Efficacy of ultrasonography in identification of non-recurrent laryngeal nerve

BACKGROUND The aim of this prospective study was to identify the arterial anomalies constantly associated with nonrecurrent inferior laryngeal nerve by preoperative ultrasonography and impact on recurrent inferior laryngeal nerve palsy (RILN). METHOD The study included 332 patients who underwent thyroidectomy or parathyroidectomy between 2009 February and 2011 October. Preoperative ultrasonography was performed to all patients to identify vascular anomalies related to NRILN. CT was performed only in patients with NRILN predicted with preoperative ultrasonography. Systematic nerve dissection was performed surgically. Patient characteristics, type of NRILN, preoperative and postoperative vocal cord mobility and morbidity were recorded. RESULTS The NRILN was identified in 6 patients on the right side (1.94%). Preoperative ultrasonography predicted NRILN in all cases (accuracy 100%). CONCLUSION Ultrasonography is a very reliable and simple method to be used in preoperative assessment to identify vascular anomaly associated with NRILN to make optimal surgical decisions against nerve damage in patients undergoing thyroidectomy or parathyroidectomy. Adequate surgical technique is of great importance.

The efficacy of the semi-blind approach of transversus abdominis plane block on postoperative analgesia in patients undergoing inguinal hernia repair: a prospective randomized double-blind study

Purpose In this prospective, randomized, double-blind study, our aim was to compare the analgesic efficacy of the semi-blind approach of transversus abdominis plane (TAP) block with a placebo block in patients undergoing unilateral inguinal hernia repair. Methods After receiving hospital ethical committee approval and informed patient consents, American Society of Anesthesiologists (ASA) I–III patients aged 18–80 were enrolled in the study. Standard anesthesia monitoring was applied to all patients. After premedication, spinal anesthesia was administered to all patients with 3.5 mL heavy bupivacaine at the L3-L4 subarachnoid space. Patients were randomly allocated into 2 groups. Group I (n = 32) received a placebo block with 20 mL saline, Group II (n = 32) received semi-blind TAP block with 0.25% bupivacaine in 20 mL with a blunt regional anesthesia needle into the neurofascial plane via the lumbar triangle of Petit near the midaxillary line before fascial closure. At the end of the operation, intravenous (IV) dexketoprofen was given to all patients. The verbal analog scale (VAS) was recorded at 2, 4, 6, 12, and 24 hours postoperatively. Paracetamol IV was given to patients if their VAS score > 3. A rescue analgesic of 0.05 mg/kg morphine IV was applied if VA S > 3. Total analgesic consumption and morphine requirement in 24 hours were recorded. Results TAP block reduced VAS scores at all postoperative time points (P < 0.001). Postoperative analgesic and morphine requirement in 24 hours was significantly lower in group II (P < 0.01). Conclusion Semi-blind TAP block provided effective analgesia, reducing total 24-hour postoperative analgesic consumption and morphine requirement in patients undergoing elective unilateral inguinal hernia repair.

Early versus delayed laparoscopic cholecystectomy for acute cholecystitis: a prospective, randomized study.

We aimed to compare the clinical outcome and cost of early versus delayed laparoscopic cholecystectomy for acute cholecystitis. Sixty patients with acute cholecystitis were randomized into early (within 24 hours of admission) or delayed (after 6-8 weeks of conservative treatment) laparoscopic cholecystectomy groups. There was no significant difference between study groups in terms of operation time and rates for conversion to open cholecystectomy. On the other hand, total hospital stay was longer (5.2 ± 1.40 versus 7.8 ± 1.65 days; P = 0.04) and total costs were higher (2500.97 ± 755.265 versus 3713.47 ± 517.331 Turkish Lira; P = 0.03) in the delayed laparoscopic cholecystectomy group. Intraoperative and postoperative complications were recorded in 8 patients in the early laparoscopic cholecystectomy group, whereas no complications occurred in the delayed laparoscopic cholecystectomy group (P = 0.002). Despite intraoperative and postoperative complications being associated more with early laparoscopic cholecystectomy compared with delayed intervention, early laparoscopic cholecystectomy should be preferred for treatment of acute cholecystitis because of its advantages of shorter hospital stay and lower cost.

Management of fistula of ileal conduit in open abdomen by intra-condoit negative pressure system

INTRODUCTION We aimed to present the management of a patient with fistula of ileal conduit in open abdomen by intra-condoid negative pressure in conjunction with VAC Therapy and dynamic wound closure system (ABRA). PRESENTATION OF CASE 65-Year old man with bladder cancer underwent radical cystectomy and ileal conduit operation. Fistula from uretero-ileostomy anastomosis and ileus occurred. The APACHE II score was 23, Mannheim peritoneal index score was 38 and Björck score was 3. The patient was referred to our clinic with ileus, open abdomen and fistula of ileal conduit. Patient was treated with intra-conduid negative pressure, abdominal VAC therapy and ABRA. DISCUSSION Management of urine fistula like EAF in the OA may be extremely challenging. Especially three different treatment modalities of EAF are established in recent literature. They are isolation of the enteric effluent from OA, sealing of EAF with fibrin glue or skin flep and resection of intestine including EAF and re-anastomosis. None of these systems were convenient to our case, since urinary fistula was deeply situated in this patient with generalized peritonitis and ileus. CONCLUSION Application of intra-conduid negative pressure in conjunction with VAC therapy and ABRA is life saving strategies to manage open abdomen with fistula of ileal conduit.

Intrarectal negative pressure system in the management of open abdomen with colorectal fistula: A case report

INTRODUCTION To present the management of open abdomen with colorectal fistula by application of intrarectal negative pressure system (NPS) in addition to abdominal NPS. PRESENTATION OF CASE Twenty-year old man had a history of injuries by a close-range gunshot to the abdomen eight days ago and he had been treated by bowel repairs, resections, jejunal anastomosis and Hartmans procedure. He was referred to our center after deterioration, evisceration with open abdomen and enteric fistula in septic shock. There were edematous, fibrinous bowels and large multiple fistulas from the edematous rectal stump. APACHE II, Mannheim Peritoneal Index and Björck scores were 18, 33 and 3, respectively (expected mortality 100%). After intensive care for 5 days, he was treated by abdominal and intrarectal NPS. NPS repeated for 5 times and the fistula was recovered on day 18 completely. Fascial closure was facilitated with a dynamic abdominal closure system (ABRA) and he was discharged on day 33 uneventfully. There was no herniation and any other problem after 12 months follow-up. DISCUSSION Management of fistula in OA can be extremely challenging. Floating stoma, fistula VAC, nipple VAC, ring and silo VAC, fistula intubation systems are used for isolation of the enteric effluent from OA. Several biologic dressings such as acellular dermal matrix, pedicled flaps have been used to seal the fistula opening with various success. Resection of the involved enteric loop and a new anastomosis of the intestine is very hard and rarely possible. In all of these reports, usually patients are left to heal with a giant hernia. In contrast to this, there is no hernia in our case during one year follow up period. CONCLUSION Combination of intra and extra luminal negative pressure systems and ABRA is a safe and successful method to manage open abdomen with colorectal fistula.

The effect of laparoscopic sleeve gastrectomy on morbid obesity and obesity-related comorbidities: A cohort study

OBJECTIVE Bariatric surgery with multidisciplinary management is a more effective method to treat morbid obesity and obesity-related comorbidities compared with nonsurgical treatments. Laparoscopic sleeve gastrectomy (LSG) was initially performed as the first stage of biliopancreatic diversion with duodenal switch in the super-obese population. In the past few years, however, LSG has been performed as a definitive procedure because of its promising early and midterm results. The aim of this study is to evaluate the efficacy of our initial LSG series of 73 patients on excess weight loss (EWL) and resolution of obesity-related comorbidities in short-term follow-up. MATERIAL AND METHODS From March 2013 to May 2014, 78 morbid obese patients with an average body mass index (BMI) of 46.3 kg/m(2) underwent LSG. There is a 9-month follow-up period on average. Five patients were excluded from the study, because they could not be contacted. Comorbidities, preintervention BMI, glucose, HbA1c, and lipid profiles were recorded at 1, 6, and 12 months postintervention. RESULTS After the surgery, the percent EWL was 58%. The mean serum glucose level, HbA1c level, LDL-cholesterol level, triglyceride level, insulin, and insulin resistance decreased significantly and the mean HDL-cholesterol level increased. CONCLUSION For the resolution of comorbidities, LSG may be used as an effective bariatric and metabolic surgery.

Prophylactic Ozone Administration Reduces Intestinal Mucosa Injury Induced by Intestinal Ischemia-Reperfusion in the Rat.

Objectives. Intestinal ischemia-reperfusion injury is associated with mucosal damage and has a high rate of mortality. Various beneficial effects of ozone have been shown. The aim of the present study was to show the effects of ozone in ischemia reperfusion model in intestine. Material and Method. Twenty eight Wistar rats were randomized into four groups with seven rats in each group. Control group was administered serum physiologic (SF) intraperitoneally (ip) for five days. Ozone group was administered 1 mg/kg ozone ip for five days. Ischemia Reperfusion (IR) group underwent superior mesenteric artery occlusion for one hour and then reperfusion for two hours. Ozone + IR group was administered 1 mg/kg ozone ip for five days and at sixth day IR model was applied. Rats were anesthetized with ketamine∖xyzlazine and their intracardiac blood was drawn completely and they were sacrificed. Intestinal tissue samples were examined under light microscope. Levels of superoxide dismutase (SOD), catalase (CAT), glutathioneperoxidase (GSH-Px), malondyaldehide (MDA), and protein carbonyl (PCO) were analyzed in tissue samples. Total oxidant status (TOS), and total antioxidant capacity (TAC) were analyzed in blood samples. Data were evaluated statistically by Kruskal Wallis test. Results. In the ozone administered group, degree of intestinal injury was not different from the control group. IR caused an increase in intestinal injury score. The intestinal epithelium maintained its integrity and decrease in intestinal injury score was detected in Ozone + IR group. SOD, GSH-Px, and CAT values were high in ozone group and low in IR. TOS parameter was highest in the IR group and the TAC parameter was highest in the ozone group and lowest in the IR group. Conclusion. In the present study, IR model caused an increase in intestinal injury.In the present study, ozone administration had an effect improving IR associated tissue injury. In the present study, ozone therapy prevented intestine from ischemia reperfusion injury. It is thought that the therapeutic effect of ozone is associated with increase in antioxidant enzymes and protection of cells from oxidation and inflammation.

Cholesterolosis in routine histopathological examination after cholecystectomy: What should a surgeon behold in the reports?

INTRODUCTION Cholecystectomy is one of the most common surgical procedures. Postoperative investigation of cholecystectomy specimen has a great value since histopathological reports may document some entities with significant clinical consequences. The aim of this study was to evaluate the association between cholesterolosis and the reports indicating some histopathological alterations in symptomatic cholecystitis. METHODS This paper is based on a retrospective study. Histopathological reports of 432 cholecystectomy specimens between January 2011 and June 2013 were reviewed. Three reports were excluded due to perioperative diagnosis of cancer. Reports of 429 cholecystectomy specimens of the acute and symptomatic chronic cholecystitis patients were analyzed. Standardization of the reporting was questioned. Age, gender, histopathological wall thickness of gallbladder, reporting rates of acute inflammation, cholesterolosis, polypoid lesions, epithelial hyperplasia, gastric or intestinal metaplasia, dysplasia and incidental cancer were investigated and compared between patients with and without cholesterolosis. Reported rates of histopathological findings were comparable between patients under and over 60 years old and patients with and without reported cholesterolosis. RESULTS Reported histopathological findings were presented as acute inflammation in 46 (10.7%), cholesterolosis in 79 (18.4%), gallbladder polypoid lesions in 7 (1.6%), epithelial hyperplasia in 16 (3.7%), metaplasia of any type in 34 (7.9%) of 429 patients. Dysplasia was excluded whereas one incidental gallbladder carcinoma was reported. Epithelial hyperplasia and metaplasia were found to be related to age. Gallbladder wall thickness was decreased with cholesterolosis. However, only a correlation between cholesterolosis and gender or metaplasia was noted. CONCLUSION Recent study suggests that cholesterolosis is somehow associated with metaplasia. Thus, surgeons should carefully interpret the histopathology reports based on unusual or exceptional findings corresponding to the cholecystectomy specimens. Any abnormal finding in the reports should be investigated in terms of the progress of the pathology and also its clinical consequences.

Replacement of Vena Cava up to the Right Atrium during Living Donor Liver Transplantation for Echinococcus alveolaris

Management of advanced stage of Echinococcus alveolaris is a very difficult procedure. Surgical treatment like resection and liver transplantation is accepted procedure nowadays. Here we presented a case report of Echinococcus alveolaris which invaded the inferior vena cava up to the right atrium and surrounding tissues. This patient underwent living donor liver transplantation with replacement of inferior vena cava up to the right atrium with cryopreserved cadaveric aortic graft. This procedure is very difficult but it is a life-saving chance for patients in advanced cases of Echinococcus alveolaris.

Non-recurrent laryngeal nerve

Injury to the recurrent laryngeal nerve is a serious complication in thyroid and parathyroid surgery. The anatomy of the recurrent laryngeal nerve is variable. Non-recurrent nerve is a very rare variation of the inferior laryngeal nerve. Because of the anatomical variations of the nerve, preservation of the nerve is the optimal strategy during surgery. In this case report, we present a non-recurrent laryngeal nerve abnormality in a patient who underwent parathyroidectomy, thyroidectomy and functional neck dissection for malignant parathyroid disease. A non-recurrent laryngeal nerve was identified during nerve exploration.
