Laparoscopic management of colonic lipomas: a case report and review of the literature.

Colonic lipomas are infrequent lesions, yet they are the second most common benign lesions of the colon after benign adenomatous polyps. Their treatment ranges from observation to segmental colectomy and has been a matter of debate since Bauer first reported them in 1757. With the advent of new technologies, therapeutic options now include observation, endoscopic removal, laparoscopic removal, and traditional open surgery. We present a case of colonic lipoma presenting with indeterminate symptomatology, its workup, treatment outcome, and a review of the current literature.

101 laparoscopic splenectomies for the treatment of benign and malignant hematologic disorders.

BACKGROUND: Laparoscopic splenectomy (LS) is the surgical approach of choice for patients with hematologic disorders requiring splenectomy. Patients with idiopathic thrombocytopenic purpura (ITP) have normal to slightly enlarged spleens and benefit the most from LS. METHODS: We reviewed the perioperative outcomes in 101 patients who underwent LS between May 1996 and December 2002. Patients were divided into three groups--ITP, other benign, and malignant hematologic disorders--and compared. RESULTS: The ITP patients (n = 48) had significantly smaller spleens and operative times compared with the other groups. Splenomegaly in the other benign (n = 23) and malignant hematologic disorders (n = 30) groups was responsible for higher open conversion rates and greater need for hand-assisted laparoscopic splenectomy (HALS). CONCLUSIONS: Laparoscopic splenectomy and HALS can be performed with good results for benign and malignant hematologic disorders. The benefits of HALS are similar to LS, so there should be a low threshold for HALS in patients with large spleens.

Intravenous methylene blue as an aid to intraoperative localization and removal of the adrenal glands during laparoscopic adrenalectomy.

BACKGROUND: We hypothesized that intravenous methylene blue will facilitate adrenal gland identification and resection during laparoscopic adrenalectomy. METHODS: Five mini-Hanford pigs were anesthetized and monitored per an approved Internal Review Board protocol. Timing of color changes in the adrenals was recorded after administering methylene blue at three different doses: 2.5 mg/kg, 5.0 mg/kg, and 7.5 mg/kg. The time required for laparoscopic adrenalectomy with and without methylene blue was recorded. RESULTS: No color change occurred after the 2.5 mg/kg dose. For the 7.5 mg/kg versus the 5.0 mg/kg dose there was a more rapid bluish color change (mean time, 1.89 minutes versus 3.45 minutes; P = 0.03) and a longer duration of bluish color change (mean time, 12.20 minutes versus 6.19 minutes; P = 0.01). Laparoscopic adrenalectomy using methylene blue resulted in a 34.5% faster median resection time (10.13 minutes versus 15.47 minutes). CONCLUSIONS: Methylene blue concentrates in the adrenal glands and facilitates identification and resection of the adrenal glands by a laparoscopic approach.
