The best surgical technique for pilonidal sinus disease (PSD) is still disputed. The objective of this prospective randomized study is to compare the short and long-term results of modified Limberg flap and Karydakis flap surgeries that have been widely used in recent years. Ninety one patients were included in the study. The patients were divided into two groups: modified Limberg flap (MLF; n = 46) and Karydakis flap (KF; n = 45). Preoperative findings of the patients, their surgical findings, and short and long-term postoperative findings were recorded and statistically compared. While no significant difference was discovered between the groups in terms of postoperative analgesic need, hospital stay, postoperative infection rate, drain stay time, painless sitting time, painless toilet-sitting time, and painless walking time, return to work or school time was shorter in the MLF group compared with the KF group (20.61 ± 7.89 days, 23.29 ± 6.42, respectively; P < 0.05). Cosmetically, the visual analog scale (VAS) of the KF group was significantly higher than that of the MLF group (VAS score 7.12 ± 1.28, 5.45 ± 1.77, respectively; P < 0.05). Considering recurrence rates, no statistically significant difference was found between the groups. Our study found out that short and long-term results of the MLF and KF procedures are similar. We believe both methods can be safely used in surgical PSD treatment given that in the MLF procedure, shorter return-to-work time is achieved, while the procedure provides better cosmetic results.

Multiple comorbidities and environmental factors increase the complications of incisional wounds in patients. It was demonstrated in previous prospective and randomized studies that negative pressure wound therapy (NPWT) reduced wound infection and other complications in clean, closed surgical incisions. In this case report, the Prevena incision management system was implemented on the clean, closed surgical incision of a 52-year-old female patient, who was given a renal transplantation from cadaver postoperatively in the operating theater. It was removed from the patient on the fifth day after the operation. Following the removal of Prevena, the wound and surrounding skin of the patient were observed. Wound healing was complete, and no skin lesion or tool-related complication was found around the wound due to NPWT. The Prevena NPWT system can be conveniently and safely implemented on the operational incision in renal transplant recipients in order to prevent surgical wound complications.

OBJECTIVES: To determine the serum and tissue levels of markers of impaired oxidative metabolism and correlate these levels with the histopathology and Alvarado score of acute appendicitis patients. METHOD: Sixty-five acute appendicitis patients (mean age, 31.4±12.06 years; male/female, 30/35) and 30 healthy control subjects were studied. The Alvarado score was recorded. Serum samples were obtained before surgery and 12 hours postoperatively to examine the total antioxidant status, total oxidant status, paraoxonase, stimulated paraoxonase, arylesterase, catalase, myeloperoxidase, ceruloplasmin, oxidative stress markers (advanced oxidized protein products and total thiol level) and ischemia-modified albumin. Surgical specimens were also evaluated. RESULTS: The diagnoses were acute appendicitis (n = 37), perforated appendicitis (n = 8), phlegmonous appendicitis (n = 12), perforated+phlegmonous appendicitis (n = 4), or no appendicitis (n = 4). The Alvarado score of the acute appendicitis group was significantly lower than that of the perforated+phlegmonous appendicitis group (p = 0.004). The serum total antioxidant status, total thiol level, advanced oxidized protein products, total oxidant status, catalase, arylesterase, and ischemia-modified albumin levels were significantly different between the acute appendicitis and control groups. There was no correlation between the pathological extent of acute appendicitis and the tissue levels of the markers; additionally, there was no correlation between the tissue and serum levels of any of the parameters. CONCLUSIONS: The imbalance of oxidant/antioxidant systems plays a role in the pathogenesis acute appendicitis. The Alvarado score can successfully predict the presence and extent of acute appendicitis.

A fine needle aspiration biopsy (FNAB) is the most valuable diagnostic procedure for pre‐operative discrimination of benign and malignant nodules. The Bethesda System for Reporting Thyroid Cytopathology provides standardised reporting and cytomorphological criteria in aspiration smears. The aim of the present study was to determine malignancy rates in nodules with different cytology results and evaluate the diagnostic value of Bethesda for variants of papillary thyroid carcinoma (PTC).

OBJECTIVE We aimed to evaluate the effect of bupivacaine and to compare the routes of administration of bupivacaine in the management of postoperative incision site pain after thyroidectomy. MATERIAL AND METHODS Consecutive patients who were planned for thyroidectomy surgery were randomized into three groups of 30 patients each: Group 1 (control group): standard thyroidectomy surgery without additional intervention; Group 2 (paratracheal infiltration with bupivacaine): following thyroidectomy, 0.25% bupivacaine was applied on the surgical area; Group 3 (subcutaneous infiltration with bupivacaine): following thyroidectomy, 0.25% bupivacaine was injected into the cutaneous, subcutaneous region and fascia of the surgical area. Postoperative pain was evaluated by a visual analog scale (VAS) at 1(st), 4(th), and 12(th) hours after thyroidectomy. Total daily requirement for additional analgesia was recorded. RESULTS The mean age of 90 patients was 44.37±13.42 years, and the female:male ratio was 62:28. There was no difference between study groups in terms of age, thyroid volume, TSH and T4 levels. VAS score of patients in paratracheal infiltration with bupivacaine group was significantly lower than control group patients at 1(st), 4(th) and 12(th) hours following thyroidectomy (p=0.030, p=0.033, p=0.039, respectively). The need for analgesics was significantly lower in both paratracheal infiltration and subcutaneous infiltration groups than the control group (86.7%, 83.0%, and 73.3%, respectively, p=0.049). CONCLUSIONS Intraoperative local bupivacaine application is effective in decreasing postoperative pain in patients with thyroidectomy.

The purpose of this paper was to analyze the effect of Valsalva maneuver application before finalizing thyroidectomy operations on the identification of bleeding points and postoperational drainage. One hundred patients (age range, 24-76 years) with multinodular goiter, recurrent multinodular goiter, toxic diffuse multinodular goiter, or papillary thyroid cancer were included in the study and were divided into 2 groups of 50 randomly. Both groups underwent thyroidectomy operation, only 1 group received intraoperative Valsalva maneuver application (twice, 30 seconds of 30-cm PEEP). The size of the thyroid gland, the duration of operation, hospital stay, and drain usage were reported. Postoperational occurrences of drainage, hematoma, reoperation, and additional complications were compared between the groups. Valsalva maneuver application helped to identify minor bleeding points in 32% of the cases. There was no significant difference between the study groups regarding the thyroid gland size, operation duration, hospital stay, and the duration of drain usage (P > 0.05 for all). The amount of drainage as well as the frequencies of hematoma, reoperation, and further complications was not significantly different between the study groups (P > 0.05 for all). Intraoperative application of Valsalva maneuver is only useful to detect minor bleeding points in some patients during thyroidectomy operations, but it had no effect on the duration of postoperative drain usage, the amount of drainage, and risk of hematoma. Therefore, intraoperative application of Valsalva maneuver has no beneficial effect on postoperative hemorrhagic complication after thyroidectomy operations.

Objectives: Pycnogenol® (PYC®), a standardized extract from the bark of Pinus maritima, consists of different phenolic compounds. PYC® has shown to have protective effects on chronic diseases such as diabetes, asthma, cancer, and immune disorders. The aim of this study was to determine the effects of PYC® against the DNA damage and biochemical changes in blood, liver, and lung tissues of ischemia-reperfusion (IR)-induced Wistar albino rats. Materials and Methods: A sham group, IR injury-induced group, and IR+PYC® group were formed. Ischemia was induced and sustained for 45 min, then the ischemic liver was reperfused, which was sustained for a further 120 min at the end of this period. After anesthesia and before the IR inducement, 100 mg/kg PYC® was given to the IR+PYC® group through intraperitoneal injections. The total oxidant (TOS) and total antioxidant status (TAS), total thiol levels (TTL), advanced oxidation protein products (AOPP), and biochemical parameters [myeloperoxidase (MPO), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH)] in the rats were analyzed using spectrophotometric methods and DNA damage was assessed using single-cell gel electrophoresis. Results: The levels of TOS, TTL, MPO, AOPP, ALT, AST, and LDH were significantly decreased in the IR+PYC® group compared with the IR group (p<0.05). The levels of TAS were significantly increased in the IR+PYC® group compared with the IR group (p<0.05). PYC® reduced the DNA damage when compared with the IR group (p<0.05). Conclusion: The present results suggest that PYC® treatment might have a role in the prevention of IR-induced oxidative damage by decreasing DNA damage and increasing antioxidant status.

Recently Unusual Surgical Educational Case : A Real Giant Nodular Goiter

Mehmet Kılıç; Murat Baki Yıldırım; Doğukan Durak; Ersin Gürkan Dumlu; Abdussamed Yalcin

Normal thyroid tissue has a homogeneous structure, but sometimes thyroid tissue may show nodule formation. These nodules may occur with follicles junction that is full of colloid or they may occur with less adenoma or cysts. A 5% nodular goiter incidence is seen at nonendemic regions and 15% at endemic regions (1). Nodules, which are larger than 1 cm, can only be realized with palpation at physical examination. Although these nodules are asymptomatic, they may cause symptoms when their sizes become larger. So, for the training purpose, this study aims to study a real huge nodular goiter incidence case that is rarely seen nowadays.
