AI Article Synopsis
- SADF (Secondary Aortoduodenal Fistulae) are serious complications arising from aortic surgeries, with limited data on their associated risks and outcomes.
- A review of existing literature included 189 patients treated for SADF, highlighting varied surgical interventions like aortic graft excision and bowel repairs, but showed no significant difference in mortality rates based on the type of surgery performed.
- Omentoplasty, a procedure involving the addition of abdominal tissue, was found to significantly lower mortality risk, indicating that comprehensive management of both aortic and duodenal issues is crucial for better patient outcomes.
Article Abstract
Objective: Secondary aortoduodenal fistulae (SADF) are uncommon but life-threatening conditions that occur as complications of aortic reconstructive surgery. Data on the mortality and morbidity of procedures associated with SADF remain scarce.
Methods: Comprehensive literature search was conducted on the MedLine, Scopus, Embase, and Web of Knowledge databases for cases of SADF. Data regarding patient demographics, fistula anatomy and treatment interventions performed were extracted for further analysis.
Results: The study pool consisted of 127 case reports, 28 case series and 1 retrospective study published between 1973 and 2021. A total of 189 patients were operated for SADF. Among the 189 patients, 141 patients (74.6%) had aortic graft excision, 26 (13.8%) aortic primary repair, and 22 (11.6%) EVAR. Although patients undergoing EVAR were older with higher Charlson Comorbidity Index, compared with patients who had graft excision and primary aortic repair these differences were not statistically significant (P = .12 and P = .22, respectively). Primary bowel repair was performed in 145 patients (76.7%), duodenectomy in 25 (13.2%), and no bowel repair in 19 (10.1%). Additional omentoplasty was performed in 65 patients (34.6%). Mortality was comparable with respect to the type of aortic and bowel repair, with no statistically significant differences recorded (P = .54 and P = .77, respectively). Omentoplasty significantly decreased the risk of death (odds ratio, 0.4; 95% confidence interval, 0.2-0.8, P = .01).
Conclusions: Optimal operative management should address both the aortic and duodenal defects and be complemented with appropriate reconstructive procedures. Endovascular aortic approaches seem feasible in carefully select patients in whom duodenal repair may be omitted.

Purpose: This study aimed to analyze the characteristics and outcomes of patients with an aortoduodenal fistula (ADF) who underwent surgical treatment at a single institution.
Materials And Methods: The data of patients diagnosed with ADF at the Yonsei University Gangnam Severance Hospital, South Korea, between 2019 and 2022 were included. Primary repair and segmental resection of the duodenum with duodeno-jejunostomy were the two main methods used to repair ADF.

Introduction: There is a risk of iatrogenic vascular injuries during robotic-assisted laparoscopic excision of diaphragmatic endometriosis. Although studies are limited, the first reported case of a suprahepatic inferior vena cava (IVC) injury during robotic diaphragmatic endometriosis excision was successfully treated using a fibrin sealant patch, preventing exsanguination and conversion to laparotomy.
Case Description: A 36-year-old female with a history of recurrent catamenial pneumothorax and two prior video-assisted thoracoscopic surgeries to treat diaphragmatic endometriosis presented to our clinic with right-sided shoulder pain and a chest tube in place.
