Risk factors for postoperative cervical haematoma in patients undergoing thyroidectomy: a retrospective, multicenter, international analysis (REDHOT study).

Background: Postoperative cervical haematoma represents an infrequent but potentially life-threatening complication of thyroidectomy. Since this complication is uncommon, the assessment of risk factors associated with its development is challenging. The main aim of this study was to identify the risk factors for its occurrence. Methods: Patients undergoing thyroidectomy in seven high-volume thyroid surgery centers in Europe, between January 2020 and December 2022, were retrospectively analysed. Based on the onset of cervical haematoma, two groups were identified: Cervical Haematoma (CH) Group and No Cervical Haematoma (NoCH) Group. Univariate analysis was performed to compare these two groups. Moreover, employing multivariate analysis, all potential independent risk factors for the development of this complication were assessed. Results: Eight thousand eight hundred and thirty-nine patients were enrolled: 8,561 were included in NoCH Group and 278 in CH Group. Surgical revision of haemostasis was performed in 70 (25.18%) patients. The overall incidence of postoperative cervical haematoma was 3.15% (0.79% for cervical haematomas requiring surgical revision of haemostasis, and 2.35% for those managed conservatively). The timing of onset of cervical haematomas requiring surgical revision of haemostasis was within six hours after the end of the operation in 52 (74.28%) patients. Readmission was necessary in 3 (1.08%) cases. At multivariate analysis, male sex (P < 0.001), older age (P < 0.001), higher BMI (P = 0.021), unilateral lateral neck dissection (P < 0.001), drain placement (P = 0.007), and shorter operative times (P < 0.001) were found to be independent risk factors for cervical haematoma. Conclusions: Based on our findings, we believe that patients with the identified risk factors should be closely monitored in the postoperative period, particularly during the first six hours after the operation, and excluded from outpatient surgery.

Binaural beats reduce feeling of pain and discomfort during colonoscopy procedure in not-sedated patients: A randomized control trial.

BACKGROUND AND PURPOSE: This study aimed to determine the effect of Binaural Beats(BB)on feeling of pain, and patient comfort during colonoscopy without sedation. MATERIALS AND METHODS: It is a randomized, controlled, double-blind procedural study of 115 patients that underwent colonoscopy without sedation. The patients were randomly assigned into the experimental group (n = 42) and the control group (n = 48) that were given BB starting 5 min before and continuing until the end of the colonoscopy procedure without any intervention other than routine nursing care. Measures of the state of anxiety (VAS-Anxiety scale) administered before the procedure, and measures of feeling of pain (Visual Analogue scale VAS-pain), Satisfactory and Willingness to repeat the procedure as Likert scales were also collected soon after the colonoscopy procedure. RESULTS: Feeling of pain was lower and scores of the level of comfort were higher in the experimental group when compared to the control group (p < 0.05). CONCLUSIONS: BB is an effective and safe method for reducing pain and improving patient comfort in cases undergoing colonoscopy without sedation. Since BB method is a non-pharmacological, non-invasive, inexpensive and simple method without any side effects, it may be used to reduce the feeling of pain and discomfort for non-sedated patients undergoing colonoscopy.

Average treatment effect of robotic versus laparoscopic rectal surgery for rectal cancer.

BACKGROUND: The aim of this study is to estimate what would have happened if all patients treated with laparoscopy for rectal cancer had instead been treated with the robotic technique. METHODS: To estimate the average treatment effect (ATE) of the robotic technique over the laparoscopic approach, data from patients treated at two centres between 2007 and 2018 were used to obtain counterfactual outcomes using an inverse probability weighting (IPW) adjustment. RESULTS: This study enrolled 261 patients, of which 177 and 84 patients had undergone robotic surgery and standard laparoscopy, respectively. After IPW adjustment, the difference between the groups was similar in the pseudo-population. The average conversion rate would fall by an estimated 6.1% if all procedures had been robotic (p = 0.045). All other post-operative variables showed no differences regardless of the approach. CONCLUSION: ATE estimation suggests that robotic rectal cancer surgery could be associated with a lower conversion rate. The approach did not affect the post-operative morbidity rates or the operative time.

Correction to: Single-centre comparison of robotic and open pancreatoduodenectomy: a propensity score-matched study.

In the Abstract, in the Methods section the sentence "Of the 121 included patients, 78 underwent RAPD and 43 underwent OPD." Should read: Of the 121 included patients, 77 underwent OPD and 44 underwent RAPD."

Single-centre comparison of robotic and open pancreatoduodenectomy: a propensity score-matched study.

BACKGROUND: Pancreatoduodenectomy for pancreatic head and periampullary cancers is still associated with high perioperative morbidity and mortality. The aim of this study was to compare the short-term outcomes of robot-assisted pancreatoduodenectomy (RAPD) and open pancreatoduodenectomy (OPD) performed in a high-volume centre. METHODS: A single-centre, prospective database was used to retrospectively compare the early outcomes of RAPD procedures to standard OPD procedures completed between January 2014 and December 2018. Of the 121 included patients, 78 underwent RAPD and 43 underwent OPD. After propensity score matching (PSM), 35 RAPD patients were matched with 35 OPD patients with similar preoperative characteristics. RESULTS: There were no statistically significant differences in most of the baseline demographics and perioperative outcomes in the two groups after PSM optimization with the exception of the operative time (530 min (RAPD) versus 335 min (OPD) post-match, p < 0.000). No differences were found between the two groups in terms of complications (including pancreatic leaks, 11.4% in both OPD and RAPD), perioperative mortality, reoperations or readmissions. Earlier refeeding was obtained in the RAPD group vs. the OPD group (3 vs. 4 days, p = 0.002). Although the differences in the length of the hospital stay and blood transfusions were not statistically significant, both parameters showed a positive trend in favour of RAPD. The number of harvested lymph nodes was similar and oncologically adequate. CONCLUSIONS: RAPD is a safe and oncologically adequate technique to treat malignancies arising from the pancreatic head and periampullary region. Several perioperative parameters resulted in trends favouring RAPD over OPD, at the price of longer operating time. Data should be reinforced with a larger sample to guarantee statistical significance.

Long-term functional follow-up after anterior rectal resection for cancer.

PURPOSE: This is a retrospective analysis including all of the patients that have undergone anterior resection for rectal cancer from January 1998 to December 2005 in two tertiary referral centers. The study aims to evaluate the long term functional results after low anterior resection and to identify the risk factors of postoperative bowel disorders. METHOD: Data were collected from the clinical records, and then the low anterior resection syndrome score which is a specific questionnaire to investigate the symptoms after surgery was submitted to the selected patients. Exclusion criteria were intra-abdominal rectal cancer, partial mesorectal excision, permanent stoma, recurrent local disease, and patients who declined the questionnaire. RESULTS: A total of 93 patients were included in the analysis with a median age at the diagnosis of 66 years. The median follow-up was 13.7 years, and low anterior resection syndrome was reported in 44 patients (47.5 %), with major manifestations in 19 patients (20.5 %), and minor symptoms in 25 patients (27 %). Age more than 70 years, tumor distance from the external anal verge, neoadjuvant treatment, and interval time of closing stoma are independent prognostic factors of functional disorders after surgery. CONCLUSIONS: Because of its great impact on the quality of life of these patients, it is necessary to early identify the syndrome trying to reduce its manifestations. Moreover, the symptoms seem to remain stable 1 year after surgery; hence, it is important to have an exhaustive, preoperative counseling and an integrated post-operative functional and rehabilitational follow-up in association with the oncologic pathway.

Ascaris lumbricoides: una causa de pancreatitis aguda / Acute pancreatitis due to Ascaris lumbricoides

La ascariasis es una infección parasitaria causada por un helminto de distribución global, con más de 1.4 billones de personas infectadas en el mundo. La mayoría de estas infecciones ocurren en países en vías de desarrollo de América latina y Asia. El helminto usualmente se aloja en el intestino delgado en forma silente pero puede causar obstrucción intestinal o peritonitis perforativa, siendo más común en la niñez. A su vez, puede migrar a través de la ampolla de Vater y producir pancreatitis, colecistitis, colangitis y, en forma menos frecuente, absceso hepático. El objetivo de nuestra comunicación es notificar un caso de pancreatitis aguda secundaria a Ascaris lumbricoides, siendo ésta una complicación infrecuente pero grave de una enfermedad endémica como la ascariasis.

Ascariasis is a helminthic infection of global distribution with more than 1.4 billion persons infected throughout the world. The majority of infections occur in the developing countries of Latin America and Asia. This helminth usually lives harmlessly in small intestine but can also cause intestinal obstruction or perforation peritonitis that is common in childhood. Ascaris can also migrate through ampulla of Vater to produce pancreatitis, cholecystitis, cholangitis and, rarely, hepatic abscess. The main goal of this article is to present a case of an acute pancreatitis due to Ascaris lumbricoides, an uncommon but severe complication of an endemic disease such as ascariasis.
