ABSTRACT
BACKGROUND: Proliferative myositis is a rare benign tumor that is typically self-limiting and does not become malignant. It can be cured by simple resection without reported recurrence. Due to its rapid growth, hard structure and ill-defined borders, it can however be mistaken for malignant tumors such as sarcomas. CASE SUMMARY: We investigate the case of a 64-year-old male with proliferative myositis of the abdominal wall, who was preoperatively administered a needle aspiration biopsy and given a simple excision and patch repair. We then compared it with other similar cases to determine the effectiveness of this treatment method. CONCLUSION: Resection with follow-up observation has shown to be an effective treatment method for proliferative myositis. To avoid unnecessarily extended or destructive resection, a thorough and conclusive diagnosis is crucial, which requires adequate imaging and pathological knowledge.
ABSTRACT
OBJECTIVE: To summarize the experience in laparoscopic resection of true pancreatic cyst. METHODS: Five patients with true pancreatic cyst, including 1 case of pancreatic head cyst and 4 cases of distal pancreatic cyst, underwent laparoscopic resection. Among them one case with pancreatic head cyst and 4 cases of distal pancreatic cyst underwent simple laparoscopic cyst resection and one case of distal pancreatic cyst underwent laparoscopic distal pancreatectomy with resection of the spleen. The curative effects were evaluated. A follow-up lasting 2 approximately 33 months was conducted. RESULTS: All operations were successful with intraoperative blood loss of 50 to 150 ml. The patients could get up and move about 6 hours after the operation and were recovered and discharged 4 to 6 days later. Follow-up showed that all symptoms disappeared and no recurrence of cyst occurred. CONCLUSION: Laparoscopic resection of true pancreatic cyst is feasible with the advantages of reduced injury and earlier recovery.
