Is there a role for a handheld gamma camera (TReCam) in the SNOLL breast cancer procedure?

BACKGROUND: Sentinel node and occult lesion localization (SNOLL) calls for a combination of two specific procedures: intraoperative detection of sentinel lymph node (SLN) and radio-guided occult lesion localization (ROLL). The safety and benefits of radio-guided localization in the surgical treatment of non-palpable breast cancer have been confirmed. The aim of this study was to evaluate the potential role for an intra-operative handheld tumor resection gamma camera (TReCam) in SNOLL procedures. METHODS: Fifteen patients were enrolled. The SNOLL procedure was performed in all patients with conventional lymphoscintigraphy (LS). TReCam was used to obtain nuclear imaging in the operating theater. Concordance between LS and TReCam images, duration of use and assessment of difficulties in data acquisition with TReCam were reported. RESULTS: Concordance for tumor localization between single-detector gamma probe and TReCam was excellent (15/15). The number of radioactive SLNs visualized between LS and TReCam was equivalent in 53.3% of cases (8/15). TReCam was considered to be very easy-to-use (12/15) or easy-to-use (3/15). Average duration of acquisition with TReCam was 4 minutes and 45 seconds for the SLN procedure, and 2 minutes and 10 seconds for lumpectomy. CONCLUSIONS: This study suggests that TReCam is easy-to-use and does not increase operative time. Its exact role in radio-guided surgery needs to be clearly defined in a larger study. However, its usefulness and benefits in radio-guided breast surgery seem to be promising.

Five-millimeter trocar site small bowel eviscerations after gynecologic laparoscopic surgery.

Trocar site hernia is a known complication after laparoscopic surgery, especially at 10-mm and larger port sites. Only a few cases of herniation through 5-mm port sites are reported in the literature. We describe 2 cases of bowel herniation and bowel obstruction through 5-mm port sites. The patients were 63 and 74 years old; both had endometrial cancer and underwent an uncomplicated hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy with peritoneal drains left at the lateral 5-mm port sites. Each patient presented symptoms of small bowel obstruction after which the drains were removed and were found to have evisceration through a laterally placed 5-mm port site. The bowel was reduced locally, and a segmental bowel resection was needed in 1 case. Bowel herniation can occur through the fascial defect after placement of a 5-mm port, especially if drains have been placed at the port site.
