Background. The role of preoperative biliary stenting (PBS) before pancreaticoduodenectomy (PD) in patients with obstructive jaundice is debatable. The objective of the current study was to assess PD outcomes after upfront surgery or PBS and determine the impact of stent to surgery duration on PD outcomes. Methods. We reviewed patients who underwent PD between 2011 and 2019. Patients were grouped based on whether they underwent upfront surgery (n = 67) or PBS (n = 66). We further assessed outcomes based on stent to surgery duration. Results. There was no significant difference in 30-day mortality (3% vs. 2.9%, P = 1), 90-day mortality (7.5% vs. 4.4%, P = .4), and Grade B-C pancreatic fistula rates (7.5% vs. 4.4%, P = .4) in the PBS and upfront surgery groups, respectively. A significant increase in wound infections (22.7% vs. 7.4%, P = .01) and readmissions (10.6% vs. 0, P = .006) was seen in the PBS group. The highest rate of wound infection was seen when stent to surgery duration was 4-6 weeks (41.6%). The wound infection rates in the upfront surgery group, high-risk PBS group (4-6 weeks), and low-risk PBS group were 5/67(7.4%), 5/12(41.6%), and 7/36(19.4%), respectively ( P = .008). Conclusions. PBS increases postoperative wound infections when compared with upfront surgery. Patients operated between 4 and 6 weeks after stenting have the highest rate of wound infection.

Objective: Pancreaticodoudenectomy (PD) remains a challenging surgical procedure. PD outcomes remain under reported from Pakistan. The objective of the current study was to report PD outcomes from a large single center patient cohort. Methods: A total of 155 patients who underwent PD between 2011 and 2019 were included. Outcome was assessed based on morbidity, in hospital mortality and survival. Results: Mean age was 56.8 ±13.5 years (range=8-85). Male to female ratio was (103/52)1.9:1. Overall morbidity was 84/155 (54.2%). Grade B and C pancreatic fistula (PF) were seen in 5 (3.2%) and 6 (3.8%) patients. In hospital mortality was 5/155 (3.2%). The estimated 5 year overall survival (OS) was 11% and 23% for pancreatic and non-pancreatic cancers (P=0.2). The estimated 3 year OS was lower with multivisceral resection (23% vs 5%, P <0.001), advanced tumors (40% vs 11%)(P=0.008) , nodal involvement (34% vs 12%)(P=0.04) and positive microscopic margins (30% vs 8%, P=0.006). Conclusion: Short and long term outcomes comparable to international high volume centers for PD can be achieved with site specific focus in hepatopancreatobiliary surgery. Continuous...

BackgroundRole of preoperative biliary stenting (PBS) before pancreaticodoudenectomy (PD) in patients with obstructive jaundice is debatable. The objective of the current study was to assess outcomes after PD in patients who underwent upfront surgery or PBS and determine the impact of stent to surgery duration on outcomes after PD. Methods We reviewed 147 patients who underwent PD between 2011 and 2019. Patients were grouped based on whether they underwent upfront surgery (N=76) or PBS (N=71). We further assessed outcomes based on stent to surgery interval < 4 weeks or > 4 weeks. We looked at 30 and 90 day morbidity and mortality rates in these patients.Results A significant increase in wound infections (7% vs 25%)(P=0.003), overall infectious complications (22.5% vs 38.1%)(P=0.04), re admissions (0 vs 10.5%)(P=0.005) and hospital stay (9 vs 10 days)(P=0.006) was seen in the PBS group. There was no significant difference in 30 day mortality (2.8 % vs 6.5%)(P=0.4). When compared with upfront surgery group, patients with stent to surgery duration > 4 weeks had higher rates of wound infection (7% vs 29%)(P=0.009), sepsis (11.2% vs 29%)(P=0.02), overall infectious complications (22.5% vs 45.1%)(P=0.02), re admissions (0 vs 12.9%) (P=0.007) and hospital stay (9 vs 10 days)(P=0.03). The lowest rate of infectious complications was seen when PD was performed within 2 weeks (22.2%) or 6-8 weeks (12.5%) after stenting. None of the patients with stent-surgery duration < 2 weeks developed sepsis. ConclusionsPBS appears to increase infection related morbidity after PD. In patients with PBS, low morbidity is seen with early (< 2 weeks) and delayed PD (6-8weeks).
