Analysis of poor outcomes after laparoscopic adjustable gastric banding.

BACKGROUND: Recent studies document excess weight loss (EWL) of more than 50% with the laparoscopic adjustable gastric band (LGB). This study reviews the LGB experience at an urban academic center in terms of complications, reoperative rates, and comorbidities. METHODS: In this study, 144 consecutive patients undergoing LGB were prospectively reviewed. Data were collected including weight, body mass index (BMI), excess weight loss (EWL), comorbidities, and complications. Demographics were analyzed using a t-test. Linear regression was used to analyze the relationship of BMI, race, and age to EWL at 12 months. RESULTS: The study participants were 130 women with a mean age of 43 ± 11 years, a mean weight of 127.1 kg ± 20.5 kg, and a mean BMI of 45.6 ± 6.1. The mean follow-up period was 16 months. The mean EWL was 20% ± 14% at 6 months (n = 118), 26% ± 16% at 12 months (n = 106), 30% ± 20% at 18 months (n = 68), and 34% ± 23% at 24 months (n = 43). Patients with a BMI higher than 50 kg/m(2) had a lower EWL at 12 months than patients with a BMI lower than 50 kg/m(2) (P = 0.00005). The mean EWL at 12 months was significantly less for African Americans than for Caucasians (P = 0.0046; 95% confidence interval [CI] 3-15%). Patients older than 50 years had a lower EWL, but the difference was not statistically significant (P = 0.07). Complete and partial resolution of comorbidities occurred for 10% and 4% of the patients, respectively. Removal of the band with revision to a sleeve gastrectomy for inadequate EWL was required for 14 patients (11.5%). Complications occurred for 8% of the patients (n = 15) including port flipping, stoma obstruction, tube disconnection, port infections, dysphagia, and band slippage. Overall, 16.7% of the patients (n = 24) required reoperation. CONCLUSION: After LGB, a majority of the patients failed to achieve a 50% EWL, and 16.7% required reoperation. Laparoscopic adjustable gastric banding may not be the optimal bariatric procedure for patients older than 50 years, patients with a BMI higher than 50 kg/m(2), or African Americans.

Laparoscopy for stage IV melanoma in two organs.

Metastatic melanoma remains a disease associated with poor outcomes. Traditionally, surgical intervention plays a minimal role in its treatment. However, more recent studies document that complete surgical resection of distant metastases is associated with 5-year survival rates of 15% to 30%. These rates are greater than that reported for single-agent or combination chemotherapy, biologic agents or immunotherapy. This case report outlines a unique presentation of stage IV melanoma within the gastrointestinal tract located in 2 different organs. On the basis of the patient's clinical findings, laparoscopic surgery was performed for palliation of intestinal obstruction and bleeding. This approach resulted in less postoperative pain, earlier mobilization, and a faster return to daily activities. To our knowledge, this case details the only known account that uses a laparoscopic approach to palliate stage IV melanoma at 2 synchronous sites; the stomach and small bowel. The literature regarding the treatment of metastatic melanoma is also briefly reviewed.

Laparoscopic resection of a retroperitoneal cystic lymphangioma in an adult.

Cystic lymphangiomas are rare, benign anomalies of the lymphatic system. More than 95% of cystic lymphangiomas occur in the head, neck, and axilla with only 1% in the retroperitoneum. Most of these cases are diagnosed by the second year of life with only a handful of adult cases. Once a symptomatic cystic lesion of the abdomen or retroperitoneum is diagnosed, treatment usually consists of surgical excision. Traditionally, surgery requires a laparotomy. This paper describes a patient with a retroperitoneal cyst who underwent a successful laparoscopic resection. The etiology and management of adult retroperitoneal cysts are reviewed as well.

Laparoscopic sleeve gastrectomy for linear scleroderma.

Linear scleroderma is a rare type of autoimmune connective-tissue disorder and is one of five known types of localized, nonsystemic scleroderma. This type of localized scleroderma affects the skin and subcutaneous tissues and induces extensive fibrosis and atrophy of the affected limbs. The disease is, characteristically, a unilateral phenomenon and usually affects the lower extremities. Due to its underlying pathophysiology, linear scleroderma is rarely associated with morbid obesity. This article documents the case of a 45-year-old female with a 35-year history of unilateral linear scleroderma, who subsequently developed morbid obesity of her contralateral side. Due to her linear scleroderma, she was unable to exercise effectively and developed hemiobesity associated with arthritis, lower back pain, and hypercholesterolemia. Based on her hemiobesity and associated comorbidities, she underwent a laparoscopic sleeve gastrectomy. Postoperatively, she has lost 20 kg or 75% of her excess weight, with a resolution of joint and back pain and hypercholesterolemia at 12-month follow-up. This article describes a unique application for a sleeve gastrectomy in the setting of linear scleroderma and hemiobesity.
