Food residue granuloma mimicking metastatic disease on FDG-PET/CT.

A 31-year-old woman presenting with acute abdomen underwent an emergency Hartmann's procedure for fecal peritonitis due to perforated adenocarcinoma of the left colon. Shortly after a 7-month course of adjuvant chemotherapy, follow-up contrast-enhanced CT showed multiple peritoneal and hepatic nodules, showing focal intense and homogeneous FDG uptake on FDG-PET/CT, highly suspected for recurrence of disease. Excisional biopsy of the nodules revealed foreign body granulomas made up of alimentary materials surrounded by a fibrous wall. We report a unique case of a false-positive finding secondary to food residues mimicking metastatic disease on FDG-PET in a patient with colon cancer.

Laparoscopic splenectomy for atraumatic splenic rupture.

A traumatic splenic rupture (ASR) is a rare clinical entity. Several underlying benign and malignant conditions have been described as a leading cause. We report on a case of ASR in a 41-year-old man treated with laparoscopic splenectomy. Considering ASR as a life-threatening condition, a prompt diagnosis can be life saving.

Solid pseudopapillary tumor of the pancreas in children: report of a case and review of the literature.

Solid pseudopapillary tumor (SPT) of the pancreas is an infrequent neoplasm of low malignant potential, first described by Frantz in 1933 and representing less than 3% of all exocrine tumors. SPT is rare in children, accounting for 6% of all cases and shows different clinical features compared with adults. Here, a pediatric case is reported and a review of the Literature is provided. A 15-year-old girl with a 12 × 14 × 10 cm solid mass growing from the tail and the body of the pancreas, involving spleen, left adrenal gland and kidney, stomach and some bowel loops, was referred for surgical treatment. A distal pancreasectomy with splenectomy was performed. Histopathological examination revealed that the tumor was a 14-cm well-circumscribed solid mass, with pseudopapillary cell architecture, showing strong cellular immunoreactivity for alpha-1 antitrypsin, vimentin, neurone-specific enolase, progesterone receptors and in part to CD10 and CAM 5.2, but not to sinaptofisin and chromogranin. A 24-month post-surgical follow-up after successful surgical resection showed no evidence of recurrent disease. SPT shows different clinical features in childhood. High survival rates can be achieved in most cases, warranting aggressive treatments even in metastatic disease.

[Laparoscopic repair of incisional and ventral hernia]. / Trattamento laparoscopico delle ernie incisionali e ventrali della parete addominale.

The application of laparoscopic principles to ventral or incisional hernia repair has recently been shown to be a safe and effective alternative to open procedures. In this study we analyzed our recent experience with laparoscopic incisional-ventral hernia repair. The outcomes of 75 consecutive patients (January 2002 to July 2006) who underwent laparoscopic repair for incisional-ventral hernia were reviewed. Patient's demographics, hernia parameters, and intraoperative and postoperative data were collected. Of the 75 patients, 44 were females and 31 males. Mean age was 59.1 yrs (range 29-80 yrs). Mean BMI was 25.9 (range 19.4-36.7). Twenty-one patients had primary ventral hernias while 54 patients had an incisional hernia. Fifty-three patients had a single defect and 22 patients multiple defects. In 45 cases the incisional hernia was a primary hernia; in 4 cases it was a first recurrence; in 2 cases a 2nd recurrence; and in 3 cases a 3rd recurrence. The mean defect size was 52,7 cm2 (range 4-432). Laparoscopic hernia repair was successfully performed in 71 cases (94.7%). The mean mesh size was 211 cm2 (range 63-694). Mean operating time was 101 min (range 50-220 min). The mean hospital stay was 4.7 days. The postoperative morbidity rate was 14%. After a mean follow-up of 24.6 months (range 7-56) the recurrence rate was 7% (5/71). Laparoscopic repair of incisional-ventral hernias seems to be safe and effective. Medium-term outcomes were promising with a relatively low rate of conversion to open surgery, a low complication rate and a low risk of recurrence.
