Sclerotherapy for the treatment of postmastectomy seroma

BACKGROUND: Seroma is a common complication after mastectomy. We review our experience with sclerotherapy for postmastectomy seroma management. METHODS: Patients who underwent outpatient sclerotherapy for postmastectomy seroma were reviewed. Ninety-five percent ethyl alcohol or povidone iodine, which was administered by way of percutaneous catheter, was the initial sclerosant, and dwell time was 20 to 30 minutes. Povidone iodine solution was instilled 2 to 3 times daily. Catheters were removed when output reached <30 mL/d or when cavity size was <20 ml by sinogram. RESULTS: Sixteen patients (18 seromas) had sclerotherapy initiated at median of 34 days after surgery. Mean number of treatment days was 3 (median duration 16). Seven patients (44%) developed infection during treatment, which was associated with increased duration. Three seromas recurred and were successfully treated with single aspiration. COMMENTS: Sclerotherapy is a feasible treatment for chronic seroma after mastectomy. Longer treatment duration was associated with infection; antibiotic prophylaxis should be considered. Research is necessary to determine optimal regimens and superiority over other approaches.     

Postmastectomy reconstruction with extended latissimus dorsi myocutaneous flap for Hong Kong Chinese

Objective: Because of the smaller breast size of Chinese women, postmastectomy reconstruction without prosthesis by extended latissimus dorsi (LD) flap is potentially more applicable in the Chinese population. Methods: Patients who had undergone immediate postmastectomy breast reconstruction by extended latissimus dorsi flap without prosthesis were retrospectively studied. Surgical complications, aesthetic result and patient satisfaction were evaluated. Results: Ten Asian patients (nine Chinese and one Filipino) underwent extended LD flap for breast reconstruction after mastectomy. There was no total or partial flap failure. Operative complications included seroma in one patient and minor wound edge slough at back wounds in two patients. Simultaneous seroma and minor donor wound slough occurred in another patient. Aesthetic outcome was excellent (n = 5), good (n = 4) and poor (n = 1). Patient satisfaction with the procedure was very satisfied in four, satisfied in four and dissatisfied in two, respectively. All but two patients would recommend the same procedure to their friends or relatives. Conclusion: Extended LD flap can reliably achieve pleasing results with low morbidity. It has more potential to become a competitive alternative to transverse abdominis myocutaneous flap in most Chinese women for postmastectomy reconstruction.     

Randomized clinical trial of the effect of quilting latissimus dorsi flap donor site on seroma formation

BACKGROUND: Latissimus dorsi (LD) flap breast reconstruction is associated with a high incidence of donor site seromas, despite the use of surgical drains. The aim of this study was to evaluate the use of donor site quilting sutures, as well as drains, on the incidence, volume and frequency of seroma aspiration. METHODS: The trial randomized 108 women undergoing LD breast reconstruction to quilting procedures (54) or control group (52) for intention-to-treat analysis; two were excluded. Outcome measures were the incidence and volume of postoperative seroma. Secondary outcome measures included postoperative back pain, analgesic consumption, shoulder movement and duration of hospital stay. RESULTS: Quilting significantly reduced the overall incidence of seroma from 46 of 48 (96 per cent) to 43 of 52 (83 per cent) (P = 0.036), including the 38 women who had extended LD flap (with or without implants). There were further significant reductions in seroma volume (P = 0.004), frequency of aspiration (P = 0.001) and overall seroma volumes, including surgical drainage and symptomatic seromas (P = 0.013). Subset analyses for LD-implant (60 women) and extended LD (with or without implant) showed similar significance. Quilting did not affect back pain or compromise shoulder mobility. CONCLUSION: Quilting significantly reduced overall seroma volumes after LD breast reconstruction including extended LD, and is recommended in combination with surgical drains.     

Harvesting of the latissimus dorsi muscle: A small animal model for seroma formation

A common complication of soft tissue dissection and muscle harvesting is seroma formation. In order to manage and understand the formation of seromas, we developed a small animal model for seromas in the Sprague Dawley rat. Skin flaps and subcutaneous tissue were elevated and the latissimus dorsi muscle was harvested in 20 animals. Eighteen of the 20 rats (90%) formed clinically significant seromas. Sixteen animals had associated skin flap necrosis and 12 required serial drainage for recurrent seromas. At necropsy, gross capsular formation occurred in all animals who developed seromas. Microscopically, a fibrous capsule enveloping the seroma was seen associated with a focal chronic inflammatory cell infiltrate. We conclude: (1) Elevation of the latissimus dorsi muscle in the rat is a reliable and practical animal model for seroma formation; (2) Sequelae of clinically significant seromas are often as severe as skin flap necrosis; (3) An inflammatory reaction may be associated with seromas. © 1995 Wiley-Liss, Inc.     

Seroma formation after breast cancer surgery: incidence and predicting factors

The pathophysiology of seroma formation has yet to be determined. Therefore, the present study was undertaken to calculate the incidence of postoperative seromas after definitive breast cancer operations utilizing electrocautery dissection. Additionally, we attempted to identify risk factors associated with seroma development and to examine seroma formation in relation to operative procedure. A retrospective review of 252 breast cancer operations was undertaken. Patients were subdivided by operative procedure: modified radical mastectomy (MRM; n = 148), breast preservation with axillary node dissection (n = 64), or MRM with immediate reconstruction (n = 40). Electrocautery was used in development of skin flaps. Seromas developed in 39 of the 252 operations for an incidence of 15.5 per cent. Seroma formation was significantly lower in those patients receiving MRM with immediate reconstruction than in those receiving MRM (2.5% vs 19.6%; P = 0.009) and tended to be lower than for patients receiving breast preservation with axillary node dissection (14.06%; P = 0.052). Neoadjuvant chemotherapy was performed in 18 patients, of whom 6 developed seromas (P = 0.030). The incidence of postoperative seromas was low despite the use of electrocautery. An association of postoperative seromas with neoadjuvant chemotherapy was noted. Additionally, it appears that immediate reconstruction may reduce the incidence of postoperative seromas, presumably by filling the dead space in the chest wall.     

Prevention of Seroma Formation after Axillary Dissection—A Comparative Randomized Clinical Trial of Three Methods

Seroma is a frequent complication after breast cancer surgery. Closed suction drainage for several days is the standard procedure to reduce seroma formation. The aim of this study was to compare the efficacy of external compression dressing, suture flap fixation, and the conventional method of closed suction drains in the prevention of seroma formation. A total of 161 patients were prospectively randomized in a three groups × two subgroups design into control (n = 48), compression dressing (n = 53) and suturing groups (n = 49), and two subgroups, conventional drain removal (n = 75) and early drain removal (n = 75). All patients underwent ALND as part of MRM or BCT. The primary end point was the incidence of seroma. Suture flap fixation significantly reduced the incidence of seroma (p = 0.003), total drain output (p = 0.005), and duration of drainage (p = 0.001) without increase in wound complications. Compression dressing reduced duration of drainage significantly (p = 0.03), but not the total drain output (p = 0.15) or seromas (p = 0.58). Early drain removal on postoperative day 7 irrespective of drain output does not significantly increase seroma formation (p = 0.34) or wound complications. On multivariate analysis, BMI ≥ 30 (p = 0.02) and longer duration of drainage (p = 0.04) were identified as independent predictors for seroma formation. Obliteration of the dead space after breast cancer surgery by suture flap fixation is a safe and easy procedure, which significantly reduces postoperative seroma formation and duration of drainage. Compression dressing offers no advantage over normal dressing. Drains can be removed safely on postoperative day 7 irrespective of output without significant increase in complications.     

Postoperative seroma formation in breast reconstruction with latissimus dorsi flaps: a retrospective study of 174 consecutive cases

The latissimus dorsi flap has been widely used in breast reconstruction surgery. Despite its potential advantages such as low donor morbidity and vascular reliability, the complication of donor-site seroma formation frequently occurs. Consecutive 174 patients who underwent breast reconstruction with the latissimus dorsi flap from 2001 to 2006 were retrospectively reviewed. The age, body mass index (BMI), smoking history, timing of reconstruction, type of breast surgery and nodal dissection, and several other intraoperative data were analyzed. The overall incidence of postoperative seroma was 21%. Increased age (>50 years) and obesity (BMI >23 kg/m) were significant risk factors for seroma formation (P = 0.02 and 0.004, respectively). The patients who underwent skin-sparing mastectomy or modified radical mastectomy had higher incidence of seroma formation (28% and 33%, respectively) as compared with those who had breast-conservative surgery (11%). A significant correlation was found between the type of breast surgery and the incidence of seroma (P = 0.04). The type of nodal dissection did not affect the incidence of postoperative seroma (P = 0.66). We concluded that increased age, obesity, and invasive breast surgery are risk factors for donor-site seroma formation after breast reconstruction with the latissimus dorsi flap. Close attention should be paid to prevent development of postoperative seroma when operating on such high-risk patients.     

Seroma following endoscopic extraperitoneal inguinal hernioplasty

Background: Because it mimics a postoperative recurrence of hernia, seroma has been a concern to patients. There has been no consensus on the management of this condition after endoscopic totally extraperitoneal inguinal hernioplasty (TEP). The objectives of the present study were to evaluate the incidence and treatment of seroma after TEP. Risk factors for the development of seroma were also examined. Methods: A total of 450 consecutive patients who underwent TEP between June 1999 and May 2002 were recruited. All data were collected prospectively. The outcomes of patients who developed seromas were compared to those without this postoperative complication. Regression analysis was performed to identify independent risk factors for seroma formation. Results: The overall incidence of seroma formation was 7.2% (n = 40). The postoperative recovery of patients was not influenced by the development of seroma. The mean size of the seromas was 3.8 cm. Adopted treatment strategies included observation (n = 29), oral lysozyme (n = 10), and percutaneous aspiration (n = 3), but neither of the two interventions appeared to be effective. The seromas resolved spontaneously by an average of 2.4 (mean) months. Significant clinical factors associated with seroma formation included old age, large hernial defects, an extension of the hernia into the scrotum, and the presence of a residual distal indirect sac. By logistic regression, a large hernial defect and an extension of the hernia into the scrotum were found to be independent risk factors for seroma formation. Conclusions: Although seroma is a frequent minor morbidity after TEP, it has no impact on postoperative recovery. Because all seromas invariably resolve, expectant treatment with observation is recommended. Inguinoscrotal hernia carries a four-fold increased risk of developing seroma after TEP.

Seroma in ventral incisional herniorrhaphy: incidence, predictors and outcome

Background

Factors leading to seroma following ventral incisional herniorrhaphy (VIH) are poorly understood.

Methods

Between 2004 and 2006, patients were prospectively randomized at 4 Veterans Affairs hospitals to undergo laparoscopic or open VIH. Patients who developed seromas within 8 weeks postoperatively were compared with those who did not. Multivariate analyses were performed to identify predictors of seroma.

Results

Of 145 patients who underwent VIH, 24 (16.6%) developed seromas. Patients who underwent open VIH had more seromas than those who underwent laparoscopic VIH (23.3% vs 6.8%, P = .011). Seroma patients had hernias that were never spontaneously reducible (0% vs 21%, P = .015), had more abdominal incisions preoperatively (mean, 2.4 vs 1.8; P = .037), and were less likely to have drain catheters placed than those without seromas (30.0% vs 63.1%, P = .011). In multivariate analyses, open VIH predicted seroma (odds ratio, 5.5; 95% confidence interval, 1.6-18.8), as well as the specific hospital at which the procedure was performed. Spontaneous resolution occurred in 71% of seromas; 29% required aspiration.

Conclusions

Procedural characteristics and hernia characteristics rather than patient comorbidities predicted seroma in VIH.     

Seroma prevention using fibrin glue during modified radical neck dissection in a rat model

Seroma is a frequent sequelae of neck dissection involving cervical lymphadenectomy. The incidence is correlated with flap elevation, lymphovascular interruption, and tissue removal. Current methods of resolving seroma, such as vacuum drainage, are not risk free. A novel approach to this problem was the use of intraoperative topical fibrin glue. A model producing seromas was developed by modified radical neck dissection on Sprague-Dawley rats. Forty rats underwent this procedure. Twenty rats were treated with saline solution (control group) and 20 were treated with fibrin glue. At necropsy on day 5, a significant reduction in the frequency of seroma was noted in the fibrin glue group. Seventeen of 20 control rats had seroma whereas only 2 of 20 experimental animals had serous collection. The Fisher exact statistical correlation revealed p less than 0.000002; therefore, the use of fibrin glue in this role merits further evaluation.     

Effect of fibrin glue on lymphatic drainage and on drain removal time after modified radical mastectomy: a prospective randomized study

Seroma formation is a frequently occurring complication in patients operated on because of breast cancer. This complication can be the cause of flap necrosis, can lead to infection, and can prolong the hospital stay. It can also cause a delay in chemotherapy and radiotherapy. In order to prevent seroma formation, various methods such as external compression dressings, immobilization of the arm, sclerotherapy, and suction drainage have been used, without much success. In animal models and some clinical studies, it has been stated that fibrin glue reduces seroma formation, and these statements generated high expectations. For this reason, a prospective study was planned to test this in patients who underwent modified radical mastectomy (MRM) because of breast cancer. Of the 54 patients studied, 27 patients had fibrin glue (4 ml) applied to wound surfaces and under the flap (study group); the remaining 27 patients were the control group. Daily drainage volumes, total amount of drainage, drain removal time, and seroma formation were recorded and compared between the two groups. The first-day drainage was significantly lower in the study group (p<0.05, Student's t-test). There were no significant differences in daily drainage volumes, drain removal time, seroma formation frequency, and the number of seromas between the two groups (p>0.05). In conclusion; fibrin glue application had no significant benefit on axillary lymphatic drainage, drain removal time, or seroma formation.     

Early removal of postmastectomy drains is not beneficial: results from a halted randomized controlled trial

BACKGROUND: Closed-suction drainage to reduce seromas is standard after mastectomy. This study evaluates the safety of early drain removal. METHODS: Women undergoing mastectomy were randomized to early removal on postoperative day 2 or standard removal (< 30 mL drainage in 24 hours or postoperative day 14). Primary endpoints were time to drain removal and physician visits. Secondary endpoints were number of seroma aspirations, drain reinsertions, and infections. RESULTS: Twenty-seven patients were recruited before an interim analysis was performed to address safety concerns. Three patients withdrew before trial completion, leaving 14 patients in the standard group and 10 in the early group. Patients in the standard group had significantly fewer seroma aspirations, fewer drain reinsertions, and fewer physician visits. The trial was halted because of the higher rate of events in the early group. CONCLUSION: Surgical drains cannot be safely removed on postoperative day 2 after mastectomy. Early removal significantly increases the occurrence of seromas requiring treatment.     

Laparoscopic repair of direct inguinal hernia: a new technique that reduces the development of postoperative seroma

Background Seroma are common early postoperative complications encountered in laparoscopic inguinal hernia repair. Previous anecdotal evidence from our surgical practice suggested a lower incidence of postoperative seroma formation with direct hernia repairs when the lax transversalis fascia (TF) is inverted by tacking to the pubic ramus. We undertook a study to investigate whether TF inversion in this way reduces the incidence of postoperative seroma. Method A total of 216 patients undergoing transabdominal preperitoneal (TAPP) laparoscopic inguinal hernia repairs from August 2003 to December 2005 were included in this prospective non-randomised controlled study. Surgeon 1 would routinely invert the TF whereas surgeon 2 would not. At follow-up the presence of postoperative seroma and pain was recorded. Results Mann–Whitney U test demonstrated no significant difference in terms of age, sex and time to follow-up between the surgeons’ patient groups (P > 0.05), and Chi-square test demonstrated significantly that inversion of the TF is associated with a lower incidence of postoperative seroma (P < 0.05). There was no significant difference in terms of postoperative pain at follow-up. Conclusion Inversion of the TF is associated with a statistically lower incidence of postoperative seroma, without increasing postoperative pain despite the use of one or two additional tacks.     

Risk factors for donor-site seroma formation after immediate breast reconstruction with the extended latissimus dorsi flap: a statistical analysis of 120 consecutive cases

The extended latissimus dorsi flap has been widely used for breast reconstruction. However, seroma at the donor site is a common complication and makes it difficult for reconstructive surgeons to choose it as a primary option. We analyzed the association between seroma and reconstructions with extended latissimus dorsi flaps. A series of 120 consecutive cases were included in this study. The average body mass index (BMI) was 22.1 kg/m, and the mean ratio of the flap weight to the extirpated breast weight was equivalent to 101.6%. The mean age of patients was 40.3 years. Donor-site seroma was reported in 69.2% (83 cases) of the total patients. With respect to BMI, flap weight, and age, the incidence and duration of donor-site seroma showed statistically significant differences (P<0.05). Both the incidence and duration of seroma were significantly higher and longer in patients who had high BMI (>23 kg/m), large flap (>450 g) for reconstructions, or advanced age (>45 y). In these cases, greater attention and additional adjunctive procedures would be needed to prevent seroma.     

Postoperative seroma formation after abdominoplasty with placement of continuous infusion local anesthetic pain pump

The most common complication after abdominoplasty is seroma formation. The incidence of seroma formation in abdominal procedures as a whole, including abdominoplasty, panniculectomy and transverse rectus abdominis myocutaneous flap abdominal donor sites, ranges from 1% to 38%. A recent concern among surgeons is the possibility of a causal relationship between the use of continuous infusion devices such as local anesthetic pain pumps and the development of seromas. A case of postoperative, persistent, recurrent seroma formation after abdominoplasty with the use of continuous infusion local anesthetic pain pump is presented. After several attempts at aspiration and drain catheter placement, only open surgical excision of the seroma cavity was found to be definitively effective in treating the development of seroma.     

腹腔镜经腹腹膜前疝修补术中斜疝疝囊横断术与剥离术对其术后并发症的影响

目的比较腹腔镜腹股沟疝修补术中斜疝疝囊横断与完全剥离对手术并发症的影响。 方法回顾性分析2016年1月至2020年6月于江苏省人民医院溧阳分院行腹腔镜经腹腹膜前疝修补术（TAPP）166例男性单侧腹股沟斜疝的病例资料。根据手术方式，分为疝囊横断组（86例）与完整剥离组（80例）。比较2组患者的术后疼痛、复发及血清肿等指标。 结果2组之间的术后急性、慢性疼痛差异无统计学意义（P>0.05）。疝囊离断组术后2 d和7 d的血清肿发生率（18.6%和27.8%）高于疝囊完整剥离组（7.5%和15.0%），差异有统计学意义（P<0.05）。术后3个月，血清肿自行消失。术后随访6~36个月所有患者均未复发。 结论TAPP术中，疝囊完整剥离与疝囊横断术疗效相当，医师可根据患者的术中情况选择横断或者剥离。尽管疝囊横断术后血清肿会增加，但是在3个月内会自愈。     

Incidence and management of seroma after arteriovenous graft placement

BACKGROUND: Perigraft seromas are rare complications of insertion of PTFE hemodialysis grafts. They are often difficult to treat and recurrence is common. This study evaluates the incidence, potential etiologic variables, and management strategies for seromas after prosthetic arteriovenous graft (AVG) placement. STUDY DESIGN: A retrospective analysis of all patients undergoing AVG placement between August 2002 and December 2005 was performed to identify all patients diagnosed with seroma requiring surgical intervention. Multiple variables were analyzed to determine potential risk factors for seroma formation and outcomes of various forms of surgical management. RESULTS: In this interval, 535 AVG were inserted in 427 patients. Ten patients presented with a seroma and underwent surgical treatment. Overall incidence of seroma formation was 1.7%. There was no significant difference in seroma formation based on gender, age, diabetes, lower extremity versus upper extremity placement, or loop forearm versus straight forearm grafts. A statistically significant difference was found between upper arm (p = 0.007) and lower arm grafts (p = 0.04), with upper arm grafts more prone to seroma formation. Patients undergoing bypass of the seromatous segment of graft have not had a recurrence, compared with those who were simply evacuated and have had a mean patency of 402 days. CONCLUSIONS: Seroma complications after AVG insertion are higher in patients with upper arm grafts. To minimize this complication, meticulous operative technique is required. If a seroma develops, the graft might still be salvageable with aggressive management, including bypass of the involved segment.

Seroma formation after axillary lymphadenectomy with and without the use of drains

Seroma formation after axillary lymphadenectomy is common. We performed a randomised controlled trial comparing seroma rate and volume after axillary lymphadenectomy with and without use of drains. In this study, there was no difference in incidence of seroma formation between patients who did and did not have a drain inserted after axillary lymphadenectomy for breast cancer. Undrained patients, however, had larger volume seromas of longer duration which required more aspirations. There was a tendency for undrained patients to have fewer complications when compared to patients with drains.     

Seroma prevention by using Corynebacterium parvum in a rat mastectomy model

Seroma formation is the most common complication after mastectomy and continues to be an important problem during the early postoperative period. Several surgical and medical methods have been developed to try to overcome this problem; however, so far none have been used successfully in the routine clinical practice. The aim of this study is to evaluate the effects of Corynebacterium parvum (CP) as a sclerosing agent in both prevention and treatment of seromas after mastectomy and axillary dissection in an animal model. Sixty female Sprague-Dawley rats underwent mastectomy and axillary dissection under general anaesthesia. Following surgery, the rats were treated in 1 of 3 ways. In the prevention group, 1 cm3 (0.35 mg) CP solution was injected beneath the skin flap just before closure of the incision after mastectomy. In the treatment group, animals in which a seroma was formed, the fluid was aspirated, and 1 cm3 CP solution was injected beneath the flap. In the control group, animals in which seromas formed, aspiration only was performed. The frequency of seroma formation decreased when CP solution was injected immediately after the operation (p < 0.01). In addition, seroma formation was effectively treated by CP injection when compared with the control group (p < 0.05). CP was effective as a prophylactic agent in the prevention group and as a therapeutic agent in the treatment group in this experimental model. CP injection may be useful for the management of this problem in a clinical setting.
