RESUMEN
Objective:To explore and analyze the reliability and safety of sham feeding in facilitating the recovery of gastrointestinal function after laparoscopic appendectomy (LA), by using a new device, the Artificial Intelligence Bowel Tone Monitoring System.Methods:The data of 100 cases in Shaanxi Provincial People′s Hospital from Dec. 2020 to Sep. 2022 with acute appendicitis operated by LA who met the inclusion criteria. In this prospective study, participants were divided by random number table into a control group and an experimental group, with 50 cases in each group. The control group performed routine postoperative LA care, and the experimental group performed routine postoperative LA care and sham-feeding state care. The age, gender, recovery time of postoperative bowel sounds, time of first postoperative anal discharge, postoperative nausea and vomiting, abdominal distention, dry mouth and halitosis, and postoperative abdominal pain and other complications were recorded. GraphPad Prism 9.0 and SPSS 22.0 software were adopted to conduct data organization and analysis.Results:There were 100 valid cases in this trial. There were no statistical differences between the two groups in terms of gender, age, duration of surgery, abdominal pain and other symptoms ( P>0.05). The recovery time of bowel sounds after surgery was (8.92±0.56) h in the experimental group and (10.55±0.88) h in the control group, which was statistically significant ( t=10.99, P<0.0001); the recovery time of bowel sounds after surgery was (20.10±0.50) h in the experimental group and (20.96±0.59) h in the control group. There was a statistically significant difference between the two groups ( t=7.84, P<0.0001); there was a statistically significant difference between the experimental group (22%) and the control group (42%) for postoperative nausea and vomiting ( χ2=4.60, P=0.032); there was a statistically significant difference between the experimental group (16%) and the control group (52%) for postoperative abdominal distension ( χ2= There was a statistical difference between the experimental group (40%) and the control group (68%) ( χ2=7.89, P=0.005). The number of hospitalization days in the control group was (11.40±2.47) days and the days in the experimental group was (9.30±2.01) d, the difference between the two groups was statistically significant ( t=4.65, P<0.001); the hospitalization cost in the control group was (27 270.11±2 645.30) yuan and the cost in the experimental group was (23 669.68±2 841.28) yuan, the difference between the two groups was statistically significant ( t=6.56, P<0.001). Conclusion:To a certain extent, sham feeding can accelerate the recovery of gastrointestinal function in patients after LA, reduce the common postoperative discomfort, length of stay and hospital costs of patients.
RESUMEN
PURPOSE: We aimed to examine the effect of gum chewing after laparoscopic colorectal cancer surgery. METHODS: We reviewed the medical records of patients who underwent laparoscopic colorectal cancer surgery in Incheon St. Mary's Hospital, The Catholic University of Korea School of Medicine. We divided the patients into 2 groups: group A consisted of 67 patients who did not chew gum; group B consisted of 65 patients who chewed gum. We analyzed the short-term clinical outcomes between the two groups to evaluate the effect of gum chewing. RESULTS: The first passage of gas was slightly earlier in group B, but the difference was not significant. However, the length of hospital stay was 6.7 days in group B, which was significantly shorter than that in group A (7.3 days, P = 0.018). CONCLUSION: This study showed that length of postoperative hospital stay was shorter in the gum-chewing group. In future studies, we expect to elucidate the effect of gum chewing on the postoperative recovery more clearly.
