Comparative study of laparoscopic Keyhole and Sugarbaker technique in the treatment of terminal paracolostomy hernia / 中华外科杂志

Objective: To compare laparoscopic Keyhole repair with Sugarbaker repair in consecutive patients with parastomal hernia. Methods: From January 2015 to December 2021, 117 patients with parastomal hernia were treated with Keyhole or Sugarbaker laparoscopy repairs in the Department of Hernia and Bariatrci Surgery, the First Affiliated Hospital of University of Science and Technology of China, and the clinical data were retrospectively analyzed. There were 45 males and 72 females, aged (68.6±8.6) years (range: 44 to 84 years). Laparoscopic Sugarbaker repair was performed in 89 cases, and Keyhole repair was performed in 28 cases. The t-test, Mann-Whitney U test, χ2 test and Fisher exact test were used to compare the observation indicators between the two groups, such as operation time, incidence of operation-related complications, and postoperative recurrence rate. Results: The follow-up period was (M(IQR)) 33 (36) months (range: 12 to 84 months). Compared to the Sugarbaker group, the hernia ring area of the Keyhole group was bigger (35 (26) cm2 vs. 25 (16) cm2, Z=1.974, P=0.048), length of stay was longer ((22.0±8.0) d vs. (14.1±6.2) d, t=5.485, P<0.01), and the postoperative rate of recurrence was higher (28.6% (8/28) vs. 6.7% (6/89), χ2=7.675, P=0.006). There was no difference in operation time and postoperative complications between the two groups. Conclusions: Laparoscopic Sugarbaker repair is superior to Keyhole repair in the recurrence rate of parastomal hernia treated with compsite mesh (not funnel-shaped mesh). There are no differences in operation time and postoperative complications between the two groups.

Classification and diagnostic prediction of colorectal cancer using protein profiling of serum and bioinformatics / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To develop a bioinformatic tool and to use it to identify proteomic patterns in serum, distinguishing colorectal cancer from colorectal adenoma and healthy individuals.</p><p><b>METHODS</b>182 serum samples including 55 colorectal cancer patients, 35 colorectal adenoma and 92 healthy individuals were subjected to analysis by surface-enhanced laser desorption/ionization (SELDI) mass spectrometry.</p><p><b>RESULT</b>The diagnostic pattern combined of 4 candidate biomarkers (M/Z 5911, 8922, 8 944, and 8817) could separate colorectal patients from healthy control with a specificity of 93.3%, sensitivity of 90.9%, and Youden index value of 0.84242. The diagnostic pattern combined of 7 candidate biomarkers (M/Z 17247, 18420 ,5911, 9294, 4654, 21694, and 21742) could separate colorectal cancer patients from colorectal adenoma patients with a specificity of 83.2%, sensitivity of 89.3%, and Youden index value of 0.72484.</p><p><b>CONCLUSION</b>Combination of SELDI with bioinformatics tool can identify some new biomarkers from the sera of colorectal cancer patients, which has a high sensitivity and specificity to distinguish colorectal cancer patients from healthy control.</p>
