The association of obesity with atrial fibrillation (AF) and with ventricular arrhythmias is well documented. The aim of this study was to investigate whether weight reduction by a laparoscopic sleeve gastrectomy has any effect on P wave dispersion (PWD), a predictor of AF, and corrected QT interval dispersion (CQTD), a marker of ventricular arrhythmias, in obese individuals. In a prospective study, a total of 114 patients (79 females, 35 males) who underwent laparoscopic sleeve gastrectomy were examined. The patients were followed 1 year. PWD and CQTD values before and 3rd, 6th, and 12th months after the surgery were calculated and compared. There was a statistically significant decline in body mass index (BMI), PWD, and CQTD values among baseline, 3rd, 6th, and 12th months (p < 0.001 for all comparisons). Correlation analysis showed a statistically significant correlation between Delta PWD and Delta BMI (r = 0.719, p < 0.001), Delta PWD and Delta left ventricular end-diastolic diameter (LVEDD) (r = 0.291, p = 0.002), Delta PWD and Delta left atrial diameter (LAD) (r = 0.65, p < 0.001), Delta CQTD and Delta BMI (r = 0.266, p = 0.004), Delta CQTD and Delta LVEDD (r = 0.35, p < 0.001), Delta CQTD and Delta LAD (r = 0.289, p = 0.002). In multiple linear regression analysis, there was a statistically significant relationship between Delta PWD and Delta BMI (beta = 0.713, p < 0.001), Delta PWD and Delta LVEDD (beta = 0.174, p = 0.016), Delta PWD and Delta LAD (beta = 0.619, p < 0.001), Delta CQTD and Delta BMI (beta = 0.247, p = 0.011), Delta CQTD and Delta LVEDD (beta = 0.304, p < 0.001), Delta CQTD and Delta LAD (beta = 0.235, p = 0.009). PWD and CQTD values of patients were shown to be attenuated after bariatric surgery. These results indirectly offer that there may be a reduction in risk of AF, ventricular arrhythmia, and sudden cardiac death after obesity surgery.
Isolated jejunal metastasis in a patient with cervical cancer: A case report
(2015) Onal, Cem; Nursal, Gul Nihal; Torer, Nurkan; Kayaselcuk, Fazilet; 25949229
Background: In approximately 8% of cervical carcinoma patients, gastrointestinal tract is involved, most commonly the rectosigmoid portion, because of local extension. Isolated metastases to small bowel are exceedingly rare. Case report: We present a case of a 63-year-old woman with cervical cancer who developed isolated jejunal metastasis 8 months after postoperative chemoradiotherapy. The patient was alive with no evidence of disease 6 months after resection of metastasis. Very few cases have been reported concerning squamous cell carcinoma of the cervix with documented metastases to the small bowel. There is only one published case report of cervical cancer with multiple metastases to the small intestine and jejunum. To our knowledge, this is the first case of cervical cancer with isolated jejunal metastasis, which was initially demonstrated with positron emission tomography and confirmed histopathologically. Conclusion: Although the exact mechanism underlying the isolated metastasis is unknown, hematogenous spread or tumor seeding during surgery may play a role. (C) 2015 Greater Poland Cancer Centre.

Laparoscopic Repair of Morgagni Hernia
(2015) Arer, Ilker Murat; Yabanoglu, Hakan; Aytac, Huseyin Ozgur; Caliskan, Kenan; Torer, Nurkan
Morgagni hernia is a congenital herniation of abdominal contents into the thoracic cavity through a retrosternal diaphragmatic defect and make up about 1 % - 5 % of all types of congenital diaphragmatic hernias. Surgical repair of Morgagni hernias is usually indicated when patients are symptomatic and have a high risk of strangulation or incarceration of the contained viscera. 71-year-old male patient admitted to emergency department with a 2-day history of abdominal pain, vomiting and obstipation. Laparoscopic repair for Morgagni hernia was performed. Laparoscopic repair for Morgagni hernia with mesh repair is secure, satisfactory and easily performed.
Morbidity and Mortality of Colorectal Cancer Surgery in Octogenarians
(2016) Torer, Nurkan
Objectives The aim of this study was to determine common problems, preoperative assessment criteria, and postoperative morbidity and mortality of octogenarians with colorectal cancer. Materials and method We screened the medical records of patients aged 80 years or older (study group) and that of patients of 50-59 years of age (control group) who were operated for colon cancer. Demographic features, comorbidities, American Society of Anaesthesiologists (ASA) score, urgency of operation, tumor localization, presence of colostomy, duration of hospital stay, admission to and duration of stay in the intensive care unit (ICU), TNM (Tumor, Node, Metastasis) stage, postoperative morbidity, and mortality rates were recorded. Results The medical records of 23 patients aged above 80 years and 39 patients aged between 50-59 years were screened retrospectively. The two groups did not differ significantly with respect to the morbidity rate but the mortality rate was significantly higher in the study group (p = 0.583 and p = 0.016, respectively). The study group patients needed significantly more ostomy creation procedures. In the analysis of the octogenarian groups, the ASA score or the presence of comorbidities had no discernible effect on the morbidity and mortality rates. Conclusion Specific preoperative evaluations are needed for prediction of mortality risk in geriatric patients. Rational criteria for performing protective ostomy should also be determined in octogenarians.
Organ Sparing Surgery for a Giant Liposarcoma
(2015) Aytac, Huseyin Ozgur; Torer, Nurkan; Ozen, Merve; Arer, Ilker Murat
Liposarcomas those are malignant soft tissue tumors often occur in large sizes in the retroperitoneum and abdomen due to their silent clinic. Excision with negative margins is the gold standard of treatment. A case operated on for a giant intraabdominal liposarcoma is being reported. A giant soft tissue tumor filling the whole abdomen was determined in the computed tomography scan. Core biopsy was obtained and demonstrated a well-differentiated liposarcoma. A 15 kg of mass 44x30x14 cm in size was excised en-bloc. Pathological examination of this tumor showed a well-differentiated liposarcoma with mixoid parts. No recurrence was observed in two years of follow-up despite any adjuvant therapy. This is to be one of the largest retroperitoneal sarcomas in the literature.

The Type of Specimen Retrieval in Laparoscopic Appendectomy Affects Wound Infection
(2016) Aytac, Huseyin Ozgur; Torer, Nurkan; Arer, Ilker Murat; 0000-0002-3583-9282; 28070028; AAJ-7913-2021
AIM: To evaluate the role of laparoscopy in appendicitis and importance of wound protection in this sense. MATERIALS AND METHODS: Data of 506 patients operated on by either open or laparoscopic appendectomy within the last four years were evaluated retrospectively for wound infection rates. Those had laparoscopic surgery were also sub grouped and analyzed in terms of retrieval type of the specimen. RESULTS: Wound infection rate was 5.7% for open appendectomy and zero for laparoscopic appendectomy in minimal or non-inflamed cases. For suppurative appendicitis and gangrenous or perforated cases wound infection rates were 9.1% versus 17.6% for open appendectomy versus laparoscopy. Laparoscopy without wound protection increased these rates to 17.9% versus 50%, where as wound protection reduced both to zero. DISCUSSION: Laparoscopy itself was protective for wound infection in non-inflamed or minimally inflamed appendectomy cases with respect to open surgery. However, for suppurative, gangrenous or perforated appendicitis, laparoscopy protects from wound infection only when contact of the specimen with incisions was avoided. CONCLUSION: Laparoscopy reduces wound infection rates in appendectomy. This advantage is prominent especially wound contamination with the specimen is prevented anywise. Using a glove finger, as a tissue bag for the retrieval of the specimen has been our favorite method that we defined as "reverse cover-up technique".
