Surgery for rectal cancer patients with an ileal conduit after total cystectomy is difficult because adhesions in the pelvis and around the ileal conduit are expected. In the present case, we performed robot-assisted low anterior resection of the rectum in a 69-year-old male patient with rectal cancer who underwent ileal conduit diversion after total cystectomy. In this procedure, the port was inserted into the left upper abdomen as a first step, and two additional ports were added on the left side.

Double inferior vena cava (DIVC) is a rare but generally asymptomatic condition that is often detected incidentally by radiological examinations such as computed tomography (CT). Here, we describe the case of a 73-year-old woman with DIVC, who underwent robot-assisted surgery (RS) for rectal cancer. In this case, 3D CT angiography showed DIVC with an interiliac vein from the left common iliac vein and a tortuous aorta.

Objective: The use of laparoscopic surgery for rectal disease is expected to provide good cosmetic benefits for patients postoperatively. However, this expectation is significantly reduced when a diverting ileostomy is created. We present a new technique that reduces the size of the skin wound by constructing a diverting ileostomy in the umbilicus.

Background: In the ABSOLUTE trial, weekly nanoparticle albumin-bound paclitaxel (w-nab-PTX) showed non-inferiority to weekly solvent-based paclitaxel (w-sb-PTX) for overall survival (OS). Thus, w-nab-PTX might be an option for second-line chemotherapy in advanced gastric cancer (AGC). However, predictive factors for efficacies of these agents have not been evaluated.

The principle of empirical therapy for patients with intra-abdominal infections (IAI) should include antibiotics with activity against Enterobacteriaceae and Bacteroides fragilis group species. Coverage of Pseudomonas aeruginosa, Enterobacter cloacae, and Enterococcus faecalis is also recommended for hospital-associated IAI. A nationwide survey was conducted to investigate the antimicrobial susceptibility of pathogens isolated from postoperative IAI.

Article Synopsis
  • A 39-year-old woman with malignant foot melanoma underwent surgery that included wide excision of the tumor and a sentinel lymph node biopsy, which tested positive for cancer.
  • A CT scan showed swelling in her right iliac lymph nodes, and a PET-CT confirmed abnormal activity, leading to a laparoscopic pelvic lymph node dissection.
  • During the surgery, several black lymph nodes indicating metastasized melanoma were found; despite this approach being non-standard, its minimally invasive nature suggests potential for broader application in treating different cancers.

Tumor metastasis depends on cell adhesiveness, motility and deformability, resulting from quantitative alterations and rearrangement of various actin-binding cytoskeletal components, such as cortactin and fascin. To clarify the involvement of cortactin and fascin expression in tumorigenesis and progression of gastric carcinoma, we performed immunohistochemistry (IHC) on tissue microarray containing gastric carcinomas, adenomas and adjacent non-neoplastic mucosa (ANNM) using the antibodies against cortactin (Ab-466, -421) and fascin as well as a comparison of their expression with clinicopathological parameters of the tumors. Gastric carcinoma cell lines MKN28, AGS, MKN45, KATO-III and HGC-27 were studied for both proteins by IHC.

Glucose-related proteins (GRPs) are ubiquitously expressed in endoplasmic reticulum and able to assist in protein folding and assembly; consequently, they are considered as molecular chaperones. GRP78 and GRP94 expression was induced by glucose starvation and up-regulated in the malignancies. To clarify the roles of both molecules in tumorigenesis and progression of gastric carcinomas, immunohistochemistry was used on tissue microarray containing gastric carcinomas, adenomas, and nonneoplastic mucosa using the antibodies against GRP78 and GRP94, with a comparison of their expression with clinicopathological parameters of carcinomas.
