OBJECTIVETo investigate the clinical application of flow-through deep inferior epigastric perforator flaps for reconstruction of large defects at the extremities.

METHODSThe deep inferior and superior epigastric arteries were designed as the axial vessel and the arterial supply to the flap was the paraumbilical perforator artery. Free deep inferior epigastric perforator flaps were harvested in flow- through manners to reconstruct associated arterial defect in the wound. The sensation assessment,Enneking score,and questionnaire of the flap aesthetic were all performed during follow-up period.

RESULTSFrom December 2011 to September 2012, 5 patients with large defects at extremities were treated. The deep inferior and superior epigastric arteries were designed as the axial vessel and the arterial supply to the flap was the paraumbilical perforator artery. The wound defects ranged form 11 cm x 5 cm to 30 cm x 11 cm. And the flap size ranged from 13 cm x7 cm to 33 cm x 13 cm. All flaps survived completely. The recipient arteries were all bypassed well documented by color Doppler examinations. All cases had 12-24 months' follow-up period. The flaps had good appearance and high aesthetic satisfactory(100%). 12 months after operations, sensation assessment were all S3+, and the Enneking score ratios were 82%-95% ,with 87.2% in average.

CONCLUSIONSFlow-through deep inferior epigastric perforator flaps are reliable and effective for reconstruction of large defects at the extremities with maintenance of the vascular status of the extremities. The flaps can also be designed in transverse or oblique mode for clinical application.

On May 14, 2020, a 37 year old female patient with unilateral breast cancer was admitted to Hunan Cancer Hospital. She underwent modified radical mastectomy for right breast cancer and free transplantation of bilateral superficial inferior epigastric artery perforator flap (weighed 305 g) for breast reconstruction. During the operation, the right inferior epigastric vascular pedicle was anastomosed with the proximal end of the right internal mammary vessel, and the left inferior epigastric vascular pedicle was anastomosed with the distal end of the right internal mammary vessel; the blood flow of the flap was good; the wound in the donor site of the abdominal flap was closed directly. The operation lasted for 9 hours. In the first 48 hours post operation, the flap showed mild elevation in perfusion over drainage, but no obvious edema or blister was observed, flap temperature was consistent with the surrounding skin, and the drainage volume out of drainage tube was only 40 mL. The blood supply of the flap was completely restored to normal 3 days post operation, the flap survived well, the donor site incision had no obvious tension, and the healing was smooth. After 2 months of follow-up, the donor site incision of abdomen healed completely, only linear scar was left, and the reconstructed breast had a natural appearance; the patient planned to perform further nipple reconstruction and contralateral breast mastopexy. This case suggests that autologous breast reconstruction can be performed using bilateral superficial inferior epigastric artery perforator flaps under certain circumstances to minimize donor site injury to the greatest extent.

OBJECTIVETo explore a new surgical procedure for vaginal reconstruction with pedicled deep inferior epigastric perforator (DIEP) flap.

METHODSSince June 2007, 6 cases underwent vaginal reconstruction, including five congenital vaginal absence and one immediately after total vaginal resection due to carcinoma. Intensive CT scans were performed preoperatively for perforator selection. The DIEP flaps were designed vertically on the anterior abdominal wall and transferred for vaginal reconstruction.

RESULTSAll the patients recovered uneventfully with no flap loss and other complication. The patients were followed up for 1 to 8 months (mean, 4 months) with satisfactory results.

CONCLUSIONVaginal reconstruction with vertical DIEP flaps is a safe and reliable method.

OBJECTIVE: To explore the effectiveness of folded transverse superficial epigastric artery perforator flap in repairing the large penetrating defect after buccal carcinoma resection. METHODS: Between January 2019 and June 2021, 12 patients with buccal squamous cell carcinoma were treated. There were 6 males and 6 females with an average of 66.9 years (range, 53-79 years). The pathological stage was T3a-T4b, and the preoperative mouth opening was (3.08±0.46) cm. The disease duration ranged from 6 to 24 months, with an average of 15 months. After buccal carcinoma radical resection and neck lymph node dissection, the penetrating defects in size of 8 cm×6 cm to 16 cm×8 cm and in depth of 0.5-1.5 cm were remained. The transverse superficial epigastric artery perforator flap in size of 8 cm×6 cm to 14 cm×8 cm were harvested and folded to repair the penetrating defects. The donor site was sutured directly. RESULTS: All 12 skin flaps survived after operation, and the wounds healed by first intention. No internal or external fistula complications occurred. All incisions at the recipient site healed by first intention. All patients were followed up 12-18 months (mean, 14 months). There was no obvious abnormality in the color and texture of the flap, the oral and facial appearances were symmetrical, and there was no obvious swelling in the cheek. At last follow-up, the patient's mouth opening was (2.89±0.33) cm, which was not significantly different from that before operation ( t=1.879, P=0.087). The subjective satisfaction scores of 12 patients were 6-8 points, with an average of 7.3 points. Significant scars remained at the donor site but concealed in location. CONCLUSION The folded transverse superficial epigastric artery perforator flap can be used as a surgical method for repairing large penetrating defects after the buccal carcinoma resection, with a good recovery of facial appearance and oral function.

OBJECTIVETo explore the feasibility and the effect of free chimeric perforator flap with deep inferior epigastric artery for the soft tissue defect on the lower extremity with deep dead space.

METHODSFrom Mar. 2010 to Aug. 2011, 8 patients with soft tissue defects on the lower extremities combined with dead space, bone or joint exposure were reconstructed with free hinged perforator flaps with deep inferior epigastric artery. The muscle flap was inserted into the deep dead space, with perforator flap for superficial defect. The defects on the donor sites were closed directly.

RESULTSAll the flaps survived with primary healing. Good color and texture was achieved. The patients were followed up for 12-24 months, with an average of 16 months. 2 over-thick flaps were treated by flap-thinning surgery. Only linear scar was left on the donor site on abdomen with no malfunction.

CONCLUSIONSThe free chimeric perforator flap with deep inferior epigastric artery can simultaneously construct the dead space and superficial defect with only anastomosis of one set of vascular pedicle. It is an ideal method with good results on recipientsites and less morbidity on donor sites.

PURPOSE: Our experience of laparoscopic radical prostatectomy, for clinically localized prostate cancer, is reported. MATERIALS AND METHODS: Between July 2001 and August 2002, laparoscopic radical prostatectomy was performed on 16 patients with clinically organ confined prostate cancer. Their mean age, preoperative PSA and Gleason score for the biopsy specimens were 63.9 years old, 12.2ng/ml and 5.6, respectively. The "Montsouris" operation technique was followed, and an urethrovesical anastomosis performed with 5 to 10 interrupted sutures. RESULTS: Mean operation time and hospital stay were 347 minutes, ranging from 250 to 500, and 8.3 days, ranging from 3 to 12. Conversion to open surgery was necessary in one case due to difficulty with the urethrovesical anastomosis. Three cases needed a blood transfusion with a mean of 2.3 units. Mean postoperative period of an indwelling Foley catheter was 15.4 days (5-36). The intraoperative complications related to the operation procedures were one epigastric artery injury and two vesicle injuries. There was a positive surgical margin in five cases. The postoperative pathological evaluations comprised of 1 pT0, 5 pT2a, 3 pT2b and 7 pT3a. The PSA value decreased to less than 0.5ng/ml after the laparoscopic radical prostatectomy, with the exception of one case. CONCLUSIONS: Although the mean operation time was still longer than that of conventional open procedures, an intraoperative magnified vision allows for more precise and safer dissections and a meticulous urethrovesical anastomosis. We believe the operative time will decrease further with more experience. The perioperative morbidity with the laparoscopic radical prostatectomy was low. The continence following a laparoscopic radical prostatectomy was comparable to that after an open radical prostatectomy. These results show that a laparoscopic radical prostatectomy can be an acceptable treatment option for localized prostate cancer.

OBJECTIVETo explore the distribution of deep inferior epigastric perforator vessel and application of the expanded perforator flap for large scar on hand and forearm.

METHODS20 healthy adults were selected to detect the distribution of deep inferior epigastric perforator vessel. 10 cases with cicatricial constriction on hand and forearm were treated with expanded perforator flap.

RESULTS425 perforator points were detected on the skin surface of abdomen in 20 adults. 80% of the points are located within the area which is 1.1 -5.8 cm far from the mid-line of abdomen. According to the Rand method, the percentage of the points in zone I , II , III were 26%, 43%, and 30%, respectively. There were few points in zone IV. The area around navel had a high density of points. The points were distributed asymmetrically at the two sides of abdomen. 10 cases were treated. Vascular deficiency happened at the distal end of one flap. All the other 9 flaps survived.

CONCLUSIONSThe expanded deep inferior epigastric perforator flap is thin and has a large size. It is very suitable for large scar on forearm or hand.

epigastric artery anatomy, easy to dissect with well defined skin boundaries, acceptable donor site morbidity and the ability to perform simultaneous flap harvest with oral cancer ablation surgery. The rectus abdominis muscle forms an important part of the anterior abdominal wall and flexes the vertebral column, which is a long strap-like muscle divided transversely by three tendinous intersections, fibrous bands which are adherent to the anterior rectus sheath, which is thickly enclosed by the rectus sheath, except for the posterior part below the arcuate line that is usually located midway between the umbilicus and symphysis pubis. Below the arcuate line, this muscle lies in direct contact with the transversalis fascia and parietal peritoneum. For the better understanding of RAMFF as a routine reconstructive procedure in oral and maxillofacial surgery, the constant anatomical findings muse be learned and memorized by the young doctors in the course of the special curriculum periods for the Korean national board of oral and maxillofacial surgery. This review article will discuss the anatomical basis of RAMFF with Korean language.]]>

Therapeutic paracentesis is considered to be a relatively safe procedure and is performed commonly for the control of massive ascites in patients with liver cirrhosis. The commonest puncture site, approximately 4 or 5 cm medial of left anterior superior iliac spine, can be located across the route of the inferior epigastric artery, which is one of the sites of potential massive bleeding. In a 46-year-old woman with liver cirrhosis and refractory ascites, a huge abdominal wall hematoma developed after therapeutic paracentesis. The patient was not stabilized by conservative treatment, and inferior epigastric artery injury was confirmed on angiography. Angiographic coil embolization of the inferior epigastric artery was conducted, after which the bleeding ceased and the hematoma stopped growing. This case indicates that physicians performing paracentesis should be aware of the possibility of inferior epigastric artery injury and consider early angiographic coil embolization when a life-threatening abdominal wall hematoma develops.
