BACKGROUND/AIMS Peritoneal trauma activates a cascade of peritoneal defence mechanisms responsible for postoperative intra-abdominal tumour recurrence. After peritoneal trauma, inflammatory cells and soluble factors are present in the abdominal cavity and can be captured in lavage fluids. The present study evaluated which component enhances intra-abdominal tumour recurrence. Furthermore, we eva...

BACKGROUND Gastric cancer with cancer cells on peritoneal cytology has very poor prognosis because of the existence of simultaneous peritoneal metastasis. Here we performed a dose-escalation study of intraperitoneal docetaxel (DTX) combined with S-1 to determine the maximum-tolerated dose (MTD) and recommended dose (RD) in gastric cancer with peritoneal dissemination. PATIENTS AND METHODS Twe...

PURPOSE Bacterial translocation (BT) is common in colon cancer patients and may be associated with increased occurrence of septic complications as well as with adverse oncologic outcomes. The aim of the present study was to correlate the BT detectable through peritoneal lavage culture or identified by abnormal inflammatory parameters with the clinicopathologic parameters and the short-term prog...

Passive intraperitoneal transfer of sera from Fasciola hepatica-infected sheep, cattle or rats can protect naive rats from F. hepatica infection, suggesting a parasite killing mechanism within the peritoneal cavity that is dependent on the presence of parasite-specific antibody. We investigated antibody-dependent cell-mediated cytotoxicity by resident peritoneal lavage cell populations, contain...

To this day, the treatment of generalized peritonitis secondary to diverticular perforation is still controversial. Recently, in patients with acute sigmoid diverticulitis, laparoscopic lavage and drainage has gained a wide interest as an alternative to resection. Based on this backdrop, we decided to perform a systematic review of the literature to evaluate the safety, feasibility, and efficac...

Excessive consumption of ethanol (EtOH) suppresses innate immunity, but the mechanisms have not been fully delineated. The present study was conducted to determine whether EtOH suppresses TLR signaling in vivo in mice and to characterize the downstream effects of such suppression. Degradation of IL-1R-associated kinase 1 induced by a TLR3 ligand in peritoneal cells ( approximately 90% macrophag...

Purified rat peritoneal mast cells have a 10-20-fold higher dipeptidyl peptidase II (DPP II) activity as compared with that of macrophages from the same source. Upon stimulation with the secretagogue Compound 48/80, DPP II is released from peritoneal-lavage cells and from purified mast cells, but not from purified macrophages, in a dose-dependent manner. Maximally, about one-third of the DPP II...

PURPOSE We encountered a case where an infection with group A streptococcus (GAS; ie, Streptococcus pyogenes) initially caused primary peritonitis and then subsequently caused streptococcal toxic shock syndrome. The patient's life was likely saved by an emergency laparotomy followed by extensive peritoneal lavage and drainage. CASE PRESENTATION A 40-year-old woman was admitted to the Emergenc...
