Safety of Drainless Donor Closure in DIEP Flap-Based Breast Reconstruction: A Prospective Analysis Using Ultrasound

Perceptions of Surgical Drains among Breast Reconstruction Patients and Health Care Staff: A Qualitative Survey Study

BACKGROUND

 Surgical drains are a key component for recovery in breast reconstruction procedures. However, they are often cumbersome and carry a risk of infection with prolonged use. We aimed to develop a more thorough understanding of patient and health care provider perspectives on surgical drains, to inform future efforts in improving the breast reconstruction patient experience.

METHODS

 Twenty-nine breast reconstruction patients and eight plastic surgery providers were recruited to complete surveys focused on surgical drains. Likert scales ranging from 1 to 5 were developed to gauge how bothersome drains felt, as well as concern for infection. Ordinal variable and categorical multiple-choice analyses were applied as appropriate.

RESULTS

 Fifteen (51.7%) patients underwent implant-based breast reconstruction, and 14 (48.3%) patients underwent autologous breast reconstruction. The most common duration of drain placement was 2 weeks (N = 13). The surgical site infection (SSI) rate requiring antibiotics was 28% (N = 8). On a scale of 1 to 5, both patients (median = 3) and providers (median = 2.5) viewed drains as bothersome. Patients were "frequently" concerned about infection risk (median = 3). Other high-frequency patient concerns included general pain and discomfort.

CONCLUSION

 Surgical drains are a common component of breast reconstruction procedures and are viewed as cumbersome by both patients and providers. Patients expressed concerns about drain site pain, discomfort, and tugging on clothing. Patients and providers both believed that drains could contribute to SSI. Overall, these data provide insight to drive future improvements in the patient drain experience.

Risk Factors for Step-Off Deformity of the Donor Site following Abdominal Flap-Based Breast Reconstruction

BACKGROUND

Step-off deformity is a suboptimal aesthetic outcome at the donor site following abdominal flap harvesting for breast reconstruction. This study assessed the prevalence of step-off deformities after autologous breast reconstruction and explored the associated risk factors.

METHODS

This retrospective study evaluated step-off deformities among consecutive patients who had undergone autologous abdominal flap-based breast reconstruction between January of 2019 and December of 2022. The postoperative evaluation used medical records and photographs, defining step-off deformity as a thickness discrepancy in the upper and lower abdominal tissue with reference to the scar line and angles less than 165 degrees. Moreover, the study explored potential risk factors, including abdominal subcutaneous tissue thickness based on computed tomography.

RESULTS

In total, 187 patients underwent abdominal flap-based breast reconstruction; 38 exhibited step-off deformity. The case group exhibited significantly higher body mass index (BMI) and greater subcutaneous layer thickness in both the upper and lower abdomen compared with those of the control group. The groups did not differ significantly in postoperative complications, including abdominal bulging or hernia. Multivariable analysis revealed notable risk factors for step-off deformity development: BMI ( P = 0.026), presence of preoperative abdominal fold ( P = 0.028), and thickness differences between the upper and lower abdomen ( P = 0.011). The cut-off values were 26.1 kg/m 2 for BMI and 9.5 mm for thickness differences.

CONCLUSIONS

Higher BMI, presence of abdominal fold, and significant upper-lower abdomen tissue thickness differences may be associated with an increased risk of donor step-off deformity after abdominal flap harvest. These findings may inform patient counseling and warrant attention when closing donor wounds in high-risk individuals.

Evaluating Donor Morbidity in ALT and TDAP Flaps With Drainless Closure Compared to Conventional Drain Placement

PURPOSE

Recent trends in reconstructive surgery focus on rapid recovery, questioning the necessity of postoperative drains. Although harvesting perforator flaps causes minimal injury to anatomical structures at donor sites, attempts to omit drains have been limited. This study aimed to assess the safety of not using drains after harvesting the anterolateral thigh (ALT) perforators and the thoracodorsal artery perforator (TDAP) flaps.

METHODS

All consecutive patients who underwent free ALT or TDAP flap-based reconstruction between 2020 and 2022 did not have drains placed at the donor site. Their donor morbidities were evaluated, and compared with those who underwent the same operation between 2016 and 2019 with donor drains placed.

RESULTS

The drainless cohort consisting of 202 cases (159 ALT and 43 TDAP flaps) and the control cohort comprising 119 (52 ALT and 67 TDAP flaps) were analyzed. In ALT flap cases, the drainless cohort, apart from a larger flap dimension, exhibited comparable baseline characteristics to the control. The rates of overall donor complications were comparable between the two cohorts (10.1% vs. 11.5%, p = 0.795), as were rates for specific complications including wound dehiscence (p = 0.751) and seroma (p = 0.999). Multivariable analysis revealed no significant association between omitting drains and increased donor complications. Consistent results were obtained in the analysis for cases using TDAP flaps, with no significant difference between drainless and drain-using groups (p = 0.297).

CONCLUSIONS

Omitting drains in the donor site of ALT and TDAP flaps might be safe, not escalading the risks of donor morbidity.

DIEP Donor Site Satisfaction between Patients with and without History of Pregnancy

BACKGROUND

 With the success of free autologous breast reconstruction, the abdominal donor site is now an important consideration, especially in patients of childbearing age. In our institution, there are increasing patients who have successfully undergone the deep inferior epigastric artery perforator (DIEP) flap despite previous pregnancy. This study aims to answer questions on the effect of the donor site on pregnancy and vice versa.

METHODS

 A retrospective cohort study was conducted to identify breast cancer patients who received a free DIEP flap for breast reconstruction from January 2018 to August 2020. Patients were allocated to two groups according to whether they had prior pregnancies with successful deliveries. Demographics, flap-related parameters, surgical outcomes on breast and abdomen, and patient-reported outcome (Breast-Q questionnaire) were analyzed. Patients were excluded if follow-up time was less than 1 year, or if there was incomplete medical records or Breast-Q replies.

RESULTS

 Ninety-nine of 116 patients had had successful pregnancies with delivery, 17 of them remained nulliparous. No statistically significant differences existed between groups regarding demographic data, flap-related parameters, surgical outcomes on breast and abdomen. Nulliparous patients exhibited significantly lower score in physical well-being in the abdomen domain compared with delivery-experienced patients (62.1 vs. 73.4, p = 0.025). Significantly, nulliparous patients felt more tightness and pulling of the abdominal wall than the delivery-experienced patients (2.9 vs. 3.7; p = 0.05 and 3.5 vs. 4.0; p = 0.04).

CONCLUSION

 Free DIEP flap can be transferred safely in nulliparous patients despite a slight increase in abdominal tightness and abdominal pulling. Precise flap design and surgical approaches may help to minimize the abdominal discomfort especially on young, normal body mass index, and nonchildbearing patients.

Shifting toward total drainless approach in DIEP flap-based breast reconstruction: Evaluation of safety

With increasing interest in swift postoperative recovery, there has been a trend toward omitting drains in deep inferior epigastric perforator (DIEP) flap-based breast reconstruction, ideally aiming to avoid drains in the breasts and abdomen. This study evaluated our transition toward total drainless reconstruction, focusing specifically on the safety of omitting drains in the breasts. Patients who underwent breast reconstruction with DIEP flap from 2018 to 2023 were reviewed. They were divided into 3 groups: group A (with drains in the abdomen and breast), group B (drains only in the breast), and group C (total drainless). For group C, routine ultrasound examinations were performed to check for fluid accumulation. Complication profiles were compared among the groups. In total, 294 cases were included, comprising 77 in group A, 112 in group B, and 105 in group C. Chronologically, a gradual increase in the proportion of cases in group C was observed, with the complication rates remaining stable. On comparing the complication profiles of the recipient and donor sites among the 3 groups, no significant differences were found. Breast seroma, persisting 1 month postoperatively, was exclusively detected in 6 (5.7%) cases within group C, all of whom were treated with outpatient clinic-based aspiration. When restricting the analysis to group C, a greater weight of mastectomy specimen and axillary lymph node dissections exhibited an independent association with breast seroma development. Smooth transition to total drainless DIEP breast reconstruction appears safe, without significantly increasing the risks of complication.
