Abstract
Benign liver tumors are being detected more frequently due to the widespread use of ultrasound and complementary methods and due to improvements in diagnostic accuracy. In the case of a reliable diagnosis of asymptomatic hemangioma or focal nodular hyperplasia surgery is not indicated. Hepatic adenoma of considerable size should be resected primarily based on the risk of rupture. Improvements in diagnostic imaging as well as the optimization of surgical procedures with extremely low complication rates permit an individualized management strategy founded on evidence-based algorithms. In the case of an equivocal diagnosis, we advocate low-risk tumor resection instead of tumor biopsy due to the inherent complication rates of hemorrhage or tumor-cell dissemination and possible misleading histology.

Abstract
Focal nodular hyperplasia (FNH) is the second most common benign lesion of the liver and a common differential in the workup of solid liver lesions. With increasing use of modern imaging modalities FNH is becoming clinically more relevant. We present a case of pedunculated FNH presenting as a pericholecystic mass. This was resected laparoscopically due to persistent symptoms and uncertainty in diagnosis. We summarize the current literature with regard to the diagnosis, etiology, and management of FNH lesions.

Abstract
OBJECTIVE To evaluate our experience with more than 500 minimally invasive hepatic procedures. SUMMARY BACKGROUND DATA Recent data have confirmed the safety and efficacy of minimally invasive liver surgery. Despite these reports, no programmatic approach to minimally invasive liver surgery has been proposed. METHODS We retrospectively reviewed all patients who underwent a minimally invasive procedure for the management of hepatic tumors between January 2001 and April 2008. Patients were divided into 3 groups: laparoscopy with intraoperative ultrasound and biopsy only, laparoscopic radiofrequency ablation (RFA), and minimally invasive resection. To compare the various forms of surgery, we analyzed the incidence of complications, tumor recurrence, mortality, and cost. Statistical analysis was performed using chi(2) analysis, Student t test, Kaplan-Meier survival analysis with the log-rank test, and multivariable Cox models. RESULTS A total of 590 minimally invasive hepatic procedures were performed during 489 operative interventions. The representative tumor histologies were: hepatocellular carcinoma (HCC; N = 210), colorectal carcinoma (N = 40), miscellaneous liver metastases (N = 42), biliary cancer (N = 20), and benign tumors (N = 176). Thirty-five patients underwent laparoscopic ultrasound and confirmatory biopsy alone; 201 patients underwent 240 laparoscopic RFAs, and 253 patients underwent 306 minimally invasive resections. Conversion rates to open surgery for the RFA and resection group were 2% overall. One hundred ninety-nine (40.6%) patients were cirrhotic; 31 resections were performed in cirrhotic patients. Complication and mortality rates for RFA and resection were comparable (11% vs. 16%, and 1.5% vs. 1.6%). However, complication rates (14% vs. 29%; P = 0.02) and mortality (0.3% vs. 9.7%; P = 0.006) rates were higher in the cirrhotic versus noncirrhotic resection group. Overall recurrence rates for RFA and resection groups were 24% and 23%, respectively. Local recurrence rates were higher in the RFA group (6.3% versus 1.5%; P < 0.06). Overall patient survival differed between HCC patients receiving RFA alone and those receiving RFA and OLT (P < 0.0001). Overall survival for cancer patients receiving RFA versus resection differed significantly when unadjusted for other covariates (P = 0.01), and remained marginally significant in a multivariable model (P = 0.056). CONCLUSIONS Minimally invasive hepatic surgery has become a viable alternative to open hepatic surgery. Our present data are equivalent or superior to those encountered in any large open series. Our experience with RFA confirms a low local recurrence rate and an excellent technique for bridging patients to transplantation. Morbidity and mortality rates for minimally invasive hepatic resections in cirrhotics, is similar to other reported open resection series. This series confirmed excellent interim survival rates after laparoscopic HR and superiority over RFA in the treatment of cancer, with significantly lower local tumor recurrence rate.

Abstract
BACKGROUND Hepatocellular adenoma (HA) is a rare benign tumor of the liver. Surgical resection is generally indicated to reduce risks of hemorrhage and malignant transformation. We sought to evaluate clinical presentation, surgical management, and outcomes of patients with HA at our institution. METHODS We performed a retrospective review of 41 patients who underwent surgical resection for HA between 1988 and 2007. RESULTS Thirty-eight patients were women, and the median age at presentation was 36 years (range, 19-65 years). The most common clinical presentation was abdominal pain (70%) followed by incidental radiological finding (17%). Twenty-two patients had a history of oral contraceptive use. Median number of HA was one (range, 1-3). There were 32 open cases (3 trisectionectomy, 15 hemihepatectomy, 7 sectionectomy, 4 segmentectomy, and 3 wedge resection), and 9 laparoscopic cases (1 hemihepatectomy, 5 sectionectomy, 1 segmentectomy, and 2 wedge resection). The median estimated blood loss was 225 mL (range, 0-3400 mL). The median length of stay was 6 days (range, 1-15 days). Surgical morbidities included pleural effusion requiring percutaneous drainage (n = 2), pneumonia (n = 1), and wound infection (n = 1). There was no perioperative mortality. Twelve patients had hemorrhage from HA. Hepatocellular carcinoma was observed in two patients with HA. Median follow-up was 23 months (range, 1-194 months), at which time all patients were alive. CONCLUSION In view of 29% hemorrhagic and 5% malignant complication rates, we recommend surgical resection over observation if patient comorbidities and anatomic location of HA are favorable. A laparoscopic approach can be safely used in selected cases.

Abstract
BACKGROUND Laparoscopic surgery has gained growing acceptance, but this does not hold for laparoscopic surgery of the liver, above all for patients with hepatocellular carcinoma (HCC) and cirrhosis. This approach mainly includes diagnostic procedures and interstitial therapies. However, we believe there is room for laparoscopic liver resections in well-selected cases. The aim of this study is to assess: (a) the risk of intraoperative bleeding and postoperative complications, (b) the safety and the respect of oncological criteria, and (c) the potential benefit of laparoscopic ultrasound in guiding liver resection. METHODS A prospective study of laparoscopic liver resections for hepatocellular carcinoma was undertaken in patients with compensated cirrhosis. Hepatic involvement had to be limited and located in the left or peripheral right segments (segments 2-6), and the tumor had to be 5 cm or smaller. Tumor location and its transection margins were defined by laparoscopic ultrasound. RESULTS From January 1997, 22 out of 250 patients with HCC (9%) underwent laparoscopic liver resections. The mean patient age was 61.4 years (range, 50-79 years). In three patients, conversion to laparotomy was necessary. The laparoscopic resections included five bisegmentectoies (2 and 3), nine segmentectomies, two subsegmentectomies and three nonanatomical resections for extrahepatic growing lesions. The mean operative time, including laparoscopic ultrasonography, was 199 +/- 69 min (median, 220; range, 80-300). Perioperative blood loss was 183 +/- 72 ml (median, 160; range, 80-400 ml). There was no mortality. Postoperative complications occurred in two out of 19 patients: an abdominal wall hematoma occurred in one patient and a bleeding from a trocar access in the other patient requiring a laparoscopic re-exploration. Mean hospital stay of the whole series was 6.5 +/- 4.3 days (median, 5; range, 4-25), while the mean hospital stay of the 19 laparoscopic patients was 5.4 +/- 1 (median, 5; range, 4-8). CONCLUSION Laparoscopic treatment should be considered in selected patients with HCC and liver cirrhosis in the left lobe or segments 5 and 6 of the liver. It is clear that certain types of laparoscopic resection are feasible and safe when carried out by adequately skilled surgeons with appropriate instruments.

Abstract
INTRODUCTION Literature-based data on mortality after hepatectomy may be misleading, as poor outcomes are less likely to be published. The objective of the current study was to compare published vs public, nationally available mortality rates after hepatic resection. MATERIALS AND METHODS A systematic MEDLINE review was conducted to identify reports of hepatectomy outcome between January 1998-December 2004. Data were analyzed to calculate literature-based mortality rate and then compared with population-based mortality rate for hepatectomy using the Nationwide Inpatient Sample (NIS) dataset. RESULTS Twenty-three publications fulfilled screening criteria. The studies included 7,073 patients who had undergone hepatic resection (46.1% within USA vs 53.9% outside USA). Most patients were male (58.6%) with median age of 56 years. Indications for hepatic resection included hepatocellular carcinoma (47.7%), metastatic disease (34.3%), or other (18.1%). Cirrhosis was present in 23.2% of patients; 46.9% patients underwent either a hemi-hepatectomy or extended resection. The literature-based mortality rate was 3.6% (US centers only, 2.8%). Analysis of NIS revealed 11,429 hepatectomy cases. After controlling for gender, age, extent of hepatectomy, hepatocellular cancer diagnosis, and presence of cirrhosis, the adjusted NIS-based perioperative mortality rate for hepatectomy was 5.6% (95% CI, 5.0-6.2%). The relative mortality after hepatectomy was 1.6-fold higher based on population-based data compared with reports from the literature (P<0.05). CONCLUSION Actual population-based mortality rates for major liver resections may be higher than those reported in the literature. Informed consent should reflect actual local and national mortality rates rather than selective reports from the literature.

Abstract
BACKGROUND Careful control of haemostasis is particularly important in laparoscopic hepatic surgery, since a bloodless operative field results in safer and smoother procedures. A selective vascular control for a left lateral segmentectomy may be facilitated by the use of three-dimensional (3D) virtual reality. MATERIALS AND METHODS A 67-year-old male patient presenting with a 3.5-cm hepatocellular carcinoma (HCC) located between segment II and III of the liver was referred for hepatic resection. Transplant was contraindicated due to previous head and neck cancer surgery. Preoperative 3D reconstruction was used for preoperative planning and allowed a virtual resection to be done as well as peroperative simulation. RESULTS Five ports were used. The first step was primary control of the hepatic pedicle. 3D virtual-reality reconstruction demonstrated the position of the tumor in the segment and regarding the vessels. The left hepatic artery and the portal vein were successively dissected and controlled. The real anatomy was compared to the virtual-reality reconstruction. Both demonstrated the same anatomy. Vascular section was completed and this resulted in a typical color change of the left lateral segment as well as a small decrease in size. The bisegmentectomy was performed using harmonic dissectors (Autosonix(R), Tyco Healthcare), bipolar cautery, clips, and application of Endo GIA vascular staples (Tyco Healthcare) on the portal pedicles. The procedure was completed following isolation and control of the left hepatic vein. After section, the specimen was placed in a bag and extracted following enlargement of the camera port. Follow-up was uneventful and there was no elevation of hepatic enzymes or postoperative ascites. The patient left the hospital on the fifth postoperative day. CONCLUSION 3D reconstruction allowed the procedure to be simulated preoperatively. This facilitated the intraoperative identification of the vascular anatomy and the control of the left lateral segment arteries and veins, thus preventing intraoperative bleeding. The use of this approach in preoperative planning is recommended.

Abstract
BACKGROUND The best type of laparoscopic approach in solid liver tumours (SLTs), whether total laparoscopic surgery or hand-assisted laparoscopic surgery (HALS), has not yet been established. Our objective is to present our experience with laparoscopic liver resections in SLTs performed by HALS using a new approach. METHODS We performed 35 laparoscopic resections in SLTs, of which 26 were carried out using HALS (in 25 patients) and 21 patients had liver metastases of a colorectal origin (LMCRC) (1 patient had 2 resections), 1 metastasis from a neuroendocrine tumour of the pancreas, 1 hepatocarcinoma on a healthy liver, 1 primary hepatic leiomyosarcoma and 1 giant haemangioma. Mean follow-up was 22 months. OPERATION: One right hemihepatectomy, one left hemihepatectomy, five bisegmentectomies II-III, three bisegmentectomies VI-VII and 16 segmentectomies (five of S. VI, three of S. VIII; three of S. V; two of S. IVb; one of S. II; one of S. IV; and in the remaining case resection of S. III and VI plus resection of a metastasis in S. VIII). MAIN OUTCOME MEASURES Morbidity and mortality, conversion to open procedure, intraoperative blood loss, intra- and postoperative transfusion, length of stay and survival. RESULTS There were no intra- or postoperative deaths, nor were there any conversions. One patient presented with morbidity (3.8%) (liver abscess). Mean blood loss was 200 ml (range 0-600 ml). One patient required transfusion (3.8%). Mean operative time was 180 min (range 120-360 min). Mean length of hospital stay was 4 days (range 2-5 days). The actuarial survival rate of the patients at 36 months with liver metastases from colorectal carcinoma (LMCRC) was 80%. CONCLUSIONS Liver resection with HALS reproduces the low morbidity and mortality rates and effectiveness (3-year survival) of open surgery in SLTs when indicated selectively.

Abstract
AIM: To investigate the possibilities and advantages of laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration of the common bile duct compared with traditional open operation.
METHODS: Laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration of the common bile duct and traditional open operation were performed in two groups of patients who had gallstones in the left lobe of liver and in the common bile duct. The hospitalization time, hospitalization costs, operation time, operative complications and post-operative liver functions of the two groups of patients were studied.
RESULTS: The operation time and post-operative liver functions of the two groups of patients had no significant differences, while the hospitalization time, hospitalization costs and operative complications of the laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration in the common bile duct group were significantly lower than those in the traditional open operation group.
CONCLUSION: For patients with gallstones in the left lobe of liver and in the common bile duct, laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration of the common bile duct can significantly shorten the hospitalization time, reduce the hospitalization costs and the post-operative complications,without prolonging the operation time and bringing about more liver function damages compared with traditional open operation. This kind of operation has more advantages than traditional open operation.

Abstract
HYPOTHESIS Laparoscopic liver surgery is significantly limited by the technical difficulty encountered during transection of substantial liver parenchyma, with intraoperative bleeding and bile leaks. This study tested whether the use of a bioabsorble staple line reinforcement material would improve outcome during stapled laparoscopic left lateral liver resection in a porcine model. STUDY DESIGN A total of 20 female pigs underwent stapled laparoscopic left lateral liver resection. In group A (n = 10), the stapling devices were buttressed with a bioabsorbable staple line reinforcement material. In group B (n = 10), standard laparoscopic staplers were used. Operative data and perioperative complications were recorded. Necropsy studies and histopathological analysis were performed at 6 weeks. Data were compared between groups with the Student's t-test or the chi-square test. RESULTS Operating time was similar in the two groups (64 +/- 11 min in group A versus 68 +/- 9 min in group B, p = ns). Intraoperative blood loss was significantly higher in group B (185 +/- 9 mL versus 25 +/- 5 mL, p < 0.05). There was no mortality. There was no morbidity in the 6-week follow-up period; however, two animals in group B had subphrenic bilomas (20%) at necropsy. At necropsy, methylene blue injection via the main bile duct revealed leakage from the biliary tree in four animals in group B and none in group A (p < 0.05). Histopathological examination of the resection site revealed minor abnormalities in group A while animals in group B demonstrated marked fibrotic changes and damaged vascular and biliary endothelium. CONCLUSION Use of a bioabsorbable staple line reinforcement material reduces intraoperative bleeding and perioperative bile leaks during stapled laparoscopic left lateral liver resection in a porcine model.

Abstract
This systematic review was undertaken to assess the published evidence for the safety, feasibility and reproducibility of laparoscopic liver resection. A computerized search of the Medline and Embase databases identified 28 non-duplicated studies including 703 patients in whom laparoscopic hepatectomy was attempted. Pooled data were examined for information on the patients, lesions, complications and outcome. The most common procedures were wedge resection (35.1%), segmentectomy (21.7%) and left lateral segmentectomy (20.9%). Formal right hepatectomy constituted less than 4% of the reported resections. The conversion and complication rates were 8.1% and 17.6%, respectively. The mortality rate over all these studies was 0.8% and the median (range) hospital stay 7.8 days (2-15.3 days). Eight case-control studies were analysed and although some identified significant reductions in-hospital stay, time to first ambulation after surgery and blood loss, none showed a reduction in complication or mortality rate for laparoscopically carried out resections. It is clear that certain types of laparoscopic resection are feasible and safe when carried out by appropriately skilled surgeons. Further work is needed to determine whether these conclusions can be generalized to include formal right hepatectomy.

Abstract
BACKGROUND Despite the advances during the last years, liver resection remains as one of the last frontiers in laparoscopic surgery. Published data include case reports and evaluations of small series of patients and are seen with skepticism by many surgeons. Laparoscopic liver resection is a long and hazardous and long procedure and experience in liver and laparoscopic surgery and an adequate equipment are needed. A critical analysis of the indications, technical aspects and the method was performed. CONCLUSIONS We can conclude that laparoscopic liver resection is safe, feasible and can be considered as an excellent choice for selected cases. There is no doubt that video-laparoscopic liver resection is a reality and should be part of liver surgeon's therapeutic armamentarium.

Abstract
The expanding use of ultrasound in general practice is leading to an ever increasing rate of detection of true hepatic incidentaloma. The correct diagnosis of hepatic incidentaloma may be made in over 90% with non-invasive means. The questionable diagnosis of "symptomatic" incidentaloma should undergo close scrutiny prior to a decision in favour of surgery. With regard to more recent literature, the former "absolute" requirement for surgical resection in all cases of liver cell adenoma may have to be reappraised. Final inability to rule out malignancy represents an unquestionable indication for surgery in the light of low rates of morbidity and lack of mortality in this otherwise healthy patient group. Percutaneous biopsies should not be performed due to oncological hazards, indeterminate results and potential for acute complications.The stage-oriented radical re-resection following diagnosis of an incidentally detected gallbladder cancer may lead to significantly improved long-term survival, especially in the early tumour stages T1b and T2, which represents the most common stage of gallbladder cancer in incidentaloma. Patients at elevated risk for incidental gallbladder cancer should undergo thorough instruction with regard to the potential hazards of laparoscopic cholecystectomy. Multimodal therapeutic strategies directed at advanced stages of incidentally detected gallbladder cancer should be evaluated in prospective multicentre studies.

Totally laparoscopic right hepatectomy. Am J Surg 2007; 194:685-9. [PMID: 17936436 DOI: 10.1016/j.amjsurg.2006.11.044] [Citation(s) in RCA: 164] [Impact Index Per Article: 9.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2006] [Revised: 11/14/2006] [Accepted: 11/15/2006] [Indexed: 02/07/2023]
Abstract
BACKGROUND Since the first laparoscopic cholecystectomy was performed in 1987, the surgical applications of laparoscopy have grown to involve most areas of general surgery. Until recently, however, major liver surgery remained outside of the scope of minimally invasive surgery. Building on advances in laparoscopic equipment, techniques, and ongoing experience in hepatic surgery, major liver resection has been performed laparoscopically in some select centers. At our institute, a safe and standardized approach to minimally invasive major hepatectomy has been developed. This article illustrates the relevant technical maneuvers in the performance of a totally laparoscopic right hepatectomy. Common pitfalls and areas of concern are discussed. METHODS A detailed description of a standardized procedure is presented. The technique was developed from a single-institution experience of 41 laparoscopic right hepatectomies performed in a tertiary care referral center for laparoscopic digestive surgery. The prevention of bleeding and gas embolism are discussed. CONCLUSIONS The laparoscopic right hepatectomy is feasible and safe if the appropriate expertise and equipment are available. In selected patients, this new approach can be proposed by a surgeon experienced in laparoscopic and hepatic surgery as an alternative to conventional open liver resection.

Abstract
The development of new ultrasound (US) contrast agents and sonographic techniques has considerably improved the possibilities of ultrasound in the assessment of liver tumors. An overview is given on diagnostic potential of contrast-enhanced US (CEUS) and real-time low mechanical index technique in the detection of various focal liver lesions compared with computed tomography, magnetic resonance imaging or intraoperative US. In two of our own studies that included 100 patients each we showed an increase of correct findings in CEUS compared with B-mode US from 64% to 87% and from 67% to 84% as confirmed by intraoperative evaluation of the liver. Especially after chemotherapy and in the case of small metastases, significantly more metastases were correctly detected by CEUS compared with B-mode US. These results and clinical study results in the literature show that CEUS allows tumor detection and direct visualization of the tumor vascularity and put contrast-enhanced sonography among recommended noninvasive imaging methods for focal liver lesions with improvements in diagnostic strategy.

Abstract
BACKGROUND/AIMS To report our experience with laparoscopic treatment of liver tumors during right-sided transperitoneal laparoscopic nephrectomy. METHODS Two patients undergoing transperitoneal laparoscopic radical nephrectomy on the right side each had a concomitant tumor in the right lobe of the liver. The first patient was incidentally found to have a lesion suspicious for metastatic disease. The second had a known asymptomatic giant hemangioma of the liver. RESULTS Total operative time was 130 and 101 min. Estimated blood loss was 400 and 300 ml. There were no complications. The first patient had bilateral papillary renal cell carcinoma and concomitant fibroadipose tissue within the liver. The second patient presented with clear cell carcinoma of the right kidney and a cavernous hemangioma of the liver. CONCLUSIONS When indicated, simultaneous right-sided kidney and liver tumors may be treated by a combined laparoscopic transperitoneal approach. Laparoscopic expertise is advised.

Abstract
BACKGROUND Laparoscopic liver resection (LLR) has gained wide acceptance for various liver resection procedures, mainly for benign diseases. However, only small series have been reported from a few selected centers. METHODS Between January 2001 and January 2006, a total of 629 liver resections were performed at our institution. The indication was solid benign liver tumor in 56 (8.9%) patients. LLR was performed in 20 (35.7%) cases. Data from the LLR group were compared with those from a consecutive control group undergoing open liver surgery (OS) for similar indications in a matched-pair analysis during the same period. The pairs were matched as closely as possible for age, gender, American Society of Anesthesiologists (ASA) score, indication for resection, and type and location of the lesions. The endpoint was to investigate overall morbidity and outcome. RESULTS All patients but one are alive and well after a mean follow-up of 35 months (range 10-60 months). Conversion laparotomy was required in two out of 20 (10%) cases for uncontrolled bleeding (one requiring temporary hemodialysis). LLR was characterized by faster time to first oral intake and shorter hospital stay compared to OS (p = 0.001 and 0.008, respectively). Incisional hernias (25%) were only recorded in the OS (p = 0.047 vs. LLR). Overall morbidity was 45% in OS versus 20% in LLR (p = 0.3). CONCLUSIONS LLR significantly reduced time to oral intake, hospital stay, and incisional hernias compared to OS. Bleeding is a major risk and should be carefully considered when resecting benign tumors. In the hands of expert surgeons, LLR may become the gold standard for the resection of benign liver tumors located in the anterior and lateral sectors and for minor hepatic resections.

Abstract
BACKGROUND Liver surgery, especially for cirrhotic patients, is one of the last areas of resistance to progress in laparoscopic surgery. This study compares the postoperative results and the 2-year patient outcomes between laparoscopic and open resection for hepatocellular carcinoma in patients with histologically proven cirrhosis. METHODS From May 2000 to October 2004, 23 consecutive cirrhotic patients who underwent laparoscopic hepatectomy (LH) for HCC were compared in a retrospective analysis with a historic group of 23 patients who underwent open hepatectomy (OH). The two groups were well matched for age, gender, American Society of Anesthesiology (ASA) class, tumor location and size, type of liver resection, and severity of cirrhosis. The selection criteria for both groups specified a small (size < 5 cm), exophytic, or subcapsular tumor located in the left or peripheral right segments of the liver (II-VI segments, Couinaud); a well-compensated cirrhosis (Child-Pugh A); and an ASA score lower than 3. In the LH group, 15 subsegmentectomies, 3 segmentectomies, and 5 left lateral sectionectomies were performed, as compared with 12 subsegmentectomies, 5 segmentectomies, and 6 left lateral sectionectomies in the OH group. RESULTS One patient in the LH group (4.3%) underwent conversion to laparotomy for inadequate exposition. The mean operative time was statistically longer for the LH group (LH, 148 min; OH, 125 min; p = 0.016), whereas blood transfusions (LH, 0%; OH, 17.3%; p = 0.036), Pringle maneuver (LH, 0%; OH, 21.73%; p = 0.017), mean hospital stay (LH, 8.3 days; OH, 12 days; p = 0.047), and postoperative complications (LH, 13%; OH, 47.8%; p = 0.010) were significantly greater in OH group. There was no statistically significant difference in mortality and 2-year survival rates between the two groups. CONCLUSION This study shows that LH for HCC in properly selected cirrhotic patients results in fewer early postoperative complications and a shorter hospital stay than the traditional OH. The 2-year survival rate was the same for LH and OH.

Abstract
BACKGROUND There is a growing interest in using laparoscopy for hepatic resection. However, structured training is lacking in part because of the lack of an ideal animal training model. We sought to identify an animal model whose liver anatomy significantly resembled that of the human liver and to assess the feasibility of learning laparoscopic hepatic inflow and outflow dissection and parenchyma transection on this model. METHODS The inflow and outflow structures of the sheep liver were demonstrated via surgical dissection and contrast studies. Laparoscopic left major hepatic resections were performed. RESULTS The portal hepatis of all 12 sheep (8 for anatomic study and 4 for laparoscopic hepatic resection) resembled that of human livers. The portal vein (PV) was located posteriorly; the common hepatic artery (CHA) and the common bile duct (CBD) were located anterior medially and anterior laterally with respect to the portal hepatis. The main PV bifurcated into a short right and a long left PV. The extrahepatic right PV then bifurcated into right posterior and anterior sectoral PV. The CBD and CHA bifurcated into left and right systems. The cystic duct originated from the right hepatic duct. The cystic artery originated from the right HA in 11/12 animals. The left hepatic vein drained directly into the inferior vena cava (IVC). The middle and the right hepatic veins formed a short common channel before entering the IVC. Multiple venous tributaries drained directly into IVC. Familiarity with sheep liver anatomy allowed laparoscopic left hepatic lobe (left medial and lateral segments) resection to be performed with accuracy and preservation of the middle hepatic vein. CONCLUSIONS The surgical anatomy of sheep liver resembled that of human liver. Laparoscopic major hepatic resection can be performed with accuracy using this information. Sheep is therefore an ideal animal model for advanced surgical training in laparoscopic hepatic resection.

Abstract
This article summarizes findings about the applicability of minimal-access techniques for thoracic and upper gastrointestinal cancers, including those affecting the lung, liver, stomach, and adrenal gland. If metastasectomy and cytoreductive surgery are rapidly evolving, minimal-access surgery in this setting is in its introductory stages. Nevertheless, minimal-access metastasectomy and cytoreductive surgery harbor great potential for selected patients, but further clinical studies are needed.

Abstract
BACKGROUND In recent years, laparascopic techniques have become a more widely used and accepted means for performing various types of liver resections. In this report, the authors describe the use and initial applications of a new approach to laparoscopic liver resection using vapor pulse coagulation. METHODS Liver resections using vapor plasma coagulation technology were performed for 11 patients at the authors' center. Candidates were initially selected because they had benign disease and lesions amenable to standard resections along anatomic planes. Four resections were performed with a hand-assist technique and seven without it. RESULTS All the patients faired well. The length of the hospital stay was 3.4 +/- 0.7 days. There were no major surgical complications, bile leaks, or reoperations. None of the patients required blood transfusions. One patient was readmitted for fever and urinary tract infection, and one patient had 1 week of right leg swelling attributable to the use of stirrups. CONCLUSIONS Vapor plasma coagulation using a laparoscopic approach for hepatic resection is a promising new technology that deserves further exploration.

Abstract
Laparoscopy for the resection of liver masses in children has remained undeveloped despite the wide acceptance of laparoscopy in the field of pediatric surgery. The authors report a case of nonanatomical laparoscopic hepatic resection of a large mesenchymal hamartoma in a 2-year-old boy. The procedure was performed using an innovative approach with a combination of different technologies that allowed for a safe and precise resection. This case demonstrates the feasibility of a nonanatomical laparoscopic hepatic resection, even for very large tumors. Both technical expertise and use of novel technologies are necessary to ensure a precise and controlled resection.

Abstract
UNLABELLED Differentiation of small and atypical hemangiomas from other hepatic masses using imaging methods can be difficult, especially in patients with underlying malignant disease. Therefore, contrast-enhanced ultrasound was assessed in patients with histologically confirmed hemangiomas with respect to contrast-enhancing kinetics and tumor characteristics. In 58 patients with indeterminate hepatic lesions demonstrated with at least 2 imaging methods (ultrasound/computed tomography/magnetic resonance imaging), ultrasound-guided liver biopsy revealed hemangioma. In all patients a hepatic neoplasm had been suspected because of underlying malignant disease (n=41), liver cirrhosis (n=15), or growth of the lesion (n=2). All patients underwent nonlinear, low mechanical index real-time contrast-enhanced ultrasound scanning with bolus injections of SonoVue. Peripheral nodular arterial enhancement was detected in 43 patients (74%), whereas the typical metastatic peripheral rim-like enhancement was not observed at all. Strong homogenous arterial enhancement was found in 9 of 58 (16%) patients. In 6 patients (10%), the arterial contrast enhancement pattern could not be determined because of the very small size of the lesions or fibrotic nodules. Forty-five (78%) of the hemangiomas showed homogenous centripetal filling within 180 seconds. CONCLUSION Contrast-enhanced ultrasound demonstrates typical hemangioma imaging characteristics, that is, peripheral nodular contrast enhancement and iris-diaphragm sign in a high percentage of patients with undetermined lesions. This technique may therefore improve noninvasive functional characterization and differentiation of hemangiomas.

Abstract
BACKGROUND Since 1997, the authors have performed laparoscopic left lateral sectionectomy of lesions of the liver in preference to open surgery. The aim of this study was to assess the outcome. METHODS Between October 1997 and March 2005, 36 laparoscopic left lateral sectionectomies were performed using five trocars and a small incision for specimen retrieval. Liver resection was performed mainly using a harmonic scalpel and staplers. The Pringle manoeuvre was used in 24 patients. RESULTS The mean patient age was 55.2 (range 31-80) years. Twelve patients had underlying cirrhosis. Surgery was performed for 20 malignant lesions and 16 benign lesions with a mean size of 42.7 (range 5-110) mm. Conversion to laparotomy occurred in one patient. The mean operating time was 171.5 (range 90-240) min. Operatiing time and use of the Pringle manoeuvre were significantly decreased in the second half of the series. Mean blood loss was 208 (range 50-600) ml. No transfusion was required. There were no deaths. Two patients had postoperative complications (one incisional hernia and one pneumonia). The median postoperative stay was 5.2 days. CONCLUSION The laparoscopic approach to left lateral sectionectomy was safe and feasible in this series and could be considered as a routine approach in selected patients.

Abstract
BACKGROUND Laparoscopy is slowly becoming an established technique for liver resection. This procedure still is limited to centers with experience in both hepatic and laparoscopic surgery. Preliminary reports include mainly minor resections for benign liver conditions and show some advantage in terms of postoperative recovery. The authors report their experience with laparoscopic liver resection, the evolution of the technique, and the results. METHODS From 1999 to 2006, 70 laparoscopic liver resections were performed using a procedure similar to resection by laparotomy. RESULTS There were 38 malignant tumors (54%) and 32 benign lesions (46%). The malignant tumors were mainly hepatocellular carcinomas (19 of 24 patients had cirrhosis). The tumor mean size was 3.8 +/- 1.9 cm (range, 2.2-8 cm). There were 19 major hepatectomies, 34 uni- or bisegmentomies, and 17 atypical resections. The operative time was 227 +/- 109 min. Conversion to laparotomy was required for seven patients (10%), mainly for continuous bleeding during transection. Nine patients (13%) required blood transfusion. One patient had both brisk bleeding and gas embolism from a tear in the section line of the right hepatic vein requiring laparoscopic suture. Blood loss and transfusion requirements were significantly lower in recent than in early cases and in resections with prior vascular control than in those without such control. Postoperative complications were experienced by 11 patients (16%), including one bleed from the hepatic stump requiring hemostasis and two subphrenic collections requiring percutaneous drainage. One cirrhotic patient died of liver failure after resection of a partially ruptured tumor. No ascites was observed in other cirrhotic patients. The mean hospital stay was 5.9 days. CONCLUSION The study results confirm that laparoscopic liver resection, including major hepatectomies, can be safely performed by laparoscopy.

Abstract
BACKGROUND Bleeding is a known and CO2 embolization a suggested risk factor for increased morbidity after laparoscopic liver resection. Devices for laparoscopic liver parenchymal transection must be evaluated for safety in this context. METHOD Twelve piglets underwent laparoscopic surgery during CO2 pneumoperitoneum, each animal receiving three 6 cm long transections into the liver parenchyma made with ultrasonic dissector, ultrasonic shears and vessel sealing system, respectively. Endpoints were bleeding, operation time and gas embolization. The transections and embolization events, evaluated with transesophageal echocardiography, were video recorded. Bleeding and embolization were also assessed on video tapes and operating time measured. Arterial blood gases were recorded on line. RESULTS The ultrasonic dissector was least advantageous in terms of bleeding and operation time. Gas embolization was more frequent with the vessel sealing system than with the ultrasonic dissector and ultrasonic shears. During two episodes of gas embolization, pCO2 increased and pO2 and pH decreased. CONCLUSIONS Use of all three devices is feasible. Bleeding and operation time are greatest with the ultrasonic dissector. Gas embolization occurs during transection, though in most instances it is completely harmless. Laparoscopic liver surgery with these techniques used may pose a risk of gas embolization with clinical implications. Monitoring for such events is probably to be recommended.

Abstract
BACKGROUND Benign liver tumours (haemangioma, focal nodular hyperplasia, and hepatic adenoma) have different prevalence and prognosis. Spontaneous rupture and malignant transformation can complicate hepatic adenoma. Elective surgery is controversial, and indications are represented by uncertain diagnosis, presence of symptoms, and prevention of major complications. OBJECTIVES To assess the beneficial and harmful effects of elective surgery of benign liver tumours. We identified 31 cases series. These were small (with less than 60 participants) and the types of tumours mixed. These studies reported no significant mortality, but in the six studies with mortality it ranged from 1% to 17%.

A further search included the proceedings of major hepatological and surgical congresses (Annual Meetings of the American Association for the Study of the Liver (AASLD) and European Association for the Study of the Liver (EASL)), and examination of the references of relevant papers and reference lists of the identified studies. SELECTION CRITERIA Randomised clinical trials in adult patients with benign liver tumours without indications for emergency surgery in which elective surgery (resection) versus no intervention or sham operation are compared. DATA COLLECTION AND ANALYSIS All trials identified through searches were evaluated for eligibility for inclusion. We intended to extract relevant data in order to analyse the outcomes as per our published protocol using intention-to-treat analysis. MAIN RESULTS We could not identify any randomised clinical trials. AUTHORS' CONCLUSIONS We were unable to find evidence supporting or refuting elective surgery for patients with benign liver tumours. We need large, long-term randomised clinical trials with adequate methodology to assess the benefits and harms of elective surgery.

Abstract
BACKGROUND The indications for intervention in cases of benign liver tumors include symptoms, suspicion of malignancy, or risk of malignant change. METHODS Eighty-four liver resections for benign tumors were performed in our hospital from June 1996 to December 2004. The patient records were reviewed retrospectively. RESULTS The study group (41 females, 43 males; average age, 41.4 +/- 10.5 y) included 46 cavernous hemangiomas, 27 focal nodular hyperplasias, 5 hepatic adenomas, and 6 liver cysts. The indications for resection were inability to rule out malignancy (50 [59.5%]), symptoms (33 [39.3%]), and others (1 [1.2%]). Postoperatively, 28 of the 33 patients had resolution of symptoms. Twenty-nine patients (34.5%) had chronic hepatitis B infection. CONCLUSIONS Liver resection for benign liver tumor is safe, but indications for intervention must be evaluated carefully. The presence of chronic parenchymal liver disease does not increase morbidity in these patients.

Abstract
Laparoscopic liver surgery has evolved rapidly over the past 5 years in a select number of centers. The growing experience with these procedures has resulted in a shift in the diagnostic and therapeutic approach to common liver tumors. The fact that resection of benign and malignant hepatic masses can now be accomplished laparoscopically with relatively low morbidity has influenced the decision-making process for physicians involved in the diagnosis and management of these lesions. For example, should a gastroenterologist or hepatologist seeing a 32-year-old woman with an asymptomatic 4 cm hepatic lesion that is radiologically indeterminate for adenoma or focal nodular hyperplasia (FNH): (1) continue to observe with annual computed tomography/magnetic resonance imaging (CT/MRI) scans, (2) subject the patient to a liver biopsy, or (3) refer for laparoscopic resection? For a solitary malignant liver tumor in the left lateral segment, should laparoscopic resection be considered the new standard of care, assuming the surgeon can perform the operation safely? We present current data and representative case studies on the use of laparoscopic liver resection at 2 major medical centers in the United States. We propose that surgical engagement defined by the managing physician's decision to proceed with a surgical intervention is increasingly affected by the availability of, and experience with, laparoscopic liver resection.

Abstract
A 57-year-old man presented with a liver mass that had been detected on physical examination. The abdominal computed tomography scan revealed a 5-cm single nodular hepatoma located in segments 6 and 7. A total laparoscopic right posterior sectionectomy was performed for this lesion. The anatomical demarcation of the posterior section was possible with selective control of a Glissonian pedicle to that section. The patient was discharged on postoperative day 13 without complications. The postoperative pathology confirmed a hepatocellular carcinoma with a 1-cm free resection margin. The patient had no evidence of recurrence at 12-month follow-up. To our knowledge, this is the first reported case of total laparoscopic right posterior sectionectomy in segments 6 and 7.

Abstract
BACKGROUND The use of radiofrequency (RF) energy has been described to perform open liver resection safely and with minimal blood loss. Yet no data are available on the potential contribution of RF energy to the limitation of intraoperative blood loss during laparoscopic liver resection (LLR). The aim of this prospective, nonrandomized study was to investigate the potential contribution of RF energy to the limitation of intraoperative blood loss in patients undergoing LLR. METHODS Forty-five patients [male/female ratio 22/23, age 57 years (26-80)] underwent LLR. Eleven benign and 47 malignant lesions (mostly colorectal metastases) were resected. Median number [1 (1-3)] and maximum diameter [40 mm (8-170)] of tumors as well as median tumor free margins [10 mm (1-30)] were comparable in patients undergoing LLR with (20 patients) or without (25 patients) RF-assistance. Thirty-eight minor (< or = 2 segments) and 9 major (> 3 segments) resections were performed. Eighteen patients simultaneously underwent additional surgery. RESULTS No mortality occurred. Median intraoperative blood loss was 200 (5-4000) ml and was similar in patients undergoing LLR with or without RF-assistance. The type of surgical procedure was a determinant for the amount of intraoperative blood loss (p = 0.0002). Significant bleeding occurred from large hepatic vessels at major resections. Median operation time was 115 (45-360) minutes. RF-assistance didn't seem to reduce perioperative morbidity. CONCLUSIONS LLR can be performed with minimal intraoperative blood loss, which is determined by the type of hepatectomy. Significant intraoperative bleeding occurs from large hepatic vessels during major resections. RF-assisted parenchymal transection in LLR doesn't seem to reduce blood loss, operation time, or perioperative morbidity.

Abstract
BACKGROUND Laparoscopic surgery has gained growing acceptance, but this does not hold for laparoscopic surgery of the liver. This mainly includes diagnostic procedures, interstitial therapies, and treatment of liver cysts. However, the authors believe there is room for a laparoscopic approach to the liver in selected cases. METHODS A prospective study of laparoscopic liver resections was undertaken with patients who had preoperative diagnoses of benign lesion and hepatocellular carcinoma with compensated cirrhosis. The inclusion criteria required that hepatic involvement be limited and located in the left or peripheral right segments (segments 2-6), and that the tumor be 5 cm or smaller. The location of the tumor and its transection margin were defined by laparoscopic ultrasound (LUS). RESULTS From December 1996, 17 (5%) of 313 liver resections were included in the study. There were 5 benign lesions and 12 hepatocellular carcinomas in cirrhotic patients. The mean age of the study patients was 59 years (range, 29-79 years). The LUS evaluation identified the presence of new hepatocellular carcinoma nodules in two patients (17%). The resections included 1 bisegmentectomy, 8 segmentectomies, 3 subsegmentectomies, and 3 nonanatomic resections. The mean operative time, including laparoscopic ultrasonography, was 156 +/- 50 min (median, 150 min; range, 60-250 min), and the perioperative blood loss was 190 +/- 97 ml. There was no mortality. Conversion to laparotomy was necessary for two patients. Postoperative complications were experienced by 3 of 15 patients, all of them cirrhotics. One of the patients had a wall hematoma, and the remaining two patients had bleeding from a trocar access requiring a laparoscopic reexploration. The mean hospital stay for the whole series was 6.9 +/- 4.9 days (median, 6 days; range, 2-25 days) and 5.6 +/-1.4 days (median, 6 days; range, 2-8 days) for the 15 laparoscopic patients. CONCLUSION Laparoscopic treatment should be considered for selected patients with benign and malignant lesions in the left lobe or frontal segments of the liver. Evaluation by LUS is indispensable to guarantee precise determination of the segmental tumor location and the relationship of the tumor to adjacent vascular or biliary structures, excluding adjacent or adjunctive new lesions. The evolution of laparoscopic hepatectomies probably will depend on the development of new techniques and instrumentations.

Abstract
A focal nodular hyperplasia (FNH) rarely requires surgical intervention unless complications or clinical symptoms come into play. In 2 female patients, ages 35 and 44, with symptomatic tumors of that entity (10 and 14 cm, respectively, in size) we performed a laparoscopic liver resection. Directly before undergoing this operation they underwent a selective angiographic embolization of the arterial inflow for control of hemorrhage by application of polyvinyl alcohol particles to the afferent arteries. This procedure led to a complete interruption in arterial inflow and the subsequent laparoscopic resection itself could be carried out as planned with minimal blood loss as well an uncomplicated postoperative course. The patients demonstrated a high degree of subjective satisfaction with the procedure. A reduction in arterial inflow through selective embolization is a useful tool in the preparation for laparoscopic resection of large, well-vascularized liver tumors.

Abstract
Background
Treatment of suspected hepatocellular adenoma (HA) remains controversial. The aim of this study was to evaluate the management of HA at a time when magnetic resonance imaging (MRI) and computed tomography (CT) are highly sensitive methods for diagnosing HA.
Methods
Between January 2000 and January 2005, data from 48 consecutive women with HA (median age 36 years) were prospectively collected. The protocol for diagnostic work-up consisted of multiphasic MRI or CT. Management was observation if the tumour was smaller than 5 cm and surgical intervention if it was 5 cm or larger.
Results
The median follow-up was 24 (range 3–73) months. Sixteen (33 per cent) patients had invasive procedures because of tumour size 5 cm or larger, malignant characteristics or haemorrhage. The remaining 32 patients (67 per cent) were observed; haemorrhage and malignant degeneration did not occur and none of the lesions showed enlargement after withdrawal of oral contraceptives. Multiple HAs were found in 32 (67 per cent) patients; liver steatosis was significantly more common in these patients than in those with a solitary lesion (59 versus 19 per cent; P = 0·008).
Conclusion
Observation of adenomas smaller than 5 cm is justified because of improved radiological reliability. Resection should be reserved for patients with malignant tumour characteristics or with single lesions 5 cm or larger.

Abstract
Biliary cystadenomas are rare, cystic neoplasms of the biliary ductal system that usually occur in middle-aged women. They cannot be safely differentiated from cystadenocarcinomas before operation and should always be considered for resection. Cystadenomas have a strong tendency to recur, particularly following incomplete excision, and a potential of malignant transformation. Therefore, complete resection is the therapy of choice and thorough histopathologic evaluation is imperative. A case of benign biliary cystadenoma with mesenchymal stroma is presented along with a review of the relative literature addressing the clinical presentation, histology, histogenesis, differential diagnosis, imaging features, treatment and prognosis of this interesting and rare entity.

Abstract
The major impediment to a wider application of living donor hepatectomy, particularly of the right lobe, is its associated morbidity. The recent interest in a minimally invasive approach to liver surgery has raised the possibility of applying these techniques to living donor right lobectomy. Herein, we report the first case of a laparoscopic, hand-assisted living donor right hepatic lobectomy. We describe the technical aspects of the procedure, and discuss the rationale for considering this option. We propose that the procedure, as described, did not increase the operative risks of the procedure; instead, it decreased potential morbidity. We caution that this procedure should only be considered for select donors, and that only surgical teams familiar with both living donor hepatectomy and laparoscopic liver surgery should entertain this possibility.

Abstract
BACKGROUND Hepatocellular adenomas (HCA) may present with spontaneous haemorrhage and rupture. The aim of this study was to assess management in 22 patients treated for haemorrhage and/or rupture of HCA. PATIENTS AND METHODS Between May 1990 and July 2005, 22 female patients were diagnosed with acute haemorrhage and/or rupture of lesions highly suspicious of HCA. Preoperative imaging diagnostics and pathologic specimens were reviewed. RESULTS Twelve haemodynamically stable and four unstable patients could be treated conservatively. One patient underwent acute partial liver resection, whereas four patients underwent laparotomy with initial packing of the liver. In one patient, selective embolisation of the left hepatic artery was performed. Fifteen patients eventually underwent resection after a mean time of 8 months after initial treatment. Six patients did not undergo resection and showed no complications or rebleeding after a mean follow-up of 24.6 months. Only in seven patients, histopathological examination showed HCA, and in one patient, HCA with focal nodular hyperplasia. CONCLUSION HCA with haemorrhage and/or rupture does not necessarily require immediate liver resection. Conservative treatment is justified in stable patients. In case of an instable patient with or without hemoperitoneum, laparotomy with packing or selective embolisation can stop the bleeding.

Abstract
Laparoscopy is the process of inspecting the abdominal cavity through an endoscope. Carbon dioxide is most universally used to insufflate the abdominal cavity to facilitate the view. However, several pathophysiological changes occur after carbon dioxide pneumoperitoneum and extremes of patient positioning. A thorough understanding of these pathophysiological changes is fundamental for optimal anesthetic care. Because expertise and equipment have improved, laparoscopy has become one of the most common surgical procedures performed on an outpatient basis and to sicker patients, rendering anesthesia for laparoscopy technically difficult and challenging. Careful choice of the anesthetic technique must be tailored to the type of surgery. General anesthesia using balanced anesthesia technique including several intravenous and inhalational agents with the use of muscle relaxants showed a rapid recovery and cardiovascular stability. Peripheral nerve blocks and neuraxial anesthesia were both considered as safe alternative to general anesthesia for outpatient pelvic laparoscopy without associated respiratory depression. Local anesthesia infiltration has shown to be effective and safe in microlaparoscopy for limited and precise gynecologic procedures. However, intravenous sedation is sometimes required. This article considers the pathophysiological changes during laparoscopy using carbon dioxide for intra-abdominal insufflation, outlines various anesthetic techniques of general and regional anesthesia, and discusses recovery and postoperative complications after laparoscopic abdominal surgery.

We present a case report of hepatic resection performed laparoscopically for a giant symptomatic hemangioma. The patient was a 50-year-old woman who was diagnosed with a giant hemangioma 20 cm in diameter. As in the case of our patient, laparoscopic resection of hepatic hemangiomas can be performed successfully, even when dealing with giant hemangiomas. However, a thorough preoperative assessment and a structured approach, in our case including preoperative embolization, is crucial for success.

Abstract
The caudate lobe of the liver, segment 1 (S1), is located between the hepatic hilum and the inferior vena cava. Resection of S1 alone, without sacrificing other parts of the liver, is a surgical challenge. We present 2 cases of isolated laparoscopic resections of hepatic S1. We are the first to describe this laparoscopic technique. Two patients affected by colorectal liver metastases confined to S1 underwent laparoscopic isolated resections of S1 using a left approach. One of them also underwent left lateral segmentectomy. Both interventions were accomplished laparoscopically without conversion. Operative time for the first patient was 150 minutes and that for the second patient was 105 minutes. Blood loss was 200 and 100 mL for the first and second patients, respectively. There were no major intraoperative complications except for a tear in the inferior vena cava in the first patient that was repaired without the need for conversion. The postoperative course was uneventful for both patients. The duration of hospital stay was 10 and 8 days, respectively. The resected margins of the specimens were tumor-free (R0 resections). The 2 patients are alive and disease-free 7 and 5 months after the procedure. Isolated laparoscopic resection of the hepatic caudate lobe can be performed by a highly skilled surgeon, but should be performed only in selected cases.

Abstract
Despite the advances in minimally invasive surgery in children, considerable concern exists about employing such techniques in oncologic cases. We report our experience with a 4-year-old girl with a symptomatic tumor in the liver. Contrast-enhanced computed tomography revealed a 3 x 4 cm lesion, confined to segments II and III. Tumor markers were negative and true-cut needle biopsy did not rule out malignancy. We performed a diagnostic laparoscopy using four 5-mm ports. Since the tumor did not cause any alterations of the liver surface, a 5-mm flexible endoscopic ultrasound probe (5 MHz) was applied to reveal the extent of the tumor. Parenchymal dissection was performed with a radiofrequency probe, and the LigaSure device was used to seal larger vessels and bile ducts. The tumor was resected completely and removed in a specimen bag via the umbilical incision. Histology revealed fibrous nodular hyperplasia. The postoperative course was uneventful and the girl was discharged on postoperative day 5. We conclude that laparoscopic resection of confined liver lesions is feasible in children, employing standard principles of oncologic surgery and safety.

Abstract
INTRODUCTION Laparoscopic liver resection (LLR) of solid liver tumors (SLT) has not become widespread due to technical problems, the risk of air embolism, and possible tumoral spread in malignant lesions. We present our experience of LLR in SLT. PATIENTS AND METHOD Between January 2003 and May 2005, we performed the laparoscopic approach in 16 patients with SLT. Preoperative diagnosis was liver metastases from colorectal carcinoma in 11 patients and benign tumor in the remaining five patients. Five of the lesions were located in the left lobe, another 10 in the right lobe (two in S. V, four in S. VI and four in S. VII) and the remaining lesion was bilobar (S. III and VI). LLRs were performed by complete laparoscopic hepatectomy (CLH) (n=8) and assisted laparoscopic hepatectomy (ALH) (n=8). LLR was completed in 13 patients (81%). Surgical technique (n=13) consisted of three left lobectomies, one with partial resection of S. IV, three bisegmentectomies (two of S. VI and VII and one of S. III and IV, the latter associated with metastasectomy in S. VIII), five segmentectomies (one of S. II, two of S. V and two of S. VI, one of the latter associated with metastasectomy in S. VII) and two local resections of benign tumors. RESULTS There was no intra- or postoperative mortality. With CLH the LLR was completed in five patients (62%), whereas with ALH there were no conversions. Only one of the 13 resected patients required transfusion. Seventeen nodules were excised in the 13 LLR, and 12 of 17 required the Pringle maneuver. The mean length of hospital stay was 4.9 days (3-14 days). Only one female patient (7.7%) developed an infected hematoma, requiring radiological drainage. CONCLUSION LLR of benign SLTs shows all the advantages of laparoscopy. In the case of malignant lesions, greater experience is needed to confirm the safety and effectiveness of the open approach.

Abstract
BACKGROUND/PURPOSE Laparoscopy for liver resection is highly specialized field because laparoscopic liver surgery presents severe technical difficulties, such as control of bleeding and risk of gas embolism. At present, a limited number of laparoscopic anatomical left lobectomies have been reported in the literature, but we believe that the use of stapling devices has made this technique safer and faster. METHODS From January 2000 to May 2005, eight patients (five men, three women; mean age, 60.5 years) underwent laparoscopic anatomical left lobectomy at our department. Seven patients presented with hepatocellular carcinoma and cirrhosis, while one patient had a large symptomatic angioma. The average size of the lesions was 4.18 cm (range, 3.6-7.1 cm); all the lesions were localized in the anatomical left lobe (segments II-III). Transection of the liver parenchyma, together with sectioning of the vascular pedicle for segment II and III and of the left hepatic vein, was obtained by the use of stapling devices. RESULTS The mean operative time was 142 min (range, 120-180 min). There were no intraoperative or postoperative complications, and blood transfusions were not required. The mean postoperative hospital stay was 5.75 days. CONCLUSIONS The key points of the technique are: late mobilization of the liver; no transection of the round ligament; no surrounding or taping of the portal pedicles or of the left hepatic vein; and the use of three consecutive linear staplers, turned to the left for transecting the liver parenchyma and vascular pedicle together. This technique, in our opinion, should be considered a new good option for patients with isolated lesions of the left lateral segments, but it must be performed by surgeons trained in both liver and advanced laparoscopic surgery.

Abstract
BACKGROUND Although laparoscopy in general surgery is increasingly being performed, only recently has liver surgery been performed with laparoscopy. We critically review our experience with laparoscopic liver resections. METHODS From January 2000 to April 2004, we performed laparoscopic hepatic resection in 16 patients with 18 hepatic lesions. Nine lesions were benign in seven patients (five hydatid cysts, three hemangiomas, and one simple cyst), five were malignant in five patients (five hepatocarcinoma), and four patients had an uncertain preoperative diagnosis (one suspected hemangioma and three suspected adenomas). The mean lesion size was 5.2 cm (range, 1-12). Twelve lesions were located in the left lobe, three were in segment VI, one was in segment V, one was in segment IV, and one was in the subcapsular part of segment VIII. RESULTS The conversion rate was 6.2%; intraoperative bleeding requiring blood transfusions occurred in two patients. Mean operative time was 120 min. Mean hospital stay was 4 days (range, 2-7). There were no major postoperative complications and no mortality. CONCLUSIONS Hepatic resection with laparoscopy is feasible in malignant and benign hepatic lesions located in the left lobe and anterior inferior right lobe segments (IV, V, and VI). Results are similar to those of the open surgical technique in carefully selected cases, although studies with large numbers of patients are necessary to drawn definite conclusions.
