RESUMEN
Purpose@#Traumatic kidney injury can be treated surgically or nonsurgically. Nonsurgical treatment options include angiography, embolization, and conservative treatment. We aimed to identify factors that help in making clinical decisions on treatment plans for patients with traumatic kidney injury caused by blunt trauma. @*Methods@#The study included 377 patients aged ≥18 years with traumatic kidney injury caused by blunt abdominal trauma admitted to the emergency room of Wonju Severance Christian Hospital between January 2008 and July 2020. Medical records, laboratory test results, and computed tomography results were retrospectively reviewed. @*Results@#Multivariable logistic analysis showed diastolic blood pressure at admission and disruption of Gerota's fascia were significantly associated with surgical treatment, and that perinephric hematoma rim distance was the only significant indicator favoring embolization. Receiver operating characteristic curve analysis showed that angiography and embolization should be considered when hematoma size exceeds 2.97 cm. @*Conclusion@#When a patient with traumatic kidney injury due to blunt trauma visits an emergency room, even when vital signs are stable, Gerota’s fascia should be checked by computed tomography prior to deciding on surgical treatment, and angiographic embolization should be considered if perinephric hematoma rim distance exceeds 2.97 cm.

RESUMEN
For many years, developmental and physiological differences have been known to exist between anatomic segments of the colorectum. Because of different outcomes, prognoses, and clinical responses to chemotherapy, the distinction between right colon cancer (RCC) and left colon cancer (LCC) has gained attention. Furthermore, variations in the molecular features and gut microbiota between right and LCCs have recently been a hot research topic. CpG island methylator phenotype-high, microsatellite instability-high colorectal cancers are more likely to occur on the right side whereas tumors with chromosomal instability have been detected in approximately 75% of LCC patients and 30% of RCC patients. The mutation rates of oncogenes and tumor suppressor genes also differ between RCC and LCC patients. Biofilm is more abundant in RCC patients than LLC patients, as are Prevotella, Selenomonas, and Peptostreptococcus. Conversely, Fusobacterium, Escherichia/Shigella, and Leptotrichia are more abundant in LCC patients compared to RCC patients. Distinctive characteristics are apparent in terms of molecular features and gut microbiota between right and LCC. However, how or to what extent these differences influence diverging oncologic outcomes remains unclear. Further clinical and translational studies are needed to elucidate the causative relationship between primary tumor location and prognosis.

Although narcotic analgesics are potent releasers of histamine, IgE-mediated allergic reactions to these drugs are rare. Here we report the case of a 56-year-old male who suffered from chronic urticarial and analgesics-induced skin rashes. He visited our allergy clinic to determine alternative analgesics before undergoing surgery. A drug provocation test showed a positive reaction to aspirin, but negative reactions to acetaminophen and celecoxib. Despite careful attention to his drug regimen, during surgery he developed generalized urticaria and flushing. Skin tests of allergy to latex, lidocaine, propofol, rocuronium, flomoxef, meperidine, palonosetron, pyridostigmine, and fentanyl yielded negative results, except for the prick and intradermal tests with meperidine. Thus, this patient had both an aspirin/non-steroidal anti-inflammatory drugs idiosyncrasy and an IgE-mediated hypersensitivity to meperidine.

We report a case of synchronous multiple colon adenocarcinomas in a patient with neurofibromatosis type 1 (NF1). NF1 is an autosomal dominant inherited disorder and patients with NF1 have high risk for both benign and malignant tumors. However, adenocarcinomas involving the colon have rarely been reported in patients with NF1. A 61-year-old man was referred for generalized peritonitis due to descending colon perforation. Left hemicolectomy was performed and pathologic examination showed four adenocarcinomas. Peritoneal nodules were confirmed as metastatic adenocarcinoma (pT4N1M1). The patient also had clinical features compatible with NF1 such as cafe au lait macules, axillary freckles, neurofibromas across the body, and Lisch nodules. Upon review of the literature, colon adenocarcinoma in patients with NF1 tends to occur in males and relatively young age groups, and is associated with advanced tumor stages and multiple colon cancers. To improve treatment outcome, early colonoscopic surveillance should be considered in patients with NF1.

PURPOSE: To evaluate the influence of preoperative mechanical bowel preparation (MBP) based on the occurrence of anastomosis leakage, surgical site infection (SSI), and severity of surgical complication when performing elective colorectal surgery. MATERIALS AND METHODS: MBP and non-MBP patients were matched using propensity score. The outcomes were evaluated according to tumor location such as right- (n=84) and left-sided colon (n=50) and rectum (n=100). In the non-MBP group, patients with right-sided colon cancer did not receive any preparation, and patients with both left-sided colon and rectal cancers were given one rectal enema before surgery. RESULTS: In the right-sided colon surgery, there was no anastomosis leakage. SSI occurred in 2 (4.8%) and 4 patients (9.5%) in the non-MBP and MBP groups, respectively. In the left-sided colon cancer surgery, there was one anastomosis leakage (4.0%) in each group. SSI occurred in none in the rectal enema group and in 2 patients (8.0%) in the MBP group. In the rectal cancer surgery, there were 5 anastomosis leakages (10.0%) in the rectal enema group and 2 (4.0%) in the MBP group. SSI occurred in 3 patients (6.0%) in each groups. Severe surgical complications (Grade III, IV, or V) based on Dindo-Clavien classification, occurred in 7 patients (14.0%) in the rectal enema group and 1 patient (2.0%) in the MBP group (p=0.03). CONCLUSION: Right- and left-sided colon cancer surgery can be performed safely without MBP. In rectal cancer surgery, rectal enema only before surgery seems to be dangerous because of the higher rate of severe postoperative complications.

Because of insufficient number of donor hearts for cardiac transplantation, the use of implantable left ventricular assist device (LVAD) has been increasing as an alternative. During this procedure, the fundamental role of anesthesiologists would be to maintain stable hemodynamics. This report describes the anesthetic case of a 75-year-old man who underwent implantable LVAD placement as a destination therapy of his heart failure in Korea. The procedure and anesthesia were uneventful with transesophageal echocariographic guide. He moved to the ward on postoperative day 10 without fatal complication.

RESUMEN
BACKGROUND: Intrathecal labor analgesia using new local anesthetics such as ropivacaine or levobupivacaine becomes more popular by virtues of their safety and decreased motor weakness. However, the analgesic efficacy of the clinically effective intrathecal doses of these new local anesthetics combined with fentanyl has yet to be determined. METHODS: Sixty parturients who requested neuraxial analgesia in early active labor were randomly assigned to either ropivacaine (group R, n = 30) or levobupivacaine (group L, n = 30) group. Group R received 3 mg of intrathecal ropivacaine and the group L received 3 mg of intrathecal levobupivacaine mixed with 20 microg of fentanyl as part of a combined spinal-epidural (CSE) technique. The associated block parameters, such as pain scores, duration of analgesia, the highest levels of the sensory block and motor block scores 30 mins after the injection were compared between two groups. RESULTS: Intrathecal ropivacaine offered shorter analgesia (87 +/- 41 min vs. 122 +/- 56 min, P < 0.05) with lower sensory height (T8.5 vs. T6, P < 0.05) and led to lower incidence of complete analgesia (73 vs. 97%, P < 0.05) compared with intrathecal levobupivacaine. Although motor weakness was comparable in both groups, significantly weak perineal squeezing was noticed in Group L (7 of 30 parturients vs. 16 of 30, P < 0.05). CONCLUSIONS: Clinically relevant doses of intrathecal levobupivacaine in combination with fentanyl as part of a CSE technique provides more effective analgesia than equivalent doses of intrathecal ropivacaine in early labor, but is accompanied by slight motor weakness.

There are still debates regarding the appropriate primary treatment policy for asymptomatic primary colorectal lesions in cases of unresectable metastatic colorectal cancer. Even though there are patients with asymptomatic primary tumors when starting chemotherapy, those patients may still undergo surgery due to complications related to primary tumors in the middle of chemotherapy; therefore, controversy exists regarding surgical resection of primary colorectal lesions in cases where symptoms are absent when making a diagnosis. Thus, based on the published literature, we discuss opinions that prefer first-line surgery for primary tumors as well as opinions favoring first-line chemotherapy for treating unresectable synchronous metastatic colorectal cancer. Although the upfront chemotherapy including targeted agents is suggested as an effective treatment in recent years, the first line surgery has been a preferred treatment for decades. The first line surgery is beneficial to prolong the survival duration given the retrospective analysis of randomized trial data. So far, no prospective comparison study has only focused on the first-line treatment modality; thus, future clinical studies focusing on the survival duration and the quality of life should be performed as soon as possible. Furthermore, at this point, multidisciplinary team approaches would be helpful in finding the appropriate therapy. Regardless of symptoms, the performance status and the tumor burden should be taken into consideration as well. In case of surgical resection, minimally invasive surgery, such as laparoscopic surgery, is recommended.

OBJECTIVES: Medical complications are common and often serious in patients with eating disorders, however, little is known about complications in patients with bulimia nervosa. METHODS: We conducted a retrospectively investigation of clinical characteristics and hematologic, biochemical, hormonal, and bone density evaluations in 90 Korean women with bulimia nervosa together with 100 healthy Korean women of comparable ages. RESULTS: In patients with bulimia nervosa, 20% were anemic, 3.3% were hypokalemic, 14.4% had increased alanine aminotransferase, 24.4% were lower in serum protein, 8.8% were hypercholesterolemia, and 77.8% were hyperamylasemia. Osteopenia at any one site was identified in 26.7% of patients and the lowest-ever body mass index was the main determinant of bone mineral density in patients with bulimia nervosa. CONCLUSION: In this study, many features of medical findings reported in anorexia nervosa were found in bulimia nervosa, however, the findings in bulimia nervosa were milder form than in anorexia nervosa. Management of any physical abnormalities in bulimia nervosa should focus on correction of the eating disorder.

PURPOSE: Colorectal resection for elderly patients is associated with significant morbidity and mortality. It is still unclear whether or not laparoscopic colorectal resection (Lap CR) is indicated in elderly patients. The aim of this study is to evaluate the outcome of colonic surgery in elderly patients and to assess the feasibility and safety of laparoscopic colorectal surgery in elderly patients. METHODS: Patient characteristics and perioperative and pathologic data on 295 patients who underwent Lap CR for cancer from Jan. 2004 to Aug. 2011 were prospectively collected. Exclusion criteria were emergency and palliative by-pass surgery. Outcomes for elderly patients (> or =75 years) were compared with those of younger patients ( or =75 years, median age 79 years) showed a greater proportion off emale gender (52.6% vs. 37.0%, p=0.065) and American Society of Anesthesiologists score 2~3 (97.3% vs.42.0%, p<0.001). No differences in tumor location, median operative time, conversion rate, duration of hospital stay, and perioperative complications (23.7% vs. 30.0%, p=0.427) were observed between the two groups. Distributions of American Joint Committee on Cancer stages and number of harvested lymph nodes were comparable between groups. CONCLUSION: Although elderly patients are more likely to be affected by co morbidities, postoperative outcome in this group after Lap CR is comparable with that of younger patients. Use of Lap CR in elderly patients is safe, and is associated with a low morbidity. It should be also regarded as the optimal approach for very elderly patients.

PURPOSE: Wound infection after an ileostomy reversal is a common problem. To reduce wound-related complications, purse-string skin closure was introduced as an alternative to conventional linear skin closure. This study is designed to compare wound infection rates and operative outcomes between linear and purse-string skin closure after a loop ileostomy reversal. METHODS: Between December 2002 and October 2010, a total of 48 consecutive patients undergoing a loop ileostomy reversal were enrolled. Outcomes were compared between linear skin closure (group L, n = 30) and purse string closure (group P, n = 18). The operative technique for linear skin closure consisted of an elliptical incision around the stoma, with mobilization, and anastomosis of the ileum. The rectus fascia was repaired with interrupted sutures. Skin closure was performed with vertical mattress interrupted sutures. Purse-string skin closure consisted of a circumstomal incision around the ileostomy using the same procedures as used for the ileum. Fascial closure was identical to linear closure, but the circumstomal skin incision was approximated using a purse-string subcuticular suture (2-0 Polysorb). RESULTS: Between group L and P, there were no differences of age, gender, body mass index, and American Society of Anesthesiologists (ASA) scores. Original indication for ileostomy was 23 cases of malignancy (76.7%) in group L, and 13 cases of malignancy (77.2%) in group P. The median time duration from ileostomy to reversal was 4.0 months (range, 0.6 to 55.7 months) in group L and 4.1 months (range, 2.2 to 43.9 months) in group P. The median operative time was 103 minutes (range, 45 to 260 minutes) in group L and 100 minutes (range, 30 to 185 minutes) in group P. The median hospital stay was 11 days (range, 5 to 4 days) in group L and 7 days (range, 4 to 14 days) in group P (P < 0.001). Wound infection was found in 5 cases (16.7%) in group L and in one case (5.6%) in group L (P = 0.26). CONCLUSION: Based on this study, purse-string skin closure after a loop ileostomy reversal showed comparable outcomes, in terms of wound infection rates, to those of linear skin closure. Thus, purse-string skin closure could be a good alternative to the conventional linear closure.

PURPOSE: An abdominoperineal resection (APR) has a poor prognosis. However, limited studies about the prognostic factors in APR and the role of preoperative chemoradiotherapy (CRT) have been performed even though in rectal cancer, the application of preoperative CRT provides better local control compared to postoperative CRT. The aim of this study was to identify the prognostic factors and the impact of preoperative CRT in patients who undergo an APR. METHODS: A retrospective analysis was conducted with a total of 133 patients who underwent an APR, cT3, cT4, or cN(+) patients, for rectal cancer between January 1995 and October 2004. Fifty-one patients treated with preoperative CRT (Group 1) were compared with 82 APR patients treated with postoperative CRT (Group 2). Oncologic outcomes were compared between the two groups, and the clinicopathologic factors affecting the treatment outcomes were evaluated. RESULTS: The median follow-up period was 61.2 mo (range 6 to 194 mo). Circumferential margin (CRM) involvement was significantly associated with local recurrence (LR) and with disease-free survival in APR patients (P<0.001, P=0.011). The 5-yr LR rate was significantly lower in Group 1 than in Group 2 (P=0.013) in the univariate analysis, but no difference was noted in multivariate analysis (P=0.315). In Group 1, CRM involvement, tumor size, and lymph node metastasis were significantly lower than they were in Group 2 (P=0.043, P=0.003, P<0.001). CONCLUSION: For achieving adequate oncologic outcomes in APR patients, an adequate CRM should be acquired with an optimal operation. In addition, preoperative CRT would be helpful for high-risk APR patients with a threatening CRM margin, providing the benefit of tumor downstaging.

PURPOSE: This study was performed to evaluate whether age was a factor associated with oncological outcome for colon cancer patients who underwent a curative surgical resection. METHODS: A retrospective study of 2,125 colon cancer patients who underwent surgery between January 1989 to December 2004 was conducted. RESULTS: Of the 2,125 patients, 1,724 patients underwent a curative resection (R0). The patients with R0 were classified into three groups: group I (n=142) under 40 yr of age, group II (n=1,462) between 40 and 75 yr of age, and group III (n=120) over 75 yr of age. There were no significant differences in gender, tumor diameter, or postoperative complications among the groups. A history of hereditary colon cancer, advanced TNM stage (III, IV), and poorly- differentiated histology were more commonly found in group I. Adjuvant chemotherapy was administered less frequently in group III. In the survival analysis, the cancer-specific survival (CSS) and the disease-free survival (DFS) rates were not different between groups I and II. The CSS and the DFS rates of group III were significantly unfavorable compared with those of groups I and II. On the multivariate analysis, old age (group III), TNM stage, and preoperative CEA level were independent risk factors for CSS and DFS. CONCLUSION: In colon cancer patients, tailored approaches according to age, such as early screening in young adults with family history and proper patients selection for adjuvant treatment in old patients, could be needed.

AIMS: The left colon receives its arterial supply from the inferior mesenteric artery (IMA). The detailed anatomical understanding of IMA is important for sigmoid colon or rectal cancer surgery. The aim of this study is to investigate the vascular anatomy of the IMA by measuring the distance from the aortic bifurcation and the length of the IMA in autopsy cases. METHODS: 41 consecutive autopsy cases were enrolled prospectively. 29 cases were males and 12 females. Mean age was 47.7+/-15.6 with a range of 12 to 82 years. The distance from the aortic bifurcation is measured between the angle of abdominal aortic bifurcation and the inferior margin of the IMA. The length of the IMA is measured between the root of the IMA and the proximal border of the first branch of the IMA. Mann-Whitney U test, Pearson's correlation coefficient, and Spearman's rho were used for statistical analysis. RESULTS: The distance from the aortic bifurcation ranged from 3 to 6.3 cm with a mean of 4.4+/-0.71 cm. The length of the IMA ranged from 2.5 to 7 cm with a mean of 4+/-0.8 cm. The distance from the aortic bifurcation and the length of the IMA had no correlations with subject's height and weight. CONCLUSIONS: The vascular anatomy of the IMA in the general population is an important information for colorectal surgeon. Clear anatomical understanding of IMA may help perform oncologically safe colorectal surgery.

PURPOSE: Recently, magnetic resonance imaging (MRI) has become the preferred diagnostic tool for preoperative assessment of TNM staging and circumferential resection margin (CRM) in patients with rectal cancer. The aim of this study is to evaluate the accuracy of preoperative MR imaging in the prediction of T, N stage and CRM compared with pathologic results on whole- mount sections. METHODS: Thirty-five consecutive patients with rectal cancer were enrolled between Dec. 2005 and Apr. 2006. 1.5-T MR imaging, was performed, and pathologic results were investigated on whole-mount sections. The agreement between MR imaging and pathologic examination for the assessment of T, N stage and status of CRM were analyzed using kappa statistics. RESULTS: The accuracy of MR imaging compared with pathologic assessment of T stage was 82.9% (kappa=0.56), and that of N stage was 74.3% (kappa= 0.31). Of the MR imaging planes, the oblique axial plane showed the most accurate prediction of CRM, regardless of tumor position within the circumference of the rectum. The accuracy of MR imaging in the oblique axial plane for predicting the CRM was 81.0% (kappa=0.62) in anterior and posterior rectal tumors and 71.4% (kappa=0.43) in laterally located rectal tumors. With a different CRM criteria for the measured distance in MR imaging, the accuracy of the 2-mm CRM criterion was 77.1% (kappa=0.53). CONCLUSIONS: MR imaging in predicting T stage showed fair agreement according to kappa statistics. Of the MR imaging planes, the oblique axial plane provided the most accurate CRM information compared with pathologic examination. The actual measured distance of the CRM in MR imaging can be applied to the pathologic CRM.
