The patients were divided into Not Reinforced Group (<jats:italic>n<\/jats:italic>\u2009=\u2009205) and Reinforced Group (<jats:italic>n<\/jats:italic>\u2009=\u2009407) according to the surgical approach to the duodenal stump. The reinforced group was further divided into a modified Q-type purse-string suture embedding method group (QM, <jats:italic>n<\/jats:italic>\u2009=\u2009232) and a conventional suture duodenal stump embedding method group (CM,\u00a0<jats:italic>n<\/jats:italic>\u2009=\u2009175) according to the methods of duodenal stump enhancement.

Additionally, the Not Reinforced Group exhibited a higher rate of Reoperation due to DSL compared to the Reinforced Group [2 (1.0%) vs. 0, <jats:italic>p<\/jats:italic>\u2009=\u20090.046], with one patient in the Not Reinforced Group experiencing mortality due to DSL [1 (0.5%) vs 0, <jats:italic>p<\/jats:italic>\u2009=\u20090.158]. Subgroup analysis within the Reinforced Group revealed that the modified Q-type purse-string suture embedding group (QM) subgroup demonstrated statistically significant advantages over the conventional suture embedding group (CM) subgroup. QM exhibited shorter purse-string closure times (4.11\u2009\u00b1\u20091.840 vs. 6.05\u2009\u00b1\u20091.577, <jats:italic>p<\/jats:italic>\u2009=\u20090.001), higher purse-string closure success rates (93.1% vs. 77.7%, <jats:italic>p<\/jats:italic>\u2009=\u20090.001), and greater satisfaction with purse-string closure [224 (96.6%) vs 157 (89.7%), <jats:italic>p<\/jats:italic>\u2009=\u20090.005]. No occurrences of duodenal stump leakage were observed in the QM subgroup, while the CM subgroup experienced two cases [2 (1.1%)], though the difference was not statistically significant. Both groups did not exhibit statistically significant differences in secondary surgery or mortality related to duodenal stump leakage.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Duodenal Stump Leakage (DSL) is a severe but low-incidence complication. There is no statistically significant relationship between the reinforcement of the duodenal stump and the incidence of DSL. However, laparoscopic reinforcement of the duodenal stump can reduce the severity of fistulas and the probability of Reoperation. The laparoscopic Q-type purse-string suture duodenal stump embedding method is a simple and effective technique that can, to some extent, shorten the operation time and enhance satisfaction with purse-string closure. There is a trend towards reducing the incidence of DSL, thereby improving patient prognosis to a certain extent.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12893-024-02423-1","type":"journal-article","created":{"date-parts":[[2024,4,24]],"date-time":"2024-04-24T08:01:57Z","timestamp":1713945717000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Modified Q-type purse-string suture duodenal stump embedding method for laparoscopic gastrectomy for gastric cancer"],"prefix":"10.1186","volume":"24","author":[{"given":"Longhe","family":"Sun","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiajie","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lili","family":"Ji","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuai","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yayan","family":"Fu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruiqi","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunhua","family":"Qian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiannan","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daorong","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,4,24]]},"reference":[{"key":"2423_CR1","doi-asserted-by":"publisher","first-page":"453","DOI":"10.1056\/NEJMoa0707035","volume":"359","author":"M Sasako","year":"2008","unstructured":"Sasako M, et al.
