Incidental gastric glomus tumor after laparoscopic sleeve gastrectomy
Gastric glomus tumors (GGTs) are unusual benign, subepithelial, mesenchymal neoplasms of modified smooth muscle cells representing a neoplastic counterpart of glomus bodies. A 38-year-old woman was admitted to our clinic presenting morbid obesity. Routine preoperative evaluations, such as laboratory analysis, abdominal ultrasonography, and upper gastrointestinal endoscopy, were performed. She underwent a classical laparoscopic sleeve gastrectomy (LSG). The postoperative course was uneventful and she was discharged for outpatient control. Her histopathology report revealed a GGT 0.8 cm in diameter. No further treatment was done and she had lost 28 kg at the postoperative sixth month. Here, we present the case of GGT, which was diagnosed incidentally after LS

CLINICAL IMPORTANCE OF SOLITARY SOLID NODULE OF THE THYROID IN ENDEMIC GOITER REGION
Context: Endemic area and iodine supplementation may affect the
pathogenesis of the nodule which commonly occurs in endemic thyroid
enlargement due to iodine deficiency. Aims: To establish pathological
changes in solitary solid and larger nodule of the thyroid in endemic
area. Setting and Design: Retrospective study in Surgical Department
of University Hospital. Methods and Material: We determined 44
surgically treated patients with solitary solid nodule in endemic
goiter area in which the population routinely receives iodinated salt.
The thyroid nodule was preoperatively evaluated with blood chemistry,
ultrasound, nuclear scanning and FNAC. The results of preoperative
evaluation, surgical interventions, and histopathological examination
were analyzed. Statistical analysis: Student t test and
Fisher′s exact test. Results: Twenty (45%;20/44) patients with
hot (autonomous) nodule have received the diagnosis of toxic adenoma.
Twenty four patients had solitary solid and cold nodule. Total
thyroidectomy was performed on two patients with papillary cancer (PTC)
diagnosed by FNAC from cold nodules. Forty two patients have been
treated with total excision of the lobe including hyper or hypoactive
solitary solid nodule. Pathological examination has reported two more
cases of PTC and one case of insular cancer arising from cold nodules.
Completion thyroidectomy was performed on these 3 patients.
Conclusions: Solitary solid and large nodule is a common indication
for thyroid surgery in endemic goiter area. High incidence of
hyperthyroidism due to single autonomous nodule, and high rate of
malignant change (mainly papillary cancer) in solitary hypoactive
nodule arises from this series in endemic thyroid enlargement
Bir akt ileus olgusunda apendiko-ileal fistül
Appendiko-ileal fistül akut ileus tablosu ile nadir görülür. Bu yazıda mekanik barsak tıkanıklığı nedeni ile laparatomi uygulanan apendikoileal fistüllü 46 yaşında erkek olgu sunuldu. Cerrahi sırasında apendiks lümeni ile terminal ileum arasında bir fistül olduğu gözlendi. Ayrıca proksimal ileal ve jejunal ansların gergin olduğu da saptandı. Apendektomi, segmental ileum rezeksiyonu ve uçuca anastomoz cerrahi işlem olarak uygulandı. İnce barsak tıkanıklığı ile akut ileus tablosu gelişen hastalarda, apendiko-ileal fistülün akılda bulunması gerektiğini düşünmekteyiz.Appendico-ileal fistula is a rare condition with acute ileus. We report a case of appendico-ileal fistule in a 46-year-old man patient who has undergone laparatomy for intestinal mechanical obstruction. Intraoperatively, an appendix with a lumen was found with a fistula to the terminal ileum. It has been observed that proximal ileal and jejunal intestinal anses were distended. Appendectomy, segmental ileum resection and end-to-end anastomoses were performed as a surgical procedure. This case describes an elderly man with acute ileus presenting with small bowel obstruction. We conclude that, appendico-ileal fistula should be kept in mind in cases with acute ileus presenting with small bowel obstruction

Ameliyat sonrasi karin içi yapişiklik oluşumunda ba?irsak kan akimindaki de?işiklikler ve endotelin-1 blo?unun rolü
PubMed ID: 16676248BACKGROUND: The current study was planned to investigate intestinal blood flow alterations and the role of ET-1 receptor blockade in the formation of postoperative intraperitoneal adhesion formation. METHODS: Twenty-eight adult Wistar Albino rats weighing between 250 g and 300 g were divided into four groups. Control group (group 1; n=7) did not undergo any operation. Sham group (group 2; n=7) had only laparotomy. In the adhesion group (group 3; n=7), peritoneal patch (1x1 cm) excision from the right abdominal wall and cecal abrasion were done as "adhesion model operation". One week following this, treatment group (group 4; n=7) received a non-selective ET-1 receptor blocking agent bosentan (30 mg/kg, IP) intra-abdominally, once a day for four days. Intestinal blood flow through the superior mesenteric artery was measured, on postoperative seventh day. Adhesion severity and extension as well as myeloperoxidase activity in the adhesion were calculated. RESULTS: Mean intestinal blood flow significantly increased in adhesion group (81.9±5.6 ml/100 g) when compared to group 1 (65.5±1.2 ml/100 g). Bosentan caused a significant decrease (44.3±6.9 ml/100 g) in intestinal blood flow when compared to group 1 and group 2. Sham group (62.2±1 ml/100 g) had similar blood flow level with the control group (65.5±1.2 ml/100g). Adhesion scores were similar in adhesion and Bosentan groups. Sham group had almost no adhesions. Myeloperoxidase activity in adhesion tissue was significantly higher in bosentan group. CONCLUSION: Non-selective ET-1 receptor blockade has no effect on prevention of the formation of intra-abdominal adhesion, but causes a decrease in intestinal blood flow. Adhesion formation increases intestinal blood flow. Adhesion formation is accompanied by increased polymorphonuclear infiltration despite bosentan treatment
Kolonik anastomoz düzeylerinin sivi faz mide boşalma hizina etkileri
The aim of this study was to investigate the effect of colonic anastomoses at different levels on liquid phase gastric emptying rate. Initiation of oral feeding after colorectal surgical procedures depends on the beginning of bowel movements. We hypothesize that surgical procedures which are performed at different colonic levels, may affect gastric motility and may alter the oral feeding starting time. Liquid phase gastric emptying rates of 49 adult male Wistar Albino rats were measured with methyl cellulose phenol red test. Two groups of 14 rats underwent ascending colon or colorectal anastomosis. We also studied a sham-op group (n=14) with laparotomy only and a control group (n=7) with no surgery. Half of each group underwent gastric emptying test on postoperative first (n=7) or tenth (n=7) days. The gastric emptying rates on the first postoperative day were (34.9±1.5%), (50.9±5.2%), and (58.3±4.5%) in colorectal anastomosis, ascending colon anastomosis, and sham-op groups, respectively. While gastric emptying rates returned to the control group levels (71.5±5.7%) on postoperative tenth day, in ascending colon anastomosis (72.5±2.1%) group and sham-op (69±1.8) group, it was still significantly lower in colorectal anastomosis (49.9±7.8%) group compared to the control group level. This study shows that colorectal anastomosis causes a delay in liquid phase gastric emptying rate compared to ascending colon anastomosis. Our findings also imply that the influence of colonic anastomosis on gastric emptying rate appears to be related to the site of colonic anastomosis
