Minimally invasive adrenalectomy ­ Operative and perioperative results of transperitoneal and retroperitoneal adrenalectomies performed at the University of Szeged Department of Surgery during 23 years / Minimálisan invazív adrenalectomia - 23 év alatt végzett transperitonealis és retroperitonealis adrenalectomiák operatív és perioperatív eredményei a Szegedi Tudományegyetem Sebészeti Klinikán

Aim. Our goal was to evaluate operative and perioperative data of retroperitoneal (RP) and transperitoneal (TP) adrenalectomies performed at the University of Szeged Department of Surgery. Patients and method. During a retrospective cohort study including 174 adrenalectomies (28 RP; 146 TP) performed between 1998 and 2021, the following parameters were evaluated: rate of previous abdominal surgeries, conversion rate, operative time, intraoperative blood loss, tumor size, histology, hospital stay, early and late complications. Results. With significantly higher rate of previous abdominal surgeries [TP vs RP: 68 (46.57%) vs 4 (14%) P = 0.0021], there was no markable difference in conversion rate [TP vs RP: 7 (4.79%) vs 5 (18%), P = 0.312]. Significantly larger tumours were removed with TP (TP vs RP: 58.05 vs 34.8 mm, P = 0.016), with no markable difference in intraoperative blood loss (TP vs RP: 67.85 vs 50.2 ml, P = 0.157). Operative time was significantly shorter in TP (TP vs RP: 86.3 vs 134.5 min; P = 0.024). The most frequent histology was adenoma (TP vs RP: n = 95; 65.06% vs 64.3%). Pheochromocytoma occurred in 11 (7.53%) and 5 (17.8%) cases in TP and RP, respectively. We found no significant difference in hospital stay (TP vs RP: 5.125 vs 4.61 day; P = 0.413). Five- and 2 cases of early complications were seen in TP (splenic injury, postoperative fever, severe intraoperative bleeding, severe hypokalemia, surgical site infection) and RP (2 severe intraoperative bleeding), respectively. One lethal case of ventricular fibrillation and one delayed complication (postoperative abdominal wall hernia) were observed in TP. Conclusions. Both TP and RP are safe and simply reproducible minimally invasive techniques. According to our observation, RP adrenalectomy seems to be reserved for smaller lesions, while TP proves to be successful in removing enlarged and also malignant lesions with significantly shorter operative time.

Successful surgical treatment of a rare, large adrenal hemangioma / Ritka elofordulású, nagy méretu mellékvese-haemangioma sikeres sebészi kezelése.

Összefoglaló. A mellékvese-haemangiomák ritkán eloforduló, nehezen diagnosztizálható elváltozások, melyek sebészi eltávolítása gyakran nagy fokú technikai jártasságot igényel. Vizsgálatunkban egy 69 éves nobeteg esetét ismertetjük, akinél fogyás és hypertonia miatt végzett kivizsgálás mellékvesecisztát feltételezett, valamint felvetette adrenocorticalis carcinoma jelenlétét. A preoperatív kivizsgálás során (CT és MRI) a felmerülo malignitás miatt sebészi eltávolítás vált szükségessé. A kezdeti laparoszkópos transperitonealis technikát követoen a bonyolult elhelyezkedés, illetve vérzés miatt kis méretu, paramedián metszésbol konvertáltunk, és bal oldali nyitott adrenalectomiát végeztünk, valamint a vese caudalis részérol egy folyadéktartalmú képletet távolítottunk el. A szövettani feldolgozás a vese középso harmadának magasságából reszekált cisztát, valamint a cranialis lokalizációról eltávolított, ritka elofordulású mellékvese-haemangiomát igazolt. A ritkán eloforduló és többnyire bizonytalan preoperatív diagnózissal bíró mellékvese-haemangiomák sebészi eltávolítása nagy méretük, kompresszióra való hajlamuk, valamint malignitást utánzó megjelenésük miatt is indokolt. A laparoszkópos transperitonealis adrenalectomia extra nagy méretu (>10 cm ) és malignus tumorok, illetve nagy méretu haemangiomák eltávolítására is alkalmas eljárás. A mellékvese-haemangiomák sebészi reszekciója nagyfokú körültekintést igényel, megnövekedett vérzéshajlamuk, valamint a gyakori, nagyerekhez való közeli elhelyezkedés miatt a konverzió veszélye is jelentosen növekszik.

We herein describe the case of a 69-year-old female patient initially presented with weight loss and hypertension. Preoperative Computed Tomography (CT) and magnetic resonance imaging (MRI) confirmed the presence of an adrenal cyst and possible adrenocortical carcinoma requiring surgical intervention. After initial laparoscopic transperitoneal approach, conversion to open surgery through a small paramedian incision was carried out due to the lesion's problematic location and continuous intraoperative bleeding. Open adrenalectomy along with the removal of a fluid-bearing lesion from the caudal pole of the kidney was performed. Histology confirmed a cyst removed from the mid-third, and a rare occurring adrenal hemangioma from the cranial part of the kidney. Adrenal hemangiomas usually bear uncertain preoperative diagnosis. Surgical removal becomes necessary in case of increasing size, potential to compress neighbouring structures and possible malignancy. Laparoscopic transperitoneal adrenalectomy is a feasible approach for the removal of extra large (>10 cm) and even malignant lesions as well as for large hemangiomas. Surgery of adrenal hemangiomas require a high level of caution, moreover, their potential for bleeding and frequent vicinity to nearby vascular structures may increase the need for open surgery.
