OBJECTIVE: This study is aimed to analyze the results of follow up after conization and to determine the value of repeat conization for treatment of cervical intraepithelial neoplasia (CIN) III. METHODS: Between March 1998 and February 2002, 241 women were underwent knife conization due to CIN III of the uterine cervix. After knife conization, follow-up visits were scheduled at 2 weeks interval during the first 3 months for cervical inspection only, then at every 3 months for the first year, every 6 months for the second year, and then annually for pelvic examination and Papanicolaou smears. Among 241 patients, 71 women were suspected of residual or recurrent lesions by cytology and colposcopy. Among 71 patients with residual or recurrent lesions, 37 patients received simple hysterectomy and 34 patients received repeat conization. RESULTS: The mean age of the patients was 36.4 years (range 27-64) and mean parity was 2 (range 0-6). The mean follow-up duration was 25.4 months (range 14-51) after conization. The results of repeat conization (n=34) were as follows; no residual lesion in 7 patients, CIN III in 15 patients, and lower grade neoplasia in 12 patients. Two patients were margin positive; 1 patient with CIN III, 1 patient with lower grade neoplasia. The outcomes of simple hysterectomy (n=37) were as follows; no residual lesion in 8 patients, CIN III in 18 patients, and lower grade neoplasia in 11 patients. Resection margin negative rates of repeat conization and simple hysterectomy were 94.1% and 100%, respectively (p>0.05). CONCLUSION: This study suggests that less invasive technique such as repeat conization might be an alternative method instead of hysterectomy in selected patients with recurrent or residual lesions who wish to preserve fertility.

PURPOSE: A laparoscopic appendectomy is now commonly performed. The push in recent years toward reducing the number of ports required to perform this surgery has led to the development of a single-port laparoscopic appendectomy (SPA). We compared postoperative pain after an SPA using a glove port with a percutaneous organ-holding device (group 1) with that of an SPA using a commercially-available multichannel single-port device (group 2). METHODS: Between March 2010 and July 2011, a retrospective study was conducted of a total of 77 patients who underwent an SPA by three surgeons at department of surgery, Kangbuk Samsung Medical Center. Thirty-eight patients received an SPA using a glove port with a percutaneous organ-holding device. The other 39 patients received an SPA using a commercially-available multichannel single port (Octo-Port or SILS Port). Operative details and postoperative outcomes were collected and evaluated. RESULTS: There were no differences in the mean operative times, times to pass gas, postoperative hospital stays, or cosmetic satisfaction scores between the two groups. The pain score in the first 24 hours after surgery was higher in group 2 than group 1 patients (P < 0.001). Furthermore, the trocar used in group 2 was more expensive than that used in group 1. CONCLUSION: An SPA using a glove port with a percutaneous organ-holding device was associated with a lower pain score during the first 24 hours after surgery because of the shorter fascia incision length and a cheaper cost than an SPA using a commercially-available multichannel single-port device.

Calcific tendinitis of hand and foot is rare and frequently misdiagnosed because of its rare incidence and its similar clinical presentation to other conditions such as infection. Awareness of the typical location as well as familiarity with the imaging findings is essential for making a correct diagnosis of this rare condition. We report four cases of calcific tendinitis of hand and foot, occurring in the flexor hallucis brevis, abductor digiti minimi, and abductor pollicis brevis.

OBJECTIVE: Although alcohol dependence is associated with a wide range of cognitive impairment, working memory function of alcohol dependence has not been well studied. The aim of this study was the assessment of working memory in alcohol dependence, the comparison of verbal and visuo-spatial working memory, and the examination of the correlations between working memory and clinical parameters. METHODS: A sample of 18 sober alcohol-dependent participants was compared with a sample of 19 controls on verbal and visuo-spatial working memory test using "2-back" system. RESULTS: Alcohol dependent participants showed the increased errors of verbal working memory. The amount of alcohol consumption during problem alcohol drinking period was correlated significantly with false positive error of verbal working memory. CONCLUSION: These results demonstrated that alcohol dependence impairs verbal working memory despite no impairment of intelligence. This study suggested the relationship between verbal working memory impairment and the amount of alcohol consumption.

BACKGROUND: Multiple system atrophy (MSA) and idiopathic Parkinson's disease (IPD) are two common neurodegenerative disorders presenting with parkinsonism. Since a brain MRI study is an available method for differentiating MSA from IPD, we tried to find further values of brain MRI studies in differentiating MSA from IPD. METHODS: We measured anteroposterior and transverse diameters (AD and TD, respectively) of the brain stem of T2-weighted axial images. We graded the severity of atrophy (grade 0: none; grade 1: mild; grade 2: moderate; and grade 3: severe) of cerebellar vermis and hemispheres on the midsagittal and parasagittal planes. RESULTS: There were 36 patients with probable MSA and 40 patients with IPD. We calculated a parameter multiplying AD of the midbrain by TD of the midbrain. The mean of the AD x TD of the midbrain was 1007.5 +/- 161.8 mm2 in patients with MSA, and it was significantly smaller than that of those with IPD (1113.3 +/- 118.7 mm2). When the cut off value was decided as 1050 mm2, the sensitivity of the parameter for the diagnosis of MSA was 83.3% and specificity was 80%. The frequency of cerebellar atrophy was 72.2% in patients with MSA, and it was significantly higher than that of those with IPD (37.5%). CONCLUSIONS: Measurements of the brain stem, particularly the midbrain, and cerebellum areas on brain MRI are helpful methods for the differential diagnosis of patients with MSA from those with IPD.

PURPOSE: BRAF mutation and expression of extracellular signal regulated kinase (ERK) are linked with colorectal carcinogenesis through the serrated pathway. BRAF and ERK1/2 play important roles in the activation of mitogen-activated protein (MAP) kinase signaling pathways. The present study investigated the clinicopathologic outcomes of BRAF mutation and ERK1/2 expression in patients with colorectal cancer (CRC) and the possibility of using them as prognostic indicators. METHODS: Dual-priming oligonucleotide-based multiplex polymerase chain reaction for BRAF(V600E) mutation and immunohistochemical analysis of ERK1/2 were performed using 65 formalin-fixed, paraffin-embedded samples from patients with CRC. We analyzed the dependences of the clinicopathologic features on BRAF mutation and ERK1/2 expression. RESULTS: Out of 65 samples from CRC patients, BRAF mutation was detected in 3 (4.6%). The 3 patients with BRAF mutation presented with T3 CRC with lymph node metastasis (stage III) showing moderately or poorly differentiated histology. ERK1 and ERK2 were positively detected in 73.8% and 15.4% of the patients with CRC, respectively. ERK1 expression was significantly correlated with lymph node metastasis (P = 0.049). ERK2 expression was significantly correlated with tumor emboli (P < 0.05), tumor invasion (P = 0.035), lymph node metastasis (P = 0.017), and stage (P = 0.02). CONCLUSION: BRAF mutation and ERK1/2 expression may be associated with advanced or more aggressive CRC. These molecular markers might play prognostic roles in CRC developed through the serrated pathway.

PURPOSE: Acute appendicitis is one of the most common surgical emergencies worldwide. Laparoscopic appendectomy (LA) is being accepted as the 'gold standard' surgery for simple acute appendicitis over open appendectomy (OA); however, for complicated appendicitis, no consensus has been reached with regard to which produces better outcomes. METHODS: We analyzed the data of patients who were diagnosed as complicated appendicitis, older than 18 years old, and underwent LA or OA from January 2008 to December 2012. A total of 2,173 patients had acute appendicitis during this period and 461 (21.2%) of them had complicated appendicitis; 335 patients were finally enrolled and divided into LA (280), OA (49), and Converted to open Appendectomy (CA) groups (6), respectively. Age, sex, preoperative WBC, operating time, stapler usage, time to diet and discharge, total cost and complication among the three groups were analyzed. RESULTS: No significant differences were observed in sex, age, history of abdominal surgery, preoperative WBC, and total cost. Shorter operating time (62.3+/-30.0 vs 87.3+/-40.2, p=0.000), shorter time to diet (2.7+/-2.2 vs 3.7+/-1.6, p=0.001), shorter postoperative stay (4.8+/-2.6 vs 7.1+/-2.5, p=0.000), shorter duration of pain (3.4+/-1.7 vs 5.6+/-2.8, p=0.000), and less frequent usage of pain killer (68.2% vs 89.1%, p<.001) were observed in the laparoscopic group. Complication rate was significantly lower in the LA group (4.6% vs 18.4%, p=0.002). CONCLUSION: Results of this study provide clinical evidence that laparoscopic surgery is a feasible and safe surgical modality for complicated appendicitis. Conduct of more reliable, large scaled, randomized prospective study will be necessary in order to prove the superiority of laparoscopic surgery for complicated appendicitis.

Journal of the Korean Surgical Society 2011;81(3):163-168
PURPOSE: Titanium silicate (TS)-1 chemotherapy has been widely used against gastric cancer in Japan. The aim of the present study was to assess the efficacy and hematological safety of TS-1 as treatment for advanced and recurrent gastric cancer. METHODS: From September 2006 to February 2011, 51 advanced or recurrent gastric cancers were treated with TS-1. One course of treatment consisted of 40, 50, or 60 mg/m2 of TS-1 twice a day for 28 days, followed by withdrawal for two weeks. The primary end point was progression-free survival (PFS), and the secondary end point was overall survival (OS). RESULTS: The disease control rate was 39.2% (complete response, 0/51; partial response, 6/51; stable disease, 14/51; progressive disease, 23/51; not evaluable, 8/51). The median PFS was 4.0 months (95% confidence interval [CI], 2.2 to 5.7); the median PFS of the advanced group was 6.0 months (95% CI, 2.8 to 9.1), and the median PFS of the recurrent group was 3.0 months (95% CI, 1.8 to 4.1). The median OS was 11.0 months (95% CI, 6.3 to 15.6); the median OS of the advanced group was 10.0 months (95% CI, 4.9 to 15.0), and the median OS of the recurrent group was 14.0 months (95% CI, 4.1 to 23.8). Grade 3 or 4 hematological toxicity occurred in three patients (5.9%), anemia occurred in two patients (3.9%), and thrombocytopenia occurred in one patient (2%). CONCLUSION: TS-1 chemotherapy was safe and effective, with relatively long PFS and OS in patients with advanced and recurrent gastric cancers.

Transesophageal echocardiography(TEE) is a new acoustic window to the cardiac structures and great vessels via retrocardiac esophagus. Because of the close relation between the esophagus and the heart, higher transducer frequencies can be applied, therefore leading to improved resolution and more accurate images than transthoracic echocardiography. We describe our experience with the first 353 awake patients. The procedure was well tolerated by the patients and associated with no major complications, within examination 10 to 20 minutes. Clinical diseases which appear to be suited for TEE includes 1) evaluation of native valve diseases, particulary mitral valve, pathologic valvular abnormalities and color Doppler regurgitant flows ; 2) assesment of prosthetic heart valves to better define malfunction and important pathologic associations ; 3) congenital heart disease, particularly atrial septal defect ; 4) endocarditis and detection of vegetations and complications ; 5) detection of thrombus and tumors, size, location, morphology, stalk ; and 6) aortic pathology including atherosclerosis, aneurysm and dissection. We conclude that transesophageal echocardiography is a new imaging technique that is rapidly evolving into a major tool for general cardiac imaging in a variety pathologic conditions and is a safe and useful tool in patients. Future advances in probe technology will continue to expand its applications.

PURPOSE: Continued efforts to reduce the invasiveness of conventional cholecystectomy techniques have resulted in the development of single-incision cholecystectomy. However, a single-port approach has significant limitations associated with proper triangulation and instrument crowding and collisions. Although the da Vinci Single-Site robotic system has been proposed to overcome these problems, objective evidence of the feasibility and ergonomics of single-incision robotic cholecystectomy (SIRC) is insufficient. Therefore, the present study aimed to evaluate the feasibility and efficacy of SIRC by using objective data obtained from consecutive patients who underwent surgery with the single-incision robotic platform performed by a single surgeon. METHODS: Forty patients who underwent SIRC between August 2014 and December 2015 were identified. Demographic, perioperative, and postoperative data were collected retrospectively. RESULTS: The mean docking time was 10.82±4.85 min (range, 4~30 min). The mean console time was 49.63±10.82 min (range, 24~90 min). None of the patients required an additional laparoscopic arm, an additional robotic arm, or conversion to conventional laparoscopic cholecystectomy. CONCLUSION: SIRC can provide a safe operative procedure, good operative results, and high patient satisfaction, and cause less surgeon fatigue. Therefore, our study results indicate that SIRC is feasible and favorable for both patients and physicians.
