Introduction: Hemodynamic disturbance is a common problem in patients undergoing thyroid surgery. It may be due to episodic increases in thyroid hormones (thyroid storm) or stimulation of the carotid sinus baroreflex. The aim of the present study was to investigate effectiveness of the pre-operative oral Clonidine on reducing these hemodynamic changes during total thyroidectomy surgery.

Background: Controversies in terms of efficacy and postoperative advantages surround stapled esophagogastric anastomosis compared with the hand-sewn technique as a treatment for patients with esophageal cancer. The purpose of this study was to compare the clinical outcomes of hand-sewn end-to-side esophago-gastrostomy and side-to-side stapled cervical esophagogastric anastomosis after esophagectomy for the aforementioned patients.

Methods: This retrospective cohort study involved examining the medical records of 433 patients who underwent transhiatal esophagectomy for esophageal cancer from March 2010 to March 2016.

Background: Transient hypocalcemia due to parathyroid gland or vessel manipulation is a common complication following thyroidectomy. Considering the role of 25-hydroxyvitamin D (25(OH)D) in calcium hemostasis, this study aimed to evaluate the effect of preoperative vitamin D supplementation on hypocalcemia incidence in thyroidectomy patients.

Methods: In this randomized clinical trial, 100 patients scheduled for total thyroidectomy and suffering from preoperative moderate or severe vitamin D deficiency were enrolled.

Objectives: To evaluate the efficacy of the chest tube drainage (CTD) and the needle aspiration (NA) in the treatment of primary Spontaneous pneumothorax (SP).

Methods: In a randomized controlled trial, seventy patients suffering SP were divided equally into two subgroups, as follows: (A) CTD and (B) NA. The immediate and one-week rate of the treatments was the primary endpoints.

Background: LigaSure® Small Jaw (LSJ) has been recently introduced as an energy-based vessel sealing device, which has provided better intraoperative and postoperative outcomes in thyroidectomies, compared to conventional technique. In the current study, we aimed to examine the efficiency of hand-sewn and LSJ thyroidectomy, based on operation time and perioperative complications.

Methods: All patients with the diagnosis of multinodular goiter, thyroid cancers, retrosternal goiter and other indications for thyroid surgeries, enrolled.

Objective: To assess the efficacy of intercostal nerve protection by intercostal muscle (ICM) flap in post-thoracotomy pain improvement compared to intracostal suturing.

Methods: In a randomized controlled trial, ninety-four patients undergoing posterolateral thoracotomy surgery were divided into two subgroups. Intracostal sutures in isolation and in combination with ICM flap techniques were used for thoracotomy closure in both groups.
