The role of laparoscopic surgery in isolated adrenal metastasis: our personal experience.

BACKGROUND: Over the past 25 years, mini-invasive adrenalectomy has become the treatment of choice for most adrenal diseases, and even adrenal malignancies in selected cases. The aim of this retrospective evaluation is to assess the effectiveness of laparoscopic adrenalectomy as a treatment of choice for adrenal metastases. METHODS: From 2008 to 2018, 207 laparoscopic adrenalectomies have been performed in our Department of Surgery. Among these, in 12 cases the indication to adrenalectomy was metastatic adrenal lesion. RESULTS: The right adrenal gland was removed in 8 cases and the left adrenal gland in 4 cases. A complete resection (R0) was achieved in all patients. The median operative time was 130.6 ± 23.3 min. The median postoperative hospitalization was 3.5±2.0 days. Only one patient showed postoperative grade II complications, according to Clavien-Dindo classification. All patients underwent follow-up at 6-12-18 months without showing disease recurrence. There was no intra and perioperative mortality. Conversion to laparotomic surgery has never been performed. Mean tumor size was 2.4 cm ±1.6 cm. CONCLUSIONS: Laparoscopic adrenalectomy for metastasis permits to achieve similar results to the open approach in term of oncological outcomes, but gaining in terms of postoperative hospitalization, intra and post-operative complications as well a greater patient compliance.

Current role of open surgery in adrenal tumors.

AIM: The aim of this retrospective evaluation is to assess the current role of open adrenalectomy, in particular in cases of adrenocortical carcinoma (ACC). MATERIALS AND METHODS: From January 2009 to May 2019, 26 open out of 233 adrenalectomies were performed in our Academic Department. Open adrenalectomy was performed by the anterior approach. A midline abdominal incision or a subcostal surgical incision was used to reach the peritoneal cavity. The resection was defined R0 if the margins of the sample were negative for malignancy. RESULTS: Open adrenalectomy was performed in 26 patients: 10 men and 16 women with a mean age of 61±25.3 years and a mean BMI of 28.4±2.9. The right adrenal gland was removed in 15 cases Romaand the left in 11 cases.We reported 18 diagnosis of malignant pathology. The other diagnosis concerned 5 cases of pheochromocytoma, 1 case of Cushing's disease and 2 cases of hyperaldosteronism. Mean tumor size was 7.7±5.5. Mean operative time was 160 min (range=110-205 minutes). Mean postoperative stay was 7±2 days. Only 3 (10%) patient showed postoperative grade II complications, according to Clavien-Dindo classification. Midline abdominal incision was used in 18 patients, subcostalsurgical incision in 5 patients and bilateral subcostal surgical incision in 3 patients. 3 right nephrectomy was necessary to remove the entire tumor mass. An en bloc R0 tumor resection was accomplished in all cases.There was no intra and perioperative mortality. All patients recovered well from surgery. The mean follow-up period was 15 (range=6-48) months. CONCLUSION: In conclusion, our retrospective study points out the role of open adrenalectomy as the treatment of choice in selected cases with known or suspected malignant adrenal tumors and with size greater than 12 cm.

[Comparison between two different mesh fixation methods in laparoscopic inguinal hernia repair: tacker vs. Synthetic cyanoacrylate glue.]

AIM: The aim of this retrospective study was to compare the results of two different mesh fixation methods in laparoscopic transabdominal preperitoneal hernioplasty (TAPP): tacker vs. synthetic cyanoacrylate glue. METHODS: The study group includes 70 patients with bilateral and monolateral recurrent inguinal hernia undergoing transabdominal preperitoneal repair (TAPP) in the period 2011-2013. A polypropylene mesh was fixed in group A (N.=35) with titanium tacks (EndoUniversal stapler, Covidien) or in group B (N.=35) with synthetic cyanoacrylate glue (Glubran-2, GEM). Patient outcome was assessed by the following variables: sex, mean age, ASA score, intra- and postoperative morbidity, hospitalization, postoperative acute and chronic pain, recurrence rate. The observation period was 24 months, with a mean follow-up of 10.5 months (range, 1-23) for Group A and 11 months (range, 2-24) for Group B. RESULTS: No difference between the two groups was observed with respect to mean operative time and hospitalization. In all cases, surgery was successfully concluded laparoscopically. Intraoperative complications occurred in 1 patient of the group A and consisted of a urinary bladder injury, which was immediately sutured. Postoperative complication rate was 5.7% (4 patients, of whom 3 in group A and 1 in group B). In each group we detected one recurrence within 6 (group A) and 18 months (group B) postsurgery; both patients were treated with a re-TAPP. Postoperative pain at 6 months from surgery, measured by visual analogue score (VAS), was reported by 4 patients in the group A and in no case of the group B (P=0.04). CONCLUSION: Data from this study demonstrate the advantages of synthetic cyanoacrylate glue for mesh fixation in laparoscopic transabdominal preperitoneal inguinal hernia repair, compared to titanium tacks. The use of this surgical glue was associated with a significantly reduced risk for developing chronic groin pain and a shortened hospital stay. Nevertheless, further studies with longer follow-up periods are needed to confirm our encouraging results.
