RESUMO

OBJECT VES: This study presents early and long term (5 years) outcome of 61 complicated pilonidal sinus disease cases undergoing V-Y advancement flap method together with the literature data. METHOD: Data of 336 patients undergoing surgery for pilonidal sinus disease between 2008 and 2012 were retrospectively analyzed. Patients with defect size ≥ 10 cm, and more than one subcutaneous sinus tunnels were assumed to have complicated pilonidal sinus disease. A total of 61 patients were included in the study. Age, gender, type of surgery, duration of hospitalization, time of drain removal, pre-operative complications, and relapse rates at post-operative 5th year were analyzed. RESULTS: Of the 66 patients, 51 underwent unilateral V-Y advancement and 10 patients had bilateral V-Y plasty. Mean duration of operations was 66.87±18.37 minutes for total, 61.02±12.30 minutes for unilateral V-Y plasty, and 96.70±15.04 minutes for bilateral V-Y plasty. Hemovac drains were removed at 5.59±1.91 days averagely, 5.16±1.37 in unilateral group, and 7.80±2.74 in bilateral V-Y plasty group. Of the 4 patients who developed wound site infection, 2 had unilateral and 2 had bilateral V-Y flap advancement. Postoperative hematomas developed in 2 patients with unilateral flap and one patient with bilateral flapss. Seroma occurred in 2 patients with unilateral flap and one patient with bilateral flaps. Dehiscence developed two patients, one patient from each group. The mean duration of hosptalization was 5.98±2.21 days; 5.49±1.52 in unilateral group, and 8.50±3.34 in bilateral group. Early or late relapse was not seen in any groups. CONCLUS ON: V-Y advancement flap technique can be applied as an efficient method in the treatment of complicated pilonidal sinus disease due to low relapse and complication rates. KEY WORDS: Advancement flap, Complicated pilonidal sinus, Pilonidal sinus, V-Y flap.

RESUMO

BACKGROUND This study aimed to assess treatment outcomes of the cleft lift procedure and V-Y flap technique in the treatment of recurrent pilonidal sinus disease (PSD). MATERIAL AND METHODS A total of 51 patients who underwent cleft lift procedure and 43 patients who underwent fasciocutaneous V-Y flap technique were evaluated. The demographic characteristics, previous operations, duration of symptoms, perioperative complications, duration of operation and hospital stay, duration of draining of all patients, and recurrence of PSD were recorded. RESULTS The mean operation time was 35.61±5.254 min in the cleft lift group (CLG) and 57.42±7.327 min in the V-Y flap group (VYFG) (p=0.001). No wound dehiscence was found in the VYFG and 5 patients (9.8%) had wound dehiscence in the CLG (p=0.035). Draining time was 1.39±0.603 days in the CLG and 2.79±0.638 days in VYFG (p=0.001). The mean hospital stay was 1.75±0.523 days in the CLG and 3.77±1.02 days in the VYFG (p=0.001). Two patients (3.9%) in the CLG had recurrence and no recurrence was reported in the VYFG (p=0.189) in the given time interval. CONCLUSIONS Both methods in treatment of recurrent PSD can be preferred because of low complication and recurrence rates. Because no recurrence was found after the V-Y flap technique, it appears to be a preferable method despite some disadvantages.

RESUMO

OBJECTIVES: The aim of this study was to investigate the role of several cytokines including IL-2, IL-6, IL-8, IL-10, and TNF-α in the diagnosis of HPB cancers. MATERIALS AND METHODS: The prospective study was performed between October 2007 and September 2014. The study included 226 patients who were divided into 5 groups depending on their postoperative and histopathologic diagnosis: Control group included 30 healthy volunteers. Hepatocellular cancer (HCC) group included 24 patients diagnosed with HCC. Gallbladder cancer (GBC) group included 36 patients diagnosed with GBC. Cholangiocellular carcinoma group included 64 patients diagnosed with cholangiocellular carcinoma. Pancreatic cancer group included 72 patients diagnosed with pancreatic cancer. Serum levels of IL-2, IL-6, IL-8, IL-10, and TNF-α were measured using an enzyme-linked immunosorbent assay kit in accordance with the guidelines of the producer. RESULTS: Serum TNF-α concentration was significantly higher in the cholangiocellular carcinoma and pancreatic cancer groups compared to other groups. IL-6 and IL-10 were significantly increased in both the HCC and GBC groups, IL-2, IL-6, IL-10, and TNF-α in the cholangiocellular carcinoma group, and IL-2, IL-6, IL-8, and TNF-α in the pancreatic cancer group. CONCLUSION: We suggest that cytokines can be used as useful markers in the diagnosis of HPB cancers.

RESUMO

Bochdalek hernia (BH) is the most common type of congenital diaphragm hernia and is rarely seen in adults. In adult patients, BH often remains asymptomatic or presents with nondiagnostic symptoms and may lead to complications, though rarely. The necrosis and perforations occurring in the hernia may lead to mortality. In this report, we present a 34-year-old pregnant woman at 24 gestational weeks who presented with Bochdalek hernia causing gastric volvulus associated with perforation and intra-abdominal hemorrhage associated with splenic rupture.

RESUMO

Foreign body ingestion can be caused by many factors, including hallucination in patients with mental retardation. Most ingested foreign bodies are naturally discharged, though surgical intervention is necessary in some cases. Endoscopic intervention often leads to successful outcome, though open surgery may be required in certain instances. A 29-year-old mentally retarded woman presented to emergency services with a 2-day history of right lumbar pain that increased with movement. Physical examination revealed no specific sign beyond palpable tenderness in the right lumbar region. Radiological examination revealed a metal nail in the upper right quadrant, stretching obliquely toward the retroperitoneum. Endoscopy failed, and the nail was extracted via laparotomy. Foreign body ingestion may occur in patients of any age, but is more common in the pediatric population and in patients with mental retardation. Commonly ingested foreign bodies include daily objects, toys, and dentures, though they may differ in patients with mental retardation. The treatment of such cases requires a diversity of methods and experience. Foreign body ingestion should be kept in mind when a patient presents with pain in the right lumbar region, particularly in patients with mental retardation.

RESUMO

BACKGROUND Planned re-laparotomies are a series of surgical interventions that are rarely used and have a high mortality rate. The aim of this study was to investigate the factors affecting mortality and the effectiveness of the use of the Bogota bag for temporary closure of the abdomen in patients for whom re-laparotomy was planned. MATERIAL AND METHODS A retrospective examination was made of data of patients in whom a Bogota bag was used in planned re-laparotomies for various reasons in the General Surgery Department of Suleyman Demirel University Medical Faculty between June 2008 and April 2014. RESULTS Bogota bags were used in a total of 38 patients, comprising 23 (60.5%) males and 15 (39.5%) females, with a mean age of 58.94±17.89 years. The mean period of hospitalization was 14.5 days (range, 1-143 days) and the mean number of operations during that time was 3 (range, 1-11). The mean duration of intensive care unit stay was 6 days (range, 1-143 days). Malignancy was determined in 8 patients (21.1%). Indications were intra-abdominal sepsis in 23 patients (60.5%), mesenteric vascular disease in 10 patients (26.3%), and packing was required in 5 patients (13.2%). Mortality developed in 25 patients (65.8%). A significant relationship was determined between mortality and a diagnosis of mesenteric artery ischemia (p: 0.035). The mortality rate was 56% (n: 13) in patients diagnosed with intra-abdominal sepsis. A relationship was determined between mortality and age (p: 0.015), duration of hospital stay (p: 0.007), need for cardiac inotrope (p: 0.01), and need for mechanical ventilation (p: 0.01). The mean Apache II score was 26.4±5 for patients who died and 15.8±5.2 for surviving patients (p<0.001). In 5 (38.4%) of the 13 surviving patients, primary repair was applied to the abdomen, and in the remaining 8 patients abdominal wall repair was performed using dual mesh. CONCLUSIONS In patients in whom a Bogota bag was used, which is a cheap and easy method for temporary closure of the abdomen, the high mortality rates seen are related to diagnosis, Apache II score, age, and organ failure.

RESUMO

Introduction. Acute appendicitis is the most common cause of acute abdomen, but atypical appendicitis may lead to delayed diagnosis and related complications. In this report, we present a very rare case of acute appendicitis causing right hydronephrosis. Case Report. A 54-year-old male patient who had been receiving antibiotic therapy due to the diagnosis of urinary tract infection for the last one week but had no clinical improvement was admitted to the emergency service. Abdominal computed tomography (CT) showed right hydronephrosis and a pelvic abscess. After appendectomy and abscess drainage had been performed, hydronephrosis was completely recovered. Discussion. The use of appendicitis scoring systems, abdominal ultrasonography (USG), abdominal CT, and diagnostic laparoscopy can be useful for the diagnostic process in patients presenting with acute abdomen. In our patient, we considered that the surgical treatment was delayed since the symptoms of acute appendicitis were suppressed by the antibiotic therapy that was being administered due to the complaints including symptoms of urinary tract infections. Conclusion. Atypical appendicitis may cause a delay in the diagnosis of acute appendicitis and thus may lead to serious complications such as right hydronephrosis, prolonged hospital stay, increased morbidity and mortality, and increased antibiotic resistance.

RESUMO

Introduction. Unintentional foreign body ingestion commonly occurs accidentally in children aged between 3 months and 6 years and at advanced ages or results from psychiatric disorders such as hallucination in patients with mental retardation. Most of the ingested foreign bodies are naturally discharged from the body but some of them may require surgical intervention. Presentation of Case. A 29-year-old mentally retarded female patient was admitted to the emergency service with a two-day history of abdominal pain, nausea, and vomiting. Physical examination revealed abdominal tenderness, defense, and rebound on palpation. Radiological examination revealed diffuse air-fluid levels and a radiopaque impression of a metal object in the right upper quadrant. The metal teaspoon causing ileal perforation was extracted by emergency laparotomy. On postoperative day 7, the patient was uneventfully discharged following a psychiatric consultation. Discussion. Foreign body ingestion can occur intentionally in children at developing ages and old-age patients, or adults and prisoners, whereas it may occur unintentionally in patients with mental retardation due to hallucination. However, repeated foreign body ingestion is very rare in individuals other than mentally retarded patients. Conclusion. Mentally retarded patients should be kept under close surveillance by surgeons and psychiatrists due to their tendency to ingest foreign bodies.

RESUMO

BACKGROUND: Meckel's diverticulum (MD), the most common congenital anomaly of the gastrointestinal tract, is a true diverticulum. MD is mostly seen in pediatric age groups but may be seen in adults as well. Is twice common in men than women. Surgical treatment is required in symptomatic MD patients. We present a 21-year-old female patient who was admitted with acute abdomen and underwent diverticulectomy with diagnosis of Meckel's diverticulum. PRESENTATION OF CASE: The 21-year-old female patient was admitted to emergency service with abdominal pain, nausea and vomiting. Physical examination revealed abdominal distention, rebound tenderness and defense. Abdominal radiography revealed air-fluid levels. White blood cell count was high. In the exploration, torsion of MD was observed and diverticulectomy was performed. Histopathologic analysis indicated the presence of MD. The patient recovered without complication, and was uneventfully discharged. DISCUSSION: MD is found in 2% of the general population. Common complications of MD include gastrointestinal bleeding, intestinal obstruction, perforation and diverticulitis. However, axial torsion of MD is a rare complication. Simple diverticulectomy is sufficient in the treatment of most MD cases; however, ileal resection may be required in some cases. Diagnosis of MD is established by histopathologic analysis. CONCLUSION: Although MD is known as a pediatric disease, it is likely to occur in adults as well. Axial torsion of Meckel's diverticulum should be kept in mind the adults presenting with symptoms of acute abdomen.

RESUMO

BACKGROUND: Solid organ injury after abdominal trauma is a common condition, however, injury of the local recurrent tumoral masses following abdominal trauma is rare. The injuries and bleeding in recurrent tumors tend to be highly serious since they are more fragile. The bleedings caused by renal cell carcinomas and by the traumatic laceration of their recurrence commonly occur in the retroperitoneum. In this report, we present a 55-year-old female patient who underwent emergency surgery due to intraabdominal bleeding and bleeding was from the recurrence of a renal cell carcinomas. PRESENTATION OF CASE: The 55-year-old female patient was admitted to the emergency service with intraabdominal bleeding. Physical examination revealed tenderness in the right lower quadrant, particularly in the traumatic area. Ultrasonography and computed tomography revealed diffuse intraabdominal fluid and a ruptured bleeding mass was excised. Pathological analysis indicated that the mass was isolated local recurrence of renal cell carcinoma. DISCUSSION: Solid organ injury caused by blunt abdominal trauma may be accompanied by tumoral laceration; however, minor bleeding may occur in cases with blunt trauma, coexistence of blunt abdominal trauma with local recurrence and massive bleeding is extremely rare. Control of bleeding is more challenging in tumoral tissues compared to normal tissues. The bleeding intraabdominal area rather than the retroperitoneal area, and this condition was attributed to the peritoneal tear caused by the trauma. CONCLUSION: Local recurrent tumoral masses may be the source of the intraabdominal massive bleeding after blunt trauma.

RESUMO

Brucellosis, a zoonosis that is common worldwide, is endemic in many countries, primarily those of the Mediterranean region (including Turkey). Human brucellosis is a systemic infection with a wide clinical spectrum. Although hepatic involvement is very common during the course of chronic brucellosis, hepatic abscess is a very rare complication of Brucella spp. infection. We present a case of hepatic abscess caused by Brucella melitensis, which resembled the clinical presentation of surgical acute abdomen.

RESUMO

Introduction. The incidence of gallbladder cancer presenting with acute cholecystitis is 2.3%, squamous cell carcinoma is rarely seen, and overlap of acute cholecystitis and squamous cell carcinoma is a very rare condition in the literature. Presentation of Case. A 75-year-old woman was admitted to emergency service with a pain in the right upper quadrant, nausea, and vomiting. The patient was considered as having acute cholecystitis. During the exploration because Hartman's pouch was not dissected, it was adhered to the cystic duct and had fibrotic adhesion. It could not be understood whether this adhesion was a tumor or a fibrotic tumor and thus we performed cholecystectomy with a 1 cm resection of the choledochus. Pathological examination revealed the presence of (R0), T1 N0 M0 squamous cell carcinoma with clean resection borders and there was no in tumor five dissected lymph nodes. The patient has been followed up for about two years and no clinical problem has been observed throughout the follow-up. Discussion. Acute cholecystitis with gallstones may overlap with gallbladder cancer and generally presents nonspecific symptoms. No additional imaging techniques were performed since no clinical sign except for the wall thickening was detected and no suspected malignancy such as mass was detected on USG. Squamous cell carcinoma of the gallbladder shows poor diagnosis, but since its overlap with cholecystitis presents early symptoms and thus leads to early diagnosis and effective treatment, the localization of the carcinoma is of prime importance. Conclusion. Gallbladder cancer should be kept in mind in elderly patients with acute cholecystitis.

RESUMO

OBJECTIVES: To investigate the protective effects of L-carnitine (LC) on lungs in an experimental obstructive jaundice (OJ) model. METHODS: This was conducted for 2 months between May 2011 and July 2011 at Suleyman Demirel University School of Medicine Experimental and Clinical Research Center, Isparta, Turkey. Thirty-eight Wistar-Albino rats with an average weight of 250-300 g were divided into 3 groups of control, OJ, and OJ + L-carnitine treatment (LCT). L-carnitine was injected intravenously into the tail vein at a dose of 50 mg/kg/day for 10 days to the LCT group. Animals were sacrificed 10 days later. Enzyme levels were measured in the lung tissue; malondialdehyde, myeloperoxidase (MPO), glutathione peroxidase (GSH-Px), catalase, and superoxide dismutase. Tumor necrosis factor-alfa, interleukin 6 (IL-6), IL-8, and C-reactive protein levels were studied in plasma samples. Histopathological changes in the lungs were examined.  RESULTS: There was a decreased in GSH-Px, MPO, and IL-8 levels (p less than 0.05) in the LCT group. The histopathological examination showed that neutrophil leukocyte infiltration and edema formation decreased and destruction of lung parenchyma disappeared following the treatment with LC (p less than 0.05).  CONCLUSION: L-carnitine has a protective effect against lung damage due to experimental obstructive jaundice, possibly by altering anticytokine and antioxidant activity, and by decreasing the neutrophil migration.

RESUMO

Limy bile is a relatively rare condition, in which a radiopaque material is visible in the gallbladder on plain radiography or computerized tomography. Cases of complicated hyperparathyroidism are extremely rare. We report a patient with right upper quadrant and epigastric pain and extremity weakness in whom abdominal tomography showed limy bile in the gallbladder and laboratory values showed high levels of serum calcium and parathormone.

RESUMO

The endoscopic placement of biliary stents for benign and malignant biliary disease has been performed for over a decade. Several complications of stent placement have been described such as pancreatitis, hemorrhage, cholangitis, and perforation. Migration of biliary stents is a rare event, which can cause severe complications such as gastrointestinal tract perforation. We report the case of a 26-year-old woman with a cecum perforation due to biliary stent migration. We present the second case of cecal perforation related to the migration of a biliary stent.

RESUMO

BACKGROUND: Many experimental studies have verified that obstructive jaundice (OJ) causes bacterial translocation (BT). OBJECTIVES: The aim of this study was to assess to whether C-Reactive Protein (CRP) can be used to detect bacterial translocation induced by biliary obstruction. MATERIAL AND METHODS: Twenty rats were divided into two groups containing 10 rats each: sham-operated controls and the obstructive jaundice (OJ) group. All procedures were performed aseptically. After an upper midline incision, the common bile duct (CBD) was identified, mobilized, ligated and divided. The sham-operated animals had a similar incision, followed by mobilization of the CBD, without ligation or division. Ten days after the first operation, a second laparotomy was performed. Blood samples were collected for culture and serum CRP analysis. In addition, liver, spleen, and mesenteric lymph node (MLN) specimens were taken for microbiological culture to determine the presence of BT. BT was considered positive if there was any bacterial growth in the MLN, liver, spleen, or blood cultures; a lack of bacterial growth indicated a negative BT. RESULTS: The OJ group had significantly higher rates of bacterial translocation than the sham-operated group (p = 0.002). Mean CRP levels (ng/mL) were 8.7 ± 11.8 and 18.6 ± 17.2 in the sham-operated group and the OJ group respectively. There was no significant difference in mean CRP levels between the two groups (p = 0.257). Mean CRP levels were 4.5 ± 4.3 and 24.9 ± 16.4 in the BT (-) and BT (+) groups respectively (p = 0.003). A marked increase in CRP levels paralleled an increase in BT. CONCLUSIONS: This study has demonstrated a direct relationship between BT and CRP levels in an experimental OJ model.

RESUMO

BACKGROUND: In previous studies, changes in the surface of the peritoneum during laparoscopic surgery are well defined. Nevertheless, almost all of these studies were performed on rodents via scanning electron microscopy. In the present study, structural alterations of the mesothelial cells of peritoneum were examined during laparoscopic cholecystectomy using transmission electron microscopy. METHODS: Twenty patients with symptomatic cholelithiasis were included in the study. Peritoneal biopsy was performed immediately after CO2 pneumoperitoneum creation and at the end of surgery just before gallbladder removal. Biopsies were taken from the right upper quadrant, i.e., apart from operative manipulation. Peritoneal sample cross-sections were compared using transmission electron microscopy. RESULTS: The carbon dioxide pneumoperitoneum during laparoscopic cholecystectomy caused deteriorations of the peritoneal mesothelium. Apoptosis were developed in mesothelial cells. Bulging of mesothelial cells, irregular cell junctions, focal intercellular clefts, apical cell membrane degeneration, deep nuclear invaginations, and lipid droplets in the cytoplasm of the mesothelial cells were other remarkable findings. Mesothelial edema also was determined. DISCUSSION: As seen in previous studies, basement membrane nudity appeared after carbon dioxide pneumoperitoneum could be attributable to mesothelial cell apoptosis, deterioration of the cell structure, and cell organelles.

RESUMO

BACKGROUND: Post-ischaemic intestinal tissue damage appears to be due to the formation of oxygen radicals. Free radical-initiated lipid peroxidation following intestinal ischaemia/reperfusion (I/R) may disrupt mucosal integrity. Indirectly, the radicals trigger the accumulation of neutrophils within the affected tissue, initiating inflammatory processes that lead to severe mucosal lesions. We have investigated the protective effect of bencyclane fumarate, a vasodilating Ca(2+) channel blocker, which has been used for the treatment of peripheral arterial occlusive diseases, on intestinal ischaemia reperfusion (IR) injury in rats. METHODS: Forty-eight Wistar albino rats were divided into three groups: a sham-operated group (no IR injury, n = 16), an ischaemic control group (IR, n = 16), and BF-treated group (pretreatment 5 mg/kg bencyclane fumarate + IR, n = 16). A marker for lipid peroxidation, namely malondialdehyde; free radical scavengers, glutathione peroxidase, catalase and superoxide dismutase levels; an index of polymorphonuclear neutrophils, myeloperoxidase activity and mucosal damage were investigated. RESULTS: Malondialdehyde levels, myeloperoxidase activity and the severity of mucosal damage were decreased in the BF group. In addition, in the BF group, glutathione peroxidase, catalase and superoxide dismutase levels were higher compared with the IR group. CONCLUSION: The pretreatment of rats with bencyclane fumarate before intestinal ischaemia attenuates the mucosal damage in intestinal IR injury, probably by altering lipid peroxidation, neutrophil accumulation and antioxidant activity.
