The Effect of Percutaneous Flexor Tenotomy on Healing and Prevention of Foot Ulcers in Patients With Claw Deformity of the Toe.

Claw deformity of the foot is frequently seen in patients with diabetes mellitus. Percutaneous flexor tenotomy is a simple surgical procedure for the treatment of foot ulcers on the distal end of the toe caused by this deformity. This procedure can also be performed to prevent ulcers in claw toes that are at risk of ulceration. The aim of this study is to investigate whether percutaneous flexor tenotomy is an effective surgical method for treatment and prevention of toe ulcers in patients with claw deformity. This retrospective study, with a median follow-up of 13.4 (1 to 66.7) months, included all consecutive patients who underwent percutaneous flexor tenotomy in 2 hospitals between July 2012 and April 2017. In total, 101 feet underwent flexor tenotomy: 84 (83.3%) therapeutic and 17 (16.7%) prophylactic. Of the 84 therapeutic procedures, 95.1% healed, with a median healing time of 27 days. In 11 (13.3%) therapeutic procedures, a reulceration was recorded. In the therapeutic group, 4 (4.8%) infections and 1 (1.2%) amputation of the digit occurred. In the 17 prophylactic procedures, local bleeding was recorded in 1 (5.9%). In the prophylactic group, 2 ulcers occurred. In 77 (76.2%) of all procedures, patients had diabetes mellitus. In conclusion, percutaneous flexor tenotomy is an effective, safe, and minimally invasive procedure for the treatment and prevention of toe ulcers in patients with claw deformity.

Unique case of pneumomediastinum due to penetrating injury to the mediastinum.

Pneumomediastinum is a rare condition, and mostly occurs following traumatic or iatrogenic tracheal and oesophageal perforation, but spontaneous pneumomediastinum has also been described. We report a case of a 17-year-old woman who presented with a penetrating neck wound after a fall down the stairs. She had an extensive pneumomediastinum without signs of tracheal or oesophageal laceration, rib fractures, pneumothorax or haematothorax. The contaminated wound was surgically explored and extensively lavaged. Prophylactic antibiotic treatment was given and the patient recovered without complications. Direct perforating trauma to the mediastinum is a severe entity, but can be treated by lavage and prophylactic antibiotic therapy.

Laparoscopic resection of a residual retroperitoneal tumor mass of nonseminomatous testicular germ cell tumors.

BACKGROUND: Resection of a residual retroperitoneal tumor mass (RRRTM) is standard procedure after combination chemotherapy for metastatic nonseminomatous testicular germ cell tumors (NSTGCT). METHODS: At the University Medical Center Groningen, 79 consecutive patients with disseminated NSTGCT were treated with cisplatin combination chemotherapy between 2005 and 2007. Laparoscopic RRRTM was performed for patients with RRTM located less than 5 cm ventrally or laterally from the aorta or the vena cava. The 29 patients who fulfilled the criteria had a median age of 25 years (range, 16-59 years). The stages of disease before chemotherapy treatment according to the Royal Marsden classification were 2A (n = 6, 21%), 2B (n = 14, 48%), 2C (n = 3, 10%), and 4 with a lymph node status of N2 (n = 6, 21%). RESULTS: The median duration of laparoscopy was 198 min (range, 122-325 min). The median diameter of the RRTM was 21 mm (range, 11-47 mm). Laparoscopic resection was successful for 25 patients (86%). Conversion was necessary for three patients (10%): two due to bleeding and one because of obesity. One nonplanned hand-assisted procedure (3%) also had to be performed. Histologic examination of the specimens showed fibrosis or necrosis in 12 patients (41%), mature teratoma in 16 patients (55%), and viable tumor in 1 patient (3%). The median hospital stay was 1 day (range, 1-6 days). During a median follow-up period of 47 months (29-70 months), one patient experienced an early relapse (1 month after the end of treatment) (4%). CONCLUSION: For properly selected patients, laparoscopic resection of RRTM is an improvement in the combined treatment of disseminated NSTGCT and associated with a short hospital stay, minimal morbidity, rapid recovery, and a neat cosmetic result. Long-term data to prove oncologic efficacy are awaited.
