The diagnosis of GM should be made carefully to avoid a misdiagnosis. Steroid therapy should be considered based on the idea that this is an autoimmune disease.
iPTH(15) value and iPTH(%) rate accurately predicts the completeness of resection in secondary hyperparathyroidism. The rate of decrease in serum iPTH detected intraoperatively compared to preoperative baseline levels exceeding 90% in sPx, 95% in tPx, accurately predicts the success of surgery. Postoperative normocalcemia without calcium replacement would raise a suspicion about completeness of surgical resection.
Intact parathormone measurement 10 min after SC is helpful to predict early postoperative hypocalcemia. An IPTH decrease >/=30% at this time point estimates the risk of postoperative hypocalcemia.
We suggest that this surgical procedure may successfully be applied to a large majority of the patients. It does not lead to unnecessary excision of healthy tissue because of its significantly simpler nature compared with the full-layer flap technique and its S-type incision, it does not create a midline scar tissue, and it is able to flatten the gluteal sulcus.
Providing neodjuvant treatment and preserving at least half of the functional internal anal sphincter mass produces acceptable oncological and functional outcomes in patients undergoing intersphincteric rectal resection for very low rectal cancer. However, whether smooth muscle plasty further improves postoperative continence should be tested by further studies.
Diagnosis of pancreatitis is based on the determination of serum amylase and lipase levels. However, recent identification of specific leptin receptors in the pancreas suggests that this peptide may also play some roles in the modulation of pancreatic function. The objective of the present study was to investigate the relationship between serum leptin levels and pancreatitis. Thirty male Wistar rats were divided into 3 groups: the control group, acute pancreatitis group and chronic pancreatitis group. Pancreatitis was induced by injection of ethyl alcohol into the common biliary duct. A sham laparotomy was performed in the control group. Control and acute pancreatitis groups were sacrificed 24 hours later, and chronic pancreatitis group was sacrificed on postoperative day 7. Blood was taken by cardiac puncture for the determination of plasma leptin levels, and the pancreatic tissue was excised for histopathologic confirmation of pancreatitis. Plasma leptin rose significantly from the median of 0.78 ± 0.12 ng/ml in the control group to 1.92 ± 0.10 ng/ml and 1.86 ± 0.13 ng/ml in acute and chronic pancreatitis groups, respectively (p < 0.001, for both). There was no significant difference in the plasma leptin levels between the acute pancreatitis group and the chronic pancreatitis group (p > 0.05). These findings confirm that leptin has a role in pancreas inflammation, and the inflamed tissue can be the source of local production of leptin.leptin; acute pancreatitis; chronic pancreatitis
AIM:To determine the effect of chemotherapy on wound healing by giving early preoperative 5-fluorouracil (5-FU) to rats with colonic anastomoses.
METHODS:Sixty Albino-Wistar male rats (median weight, 235 g) were used in this study. The rats were fed with standard laboratory food and given tap water ad libitum . The animals were divided into three groups:Group 1: Control group (chemotherapy was not administered), Group 2: Intraperitoneally (IP) administered 5-FU group (chemotherapy was administered IP to animals at a dose of 20 mg/kg daily during the 5 d preceeding surgery), Group 3: Intravenously (IV) administered 5-FU group. Chemotherapy was administered via the penil vein, using the same dosing scheme and duration as the second group. After a 3-d rest to minimize the side effects of chemotherapy, both groups underwent surgery. One centimeter of colon was resected 2 cm proximally from the peritoneal reflection, then sutured intermittently and subsequently end-to-end anastomosed. In each group, half the animals were given anaesthesia on the 3rd postoperative (PO) day and the other half on the 7th PO day, for in vivo analytic procedures. The abdominal incisions in the rats were dissected, all the new and old anastomotic segments were clearly seen and bursting pressures of each anastomotic segment, tissue hydroxyproline levels and DNA content were determined to assess the histologic tissue repair process.
RESULTS:When the IV group was compared with the IP group, bursting pressures of the anastomotic segments on the 3rd and 7th PO days, were found to be significantly decreased, hydroxyproline levels at the anastomotic segment on the 7th PO day were significantly decreased (P < 0.01).
CONCLUSION:In this study, we conclude that early preoperative 5-FU, administered IV, negatively affects wound healing. However, IP administered 5-FU does not negatively affect wound healing.
Purpose: Aim of this study was to report our experience in elective and emergency surgery on chronic hemodialysis (CH) patients for end-stage renal disease (ESRD). Methods: All patients on CH for ESRD who underwent various surgical procedures in our unit within the past 9-year period (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) were included in this study. These patients were divided into two groups according to the type of surgery performed: elective or emergency. Demographic data, indications for surgery, primary causes of ESRD, surgical procedures, postoperative complications, and mortality rates were studied. Results: Of 130 patients, 121 underwent elective surgery while 10 were addressed for emergency operation. In the elective surgery group, the most common diseases were secondary hyperparathyroidism, kidney diseases, cholelithiasis, and diabetic foot gangrene. Complications occurred in nine patients (morbidity rate, 7%) and only one patient died (mortality rate, 0.8%). In the emergency surgery group, the most common diseases were diabetic foot gangrene and obstructed sigmoid colon cancer. In this group, complications occurred in seven patients (total morbidity rate, 70%) and two patients died (mortality rate, 20%). Conclusions: Elective surgery in patients on CH for ESRD can be performed with acceptable surgical risks provided careful preoperative preparation, intraoperative, and postoperative precautions are taken.
