Impact of prophylactic central lymph node dissection on the complications and recurrence rates in papillary thyroid carcinoma-An AFCE (French-speaking Association of Endocrine Surgery) multicentre study based on the EUROCRINE® national data.

BACKGROUND: Prophylactic central neck dissection (pCND) remains controversial during the initial surgery for preoperative and intraoperative node-negative (cN0) papillary thyroid carcinoma (PTC). METHODS: Patients undergoing thyroidectomy with or without pCND (Nx) for PTC in nine French surgical departments, registered in the EUROCRINE® national data in France between January 2015 and June 2021, were included in a cohort study. Demographic and clinicopathological characteristics, complications, and recurrence rates were compared using multivariate regression analysis. RESULTS: A total of 1905 patients with cN0 PTC were enrolled, including 1534 who had undergone pCND and 371 who hadn't (Nx). Of these, 1546 (81.2%) were female, and the median age was 49 years (range: 15-89 years). Patients who had undergone pCND were more likely to have multifocal tumors (n = 524 [34.2%] vs. n = 68 [18.3%], p < .001) and larger tumors (15.3 vs. 10.2 mm, p = .01) than patients with Nx. Of the patients with pCND, 553 (36%) had positive central LN (N1a), with a median of 1 N1 (IQR 0-5). pCND was associated with a higher temporary hypocalcemia rate (n = 25 [8%] vs. n = 15 [4%], p < .001). The rates of permanent hypocalcemia and temporary and permanent recurrent laryngeal nerve (RLN) palsy were not significantly different between the two groups (p > .2). After adjusting for covariates (age, sex, multifocality, and pathological T stage) in a multivariable Cox PH model, the performance of lymph node dissection (pCND vs. no-pCND) was not associated with PTC recurrence (p = .2). CONCLUSION: pCND in PTC does not reduce recurrence and is associated with a two-fold increase in the incidence of transient hypoparathyroidism. These data should be considered while issuing further guidelines regarding the treatment of patients with cN0 PTC.

Preoperative Follow-up in Bariatric Surgery: Why They Give Up? Rate, Causes, and Economic Impact of Dropout.

BACKGROUND: Preoperative attrition is highly prevalent in patients referred for bariatric surgery. Little information is available neither on reasons reported by patients for attrition in knowledge nor costs of attrition in a publicly funded health system. OBJECTIVES: To assess the reasons for the attrition of bariatric candidates and calculate its economic impact on a population with obesity in a public hospital in France. METHODS: This is a retrospective study including all bariatric surgery candidates between 2014 and 2018 in our Center of Excellence in Obesity Care. Data were extracted from the hospital information system, and patient-related outcomes were collected via a standardized questionnaire. Economic analysis was performed. Primary outcome was to analyze the rate of preoperative attrition. Secondary outcome was reasons for discontinuation and their economic impact. RESULTS: In total, 1360 patients were referred for bariatric surgery at our hospital, and 1225 were included in the study. Attrition rate in preoperative phase was 46.8%. Three factors were significantly associated with follow-up fragmentation risk: unemployment (OR 0.52, 95% CI 0.29-0.7, p < 0.001), active smoking (OR 2.24, 95% CI 1.53-5.15, p < 0.001), and body mass index (OR 0.98, 95% CI 0.97-1.00, p = 0.036). Average cost to the healthcare system was €792 for each patient who dropped out. CONCLUSIONS: We identified predictors and patient-reported factors that seem to be beyond the possibility of removal by health professionals. We should consider and address preventable factors, through the development of care pathways tailored to the individual profile of a patient.

Colorectal intussusception due to adenocarcinoma presenting as acute bowel obstruction in an adult.

Colorectal intussusception is a rare entity in adults presenting an acute abdomen. The authors present a case of a 73-year-old female who presented with an acute large bowel obstruction. Abdominal computed tomography (CT) scan reveals a colorectal intussusception with a colonic distension upstream. Laparoscopy founds out a stenotic tumor on colorectal junction corresponding with an adenocarcinoma on histopathological exam. CT scan is the most specific diagnostic test for intussusception and is superior to ultrasonography and endoscopy and thus should be performed preferentially.

Long-Term Outcome Following Implanted Pulse Generator Change in Patients Treated With Sacral Nerve Modulation for Fecal Incontinence.

BACKGROUND: Long-term outcome of sacral nerve modulation (SNM) patients after implanted pulse generator (IPG) change for fecal incontinence (FI) is unknown. This study reported the outcome and long-term satisfaction after a change of an exhausted IPG, questioning the need to concurrently change the electrode and looking for factors involved in the maintenance of treatment efficiency. METHODS: Patients with fecal incontinence and with a Medtronic IPG implanted in a single center (2001-2016) were prospectively followed up. Satisfaction was graded according to a patient-reported outcome measure from 0 to 10. A pre- and postreplacement FI severity score (Cleveland Clinic Fecal Incontinence Score) and Fecal Incontinence Quality of Life questionnaire were also collected. RESULTS: In 170 patients with SNM, 39 had an IPG replacement. At a median of 29 month after replacement, 32 and 7 patients reported respectively a similar and reduced satisfaction (7.6 ± 1.62 vs. 5.5 ± 0.87), p < .001. Satisfied patients were younger (65 years vs. 76 years, p < .001). Cleveland Clinic Fecal Incontinence Scores were not significantly different, but the satisfied group had a significantly better Fecal Incontinence Quality of Life score (p = .047). Only 5 patients needed an electrode change at the time of the IPG replacement or later. CONCLUSIONS: Patient satisfaction and efficiency remain high after IPG replacement. Older age has a negative impact on the outcome. Electrode replacement is rarely required and does not need to be performed routinely when an IPG is exhausted. CONFLICT OF INTEREST: Paul-Antoine Lehur has a consulting agreement with Medtronic SA. This had no impact with the results of the study. The other authors have no conflict of interests to declare.
