A novel study, textbook outcome in adrenalectomy: retrospective observational study in an endocrine surgical unit

Textbook outcome is a multidimensional quality management tool that uses a set of traditional surgical measures to reflect an "ideal" surgical result for a particular pathology. Retrospective study of all patients undergoing scheduled for adrenal tumors surgery at an endocrine surgery unit from January 2010-December 2022. The definition of Textbook Outcome were: R0 resection, no Clavien-Dindo ≥ IIIa complications, no prolonged stay (< P75), no readmissions, and no mortality in the first 30 days. The main objective was to analyze the rate of Textbook Outcome obtained. One hundred and five patients were included in the study. Textbook Outcome was achieved in 71.4%. Surgical approach (p < 0.001), Charlson scale (p = 0.031), American Society of Anesthesiologists Classification (p = 0.047) and surgical time (p < 0.001) were all significantly associated with the achievement of Textbook Outcome. The laparoscopic approach was associated as an independent factor with obtaining Textbook Outcome (OR:5.394; p = 0.016), as was surgical time (OR:0.986; p = 0.004). Textbook Outcome is a novel, useful, easy-to-interpret tool for measuring results in adrenal surgery. The laparoscopic approach is associated with a higher rate of "ideal" surgical results. The study was registered in the public accessible database clinicaltrials.gov with the ClinicalTrials.gov ID: NCT05888753.

[Transperitoneal laparoscopic adrenalectomy]

OBJECTIVES

To present our results with transperitoneal laparoscopic adrenalectomy after completion of 70 procedures.

MATERIAL AND METHODS

Between July 2002 and December 2010, transperitoneal laparoscopic adrenalectomy was performed in 70 patients with the following diagnoses: Conn syndrome (22 cases), nonfunctioning adenomas (18), Cushing syndrome (10), pheochromocytomas (7), myelolipomas (4), metastasis after treatment of primary nonadrenal tumors (6), ganglioneuroma (1), adrenal gland hematoma (1) and adrenal carcinoma (1). We describe the size, surgical and hospitalization times, blood loss, need for transfusion, surgical complications and rate of conversion to open surgery.

RESULTS

Of 70 patients, 35 were men and 35 women (1:1) with a mean age of 58.2 years (range, 82.2- 29.1). The most common site was left (58%) compared to right (42%). The mean size of the surgical specimen was 5.11 cm, mean surgical time was 119.2 minutes (50-240) and mean operative bleeding was 140.6 (30-800) cc. Only 3 patients required blood transfusion. The mean time until oral feeding was 17 hours, and the mean hospital stay was 4.3 (2-15) days. Complications included 2 cases of surgical infections, 1 of prolonged paralytic ileus, and 1 of splenic laceration and 1 of intestinal perforation which both which required reconversion to open surgery (4.28%).

CONCLUSIONS

Laparoscopic adrenalectomy is a safe procedure, with a low percentage of complications and a short hospital stay. The choice of this approach will depend on the surgeon's experience with the lesion etiology and size in each case.

[Development and evolution of laparoscopic adrenalectomy in an specialized team: from the beginning to the outpatient setting]

BACKGROUND

After the first reports in 1992, laparoscopic adrenalectomy (LA) has evolved technically until becoming the standard approach for the treatment of most of the adrenal gland diseases.

MATERIAL AND METHODS

Retrospective and descriptive study of 67 patients who underwent 68 LA between January-1998 and December-2008 in the Laparoscopic Surgery Unit of the General and Digestive Surgery Service in a third level hospital (only one case of bilateral LA). The group was divided in 2 periods, P-1 (1998-2003, 22 cases) and P-2 (2004-2008, 45 cases), which have been compared to evaluate the evolution of the LA technique.

RESULTS

Indications for LA were: 19 incidentalomas, 19 primary hyperaldosteronism, 18 pheocromocitoms, 5 cases of symptomatic and non-functioning adrenal masses, 4 Cushing adenomas and 2 metastases. There was no mortality, only 4 patients had minor complications (6%) and conversion rate was only 3% (2 cases). Mean size of adrenal glands resected was 3.83 cm and the mean operative time was 86 minutes. Mean postoperative hospital stay was 3 days and in P-2 seventeen patients were discharged on an outpatient basis (hospital stay less than 23 hours).

CONCLUSIONS

In our experience, LA for the treatment of adrenal diseases has shown to be safe, effective and reproducible with low complications and excellent tolerance by patients. When the learning curve is overcome, hospital stay and operative time clearly decrease. As a consequence, LA can be planned in selected cases as outpatient surgery with good results.
