Surgical and Oncological Outcomes of Wedge Resection Versus Segment 4b + 5 Resection for T2 and T3 Gallbladder Cancer: a Meta-Analysis. J Gastrointest Surg 2023; 27:1954-1962. [PMID: 37221386 DOI: 10.1007/s11605-023-05698-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Accepted: 04/15/2023] [Indexed: 05/25/2023]
Abstract
BACKGROUND Liver resection is the standard operative procedure for patients with T2 and T3 gallbladder cancers (GBC). However, the optimal extent of hepatectomy remains unclear. METHODS We conducted a systematic literature search and meta-analysis to assess the safety and long-term outcomes of wedge resection (WR) vs. segment 4b + 5 resection (SR) in patients with T2 and T3 GBC. We reviewed surgical outcomes (i.e., postoperative complications and bile leak) and oncological outcomes (i.e., liver metastasis, disease-free survival (DFS), and overall survival (OS)). RESULTS The initial search yielded 1178 records. Seven studies reported assessments of the above-mentioned outcomes in 1795 patients. WR had significantly fewer postoperative complications than SR, with an odds ratio of 0.40 (95% confidence interval, 0.26 - 0.60; p < 0.001), although there were no significant differences in bile leak between WR and SR. There were no significant differences in oncological outcomes such as liver metastases, 5-year DFS, and OS. CONCLUSIONS For patients with both T2 and T3 GBC, WR was superior to SR in terms of surgical outcome and comparable to SR in terms of oncological outcomes. WR that achieves margin-negative resection may be a suitable procedure for patients with both T2 and T3 GBC.

Abstract
Gallbladder carcinoma (GC) is a rare type of cancer of the digestive system, with an incidence that varies by region. Surgery plays a primary role in the comprehensive treatment of GC and is the only known cure. Compared with traditional open surgery, laparoscopic surgery has the advantages of convenient operation and magnified field of view. Laparoscopic surgery has been successful in many fields, including gastrointestinal medicine and gynecology. The gallbladder was one of the first organs to be treated by laparoscopic surgery, and laparoscopic cholecystectomy has become the gold standard surgical treatment for benign gallbladder diseases. However, the safety and feasibility of laparoscopic surgery for patients with GC remain controversial. Over the past several decades, research has focused on laparoscopic surgery for GC. The disadvantages of laparoscopic surgery include a high incidence of gallbladder perforation, possible port site metastasis, and potential tumor seeding. The advantages of laparoscopic surgery include less intraoperative blood loss, shorter postoperative hospital stay, and fewer complications. Nevertheless, studies have provided contrasting conclusions over time. In general, recent research has tended to support laparoscopic surgery. However, the application of laparoscopic surgery in GC is still in the exploratory stage. Here, we provide an overview of previous studies, with the aim of introducing the application of laparoscopy in GC.

Abstract
Gallbladder carcinoma (GBC) is the most common biliary tract malignancy associated with a concealed onset, high invasiveness and poor prognosis. Radical surgery remains the only curative treatment for GBC, and the optimal extent of surgery depends on the tumor stage. Radical resection can be achieved by simple cholecystectomy for Tis and T1a GBC. However, whether simple cholecystectomy or extended cholecystectomy, including regional lymph node dissection and hepatectomy, is the standard surgical extent for T1b GBC remains controversial. Extended cholecystectomy should be performed for T2 and some T3 GBC without distant metastasis. Secondary radical surgery is essential for incidental gall-bladder cancer diagnosed after cholecystectomy. For locally advanced GBC, hepatopancreatoduodenectomy may achieve R0 resection and improve long-term survival outcomes, but the extremely high risk of the surgery limits its implementation. Laparoscopic surgery has been widely used in the treatment of gastrointestinal malignancies. GBC was once regarded as a contraindication of laparoscopic surgery. However, with improvements in surgical instruments and skills, studies have shown that laparoscopic surgery will not result in a poorer prognosis for selected patients with GBC compared with open surgery. Moreover, laparoscopic surgery is associated with enhanced recovery after surgery since it is minimally invasive.

Abstract
BACKGROUND Gallbladder carcinoma is a rare cancer with a poor prognosis and the most common biliary tract malignancy. This video shows robotic treatment of a patient with incidental gallbladder cancer diagnosed after laparoscopic cholecystectomy. The operation consisted of a robotic bisegmentectomy (liver segments 4b and 5) using a Glissonian approach and a hilar lymphadenectomy. METHODS A 73-year-old woman with no relevant history underwent a laparoscopic cholecystectomy at another hospital facility. The pathology revealed a gallbladder carcinoma. The patient was then referred for further treatment. Pathologic revision confirmed T2a carcinoma and staging was negative for distant metastases. The multidisciplinary team decided on a radical resection that will consist of a hilar lymphadenectomy and a frozen section of the cystic stump along the resection of segments 4b and 5. A robotic approach was proposed, and consent was obtained. RESULTS The operation time was 300 min and was performed 21 days after the cholecystectomy. Estimated blood loss was 120 mL with no transfusions required during or after the procedure. The postoperative recovery was uneventful, and the patient was discharged on the fourth postoperative day. The final pathology showed no residual disease in the liver specimen and no metastases among 16 removed lymph nodes. CONCLUSIONS The robotic approach is safe and feasible for radical treatment after incidentally discovered gallbladder cancer. The Glissonian approach is useful for anatomic resection of liver segments 4b and 5. This video can help oncologic surgeons to perform this challenging procedure.

World J Gastrointest Surg 2022; 14:1387-1396. [PMID: 36632125 PMCID: PMC9827575 DOI: 10.4240/wjgs.v14.i12.1387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Revised: 10/28/2022] [Accepted: 12/07/2022] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND With the development of laparoscopic techniques, gallbladder cancer (GBC) is no longer a contraindication to laparoscopic surgery (LS). Although LS is recommended for stage T1 GBC, the value of LS for stage T2 GBC is still controversial.
AIM To evaluate the short- and long-term outcomes of LS in comparison to those of open surgery (OS) for stage T2 GBC.
METHODS We searched the PubMed, Embase, Cochrane Library, Ovid, Google Scholar, and Web of Science databases for published studies comparing the efficacy of LS and OS in the treatment of stage T2 GBC, with a cutoff date of September 2022. The Stata 15 statistical software was used for analysis. Relative risk (RR) and weighted mean difference (WMD) were calculated to assess binary and continuous outcome indicators, respectively. Begg’s test and Egger’s test were used for detecting publication bias.
RESULTS A total of five studies were included, with a total of 297 patients, 153 in the LS group and 144 in the OS group. Meta-analysis results showed that the LS group was better than the OS group in terms of operative time [WMD = -41.29, 95% confidence interval (CI): -75.66 to -6.92, P = 0.02], estimated blood loss (WMD = -261.96, 95%CI: -472.60 to -51.31, P = 0.01), and hospital stay (WMD = -5.67, 95%CI: -8.53 to -2.81, P = 0.0001), whereas there was no significant difference between the two groups in terms of blood transfusion (RR = 0.60, 95%CI: 0.31-1.15, P = 0.13), complications (RR = 0.72, 95%CI: 0.39-1.33, P = 0.29), number of lymph nodes retrieved (WMD = –1.71, 95%CI: -4.27 to -0.84, P = 0.19), recurrence (RR = 0.41, 95%CI: 0.06-2.84, P = 0.36), 3-year and 5-year overall survival (RR = 0.99, 95%CI: 0.82-1.18, P = 0.89 and RR = 1.02, 95%CI: 0.68-1.53, P = 0.92; respectively), and 3-year and 5-year disease-free survival (RR = 1.01, 95%CI: 0.84-1.21, P = 0.93 and RR = 1.15, 95%CI: 0.90-1.46, P = 0.26; respectively).
CONCLUSION The long-term outcomes of LS for T2 GBC are similar to those of OS, but LS is superior to OS in terms of operative time, intraoperative bleeding, and postoperative hospital stay. Nevertheless, these findings should be validated via high-quality randomized controlled trials and longer follow-ups.

Abstract
BACKGROUND There is still controversy over whether to perform laparoscopic surgery for T3 stage gallbladder cancer. In addition, the necessity of segment 4b+5 liver resection for stage T3 gallbladder has not been reported. This article aims to explore the safety, effectiveness, and short-term prognosis of laparoscopic segment 4b+5 liver resection for T3 stage gallbladder cancer. METHODS This is a retrospective multicenter propensity score-matched study. Disease-free survival, perioperative complications, and intraoperative safety were analyzed to evaluate safety and effectiveness. RESULTS There was no significant difference in the incidence of intraoperative bleeding, number of lymph nodes obtained, postoperative complications, or disease-free survival (DFS) between the open group (OG) and laparoscopic group (LG) (P > 0.05). The DFS time of the S4b+5 resection group (S4b5) was longer than that of the wedge group (P = 0.016). Cox regression showed that positive margins (HR, 5.32; 95% CI 1.03-27.63; P = 0.047), lymph node metastasis (HR, 2.70; 95% CI 1.31-5.53; P = 0.007), and liver S4b+5 resection (HR, 0.30; 95% CI 0.14-0.66; P = 0.003) were independent risk factors for DFS. The operative time of indocyanine green (ICG) fluorescence-guided liver S4b5 segment resection was shorter than that of traditional laparoscopic S4b+5 resection guided by hepatic veins (P ≤ 0.001). CONCLUSION Laparoscopic liver S4b+5 resection for T3 stage gallbladder cancer is safe and feasible and can prolong DFS. ICG fluorescence-guided negative staining may reduce the difficulty of the operation.

Comparison of the Oncological Outcomes of Open versus Laparoscopic Surgery for T2 Gallbladder Cancer: A Propensity-Score-Matched Analysis. J Clin Med 2022; 11:jcm11092644. [PMID: 35566770 PMCID: PMC9099510 DOI: 10.3390/jcm11092644] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 04/25/2022] [Accepted: 05/06/2022] [Indexed: 02/01/2023] Open
Abstract
Although laparoscopic treatment for T1 gallbladder cancer (GBC) has been described previously, the differences in oncologic outcomes between laparoscopic and conventional open surgery for T2 GBC have not been investigated. We aimed to assess the role of laparoscopic surgery using retrospectively collected data for 81 patients with T2 GBC who underwent surgical resection between January 2010 and December 2017. Eligible patients were classified into “laparoscopic” and “open” groups. Propensity-score matching was performed in a 1:1 ratio. The effects of surgery type on surgical and oncological outcomes were investigated. After propensity-score matching, 19 patients were included in the open and laparoscopic surgery groups. The median follow-up durations were 70 and 26 months in the open and laparoscopic groups, respectively. The operative time (316.8 ± 80.3 vs. 218.9 ± 145.0 min, p = 0.016) and length of postoperative hospital stay (14.4 ± 6.0 vs. 8.4 ± 5.9 days, p = 0.004) were significantly shorter in the laparoscopic group. The three-year overall (86.3% vs. 88.9%, p = 0.660) and disease-free (76.4% vs. 60.2%, p = 0.448) survival rates were similar between the groups. Propensity-score matching showed that laparoscopic surgery for T2 GBC yielded similar long-term oncological outcomes and favorable short-term outcomes in comparison with open surgery. Laparoscopic treatment should be considered in patients with T2 GBC.

Abstract
Gallbladder cancer (GBC) is the most common biliary tract cancer worldwide and its incidence has significant geographic variation. A unique combination of predisposing factors includes genetic predisposition, geographic distribution, female gender, chronic inflammation, and congenital developmental abnormalities. Today, incidental GBC is the most common presentation of resectable gallbladder cancer, and surgery (minimally invasive or open) remains the only curative treatment available. Encouragingly, there is an important emerging role for systemic treatment for patients who have R1 resection or present with stage III-IV. In this article, we describe the pathogenesis, surgical and systemic treatment, and prognosis.

Abstract
Introduction: The outcome of laparoscopic extended cholecystectomy (EC) with wedge hepatic resection (LECW) in patients with gallbladder cancer (GBC) has been compared with that of open EC with wedge hepatic resection (OECW), but studies comparing laparoscopic EC with bi-segmentectomy (LECB) with open EC with bi-segmentectomy (OECB) are lacking. Patients and Methods: This retrospective study comprised of 68 patients with GBC who were offered either LECB or OECB from July 2011 to July 2018. Patients were divided into laparoscopic group (LG) and open group (OG), and appropriate statistical methods were used for comparison. Results: Out of the total 68 patients, 30 patients were in LG and 38 patients were in OG. Demographic, clinical and biochemical characteristics were similar except significantly higher number of male patients in OG (P = 0.01). In LG versus OG, the mean operation time was 286 versus 274 min (P = 0.565), mean blood loss was 158 versus 219 ml (P = 0.006) and mean hospital stay was 6.4 versus 9 days (P = 0.0001). The complication rate was 16.6% in LG and 31.5% in OG, but this difference was not statistically significant (P = 0.259). The median number of lymph nodes was 12 in both LG and OG (P = 0.62). Distribution of patients among American Joint Committee on Cancer stages I to IV was similar in both the groups (P = 0.5). Fifty percent of the patients in both the groups received adjuvant treatment (P = 1). In LG versus OG, the recurrence rate was 20% versus 28.9% (P = 0.4), mean recurrence-free survival was 48 months versus 44 months (P = 0.35) and overall survival was 51 months versus 46 months (P = 0.45). In LG versus OG, 1, 3 and 5-year survival was 96% versus 94%, 79% versus 72% and 79% versus 62% (P = 0.45). The median follow-up was statistically significantly shorter (24 vs. 36 months) in LG versus OG (P = 0.0001). Conclusions: The oncological outcome and survival after LECB in patients with resectable GBC is not inferior to that after OECB. Laparoscopic approach has a potential to improve perioperative outcome in patients with GBC.

[PMID: 33174099 DOI: 10.1007/s00464-020-08146-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Accepted: 10/27/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Surgical treatment is still the most effective treatment for gallbladder cancer. For the patients with stage T1b and above, the current guidelines recommend the extended radical operation, and oncologic extended resection can benefit the survival of the patients. The laparoscopic approach is still in the early phase, and its safety and oncological outcomes are not well known. OBJECTIVE To evaluate the technical feasibility and oncological outcomes of laparoscopic surgery for oncologic extended resection of early-stage incidental gallbladder carcinoma. RESULTS This study included 18 male and 32 female patients. Twenty patients underwent laparoscopic oncologic extended resection and 30 patients underwent open oncologic extended resection. All of the patients had R0 resection. A laparoscopic approach was associated with less intraoperative blood loss (242 ± 108.5 vs 401 ± 130.3; p < 0.01) and shorter duration of postoperative hospital stay (6.2 ± 2.4 vs 8.6 ± 2.3; p < 0.01). There was no statistically significant difference between two groups for lymph nodes yield (5.4 ± 3.5 vs 5.8 ± 2.1; p > 0.05), incidence of lymphatic metastasis (15% vs 16.67%; p > 0.05), residual disease (20% vs 23.3%; p > 0.05), and postoperative morbidity (15% vs 20%; p > 0.05). During follow-up time of median 20.95 (12-29.5) months, no significant difference was found between the two groups for early tumor recurrence (10% vs 13.33%; p > 0.05) and disease-free survival (p > 0.05). CONCLUSION Laparoscopic surgery may offer similar intraoperative, perioperative, and short-term oncological outcomes as an open oncologic extended resection for incidental gallbladder carcinoma.

Abstract
BACKGROUND Gallbladder cancer (GBC) is the most common biliary malignancy and has the worst prognosis, but aggressive surgeries [e.g., resection of the extrahepatic bile duct (EHBD), major hepatectomy and lymph node (LN) dissection] may improve long-term survival. GBC may be suspected preoperatively, identified intraoperatively, or discovered incidentally on histopathology.
AIM To present our data together with a discussion of the therapeutic strategies for GBC.
METHODS We retrospectively investigated nineteen GBC patients who underwent surgical treatment.
RESULTS Nearly all symptomatic patients had poor outcomes, while suspicious or incidental GBCs at early stages showed excellent outcomes without the need for two-stage surgery. Lymph nodes around the cystic duct were reliable sentinel nodes in suspicious/incidental GBCs. Intentional LN dissection and EHBD resection prevented metastases or recurrence in early-stage GBCs but not in advanced GBCs with metastatic LNs or invasion of the nerve plexus. All patients with positive surgical margins (e.g., the biliary cut surface) showed poor outcomes. Hepatectomies were performed in sixteen patients, nearly all of which were minor hepatectomies. Metastases were observed in the left-sided liver but not in the caudate lobe. We may need to reconsider the indications for major hepatectomy, minimizing its use except when it is required to accomplish negative bile duct margins. Only a few patients received neoadjuvant or adjuvant chemoradiation. There were significant differences in overall and disease-free survival between patients with stages ≤ IIB and ≥ IIIA disease. The median overall survival and disease-free survival were 1.66 and 0.79 years, respectively.
CONCLUSION Outcomes for GBC patients remain unacceptable, and improved therapeutic strategies, including neoadjuvant chemotherapy, optimal surgery and adjuvant chemotherapy, should be considered for patients with advanced GBCs.

Feasibility and Safety of Laparoscopic Treatment for Early and T3 Stage Gallbladder Cancer: A Systematic Review. Surg Laparosc Endosc Percutan Tech 2020; 31:113-123.

Abstract
BACKGROUND Effect of laparoscopic approach in the treatment of gallbladder cancer (GBC) is still controversial. MATERIALS AND METHODS Literature published before December 2019 was retrieved from PubMed, EMBASE, and Cochrane Library databases for a comparative study between laparoscopic group (LG) and open group (OG) for GBC. Revman 5.3 statistical software was used for analysis. RESULTS Nine comparative studies were eligible and included 654 patients, 287 were in LG and 367 were in OG. Meta-analysis showed that the operation time, estimated blood loss, drainage tube time, and hospitalization time after LG were significantly less than those in the OG [weighted mean difference (WMD)=-27.5; 95% confidence interval (CI), -36.6 to -18.4; P<0.00001; WMD=-267.56, 95% CI, -372.25 to -162.86; P<0.00001; WMD=-1.35; 95% CI, -2.26 to -0.44; P=0.004; WMD=-6.44; 95% CI,-9.07 to -3.81; P<0.00001, respectively). There was no significant difference between LG and OG in postoperative complications, mortality, lymph node dissection, R0 rate, scar recurrence, recurrence, and the 3- and 5-year overall survival (OS) rates. The 1-year OS of all patients, and the 1- and 2-year OS of patients with T3 tumors in the LG were significantly better than those in the OG [relative risk (RR)=1.11; 95% CI, 1.01 to 1.22; P=0.04; RR=1.46; 95% CI, 1.03 to 2.08, P=0.04 and RR=1.71; 95% CI, 1.02 to 2.84; P=0.04, respectively]. CONCLUSIONS The safety and efficacy of LG for early GBC is comparable to OG, and to some extent, it can reduce operation time, estimated blood loss, drainage tube time, and hospitalization time, and have a higher 1-year OS. Patients in T3 stage may have a longer survival by LC, however, this conclusion still needs to be validated by more high-quality clinical studies, especially prospective randomized controlled trials.

Abstract
BACKGROUND Gallbladder carcinoma (GBC) is the most common biliary tract malignancy, which is characterized by easy local invasion, lymph nodes metastasis, local vascular invasion. Hence, minimally invasive surgery (MIS) can be performed in a limited number of patients. In our study, we reviewed the current studies on laparoscopic surgery (LS) and robotic surgery (RS) for GBC and analysed the limitations and difficulties of MIS for GBC. METHODS Multiple electronic databases were used for a systematic literature retrieval. All studies involving MIS of GBC were included (up to August 2019). RESULTS A total of 24 studies were included, of which 18 studies involved LS for GBC and six studies concerned RS of GBC. For LS, 16 studies contained relevant information of T stage, and 323 patients (98.8%) had T3 or lower stage; the average rate of R0 resection, conversion, postoperative complications and mortality was 95.3% (range 80.5-100%), 1.9% (range 0-16.7%), 13.4% (range 0-33.3%) and 1.0% (range 0-10%), respectively. For RS, four studies contained relevant information of T stage, and all patients were T3 or lower stage; the average rate of R0 resection, conversion and postoperative complications was 96.8% (range 81.8-100%), 5.5% (range 0-14.8%) and11.9% (range 0-36.4%), respectively. In addition, no patient had perioperative mortality. CONCLUSIONS MIS for GBC is limited to highly selected patients and is considered to be technically feasible in experienced surgeons. However, improvements in technical and instrumental are needed to reduce the associated postoperative complications and implantation metastasis, and to promote MIS in the treatment of GBC.

Abstract
Although guidelines recommend extended surgical resection, radical resection and lymphadenectomy for patients with tumor stage (T)1b gallbladder cancer, these procedures are substantially underutilized. This population‐based, retrospective cohort study aimed to evaluate treatment patterns and outcomes of 401 patients using the US Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2013. Results showed that median overall survival (OS) was 69 months for lymphadenectomy patients and 37 months for those without lymphadenectomy. Lymphadenectomy also tended to prolong cancer‐specific survival (CSS), although the differences were not statistically significant. OS and CSS were similar for patients who received simple cholecystectomy and extended surgical resection. Cox proportional hazards regression models revealed survival advantages in patients with stage T1bN0 gallbladder cancer compared to those with stage T1bN1, and patients who received simple cholecystectomy plus lymphadenectomy compared to those who did not receive lymph node dissection. In further analyses, patients undergoing simple cholecystectomy who had five or more lymph nodes excised had better OS and CSS than those without lymph node dissection. In conclusion, survival advantages are shown for patients with T1b gallbladder cancer undergoing surgeries with lymphadenectomy. Future studies with longer follow‐up and control of potential confounders are highly warranted.

Abstract
BACKGROUND The safety and oncological efficacy of laparoscopic re-resection of incidental gallbladder cancer have not been studied. This study aimed to compare laparoscopic with open re-resection of incidentally discovered gallbladder cancer while minimizing selection bias. METHODS This was a multicentre retrospective observational cohort study of patients with incidental gallbladder cancer who underwent re-resection with curative intent at four centres between 2000 and 2017. Overall survival (OS) and recurrence-free survival (RFS) were analysed by intention to treat. Inverse probability of surgery treatment weighting using propensity scoring was undertaken. RESULTS A total of 255 patients underwent re-resection (190 open, 65 laparoscopic). Nineteen laparoscopic procedures were converted to open operation. Surgery before 2011 was the only factor associated with conversion. Duration of hospital stay was shorter after laparoscopic re-resection (median 4 versus 6 days; P < 0·001). Three-year OS rates for laparoscopic and open re-resection were 87 and 62 per cent respectively (P = 0·502). Independent predictors of worse OS were residual cancer found at re-resection (hazard ratio (HR) 1·91, 95 per cent c.i. 1·17 to 3·11), blood loss of at least 500 ml (HR 1·83, 1·23 to 2·74) and at least four positive nodes (HR 3·11, 1·46 to 6·65). In competing-risks analysis, the RFS incidence was higher for laparoscopic re-resection (P = 0·038), but OS did not differ between groups. Independent predictors of worse RFS were one to three positive nodes (HR 2·16, 1·29 to 3·60), at least four positive nodes (HR 4·39, 1·96 to 9·82) and residual cancer (HR 2·42, 1·46 to 4·00). CONCLUSION Laparoscopic re-resection for selected patients with incidental gallbladder cancer is oncologically non-inferior to an open approach. Dissemination of advanced laparoscopic skills and timely referral of patients with incidental gallbladder cancer to specialized centres may allow more patients to benefit from this operation.

Prospective multi-center study of surgeon's assessment of the gallbladder compared to histopathological examination to detect incidental malignancy. Langenbecks Arch Surg 2019; 404:573-579.

Abstract
PURPOSE Routine histopathological examination after cholecystectomy for gallstones is performed despite the low rates of incidental findings of malignancy. The aim of this study was to assess predictive values of macroscopic examination of cholecystectomy specimens by surgeons in gallstone disease. METHODS A prospective multi-center diagnostic study was carried out between December 2015 and March 2017 at four different centers. All patients undergoing cholecystectomy for gallstone disease were consecutively screened for eligibility. Patients whose ages are 18 to 80 years, and preoperative imaging findings without any pathology except cholelithiasis were included. The gallbladder was first evaluated macroscopically ex situ by two operating surgeons and rated as macroscopically benign (group S1), suspicious for a benign diagnosis (group S2), and suspicious for malignancy (group S3). Thereafter, a pathologist made a final histopathological examination whose results are grouped as chronic cholecystitis (group P1), benign or precancerous lesions in which only cholecystectomy is the adequate treatment modality (group P2), and carcinoma (group P3). Diagnostic accuracy of the surgeon's assessment to the histopathological examination was evaluated using sensitivity, specificity, positive and negative predictive values, and accuracy, and correlated by a kappa agreement coefficient. RESULTS A total of 1112 patients were included in this trial. The specificity rates were 96.5%, 100%, and 98.7% for group S1-group S2, group S1-group S3, and group S2-group S3, respectively. Accuracy rates to detect malignancy were 100% and 95. 2% for group S1 and group S2, respectively. Kappa coefficient values were 1.0 and 0.64 for group S1-group S3 and group S2-group S3, respectively (p < 0.001 for both). CONCLUSION Assessment of the gallbladder specimen and selective histopathological examination may be adequate after cholecystectomy for gallstone diseases. Such a procedure would have the potential to reduce costs and prevent unnecessary loss of labor productivity without affecting patients' safety. However, higher number of patients in more centers is needed to confirm this hypothesis.

Abstract
BACKGROUND Despite the increasing number of reports on the favorable outcomes of laparoscopic surgery for gallbladder cancer (GBC), there is no consensus regarding this surgical procedure. OBJECTIVE The study aimed to develop a consensus statement on the application of laparoscopic surgery for GBC based on expert opinions. METHODS A consensus meeting among experts was held on September 10, 2016, in Seoul, Korea. RESULTS Early concerns regarding port site/peritoneal metastasis after laparoscopic surgery have been abated by improved preoperative recognition of GBC and careful manipulation to avoid bile spillage. There is no evidence that laparoscopic surgery is associated with decreased survival compared with open surgery in patients with early-stage GBC if definitive resection during/after laparoscopic cholecystectomy is performed. Although experience with laparoscopic extended cholecystectomy for GBC has been limited to a few experts, the postoperative and survival outcomes were similar between laparoscopic and open surgeries. Laparoscopic reoperation for postoperatively diagnosed GBC is technically challenging, but its feasibility has been demonstrated by a few experts. CONCLUSIONS Laparoscopic surgery for GBC is still in the early phase of the adoption curve, and more evidence is required to assess this procedure.

Abstract
BACKGROUND Favorable outcomes of laparoscopic surgery for gallbladder cancer (GBC) have been reported; yet consensus on the indications and surgical techniques for laparoscopic surgery for GBC is lacking. OBJECTIVE To evaluate the current status of laparoscopic surgery for GBC by analyzing the results of a survey of experts and by reviewing the relevant published literature. METHODS Before an expert meeting was held on September 10, 2016 in Seoul, Korea, an international survey was undertaken of expert surgeons in the field of GBC surgery. RESULTS The majority of surgeons who responded agreed that laparoscopic surgery has an acceptable role for suspicious or early GBC, and that laparoscopic extended cholecystectomy has a value comparable to that of open surgery in selected patients with GBC. However, the selection criteria for laparoscopic surgery for overt GBC and the details of the surgical techniques varied among surgeons. CONCLUSIONS This survey and literature review revealed that laparoscopic surgery for GBC is performed in highly selected cases. However, the favorable outcomes in the published reports and the positive view of experienced surgeons for this operative procedure suggest a high likelihood that laparoscopic surgery will be more frequently performed for GBC in the future.

Abstract
Background: Laparoscopic hepatic bisegmentectomy (s4b and s5) with regional lymphadenectomy (LHBRL) for patients with gallbladder cancer (GBC) is rarely reported. Aims: The aim of the study was to describe the technique of LHBRL in patients with GBC and to present our initial experience. Patients and Methods: This retrospective study was conducted on twenty patients with GBC who were considered for LHBRL by the described technique. These patients either had a suspicion of GBC (SGBC) or had an incidental diagnosis of GBC (IGBC). Appropriate statistical methods were applied. Results: Twelve patients (60%) had SGBC and eight patients (40%) had IGBC. Eighteen patients (90%) were females and median age was 50 (range: 28–70) years. Median (range) surgical blood loss was 120 ml (80–400), operation time was 300 (200–480) min and hospital stay was 5.5 (2–10) days. No patient had iatrogenic complication during LHBRL. Five (25%) patients required conversion to open method. Four patients (20%) who developed complications were managed conservatively. All but three patients (25%) with SGBC had a benign disease on final biopsy. TNM stage of 17 patients (85%) with adenocarcinoma was T1bN0 in 3 (17.6%), T2N0 in 6 (35.3%), T3N0 in 2 (11.7%) and T1-3N1 in 6 (35.3%). The median lymph node count was 10 (range: 4–24) and resection margins were negative (R0) in all. The overall survival was 82.3%. During a median follow-up of 22 months, two patients died due to disease recurrence and one patient died due to myocardial infarction. Conclusion: The described technique of LHBRL is safe and feasible for patients with GBC without extrahepatic involvement.

Abstract
AIM To evaluate the technical feasibility and oncologic safety of laparoscopic radical cholecystectomy (LRC) for primary or incidental early gallbladder cancer (GBC) treatment. METHODS Articles reporting LRC for GBC were reviewed from the first case reported in 2010 to 2015 (129 patients). 116 patients had a preoperative diagnosis of gallbladder cancer (primary GBC). 13 patients were incidental cases (IGBC) discovered during or after a laparoscopic cholecystectomy. RESULTS The majority of patients who underwent LRC were pT2 (62.7% GBC and 63.6% IGBC). Parenchyma-sparing operation with wedge resection of the gallbladder bed or resection of segments IVb-V were performed principally. Laparoscopic lymphadenectomy was carried out according to the reported depth of neoplasm invasion. Lymph node retrieved ranged from 3 to 21. Some authors performed routine sampling biopsy of the inter-aorto-caval lymph nodes (16b1 station) before the radical treatment. No postoperative mortality was documented. Discharge mean day was POD 5th. 16 patients had post operative morbidities. Bile leakage was the most frequent post-operative complication. 5 y-survival rate ranged from 68.75 to 90.7 months. CONCLUSION Laparoscopy can not be considered as a dogmatic contraindication to GBC but a primary approach for early case (pT1b and pT2) treatment.

Abstract
Background. For Tis and T1a gallbladder cancer (GbC), laparoscopic cholecystectomy can provide similar survival outcomes compared to open cholecystectomy. However, for patients affected by resectable T1b or more advanced GbC, open approach radical cholecystectomy (RC), consisting in gallbladder liver bed resection or segment 4b-5 bisegmentectomy, with locoregional lymphadenectomy, is considered the gold standard while minimally invasive RC (MiRC) is skeptically considered. Aim. To analyze current literature on perioperative and oncologic outcomes of MiRC for patients affected by GbC. Methods. A Medline review of published articles until June 2016 concerning MiRC for GbC was performed. Results. Data relevant for this review were presented in 13 articles, including 152 patients undergoing an attempt of MiRC for GbC. No randomized clinical trial was found. The approach was laparoscopic in 147 patients and robotic in five. Conversion was required in 15 (10%) patients. Postoperative complications rate was 10% with no mortality. Long-term survival outcomes were reported by 11 studies, two of them showing similar oncologic results when comparing MiRC with matched open RC. Conclusions. Although randomized clinical trials are still lacking and only descriptive studies reporting on limited number of patients are available, current literature seems suggesting that when performed at highly specialized centers, MiRC for GbC is safe and feasible and has oncologic outcomes comparable to open RC.

Abstract
Gallbladder cancer is the most common tumor of the biliary tract and it is associated with a poor prognosis. Unexpected gallbladder cancer is a cancer incidentally discovered, as a surprise, at the histological examination after cholecystectomy for gallstones or other indications. It is a potentially curable disease, with an intermediate or good prognosis in most cases. An adequate surgical strategy is mandatory to improve the prognosis and an adjunctive radical resection may be required depending on the depth of invasion. If the cancer discovered after cholecystectomy is a pTis or a pT1a, a second surgical procedure is not mandatory. In the other cases (pT1b, pT2 and pT3 cancer) a re-resection (4b + 5 liver segmentectomy, lymphadenectomy and port-sites excision in some cases) is required to obtain a radical excision of the tumor and an accurate disease staging. The operative specimens of re-resection should be examined by the pathologist to find any “residual” tumor. The “residual disease” is the most important prognostic factor, significantly reducing median disease-free survival and disease-specific survival. The other factors include depth of parietal invasion, metastatic nodal disease, surgical margin status, cholecystectomy for acute cholecystitis, histological differentiation, lymphatic, vascular and peri-neural invasion and overall TNM-stage.

Abstract
Laparoscopic surgery has been widely accepted as a feasible and safe treatment modality in many cancers of the gastrointestinal tract. However, most guidelines on gallbladder cancer (GBC) regard laparoscopic surgery as a contraindication, even for early GBC. This study aims to evaluate and compare recent surgical outcomes of laparoscopic and open surgery for T1(a,b) GBC and to determine the optimal surgical strategy for T1 GBC.The study enrolled 197 patients with histopathologically proven T1 GBC and no history of other cancers who underwent surgery from 2000 to 2014 at 3 major tertiary referral hospitals with specialized biliary-pancreas pathologists and optimal pathologic handling protocols. Median follow-up was 56 months. The effects of depth of invasion and type of surgery on disease-specific survival and recurrence patterns were investigated.Of the 197 patients, 116 (58.9%) underwent simple cholecystectomy, including 31 (15.7%) who underwent open cholecystectomy and 85 (43.1%) laparoscopic cholecystectomy. The remaining 81 (41.1%) patients underwent extended cholecystectomy. Five-year disease-specific survival rates were similar in patients who underwent simple and extended cholecystectomy (96.7% vs 100%, P = 0.483), as well as being similar in patients in the simple cholecystectomy group who underwent open and laparoscopic cholecystectomy (100% vs 97.6%, P = 0.543). Type of surgery had no effect on recurrence patterns.Laparoscopic cholecystectomy for T1 gallbladder cancer can provide similar survival outcomes compared to open surgery. Considering less blood loss and shorter hospital stay with better cosmetic outcome, laparoscopic cholecystectomy can be justified as a standard treatment for T1b as well as T1a gallbladder cancer when done by well-experienced surgeons based on exact pathologic diagnosis.
