Is There an Improvement of Antibiotic Use in China？ Evidence from the Usage Analysis of Combination Antibiotic Therapy for Type Ⅰ Incisions in 244 Hospitals

The improvement of antibiotic rational use in China was studied by usage analysis of combination antibiotic therapy for type Ⅰ incisions in 244 hospitals. Five kinds of hospitals, including general hospital, maternity hospital, children＇s hospital, stomatological hospital and cancer hospital, from 30 provinces were surveyed. A systematic random sampling strategy was employed to select outpatient prescriptions and inpatient cases in 2011 and 2012. A total of 29 280 outpatient prescriptions and 73 200 inpatient cases from 244 hospitals in each year were analyzed. Data were collected with regards to the implementation of the national antibiotic stewardship program（NASP）, the overall usage and the prophylactic use of antibiotic for type Ⅰ incisions. Univariate analysis was used for microbiological diagnosis rate before antimicrobial therapy, prophylactic use of antibiotics for typeⅠincision operation, and so on. For multivariate analysis, the use of antibiotics was dichotomized according to the guidelines, and entered as binary values into logistic regression analysis. The results were compared with the corresponding criteria given by the guidelines of this campaign. The antibiotic stewardship in China was effective in that more than 80% of each kind of hospitals achieved the criteria of recommended antibiotics varieties. Hospital type appeared to be a factor statistically associated with stewardship outcome. The prophylactic use of antibiotics on type Ⅰ incision operations decreased by 16.22%（P〈0.05）. The usage of combination antibiotic therapy for type Ⅰ incisions was also decreased. Region and bed size were the main determinants on surgical prophylaxis for type Ⅰ incision. This national analysis of hospitals on antibiotic use and stewardship allows relevant comparisons for bench marking. More efforts addressing the root cause of antibiotics abuse would continue to improve the rational use of antibiotics in China.

Effect of femtosecond laser-assisted steepest-meridian clear corneal incisions on preexisting corneal regular astigmatism at the time of cataract surgery

AIM:To investigate the clinical efficacy and safety of femtosecond laser-assisted steepest-meridian clear corneal incisions for correcting preexisting corneal astigmatism performed at the time of cataract surgery.METHODS:This prospective case series study comprised consecutive age-related cataract patients with corneal regular astigmatism(range:+0.75 to+2.50 D)who had femtosecond laser-assisted steepest-meridian clear corneal incisions(single or paired).Corneal astigmatism was performed with the Pentacam preoperatively and 3 mo postoperatively.Total corneal astigmatism and steepestmeridian measured in the 3-mm central zone were used to guide the location,size and number of clear corneal incision.The vector analysis of astigmatic change was performed using the Alpins method.RESULTS:Totally 138 eyes of 138 patients were included.The mean preoperative corneal astigmatism was 1.31±0.41 D,and was significantly reduced to 0.69±0.34 D(equivalent to difference vector)after surgery(P<0.01).The surgically-induced astigmatism was 1.02±0.54 D.The correction index(ratio of target induced astigmatism and surgically-induced astigmatism:0.72±0.36)as well as the magnitude of error(difference between surgically-induced astigmatism and target induced astigmatism:-0.29±0.51)represented a slight under correction.For angle of error,the arithmetic mean was 1.11±13.70,indicating no significant systematic alignment errors.CONCLUSION:Femtosecond-assisted steepest-meridian clear corneal incision is a fast,customizable,adjustable,precise,and safe technique for the reduction of low to moderate corneal astigmatism during cataract surgery.

Necrotizing fasciitis of cryptoglandular infection treated with multiple incisions and thread-dragging therapy:A case report

BACKGROUND Necrotizing fasciitis is a fulminant necrotizing soft tissue disease with a high fatality rate.It always starts with impact on the deep fascia rapidly and might result in secondary necrosis of the subcutaneous tissue,fascia,and muscle.Thus,timely and multiple surgical operations are needed for the treatment.Meanwhile,the damage of skin and soft tissue caused by multiple surgical operations may require dermatoplasty and other treatments as a consequence.CASE SUMMARY Here,we report a case of 50-year-old male patient who was admitted to our hospital with symptoms of necrotizing fasciitis caused by cryptoglandular infection in the perianal and perineal region.The symptoms of necrotizing fasciitis,also known as the cardinal features,include hyperpyrexia,excruciatingly painful lesions,demonstration gas in the tissue,an obnoxious foul odor and uroschesis.The results of postoperative pathology met the diagnosis.Based on the premise of complete debridement,multiple incisions combined with thread-dragging therapy(a traditional Chinese medicine therapy)and intensive supportive therapies including comprising antibiotics,nutrition and fluids were given.The outcome of the treatment was satisfactory.The patient recovered quickly and achieved ideal anal function and morphology.CONCLUSION Timely and effective debridement and multiple incisions combined with thread-dragging therapy are an integrated treatment for necrotizing fasciitis.

Toric Intraocular Lens vs. Peripheral Corneal Relaxing Incisions to Correct Astigmatism in Eyes Undergoing Cataract Surgery

Purpose:.To compare toric intraocular lens implantation(ToricIOL).with peripheral corneal relaxing incisions(PCRIs) for astigmatism correction in patients undergoing cataract surgery.Methods: 54 patients(54 eyes) with more than 0.75 diopter(D).of preexisting corneal astigmatism were classified as group A(0.75-1.50D) or group B(1.75-2.50D). The patients were randomized to undergo Toric-IOL or PCRIs in the steep axis with spherical IOL implantation..Log MAR uncorrected visual acuity(Log MAR UCVA), Log MAR best corrected vi sual acuity.(Log MAR BCVA),.error of vector(|EV|), surgery induced refraction correction.(|SIRC |),.and correction rates(CR) were measured 1 month and 6 months postoperatively.Results: At 6 months postoperatively, all 54 eyes had LogMAR BCVA≤0.2. Patients who underwent PCRIs and ToricIOL with Log MAR BCVA≤0.1 showed no significant differences in group A(P=1.00) or in group B(P=0.59). Group A showed no significant differences in Log MAR UCVA(P =0.70), |EV|(P=0.13), |SIRC|(P=0.71), and CR(P=0.56)in patients underwent PCRIs and Toric-IOL. However, group B showed significant differences in Log MAR UCVA(P <0.01), |EV|(P<0.01)), |SIRC|(P<0.01), and CR(P<0.01).The Log MAR UCVA and |EV | between 1 and 6 months showed no significant differences in patients in group A. However, in group B, they are significant differences.Conclusion:.The efficacy and stability of Toric-IOL and PCRIs were equal in low astigmatic patients..Toric-IOL achieved an enhanced effect over PCRIs in higher astigmatic patients.PCRIs had the more refractive regression than Toric-IOL in 6months.

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.

Ten-year observation of corneal densitometry and associated factors following small incision lenticule extraction

●AIM:To investigate the long-term changes of corneal densitometry(CD)and its contributing elements after small incision lenticule extraction(SMILE).●METHODS:Totally 31 eyes of 31 patients with mean spherical equivalent of-6.46±1.50 D and mean age 28.23±7.38y were enrolled.Full-scale examinations were conducted on all patients preoperatively and during followup.Visual acuity,manifest refraction,axial length,corneal thickness,corneal higher-order aberrations,and CD were evaluated.●RESULTS:All surgeries were completed successfully without complications or adverse events.Ten-year safety index was 1.17±0.20 and efficacy 1.04±0.28.CD value of 0–6 mm zones in central layer was statistically significantly lower 10y postoperatively,compared with preoperative values(0–2 mmΔ=-1.62,2–6 mmΔ=-1.24,P<0.01).There were no correlations between CD values and factors evaluated.●CONCLUSION:SMILE is a safe and efficient procedure for myopia on a long-term basis.CD values get lower 10y postoperatively,whose mechanism is to be further discussed.

Potential applications of single-incision laparoscopic totally preperitoneal hernioplasty

BACKGROUND The totally preperitoneal(TPP)approach is a new concept that was recently introduced.Although the TPP approach combined with single-incision laparoscopic hernia repair has its own advantages,there is little evidence reflecting the characteristics and feasibility of either approach.AIM To analyze the potential applications of single-incision laparoscopic TPP(SILTPP)inguinal hernia hernioplasty for the treatment of inguinal hernias.METHODS A total of 152 SIL-TPP surgeries were performed at the First Affiliated Hospital of Ningbo University from February 2019 to November 2022.A single-port,named Iconport,and standard laparoscopic instruments were used during the operation.Demographic data,intraoperative parameters and short-term postoperative outcomes were collected and retrospectively analyzed.RESULTS The demographic data of 152 patients underwent SIL-TPP were shown in Table 1.The average age was 49.5 years(range from 21 to 81 years).The average body mass index was 27.7 kg/m^(2)(range from 17.7 kg/m^(2) to 35.6 kg/m^(2)).SIL-TPP were conducted successfully in 147 patients.Three patients were converted to the SILtransabdominal preperitoneal laparoscopic herniorrhaphy at the initial stage of the study due to a lack of experience.In 2 patients with incisional hernias,an auxiliary operation hole was added during the SIL-TPP procedure,as required for surgery.The mean operative time was 64.5 minutes(range:36.0-110.0 minutes)for unilateral direct and femoral hernias and 81.6 minutes for indirect hernias(range:40.0-150.0 minutes).The mean postoperative hospital stay was 3.4 days.CONCLUSION SIL-TPP is feasible and has advantages for inguinal hernia repair.SIL-TPP has potential benefits for patients with various abdominal wall hernias.Consequently,doctors should be encouraged to actively apply the TPP approach combined with a single incision in their daily work.

Changes in posterior corneal elevation after small incision lenticule extraction for different myopic diopters

●AIM:To study the changes and effect factors of posterior corneal surface after small incision lenticule extraction(SMILE)with different myopic diopters.●METHODS:Ninety eyes of 90 patients who underwent SMILE were included in this retrospective study.Patients were allocated into three groups based on the preoperative spherical equivalent(SE):low myopia(SE≥-3.00 D),moderate myopia(-3.00 D>SE>-6.00 D)and high myopia(SE≤-6.00 D).Posterior corneal surfaces were measured by a Scheimpflug camera preoperatively and different postoperative times(1wk,1,3,6mo,and 1y).Posterior mean elevation(PME)at 25 predetermined points of 3 concentric circles(2-,4-,and 6-mm diameter)above the best fit sphere was analyzed.●RESULTS:All surgeries were completed uneventfully and no ectasia was found through the observation.The difference of myopia group was significant at the 2-mm ring at 1 and 3mo postoperatively(1mo:P=0.017;3mo:P=0.018).The effect of time onΔPME was statistically significant(2-mm ring:P=0.001;4-mm ring:P<0.001;6-mm ring:P<0.001).The effect of different corneal locations onΔPME was significant except 1wk postoperatively(1mo:P=0.000;3mo:P=0.000;6mo:P=0.001;1y:P=0.001).Posterior corneal stability was linearly correlated with SE,central corneal thickness,ablation depth,residual bed thickness,percent ablation depth and percent stromal bed thickness.●CONCLUSION:The posterior corneal surface changes dynamically after SMILE.No protrusion is observed on the posterior corneal surface in patients with different degrees of myopia within one year after surgery.SMILE has good stability,accuracy,safety and predictability.

Endoscopic radial incision and cutting method for adult congenital duodenal webs:A case report

BACKGROUND Congenital duodenal webs are rare in adults and can lead to various symptoms such as nausea,vomiting,and postprandial fullness.The treatment for this disease is mostly surgical.Endoscopic treatment techniques have been developed and attempted for this disease.Endoscopic radial incision and cutting(RIC)techniques are reportedly very effective in benign anastomotic stricture.This case report highlights the effectiveness and safety of endoscopic RIC as a minimally invasive treatment for adult congenital duodenal webs.CASE SUMMARY A 23-year-old female patient with indigestion was referred to a tertiary hospital.The patient complained of postprandial fullness in the epigastric region.Previous physical examinations or blood tests indicated no abnormalities.Computed tomography revealed an eccentric broad-based delayed-enhancing mass-like lesion in the second portion of the duodenum.Endoscopy showed an enlarged gastric cavity and a significantly dilated duodenal bulb;a very small hole was observed in the distal part of the second portion,and scope passage was not possible.Gastrografin upper gastrointestinal series was performed,revealing an intraduodenal barium contrast-filled sac with a curvilinear narrow radiolucent rim,a typical"windsock"sign.Endoscopic RIC was performed on the duodenal web.The patient recovered uneventfully.Follow-up endoscopy showed a patent duodenal lumen without any residual stenosis.The patient reported complete resolution of symptoms at the 18-month follow-up.CONCLUSION Endoscopic RIC may be an effective treatment for congenital duodenal webs in adults.

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.

Single incision laparoscopic surgery for hepatocellular carcinoma

Single incision laparoscopic liver resection(SILLR)is the most recent develop-ment in the laparoscopic approach to the liver.SILLR for hepatocellular carci-noma(HCC)has developed much more slowly than multiport LLR.So far,195 patients completed SILLR for HCC.In this paper,we reviewed all published papers about SILLR for HCC and discussed the feasibility of the SILLR,peri and postoperative findings,tricks of patient selection and whether SILLR compromise the oncological principles.

Incisional Negative Pressure Wound Therapy in the Prevention of Surgical Site Infection after Vascular Surgery with Inguinal Incisions: Rationale and Design of a Randomized Controlled Trial (INVIPS-Trial)

Background/Aims: Inguinal incisions are a common route of access in vascular surgery. Due to anatomical challenges and a diverse bacterial flora in this area, surgical site infections (SSI) represent a common, debilitating and sometimes life-threatening complication. The INVIPS-Trial evaluates the role of Negative Pressure Wound Therapy (NPWT) on closed inguinal incisions in elective vascular surgery to prevent SSI and other wound complications. Methods: This randomized controlled trial (RCT) registered at ClinicalTrials.gov (Identifier: NCT01913132) compares the effects of a NPWT dressing (PICO, Smith & Nephew, UK) and the center’s standard wound dressing (Vitri Pad, ViTri Medical, Sweden) on postoperative wound complications, especially SSI. The study includes two distinct vascular procedures with different SSI risk profiles: endovascular aortic repair (EVAR) and open surgical approaches involving the common femoral artery (OPEN). Results: Four hundred ninety-five groin incisions in both treatment arms are anticipated to be included in the EVAR group and 147 inguinal incisions in both treatment arms in the OPEN group. Since a large percentage of inguinal vascular procedures in both groups but especially in the EVAR group are performed bilaterally, many patients can serve as their own control by randomly receiving NPWT on one and the standard dressing on the contralateral inguinal incision. Conclusions: This ongoing RCT attempts to elucidate the potential benefit of NPWT on closed inguinal incisions after different vascular procedures. Outcome and conclusions of this trial could have implications on postoperative wound care of patients in both vascular surgery and other surgical specialties.

Management Measures for Preventing Postoperative Incision Infections in General Surgery at Primary Hospitals

Objective:To analyze the management measures and effects of preventing postoperative incision infections in the general surgery department of primary hospitals.Methods:Forty-nine surgical patients with 11 healthcare workers who were admitted to the general surgery department of the primary hospital between August 2021 and August 2022 were selected as the routine group for routine incision infection management.Forty-nine surgical patients with 11 healthcare workers admitted to the same department between September 2022 and September 2023 were selected as the prevention group for prophylactic management of postoperative incision infections.The incision infection rate,knowledge,attitude,and practice(KAP)scores,and management satisfaction of the patients as well as the management skill scores of healthcare workers were compared between the two groups.Results:The rate of postoperative incision infection in the prevention group was lower than that in the routine group;after implementing management measures,patients in the prevention group had higher KAP scores than those in the routine group;patients in the prevention group were more satisfied with the management than those in the routine group;and healthcare workers in the prevention group had higher scores than those in the routine group,with P<0.05 for the comparison between the groups.Conclusion:The implementation of preventive management for general surgery patients in primary hospitals can reduce the incidence of postoperative incision infection and improve the KAP of patients,with higher management satisfaction.It can also enhance the management skills of healthcare workers,thus improving their overall management level.

Analysis of Ultrasonic Emulsification Surgery and Small Incision Cataract Extracapsular Extraction Surgery for Cataract Clinical Treatment Level Improvement

Objective:To analyze the efficacy of ultrasonic emulsification and small incision cataract extracapsular extraction in cataract patients.Methods:96 cataract patients admitted from May 2021 to May 2023 were selected and randomly grouped into group A(ultrasonic emulsification)and group B(small-incision extracapsular cataract extraction),with 48 cases each.Results:At 1 week,1-month,and 3 months post-operation,the visual acuity of group A was higher and the astigmatism value was lower than that of group B(P<0.05);at 12h,24h,and 48h post-operation,the intraocular pressure of group A was higher than that of group B(P<0.05);the thickness of macular area of group A was lower than that of group B at 1 week and 1-month post-operation(P<0.05).Conclusion:Ultrasonic emulsification in cataract patients was slightly better than small incision cataract extracapsular extraction in correcting astigmatism,improving visual acuity,and regulating macular thickness.However,due to the high energy of ultrasonic emulsification,the risk of complications such as high postoperative intraocular pressure was higher.Small-incision extracapsular cataract extraction has better application value in economically disadvantaged areas.

Single-incision laparoscopic cholecystectomy:Single institution experience and literature review

Single-incision laparoscopic surgery is a rapidly evolving field as a bridge between traditional laparoscopic surgery and natural orifice transluminal endoscopic surgery.We report one of the initial clinical experiences in Japan with this new technique.Four cases of gallbladder diseases were selected for this new technique.A single curved intra-umbilical 25-mm incision was made by pulling out the umbilicus.A 12-mm trocar was placed through an open approach,and the abdominal cavity was explored with a 10-mm semiflexible laparoscope.Two 5-mm ports were inserted laterally from the laparoscope port.A 2-mm mini-loop retractor was inserted to retract the fundus of the gallbladder.Dissection was performed using an electric cautery hook and an Endograsper roticulator.There were two women and two men with a mean age of 50.5 years(range:40-61 years).All procedures were completed successfully without any perioperative complications.In all cases,there was no need to extend the skin incision.Average operative time was 88.8 min.Postoperative follow-up didnot reveal any umbili-cal wound complication.Single-incision laparoscopic cholecystectomy is feasible and a promising alternative method as scarless abdominal surgery for the treatment of some patients with gallbladder disease.

Healing time of incision infection after hepatobiliary surgery treated by needle-free incision suture closure

AIM: To compare the effectiveness of needle-free incision suture closure with butterfly tape and traditional secondary suturing techniques in treating incision infection. METHODS: Two hundred and twenty-three patients with incision infection following hepatobiliary surgery at a tertiary hospital were randomly divided into three groups: 90 patients were closed by needle-free incision suture closure, which gradually closed the incision wound when drainage from incision infection was visibly decreased and healthy granulation tissues had grown; 79 patients were closed by butterfly bandage; another 54 patients were closed by traditional secondary suturing technique. Healing time of incision infection was calculated from the beginning of dressing change to the healing of the incision. RESULTS: Healing time in the needle-free incision suture closure group (24.2 +/- 7.2 d) was significantly shorter than that in the butterfly bandage group (33.3 +/- 11.2 d) and the traditional secondary suturing group (36.2 +/- 15.3 d) (P < 0.05). Healing time in the butterfly bandage group appeared to be slightly shorter than that in the secondary suture group, but the difference was not statistically significant (P > 0.05). CONCLUSION: Needle-free incision suture closure could gradually close the infection wound at the same time of drainage and dressing change, thereby shortening the healing time.

Learning curve of transumbilical suture-suspension single-incision laparoscopic cholecystectomy

AIM: To investigate the learning curve of transumbilical suture-suspension single-incision laparoscopic cholecystectomy (SILC). METHODS: The clinical data of 180 consecutive transumbilical suture-suspension SILCs performed by a team in our department during the period from August 2009 to March 2011 were retrospectively analyzed. Patients were divided into nine groups according to operation dates, and each group included 20 patients operated on consecutively in each time period. The surgical outcome was assessed by comparing operation time, blood loss during operation, and complications between groups in order to evaluate the improvement in technique.RESULTS: A total of 180 SILCs were successfully performed by five doctors. The average operation time was 53.58 ± 30.08 min (range: 20.00-160.00 min) and average blood loss was 12.70 ± 11.60 mL (range: 0.00-100.00 mL). None of the patients were converted to laparotomy or multi-port laparoscopic cholecystectomy. There were no major complications such as hemorrhage or biliary system injury during surgery. Eight postoperative complications occurred mainly in the first three groups (n = 6), and included ecchymosis around the umbilical incision (n = 7) which resolved without special treatment, and one case of delayed bile leakage in group 8, which was treated by ultrasound-guided puncture and drainage. There were no differences in intraoperative blood loss, postoperative complications and length of postoperative hospital stay among the groups. Bonferroni's test showed that the operation time in group 1 was significantly longer than that in the other groups (F = 7.257, P = 0.000). The majority of patients in each group were discharged within 2 d, with an average postoperative hospital stay of 1.9 ± 1.2 d. CONCLUSION: Following scientific principles and standard procedures, a team experienced in multi-port laparoscopic cholecystectomy can master the technique of SILC after 20 cases.
