Surgical treatment of advanced thyroid cancer invading the trachea, A case presentation and review of literature
H Davary ,
Volume 57, Issue 2 (5-1999)
Abstract
Differentiated carcinoma of the thyroid occruing within the gland is generally not regarded as an aggressive tumor however, when the tumor extends beyond the gland's capsule and onto adjacent structures, its prognosis worsens. During the past three decades such locally invasive thyroid cancer has been studied, specifically concerning invasion into the airway. Progress in tracheal operations in the past 20 years has changed remarkably in terms of the operative methods and indications for thyroid carcinoma invading the trachea. Resection and primary reconstruction of the trachea invaded by carcinoma of the thyroid should be done in the absence of extensive metastases when technically, feasible. It offers prolonged palliation, avoidance of suffocation and an opportunity for cure. In carefully selected patient with massive regional involvement, radical excision laryngopharyngoesophagectomy and mediastinal tracheostomy is also appropriate. In this article, management of one patient with intraluminal involvement of trachea by thyroid carcinoma is presented and management of upper aerodigestive tract invasion by thyroid cancer reviewed.

Daryaei P, Vaghef Davari F, Mir M, Harirchi I, Salmasian H,
Volume 65, Issue 12 (3-2008)
Abstract

Background: Nasogastric tube (NG tube) usage was first described in 1921 by Levin. Surgeons routinely use NG tube in most esophageal resections. Considering the numerous complications caused by this tube, the uncertainty about its usefulness and the scarcity of studies conducted on the subject, particularly in esophageal cancer patients, we investigated the necessity of the NG tube in these cases.

Methods: This clinical trial was performed at the Cancer Institute of Imam Khomeini Hospital. Esophageal cancer patients were randomized into groups either with or without postoperative NG tube the latter group was also prescribed metoclopramide. Postoperative obstruction was the exclusion criteria. The operation was done by a team of surgeons using the surgical techniques of McKeown or Orringer. All patients received ranitidine, heparin and antibiotics postoperatively. All patients received postoperative chest X-ray and chest physiotherapy. The NG tube was inserted or reinserted for those with abdominal distention and/or repeated vomiting. The NG tube was pulled out after return of bowel movements. The variables recorded for each patient included the first day of flatus, the first day of defecation, the first day of bowel sound (BS) upon auscultation, duration of post-operative hospitalization, nausea and vomiting, abdominal distension, pulmonary complications, wound complications, anastomotic leakage and the need for placing/replacing the NG tube. Statistical analysis was performed using SPSS, v. 11.5.

Results: After randomization, the NG tube was inserted for 22 patients, and 18 patients had no NG tube. The incidence of anastomotic leakage was significantly higher in the NG-tube group. No significant differences between the two groups were found for other complications. The mean times until first passage of flatus, defecation and BS upon auscultation and the duration of post-operative hospitalization were not significantly different. The need for placing/replacing the NG tube was the same for both groups. There was no difference in the perioperative death rates between the two groups.

Conclusions: We conclude that the routine use of NG tubes after surgery is not recommended for all patients. NG tube should be used according to the specific needs of each patient. This protocol will protect patients from undesired complications.

Rezaii J, Esfandiari Kh, Khalili Pooya J, Tavakoli H, Abdolrahman R, Salamati P, Abouzari M,
Volume 66, Issue 6 (9-2008)
Abstract

Background: Hypopharyngeal cancer usually presents with cervical mass, hoarseness, radiated otalgia, and dysphagea in the advanced stages. Radical surgery followed by radiotherapy plays an important role in the treatment of patients with hypopharyngeal cancer. However, there is no general consensus as to which is the best method of reconstruction after surgical resection. The aim of this study was to evaluate the complications of pectoralis major myocutaneous flap (PMMF) and gastric pull-up (GPU) techniques to reconstruct a circumferential defect after laryngopharyngoeso- phagectomy.

Methods: We retrospectively reviewed the records of 64 patients who underwent radical surgery and reconstruction with either PMMF or GPU technique. Demographic characteristics, tumor location, proximal margin involvement, history of radiotherapy, presence of lymphadenopathy, cervical dissection, and postoperative complications such as fistula, anastomotic site stenosis, swallowing dysfunction, and stoma stenosis were compared between the two groups. Postoperative complications of the reconstruction methods were compared.

Results: A total of 64 patients, 43(67%) in GPU group and 21(33%) in PMMF group, were studied. The groups did not differ in demographic characteristics. The locations of the tumoral lesions were in larynx (n=7), proximal esophagus (n=5), posterior cricoid (n=5), pyriformis sinus (n=7), posterior wall (n=7), and miscellaneous (n=41). Six patients (6.3%) had proximal margin involvement, 19 patients (29.9%) had history of radiotherapy, 26 cases (40.6%) had lymphadenopathy, and 49 cases (76.5%) had cervical dissection. There was no significant difference between the two groups regarding stenosis or swallowing dysfunction rates, but fistula was seen lower following GPU compared with PMMF (p<0.001).

Conclusions: The GPU technique results in similar functional stenosis or swallowing dysfunction rates, but lower fistula compared with PMMF reconstruction.


Transhiatal versus transthoracic esophagectomy in the treatment of esophageal cancer patients: a study on 166 cases
Nikbakhsh N, Hashemi Sr, Moudi M,
Volume 68, Issue 4 (7-2010)
Abstract
Background: Esophageal cancer is one of the most lethal diseases in the world. It has a high prevalence in Iran, especially in the Northern provinces. The main treatment of esophageal cancer is surgery. There are two common surgical procedures for its treatment, Transhiatal esophagectomy and transthoracic esophagectomy. The aim of this study was to compare the results of above methods in esophageal cancer. Methods: This cross-sectional study was done on patients with pathologic diagnosis of esophageal cancer that referred to surgery ward of Shahid Beheshti Hospital, in Babol, Iran in 2002-2008. Patients according to the location of tumor and physical status were undergone transhiatal or transthoracic esophagectomy. Demographic and surgical findings were recorded. The patients were matched according to age, sex, weight loss, serum albumin level and hemoglobin concentration in two groups. Results: Fifty nine percent of patients were under transhiatal esophagectomy and 41% were under transthoracic esophagectomy (n=166). Morbidity did not show significant difference (p=0.636) between transhiatal (42.9%) and transthoracic (47.1%) methods. Duration of surgery (min) in transhiatal method (180.7±35.1) was significantly (p<0.0001) lower than the transthoracic one (226.7±54.2). Duration of admission (days) did not show significant difference (p=0.44) between transhiatal esophagectomy (8±4.9) and the other method (8.5±1.6). Mortality in 30 days after surgery did not show significant difference (p=0.489) between two groups (4.1% against 7.4%). Conclusions: Based on our study, duration of surgery in transhiatal esophagectomy was lower than transthoracic method. Other parameters include morbidity, mortality, and duration of admission had not significant difference between two groups.

Volume 77, Issue 12 (3-2020)
Abstract
Background: Arterial pressure is one of the most important physiological variables and often needs to be monitored repeatedly or continuously in perioperative period. Arterial pressure monitoring is one of the standard monitoring in operating room. During general anesthesia, blood pressure can be measured by using a noninvasive arterial pressure method or continuous invasive arterial pressure by an invasive arterial line. Comparison of invasive measurements in the patient’s candidate to esophagectomy has not been assessed. The aim of this study was to compare invasive and noninvasive blood pressure in these patients.
Methods: In a prospective, cross-sectional, observational study, 42 hemodynamically stable patients candidate for esophagectomy under general anesthesia in supine position were evaluated at Urmia Imam Khomeini Hospital operating room from June 2017 to April 2018. The patients had American Society of Anesthesiologists (ASA) physical status II or III and the patients who had complete heart block and marked arterial blood pressure differences greater than 10  mmHg in the two arms were excluded. After induction of anesthesia and patients monitoring, the radial artery was cannulated for invasive blood pressure monitoring and noninvasive blood pressure was measured via the arm cuff on the other hand at the four-time intervals: after radial artery cannulation (T1), during release of esophagus (T2), during anastomosis (T3) and at the end of operation (T4).
Results: The mean difference between indirect and direct systolic blood pressure was 0.85±2.93, -8.42±2.9, 6.50±3.60 and 2.67±2.6 mmHg and for diastolic blood pressure was 3.53±2.67, 4.57±2.22, 2.10±2.58 and 1.03±1.53 mmHg respectively, at the T1 to T4. At the all-time intervals, there were no statistically differences between systolic and diastolic blood pressure measurement regarding invasive and noninvasive blood pressure (P=0.77)
Conclusion: Noninvasive arterial blood pressure showed acceptable agreement with invasive measurements for systolic, diastolic and mean pressure. According to fhe finding of this study, there were no statistical differences between systolic and diastolic blood pressure measurement regarding invasive and noninvasive blood pressure and these two methods can be used in selected patients.
