[Damage control laparotomy for haemorragic abdominal trauma. A retrospective multicentric study about 109 cases].

AIM OF THE STUDY: Damage control laparotomy is a new approach to the more severe abdominal traumas. It stems from a better understanding of the physiopathology of the haemorragic shock. PATIENTS AND METHODS: A national retrospective study from 27 centers about 109 trauma patients who underwent a damage control procedure between January 1990 and December 2001, is analysed. Surgical procedures included 97 hepatic packing, 10 abdominal packing, 4 exclusive skin closure, 1 open laparotomy technique and 3 digestive stapplings. RESULTS: The mortality rate is 42%. Eleven abdominal compartment syndromes have occurred with 7 decompressive laparomy (4 deaths). CONCLUSION: This study is based on the largest series of damage control laparotomy published in France. Results in terms of mortality and morbidity are similar to those of published studies from the USA.

A new ileal pouch salvage technique.

Restorative proctocolectomy with ileal pouch-anal anastomosis has become the procedure of choice for the surgical treatment of ulcerative colitis. Fistulas originating from the ileal pouch are uncommon but serious complications, sometimes leading to failure of the operation. We describe a technique to treat and salvage a pouch involved in a chronic fistulating ileal J-pouch-anal anastomosis by disconnecting the pouch, turning it inside out after repair, and reanastomosing it to the dentate line.

[Radiofrequency ablation of malignant hepatic tumors. Preliminary experience apropos of 25 cases].

STUDY AIM: Radiofrequency (RF) ablation of malignant hepatic tumors is an interesting and recent technique which offers new treatment possibilities. In this study, the preliminary findings have been reported on 25 patients with hepatic tumors who received RF treatment between January 1998 and February 2000. PATIENTS AND METHODS: Twenty-five patients (11 cases of hepatocellular carcinoma, HCC; and 14 cases of liver metastases, LM) underwent RF treatment. Thirty tumors (range: 10 to 54 mm in diameter) out of a total of 63 were destroyed by RF: 13 HCC (average diameter: 32 mm) and 17 LM (average diameter: 26 mm). Treatment consisted of six percutaneous and 19 surgical RF procedures. In the surgical group, there were 11 cases of hepatectomy: right hepatectomy in five patients with segment IV enlargement in one case, and sub-segmentectomy in six other patients. In all cases, hepatic tomodensitometry was performed at one month post-treatment and then every three months. RESULTS: Postoperative portal thrombosis occurred in two patients, one of whom died. Other postoperative complications were observed in five patients. During the mean follow-up period of 14 months (range: 2 to 28 months), two patients died (carcinosis, ascitic decompensation), two and four months respectively after RF treatment. In situ recurrence occurred in four HCC and two LM patients. Three HCC and four LM patients developed new hepatic or extra-hepatic lesions. CONCLUSION: RF is a particularly interesting technique for the treatment of bilobar or unresectable metastases. It appears to be equally as efficient as other local treatments for small-sized HCC. However, technical improvements remain necessary to increase the destructive field covered by RF. A more important follow-up is needed so that the long-term efficacy and specific role of this new therapy can be accurately assessed.

[Self-expandable metal stent in the treatment of obstructive cancer of the left colon. Preliminary results and review of the literature].

AIM: To report our preliminary experience with self-expandable metal stent in the treatment of acute malignant obstruction of the left colon and to review the literature on this specific subject. PATIENTS AND METHODS: From March to September 1999, 8 consecutive patients with a mean age 71 were admitted as an emergency for acute malignant obstruction of the left colon. A self-expandable metal stent was inserted under radioscopic and, in 4 cases, endoscopic guidance. The patients then underwent bowel preparation before operation, if required. RESULTS: There was no mortality. Bowel preparation was satisfactory in 6 cases. Complications occurred in 1 patient, who was operated on day one for peritonitis due to perforation of the tumour by the prosthesis inserted after dilatation. Another six patients were operated: 2 had resection followed by anastomosis; 3 had resection and anastomosis protected by ileostomy; 2 had Hartmann's procedure. The last patient retained the prosthesis as palliation. In the literature, self-expandable metal stent application in obstructed carcinoma of the left colon gives satisfactory results. CONCLUSION: Based on our experience and a review of the literature, we provide practical recommendations when inserting self-expandable metal stents for acute malignant left colonic obstruction.
