    ABSTRACT: Background Surgery on patients with malignant obstructive jaundice carries increased risks of postoperative morbidity and mortality. Preoperative biliary drainage has been developed to reduce this procedure-related risks, but its role in patients who are going to receive pancreaticoduodenectomy for periampullary carcinoma is still controversial. Methods This article aimed at reviewing the current status of preoperative biliary drainage for patients with peri-ampullary tumors who were candidates for pancreaticoduodenectomy. A MEDLINE and PubMed database search from 1980 to 2013 was performed to identify relevant articles using the keywords “pancreaticoduodenectomy”, “preoperative biliary drainage”, “jaundice”, “peri-ampullary neoplasm” and “carcinoma of pancreas”. Additional papers were identified by a manual search of the references from the key articles. Results There were six randomized controlled trials (RCTs) and 5 meta-analyses on preoperative biliary drainage for patients with malignant obstructive jaundice. Most of the results of these studies could not be used to define the role of preoperative biliary drainage for patients who received pancreaticoduodenectomy for periampullary carcinoma because: first, the majority of these studies were on bypass or palliative resections; second, various pathologies with both proximal and distal biliary obstruction were included; third, there were different forms of percutaneous or endoscopic drainage procedures; fourth, there were different durations of preoperative drainage; and finally, there were variations in the definition of events and outcomes. There was only one RCT which included a homogeneous group of patients with carcinoma of pancreas who underwent pancreaticoduodenectomy. For patients with periampullary tumor, the RCTS and meta-analyses showed no benefit of preoperative biliary drainage. Instead, there were some concerns about the drainage-related complications and the increase in positive intraoperative bile culture rate and the associated infective complication rate postoperatively. Conclusion Routine preoperative biliary drainage showed no beneficial effect on the surgical outcome for patients with periampullary tumor. A selective approach of preoperative biliary drainage should be adopted for these patients. The optimal duration and modality of preoperative biliary drainage remain unclear.

    ABSTRACT: Abstract Introduction: Laparoscopic liver resection under hemihepatic vascular inflow occlusion has advantages over the conventional Pringle's maneuver, especially in patients with cirrhosis. However, laparoscopic hemihepatic vascular inflow occlusion is technically challenging. Subjects and Methods: From March 2013 to August 2013, 8 consecutive patients who underwent laparoscopic liver resection under right hemivascular inflow occlusion using the lowering of the hilar plate approach. Results: There were 3 women and 5 men, with a mean age of 52.6 years (range, 44-73 years). The pathologies were hepatocellular carcinoma (n=3), sarcomatoid liver carcinoma (n=1), hepatic vascular epithelial tumor (n=1), hemangioma (n=2), and colorectal liver metastases (n=1). The types of resection included right hepatectomy (n=3), right anterior sectionectomy (n=1), segments 5 and 6 resection (n=1), and segment 6 resection (n=2). All patients underwent right hemivascular inflow occlusion. The mean operation time was 186.2 minutes (range, 100-280 minutes). The mean time taken to prepare for hemivascular inflow occlusion was 17.8 minutes (range, 15-20 minutes). The mean intraoperative blood loss was 218.8 mL (range, 100-300 mL). The mean duration of vascular control was 25.6 minutes (range, 15-40 minutes). No patients developed postoperative liver failure. There was no postoperative morbidity or mortality. The mean hospital stay was 6 days (range, 5-7 days). Conclusions: Hemihepatic vascular inflow occlusion using the lowering of the hilar plate approach was safe and feasible. It facilitated laparoscopic liver resection by minimizing blood loss during liver parenchymal transection.

    ABSTRACT: Hemoperitoneum is a rare and potentially life-threatening complication of GIST. We reported a 54-year-old man who developed disseminated intra-abdominal recurrence from a previously resected gastrointestinal stromal tumour (GIST) of the small bowel, and the patient presented with hemoperitoneum. Emergent debulking surgery was performed. A high dose imatinib was prescribed. Despite the presence of residual disease, the patient was well clinically 8 months after the operation. Even though, there is no evidence to support the routine use of debulking surgery in the management of GIST. In our patient, disease progression after second line targeted therapy and the absence of alternative treatment options for spontaneous rupture and hemoperitoneum prompted us to treat the patient aggressively. Resection of the ruptured GIST was carried out for control of bleeding and to prevent recurrent bleeding in this patient with good surgical risks. During the treatment decision-making, the patient's general condition, the risk of surgery and the extent of dissemination were taken into consideration. In this patient who presented with spontaneous rupture of a small intestinal GIST, the novel use of targeted therapy and aggressive surgical treatment produced reasonably good survival outcome.

    ABSTRACT: Techniques for reconstruction of pancreatic stump with gastrointestinal tract following pancreaticoduodenectomy are closely related to postoperative complications, mortality and quality of life. In order to reduce postoperative complications, particularly pancreatic fistula, many modifications and new surgical techniques have been proposed to replace the traditional pancreaticojejunostomy and pancreaticogastrostomy. The objective of this review, based on large prospective randomized trials and meta-analyses, is to evaluate the different techniques of enteric reconstruction of pancreatic stump following pancreaticoduodenectomy, including: invagination pancreaticojejunostomy, binding pancreaticojejunostomy, duct-to-mucosa pancreaticojejunostomy, Roux-en-Y pancreaticojejunostomy, and pancreaticogastrostomy, so as to provide a comprehensive comparison of these techniques and to assess of their roles and effectiveness.

    ABSTRACT: The aim of this randomized comparative trial (RCT) is to compare partial hepatectomy (PH) with transcatheter arterial chemoembolization (TACE) to treat patients with resectable multiple hepatocellular carcinoma (RMHCC) outside of Milan Criteria. This RCT was conducted on 173 patients with RMHCC outside of Milan Criteria (a solitary tumor up to 5 cm or multiple tumors up to 3 in number and up to 3 cm for each tumor) who were treated in our centre from November 2008 to September 2010. The patients were randomly assigned to the PH group or the TACE group. The primary outcome measure was overall survival (OS) from the date of treatment. A multivariate Cox proportional hazards regression analysis was performed to assess the prognostic risk factors associated with OS. The 1-, 2- and 3- year OS rates were 76.1%, 63.5% and 51.5%, respectively, for the PH group compared with 51.8%, 34.8% and 18.1%, respectively, for the TACE group(log-rank test,χ2=24.246,P < 0.001).Multivariate Cox proportional hazards regression analysis revealed the type of treatment (hazard ratio, 0.434; 95% CI, 0.293 to 0.644,P < 0.001), number of tumor (hazard ratio, 1.758; 95% CI, 1.213 to 2.548,P=0.003) and gender (hazard ratio, 0.451; 95% CI, 0.236 to 0.862,P=0.016) were significant independent risk factors associated with OS. PH provided better OS for patients with RMHCC outside of Milan Criteria than conventional TACE. The number of tumor and gender were also independent risk factors associated with OS for RMHCC.

    ABSTRACT: A study of 7,388 consecutive patients after hepatic resection between 2011 and 2012 identified hepatolithiasis, cirrhosis, and intraoperative blood transfusion as the only independent risk factors of both incisional and organ/space surgical site infection (SSI). Patients with these conditions should be cared for with caution to lower SSI rates.

    ABSTRACT: Massive blood loss remains a problem during resection for giant liver hemangioma. This present study was designed to compare selective hepatic vascular exclusion (SHVE) versus Pringle maneuver in surgery for liver hemangioma compressing the major (right, middle, or left) hepatic veins. From January 2003 to December 2011, 589 consecutive patients with hemangioma underwent liver resection in our department, and 273 patients had their tumors compressing at least one of the three major hepatic veins (right, middle, or left). Either SHVE (n = 120 patients) or Pringle maneuver (n = 153 patients) was used to minimize blood loss during resection. Data regarding the intraoperative and postoperative courses of these patients were retrospectively analyzed. There was no significant difference between the two groups of patients regarding age, sex, tumor size, types of hepatectomy, and extent of tumor involvement of the major hepatic veins. Intraoperative blood loss, transfusion requirements, and transfusion volume were significantly less in the SHVE group (P < 0.01). For the Pringle group, major hepatic veins were lacerated in 19 patients during hepatic parenchymal transection. For the SHVE group, a major hepatic vein was lacerated during extrahepatic dissection of the hepatic vein in two patients and during hepatic parenchymal transection in 14 patients. SHVE was more efficacious in minimizing intraoperative bleeding during liver resection for hemangiomas compressing the major hepatic veins. It prevented intraoperative major bleeding and air embolism and significantly decreased postoperative liver failure and in-hospital mortality.

    ABSTRACT: Introduction. Both hepatocellular carcinoma (HCC) presenting during pregnancy and HCC presenting with obstructive jaundice due to a tumor cast in the biliary tract are very rare. The management of these patients remains challenging. Presentation of Case. A 23-year-old lady presented with obstructive jaundice at 38 weeks of gestation. Investigations showed HCC with a biliary tumor thrombus. She received percutaneous transhepatic biliary drainage (PTBD) and caesarean section. Right hepatectomy, extrahepatic bile duct resection, and left hepaticojejunostomy were carried out when the jaundice improved. The postoperative course was uneventful. She was discharged home on postoperative day 10. Histopathology showed HCC with a tumor thrombus in the bile duct. The surgical margins were clear. One year after surgery, the mother was disease-free and the baby was well. Conclusion. With proper management, curative treatment is possible in a pregnant patient who presented with obstructive jaundice due to a biliary tumor thrombus from HCC.

    ABSTRACT: Improvements in surgical technique and perioperative care have made partial hepatectomy a safe and effective treatment for hepatocellular carcinoma (HCC), even in the event of spontaneous HCC rupture. A consecutive cohort of patients who underwent partial hepatectomy for HCC between 2000 and 2009 was divided into a ruptured group and a non-ruptured group. Patients with ruptured HCC were further divided into emergency and staged hepatectomy subgroups. Mortality and morbidity, overall survival and recurrence-free survival (RFS) were compared. Prognostic factors for overall survival and RFS were identified by univariable and multivariable analyses. A total of 1233 patients underwent partial hepatectomy for HCC, of whom 143 had a ruptured tumour. The morbidity and mortality rates were similar in the ruptured and non-ruptured groups, as well as in the emergency and staged subgroups. In univariable analyses, overall survival and RFS were lower in the ruptured group than in the non-ruptured group (both P < 0·001), and also in the emergency subgroup compared with the staged subgroup (P = 0·016 and P = 0·025 respectively). In multivariable analysis, spontaneous rupture independently predicted poor overall survival after hepatectomy (hazard ratio 1·54, 95 per cent confidence interval 1·24 to 1·93) and RFS (HR 1·75, 1·39 to 2·22). Overall survival and RFS after hepatectomy for ruptured HCC in the emergency and staged subgroups were not significantly different in multivariable analyses. Spontaneous rupture predicted poor long-term survival after hepatectomy for HCC, but surgical treatment seems possible, safe and appropriate in selected patients.

    ABSTRACT: BACKGROUND: This study aimed at analyzing the perioperative and early survival outcomes of robotic liver resection of hepatocellular carcinoma (HCC). METHODS: The study population included a consecutive series of patients with HCC who underwent robotic liver resection at a single center. RESULTS: During the study period, 41 consecutive patients with HCC underwent 42 robotic liver resections. Five resections (11.9%) were carried out for recurrent HCC, and 23.8% (n = 10) were hemihepatectomy procedures. The mean operating time and blood loss was 229.4 minutes and 412.6 mL, respectively. The R0 resection rate was 93%. The hospital mortality and morbidity rates were 0% and 7.1%, respectively. The mean hospital stay was 6.2 days. The 2-year overall and disease-free survival rates were 94% and 74%, respectively. In the subgroup analysis of minor liver resection, when compared with the conventional laparoscopic approach, the robotic group had similar blood loss (mean, 373.4 mL vs 347.7 mL), morbidity rate (3% vs 9%), mortality rate (0% vs 0%), and R0 resection rate (90.9% vs 90.9%). However, the robotic group had a significantly longer operative time (202.7 mins vs 133.4 mins). CONCLUSIONS: This study demonstrated the feasibility and safety of robotic surgery for HCC, with favorable short-term outcome. However, the long-term oncologic results remain uncertain.

    ABSTRACT: BACKGROUND: The aim of this study was to compare the results of surgical resection with three-dimensional conformal radiotherapy (3D-CRT) in the treatment of resectable hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). Transarterial chemoembolization (TACE) was given to both groups of patients when possible. METHODS: A retrospective study of 371 patients with resectable HCC with PVTT was conducted in two tertiary referral centers. The treatment of choice for these patients in one center was surgical resection. In the other center it was 3D-CRT. In the radiotherapy group (RG, n = 185), patients received 3D-CRT to the tumor and PVTT for a total radiation dose of 30-52 Gy (median 40 Gy). In the surgical group (SG, n = 186), patients underwent surgical resection. TACE was applied after surgery or 3D-CRT and then was repeated every 4-6 weeks if the patient tolerated the treatment. RESULTS: The median survival was 12.3 months for RG and 10.0 months for SG. The 1-, 2-, and 3-year overall survivals were 51.6, 28.4, and 19.9 %, respectively, for RG and 40.1, 17.0, and 13.6 %, respectively, for SG (p = 0.029). Stepwise multivariate analysis showed that the extent of PVTT and mode of treatment were independent risk factors of overall survival. The most common cause of death after treatment was liver failure as a consequence of progressive intrahepatic disease. CONCLUSIONS: 3D-CRT gave better survival than surgical resection for HCC with PVTT.

    ABSTRACT: Mirizzi syndrome is an uncommon cause of common hepatic duct obstruction resulting from gallstone impaction in the cystic duct or gallbladder neck. Mirizzi syndrome is traditionally considered as a contraindication to laparoscopic surgery mainly due to risk of bile duct injury during dissection. We present the surgical experience of 5 patients with Mirizzi syndrome who were diagnosed preoperatively and managed using minimally access surgical technique, either total laparoscopic or robotic-assisted laparoscopic approach. All patients had successful operations and recovered without complications. We concluded that with a correct preoperative diagnosis, careful operative strategy, increasing expertise with laparoscopic technique, and introduction of robotic surgical system, minimally invasive approach of management of Mirizzi syndrome becomes safe and feasible.

    ABSTRACT: BACKGROUND AND AIM: Selective hepatic vascular exclusion (SHVE) has not been widely used because of difficulty in extrahepatic isolation of hepatic veins. This study aims to compare the results of SHVE using tourniquets or Satinsky clamps on major hepatic veins in partial hepatectomy for liver tumors involving the roots of hepatic veins. METHODS: Between June 2008 and March 2012, a randomized controlled trial was performed on patients undergoing liver resection to compare selective hepatic vascular exclusion using tourniquets or Satinsky clamps in partial hepatectomy. In the tourniquet group, the hepatic veins were completely isolated and occluded with tourniquets. In the Satinsky clamp group, the hepatic veins were dissected on the anterior and side walls only and they were clamped directly by Satinsky clamps. RESULTS: The time for dissecting hepatic veins was significantly shorter in the Satinsky clamp group (7.5 ± 6.6 min vs 21.3 ± 7.4 min) than the tourniquet group. In the tourniquet group, 5 hepatic veins could not be completely isolated and encircled. In 4 additional patients the hepatic vein was slightly torn during dissection. These 9 patients received successful occlusion using Satinsky clamps. In the Satinsky group, all occlusion of the hepatic vein was successful. There was a significant difference in the success rate in hepatic vein occlusion using the Satinsky and the tourniquet groups 60/60 vs 51/60, P = 0.0018. CONCLUSIONS: Both techniques of hepatic vein occlusion were safe and efficacious. As the use of Satinsky clamps is safer, easier and took less time, it is recommended.

    ABSTRACT: BACKGROUND: To compare the results of radiofrequency ablation (RFA) with hepatic resection in the treatment of hepatocellular carcinoma (HCC) within the Milan criteria METHODS: A nonrandomized comparative study was performed with 111 consecutive patients who underwent laparoscopic RFA (n=31) or curative hepatic resection (n =80) for HCC within Milan criteria. RESULTS: Procedure related complications were less often and severe after RFA than resection (3.2% vs. 25%). There was no significant difference in hospital mortality (0% vs. 3.8%). Hospital stay was significantly shorter in the RFA group than in the resection group (mean, 3.8 vs. 6.8 days). The disease-free survival rates for the RFA group and the resection group were 76%, 40%, 40% and 76%, 60%, 60%, respectively. Disease-free survival was significantly lower in the RFA group than in the resection group. The corresponding 1-, 3-, and 5-year overall survival rates for the RFA group and the resection group were 100%, 92%, 84%, and 92%, 75%, 71%, respectively. The overall survival for RFA and resection were not significantly different. CONCLUSIONS: Our result showed comparable overall survival between RFA and surgery, although RFA was associated with a significantly higher tumor recurrence rate. RFA had the advantages over surgical resection in being less invasive and having lower morbidity.

    ABSTRACT: IntroductionThe two current standard laparoscopic approaches for inguinal hernia repair are transabdominal preperiotneal and totally extraperitoneal. Single-incision repairs have been explored in an effort to further reduce the invasiveness of the surgery. However, with single incision, surgeons need to possess special skills and require special instruments. Needlescopic inguinal hernia repair could represent a more attractive alternative. Using a transumbilical incision, an almost scarless transabdominal preperiotneal can be achieved. In the present study, we report our experience of scarless needlescopic transabdominal preperiotneal inguinal hernia repair. Patients and Methods This is a prospective analysis of a cohort of patients with inguinal hernia who underwent elective scarless needlescopic transabdominal preperiotneal repair. Patient demographic data, type of hernia, operative time, perioperative and postoperative course, pain score and final patient satisfaction score were all recorded for analysis. ResultsIn March 2011, four patients received scarless needlescopic transabdominal preperiotneal for inguinal hernia repair. Their average age was 57.25 years. The mean operative time was 79.5 min. The patients were discharged on the same day. There were no postoperative complications. Conclusion Scarless needlescopic transabdominal preperiotneal inguinal hernia repair is feasible and safe, and is well accepted by patients. Further studies will be conducted to evaluate its full potential.

    ABSTRACT: INTRODUCTION: Cancer in pregnancy is rare and hepatocellular carcinoma (HCC) during pregnancy is even rarer. Due to limited experience, management of these patients remains challenging. PRESENTATION OF CASE: A 33-year old pregnant lady presented with HCC at 28 weeks of gestation. She underwent synchronous cesarean section and right hepatectomy at 32 weeks of gestation. The post-operative course was uneventful. She was discharged home on day 10 after surgery. Histolopathology confirmed HCC. The surgical resection margins were clear. At a follow-up of 3 months after surgery, the mother was disease free and the infant was well. DISCUSSION: HCC during pregnancy is extremely rare. The experience in its management and outcomes are lacking. In managing any patient diagnosed with a malignant neoplasm in pregnancy, both the mother and the fetus have to be considered. CONCLUSION: With adequate preoperative assessment and a good management strategy, good results can be obtained for both the mother and the baby for a pregnant patient with HCC.

    ABSTRACT: OBJECTIVE:: This study aimed to clarify the incidence of hepatitis B virus (HBV) reactivation and its significance on long-term survival after partial hepatectomy in patients with HBV-related hepatocellular carcinoma (HCC), who had preoperative low HBV-DNA level of less than 2000 IU/mL. BACKGROUND:: HBV reactivation is a frequent complication of systemic chemotherapy in hepatitis B surface antigen-positive patients. Surgery and anesthesia result in a generalized state of immunosuppression in the immediate postoperative period. Data on HBV reactivation and its significance after partial hepatectomy are unclear. PATIENTS AND METHODS:: Consecutive patients from January 2006 to December 2007 were retrospectively studied. RESULTS:: HBV reactivation happened in 19.1% of patients in 1 year. There were 28 patients whose HBV reactivation was detected after the diagnosis of HCC recurrence. On multivariate analysis, hepatitis B e antigen (HBeAg) positivity, preoperative HBV-DNA above the lower limit of quantification (≥200 IU/mL), Ishak inflammation score of greater than 3, preoperative transarterial chemoembolization (TACE), operation time of more than 180 minutes, blood transfusion, and without prophylactic antiviral therapy were significantly associated with an increased risk of HBV reactivation. HBV reactivation negatively influenced postoperative hepatic functions. The posthepatectomy liver failure rate in patients with HBV reactivation was significantly higher than in those without reactivation (11.8% vs 6.4%; P = 0.002). The 3-year disease-free survival (DFS) rate and overall survival (OS) rates after resection in patients with HBV reactivation were significantly lower than those without reactivation (34.1% vs 46.0%; P = 0.009, and 51.6% vs 67.2%; P < 0.001, respectively). HBeAg positivity, detectable preoperative HBV-DNA level, high Ishak inflammation score, preoperative TACE, long operation time, and blood transfusion were independent risk factors for HBV reactivation, whereas prophylactic antiviral therapy was a protective factor. HBV reactivation, HBeAg positivity, HBV-DNA level of 200 IU/mL or more, tumor diameter greater than 5 cm, presence of satellite nodules, presence of portal vein tumor thrombus, blood transfusion, and resection margin less than 1.0 cm were independent risk factors for DFS. A HBV-DNA level of 200 IU/mL or more, an Ishak fibrosis score of 4 or greater, a tumor diameter greater than 5 cm, the presence of satellite nodules, the presence of portal vein tumor thrombus, a resection margin less than 1.0 cm, no prophylactic antiviral therapy, and HBV reactivation were independent risk factors for OS. CONCLUSIONS:: HBV reactivation was common after partial hepatectomy for HBV-related HCC with a preoperative low HBV-DNA level of less than 2000 IU/mL. Routine prophylactic antiviral treatment should be given before partial hepatectomy.
