Background: The surgical decision making for pancreatic adenocarcinoma is complex. Although practice guidelines exist for many scenarios, these do not cover many common eventualities that may be encountered during these cases. We sought to identify the practice pattern variations amongst pancreatic surgeons in response to commonly experienced clinical scenarios. Methods: A multiple-choice questionnaire was distributed to all full members of the IHPBA. Participant demographics, training history, and clinical practice information were obtained. The survey provided various operative scenarios and participants were asked how they would likely proceed. Responses were collected and stored anonymously in a secure database. Statistical analysis was performed using Stata 16.0. Results: 164 responses were submitted. Most of the respondents were male and had been in practice for over 10 years. The median age range was 40-50 years old. When asked about staging laparoscopy, the majority performed it selectively. For most respondents a pathological aorto-caval nodes was a reason to abort the procedure but most would have continued in the setting of a positive hepatic artery node. When encountering a single Segment 2 liver metastasis, participants who practiced in Europe were significantly more likely to resect and proceed compared to those in Asia and North America. Participants who had undergone only a Surgical Oncology fellowship were most likely to abort. With respect to direct colonic invasion, most participants would resect the specimen en bloc. Respondents who participated in fewer that 20 PDAC operations/year were most likely to abort. Conclusions: Surgical decision making in PDAC surgery is complex and there is significant disagreement on the correct management. While formal guidelines cannot exist for all situations, this survey highlights the need for consensus on commonly encountered operative scenarios.
