Pseudomixoma peritonei associated with appendiceal cistoadenoma rupture: case report.

Appendiceal mucocele represents specimen finding in 0.2-0.3% out of appendectomies. The rupture or perforation in peritoneal cavity might cause pseudomixoma peritonei (PMP), with multiple mucinous deposits in the abdominal cavity. We report a case of PMP caused by a perforated appendiceal cistoadeonoma.

Mirizzi syndrome: a challenging diagnosis. Case report.

Mirizzi Syndrome (MS) is an uncommon complication of chronic gallstone disease defined as a common bile duct (CBD) obstruction secondary to gallstone impaction in the cystic duct or gallbladder neck. MS is still a challenging clinical situation: preoperative diagnosis of MS is complex and can be made in 18-62.5% of patients. Over 50% of patients with MS is diagnosed during surgery. In most of cases, laparotomy is the preferred surgical approach. We report the case of a 70-year-old woman with a history of asthenia, jaundice, abdominal pain and preoperative imaging that suggest the presence of biliary stones with a choledocal stenosis. Intraoperatively, a MS with cholecysto-biliary fistula involving less than two-thirds of the circumference of the bile duct was diagnosed and successfully treated.

Jejunal metastasis of Merkel cell carcinoma: case report.

Merkel cell carcinoma (MCC) of the skin is a rare but aggressive cutaneous neuroendocrine-derived malignancy that predominantly affects elderly white males. The presence of distant nodal metastases significantly impacts survival. Typical metastatic sites of MCC are liver, bone, brain and skin. Gastrointestinal metastases are uncommon and small bowel is the most common site followed by stomach. We report a case of symptomatic MCC jejunal metastasis.

[Intestinal perforation due to accidental ingestion of foreign bodies]. / Perforazione intestinale da ingestione accidentale di corpo estraneo.

Usually the ingested foreign bodies (IFB) pass the gastrointestinal tract making no lesions. Sometimes IFB could lead to a gastrointestinal perforation. The most frequently perforating IFB are chicken or fish bones and toothpicks, while risks factors are mental retardation, alcohol or drug abuse, denture usage, quick eating or habitual chewing of toothpicks. The accidentally ingestion in a high risk patient with unclear symptoms, added to a low sensitive diagnostic imaging, lead to intraoperative diagnosis in one half cases of gastrointestinal perforation by IFB. Furthermore the surgical treatment range between the less minimal invasive laparoscopic IFB extraction and intraabdominal hole suture to a laparotomic bowel or colic resection. Herein we describe our experience in 3 cases of gastrointestinal perforation by IFB have been diagnosed at surgery and treated by IFB extraction and hole suture (in 2 patients; 1 laparoscopy, 1 laparotomy) or open right emicolectomy (1 patient).

Laparoscopic and open gastric resections for malignant lesions: a prospective comparative study.

BACKGROUND: Whereas laparoscopy for benign diseases provides clear advantages over traditional surgery, the benefits of laparoscopic gastric resection for malignant diseases are less clear. The objectives of this study were to compare prospectively the clinical outcomes between completely laparoscopic and open total and partial gastrectomies for malignant diseases and to assess whether laparoscopic gastrectomies obtain adequate margins and follow oncologic principles. METHODS: Between April 1995 and March 2004, a prospective comparative study was performed comparing eight patients who underwent laparoscopic total gastrectomy with 11 patients who underwent open total gastrectomy, and 16 patients who underwent laparoscopic partial gastrectomy with 17 who patients underwent open partial gastrectomy. Stage, extent of lymphadenectomy, and long-term follow-up were examined. The intraoperative and postoperative details of the two groups were compared. RESULTS: The laparoscopic group patients had fewer intraoperative complications while the operative time was similar to that of the open group. Both ambulation and hospital stay were significantly shorter in the laparoscopic groups than in the open groups. The short-term morbidity was lower in the laparoscopic groups and there were no cases of death, whereas one case of postoperative death occurred after an open total gastrectomy. There was no need to convert to open surgery. The number of lymph nodes obtained in the laparoscopic and open procedures was not significantly different. In addition, all resected margins were tumor free in the laparoscopic group, whereas tumor involvement was presented in the margin of one specimen in the open group. CONCLUSIONS: The totally laparoscopic approach to total and partial gastrectomies had good results and was proven to be a feasible and safe procedure. In addition, the laparoscopic procedures are superior to open surgeries in terms of faster postoperative recovery, shorter hospital stay, and better cosmetic outcomes. A totally laparoscopic approach for early and advanced gastric cancer can obtain adequate margins and follow oncologic principles.

Soluble CD30 serum antigen in Kawasaki disease.

Very high levels of sCD30, a glycoprotein surface antigen expressed by T lymphocytes and other mononuclear cells of the immune system, were found in serum samples from 10 children with typical Kawasaki disease (KD), but not in blood specimens from a vast cohort of paediatric control subjects. These data strongly support an involvement of CD30 T cells in the immune processes which take place at the level of lymphoid organs during the acute phase of KD.
