RESUMEN
Tension pneumomediastinum is uncommon but it is a rapidly progress condition that can lead to cardiogenic shock. Mediastinal decompression is an emergency procedure and the knowledge of this technique is a life-saving treatment.

BACKGROUND/AIMS: To analyze retrospectively the operative results and five-year survival after single-stage resection and primary anastomosis for right- or left-sided colonic malignant obstruction. METHODOLOGY: From 1994 to 2002, 83 patients with acute obstruction due to primary cancer underwent a one-stage procedure, 36 (43.3%) for cancer of the right and 47 (56.7%) of the left colon. Of the 47 patients with left acute obstruction, 45 were treated with intraoperative colonic on-table lavage for decompression and wash-out before resection and anastomosis. Long-term survival was compared with the outcome of 369 patients with colonic cancer without obstruction 144 (39%) right and 225 (61%) left. RESULTS: Overall operative morbidity and mortality were 25.3% and 6%, respectively. Overall anastomotic leakage rate was 6%. Kaplan-Meier curves showed five-year survival rates poorer for patients operated on for obstructing malignancy than those observed for patients without obstruction (p=0.0001, Log-Rank test), obstructing malignancy was associated with more advanced age (p<0.0005) and staging of the cancer. CONCLUSIONS: One-stage resection and primary anastomosis can be applied to the majority of patients with malignant colonic obstruction and it allows achieving excellent operative results. Obstructing colonic cancer proved to be associated to a worse long-term survival.

BACKGROUND: The ever increasing number of, especially, adults waiting for a liver transplantation necessitates to develop techniques allowing to extend the available donor liver pool. MATERIALS AND METHODS: Between November 1988 and December 2004, 37 (6.6%) of 559 adults underwent split liver transplantation at Saint-Luc Hospitals. There were 36 were right and one left split procedures; 27 split grafts were obtained ex-situ and 10 in-situ. Results of these series are analysed and compared to literature data of split liver transplantation. RESULTS: Three and 12 months patient survival rates were 89.2% and 78.4% respectively. Five years actuarial patient survival was 75.7%. Early (< 3 months) and late (> 3 months) mortality rates were 10.8% (4 pat.) and 21.6% respectively. Early mortality was significantly higher in case of urgent split liver transplantation (3/5 patients vs. 2/32 elective patients--p 0.001). At present 25 patients are alive, with a mean Karnofsky score of 90%. Three and 12 months graft survival rates were 91.7% and 87.1% respectively. Three and one grafts were lost due to primary and early graft non-function. In-situ split grafts had shorter mean warm, cold, total ischemia and operating times as well as less need for blood transfusion; all these differences were however not statistically significant. Surgical complications occurred in 19 (51%) patients. All but one complication occurred early (< 3 months). There were sixteen biliary complications in 13 (35.1%) patients: 9 anastomotic stenoses, 3 anastomotic and 4 transection margin leakages. Six vascular complications occurred in 6 (15.2%) patients: three arterial and 3 portal vein thromboses. Seven (18.9%) patients had a postoperative bleeding. CONCLUSIONS: Graft and patient survival rates of split liver transplantation can be compared to those of classic liver transplantation. However the care of these patients is demanding due to the high number of technical complications. Results of split liver transplantation must be further improved in order to foster it's more widespread use necessary to overcome the actual shortage of liver allografts.

The aim of the study was to evaluate the results of laparoscopic pancreatectomy for pancreatic tumours. Four women and three men underwent laparoscopic pancreatectomy and were recruited into the study retrospectively over the period from June 2002 to February 2004. Pancreaticoduodenectomy (n = 4), intermediate pancreatectomy (n = 1) and distal pancreatic resection with splenectomy (n = 2) were successfully performed. Operative mortality was nil. The postoperative morbidity included two low-output pancreatic leaks. Mean operating time, blood loss and hospital stay were 342 minutes, 289 mL and 14 days, respectively. The pathological diagnosis was ductal adenocarcinoma in one, neuroendocrine tumour in five and metastatic melanoma in one. All patients are still well after a median follow-up of 7 months (range: 1-20 months). The patients appear to benefit from laparoscopic pancreatectomy for pancreatic tumours. The minimally invasive approach ensures adequate treatment but requires the expertise of highly skilled laparoscopic surgeons.
