Soft tissue reconstruction with omental free flap in complex upper extremity injuries: report of 13 cases.

Although there is a wide list of free flaps options for soft tissue reconstruction of complex upper extremity injuries, the omental flap has some useful anatomical and biochemical advantages. We report 13 patients who underwent hand or upper extremity reconstruction with omental free flaps. Nine patients had extensive tissue damage, resulting with digital cyanosis and hypothermia, and some of them with areas of cutaneous necrosis, or avulsed tissues with tendons and bones exposed or infected. The remaining four patients had minor extensive tissue damage without circulatory problems. Patient's average age was 34.6 years. Twelve flaps were harvested through laparotomy and one laparoscopically. All flaps were covered with a skin graft. None of the flaps were lost. The average follow-up time was 20 months. There was one major and two minor donor site complications. One patient had minor loss of the skin graft in the recipient site, and two required minor additional surgeries to improve the appearance or function of the hand or upper extremity. There were no late abdominal complications in any patient. The morphological appearance and functional results were favorable in 11 of them, and permitted their reincorporation into society without the need for additional complex surgeries. Only two patients had a poor outcome. Our experience confirms that the omental flap may be a good option for reconstruction of some complex hand and upper extremity injuries.

Pancreaticoduodenectomy in a Latin American country: the transition to a high-volume center.

OBJECTIVE: To analyze data in a single institution series of pancreaticoduodenectomies (PD) performed in a 7-year period after the transition to a high-volume center for pancreatic surgery. BACKGROUND: PD has developed dramatically in the last century. Mortality is minimal yet complications are still frequent (around 40%). There are very few reports of PD in Latin America. METHODS: Data on all PDs performed by a single surgeon from March 2000 to July 2006 in our institution were collected prospectively. RESULTS: During the study's time frame 122 PDs were performed; 84% were classical resections. Mean age was 57.9 years. Of the patients, 51% were female. Intraoperative mean values included blood loss 881 ml, operative time 5 h and 35 min, and vein resection in 14 cases. Both ampullary and pancreatic cancer accounted for 34% of cases (42 patients each), 5.7% were distal bile duct and 4% duodenal carcinomas. Benign pathology included chronic pancreatitis, neuroendocrine tumors, cystic lesions, and other miscellaneous tumors. Overall operative mortality was 6.5% in the 7-year period, 2.2% in the later 5 years. There was a total of 75 consecutive PDs without mortality. Of the patients, 41.8% had one or more complications. Mean survival for pancreatic cancer was 22.6 months and ampullary adenocarcinoma was 31.4 months. CONCLUSION: To our knowledge, this is the largest single surgeon series of PD performed in Latin America. It emphasizes the importance of experience and expertise at high-volume centers in developing countries.
