ABSTRACT
Purpose@#Despite the increasing use of immediate breast reconstruction (IBR), its oncologic safety in the setting of neoadjuvant chemotherapy (NACT) needs to be comprehensively clarified in breast cancer management. The objective of the present study was to analyze the oncologic safety of IBR following NACT. @*Methods@#In total, 587 patients with breast cancer who underwent a total mastectomy (TM) with IBR after NACT between 2008 and 2017 at a single institution were retrospectively reviewed. The reviewed patients with IBR following skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM) were matched 1:3 to patients who underwent TM alone after NACT. Matching variables included age, clinical T and N stages before NACT, response to NACT, pathologic T and N stages, and molecular subtypes. @*Results@#After propensity score matching, 95 patients who underwent IBR following SSM/ NSM after NACT (IBR group) and 228 patients who underwent TM alone after NACT (TM group) were selected. The median follow-up period was 73 (range, 5–181) months after matching. After matching, there were no significant differences between the two groups in 5-year locoregional recurrence-free survival (88.8% vs. 91.2%, p = 0.516), disease-free survival (67.3% vs. 76.6%, p = 0.099), distant metastasis-free survival (71.9% vs. 81.9%, p = 0.057), or overall survival (84.1% vs. 91.5, p = 0.061) rates. In multivariate analyses, conducting IBR was not associated with increased risks for locoregional recurrence, any recurrence, distant metastasis, or overall death. @*Conclusion@#Our findings suggest that IBR following SSM/NSM elicits comparable long-term oncologic outcomes to those of TM alone in the setting of NACT.
ABSTRACT
Purpose@#In this study, we examined the impact of reconstruction using tissue expander insertion (TEI) on the risk of radiation dermatitis in patients undergoing postmastectomy radiotherapy (PMRT). @*Methods@#Between August 2015 and March 2019, patients with breast cancer who had received systemic chemotherapy and PMRT were prospectively included. Skin parameters, including melanin, erythema, hydration, sebum, and elasticity, were measured using a multiprobe instrument at 6 time points: before the initiation of radiotherapy (pre-RT), at weeks 1, 3, and 5 during radiotherapy (weeks 1–5), and 1 and 3-month after radiotherapy (post-RT-1m and post-RT-3m). Patient-reported outcomes (PROs) were assessed at each time point.Changes in biophysical parameters and PRO were compared between patients with and without TEI (TEI+ vs. TEI−). @*Results@#Thirty-eight patients, including 18 with TEI+ and 20 with TEI-, were analyzed. The pattern of time-course changes in biophysical parameters and PRO did not differ between TEI+ and TEI− patients. The melanin index was highest at post-RT-1m, while the erythema index was highest at week 5. At post-RT-3m, TEI+ patients presented higher melanin values than TEI- patients, with no statistical significance (coefficient, 47.9 vs. 14.2%; p = 0.07). In all patients, water content decreased throughout the measurement period. At post-RT-3m, TEI+ patients demonstrated a further decrease in water content, while the TEI- group nearly recovered the water content to pre-RT status (coefficient, −17.1, −2.5; p = 0.11). The sebum and elasticity levels were not altered by TEI. @*Conclusion@#In patients undergoing PMRT, TEI did not significantly affect the changing patterns of skin biophysical parameters and PRO during radiotherapy.
ABSTRACT
Background@#Since April 2015, the Korean National Health Insurance (NHI) has reimbursed breast cancer patients, approximately 50% of the cost of the breast reconstruction (BR) procedure. We aimed to investigate NHI reimbursement policy influence on the rate of immediate BR (IBR) following total mastectomy (TM). @*Methods@#We retrospectively analyzed breast cancer data between April 2011 and June 2016. We divided patients who underwent IBR following TM for primary breast cancer into “uninsured” and “insured” groups using their NHI statuses at the time of surgery. Univariate analyses determined the insurance influence on the decision to undergo IBR. @*Results@#Of 2,897 breast cancer patients, fewer uninsured patients (n = 625) underwent IBR compared with those insured (n = 325) (30.0% vs. 39.8%, P < 0.001). Uninsured patients were younger than those insured (median age [range], 43 [38–48] vs. 45 [40–50] years; P < 0.001).Pathologic breast cancer stage did not differ between the groups (P = 0.383). More insured patients underwent neoadjuvant chemotherapy (P = 0.011), adjuvant radiotherapy (P < 0.001), and IBR with tissue expander insertion (P = 0.005) compared with those uninsured. @*Conclusion@#IBR rate in patients undergoing TM increased after NHI reimbursement.
ABSTRACT
Background@#Reconstruction of congenital microtia remains challenging, particularly in patients with a history of ear canaloplasty due to insufficient regional soft tissue. The insertion of a tissue expander prior to implantation of the cartilage framework has traditionally been employed. However, this procedure could induce additional morbidity. Herein, we present a method using V-Y advancement of a temporal triangular flap to gain additional soft tissue in these challenging cases. @*Methods@#Congenital microtia patients with a history of ear canaloplasty who underwent auricular reconstruction using the Nagata technique between 2016 and 2020 were reviewed. To obtain additional soft tissue, V-Y advancement of a temporal triangular flap was performed concurrently with implantation of the costal cartilage framework, without prior insertion of a tissue expander. The outcomes of these patients with respect to postoperative complications and esthetics were evaluated. @*Results@#Eight patients with bilateral lesions were included. No specific complications developed after the first-stage surgery. However, one patient experienced complications after the second stage (auricular elevation). An analysis of the esthetic results showed most patients had excellent outcomes, achieving a satisfactory convolution. The median number of operations needed to complete reconstruction was 2, which was fewer than required using the conventional method with prior insertion of a tissue expander. @*Conclusions@#In patients with a history of previous canaloplasty, V-Y advancement of a temporal triangular flap could serve as an alternative to tissue expansion for microtia reconstruction. This technique provided reliable and satisfactory results with a reduced number of surgical stages.

ABSTRACT
Although the success rate of deep inferior epigastric perforator (DIEP) flaps has increased, late flap failures still occur and have a low salvage rate. The present article describes a case of salvage of a case of late flap failure using the pedicle vein as a vein graft source. A 50-year-old woman underwent a bilateral DIEP free flap procedure. On postoperative day 6, she experienced flap compromise and underwent emergency flap revision. In the flap revision, flap venous drainage and the superficial inferior epigastric vein were completely obstructed. A Fogarty catheter was used to remove a thrombus from the completely obstructed pedicle vein, and this pedicle vein was used as a graft source and was ligated in retrograde fashion to the flap vein stump. After injection of urokinase into the arterial branch, venous flow to the flap was restored. At a 6-month follow-up visit in the outpatient clinic, only partial fat necrosis at the flap was noted. By dissecting various perforators in the initial operation, decisions regarding immediate revision can be made with more confidence. Additionally, the combined procedures performed in this case may be helpful even for practitioners treating cases of late flap compromise.
ABSTRACT
BACKGROUND: Nonliving chickens are commonly used as a microvascular anastomosis training model. However, previous studies have investigated only a few types of vessel, and no study has compared the characteristics of the various vessels. The present study evaluated the anatomic characteristics of various chicken vessels as a training model. METHODS: Eight vessels—the brachial artery, basilic vein, radial artery, ulnar artery, ischiatic artery and vein, cranial tibial artery, and common dorsal metatarsal artery—were evaluated in 26 fresh chickens and 30 chicken feet for external diameter (ED) and thicknesses of the tunica adventitia and media. The dissection time from skin incision to application of vessel clamps was also measured. RESULTS: The EDs of the vessels varied. The ischiatic vein had the largest ED of 2.69±0.33 mm, followed by the basilic vein (1.88±0.36 mm), ischiatic artery (1.68±0.24 mm), common dorsal metatarsal artery (1.23±0.23 mm), cranial tibial artery (1.18±0.19 mm), brachial artery (1.08±0.15 mm), ulnar artery (0.82±0.13 mm), and radial artery (0.56±0.12 mm), and the order of size was consistent across all subjects. Thicknesses of the tunica adventitia and media were also diverse, ranging from 74.09±19.91 µm to 158.66±40.25 µm (adventitia) and from 31.2±7.13 µm to 154.15±46.48 µm (media), respectively. Mean dissection time was <3 minutes for all vessels. CONCLUSIONS: Our results suggest that nonliving chickens can provide various vessels with different anatomic characteristics, which can allow trainees the choice of an appropriate microvascular anastomosis training model depending on their purpose and skillfulness.

This study provides a systematic review of the literature on nipple-sparing mastectomy and necrotic complications in order to estimate the prevalence of necrotic complications and to investigate their significant predictors. A literature search was conducted using the MEDLINE and Ovid databases. A pooled analysis was performed for calculation of the prevalence of nipple-areolar complex (NAC) necrosis, mastectomy flap necrosis, and overall necrotic complications and to evaluate the relationships between necrotic complications and potential risk factors. A total of 44 papers were analyzed. The prevalence of overall necrotic complications was 13.7%, including 7.5% for NAC necrosis and 7.8% for mastectomy flap necrosis. Types of incisions showed significant association with the rates of NAC necrosis and mastectomy flap necrosis. Incisions involving the NAC showed a significantly higher rate of NAC necrosis than those not involving it. The prevalence of NAC necrosis was higher in the autologous tissue reconstruction group than in the prosthesis group. Active smoking and diathermy dissection were significant predictors of both NAC necrosis and mastectomy flap necrosis. The findings of this review suggest that there are several predictors of necrotic complications in nipple-sparing mastectomy. Appropriate patient selection, careful operative planning, and surgical technique refinements may reduce the risk of necrotic complications.

Lymphedema is a common complication after mastectomy in breast cancer patients. Many treatment options are available, but no treatment results in a complete cure. We report a case of lymphedema that occurred after modified radical mastectomy in a breast cancer patient who showed objective improvement after delayed breast reconstruction with an latissimus dorsi myocutaneous flap. A 41-year-old female patient with left breast cancer had undergone modified radical mastectomy with axillary lymph node dissection and postoperative radiotherapy 12 years previously. Four years after surgery, lymphedema developed and increased in aggravation despite conservative treatment. Eight years after the first operation, the patient underwent delayed breast reconstruction using the extended latissimus dorsi myocutaneous flap method. After reconstruction, the patient's lymphedema symptoms showed dramatic improvement by subjective measures including tissue softness and feeling of lightness, and by objective measures of about 7 mL per a week, resulting in near normal ranges of volume. At a postoperative follow-up after 3 years, no recurrence was observed. Delayed breast reconstruction with extended latissimus dorsi myocutaneous flaps may be helpful to patients with lymphedema after mastectomy. This may be a good option for patients who are worried about the possibility of the occurrence or aggravation of secondary lymphedema.

BACKGROUND: The purpose of this study is to compare the difference of the symptom, sign and laboratory findings among chronic inflammatory bowel diseases such as ulcerative colitis, Crohn's disease and tuberculous colitis in Korea. METHODS: We studied in Chungnam National University Hospital from March, 1990 to December, 1998. Seventy-eight cases of ulcerative colitis, fifteen cases of Crohn's disease, and thirty-nine cases of tuberculous colitis were analyzed in terms of age, sex, symptomatology, laboratory findings, radiologic findings and consequence of treatment. RESULTS: The sex ratio of ulcerative colitis, Crohn's disease and tuberculous colitis were 1.17:1, 1.14:1, and 1.29:1, respectively, and the mean age were 39.3, 26.5 and 36.0 years, respectively. The most common symptoms of ulcerative colitis, Crohn's disease and tuberculous colitis were bloody stool, diarrhea, and abdominal pain, respectively. In terms of symptoms and signs, we found that significant differences were bloody stool, diarrhea, and weight loss. Patients with tuberculosis colitis revealed significantly high rate of tuberculous lesion on chest X-ray. Among them, 14(35.9%) of the cases showed active tuberculous lesions. In terms of anatomical distribution of the lesion, the most frequently involved sites of ulcerative colitis, Crohn's disease and tuberculous colitis were rectosigmoid colon. descending colon, and ileocecal valve, respectively. CONCLUSION: In differential diagnosis of ulcerative colitis, Crohn's disease and tuberculous colitis, we should consider clinical findings, laboratory findings, colonoscopic appearance, histologic assessment, anatomical distribution of the lesions, and treatment course.

A carcinoid tumor of the stomach is uncommon, has no clinical symptoms, and is regarded as a benign. It is also incidentally found in most cases. 48-year-old woman with gastric carcinoid tumor was admitted. She had suffered from a anorexia and a dry mouth for 4-months. A gastroscopy revealed a polypoid mass on the greater curvature of the mid-body of the stomach which was subsequently thought to be an adenocarcinoma. An endoscopic mucosectomy revealed however, that it was a carcinoid tumor. A case of carcinoid tumor of the stomach is here by presented with a brief literature review.

Salmonella infection is an acute systemic disease that can lead to diffuse organ involvement with septicemia and cause clinically a variety of complications. But acute acalculous cholecystitis and acute hepatitis with jaundice due to Salmonella typhi occurred rarely. A 42 years old female was admitted with fever, chilling sensation and abdominal pain. On admission, the blood, stool, bile acid and bone marrow cultures were positive for Salmonella typhi. The patient had subsequently developed acute acalculous cholecystitis and acute hepatitis with jaundice. Her symptoms and signs resolved after cholecystostomy, parenteral antibiotic (ciprofloxacin) and supportive treatment. We report a case of acute acalculous cholecystitis and acute hepatitis with jaundice in a 42-ear-ld female, whose conditions were recovered completely after cholecystostomy and administration of ciprofloxacin, with reviewing the literatures.
