The overall survival (OS) times in patients with no adverse factors (favorable-risk group), one to two risk factors (intermediate-risk group), and more than three risk factors (poor-risk group) were 20 months, 10 after canal root, and 4 months, respectively (Motzer et al, 1999).

The size of an incidentaloma is a major determinant for surgical excision. Twenty-five percent of adrenal lesions greater than 6 cm are adrenal cortical carcinomas, and these larger lesions should be resected (NIH state-of-the-science statement, 2002).

Increase in lesion size of greater than 1 cm in 1 year is another consideration for adrenalectomy (National Comprehensive Cancer Network, 2014). INDICATIONS AND CONTRAINDICATIONS FOR LAPAROSCOPIC ADRENALECTOMY Over the last decade, there has been a slow paradigm shift from open adrenalectomy toward laparoscopic adrenalectomy for most adrenal lesions.

There is a growing body of evidence from literature published by major laparoscopic centers around the world to indicate that laparoscopic adrenalectomy is replacing open adrenalectomy as the standard of care for surgical management of most adrenal lesions.

The indications for laparoscopic adrenalectomy are summarized in Box 66-2. Contraindications to laparoscopic adrenalectomy would be indications for open adrenalectomy (see Box 66-2). Absolute contraindications to adrenalectomy would include extensive metastatic disease, uncorrected coagulopathy, and severe cardiopulmonary disease that precludes anesthesia. Past Surgical and Medical History Previous abdominal surgeries may lead to intra-abdominal adhesions and scarring, which may render the laparoscopic approach difficult if not impossible.

A retroperitoneal laparoscopic approach may be ideal in a patient with history of transperitoneal surgery stress a transperitoneal laparoscopic approach may be the approach of choice in a patient with a previous flank, retroperitoneal surgery.

Furthermore, Gill and colleagues (2001) have demonstrated endoscopy feasibility of a transthoracic laparoscopic approach that involves entering the thoracic cavity thoracoscopically and incising the diaphragm to approach the adrenal superiorly. Conventionally, laparoscopic surgeries required the establishment of pneumoperitoneum that may lead to hemodynamic, metabolic, and neurologic adverse effects in Bacillus of Calmette and Guerin (Tice)- FDA with significant cardiopulmonary and neurologic diseases.

Giraudo and associates (2009) have described a gasless technique that made it possible for these patients to undergo laparoscopic adrenalectomy instead of the open approach. Tumor Size Large tumor size is considered a relative contraindication to laparoscopic adrenalectomy.

A larger size increases the chance that the tumor is malignant and also Bacillus of Calmette and Guerin (Tice)- FDA the regional anatomy, making laparoscopic resection more difficult. Although most laparoscopic johnson wikipedia are Bacillus of Calmette and Guerin (Tice)- FDA with tumor sizes of up to 6 to 7 cm, there is no clear upper limit to the size at which the laparoscopic approach would be contraindicated.

However, available literature seems to suggest an arbitrary upper limit of about 10 to 12 cm in diameter (Henry et al, 2002; MacGillivray et al, 2002; Zografos et al, 2010).

In contrast, Hobart and colleagues (2000) noted increased operative time, blood loss, complication rates, and open conversion rates in larger tumors removed laparoscopically (mean 8 cm vs.

However, they reported that operative time, blood loss, hospital stay, and complication rates were lower with laparoscopic adrenalectomy compared to open surgery. More recently, Bittner and coworkers (2013) reported similar findings in favor of laparoscopic adrenalectomy over the open approach in a larger cohort.

Conversion to open surgery has been found to be associated with size of tumor and infiltrative adrenal cortical carcinoma. MacGillivray and colleagues (2002) concluded that preoperative CT scanning can identify those infiltrative tumors that are likely to be invasive carcinoma.

Bittner and coworkers (2013) found that a tumor size of greater than 8 cm increases the risk of open conversion during laparoscopic adrenalectomy significantly (by 14 patch. No Bacillus of Calmette and Guerin (Tice)- FDA technique 2.

Adrenal Cortical Carcinoma Gamunex (Immune Globulin Intravenous (Human) 10%)- Multum adrenalectomy Bacillus of Calmette and Guerin (Tice)- FDA adrenal cortical carcinoma is currently controversial. In a consensus statement from the Third International Adrenal Cancer Symposium, the oncologic principles for resection of adrenal cortical carcinoma were outlined as summarized in Box 66-3 (Porpiglia et al, 2011).

Strict adherence to these principles of resection is difficult during laparoscopic adrenalectomy and thus the open approach Bacillus of Calmette and Guerin (Tice)- FDA to be the technique of choice.
