The Effect of Combined Spinal Epidural Anesthesia on Shoulder Pain in Laparoscopic Extraperitoneal Hernia Surgery.

BACKGROUND: Shoulder pain is a condition that seriously discomforts patients and develops caused by a peritoneal tear in laparoscopic extraperitoneal hernia repair (TEP) surgeries. Although surgeons generally prefer general anesthesia for the TEP technique, many studies have been carried out on the use of regional anesthesia in recent years. In our study, we aimed to investigate the efficacy and safety of the combined spinal/epidural anesthesia (CSEA) method to prevent shoulder pain in the TEP technique. METHODS: The patients who operated with the TEP procedure were divided into 2 groups; SA (group 1) and CSEA (group 2). The 2 patient groups were compared in terms of sex, age, body mass index, duration of surgery, total operation time, patient satisfaction, pain scores, length of hospital stay, adverse effects, intraoperative, and postoperative complications. RESULTS: The number of patients in group 1 was 42 and group 2 was 40. The mean operation time was recorded as 55.9 and 80.2 minutes in groups 1 and 2, respectively, which was statistically significantly shorter in group 1 (P<0.001). Postoperative pain was significantly less in group 2 for the 4th hour (P<0.0001) and the 12th hour (P=0.047). There was no difference between the 2 groups in terms of peritoneal tear (P=0.860). Intraoperative and postoperative shoulder pain was significantly less in group 2 (P=0.038, P=0015, respectively). CONCLUSION: CSEA is an effective and safe anesthesia method for preventing shoulder pain that develops after TEP surgeries.

Accuracy of the ACS NSQIP Surgical Risk Calculator for Predicting Postoperative Complications in Gastric Cancer Following Open Gastrectomy.

INTRODUCTION: The prediction of complications before gastric surgery is of utmost importance in shared decision making and proper counseling of the patient in order to minimize postoperative complications. Our aim was to evaluate the predictive validity of American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) risk calculator in gastric cancer patients who underwent gastrectomy. METHODS: Preoperative assessment data of 432 patients were retrospectively reviewed and manually entered into the calculator. The accuracy of the calculator was evaluated using Pearson's chi-squared test, C-statistic, Brier score, and Hosmer-Lemeshow test. RESULTS: The lowest Brier scores were observed in urinary tract infection, renal failure, venous thromboembolism, pneumonia, and cardiac complications. Best results were obtained for predicting sepsis, discharge to rehabilitation facility, and death (low Brier scores, C-statistic >.7, and Hosmer-Lemeshow P > .05). CONCLUSION: The calculator had a strong performance in predicting sepsis, discharge to the rehabilitation facility, and death. However, it performed poor in predicting the most commonly observed events (any or serious complication and surgical site infection).

Is the serum level of survivin, an antiapoptotic protein, a potential predictive and prognostic biomarker in metastatic pancreatic cancer?

In the present study, we aimed to assess the association between the serum survivin level and overall survival and treatment response rates in metastatic pancreatic cancer (MPC). Serum samples were prospectively collected from 41 patients with newly diagnosed MPC patients and 41 healthy individuals (control group) to assess the survivin levels. The median survivin level was 136.2 ng/mL in patients with MPC and 52 ng/mL in healthy individuals (P = .028). Patients were divided into low- and high-survivin groups according to the baseline median survivin level. Patients with a high serum survivin level compared with a low serum survivin level had shorter median progression-free survival (2.39 vs 7.06 months; P = .008, respectively) and overall survival (3.74 vs 9.52 months; P = .026, respectively). Patients with higher serum survivin levels had significantly worse response rates (P = .007). The baseline high level of serum survivin in patients with MPC may be associated with treatment resistance and poor prognosis. A confirmation will be needed for these results in future large multicenter prospective studies.

Idiopathic granulomatous mastitis: introducing a diagnostic algorithm based on 5 years of follow-up of 152 cases from Turkey and a review of the literature.

PURPOSE: The goals of this study were to report our clinical experience in a single center at a high-volume tertiary university hospital in Istanbul and to introduce a diagnostic algorithm based on a 5-year follow-up of 152 women with biopsy-proven idiopathic granulomatous mastitis (IGM). IGM is an uncommon, non-malignant, chronic inflammatory disease of the mammary gland with an unknown etiology. The symptoms, clinical presentation, and radiologic findings of IGM may resemble carcinomas. To our knowledge, this study comprises the largest series of IGM, especially with a 5-year follow-up, yet reported in the English literature. METHODS: The present study reported our single-center clinical experience at a tertiary university hospital in Istanbul, Turkey, and introduced a diagnostic algorithm using our treatment protocol based on a 5-year follow-up of 152 women with biopsy-proven IGM. Our database of 10 years' experience containing over 700 patients with IGM was evaluated. However, to assess recurrence and resistance to treatment, only the 152 patients with a long follow-up period of 5 years were included in the study group. The analysis included 152 women with biopsy-proven IGM who were treated between January 2009 and March 2014. The clinical data of the presentation, histopathology, and treatment modalities were analyzed by reviewing the medical records. RESULTS: Of the 152 patients diagnosed with granulomatous mastitis, 32 (21%) recovered by expectant management, while 14 (9%) responded to antibiotics, 65 (43%) received corticosteroids, 20 (13%) had antituberculosis medication, 16 (11%) underwent excision, and 5 (3%) responded to non-steroidal anti-inflammatory drugs. Fifty-one patients (33%) had recurrence; of these, 30 achieved a cure with second-line treatment, 16 underwent excision, and 5 achieved a cure with observation. CONCLUSION: IGM is a rare benign breast disorder, and clinicians need a high index of suspicion to diagnose it, as IGM can be mistaken for breast cancer. Unlike periductal mastitis, IGM does not evolve secondary to nicotine addiction and is typically seen in women of childbearing age with a recent history of pregnancy and lactation. The diagnosis can be challenging, and an evaluation with a multidisciplinary team is necessary. There is no consensus concerning the definitive treatment approach. We suggested a diagnostic algorithm in the present study, using our treatment protocol based on the 5 years' follow-up of 152 women.

Fournier's gangrene: Five years' experience from a single center in Turkey.

BACKGROUND: Is the present study aims to analyze demographic, clinical and surgical data of all patients with FG (Fournier's gangrene) admitted to a tertiary healthcare hospital in the largest city of Turkey. METHODS: This study included 35 patients with Fournier's gangrene, who were followed by the General Surgery, Plastic Surgery, and Urology Departments of Istanbul University Cerrahpasa Faculty of Medicine from January 2010 to January 2015. Demographic and clinical data, including gender, age, length of stay at the hospital, the underlying cause(s), number of debridement, predisposing factors, and surgical reconstructive data over 10 years were assessed and analyzed retrospectively. RESULTS: The mean age of the 35 patients was 58.14±12.71 years. Diabetes mellitus was present in 20 of the 35 (57.1%) patients. Twelve of the patients (34.2%) were hospitalized in the intensive care unit (ICU). Length of stay in the ICU was found to be significantly influenced by age, hematocrit level, FGSI and UFGSI (p=0.013, p=0.030 p=0.025 and p=0.002, respectively). CONCLUSION: Fournier's gangrene is a fulminant infection with a high mortality rate. Physical examination and anamnesis are quite important for the diagnosis of FG. DM is the most common comorbidity. Age, hematocrit level, FGSI and UFGSI scores affect the patients' length of stay in the ICU.

Foreign body: A sewing needle migrating from the gastrointestinal tract to pancreas.

Of all ingested foreign bodies, 2.4% comprise of sewing needles. Through perforation of gastrointestinal tract, which occurs in 1% of cases, they can migrate into the liver and pancreas. Foreign bodies in pancreas should be considered in the differential diagnosis of chronic abdominal pain. Computed tomography scans provide valuable information for the localization of the lesion, which guide the surgeon during the operation. Secondary to foreign bodies that migrate to the pancreas, complications with high mortality such as pancreatitis, pseudoaneurysm, and pancreas abscess can be seen. Thus, for this patient group, diagnostic laparoscopy is recommended, considering its advantages of decreased postoperative pain, decreased wound infection, and faster recovery time. Here we present a case of a 23-year-old female patient, from whom an ingested needle that migrated from the back wall of the stomach to the pancreas was extracted by laparoscopic surgery.

Spinal/epidural block as an alternative to general anesthesia for laparoscopic appendectomy: a prospective randomized clinical study.

INTRODUCTION: Laparoscopic appendectomy (LA) has been generally performed under general anesthesia. Laparoscopic appendectomy is rarely performed under regional anesthesia because of pneumoperitoneum-related problems. AIM: To compare spinal/epidural anesthesia (SEA) and general anesthesia (GA) during LA with respect to perioperative and postoperative adverse events and postoperative pain. MATERIAL AND METHODS: Fifty patients, aged 18-65, who underwent LA, were randomly allocated to two groups: the GA (n = 25) and SEA (n = 25) groups. Perioperative and postoperative adverse events, postoperative pain level, and patient satisfaction were compared between the groups. RESULTS: None of the patients needed conversion to an open procedure or conversion from SEA to GA. In the SEA group we encountered shoulder pain in 6 (24%) patients, abdominal discomfort/pain in 4 (16%) patients, anxiety in 4 (16%) patients, and hypotension in 2 (8%) patients intraoperatively. Also, post-spinal headache was observed in 5 (20%) patients in the SEA group. Postoperative right shoulder pain was significantly higher in the GA group compared to the SEA group (32% vs. 8%; p = 0.037). In the SEA group the incidence of urinary retention and in the GA group the incidence of postoperative nausea and vomiting (PONV) were higher, but these differences were not statistically significant. The postoperative surgical pain level was significantly lower in the SEA group (p < 0.001). CONCLUSIONS: Spinal/epidural anesthesia is effective and safe in ASA I healthy patients undergoing LA. Less postoperative pain, PONV and shoulder pain are the advantages of SEA compared to GA.

Rare case of bilateral incarcerated obturator hernia: a case report.

Here, we report the case of an 84-year-old woman with acute mechanical intestinal obstruction (AMIO) who was admitted to our Emergency Department. Computed tomography (CT) scan revealed an incarcerated bilateral obturator hernia, and the defect was resolved using transabdominal preperitoneal (TAPP) technique with polypropylene mesh. The patient was administered an oral regimen two days after the operation. The patient stayed in the intensive care unit for 4 days and was uneventfully discharged on the 9th postoperative day. Follow-up was scheduled at the 6th month, during which no adverse events were detected and the patient did not report any complaints. Obturator hernia is among the differential diagnoses of intestinal obstruction requiring early diagnosis and prompt surgical intervention. Laparoscopic approach is less invasive compared with open surgery, and it can be attempted in cases presenting with no sign of ischemia or peritonitis. TAPP technique should be preferred since it allows the control of all intraabdominal pathologies and the viability of the intestines.

Extragastrointestinal Stromal Tumor (EGIST): A 16-Year Experience of 13 Cases Diagnosed at a Single Center.

BACKGROUND Gastrointestinal stromal tumor (GISTs) rarely occurs outside the GI tract as extragastrointestinal stromal tumor (EGIST). The aim of this study was to review the clinical presentation, diagnosis, and outcome of EGIST at a single center. MATERIAL AND METHODS The study was a retrospective study performed at Istanbul University Hospital in a 16-year period and included patients with a histopathological diagnosis of EGIST confirmed to arise outside the GI tract. The patients' available medical records included patient demographics, imaging and surgical data, and diagnostic histopathology reports. Cases of EGIST underwent follow-up for several years and the medical files of patients were well maintained. RESULTS Thirteen cases of EGIST included six women and seven men, with a mean age of 59.6 years (range, 33-83 years). Eleven patients had EGISTs located in the intra-abdominal cavity, one patient's tumor was in the retroperitoneum, and in the jejunal mesentery in one patient. The mean diameter of the EGISTs was 15.6 cm (range, 4-30 cm). Immunohistochemistry showed that all cases were negative for desmin, with positive immunostaining for CD34 (n=6), smooth muscle actin (SMA) (n=3), and Ki67 (n=6), without specific diagnostic markers. Following surgical resection, tumor recurrence occurred in three patients, and metastasis in two patients. The mean overall survival (OS) was 45.66 months (56.44 months for women; 32.57 months for men); the 5-year survival rate of our patients was 38%. CONCLUSIONS EGIST presented with a large tumor size at diagnosis, was mainly intra-abdominal, and had a low mean patient survival time with no specific diagnostic tissue immunomarkers.

Can volumetric measurement be used in the selection of treatment for inguinoscrotal hernias?

OBJECTIVE: Inguinoscrotal hernias are often qualified subjectively as big, giant, scrotal, etc. In order to classify this type of hernia, objective criteria are needed. For this purpose, we aimed to introduce a scrotal volume measurement-based classification system and propose a corresponding surgical plan (open or laparoscopic surgery, anterior or posterior repair) based on volumetric data. MATERIAL AND METHODS: Between October 2012 and October 2013, 30 consecutive male patients with a mean age of 59.5 years (range: 36 to 82 years) presenting with unilateral ISH were included in this retrospective study. Physical measurements in the upright position and computerized tomography measurements using the Valsalva maneuver were obtained from all patients. RESULTS: Of the 30 patients, 26 patients had scrotal volumes less than 1000 mL, two patients had SVs between 1001 and 2000 mL, one patient had an SV between 2001 and 3000 mL, and one patient had an SV greater than 3000 mL. Laparoscopic total extraperitoneal repair was performed in patients with scrotal volumes inferior to 1000 mL. In three patients with scrotal volumes between 1000 and 3000 mL, an open posterior approach was used. In one patient with a scrotal volume superior to 3000 mL, no surgical intervention was performed due to the patient's cardiac comorbidity. CONCLUSION: By establishing a common language among surgeons, we believe that the volumetric measurement-based scrotal hernia classification system proposed in this study will lead to further studies on the subject.

Gastrointestinal stromal tumors: 16 years' experience within a university hospital.

AIM: the aim was to convey our 16-year experience regarding gastrointestinal stromal tumors within in a high volume university hospital. Factors that may impact on patient survival were evaluated. MATERIAL AND METHODS: all patients diagnosed with gastrointestinal stromal tumors in our clinic over a 16-year period were retrospectively evaluated. All patients included in the study had their tumors surgically resected. Survival analyses were performed using the Kaplan-Meier method. Survival time comparisons between groups were performed using the log-rank test. The effect of continuous variables on survival times were evaluated via a Cox-regression analysis with a backward conditional method. RESULTS: one hundred and thirty-five patients (76 males and 59 females) were included into the study and the mean age was 62.8 ± 13.3 years. Overall survival time was 121.3 ± 7.0 months and the 5-year survival rate was 66.6 ± 4.2%. Patients with colorectal tumors had significantly lower survival times than patients with tumors located in the stomach (p = 0.001) and small intestine (p = 0.033). Patients with moderate risk scores had a significantly longer survival compared to patients with high risk scores (p = 0.003) and patients with tumor recurrence had a significantly shorter survival (p < 0.001). There was no significant relationship between survival and factors such as gender and tumor size (p > 0.05). However, age, Ki-67 and the mitotic index were poor prognostic factors and C-kit was considered as a good prognostic factor. CONCLUSION: some of the findings in this study are consistent with published data. However, our data significantly differs from previous studies such as the common finding of the effect of gender and tumor size on survival.

Endoscopic diagnosis and treatment of biliary obstruction due to acute cholangitis and acute pancreatitis secondary to Fasciola hepatica infection.

In the differential diagnosis of biliary obstruction with unknown etiology, biliary fascioliasis should be considered in endemic and nonendemic regions. After diagnostic evaluation, endoscopic retrograde cholangiopancreatography (ERCP) was performed for etiological evaluation and/or treatment of biliary obstruction in five patients with a mean age of 55.8 years. Endoscopic sphincterotomy and cholangiogram revealed linear filling defects in the biliary system. Fasciola hepatica parasites were extracted using balloon and basket catheters in two and three patients, respectively. No morbidity or mortality was observed. F. hepatica infection should be considered as a differential diagnosis of biliary obstruction with unknown etiology in endemic and non-endemic regions. ERCP can be the standard diagnostic and/or therapeutic procedure in cases of biliary obstruction due to fascioliasis. Due to slippery and gel-like characteristics of the parasite, use of a basket catheter in semi-opened position may be required in case of unsuccessful extraction using a balloon catheter.

Comparison of the effects of spinal epidural and general anesthesia on coagulation and fibrinolysis in laparoscopic cholecystectomy: a randomized controlled trial: VSJ Competition, 2nd place.

INTRODUCTION: Laparoscopic cholecystectomy (LC) is usually performed under general anesthesia. Recently, laparoscopic cholecystectomy under regional anesthesia has become popular, but this creates a serious risk of thromboembolism because of pneumoperitoneum, anesthesia technique, operative positioning, and patient-specific risk factors. AIM: This randomized controlled trial compares the effects of two different anesthesia techniques in laparoscopic cholecystectomy on coagulation and fibrinolysis. MATERIAL AND METHODS: This randomized prospective study included 60 low-risk patients with deep vein thrombosis (DVT) who underwent elective LC without thrombo-emboli prophylaxis. The patients were randomly divided into two groups according to the anesthesia technique: the general anesthesia (group 1, n = 30) and spinal epidural anesthesia (group 2, n = 30) groups. Measurement of the prothrombin time (PT), thrombin time (TT), international normalized ratio (INR), activated partial thromboplastin time (aPTT), and blood levels of D-dimer (DD) and fibrinogen (F) were recorded preoperatively (pre), at the first hour (post 1) and 24 h (post 24) after the surgery. These results were compared both between and within the groups. RESULTS: The mean age was 51.5 ±16.7 years (range: 19-79 years). Pneumoperitoneum time was similar between group 1 (33.8 ±7.8) and group 2 (34.8 ±10.4). The TT levels significantly declined postoperatively in both groups. The levels of PT, aPTT, INR, D-dimer and fibrinogen dramatically increased postoperatively in both groups. CONCLUSIONS: While there was not any DVT, there was a significant decline in TT. There was a dramatic rise in the PT, INR, D-dimer, fibrin degradation products (FDP), and fibrinogen following LC. This may be attributed to the effects of pneumoperitoneum and anesthesia techniques on portal vein flow.

Predicting Value of Serum Procalcitonin, C-Reactive Protein, Drain Fluid Culture, Drain Fluid Interleukin-6, and Tumor Necrosis Factor-α Levels in Anastomotic Leakage after Rectal Resection.

BACKGROUND: Anastomotic leak is the most dreaded septic complication of colorectal surgical procedures. Death is proportional to the time between occurrence and diagnosis of the leakage. Biomarkers, which may help to predict anastomotic leakage before appearance of its clinical features, may be beneficial in preventing adverse outcomes. This study investigates a biomarker that might be useful to predict rectal anastomotic leakage before its clinical presentation. PATIENTS AND METHODS: Serum procalcitonin and C-reactive protein (CRP) levels, bacterial proliferation, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels of drain fluid were evaluated in 50 consecutive patients who underwent low anterior resection without diverting ostomy for rectal carcinoma. RESULTS: Anastomotic leakage occurred in seven of 50 (14%) patients. Serum CRP and procalcitonin levels at post-operative day three were higher in patients with anastomotic leakage (p = 0.01, p = 0.02 respectively). Drain TNF-α values were increased 63.2% on post-operative day five when compared with post-operative day three in patients with anastomotic leakage, but were decreased in patients without leakage. There was no statistical difference for drain IL-6 levels between groups. The bacterial proliferation rate of drain fluid culture in the leakage group was 42.9% at post-operative day three and 85.7% at post-operative day five (p = 0.29 and p = 0.0001, respectively). CONCLUSIONS: High serum CRP and procalcitonin values on post-operative day three are alarming, and assessment of anastomotic leakage by abdominal imaging with rectal contrast is suggested. In addition, increasing levels of TNF-α and bacterial proliferation in drain fluid are predictive, whereas IL-6 is not.

New advantageous tool in single incision laparoscopic cholecystectomy: the needle grasper.

INTRODUCTION: During single-incision laparoscopic cholecystectomy (SILC), the gallbladder is suspended with stitches, resulting in perforation risk and difficulty in exploration. AIM: We used the needle grasper in SILC to hang and manipulate the gallbladder. MATERIAL AND METHODS: Sixty-five patients (43 female, 22 male) who underwent SILC between December 2013 and December 2014 were analyzed retrospectively for patient demographics, duration of operation, laparotomy or conventional laparoscopy necessity, drain use, complications, and hospital stay periods. To place the SILC port (Covidien, Inc.), the needle grasper was inserted at the right upper abdominal quadrant without an incision to hang and manipulate the gall-bladder. RESULTS: The mean age was 47.9 ±13.068 years; the mean body mass index (BMI) was 26.94 ±3.913 kg/m2. ASA scores were 1, 2, and 3. Two patients with high BMI with additional trocar use were excluded. The operations were completed without any additional trocar in 59 patients. The mean operation time was 89 ±22.41 min. Eighteen patients required a drain; all were discharged after drain removal. One patient needed re-hospitalization and percutaneous drainage and was discharged on the 9th day. Fifty-three patients were discharged on the 1st post-operative day. Eleven patients with drains were discharged on the 2nd day, and 1 was discharged on the 7th day. The mean hospital stay period was 1.26 ±0.815 days. CONCLUSIONS: The main difficulty of SILC is to manipulate hand tools because the triangulation principle of laparoscopy use is not possible in SILC. Inserting a needle grasper into the abdominal cavity at the right subcostal area to manipulate the gallbladder helps and does not leave a visible scar.
