Intra-hepatic arterio-venous fistula after penetrating liver injury

Arterio-portal fistula occurs relatively frequently after liver trauma; its treatment is well codified. We present here in the case of a patient with an intraparenchymal fistula between a hepatic artery branch and the right hepatic vein. Embolization via interventional radiology was considered at high risk. However, hepatic necrosis developed, leading to the performance of a right lobectomy. The literature on this type of arterio-venous fistula is scanty making it difficult to propose specific management recommendations.

Impact of cirrhosis in patients undergoing laparoscopic liver resection in a nationwide multicentre survey

BACKGROUND

The aim was to analyse the impact of cirrhosis on short-term outcomes after laparoscopic liver resection (LLR) in a multicentre national cohort study.

METHODS

This retrospective study included all patients undergoing LLR in 27 centres between 2000 and 2017. Cirrhosis was defined as F4 fibrosis on pathological examination. Short-term outcomes of patients with and without liver cirrhosis were compared after propensity score matching by centre volume, demographic and tumour characteristics, and extent of resection.

RESULTS

Among 3150 patients included, LLR was performed in 774 patients with (24·6 per cent) and 2376 (75·4 per cent) without cirrhosis. Severe complication and mortality rates in patients with cirrhosis were 10·6 and 2·6 per cent respectively. Posthepatectomy liver failure (PHLF) developed in 3·6 per cent of patients with cirrhosis and was the major cause of death (11 of 20 patients). After matching, patients with cirrhosis tended to have higher rates of severe complications (odds ratio (OR) 1·74, 95 per cent c.i. 0·92 to 3·41; P = 0·096) and PHLF (OR 7·13, 0·91 to 323·10; P = 0·068) than those without cirrhosis. They also had a higher risk of death (OR 5·13, 1·08 to 48·61; P = 0·039). Rates of cardiorespiratory complications (P = 0·338), bile leakage (P = 0·286) and reoperation (P = 0·352) were similar in the two groups. Patients with cirrhosis had a longer hospital stay than those without (11 versus 8 days; P = 0·018). Centre expertise was an independent protective factor against PHLF in patients with cirrhosis (OR 0·33, 0·14 to 0·76; P = 0·010).

CONCLUSION

Underlying cirrhosis remains an independent risk factor for impaired outcomes in patients undergoing LLR, even in expert centres.

Herniation of the broad ligament… And the other side?

•

Internal hernia is a classical cause of small bowel obstruction but remains rare.

•

Discuss the appropriate management of internal hernia.

•

Broad ligament hernias account for less than 5% of internal hernia.

•

When performing surgery for broad ligament hernia, consider looking for contralateral hernia.

Introduction

Broad ligament herniation is a very uncommon cause of small bowel obstruction. Surgery permits reduction of the hernia and closure of the defect to prevent recurrence.

Presentation of case

We report a rare case of a 35 year old woman admitted in our hospital for recurrence of a small-bowel obstruction, secondary to internal hernia. The patient underwent intestinal resection in 2018 for herniated left broad ligament of the uterus strangulated.

This time, the computed tomography revealed a double junctional syndrome with ileal dilation localized in right side of uterus. Emergency surgery confirmed internal hernia with passage of ileal loops through the right broad ligament. After reduction of the hernia, closure of the defect was performed to prevent recurrence. For the first time, a check of other classic abdominal hernias was carried out.

Discussion

Internal hernias are responsible for less than 5% of mechanical bowel obstruction. Broad ligament hernias represent only 4–7% of these hernias.

The diagnosis is often delayed, because of its rarity and lack of surgical history. Surgery confirms the diagnosis, treats the occlusion and prevents recurrence.

The presence of several internal hernias has never been studied and no recommendation has been made on this topic.

Conclusion

This case demonstrate the importance of a systematic exploration of other internal abdominal hernias during the surgery, especially a contralateral broad ligament hernia.
