Acute diffuse peritonitis secondary to a seminal vesicle abscess: A case report.

BACKGROUND: Seminal vesicle abscess (SVA) is the manifestation of a relatively rare urinary system infection. In response to urinary system inflammation, an abscess forms in special locations. However, acute diffuse peritonitis (ADP) induced by SVA is unusual. CASE SUMMARY: We report a case of a left SVA in a male patient complicated with pelvic abscess, ADP, multiple organ dysfunction syndrome, infectious shock, bacteremia, and acute appendiceal extraserous suppurative inflammation as a result of a long-term indwelling urinary catheter. The patient received a course of morinidazole + cefminol antibiotics but showed no obvious relief, so the perineal SVA underwent puncture drainage and abdominal abscess drainage + appendectomy was performed. The operations were successful. After the operation, anti-infection, anti-shock, and nutritional support treatments were continued and various laboratory indicators were regularly reviewed. The patient was discharged from the hospital after recovery. This disease is a challenge for the clinician because of the unusual spreading path of the abscess. Moreover, appropriate intervention and adequate drainage of abdominal and pelvic lesions are necessary, especially when the primary focus cannot be determined. CONCLUSION: The etiology of ADP varies, but acute peritonitis secondary to SVA is very rare. In this patient, the left SVA not only affected the adjacent prostate and bladder but also spread retrogradely through the vas deferens, forming a pelvic abscess in the loose tissues of the extraperitoneal fascia layer. Inflammation involving the peritoneal layer led to ascites and pus accumulation in the abdominal cavity, and appendix involvement led to extraserous suppurative inflammation. In clinical practice, surgeons need to consider the results of various laboratory tests and imaging examinations to make comprehensive judgments involving the diagnosis and treatment plan.

Synchronous hepatocellular carcinoma and gallbladder adenocarcinoma with neuroendocrine differentiation: a case report and literature review.

BACKGROUND: Double primary cancers have a low incidence rate, and synchronous hepatocellular carcinoma and gallbladder adenocarcinoma are rarely reported. Here, we report such a case- the 12th case of synchronous double primary cancers featuring HCC and GC, but the first case of neuroendocrine differentiation in the gallbladder. CASE PRESENTATION: A 77-year-old female was admitted to the hospital complaining of weakness and inappetence for six months. Contrast-enhanced computed tomography (CT) of the abdomen indicated an 11 cm space-occupying lesion in the right lobe of the liver. Later, magnetic resonance imaging showed a high possibility of a massive hepatoma, and multiple gallstones were also seen. After transhepatic arterial chemoembolization, a repeat abdominal CT showed obvious local nodular thickening in the gallbladder wall. Finally, resection of the right lobe of the liver and cholecystectomy were performed. During an approximately 2-year follow-up, the patient recovered uneventfully without recurrence or metastasis. CONCLUSION: The disease in this case is rare and lacked typical radiological features. More precise and advanced diagnostic techniques are needed to obtain a clear diagnosis and refine treatment strategies. The management strategy should always be curative, even in the presence of multiple malignancies.

Up-regulation of LINC00161 correlates with tumor migration and invasion and poor prognosis of patients with hepatocellular carcinoma.

Accumulating evidence suggested that long non-coding RNAs (lncRNAs) play essential roles in various biological processes, including tumorigenesis. Aberrant expression of LINC00161 has been reported in some cancer types, however, the association of LINC00161 and hepatocellular carcinoma (HCC) has not been evaluated. Here, we measured the expression of LINC00161 in HCC tissues and corresponding normal liver tissues using real-time PCR. The result showed that the expression level of LINC00161 was significantly higher in HCC tissues. Further analysis indicated that HCC patients with higher LINC00161 expression have shorter survival. Multivariate Cox regression analysis showed that LINC00161 expression was an independent prognostic factor for the overall survival. Furthermore, our result indicated that knock-down of LINC00161 can significantly inhibit liver cancer cell migration and invasion. The present work indicated that LINC00161 might serve as an oncogenic gene and play a pivotal role in promoting tumor migration and invasion in HCC. Our work implicates the promising effect of LINC00161 on the prognosis of HCC.

[Re-optimized technology of protective ileostomy with no need of reversal].

OBJECTIVE: To explore the clinical application of aoptimizedtechniquebased onpreviouslyreported protecting stoma with no need forreversal. METHODS: Thetechniquealso used "the assembly of drainage device" to performprotecting ileostomy. The original method includes enterotomy at the terminal ileum to placedrainage device, which was optimized as follows: two intestinal pursestring with 0.5 cm distance were placed 5 cm away from the ileocecal valve. Transverse enterotomy was performed in the anti-mesenteric side. The assembly was placed at the root of the appendix between two pursestring, and then the intestine purse suture was tighten. Ligation of the small intestine anastomosis between the anastomosis ring at both ends was carried out, and theanastomosis ring was deployed. From the root of the appendix in the cecum wall, the assembly was embedded about 2 cm and pulled out of abdominal cavitythough the Trocar hole. RESULTS: Seventeen cases of ultra-low rectal cancer completed protecting stoma, including 11 cases through ileocecal protective stoma. All the anastomosis healed well. Defecation drainage tube was removed 3-5 weeks after anastomosis ring degradation. Drainage nozzle healed after 3 to 5 days, and no complications occurred. CONCLUSION: The optimized ileocecal protective ileostomy has the following advantages: (1)wound healing time is significantly shorter. (2)secondary intestinal fistula can be prevented. (3)no need to fix ileum and less chance of subsequent volvulus, intestinal obstruction.

[Clinical degree of the superior mesenteric vein involvement with the surgery in the pancreas uncinate process carcinoma].

OBJECTIVE: To create the clinical degree of the superior mesenteric vein (SMV) involvement in pancreas uncinate process carcinoma (PUPC) and its clinical significance to be discussed. METHODS: According to the contiguous relationship between the SMV and the PUPC, the clinical degree of SMV involvement in PUPC are as followings four grades, 1 grade, the grade of clear boundary. 2 grade, the grade of fuzzy boundary. 3 grade, the grade of dissolved boundary. 4 grade, the grade of SMV infringed. The coherence between the type under the CT scan (Tx) and the type under the inoperative judgement (Sx) were analyzed with Kappa-test. RESULTS: There is a significant difference between the grade of SMV involvement and the surgery. The resection rate is 100% in 1st grade, 97.4% in 2nd grade, 65.8% in 3rd grade and 21.7% in 4th grade. There is coherent in the degree judgement between the CT scan and the inoperative inspection (U = 15.96, P < 0.01). CONCLUSIONS: There is clinical significance to establish the degree of SMV involvement in PUPC. It is helpful for clinician to accurately know its anatomic characteristic and decide more reasonable surgical strategy.
