Voice and Swallowing Disorders After Thyroid Surgery.

OBJECTIVE: The aim of the study was to evaluate voice and swallowing function following thyroid surgery, to identify dynamic changes during the follow-up period of 12-18 month and to find possible indicative signs of permanent or temporary vocal fold palsy. METHODS: All participants (N = 110) were prospectively enrolled from the preoperative thyroid surgery patients between September 2013 and December 2016. All subjects underwent preoperatively, first week and 12-18 month postoperatively videolaryngostroboscopy, filled in subjective evaluation of voice (voice handicap index, [VHI]) and swallowing (swallowing impairment score) complaints. Acoustic voice analysis (AVA), maximum phonation time (MPT) measurement and perceptual voice evaluation were conducted. In the presence of laryngeal damage, additional first and sixth-month follow-up visits were planned. Patients, whom we suspected laryngeal nerve damage, underwent laryngeal electromyography 4 weeks after the operation. RESULTS: On first postoperative week evaluation, no objective voice changes within patients with postoperatively intact laryngeal nerves were found. Subjective evaluations showed decline in VHI physical domain and increased strain in postoperative voice. Patients with postoperative nerve damage had a drastic decline in subjective voice quality (VHI all subscales and total score), AVA parameter jitter, MPT and perceptual voice quality. Subjective evaluation of swallowing revealed disturbances in all patients regardless of the nerve damage. We noticed remarkable differences in first week and first month visits between patients with permanent and temporary palsy in VHI total score and physical domain, MPT and perceptual breathiness and asthenia in voice. Regardless of the nerve injury, by the end of the follow-up period all changes had become statistically insignificant with the exception of perceptual evaluation of voice quality. CONCLUSIONS: Patients with postoperative laryngeal nerve damage experience substantial deterioration of both subjective and objective voice quality with more extensive impairment in patients with permanent paralysis. Thyroid surgery causes subjective swallowing changes irrespective of laryngeal nerve damage. In patients without laryngeal nerve damage, swallowing function improves following thyroidectomy. Possible indicators for permanent paralysis are delayed recovery in the values of MPT and jitter and persistent perceptual breathiness and asthenia.

Five-Year Outcome of Laparoscopic Sleeve Gastrectomy, Resolution of Comorbidities, and Risk for Cumulative Nutritional Deficiencies.

BACKGROUND AND AIMS:: The aim of this study was to evaluate the long-term (5-year follow-up) results of laparoscopic sleeve gastrectomy in terms of weight loss and obesity-related comorbidities, as well as the risk factors associated with postoperative nutritional deficiencies. MATERIAL AND METHODS:: The first 99 consecutive patients who underwent laparoscopic sleeve gastrectomy for the treatment of morbid obesity between October 2008 and August 2011 at Tartu University Hospital were followed prospectively in cohort study. The outpatient hospital follow-up visits were conducted at 3 months, 1 year, and 5 years postoperatively. At 5 years, the follow-up rate was 90.9%; 86 laparoscopic sleeve gastrectomy patients were included in final analysis. RESULTS:: The mean excess weight loss (%EWL) was 44.3% ± 13.0%, 75.8% ± 23.1%, and 61.0% ± 24.3% at 3 months, 1 year, and 5 years, respectively. A linear association between preoperative weight and weight at 5 years was found. Remission rates at 5-year follow-up for type 2 diabetes, hypertension, dyslipidemia, and obstructive sleep apnea were 68.8%, 32.7%, 27.4%, and 61.5%, respectively (all p < 0.05). There was a statistical difference (p < 0.05) in the dynamics of triglyceride, low-density lipoprotein, and high-density lipoprotein level at 5-year follow-up but the level of total cholesterol did not show significant improvement. The risk for cumulative iron, vitamin B12 deficiency, and anemia was 20%, 48%, and 28%, respectively. CONCLUSION:: In conclusion, laparoscopic sleeve gastrectomy ensured long-term excess weight loss 61.0% at 5 years. Laparoscopic sleeve gastrectomy has a long-term effect on significant improvement in the median values of triglycerides, low-density lipoproteins, and high-density lipoproteins, but not on total cholesterol levels. There is a risk of postoperative vitamin B12 and iron deficiency.

Prospective study evaluating the impact of severity of chronic pain on quality of life after inguinal hernioplasty.

PURPOSE: The definition of chronic pain after inguinal hernioplasty and the methods of its assessment vary a great deal, which make it complicated to conduct meta-analyses. The primary aim of the present prospective study was to evaluate at which pain severity degree the quality-of-life scores will be reduced. METHOD: A prospective study of patients operated for inguinal hernia was conducted. A pain questionnaire and a quality-of-life (QoL) questionnaire were completed. RESULTS: Altogether, 370 patients were investigated and included in analysis. Of them, 33.8% experienced pain during different activities. Compared to the non-pain response group, significantly lower QoL scores for the Bodily pain domain were reported by patients who gave 1, 2, or 3 positive responses to the pain questionnaire. Patients with no pain as well as patients who gave 1 positive response to the pain questionnaire and whose VAS score was ≤20 had similar QoL scores for all domains. Patients who gave 1 positive response to the pain questionnaire and whose VAS score was >20, and patients who gave two or more positive responses to the pain questionnaire, showed significantly lower QoL scores in most of the domains compared with the non-pain group. When the patients who gave 1 positive response to the pain questionnaire and whose VAS score was ≤20 were excluded from the group of patients with pain, the rate of chronic pain was 19.7%. Considering the above result, the reduction in the rate of chronic pain from 33.8 to 19.7% was statistically significant. CONCLUSION: Pain scores 20 mm or less on the VAS (0 to 100 mm) have no impact on the patients' quality of life. Uniform assessment methods of chronic pain should be developed to improve the quality of research.

Three-Year Results of a Single-Centre Single-Blinded Randomised Study Evaluating the Impact of Mesh Pore Size on Chronic Pain after Lichtenstein Hernioplasty.

BACKGROUND AND AIMS: The aim of the present study was to determine whether usage of mesh with larger pores, compared with mesh with smaller pores, would result in a decreased rate of chronic pain at 3-year follow-up. According to earlier published short-term results, differences in mesh pore size do not influence the rate of chronic pain. MATERIAL AND METHODS: The patients were randomized into two study groups for which meshes with similar weight but different pore size were used: the UM group received Ultrapro mesh (pore size 3-4 mm) and the OM group received Optilene LP mesh (pore size 1 mm). Pain scores were measured on a visual analog scale. The feeling of a foreign body was a yes-or-no question. RESULTS: A total of 65 patients in the UM group and 63 patients in the OM group were included in analysis. Of the patients, 33.9% in the UM group and 15.9% in the OM group reported having experienced pain during different activities at 3-year follow-up (P = 0.025). Comparison with the results of 6-month follow-up (46.3% in the UM group, 34.3% in the OM group) showed that the rate of chronic pain had decreased significantly in the OM group (P = 0.009) but not in the UM group (P = 0.113). The feeling of a foreign body in the inguinal region was experienced by 23.1% of the patients in the UM group and by 15.9% in the OM group (P = 0.375). There was one hernia recurrence in the OM group. Severe preoperative pain and younger age were identified as risk factors for development of chronic pain. CONCLUSIONS: Mesh with larger pores, compared with mesh with smaller pores, has no advantages in reducing the rate of chronic pain. We speculate that the reason for the higher rate of chronic pain in the study group where the mesh with larger pores was used might have been the different composition of the meshes at implantation. Also, it is possible as development of chronic pain after inguinal hernia repair is multifactorial, we failed to find a plausible explanation for this difference. Low recurrence rates were achieved with both meshes used in our study.

Methods of emergency surgery in high-risk stigmata peptic ulcer hemorrhage.

AIM: The choice of emergency operative methods in management of peptic ulcer hemorrhage (PUH) is controversial. The aim of this study was to analyze the patient characteristics, surgical methods and treatment outcome of patients with PUH during 10 years. METHODS: Of the 953 admitted PUH patients all 67 (7.0%) operated cases had high-risk stigmata PUH (Forrest classification). These patients were grouped and their data were compared under two 5-year periods: period I - 32 patients (2003-2007) and period II - 35 patients (2008-2012). RESULTS: The majority of the patients had giant ulcer (diameter ≥ 2 cm) hemorrhage at 75.0% (24/32) and 94.3% (33/35) during study periods I and II, respectively (P=0.04). Giant duodenal and gastric ulcers for PUH were operated in 16 and 8 vs 27 and 6 during periods I and II, respectively. Ulcer exclusion or ulcerectomy combined with definitive acid reducing surgery was applied in 68.7% (22/32) and 71.4% (25/35) of the patients, respectively, without early recurrent hemorrhage. Postoperative in hospital mortality in the 10-year study period was 6.0% (4/67); 2.1% (1/48) of the patients died after definitive operations and 15.8% (3/19) (P=0.04) died after non-definitive operations. CONCLUSION: The surgical treatment of high-risk stigmata PUH was mainly associated with giant, particularly giant duodenal ulcer. As a rule, ulcer exclusion or ulcerectomy as hemorrhage control, combined with definitive surgery, was applied in the majority of the cases with an in hospital mortality of 2.1%.

Definition, prevalence, and outcome of feeding intolerance in intensive care: a systematic review and meta-analysis.

Clinicians and researchers frequently use the phrase 'feeding intolerance' (FI) as a descriptive term in enterally fed critically ill patients. We aimed to: (1) determine what is the most accepted definition of FI; (2) estimate the prevalence of FI; and (3) evaluate whether FI is associated with important outcomes. Systematic searches of peer-reviewed publications using PubMed, MEDLINE, and Web of Science were performed with studies reporting FI extracted. We identified 72 studies defining FI. In 33 studies, the definition was based on large gastric residual volumes (GRVs) together with other gastrointestinal symptoms, while 30 studies relied solely on large GRVs, six studies used inadequate delivery of enteral nutrition (EN) as a threshold, and three studies gastrointestinal symptoms without reference to GRV. The median volume used to define a 'large' GRV was 250 ml (ranges from 75 to 500 ml). The pooled proportion (n = 31 studies) of FI was 38.3% (95% CI 30.7-46.2). Five studies reported outcomes, all of them observed adverse outcome in FI patients. In three studies, respectively, FI was associated with increased mortality and ICU length-of-stay. In summary, FI is inconsistently defined but appears to occur frequently. There are preliminary data indicating that FI is associated with adverse outcomes. A standard definition of FI is required to determine the accuracy of these preliminary data.

Incidence and risk factors of surgical wound infection in children: a prospective study.

BACKGROUND AND AIMS: to establish the incidence and risk factors of surgical site infection (SSI) in children operated in the Department of Paediatric Surgery of the Clinic of Surgery of Tartu University Hospital. MATERIAL AND METHODS: the data of wound healing were obtained for 589 children operated between 15 March 2003 and 31 March 2005. The operations were divided into general surgical (451), orthopaedic (70) and urological (68). The surgical wounds were classified as clean (442), clean-contaminated (96), contaminated (36) and dirty-infected (15). Univariate and multivariate analyses were performed to identify risk factors. RESULTS: There were 7 SSI cases, overall rate being 1.2%. Superficial wound infection occurred in 5 cases and deep wound infection occurred in 2 cases. There was no organ/space infection. SSI was significantly more frequent in the case of contaminated and dirty-infected compared with clean or clean-contaminated operations, 7.8% and 0.6%, respectively (p = 0.0008). Wound infection endangered more children who had operation related complications compared with non-complicated cases, 11.1% and 0.4%, respectively (p < 0.0001).
