  • Preliminary application of negative pressure suction cup in young children with pectus excavatum

    Objective To summarize and analyze the clinical efficacy of negative pressure suction cup in the treatment of young children (≤ 6 years old) with pectus excavatum. Methods The relevant clinical medical records of the children with pectus excavatum who received negative pressure suction cup treatment in our hospital outpatient department from May 2019 to January 2023 were collected. The age, sex, type, severity, depth of depression, duration of use and prognosis of children with pectus excavatum were retrospectively analyzed. Results Finally 100 children were treated with negative pressure suction cups according to the doctor’s advice for at least 3 months. The 99 patients was effective, the effective rate was 99%, the excellent and good rate was 52.00%, and the complication rate was 8.00%, After treatment, the Haller index and the depth of sternal depression were reduced compared with those before treatment (P<0.001), and there was no statistical difference in the effective rate and excellent rate between different genders, different ages, different types of pectus excavatum, or different severity (P>0.05). Conclusion Negative pressure suction cup is safe and effective in the treatment of youngchildren (≤ 6 years old) with pectus excavatum, and the correction effect has nothing to do with gender, type and severity .

  • Real-time intraoperative anatomy study of superior mesenteric vessels and its tributaries:A single-center prospective cohort study of 200 cases

    ObjectiveTo explore the prevalence and adjacency of the tributaries of superior mesenteric vessel. MethodsThis study is a prospective study. The patients with right-sided colonic malignant tumor who underwent laparoscopic complete mesocolon excision at the Division of Colorectal Surgery of Peking Union Medical College Hospital from July 2016 to September 2022 were collected. The real-time observation and evaluation of vascular anatomy was performed by the operator and recorded by a resident. The continuous variables without a normal distribution were summarized as median (P25, P75). The categorical variables were presented as number (%). ResultsA total of 200 patients were enrolled, including 114 males and 86 females, with a median age of 63.5 (53.5, 72.0) years. The prevalence of ileocolic artery and vein was 98.0% (196/200) and 98.5% (197/200), respectively. There were 168 (86.2%) cases of the ileocolic vein accompanied the course of the ileocolic artery at the origin in 195 patients with simultaneous presence of ileocolic artery and vein. The right colic artery and vein was present in 39.5% (79/200) and 18.5% (37/200) patients, respectively. The prevalence of the middle colic artery and vein was 96.5% (193/200) and 90.5% (181/200), respectively. And the prevalence of the middle colic vein accompanied the path of the middle colic artery at the root was 67.8% (118/174) in the 174 patients with simultaneous presence of middle colic artery and vein. The trunk length of the middle colic artery was 2.2 (1.6, 3.2) cm. The Henle trunk was present in 185 (92.5%) cases, with a trunk length of 1.00 (0.50, 1.40) cm, and its lower edge was 2.80 (2.20, 3.30) cm from the junction of the pancreatic head and the horizontal part of the duodenum. ConclusionsThe results from the data analysis of this study suggest that the ileocolic artery and vein are present most constantly with a high incidence of the ileocolic vein accompanied the course of the ileocolic artery at the origin of superior mesenteric vessels. Therefore ileocolic artery and vein are expected to serve as an optimal anatomical landmarks for the caudal-to-cranial medial approach in laparoscopic complete mesocolon excision.
