The management of skin and soft tissue defects on the buttock, perineum and lower abdomen has been improved through the development of myocutaneous flap. However, sacrifice of the deep muscles causes some problems such as intraoperative bleeding and functional disabilities of donor sites. And we can not also control the volume of the flap for the skin reliability of myocutaneous flaps. To overcome these disadvantages, we tried perforator-based myocutaneous island flaps for the reconstruction of the sacral, ischial sores or deep wounds of the perineum and lower abdomen. During the dissection of the flap, we could control the volume and shape of the flap exactly depending on the perforators. Clinically, total of 14 cases were treated with 10 parasacral perforator-based myocutaneous island flaps and 4 perforator-based extended myocutaneous island flaps. Parasacral flap is based on the parasacral perforators along the lateral sacral border and, the degree of containing muscles can be easily decided according to the depth of wound. In the cases of the extended myocutaneous flaps, we could design the perforator-based skin flap on the tip of myocutaneous island flap and appropriate volume of skin falp was obtained with the wide arc of rotation. Finally, the donor defect could be closed primarily and there was no significant sequela. There perforator-based myocutaneous island flaps require no significant sacrifice of the muscles and can be easily dissected and applied with the appropriate volumes for the reconstruction of the defect on the buttocks, perineum and lower abdomen.

Puerperal genital hematomas are rare but life-threatening complications of obstetric emergencies. A pregnant patient (39 weeks) underwent a mediolateral episiotomy during a vaginal delivery. An afterbirth hematoma (approximately 20 cm in diameter) was evacuated, but the use of a vacuum-assisted wound closure system was applied after the sutures opened on the 7th postoperative day. On the 10th day of the vacuum-assisted closure (VAC) application, the wound was completely closed. VAC is an alternative treatment modality that can drain an infection and increase the proportion of granulation tissue in humid and irregular surfaces such as the perineum.

OBJECTIVE: To study the characteristics and biomechanical mechanism of riding injuries involving bicycles collided by motor vehicles. METHODS: The real traffic accident cases of bicycles collided by motor vehicles, including the information of scenes, bicycles, motor vehicles, rider wounds and traffic directions, were collected. Retrospective method was used to study these riding injuries. In addition, typical cases were selected to simulate traffic accident courses with computer simulation software, and the dynamic data like acceleration, force, moment were cxtracted to compare with those in the real cases. RESULTS: There were no difference of occurring frequency between cases with or without riding injuries, as well as between one-side-collision and front- or back-collision. The riding injuries seemed less in accidents involving large-scale vehicles. The frequency of riding injuries increased with vehicle speed. The wound location was low on collision side and high on opposite. CONCLUSION Analysis of riding injury characteristic in traffic accidents and their biomechanical mechanism would be helpful for estimation of traffic manner.

BACKGROUND: Perineal defects are commonly encountered during the treatment of conditions such as malignancy, infectious disease, and trauma. Covering large defects in the perineal area is challenging due to its complicated anatomy and the need for functional preservation. METHODS: Fourteen patients who underwent reconstructive surgery with multiple perforator flaps for defects >100 cm2 in the perineal area were included in this retrospective cohort study. Characteristics of the perforator flap operation and postoperative outcomes were reviewed. RESULTS: Reconstruction was performed using 2 perforator flaps for 13 patients and 3 perforator flaps for 1 patient. Internal pudendal artery perforator flaps were mainly used for covering the defects. The average defect size was 176.3±61.8 cm2 and the average size of each flap was 95.7±31.9 cm2. Six patients had minor complications, such as wound dehiscence and partial necrosis of the flap margin, which were corrected with simple revision procedures. CONCLUSIONS: Multiple perforator flaps can be used to achieve successful reconstructions of large perineal defects that are difficult to reconstruct with other coverage methods.

PURPOSE: We reviewed recent 10 year experience in the diagnosis and treatment of patients with erectile dysfunction associated with various injuries. MATERIALS AND METHODS: Seven hundred sixty patients were admitted for evaluation of erectile dysfunction from January 1988 to April 1997. Among the 760 patients, 90 patients had erectile dysfunction associated with injuries. Mean age was 34.1 years(range 20-63). We classified the types of injury and analyzed etiologies of erectile dysfunction caused by various injuries and treatment modalities. RESULTS: Spinal cord injury was observed in 38(42.2%) patients, urethral injury in 11(12.2%), pelvic bone fracture in 5(5.5%), urethral injury with pelvic bone fracture in 22(24.4%), penile injury in 8(8.8%) and blunt trauma to the pelvis and perineum in 6(6.6%). Of the patients with spinal cord injury, neurogenic erectile dysfunction was observed in36(95%) patients. Erectile dysfunction by hemodynamic abnormalities was observed in 6(55%), 4(80%), 11(50%), 5(63%) and 6(100%) in patients with urethral injury, pelvic bone fracture, urethral injury with pelvic bone fracture, penile injury and blunt trauma to the pelvis and perineum, respectively. Among the 90 patients, 58 received surgical therapy and 21 intracavernosal injection therapy and the others were only evaluated for accurate diagnosis. Arterialization of deep dorsal vein was performed in 2 patients, ligation of deep dorsal vein in 2 and penile prosthesis implantation in 56. CONCLUSIONS: A high frequency of hemodynamic abnormalities was observed in patients with erectile dysfunction caused by various injuries except for spinal cord injury. Among the patients who were treated surgically, penile prosthesis implantation was most successfully performed(96.6%).

The use of a gracilis myocutaneous flap to overlay an extensively traumatized scrotoperineal soft tissue defect, through which both testes and the ruptured bulbous urethra were exposed, is discussed. The transplanted gracilis myocutaneous flap, which included vascularized and innervated tissue, was well taken and covered the perineal defect, exposed testes and urethral stricture both cosmetically and functionally.

Even though sphincter saving surgery such as coloanal anastomosis or intersphincteric resection have been popular in era of Total Mesorectal Excision (TME) in distal rectal cancer, unreasonable sphincter saving surgery might cause a couple of troublesome complications in terms of oncologic or functional outcomes. Since preoperative staging work up recently have been developed with MRI or MDCT, it is important to assess whether rectal cancer invaded into surrounding sphincter or levator ani muscle based on MRI or MDCT coronal image study. If tumor is located at a very close distance or has invaded the adjacent sphincter muscle, the need of abdominoperineal resection is definite without any hesitation for curative resection. But, the actual number of cases of APR have been decreased in favor of sphincter preserving surgery even APR remains an important therapeutic option in the surgical treatment of low rectal cancer. Indication case for APR have become a intersphincteric resection or ultralow anterior resection and coloanal anastomosis Even patients who showed invasion of sphincter underwent sphincter saving surgery, lately proven safe in terms of recurrence and defecation functions. On practical view points on operative techniques, abdominal phase are same as TME techniques. Sharp pelvic dissection must be carried out along the visceral fascia enveloping the mesorectum to the levator ani muscle with preservation of pelvic autonomic nerve. Perineal phase dissection is a key process in APR. During perineal dissection, inadequate resection margin and blunt tissue dissection along the nonanatomical plane encourage implantation of a malignant cell and local recurrence. Moreever, it could lead to serious complications such as prostatic urethral injury, vaginal wall perforation, perineal sinus and fistula. Massive bleeding from pelvic side wall major vessels injury. Especially in males with very narrow pelvis, pelvic dissection is very difficult due to deep narrow and blunt sacral curvature of the pelvis. It is nearly impossible to reach the levator ani muscle and result in perineal dissections performed on excessively high levels. For colorectal surgeons with insufficient experience, it is difficult to dissect the rectum from the perineum upto the seminal vesicle level. In the classic pattern, anterior and lateral dissection from the prostate or vagina after the completion of posterior dissection. The dissected proximal colon was delivered outward through the perineal wound and with traction of the delivered portion of the colon, anterior dissection was performed. However, in patients with narrow pelvis, such delivery of the proximal colon through perineal wound can result in fractured tumor and local recurrence due to limited operation field. Therefore, it is mandatory that specimen must be delivered in situ after posterior, anterior and lateral dissection. During posterior dissection, gluteus muscle must be observed and removal of the ischiorectal fat tissue should be accomplished. In lateral dissection, levator ani muscle must be divided near the bony insertion. Finally, during anterior dissection, seminal vesicle and prostate gland must be exposed and neurovascular bundle observed at the 10 and 2 o'clock direction. In addition to TME on abdominal phase, Sharp Anatomical Perineal Dissection (SAPD) empowered by 3D concept based on MRI is a key process for prevention of local recurrence in APR.

PURPOSE: A sacral chordoma is a rare, slow-growing, primary bone tumor, arising from embryonic notochordal remnants. Radical surgery is the only hope for cure. The aim of our present study is to analyse our experience with the challenging treatment of this rare tumor, to review current treatment modalities and to assess the outcome based on R status. METHODS: Eight patients were treated in our institution between 2001 and 2011. All patients were discussed by a multidisciplinary tumor board, and an en bloc surgical resection by posterior perineal access only or by combined anterior/posterior accesses was planned based on tumor extension. RESULTS: Seven patients underwent radical surgery, and one was treated by using local cryotherapy alone due to low performance status. Three misdiagnosed patients had primary surgery at another hospital with R1 margins. Reresection margins in our institution were R1 in two and R0 in one, and all three recurred. Four patients were primarily operated on at our institution and had en bloc surgery with R0 resection margins. One had local recurrence after 18 months. The overall morbidity rate was 86% (6/7 patients) and was mostly related to the perineal wound. Overall, 3 out of 7 resected patients were disease-free at a median follow-up of 2.9 years (range, 1.6-8.0 years). CONCLUSION: Our experience confirms the importance of early correct diagnosis and of an R0 resection for a sacral chordoma invading pelvic structures. It is a rare disease that requires a challenging multidisciplinary treatment, which should ideally be performed in a tertiary referral center.

BACKGROUND: The main causes of death in patients with open pelviperineal injuries are uncontrollable bleeding and pelvic sepsis. The aim of this study was to evaluate the management outcomes of open pelvic fractures associated with extensive perineal injuries. METHODS: We retrospectively studied 15 cases with open pelvic fractures associated with extensive perineal injuries (urethral and anal canal laceration) admitted between August 2006 and September 2010. Mechanism of injury, Injury Severity Score, associated injuries, hemodynamic status on arrival, resuscitation and transfusion requirements, operative techniques, intra- and postoperative complications, length of intensive care unit and hospital stay, and mortality were recorded in a computerised database for further evaluation and analysis. RESULTS: The male to female ratio was 12:3 with an average age of 38.6 years (ranged, 11 to 65 years). The average packed red blood cell units used were 8 units (ranged, 4 to 21 units). All patients were initially transferred to the operating room for colostomy, radical debridement and fixation of the pelvic fracture by an external fixator. One patient had acute renal failure, which improved with medical treatment and 2 patients (13.3%) died, one with type III anteroposterior compression fracture due to hemorrhagic shock and the other due to septicemia. CONCLUSIONS: Open pelvic fractures with extensive perineal injuries are associated with high mortality rates. Early diagnosis and appropriate treatment, including reanimation, colostomy, cystostomy, vigorous and repeated irrigation and debridement, and fixation by an external fixator can improve the outcomes and reduce the mortality rate.
