Use of an autologous liver round ligament flap zeros postoperative bile leak after curative resection of hilar cholangiocarcinoma

Applications of hepatic round ligament/falciform ligament flap and graft in abdominal surgery-a review of their utility and efficacy

BACKGROUND AND PURPOSE

Despite their ubiquitous presence, easy availability and diverse possibilities, falciform ligament and hepatic round ligament have been used less frequently than their potential dictates. This article aims to comprehensively review the applications of hepatic round ligament/falciform ligament flap and graft in abdominal surgery and assess their utility and efficacy.

METHODS

Medical literature/indexing databases were searched, using internet search engines, for pertinent articles and analysed.

RESULTS

The studied flap and graft have found utility predominantly in the management of diaphragmatic hernias, gastro-oesophageal reflux disease, peptic perforations, biliary reconstruction, venous reconstruction, post-operative pancreatic fistula, post-pancreatectomy haemorrhage, hepatic cyst cavity obliteration, liver bleed, sternal dehiscence, splenectomy, reinforcement of aortic stump, feeding access, diagnostic/therapeutic access into portal system, composite tissue allo-transplant and ventriculo-peritoneal shunting where they have exhibited the desired efficacy.

CONCLUSIONS

Hepatic round ligament/falciform ligament flap and graft are versatile and have multifarious applications in abdominal surgery with some novel and unique uses in hepatopancreaticobiliary surgery including liver transplantation. Their evident efficacy needs wider adoption to realise their true potential.

Clinical practice of basin-shaped hepaticojejunostomy following hilar resection of stage III/IV hilar cholangiocarcinoma

Background

Radical surgery for Bismuth type III/IV hilar cholangiocellular carcinoma, which was usually considered unresectable, seems to improve prognosis by increasing the surgical curability rate. However, the dilemma of multiple billiary stumps and high postoperative complication rate caused by hepato-enteric anastomosis has been the main impediment. Thus, we practiced and introduce a new technique called “basin-shaped” hepaticojejunostomy to improve the treatment.

Methods

Thirty-two cases with Bismuth type III/IV hilar cholangiocarcinoma admitted to our department from Aug. 2013 to Dec. 2015 and who underwent hilar resection and resection segment 4(or plus resection segment 1) were reconstructed by “basin-shaped” hepaticojejunostomy. The clinical data were collected and analyzed.

Results

All patients underwent successful R0 high hilar resection following basin-shaped hepaticojejunostomy and were discharged from the hospital without severe postoperative complications. The average operation time for hepato-enteric anastomosis was 42.1 ± 8.5 min. The postoperative bile leakage rate was 3.1% (1/32), and the biliary infection rate was 6.2% (2/32). Within a median follow-up of 25.6 months, none of the patients developed local recurrence around the hepato-enteric anastomosis.

Conclusions

For patients with Bismuth type III/IV hilar cholangiocellular carcinoma who underwent resection segment 4(or plus resection segment 1), basin-shaped hepaticojejunostomy was a safe, simple and valid method for bile duct reconstruction, with a relatively low incidence of postoperative complications.

Buttressing hepaticojejunostomy's with hepatic round ligament flap may be beneficial

BACKGROUND

Bile leaks and anastomotic strictures are important complications of hepaticojejunostomy (HJ). Evidence suggests that the use of hepatic round ligament (HRL) to buttress HJ may be beneficial. This study evaluates the feasibility of this approach.

METHODS

HJs performed over 2 years (Jun 2014- May 2016), with HRL reinforcement, were analyzed. Operative outcomes measured included technical difficulty, blood loss, time necessary for flap harvest, and reinforcement of HJ. The postoperative outcomes measured were the presence of bile leak and anastomotic stricture.

RESULTS

Forty-one patients (27 M: 14 F), aged 2-79 years, median age of61 years, underwent HJ with HRL buttress; 27 for periampullary/ head of the pancreas carcinoma; 4 for choledochal cysts; 4 for chronic pancreatitis; 3 for gallbladder carcinoma; 3 for benign biliary stricture. The time for harvesting HRL flaps and buttressing HJ was <10 minutes. No blood was lost during harvesting the flaps. One patient (2.5 %) had grade A leak following radical cholecystectomy, and structures were not observed during a median follow-up of 18 months (6 months to 2years).

CONCLUSION

HRL-based buttressing of HJ can reduce the bile leak and/or stricture rate.
