Introduction: The versatile open modular design of the newly introduced robotic platform Hugo^TM RAS is expected to allow its rapid spread in general surgery. However, the system is not yet approved for use in oesophageal and HPB-surgery and is not licensed worldwide. The aim of this work was to review the current spectrum of general surgical procedures that may be feasibly and safely performed with Hugo. Methods: We retrospectively reviewed our own series and performed a systematic review of all the published reports of general surgical procedures performed with this system in the literature. Results: Seventy patients underwent general surgery with Hugo at our institution, and another 99 patients were reported in the literature. The most common procedures were colorectal (n = 55); cholecystectomy (n = 44); repair of groin, ventral and hiatal hernias (n = 34); upper GI (n = 28); adrenalectomy (n = 6); and spleen cyst deroofing (n = 2). No device-related complications were reported. Arm collisions and technical problems were rare. The docking and console times improved in all series. The port positions and robotic arm configurations varied among authors and depended on the surgical indication, patient characteristics and surgeon’s preference. Conclusions: A wide spectrum of general surgical procedures has been safely and effectively performed with the Hugo RAS, even by robotically inexperienced teams with a limited choice of instruments. Technical improvements to the system and the introduction of robotic energy devices may help Hugo evolve to a vital alternative to established robotic systems. Full article

Background: While the current guidelines recommend laparoscopic deroofing for symptomatic simple liver cysts, percutaneous drainage may serve as a less invasive alternative method. In this study, the treatment effects of percutaneous drainage with or without sclerotherapy for symptomatic simple liver cysts were evaluated. Methods: Between April 2016 and March 2021, 79 patients who initially required hospitalization due to symptomatic simple liver cysts were enrolled in this multicenter retrospective study. They were treated percutaneously with or without sclerotherapy. The factors associated with symptom recurrence, clinical course and prognosis were investigated. Results: Of the 79 patients treated percutaneously, 11 (13.9%) had symptom recurrence due to liver cysts during the observation period. The maximum diameter of liver cysts at baseline was the only significant factor for the recurrence of these symptoms (p = 0.004). In a receiver operating characteristics analysis, the cut-off of the diameter for symptom recurrence was 16.5 cm. No additional effect of sclerotherapy on drainage was demonstrated in patients with a cyst diameter of <16.5 cm, and in patients with a cyst diameter of ≥16.5 cm, the cumulative recurrence rates of symptoms were significantly lower in the patients treated via sclerotherapy with 5% ethanolamine oleate or with minocycline hydrochloride than in those treated with drainage alone or via sclerotherapy with absolute ethanol. No problematic adverse effects were observed of sclerotherapy. Conclusions: Drainage with sclerotherapy with 5% ethanolamine oleate or minocycline hydrochloride was an effective and safe treatment for patients whose liver cysts had a maximum diameter of ≥16.5 cm. Considering both its efficacy and safety, sclerotherapy with either of these agents is recommended for patients with a maximum liver cyst diameter of ≥16.5 cm. Full article

Simulation training for invasive dental procedures is a core component of the pre-clinical dental curriculum. Besides conventional mannequin-based simulators, dental schools are now incorporating haptic virtual reality simulation (HVRS) devices to facilitate the transition of students from the simulated dental learning environment to the clinical settings. This study aimed to assess student performance and perceptions of HVRS training as a pedagogical tool in pre-clinical paediatric dentistry. After practicing the primary molar pulpotomy procedure on plastic teeth, participants were randomized into test and control groups. Test group students performed the same procedure on a HVRS device, namely the SIMtoCARE Dente^®. Subsequently, both the test and control group students attended another conventional pulpotomy simulation session where the quality of their access outline and pulp chamber deroofing steps were evaluated on plastic teeth. After the control group students also experienced the HVRS, all study participants completed a perception questionnaire on their experience. No significant differences were found between the study and control group students for the quantitative parameters assessed. Although the students regarded HVRS to be a useful adjunct to support their pre-clinical training, an overwhelming majority of the students did not consider HVRS to be a replacement for conventional pre-clinical simulation training.

Background: Symptomatic parapelvic cysts (PPC) are rare entities. Our objective is to highlight specific features of PPC to avoid a misdiagnosis of UPJ obstruction. Methods: We retrospectively reviewed the records of children managed between 2012–2017. Results: All four patients (18 months–8 years) presented with acute renal colic with a large intra-sinusal liquid mass (42–85 mm) on ultrasound, evoking a diagnosis of UPJ obstruction. On preoperative renal scintigraphy (n = 3) there was no dilatation of the renal pelvis and ipsilateral differential function was impaired in 2. Diagnosis of PPC was suspected preoperatively in three children (CT scan (n = 1); MRI (n = 2)) and made peri-operatively (n = 1). Preoperative retrograde pyelography (n = 3) and a further intraoperative retrograde pyelography with methylene blue (n = 1) did not identify communication with the cyst. No renal pelvis was identified in two patients. De-roofing of the cyst was curative in all cases at 5 years mean follow-up (no leakage, cyst recurrence or loss of function) and all 4 patients became asymptomatic after surgery. Histology demonstrated a single flat epithelial cell layer. Renal function normalized in one patient but remained impaired in the other. Conclusion: In case of symptoms of UPJ obstruction with a medial renal liquid mass on ultrasound, PPC should be considered when no dilatated pelvis on renal scan is identified. In such cases, a complementary imaging work-up is mandatory prior to surgery. Full article

(1) Background: Several techniques for the treatment of pilonidal sinus disease (PSD) are in vogue, though none have emerged as the gold standard. Laying open (deroofing) and curettage under local anesthesia is one of the most straightforward procedures to treat PSD. In this study, the long-term follow-up in a large series was analyzed. (2) Methods: The laying open approach was performed for all types of consecutive PSD patients—simple, complicated, and abscess. The primary outcome parameter of the study was the healing rate. The secondary outcome parameters were operating time, hospital stay, time to resumption of normal work, and healing time. (3) Results: 111 (M/F–92/19, mean age-22.9 ± 5.7 years) consecutive patients were operated on and followed for 38 months (6–111 months). Of these, 24 had pilonidal abscesses, 87 had chronic pilonidal disease, while 22 had recurrent disease. Operating time and hospital stay were 24 ± 7 min and 66 ± 23 min, respectively. On average, patients could resume normal work in 3.6 ± 2.9 days and the healing time was 43.8 ± 7.4 days. Three patients were lost to follow-up. Complete resolution of the disease occurred in 104/108 (96.3%) patients, while 4 (3.7%) had a recurrence. One recurrence was due to a missed tract, while three recurrences presented after complete healing had occurred. Two patients with recurrence were operated on again with the same procedure, and both healed completely. Thus, the overall success rate of this procedure was 98.1% (106/108) with a recurrence rate after first surgery of 3.7% over a median follow-up of 38 months. (4) Conclusions: Pilonidal disease managed by laying open (deroofing) with curettage under local anesthesia is associated with a high cure rate. This procedure is effective in treating all kinds of pilonidal disease (simple, complicated, and abscess). Full article

There is an increasing consensus that the treatment of Hidradenitis suppurativa (HS) significantly varies with the degree of inflammation and that treatment according to guidelines is not always successful. Here, we report the case of a 31-year-old male with widespread, highly inflammatory Hurley Stage II HS in multiple locations who failed to respond to any kind of established medical treatment, including biologics. As an alternative approach, Ustekinumab was maintained, and additionally the patient was treated with LAight therapy, a combination of intense pulsed light and radiofrequency. After 10 sessions, deroofing of multiple lesions was performed in a two-step process. After a few weeks of healing time accompanied by specialized wound experts, the patient continued with LAight therapy to control and prevent recurrence. This case shows that the combination of LAight therapy and deroofing is a promising treatment plan for the long-term symptom control of mild and moderate HS. Full article
