Analyzing the Role of Anal Sphincter Pressure in Rectocele Formation.

PURPOSE: Constipation is a common entity in society with various factors in the etiology. In this study, we evaluated the role of anal sphincter pressure of patients who refer to surgery clinic with complaint of constipation. METHODS: Sixty patients who refer to surgery clinic with complaint of constipation and were diagnosed with constipation due to Rome III criteria between July 2010 and September 2014. These patients were evaluated with defecography and were divided into 2 groups based on presence of rectocele. Both groups' anal sphincter pressures were evaluated using anal manometry and findings were compared. RESULTS: The patients with rectocele and without rectocele using defecography were inspected with anal manometry regarding resting tone pressure, squeeze pressure, maximum squeeze pressure and simulated defecation response pressure, first sensation volume, urge sensation volume, and maximum tolerable volume. Results were compared and no significant difference was found regarding groups with rectocele and without rectocele (P > 0.05). CONCLUSION: We have proved the hypothesis arguing that increased sphincter pressures do not play a role in the formation of rectocele by inducing an obstruction and the formation of dilation in proximal bowel, and demonstrated that the presence of rectocele is not dependent on an increase in sphincter pressures.

Prevention of Postoperative Bile Leak in Partial Cystectomy for Hydatid Liver Disease: Tricks of the Trade.

BACKGROUND: The presence of postoperative bile leak is the major outcome measure for the assessment of operative success in partial cystectomy for hydatid liver disease. However, the optimal operative strategy to reduce the postoperative bile leak rate is yet to be defined. METHODS: Medical records of patients who underwent partial cystectomy for hydatid liver disease between January 2013 and January 2015 were reviewed in this retrospective analysis. All patients were managed with a specific operative protocol. The primary outcome measure was the rate of persistent postoperative bile leak. The secondary outcome measures were the morbidity and mortality rate, and the length of hospital stay. RESULTS: Twenty-eight patients were included in the study. Only one patient (3.6 %) developed persistent postoperative bile leak. The overall morbidity and mortality rate was 17.8 and 0 %, respectively. The median length of hospital stay was 5 days. CONCLUSION: Aggressive preventative surgical measures have led to low persistent bile leak rates with low morbidity and mortality.

Giant juvenile fibroadenoma.

Juvenile fibroadenoma is a common cause of breast masses seen in adolescents and young women. Giant juvenile fibroadenomas are usually single and unilateral. The etiology is thought to be due to increased levels of estrogen during adolescence, although it is not yet fully understood. Treatment options range from simple excision to sub-cutaneous mastectomy according to the size of the lesion. This article aimed to present a case that was diagnosed with "giant juvenile fibroadenoma".

The adaptation process of a teaching and research hospital to changing trends in modern breast surgery.

OBJECTIVE: Minimally invasive surgery is increasingly gaining importance in breast surgery parallel to other surgical branches. Sentinel lymph node biopsy (SLNB) is a method that has radically changed the approach to breast surgery in the last decade of the 20(th) century. In this study, we aimed to evaluate the adaptation process to these alterations in breast surgery at our clinic. MATERIAL AND METHODS: Patients who underwent surgery with a diagnosis of breast cancer in our clinic between April 2010 and November 2013 were retrospectively evaluated in terms of demographic characteristics, the number of operations and type of surgical methods applied according to years, SLNB performance rate, and results of frozen section and histopathological analysis. The first year of SLNB practice was accepted as part of the learning curve, and 24 patients who were operated during that period underwent routine axillary dissection. RESULTS: The median age of 198 patients who were included in the study was 55 years (25-89). It was detected that the number of cases who underwent surgery for breast cancer increased in years, that the SLNB application rate increased from 37% to 66% between 2010 and 2013 (p=0.01), and SLNB staining rates increased from 70% to 94% (p=0.03). When only results from the last four years were evaluated, the mean staining rate in patients with SLNB (n=105) was 88% (n=92), with positive histopathology in 32% of these cases (n=30). Despite a decreasing trend over the years, a metastatic axillary lymph node was detected in paraffin block evaluation in spite of negative frozen section examination of SLNB in five cases, and 5 patients (5%) out of 97 patients who underwent breast conserving surgery required re-excision. The histopathological diagnosis was invasive ductal carcinoma in 84% (n=167) of patients. CONCLUSION: It was observed that during the four-year period of adaptation, the application rate of breast conserving surgery and SLNB reached accepted standards, and that both the technical problems encountered in SLNB and the requirement for re-excision after breast conserving surgery significantly decreased with increasing case volume and experience.

Evaluation of the Probability of Non-sentinel Lymph Node Metastasis in Breast Cancer Patients with Sentinel Lymph Node Metastasis using Two Different Methods.

OBJECTIVE: The aim of this retrospective clinical study was to evaluate the accuracy and feasibility of two different clinical scales, namely the Memorial Sloan-Kettering Cancer Center (MSKCC) nomogram and Tenon's axillary scoring system, which were developed for predicting the non-sentinel lymph node (NSLN) status in our breast cancer patients. MATERIAL AND METHODS: The medical records of patients who were diagnosed with breast cancer between January 2010 and November 2013 were reviewed. Those who underwent sentinel lymph node biopsy (SLNB) for axillary staging were recruited for the study, and patients who were found to have positive SLNB and thus were subsequently subjected to axillary lymph node dissection (ALND) were also included. Patients who had neoadjuvant therapy, who had clinically positive axilla, and who had stage 4 disease were excluded. Patients were divided into two groups. Group 1 included those who had negative NSLNs, whereas Group 2 included those who had positive NSLNs. The following data were collected: age, tumor size, histopathological characteristics of the tumor, presence of lymphovascular invasion, presence of multifocality, number of negative and positive NSLNs, size of metastases, histopathological method used to define metastases, and receptor status of the tumor. The score of each patient was calculated according to the MSKCC nomogram and Tenon's axillary scoring system. Statistical analysis was conducted to investigate the correlation between the scores and the involvement of NSLNs. RESULTS: The medical records of patients who were diagnosed with breast cancer and found to have SLNB for axillary staging was reviewed. Finally, 50 patients who had positive SLNB and thus were subsequently subjected to ALND were included in the study. There were 17 and 33 patients in Groups 1 and 2, respectively. Both the MSKCC nomogram and Tenon's axillary scoring system were demonstrated to be significantly accurate in the prediction of the involvement of NSLNs (p<0.05 for each). Among all the parameters, the only one that was found to be correlated with the risk of NSLN involvement was the presence of lymphovascular invasion. CONCLUSION: The MSKCC nomogram and Tenon's axillary scoring system both seem to be reliable tools for the assessment of NSLN status in SLNB-positive breast cancer in our breast cancer population. Nevertheless, the omission of ALNB in SLNB-positive breast cancer cannot be yet recommended because of the lack of long-term results of current nomograms and scoring systems.

Colonic stent as bridge to surgery in patients with obstructive left-sided colon cancer.

OBJECTIVE: We assessed the optimal time interval between endoscopic stenting and subsequent surgery in patients with obstructive left-sided colon cancer. METHODS: We reviewed the medical records of patients who underwent endoscopic colonic stenting for obstructive left-sided colon cancer between January 2009 and January 2012. Patients who had successful endoscopic intervention as a bridge to surgery were included in the study. Other variables studied were the duration between endoscopic stenting and surgery, the reobstruction rate, the stoma creation rate, the anastomotic leak rate, and the in-hospital mortality rate. RESULTS: The medical records of 53 patients who underwent endoscopic stenting for obstructive left-sided colon cancer were reviewed, and 43 were included in the study. The median duration between endoscopic stenting and surgery was 7 days (range, 5-33). CONCLUSION: A median duration of 7 to 9 days after endoscopic stenting in patients with obstructive left-sided colon cancer is enough time to subsequently perform a safe surgical procedure. Extending this duration may expose the patient to the risk of reobstruction and emergency surgery.

Two different methods for appendiceal stump closure: metal clip and Hem-o-lok clip.

INTRODUCTION: Closure of the appendiceal stump (CAS) is the most crucial part of appendectomy procedures because most of the complications occur by a leak of the stump. The aim of this retrospective clinical study is to emphasize two different methods (metal clip and Hem-o-lok(®) [Teleflex Medical, Research Triangle Park, NC] clip) for CAS. MATERIALS AND METHODS: The cases were divided into two subgroups according to the type of CAS. Subgroups were compared with each other according to age, intraabdominal abscess formation, operation duration, and complication rate. RESULTS: No intraoperative complications were seen in either subgroup. There were 22 postoperative complications in the metal clip subgroup (13 intraabdominal abscesses, 9 wound infections) and 8 postoperative complications in the Hem-o-lok clip subgroup (five intraabdominal abscesses, three wound infections). The cost of the closure was $7 for the metal clip group and $50 for the Hem-o-lok clip group. CONCLUSIONS: The use of Hem-o-lok clips and metal clip for CAS in laparoscopic appendectomy is a feasible, safe, and cost-effective procedure in patients with a mild to moderately inflamed appendix base of less than 10 mm in diameter.

Management of acute appendicitis in pregnancy.

BACKGROUND: Acute appendicitis is the most common surgical non-obstetric pathology during pregnancy. In this report, pregnant patients operated with a diagnosis of acute appendicitis in the last three years are evaluated retrospectively. METHODS: Between January 2009 and January 2011, 20 pregnant patients were operated for acute appendicitis. Patients were evaluated regarding age, gestational age, clinical and laboratory examinations, imaging studies, operative findings, mean hospital stay, mean operative time, and outcome. RESULTS: In 17 of 20 patients, acute appendicitis was confirmed and appendectomy was performed. Ten of the patients were operated with laparoscopic technique and the remaining 10 had open appendectomy. There was no fetal or maternal morbidity or mortality in any patient. All 20 patients delivered healthy babies during the postoperative course. CONCLUSION: Acute appendicitis is a challenging diagnosis in the pregnant patient; however, early surgical intervention should be performed with any suspicion. The type of surgery depends on the surgeon's preference and experience.

Prophylactic injection therapy is necessary for Forrest type 2b duodenal ulcers.

BACKGROUND: We aimed to assess the effect of prophylactic injection therapy during the index gastroscopy on upper gastrointestinal bleeding due to Forrest type 2b duodenal ulcer. METHODS: The patients who were admitted with upper gastrointestinal bleeding and who underwent emergency gastroscopy between January 2004 and January 2011 were recruited to the study retrospectively. Among those, the patients with Forrest type 2b duodenal ulcer were selected and divided into two groups. The patients in Group 1 had only diagnostic gastroscopy, whereas those in Group 2 had prophylactic injection therapy during the index gastroscopy. RESULTS: Eighty-seven patients were included in the study. There were 41 patients in Group 1 and 46 patients in Group 2. There was a significant difference in the incidence of rebleeding (26.8% versus 6.5%, p=0.017). The mortality rate was similar in the two groups (9.7% versus 2.1%, p=0.184). CONCLUSION: We recommend prophylactic injection therapy in patients with upper gastrointestinal bleeding who have Forrest type 2b duodenal ulcer.

Acute biliary pancreatitis related with pregnancy: a 5-year single center experience.

BACKGROUND: Pregnancy-associated acute biliary pancreatitis is a rare but challenging clinical entity in terms of diagnosis and management. We report our institutional medical data of pregnancy-associated acute biliary pancreatitis. METHODS: Medical records of 27 patients admitted to our clinics for pregnancy-associated acute biliary pancreatitis between January 2005 and January 2010 were reviewed. RESULTS: Of the 27 patients, 25 (93%) were in the post-partum period, and 2 (7%) were pregnant. Seventeen patients (63%) were managed with conservative treatment, and were scheduled for interval cholecystectomy, while 10 patients (37%) had early cholecystectomy prior to discharge. The mortality rate was 3% (n=1). CONCLUSION: Pregnancy-associated acute biliary pancreatitis usually has a mild-to-moderate clinical course with a favorable outcome, and can be managed successfully with conservative treatment. Early cholecystectomy done prior to discharge in the initial admission should be considered in mild-to-moderate pregnancy-associated acute biliary pancreatitis, except in patients within the first trimester.

Wandering spleen: Report of two cases.

Wandering spleen is a rare clinical condition which presents with a variety of symptoms with abdominal pain, abdominal mass, and acute abdomen. It may also remain silent until diagnosed by a routine imaging study. Treatment options may differ depending on the presenting clinical picture. Herein we present two cases of wandering spleen treated by splenectomy, with one of them admitted to our emergency clinic with torsion.

Comparison of operative and non operative management of acute appendicitis.

BACKGROUND: In this prospective study, operative and nonoperative management of acute appendicitis were evaluated regarding their safety and cost effectiveness. METHODS: Two hundred ninety patients presenting to our Emergency Department between March 2005 and March 2006 with acute appendicitis were included in this prospective study. Nonoperative medical therapy was performed in 107 patients (Group 1), and 183 patients were treated surgically (Group 2). Routine follow-up controls were done on the 10th day, at the 3rd and 6th months and at the first year after discharge in Group 1. Both groups were compared regarding age, gender, mean hospital stay, modified Alvarado score, morbidity, mortality, and cost effectiveness. RESULTS: The male/female ratio of Groups 1 and 2 were 65/42 (mean age: 30.98+/-1.30) and 125/58 (mean age: 26.25+/-0.79), respectively. In Group 1, 19 patients were operated. Operation indications were resistance to therapy, patient's request, and operation in another hospital. Although the mean hospital stay of Group 1 was statistically significantly longer than Group 2, the mean cost of the therapy was $559 in Group 2 and $433 in Group 1. Morbidity rates were similar, with no mortality in either group. CONCLUSION: With its high success rate and cost effectiveness, medical treatment seems to be a good alternative to the gold standard therapy of surgery in management of acute appendicitis.

Is endoscopic band ligation superior to injection therapy for Dieulafoy lesion?

BACKGROUND: Dieulafoy lesion is a rare but serious cause of gastrointestinal system bleeding. An aberrant submucosal artery, which was described in 1884, causes the bleeding. The lesion can be located anywhere in the gastrointestinal tract but is most commonly found in the proximal stomach up to 6 cm from the gastroesophageal junction. Increased experience in endoscopy has led to an increased frequency of its proper diagnosis. Various methods are used to achieve successful hemostasis by endoscopy in Dieulafoy lesion; however, comparative studies about the success rates of these methods are still needed. In this study, we compared two of these endoscopic hemostatic methods: band ligation, and injection therapy in Dieulafoy lesions. METHODS: In this prospective study, 18 patients admitted to the Emergency Surgical Unit between January 2002 and December 2005 with upper gastrointestinal bleeding diagnosed as Dieulafoy lesion were included. Diagnose of Dieulafoy lesion was made at initial or second-look endoscopy. Patients were randomized in two groups according to therapy method: injection therapy and band ligation groups. Therapy was applied immediately after recognizing the lesion at the same endoscopic procedure. Two groups were compared regarding demographical data, presence of comorbid diseases, history of medication and previous gastrointestinal system bleeding, hemodynamic status, laboratory values, need for transfusion, endoscopic findings, success rate of the treatment method, mean hospital stay, complications, and recurrence of bleeding. RESULTS: Of 588 patients admitted with upper gastrointestinal hemorrhage, Dieulafoy lesion was recognized in 18 cases (3.1%) at initial or second-look endoscopy. All patients were men with a mean age of 62.8 (range, 30-80) years. Band ligation was applied to ten patients and the remaining eight were treated by injection therapy. During the follow-up period, rebleeding occurred in six of the patients (75%) with injection therapy, whereas no rebleeding occurred for the patients in the band ligation group. The rebleeding rate and mean hospital stay was significantly higher for the injection therapy group. CONCLUSIONS: Our study suggests that of the endoscopic treatment methods, band ligation is superior to injection therapy for the treatment Dieulafoy lesions.

Primary omental hydatid cyst.

Hydatid disease is still a frequently seen disease in endemic area like South America, Middle Asia and South Europe as well as Turkey. Although the disease occurs more frequently in liver and lungs, it can be seen in any part of the body. In this report we present a case of isolated omental hydatid disease which is a rare entity in the English literature.

Effects of nimodipine and pentoxyfylline in prevention of hepatic ischemic damage in rats at normal and hypothermic conditions.

Hepatic ischemia should be considered in serious liver injury, liver tumor resection and liver transplantation. There are other conditions that decrease hepatic blood flow and cause hepatic ischemia, such as hemorrhagic shock, sepsis, hepatic artery ligation, trauma, and certain vascular lesions. In this study, effects of nimodipine (a calcium channel blocker) and pentoxyfylline (a derivative of methylxanthine) on duration and degree of hepatic ischemia in rats at normothermic and hypothermic conditions are investigated. This study was performed on 6 groups of Wistar Albino type rats, each group consisting of 7 rats. Groups were separated into normothermic (A) and hypothermic (B) conditions AI-Control group, AII-Nimodipine group and AIII-Pentoxyfylline group, B IV-Control group, BV-Nimodipine group and BVI-Pentoxyfylline group respectively. After hepatic pedicle occlusion lasting 45 min, blood samples were drawn from the rats for evaluation of alanine aminotransferase (ALT), aspartate transaminase (AST) and lactate dehydrogenase (LDH) values. Moreover, hepatic biopsies were taken to assess pathological changes under electron microscopy. These changes were evaluated through a grading system. As a result; it has been shown that both nimodipine and pentoxyfylline delayed effects of hepatic ischemia in a statistically significant manner in comparison with the control group and these effects were found to be more significant in hypothermic conditions.

Rectus sheath hematoma: three case reports.

INTRODUCTION: Rectus sheath hematoma is an uncommon cause of acute abdominal pain. It is an accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear. It could occur spontaneously or after trauma. They are usually located infraumblically and often misdiagnosed as acute abdomen, inflammatory diseases or tumours of the abdomen. CASE PRESENTATION: We reported three cases of rectus sheath hematoma presenting with a mass in the abdomen and diagnosed by computerized tomography. The patients recovered uneventfully after bed rest, intravenous fluid replacement, blood transfusion and analgesic treatment. CONCLUSION: Rectus sheath hematoma is a rarely seen pathology often misdiagnosed as acute abdomen that may lead to unnecessary laparotomies. Computerized tomography must be chosen for definitive diagnosis since ultrasonography is subject to error due to misinterpretation of the images. Main therapy is conservative management.

Albendazole is not effective for primary treatment of hepatic hydatid cysts.

INTRODUCTION: In current practice, minimal invazive interventions such as percutaneous drainage and laparoscopic surgery in adjunct treatment with benzimidazoles have been gaining acceptance in treatment of hydatid cystic disease with minimal morbidity and mortality. In this prospective study, the efficacy and validity of primary medical therapy in the treatment of hydatid cystic disease has been investigated. PATIENTS AND METHODS: Sixty-five patients with hepatic cystic disease were treated with albendazole alone between January 2004 and June 2007. All of the patients were administrated albendazole as 10 mg kg(-1) day(-1) divided into two equal doses for 6 months with ultrasonography (USG), serological tests, full-blood cell count and hepatic function tests performed in 2 months intervals in the course of treatment. RESULTS: Fifty of the patients were female and 15 were male with a mean age of 47.0+/-16.9 (17-80). A total number of 106 cysts were present in 65 patients. Mean cystic diameter was 5.5+/-3.6 (1-16). In 41 of the patients, cysts were solitary and in remaining 24 patients cysts were multiple. Mean follow-up period was 28.3+/-8.6 (12-42) months. The overall success rate of albendazole therapy was 18% (12/65) in the study. CONCLUSION: Albendazole therapy for hepatic hydatidosis is not effective in the vast majority of patients and, therefore, should not be used as the primary therapy for patients who are surgical candidates.

Short-term effects of gallbladder perforations during laparoscopic cholecystectomy on respiratory mechanics and depth of pain.

BACKGROUND: In this study the effects of gallbladder perforations during laparoscopic cholecystectomy on respiratory mechanics and depth of pain in the postoperative period was evaluated. METHODS: Between April 2004 and February 2006 we planned to perform 179 laparoscopic cholecystectomies. One hundred of these patients were included in this study. Patients were divided into two groups: group 1 with gallbladder perforation during the operation and group 2 without perforation. Two groups were compared regarding age, gender, comorbidities, mean hospital stay, respiratory function tests, and postoperative pain scores. RESULTS: Gallbladder perforation occurred in 33 patients (33%). The male-to-female ratio of group I was 5/28. In group 2 the male-to-female ratio was 12/55. Age and perforation had a significant correlation according to Spearman's correlation test (p < 0.05, r = 0.211). Regarding respiratory function tests and arterial blood gases analysis, there was a significant decrease in both groups postoperatively but perforation had no effect on them. No statistically significant difference occurred regarding mean hospital stay and postoperative visual pain scores (p > 0.05). CONCLUSION: Gallbladder perforation during laparoscopic cholecystectomy had no effect on postoperative respiratory mechanics and depth of pain.

Postoperative recurrence in hepatic hydatid disease.

Recurrence of hepatic hydatid disease is still a serious problem in endemic areas like our country. In this study, we present the causes and management of recurrences after surgical therapy of the hepatic hydatid cysts. Hepatic hydatid cyst patients treated surgically and followed afterward at Istanbul University, Cerrahpasa Medical Faculty, Department of General Surgery between January 1998 and January 2003 were evaluated retrospectively. During this period, 172 primary patients with hepatic hydatid disease were attended to at our clinic. Morbidity and mortality rates for this series were 5.8% and 0.58%, respectively. Recurrence rate was 4.65% during the follow-up period of 60.5 months (range, 25-84 months). Primary causes of recurrence were thought to be unnoticed cysts with exophytic development due to inadequate incision and exposition and spreading of the disease during conservative operative interventions. It is concluded that selection of the proper incision allowing complete exposition, and performance of pericystectomy in solitary, peripherally located cysts prevent recurrence.
