Waiting for bile duct dilation before repair of bile duct injury: a worthwhile strategy?

BACKGROUND: Hepaticojejunostomy (HJ) is the gold standard procedure for repairing major bile duct injury (BDI). Dilation status of the BD before repair has not been assessed as a risk factor for anastomotic stricture. METHOD: This retrospective single-centre study was performed on a population of 87 patients with BDI repaired by HJ between 2007 and 2021. Dilation status was assessed preoperatively, and dilation was defined as the presence of visible peripheral intrahepatic BDs with remaining BD diameter > 8 mm. The short- and long-term outcomes of HJ were assessed according to preoperative dilation status. RESULTS: Before final repair, the BDs were dilated (dBD) in 56.3% of patients and not dilated (ND) in 43.7%. Patients with ND at the time of repair had more severe BDI injury than those with dBD (94.7% vs. 77.6%, p = 0.026). The rate of preoperative cholangitis was lower in patients with ND than in those with dBD (10.5% vs. 44.9%, p = 0.001). The rate of short-term morbidity after HJ was 33.3% (ND vs. dBD: 38.8% vs. 26.3%, p = 0.32). Long-term anastomotic stricture rate was 5.7% with a mean follow-up period of 61.3 months. There were no differences in long-term biliary complications according to dilation status (ND vs. dBD: 12.2% vs. 10.5%, p = 1). CONCLUSION: Dilation status of the BD before HJ for BDI seemed to have no impact on short- or long-term outcomes. Both surgical and radiological external biliary drainages after BDI appear to be acceptable options to reduce cholangitis before repair without increasing risk for long-term anastomotic stricture.

Preemptive wirsungostomy: a safe fistula for avoiding a dreadful fistula in elective or planned pancreatoduodenectomy.

BACKGROUND: High-risk pancreatic anastomosis can lead to a high mortality rate after PD due to the development of postoperative pancreatic fistula (POPF). Performing a wirsungostomy by externalizing the pancreatic duct is a poorly known alternative to anastomosis which could reduce the risk of POPF and the associated severe morbidity METHODS: We retrospectively evaluated patients who underwent primary wirsungostomy with PD from January 2007 to December 2021 in our tertiary referral center. Rates of morbidity and mortality with long-term pancreatic functions were studied. RESULTS: Sixty patients were included. The median Updated Alternative Fistula Risk Score (ua-FRS) was 52%, with 95% patients in the high-risk ua-FRS category and 88.3% patients with stage D risk of developing POPF according to the classification of the ISGPS. The mortality rate was 3.3%, and overall 90-day postoperative morbidity was 63.7% with 50% of patients developing major complications. Mean follow-up was 29.8 months. Twelve patients (20%) became diabetic and 35 patients (58.3%) had preserved pancreatic endocrine function CONCLUSION: Preemptive wirsungostomy with PD could be an appropriate procedure for patients with high-risk pancreatic anastomosis. The high associated morbidity could be compromised by the low mortality and preservation of endocrine function compared to total pancreatectomy or severe POPF.

The feasibility of implementing an enhanced recovery programme in patients undergoing pelvic exenteration.

BACKGROUND: Pelvic exenteration (PE) is a complex operative procedure, reserved for patients with locally advanced and recurrent pelvic malignancies. PE is associated with a high index of post-operative morbidity. Enhanced Recovery After Surgery (ERAS) programmes have been successful in improving postoperative outcomes, however, its application in PE has not been studied. The aim of our study is to assess the feasibility and short-term impact of ERAS on PE. METHODS: A dedicated PE ERAS programme was developed reflecting the complexity of differing subtypes of PE. A prospective cohort study was undertaken to evaluate the feasibility of implementing our PE ERAS between 2016 and 2020. The primary endpoint of this study was overall compliance with the ERAS programme. RESULTS: 145 patients were enrolled into our PE ERAS programme, with 86 (56.2%) patients undergoing a soft tissue PE, 27 (17.6%) a vascular PE and 32 (20.9%) a bony PE. The median overall compliance to the PE ERAS programme was 70% (IQR 55.5-88.8). There were no observed differences between overall compliance to the PE ERAS programme between different subtypes of PE (p = 0.60). Patients with higher compliance with the PE ERAS programme had a shorter LoS (p < 0.001), less post-operative morbidity (p < 0.001), reduced severity of Clavien-Dindo grade of morbidity (p < 0.001) and fewer readmissions (p = 0.03). CONCLUSIONS: The principles of ERAS can be readily applied to patients undergoing PE, with high adherence to the ERAS programme associated with improved clinical outcomes.

Adjuncts to the Management of Graft Aorto-Enteric Erosion and Fistula with in situ Reconstruction.

OBJECTIVE: The objective of this retrospective single centre study was to determine whether different enteric reconstruction methods and adjuncts confer a benefit after in situ reconstructions (ISRs) of graft aorto-enteric erosion (AEnE) and fistula (AEnF). METHODS: Primary endpoints were in hospital mortality and AEnE/F recurrence. Survival was estimated using the Kaplan-Meier method and explanatory factors were searched for using uni- ± multivariable Cox regression analysis. In 2013, a multidisciplinary team meeting was convened and since then the primary operator has always been a senior surgeon. RESULTS: Sixty-six patients were treated for AEnE (n = 38) and AEnF (n = 28, 42%) from 2004 to 2020. All patients with AEnF presented with gastrointestinal bleeding (vs. 0 for AEnE; p < .001). Signs of infection were seen in 50 patients (76% [37 for AEnE vs. 13 for AEnF]; p < .001). Referrals for endograft infection increased over time (n = 15, 23%; one before 2013 vs. 14 after; p = .002). Most patients underwent complete graft excision (n = 52, 79%) with increasing suprarenal cross clamping (n = 21, 32%; four before 2013 vs. 17 after; p = .015). Complex visceral reconstructions decreased over time (n = 31, 47%; 17 before 2013 vs. 14 after; p = .055), while "open abdomens" (OAs) increased (one before 2013 vs. 22 after; p < .001), reducing operating time (p = .012). In hospital mortality reached 42% (n = 28). Estimated survival reached 47.6% (95% confidence interval [CI] 35.0 - 59.1) at one year and 45.6% (95% CI 33.0 - 57.3) at three years and was higher for AEnE than for AEnF (log rank p = .029). AEnE/F recurrence was noted in 12 patients (18%). Older age predicted in hospital mortality in multivariable analysis (p = .034). AEnE/F recurrence decreased with the presence of a primary senior surgeon (vs. junior; p = .003) and OA (1 [4.4%] vs. 11 [26%] for primary fascial closure; p = .045) in univariable analysis. CONCLUSION: Mortality and recurrence rates remain high after ISR of AEnE/F. Older age predicted in hospital mortality. Primary closure of enteric defects ≤ 2 cm in diameter reduced operating time without increasing the recurrence of AEnF.
