Modified Q-type purse-string suture duodenal stump embedding method for laparoscopic gastrectomy for gastric cancer

Table 4 Perioperative-related indicators between the QM group and CM group

Perioperative-related indicators	QM (n = 232)	CM (n = 175)	Volume	p
Operative time for Total gastrectomy, min, median(range), min	128(103 ~ 158)	131(104 ~ 165)	z = -0.655	0.547
Operative time for Distal gastrectomy, min, median(range)	186(160 ~ 203)	190(168 ~ 210)	z = -1.212	0.203
Duodenal stump reinforcement time, min	4.11 ± 1.840	6.05 ± 1.577	t = -11.225	0.001*
Initial success rate of burying the duodenal stump, n	216(93.1%)	136(77.7%)	χ² = 20.214	0.001*
Satisfaction rate of purse string suture, n	224(96.6%)	157(89.7%)	χ² = 7.798	0.005*
Duodenal stump leakage, n	0	2(1.1%)	χ² = 2.665	0.103
Reoperation for duodenal stump leakage, n	0	0	-	-
Reoperation for duodenal stump leakage-related death, n	0	0	-	-

Initial success rate of burying the duodenal stump: This metric is determined by retrospectively reviewing the surgical video footage of each enrolled patient, observing the process of burying the duodenal stump. It involves counting the number of cases where complete burying was achieved during the first suturing
Satisfaction rate of purse string suture: This assessment is performed using the Satisfaction scale for laparoscopic duodenal stump suturing, developed through comprehensive evaluation at our center (scale displayed in Fig. 4)
