A Prediction Model Intended for Exploratory Laparoscopy Risk Stratification in Colorectal Cancer Patients With Potential Occult Peritoneal Metastasis. Front Oncol 2022; 12:943951. [PMID: 35912189 PMCID: PMC9326510 DOI: 10.3389/fonc.2022.943951] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Accepted: 06/22/2022] [Indexed: 11/20/2022] Open
Abstract
Background The early diagnosis of occult peritoneal metastasis (PM) remains a challenge due to the low sensitivity on computed tomography (CT) images. Exploratory laparoscopy is the gold standard to confirm PM but should only be proposed in selected patients due to its invasiveness, high cost, and port-site metastasis risk. In this study, we aimed to develop an individualized prediction model to identify occult PM status and determine optimal candidates for exploratory laparoscopy. Method A total of 622 colorectal cancer (CRC) patients from 2 centers were divided into training and external validation cohorts. All patients’ PM status was first detected as negative on CT imaging but later confirmed by exploratory laparoscopy. Multivariate analysis was used to identify independent predictors, which were used to build a prediction model for identifying occult PM in CRC. The concordance index (C-index), calibration plot and decision curve analysis were used to evaluate its predictive accuracy and clinical utility. Results The C-indices of the model in the development and validation groups were 0.850 (95% CI 0.815-0.885) and 0.794 (95% CI, 0.690-0.899), respectively. The calibration curve showed consistency between the observed and predicted probabilities. The decision curve analysis indicated that the prediction model has a great clinical value between thresholds of 0.10 and 0.72. At a risk threshold of 30%, a total of 40% of exploratory laparoscopies could have been prevented, while still identifying 76.7% of clinically occult PM cases. A dynamic online platform was also developed to facilitate the usage of the proposed model. Conclusions Our individualized risk model could reduce the number of unnecessary exploratory laparoscopies while maintaining a high rate of diagnosis of clinically occult PM. These results warrant further validation in prospective studies. Clinical Trial Registration https://www.isrctn.com, identifier ISRCTN76852032

Abstract
BACKGROUND Laparoscopic liver resections (LLR) have been increasingly performed in recent years. Most of the available evidence, however, comes from specialized centers in Asia, Europe and USA. Data from South America are limited and based on single-center experiences. To date, no multicenter studies evaluated the results of LLR in South America. The aim of this study was to evaluate the experience and results with LLR in South American centers. METHODS From February to November 2019, a survey about LLR was conducted in 61 hepatobiliary centers in South America, composed by 20 questions concerning demographic characteristics, surgical data, and perioperative results. RESULTS Fifty-one (83.6%) centers from seven different countries answered the survey. A total of 2887 LLR were performed, as follows: Argentina (928), Brazil (1326), Chile (322), Colombia (210), Paraguay (9), Peru (75), and Uruguay (8). The first program began in 1997; however, the majority (60.7%) started after 2010. The percentage of LLR over open resections was 28.4% (4.4-84%). Of the total, 76.5% were minor hepatectomies and 23.5% major, including 266 right hepatectomies and 343 left hepatectomies. The conversion rate was 9.7%, overall morbidity 13%, and mortality 0.7%. CONCLUSIONS This is the largest study assessing the dissemination and results of LLR in South America. It showed an increasing number of centers performing LLR with the promising perioperative results, aligned with other worldwide excellence centers.

Abstract
Background Laparoscopic hepatectomy (LH) has been identified to be effective and safe for elderly patients (≥70 years). This study aims to assess the short-and long-term outcome of totally laparoscopic liver resection for elderly patients with Hepatocellular carcinoma (HCC). Methods We retrospectively reviewed 93 patients with HCC who underwent LH from August, 2003 to July, 2013 in a single center. Short-term operative and postoperative outcomes together with long-term outcomes, including disease free survival (DFS) and overall survival (OS) were analyzed. Results A total of 81 patients was finally reviewed, of which 23 patients (28.40%) were grouped to elderly (≥70 years) and 58 patients (71.60%) were divided into younger group (< 70 years). The mean ages of patients in the elderly and younger cohorts were 74.9 ± 3.4 and 50.9 ± 12.7 years old, respectively. The median follow-up durations in elderly cohort and young cohort were 30 months and 24 months. The mean postoperative hospital stay was nearly 4 days longer in the elderly cohort than that in younger group (13.4 vs 9.5; p = 0.003). The elderly cohort has a higher rate of non-surgical complications than that in the younger cohort (P = 0.045), while the risks of surgical complications were comparable between the two groups. For the postoperative complications, elderly patients were more easily to develop grade III or more of Clavien-Dindo classification than that in the younger patients (P = 0.008). The median OS in the elderly group and younger group was 44.09 months and 42.49 months, respectively, with p = 0.089. The median DFS in the elderly group and the younger group was 39.87 months and 37.86 months, respectively, with p = 0.0616. Conclusions Elderly patients could obtain comparable operative and survival benefits from LH for HCC as younger counterparts. Age may not be a contraindication to laparoscopic liver resection for elderly patients.

Abstract
Laparoscopic hepatectomy carries a high risk of gas embolism due to the extensive hepatic transection plane and large hepatic vena cava. Here, we compared the influence of inhaled and intravenous anesthetics on gas embolism during laparoscopic hepatectomy. Fifty patients undergoing laparoscopic hepatectomy were divided into two groups to receive sevoflurane anesthesia (group S, n = 25) or intravenous propofol anesthesia (group p, n = 25). During the operation, gas emboli were detected by transesophageal echocardiography and graded according to their size. Venous CO2 emboli were detected in all patients, and the embolism grades did not differ between the two groups. However, the mean embolism episode duration was longer in group S than group P (51.24±23.59 vs. 34.00±17.13 sec, p < 0.05). At the point of the most severe gas embolism, the PTCO2 was higher in group S than group p (44.00±4.47 vs. 41.36±2.77 mmHg, p < 0.05), while the PO2/FiO2 (450.52±54.08 vs. 503.80±63.18, p < 0.05) and pH values (7.35±0.05 vs. 7.38±0.02, p < 0.05) were lower in group S than group P. Patients with a history of abdominal surgery or liver cirrhosis had higher gas embolism grades. Thus volatile anesthetics may lengthen the duration of embolism episodes and worsen hemodynamics and pulmonary blood gas exchange during surgery.

Abstract
Background Surgeons may expect technical difficulties and worse outcomes when performing laparoscopic hepatectomy (LH) on obese patients. The aim of this study is to assess the impact of body mass index (BMI) on short-term surgical outcomes and to verify risk factors of conversion rate and complications of LH. Methods Data were collected from 551 patients who underwent attempted LH between August 1998 and April 2013. Patients were classified into four groups depending on their BMI according to the WHO’s definition of obesity for Asia-Pacific region: underweight <18.5 kg/m2 (Group1); normal 18.5–23.9 kg/m2 (Group2); overweight 24–27.9 kg/m2 (Group3); obese ≥ 28 kg/m2 (Group4) respectively. Short-term surgical outcomes were compared across the BMI categories. Possible risk factors concerned conversion rate and complications were analyzed. Results The overall conversion rate of the 551 patients was 13.07 %. Conversion rate for Group 1, 2, 3, and 4 were 14.3 % (n = 5), 11.2 % (n = 38), 13.0 % (n = 19), and 34.5 % (n = 10) respectively. Patients within the obese group had a much higher conversion rate. The overall complications rate was 11.98 %, where the complication for Group 1, 2, 3, and 4 were 22.9 % (n = 8), 12.7 % (n = 43), 18.2 % (n = 12), and 10.3 % (n = 3) respectively. Patients within the underweight group had a higher complication rate, but it did not reach statistic difference. Obesity and surgical site of left lobe were independent risk factors of conversion. Age, abdominal surgery history, and type of left and right lobe resection were independent risk factors for complications. Conclusions In China, obesity increases risk of conversion rate but it dose not affect surgical complications and other short-outcomes after LH.

Abstract
INTRODUCTION Hepatolithiasis is a prevalent disease in the southeastern coastal regions of China. Partial hepatectomy is the most definitive treatment for hepatolithiasis. This study evaluated the safety and efficacy of the laparoscopic left hemihepatectomy (LLH) for left-sided hepatolithiasis. METHODS The clinical data of 37 consecutive patients who underwent pure LLH for left-sided hepatolithiasis at Yinzhou Second Hospital between March 2009 and December 2013 were reviewed retrospectively. RESULTS Pure LLH was performed successfully in 36 patients. Because of severe adhesions from previous choledochotomy, 1 patient was converted to open procedure. The mean operative time was 257.9 minutes (range, 188 to 396 min). The mean duration of postoperative hospital stay was 11.7 days (range, 8 to 21 d). There were 2 (5.4 %) cases of postoperative bile leakage, 2 (5.4%) cases of intra-abdominal fluid collection, and 1 (2.7%) case of incisional infection, which were successfully managed conservatively. Residual stones were observed in 2 (5.4%) patients. The residual stones were located in the common bile duct in these cases and were removed through the T-tube tract by choledochoscopy. During a mean follow-up of 31.3 months (range, 6 to 63 mo), recurrent stones were detected in 2 (5.4%) patients and were successfully treated with endoscopic sphincterotomy. CONCLUSIONS LLH for left-sided hepatolithiasis is feasible and safe in selected patients.

Abstract
BACKGROUND Laparoscopic right hepatectomy (LRH) is increasingly performed for the treatment of many liver diseases. However, it remains a challenging procedure and is limited to highly specialized centers. Increasing the safety and efficacy of LRH is crucial. This study evaluated the safety and feasibility of the novel caudal approach (CDA) in LRH and in comparison with the conventional approach (CA). METHODS Of a total of 40 patients who underwent LRH between June 2007 and July 2015 at our center, 10 cases underwent the CDA, while 30 underwent the CA. Operative and postoperative outcomes were analyzed. RESULTS Clinical data and patient characteristics were comparable between the two groups. Only 1 patient required a laparoscopic-assisted procedure in the CDA group, while 14 patients were converted to laparotomy (n = 10) or laparoscopic-assisted procedures (n = 4) in the CA group, although the difference did not reach statistical significance (P = .060). However, the difference in conversion to laparotomy between the two groups was significant (P = .043). In addition, when considering 23 patients with malignancies, the median surgical margin was significantly greater in the CDA group (n = 6) (20 mm versus 10 mm; P = .023) than in the CA group (n = 17). Other operative and postoperative outcomes were similar between the two groups. CONCLUSIONS The CDA achieves safety and feasibility similar to that of the CA in LRH and requires relatively less conversion to laparotomy. In selected patients, the CDA offers an alternative option to the CA for LRH in experienced hands. Further studies with larger samples are warranted to evaluate the CDA.

Abstract
Laparoscopic liver resection (LLR) has been progressively developed along the past two decades. Despite initial skepticism, improved operative results made laparoscopic approach incorporated to surgical practice and operations increased in frequency and complexity. Evidence supporting LLR comes from case-series, comparative studies and meta-analysis. Despite lack of level 1 evidence, the body of literature is stronger and existing data confirms the safety, feasibility and benefits of laparoscopic approach when compared to open resection. Indications for LLR do not differ from those for open surgery. They include benign and malignant (both primary and metastatic) tumors and living donor liver harvesting. Currently, resection of lesions located on anterolateral segments and left lateral sectionectomy are performed systematically by laparoscopy in hepatobiliary specialized centers. Resection of lesions located on posterosuperior segments (1, 4a, 7, 8) and major liver resections were shown to be feasible but remain technically demanding procedures, which should be reserved to experienced surgeons. Hand-assisted and laparoscopy-assisted procedures appeared to increase the indications of minimally invasive liver surgery and are useful strategies applied to difficult and major resections. LLR proved to be safe for malignant lesions and offers some short-term advantages over open resection. Oncological results including resection margin status and long-term survival were not inferior to open resection. At present, surgical community expects high quality studies to base the already perceived better outcomes achieved by laparoscopy in major centers’ practice. Continuous surgical training, as well as new technologies should augment the application of laparoscopic liver surgery. Future applicability of new technologies such as robot assistance and image-guided surgery is still under investigation.

Abstract
BACKGROUND Laparoscopic hepatectomy (LH) is highly difficult in the background of liver cirrhosis. In this case series, we aimed to summarize our prior experience of LH in liver cirrhosis grading Child-Pugh class B. METHODS In the LH database of Sir Run Run Shaw Hospital in Zhejiang, China, patients who were pathologically diagnosed with cirrhosis and graded as Child-Pugh class B or C were reviewed. RESULTS Five patients grading Child B were included. There was no Child C case in our LH database. For included cases, median blood loss (BL) was 800 (range, 240-1,000) mL, median operative time was 135 (range, 80-170) minutes, and median length of hospital stay was 9 (range, 7-15) days. Forty percent (2/5) of patients was converted to open. The postoperative complication (PC) rate was 20.0% (1/5). When these Child B cases were compared with Child A cases undergoing LH, there was no statistical significance in BL, complication rate, operative time, open rate and hospital stay (HS) (P>0.05). This finding was confirmed by two ways of matched comparisons (a 1:2 comparison based on age and gender, and a 1:1 propensity score matching). CONCLUSIONS Although relevant literatures had suggested feasibility of LH in cirrhotic cases grading Child A, this study was the first one to discuss the value of LH in Child B cases. Our prior experience showed that in selected patients, LH in Child B patients had the potential to be as safe as in Child A cases. The efficacy of LH in Child C patients needs further exploration.

Jin RA, Wang Y, Yu H, Liang X, Cai XJ. Total laparoscopic left hepatectomy for primary hepatolithiasis: Eight-year experience in a single center. Surgery 2015; 159:834-41. [PMID: 26518391 DOI: 10.1016/j.surg.2015.09.022] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2015] [Revised: 08/16/2015] [Accepted: 09/02/2015] [Indexed: 12/15/2022]
Abstract
BACKGROUND Primary hepatolithiasis is prevalent in some Asian countries. Hepatectomy is a definitive treatment for this disease. Whether laparoscopic left hepatectomy (LLH) is suitable for primary hepatolithiasis remains controversial, because LLH is more challenging technically. The aim of this study was to evaluate the outcomes of LLH for primary hepatolithiasis in a single center. METHODS This retrospective study included 96 consecutive patients who underwent LLH for primary hepatolithiasis in the Sir Run Run Shaw Hospital from May 2005 to December 2012. In addition, 105 patients who met the same inclusion criteria for LLH but underwent open left hepatectomy (OLH) for hepatolithiasis during the same period were reviewed for comparison. The patient characteristics, operative features, postoperative course, residual stone rate, and recurrent stone rate were analyzed. RESULTS In the LLH group, 81 patients (84.4%) underwent total LLH and 15 (15.6%) were converted to open hepatectomy. The volume of intraoperative blood loss was less in the LLH than OLH group (383 ± 281 vs 554 ± 517 mL; P = .005). The intraoperative transfusion rate was also significantly lower in the LLH group (8.3% vs 30.5%; P < .001). There were no differences between the LLH and OLH groups in operation time, duration of postoperative hospitalization, postoperative complication rate, residual stone rate, or recurrent stone rate. CONCLUSION In experienced hands, total LLH is a safe, effective, and promising treatment for patients with hepatolithiasis.

Abstract
BACKGROUND In 1998, the technique of laparoscopic hepatectomy by curettage and aspiration was developed and a special instrument, laparoscopic multifunctional operative dissector (LPMOD), was designed for this procedure. In the past 17 years, this procedure was developed gradually and had become the routine procedure for laparoscopic hepatectomy in local area. This paper is to report results of 17-year practice of this procedure. METHODS Patients who underwent laparoscopic hepatectomy from August 1998 to March 2015 were reviewed. Hepatectomies were performed using the technique of laparoscopic hepatectomy by curettage and aspiration. By using the LPMOD, liver parenchyma was crashed and aspirated immediately and the intrahepatic ducts and small vessels were preserved and were safely dissected for ligation. Laparoscopic selective hepatic flow occlusion was performed routinely for hemi-hepatectomies to control intraoperative blood loss. RESULTS A total of 855 cases underwent laparoscopic hepatectomy by curettage and aspiration. No perioperative death, 105 patients were converted to open operation, and 84 of them were converted before liver transection without any emergency. Postoperative bleeding occurred in three patients (0.4 %), and bile leakage occurred in seven patients (0.8 %). CONCLUSION Laparoscopic hepatectomy by curettage and aspiration is a safe procedure for liver resection with acceptable morbidity and mortality.

Abstract
The "ALPPS" (associating liver partition with portal vein ligation for staged hepatectomy) procedure enables the rapid growth of the future liver remnant and extended surgical indication to patients with an "insufficient" future liver remnant. In May 2014, a 64-year-old male patient was admitted. The computed tomography (CT) scan showed multiple right liver lesions, which were diagnosed to be hepatocellular carcinoma by liver biopsy. The future liver remnant volume after right hemihepatectomy was calculated to be 35.6% based on the CT reconstruction. Completely laparoscopic ALPPS using round-the-liver ligation, which replaced liver splitting, was performed on him. The two-stage operation was performed successfully. The future liver remnant volume increased 37.9% according to the CT scan on Day 10 after the first-stage operation. The second-stage operation was performed on Day 14 after the first-stage operation. The patient recovered uneventfully. No bile leakage occurred. Thus the round-the-liver ligation can be safely executed in laparoscopy. Completely laparoscopic ALPPS using round-the-liver ligation is feasible and could result in a rapid hypertrophy of the liver remnant in patients with liver cancer complicated with cirrhosis.

Laparoscopic versus open left hemihepatectomy for hepatolithiasis. J Surg Res 2015; 199:402-6.

Abstract
BACKGROUND Partial hepatectomy is the most definitive treatment for hepatolithiasis. Laparoscopic liver resection, however, presents unique technical challenges. The objectives of this study were to evaluate and compare the safety and perioperative and long-term outcomes of laparoscopic left hemihepatectomy (LLH) versus open left hemihepatectomy (OLH) for left intrahepatic duct stones. METHODS From March 2009-October 2014, 97 consecutive patients with left intrahepatic duct stones who underwent LLH (n = 46) or OLH (n = 51) were evaluated. We retrospectively reviewed the clinical outcomes and the stone clearance rates of the 97 patients in this study. RESULTS The median surgical procedure times were 254 min (188-396 min) in the LLH group and 236 min (192-395 min) in the OLH group. No significant difference was found in the surgical procedure times between the two groups. The intraoperative blood loss of the LLH group was less than the OLH group (332 mL [247-914 mL] versus 369 mL [221-996 mL], P = 0.13), but there was no statistical significance. A shorter length of postoperative hospital stay was noticed in laparoscopy group (11 d [8-21 d] versus 12 d [9-24 d], P = 0.01). Postoperative complications were observed in six of the 46 patients (13.0%) after LLH and in 11 of the 51 patients (21.6%) after OLH (P = 0.27). Laparoscopy was comparable with laparotomy in the effectiveness of stone clearance during the first attempt (93.5% versus 94.1%, P = 1.00). CONCLUSIONS In left-sided hepatolithiasis, LLH was safe and effective: it resulted in low postoperative morbidity, no mortality, and a high stone clearance rate. The potential benefit of LLH was a shorter hospital stay. If consideration is given to the appropriate indication criteria, including the extent of hepatectomy and the location and distribution of lesions, LLH may be an excellent choice for treatment of left-sided hepatolithiasis.

Three-step method for systematic lymphadenectomy in gastric cancer surgery using the 'curettage and aspiration dissection technique' with Peng's multifunctional operative dissector. World J Surg Oncol 2014; 12:322. [PMID: 25344327 PMCID: PMC4223739 DOI: 10.1186/1477-7819-12-322] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2013] [Accepted: 10/01/2014] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Gastric cancer is one of the most common malignancies and is a leading cause of cancer death worldwide. Surgery is the most effective and successful method of treatment for gastric cancer, and systematic lymph node (LN) dissection is unquestionably the most effective procedure for treating LN metastases of gastric cancer. Systematic lymphadenectomy is the most important part of curative resection, but lymphadenectomy is also the most difficult procedure in gastric cancer surgery. The aim of this study is to report our three-step method for lymphadenectomy in gastric cancer. METHODS In this study, the lymph node stations and groups were defined according to the 13th edition of the Japanese Classification for Gastric Carcinoma. The authors' novel, simplified method consists of three steps: (1) the Kocher maneuver and dissection of the greater omentum together with the anterior sheet of the mesocolon, (2) dissection of the lesser omentum, and (3) lymphadenectomy following the main vessels. We primarily used Peng's multifunctional operative dissector, which combines four different functions (cutting, separating, aspirating and coagulating). Our systematic lymphadenectomy included three steps, and the main procedure started from right to left and in the caudal to cranial direction. RESULTS A total of 830 consecutive patients underwent our three-step-method systematic lymphadenectomy in advanced gastric cancer surgery. The mean operation time was 146 minutes, and the mean blood loss was 248 ml. The median postoperative hospital stay was 10.9±4.8 days. The median number of examined LN was 31.6 (range 17 to 72) per patient, and the median number of metastatic LN was 5.6 (range 0 to 42) per patient. The overall incidence of postoperative complications was 10.6%, and the rate of hospital death was 0.9%. The overall three-year survival rate was 52.6%. CONCLUSIONS Our three-step method for lymphadenectomy is easy to perform and is a useful procedure for gastric cancer surgery.

Abstract
Despite inception over 15 years ago and over 3000 completed procedures, laparoscopic liver resection has remained mainly in the domain of selected centers and enthusiasts. Requirement of extensive open liver resection (OLR) experience, in-depth understanding of anatomy and considerable laparoscopic technical expertise may have delayed wide application. However healthy scepticism of its actual benefits and presence of a potential publication bias; concern about its safety and technical learning curve, are probably equally responsible. Given that a large proportion of our work, at least in transplantation is still OLR, we have attempted to provide an entirely unbiased, mature opinion of its pros and cons in the current invited review. We have divided this review into two sections as we believe they merit separate attention on technical and ethical grounds. The first part deals with laparoscopic liver resection (LLR) in patients who present with benign or malignant liver pathology, wherein we have discussed its overall outcomes; its feasibility based on type of pathology and type of resection and included a small section on application of LLR in special scenarios like cirrhosis. The second part deals with the laparoscopic living donor hepatectomy (LDH) experience to date, including its potential impact on transplantation in general. Donor safety, graft outcomes after LDH and criterion to select ideal donors for LLR are discussed. Within each section we have provided practical points to improve safety in LLR and attempted to reach reasonable recommendations on the utilization of LLR for units that wish to develop such a service.

Abstract
BACKGROUND Laparoscopic liver resection has not been widely used because of intraoperative bleeding. This problem should be solved with instruments and techniques that require a short learning curve. MATERIALS AND METHODS The aim of this work was to present the technique used in our center to perform laparoscopic liver resection using the 'curettage and aspiration' technique with laparoscopic Peng's multifunctional operational dissectors and regional occlusion of inflow and outflow. We retrospectively analyzed patients who underwent a laparoscopic liver resection from August 1998 to August 2012, and collected the conversion rate, operating time, blood loss, hospitalization, bile leakage rate, bleeding rate, and other complications on a yearly basis and in total. We used SPSS software to analyze whether there was a significant difference, and summarized the learning curve of laparoscopic liver resection with various procedures. RESULTS We performed 365 cases of laparoscopic liver resection, including left hemihepatectomy, left lateral lobectomy, segmental hepatectomy, non-anatomic liver resection, right hemihepatectomy, and caudate lobectomy. The diseases included liver cancer, hepatolithiasis, liver hemangioma, focal nodular hyperplasia, liver abscess, and metastatic hepatic carcinoma. In total, 63 cases (17.20 %) were converted to open surgery because of severe adhesions, bleeding, or anatomical limitation. Mean blood loss was 370.6 ± 404.0 ml; mean operating time was 150.8 ± 73.0 min; and mean postoperation hospitalization was 9.2 ± 5.3 days. There were four cases (1.32 %) with the complication of bile leakage and two cases of hemorrhage (0.66 %). No intraoperative or postoperative deaths occurred. After finishing 15-30, 43, 35, and 28 cases of laparoscopic left hemihepatectomy, left lateral hepatectomy, non-anatomic liver resection, and segmentectomy, respectively, the average operating time, blood loss, and hospitalization were almost the same as the overall mean results. CONCLUSION The technique used in our center is a safe, fast, and effective approach to laparoscopic liver resection. Our 14 years of experience demonstrates that this technique can prevent postoperative bleeding and bile leakage. A surgeon can master the skill of laparoscopic left hemihepatectomy, left lateral hepatectomy, non-anatomic liver resection, and segmentectomy after ∼15-30, 43, 35, and 28 case procedures, respectively.

Abstract
BACKGROUND Hepatolithiasis removal is associated with high rates of postoperative residual and recurrence, which in some cases may require multiple surgeries. The progress and development of laparoscopic techniques introduced a new way of treating hepatolithiasis. However, the selection criteria for laparoscopic hepatolithiasis surgery, particularly among patients with a history of biliary surgery, remain undetermined. This study aimed to evaluate the safety, feasibility, and efficacy of reoperation for the treatment of hepatolithiasis via a laparoscopic approach. METHODS A retrospective analysis of the perioperative course and outcomes was performed on 90 patients who underwent laparoscopic procedures for hepatolithiasis between January 1, 2008, and December 31, 2012. Thirty-eight patients had previous biliary tract operative procedures (PB group) and 52 patients had no previous biliary tract procedures (NPB). RESULTS There was no significant difference in operative time (342.3 ± 101.0 vs. 334.1 ± 102.7 min), intraoperative blood loss (561.2 ± 458.8 vs. 546.3 ± 570.5 ml), intraoperative transfusion (15.8 vs. 19.2 %), postoperative hospitalization (12.6 ± 4.2 vs. 13.4 % ± 6.3 days), postoperative complications (18.4 vs. 23.1 %), conversion to open laparotomy (10.5 vs. 9.6 %), or intraoperative stone clearance rate (94.7 vs. 90.4 %). There was also no significant difference in stone recurrence (7.9 vs. 11.5 %) and recurrent cholangitis (5.3 vs. 13.5 %) at a mean of 19 months of follow-up (range, 3-51 months) for PB patients compared to NPB patients. The final stone clearance rate was 100 % in both groups. CONCLUSIONS Reoperation for hepatolithiasis by laparoscopic approach is safe and feasible for selected patients who have undergone previous biliary operations.

Abstract
The current treatment of HCC is truly multidisciplinary. Notwithstanding, surgical management remains the gold standard which other therapies are compared to. Operative management is divided into transplantation and resection; the latter is further subdivided among open and laparoscopic approaches. Resection has become safer, remains superior to locoregional treatments, and can be a life-prolonging bridge to transplantation. The decision to pursue laparoscopic resection for HCC is driven by safety and a view toward the long-term management of both the malignancy and the underlying liver disease. For patients with a solitary HCC <5 cm in segments 2, 3, 4b, 5, and 6, no evidence of extrahepatic tumor burden, compensated liver disease, and the absence of significant portal hypertension, laparoscopy has an important role. Under these circumstances, resection can be performed with reduced mortality and morbidity and equivalent oncologic outcomes, disease-free survival, and overall survival when compared with similarly selected cirrhotic patients undergoing open resection. Blood loss and transfusion requirements are low, and laparoscopy itself does not expose the patient to complications and does not increase the risk of cancer recurrence or dissemination. Finally, because HCC recurrence remains high in the cirrhotic liver, treatment following surgical resection mandates routine surveillance and treatment by locoregional therapy, reresection, or transplantation as required-the latter two of which are facilitated by an initial laparoscopic resection.

Abstract
BACKGROUND We aimed to analyze the risk of an increased surgical indication rate in patients with benign tumors of the liver since the development of laparoscopy. Previous articles have reported increased numbers of laparoscopic procedures in different surgical fields. METHODS A literature search of MEDLINE (PubMed), Google Scholar, and The Cochrane Library was carried out. All articles that analyzed benign liver tumors (hemangiomas, focal nodular hyperplasia, and adenoma) were divided in two groups: group I included all manuscripts with open procedures between 1971 at 1990, and group II included all manuscripts with open or laparoscopic procedures between 1991 and 2010. Group II articles were divided into two subgroups. Subgroup IIA patients were treated by open or laparoscopic procedures between 1991 and 2000, and subgroup IIB patients were treated by open or laparoscopic procedures between 2001 and 2010. RESULTS Specific analysis of each kind of tumor observed in the two groups showed fewer surgically treated patients for hepatic hemangioma and hepatic adenoma in group II compared with group I and a greater number of patients for focal nodular hyperplasia. Fewer patients were treated with laparoscopic procedures in subgroup IIA than in subgroup IIB. A chi-square test with Yates' correction gave a P value of <0.001. CONCLUSION Laparoscopy has increased the rate of hepatic resection for benign tumors with doubtful indications.

Abstract
BACKGROUND Gastric cancer is one of the most common malignancies and a leading cause of cancer death. Complete resection is still the only treatment to offer a cure for patients with gastric cancer. Lymphadenectomy is the most important part of curative resection, but lymphadenectomy is also very difficult in gastric cancer surgery. The aim of this study was to report our 3-step method for lymphadenectomy and clarify its safety and value in gastric cancer. STUDY DESIGN A total of 120 consecutive patients underwent our 3-step method for lymphadenectomy at the Second Affiliated Hospital Zhejiang University College of Medicine between February 2006 and July 2007. The main surgical procedure was performed from right to left and from caudal to cranial. Clinical factors, surgical variables, postoperative morbidity, and hospital (30-day) mortality were analyzed retrospectively. RESULTS Total gastrectomy was performed in 41 patients; combined adjacent organ resection was performed in 9 patients. The mean operation time was 201.8 minutes, and the mean blood loss was 376.7 mL. The median postoperative hospital stay was 14.9 ± 4.3 days. A total of 3,569 lymph nodes (LNs) were removed and examined, and 2,879 were negative. More than 15 LNs were examined in all 120 patients. The median number of examined LNs was 29 (range 17 to 64; mean 29.7 ± SD 9.6) per patient, and the median number of positive LNs was 5 (range 0 to 37; mean 5.8 ± SD 7.1) per patient. The overall incidence of postoperative complications was 10.8%, and the rate of hospital death was 0%. The median follow-up period for those patients was 34.3 months (range 10 to 53 months), and the overall 3-year survival rate was 40.6%. CONCLUSIONS The 3-step method for lymphadenectomy is easy to perform and is a safe and useful procedure for gastric cancer surgery.

Abstract
An increasing number of studies are reporting the outcomes and benefits of laparoscopic liver resection. This article reviews the literature with emphasis on a recent consensus conference on laparoscopic liver resection in 2008, the learning curve for laparoscopic liver surgery, laparoscopic major hepatectomies, oncologic outcomes of laparoscopic liver resection for hepatocellular carcinoma and colorectal cancer liver metastases, and the comparative benefits of laparoscopic versus open liver resection. Current evidence suggests that minimally invasive hepatic resection is safe and feasible with short-term benefits, no economic disadvantage, and no compromise to oncologic principles.

Abstract
OBJECTIVE To evaluate the "learning curve" effect on feasibility and reproducibility of laparoscopic liver resection (LLR). SUMMARY BACKGROUND DATA LLR is currently limited to few centers and to few procedures. Its reproducibility is still debated. METHODS : Patients undergoing LLR between 1996 and 2008 were included. Indications and type of hepatectomies were compared with those of open resections performed in the same period, considering 3 periods (1996-1999, 2000-2003, and 2004-2008). LLRs were divided into 3 equal groups of 58 cases and technical data and outcomes were compared. Risk-adjusted Cumulative Sum model was used for determining the learning curve based on the need for conversion. RESULTS Of 782, 174 (22.3%) patients underwent LLR. Proportion of LLR progressively increased (17.5%, 22.4%, and 24.2%), such as hepatocellular carcinoma (17.6%, 25.6%, and 39.4%, P < 0.05), colorectal metastases (0%, 6.5%, and 13.1%, P < 0.05), major hepatectomies (1.1%, 9.1%, 8.5%, P < 0.05), and right hepatectomies (0%, 13.2%, and 13.1%, P < 0.05). Comparing groups, results of LLR significantly improved in terms of conversion rate (15.5%, 10.3%, and 3.4%, P < 0.05), operative time (210, 180, and 150 minutes, P < 0.05), blood loss (300, 200, and 200 mL, P < 0.05), and morbidity (17.2%, 22.4%, and 3.4%, P < 0.05). Pedicle clamping was less used over time (77.6%, 62.1%, and 17.2%, P < 0.05) and for shorter durations (45, 30, and 20 minutes, P < 0.05). Having adjusted for case-mix, the Cumulative Sum analysis demonstrated a learning curve for laparoscopic hepatectomies of 60 cases. CONCLUSION A slow but constant evolution of LLR occurred: indications and magnitude of procedures increased and technical outcomes improved. The learning curve demonstrated in this study suggests that LLR is reproducible in liver units but specific training to advanced laparoscopy is required.

Abstract
BACKGROUND Outcomes of laparoscopic liver resection (LLR) are not clarified. The objective of this article is to depict the state of the art of LLR by means of a systematic review of the literature. METHODS Studies about LLR published before September 2008 were identified and their results summarized. RESULTS Indications for laparoscopic hepatectomy do not differ from those for open surgery. Technical feasibility is the only limiting factor. Bleeding is the major intraoperative concern, but, if managed by an expert surgeon, do not worsen outcomes. Hand assistance can be useful in selected cases to avoid conversion. Patient selection must take both tumor location and size into consideration. Potentially good candidates are patients with peripheral lesions requiring limited hepatectomy or left lateral sectionectomy; their outcomes, including reduced blood loss, morbidity, and hospital stay, are better than those of their laparotomic counterparts. The same advantages have been observed in cirrhotics. Laparoscopic major hepatectomies and resections of postero-superior segments need further evaluation. The results of LLR in cancer patients seem to be similar to those obtained with the laparotomic approach, especially in cases of hepatocellular carcinoma, but further analysis is required. CONCLUSIONS Laparoscopic liver resection is safe and feasible. The laparoscopic approach can be recommended for peripheral lesions requiring limited hepatectomy or left lateral sectionectomy. Preliminary oncological results suggest non-inferiority of laparoscopic to laparotomic procedures.

Abstract
BACKGROUND Laparoscopic liver resection was performed at some institutes. The procedure mainly included local resection, segmentectomy, and left lateral segmentectomy. With experience accumulation and technique innovation, laparoscopic left hemihepatectomy was performed in selected patients. This study was designed to introduce and evaluate the safety and feasibility of this procedure. METHODS Nineteen successive patients underwent laparoscopic left hemihepatectomy from 2005 to 2007. They were compared by the matched-pair method with 19 other patients who underwent conventional open left hemihepatectomy. Surgical feature, postoperative course, and the learning curve of laparoscopic left hemihepatectomy were studied. RESULTS Laparoscopic hemihepatectomy was successfully performed in 17 cases. Two conversions were required. Compared with the open group, the blood loss was significantly less in the laparoscopic group (462 +/- 372 vs. 895 +/- 704, p = 0.03). Postoperative hospital stay of the laparoscopic group was shorter but not significant compared with the open group (9 +/- 5 vs. 13 +/- 7, p = 0.086). Postoperative albumin level in the laparoscopic group was significantly higher than the open group (33 +/- 4.8 vs. 27.6 +/- 3.2, p = 0.001). There was no perioperative mortality in either group. Two complications occurred in the laparoscopic group (11%) and four in the open group (21%). A tendency of gradually decreased transecting time was noticed in the early cases (R(2) = 0.676; p = 0.012). CONCLUSIONS Laparoscopic left hemihepatectomy is a safe and feasible procedure for select patients.

Abstract
BACKGROUND Previously, prior biliary tract surgery was considered a contraindication to laparoscopic biliary tract reoperation. In this paper, we present our experience with laparoscopic biliary tract reoperation for patients with the choledocholithiasis for whom the endoscopic sphincterotomy has failed or is contraindicated. PATIENTS AND METHODS A retrospective analysis was performed on data from the attempted laparoscopic reoperation of 39 patients, examining open conversion rates, operative times, complications, and length of hospital stay. RESULTS Of 39 cases, 38 were completed laparoscopically: 1 case required a conversion to the open operation because of difficulty in exposing the common bile duct. Mean operative time was 135 minutes. Mean postoperative hospital stay was 4 days. Procedures included 3 cases of laparoscopic residual gallbladder resection, 13 cases of laparoscopic common bile duct exploration and primary duct closure of choledochotomy, and 22 cases of laparoscopic common bile duct exploration and choledochotomy with T-tube drainage. There was 1 case of duodenal perforation during dissection, which was repaired laparoscopically. There were 2 cases of retained stones. Postoperative asymptomatic hypermalasia occurred in 3 cases. There were no complications due to port placement, no postoperative bleeding, bile or bowel leakage, and no mortality. At a mean follow-up time of 18 months, there was no recurrence or formation of duct stricture. CONCLUSIONS The laparoscopic biliary tract reoperation is safe and feasible for experienced laparoscopic surgeons and is an alternative choice for patients with choledocholithiasis for whom the endoscopic sphincterectomy has failed or is contraindicated.

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
AIM: To evaluate the safety and feasibility of biliary tract reoperation by laparoscopy for the patients with retained or recurrent stones who failed in endoscopic sphincterotomy.
METHODS: A retrospective analysis of data obtained from attempted laparoscopic reoperation for 39 patients in a single institution was performed, examining open conversion rates, operative times, complications, and hospital stay.
RESULTS: Out of the 39 cases, 38 (97%) completed laparoscopy, 1 required conversion to open operation because of difficulty in exposing the common bile duct. The mean operative time was 135 min. The mean post-operative hospital stay was 4 d. Procedures included laparoscopic residual gallbladder resection in 3 cases, laparoscopic common bile duct exploration and primary duct closure at choledochotomy in 13 cases, and laparoscopic common bile duct exploration and choledochotomy with T tube drainage in 22 cases. Duodenal perforation occurred in 1 case during dissection and was repaired laparoscopically. Retained stones were found in 2 cases. Postoperative asymptomatic hyperamylasemia occurred in 3 cases. There were no complications due to port placement, postoperative bleeding, bile or bowel leakage and mortality. No recurrence or formation of duct stricture was observed during a mean follow-up period of 18 mo.
CONCLUSION: Laparoscopic biliary tract reoperation is safe and feasible if it is performed by experienced laparoscopic surgeons, and is an alternative choice for patients with choledocholithiasis who fail in endoscopic sphincterectomy.

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
BACKGROUND The number of reported laparoscopic hepatectomies for liver malignancy is increasing, but comparative data on the survival outcomes between the patients who have undergone laparoscopic hepatectomy versus open surgery are still lacking. METHODS We compared 31 laparoscopic liver resections with 31 open liver resections in a pair-matched retrospective analysis with the aim of evaluating the intraoperative hazards, recovery, and survival outcomes of these procedures for liver cancer. The laparoscopic group and the open group were matched for age, sex, the size and location of the tumor, and the presence or absence of cirrhosis. RESULTS Thirty cases in the laparoscopic group were performed successfully while one case was converted to open surgery due to intraoperative hemorrhage. The length of hospital stay was 7.5 (5-15) days, which was significantly shorter than those in open group (p < 0.01). The mean operative time and blood loss in the laparoscopic group were 140.1 (60-380) min and 502.9 (50-2000) ml, respectively, which were lower than those in open group but without significant difference. There were no operative complications and no deaths in the laparoscopic group. The mean and median survival times of laparoscopic group were 59.3 and 70 months, compared with 49.4 and 60 months in the open group, respectively. The 1-, 3-, 5-year survival rates in the laparoscopic group were, respectively, 96.55%, 60.47%, and 50.40%, and 96.77%, 68.36%, and 50.64% in the open group. By log-rank test, these two survival curves were not significantly different (p = 0.8535). CONCLUSION This study shows that laparoscopic hepatectomy for liver malignancy in selected patients is a safe, effective, and oncologically efficient procedure with better short-term results and similar survival outcomes to open hepatectomy for liver malignancy after midterm follow-up.

Abstract
BACKGROUND AND AIMS To introduce a special dissection technique named "Curettage and Aspiration Dissection Technique" (CADT) using a versatile instrument called Peng's Multifunction Operative Dissector (PMOD) for liver resection. PMOD is an electrosurgical pencil with an inline suction, bearing four functions: electric cutting, coagulation, aspiration and dissection, The above-mentioned functions can be achieved simultaneously or sequentially during liver resection. The purpose of this study was to evaluate this technique and the special electrosurgical device in hepatic surgery. PATIENTS AND METHODS From June 2005 to December 2006, 70 consecutive patients with segmentectomy or major hepatectomy were performed with this dissection technique by the same surgeon. Peri-operative data and the technical aspect of this device and dissection technique for various types of liver resection were summarised. RESULTS Forty-nine of 70 cases with various degrees of cirrhosis. Median blood loss were 470 ml (100-2400 ml), the bleeding and mortality within one month postoperatively was zero. There were postoperative complications in 20 patients: bile leak occurred in five cases, nine cases with right pleural effusion and six with ascites. No relative complications with this method were found. CONCLUSION The CADT and PMOD can achieve better dissection and hemostasis. It possible is a much more valuable alternative to other devices currently used for liver surgery.

Abstract
BACKGROUND Hepatolithiasis is a prevalent disease in Southeast Asia. Hepatectomy was considered the best treatment for majority of cases. Laparoscopic hepatectomy is a new procedure for liver lesions that uses a minimal invasive approach. The aim of this study was to evaluate the feasibility and safety of laparoscopic hepatectomy for hepatolithiasis by comparing it with open hepatectomy. METHODS From November 2002 to March 2006 a total of 30 consecutive patients underwent laparoscopic hepatectomy for hepatolithiasis in Sir Run Run Shaw Hospital. Twenty-nine were included in this study (a converted case was excluded) and called the laparoscopic hepatectomy group (LH). During the same period 22 patients with hepatolithiasis who met the inclusion criteria for laparoscopic hepatectomy were selected for open hepatectomy and called the open group (OH). All operations were performed by the authors. There was no significant difference in preoperative data between the two groups. Data were statistically compared. RESULTS Compared with open hepatectomy, those who underwent laparoscopic hepatectomy had a shorter postoperative hospital stay and fasting time, a lower postoperative serum aminotransferase level, and a higher postoperative serum albumin level. Stone clearance rate (intermediate rate, 89.7% vs. 86.4%; final rate, 100% vs. 96.5%), stone recurrence rate (0% vs. 4.5%), operating time, and intraoperative blood loss were similar for the two groups. Six complications occurred, two (6.8%) in LH and four (18.2%) in OH. There was no perioperative mortality in either group. CONCLUSION Laparoscopic hepatectomy for hepatolithiasis is feasible and safe in selected 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.
