- OBJECTIVE: To investigate the prevalence and risk factors for permanent hypoparathyroidism after total thyroidectomy for benign disease in a population-based setting with data independent of input of complication data.SUMMARY OF BACKGROUND DATA: The reported rate of permanent hypoparathyroidism is highly variable and mostly rely on reported complication data from national or institutional registries.METHODS: All patients who underwent total thyroidectomy in Sweden from 2005 to 2015 were identified through Scandinavian Quality Register for Thyroid, Parathyroid and Adrenal Surgery and the Swedish National Patient Register. Patients were matched to outcome data from the Swedish Prescribed Drug Register. Permanent hypoparathyroidism was defined as treatment with calcium and/or active vitamin D more than 1 year after surgery.RESULTS: Seven thousand eight hundred fifty-two patients were included and 938 (12.5%) developed permanent hypoparathyroidism. The risk was lower in patients registered in the quality register (11.0% vs 16%, P < 0.001). In a multivariable analysis there was a higher risk of permanent hypoparathyroidism in patients with parathyroid autotransplantation [Odds ratio (OR) 1.72; 95% confidence interval 1.47-2.01], center-volume <100 thyroidectomies per year (OR 1.22; 1.03-1.44), age above 60 year (OR 1.64; 1.36-1.98) and female sex (OR 1.27; 1.05-1.54). Reported data from the quality register only identified 178 of all 938 patients with permanent hypoparathyroidism.CONCLUSION: The risk of permanent hypoparathyroidism after total thyroidectomy was high and associated with parathyroid autotransplantation, higher age, female sex and surgery at a low volume center. Reported follow-up data might underestimate the rate of permanent hypoparathyroidism.

- BACKGROUND/OBJECTIVE:: This study attempted a national inventory of all bilateral prophylactic mastectomies performed in Sweden between 1995 and 2005 in high-risk women without a previous breast malignancy. The primary aim was to investigate the breast cancer incidence after surgery. Secondary aims were to describe the preoperative risk assessment, operation techniques, complications, histopathological findings, and regional differences. METHODS:: Geneticists, oncologists and surgeons performing prophylactic breast surgery were asked to identify all women eligible for inclusion in their region. The medical records were reviewed in each region and the data were analyzed centrally. The BOADICEA risk assessment model was used to calculate the number of expected/prevented breast cancers during the follow-up period. RESULTS:: A total of 223 women operated on in 8 hospitals were identified. During a mean follow-up of 6.6 years, no primary breast cancer was observed compared with 12 expected cases. However, 1 woman succumbed 9 years post mastectomy to widespread adenocarcinoma of uncertain origin. Median age at operation was 40 years. A total of 58% were BRCA1/2 mutation carriers. All but 3 women underwent breast reconstruction, 208 with implants and 12 with autologous tissue. Four small, unifocal, invasive cancers and 4 ductal carcinoma in situ were found in the mastectomy specimens. The incidence of nonbreast related complications was low (3%). Implant loss due to infection/necrosis occurred in 21 women (10%) but a majority received a new implant later. In total, 64% of the women underwent at least 1unanticipated secondary operation. CONCLUSIONS:: Bilateral prophylactic mastectomy is safe and efficacious in reducing future breast cancer in asymptomatic women at high risk. Unanticipated reoperations are common. Given the small number of patients centralization seems justified.

- Background: Sentinel lymph node biopsy is an established staging method in early breast cancer. After a negative biopsy, most institutions will not perform a completion axillary dissection. The present study reports the current axillary recurrence (AR) rate, overall and disease-free survival in the Swedish Multicenter Cohort Study.Methods: From 3534 patients with primary breast cancer ≤3 cm prospectively enrolled in the Swedish multicenter cohort study, 2246 with a negative sentinel node biopsy and no further axillary surgery were selected. Follow-up consisted of annual clinical examination and mammography. Twenty-six hospitals and 131 surgeons contributed to patient accrual.Results: After a median follow-up time of 37 months (0-75), the axilla was the sole initial site of recurrence in 13 patients (13 of 2246, 0.6%). In another 7 patients, axillary relapse occurred after or concurrently with a local recurrence in the breast, and in a further 7 cases, it coincided with distant or extra-axillary lymphatic metastases. Thus, a total of 27 ARs were identified (27 of 2246, 1.2%). The overall 5-year survival was 91.6% and disease-free survival 92.1%.Conclusions: This is the first report from a national multicenter study that covers, not only highly specialized institutions but also small community hospitals with just a few procedures per year. Despite this heterogeneous background, the results lie well within the range of AR rates published internationally (0%-3.6%). The sentinel node biopsy procedure seems to be safe in a multicenter setting. Nevertheless, long-term follow-up data should be awaited before firm conclusions are drawn.

- OBJECTIVE: To analyze tumor biology and the outcome of differentiated treatment in relation to tumor subtype in patients with gastric carcinoid. BACKGROUND: Gastric carcinoids may be subdivided into ECL cell carcinoids (type 1 associated with atrophic gastritis, type 2 associated with gastrinoma, type 3 without predisposing conditions) and miscellaneous types (type 4). The biologic behavior and prognosis vary considerably in relation to type. METHODS: A total of 65 patients from 24 hospitals (51 type 1, 1 type 2, 4 type 3, and 9 type 4) were included. Management recommendations were issued for newly diagnosed cases, that is, endoscopic or surgical treatment of type 1 and 2 carcinoids (including antrectomy to abolish hypergastrinemia) and radical resection for type 3 and 4 carcinoids. RESULTS: Infiltration beyond the submucosa occurred in 9 of 51 type 1, 4 of 4 type 3, and 7 of 9 type 4 carcinoids. Metastases occurred in 4 of 51 type 1 (3 regional lymph nodes, 1 liver), the single type 2 (regional lymph nodes), 3 of 4 type 3 (all liver), and 7 of 9 type 4 carcinoids (all liver). Of the patients with type 1 carcinoid, 3 had no specific treatment, 40 were treated with endoscopic or surgical excision (in 10 cases combined with antrectomy), 7 underwent total gastrectomy, and 1 underwent proximal gastric resection. Radical tumor removal was not possible in 2 of 4 patients with type 3 and 7 of 9 patients with type 4 carcinoid. Five- and 10-year crude survival rates were 96.1% and 73.9% for type 1 (not different from the general population), but only 33.3% and 22.2% for type 4 carcinoids. CONCLUSION: Subtyping of gastric carcinoids is helpful in the prediction of malignant potential and long-term survival and is a guide to management. Long-term survival did not differ from that of the general population regarding type 1 carcinoids but was poor regarding type 4 carcinoids.

- Objective:To report the mid-term outcomes of fenestrated-branched endovascular aneurysm repair (F-BEVAR) following a failed previous endovascular aneurysm repair (pEVAR) or previous open aneurysm repair (pOAR).Methods:Data from consecutive patients who underwent F-BEVAR for pEVAR or pOAR from 2006 to 2021 from 17 European vascular centers were analyzed. Endpoints included technical success, major adverse events, 30-day mortality, and 5-year estimates of survival, target vessel primary patency, freedom from reinterventions, type I/III endoleaks, and sac growth >5 mm.Background:Treatment of a failed previous abdominal aortic aneurysm repair is a complex undertaking. F-BEVAR is becoming an increasingly attractive option, although comparative data are limited regarding associated risk factors, indications for treatment, and various outcomes.Results:There were 526 patients included, 268 pOAR and 258 pEVAR. The median time from previous repair to F-BEVAR was 7 (interquartile range, 4-12) years, 5 (3-8) for pEVAR, and 10 (6-14) for pOAR, P<0.001. Predominant indication for treatment was type Ia endoleak for pEVAR and progression of the disease for pOAR. Technical success was 92.8%, pOAR (92.2%), and pEVAR (93.4%), P=0.58. The 30-day mortality was 6.5% overall, 6.7% for pOAR, and 6.2% for pEVAR, P=0.81. There were 1853 treated target vessels with 5-year estimates of primary patency of 94.4%, pEVAR (95.2%), and pOAR (94.4%), P=0.03. Five-year estimates for freedom from type I/III endoleaks were similar between groups; freedom from reintervention was lower for pEVAR (38.3%) than for pOAR (56.0%), P=0.004. The most common indication for reinterventions was for type I/III endoleaks (37.5%).Conclusions:Repair of a failed pEVAR or pOARis safe and feasible with comparable technical success and survival rates. While successful treatment can be achieved, significant rates of reintervention should be anticipated, particularly for issues related to instability of target vessels/bridging stents.

- Objective: To describe outcomes after elective and non-elective fenestrated-branched endovascular aortic repair (FB-EVAR) for thoracoabdominal aortic aneurysms (TAAAs).Background: FB-EVAR has been increasingly utilized to treat TAAAs; however, outcomes after non-elective versus elective repair are not well described.Methods: Clinical data of consecutive patients undergoing FB-EVAR for TAAAs at 24 centers (2006-2021) were reviewed. Endpoints including early mortality and major adverse events (MAEs), all-cause mortality, and aortic-related mortality (ARM), were analyzed and compared in patients who had non-elective versus elective repair.Results: A total of 2603 patients (69% males; mean age 72 +/- 10 year old) underwent FB-EVAR for TAAAs. Elective repair was performed in 2187 patients (84%) and non-elective repair in 416 patients [16%; 268 (64%) symptomatic, 148 (36%) ruptured]. Non-elective FB-EVAR was associated with higher early mortality (17% vs 5%, P < 0.001) and rates of MAEs (34% vs 20%, P < 0.001). Median follow-up was 15 months ( interquartile range, 7-37 months). Survival and cumulative incidence of ARM at 3 years were both lower for non-elective versus elective patients (50 +/- 4% vs 70 +/- 1% and 21 +/- 3% vs 7 +/- 1%, P < 0.001). On multivariable analysis, non-elective repair was associated with increased risk of all-cause mortality ( hazard ratio, 1.92; 95% CI] 1.50-2.44; P < 0.001) and ARM (hazard ratio, 2.43; 95% CI, 1.63-3.62; P < 0.001).Conclusions: Non-elective FB-EVAR of symptomatic or ruptured TAAAs is feasible, but carries higher incidence of early MAEs and increased all-cause mortality and ARM than elective repair. Long-term follow-up is warranted to justify the treatment.

- Objective: To compare the efficacy and safety of early, nasogastric enteral nutrition (EN) with total parenteral nutrition (TPN) in patients with predicted severe acute pancreatitis (SAP). Summary Background Data: In SAP, the magnitude of the inflammatory response as well as increased intestinal permeability correlates with outcome. Enteral feeding has been suggested superior to parenteral feeding due to a proposed beneficial effect on the gut barrier. Methods: Fifty patients who met the inclusion criteria were randomized to TPN or EN groups. The nutritional regimen was started within 24 hours from admission and EN was provided through a nasogastric tube. The observation period was 10 days. Intestinal permeability was measured by excretion of polyethylene glycol (PEG) and concentrations of antiendotoxin core antibodies (Endocab). Interieukins (IL)-6 IL-8, and C-reactive protein (CRP) were used as markers of the systemic inflammatory response. Morbidity and feasibility of the nutritional route were evaluated by the frequency of complications, gastrointestinal symptoms, and abdominal pain. Results: PEG, Endocab, CRP, IL-6, APACHE II score, severity according to the Atlanta classification (22 patients), and gastrointestinal symptoms or abdominal pain did not significantly differ between the groups. The incidence of hyperglycemia was significantly higher in TPN patients (21 of 26 vs. 7 of 23; P < 0.001). Total complications (25 vs. 52; P = 0.04) and pulmonary complications (10 vs. 21; P = 0.04) were significantly more frequent in EN patients, although complications were diagnosed dominantly within the first 3 days. Conclusion: In predicted SAP, nasogastric early EN was feasible and resulted in better control of blood glucose levels, although the overall early complication rate was higher in the EN group. No beneficial effects on intestinal permeability or the inflammatory response were seen by EN treatment.
