[Clinical study on combined multi-disciplinary laparoscopic surgery].

OBJECTIVE: To investigate the clinic characteristics and efficacy of combined multi-disciplinary laparoscopic surgery. METHODS: Combined laparoscopic surgery was performed in 46 gynecological patients who concomitantly had gastrointestinal and urinary tract diseases as study group, and single gynecologic laparoscopic surgery in 40 patients as control group. The complications and mean time of operations, bowel function restoration, and hospitalization length were observed. RESULTS: The surgery of every patient was successful. None of the cases was transferred to open laparotomy. No complications occurred. The mean time of operations was significantly increased in study group (127 +/- 91) min compared with control group (100 +/- 80) min (P < 0.05). The recovery time of bowel function, as well as the mean time of hospitalization was not different between study group (20 +/- 10) h, (3.7 +/- 1.5) d and control group (19 +/- 10) h, (3.5 +/- 1.3) d (both P > 0.05). CONCLUSIONS: Combined multi-disciplinary laparoscopic surgery can be performed safely and effectively for gynecological patients complicated with gastrointestinal or urinary tract diseases.

[Surgical intervention of hepatocellular carcinoma with bile duct thrombi].

OBJECTIVES: To summarize the experience of surgical intervention for hepatocellular carcinoma (HCC) with bile duct thrombi (BDT), and to evaluate the influence on prognosis. METHODS: From 1994 to 2002, 15 patients with HCC and BDT who underwent surgical intervention were retrospectively analyzed. RESULTS: The operative procedures included hepatectomy with removal of BDT (n = 7), hepatectomy combined with extrahepatic bile duct resection (n = 4), thrombectomy through choledochotomy (n = 3), and piggy-back orthotopic liver transplantation (n = 1). The 1- and 3-year survival rates were 73.3% and 40%, respectively. Two patients survived over 5 year. The survival rate of patients with portal vein invasion was significantly lower than that of patients without portal vein invasion (P < 0.05). CONCLUSIONS: Surgical intervention was effective for patients with HCC and BDT. Operation after recurrence can prolong the survival time. Liver transplantation is a new operative procedure worthy of study.

[Experimental study of diode-laser induced thermocoagulation on hepatic tissue with scanner fiber tip].

OBJECTIVE: To seek a safe, efficient, and cost-effective technique for local thermo-ablation of hepatic cancer. METHODS: The livers from 16 healthy rabbits were thermocoagulated by diode-laser with scanner fiber tip, 6 w for 10 mins. At the same time, the temperatures were measured at 0, 5 and 10 mm from laser tip. The pre-thermocoagulative liver function was compared with that of 7 days post-thermocoagulation. The pathologic changes were also observed 1 month after laser thermocoagulation. RESULTS: All the rabbits survived and hepatic tissue temperatures at 0, 5, 10 mm from laser tip reached 96.39 degrees C +/- 3.97 degrees C, 60.79 degrees C +/- 6.21 degrees C, 46.10 degrees C +/- 4.58 degrees C respectively after 10 minutes of thermocoagulation. There were no significant differences in liver function parameters between rabbits of pre-laser thermocoagulation and of post-laser thermocoagulation. Thermocoagulated necrosis of liver tissue with surrounding fibrosis in a diameter of 26.0 mm was formed. Light microscopy revealed coagulative necrosis in the center of the coagulated area without surviving hepatic cells. CONCLUSION: The hepatic tissue can be coagulated safely and effectively by diode-laser with scanner fibertip, and such a technique may provide a new method for the treatment of hepatic carcinoma.
