Laparoscopic versus Abdominal Myomectomy: Surgical and Post-Operative Outcomes in CHRACERH-Yaounde

Introduction: Fibroid benign tumour of the uterus can be operated either by laparotomy or laparoscopy. Laparoscopy is not well vulgarised in our settings. Objective: The main objective was to compare the surgical and post-operative outcomes of laparoscopic versus abdominal myomectomy. Methods: We performed a comparative analytical cross sectional study from 1st January 2016 to 31st March 2018 consisted of two groups: group 1 of women who underwent laparoscopic myomectomy (LM) and group 2 of women who underwent abdominal myomectomy (AM). The data collected was entered in Epi Info 7.2 version and exported to IBM SPSS Statistics version 22 for analysis. We used alpha error margin of 5% and confidence interval of 95%. Results: We enrolled 50 cases of myomectomy consisted of 33 (66.0%) files for AM and 17 (34.0%) files for LM. The clinical presentation of fibroid was similar in both groups. The main operation time (H) was (1.27 ± 0.13) for laparoscopy which is much less than (2.05 ± 0.07) for laparotomy group (p = 0.006). In AM group we had 04 post-operatory complications against zero complications in LM group but the difference was not statistically significant (p = 0.387). In the second look laparoscopy, the types of adhesions were not statistically significant (p = 0.471). Conclusion: Laparoscopic offers advantages compared to abdominal myomectomy.

Risk Factor of Postoperative Lumbar Surgical Site Infection: A Literature Review

Nowadays there have been various advanced techniques to overcome disparate types of lumbar degenerative diseases. However, post-operation complications such as Surgical Site Infection (SSI) still give the surgeon with a big challenge. This article is going to study the risk factor that causes the lumbar SSI by reviewing all the articles that can be assessed through PubMed, websites of science and other internet data base. Numerous articles have stated different reported prevalence rates of 0.7% to 16% for surgical site infection. This article will document the most common and significant risk factors for SSI. At last, we suggest that there should be preoperative patient screening and postoperative internal environment maintenance, this will be the best way to reduce postoperative SSI rate or prevent SSI from happening.

Radiation therapy prior to a pancreaticoduodenectomy for adenocarcinoma is associated with longer operative times and higher blood loss

BACKGROUND Pancreatic adenocarcinoma is currently the fourth leading cause of cancer-related deaths in the United States.In patients with“borderline resectable”disease,current National Comprehensive Cancer Center guidelines recommend the use of neoadjuvant chemoradiation prior to a pancreaticoduodenectomy.Although neoadjuvant radiotherapy may improve negative margin resection rate,it is theorized that its administration increases operative times and complexity.AIM To investigate the association between neoadjuvant radiotherapy and 30-d morbidity and mortality outcomes among patients receiving a pancreaticoduodenectomy for pancreatic adenocarcinoma.METHODS Patients listed in the 2015-2019 National Surgery Quality Improvement Program data set,who received a pancreaticoduodenectomy for pancreatic adenocarcinoma,were divided into two groups based off neoadjuvant radiotherapy status.Multivariable regression was used to determine if there is a significant correlation between neoadjuvant radiotherapy,perioperative blood transfusion status,total operative time,and other perioperative outcomes.RESULTS Of the 11458 patients included in the study,1470(12.8%)underwent neoadjuvant radiotherapy.Patients who received neoadjuvant radiotherapy were significantly more likely to require a perioperative blood transfusion[adjusted odds ratio(aOR)=1.58,95%confidence interval(CI):1.37-1.82;P<0.001]and have longer surgeries(insulin receptor-related receptor=1.14,95%CI:1.11-1.16;P<0.001),while simultaneously having lower rates of organ space infections(aOR=0.80,95%CI:0.66-0.97;P=0.02)and pancreatic fistula formation(aOR=0.50,95%CI:0.40-0.63;P<0.001)compared to those who underwent surgery alone.CONCLUSION Neoadjuvant radiotherapy,while not associated with increased mortality,will impact the complexity of surgical resection in patients with pancreatic adenocarcinoma.

Intraoperative photodynamic therapy for tracheal mass in non-small cell lung cancer:A case report

BACKGROUND Tracheal neoplasms represent less than 0.1%of all malignancies and have no established treatment guidelines.Surgical resection with reconstruction is the primary treatment.This study demonstrates successful treatment of concurrent lung and tracheal tumors using surgical excision and intraoperative photodynamic therapy(PDT),highlighting the effectiveness and safety of this approach.CASE SUMMARY A 74-year-old male with a history of smoking and chronic obstructive pulmonary disease was diagnosed with tracheal squamous cell carcinoma and right lower lobe adenocarcinoma.A multidisciplinary team created a treatment plan involving tumor resection and PDT.The tracheal tumor was removed through a tracheal incision and this was followed by intraluminal PDT.The trachea was repaired and a right lower lobectomy was performed.The patient received a second PDT treatment postoperatively and was discharged 10 d after the tracheal surgery,without complications.He then underwent platinum-based chemotherapy for lymphovascular invasion of lung cancer.Three-month postoperative bronchoscopy revealed normal tracheal mucosa with a scar at the resection site and no evidence of tumor recurrence in the trachea or lung.CONCLUSION Our case of concurrent tracheal and lung cancers was successfully treated with surgical excision and intraoperative PDT which proved safe and effective in this patient.

OBSERVATION ON THERAPEUTIC EFFECTS OF ACUPUNCTURE IN 206 CASES WITH POSTOPERATIVE COMPLICATION OF ANUS AND INTESTINE

The authors have treated postoperative complication of anus and intestine by usingacupuncture at main point Chengshan(BL 57) with cool-producing needling manipulation. Therapeuticeffects of the treatment on postoperative severe pain, retention of urine, constipation, and bleedingwere observed clinically. Results indicated that the cure rate was 97. 6 % and the total effective ratewas 100%. Strong stimulation of Chengshan(BL 57) point improved mainly postoperative edema,spasm, local edema. The improvement of hyperemia and spasm is a ma jor factor of curing various postoperative complication of the anus and intestine. The therapeutic method has advantages of using lesspoints, rapidly producing effects, shorter therapeutic course, suffering little for patients, and no sideeffect.

Non-robotic minimally invasive gastrectomy as an independent risk factor for postoperative intra-abdominal infectious complications: A single-center, retrospective and propensity score-matched analysis

BACKGROUND Minimally invasive surgery for gastric cancer(GC) has gained widespread use as a safe curative procedure especially for early GC.AIM To determine risk factors for postoperative complications after minimally invasive gastrectomy for GC.METHODS Between January 2009 and June 2019, 1716 consecutive patients were referred to our division for primary GC. Among them, 1401 patients who were diagnosed with both clinical and pathological Stage Ⅲ or lower GC and underwent robotic gastrectomy(RG) or laparoscopic gastrectomy(LG) were enrolled. Retrospective chart review and multivariate analysis were performed for identifying risk factors for postoperative morbidity.RESULTS Morbidity following minimally invasive gastrectomy was observed in 7.5% of the patients. Multivariate analyses demonstrated that non-robotic minimally invasive surgery, male gender, and an operative time of ≥ 360 min were significant independent risk factors for morbidity. Therefore, morbidity was compared between RG and LG. Accordingly, propensity-matched cohort analysis revealed that the RG group had significantly fewer intra-abdominal infectious complications than the LG group(2.5% vs 5.9%, respectively;P = 0.038), while no significant differences were noted for other local or systemic complications.Multivariate analyses of the propensity-matched cohort revealed that non-robotic minimally invasive surgery [odds ratio = 2.463(1.070–5.682);P = 0.034] was a significant independent risk factor for intra-abdominal infectious complications.CONCLUSION The findings showed that robotic surgery might improve short-term outcomes following minimally invasive radical gastrectomy by reducing intra-abdominal infectious complications.

Simultaneous operative treatment of patients with primary liver cancer associated with portal hypertension

Objective: To explore the operative procedure for pa-tients with primary liver cancer associated with portalhypertension (PLCPH).Methods: We analyzed retrospectively the effect of op-erative procedure for 9 patients with PLCPH compli-cated by severe esophageal varicosity and hyper-splenism.Results: All patients underwent liver resection andpericardiac devascularization with splenectomy. Of the9 patients, 2 died from liver cancer recurrence sepa-rately 13 and 16 months after operation, and 1 diedfrom massive duodenal ulcer bleeding and multipleorgans failure. Six patients survived 3, 4, 8, 10, 12 and25 months after operation.Conclusions: The patients with PLCPH undergoing si-multaneous operation could acquire curative effect ascompared with those who underwent liver resec-tion. This operation is beneficial to the patients withpoor liver function.

Correlation analysis of compromised immune function with perioperative sepsis in HIV-positive patient

Objective: To investigate the relationship between immune function and perioperative sepsis in HIV-positive patients. Methods: Retrospective analysis of 144 HIV-positive patients surgically treated from Oct 2008 to Dec 2010 in Shanghai Public Health Clinical Center. The patients were divided into four groups based on their CD4+ T cells counts in preoperative period: group A (0 – 99 cell/ul), group B (100 – 199 cell/ul),group C (200 – 349 cell/ul),group D (≥350 cell/ul). All patients had received standardized surgical procedures, careful surgical routines were applied. To reduce operational damage, conventional antibi-otics, anti-TB, anti-fugal, antiretroviral therapies were used to prevent infection and promptly treatment of complications. Results among 144 HIV-positive patients (male 133 and female 11, aged 42.6 ± 12.5), 80 patients got perioperative sepsis (14 cases in preoperative period and 66 cases in postoperative period). 64 cases did not get sepsis. The average CD4+ T cell count was 276.97 ± 137.91 in preoperative period of patients without sepsis, which was significant higher than the patients with preoperative sepsis (151.29 ± 110.64) and patients with postope- rative sepsis(161.14 ± 128.45) (F = 13.91, P χ2 = 23.680, P +T cells (r = –0.987, P = 0.013). Conclusions With the decrease of preoperative CD4+T cells, the risk of perioperative sepsis had notable increase. Complete evaluation of surgical risk and suitable perioperative treatments may obtain better effect for the patients infected HIV.

High Supracostal Percutaneous Nephrolithotomy Access: Assessing Safety in Access above the Eleventh Rib after Performing Preoperative Planning with Computed Tomography

Objective: To determine if supracostal renal access above the 11th rib during percutaneous nephrolithotomy (PCNL) is a safe option in carefully selected patients determined by preoperative computed tomography (CT) imaging. Patients and Methods: We retrospectively isolated 142 patients who underwent access above the eleventh rib during PCNL, which we term “high supracostal renal access.” We then compared these patients to 113 individuals who underwent access below the twelfth rib. Renal access was achieved by the operative surgeon with fluoroscopic guidance in conjunction with pre-operative computed tomography (CT) scan. Outcomes were compared. Results: Overall surgical outcomes were equivalent when comparing high supracostal versus subcostal access sites. As expected due to proximity, pleural complications occurred in 4% of the high supracostal group (n = 6) compared with 0% of the control (subcostal) group (p = 0.035). Of these six complications, three were managed conservatively with observation and two required cardio-thoracic intervention with video-assisted thoracoscopic pleural repair (1%). In the remaining case, the patient was preoperatively consented for placement of a thoracostomy tube, which was placed during the procedure, due to the difficult location of her upper pole stone and closely adjacent low-lying pleura, and the planned transpleural approach. Hospital stay was not significantly pro-longed between the high supracostal access and subcostal access groups, with an average length of stay of 2.2 ± 2.1 days and 2.0 ± 1.9 days (p = 0.59) respectively. Conclusions: Careful, systematic preoperative planning based on CT and fluoroscopic imaging allows for a confident understanding of a “safety zone” in placement and dilatation of renal access points during PCNL. We have shown that planned upper pole renal access above the 11th rib is achievable with acceptable morbidity and excellent success rates.

Operating Room Nurses’ Role in Multidisciplinary Surgical Coordination for a Patient with a Large Abdominal Tumor and Multiple Pelvic Fractures

In this study,we have summarized the coordination of operating room nurses participating in the multidisciplinary team in diagnosing and treating a patient with a large abdominal tumor and multiple pelvic fractures.To perform surgical treatment on patients with various conditions,it is crucial to consider the patients from a holistic perspective.Thus,the existing medical model has shifted from a“disease-centered”approach focusing on single-disciplinary diagnosis and treatment,to a“patient-centered”approach that involves multiple disciplines in diagnosis and therapy.Operating room nurses,as crucial collaborators of surgeons,should make necessary adjustments to enhance their comprehension of patients,improving the overall quality of surgical coordination.

Preoperative rectal tumor embolization as an adjunctive tool for bloodless abdominoperineal excision:A case report

BACKGROUND Abdominoperineal excision(APE)-related hemorrhage can be challenging due to difficult access to pelvic organs and the risk of massive blood loss.The objective of the present study was to demonstrate the use of preoperative embolization(PE)as a strategy for blood preservation in a patient with a large low rectal tumor with a high risk of bleeding,scheduled for APE.CASE SUMMARY A 56-year-old man presented to our institution with a one-year history of anal bleeding and rectal tenesmus.The patient was diagnosed with bulky adenocarcinoma limited to the rectum.As the patient refused any clinical treatment,surgery without previous neoadjuvant chemoradiation was indicated.The patient underwent a tumor embolization procedure,two days before surgery performed via the right common femoral artery.The tumor was successfully devascularized and no major bleeding was noted during APE.Postoperative recovery was uneventful and a one-year follow-up showed no signs of recurrence.CONCLUSION Therapeutic tumor embolization may play a role in bloodless surgeries and increase surgical and oncologic prognoses.We describe a patient with a bulky low rectal tumor who successfully underwent preoperative embolization and bloodless abdominoperineal resection.

Comparison of Surgical Techniques Used in Treating Acromioclavicular Dislocation in Patients Participating in Sports: A Systematic Review

Introduction: The acromioclavicular joint is a superficial diarthrodial joint that surrounds the medial articular facet of the acromion and the distal portion of the clavicle. Due to its anatomy and biomechanics, it is highly susceptible to trauma and in young men who play contact sports, acromioclavicular dislocation is common. This article aimed to systematically review the literature and compare the surgical techniques used in the treatment of acromioclavicular dislocation in patients who practice sports. Methods: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Eligible studies for this systematic review included articles in English or Spanish published between 2013 and 2023, which mention the occurrence of acromioclavicular dislocation during sports practices. Additionally, only studies that addressed the surgical treatment of acromion-clavicular dislocation and contained original data on the topic were included. Results: We found 144 eligible studies after searching the LILACS and PubMed databases. Based on the inclusion and exclusion criteria and the reviewers’ consensus, we selected four studies for the systematic review. 133 patients with AC joint displacement were evaluated. Mean Age: approximately 31.90 years. 81.92 of these injuries occurred during sports practice. Surgical Procedures Used: titanium plates fixation (49 patients), arthroscopy (24), single tunnel technique (30) and coracoid sling technique (30). The results of the visual analog scale and Constant-Murley scores varied between the techniques used. Twenty-two complications after surgical treatment were identified. Conclusion: A significant variability of operative techniques can be used in the surgical approach of acromioclavicular dislocation, such as arthroscopy, single tunnel, coracoid sling and titanium plates. Although it presented excellent functional results compared to the other three techniques evaluated by this review, using titanium plates is not the gold standard since other techniques not assessed by this work may be more effective.

Investigation on complementarity between total mesorectal excision and radical resection in relation to postoperative local recurrence in patients receiving anus-reserve operation on rectal cancer

Objective:To investigate the difference and complementarity between total mesorectal excision(TME)and radical resection in relation to postoperative local recurrence in patients receiving anus-reserve operation on rectal cancer.Methods:Clinical data of 81 cases during a period from 1975 to 2001 were retrospectively analyzed.Results:In the 81 cases with local recurrence,49 of them laid to anastomosis and mesorectum,17 lymph nodes and 15 multi-site relapse.The choice of operative procedure included abdominoperineal resection in 58 cases,Hartmann’s operation in 4 cases,simple double-pelvic stoma in 12 cases,exploration in 7 cases,and total pelvic or rear-pelvic resection in combination with other organs in 6 cases. The rate of resection was 84.0%(68/81).32 cases reached clinical radical degree,and the rate of radical resection was 39.5% (32/81).The 5-year survival rate was 34.4%(11/32).Conclusion:Based on actual condition of the patients,attention to radi- cal resection and total mesorectal excision are necessary,and reasonable adoption of the operative procedure could reduce the local recurrence of rectal cancer.

Intraoperative Glycaemia Following Paracetamol with and without Glucose: A Randomized-Controlled Trial

Background: Hyperglycaemia is conversely a risk factor for perioperative complications. We are currently using a generic 3.3 g glucose containing formula of intravenous 1000 mg paracetamol for perioperative analgesia. Our main goal was to compare the trends of glycaemic values after administration of a generic 3.3 g glucose containing formula with a non-glucose containing branded formula of intravenous 1000 mg paracetamol. Methods: A exploratory proof-of-concept randomized clinical trial was conducted with 150 patients scheduled for elective gynaecologic. Patients were randomly assigned into three groups: control group (saline);active-control group: intraoperative administration of a branded non-glucose containing 1000 mg paracetamol formula;experimental group: intraoperative administration of a generic 3.3 g glucose containing 1000 mg paracetamol formula. The primary outcome was mean change from baseline in glaucoma. In case significant differences were found, the following secondary outcomes were explored: the proportion of patients with high glycaemia values (>150 mg/dL) and the proportion of patients with negative glycaemic variation. Results: Mean glycaemia change was higher after generic 3.3 g glucose containing paracetamol formula both in comparison to placebo (16.3 mg/dL [95% CI: 6.1 to 26.6]) and active-control (19.1 mg/dL [8.2 to 30.0] groups. Similar results were found in the intention-to-treat analysis. In only the experimental group, patients had high glycaemic values (11.3%). Conclusions: This study showed that in non-diabetic, under non-cardiac surgery, administration of a generic glucose-containing formula of intravenous 1000 mg paracetamol was associated with poorer glycaemic control. These results raise the question of a possible increased risk among these patients. Further studies using diabetic patients are recommended.

Endoscopic treatment of biliopancreatic pathology in patients with Whipple's pancreaticoduodenectomy surgical variants: Lessons learned from single-balloon enteroscopy-assisted ERCP

Background: Endoscopic treatment of biliopancreatic pathology is challenging due to surgically altered anatomy after Whipple's pancreaticoduodenectomy. This study aimed to evaluate the feasibility and safety of single-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography(SBE-ERCP) to treat biliopancreatic pathology in patients with Whipple's pancreaticoduodenectomy surgical variants. Methods: We retrospectively analyzed 106 SBE-ERCP procedures in 46 patients with Whipple's variants. Technical and clinical success rates and adverse events were evaluated. Results: Biliary SBE-ERCP was performed in 34 patients and pancreatic SBE-ERCP in 17, including 5 with both indications. From a total of 106 SBE-ERCP procedures, 76 were biliary indication with technical success rate of 68/76(90%) procedures and clinical success rate of 30/34(88%) patients. Mild adverse event rate was 8/76(11%), without serious adverse events. From a total of 106 SBE-ERCP procedures, 30 were pancreatic indication with technical success rate of 24/30(80%) procedures( P = 0.194 vs. biliary SBEERCP) and clinical success rate of 11/17(65%) patients( P = 0.016 vs. biliary SBE-ERCP). Mild adverse event rate was 6/30(20%)( P = 0.194 vs. biliary SBE-ERCP), without serious adverse events. After SBE-ERCP failure, endoscopic ultrasound-guided drainage, percutaneous drainage and redo surgery were alternative therapeutic options. Conclusions: Biliopancreatic pathology after Whipple's pancreaticoduodenectomy variants can be treated using SBE-ERCP without serious adverse events. Technical and clinical success rates are high for biliary indications, whereas clinical success rate of pancreatic indications is significantly lower. SBE-ERCP can be considered as first-line treatment option in this patient group with surgically altered anatomy.

Timing of surgical operation for patients with intra-abdominal infection:A systematic review and meta-analysis

BACKGROUND Intra-abdominal infections(IAIs)is the most common type of surgical infection,with high associated morbidity and mortality rates.In recent years,due to the use of antibiotics,various drug-resistant bacteria have emerged,making the treatment of abdominal infections more challenging.Early surgical exploration can reduce the mortality of patients with abdominal infection and the occurrence of complications.However,available evidence regarding the optimal timing of IAI surgery is still weak.In study,we compared the effects of operation time on patients with abdominal cavity infection and tried to confirm the best timing of surgery.AIM To assess the efficacy of early vs delayed surgical exploration in the treatment of IAI,in terms of overall mortality.METHODS A systematic literature search was performed using PubMed,EMBASE,Cochrane Central Register of Controlled Trials,Ovid,and ScienceDirect.The systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses method.Based on the timing of the surgical operation,we divided the literature into two groups:Early surgery and delayed surgery.For the early and delayed surgery groups,the intervention was performed with and after 12 h of the initial surgical intervention,respectively.The main outcome measure was the mortality rate.The literature search was performed from May 5 to 20,2021.We also searched the World Health Organization International Clinical Trials Registry Platform search portal and ClinicalTrials.gov on May 20,2021,for ongoing trials.This study was registered with the International Prospective Register of Systematic Reviews.RESULTS We identified nine eligible trial comparisons.Early surgical exploration of patients with IAIs(performed within 12 h)has significantly reduced the mortality and complications of patients,improved the survival rate,and shortened the hospital stay.CONCLUSION Early surgical exploration within 12 h may be more effective for the treatment of IAIs relative to a delayed operation.

Operating procedures of traditional Chinese medicine breast massage

Traditional Chinese medicine breast massage,also known as breast Tuina or manual expression of breast milk,is a technique of using certain manipulations to act on specific positions or acupoints of the breast to promote blood and lymphatic circulation of breast and facilitate the discharge of stagnant milk.This technique is widely used in China to treat breastfeeding problems such as breast engorgement,mastitis,and postpartum hypogalactia.In this article,we introduce the definition and standardization process of breast massage,elaborate the operating procedures of breast massage in detail,and summarize and discuss the current situation of its clinical application,so as to provide a reference for its wide application and in‑depth research.

Preventing surgical site infection using operating room bundle of care in patients undergoing elective exploratory laparotomy cholecystectomy surgery

Objective:Surgical procedures manifest immense risks to patients.One of the adverse events that healthcare professionals see as a threat to the patient’s health is the development of complications known as surgical site infection(SSI).Although several effor ts are being under taken to determine the proper means to reduce such complications,there is still a high incidence of SSI worldwide.Surgery requires knowledge in infection control and high precision in maintaining a clean surgical site.This study tested the effectiveness of an operating room(OR)bundle of care in preventing SSI in patients undergoing elective exploratory laparotomy cholecystectomy surgery.Methods:A quasi-experimental pretest and posttest design was utilized to determine its effectiveness.The study was composed of 60 par ticipants divided into two groups:30 subjects were selected to receive the OR bundle of care,while the other 30 subjects received the usual care.The groupings were determined through a systematic random sampling technique.The OR bundle of care had three interventions,namely:(1)maintaining perioperative normothermia,(2)no pre-operative surgical site hair removal,and(3)changing gloves before abdominal wall closure.These patients were evaluated using the standard instrument,Bates–Jensen Wound Assessment Tool(BWAT)in the post-intervention phases of the wound healing process,which are as follows:hemostasis,inflammatory,and proliferative phases.To describe the difference in the patients’wound status after implementation of the OR bundle of care in each post-intervention phase,Friedman’s test was used.To describe the difference in the patients’wound status in both groups after implementation of the OR bundle of care,the Mann–Whitney U test was used.Results:The patient’s wound status was lower,indicating a more healing process.Differences between the wound status of the control and the experimental group were observed on the third postoperative day.This indicates that the experimental group’s wound status healed much faster and more effectively than the control group based on the BWAT scoring severity scoring.A significant difference in the patient’s wound status from the hemostasis phase compared with the proliferative phase was observed.Conclusions:The OR bundle of care has been shown to be effective in preventing SSI in patients who had undergone exploratory laparotomy cholecystectomy surgery in the selected hospital,if there is uniform and consistent implementation of the said intervention.

Preoperative Evaluation and Midterm Outcomes after the Surgical Correction of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery in 50 Infants and Children

Background： Anomalous origin of the left coronary artery （LCA） from the pulmonary artery （ALCAPA） is a rather rare congenital anomaly that has a profound effect on heart function. This study aimed to retrospectively illustrate the perioperative clinical features, therapy experience, and midterm outcomes after surgical correction, and to determine the value of left ventricular ejection fraction （LVEF） and myocardial viability in differentiating critically ill patients among infants and children with ALCAPA. Methods： From April 1999 to March 2013, infants and children patients diagnosed with ALCAPA in Beijing Fuwai Hospital were analyzed. Clinical data of patients were summarized and retrospectively analyzed. All patients were divided into two groups according to LVEF level （Group 1： LVEF 〉50%, or Group 2： LVEF ≤50%） to compare perioperative and follow-up variables. Effect of myocardial viability evaluated according to myocardial perfusion/18F-fluorodeoxyglucose （FDG） imaging on the clinical variables was also analyzed. Results： A total of 50 patients with ALCAPA （male/female： 29/21; median age： 3.1 years [range： 4 months to 18 years]） were included. Younger age, lower weight, intercoronary collaterals （ICC） dysplasia, ratio of the proximal right coronary artery diameter to the aortic root diameter 〈0.2, and larger cardiothoracic ratio （CTR） were more frequently found in Group 2 than those in Group 1. Forty-seven patients underwent cardiac surgery. The times of cross-clamp and cardiopulmonary bypass were not different between the two groups; however, the duration of mechanical ventilation and postoperative Intensive Care Unit stay were longer in Group 2 than those in Group 1. Follow-ups were possible in 38 patients （80.9%）; median time： 84.5 months （range： 49 months to 216 months）. There was one late sudden death with simple ligation of the LCA at 8 months after surgery. No severe complications and reoperation occurred. The relationship of the grades of myocardial viability and clinical features was analyzed in 15 patients with myocardial perfusion/18F-FDG imaging, and the results showed that myocardial viability correlated well with LVEF, CTR, abnormal Q waves, and left ventricular end-diastolic dimension. It was not correlated with age, mitral regurgitation, and ICC. Heart implantation was decided in one patient with little viable myocardium; however, this patient died 2 months after the diagnosis while waiting for transplantation. Two patients with no viable myocardium in the area of aneurysm had aneurysmectomy concomitantly. Conclusions： In infants and children withALCAPA, heart function and myocardial viability are closely related to clinical features. LVEF and the grades of myocardial viability can differentiate high-risk patients before surgery and in the early stage of recovery after surgery. The area and extent of myocardial infarction are also crucial in making preoperative clinical decisions. However, even in patients with depressed ventricular function and severe myocardial infarction, the midterm follow-up showed satisfactory recovery of cardiac function after the successful restoration of a dual-coronary arterial system.

CHANGES OF INTERLEUKIN-6 AND RELATED FACTORS AS WELL AS GASTRIC INTRAMUCOSAL pH DURING COLORECTAL AND ORTHOPAEDIC SURGICAL PROCEDURES

Objective To investigate the changes of perioperative serum levels of interleukin-6(IL-6), C-reactive protein (CRP), and cortisol, as well as gastric intramucosal pH (pHi) and plasma lactate, aiming to compare systemic changes and tissue perfusion during colorectal and orthopaedic surgical procedures. Methods Twenty patients were randomly assigned to two groups, 10 cases of operation on vertebral canal, 10 cases of colorectal radical operation.Venous blood was drawn at 1 day before operation, 2, 4, and 6 hours following skin incision, and 1 day after operation, in order to measure serum IL-6, CRP, and cortisol.pHi and plasma lactate were also measured at the same time points.Results Serum concentrations of IL-6 and cortisol increased gradually following operation, reaching the peak value at 6 hours from the beginning of operation.CRP was not detectable until the first day after operation.Peak concentration of IL-6 had positive relationship with CRP.These variables changed more significantly in colorectal group than that in orthopaedic group (P<0.05).pHi decreased gradually, reaching the lowest level at 4 hours from the beginning of operation, and to more extent in colorectal group than that in orthopaedic group (P<0.05).Conclusion IL-6 may reflect tissue damage more sensitively than CRP.Colorectal surgery might induce systemic disorder to more extent, in terms of immuno-endocrinal aspect as well as tissue perfusion, reflected with pHi.
