Experience of an endocrine surgeon in laparoscopic transperitoneal adrenalectomy

Background Laparoscopic adrenalectomy (LA) is currently recognized as the gold standard for the treatment of most adrenal lesions, with a high safety and feasibility profile. This study aimed to present the extensive experience of a specialized endocrine surgeon in LA in a relatively large series of patients. Methods A total of 116 LAs performed from June 2009 to 2018 were evaluated in terms of adrenal pathologies, perioperative management, complications, conversions, tumor size, operative time, and learning curve. The learning curve was assessed using the cumulative sum (CUSUMOT) technique. Results Of 116 LAs, 107 (92.2%) were completed successfully, 77 (72%) of which were for Cushing's syndrome (n = 43, 55.8%), pheochromocytoma (n = 26, 33.8%), and Conn's syndrome (n = 8, 10.4%). Conversion was required in 9 cases (7.8%), the most common cause being limited space complicating dissection (n = 3). The mean operative time for successful LAs (unilateral 85, bilateral 22) was 74.7 min (range 40-210 min) and the mean hospital stay was 1.7 days (range 1-5 days). Gender, tumor size and body mass index were found to have no significant relationship with the operative time (p > 0.05). Postoperative normalization in hormone profiles was obtained in all patients but one. Aside from grade-I port-site infections in four patients (3.7%), no postoperative major complications and 30-day mortality were observed. On the CUSUMOT graph, the learning period covered the first 34 operations. Conclusions Laparoscopic adrenalectomy is safe and advantageous, but requires a dedicated team involving experienced endocrine surgeons who have achieved competency after completion of the learning curve

Foreign body: A sewing needle migrating from the gastrointestinal tract to pancreas

Of all ingested foreign bodies, 2.4% comprise of sewing needles. Through perforation of gastrointestinal tract, which occurs in 1% of cases, they can migrate into the liver and pancreas. Foreign bodies in pancreas should be considered in the differential diagnosis of chronic abdominal pain. Computed tomography scans provide valuable information for the localization of the lesion, which guide the surgeon during the operation. Secondary to foreign bodies that migrate to the pancreas, complications with high mortality such as pancreatitis, pseudoaneurysm, and pancreas abscess can be seen. Thus, for this patient group, diagnostic laparoscopy is recommended, considering its advantages of decreased postoperative pain, decreased wound infection, and faster recovery time. Here we present a case of a 23-year-old female patient, from whom an ingested needle that migrated from the back wall of the stomach to the pancreas was extracted by laparoscopic surgery

Adrenal angiosarcoma

Adrenal angiosarcoma is an uncommon neoplasm that derives from the vascular endothelium; due to its biological behavior, it should be distinguished from other adrenal tumors. We herein report a case of a 57-year-old woman with diagnosis of an adrenal tumor that was suspected to be malignant. The specimen was histopathologically proved to be an angiosarcoma. The patient was suffering from right upper quadrant pain; after laboratory and radiological workup, a non-functioning right adrenal mass, 14 cm in size, was recognized. A right subcostal incision was made, and adrenalectomy was performed successfully with tumor-free surgical margins. Two months after the operation, a positron emission tomography-computed tomography scan was ordered for follow-up. No tumor tissue or any other metastatic foci remained. The patient had been referred to our medical oncology department and underwent retroperitoneal radiotherapy. However, unfortunately, the patient died due to cardiac insufficiency during the follow-up period

Is Nerve Monitoring Required in Total Thyroidectomy? Cerrahpasa Experience

Thyroidectomy is an elective operation performed in an anatomically complex region in which certain structures are responsible for vital functions and special senses. This study aims to compare the effects of two different technical approaches-nerve dissection combined with intraoperative nerve monitoring (IONM) and no nerve identification-on recurrent laryngeal nerve (RLN) damage in total thyroidectomy. One hundred and sixty-one consecutive cases that underwent total thyroidectomy and 322 RLN under risk were evaluated. In group 1 (n=162), nerve dissection combined with IONM was performed, whereas no RLN identification was performed in group 2 (n=160). While the duration of operation in group 1 (34.23 +/- 12.21 min) was statistically shorter than that in group 2 (36.98 +/- 16.79 min, p=0.017), there was no significant difference between groups related to RLN palsy (group 1 n=10, group 2 n=7). Use of IONM was found only to shorten the duration of operation. According to our presented experience, there is no benefit of IONM-combined routine dissection of RLN during total thyroidectomy on the prevention of RLN palsy

Silk suture reaction in thyroid surgery

Silk suture reaction (i.e.,a benign granulomatous inflammatory foreign body reaction) is a rare complication of thyroid surgery. Here, two cases of post-thyroidectomy suture reaction are presented. Both of the patients were female, one is 48 and the other is 34 years old. The patients were presented with neck swelling and leakage of serous fluid from the Kocher's incision. Both patients had normal free T-4, free T-3, and TSH values. The 48-year-old female patient had a right subtotal and left near-total thyroidectomy 6 years ago and the other had bilateral total thyroidectomy 6 years ago. In the physical examination a mobile, painless, red, swelling was palpated in front of neck. In the ultrasound of both patients, a heterogeneous nodule with hypoechoic rim was seen, however, in scintigraphy no radiopharmaceutical involvement was observed in thyroid region. Due to suspicion of thyroid malignancy, a fine needle aspiration biopsy was performed and foreign body reaction was revealed cytologically. A suture reaction can vary from an erythematous swelling to chronic granulomatous reaction. The time interval between the operation and formation of suture reaction was 6 years in both of the cases thus these patients were considered as chronic patients. Foreign body reaction diagnosis was confirmed with fine needle aspiration biopsy. It is important to diagnose these chronic inflammation cases since these cases can mimic recurrence in thyroid malignancies. A post-thyroidectomy suture reaction is diagnosed cytologically with fine needle aspiration biopsy and by surgical removal of suture, this chronic inflammatory reaction can be cured

Skin metastasis on the neck: an unusual presentation of recurrence of papillary thyroid carcinoma

Skin metastasis of papillary thyroid carcinoma (PTC) is rare. Here, two cases of skin metastases of PTC are presented. Both of the patients were females, one is 83 and the other is 65 years old. The patients were admitted to the hospital with a movable skin lesion on anterior neck region. Free T3 and T4 levels were in normal levels and TSH levels were low in both patients. The 83-year-old patient underwent total thyroidectomy due to papillary thyroid cancer and received I-131 ablation therapy and then thyroid suppression therapy. After the surgery, the patient lived without evidence of disease for 3 years and then skin metastasis occurred. The 65-year-old patient had a total thyroidectomy 5 years ago due to PTC then neck dissection due to metastasis 3 years later and then received I-131 ablation therapy. Thyroid ultrasonography of both patients showed hypoechoic nodules with central vascularization. In the histological examination of both patients, cystic lesions filled with papillary structures were seen. Fine needle aspiration biopsy (FNAB) taken from both patients were papillary carcinoma with solid trabecular pattern. PTC tends to metastasize to regional lymph nodes but distant metastasis is rare. When distant metastasis develops, prognosis of the disease is poor. Therefore, skin metastasis of papillary thyroid cancer is a poor prognostic factor. If the patient does not have a thyroid malignancy history, diagnosis of PTC metastatic to the skin may be difficult since primary skin tumors such as apocrine tumors have similar histopathological features. However, in the presented cases since there was a PTC history, the diagnosis was easier with the help of histopathological examination. Skin metastasis of PTC should be kept in mind when differential diagnosis of atypical skin lesions are made especially in the patients with thyroid malignancy history

Comparison of Tc-99m pertechnetate images with dual-phase Tc 99m MIBI and SPECT images in primary hyperparathyroidism

Background: The purpose of this study was to evaluate the value of Tc-99m pertechnetate planar, dual-phase MIBI and MIBI-SPECT images in the determination and localization of parathyroid lesions. Materials and Methods: In this study, 38 patients who underwent operation for primary hyperparathyroidism were included. Tc-99m pertechnetate planar-pinhole imaging of the neck and then MIBI planar and SPECT images in supine position was performed. Late SPECT images were acquired 120 minutes after the injection. Early and late MIBI images were quantitatively evaluated. Results: Of the 38 patients, 30 of them had adenoma, 2 patients had hyperplasia and 6 of them were normal on planar images. Thirty-four of 38 patients were positive on SPECT images. SPECT images of the patients with positive results were matched with pathology results. Conclusion: As a result, Tc-99m pertechnetate planar-pinhole, Tc-99m MIBI planar and SPECT images are useful for localization of parathyroid lesions especially in multinodular thyroid gland. However, US or CT images are necessary for more accurate localization and Tc-99m pertechnetate images are useful for interpreting and comparing with the early and late MIBI images

REOPERATIONS AND MORBIDITY IN THYROID SURGERY

Objective: Due to adhesions and distorted anatomy resulting from previous operations, reoperations are associated with increased complication rates. This study aims evaluate the morbidity in reoperative thyroid surgery

A rare case of non-surgical vocal cord paralysis: Vocal cord hematoma

Although vocal cord paralysis (VCP) following thyroidectomy is primarily associated with surgical trauma, it is not the sole etiology. Vocal cord paralysis following thyroidectomy can be caused by a vocal cord hematoma with an incidence of 1.4% due to direct injury during orotracheal intubation. In this article, we present a case of VCP caused by vocal cord hematoma. A 32-year-old male patient who has been receiving propylthiouracil treatment for toxic multinodular goiter since 10 years was admitted to our hospital to be operated because of persisting complaints. The patient was hospitalized for sutureless thyroidectomy after he became euthyroid. Preoperative fiberoptic laryngoscopy performed by the ear, nose, and throat department revealed bilaterally motile vocal folds and a completely open airway. Patient underwent sutureless total thyroidectomy with a vessel sealing device (Ligasure (TM) LF1212, Covidien, CO), and a minivac drainage system was placed in the thyroid lodge. On the morning of the first postoperative day, 50 mL of serosanguinous fluid was drained. The patient's voice was normal, and there was no ecchymosis. Postoperative fiberoptic laryngoscopy revealed a hematoma near the right vocal fold and paralysis of the right vocal fold; however, the airway was open. It should be kept in mind that VCP is not solely due to surgery but can also result from intubation, as observed in this case
