BACKGROUND
Extrahepatic, abdominal surgery in patients with cirrhosis is associated with high morbidity and mortality. This systematic review presents the current evidence available on the utility of a preoperative transjugular intrahepatic portosystemic shunt (TIPS), assessed by its effect on surgical candidacy and postoperative mortality and morbidity in patients with cirrhosis undergoing extrahepatic, abdominal surgery.
METHODS
MEDLINE, EMBASE, Cochrane Library and Web of Science databases were searched till 2022 to identify studies. Studies that reported characteristics and outcomes of participants with cirrhosis that had a TIPS inserted in preparation for extrahepatic, abdominal surgery, were included.
RESULTS
Twenty-one studies (292 patients) were included, of which three were comparative studies and the remaining case series or case reports. A TIPS was inserted in 190 patients prior to surgery. At least one clinical sign of portal hypertension identified by ascites, varices, and/or hepatic encephalopathy were present in all patients except one patient. Fifty eight percent had decompensated cirrhosis. TIPS insertion was successful in all patients. Eighty-nine percent of patients underwent surgery. The cumulative 30-day postoperative mortality was 2% (3/148). There were 97 complications reported in 168 patients (57%). In the three comparative studies, there was no difference in mortality or morbidity among patients who underwent TIPS prior to surgery compared to those who did not undergo TIPS prior to surgery.
CONCLUSION
Preoperative TIPS has been used to improve surgical candidacy in patients with cirrhosis undergoing extrahepatic, abdominal surgery, while reducing complications of portal hypertension. However, there is not enough evidence to support that TIPS insertion prior to extrahepatic, abdominal surgery significantly improves surgical outcomes in patients with cirrhosis and further studies are needed.

BACKGROUND
Peritoneal carcinomatosis was the main reason leading to gastric cancer (GC)-related death. We aimed to explore the roles of dysregulated microRNAs (miRNAs) and related immune regulation activities in GC-associated malignant ascites.
METHODS
GSE126399 were downloaded from GEO database. Differentially expressed miRNAs in GC ascites samples was firstly screened, and critical miRNAs were further investigated by LASSO (least absolute shrinkage and selection operator) logistic regression and random forest (RF) algorithm. Receiver operating characteristic of critical miRNAs was also constructed. Moreover, functional analysis, immune cell infiltration associated with differentially expressed mRNAs were further analyzed. After selecting key modules by weighted gene co-expression network analysis, mRNAs related with survival performance and transcription factor (TF)-miRNA-mRNA network were constructed.
RESULTS
Hsa-miR-181b-5p was confirmed as critical differentially expressed miRNAs in GC ascites. Then, the tumor samples were divided into high- and low- expression groups divided by mean expression levels of hsa-miR-181b-5p, and subjects with high hsa-miR-181b-5p levels had better survival outcomes. In total, 197 differentially expressed mRNAs associated with hsa-miR-181b-5p levels were obtained, and these mRNAs were mainly enriched in muscle activity and vascular smooth muscle contraction. Hsa-miR-181b-5 was positively related with activated CD4 T cells and negatively related with eosinophil. 17 mRNAs were selected as mRNAs significantly related with prognosis of GC, such as PDK4 and RAMP1. Finally, 75 TF-miRNA-mRNA relationships were obtained, including 15 TFs, hsa-miR-181b-5p, and five mRNAs.
CONCLUSION
Our data suggest that the differentially expressed hsa-miR-181b-5p in ascites samples of GC patients may be a valuable prognostic marker and a potential target for therapeutic intervention, which should be validated in the near future.

BACKGROUND
Liver transplantation is an increasingly frequent surgical procedure, with elevated rates of postoperative incisional hernias ranging from 5% to 46%. There are numerous known risk factors for incisional hernia, including the type of incision, patient sex, and presence of comorbidities such as diabetes, ascites, older age, and the use of steroids. Most studies on the treatment of incisional hernias in patients who have undergone liver transplantation have shown consistently high rates of complications. Consequently, we propose the use of nonvascular fascia for the symptomatic treatment of incisional hernias in patients with concomitant liver transplantation.
METHODS
We performed our new technique on 8 patients, who had previously undergone liver transplantation, between January 2019 and January 2023. The patients were examined using imaging techniques during the follow-up period.
RESULTS
Of the 8 patients, 7 were liver transplant recipients and 1 was a combined liver-kidney transplant patient. The median donor age was 57 y (5-66 y), whereas the mean recipient age was 58 y (31-66 y). The median patient height and weight were 163 cm (117-185 cm) and 76 kg (17-104 kg), respectively. Immunosuppression did not change in fascia recipients. The median time between transplantation and hernia repair surgery was 41 mo (5-116 mo). The sizes of the aponeurotic defects varied from 6 × 6 to 25 × 20 cm. Two patients experienced complications: one experienced bulging that required reintervention and the other experienced surgical site seroma. There was no mortality related to the use of the technique, and none were reported during follow-up.
CONCLUSIONS
With its promising results, nonvascularized fascial transplantation can be a successful treatment for incisional hernias in patients who had previously received a liver transplant.

Retroperitoneal cysts, a rare surgical phenomenon, present diagnostic challenges due to their typically asymptomatic nature. A 62-year-old male presented with a 4-month history of abdominal distension and increased burping. Upon clinical examination, a soft, distended, nontender abdomen with a palpable mass extending from the epigastric region to 3 cm below the umbilicus was revealed. Imaging revealed a 14.6 cm × 15.8 cm × 16.4 cm nonenhancing retroperitoneal lesion, compressing the right ureter and causing mild right hydronephrosis. Multiple gall bladder calculi, an umbilical hernia, and lipomatous lesions associated with adrenal glands were also discovered. Laparoscopic retroperitoneal cystectomy, cholecystectomy, and umbilical hernia repair were performed. Intraoperatively, 150 ml ascitic fluid and 1200 ml cystic fluid were found. This case highlights the intricate clinical presentation of a retroperitoneal cyst, emphasizing the need for surgical exploration. Successful laparoscopic management contributes to the evolving understanding of optimal treatment strategies.

Patients presenting with ascites should be properly evaluated to differentiate potential etiologies. Then, based on the evaluation, we can tailor more accurate treatment plans for patients. Cirrhosis is the most common cause, and others include cancer, heart failure, and, in our case, rarely a visceral artery rupture. Rupture of the splenic artery aneurysm can be lethal and should be considered as a possible differential in a patient with no previous history of heart failure, cancer, or cirrhosis. Our patient was identified after an initial misdiagnosis of possible ascites secondary to cirrhosis. However, input from an interventional radiologist led to proper identification and tailored management. Early treatment is crucial to prevent complications, including death.

Small-cell carcinoma of the ovary, the hypercalcemic type (SCCOHT) is a rare, aggressive tumor that primarily affects young females. It is a monogenic disorder caused by germline and/or somatic mutations. Here, we report a case of SCCOHT harboring multiple previously unreported somatic mutations in (c.2866_2867delC>T; c.3543del). A 28-year-old breastfeeding Japanese female presented to a previous hospital with nausea and vomiting. She had no family history of relevant malignancies, including ovarian cancer. Based on an evaluation performed at another institution, she was referred to a gynecologist for suspected ovarian cancer. Imaging studies revealed a 16×15 cm heterogenous enhancing mass within the right ovary without lymph node or distant metastasis. She had mild ascites without peritoneal dissemination, but there was an elevation in the serum calcium level (15.1 mg/dL). The patient underwent cytoreductive surgery and was pathologically diagnosed with SCCOHT. Auxiliary immunohistochemical staining confirmed the loss of SMARCA4 protein expression. The patient was diagnosed with the International Federation of Gynecology and Obstetrics (FIGO) 2014 stage IA (pT1a pN0 M0). The serum calcium levels returned to normal post-surgery. Matched-pair analysis using tumor tissue and peripheral blood revealed multiple somatic mutations in , but no deleterious germline mutations were present. Microsatellite instability was not significant, and the patients had a heterozygous mutation of . She underwent six cycles of irinotecan hydrochloride plus cisplatin chemotherapy and achieved complete remission. The patient was finally examined and evaluated 45 months postoperatively; there was no evidence of the disease. Overall, the genetic findings will not aid in the SCCOHT diagnosis and relevant genetic counseling; however, they may have implications for the treatment of this disease in the future.

Peritonitis, an inflammation of the peritoneal cavity, can be caused by various factors. The presence of ascites in a cancer patient is concerning for either metastasis or advanced cancer. Diagnosing acute peritonitis in a patient with cancer-related ascites can be quite challenging and often requires additional diagnostic procedures, such as paracentesis, to confirm the diagnosis and identify the exact cause of the ascites. Even with paracentesis, determining the exact cause of ascites can be a diagnostic challenge. Peritoneal carcinomatosis, with a poor survival rate, can originate from the peritoneal lining itself or result from intra-abdominal cancer, and trying to determine its origin can be difficult. We present the case of a 68-year-old female patient with a known history of cancer experiencing worsening ascites and peritonitis.

BACKGROUND
Phytobacter diazotrophicus (P. diazotrophicus) is an opportunistic pathogen that causes nosocomial outbreaks and sepsis. However, there are no reports of P. diazotrophicus isolated from human blood in China.
CASE PRESENTATION
A 27-day-old female infant was admitted to our hospital with fever and high bilirubin levels. The clinical features included jaundice, abnormal coagulation, cholestasis, fever, convulsions, weak muscle tension, sucking weakness, ascites, abnormal tyrosine metabolism, cerebral oedema, abnormal liver function, clavicle fracture, and haemolytic anaemia. The strain isolated from the patient's blood was identified as P. diazotrophicus by whole-genome sequencing (WGS). Galactosemia type 1 (GALAC1) was diagnosed using whole-exome sequencing (WES). Based on drug sensitivity results, 10 days of anti-infective treatment with meropenem combined with lactose-free milk powder improved symptoms.
CONCLUSION
P. diazotrophicus was successfully identified in a patient with neonatal sepsis combined with galactosemia. Galactosemia may be an important factor in neonatal sepsis. This case further expands our understanding of the clinical characteristics of GALAC1.

Ovarian cancer often develops resistance to conventional therapies, hampering their effectiveness. Here, using ex vivo paired ovarian cancer ascites obtained before and after chemotherapy and in vitro therapy-induced secretomes, we show that molecules secreted by ovarian cancer cells upon therapy promote cisplatin resistance and enhance DNA damage repair in recipient cancer cells. Even a short-term incubation of chemonaive ovarian cancer cells with therapy-induced secretomes induces changes resembling those that are observed in chemoresistant patient-derived tumor cells after long-term therapy. Using integrative omics techniques, we find that both ex vivo and in vitro therapy-induced secretomes are enriched with spliceosomal components, which relocalize from the nucleus to the cytoplasm and subsequently into the extracellular vesicles upon treatment. We demonstrate that these molecules substantially contribute to the phenotypic effects of therapy-induced secretomes. Thus, SNU13 and SYNCRIP spliceosomal proteins promote therapy resistance, while the exogenous U12 and U6atac snRNAs stimulate tumor growth. These findings demonstrate the significance of spliceosomal network perturbation during therapy and further highlight that extracellular signaling might be a key factor contributing to the emergence of ovarian cancer therapy resistance.

Anisakiasis is a parasitic infection affecting the human gastrointestinal tract. It is caused by the consumption of contaminated, raw or inadequately cooked fish or squid, which is typically used for making sushi and sashimi. Most cases involve gastric anisakiasis, whereas intestinal anisakiasis is rare. This report describes the case of a 63-year-old Japanese woman with a history of raw fish consumption who presented with acute-onset abdominal pain and vomiting. Abdominal computed tomography (CT) demonstrated thickened small bowel loops and ascites on the liver surface. The patient was admitted for supportive care. On the second day of hospitalization, contrast-enhanced abdominal CT revealed that the ascites had moved from the liver surface to the pouch of Douglas. On the fifth day of hospitalization, the patient was discharged with a substantial improvement in abdominal pain. Five days after the discharge, her eosinophil count was elevated, and parasitic disease was therefore suspected. Anti-Anisakis IgG/A and IgE (RAST) antibody levels were elevated, confirming the diagnosis of intestinal anisakiasis. A review of 51 reported cases of intestinal anisakiasis suggests that the presence of ascites and measurement of anti-Anisakis antibody titers are helpful for diagnosis in cases presenting with nonspecific abdominal symptoms after consumption of raw or undercooked fish.
