PURPOSE: Optimal management of colonoscopic perforation (CP) is controversial because early diagnosis and prompt management play critical roles in morbidity and mortality. Herein, we evaluate the outcomes and clinical characteristics of patients with CP according to treatment modality to help establish guidelines for managing CP. METHODS: Our retrospective analysis included 40 CP patients from January 1, 2003, to December 31, 2014. Patients with CP were categorized into 2 groups according to therapeutic modality: operation (surgery) and nonoperation (endo-luminal clip application or conservative treatment) groups. RESULTS: The postoperative morbidity rate was 40%, and no mortalities were noted. The incidence of abdominal pain and tenderness in patients who received only conservative management was significantly lower than in those who underwent surgery (P < 0.001 and P = 0.004, respectively). Patients tended to undergo surgery more often for diagnosis times longer than 24 hours and for diagnostic CPs. The mean hospital stays for the operation and nonoperation groups were 14.6 ± 7.77 and 5.9 ± 1.62 days, respectively (P < 0.001). Compared to the operation group, the nonoperation group began intake of liquid diets significantly earlier after perforation (3.8 ± 1.32 days vs. 5.6 ± 1.25 days, P < 0.001) and used antibiotics for a shorter duration (4.7 ± 1.29 days vs. 8.7 ± 2.23 days, P < 0.001). CONCLUSION: The time of diagnosis and the injury mechanism may be useful indications for conservative management. Nonoperative management, such as endo-luminal clip application, might be beneficial, when feasible, for the treatment of patients with CP.

BACKGROUND AND OBJECTIVE: The transsynaptic transfer of neurotropic viruses is an effective tool for tracing chains of connected neurons because the replication of virus in the recipient neurons after transfer amplifies the "tracer signal". The purpose of study was to identify the location of spinal nucleus of the accessory nerve and the central neural pathways using Bartha strain of Pseudorabies virus (PRV-Ba), as a transsynaptic tracer. MATERIALS AND METHODS: PRV-Ba was injected into the sternocleidomastoid muscle of a rat, and the localization of PRV-Ba in the rat spinal cord and CNS was identified with light microscopic immunohistochemistry using primary antibodies against the PRV-Ba. RESULTS: Sequential tracing of retrogradely labeled cells was done. The shapes of positive immunoreactive cells were mostly ovoid or polygonal, and were shown in the spinal nucleus of the accessory nerve, nucleus ambiguus, paraventricular nucleus, and the primary motor area of cerebral cortex. CONCLUSIONS: These results showed the location of spinal accessory nucleus and the central neural pathways of spinal accessory nerve using PRV-Ba.

PURPOSE: This study was to identify the relationship between perceived stress, anger expression, and level of depression in cancer patients. METHOD: A cross-sectional descriptive study design was used. Data was collected by questionnaires from 185 in- and out-patients who were diagnosed with cancer at 3 university hospitals and the National Cancer Center using Spielberger et al.'s Anger Expression Scale, Cohen, Kamarch & Mermelstein's Perceived Stress, and Derogatise's SCL-90. The data was analyzed using descriptive statistics, Pearson correlation coefficient, and stepwise multiple regression with SAS/PC. RESULT: The perceived stress in cancer patients indicated a significant positive correlation to anger-in(r=.288, p=.000), anger-out(r=.232, p=.001), and depression(r=.68, p=.000), but no significant correlation to anger-control. The anger-in of cancer patients showed a significant positive relationship to anger-out(r=.53, p=.000), and depression(r=.383, p=.000), but no significant correlation to anger-control. Anger-out showed a significantly negative correlation to anger-control(r=-.248, p=.001) and a positive correlation to depression(r=.240, p=.001). The most significant predictor which influenced depression in cancer patients was perceived stress, followed by anger-in and hobby, and these factors explained their depression with a variance of 54%. CONCLUSION: These results suggested that cancer patients with a high degree of perceived stress are likely to be high in anger-out and anger-in. Perceived stress and anger-in are major factors which affect depression in cancer patients.

PURPOSE: An individualized surveillance protocol based on stratified prognostic factors is needed for the early detection of recurrent disease. The aim of this study was to determine both the clinicopathological characteristics for early-recurring colorectal cancer and the impact on survival. METHODS: From January 1996 to September 2000, 1,504 patients with curatively resected colorectal cancer were recruited. The primary goal of this study was to evaluate the time interval until first loco-regional or distant recurrence, and the secondary goal was the last survival status. Early recurrence was defined as recurrence within the first 12 months postoperatively. Clinicopathologic data and preoperative CT records were reviewed. The follow-up period was over 48 months. RESULTS: The 5-year recurrence rate was 25.4%, and 39.5% of these were detected within the first 12 months postoperatively. In the multivariate analysis, the independent prognostic factors for early recurrence were cell differentiation (PD/MUC/SRC), lymphovascular invasion, and absence of adjuvant chemotherapy in stage III and curatively resected colorectal cancer in stage IV. Inaccurate interpretation by a low-quality CT scan resulted in a stage III cancer being understaged preoperatively. The 5-year overall survival rate according to the recurrent time interval was significantly different (early recurrence: 7.4% vs. late recurrence: 23.6%, P<0.05). The resection rate was similar in both groups (early recurrence: 22.7% vs. late recurrence: 27.6%, P=0.392). CONCLUSIONS: Colorectal cancer that recurred within 12 months showed more aggressive biologic behaviors and poor survival. Understaging caused by incomplete preoperative evaluation for disease extension may cause treatment failure.

PURPOSE: This article compares the results of various methods of inguinal hernia repair in adults. METHODS: We retrospectively reviewed the medical records of 473 patients over 20 years of age who received an inguinal hernia repair procedure between January 2000 and June 2007. We analyzed the patients' clinical factors and outcomes, dividing them into five groups according to method of repair: Bassini group, Lichtenstein group, mesh plug group, Prolene Hernia System (PHS) group, and laparoscopic group. RESULTS: The mean number of used analgesics was significantly smaller in the PHS group than in other groups (P<0.05, PHS group: 0.46, Bassini group: 1.55, Lichtenstein group: 1.20, mesh plug group: 0.82, laparoscopic group: 1.44). The mean operation time was significantly shorter in the PHS group than in the other groups (P<0.05, PHS group: 45.18 min, Bassini group: 59.85 min, Lichtenstein group: 68.20 min, mesh plug group: 66.73 min, laparoscopic group: 83.33 min). Finally, the mean postoperative hospital staywas significantly shorter in the PHS group than in the other groups (P<0.05, PHS group: 2.93 day, Bassini group: 4.96 day, Lichtenstein group: 4.17 day, mesh plug group: 4.01 day, laparoscopic group: 5.11 day). Out of five groups, there was onecase of postoperative recurrence in the Bassini group. CONCLUSION: Mesh PHS operation is a more preferred method of inguinal hernia repair in adults because it offers a lower postoperative pain, shorter operation time, shorter postoperative hospital stay.

BACKGROUND: The C-arm fluoroscope is known as the most important equipment in pain interventions. This study was conducted to investigate the completion rate of education on radiation safety, the knowledge of radiation exposure, the use of radiation protection, and so on. METHODS: Unsigned questionnaires were collected from the 27 pain physicians who applied for the final test to become an expert in pain medicine in 2011. The survey was composed of 12 questions about the position of the hospital, the kind of hospital, the use of C-arm fluoroscopy, radiation safety education, knowledge of annual permissible radiation dose, use of radiation protection, and efforts to reduce radiation exposure. RESULTS: In this study, although most respondents (93%) had used C-arm fluoroscopy, only 33% of the physicians completed radiation safety education. Even though nine (33%) had received education on radiation safety, none of the physicians knew the annual permissible radiation dose. In comparing the radiation safety education group and the no-education group, the rate of wearing radiation-protective glasses or goggles and the use of radiation badges or dosimeters were significantly higher in the education group. However, in the use of other protective equipment, knowledge of radiation safety, and efforts to reduce radiation exposure, there were no statistical differences between the two groups. CONCLUSIONS: The respondents knew very little about radiation safety and had low interest in their radiation exposure. To make the use of fluoroscopy safer, additional education, as well as attention to and knowledge of practices of radiation safety are required for pain physicians.

PURPOSE: As average life expectancies are prolonged, the elderly population is steadily increasing. The increasing number of elderly persons has been accompanied by cases of acute appendicitis in the elderly. In order to understand the clinical significance and to improve the treatment of elderly patients with appendicitis. we analyzed patients over 60 years of age with appendicitis. METHODS: We retrospectively reviewed the medical records of 268 patients over 60 years of age who were pathologically diagnosed with appendicitis. We analyzed the patients' clinicopathologic factors and outcomes, dividing them into 3 age groups: 60~69, 70~79, 80 and over. RESULTS: Of the 268 patients, there were 109 male and 159 female. The sex ratio was 1:1.46. The numbers of patients in each group were 169 (63.1%) in the 60-69 group, 73 (27.2%) in the 70~79 group, and 26 (9.7%) in the over 80 group. There was no difference in the leukocyte count and the time delay in surgical treatment between the groups. In the older groups, compared to the younger groups, there were more frequent paramedian and median incisions in the operation (P=0.02), a longer duration of postoperative admission (P=0.001) and starvation after the operation (P<0.001). In the pathologic findings, the gangrenous and abscess stages of appendicitis were more frequent in the older groups than in the younger groups (P<0.001). CONCLUSIONS: Early aggressive diagnostic intervention, such as ultrasound and CT, is essential in managing appendicitis in elderly patients who complain of vague abdominal pain.

Anorectal trauma associated with retained rectal foreign body is an infrequent clinical problem, but presents a challenge to physicians taking care of patients with this problem. We report a case of rectal foreign body (glass cup) extracted by laparotomy. A 49-year-old male with a history of alcoholism presented to the emergency room four days after inserting a glass cup into his rectum. He complained of vague anal pain and failure to pass flatus or stool for four days. He had attempted to extract the glass cup using various methods (digital, instrumental manipulation, enema), none of which was successful. Computed tomography revealed a glass cup lodged in the rectum, without complication. The patient was brought to the operating room, administered spinal anesthesia, and placed in lithotomy position after failure of extraction in the emergency room. Although the object was palpable, it could not be extracted either manually or by the use of forceps. We decided to perform an emergent laparotomy under general anesthesia. After the abdomen was opened, an attempt was made to milk the object toward the distal rectum. However, this proved to be impossible secondary to severe rectal mucosal edema. The glass cup was eventually extracted through performing a colotomy at the rectosigmoid junction, with primary repair. The patient's postoperative course was uneventful, and he was discharged on the eighth postoperative day.
