Mesenteric cyst: report of a case-resulting in pseudomyxoma peritonei.

Background: A mesenteric cyst may have an embryonic, traumatic, neoplastic or infectious origin. In rare cases mesenteric cysts may contain neoplastic epithelium. A mesenteric cyst has not previously been recorded as the cause of pseudomyxoma peritonei.

Gastric perforation following cytoreductive surgery with perioperative intraperitoneal chemotherapy.

Objective: Gastrointestinal tract perforation after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has an incidence of 6%. The most common site is the small bowel. The trauma of CRS and delay in wound healing due to HIPEC has been thought to cause this complication.

Tailgut cyst, an unusual cause of pseudomyxoma peritonei.

Background: Retrorectal hamartoma, also known as tailgut cyst, is a rare tumor that arises from remnants of the embryonic postanal gut. The tumor occurs in the retrorectal space and may undergo malignant degeneration.

Methods: The clinical information on a single patient with pseudomyxoma peritonei associated with a tailgut cyst was reviewed and a literature review of the subject performed.

Interstitial pneumonitis following intrapleural chemotherapy.

Background: Mucinous neoplasms within the abdomen may disseminate by direct extension through the diaphragm to involve the pleural space. Treatment of this condition is by parietal and visceral pleurectomy followed by hyperthermic intrapleural chemotherapy.

Case Presentation: In this case report a patient developed persistent right upper lobe interstitial pneumonitis and progressive parenchymal fibrosis following intrapleural chemotherapy treatment with mitomycin C and doxrubicin.

Thin-walled cysts as a pathognomonic CT finding in cystic mesothelioma.

Aim: Cystic mesothelioma is a rare disease that results in abdominal distention and poorly defined abdominal pain. Diagnosis has always been made by tissue biopsy rather than by radiologic studies.

Materials And Methods: Our experience with 7 patients with cystic mesothelioma includes 4 patients who had not had prior surgery before the performance of a high resolution CT scan.

Compartment syndrome of the leg associated with lithotomy position for cytoreductive surgery.

Background: Compartment syndrome is seen in patients who have ischemic damage to muscle that is contained within a fascial compartment. A pathologic cycle is initiated when tissue injury produces swelling and compromises muscle perfusion. Patients undergoing cytoreductive surgery combined with intraperitoneal chemotherapy are required to be in the lithotomy position for many hours.

Perioperative outcomes of cytoreductive surgery and perioperative intraperitoneal chemotherapy for non-appendiceal peritoneal carcinomatosis from a prospective database.

Background: Cytoreductive surgery combined with perioperative intraperitoneal chemotherapy has expanded its application in the management of peritoneal carcinomatosis from gastrointestinal and ovarian malignancies. An accurate assessment of perioperative outcomes is crucial for integration of this combined procedure into clinical practice.

Methods: A prospective study of 80 patients undergoing the combined treatment for non-appendiceal peritoneal carcinomatosis was conducted.

Splenic metastases from mucinous neoplasms of the appendix and colon.

Aims And Background: Splenic metastases associated with mucinous intraabdominal tumors have been an enigma in the radiologic and oncology literature. These focal parenchymal defects from a non-metastasizing malignancy within an organ that rarely develops metastatic foci, even with high-grade cancer, were studied.

Methods: Information on 9 patients who underwent splenectomy with intraparenchymal splenic masses associated with appendiceal or colorectal mucinous tumors with peritoneal dissemination was collected.
