Evaluation of the safety and quality of day-case cataract surgery based on 4151 cases

AIM: To evaluate the safety, quality and prospects of day-case cataract surgery performed in a Jiangsu public tertiary hospital METHODS: The general and clinical data for patients who underwent day-case cataract surgery between August 1, 2014 and December 31, 2016 at this hospital were collected. The incidences of intraoperative and postoperative complications, preoperative and postoperative bestcorrected visual acuities(BCVAs), delayed discharge rate, rate of unplanned re-admission to hospital, and patient satisfaction were analyzed. RESULTS: A total of 4151 patients received cataract phacoemulsification surgery to correct age-related, congenital, traumatic, or complicated cataracts. Of these, age-related cataracts were the most frequently occurring. Patient age ranged from 18 to 101 y and the vast majority of patients were between 60 and 80 years old. Of the 4151 patients, 64.73%(2687/4151) had a systemic disease. The number of patients increased over the years, with the average number of patients per month being 90.4, 124.83, and 183.42 in 2014, 2015 and 2016, respectively. The average preoperative BCVA was 0.102±0.057 and average postoperative BCVAs at 1 d, 1 wk, and 1 mo post surgery were 0.453±0.264, 0.657±0.285, and 0.734±0.244, respectively. For intraoperative complications, 4.12%(171/4151) had posterior capsule rupture, 0.79%(33/4151) had iris or ciliary body injury, and 0.048%(2/4151) had suprachoroidal hemorrhage. For postoperative complications, 4.38%(182/4151) had cornea edema, 7.78%(323/4151) had intraocular hypertension, 0.096%(4/4151) had IOL toxicity syndrome, 0.28%(12/4151) had retained lens cortex, and 0.048%(2/4151) had hyphema. The delayed discharge rate was 0.82%(44/4151) and the unplanned re-admission to the hospital was 0(0/4151). The patient satisfaction rate was 91.42%(3795/4151). CONCLUSION: Day-case cataract surgery is safe and effective with good prospects for development.

Heart rate variability： a new tool to predict complications in adult cardiac surgery

Heart rate variability （HRV） refers to the variations between consecutive heartbeats, which depend on the continuous modulation of the sympathetic and parasympathetic branches of the autonomic nervous system. HRV has been shown to be effective as a predictor of risk after myocardial infarction and an early warning sign of diabetic neuropathy, and in the cardiology setting is now recognized to be a useful tool for risk-stratification after hospital admission and after discharge. Recent evidences suggest that HRV analysis might predict complications even in patients undergoing cardiac surgery, and the present review summarizes the importance of HRV analysis in adult cardiac surgery and the perspectives for HRV use in current clinical practice. Although future larger studies are warranted before HRV can be included into daily clinical practice in adult cardiac surgery, HRV is a novel tool which might detect autonomic instability in the early postoperative phase and during hospital stay, thus predicting or prompt-diagnosing many of the post-operative complications.

Long-term clinical performance of flapless implant surgery compared to the conventional approach with flap elevation:A systematic review and meta-analysis

BACKGROUND The conventional implant approach involves flap elevation,which may result in increased soft tissue and bone loss and postoperative morbidity.The flapless surgical technique,aided by three-dimensional medical imaging equipment,is regarded as a possible alternative to the conventional approach to alleviate the above issues.Several studies have been performed regarding the role of flapless implant surgery.However,the results are inconsistent and there is no robust synthesis of long-term evidence to better inform surgeons regarding which type of surgical technique is more beneficial to the long-term prognosis of patients in need of implant insertion.AIM To compare the long-term clinical performance after flapless implant surgery to that after the conventional approach with flap elevation.METHODS PubMed,EMBASE,Cochrane Central Register of Controlled Trials,and grey literature databases were searched from inception to 23 September 2019.Randomised controlled trials (RCTs) and cohort studies comparing the long-term clinical performance after flapless implant surgery to that after the conventional approach over a follow-up of three years or more were induded.Meta-analyses were conducted to estimate the odds ratios (ORs) or mean differences (MDs) and their 95 To confidence intervals (CIs) between the long-term implant survival rate,marginal bone loss,and complication rate of the flapless and conventional groups.Subgroup analyses were carried out to account for the possible effects of the guided or free-hand method during flapless surgery.RESULTS Ten articles,including four RCTs and six cohort studies,satisfied the eligibility criteria and nine of them were inclded in the meta-analysis.There was no significant difference between the long-term implant survival rate [OR=1.30,95%CI (0.37,4.54),P=0.68],marginal bone loss [MD=0.01,95%CI (-0.42,0.44),P=0.97],and complication rate [OR=1.44,95%CI (0.77,2.68),P=0.25] after flapless implant surgery and the conventional approach.Moreover,subgroup analyses revealed that there was no statistically significant difference between the implant survival rate [guided:OR=1.52,95%CI (0.19,12.35),P=0.70];free-hand:n=1,could not be estimated),marginal bone loss [guided:MD=0.22,95%CI (-0.14,0.59),P=0.23;free-hand:MD=-0.27,95%CI (-1.10,0.57),P=0.53],or complication rate [guided:OR=1.16,95%CI (0.52,2.63),P=0.71;free-hand:OR=1.75,95%CI(0.66,4.63),P=0.26] in the flapless and conventional groups either with use of the surgical guide or by the free-hand method.CONCLUSION The flapless surgery and conventional approach had comparable clinical performance over three years or more.The guided or free-hand technique does not significantly affect the long-term outcomes of flapless surgery.

Risk factors for anastomotic fistula development after radical colon cancer surgery and their impact on prognosis

BACKGROUND Colon cancer is a common malignant tumor in the gastrointestinal tract that is typically treated surgically.However,postradical surgery is prone to complic-ations such as anastomotic fistulas.AIM To investigate the risk factors for postoperative anastomotic fistulas and their impact on the prognosis of patients with colon cancer.METHODS We conducted a retrospective analysis of 488 patients with colon cancer who underwent radical surgery.This study was performed between April 2016 and April 2019 at a tertiary hospital in Wuxi,Jiangsu Province,China.A t-test was used to compare laboratory indicators between patients with and those without postoperative anastomotic fistulas.Multiple logistic regression analysis was performed to identify independent risk factors for postoperative anastomotic fistulas.The Functional Assessment of Cancer Therapy-Colorectal Cancer was also used to assess postoperative recovery.RESULTS Binary logistic regression analysis revealed that age[odds ratio(OR)=1.043,P=0.015],tumor,node,metastasis stage(OR=2.337,P=0.041),and surgical procedure were independent risk factors for postoperative anastomotic fistulas.Multiple linear regression analysis showed that the development of postoperative anastomotic fistula(P=0.000),advanced age(P=0.003),and the presence of diabetes mellitus(P=0.015),among other factors,independently affected CONCLUSION Postoperative anastomotic fistulas significantly affect prognosis and survival rates.Therefore,focusing on the clinical characteristics and risk factors and immediately implementing individualized preventive measures are important to minimize their occurrence.

Surgical complications in COVID-19 patients in the setting of moderate to severe disease

The coronavirus disease 2019(COVID-19)pandemic has had a considerable impact on the work of physicians and surgeons.The connection between the patient and the surgeon cannot be replaced by telemedicine.For example,the surgical staff faces more serious difficulties compared to non-surgical specialists during the COVID-19 pandemic.The primary concerns include the safest solutions for protecting healthcare staff and patients and the ability to provide adequate surgical care.Additionally,the adverse effects of any surgery delays and the financial consequences complicate the picture.Therefore,patients’admission during the COVID-19 pandemic should be taken into consideration,as well as preoperative measures.The COVID-19 situation brings particular risk to patients during surgery,where preoperative morbidity and mortality rise in either asymptomatic or symptomatic COVID-19 patients.This review discusses the recent factors associated with surgical complications,mortality rates,outcomes,and experience in COVID-19 surgical patients.

ADJUVANT CHEMOTHERAPY FOLLOWING RADICAL SURGERYFOR NON-SMALL CELL LUNG CANCER:A RANDOMIZED STUDY

Objective: To evaluate the efficacy of adjuvant chemotherapy after radical surgery for non-small cell lung cancer (NSCLC). Methods: Seventy patients with NSCLC (stage I–III) undergone radical surgery were randomized into two groups: 35 patients received adjuvant chemotherapy with cyclophosphamide (CTX) 300 mg/m2, vincristine (VCR) 1.4% mg/m2, adriamycin (ADM) 50 mg/m2, lomustine (CCNU) 50 mg/m2 dl, cisplatin (DDP) 20 mg/m2, d1–5, for 4 cycles, and followed by oral Ftorafur (FT-207) 600–900 mg/d for 1 year (adjuvant chemotherapy group). The other 35 patients received surgical treatment only (surgery group). Results: The overall 5-year survival rate was 48.6% in the adjuvant chemotherapy group, and 31.4% in the surgery group, respectively. The difference between the two groups was not statistically significant (P>0.05). The 5-year survival rate of patients in stage III was 44.0% and 20.8% received surgery with and without adjuvant chemotherapy, respectively. The difference between the two groups was statistically significant (P<0.025). The 5-year survival rate of patients in stage I–II in the two groups was 60.0% and 54.5%, respectively (P>0.75). Conclusion: Postoperative adjuvant chemotherapy in NSCLC can improve survival, for those patients in stage III, it suggests significantly 5-year survival rate in the adjuvant chemotherapy group was higher than that in the surgery alone group.

The study of using infrared thermal image to assist surgery of coronary artery bypass

Digital infrared thermography is suitable for monitoring the planar two-dimensional temperature distribution of curved surfaces of objects by sensing their infrared radiation. Cardiac infrared thermography also has a thermal coronary angiography alias. This study proposes a digital image processing methodology for locating blood clot blockage. This methodology contains four consequent processes. The two-dimensional gray scale infrared thermograph pixels are first binarized and classified as background or coronary arteries using multi-thresh adaptive segmentation.The coronary artery contours are extracted from segmented raw pixels using continuous pepper-like pixel removal,erosion,subtraction,recursive neighborhood visiting,contour point-list construction and short edge deletion.In the third process one coronary artery branch is selected by physicians for calculating the longest curved central axis using morphological thinning and neighborhood analysis. In the last process the nearest left and right distances from each pixel along the directional central axis to its corresponding boundary contour are added as the coronary artery variable diameter at the current pixel's position. A variable diameter versus straighten length diagram along this axial curved path is plotted to provide useful physiological information to the physician. An obstruction rate equation is then defined to calculate the possible vascular blockage positions with the local minimal rates. Finally,preoperative cases are tested to prove the predictive positions are correct in comparison to individual patient myocardial perfusion imaging.

Analysis of Flight Punctuality Rate Based on Complex Network

Aviation service plays an indispensable role in the process of social and economic development.In this process,the problem of flight punctuality becomes more and more serious.Flight delay will bring a variety of implicit and explicit losses to individual passengers and airlines,so it is necessary to analyze the influencing factors of flight punctuality rate.Complex network can be used to study various objects with complex relations,obtain the relations of these objects and calculate the influence of different indicators on the objects.This article mainly has carried on the three aspects:Firstly,get the flight data from the Internet,and use the knowledge of the complex network to obtain the data to build into a directed network.Secondly,to analyze the building of directed network,computing network centricity index,study the influence of different centricity index for flight punctuality.Thirdly,get the statistics of airport indicators including network indicators and calculate the correlation of different indicators and punctuality.Through the above three points,the degree of influence of different influencing factors on flight on-time rate is studied,which is the positive influence or the negative influence.The study of these factors will provide some references for the practical application of the improvement of flight punctuality.

A clinical and long-term follow-up study of perioperative sequential triple therapy for gastric cancer

INTRODUCTIONAlthough the long-term postoperative survival rateof gastric cancer(GC) patients has been improvedsignificantly since the local dissection of lymph nodewas widely used in China,yet the low curativeresection rate and the high recurrence rate fromperitoneal and hepatic metastases hinder it fromfurther improvement.To alter the currentunsatisfactory status of GC treatment,a

Enteral stents for the management of malignant colorectal obstruction

Colorectal cancer (CRC) is the 3rd most common cancer in the United States with more than 10000 new cases diagnosed annually. Approximately 20% of patients with CRC will have distant metastasis at time of diagnosis, making them poor candidates for primary surgical resection. Similarly, 8%-25% of patients with CRC will present with bowel obstruction and will require palliative therapy. Emergent surgical decompression has a high mortality and morbidity, and often leads to a colostomy which impairs the patient’s quality of life. In the last decade, there has been an increasing use of colonic stents for palliative therapy to relieve malignant colonic obstruction. Colonic stents have been shown to be effective and safe to treat obstruction from CRC, and are now the therapy of choice in this scenario. In the setting of an acute bowel obstruction in patients with potentially resectable colon cancer, stents may be used to delay surgery and thus allow for decompression, adequate bowel preparation, and optimization of the patient’s condition for curative surgical intervention. An overall complication rate (major and minor) of up to 25% has been associated with the procedure. Long term failure of stents may result from stent migration and tumor ingrowth. In the majority of cases, repeat stenting or surgical intervention can successfully overcome these adverse effects.

Oncology and reproductive outcomes over 16 years of malignant ovarian germ cell tumors treated by fertility sparing surgery

BACKGROUND Malignant ovarian germ cell tumors(MOGCT)are rare and frequently occur in women of young and reproductive age and the oncologic and reproductive outcomes after fertility-sparing surgery(FSS)for this disease are still limited.AIM To evaluate the oncology and reproductive outcomes of MOGCT patients who underwent FSS.METHODS All MOGCT patients who underwent FSS defined as the operation with a preserved uterus and at least one side of the ovary at our institute between January 2005 and December 2020 were retrospectively reviewed.RESULTS Sixty-two patients were recruited for this study.The median age was 22 years old and over 77%were nulliparous.The three most common histology findings were immature teratoma(32.2%),dysgerminoma(24.2%),and yolk sac tumor(24.2%).The distribution of stage was as follows;Stage I,74.8%;stage II,9.7%;stage III,11.3%;and stage IV,4.8%.Forty-three(67.7%)patients received adjuvant chemotherapy.With a median follow-up time of 96.3 mo,the 10-year progressionfree survival and overall survival were 82.4%and 91%,respectively.For reproductive outcomes,of 43 patients who received adjuvant chemotherapy,18(41.9%)had normal menstruation,and 17(39.5%)resumed menstruation with a median time of 4 mo.Of about 14 patients who desired to conceive,four were pregnant and delivered good outcomes.Only one case was aborted.Therefore,the successful pregnancy rate was 28.6%CONCLUSION The oncology and reproductive outcomes of MOGCT treated by FSS are excellent.Many patients show a long survival time with normal menstruation.However,the obstetric outcome is not quite satisfactory.

Optimizing surgical outcomes for elderly gallstone patients with a high body mass index using enhanced recovery after surgery protocol

BACKGROUND Rehabilitation of elderly patients with a high body mass index(BMI)after cholecystectomy carries risks and requires the adoption of effective perioperative management strategies.The enhanced recovery after surgery(ERAS)protocol is a comprehensive treatment approach that facilitates early patient recovery and reduces postoperative complications.AIM To compare the effectiveness of traditional perioperative management methods with the ERAS protocol in elderly patients with gallbladder stones and a high BMI.METHODS This retrospective cohort study examined data from 198 elderly patients with a high BMI who underwent cholecystectomy at the Shanghai Fourth People's Hospital from August 2019 to August 2022.Among them,99 patients were managed using the traditional perioperative care approach(non-ERAS protocol),while the remaining 99 patients were managed using the ERAS protocol.Relevant indicator data were collected for patients preoperatively,intraoperatively,and postoperatively,and surgical outcomes were compared between the two groups.RESULTS The comparison results between the two groups of patients in terms of age,sex,BMI,underlying diseases,surgical type,and preoperative hospital stay showed no statistically significant differences.However,the ERAS group had a significantly shorter preoperative fasting time than the non-ERAS group(4.0±0.9 h vs 7.6±0.9 h).Regarding intraoperative indicators,there were no significant differences between the two groups of patients.However,in terms of postoperative recovery,the ERAS protocol group exhibited significant advantages over the non-ERAS group,including a shorter hospital stay,lower postoperative pain scores and postoperative hunger scores,and higher satisfaction levels.The readmission rate was lower in the ERAS protocol group than in the non-ERAS group(3.0%vs 8.1%),although the difference was not significant.Furthermore,there were significant differences between the two groups in terms of postoperative nausea and vomiting severity,postoperative abdominal distention at 24 h,and daily life ability scores.CONCLUSION The findings of this study demonstrate that the ERAS protocol confers significant advantages in postoperative outcomes following cholecystectomy,including reduced readmission rates,decreased postoperative nausea and vomiting,alleviated abdominal distension,and enhanced functional capacity.While the protocol may not exhibit significant improvement in early postoperative symptoms,it does exhibit advantages in long-term postoperative symptoms and recovery.These findings underscore the importance of implementing the ERAS protocol in the postoperative management of cholecystectomy patients,as it contributes to improving patients'recovery and quality of life while reducing health care resource utilization.

Objective: The objective of our study was to study the surgical activities carried out in the gynecology-obstetrics department of the CHU-YO (Teaching Hospital Yalgado Ouédraogo) from January 1st 2015 to December 31st, 2015. Patients and Methods: This dealt with a cross-cutting descriptive and analytic study with retrospective data collection. Our study has included the female patients who underwent surgery in the operating room and whose medical records were usable. Results: 45% of female patients admitted in the concerned department underwent a surgery. The average age of patients was estimated at 28.02 years ±7 years with extremes of 13 years and 80 years. Obstetrical surgery has involved 89.9% of cases. Female patients have received a loco-regional anesthesia in 92.7% of cases. Emergency surgical operations accounted for 88.8% and caesarean section was the main surgical operation carried out in 87.1% of cases. The mortality rate of the overall surgical operations was 1.04%. Conclusion: A better availability of labile blood products is more likely to reduce the mortality rate of surgical operations under the threshold of 1%.

Retrograde intrarenal surgery for lower pole stones utilizing stone displacement technique yields excellent results

Objective:To evaluate the long-term stone-free rate(SFR)of retrograde intrarenal surgery(RIRS)in the treatment of lower pole renal calculi using only basket relocation and identify independent predictors of stone-free status.Methods:All consecutive patients undergoing RIRS lower pole renal calculi at a single highvolume tertiary center were analyzed retrospectively.Lower pole stones were relocated to the upper pole,where laser lithotripsy was performed.All patients were followed up in the clinic following the surgery and yearly thereafter.The stone-free status was assessed with a combination of an abdominal ultrasound and abdominal X-ray,or an abdominal non-contrast computed tomography if the stones were known to be radiolucent.Results:A total of 480 consecutive patients who underwent RIRS for treatment of lower pole renal calculi,between January 2012 and December 2018,were analyzed from a prospectively maintained database of 3000 ureteroscopies.With a median follow-up time of 18.6 months,the mean SFR was 94.8%.The procedures were unsuccessful in 26(5.4%)patients due to unreachable stones.The median stone size of the unreachable stones was 12 mm(range 10e30 mm).Multivariable logistic regression analysis revealed two predictors of SFR for lower pole stones:a small cumulative stone burden(odds ratio[OR]:0.903,95%confidence interval[CI]:0.867e0.941,p<0.0001)and preoperative ureteral stent insertion(OR:0.515,95%CI:0.318e0.835,pZ0.007).Conclusion:The long-term SFR of RIRS for the treatment of lower pole stones with basket displacement with appropriate patient selection is high.

The laparoscopic rating scale for the evaluation of working conditions for surgical treatment of super-obesity

In this technical note,a novel rating scale(abdominal integral index)was introduced for assessing the conditions of the working laparoscopic space based on linear measurements to select the optimal one or two-stage surgical treatment for super-obesity.Patients with the same height and similar BMI values had different rating scale scores,reflecting different conditions of laparoscopic bariatric surgery.The rating scale helps surgeons and patients make a safe option for surgery,depending on the experience of the surgeon and technical laparoscopic conditions.
