This study aimed to compare complication rates between pylorus-preserving gastrectomy (PPG) and distal gastrectomy (DG) using Korean nationwide survey data and propensity score weighting (PSW). PPG preserves gastric function but may lead to more postoperative complications than DG. Methods and Results. We analyzed 9424 gastric cancer patients who underwent either DG (n = 9183) or PPG (n = 241). PSW balanced variables such as age, sex, TNM stage, comorbidities, ASA score, and surgical approach. Before PSW, 87.8% of DG patients and 87.1% of PPG patients had no complications (p = 0.053). Severe complications (Clavien\u2013Dindo IIIa or higher) were more frequent in PPG (6.6%) than in DG (3.8%) (p = 0.039). After PSW, overall complication rates (p = 0.960) and severe complication rates (p = 0.574) were similar between groups. Incidence rates of anastomotic stricture and leakage were higher in PPG (2.9% and 1.7%) compared to DG (0.6% and 0.5%) (p = 0.001 and 0.036) before PSW, but these differences were not significant after PSW (p = 0.999 and 0.123). Conclusion. The PSW-adjusted analysis indicates no significant difference in overall and severe complication rates between PPG and DG in gastric cancer patients.<\/jats:p>","DOI":"10.3390\/cancers16122203","type":"journal-article","created":{"date-parts":[[2024,6,12]],"date-time":"2024-06-12T06:47:30Z","timestamp":1718174850000},"page":"2203","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Comparative Study of Postoperative Complications Associated with Distal Gastrectomy and Pylorus-Preserving Gastrectomy among Gastric Cancer Patients Based on Nationwide Survey Data and Propensity Score Weighting"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9061-6236","authenticated-orcid":false,"given":"Sang-Ho","family":"Jeong","sequence":"first","affiliation":[{"name":"Department of Surgery, Gyeongsang National University College of Medicine, Gyeongsang National University Changwon Hospital, Changwon 51472, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miyeong","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Gyeongsang National University Changwon Hospital, Changwon 51472, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5771-3832","authenticated-orcid":false,"given":"Kyung","family":"Seo","sequence":"additional","affiliation":[{"name":"Department of Surgery, Kosin University Gospel Hospital, Busan 49267, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5868-0465","authenticated-orcid":false,"given":"Rock","family":"Kim","sequence":"additional","affiliation":[{"name":"Regional Cardiocerebrovascular Disease Center, Gyeongsang National University Hospital, Jinju 52727, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5798-4595","authenticated-orcid":false,"given":"Jae-Seok","family":"Min","sequence":"additional","affiliation":[{"name":"Department of Surgery, Korea University College of Medicine, and Division of Foregut Surgery, Korea University Anam Hospital, Seoul 02841, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Information Committee of the Korean Gastric Cancer Association","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1079","DOI":"10.1097\/SLA.0000000000001565","article-title":"A Randomized Controlled Trial of Vagus Nerve-preserving Distal Gastrectomy versus Conventional Distal Gastrectomy for Postoperative Quality of Life in Early Stage Gastric Cancer Patients","volume":"263","author":"Kim","year":"2016","journal-title":"Ann.
