Clinical observation of extraction-site incisional hernia after laparoscopic colorectal surgery

BACKGROUND Laparoscopic colorectal cancer surgery increases the risk of incisional hernia(IH)at the tumor extraction site.AIM To investigate the incidence of IH at extraction sites following laparoscopic colo-rectal cancer surgery and identify the risk factors for IH incidence.METHODS This study retrospectively analyzed the data of 1614 patients who underwent la-paroscopic radical colorectal cancer surgery with tumor extraction through the abdominal wall at our center between January 2017 and December 2022.Diffe-rences in the incidence of postoperative IH at different extraction sites and the risk factors for IH incidence were investigated.RESULTS Among the 1614 patients who underwent laparoscopic radical colorectal cancer surgery,303(18.8%),923(57.2%),171(10.6%),and 217(13.4%)tumors were ex-tracted through supraumbilical midline,infraumbilical midline,umbilical,and off-midline incisions.Of these,52 patients developed IH in the abdominal wall,with an incidence of 3.2%.The incidence of postoperative IH was significantly higher in the off-midline incision group(8.8%)than in the middle incision groups[the supraumbilical midline(2.6%),infraumbilical midline(2.2%),and umbilical incision(2.9%)groups](χ^(2)=24.985;P<0.05).Univariate analysis showed that IH occurrence was associated with age,obesity,sex,chronic cough,incision infection,and combined diabetes,anemia,and hypopro-teinemia(P<0.05).Similarly,multivariate analysis showed that off-midline incision,age,sex(female),obesity,incision infection,combined chronic cough,and hypoproteinemia were independent risk factors for IH at the site of laparoscopic colorectal cancer surgery(P<0.05).CONCLUSION The incidence of postoperative IH differs between extraction sites for laparoscopic colorectal cancer surgery.The infraumbilical midline incision is associated with a lower hernia rate and is thus a suitable tumor extraction site.

Micro-power negative pressure wound technique reduces risk of incision infection following loop ileostomy closure

BACKGROUND Prophylactic loop ileostomy is an effective way to reduce the clinical severity of anastomotic leakage following radical resection of rectal cancer.Incisional surgical site infection(SSI)is a common complication after ileostomy closure.AIM To evaluate the efficacy and safety of the micro-power negative pressure wound technique(MPNPWT)in preventing incisional SSI.METHODS This was a prospective,randomized controlled clinical trial conducted at a single center.A total of 101 consecutive patients who underwent ileostomy closure after rectal cancer surgery with a prophylactic ileostomy were enrolled from January 2019 to December 2021.Patients were randomly allocated into an MPNPWT group and a control group.The MPNPWT group underwent intermittent suturing of the surgical incision with 2-0 Prolene and was covered with a micro-power negative pressure dressing.The surgical outcomes were compared between the MPNPWT(n=50)and control(n=51)groups.Risk factors for incisional SSI were identified using logistic regression.RESULTS There were no differences in baseline characteristics between the MPNPWT(n=50)and control groups(n=51).The incisional SSI rate was significantly higher in the control group than in the MPNPWT group(15.7%vs 2.0%,P=0.031).However,MPNPWT did not affect other surgical outcomes,including intra-abdominal complications,operative time,and blood loss.Postoperative hospital stay length and hospitalization costs did not differ significantly between the two groups(P=0.069 and 0.843,respectively).None of the patients experienced adverse effects of MPNPWT,including skin allergy,dermatitis,and pain.MPNPWT also helped heal the infected incision.Our study indicated that MPNPWT was an independent protective factor[odds ratio(OR)=0.005,P=0.025)]and diabetes was a risk factor(OR=26.575,P=0.029)for incisional SSI.CONCLUSION MPNPWT is an effective and safe way to prevent incisional SSI after loop ileostomy closure.

Risk factors and care of early surgical site infection after primary posterior lumbar interbody fusion

Objectives:To explore the risk factors and nursing measures of early surgical site infection(SSI)after posterior lumbar interbody fusion(PLIF).Methods:A total of 468 patients who received PLIF in our hospital from January 2017 to June 2020 were enrolled into this study.According to the occurrence of early SSI,the patients were divided into two groups,and the general data were analyzed by univariate analysis.Multivariate logistic regression analysis was conducted with the dichotomous variable of whether early SSI occurred and other factors as independent variables to identify the risk factors of early SSI and put forward targeted prevention and nursing measures.Results:Among 468 patients with PLIF,18 patients developed early SSI(3.85%).The proportion of female,age,diabetes mellitus and urinary tract infection(UTI),operation segment,operation time,post-operative drainage volume,and drainage time were significantly higher than those in the uninfected group,with statistical significance(P<0.05),whereas the preoperative albumin and hemoglobin in the infected group were significantly lower than those in the uninfected group,with statistical significance(P<0.05).There was no significant difference between the two groups in the American Society of Anesthesiologists(ASA)grading,body mass index(BMI),complications including cardiovascular and cerebrovascular diseases or hypertension(P>0.05).Logistic regression analysis showed that preoperative diabetes mellitus(OR=2.109,P=0.012)/UTI(OR=1.526,P=0.035),prolonged drainage time(OR=1.639,P=0.029)were risk factors for early SSI.Men(OR=0.736,P=0.027)and albumin level(OR=0.526,P=0.004)were protective factors in reducing early SSI.Conclusions:Women,preoperative diabetes/UTI,hypoproteinemia,and prolonged drainage time are risk factors for early SSI after PLIF.Clinical effective preventive measures should be taken in combination with targeted nursing intervention to reduce the risk of early SSI.

Analysis of the Role of Nursing Intervention in Operating Room in the Prevention of Incision Infection in Orthopedic Aseptic Surgery

Objective:To explore and analyze the role of nursing in the operating room in the prevention of incision infection in aseptic orthopedic surgery.Methods:68 patients that underwent aseptic orthopedic surgery in our hospital from January 2021 to December 2022.They were divided into a research group(n=34)and a control group(n=34)by the random number table method.The patients in the control group received conventional nursing intervention in the operating room,and the patients in the study group received the optimized and modified nursing intervention in the operating room;then,the related indicators of nursing intervention of the two groups were compared.Results:The incidence of incision infection in the study group was lower than that of the control group(P<0.05);the average duration of surgery and length of stay the study group were lower than those in the control group(P<0.05);the stress response indexes of patients in the study group were lower than those in the control group 24 hours after operation(P<0.05);the degree of satisfaction of the patients in the study group to the services provided by the nursing staff was significantly higher than that of the control group(P<0.05).Conclusion:High-quality nursing intervention in the operating room for aseptic orthopedic surgery patients can significantly reduce the incidence of incision infection,reduce the stress response caused by surgery,shorten the duration of surgery and length of stay,and improve nursing satisfaction,which makes it worthy of popularization.

Incidence and risk factors for incisional surgical site infection in patients with Crohn’s disease undergoing bowel resection

Background:Patients with Crohn’s disease(CD)are often reported to be at a high risk for incisional surgical site infection(SSI).The aim of this study was to identify the risk factors associated with post-operative incisional SSI in CD patients after bowel resection.Method:CD patients undergoing bowel resection between 2007 and 2015 were enrolled.Demographic and clinical features related to post-operative incisional SSI were analysed using both univariate and multivariate logistical analyses.Results:Of all eligible patients(n=159),123(77.4%)were male,with a mean age at surgery of 33.4611.8 years.A total of 35(22.0%)CD patients developed post-operative incisional SSI.Post-operative incisional SSI was more likely to happen in patients who had penetrating type of disease(P=0.018),underwent bowel resection for the indication of chronic fistula(P=0.005)and had an intra-operative finding of fistula(P=0.001).A greater proportion of patients with post-operative incisional SSI were found to have anemia(P=0.019)but elevated levels of white blood cells(P=0.027),neutrophils(P=0.006)as well as an elevated percentage of neutrophils(P=0.005).Multivariate logistic regression analysis showed that anemia(odds ratio[OR]:3.31,95%confidence interval[CI]:1.05-10.46,P=0.041),an elevated percentage of neutrophils(OR:2.85,95%CI:1.23-6.59,P=0.014)and an intra-operative finding of fistula(OR:3.76,95%CI:1.53-9.21,P=0.004)were significantly associated with the risk for post-operative incisional SSI.Conclusions:Anemia,elevated percentage of neutrophils and intra-operative finding of fistula are predictors for the development of post-operative incisional SSI in CD patients undergoing bowel resection.Favorable pre-operative nutrition status and low inflammatory status may lessen the incidence of post-operative incisional SSI.
