Chinese Journal of Minimally Invasive Surgery 2001;0(05):-
Objective To investigate the feasibility and safety of laparoscopic myomectomy in patients with large uterine myoma and the tumor located at special sites. Methods A retrospective study of 142 patients underwent laparoscopic myomectomy was done.In the patients,all the myomas were ≥10 cm in diameter;located at the cervix,uterus posterior wall near to the isthmic uteri,or broad ligament.The procedure was completed according to the volume and location of the tumors.For large myomas,the muscle layer was resected to remove the tumor,after removing the major part of the lesion(cut into pieces before moving out),the rest small parts were cut completely.Ligation was used for large tumors with sufficient blood supply in the surface or subserous myomas.For the myomas located in the broad ligament,the ligament was opened to pull out the tumor,and then the tumor was cut into pieces and resected at the root. Results The procedure was completed by laparoscopy in all of the patients,except in one who received laparoscopy-assisted resection.The removed tumors weighed 44 to 1903 g.The operation time ranged from 30 to 175 minutes.Intraoperative blood loss was 10 to 800 ml.No serious complications occurred.Among the cases,follow-up was available in 68 patients for 2 years.During the period,ultrasonography showed recurrent myoma in 2 patients. Conclusions With the improvement of the skills of laparoscopic myomectomy,indications for the laparoscopic operation can be widened.

OBJECTIVETo explore different regulatory effects of electroacupuncture (EA) at the same acupoint on the heart and the stomach.
METHODSEighty male SD rats were randomly divided into eight groups equally, i.e., the Neiguan (PC6) group, the Quchi (LI11) group, the Tianshu (ST25) group, the Danzhong (RN17) group, the Zusanli (ST36) group, the Sanyinjiao (SP6) group, the Xinshu (BL15) group, and the Weishu (BL21) group, 10 in each group. The regulatory effects of EA (2/15 Hz, 3 mA, 2 min) at different acupoints on the gastric motility (intragastric pressure) and the cardiac function (the left ventricular pressure) were observed. The mean values of effect of two-min pre-EA and after-EA were compared.
RESULTSCompared with the pre-EA in the same group, the left ventricular pressure decreased in the Neiguan (PC6) group, the Quchi (LI11) group, the Danzhong (RN17) group, the Sanyinjiao (SP6) group, and the Xinshu (BL15) group (P <0.05). The intragastric pressure increased in the Quchi (LI11) group, the Zusanli (ST36) group, the Sanyinjiao (SP6) group, and the Xinshu (BL15) group, while it decreased in the Tianshu (ST25) group, the Danzhong (RN17) group, and the Weishu (BL21) group (P <0.05). The difference of the left ventricular pressure was sequenced from high to low as Xinshu (BL15) >Danzhong (RN17) >Neiguan (PC6) >Sanyinjiao (SP6) >Quchi (LI11). The difference of the intragastric pressure was sequenced from high to low as Tianshu (ST25) >Weishu (BL21) > Xinshu (BL15) > Danzhong (RN17) > Zusanli (ST36) > Sanyinjiao (SP6) > Quchi (LI11).
CONCLUSIONSEA at the same acupoint (2/15 Hz, 3 mA) showed different regulatory effects on the heart and stomach. There existed some difference in the direction and size due to the acupoint location, meridians, dominant nerve segment or relating organs. A fixed effect direction to the specific target was also shown.

OBJECTIVE: To study the effects of Shengji Huayu Recipe (a traditional Chinese medicine compound recipe for resolving stagnation and promoting granulation) and its decomposed formulas (Huayu Recipe for resolving stagnation and Shengji Recipe for promoting granulation) on the synthesis of collagen types I and III in granulation tissue of rats in early wound healing. METHODS: Twenty-four male Sprague-Dawley (SD) rats with full-thickness skin lesion were randomized into 4 groups: Shengji Huayu Recipe-treated group, Shengji Recipe-treated group, Huayu Recipe-treated group and untreated group. Collagen types I and III in granulation tissue of the rats were tested with immunohistochemical methods and image analysis. RESULTS: On the third day of wound healing, collagen I of the rats in both Shengji Huayu Recipe-treated group and Shengji Recipe-treated group was higher than that in the untreated group, and collagen I of the rats in Huayu Recipe-treated group was lower than that in the untreated group (P<0.05). Collagen III of the rats in the three treated groups were lower than that in the untreated group (P<0.05). On the seventh day of wound healing, Collagen I of the rats in both Shengji Huayu Recipe-treated group and Shengji Recipe-treated group was higher than that in the untreated group (P<0.05), and collagen III of the rats in both Shengji Recipe-treated group and Huayu Recipe-treated group was higher than that in the untreated group (P<0.05). CONCLUSION: Resolving stagnation and promoting granulation therapy can promote the wound healing in rats.

Objective To discuss the diagnostic value of monochromatic energy image spectral CT in active small bowel bleeding and to screen the optimal energy level that indicates active bleeding of the gastrointestinal tract.Methods The bleeding model was established using the small intestines of pigs in vitro.Seven blood flow rates were simulated:0.500,0.400,0.300,0.200,0.100,0.050,0.025 ml/min,respectively.For each rate,a GE Discovery HD750 CT scanner was used in GSI scan mode and 64 slice CT was performed,with a delay of 15 s and 40 s simulated the arterial phase and portal venous phase,respectively.Each out of the blood flow rate in the 2 modes was respectively scanned 5 times.The GSI reconstruction platform was employed to obtain 7 monochromatic energy images(40,50,60,70,80,90,100 keV).A set of polychromatic energy images was obtained from an ordinary scan.The detection rates of the contrast agent exudation regions using the two scanning methods were compared.The contrast to noise ratios(CNR) for the contrast agent exudation regions were measured.Randomized block analysis of Variance was performed to compare the differences in CNR between energy levels.The x2 test was used to compare the detection rates obtained from the 2 scanning methods.Results The detection rates for energy spectral CT and 64 slice CT in the arterial phase were 31/35 and 23/35,respectively; there was significant difference(x2=5.185,P=0.023).The total detection rates of portal venous phase were 35/35 and 32/35,respectively,there was no significant difference(x2=l.393,P=0.238).On the ordinary scan mode,the detection rates of arterial and portal venous phase difference was statistically significant(x2 =6.873,P =0.009);but on the GSI scan mode,there was no significant difference(x2=2.386,P=0.122). The CNR values at 8 group energy levels for arterial phase and portal venous phase were statistically different(respectively P< 0.05),the CNR value of the contrast agent exudation regions at 50 keV and 60 keV monochromatic energy images on the GSI scan mode higher than that of polychromatic energy images,the difference was statistically significant(respectively P<0.05),the CNR in portal venous phase images were higher than that of arterial at all energy groups,differences were statistically significant(t=-3.996 to-2.380,respectively P< 0.05).Conclusions Monochromatic energy image spectral CT demonstrates superiority over polychromatic energy images in detecting active bleeding of the gastrointestinal tract.The optimal monochromatic energy value for detection was between 50 keV and 60 keV,and the detection was easier in the portal venous phase than in the arterial phase.
