Total Laparoscopic Resection of Hilar Cholangiocarcinoma Type 3b: Applying a Parachute Technique for Hepaticojejunostomy

Preoperative Endoscopic Ultrasound-Guided Hepaticogastrostomy for Definite Biliary Drainage in Hilar Cholangiocarcinoma Laparoscopic Resection: A Hybrid Minimal-Invasive Technique

BACKGROUND AND STUDY AIMS

Laparoscopic approach of perihilar cholangiocarcinoma (PHC) is still challenging. We report the original use of a endoscopic hepaticogastrostomy (EHG) for definite biliary drainage in order to avoid biliary reconstruction.

PATIENTS AND METHODS

A 70-year-old man presenting with jaundice was referred for resection of a Bismuth type IIIa PHC. Repeated endoscopic retrograde cholangiopancreatography failed to drain the future liver remnant, enabling only right anterior liver section drainage. EHG was performed three weeks before surgery. A hepatogastric anastomosis was created, placing a half-coated self-expanding endoprosthesis between biliary duct of segment 2 and the lesser gastric curvature.

RESULTS

A laparoscopic right hepatectomy extended to segment 1, common bile duct, and hepatic pedicle lymphadenectomy was performed. The left hepatic duct was sectioned and ligated downstream to the biliary confluence of segment 2-3 and 4 allowing exclusive biliary flow through the EHG. The patient was disease free at 12 months, postoperative outcomes were uneventful except three readmissions for acute cholangitis due to prosthesis obstruction.

CONCLUSIONS

EHG may be used as definite biliary drainage technique in laparoscopic PHC resection, at the expense of prosthesis obstruction and cholangitis.

Laparoscopic Resection of Perihilar Cholangiocarcinoma Type IIIb: A Video Demonstration of No-Touch En-Block Technique and Radical Lymphadenectomy

BACKGROUND

Minimally invasive surgery for perihilar cholangiocarcinoma (pCCA) is in an exploratory phase by now and is only recommended for carefully selected patients.

PATIENTS AND METHODS

Our team performed total laparoscopic hepatectomy in a 64-year-old woman with perihilar cholangiocarcinoma type IIIb. Laparoscopic left hepatectomy and caudate lobectomy were performed involving a no-touch en-block technique. Meanwhile, extrahepatic bile duct resection, radical lymphadenectomy with skeletonization, and biliary reconstruction were performed.

RESULTS

Laparoscopic left hepatectomy and caudate lobectomy were successfully performed in 320 min with 100 ml of blood loss. The histological grading was T2bN0M0 (stage II). The patient was discharged on the 5th day without postoperative complications. Following the operation, the patient received single-drug capecitabine chemotherapy. There was no recurrence after 16 months of follow-up.

CONCLUSION

Our experience is that, in selected patients with pCCA type IIIb or type IIIa, laparoscopic resection can reach comparable outcome to open surgery with standardized lymph node dissection by skeletonization, use of no-touch en-block technique, and proper digestive tract reconstruction.

Comparison of Efficacy and Safety Between Laparoscopic and Open Radical Resection for Hilar Cholangiocarcinoma—A Propensity Score-Matching Analysis

Background

Radical resection remains the most effective treatment for hilar cholangiocarcinoma (HCCA). However, due to the complex anatomy of the hilar region, the tumor is prone to invade portal vein and hepatic arteries, making the surgical treatment of HCCA particularly difficult. Successful laparoscopic radical resection of HCCA(IIIA, IIIB) requires excellent surgical skills and rich experience. Furthermore, the safety and effectiveness of this operation are still controversial.

Aim

To retrospectively analyze and compare the efficacy and safety of laparoscopic and open surgery for patients with HCCA.

Methods

Clinical imaging and postoperative pathological data of 89 patients diagnosed with HCCA (IIIA, IIIB) and undergoing radical resection in our center from January 2018 to March 2022 were retrospectively analyzed. Among them, 6 patients (4 were lost to follow-up and 2 were pathologically confirmed to have other diseases after surgery) were ruled out, and clinical data was collected from the remaining 83 patients for statistical analysis. These patients were divided into an open surgery group (n=62) and a laparoscopic surgery group (n=21) according to the surgical methods used, and after 1:2 propensity score matching (PSM), 32 and 16 patients respectively in the open surgery group and laparoscopic surgery group were remained. The demographic data, Bismuth type, perioperative data, intraoperative data, postoperative complications, pathological findings, and long-term survivals were compared between these two groups.

Results

After 1:2 PSM, 32 patients in the open surgery group and 16 patients in the laparoscopic surgery group were included for further analysis. Baseline characteristics and pathological outcomes were comparable between the two groups. Statistically significant differences between the two groups were observed in intraoperative blood loss and operative time, as it were 400-800 mL vs 200-400 mL (P=0.012) and (407.97 ± 76.06) min vs (489.69 ± 79.17) min (P=0.001) in the open surgery group and laparoscopic surgery group, respectively. The R0 resection rate of the open group was 28 cases (87.5%), and the R0 resection rate of the laparoscopic group was 15 cases (93.75%). The two groups showed no significant difference in terms of surgical approach, intraoperative blood transfusion, incidence of postoperative complications, and short- and long-term efficacy (P>0.05).

Conclusions

Laparoscopic radical resection of HCCA has comparable perioperative safety compared to open surgery group, as it has less bleeding and shorter operation time. Although it is a promising procedure with the improvement of surgical skills and further accumulation of experience, further investigations are warranted before its wider application.

Parachute technique for portal vein reconstruction during pancreaticoduodenectomy with portal vein resection in patients with pancreatic head cancer

BACKGROUND

The most appropriate venous reconstruction method remains debatable when a long section of portal vein (PV) and/or superior mesenteric vein (SMV) must be resected in patients undergoing a pancreaticoduodenectomy (PD). The aim of the present study was to describe the technical details of the parachute technique, a modified end-to-end anastomotic maneuver that can be used in the above-mentioned circumstances, and to investigate its safety and feasibility.

STUDY DESIGN

Patients who underwent venous reconstruction using the parachute technique after receiving a PD with PV resection for pancreatic cancer between January 2014 and March 2019 were retrospectively reviewed. For the parachute technique, the posterior wall was sutured in a continuous fashion while the stitches were left untightened. The stitches were then tightened from both sides after the running suture of the posterior wall had been completed, thereby dispersing the tension applied to the stitched venous wall when the venous ends were brought together and solving any problems that would otherwise have been caused by over-tension. The postoperative outcomes and PV patency were then investigated.

RESULTS

Fifteen patients were identified. The median length of the resected PV/SMV measured in vivo was 5 cm (range, 3-6 cm). The splenic vein was resected in all the patients and was reconstructed in 13 patients (87%). The overall postoperative complication rate (≥ Clavien-Dindo grade I) was 60%, while a major complication (≥ Clavien-Dindo grade IIIa) occurred in 1 patient (7%). No postoperative deaths occurred in this series. The PV patency at 1 year was 87%.

CONCLUSION

The parachute technique is both safe and feasible and is a simple venous reconstruction procedure suitable for use in cases undergoing PD when the distance between the resected PV and SMV is relatively long.

Robotic Resection of Type I Hilar Cholangiocarcinoma with Intrapancreatic Bile Duct Dissection

BACKGROUND

Type I hilar cholangiocarcinoma is a malignancy of the extrahepatic bile duct for which margin-negative resection with sufficient lymphadenectomy may provide curative treatment. The aim of this video is to highlight the advantages of optical magnification, articulating instruments, and indocyanine green fluorescent cholangiography to demonstrate extrahepatic bile duct resection from the biliary confluence to the intrapancreatic bile duct with comprehensive hilar lymphadenectomy for pathologic staging.

METHODS

A 58-year-old male presented with obstructive jaundice and was found to have a biliary stricture arising from the cystic duct and bile duct junction. Endoscopic biopsy of the bile duct confirmed adenocarcinoma. His case was presented at a multidisciplinary tumor conference where consensus was to proceed with upfront robotic en bloc extrahepatic bile duct resection with hilar lymphadenectomy and Roux-en-Y hepaticojejunostomy.

RESULTS

Final pathology demonstrated margin-negative resection of moderately differentiated adenocarcinoma, 1 out of 12 lymph nodes involved with disease, and pathologic stage T2N1M0 (stage IIIC). The patient had no postoperative complications and was discharged home on postoperative day 5. At 6 weeks from his operative date, he was initiated on four cycles of adjuvant gemcitabine/capecitabine, followed by 50 Gray external beam radiation therapy with capecitabine, then four cycles of gemcitabine/capecitabine, completed after 6 months of therapy.

CONCLUSIONS

Robotic extrahepatic bile duct resection, hilar lymphadenectomy, and biliary enteric reconstruction is feasible and should be considered for selected cases of bile duct resection.
