[source] Resection of renal metastases to the pancreas: a surgical challengeHPB, Issue 3 2003D Zacharoulis Background Metastasis to the pancreas from renal cell carcinoma (RCC) is distinctly uncommon. Most cases are detected at an advanced stage of the disease and are thus unsuitable for resection. A solitary RCC metastasis to the head of pancreas is rarely encountered and, although it is potentially amenable to surgical resection, surgeons may be hesitant to perform pancreatoduodenectomy. Cases outlines Two patients with a solitary RCC metastasis to the head of pancreas were treated by pancreatoduodenectomy, while a third with multiple RCC metastases declined any treatment. Two of the patients were asymptomatic, and one presented with anaemia and mild abdominal pain. Computed tomography (CT) and angiography were used to exclude other metastases and to assess resectability of the pancreatic tumour. All three patients are still alive, those with resectable disease at 2 years and 9 years and the one with irresectable disease at 4 years. Discussion Isolated RCC metastasis to the pancreas is a rare event. Patients present either on follow-up imaging or with symptoms such as mild abdominal pain, weight loss, jaundice, anaemia or gastrointestinal bleeding (whether occult or overt). Dynamic spiral CT can visualise the tumour and exclude distant metastasis. Angiography often reveals a highly vascularised tumour and will help to assess resectability. In the absence of widespread disease, pancreatic resection can provide long-term survival in metastatic RCC, although few cases have been reported with lengthy follow-up. The prognosis is better than for pancreatic adenocarcinoma. [source] Nitric oxide in wound-healingMICROSURGERY, Issue 5 2005Jeff S. Isenberg M.D., M.P.H. Modulation of the complex process of wound-healing remains a surgical challenge. Little improvement beyond controlling infection, gentle tissue handling, and debridement of necrotic tissue has been had in the modern era. However, increasing appreciation of the process from a biomolecular perspective offers the potential for making significant strides in wound modulation. The bioactive molecule nitric oxide was found to have wide-ranging impact on cellular activities, including the cellular responses engendered by wound healing. Current research suggests that nitric oxide and several nitric oxide donors can exert biologic effects, although the particular net responses of cells contributing to wound repair are context-dependent. © 2005 Wiley-Liss, Inc.

[source] Laparoscopic sentinel node navigation surgery for early gastric cancerASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 1 2009H Takeuchi Abstract The sentinel node (SN) concept has revolutionized how the surgical staging of both melanoma and breast cancer are approached. Applying this concept can yield benefits for the patient by avoiding various complications relating to unnecessary prophylactic regional lymph node dissection in cases with negative SN for cancer metastasis. Clinical application of SN mapping for early gastric cancer had been controversial for years. However, single institutional results of laparoscopic SN mapping for early gastric cancer are considered acceptable in terms of detection rate and accuracy in determining lymph node status. For early stage gastric cancer such as cT1N0M0 , in which a better prognosis was generally achieved through conventional surgical approaches , an individualized, minimally invasive surgery that might retain the patient's quality of life should be established as the next surgical challenge. Although there are many issues still to resolve, laparoscopic minimized gastrectomy with SN navigation surgery or combined endoscopic mucosal resection and endoscopic submucosal dissection has the potential to achieve this goal. [source] Required length of follow-up after transanal advancement flap repair of high transsphincteric fistulasCOLORECTAL DISEASE, Issue 7 2009L. E. Mitalas Abstract Objective, Repair of high perianal fistulas presents a major surgical challenge. Transanal advancement flap repair (TAFR) provides a useful tool in the treatment of these fistulas. Initially promising results have been reported. More recent studies indicate that TAFR fails in one out of three patients. The aim of the present study was to determine the appropriate length of follow-up needed to assess the healing rate after TAFR of high transsphincteric fistulas. Method, Between 1992 and 2000 a consecutive series of 80 patients with a high transsphincteric fistula of cryptoglandular origin underwent TAFR. Medical records of all patients were studied. The initial healing rate and the median healing time were assessed. The initial outcome was successful in 54 patients. The medical records revealed that only one of these patients presented with a recurrent fistula after 28 months. The other 53 patients were sent a questionnaire in 2006 aimed to determine whether they had any complaints or signs of a recurrent fistula. Results, The initial healing rate was 68%. The median healing time was 3.6 months. The completed questionnaire was returned by 48 patients. None of these patients reported any complaints or signs of a recurrent fistula. Median duration of follow-up in these patients was 92 months. Conclusion, At a median time interval of 3.6 months fistula healing was observed in 54 patients (68%). Only one patient (2%) encountered a recurrence. The length of follow-up can be restricted to the healing time. [source] Extended surgery for local recurrence and advanced rectal cancerCOLORECTAL DISEASE, Issue 2006P. M. Sagar Abstract Although much effort has been directed at reducing the incidence of local recurrence after surgical resection of rectal cancer, there remain a significant number of patients who will develop local recurrence without evidence of metastatic disease. Such patients, as well as patients with locally advanced rectal cancer at presentation, may represent a surgical challenge. Application of sound surgical principals and team work can lead to a good long term outcome. This paper sets out to discuss the philosophy and techniques involved in the surgical management of such patients. [source] | ||||||||||
