Effects of Ankaferd on Anastomotic Healing of Colon

ABSTRACT Background: Ankaferd (Ankaferd blood stopper®, ABS) is a recently developed topical hemostatic agent. ABS is a standardized mixture of the plants Thymus vulgaris, Glycyrrhiza glabra, Vitis vinifera, Alpinia officinarum, and Urtica dioica. Through its effects on the endothelium, blood cells, angiogenesis, cellular proliferation, vascular dynamics, and cell mediators; Ankaferd plays a part in inflammation and hemostasis processes. The aim of this experimental study is to assess the effects of ABS on the left colonic anastomoses under normal, septic, and ischemic conditions. Methods: Forty-eight Wistar Albino male rats were divided into six weight-matched equal groups: A, anastomosis in normal condition (n = 8); AA, anastomosis with ABS in normal condition (n = 8); AS, anastomosis in septic condition (n = 8); AAS, anastomosis with ABS in septic condition (n = 8); AI, anastomosis in ischemic condition (n = 8); and AAI, anastomosis with ABS in ischemic condition (n = 8). Blood and tissue samples were taken for the histopathological and biochemical studies after the anastomotic bursting pressures were measured. Results: Higher hydroxyproline levels (p = .048) and angiogenesis (p = .038) were observed in the sepsis-induced rats compared to the control group. The inflammatory activity, fibrosis, and granulation were comparable in all experimental groups. Ankaferd improved the angiogenesis under septic conditions (AAS) when compared to the control group (AI; p = .038). Conclusions: ABS may support anastomotic healing in septic conditions. Topical ABS application controlling the mucosal bleeding at the cut ends of the colon may also improve the anastomotic wound healing by means of increasing mechanical strength and positively affecting angiogenesis. Further studies shall focus on the clinical importance of those findings.

Effect of energy-based devices on voice quality after total thyroidectomy

Voice alteration is an important complication of thyroid surgery and is closely related to patients’ quality of life. There are no studies analyzing effect of energy-based devices (EBD) on voice quality (VQ). Aim of this prospective study is to evaluate impact of sutureless total thyroidectomy performed with EBDs on objective voice parameters of patients without recurrent laryngeal nerve (RLN) and/or external branch of superior laryngeal nerve (EBSLN) injury. Sixty patients underwent total thyroidectomy with meticulous dissection of EBSLN. Patients were assigned to Group L (Ligasure™), Group H (Harmonic), or Group C (Conventional) through random ballot. For analysis of alteration in VQ, digital videolaryngostroboscopy (VLS), voice handicap index (VHI), multidimensional voice program (MDVP), and electroglottography (EGG) were used. VLS was performed by 70°-angled indirect laryngoscopy and evaluation was standardized by VLS scale and laryngeal function scoring. This study is registered on clinicaltrials.gov with number NCT01865006. Forty eight patients were female. There was no difference on demographic data. On post-operative laryngoscopic examination, none of the patients had vocal fold palsy. When mean VHI scores at post-operative 1st week and 2nd month were compared to pre-operative values for each groups, groups L and H demonstrated a significant increase in VHI in the early post-operative evaluation, while there was no significant increase for group C. No significant increase was seen in late post-operative period compared to pre-operative period for any groups. In the early post-operative period, VQ is better with the conventional technique than EBDs; however, in late post-operative period, VQ is detected better in EBDs (especially in Group L) than the conventional technique, but no statistical difference was observed.

Extended Pancreaticoduodenectomy for a Huge Cystic-Cavernous Lymphangioma: A Case Report

CONTEXT Cystic-cavernous lymphangioma is a rare cystic tumor especially for adults and pancreas. CASE REPORT We reported a case of a 33-year-old woman who presented with a visible and palpable abdominal mass found to be a huge lymphangioma of the pancreas. An abdominal magnetic resonance imaging (MRI) showed a multiloculated, lobulated T1 hypo/hyper, T2 hyperintense cystic mass extending from right subhepatic space to the pelvis measuring 155x167x100 mm. A pancreaticoduodenectomy was performed encompassing the distal stomach and a segment of the transverse colon, because of their close, inseparable relationship to the mass. The cystic mass was histopathologically diagnosed as partly cavernous and partly cystic lymphangioma. CONCLUSION To our knowledge this is the first case of pancreatic lymphangioma requiring additional organ resection besides a standard pancreaticoduodenectomy. To reduce recurrences, we recommend a complete resection for this pathology, even though its benign nature.

Bupivacaine application reduces post thyroidectomy pain: Cerrahpasa experience

BACKGROUND We aimed to evaluate the impact of bupivacaine administration into the surgical field after total thyroidectomy on post-operative pain and analgesic requirement with a double-blind, prospective, clinical and randomized study. METHODS The study was performed between 2010 and 2011. Pain assessment was performed with the visual analog score (VAS). Patients were pre-operatively, randomly divided into two groups to receive either bupivacaine or saline. One group received a 10-mL of bupivacaine solution while the other group was treated with the same volume of 0.9% NaCl through the drain after completion of total thyroidectomy procedure. All patients were anesthetized and operated with the same anesthesia and surgical team. RESULTS Ninety-one patients (20 males) were included in the study. No patient dropped out of the study during the procedures. No mortality was seen. The VAS scores were significantly lower in the bupivacaine administered group at post-operative minute 30 (3.7±3.2 vs. 5±2.9; P=0.03), hour one (3.04±2.4 vs. 4.2±2.8; P=0.04), and hour eight (1.8±2.04 vs. 3.2±2.1; P=0.005). Thirteen patients required analgesia during their hospital stay in the bupivacaine group while this number was twenty-two in the saline group (P=0.005). CONCLUSIONS Local bupivacaine administration into the surgical field after total thyroidectomy reduces pain and analgesic requirement during the hospital stay.

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.

Missed thyroid gland after total thyroidectomy

Missed gland is an extremely rare condition. It is a mediastinal thyroid mass found after total thyroidectomy. We report a case of missed gland. The patient underwent total thyroidectomy due to multinodular goiter and thyroid stimulating hormone levels did not increase after surgery. Pathological tests revealed a micropapillary carcinoma. Thyroid ultrasonography and scintigraphy scan revealed mediastinal thyroid mass. The patient underwent redo surgery without sternotomy and there was no morbidity after the second surgical procedure. Most missed thyroid gland cases are due to incomplete removal of plunging thyroid goiter during total thyroidectomy. They also can be attributed to a concomitant, unrecognized mediastinal goiter, which is not connected to the thyroid gland with vessels or a thin fibrous band. It should be noted that absence of signs like mediastinal mass or tracheal deviation in preoperative chest X-ray does not exclude substernal goiter. The presence of a missed thyroid gland should be kept in mind when postoperative thyroid stimulating hormone levels remain unchanged.

Prediction of Postoperative Vocal Fold Function After Intraoperative Recovery of Loss of Signal: Prediction of RLN Injury After Thyroidectomy

This multicenter study aimed to 1) evaluate early postoperative vocal fold function in relation to intraoperative amplitude recovery, and 2) determine optimal absolute and relative thresholds of intraoperative amplitude recovery heralding normal early postoperative vocal fold function, both after segmental type 1 and after global type 2 loss of signal (LOS).

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 (LigasureTM 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 patients 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.

The effect of thyroid gland weight on early complications in total thyroidectomy: Cerrahpasa experience

In this study we aimed to show whether thyroid gland weight has an effect on early and late complications in thyroidectomy done in an experienced center. 721 patients in Istanbul University Cerrahpaşa Medical Faculty General Surgery Department, in whom sutureless total thyroidectomy with vessel sealing devices were done, were retrospectively evaluated from January 2012 to December 2015. Reoperations, plonjan goiter, patients with capsule invasion and lymph node metastases who were operated due to thyroid cancer were excluded in the study. Demographic data, operation indications, operation duration, incision length, postoperative complications of the patients were recorded. The complications were recurrent nerve paralysis, hypocalcemia, hematoma and wound infection. These complications were compared according to the thyroid gland weight separately. Also, each complication group was divided into four groups, according to thyroid gland weight, as below 30 grams, 30-60 grams, 60-90 grams and heavier than 90 grams. The effect of thyroid gland weight on postoperative complications was evaluated. 22.2 % of the patients (n=160) were males and 77.8 % (n=561) were females. Mean age of the patients was 48,58±SD (18-85) years. Recurrent laryngeal nerve paralysis was seen in 5.68% (n=82) of the 721 patients, to whom vocal cord examination was done. Hypocalcemia symptoms in 5.54% of the patients (n=40), wound infections in 0.97% (n=7) of the patients and hemorrhage in 0.69% (n=5) of the patients were seen. Mean thyroid gland weight in patients with thyroid surgery complication was 56.1±SD (15-315) grams, while it was 56,94±SD (20-795) grams for noncomplicated thyroid surgery. The complications were divided into four groups. When these groups were compared according to thyroid gland weight separately, it was seen that thyroid gland weight does not affect early complications (p >0,5). Total thyroidectomy, when done in an experienced center, is the suggested surgery, which has 1% complication rate and the least recurrence rate. In our study, there was no statistically significant difference. This may be due to lighter thyroid gland weights in our study.

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 131I 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 131I 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.
