AIM: To determine if cholecystectomy and liver's round ligament removal is a necessary step during cytoreductive surgery (CRS) and HIPEC METHODS: This was a retrospective observational study based on records from 180 patients treated in our center from 2005 to 2014. All patients have been offered CRS and HIPEC for peritoneal pseudomixoma (20 patients), peritoneal mesothelioma (7 patients), peritoneal carcinomatosis from ovarian cancer (66 patients), colorectal cancer (42 patients), gastric cancer (10 patients), mucinous adenocarcinoma of the appendix (28), and other abdominal malignancies (7 patients)...

The authors present the case of a 56 year-old patient diagnosed with pseudomyxoma peritonei, 4 years after being subjected to a left adnexectomy for ovarian cystadenoma. The intra-parietal insemination of the mucinous cells enabled the development,at this level, of a gelatinous mass that raised problems of differential diagnosis with irreducible incisional hernia. In what regards the preoperative signs of clinical and paraclinical diagnosis we consider them obscure and nonspecific. The abdominal computed tomography revealed the presence of a massive intraperitoneal collection, but given the rarity of this pathology the initial diagnosis was made in the course of the exploratory laparotomy...

AIM: Intrathoracic extension in patients with pseudomixoma peritonei is a rare event, but spread of the tumour beyond the abdomen in to pleuropulmonary cavity has been reported. MATERIALS AND METHODS: We report a case of a 50-years-old woman with synchronous pleural manifestation of pseudomixoma peritonei by a mucinous ovarian cancer. During the abdominal cytoreductive surgery an extensive disease under the right hemidiaphragm was noted, requiring partial diaphragmatic resection...

Traditionally, peritoneal carcinomatosis (PC) was regarded as an untreatable condition; however, the introduction of locoregional therapies combining cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) approximately two decades ago has changed this view. There is controversy, however, when a PC arises from pancreatic cancer. We have reported on an extraordinary case of an aggressive pseudomixoma peritonei arising from an invasive intraductal papillary mucinous neoplasm (IPMN) treated with complete cytoreduction and HIPEC...

BACKGROUND: In order to treat the peritoneal carcinomatosis from abdominal neoplasms has been recently proposed complete peritonectomy associated with IntraPeritoneal Hyperthermic Chemotherapy (IHPC). AIM OF THE STUDY: Estimate of postoperative morbidity and mortality and short-term outcome. METHODS: Twenty-four patients with peritoneal carcinomatosis or positive cytology at peritoneal washing were treated in our Department from January 2005 to October 2007...

The adenocarcinoma of the urachus is very rare tumor, with an incidence of 1/5.000.000 inhabitants, represents less than 0.001 of all types of bladder cancer. Peritoneal pseudomixoma is a rare neoplasm characterized by mucinous acites that involvement the peritoneal surface and omentum. Usually is associated with benign o malignant mucinous tumor of the appendix or ovary. In this paper, we present a case of peritoneal pseudomixoma caused by a mucinous adenocarcinoma of the urachus.

Appendiceal mucocele is a term used to describe the dilatation of the vermiform appendix produced by an intraluminal accumulation of mucus. Four pathological processes have been described that may lead to an appendiceal mucocele: obturation of cecoappendiceal communication, mucosal hyperplasia, mucinous cystadenoma and mucinous cystoadenocarcinoma. The most frequent is mucinous cystadenoma, seen in 50% of appendiceal mucoceles. 6% of patients with appendiceal mucocele develop peritoneal pseudomixoma, possibly through dissemination of the epithelial cells into the abdominal cavity...

Pseudomixoma peritonei (PMP) is a rare neoplasia with a low grade of clinical malignity. Generally, the main treatment of this tumor is the surgical debulking. Best results are obtained combining surgery and hyperthermic antiblastic peritoneal perfusion (HAPP) with CDDP and MMC. From April '97 to March 2003, we operated on 132 patients, 8 times with a palliative intent. In 27 times we achieved a complete cytoreduction (17 CC0 and 10 CC1) followed by HAPP. As regards results, no post-operative mortality was reported and 19% of major morbidity was observed...

Pseudomixoma Peritonei (PMP) is an uncommon neoplasm characterised by mucinous ascites and multifocal amorphous mucous substances involving the peritoneal surface, omentum and bowel loops. Although the origin of the Pseudomixoma Peritonei is still unclear, it could be due to the perforation of an ovarian mucinous cystoadenoma or an appendiceal mucocele. The further pelvic dissemination of the endotumor material, which adhere itself into the peritoneal surface, may induce an intra-abdominal transformation of the peritoneal mesothelium into mucin-producing tissue...

Pseudomixoma peritonei is a rare neoplasm characterized by mucinous ascites and the mucinous involvement of peritoneal surfaces, omentum and bowel loops. Usually pseudomixoma peritonei is associated with benign or malignant mucinous tumor of the appendix or ovary. The diagnosis of pseudomixoma peritonei is difficult because laboratory and radiology results are frequently nondiagnostic. We report a case that was initially mistaken for carcinomatosis of unknown origin and that underwent cytoreductive procedure and omentectomy as the treatment of choice...
