When symptoms do manifest, they are associated with dysfunction of the parathyroid glands. Surgical treatment is considered the first choice and the only curative treatment for pHPT, offering advantages for both symptomatic and asymptomatic patients. The aim of this study is to report our experience in the management of 6 selected complex cases, which often require a multidisciplinary approach due to the lack of established diagnostic and therapeutic algorithms and the variability of clinical presentation and atypical parathyroid adenoma location. We present a series of cases examining the various treatment approaches in six distinct patients: one patient with parathyroid carcinoma with concomitant parathyroid adenoma, a case involving mediastinal parathyroidectomy, a case with an intrathymic parathyroid adenoma, two cases of recurrent pHPT, and one case of hereditary pHPT in Multiple Endocrine Neoplasia (MEN) 1 syndrome.

The risk of bias was evaluated with the Newcastle-Ottawa scale.</p><p><strong>Results: </strong>Six studies were included in our analysis for a total of 652 patients (316 robotic and 336 laparoscopic). The R-LLND group had a longer operative time (WMD 60.46, <i>p</i> = 0.02) and less blood loss (WMD -22.33, <i>p</i> = 0.01). Differences were found in the postoperative length of stays (7 days ± 1.2 and 14 ± 5.2 versus 7 days ± 0.3 and 16 ± 18.5, WMD -1.30, <i>p</i> = 0.03) and in the mean time to regular diet (3 days ± 0.5 and 5 ± 2.3 versus 3 days ± 1.2 and 6 ± 3.8, WMD -0.60 <i>p</i> = 0.01); a slightly higher number of harvested lateral lymph nodes was present in the L-LLND group (WMD 1.23, <i>p</i> = 0.02).</p><p><strong>Conclusions: </strong>Our work demonstrates a slight benefit from the robotic approach when performing LLND in terms of intra- and peri-operative outcomes, despite not reaching statistical significance a trend in favor of robotic surgery is evident in almost all the analyzed topic.</p>","PeriodicalId":8210,"journal":{"name":"Annali italiani di chirurgia","volume":"96 7","pages":"847-858"},"PeriodicalIF":0.9,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
