Although several studies have presented the intratendinous ganglion of the foot and ankle, there are only few reported cases, and no cases of recurrence or secondary surgery have been reported.CASE SUMMARY We present the case of a 32-year-old man with an intratendinous ganglion of the second extensor digitorum brevis(EDB) tendon that recurred after ganglion excision. Magnetic resonance imaging(MRI) performed before the first surgery was reviewed to analyze the causes of the recurrence. We confirmed that there was a lack of satellite detection. After recurrence, MRI revealed an extratendinous lesion, tenosynovitis, and intratendinous ganglion of the second EDB tendon. Since the second EDB tendon can compensate for the extrinsic muscle, en bloc resection was performed alone. In addition, meticulous excision and synovectomy were performed for extra-tendinous lesions and tenosynovitis, respectively. The patient returned to daily life without any functional problems or recurrence.CONCLUSION If removal of the affected tendon is not fatal, en bloc resection should first be considered to prevent incomplete excision and intraoperative leakage. When planning surgical excision, it is necessary to evaluate the presence of satellite lesions along the course of the affected tendon.展开更多

Objective: To promote a technique by using a gamma probe that asses intraoperatively the adequacy of the lesion curettage through a minimal invasive procedure. Methods: Reviewing the technique steps through 4 cases of osteoid osteoma surgical removal. Results: Four patients diagnosed with osteoid osteoma and moved to surgical removal. During the operation, excision of the tumour was assessed by a gamma probe, avoiding leaving residual lesion in the field. Operating time was not prolonged, so as the cost of the operation was not increased. Conclusions: Surgical excision of osteoid osteoma in spine region is still the gold standard method. Avoiding recurrence of the lesion is important. The use of gamma probe is an effective and economic solution.展开更多

From the wide variety of treatment options, surgical resection and liver transplantation are the only therapeutic ones. However, due to shortage of liver grafts, surgical resection is the most common therapeutic modality implemented. Owing to rapid technological development, minimally invasive approaches have been incorporated in liver surgery. Liver laparoscopic resection has been evaluated in comparison to the open technique and has been shown to be superior because of the reported decrease in surgical incision length and trauma, blood loss, operating theatre time, postsurgical pain and complications, R0 resection, length of stay, time to recovery and oral intake. It has been reported that laparoscopic excision is a safe and feasible approach with near zero mortality and oncologic outcomes similar to open resection. Nevertheless, current indications include solid tumors in the periphery < 5 cm, especially in segments Ⅱ through Ⅵ, while according to the consensus laparoscopic major hepatectomy should only be performed by surgeons with high expertise in laparoscopic and hepatobiliary surgery in tertiary centers. It is necessary for a surgeon to surpass the 60-cases learning curve observed in order to accomplish the desirable outcomes and preserve patient safety. In this review, our aim is to thoroughly describe the general principles and current status of laparoscopic liver resection for hepatocellular carcinoma, as well as future prospects.展开更多

It is seen mainly in the third trimester of pregnancy and in the postpartum period. Clinically, it is a solid mass, mobile typically benign but its character of rapid evolution is reminiscent of phyllodes tumors, sarcomas and galactoceles. The definitive diagnosis is histological. We report a case of lactating adenoma in a 26-year-old lactating woman, third procedure, second pare, with a history of tumor resection of the outer quadrants of the left breast, 9 months ago, whose histology evoked a fibrotic disease, cystic breast associating non-specific subacute mastitis with suppuration. Received for recurrence of a tumor in the left breast which was the site of a polylobed mass of about 10/5 cm occupying 3/4 of the breast with mobile ipsilateral axillary adenopathies. A micro tru-cut biopsy was performed and the histology was in favor of a lactating breast adenoma with no signs of malignancy. She underwent surgical excision, the consequences of which were simple.展开更多
