Brief summary
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 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. Main objective of this randomized stepped wedge study is to assess the impact of large scale implementation of the quilting technique in patients undergoing mastectomy and/or axillary lymph node dissection. This will be one of the first multicentre prospective studies in which quilting without postoperative wound drain is compared with conventional wound closure. The hypothesis is that quilting is a simple and cost-effective technique to increase textbook outcome. Moreover, it is expected that patient comfort is enhanced by quilting.
Detailed description
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 technique, in which 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). 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 use of analgesics is not increased postoperative. A total of 113 patients is required based on a sample size calculation. This will be one of the first multicentre prospective studies in which quilting without postoperative wound drain is compared with conventional wound closure. The hypothesis is that quilting is a simple technique to increase textbook outcome, without increasing health care consumption. Moreover, the expectation is that patient comfort is enhanced by quilting.
Interventions
PROCEDUREQuilting
Following mastectomy and/or axillary lymph node dissection, the subcutaneous tissue is sutured to the pectoralis muscle placing multiple rows of running sutures. The suture starts at either end of the scar, running back and forth, creating rows of quilting stiches. The rows are placed transversely from the cranial to the caudal end of the wound with 2-3 cm between them, totalling some three to five rows for the cranial flap. The caudal flap is quilted with 2-3 rows in a caudal to cranial fashion. A subcutaneous suture followed by a intracutaneous running suture is used to close the skin.
PROCEDUREConventional wound closure
Following mastectomy, skin is closed using subcutaneous sutures followed by intracutaneous running suture. Depending on the surgeons discretion a vacuum closed suction drain was placed beneath the skin flaps.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Textbook outcome | 6 months | 'Textbook outcome' (TO), a combination of outcome parameters reflecting an ideal surgical outcome. Measured 6 months post-operative, the patients postoperative course must comply with the following to meet the definition of TO: * no wound complications * no re-admissions in relation to primary surgery * no re-operation in relation to primary surgery, re-excisions in case of involved margins allowed * no unscheduled visit to the outpatient clinic (depending on the centre one or two postoperative visits are usually scheduled) * postoperative use of analgesics (6 months) is not increased compared to pre-operative |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical significant seroma | 6 months | All aspirated seroma. Severity of complicaties are scored using the Clavien Dindo Classification of Surgical complications (grade I-V). |
| Surgical site infections | 6 months | Severity of complicaties are scored using the Clavien Dindo Classification of Surgical complications (grade I-V). |
| Bleeding complications | 6 months | Severity of complicaties are scored using the Clavien Dindo Classification of Surgical complications (grade I-V). |
| Wound healing problems | 6 months | Including skin flap necrosis, wound necrosis, wound dehiscence. Severity of complicaties are scored using the Clavien Dindo Classification of Surgical complications (grade I-V). |
| Duration of surgery | 360 minutes | Duration of surgery in minutes. |
| Length of hospital stay | 6 months | Length of hospital stay in days: distinguishing between outpatient and inpatient treatment. |
| All palpation-detected seromas | 6 months | Severity of complicaties are scored using the Clavien Dindo Classification of Surgical complications (grade I-V). |
| Readmission to the hospital | 6 months | Readmission to the hospital related to primary surgery |
| Reoperation | 6 months | Reoperation related to primary surgery other than re-excision. |
| Shoulder function | 6 months | Assessed using the Disability of the Arm, Shoulder and Hand (DASH) questionnaire. Higher scores mean a worse outcome. |
| Post-operative pain | 14 days | Assessed using the visual analogue scale (VAS). Scale 1-10, higher scores mean a worse outcome. |
| Cosmetic outcome assessed by an independent panel | 6 months | an independent panel of four surgeons will blindly assess cosmetics by classifying standardised digital photographs one a 4-point Likert scale with the following categories: poor, fair, good and excellent. Photos are taken in two positions: the first in neutral position with both arms hanging next to the body and the second with both arms raised in 180gr (or as far as possible) elevation. |
| Patient reported satisfaction with breast | 6 months | BreastQ questionnaire for mastectomy |
| Unscheduled visits to the outpatient clinic | 6 months | Number of unscheduled visits to the outpatient clinic |
