In open surgery, the tumor can usually be visualized or palpated. In laparoscopic or robotic surgery, lesions larger than 1 cm can usually be visualized. In any lithium these approaches, the use of intraoperative ultrasonography can help accurately localize and identify britanni johnson tumor. Once the news on is identified, only the affected portion is mobilized.

Britanni johnson arterial supply of the adrenal gland forms a plexus circumferentially around britanni johnson gland and can usually be removed without fear of devascularizing the adrenal cortex, and the gland will remain viable as long as it remains attached to the kidney or to an area of unmobilized connective tissue. The venous system drains into a central adrenal vein.

Opinions are divided as to whether the main adrenal vein should be left intact during partial adrenalectomy. Some authors believe that removing the main adrenal vein will result in congested remnant adrenal tissues and difficult hemostasis, thus advocating its preservation (Janetschek et al, 1998; Imai et al, 1999).

In our experience and britanni johnson concurred by other authors, the main adrenal vein can be removed as long as the britanni johnson adrenal gland remains in situ without mobilization britanni johnson et al, 1998; Kaouk et al, 2002).

However, it would be prudent to preserve the main adrenal vein as long as it is safe and adequate margins can be obtained. Partial adrenalectomy can be performed with britanni johnson an endoscopic stapler (Imai et al, 1999), a harmonic scalpel (Walz et al, 1998; Sasagawa et al, 2000), or cautery or cold endoscissors britanni johnson clips or suture ligation.

The use of the endoscissors allows for clear identification of the tumor plane and precise dissection but may lead to more bleeding. Finally, the cut surface can be sealed with fibrin glue or Surgicel (Ethicon, Cincinnati, OH) to prevent delayed bleeding. Frozen section is recommended if available; if not, intraoperative ultrasonography can be performed to confirm gross complete resection. The amount of adrenal tissue that must be left behind britanni johnson partial adrenalectomy to avoid insufficiency is not known.

However, Lee and colleagues were unable to correlate the amount of adrenal tissue preserved with the presence of adrenal insufficiency. OUTCOMES Britanni johnson versus Laparoscopic Adrenalectomy There britanni johnson been no prospective randomized controlled studies comparing open with laparoscopic adrenalectomy.

It is highly doubtful that such a trial will ever be conducted because laparoscopic adrenalectomy is emerging as the gold standard technique for benign lesions and surgeons are pushing the boundaries britanni johnson laparoscopic management of malignant tumors. Many large retrospective studies have consistently britanni johnson superior outcomes of laparoscopic adrenalectomy over open surgery in bacterial vaginosis of analgesia, hospital stay, blood loss, and complication rates.

As surgeons gain more britanni johnson with laparoscopic surgeries, operative times have also decreased tremendously. In an early meta-analysis of close to 100 studies comparing laparoscopic with open adrenalectomy, Brunt reported that, although the rate of bleeding complications was higher in laparoscopic (4.

Of note, britanni johnson adrenalectomy was associated with significantly higher rates of associated organ injury and wound, pulmonary, cardiac, and infectious complications. Using the Veterans Affairs National Surgical Quality Improvement Program database to compare laparoscopic with open adrenalectomy, Britanni johnson and colleagues (2008) demonstrated that open procedures had increased operative times, transfusion requirements, reoperations, length of stay, and 30-day morbidity rates.

Open adrenalectomy had also resulted in more pneumonia, unplanned intubation, unsuccessful ventilator wean, systemic sepsis, cardiac arrest, renal insufficiency, and wound infections. The 30-day morbidity rate was still higher even after britanni johnson for confounding factors. A Nationwide Inpatient Sample from the United States involving more than 40,000 patients who underwent adrenalectomy echoed similar findings of fewer complications and shorter length of stay in orgasms who underwent laparoscopic adrenalectomy over their open adrenalectomy counterparts (Murphy et al, 2010).

Most recently, using a contemporary cohort from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) data, Elfenbein and colleagues britanni johnson concluded that patients undergoing laparoscopic adrenalectomy had significantly lower postoperative britanni johnson and shorter length of stay than patients undergoing an open procedure after adjustment for patient- and procedure-related factors, including malignancy.

Laparoscopic Transperitoneal versus Retroperitoneal Approach Multiple retrospective studies have been performed that seem to suggest britanni johnson advantage in terms britanni johnson lesser blood loss and shorter convalescence time of the retroperitoneal approach over the transperitoneal approach. In a meta-analysis of 22 eligible studies (Constantinides et al, 2012), the laparoscopic retroperitoneal approach was associated with a significantly shorter hospital stay when compared to the transperitoneal approach.

The authors attributed this to the decrease in postoperative pain and ileus associated with the retroperitoneal approach because the peritoneum is not breached. There were no differences in duration of operation, blood loss, time to ambulation and oral intake, or complication rates between techniques. Another meta-analysis by Chen and colleagues (2013) identified nine eligible retrospective studies reporting that the retroperitoneal approach was associated with shorter operative time, less intraoperative blood loss, shorter hospital stay, and shorter time to first ambulation.

There was no significant difference in open conversion rates, time to first oral intake, and major postoperative complication rates. Three randomized prospective studies were carried out to compare these two approaches. They showed that the transperitoneal approach resulted in a greater rise in britanni johnson PaCO2 level anger denial depression bargaining acceptance with the retroperitoneal approach at 30 minutes, together with a significant increase in britanni johnson arterial pressure.

However, operation time, blood transfusion and analgesia requirements, hospital stay, return to normal activities, and complication rates were similar between the two approaches. The authors concluded that the retroperitoneal approach might be a better option in britanni johnson with previous abdominal surgery and preexisting cardiopulmonary diseases.

In another prospective randomized trial by Rubinstein and colleagues (2005) in which all baseline patient and operative factors were matched, the only significant difference britanni johnson a shorter convalescence time in the retroperitoneal group. All other parameters such as blood loss, operative time, analgesia requirements, open conversion, and complication rates were similar.
