Evaluation of three instruments for laparoscopic cholecystectomy: harmonic scalpel, bipolar vessel sealer, and conventional technique

AIM

Laparoscopy is the gold standard procedure in the surgery of gall bladder. Harmonic scalpel and bipolar vessel sealer are the other instruments for laparoscopic cholecystectomy. The aim of this study is to compare the effectiveness and safety of the three instruments for laparoscopic cholecystectomy.

METHODS

A total of 60 patients were included into the study. Patients were divided into three groups. In Group A, cystic duct and artery were sealed using laparoscopic clips and gall bladder was dissected from the hepatic bed using electrocautery. In Group B, cystic duct and artery were sealed using Harmonic scalpel and gall bladder was dissected from the hepatic bed using Harmonic scalpel. In Group C, cystic duct and artery were sealed using Bipolar vessel sealer and gall bladder was dissected from the hepatic bed using Bipolar vessel sealer. Groups were compared for the following parameters: duration of surgery, amount of drainage, cystic duct opening pressure and cost.

RESULTS

The duration of surgery was 31.5 ± 11.1 minutes in Group B, 33.1 ± 10 minutes in Group A, and 36.5 ± 9.9 in Group C; and the difference between Group B and Group C was statistically significant (P<0.04). Cystic duct opening pressure was highest in Group A which was 324.0 ± 23.4 mmHg. For all of these 3 groups total cost was found to be 900$, 2900$, 1800$ for groups A, B, and C; respectively.

CONCLUSION

In laparoscopic cholecystectomy different energy source instruments may be safe to use with a cautious dissection and sealing of the cystic duct.

Lacrimal gland marginal zone lymphoma: regression after treatment of chronic hepatitis C virus infection: case report and review of the literature

A 43-year-old woman was first admitted to the ophthalmology clinic with the complaint of a mass compressing the right eye. Based on clinical and laboratory examinations she was diagnosed as having marginal zone lymphoma (MZL) of the right lacrimal gland in addition to hepatitis C virus (HCV) infection. After the treatment for HCV infection with pegylated interferon plus ribavirin, a radiographic response of the MZL was obtained; she remains in remission through thirty months of clinical follow-up. In this case, the treatment of HCV infection led to regression of MZL suggesting the necessity of testing for HCV infection and treatment of the HCV infection should be highly considered in all HCV-positive patients with MZL's.

Serum amyloid A and haptoglobin concentrations and liver fat percentage in lactating dairy cows with abomasal displacement

BACKGROUND

There has been increased interest in measuring the serum concentration of acute phase reactants such as serum amyloid A [SAA] and haptoglobin [haptoglobin] in periparturient cattle in order to provide a method for detecting the presence of inflammation or bacterial infection.

OBJECTIVES

To determine whether [SAA] and [haptoglobin] are increased in cows with displaced abomasum as compared with healthy dairy cows.

ANIMALS

Fifty-four adult dairy cows in early lactation that had left displaced abomasum (LDA, n = 34), right displaced abomasum or abomasal volvulus (RDA/AV, n = 11), or were healthy on physical examination (control, n = 9).

MATERIALS AND METHODS

Inflammatory diseases or bacterial infections such as mastitis, metritis, or pneumonia were not clinically apparent in any animal. Jugular venous blood was obtained from all cows and analyzed. Liver samples were obtained by biopsy in cattle with abomasal displacement.

RESULTS

[SAA] and [haptoglobin] concentrations were increased in cows with LDA or RDA/AV as compared with healthy controls. Cows with displaced abomasum had mild to moderate hepatic lipidosis, based on liver fat percentages of 9.3 +/- 5.3% (mean +/- SD, LDA) and 10.8 +/- 7.7% (RDA/AV). [SAA] and [haptoglobin] were most strongly associated with liver fat percentage, r(s) = +0.55 (P < .0001) and r(s) = +0.42 (P = .0041), respectively.

CONCLUSIONS AND CLINICAL IMPORTANCE

An increase in [SAA] or [haptoglobin] in postparturient dairy cows with LDA or RDA/AV is not specific for inflammation or bacterial infection. An increase in [SAA] or [haptoglobin] may indicate the presence of hepatic lipidosis in cattle with abomasal displacement.

Craniorachischisis totalis: a case report and review of the literature

OBJECTIVE

To discuss a fetus with craniorachischisis diagnosed antenatally and to review the literature.

METHOD

Case report.

RESULTS

Craniorachischisis was detected on ultrasound scan in a fetus at gestational week 13. Pregnancy was terminated and diagnosis was verified postnatally.

CONCLUSION

Craniorachischisis is a rare and severe form of neural tube defects (NTDs). The majority of currently known cases of mouse craniorachischisis have been found to result from disturbance of a single molecular signaling cascade, called planar cell polarity pathway (PCP). The mutant genes that have been causative in disturbance of PCP in mouse models have been examined in human malformations but none of them have so far been implicated in human craniorachischisis. To date, no other genes except the gene encoding 5,10-methylenetetrahydrofolate reductase have been specifically implicated in predisposition to NTDs. We suggest that other PCP genes should be considered as candidates for a role in the etiology of human NTDs. Further investigations are therefore necessary.

Comparison of serum CA 19.9, CA 125 and CEA levels with severity of chronic obstructive pulmonary disease

OBJECTIVE

To investigate serum levels of CA 19.9, CA 125 and carcinoembryonic antigen (CEA) in patients with different stages of chronic obstructive pulmonary disease (COPD).

PATIENTS AND METHODS

Fifty-three consecutive patients (50 males, 3 females, mean age 67.6 +/- 10.1 years) with COPD were included in this study. Serum levels of CA 19.9, CA 25 and CEA were determined by the chemiluminescent immunometric method. Based on values obtained from pulmonary function tests, the patients were divided into 3 groups: moderate (21), severe (18) and very severe (14). Data were analyzed with a Kruskal-Wallis one-way analysis of variance test and Mann-Whitney U test.

RESULTS

The mean serum levels of CA 125 and CA 19.9 were significantly higher in patients with very severe COPD (p = 0.013 and p = 0.017, respectively) than in patients with severe and moderate COPD (p < 0.05). Patients with cor pulmonale had significantly high mean serum levels of CEA, CA 19.9 and CA 125 (p < 0.05). Patients using a long-acting beta-agonist and theophylline showed significantly higher mean serum levels of CA 125 than patients who were not (p < 0.05).

CONCLUSION

Data showed that the increased serum tumor markers in patients with COPD might be due to the severity of COPD, medication and cor pulmonale.

Prenatal diagnosis of a case probably with Oral-Facial-Digital Syndrome--Gabrielli type

We report here a case with microcephaly, preauricular pits, cleft lip-palate, hypertelorism, multiple frenula and preaxial polydactyly. The clinical picture overlaps with many syndromes, but it is mostly consistent with oral-facial-digital syndrome, Gabrielli type. There are no previously reported cases of this syndrome presenting also with microcephaly. On the other hand, it is hard to differentiate this clinical picture from Goldenhar syndrome (Oculo-auriculo-vertebral spectrum), and oculo-auriculo-fronto-nasal syndrome because of many overlapping features.

Polycystic ovary syndrome and prolactinoma association

Hyperprolactinemia is the most common pituitary hormone hypersecretion syndrome in both men and women. Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies affecting 5%-10% of reproductive age women. Here, we present a patient with irregular menses, obesity, hirsutism and infertility, and hyperprolactinemia who was diagnosed as PCOS and prolactinoma and admitted to our clinic. Prolactinoma and PCOS association is a rare condition. This 33-year-old woman was admitted to the internal medicine outpatient clinic for irregular menses, obesity, hirsutism and infertility, and hyperprolactinemia. Her laboratory results were as follows: prolactin was 74 ng/mL (normal range:1.8-20.3 ng/mL). Pelvic ultrasonography was correlated with polycystic ovary syndrome. Pituitary MRI showed 6x8 mm microadenoma at left half. Bromocriptine was started with 1.25 mg/day and increased to 5 mg/day. After six months of bromocriptine treatment her prolactin level was normal and no adenoma was detected in pituitary MRI. PCOS and prolactinoma association should be taken into account in PCOS cases with mild hyperprolactinoma.

Guillain-Barré syndrome associated with Legionnella infection

This is the first report of Guillain-Barré syndrome (GBS) related to Legionnella pneumophilia infection. A 13-year-old boy presented with acute dysphagia and dyspnea. He lived in a rural area and had a history of drinking potable deep-hole water. The patient was intubated because of increased respiratory distress. A positive direct fluoresein antigen test confirmed L. pneumophilia infection in BAL. One week after the first admission, acute weakness was noticed including the lower extremities and was more prominent in the distal than the proximal portions. GBS was considered as the initial diagnosis. Tests for all causes known to trigger GBS were negative. Specific serology for L. pneumophilia IgG was positive. He was treated with intravenous immunoglobulins and discharged with minor weakness and difficulty in walking in the second month. On the basis of this case, L. pneumophilia should be included in the etiologic spectrum of GBS.

A case with diffuse uterine leiomyomatosis and review of the literature

Leiomyomas and diffuse uterine leiomyomatosis are smooth muscle tumors of the uterus. Diffuse uterine leiomyomatosis is a benign and extremely rare condition in which the uterus is symmetrically enlarged as a result of the almost complete replacement of the myometrium by innumerable poorly defined, confluent nodules. The etiology of these neoplasms is not completely understood. Initial symptoms of the diffuse uterine leiomyomatosis usually are abdominal pain and abnormal uterine bleeding. Similar to uterine leiomyomas, patients with leiomyomatosis present with menorrhagia, dysmenorrhea, abdominal pain, infertility, and pelvic pressure. Hormonal treatment usually fails to control the symptoms, anemia, or tumor growth after treatment is stopped. As a result, despite patients being in the third or fourth decades of life, hysterectomy has been the only permanent treatment option offered to patients for treatment of the symptoms related to uterine fibroids in diffuse leiomyomatosis. A case of a patient with a huge uterine mass (2,650 g in weight) who underwent hysterectomy due to diffuse uterine leiomyomatosis is presented together with a review of the literature.

A prenatally diagnosed case of sirenomelia with polydactyly and vestigial tail

We are presenting a prenatally diagnosed case with sirenomelia, vestigial tail and polydactyly. A 30-year-old woman at 16 weeks of gestation with dichorionic twins was admitted to the hospital. Prenatal ultrasound demonstrated fusion of the lower limbs in one member and normal femurs, tibias and fibulas, and normal vertebras in the second twin, suggesting the diagnosis of sirenomelia. The twins were delivered vaginally at 35 weeks after spontaneous onset of labor. The affected newborn died after 24 hours and postnatal examination revealed unseparated lower limbs with extreme retroversion, bilateral pes equinus, unilateral postaxial polydactyly, a vestigial tail on the sacral region, a large and wide penis and anal atresia. There is only one previous report of sirenomelia with vestigial tail in the literature. However, a large, wide penis and polydactyly have not been reported before in association with this anomaly.

CA 19-9 can be a useful tumor marker in ovarian dermoid cysts

PURPOSE

To evaluate the importance of CA-19-9 as an aiding tool in the diagnosis of mature cystic teratomas.

METHODS

We found 43 cases of dermoid cysts that were operated on at our clinic, and whose tumor marker CA 19-9 was studied before the operation.

RESULTS

Thirty-seven of 43 patients (86%) had elevated CA 19-9 levels. Using Pearson's correlation, the average diameter and weight of the tumor had a strong possitive correlation with the level of CA 19-9 (p < 0.01). Thirty-one out of the 43 (72%) cases had a dermoid cyst in the right ovary, nine (20.9%) in the left ovary, and three (7%) had bilateral dermoid cysts. Right predominancy was very high among the patients (p < 0.05).

CONCLUSION

We suggest that besides ultrasonography and computed tomography, serum CA 19-9 level could be a useful tumor marker in the diagnosis of dermoid cysts.

Atypical imaging findings of infantile hemangioendothelioma: a case report

Infantile hemangioendothelioma is the third most common hepatic tumor in children, and the most common benign vascular tumor of the liver in infancy. On computed tomography (CT) and magnetic resonance imaging (MRI), typical enhancement patterns similar to those seen in adult hemangiomas may help establish the diagnosis. However, atypical enhancement patterns may also occur. In this paper, we report a rare form of solitary infantile hemangioendothelioma that showed a rim-like calcification and rim-like enhancement on CT and MRI.

Interaction between Chlamydia pneumoniae seropositivity, inflammation and risk factors for atherosclerosis in patients with severe coronary stenosis

OBJECTIVE

To investigate whether Chlamydia pneumoniae (Cpn) seropositivity in patients with suspected coronary artery disease (CAD) (n = 81) is associated with increases in markers of inflammation, the severity of coronary atherosclerosis, and traditional risk factors for cardiovascular events.

MATERIAL AND METHODS

The severity of coronary atherosclerosis was ranked by Gensini score. Inflammation and endothelial dysfunction were evaluated using white blood cell counts and levels of high-sensitivity C-reactive protein (hs-CRP), ferritin, tumour necrosis factor-alpha (TNF-alpha), interleukins 1beta and 6 (IL-1beta, IL-6), soluble intercellular adhesion molecule-1 (sICAM-1), E-selectin and oxidized LDL (oxLDL), and these were compared between Cpn-seropositive and seronegative individuals.

RESULTS

IgA and IgG Cpn seropositivity were significantly associated with the presence of CAD (p = 0.005) and were independent predictive factors for the severity of coronary atherosclerosis (p = 0.005). Elevated levels of IL-6 (p = 0.027) and triglyceride (p = 0.038) and low levels of high-density lipoprotein cholesterol (HDL-C) (p = 0.038) were significantly predicted by Cpn IgA and IgG seropositivity.

CONCLUSIONS

Seropositivity for Cpn is a risk factor for patients with significant angiographically documented coronary stenosis. Additionally, Cpn seropositivity was significantly associated with dyslipidemia and elevated IL-6, known risk factors for CAD. These observations indicate that Cpn infection may be one entry point to the causal or contributory pathways that lead to atherosclerosis and its clinical manifestations.

Surgical treatment of complicated pilonidal disease: limited separate elliptical excision with primary closure

OBJECTIVE

We aimed at treating complicated pilonidal sinus (PS) patients by a simple and effective surgical procedure.

METHOD

Between 2000 and 2004, 24 selected complicated PS patients were treated with 'limited separate elliptical excision and primary closure'. Patients with extensive or bilateral gluteal involvement, having more lateral, caudal or cephalic sinuses, multiple recurrences and unhealed chronic wounds after pilonidal surgery were included. Asymmetric excision and primary closure was performed to main diseased tissue in the midline. Additionally, small separate elliptical excisions with primary closure were performed in other involved tissues. The fistula tract or granulation tissue were excised subcutaneously if present. All patients were operated under local anaesthesia. The fascial attachments between the skin and coccyx were released at the deep point in the midline and at one side of wound. Suction drains and prophylactic antibiotics were used; subcutaneous tissues were closed with running polyglactin sutures and skin with polypropylene subcutaneously.

RESULTS

The mean age of patients was 28.4 years (range 18-38). The mean follow-up time was 2.8 years. One recurrence, one seroma, one wound infection and one wound breakdown were recorded. Healing was always by first intention except in patients with wound infection and breakdown.

CONCLUSION

Most of the complicated PS patients can be operated with acceptable rates of recurrences and complications by using 'limited separate elliptical excisions with primary closure'.

The level of serum ionised calcium, aspartate aminotransferase, insulin, glucose, betahydroxybutyrate concentrations and blood gas parameters in cows with left displacement of abomasum

The purpose of this study was to determine concentrations of serum glucose, aspartate aminotransferase (AST), insulin, beta-hydroxybutyrate (BOH) and ionised calcium (Ica) in dairy cows with left displaced abomasum (LDA) and to compare these parameters before and after surgical correction of LDA. Eighteen Swiss-Holstein dairy cows with LDA were used in this study. Clinically healthy post parturient cows (n: 10) from a local dairy farm were used as control group. Blood samples were collected from the jugular vein from all the cows. Surgery was performed in cows with LDA. Blood samples from cows with LDA were collected 24 hours after surgery. The abomasum was repositioned followed by an omentopexy. Six of the 18 cows with LDA had clinical ketosis as detected with urine dipstick. The mean concentrations of insulin, BOH, glucose and AST in cows with LDA at admission time were increased compared with the healthy cows. But the mean concentration of ICa at admission time was slightly decreased compared with healthy cows. The mean BOH concentration was decreased 24 hours following surgery compared with values on admission time. However, the mean serum AST levels were increased both at admission time and 24 hours after surgery compared with healthy cows. The levels of blood gas parameters in cows with LDA were not significantly different in comparison with healthy cows, although hyperbasemia in six of 18 cows with LDA was determined. In conclusion, the results of this study indicated that serum insulin, glucose, AST and BOH levels were increased in dairy cows with LDA. Serum BOH and ICa levels were decreased 24 hours after surgery compared with values on admission time. All cows with LDA used in this study had subclinical/clinical ketosis. We could say that ketosis might be a risk factor for the displacement of the abomasum.

Benign cystic mesothelioma presenting as a huge pelvic mass--a case report

Benign cystic mesothelioma is an extremely rare peritoneal tumor. It is reported in women of childbearing [corrected] age but also in males and needs a careful [corrected] differential diagnosis between benign and malign neoplasia to choose the most [corrected] adeguate therapy. A 25-year-old female [corrected] was treated in our clinic for a gigantic cystic mass (25 x 22 x 3 cm in diameter) containing [corrected] many to [corrected] cysts of different sizes. All tumoral markers were within normal range. Surgical [corrected] treatment consisted of radical excision of the mass and the prognosis was good [corrected].
