Background An important complication following mastectomy is seroma formation. Quilting, in which skin flaps are sutured to the underlying muscle, is reported to reduce seroma incidence, but might induce pain and impair shoulder function. Main objective is to compare quilting with conventional wound closure, regarding seroma incidence, health care consumption, and patient discomfort. Methods In a combined prospective and retrospective study, 254 patients undergoing mastectomy and/or axillary lymph node dissection (ALND) were included. Patients received quilting sutures or conventional closure. Primary outcome was clinical significant seroma (CSS). In prospectively included patients shoulder function and analgesic use was observed. Results CSS incidence was 12.9% in the quilted versus 62.3% in the nonquilted cohort (p < 0.001). Surgical site infections were reported significantly less in the quilted cohort. Duration of hospital stay was shorter and outpatient clinic visits were less in the quilted cohort. Surgical procedure required 10 additional minutes for quilting. No significant differences were observed in postoperative shoulder function and analgesic use. Conclusion Quilting following mastectomy reduces CSS incidence. Quilting requires 10 additional minutes during surgery. It facilitates day treatment and results in less additional outpatient clinic visits culminating in reduced health care consumption. Shoulder function and pain are not affected by quilting.

Background. The rate of inpatient mastectomies remains high despite multiple studies reporting favourably on outpatient mastectomies. Outpatient mastectomies do not compromise quality of patient care and are more efficient than inpatient care. The objective of this study was to evaluate the feasibility of outpatient mastectomy. Materials and Methods. Implementation of an outpatient mastectomy program was evaluated in a retrospective study. All patients who underwent mastectomy between January 2019 and September 2021 were included. Results. 213 patients were enrolled in the study: 62.4% (n = 133) outpatient mastectomies versus 37.6% (n = 80) inpatient mastectomies. A steady rise in outpatient mastectomies was observed over time. The second quarter of 2020, coinciding with the first COVID-19 wave, showed a peak in outpatient mastectomies. The only significant barrier to outpatient mastectomy proved to be bilateral mastectomy. Unplanned return to care was observed in 27.8% of the outpatient versus 36.3% of the inpatient mastectomies ( P = 0.198 ); the reason for unplanned return of care was similar in both groups. Conclusions. Outpatient mastectomy is shown to be feasible and safe with a steady increase during the study period. A barrier to outpatient mastectomy was bilateral mastectomy. Incidence of unplanned return to care or complications did not differ significantly between the outpatient and inpatient cohorts.

BackgroundQuilting, a technique in which skin flaps are sutured to the underlying muscle, reduces seroma after mastectomy and/or axillary lymph node dissection. The aim of this study was to assess the effect of different quilting techniques on the formation of clinically significant seroma.MethodsThis was a retrospective study including patients undergoing mastectomy and/or axillary lymph node dissection. Four breast surgeons applied the quilting technique based on their own discretion. Technique 1 was performed using Stratafix in 5–7 rows placed at 2–3 cm distance. Technique 2 was performed using Vicryl 2–0 in 4–8 rows placed at 1.5–2 cm distance. Technique 3 was performed using Vicryl 0/1 in 3 rows placed at 3–4 cm distance. Technique 4 was performed using Vicryl 0 in 4–5 rows placed at 1.5 cm distance. The primary outcome was clinically significant seroma.ResultsA total of 445 patients were included. Clinically significant seroma incidence was 4.1 per cent (six of 147) for technique 1, which was significantly lower than that for the other techniques (25.0 per cent (29 of 116), 29.4 per cent (32 of 109), and 33 per cent (24 of 73) for techniques 2, 3, and 4 (P &lt; 0.001) respectively). The duration of surgery was not significantly longer for technique 1 compared with the other three techniques. The length of hospital stay, number of additional visits to the outpatient clinic, and reoperations did not differ significantly between the four techniques.ConclusionQuilting using Stratafix and placing 5–7 rows with 2–3 cm distance between the stitches associates with low clinically significant seroma incidence without adverse effects.

Background Seroma is the most common complication following breast cancer surgery, with reported incidence up to 90%. Seroma causes patient discomfort, is associated with surgical site infections (SSI), often requires treatment and increases healthcare consumption. The quilting suture technique, in which the skin flaps are sutured to the pectoralis muscle, leads to a significant reduction of seroma with a decrease in the number of aspirations and surgical site infections. However, implementation is lagging due to unknown side effects, increase in operation time and cost effectiveness. Main objective of this study is to assess the impact of large scale implementation of the quilting suture technique in patients undergoing mastectomy and/or axillary lymph node dissection (ALND). Methods The QUILT study is a stepped wedge design study performed among nine teaching hospitals in the Netherlands. The study consists of nine steps, with each step one hospital will implement the quilting suture technique. Allocation of the order of implementation will be randomization-based. Primary outcome is ‘textbook outcome’, i.e.no wound complications, no re-admission, re-operation or unscheduled visit to the outpatient clinic and no increased use of postoperative analgesics. A total of 113 patients is required based on a sample size calculation. Secondary outcomes are shoulder function, cosmetic outcome, satisfaction with thoracic wall and health care consumption. Follow-up lasts for 6 months. Discussion This will be one of the first multicentre prospective studies in which quilting without postoperative wound drain is compared with conventional wound closure. We hypothesize that quilting is a simple technique to increase textbook outcome, enhance patient comfort and reduce health care consumption.
