RESUMO
BACKGROUND: In case of Krukenberg tumor (KT) of gastric origin it is controversial and debated whether radical surgery in case of synchronous KT or metastasectomy in case of metachronous ones is associated with additional benefits. Role of perioperative treatments is unclear. METHODS: Among 2515 female patients who were diagnosed with gastric cancer between January 1990 and December 2012 from 9 Italian centers, 63 presented simultaneously or developed KT as recurrence. RESULTS: Thirty patients presented with synchronous KT, while 33 developed metachronous ovarian metastases during follow-up. The differences between the two groups were analyzed and compared. The median age of 63 patients was 48.0 years (range 31-71). Resection was possible in 53 patients (20 synchronous and 33 metachronous). Twelve patients in the synchronous group and 15 patients of the metachronous group underwent hyperthermic intraperitoneal chemotherapy after resection of KT. All of them underwent adjuvant chemotherapy after KT resection. The median survival for all population was 23 months (95 % confidence interval, 7-39 months). The median survival time in the metachronous group was 36 months, which was significantly longer than that in the synchronous group, 17 months, p < 0.0001. CONCLUSIONS: KT remains a clinical challenge for gastric cancer therapy. The extent of disease and feasibility of removal of the metastatic lesion must be carefully evaluated prior to surgery to define the patients group who could benefit most from a resection associated with perioperative treatments.

PURPOSE: Anal sphincter lesions represent the major cause of fecal incontinence, particularly in women. Sphincteroplasty with overlap is the traditional treatment, but a significant reduction in benefits within 5 years of surgery has been reported. More recently, sacral nerve stimulation has been suggested following sphincteroplasty or as primary treatment. METHODS: Overall, 24 women with fecal incontinence in the presence of anal sphincter lesions underwent sphincteroplasty (14 patients, mean age 47.6 +/- 15.6 years, range 26-70) or definitive implant of sacral nerve stimulation (10 patients, mean age 60.7 +/- 17.6 years, range 26-73), using identical selection criteria. At baseline, patients were studied with clinical evaluation, 3-dimensional endoanal ultrasound, and anorectal manometry (ARM), repeated at follow-up (median 60.0 months, range 6-96 in sphincteroplasty group; median 33.0 months, range 6-84 in sacral nerve stimulation group). RESULTS: At baseline, both groups presented similar characteristics. Two sphincteroplasty patients (14.3%) experienced relapse of fecal incontinence at 6 and 19 months after treatment, whereas good to excellent continence was observed in all of the sacral nerve stimulation patients. Compared to baseline, both groups showed a significant improvement in clinical parameters, and ARM data remained unchanged. In 12 of 14 sphincteroplasty patients, the repaired sphincter at endoanal ultrasound was found to overlap. At follow-up, comparison between sphincteroplasty and sacral nerve stimulation showed no significant differences in clinical and ARM parameters, if related to lesion of internal, external, or both sphincters. CONCLUSIONS: These data appear to confirm that sacral nerve stimulation could represent a valid alternative in the treatment of fecal incontinence patients presenting with sphincter lesion that was not preceded by sphincteroplasty.
