Is ultrasound guidance necessary to avoid complications in the implantation of venous access ports?

BACKGROUND: The aim of this study was to present demographic information of patients undergoing totally implantable venous access port (TIVAP) implantation and to investigate the rates of early and late complications, assessing the benefits of performing the procedure underUS guidance. METHODS: From May 2018 to December 2023, the outcomes of a total of 537 TIVAP implantation procedures were analyzed retrospectively. Data of the surgeons' experiences for both puncture methods (anatomical landmarks and ultrasound guidance) are presented in the study. RESULTS: The average age of the patients was 53.1±11.9 years, and 261 (48.6%) were female. The right subclavian vein was the preferred insertion site. Fourteen patients developed early complications and 11 developed late complications. Arterial puncture was the most common early complication, while catheter-related infection was the most common late complication. The age, sex, and body mass index of the patients were not independent risk factors for developing complications. Early complications increased as the number of puncture attempts did (p=0.034) and developed significantly less when ultrasound guidance was used during insertion (p=0.011). CONCLUSION: The risk of developing complications was not affected by patient's age or sex. In addition, body mass index was not shown to be an independent risk factor for patients developing complications. It may be concluded from the study that early complications in particular can be reduced with ultrasound-guided implantation.

Endovascular and surgical management of splenic artery aneurysms.

BACKGROUND: Although true splenic artery aneurysms (SAA) are rare, due to advancements in imaging techniques, they are seen more frequently. The aim of this study is to present our strategy of managing patients with SAA. METHODS: Retrospectively, 13 patients who were treated in a tertiary university care center between 2012 and 2020 were included. Their demographic, clinical information, and post-operative complications were analyzed. RESULTS: Seven male and six female patients were evaluated between the ages of 27 and 73. The mean age was 49.8±13.2. The diameter of the aneurysm was between 17 and 80 mm with a mean range of 31.5±16 mm. Seven patients were treated with endovascular interventions (EV). Two patients were referred to surgery with failed attempt of EV, but patients refused surgery and were followed up consequently. Patients who had larger aneurysms with an increased risk of rupture underwent aneurysmectomy and splenectomy. Conservative management was decided on two patients initially: A patient who was previously operated on for a sigmoid colon tumor, and had an aneurysm size of 15 mm and another patient with a surgical history of thoracic aortic dissection with an aneurysm size of 18 mm. One patient who underwent surgery had post-operative pancreatic fistula and was treated with percutaneous drainage. The treatment of the remaining 12 patients was completed without any further complications. CONCLUSION: Splenic artery aneurysm treatment should be individualized. Endovascular treatment can be considered for patients with stable aneurysms larger than 2 cm in the elective setting. Open surgical treatment should be considered in patients with ruptured SAA or hemodynamically unstable, complicated patients.

Is the increased ozone dosage key factor for its anti-inflammatory effect in an experimental model of mesenteric ischemia?

BACKGROUND: Ischemia/reperfusion injury of the intestines is a severe surgical condition. This study aimed to reveal ozone therapy effects with relatively increased ozone dosage in a created ischemia/reperfusion injury model. METHODS: In this study, 24 albino Wistar rats were examined in three groups. Rats in the control group (CG, n=8) underwent only a laparotomy. In the sham group (SG, n=8) and ozone group (OG, n=8), the superior mesenteric artery (SMA) of the rats was occluded for 1 h. After deoccluding the SMA, the abdomen was closed, physiological saline was infused intraperitoneally in the SG, and an increased ozone/oxygen mixture dose (from 0.7 mg/kg to 1 mg/kg) was infused intraperitoneally in the OG. Small intestine samples were obtained at the 24th h for histopathological examination of intestinal mucosal injury and evaluated according to the Chiu score. In addition, Malondialdehyde and Myeloperoxidase levels were evaluated for oxidant levels, whereas, Glutathione (GSH) enzyme activity was measured to evaluate the tissue antioxidant system. RESULTS: Histopathologically, the Chiu score was the lowest in the CG. It was lower in the OG compared to the SG showing the ameliorating effect of ozone on the intestinal mucosa. Chiu score in the OG was higher compared to that in the CG, but not statistically significant. A significantly higher GSH level was observed in the OG compared to the SG, proving antioxidant activity. CONCLUSION: In this experimental model of ischemia/reperfusion in rats, treatment with an increased ozone level decreased the inflammatory process through antioxidant mechanisms and reduced intestinal mucosal damage. However, the effectiveness of ozone therapy depends on its dosages.

A rare cause of intestinal obstruction in children: signet-ring cell adenocarcinoma of the colon.

BACKGROUND: Signet-ring cell adenocarcinoma of the colon is well-recognized in adult patients who are extremely rare and not well-documented in children. Our study aims to raise awareness about this rare disease and its long-term outcomes. METHODS: We retrospectively evaluated patients with signet-ring cell colon adenocarcinoma. RESULTS: Six patients, three boys and three girls, with a mean age of 14.83 (range, 13-17 years), presented with signs of intesti-nal obstruction and were diagnosed with signet-ring cell colon adenocarcinoma. All patients had air-fluid levels on abdominal X-ray. Abdominal ultrasonography of all patients revealed subileus. Abdominal computed tomography was performed in five patients, and pre-operative colonoscopy was conducted in two patients before the emergency intervention. All of the patients underwent emergent exploratory laparotomy with the preliminary diagnosis of acute abdomen. In two patients, debulking surgery followed by a stoma was performed. The remaining four patients were treated with anastomosis following intestinal resection. All girls had metastases on the ovary. One of the patients died due to the burden of multiple metastases in the early period, and three died in the sixth post-operative year. We have been following the remaining two patients since then. CONCLUSION: Although signet-ring cell carcinomas (SRCCs) are rare, they should be considered in the differential diagnosis of acute abdomen and intestinal obstruction in pediatric patients. Despite early diagnosis and treatment, SRCC has a poor prognosis in the pediatric population.

Endoscopic pilonidal sinus treatment (EPSIT) versus sinus laser therapy (SiLaT) for sacrococcygeal pilonidal sinus.

Introduction: New surgical treatment methods are being investigated in sacrococcygeal pilonidal sinus disease. Minimal invasive methods such as endoscopic pilonidal sinus treatment (EPSIT) and sinus laser therapy (SiLaT) have promising results and advantages of laparoscopic surgery. Aim: To compare the efficiency and safety of EPSIT with SiLaT. Material and methods: Seventy-three patients with pilonidal sinus who had undergone EPSIT or SiLaT within 2 years were evaluated retrospectively. Data of patients' demographics, complications and postoperative course were collected and compared between the two groups. Results: We analyzed seventy-three patients who underwent EPSIT or SiLaT, with a mean age of 23.4 ±8.4 (12-46) years and body mass index (BMI) of 25.5 ±4.5 (18-38) kg/m2. Among them, 36 patients (26 males, ten females) underwent EPSIT and 37 patients (27 males, ten females) underwent SiLaT. Mean operative time was similar for both groups (32.3 ±14.8 vs. 31.0 ±14.8; p = 0.757). Early complications (minimal bleeding) were recorded in 2 patients in the SiLaT group. The duration of analgesic use was significantly lower in the EPSIT group compared to the SiLaT group (1.3 ±0.5 (1-3) vs. 1.9 ±1.1 (1-5); p = 0.005). The mean postoperative time of total wound healing was similar for both groups: 23.6 ±14.7 (12-90) vs. 25.2 ±14.5 (14-90) days (p = 0.385). There was no significant difference in the average time of return to total daily activity (3.4 ±0.9 (2-5) vs. 3.6 ±1.2 (2-7) days, p = 0.679). There were no significant differences between the groups regarding late postoperative complications (recurrence: 7). Conclusions: Both methods have similar early and late complications. The duration of need for analgesic usage was shorter in EPSIT patients.

Comparison of hyperbaric oxygen and ozone treatment for ischemia/re-perfusion injury in an experimental testicular torsion model.

BACKGROUND: This study aims to compare the effects of medical ozone (MO) therapy and hyperbaric oxygen (HBO) therapy in an experimental testicular torsion model by measuring the oxidant and antioxidant markers and examining the histopathological tissue damage findings. METHODS: Thirty-two Wistar rats are used and are divided into four groups; (1) sham group (SG), (2) only ischemia/reperfusion (I/R) by testicular torsion, (3) HBO administered group, and (4) MO administered group. No torsion was conducted in the SG. In all other groups, rats underwent testicular torsion followed by detorsion to create an I/R model. After I/R, HBO was injected in the HBO group, and in the MO group, intraperitoneal ozone was applied. At the end of 1 week, testicular tissues were obtained for biochemical analyzes and histopathological examinations. Biochemically, malondialdehyde (MDA) levels were measured for oxidant activity, and superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels were measured for antioxidant activity. Furthermore, the testicles were evaluated histopathologically. RESULTS: Both HBO and MO have significantly decreased MDA levels, compared with sham and I/R groups, resulting in decreased oxidation effects. The antioxidant GSH-Px levels in the HBO and MO groups were significantly higher than in the sham and I/R groups. In addition, the antioxidant SOD levels in the HBO group were significantly higher than sham, I/R, and MO groups. Therefore, the antioxidant effect of HBO was observed to be superior to MO, specifically considering SOD levels. Histopathologically, there was no significant difference between the groups (p>0.05). CONCLUSION: The study may extrapolate that both HBO and MO are antioxidant agents that can be used in testicular torsion. HBO treatment might improve the cellular antioxidant capacity due to increased antioxidant marker levels more than MO therapy. However, further studies are needed with a larger sample size.

Femoral artery aneurysm developed on intimal sarcoma: Case report.

Intimal angiosarcoma is a rare vascular malignancy, and diagnosis is very difficult due to nonspecific symptoms. There are controversial points regarding the diagnosis, treatment and follow-up of intimal angiosarcomas. The purpose of this case report was to evaluate the diagnosis and treatment process of a patient diagnosed with femoral artery intimal angiosarcoma. Furthermore, in line with previous studies, it was aimed to illuminate controversial points. A 33-year-old male patient, who had been operated on due to ruptured femoral artery aneurysm, was diagnosed with intimal angiosarcoma with the pathology result. Recurrence was observed during clinical follow-up, and the patient was treated with chemotherapy and radiotherapy. Since there was no response to treatment, the patient underwent aggressive surgery including the surrounding tissues. No recurrence or metastasis was observed in the patient's 10th month follow-up. Although intimal angiosarcoma is rare, it should be considered in differential diagnosis when femoral artery aneurysm is detected. The most important step in treatment is aggressive surgery, but adding chemo-radiotherapy to the treatment should be considered.

Spontaneous transvaginal small bowel evisceration following hysterectomy: a case report.

Transvaginal small bowel evisceration is a rare, life-threatening condition, requiring urgent surgical intervention. In our case, ischemia developed in the intestinal segment with evisceration, with a laceration in the small intestine of the mesentery, and finally, a small bowel resection was required. An 89-year-old woman was brought to the hospital with a sudden onset of abdominal pain, which lasted for 4 hours. Upon the examination, it was found that approximately 50 cm of the small intestine was eviscerated from the vagina, with its mesentery. The intestines were edematous, and also there were signs of ischemia on the mesentery. The patient was urgently transferred to surgery. Functional end-to-end anastomosis was performed, following a 70 cm small bowel resection. The vaginal defect was repaired transvaginally. Transvaginal small bowel evisceration is rarely described in the literature. It is most commonly seen in postmenopausal, elderly women who underwent vaginal surgery before and who have enterocele. The treatment is an emergent surgical approach. Surgical treatment should be based on individual patient. Various surgical techniques have been described for the repair of transvaginal small bowel evisceration, such as vaginal, abdominal, laparoscopic, and combined approaches. Transvaginal small bowel evisceration should be considered in the differential diagnosis of patients with a sudden onset abdominal pain. Patients with an increased risk for transvaginal small bowel evisceration are postmenopausal women and patients who underwent vaginal surgery before. After the accurate diagnosis, patients should be operated as soon as possible, and necessary surgery should be done.

Association between genetic polymorphism and levothyroxine bioavailability in hypothyroid patients.

Thyroid hormones play a vital role in the human body for growth and differentiation, regulation of energy metabolism, and physiological function. Hypothyroidism is a common endocrine disorder, which generally results from diminished normal circulating concentrations of serum thyroxine (fT4) and triiodothyronine (fT3). The primary choice in hypothyroidism treatment is oral administration of levothyroxine (L-T4), a synthetic T4 hormone, as approximately 100-125 µg/day. Generally, dose adjustment is made by trial and error approach. However, there are several factors which might influence bioavailability of L-T4 treatment. Genetic background could be an important factor in hypothyroid patients as well as age, gender, concurrent medications and patient compliance. The concentration of thyroid hormones in tissue is regulated by both deiodinases enzyme and thyroid hormone transporters. In the present study, it was aimed to evaluate the effects of genetic differences in the proteins and enzymes (DIO1, DIO2, TSHR, THR and UGT) which are efficient in thyroid hormone metabolism and bioavailability of L-T4 in Turkish population. According to our findings, rs225014 and rs225015 variants in DIO2, which catalyses the conversion of thyroxine (pro-hormone) to the active thyroid hormone, were associated with TSH levels. It should be given lower dose to the patients with rs225014 TT and rs225015 GG genotypes in order to provide proper treatment with higher effectivity and lower toxicity.

A rare cause of hemoperitoneum: A case report of ruptured ileocolic artery aneurysm.

Visceral artery aneurysm (VAA) is very rare among vascular pathologies. Incidence reported in autopsy series and angiographic studies varies between 0.1% and 0.2%. Most cases are asymptomatic and are diagnosed as result of complications, or incidentally, when imaging is performed for another reason. Three percent of VAAs are superior mesenteric artery (SMA) terminal branch aneurysms. Intra- and/or extraperitoneal bleeding due to ruptured aneurysm is life-threatening condition and requires emergent intervention. Therefore, surgical or endovascular interventional treatment must be performed rapidly after diagnosis. Presently described is case of ileocolic artery aneurysm in a patient admitted with abdominal pain, nausea, and vomiting. Endovascular intervention had been planned; however, during hospitalization, aneurysm ruptured and emergent surgery was performed. Review of the literature is also presented.

Damage-control laparoscopic partial cholecystectomy with an endoscopic linear stapler.

OBJECTIVE: Several damage-control procedures have been described in the literature in case of severe Calot's triangle inflammation and fibrosis. In this report, we describe patients who underwent laparoscopic partial cholecystectomy using an endoscopic linear stapler. MATERIALS AND METHODS: Five patients with acute cholecystitis underwent laparoscopic partial cholecystectomy in our clinic between January - December 2011. All patients had severe fibrosis and inflammation of Calot's triangle. The anterior and posterior walls of the gallbladder were totally resected if possible. The gallbladder was transected at its neck or Hartmann's pouch, leaving a remnant gallbladder pouch behind. RESULTS: Five patients had laparoscopic partial cholecystectomy with an endoscopic linear stapler. The main symptom of all patients on admission to the emergency room was abdominal pain. The mean time for the surgical procedure was 140 minutes (range, 120-180 minutes). Inflammation and fibrosis of Calot's triangle was detected in all patients during surgery and a phlegmonous gallbladder was detected in one patient. Surgical drains were used in all patients and no biliary leakage was detected. Remnant common bile duct calculi were detected in one patient and this patient underwent endoscopic retrograde cholangiopancreatography one month after surgery. CONCLUSIONS: When a reliable view of Calot's triangle cannot be obtained due to severe inflammation and fibrosis during laparoscopy, laparoscopic partial cholecystectomy seems to be a safe and feasible alternative to open surgery with an acceptable morbidity rate.

Thyroid cancer incidence in simultaneous thyroidectomy with parathyroid surgery.

OBJECTIVE: Primary hyperparathyroidism (PHPT) is often seen in conjunction with an underlying thyroid disorder. Imaging methods that are used to localize the parathyroid adenoma also detect associated thyroid nodules and thyroid cancer. The aim of this study was to detect the rate of thyroid cancer identified while performing parathyroidectomy and thyroidectomy in patients with PHPT. MATERIAL AND METHODS: Files of all patients who were operated for PHPT and who underwent simultaneous thyroidectomy were analyzed. Data regarding parathyroid pathology, surgical procedures, indications of thyroid surgery, and pathology results were retrospectively recorded. The indications for thyroid surgery included presence of suspicious thyroid nodules in ultrasonography, increase in size of thyroid nodules in follow-up ultrasound, or presence of suspicious thyroid fine needle aspiration biopsy (FNAB) findings. Rates of thyroid cancer detection were investigated according to definite pathology reports. RESULTS: Eighty-three patients who underwent parathyroidectomy with a diagnosis of PHPT with concurrent thyroidectomy in Department of General Surgery, Istanbul University Istanbul Faculty of Medicine were included in the study. Eighteen patients were male (22%) and 65 were female (78%). The median age was 53 (18-70) years. The primary indication for parathyroidectomy was primary hyperparathyroidism in all patients. The thyroid procedures applied in addition to parathyroidectomy were lobectomy + isthmusectomy in 29 patients (35%), bilateral subtotal thyroidectomy in 20 patients (24%), bilateral total thyroidectomy in 23 patients (28%), and total thyroidectomy on one side and near total thyroidectomy to the other side in 11 patients (13%). The only indication for thyroidectomy was the presence of thyroid nodules until 2000 (20 patients, 24%). Indications in the remaining 63 patients included the presence of multiple nodules that cannot be followed up by ultrasonography in 25 patients (30%), presence of a suspicious nodule on ultrasonography in 33 patients (40%), growth in nodule size in 2 patients (2%), and detection of suspicious findings on FNAB in 3 patients (4%). Five patients (6%) were diagnosed with papillary thyroid cancer, four of whom were micropapillary cancer. CONCLUSION: Imaging methods performed to localize the pathological parathyroid gland for a diagnosis of PHPT are useful in estimating other accompanying pathologies. Presence of thyroid nodules should be evaluated before all parathyroid procedures, and if the nodule has an indication for surgery, thyroid surgery should be considered at the same operation with parathyroid surgery.

Effects of tissue plasminogen activator in experimentally induced peritonitis.

BACKGROUND: We aimed to evaluate the microbiological and immunological effects of tissue plasminogen activator (tPA) in a rat model of peritonitis. METHODS: Twenty-four male Wistar albino rats were divided equally into three groups. Peritonitis and thereafter laparotomy and partial omentectomy were performed in all rats. The control group (C) had no further treatment. The antibiotics group (A) received metronidazole and ceftriaxone. The antibiotic and tPA group (A+T) received the same antibiotics as well as tPA. For microbiological and immunological analysis, blood samples were obtained at the 24th hour, and peritoneal fluid samples were obtained at the 24th and 72nd hours. On the fifth day after surgery, all rats were sacrificed, and the macroscopic findings of the peritoneal cavity were recorded. RESULTS: The mean number of intraperitoneal abscesses was significantly higher in the control group and the lowest in the two treatment group (A+T). The levels of cytokines were not significantly different between groups. Giving tPA reduced the number and sizes of the abscesses with no significant difference in inflammatory response. CONCLUSION: In this experimental peritonitis model, it can be postulated that tPA decreased abscess formation without exaggerating the inflammatory response.

The role of colorectal stent placement in the management of acute malignant obstruction.

BACKGROUND: In recent decades, the use of colorectal stents for palliation or as a bridge to surgery in acute malignant colorectal obstruction has increased. We aimed to evaluate the technical and clinical efficacy, safety and clinical outcomes of endoscopic stenting for the relief of acute colorectal obstruction secondary to cancer. METHODS: From March 2006 to December 2012, among 100 patients with acute malignant colorectal obstruction, stenting procedures were performed on 42 patients for relief of obstruction. Uncovered self-expanding metal stents (SEMS) were placed endoscopically under fluoroscopic guidance in all patients. Using the patient database, a review was conducted to determine the effectiveness of the procedure and the short- and long-term complications. RESULTS: Stent placement was technically successful in 39/42 (92.8%) and clinically successful in 38/42 (90.4%) patients. Sixteen patients later underwent an elective surgical resection, and in 26 patients with metastatic disease or comorbidity, stent placement was palliative. Complications occurred in 10 (23.8%) patients, and the most common was tenesmus (n=3). Migration, bleeding, and recto-sigmoid perforation occurred in two patients each. Stent obstruction due to fecal impaction was seen in one case. CONCLUSION: Stent placement for colorectal obstruction is an effective and relatively safe procedure, with minor complications. It not only allows subsequent elective resection, but is also definitive for palliative treatment in patients with obstructive colorectal cancer.

Role of dissemination of microorganisms during laparoscopic appendectomy in abscess formation.

BACKGROUND: The aim of this study was to investigate the potential contributory role of laparoscopic appendectomy in the occurrence of postoperative intra-abdominal infections. METHODS: A prospective single-center study including 48 patients who underwent laparoscopic appendectomy was conducted between August 2010 and September 2011. Two peritoneal samples were obtained from each patient in the pre- and post-appendectomy period. Aerobic and anaerobic microbiological cultures were obtained from the samples. The data were analyzed with statistical methods. RESULTS: The mean age of the 48 patients (29 male, 19 female) was 10.9 years. Among the pre-appendectomy aerobic cultures, microorganisms were isolated in 18 of the patients (38%), with Escherichia coli being the most common. In post-appendectomy aerobic cultures, various bacteria were isolated in 7 patients (14.6%), with the numbers of bacteria statistically significantly reduced (p<0.05). Anaerobic microorganisms were isolated in 12 patients (25%) and 4 patients (8.3%) in pre- and post-appendectomy cultures, respectively, with Bacteroides fragilis the most common organism; there was a significant reduction in the bacterial count (p<0.05). Each patient was regarded as their own control. CONCLUSION: Our results suggest that laparoscopic appendectomy does not cause an increase in intra-abdominal infections, and particularly not infections associated with anaerobic bacteria.

Increased interleukin 1 and tumor necrosis factor alpha levels after thyroid surgery.

OBJECTIVE: The aim of this study was to consider levels of the proinflammatory cytokines IL-1 and TNFα after thyroid surgery. MATERIAL AND METHODS: A total of 200 patients who underwent total thyroidectomy enrolled in this study. Drain fluid samples were taken. IL-1 and TNFα results and their relationship with other factors were analyzed. RESULTS: There was a positive correlation between IL-1 and hyperthyroidism (rs=0.614, p<0.001), operative time (rs=0.770, p<0.001), and excised thyroid volume (rs=0.829, p<0.001). Moreover, there was a positive correlation between TNFα and hyperthyroidism (rs=0.430, p<0.001), operative time (rs=0.392, p<0.001), and excised thyroid volume (rs=0.398, p<0.001). CONCLUSION: The results of this study showed us that the parameters related to increased proinflammatory cytokine levels after thyroid surgery were hyperthyroidism, operative time, and excised thyroid volume, but this increase did not show us any clinical outcomes related to these parameters.

Factors that affect the false-negative outcomes of fine-needle aspiration biopsy in thyroid nodules.

Background. The purpose of this study was to assess the factors that affect the false-negative outcomes of fine-needle aspiration biopsies (FNABs) in thyroid nodules. Methods. Thyroid nodules that underwent FNAB and surgery between August 2005 and January 2012 were analyzed. FNABs were taken from the suspicious nodules regardless of nodule size. Results. Nodules were analyzed in 2 different groups: Group 1 was the false-negatives (n = 81) and Group 2 was the remaining true-positives, true-negatives, and false-positives (n = 649). A cytopathologist attended in 559 (77%) of FNAB procedures. There was a positive correlation between the nodule size and false-negative rates, and the absence of an interpreting cytopathologist for the examination of the FNAB procedure was the most significant parameter with a 76-fold increased risk of false-negative results. Conclusion. The contribution of cytopathologists extends the time of the procedure, and this could be a difficult practice in centres with high patient turnovers. We currently request the contribution of a cytopathologist for selected patients whom should be followed up without surgery.

Clinical challenges in drug induced pancreatitis: Presentation of two cases and review of the literature.

INTRODUCTION: A wide variety of drugs have been reported to cause pancreatitis. Although the incidence of drug induced acute pancreatitis is low, the disease is associated with substantial morbidity and mortality, which makes timely identification of the causative agent important. PRESENTATION OF CASE: Herein, we report two patients with clinical, biochemical, and radiological evidence of acute pancreatitis. There were no etiologic factors except their prescribed drugs. DISCUSSION: The majority of patients with acute pancreatitis recover uneventfully, but there remains an uncontrollable risk of mortality. It is prudent to withdraw a medication with a known association with acute pancreatitis. Necessity of multi-drug regimens especially in oncological patients however, presents a challenge. CONCLUSION: Corticosteroid pulse therapy was easily detectable as the causative agent in our first case, but combined anti-neoplastic drug therapy and additional multi-drug regimen presented great difficulties in identifying single causative agent in our second patient.

Iatrogenic major vascular injury during lumbar discectomy: report of three cases.

Iatrogenic vascular injury rarely occurs during lumbar disc surgery and can be fatal if it is not recognized instantly. In this paper we aim to introduce three iatrogenic vascular injuries that occurred during the lumbar disc surgery. The first case was consulted because of the sudden hypotension attack during lumbar disc surgery. The left common iliac artery and bilateral common iliac vein injuries were detected in emergency laparotomy, and repaired primarily. The second case was consulted to our clinic because of the hypotension attack at the first postoperative day. Left common iliac artery and vein injuries were diagnosed by CT angiography. Left common iliac vein was ligated and left common iliac arterial injury was repaired primarily by laparotomy. The third case was referred to our clinic for left lower extremity ischemia. Left common iliac artery injury was diagnosed by simple physical examination. Reconstruction by PTFE graft interposition was performed. The first patient died due to disseminated intravascular coagulation at the early postoperative period. Pulmonary embolus developed in the iliac vein ligated patient but was well treated by anticoagulant therapy. The last patient was discharged without any problem. Two of the patients are well on long-term follow-up.

ERCP without radiation during pregnancy in the minimal invasive world.

BACKGROUND: The current guidelines recommend endoscopic retrograde cholangiopancreatography (ERCP) procedures in pregnant women with minimal radiation exposure. Regarding the safety of ERCP during pregnancy, data are limited in the literature. In this study, we report our experience with five ERCP procedures performed in five pregnant women without radiation at a single tertiary health center. METHODS: Between May 2007 and February 2012, five pregnant patients underwent ERCP without radiation, analyzed retrospectively. Clinical disease was confirmed with either pre-procedure ultrasonography and magnetic resonance cholangiopancreatography in all patients. In all cases, selective deep cannulation was performed and confirmed by the aspiration and/or direct visualization of the bile. The data regarding laboratory, ultrasonography, magnetic resonance imaging, endoscopic findings, and clinical course of the patients were analyzed. Fetal complications were noted at delivery and 30 days postdelivery follow-up. RESULTS: The mean patient age was 26 years (22-33) and the mean duration of pregnancy was 20 weeks (12-32). In all cases, no secondary ERCP procedures were needed. Also, no maternal and fetal adverse events and complications were determined after the procedures or on follow-up. All stages of the procedure including cannulation, sphincterotomy, and stone extraction were performed without the use of fluoroscopy. CONCLUSION: As far we know, there is no report in the literature regarding the failure of endoscopic retraction of stones without fluoroscopy during pregnancy. Our series notes that ERCP is safe and prevents recurrent biliary pancreatitis during pregnancy. Unfortunately, due to the small limited number of patient data, our study notes the requirement of further large randomized and controlled series.
