PURPOSE: S-plasty for pilonidal disease reduces the tension on the midline by distributing it diagonally and flattening the natal cleft. The aim of this study was to evaluate the outcomes of S-plasty on simple midline primary closure and the clinical features of pilonidal patients in a low incidence country. METHODS: S-plasty was applied on 17 patients from July 2008 to October 2010. Data of these patients were collected with computerized prospective database forms during a perioperative period and via telephone interview for follow-up. Surgical site infection (SSI) was defined according to the Center for Disease Control guidelines. The severity of surgical site infection was graded. RESULTS: All patients were treated with primary S-plasty. Two patients (11.7%) developed low grade SSI. The average healing time after S-plasty was 18.1 days. No recurrences were observed. The mean follow-up period was 13.5 months (range, 6 to 33 months). CONCLUSION: We have shown that primary S-plasty for pilonidal disease is simple, and its surgical outcomes are compatible to the results of other surgical treatments. We present primary S-plasty as a feasible treatment option in a low incidence country.

Purpose:
The present study compares the peri/postoperative and oncological outcomes of abdominoperineal resections (APR) and sphincter saving resection (SSR) for low lying rectal cancer.
Methods:
Between January 2001 and December 2014, 176 patients who underwent SSR (n = 67) and APR (n = 109) for low rectal cancer, without stage IV, were retrieved from a retrospective database.
Results:
With a median follow-up of 66.5 months. The mean total number of harvested lymph nodes was 16.7 (SSR) versus 17.1 (APR) (P = 0.801). The advanced T stage was higher in the APR group (82.6%) versus the SSR group (55.2%) (P = 0.006). The positive rate of lymph nodes after surgery was significantly higher in the APR group (45.9%) versus SSR group (25.4%) (P < 0.05). The 5-year overall survival rates for SSR and APR were 87.3% and 67.6%, respectively (P < 0.005). The 5-year disease-free survival rate (DFS) was 83.6% (SSR) versus 65.5% (APR) (P = 0.002). The recurrence rate was higher in the APR group (34.9%) versus the SSR group (14.9%) (P = 0.004). Local recurrence rate was not different between the two groups. However, distant recurrence rate was significantly higher in the APR group (26.6% vs. 11.9%, P = 0.023). In multivariate analysis, node positive (N0 vs. N1-2) was an independent prognostic factor for DFS (P < 0.005).
Conclusion
Based on the present data, SSR achieved better 5-year oncological outcome than APR. The positive lymph node ratio in the N stage after surgery was higher in the APR group and this seems to have an effect on the oncological outcomes of the APR group.

BACKGROUND: The nasal mucosa is degenerated by inflammations, physical stimulations such as cessation of air flow, and other chemical stimulations. And it is regenerated regularly by newly differentiated cells. OBJECTIVES: In order to investigate the morphologic changes of the nasal mucosa and regenerating activities in sinusitis. MATERIALS AND METHODS: The authors made animal models of acute maxillary sinusitis by obstructing the natural ostium of maxillary sinus of rabbit and inoculating Staphylococcus aureus colonies. Each contralateral side was used as control. The rabbits were sacrificed after 1, 2, and 3 weeks. Morphologic changes of the nasal mucosa and regenerating activities of the olfactory mucosa were observed with Hematoxylin-eosin staining and immunohistochemistry using BrdU. RESULTS: Purulent sinusitis was developed in all rabbits. Light microscopy showed that nasal mucosa revealed inflammatory changes such as edema, inflammatory cell infiltration, goblet cell metaplasia, polypoid change, epithelial ulceration, and submucosal connective tissue proliferation. BrdU-labelled cells were observed mainly in the basal cell layer of the olfactory mucosa, and their numbers in the control sides were significantly higher than in the experimental sides. CONCLUSION: These results indicate that acute infection of the maxillary sinus induces inflammatory changes of both respiratory and olfactory mucosa of the nose and decreases the regenerating activity of olfactory mucosa.

PURPOSE: Stoma formation has usually been used for bowel decompression or fecal diversion. For these, a cecostomy is rarely performed because of disadvantages such as incomplete fecal diversion or fatal complications. The aim of this study was to evaluate the usefulness of an open cecostomy in treating patients with colonic obstruction. METHODS: Between May 2005 and August 2008, 20 patients underwent an open cecostomy because of colonic obstruction. All information on the patients was reviewed retrospectively for underlying disease, obstruction site, diameter of the cecum and transverse colon, and complications. RESULTS: Of the 20 patients, 14 had colorectal cancer, 3 had stomach cancer, 1 had cervical cancer, 1 had a carcinoid tumor, and 1 had an osteosarcoma. The cause of the obstruction was the primary tumor in 7 patients, peritoneal carcinomatosis in 7 patients, local recurrence in 5, and tissue edema after cyberknife treatment in 1 patient. All patients, except for 1 patient with a hopeless discharge due to rapid disease progression, were discharged on the tenth day postoperatively. No fatal complication developed. In 2 patients, the cecostomy closed spontaneously at 5.5 mo postoperatively after the distal obstruction had been resolved. CONCLUSION: An open cecostomy may be a useful and simple method for the decompression of a colonic obstruction, even though the diversion may not be complete.

STUDY DESIGN: Retrospective study OBJECTIVES: To evaluate the surgical outcome of congenital scoliosis with a hemivertebra treated by posterior hemivertebra excision and pedicle screw instrumentation. SUMMARY OF LITERATURE REVIEW: Posterior hemivertebra excision can be accomplished through a single posterior approach, and excellent correction and outcome may be achieved. MATERIALS AND METHODS: Forty patients with one fully segmented hemivertebra treated by posterior hemivertebra excision with pedicle screw instrumentation were retrospectively analyzed after a minimum follow-up of 2 years (range 2~7.7 years). The mean age at surgery was 15.9 years (range 2.6~37.9 years). Preoperative and postoperative standing radiographs were used to assess radiographic parameters. RESULTS: The average number of vertebrae in the major curve was 4.2 (range 3~8), and the average flexibility was 29% (range 8~59%). The average length of fusion was 3.5 segments (range 1~6). The number of fused vertebrae had a positive correlation with age at the index surgery (r=0.345, p<0.05). Mean preoperative scoliosis of 48+/-12degrees was corrected to a mean of 17+/-10degrees (65% correction), and mean preoperative kyphosis of 46+/-18degrees was corrected to a mean of 12+/-12degrees at the most recent follow-up. The compensatory curve had a mean of 25+/-10degrees preoperatively and spontaneously corrected to a mean of 8+/-8degrees (70% correction) at the most recent follow-up. The mean operating time was 233+/-81 min, with an average blood loss of 2904 ml. There was neither crankshaft phenomenon nor iatrogenic spinal stenosis in 6 patients under the age of 5 years after an average follow-up of 6 years. CONCLUSIONS: Posterior hemivertebra excision using pedicle screw instrumentation in congenital scoliosis due to a hemivertebra is a safe and effective procedure. Posterior hemivertebra excision at an early age may reduce the fusion length while avoiding the induction of iatrogenic spinal stenosis during follow-up.

The authors report a primary intramedullary spinal cord lymphoma in a 49-year-old man who presented with right arm pain, voiding difficulty and progressive walking difficulty. Preoperative cervical spinal CT and MRI studies were highly suggestive of spinal stenosis with compressive myelopathy but histopathological study of the specimen after surgery revealed spinal cord lymphoma. As no tumorous lesion was found other than the spinal cord, he was given 6000 rad of radiation under the diagnosis of primary CNS lymphoma. The neurologic deficits improved partially after the surgery but delete right arm pain persisted. One year later, follow up studies showed neither local nor systemic tumor recurrence.

PURPOSE: We wanted to evaluate the clinical significance of normal mammograms and normal sonograms in patients with palpable abnormalities of the breast. MATERIALS AND METHODS: From Apr 2003 to Feb 2005, 107 patients with 113 palpable abnormalities who had combined normal sonographic and normal mammographic findings were retrospectively studied. The evaluated parameters included age of the patients, the clinical referrals, the distribution of the locations of the palpable abnormalities, whether there was a past surgical history, the mammographic densities and the sonographic echo patterns (purely hyperechoic fibrous tissue, mixed fibroglandular breast tissue, predominantly isoechoic glandular tissue and isoechoic subcutaneous fat tissue) at the sites of clinical concern, whether there was a change in imaging and/or the physical examination results at follow-up, and whether there were biopsy results. This study period was chosen to allow a follow-up period of at least 12 months. RESULTS: The patients' ages ranged from 22 to 66 years (mean age: 48.8 years) and 62 (58%) of the 107 patients were between 41 and 50 years old (58%). The most common location of the palpable abnormalities was the upper outer portion of the breast (45%) and most of the mammographic densities were dense patterns (BI-RADS Type 3 or 4: 91%). Our cases showed similar distribution for all the types of sonographic echo patterns. 23 patients underwent biopsy; all the biopsy specimens were benign. For the 84 patients with 90 palpable abnormalities who were followed, there was no interval development of breast cancer in the areas of clinical concern. CONCLUSION: Our results suggest that we can follow up and prevent unnecessary biopsies in women with palpable abnormalities when both the mammography and ultrasonography show normal tissue, but this study was limited by its small sample size. Therefore, a larger study will be needed to better define the negative predictive value of combined normal sonographic and mammographic findings.

Hypertrophic osteoarthropathy(HOA) is a systemic disorder primary affecting the bones, joints, and soft tissues and characterized by several(or all) of the followings ; 1) Clubbing of digits, 2) Persistent new bone formation particulary involving long bones of the distal extremites, 3) Symmetric arthritis-like changes in the joints and periarticular tissue, most commonly the ankles, knees, wrist, and elbows, 4) Increased thickness of the subcutaneous soft tissues in the distal one-third of the arms and legs, and 5) Neurovascular changes of the hands and feet, including chronic erythema, paresthesis, and increase sweating. Most of cases of HOA are secondary to intrathoracic neoplasms, while the remaining few cases are secondary to other disease in the chest or elsewhere. We experienced a case of HOA in association with lung abscess in 26-yr-old male and reported with a review of literatures.
