment needs, including: (1) lack of clear criteria for the diagnosis and treatment of patients with VKC.The pathogenesis of the disease is unclear, and anti-allergy therapy is often ineffective in patients with moderate or severe VKC; (2) the need for standardized treatment and management strategies.Treatment and management of patients with the same severity varies widely among Asian countries, with a lack of clear, standardized guidelines and grading systems; (3) safety and iatrogenic complications; (4) optimal dosing regimen for pharmacologic treatment.In this article, the aspects mentioned above were interpreted and analyzed in the context of the Expert Consensus on the Diagnosis and Treatment of Allergic Conjunctivitis in China ( 2018), with a view to helping the prevention and treatment of VKC in China.
RESUMEN
Objective:To evaluate the preoperative localization value of endoscopic ultrasound guided fine needle tattooing (EUS-FNT) for laparoscopic distal pancreatectomy in pancreatic lesions with a maximum diameter ≤3 cm.Methods:From November 2017 to October 2022, at the Second Affiliated Hospital of Soochow University, the data of patients with pancreatic lesions ≤3 cm who underwent laparoscopic distal pancreatectomy were retrospectively analyzed. Eight patients who underwent EUS-FNT assisted laparoscopic distal pancreatectomy were included in the fine needle tattooing (FNT) combined laparoscopic group. And 14 patients who underwent simple laparoscopic distal pancreatectomy were taken as the simple laparoscopic group. The success rate and complications of EUS-FNT were observed. The differences in operation time, surgery-related complications and complete resection rate of lesions between the two groups were compared. Mann-Whitney U test and descriptive analysis were used for statistical analysis. Results:In the FNT combined laparoscopic group, the lesions of 4 cases were located in the pancreatic body and 4 cases in the pancreatic tail. In the simple laparoscopic group, the lesions of 4 cases were located in the pancreatic body and 10 cases in the pancreatic tail. There was a significant difference in lesion size between the two groups (14.5 mm (10.8 mm, 16.5 mm) vs. 27.0 mm (23.5 mm, 30.0 mm), Z=-3.09, P=0.001). In the FNT combined laparoscopic group, EUS-FNT was successfully performed in all 8 patients. The average time of laparoscopy after EUS-FNT was (98.4±8.8) min. The marks were clearly visible under the laparoscopic field of view, and no complications such as abdominal hemorrhage and hematoma were observed. Laparoscopic pancreaticocaudectomy was performed in 5 cases and pancreaticocaudectomy plus splenectomy in 3 cases. The median operation time was 192.5 min (176.3 min, 203.8 min). The amount of intraoperative bleeding was large in 2 patients and blood transfusion was needed. The lesions were one-time completely resected in all 8 patients. The postoperative pathology were 6 cases of pancreatic neuroendocrine neoplasm, 1 case of intraductal papillary mucinous neoplasm (IPMN), and 1 case of solid pseudopapilloma. In the simple laparoscopic group, laparoscopic pancreaticocaudectomy was performed in 2 cases and pancreaticocaudectomy plus splenectomy in 12 cases. The median operation time was 202.5 min (192.8 min, 235.0 min), which was longer than that of FNT combined laparoscopic group, but the difference was not statistically significant ( P>0.05). The amount of intraoperative bleeding was large in 2 patients and blood transfusion was needed. In 1 patient with pancreatic body lesions, no lesion was found in the specimen examination after the first pancreatectomy, and the lesions were completely resected after the second partial pancreatectomy. Active abdominal hemorrhage occurred in 1 patient on the second day after operation, and underwent interventional embolization for hemostasis. Two weeks after surgery, 1 patient was found to have a encapsulated fluid with a long diameter of 6 cm around the pancreas by computed tomography re-examination 2 weeks after surgery. The postoperative pathology were 5 cases of pancreatic neuroendocrine neoplasm, 2 cases of IPMN, 1 case of solid pseudopapilloma, 1 case of pancreatic cyst with glandular low-grade intraepithelial neoplasia, 1 case of ectopic spleen, and 4 cases of pancreatic ductal adenocarcinoma. Conclusion:EUS-FNT can effectively localize small pancreatic lesions before laparoscopic distal pancreatectomy, shorten the operation time and improve the complete resection rate under laparoscopy.
