Abcès du sein lactant : et si on ne les opérait plus ?

Maintaining Breastfeeding During the Treatment of Breast Abscesses Is Not Contraindicated

Background: World Health Organization guidelines recommend maintaining breastfeeding if a woman develops breast abscess, because of benefits to her recovery and the infant's health. However, clinical staff recommend weaning to promote faster recovery from the abscess. The purpose of this study was to determine whether maintaining breastfeeding after development of a breast abscess has any influence on the resolution of the breast abscess. Methods: The records of 212 patients who were breastfeeding and developed breast abscess treated at Guangzhou Women and Children's Medical Center from January 2018 to December 2019 were retrospectively reviewed. Patients were divided into two groups: those who maintained breastfeeding (study group) and those who stopped breastfeeding (control group). Results: There were 139 patients in study group and 73 patients in the control group. Baseline characteristics were similar between the two groups. The time to cure in the study group and in the control group was 7.20 ± 2.21 days and 7.01 ± 2.39 days, respectively (t = 0.579, p = 0.563). Common complications were milk fistula and galactocele, and the frequency of both was similar between the two groups (milk fistula: 7.9% versus 8.2%, respectively; χ² = 0.006, p = 0.938; galactocele: 8.6% versus 9.6%, respectively; χ² = 0.054, p = 0.817). There was no significant difference in the recurrence rates between the two groups (5.0% versus 2.7%; χ² = 0.184, p = 0.668). Conclusion: Maintaining breastfeeding during treatment of breast abscess does not affect the outcome of treatment provided, on condition that the abscess is treated appropriately.

Management of lactating breast abscesses by ultrasound-guided needle aspiration and continuation of breastfeeding: A pilot study

INTRODUCTION

Needle aspiration of breast abscesses during lactation are currently recommended as an alternative to surgery only for moderate forms. In case of breast abscess, many patients stop breastfeeding on the advice of a health professional. We reviewed our experience of treatment of lactating breast abscesses by ultrasound-guided aspiration and suggest an algorithm of their management. We also analyzed the continuation of breastfeeding of these patients after advices from trained teams.

MATERIEL AND METHODS

We conducted a retrospective study from April 2016 to April 2017, including 28 patients referred for a breast abscess during lactation at the Duroc Breast Imaging Center. A management by ultrasound-guided aspiration was proposed to each patient. We collected data about the breastfeeding between October 2018 and January 2019.

RESULTS

A single aspiration was sufficient in 64.3% of cases. The delay between the occurrence of the abscess and the indication for drainage was significantly higher for patients who have needed finally surgical drainage (p = 0,0031). There were no difference of size of abscesses between patients receiving needle aspiration alone and those who have undergone surgery (p = 0,97). All patients who had been managed by needle aspiration continued breastfeeding after the treatment and 40% of the patients were still breastfeeding at 6 months.

CONCLUSION

The management of lactating breast abscess by ultrasound-guided needle aspiration is an effective alternative to surgery. It appears to be effective regardless of the size of the abscess and is compatible with the continuation of breastfeeding. Our study has indeed shown that if they are well advised, the majority of patients continue breastfeeding so that it is essential that health professionals be better trained regarding the management of breastfeeding complications.

Mastitis and More: A Pictorial Review of the Red, Swollen, and Painful Breast

Clinically, acute mastitis presents as a red, swollen, and painful breast. Targeted ultrasound can be performed to evaluate the extent of infection and for an underlying abscess. Noncomplicated mastitis or a small fluid collection may respond to oral antibiotics without further intervention, but a larger or more complex abscess may require single or serial percutaneous aspiration. Breast infections, particularly those complicated by an abscess, can have a prolonged clinical course, and close follow-up is required. Since the clinical presentation and imaging features of acute infectious mastitis can overlap with other etiologies, such as inflammatory breast cancer and idiopathic granulomatous mastitis, a percutaneous biopsy may be indicated to accurately diagnose patients.

Les abcès du sein sont des collections purulentes néoformées au niveau de la glande mammaire et du tissu péri glandulaire. Ils peuvent être lactants ou non lactants. L’objectif de notre étude était de décrire leurs caractéristiques épidémiologiques, diagnostiques et thérapeutiques au Service de Chirurgie Générale de l’Hôpital Principal de Dakar. Nous avions réalisé une étude rétrospective, descriptive sur une période de 4 ans portant sur tous les patients pris en charge pour un abcès du sein. Nous avions colligé 41 dossiers de patients tous de sexe féminin. L’âge moyen était de 31 ans. Le principal facteur de risque objectivé était la mastite au cours de l’allaitement (27%). Le délai moyen d’évolution était de 12 jours avec des extrêmes de 1 et 30 jours. L’abcès siégeait à gauche dans 61% des cas et se présentait le plus souvent sous la forme d’une tuméfaction inflammatoire (88%). Les quadrants supérieurs étaient le plus souvent concernés (43,9%). L’échographie mammaire était réalisée chez 51,2% des patientes. Le drainage chirurgical sous anesthésie générale était réalisé chez toutes les patientes. La quantité moyenne de pus était de 119 cc. Le germe le plus fréquemment isolé était le Staphylococcus aureus (79,5%). La durée moyenne d’hospitalisation était de 7 jours et la morbidité opératoire de 31,7%. La mortalité était nulle. La prévention des abcès lactants passe par l’enseignement des méthodes d’allaitement et l’antibiothérapie précoce en cas de mastite.

The estimated incidence of lactational breast abscess and description of its management by percutaneous aspiration at the Douala General Hospital, Cameroon

Background

Lactational breast abscesses are uncommon in the puerperium but when they do develop, delays in specialist referral may occur especially in resource low settings. There is a dearth of studies regarding lactational breast abscesses in Cameroon. We aimed to estimate the incidence of lactational breast abscess and describe its management by percutaneous aspiration at the Douala General Hospital, Cameroon.

Methods

We conducted an observational prospective study of 25 breastfeeding women at the Douala General Hospital from January 1, 2015, to October 31, 2015. Participants were consenting breastfeeding women who completed a baseline questionnaire after diagnosis of lactational breast abscesses and underwent percutaneous needle aspiration under local anaesthesia. Data were analyzed by using descriptive statistics.

Results

The estimated incidence of lactational breast abscesses was 0.74% (28/3792). The age range of babies at the onset of breast abscess was 4 to 35 weeks; mean 28.3 ± 10.85 weeks. Forty-four per cent of participants underwent three lactational abscess aspirations and in 24 to 28% of them, it took 8 to 9 days for the abscess to resolve. In 72% of participants, treatment was with needle aspiration plus flucloxacillin. Seventy-six per cent of participants continued breastfeeding after abscess treatment.

Conclusion

The estimated incidence of lactational breast abscess at the Douala General Hospital is 0.74%. Percutaneous needle aspiration under local anaesthesia is an effective treatment for superficial lactational breast abscesses in most cases with or without ultrasound guidance and should be recommended worldwide as first line treatment. Further research is needed to understand the outcome of local infiltration of antibiotics on the abscess cavity.

Breast infections - Microbiology and treatment in an era of antibiotic resistance

INTRODUCTION

Primary breast abscesses occur in <1% of non-lactating women, rising to 11% in women with lactational mastitis. In patients undergoing breast cancer surgery, the inflammatory response to post-operative surgical site infection (SSI) has been implicated in recurrence. Anti-microbial resistance increasingly hampers treatment in each group.

AIMS

Describe the demographic and predisposing characteristics of patients with primary breast abscesses and secondary infections, identify the microbial and antimicrobial patterns and formulate an evidence-based protocol for treating breast infections.

METHODS

Retrospective cohort study of all breast infections (primary and post-operative) treated at UHL from 2014 to 2017. Data collected from microbiology databases and patient records was analysed using Minitab V18.

RESULTS

537 cultures from 108 patients were analysed. 47 (43.5%) had primary abscesses, 12 (11.1%) were lactational and 49 (45.4%) were post-operative SSI. For primary infections, the mean age was 41.9 (±12.2) and reinfection rate 33%. For SSIs the mean age was 51.8 (±14.52) and reinfection rate 11.8%. Overall, 29.3% were smokers, 6.4% diabetic and 2.9% pregnant. 60 (43%) patients required radiological drainage and 2 (1%) surgical drainage. 57.5% had mixed growth. The most common isolate was Staphylococcus aureus; cultured in 16.7% of primary abscesses and 24% of SSIs. 13 empiric antibiotic regimes were prescribed before 26.4% of patients changed to 12 different targeted regimes.

CONCLUSION

Breast infections are frequently polymicrobial with a wide variety of organisms isolated, suggesting the need for broad spectrum coverage until culture results become available. Based on our local culture results, the addition of clindamycin to flucloxacillin would provide excellent empiric coverage for all categories of breast infection. An evidence-based treatment guideline is required and should be formulated in close collaboration with microbiology specialists.
