Outpatient management of biliary colic: a prospective observational study of prescribing habits and analgesia effectiveness

Acupuncture on GB34 for immediate analgesia and regulating pain-related anxiety for patients with biliary colic: a protocol of randomized controlled trial

BACKGROUND

Biliary colic (BC) is a frequent hepatobiliary disorder encountered in emergency departments. Acupuncture may be effective as an alternative and complementary medicine for BC. Nonetheless, rigorous trials investigating its efficacy are lacking. Therefore, the aim of this study protocol is to determine whether acupuncture provides immediate relief of pain and associated symptoms in BC patients.

METHOD

Eighty-six participants who aged from 18 to 60 years with BC will be recruited in the First People's Hospital of Longquanyi District, Chengdu (West China Longquan Hospital Sichuan University). All participants will be allocated into two treatment groups including acupuncture group and sham acupuncture group using a 1:1 ratio. Each group will only receive a single 30-min needle treatment while waiting for their test results after completing the routine examination for BC. The primary outcome of the study is to assess the change in pain intensity after the 30-min acupuncture treatment. The secondary outcomes of the study include the change in pain intensity at various time points, the degree of gastrointestinal symptoms at different time points, the level of anxiety experienced during pain episodes at different time points, the score of Pain Anxiety Symptoms Scale-20 (PASS-20), the score of Fear of Pain Questionnaire-III (FPQ-III), and the score of Pain Catastrophizing Scale (PCS), among others.

DISCUSSION

The results of this research will provide substantial evidence regarding the efficacy of acupuncture in alleviating symptoms associated with BC.

Impact of Resident Post-Graduate Year on Laparoscopic Cholecystectomy Outcomes

Introduction Laparoscopic cholecystectomy is a minimal access procedure in which the gallbladder is removed by laparoscopic techniques. Effective training for laparoscopic surgery should focus on not only understanding the anatomy and procedural steps but also acquiring the specific gestures and techniques of this type of surgery that may differ from those used in traditional open surgery. The aim of our study was to analyze whether the laparoscopic cholecystectomy performed by surgeons in training is a safe procedure. Material and methods This is a retrospective review of 433 patients who were divided into two groups: laparoscopic cholecystectomies performed by trainees and those performed by senior surgeons. Results Around 66% of surgeries were performed by resident surgeons. There was no demographic difference between residents and senior surgeons. Operative time was significantly longer in the residents' group compared to senior surgeons' group (96 minutes vs 61 minutes; p<0.001). The overall intra- and post-operative complication rates were 3.1% and 2.5%, respectively, with no significant difference between the two groups (p=0.368 and p=0.223). Conversion to open laparotomy was required in 8% of cases in each group (p=0.538). The mean length of hospital stay after surgery was significantly longer in patients operated by residents (p<0.001). We did not notice any case of mortality in both groups.

Comparative Analysis of the Acute Appendicitis Management in Children Before and During the COVID-19 Pandemic

Introduction: Acute appendicitis (AA) is one of the most common emergency surgical diseases in pediatric population. Herein, we aimed to compare the incidence and severity of AA before and during the COVID-19 outbreak. Methods: This multicenter study was conducted in three medical faculty hospitals between the periods of 15 March-30 June 2019 (Group A), and the pandemic period of 15 March-30 June 2020(Group B). We evaluated the clinicopathological characteristics of the patients in each group due to age, gender, serum leukocyte, C-reactive protein, radiological imaging use of postop peritoneal drain and presence of serious complications. Results: A total of 141 patients were identified, 64 in Group A and 77 in Group B. We found higher complication rates in Group B. Fewer patients applied in Group B, but a higher rate of AA was diagnosed. During the COVID-19 period, more patients were admitted with the later stages of the AA and with significant complications. Radiological imaging of patients with appendicitis in Group B showed more severe disease than cases in Group A. Conclusion: Higher rate of perforated and complicated appendicitis in the pandemic period was due to misdiagnosis/delayed diagnosis in primary care centers as a result of fear from contagious coronavirus. While the period of the COVID - 19 pandemic presents difficulties in treating infected patients, we would like to emphasize the importance of a comprehensive assessment and physical examination in children with suspected surgical conditions.

Immediate acupuncture with GB34 for biliary colic: protocol for a randomised controlled neuroimaging trial

INTRODUCTION

As the main manifestation of gallstone disease, biliary colic (BC) is an episodic attack that brings patients severe pain in the right upper abdominal quadrant. Although acupuncture has been documented with significance to lead to pain relief, the immediate analgesia of acupuncture for BC still needs to be verified, and the underlying mechanism has yet to be covered. Therefore, this trial aims first to verify the immediate pain-alleviation characteristic of acupuncture for BC, then to explore its influence on the peripheral sensitised acupoint and central brain activity.

METHODS AND ANALYSIS

This is a randomised controlled, paralleled clinical trial, with patients and outcome assessors blinded. Seventy-two patients with gallbladder stone disease presenting with BC will be randomised into a verum acupuncture group and the sham acupuncture group. Both groups will receive one session of immediate acupuncture treatment. Improvements in patients' BC will be evaluated by the Numeric Rating Scale, and the pain threshold of acupoints will also be detected before and after treatment. During treatment, brain neural activity will be monitored with functional near-infrared spectroscopy (fNIRS), and the needle sensation will be rated. Clinical and fNIRS data will be analysed, respectively, to validate the acupuncture effect, and correlation analysis will be conducted to investigate the relationship between pain relief and peripheral-cerebral functional changes.

ETHICS AND DISSEMINATION

This trial has been approved by the institutional review boards and ethics committees of the First Teaching Hospital of Chengdu University of Traditional Chinese Medicine, with the ethical approval identifier 2019 KL-029, and the institutional review boards and ethics committees of the First People's Hospital of Longquanyi District, with the ethical approval identifier AF-KY-2020071. The results of this trial will be disseminated through peer-reviewed publications and conference abstracts or posters.

The Decreasing Incidence of Acute Appendicitis During COVID-19: A Retrospective Multi-centre Study

Background

As the novel coronavirus disease 19 (COVID-19) spreads, a decrease in the number of patients with acute appendicitis (AA) has been noted in our institutions. The aim of this study was to compare the incidence and severity of AA before and during the COVID-19 pandemic.

Methods

A retrospective cohort analysis was performed between December 2019 and April 2020 in the four high-volume centres that provide health care to the municipality of Jerusalem, Israel. Two groups were created. Group A consisted of patients who presented in the 7 weeks prior to COVID-19 first being diagnosed, whilst those in the 7 weeks after were allocated to Group B. A comparison was performed between the clinicopathological features of the patients in each group as was the changing incidence of AA.

Results

A total of 378 patients were identified, 237 in Group A and 141 in Group B (62.7% vs. 37.3%). Following the onset of COVID-19, the weekly incidence of AA decreased by 40.7% (p = 0.02). There was no significant difference between the groups in terms of the length of preoperative symptoms or surgery, need for postoperative peritoneal drainage or the distribution of complicated versus uncomplicated appendicitis.

Conclusions

The significant decrease in the number of patients admitted with AA during the onset of COVID-19 possibly represents successful resolution of mild appendicitis treated symptomatically by patients at home. Further research is needed to corroborate this assumption and identify those patients who may benefit from this treatment pathway.

Revisiting Tramadol: A Multi-Modal Agent for Pain Management

Tramadol-an atypical opioid analgesic-has a unique pharmacokinetic and pharmacodynamic profile, with opioidergic, noradrenergic, and serotonergic actions. Tramadol has long been used as a well-tolerated alternative to other drugs in moderate pain because of its opioidergic and monoaminergic activities. However, cumulative evidence has been gathered over the last few years that supports other likely mechanisms and uses of tramadol in pain management. Tramadol has modulatory effects on several mediators involved in pain signaling, such as voltage-gated sodium ion channels, transient receptor potential V1 channels, glutamate receptors, α₂-adrenoceptors, adenosine receptors, and mechanisms involving substance P, calcitonin gene-related peptide, prostaglandin E₂, and proinflammatory cytokines. Tramadol also modifies the crosstalk between neuronal and non-neuronal cells in peripheral and central sites. Through these molecular effects, tramadol could modulate peripheral and central neuronal hyperexcitability. Given the broad spectrum of molecular targets, tramadol as a unimodal analgesic relieves a broad range of pain types, such as postoperative, low back, and neuropathic pain and that associated with labor, osteoarthritis, fibromyalgia, and cancer. Moreover, tramadol has anxiolytic, antidepressant, and anti-shivering activities that could improve pain management outcomes. The aim of this review was to address these issues in the context of maladaptive physiological and psychological processes that are associated with different pain types.
