Objective To investigate and analyze the clinical features of children with colorectal polyps and the efficacy of laparoscopic surgery combined with colonoscopy. Methods A total of 98 children with colorectal polyps diagnosed and treated in our hospital from February 2019 to October 2021 were selected as subjects of this study. The clinical characteristics of all children were recorded,and they were divided into the laparoscopic group(laparoscopic surgery combined with colonoscopy,n=40)and the colonoscopy group(colonoscopy,n=58)according to the differences in surgical methods. The therapeutic effect,complication rate,VAS pain score,polyp recurrence and reoperation rate of different surgical methods were compared. Results Among the 98 children,the polyps of 44 cases were in rectum,38 cases in transverse rectum and 16 cases in other sites. The maximum diameter of polyp was(1. 65±0. 24)cm. Polyps were solitary in 83 cases and multiple in 15 cases. The perioperative indexes in the laparoscopic group were significantly improved compared with those in the colonoscopy group(P<0. 05). The incidence of postoperative complications such as infection,bleeding,intestinal perforation and intestinal obstruction was 5. 00% in the laparoscopy group,which was significantly lower than 17. 24% in the colonoscopy group(P<0. 05). The total effective rate of laparoscopic group was 97. 50% one month after operation,which was significantly higher than that of colonoscopy group(82. 76%,P<0. 05). The VAS pain score of the laparoscopic surgery group was significantly lower than that of the colonoscopy group at 1,3 and 7 days after surgery(P<0. 05). After 1 year of follow-up,the combined polyp recurrence rate and reoperation rate were 5. 00% and 2. 50%,which were significantly reduced compared with 18. 97% and 13. 79% in colonoscopy group(P<0. 05). Conclusions The main sites of colorectal polyps in children are rectum and transverse rectum,and most of them are solitary. Laparoscopic and colonoscopic surgery for colorectal polyps in children can promote the recovery of children,improve the overall treatment effect of patients,relieve the pain of children,reduce the occurrence of complications,and reduce the recurrence rate and reoperation rate of follow-up polyps in children.

Objective To explore the prevention and treatment effect of pelvic floor muscle exercise during pregnancy combined with postpartum pelvic floor function rehabilitation therapy on postpartum pelvic floor dysfunction in women. Methods From January 2019 to June 2020, women in our hospital's obstetrics outpatient department for regular obstetric checkups were selected, which ultrasound confirmed it was a singleton full-term delivery. The cases of stillbirth, fetal malformation and placenta previa were excluded. A total of 316 cases met the inclusion criteria and were randomly divided into the observation group and the control group, with 131 cases in the observation group and 185 cases in the control group. Observation group started regular pelvic floor muscle Kegel exercises from 12 weeks of gestation,and accepted pelvic floor rehabilitation therapeutic treatment from 42 days to six weeks postpartum. We summerized the pelvic floor function tests results, pelvic organ prolapse (POP) and stress urinary incontinence (SUI) situation of both groups in 42 days, 3 months and 6 months postpartum. Results The general information of the observation group and the control group showed that there were no statistical differences in age, gestational age of delivery and average weight of newborn (P>0.05). The pelvic floor function 42 days after delivery of the two groups was tested and compared, duration of vaginal contraction and class Ⅱ muscle fiber strength of the observation group [(85.24±22.19) cmH₂O] was significantly higher than that of the control group [(74.14±19.94) cmH₂O], and the difference was statistically significant (P＜0.05). Class I muscle fiber strength, duration of vaginal contraction and class Ⅱ muscle fiber strength were observed at 3 months postpartum, those of observation group[(76.41±16.42) cmH₂O; (4.35±1.78) s; (94.15±18.25) cmH₂O] were significantly higher than that in the control group [(62.45± 17.55) cmH₂O; (3.89±1.52) s; (88.55±18.36) cmH₂O], and the difference were statistically significant (P<0.05). At 6 months postpartum, class I muscle fiber strength, vaginal contraction duration and class Ⅱ muscle fiber strength in observation group [(79.56±15.78) cmH₂O; (5.46±2.01) s; (99.78±23.47) cmH₂O] were significantly higher than that of the control group [(67.63±14.45) cmH₂O; (4.13± 1.45) s; (90.16±18.75) cmH₂O], and the difference were statistically significant (P<0.05). Comparison of the incidence of POP and SUI between the two groups showed that the incidence of SUI in the observation group at 42 days postpartum (28.24%) was significantly lower than that in the control group (35.14%), the difference was statistically significant (P＜0.05). The incidences of POP and SUI in the observation group at 3 months postpartum (18.32%; 13.74%) were significantly lower than that of the control group (22.70%; 17.83%), the difference were statistically significant (P＜0.05). The incidences of POP and SUI in the observation group at 6 months postpartum (0.00%; 0.07%) were significantly lower than that of the control group (8.10%; 11.89%), the difference were statistically significant (P＜0.05). Conclusion Pelvic floor muscle exercise during pregnancy combined with postpartum pelvic floor function rehabilitation therapy can significantly improve postpartum pelvic floor function and significantly reduce the incidence of postpartum pelvic floor dysfunction diseases.

Objective To explore the clinical value of resection of small gastrointestinal stromal tumor(GIST) with transparent cap assisted band ligation. Methods The clinical data of 151 patients who underwent ligation of small GIST assisted with transparent cap in our hospital from February 2017 to February 2020 were retrospectively analyzed, and the complete resection rate, recurrence rate, and complication rate, operation time, hospitalization days and other indicators were analyzed. Results Among the 151 patients with small GIST, 91 cases were located in the fundus of the stomach, 53 cases were in the stomach body, and 7 cases were in the antrum of the stomach. All the lesions were completely resected with the aid of transparent cap. Among lesions of 150 cases, the envelopes were intact and no residue was seen by naked eyes and pathology examination, and 1 case was completely resected after 2 ligations. There were 3 cases of active bleeding, no delayed bleeding, and 105 cases of iatrogenic perforation during the operation. The maximum diameter of the perforation was about 1 cm. There were 3 cases of pneumothorax and mediastinal emphysema, 3 cases of localized peritonitis, and 4 cases of fever. After hemostasis, repair and symptomatic treatment under endoscopy, no case was transferred to surgical departmat during or after operation; the average operation time was (28.3±7.6) minutes, and the average hospital stay was (4.3±1.9) days. Pathological results showed there were 132 cases of very low-risk gastrointestinal stromal tumors and 19 cases of low-risk gastrointestinal stromal tumors. There was no sign of recurrence in the gastroscope during the follow-up. Conclusion The transparent cap assisted ligation resection of small GIST was simple, safe and effective, and had the value of clinical promotion.

目的 评估基于NRS2002系统的多学科营养支持对直肠癌放化疗患者的作用。方法 选取2017年2月—2020年2月我院收治的96例直肠癌放化疗患者作为研究对象,根据入院建档顺序不同分2组,每组48例,对照组接受常规护理,观察组接受基于NRS2002系统的多学科营养支持。比较2组干预前后主观全面评定法(PG-SGA)评分、营养指标[前白蛋白(prealbumin, PA)、血清白蛋白(serum albumin, SA)、转铁蛋白(transferrin, TF)]、癌因性疲乏、生存质量(FLIC评分)。结果 干预后观察组营养状况优于对照组(P＜0.05);干预后观察组SA、PA、TF高于对照组(P＜0.05);干预后观察组癌因性疲乏低于对照组(P＜0.05);干预后观察组生存质量FLIC各维度评分高于对照组(P＜0.05)。结论 基于NRS2002系统的多学科营养支持有助于改善直肠癌放化疗患者营养状态,减轻癌因性疲乏,提升生存质量水平。

Objective To evaluate the efficacy of multidisciplinary nutritional support through NRS2002 system on patients undergoing radiotherapy and chemotherapy with rectal cancer. Methods From February 2017 to February 2020, 96 cases of rectal cancer patients undergoing radiotherapy and chemotherapy in our hospital were selected as the research objects, which were divided into two groups according to the order of filing, 48 cases in each group. The control group received routine nursing, and the observation group received multidisciplinary nutritional support through NRS2002 system. The PG-SGA score, nutritional indexes [prealbumin (PA), serum albumin (SA), transferrin (TF)], cancer-related fatigue and quality of life (FLIC score) were compared between two groups before and after intervention. Results After the intervention, the nutritional status of the observation group was better than that of the control group (P<0.05). The SA, PA, TF of the observation group were higher than those of the control group (P<0.05). The cancer-related fatigue of the observation group was lower than that of the control group (P<0.05), and the FLIC score of the observation group was higher than that of the control group (P<0.05). Conclusion Multidisciplinary nutritional support through NRS2002 system was helpful to improve nutritional status of patients, reduce cancer-related fatigue and improve quality of life of patients with rectal cancer undergoing radiotherapy and chemotherapy.
