The impact of a percutaneous cholecystostomy catheter in situ until the time of cholecystectomy on the development of recurrent acute cholecystitis: a historical cohort study

Background: the optimal duration of percutaneous cholecystostomy in patients with acute cholecystitis is unknown. Methods: this study was a retrospective analysis of patients (age ≥ 18 years) who underwent percutaneous cholecystostomy due to acute calculous cholecystitis. Patients were grouped according to treatment modality: percutaneous cholecystostomy as a definitive treatment (group 1), subsequent surgical treatment after the removal of the catheter (group 2) and those remaining in situ (group 3). The development of gallstone-related complications was the main outcome. Results: there were 24 females (43.6%) and 31 males (56.4%) included in the study with a mean age of 64.8 ± 15.9 years. There were 16 (29.1%), 19 (34.5%) and 20 (36.4%) patients in groups 1, 2, and 3, respectively. The catheter withdrawal time for group 1 and group 2 was 18.2 ± 6.9 and 20.7 ± 13.4 days, respectively. Surgical treatment was performed after a mean of 85.4 ± 93.5 days following catheter removal in group 2 and a mean of 64 ± 32.5 days while the PC tube was in place in group 3. There were one (6.3%) and two cases of a recurrence (10.5%) in groups 1 and 2, respectively. Two patients developed choledocholithiasis (10%) in group 3. Conclusion: maintaining percutaneous cholecystostomy tubes in place until the time of surgery in surgically fit patients may help to prevent a recurrence after acute calculous cholecystitis

Diffusion MRI on lymph node staging of gastric adenocarcinoma.

OBJECTIVE: The purpose of this study was to evaluate the accuracy of diffusion weighted magnetic resonance imaging (MRI) in preoperative assessment of metastatic lymph nodes of gastric cancer. METHODS: A total of 23 gastric cancer patients with a mean age of 59.4±10.9 years were analyzed. Lymph nodes were grouped as perigastric lesser curvature (Group Ia), perigastric greater curvature (Group Ib), D1+/D2 lymph nodes (Group II). Identification of histologically metastatic lymph nodes by diffusion weighted MRI was regarded as the main outcome. RESULTS: A total of 1,056 lymph nodes including 180 histologically proven metastatic lymph nodes were dissected. Although diffusion weighted MRI could identify the metastatic lymph nodes in 18 out of 23 patients (77.8%), only 69 of total 1,056 nodes (6.53%), either metastatic or non-metastatic, could be detected. There was no correlation between histopathology and diffusion weighted MRI with regard to lymph node groups (P>0.05 for all). Overall accuracy was calculated as 69.56, 65.21 and 52.17 for Groups II, Ib and Ia lymph nodes, respectively. Apparent diffusion coefficient (ADC) values could not be helpful to differentiate metastatic lymph nodes (P=0.673). CONCLUSIONS: Diffusion weighted MRI has low accuracy to detect or to differentiate metastatic and non-metastatic lymph nodes based on their ADC values in gastric cancer.

Does adrenaline spraying over thyroidectomy area reduce bleeding?

BACKGROUND: Means to prevent and control intra- or postoperative bleeding remain a topic of utmost importance in thyroidectomy. In this randomised clinical trial, we used adrenaline spraying to see if it helps bleeding control and reduces drainage and hematoma formation after thyroidectomy. METHODS: After total thyroidectomy, 1 mg/ml adrenaline solution in 10 ml saline was sprayed all over the operation area by a syringe in 40 patients of "Adrenaline (+) Group". In the other 40 patients in "Adrenaline (-) Group", only standart total thyroidectomy was performed. Drainage amounts of 24 hours were recorded. RESULTS: Among 80 patients, 66 (82.5%) were female and 14 (17.5%) were male. The daily drainage amounts of the Adrenaline (+) Group were found statistically significantly lower than the Adrenaline (-) Group (p<0.05). In both of the groups, thyroid volumes were significantly correlated with the drainage amounts. "p" values were 0.008 and <0.001 in Adrenaline (+) and Adrenaline (-) Groups, respectively. CONCLUSIONS: Preliminary experience using adrenaline has been encouraging and it is useful as an adjunct to thyroid surgery in order to prevent hemorrhagia and give up drain placement. But prospective randomized trials using adequate patient numbers are still needed to validate efficacy and safety.

Is concomitant cholecystectomy with laparoscopic sleeve gastrectomy safe?

BACKGROUND/AIMS: To study the effect of selective concomitant cholecystectomy (SCC) on laparoscopic sleeve gastrectomy (LSG). MATERIALS AND METHODS: A retrospective case-control study of 16 morbidly obese patients treated with concomitant LSG as the primary bariatric surgery and SCC for proven gallbladder (GB) pathology (Group A) between November 2010 and February 2013 was performed. Randomly selected 32 patients who underwent laparoscopic sleeve gastrectomy was the control group (Group B). RESULTS: A total of 48 patients with a mean age of 35.5±10.7 years were included. Demographic data of groups were similar except that there were more female patients in the Group A (p=0.036). Mean body mass index (kg/m2) was 51.1±5.6 and 50.9±5.4 in Groups A and B, respectively (p=0.894). The mean operative time for patients with and without cholecystectomy was 157.2±40 and 95.72±6.2 min, respectively (p=0.001). Cholecystectomy resulted in an additional mean operative time of 49.1±27.9 min without any specific complication. There was no statistical difference with regard to overall morbidity (p=0.316) and the length of hospital stay (p=0.528) between groups. CONCLUSION: Although an increase in operative time may be an important issue, SCC can be performed on all patients with proven GB pathology during LSG without an increase in morbidity or length of hospital stay.

Cinical Significance of Androgen Receptor, CK-5/6, KI-67 and Molecular Subtypes in Breast Cancer.

OBJECTIVE: To detect the relationship between molecular subtypes of breast cancer with expressions of androgen receptor, cytokeratin 5/6 (CK5/6)and Ki-67. MATERIALS AND METHODS: Expressions of androgen receptor, CK-5/6 and Ki-67 were determined by immunohistochemistry in paraffin-embedded sections obtained from 86 invasive breast cancer cases of stages I/IIa/IIb in 4 molecular subtypes. Patients treated for recurrent disease and locally advanced disease were excluded. RESULTS: Forty one luminal A cases, ie. positive estrogen receptor(ER) and/or progesteron receptor (PR) with negative epidermal growth factor receptor (HER2), 14 luminal B, ie. positive ER and/or PR and positive HER2, 14 HER2-enriched (HER2+), ie. negative ER and PR with positive HER2, and 17 triple negative (negative ER and PR and HER2) invasive breast cancers were included. Mean follow-up was 17.46±11.70 mo. Androgen receptor-negativity and CK5/6-positivity were significantly more common in HER2+ and triple negative groups. Ki-67 and histological grade were higher in HER2+ group, significantly. Two deaths were triple negative (P=0.04). Androgen receptor-negativity, CK5/6 and Ki-67 status did not affect survival or systemic metastases, significantly. All groups had local recurrences. Local recurrence was significantly associated with androgen receptor-negativity in luminal A and high Ki-67 value in HER2+ groups. Systemic metastases were significantly more common in triple negative and HER2+ groups. CONCLUSION: Molecular subtypes of breast cancer are prognostic and predictive. Androgen receptor is expressed more commonly in luminal subtypes with better prognosis and androgen receptor negativity is associated with development of local recurrence in luminal A cancers.

Remission of ulcerated necrobiosis lipoidica diabeticorum after bariatric surgery.

A 32-year-old woman with type 2 diabetes mellitus suffering from morbid obesity with BMI 45,14 kg/m(2) was operated on. Not only the type 2DM but also one of its complication known as necrobiosis lipoidica diabeticorum remitted postoperatively. Obesity should no longer be regarded simply as a cosmetic problem affecting certain individuals but an epidemic that threatens global well-being. It causes or exacerbates many health problems, and in particular, it is associated with the type 2 diabetes. Necrobiosis lipoidica is a granulomatous skin disease of unknown etiology, associated mainly with diabetes mellitus. We presented in this paper a morbid obese case of necrobiosis lipoidica diabeticorum with dramatic good response to bariatric surgery.

Recurrent trichobezoar due to trichophagia: a case report.

OBJECTIVE: Trichobezoar, a hair ball in the gastrointestinal tract, is usually the result of the urge to pull out one's own hair (trichotillomania) and swallow it (trichophagia). It is almost exclusively seen in young females and may cause serious medical complications. This case report will describe an adult female patient with recurrent trichobezoars. METHOD: Data for this case report was collected from peer-reviewed literature and treatment encounters by the consultation-liaison psychiatry unit; subsequent to obtaining informed consent. RESULTS: The personality characteristics, familial structure and domestic stress found in this case mirror the literature. We initiated behavioral interventions including habit reversal training and patient education in combination with pharmacologic therapy with clomipramine. CONCLUSION: Left untreated, trichophagia can cause a life-threatening emergency, requiring surgery. Recurrence of tichobezoars can be anticipated when the underlying emotional disorder is not addressed using multimodal management including psychiatric evaluation and treatment combined with surgical procedures.

Routine use of positron-emission tomography/computed tomography for staging of primary colorectal cancer: does it affect clinical management?

BACKGROUND: The use of positron emission tomography-computed tomography (PET/CT) for the preoperative staging of patients with colon and rectal cancer has increased steadily over the last decade. The aim of this study was to evaluate the effect of PET/CT on the preoperative staging and clinical management of patients with colorectal cancer. METHODS: Between December 2010 and February 2012, 64 consecutive patients with colorectal cancer were evaluated with both PET/CT scans and conventional preoperative imaging studies. We prospectively recorded the medical reports of these patients. The PET/CT findings were compared with conventional imaging studies and the rate of over-staging or down-staging and changes in clinical management were evaluated. The correlation of the PET/CT with the conventional imaging was compared by a kappa agreement coefficient. Differences in the accuracy for N and T staging were assessed by χ2 and related-samples marginal homogeneity tests. RESULTS: Thirty-nine (60.9%) patients had rectal cancer and 25 (39.1%) had colon cancer. Based on PET/CT, additional lesions were found in 6 (9.4%) of the patients: hilar and paratracheal lesions in 4 patients, hepatic in 1 and supraclavicular in 1 patient. In four of six patients, detailed imaging studies or biopsies revealed chronic inflammatory changes. Hepatic and supraclavicular involvement was confirmed in two patients. Therefore, the false positivity rate of PET/CT was 6.25%. Based on the additional PET/CT, 2 (3.2%) patients had a change in surgical management. A chemotherapy regimen was administered to the patient with a 1.5 cm hepatic metastasis near the right hepatic vein; for another patient with an identified supraclavicular lymph node metastasis, a simultaneous excision was performed. CONCLUSIONS: Routine use of PET/CT for preoperative staging did not impact disease management for 96.8% of our patients. The results of our study conclude that PET/CT should not be routinely used for primary staging of colorectal cancer. More studies are required for identifying the subgroup of patients who might benefit from a PET/CT in their initial staging.

Ischemia modified albumin can predict necrosis at incarcerated hernias.

PURPOSE: To evaluate the predictive effect of IMA in incarcerated hernias. METHODS: Three groups (n = 7) of rats were operated. Group I aimed to mimic incarceration, group II aimed the strangulation, and group III was the sham group. IMA and LDH measurements were made. RESULTS: IMA levels were significantly higher in strangulation mimicking group and IMA levels were normal at postoperative 6th hour in incarceration mimicking group. LDH levels were significantly higher in both incarceration and strangulation mimicking groups. CONCLUSION: IMA seems to be an effective marker in incarcerated hernias to predict necrosis. But we need further studies to generalise this hypothesis.

Perforated gastrointestinal stromal tumor in the jejunum: A rare cause of acute abdomen.

Gastrointestinal stromal tumors (GIST) are highly frequent mesenchymal tumors of the digestive tract, which mainly affect the stomach and small intestine. GISTs frequently exist with unclear symptoms. Their initial clinical presentation as acute abdomen due to their perforation is particularly rare. In the present study we report a case of a 59-year-old male presenting with acute abdomen. The final diagnosis revealed a small bowel perforation due to GIST. In this paper, we report the clinical manifestation as well as computed tomography and histopathological findings helpful for the accurate diagnosis of this rare complication of GIST. Emergency laparotomy and complete resection of tumor are essential. Following surgical resection, adjuvant tyrosine kinase inhibitor therapy should be considered for prevention of early recurrence.

Intersphincteric resection and coloanal anastomosis in treatment of distal rectal cancer.

In the treatment of distal rectal cancer, abdominoperineal resection is traditionally performed. However, the recognition of shorter safe distal resection line, intersphincteric resection technique has given a chance of sphincter-saving surgery for patients with distal rectal cancer during last two decades and still is being performed as an alternative choice of abdominoperineal resection. The first aim of this study is to assess the morbidity, mortality, oncological, and functional outcomes of intersphincteric resection. The second aim is to compare outcomes of patients who underwent intersphincteric resection with the outcomes of patients who underwent abdominoperineal resection.

Laparoscopic cholecystectomy and postoperative pain: is it affected by intra-abdominal pressure?

BACKGROUND AND PURPOSE: Intra-abdominal pressure created during laparoscopic cholecystectomy is accepted as a factor for postoperative pain. In this prospective, randomized, clinical study, the goal is to determine the effects of different intra-abdominal pressure values on visceral type pain. MATERIALS AND METHODS: Sixty women who underwent laparoscopic cholecystectomy were included in this study. Low-pressure (8 mm Hg), standard-pressure (SP: 12 mm Hg), and high-pressure (HP: 14 mm Hg) groups were designed for the study. The statistical analysis included mean age, weight, analgesic consumption, postoperative pain assessed by the Numeric Scale, duration of anesthesia, and operation. RESULTS: No statistically significant difference was found between the groups comparing age, weight, analgesic consumption, and Numeric Scale values. In terms of duration of anesthesia, statistically significant difference was found between the groups low-pressure and HP and SP and HP, and statistically significant difference was found regarding operative duration between the groups SP and HP. There was no difference between the others groups. CONCLUSIONS: We think that intra-abdominal pressure has no effect on postoperative visceral pain, but has effect on duration of anesthesia and operation.

Corticosteroid treatment and timing of surgery in idiopathic granulomatous mastitis confusing with breast carcinoma.

Idiopathic granulomatous mastitis (IGM) is an uncommon chronic inflammatory lesion of the breast with an uncertain optimal treatment regimen, the physical examination, and radiologic features of which may be confused with breast carcinoma. In this study, we aimed to describe the clinicopathologic characteristics of 33 patients who admitted to our breast policlinic and took the diagnosis of granulomatous (idiopathic and non-idiopathic) mastitis, and report the place of corticosteroids and the timing of surgery in the treatment of patients with IGM. The clinical features of 33 patients who presented to our breast policlinic with the complaint of breast mass and reached the final diagnosis of GM between March 2005 and October 2009 were reported. The most common symptoms were mass (n: 27) and pain (n: 11). Ultrasonography (USG) and biopsy were performed in all of the patients. Mammography (MMG) was performed in 9, and magnetic resonance imaging (MRI) in 10 patients. The diagnosis of idiopathic lobular granulomatous mastitis (ILGM) was made in 25 patients and tuberculous mastitis (non-idiopathic GM) in the remaining 8 patients. Twenty-four patients received steroid treatment except one who was pregnant. After giving birth, she also received steroids. One of the patients who developed recurrence after 11 months repeated the steroid therapy. Eight patients with tuberculous mastitis were placed on a regimen of antituberculosis therapy for 6 months. In the diagnosis of IGM, physical examination, USG, MMG, and even MRI alone may sometimes not be enough. They should be discussed altogether and the treatment should begin after definitive histopathologic result. Fine needle aspiration biopsy for cytology will result in a high level of diagnostic accuracy, however, core biopsy will reinforce the exact result. Corticosteroid therapy has been shown to be efficacious for IGM, but in the existence of complications such as abscess formation, fistulae, and persistent wound infection, surgical treatment has been the first method of choice.

Impact of slit and nonslit mesh technique on testicular perfusion and volume in the early and late postoperative period of the totally extraperitoneal preperitoneal technique in patients with inguinal hernia.

AIMS: Using slit and nonslit mesh in laparoscopic totally extraperitoneal preperitoneal (TEPP) inguinal hernia repair are well-known approaches. The aim of this prospective, randomized, clinical study was to assess testicular perfusion after these procedures. METHODS: In the study period, 40 male patients with unilateral inguinal hernia were assigned into 2 equal groups as follows: slit (S) and nonslit (NS). TEPP hernia repair was performed in all patients. In the 2 groups, testicular arterial blood flow and testis volumes were measured by Doppler ultrasonography preoperatively, on the 5th postoperative day, and 6 months postoperatively, respectively. RESULTS: No statistically significant difference was found between the preoperative, 5th day postoperatively, and 6-month arterial resistance index (ARI) results when comparing the S and NS groups in ultrasonographic testicular blood flow studies. There was no statistically significant difference of testicular volume between the preoperative period, the 5th postoperative day, and 6 months postoperatively in the 2 groups. CONCLUSIONS: According to the results, no statistically significant difference was found in terms of testicular perfusion and volume between those 2 methods of TEPP repair for inguinal hernia.

[Evaluation of percutaneous endoscopic gastrostomy and results]. / Perkütan endoskopik gastrostomi ve sonuçlarinin degerlendirilmesi.

BACKGROUND: The aim of this study is evaluate the percutaneous endoscopic gastrostomy (PEG) and its complications in order to provide enteral nutrition support for a long time period. METHODS: PEG tube was applied to 15 patients aged between 18-95 years, who could not feed orally prophylactic antibiotic didn't use to any patient. After 8 hours hungry PEG was applied by using pull technique and the results were evaluated prospectively. RESULTS: PEG was successfully done in 14 patients. Gastric juice drainage at the sides of the tube were seen in two patients, and PEG was pulled out in one of them. CONCLUSIONS: PEG is the route of choice for a long lived enteral nutrition, because, it can be applied without general anesthesia, easy to apply, patients can start feeding in a short time period, need shorter hospital stay, can be changed easily, cost effective and has a low rate of mortality and morbidity.
