Retroperitoneal approach in laparoscopic adrenalectomy

Recently, the retroperitoneal laparoscopic approach has been described as advantageous in avoiding the respiratory and hemodynamic effects of CO₂ pneumoperitoneum and giving direct access without the need to move abdominal organs. Forty-two laparoscopic adrenalectomies (LpA) were performed in 36 patients with a variety of adrenal disorders, including 9 patients with nonfunctioning tumors, 11 patients with aldosterone adenoma, 10 patients with Cushing's adenoma, and 6 patients with Cushing's disease. Twenty-two adrenalectomies were performed using the transperitoneal approach (TLpA), and 20 via the retroperitoneoscopic approach (RLpA). Arterial blood samples, mean arterial pressure, heart rate, and clinical parameters were evaluated. At the end of the operation, the PaCO₂, PetCO₂, and base deficit all increased significantly in both retroperitoneal and transperitoneal CO₂ insufflation compared with basal values. Arterial pH decreased significantly in both TLpA and RLpA groups. All clinical parameters evaluated (operation time, analgesic dosing requirements, hospital stay, and the days until return to normal activity) were similar in the TLpA and RLpA approaches. Two patients in the TLpA (10.5%) group and two patients in the RLpA (10%) group needed conversion to open surgery. This study shows the safety and efficacy of laparoscopic adrenalectomy via the transperitoneal or retroperitoneal route in patients with a variety of adrenal disorders. The retroperitoneoscopic approach could be the primary choice in patients with previous abdominal surgery. Received: 3 April 1997/Accepted: 26 August 1997     

Retroperitoneoscopic nephron-sparing surgery of renal tumor using a microwave tissue coagulator without renal ischemia: comparison with open procedure

PURPOSE: It is ideal to use not a transperitoneal but a retroperitoneal approach for both open and endoscopic partial nephrectomy. We compared the results of retroperitoneoscopic nephron-sparing surgery for small renal tumors using a microwave tissue coagulator without renal pedicle clamping with those of a retroperitoneal open procedure. PATIENTS AND METHODS: Between 1996 and 2002, eight patients with small renal tumors underwent retroperitoneoscopic partial nephrectomy without renal ischemia, and nine patients with small renal tumors underwent open partial nephrectomy via a retroperitoneal approach. Both groups were operated on using a microwave tissue coagulator. RESULTS: Retroperitoneoscopic partial nephrectomy without renal ischemia was performed without any major or minor complications in any patient. The mean operation time for retroperitoneoscopic surgery was significantly longer than that for open partial nephrectomy (221.9 minutes v 145.9 minutes; P = 0.0004). However, the mean estimated blood loss for retroperitoneoscopic surgery was less than that for open partial nephrectomy (137.5 mL v 334.8 mL; P = 0.012). In addition, the retroperitoneoscopic group seemed to recover more rapidly than the open surgery group. CONCLUSIONS: Retroperitoneoscopic nephron-sparing surgery of small renal tumors using a microwave tissue coagulator without renal ischemia is feasible as minimally invasive procedure. It results in saving renal function, minimal blood loss, and rapid recovery.

From laparoscopic training on an animal model to retroperitoneoscopic or coelioscopic adrenal and renal surgery in human

So far, laparoscopic approaches to kidney and adrenal have been limited because of their retroperitoneal location. We here report eight renal and adrenal endoscopic procedures performed in seven patients: two adrenalectomies for hyperaldosteronism, one adrenalectomy for isolated metastasis from an adenocarcinoma of the lung; two nephrectomies for end-stage infected hydronephrosis, two partial nephrectomies for small circumscribed lesions of the kidney, and one endoscopic resection for pain relief of a voluminous cyst at the kidney. The approach was transperitoneal in two cases and retroperitoneal in five cases using the retropneumoperitoneum insufflation technique. One patient was operated by a combined approach using the retro- and transperitoneal routes. All procedures were successfully completed endoscopically. The retroperitoneoscopic approach of the kidney is safe and does not interfere with the peritoneal organs. Its working space is tenuous, but allows a direct access on the kidney with good exposure of its pedicle. For adrenal surgery, the retroperitoneoscopic dissection is more difficult, because movements of instruments are often impaired by the closeness of the costal margin and the iliac crest. However, in case of difficulties we found it very convenient to switch from a retroperitoneal endoscopic approach to a combined coelioscopic and retroperitoneoscopic operation. Far from excluding each other, both approaches are complementary, particularly for difficult situations (i.e., previous peritoneal or retroperitoneal surgery).

Prospective randomized comparison of transperitoneal versus retroperitoneal laparoscopic radical nephrectomy

PURPOSE: We report on a prospective randomized comparison of transperitoneal versus retroperitoneal laparoscopic radical nephrectomy for renal tumor. MATERIALS AND METHODS: Between June 1999 and June 2001, 102 consecutive eligible patients with a computerized tomography identified renal tumor were prospectively randomized to undergo either a transperitoneal (group 1, 50 patients) or retroperitoneal (group 2, 52 patients) laparoscopic radical nephrectomy with intact specimen extraction. Exclusion criteria for the study included body mass index greater than 35 or a history of prior major abdominal surgery in the quadrant of interest. Both groups were matched regarding age (63 versus 65 years, p = 0.69), BMI (29 versus 28, p = 0.89), American Society of Anesthesiologists class (2.7 versus 2.8, p = 0.37), laterality (right side 46% versus 48%, p = 0.85) and mean tumor size (5.3 versus 5.0 cm, p = 0.73). RESULTS: All 102 procedures were technically successful without the need for open conversion. Compared to the transperitoneal approach, the retroperitoneal approach was associated with a shorter time to renal artery control (91 versus 34 minutes, p <0.0001), shorter time to renal vein control (98 versus 45 minutes, p <0.0001) and shorter total operative time (207 versus 150 minutes, p = 0.001). However, the transperitoneal and retroperitoneal approaches were similar in terms of estimated blood loss (180 versus 242 cc, p = 0.13), hospital stay (43 versus 45 hours, p = 0.55), intraoperative complications (10% versus 7.7%, p = 0.30), postoperative complications (20% versus 13.5%, p = 0.14) and postoperative analgesia requirements (27 versus 26 mg MSO4 equivalent p = 0.13). Pathology revealed renal cell carcinoma in 84% and 75% of cases, respectively, with no positive surgical margin in any case. CONCLUSIONS: Laparoscopic radical nephrectomy can be performed efficiently and effectively with the transperitoneal or the retroperitoneal approach. While renal hilar control and total operative time may be quicker with retroperitoneoscopy, the approaches are similar in terms of other patient outcomes evaluated.     

Transperitoneal laparoscopy into the previously operated abdomen: effect on operative time,length of stay and complications

PURPOSE: We evaluated the effect of previous abdominal surgery on perioperative outcomes in patients undergoing a renal/adrenal laparoscopic procedure via a transperitoneal approach. MATERIALS AND METHODS: Renal/adrenal laparoscopic procedures via a transperitoneal approach were assessed. Medical records were reviewed to obtain operative and perioperative data. RESULTS: Of the 190 patients 76 (40%) had previously undergone abdominal surgery. Patients with versus without an earlier abdominal operation had a longer mean hospital stay (3.8 versus 2.6 days, p = 0.002) but not longer median operative room time (median 220 versus 210 minutes, p >0.05). Operative and major complication rates were greater in patients with previous operations (16% versus 4%, p = 0.009 and 16% versus 5%, p = 0.022, respectively). Access and total complication rates were not altered (4% versus 2% and 33% versus 24%, respectively, p >0.1). An upper midline scar/ipsilateral upper quadrant scar was associated with a greater access complication rate (12% versus 0%, p = 0.029) but not a higher operative complication rate (21% versus 13%, p = 0.502). Multiple logistic regression confirmed that previous abdominal surgery was the only factor associated with operative complications. CONCLUSIONS: Previous open abdominal operation increased the risk of operative and major complications, which most likely resulted in increased length of stay. The location of the scar impacted the access complication rate. Patients who have undergone previous open surgical procedures should be counseled on the greater risk of complications if the transperitoneal route is elected. Alternatively a retroperitoneal approach may be used.     

RETROPERITONEOSCOPIC SURGERY IS NOT ASSOCIATED WITH INCREASED CARBON DIOXIDE ABSORPTION

PURPOSE: Previous studies have suggested that retroperitoneal laparoscopy is associated with greater carbon dioxide absorption and related postoperative morbidity, such as subcutaneous emphysema and pneumothorax. We prospectively compared the effects of carbon dioxide absorption during transperitoneal and retroperitoneal laparoscopic renal and adrenal surgery at our institution. MATERIALS AND METHODS: Data were collected prospectively on 51 patients who underwent laparoscopic renal (26) or adrenal (25) surgery via the transperitoneal (18) or retroperitoneal (33) approach from September 1997 to February 1998. RESULTS: There was no significant difference in carbon dioxide elimination in patients who underwent transperitoneal laparoscopy compared to retroperitoneoscopy at any interval. Subcutaneous emphysema occurred in 12.5% of the transperitoneal and 45% of the retroperitoneal group (p = 0.09). Patients with subcutaneous emphysema had greater carbon dioxide elimination during the first 2.5 hours of insufflation compared to those without subcutaneous emphysema and, thereafter, carbon dioxide elimination decreased to baseline. CONCLUSIONS: In contrast to previous reports our prospective nonrandomized study suggests that retroperitoneoscopy is not associated with greater carbon dioxide absorption compared to transperitoneal laparoscopy. Patients with subcutaneous emphysema exhibited only transient increases in carbon dioxide absorption above control levels.     

International Consultation on Urological Diseases and European Association of Urology International Consultation on Minimally Invasive Surgery in Urology: laparoscopic and robotic adrenalectomy

The aim of this study was to provide an evidence‐based systematic review of the use of laparoscopic and robotic adrenalectomy in the treatment of adrenal disease as part of the International Consultation on Urological Diseases and European Association of Urology consultation on Minimally Invasive Surgery in Urology. A systematic literature search (January 2004 to January 2014) was conducted to identify comparative studies assessing the safety and efficacy of minimally invasive adrenal surgery. Subtopics including the role of minimally invasive surgery for pheochromocytoma, adrenocortical carcinoma (ACC) and large adrenal tumours were examined. Additionally, the role of transperitoneal and retroperitoneal approaches, as well as laparoendoscopic single‐site (LESS) and robotic adrenalectomy were reviewed. The major findings are presented in an evidence‐based fashion. Large retrospective and prospective data were analysed and a set of recommendations provided by the committee was produced. Laparoscopic surgery should be considered the first‐line therapy for benign adrenal masses requiring surgical resection and for patients with pheochromocytoma. While a laparoscopic approach may be feasible for selected cases of ACC without adjacent organ involvement, an open surgical approach remains the ‘gold standard’. Large adrenal tumours without preoperative or intra‐operative suspicion of ACC may be safely resected via a laparoscopic approach. Both transperitoneal and retroperitoneal approaches to laparoscopic adrenalectomy are safe. The approach should be chosen based on surgeon training and experience. LESS and robotic adrenalectomy should be considered as alternatives to laparoscopic adrenalectomy but require further study.

COMPARISON OF 3 SURGICAL APPROACHES TO LAPAROSCOPIC ADRENALECTOMY: A NONRANDOMIZED, BACKGROUND MATCHED ANALYSIS

PURPOSE: To clarify the characteristics of surgical approaches to laparoscopic adrenalectomy we performed background matched analysis of clinical outcomes of the 3 approaches. MATERIALS AND METHODS: From February 1992 to July 2000 we performed 118 laparoscopic adrenalectomies in 115 patients with adrenal tumors. For these operations we used the anterior transperitoneal approach in 46 patients, the lateral transperitoneal approach in 32 and the lateral retroperitoneal approach in 40. RESULTS: To exclude the learning curve effect we eliminated our initial 20 patients treated with the anterior transperitoneal approach. To allow background matching of the 3 groups we also excluded 14 patients with tumors more than 5 cm., 6 who underwent conversion to open surgery and 1 patient who required 5 days of bed rest for retroperitoneal hematoma caused by bleeding from a trocar port. The final analysis included 16, 25 and 36 cases managed via the anterior transperitoneal, lateral transperitoneal and lateral retroperitoneal approach, respectively. Average operative time was significantly shorter for the lateral transperitoneal approach. Postoperative recovery was not significantly different in the lateral transperitoneal and lateral retroperitoneal groups. Postoperative complications included mild paralytic ileus in 2 patients and shoulder tip pain, probably peritoneal irritation due to carbon dioxide insufflation and bowel preparation, in 4 in the transperitoneal groups. Our results imply that the easiest procedure is the lateral transperitoneal approach but the lateral retroperitoneal approach is slightly less invasive. CONCLUSIONS: Although it is important to remember that this study was not a prospective randomized trial and, thus, had from certain biases, we believe that if a tumor is more than 5 cm. and/or the surgeon is not yet skilled in laparoscopic adrenalectomy, the lateral transperitoneal approach is the most suitable method. If the surgeon has performed at least 20 operations, the adrenal tumor is unilateral and the lesion is less than 5 cm., the lateral retroperitoneal approach seems to be more suitable because of its minimally invasive nature. The lateral retroperitoneal approach is also preferred in patients with a history of upper abdominal surgery. With improvements in technique and new instruments the time required for the lateral retroperitoneal approach has been significantly decreased.     

Transperitoneal laparoscopic adrenalectomy: outline of the preoperative management, surgical approach, and outcome

The laparoscopic approach to the adrenal gland has evolved to be the gold standard for most cases of adrenal conditions requiring surgical treatment. There is general consent about the safety, efficacy, and reproducibility of laparoscopic adrenal surgery. Compared to the open surgery, significant advantages with regard to shorter hospitalization time, decreased postoperative morbidity, improved cosmetics, and quicker convalescence are evident. The anatomic location of the adrenal gland led to the development of various approaches, including lateral transperitoneal, anterior transperitoneal, lateral retroperitoneal, posterior retroperitoneal, and even transthoracic approaches. The lateral transperitoneal approach is the technique most frequently used for laparoscopic adrenalectomy. A large operative field provides good orientation and visualization of familiar landmarks known from open surgery. In particular in the early learning curve this represents an advantage of the transperitoneal laparoscopic approach. This article describes in detail the indications, contraindications, preoperative evaluation, surgical technique, management of intraoperative complications, and outcome after lateral transperitoneal adrenalectomy.     

Laparoscopic radical nephrectomy

Laparoscopic radical nephrectomy has gained in popularity as an accepted treatment modality for localized renal cell carcinoma at many centers worldwide. Laparoscopic radical nephrectomy may be performed via a transperitoneal or retroperitoneal approach. Mostly, the transperitoneal approach is used. Current indications for laparoscopic radical nephrectomy include patients with T(1)-T(3a)N(0)M(0) renal tumors. Herein, transperitoneal as well as retroperitoneal laparoscopic approaches are described. Surgical outcomes and complications from published series are reviewed with comparison to open surgery. Special related concerns as oncologic principles, organ retrieval, lymphadenectomy, and concomitant adrenalectomy are addressed. In conclusion, laparoscopic radical nephrectomy is now established with considerable advantages; decreased postoperative morbidity, decreased analgesic requirements, improved cosmesis, shorter hospital stay and convalescence. Although no long-term follow-up is available, short and intermediate follow-up results confirm the effectiveness of laparoscopic radical nephrectomy.     

Retroperitoneoscopic partial nephrectomy by using microwave tissue coagulation

Partial nephrectomy is widely accepted as a treatment for small renal cell carcinoma. However, the laparoscopic approach has not yet been considered as a standard procedure. We reviewed our 13 retroperitoneoscopic partial nephrectomies and 11 conventional open partial nephrectomies. We have used microwave tissue coagulation for retroperitoneoscopic surgery without renal pedicle clamping between December 1999 and May 2003. The mean operating time for the retroperitoneoscopic group was not significantly longer than that for conventional open surgery group (183 minutes vs 194 minutes). However, the mean blood loss for the retroperitoneoscopic group was less than that for the open group (143 ml vs 512 ml). Histologic evaluation revealed renal cell carcinoma in 10 patients, angiomyolipoma in 2 patients, and lymphoangiomyomatosis in one patient for retroperitoneoscopic group and renal cell carcinoma in 11 patients for the conventional open surgery group. In addition, when compared with the historical control that had undergone conventional partial nephrectomy, laparoscopic cases had significantly shorter postoperative times to oral intake, ambulance, and discharge from hospital. Bowel injury, massive bleeding, urine leakage, and atelectasis occurred in one case each in retroperitoneoscopic surgery. Retroperitoneoscopic surgery in the case of massive bleeding was converted to open surgery. On the other hand, urine leakage and postoperative hemorrhage occurred in one case each in conventional open surgery. Retroperitoneoscopic partial nephrectomy by using microwave tissue coagulation is a useful and less invasive method, whereas this procedure is more challenging than open partial nephrectomy in terms of complications.     

Prospective, randomized comparison of transperitoneal versus retroperitoneal laparoscopic adrenalectomy

PURPOSE: We report a prospective, randomized comparison of transperitoneal laparoscopic adrenalectomy (TLA) vs retroperitoneal laparoscopic adrenalectomy (RLA) for adrenal lesions with long-term followup. MATERIALS AND METHODS: Between December 1997 and November 1999, 57 consecutive eligible patients with surgical adrenal disease were prospectively randomized to undergo TLA (25) or RLA (32). Study exclusion criteria were patient age greater than 80 years, body mass index greater than 40, bilateral adrenalectomy and significant prior abdominal surgery in the quadrant of interest. Mean followup was 5.96 years in the 2 groups. RESULTS: The groups were matched in regard to patient age (p = 0.84), body mass index (p = 0.43), American Society of Anesthesiologists class (p = 0.81) and laterality (p = 0.12). Median adrenal mass size was 2.7 cm (range 1 to 9) in the TLA group and 2.6 cm (range 0.5 to 6) in the RLA group (p = 0.83). TLA was comparable to RLA in terms of operative time (130 vs 126.5 minutes, p = 0.64), estimated blood loss (p = 0.92), specimen weight (p = 0.81), analgesic requirements (p = 0.25), hospital stay (p = 0.56) and the complication rate (p = 0.58). One case per group was electively converted to open surgery. Pathology data on the intact extracted specimens were similar between the groups. Averaged convalescence was 4.7 weeks in the TLA group and 2.3 weeks in the RLA group (p = 0.02). During a mean followup of 6 years 2 patients in the TLA group had a late complication (port site hernia). Mortality occurred in 5 patients, including 1 with TLA and 4 with RLA, during the 6-year followup. CONCLUSIONS: For most benign adrenal lesions requiring surgery laparoscopic adrenalectomy can be performed safely and effectively by the transperitoneal or the retroperitoneal approach.     

Laparoscopic nephrectomy: prediction of outcome in relation to the preoperative risk factors in two approaches

PURPOSE: The data on laparoscopic nephrectomy in Mansoura Urology & Nephrology Center were reviewed to identify the preoperative findings that may predict the need for conversion to open surgery. PATIENTS AND METHODS: One hundred sixty-three patients were subjected to transperitoneal laparoscopic nephrectomy, while 82 underwent retroperitoneal laparoscopic nephrectomy for benign renal diseases. The preoperative demographic data and laboratory and radiologic findings of these patients were correlated with failure rate of the laparoscopic procedure. RESULTS: The overall failure rate was 10.4% and 11% for the transperitoneal and retroperitoneal approach, respectively. Positive urine culture, renographic clearance of the removed kidney (>10 ml/min), and learning curve were independently associated with a greater risk of failure in patients undergoing transperitoneal nephrectomy. For the retroperitoneal approach, a positive urine culture, renographic clearance (> or =10 ml/min), and large kidney showed statistical significance. CONCLUSION: Preoperative data could be used as a predictor of laparoscopic nephrectomy outcome in patients with benign renal diseases. A more experienced surgeon should be selected for risky cases, bearing in mind the greater potential for early conversion to open surgery.
