Aim: To evaluate the outcome of stapled versus sutured colo-rectal anastomosis after low anterior resection of mid-rectal carcinoma. Patients and Methods: A prospective study of fifty patients who underwent colo-rectal anastomosis following low anterior resection (LAR) of T2 mid-rectal cancers at the Egyptian National Cancer Institute during the time period from June 2010 to June 2013 was conducted. Classification was into two groups; a stapled anastomosis group I (25 patients) and a hand-sewn anastomosis group II (25 patients). All operations are evaluated regarding intra-operative complications such as anastomotic line bleeding, visceral injuries or major blood loss. The anastomotic time and operative time are documented for each operation. All patients are evaluated post-operatively for anastomotic leakage (AL), wound infection and ileus. Results: The distance of the tumor from the anal verge was $9.6{\pm}2.0cm$ in group I and $9.9{pm}2.4cm$ in group II. The mean operative time was $191.5{\pm}16.2min$ in the stapled group and $208{\pm}18.6min$ in the sutured group (p=0.002). The mean anastomotic times were $9.0{\pm}1.9min$ and $19.7{pm}12.2min$ (p=0.001). Anastomotic leakage developed in three (12.0%) patients in the stapled group and in four (16.0%) patients in the sutured group (p=1.000). Post-operative ileus was observed in 3 patients in group I and one patient in group II. Wound infection developed in three (12.0%) patients in the stapled group and four (16.0%) patients in the sutured group (p=1.000). Conclusion: Colo-rectal anastomosis after low anterior resection for mid rectal carcinoma can be conducted safely either by stapling or hand-sewn techniques; however the stapling technique showed shorter anastomotic and operative times with no significant advantages regarding intra- or post-operative complications or hospital stay.

Background The aim of this investigation was to systematically review the current literature to provide the best data for indications, outcomes, survival, and complication rates of pedicled propeller perforator flaps for upper body defects. Methods A comprehensive literature review for articles published from January 1991 to December 2011 was performed using the PubMed, Medline, and Cochrane Databases. Articles without available full-text, single case reports or papers with excessive missing data were excluded. Papers reporting pedicle-perforator (propeller) flaps used for lower extremity reconstruction were excluded from meta-analysis. Results From the initial 1,736 studies our search yielded, 343 studies qualified for the second stage of selection. Of 117 full-text reports screened, 41 studies, met the definitive inclusion and exclusion criteria. Of the selected 41 articles, 26 were case series, original papers or retrospective reviews and were included, whereas 15 were case report papers and therefore were excluded. Two hundred ninety-five propeller flaps were reported to have been used in a total of 283 patients. Indications include repair of trauma-induced injuries, post-trauma revision surgery, cancer resection, chronic infection, pressure sores, and chronic ulcers with a major complication rate (3.3%) comparable to that of free flaps. No specific exclusion criteria for the procedure were presented in the studies reviewed. Conclusions Pedicled propeller flaps are a versatile and safe reconstructive option that are easy and quick to raise and that provide unlimited clinical solutions because of the theoretical possibility of harvesting them based on any perforator chosen among those classified in the body.

There has been considerable controversy as to the treatment method of dislocation of the acromioclavicular joint, so various operative treatment modalities have been suggested. We analyzed the results of 40 patients with acromio­clavicular dislocation, in whom twenty patients were treated by modified Phemister method and 20 patients by modified Weaver-Dunn method above follow-up two years. The purpose of this study was to compare the clinical results of two operative methods. According to Weitzman criteriae for clinical results, 12 cases were excellent, six cases good and two cases fair in modified Phemister method. But in modified Weaver-Dunn method, ten cases were excellent, eight cases good, one case fair and one case poor. In radiological result, coracoclavicular distance was measured at preoperative, postoperative and last follow-up period. The modified Phemister method was 6.lmm, 1.5mm and 2.4mm respectively, and the modified Weaver-Dunn method 7.8mm, 2.lmm and 2.5mm respectively. The complications were two cases of heterotopic ossification, one case of inadequate fixation and one case of K-wire breakage in modified Phemister method, and two cases of early fixation loss and one case of heterotopic ossification in modified Weaver-Dunn method. We obtained that the clinical, functional and radiological results showed no significant difference in two methods. The modified Phemister method was effective treatment for old patients in acute injuries due to short operation time and simple technique. The modified Weaver-Dunn method, as a reconstructive operation that reduces various complications for young and active male patients, was also good for getting the stability of coraco­clavicular ligament through clavicular bony union.

The purpose of this study was to investigate humeral translation relative to the glenoid invivo during loaded and unloaded shoulder abduction. CT scans of 9 healthy shoulders were acquired and 3D models were created. The subject was positioned in front of a fluoroscope and motions were recorded during active abduction. The subjects performed two trials of holding a 3kg weight and unload. 3D motions were determined using model-based 3D-to-2D registration to obtain 6 degrees of freedom kinematics. Glenohumeral translation was determined by finding the location on the humeral head with the smallest separation from the glenoid. Humeral translation was referenced to the glenoid center in the superior/inferior direction. The humerus moved an average of 2 mm, from inferior to central on the glenoid, during arm abduction for both conditions. The humeral head was centered within 1mm from the glenoid center above $70^{\circ}$. There were no statistically significant differences for both conditions. The standard deviation decreased gradually over the motion, with significantly lower variability at the end of abduction compared to the initial unloaded position. We assumed that the humeral translation to the center of the glenoid provides maximum joint congruency for optimal shoulder function and joint longevity. We believe this information will lead to better strategies to prevent shoulder injuries, enhance rehabilitation, and improve surgical treatments.

Purpose: The hand is frequently affected area in high voltage electrical burn injury as an input or output sites. Electrical burn affecting the hand may produce full thickness necrosis of the skin and damage deep structures beneath the eschar, affecting the tendon, nerve, vessel, even bone which result in serious dysfunction of the hand. As promising methods for the reconstruction of the hand defects in electrical burn patients, we have used the peroneal perforator free flaps. Methods: From March 2005 to June 2006, we applied peroneal perforator free flap to five patients with high tension electrical burn in the hand. Vascular pedicle ranged from 4cm to 5cm and flap size was from $4{\times}2.5cm$ to $7{\times}4cm$. Donor site was closed primarily.Results: All flaps survived completely. There was no need to sacrifice any main artery in the lower leg, and there was minimal morbidity at donor site. During the follow-ups, we got satisfactory results both in hand function and in aesthetic aspects.Conclusion: The peroneal perforator flap is a very thin, pliable flap with minimal donor site morbidity and is suitable for the reconstruction of small and medium sized wound defect, especially hand with electrical burn injury.

Recurrent laryngeal nerve paralysis is the most common and serious complication after thyroid cancer surgery. The objective of this study was to report the advantages of the vein wrapping technique for nerve reconstruction in patients with thyroid cancer invading the recurrent laryngeal nerve and its effects on postoperative phonatory function. The subjects were three patients who underwent resection of the recurrent laryngeal nerve during surgical extirpation of papillary thyroid cancer. Free ansa cervicalis nerve graft or direct neurorrhaphy with a vein wrapping technique was used to facilitate nerve regeneration, protect the anastomosed nerve site mechanically, and prevent neuroma formation. One-year postoperative laryngoscopic examination revealed good vocal cord mobility. Maximum phonation time ($19.5{\pm}0.3$ sec) was longer than a previously-reported value in conventional reconstruction patients ($18.8{\pm}6.6$ sec). The present phonation efficiency index ($7.88{\pm}0.78$) was higher than that previously calculated in conventional reconstruction ($7.59{\pm}2.82$). The mean value of the Voice Handicap Index-10 was 6, which was within the normal range. This study demonstrates improvement in phonation indices measured 1 year after recurrent laryngeal nerve reconstruction. Our results confirm that the vein wrapping technique has theoretical advantages and could be favored over conventional reconstruction techniques for invenerate nerve injuries.

Purpose: We report the surgical outcomes for femoral shaft fractures in polytrauma patients who were temporarily treated with external fixation and subsequently converted to internal fixation. Methods: From August 2008 to April 2012, we enrolled 13 patients with multiple traumas due to high-energy injuries and concurrent femoral shaft fractures in which temporary external fixation was carried out. The mean age was 39 years, with a range from 18 to 55 years. Ten were men and 3 were women. According to the AO/OTA classification of fractures, type A was found in 5 patients, type B in 6, and type C in 2, with open fractures being found in 6 patients and femoral artery rupture occurring in 2. For internal fixation, intramedullary nailing was performed in 7 patients, and minimally-invasive fixation of locking compression plates was used in 6. Results: Of the 7 patients converted to intramedullary nailing, 1 experienced delayed union. Of the 6 patients treated with minimally-invasive plate fixation, delayed union occurred in 5, and an auto-bone graft was performed within, on average, 8 months (range: 5~10 months), leading to bone union in all cases in the final follow-up. None of the patients experienced infections or complications involving other organs after having been converted to internal fixation. During the mean follow-up of 19 months, patients achieved satisfactory functional outcomes. Conclusion: In polytrauma patients with a femoral shaft fracture who have been treated with temporary external fixation and who may need internal fixation due to the occurrence of delayed union, an appropriate internal fixation method needs to be selected based on the patient's physical status, and the fracture type.

The surgical reconstruction of major defects of the head and neck such as those following accidental injuries or resection of tumors has been facilitated and advanced by the development of myocutaneous flaps which provide both muscle bulk and skin coverage. Of the many available myocutaneous flaps, the pectoralis major myocutaneous flap has many advantages such as abundant tissue with an excellent vascularity, anatomic proximity, long arc of rotation, reliability and versatility, so it is used most frequently in head and neck reconstruction. It is the purpose of this paper to present our experiences with two cases of pectoralis major myocutaneous island flaps used in reconstruction of major defects of face; one is after resection of very large basal cell carcinoma of the left oral commissure and the other is after resection of a huge fibrous mass and destructed facial bones caused by chronic osteomyelitis.

A retrospective study has been carried out for 47 cases of traffic accident victims which was entered to the Dongguk Bundang O. M. Hosp. from Jan 1, 1999 to May 4, 2000. This study was focused on finding out the distribution, pattern of the traffic accidents, clinical characteristics of the patients, motives of their choosing oriental medical treatments, the kinds of oriental medical treatment. This results were as follows : 1. The highest incidence was shown in the age of twenties to thirties as much as 59.6% and the ratio of male to female was 17:30. 2. 80.9% of all patients was injured by car accidents. 68.2% of all patients was injured as drivers and passengers and 19.2% was injured as pedestrians. The highest type in the collision between cars, was rear impact. 3. The number of patient(61.7%) via other hosp. was more than that of the first visitor(38.3%) to our hosp. 4. In admission motives, The patients who had been treated by western medical treatment, expressed the dissatisfaction of that treatment, so hoped to be treated by oriental medical styles. Also The others wanted to be treated by oriental medical methods in the reason of no deep surgical, orthopaedical lesions 5. C-spine sprain(80.9%) was the most frequent out of all patients's diagnosis and then L-spine sprain(51.1%), contusion(46.8%), etc. 6. Head Cervix(80.9%) was the commonest pain region of all patients. and then shoulder back(70.2%), lumbar region(61.7%), etc. 7. In general, the pedestrian injuries were more serious than those sustained in the car as passengers. 8. After discharge, Duration of OPD treatment was long as much as that of admission treatment. 9. At first stage of admission period, Herb medication was frequently prescribed for hwalhyultonglakgige(活血通絡之劑). but As going to end stage, was frequently used for bogi(補氣) bohyul(補血), gudam(祛痰), ansin(安神).

Background: The objective of the present study was to examine the status of patients who had received dental treatment under intravenous (IV) sedation at Chungnam Dental Clinic for the Disabled in Korea from its inception to the present time, and to review the analysis results. Methods: Retrospective analysis was performed on 305 cases of patients who had received dental treatments under IV sedation between January 2011 and May 2016. The analysis examined the patient's sex, age, primary reason for IV sedation, duration of anesthesia and dental treatment, type of dental treatment performed, number of clinical departments involved in the dental treatment and level of multidisciplinary cooperation, and annual trends. Results: Most dental treatments using intravenous sedation were performed on medically disabled patients or dentally disabled patients with an extreme gag reflex or dental phobia. The mean duration of IV sedation was 72.5 min, while the mean duration of treatment was 58.0 min. The types of dental treatments included surgical treatment (n = 209), periodontal treatment (n = 28), prosthodontic treatment (n = 28), restorative treatment (n = 23), implant surgery (n = 22), endodontic treatment (n = 9), reduction of temporomandibular joint dislocation (n = 1), and treatment of traumatic injuries (n = 1), with treatments mostly performed on adult patients. Conclusions: With increasing demand for minimally painful treatment, cases using IV sedation are on an upward trend and are expected to continue to increase.
