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.

Analysis on relative factors of lymph node metastasis and pattern of postoperative locoreginal relapse of esophageal carcinoma

Objective: We aimed to study the relative factors of lymph node metastasis of esophageal carcinoma, and to analyze the distribution rule of lymph node metastasis of post esophagectomy patients for guiding the radiotherapy. Methods: To collect the patients' data (102 cases) in our hospital from 2001 to 2009, who were found lymph node metastasis confirmed by pathologic in a certain period of time after esophageal cancer surgery. The factors affected the lymph node metastasis in esophageal cancer were analysed by single logistic regression and Logistic Regression Method. To analyze the rule of post-operative lymph node metastasis in different regions, according to the lymph node partition, in accordance with paragraphs of esophageal cancer in different groups. Results: Of the 102 patients after esophageal cancer surgery, who were confirmed by pathological examination, 50 cases had positive lymph node metastasis and 52 cases had negative, the lymph node metastasis rate was 49.0%. Lymph node metastasis rates of different depth, length and paragraph of tumor invasion had statistical difference (P < 0.05). The impact on lymph node metastasis rates of the different age and degree of differentiation had no statistical difference (P > 0.05). Multivariate analysis showed that the lesion length, depth of invasion and paragraph of tumor were meaningful factors affecting the lymph node metastasis. Of the 102 patients, 132 sites node metastasis were found by imaging study and histopathology with lower neck and supraclavicular node 59 (44.70%), upper mediastinum node 51 (38.64%), A-P windows node 1 (0.76%), anterior mediastinum node 1 (0.76%), Subcarinal node 5 (3.79%), paraesopha- geal node 3 (2.27%), hilar node 3 (2.27%), abdominal node 9 (6.82%). Conclusion: The length and depth of invasion, and paragraph of esophageal cancer are meaningful factors that affect the lymph node metastasis. The longer of lesion, deeper of infiltration and lower of paragraph, the easier to get independently lymph node metastasis. The postoperative lymph node metastasis was mainly distributed in the lower neck and supraclavicular region and upper mediastinal region, which is the focus of postoperative radiotherapy.

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.

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.

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.

Model for end-stage liver disease score versus Child score in predicting the outcome of surgical procedures in patients with cirrhosis

AIM： To determine factors affecting the outcome of patients with cirrhosis undergoing surgery and to compare the capacities of the Child-Turcotte-Pugh （CTP） and model for end-stage liver disease （MELD） score to predict that outcome. METHODS： We reviewed the charts of 195 patients with cirrhosis who underwent surgery at two teaching hospitals over a five-year period. The combined endpoint of death or hepatic decompensation was considered to be the primary endpoint. RESULTS： Patients who reached the endpoint had a higher MELD score, a higher CTP score and were more likely to have undergone an urgent procedure. Among patients undergoing elective surgical procedures, no statistically significant difference was noted in the mean MELD （12.8 ＋ 3.9 vs 12.6 ＋ 4.7, P = 0.9） or in the mean CTP （7.6 ± 1.2 vs 7.7 ± 1.7, P = 0.8） between patients who reached the endpoint and those who did not. Both mean scores were higher in the patients reaching the endpoint in the case of urgent procedures （MELD： 22.4 ± 8.7 vs 15.2 ± 6.4, P = 0.0007; CTP： 9.9 ± 1.8 vs 8.5 ± 1.8, P = 0.008）. The performances of the MELD and CTP scores in predicting the outcome of urgent surgery were only fair, without a significant difference between them （AUC = 0.755 ± 0.066 for MELD vs AUC = 0.696 ± 0.070 for CTP, P = 0.3）. CONCLUSION： The CTP and MELD scores performed equally, but only fairly in predicting the outcome of urgent surgical procedures. Larger studies are needed to better define the factors capable of predicting the outcome of elective surgical procedures in patients with cirrhosis.equally, but only fairly in predicting the outcome of urgent surgical procedures. Larger studies are needed to better define the factors capable of predicting the outcome of elective surgical procedures in patients with cirrhosis.
