Risk factors for postoperative hypocalcemia.

Hypocalcaemia is one of the most common complications after thyroidectomy; however, it is still unclear what preoperative factors could predict this event. The aim of this study was to evaluate the role of risk factors for hypocalcaemia after total thyroidectomy (TT). Consecutive patients who underwent total thyroidectomyat our institution between January 2014 and January 2016 were enrolled. The clinical and pathologic characteristics and surgical details of normocalcemic and hypocalcemic patients were compared. Univariate and multivariate analyses to estimate risk ratio were assessed. A total of 328 patients underwent TT; histology revealed benign and malignant disease in 83 and 17% of cases, respectively. Central-compartment neck dissection (CCND) was performed in 36 subjects (10.9%). Parathyroid glands were observed in 23% (76) of specimens. Laboratory asymptomatic hypocalcaemia was observed in 92 (28%) patients; symptomatic hypocalcaemia occurred in 26 (7.9%). Transient hypocalcaemia has been observed in 48 (14.6%) patients; permanent hypocalcaemia occurred in two subjects (0.6%). On univariate analysis, malignant pathology (p < 0.001), CCND (p < 0.05), female gender (p < 0.001), presence of at least two parathyroid glands in specimens (p < 0.002), and operative time longer than 120 min (p < 0.05) were factors that significantly increased the risk of developing asymptomatic and transient hypocalcaemia. After logistic regression analysis, malignant pathology (p < 0.000; p < 0.001) and CCND (p < 0.005; p = 0.013) were the significant factors that affected the development of symptomatic and transient hypocalcaemia. The presence of malignant pathology and CCND was found to be significant risks factors for postoperative hypocalcaemia. In patients in whom this pathological features are present, attention should be paid to rapidly start an adequate therapy.

Quality of life and scar evolution after negative pressure or conventional therapy for wound dehiscence following post-bariatric abdominoplasty.

No studies have examined scars and quality of life after different treatments of wound dehiscence in patients undergoing post-bariatric abdominoplasty. Scars and quality of life of patients with postoperative wound dehiscence managed with negative pressure wound therapy (group A) and conventional wound therapy (group B) were reviewed 6 months after wound healing. Of 38 patients undergoing treatment for wound dehiscence after 203 abdominoplasty, 35 (group A = 14 versus group B = 21) entered the study. Wound healing in group A was significantly faster than group B (P = 0·001). Patients (P = 0·0001) and observers (P = 0·0001) reported better overall opinions on a scar assessment scale for group A. Better overall quality of life and general health satisfaction were observed in group A (P < 0·05). A significant correlation was observed between the World Health Organization Quality of Life scores and Patient and Observer Scar Assessment Scale scores (r=-0·68, P < 0·0001) in all 35 patients. Negative pressure wound therapy is feasible and effective in patients with wound dehiscence following post-bariatric abdominoplasty. An adequate post-treatment outcome is achieved compared with conventional wound therapy in light of a strong association found between worse patient scar self-assessment and poor overall quality of life, regardless of the received treatment.

Pre-operative clinical and instrumental factors as antireflux surgery outcome predictors.

Gastroesophageal reflux disease (GERD) is nowadays a highly prevalent, chronic condition, with 10% to 30% of Western populations affected by weekly symptoms. Many patients with mild reflux symptoms are treated adequately with lifestyle modifications, dietary changes, and low-dose proton pump inhibitors (PPIs). For those with refractory GERD poorly controlled with daily PPIs, numerous treatment options exist. Fundoplication is currently the most commonly performed antireflux operation for management of GERD. Outcomes described in current literature following laparoscopic fundoplication indicate that it is highly effective for treatment of GERD; early clinical studies demonstrate relief of symptoms in approximately 85%-90% of patients. However it is still unclear which factors, clinical or instrumental, are able to predict a good outcome after surgery. Virtually all demographic, esophagogastric junction anatomic conditions, as well as instrumental (such as presence of esophagitis at endoscopy, or motility patterns determined by esophageal high resolution manometry or reflux patterns determined by means of pH/impedance-pH monitoring) and clinical features (such as typical or atypical symptoms presence) of patients undergoing laparoscopic fundoplication for GERD can be factors associated with symptomatic relief. With this in mind, we sought to review studies that identified the factors that predict outcome after laparoscopic total fundoplication.

Relationship between postoperative venous thromboembolism and hemorrhage in patients undergoing total thyroidectomy without preoperative prophylaxis.

INTRODUCTION: The aim of the present study was to critically review the incidence of venous thromboembolism and postoperative hemorrhage in patients undergoing total thyroidectomy without preoperative prophylaxis. METHODS: A prospective electronic database of all patients undergoing total thyroidectomy over a six-year period within August 2013 in our medical unit was analyzed. The incidence of postoperative bleeding and Venous thromboembolism (VTE) was reviewed by subgrouping all patients according to a risk factor score (RFS) for VTE as outlined in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Best Practice Guidelines. RESULTS: An overall 1018 consecutive patients [244 men (24%, mean age 46 ± 13 years), 778 women (76%, mean age 44 ± 17 years)] underwent total thyroidectomy. Postoperative bleeding occurred in 8/1018 patients (0.8%). One out of 1018 (0.1%) patients also subcategorized according to the RFS had VTE. The incidence of VTE complication in the entire population was lower than the risk of postoperative bleeding (P < .0001). CONCLUSION: The risk of developing VTE in patients who undergo total thyroidectomy for benign and malignant diseases without preoperative prophylaxis is roughly 8-fold less than developing a potentially life threatening complication as postoperative bleeding. Until large well conducted prospective studies on the impact of preoperative prophylaxis on postoperative VTE and bleeding will clarify the issue, it is conceivable to propose the use of stockings and/or anticoagulants according to the individual patient risk factors.

Long term quality of life after laparoscopic antireflux surgery for the elderly.

BACKGROUND: Studies have previously shown laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients. The aim of the current study was to evaluate patients receiving laparoscopic antireflux surgery before and after 65 years of age and to assess their surgical outcomes and improvements in long term quality of life. METHODS: Patients were given a standardized symptoms questionnaire and the Short-Form 36 Health Survey for quality-of-life evaluation before and after laparoscopic total fundoplication. RESULTS: Forty-nine patients older than 65 years of age were defined as the elderly group (EG) whereas the remaining 262 younger than 65 years of age were defined as the young group (YG). CONCLUSIONS: In conclusion, laparoscopic total fundoplication is a safe and effective surgical treatment for gastroesophageal reflux disease generally warranting low morbidity and mortality rates and a significant improvement of symptoms comparable. An improved long-term quality of life is warranted even in the elderly.

The impact of age and oral calcium and vitamin D supplements on postoperative hypocalcemia after total thyroidectomy. A prospective study.

BACKGROUND: Hypocalcemia caused by transient or definitive hypoparathyroidism is the most frequent complication after total thyroidectomy (TT). We aimed to compare the impact of age and the clinical usefulness of oral calcium and vitamin D supplements on postoperative hypocalcemia after TT, and to determine which risk factors are important for hypocalcemia incidence. METHODS: Two hundred consecutive patients treated by TT were included prospectively in the present study. All patients supplemented oral calcium and vitamin D in the post-operative time. The data concerning symptomatic and laboratoristichypocalcemia were collected. RESULTS: Symptomatic hypocalcemia developed only in 19 patients (9.5%), whereas laboratory hypocalcemia developed in 36 patients (18%). The risk for postoperative hypocalcemia was increate 20-fold for patients older than 50 years. CONCLUSIONS: Age is significantly associated with postoperative hypocalcemia. Implementing oral calcium and vitamin D after total thyroidectomy can reduce the incidence of hypocalcemia related to surgery.

Hyaluronic acid and adhesions on polypropylene endoperitoneal mesh: an experimental study.

INTRODUCTION: The aim of this study was to verify the effectiveness of hyaluronic acid in preventing adhesion formation after endoperitoneal surgery in which prosthetic polypropylene mesh is placed directly on the viscera. METHODS: Forty albino rats were included in this study and the animals were randomized to the following 4 groups each with 10 rats: polypropylene prosthesis (PP), PP+hyaluronic acid (HA), Hertra prosthesis (HP), HP+HA. A large defect was created in the anterior abdominal wall of each rat and repaired in different ways. In the first group a polypropylene mesh was placed intraperitoneally, while, in the second group the peritoneal surface of the mesh was impregnated with HA. In the third group a Hertra 0 polypropylene rigid mesh was placed intraperitoneally and, in the fourth group, the peritoneal surface of the Hertra 0 mesh was impregnated with HA. Clinical controls on the animals were carried out at 1 month. Each group was divided into two subgroups in which the controls and the prosthetic explantation were randomly carried out at 3 and 6 months. Explanted prostheses were subjected to histological and immunohistochemical analysis, and examined for shrinkage. An assessment of adhesion formation was performed, evaluating the quantity and tenacity of the adhesions. RESULTS: We demonstrated higher levels of adhesions in rats with PP than in those with HP and lower levels in rats with a protective layer of hyaluronic acid. The amount of fibronectin in the periprosthetic fibrotic tissue and the histological score confirmed the previous data. CONCLUSIONS: Hertra 0 mesh with HA provided the best results in terms of physical stability and resistance to adhesion formation.

Ultrasound scalpel in thyroidectomy. Prospective randomized study.

OBJECTIVE: The ultrasonic scalpel is a surgical shear that uses high-frequency mechanical energy to enable simultaneous vessel sealing and tissue coagulation at the same time. We conducted a prospective randomized study to compare the outcome of total thyroidectomy using the ultrasonic scalpel versus standard clamp and tie (CT) procedure in terms of safety, operative time, overall drainage volume, complications, hospital stay. METHODS: Between January 2008 and December 2010, 200 patients (130 women, 70 men; mean age 46 years) undergoing thyroidectomy were randomized into two groups: group A, where CT technique were used, and group B, where the ultrasonic device was used. RESULTS: There was no significant differences between the two groups in terms of age, gender, indication for thyroidectomy, thyroid gland weight and diameter, histopathologic diagnosis, preoperative and postoperative serum calcium levels, postoperative complications and reoperative thyroid surgery. In group B there is a statistically significant reduction of the operative times (63 ± 9' vs 85 ± 15', P<0.001) and overall drainage volume (50 ± 20cc vs 70 ± 25cc, P<0.001) . CONCLUSIONS: The ultrasonic scalpel is safe, effective, useful, and time-saving alternative to the traditional suture ligation technique for thyroid surgery. They simplified total thyroidectomy, eliminating the need for clamp-and-tie maneuvers while achieving efficient hemostasis. Our study shows that the use of ultrasound in thyroid surgery reduces significantly surgical time and overall drainage volume. Furthermore, we also verified a decrease in hospitalization time, postoperative pain and blood loss, without increasing complication rates, for patients who underwent total thyroidectomy with the ultrasonically activated shear.
