OBJECTIVE: This study was performed to demonstrate the clinical application of duodenum-preserving pancreatic head resection (DPPHR) as a surgical treatment for pancreatic neuroendocrine tumors (PNETs) in terms of both curability and maintenance of postoperative quality of life. METHODS: Seven patients diagnosed with PNETs underwent DPPHR from January 2011 to December 2021 at our institution. We investigated the clinical relevance of DPPHR based on the patients' clinicopathological findings. RESULTS: The median operative time was 492 min, and the median blood loss was 302 g. Postoperative complications were evaluated according to the Clavien-Dindo classification, and postoperative intra-abdominal bleeding was observed in one patient. Pathological examination revealed a World Health Organization classification of G1 in six patients and G2 in one patient. Microvascular invasion was observed in two patients (29%); however, no patients developed lymph node metastasis or recurrence during the follow-up period. A daughter lesion was observed near the primary tumor in one patient. All patients achieved curative resection, and no tumor specimens showed positive margins. CONCLUSIONS: DPPHR facilitates anatomical resection of the pancreatic head in patients with PNETs as well as detailed pathological evaluation of the resected specimen. Therefore, this surgical procedure is an acceptable alternative to pancreaticoduodenectomy or enucleation for patients with PNETs.

PURPOSE: To identify the problems trainees face during surgical training in Japan. METHODS: A nationwide online questionnaire survey was conducted targeting newly certified surgical trainees. RESULTS: The response rate was 53.8% (758/1410). Among those respondents, 25.6% were women, 71.4% were either married or had a partner, 41.3% had children, 72.7% had performed over 200 surgeries under general anesthesia, and 54.1% had chosen, before graduating from medical school, to become a surgeon. While 88.8% were interested in learning surgical techniques, 63.8% were hesitant to become a surgeon for fear of a compromised quality of private life (QOL). Conversely, only 1.4% chose their surgical training programs based on QOL. Overall, 84.6% of the trainees were satisfied with their training and this correlated with the number of surgeries performed. Only 29.9% received non-technical skill training. The average number of night shifts per month was 5.6, and 10.6% worked over 80 h per week. Harassment was reported by 41.5% of the respondents. Moreover, 33.0% had considered dropping out at some time, primarily because of their QOL (51.1%) or the harassment they had encountered (50.4%). CONCLUSION: This survey revealed that while trainees were satisfied with the overall training system, issues such as long working hours and harassment are prevalent. Working to improve these issues could make surgery more attractive for young trainees.
