BackgroundEntrapped anorectal foreign bodies are being encountered more frequently in clinical practice. Although entrapped foreign bodies are most often related to sexual behavior, they can also result from ingestion or sexual assault.MethodsBetween 1999 and 2009, 15 patients with foreign bodies in the rectum were diagnosed and treated, at Izmir Training and Research Hospital, in Izmir. Information regarding the foreign body, clinical presentation, treatment strategies, and outcomes were documented. We retrospectively reviewed the medical records of these unusual patients.ResultsAll patients were males, and their mean age was 48 years (range, 33–68 years). The objects in the rectum of these 15 patients were an impulse body spray can (4 patients), a bottle (4 patients), a dildo (2 patient), an eggplant (1 patient), a brush (1 patient), a tea glass (1 patient), a ball point pen (1 patient) and a wishbone (1 patient, after oral ingestion). Twelve objects were removed transanally by anal dilatation under general anesthesia. Three patients required laparotomy. Routine rectosigmoidoscopic examination was performed after removal. One patient had perforation of the rectosigmoid and 4 had lacerations of the mucosa. None of the patients died.ConclusionsForeign bodies in the rectum should be managed in a well-organized manner. The diagnosis is confirmed by plain abdominal radiographs and rectal examination. Manual extraction without anaesthesia is only possible for very low-lying objects. Patients with high- lying foreign bodies generally require general anaesthesia to achieve complete relaxation of the anal sphincters to facilitate extraction. Open surgery should be reserved only for patients with perforation, peritonitis, or impaction of the foreign body.

OBJECTIVE To investigate the relation between fruit seeds, plants residuals and appendicitis. METHODS Among cases that underwent appendectomy, the appendicitis cases having fruit seeds and undigested plant residuals in their etiology were examined retrospectively. Also, histopathological features, age, sex, and parameters of morbidity and mortality were used. RESULTS Fruit seed was found in one case (0.05%) with presence of pus in appendix lumen, undigested plant residuals in 7 cases (0.35%). It was determined that there were appendix inflammation in 2 of the plant residuals cases, while there were obstruction and lymphoid hyperplasia in the appendix lumen of 5 cases. No mortality was observed. CONCLUSIONS The ratio of acute appendicitis caused by plants is minimal among all appendectomised patients, but avoidence of eating undigested fruit seeds and chewing plants well may help to prevent appendicitis.

Gossypiboma (retained surgical sponge) is a pseudotumor within the body that is composed of non-absorbable surgical material with a cotton matrix. Because the symptoms of gossypiboma usually are nonspecific and may appear years after surgery, the diagnosis of gossypiboma may be difficult because the condition may mimic a benign or malignant soft-tissue tumour in the abdomen and pelvis. A 61-year-old woman with a one-year history of left upper-quadrant pain and weight loss was referred to our center. She had undergone peptic ulcer perforation 23 year ago. Physical examination revealed dullness and palpable mass in the left upper abdomen. On examination by computed tomography (CT), a hypodense mass of 12 cm in diameter between the greater curvature of the stomach, pancreas, and splenic hilus was detected. Upon exploration, a mass lesion of 10 cm in diameter was detected between the greater curvature of the stomach and splenic hilus, which caused dense adhesions not in communication with the pancreas. It was excised and a splenectomy was performed. After a macroscopic examination, the mass lesion was diagnosed as gossypiboma. Although ultrasonography (US), CT, angiography, and magnetic resonance imaging (MRI) may be used to diagnose gossypiboma, definitive diagnosis is possibile only upon surgery or histopathological examination. As a result, when an abdominal mass is observed, surgeons should carefully investigate the patient’s past surgical history while taking the possibility of gossypiboma into consideration.

Introduction Hypertriglyceridaemia (HT)-induced pancreatitis rarely occurs unless triglyceride levels exceed 1000 mg/dl. Hypertriglyceridaemia over 1,000 mg/dl can provoke acute pancreatitis (AP) and its persistence can worsen the clinical outcome. In contrast, a rapid decrease in triglyceride level is beneficial. Insulin-stimulated lipoprotein lipase is known to decrease serum triglyceride levels. However, their efficacy in HT-induced AP is not well documented. Aim To present 12 cases of AP successfully treated by insulin administration. Material and methods Three hundred and forty-three cases of AP were diagnosed at our clinic between 2005 and 2012. Twelve (3.5%) of these cases were HT-induced AP. Twelve patients who suffered HT-induced AP are reported. Initial blood triglyceride levels were above 1000 mg/dl. Besides the usual treatment of AP, insulin was administered intravenously in continuous infusion. The patients’ medical records were retrospectively evaluated in this study. Results Serum triglyceride levels decreased to < 500 mg/dl within 2–3 days. No complications of treatment were seen and good clinical outcome was observed. Conclusions Our results are compatible with the literature. Insulin may be used safely and effectively in HT-induced AP therapy. Administration of insulin is efficient when used to reduce triglyceride levels in patients with HT-induced AP.

OBJECTIVE Fourniers gangrene is a progressive, necrotizing fasciitis due to synergistic infection of the perineum and external genitalia that is associated with high mortality and morbidity. The purpose of this study is to review the diagnostic and treatment methods that effect mortality in Fourniers gangrene. MATERIAL AND METHODS Sixteen patients who were diagnosed and treated at our clinic between 2011 and 2013 due to Fourniers gangrene were retrospectively analyzed. The surviving and non-surviving patient groups were compared in terms of age, sex, onset time of symptoms, isolated microorganisms, concomitant diseases, Fourniers gangrene severity index (FGSI), and length of hospital stay. RESULTS Ten of our cases (62.5%) were male and six (37.5%) were female, with a mean age of 61.2±12.3 (42-73) years. The mortality rate was 18.8% (3 cases). The mean duration of symptoms before admission was 4.31±1.81 (2-8) days. This period was 6.67±1.52 days in patients who succumbed to death, and 3.77±1.42 days in patients who survived (p=0.007). Ten cases (62.5%) had concomitant diabetes mellitus. The most common organism isolated in wound cultures was Escherichia coli (68.7%), and Acinetobacter baumannii, Proteus mirabilis, methicillin-resistant Staphylococcus aureus and Enterococcus spp. in the remaining patients. The mean FGSI of surviving patients was 3.84±1.77, and 7.66±0.57 in fatal cases (p=0.003). The mean length of hospital stay was 25.5 days (2-57) and duration of hospitalization was significantly longer in survivors (p<0.05). CONCLUSION The delay in diagnosis and higher FGSI may be responsible for worsening of prognosis and mortality in Fourniers gangrene. Early diagnosis and determination of the severity of the disease, aggressive surgical debridement and appropriate antimicrobial therapy may improve prognosis.

Introduction Although all studies have reported that laparoscopic cholecystectomy (LC) is a safe and effective treatment for acute cholecystitis, the optimal timing for the procedure is still the subject of some debate. Aim This retrospective analysis of a prospective database was aimed at comparing early with delayed LC for acute cholecystitis. Material and methods The LC was performed in 165 patients, of whom 83 were operated within 72 h of admission (group 1) and 82 patients after 72 h (group 2) with acute cholecystitis between January 2012 and August 2013. All data were collected prospectively and both groups compared in terms of age, sex, fever, white blood count count, ultrasound findings, operation time, conversion to open surgery, complications and mean hospital stay. Results The study included 165 patients, 53 men and 112 women, who had median age 54 (20–85) years. The overall conversion rate was 27.9%. There was no significant difference in conversion rates (21% vs. 34%) between groups (p = 0.08). The operation time (116 min vs. 102 min, p = 0.02) was significantly increased in group 1. The complication rates (9% vs. 18%, p = 0.03) and total hospital stay (3.8 days vs. 7.9 days, p = 0.001) were significantly reduced in group 1. Conclusions Early LC within 72 h of admission reduces complications and hospital stay and is the preferred approach for acute cholecystitis.

Urinary bladder rupture is usually found due to blunt or penetrating traumas and iatrogenic injuries, and spontaneous intraperitoneal perforation is very rare. 57 years old male patient was consulted to general surgery department due to abdominal pain, nausia-vomiting and fever. He had Diabetes Mellitus, Multiple Sclerosis, Leriche Syndrome and operation for benign prostatic hypertrophy 5 years ago on his medical history which the case catheterised him urinary bladder himself frequently in nonsterile conditions. He did not care about sterility. On physical examination, suprapubic defence and rebound was noted more prominently on right lower quadrant. He was taken to operating room with the diagnosis of acute abdomen. On exploration, infection was seen on all layers of the whole urinary bladder, abscess formation and necrosis causing a microperforation which is detected by methylene blue was also present. Intraabdominal abscess drainage, cystostomy and primary suturing of the urinary bladder was performed. Patient died due to sepsis at the 9.th post operative day.

Gastric duplication cysts (GDCs) are uncommon developmental anomalies found primarily in children, being rarely seen in adults. Duplications can occur anywhere in the intestinal tract from the mouth to the anus. Accurate diagnosis of cysts before resection is difficult even using the most advanced imaging techniques. In this report, we present and discuss a case of GDC in a 25-year-old man treated laparoscopically. Patient admitted to our department with complaints of epigastric pain and swelling. Magnetic resonance imaging performed for accurate characterisation showed a 4 cm × 4.5 cm cystic lesion, with heterogeneous signal intensity on T2-weighted images, located in the posterior wall of the stomach. Pre-operative differential diagnosis including gastrointestinal stromal tumour (GIST) was made according to radiological findings. Patient underwent surgery and cyst resected laparoscopically. Histopathological examination suggesting duplication cyst. GDC can easily be mistaken for a GIST, and the clinician as well as radiologist must maintain a high degree of suspicion.

Anaplastic carcinoma of the pancreas (ACP) is a very rare histologic subtype of pancreatic cancer and associated with more aggressive and poor prognosis than pancreatic ductal adenocarcinoma. We aimed to review this rare entity and discuss its clinical features, diagnosis and therapy. We presented a case of a 63-year-old male patient that diagnosed as ACP with cyst formation at a tertiary medical center with a detailed review of the current medical literature. We performed pancreaticoduodenectomy operation with lymph node dissection after diagnosis. Any complication after surgery was not observed. Anaplastic pancreas carcinomas are associated with poor survival when compared to invasive ductal adenocarcinomas. Clinical, radiological, laboratory and histological features may be helpful in making differential diagnosis and should be kept in mind in the diagnosis of this rare pancreatic malignancy.

OBJECTIVE Pilonidal sinus disease (PSD) effects mainly young mens social and work life with frequent recurrence rate. Reoperation for unimproved or recurrent disease is somehow troublesome. Surgeons may think that changing treatment strategy after recurrence may prevent further relapses of PSD. We analyzed patients with recurrent pilonidal sinus to determine their predisposing features for recurrence and the outcomes of the preferred surgical methods. MATERIAL AND METHODS From 2007 to 2012, out of 95 recurrent pilonidal sinus disease (rPSD) patients, 62 operated cases were included and examined retrospectively. Their retrospective data were examined for demographics, 1(st) and 2(nd) operation types, patient satisfaction and pain scores. For cases with insufficient preoperative or postoperative data, phone call and interviews were done to obtain data. Some were kindly invited to the outpatient examination. Students t test, Mann-Whitney U test, and Kaplan Meier test for disease free survival time were used where appropriate. P values less than 0.05 were accepted to be statistically significant. RESULTS Total of 62 rPSD patients were examined. Male:female ratio was 2.9:1. The mean age after 1(st) and 2(nd) operations were 24.7 and 28.1 years, respectively. One and five-year recurrence rates were 33.9% and 66.1%, respectively. The mean interval between the 1(st) and 2(nd) operations was 45.6 months. Excision and midline closure was the most frequent type of operation followed by flap reconstructions and excision-lay open procedures. The 1(st) operation types of rPSD cases were different from that of 2(nd) operations. Pain perception and satisfaction scores were better in flap reconstruction groups. CONCLUSION Reoperative surgery of rPSD is satisfactory with certain precautions. Relapses after flap reconstruction procedures with a well-being period should be referred as second primary disease. Changing surgical strategy is not always indicated as some patients with recurrence have relapsing or second primary disease that have distinct clinical course. Re-flap surgery after any kind of relapse is well appreciated.
