Hemithyroidectomy versus total thyroidectomy in the intermediate-risk differentiated thyroid cancer: the Italian Societies of Endocrine Surgeons and Surgical Oncology Multicentric Study.

The surgical treatment of the intermediate-risk DTC (1-4 cm) remains still controversial. We analyzed the current practice in Italy regarding the surgical management of intermediate-risk unilateral DTC to evaluate risk factors for recurrence and to identify a group of patients to whom propose a total thyroidectomy (TT) vs. hemithyroidectomy (HT). Among 1896 patients operated for thyroid cancer between January 2017 and December 2019, we evaluated 564 (29.7%) patients with unilateral intermediate-risk DTC (1-4 cm) without contralateral nodular lesions on the preoperative exams, chronic autoimmune thyroiditis, familiarity or radiance exposure. Data were collected retrospectively from the clinical register from 16 referral centers. The patients were followed for at least 14 months (median time 29.21 months). In our cohort 499 patients (88.4%) underwent total thyroidectomy whereas 65 patients (11.6%) underwent hemithyroidectomy. 151 (26.8%) patients had a multifocal DTC of whom 57 (10.1%) were bilateral. 21/66 (32.3%) patients were reoperated within 2 months from the first intervention (completion thyroidectomy). Three patients (3/564) developed regional lymph node recurrence 2 years after surgery and required a lymph nodal neck dissection. The single factor related to the risk of reoperation was the histological diameter (HR = 1.05 (1.00-1-09), p = 0.026). Risk stratification is the key to differentiating treatment options and achieving better outcomes. According to the present study, tumor diameter is a strong predictive risk factor to proper choose initial surgical management for intermediate-risk DTC.

Robot-assisted laparoscopic gastrectomy with D2 dissection for adenocarcinoma: initial experience with 17 patients.

Robot-assisted gastrectomy has been practised so far in very few centres in the world. The aims of this study were to assess the feasibility of robot-assisted gastrectomy for adenocarcinoma with D2 lymph nodal dissection and to analyze our preliminary results. Between January 2006 and August 2008, as many as 17 patients (11 females, 6 males) underwent laparoscopic robot-assisted surgery for non-metastatic adenocarcinoma of the stomach by a 3-armed da Vinci(®) Robotic Surgical System. The mean age of patients was 65.9 years. This series included eight patients with early gastric cancer (EGC) and nine with advanced gastric cancer (AGC). A 4/5 laparoscopic subtotal gastrectomy (LSG) with D2 nodal clearance was the procedure of choice for 16 distal cancers. Laparoscopic total gastrectomy (LTG) with D2 lymphadenectomy was performed for one AGC of the middle third of the stomach. No intraoperative complication was registered. Conversion to laparotomy was required in two patients with distal cancer. The mean operating time (excluding converted patients) was 352 min (348 for LSG). Morbidity consisted in one pancreatic leak that healed conservatively. One death occurred postoperatively for haemorragic stroke. On average, 25.5 ± 4 lymph nodes were collected (range 10-40). The resection margin was 6.4 ± 0.6 cm (range 4.2-8), and the margin was tumour free in all the specimens. The mean hospital stay of totally laparoscopic subtotal gastrectomy was 10 ± 1.2 days (range 8-13). The mean follow-up was 14 months (range 1-29) and three patients with AGC showed recurrence after LSG and died of disease. Robotics in gastrectomy for cancer is a feasible and safe procedure, yielding adequate D2 nodal clearance with respect of oncologic principles. Robotic techniques can represent a remarkable tool to improve laparoscopic surgeon's ability and precision in small surgical fields, i.e. during D2 dissection. This study demonstrated the feasibility of robot-assisted gastrectomy for cancer although further studies are required to validate our preliminary results, especially as far as patients' benefits are concerned.

[Bleeding in diverticular disease of the colon]. / Il sanguinamento nella malattia diverticolare del colon.

The incidence of bleeding from diverticular disease ranges from 3 to 30%. Haemorrhage is more common when the whole colon is affected; the source is more frequently in the right colon. Typically, the bleeding is massive, with 15% of the patients admitted in shock. It nearly always stops spontaneously, but recurrence rate is high. Chronic blood loss suggests alternative sources. Emergency angiography detects aetiology and site of the haemorrhage in most of the patients. Vasopressin infusion can frequently stop the bleeding. Colonoscopy is profitable only when bleeding stops, after a rapid clearing of the colon. On the other hand, intraoperative colonoscopy could be useful in emergency cases when urgent surgery is clearly indicated. Surgical treatment is requested only in few patients: segmental resections (generally right hemicolectomy) are indicated when there is evidence of the source of the blood loss. In the other cases sub-total or total colectomy are justified and provide better and safer results.
