RESUMEN
BACKGROUND: The rupture of a splenic artery aneurysm (SAA) in pregnancy is an uncommon condition. However, it is associated with high mortality rates in pregnant women and fetuses even after surgical treatment. Though the endovascular treatment of SAAs is currently preferred as it can improve the outcomes even in emergent cases, the endovascular treatment of a ruptured SAA during pregnancy has not been reported until date. CASE SUMMARY: We report a case of a 33-year-old woman with the sudden onset of epigastric pain due to a ruptured SAA at the mid-portion of the splenic artery at 18 wk of pregnancy. After emergent initial resuscitation, the patient was diagnosed with a ruptured SAA through digital angiography. Immediately upon diagnosis, she underwent emergent endovascular embolization of the splenic artery for the rupture on the spot. Next, surgery was performed to remove the hematoma under stable conditions. Although the fetus was found to be dead during resuscitation, the woman recovered without complications and was discharged 15 d postoperatively. CONCLUSION: Endovascular treatment might be a valuable alternative to surgery/lead to safer surgery for selected pregnant patients with ruptured SAAs.
RESUMEN
We report the case of a 31-year-old man with superior mesenteric artery syndrome after reoperation due to postoperative complications from rectal cancer. Although initial total parenteral nutrition (TPN) therapy failed, he underwent endoscopy-assisted feeding tube placement without complications instead of surgery. After 2 weeks of dual feeding (enteral feeding and TPN), he improved, gaining 6 kg; and an oral diet was advanced.

BACKGROUND: Although skeletal muscle index (SMI) and radiodensity (SMD) are well-known prognostic factors, the clinical impact of the integrated measure, known as skeletal muscle gauge (SMG), has been limited in patients with colorectal cancer (CRC). PATIENTS AND METHODS: A total of 727 and 268 patients with CRC at two tertiary centers were included and allocated into the training and test sets, respectively. Preoperative slice computed tomography images of the third lumbar area were evaluated for SMI and SMD. SMG was calculated as SMI × SMD and expressed as an arbitrary unit (AU). The optimal cutoff SMG value was determined to maximize the overall survival (OS) difference between the groups with respect to sex in the training set. The multivariate Cox proportional hazard model evaluated the association of its clinical significance. RESULTS: With regard to SMG, 1640 and 1523 AU were identified as cutoff values for males and females, respectively. The patients with low SMG values showed significantly worse 5-year OS than those with high SMG values in the two datasets (both p < 0.001). In the multivariate analysis, low SMG was identified as an independent poor prognostic factor of OS in the training set (hazard ratio 2.18, 95% confidence interval 1.43-3.32, p < 0.001) and test set (hazard ratio 1.79, 95% confidence interval 1.07-3.00, p = 0.025), whereas SMI and SMD were not. CONCLUSION: SMG acts synergistically to improve its prognostic predictive accuracy as compared with SMI or SMD alone in patients with CRC. Additional research is warranted to define its significance in different ethnic groups.

BACKGROUND: Actinomycosis is a rare chronic invasive disease caused by Actinomyces spp. Although abdominopelvic actinomycosis, which involves the colon and the pelvic organs extensively, has been frequently reported, abdominopelvic actinomycosis presenting with colon perforation and hepatic involvement concurrently has yet to be reported. CASE PRESENTATION: A 55-year-old woman presented at the emergency room with squeezing epigastric pain. Palpation of the abdomen revealed a hard mass with no acute peritoneal signs. Vital signs were normal range except for tachycardia. Initial laboratory testing revealed leukocytosis, anemia, elevated C-reactive protein (CRP), hypoalbuminemia; and normal AST/ALT and BUN/creatinine. CT scan of the abdomen-pelvis revealed a microperforations of the sigmoid colon, abscess in the left lower quadrant and hepatic lesion. Furthermore, there was a large infiltrating conglomerated mass invading the urinary bladder, left adnexa, sigmoid, left inguinal canal and left pelvic wall area. Ultrasound revealed an intra-uterine device (IUD). All these findings initially raised a suspicion of malignancy such as advanced cancer of the colon with liver metastasis. Despite the rarity of the disease, actinomycosis were not excluded because of the IUD found on ultrasound. Parenteral antibiotics and percutaneous drainage of abdomen abscess as well as fasting with total parental nutrition were prescribed for sigmoid perforation and abscess. After 10 days of conservative treatment, no remarkable change was detected in conglomerated mass invading pelvis. Furthermore, the finding of newly developed mechanical small bowel obstruction warranted surgery. Exploratory laparotomy was performed for the removal of perforated colon, obstructive small bowel and organs involved and postoperative histology confirmed a diagnosis of colonic actinomycosis. The patient made an uneventful recovery and was started on a 6-month course of penicillin. CONCLUSIONS: Abdominopelvic actinomycosis presenting with colon perforation and hepatic involvement is extremely rare; however, it is clinically similar to advanced colon cancer with liver metastasis, therefore, complicating the preoperative diagnosis. A diagnosis of abdominopelvic actinomycosis should be considered in patients with a history of IUD and chronic abdominal pain, along with an abdominal mass or cutaneous abscess. If surgery is indicated, preoperative empirical antibiotic therapy for actinomycosis and frozen biopsy during surgery may be considered.

PURPOSE: Conventional laparoscopic appendectomy (CLA) has been considered the standard for the treatment of acute appendicitis. Recently, single incision laparoscopic appendectomy (SILA) has become an alternative option. There are few reports on the results of SILA performed by residents during the training period. The present study, we report our residents' experience. MATERIALS AND METHODS: We reviewed clinical characteristics and outcomes of 1005 patients who underwent appendectomy between October 2013 and April 2016. Every operation was performed by only residents. Clinical characteristics and operative outcomes between SILA and CLA group were reviewed after propensity score matching. RESULTS: SILA was used more frequently in younger patients (23.3 versus 36.4 years, P = .000), women (66.4% versus 45.9%, P = .000), and patients with lower body mass index (20.2 versus 22.9 kg/m2, P = .043). After propensity score matching, the rate of complicated appendicitis was lower (12.9% versus 15.5%, P = .573), and the mean operative time was slightly shorter in the SILA group than in the CLA group (56.68 versus 59.09 minutes, P = .068), although these differences were not statistically significant. There were no significant differences between the two groups in hospitalization period (2.7 versus 2.9 days, P = .380), the use of analgesics (2.0 versus 2.1 times, P = .128), and wound complication rate (10.3% versus 14.6%, P = .333). CONCLUSION: It is a safe and relatively easy procedure with an acceptable postoperative cosmetic outcome that can be incorporated into the routine surgical training.

RESUMEN
INTRODUCTION: Ischemic colitis (IC) is a disease with high postoperative morbidity and mortality. Knowledge of the risk factors for postoperative mortality could be helpful in clinical decision making and in optimizing postoperative treatment. METHODS: From a prospective database, we conducted a retrospective medical record review of 50 patients who underwent surgery for IC between 2003 and 2011 at our institution. We analyzed the causes and potential risk factors for early mortality after surgery for IC. RESULTS: The early postoperative mortality and morbidity rates were 30.0% (15/50) and 54% (27/50), respectively. The two most common causes of death were multi-organ failure (66.7%, 10/15) and fulminant septic shock (20.0%, 3/15). Univariate analysis showed that postoperative mortality was significantly associated with preoperative nephropathy, coronary artery disease, a previous history of cardiovascular surgery, an ASA score ≥ 4, surgical delay ≥ 3 days, preoperative hemodynamic instability, and use of pre- and intraoperative adrenergic vasopressors. In the multivariate analysis, a previous history of cardiovascular surgery (odds ratio [OR], 8.2; 95% confidence interval [CI], 1.2-56.5) and surgical delay ≥ 3 days (OR, 5.7; 95% CI, 1.2-27.9) were identified as independent risk factors for postoperative mortality. CONCLUSIONS: Because surgical delay is an avoidable determinant of early mortality, a high index of suspicion and early surgical intervention can increase survival. A routine postoperative evaluation for IC may be helpful in patients with a previous history of cardiovascular surgery.
RESUMEN
PURPOSE: To evaluate the effectiveness of endoscopic submucosal resection with a ligation device (ESMR-L) on histologic complete resection for the treatment of small rectal carcinoid tumors in comparison with the treatment with endoscopic mucosal resection (EMR) alone. METHODS: Thirty-five patients with small rectal carcinoid tumors were enrolled prospectively for ESMR-L, and we retrospectively reviewed 74 carcinoid tumor patients who underwent EMR. The comparison between ESMR-L and EMR groups was analyzed including endoscopic and histologic complete resection and complications after resection. We also evaluated the associations of histologic complete resection with clinical and procedure-related factors. RESULTS: The histologic complete resection rate was significantly higher in ESMR-L than in EMR (94.3% vs. 75.7%, P=0.019). In addition, the resection time was significantly shorter in ESMR-L than in EMR (4.16±1.48 min vs. 5.11±2.47 min, respectively, P=0.014). Moreover, previously biopsied rectal carcinoid tumors were significantly associated with histologic incomplete resection, especially in patients who underwent EMR (odds ratio, 6.28; 95% confidence interval, 1.92-20.58; P=0.002). CONCLUSIONS: Compared with EMR, ESMR-L is a safe and effective method for histologic complete resection of small rectal carcinoid tumors, especially in patients with previously biopsied carcinoid tumors.

PURPOSE: The aim of this study was to analyze oncologic outcomes after transanal local excision (LE) to ensure adequate surveillance of recurrence in order to treat with curative intent. METHODS: Between January 2000 and June 2009, 102 patients who underwent transanal LE for rectal adenocarcinoma were retrospectively reviewed. RESULTS: Of the 102 patients, 53 (52.0%) were male. The mean age was 57 ± 11 years. Postoperative pathologic examination revealed 93 cases (91.2%) of pathologic T stage (pT)1 and 9 cases (8.8%) of pT2. Forty-eight patients (47.1%) underwent adjuvant postoperative radiotherapy. The median follow-up interval was 60 months (range, 3 to 146 months). Seven (6.9%) out of 15 patients who suffered recurrence had locoregional recurrence, three (2.9%) had systemic recurrence and five (4.9%) had both systemic and locoregional recurrence. The latter five patients and two of the three patients with systemic recurrence died because of the disease recurrence. On the other hand, only one of the seven patients with locoregional recurrence died because of disease recurrence. CONCLUSION: Systemic recurrence after transanal LE results in fatal consequences. Therefore, not only is it important to identify ideal candidates for LE, but intensive postoperative surveillance is important as well to identify curable recurrence as soon as possible.
RESUMEN
Tristetraprolin (TTP) is an AU-rich element-binding protein that regulates mRNA stability. We previously showed that TTP acts as a negative regulator of VEGF gene expression in colon cancer cells. The p38 MAPK pathway is known to suppress the TTP activity. However, until now the signaling pathway to enhance TTP function is not well known. Here, we show that casein kinase 2 (CK2) enhances the TTP function in the regulation of the VEGF expression in colon cancer cells. CK2 increased TTP protein levels and enhanced VEGF mRNA decaying activity of TTP. TTP was not a direct target of CK2. Instead, CK2 increased the phosphorylation of MKP-1, which led to a decrease in the phosphorylation of p38 MAPK. Inhibition of MKP-1 by siRNA attenuated the increase in TTP function and the decrease of p38 phosphorylation induced by CK2α overexpression. TGF-ß1 increased the expressions of CK2 and TTP and the TTP function. The siRNA against CK2α or TTP reversed TGF-ß1-induced increases in the expression of CK2 and TTP and the TTP function. Our data suggest that CK2 enhances the protein level and activity of TTP via the modulation of the MKP-1-p38 MAPK signaling pathway and that TGF-ß1 enhances the activity of CK2.
