PURPOSE: To investigate the timing of colostomy closure and the associated risk factors that affect the development of complication after colostomy closure. METHODS: We have reviewed and analyzed the results of 28 patients with colostomy closure at the Kwangju Christian Hospital from January 1993 to December 1997. We investigated to associated literatures on this subject for timing of colostomy closure, preparing a patient for colostomy closure, suture technique, wound management, underlying disease process related to the incidence of complication and experience of surgeons. RESULT: Wound infection developed in 4 patients (14.4%). Anastomotic leakage occurred in one patient (3.6%). Small bowel obstruction developed in two patients (7.2%). Overall incidence of complication was 25%. The incidence of complications in patients with trauma who underwent colostomy was 44.4% and patients without trauma, 15.8%. Complication rate was 16.6% for loop colostomies and 40% for end colostomies. The morbidity was 40% for colostomies on the left side, 18.7% for transverse colostomies, and 0% for colostomies (2 ileostomies) on the right side. The morbidity rate for closures within 6 weeks for the initial operation was 50%; for those within 6 to 12 weeks, 8.3%; and for those after 12 weeks, 16.6%. CONCLUSION: The optimal timing of closure varies from patient to patient, but closure within 6 weeks of the initial operation significantly increased the morbidity. Colostomies on the left side are associated with a higher morbidity rate than transverse colostomies or colostomies on the right side.

PURPOSE: The aim of this retrospective study was to evaluate the risk of local recurrence such as patients who were treated for Dukes stage B and C low rectal cancer by abdominoperineal resection (APR) or low anterior resection (LAR). METHODS: From 1985 to 1995, 81 patients with low rectal cancers which were within 3~8 cm from the anal verge were treated by curative resection, 38 by APR and 43 by LAR. The present study examined clinical and tumor characteristics, type of intervention as potential predictors of local recurrence. Retrospective data were analysed by univariate Chi-square tests. RESULTS: Local recurrence was diagnosed in 17 of 81 patients with a median follow-up period of 24 months. The local recurrence rate was 23.6% (9 of 38) after APR and 18.6% (8 of 43) after LAR. There was no difference in local recurrence between patients who had APR and LAR (P=0.58). Also we could not find any significant differences among age (< or =65 vs >65 years, P=0.53), sex (M vs F, P=0.57), sized of tumors (< or =5 vs >5 cm, P=0.32), distance from anal verge (< or =5 vs >5 cm, P=0.57), Dukes stage (B vs C, P=0.22), histological grade (well and moderate vs poorly, P=0.17), distance from distal resection margin (< or =2 vs >2 cm, P=0.35). CONCLUSIONS: The tumor factors such as Dukes' stage were more critical for pelvic recurrences than other patient factors.

PURPOSE: Traumatic rupture of the diaphragm is not easy to diagnose and often delayed. Delayed diagnosis of diaphragmatic rupture accompanied by higher chances of strangulation of herniated viscera which may result in higher morbility and mortality. The purpose of this study was to evaluate diagnostic accuracy of spiral CT, MRI and US for the diagnosis of diaphragmatic rupture in an animal model. MATERIALS AND METHODS: Small, medium, and large sized transabdominal diaphragmatic ruptures were surgically made in experimental rabbits and then followed up with spiral CT, MRI, and US at 1 day, 3 day, and 1 week after operation. RESULTS: US was superior to MRI or spiral CT in diagnosis of diaphragmatic rupture(P<0.05). The sensitivity and specificity were 94.4% and 92.9% for US, 54.0% and 85.7% for MRI, and 46.0% and 78.6% for spiral CT, respectively. The size of laceration was not related to diagnostic sensitivity in US. Sensitively of MRI and spiral CT increased as the size of laceration were larger, but no statistical significant was present(P>0.05). All experimental animals developed pleural effusion or hemothorax one day after operation. In acute phase. US and MRI were more sensitive than spiral CT in detecting diaphragmatic rupture. Spinal CT was more sensitive than US and MRI in delayed phase but without statistical significance(P>0.05) In the experimental rabbits with accompanying visceral hernia through the diaphragmatic defect, diagnostic accuracy was found equally high among three image modalities(P>0.05). CONCLUSION: This study indicates that US is the most accurate diagnostic method in detecting injury to the diaphragm in a rabbit model. The findings obtained in this experimental study can be applied to the diaphragmatic rupture of human being.

BACK GROUND: Our object is to conduct a questionnaire research with psychiatrists who have the experience of mental examination to suggest judgment standard for Not Guilty by Reason of Insanity and Guilty But Mentally Ill(diminished capacity). In addition, this study is expected to reduce the gap between the judgments on Not Guilty by Reason of Insanity and Guilty But Mentally Ill. METHODS: In making judgment on Not Guilty by Reason of Insanity and Guilty But Mentally Ill by experts, the questionnaire research is conducted through e-mail on the judgment standard on each mental disorders. According to the definition of mental disability, the item that shows higher percentage than the items of cognitional ability and volitional ability is considered as the requirement for judging mental disability. RESULTS: In all of 7 major mental disorders and disease groups, the symptoms and characteristics of the disease and the range of the influence of the symptom on the case were higher in 2-4 times than the induced standard (cognitional ability and volitional ability) from the legal and academic definitions of mental disability. CONCLUSIONS: The criteria for judging normal or mental disability is the cognitional ability and volitional ability. The criteria for judging Not Guilty by Reason of Insanity and Guilty But Mentally Ill in mental disability is the symptom and characteristics of the disease and the range of the influence of the symptom on the case.

PURPOSE: The aim of this prospective study was to evaluate the effect of metronidazole for wound infection by using intra-incisional infiltration before appendectomy. METHODS: From January to May 2000, 176 patients with acute appendicitis received appendectomy. All patients were randomly divided into two groups. Group I (n=50) was the treatment group and group II (n=126) was the control group. After anesthesizing the patients of group I, 7.5 mg/kg of metronidazole was injected into subcutaneous tissue and muscle. All patients of group I and II were given intravenous injection of cephalosporin and intravenous or intramuscular injection of aminoglycoside. RESULTS: In the 50 cases of group I, the rate of wound infection was 2% and the rate of wound infection in the 126 cases of group II was 4.8%. The rate of anaerobic bacteria of organisms cultured from wound of patients with infection was 0% in group I and 33% in group II. The statistical analysis using chi-square test was not significant (p=0.676) but the rate of wound infection was reduced, especially in infection caused by anaerobic bacteria. CONCLUSIONS: The rate of wound infection was not significant statistically but it was reduced after intra-incisional infiltration of metronidazole. Therefore we suggest that this method can be one of methods that reduce the rate of wound infection after appendectomy.

PURPOSE: Axium(TM) coils were developed to improve the durability of coil-embolized cerebral aneurysms by increasing packing density. The purpose of this prospective multicenter registry was to evaluate the safety and durability of Axium(TM) coils. MATERIALS AND METHODS: One hundred twenty-six patients with 135 aneurysms of < or = 15 mm in size underwent coil embolization using bare platinum coils, with Axium(TM) coils constituting over 50% of the total coil length. Immediate and short-term follow-up results were prospectively registered and retrospectively evaluated. RESULTS: Of the 135 aneurysms (83 unruptured and 52 ruptured), immediate post-embolization angiography revealed complete occlusion in 80 aneurysms (59.3%), neck remnants in 47 (34.8%), and incomplete occlusion in 8 (5.9%). The mean packing density was 42.8% (range, 9.5 - 90%) with Axium(TM) coil length constituting a mean of 87.9% of total coil length. The rate of procedure-related complications was 16.3%. Procedure-related permanent morbidity and mortality rates were 3.2% and 0.8%, respectively. Follow-up catheter or MR angiography, which was available in 101 aneurysms at 6 - 15 months (mean, 7.7 months), revealed stable or improved occlusion in 95 aneurysms and worsening in 6 aneurysms (5.9%). Lower packing density (< 30%) remained the only predictor for anatomical worsening on multivariable logistic regression analysis (P < 0.05). CONCLUSION: In this registry, Axium(TM) coils showed a relatively low rate of anatomical worsening on short-term follow-up imaging with an acceptable periprocedural safety profile compared to reports of other platinum coils. These results may warrant further study of long-term durability with Axium(TM) coils in larger populations.
