Introduction of laparoscopic nephrectomy for autosomal dominant polycystic kidney disease as the standard procedure.

PURPOSE: Autosomal dominant polycystic kidney disease (ADPKD) is a common hereditary disorder and accounts for 5-10% of all cases of kidney failure. 50% of ADPKD patients reach kidney failure by the age of 58 years requiring dialysis or transplantation. Nephrectomy is performed in up to 20% of patients due to compressive symptoms, renal-related complications or in preparation for kidney transplantation. However, due to the large kidney size in ADPKD, nephrectomy can come with a considerable burden. Here we evaluate our institution's experience of laparoscopic nephrectomy (LN) as an alternative to open nephrectomy (ON) for ADPKD patients. MATERIALS AND METHODS: We report the results of the first 12 consecutive LN for ADPKD from August 2020 to August 2021 in our institution. These results were compared with the 12 most recent performed ON for ADPKD at the same institution (09/2017 to 07/2020). Intra- and postoperative parameters were collected and analyzed. Health related quality of life (HRQoL) was assessed using the SF36 questionnaire. RESULTS: Age, sex, and median preoperative kidney volumes were not significantly different between the two analyzed groups. Intraoperative estimated blood loss was significantly less in the laparoscopic group (33 ml (0-200 ml)) in comparison to the open group (186 ml (0-800 ml)) and postoperative need for blood transfusion was significantly reduced in the laparoscopic group (p = 0.0462). Operative time was significantly longer if LN was performed (158 min (85-227 min)) compared to the open procedure (107 min (56-174 min)) (p = 0.0079). In both groups one postoperative complication Clavien Dindo ≥ 3 occurred with the need of revision surgery. SF36 HRQol questionnaire revealed excellent postoperative quality of life after LN. CONCLUSION: LN in ADPKD patients is a safe and effective operative procedure independent of kidney size with excellent postoperative outcomes and benefits of minimally invasive surgery. Compared with the open procedure patients profit from significantly less need for transfusion with comparable postoperative complication rates. However significant longer operation times need to be taken in account.

Early and midterm results of radiofrequency ablation (Rafaelo® procedure) for third-degree haemorrhoids: a prospective, two-centre study.

BACKGROUND: The aim of this study was to evaluate the safety and efficacy of radiofrequency ablation (RFA) for treating third degree haemorrhoids, with a follow-up over 2 years. METHODS: We conducted a prospective, two-centre study to assess RFA of third-degree haemorrhoids in an outpatient setting. Treatment was performed under local anaesthesia, optionally in combination with sedation. The primary endpoint was analysis of a proctological symptom score ([PSS] bleeding, itching, pain, soiling) and proctological examination to detect recurrence at 1, 6, 12 and 24 months after surgery. The secondary endpoints were postoperative complications, incidence of postoperative pain, including administration of analgesics and time to return to daily routine. RESULTS: Ninety-eight patients were included in the study. The mean age of the patients was 49.1 ± 10.9 (mean ± SD). 83 patients (84.7%) were male and 15 patients (15.3%) were female. The follow-up involved 100% (1 month), 95% (6 months), 86% (12 months) and 74% after 24 months. The individual symptom scores and overall PSS score decreased significantly in comparison to the initial score at each time point assessed. Prolapsed haemorrhoids decreased in comparison to the initial situation (100%) to 7.2% (1 month), 3.5% (6 months), 13.1% (12 months) and 13.7% (after 24 months). Thirteen patients (12.7%) required repeat haemorrhoid therapy during the 2-year follow-up period. The mean maximum pain score after the procedure was 2.5 ± 2.7 (determined with the visual analogue scale), while 33 (33.7%) patients reported having no pain. 59 (60.2%) patients did not take analgesics after the procedure. Eleven patients (11.2%) experienced minor complications (bleeding, fever, cramps, diarrhoea, anal venous thrombosis) but did not require additional treatment. Eight cases (8.2%) of major complications (infection, bleeding, severe pain) required treatment with antibiotics, a second intervention, analgesics or hospitalization. CONCLUSIONS: RFA is safe and effective for treatment of third-degree haemorrhoids. The main advantages of this new method are its use on an outpatient basis under local anaesthesia, a very low level of postoperative pain and significant control of haemorrhoid symptoms over 2 years.
