    Post-electric burn ileal perforation is a rare but severe complication leading to high morbidity and mortality if there is delay in diagnosis and management. We are describing a case of electric current injury of left forearm, chest, and abdominal wall with perforation of ileum in an 8-year old boy. Patient was successfully managed by primary closure of the ileal perforation.

    Full Text Available Anorectal malformation is a common anomaly in neonates. Although colorectal perforations have been reported as a complication, ileal perforation is rarely encountered. This is a report of a 2-day-old boy presenting with a low anorectal malformation, complicated with ileal perforation, necessitating laparotomy and ileal repair. Anoplasty was done for the low anomaly. Early presentation and prompt treatment of anorectal malformations is important to prevent such potential life threatening complication.

    A 9-month old 3.2 kg of body weight, male Chihuahua was presented with a history of the intermittent vomiting for two days. Abdominal radiograph showed a foreign body in abdominal cavity which was suggested to be a micro battery in small intestine. Although the dog was treated symptomatically for two days, physical condition of the patient worsened, therefore exploratory laparotomy was performed. A large adhesive lesion involved the perforated ileum and large intestines, was found. A micro battery was stuck in the ileum resulting in a intestinal perforation. A whole of the small intestine was resected because of the cranial mesenteric artery damage during separating the adhesion. The dog lost body weight gradually and died 158 days after first admission of short bowel syndrome

    Rupture of abdominal wall with formation of ventral hernia is a rare complication following blunt abdominal trauma. Small intestinal rupture within such a hernial sac, resulting from a subsequent blunt trauma is rarer still. Ventral hernias often go untreated in developing countries because of their seemingly innocuous nature, ignorance and financial constraints. Blunt trauma in patients with hernia warrants a thorough clinical examination along with evaluation for intestinal injury, since even trivial trauma can cause potentially serious intra-peritoneal visceral injury. A case of fatal traumatic ileal perforation in pre-existing post-traumatic ventral hernia (from blunt trauma sustained 10 years earlier) is being reported. (author)

    Full Text Available A rare case of ileal perforation, as a fatal initial presentation of total colonic aganglionosis (TCA in infancy is reported. A 10-week-old boy, was brought to the emergency department with symptoms of complicated intestinal obstruction. He looked ill, was lethargic, markedly dehydrated and had a severely distended abdomen. An abdominal X-ray revealed multiple air fluid levels seen in a distended small intestine. During exploratory laparotomy the ileum was massively dilated with distal segment perforation. Ileal perforation repair was performed. A totally collapsed microcolon was identified. Biopsies were taken from the high rectum, sigmoid and hepatic flexure. Appendectomy and ileostomy were performed. All biopsies, as well as the appendix, showed absence of ganglion cells. Despite this procedure the patient progressively deteriorated and later died due to sepsis. Ileal perforation in infants is a rare, but potentially fatal initial presentation of TCA. Early detection is essential to prevent life-threatening complications.

    Full Text Available A bezoar is an intraluminal mass formed by the accumulation of undigested material in the gastrointestinal tract. Trichobezoar is a rare condition seen almost exclusively in young women with trichotillomania and trichotillophagia. When not recognized, the trichobezoar continues to grow, which increases the risk of severe complications such as gastric ulceration and even perforation. Formation of a gallstone within the trichobezoar (tricholithobezoar is an event that has not yet been described. We report the case of a 22-year-old woman admitted to the emergency room with signals and symptoms of an epigastric mass and perforative acute abdomen. Radiological study revealed bilateral pneumoperitoneum. Personal history revealed depressive syndrome, trichotillomania and trichophagia. With a diagnosis of visceral perforation, an urgent exploratory laparotomy was performed. This confirmed the diagnosis of gastric perforation due to a large trichobezoar with the formation of a gastrolith that was removed by anterior gastrotomy. Biochemical study of the gastric stone revealed that it was composed of bile salts. There were no complications. The patient was discharged on the 5th postoperative day and was referred for psychiatric treatment.

  14. The prognostic factors in typhoid ileal perforation: a prospective study of 50 patients.

    Science.gov (United States)

    Adesunkanmi, A R; Ajao, O G

    1997-12-01

    To determine the prognostic factors in typhoid ileal perforation, a prospective study was carried out in 50 patients with typhoid ileal perforation confirmed at operation. Attention was paid to pre-operative and post-operative factors. The sex ratio was 4:1 in favour of male, with an age range of 7-42 years and a mean of 19.5 years. The age and sex had no effect on the prognosis. Late presentation, delay in operation, multiple perforations, and drainage of copious quantities of pus and faecal material from the peritoneal cavity adversely affected the incidence of faecal fistula and the mortality rate. The development of faecal fistula significantly affected the mortality rate. Early presentation, single perforation and moderate amounts of pus/faecal matter draining from the peritoneal cavity enhanced the development of wound infection, wound dehiscence and residual intra-abdominal abscess. Fourteen patients (28%) died, 50% of these within the first 5 post-operative days. Seventy-one per cent of the 14 died within 10 days. Thus, surviving for more than 10 post-operative days tends to give a better chance of recovery. In conclusion, this study has attempted to outline those factors with a strong effect on the progression and outcome of typhoid ileal perforation in Nigerian patients.

    Directory of Open Access Journals (Sweden)

    Ryan M. McAdams, MD

    2017-04-01

    Full Text Available Recovery after surgical repair of an ileal atresia with or without intestinal perforation requires prolonged exposure to parenteral nutrition (PN that may lead to PN-associated liver disease. Early liver failure and cholestasis out of proportion for PN exposure may be a harbinger for gestational alloimmune liver disease (GALD, a potentially life-threatening condition that often requires liver transplant if not treated in a timely manner. This case report presents a premature neonate with ileal atresia and multiple jejunal perforations who developed liver failure and was later determined to have GALD. Recognition of clinical and laboratory findings consistent with GALD is essential to promote early treatment, which can enhance neonatal outcomes and impact future pregnancies.

    Primary mediastinal large B-cell lymphoma (PMBCL) is confined to the mediastinum or contiguous nodal areas in most cases. Extramediastinal and abdominal involvement, especially at diagnosis, is extremely rare. Our case describes the first case of histologically proven ileal involvement of PMBCL at diagnosis that led to ileal perforation. Positron emission tomography CT could increase the sensitivity of staging by detecting unusual sites of disease localisation, and could impact clinical management. 2016 BMJ Publishing Group Ltd.

    Full Text Available Abstract Background Using crude mortality and morbidity rates for comparing outcomes can be misleading. The aim of the present study was to compare the outcome of various surgical modalities without and with risk adjustment using Physiologic and Operative Severity Scoring for the enUmeration of Mortality and morbidity (POSSUM score in cases of ileal perforations. Methods Prospective study on 125 patients of ileal perforations. Resection anastamosis (Group I was done in 38 patients, primary repair (Group II in 42 patients and 45 patients had an ileostomy (Group III. The disease severity was assessed in all patients using POSSUM score. The odds of death without and with risk adjustment using POSSUM mortality score were calculated for all groups Results Seventeen patients (14% patients died and 99 (79% developed postoperative complications. Using crude mortality rates Group I appeared to be the best treatment option with only 2 (5% deaths followed by Group II with 5 (12% deaths where as Group III had the worst outcome with 10 deaths (22%. However, Group III (ileostomy patients had higher mean POSSUM mortality and morbidity score (55.55%, 91.33% than Group I (28%, 75.26% and Group II (27%, 73.59%. Taking Group I as the reference (odds ratio, OR1 odds of death were greatest in Group III (OR 5.14, p = 0.043 followed by Group II (OR 2.43, p = 0.306. With risk adjustment using POSSUM mortality score the odds of death decreased in Group III (OR 1.16 p = 0.875. For the whole group, there was a significant association between the POSSUM score and postoperative complications and deaths. Mean POSSUM mortality and morbidity score of those who died (63.40 vs.33.68, p = 0.001 and developed complications (66.32 vs.84.20, p = 0.001 was significantly higher.

    Full Text Available Introduction Small bowel diverticulitis is a rare clinical disease of the small bowel. The incidence of small bowel diverticulitis varies from 0.3 to 2.3 % in the general population. Complications of this rare clinical entity are often confused with other causes of acute abdomen such as acute appendicitis, perforated peptic ulcer, inflammatory bowel disease or ischemic bowel disease. Case Presentation We describe a 65-year-old male with a history of ileal diverticulosis who presented with acute abdomen and was subsequently found to have perforated ileal diverticulitis with abscess formation. Conclusions The case, differential diagnosis, imaging studies, complications and management of this rare clinical disease are discussed.

    Duodenal diverticulum is common, but its perforation is a rare complication. Duodenal diverticulum perforation requires prompt treatments because of its high mortality rate. However, an accurate diagnosis is difficult to make due to nonspecific symptoms and signs. It can be misdiagnosed as pancreatitis, cholecystitis, or peptic ulcer. Herein, we report a case of perforated duodenal diverticulum caused by bezoar in a 33-year-old woman whom was diagnosed by abdomen computed tomography and ultrasonography.

    Full Text Available Preterm infants are highly susceptible to injuries following necessary and often life-saving medical interventions. Esophageal perforation is a rare, yet serious complication that can be caused by aerodigestive tract suction, endotracheal intubation, or nasogastric tube placement. We present the case of a neonate born at 23 weeks plus three days of gestation with chest radiography showing malposition of the nasogastric feeding tube and massive right-sided effusion of Iopamidol in the pleural cavity due to esophageal perforation. In addition, the article summarizes common signs and symptoms associated with esophageal perforation in infants and discusses diagnostic approaches.

  6. Ileal Neobladder: An Important Cause of Non-Anion Gap Metabolic Acidosis.

    St Clair, Jesse W; Wong, Matthew L

    2017-05-01

    The differential diagnosis for a non-anion gap metabolic acidosis is probably less well known than the differential diagnosis for an anion gap metabolic acidosis. One etiology of a non-anion gap acidosis is the consequence of ileal neobladder urinary diversion for the treatment of bladder cancer. We present a case of a patient with an ileal neobladder with a severe non-anion gap metabolic acidosis caused by a urinary tract infection and ureteroenterostomy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Part of the ileal neobladder surgery includes ureteroenterostomy and predisposes patients to several clinically significant metabolic derangements, including a non-anion gap metabolic acidosis. These patients have an increased chronic acid load, bicarbonate deficit, and hypokalemia, which should be appreciated when resuscitating these patients. Copyright © 2017 Elsevier Inc.

    2004-01-01

    To report two cases of ocular perforation during chalazion removal procedures leading to severe vision loss. Observational case series. Two patients presented with unilateral decreased vision after chalazion removal procedures. Complete ophthalmologic examinations were performed. Examination revealed a cherry red spot and perforation site in the first patient. In the second patient, there was an intraocular gas bubble and ischemic retina. Local anesthetic injections for procedures such as chalazia removal can result in ocular perforation. We postulate that the intraocular injections led to extremely high pressures, compromising the blood supply to the retina and optic nerve. Anesthetic injections for all procedures, even chalazia removal, should be done with great caution. It is imperative to avoid injection if ocular perforation is suspected, as the high pressure may cause the majority of the visual morbidity.

    2017-10-01

    Full Text Available Many etiologies are held accountable for nasal septum perforations. Topical nasal drug usage, previous surgeries, trauma, nose picking, squamous cell carcinoma, some rheumatological disorders such as granulomatosis with polyangiitis (Wegener granulomatosis, some infectious diseases such as syphilis and leprosy are among the causes of the perforations. Occupational heavy metal exposures by inhalation rarely may also cause nasal septum perforation. Here, we present a 29-year-old patient without any known diseases, who is a worker at a metallic coating and nickel-plating factory, referred for investigation of his nasal cartilage septum perforation from an otorhinolaryngology clinic. The patient questioning, physical examination and laboratory assessment about rheumatic and infectious diseases were negative. There was a metallic smell in the breath during the physical examination. The analysis showed serum nickel level at 31 μg/l and urine nickel at 18 μg/l (84.11 μg/g creatinine. Other possible serum and urine heavy metal levels were within normal ranges. Nickel exposure is usually together with other heavy metals (chromium or cadmium, it is rarely alone. Nickel ingested by inhalation usually leads to respiratory problems such as reduced olfactory acuity, ulcers, septum perforation or tumors of the nasal sinuses. This case demonstrates the importance of occupational anamnesis and awareness of diagnosis. Int J Occup Med Environ Health 2017;30(6:963–967

    2008-01-01

    Many marine catfish have serrated bony stings ("spines"), which are used in defense against predators, on the dorsal and pectoral fins. While catfish-induced injuries are generally characterized by the pain associated with envenomation, the stings in some species are sufficiently long and sharp to cause severe penetrating trauma. Most injuries are to the hands of victims, commonly fishermen. We report the death of a fisherman caused by myocardial perforation from a catfish sting. To our knowledge, this is the first such description in the medical literature.

    We report the case of a 34-year-old previously fit and healthy male who presented to the accident & emergency department with non-specific abdominal pain. The patient proceeded to undergo laparotomy at which a large mass was found adjacent to the stomach. The impression at surgery was of a lymphoma or gastric carcinoma though CT had reported the likelihood of a fish bone or foreign body causing duodenal perforation. Histology later confirmed the presence of a fish bone surrounded by reactive tissue.

    1993-12-01

    Full Text Available Environmental modifications caused by low tunnels made of perforated transparent polyethylene were determineted in an area alocated at the Federal University of Santa Maria, RS. The perforation densities were 100, 200, 300 and 400 perforations per square meter, corresponding respectively to 0.78% (T1, 1.57% CT2, 2.35% (T3 and 3.14% (T4 of area perforated. The results indicated that perforation density did not significantly affected solar energy availability. As perforation density increased there was a decrease on the average diurnal air temperature which demonstrated the viability of ventilating low tunnels with perforated plastic. It was also observed that inside the perforated tunnels the averages values for soil, air minimun and diurnal temperatures and air relative humidity were higher than on the external environment.

In our case, emergency surgery was planned and the patient refused the operation and was lost at 48 hours of clinical follow-up. We aimed to discuss the etiology of celiac artery thrombosis, briefly. We believe that necrosis and perforation of the stomach due to celiac artery thrombosis deserves to be shared because it is a rare and difficult case to manage.

    The following is a case report involving a 16 year old female with trichotillomania as an antecedent. This patient presented to the Emergency Room with a chief complaint of early satiety and persistent abdominal pain for the past 3 months. However, recently her abdominal pain has worsened and it is now complicated by nausea and vomiting. The physical exam was notable for epigastric pain on deep palpation. The biochemical analysis and abdominal ultrasound were otherwise unremarkable. An esophagogastroduodenoscopy was subsequently performed where a trichobezoar was discovered. It extended from the gastric fundus to the third portion of the duodenum. A surgical extraction of the trichobezoar was then performed. The trichobezoar was found to be 130 cm in length and 8 cm wide at its most cephalad aspect. It is important to note that they also found five mall perforations throughout the duodenum and jejunum. The patient was discharged with outpatient follow up with psychiatry. In this report we describe the case of a patient with Rapunzel syndrome that was complicated by small bowel perforation and we provide a review of the salient literature concerning this syndrome and its associated complications.

    Acute appendicitis is a common surgical cause of abdominal pain in the pediatric population. History and physical examination are atypical in up to a third of patients. Known potential complications of untreated or delayed management of acute appendicitis include appendiceal perforation, periappendiceal abscess formation, peritonitis, bowel obstruction and rarely septic thrombosis of mesenteric vessels. We report an unusual complication of perforated appendicitis. A tubo-ovarian abscess developed secondary to appendicolith migration into the right fallopian tube in a patient who had undergone interval laparoscopic appendectomy for perforated appendicitis. The retained appendicolith was visualized within the obstructed and dilated fallopian tube on contrast-enhanced CT. We discuss the CT imaging features of this unusual complication of perforated appendicitis. (orig.)

    Full Text Available Gossypiboma, an infrequent surgical complication, is a mass lesion due to a retained surgical sponge surrounded by foreign body reaction. In this case report, we describe gossypiboma in the abdominal cavity which was detected 14 months after the hysterectomy due to acute abdominal pain. Gossypiboma was diagnosed by computed tomography (CT. The CT findings were a rounded mass with a dense central part and an enhancing wall. In explorative laparotomy, small bowel loops were seen to be perforated due to inflammation of long standing gossypiboma. Jejunal resection with end-to-end anastomosis was performed. The patient was discharged whithout complication. This case was presented to point to retained foreign body (RFB complications and we believed that the possibility of a retained foreign body should be considered in the differential diagnosis of who had previous surgery and complained of pain, infection, or palpable mass.

    The patient was a woman in her sixties who had received radiation therapy for cancer of uterine cervix 7 years earlier and had been suffering from diarrhea for these several years. The patient was seen at our emergency clinic because of a 5 hour-history of lower abdominal pain at the beginning of July 2010. An abdominal CT scan showed free air and ascites. A high density structure 1.5 cm in size was identified within the small intestine, but its relation with the perforation was obscure. Emergency operation was done with the most likely diagnosis of intestinal perforation and general peritonitis. When the lower abdomen was opened by midline incision, about 200 ml of cloudy ascites was observed and the ileum became white in color and hard resulting from the radiation therapy. A perforation was identified in the ileum about 15 cm distant from the ileocecal valve, and a 1.5-cm sized thin and hard material was palpated within the intestine at the same portion. Ilececal resection including the perforated portion was performed and functional end-to-end anastomosis was made at a grossly normal area. There was a piece of eggshell 1.5-cm in size in the perforated portion in the resected specimen. From this together with histopathologial findings, perforation of the small intestine caused by a piece of eggshell associated with radiation enteritis was finally diagnosed. Small bowel perforation must be kept in mind as a possible late complication of radiation therapy, however, no cases of small bowel perforation caused by eggshell have been reported so far. This rare case is reported here, with a review of the literature. (author)

  7. Perforated small intestine in a patient with T-cell lymphoma; a rare cause of peritonitis

    2016-04-01

    Full Text Available The nontraumatic perforations of the small intestine are pathological entities with particular aspects in respect to diagnosis and treatment. These peculiarities derive from the nonspecific clinical expression of the peritonitis syndrome, and from the multitude of causes that might be the primary sources of the perforation: foreign bodies, inflammatory diseases, tumors, infectious diseases, etc. Accordingly, in most cases intestinal perforation is discovered only by laparotomy and the definitive diagnosis is available only after histopathologic examination. Small bowel malignancies are rare; among them, lymphomas rank third in frequency, being mostly B-cell non Hodgkin lymphomas. Only 10% of non-Hodgkin lymphomas are with T-cell. We report the case of a 57 years’ old woman with intestinal T-cell lymphoma, whose first clinical symptomatology was related to a complication represented by perforation of the small intestine. Laparotomy performed in emergency identified an ulcerative lesion with perforation in the jejunum, which required segmental enterectomy with anastomosis. The nonspecific clinical manifestations of intestinal lymphomas make from diagnosis a difficult procedure. Due to the fact that surgery does not have a definite place in the treatment of the small intestinal lymphomas (for cases complicated with perforation, and beyond the morbidity associated with the surgery performed in emergency conditions, prognosis of these patients is finally given by the possibility to control the systemic disease through adjuvant therapy.

    Full Text Available Hiroyuki Miyatani1, Yukio Yoshida1, Hirokazu Kiyozaki21Department of Gastroenterology, Jichi Medical University, Saitama Medical Center, Saitama, Japan; 2Department of Surgery, Jichi Medical University, Saitama Medical Center, Saitama, JapanAbstract: Colonic perforation caused by upper gastrointestinal (GI endoscopy is extremely rare. A 69-year-old woman was referred to our hospital because of abdominal fullness. Colonoscopy could be performed only up to the hepatic flexure due to an elongated colon and residual stools. Because her symptoms improved, upper GI endoscopy was performed 11 days later. The patient developed severe abdominal pain two hours after the examination. Abdominal X-ray and computed tomography showed massive free air. Immediate laparotomy was performed for the intestinal perforation. After removal of stool, a perforation site was detected in the cecum with an invasive ascending colon cancer. Therefore, a right hemicolectomy, ileostomy, and transverse colostomy were performed. Although she developed postoperative septicemia, the patient was discharged 38 days after admission. Seven months postoperatively, the patient died of lung, liver, and brain metastases. Even in cases with a lesion that is not completely obstructed, it is important to note that air insufflations during upper GI endoscopy can perforate the intestinal wall in patients with advanced colon cancer.Keywords: colonic perforation, colon cancer, upper gastrointestinal endoscopy, fecal peritonitis

    Full Text Available Ingestion of foreign bodies is not an uncommon occurrence, but most of them will pass through the gastrointestinal tract without consequences. Complication such as perforation is rare. We present a case of small bowel perforation secondary to the accidental ingestion of a chicken bone. The patient presented with abdominal pain, constipation and vomiting. Clinical examination confirmed generalized abdominal tenderness and rebound tenderness. Abdominal radiography showed multiple dilated loops of small bowel, and abdominal ultrasound (US showed inflammatory changes on small bowel loops, with free fluid and fluid collection around intestinal loops. The patient underwent an emergency laparotomy. Intra operative findings revealed diffuse fibro purulent peritonitis with abscess between central small bowels loops. At about 60 cm from Bauchini valve we found a perforation of ileum at the anti-mesenteric site caused by a sharp chicken wishbone. The patient was treated with resection of the ileum segment (10 cm and primary end-to-end anastomosis. Even that intestinal perforation by a foreign body is rare, physicians should consider possibility of intestinal perforation by a foreign body in the differential diagnosis of acute abdomen in patients presenting with abdominal pain.

    2010-06-01

    Aortic perforation caused by the friction of a chest tube is a rare but life-threatening complication of coronary artery bypass grafting (CABG). We report a case involving CABG for triple-vessel disease and unstable angina. Reexploration was necessary 24 hours after the operation because of the sudden onset of pronounced bleeding. Perforation of the ascending aorta caused by friction of the chest tube was found. Bleeding was controlled by means of a purse string suture with 4-0 Prolene. Use of pericardium membrane between the heart and the chest tube and the choice of smaller and more flexible Silastic chest tubes in high-risk patients can probably reduce the incidence of this complication.

    Spontaneous intestinal perforations are localized perforations without the typical clinical, radiological, and histopathological features of necrotizing enterocolitis. Spontaneous intestinal perforation is a recently defined clinical entity. The best-known risk factor is prematurity. It is seen 2-3% in very low birthweight infants and 5 % of extremely low birthweight infants. Herein we report an extremely low birthweight infant with spontaneous intestinal perforation, segmental absence of intestinal muscle and an ileal web as an underlying cause. We aimed to draw attention to the segmental absence of intestinal muscle which is rare but increasingly reported cause of spontaneous intestinal perforation and the importance of histopathologic examination of surgical specimens.

    2013-01-01

    A 57-year-old woman, who had undergone Roux-en-Y gastric bypass surgery 9 years earlier, was admitted to the intensive care unit because of pneumonia. Despite antibiotic therapy, she died 40 days later, apparently because of sepsis and organ failure related to the pneumonia. However, the patient's family requested an autopsy, which revealed that her death was due to perforation of the Roux limb of her gastric bypass, which had resulted in severe peritonitis. The perforation was caused by a nasogastric tube inserted for enteral nutrition. We discuss ways nasogastric tubes might be inserted more safely after gastric bypass, the response of Baylor University Medical Center at Dallas to this complication, and the role of autopsy in improving the quality of hospital care.

  14. Spontaneous biliary tract perforations: an unusual cause of peritonitis in pregnancy. Report of two cases and review of literature

    2006-07-01

    Full Text Available Abstract Spontaneous perforations of the biliary tract are rare in adults and even more so during pregnancy. Perforation of the gall bladder is a potentially fatal complication of cholecystitis. The infrequency of perforation in the setting of calculous disease of the gall bladder is probably due to the thickened wall of the organ that has long been the seat of chronic inflammation. Common bile duct perforations have been reported in adults most commonly in association with choledocholithiasis. The diagnosis of biliary tract perforations is often delayed due to their non specific symptoms, which results in high morbidity. Early diagnosis and aggressive therapy are mandatory to alleviate this condition. Delayed diagnoses and treatment may have more serious consequences for pregnant women than for other patients. Very few cases of biliary tract perforations have been reported in pregnant women. We report two such cases in pregnancy: first of a gall bladder perforation associated with cholelithiasis and the second of a common bile duct perforation in pregnancy in which no apparent cause was found.

    2009-02-01

    Full Text Available Abstract Introduction Meckel's diverticulum represents a true diverticulum of the ileum containing all three layers of the bowel wall and is found on the wall of the distal ileum, usually about 2 feet from the ileocaecal valve. Although Meckel's diverticulum is a common congenital abnormality of the gastrointestinal tract, it is often difficult to diagnose. Patients with perforation of Meckel's diverticulum may present with right iliac fossa pain, which mimics acute appendicitis. Case presentation A 17-year-old man presented with a 3-day history of lower abdominal pain. On examination, the patient had tenderness in his right iliac fossa. A provisional diagnosis of acute appendicitis was made. The patient was taken to theatre for laparoscopy with the option of appendicectomy. The appendix was found to be normal. An inflamed and perforated Meckel's diverticulum was found to be the cause of the abdominal pain. Meckel's diverticulectomy was performed. The patient made an uneventful recovery and was discharged with further follow-up in the outpatient clinic. Conclusion Complications of Meckel's diverticulum can be fatal and early recognition leads to appropriate management. This case report highlights the importance of considering Meckel's diverticulum as a differential diagnosis of acute abdomen in a young patient.

    The patient was a 65-year-old man. He had not defecated for a week in early December 2015, and had noticed abdominal pain and abdominaldistension from 4 days prior. The pain and distension worsened, and the patient was rush transported to our hospital. Via abdominal CT we found free air in the upper abdomen, expansion of the small and large intestines, and notably, significant intestinal tract expansion and a gas reservoir in the ascending colon. We found significant narrowing as well as hypertrophy along the entire circumference of the rectum and suspected gastrointestinal perforation due to rectal cancer ileus. Inflammation findings were abnormally high and we performed emergency surgery. We found a laceration on the ascending colon, which had expanded markedly. We elevated that location and installed a colostomy. Following surgery the patient developed mild SSI and ileus, which were alleviated through conservative treatment. A month after the operation we performed a colonoscopy and found a tumor along the entire circumference of the rectum Rs. It was diagnosed as group V tub1-2 via biopsy. We performed surgery in late January 2016(colostomy closure, laparotomy rectal low anterior resection). We are reporting a rare case where rectal cancer ileus caused perforation in the ascending colon.

    Gastrointestinal stromal tumours are the most common mesenchymal malignancies of the gastrointestinal (GI) tract and gastric leiomyosarcoma represent 1-3% of gastric malignancies. We report a case of a 69-year-old black African man who presented with a rare cause of gastric outlet obstruction and duodenal perforation. A Billroth-II gastrectomy was performed and histology confirmed a gastric leiomyosarcoma. It is important to identify the gastric leiomyosarcoma which is a variant of the more common malignant gastrointestinal stromal tumours as the pathogenesis and management are currently well established. As the facilities for differentiating these are not easily available in resource-limited areas gastrointestinal stromal tumours may remain underdiagnosed and undertreated.

    The incidence of appendicitis presenting during pregnancy is less than 1 in 1500. Most cases of endometriosis of the appendix are discovered as a result of incidental appendectomy. True perforated appendicitis in an endometriotic area has not been reported before. The authors report the case of a 28-year-old woman in her 27th week of pregnancy who underwent an appendicectomy for inflamed, perforated appendix with transmural endometriosis and accompanying decidual reaction.

    The acute abdomen accounts for up to 40% of all emergency surgical hospital admissions and a large proportion are secondary to gastrointestinal perforation. Studies have shown the superiority of the abdominal CT over upright chest radiographs in demonstrating free intraperitoneal air. Spontaneous perforated pyometra is a rare cause of the surgical acute abdomen with free intraperitoneal air. Only 38 cases have been reported worldwide. We report 2 cases of spontaneously perforated pyometra in our hospital's general surgery department. Both underwent exploratory laparotomy: one had a total hysterectomy and bilateral salpingo-oophorectomy, while the other had an evacuation of the uterine cavity, primary repair of uterine perforation and a peritoneal washout. A literature search was conducted and all reported cases reviewed in order to describe the clinical presentations and management of the condition. Of the 40 cases to date, including 2 of our cases, the most common presenting symptoms were abdominal pain (97.5%), fever (37.5%) and vomiting (25.0%). The main indication for exploratory laparotomy was pneumoperitoneum (97.5%). Pyometra is an unusual but serious condition in elderly women presenting with an acute abdomen. A high index of suspicion is needed to make the appropriate diagnosis.

    2012-01-01

    We describe the first reported case of uterine perforation by a cystoperitoneal shunt. The mechanism of this unusual complication is unclear. A 17-year-old patient had a cystoperitoneal shunt for a porencephalic cyst. She presented with recurrent watery vaginal discharge. A pelvic ultrasound examination showed that the uterus had been perforated by the distal tip of the shunt. The cystoperitoneal shunt was converted to a ventriculo-atrial shunt, and the vaginal discharge subsequently resolved. The appearance of light and clear vaginal discharge in a patient with a cystoperitoneal shunt raises the possibility of uterine perforation. This can be confirmed by ultrasound and analysis of the discharge. Removal of the shunt leads to spontaneous closure of the uterine defect.

    Full Text Available Chronically embedded foreign bodies can lead to perforations, mediastinitis, and abscess, amongst a host of other complications. A 20-year-old mentally challenged female presented with “something stuck in her throat,” severe dysphagia, and recurrent vomiting. Initial imaging was unremarkable; however, subsequent imaging and esophagogastroduodenoscopy two weeks later revealed an embedded pork bone. Surgery was performed to remove the bone and fix the subsequent esophageal perforation and esophagus-innominate artery fistula. This case helps reinforce the urgency in removing an ingested foreign body and the ramifications that may arise with chronically embedded foreign bodies.

    Full Text Available Primary repair of traumatic colonic perforation is progressively gaining acceptance as the best method of management. However, when delayed, the risk of infection-related complications may increase. Here, we present a new method of repairing colon perforation in the presence of peritonitis. Acute colon injury was simulated in 22 German shepherd dogs. The dogs were randomly divided into two groups of 11 and after 24 hours they were operated on. The perforations were repaired by subserosal suture technique. In the first group (group A, ileal patch was used. In the other group (group B, the colon was closed by debridement and anastomosis. After 6 weeks, the repairs were assessed on the basis of survival, gross and histological assessments. Nine (82% dogs in group A and six (56% in group B survived. Ileal patch utilization significantly decreased the mortality rate (p < 0.05. The cause of death in two group A dogs and five group B dogs was peritonitis and intra-abdominal abscess formation. None of the surviving dogs showed evidence of anastomotic leakage or breakdown. Small bowel patch used in primary repair of colon injury in the presence of peritonitis may decrease the risk of postoperative infection-related complications and the mortality rate.

    2013-01-01

    Full Text Available Meckel’s diverticulum is the commonest congenital malformation of gastrointestinal tract and represents a persistent remnant of the omphalomesenteric duct. Although it mostly remains silent, it can present as bleeding, perforation, intestinal obstruction, intussusception, and tumours. These complications, especially bleeding, tend to be more common in the paediatric group and intestinal obstruction in adults. Stone formation (lithiasis in Meckel’s diverticulum is rare. We report a case of Meckel’s diverticulum lithiasis which presented as an acute abdomen in an otherwise healthy individual. The patient underwent an exploratory laparotomy which revealed a perforated Meckel’s diverticulum with lithiasis; a segmental resection with end-to-end anastomosis of small bowel was performed. Patient recovery was delayed due to pneumonia, discharged on day 20 with no further complications at 6 months following surgery.

  7. Failure analysis of leakage caused by perforation in an L415 steel gas pipeline

    Directory of Open Access Journals (Sweden)

    Zhiyong Liu

    2017-10-01

    Full Text Available The reasons for the failure of a buried pipeline perforated during construction were investigated by a chemical composition analysis; a metallographic test; macromorphology observation; characterization of the corrosion products by scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray diffraction; field medium characterization; and an analysis of the working conditions. The results revealed that the material composition and organization of the steel pipe conformed to API Specification 5CT. However, the reason for the perforation of the L415 steel pipe was an ultrahigh growth rate of pitting corrosion, as high as 14 mm per year. We confirmed that the synergistic effect of a high partial pressure of oxygen introduced by an improper packing process and concentrated Cl− in the corrosion product layer, which originated from groundwater with a high salt concentration that was used for the water pressure test, were responsible for the failure process.

    Full Text Available Mucormycosis is a rare and often fatal opportunistic infection that especially occurs in immunocompromised patients. Primary gastrointestinal infection is uncommon and accounts for only approximately 7% of all cases of mucormycosis but it is associated with an 85% mortality rate due to perforation and massive bleeding. Very few cases of gastrointestinal mucormycosis in an immunocompetent host have been reported. We describe a case of gastric necrosis and massive bleeding due to fulminant invasive mucormycosis.

    Full Text Available We present a case of 2-year-old boy with long term dysuria and intermittent incontinence, and new onset of fever and headache. Significant past medical history includes congenital hydrocephalus with a ventriculoperitoneal shunt placement two years prior to consult. On physical examination, a tubular structure was noted underneath the prepuce suspected to be the distal tip of ventriculoperitoneal shunt, which was confirmed by kidney, ureter and bladder (KUB X-ray and CT scan. Patient was treated with a novel approach of extraperitoneal removal of ventriculoperitoneal shunt distal tip with cystorrhaphy via a low transverse pfannenstiel incision, separate left ventriculostomy tube insertion and complete removal of ventriculoperitoneal shunt from the right ventricle.

    Many of the abdominal foreign bodies are due to accidental ingestion. Our objective in this case report is to emphasize the importance of the enquiry about the foreign body in the differential diagnosis of acute abdominal pain. According to our knowledge, this is the first report of bowel perforation caused by paper ingestion. A 14-year-old boy with abdominal pain underwent exploratory laparotomy and was found to have abdominal pus and ileal perforation. A crumpled paper was found at the site of perforation. Postoperative enquiry revealed that the patient had ingested 10 crumpled papers. We highlight that recording the history is an important aspect in the management of patients with acute abdominal pain and that foreign bodies should be included in its differential diagnosis.

    Full Text Available Background: Sepsis related-multiple organ dysfunction is associatedwith ileum injury. We aimed to determine the causes ofileal injury in two models of microbial sepsis resulted from infectionwith Aeromonas hydrophila or its endotoxin. We alsoevaluated the protective effect of phytic acid.Methods: Thin sections of ileum from 60 Swiss male mice incontrol, bacteria-infected or lipopolysaccharides (LPS andbacteria-infected or LPS-infected co-administered with phyticacid were subjected to histopathological and TdT-mediateddUTP nick-end labeling (TUNEL assay for apoptotic cellsdetection while ultra thin sections were stained with uranylacetate and lead citrate for cytological changes examination.Also, ileum images were exposed to the image analysis softwareto determine some related morphometric measures.Results: Necrosis and apoptosis were observed in ileum injuryin both examined sepsis models. The ileum injury was moresevere in LPS model. Phytic acid showed the ability to attenuateileum injury in Aeromonas hydrophila and its endotoxinmodels of sepsis after four weeks administration where itssupplementation significantly minimized the histopathologicaland cytological complications and morphometric alterationsresulted from the injury.Conclusion: The protective effects of phytic acid may becaused by increased mucous secretion, decreased apoptoticindex, attenuating the inflammatory and lymphocytic cellscount or increasing the renewal of the crypt cells and villousepithelial cells proliferation.

    A bezoar is a mass formed because of the accumulation of indigestible material in the stomach and/or small intestine. Bezoars are rare but occasionally occur with acute abdomen findings. Bezoars form as a result of changes in the gastrointestinal system anatomy and physiology and repetitive exposure to the ingested material. These materials can include vegetables with high fiber content (phytobezoars), non-animal origin fats, hair (trichobezoars), or drugs such as anti-acids (pharmobezoars). Gastric bezoars frequently occur after gastric surgery. Psychiatric disorders such as trichotillomania (an irresistible urge to remove and swallow one's own hair) are frequently the underlying reason in patients without a history of gastric surgery. In this article, we presented a giant gastric trichobezoar obstructing outlet and causing closed-perforation and abscess formation of gastric fundus in a 30-year-old woman.

  16. Malignant lymphoma incidentally diagnosed due to the perforation of the small intestine caused by a fish bone: A case report

    Directory of Open Access Journals (Sweden)

    Masatsugu Hiraki

    Full Text Available Introduction: The ingestion of a foreign body is relatively common. However, it rarely results in the perforation of gastrointestinal tract. We herein report an unusual case of malignant lymphoma incidentally diagnosed after the perforation of the small intestine by a fish bone. Presentation of case: A 90-year-old woman was admitted to our hospital because of abdominal pain and vomiting. Abdominal computed tomography demonstrated free air and ascites in the abdominal cavity. In the pelvic cavity, a radiopaque linear shadow about 35 mm in diameter was shown in the small intestine, and the stricture was exposed to the abdominal cavity. Therefore, a diagnosis of perforation of the small intestine due to ingestion of a foreign body and panperitonitis was made. Emergent laparotomy was performed. The intraoperative findings revealed perforation of the small intestine with a fish bone in the jejunum. Local inflammation at the perforation site was seen, and circulated wall thickness was observed at the distal side of the jejunum. Partial resection of the jejunum and anastomosis of jejuno-jejunostomy was performed. A pathological examination and immunohistochemical study of the resected specimen resulted in a diagnosis of malignant lymphoma of follicular lymphoma Grade 1. Discussion: It is very difficult to identify the existence malignancy accompanied with gastrointestinal perforation with ingestion of a foreign body. Conclusion: In cases suspected of involving malignancy, careful observation during surgery is needed in order to avoid missing the accompanying malignancy.

    Full Text Available The authors describe a case of abdominal angiostrongyliasis in an adult patient presenting acute abdominal pain caused by jejunal perforation. The case was unusual, as this affliction habitually involves the terminal ileum, appendix, cecum or ascending colon. The disease is caused by the nematode Angiostrongylus costaricensis, whose definitive hosts are forest rodents while snails and slugs are its intermediate hosts. Infection in humans is accidental and occurs via the ingestion of snail or slug mucoid secretions found on vegetables, or by direct contact with the mucus. Abdominal angiostrongyliasis is clinically characterized by prolonged fever, anorexia, abdominal pain in the right-lower quadrant, and peripheral blood eosinophilia. Although usually of a benign nature, its course may evolve to more complicated forms such as intestinal obstruction or perforation likely to require a surgical approach. Currently, no efficient medication for the treatment of abdominal angiostrongyliasis is known to be available. In this study, the authors provide a review on the subject, considering its etiopathogeny, clinical picture, diagnosis and treatment.Os autores descrevem caso de angiostrongilíase abdominal em doente adulto que se manifestou como abdômen agudo devido à perfuração de alça jejunal, evento raro, uma vez que esta afecção geralmente envolve o íleo terminal, apêndice, ceco ou cólon ascendente. A doença é causada pelo nematódeo Angiostrongylus costaricensis cujos hospedeiros definitivos são roedores silvestres e os hospedeiros intermediários são caracóis e caramujos. A infecção em humanos é acidental e ocorre pela ingestão de secreção mucóide destes invertebrados presentes em vegetais ou por contato direto com o muco. A angiostrongilíase abdominal é clinicamente caracterizada pela presença de febre prolongada, anorexia, dor no quadrante inferior direito do abdômen e eosinofilia periférica. Embora a doença seja de

    After a penetrating injury of the eye following a car accident the driver demanded accurate investigations by the Institute for Legal Medicine of Zurich concerning the security of the equipment, especially the airbag. This led to an astonishing explication of the mechanism of the injury, not without consequences for safety measures for drivers and front seat passengers in air bag equipped cars. Due to a relatively harmless accident, the driver suffered from a severe penetrating injury of the right eye after the airbag deployed. The front seat passenger, having the seat belts fastened, was not injured. The accident was investigated by the Institute of Legal Medicine of Zurich. The analysis of the accident showed that the airbag had deployed properly. The cover of the airbag showed no defects of substance. With the precise examination of the interior of the car a broken tobacco pipe came to light. In this case not the airbag itself but a tobacco pipe held in the hand by the driver during the airbag ignition caused a severe injury of the eye. This case report illustrates the hazard of having any rigid object between the occupant and the deploying air bag. In conclusion, the drivers and front seat passengers of an airbag equipped car can only profit from the considerable security gain, if they know about these risks and adapt their behaviours to the new surroundings, but also the car manufactures have to instruct the customers properly.

    Introduction Although diverticular disease of the duodenum and colon is frequent, the jejuno–ileal diverticulosis (JOD) is an uncommon entity. The perforation of the small bowel diverticula can be fatal due to the delay in diagnosis. Presentation of case We report the case of a 79-year-old man presenting with generalized abdominal pain and altered bowel habits. Physical examination revealed a severe diffuse abdominal pain. A CT scan of the abdomen and pelvis with oral contrast showed thickening of the distal jejunal loop and thickening and infiltration of the mesenteric fat and the presence of free air in the mesentery suggesting a possible perforation adjacent to the diverticula. A midline laparotomy was performed. The jejunal diverticula were found along the mesenteric border. Forty centimeters of the jejunum were resected. Histopathology report confirmed the presence of multiple jejunual diverticula, and one of them was perforated. The patient tolerated the procedure and the postoperative period was uncomplicated. Discussion The prevalence of small intestinal diverticula ranges from 0.06% to 1.3%. The etiopathogenesis of JOD is unclear, although the current hypothesis focuses on abnormalities in the smooth muscle or myenteric plexus, on intestinal dyskinesis and on high intraluminal pressures. Diagnosis is often difficult and delayed because clinical symptoms are not specific and mainly imaging studies performs the diagnosis. Conclusion Because of the relative rarity of acquired jejuno–ileal diverticulosis, the perforation of small bowel diverticulitis poses technical dilemmas. PMID:25841158

    Full Text Available The urethra is a usual site of introduction of foreign bodies for autoerotic stimulation. We present an unusual case of bladder perforation caused by foreign body that was self-inserted in the urethra and consequently slipped inside the bladder in a 29-year-old female patient with psychiatric disease. The patient was referred to our department for macroscopic hematuria and abdominal pain. Imaging studies revealed the presence of a foreign body in the pelvic area which had perforated the left lateral wall of the bladder. The foreign body was removed via open cystotomy. In psychiatric patients hematuria and pelvic pain may result from insertion of a foreign body in the bladder usually during masturbation.

    Full Text Available Abstract Background Carcinoma of the colon may present with perforation proximal to the site of malignancy. Caecum is the commonest site of perforation if the ileocecal valve is patent and the jejunal and ileal perforations are very rare. Case presentation A 35 year male presented with intestinal obstruction. Emergency laparotomy revealed carcinoma of the transverse colon with multiple pinpoint perforations along antimesenteric border of ileum, which were wrapped with omentum, and no peritoneal contamination was present. Extended right hemicolectomy with jejunocolic anastomosis was done. Patient made uneventful recovery in postoperative period and was treated with adjuvant chemotherapy. Conclusion Patients with colonic carcinoma and incompetent ileocecal valve may present with intestinal perforation. Increased intraluminal pressure and closed loop obstruction may lead to ischemia and perforation of the small bowel.

    Computed tomography (CT) is useful for evaluating esophageal foreign bodies and detecting perforation. However, when evaluation is difficult owing to the previous use of barium as a contrast medium, 3-dimensional CT may facilitate accurate diagnosis. A 49-year-old man was transferred to our hospital with the diagnosis of esophageal perforation. Because barium had been used as a contrast medium for an esophagram performed at a previous hospital, horizontal CT and esophageal endoscopy could not be able to identify the foreign body or characterize the lesion. However, 3-dimensional CT clearly revealed an L-shaped foreign body and its anatomical relationships in the mediastinum. Accordingly, we removed the foreign body using an upper gastrointestinal endoscope. The foreign body was the premaxillary bone of a sea bream. The patient was discharged without complications.

    An extensive perforating internal root resorption accompanied by apical periodontitis and odontogenic sinus mucositis was detected on preoperative cone-beam computed tomographic scans in a first maxillary molar. After the chemomechanical debridement of the root canals, calcium hydroxide was placed as a temporary dressing for 7 days. Mineral trioxide aggregate was used to fill the perforation site with the aid of a surgical microscope. At the next visit, the root with the resorption defect was filled with warm vertical compaction of gutta-percha. A control cone-beam computed tomographic scan acquired 6 months after the endodontic treatment revealed complete resolution of the sinus retention cyst. Moreover, the patient's frequent otolaryngologic disturbances ceased. The tooth was functional with satisfactory clinical and radiographic results after 12 months. Based on the results of this case, successful repair of an extensive, perforating internal resorption with mineral trioxide aggregate may lead to complete resolution of apical periodontitis and maxillary sinus retention cyst.

    Full Text Available Intestinal atresia type III B (apple peel and gastroschisis are both congenital malformations who require early surgical correction in neonatal age. Their association is very rare. We present the case of a full term infant with partial apple peel ileal atresia and a small defect of the anterior abdominal wall, complicated by in utero intestinal perforation and subsequent meconial peritonitis. We observed a partial atresia of small intestine, with involvement of terminal ileus savings of jejunum and a large part of the proximal ileum, small anterior abdominal wall defect with herniation of few bowel loops, intestinal malrotation. Paralytic ileus and infections are the main causes of morbidity and mortality at neonatal age. In our case, in spite of the mild phenotype, prognosis has been complicated by the onset of functional bowel obstruction, caused by chemical peritonitis resulting from contact with either amniotic fluid and meconium.

    Full Text Available Intussusception is defined as the telescoping of a segment of the gastrointestinal tract (intussusceptum into an immediately adjacent distal bowel (intussuscipiens. Intussusception is a relatively rare cause of intestinal obstruction in adults. Unlike in children, a lead point is present in 90% of adult cases. The most common causes of small bowel intussusception are benign, usually hamartomas, lipomas, inflammatory polyps, adenomas and leiomyomas, in contrast to the large intestine where malignant tumors, usually adenocarcinomas, are more common. The clinical presentation of adult intussusception is non-specific with variable manifestations, predominantly those of intestinal obstruction, often making the diagnosis a challenge. The onset of symptoms may be acute, intermittent or chronic. We present a rare case of an ileal fibroma presenting with intussusception. A 43-year-old woman presented to our outpatient clinic with a history of recurrent abdominal pain. The clinical presentation and CT scan findings led to the diagnosis of ileoileal intussusception. Subsequently she underwent laparotomy which revealed an ileal fibroma as the lead point of the intussusception. Surgical exploration remains essential for diagnosis and treatment since in the majority of cases a pathologic lead point is identified. Ileal fibroma is an uncommon benign neoplasm of the small bowel and must be considered in the differential diagnosis for small bowel intussusception.

    Symptomatic penetration of the inferior vena cava (IVC) wall reportedly occurs in 0.3% of patients in whom a filter has been implanted, and it causes injury to the adjacent structures (Bogue et al. in Pediatr Radiol 39(10):1110–1113, 1; Brzezinski et al. in Burns 32(5):640–643, 2). We succeeded in the endovascular repair of perforation of the IVC wall occurring during the retrieval of a penetrated Gunther tulip vena cava filter (Cook, Bjaeverskov, Denmark) after long-term implantation.

    Full Text Available Introduction. Inguinal hernias are very common in men. A clinical exam can do the diagnosis easily. But bowel perforation inside an inguinal hernia caused by a directly blunt trauma is rare and can have important consequences. Up to now, there have been a few case reports that described blunt injury to the inguinal area causing traumatic perforation of the bowel in the inguinal hernia. Case Report. We present a case of a 45-year-old Eastern European man with a small perforation of ileal bowels and a peritonitis after direct blunt trauma to the inguinal hernia region, with no inguinal hernia known by the patient, and show how the diagnosis can be difficult. Conclusion. This case shows that external forces, that may seem too trivial to cause intraperitoneal injury, can cause significant injury when applied to a patient with a hernia and shows how a careful examination, with the help of an abdominal CT scan, is important even if the patient do not seem to have an inguinal hernia.

    Ileal dysgenesis is an uncommon condition of unknown etiology occurring in the distal ileum in the region of the vitelline duct. The CT appearance of this lesion, although not previously described to our knowledge, is characteristic. We report a patient with ileal dysgenesis who had an abdominal CT scan to evaluate chronic iron deficiency anemia and protein-losing enteropathy. Recognition of this lesion by pediatric radiologists is important; so that surgical treatment, which is simple and effective, can be initiated quickly. (orig.)

    the Bacteroides-Prevotella-Porphyrmonas group (P = 0.033), whereas it reduced (P = 0.027) fecal n-butyrate concentration. Pectin infusion reduced (P = 0.005) ileal gene copy number of the C. leptum cluster. In conclusion, ileal bacterial populations and fermentation patterns are susceptible to changes in the intestinal availability of Ca and P as well as to the supply of pectin as a fermentable substrate. Greater intestinal Ca availability decreased the numbers of some gram-positive bacteria, whereas greater P availability in the small intestine caused by phytase activity enhanced the growth of strictly anaerobic bacteria.

    Goal of this research program is to create ultrathin organic membranes that possess uniform and adjustable pores ( < 7[angstrom] diameter). Such membranes are expected to possess high permeation selectivity (permselectivity) and high permeability, and to provide the basis for energy-efficient methods of molecular separation. Work carried out has demonstrated feasibility of using perforated monolayer''-based composites as molecular sieve membranes. Specifically, composite membranes derived from Langmuir-Blodgett multilayers of the calix[6]arene-based surfactant shown below plus poly[l-(trimethylsilyl)-l-propyne] (PTMSP) were found to exhibit sieving behavior towards He, N[sub 2] and SF[sub 6]. Results of derivative studies that have also been completed are also described in this report.

    Full Text Available Background:peptic ulcers were earlier believed to be caused by dietary factors, gastric acid, and stress. However, in 1983, Warren and Marshall identified the correlation between Helicobacter pylori (H. pylori and peptic ulcers. It is now well established that most of the peptic ulcers occur as a result of H. pylori infection. But the co-relation between perforated peptic ulcer and H. pylori infection is not yet fully established. Aims and objectives : to study the prevalence of H. pylori infection in patients with perforated peptic ulcer. Materials and methods: this was a prospective study carried out in all cases of perforated peptic ulcer reporting in surgical wards of a medical college during 2008-2010. A total of 50 cases, presenting as acute perforation of duodenum and stomach during this period, formed the study group. After resuscitation, all the cases were subjected to emergency exploratory laparotomy. The exact site of perforation was identified, biopsy was taken from the ulcer margin from 2-3 sites and the tissue was sent for H. pylori culture and histopathological examination. Simple closure of perforation, omentoplasty, thorough peritoneal lavage and drainage was carried out. Results: out of the 50 cases of perforated peptic ulcer, 38 happened to be males, and only 12 were females. The age of the patients ranged from 20 to 70 years. All the patients underwent only emergency laparotomy. As many as 46 cases (92% turned out to be positive for H. pylori and only four cases (8% were negative for this infection. Postoperatively, patients who were found to be positive for H. pylori were put on anti-H. pylori treatment. Conclusion: there was a high prevalence of H. pylori infection in patients with perforated gastroduodenal ulcers.

    A 58-year-old man was referred to our hospital with high fever and anuria. Since undergoing a total pelvic exenteration due to bladder-invasive sigmoid colon cancer, urinary tract infections had frequently occurred. We treated with the construction of a bilateral percutaneous nephrostomy (PCN), and chemotherapy. Although we replaced the PCN with a single J ureteral catheter after an improvement of infection, urinary infection recurred because of an obstruction of the catheter. Urological examinations showed that an ileal conduit-ureteral reflux caused by kinking of the ileal loop was the reason why frequent pyelonephritis occurred. We decided to resect the proximal segment to improve conduit-ureteral reflux for the resistant pyelonephritis. After the surgery, the excretory urogram showed improvement and the urinary retention at the ileal conduit disappeared. Three years after the operation, renal function has been stable without episodes of pyelonephritis. Here we report a case of open repair surgery of an ileal conduit in a patient with severe urinary infection.

    Described in this study is a surgical concept that supports the "consider and use a pedicled perforator flap whenever possible and indicated" approach to reconstruct a particular skin defect. The operation is entirely free-style; the only principle is to obtain a pedicled perforator flap...... to reconstruct the defect. The perforators are marked with a hand-held Doppler probe and multiple flaps are designed. The appropriate flap is elevated after identifying the perforator(s). Dissection of the perforator(s) or complete incision of the flap margins are not mandatory if the flap is mobilized...... adequately to cover the defect. Defects measuring 3 x 3 cm up to 20 x 20 cm at diverse locations were successfully reconstructed in 20 of 21 patients with 26 flaps. Pedicled perforator flaps offer us reliable and satisfactory results of reconstruction at different anatomic territories of the body. It sounds...

    A 55-year-old man with hepatitis B virus antigen-positive liver cirrhosis was admitted to our hospital with anal bleeding. Colonoscopy revealed blood retention in the entire colon, but no bleeding lesion was found. Computed tomography images showed that vessels in the ileum were connected to the right testicular vein, and we suspected ileal varices to be the most probable cause of bleeding. We immediately performed double balloon enteroscopy, but failed to find any site of bleeding owing to the difficulty of fiberscope insertion with sever adhesion. Using a balloon catheter during retrograde transvenous venography, we found ileal varices communicating with the right testicular vein (efferent vein) with the superior mesenteric vein branch as the afferent vein of these varices. We performed balloon occluded retrograde transvenous obliteration by way of the efferent vein of the varices and have detected no further bleeding in this patient one year after treatment.

    Full Text Available Secondary symptomatic gastrointestinal metastases from lung primary tumor are rare. They can cause a variety of clinical conditions such as perforation, obstruction and bleeding. Intestinal perforations of intestinal metastases have a very poor prognosis. We present a case of a patient with metastatic lung cancer who presents with intestinal perforation and pneumoperitoneum. A 67 year old male, immunosuppressed and smoker is diagnosed with acute abdomen secondary to perforation of a tumor of the terminal ileum, as well as three other similar injuries. Resection and anastomosis. The patient died two months after surgery. The final pathological diagnosis supports epidermoidide poorly differentiated lung carcinoma. It was concluded that given an intestinal perforation in a patient diagnosed with lung carcinoma, it shouldn´t be excluded the metastases origen . Surgery is a purely palliative procedure.

    Full Text Available Duplications of the alimentary tract are infrequent anomalies. They are most frequently located in the terminal ileum, and majority of them became symptomatic before the age of 2. Presenting symptoms may include abdominal mass, intestinal obstruction, intussusception, rectal bleeding, and abdominal pain. Preoperative diagnosis is usually difficult, intra-abdominal duplications are usually diagnosed during surgical explorations of above complications. We presented a 12-year-old girl with asymptomatic ileal duplication cyst associated with non-complicated acute appendicitis, whose imaging studies at admission were compatible with complicated perforated appendicitis.

    Microbiota plays a role in the release and absorption of nutrients from feed components, thereby affecting digesta composition and moisture content of the excreta. The objective of the current study was to determine the effects of 5 different diets varying in ingredients (medium-chain fatty acids, nonstarch polysaccharides, and starch) on the microbiota composition of ileal digesta of broiler chickens and excreta DM content. Each treatment was repeated 6 times in cages each containing 18 Ross 308 broilers, with growth performance measured from 0 to 34 d of age and excreta DM and ileal microbiota composition analyzed at 34 d of age. Microbiota composition was evaluated using a novel ribosomal RNA microarray technology containing 370 different probes covering various genera, groups of microbial species, and individual species of the chicken gut microbiota, of which 321 had a signal above the background threshold. Replacing part of the animal fat and soybean oil in the wheat-based diet with medium-chain fatty acids (MCFA; 0.3% C10 and 2.7% C12) improved feed efficiency compared with the other dietary treatments. This coincided with a suppression of gram-positive bacteria belonging to the phylum of the Firmicutes, including Lactobacillus species, and species belonging to the family of the Enterococcaceae and Micrococcaceae, whereas the gram-negative bacteria belonging to the family of the Enterobacteriaceae were promoted. None of the other diets used in the present study notably changed the ileal digesta bacteria composition. Excreta DM content was not affected by dietary treatment. The variation between individual birds per dietary treatment was more pronounced than variation caused by feed composition, with the exception of the digesta microbiota of the birds fed the MCFA diet. It is concluded that a diet with MCFA significantly changes the ileal microbiota composition, whereas the effect of the other diets on the composition of the microbiota and excreta DM content

    During contrast enema, perforation into the retroperitoneal space can be differentiated from perforation into the peritoneum and perforation into the intestinal wall associated with formation of barium granulomas or submucosal spreading of the contrast medium. Other special forms are perforation with contrast medium embolism of diverticula; of the processus vermiformis; penetration of contrast medium into fistulous systems and from the operated areas. Risk factors are: balloon catheter, intestinal tubes with a hard tip, preternatural anus, excessive enema pressure, contrast medium additions, preceding manipulations, intestinal diseases, advanced age and delegation of manipulations to assistants and unskilled staff. Children are particularly at risk. (orig.) [de

    Spontaneous uterine rupture and generalized peritonitis caused by pyometra occurs rarely with high morbidity and mortality. A correct and definite diagnosis can be made with laparotomy or laparoscopy. The clinical findings of perforated pyometra are similar to perforation of the gastrointestinal tract and gynecologic symptoms are less frequent, which makes preoperative diagnosis difficult. We report a case of a patient aged 82 years who underwent surgery for spontaneous uterine rupture and generalized peritonitis as a result of pyometra. PMID:28913055

    Injury to the small intestine from pelvic irradiation increases in frequency when extended treatment fields are utilized and when radiation therapy follows a major abdominal operation. Recommended surgical correction of such injury has been intestinal bypass to avoid the excessive morbidity and mortality from anastamotic leaks associated with primary resection and anastomosis. Since 1980, eight patients with extensive ileal injury secondary to irradiation have been seen at the Naval Hospital Bethesda, Maryland. All patients had previously undergone an abdominal operation and three patients had irradiation utilizing extended fields. In all cases, right hemicolectomy and extended ileal resection were performed with primary anastamosis of the ileum to the ascending colon or the transverse colon. Operating time averaged 4 1/2 hr utilizing hand closure anastomoses and 2 1/2 hr with stapled anastomoses. All patients received postoperative hyperalimentation and six of eight patients received preoperative hyperalimentation. One operative death occurred in a patient with intestinal perforation who required multiple resections. The remaining seven patients experienced no serious complications and had rapid return of bowel function. Our experience indicates that wide ileal resection with right hemicolectomy and primary reanastomosis is an acceptable alternative to intestinal bypass for the treatment of severe irradiation injury, especially when performed with gastrointestinal stapling devices

    2009-04-02

    INTRODUCTION: Stercoral perforation is a rare cause of perforation. This is the first reported case where a partial eating disorder (ED) is the primary causative differential. CASE PRESENTATION: We present the case of a 17-year-old girl who presented to her local Emergency Department with a 24-h history of left-sided abdominal pain. She subsequently deteriorated and a computed tomography scan of her abdomen showed gross distension of the large bowel with a sigmoid perforation. She underwent total colectomy with end ileostomy. Histology reported stercoral perforation but normal bowel ganglia. While an inpatient she was reviewed by the Psychiatric team who were concerned she was suffering from a partial ED. CONCLUSION: This case highlights the importance of a multidisciplinary approach in optimally treating patients such as these. Aggressive medical management with involvement of a psychiatric team and dietetics addresses any underlying causative psychiatric issues and helps prevent recurrence.

    The effects of cellulose and the interindividual variations on the transit time in the small intestine remain unclear, but no previous study has to date taken these factors into sufficient consideration. We assessed the oro-ileal transit time and the recovery percentage of cellulose in the terminal ileum looking at interindividual variations. Seven healthy males received 100 mL of a dietary fiber-free basal diet with 5 g cellulose and 5 g of polyethylene glycol 4000. The ileal contents were aspirated every 30 min via an experimental tube placed in the terminal ileum to assess the oro-ileal transit time and the recovery percentage of cellulose. The mean percentage (with standard deviation) of the amounts of cellulose collected in the terminal ileum was 98.4%+/- 16.5% (ranging from 67.4% to 114.5%) with a coefficient variation of 16.8%. The average times (in hours) taken for 20%, 40%, 60%, and 80% of cellulose to reach the terminal ileum were 5.5 +/- 1.1, 6.7 +/- 0.7, 8.5 +/- 1.3, and 8.8 +/- 1.2, respectively, with large interindividual variations. In conclusion, the averaged recovery percentage of cellulose in the terminal ileum was approximately 100%, in accordance with the present generally accepted definition of dietary fiber. However, there were large interindividual variations in the oro-ileal transit time and the percentage of cellulose recovered.

    Full Text Available Colon perforation is an uncommon event usually caused by malignancy, diverticular disease, amoebic colitis, steroid therapy, trauma and ulcerative colitis, but stercoral perforation is very rare. Severe chronic constipation is considered to be the main causative factor in development of stercoral perforation of colon. Sometimes it can also produce catastrophic complications like colonic obstruction, faecal peritonitis and septicaemia. We report a rare case of sigmoid colonic perforation with faecal peritonitis and pneumoperitonium due to faecaloma which was diagnosed after exploratory laparotomy.

    To evaluate the usefulness of CT for assessing the location and cause of pathologic gastrointestinal perforation. A retrospective analysis of abdominal CT was performed in 27 perforations of 26 patients with underlying gastrointestinal pathology. Fifteen benign and 12 malignant perforations consisted of five gastric cancers, one gastric ulcer, ten duodenal bulb ulcers. two bowel adhesions, one jejunal metastasis from lung cancer, one ileocolic Crohn's disease, one radiation colitis and six colon cancers. CT scans were evaluated for (1) diagnosis of bowel perforation, (2) assessment of the cause and site of perforation, and, in particular, differentiation between benignancy and malignancy, and (3) complications and their extent. CT easily detected varying amounts of free air or fluid collection, and infiltration or abscess formation adjacent to the main lesion, and the diagnosis of gastrointestinal perforation was therefore easy. In 11 of the 12 malignancies (92%), primary tumor was diagnosed, but detection of the site of perforation was possible in only seven cases(7/12, 58%). The 15 benign lesions revealed nonspecific CT findings, and the perforation site could be presumed in six (6/15, 40%). In one case of Crohn's disease, the primary cause was visualized. Among six colonic cancers, four pericolic abscesses and two fistulas to adjacent organs were found, but there was no evidence of diffuse peritonitis. CT was helpful to lead to optimal treatment of pathologic gastrointestinal On CT the detectability of perforation, primary benign or malignant lesion, perforation site and extent of complication was high, and this modality was therefore a useful indicator of the optimal treatment for pathologic gastrointestinal perforations.=20.

    Colonic perforation is a lethal condition presenting high morbidity and mortality in spite of urgent surgical treatment. This study investigated the surgical outcome of patients with colonic perforation associated with retroperitoneal contamination. Retrospective analysis was performed for 30 patients diagnosed with colonic perforation caused by either inflammation or ischemia who underwent urgent surgical treatment in our facility from January 2005 to December 2014. Patient characteristics were analyzed to find risk factors correlated with increased postoperative mortality. Using the Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) audit system, the mortality and morbidity rates were estimated to verify the surgical outcomes. Patients with retroperitoneal contamination, defined by the presence of retroperitoneal air in the preoperative abdominopelvic CT, were compared to those without retroperitoneal contamination. Eight out of 30 patients (26.7%) with colonic perforation had died after urgent surgical treatment. Factors associated with mortality included age, American Society of Anesthesiologists (ASA) physical status classification, and the ischemic cause of colonic perforation. Three out of 6 patients (50%) who presented retroperitoneal contamination were deceased. Although the patients with retroperitoneal contamination did not show significant increase in the mortality rate, they showed significantly higher ASA physical status classification than those without retroperitoneal contamination. The mortality rate predicted from Portsmouth POSSUM was higher in the patients with retroperitoneal contamination. Patients presenting colonic perforation along with retroperitoneal contamination demonstrated severe comorbidity. However, retroperitoneal contamination was not found to be correlated with the mortality rate.

    Ileal atresia is a rare congenital malformation which affects a small percentage of the population, with an incidence of 1 in 5000 cases. It may be suspected and diagnosed by ultrasound at the end of the second and third trimester. Obstetrical and surgical consultation is the key to success here. Eliminating a systemic disease with poor prognosis, fighting to reduce premature births and immediately entrusting the child to the surgeon are the main objectives to achieve. During surgery, the surgeon will determine the type of atresia, its location, single or multiple areas of occlusion and its length; thus surgery depends on etiology. Our study reports an interesting clinical case of ileal atresia diagnosed antenatall.

    Full Text Available Jejunal diverticulosis is a rare case that is diagnosed incidental. Although it is generally asymptomatic, it can cause non-spesific symptoms like stomachache, nausea, diarrhoea, malabsorption, bleeding, obstruction and / or perforation. Perforated jejunal diverticulitis is a very rare acute abdomen cause. The acute complications of jejunal diverticulosis can be cause of significant morbidity and mortality especially in old patients. In this text, we report a 81 year old woman case that was operated emergently because of perforated jejunal diverticulitis and was lost in postoperation term because of multiple organ failure.

    Full Text Available The majority of accidentally ingested foreign bodies is excreted from the gastrointestinal (GI tract without any complications. Sometimes sharp foreign bodies – like chicken and fish bones – can lead to intestinal perforation and may present insidiously with a wide range of symptoms and, consequently, different diagnoses. We report the case of a 59-year-old woman presenting with fever and a 1-month history of vague abdominal pain. Computed tomography (CT showed the presence of a hyperdense linear image close to the gastric antrum surrounded by a fluid collection and free peritoneal air. At laparotomy, a 4-cm rabbit bone fragment covered in inflamed tissue was detected next to a gastric wall perforation. Rabbit bone fragment ingestion, even if rarely reported, should not be underestimated as a possible cause of GI tract perforation.

    Full Text Available In 2010, researchers reported that the two US-licensed rotavirus vaccines contained DNA or DNA fragments from porcine circovirus (PCV. Although PCV, a common virus among pigs, is not thought to cause illness in humans, these findings raised several safety concerns. In this study, we sought to determine whether viruses, including PCV, could be detected in ileal tissue samples of children vaccinated with one of the two rotavirus vaccines. A broad spectrum, novel DNA detection technology, the Lawrence Livermore Microbial Detection Array (LLMDA, was utilized, and confirmation of viral pathogens using the polymerase chain reaction (PCR was conducted. The LLMDA technology was recently used to identify PCV from one rotavirus vaccine. Ileal tissue samples were analyzed from 21 subjects, aged 15–62 months. PCV was not detected in any ileal tissue samples by the LLMDA or PCR. LLMDA identified a human rotavirus A from one of the vaccinated subjects, which is likely due to a recent infection from a wild type rotavirus. LLMDA also identified human parechovirus, a common gastroenteritis viral infection, from two subjects. Additionally, LLMDA detected common gastrointestinal bacterial organisms from the Enterobacteriaceae, Bacteroidaceae, and Streptococcaceae families from several subjects. This study provides a survey of viral and bacterial pathogens from pediatric ileal samples, and may shed light on future studies to identify pathogen associations with pediatric vaccinations.

    Spontaneous perforation of the uterus is rare, its incidence being about 0.01%-0.05%. We report a rare case of diffuse peritonitis caused by spontaneously perforated pyometra. A 63-year-old woman with severe abdominal pain was admitted to our hospital. Laparotomy was performed because of the suspicion of gastrointestinal perforation with generalized peritonitis. At laparotomy, about 900 mL of pus was found in the peritoneal cavity. There were no abnormal findings in the alimentary tract, liver, or gallbladder. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Pathological investigation of the surgical specimen revealed endometritis and myometritis of the uterus; but there was no evidence of malignancy, and the cervical canal was patent. Although spontaneously perforated pyometra is rare, a perforated pyometra should therefore also be considered when elderly women present with acute abdominal pain.

    2011-08-01

    Full Text Available Jejunal diverticulosis is a rare entity with variable clinical and anatomical presentations. Although there is no consensus on the management of asymptomatic jejunal diverticular disease, some complications are potentially life-threatening and require early surgical treatment. Small bowel perforation secondary to jejunal diverticulitis by enteroliths is rare. The aim of this study was to report a case of small intestinal perforation caused by a large jejunal enterolith. An 86-year-old woman was admitted with signs of diffuse peritonitis. After initial fluid recovery the patient underwent emergency laparotomy. The surgery showed that she had small bowel diverticular disease, mainly localized in the proximal jejunum. The peritonitis was due to intestinal perforation caused by an enterolith 12 cm in length, localized inside one of these diverticula. The intestinal segment containing the perforated diverticulum with the enterolith was removed and an end-to-end anastomosis was done to reconstruct the intestinal transit. The patient recovered well and was discharged from hospital on the 5th postoperative day. There were no signs of abdominal pain 1 year after the surgical procedure. Although jejunal diverticular disease with its complications, such as formation of enteroliths, is difficult to suspect in patients with peritonitis, it should be considered as a possible source of abdominal infection in the elderly patient when more common diagnoses have been excluded.

    Full Text Available Objective: Postoperative pouch bleeding is a rare but detrimental complication following ileal pouch surgery. It is usually self-limited, however continuous bleeding requires inter- vention. There is limited published data on its management. Design: Ileoscopy via stoma for loop ileostomy and pouchoscopy via anus for ileal pouch were performed under sedation for the purpose of diagnosis and management of postop- erative bleeding. Results: Ileoscopy demonstrated a large, long blood clot in the lumen of efferent limb, but no sign of active bleeding was identified. Pouchoscopy showed that lumen of pouch body as well as afferent limb was filled with maroon-colored liquid stool. Pouch and neo-terminal ileum mucosa was normal. Two dislodged staples at the anastomotic line with sharp tips towards the lumen were found, with activating bleeding at one site. The staples were re- moved by biopsy forceps, and active bleeding was successfully controlled by the deploy- ment of one endoclip. Conclusions: We reported the first case that postoperative pouch bleeding, which was caused by dislodged staples, was successfully managed by endoscopic removal of the staples com- bined with clipping. Resumo: Objetivo: O sangramento pós-operatório da bolsa ileal é uma complicação rara, mas prejudi- cial após abordagem cirúrgica da bolsa ileal. Esse sangramento é geralmente autolimitado, porém, requer intervenção quando contínuo. Não há dados publicados sobre o tratamento. Método: Ileoscopia através de estoma para ileostomia em alça e endoscopia via ânus para a bolsa ileal foram realizadas sob sedação para diagnóstico e tratamento do sangramento pós-operatório. Resultados: A ileoscopia demonstrou um grande e longo coágulo sanguíneo no lúmen do ramo eferente, mas nenhum sinal de sangramento ativo foi identificado. A endoscopia da bolsa ileal mostrou que os lumens do corpo da bolsa e ramo aferente estavam cheios de fe- zes líquidas de cor marrom. A

    Restorative proctocolectomy and ileal pouch (IP) has become an established surgery for patients with chronic ulcerative colitis and poliposis syndromes. The authors report the results of 8-year experience of restorative proctocolectomy and IP. Chart review was performed for 51 patients undergoing IP from 1994 through 2002. Preoperative histopathologic diagnoses were ulcerative colitis (n=39), poliposis syndromes (n=10), 2 Crohn diseases and 1 patient with colorectal cancer and extended resection. Information was obtained regarding patient demographics, type and duration of diseases, previous operations, and indications for surgery. Early (within 30 days after surgery) and late complications were noted. Follow-up included an annual function, physical examination, and biopsies of the pouch and anal transitional zone when were indicated. Of the 51 patients (24 women) with mean follow-up time of 44,5 months (range 12 -108 months), histopathologic diagnoses of ulcerative colitis were changed for Crohn's disease in 2 patients. The overall mortality rate was 2% (1 patient) one death was related to perineal sepsis 45 months after ileal pouch. The overall morbidity rate was 65% (73 complications in 33 patients; early 39%; late 49%) the mean hospitalary stance was 8, 9 days (range 6-25 days). Small bowel obstruction, septic complication and reoperation rates were 36%, 22% and 26%, respectively. The most frequent late complication was pouchitis (31,8%). The ileal pouch was removed in 1 patient, and it is functional in 50 (98%). There was a satisfactory index with 82% with excellent-good results, and 16% and 2% with regular and bad results. Restorative proctocolectomy with an IP is a safe procedure, with low mortality and major morbidity rates. Although total morbidity rate is appreciable, functional results generally are good and patient satisfaction is acceptable

    Resectional procedures for advanced and complicated appendicitis are performed infrequently. Their extent can vary: cecal resection, ileocecectomy, and even right hemicolectomy. We present a very rare case of appendectomy that was combined with partial ileal resection for severe necrotic changes and small perforation of the ileum. A 19-year-old female patient was hospitalized with right iliac fossa pain and fever 10 days after the onset of symptoms. On laparoscopy, a large mass in a right iliac fossa was found. The ultrasound-guided drainage of the suspected appendiceal abscess was unavailable. After conversion using McBurney's incision, acute perforated appendicitis was diagnosed. It was characterized by extension of severe necrotic changes onto the ileal wall and complicated by right iliac fossa abscess. A mass was bluntly divided, and a large amount of pus with fecaliths was discharged and evacuated. Removal of necrotic tissues from the ileal wall led to the appearance of a small defect in the bowel. A standard closure of this defect was considered as very unsafe due to a high risk of suture leakage or bowel stenosis. We perform a resection of the involved ileum combined with appendectomy and drainage/tamponade of an abscess cavity. Postoperative recovery was uneventful. The patient was discharged on the 15th day. In advanced appendicitis, the involved bowel resection can prevent possible complications (e.g., ileus, intestinal fistula, peritonitis, and intra-abdominal abscess). Our case may be the first report of an appendectomy combined with an ileal resection for advanced and complicated appendicitis.

    To find out the significance of the Perforation-Operation Interval (POI) with respect to an early prognosis, in patients with peritonitis which is caused by peptic ulcer perforation. Case series. Place and Duration of the Study: Department of General Surgery, Konaseema Institute of Medical Sciences and RF Amalapuram, Andhra Pradesh, India from 2008-2011. This study included 150 patients with generalized peritonitis, who were diagnosed to have Perforated Peptic Ulcers (PPUs). The diagnosis of the PPUs was established on the basis of the history , the clinical examination and the radiological findings. The perforation-operation interval was calculated from the time of onset of the symptoms like severe abdominal pain or vomiting till the time the patient was operated. Out of the 150 patients 134 were males and 16 were females, with a male : female ratio of 9:1. Their ages ranged between 25-70 years. Out of the 150 patients, 65 patients (43.3%) presented within 24 hours of the onset of severe abdominal pain (Group A), 27 patients (18%) presented between 24-48 hours of the onset of severe abdominal pain (Group B) and 58 patients (38.6%) presented after 48 hours. There was no mortality in Group A and the morbidity was more in Group B and Group C. There were 15 deaths in Group C. The problem of peptic ulcer perforation with its complication, can be decreased by decreasing the perforation -operation time interval, which as per our study, appeared to be the single most important mortality and morbidity indicator in peptic ulcer perforation.

Full thickness soft tissue defects, up to 12 cm in length and up to 8 cm in width. Sufficient vascularization of the foot required, in osteomyelitis, and when joints, fractures, implants and tendons are exposed and when a split skin graft, a local flap, a suralis perforator flap or a free flap is not indicated. For patients, in whom a 1-2 h operation is not possible; necessity of angioplasty; decollement or scars around the distal perforators of the posterior tibial artery; local infection or necrosis of soft tissues and/or bone, which cannot be totally excised. Radical debridement; flap dissection without tourniquet; microdissection; design of the flap on the skin: pivot point ~ 10 cm (6-14 cm) proximal of the tip of the medial malleolus; base ~ 5 cm in width, between the course of the saphenous nerve and of the great saphenous vein and the Achilles tendon; adipofascial pedicle up to 15 cm in length sited over the septum between soleus and flexor digitorum muscles, following the course of the saphenous nerve, with a central skin stripe, which expands into a proximal skin island; skin island is outlined similar to the defect, but larger by 1 to 2 cm, surrounded by an adipofascial border: adjustment of the planning as well as of the elevation of these flaps according to the individual position and the caliber of perforators requires in each case the search for a perforator at the estimated pivot point. Delay of transposition, if the division of more than one perforator proximal to the pivot point obviously diminishes circulation. No "tunnelling "of the pedicle; defects of skin due to the elevation of the flap are replaced by split and meshed skin grafts or temporary

    As the use of compressed air in industrial work has increased, so has the risk of associated pneumatic injury from its improper use. However, damage of large intestine caused by compressed air is uncommon. Herein a case of pneumatic rupture of the rectum is described. The patient was admitted to the Emergency Room complaining of abdominal pain and distension. His colleague triggered a compressed air nozzle over his buttock. On arrival, vital signs were stable but physical examination revealed peritoneal irritation and marked distension of the abdomen. Computed tomography showed a large volume of air in the peritoneal cavity and subcutaneous emphysema at the perineum. A rectal perforation was found at laparotomy and the Hartmann procedure was performed.

    Perforation of the duodenum is an uncommon, but serious complication which may occur in children with dermatomyositis. In this disease vasculitis may involve the bowel to a variable extent and result in radiologic manifestations of intestinal injury ranging from benign pneumatosis intestinalis to signs of bowel perforation. We report two children with dermatomyositis in whom perforation of the second portion of the duodenum occurred. This serious complication should be considered in any child with dermatomyositis when extraluminal gas is suspected on abdominal radiographs.

    Full Text Available A 24-year-old male presented after being involved in a motorcycle accident and was found to have soft tissue defects of the knee with exposure of patella. Due to the severe injury from the popliteal fossa to the posterior aspects of the lower leg, repair with a free flap from anterolateral thigh perforator was planned instead of local calf muscle flap. Preoperative angiography was performed, and it showed that superior medial genicular perforator was patent compared with unreliable filling of the superior lateral genicular perforator. The soft tissue defect was repaired using the superior medial genicular perforator as the recipient vessel. This was performed by creating perforator to perforator anastomosis (supermicrosurgery. The flap survived successfully, and the patient was able to ambulate in a few weeks without serious complications. This case indicates that superior medial genicular perforator can be used as the recipient vessel for covering the soft tissue defects of the knee caused by blunt injury.

    The standard treatment of persistent eardrum perforation is conventional surgical closure using myringoplasty or a tympanoplasty type I. In this study the valence of a modified, CO(2)-laser-assisted de-epithelialization of perforation margins was investigated. A total of 44 patients with mesotympanal eardrum perforation (diameter 1-5 mm) were included in a partially retrospective and partially prospective study. The genesis of the eardrum perforations was partially traumatic or the eardrum did not heal after spontaneous perforation caused by an acute otitis media or after surgery. The procedure was performed under topical anaesthesia. Focussed, adjacent, single CO(2) laser pulses (1 watt, 0.05 s) were applied with the laser otoscope Otoscan (Lumenis, Yokneam, Israel) along the edge of the perforation until complete de-epithelialization. This was done to stimulate growth. Closure of eardrum perforation was monitored using an ear microscope and if this treatment was not successful after three attempts conventional surgical therapy was suggested. Complete eardrum closure occurred in 27 cases (61%), 17 patients (39%) had a residual perforation, of which 9 experienced a significant reduction of the perforation. There were no complications during and after the treatment. A closure rate of at least 61% (27/44) can be expected with a CO(2)-laser-assisted de-epithelialization of the perforation margins. This procedure can be performed under topical anaesthesia and is an economic, painless and facile alternative to conventional surgical treatment.

  9. Perforated Giant Meckel Diverticulitis in an elderly patient: Case report and review of the literature

    Directory of Open Access Journals (Sweden)

    Ryan J. Malcom

    Full Text Available Introduction: Giant Meckel’s diverticula are a relatively rare form of Meckel’s, and henceforth their natural history is not clearly defined. They’re currently thought of as an infrequent form of ileal dysgenesis. Noted complications include perforation, torsion and bowel obstruction. A much rarer presentation is Giant Meckel’s diverticulitis. Case: A 71 year old white female presented herself to the Emergency Department of a small urban community hospital, complaining of severe abdominal pain, nausea & vomiting. Her preoperative workup was consistent with Giant Meckel’s diverticulitis, with evidence for perforation. She was taken for a laparotomy, which confirmed the diagnosis, and was treated with a small bowel resection. She made an otherwise uncomplicated recovery. Conclusion: Giant Meckel’s diverticula and their complications require a high index of suspicion and once diagnosed, they should be managed expeditiously to avoid complications.

    Gallstone ileus is an uncommon type of mechanical intestinal obstruction caused by an intraluminal gallstone, and preoperative diagnosis is difficult in the Emergency department. This study is a retrospective analysis of the clinical presentation of 5 patients with gallstone ileus treated between 2000-2010. Clinical features, diagnostic testing, and surgical treatment were analyzed. Five patients were included: 2 cases showed bowel obstruction; 2 patients presented a recurrent gallstone ileus with prior surgical intervention; and one patient presented acute peritonitis due to perforation of an ileal diverticula. In all cases CT confirmed the preoperative diagnosis. In our experience, gallstone ileus may present with clinical features other than intestinal obstruction. In suspicious cases CT may be useful to decrease diagnostic delay, which is associated with more complications. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

  11. An unusual case of giant ileal diverticulum–A case report

    Directory of Open Access Journals (Sweden)

    Fang Ju Koh

    Full Text Available Small bowel diverticulosis is rare with an incidence of 1–2% in the general population. It is an uncommon cause of gastrointestinal bleeding that ranges from obscure to overt bleeding. Large ileal diverticula are extremely rare and bleeding complications can result in high overall mortality.A young gentleman presented with persistent per-rectal bleeding and drop in hemoglobin level. He was recently diagnosed with acute myeloid leukemia and was undergoing chemotherapy. A computed tomography scan of the abdomen and pelvis revealed a giant ileal diverticulum. In view of on-going bleeding, he underwent double balloon enteroscopy which revealed active bleeding from an ulcer within the giant ileal diverticulum and successful hemostasis was performed with hemostatic clips.Small bowel diverticulosis though uncommon has to be considered during workup for gastrointestinal bleeding. Endoscopic treatment is a modern approach towards small bowel diverticular bleeding that is effective and less invasive.

    Full Text Available Aim. Single-access laparoscopic surgery (SALS can be effective for benign and malignant diseases of the ileum in both the elective and urgent setting. Methods. Ten consecutive, nonselected patients with ileal disease requiring surgery over a twelve month period were included. All had a preoperative abdominopelvic computerized tomogram. Peritoneal access was achieved via a single transumbilical incision and a “surgical glove port” utilized as our preferred access device. With the pneumoperitoneum established, the relevant ileal loop was located using standard rigid instruments. For ileal resection, anastomosis, or enterotomy, the site of pathology was delivered and addressed extracorporeally. Result. The median (range age of the patients was 42.5 (22–78 years, and the median body mass index was 22 (20.2–28 kg/m2. Procedures included tru-cut biopsy of an ileal mesenteric mass, loop ileostomy and ileotomy for impacted gallstone extraction as well as ileal (=3 and ileocaecal resection (=4. Mean (range incision length was 2.5 (2–5 cm. All convalescences were uncomplicated. Conclusions. These preliminary results show that SALS is an efficient and safe modality for the surgical management of ileal disease with all the advantages of minimal access surgery and without requiring a significant increase in theatre resource or cost or incurring extra patient morbidity.

    Two experiments were conducted to determine the effect of neutral detergent fiber (NDF) on endogenous amino acids and protein ileal losses; and also apparent ileal digestibility (AID), and standardized ileal digestibility (SID) of amino acids and crude protein. Sixteen barrows were fed four protein-free diets containing graded NDF levels in Experiment 1. NDF was a mixture of sugarcane bagasse and corn leaves (SBCL). Twenty-four barrows were fed diets with soybean protein concentrate (SPC) or casein as protein sources and SBCL or corncobs (CC) as NDF sources in Experiment 2. In Experiment 1, a linear increase (P protein ileal losses was observed with increased NDF levels, except for arginine, histidine, methionine and proline. In Experiment 2, protein (P Protein and NDF sources significantly affected (P protein, which was higher in casein diets (92.8%) and CC diets (92.7%). NDF source had no effect (P > 0.05) on SID of amino acids. Overall, this study showed that NDF increased endogenous amino acid and protein ileal losses, but did not affect ileal digestibility of amino acids. © 2016 Japanese Society of Animal Science.

    2010-06-01

    Full Text Available Abstract Introduction Jejunal diverticula are rare and are usually asymptomatic. However, they may cause chronic non-specific symptoms or rarely lead to an acute presentation. Case presentation We report the case of an 82-year-old Caucasian woman presenting with a one-day history of generalized abdominal pain, with three episodes of vomiting. An abdominal X-ray displayed multiple dilated loops of the small bowel. A subsequent computed tomography scan of the abdomen and pelvis revealed a thickening of the duodenum and dilatation of the proximal jejunum. Multiple small bowel diverticula were identified with surrounding pockets of free air adjacent to the jejunal diverticula suggestive of a small bowel perforation. Our patient underwent a laparotomy, which identified multiple jejunal diverticula with two pinhole jejunal perforations and associated fecal contamination. The perforations were repaired with primary closure and extensive washout was performed. Conclusion Jejunal diverticulosis in the elderly can lead to significant morbidity and mortality and so should be suspected in those presenting with crampy abdominal pain and altered bowel habits.

  17. Evidence for validity of ileal digestibility coefficients in monogastrics.

    Science.gov (United States)

    Columbus, Daniel; de Lange, Cornelis F M

    2012-08-01

    Measures of amino acid (AA) digestibility are used widely to estimate bioavailability of AA in feed and food ingredients for monogastric animals. In principle, the digestibility assay is simpler than in vivo assessments of AA bioavailability and allows for simultaneous estimation of the bioavailability of all AA in an experimental diet. It is generally assumed that absorption of intact AA in the hindgut of monogastrics is minimal, even though colonocytes do contain AA transporters and have been shown to absorb AA. This assumption is supported by the observation that infusion of AA into the hindgut does not improve nitrogen balance in monogastrics. In addition, growth performance of monogastrics is more highly correlated with ileal than faecal AA digestibility. Therefore, ileal digestibility coefficients provide better estimates of AA bioavailability than faecal digestibility coefficients. Measures of apparent ileal digestibility (AID) of AA are confounded with endogenous gut AA losses (EAAL). The curvilinear increase in AID of AA with increasing dietary AA level has been attributed to the relatively large contribution of EAAL to total ileal AA flows at low dietary AA levels. Subtracting basal EAAL from total ileal AA flows yields standardized ileal digestibility (SID) coefficients that appear to be more additive than AID coefficients in mixtures of feed ingredients. An implicit assumption when using SID AA coefficients in diet formulation is that the post-absorptive utilization of AA is not influenced by the dietary protein source. This assumption appears inappropriate when using feed or food ingredients that have been over-heated, induce large amounts of EAAL, or contain substantial amounts of fermentable fibre. Improved understanding of processes that contribute to the discrepancy between bioavailability and ileal digestibility will allow a more effective use of AA digestibility coefficients in diet formulation.

    In order to assess ileal dysfunction in patients with complaints after pelvic radiation therapy, retention measurements and scintigraphic imaging with selenium 75 homocholic acid conjugated with taurine ( 75 Se-HCAT), combined with the carbon 14 clycochol breath test, were evaluated in 39 patients. In 22 patients without ileal resection the results of the 75 Se-HCAT test and the breath test differentiated between a normal functioning ileum (both tests negative) and ileal dysfunction as a cause of complaints (one or both tests positive). Among the patients with ileal dysfunction, the combination of both tests permitted those with bacterial overgrowth (breath test positive, 75 Se-HCAT negative) to be separated from patients with evidence of bile acid malabsorption ( 75 Se-HCAT positive, breath test positive or negative). In 17 patients with small-bowel resection, the 75 Se-HCAT test helped to estimate the severity of bile acid malabsorption with implications for therapy. In this group the breath test was false-negative in 7 cases with abnormal 75 Se-HCAT. Additional systematically performed scintigraphic imaging improved the accuracy of the 75 Se-HCAT test, revealing cases with prolonged colonic accumulation of the radiopharmaceutical, causing spurious retention values. In conclusion, assessment of ileal dysfunction by nuclear medicine techniques in post-irradiation conditions provides information about the aetiology and therefore the possibility of adjustment in the clinical management.

    Alobid, Isam

    2017-05-26

    The management of septal perforations is a challenge for the surgeon. A wide variety of surgical techniques have been described, with different approaches. There is no scientific evidence to support a particular approach. The objective of this review is to present a practical guide on the technique of choice for each case of septal perforation. Inspection of the nasal mucosa, the size of the perforation, the location and especially the osteo-cartilaginous support, are the pillars of a successful surgery. For the sliding or rotating flaps of the mucosa of the septum it is essential to know in advance if the elevation of the mucopericondrio or mucoperiosteo of the septum is possible, otherwise the use of these flaps would not be indicated. The flaps of the lateral wall or nasal floor are the alternative. The pericranial flap may be indicated in total or near total perforations. The remnant of the nasal septum and status of osteo-cartilaginous support are the determining factors in the management of septal perforations. Each case should be evaluated individually and the approach chosen according to the size and location of the perforation, mucosal quality, personal history, previous surgery and the experience of the surgeon.

    Rush, Sloan W.

    2016-01-01

    Purpose. To compare the long-term outcomes of infectious versus sterile perforated corneal ulcers after therapeutic penetrating keratoplasty in the United States. Methods. The charts of 45 consecutive eyes that underwent primary therapeutic penetrating keratoplasty for a perforated corneal ulcer at a single center were retrospectively reviewed. The perforated ulcers were classified as infectious or sterile and the underlying demographics, clinical features, and 36-month outcomes were compared among the two groups. Results. Mean follow-up among subjects was 38.6 (±6.9) months. Patients presenting with sterile perforated ulcers were more likely to have a peripheral perforation location (p = 0.0333) and recurrence of the underlying disease condition (p = 0.0321), require adjunctive surgical measures in the immediate postoperative period (p ulcer group. Conclusions. Sterile perforated corneal ulcers have a worse prognosis and may be more frequent than those caused by infectious disease in the United States compared to the developing world.

    Full Text Available Myocardial perforation is a rare complication of permanent pacemaker implantation. While most of the perforations occur at the time of implantation or within the first 24 h, delayed myocardial perforations are very rare. The clinical course is extremely variable with some patients presenting completely asymptomatic, while others can develop cardiac tamponade and haemodynamic instability. We report an unusual case of a subacute ventricular perforation caused by a passive-fixation lead two weeks after implantation and we successfully managed to extract the lead under local anaesthesia, without the patient undergoing surgery, as recommended in the previously published reports.

  2. CORRELATION BETWEEN TYMPANIC MEMBRANE PERFORATION AND HEARING LOSS

    2016-04-01

    Full Text Available Introduction: Perforation of the tympanic membrane primarily results from middle ear infections, trauma or iatrogenic causes. The perforation causes conductive hearing loss by reducing the surface area available for sound transmission to the ossicular chain. Objective: The objective was to analyze the characteristics of tympanic membrane perforations in relation to hearing loss and to determine the type and degree of hearing loss. Materials and methods: We analyzed audiometric, otoscopic findings and medical reports of 218 patients, 114 males (52.3% and 104 females (47.7%, aged 9 to 75 years (mean age of 47.9 years, examined during the period of November 2012 to October 2015. For statistical data analysis we used Chi-square test with level of significance p<0.05. Results: Most of the patients had unilateral perforations (89% with right ear predominance and involvement of two quadrants of pars tensa (37.2%. Mean air-bone gap was 23.9 dB. The largest air-bone gap was at frequency of 250 Hz. Most of the patients (73.1% had mixed hearing loss (p=0.032, and average hearing thresholds from 21 to 40 dB. Conclusion: Mean air-bone gap is largest at the lower frequencies, and decreases as frequency increases. Size of the perforation has effect on hearing loss. Mean air-bone gap increases with increasing size of the perforation. There is no big difference between the mean air-bone gap in posterior versus anterior perforations.

    Full Text Available History of present illness: A 53-year-old male with a history of daily alcohol abuse presented with sudden onset epigastric pain. The pain radiated to the right upper abdominal quadrant and was associated with shortness of breath and nausea. The patient’s vitals were notable for blood pressure of 181/107 and a heart rate of 124. He was in moderate distress and had a firm, distended abdomen with diffuse tenderness to palpation, without rebound or guarding. Significant findings: In the chest radiograph, there was obvious free air under the both the right diaphragm (above the liver and the left diaphragm, consistent with pneumoperitoneum. Discussion: A perforated ulcer is a surgical emergency. Overall mortality has been shown to be approximately 6.2%.1 Rapid diagnosis is essential as prognosis improves if treatment is initiated within the first six hours and worsens after 12 hours.2 The sensitivity for detecting pneumoperitoneum on plain radiography ranges from 50%-80%3-8 with specificity of 53%.7 An upright chest radiograph can detect as little as one to two milliliters of air.9,10 If free air is not seen on a posteroanterior (PA upright chest radiograph, an upright lateral chest radiograph can be obtained, which is more sensitive (98% sensitivity.8,11 About 10%-20% of ruptured ulcers will not present with visible free-air under the diaphragm on plain x-ray.12 In this case, given the free air seen on chest radiograph and peritoneal signs on exam, the patient was taken straight to the operating room for general surgery.

    The (poly)phenols in ileal fluid after ingestion of raspberries were analyzed by targeted and nontargeted LC-MS(n) approaches. Targeted approaches identified major anthocyanin and ellagitannin components at varying recoveries and with considerable interindividual variation. Nontargeted LC-MS(n) analysis using an orbitrap mass spectrometer gave exact mass MS data which were sifted using a software program to select peaks that changed significantly after supplementation. This method confirmed the recovery of the targeted components but also identified novel raspberry-specific metabolites. Some components (including ellagitannin and previously unidentified proanthocyanidin derivatives) may have arisen from raspberry seeds that survived intact in ileal samples. Other components include potential breakdown products of anthocyanins, unidentified components, and phenolic metabolites formed either in the gut epithelia or after absorption into the circulatory system and efflux back into the gut lumen. The possible physiological roles of the ileal metabolites in the large bowel are discussed.

    The use of laparoscopy has been established in improving perioperative and postoperative outcomes for patients with simple appendicitis. Laparoscopic appendectomy is associated with less wound pain, less wound infection, a shorter hospital stay, and faster overall recovery when compared to the open appendectomy for uncomplicated cases. In the past two decades, the use of laparoscopy for the treatment of perforated appendicitis to take the advantages of minimally invasiveness has increased. This article reviewed the prevalence, approaches, safety disclaimers, perioperative and postoperative outcomes of the laparoscopic appendectomy in the treatment of patients with perforated appendicitis. Special issues including the conversion, interval appendectomy, laparoscopic approach for elderly or obese patient are also discussed to define the role of laparoscopic treatment for patients with perforated appendicitis.

    2013-11-01

    Full Text Available BackgroundPartially resecting ribs of the recipient site to facilitate easy anastomosis of the internal mammary vessels to free flaps during breast reconstruction can cause chest wall pain or deformities. To avoid this, the intercostal perforating branches of the internal mammary vessels can be used for anastomosis. The purpose of this study was to investigate the location and size of the internal mammary perforator vessels based on clinical intraoperative findings and to determine their reliability as recipient vessels for breast reconstruction with microsurgical free tissue transfer.MethodsTwelve patients were preoperatively screened for the presence of internal mammary perforators using Doppler tracing. After modified radical mastectomy was performed by a general surgeon, the location and size of the internal mammary perforator vessels were microscopically investigated. The external diameter was examined using a vessel-measuring gauge from a mechanical coupling device, and the distance from the mid-sternal line to the perforator was also measured.ResultsThe largest arterial perforator averaged 1.5 mm, and the largest venous perforator averaged 2.2 mm. Perforators emerging from the second intercostal space had the largest average external diameter; the second intercostal space also had the largest number of perforators arising from it. The average distance from the mid-sternal line to the perforator was 20.2 mm.ConclusionsInternal mammary perforators presented consistent and reliable anatomy in this study. Based on these results, the internal mammary perforators appear to have a suitable diameter for microvascular anastomosis and should be considered as an alternative recipient vessel to the internal mammary vessel.

  7. Avoiding denervation of rectus abdominis in DIEP flap harvest: the importance of medial row perforators.

    2008-09-01

    The deep inferior epigastric artery (DIEA) perforator flap for breast reconstruction spares rectus abdominis muscle and has low donor-site morbidity. However, abdominal wall weakness and bulge remain significant complications, with damage to the motor innervation of the rectus abdominis postulated as a cause. This study describes the relationship between the nerves supplying rectus abdominis and perforators, based on a thorough cadaveric study and review of the literature. Twenty hemiabdominal walls from fresh and embalmed cadavers were dissected, mapping the course of the nerve and vascular supply of rectus abdominis. The infraumbilical segment of rectus abdominis was innervated by T9-L1, with four to seven nerve branches entering rectus abdominis from its lateral border (12 cases) or posterior surface (93 cases). Each nerve entered a nerve plexus running with the most lateral branch of the DIEA, before running with arterial perforators into rectus abdominis. Nerves entered rectus muscle more medial than the lateral row perforators (83 percent of cases), with the medial branches of the DIEA devoid of these nerve branches. The nerves innervating rectus abdominis are at risk during the raising of a DIEA perforator flap. These nerves enter the posterior surface of rectus abdominis and run with the most lateral branch of the DIEA and its perforators. Damage to these nerves may denervate rectus abdominis muscle and contribute to donor-site morbidity. As medial row perforators were not related to these motor nerves, these perforators are ideal for inclusion in DIEA perforator and transverse rectus abdominis myocutaneous flaps.

  9. Perforation in a patient with stercoral colitis and diverticulosis: who did it?

    Directory of Open Access Journals (Sweden)

    Vijaya R. Bhatt

    2014-02-01

    Full Text Available Stercoral colitis with perforation of the colon is an uncommon, yet life-threatening cause of the acute abdomen. No one defining symptom exists for stercoral colitis; it may present asymptomatically or with vague symptoms. Diagnostic delay may result in perforation of the colon resulting in complications, even death. Moreover, stercoral perforation of the colon can also present with localized left lower quadrant abdominal pain masquerading as diverticulitis. Diverticular diseases and stercoral colitis share similar pathophysiology; furthermore, they may coexist, further complicating the diagnostic dilemma. The ability to decide the cause of perforation in a patient with both stercoral colitis and diverticulosis has not been discussed. We, therefore, report this case of stercoral perforation in a patient with diverticulosis and include a discussion of the epidemiology, clinical presentation, and a review of helpful diagnostic clues for a rapid differentiation to allow for accurate diagnosis and treatment.

    Full Text Available Objective To compare the erectile function (EF and sexual desire (SD in men after radical cystoprostatectomy (RCP who had either an ileal conduit urinary diversion or orthotropic ileal neobladder substitution. Materials and Methods Eighty one sexually active men with bladder cancer were enrolled in this prospective study. After RCP according to patients' preferences they underwent either ileal conduit urinary diversion (n = 41 or orthotropic ileal neobladder substitution (n = 40. EF and SD were assessed using International Index of Erectile Function (IIEF questionnaire. Patients were assessed at 4-week before surgery and were followed up at 1, 6, and 12-month postoperatively using the same questionnaire. Results Postoperatively the EF and SD domains deteriorated significantly in both groups, but in a small proportion of the patients submitted to ileal neobladder they gradually improved with time (P = 0.006. At 12-month postoperative period, 4 (9.8% and 14 (35.0% patients in ileal conduit and ileal neobladder groups were able to achieve erections hard enough for vaginal penetration and maintained their erection to completion of intercourse, respectively (P = 0.006. Among patients in the ileal conduit and ileal neobladder groups, additional 4 (9.8% and 7 (17.1% patients were able to get some erection, but were unable to maintain their erection to completion of intercourse (P = 0.02. At 12-month follow up period 24.4% of the ileal conduit and 45.0% of the ileal neobladder patients rated their sexual desire very high or high (P = 0.01. Conclusion When performed properly, orthotopic ileal neobladder substitution after RCP offers better long-term results in terms of EF and SD.

    Intact surgical gloves are essential to avoid contact with blood and other body fluids. The objective of this study was to estimate the incidence of glove perforations during interventional radiological procedures. In this study, a total of 758 gloves used in 94 interventional radiological procedures were examined for perforations. Eleven perforations were encountered, only one of which was of occult type. No significant difference in the frequency of glove perforation was found between the categories with varying time duration.

  12. The research progress of acute small bowel perforation

    Directory of Open Access Journals (Sweden)

    Rudolf Schiessel

    2015-08-01

    Full Text Available This article reviews the various aetiologies of small bowel perforations and their management. In addition to the well-known aetiologies such as trauma, inflammation and circulatory disorders, several new causes of small bowel perforation have been described in recent years. The spectrum reaches from iatrogenic perforations during laparoscopic surgery or enteroscopies to drug-induced perforations with new anticancer agents. The management of small bowel perforations requires a concept consisting of the safe revision of the leaking bowel and the treatment of the peritonitis. Depending on the local situation and the condition of the patient, several treatment options are available. The surgical management of the bowel leak can range from a simple primary closure to a delayed restoration of bowel continuity. When the condition of the bowel or patient is frail, the risk of a failure of a closure or anastomosis is too high, and the exteriorization of the bowel defect as a primary measure is a safe option. The treatment of the peritonitis is also dependent on the condition of the patient and the local situation. Early stages of peritonitis can be treated by a simple peritoneal lavage, either performed by laparoscopy or laparotomy. Severe forms of peritonitis with multi-organ failure and an abdominal compartment syndrome need repeated peritoneal revisions. In such cases, the abdomen can only be closed temporarily. Different technical options are available in order to overcome the difficult care of these patients.

    Full Text Available Abstract Background Intestinal tuberculosis is a common problem in endemic areas, causing considerable morbidity and mortality. An isolated primary caecal perforation of tubercular origin is exceptionally uncommon. Case presentation We report the case of a 39 year old male who presented with features of perforation peritonitis, which on laparotomy revealed a caecal perforation with a dusky appendix. A standard right hemicolectomy with ileostomy and peritoneal toileting was done. Histopathology revealed multiple transmural caseating granulomas with Langerhans-type giant cells and acid-fast bacilli, consistent with tuberculosis, present only in the caecum. Conclusions We report this extremely rare presentation of primary caecal tuberculosis to sensitize the medical fraternity to its rare occurrence, which will be of paramount importance owing to the increasing incidence of tuberculosis all over the world, especially among the developing countries.

Between November 2003 and December 2011, a total of 8504 ERCPs were performed at our regional endoscopy center. Sixteen perforations (0.45% were identified and retrospectively reviewed. Results. Nine of these 16 patients with perforations were periampullary, 3 duodenal, 1 gastric fundus, and 3 patients had a perforation of an afferent limb of a Billroth II anastomosis. All patients with perforations were recognized during ERCP by X-ray and managed immediately. One patient with duodenal perforation and three patients with afferent limb perforation received surgery, others received medical conservative treatment which included suturing lesion, endoscopic nasobiliary drainage (ENBD, endoscopic retrograde pancreatic duct drainage (ERPD, gastrointestinal decompression, fasting, broad-spectrum antibiotics, and so on. All patients with perforation recovered successfully. Conclusions. We found that: (1 the diagnosis of perforation during ERCP may be easy, but you must pay attention to it. (2 Most retroperitoneal perforations can recover with only medical conservative treatment in early phase. (3 Most peritoneal perforations need surgery unless you can close the lesion up under endoscopy in early phase.

    The aim of this study was to determine the sleep quality and the association between sleep quality and quality of life in people with ileal conduit. A descriptive and cross-sectional design was adopted. The study sample comprised 111 people with ileal conduit operated on in urology clinics in a state hospital between January 2011 and May 2014. Six months after the operation, they were called by telephone to participate in the study. Data for the study were collected using a questionnaire form, the Pittsburgh Sleep Quality Index (PSQI) and the Stoma Quality of Life Scale (SQLS). The mean ± SD total PSQI score of the people with ileal conduit was 10.20 ± 2.95, mean total score of SQLS was 43.63 ± 7.21, mean Work/Social Function domain score was 37.27 ± 5.80 and mean Stoma Function domain score was 50.0 ± 12.56. The total sleep quality had a low degree of negative correlation with total SQLS score, a medium degree of negative correlation with Work/Social Function (r = -0.327, p  .001). People using a night drainage system had higher sleep quality. This study determined that quality of life and sleep deteriorate in people with ileal conduit. The quality of life decreases when the sleep quality is poor, and decreased quality of life affects quality of sleep in people with ileal conduit.

    The purpose of this study was to examine factors that could help reduce primary perforation during insertion of a framed intrauterine device (IUD) and to determine factors that contribute in generating enough uterine muscle force to cause embedment and secondary perforation of an IUD. The objective was also to evaluate the main underlying mechanism of IUD expulsion. We compared known IUD insertion forces for "framed" devices with known perforation forces in vitro (hysterectomy specimens) and known IUD removal forces and calculated a range of possible intrauterine forces using pressure and surface area. These were compared with known perforation forces. IUD insertion forces range from 1.5 N to 6.5 N. Removal forces range from 1 N to 5.8 N and fracture forces from 8.7 N to 30 N depending upon device. Measured perforation forces are from 20 N to 54 N, and calculations show the uterus is capable of generating up to 50 N of myometrial force depending on internal pressure and surface area. Primary perforation with conventional framed IUDs may occur if the insertion pressure exceeds the perforation resistance of the uterine fundus. This is more likely to occur if the front end of the inserter/IUD is narrow, the passage through the cervix is difficult, and the procedure is complex. IUD embedment and secondary perforation and IUD expulsion may be due to imbalance between the size of the IUD and that of the uterine cavity, causing production of asymmetrical uterine forces. The uterine muscle seems capable of generating enough force to cause an IUD to perforate the myometrium provided it is applied asymmetrically. A physical theory for IUD expulsion and secondary IUD perforation is given.

  5. Three-point bending of honeycomb sandwich beams with facesheet perforations

    A novel square honeycomb-cored sandwich beam with perforated bottom facesheet is investigated under three-point bending, both analytically and numerically. Perforated square holes in the bottom facesheet are characterized by the area ratio of the hole to intact facesheet (perforation ratio). While for large-scale engineering applications like the decks of cargo vehicles and transportation ships, the perforations are needed to facilitate the fabrication process (e.g., laser welding) as well as service maintenance, it is demonstrated that these perforations, when properly designed, can also enhance the resistance of the sandwich to bending. For illustration, fair comparisons among competing sandwich designs having different perforation ratios but equal mass is achieved by systematically thickening the core webs. Further, the perforated sandwich beam is designed with a relatively thick facesheet to avoid local indention failure so that it mainly fails in two competing modes: (1) bending failure, i.e., yielding of beam cross-section and buckling of top facesheet caused by bending moment; (2) shear failure, i.e., yielding and buckling of core webs due to shear forcing. The sensitivity of the failure loads to the ratio of core height to beam span is also discussed for varying perforation ratios. As the perforation ratio is increased, the load of shear failure increases due to thickening core webs, while that of bending failure decreases due to the weakening bottom facesheet. Design of a sandwich beam with optimal perforation ratio is realized when the two failure loads are equal, leading to significantly enhanced failure load (up to 60% increase) relative to that of a non-perforated sandwich beam with equal mass.

    Perforation is an artificial communication between the root canal system and supporting tissues of the teeth. Root perforation complicates the treatment and deprives the prognosis if not properly managed. A wide variety of materials to seal the perforations have been suggested in literature. There are many comparative studies showing the efficacy of one material over the other. Literature shows many reviews on diagnosis, treatment plan and factors affecting prognosis of perforation repair; but none of these articles elaborated upon various materials available to seal the perforation. The present article aims at describing all the materials used for perforation repair from the past till date; it also offers a literature review of all the articles published over last four decades referred to the treatment of perforation with various root repair materials.

    Oral impalement injuries are common in children. We report a case of severe pharyngeal toothbrush perforation in a 15-month-old infant. A 15-month-old child was admitted for a penetrating oral injury caused by a toothbrush. There was no hemorrhagic or neurological complication. A CT scan showed the toothbrush in the right parapharyngeal region with its extremity in the mastoid region. Exploration and extraction of the toothbrush was performed under general anesthesia. The outcome was uneventful. Penetrating oral cavity wounds caused by a toothbrush in children may be severe and must be explored in the operating room. A preoperative CT scan must be performed to complete the assessment of lesions. The risk of infection is high and an antibiotic prophylaxis is recommended. Neurological and vascular complications may occur but they are rare. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

  8. Spontaneous Perforation of Pyometra: A Case Report

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Pyometra is the accumulation of purulent material in the uterine cavity. Its reported incidence is 0.01–0.5% in gynecologic patients; however, as far as elderly patients are concerned, its incidence is 13.6% [3]. The most common cause of pyometra is malignant diseases of genital tract and the consequences of their treatment (radiotherapy. Other causes are benign tumors like leiomyoma, endometrial polyps, senile cervicitis, cervical occlusion after surgery, puerperal infections, and congenital cervical anomalies. Spontaneous rupture of the uterus is an extremely rare complication of pyometra. To our knowledge, only 21 cases of spontaneous perforation of pyometra have been reported in English literature since 1980. This paper reports an additional case of spontaneous uterine rupture.

    Primary gastrointestinal perforations have an incidence of between 1% and 3% in NICU patients. The 3 Centers participating in this study cover nearly 40% of the NICU population of the Lazio Region--Italy. The aim of this study is to discuss factors affecting survival in patients affected by a primary intestinal perforation. From 1991 to 2001, 67 cases of 85 with a neonatal gastrointestinal perforation, were related to primary bowel lesions. Necrotizing enterocolitis (NEC) was not always the cause of perforation and in many patients an isolated bowel lesion without signs of NEC was found. The aim of this study was to examine clinical and intraoperative findings of NEC and non NEC perforations and their impact on survival. A relevant number of these patients were extremely low-birth weight (ELBW). Controversies about treatment of this category of neonates are discussed. Patients were 37 males and 30 females (mean birth weight 1 274.8 g, mean gestational age 28.9 weeks, mean age at perforation 10 days). Overall survival was 56.8%. Patients were divided by intraoperative findings in 2 groups: NEC (n=48), or isolated intestinal perforation (IIP) without signs of NEC (n=19). Differences between these 2 groups with regard to birth weight, maturity, associated cardiac anomalies (patent ductus arteriosus, PDA) were significant. NEC and IIP behaved as 2 distinct entities, each with peculiar clinical (age at perforation, oral feeding, need of ventilatory support) and radiological aspects. At surgery, multiple lesion on necrotic bowel were typical of NEC versus single, isolated perforations on healthy bowel typical of IIP. Overall survival was almost identical in the 2 groups (59% vs 58%). ELBW patients (55% of the total neonatal intestinal perforations) were also studied. There were 21 patients with NEC and 16 with IIP. The 2 groups were different in age at perforation, previous oral feeding and associated cardiac anomalies (PDA). Overall survival was 62% for NEC and 50% for

    2011-01-01

    Full Text Available Ciona intestinalis and Styela clava, two nuisance species for Prince Edward Island’s blue mussel industry, were treated with individual perforations using nails or hypodermic needles. Other treatments using the same species included simultaneous perforations using perforation devices with low, medium and high needle density, either with or without vinegar injections. Mortality levels estimated for all ranges of individual perforations were significantly higher than mortality levels estimated in control groups during treatments conducted at laboratory facilities. Mortality of C. intestinalis reached 100% for 60 individual perforations or injection of 0.05 mL of vinegar. In S. clava, 100 individual perforations resulted in 100% mortality. Two applications of the high-density perforation device resulted in 80% mortality of C. intestinalis. During field testing, two applications of the same high-density needle device did not significantly decrease C. intestinalis wet weight, regardless of the addition of vinegar. The field applicability of perforation upon tunicates fouling mussel socks was at least in part limited by the uneven surface created by the mussels and the possible inhibition of bacterial growth caused by low water temperatures. Perforation and vinegar injection showed to be successful in laboratory trials and should be further studied with different perforation devices under field conditions.

    Full Text Available Background: A total of 27 patients of perforated duodenal ulcer admitted in our institution between December 2010 and November 2012 were treated and studied. Materials and Methods: All patients were diagnosed on the basis of clinical and radiological findings, exploratory laparotomy was performed and simple closure of perforation with placement of Graham′s omental patch was carried out. This was followed by triple regimen for Helicobacter pylori eradication. Results: All patients were male, maximum incidence (61.54% was noted in the age group of 21-30, ′O′ +ve blood group was most commonly observed in our patients. Eight patients had history suggestive of acute acid peptic disease. Mean time interval between the start of symptoms and surgery was 43 h. No morbidity except minimal pleural effusion was seen in one case. There was no mortality in our series. Conclusion: We conclude that although a number of definitive surgeries have been described for acid peptic disease, but the requirement of such procedures has come down due to increasing use of H. pylori eradication therapy and proton pump inhibitors. However, surgery for complications especially for duodenal ulcer perforation has not reduced concomitantly. Incidence is greater in young males.

    Background: To assess the value of computed tomography (CT) in patients with acute perforated sigmoid diverticulitis in correlation with the Hinchey classification of perforated diverticular disease. Methods: Thirty patients with acute perforated sigmoid diverticulitis underwent computed tomography prior to surgery. Computed tomography scans were compared with the surgical and histopathological reports, utilizing the Hinchey classification. Results: In 28 of the 30 (93%) patients examined, the Hinchey stage was correctly determined by means of computed tomography. One patient with Hinchey stage IV was falsely classified as Hinchey stage III, and one patient with Hinchey stage III as Hinchey stage II. Computed tomography revealed 12 out of 14 (86%) patients with perforation sites and 3 out of 3 (100%) patients with contained perforation. In one of 17 (6%) patients with surgically or histopathologically proven perforation or contained perforation, a bowel wall discontinuity was revealed by computed tomography. In 6 of the 17 (35%) patients with surgical or histopathological perforation or contained perforation, extraluminal contrast material was detected by computed tomography. Conclusions: Computed tomography is a valuable imaging tool for determining the degree of acute perforated sigmoid diverticulitis, by means of which patients can be stratified according to the severity of the disease; furthermore, this tool is of assistance in surgical planning

    2006-11-01

    A combined septal perforation repair and rhinoplasty was performed in 80 patients presenting with septal perforations (size 1 to 5 cm) and external nasal deformities. The external rhinoplasty approach was used for all cases and the perforation was repaired using bilateral intranasal mucosal advancement flaps with a connective tissue interposition graft in between. Complete closure of the perforation was achieved in 90% of perforations of size up to 3.5 cm and in only 70% of perforations that were larger than 3.5 cm. Cosmetically, 95% were very satisfied with their aesthetic result. The external rhinoplasty approach proved to be very helpful in the process of septal perforation repair especially in large and posteriorly located perforations and in cases where the caudal septal cartilage was previously resected. Our results show that septal perforation repair can be safely combined with rhinoplasty and that some of the routine rhinoplasty maneuvers, such as medial osteotomies and dorsal lowering, could even facilitate the process of septal perforation repair.

    Full Text Available High prevalence and insufficient efficacy of medical treatment in type 2 diabetes mellitus (T2DM poses a major challenge for medical care. Generally, only 30% of patients reach therapeutic goals, while remission occurs only in the minority of patients. In the obese (BMI>35 kg/m2, bariatric surgery provides an alternative to pharmacological treatment of T2DM, boosting remission/compensation rate up to 76.8%. A few recent clinical studies explored the anti-diabetic effect of ileal transposition (IT. This type of surgery targets restoration of incretin balance by proximal transposition of ileal segment. In this review, we discuss the salutary mechanisms of IT in T2DM based on the analysis of the pioneering clinical trials.

    Endovenous closure of incompetent saphenous veins has been reported to facilitate venous ulcer healing; however, there is little information about the effectiveness of perforator ablation (PA) in healing recalcitrant venous ulcers. We report our experience with PA with venous ulcers unresponsive to prolonged compression therapy. Patients with nonhealing venous ulcers of >3 months' duration underwent duplex ultrasound to assess their lower extremity venous system for incompetence of superficial, perforating, and deep veins. Patients who had either no saphenous incompetence or persistent ulcers after saphenous ablation underwent PA of incompetent perforating veins >3 mm that demonstrated reflux; initial treatment was performed on the perforator vein adjacent to the ulcer with additional incompetent veins treated if ulcer healing failed. Seventy-five ulcers with 86 associated incompetent perforating veins were treated with PA in 45 patients with CEAP 6 recalcitrant venous ulcers. Treated incompetent perforator veins were located in the medial ankle (61%), calf (37%), and lateral ankle (2%). Initial success of PA, assessed by postprocedure duplex ultrasound, was 58%; repeat ablation was 90% successful and 71% had eventual successful perforator closure. No complications (skin necrosis, infection, or nerve injury) occurred. Failure of ulcer healing with successful perforator closure occurred in 10% and was due to intercurrent illness, patient noncompliance, and patient death due to unrelated causes. Of patients who healed their ulcers, the healing occurred at a mean of 138 days; an average PA of 1.5 incompetent veins per ulcer was required for healing. Ninety percent of ulcers healed when at least one perforator was closed; no ulcer healed without at least one perforator being closed.

    Despite modern therapeutical options,perforated sigma diverticulitis still represents a life-threatening disease. In terms of diagnostic and therapeutic proceeding, the covered perforation has to be distinguished from free perforation.Primary therapeutic objective is the excision of the inflamed bowel segment to avoid abdominal sepsis.Therapeutic options for covered perforation include conservative treatment with or without placement of interventional drains. A free perforated diverticulitis implies the resection of the perforated bowel segment. Primary anastomosis should be aspired. In advanced cases, Hartmann procedure may be required. Individual decision making should be based on individual risk profile, on peritonitis severity score and on surgeon experience. In a two stage procedure, relevant morbidity of the second operation has to be considered.Recently suggested approaches,laparoscopic lavage or interventional drainage without resection, remain a matter of debate.

    This paper reports on underbalance perforation flow experiments performed on reservoir and outcrop sandstones to investigate the perforation damaged zone. Cores from several different formations were perforated under reservoir conditions. After perforating, the cores were examined using CAT scans (Computer Aided tomography), thin sections and mercury porosimetry. In conjunction with these measurements, permeabilities in the damaged zone were measured using a minipermeameter and radial flow permeameter or were estimated from pore size distribution. The density and porosity of the damaged zone (at least for saturated rocks) is essentially the same as that in the undamaged rock. The damaged zone is not compacted, contrary to suggestions made in earlier work. However, the creation of this zone involves the destruction of large pores. The volume lost from these pores is replaced by microfractures created when rock grains are fractured by penetration of the shaped charge jet. This reduction in the average pore size causes a reduction in the permeability with the damaged zone. Although direct measurement of this permeability was made difficult by naturally occurring permeability variations, unambiguous measurements were obtained

    A perforated sigmoid colon cancer within an inguinal hernia is extremely rare. This unexpected finding is usually discovered during surgery and causes an unavoidable septic evolution. Here, we describe the case of an 84-year-old man who presented with fever, abdominal distension, and a painful, enlarged, left scrotum. A CT showed a left, incarcerated, inguinal hernia containing a perforated sigmoid adenocarcinoma (which was confirmed by histopathology). The possibility of an irreducible inguinal hernia in association with perforated sigmoid colon cancer should be considered in the array of diagnoses. A pre-operative CT scan would be helpful in facilitating an accurate diagnosis.

    Full Text Available Background: To study the aetiology, management and outcome of biliary perforations in paediatric age group. Patients and Methods: In a retrospective study, the records of patients presented with biliary peritonitis due to biliary perforations, managed from March 2006 to July 2009, are reviewed. Results: Eight male patients with biliary peritonitis due to biliary perforation were managed. These patients were divided in two groups, A and B. Group A, (n = 3 patients, had common bile duct (CBD perforation, and Group B (n=5 patients had gallbladder perforation. The presenting features were abdominal pain, fever, abdominal distension, vomiting, constipation, jaundice and signs of peritonism. The management of CBD perforations in Group A was by draining the site of perforation and biliary diversion (tube cholecystostomy. In Group B, the gallbladder perforations were managed by tube cholecystostomy in four patients and cholecystectomy in one patient, however, one patient had to be re-explored and cholecystectomy performed due to complete necrosis of gall bladder. There was no mortality in our series. All patients were asymptomatic on regular follow-up. Conclusion: Early optimal management of biliary perforations remarkably improved the very high mortality and morbidity that characterised this condition in the past.

    Peptic ulcer perforation is a common cause of emergency admission and surgery. This is the first study that documents the presentation and outcome of management in Irrua, Nigeria. This is a prospective study of all patients operated on for perforated peptic ulcer between April 1, 2010, and March 31, 2015. A structured questionnaire containing patients' demographics, operation findings, and outcome was filled upon discharge or death. There were 104 patients. 81 males and 23 females (M : F = 3.5 : 1). The age range was between 17 years and 95 years. The mean age was 48.99 years ± SD 16.1 years. The ratio of gastric to duodenal perforation was 1.88 : 1. Perforation was the first sign of peptic ulcer disease in 62 (59.6%). Pneumoperitoneum was detectable with plain radiographs in 95 (91%) patients. 72 (69.2%) had Graham's Omentopexy. Death rate was 17.3%. We note that gastric perforation is a far commoner disease in our environment. Perforation is often the first sign of peptic ulcer disease. We identify fasting amongst Christians as a risk factor for perforation.

    Introduction & Objective: Non-traumatic colon perforations are usually caused by malignancy, diverticulum and colitis. Stercoraceous perforation of the colon has rarely been reported in the literature. This lesion is assumed to be produced by the pressure from a hard scybalum resulting in a perforated ulcer with necrotic edges. We report a case of stercoraceous perforation of the cecum due to scybalum. Case: We report a 50-year-old man who had a severe abdominal pain from 3 days ago and had peritonitis in physical exam. He was admitted in Mars, 2005 at Mobasher Kashani Hospital in Hamadan and he was parapelegic from 8 months ago due to trauma in his medical history and then he had severe and chronic constipation that necessitated the use of cathartic drugs. We operated him with diagnosis of peritonitis, and perforation of cecum due to scybalum was seen and right hemicolectomy and colostomy and ileostomy was done. Conclusion: The most common site of colon perforation due to scybalum is rectosigmoid area and cecal perforation is a rare area in the literature. It is presented with peritonitis in old patients that have chronic constipation. It is difficult to diagnose this lesion preoperatively. This lesion was only 11% correctly diagnosed before operation and should be always suspected when a patient with chronic constipation suffers from sudden abdominal pain. Resection and colostomy is the treatment of choice in most situations.

    Full Text Available Purpose. To compare the long-term outcomes of infectious versus sterile perforated corneal ulcers after therapeutic penetrating keratoplasty in the United States. Methods. The charts of 45 consecutive eyes that underwent primary therapeutic penetrating keratoplasty for a perforated corneal ulcer at a single center were retrospectively reviewed. The perforated ulcers were classified as infectious or sterile and the underlying demographics, clinical features, and 36-month outcomes were compared among the two groups. Results. Mean follow-up among subjects was 38.6 (±6.9 months. Patients presenting with sterile perforated ulcers were more likely to have a peripheral perforation location (p=0.0333 and recurrence of the underlying disease condition (p=0.0321, require adjunctive surgical measures in the immediate postoperative period (p<0.0001, have reperforation after keratoplasty (p=0.0079, have worse best corrected visual acuity (p=0.0130, develop no light perception vision (p=0.0053, and require enucleation/evisceration (p=0.0252 when compared to the infectious perforated ulcer group. Conclusions. Sterile perforated corneal ulcers have a worse prognosis and may be more frequent than those caused by infectious disease in the United States compared to the developing world.

    Full Text Available Abdominal tuberculosis is defined as infection of the peritoneum, hollow or solid abdominal organs with Mycobacterium tuberculi . TB can affect any part of the gastrointestinal (GI tract including anus, peritoneum and hepatobiliary system. The peritoneum and the ileocaecal region are the most likely sites of infection. The clinical manifestations of abdominal tuberculosis are nonspecific and mimic various GI disorders and cause delay in diagnosis and management. This pa thology has several complications, including free intestinal perforation.

    Full Text Available Phytobezoar, a concretion of indigestible fibers derived from ingested vegetables and fruits, is the most common type of bezoar. Diospyrobezoar is a subtype of phytobezoar formed after excessive intake of persimmons (Diospyros kaki. We report the case of a diabetic man with a 5-day history of abdominal pain after massive ingestion of persimmons who developed signs of complicated small bowel obstruction. The patient had a previous history of Billroth II hemigastrectomy associated with truncal vagotomy to treat a chronic duodenal ulcer 14 years earlier. Since intestinal obstruction was suspected, he underwent emergency laparotomy that revealed an ileal obstruction with small bowel perforation and local peritonitis due to a phytobezoar that was impacted 15 cm above the ileocecal valve. After segmental intestinal resection, the patient had a good recovery and was discharged on the 6th postoperative day. This report provides evidence that diospyrobezoar should be considered as a possible cause of small bowel obstruction in patients who have previously undergone gastric surgery.

    A 45-year-old male, an alcohol addict with asthma, was found dead in his home, after several days of continued drinking. A forensic autopsy was performed 3days after the discovery of his death in order to specify the cause of death. A longitudinal perforation penetrating all layers of the esophagus measuring 1.8cm was present on the left wall approximately 2.0cm from the gastroesophageal junction. There were 1900mL of greenish to brownish turbid liquid in the left pleural cavity and 150mL of greenish viscous liquid in the stomach. Histopathologically, an infiltration of numerous neutrophils was evident in the submucosa layer, proper muscular layer, and serous membrane of the esophagus, corresponding to the esophageal laceration. The serum C-reactive protein (CRP) concentration was determined to be 3.1mg/dL. The alcohol concentrations were determined to be 1.49mg/g in the right cardiac blood, 1.31mg/g in the left cardiac blood, and 2.48mg/g in urine. Based upon the autopsy and histopathological findings, as well as the biochemical and toxicological analyses, we concluded that the cause of death was respiratory failure by pleural effusion, resulting from spontaneous esophageal perforation. This was the first report of a spontaneous esophageal perforation eventually causing respiratory failure. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Flexible micro-perforated panel has unique advantages in noise reduction due to its good flexibility compared with traditional rigid micro-perforated panel. In this paper, flexible micro-perforated panel was prepared by computer numerical control (CNC) milling machine. Three kinds of plastics including polyvinylchloride (PVC), polyethylene terephthalate (PET), and polyimide (PI) were taken as the matrix materials to prepare flexible micro-perforated panel. It has been found that flexible micro-perforated panel made of PET possessing good porosity and proper density, elastic modulus and poisson ratio exhibited the best acoustic absorption properties. The effects of various structural parameters including perforation diameter, perforation ratio, thickness and air gap have also been investigated, which would be helpful to the optimization of acoustic absorption properties.

    Peptic ulcer is a common disease affecting millions of people every year. Despite improved understanding and treatment of the disease, the number of patients admitted with duodenal peptic ulcer perforation has not decreased. Deaths from peptic ulcer disease overcome other common emergency situations. Laparoscopic repair of the perforated peptic ulcer (PPU) is the gold standard approach for simple perforation. However, in patients with large perforated chronic ulcers laparotomy with pyloroplasty is the standard treatment. It is generally accepted to perform open surgery in PPU emergencies because of the greater knowledge and experience gathered over the past decades and less potential harm for the patient or surgical complications. We present a case of successful laparoscopic pyloroplasty of a perforated duodenal ulcer with stenosis.

    2012-01-01

    A variety of corneal pathology can lead to corneal ulcers and perforations. A deep corneal ulcer may need surgical treatment to allow good volume restoration and reepithelisation. Corneal perforation must be sealed and when the perforation is large, the task of repairing the defect can be underwhelming. The elegant solution is the corneal transplant, but this is not always readily available, especially in undeveloped countries. We present here two cases with different solutions to seal the perforated cornea: the first one has a large peripheral defect and it is successfully sealed with scleral patch and the second one is central with small perforation and is successfully sealed with multilayered amniotic membrane. Both cases are followed for over 12 months and demonstrate good corneal restoration (both on clinical examination and corneal topography). Sclera and amniotic membrane can be used to seal corneal defects when corneal transplant is not readily available.

    Highlights: • Thick perforated plate is used in valve contained pipelines for noise control. • Finite element method (FEM) is used to simulate the acoustic response. • Transmission loss (TL) predictions of thick perforated plates are carried out. • Effects of shapes and mean flow on transmission loss are investigated. • A linear correction formula of maximum TL is proposed for thick perforated plate. - Abstract: Valve contained pipelines have witnessed a great growth and there exists a lot of noise caused by valves. Thick perforated plates are especially used is valve contained pipelines for the noise control, but there are limited literatures about its noise control performances under different structural parameter of thick perforated plates, which limits its popularization and application. In this paper, transmission loss (TL) predictions of various thick perforated plates are carried out to analyze the noise control performances. Finite element method (FEM) is implemented to simulate the acoustic response, and TL is achieved by the sound pressure of four points on both sides of the thick perforated plates. Adopted numerical method shows good agreements with the existing research works and the results indicate that reducing the margin of the plates can enhance TL of some frequencies. Similar to chamber mufflers, the maximum TL depends on the area ratio and the frequency range with the best noise control performance is related to the plate thickness. Meanwhile, the low velocity flow does not affect the TL curve so much and in the situation of supersonic flow, and the TL curve turns into a periodic shape, which may weaken the effects of noise control. Besides, based on the analytical solution of TL for the chamber muffler, a linear correction formula of maximum TL is proposed for the thick perforated plate. This work can give several advices for similar perforated plates design works and someone who are dealing with decreasing the noise effects from the

    Full Text Available OBJECTIVE: To report our experience with cystectomy and ileal neobladder for women with interstitial cystitis (IC. MATERIALS AND METHODS: Thirty-five female patients treated during 2000-2005 with the mean age of 45.9 ± 4.4 years were included in this study. All of them had experience suprapubic pain with irritative voiding symptoms and were diagnosed as having IC based on NIDDK criteria for at least 2 years. Conservative treatments had failed to relieve their symptoms; and therefore all of them agreed to undergo a bladder removal. For cystectomy, the urethra was cut 0.5 cm below the bladder neck, proximal to the pubourethral ligament, leaving the endopelvic fascia intact. An ileal segment of 65 cm was used to create the neobladder with the Studer's technique. RESULTS: All patients presented good treatment outcome with regard to both diurnal and nocturnal urinary control without any pain. Quality of life using the SF-36 questionnaire showed significant improvement of both physical health and mental health. Spontaneous voiding with minimal residual urine was found in 33 cases (94.3%, and the remaining 2 cases (5.7% had spontaneous voiding with residual urine and were placed on clean intermittent catheterization (CIC. Twelve out of 30 cases with sexually active ability had a mild degree of dyspareunia but without disturbance to sexual life. CONCLUSION: Bladder substitution by ileal neobladder for women who suffer from IC can be a satisfactory option after failure of conservative treatment. Resection of the urethra distal to the bladder neck can preserve continence and allow spontaneous voiding in almost all patients.

    2000-01-01

    Full Text Available This work is aimed at identifying factors associated with primary jejunum-ileal tumors malignancy, defining a prediction model with sensitivity, specificity and accuracy to distinguish malign from benign neoplasms. These tumors are rare, have highly unspecific presentation and, frequently, are diagnosed late. We reviewed the charts of 42 patients with primary jejunum-ileal tumors treated in the Department of General Surgery of Rio de Janeiro State University Hospital, Rio de Janeiro, RJ, Brazil, from 1969 to 1998. We performed bivariate analyses, based on chi² test, searching associations between tumors malignancy and demographic and clinical variables. Then logistic regression was employed to consider the independent effect of variables previously identified on malignancy risk. The malign tumors included 11 adenocarcinomas, 7 leiomyosarcomas, 5 carcinoids and 4 lymphomas; the benign tumors included 10 leiomyomas, 2 hamartomas, and single cases of adenoma, multiple neurilemoma and choristoma. The bivariate analyses indicated the association between malignancy and palpable abdominal mass (P = 0.003, period from signs and symptoms onset to diagnosis (P = 0.016, anemia (P = 0.020, anorexia (P = 0.003, abdominal pain (P = 0.031, weight loss (P = 0.001, nausea and vomit (P = 0.094, and intestinal obstruction (P = 0.066; no association with patients demographic characteristics were found. In the final logistic regression model, weight loss, anemia and intestinal obstruction were statistically associated with the dependent variable of interest. Based only on three variables -- weight loss, anemia and intestinal obstruction -- the model defined was able to predict primary jejunum-ileal tumors malignancy with sensitivity of 85.2%, specificity of 80.0%, and accuracy of 83.3%.

The subsequent arrival of isotope in the colon was quantified by gamma-scintigraphy and colonic filling curves were obtained. Studies were performed during fasting (n = 5) cnd 2.5 h after either a low residue meal (n = 5) or a meal made high in residue (n = 5) by adding 4 g of guar. The time for 50% of the isotope to reach the colon (T50) was significantly accelerated after both meals, being 72 +/- 15 min for the high residue meal and 62 +/- 8 min for the low residue meal, compared with 183 +/- 37 min (p less than 0.01) in the 5 fasting subjects. Although the addition of guar did not alter T50 significantly, it did cause a significant fall in the rate of colonic filling, implying increased isotope dilution. Delay at the ileocolonic junction, as shown by plateaus in the middle of the colonic filling curves, was uncommon. Hold-up was significant in only 2 of 10 postprandial and 2 of 5 fasting studies. Rates of ileocolonic transit could not be related to either a mean ileal motility index or the occurrence of specific ileal motor patterns immediately proximal to the ileocolonic junction. Fasting ileocolonic transit was characteristically erratic but could not be related to interdigestive migrating motor complexes, which were rarely observed in the last 60 cm of ileum. We conclude that ileocolonic transit in humans is related to the rate at which material accumulates in the ileum, being rapid postprandially and slow and erratic during fasting. This method yields consistent results and could be used to define further factors that influence ileocolonic inflow.

    S-1 is an oral agent containing tegafur (a prodrug of 5-fluorouracil) that is used to treat various cancers, but adverse effects are frequent. Two pilot clinical studies have suggested that lentinan (LNT; β-1,3-glucan) may reduce the incidence of adverse effects caused by S-1 therapy. In this study, we established a murine model for assessment of gastrointestinal toxicity associated with S-1 and studied the effect of LNT. S-1 was administered orally to BALB/c mice at the effective dose (8.3mg/kg, as tegafur equivalent) once daily (5days per week) for 3weeks. Stool consistency and intestinal specimens were examined. We investigated the effect of combined intravenous administration of LNT at 0.1mg, which is an effective dose in murine tumor models. We also investigated the effect of a single administration of S-1. During long-term administration of S-1, some mice had loose stools and an increase in apoptotic bodies was observed in the ileal crypts. An increase in apoptotic bodies was also noted after a single administration of S-1 (15mg/kg). Prior or concomitant administration of LNT inhibited the increase in apoptotic bodies in both settings. Administration of LNT also increased the accumulation of CD11b + TIM-4 + cells in the ileum, while depletion of these cells by liposomal clodronate diminished the inhibitory effect of LNT on S-1 toxicity. Combined administration of LNT with S-1 led to a decrease in apoptotic bodies in the ileal crypts, possibly because LNT promoted phagocytosis of damaged cells by CD11b + TIM-4 + cells.

    Cardiac tamponade caused by perforation of the cardiac wall is a rare complication related to central venous catheter (CVC) placement. A 71-year-old female with a previous history of moderate aortic stenosis and kidney transplantation was admitted to hospital due to global heart failure and worsening of allograft function. Intensified hemodialysis was commenced through a CVC placed in the right subclavian vein. Chest radiography revealed catheter tip in the right atrium and no signs of pneumothorax. Thorough diagnostics outruled immediate life-threatening conditions, such as myocardial infarction and pulmonary embolism. However, not previously seen, 2 cm thick pericardial effusion without repercussion on the blood flow was visualized during echocardiography, predominantly reclining the free surface of the right atrium, with fibrin scar tissue covering the epicardium - it was the spot of spontaneously recovered cardiac wall perforation. Follow-up echocardiogram performed before the discharge showed regression of the previously found pericardial effusion.

  20. Palatal perforation: A rare complication of postanesthetic necrosis

    Full Text Available The everyday practice of dentistry relies heavily on achieving adequate local anesthesia. Even though the safety record of local anesthetic agents is high, complications do occur. Palate is a favorable site for soft-tissue lesions. Various factors such as direct effects of the drug, blanching of the tissues during injection, relatively poor blood supply, and reactivation of the latent forms of herpes can all promote to tissue ischemia and a lesion in the palate. Among various complications, anesthetic necrotic ulcer is a rare and uncommon condition occurring mostly in the hard palate possibly after a local anesthetic infiltration. The ulceration is often deep and shows spontaneous but delayed healing. If proper treatment is not instituted on time, the necrosis can reach deep into the bone causing sequestrum formation and ultimately leading to palatal perforation. Here, we report a case of palatal perforation in a male patient followed by surgical interventions and follow-up.

    Full Text Available Abstract Objective: To identify the computed tomography findings suggestive of intestinal perforation by an ingested foreign body. Materials and Methods: This was a retrospective study of four cases of surgically proven intestinal perforation by a foreign body, comparing the computed tomography findings with those described in the literature. Results: None of the patients reported having ingested a foreign body, all were over 60 years of age, three of the four patients used a dental prosthesis, and all of the foreign bodies were elongated and sharp. In all four patients, there were findings indicative of acute abdomen. None of the foreign bodies were identified on conventional X-rays. The computed tomography findings suggestive of perforation were thickening of the intestinal walls (in all four cases, increased density of mesenteric fat (in all four cases, identification of the foreign body passing through the intestinal wall (in three cases, and gas in the peritoneal cavity (in one case. Conclusion: In cases of foreign body ingestion, intestinal perforation is more common when the foreign body is elongated and sharp. Although patients typically do not report having ingested such foreign bodies, the scenario should be suspected in elderly individuals who use dental prostheses. A computed tomography scan can detect foreign bodies, locate perforations, and guide treatment. The findings that suggest perforation are thickening of the intestinal walls, increased mesenteric fat density, and, less frequently, gas in the peritoneal cavity, often restricted to the point of perforation.

    The regional specialization of intestinal immune cells is affected by the longitudinal heterogeneity of environmental factors. Although the distribution of group 3 innate lymphoid cells (ILC3s) is well characterized in the lamina propria, it is poorly defined in Peyer's patches (PPs) along the intestine. Given that PP ILC3s are closely associated with mucosal immune regulation, it is important to characterize the regulatory mechanism of ILC3s. Here, we found that terminal ileal PPs of specific pathogen-free (SPF) mice have fewer NKp46 + ILC3s than jejunal PPs, while there was no difference in NKp46 + ILC3 numbers between terminal ileal and jejunal PPs in antibiotics (ABX)-treated mice. We also found that butyrate levels in the terminal ileal PPs of SPF mice were higher than those in the jejunal PPs of SPF mice and terminal ileal PPs of ABX-treated mice. The reduced number of NKp46 + ILC3s in terminal ileal PPs resulted in a decrease in Csf2 expression and, in turn, resulted in reduced regulatory T cells and enhanced antigen-specific T-cell proliferation. Thus, we suggest that NKp46 + ILC3s are negatively regulated by microbiota-derived butyrate in terminal ileal PPs and the reduced ILC3 frequency is closely associated with antigen-specific immune induction in terminal ileal PPs.

    Metastases from ileal neuroendocrine tumors (NETs) to the myocardium are rare and generally seen in patients with widespread metastatic NET disease. The objectives of this investigation were to describe the frequency of intracardiac metastases in ileal NET patients examined by (68)Ga-DOTA-TOC-PET/CT and to describe the cases in detail. All (68)Ga-DOTA-TOC-PET/CT examinations performed at the Karolinska University Hospital since 2010 until April 2012 were reviewed. In all, 128 out of 337 examinations were in patients with ileal NETs. Four patients had seven myocardiac metastases, yielding a frequency of 4.3 % in patients with ileal NETs. One patient had cardiac surgery while three were treated with somatostatin analogs. The cardiac metastases did not affect the patients' activity of daily life. (68)Ga-DOTA-TOC-PET/CT is an established imaging modality in identifying cardiac metastases in ileal NETs. Prospective studies are needed to confirm the true clinical value of (68)Ga-DOTA-TOC-PET/CT in detecting cardiac metastases in both ileal and non-ileal NETs.

    Full Text Available One of the causes of non-healing periapical pathosis in endodontically treated tooth is root perforation. This can occur pathologically by resorption and caries, iatrogenically during endodontic therapy (zip, strip, furcal perforations. Root perforation results in bacterial contamination, periradicular tissue injury, inflammation, and bone resorption. The purpose of this case report is to describe endodontic retreatment and surgical management of a longstanding periapical lesion on maxillary lateral incisor, associated with perforation and osseous defects using mineral trioxide aggregate (MTA. Although the majority of bone support and root dentin was damaged, an attempt was made to repair the defect and restore the tooth. After the surgical intervention and root canal treatment, the perforation was subsequently sealed with MTA. Later, the root was reinforced with composites and the tooth was restored with direct veneer. Conclusion: Four-and-a-half year (54 months recall examination showed no evidence of periodontal breakdown, no symptoms of further deterioration, and complete healing of periradicular lesions when examined by radiography. This case report presents a treatment strategy that could improve the healing process and beneficial outcomes for patients with perforation and osseous defect.

  13. Current management of peptic ulcer perforations

    Perforation is a life-threatening complication of peptic ulcer disease. Smoking and use of non-steroidal anti-inflammatory drugs are important risk factors for perforation. Diagnosis is made clinically and confirmed by the presence of pneumoperitoneum on radiographs. Nonoperative management is successful in patients identified to have a spontaneously sealed perforation proven by water-soluble contrast gastroduodenogram. Operative management consists of the time-honoured practice of mental patch closure, but now this can be done by laparoscopic methods. The practice of addition of acid-reducing procedures is currently being debated though it continues to be recommended in good-risk patients. Laparoscopic approaches to closure of duodenal perforation are now being applied widely and may become the gold standard in the future especially in patients with < 10 mm perforation size presenting within the first 24 hours of onset of pain. The role of Helicobacter pylori in duodenal ulcer perforation is controversial and more studies are needed to answer this question though recent indirect evidence suggests that eradicating H pylori may reduce the necessity for adding acid reducing procedures and the associated morbidity. Perforation is a life-threatening complication of peptic ulcer disease. The management of peptic ulcer disease has evolved over the decades, due to advances in operative techniques, bacteriology and pharmacology. While the recognition of the role of Helicobacter pylori (H. pylori) in peptic ulceration has resulted in a paradigm shift in the management of uncomplicated peptic ulcers, debate continues about the appropriate management of perforated duodenal bulb and prepyloric ulcers. A new dimension has been added to this controversy by the advent of laparoscopic techniques for closing the perforation. A Medline search of all articles dealing with the management of peptic ulcer perforation published after 1985 was undertaken. The short listed articles were

    Multiple magnet ingestion during childhood may result in emergency situations. A single magnet may be discharged with intestinal peristalsis, but multiple magnets may stick together and cause significant intestinal complications. Here we present a case with intestinal perforation due to ingestion of multiple magnets and metal pieces. An eight-year-old girl presented with abdominal pain and vomiting. She had abdominal tenderness and defense on the physical examination. Abdominal X-ray showed air and fluid levels. Metallic images were not considered at first as important in the diagnosis. Abdominal ultrasonography was reported as acute appendicitis. During the abdominal exploration, the appendix was normal, but there were dense adherences around the ileum and cecum. After adhesiolysis, intestinal perforations were seen in the cecum and 15 and 45 cm proximal to the cecum. Magnet and metal pieces were present in the perforated segments. Wedge resection and primary repair was performed. There were no postoperative complications, and she was discharged on the postoperative fifth day. Pediatric surgeons should be aware of the complications of multiple magnet ingestion. If the patient has a history of multiple magnet ingestion, follow-up with daily abdominal X-rays should be done, and in cases where magnets seem to cluster together or if acute abdominal signs develop, surgical exploration should be considered.

  15. Sound transmission through a finite perforated panel set in a rigid baffle: A fully coupled analysis

    Sound transmission through a fluid-loaded finite perforated panel set in an infinite unperforated rigid baffle is considered. Using a fully coupled formulation in the 2-D wavenumber domain, the transmitted pressure due to an incident plane wave is obtained. The change in the panel resonances caused by the perforations is accounted for. The formulation also takes into account the self- and inter-modal coupling coefficients arising due to the fluid-loading effect. The derivation is almost entirely analytical with numerical computations done at the very end. Transmission loss (TL) curves are plotted for various cases and the physics is discussed. Along the way an uncoupled calculation is also done for the sake of comparison. The results are mainly for a light medium like air. For a light medium, in general, the perforate impedance is lower than the panel impedance. Thus, most of the transmission happens through the perforations. The panel velocity contribution is insignificant and hence the uncoupled calculation is adequate. In general, the absolute perforate impedance increases with increasing frequency. So does the TL. At low frequencies, because the resistive component of the hole impedance increases, the absolute perforate impedance rises. Thus, the TL curves rise at the lower frequencies. This effect is prominent for sub-millimeter hole radii, i.e., for micro-perforations. An important issue with the TL values for perforated panels is that they sometimes acquire negative values at low frequencies. This apparent anomaly is resolved by showing that at low frequencies there is an additional power component that flows from the baffle region onto the panel. Upon inclusion of this additional term, the TL values remain positive at all frequencies.

    We encountered multiple cases in which the US appearance of ruptured appendicitis mimicked intussusception, resulting in diagnostic and therapeutic delay and multiple additional imaging studies. To explore the clinical and imaging discriminatory features between the conditions. Initial US images in six children (age 16 months to 8 years; 4 boys, 2 girls) were reviewed independently and by consensus by three pediatric radiologists. These findings were compared and correlated with the original reports and subsequent US, fluoroscopic, and CT images and reports. All initial US studies demonstrated a multiple-ring-like appearance (target sign, most apparent on transverse views) with diagnostic consensus supportive of intussusception. In three cases, US findings were somewhat discrepant with clinical concerns. Subsequently, four of the six children had contrast enemas; two were thought to have partial or complete intussusception reduction. Three had a repeat US examination, with recognition of the correct diagnosis. None of the US examinations demonstrated definite intralesional lymph nodes or mesenteric fat, but central echogenicity caused by debris/appendicolith was misinterpreted as fat. All showed perilesional hyperechogenicity that, in retrospect, represented inflamed fat ''walling off'' of the perforated appendix. There were four CTs, all of which demonstrated a double-ring appearance that correlated with the US target appearance, with inner and outer rings representing the dilated appendix and walled-off appendiceal rupture, respectively. All six children had surgical confirmation of perforated appendicitis. Contained perforated appendicitis can produce US findings closely mimicking intussusception. Clinical correlation and careful multiplanar evaluation should allow for sonographic suspicion of perforated appendicitis, which can be confirmed on CT if necessary. (orig.)

    Perforation of jejunal diverticulum is a rare complication. Here, we report a case of jejunal diverticulum penetration with surrounding ectopic pancreas. An 83-year-old female patient was admitted to our department with acute onset of severe abdominal pain lasting for half a day. Abdominal computed tomography showed outpouching of the small intestine that contained air/fluid, with multiple surrounding air bubbles in the mesentery of the small intestine. She was diagnosed with penetration of the small intestine, and an emergency laparotomy was indicated. The penetrated jejunal diverticulum was identified ~20-cm distal to the ligament of Treitz. Partial resection of the jejunum was performed, and her postoperative course was uneventful. The pathological findings confirmed diverticulum penetration into the mesentery and severe inflammation at the site, with surrounding ectopic pancreas. Furthermore, the pancreatic ducts were opened through the penetrated diverticulum. This rare case shows that the ectopic pancreas might have caused penetration of jejunal diverticulum owing to the pancreatic duct opening through the diverticulum.

    To describe a technique for covering defects of the fingertips: the innervated digital artery perforator (IDAP) flap. A total of 17 patients were treated with an IDAP flap. The size of the flaps varied between 2 ×1 cm and 3.5 × 2 cm. Postoperative evaluation of the patients consisted of the Semmes-Weinstein Monofilament test, static 2-point discrimination, patient satisfaction, extension loss, and an investigation into complications. All IDAP flaps survived completely, and no patients required secondary interventions. The mean follow-up period was 7 months (range, 6-10 mo). The Semmes-Weinstein monofilament test results ranged from 3.22 to 3.84. The static 2-point discrimination in the flaps ranged from 2 mm to 4 mm (mean, 3.4 mm) compared with a range of 2 mm to 3 mm (mean, 2.7 mm) on the contralateral hand. There were no joint contractures in the reconstructed fingertips, although 2 patients developed mild hook nail deformity. One patient experienced mild cold intolerance, and 1 patient exhibited mild postoperative hypersensitivity. The advantages of the IDAP flap include minimally invasive surgery; a reliable, versatile flap; and the ease of the technique for different-sized fingertip defect reconstructions with few complications. The IDAP flap may be useful in fingertip amputations when the amputated part is not suitable for replantation. Therapeutic IV. Copyright © 2013 American Society for Surgery of the Hand.

    To evaluate the usefulness of high-resolution ultrasonography (US) for the differentiation of acute perforated appendicitis from non-perforated appendicitis. The high-resolution US features in 96 patients (49 males, 47 females; mean age, 33.8 years; age range, 4-80 years) with pathologically proven acute appendicitis were evaluated. The following US findings were evaluated for differentiation of acute perforated appendicitis from non-perforated appendicitis: circumferential loss of the echogenic submucosal layer, periappendiceal fluid collection, disruption of the serosal layer, asymmetrical wall thickening, maximum overall diameter > 10.5 mm, and the presence of appendicoliths. The sensitivity and specificity of the US features in the diagnosis of acute perforated appendicitis were calculated. All of the US findings, except for appendicoliths, were significantly more common in the acute perforated appendicitis group (p < 0.001). The sensitivity of circumferential loss of the echogenic submucosal layer, periappendiceal fluid collection, disruption of the serosal layer, asymmetrical wall thickening, maximum overall diameter > 10.5 mm, and the presence of appendicoliths was 85.4, 73.2, 68.3, 70.7, 80.5, and 36.6%, respectively, while the specificity was 65.5, 89.1, 96.4, 98.2, 81.8, and 80.0%, respectively. High-resolution US was found to be useful for differentiating acute perforated appendicitis from non-perforated appendicitis.

    The role of magnetic resonance imaging (MRI) in pediatric appendicitis is increasing; MRI findings predictive of appendiceal perforation have not been specifically evaluated. To assess the performance of MRI in differentiating perforated from non-perforated appendicitis. A retrospective review of pediatric patients undergoing contrast-enhanced MRI and subsequent appendectomy was performed, with surgicopathological confirmation of perforation. Appendiceal diameter and the following 10 MRI findings were assessed: appendiceal restricted diffusion, wall defect, appendicolith, periappendiceal free fluid, remote free fluid, restricted diffusion within free fluid, abscess, peritoneal enhancement, ileocecal wall thickening and ileus. Two-sample t-test and chi-square tests were used to analyze continuous and discrete data, respectively. Sensitivity and specificity for individual MRI findings were calculated and optimal thresholds for measures of accuracy were selected. Seventy-seven patients (mean age: 12.2 years) with appendicitis were included, of whom 22 had perforation. The perforated group had a larger mean appendiceal diameter and mean number of MRI findings than the non-perforated group (12.3 mm vs. 8.6 mm; 5.0 vs. 2.0, respectively). Abscess, wall defect and restricted diffusion within free fluid had the greatest specificity for perforation (1.00, 1.00 and 0.96, respectively) but low sensitivity (0.36, 0.25 and 0.32, respectively). The receiver operator characteristic curve for total number of MRI findings had an area under the curve of 0.92, with an optimal threshold of 3.5. A threshold of any 4 findings had the best ability to accurately discriminate between perforated and non-perforated cases, with a sensitivity of 82% and specificity of 85%. Contrast-enhanced MRI can differentiate perforated from non-perforated appendicitis. The presence of multiple findings increases diagnostic accuracy, with a threshold of any four findings optimally discriminating between

    Context • As a critical concept in acupuncture, acupuncture points, or acupoints for short, are currently believed to be 3-dimensional structures composed of skin, muscles, tendons, nerves, blood vessels, lymph nodes, and other special tissues. No known specific tissue or organ has been confirmed to be an acupoint. However, from a microsurgeon's point of view, a special vascular structure exists around each acupoint (ie, perforators or arterioles of 0.3-1.5 mm that pierce deeply through the fascia). Objective • The current research team investigated the theory that perforators are the anatomical basis of acupoints. Design • A reference list of acupoints and of perforators near the acupoints was proposed, and the distributions were analyzed. Using the World Health Organization (WHO) list, "Standard Acupuncture Point Locations in the Western Pacific Region," 2 experienced acupuncturists identified the needling depth and angle as well as verified the acupoint locations. Perforators with amplitudes of 1 cm or more were identified by 3 veteran microsurgeons. Setting • The study was carried out in an osteopathic research center at the 89th Hospital of the People's Liberation Army, in Weifang, Shandong, China. From October 2013 to October 2014, patients who required skin flap transplantation were enrolled for observation. Outcome Measures • To evaluate the theory, the current research team observed subcutaneous perforating points in flap donor sites and operative incision areas and compared those points with the acupoints located by acupuncturists. Results • The perforators and acupoints were found to be closely correlated. Several distribution patterns of acupoints and perforators have emerged and further confirmed the research team's theory. Conclusions • The hypothesis could facilitate theoretical understanding of the mechanism and essence of acupuncture.

    Full Text Available Abstract Introduction Recent data suggest that mucosal abnormalities can occur even in the duodenum, jejunum, and distal ileum of cirrhosis patients. We present a case of portal hypertensive enteropathy in a cirrhosis patient shown by capsule endoscopy and the effect of transjugular intrahepatic portosystemic shunt on the ileal pictures. Case presentation An 83-year-old Caucasian woman was admitted to our hospital for anemia and a positive fecal occult blood test. An upper gastrointestinal endoscopy revealed small varices without bleeding signs and hypertensive gastropathy. Colonoscopy was negative. To rule out any other cause of bleeding, capsule endoscopy was performed; capsule endoscopy revealed severe hyperemia of the jejunum-ileal mucosa with active bleeding. Because of the persistence of anemia and the frequent blood transfusions, not responding to β-blocker drugs or octreotide infusion, a transjugular intrahepatic portosystemic shunt was performed. Anemia improved quickly after the transjugular intrahepatic portosystemic shunt, and no further blood transfusion was necessary in the follow-up. The patient developed portal encephalopathy two months later and was readmitted to our department. We repeated the capsule endoscopy that showed a significant improvement of the gastric and ileal mucosa without any signs of bleeding. Conclusion Hypertensive enteropathy is a rare condition, but it seems more common with the introduction of capsule endoscopy in clinical practice. This case shows that the jejunum can be a source of bleeding in cirrhosis patients, and this is the first demonstration of its resolution after transjugular intrahepatic portosystemic shunt placement.

  6. High-fiber rye diet increases ileal excretion of energy and macronutrients compared with low-fiber wheat diet independent of meal frequency in ileostomy subjects

    Full Text Available Background: Whole-grain foods and cereal dietary fiber intake is associated with lower body weight. This may partly result from lower energy utilization of high-fiber diets. Objective: In the present study, the impact on ileal excretion of energy and macronutrients in response to a rye bread high-fiber diet compared to a refined wheat low-fiber diet was investigated. Furthermore, the effect of meal frequency on apparent absorption of nutrients was studied for the first time. Design: Ten participants that had undergone ileostomy consumed standardized iso-caloric diets, including low-fiber wheat bread (20 g dietary fiber per day for 2 weeks followed by high-fiber rye bread (52 g dietary fiber per day for 2 weeks. The diets were consumed in an ordinary (three meals per day and a nibbling (seven meals per day meal frequency in a cross-over design. Ileal effluents were collected during 24 h at the third day of each of the four dietary periods and analyzed for gross energy and nutrient contents. Results: The results showed that intake of rye bread high-fiber diet compared to the refined wheat low-fiber diet caused an increase in ileal excretion of energy and macronutrients. The effect was independent of meal frequency. This suggests that a high intake of rye may result in lower availability of macronutrients for small intestinal digestion and absorption. A regular intake of rye may therefore have implications for weight management.

  7. Gut luminal endogenous protein: implications for the determination of ileal amino acid digestibility in humans.

    2012-08-01

    The true ileal digestibility assay provides the most informative measure of digestibility to assess bioavailability of amino acids in foods for humans. To determine 'true' estimates of ileal amino acid digestibility, requires that endogenous amino acids present in digesta at the terminal ileum be quantified. The amounts of endogenous amino acids in ileal digesta can be determined after feeding an animal or human a protein-free diet (traditional approach) or by various methods after giving a protein-containing diet. When the protein-free method has been applied with adult human subjects an overall mean value (three separate studies) for endogenous ileal nitrogen flow of 800 mg N/d has been reported. This value is considerably lower than a comparable value obtained after feeding protein of 1852 mg N/d (mean of four separate studies), and thus endogenous ileal N and amino acids should be measured under conditions of protein alimentation. There is some confusion concerning the terminology used to define digestibility, with the term "true" digestibility having different adopted meanings. Here, true amino acid digestibility is defined as apparent amino acid digestibility corrected for the basal amino acid losses determined after giving either a protein-free or a protein-containing diet. Basal losses should be determined at a defined dry-matter and protein intake. The protein-free diet approach to determining endogenous amino acids is considered unphysiological and basal losses refer to ileal endogenous amino acid flows associated with digesta dry-matter flow, and not including "specific" effects of dietary factors such as non starch polysaccharides and anti nutritional factors. Arguments are advanced that the enzyme hydrolysed protein/ultra filtration method may be suitable for routine application with a cannulated pig model, to obtain physiologically-valid basal estimates of ileal endogenous amino acids to allow calculation of true ileal amino acid digestibility in the

    A 73-year-old woman was transferred to our department due to severe abdominal pain with peritonitis. Her laboratory data showed that her white blood cell count was elevated to more than 50,000/mm 3 . Antibodies to HTLV-I were positive and we made the diagnosis of adult T-cell leukemia (ATL). Emergency laparotomy was performed and revealed two separate small perforations of the ileum, requiring bowel resection. Immunohistochemistry for cytomegalovirus (CMV) antigen revealed positive staining in the intestinal stromal cells. Despite surgery and antiviral therapy with ganciclovir, she died after 28 days. Adult T-cell leukemia patients may present acute abdominal pain due to intestinal perforation caused by CMV infection. We should be aware of CMV infection as one of the pathogens causing acute abdominal crises such as massive hemorrhage or visceral perforation.

    Peptic ulcer perforation is a serious complication of peptic ulcer disease with a significant morbidity and mortality. To evaluate 76 patients operated for peptic ulcer perforation and analyse the associated factors in Zewditu Memorial Hospital, Addis Ababa from September 2006 to August 2008. A retrospective analysis of medical records of 76 patients who were operated up on for perforated peptic ulcer over a two year period (2006-2008). The male to female ratio was 6.6:1 with a mean age being 31.5 years. The most common presenting symptom was abdominal pain in 76 (100%) patients. History of smoking and khat chewing was documented in 53/64 (82.8%) and 48/64 (75%) of the patients respectively. Twenty five per cent of the patients gave no history of previous peptic ulcer disease. Seventy patients (92.1%) presented after 48 hours of their illness. The mean hospital stay was 14.5 days. Leucocytosis was found in 31.6% of the cases. Sixty five (85.5%) patients had duodenal ulcer perforation. Postoperative complications occurred in 24 (31.6%) patients. Twelve (15.8%) patients died in the hospital. Early presentation of patients and change in life style may reduce morbidity and mortality in patients with peptic ulcer perforation.

    A case of nasal septal perforation secondary to systemic bevacizumab therapy for ovarian cancer is reported. Bevacizumab is a vascular endothelial growth factor A (VEGF-A) inhibitor that is becoming more widely utilized in the oncologic community. There is only one prior report of septal perforation secondary to bevacizumab in the Otolaryngology specific literature. The purpose of this report is: 1) to raise awareness and discuss the literature surrounding the sinonasal complications of bevacizumab and 2) provide workup and treatment recommendations based on the sum of the available literature. We review the clinical record of a 59year old patient who presented with an anterior septal perforation while taking bevacizumab therapy for ovarian cancer. She had mild symptoms. Her oncologist held bevacizumab and topical moisture therapy was started. After several weeks, the perforation remained stable and bevacizumab was restarted for her ovarian cancer. Bevacizumab is associated with both septal perforation and more widespread sinonasal toxicity. These lesions tend to produce only mild symptoms and can usually be managed conservatively. The decision to hold bevacizumab therapy should be made in conjunction with the patient and medical oncologist. Otolaryngologists should be aware of the toxicity from this increasingly common oncologic therapy. Copyright © 2017 Elsevier Inc. All rights reserved.

  12. Oriented cluster perforating technology and its application in horizontal wells

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available An oriented cluster perforating technology, which integrates both advantages of cluster and oriented perforating, will help solve a series of technical complexities in horizontal well drilling. For realizing its better application in oil and gas development, a series of technologies were developed including perforator self-weight eccentricity, matching of the electronic selective module codes with the surface program control, axial centralized contact signal transmission, and post-perforation intercluster sealing insulation. In this way, the following functions could be realized, such as cable-transmission horizontal well perforator self-weight orientation, dynamic signal transmission, reliable addressing & selective perforation and post-perforation intercluster sealing. The combined perforation and bridge plug or the multi-cluster perforation can be fulfilled in one trip of perforation string. As a result, the horizontal-well oriented cluster perforating technology based on cable conveying was developed. This technology was successfully applied in unconventional gas reservoir exploitation, such as shale gas and coalbed methane, with accurate orientation, reliable selective perforation and satisfactory inter-cluster sealing. The horizontal-well oriented cluster perforating technology benefits the orientation of horizontal well drilling with a definite target and direction, which provides a powerful support for the subsequent reservoir stimulation. It also promotes the fracturing fluid to sweep the principal pay zones to the maximum extent. Moreover, it is conductive to the formation of complex fracture networks in the reservoirs, making quality and efficient development of unconventional gas reservoirs possible.

    The commercial code, CFX-5, was used in the numerical calculation of the pressure loss in water flow through perforated plates. Studies for adequate definition of both turbulence model and mesh refinement have been carried through, especially near the wall. Simulations were performed on the plates with different orifices configurations (number and diameter), keeping the same cross-section coefficient (flow area of the perforated plate / pipe section before the plate). The results have been compared with the obtained by the Handbook of Hydraulic Resistance of I. E. Idelchik, reference in this kind of estimate. The differences between the methodologies were small when applying the turbulence model k-e and a high degree of mesh refinement. The study aims to contribute with the validation process of the numerical methodology in the determination of pressure drop in elements with similar geometry to a perforated plate, such as the bottom end piece of the nuclear fuel element.

    Perforated appendicitis is associated with an increased morbidity and length of stay. "Fast track" protocols have demonstrated success in shortening hospitalization without increasing morbidity for a variety of surgical processes. This study evaluates a fast track pathway for perforated appendicitis. In 2013, a treatment pathway for perforated appendicitis was adopted by the Acute Care Surgery Service for patients having surgical management of perforated appendicitis. Interval appendectomy was excluded. Patients were treated initially with intravenous antibiotics and transitioned to oral antibiotics and dismissed when medically stable and tolerating oral intake. A retrospective review of patients managed on the fast track pathway was undertaken to analyze length of stay, morbidity, and readmissions. Thirty-four males and twenty-one females with an average age of 46.8 years underwent laparoscopic appendectomy for perforated appendicitis between January 2013 and December 2014. Pre-existing comorbidities included hypertension 42%, diabetes mellitus 11%, COPD 5% and heart disease 2%. No patient had conversion to open appendectomy. Average length of stay was 2.67 days and ranged from 1 to 12 days (median 2 days). Postoperative morbidity was 20% and included abscess (6 patients), prolonged ileus (3 patients), pneumonia (1 patient), and congestive heart failure (1 patient). Five patients were readmitted for abscess (3 patients), congestive heart failure (1 patient), and pneumonia (1 patient). A fast track pathway for perforated appendicitis produced shorter length of stay and acceptable postoperative morbidity and readmission. This offers the potential for significant cost savings over current national practice patterns. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The intrauterine device (IUD is a widely used, highly effective method of birth control. Uterine perforation is a rare yet serious complication and is usually seen during insertion of the IUD. A regular examination is necessary for follow-up. We present a patient with an IUD that had perforated the cervix. The diagnosis was made during routine gynecological examination, and the patient was treated in a timely manner before any complications such as ectopic pregnancy, intrauterine pregnancy, infection or irreversible harm to the cervix arose. This case stresses the importance of regular visits to maintain health and diagnose possible adverse effects of intrauterine contraceptive methods.

    Introduction: Gastro-duodenal perforations may be suspected in patients with history of ulceration, who present with acute pain and abdominal wall rigidity, but radiological findings in these cases may be unable to confirm a clinical diagnosis. The aim of our study was to report our experience in the diagnosis of gastro-duodenal perforation by conventional radiography, US and CT examinations. Material and methods: We retrospectively reviewed medical records of 166 consecutive patients who presented in the last 2 years to our institutions with symptoms of acute abdomen and submitted to surgery at the Emergency Unit of the ''A.Cardarelli'' Hospital of Naples with a surgical finding of perforated gastro-duodenal ulcer. The evidence of free intraperitoneal air on abdominal plain film was considered as a direct or suggestive finding of perforation. Evidence of intraperitoneal free fluid and/or reduced intestinal peristalsis at sonographic examination were considered indirect signs of gastro-duodenal perforation. Evidence of free peritoneal gas at CT was considered as a direct evidence of gastro-duodenal perforation. Results: Twenty patients underwent immediate surgery with no preoperative imaging evaluation, in 10 of them the site of perforation was found in a juxta-pyloric region and in the others at level of duodenum. In 146 patients submitted to serial radiological investigations before surgery, the site of perforation was in 56 (38.3%) duodenal, in 52 (35.6%) juxta-pyloric, in 28 (19.1%) gastric and in 10 (6.8%) pyloric. The cause of perforation was in all cases gastric or duodenal ulceration, in seven cases involving pancreatic parenchyma. In 110 (75.4%) patients with direct findings of perforation, in 94 cases (85.5%) the correct diagnosis was established on abdominal plain film, in two (1.8%) with radiographic and sonographic examinations and in 14 (12.7%) on CT findings.

    Familial adenomatous polyposis (FAP) is caused by a rare mutation of the adenomatous polyposis coli gene on Chromosome 5q. The risk of colorectal cancer in patients with FAP is nearly 100% and intensive endoscopic surveillance or prophylactic colectomy are mandatory. If extensive endoscopic surveillance is chosen, there is a cumulative risk of perforation and bleeding especially after polypectomy. We discussed the problems and options in the management of the late diagnosis of an iatrogenic perforation of the splenic flexure complicating endoscopic surveillance in FAP. We present a 35-year-old black African man with FAP who sustained a splenic flexure perforation following a colonoscopic polypectomy of a suspicious lesion. He underwent a splenic flexure resection and primary anastomosis that dehisced and the patient benefited from an emergency definitive colectomy and ileorectal anastomosis. Resection with primary anastomosis following iatrogenic perforation of the splenic flexure is not safe because of a high chance of anastomotic dehiscence. Following a late diagnosis in an unstable patient exteriorization of the perforation as a stoma is a better option prior to a definitive prophylactic colectomy.

    Full Text Available Cardiac perforation by pacemaker is a rare but potentially fatal complication. Acute perforations occurring within twenty-four hours of insertion of pacemaker can lead to hemopericardium, cardiac tamponade, and death. Hemothorax occurring as an acute complication of pacemaker insertion is reported but extremely rare. Previously, hemothorax and shock as a subacute complication following pacemaker insertion have not been reported. We report the case of an 85-year-old patient who presented with shock from hemothorax caused by pacemaker perforation, two weeks after insertion. Device interrogation showed normal function. Chest X-ray and echocardiogram missed lead dislocation and the diagnosis was made on computed tomogram (CT of the chest. Following surgical repair, a new ventricular pacemaker was placed transvenously in the right ventricular septum. This case illustrates that CT scan of the chest should be performed in all patients in whom cardiac perforation by pacemaker is suspected but not diagnosed on chest X-ray and echocardiogram. Normal functioning of pacemaker on device interrogation does not exclude perforation.

Following surgical repair, a new ventricular pacemaker was placed transvenously in the right ventricular septum. This case illustrates that CT scan of the chest should be performed in all patients in whom cardiac perforation by pacemaker is suspected but not diagnosed on chest X-ray and echocardiogram. Normal functioning of pacemaker on device interrogation does not exclude perforation.

    The etiology of nasal septal perforations involves iatrogenic, traumatic, inflammatory, infectious, neoplastic, and caustic causes. To ensure successful closure, an appropriate interpositional graft material should be selected, and this graft material should be covered with healthy tissue. The study included 18 New Zealand white rabbits weighing 2 to 2.5 kg. Nasal septal perforations were created in group 1. After the creation of defects in group 2, repair was performed with cartilage graft and bilateral mucoperichondrial advancement flaps. After septal nasal perforations in group 3, the defect was covered with fingernail and bilateral mucoperichondrial flaps. At week 12, the rabbits were sacrificed. The septum site that had been repaired with fingernail was intact. No nail exposition, wound site decomposition, or re-perforation was observed. No findings of a breach of the structural integrity of the fingernails or disintegration were encountered. Fingernails can be used as an interpositional graft material in place of cartilage in eligible cases for the repair of nasal septal perforations. Fingernails have several properties that enable their use in such cases, such as form preservation that is similar to cartilage, the lack of live cells, easy availability, and a lack of donor-site morbidity at removal.

    2008-01-01

    Full Text Available Spontaneous perforation of the extrahepatic biliary system is a rare presentation of ductal stones. We report the case of a twenty-year-old woman presenting at term with biliary peritonitis caused by common bile duct (CBD perforation due to an impacted stone in the distal common bile duct. The patient had suffered a single herald episode of acute gallstone pancreatitis during the third trimester. The patient underwent an emergency laparotomy, bile duct exploration, and removal of the ductal stone. The postoperative course was uneventful.

    2010-01-01

    ABSTRACT: INTRODUCTION: The occurrence of intussusception in adults is rare. The condition is found in 1 in 1300 abdominal operations and 1 in 100 patients operated for intestinal obstruction. The child to adult ratio is 20:1. CASE PRESENTATION: A 52-year-old Irish Caucasian woman was investigated for a 3-month history of intermittent episodes of colicky midgut pain and associated constipation. Ileocolonoscopy revealed a pedunculated lesion in the terminal ileum prolapsing into the caecum. Computed tomography confirmed a smooth-walled, nonobstructing, low density intramural lesion in the terminal ileum with secondary intussusception. A laparoscopic small bowel resection was performed. Histology revealed a large pedunculated polypoidal mass measuring 4 x 2.5 x 2 cm consistent with a submucosal lipoma. She had complete resolution of her symptoms and remained well at 12-month follow-up. CONCLUSION: This case highlights an unusual cause of incomplete small bowel obstruction successfully treated through interdisciplinary cooperation. Ileal lipomas are not typically amenable to endoscopic removal and require resection. This can be successfully achieved via a laparoscopic approach with early restoration of premorbid functioning.

    Conclusion : Involvement of mesenteric vasculature by granulomatous inflammation was commonly associated with the ulcerative type with perforation, suggesting that ischemia caused by vascular thrombosis is responsible for tissue breakdown. This implies that vasculitis plays an important role in the natural history of abdominal tuberculosis.

    The small bowel is responsible for most of the body's nutritional uptake and for the development of intestinal and systemic tolerance towards microbes. Nevertheless, the human small bowel microbiota has remained poorly characterized, mainly owing to sampling difficulties. Sample collection directly from the distal ileum was performed during radical cystectomy with urinary diversion. Material from the ileal mucosa were analysed using massive parallel sequencing of the 16S rRNA gene. Samples from 27 Caucasian patients were included. In total 280 unique Operational Taxonomic Units were identified, whereof 229 could be assigned to a species or a species group. The most frequently detected bacteria belonged to the genera Streptococcus, Granulicatella, Actinomyces, Solobacterium, Rothia, Gemella and TM7(G-1). Among these, the most abundant species were typically streptococci within the mitis and sanguinis groups, Streptococcus salivarius, Rothia mucilaginosa and Actinomyces from the A. meyeri/odontolyticus group. The amounts of Proteobacteria and strict anaerobes were low. The microbiota of the distal part of the human ileum is oral-like and strikingly different from the colonic microbiota. Although our patient population is elderly and hospitalized with a high prevalence of chronic conditions, our results provide new and valuable insights into a lesser explored part of the human intestinal ecosystem.

    Full Text Available Burkitt’s lymphoma (BL is rare, rapidly growing, and highly aggressive. Urgent commencement of chemotherapy is vital to prevent complications and promote a favourable prognosis. Any factor causing a delay in the initiation of chemotherapy will affect prognosis significantly. Intestinal perforation is a well-known complication with devastating consequences. It inevitably leads to a delay in the initiation of chemotherapy. There are few reports in the literature that discuss this complication. Furthermore, there are no reports of patients that have survived intestinal perforation occurring prior to the commencement of chemotherapy. We present a case of a 55-year-old male who survived perforation of advanced sporadic BL of the jejunum occurring prior to the commencement of chemotherapy. Critical aspects of the patients care are discussed.

    Choledochal cysts are a congenital disorder of the bile duct, usually presenting in childhood. As they cause weakening of the wall of the bile duct, any distal obstruction, infection or reflux of amylase-rich fluid in the biliary tract can predispose to spontaneous perforation. A 25-year-old pregnant woman at 35 weeks of gestation presented with acute abdominal and fetal distress. On emergency laparotomy, common bile duct perforations were detected. T-tube drainage and caesarean section were performed. A t-tube cholangiogram revealed the diagnosis of a choledochal cyst with an abnormal pancreatobiliary junction and chronic pancreatitis. The patient later underwent cyst excision with Roux en Y hepaticojejunostomy. Spontaneous choledochal cyst perforation in pregnancy can be successfully managed by a two-stage operation. 2014 BMJ Publishing Group Ltd.

  14. Establishment of tensile failure induced sanding onset prediction model for cased-perforated gas wells

    Directory of Open Access Journals (Sweden)

    Mohammad Tabaeh Hayavi

    2017-04-01

    Full Text Available Sand production is a challenging issue in upstream oil and gas industry, causing operational and safety problems. Therefore, before drilling the wells, it is essential to predict and evaluate sanding onset of the wells. In this paper, new poroelastoplastic stress solutions around the perforation tunnel and tip based on the Mohr–Coulomb criterion are presented firstly. Based on the stress models, a tensile failure induced sanding onset prediction model for cased-perforated gas wells is derived. Then the analytical model is applied to field data to verify its applicability. The results from the perforation tip tensile failure induced sanding model are very close to field data. Therefore, this model is recommended for forecasting the critical conditions of sand production analysis. Such predictions are necessary for providing technical support for sand control decision-making and predicting the production condition at which sanding onset occurs.

    Intestinal perforation caused by blunt trauma to an inguinal hernia is a very uncommon event. We present the case of a 55-year old man who suffered trauma to the inguinal area while playing soccer and later developed intense abdominal pain with no categorical signs of peritoneal irritation. Computed tomography scan at arrival showed a right inguinal hernia, with partial protrusion of the ileum, inflammatory changes of the mesenteric fat tissue inside the hernial sac, and free intraperitoneal fluid. Several hours later he developed hypotension and fever. An emergency laparotomy was performed, revealing ileum perforation with peritonitis. Intestinal perforation was repaired without intestinal resection. After surgery, the patient developed severe septic shock with multiple organ failure. He recovered without sequelae and was discharged 3 weeks later. This case emphasizes the potential clinical complications associated with this condition. Copyright © 2012 Elsevier Inc.

  19. Determination of the Fundamental Frequency of Perforated Rectangular Plates: Concentrated Negative Mass Approach for the Perforation

    Directory of Open Access Journals (Sweden)

    Kiran D. Mali

    2013-01-01

    Full Text Available This paper is concerned with a vibration analysis of perforated rectangular plates with rectangular perforation pattern of circular holes. The study is particularly useful in the understanding of the vibration of sound absorbing screens, head plates, end covers, or supports for tube bundles typically including tube sheets and support plates used in the mechanical devices. An energy method is developed to obtain analytical frequencies of the perforated plates with clamped edge, support conditions. Perforated plate is considered as plate with uniformly distributed mass. Holes are considered as concentrated negative masses. The analytical procedure using the Galerkin method is adopted. The deflected surface of the plate is approximated by the cosine series which satisfies the boundary conditions. Finite element method (FEM results have been used to illustrate the validity of the analytical model. The comparisons show that the analytical model predicts natural frequencies reasonably well for holes of small size.

    This letter introduces a modified design of membrane-type acoustic metamaterials (MAMs) with a ring mass and a perforation so that an airflow through the membrane is enabled. Simplified analytical investigations of the perforated MAM (PMAM) indicate that the perforation introduces a second anti-resonance, where the effective surface mass density of the PMAM is much higher than the static value. The theoretical results are validated using impedance tube measurements, indicating good agreement between the theoretical predictions and the measured data. The anti-resonances yield high low-frequency sound transmission loss values with peak values over 25 dB higher than the corresponding mass-law. - Highlights: • A new membrane-type acoustic metamaterial exhibiting negative density is presented. • The metamaterial design contains a ring mass with a perforation through the membrane. • The sound transmission loss exhibits narrow-band peaks much higher than the mass-law. • The emergence of the peaks is explained using a simple theoretical model. • Impedance tube measurements are used to validate the theoretical predictions.

    2014-03-28

    Here, we report on a case of acute phlegmonous gastritis (PG) complicated by delayed perforation. A 51-year-old woman presented with severe abdominal pain and septic shock symptoms. A computed tomography scan showed diffuse thickening of the gastric wall and distention with peritoneal fluid. Although we did not find definite evidence of free air on the computed tomography (CT) scan, the patient's clinical condition suggested diffuse peritonitis requiring surgical intervention. Exploratory laparotomy revealed a thickened gastric wall with suppurative intraperitoneal fluid in which Streptococcus pyogenes grew. There was no evidence of gastric or duodenal perforation. No further operation was performed at that time. The patient was conservatively treated with antibiotics and proton pump inhibitor, and her condition improved. However, she experienced abdominal and flank pain again on postoperative day 10. CT and esophagogastroduodenoscopy showed a large gastric ulcer with perforation. Unfortunately, although the CT showed further improvement in the thickening of the stomach and the mucosal defect, the patient's condition did not recover until a week later, and an esophagogastroduodenoscopy taken on postoperative day 30 showed suspected gastric submucosal dissection. We performed total gastrectomy as a second operation, and the patient recovered without major complications. A pathological examination revealed a multifocal ulceration and necrosis from the mucosa to the serosa with perforation.

    Uterine perforation is an uncommon complication of intrauterine device insertion, with an incidence of one in 1,000 insertions. Perforation may be complete, with the device totally in the abdominal cavity, or partial, with the device to varying degrees within the uterine wall. Some studies show a positive association between lactation and perforation, but a causal relationship has not been established. Very rarely, a device may perforate into bowel or the urinary tract. Perforated intrauterine devices can generally be removed successfully at laparoscopy. PMID:29386934

    Two of the most common liver abscess is anamoebic liver abscess and pyogenic liver abscess (PLA). PLA could be as singular or multiple abscesses. It is usually caused by Klebsiella pneumonia and Escherichia coli. Historically, PLA is usually caused by acute appendicitis, but with developed of surgical practice and microbiology, the number of events has decreased. Here we present a case of a39-year-old woman that developed a PLA after she had an appendectomy about six months ago. An ultrasonogram and abdominal scan showed an abscess in the right lobe. We performed paracentesis, and the result from the pus culturewas positive for Escherichia coli with Extended-Spectrum Beta-Lactamase (ESBL) (+) that showed the same as the culture from lesion taken from her appendix. This report emphasizes the fact that, nowadays we still found Pyogenic liver abscess after peritonitis appendix perforation.

    Thirty-nine patients (forty-four joints) who had been diagnosed as having meniscus perforation of the temporomandibular joint by inferior joint space arthrography and had been treated by surgical procedures were evaluated retrospectively. Information of clinical findings, arthrotomographic findings and surgical findings was collected on a standardized form and evaluated. The results were as follows: 1. On the 34 patients of 38 joints which were surgically confirmed perforation of meniscus or its attachments of the temporomandibular joint, there were 29 females and 5 males (5.8:1). The average age was 36 years (range 17 to 70). 2. The common clinical findings of group that had meniscus displacement without reduction and with perforation were pain on the affected joint and limitation of mouth opening. In the group showing meniscus displacement with reduction and with perforation the common clinical findings were pain and clicking on the affected joint. 3. 32 joints (84.2%) were arthrotomographically anterior meniscus displacement without reduction and with perforation, 6 joints (15.8%) showed anterior meniscus displacement with reduction and with perforation. 4. Joints categorized arthrotomographically as having meniscus displacement without reduction and with perforation were less likely to have full translation of the condyle in comparison with the normal or meniscus displacement with reduction and with perforation groups (p<0.05) 5. The arthrographic findings of 44 joints having meniscus perforation were compared with surgical findings, there were 6 false positive findings of meniscus perforation, the reliability of arthrographic findings of meniscus perforation was a 86.4% correlation with surgical findings. 6. On the site of perforations of 38 joints which were surgically confirmed perforation of meniscus or its attachments, twenty-three of perforations (60.5%) were in location at the junction of the meniscus and posterior attachment, fourteen (36.9%) were

    1996-01-01

    Pouchitis in ileal anal anastomosis represents an important clinical complication after restorative proctocolectomy. Acute and chronic inflammation of the reservoir is a frequent event sometimes associated with villous atrophy and colonic metaplasia. After ileal pouch anastomosis, twenty-one patients affected by ulcerative colitis were studied. An image analyzer CAS 200 (Becton Dickinson) was utilized to evaluate the DNA intranuclear content in every biopsy. In two cases abnormal DNA distribution was observed, and in one case a poliploid pattern was seen. Abnormal DNA distribution was also present in colonic metaplasia. Therefore, image analysis for the detection of DNA aneuploidy may be of additional value together with histologic parameters in follow up, in order to exclude transformation of the ileal mucosa in neoplastic epithelia.

    Full Text Available Dimensional changes are a common occurrence in impressions, either during or after impression taking. It produces a difference in the dimensions of the object and the model, which leads to the restoration being ill-fitted. Several causal factors have been proposed such as friction between the impression material and the teeth, the bulk of the impression material, the type of impression materials used, the impression technique, the pouring time and many others. The exact causal factor is still unknown and the dimensional change mechanism is still poorly understood. The objective of this research was to investigate the role of the perforation on the ring trays in producing dimensional changes in the impression by using perforated and non-perforated ring trays. Alginate impressions were made on the frustum of cone metal master die with a 7.08 mm base diameter, 7.03 mm top diameter and 9.23 mm height using perforated and non-perforated ring trays with 9.40 mm in diameter and 14.17 mm in height. The dimensional change was determined by comparing the dimension of the dental stone die and its metal master die. The results showed that the percentage of dimensional changes that occurred by using perforated ring tray were (+ 0.56±0.40 on the top area, (- 3.54±2.92 on base area and (+ 1.54±0.83 in height, respectively. As compared to using non-perforated ring trays, the percentage of dimensional changes that occurred were (- 0.49±0.49 on top area, (- 8.76±3.95 on base area and (+ 1.19±0.71 in height, respectively. There was a significant difference in the direction of the dimensional changes on both the top areas, but not in the base areas and height.

    Full Text Available Objective: to compare clinical manifestations, course, mental status in duodenal ulcer (DU patients with a history of perforated ulcer and its uncomplicated course.Subjects and methods. One hundred and thirteen patents with DU were examined. Group 1 included 61 patients with uncomplicated DUand Group 2 comprised 52 patients with a history of perforated ulcer. A comparison group consisted of 20 patients who had undergone laparotomy. Physical and mental status examinations, esophagogastroduodenoscopy (EGDS, and 24-hour pH-metry were performed.Results. Classical pain syndrome was observed in 75 % of the patients with uncomplicated DU. Prior to perforation, the pain and dyspeptic syndromes were distinguished only by a significantly lower degree in Group 2; following perforation, the pain syndrome was recorded more frequently, it was more extensive, meal-unrelated, and similar to that in the patients who had undergone laparotomy and had diminished appetite (36.5 %. EGDS showed that the complicated course was accompanied by the significantly higher incidence of erosive esophagitis (21.2 %, gastritis (51.9 %, duodenitis (25.0 %, multiple ulcers (28.8 %, and larger ulcers. 24-hour pH-metry indicated that the level of hyperacidity in Group 2 was higher and the circadian intragastric pH variations were less marked than those in uncomplicated DU. The patients with a history of perforated ulcer showed a high rate of anxiety and depressive changes. Conclusion. In complicated DU, marked monotonic hyperacidity causes common erosive-ulcerative lesions in the gastroduodenal area in relatively mild pain syndrome, late referrals, and long-term ulcer healing. After perforation followed by wound closure, the pain and dyspeptic syndromes become more pronounced, which is associated with anxiety and depressive changes in the mental status, as well as with early referrals and less healing time.

    The purpose of this study was to develop and validate a method of directly measuring ileal bile acid absorption efficiency during a single enterohepatic cycle (first-pass ileal clearance). This has become feasible for the first time because of the availability of the synthetic gamma-labeled bile acid 75Selena-homocholic acid-taurine (75SeHCAT). Together with the corresponding natural bile acid cholic acid-taurine (labeled with 14C), SeHCAT was infused distal to an occluding balloon situated beyond the ampulla of Vater in six healthy subjects. Completion of a single enterohepatic cycle was assessed by obtaining a plateau for 75SeHCAT activity proximal to the occluding balloon, which prevented further cycles. Unabsorbed 75SeHCAT was collected after total gut washout, which was administered distal to the occluding balloon. 75SeHCAT activity in the rectal effluent measured by gamma counter was compared with that of absorbed 75SeHCAT level measured by gamma camera and was used to calculate first-pass ileal clearance. This was very efficient (mean value, 96%) and showed very little variation in the six subjects studied (range, 95%-97%). A parallel time-activity course in hepatic bile for 14C and 75Se during a single enterohepatic cycle, together with a ratio of unity for 14C/75Se in samples obtained at different time intervals, suggests that 75SeHCAT is handled by the ileum like the natural bile acid cholic acid-taurine. Extrapolation of 75SeHCAT first-pass ileal clearance to that of the natural bile acid therefore seems justifiable. In a subsidiary experiment, ileal absorption efficiency per day for 75SeHCAT was also measured by scanning the gallbladder area on 5 successive days after the measurement of first-pass ileal clearance. In contrast with absorption efficiency per cycle, absorption efficiency per day varied widely (49%-86%)

    Full Text Available Purpose Ureteric substitution using the Yang-Monti principle was reported as a modification of simple ileal ureter replacement. In this study, we evaluate its safety, surgical outcome and impact on renal function. Materials and Methods Sixteen patients underwent ileal ureter replacement using the Yang-Monti principle to overcome long ureteric defects. Exclusion criteria included patients with elevated serum creatinine > 1.8 mg/dL, inflammatory bowel syndrome or irradiated bowel. Antireflux implantation into the bladder was performed in 12 patients while 4 patients with intact healthy lower ureters underwent distal ileal-ureteral anastomosis. Follow-up protocol was carried out for up to 3 years in 9 patients. Results No intra-operative or postoperative mortality or significant complications occurred. There were minor complications in the form of urinary leakage that necessitated prolonged ureteric stenting in one patient, superficial wound infection in another one and 3 patients developed treatable urinary tract infection without late harmful effects. During follow up, no excess mucus production or metabolic abnormalities were encountered. All patients had preserved renal function (improved in 13 patients and stabilized in 3 without any evidence of urinary obstruction. Conclusions The reconfigured ileal segment for ureteric substitution is a safe technique with an excellent outcome. It uses short ileal segments for reconstruction of an ileal tube of adequate length and optimal caliber that permits easy antireflux implantation into the bladder so it is not associated with excess mucus production or metabolic abnormalities and offers a durable preservation of renal function without urinary obstruction.

  9. GATA4 Is Sufficient to Establish Jejunal Versus Ileal Identity in the Small IntestineSummary

    Full Text Available Background & Aims: Patterning of the small intestinal epithelium along its cephalocaudal axis establishes three functionally distinct regions: duodenum, jejunum, and ileum. Efficient nutrient assimilation and growth depend on the proper spatial patterning of specialized digestive and absorptive functions performed by duodenal, jejunal, and ileal enterocytes. When enterocyte function is disrupted by disease or injury, intestinal failure can occur. One approach to alleviate intestinal failure would be to restore lost enterocyte functions. The molecular mechanisms determining regionally defined enterocyte functions, however, are poorly delineated. We previously showed that GATA binding protein 4 (GATA4 is essential to define jejunal enterocytes. The goal of this study was to test the hypothesis that GATA4 is sufficient to confer jejunal identity within the intestinal epithelium. Methods: To test this hypothesis, we generated a novel Gata4 conditional knock-in mouse line and expressed GATA4 in the ileum, where it is absent. Results: We found that GATA4-expressing ileum lost ileal identity. The global gene expression profile of GATA4-expressing ileal epithelium aligned more closely with jejunum and duodenum rather than ileum. Focusing on jejunal vs ileal identity, we defined sets of jejunal and ileal genes likely to be regulated directly by GATA4 to suppress ileal identity and promote jejunal identity. Furthermore, our study implicates GATA4 as a transcriptional repressor of fibroblast growth factor 15 (Fgf15, which encodes an enterokine that has been implicated in an increasing number of human diseases. Conclusions: Overall, this study refines our understanding of an important GATA4-dependent molecular mechanism to pattern the intestinal epithelium along its cephalocaudal axis by elaborating on GATA4’s function as a crucial dominant molecular determinant of jejunal enterocyte identity.

    Cardiac tamponade due to aortic injury after blunt trauma is a rare and potentially fatal injury. Most aortic injuries caused by blunt trauma present as aortic dissection or rupture of the aortic isthmus. Several cases of delayed aortic injury have been reported. However, all of these injuries were observed in the descending aorta because they had been caused by a posterior rib fracture. We report the first case of cardiac tamponade associated with delayed ascending aortic perforation 2 weeks after blunt trauma. The patient was an 81-year-old man. In cases of blunt chest trauma, delayed ascending aortic injury causing cardiac tamponade is possible associated with various causes such as direct injury by fractured rib or delayed aortic perforation of initial blunt injury.

    Perforation of the abdominal esophagus caused by nasogastric tube (NGT) intubation has been rarely reported in adults. A 73-year-old man was admitted to our hospital with pneumonia. He had been bedridden long-term and had previously undergone a gastrectomy for gastric ulcer. Since admission was prolonged, and he required enteral feeding because of his inability to swallow, a NGT was inserted blindly. The next day, he had a high fever and abdominal pain. Abdominal computed tomography scan revealed that the tube was inserted through the wall of the abdominal esophagus into the abdominal cavity. In the emergency surgery, we sutured the perforated site of abdominal esophagus and patched it with lesser omentum. The postoperative course was good. Abdominal esophageal perforation due to NGT insertion is very rare. The cause of perforation was suggested to be an abnormal deformity created by adhesion due to previous distal gastrectomy and long-term bedridden status. A chest X-ray usually is performed to confirm the position of the NGT tube. In this case, a frontal radiographic view apparently showed the NGT placed in the stomach. When NGT is inserted to such patients, frontal and lateral radiographic views or fluoroscopic guidance should be obtained. Copyright © 2018. Published by Elsevier Ltd.

    Case report. To share our successful experience in treating 1 case of esophageal perforation after anterior revision cervical spine surgery with open-wound management. Early diagnosis and surgical treatment is widely adopted in the management of esophageal complications after anterior cervical spine surgery, but the management of wound after surgical repair of esophageal perforation is rarely discussed. One patient underwent revision anterior cervical spine surgery because of displaced hardware and poor alignment of cervical spine. Esophageal perforation was incurred intraoperatively and found on the first postoperative day. Repair surgery was carried out immediately afterward. During the surgery, esophageal perforation was closed with a suture, and reinforced with a sternocleidomastoid muscle flap. The wound was loosely closed with aspirating drainage. Two days after the surgery, the patient began to show signs of recurrent esophageal leakage and severe secondary wound infection. The wound was then reopened completely before a continuous irrigation and drainage system was positioned in place. In 12 weeks, the esophageal perforation healed without complications or loosening of instrumentation. Open-wound management succeeded in this patient after surgical repair of esophageal perforation caused by revision anterior cervical spine surgery. 4.

    Ingestion of liquid nitrogen is rare but carries catastrophic complications related to barotrauma to the gastrointestinal tract. We describe a case of ingestion of liquid nitrogen followed by gastric perforation and respiratory insufficiency and discuss the mechanism of injury and management of this condition. Liquid nitrogen is widely available and is frequently used in classroom settings, in gastronomy, and for recreational purposes. Given the potentially lethal complications of ingestion, regulation of its use, acquisition, and storage may be appropriate.

    A 45-year-old female was admitted to the hospital with a 1-week history of right upper abdominal pain and nausea. Ultrasonography showed a thickened duodenum with infiltration. Subsequent gastroscopy did not reveal any abnormalities. CT scan showed a foreign body perforation at the duodenum and a liver abscess (Fig. 1A,B). A diagnostic laparoscopy was performed. During the operation, the abscess was drained (Fig. 2A,B) and a sewing needle was removed (Fig. 3A,B). The patient claimed to have no recollection of swallowing the needle and made a quick recovery. Although rare, gastrointestinal perforations due to ingested foreign bodies most frequently occur at ileocecal, rectosigmoid, and duodenal regions[1]. Sewing needle perforations into the liver have been reported in children, adults, and psychiatric cases. Symptoms can vary from mild gastric pain to signs of peritonitis[2]. "Wait and see" is recommended for asymptomatic patients with no complications. Symptomatic patients (e.g., liver abscess) need surgical intervention[1,2,3].

    Abstract: Appendicitis is common in paediatric surgical praxis, but extremely rare in newborn infants. We report a premature male newborn from a twin pregnancy with gestational age of 31(+4) weeks, birth-weight 1580g, who underwent a laparotomy because of perforation. The baby was admitted to NICU after birth with transitory respiratory failure and early onset neonatal sepsis. MS-Staphylococcus epidermidis was isolated from blood culture, gastric contents and all peripheral specimens, C-reactive protein values were elevated after birth and significantly increased before surgery; thrombocytopenia and mild anemia were found. The control blood culture showed Candida albicans. At day 25 after birth life threatening deterioration occurred: feculent vomiting, progressing distension and palpable rigidity of the abdomen, absence of peristalsis, respiratory distress. Abdominal radiograph showed significantly distension of the intestines, air liquid levels, and discrete signs of pneumoperitoneum. The baby was transferred to the surgery with the diagnosis NEC with perforation. Appendicitis acuta gangrenosa perforativa and peritonitis fibrinopurulenta totalis were found intra-operatively but without signs of NEC. Appendectomy and sanitation of the abdominal cavity were carried out. The histological result confirmed gangrenous perforative appendicitis and purulent necrotic peritonitis. The postoperative course was unremarkable. The boy was transferred to the neonatology on day 33 of life and discharged home 12 days later. Despite of the low incidence of neonatal appendicitis, it should be taken into consideration if unclear abdominal symptoms occur in the neonatal period. Early surgical intervention contribute to a reduction of potential complications.

    This study evaluates the amount of remaining tooth structure and possibility of producing lateral perforation following the use of different diameters of parallel-sided Parapost drills in groups of different canal curvatures (0 degrees-15 degrees, 16 degrees-25 degrees, 26 degrees technique, Parapost drills #1, #2, and #3 were used in the different canal groups for the preparation of a post space. Standardized digital radiographs were taken before the post space preparation and after each Parapost drill application. Four horizontal lines (a, b, c, and d) were drawn at equal distances on these images, starting from the pulp chamber floor moving apically at 2 mm increments. There were no significant differences between the different curvature groups at the a, b, c, and d levels for the critical level of the remaining tooth structure (multiple comparison test; p>0.05). However, in considering root perforation, both at the inner and outer side of the roots, there were statistically significant differences at "c" and "d" levels in group 3 (#3 drill) without taking into account the root curvature (ANOVA; p< 0.5). None of the specimens showed strip perforation.

    The purpose of this study was to determine possible mechanisms of 17 gastric and esophageal perforations that occurred during laparoscopic Nissen fundoplication. Specific details of each perforation relating to mechanism of injury, surgeon experience, diagnosis, treatment, and outcome were obtained. For each perforation, an attempt was made to accurately determine the mechanism of perforation. Three mechanisms accounted for the 17 perforations, the majority of which occurred within the first ten laparoscopic Nissen fundoplications performed by the surgeon. Ten perforations resulted from injuries related to improper retroesophageal dissection, five occurred during passage of the bougie dilator or nasogastric tube, and two occurred after surgery secondary to suture pullthrough. Six patients received a delayed diagnosis, which adversely affected outcome. Most of the perforations were successfully managed by primary closure and wrap to include the repair. Morbidity was significantly increased for perforations recognized late. One death, attributed to sepsis, occurred in association with a delay in diagnosis. Gastric and esophageal perforations are serious complications of the new laparoscopic method of Nissen fundoplication. The mechanisms of these complications are specifically related to limitations of the laparoscopic technique. Prevention of these potentially lethal complications requires a full understanding of the detailed anatomy of the gastroesophageal region and awareness of the recognized mechanisms of perforation.

    Abdominal scars are no longer a contra-indication for abdominal perforator flap harvesting. Few research data exists about the regeneration potential of the abdominal wall's perforator system. Therefore, previous abdominoplasty with umbilical transposition is an absolute contra-indication for a DIEaP-flap (deep inferior epigastric artery perforator flap). A 50-year-old patient required a breast reconstruction of the right breast, 10 years after an abdominoplasty with undermining of the superior abdomen and umbilical transposition. The patient was scheduled for a free lumbar artery perforator (LaP) flap. The preoperative computed tomography-angiography mapping showed nice lumbar perforators and to our surprise a good-sized DIEa perforator in the peri-umbilical region. The DIEa perforator on the right hemi-abdomen, consisting of two veins and one artery, was pulsatile and found suitable in size. A classical flap harvest and transfer was further performed. This case report is the first in which a dominant perforator is found in the area of undermining after a full abdominoplasty with umbilical repositioning. Further investigations regarding the nature and timing of re-permeation or regeneration of perforators after abdominoplasty are to be done. Nevertheless, we are convinced that with appropriate perforator mapping and a suitable plan B, previous abdominoplasty is no longer an absolute but a relative contra-indication for performing DIEaP-flap.

    The previously described "perfusion zones" of the abdominal wall vasculature are based on filling of the deep inferior epigastric artery (DIEA) and all its branches simultaneously. With the advent of the DIEA perforator flap, only a single or several perforators are included in supply to the flap. As such, a new model for abdominal wall perfusion has become necessary. The concept of a "perforator angiosome" is thus explored. A clinical and cadaveric study of 155 abdominal walls was undertaken. This comprised the use of 10 whole, unembalmed cadaveric abdominal walls for angiographic studies, and 145 abdominal wall computed tomographic angiograms (CTAs) in patients undergoing preoperative imaging of the abdominal wall vasculature. The evaluation of the subcutaneous branching pattern and zone of perfusion of individual DIEA perforators was explored, particularly exploring differences between medial and lateral row perforators. Fundamental differences exist between medial row and lateral row perforators, with medial row perforators larger (1.3 mm vs. 1 mm) and more likely to ramify in the subcutaneous fat toward the contralateral hemiabdomen (98% of cases vs. 2% of cases). A model for the perfusion of the abdominal wall based on a single perforator is presented. The "perforator angiosome" is dependent on perforator location, and can mapped individually with the use of preoperative imaging.

    wavelength corresponding to its specific molecular vibrations. This thermal energy heats the resonator and leads to its thermal expansion followed by a decrease of the tensile stress in the resonator. In turn it eventually causes the resonance frequency to shift towards lower values. However, further...... development of this approach was curbed by difficult and inefficient coupling of the IR light beam to a nanometer-sized resonator. In addition, readout of vibration was done by laser Doppler vibrometer, a precise but bulky and expensive instrument. These issues hindered a realworld application of the NAM......-IR method. In order to overcome them, string resonators were replaced by membranes. A reliable sampling technique was maintained by adding perforation to membranes and thereby essentially getting membrane porous filters. Membranes gave also access to fully integrated magnetic transduction that allowed...

    Full Text Available Tsunamis have damaged bridges to various extents in the 2004 Indian Ocean Tsunami. This paper reports an experimental investigation of the effect of perforations in the girders and parapets on the horizontal tsunami loads. The results reveal that the maximum pressures impinging on the front face of the pier and deck are 4.5 and 3 times the hydrostatic pressure at 80mm nominal wave heights. The percentage of force reduction of the bridge deck with 10% perforated girders and 60% perforated parapets is found to be close to the percentage of perforation area in the deck. However, it is also noted that perforations in the bridge deck can substantially reduce the tsunami forces acting on it throughout the force time history. Thus, less damage to the bridge is anticipated for the bridge deck with perforations in girders and parapets.

    Small incision refractive lenticule extraction (SMILE) is an effective laser procedure that treats myopia. This research was to describe a novel approach to treat corneal ulcer or perforation using the corneal lenticules obtained from SMILE and to evaluate the safety and effectiveness of tectonic keratoplasty with femtosecond laser intrastromal lenticule (TEKIL). A total of twenty patients (22 eyes) were monitored for at least 6 months and were assessed using slit lamp microscopy, optical coherence tomography, and best-corrected visual acuity (BCVA). Postoperative complications throughout the study period were recorded. Corneal ulcer in 14 patients (16 eyes) and corneal perforation in six patients (6 eyes) were treated with TEKIL. The patients were ten females and ten males, with a mean age of 58.5 ± 16.3 years (range: 16-81 years). In this study, the most causes of corneal ulcer or perforation were immunologic causes (54.5%). After TEKIL procedure, global integrity was achieved in all cases. No immune rejection or perforation was detected. The mean BCVA improved from 0.17 ± 0.20 preoperatively to 0.27 ± 0.25 postoperatively at the final follow-up (t = 2.095, P = 0.052). The postoperative BCVA improved in 12 eyes (54.5%) and maintained in nine eyes (40.9%). Vision function successfully maintained in all eyes (100%). In three cases, corneal ulcers were treated by reoperation of TEKIL at 3 months after the initial surgery for the reason that the residual corneal thickness was corneal ulcer and perforation in the condition of emergency and donor shortage.

    Goat milk is used as an alternative to cow milk for the production of infant formulas. However, little is known about the protein quality and, specifically, about the digestible AA pattern of goat milk formulas compared with their cow milk counterparts. In this study, the true ileal AA digestibility

    The immediate results of 37 restorative proctocolectomies are reported comparing morbidity of stapled vs manual procedures. The stapled technique is easier and faster but does not reduce the incidence of leakages and pelvic sepsis related to the ileal pouch. It seems, though, to be more useful in reducing the morbidity related to the ileoanal anastomosis.

    The author reports a recently recognised physical examination finding, otoscope fogging, for perforated tympanic membrane. Otoscope fogging is defined as condensation forming in the view field of the otoscope while inspecting the ear. In the setting of occult perforation secondary to the inability to visualise the entire tympanic membrane, otoscope fogging may provide the clinician with valuable information since medical management may differ if perforation is present.

    Peptic ulcer perforation continues to be a major surgical problem. In this study, risk factors that influence morbidity and mortality in perforated peptic ulcer disease were examined. Files of 148 patients who were included in the study due to peptic ulcer perforation between January 2006 and December 2010 were retrospectively analyzed. Data regarding age, gender, complaints, time elapsed between onset of symptoms and hospital admission, physical examination findings, co-morbid diseases, laboratory and imaging findings, length of hospital stay, morbidity and mortality were recorded. The study group included 129 (87.2%) male and 19 (12.8%) female patients. The mean age was 51.7±20 (15-88) years. Forty five patients (30.4%) had at least one co-morbid disease. In the postoperative period, 30 patients (20.3%) had complications. The most common complication was wound infection. Mortality was observed in 27 patients (18.2%). The most common cause of mortality was sepsis. Multivariate analysis revealed age over 60 years, presence of co-morbidities and Mannheim peritonitis index as independent risk factors for morbidity. Age over 60 years, time to admission and Mannheim peritonitis index were detected as independent risk factors for mortality. Early diagnosis and proper treatment are important in patients presenting with peptic ulcer perforation.

    Alzheimer's disease is a neurodegenerative disorder that affects mostly the elderly. The main histopathological markers are the senile plaques formed by amyloid-β peptide (Aβ) aggregates that can perforate the plasma membrane of cells, increasing the intracellular calcium levels and releasing synaptic vesicles that finally lead to a delayed synaptic failure. Several membrane proteins and lipids interact with Aβ affecting its toxicity in neurons. Here, we focus on NMDA receptors (NMDARs) as proteins that could be modulating the association and neurotoxic perforation induced by Aβ on the plasma membrane. In fact, our results showed that decreasing NMDARs, using enzymatic or siRNA approaches, increased the association of Aβ to the neurons. Furthermore, overexpression of NMDARs also resulted in an enhanced association between NMDA and Aβ. Functionally, the reduction in membrane NMDARs augmented the process of membrane perforation. On the other hand, overexpressing NMDARs had a protective effect because Aβ was now unable to cause membrane perforation, suggesting a complex relationship between Aβ and NMDARs. Because previous studies have recognized that Aβ oligomers are able to increase membrane permeability and produce amyloid pores, the present study supports the conclusion that NMDARs play a critical protective role on Aβ actions in hippocampal neurons. These results could explain the lack of correlation between brain Aβ burden and clinically observed dementia.

  17. Heat transfer and flow friction correlations for perforated plate matrix heat exchangers

    Perforated plate matrix heat exchangers (MHE) are constructed of high conductivity perforated plates stacked alternately with low conductivity spacers. They are being increasingly used in many cryogenic applications including Claude cycle or Reversed Brayton cycle cryo-refrigerators and liquefiers. Design of high NTU (number of (heat) transfer unit) cryogenic MHEs requires accurate heat transfer coefficient and flow friction factor. Thermo-hydraulic behaviour of perforated plates strongly depends on the geometrical parameters. Existing correlations, however, are mostly expressed as functions of Reynolds number only. This causes, for a given configuration, significant variations in coefficients from one correlation to the other. In this paper we present heat transfer and flow friction correlations as functions of all geometrical and other controlling variables. A FluentTM based numerical model has been developed for heat transfer and pressure drop studies over a stack of alternately arranged perforated plates and spacers. The model is validated with the data from literature. Generalized correlations are obtained through regression analysis over a large number of computed data.

    The ulnar forearm fasciocutaneous flap (UFFF) is a favourable alternative to the radial forearm flap when thin and pliable tissue is required. The precise anatomy of the cutaneous perforators of UFFF has not been previously reported. The position of cutaneous perforators>0.5 mm was recorded while raising 52 consecutive free UFFFs in 51 patients at our Centre. Three (6%) UFFFs in two patients demonstrated direct cutaneous supply through a superficial ulnar artery, a known anatomic variance. There was no cutaneous perforator>0.5 mm in one flap. Among the remaining 48 dissections, an average of 3 (range, 1-6) cutaneous perforators were identified. Ninety-four percent of these forearms demonstrated at least one perforator>0.5 mm within 3 cm, and all had at least one perforator within 6 cm of the midpoint of the forearm. Proximal perforators were more likely to be musculo-cutaneous through the edge of flexor carpi ulnaris or flexor digitorum superficialis, while mid- to distal perforators were septo-cutaneous. UFFF skin paddle designed to overlie an area within 3 cm of the midpoint between the medial epicondyle and the pisiform is most likely to include at least one cutaneous perforator from the ulnar artery, without a need for intra-operative skin island adjustment. This novel anatomic finding and other practical generalisations are discussed to facilitate successful elevation of UFFF.

  19. Frequency of wound infection in non-perforated appendicitis with use of single dose perforative antibiotics

    International Nuclear Information System (INIS)

    Ali, K.; Latif, H.; Ahmad, S.

    2015-01-01

    Antibiotics are used both pre and post-operatively in acute appendicitis for preventing wound infection. It has been observed that the routine use of post-operative antibiotics is not necessary in cases of non-perforated appendicitis as only prophylactic antibiotics are sufficient to prevent wound infection. The aim of this study was to see the frequency of wound infection in non-perforated appendicitis with single dose preoperative antibiotics only. Method: This observational study was conducted at the Department of Surgery, Ayub Medical College, Abbottabad from May to November 2014. A total of 121 patients with non-perforated appendicitis were included in the study. Only single dose preoperative antibiotics were used. The patients were followed for wound infection till 8th post-operative day. Results: 121 patients, 56(46.28%) male and 65(53.72%) female were included in the study. The mean age of patients was 27.41 ± 7.12 years with an age range of 18 to 45 years. In the entire series, 7(5.78%) patients developed wound infection. The infection was minor which settled with conservative therapy. Prophylactic antibiotics were found efficacious in 114(94.21%) patients. There was no significant association between wound infection and age and gender. Conclusion: Single dose preoperative antibiotics were found effective in controlling post-operative wound infection without the need of extending the antibiotics to post-operative period in cases of non-perforated appendicitis.

    We report extraordinary effects in the transmission of sound through periodically perforated plates, supported by both measurements and theory. In agreement with recent observations in slit arrays, M. H. Lu et al. [Phys. Rev. Lett. 99, 174301 (2007)10.1103/PhysRevLett.99.174301], nearly full transmission is observed at certain resonant frequencies, pointing out similarities of the acoustic phenomena and their optical counterpart. However, acoustic screening well beyond that predicted by the mass law is achieved over a wide range of wavelengths in the vicinity of the period of the array, resulting in fundamentally unique behavior of the sound as compared to light.

    Full Text Available Dengue viral infections have become one of major emerging infectious diseases in the tropics. Acute abdomen occurring in dengue viral infection is not uncommon. The spectrums of acute surgical emergencies which raise suspicion of an abdominal catastrophe in patients presenting with dengue fever include acute pancreatitis, acute acalculous cholecystitis, non-specific peritonitis and very rarely acute appendicitis. The presence of low white cell count and platelet count can raise suspicion of a diagnosis of dengue in a patient presenting with acute abdominal pain, during a dengue epidemic. We herein report three patients with dengue fever who had appendicular perforation during the course of their viral fever.

    Full Text Available Acute appendicitis is the most common non-obstetric reason of abdominal pain in the pregnancy, causing significant increase of maternal and fetal morbidity and mortality. This is a case report of a patient in the third trimester of pregnancy in whom perforated appendicitis caused purulent peritonitis. She was operated as an emergency case and cesarean section was performed. After the surgery and antibiotic administration according to drug susceptibility test, her postoperative course was uneventful. Delayed diagnosis of the acute appendicitis leads to increased rate of appendicular perforation, with numerous maternal and fetal complications. In cases of suspected appendicitis during pregnancy, surgical exploration is indicated, either by laparoscopy or laparotomy. Laparotomy is the method of choice in cases after 20 weeks of pregnancy and whenever signs of diffuse peritonitis are present.

    Full Text Available BACKGROUND Chronic venous insufficiency presents with a spectrum of clinical features ranging from pain or heaviness of affected limbs to non-healing ulcers over the lower limbs and usually require some form of surgical intervention, performing direct perforator vein division preferably by subfascial endoscopic perforator ligation surgery for perforator incompetence, as despite aggressive conservative therapy including compression, lifestyle modification and venotonic medications which are of high cost treatment with increased risk of increasing symptoms. MATERIALS AND METHODS A prospective longitudinal clinical study of 30 patients selected by systematic sampling method from November 2014 to September 2015 at our institution was conducted to determine the results of subfascial endoscopic perforator vein surgery (SEPS in perforator incompetence. RESULTS For venous clinical severity scoring pre operatively and after 3 weeks post-surgery, the mean for VCSS pre-operatively was 6.66 and a standard deviation of 2.399. The T value was calculated and was found to be 4.9321 and p value of 0.00001(p value less than 0.05 is significant. Similarly for the cases with active ulcer, the size assessment pre-operatively and post-SEPS was again analysed using student t test and the mean ulcer size prior to surgery was found to be 3.3 and standard deviation of 1.984. The T value was calculated and was found to be 1.789009 and a p value of 0.04 (p value less than 0.05 is significant. CONCLUSION Our study concluded that favourable and significant ulcer healing rate with improvement and reduction in clinical severity suggests that SEPS plays an important role in surgical management of advanced stages of venous insufficiency.

    Balloon expandable stents may on occasion be deployed in close proximity to the anchoring barbs of endovascular grafts. The aim of this study was to determine the risk and effect of balloon perforation by anchoring barbs and to assess whether these risks are different if the balloon is protected by a covered stent mounted upon it. A bench-top model was developed to mimic the penetration of anchoring barbs into the lumen of medium sized blood vessels. The model allowed variation of angle and depth of vessel penetration. Both bare balloons and those with covered stents mounted upon them were tested in the model to determine whether there was a risk of perforation and which factors increased or decreased this risk. All combinations of barb angle and depth caused balloon perforation but this was most marked when the barb was placed perpendicular to the long axis of the balloon. When the deployment of covered stents was attempted balloon perforation occurred in some cases but full stent deployment was achieved in all cases where the perforation was in the portion of the balloon covered by the stent. The only situation in which stent deployment failed was where the barb was intentionally placed in the uncovered portion of the balloon. This resulted in only partial deployment of the stent. Balloon rupture is a distinct possibility when deploying balloon-expandable stents in close proximity to anchoring barbs. Care should be taken in this circumstance to ensure that the barb is well away from the uncovered portion of the balloon. Copyright © 2012 European Society for Vascular Surgery.

    An experiment was conducted to determine the standardized ileal digestibility (SID) of CP and AA in brewers rice, full-fat rice bran (FFRB), defatted rice bran (DFRB), peanut meal, sesame meal, rapeseed meal, rapeseed expellers, soybean expellers, cassava meal, and bakery meal fed to young growing pigs. Twenty-two barrows (initial BW: 14.09 ± 1.48 kg) were surgically fitted with a T-cannula in the distal ileum and randomly allotted to a replicated 11 × 4 incomplete Latin square design with 11 diets and four 7-d periods in each square. Eleven experimental diets were prepared and test ingredients were the sole source of CP and AA in 10 diets and the eleventh diet was a N-free diet used to measure basal ileal endogenous losses of CP and AA. Chromic oxide (0.4%) was included in all diets as an indigestible marker and ileal digesta were collected on d 6 and 7 of each period. Results indicated that the SID of CP and AA was greatest (P < 0.05) in brewers rice and sesame meal and least (P < 0.05) in cassava meal. The SID of indispensable AA was greater (P < 0.05) in sesame meal compared with all other ingredients except brewers rice. Full-fat rice bran had greater (P < 0.05) SID of Arg, Ile, Leu, Lys, and Met compared with DFRB. The SID of CP and most AA was not different among rapeseed meal, rapeseed expellers, and soybean expellers. Bakery meal had the least (P < 0.05) SID of most AA compared with all other ingredients, with the exception of cassava meal. The concentration of standardized ileal digestible CP was greater (P < 0.05) in sesame meal and peanut meal (482.32 and 452.44 g/kg DM, respectively) than in all other ingredients. Soybean expellers had the greatest (P < 0.05) concentration of standardized ileal digestible Lys (22.98 g/kg DM) followed by rapeseed meal (16.11 g/kg DM) and rapeseed expellers (16.17 g/kg DM). Cassava meal and bakery meal had the least (P < 0.05) concentration of standardized ileal digestible CP and most AA compared with the other

    2018-01-01

    We perform a combined experimental and numerical investigation into the static deformation of perforated elastic strips under uniform aerodynamic loading at high-Reynolds-number conditions. The static shape of the porous strips, clamped either horizontally or vertically, is quantified as they are deformed by wind loading, induced by a horizontal flow. The experimental profiles are compared to numerical simulations using a reduced model that takes into account the normal drag force on the deformed surface. For both configurations (vertical and horizontal clamping), we compute the drag coefficient of the strip, by fitting the experimental data to the model, and find that it decreases as a function of porosity. Surprisingly, we find that, for every value of porosity, the drag coefficients for the horizontal configuration are larger than those of the vertical configuration. For all data in both configurations, with the exception of the continuous strip clamped vertically, a linear relation is found between the porosity and drag. Making use of this linearity, we can rescale the drag coefficient in a way that it becomes constant as a function of the Cauchy number, which relates the force due to fluid loading on the elastic strip to its bending rigidity, independently of the material properties and porosity of the strip and the flow speed. Our findings on flexible strips are contrasted to previous work on rigid perforated plates. These results highlight some open questions regarding the usage of reduced models to describe the deformation of flexible structures subjected to aerodynamic loading.

    Gastric non-Hodgkin lymphoma is a rare tumour that represents approximately 7% of all stomach cancers and 2% of all lymphomas. The most frequent location of gastric MALT (mucosa associated lymphoid tissue) lymphomas is in the antrum in 41% of the cases, and 33% can be multifocal. The risk of spontaneous perforation of a gastric MALT lymphoma is 4-10%. 24 year old male patient carrying the Human Immunodeficiency Virus, who began with signs and symptoms of acute abdomen and fever 72 hours before arriving in the emergency room. A computed tomography was performed that showed free fluid in the cavity, and gastric wall thickening. The patient underwent a laparotomy, finding absence of the anterior wall of the stomach, sealed with the left lobe of the liver, colon and omentum. Total gastrectomy, with oesophagosty and jejunostomy tube, was performed. Gastric perforation secondary to a MALT lymphoma is rare, with high mortality. There is limited information reported of this complication and should be highly suspected in order to provide appropriate treatment for a complication of this type.

    Acute pseudo-obstruction of the colon is a disorder characterised by an increase in intra-luminal pressure that leads to ischaemia and necrosis of the intestinal wall. The mechanism that produces the lesion is unknown, although it has been associated with: trauma, anaesthesia, or drugs that alter the autonomic nervous system. The pathophysiology of medication induced colon toxicity can progress to a perforated colon and potentially death. Present a case of a colonic pseudo-obstruction in a patient with polypharmacy as the only risk factor and to review the medical literature related to the treatment of this pathology. The case is presented of a 67 year old woman with colonic pseudo-obstruction who presented with diffuse abdominal pain and distension. The pain progressed and reached an intensity of 8/10, and was accompanied by fever and tachycardia. There was evidence of free intraperitoneal air in the radiological studies. The only risk factor was the use of multiple drugs. The colonic pseudo-obstruction progressed to intestinal perforation, requiring surgical treatment, which resolved the problem successfully. It is important to consider drug interaction in patients with multiple diseases, as it may develop complications that can be avoided if detected on time.

    This paper presents the results of the first part of a research program devised to develop and validate a CFD methodology to simulate the flow of water through perforated plates with geometry similar to the ones of the bottom end piece of a Pressurized Water Reactor. This component drives the coolant into the core, promotes an adequate mixing of dissolved substances and holds the fuel assembly mechanically. It accounts for a great part of the pressure loss through the core. The experimental pressure losses of water flow through 5 different perforated plates are presented here. The profile of the recovering of the pressure right downstream the plates was also measured. The experimental results were compared with numerical modeling performed with the commercial code CFX 10.0. Three different turbulence models of the two equation type were used in the simulations. The analysis of the results shows that the agreement between calculations and experiments decrease for flows with higher disturbance of the current. (author)

    In the future, surgical management of pediatric appendicitis might become limited to nonperforating appendicitis. Thus, it becomes increasingly important to differentiate advanced from simple appendicitis and to predict perforated appendicitis among a group of children with right-sided abdominal pain, which was the aim of this study. An institutionally approved, single-center retrospective analysis of all patients with appendectomy from January 2009 to December 2010 was conducted. All diagnostic aspects were evaluated to identify predictors and differentiators of perforated appendicitis. In 2 years, 157 children suffered from appendicitis. Perforation occurred in 47 (29.9%) of the patients. C-reactive protein (CRP) levels higher than 20 mg/dL ( P = .037) and free abdominal fluid on ultrasonography ( P = .031) are the most important features to differentiate perforated from simple appendicitis. Moreover, all children with perforation had a positive Heidelberg Appendicitis Score (HAS). A negative HAS excludes perforation in all cases (negative predictive value = 100%). Perforated appendicitis can be ruled out by the HAS. In a cohort with right-sided abdominal pain, perforation should be considered in children with high CRP levels and free fluids or abscess formation on ultrasound.

    2014-03-01

    Enhanced stimulation of the lower gut is hypothesized to play a key role in the weight loss and resolution of diabetes following bariatric surgeries. Ileal transposition (IT) permits study of the effects of direct lower gut stimulation on body weight, glucose homeostasis and other metabolic adaptations without the confounds of gastric restriction or foregut exclusion. However, the underlying mechanisms and the length of the ileum sufficient to produce metabolic benefits following IT surgery remain largely unknown. To determine the effects of transposing varying lengths of the ileum to upper jejunum on food intake, body weight, glucose tolerance and lower gut hormones, and the expression of key markers of glucose and lipid metabolism in skeletal muscle and adipose tissue in rats. Adult male Sprague-Dawley rats (n=9/group) were subjected to IT surgery with translocation of 5, 10 or 20 cm of the ileal segment to proximal jejunum or sham manipulations. Daily food intake and body weight were recorded, and an intraperitoneal glucose tolerance test was performed. Blood samples were assayed for hormones and tissue samples for mRNA (RT-qPCR) and/or protein abundance (immunoblotting) of regulatory metabolic markers. We demonstrate that IT surgery exerts ileal length-dependent effects on multiple parameters including: (1) decreased food intake and weight gain, (2) improved glucose tolerance, (3) increased tissue expression and plasma concentrations of glucagon-like peptide-1 (GLP-1) and peptide YY (PYY), and decreased leptin concentrations and (4) upregulation of key markers of glucose metabolism (glucose transporter-4 (GLUT-4), insulin receptor substrate 1 (IRS-1), adenosine monophosphate-activated protein kinase (AMPK), hexokinase (HK) and phosphofructokinase (PFK)) together with a downregulation of lipogenic markers (fatty acid synthase (FAS)) in muscle and adipose tissue. Together, our data demonstrate that the reduction in food intake and weight gain, increase in lower

    Full Text Available Esophageal perforation due to transesophageal echocardiogram (TEE during cardiac surgery is rare. A 72-year-old female underwent TEE during an operation for aortic valve replacement. Further, the patient presented hematemesis. Gastroscopy revealed an esophageal bleeding ulcer. Endoscopic therapy was successful. Although a CT scan excluded perforation, the patient became febrile, and a second gastroscopy revealed a big perforation at the site of ulcer. The patient's clinical condition required endoscopic intervention with a new OTSC® clip (Ovesco Endoscopy, Tübingen, Germany. The perforation was successfully sealed. The patient remained on intravenous antibiotics, proton pump inhibitors and parenteral nutrition for few days, followed by enteral feeding. She was discharged fully recovered 3 months later. We clearly demonstrate an effective, less invasive treatment of an esophageal perforation with a new endoscopic clip.

  20. Delayed colonic perforation following stent placement for colorectal obstruction: a description of two cases with stent palliation.

    Directory of Open Access Journals (Sweden)

    Jalal Vahedian Ardakani

    2013-10-01

    Full Text Available Bowel stent insertion has a variety of complications one major of which is colonic perforation. The purpose of this article is to reveal two cases with delayed colonic perforation after stent placement to relieve bowel obstruction caused by rectal cancer. The first patient was a 55 year-old man who was a candidate for stent placement to avoid palliative surgery and relieve his bowel obstruction. Although the procedure resulted in complete relief of patient symptoms, but he returned with signs of peritonitis 10 days after the stent placement. A perforation was found at rectosigmoid junction on laparotomy. The second patient was a 60 year-old man who underwent a successful stent placement and returned 3 months later with a complaint of abdominal pain that showed up to be due to a rectal perforation on investigations. In conclusion, bowel perforation following stent placement can be a major complication, so close follow-up is necessary to detect it as soon as possible and prevent it from becoming an irreparable complication.

  1. Enhancement of acetylcholine-induced desensitization of guinea-pig ileal longitudinal muscle in Ca2+-free conditions.

    1. To determine the role of cellular Ca2+ in desensitization, acetylcholine(ACh)-induced desensitization was studied under Ca2+-free condition in guinea-pig ileal longitudinal muscle. 2. Pretreatment of the tissue with 10(-4) M ACh (desensitizing treatment) in normal Tyrode solution caused desensitization of the responses both to ACh and histamine. The desensitizing treatment performed in Ca2+-free solution enhanced desensitization of the responses to ACh and histamine significantly. 3. The desensitizing treatment with ACh caused suppression of the responses to high K+ (tonic component) and Bay K 8644. The desensitizing treatment performed in Ca2+-free solution potentiated the suppression of the responses to high K+ and Bay K 8644 significantly. 4. ACh-induced desensitization was enhanced significantly in the presence of a protein kinase C inhibitor, 1-(5-isoquinolinesulfonyl)-2-methylpiperazine(H-7, 10(-4) M) to a similar extent as desensitization obtained under Ca2+-free condition, but not in the presence of a non-specific and less potent kinase inhibitor, N-(2-guanidinoethyl)-5-isoquinolinesulfonamide hydrochloride (HA1004, 10(-4) M). 5. These results suggested that voltage-gated Ca2+ channels were involved in ACh-induced desensitization and that intracellular Ca2+, which was increased during the stimulation with ACh, inhibited desensitization through the activation of protein kinase C. This kinase could have activated or protected Ca2+ channels during the desensitization process to reduce desensitization.

Sacrocolpopexy during cystectomy with orthotopic ileal bladder is a valuable surgical method which provides patients with a better quality of life.

  6. How I do it: the stapled ileal J pouch at restorative proctocolectomy.

    LENUS (Irish Health Repository)

    Martin, S T

    2011-12-01

    Ileal pouch-anal anastomosis (IPAA) following proctocolectomy is the preferred option for patients with medically refractory ulcerative colitis, indeterminate colitis, and familial adenomatous polyposis. However, it remains a procedure associated with morbidity and mortality. Pelvic sepsis, pouch fistulae, and anastomotic dehiscence predispose to pouch failure. We report our experience with an adaptation for the formation of the stapled ileal J pouch using the GIA™ 100 stapling device (Covidien, Mansfield, Massachusetts, USA). When creating the J pouch, we remove the bevelled plastic protector from the thin fork of the stapling device, allowing the staple line to be completed to the tip of the stapled efferent limb of the pouch, thereby minimizing potential blind ending in the efferent limb and injury to the transverse staple line.

  7. Determinants of Hearing Loss in Perforations of the Tympanic Membrane

    Mehta, Ritvik P.; Rosowski, John J.; Voss, Susan E.; O’Neil, Ellen; Merchant, Saumil N.

    2010-01-01

    Background Although tympanic membrane perforations are common, there have been few systematic studies of the structural features determining the magnitude of the resulting conductive hearing loss. Our recent experimental and modeling studies predicted that the conductive hearing loss will increase with increasing perforation size, be independent of perforation location (contrary to popular otologic belief), and increase with decreasing size of the middle-ear and mastoid air space (an idea new to otology). Objective To test our predictions regarding determinants of conductive hearing loss in tympanic membrane perforations against clinical data gathered from patients. Study Design Prospective clinical study. Setting Tertiary referral center. Inclusion Criteria Patients with tympanic membrane perforations without other middle-ear disease. Main Outcome Measures Size and location of perforation; air-bone gap at 250, 500, 1,000, 2,000, and 4,000 Hz; and tympanometric estimate of volume of the middle-ear air spaces. Results Isolated tympanic membrane perforations in 62 ears from 56 patients met inclusion criteria. Air-bone gaps were largest at the lower frequencies and decreased as frequency increased. Air-bone gaps increased with perforation size at each frequency. Ears with small middle-ear volumes, ≤4.3 ml (n = 23), had significantly larger air-bone gaps than ears with large middle-ear volumes, >4.3 ml (n = 39), except at 2,000 Hz. The mean air-bone gaps in ears with small volumes were 10 to 20 dB larger than in ears with large volumes. Perforations in anterior versus posterior quadrants showed no significant differences in air-bone gaps at any frequency, although anterior perforations had, on average, air-bone gaps that were smaller by 1 to 8 dB at lower frequencies. Conclusion The conductive hearing loss resulting from a tympanic membrane perforation is frequency-dependent, with the largest losses occurring at the lowest sound frequencies; increases as size of the

    Pedicled superior epigastric artery perforator (SEAP) flaps can be raised to cover challenging thoracic defects. We present an anatomical study based on multidetector computerized tomography (MDCT) scan findings of the SEA perforators in addition to the first reported clinical series of SEAP flaps in anterior chest wall reconstruction. (a) In the CT scan study, images of a group of 20 patients who underwent MDCT scan analysis were used to visualise bilaterally the location of musculocutaneous SEAP. X- and Y-axes were used as landmarks to localise the perforators. The X-axis is a horizontal line at the junction of sternum and xyphoid (JCX) and the Y-axis is at the midline. (b) In the clinical study, seven pedicled SEAP flaps were performed in another group of patients. MDCT images revealed totally 157 perforators with a mean of 7.85 perforators per patient. The dominant perforators (137 perforators) were mainly localised in an area between 1.5 and 6.5 cm from the X-axis on both sides and between 3 and 16 cm below the Y-axis. The calibre of these dominant perforators was judged as 'good' to 'very good' in 82.5% of the cases. The average dimension of the flap was 21.7x6.7 cm. All flaps were based on one perforator. Mean harvesting time was 110 min. There were no flap losses. Minor tip necrosis occurred in two flaps. One of them was treated with excision and primary closure. Our clinical experience indicates that the SEAP flap provides a novel and useful approach for reconstruction of anterior chest wall defects. CT-based imaging allows for anatomical assessment of the perforators of the superior epigastric artery (SEA).

    Background: The gold standard of the management of rectal cancer in the middle and lower parts is low anterior resection with coloanal anastomosis. About 50% of the patients undergoing this procedure might experience some complications because of the low capacity of the neorectum. The aim of this study was to evaluate ileal J-pouch interposition as a neorectum between the anal canal and the remaining colon in comparison to coloanal anastomosis and transverse coloplasty. Methods: Twelve dogs, weighing 23-27 kg, were divided into three groups. After laparotomy, the volume of the primary rectum was measured so that it could be compared with that of the neorectum at the end of the study. After rectal resection in Group A, the colon was directly anastomosed to the anus. In Group B, a 5-cm longitudinal incision was made 2 cm proximal to the anastomosis and was sutured transversely (coloplasty). In Group C, a 5-cm ileal J-pouch was interposed between the colon and anus. After 8 weeks, the neorectum was evaluated for volume, radiology, and pathology. Results: All the samples were alive until the end of the study. The healing of the anastomotic lines was acceptable (pathologically) in all. The mean volume expansion was 20.9% in Group A, 21.7% in Group B, and 118.2% in Group C, with the latter being significantly higher than that of the other groups (P=0.03). Colon J-pouch and coloplasty after proctectomy in some situations have not been performable. This study evaluated the performance of ileal J-pouch interposition. Conclusion: This study showed that ileal J-pouch interposition might produce an acceptable reservoir function and that it seems feasible and safe in selected cases. PMID:24644380

As early improvement of glicaemic control is observed after bariatric surgeries, there is currently a search for surgical procedures that can promote euglycemia also in non-obese patients. Glicaemic control can be achieved by increasing the blood concentration of GLP-1, a hormone produced by L cells that are more densely concentrated in the terminal ileum.

    The extent of preoperative small-bowel mucosal inflammation may be an important predictor of pouchitis after ileal pouch-anal anastomosis. This study examined the value of preoperative wireless capsule endoscopy in predicting outcome of ileal pouch-anal anastomosis in patients with ulcerative colitis or indeterminate colitis. Patients undergoing complete wireless capsule endoscopy before ileal pouch-anal anastomosis were identified. Findings on wireless capsule endoscopy were classified as positive (erosions, ulcers or erythema) or negative. Outcome was assessed prospectively and included no pouchitis, acute pouchitis, chronic pouchitis, or de novo Crohn disease. Patients with acute pouchitis, chronic pouchitis, or de novo Crohn disease were considered to have pouch inflammation. The 68 study patients (48 ulcerative colitis; 20 indeterminate colitis) had a median age of 38 years and included 34 males. Median follow-up time after ileostomy closure was 12 months (range, 3-63 months). Wireless capsule endoscopy was positive in 15 patients (22%) and negative in 53 patients (78%). Pouch inflammation was observed in 23 patients (34%), and included 8 patients with acute pouchitis, 3 patients with chronic pouchitis, and 12 patients with de novo Crohn disease. The incidence of acute pouchitis, chronic pouchitis, de novo Crohn disease, and pouch inflammation in the wireless capsule endoscopy-positive patient group was 7%, 7%, 20%, and 33% compared with 13%, 4%, 17%, and 34% in the wireless capsule endoscopy-negative patient group (all P = NS). There was no statistical association between the results of preoperative wireless capsule endoscopy and outcome after ileal pouch-anal anastomosis in patients with ulcerative colitis or indeterminate colitis. There seems to be little value of wireless capsule endoscopy in the preoperative evaluation of these patients.

    Full Text Available The objective of this experiment was to determine the concentration and digestibility of crude protein (CP and amino acid (AA in meat meal (MM, and to compare these values with the respective values in soybean meal (SBM. Six barrows (initial body weight = 66.9±3.8 kg surgically fitted with a T-cannula at the distal ileum were allotted to a replicated 3×3 balanced Latin square design with 3 diets and 3 periods. Two experimental diets containing test ingredients as the sole source of AA were prepared to estimate the apparent ileal digestibility (AID for CP and AA by the direct method. An N-free diet was also prepared to estimate basal endogenous losses of CP and AA. All experimental diets contained 5% chromic oxide as an indigestible index. Each period consisted of a 5-d adaptation period and a 2-d of ileal digesta collection period. Ileal digesta samples were collected from 0900 to 1700 on d 6 and 7 of each period. The concentrations of CP, Lys, Met, and Trp in MM and SBM were analyzed to be 64.1, 3.5, 1.1 and 0.6, and 45.6, 2.8, 0.8, and 0.3%, respectively. The AID of all AA except Gly in MM was less (p<0.05 than in SBM. The AID of Lys, Met, and Trp in MM was estimated to be 56.0, 71.7, and 47.1%, respectively. The SID of all AA in MM was less (p<0.05 than in SBM. The SID of Lys, Met, and Trp was 65.1, 79.2, and 78.5%, respectively. In conclusion, the CP and AA contents in MM were greater than those in SBM whereas the ileal digestibility of all AA in MM was less than in SBM.

    Full Text Available Introduction. Bochdalek hernia is a congenital defect of the diaphragm that is usually diagnosed in the neonatal period and incidentally in asymptomatic adults. Small bowel incarceration in a right-sided Bochdalek hernia is exceptional for an adult. Case Presentation. A 54-year-old woman was admitted for acute dyspnea, tachycardia, hypotension, and fever. Five days before, she had been experiencing an episode of diffuse abdominal pain. The admission chest X-ray was interpreted as right pleural effusion and pneumothorax with left mediastinal shift. Chest tube drainage was purulent. The thoracoabdominal CT examination suspected an intestinal incarceration through a right diaphragmatic defect. At laparotomy, a right-sided Bochdalek hernia was confirmed with a complete necrosis of the incarcerated caecum. Ileocaecal resection was performed, but the patient died from delayed septic complications. Conclusion. Intrathoracic perforation of the caecum is a rare occurrence; delayed diagnosis due to misleading initial symptoms may lead to severe complications and poor prognosis.

    Full Text Available A 45 year old Caucasian man with a history of HIV/AIDS was admitted for septic shock secondary to right lower lobe community acquired pneumonia. The patient’s respiratory status continued to decline requiring emergency intubation in a non-ICU setting. Four laryngoscope intubation attempts were made including an inadvertent esophageal intubation. Subsequent CT imaging revealed a tracheal defect (Figure 1, red arrow with communication to the mediastinum and air around the trachea consistent with pneumomediastinum (Figure 2, orange arrow and figure 3, yellow arrow. Pneumopericardium (figure 4, blue arrow was also evident post-intubation. The patient’s hemodynamic status remained stable. Two days following respiratory intubation subsequent chest imaging revealed resolution of the pneumomediastinum and pneumopericardium and patient continued to do well without hemodynamic compromise or presence of subcutaneous emphysema. Post-intubation tracheal perforation is a rare complication of traumatic intubation and may be managed with surgical intervention or conservative treatment (1.

    Full Text Available History of present illness: A 51-year-old male presents complaining of increasing right groin pain and an enlarging bulge. Symptoms started as a “bubble” 6 weeks prior to presentation. One week prior to presentation, thinking the bulge was an abscess, the patient attempted to “pop” the bulge with a sewing needle, the needle became lodged in the site and he attempted retrieval with a second sewing needle, which also became lodged. No purulent material was obtained. The patient denied any nausea, vomiting or constipation as well as any fevers or urinary symptoms. His abdomen was soft, non-tender, non-distended with active bowel sounds. The groin exam demonstrated an incarcerated right inguinal hernia and cellulitis of the right hemiscrotum with associated induration and tenderness. Significant findings: The AP and lateral pelvis x-rays revealed two sewing needles, 60 mm in length, within the soft tissue over the anterior right lower hemipelvis. In addition, the AP view showed emphysema involving the right hemiscrotum (arrow, concerning for perforated bowel. Discussion: Groin hernias have a lifetime risk of 27% for men and 3% for women and the incidence increases with age.1 Groin hernias can be either direct or indirect, and inguinal or femoral. The distinction is made during surgery. Femoral hernias make up only 5% of groin hernias but are more common in women.1 Concerning complications include incarceration, in which a hernia cannot be reduced, and strangulation in which vascular compromise occurs.1 Incarcerated hernias often present with a painful, tender mass and are difficult to distinguish from strangulation. Patients with strangulation may present with fevers and peritonitis. The overlying skin may also be red.2 The percentage of patients presenting with strangulation varies by region. Western developed countries report only 1%-3% of patients presenting as surgical emergencies whereas in Africa the percentage can be as high as 26

  18. The Bloch Approximation in Periodically Perforated Media

    2005-01-01

    We consider a periodically heterogeneous and perforated medium filling an open domain Ω of R N . Assuming that the size of the periodicity of the structure and of the holes is O(ε),we study the asymptotic behavior, as ε → 0, of the solution of an elliptic boundary value problem with strongly oscillating coefficients posed in Ω ε (Ω ε being Ω minus the holes) with a Neumann condition on the boundary of the holes. We use Bloch wave decomposition to introduce an approximation of the solution in the energy norm which can be computed from the homogenized solution and the first Bloch eigenfunction. We first consider the case where Ωis R N and then localize the problem for abounded domain Ω, considering a homogeneous Dirichlet condition on the boundary of Ω

  19. Synaptotoxicity of Alzheimer beta amyloid can be explained by its membrane perforating property.

    Directory of Open Access Journals (Sweden)

    Fernando J Sepulveda

    Full Text Available The mechanisms that induce Alzheimer's disease (AD are largely unknown thereby deterring the development of disease-modifying therapies. One working hypothesis of AD is that Abeta excess disrupts membranes causing pore formation leading to alterations in ionic homeostasis. However, it is largely unknown if this also occurs in native brain neuronal membranes. Here we show that similar to other pore forming toxins, Abeta induces perforation of neuronal membranes causing an increase in membrane conductance, intracellular calcium and ethidium bromide influx. These data reveal that the target of Abeta is not another membrane protein, but that Abeta itself is the cellular target thereby explaining the failure of current therapies to interfere with the course of AD. We propose that this novel effect of Abeta could be useful for the discovery of anti AD drugs capable of blocking these "Abeta perforates". In addition, we demonstrate that peptides that block Abeta neurotoxicity also slow or prevent the membrane-perforating action of Abeta.

  20. Visible Perforating Lateral Osteotomy: Internal Perforating Technique with Wide Periosteal Dissection

    2016-01-01

    There are two general categories of lateral osteotomy techniques—the external perforating method and the internal continuous method. Regardless of which technique is used, procedural effectiveness is hampered by limited visualization in the surgical field. Considering this point, we devised a new technique that involves using a wide subperiosteal dissection and internal perforation under direct visualization. Using an intranasal approach, whereby the visibility of the intended fracture line was maintained, enabled a greater degree of control, and in turn, results that were more precise, and thus predictable and reproducible. Traditionally, it has been taken as dogma that the periosteum must be preserved, considering the potential for dead space and bony instability; however, under sufficient visualization of the surgical field with an internal perforating method, complete osteotomy with fully preserved intranasal mucosa could be conducted exactly as intended. This intact mucosal lining compensates for the elevated periosteum. Compressive dressing and drainage through a Silastic angio-needle catheter enabled the elimination of dead space. Therefore, precise, reproducible, and predictable osteotomy minimizing the potential for associated complications such as ecchymosis, that is, bruising owing to hemorrhage, could be performed. In this article, we introduce a novel technique for lateral osteotomy with improved visualization. PMID:26848452

    The objective was to define the Val requirement for weaned piglets in the context of reducing the dietary protein content. A dose-response experiment was conducted to estimate the standardized ileal digestible (SID) Val to Lys ratio required to support the optimum growth of post-weaned piglets. In this study, 96 pigs weighing 8 kg were allotted to one of six dietary treatments (16 pigs for each dietary treatment) and were housed individually. Diets were formulated to provide 0.58, 0.62, 0.66, 0.70, 0.74 and 0.78 SID Val : Lys by adding graded levels of crystalline l-Val to the 0.58 SID Val : Lys diet. Lysine was sub-limiting and supplied 90% of the recommendation (10.95 g SID Lys/kg equal to 11.8 g/kg total Lys). Average daily feed intake (ADFI), average daily gain (ADG) and gain to feed ratio (G : F) were determined during a 14-day period of ad libitum feeding. Blood and urine samples were taken at the end of each week (day 7 and 14 of the experiment) 3 h after feeding the experimental diets. The maximum ADFI and ADG were obtained in pigs fed the 0.78 SID Val : Lys diet; it was not different from the results of pigs fed 0.70 SID Val : Lys diet. The highest G : F was obtained in pigs fed 0.70 SID Val : Lys. The plasma concentration of Val increased linearly (Pratio was affected by treatment. The minimum SID Val : Lys required to maximize ADFI, ADG and G : F was estimated at 0.67 SID Val : Lys by a broken-line model, and at 0.71 SID Val : Lys by a curvilinear plateau model. The Val deficiency caused a reduction in ADFI, and Val supplementation above the requirement did not impair animal performance. In conclusion, 0.70 SID Val : Lys is suggested as the Val requirement for 8 to 14 kg individually housed pigs.

    Full Text Available Aim: Combination of laparoscopic ileal interposition (II with sleeve gastrectomy (SG is an upcoming procedure, which offers good metabolic improvement and weight reduction without causing significant malabsorption. The objective of this study was to evaluate the results of this novel procedure for control of type 2 diabetes, obesity, hypertension, and related metabolic abnormalities. Materials and Methods: The II and SG was performed in 43 patients (M:F = 25:18 from February 2008. Participants had a mean age of 47.2 ± 8.2 years (range 29-66 years, mean duration of diabetes of 10.1 ± 9.2 years (range 1-32 years, and mean preoperative body mass index (BMI of 33.2 ± 7.8 kg/m2. All patients had poorly controlled type 2 diabetes mellitus (DM [mean glycated hemoglobin (HbA1C 9.6 ± 2.1%] despite use of oral hypoglycemic agents (OHAs and/or insulin. Thirty (70% patients had hypertension, 20 (46% had dyslipidemia, and 18 (42% had significant microalbuminuria. The primary outcome was remission of diabetes (HbA1C < 6.5% without OHAs/insulin and the secondary outcomes were reduction in antidiabetic agent requirement and components of metabolic syndrome. Results: Mean follow-up was for 20.2 ± 8.6 months (range 4-40 months. Postoperatively, glycemic parameters (fasting and post-lunch blood sugar, HbA1C improved in all patients (P < 0.05 at all intervals. Twenty (47% patients had remission in diabetes and the remaining patients showed significantly decreased OHA requirement. All patients had weight loss between 15 and 30% (P < 0.05. Twenty-seven (90% patients had remission in hypertension. At 3 years, the mean fall in HbA1C (34% was more than reduction in BMI (25%. There was a declining trend in lipids and microalbuminuria postoperatively, though it was significant for microalbuminuria only. Conclusions: The laparoscopic II with SG seems to be a promising procedure for control of type 2 DM, hypertension, weight reduction, and associated metabolic

    Full Text Available Retinal detachment after ocular perforation related to local anesthesia is a common complication, which is usually associated with a poor prognosis despite complex vitreoretinal surgical procedures. We report a case of 62-year-old male with cataract surgery done 4 weeks back with nasal retinal detachment with a posterior break. Pneumatic retinopexy was performed and laser barrage of the breaks was done the next day when the retina got attached. A vision of 20/30 was achieved at the end of 2 months. To the best of our knowledge, this is a first case report in literature where pneumatic retinopexy was used to manage a retinal detachment caused by block-related perforation.

    Full Text Available Pneumomediastinum, and subcutaneous emphysema usually result from spontaneous alveolar wall rupture and, far less commonly, from disruption of the upper airways or gastrointestinal tract. Subcutaneous neck emphysema, pneumomediastinum, and retropneumoperitoneum caused by nontraumatic perforations of the colon have been infrequently reported. The main symptoms of spontaneous subcutaneous emphysema are swelling and crepitus over the involved site; further clinical findings in case of subcutaneous cervical and mediastinal emphysema can be neck and chest pain and dyspnea. Radiological imaging plays an important role to achieve the correct diagnosis and extension of the disease. We present a quite rare case of spontaneous subcutaneous cervical emphysema, pneumomediastinum, and pneumoretroperitoneum due to perforation of an occult sigmoid diverticulum. Abdomen ultrasound, chest X-rays, and computer tomography (CT were performed to evaluate the free gas extension and to identify potential sources of extravasating gas. Radiological diagnosis was confirmed by the subsequent surgical exploration.

    Full Text Available Patients with autosomal dominant polycystic kidney disease (ADPKD usually have extrarenal manifestations. We report the case of a 53-year-old man with ADPKD who presented with a retroperitoneal abscess of the left side after undergoing bilateral nephrectomy for a cyst that had repeatedly bled for 1 year. The abscess recurred despite drainage with a pig-tail catheter and antibiotic treatment. Fistulography with injection of diluted contrast medium via the pig-tail catheter showed an accumulation of contrast medium in the descending colon, which indicated a fistula between the abscess and the descending colon. A portion of the descending colon was resected, and multiple diverticulitis with 1 perforation in the resected specimen was observed. The findings support a diagnosis of retroperitoneal abscess caused by a perforated diverticulum—an extrarenal manifestation of ADPKD.

    Abstract Fournier gangrene is a necrotizing soft tissue infection involving the perineum. We present a case of Fournier gangrene as the clinical presentation of perforated metastatic rectal cancer. The patient is a 78-year-old man in a nursing home who presented to our institution with necrosis and ischemia of the scrotum. After wide debridement of necrotic tissue and bilateral orchiectomy, computed tomography was carried out to investigate abnormal findings seen on his chest X-ray, which revealed multiple pulmonary metastases as well as a mass highly suspicious for a perforated rectal mass. Once stable, a diverting colostomy and biopsies of the rectal mass were performed, confirming the presence of a metastatic, poorly differentiated rectal adenocarcinoma. Albeit an unusual etiology of Fournier gangrene, this case highlights the rare but important causes of this deadly condition and teaches us to be cognizant of the variations in the presentation of colorectal cancer.

    Diarrhea incidence in weaned pigs may be associated with the concentration of intestinal microbial metabolites (ammonia, amines, and VFA) that are influenced by dietary CP content. Three experiments were conducted to determine effects of a low-protein, AA-supplemented diet on ileal AA digestibility, growth performance, diarrhea incidence, and concentration of microbial metabolites in ileal and cecal digesta of pigs weaned at 14 d of age. In Exp. 1, 8 pigs fitted with a simple T-cannula at the distal ileum were assigned in a crossover design to 2 diets containing 24 or 20% CP using wheat, corn, full-fat soybeans, whey powder, fish meal, and blood plasma as the main ingredients. Supplemental AA were added to the diets to meet the AA standards according to the 1998 NRC recommendations. Chromic oxide was used as an indigestible marker. Diets were fed at 2.5 times the ME requirement for maintenance. The reduction of dietary CP decreased (P water. Dietary CP content did not affect growth performance or fecal consistency scores during the 3-wk study, and diarrhea was not observed. The results of these experiments indicate that lowering the dietary CP content combined with supplementation of AA markedly reduced the production of potentially harmful microbial metabolites in cecal digesta of early-weaned pigs without affecting growth performance.

    2013-10-01

    Full Text Available Coconut oil premixed combustion behavior has been studied experimentally on perforated burner with equivalence ratio (φ varied from very lean until very rich. The results showed that burning of glycerol needs large number of air so that the laminar burning velocity (SL is the highest at very lean mixture and the flame is in the form of individual Bunsen flame on each of the perforated plate hole. As φ is increased the  SL decreases and the secondary Bunsen flame with open tip occurs from φ =0.54 at the downstream of perforated flame. The perforated flame disappears at φ = 0.66 while the secondary Bunsen flame still exist with SL increases following that of hexadecane flame trend and then extinct when the equivalence ratio reaches one or more. Surrounding ambient air intervention makes SL decreases, shifts lower flammability limit into richer mixture, and performs triple and cellular flames. The glycerol diffusion flame radiation burned fatty acids that perform cellular islands on perforated hole.  Without glycerol, laminar flame velocity becomes higher and more stable as perforated flame at higher φ. At rich mixture the Bunsen flame becomes unstable and performs petal cellular around the cone flame front. Keywords: cellular flame; glycerol; perforated flame;secondary Bunsen flame with open tip; triple flame

    Full Text Available Objective: The purpose of this study was to investigate the histological response to delib-erate perforation repaired using amalgam or MTA either immediately or with delay on cats’ molars.Materials and Methods: Twenty-eight molar teeth from four cats were used in this ex-perimental randomized study. After preparing the access cavity, the floor of pulp cham-bers were deliberately perforated with a round bur No. 5. The teeth were randomly divided into four groups of seven. In groups one and two,the perforation was immediately sealed with amalgam and MTA, respectively. In groups three and four, the perforations were leftexposed to saliva for six weeks and then sealed with amalgam or MTA. The animals were sacrificed four months later and the specimens processed. The samples were blindly exam-ined for inflammatory reaction and healing process under light microscope. The data were analyzed with Mann-Whitney U and Fisher exact tests.Results: The type of the materials used has no significant effect on the severity of in-flammation; while, immediate or delayed repair of furcal perforation has, and immediate application of, MTA produced less inflammation than that of amalgam (P<0.05. No dif-ferences were found in vasodilatation, abscess formation or healing process between the immediate and the delayed repair groups (P=0.13.Conclusion: MTA is a more suitable material than amalgam for perforation repair, par-ticularly when used immediately after perforation.

    Oral and maxillofacial surgery, which involves several sharp instruments and fixation materials, is consistently at a high risk for cross-contamination due to perforated gloves, but it is unclear how often such perforations occur. This study aimed to address this issue. The frequency of the perforation of surgical gloves (n=1436) in 150 oral and maxillofacial surgeries including orthognathic surgery (n=45) was assessed by the hydroinsufflation technique. Orthognathic surgery had the highest perforation rate in at least 1 glove in 1 operation (91.1%), followed by cleft lip and palate surgery (55.0%), excision of oral soft tumour (54.5%) and dental implantation (50.0%). The perforation rate in scrub nurses was 63.4%, followed by 44.4% in surgeons and first assistants, and 16.3% in second assistants. The odds ratio for the perforation rate in orthognathic surgery versus other surgeries was 16.0 (95% confidence interval: 5.3-48.0). The protection rate offered by double gloving in orthognathic surgery was 95.2%. These results suggest that, regardless of the surgical duration and blood loss in all fields of surgery, orthognathic surgery must be categorized in the highest risk group for glove perforation, following gynaecological and open lung surgery, due to the involvement of sharp objects.

    Accidental root canal perforations are among the main complications of endodontic treatment. This study evaluated the influence of operating microscope (OM) in the marginal adaptation of mineral trioxide aggregate (MTA) (Angelus(®)) and glass ionomer (Vitremer) inserted into cervical perforations. Perforations were made in the cervical third of the buccal wall of the root canal in mandibular incisors. Next, the teeth were divided into four groups (N = 10): MG - MTA without OM; VG - Vitremer without OM; MOMG - MTA with OM; VOMG - Vitremer with OM. The perforations were sealed according to the group and the teeth were prepared for analysis by confocal laser scanning microscope. Images of perforation region (1,024×) were made and the gap presented by the materials was measured using the Image J program. LEXT OLS4100 three dimensional (3D) measuring laser microscope measured the volumetric misfit. Data of gap were analyzed by Kruskal-Wallis and Dunn's tests. Analysis of variance (ANOVA) and Tukey's tests compared the volumetric misfits. The results showed lower volume and gap in the interface dentin/material in VOMG compared to the other groups (P < 0.05). The use of OM improved the quality of cervical perforations sealed with Vitremer, being indicated in clinical situations of iatrogenic cervical perforations.

    Full Text Available The thermal performance of three solar collectors with 3, 6 mm and without perforation absorber plate was assessed experimentally. The experimental tests were implemented in Baghdad during the January and February 2017. Five values of airflow rates range between 0.01 – 0.1 m3/s were used through the test with a constant airflow rate during the test day. The variation of the following parameters air temperature difference, useful energy, absorber plate temperature, and collector efficiency was recorded every 15 minutes. The experimental data reports that the increases the number of absorber plate perforations with a small diameter is more efficient rather than increasing the hole diameter of the absorber plate with decreasing the perforation numbers. Maximum air temperature difference throughout the solar collector with 3, 6 mm perforations and without perforations are 17, 15, and 12 oC, respectively. Also, it can be concluded that the energy gained from the solar collector with 3 mm perforation absorber plate is 28.2 % more than the energy gained from solar collector without holes per day for 0.1 m3/s airflow rate. The maximum values of the thermal performance curves are 0.67, 0.64, and 0.56 for the solar collector with 3, 6 mm, and without perforations, respectively.

    The treatment of perforated foregut ulcers by omental patching (OP) or primary closure has mostly replaced vagotomy and pyloroplasty/antrectomy (VPA). We sought to determine the natural history and recurrence rate of ulceration in patients treated by omental patching or primary closure. An 11-year retrospective study. From 2004 through 2015, 94 patients had perforated foregut ulcers, 53 gastric, and 41 duodenal. 77 (82%) were treated by OP alone (study group) and 17 (18%) were treated with VPA (comparison group). All OP patients were discharged on PPIs, but only 86% took the drugs for a median of 22 months (1-192, SD 40). Endoscopy in the OP group showed recurrent ulcers in nine (12% recurrence rate) and gastritis in three (4%) This group also had three later recurrent perforations. Another recurrent ulcer hemorrhaged causing death (3% late mortality). Two other patients required non-emergent re-do ulcer operations for recurrent disease/symptoms (surgical re-intervention rate 4%). Total length of follow-up was median 44 months (1-192, SD 40) and was complete in 82 (87%). 18 (23%) patients in the OP group developed recurrent abdominal pain attributed to ulcer disease during follow-up, compared to 2 (12%) in the VPA group (p = 0.15). No patient in the VPA group had an endoscopic recurrence or re-intervention. Omental patching does not correct the underlying disease process which causes foregut perforation, and has a 12% endoscopically proven recurrent ulceration rate and a 23% incidence of recurrent symptoms within 44 months. Patients tend to stop taking PPIs after 22 months at which time their risk increases.

    Full Text Available Background: Dermatomyositis (DM is an autoimmune disease characterized by cutaneous Gottron papules, heliotrope rash, and proximal myopathy. It may also present as a paraneoplastic syndrome that can complicate a variety of different cancers, such as lung, cervical, and breast cancer. However, the association with hepatocellular carcinoma (HCC is extremely rare. Moreover, to our knowledge, there are no previous reports of colonic perforation following steroid pulse treatment for a DM patient. Case Summary: A 61-year-old male complained of a skin rash that began in his neck and spread to his face and abdomen. On physical examination, the patient was also found to have symmetrical proximal muscle weakness, abdominal pain, heliotrope rash in the periorbital skin, and poikiloderma on his face and abdomen. Serum level of muscle enzymes was remarkably increased. Muscle examination revealed symmetrical proximal weakness. The diagnosis of DM was made, and steroid treatment was started for symptomatic relief. A search for causative malignancy revealed HCC. Despite steroid therapy for DM, his symptoms did not improve. Additionally, C-reactive protein elevation was seen along with severe abdominal pain on day 14 of admission. Shortly after this, the patient died of septic shock due to suppurative peritonitis after perforation of the ascending colon. Conclusion: Here, we present a rare case of DM caused by non-hepatitis-associated advanced HCC with colonic perforation. The cause of colonic perforation is still unclear. This case demonstrates the need to carefully monitor abdominal pain in DM patients as symptoms can be masked by steroid therapy.

    The cerebellopontine angle is a common site for tumor growth and vascular pathologies requiring surgical manipulations that jeopardize cranial nerve integrity and cerebellar and brainstem perfusion. To date, a detailed study of vessels perforating the cisternal surface of the middle cerebellar peduncle-namely, the paraflocculus or parafloccular perforating space-has yet to be published. In this report, the perforating vessels of the anterior inferior cerebellar artery (AICA) in the parafloccular space, or on the cisternal surface of the middle cerebellar peduncle, are described to elucidate their relevance pertaining to microsurgery and the different pathologies that occur at the cerebellopontine angle. Fourteen cadaveric cerebellopontine cisterns (CPCs) were studied. Anatomical dissections and analysis of the perforating arteries of the AICA and posterior inferior cerebellar artery at the parafloccular space were recorded using direct visualization by surgical microscope, optical histology, and scanning electron microscope. A comprehensive review of the English-language and Spanish-language literature was also performed, and findings related to anatomy, histology, physiology, neurology, neuroradiology, microsurgery, and endovascular surgery pertaining to the cerebellar flocculus or parafloccular spaces are summarized. A total of 298 perforating arteries were found in the dissected specimens, with a minimum of 15 to a maximum of 26 vessels per parafloccular perforating space. The average outer diameter of the cisternal portion of the perforating arteries was 0.11 ± 0.042 mm (mean ± SD) and the average length was 2.84 ± 1.2 mm. Detailed schematics and the surgical anatomy of the perforating vessels at the CPC and their clinical relevance are reported. The parafloccular space is a key entry point for many perforating vessels toward the middle cerebellar peduncle and lateral brainstem, and it must be respected and protected during surgical approaches to the

    To report the case of a patient with keratoconus who developed a corneal perforation secondary to UV radiation from a tanning lamp. We believe this to be the first case of a corneal perforation secondary to UV radiation. The presentation and management of the patient and the pathophysiology of UV keratitis are discussed. Our patient developed a full-thickness corneal perforation after 30 minutes of tanning lamp exposure without eye protection. The cornea was temporized with cyanoacrylate tissue adhesive until penetrating keratoplasty could be performed. With an increased understanding of the pathophysiology of UV damage, treatment should be aimed at modulating the disease to reduce the likelihood of a poor outcome.

    Full Text Available  A 32-year-old patient with symptomatic severe aortic regurge, 6 weeks after mitral valve repair, was admitted for aortic valve surgery. No preoperative clinical data consistent with infective endocarditis could be detected. Preoperative transthoracic echocardiography showed aortic leaflet perforation affecting non coronary cusp. During operation, leaflet perforation was detected and closed completely with autologous pericardial patch. No vegetations or abscess could be seen during operation. Iatrogenic aetiology of leaflet perforation after mitral repair was suspected in  this case. Recognition of this complication will help in  avoiding it during mitral valve surgery and expecting it as a possible complication during intraoperative transesophageal echocardiography.

    Perforated plate heat exchangers, consisting of a series of parallel, high thermal conductivity perforated plates, that are separated by a series of spacers that have low thermal conductivity, can provide large values of heat transfer per unit volume. For plates with circular cross-section flow passages, the compactness factor can approach that of gap geometries so that heat exchangers using plates with circular holes can have high performance. The design of low pressure drop heat exchangers is straightforward. Design principles for perforated plate heat exchangers will be given. Experimental results on a prototype system will be presented

    The desert climate is endowed by clear sky conditions, providing an excellent opportunity for optimum utilization of natural light in daylighting building indoor spaces. However, the sunny conditions of the desert skies, in countries like Egypt and Saudi Arabia, result in the admittance of direct solar radiation, which leads to thermal discomfort and the incidence of undesired glare. One type of shading systems that is used to permit daylight while controlling solar penetration is " Solar Screens" Very little research work addressed different design aspects of external Solar Screens and their influence on daylighting performance, especially in desert conditions, although these screens proved their effectiveness in controlling solar radiation in traditional buildings throughout history.This paper reports on the outcomes of an investigation that studied the influence of perforation percentage of Solar Screens on daylighting performance in a typical residential living room of a building in a desert location. The objective was to identify minimum perforation percentage of screen openings that provides adequate illuminance levels in design-specific cases and all-year-round.Research work was divided into three stages. Stage one focused on the analysis of daylighting illuminance levels in specific dates and times, while the second stage was built on the results of the first stage, and addressed year round performance using Dynamic Daylight Performance Metrics (DDPMs). The third stage addressed the possibility of incidence of glare in specific cases where illuminance levels where found very high in some specific points during the analysis of first stage. The research examined the daylighting performance in an indoor space with a number of assumed fixed experimentation parameters that were chosen to represent the principal features of a typical residential living room located in a desert environment setting.Stage one experiments demonstrated that the screens fulfilled the

  5. Robotic Assisted Radical Cystoprostatectomy and Intracorporeal Ileal Conduit Urinary Diversion for a Kidney Transplant Recipient

    Directory of Open Access Journals (Sweden)

    Peter A. Caputo

    Full Text Available ABSTRACT Introduction and Objectives: Robotic assisted radical cystectomy (RARC is an alternative to open radical cystectomy. As experience is gained with the RARC approach the technique is being applied to more complex surgical cases. We describe here our technique for RARC with intracorporeal ileal conduit urinary diversion for a renal transplant recipient. Materials and Methods: The patient is a 60-year old man with high-grade muscle invasive bladder cancer. He has a history of renal failure due to polycystic kidney disease and received a deceased donor renal transplant in 2008. His hospital course at time of transplant was complicated by low-level BK virus viremia. Interestingly his trans-urethral bladder tumor resection specimen at time of bladder cancer diagnosis stained positive for SV40. His native kidneys were anuric so bilateral laparoscopic nephrectomy was performed in a staged fashion 2 weeks prior to RARC. Our surgical technique utilizes 6 trocars, of note a 12-mm assistant trocar is placed 1 cm superior to the pubic symphysis, and this trocar is solely used to pass a laparoscopic stapler to facilitate the excision of the ileal segment and the stapled enteric anastomosis. Surgical steps include: identification of native ureters bilaterally (removed en bloc with the bladder specimen; identification of the transplanted ureter at the right bladder dome; posterior bladder and prostate dissection along Denonvilliers’ fascia; development of the space of Retzius; ligation and transection of the bladder and prostate vascular bundles; apical prostate dissection and transection of urethra; left pelvic lymphadenectomy; ilium resection for creation of the ileal conduit; stapled enteric anastomosis; ureteroileal anastomosis; maturation of the ileal conduit stoma. Results: The surgery had no intraoperative complications. Operative time was 443 minutes (7.4 hours. Estimated blood loss was 250 cc. Length of hospital stay was 5 days. The patient

    Full Text Available Background: The gold standard of the management of rectal cancer in the middle and lower parts is low anterior resection with coloanal anastomosis. About 50% of the patients undergoing this procedure might experience some complications because of the low capacity of the neorectum. The aim of this study was to evaluate ileal J-pouch interposition as a neorectum between the anal canal and the remaining colon in comparison to coloanal anastomosis and transverse coloplasty. Methods: Twelve dogs, weighing 23-27 kg, were divided into three groups. After laparotomy, the volume of the primary rectum was measured so that it could be compared with that of the neorectum at the end of the study. After rectal resection in Group A, the colon was directly anastomosed to the anus. In Group B, a 5-cm longitudinal incision was made 2 cm proximal to the anastomosis and was sutured transversely (coloplasty. In Group C, a 5-cm ileal J-pouch was interposed between the colon and anus. After 8 weeks, the neorectum was evaluated for volume, radiology, and pathology. Results: All the samples were alive until the end of the study. The healing of the anastomotic lines was acceptable (pathologically in all. The mean volume expansion was 20.9% in Group A, 21.7% in Group B, and 118.2% in Group C, with the latter being significantly higher than that of the other groups (P=0.03. Colon J-pouch and coloplasty after proctectomy in some situations have not been performable. This study evaluated the performance of ileal J-pouch interposition. Conclusion: This study showed that ileal J-pouch interposition might produce an acceptable reservoir function and that it seems feasible and safe in selected cases.

    The pathological changes and the risk of developing cancer in the ileal pouch mucosa of patients who received restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) were studied. The presence or absence of remaining rectal mucosa below the IPAA in both patients with stapled and handsewn IPAA was also examined. Endoscopy of the ileal pouch was performed on 38 patients at 4, 12, 18 and 36 months after restorative proctocolectomy with ileal pouch. Mucosal biopsy specimens were taken from the ileal reservoir in order to assess the histological incidence of inflammation. In 23 patients, biopsies were taken to perform cytometric DNA analysis. Clinical symptoms of pouchitis (over six evacuations in 24 hours, night-time evacuations, leakage of feces, bloody diarrhea, abdominal pain and fever) were recorded and correlated with the histological findings. Biopsies were also sampled below the ileo-anal anastomosis (IPAA) in order to identify residual rectal mucosa. Results of histological assessment showed various degrees of chronic inflammation increasing over time (from 42 to 60%) while the presence of both acute and chronic inflammation of the reservoir was less frequent (from 18 to 30%). Villous atrophy was present in 39-68% of patients and the grade of villous atrophy was correlated to the grade of inflammation. Clinical pouchitis was present in 3 to 8% of cases at the different controls and it was always associated with the highest grade of histological inflammation and severe villous atrophy. No significant alteration of the DNA cellular content was observed. Very low incidence of aneuploidy (0.7-1% Ex.R.) has been reported in three cases. However, we found dysplasia in only one patient who underwent surgical treatment for familial polyposis coli. IPAA evaluation showed no residual rectal mucosa in 40% of cases with stapled IPAA; in the remaining 60%, we found a small amount of rectal mucosa (maximum 1 cm). We did not find rectal mucosa after handsewn IPAA

  8. External perforated window Solar Screens: The effect of screen depth and perforation ratio on energy performance in extreme desert environments

    KAUST Repository

    Sherif, A.

    2012-09-01

    In hot arid desert environments, the solar radiation passing through windows increases the cooling loads and the energy consumption of buildings. Shading of windows can reduce these loads. Unlike the woven solar screens, wooden solar screens have a thickness that provides selective shading properties. Perforated wooden solar screens were traditionally used for windows shading. Developing modern types of these shading systems can lead to significant energy savings. The paper addresses the influence of changing the perforation percentage and depth of these screens on the annual energy loads, hence defining the optimum depth/perforation configurations for various window orientations. Series of experiments were performed using the EnergyPlus simulation software for a typical residential building in the Kharga Oasis, located in the Egyptian desert. A range of perforation percentages and depths were tested. Conclusions prove that external fixed deep perforated solar screens could effectively achieve energy savings up to 30% of the total energy consumption in the West and South orientations. Optimum range of depths and perforation percentages were recommended. These are: 80-90% perforation rate and 1:1 depth/opening width ratio. These lighter and deeper solar screen configurations were found to be more efficient in energy consumption in comparison with the traditional ones. © 2012 Elsevier B.V. All rights reserved.

    Abdominal donor-site flaps based on the deep inferior epigastric artery (DIEA) are the most common flaps used in autologous breast reconstruction. With significant variation in the vascular anatomy of the DIEA, preoperative imaging is desirable. Computed tomographic angiography, recently described for this purpose, uniquely demonstrates the branching pattern of the DIEA. The authors sought to correlate the DIEA branching pattern to the location and course of perforators as a preoperative planning tool for perforator flaps. Forty-five cadaveric hemi-abdominal walls were used for contrast injection of the DIEA with subsequent radiographic imaging. The branching pattern on radiography was thus correlated to the location and intramuscular course of perforators, from the main DIEA trunk to the point of the penetrating rectus sheath. The DIEA branching pattern correlated closely with the course of perforators. A bifurcating (type II) branching pattern demonstrated a reduced transverse distance traversed by each perforator, whereas a trifurcating (type III) branching pattern demonstrated significantly greater transverse distances (p = 0.0002). Type I vessels were intermediate. Vessel branching type, however, displayed no significant correlation with the number of perforators (p = 0.56). The distances traversed by perforators were significantly reduced with a bifurcating branching pattern of the DIEA, particularly those originating from the lateral branch, and were greatest with a trifurcating branching pattern. Increased transverse distances correlate with greater rectus muscle sacrificed during perforator flap surgery. As computed tomographic angiography is the optimal modality for demonstrating this pattern preoperatively, the authors suggest its use for preoperative assessment in transverse rectus abdominis musculocutaneous and DIEA perforator flaps.

    Full Text Available Lead perforation is a major complication of cardiac rhythm management devices (CRMD, occurring in about 1%. While most lead perforations occur early, numerous instances of delayed lead perforation (occurring >30 days after implantation have been reported in the last few years. Only about 40 such cases have been published, with the majority occurring <1 year after implantation. Herein, we describe the case of an 84-year-old female who presented with recurrent syncope and was diagnosed to have delayed pacemaker lead perforation 4.8 years after implantation. Through this report, we intend to highlight the increasing use of CRMD in elderly patients, and the lifelong risk of complications with these devices. Presentation can be atypical and a high index of suspicion is necessary for diagnosis.

    The purpose of this study was to report the CT findings of four patients with hepatic abscess secondary to perforated acute cholecystitis. We retrospectively reviewed the CT findings of four patients with surgically proven hepatic abscess secondary to perforated acute cholecystitis. CT findings were analysed with respect to the observation of the gallbladder, pericholecystic space, hepatic lesions, and peritoneal cavity. All patients underwent cholecystectomy, with drainage of the hepatic abscess. CT findings of hepatic abscess secondary to perforated acute cholecystitis were hypodense mass formation in the pericholecystic space(n=3), irreguarity and wall defect of Gallbladder(n=4), thickened Gallbladder wall(n=4), stone with debris(n=4), and local or diffuse infiltration of the pericholecystic area(n=3), omentum, and mesentery. CT was helpful in diagnosing the hepatic abscess secondary to perforated acute cholecystitis.

    2016-12-01

    The chronic use of synthetic cannabinoids (SCs) which has become an increasingly prevalent problem can rarely cause gastric and duodenal ulcer because of their effects on gastric secretion and emptying. Since peptic ulcer disease (PUD) is a rarely seen entity in patients who consult to the emergency service with complaints of abdominal pain, most of the physicians do not suspect of this clinical diagnosis. Perforation is a mortal complication of PUD, and early diagnosis and emergency surgery are life-saving procedures. A 16-year-old male patient was referred to our emergency service from another center with abdominal distension, complaints of abdominal pain, and bilious vomiting. His medical history revealed that he had been regularly using bonsai for the past 3 years. Plain abdominal radiograms of standing position revealed subdiaphragmatic free air, then we performed laparotomy which disclosed perforation of the first part of the duodenum. Surgical intervention with omental patch and primary closure (Graham patch) was successful. The patient who underwent nasogastric decompression and received antibiotherapy had not experienced any complication during the postoperative follow-up period. Herein, as an unusual manifestation, a patient who developed duodenal perforation following chronic SC use has been reported. In adolescent patients admitted with PUD or its complications to the emergency services, it is important to inquire for the use of addictive substances which are increasingly prevalent in order to determine the etiology.

    2010-01-01

    Full Text Available Background. Tympanic membrane perforation may occur when ear pressures are excessive, including valsalva maneuver associated with active labor and vaginal delivery. A pressure differential across the eardrum of about 5 psi can cause rupture; the increased intraabdominal pressure spikes repeatedly manifested by “pushing” during second-stage labor easily approach (and may exceed this level. Material and Method. We describe a healthy 21-year old nulliparous patient admitted in active labor at 39-weeks' gestational age. Results. Blood appeared asymptomatically in the left ear canal at delivery during active, closed-glottis pushing. Otoscopic examination confirmed perforation of the left tympanic membrane. Complete resolution of the eardrum rupture was noted at postpartum check-up six weeks later. Conclusion. While the precise incidence of intrapartum tympanic membrane rupture is not known, it may be unrecognized without gross blood in the ear canal or subjective hearing loss following delivery. Only one prior published report on tympanic membrane perforation during delivery currently appears in the medical literature; this is the first English language description of the event. Since a vigorous and repetitive valsalva effort is common in normal vaginal delivery, clinicians should be aware of the potential for otic complications associated with the increased intraabdominal pressure characteristic of this technique.

  3. Fouling Resilient Perforated Feed Spacers for Membrane Filtration

    KAUST Repository

    Kerdi, Sarah

    2018-04-24

    The improvement of feed spacers with optimal geometry remains a key challenge for spiral-wound membrane systems in water treatment due to their impact on the hydrodynamic performance and fouling development. In this work, novel spacer designs are proposed by intrinsically modifying cylindrical filaments through perforations. Three symmetric perforated spacers (1-Hole, 2-Hole, and 3-Hole) were in-house 3D-printed and experimentally evaluated in terms of permeate flux, feed channel pressure drop and membrane fouling. Spacer performance is characterized and compared with standard no perforated (0-Hole) design under constant feed pressure and constant feed flow rate. Perforations in the spacer filaments resulted in significantly lowering the net pressure drop across the spacer filled channel. The 3-Hole spacer was found to have the lowest pressure drop (50% - 61%) compared to 0-Hole spacer for various average flow velocities. Regarding permeate flux production, the 0-Hole spacer produced 5.7 L.m-2.h-1 and 6.6 L.m-2.h-1 steady state flux for constant pressure and constant feed flow rate, respectively. The 1-Hole spacer was found to be the most efficient among the perforated spacers with 75% and 23% increase in permeate production at constant pressure and constant feed flow, respectively. Furthermore, membrane surface of 1-Hole spacer was found to be cleanest in terms of fouling, contributing to maintain higher permeate flux production. Hydrodynamic understanding of these perforated spacers is also quantified by performing Direct Numerical Simulation (DNS). The performance enhancement of these perforated spacers is attributed to the formation of micro-jets in the spacer cell that aided in producing enough unsteadiness/turbulence to clean the membrane surface and mitigate fouling phenomena. In the case of 1-Hole spacer, the unsteadiness intensity at the outlet of micro-jets and the shear stress fluctuations created inside the cells are higher than those observed with

    Zenker’s diverticulum is the most common type of diverticulum in the esophagus. Most patients are elderly. Typical symptoms are regurgitation, dysphagia, halitosis and chronic cough. The most common treatments are open surgical diverticulectomy with cricopharyngeal myotomy or diverticulopexy. Most instances of esophageal perforation are iatrogenic. Rapid diagnosis and therapy provide the best chance for survival. If diagnosed early, cervical esophageal perforations can be treated conservative...

    Major scrotal defects may result from infection due to Fournier's gangrene, excision of scrotal skin diseases, traumatic avulsion of scrotal and penile skin, and genital burns. The wide spectrum of bacterial flora of the perineum, difficulty in providing immobilisation, and obtaining a natural contour of the testes make testicular cover very difficult. Various methods have been reported to cover the penoscrotal area, including skin grafting, transposing them to medial thigh skin, and use of local fasciocutaneous or musculocutaneous flaps. In this report, reconstruction using six local medial circumflex femoral artery perforator (MCFAP) flaps was undertaken in five male patients (mean age, 47 years) with complex penoscrotal or perineal wounds. The cause of the wounds in four patients was Fournier's gangrene, and was a wide papillomateous lesion in the other patient. Flap width was 6-10 cm and flap length was 10-18 cm. The results showed that a MCFAP flap provided the testes with a pliable local flap without being bulky and also protected the testicle without increasing the temperature. The other advantage of the MCFAP flap was that the donor-site scar could be concealed in the gluteal crease. Our results demonstrated that the MCFAP flap is an ideal local flap for covering penoscrotal defects. Copyright © 2011 Wiley-Liss, Inc.

    In this study the sealing ability of various materials used to repair furcation perforations was evaluated. Ninety human molars were endodontically treated and a perforation was made in the pulp chamber floor using a round bur. The teeth were inserted into a moistened flower sponge and perforation sites were sealed with one of the following materials: Mineral Trioxide Aggregate (ProRootM), Super-EBA, Vitremer, Hemarcol together with Super-EBA, Hemarcol together with Vitremer, Tricalcium phosphate together with AH26, Cavit W and amalgam. After eight months, the sealing effectiveness of the materials was evaluated in a double-blinded trial under a video-microscope by detecting the penetration of silver nitrate solution (50%w/w) in longitudinal tooth sections. Perforation sites filled with Hemarcol together with Vitremer or with MTA exhibited statistically less silver stain penetration while Cavit W or Tricalcium phosphate together with AH26 sealer failed to effectively seal the perforation sites. MTA alone or Vitremer in combination with a collagen sponge can be used effectively in the treatment of perforations in a furcation area.

    Full Text Available Abstract Background The literature established that, in patients without Boey's risk factors, laparoscopic repair of perforated peptic ulcers, compared to open repair, is associated to lower wound infection rate, less analgesic use, reduction in post operative pain, shorter hospital stay. Some of the main drawbacks are length of operative time and laparoscopic surgeon's experience in intracorporeal knotting. We, for first, report our preliminary experience of perforated peptic ulcers' laparoscopic repair using Medtronic U-Clip®. Methods From January 2008 to June 2008 we performed laparoscopic repair of perforated peptic ulcers using Medtronic U-Clip® in 10 consecutive patients (6 men and 4 women, from 20 to 65 years-old of age. All the patients presented with iuxtapyloric perforated peptic ulcer, not greater than 10 mm, without signs of sepsis, free from major illnesses. The mini-invasive procedure was performed both by skilled and non-skilled laparoscopic surgeons under experts' surveillance. After it was recognized, perforation was sutured using U-Clip® in a full-thickness manner. Results and Discussion We reported no surgical complications in the peri-operative period. The clinical outcome and time needed to perform the intervention didn't change between skilled and non-skilled surgeons. The follow-up at 30 days was good. Conclusion In our experience, the anastomotic device U-Clip® simplifies laparoscopic repair of perforated peptic ulcer, avoiding the need to perform knots and making the procedure safe and easier.

    Full Text Available Introduction. Pharyngoesophageal perforation secondary to barotrauma is a rare phenomenon that can have serious complications if identified late. It is challenging to detect due to nonspecific symptoms. We present a case in which detection proved difficult leading to delayed diagnosis. Case Report. A 27-year-old mechanic presented with haemoptysis, dysphonia, and odynophagia after a car tyre exploded in his face. Flexible nasoendoscopy (FNE revealed blood in the pharynx, thought to represent mucosal haemorrhage. Initial treatment consisted of IV dexamethasone and antibiotics. After 3 days, odynophagia persisted prompting a CT scan. This revealed a defect in the posterior hypopharynx and surgical emphysema in the deep neck tissues. Contrast swallow confirmed posterior hypopharyngeal leak. NG feeding was commenced until repeated contrast swallow confirmed resolution of the defect. Discussion. Prompt nonsurgical management of pharyngoesophageal perforation has good outcomes but untreated perforation can have serious complications. FNE should be performed routinely, but only a contrast swallow can diagnose a functional perforation. Clinicians should have a high index of clinical suspicion when patients present with barotrauma and odynophagia. Patients should be kept nil by mouth until perforation has been excluded. Conclusion. When faced with cases of facial barotrauma, clinicians should have a low threshold for further imaging to exclude pharyngoesophageal perforation.

    Full Text Available Double perforated baffles in rectangular secondary clarifiers were studied to determine whether they contribute to producing high-quality effluents. The Computational Fluid Dynamics (CFD simulations indicated that bio-flocculation occurred at the front of the baffle and the longitudinal movement of the settled sludge was hampered whenever the clarifier had high inflow. Simulation results showed that the rectangular clarifier with the double perforated baffle produced an effluent with lower suspended solid (SS concentrations than the effluent from the clarifier without the baffle. To verify the simulation results, a double perforated baffle was installed in two of the 48 rectangular clarifiers in a 300,000 m3/d-capacity wastewater treatment plant. To study the effect of the baffle on solid removal, the effluent turbidity of the clarifier with and without the double perforated baffle was measured simultaneously. Experimental data showed that the double perforated baffle played a significant role in reducing effluent turbidity. The effluent turbidity reduction ratio with the baffle decreased when the Sludge Volume Index (SVI of the Mixed Liquor Suspended Solids (MLSS was below 100 mL/g. The overall average reduction ratio was 24.3% for SVI < 100 mL/g and 45.1% for SVI > 100 mL/g. The results of this study suggest that double perforated baffles must be installed in secondary rectangular clarifiers to produce high-quality effluent regardless of the operational conditions.

    Full Text Available The perforator-based flaps in the sacral and ischial region is designed according to the localization of perforators that penetrate the gluteus maximus muscle, reach the intra-fascial and supra-fascial planes with the overlying skin forming a rich vascular plexus. The perforator-based flaps described in this article are highly vascularized, have minimal donor site morbidity, and do not require the sacrifice of the gluteus maximus muscle. In a period between April 2008 and March 2009, six patients with sacral pressure sore were reconstructed with propeller flap method based on superior gluteal and parasacral artery perforators. One flap loss was noted. Three cases of ischial pressure sore were reconstructed with longitudinal propeller flap cover, based on inferior gluteal artery perforator. One flap suffered wound infection and dehiscence. Two cases of pilonidal sinus were reconstructed with propeller flap based on parasacral perforators. Both the flaps survived without any complications. Donor sites were closed primarily. In the light of this, they can be considered among the first surgical choices to re-surface soft tissue defects of the sacral and ischial regions. In the series of 11 patients, two patients (18% suffered complications.

    The B lymphocyte-epithelial cell interactions that define the microenvironment of the ileal Peyer's patch, the primary B lymphocyte organ of the fetal lamb, have been replicated in tissue culture. Mixed suspensions of ileal epithelial cells, lymphocytes and fibroblasts from fetuses of 63-103 days of gestation organized into macroscopically visible agglomerates within 72 h. These agglomerates contained translucent spherical cavities and were enclosed within a marginal cell layer and surrounded by an expanding corona of emigrating cells. The lining of the cavities and the marginal layer consisted of well-differentiated, polarized columnar ileal epithelial cells. One population of B lymphocytes in the initial mixed suspension differentiated into two discrete populations reproducing the characteristics of intact fetal ileal Peyer's patches. B cells apposed to follicle-associated epithelium (FAE) within agglomerates underwent apoptosis. The other population of emigrant B cells proliferated and expressed the BAQ44A differentiation marker. Differentiation of ileal epithelial cells into FAE, typical of Peyer's patches, was markedly accelerated. The mutually inductive influences of intestinal epithelial cells and B lymphocytes in these agglomerates replicate normal mid-gestational fetal development of the mucosal immune system and afford new opportunities for its further investigation.

    OBJECTIVES Refluxing perforators contribute to venous ulceration. We sought to describe patient characteristics and procedural factors that (1) impact rates of incompetent perforator vein (IPV) thrombosis with ultrasound-guided sclerotherapy (UGS) and (2) impact the healing of venous ulcers (CEAP 6) without axial reflux. METHODS Retrospective review of UGS of IPV injections from 1/2010–11/2012 identified 73 treated venous ulcers in 62 patients. Patients had no other superficial/axial reflux and were treated with standard wound care and compression. Ultrasound was used to screen for refluxing perforators near ulcer(s), and these were injected with sodium tetradecyl sulfate or polidocanol foam and assessed for thrombosis at 2 weeks. Demographic data, comorbidities, treatment details and outcomes were analyzed. Univariate and multivariable modeling was performed to determine covariates predicting IPV thrombosis and ulcer healing. RESULTS 62 patients with active ulcers for an average of 28 months with compression therapy prior to perforator treatment had an average age of 57.1 years, were 55% male, 36% had a history of DVT and 30% had deep venous reflux. 32 patients (52%) healed ulcers, while 30 patients (48%) had non-healed ulcer(s) in mean follow-up of 30.2 months. Ulcers were treated with 189 injections, with average thrombosis rate of 54%. Of 73 ulcers, 43 ulcers healed (59%), and 30 ulcers did not heal (41%). Patients that healed ulcers had an IPV thrombosis rate of 69 % vs. 38% in patients who did not heal (Pulcer healing found complete IPV thrombosis was a positive predictor (P=.02), while large initial ulcer area was a negative predictor (P=.08). Increased age was associated with fewer ulcer recurrences (P=.05). Hypertension and increased follow-up time predicted increased ulcer recurrences (P=.04, P=.02). Calf vein thrombosis occurred after 3% (6/189) of injections. CONCLUSIONS Thrombosis of IPVs with UGS increases venous ulcer healing in a difficult patient

    Full Text Available Purpose: To report a case series of penetrating injury complicated by occurrence of intraocular cilia. Methods: Retrospective analysis of charts of 11 eyes of 11 patients with penetrating injury and intraocular cilia, presenting between September 1978 and November 1998. Ten eyes underwent surgery for trauma-related problems such as cataract, vitritis, retinal detachment etc., at which time intraocular cilia were removed. One eye did not have surgery and continues to harbour cilia at the posterior perforation site. Results: Metallic wire was responsible for injury in 6 of 11 eyes with intraocular cilia. Five eyes had significant intraocular inflammation. The cilia were located in the anterior segment in 4 eyes; in the posterior segment in 6 eyes and in both in one eye. At the last follow up, 72.7% had 6/18 or better vision. Poor vision in the rest was due to recurrent retinal detachment (2 eyes and macular scarring (1 eye. Conclusion: Intraocular cilia are more commonly associated with injury by a metallic wire. The presentation and management of an injured eye does not seem to be influenced by the presence of cilia in the eye.

    The augmented reality on smart glasses allows the surgeon to visualize three-dimensional virtual objects during surgery, superimposed in real time to the anatomy of the patient. This makes it possible to preserve the vision of the surgical field and to dispose of added computerized information without the need to use a physical surgical guide or a deported screen. The three-dimensional objects that we used and visualized in augmented reality came from the reconstructions made from the CT-scans of the patients. These objects have been transferred through a dedicated application on stereoscopic smart glasses. The positioning and the stabilization of the virtual layers on the anatomy of the patients were obtained thanks to the recognition, by the glasses, of a tracker placed on the skin. We used this technology, in addition to the usual locating methods for preoperative planning and the selection of perforating vessels for 12 patients operated on a breast reconstruction, by perforating flap of deep lower epigastric artery. The "hands-free" smart glasses with two stereoscopic screens make it possible to provide the reconstructive surgeon with binocular visualization in the operative field of the vessels identified with the CT-scan.

    Probably, laparoscopic radical cystectomy with ileal neobladder and neovesicourethral anastomosis is one of the most complex procedures in minimally invasive surgery. Prospective study carried out in 72 patients surgically treated for invasive bladder neoplasia between January 2008 and October 2013. Patients were undergone to radical cystectomy with ileal neobladder (open approach in 33 patients and laparoscopic approach in 39). The study assessed comparatively surgical outcomes, continence rate and postoperative complications. Mean age was 63.5±9 years (64.3 open vs. 62.7 laparoscopic, P=.46) mean surgery time 323.6±78.7 minutes (321.3 vs. 326.5, P=.77), average hospital stay 14.8 days±8,1 (16.2 vs. 13.6, P=.2), transfusion rate 40.3% (66.7% vs. 17.9%, P<.0001) and complications rate 47.2% (63.6% vs. 33.3%, P=.01). Major complications were reported in 29.1% of cases (39.4% open vs. 20,5% laparoscopic, P=.07). With a mean follow-up rate of 42.5±19.2 months (range 15-70), 50 (69.4%) patients remain alive and free of disease. Continence was evaluated in these patients: total continence rate was 38% (50% vs. 27%, P=.09) and diurnal continence rate 58% (70.8% vs. 46.1%, P=.07). Self-catheterization rate was 8% (4.2% vs. 11.5%, P=.67). Total incontinence rate was 34% (25% vs. 42.3%, P=.19). According to our experience, transfusion rate, number and severity of complications are lower in laparoscopic cystectomy with ileal neobladder. No statistically significant impact on operative time and on hospital stay was observed. In patients undergone to laparoscopic approach, continence rate is lower but not statistically significant.

    Urinary tract infection (UTI) is one of the most common complications after radical cystectomy and orthotopic neobladder reconstruction. This study investigated the incidence and implicated pathogen of febrile UTI after ileal neobladder reconstruction and identify clinical and urodynamic parameters associated with febrile UTI. From January 2001 to May 2015, 236 patients who underwent radical cystectomy and ileal neobladder were included in this study. Fifty-five episodes of febrile UTI were identified in 46 patients (19.4%). The probability of febrile UTI was 17.6% and 19.8% at 6 months and 24 months after surgery, respectively. While, Escherichia coli was the most common implicated pathogen (22/55, 40.0%), Enterococcus spp. were the most common pathogen during the first month after surgery (18/33, 54.5%). In multivariate logistic regression analysis, ureteral stricture was an independent risk factor associated with febrile UTI (OR 5.93, P = 0.023). However, ureteral stricture accounted for only 6 episodes (10.9%, 6/55) of febrile UTI. Most episodes of febrile UTI occurred within 6 months after surgery. Thus, to identify risk factors associated with febrile UTI in the initial postoperative period, we assessed videourodynamics within 6 months after surgery in 38 patients. On videourodyamic examination, vesicoureteral reflux (VUR) was identified in 16 patients (42.1%). The rate of VUR presence in patients who had febrile UTI was not significantly different from those in patients without febrile UTI (50% vs. 39.3%, P = 0.556). Patients with febrile UTI had significantly larger residual urine volume (212.0 ± 193.7 vs. 90.5 ± 148.2, P = 0.048) than those without. E. coli and Enterococcus spp. are common pathogens and ureteral stricture and residual urine are risk factors for UTI after ileal neobladder reconstruction.

    The accuracy of prenatal ultrasound examination in detecting jejunal and ileal atresia has been reported in the literature to be highly variable, at 25-90%. The aim of this systematic review was to evaluate the accuracy of prenatal ultrasound in detecting non-duodenal small bowel atresia (ND-SBA). MEDLINE, EMBASE and The Cochrane Library, including The Cochrane Database of Systematic Reviews (CDSR), Database of Abstracts of Reviews of Effects (DARE) and The Cochrane Central Register of Controlled Trials (CENTRAL), were searched electronically. The overall detection rate of jejunal or ileal atresia using ultrasound was reported. The accuracy of using polyhydramnios and dilated loops of bowel as diagnostic signs was also explored. Sixteen studies involving 640 fetuses were included in this review. The detection rate of ND-SBA by prenatal ultrasound was highly variable, with values ranging from 10 to 100%, with an overall prediction of 50.6% (95% CI, 38.0-63.2%). When analyzed separately, the detection rates of jejunal and ileal atresia were 66.3%, (95% CI, 33.9-91.8%) and 25.9% (95% CI, 4.0-58.0%), respectively. Both dilated loops of bowel and polyhydramnios as diagnostic signs for ND-SBA provided a low overall detection rate. The diagnostic performance of prenatal ultrasound in identifying ND-SBA is extremely variable. Large studies are needed in order to identify objective and combined criteria for the diagnosis of these anomalies. Copyright © 2014 ISUOG. Published by John Wiley & Sons Ltd.

    Meat and fish serve as important protein sources in the companion animal diet; however, limited protein digestibility data are available for assessing protein digestibility differences among good-quality protein sources. Beef loin, pork loin, chicken breast, pollock fillet, and salmon fillet were evaluated for composition, protein digestibility, and AA bioavailability using the immobilized digestive enzyme assay, cecectomized rooster assay, and ileally cannulated dog assay. Pollock contained the greatest amount of CP, total essential AA (TEAA), and total nonessential AA (TNEAA; DM basis; 96.9, 38.6, and 50.3%, respectively). Salmon contained the next greatest amounts (92.8, 36.4, and 44.6%), followed by chicken (90.3, 36.1, 43.2%). Beef had the least CP content (82.7%), but had slightly greater TEAA and TNEAA concentrations (33.9, 42.0%) compared with pork (86.2, 33.6, 41.3%). Immobilized digestive enzyme assay values were greatest for pollock fillet (0.71) and least for chicken breast (0.52). Beef loin, pork loin, and salmon fillet were similar (0.63, 0.62, and 0.64, respectively). Standardized TEAA and TNEAA digestibility coefficients, evaluated using the cecectomized rooster assay, were greatest (P protein source. No significant differences (P > 0.05) were found in ileal digestibility of protein. Values ranged from 88.9% for chicken to 90.5% for pork loin and pollock fillet. Ileal TEAA and TNEAA coefficients were not different among test substrates, with values between 91.7 and 92.7%, and 88.8 and 90.4%, respectively. Total tract CP apparent digestibility values ranged from 94.4 to 94.8%, with no differences noted among treatments. Despite marked differences in composition and predicted and standardized digestibility values, when the protein sources were added to diets at a concentration of approximately 30% (25% of total energy intake), no differences in test protein substrates were noted in either ileal or total tract nutrient digestibility.
