ABSTRACT
With the advancement and development of life science and technology,many problems in liver surgery have been solved,and the surgical procedures of liver surgery have been continuously developed and the indications for surgery have been continuously expanded.Benign and malignant lesions and even donor liver can be performed under laparoscopy.The indications for laparoscopic liver resection are expanding,from superficial liver resection to a wider range of anatomical resection.At the same time of technological advancement,along with the development of the humanistic spirit,liver resection is not only the removal of lesions,but the pursuit of rehabilitation,which is "the best rehabilitation with minimal trauma".Laparoscopic liver resection has been greatly developed due to the spread of the concept of "precise medicine".
ABSTRACT
Objective To explore the feasibility and therapeutic effect of total laparoscopic hepatectomy(LH) for treating hepa‐tolithiasis .Methods 75 consecutive patients with hepatolithiasis operatively treated in our hospital from November 2003 to Novem‐ber 2012 were retrospectively analyzed .Among them ,35 cases underwent laparoscopic hepatectomy(LH group) and 40 cases under‐went open hepatectomies(OH group) .The operative modes in the two groups included the left liver lateral lobe resection ,left hemi‐hepatecomy ,common bile duct incision exploration ,choledochoscopy exploration for calculi extraction ,T tube drainage and cholecys‐tectomy .The clinical indicators including the operation time ,intraoperative blood loss ,analgesic drug use situation ,ambulation time , diet recovery time ,postoperative complication rate ,postoperative hospital stay time ,stone clearance rate and recurrence rate were analyzed and compared between the two groups .Results The operation time of the LH group was longer than that of the OH group[(205 .0 ± 40 .9) min vs .(155 .0 ± 26 .6) min ,P 0 .05) .The use rate of analge‐sic drugs in the LH group was lower than that of the OH group (0 vs .62 .5% ) .The ambulation time and the diet recovery time in the LH group were shorter than those in the OH group[(1 .5 ± 0 .5)d vs .(3 .6 ± 0 .7)d ,P 0 .05) .Conclusion LH combined with choledochoscopy for treating hepatolithiasis is feasible and safe in the patients conforming to the selected standard with an e‐qual therapeutic effect to that of open hepatectomy .LH has the advanteages of minimally invasive surgery such as small incision , less pain ,fast recovery ,less complications ,etc .
ABSTRACT
Objective To determine the safety and feasibility of laparoscopic dissection of hepatic pedicle in liver resections.Methods Laparoscopic dissection of hepatic pedicle was performed to achieve selective hepatic vascular inflow occlusion during anatomical hepatectomies in 43 patients with liver lesions.The average age was (46.1 ± 3.5) years.The hepatic pedicle was dissected precisely with sharp and blunt dissections to expose the portal vein,hepatic artery,and their branches.The hepatic ischemic area was judged after selective hepatic vascular inflow occlusion and the liver lesions were then resected.Results All 43 patients received anatomical hepatectomies successfully using the technique of laparoscopic hepatic pedicle dissection for selective hepatic vascular inflow occlusion.The mean operative time was (63.6 ± 11.2)minutes.The average blood loss was (243.8 ± 35.5)ml,and the mean hospital stay was (7.1 ± 1.6) days.Conclusion Laparoscopic dissection of hepatic pedicle in liver resection was feasible and safe.
ABSTRACT
Objective To compare the feasibility and safety of laparoscopic versus open hepatectomy.Methods The data of 165 patients who underwent laparoscopic hepatectomy were compared with 170 patients who underwent open hepatectomy in our hospital from November 2002 to December 2010.Results Laparoscopic hepatectomy was successfully carried out in 159 patients and 6 patients were converted to open operation because of intra-operative hemorrhage.The 170 patients in the open operative group had open hepatectomy successfully carried out.The hospital stay and cost in the laparoscopic group(7.6±1.3 d,31767.4±220.1(￥))were less than the open operation group(14.6±3.3 d,35127.3±392.2(￥))(t=-12.657,P＜0.001; t=-78.859,P＜0.001).There was no significant difference in Pringle's manoeuvre time,blood loss and postoperative complications(20.6 ±8.5vs.18.6±6.5 min,t=2.108,P=0.068),(420.8±76.5 vs.395.9±96.1 ml,t=2.157,P=0.063),(0 vs.4 cases,t=2.011,P=0.156))between the 2 groups.The operative time in the laparoscopic group was significantly longer than the open group(59.6 ± 12.2 vs.42.7 ± 22.6 min)(t=6.941,P＜0.001).Conclusions Laparoscopic hepatectomy is feasible and safe.It has the advantages of having less trauma and quicker recovery for tumors which were located superficially in the left liver and in the inferior part of the right liver.The operative time was longer than open hepatectomy,but there was no significant difference between the 2 groups in Pringle's manoeuvre time,blood loss and postoperative complications.The hospital stay and total hospital cost in the open operation group were higher than the laparoscopic hepatectomy group.
ABSTRACT
Objective To study the feasibility and safety of laparoscopic anatomical liver lobectomy for liver tumor. Methods The feasibility and therapeutic effect of laparoscopic anatomical liver resection on 67 patients were analyzed in our hospital from January 2005 to February 2010. Results Laparoscopic anatomical liver lobectomy was carried out successfully on all the patients. The operative time was 50.6± 16.2 min and the blood loss was 220. 8±76.5 ml. We did not use Pringle's manoeuvre. There was no postoperative complication. The patients were able to be ambulated out of bed within 24 hours and they started to take in food 1-3 days after surgery. The mean hospital stay was 5-7 days after surgery (mean 6.6±1.1 d). The total hospital cost was 30767.4±150. 1 Yuan. Conclusions Laparoscopic anatomical liver resection is feasible and safe. It has the advantages of minimal trauma and quick recovery for tumors located superficially, in the left liver, and in the inferior part of the right liver. Clinically, it should be used more widely.
