RESUMO
BACKGROUND: The aim of this study was to compare the 1 year incidence of Petersen's hernia between individuals who were treated with the jejunal mesentery fixing (Mefix) method and those with the closure of Petersen's space method. MATERIAL AND METHODS: We retrospectively collected clinical data of patients who underwent gastrectomy for gastric cancers with the closure of Petersen's space defect (N = 49) and Mefix (N = 26). The Mefix method was performed by fixing the jejunal mesentery (jejunojejunostomy below 30 cm) to the transverse mesocolon using nonabsorbable barbed sutures. RESULTS: The procedure time for mesentery fixing (3.7 ± 1.1 mins) was significantly shorter than that for Petersen's space closure (7.5 ± 1.5 mins) (p < .001) although the operation times were similar between the two groups. There was no incidence of Petersen's hernias postoperatively in both groups. One case of reoperation was reported in the closure group due to small bowel obstruction by kinking of the jejunojejunostomy. CONCLUSION: We found no occurrence of Petersen's hernias postoperatively in either group. We also found that the Mefix method was faster and easier to perform than the closure method. The Mefix method is an excellent alternative method to prevent the occurrence of Petersen's hernia after B-II or Roux-en-Y reconstruction.

OBJECTIVE. This retrospective study aimed to investigate the capability of the already-proposed thyroid imaging reporting and data system for detecting diffuse thyroid disease (DTD-TIRADS) on ultrasound (US) by assessing interobserver agreement and diagnostic performance. MATERIALS AND METHODS. A total of 180 patients who underwent thyroid US before thyroid surgery were included. Three radiologists blinded to the pathologic and serologic data independently categorized the US features according to a four-category DTD-TIRADS classification system. On the basis of the pathologic results of thyroid parenchyma, diagnostic performance values were calculated using ROC curve analyses. Interobserver agreements of each US feature and DTD-TIRADS category among the three radiologists were also assessed. RESULTS. Of the 180 patients, 143 (79.4%) had normal thyroid parenchyma and 37 (20.6%) had diffuse thyroid disease (DTD). The areas under the ROC curve for DTD were not significantly different among the three radiologists: 0.876 (95% CI, 0.819-0.920) for radiologist 1, 0.883 (95% CI, 0.827-0.926) for radiologist 2, and 0.861 (95% CI, 0.801-0.908) for radiologist 3 (p > .05). The cutoff for the diagnosis of DTD was category III DTD-TIRADS. The sensitivity, specificity, and accuracy of DTD-TIRADS for detecting DTD were 86.5%, 81.1%, and 82.2% for radiologist 1; 86.5%, 83.2%, and 83.9% for radiologist 2; and 83.8%, 82.5%, and 82.8% for radiologist 3, respectively. Interobserver agreement of DTD-TIRADS categorization was almost perfect (κ = 0.81). CONCLUSION. DTD-TIRADS has high diagnostic performance and almost-perfect interobserver agreement. Thus, DTD-TIRADS can be considered to be an effective classification system for diagnosing DTD.

BACKGROUND: The aim of this multicenter cohort study was to compare the clinical courses between open and laparoscopic Petersen's hernia (PH) reduction. METHOD: We retrospectively collected the clinical data of patients who underwent PH repair surgery after gastrectomy for gastric cancer from 2015-2018. Forty patients underwent PH reduction operations that were performed by six surgeons at four hospitals. Among the 40 patients, 15 underwent laparoscopic PH reduction (LPH), and 25 underwent open PH reduction (OPH), including 4 patients who underwent LPH but required conversion to OPH. RESULTS: We compared the clinical factors between the LPH and OPH groups. In the clinical course, we found no differences in operation times or intraoperative bowel injury, morbidity, or mortality rates between the two groups (p > 0.05). However, the number of days on a soft fluid diet (OPH vs. LPH; 5.8 vs. 3.7 days, p = 0.03) and length of hospital stay (12.6 vs. 8.2 days, p = 0.04) were significantly less in the LPH group than the OPH group. Regarding postoperative complications, the OPH group had a case of pneumonia and sepsis with multi-organ failure, which resulted in mortality. In the LPH group, one patient experienced recurrence and required reoperation for PH. CONCLUSION: Laparoscopic PH reduction was associated with a faster postoperative recovery period than open PH reduction, with a similar incidence of complications. The laparoscopic approach should be considered an appropriate strategy for PH reduction in selected cases.

BACKGROUND: We aimed to identify whether neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are more useful predictors after initial intention to treat than at the time of diagnosis. METHODS: We collected the medical data of 533 patients. The results of the peripheral blood sampling before the primary treatments were labeled as initial cohort, and those obtained between 24 and 36 months after initial treatment were defined as the 2nd cohort. Delayed metastasis has been defined as distant metastasis 2 years after treatment, and survival outcome was estimated and compared across groups. RESULTS: Median follow-up duration was 74 months (24-162 months), and 53 patients experienced delayed metastasis. In univariate analysis, metastasis-free survival, patient age at diagnosis, tumor size, axillary lymph node metastasis, HER-2 status, initial NLR and PLR, and 2nd NLR and PLR were found to be significantly associated with delayed metastasis. However, in multivariate analysis, only the 2nd NLR and PLR were found to be significantly associated with delayed metastasis, excluding initial NLR and PLR. Metastasis-free survival was analyzed through the pattern changes of NLR or PLR. The results revealed that patients with continued low NLR and PLR values at pre- and post-treatment (low initial values and 2nd values) showed a significantly better prognosis than those with a change in value or continued high NLR and PLR. CONCLUSIONS: We identified that patients with persistent high NLR and PLR after initial treatment have significant worse prognosis in terms of late metastasis. Therefore, these results suggest that NLR and PLR are more useful in predicting prognosis post-treatment.

This review aimed to examine the existing evidence about interventions proposed for the treatment of clinical chorioamnionitis, with the goal of developing an evidence-based contemporary approach for the management of this condition. Most trials that assessed the use of antibiotics in clinical chorioamnionitis included patients with a gestational age of ≥34 weeks and in labor. The first-line antimicrobial regimen for the treatment of clinical chorioamnionitis is ampicillin combined with gentamicin, which should be initiated during the intrapartum period. In the event of a cesarean delivery, patients should receive clindamycin at the time of umbilical cord clamping. The administration of additional antibiotic therapy does not appear to be necessary after vaginal or cesarean delivery. However, if postdelivery antibiotics are prescribed, there is support for the administration of an additional dose. Patients can receive antipyretic agents, mainly acetaminophen, even though there is no clear evidence of their benefits. Current evidence suggests that the administration of antenatal corticosteroids for fetal lung maturation and of magnesium sulfate for fetal neuroprotection to patients with clinical chorioamnionitis between 24 0/7 and 33 6/7 weeks of gestation, and possibly between 23 0/7 and 23 6/7 weeks of gestation, has an overall beneficial effect on the infant. However, delivery should not be delayed to complete the full course of corticosteroids and magnesium sulfate. Once the diagnosis of clinical chorioamnionitis has been established, delivery should be considered, regardless of the gestational age. Vaginal delivery is the safer option and cesarean delivery should be reserved for standard obstetrical indications. The time interval between the diagnosis of clinical chorioamnionitis and delivery is not related to most adverse maternal and neonatal outcomes. Patients may require a higher dose of oxytocin to achieve adequate uterine activity or greater uterine activity to effect a given change in cervical dilation. The benefit of using continuous electronic fetal heart rate monitoring in these patients is unclear. We identified the following promising interventions for the management of clinical chorioamnionitis: (1) an antibiotic regimen including ceftriaxone, clarithromycin, and metronidazole that provides coverage against the most commonly identified microorganisms in patients with clinical chorioamnionitis; (2) vaginal cleansing with antiseptic solutions before cesarean delivery with the aim of decreasing the risk of endometritis and, possibly, postoperative wound infection; and (3) antenatal administration of N-acetylcysteine, an antioxidant and antiinflammatory agent, to reduce neonatal morbidity and mortality. Well-powered randomized controlled trials are needed to assess these interventions in patients with clinical chorioamnionitis.

OBJECTIVES: To evaluate the predictive value of virtual monoenergetic images (VMIs) by assessing tumor conspicuity on dual-layer spectral detector CT (SDCT) and correlate tumor conspicuity on VMI with prognostic biomarkers in patients with breast cancer. METHODS: Sixty-four patients underwent arterial phase and 90-s delayed phase dual-layer SDCT. A retrospective tumor conspicuity analysis of 14 benign tumors and 65 breast cancers was performed using conventional images (CIs) and VMI at 40 keV (VMI40) on arterial and delayed phase scans (CIART, VMI40ART, CIDE, VMI40DE). Mean Hounsfield units (HU) of tumors were measured on VMI40ART and VMI40DE. A receiver operating characteristic (ROC) curve analysis was performed to compare diagnostic accuracy between image sets. Estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and Ki67 levels were evaluated using histopathology. Correlations between VMI analyses and histological characteristics of cancers were analyzed. RESULTS: Cancers on VMI40 had a significantly higher conspicuity score and mean HU than benign tumors (p < 0.001). VMI40DE showed the highest conspicuity for cancers (mean, 3.79) and the greatest area under the ROC curve (0.817; 95% confidence interval 0.745-0.889). VMI40DE yielded significantly higher mean HU for cancers than VMI40ART (p < 0.001). The conspicuity score and mean HU on VMI40ART were significantly higher in cancers with ER negativity, PR negativity, and Ki67 positivity (p < 0.05). CONCLUSIONS: VMI40DE may be useful in the diagnosis of breast cancers due to higher tumor conspicuity and better enhancement than VMI40ART. VMI40ART may be beneficial for the prediction of poor breast cancer prognoses. KEY POINTS: ⢠VMI40 improved conspicuity of breast cancer than CI. ⢠VMI40DEyielded higher diagnostic performance of breast cancer than VMI40ART. ⢠VMI40ARThas an additional benefit in terms of prognosis prediction in patients with breast cancers.

BACKGROUND: Anastomotic complications such as leaks, bleeding, and stricture remain the most serious complications of surgery for gastric cancer. No perfect method exists for an accurate and reliable prevention of these complications. This study investigated the safety and efficacy of post-anastomotic intraoperative endoscopy (PAIOE) for avoidance of early anastomotic complications during gastrectomy in gastric cancer. METHODS: This retrospective case-control study enrolled patients from a tertiary care, academic medical center. Routine PAIOE was performed on 319 patients undergoing gastrectomy for gastric cancer between 2015 and 2016. As controls, without PAIOE 270 patients from 2013 to 2014 were used for comparison. Early anastomotic complications and outcomes after PAIOE were determined. RESULTS: Although there were no differences between the PAIOE and non-PAIOE group in terms of overall complication rates (20.1% vs 26.7%; P > 0.05), there were fewer complications related to anastomosis (3.4% vs 8.9%; P < 0.01) in the PAIOE group. The PAIOE group had rates of 2.5% for anastomotic leakage, 0.9% for intra-luminal bleeding, and 0% for anastomotic stenosis, while the non-PAIOE group exhibited rates of 5.6%, 2.6%, and 0.7%, respectively. Thirty-one abnormalities were detected in 26 PAIOE patients (9.71%) (20 venous bleeding, 7 mucosal tearing, 2 air leaks, 1 arterial bleeding, and 1 anastomotic stricture). All abnormalities were corrected by proper interventions (13 reinforced additional suture, 13 endoscopic hemostasis, and 2 re-anastomosis). There were no morbidities associated with PAIOE. CONCLUSIONS: PAIOE appears to be a safe and reliable procedure to evaluate the stability of gastrointestinal anastomosis for gastric cancer patients. Further data collection and a well-designed prospective study are needed to confirm the validity of PAIOE.

BACKGROUND: In our previous study, transumbilical endoscopic submucosal dissection (TU-ESD) was revealed to be feasible, but delayed gastric perforation was observed in 30% of ESD sites. In this study, we aimed to verify locations at which it is feasible to perform TU-ESD in the upper gastric body and to demonstrate the safety of TU-ESD in single-basin lymph node dissection (SBLND). METHODS: In vitro, TU-ESD was performed at three lesion sites (anterior wall, AW; posterior wall, PW; and lesser curvature, LC) in each porcine stomach using an EASIE-R tray (cases = 10). In vivo, TU-ESD was performed with SBLND in 9 pigs. Seven days after the operation, the pigs were sacrificed and examined. RESULTS: In the in vitro feasibility study, the TU-ESD time was significantly faster in the PW group (5.9 ± 2.0 min) than in the LC group (8.5 ± 1.5 min) (p < 0.05) in all 10 cases. In the in vivo survival study, TU-ESD with SBLND was successfully performed without any complications (N = 9). There were no cases of delayed perforation, and healing ulcers were found in all pigs 7 days after the operation. Ulcer size (5.2 ± 3.5 cm2) was approximately 36% smaller than that observed at the ESD operation site (8.1 ± 1.9 cm2) (p = 0.05). Epithelialization in the margin and healing of the gastric ulcers were confirmed by microscopy. CONCLUSIONS: TU-ESD with SBLND is a feasible and safe method. The upper posterior gastric body could be the most feasible location for performing TU-ESD, perhaps because of the difference in the subcutaneous dissection time.

Background Normal development of the human placenta, referred to as villous tree maturation, entails formation of the vasculosyncytial membranes. These structures develop by the approximation of syncytiotrophoblasts with the villous capillary endothelium and constitute the most efficient sites of gaseous exchange in the placenta. Defective maturation of the villous tree can lead to deficient vasculosyncytial membranes, implicated in the high incidence of hypoxic complications. Hypoxia, in turn, can stimulate production of erythropoietin, whereby increased fetal plasma or amniotic fluid concentrations of this hormone reflect fetal hypoxemia. The current study was undertaken to determine whether delayed villous maturation is associated with changes in amniotic fluid erythropoietin concentrations. Methods Placental histologic examination was performed using hematoxylin and eosin. Subsequent to histologic assessment of delayed villous maturation, the diagnosis was confirmed with CD-15 immunohistochemistry. The controls (n = 61) were pregnancies without villous maturation abnormalities, and cases (n = 5) were pregnancies with delayed villous maturation. Amniotic fluid erythropoietin concentrations were measured using a specific immunoassay. Results Concentrations of erythropoietin in the amniotic fluid (1) of controls were less than the limit of detection and (2) of cases with delayed villous maturation were significantly higher than those of controls (P-value = 0.048). Conclusion Delayed villous maturation is associated with higher concentrations of amniotic fluid erythropoietin.

BACKGROUND: While extended cholecystectomy is recommended for T2 gallbladder cancer (GBC), the role of hepatic resection for T2 GBC is unclear. This study aimed to identify the necessity of hepatic resection in patients with T2 GBC. METHODS: Data of 81 patients with histopathologically proven T2 GBC who underwent surgical resection between January 1999 and December 2017 were enrolled from a retrospective database. Of these, 36 patients had peritoneal-side (T2a) tumors and 45 had hepatic-side (T2b) tumors. To identify the optimal surgical management method, T2 GBC patients were classified into the hepatic resection group (n = 44, T2a/T2b = 20/24) and non-hepatic resection group (n = 37, T2a/T2b = 16/21). The recurrence pattern and role of hepatic resection for T2 GBC were then investigated. RESULTS: Mean age of the patients was 69 (range 36-88) years, and the male-to-female ratio was 42:39 (male, 51.9%; female, 48.1%). Hepatic-side GBC had a higher rate of recurrence than peritoneal-side GBC (44.4% vs. 8.3%, p = 0.006). The most common type of recurrence in T2a GBC was para-aortic lymph node recurrence (n = 2, 5.6%); the most common types of recurrence in T2b GBC were para-aortic lymph node recurrence (n = 7, 15.6%) and intrahepatic metastasis (n = 6, 13.3%). Hepatic-side GBC patients had worse survival outcomes than peritoneal-side GBC patients (76.0% vs. 96.6%, p = 0.041). Hepatic resection had no significant treatment effect in T2 GBC patients (p = 0.272). Multivariate analysis showed that lymph node metastasis was the only significant prognostic factor (p = 0.002). CONCLUSIONS: Hepatic resection is not essential for curative treatment in T2 GBC, and more systemic treatments are needed for GBC patients, particularly for those with T2b GBC.

Objectives To investigate mechanisms of in utero death in normally formed fetuses by measuring amniotic fluid (AF) biomarkers for hypoxia (erythropoietin [EPO]), myocardial damage (cardiac troponin I [cTnI]) and brain injury (glial fibrillary acidic protein [GFAP]), correlated with risk factors for fetal death and placental histopathology. Methods This retrospective, observational cohort study included intrauterine deaths with transabdominal amniocentesis prior to induction of labor. Women with a normal pregnancy and an indicated amniocentesis at term were randomly selected as controls. AF was assayed for EPO, cTnI and GFAP using commercial immunoassays. Placental histopathology was reviewed, and CD15-immunohistochemistry was used. Analyte concentrations >90th centile for controls were considered "raised". Raised AF EPO, AF cTnI and AF GFAP concentrations were considered evidence of hypoxia, myocardial and brain injury, respectively. Results There were 60 cases and 60 controls. Hypoxia was present in 88% (53/60), myocardial damage in 70% (42/60) and brain injury in 45% (27/60) of fetal deaths. Hypoxic fetuses had evidence of myocardial injury, brain injury or both in 77% (41/53), 49% (26/53) and 13% (7/53) of cases, respectively. Histopathological evidence for placental dysfunction was found in 74% (43/58) of these cases. Conclusion Hypoxia, secondary to placental dysfunction, was found to be the mechanism of death in the majority of fetal deaths among structurally normal fetuses. Ninety-one percent of hypoxic fetal deaths sustained brain, myocardial or both brain and myocardial injuries in utero. Hypoxic myocardial injury was an attributable mechanism of death in 70% of the cases. Non-hypoxic cases may be caused by cardiac arrhythmia secondary to a cardiac conduction defect.

BACKGROUND: Laparoscopic primary repair is one of the main procedures used for perforated gastric ulcers, and this technique requires reproducible and secure suturing. The aim of this study was to investigate the safety and efficacy of a novel continuous suture method with barbed sutures during laparoscopic repair for perforated peptic ulcers. PATIENTS AND METHODS: Clinical data from 116 consecutive patients undergoing laparoscopic repair for perforated peptic ulcers were collected between November 2009 and October 2015. Continuous suturing with 15-cm-long unidirectional absorbable barbed sutures was used for laparoscopic repair in the study group, termed group V (n = 51). Patients who underwent laparoscopic repair with conventional interrupted sutures were defined as group C (n = 65). The complication and operative data were compared between groups. RESULTS: Although there was no difference between group V and group C in the overall complication rate (15.7% vs. 24.6%; p = 0.259), the complication rate related to suturing was lower (3.9% vs. 15.4%; p = 0.04) in group V. Group V showed rates of 0% for leakage, 2% for intra-abdominal fluid collection, and 2% for stricture; the corresponding rates in group C were 3.1, 7.7, and 4.6%, respectively. Regarding operative data, the total operation time (V vs. C, 87.7 min vs. 131.2 min), total suture time (7.1 min vs. 25.3 min), and suture time per stitch (1.2 min vs. 6.2 min) were significantly shorter in group V than in group C (p < 0.001). CONCLUSION: The use of a continuous suture technique with unidirectional barbed sutures is as safe as the conventional suture technique and allows easier and faster suturing in the repair of perforated peptic ulcers.

We report a unique case of a 67-year-old woman with neurofibromatosis type 1, who was also diagnosed with metaplastic spindle cell carcinoma of the left breast. She had many neurofibromatosis lesions on her body, as well as the mass in the left breast. After the breast mass was diagnosed as a malignant mesenchymal tumor by core needle biopsy, the patient underwent left modified radical mastectomy. Subsequently, the pathological analysis of the tumor showed it to be a metaplastic spindle cell carcinoma. The co-occurrence of neurofibromatosis type 1 and breast cancer, in particular metaplastic spindle cell carcinoma, is very rare.

Objective To determine the frequency and type of histopathologic lesions in placentas delivered by women with a normal pregnancy outcome. Methods This retrospective cohort study included placental samples from 944 women with a singleton gestation who delivered at term without obstetrical complications. Placental lesions were classified into the following four categories as defined by the Society for Pediatric Pathology and by our unit: (1) acute placental inflammation, (2) chronic placental inflammation, (3) maternal vascular malperfusion and (4) fetal vascular malperfusion. Results (1) Seventy-eight percent of the placentas had lesions consistent with inflammatory or vascular lesions; (2) acute inflammatory lesions were the most prevalent, observed in 42.3% of the placentas, but only 1.0% of the lesions were severe; (3) acute inflammatory lesions were more common in the placentas of women with labor than in those without labor; (4) chronic inflammatory lesions of the placenta were present in 29.9%; and (5) maternal and fetal vascular lesions of malperfusion were detected in 35.7% and 19.7%, respectively. Two or more lesions with maternal or fetal vascular features consistent with malperfusion (high-burden lesions) were present in 7.4% and 0.7%, respectively. Conclusion Most placentas had lesions consistent with inflammatory or vascular lesions, but severe and/or high-burden lesions were infrequent. Mild placental lesions may be interpreted either as acute changes associated with parturition or as representative of a subclinical pathological process (intra-amniotic infection or sterile intra-amniotic inflammation) that did not affect the clinical course of pregnancy.

INTRODUCTION: Dural sinus malformations, which are characterized by massively dilated dural sinuses, are one of the etiologies of an intracranial fetal cystic mass. Thrombi within these dural sinus malformations can develop while in-utero, and can be visualized by ultrasound in fetal life. Definitive postnatal diagnosis requires an autopsy. CASE REPORT: We report two thrombosed fetal dural sinus malformations which are prenatally suspected during the second trimester with ultrasonography and postnatally confirmed with autopsy. CONCLUSION: Prenatal ultrasound images and fetal autopsy findings can be useful to establish the prenatal diagnosis of thrombosed dural sinus malformation.

OBJECTIVE: We aimed to analyze the differences in prognosis and the pattern of recurrence between squamous cell carcinoma (SCC) and adenocarcinoma (ADC) in patients with cervical cancer. METHODS: We retrospectively reviewed the medical records of 969 patients with SCC and 144 patients with ADC who underwent radical hysterectomy and pelvic lymph node dissection at the Busan Paik Hospital between January 1988 and December 2010. RESULTS: Adenocarcinoma was associated with poorer disease-free survival (P = 0.0515) and overall survival (OS) (P = 0.0156) compared with SCC, and that this was more apparent for patients with International Federation of Gynecology and Obstetrics stages IIA to IIB disease. Subgroup analysis by prognostic factors for recurrence showed significant differences in the OS in the intermediate-risk subgroup (P = 0.0266), but not in the high-risk subgroup (P = 0.1674). Based on the metastatic pattern in patients with recurrence, ADC was associated with an increased risk for distant recurrence resulting from hematogenous spread compared with SCC (P < 0.0001), and patients with distant recurrence showed a worse OS (P = 0.0481) and survival after recurrence (P = 0.0016) than patients with locoregional or lymphatic recurrence. Multivariate analysis showed that ADC was a significant independent factor for poor disease-free survival (P = 0.0034) and OS (P = 0.0001). CONCLUSIONS: Adenocarcinoma is associated with a poorer prognosis and a greater probability of distanat recurrence compared with SCC. Different therapeutic strategies for ADC need to be developed, and when considering the greater tendency for distant recurrence in patients with ADC, systemic chemotherapy may have a role in reducing the risk of hematogenous spread.

OBJECTIVES: The protein V-set and Ig domain-containing 4 (VSIG4), a novel B7 family-related macrophage protein with the capacity to inhibit T-cell activation, has a potential role in cancer. Here we suggest its possibility as a therapeutic target and prognostic biomarker of ovarian cancer. METHODS: Between January 2011 and June 2015, tumor tissues and peripheral blood samples were obtained during surgery from 10 patients with benign ovarian tumors and 22 patients with ovarian cancers. Messenger RNA and protein expression levels of VSIG4 in benign tumor and cancer tissues were examined by the reverse transcription polymerase chain reaction and Western blot, respectively. Soluble VSIG4 concentrations were measured by an enzyme-linked immunosorbent assay. The correlation between VSIG4 expression and the prognosis of ovarian cancer was analyzed according to the patients' clinicopathologic characteristics. RESULTS: VSIG4 messenger RNA and protein expression levels in ovarian cancer tissues were higher than those in benign ovarian tumors (P = 0.0013 and 0.0001, respectively). Soluble VSIG4 concentrations were increased in patients with ovarian cancer compared with that in patients with benign ovarian tumors (P = 0.0452). Moreover, soluble VSIG4 levels were significantly increased in advanced-stage and recurrent ovarian cancer (P = 0.0244 and 0.0288, respectively). High VSIG4 expression of cancer tissue and low VSIG4 expression of plasma (soluble VSIG4) were associated with a longer disease-free interval (P = 0.0246 and 0.0398, respectively). CONCLUSIONS: VSIG4 is overexpressed in ovarian cancers compared with that in benign tumors. This finding supports VSIG4 being used as a potential therapeutic target for ovarian cancer. Furthermore, soluble VSIG4 levels are associated with the progression and recurrence of ovarian cancer, indicating that soluble VSIG4 may be used as a potential biomarker for predicting tumor prognosis.

Duplicated gallbladder (GB) is a rare congenital disease. Surgical management of a duplicated GB needs special care because of concurrent bile duct anomalies and the risk of injuring adjacent arteries during surgery. An 80-year-old man visited an emergency room with right upper quadrant abdominal pain. Computed tomography (CT) revealed cholecystitis with a 2-bodied GB. Because of this unusual finding, magnetic resonance choledochopancreatography was performed to detect possible biliary anomalies. The 2 GB bodies were unified at the neck with a common cystic duct, a so-called V-shaped duplicated GB. The patient's right posterior hepatic duct joined the common bile duct (CBD) near the cystic duct. The patient underwent laparoscopic cholecystectomy without adjacent organ injury, and was discharged uneventfully. Surgeons should carefully evaluate the patient preoperatively and select adequate surgical procedures in patients with suspected duplicated GB because of the risk of concurrent biliary anomalies.

Kaposiform hemangioendothelioma (KHE) is a locally aggressive vascular tumor that usually occurs in soft tissues of the extremity and rarely in the retroperitoneum. We report a unique case of isolated massive fetal ascites attributed to KHE, involving the retroperitoneum and multiple visceral organs, along with the Kasabach-Merritt phenomenon. We suspect that retroperitoneal KHE might have caused massive fetal ascites because of its high potential to invade the lymphatic vessels aggressively in the retroperitoneal space, which possibly permits intestinal lymph leakage into the peritoneal cavities.

[Purpose] The purpose of this study is to provide fundamental information for efficient management of patients after a total knee replacement (TKR) through the evaluation of changes of range of motion, pain, functional level, and quality of life. [Subjects and Methods] For a total of 63 knee osteoarthritis patients, VAS, KSKS, KSFS, HSS, WOMAC scores and quality of life were evaluated for functional levels at pre-operation, post-operation, six months after operation, and 12 months after operation. [Results] After the TKR operations, participants showed significant improvement in KSKS, KSFS, WOMAC, and SF-36 scores when compared to pre-operation. [Conclusion] After a TKR operation, ROM, and pain management, along with a therapeutic program for improvement of function, should be conducted 6 months after the operation.
