    For patients with small bowel and colonic perforations, a definitive diagnosis of the cause of perforation is not necessary before operation. Bowel obstruction and inflammatory bowel disease are the most common causes of nontraumatic intestinal perforations in industrialized countries, whereas infectious causes of intestinal perforations are more common in developing countries. Treatment of small bowel and colonic perforations generally includes intravenous antibiotics and fluid resuscitation, but the specific management of the bowel depends on the underlying cause of the perforation.

    Distant small bowel metastases from head and neck squamous cell carcinomas are extremely rare, and tongue cancer metastasizing to the small bowel has not been previously reported. We describe a 40-year-old male patient who underwent subtotal gross laryngectomy for squamous cell carcinoma of the tongue in February 2007 and then presented in November 2008 with severe abdominal pain. Abdominal computed tomography (CT) and X-rays revealed free air, suggesting intestinal perforation. Emergency surgery revealed a 10-mm perforation at the ileum and a palpable hard tumor at the perforation site. The ileum was resected, and pathologic findings showed squamous cell carcinoma at the perforation site, which was consistent with metastasis from tongue cancer.

    Ingestion of foreign bodies is not an uncommon problem in our society. The patients usually ingest different types of foreign bodies either accidentally or deliberately. Rare in children but adults are not uncommonly affected and are either psychiatric patients or ingest foreign bodies accidentally. Life threatening complications may occur at times due to ingestion of sharp and pointed objects. An interesting case of ingestion of multiple injurious foreign bodies presenting with multiple small intestinal perforations is presented with review of literature.

    The purpose of this article is to illustrate and discuss the various etiologies of perforation of the mesenteric small bowel and associated findings on abdominal CT. Perforation of the mesenteric small bowel is an uncommon cause of an acute abdomen and can be due to various etiologies. In underdeveloped countries, infection is probably the most common cause, while in industrialized nations, perforation may be due to Crohn disease, diverticulitis, foreign body, trauma, tumor, mechanical obstruction, primary ischemic event, or iatrogenic causes. CT is usually the initial imaging examination in patients with an acute abdomen and is sensitive in diagnosing small bowel perforation. CT findings in the setting of small bowel perforation are often subtle, but when present, may help the radiologist determine a specific cause of perforation. The aims of this pictorial essay are to review the various causes of mesenteric small bowel perforation and to discuss and illustrate the CT findings that can help arrive at the diagnosis.

    Small bowel perforation is an emergent medical condition for which the diagnosis is usually not made clinically but by CT, a common imaging modality used for the diagnosis of acute abdomen. Direct CT features that suggest perforation include extraluminal air and oral contrast, which are often associated with secondary CT signs of bowel pathology. This pictorial review illustrates the CT findings of small bowel perforation caused by various clinical entities.

    Thus far, there have been tries of detection of disease using fluorescent materials. We introduce the chlorophyll derivatives from food plants, which have longer-wavelength emissions (at >650 nm) than those of fluorescence of tissues and organs, for detection of bowel perforation. To figure out the possibility of fluorescence spectroscopy as a monitoring sensor of bowel perforation, fluorescence from organs of rodent models, intestinal and peritoneal fluids of rodent models and human were analyzed. In IVIS fluorescence image of rodent abdominal organ, visualization of perforated area only was possible when threshold of image is extremely finely controlled. Generally, both perforated area of bowel and normal bowel which filled with large amount of chlorophyll derivatives were visualized with fluorescence. The fluorescence from chlorophyll derivatives penetrated through the normal bowel wall makes difficult to distinguish perforation area from normal bowel with direct visualization of fluorescence. However, intestinal fluids containing chlorophyll derivatives from food contents can leak from perforation sites in situation of bowel perforation. It may show brighter and longer-wavelength regime emissions of chlorophyll derivatives than those of pure peritoneal fluid or bioorgans. Peritoneal fluid mixed with intestinal fluids show much brighter emissions in longer wavelength (at>650 nm) than those of pure peritoneal fluid. In addition, irrigation fluid, which is used for the cleansing of organ and peritoneal cavity, made of mixed intestinal and peritoneal fluid diluted with physiologic saline also can be monitored bowel perforation during surgery.

    Although the diagnosis of bowel perforation is frequently straightforward, it may be difficult in the neonate. Clinical signs may be limited to abdominal distension. If the patient is on assisted ventilation, pneumoperitoneum may be due to air tracking down from the chest rather than perforation. Perforation in infants in whom the diagnosis could not readily be made from the clinical findings and plain radiographs was apparent when oral metrizamide was employed. This suggests that metrizamide can be a valuable adjunct in some cases of neonatal bowel perforation.

    Acute intestinal ischemia continues to be a challenging diagnostic problem with high mortality. We describe a rare case of acute intestinal necrosis, due to vasculitis, related with chemotherapy. A patient was examined in our emergency department, presenting with abdominal pain. Three months before he had undergone an operation for lung carcinoma (lobectomy) and received chemotherapy. CT of the abdomen demonstrated free air in 10 different locations: hepatic part of the portal vein, branches of mesenteric veins, femoral and iliac veins, the bowel wall, peritoneal cavity and retroperitoneal space, abdominal muscles, inguinal canals, meso-sigmoid space, and in the para-rectal space. Moreover, pathological findings revealed that the free air in the peritoneum and retropneumoperitoneum occurred without intestinal perforation, but with transudation through the necrotic bowel wall. This is a rare complication of chemotherapy. This case refers to the unusual CT findings which appeared in this patient. The key to a better outcome is early diagnosis of this condition and the CT examination of the abdomen plays an important role. PMID:24349710

    A 45-year-old man of Middle Eastern origin, morbid obese, with a body mass index of 39 had an intra-gastric balloon, filled with 500 mL of saline/methylene blue and intended as definite therapy, inserted some 8 wk previously. He was admitted to the emergency department with abdominal cramps. An ultrasound of the abdomen was performed in ER which confirmed the balloon to be in place without any abnormality. He was discharged home on symptomatic medication. Patient remains symptomatic therefore he reported back to ER 2 d later. Computed tomography scan was performed this time for further evaluation which revealed a metallic ring present in the small bowel while the intra-gastric balloon was in its proper position. There was no clinical or radiological sign of intestinal obstruction. Patient was hospitalized for observation and conservative management. The following night, patient experienced sudden and severe abdominal pain, therefore an X-ray of the abdomen in erect position was done, which showed free air under the right dome of diaphragm. Patient was transferred to O.R for emergency laparotomy. There were two small perforations identified at the site of the metallic ring entrapment. The ring was removed and the perforations were repaired. Due to increasing prevalence of obesity and advances in modalities for its management, physicians should be aware of treatment options, their benefits, complications and clinical presentation of the known complications. Physicians need to be updated to approach these complications within time, to avoid life-threatening situations caused by these appliances. PMID:25901223

    Accidental ingestion of foreign bodies is a common problem in infants and childhood, but ingestion of magnetic construction toys is very rare. In the case of ingestion of multiple parts of these magnetic construction toys, they may attract each other through the intestinal walls, causing pressure necrosis, perforation, fistula formation or intestinal obstruction. A 20-month-old boy presented with a three-day history of abdominal pain and bilious vomiting. Physical examination revealed a slighted distended abdomen. The -white blood cell count was increased, but the C-reactive protein was normal. Ultrasound and X-ray of the abdomen showed a distended bowel loop in the right upper quadrant, a moderate amount of free intraperitoneal liquid and 4 foreign bodies. Emergency laparotomy was performed and 2 perforations in the ileum were detected. The perforations were caused by a magnetic construction toy and 2 iron globes. The fourth foreign body was a glass marble. The foreign bodies were removed, both perforations were primarily sutured. The child was discharged on postoperative day 10 after an uneventful recovery. Parents should be warned against the potential dangers of children's constructions toys that contain these kinds of magnets.

    Summary ACTH-secreting phaeochromocytoma (ASP) is a rare cause of ACTH-dependent Cushing’s syndrome (CS). We report the case of a 63-year-old female presenting with CS secondary to an ASP complicated by bowel perforation. This case report highlights ASP as an uncommon but important cause of ectopic ACTH secretion (EAS). There have been 29 cases of ASP, all of which were unilateral and benign, but associated with significant complications. Patients presenting with ASP have the potential for cure with unilateral adrenalectomy. Given this promising prognosis if recognised, ASP should be considered in the diagnostic workup of ACTH-dependent CS. As this case demonstrates, gastrointestinal complications can arise from severe hypercortisolaemia associated with CS. Early medical and surgical intervention is imperative as mortality approaches 50% once bowel perforation occurs. Learning points Consider phaeochromocytoma in the diagnostic workup of ACTH-dependent CS; screen with plasma metanephrines or urinary catecholamines. Serial screening may be required if ACTH-secreting phaeochromocytoma is suspected, as absolute levels can be misleading. Early catecholamine receptor blockade and adrenal synthesis blockade may avoid the need for rescue bilateral adrenalectomy in ACTH-secreting phaeochromocytoma. Consider early medical or surgical management when gastrointestinal features are present in patients with CS, as bowel perforation due to severe hypercortisolaemia can occur and is associated with significant mortality.

    We describe explosive combustion of a gas filled peritoneum from a handheld electrosurgery electrode used to enter the abdomen. The pneumoperitoneum was due to small bowel perforation and peritonitis had been established for at least two days. No injury was caused to either the patient or medical staff. This rare occurrence has only been described once before. Surgeons should be aware of the possible combustion of bowel gas, whether on opening bowel or the peritoneum after bowel perforation.

    A very rare case of traumatic diaphragmatic hernia is reported in a 65-year-old woman who presented 46 years after her initial thoracoabdominal injury with tension faecopneumothorax caused by a perforated colon in the chest cavity. She presented in a critical condition with severe respiratory distress, sepsis and acute kidney injury. She had a long-standing history of bronchial asthma with respiratory complications and had experienced progressive shortness of breath for the past year. A recent CT scan had excluded the presence of a diaphragmatic hernia but showed a significantly raised left hemidiaphragm. On admission, chest X-rays showed a significantly raised left hemidiaphragm and mediastinal shift, but the possibility of a diaphragmatic hernia with strangulated bowel in the chest was not suspected until the patient was reviewed by the surgical and intensive care unit consultants the next morning and a repeat CT performed. She had a successful outcome after her emergency operation.

    We present a case of distal large bowel obstruction, in the setting of a competent ileocaecal valve, the caecum is the most common site of perforation (for Laplace's law). We describe a case of obstruction at the rectum due to constricting carcinomatous growth, presenting with perforation of transverse colon (against Laplace's law). A 60-year-old women presented to the emergency department with acute abdominal pain. The pain was preceded by 3 days of intestinal obstruction. Clinically there was guarding and rigidity. Straight X-ray of the abdomen revealed free gas under diaphragm. Surgical exploration revealed transverse colon perforation with carcinoma of rectum. Loop transverse colostomy was performed as the patient was very sick. The patient improved slowly in the intensive care unit. To conclude, even though the caecum is the most common site for perforation in case of distal obstruction, perforation of transverse colon can occur otherwise as a unique presentation.

    Background: Bowel perforation is a serious but rare complication after a ventriculoperitoneal shunt (VPS) procedure. Prior studies have reported spontaneous bowel perforation after VPS placement in adults of up to 0.07%. Transanal catheter protrusion is a potential presentation of VPS bowel perforation and places a patient at risk for both peritonitis and ventriculitis/meningitis via retrograde migration of bacteria. This delayed complication can be fatal if unrecognized, with a 15% risk of mortality secondary to ventriculitis, peritonitis, or sepsis. Case Description: We describe a unique case of a patient with distal VPS catheter protrusion from the anus whose bowel perforation did not cause clinical sequelae of infection. We were able to manage the patient without laparotomy. Conclusions: A subset of patients can be managed without laparotomy and only with externalization of the ventricular shunt with antibiotics until the cerebrospinal fluid cultures finalize without growth.

    We aim to determine risk factors and clinical outcomes for bowel perforation in premature infants with NEC. We analyzed clinical data of 57 cases of premature infants with NEC at our NICU between January 2010 and December 2012. Based on the presence of bowel perforation, we divided these infants into two groups: perforated NEC group (n = 10) and nonperforated NEC group (n = 47). We compared general information, clinical characteristics, and laboratory findings between groups. The perforated NEC group, compared to the nonperforated NEC group, had significantly lesser gestational age, lower birth weight, higher prevalence of apnea, mechanical ventilation, sepsis and shock, lower blood pH, higher levels of blood glucose, abnormal WBC count and thrombocytopenia, and elevated CRP (all P < 0.05). Moreover, the perforated NEC group had significantly longer durations of fasting and TPN usage, higher incidences of EUGR and cholestasis, longer duration of antibiotics, higher frequency of advanced antibiotics use, and poorer prognosis than the nonperforated NEC group (all P < 0.05). Bowel perforation in premature infants with NEC was associated with multiple risk factors. Early identification of some of these risk factors in premature infants with NEC may help implement early intervention to reduce the incidence of bowel perforation and thereby improve the prognosis.

    Esophageal perforation is a condition associated with high morbidity and mortality rates; it requires early diagnosis and treatment. The most common complication of esophageal rupture is mediastinitis. There are several case reports in the literature of mediastinitis secondary to esophageal perforation and development of aortic pseudoaneurysm as a complication. We report the case of a patient with an 8-day history of esophageal perforation due to foreign body (fishbone) with mediastinitis and aortic pseudoaneurysm. The diagnosis was made using Computed Tomography (CT) with intravenous and oral water-soluble contrast material. An esophagogastroduodenoscopy did not detect the perforation. PMID:26977330

    2015-06-08

    A 7-year-old boy presented in septic shock secondary to appendicitis with generalised peritonitis. Following crystalloid resuscitation, he underwent surgery. Faecopurulent contamination and free air were found. This was secondary to a perforated and gangrenous appendix, multiple large and small bowel segments with perforations, patches of necrosis, interspersed with healthy bowel and segments of questionable viability. There was also a perforated duodenal ulcer. Necrotic segments were resected using a 'clip-and-drop' technique to shorten operative duration and guide resection to preserve bowel length. After six laparotomies and multiple bowel resections, the child was discharged home with an ileostomy that was subsequently reversed. He is currently on a normal diet and pursuing all activities appropriate for his age. Perforated appendicitis can be associated with widespread bowel necrosis and multiple perforations. A conservative damage limitation approach using the 'clip-and-drop' technique and relook laparotomies is useful in the management of extensive bowel necrosis in children.

    Complications of cecal retroflexion performed during colonoscopy have not previously been reported to occur. We report a case of contained colonic perforation secondary to using cecal retroflexion technique to examine the colon, and review available published reports of complications associated with this technique. We conclude that complications may rarely occur with use of cecal retroflexion, and that the clinical benefit of this technique is uncertain.

    Bowel perforation is a rare complication of mid-urethral sling procedures and is usually reported shortly after the surgery. We report a remotely discovered asymptomatic bowel injury found at the time of subsequent surgery. The patient with a history of several prior pelvic surgeries underwent an uneventful retropubic mid-urethral sling placement. Five years later, during an abdominal sacrocolpopexy procedure, mesh from the mid-urethral sling was found perforating the wall of the cecum and fixating it to the right pelvic sidewall. Cecal wedge resection was performed to excise the sling mesh. Asymptomatic bowel perforation by mid-urethral sling mesh has not been previously reported. Pelvic and abdominal surgeons should be aware of the possibility of finding this injury in patients with prior sling surgeries.

    An 82-year-old man presented with signs and symptoms that were suggestive of acute cholecystitis. He underwent a laparoscopic cholecystectomy. During the intervention, a wooden foreign body was removed from the infiltrated omentum, probably after it had perforated the gastric antrum. The gastric perforation had led to a secondary infection of the gallbladder. The presumed gastric perforation was treated conservatively, and the patient recovered well and was discharged after 7 days. Secondary inflamed gallbladders are rare; the current case is, to the best of our knowledge, the first case reporting a secondary infection of the gallbladder due to a gastric perforation. Clinicians should be aware of possible ingestion of foreign bodies in elderly patients wearing dental prosthetic devices.

    We report a rare case of visceral injury after totally extraperitoneal endoscopic inguinal hernia repair. A 48-year-old man underwent needlescopic totally extraperitoneal repair of a direct inguinal hernia. Bleeding from a branch of the inferior epigastric vessels occurred at the beginning of the extraperitoneal dissection with a monopolar electrosurgical device. Hemostasis was prolonged. However, herniorrhaphy and mesh repair were successfully performed, and no peritoneal disruption or pneumoperitoneum was visible. The patient was discharged home on the next day. However, 30 h after this operation, he underwent diagnostic and operative laparoscopy because of acute abdominal pain. Ileal perforation was found and repaired, and pathological examination indicated cautery artifact. Thus, thermal damage to the ileum during the initial operation may have caused the bowel perforation. To the best of our knowledge, no other cases of bowel perforation after totally extraperitoneal repair without peritoneal disruption have been reported.

    This report describes a case of aesthetic and functional abdominal wall reconstruction performed to salvage a deformed, scarred, and herniated anterior abdomen after severe peritonitis and partial rectus muscle necrosis secondary to multiple bowel perforations sustained during liposuction performed in a cosmetic clinic. The diagnosis of intestinal perforation was missed intraoperatively and in the immediate postoperative period. The patient was admitted 4 days after the surgery to the intensive therapy unit in septicemic shock. After resuscitation and stabilization, she was treated by debridement of the abdominal wall, bowel resection, and temporary jejunostomy and colostomy (reversed 10 months later). She was referred 18 months after liposuction to the Plastic Surgery Service with a large central midline abdominal incisional hernia presenting with thinned out skin (14 × 11 cm) overlying adherent bowel. A components separation technique was successfully used to reconstruct the abdominal wall, with no recurrent herniation 2 years later. Survivors of bowel perforations sustained during abdominal liposuction may later present with challenging aesthetic and functional problems, as described in this report. These long-term sequelae have not been addressed hitherto in the literature.

    Tension-free vaginal tape (TVT) is commonly considered as the first line of treatment for stress urinary incontinence (SUI) with demonstrated efficacy and limited complications. An 82-year-old woman with complete uterine procidentia and SUI underwent a Le Forte colpocleisis, TVT, posterior repair, and cystoscopy. A 4-cm bulge was noted over the site of the left TVT incision on postoperative day 1. On postoperative day 3, she developed bilious vomiting with slight abdominal distention. Computed tomography scan showed a strangulated left inguinal hernia. An immediate exploratory laparotomy noted an inguinal hernia displaced medially with loops of small bowel in the hernia sac. Although properly positioned, one loop of bowel was perforated by the sling mesh. A small bowel resection was performed and the mesh trimmed below the resection on involved side. At 2 months postoperative visit, the patient was asymptomatic, denied stress or urge incontinence. Vaginal examination noted well-supported vaginal walls.

  13. Bowel perforation secondary to illegally induced abortion: a tertiary hospital experience in Tanzania

    2012-01-01

    Background Bowel perforation though rarely reported is a serious complication of induced abortion, which is often performed illegally by persons without any medical training in developing countries. A sudden increase in the number of patients in our centre in recent years prompted the authors to analyze this problem. The study was conducted to describe our own experiences in the surgical management of these patients. Methods This was a retrospective study involving patients who were jointly managed by the surgical and gynecological teams at Bugando Medical Centre (BMC) for bowel perforation secondary to illegally induced abortion from January 2002 to December 2011. The statistical analysis was performed using SPSS version 17.0. Results A total of 68 patients (representing 4.2% of cases) were enrolled in the study. Their ages ranged from 14 to 45 years with a median age of 21 years. Majority of patients were, secondary school students/leavers (70.6%), unmarried (88.2%), nulliparous (80.9%), unemployed (82.4%) and most of them were dependent member of the family. Previous history of contraceptive use was reported in only 14.7% of cases. The majority of patients (79.4%) had procured the abortion in the 2nd trimester. Dilatation and curettage (82.4%) was the most common reported method used in procuring abortion. The interval from termination of pregnancy to presentation in hospital ranged from 1 to 14 days (median 6 days ). The ileum (51.5%) and sigmoid colon (22.1%) was the most common portions of the bowel affected. Resection and anastomosis with uterine repair was the most common (86.8%) surgical procedure performed. Complication and mortality rates were 47.1% and 10.3% respectively. According to multivariate logistic regression analysis, gestational age at termination of pregnancy, delayed presentation, delayed surgical treatment and presence of complications were significantly associated with mortality (P<0.001).

    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.

    Chlorophylls occur abundantly in food plants and show bright emission bands at long-wavelength regions (∼675 and ∼720 nm) compared to the autofluorescence of animal organs and peritoneal fluids. The use of these emissions as biomarkers for monitoring bowel perforation with a modality that does not involve synthetic contrast agents seems promising. To validate this, we measured the fluorescence spectra of rat organs, human peritoneal and intestinal fluids, and human intestinal fluids diluted with physiological saline. The developed technique showed a high detection sensitivity (∼50 ppm) under irrigation for abdominal surgery, highlighting the potential of this tool in the surgical setting.

    Ingestion of foreign bodies in the pediatric population is common and magnet ingestion is known to cause a significant morbidity. Rare-earth magnets are small 3-6 mm diameter spherical powerful magnets that are sold as popular desk toys for adults and were previously found in construction toys in attractive colors for children to play with. We describe 2 young healthy children who ingested rare-earth magnets Buckyballs while playing with these magnetic toys and later presented in emergency with acute abdomen. Abdominal imaging revealed several (26 and 5) pieces of rare-earth magnets in the bowel loops. Emergency surgical exploration revealed multiple gastrointestinal perforations and fistula formation at sites of bowel entrapment in between strong magnets apposed to one another. We highlight the potential dangers of rare-earth magnets in children and suggest increasing public awareness about risks involved in rare-earth magnets ingestion by children to overcome this serious public health issue.

    We present a rare complication of abdominal liposuction: bowel perforation and necrotizing fasciitis. Because of bilateral lumbar hernia, a 56-year-old woman had caecum and descending colon perforation during lipoplasty. She had septic shock syndrome at her admission. The authors treated this complex wound with several debridement, omental flap, NPWT and split-thickness skin graft. The incidence of abdominal wall perforation with visceral injury is 14 in 100,000 liposuctions performed. There are only 12 cases of bowel perforation in literature but this complication is probably underestimated. Prompt surgical debridement is absolutely mandatory in this life threatening scenario. Lumbar hernia is very rare and should be ruled out before every abdominal liposuction clinically or with imaging modalities. PMID:25593436

    Non-traumatic small bowel perforation is rare in adults but carries a high morbidity and mortality. The diagnosis is made on clinical suspicion, and the most common causes in developing countries are infectious diseases, being cytomegalovirus infection in immunocompromised patients the main etiology. We describe a patient with a recently diagnosed advanced stage HIV infection and an intestinal perforation associated with cytomegalovirus immune reconstitution inflammatory syndrome after highly active antiretroviral therapy initiation.

    We report a case of a 79-year-old female presenting with hematemesis and melena 9 years after ventral hernioplasty with mesh. After initial normal endoscopy and colonoscopy, video capsule endoscopy revealed a metallic wire mesh perforating the jejunum. Abdominal computed tomography did not identify a perforation although metallic mesh was visualized close to the small bowel. We present the first ventral hernia mesh perforation diagnosed via video capsule endoscopy. Such a finding emphasizes the importance of a complete diagnostic workup when approaching a patient with obscure overt gastrointestinal bleeding. PMID:28008400

    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. PMID:17485806

    Vehicle collisions represent more than 75% of mechanism of blunt abdominal trauma. In spite of the incomparable improvement of car safety devices, recent studies pointed out that the air bags might cause injuries, specially when it is not associated with seatbelt. In fact, some studies pointed out that crash victims using air bags alone have increased injury severity, hospitalisations, thoracoabdominal procedure, and rehabilitation. Some of the most frequently injured organs reported from air bag deployment are the liver (38%), the spleen (23%) and digestive system (17%). Injury of the hollow viscera are far less common. In particular, blunt abdominal trauma resulting in small bowel perforation is an infrequent lesion. These injuries are difficult to diagnose because specific signs are poor and a delay in treatment increases mortality and morbidity of the patients. We describe a case of thoracoabdominal trauma that occurred during a head-on collision after an air bag deployment without seatbelt use.

  2. Characterization and literature review of bowel perforation injuring using argon beam coagulation

    INTRODUCTION: Argon Beam Coagulation (ABC®) technology is used in conjunction with the ConMed ABCFlex® Probe to provide non-contact hemostasis, coagulation, and tissue devitalization during endoscopic procedures. ABC provides a superficial tissue effect; however, there is a risk of bowel perforation. To better understand the settings that lead to perforation, this study reviews the literature and provides an ex vivo characterization of the ABCFlex Probe tissue effect at different settings when used at small distances. METHODS: Depth of thermal tissue effect was characterized to determine the effect of three parameters: power (W), distance from probe tip to tissue (mm) and application duration (s). 3 ABCFlex Probes were used to create 15 samples on ex vivo porcine small intestine for each combination of parameters. The depth of tissue effect for each sample was measured using a light microscope. RESULTS: Depth of tissue effect increases as power and application time increases. An increase of distance from the probe tip to the tissue results in a decrease in depth of tissue effect from a near contact to 1mm distance. Depth of tissue effect doesn't significantly change from 1mm to 3mm distance. CONCLUSION: ABCFlex Probe can be used to achieve hemostasis in endoscopic procedures. Increasing power and application time increases the depth of thermal effect while increasing distance from the probe time to the surface of the tissue decreases the depth of tissue effect.

    Patient: Male, 18 Final Diagnosis: Perforation Symptoms: Abdominal pain Medication: — Clinical Procedure: Endoscopy Specialty: Surgery Objective: Rare disease Background: Toothpick ingestion is implicated in bowel injuries that may cause violent complications, mimicking diseases causing acute abdomen. Case Report: A 18-year-old man was admitted with a 3-day history of a swallowed wooden toothpick. The patient had tenderness in the left flank area. Computed tomography indicated toothpick impaction at the splenic flexura of the colon. It was successfully removed with colonoscopy. After the procedure, abdominal radiography showed free air as a sign of perforation. Along with conservative management, the patient was discharged without surgery. Conclusions: There is need for greater awareness of the hazardous of an ingested toothpick. Endoscopic approach should be considered in the first-line management of toothpick perforations.

    Perforation of the Meckel’s diverticulum due to tuberculosis is a rare phenomenon. A 45 years old male who presented with perforation peritonitis was found to have a synchronous dual perforation involving the ileum and the Meckel’s diverticulum, due to intestinal tuberculosis. In addition to this, the Meckel’s diverticulum was found to have a daughter diverticulum (diverticulum within diverticulum), which was probably pulsion or traction diverticulum as it did not have all layers of the intestinal wall. Such daughter diverticulum associated with a Meckel’s diverticulum is very unusual. All these factors make this a unique case which is hence reported here. PMID:27956994

    A case of late dislocation of a disc spacer L5/S1 with perforation of the sigmoid colon and transanal passage 4 years after implantation is reported. The objective is to describe an uncommon complication of anterior endoscopic spondylodesis L5/S1. To our knowledge, this is the first report on this rare complication. A 39-year-old patient suffering from a spondylolisthesis L5/S1 (Meyerding grade 2) with bilateral lysis L5 was operated with posterior instrumentation L5/S1 and anterior endoscopic insertion of two disc spacers. 4 years after surgery the patient noticed one of the spacers in the toilet. Radiographic examination of the colon with contrast dye revealed a perforation at the distal sigmoid colon. At the lumbosacral junction there was a bony defect at the site of the absent spacer and an anterior dislocation of the second spacer. A partial resection of the colon at the perforation site with end-to-end anastomosis was performed. The second spacer was removed, and the defect was packed with autologous cancellous bone and local antibiotics. The further course was uneventful. 2 weeks postoperatively the patient was discharged without signs of infection. The radiographic examination after 6 months showed healing of the bone graft with bony fusion L5/S1. In case of incomplete or absent bony fusion the dislocation of intradiscal spacers may arise even years after the primary surgery. In consequence periodical radiographic examinations of spinal instrumentations are recommended until complete bony fusion occurred. Unclear abdominal symptoms following anterior spine surgery require immediate examination.

    The coexistence of clostridial gas gangrene and a gynecologic malignancy is extremely rare, with very few cases involving ovarian cancer. A patient originally presented to our gynecologic oncology service with stage IV ovarian cancer; she underwent a diagnostic laparoscopy and neoadjuvant chemotherapy. On postoperative day 6, the patient developed severe abdominal pain, nausea, and emesis, suggestive of a bowel perforation. Further evaluation confirmed that her symptoms were attributed to Clostridium perfringens-related gas gangrene. Despite immediate surgical intervention, the patient succumbed to her disease. Clostridial gas gangrene is associated with an extremely high mortality rate. Therefore, accurate detection and prompt management are indispensable to ensuring a favorable patient outcome.

Other symptoms included pain, blurred vision and excessive yellowish-white discharge from both eyes. There was a history of multiple sexual partners. The patient was assessed with bilateral perforated corneal ulcer due to gonococcal infection, based on the findings of intracellular and extracellular Gram-negative diplococci found on the Gram staining examination. The cornea in both eyes showed perforation with iris prolapse inferiorly. The perforations were treated with temporary periosteal grafts. The grafts remained in place after the surgery. Final uncorrected visual acuity was 6/20 in the right eye and 6/24 in the left eye, a few months after surgery.

  8. Measurement of hearing loss due to perforated tympanic membrane using image processing techniques

    The tympanic membrane (ear drum) is a thin tissue film that is stretched between the outer and middle ear. Sound waves travel from outside the ear, and strike the tympanic membrane resulting in its vibration. These vibrations amplify the sound waves and transmit them to the ossicles (auditory bones). The magnitude of amplification is directly proportional to vibrating area of tympanic membrane. Hence a perforation in this membrane would result in hearing loss. Pure-tone audiometry is the traditional procedure used to detect the amount of hearing loss in a patient. However, it is lengthy and less efficient, as it largely depends on the response of the patient to sound intensity and frequency of pure-tones. We present a relatively more efficient approach to determine hearing loss due to perforated tympanic membrane using image processing techniques. We describe an algorithm that uses unsharp masking to sharpen images of the perforations as well as the tympanic membrane. Then, it converts the image into a binary image using thresholding. A median filter is applied to get rid of the noise component in the image. The ratio of the area of perforation and total area of tympanic membrane will define the percentage of hearing loss. Our approach will eliminate the error introduced due to patient dependency as in the traditional method.

    The authors report the case of 14-year-old girl with a history of myelomeningocele and previously shunt-treated hydrocephalus who presented with right-sided abdominal pain and subcutaneous emphysema that developed over a 1-week period. A CT scan of the patient's abdomen revealed a retained distal ventriculoperitoneal (VP) catheter with air tracking from the catheter to the upper chest wall. Given the high suspicion of the catheter being intraluminal, an exploratory laparotomy was performed and revealed multiple jejunal perforations. The patient required a partial small-bowel resection and reanastomosis for complete removal of the retained catheter. Six other similar cases of bowel perforation occurring in patients with abandoned VP and subdural-peritoneal shunts have been reported. The authors analyzed these cases with regard to age of presentation, symptomatic presentation, management, morbidity, and mortality. While there was 0% mortality associated with bowel perforation secondary to a retained distal VP catheter, the morbidity was significantly high and included peritonitis and small bowel resection.

    Nasal foreign bodies are common in children. Button batteries deserve particular interest due to the severity and precocity of the injuries they cause. The button battery represents a growing danger. Its small size and brilliant appearance make them attractive to children, often being introduced in the nose, ear or mouth. It is imperative that the community and physicians are aware of the risks it poses. Early diagnosis and immediate removal is essential. Their delay can lead to necrosis of the nasal mucosa and septal perforation. We report 10 cases of septal perforation due to button battery. We emphasize the dangers of nasal impaction and the need for quick removal to avoid long-term complications.

    This case report describes a 27-week, 1040-g infant, whose mother presented with an acute abruption and fetal distress prompting emergency cesarean birth. The birth was further complicated by fetal malposition, manual version, birth trauma, and perinatal depression requiring intubation, ventilation, and chest compressions. On day of life (DOL) 7, the infant suddenly deteriorated with cardiovascular collapse and severe coagulopathy. Coexisting spontaneous bowel perforation (SBP) and ruptured subcapsular liver hematoma (SLH) were confirmed operatively. Although survival with ruptured SLH is rarely reported, with aggressive medical and surgical management, this infant survived and was discharged home at 43 weeks postconceptual age. SBP may occur silently; pneumoperitoneum may be an incidental finding. Conversely, rupture of an SLH typically presents with a sudden clinical deterioration. The common predisposing factor for both conditions is low birth weight (LBW). A review of the known and proposed risk factors, clinical signs and symptoms, pathophysiology, and treatment of both SBP and SLH are provided. A literature review highlighting the potential impact of drug exposures (indomethacin, hydrocortisone, and low molecular weight heparin) is provided, along with a discussion of the implications for clinical practice and research.

    Few cases of clostridial gas gangrene associated with uterine malignancy have been reported. We report on a 46-year-old woman with clostridial sepsis. On the day of admission due to severe abdominal pain, peritonitis was diagnosed, and computed tomography showed free air in the abdomen. At emergency laparotomy, perforation of the necrotic uterine wall was observed. During hysterectomy, septic shock developed, and life-saving therapy was performed in the intensive care unit after surgery. Pathological examination of the necrotic uterine wall showed grade III endometrial adenocarcinoma of the uterine endometrium (International Federation of Gynecology and Obstetrics stage IIIa) with gas gangrene due to Clostridium perfringens. This report aims to alert gynecologists to the possibility that clostridial gas gangrene of the uterus can occur in patients with peritonitis and intra-abdominal free air. Early recognition and aggressive therapy can save patients' lives.

    Background and Objectives: Meckel's diverticulum is a common anomaly of the gastrointestinal tract that may result in gastrointestinal bleeding, diverticulitis, and small bowel obstruction. This report describes the use of laparoscopy to treat a rare complication of Meckel's diverticulum–small bowel obstruction due to phytobezoar impaction. More generally, it provides an example of the feasibility and utility of a laparoscopic approach to small bowel obstructions of unknown causes. Methods: A 34-year-old male presented to the emergency department complaining of episodic abdominal pain and vomiting. He had no history of abdominal surgery. His vital signs were stable, and his abdomen was distended, but only mildly tender. He had no abdominal wall hernias on examination. Imaging was consistent with small bowel obstruction. He was brought to the operating room where laparoscopy revealed a Meckel's diverticulum with an impacted phytobezoar as the source of obstruction. The diverticulum was resected and the phytobezoar removed laparoscopically. Results: The patient recovered well and was discharged home on the third postoperative day, tolerating a regular diet. Conclusions: Phytobezoar impaction in a Meckel's diverticulum causing small bowel obstruction is a rare event. It can be effectively treated laparoscopically. This case provides an example of the potential utility of laparoscopy in treating small bowel obstructions of unclear etiology. PMID:22643518

    Patient: Female, 42 Final Diagnosis: Spontaneous pelvic-abdominal peritonitis due to actinomyces Symptoms: Abdominal distension • abdominal pain • acute abdomen • fever • intermenstrual bleeding • nausea • sepsis • septic shock Medication: — Clinical Procedure: — Specialty: Surgery Objective: Unusual clinical course Background: Pelvic-abdominal actinomycosis is a rare chronic condition caused by an anaerobic, gram-negative rod-shaped commensal bacterium of the Actinomyces species. When Actinomyces becomes pathogenic, it frequently causes a chronic infection with granulomatous abscess formation with pus. Due to diversity in clinical and radiological presentation, actinomycosis can easily be mistaken for several other conditions. Peritonitis without preceding abscess formation caused by Actinomyces species has been described in only few cases before in literature. Case report: We report a case of spontaneous pelvic-abdominal peritonitis with presence of pneumoperitoneum and absence of preceding abscesses due to acute actinomycosis mimicking a perforation of the proximal jejunum in a 42-year-old female with an intra-uterine contraceptive device in place. Explorative laparotomy revealed 2 liters of odorless pus but no etiological explanation for the peritonitis. The intra-uterine contraceptive device was removed. Cultivation showed growth of Actinomyces turicensis. The patient was successfully treated with penicillin. Conclusions: In the case of primary bacterial peritonitis or lower abdominal pain without focus in a patient with an intrauterine device in situ, Actinomyces should be considered as a pathogen.

    The authors report a case of a 2-year-old boy with postinfectious hydrocephalus, managed with a ventriculoperitoneal (VP) shunt and complicated by shunt extrusion through the cranial skin. The shunt was removed due to concern for infection, and the child was found to have an enterocutaneous fistula (ECF) communicating along the shunt track between the small bowel and a clavicular sinus. Self-closure of the ECF was anticipated. Thus, the fistula was managed expectantly with dressing changes of the clavicular sinus, while the patient's malnutrition was managed in accordance with World Health Organization protocols. The presentation, prognosis and management of ECFs, including the likelihood of self-resolution and the role of expectant management, are discussed. Additionally, proposed mechanisms of ECF formation in the setting of a VP shunt are discussed, with an emphasis on the roles of infection and malnutrition.

    Purpose: To describe a case of chronic graft versus host disease (GVHD) leading to severe dry eye and recurrent corneal perforation in both eyes, its stepwise management and histopathological reports. Case Report: A 22-year-old woman with a history of thalassemia and subsequent high-dose chemotherapy followed by allogeneic bone marrow transplant (BMT) was referred to Farabi Eye Hospital. Despite aggressive medical and surgical intervention, corneal vascularization in her right eye progressed and led to corneal perforation. Cyanoacrylate glue was applied to seal the perforation, however it recurred. Multilayer amniotic membrane transplantation (AMT) was performed to seal the corneal perforation, which was effective for a short period. Subsequently, the corneal perforation recurred and penetrating keratoplasty was performed. After a few months deep vascularization and descemetocele occurred in the fellow left eye and the patient finally underwent therapeutic lamellar keratoplasty. Conclusion: Patients with GVHD are at risk of severe dry eye and subsequent corneal vascularization. Recurrent and recalcitrant corneal perforation resistant to cyanoacrylate glue and multilayer AMT may occur. Proper systemic and ocular management alongside close collaboration with the hematologist is strongly recommended to control the condition. PMID:27195094

    Objectives. Endoscopic resection (ER) is commonly performed to treat gastric epithelial neoplasms and subepithelial tumors. The aim of this study was to predict the risk factors for surgery after ER-induced perforation. Methods. We retrospectively reviewed the data on patients who received gastric endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) between January 2010 and March 2015. Patients who were confirmed to have perforation were classified into surgery and nonsurgery groups. We aimed to determine the risk factors for surgery in patients who developed iatrogenic gastric perforations. Results. A total of 1183 patients underwent ER. Perforation occurred in 69 (5.8%) patients, and 9 patients (0.8%) required surgery to manage the perforation. In univariate analysis, anterior location of the lesion, a subepithelial lesion, two or more postprocedure pain killers within 24 hrs, and increased heart rate within 24 hrs after the procedure were the factors related to surgery. In logistic regression analysis, the location of the lesion at the anterior wall and using two or more postprocedure pain killers within 24 hrs were risk factors for surgery. Conclusion. Most cases of perforations after ER can be managed conservatively. When a patient requires two or more postprocedure pain killers within 24 hrs and the lesion is located on the anterior wall, early surgery should be considered instead of conservative management.

    We report an exceptional case of a 7 year-old patient with necrotic small bowel volvulus due to adult ascaris lumbricoides. At the admission, the child had intestinal obstruction evolving since two days with alteration of general state. Abdominal radiography without preparation showed small bowel air-fluid levels and tiger-stripe appearance evoking the diagnosis of acute intestinal obstruction associated with abdominal mass. After resuscitation, the surgical treatment consisted of laparotomy which showed necrotic volvulus of the terminal ileum containing adult ascaris lumbricoides. The patient underwent small bowel resection, approximately one meter of affected section was removed and then an ileostomy was performed. The evolution was favorable. The patient underwent ileorectal anastomosis four weeks later. After a 2 year follow-up period the child had no symptoms.

    Non hepatic origin of refractory ascites is not a rarity. Hemolytic anemias are known to cause inspissated bile and biliary obstruction. Distal biliary obstruction can lead to biliary perforation. The authors report a case of hereditary spherocytosis leading to inspissated bile causing bile duct perforation and biliary ascites. A high index of suspicion for biliary ascites should be kept in a child with refractory ascites in the setting of progressive ascites with decreasing bilirubin. Ascitic fluid bilirubin analysis will clinch the diagnosis. Surgical repair is the optimal management.

    Introduction Ingestion of foreign bodies has been previously reported in some patients with schizophrenia. This behavior may be a manifestation of delusional beliefs or a response to command hallucinations and can lead to severe complications. Case Presentation This paper reports a patient with schizophrenia who, as a manifestation of his illness, ingested a metallic skewer to kill ademon inside his abdomen that he believed was controlling him. As a result, he developed an acute intestinal perforation and underwent surgery. Conclusions It is of a great importance to closely monitor the therapy compliance of patients suffering from mental illnesses. This will benefit them by preventing some of the serious complications of their disease, which may include life-threatening conditions such as intestinal perforation that needs surgical intervention.

    Ante mortem cases of venous thrombosis in patients with nonbacterial thrombotic endocarditis (NBTE) have not yet been reported. We describe a rare case of NBTE in a patient with mesenteric vein thrombosis. A healthy 37-year-old man with abdominal pain and fever underwent emergency small bowel resection due to bowel ischemia resulting from mesenteric vein thrombosis. Transthoracic echocardiography revealed multiple mobile masses attached to the anterior leaflet of the mitral valves and their chordae tendineae. On suspicion of infective endocarditis, the cardiac masses were excised through open-heart surgery. However, pathologic reviews were compatible with NBTE. The patient was stable after the cardiac surgery and was treated with warfarin. Laboratory and imaging findings regarding his hypercoagulable condition were all negative. PMID:24876861

    Small bowel obstructions (SBOs) are a known perioperative complication of laparoscopic Roux-en-Y gastric bypass and common etiologies include internal hernia, port site hernia, jejunojejunostomy stricture, ileus and adhesions. Less commonly, SBO can be caused by superior mesenteric artery syndrome, intussusception and intraluminal blood clot. We present a case of SBO caused by intraluminal blood clot from jejunojejunostomy staple line bleeding in a patient with a normal coagulation profile. Computed tomography was used to elucidate the cause of perioperative SBO, and diagnostic laparoscopy was used to both diagnose and treat the complication. In this case, the intraluminal clot was evacuated laparoscopically by enterotomy, thrombectomy and primary closure without anastomotic revision since there was no evidence of continued bleeding. Administration of enoxaparin and Toradol post-operatively may have exacerbated mild intraluminal bleeding occurring at the stapled jejunojejunal anastomosis. Prompt recognition and treatment of perioperative SBO can prevent catastrophic consequences related to bowel perforation. PMID:27554828

    Coronary artery bypass graft perforation during percutaneous coronary intervention is a rare complication. Perforation of a left internal mammary artery (LIMA) graft due to a guide catheter extension system has not been described. We report the successful deployment of a polytetrafluoroethylene (PTFE)-covered stent to seal the LIMA graft perforation due to the guide catheter extension system. Percutaneous coronary intervention was performed for a culprit lesion of the distal left circumflex via the LIMA graft. A balloon catheter failed to be delivered because the LIMA graft was very long and tortuous. The guide catheter extension system was introduced, and the balloon was delivered and inflated. However, the LIMA graft perforation with continuous extravasation was caused by the edge of deeper intubated guide extension catheter when a coronary stent was attempted to be delivered to the culprit lesion. A long balloon inflation was performed, but the perforation was not completely sealed. The PTFE-covered stent was successfully deployed and sealed the LIMA graft perforation. This case describes that the rapid deployment of PTFE-covered stent is effective to treat severe coronary artery bypass graft perforation due to the guide catheter extension system.

    Small bowel obstruction and large bowel obstruction account for approximately 20% of cases of acute abdominal surgical conditions. The role of the radiologist is to answer several key questions: Is obstruction present? What is the level of the obstruction? What is the cause of the obstruction? What is the severity of the obstruction? Is the obstruction simple or closed loop? Is strangulation, ischemia, or perforation present? In this presentation, the radiologic approach to and imaging findings of patients with known or suspected bowel obstruction are presented.

    Iatrogenic intestinal perforations in orthopaedic surgery are very rare. Reports of iatrogenic lesions caused by a guide wire during femur fracture osteosynthesis are even scarcer. There are no similar reports in recent literature. As opposed to what is normally described the lesion documented in this case report was not identified on time resulting in death by peritonitis. The forensic autopsy allowed the identification of an intestinal perforation with faecal leakage to peritoneal space in association with a vesical perforation enabling the reproduction of the guide wire path. In view of the increasing number of osteosynthesis it is essential for the surgeon to be aware of possible complications due to guide wire perforations. Cases like this go unnoticed if the forensic pathologist is not familiarized with the surgical technique which may explain the rarity of such descriptions in literature.

    Gallbladder perforation (GBP) represents a rare, but potentially life-threatening, complication of acute cholecystitis. GBP is subdivided into three categories whereas the development of biloma is extremely rare. The present case study reports on a 40-year-old man with a 10-year history of calculus cholecystitis, who was referred to The First Affiliated Hospital of Nanjing Medical University (Nanjing, China) for the surgical treatment of an emerging massive hepatic entity with insidious symptoms and normal laboratory tests. A preoperative imaging study demonstrated the collection with internal septations and mural nodules, but no visible communication with the biliary system. Given the suspected biliary cystic tumor, a laparotomy was performed and the lumen was scattered with papillae. An intraoperative frozen section examination illustrated a simple hepatic cyst. Biochemical analysis of the collection and histopathology of the gallbladder and capsule substantiated the diagnosis of biloma formation due to GBP. The purpose of the present case report was to demonstrate how a pinhole-sized perforation with extravasation of unconcentrated bile from the gallbladder may result in insidious clinical presentation and an undetected leak site. According to the clinicopathological characteristics and composition, formation of biloma should be classified as type IV GBP. To differentiate bilomas with intracystic septations and mural nodules from BCTs is difficult via a preoperative examination, and the definitive diagnosis should be based on a histological examination. Laparotomy with frozen section examination may be the optimal approach in such a case. PMID:28123732

    Gallstone ileus is an uncommon complication of cholelithiasis. Most patients affected by gallstone ileus are elderly and have multiple comorbidities. Symptoms are vague and insidious, which may delay the correct diagnosis for days. Here we are reporting an uncommon complication of gallstone ileus. We report on a 70-year-old man with small bowel obstruction at the jejunum due to an impacted stone, which led to necrosis and perforation of the proximal bowel wall. Laparoscope-assisted small bowel resection with enterolithotomy was used to successfully treat the patient's perforation and obstruction. His recovery was uneventful. Gallstone ileus commonly presents with bowel obstruction, but intestinal perforation occurs very rarely. A laparoscopic approach can provide both diagnostic and therapeutic roles in management.

    Productivity can be increased by prepacking perforations with gravel before a major gravel pack is pumped. The main gravel-pack treatment follows immediately after the prepack. This procedure can increase perforation permeability due to a more complete gravel fill of the perforation. The gravel pack prevents perforations from collapsing or filling with formation sand.

    Ogilvie syndrome or acute colonic pseudo-obstruction is characterized by acute dilatation of the colon usually involving caecum and right hemi-colon in the absence of any mechanical obstruction. It is usually associated with an underlying severe illness/infection or surgery, mostly caesarean section and rarely occurs spontaneously. Identification of this condition is important due to the increased risk of bowel ischaemia and perforation particularly with caecal diameter >9 cm. This is a case report of bowel perforation following caesarean section leading to urgent laparotomy. PMID:27554827

    Patient awareness and concern regarding the potential health risks from ionizing radiation have peaked recently (Coakley et al., 2011) following widespread press and media coverage of the projected cancer risks from the increasing use of computed tomography (CT) (Berrington et al., 2007). The typical young and educated patient with inflammatory bowel disease (IBD) may in particular be conscious of his/her exposure to ionising radiation as a result of diagnostic imaging. Cumulative effective doses (CEDs) in patients with IBD have been reported as being high and are rising, primarily due to the more widespread and repeated use of CT (Desmond et al., 2008). Radiologists, technologists, and referring physicians have a responsibility to firstly counsel their patients accurately regarding the actual risks of ionizing radiation exposure; secondly to limit the use of those imaging modalities which involve ionising radiation to clinical situations where they are likely to change management; thirdly to ensure that a diagnostic quality imaging examination is acquired with lowest possible radiation exposure. In this paper, we synopsize available evidence related to radiation exposure and risk and we report advances in low-dose CT technology and examine the role for alternative imaging modalities such as ultrasonography or magnetic resonance imaging which avoid radiation exposure.

    2015-01-01

    Introduction Bezoar is an unusual cause of small bowel obstruction accounting for 0.4–4% of all mechanical bowel obstruction. The common site of obstruction is terminal ileum. Case report A 28-year-old male with no past surgical history, known to have severe mental retardation presented with anorexia. CT scan demonstrated dilated small bowel loops and intraluminal ileal mass with mottled appearance. At exploratory laparotomy, a bezoar was found impacted in the terminal ileum 5–6 inches away from the ileocecal valve and was removed through an enterotomy. Discussion Bezoars are concretions of fibers or foreign bodies in the alimentary tract. Small bowel obstruction is one of common clinical symptoms. The typical finding of well-defined intraluminal mass with mottled gas pattern in CT scan is suggestive of an intestinal bezoar. The treatment option of bezoar is surgery including manual fragmentation of bezoar and pushing it toward cecum, enterotomy or segmental bowel resection. Thorough exploration of abdominal cavity should be done to exclude the presence of concomitant bezoars. Recurrence is common unless underlying predisposing condition is corrected. Conclusions Bezoar-induced small bowel obstruction remains an uncommon diagnosis. It should be suspected in patients with an increased risk of bezoar formation, such as in the presence of previous gastric surgery, a history suggestive of increased fiber intake, or patient with psychiatric disorders. CT scan is helpful for preoperative diagnosis. PMID:26764889

  3. Arterial hypertension due to fructose ingestion: model based on intermittent osmotic fluid trapping in the small bowel

    PubMed Central

    2010-01-01

    Based on recently reported data that fructose ingestion is linked to arterial hypertension, a model of regulatory loops involving the colon role in maintenance of fluid and sodium homeostasis is proposed. In normal digestion of hyperosmolar fluids, also in cases of postprandial hypotension and in patients having the "dumping" syndrome after gastric surgery, any hyperosmolar intestinal content is diluted by water taken from circulation and being trapped in the bowel until reabsorption. High fructose corn sirup (HFCS) soft drinks are among common hyperosmolar drinks. Fructose is slowly absorbed through passive carrier-mediated facilitated diffusion, along the entire small bowel, thus preventing absorption of the trapped water for several hours. Here presented interpretation is that ingestion of hyperosmolar HFCS drinks due to a transient fluid shift into the small bowel increases renin secretion and sympathetic activity, leading to rise in ADH and aldosterone secretions. Their actions spare water and sodium in the large bowel and kidneys. Alteration of colon absorption due to hormone exposure depends on cell renewal and takes days to develop, so the momentary capacity of sodium absorption in the colon depends on the average aldosterone and ADH exposure during few previous days. This inertia in modulation of the colon function can make an individual that often takes HFCS drinks prone to sodium retention, until a new balance is reached with an expanded ECF pool and arterial hypertension. In individuals with impaired fructose absorption, even a higher risk of arterial hypertension can be expected. PMID:20579372

    Background Necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) are acute intestinal conditions which could result in mortality and severe morbidity in preterm infants. Our objective was to identify dysregulated micro-RNAs (miRNAs) in small bowel tissues of NEC and SIP, and their possible roles in disease pathophysiology. Methods We performed differential miRNA arrays on tissues of NEC (n = 4), SIP (n = 4) and surgical-control (Surg-CTL; n = 4), and validated target miRNAs by qPCR (n = 10 each group). The association of target miRNAs with 52 dysregulated mRNAs was investigated by bioinformatics on functional and base-pair sequence algorithms, and correlation in same tissue samples. Results We presented the first miRNA profiles of NEC, SIP and Surg-CTL intestinal tissues in preterm infants. Of 28 validated miRNAs, 21 were significantly different between NEC or SIP and Surg-CTL. Limited overlapping in the aberrant expression of miRNAs between NEC and SIP indicated their distinct molecular mechanisms. A proposed network of dysregulated miRNA/mRNA pairs in NEC suggested interaction at bacterial receptor TLR4 (miR-31, miR-451, miR-203, miR-4793-3p), mediated via key transcription factors NFKB2 (miR-203), AP-1/FOSL1 (miR-194-3p), FOXA1 (miR-21-3p, miR-431 and miR-1290) and HIF1A (miR-31), and extended downstream to pathways of angiogenesis, arginine metabolism, cell adhesion and chemotaxis, extracellular matrix remodeling, hypoxia/oxidative stress, inflammation and muscle contraction. In contrast, upregulation of miR-451 and miR-223 in SIP suggested modulation of G-protein-mediated muscle contraction. Conclusions The robust response of miRNA dysregulation in NEC and SIP, and concerted involvement of specific miRNAs in the molecular networks indicated their crucial roles in mucosa integrity and disease pathophysiology.

    Meckel’s diverticulum (MD) is a persistent remnant of the vitelointestinal duct and is present in 2% of population [1]. It is the most common congenital malformation of the gastrointestinal tract. It can present clinically as haemorrhage, diverticulitis, intussusception, chronic ulceration, intestinal obstruction and perforation. Complicated presentation, especially bleeding, tends to be more common in the paediatric group, whereas intestinal obstruction is more common in adults [2]. Patients with a perforation of Meckel’s diverticulum by an enterolith are rare and may present with right iliac fossa pain, which mimics acute appendicitis. PMID:26363105

    Bowel perforation is a rare complication of laparoscopic cholecystectomy, which if left undiagnosed can have fatal consequences. In addition, isolated small bowel perforation is extremely rare and should be considered in patients presenting with sudden onset abdominal pain in the postoperative period. A 57-year-old male with symptomatic gallstones underwent urgent laparoscopic cholecystectomy and was discharged home on postoperative day (POD) 1 without complications. He presented to the emergency department on POD 11 complaining of sudden onset abdominal pain. A CT scan did not confirm a diagnosis and he was admitted for observation. On post admission day 2, he became significantly peritonitic and laparotomy revealed jejunal perforation. Bowel resection with hand-sewn anastomosis was completed and he was discharged on POD 10. Follow-up at 6 weeks revealed no further issues. We review the literature on small bowel perforation post laparoscopic cholecystectomy. PMID:26908534

We report a case of a 53 year-old male, with no history of travel abroad, who was admitted to hospital with haematochezia. A tumor of the rectum was diagnosed clinically. Due to acute intestinal obstruction, laparotomy was performed, revealing multiple perforations of the large bowel and severe peritonitis leading to subtotal colectomy. The histological examinations revealed transmural amoebic colitis. The patient died due to multi-organ failure.

    Improvements in radiologic localization have made percutaneous catheter drainage (PCD) the initial procedure of choice for many intra-abdominal abscesses (IAA). During the past seven years 154 patients underwent PCD for treatment of abdominal abscesses. Fourteen of these patients had PCD as the initial treatment for IAA secondary to a perforated viscus and subsequently underwent an elective one-stage operation to treat the underlying disease. Etiologies of the abscesses included perforated appendicitis in six patients, sigmoid diverticulitis in three patients, Crohn's ileitis in two patients, and one case each of perforated gastric ulcer, perforated sigmoid carcinoma, and perforated gallbladder. Initial localization of the abscess was achieved by either CT or ultrasound. Seven abscesses were localized in the right lower quadrant, four were localized in the liver, and one was localized each in the left flank, right flank, subhepatic space, and pelvis. All patients subsequently underwent a definitive elective operation for their primary disease including six interval appendectomies, four sigmoid colectomies, two small-bowel resections, one subtotal gastrectomy and one cholecystectomy. There were no complications due to PCD and no deaths occurred. We conclude that PCD can be successfully performed as the initial treatment for IAA associated with a perforated viscus, obviating the first stage of the traditional two-stage surgical approach.

    The co-existence of acquired immune deficiency syndrome (AIDS) and tuberculosis is a major cause of morbidity and mortality because of a widespread organ involvement. The gastrointestinal tract is a common site for localization of opportunistic microorganisms in AIDS. However, surgical abdominal emergencies such as intestinal perforation resulted from tuberculosis are uncommon in these patients. The asymptomatic occurrence of such intestinal perforation has not been reported our knowledge. We represent an HIV and HCV co-infected man with miliary tuberculosis and an incidentally detected free air under  diaphragm in the chest X-ray eventually resulting in exploratory laparotomy which then revealed two tubercular-induced intestinal perforations. It seems that as the tuberculosis is increasing in incidence, mostly due to reactivation in HIV-infected patients especially in developing countries, we should not underestimate its acute abdominal emergencies such as bowel perforation.

    Purpose To report corneal stem cell allografts in a patient with a persistent epithelial defect as well as corneal melting and perforation due to severe ultraviolet light burn and thermokeratoplasty treatment for keratoconus. Methods A 21-year-old female patient with corneal melting, perforation and a persistent epithelial defect in her left eye secondary to iatrogenic treatment for keratoconus, thermokeratoplasty and cross-linking was treated with penetrating keratoplasty, using a 9.0-mm diameter corneal graft and limbal stem cell allograft implants. At the end of the procedure, subtenonian injections of a combination of bevacizumab and triamcinolone were given. Results The patient had a favorable outcome 48 h after surgery, with an improvement of symptoms and a complete corneal healing. By the third week after surgery, she had a best-corrected visual acuity of 20/60 and a clear corneal graft, which remained stable for the 9 months of follow-up. Conclusions Treatment with limbal stem cell allografts and penetrating keratoplasty in a female patient with a large corneal defect and melting in her left eye was effective. Larger studies are warranted to explore the real impact of this procedure. PMID:23185178

    A rare but severe complication, intestinal necrosis, has been reported after sodium polystyrene sulfonate (SPS; Kayexalate) and sorbitol intake. Some case reports described bowel perforation following calcium polystyrene sulfonate (CPS; Kalimate) administration. We report a case of ileum and colon perforation following peritoneal dialysis-related peritonitis and high-dose Kalimate in a 59-year-old female patient. The patient had a history of hypertension, diabetes mellitus, and end-stage renal disease (ESRD). During hospitalization for peritoneal dialysis-related peritonitis, she developed hyperkalemia, and Kalimate was administered orally. However, severe abdominal distension and pain occurred just one day after Kalimate intake. An urgent surgery disclosed several perforations in the ileum and sigmoid colon. Pathology of the resected gut showed transmural necrosis and perforation with basophilic angulated crystals. The patient finally expired during hospitalization due to refractory septic shock.

    The main cause of perforation of the gallbladder is cholecystitis with or without cholelithiasis. In old age, spontaneous perforation of gallbladder can be due to decrease in its blood supply, which can be due to atherosclerosis, focal vasospasm or localized vasculitis. Perforation of gallbladder is associated with high morbidity and mortality, if left untreated. Here we report a case of a 60-year-old male with perforation of gallbladder. PMID:27785327

    Abstract Colorectal perforation has a high rate of mortality. We compared the incidence and fatality rates of colorectal perforation among different hospitals in Japan using data from the nationwide surgical database. Patients were registered in the National Clinical Database (NCD) between January 1st, 2011 and December 31st, 2013. Patients with colorectal perforation were identified from surgery records by examining if acute diffuse peritonitis (ADP) and diseases associated with a high probability of colorectal perforation were noted. The primary outcome measures included the 30-day postsurgery mortality and surgical mortality of colorectal perforation. We analyzed differences in the observed-to-expected mortality (O/E) ratio between the two groups of hospitals, that is, specialized and non-specialized, using the logistic regression analysis forward selection method. There were 10,090 cases of disease-induced colorectal perforation during the study period. The annual average postoperative fatality rate was 11.36%. There were 3884 patients in the specialized hospital group and 6206 in the non-specialized hospital group. The O/E ratio (0.9106) was significantly lower in the specialized hospital group than in the non-specialized hospital group (1.0704). The experience level of hospitals in treating cases of colorectal perforation negatively correlated with the O/E ratio. We conducted the first study investigating differences among hospitals with respect to their fatality rate of colorectal perforation on the basis of data from a nationwide database. Our data suggest that patients with colorectal perforation should choose to be treated at a specialized hospital or a hospital that treats five or more cases of colorectal perforation per year. The results of this study indicate that specialized hospitals may provide higher quality medical care, which in turn proves that government policy on healthcare is effective at improving the medical system in Japan.

    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.

    Blast injuries are rare, and although blast-induced perforations of the bowel have been described in the past, the entity of a delayed perforation caused by an evolving injury has not been reported. We report three men injured by the explosion of a terrorist bombing in open air. They suffered primary blast injuries, which resulted in isolated perforations of the terminal ileum. They were operated at different times after the blast event. The resected specimens were examined under light microscopy. One patient was operated immediately, and had three perforations in the terminal ileum. In the other two patients, abdominal complaints appeared only 24 and 48 hours later. These two patients were found to have hematomas in the wall of the terminal ileum, and small perforations therein, with almost no contamination of the peritoneal cavity. On histological examination, there were small perforations with disruption of all intestinal layers. In the vicinity of the perforations, the mucosa was necrotic and disorganized. The submucosa showed edema and vascular thrombi, and at several points mucus was shown dissecting through the muscularis propria, thus creating minute microperforations. Because of the findings in these patients, we suggest a mechanism of evolving damage to the bowel wall and delayed perforation rather than delayed diagnosis, after blast injuries. We suggest that patients exposed to a significant blast should be watched carefully for at least 48 hours.

    Checkpoint inhibitors blocking CTLA-4 (ipilimumab) and PD-1 (nivolumab, pembrolizumab) have transfigured our cancer treatment paradigm. However, these drugs can induce immune-related adverse events that share clinical and pathological characteristics with immune-mediated diseases. One of the most severe immune-related adverse event observed with anti-CTLA-4 is an enterocolitis that mirrors naturally occurring inflammatory bowel disease. This paper reviews the clinical, immunological, and microbiota data associated with the immune-related enterocolitis induced by the cancer immunotherapy blocking CTLA-4, ipilimumab. A parallel analysis of the mechanisms underlying inflammatory bowel diseases on the one hand, and anti-CTLA-4-induced colitis on the other hand, stresses the crucial role of the gut microbiota and of resident Treg in the genesis of both iatrogenic and spontaneous inflammatory bowel diseases.

    BACKGROUND: To evaluate the relation between non-steroidal anti-inflammatory drugs (NSAIDs) and colitis due to inflammatory bowel disease. METHODS: A case-control study was conducted using a prospectively constructed, record linkage database containing hospital event and dispensed drug data (1989-93). The study population consisted of 319,465 people resident in Tayside in January 1989, and still resident (or dead) in October 1994. RESULTS: Of the 785 patients admitted to hospital as emergencies with colitis between July 1989 and June 1993, 200 fulfilled the case criterion of colitis due to inflammatory bowel disease. A further 1198 persons were used as community controls. Odds ratios were calculated for three exposure periods (current, recent, and past exposure). The overall odds ratios (with 95% confidence intervals) for current and recent exposure to NSAIDs were 1.77 (1.01 to 3.10) and 1.93 (1.20 to 3.09) respectively. Current and recent exposure to NSAIDs was also associated for incident cases, with odds ratios of 2.96 (1.32 to 6.64) and 2.51 (1.13 to 5.55). There was a trend for recent exposure among non-incident cases. CONCLUSION: The use of NSAIDs may be associated with an increased risk of emergency admission to hospital for colitis due to inflammatory bowel disease, particularly among patients with no previous history.

    ABSTRACT Objective To characterize the pattern of primary small bowel cancers in a tertiary East-European hospital. Methods A retrospective study of patients with small bowel cancers admitted to a tertiary emergency center, over the past 15 years. Results There were 57 patients with small bowel cancer, representing 0.039% of admissions and 0.059% of laparotomies. There were 37 (64.9%) men, mean age of 58 years; and 72 years for females. Out of 57 patients, 48 (84.2%) were admitted due to an emergency situation: obstruction in 21 (38.9%), perforation in 17 (31.5%), upper gastrointestinal bleeding in 8 (14.8%), and lower gastrointestinal bleeding in 2 (3.7%). There were 10 (17.5%) duodenal tumors, 21 (36.8%) jejunal tumors and 26 (45.6%) ileal tumors. The most frequent neoplasms were gastrointestinal stromal tumor in 24 patients (42.1%), adenocarcinoma in 19 (33.3%), lymphoma in 8 (14%), and carcinoids in 2 (3.5%). The prevalence of duodenal adenocarcinoma was 14.55 times greater than that of the small bowel, and the prevalence of duodenal stromal tumors was 1.818 time greater than that of the small bowel. Obstruction was the complication in adenocarcinoma in 57.9% of cases, and perforation was the major local complication (47.8%) in stromal tumors. Conclusion Primary small bowel cancers are usually diagnosed at advanced stages, and revealed by a local complication of the tumor. Their surgical management in emergency setting is associated to significant morbidity and mortality rates. PMID:26676271

    Endoscopically placed biliary stents are a well-established procedure for the treatment of benign and malignant causes of obstructive jaundice. A plastic stent is usually inserted in patients with obstructive jaundice due to pancreatic cancer as a short-term procedure. Stent migration has been reported as a complication, although in most cases the stent will pass through or remain in the bowel lumen for a period of time. In rare cases, the stent may cause sigmoid perforation and pelvic abscess formation, especially in patients with sigmoid diverticulae or abdominal adhesions due to previous surgery. We present a patient with sigmoid perforation and pelvic abscess due to distal migration of a biliary stent placed to decompress a pancreatic head carcinoma. PMID:25870211

    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.

    Peptic ulcer disease (PUD) affects 4 million people worldwide annually. The incidence of PUD has been estimated at around 1.5% to 3%. Perforated peptic ulcer (PPU) is a serious complication of PUD and patients with PPU often present with acute abdomen that carries high risk for morbidity and mortality. The lifetime prevalence of perforation in patients with PUD is about 5%. PPU carries a mortality ranging from 1.3% to 20%. Thirty-day mortality rate reaching 20% and 90-d mortality rate of up to 30% have been reported. In this review we have summarized the current evidence on PPU to update readers. This literature review includes the most updated information such as common causes, clinical features, diagnostic methods, non-operative and operative management, post-operative complications and different scoring systems of PPU. With the advancement of medical technology, PUD can now be treated with medications instead of elective surgery. The classic triad of sudden onset of abdominal pain, tachycardia and abdominal rigidity is the hallmark of PPU. Erect chest radiograph may miss 15% of cases with air under the diaphragm in patients with bowel perforation. Early diagnosis, prompt resuscitation and urgent surgical intervention are essential to improve outcomes. Exploratory laparotomy and omental patch repair remains the gold standard. Laparoscopic surgery should be considered when expertise is available. Gastrectomy is recommended in patients with large or malignant ulcer. PMID:28138363

    Case series Patients: Male, 33 • Male, 18 • Male, 19 Final Diagnosis: Congenital band causing a small bowel obstruction Symptoms: Progressive abdominal pain that eventually becomes excessive Medication: — Clinical Procedure: Laparoscopic band removal Specialty: Surgery Objective: Rare disease Background: Among the causes of constipation are bands and adhesions that lead to obstructions at different points in the intestinal tract. These can occur as a consequence of healing following surgery or trauma. However, an entity known as congenital band exists where a band is present from birth. Here we report three such cases of adults with symptoms of intestinal obstruction, in whom a congenital band was discovered through exploratory laparoscopy. Case Reports: All three of these patients presented lacking a history of any abdominal trauma or previous abdominal surgeries, a fact that is often used to exclude an adhesion as a differential. All three recovered quickly and had relief of their symptoms following surgical intervention. Conclusions: Bands and adhesions are common surgical causes of small bowel obstruction, leading to symptoms such as nausea, vomiting, constipation, and obstipation. These bands almost always result from a prior abdominal surgery or from a recent abdominal trauma. The three cases presented here show a far more unusual picture of a band, one that is congenitally present, as there was an absence of such a history. This is significant because clinical suspicion of a band is often very low due to a lack of distinguishing clinical and diagnostic features, and when the past history is negative. PMID:27713389

    Introduction: Ileal perforation peritonitis is a common surgical emergency in the Indian subcontinent and in tropical countries. It is reported to constitute the fifth common cause of abdominal emergencies due to high incidence of enteric fever and tuberculosis in these management based on Acute Physiological and Chronic Health Evaluation II (APACHE II) score. Methods: The following study was conducted in the Department of General Surgery, Government Medical College, Patiala. A total of 57 patients were studied and divided in to Group I, II, and III. APACHE II score accessed and score between 10 and 19 were blindly randomized into three procedures primary closure, resection-anastomosis, and ileostomy. The outcome was compared. Results: Ileal perforations were most commonly observed in the third and fourth decade of life with male dominance. APACHE II score was accessed and out of total 57 patients, 6 patients had APACHE II score of 0–9, 48 patients had APACHE II score of 10–19, and 3 patients had APACHE II score of ≥20. In APACHE II score 10–19, 15 patients underwent primary closure, 16 patients underwent resection-anastomosis, and 17 patients underwent ileostomy. Discussion and Conclusion: Primary closure of perforation is advocated in patients with single, small perforation (<1 cm) with APACHE II score 10–19 irrespective of duration of perforation. Ileostomy is advocated in APACHE II score 10–19, where the terminal ileum is grossly inflamed with multiple perforations, large perforations (>1 cm), fecal peritonitis, matted bowel loops, intraoperative evidence of caseating lymph nodes, strictures, and an unhealthy gut due to edema.

    Trans - omental hernia is very rare, accounting to 1-4% of all internal hernias which is an unusual cause of small bowel obstruction. Here we present a case report of a small bowel obstruction in a female due to trans - omental hernia presenting with central abdominal pain, distension and bilious vomiting. She had no previous history of trauma, surgery. Plain X-ray abdomen erect showed multiple air fluid levels with dilated small bowel loops. Emergency laparotomy revealed a segment of congested small bowel loop (ileum) through a defect in greater omentum. On table the herniated bowel loop was reduced and the defect in greater omentum was closed primarily. There was no necessity for bowel resection as it regained normal colour after reduction. Postoperative period was uneventful with complete resolution of symptoms. This case is presented for its rarity and its importance in clinical differential diagnosis of acute abdomen due to small bowel obstruction.

    Gallstone ileus is a rare but important cause of small bowel obstruction in the geriatric population. A 65-year-old man with a twenty year history of cholecystolithiasis was admitted to our hospital with abdominal pain and vomiting. Physical exams showed abdominal defence and rebound tenderness. A plain abdominal X-ray suggested a small bowel obstruction and pneumobilia. CT scan revealed a 2.5-cm gallstone at the jejunum and air in the biliary tree. The patient underwent a emergency laparotomy based on a diagnosis of panperitonitis with a perforation associated with gallstone ileus. Operative findings revealed a jejunal perforation and a impacted stone on the anal side of perforation. Enterolithotomy and jejunal resection were performed with cholecystectomy and repairment of the cholecystoduodenal fistula.

    Background There is still confusion and controversy over the diagnosis and optimal surgical treatment of non traumatic terminal ileal perforation-a cause of obscure peritonitis. Methods This study was a prospective study aimed at evaluating the clinical profile, etiology and optimal surgical management of patients with nontraumatic terminal ileal perforation. Results There were 79 cases of nontraumatic terminal ileal perforation; the causes for perforation were enteric fever(62%), nonspecific inflammation(26%), obstruction(6%), tuberculosis(4%) and radiation enteritis (1%). Simple closure of the perforation (49%) and end to side ileotransverse anastomosis(42%) were the mainstay of the surgical management. Conclusion Terminal ileal perforation should be suspected in all cases of peritonitis especially in developing countries and surgical treatment should be optimized taking various accounts like etiology, delay in surgery and operative findings into consideration to reduce the incidence of deadly complications like fecal fistula.

    Abstract Background: Reactive perforating collagenosis (RPC) is a rare form of transepithelial elimination, in which altered collagen is extruded through the epidermis. There are 2 types of RPC, acquired RPC (ARPC) and inherited RPC, while the latter is extremely rare. Here we report on 1 case of ARPC. Methods: A 73-year-old female was presented with strongly itchy papules over her back and lower limbs for 3 months. She denied the history of oozing or vesiculation. A cutaneous examination showed diffusely distributed multiple well-defined keratotic papules, 4 to 10 mm in diameter, on the bilateral lower limbs and back as well as a few papules on her chest and forearm. Scratching scars were over the resolved lesions while Koebner phenomenon was negative. The patient had a history of type 2 diabetes for 15 years. Laboratory examinations showed elevated blood glucose level. Skin lesion biopsy showed a well-circumscribed area of necrosis filled with a keratotic plug. Parakeratotic cells and lymphocytic infiltration could be seen in the necrosed area. In dermis, sparse fiber bundles were seen perforating the epidermis. These degenerated fiber bundles were notarized as collagen fiber by elastic fiber stain, suggesting a diagnosis of RPC. Results: Then a diagnosis of ARPC was made according to the onset age and the history of diabetes mellitus. She was treated with topical application of corticosteroids twice a day and oral antihistamine once a day along with compound glycyrrhizin tablets 3 times a day. And the blood glucose was controlled in a satisfying range. Two months later, a significant improvement was seen in this patient. Conclusion: Since there is no efficient therapy to RPC, moreover, ARPC is considered to be associated with some systemic diseases, the management of the coexisting disease is quite crucial. The patient in this case received a substantial improvement due to the control of blood glucose and application of compound glycyrrhizin tablets. PMID

    Perforating is a very common well completion operation. Usually, it is considered to be as simple as making holes in casing. Actually, perforating is one of the most critical tasks for establishing a path from reservoir rock to borehole form which hydrocarbons can flow to surface. The objective of this article is to relate perforating technology with geological aspects and completion type to determine the best shooting equipment (gun type, charge and differential pressure) to perform the most efficient perforating job. Several subjects related to formation geology are taken into account for a shooting job, such as: compressive strength, reservoir pressure and thickness, lithology type, porosity and permeability, ratio between horizontal and vertical permeabilities, and fluid type. Gun geometry used in the oil industry incorporates several parameters, including shot density, hole entrance diameter, gun phase and jet penetration. API tests are done on perforating guns to define applicability and performance. A new geometrical parameter is defined as the relative angle of the jet, which is the angle between the jet tunnel and formation dip. GEOCAN is a methodology which relates geology to gun geometry and type to define the most efficient gun system for perforated completions. It uses the intelligent perforating technique with the SPAN (Schlumberger Perforating Analysis) program to confirm optimum gun choice.

    We present a rare case of large bowel obstruction secondary to colonic gallstones in a frail nonagenarian. Uniquely, the stone was impacted in the descending colon-sigmoid junction, in the absence of underlying bowel pathology distal to the stone. In light of worsening pain and distension after failed endoscopic treatment, the patient was treated with an emergency laparotomy. After an on-table dilemma, a proximal defunctioning loop colostomy was fashioned and the stone left in situ, with the eventual fate of the stone currently undecided. We also discuss alternative treatment options and explain the thought processes that lead to our decision. PMID:25002453

    We describe a case of esophageal perforation that resulted from a fishbone. A 71-year-old man had had a fishbone impacted in the lower esophagus for 2 days. At presentation, the bone was dislodged at endoscopy; one round opening in a deep ulceration was detected when the fishbone was removed. The perforation was closed by endoscopic hemoclipping, after the removal of the fishbone. A thoracic computed tomography revealed air around the esophagus, aorta and bronchus and the presence of a pleural effusion. These findings suggested mediastinal emphysema and mediastinitis due to the esophageal perforation after the removal of the fishbone. Esophagography revealed a focal esophageal defect and linear contrast leakage at the distal esophagus. The mediastinal emphysema and pleural effusion successfully resolved after the endoscopic hemoclip application and conservative management of the perforation.

    Strippings are problems that are frequent on thin and concave roots. Treatment and prognosis differ from that of a lateral root perforation because of the size, oval shape, and thin edges of the striping. We propose a two-step technique: an endodontic phase in which the root canal system is sealed with gutta-percha overflowing through the stripping perforation and a surgical second step that will allow elimination of this excess.

    A 36-year-old homeless Eritrean nulliparous woman was admitted to hospital, with abdominal pain, nausea and loss of appetite. She was found to be 17 weeks pregnant with dichorionic diamniotic twins. She was cachectic and had large palpable uterine fibroids. An extensive search for infection and malignancy did not yield any significant results. She was managed with enteral nutritional support and delivered healthy twins by emergency caesarean section at 36 weeks' gestation. She re-presented 19 days postpartum, with fever and abdominal pain. Imaging revealed multiple abdominal collections and large degenerating fibroids. At laparotomy, the fibroids were found to be adherent to, compressing and enveloping large sections of bowel. The patient required a right hemicolectomy, small bowel resection and total abdominal hysterectomy. Histology confirmed an infarcted leiomyoma and the patient made a good postoperative recovery.

    A gallstone ileus is an unusual form of bowel obstruction. Colonic gallstone ileus is rare, difficult to diagnose, and still has a high mortality rate. We present a case of biliary ileus caused by an impacted gallstone, causing necrosis and perforation of the rectosigmoid junction. A Hartmann's procedure was performed to treat the perforation and the obstruction. Cholecystectomy and closure of the cholecysto-colonic fistula were delayed until restoration of the intestinal continuity.

    Background: Perforator flaps are well established, and their usefulness as freestyle island flaps is recognized. The whereabouts of vascular perforators and classification of perforator flaps in the face are a debated subject, despite several anatomical studies showing similar consistency. In our experience using freestyle facial perforator flaps, we have located areas where perforators are consistently found. This study is focused on a particular perforator lateral to the angle of the mouth; the modiolus and the versatile modiolus perforator flap. Methods: A cohort case series of 14 modiolus perforator flap reconstructions in 14 patients and a color Doppler ultrasonography localization of the modiolus perforator in 10 volunteers. Results: All 14 flaps were successfully used to reconstruct the defects involved, and the location of the perforator was at the level of the modiolus as predicted. The color Doppler ultrasonography study detected a sizeable perforator at the level of the modiolus lateral to the angle of the mouth within a radius of 1 cm. This confirms the anatomical findings of previous authors and indicates that the modiolus perforator is a consistent anatomical finding, and flaps based on it can be recommended for several indications from the reconstruction of defects in the perioral area, cheek and nose. Conclusions: The modiolus is a well-described anatomical area containing a sizeable perforator that is consistently present and readily visualized using color Doppler ultrasonography. We have used the modiolus perforator flap successfully for several indications, and it is our first choice for perioral reconstruction. PMID:27257591

    Jejunal pseudo-diverticulosis is a rare acquired herniation of the mucosa and submucosa through weakened areas of the muscularis mucosa of the mesenteric aspect of the bowel. They are asymptomatic in the majority of cases; however, they can present with a wide spectrum of non-specific symptoms such as chronic abdominal discomfort, postprandial flatulence, diarrhoea, malabsorption and steattorhoea. In up to 15% of cases, more serious acute complications may arise such as the development of intestinal obstruction, haemorrhage or as in our case, localized peritonitis secondary to perforation. Perforation carries an overall mortality rate of up to 40% and exploratory laparotomy followed by copious lavage with segmental resection and primary anastomosis remains the mainstay of managing such sequalae of jejunal pseudo-diverticulosis. Our case report highlights the importance of maintaining a high clinical suspicion of a perforated jejunal diverticulum in an elderly patient presenting with an acute abdomen. PMID:27765806

    Enteric protozoan infections are a well-documented cause of diarrhea in immunocompromised patients. Special stains on stool specimens are routinely performed in such patients to diagnose these protozoa namely cryptosporidium, microsporidium, and isospora. Duodenal and jejunal biopsies can also be performed to obtain a tissue diagnosis. We report a case of microsporidium enteritis diagnosed on histopathological examination of small bowel resection specimen in a case of perforation peritonitis. The patient was a known HIV-positive on antiretroviral treatment for 2 years and on antitubercular treatment for 3 months. This case report highlights the importance of carefully screening the resection specimens for protozoal infections in immunocompromised individuals. The association of perforation peritonitis and microsporidium is rare. Hence, the possibility that untreated microsporidium infection can lead to perforation cannot be ruled out.

    The incidence of the diverticulum of the small bowel varies from 0.2-1.3% in autopsy studies to 2.3% when assessed on enteroclysis. It occurs mostly in patients in the 6th decade of their life. Of all the small bowel diverticuli, jejunal diverticulum is the most common type. This rare entity is usually asymptomatic. However, they may cause chronic non-specific symptoms for a long period of time like dyspepsia, chronic postprandial pain, nausea, vomiting, borborgymi, alternating diarrhoea and constipation, weight loss, anaemia, steatorrhea or rarely lead to complications like haemorrhage, obstruction, perforation. Obstruction can be due to enterolith, adhesions, intussusception, and volvulus. The condition is difficult to diagnose because patients are generally presented with symptoms that mimic other diseases. It is important for clinicians to have awareness of this entity. Here, we present a case of multiple jejunal diverticuli with a history of repeated attacks of diverticulitis over past 20 years, which were misdiagnosed and now presented with intestinal obstruction due to volvulus of the involved segment along with mesentery around its axis. Resection of the diverticuli segment of jejunum was done with end-to-end jejuno-jejunal anastomosis. The patient is asymptomatic since 10 months of follow-up. PMID:27853337

    Fish bones are the most common foreign objects leading to bowel perforation. Most cases are confined to the extraluminal space without penetration of an adjacent organ. However, abscess formation due to the perforation of the rectosigmoid colon by a fish bone can lead to the penetration of the urinary bladder and may subsequently cause the fish bone to migrate into the urinary bladder. In the presented case, a 42-year-old female was admitted for lower abdominal pain. The computed tomography (CT) demonstrated a 5 cm pelvic abscess containing a thin and curvilinear foreign body. After conservative management, the patient was discharged. After 1 mo, the subject developed a mechanical ileus. Surgery had to be delayed due to her hyperthyroidism. Migration of the foreign body to the urinary bladder was shown on additional CT. A Yellowish fish bone 3.5 cm in size was removed through intra-operative cystoscopy. The patient was discharged 8 d after the operation without any unexpected event.

    Pyometra is collection of purulent material which occurs when there is interference with its normal drainage. It is an uncommon condition with incidence of 0.1 to 0.5% of all gynecological patients. Spontaneous rupture of uterus is an extremely rare complication of pyometra. A 65-year-old lady presented with pain abdomen and purulent vaginal discharge. Preoperative diagnosis of pyometra was made by magnetic resonance imaging (MRI). Laparotomy followed by peritoneal lavage and repair of perforation was performed. Although spontaneously perforated pyometra is rare, the condition must be borne in mind with regard to elderly women with acute abdominal pain. Preoperative diagnosis of perforated pyometra is absolutely essential. Computed tomography (CT) and MRI are diagnostic tools. In selected cases conservative approach at surgery can be opted.

  3. Perforated diode neutron sensors

    NASA Astrophysics Data System (ADS)

    McNeil, Walter J.

    A novel design of neutron sensor was investigated and developed. The perforated, or micro-structured, diode neutron sensor is a concept that has the potential to enhance neutron sensitivity of a common solid-state sensor configuration. The common thin-film coated diode neutron sensor is the only semiconductor-based neutron sensor that has proven feasible for commercial use. However, the thin-film coating restricts neutron counting efficiency and severely limits the usefulness of the sensor. This research has shown that the perforated design, when properly implemented, can increase the neutron counting efficiency by greater than a factor of 4. Methods developed in this work enable detectors to be fabricated to meet needs such as miniaturization, portability, ruggedness, and adaptability. The new detectors may be used for unique applications such as neutron imaging or the search for special nuclear materials. The research and developments described in the work include the successful fabrication of variant perforated diode neutron detector designs, general explanations of fundamental radiation detector design (with added focus on neutron detection and compactness), as well as descriptive theory and sensor design modeling useful in predicting performance of these unique solid-state radiation sensors. Several aspects in design, fabrication, and operational performance have been considered and tested including neutron counting efficiency, gamma-ray response, perforation shapes and depths, and silicon processing variations. Finally, the successfully proven technology was applied to a 1-dimensional neutron sensor array system.

    The advent of mesh devices allowed for tension-free inguinal hernia repairs and a subsequent reduction in the rate of recurrences. In 1993, Rutkow and Robbins introduced the plug-and-patch repair method whereby the hernia defect is filled with a mesh plug. This new procedure led to new technique-specific complications. Here, we report the case of a man who presented with obstructive symptoms and pain at the site of his inguinal hernia repair performed with the Prolene Hernia System((R)) 18 months prior. At laparotomy, he was found to have a small bowel obstruction and perforation due to mesh contact with the small bowel and colon. The literature is reviewed for cases of bowel complications due to mesh plugs. Based on reported complications, three recommendations can be made to avoid or reduce the risk of this complication. First, the pre-peritoneal dissection should be performed carefully with particular attention to identify and repair any tears of the peritoneum. Secondly, the mesh plug should not be placed too deep within the defect. Finally, the plug should be secured to reduce the possibility of mesh migration.

    Background To determine the indications, nature, and rate of early complications of temporary loop ileostomy created in emergency for benign diseases, their management, and to find out the associated risk factors. Methods A total of 630 patients undergoing temporary loop ileostomy for benign diseases were studied prospectively over a period of 6 years. Stoma-related early complications occurring within 6-8 weeks were analyzed. Only emergency cases were included in this study. Descriptive statistics were used to summarize the data and statistical significance was evaluated by applying the Pearson’s chi-square test. Results Typhoid perforation (n=402) was the most commonpathology, followed by tuberculosis (n=106); trauma (n=81); and intestinal obstruction with gangrenous bowel (n=41). 299 patients had no stoma-related complications. Skin excoriation was the most commonstoma-related complication. Age more than 50 years; shock at presentation; delay in presentation; delay in surgery; presence of comorbidities; and surgery done out of working hours, were associated with increased complications. Conclusion Temporary loop ileostomy for perforation peritonitis due to benign systemic diseases like typhoid fever and tuberculosis confers a very high morbidity. PMID:25609137

    Background Esophageal trauma is considered one of the most severe lesions of the digestive tract. There is still much controversy in choosing the best treatment for cases of esophageal perforation since that decision involves many variables. The readiness of medical care, the patient's clinical status, the local conditions of the perforated segment, and the severity of the associated injuries must be considered for the most adequate therapeutic choice. Aim To demonstrate and to analyze the results of urgent esophagectomy in a series of patients with esophageal perforation. Methods A retrospective study of 31 patients with confirmed esophageal perforation. Most injuries were due to endoscopic dilatation of benign esophageal disorders, which had evolved with stenosis. The diagnosis of perforation was based on clinical parameters, laboratory tests, and endoscopic images. ‪The main surgical technique used was transmediastinal esophagectomy followed by reconstruction of the digestive tract in a second surgical procedure. Patients were evaluated for the development of systemic and local complications, especially for the dehiscence or stricture of the anastomosis of the cervical esophagus with either the stomach or the transposed colon. Results Early postoperative evaluation showed a survival rate of 77.1% in relation to the proposed surgery, and 45% of these patients presented no further complications. The other patients had one or more complications, being pulmonary infection and anastomotic fistula the most frequent. The seven patients (22.9%) who underwent esophageal resection 48 hours after the diagnosis died of sepsis. At medium and long-term assessments, most patients reported a good quality of life and full satisfaction regarding the surgery outcomes. Conclusions Despite the morbidity, emergency esophagectomy has its validity, especially in well indicated cases of esophageal perforation subsequent to endoscopic dilation for benign strictures.

    Ingested foreign bodies tend to pass through the gastrointestinal tract without incidence, and vast majority of cases do not need intervention. Rarely, these foreign bodies drop into the appendix and not likely to re-enter the normal digestive tract. We describe a case of a 72-year-old male patient who presented with right iliac fossa pain of 3-day duration. Clinical examination suggested classic acute appendicitis. Blood test results revealed leukocytosis. Computed tomography of the abdomen and pelvis showed evidence of acute appendicitis and a linear hyperdensity (foreign body) perforating the appendix. The patient was managed successfully with prompt laparoscopic appendectomy and removal of the foreign body which was confirmed to be a fish bone measuring about 10mm. While imaging diagnosis of fishbone in the appendix has been published, reports are few. To the best of the author's knowledge, fishbone induced perforated appendicitis has been described only in 2 cases (including this case) in the literature.

  13. Small Bowel Transplant

    PubMed Central

    2003-01-01

    EXECUTIVE SUMMARY Objective The Medical Advisory Secretariat undertook a review of the evidence on the effectiveness and cost-effectiveness of small bowel transplant in the treatment of intestinal failure. Small Bowel Transplantation Intestinal failure is the loss of absorptive capacity of the small intestine that results in an inability to meet the nutrient and fluid requirements of the body via the enteral route. Patients with intestinal failure usually receive nutrients intravenously, a procedure known as parenteral nutrition. However, long-term parenteral nutrition is associated with complications including liver failure and loss of venous access due to recurrent infections. Small bowel transplant is the transplantation of a cadaveric intestinal allograft for the purpose of restoring intestinal function in patients with irreversible intestinal failure. The transplant may involve the small intestine alone (isolated small bowel ISB), the small intestine and the liver (SB-L) when there is irreversible liver failure, or multiple organs including the small bowel (multivisceral MV or cluster). Although living related donor transplant is being investigated at a limited number of centres, cadaveric donors have been used in most small bowel transplants. The actual transplant procedure takes approximately 12-18 hours. After intestinal transplant, the patient is generally placed on prophylactic antibiotic medication and immunosuppressive regimen that, in the majority of cases, would include tacrolimus, corticosteroids and an induction agent. Close monitoring for infection and rejection are essential for early treatment. Medical Advisory Secretariat Review The Medical Advisory Secretariat undertook a review of 35 reports from 9 case series and 1 international registry. Sample size of the individual studies ranged from 9 to 155. As of May 2001, 651 patients had received small bowel transplant procedures worldwide.

    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.

  15. Radiologic diagnosis of gastrointestinal perforation.

    2003-11-01

    Perforations of the gastrointestinal tract have many causes. Holes in the wall of gastrointestinal organs can be created by blunt or penetrating trauma, iatrogenic injury, inflammatory conditions that penetrate the serosa or adventitia, extrinsic neoplasms that invade the gastrointestinal tract, or primary neoplasms that penetrate outside the wall of gastrointestinal organs. This article provides a radiologic approach for investigating the wide variety of gastrointestinal perforations. General principles about contrast agents and studies are reviewed, and then perforations in specific gastrointestinal organs are discussed.

    The conventional pedicled sternocleidomastoid (SCM) flap has a poor arc of rotation, limited volume and precarious vascularity. This report describes a new technique for raising a SCM flap based on the perforating vessels of the superior thyroid vascular pedicle. The upper and lower attachments of the sternocleidomastoid muscle are divided. Four medically and/or surgically compromised patients have successfully undergone reconstruction of hemiglossectomy (1), partial glossectomy (1) and rim of mandible (2) defects for malignancy. The arc of rotation of the SCM flap is greatly increased and the potential applications for the flap expanded.

    Ingested foreign bodies tend to pass through the gastrointestinal tract without incidence, and vast majority of cases do not need intervention. Rarely, these foreign bodies drop into the appendix and not likely to re-enter the normal digestive tract. We describe a case of a 72-year-old male patient who presented with right iliac fossa pain of 3-day duration. Clinical examination suggested classic acute appendicitis. Blood test results revealed leukocytosis. Computed tomography of the abdomen and pelvis showed evidence of acute appendicitis and a linear hyperdensity (foreign body) perforating the appendix. The patient was managed successfully with prompt laparoscopic appendectomy and removal of the foreign body which was confirmed to be a fish bone measuring about 10mm. While imaging diagnosis of fishbone in the appendix has been published, reports are few. To the best of the author’s knowledge, fishbone induced perforated appendicitis has been described only in 2 cases (including this case) in the literature. PMID:27761185

    Gallstone ileus is a well-established phenomenon in which a large gallstone leads to mechanical small bowel obstruction. This case, however, reports the novel finding of a patient presenting with suprapubic pain and guarding caused by paralytic ileus of the small bowel and a duodenal perforation secondary to a necrotic gallbladder. It highlights the importance of distinguishing between gallstone ileus and paralytic ileus and how the management of the two conditions differs. Furthermore, this article discusses how paralytic ileus caused by intra-abdominal inflammatory conditions such as cholecystitis can mask the typical clinical findings making the diagnosis difficult.

    Spontaneous bladder perforation secondary to tuberculosis (TB) is very rare. Only three cases have been reported so far in the literature. Due to its rarity, the diagnosis of spontaneous bladder perforation is often missed. Confirmation of TB via culture takes a long time and starting empirical treatment for TB is necessary. We relate our experience with a young woman who presented with clinical features of a perforated appendix and was only diagnosed with bladder perforation during laparotomy. She also had distal right ureteral stricture and left infundibular stenosis. The provisional diagnosis of TB was attained via typical histopathological features and a positive Mantoux test. She was started empirically on anti-TB treatment and recovered without any complications. Urine culture after 6 weeks confirmed the diagnosis of TB.

    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.

    Rett Syndrome is associated with decreased peristaltic esophageal waves and gastric dysmotility, resulting in swallowing difficulties and gastric dilation. Rarely, gastric necrosis and perforation occur. Our case represents the third reported case of gastric necrosis and perforation associated with Rett Syndrome. A 31-year-old female after 11 hours of intermittent emesis and constant, sharp abdominal pain presented with evidence of multiorgan system failure including hypovolemic shock, metabolic acidosis, coagulopathy, and hepatorenal failure. A chest radiograph revealed intra-abdominal free air necessitating emergent laparotomy. During exploration, a severely dilated, thin-walled stomach with an area of necrosis and gross perforation was noted. Wedge resection of the necrotic tissue and primary closure were performed. Despite aggressive perioperative resuscitation and ventilation support, the patient died 3 hours postoperatively secondary to refractory shock and hypoxemia. Severe gastric dilation can occur with Rett Syndrome and may cause gastric necrosis and perforation. Prolonged elevated gastric pressures can decrease perfusion and may contribute to perforation. Timely decompression via percutaneous endoscopic or surgical gastrostomy could decrease the risk of perforation particularly when significant gastric distention is present. Consideration of gastric necrosis and perforation in patients with Rett Syndrome may lead to earlier intervention and decreased mortality.

    Phytobezoar is an unusual cause of small bowel obstruction. It accounts for about 0.4%-4% of all mechanical bowel obstruction. However, the symptoms are not very different from those caused by usual aetiologies of small bowel obstruction. The commonest site of obstruction is terminal ileum. Treatment of small bowel obstruction due to Phytobezoar is surgery. Prevention includes avoidance of high fibre diet, prokinetics particularly in patients who have undergone gastric surgery. A 57-year-old male presented with symptoms and signs of small bowel obstruction. On exploratory laparotomy Phytobezoar in the ileum was found to be the cause of obstruction. Diagnosis was confirmed by histopathology.

    Perforator flaps have become very popular in reconstructive surgery. The thoracodorsal and lateral thoracic artery perforator flaps are highly studied, and successful clinical series have been reported, whereas the literature concerning the lateral intercostal and serratus anterior artery perforator flaps is quite poor and their vascular anatomy needs yet to be clarified. We describe a case of free serratus anterior artery perforator flap for the reconstruction of a dorsal defect of the foot, followed by an anatomic and radiological study. A 17-year-old boy reported a fracture of the first and second metatarsal bone of the left foot, with a dorsal skin defect, due to a motorcycle accident. After the osteosynthesis treatment, a perforator was identified through a handheld Doppler in the lateral chest area and a cutaneous paddle was designed. Retrograde dissection revealed the perforator's direct link to the serratus anterior pedicle. In our knowledge, an elucidated method to preoperatively visualize the perforating vessel of the serratus anterior artery has not yet been described. Thus, an anatomic study on 8 hemithorax and a radiological study on 33 computed tomographic angiographies of the chest were carried out to clarify the vascular anatomy of the serratus anterior artery perforators and to verify the possibility of their preoperative visualization. The authors believe that the serratus anterior artery perforator could be preoperatively investigated, thus making this flap a valuable option when harvesting a perforator flap in the lateral chest area.

    Introduction. Ileal perforation peritonitis is a frequently encountered surgical emergency in the developing countries. The choice of a procedure for source control depends on the patient condition as well as the surgeon preference. Material and Methods. This was a prospective observational study including 41 patients presenting with perforation peritonitis due to ileal perforation and managed with ileostomy. Demographic profile and operative findings in terms of number of perforations, site, and size of perforation along with histopathological findings of all the cases were recorded. Results. The majority of patients were male. Pain abdomen and fever were the most common presenting complaints. Body mass index of the patients was in the range of 15.4–25.3 while comorbidities were present in 43% cases. Mean duration of preoperative resuscitation was 14.73 + 13.77 hours. Operative findings showed that 78% patients had a single perforation; most perforations were 0.6–1 cm in size and within 15 cm proximal to ileocecal junction. Mesenteric lymphadenopathy was seen in 29.2% patients. On histopathological examination, nonspecific perforations followed by typhoid and tubercular perforations respectively were the most common. Conclusion. Patients with ileal perforations are routinely seen in surgical emergencies and their demography, clinical profile, and intraoperative findings may guide the choice of procedure to be performed.

    Objective: Inflammatory bowel diseases (IBDs) are idiopathic, chronic, and inflammatory intestinal disorders. The two main types, ulcerative colitis (UC) and Crohn’s disease (CD), sometimes mimic each other and are not readily distinguishable. The purpose of this study was to present a series of hospitalized cases, which could not initially be classified as a subtype of IBD, and to try to note roles of the terms indeterminate colitis (IC) and inflammatory bowel disease unclassified (IBDU) when such a dilemma arises. Methods: Medical records of 477 patients hospitalized due to IBD, during the period of January 2002 to April 2009, were retrospectively studied in the present paper. All available previous biopsies from endoscopies of these patients were reanalyzed. Results: Twenty-seven of 477 IBD patients (5.7%) had been initially diagnosed as having IBDU. Of them, 23 received colonoscopy and histological examinations in our hospital. A total of 90% (9/10) and 66.7% (4/6) of patients, respectively, had a positive finding via wireless capsule endoscopy (CE) and double-balloon enteroscopy (DBE). The barium-swallow or small bowel follow-through (SBFT) was performed on 11 patients. Positive changes were observed under computer tomographic (CT) scanning in 89.5% (17/19) of patients. Reasonable treatment strategies were employed for all patients. Conclusions: Our data indicate that IBDU accounts for 5.7% of initial diagnoses of IBD. The definition of IBDU is valuable in clinical practice. For those who had no clear clinical, endoscopic, histological, or other features affording a diagnosis of either UC or CD, IBDU could be used parenthetically. PMID:21462383

    Esophageal perforation occurring during or after endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) is a rare, but serious complication. However, reports of its characteristics, including endoscopic imaging and management, have not been fully detailed. To analyze and report the clinical presentation and management of esophageal perforations occurred during or after EMR/ESD. Four hundred seventy-two esophageal neoplasms in 368 patients were treated (171 EMR; ESD 306) at Northern Yokohama Hospital from 2003 to 2012. Esophageal perforation occurred in a total of seven (1.9%) patients, all of whom were male and had undergone ESD. The etiology of perforation was: three (42.9%) intraoperative; three (42.9%) balloon dilatation for stricture prevention; one (14.2%) due to food bolus impaction. All cases were managed non-operatively based on the comprehensive assessment of clinical severity, extent of the injury, and the time interval from perforation to treatment onset. Conservative management included (i) bed rest and continuous monitoring to determine the need for operative intervention; (ii) fasting and intravenous fluid infusion/ tube feeding; and (iii) intravenous antibiotics. All defects closed spontaneously, save one case where closure was achieved by endoscopic clipping. Surgery was not required. Conservative management for esophageal perforation during advanced endoscopic resection is may be possible when there is no delay in diagnosis or treatment. Decision-making should be governed purely by multidisciplinary discussion.

    A bezoar is a concretion of foreign or indigestible matter in the alimentary canal and is usual cause of gastric obstruction. Bezoars can become fragmented and migrate downward leading to intestinal obstruction. Diagnosis of phytobezoar has become challenging in clinical practice due to lack of patient history and inability of patient to correlate preceding events with the episode of bowel obstruction. Bezoar associated small bowel obstruction rarely occurs and is usually found in patients with history of gastrointestinal surgery. Very few cases are reported of small bowel obstruction due to bezoar in healthy population without prior illness or surgery. We present a case of small bowel obstruction due to mushroom bezoar in a 62-year patient with no past history of medical illness or gastric surgery. Enterotomy was performed and a whole piece of undigested mushroom measuring 5 x 3 cm was successfully removed.

    AIM: To assess the incidence and risk factors associated with colonic perforation due to colonoscopy. METHODS: This was a retrospective cross-sectional study. Patients were retrospectively eligible for inclusion if they were 18 years and older and had an inpatient or outpatient colonoscopy procedure code in any facility within the Geisinger Health System during the period from January 1, 2002 to August 25, 2010. Data are presented as median and inter-quartile range, for continuous variables, and as frequency and percentage for categorical variables. Baseline comparisons across those with and without a perforation were made using the two-sample t-test and Pearson’s χ2 test, as appropriate. RESULTS: A total of 50 perforations were diagnosed out of 80118 colonoscopies, which corresponded to an incidence of 0.06% (95%CI: 0.05-0.08) or a rate of 6.2 per 10000 colonoscopies. All possible risk factors associated with colonic perforation with a P-value < 0.1 were checked for inclusion in a multivariable log-binomial regression model predicting 7-d colonic perforation. The final model resulted in the following risk factors which were significantly associated with risk of colonic perforation: age, gender, body mass index, albumin level, intensive care unit (ICU) patients, inpatient setting, and abdominal pain and Crohn’s disease as indications for colonoscopy. CONCLUSION: The cumulative 7 d incidence of colonic perforation in this cohort was 0.06%. Advanced age and female gender were significantly more likely to have perforation. Increasing albumin and BMI resulted in decreased risk of colonic perforation. Having a colonoscopy indication of abdominal pain or Crohn’s disease resulted in a higher risk of colonic perforation. Colonoscopies performed in inpatients and particularly the ICU setting had substantially greater odds of perforation. Biopsy and polypectomy did not increase the risk of perforation and only three perforations occurred with screening colonoscopy

    Esophageal perforation is a difficult problem in thoracic surgery. Esophageal perforations can be spontaneous, iatrogenic, or malignant. We report two cases of esophageal perforations caused by thoracic osteophytes and different management strategies leading to successful outcomes. An 80-year-old male presented with chest pain and dysphagia following a fall. On endoscopy, an esophageal perforation and foreign body was noted which was confirmed as a thoracic osteophyte on computed tomography scan. He was managed conservatively as he declined surgery. A 63-year-old male was admitted with dysphagia following a food bolus obstruction. Following esophagoscopy and dilatation, there was clinical and radiological evidence of perforation. During surgery, a thoracic osteophyte was identified as the cause of perforation. The perforation was closed in layers and the osteophyte was trimmed. Both patients recovered well. Thoracic osteophytes are a rare cause of esophageal perforations and a high index of suspicion is required in patients with osteoarthritis who present with esophageal perforations.

    This paper discusses the effects of various perforation and reservoir parameters on the productivity (or injectivity) of perforated completions. Because of the complex, 3D flow into a spiral system of perforations, productivity analysis of perforated completion is not easily amenable to analytical treatment. This paper presents a semianalytical solution for the estimation of skin in perforated completions. Results are presented for two separate cases: the 2D-plane-flow problem, which is essentially valid at small dimensionless perforation spacings (large perforation penetrations or high perforation shot densities) and the general 3D problem, where the vertical convergent flow into perforations is significant. In these analyses, the wellbore and vertical-flow effects are quantified in terms of pseudoskins obtained by accurate finite-element simulations. The effects of perforation damage and formation anisotropy are also included. The results provide a better understanding of the relative role of various perforation parameters in affecting well productivity. Because they are based on theoretical considerations, the correlations allow reliable estimates of the skin in perforated completions. New relations are provided for estimating productivity of perforated completions with formation permeability damage. Results indicate the importance of angular phasing, in addition to perforation penetration, in overcoming the effects of formation damage on well productivity.

    Small bowel perforation is a unique, serious complication during endometrial biopsy. The authors report a case of a double uterine-ileal perforation totally managed by primary laparoscopic repair. A 63-year-old female was admitted with acute abdomen 2 days after an endometrial curettage. Abdominal X-ray shows signs of pneumoperitoneum. Emergency diagnostic laparoscopy was performed and a uterine-ileal perforation was identified. Repair was accomplished by a totally laparoscopic intracorporeally suturing of the 2 breaches. Postoperative course showed only a delayed ileus and the patient was discharged after 5 days with no complications. When acute abdomen arises following uterine biopsy, a potential iatrogenic intestinal laceration always has to be ruled out. Laparoscopic approach is a quick and safe technique in these cases. Totally laparoscopic primary closure of the iatrogenic ileal laceration may be accomplished with low morbidity. PMID:25692425

    Introduction. Gallstone ileus (GSI) of the colon is an extremely rare entity with potentially serious complications including perforation. Case Presentation. An 88-year-old man presented to the emergency department with abdominal pain and distension. Clinical exam revealed signs of peritonism. Computed tomography (CT) revealed GSI of the transverse colon with a closed-loop large bowel obstruction (LBO) and caecal perforation. The patient underwent emergency laparotomy. A right hemicolectomy was performed, the gallstone was removed, and a primary bowel anastomosis was undertaken. A Foley catheter was sutured into the residual gallbladder bed to create a controlled biliary fistula. The patient recovered well postoperatively with no complications. He was discharged home with the Foley catheter in situ. Discussion. Gallstone ileus is a difficult diagnosis both clinically and radiologically with only 50% of cases being diagnosed preoperatively. Most commonly it is associated with impaction at the ileocaecal valve and small bowel obstruction. Gallstone ileus should also be considered as a rare but potential cause of LBO. This is the first reported case of caecal perforation secondary to gallstone ileus of the transverse colon. Successful operative management consisted of a one-stage procedure with right hemicolectomy and formation of a controlled biliary fistula.

This sign can be more frequently mistaken for pneumoperitoneum which is usually an indication of bowel perforation and can lead to needless surgical intervention. There are several case report reported in literature that describe the association between colonic volvulus and Chilaiditi syndrome that underline the frequent association between these anatomical condition instead no previous report described the association between Chilaiditi syndrome and large bowel obstruction secondary to a malignant sigmoid stenosis in a man presenting with symptoms and signs of upper respiratory distress combined with subacute bowel obstruction.

    2015-01-01

    Posttraumatic diaphragmatic hernia is a rare cause of large bowel obstruction, and can present weeks or years after the initial trauma. Herein, we report the case of a 28-year-old man who presented with signs and symptoms of bowel obstruction nine months after he had a stab wound to his left chest. Chest radiography showed multiple air-fluid levels in the right upper quadrant, an air-fluid level in the left thoracic cavity and significant free air under the diaphragm. Exploratory laparotomy revealed a contaminated abdomen with perforations in the caecum and proximal transverse colon, and a 4 cm × 4 cm defect in the left posterolateral (septal) aspect of the diaphragm, which was closed with a nonabsorbable suture. Posttraumatic diaphragmatic hernias should be part of the differential diagnosis for patients with bowel obstruction, especially if there is a history of trauma. Radiography is useful in facilitating a quick diagnosis. PMID:25917476

    2016-09-01

    In patients with prior coronary artery bypass graft (CABG) surgery, distal coronary perforations are commonly considered to be at low risk for causing cardiac tamponade due to a potential protective role of pericardial adhesions, which obliterate the pericardial space. Loculated effusions can however form in such patients, compressing various cardiac structures and causing hemodynamic compromise. We present two cases of distal coronary perforation in prior CABG patients undergoing chronic total occlusion percutaneous coronary intervention. In the first case a distal coronary perforation was initially observed, resulting in a loculated pericardial effusion that caused ST-segment elevation and death, despite successful sealing of the perforation. In the second case a similar perforation was immediately sealed with a covered stent, followed by uneventful patient recovery. A literature review of coronary perforation leading to hemodynamic compromise in patients with prior CABG surgery revealed high mortality (22%), suggesting that prompt sealing of the perforation is critical in these patients.

    Introduction: Percutaneous nephrolithotomy (PCNL) is the treatment of choice for large, extracorporeal lithotripsy failure stones and those in the inferior calyx. Despite the development of new techniques and the increasing experience in recent decades, complications may still occur. Colonic perforation is one of the most dangerous and rare complications of PCNL, which may lead to peritonitis and sepsis. We present our 18-year experience on the diagnosis and management of colonic perforation during PCNL Methods: We retrospectively reviewed the data of 5260 PCNL procedures performed between May1995 and August 2013. Preoperative and operative factors, such as age, sex, history of previous ipsilateral stone intervention, stone side, stone location, site of skin puncture and punctured calyx, were reviewed in patients with colonic injury. Results: Colonic perforation was found in 11 patients (5 males and 6 females) and the mean age was 40.4 ± 22.2 years (range: 4 to 71). All injuries were retroperitoneal. The left side was affected in 5 patients and the right side was injured in 6 cases. Conservative management was the treatment planned for all patients. It included withdrawal of the nephrostomy tube outside the kidney to the colon as a percutaneous colostomy, insertion of a double-J ureteral stent, intravenous broad-spectrum antibiotics, bowel rest and total parenteral nutrition. Under this conservative management, complete healing of the colon was achieved in all patients. Conclusion: Early diagnosis and conservative management of colonic perforation can minimize patient morbidity and mortality and result in excellent healing of the fistulous tract without any serious complications.

    Primary malignant tumors of the small bowel are uncommon and are often diagnosed at an advanced stage. A 10 year survey (1967 to 1977) of the clinical records at one hospital revealed 39 cases of primary malignant tumors of the small bowel. The most common symptoms were abdominal pain (89.7 percent) and weight loss (77 percent). Six patients presented with complications of enterovesical fistula, bleeding and perforation. Preoperative diagnosis was suspected in 27 cases (69.2 percent). Adenocarcinoma was the most common tumor, followed by carcinoid tumor, lymphoma, leiomyosarcoma and melanoma. The treatment of choice was surgical resection whenever possible. Curative resection was attempted in 25 cases. Adjuvant radiotherapy and chemotherapy was used in four patients with lymphoma. Twenty-seven patients (69.2 percent) are alive from 1 to 6 years after diagnosis and treatment. The 5 year survival rate is 35 percent. Earlier diagnosis is essential if the prognosis for patients with small bowel malignancy is to be improved.

  4. Evaluation of flow characteristics of perforations including nonlinear effects using finite-element method

    This study presents results of finite element modelling of steady-state flow in perforated natural completions. Use of a carefully chosen mesh based on grid sensitivity analysis permits evaluation of flow with more precision than achieved by previous investigators. Also, for the first time, evaluation of flow characterstics of perforated completion is made taking into account the non-Darcy effect due to converging flow around the perforation. The results indicate: (1) confirmation of Locke's findings qualitatively but 5-10% overprediction by the nomograph (2) importance of angular phasing between adjacent perforations, (3) untenability of generally accepted severe permeability impairment in the compacted zone, and (4) significant reduction in productivity due to non-Darcy effect around the perforation for high-rate wells.

    Patients with advanced or metastatic cancer have compromised nutritional, metabolic, and immune conditions. Nevertheless, little is known about gastroduodenal perforation in cancer patients. Described in the present report is the case of a 41-year old woman with stage IV recurrent laryngeal cancer, who used homeopathic anticancer therapy and who had triple peptic ulcer perforation (PUP) that required surgical repair. Triple gastric PUP is a rare complication. Self-administration of homeopathic anticancer medication should be strongly discouraged when evidence-based data regarding efficacy and toxicity is lacking.

    1995-12-31

    The flow velocity of the one dimensional, single phase flow within an individual perforation is determined using an ultrasonic Doppler technique. This new technique takes advantage of the fact that flow in an individual perforation is often single phase even when flow in the wellbore is not. Existing techniques for determining multi-phase flow rates in a well bore have many limitations, due in large part to the complexity of the many possible flow regimes. An innovative approach which partially circumvents this problem has been investigated experimentally. Work has been done using an experimental set-up simulating a well bore, with water as the fluid. Since the diameter of perforations for a known gun type and casing can be reasonably estimated, flow rate within an individual perforation can be determined from velocity. Comparison of the calculated flow rates with actual flow rates are encouraging, both in turbulent and laminar flows. It is envisioned that a televiewer-like tool could be developed to scan the entire perforated interval while logging, providing a complete description of flow entries and exits.

    Gastric perforation secondary to metastasis from breast cancer occurs infrequently. We present the case of a 72-year-old postmenopausal female patient with a known history of lobular carcinoma of the breast who presented to a district general hospital with a clinical diagnosis of an acute abdomen. Further contrast-enhanced CT scan demonstrated free gas and fluid in the abdomen. She underwent emergency exploratory laparotomy and onlay Graham's omentopexy patch due to 1×1 cm prepyloric gastric perforation. Final histopathology proved the presence of metastatic malignant cells in the breast origin. We discuss the issues involved in postoperative investigation and management.

    Spontaneous urinary bladder perforation is a rare event, which requires immediate medical attention due to its extremely high morbidity and mortality. We report a case of a 36-year-old man who presented with acute-onset abdominal pain without any inciting events. His glucose level at the time of presentation was 1107 mg/dL. On initial abdominal imaging, it was believed that he had a large pelvic mass likely originating from the bladder. On further workup at our hospital, it was discovered that he had an intraperitoneal perforation after which he underwent an exploratory laparotomy and a cystorrhaphy. PMID:26955559

  10. Psychological Interventions for Irritable Bowel Syndrome and Inflammatory Bowel Diseases

    2017-01-01

    Psychological interventions have been designed and implemented effectively in a wide range of medical conditions, including Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Diseases (IBD). The psychological treatments for IBS and IBD with the strongest evidence base include: cognitive behavioral therapy, hypnosis, and mindfulness-based therapies. The evidence for each of these therapies is reviewed here for both IBS and IBD. In general, there is a stronger and larger evidence base to support the use of psychological interventions in IBS compared with IBD. This is likely due to the high level of psychiatric comorbidity associated with IBS and the involvement of the stress-response in symptom presentation of IBS. Further research in psychosocial interventions for IBD is necessary. Finally, the importance of conceptualizing both IBS and IBD in a biopsychosocial model is discussed and several resources for accessing Clinical Health Psychology materials and referrals are provided.

    2007-01-01

    Background Traumatic perforation of the distal oesophagus due to blunt trauma is a very rare condition and is still associated with a significant morbidity and mortality. This is further exacerbated by delayed diagnosis and management as symptoms and signs are often masked by or ascribed to more common blunt thoracic injuries. Case report We present a case of a distal oesophageal perforation, secondary to a fall from a third storey window, which was masked by concomitant thoracic injuries and missed on both computed tomography imaging and laparotomy. The delay in his diagnosis significantly worsened the patient's recovery by allowing the development of an overwhelming chest sepsis that contributed to his death. Conclusion Early identification of an intrathoracic oesophageal perforation requires deliberate consideration and is essential to ensure a favorable outcome. Treatment should be individualised taking into account the nature of the oesophageal defect, time elapsed from injury and the patient's general condition. PMID:17374175

    2012-11-01

    Spontaneous urinary bladder perforation is a rare and life-threatening condition similar to traumatic and iatrogenic perforation. The connection with the underlying bladder damage due to previous radiotherapy, inflammation, malignancy, obstruction, or other causes can be found in almost all cases. The symptoms are often nonspecific, and misdiagnosis is common. Here, we present a case of spontaneous urinary bladder perforation due to bladder necrosis in a diabetic woman. She presented to the emergency department with abdominal pain. Exploratory laparotomy was performed by surgeons and revealed necrosis of the anterior and lateral walls of the urinary bladder. Microscopic examination revealed necrotic changes throughout the bladder wall. Ghost-like cellular outlines were compatible with coagulative necrosis. Clusters of bacteria were also present in some necrobiotic tissues. Malignant cells were not present. It appears probable that the infection was due to local interference with the blood supply (arterial, capillary, or venous) combined with the systemic metabolic upset that led to the bladder condition. In our case, we observed partial necrosis of the bladder rather than distortion of the entire blood supply to the bladder as consequences of the microvascular effects of diabetes. Urinary bladder perforation must be considered in the differential diagnosis of patients presenting with free fluid in the abdomen/peritonitis, decreased urine output, and hematuria, and in whom increased levels of urea/creatinine are detected in serum and/ or peritoneal fluid aspirate.

  18. Short bowel syndrome.

    The short bowel syndrome is a symptom complex that occurs in adults who have less than 200 cm of jejunum-ileum remaining after intestinal resection. Similar symptoms are observed in infants and children following massive bowel resection or congenital anomalies and in individuals with longer segments of intestine with severe mucosal disease. Initial care should focus on a thorough excision of nonviable bowel, an exact measurement of the remaining viable bowel, placing all intestine in continuity at the initial or subsequent operation, and controlling initial food intake. With time, adaptation of the remnant intestine occurs, and absorptive function may be maximized by enhancing the enteral diet and minimizing parenteral nutrition. Growth factors and specialized nutrients may also enhance this process. Intestinal transplantation should be considered in selected individuals with the short bowel syndrome who fail intestinal rehabilitation protocols.

    Inflammatory bowel disease is an important cause of gastrointestinal pathology in children and adolescents. The incidence of pediatric inflammatory bowel disease is increasing; therefore, it is important for the clinician to be aware of the presentation of this disease in the pediatric population. Laboratory tests, radiology studies, and endoscopic procedures are helpful in diagnosing inflammatory bowel disease and differentiating between Crohn’s disease and ulcerative colitis. Once diagnosed, the goal of medical management is to induce remission of disease while minimizing the side effects of the medication. Specific attention needs to be paid to achieving normal growth in this susceptible population. Surgical management is usually indicated for failure of medical management, complication, or malignancy. Algorithms for diagnostic evaluation and treatment of pediatric inflammatory bowel disease are presented. The specific psychosocial issues facing these patients are also discussed in this review as are the future goals of research in the complex problem of pediatric inflammatory bowel disease.

    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.

    2016-01-01

    Background: Typhoid perforation ileitis is a serious complication of typhoid fever, a common and unfortunate health problem in a resource-poor country like Nigeria. Following bowel perforation, treatment is usually by simple closure or bowel resection and anastomosis after adequate aggressive fluid resuscitation and electrolyte correction. Postoperatively, some of these patients do require management in Intensive Care Unit (ICU) on account of sepsis or septic shock and to improve survival. Patients and Methods: This is a prospective observational study in which 67 consecutive patients who had exploratory laparotomy for typhoid perforation between August 2009 and October 2012 in the main operating theatre of the University College Hospital, Ibadan, were studied. The attending anaesthetists had the freedom of choosing the appropriate anaesthetic drugs depending on the patients’ clinical condition. The reason for admission into the ICU, the types of organ support required and outcomes were recorded. Results: Twenty-five patients (37.3%) out of 67 required critical care. Reasons for admission among others included poor respiratory effort, hypotension, septic shock and delayed recovery from anaesthesia. Twenty-one patients (84%) required mechanical ventilation with a mean duration of 2.14 days (range 1–5 days). Fourteen patients required ionotropic support and the length of ICU stay ranged from 1 to 15 days (mean 4.32 days). Nineteen patients (76%) were successfully managed and discharged to the ward while 24% (6 patients) mortality rate was recorded. Conclusion: This study showed high rate of post-operative ICU admission in patients with typhoid perforation with a high demand for critical care involving mechanical ventilation and ionotropic support. In centres that manage patients presenting with typhoid ileitis and perforation, post-operative critical care should be available. PMID:28051046

    Small bowel adenocarcinomas (SBAs) are rare tumors, but their incidence is increasing. The most common primary location is the duodenum. Even though SBAs are more often sporadic, some diseases are risk factors. Early diagnosis of small bowel adenocarcinoma remains difficult, despite significant radiologic and endoscopic progress. After R0 surgical resection, the main prognostic factor is lymph node invasion. An international randomized trial (BALLAD [Benefit of Adjuvant Chemotherapy For Small Bowel Adenocarcinoma] study) will evaluate the benefit of adjuvant chemotherapy. For metastatic disease, retrospectives studies suggest that platinum-based chemotherapy is the most effective treatment. Phase II studies are ongoing to evaluate targeted therapy in metastatic SBA.

    Superficial ulnar artery is a rare finding but shows significant surgical implications. Its thinness and pliability make this flap an excellent solution for soft tissue reconstruction, especially in the head and neck region. We hereby report a successful free superficial ulnar artery perforator forearm flap transfer for tongue reconstruction. A 64-year-old man presenting with a squamous cell carcinoma of the left tongue underwent a wide resection of the tumor, left radical neck dissection, and reconstruction of the tongue and the left tonsillar pillar with the mentioned flap. No complications were observed postoperatively. The flap survived completely; no recurrence at 6 months of follow-up was detected. Superficial ulnar artery perforator flap has shown to be a safe alternative to other free tissue flaps in specific forearm anatomic conditions.

    The medial sural artery supplies the medial gastrocnemius muscle and sends perforating branches to the skin. The possible use of these musculocutaneous perforators as the source of a perforator-based free flap was investigated in cadavers. Ten legs were dissected, and the topography of significant perforating musculocutaneous vessels on both the medial and the lateral gastrocnemius muscles was recorded. A mean of 2.2 perforators (range, 1 to 4) was noted over the medial gastrocnemius muscle, whereas in only 20 percent of the specimens was a perforator of moderate size noted over the lateral gastrocnemius muscle. The perforating vessels from the medial sural artery clustered about 9 to 18 cm from the popliteal crease. When two perforators were present (the most frequent case), the perforators were located at a mean of 11.8 cm (range, 8.5 to 15 cm) and 17 cm (range, 15 to 19 cm) from the popliteal crease. A series of six successful clinical cases is reported, including five free flaps and one pedicled flap for ipsilateral lower-leg and foot reconstruction. The dissection is somewhat tedious, but the vascular pedicle can be considerably long and of suitable caliber. Donor-site morbidity was minimal because the muscle was not included in the flap. Although the present series is short, it seems that the medial sural artery perforator flap can be a useful flap for free and pedicled transfer in lower-limb reconstruction.

    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.

  10. Role of uterine forces in intrauterine device embedment, perforation, and expulsion

    Goldstuck, Norman D; Wildemeersch, Dirk

    2014-01-01

    Background 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. Methods 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. Results 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. Conclusion 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. PMID:25143756

  11. Multicentre, open-label, randomised, parallel-group, superiority study to compare the efficacy of octreotide therapy 40 mg monthly versus standard of care in patients with refractory anaemia due to gastrointestinal bleeding from small bowel angiodysplasias: a protocol of the OCEAN trial

    PubMed Central

    van Geenen, E J M; Drenth, J P H

    2016-01-01

    Introduction Gastrointestinal angiodysplasias are an important cause of difficult-to-manage bleeding, especially in older patients. Endoscopic coagulation of angiodysplasias is the mainstay of treatment, but may be difficult for small bowel angiodysplasias because of the inability to reach them for endoscopic intervention. Some patients are red blood cell (RBC) transfusion dependent due to frequent rebleeding despite endoscopic treatment. In small cohort studies, octreotide appears to decrease the number of bleeding episodes in patients with RBC transfusion dependency due to gastrointestinal angiodysplasias. This trial will assess the efficacy of octreotide in decreasing the need for RBC transfusions and parenteral iron in patients with anaemia due to gastrointestinal bleeding of small bowel angiodysplasias despite endoscopic intervention. Study design Randomised controlled, superiority, open-label multicentre trial. Participants 62 patients will be included with refractory anaemia due to small bowel angiodysplasias, who are RBC transfusion or iron infusion dependent despite endoscopic intervention and oral iron supplementation. Intervention Patients will be randomly assigned (1:1) to standard care or 40 mg long-acting octreotide once every 4 weeks for 52 weeks, in addition to standard care. The follow-up period is 8 weeks. Main outcome measures The primary outcome is the difference in the number of blood and iron infusions between the year prior to inclusion and the treatment period of 1 year. Important secondary outcomes are the per cent change in the number of rebleeds from baseline to end point, adverse events and quality of life. Ethics and dissemination The trial received ethical approval from the Central Committee on Research Involving Human Subjects and from the local accredited Medical Research Ethics Committee of the region Arnhem-Nijmegen, the Netherlands (reference number: 2014-1433). Results will be published in a peer-reviewed journal and

    Ramlee, R A; Whitworth, J

    2001-09-01

    Problems can be encountered inserting intraosseous injection needles through perforation sites. This in vitro study examined the variability and size compatibility of Stabident intraosseous injection components. The diameters of 40 needles and perforators from a single Stabident kit were measured in triplicate with a toolmakers microscope. One-way ANOVA revealed that mean needle diameter (0.411 mm) was significantly narrower than mean perforator diameter (0.427 mm) (p < 0.001). A frequency distribution plot revealed that needle diameter followed a normal distribution, indicating tight quality control during manufacture. The diameter of perforators was haphazardly distributed, with a clustering of 15% at the lower limit of the size range. However on no occasion was the diameter of a perforator smaller than that of an injection needle. We conclude that components of the Stabident intraosseous anaesthetic system are size-compatible, but there is greater and more haphazard variability in the diameter of perforators than injection needles.

    For the successful reconstruction of facial defects, various perforator flaps have been used in single-stage surgery, where tissues are moved to adjacent defect sites. Our group successfully performed perforator flap surgery on 17 patients with small to moderate facial defects that affected the functional and aesthetic features of their faces. Of four complicated cases, three developed venous congestion, which resolved in the subacute postoperative period, and one patient with partial necrosis underwent minor revision. We reviewed the literature on freestyle perforator flaps for facial defect reconstruction and focused on English articles published in the last five years. With the advance of knowledge regarding the vascular anatomy of pedicled perforator flaps in the face, we found that some perforator flaps can improve functional and aesthetic reconstruction for the facial defects. We suggest that freestyle facial perforator flaps can serve as alternative, safe, and versatile treatment modalities for covering small to moderate facial defects.

    Introduction Emergency large bowel surgery (ELBS) is known to carry an increased risk of morbidity and mortality. Previous studies have reported morbidity and mortality rates up to 14.3%. However, there has not been a recent study to document the outcomes of ELBS following several major changes in surgical training and provision of emergency surgery. The aim of this study was therefore to explore the current outcomes of ELBS. Methods A retrospective review was performed of a prospectively maintained database of the clinical records of all patients who had ELBS between 2006 and 2013. Data pertaining to patient demographics, ASA (American Society of Anesthesiologists) grade, diagnosis, surgical procedure performed, grade of operating surgeon and assistant, length of hospital stay, postoperative complications and in-hospital mortality were analysed. Results A total of 202 patients underwent ELBS during the study period. The mean patient age was 62 years and the most common cause was colonic carcinoma (n=67, 33%). There were 32 patients (15.8%) who presented with obstruction and 64 (31.7%) had bowel perforation. The overall in-hospital mortality rate was 14.8% (n=30). A consultant surgeon was involved in 187 cases (92.6%) as either first operator, assistant or available in theatre. Conclusions ELBS continues to carry a high risk despite several major changes in the provision of emergency surgery. Further developments are needed to improve postoperative outcomes in these patients. PMID:25723694

  1. Viscous damping of perforated planar micromechanical structures

    The paper gives an analytical approximation to the viscous damping coefficient due to the motion of a gas between a pair of closely spaced fluctuating plates in which one of the plates contains a regular system of circular holes. These types of structures are important parts of many microelectromechanical devices realized in MEMS technology as microphones, microaccelerometers, resonators, etc. The pressure satisfies a Reynolds’ type equation with coefficients accounting for all the important effects: compressibility of the gas, inertia and possibly slip of the gas on the plates. An analytical expression for the optimum number of circular holes which assure a minimum value of the total damping coefficient is given. This value realizes an equilibrium between the squeeze-film damping and the viscous resistance of the holes. The paper also provides analytical design formulas to be used in the case of regular circular perforated plates. PMID:19365579

    Since perforated peptic ulcer is uncommon in children proton pump inhibitor prophylaxis is not routinely recommended when children are treated with high dose steroids. We describe a case of perforated ulcer in a six-year-old patient with nephrotic syndrome treated with high dose prednisolone. Initially, ulcer was not suspected due to uncharacteristic symptoms. The child developed peritoneal signs and surgery revealed a perforated peptic ulcer in the stomach. We recommend treatment with proton pump inhibitors if children, who are treated with high dose steroids develop abdominal symptoms, which can be caused by an ulcus.

    Here, we report two patients with a traumatic intraperitoneal bladder dome rupture repaired by laparoscopic intracorporeal sutures. The first patient was a 3-year old boy was admitted with a history of road accident. He had a traumatic lesion on his lower abdomen and a pelvic fracture. Computed tomography (CT) scan revealed free intraabdominal fluid. The urethragram showed spreading contrast material into the abdominal cavity. Laparoscopic exploration revealed a 3-cm-length perforation at the top of the bladder. The injury was repaired in a two fold fashion. Post-operative follow-up was uneventful. The second case was a 3-year-old boy fell from the second floor of his house on the ground. He had traumatic lesion on his lower abdomen and a pelvic fracture. Due to bloody urine drainage, a cystography was performed and an extravasation from the dome of the bladder into the peritoneum was detected. On laparoscopy, a 3-cm long vertical perforation at the dome of the bladder was found. The perforation was repaired in two layers with intracorporeal suture technique. The post-operative course was uneventful. Laparoscopic repair of traumatic perforation of the bladder dome is a safe, effective and minimally invasive method. The cosmetic outcome is superior.

    Miniaturized cantilevers are one of the elementary structures that are widely used in many micro-devices and systems. The dynamic performance of micro-cantilevers having process dictated through perforations is investigated. High-aspect ratio, long silicon cantilevers, intended for improved performance through lowered stiffness are designed with a series of through holes and simulated along with similar nonperforated/solid cantilevers for comparison. A few perforated structures are also fabricated using silicon-on-insulator-based multiproject MEMS processes from MEMSCAP Inc. (Durham, North Carolina) by reduced mask level and eliminating complex substrate trenching step. The dynamic behavior of these fabricated structures is experimentally studied for both in-plane and out-of-plane directions. It is shown that, due to the presence of perforations, stiffness in planar direction is lightly affected, whereas in out-of-plane direction it is significantly reduced by >35%. Similarly, the variation of damping in both perforated and nonperforated beams, too, is thoroughly analyzed for the first few modes of vibration. Nevertheless, their frequency response variation of <10% for modal frequencies in both planar and out-of-plane directions as compared to the nonperforated counterparts, points to potential applications in several micro-systems including those based on comb drives.

    2015-01-01

    Acute appendicitis is one of the most common causes of acute abdominal pain. Accurate diagnosis is often hindered due to various presentations that differ from the typical signs of appendicitis, especially the position of the appendix. A delay in diagnosis or treatment may result in increased risks of complications, such as perforation, which is associated with increased morbidity and mortality rates. Necrotizing fasciitis caused by perforated appendicitis is extremely rare. We herein report a case of 50-year-old man presenting with an appendiceal abscess in local hospital. After ten days of conservative treatment with intravenous antibiotics, the patient complained about pain and swelling of the right lower limb and computed tomography (CT) demonstrated a perforated appendix and gas and fluid collection extending from his retroperitoneal cavity to the subcutaneous layer of his right loin and right lower limb. He was transferred to our hospital and was diagnosed with necrotizing fasciitis caused by perforated appendicitis. Emergency surgery including surgical debridement and appendectomy was performed. However, the patient died of severe sepsis and multiple organ failure two days after the operation. This case represents an unusual complication of a common disease and we should bear in mind that retroperitoneal inflammation and/or abscesses may cause necrotizing fasciitis through lumbar triangles.

    Incompetent superficial veins are the most common cause of lower extremity superficial venous reflux and varicose veins; however, incompetent or insufficient perforator veins are the most common cause of recurrent varicose veins after treatment, often unrecognized. Perforator vein insufficiency can result in pain, skin changes, and skin ulcers, and often merit intervention. Minimally invasive treatments have replaced traditional surgical treatments for incompetent perforator veins. Current minimally invasive treatment options include ultrasound guided sclerotherapy (USGS) and endovascular thermal ablation (EVTA) with either laser or radiofrequency energy sources. Advantages and disadvantages of each modality and knowledge on these treatments are required to adequately address perforator venous disease. PMID:28123979

    Perforation of esophagus in the adult is a very morbid condition with high morbidity and mortality. The ideal treatment is controversial. The main causes for esophageal perforation in adults are iatrogenic, traumatic, spontaneous and foreign bodies. The morbidity and mortality rate is directly related to the delay in diagnosis and initiation of optimum treatment. The reported mortality from treated esophageal perforation is 10% to 25%, when therapy is initiated within 24 hours of perforation, but it could rise up to 40% to 60% when the treatment is delayed beyond 48 hours. Primary closure of the perforation site and wide drainage of the mediastinum is recommended if perforation is detected in less than 24 hours. Treatment option for delayed or missed rupture of esophagus is not very clear and is controversial. Recently a substantial number of patients with esophageal perforation are being managed by nonoperative measures. Patients with small perforations and minimal extraesophageal involvement may be better managed by nonoperative treatment Major prognostic factors determining mortality are the etiology and site of the injury, the presence of underlying esophageal pathology, the delay in diagnosis and the method of treatment. For optimum outcome for management of esophageal perforations in adults a multidisciplinary approach is needed. PMID:27942303

    Laparoscopic cholecystectomy for acute cholecystitis and cholelithiasis is one of the most common operations performed in the United States. Inadvertent perforation and spillage of gallbladder contents are not uncommon. The potential impact of subsequent retained gallstones is understated. We present the case of an intraperitoneal gallstone retained from a previous cholecystectomy eroding into the bowel and leading to intraluminal mechanical bowel obstruction requiring operative intervention. This case illustrates the potential risks of retained gallstones and reinforces the need to diligently collect any dropped stones at the time of initial operation. PMID:27703833

    Introduction: Adhesions are the reason for bowel obstruction in 80% of the cases. In well selected patients the adhesive ileus laparoscopic treatment has multiple advantages which include the shorter hospitalization period, earlier food taking, and less postoperative morbidity rate. Case report: Here we have a patient in the age of 35 hospitalized at the clinic due to occlusive symptoms. Two years before an opened appendectomy had been performed on him. He underwent the treatment of exploration laparoscopy and laparoscopic adhesiolysis. Dilated small bowel loops connected with the anterior abdominal wall in the ileocecal region by adhesions were found intraoperatively and then resected harmonically with scalpel. One strangulation around which a small bowel loop was wrapped around was found and dissected. Postoperative course was normal. PMID:27041815

    Many of the ophthalmic surgical instruments are extremely fine and sharp. Due to the dim light environment required for ophthalmic surgical procedures, the passing of sharp instruments among surgeons and scrub nurses also poses a risk for glove perforations. A case-control study was performed to determine the number and site of perforations in the surgical gloves used by a group of scrub nurses during ophthalmic surgery. All six nurses working in an eye and refractive surgery centre in Hong Kong participated in the study. A total of 100 (50 pairs) used surgical gloves were collected following 50 ophthalmic surgeries. Fifty pairs of new surgical gloves were also collected. Every collected surgical glove underwent the water leak test. The surgical procedure perforation rate was 8%, and none of the perforations were detected by the scrub nurses. No perforations were found in any unused gloves. The findings indicate that glove perforations for scrub nurses during ophthalmic surgery do occur and mostly go unnoticed. Future studies should continue to explore factors contributing to surgical glove perforation.

    Introduction: Colonic perforation is a clinical condition which occurs due to variety of reasons, such as intrinsic disorders of the intestine, extrinsic causes, but also due to presence of foreign bodies. Foreign objects enter gastrointestinal tract by oral or transanal introduction. Case report: we present an uncommon case of a 26- year-old tetraplegic male, whose death was a consequence of a widespread purulent peritonitis provoked by colonic perforation inflicted by an unusual foreign body, transanally introduced 28 centimeters long zucchini (Cucurbita pepo L.). Conclusions: we share our experience in order to emphasize the importance of consideration and early recognition of foreign body presence in the alimentary tract as possible diagnosis. PMID:27994305

    Mesenteric venous thrombosis is a rare cause of intestinal ischemia which is potentially life-threatening because it can lead to intestinal infarction. Mesenteric venous thrombosis rarely develops after abdominal surgery and is usually associated with coagulation disorders. Associated symptoms are generally subtle or nonspecific, often resulting in delayed diagnosis. A 68-year-old woman underwent laparoscopic exploration for small bowel obstruction, secondary to adhesions. During the procedure, an intestinal perforation was identified and repaired. Postoperatively, the abdominal pain persisted and repeat exploration was undertaken. At repeat exploration, a perforation was identified in the small bowel with a surrounding abscess. After the second operation, the abdominal pain improved but anorexia persisted. Contrast enhanced abdominal computed tomography was performed which revealed superior mesenteric venous thrombosis. Anticoagulation therapy with heparin was started immediately and the thrombus resolved over the next 6 days. Although rare, this complication must be considered in patients after abdominal surgery with unexplained abdominal symptoms. PMID:24455391

    A case of gallbladder perforation is presented in which a small bile leak was demonstrated by cholescintigraphy while the patient was receiving meperidine, but not after meperidine was discontinued. The scintigrams obtained during meperidine therapy also showed a pattern of bile-duct obstruction. It is suggested that increased biliary pressure secondary to meperidine admininstration permitted visualization of the leak. Use of narcotic drugs may be a useful pharmocologic intervention in cases of peritonitis due to small obscure bile leaks.

    Trichobezoars are an uncommon cause of acute abdominal pain. We present a case of a 12-year-old girl with a history of a trichobezoar who presented to the emergency department with acute abdominal pain. Abdominal sonography was performed which suggested portal venous gas and showed complex peritoneal fluid. Subsequent computed tomography demonstrated both gastric and small bowel bezoars, with a jejunojejunal intussusception, and confirmed portal venous gas and complex ascites. At the time of surgery, there was evidence of intestinal and biliary perforation. Our case illustrates a constellation of complications in association with a long-standing trichobezoar.

    Percutaneous radiofrequency ablation (RFA) has gained wide acceptance as nephron-sparing therapy for small renal masses in select patients. Generally, it is a safe procedure with minor morbidity and acceptable short-term oncologic outcome. However, as a result of the close proximity of vital structures, such as the bowel, ureter, and large vessels, to the ablative field, complications regarding these structures may occur. This is the first article describing appendiceal perforation as a complication of computed tomography-guided RFA despite hydrodissection. When performing this innovative and promising procedure one should be aware of the possibility of particular minor and even major complications.

  1. Position paper: management of perforated sigmoid diverticulitis

    PubMed Central

    2013-01-01

    Over the last three decades, emergency surgery for perforated sigmoid diverticulitis has evolved dramatically but remains controversial. Diverticulitis is categorized as uncomplicated (amenable to outpatient treatment) versus complicated (requiring hospitalization). Patients with complicated diverticulitis undergo computerized tomography (CT) scanning and the CT findings are used categorize the severity of disease. Treatment of stage I (phlegmon with or without small abscess) and stage II (phlegmon with large abscess) diverticulitis (which includes bowel rest, intravenous antibiotics and percutaneous drainage (PCD) of the larger abscesses) has not changed much over last two decades. On the other hand, treatment of stage III (purulent peritonitis) and stage IV (feculent peritonitis) diverticulitis has evolved dramatically and remains morbid. In the 1980s a two stage procedure (1st - segmental sigmoid resection with end colostomy and 2nd - colostomy closure after three to six months) was standard of care for most general surgeons. However, it was recognized that half of these patients never had their colostomy reversed and that colostomy closure was a morbid procedure. As a result starting in the 1990s colorectal surgical specialists increasing performed a one stage primary resection anastomosis (PRA) and demonstrated similar outcomes to the two stage procedure. In the mid 2000s, the colorectal surgeons promoted this as standard of care. But unfortunately despite advances in perioperative care and their excellent surgical skills, PRA for stage III/IV diverticulitis continued to have a high mortality (10-15%). The survivors require prolonged hospital stays and often do not fully recover. Recent case series indicate that a substantial portion of the patients who previously were subjected to emergency sigmoid colectomy can be successfully treated with less invasive nonoperative management with salvage PCD and/or laparoscopic lavage and drainage. These patients

    Introduction Gall bladder perforation is associated with high mortality rates and therefore must be recognised and managed promptly. We present an unusual presentation of spontaneous gall bladder perforation. Case presentation An elderly lady with multiple medical co-morbidities was admitted with sepsis following a fall. Initial assessment lead to a diagnosis of pneumonia, however a rapidly expanding right flank mass was incidentally noted during routine nursing care. Imaging studies were inconclusive, however incision and drainage of the mass revealed bile stained pus draining cutaneously from an acutely inflamed gallbladder. The patient made a good recovery following surgery, and was discharged with outpatient follow-up. Discussion Despite focussed post-hoc history taking she denied any prodromal symptoms of cholecystitis. In addition to reporting an unusual cause for a common presentation, we highlight the importance of a full body examination in the context of sepsis, regardless of whether the source has been identified. In addition, we advocate that surgical intervention in sepsis should not be delayed by imaging in cases where an abscess is suspected. Conclusions Percutaneous abscesses arising from the gallbladder are a rare but potentially serious consequence of acute cholecystitis, and may present in a wide variety of locations. Therefore it is imperative to conduct a full body inspection in the septic patient, even when a source has been identified. PMID:26686488

    The application of extreme overbalance perforating, by Oryx Energy Co., is consistently outperforming the unpredictable, tubing-conveyed, underbalance perforating method which is generally accepted as the industry standard. Successful results reported from more than 60 Oryx Energy wells, applying this technology, support this claim. Oryx began this project in 1990 to address the less-than-predictable performance of underbalanced perforating. The goal was to improve the initial completion efficiency, translating it into higher profits resulting from earlier product sales. This article presents the concept, mechanics, procedures, potential applications and results of perforating using overpressured well bores. The procedure can also be used in wells with existing perforations if an overpressured surge is used. This article highlights some of the case histories that have used these techniques.

    2015-02-25

    We report a strikingly unusual case of traumatic intraperitoneal perforation of an augmented bladder from clean intermittent self-catheterisation (CISC), which presented a unique diagnostic challenge. This case describes a 48-year-old T1 level paraplegic, who had undergone clamshell ileocystoplasty for detrusor overactivity, presenting with abdominal distension, vomiting and diarrhoea. Initial investigations were suggestive of disseminated peritoneal malignancy with ascitic fluid collections, but the ascitic fluid was found to be intraperitoneal urine from a perforation of the urinary bladder. This was associated with an inflammatory response in the surrounding structures causing an appearance of colonic thickening and omental disease. Although the diagnostic process was complex due to this patient's medical history, the treatment plan initiated was non-operative, with insertion of an indwelling urinary catheter and radiologically guided drainage of pelvic and abdominal collections. Overdistension perforations of augmented urinary bladders have been reported, but few have described perforation from CISC.

    Subclavian artery (SCA) perforation is a rare complication while performing SCA intervention. In our present report, a 73-year-old female, with stenosis of the left SCA and situs inversus, presented with exercise-induced left arm weakness. The SCA stenosis was treated with direct stenting with a balloon-expansible Express LD 10×25 mm stent. However, it caused iatrogenic SCA perforation and hemothorax. The perforation was sealed by endovascular repair with operator-modified Endurant II graft stent, which complicated with occlusion of left common carotid artery. And, the carotid artery was rescued by another stent. The graft stent, which was originally designed for abdominal aortic aneurysm, can be modified to suitable length and take as a rescue stent of large vessel with iatrogenic perforation. Due to strong radial force of graft stent, preservation of large side branches should been watched out. PMID:28120581

    Henoch-Schönlein purpura (HSP) is generally a self-limited vasculitis disease and has a good prognosis. We report a 4-year-old Thai boy who presented with palpable purpura, abdominal colicky pain, seizure, and eventually developed intestinal ischemia and perforation despite adequate treatment, including corticosteroid and intravenous immunoglobulin therapy. Imaging modalities, including ultrasonography and contrast-enhanced computed tomography, could not detect intestinal ischemia prior to perforation. In this patient, we also postulated that vasculitis-induced mucosal ischemia was a cause of the ulcer, leading to intestinal perforation, and high-dose corticosteroid could have been a contributing factor since the histopathology revealed depletion of lymphoid follicles. Intestinal perforation in HSP is rare, but life-threatening. Close monitoring and thorough clinical evaluation are essential to detect bowel ischemia before perforation, particularly in HSP patients who have hematochezia, persistent localized abdominal tenderness and guarding. In highly suspicious cases, exploratory laparotomy may be needed for the definite diagnosis and prevention of further complications. PMID:27468201

  9. Outcome of 22 cases of perforated tympanic membrane caused by otomycosis.

    PubMed

    Hurst, W B

    2001-11-01

    Twenty-two cases of perforated tympanic membrane due to fungal otitis externa were observed over a five-year period. The diagnosis of fungal otitis externa was made on clinical grounds due to the obvious presence of fungal bloom in the external ear canal. Some perforations were noted at the first treatment after the fungal debris had been removed from the external ear canal using a microscope. Other perforations were observed to develop over a few days. Initially, a discrete area of the tympanic membrane appeared white and opaque. As time progressed the white area disintegrated, forming a perforation. Once the otitis externa had resolved most perforations healed spontaneously. Two that were observed to develop during treatment required a myringoplasty. Another one closed significantly but a tiny persistent perforation required cauterization with trichloracetic acid to encourage it to close over completely. The only residual hearing loss was in a case with almost total disintegration of the tympanic membrane requiring a myringoplasty. Treatment of fungal otitis externa for the patients in this series was aural toilet using suction under a microscope and insertion of a gauze wick saturated in a combination of hydrocortisone, clotrimazole, framycetin and gramicidin.

    Mechanical bowel preps were initially thought to decrease the bacterial load of the colon and therefore decrease infection. Traditional bowel preps include osmotic, laxative, and combination regimen. Data demonstrate that mechanical bowel preps are generally equivalent; however, the addition of oral antibiotics may further reduce the risk of infection. Recent data suggest that mechanical bowel preparations may not be necessary, and that dietary restrictions before surgery may also be obsolete. In this review, the authors address the types of mechanical bowel preparations (MBPs), differences in outcomes between MBPs, the role of oral antibiosis and enemas, the benefits of no MBP, and dietary preparations for elective colon and rectal surgery.

    The principal aim of this review is to present the current knowledge regarding acute otitis media (AOM) with spontaneous tympanic membrane perforation (STMP) and to address the question of whether AOM with STMP is a disease with specific characteristics or a severe case of AOM. PubMed was used to search for all studies published over the past 15 years using the key words "acute otitis media" and "othorrea" or "spontaneous tympanic membrane perforation". More than 250 articles were found, but only those published in English and providing data on aspects related to perforation of infectious origin were considered. Early Streptococcus pneumoniae infection due to invasive pneumococcal strains, in addition to coinfections and biofilm production due mainly to non-typeable Haemophilus influenzae, seem to be precursors of STMP. However, it is unclear why some children have several STMP episodes during the first years of life that resolve without complications in adulthood, whereas other children develop chronic suppurative otitis media. Although specific aetiological agents appear to be associated with an increased risk of AOM with STMP, further studies are needed to determine whether AOM with STMP is a distinct disease with specific aetiological, clinical and prognostic characteristics or a more severe case of AOM than the cases that occur without STMP. Finally, it is important to identify preventive methods that are useful not only in otitis-prone children with uncomplicated AOM, but also in children with recurrent AOM and those who experience several episodes with STMP.

  12. Managing bleeding, fluid absorption and uterine perforation at hysteroscopy.

    Hysteroscopy is the current gold standard for evaluating intrauterine pathology, including submucous fibroids, polyps, hyperplasia and cancer. However, there are still problems and complications connected to hysteroscopy. Fluid overload of 1-2l occurs in approximately 5.2% and >2l in 1% of cases. This article discusses the physiology, implications and treatment of these cases. Uterine perforation is encountered in nearly 1% of cases. We describe the precautions to avoid this perforation and the methods to treat it. The article also discusses excessive bleeding, which occurs in 3% of operative hysteroscopies and describes strategies to avoid and to deal with this complication. Emergency hysterectomy and other surgical interventions are rarely indicated and are seen in 2% of cases. Finally, death due to septicaemia or fluid overload has been reported only very rarely (0.1%). These different complications are discussed in detail.

    A 43-year-old man presented to the hospital with haemoptysis. When worked up, his history and examination were highly suggestive of pulmonary tuberculosis (TB). He subsequently developed a massive upper gastrointestinal bleed and underwent an emergency laparotomy, which revealed a massively dilated caecum measuring ∼20 cm in diameter. The caecum had perforated due to acute decompensation of intestinal TB. Though common in developing countries, TB is rare in the UK, especially the intestinal kind. The most striking feature of this case is, however, the size of the caecal distension caused by the tubercular inflammation and subsequent perforation—something unheard of in the literature. This massive caecal distention would be explained by the Law of Laplace. In conclusion, massive distension and caecal perforation are possible consequences of intestinal TB, especially in the 48–72 h immediately after starting anti-tubercular therapy. PMID:25972412

    Lens damage is present in 30% of perforating injuries of the anterior segment of the eye. There is no consensus on whether the cataractous lens should be removed at the initial repair of the corneal laceration or later, when the eye has recovered from injury. Twenty-seven consecutive cases with a perforating corneal injury and lens damage were alternatively treated either with simultaneous corneal suturing and cataract removal or with corneal suturing and delayed cataract removal several weeks later. The difference in the frequency of complications between the 2 groups was significant. The 1-step procedure was technically easier to perform, the period of postoperative irritation was shorter, complications due to the presence of an injured lens were prevented, and visual rehabilitation occurred earlier.

    2016-01-01

    Introduction Ileal perforations are a common place of occurrence in emergency operation rooms around India. They are also significant contributors to mortality in our country. They are very distressing for patients because of the high morbidity of a laparotomy and in certain cases a stoma if its necessity is felt by the operating surgeon. The nature of the disease itself predisposes to a number of complications including wound infections, faecal fistulas and complications associated with a stoma. Aim To evaluate the role of ileostomy in patients with non-traumatic ileal perforation. Materials and Methods A total of 192 cases of ileal perforation, diagnosed per-operatively, were prospectively studied between June 2012 and July 2014. Cases were treated according to standard resuscitation protocols and underwent repair of the ileal perforation either as primary closure or as a bowel resection and anastomosis with or without a proximal diversion ileostomy. Cases were followed up for a period of six months and immediate and late complications and outcomes were noted. Results A total of 192 patients were studied during the given study period out of which 170 (88.5%) were males. The disease was treated primarily without diversion stoma in 176 patients and in 16 patients a proximal diversion ileostomy was performed. The overall mortality was 15 (7.8%) that was noted to be not significantly different in patients with respect to the performance of a stoma. Enterocutaneous fistula was a complication seen exclusively in the non-ileostomy group whereas stomal complications were expectedly noted only in the stoma group. Conclusion The authors found that though conventional ileostomy diversion may appear a safe option in patients with ileal perforations, it has its own additional morbidity, which at times can be very difficult to manage. An ileostomy is of use in a very small group of patients that is diminishing as better facilities and equipment are obtained to manage this

  16. [Irritable bowel syndrome].

    1994-04-01

    Irritable bowel is a functional gastrointestinal disorder with chronic or relapsing symptoms of abdominal pain and impaired frequency and consistency of the faeces caused by obscure structural or biochemical deviations. The frequency of the condition in civilized countries is estimated to amount to 15-20% of the population and it accounts for 25-50% of all patients in gastroenterological ambulatory departments. From the clinical aspect the type with dominant diarrhoea, typically in the morning and very compelling, and the type with pain and constipation are known but even combinations of the two types are encountered. A psychosomatic disorder of the motility of the large bowel and its tonus is involved associated with enhanced pain perception. Despite great efforts to find aetiopathogenetic factors, knowledge still is at the level of obscure theories. The diagnosis is still established per exclusion after all organic causes are ruled out, i.e. we always have to differentiate between an irritable bowel from an irritated one. In therapy the patient's confidence in his doctor is most important and it is essential to gain the patient's active cooperation. In case of diarrhoea a low-residue diet is used, calcium carbonate, codeine, loperamide, conversely in constipation adequate dietary fibre, intake metoclopramide or cisapride. Pain is relieved by spasmolytics or Ca channel blockers in the smooth musculature of the large bowel. The associated dysbiosis is transformed into eubiosis by Lactobacillus or other bacterial products.

    Case series Patients: Female, 11 • Male, 15 Final Diagnosis: Spontaneous gastric perforation Symptoms: Abdominal pain • distention • vomiting • leukocytosis Medication: — Clinical Procedure: Both patients had surgery Specialty: Gastroenterology Objective: Rare etiology Background: Spontaneous gastric perforation is a rare clinical disorder. The majority of the available data have been reported in the neonatal age group. There are a few cases of spontaneous gastric perforation in preschool children. To our knowledge, there is no published information on spontaneous gastric perforation in older children and adolescents. Case Report: We describe the presentation and clinical course of two adolescent children who presented with spontaneous gastric perforation. Both children presented with acute onset abdominal pain, which progressively worsened. In both cases, the patient were taken urgently to the operating room after imaging studies had shown pneumoperitoneum. In both cases, surgery revealed gastric perforation with no obvious etiology, specifically no ulcer, inflammation, or other pathology. Conclusions: These two cases highlight the importance of including spontaneous gastric perforation, not just the typical duodenal/gastric ulcer, in the differential of a patient with severe abdominal pain and distension, who has imaging showing pneumoperitoneum.

    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.

    Complications of diverticula of the duodenum, jejunum and ileum, exclusive of Meckel's diverticula are extremely rare but can produce major diagnostic and therapeutic problems. Major reported complications include hemorrhage, perforation, biliary and pancreatic obstruction, and inflammation with intestinal obstruction. The mortality of complicated duodenal diverticula is reported from 33 to 48%. Our experience with some of these complications is reported. This experience and a review of other reported cases have led to the following recommendations for surgical treatment. 1) Massively bleeding duodenal diverticulum. Precise localization of the bleeding point by endoscopy and/or arteriography is highly desirable. Excision or partial excision of the diverticulum with suture ligation of the bleeding point is necessary. 2) Perforated duodenal diverticulum. Excision or partial excision, secure closure and drainage are necessary. If peri-Vaterian, a probe should be passed through the ampulla of Vater via the common duct. Unless an entirely satisfactory closure is achieved, complete diversion of the enteric stream from the duodenum by vagotomy, antrectomy with closure of duodenal stump, and Billroth II anastomosis is recommended. 3) Choledochal obstruction due to duodenal diverticulum. Choledocho-duodenostomy. 4) Perforation, bleeding, or obstruction due to jejunal or ileal diverticulum. In rare cases, local excision of the diverticulum is feasible. Usually, resection of the involved segment with primary anastomosis is indicated. ImagesFig. 1.Fig. 2.Fig. 3.Fig. 4.Fig. 5.Fig. 6. PMID:111637

    Intraluminal small bowel hematoma has been rarely reported in children, as a rare cause of small bowel obstruction. We present a case of an intraluminal ileal hematoma presenting as small bowel obstruction in a child. Computed Tomography (CT) indicated a large intraluminal hyperdense lesion in the distal ileum as the cause of small bowel obstruction. Abdominal ultrasonography (US) showed an echogenic mass-like lesion with multiple septa in the distal ileum. Small bowel obstruction due to a complicated cystic mass was provisionally diagnosed. Histopathologic examination of the resected mass suggested a submucosal ileal hematoma. Although intraluminal small bowel hematoma is rare in children, it can present as an intraluminal cystic mass and should be considered as a rare cause of small bowel obstruction. The US and CT findings of submucosal ileal hematoma could be useful for the diagnosis of such cases in the future.

    Fungal microorganisms as a cause of gastric perforation, is very rare. Most of the cases of gastric perforation are seen as the complications of peptic ulcer disease, the intake of NSAIDs (Non Steroidal Anti-Inflammatory Drugs), neoplastic diseases, etc. We are reporting a case of a 50 year old male who presented with a sudden onset of abdominal pain and shock and was diagnosed as acute peritonitis which was caused by a gastrointestinal perforation. An emergency exploratory laporotomy was performed and a gastric perforation repair with omentoplexy was done. However, the patient died in the post operative period due to a sudden cardiac arrest. A gastric perforation edge biopsy revealed the presence of fungal hyphae. The peritoneal fluid culture revealed Candida albicans colonies.

    Introduction Mesh fixation with tacker systems is common in laparoscopic and open hernia repair. Complications due to absorbable tackers are rare and have not been described in the literature. However, we report a case of gallbladder erosion due to tacker dislocation. Methods An open hernia repair was performed using an intraperitoneal onlay mesh for a recurrent parastomal hernia after two previous mesh repairs in a 67-year-old patient. Results On postoperative day 2, the patient was reoperated because of a dislocated tacker that eroded and perforated the fundus region of the gallbladder. Putatively, tacker dislocation occurred owing to imbalanced traction forces. Initially, the mesh was fixed with absorbable tackers around the stoma on the right and transmuscular suture fixation was carried out on the left abdominal side. On revision surgery, tension forces to the right were therefore neutralised by additional transmuscular sutures on the right side. Conclusions Absorbable tackers in open hernia repair provide a safe and effective mesh fixation if tension forces are carefully avoided. PMID:25245719

    Coronary artery perforation remains one of the most fearsome complications during cardiac catheterization procedures. Although emergent bypass surgery is the preferred treatment for cases with uncontrollable perforation, endovascular vessel sealing and arrest of bleeding with a combination of balloons, covered stents, or embolic materials have also been proposed. The authors describe a case of emergent lifesaving microcoil embolization of the distal right coronary artery in a patient with uncontrollable grade III guidewire perforation resulting in cardiac tamponade. The relevant literature is reviewed and the merits and limitations of the endovascular approach are highlighted.

    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.

    Perforated walls find a wide use as a method of flow control and effusive cooling. Experimental investigations of the gas flow past perforated plate with microholes (110μm) were carried out. The wide range of pressure at the inlet were investigated. Two distinguishable flow regimes were obtained: laminar and turbulent regime.The results are in good agreement with theory, simulations and experiments on large scale perforated plates and compressible flows in microtubules. Formulation of the transpiration law was associated with the porous plate aerodynamics properties. Using a model of transpiration flow the “aerodynamic porosity” could be determined for microholes.

    Background Perineal defects are commonly encountered during the treatment of conditions such as malignancy, infectious disease, and trauma. Covering large defects in the perineal area is challenging due to its complicated anatomy and the need for functional preservation. Methods Fourteen patients who underwent reconstructive surgery with multiple perforator flaps for defects >100 cm2 in the perineal area were included in this retrospective cohort study. Characteristics of the perforator flap operation and postoperative outcomes were reviewed. Results Reconstruction was performed using 2 perforator flaps for 13 patients and 3 perforator flaps for 1 patient. Internal pudendal artery perforator flaps were mainly used for covering the defects. The average defect size was 176.3±61.8 cm2 and the average size of each flap was 95.7±31.9 cm2. Six patients had minor complications, such as wound dehiscence and partial necrosis of the flap margin, which were corrected with simple revision procedures. Conclusions Multiple perforator flaps can be used to achieve successful reconstructions of large perineal defects that are difficult to reconstruct with other coverage methods. PMID:27689052

    Capsule endoscopy has revoluzionized the study of the small bowel by providing a reliable method to evaluate, endoscopically, the entire small bowel. In the last six years several papers have been published exploring the possible role of this examination in different clinical conditions. At the present time capsule endoscopy is generally recommended as a third examination, after negative bidirectional endoscopy, in patients with obscure gastrointestinal bleeding. A growing body of evidence suggests also an important role for this examination in other clinical conditions such as Crohn's disease, celiac disease, small bowel polyposis syndromes or small bowel tumors. The main complication of this examination is the retention of the device at the site of a previously unknown small bowel stricture. However there are also some other open issues mainly due to technical limitations of this tool (which is not driven from remote control, is unable to take biopsies, to insufflate air, to suck fluids or debris and sometimes to correctly size and locate lesions). The recently developed double balloon enteroscope, owing to its capability to explore a large part of the small bowel and to take targeted biopsies, although being invasive and time consuming, can overcome some limitations of capsule endoscopy. At the present time, in the majority of clinical conditions (i.e. obscure GI bleeding), the winning strategy seems to be to couple these two techniques to explore the small bowel in a painless, safe and complete way (with capsule endoscopy) and to define and treat the lesions identified (with double balloon enteroscopy).

    Colonic complications are rare after acute pancreatitis but are associated with a high mortality. Possible complications include mechanical obstruction, ischaemic necrosis, haemorrhage, and fistula. We report a case of large bowel obstruction in a 31-year-old postpartum female, secondary to severe gallstone pancreatitis. The patient required emergency laparotomy and segmental bowel resection, as well as cholecystectomy. Presentation of obstruction occurs during the acute episode or can be delayed for several weeks. The most common site is the splenic flexure owing to its proximity to the pancreas. Initial management may be conservative, stenting, or surgical. CT is an acceptable baseline investigation in all cases of new onset bowel obstruction. Although bowel obstruction is a rare complication of pancreatitis, clinicians should be aware of it due to its high mortality. Obstruction can occur after a significant delay following the resolution of pancreatitis. Those patients with evidence of colonic involvement on pancreatic imaging warrant further large bowel evaluation. Bowel resection may be required electively or acutely. Colonic stenting has an increasing role in the management of large bowel obstruction but is a modality of treatment that needs further evaluation in this setting. PMID:27847668

    mesenteric hematoma/fat stranding are the most common CT findings in bowel injuries proven at laparotomy. A small percentage of patients have no abnormal CT findings. This grading system did not prove to be useful in our study likely due to our inherently small patient population; however, the use of BIPS deserves further investigation as it may help in identifying blunt bowel and mesenteric injury patients with often subtle or nonspecific CT findings.

    Wind power is one of the important renewable energy sources. Currently, many researches are focusing on improving the aerodynamic performance of wind turbine blades through simulations and wind tunnel testing. In the present study, the aerodynamic performance of the perforated Eqwin blade (shell type blade) is investigated by using numerical simulation. Three types of slots namely circular, horizontal rectangular and vertical rectangular were evaluated. It was found that the optimum angle of attack for a perforated shell type blade was 12° with maximum Cl/Cd value of 6.420. In general, for all the perforated blade cases, Cl/Cd tended to decrease as the slot size increased except for the circular slot with 5 mm diameter. This was due to the disturbance of the airflow in lower side region which passed through the bigger slot size. Among the modified slots; the circular slot with diameter of 5 mm would be the best slot configuration that can be considered for blade fabrication. The Cl/Cd obtained was 6.46 which is about 5% more than the value of the reference blade. Moreover, the introduced slot would also reduce the overall weight of the blade by 1.3%.

    Sodium polystyrene sulfonate (Kayexalate) and calcium polystyrene sulfonate (CPS, Kalimate) are commonly used to reduce serum potassium. There were some published evidences of severe gastrointestinal complications from the administration of these agents such as colonic necrosis with or without perforation and acute obstruction. The authors reported a 52-year-old male patient being critically ill from severe soft tissue infection of the right leg and sepsis. Hyperkalemia had occurred due to renal insufficiency and required several doses of Kalimate to reduce the serum potassium level. Subsequently, the patient developed complete intestinal obstruction and an exploratory laparotomy was performed. The intra-operative findings were distended stomach and the small bowel contained a large amount of intraluminal affected Kalimate that was removed via gastrotomy and enterotomy. These findings suggested that the inspissated Kalimate could lead to significant obstruction of the gastrointestinal tract in some groups of patient.

    OBJECT The purposes of this study were to evaluate the frequency with which children presented with ventriculoperitoneal (VP) shunt perforations of the gastrointestinal (GI) tract, to determine the type of shunts that caused the perforations, and to compare the stiffness of perforating catheters with the stiffness of catheters from other manufacturers. METHODS Medical records were reviewed of 197 children who were admitted with VP shunt malfunction. Catheter stiffness was evaluated by measuring relative resistance to cross-sectional compression, resistance to column buckling, and elasticity in longitudinal bending. Catheter frictional force was measured per unit length. RESULTS Six children were identified whose VP shunts had perforated the GI tract; 2 shunts subsequently protruded through the anal orifice, 1 protruded through the oral cavity, and 3 presented with subcutaneous abscesses that tracked upward from the intestine to the chest. All perforating shunts were Chhabra shunts. Catheter stiffness and resistance to bending were greatest with a Medtronic shunt catheter, intermediate with a Codman catheter, and least with a Chhabra catheter. Frictional force was greatest with a Chhabra catheter and least with a Medtronic catheter. CONCLUSIONS The frequency of perforations by Chhabra shunts appears to be higher than the frequency associated with other shunts. The increased frequency does not correlate with their stiffness but may reflect their greater frictional forces.

The arteries were injected with latex, and we studied all perforators that extended from the facial artery and headed directly to the oral mucosa. The diameter and length of the facial artery and its mucosal perforators were measured and compared. We found 52 oral mucosal perforators in the 10 facial arteries injected with latex. Their mean (SD) diameter was 0.5 (0.2) mm and the mean (SD) number/facial artery was 5.2 (1.1). Their mean (SD) length was 16.4 (5.3) mm. Most of those to the cheek were localised between the branching-off points of the inferior and superior labial arteries. The facial artery has perforators to the oral mucosa of the cheek, most of them between the points at which the labial arteries emerge.

    Irritable bowel syndrome (IBS) is one of the most frequent functional gastrointestinal disorders. The main symptoms are abdominal pain associated with a change in bowel habit. Headache and psychiatric disorders such as mood or anxiety disorders are often associated with IBS. Genetic predisposition, sensomotoric dysfunction, altered enteric inflammation and immune activation and disturbance of the brain-gut interaction are the most important pathogenetic factors. The diagnosis requires the new symptom-based Rome-III-criteria. Diagnostic testing primarily depends on the patients complaints, clinical and laboratory features and is then guided by the patient's age, symptom's severity and duration, alarm symptoms, psychosocial factors, and the family history for tumors. Treatment of IBS is based on an individualized evaluation and depends on disease severity, predominant symptoms and associated disorders. Treatment options include lifestyle modifications, drug therapy aimed at predominant symptoms and various forms of psychological treatments.

    Gastrointestinal perforation is a serious adverse event that occurs in approximately 1% of patients receiving ramucirumab and paclitaxel. A 67-year-old man with unresectable advanced gastric cancer was admitted to our hospital and treated with ramucirumab and paclitaxel. Gastric perforation occurred during the second cycle of chemotherapy. Although the patient's condition improved without surgery, an abscess developed in the intra-abdominal fluid collection resulting from the perforation. We performed endoscopic ultrasound-guided abscess drainage. The patient improved and was discharged in satisfactory condition. Endoscopic ultrasound-guided drainage is a treatment option for patients with intra-abdominal abscess following gastric perforation due to ramucirumab.

    The short bowel syndrome (SBS) is a state of malabsorption following intestinal resection where there is less than 200 cm of intestinal length. The management of short bowel syndrome can be challenging and is best managed by a specialised multidisciplinary team. A good understanding of the pathophysiological consequences of resection of different portions of the small intestine is necessary to anticipate and prevent, where possible, consequences of SBS. Nutrient absorption and fluid and electrolyte management in the initial stages are critical to stabilisation of the patient and to facilitate the process of adaptation. Pharmacological adjuncts to promote adaptation are in the early stages of development. Primary restoration of bowel continuity, if possible, is the principle mode of surgical treatment. Surgical procedures to increase the surface area of the small intestine or improve its function may be of benefit in experienced hands, particularly in the paediatric population. Intestinal transplant is indicated at present for patients who have failed to tolerate long-term parenteral nutrition but with increasing experience, there may be a potentially expanded role for its use in the future.

    Stercoral perforation of the colon due to fecaloma is a rare disease and less than 100 cases have been described in the literature. The disease mainly involves the rectosigmoid colon. The condition is correlated with longstanding decubitus, chronic constipation, abuse of laxatives and/or constipating agents (anticholinergics, neuroleptics, etc). We report a case of 82-year old woman who presented a covered colonic perforation due to fecaloma, related with a history of longstanding decubitus because of senile dementia, chronic constipation and use of anticholinergic drugs.

    The palmar triangle is an area vascularized by perforator arteries arising from the common digital palmar arteries. The aim of this article was to perform an anatomical study of common digital palmar arteries perforators. Twelve injected specimens were included in this study. The purpose was to quantify the number of perforator arteries of each common digital palmar arteries in the 2nd, 3rd, and 4th intermetacarpal space, measure distances between them, between the distal perforator and corresponding commissure, and the distance between the proximal perforator and the superficial palmar arch. Four to eight perforators were arising from common digital palmar arteries of the 2nd, 3rd, and 4th intermetacarpal space. The average distance between perforator arteries was 6.5 mm, between superficial palmar arch and proximal perforator artery - 8.2 mm, between the distal perforator artery and corresponding commissure - 6.3 mm.

    Coronary perforation is a rare complication of percutaneous coronary intervention. We present two different types of coronary intervention, but both ending with coronary perforation. However, these perforations were tackled successfully by covered stents. This article reviews the incidence, causes, presentation, and management of coronary perforation in the present era of aggressive interventional cardiology. Coronary perforations are classified as type I (extraluminal crater), II (myocardial or pericardial blushing), and III (contrast streaming or cavity spilling). Types I and II coronary perforations are caused by stiff or hydrophilic guidewires. Type I has a benign prognosis, whereas type II coronary perforations have the potential to progress to tamponade. Type III coronary perforations are caused by balloons, stents, or other intracoronary devices and commonly lead to cardiac tamponade necessitating pericardial drainage. However, type III perforations can be managed with covered stents without need for surgical intervention.

    A 23-year-old male underwent a left internal jugular vein catheterization during extended surgery for treatment of multiple fractures due to a traffic accident. Although the catheterization was performed under ultrasound (US) guidance, iatrogenic perforation of the central vein and pleura occurred. The catheter was removed, and the perforated site was addressed under thoracoscopy rather than an open thoracotomy. This case suggests that using US does not completely guarantee a complication-free outcome, and that catheter placement should be carefully confirmed. In addition, this case suggests that thoracoscopy may be an ideal method of resolving a perforation of the central vein and pleura. PMID:24851167

    2015-01-01

    The study of the small bowel (SB) has always been challenging both for clinicians and radiologist. It is a long and tortuous tube that can be affected by various pathologies whose signs and symptoms are usually non specific and can mimic other acute abdominal disorders. For these reasons, imaging plays a central role in the diagnosis of the different pathological conditions that can occur. They are important also in the management and follow up of chronic diseases. We expose and evaluate all the radiological methods that are now available for the study of the SB with particular emphasis on the technological improvement of cross-sectional imaging, such as computed tomography (CT) and magnetic resonance imaging (MRI). These techniques have, infact, highly improved in terms of execution times (fast acquisitions images), patients discomfort and radiation dose, for CT, with consequent reduced biological risks. Moreover, the new post-processing options with multiplanar reconstruction and isotropic images have made significant changes in the evaluation of the exams. Especially MRI scans have been improved by the advent of new sequences, such as diffusion weighted imaging and cine-MRI, parallel imaging and breath-hold sequences and can provide excellent soft-tissue contrast without the use of ionizing radiations.

    AIM To determine if prophylactic clipping of post-polypectomy endoscopic mucosal resection (EMR) mucosal defects of large, flat, right sided polyps prevents perforations. METHODS IRB approved review of all colonoscopies, and prospective data collection of grasp and snare EMR performed by 2 endoscopists between January 1, 2010 and March 31, 2014 in a community ambulatory endoscopy center. The study consisted of two phases. In the first phase, all right-sided, flat polyps greater than or equal to 1.2 cm in size were removed using the grasp and snare technique. Clipping was done at the discretion of the endoscopist. In the second phase, all mucosal defects were closed using resolution clips. Phase 2 of the study was powered to detect a statistically significant difference in perforation rate with 148 EMRs, if less than or equal to 2 perforations occurred. RESULTS In phase 1 of the study, 2121 colonoscopies were performed. Seventy-five patients had 95 large polyps removed. There were 4 perforations in 95 polypectomies (4.2%). The perforations occurred in polyps ranging in size from 1.5 cm to 2.5 cm. In phase 2, there were 2464 colonoscopies performed. One hundred and sixteen patients had 151 large polyps removed, and all mucosal defects were clipped. There were no perforations (P = 0.0016). There were no post-polypectomy hemorrhages in either phase. An average of 2.15 clips were required to close the mucosal defects. The median time to perform the polypectomy and clipping was 13 min, and the median procedure duration was 40 min. Five percent of all patients undergoing colonoscopy in our community based, ambulatory endoscopy center had flat, right sided polyps greater than or equal to 1.2 cm in size. CONCLUSION Prophylactic clipping of the mucosal resection defect of large, right-sided, flat polyps reduces the incidence of perforation. PMID:28360975

    This paper discusses the various methods used to diagnose uterine perforation caused by an IUD. Radiography, or plain film, has a limited use in the diagnosis of uterine perforation since its usefulness depends on the radiopacity of the particular IUD; if the IUD appears on film, plain film does not allow one to conclude whether the device is in its proper position. Several modifications of plain film have been tried but all methods fall short of their goals. Hysterography permits the best diagnostic assessment since it allows the visualization of the entire uterine cavity so that the position of the IUD is immediately evident in cases of embedding and of perforation. Pelvic pneumography can differentiate between intraperitoneal or extraperitoneal locations of perforated IUDs; it can be enhanced by hysterosalpingography and can be done on an ambulatory basis. Ultrasonography simply determines the presence or absence of an IUD, but has the advantage of accurately demonstrating a concomitant pregnancy; the sonogram is not reliable if the IUD is surrounded by omentum or by loops of bowel; ultrasonography can be advantageously coupled with hysterography. Laparoscopy is still the method most used to diagnose uterine IUD perforation; when removal of the device is advisable laparotomy is usually carried out concomitantly; successful laparoscopy requires a skilled and experienced operator. Hysteroscopy is a new and extremely valuable technique which should not be chosen as a primary procedure because it carries a risk of complications. The best prevention of uterine perforation is a meticulous and well executed insertion technique, done only by an experienced operator and after a careful pelvic examination. Uterine size, consistency and position must be exactly known; IUD insertion is easier during or immediately after menstruation. Perforated IUDs should be removed even if considered innocuous, although this is a matter still debated by the specialists. Spontaneous IUD

We report a case of a 24-year-old female patient who presented in emergency with an acute peritonitis due to a gastric perforation on bezoars. Gastrotomy, extraction of bezoars, gastric stitching and peritoneal lavage were performed. Post operative period was uneventful. A new careful interrogation into the patient's previous habits found glue-eating custom during the four last years.

    Perforation of Meckel's diverticulum with enteroliths is a rare complication. Here, we report a case of perforation of Meckel's diverticulum with enteroliths, which could be accurately diagnosed by the preoperative computed tomography (CT). A 46-year-old man with acute onset of severe abdominal pain, and a localized muscle guarding in the right hypochondrium, had a solitary stone detected in the right abdomen by the radiography. The abdominal CT revealed a saclike outpouching of the small intestine, containing air/fluid levels and an enterolith, with surrounding free air and mesenteric inflammatory change in the right paraumbilical area. He was diagnosed as the perforation of Meckel's diverticulum with enterolith, and the emergency operation was indicated. The perforated Meckel's diverticulum was identified approximately 90 cm proximal to the ileocecal valve. The diverticulum was transected at the base, and removed. The patient's postoperative course was uneventful. This case strongly suggested the ability of CT enterography to accurately diagnose pathologies involving the small intestine, such as the perforation of Meckel's diverticulum, which open premises for its use in the diagnosis of acute abdomen preoperatively.

    During video capsule endoscopy (VCE), several factors, such as air bubbles, food material in the small bowel, and delayed gastric and small bowel transit time, influence diagnostic yield, small bowel visualization quality, and cecal completion rate. Therefore, bowel preparation before VCE is as essential as bowel preparation before colonoscopy. To date, there have been many comparative studies, consensus, and guidelines regarding different kinds of bowel cleansing agents in bowel preparation for small bowel VCE. Presently, polyethylene glycol- (PEG-) based regimens are given primary recommendation. Sodium picosulphate-based regimens are secondarily recommended, as their cleansing efficacy is less than that of PEG-based regimens. Sodium phosphate as well as complementary simethicone and prokinetics use are considered. In this paper, we reviewed previous studies regarding bowel preparation for small bowel VCE and suggested optimal bowel preparation of VCE. PMID:26880894

    Peritonitis due to gastroduodenal ulcer perforation disease is a rare entity in pediatric surgery. In Senegal, no study has been dedicated to ulcer complications in children. The aim of this study was to describe the epidemiology, diagnosis, and treatment of perforated peptic ulcer in patients less than 15 years old. This retrospective study was conducted in the Surgical Emergencies and Paediatric Surgery Department at Aristide Le Dantec University Hospital Center in Dakar, Senegal, during a period of 11 years (January 1999 to December 2010). We found 4 children who presented perforated gastroduodenal ulcer: 3 females and 1 male. The average age of these patients was 9 years (range, 7-14 years). No family history was found. We noted 3 cases of perforated duodenal ulcer and one perforated gastric ulcer. The clinical diagnosis was suspected based on a peritoneal irritation syndrome. A plain x-ray of the abdomen was taken in all patients, which objectified a pneumoperitoneum image in 3 cases. The leukocytosis was constant. Treatment in all patients consisted on pre-, intra-, and postoperative intensive care, supra- and infraumbilical midline laparotomy, which allowed us to perform a debridement-suture of the gap followed by epiploplasty and extensive washing with lukewarm physiologic serum. Adjuvant therapy based on anti-ulcer and antibiotic therapy was initiated. Bacteriological examination of peritoneal fluid isolated a polymicrobial flora. Helicobacter pylori was not isolated. Histological examination of the biopsied perforation edges showed a benign ulcer in all cases. The follow-up endoscopy was performed 4 weeks after surgery and showed cicatrization of the ulcer in all patients. After a mean of 2 years, no recurrence was noted. The gastric or duodenal ulcer in children is rare. It is often discovered at the stage of perforation, a complication for which the essential treatment is surgery. Routine screening would certainly help to reduce the risk of this

    Small bowel obstruction due to undigested fibre from fruits and vegetables is a rare but known medical condition. We report a case of small bowel obstruction caused by a whole cherry tomato in a patient without a past medical history of abdominal surgery. A 66-year-old man presented to the emergency department complaining of lower abdominal pain with nausea and vomiting. His last bowel movement had occurred on the morning of presentation. He underwent abdominal computed tomography (CT), which showed a sudden change of diameter in the distal ileum with complete collapse of the proximal small bowel segment. Laparoscopy confirmed a small bowel obstruction with a transition point close to the ileocaecal valve. An enterotomy was performed and a completely undigested cherry tomato was retrieved. To our knowledge, this is the first reported case of a small bowel obstruction caused by a whole cherry tomato.

    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.

    A perforated peptic ulcer in a child is a rare entity. Severe abdominal pain in an ill-appearing child with a rigid abdomen and possibly with signs of shock is the typical presenting feature of this life-threatening complication of peptic ulcer disease. We present a case of a 14.5-year-old adolescent girl who developed abdominal and shoulder pain that resolved after 1 day. She was then completely well for 2 days until the abdominal and shoulder pain recurred. On examination, she appeared well, but in pain. A chest radiograph revealed a large pneumoperitoneum. She underwent emergent laparoscopic omental patch repair of a perforated ulcer on the anterior wall of her stomach. Result of a urea breath test to detect Helicobacter pylori was negative. The differential diagnosis of pneumoperitoneum in children is discussed, as are childhood perforated peptic ulcer in general, and the unique clinical features present in this case in particular.

    The forefoot is critical to normal walking; thus, any reconstruction of forefoot defects, including the soft tissues, must be carefully done. The free perforator flap, with its physiologic circulation, lower donor site morbidity, and minimal thickness is the most popular technique in plastic and microsurgery, and is theoretically the most suitable for such forefoot reconstruction. However, these flaps are generally recognized as more difficult and time-consuming to create than other flaps. In 41 patients with traumatic forefoot defects, we reconstructed the forefoot integument using 5 types of free perforator flaps. The overall functional and cosmetic outcomes were excellent. Three flaps required repeat exploration; one survived. The most common complications were insufficient perfusion and the need for second debulking. The key to our success was thoroughly debriding devitalized bone and soft tissue before attaching the flap. Forefoot reconstruction with a free perforator flap provides better function, better cosmesis, better weightbearing, and better gait than the other flaps we have used.

    Prenatal ultrasound has led to confidence in the antenatal diagnosis of intestinal obstruction allowing counseling and birth planning. We describe a male infant of a diabetic mother who had an antenatal diagnosis of distal bowel obstruction. This baby was subsequently found not to have bowel obstruction, but a congenital enteropathy - microvillous inclusion disease. The antenatal scans had demonstrated polyhydramnios as well as multiple fluid-filled dilated loops of bowel in the fetal abdomen. To our knowledge, similar prenatal ultrasound findings have not been previously described in this condition. The baby was delivered in a pediatric surgical center and postnatally there was no evidence of bowel obstruction either clinically or on abdominal X-ray. This baby initially fed well, but became collapsed and acidotic on his third day, having lost 26% of his birth weight due to excessive stool loss. The diagnosis of microvillous inclusion disease was made by electron microscopy of a small bowel biopsy. Congenital microvillous inclusion disease is a very rare inherited enteropathy with high mortality and morbidity. This condition, and other enteropathies, should be considered in cases in which antenatally diagnosed bowel obstruction is not confirmed after birth.

    Gender-related physiological variations in gastrointestinal (GI) symptomatology have been observed in women of reproductive age. Many women experience cyclical changes in GI symptomatology during their menstrual cycle, particularly alteration in their bowel habits. Physiological studies of healthy women during the menstrual cycle showed a prolonged GI transit time during the luteal phase, either in the oro-cecum route or in the colon. Worsened GI symptoms, such as abdominal pain, bloating or diarrhea are observed in patients with irritable bowel syndrome (IBS) during menses. This may be due to elevated prostaglandin levels during menses, with an enhanced perception of viscera-somatic stimuli resulting in nausea, abdominal distension and pain. Also patients with IBS or IBD demonstrate a cyclical pattern more closely related to their bowel habits than healthy controls. Women with inflammatory bowel disease (IBD) also have exacerbated symptoms during menses; however, it is unclear whether this relates to physiological variation or disease exacerbation in IBS or IBD. Studies examining the association of the menstrual cycle and GI symptomatology in patients with IBS or IBD, have not yet clarified the underlying mechanisms. Moreover medications—such as non-steroidal anti-inflammatory drugs and oral contraceptive pills used for dysmenorrhea and menstrual migraine in those patients have not well been controlled for in the previous studies, which can contribute to further bias. Understanding changes in GI symptomatology during the menstrual cycle may help to determine the true extent of disease exacerbation and proper management strategy. PMID:25788484

    2004-01-01

    Irritable bowel syndrome (IBS) is one of the most common 'functional' gastrointestinal disorders accounting for 3% of all primary care consultations, with a strong female predominance. Although most of the literature comes from Western industrialized societies, when it has been looked for, this disorder appears to be equally common in the Third World. It is characterized by chronic abdominal pain or discomfort associated with disordered bowel habit and visceral hypersensitivity. Anxiety and somatization are more common in IBS than in the general population and may encourage consultation; however, they correlate poorly with symptoms. Bacterial gastroenteritis may be followed by the development of IBS in 5-10% of patients, depending on the severity of initial illness and prior anxiety or depression. The Rome criteria allow reliable diagnosis provided that there are no 'alarm' features which mandate further investigation. Microscopic colitis and bile salt malabsorption can easily be mistaken for IBS, as can chronic infestations or infections which should be considered, while recognizing that these are extremely uncommon in westernized societies. Some patients respond to exclusion diets as lactose and wheat intolerance are common. Others with prominent anxiety and/or depression respond to psychotherapy or antidepressants. Diarrhoeal symptoms respond to loperamide and 5HT3 receptor antagonists, while constipation responds to 5HT4 agonists. Antispasmodics may have limited benefit in treating pain. Low-dose tricyclic antidepressants are also helpful in alleviating pain and anxiety, even in those without obvious psychiatric disorders. If diagnostic criteria are met, then once diagnosed, new diagnoses rarely appear.

    Irritable bowel syndrome (IBS) is a functional gastrointestinal disease with a high population prevalence. The disorder can be debilitating in some patients, whereas others may have mild or moderate symptoms. The most important single risk factors are female sex, younger age and preceding gastrointestinal infections. Clinical symptoms of IBS include abdominal pain or discomfort, stool irregularities and bloating, as well as other somatic, visceral and psychiatric comorbidities. Currently, the diagnosis of IBS is based on symptoms and the exclusion of other organic diseases, and therapy includes drug treatment of the predominant symptoms, nutrition and psychotherapy. Although the underlying pathogenesis is far from understood, aetiological factors include increased epithelial hyperpermeability, dysbiosis, inflammation, visceral hypersensitivity, epigenetics and genetics, and altered brain–gut interactions. IBS considerably affects quality of life and imposes a profound burden on patients, physicians and the health-care system. The past decade has seen remarkable progress in our understanding of functional bowel disorders such as IBS that will be summarized in this Primer. PMID:27159638

    In corneal perforations associated with extensive progressive corneal disease, a technique using tissue adhesive closure of the perforation site and reformation of the anterior chamber before penetrating keratoplasty or conjunctival flap mobilization has been described. Over the past year, six eyes have been successfully treated in this manner. This method allows reformation of the eye under local anesthesia as an emergency procedure without incarceration or injury of the intraocular contents and without pain to the patient. The definitive surgical procedure can then be performed safely under retrobulbar anesthesia.

    Pyometra, by definition, is a collection of purulent fluid within the uterine cavity. Incidence has been estimated to range from 0.1% to 0.5%. Typically, this is linked to postmenopausal women; however, it has been linked to premenopausal women with concordant use of intrauterine devices. Based on our knowledge, there have been less than 50 recorded cases reported in the English literature regarding perforation of pyometra resulting in acute abdomen and fewer than 25 resulting in pneumoperitoneum. We report a patient who was evaluated for diffuse peritonitis caused by perforated pyometra who was successfully treated with surgical intervention. PMID:28357145

    The development of laser skin perforator device for obtaining blood samples is presented. The use of photoelectric proximity photoelectric sensor permits to determine the focal point eliminating any contact and them avoiding the risk of contamination. Perforation of about 0.2 mm - 0.5 mm in diameter can be obtained in order to take the sample of blood. The method permits to make the blood analysis not only avoiding the contamination risk but also diminishing the pain sensation in comparison with metal lancet.

    Scrub typhus is an acute febrile illness usually presenting with fever, myalgia, headache, and a pathognomonic eschar. Severe infection may lead to multiple organ failure and death. Gastrointestinal tract involvement in the form of gastric mucosal erosions and ulcerations owing to vasculitis resulting in gastrointestinal bleeding is common. This process may worsen a pre-existent asymptomatic peptic ulcer, causing duodenal perforation, and present as an acute abdomen requiring surgical exploration. We report the case of a patient with no previous symptoms or risk factors for a duodenal ulcer, who presented with an acute duodenal perforation, probably precipitated by scrub typhus infection.

    Clinical presentation at diagnosis and disease course of both Crohn's disease (CD) and ulcerative colitis are heterogeneous and variable over time. Since most patients have a relapsing course and most CD patients develop complications (e.g. stricture and/or perforation), much emphasis has been placed in the recent years on the determination of important predictive factors. The identification of these factors may eventually lead to a more personalized, tailored therapy. In this TOPIC HIGHLIGHT series, we provide an update on the available literature regarding important clinical, endoscopic, fecal, serological/routine laboratory and genetic factors. Our aim is to assist clinicians in the everyday practical decision-making when choosing the treatment strategy for their patients suffering from inflammatory bowel diseases.

    Although common side effects of regorafenib include hand-and-foot syndrome and diarrhoea, the incidence of gastrointestinal perforation is reportedly unknown. We describe our experience with the case of a 65-year-old woman treated with regorafenib as a third-line therapy for progressive caecal cancer with multiple hepatic metastases after 4 and 6 courses of systemic mFOLFOX6 + bevacizumab (BV) and FOLFIRI + BV chemotherapy, respectively. The patient used regorafenib for 32 days but visited our hospital with abdominal pain during the second course. She was diagnosed with acute appendicitis and treated conservatively with antibiotics. The abdominal findings did not improve, and a computed tomography evaluation on day 4 of hospitalization revealed free air lateral to the caecal tumour, liver surface, and epigastric region. The patient underwent same-day emergency surgery based on a diagnosis of gastrointestinal perforation with generalized peritonitis. Upon observing digestive fluid leakage into the peri-ileocaecal area and a 5-mm perforation in the appendix, the patient was diagnosed with peritonitis due to gastrointestinal perforation. Ileocaecal resection with D2 debridement was performed, and a colostomy was opened into the ileum and ascending colon. We conclude that our patient developed gastrointestinal perforation during regorafenib therapy and note that clinicians should be aware of this possible complication in patients with a history of prior treatment with BV.

    Introduction Spontaneous perforation of the oesophagus is diagnosed late in over 50% of cases. Misdiagnosis may be due to atypical presentations. Primary repair is technically demanding in this setting and the risk of failure is high. Presentation of case An 85 year-old lady presented with an atypical cohort of mild nonspecific symptoms in spite of a pleuro-mediastinal purulent collection secondary to an undiagnosed spontaneous perforation of the oesophagus occurred seven days before. Despite the extent of perforation (3 cm in length), the late diagnosis and the necrosis of the muscular wall, the oesophagus was successfully repaired by means of a stapler. Discussion The mechanism of the atypical presentation is discussed and possible modalities of treatment of delayed oesophageal perforations are reviewed, with particular reference to primary repair and to the possible use of staplers within this setting. Conclusion Even large spontaneous perforations of the oesophagus can result in a contained abscess, with no frank sepsis. Diagnosis can be missed for days in these cases. The attempt at primary repair of the oesophagus is still indicated. The use of a stapler is preferable in such cases as a perfect mucosal approximation is provided with minimal manipulation and with the use of inert, well tolerated material, which does not tend to become infected.

    A 5-year-old female Poodle was presented with a 3-month history of recurrent abscess and fistula formation on the right abdominal wall. Radiographic and ultrasonographic examinations demonstrated an enterocutaneous fistula formation secondary to foreign body perforation of the colon. Additionally, the diagnosis of a pyometra was made. Twenty-four hours after surgical therapy (ventral midline coeliotomy, foreign body removal, closure of the colon perforation, abdominal lavage and drainage, revision of the fistula) the patient was euthanized due to sepsis and incipient multiorgan dysfunction.

    We report the successful conservative management of an unusual case of esophageal perforation associated with an upper thoracic spinal fracture from blunt trauma in Minamata, Kumamoto, Japan. A 69-year-old man became paraplegic secondary to an L1 burst fracture caused by a boating accident and underwent posterior fixation on the day of admission. The patient also had a minimally displaced T4 vertebral fracture. Fever, dyspnea and elevated inflammatory markers all persisted postoperatively. Computed tomography showed free mediastinal air at the T4 level, and an esophagram showed contrast medium leakage, which helped diagnose esophageal perforation. The esophageal perforation healed with conservative treatment without life-threatening complications. The possibility of esophageal injury should always be considered when treating upper thoracic spinal injuries due to blunt trauma. PMID:28053736

    Endoscopic treatment for superficial non-ampullary duodenal tumors is technically difficult and challenging due to the anatomical characteristics of the duodenum. It is frequently complicated by procedural accidents, such as perforation. Surgical repair has long been the standard treatment for acute iatrogenic gastrointestinal perforation. However, endoscopic closure has recently emerged as an attractive alternative. In the patient presented herein, the over-the-scope-clipping system (OTSC system) was found to be useful for closing a duodenal perforation that had occurred during endoscopic submucosal dissection. For endoscopists who perform endoscopic treatment of the duodenum, endoscopic closure with the OTSC system is considered to be a technique that is necessary to master. PMID:27803406

    Posttransplantation lymphoproliferative disorder (PTLD) is a relatively rare and life-threatening complication after organ transplantation. From 1999 to 2012, 45 adult patients underwent heart transplantation at our hospital. Two of the patients developed PTLD after transplantation and required emergency surgery due to intestinal perforation. These cases were informative regarding the adequate surgical management of such cases. Both cases revealed Epstein-Barr virus-related PTLD. The optimal treatment of PTLD remains controversial, and PTLD with gastrointestinal perforation could be critical because the patients are already debilitated and immunocompromised after transplantation. Therefore, the nonspecific abdominal symptoms can be diagnostic for PTLD, and proper surgical intervention should be performed immediately. We present these two suggestive and rare cases in regard to the management of perforation with PTLD and a review of literature. PMID:25692442

    Adhesive small bowel obstruction is a frequent cause of hospital admission. Water soluble contrast studies may have diagnostic and therapeutic value and avoid challenging demanding surgical operations, but if bowel ischemia is suspected, prompt surgical intervention is mandatory. A 58-year-old patient was operated for extensive adhesive small bowel obstruction after having had two previous laparotomies for colorectal surgery, and had a complex clinical course with multiple operations and several complications. Different strategies of management have been adopted, including non-operative management with the use of hyperosmolar water soluble contrast medium, multiple surgical procedures, total parenteral nutrition (TPN) support, and finally use of antiadherences icodextrin solution. After 2 years follow-up the patient was doing well without presenting recurrent episodes of adhesive small bowel obstruction. For patients admitted several times for adhesive small bowel obstruction, the relative risk of recurring obstruction increases in relation to the number of prior episodes. Several strategies for non-operative conservative management of adhesive small bowel obstruction have already addressed diagnostic and therapeutic value of hyperosmolar water soluble contrast. According to the most recent evidence-based guidelines, open surgery is the preferred method for surgical treatment of strangulating adhesive small bowel obstruction as well as after failed conservative management. Research interest and clinical evidence are increasing in adhesions prevention. Hyaluronic acid-carboxycellulose membrane and icodextrin may reduce incidence of adhesions.

    A seven-month-old infant was admitted to our hospital with a 1-wk history of shortness of breath, dysphagia, and fever. Diagnosis of esophageal perforation following fish vertebra ingestion was made by history review, pneumomediastinum and an irregular hyperdense lesion noted in initial chest radiogram. Neck computed tomo-graphy (CT) confirmed that the foreign body located at the cricopharyngeal level and a small esophageal tracheal fistula was shown by esophagogram. The initial response to treatment of fish bone removal guided by panendoscopy and antibiotics administration was poor since pneumothorax plus empyema developed. Fortunately, the patient’s condition finally improved after decortication, mediastinotomy and perforated esophagus repair. To our knowledge, this is the first case report of esophageal perforation due to fish bone ingestion in infancy. In addition to particular caution that has to be taken when feeding the innocent, young victim, it may indicate the importance of surgical intervention for complicated esophageal perforation in infancy.

    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.

    Rectangular specimens of Twaron{reg_sign} fabric, clamped on two opposite sides, are subjected to impact perforation by 9.5 mm diameter spherical steel projectiles at speeds ranging from 140 m/s to 420 m/s. This plain woven fabric, comprising PPTA (poly-paraphenylene terepthalamide) fibers, is commonly employed in flexible an-nor applications. Its perforation response is examined in terms of residual velocity, energy absorbed and resulting deformation patterns. The existence of a critical or transition impact velocity, beyond which there is a significant reduction in energy absorbed by perforation, is observed. Differences in creasing and deformation induced in specimens are also demarcated by this transition impact velocity. Effects of difference in boundary conditions (clamped and free) on yarn breakage are also noted. A numerical model, based on an initially orthogonal network of pin-jointed bars interconnected at nodes, is formulated to simulate the fabric. Fiber yam mechanical properties are represented via a three-element spring-dashpot model which encapsulates viscoelastic behavior and fiber failure. Numerical results exhibit good correlation with experimental observations in terms of prediction of threshold perforation velocity, energy absorbed, occurrence of a transition critical velocity and fabric deformation characteristics.

    1995-10-01

    The productivity characteristics of perforated gas well are investigated for the first time under real conditions considering drilling damage, perforation compacted zone and anisotropy in this paper. A non-linear finite element model for non-Darcy flow in perforated gas reservoir is built to consider the effects of twelve factors on productivity ratio (PR) of perforated gas well. The nomographs for two cases are presented in this paper. Compared with previous works, the following results are found: (1) the effects of drilling damage and perforation diameter on PR of gas well are more remarkable than that in oil well; (2) any perforation phase may be the best or the worst as to perforating gas well, which depends on anisotropy, drawdown and that whether or not perforations are beyond drilling damage zone; (3) the increase in perforation length hardly improve PR of gas well when perforations have been beyond drilling damage zone. The new method is suggested to predict or determine the turbulent flow co-efficient D{prime}, total skin S, pseudo skin St{prime}, and individual skin factors (Sp, Sd, Sdp) in perforated gas well. The minimum underbalance required to obtain a zero perforating skin is discussed as well. Some drawbacks of the equation proposed by Tariq (SPE 20636) are analyzed and a new Reynold`s number criterion is established. The critical Reynold`s number for clean perforation is dependent on formation permeability. Based on this research, the principle and the program for optional design of perforating completion in gas well are highlighted. These new concepts, results and conclusions would be of importance to both gas well perforating and gas reservoir engineering.

    Inflammatory bowel disease (IBD) is the term used for a group of diseases with yet unknown etiology, prevalence of which is increasing almost everywhere in the world. The disease was almost non-existent four decades ago in the east, including the middle-east, while now a days it is seen more and more. In addition to the increasing prevalence, our knowledge about its pathogenesis, clinical course, diagnosis, and treatment has changed dramatically over the past couple of decades. This has changed our concept of this group of diseases, their diagnosis, treatment, and treatment goals. Considering the vast literature on the subject, it is timely to review major topics in IBD with a look on the regional progress and knowledge as well. This essay is aimed to cover this task.

    Purpose: To assess the rate of severe bowel complications during treatment with the antivascular endothelial growth factor monoclonal antibody bevacizumab. Methods and Materials: We performed a retrospective evaluation of bevacizumab-associated severe intestinal adverse events from our institutional database. Results: A total of 33 patients started treatment with bevacizumab at our institution during the first 6 months after its approval in Germany. Three patients (9%) presented with severe bowel complications: two with acute ischemic colitis and one with gastrointestinal perforation with a fatal outcome. All 3 patients had undergone radiotherapy directed to the pelvis before treatment with bevacizumab. None of the 30 patients without bowel complications had been pretreated with infradiaphragmatic irradiation. Histologic evaluation of bowel biopsies and resection specimens revealed severe ischemic bowel damage as the pathophysiologic background of the clinical findings. Conclusion: This report contributes to the pathophysiologic clarification of bevacizumab-induced bowel complications and points to a potentially increased risk of severe ischemic damage during treatment with bevacizumab in patients who have undergone previous radiotherapy.

  11. Biomarkers of Irritable Bowel Syndrome

    Kim, Jae Hak; Lin, Eugenia; Pimentel, Mark

    2017-01-01

    Traditionally, irritable bowel syndrome (IBS) has not been regarded as an organic disease, and the pathophysiology of IBS is heterogeneous. Currently, the diagnosis of IBS is based upon the Rome diagnostic criteria. The performance of these criteria is only modest in predicting IBS, and moreover their validation is lacking. Additionally, as functional symptoms are common in the general population, healthy controls or volunteers are difficult to define and there is currently no definition of “normal” in the Rome criteria. Due to the weaknesses of the current diagnostic criteria, patients and doctors expect new gold standard diagnostic tools. Various etiologic mechanisms result in potential biomarkers. The focus of this research has been to find non-invasive biomarkers from serum, breath gas, and fecal materials. Though biomarkers should be based on biological and pathogenic processes, most biomarkers for IBS have been developed to identify organic diseases and therefore eliminate IBS. To date, these types of biomarkers for IBS have been disappointing. The purposes of developing biomarkers include improvement of diagnosis, differentiation from other organic diseases, and discrimination of IBS subtypes. A true mechanistic biomarker would make it possible to rule in IBS, rather than to rule out other organic diseases. New serologic biomarkers for diarrhea-predominant IBS have been introduced based on the pathophysiologic findings from a rat model and validation in a large-scale clinical trial. Further investigations of abnormal organic findings from each subtype of IBS would enable the development of new, simple subtype-specific biomarkers. PMID:27817184

    A combined septal perforation repair and rhinoplasty was performed in 20 patients (12 males, eight females; age range 16-36, mean age 29.6) presenting with septal perforations (size 1-4 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. The perforation was totally closed in 18 cases (90 per cent) with complete resolution of the pre-operative symptoms occurring in 16 (80 per cent). Cosmetically, 19 cases (95 per cent) were very satisfied with their aesthetic result. The exposure provided by the external approach proved to be very helpful in the process of septal perforation repair. Our results show that septal perforation repair could safely be combined with rhinoplasty and that some of the rhinoplasty manoeuvres used could even facilitate the process of septal perforation repair.

    AIM: To investigate the safety and efficacy of endoscopic band ligation (EBL) for bleeding lesions in the small bowel. METHODS: This is a retrospective study evaluating EBL in six consecutive patients (three males, three females, 46-86 years of age) treated between May 2009 and February 2014: duodenal vascular ectasia; 1, jejunal bleeding diverticulum; 1, ileal Dieulafoy’s lesion; 1 and ileal bleeding diverticula; 3. The success of the initial hemostasis was evaluated, and patients were observed for early rebleeding (within 30 d after EBL), and complications such as perforation and abscess formation. Follow-up endoscopies were performed in four patients. RESULTS: Initial hemostasis was successfully achieved with EBL in all six patients. Eversion was not sufficient in four diverticular lesions. Early rebleeding occurred three days after EBL in one ileal diverticulum, and a repeat endoscopy revealed dislodgement of the O-band and ulcer formation at the banded site. This rebleeding was managed conservatively. Late rebleeding occurred in this case (13 and 21 mo after initial EBL), and re-EBL was performed. Follow-up endoscopies revealed scar formation and the disappearance of vascular lesions at the banded site in the case with a duodenal bleeding lesion, and unresolved ileal diverticula in three cases. Surgery or transarterial embolization was not required without any complications during the median follow-up period of 45 (range, 2-83) mo. CONCLUSION: EBL is a safe and effective endoscopic treatment for hemostasis of bleeding lesions in the small bowel. PMID:25324920

    Visceral hypersensitivity is often considered to play a major etiologic role in the pathophysiology of irritable bowel syndrome in adults, and some authors argue that this increased sensitivity is mainly due to psychological factors. In contrast, there are no data in children with irritable bowel syndrome which confirm this relationship. The aim of the study was to evaluate the relationship between psychosocial aspects and sensorymotor function in children affected by irritable bowel syndrome. Ten children fulfilling the Rome II criteria for irritable bowel syndrome and seven healthy controls were enrolled. We studied the thresholds and the perception of visceral stimuli in the rectum by means of an electronic barostat (isobaric phasic distentions, 3 mmHg/1 min, interval 1 min) and a validated questionnaire. Personality features were evaluated by means of the Big Five Questionnaire for Children. Sleep, mood disturbance, anxiety and individual performance (missed school days, school results and social activities) were also evaluated. Children with irritable bowel syndrome showed significantly lower thresholds for discomfort (14.8 +/- 3.5 vs 22.3 +/- 6.9 mmHg, P = 0.010) and a higher cumulative perception score (28.2 +/- 11.1 vs 12.3 +/- 8.0, P = 0.005) compared with healthy controls. A higher emotional instability (57.8 +/- 7.0 vs 48.7 +/- 10.1, P = 0.047), sleep disturbance (7.2 +/- 1.0 vs 9.3 +/- 0.5, P = 0.004) and anxiety (6.3 +/- 2.0 vs 2.3 +/- 1.7, P = 0.009) were observed in irritable bowel syndrome patients. Moreover, in a multivariate analysis, the cumulative perception score was significantly related to emotional instability (P = 0.042). In conclusion children with irritable bowel syndrome exhibit visceral hypersensitivity and psychosocial impairment. Emotional instability, as a personality feature in these children, seems to modulate the perception response to visceral stimulations.

    Perforated pipes are utilized to divide a fluid flow into several smaller streams. Uniform flow distribution requirement is of great concern in engineering applications because it has significant influence on the performance of fluidic devices. For industrial applications, it is crucial to provide a uniform velocity distribution through orifices. In this research, flow distribution patterns of a closed-end multiple outlet pipe standing vertically for air delivery in the horizontal direction was simulated. Computational Fluid Dynamics (CFD), a tool of research for enhancing and understanding design was used as the simulator and the drawing software SolidWorks was used for geometry setup. The main purpose of this work is to establish the influence of size of orifices, intervals between outlets, and the length of tube in order to attain uniformity of exit flows through a multi outlet perforated tube. However, due to the gravitational effect, the compactness of paddy increases gradually from top to bottom of dryer, uniform flow pattern was aimed for top orifices and larger flow for bottom orifices.

    A patient with a history of schizophrenia was admitted to our hospital in an already severe stage of necrotizing fasciitis of the neck, complicated with mediastinitis and gangrene. Later on, he also developed a vena cava superior syndrome and sepsis. In the few cases and small series described in the literature, necrotizing fasciitis of the neck is usually associated with surgery or trauma. Less frequently, an orodental or pharyngeal infection, often innocuous, is the underlying cause. None of these causes could be identified in our patient. Initially, on computer-assisted tomography (CT) scan, a tracheal rupture was suspected, but this diagnosis could not be confirmed on bronchoscopic examination. On gastroscopy, a stenotic oesophageal segment was discovered. Biopsy of this segment showed a poorly differentiated squamous cell carcinoma. The patient died in sepsis. Autopsy confirmed the presence of a large proximal oesophageal tumour with perforation. As far as we know, no case of a necrotizing fasciitis of the neck caused by perforation of a formerly unknown oesophageal carcinoma has been reported. Even mediastinitis, with or without gangrene, is rarely associated with oesophageal cancer, and in the few cases reported it is always due to fistulization after surgery.

    Increasing reports on the incidental ingestion of metallic bristles from barbeque grill cleaning brushes have been reported. We sought to describe the clinical presentation and grilling habits of patients presenting after ingesting metallic bristles in an attempt to identify risk factors. We performed a chart review of six patients with documented enteric injury from metallic bristles. Subjects were contacted and administered a survey focused on the events surrounding the bristle ingestion. We arranged for in-home visits to inspect the grill and grill brush whenever possible. Of the six subjects identified, three (50%) were male, five (83%) were white, and they ranged in age from 18 to 65 years (mean 42.5). All complained of abdominal pain. All bristles were identified by CT scan. Three patients underwent laparoscopic enterorrhaphy, and two underwent laparotomy. The remaining patients did not require intervention. None had replaced their grill brush in at least two years. Surgeon's awareness of this unusual injury is important to identify and manage this problem. Alternative methods to clean the grill should be sought and grill brushes should be replaced at least every two years.

    Perforating technology has undergone significant advances during the last decade. Tubing-conveyed perforating, underbalanced perforating, high-shot-density guns, better shaped charges, and improved gun systems have contributed to safer operations and improved productivity of the perforated completions. A recent development described in this paper is a perforating tool that makes real-time downhole measurements (including pressure, flow rate, temperature, gamma ray, casing-collar locator (CCL), and cable tension) during a perforating run and can selectively fire a number of guns at different depths or times. In addition to providing better control of the perforating process, the simultaneous downhole measurements can provide in a single trip a production log, conventional well tests before and after perforating, and a fill-up or slug test soon after perforating for underbalanced conditions. Thus, the completion can be evaluated in real time and any needed remedial reperforating can be performed while the gun is still in the hole. Other applications include limited-entry perforating, monitoring of bottomhole pressure (BHP) during minifracture jobs, better depth control with a gamma ray detector, fluid-level monitoring, and underbalance control. The applications of these measurements, with field data obtained with the Measurement While Perforating (MWP{sup SM}) tool, are the subject of this paper. Examples show the capabilities and the versatility of the MWP tool.

    An 86 year old male with a four-day history of nonspecific gastrointestinal symptoms was found on colonoscopy to have evidence of sigmoid colon obstruction and possible perforation. Emergent operative exploration revealed diffuse peritonitis, sigmoid perforation, adjacent dense adhesions, and a foreign body protruding through the perforated area. Pathologic examination showed the foreign body to be a sliver of bone consistent with chicken bone and the sigmoid subacute perforation to be associated distally with a circumferential ulcerated obstructing mass, microscopically seen to be transmurally infiltrating adenocarcinoma, signet-ring cell type. There was extensive acute and organizing peritonitis, 100% Escherichia coli was cultured from peritoneal fluid, and the patient died two days postoperatively with sepsis and hypotension. This appears to be the fifth reported case of colonic perforation resulting from foreign body perforation due to previously undiagnosed adenocarcinoma. The four previously reported cases were all deeply invasive adenocarcinoma of sigmoid colon, and the foreign bodies included three chicken/poultry bones and a metallic staple. These five cases are highly unusual examples of a potentially lethal malignant neoplasm being clinically revealed by a usually (but not always) innocuous event, the ingestion of a small foreign body.

    Ingestion of foreign bodies is common in clinical practice. Most ingested foreign bodies will pass through the gastrointestinal (GI) tract without any problems. While GI tract injury due to the ingested foreign body such as a toothpick, a fishbone, a date pit, or a chicken bone, is common, duodenal perforation is rare. In this report, our experience with this rare entity is shared. We present a 38-year-old male patient with GI tract perforation in the bulbus of the duodenum due to a leg of glasses. The patient was admitted to our hospital with severe abdominal pain. Right upper quadrant tenderness was detected at physical examination, and leukocytosis on the laboratory test results. Plain X-ray and computerized tomography showed an ingested foreign body in the bulbus of the duodenum. A leg of glasses perforating the duodenum was removed with endoscopy. The patient was managed nonoperatively, and discharged without any complications on the eighth day after endoscopy. Endoscopic removal and nonoperative management may be feasible in carefully selected patients with duodenal-perforating foreign bodies. PMID:27920661

    Accurate serological assays are desirable for the diagnosis of inflammatory bowel disease. Among several serological markers anti-Saccharomyces cerevisiae mannan antibodies and perinuclear antineutrophil cytoplasmic autoantibodies are highly disease specific for Crohn's disease and ulcerative colitis, respectively. Combining the two improves their specificity. Sensitivity, however, is still low. Due to lack of standardization and vast interobserver variability, they cannot be used as the only diagnostic criteria but can assist clinicians in diagnosing and categorizing patients with inflammatory bowel disease as well as in helping them to take therapeutic decisions.

    A 34-year-old male patient who had undergone total colectomy and J-pouch ileanal anastomosis subsequent to diagnosis of familial adenomatous polyposis five years previously was admitted to the emergency room with complaints of severe abdominal pain of a four-day duration. Physical examination revealed widespread tenderness throughout the abdomen, especially in the lower quadrant. Abdominal ultrasonography revealed fluid between intestinal loops and computed tomography revealed free air and fluid in the abdomen. During laparotomy to expand the ileal J-pouch to approximately 12 cm in diameter, a 2-mm perforation was detected in the blind end of the ileal J-pouch. The perforation was repaired primarily and protective ileostomy was performed. During postoperative endoscopy, neither obstruction nor stasis was observed, but pouchitis was observed in the ileal J-pouch. The patient was postoperatively discharged on the 20th day and followed endoscopically. The endoscopic findings were normal in the sixth month postsurgery.

Computed tomography revealed pneumoperitoneum and free fluid in keeping with visceral perforation. In addition, a large hair bolus was seen extending in contiguity from the stomach to the jejunum. A laparotomy was performed, revealing an anterior gastric perforation secondary to a 120cm long trichobezoar, which had formed a cast of the entire stomach, duodenum and proximal jejunum. The bezoar was removed and an omental patch repair to the anterior ulcer was performed. The patient made an excellent postoperative recovery and was discharged home with psychiatric follow-up review.

    This patent describes a method for decreasing the resistance to fluid flow in a subterranean formation around a well having unpreforated casing fixed therein, the casing extending at least partially through the formation. It comprises providing a liquid in the casing opposite the formation to be treated; placing perforating means in the casing at a depth opposite the formation to be treated; injecting gas into the well until the pressure in the liquid opposite the formation to be treated will be at least as large as the fracturing pressure of the formation when the liquid pressure is applied to the formation; activating the perforating means; and at a time before pressure in the well at the depth of the formation to be treated has substantially decreased, injecting fluid at an effective rate to fracture the formation.

    Duodenal perforation after a blunt abdominal trauma is a rare emergency situation that can result in life-threatening complications. We report on a woman who had a perforation of the duodenum after a supposed mild blunt abdominal trauma. Unremarkable at the initial presentation, the patient presented with acute abdominal pain and a retroperitoneal abscess five days after the initial trauma. The duodenal repair was performed with a Roux-Y anastomosis. Difficulties in diagnosis are very common, but the early recognition of the rupture is essential. The contrast-enhanced CT scan is the gold standard for diagnosis. Surgical management depends on the severity of the trauma and must be chosen on an individual basis.

    During a thirty month period, 319 patients underwent open heart operations, and of these, three experienced a life-threatening explosive abdominal catastrophe. Aggressive radiographic maneuvers established the diagnosis of gastroduodenal perforation. Appropriate abdominal surgery with plication of the perforation and, whenever possible, the establishment of tube gastrostomy for decompression and a tube jejunostomy for feeding is desirable. All three patients required mechanical ventilatory support and tracheostomy prior to the abdominal catastrophe. Prophylactic antacids and sedation seem appropriate, particularly for selected patients (those with a prior peptic history and those with pulmonary dysfunction). Pulmonary toilet for those identified by preoperative pulmonary screening may circumvent the need for postoperative ventilatory support, which increases the risk of stress ulceration. Of the three patients described, all survived the gastrointestinal surgery but only one left the hospital. One died twenty days and another forty-eight days after the intestinal surgery, both of pneumonitis and septicemia.

    Thyroid storm is a rare and life-threatening complication of thyrotoxicosis that requires prompt treatment. Thyroid storm is also known to be associated with precipitating events. The simultaneous treatment of thyroid storm and its precipitant, when they are recognized, in a patient is recommended; otherwise such disorders, including thyroid storm, can exacerbate each other. Here we report the case of a thyroid storm patient (a 55-year-old Japanese male) complicated with a perforated duodenal ulcer. The patient was successfully treated with intensive treatment for thyroid storm and a prompt operation. Although it is believed that peptic ulcer rarely coexists with hyperthyroidism, among patients with thyroid storm, perforation of a peptic ulcer has been reported as one of the causes of fatal outcome. We determined that surgical intervention was required in this patient, reported despite ongoing severe thyrotoxicosis, and reported herein a successful outcome.

    Perforation of the gastrointestinal system by a foreign body is seldom observed in clinical practice; however, it has great importance because it is preventable and can usually be easily treated. In this case report, we present a young male patient, who mistakenly swallowed a foreign body and presented to the emergency service one day later with acute abdomen. The 23-year-old patient was diagnosed with acute appendicitis and underwent emergency laparotomy. During the operation, a plastic object that perforated the terminal ileum lumen and protruded into the abdominal cavity was identified. Along with appendectomy, the foreign body was removed and the ileum was repaired. The detailed history of the patient revealed that he had mistakenly swallowed something one day before the onset of abdominal pain. The patient was discharged on the postoperative seventh day following an uneventful course. PMID:26170746

    The patient with inflammatory bowel disease will be predisposed to numerous infections due their immune status. It is therefore important to understand the immune and serologic status at diagnosis and to put the patient into an adapted vaccination program. This program would be applied differently according to two patient groups: the immunocompromised and the non-immunocom-promised. In general, the first group would avoid the use of live-virus vaccines, and in all cases, inflammatory bowel disease treatment would take precedence over vaccine risk. It is important to individualize vaccination schedules according to the type of patient, the treatment used and the disease pattern.In addition, patient with inflammatory bowel disease should be considered for the following vaccines: varicella vaccine, human papilloma virus, influenza, pneumococcal polysaccharide vaccine and hepatitis B vaccine.

    Acute bowel obstruction due to ingested foreign body (FB) like sharp bone fragment is a rare entity. As preoperative diagnosis was uncertain due to lack of proper history, diagnosis is usually done intraoperatively. Even though it is rare, we should consider it as differential diagnosis in patients with recent dietary history. Herein, we are reporting a 38-year-old man, without any psychiatric illness or previous surgery presenting to emergency department with the features of acute bowel obstruction. CT scan shows high density object in ileum suspicious of foreign body. Patient underwent exploratory laparatomy which reveals dilated small bowel with sharp bony object in ileum, which was retrieved with enterotomy.

    Background: The proper digital arteries as any other axial vessel give rise to multiple cutaneous perforators either volar or dorsal along their course. Their identification is performed with Doppler flowmetry. The vasculo-cutano-tendino-osseous complex (VCTOC), which was described by the senior authors, was responsible for the vascularization of all digital anatomic structures (extensor apparatus, skin, periosteum). Their consistent appearance to well measured distances from the digital joints led the way to the present clinical study for highlighting this described anatomy in-vivo and demonstrating the predictability in digital artery perforator (DAP) flap harvest. Methods: From November 2012 to March 2014, fifteen patients underwent reconstruction with a predictable pattern digital artery perforator flap (PPDAP), based on the previously described VCTOC mapping, for digital lesions secondary to tumor extirpation. Flaps were designed as V-Y advancement or propeller type. Postoperative control concerned flap viability and digital function. Results: Seven males and 8 females underwent elective surgery using PPDAP flaps for digital defects following tumor extirpation. The diameter of the defect ranged from 0.5 to 1.5 cm. The vast majority of the lesions were identified on the right hand, the index, the ring finger and the distal phalanx. All flaps survived without signs of venous congestion. No functional digital problems were observed during follow up (mean of 77 months). A minor wound dehiscence presented in one patient. Conclusions: Authors introduced the concept of a “predictable pattern” in the surgery of perforator flaps in the digits. These flaps are reliable and could be a valuable reconstructive option.

    We examined the latex surgical gloves used by 56 primary surgeons in 454 ophthalmic surgical procedures performed over a 7-month period. Of five techniques used to detect pinholes, air inflation with water submersion and compression was found to be the most sensitive, yielding a 6.80% prevalence in control glove pairs and a 21.8% prevalence in postoperative study glove pairs, for a 15.0% incidence of surgically induced perforations (P = 0.000459). The lowest postoperative perforation rate was 11.4% for cataract and intraocular lens surgery, and the highest was 41.7% for oculoplastic procedures. Factors that correlated significantly with the presence of glove perforations as determined by multiple logistic regression analysis were oculoplastic and pediatric ophthalmology and strabismus surgical procedures, surgeon's status as a fellow in training, operating time, and glove size. The thumb and index finger of the nondominant hand contained the largest numbers of pinholes. These data suggest strategies for reducing the risk of cross-infection during ophthalmic surgery.

    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 <) in distal canals of first and second mandibular molar teeth. After enlargement of root canals using the crown-down pressureless 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.

    Background Self-expanding metal stents (SEMS) are increasingly used in the treatment of malignant large bowel obstruction in the setting of inoperable colorectal cancer. Perforation is a well-known complication associated with these devices. The addition of the vascular endothelial growth factor inhibitor bevacizumab is suspected to increase the rate, but the extent of the increase is not known. Methods We retrospectively reviewed the records of patients receiving SEMS in tertiary hospitals in Calgary, Alta., between October 2001 and January 2012. Results We reviewed the records of 87 patients with inoperable colorectal cancer who received SEMS during our study period. Nine perforations occurred in total: 4 of 30 (13%) patients who received no chemotherapy, 3 of 47 (6%) who received chemotherapy but no bevacizumab, and 2 of 10 (20%) who received chemotherapy and bevacizumab. These two patients received bevacizumab with FOLFIRI after SEMS placement, and they had peritoneal disease. Conclusion Our case series and other studies suggest that bevacizumab may increase the risk of colonic perforation in the setting of SEMS. Caution should be used when combining these therapies.

    Bowel obstruction due to bezoars (compaction of ingested material within the gastrointestinal tract) is a rare, but well documented occurrence. In this paper, we present two cases of potato-induced small bowel obstruction. Both patients were approximately 50 years old and had cerebral palsy and learning disabilities, respectively. They presented with abdominal pain and bilious vomiting, with no medical or surgical history. Diagnosis of small bowel obstruction was confirmed by CT prior to taking the patients to the operating theatre, where whole potatoes were found to be obstructing each patient's bowel lumen. Both patients underwent laparotomy with enterotomy and removal of the potato. They both made a good recovery. Through a literature review of bezoar-induced bowel obstruction, these cases highlight important diagnostic and management principles.

    Transmural migrated retained sponges usually impact at the level of the ileo-cecal valve leading to a small bowel obstruction. Once passed through the ileo-cecal valve, a retained sponge can be propelled forward by peristaltic activity and eliminated with feces. We report the case of a 52-year-old female with a past surgical history and recurrent episodes of abdominal pain and constipation. On physical examination, a generalized resistance was observed with tenderness in the right flank. Contrast-enhanced multi-detector computed tomography findings were consistent with a perforated right colonic diverticulitis with several out-pouchings at the level of the ascending colon and evidence of free air in the right parieto-colic gutter along with an air-fluid collection within the mesentery. In addition, a ring-shaped hyperdense intraluminal material was also noted. At surgery, the ascending colon appeared irregularly thickened and folded with a focal wall interruption and a peri-visceral abscess at the level of the hepatic flexure, but no diverticula were found. A right hemi-colectomy was performed and on dissection of the surgical specimen a retained laparotomy sponge was found in the bowel lumen.

    Small bowel imaging and endoscopy in inflammatory bowel disease (IBD) underwent a lot of change and advancement in the recent years. Modalities have shifted from gastroscopy, colonoscopy and small bowel follow through, to ileo-colonoscopy, computed tomography (CT) or magnetic resonance (MR), enteroscopy, wireless video capsule endoscopy and balloon assisted enteroscopy. Nowadays endoscopy has a major role in the diagnosis of IBD, assessing its extent, treating some of its complications (stricture, bleeding), assessing the success of various treatments (mucosal healing), and as a predictor of disease course. Wireless capsule endoscopy (WCE) is a relatively new "toy" allowing direct, patient friendly, visualization of the entire small bowel mucosa. It has gained a substantial role in the evaluation of patients with suspected Chron's Disease (CD) and indeterminate colitis. WCE has a high positive predictive value in patients with suspected CD, when one uses more than two of the International Conference on Capsule Endoscopy (ICCE) criteria, and not less important, a very high negative predictive value in patients with suspected CD. Its role in patients with known CD, assessing their disease activity and extent, its role in assessing postsurgical small bowel recurrence and its role in the evaluation of mucosal healing are still unclear. Balloon assisted enteroscopy has established its role as a complementary tool in cases where there is need of biopsies or treatment (dilatation of strictures). The present review will summarize the role of endoscopy in the diagnosis of IBD, in assessing its activity, its management, interventional endoscopy and cancer surveillance.

    Perforating dermatoses are a group of skin diseases characterized by transepidermal elimination of dermal material. The disease is divided into two groups: the primary group and the secondary group. The classical or primary perforating dermatoses are subdivided into four types according to the eliminated dermal materials: Kyrle disease, perforating reactive collagenosis, elastosis perforans serpiginosa, and perforating folliculitis. The secondary form is known as acquired perforating dermatosis. The term was proposed in 1989 by Rapini to designate the perforating dermatoses affecting adult patients with systemic disease, regardless of the dermal materials eliminated. This report describes a case of the disease with elimination of collagen and elastic fibers in a patient with chronic renal failure. PMID:28300880

    A study was conducted to determine the effects of high speed grazing air flow on the acoustic resistance of perforated sheet materials used in the construction of acoustically absorptive liners placed in commercial aircraft engine nacelles. Since DC flow resistance of porous sheet materials is known to be a major component of the acoustic resistance of sound suppression liners, the DC flow resistance of a set of perforated face-sheets and linear 'wiremesh' face-sheets was measured in a flow duct apparatus (up to Mach 0.8). Samples were fabricated to cover typical variations in perforated face-sheet parameters, such as hole diameter, porosity and sheet thickness, as well as those due to different manufacturing processes. The DC flow resistance data from perforated sheets were found to correlate strongly with the grazing flow Mach number and the face-sheet porosity. The data also show correlation against the boundary layer displacement thickness to hole-diameter ratio. The increase in resistance with grazing flow for punched aluminum sheets is in good agreement with published results up to Mach 0.4, but is significantly larger than expected above Mach 0.4. Finally, the tests demonstrated that there is a significant increase in the resistance of linear 'wiremesh' type face-sheet materials.

    Ingested fish bone induced intestinal perforations are seldom diagnosed preoperatively due to incomplete patient history taking and difficulties in image evidence identification. Most literature suggests early surgical intervention to prevent sepsis and complications resulting from fish bone migrations. We report the case of a 44-year-old man suffered from acute abdomen induced by a fish bone micro-perforation. The diagnosis was supported by computed tomography (CT) imaging of fish bone lodged in distal ileum and a history of fish ingestion recalled by the patient. Medical treatment was elected to manage the patient's condition instead of surgical intervention. The treatment resulted in a complete resolution of abdominal pain on hospital day number 4 without complication. Factors affecting clinical treatment decisions include the nature of micro-perforation, the patient's good overall health condition, and the early diagnosis before sepsis signs develop. Micro-perforation means the puncture of intestine wall without CT evidence of free air, purulent peritoneum or abscess. We subsequently reviewed the literature to support our decision to pursue medical instead of surgical intervention.

    Rectal perforations due to glycerin enemas (GE) typically occur when the patient is in a seated or lordotic standing position. Once the perforation occurs and peritonitis results, death is usually inevitable. We describe two cases of rectal perforation and fistula caused by a GE. An 88-year-old woman presented with a large rectal perforation and a fistula just after receiving a GE. Her case was further complicated by an abscess in the right rectal wall. The second patient was a 78-year-old woman who suffered from a rectovesical fistula after a GE. In both cases, we performed direct endoscopic abscess lavage with a saline solution and closed the fistula using an over-the-scope-clip (OTSC) procedure. These procedures resulted in dramatic improvement in both patients. Direct endoscopic lavage and OTSC closure are very useful for pararectal abscess lavage and fistula closure, respectively, in elderly patients who are in poor general condition. Our two cases are the first reports of the successful endoscopic closure of fistulae using double OTSCs after endoscopic lavage of the debris and an abscess of the rectum secondary to a GE.

    Perforations and leakages of hollow organs of the gastrointestinal tract can occur spontaneously among other causes. They can also develop as complications of an endoscopic intervention or after surgical construction of an anastomosis. For the patient, these situations usually are serious and life-threatening. Standard therapy has always been - and most of the time still is - major surgery. These procedures usually are technically difficult and their mortality and morbidity are not satisfactory due to, among others, the occurrence of local infections. Thus, various endoscopic techniques as therapy for perforations and leakages have been developed over the last years. These include above all the endoscopic placement of clip systems and stents and the relatively new vacuum drainage systems. In case of perforations and leakages of the bile duct and the rectum especially, these minimal invasive techniques are widely used, also increasingly in lesions of the esophagus. However, these new, endoscopic procedures suffer from a lack of evidence. This paper highlights the possibilities and limitations of endoscopic options in therapy for perforations and leakages of organs of the gastrointestinal tract.

    Sonography is not the method of choice for the evaluation of suspected peptic ulcer perforation (PUP). However, indirect sonographic signs and direct visualization of PUP have been reported by several authors in recent years. We report a case of an elderly woman who presented with severe abdominal pain and positive rebound sign, in whom abdominal sonography demonstrated indirect signs of PUP, the site of perforation, and active air fluid leakage through the perforated anterior prepyloric antral wall.

    Gallbladder perforation is a serious clinical condition. A definitive diagnosis is contentious before surgery. We discuss a case where a young patient with Crohn's disease taking oral steroids presented with an acute abdomen. CT scan demonstrated a perforated gallbladder without evidence of gallstones. The patient underwent an emergency cholecystectomy and peritoneal lavage. The history and clinical findings of this patient are reviewed to highlight perforation of the gallbladder in relation to steroid therapy.

    Inflammatory Bowel Diseases - ulcerative colitis and Crohn's disease- are chronic gastrointestinal inflammatory diseases of unknown etiology. Decreased oral intake, malabsorption, accelerated nutrient losses, increased requirements, and drug-nutrient interactions cause nutritional and functional deficiencies that require proper correction by nutritional therapy. The goals of the different forms of nutritional therapy are to correct nutritional disturbances and to modulate inflammatory response, thus influencing disease activity. Total parenteral nutrition has been used to correct and to prevent nutritional disturbances and to promote bowel rest during active disease, mainly in cases of digestive fistulae with high output. Its use should be reserved for patients who cannot tolerate enteral nutrition. Enteral nutrition is effective in inducing clinical remission in adults and promoting growth in children. Due to its low complication rate and lower costs, enteral nutrition should be preferred over total parenteral nutrition whenever possible. Both present equal effectiveness in primary therapy for remission of active Crohn's disease. Nutritional intervention may improve outcome in certain individuals; however, because of the costs and complications of such therapy, careful selection is warranted, especially in patients presumed to need total parenteral nutrition. Recent research has focused on the use of nutrients as primary treatment agents. Immunonutrition is an important therapeutic alternative in the management of inflammatory bowel diseases, modulating the inflammation and changing the eicosanoid synthesis profile. However, beneficial reported effects have yet to be translated into the clinical practice. The real efficacy of these and other nutrients (glutamine, short-chain fatty acids, antioxidants) still need further evaluation through prospective and randomized trials.

    Small bowel obstruction (SBO) due to intussusception in adults is a rare condition. Diagnosis at the time of admission is usually challenging. More often than not, a bowel intussusception in adults is secondary to an organic condition, frequently malignancies. Therefore, a surgical approach is indicated most of the times. We report the case of a forty-nine years old lady presenting with a SBO secondary to small bowel metastases with two ileo-ileal intussusceptions, one of which was missed at initial surgical exploration. A giant cell carcinoma of the lung (GCCL) with small bowel metastases was diagnosed subsequently. The case is presented as well as a brief review of literature.

    Root perforations are an undesired complication of endodontic treatment which result in loss of integrity of the root, and adversely affect the prognosis of the treatment. Recently, Iranian mineral trioxide aggregate [Root MTA] has been introduced as an ideal material for perforation repair. In this article a successful repair of strip root perforation of mandibular molar using Root MTA is presented with 15-month follow-up. This case suggests that Root MTA may be a substitute material for the treatment of strip perforation; however, more clinical studies with larger sample size and longer follow-ups are needed.

    Acquired reactive perforating collagenosis is a perforating dermatosis usually associated with different systemic diseases, mainly diabetes mellitus and/or chronic renal insufficiency. Different therapies have been tried but treatment is not standardized yet and remains a challenge. In the last few years, allopurinol has been reported as a good therapeutic option for acquired reactive perforating collagenosis. We describe the case of a 73-year-old man affected by acquired reactive perforating collagenosis associated with diabetes type 1 and chronic renal failure with secondary hyperparathyroidism. The patient was successfully treated with allopurinol 100mg once/day p.o.. PMID:23539010

  1. Spontaneous free perforation of the small intestine in adults

    2014-01-01

    Spontaneous free perforation of the small intestine is uncommon, especially if there is no prior history of visceral trauma. However, free, even recurrent, perforation may complicate a defined and established clinical disorder, such as Crohn’s disease. In addition, free perforation may be the initial clinical presentation of an occult intestinal disorder, such as a lymphoma complicating celiac disease, causing diffuse peritonitis and an acute abdomen. Initial diagnosis of the precise cause may be difficult, but now has been aided by computerized tomographic imaging. The site of perforation may be helpful in defining a cause (e.g., ileal perforation in Crohn’s disease, jejunal perforation in celiac disease, complicated by lymphoma or collagenous sprue). Urgent surgical intervention, however, is usually required for precise diagnosis and treatment. During evaluation, an expanding list of other possible causes should be considered, even after surgery, as subsequent management may be affected. Free perforation may not only complicate an established intestinal disorder, but also a new acute process (e.g., caused by different infectious agents) or a longstanding and unrecognized disorder (e.g., congenital, metabolic and vascular causes). Moreover, new endoscopic therapeutic and medical therapies, including use of emerging novel biological agents, have been complicated by intestinal perforation. Recent studies also support the hypothesis that perforation of the small intestine may be genetically-based with different mutations causing altered connective tissue structure, synthesis and repair.

    The incorporation of perforated cortical bone allografts was compared with non-perforated allografts. A 5-cm circumferential defect in the middiaphysis at the tibia was created in adult sheep. A frozen tibial allograft was implanted and fixed with a locked nail for 6 months. There was no postoperative immobilization. Group I consisted of eight sheep with non-perforated allografts, whereas Group II was comprised of 10 sheep with perforated allografts. Union was evaluated radiographically, whereas the central part of the allograft had a densitometric evaluation. Creeping substitution was assessed on microradiographs from cross-sections of the central 3 cm of graft by measurement of porosity and percentage of new and old bone area within the confines of the graft. The width of periosteal and endosteal callus also was determined. There was no statistical difference between both groups for the union score and bone density. However, the cortical bone graft porosity and the amount of new bone within the cortical bone differed significantly between the perforated allografts and the non-perforated ones. Periosteal callus was similar in both groups, whereas endosteal callus was significantly more wide and extended in the perforated allografts. Perforation of a cortical bone substantially improved the amount of newly formed bone by the host when compared with a non-perforated bone. The creation of channels seemed to increase the interface between living soft tissues of the host and the allografted bone with a resulting enhanced incorporation.

    Iatrogenic colon perforation is one the most pernicious complications for patients undergoing endoscopic screening or therapy. It is a serious but rare complication of colonoscopy. However, with the expansion of the indications for endoscopic therapies for gastrointestinal diseases, the frequency of colorectal perforation has increased. The management of iatrogenic colorectal perforation is still a challenge for many endoscopists. The methods for treating this complication vary, including conservative treatment, surgical treatment, laparoscopy and endoscopy. In this review, we highlight the etiology, recognition and treatment of colorectal iatrogenic perforation. Specifically, we shed light on the endoscopic management of this rare complication.

    Iatrogenic perforation of the upper gastrointestinal tract is one of the most serious complications of upper gastrointestinal endoscopy, with high rates of morbidity and mortality. Treatment is challenging because stent placement or surgical repair of the perforation in this area is often impossible. We report on two cases of iatrogenic perforations of the very proximal oesophagus and distal hypopharynx which could be successfully closed by using an endoluminal vacuum sponge treatment for 5 days. Thus, the endoluminal vacuum therapy may be a useful alternative to surgery in such cases of difficultly managable perforations of the upper oesophagus.

    One hundred and two patients with perforated duodenal ulcers over a 13 year period (1970 to 1982) have been prospectively followed-up at a special gastric clinic. Of the 37 patients with perforation of their acute ulcer, 34 were treated by oversew and three had an initial definitive operation (vagotomy and drainage). The remaining 65 patients presented with perforation of a chronic ulcer and 54 were treated by oversew and 11 underwent definitive surgery--nine had vagotomy and drainage and two had partial gastrectomies. Seven of the 34 patients (20.5%) with acute ulcer perforation treated by simple oversew subsequently required definitive ulcer surgery at a mean 17.5 months after perforation and 31 of the 54 patients (57.4%) with chronic ulcer perforations required definitive surgery at a mean 27.4 months after perforation. The introduction of H2 antagonists in 1977 did not alter the re-operation rate in patients with chronic ulcer perforation managed by oversew. Results of this study provide further evidence in favour of treating patients with perforation of their chronic duodenal ulcer by definitive surgery whenever possible. PMID:3789618

An ideal biomarker with the characters such as simple, easy to perform, noninvasive or microinvasive, cheap, rapid, and reproducible is helpful for patients and clinicians. Currently biomarkers applied in clinic include CRP, ESR, pANCA, ASCA, and fecal calprotectin. However, they are far from ideal. Lots of studies are focused on seeking for ideal biomarker for IBD.

    Purpose of review The review aims to update the reader on current developments in our understanding of how the gut microbiota impact on inflammatory bowel disease and the irritable bowel syndrome. It will also consider current efforts to modulate the microbiota for therapeutic effect. Recent findings Gene polymorphisms associated with inflammatory bowel disease increasingly suggest that interaction with the microbiota drives pathogenesis. This may be through modulation of the immune response, mucosal permeability or the products of microbial metabolism. Similar findings in irritable bowel syndrome have reinforced the role of gut-specific factors in this ‘functional’ disorder. Metagenomic analysis has identified alterations in pathways and interactions with the ecosystem of the microbiome that may not be recognized by taxonomic description alone, particularly in carbohydrate metabolism. Treatments targeted at the microbial stimulus with antibiotics, probiotics or prebiotics have all progressed in the past year. Studies on the long-term effects of treatment on the microbiome suggest that dietary intervention may be needed for prolonged efficacy. Summary The microbiome represents ‘the other genome’, and to appreciate its role in health and disease will be as challenging as with our own genome. Intestinal diseases occur at the front line of our interaction with the microbiome and their future treatment will be shaped as we unravel our relationship with it. PMID:24296462

    The short bowel syndrome appears for the reduction of intestinal absorptive surface due to functional or anatomical loss of part of the small bowel. We present the case of a 35-year-old woman with severe short bowel syndrome secondary to acute intestinal ischemia in adults, who presented at 5 years of evolution episodes of dizziness with gait instability and loss of strength in hands. The diagnosis was D-lactic acidosis. D-lactic acidosis is a rare complication, but important for their symptoms, of this syndrome. It is due to a change in intestinal flora secondary to an overgrowth of lactic acid bacteria that produce D-lactate. D-lactic acidosis should be looked for in cases of metabolic acidosis in which the identity of acidosis is not apparent, neurological manifestations without focality and the patient has short bowel syndrome or patients who have had jejunoileal bypass surgery. Appropriate treatment usually results in resolution of neurologic symptoms and prevents or reduces further recurrences.

    Ascites is more difficult to detect when only a small quantity is present. The aim of this pilot study was to determine the optimal bowel sound characteristics in order to distinguish no ascites from small-volume ascites by advanced processing of bowel sound wave patterns. This analysis results in the definition of the normal range of bowel sound patterns, thus providing a novel, simple, and noninvasive way of determining on abnormal pattern, which may reflect presence of small volume ascites. Cirrhotic patients with radiologically proven small-volume ascites and a control group were subjected to bowel sound recordings. The latter were analyzed using a denoising wavelet transform-based filter and a higher-order crossings-based technique in a blinded fashion for linearly distinguishing the two classes. Scatter plots of third-order zero crossings reflect distinct changes seen in the denoised bowel sound pattern between patients and controls due to altered transmission path, providing a distinct separation of all cirrhotic patients with small ascites from controls (P < 0.0001). We conclude that the proposed bowel sounds analysis appears to provide new information regarding the changes of the bowel sound patterns due to the presence of small-volume ascites, potentially contributing towards a safe, effective, noninvasive, and easily implemented alternative method for the diagnosis of small volume ascites at the bedside.

    Short bowel syndrome is a complex clinical picture, characterized by signs and symptoms of malabsorption and subsequent malnutrition, which often occurs after extensive bowel resections. Short bowel syndrome's treatment must begin together with the planning of the first surgery, especially for disease that may need multiple interventions. Patients with short bowel should be individually managed because they all are different in diagnosis, length of the remaining bowel and in psychosocial characteristics. For all these reasons, a multidisciplinary approach between the various specialists is therefore needed.

    2008-05-01

    Reconstruction of large-sized lumbosacral or sacral defects often is not possible using local or regional flaps, making the use of free flaps necessary. However, the difficulty of any microsurgical procedure in this region is complicated by the need to search for potential recipient vessels to revascularize the flap. In the present case, a free musculocutaneous anterolateral thigh flap to cover a large-sized and deep lumbosacral defect was used. Arterial anastomosis was performed, connecting the cutaneous anterolateral thigh (ALT) perforator to the perforator of the second lumbar artery. In this fashion, the arterial circulation through the flap was flowing reversely through the muscle. The concomitant vein of the descending branch of the lateral circumflex femoral artery was hooked up to the thoracodorsal vein using a long interposition vein graft because the perforator of the second lumbar vein was too small. Postoperative healing was uneventful. In conclusion, a successful reconstruction of a lumbar defect has shown that local perforators in the lumbar area may be accessible for easier perforator-to-perforator anastomoses and that the muscular part of the musculocutaneous ALT flap can survive on retrograde arterial perfusion from a perforator of the skin island.

    A downhole tool, adapted to retain a shaped charge surrounded by a superatmospherically pressurized light gas, is employed in a method for perforating a casing and penetrating reservoir rock around a wellbore. Penetration of a shaped charge jet can be enhanced by at least 40% by imploding a liner in the high pressure, light gas atmosphere. The gas pressure helps confine the jet on the axis of penetration in the latter stages of formation. The light gas, such as helium or hydrogen, is employed to keep the gas density low enough so as not to inhibit liner collapse.

The clinical manifestations of EPTB may be non-specific that mimics other diseases and is usually misdiagnosed. Therefore, high clinical suspicion of EPTB infection is important, especially in endemic areas. Here, we present a case of hard palate perforation that proved to be tuberculous in origin.

    Aims To determine the frequency of choroidal detachment (CD) in eyes with non‐traumatic corneal ulcer perforation and, also, to assess the efficacy and safety of cyanoacrylate glue in sealing corneal perforations. Methods 18 eyes of 17 patients were studied. Inclusion criterion was any patient with a non‐traumatic perforated corneal ulcer. All patients had a thorough history taken and complete ophthalmic examination including B‐scan ultrasonography. Patient demographics, presence of CD, and efficacy of corneal gluing were assessed. Results Eight of the 18 eyes (44%) were documented to have a CD. Among perforations of >2 mm2, six eyes (75%) were documented to have CD compared with two eyes (20%) with perforations of ⩽2 mm2 (p = 0.054). No correlation could be determined between perforation duration and incidence of CD. Of the 15 eyes that underwent gluing, there were 13 successes (87%) and two failures (13%). Within the successes four patients (27%) required re‐gluing because of infection (one patient) or progression of melt and glue loosening (three patients). Failure was the result of severe progression of melting (one patient) and a very large perforation (one patient). Conclusion Choroidal detachment following corneal ulcer perforation is common and is more likely in larger corneal perforations. Preoperative B‐scan should be considered in cases of large corneal perforations requiring therapeutic keratoplasty to document choroidal detachment, which if large may require drainage. Cyanoacrylate glue is an effective and safe method for sealing small corneal perforations. A vigil must be maintained for infection while the glue and bandage contact lens are in situ. PMID:16723362

    There are two common types of adult patient with a short bowel, those with jejunum in continuity with a functioning colon and those with a jejunostomy. Both groups have potential problems of undernutrition, but this is a greater problem in those without a colon, as they do not derive energy from anaerobic bacterial fermentation of carbohydrate to short chain fatty acids in the colon. Patients with a jejunostomy have major problems of dehydration, sodium and magnesium depletion all due to a large volume of stomal output. Both types of patient have lost at least 60 cm of terminal ileum and so will become deficient of vitamin B(12). Both groups have a high prevalence of gallstones (45%) resulting from periods of biliary stasis. Patients with a retained colon have a 25% chance of developing calcium oxalate renal stones and they may have problems with D(-) lactic acidosis. The survival of patients with a short bowel, even if they need long-term parenteral nutrition, is good.

    Patients with burn scars often experience functional problems because of scar contractures. Surgical treatment may be indicated for those burn scar contractures. If the contractures are small and linear, the contraction bands can be treated with local transposition flaps like the Z-plasty. Broader, diffuse contractures are more challenging and require a different surgical approach, such as the use of local tissue. The use of perforator-based flaps is promising; however, their true clinical significance for this type of burn reconstructions still needs to be determined. Therefore, we performed a review to evaluate the role of perforator-based flaps for burn scar contracture treatment. Electronic databases were searched using a predefined search strategy. Studies evaluating the long-term outcome of perforator-based flaps for the treatment of burn scar contractures were included. The methodological quality was tested and data was summarized. Five hundred and ten papers were identified of which eleven met the inclusion criteria. One study was a randomized controlled trial; ten were cohort studies of a pre-postoperative design. The papers described outcomes of free flaps and local flaps. Most studies had methodological shortcomings and used inappropriate statistical methods. Perforator-based interposition flaps appear to be highly relevant for burn scar contracture treatment. However, due to the paucity and low quality of the studies that were assessed, no definitive conclusions about the true clinical significance could be reached. And therefore, only recommendations could be given for improvement of the quality of further primary research on the effectiveness of perforator-based flaps for burn scar contracture release.

    Intestinal ischemia, which refers to insufficient blood flow to the bowel, is a potentially catastrophic entity that may require emergent intervention or surgery in the acute setting. Although the clinical signs and symptoms of intestinal ischemia are nonspecific, CT findings can be highly suggestive in the correct clinical setting. In this chapter we review the CT diagnosis of arterial, venous, and non-occlusive intestinal ischemia. We discuss the vascular anatomy, pathophysiology of intestinal ischemia, CT techniques for optimal imaging, key and ancillary radiological findings, and differential diagnosis. In the setting of an acute abdomen, rapid evaluation is necessary to identify intraabdominal processes that require emergent surgical intervention (1). While a wide-range of intraabdominal diseases may be present from trauma to inflammation, one of the most feared disorders is mesenteric ischemia, also known as intestinal ischemia, which refers to insufficient blood flow to the bowel (2). Initial imaging evaluation for intestinal ischemia is typically obtained with CT. Close attention to technique and search for key radiologic features with relation to the CT technique is required. Accurate diagnosis depends on understanding the vascular anatomy, epidemiology, and pathophysiology of various forms of mesenteric ischemia and their corresponding radiological findings on MDCT. At imaging, not only is inspection of the bowel itself important, but evaluation of the mesenteric fat, vasculature, and surrounding peritoneal cavity also helps improves accuracy in the diagnosis of bowel ischemia.

    We present the case of young female patient presenting with acute onset abdominal pain. Abdominopelvic CT revealed herniation through the foramen of Winslow. The patient was transferred to our hospital and underwent laparoscopic exploration. Though spontaneous reduction was detected, segmental resection of the impacted small bowel was inevitable due to ischemic change. Our case suggests that reducing the time until surgery is very important to lower the probability of bowel resection in case of small bowel herniation through the foramen of Winslow. PMID:28203560

    Rochette described the perforated cast metal bonded design for splinting periodontally compromised teeth. The design was later used for replacing missing teeth. The main causes of failure of the perforated (Rochette) type design were attributed to inappropriate case selection and erosion of the composite from perforations. The aim of this study was to analyse the effect of stress magnitude and direction on failure of perforated resin bonded bridges (RBBs). The objective was to compare stress magnitudes in this design with those reported on the non-perforated RBBs. Photoelastic modelling materials were selected to represent the relative stiffnesses of a posterior mandibular and an anterior maxillary perforated (Rochette) type design. The sizes of the models were scaled to x 2.5 in order to enhance visual analysis of the stress patterns. Stress magnitudes were quantified from isochromatic fringes and stress directions were evaluated from stress trajectories. These revealed a high-stress concentration around the perforations, particularly for those at the proximo-lingual/palatal (connector) areas. This experimental study revealed that the main reason for failure of Rochette designs is deformation at the perforations.

    Completion of cased and cemented wells by shaped-charge perforation results in damage to the formation, which can significantly reduce well productivity. Typically, underbalanced conditions are imposed during perforation in an effort to remove damaged rock and shaped-charge debris from the perforation tunnel. Immediately after the shaped-charge jet penetrates the formation, there is a transient surge of fluid from the formation through the perforation and into the well bore. Experimental evidence suggests that it is this transient pressure surge that leads to the removal of damaged rock and charge debris leaving an open perforation tunnel. We have developed a two-stage computational model to simulate the perforation process and subsequent pressure surge and debris removal. The first stage of the model couples a hydrocode with a model of stress-induced permeability evolution to calculate damage to the formation and the resulting permeability field. The second stage simulates the non-Darcy, transient fluid flow from the formation and removes damaged rock and charge debris from the perforation tunnel. We compare the model to a series of API RP43 section 4 flow tests and explore the influence of fluid viscosity and rock strength on the final perforation geometry and permeability.

    Ingestion of gastrointestinal (GI) foreign bodies represents a challenging clinical scenario. The greater risk is at extremes of age, in those wearing dentures, alcoholics and mentally handicapped. We present a case of duodenal perforation caused by a bird feather. A 64-year-old man was presented with abdominal pain for 4 days. Abdominal examination showed signs of peritonitis. The erect abdominal x-ray showed free gas under diaphragm. Exploratory laparotomy showed purulent fluid, but no definite site of perforation could be found. So the abdomen was closed with a drain in Morison's pouch. The postoperative recovery was uneventful. He came for a repeat check-up at 4 weeks with dull aching pain in the upper abdomen and was advised for a routine upper GI endoscopy which revealed a feather penetrating the first part of the duodenum, which was removed with a foreign body removing forceps. GI foreign bodies represent a significant problem and an increased level of suspicion is important for timely diagnosis and treatment.

    2000-01-01

    The present work explored the feasibility of controlling the acoustic impedance of a resonant type acoustic liner. This was accomplished by translating one perforate over another of the same porosity creating a totally new perforate that had an intermediate porosity. This type of adjustable perforate created a variable orifice perforate whose orifices were non-circular. The key objective of the present study was to quantify, the degree of attenuation control that can be achieved by applying such a concept to the buried septum in a two-degree-of-freedom (2DOF) acoustic liner. An additional objective was to examine the adequacy of the existing impedance models to explain the behavior of the unique orifice shapes that result from the proposed silding perforate concept. Different orifice shapes with equivalent area were also examined to determine if highly non-circular orifices had a significant impact on the impedance.

    To perforate tissue lying deep part in body, a large size transducer was assembled by combining four spherical-shaped transducers, and the optimal conditions for tissue perforation have studied using ventricle muscle of chicken as a target. The ex vivo experiments showed that ventricle muscle was successfully perforated both when it was exposed to High Intensity Focused Ultrasound (HIFU) directly and when it was exposed to HIFU through atrial muscle layer. Moreover, it was shown that calculated acoustic power distributions are well similar to the perforation patterns, and that the acoustic energy distributes very complexly near the focus. Lastly, perforation on the living rabbit bladder wall was demonstrated as a preliminary in vivo experiment.

    We present an unusual case of necrotizing fasciitis in the upper abdominal wall caused by penetrating perforation of the gallbladder. It was manifested as an elastic and reddish abdominal swelling with severe tenderness, but no peritoneal irritation. Computed tomography (CT) demonstrated water density with a slightly elevated CT value and air bubbles in the subcutaneous space. The preoperative diagnosis was subcutaneous abscess with fasciitis. At surgery, necrotizing fasciitis and subcutaneous abscess secondary to penetrating perforation of the gallbladder were revealed. Cholecystectomy and peritoneal irrigation were performed. Although no tumor was evident during surgery, a tumor located close to the perforation site was found just after the operation. Pathological examination revealed gallbladder carcinoma without stones. There have been very few previous reports of necrotizing fasciitis following gallbladder perforation. The presentation, diagnosis, and management of fasciitis, as well as carcinoma of the gallbladder with perforation, are discussed.

    A set of experiments is carried out in a towing tank to study the effects of the curvature of perforated plates on the wave reflection coefficient ( C r ). The curvature of a perforated plate can be changed by rotating a reference perforated plate aboutits origin according to the parabolic equation y=- x 2. A plunger-type wave maker is used to generate regular waves. The reflection coefficients are calculated using Goda and Suzuki's (1976) method. The results are compared with those of vertical or sloped passive wave absorbers. The comparison shows that a perforated plate with a curved profile is highly efficient in terms of reducing the wave reflection coefficient. A correlation is established to estimate the reflection coefficient of curved perforated plates as a function of both flow and geometry characteristics.

    Incorporation of massive cortical bone allografts in the human is slow and remains incomplete. Late biopsies of implanted allografts or histological studies of explanted allografts always show the partial substitution of necrotic bone by new bone from the host. The aim of the present study was to evaluate the value of drilling the massive deep-frozen cortical allografts in order to induce osteogenesis. Thirteen sheep were operated on and a standard segment of the proximal ulna was removed and the gap filled either by an unperforated allograft or by a perforated one. Based on histological and microradiographic examination, a complete substitution of the perforated allografts was observed but in this model no statistically significant difference was observed between perforated and unperforated allografts. Further study is needed to assess the effect of the perforations.

    Small bowel adenocarcinoma is part of the tumor spectrum of Lynch syndrome, which is caused by germline mutations in the mismatch repair genes. The present study describes the case of a 51-year-old man fulfilling the Amsterdam II criteria for Lynch syndrome, who had a 15-mm early-stage colorectal cancer resected endoscopically from the ascending colon. Due to upper abdominal discomfort after eating and consequent anorexia, a computed tomography scan performed 1 month later showed a tumoral mass of the upper jejunum with local lymphadenopathy. The laparotomy revealed a completely obstructing mass. Intraoperative frozen section showed a small bowel adenocarcinoma. Subsequent genetic testing confirmed the germline mutation of mutL homolog 1. The patient received 6 cycles of an adjuvant folinic acid, fluorouracil and ocaliplatin chemotherapy regimen. The latest CT scan, 16 months after the chemotherapy, did not show any recurrence. This case highlights the importance of considering the possibility of small bowel adenocarcinoma in patients with upper bowel obstruction, particularly for patients with Lynch syndrome.

    An 89-year-old woman with severe aortic valve stenosis and bradycardia presented with circulatory shock due to cardiac tamponade. We performed pericardiocentesis, and then diagnosed right ventricular perforation by echocardiography with microcavitation contrast medium just before inserting a drainage tube. We then inserted the drainage tube in the appropriate position and withdrew blood-filled fluid. The patient was haemodynamically stabilised, but haemorrhage from the perforation site continued for a few days. We injected fibrin glue into the pericardial space through the drainage tube and achieved haemostasis. Thus, we avoided surgery to close the perforation in this high-risk patient. There was no recurrence of haemorrhage. She subsequently had elective aortic valve replacement at another hospital. No adhesions in the pericardial space were seen during surgery.

    Abstract Rationale: Ingestion of a fishbone is a common cause of esophageal injury, but spinal epidural abscess (SEA) is a rare condition due to the esophageal penetration by a swallowed fishbone. Prompt diagnosis can be seldom made owing to incomplete patient history taking and difficulties in imaging evidence identification. Patient concerns: We describe the case of a 62-year-old woman who was stuck in her throat by a fishbone, and complained of back pain, paresis of the lower limbs and fever, successively. To our knowledge, this is the first case report that we know of thoracic SEA caused by fishbone perforation. Diagnoses: About 20 days after the onset of severe back pain, she was diagnosed with SEA based on the clinical presentation and imaging findings. Interventions: Antibiotic therapy and rehabilitation therapy were carried out afterwards. However, due to exacerbation of her condition, surgical intervention had to be taken eventually. Outcomes: It is quite unfortunate for this patient to have a poor prognosis due to a delayed diagnosis and an improper management. Lessons: A number of lessons can be learnt from this case.

    In Crohn disease, bowel-preserving surgery is necessary to prevent short bowel syndrome due to repeated operations. This study aimed to determine the remnant small bowel length cut-off and to evaluate the clinical factors related to nutritional status after small bowel resection in Crohn disease.We included 394 patients (69.3% male) who underwent small bowel resection for Crohn disease between 1991 and 2012. Patients who were classified as underweight (body mass index < 17.5) or at high risk of nutrition-related problems (modified nutritional risk index < 83.5) were regarded as having a poor nutritional status. Preliminary remnant small bowel length cut-offs were determined using receiver operating characteristic curves. Variables associated with poor nutritional status were assessed retrospectively using Student t tests, chi-squared tests, Fisher exact tests, and logistic regression analyses.The mean follow-up period was 52.9 months and the mean patient ages at the time of the last bowel surgery and last follow-up were 31.2 and 35.7 years, respectively.

    2015-12-01

    Ongoing troublesome bowel symptoms despite quiescent inflammatory disease are a frequent management challenge when caring for patients with inflammatory bowel disease (IBD). Even when active disease has been excluded the prevalence of residual gastrointestinal symptoms is surprisingly high and the cause often obscure. The presence of a concurrent functional disorder such as irritable bowel syndrome (IBS) is associated with worse quality of life, worse physical functioning, higher prevalence of anxiety and greater health care utilization. Potential etiological mechanisms leading to the development of IBS like symptoms include the development of visceral hypersensitivity following the original inflammatory insult, alteration in cortical processing, dysbiosis and residual subacute inflammation. Therapeutic options for managing IBS in patients with IBD include dietary modification, interventions targeted at correction of visceral sensory dysfunction or cortical processing and modulation of the gut microbiota. As there are few studies specifically examining the treatment of IBS in patients with IBD, the majority of therapeutic interventions are extrapolated from the IBS literature. Given the frequency of residual functional symptoms in IBS, significantly more research is warranted in this field.

  20. MR Enterography of Inflammatory Bowel Disease with Endoscopic Correlation.

    2017-01-01

    Crohn disease (CD) and ulcerative colitis (UC) are the two main forms of idiopathic inflammatory bowel disease (IBD). CD is a transmural chronic inflammatory disorder that can affect any part of the gastrointestinal tract in a discontinuous distribution. UC is a mucosal and submucosal chronic inflammatory disease that typically originates in the rectum and may extend proximally in a continuous manner. In treating patients with CD and UC, clinicians rely heavily on accurate diagnoses and disease staging. Magnetic resonance (MR) enterography used in conjunction with endoscopy and histopathologic analysis can help accurately diagnose and manage disease in the majority of patients. Endoscopy is more sensitive for detection of the early-manifesting mucosal abnormalities seen with IBD and enables histopathologic sampling. MR enterography yields more insightful information about the pathologic changes seen deep to the mucosal layer of the gastrointestinal tract wall and to those portions of the small bowel that are not accessible endoscopically. CD can be classified into active inflammatory, fistulizing and perforating, fibrostenotic, and reparative and regenerative phases of disease. Although CD has a progressive course, there is no stepwise progression between these disease phases, and various phases may exist at the same time. The endoscopic and MR enterographic features of UC can be broadly divided into two categories: acute phase and subacute-chronic phase. Understanding the endoscopic features of IBD and the pathologic processes that cause the MR enterographic findings of IBD can help improve the accuracy of disease characterization and thus optimize the medication and surgical therapies for these patients.

  1. Report: impact of inflammatory bowel disease.

    PubMed

    Wilhelm, Sheila M

    2016-03-01

    Inflammatory bowel disease (IBD) includes ulcerative colitis (UC) and Crohn's disease (CD), 2 conditions characterized by chronic inflammation. Approximately 1.17 million people in the United States are affected by these 2 conditions. It is theorized that a genetic susceptibility coupled with environmental factors, such as smoking, antibiotics, oral contraceptives, appendectomy, or diet, may influence the development of IBD. Patients with UC and CD may exhibit similar symptoms, and the conditions are often misclassified, as there is a lack of standard criteria for diagnosing IBD. Therefore, it is important for clinicians to rule out any diarrhea-related conditions for an accurate diagnosis. UC and CD typically manifest in early adulthood, and the chronic nature of these conditions greatly impacts a patient's perception, body image, and quality of life. The inability to participate in social activities due to UC and CD impacts not only patients, but also those with whom they have close relationships.

    2010-06-01

    We present a case of hypermagnesemia accompanied by perforative peritonitis. A 79-year-old woman took magnesium citrate as part of the pretreatment on the day before a scheduled colonoscopy. She developed nausea and muscle weakness, and she was complaining of left abdominal pain. Consciousness gradually worsened and she developed shock. Intestinal obstruction was recognized on abdominal X-ray and computed tomography (CT), and peritonitis was suspected. An exploratory laparotomy was scheduled for diagnosis and treatment. In the operating room, arterial blood gas analysis showed metabolic acidosis and hypermagnesemia (Mg: 2.75 mmol/l, normal range: 0.1-1.5 mmol/l). On laparotomy, adhesion around the sigmoid colon and turbid ascites were recognized. But we could not detect the apparent region of perforation. Based on these findings and the presence of hypermagnesemia, we diagnosed that the shock was caused by peritonitis due to intestinal micro-perforation, and by hypermagnesemia due to absorption of laxative. We started to treat for metabolic acidosis, and to manage the hypermagnesemia by calcium hydrochloride administration and by continuous hemodiafiltration after the operation. On day 4 of the illness, the plasma Mg level was normalized. She was extubated on day 12, and discharged on day 84. This case with complicated clinical symptoms reaffirms the difficulty and importance of making a diagnosis quickly by collecting various data.

    Anterior cervical spine plating is a standard procedure for fixing unstable vertebral fractures. Following surgery, oesophageal perforation has an incidence of 0.25% and this is usually hours following surgery, due to over prominent screws or friction between the oesophagus and the plate. Instrumentation failure of these plates months or years following surgery is very rare but potentially life-threatening. We report a case of microcytic anaemia which was investigated by oesophagogastroduodenoscopy, and subsequently found that a screw from the anterior plate had lifted off and perforated the oesophagus. This is very rare, but emphasises an important lesson.

    Perforated plates are essential structural components of sonar acoustic domes of the submarines and underwater platforms. The sonar acoustic domes are considered as `water backed condition' for structural analysis. It is of utmost importance to study the structural response of sonar acoustic domes subjected to noncontact underwater explosion since it has wide scope in defence application. It is intended to investigate the free field pressure due to the underwater explosion and structural response of perforated plate using ANSYS LS-DYNA software for plastic explosive kirkee (PEK), Tri Nitro Toluene (TNT) and Composition 4 explosives. The free field pressure from TNT explosion is validated with the Cole's expression available for this explosive. The time history plots for free field pressure, displacement and principal stress are plotted for all the three explosives. The free field pressure is validated with Cole's formula and found 18 % variation for TNT and 14 % for PEK explosive.

    A 20-year-old man with nasal obstruction underwent septoplasty due to nasal septal deviation. Nasal packs were inserted at the end of surgery and removed 48 hours after surgery. Twenty-four hours after removal of nasal packs, there was necrosis in both sides of septal mucosa and in bilateral inferior turbinates. Nasal swab culture was performed from both nasal cavities. Enterobacter cloacae was isolated from samples. Two weeks after surgery, nasal septum perforation was unavoidable. To our knowledge, this is the first case in literature describing septal mucosal necrosis caused by this pathogen after septoplasty. Mucosal necrosis and perforation as septoplasty complications should be kept in mind, the result of causes both common and, as in the present case, unusual.

    Due to its importance and possible applications in visualization, tumor detection and pre-operative planning, automatic small bowel segmentation is essential for computer-aided diagnosis of small bowel pathology. However, segmenting the small bowel directly on CT scans is very difficult because of the low image contrast on CT scans and high tortuosity of the small bowel and its close proximity to other abdominal organs. Motivated by the intensity characteristics of abdominal CT images, the anatomic relationship between the mesenteric vasculature and the small bowel, and potential usefulness of the mesenteric vasculature for establishing the path of the small bowel, we propose a novel mesenteric vasculature map-guided method for small bowel segmentation on high-resolution CT angiography scans. The major mesenteric arteries are first segmented using a vessel tracing method based on multi-linear subspace vessel model and Bayesian inference. Second, multi-view, multi-scale vesselness enhancement filters are used to segment small vessels, and vessels directly or indirectly connecting to the superior mesenteric artery are classified as mesenteric vessels. Third, a mesenteric vasculature map is built by linking vessel bifurcation points, and the small bowel is segmented by employing the mesenteric vessel map and fuzzy connectness. The method was evaluated on 11 abdominal CT scans of patients suspected of having carcinoid tumors with manually labeled reference standard. The result, 82.5% volume overlap accuracy compared with the reference standard, shows it is feasible to segment the small bowel on CT scans using the mesenteric vasculature as a roadmap.

    We report a case of palatopharyngeal wall perforation during intubation with a GlideScope laryngoscope. The likely mechanism was advancing and rotating the endotracheal tube against a taut palatopharyngeal fold. This was missed during the initial laryngoscopy, because there is a potential blind-spot in the oropharynx when attention is focused on the GlideScope" monitor Fortunately, there were no sequelae other than minor bleeding and a mild sore throat and no surgical intervention was necessary. The use of unnecessary force during the endotracheal tube insertion, the use of too large a laryngoscope blade and the use of a rigid stylet could possibly also have been contributory factors to this complication.

    Thermal imaging detects infrared radiation from an object, producing a thermogram that can be interpreted as a surrogate marker for cutaneous blood flow. To date, high-resolution cameras typically cost tens of thousands of dollars. The FLIR ONE is a smartphone-compatible miniature thermal imaging camera that currently retails at under $200. In a proof-of-concept study, patients and healthy volunteers were assessed with thermal imaging for (1) detecting and mapping perforators, (2) defining perforasomes, and (3) monitoring free flaps. Preoperative, intraoperative, and postoperative thermograms can assist in the planning, execution, and monitoring of free flaps, and the FLIR ONE provides a low-cost adjunct that could be applied to other areas of burns and plastic surgery.

    POD Associates have revisited the issue of generic scaling laws able to adequately predict (within better than 20 percent) cratering in semi-infinite targets and perforations through finite thickness targets. The approach used was to apply physical logic for hydrodynamics in a consistent manner able to account for chunky-body impacts such that the only variables needed are those directly related to known material properties for both the impactor and target. The analyses were compared and verified versus CTH hydrodynamic code calculations and existing data. Comparisons with previous scaling laws were also performed to identify which (if any) were good for generic purposes. This paper is a short synopsis of the full report available through the NASA Langley Research Center, LDEF Science Office.

  10. 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

  11. Functional bowel symptoms and diet.

    It is well recognised that ingestion of food is a trigger for functional bowel symptoms, particularly those associated with irritable bowel syndrome (IBS). Patients often use manipulation of diet as a means of controlling symptoms. Despite description of multiple dietary methods, few have scientific backing or quality evidence of efficacy. One approach is to define how specific food components influence the pathophysiology of IBS and then rationally design dietary approaches. For example, short-chain poorly absorbed carbohydrates (fermentable oligo-, di- and mono-saccharides and polyols (FODMAP)) cause luminal distension, which is a major stimulus for the development of symptoms in patients with visceral hypersensitivity. By determining food content of FODMAP, a diet in which foods low in FODMAP are favoured over those high in FODMAP can be designed. Observational, comparative and randomised controlled treatment and rechallenge studies have shown that such an approach is efficacious in the majority of patients with IBS. The low FODMAP diet is now the primary dietary therapy for such patients. Similar approaches can be applied to other food components, including proteins (such as gluten), fats and natural bioactive food chemicals. Such approaches have suggestions of efficacy, but the evidence base remains underdeveloped. An additional and important consideration for any dietary therapy is its nutritional adequacy and potential adverse health effects. Dietary manipulation is now a key management strategy in patients with functional bowel symptoms. Future well-designed interventional studies will lead to refinement of dietary approaches taken and to a better understanding of their long-term safety.

    Context: Accidental root canal perforations are among the main complications of endodontic treatment. Aim: 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. Materials and Methods: 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. Results: The results showed lower volume and gap in the interface dentin/material in VOMG compared to the other groups (P < 0.05). Conclusion: The use of OM improved the quality of cervical perforations sealed with Vitremer, being indicated in clinical situations of iatrogenic cervical perforations. PMID:27099422

    Purpose To investigate the integration of subretinal implants containing full-depth perforations of various widths with rat and pig retina across weeks of implantation. Methods In transgenic P23H rhodopsin line 1 (TgP23H-1) rats and wild-type (WT) pigs, we examined four subretinal implant designs: solid inactive polymer arrays (IPA), IPAs with 5- or 10-μm wide perforations, and active bipolar photovoltaic arrays (bPVA) with 5-μm perforations. We surgically placed the implants into the subretinal space using an external approach in rats or a vitreoretinal approach in pigs. Implant placement in the subretinal space was verified with optical coherence tomography and retinal perfusion was characterized with fluorescein angiography. Rats were sacrificed 8 or 16 weeks post-implantation (wpi) and pigs 2, 4, or 8 wpi, and retinas evaluated at the light microscopic level. Results Regardless of implant design, retinas of both species showed normal vasculature. In TgP23H-1 retinas implanted with 10-μm perforated IPAs, inner nuclear layer (INL) cells migrated through the perforations by 8 wpi, resulting in significant INL thinning by 16 wpi. Additionally, these retinas showed greater pseudo-rosette formation and fibrosis compared with retinas with solid or 5-μm perforated IPAs. TgP23H-1 retinas with bPVAs showed similar INL migration to retinas with 5-μm perforated IPAs, with less fibrosis and rosette formation. WT pig retina with perforated IPAs maintained photoreceptors, showed no migration, and less pseudo-rosette formation, but more fibrosis compared with implanted TgP23H-1 rat retinas. Conclusions In retinas with photoreceptor degeneration, solid implants, or those with 5-μm perforations lead to the best biocompatibility. PMID:26290776

  14. A plausible explanation for male dominance in typhoid ileal perforation.

    PubMed

    Khan, Mohammad

    2012-01-01

    The phenomenon of consistent male dominance in typhoid ileal perforation (TIP) is not well understood. It cannot be explained on the basis of microbial virulence, Peyer's patch anatomy, ileal wall thickness, gastric acidity, host genetic factors, or sex-linked bias in hospital attendance. The cytokine response to an intestinal infection in males is predominantly proinflammatory as compared with that in females, presumably due to differences in the sex hormonal milieu. Sex hormone receptors have been detected on lymphocytes and macrophages, including on Peyer's patches, inflammation of which (probably similar to the Shwartzman reaction/Koch phenomenon) is the forerunner of TIP, and is not excluded from the regulatory effects of sex hormones. Hormonal control of host-pathogen interaction may override genetic control. Environmental exposure to Salmonella typhi may be more frequent in males, presumably due to sex-linked differences in hygiene practices and dining-out behavior. A plausible explanation of male dominance in TIP could include sex-linked differences in the degree of natural exposure of Peyer's patches to S. typhi. An alternative explanation may include sexual dimorphism in host inflammatory response patterns in Peyer's patches that have been induced by S. typhi. Both hypotheses are testable.

    Entero-cutaneous fistula resulting from a locally invasive large bowel carcinoma is a difficult surgical challenge. En-bloc resection of the involved organs and the entero-cutaneous fistula tract with a healthy tissue margin will result in a composite abdominal wall defect that requires closure. Reconstructive surgical options include primary closure, components separation and the use of local, regional or free flaps with or without prosthetic mesh. We report a case of an abdominal enterocutaneous fistula secondary to a locally invasive sigmoid carcinoma, which was reconstructed with a pedicled antero-lateral thigh perforator (ALT) flap. To our knowledge, this is the first case of a malignant entero-cutaneous fistula, which was reconstructed with an ALT flap.

    An 84-year-old lady with a history of chronic recurrent rectal prolapse, presented to accident and emergency with a significant portion of small bowel and mesentery protruding out of her anus. The small bowel was not contained within peritoneum, nor was this a pararectal herniation. On examination of the rectum, a longitudinal tear was found in the anterior rectal wall, through which the small bowel had prolapsed. Hours after reducing the small bowel back into the anus, it prolapsed a second time. Due to multiple co-morbidities, this patient was not fit for surgery. The defect was temporarily repaired on the ward and the patient treated with aggressive antibiotic therapy. The patient continued to deteriorate, became septic, acidotic, hypotensive and died a day later. PMID:22605863

    Diet has been speculated to be a factor in the pathogenesis of inflammatory bowel disease and may be an important factor in managing disease symptoms. Patients manipulate their diet in attempt to control symptoms, often leading to the adoption of inappropriately restrictive diets, which places them at risk for nutritional complications. Health professionals struggle to provide evidence-based nutrition guidance to patients due to an overall lack of uniformity or clarity amongst research studies. Well-designed diet studies are urgently needed to create an enhanced understanding of the role diet plays in the management of inflammatory bowel disease. The aim of this review is to summarize the current data available on dietary management of inflammatory bowel disease and to demonstrate that dietary modulation may be an important consideration in managing disease. By addressing the relevance of diet in inflammatory bowel disease, health professionals are able to better support patients and collaborate with dietitians to improve nutrition therapy.

    Duodenal ulcer is an uncommonly diagnosed entity in children. H. pylori infection, blood group 'O' or secondary to medications like non steroidal anti-inflammatory drugs (NSAID) and corticosteroids or physiological stress in burns, head injury and mucosal ischemia are implicated as risk factors for their causation. The diagnosis is usually overlooked because of vague and variable symptoms and remote index of suspicion accounted for their low incidence in children. Undiagnosed or mistreated perforations may carry high morbidity and mortality. We report a successfully treated 41/2 year old male child who presented with features of perforation peritonitis and was incidentally found to have a perforated duodenal ulcer.

    Hydrogels have been demonstrated to swell in response to a number of external stimuli including pH, CO2, glucose, and ionic strength making them useful for detection of metabolic analytes. To measure hydrogel swelling pressure, we have fabricated and tested novel perforated diaphragm piezoresistive pressure sensor arrays that couple the pressure sensing diaphragm with a perforated semi-permeable membrane. The 2×2 arrays measure approximately 3 × 5 mm2 and consist of four square sensing diaphragms with widths of 1.0, 1.25, and 1.5 mm used to measure full scale pressures of 50, 25, and 5 kPa, respectively. An optimized geometry of micro pores was etched in silicon diaphragm to allow analyte diffusion into the sensor cavity where the hydrogel material is located. The 14-step front side wafer process was carried out by a commercial foundry service (MSF, Frankfurt (Oder), Germany) and diaphragm pores were created using combination of potassium hydroxide (KOH) etching and deep reactive ion etching (DRIE). Sensor characterization was performed (without the use of hydrogels) using a custom bulge testing apparatus that simultaneously measured deflection, pressure, and electrical output. Test results are used to quantify the sensor sensitivity and demonstrate proof-of-concept. Simulations showed that the sensitivity was slightly improved for the perforated diaphragm designs while empirical electrical characterization showed that the perforated diaphragm sensors were slightly less sensitive than solid diaphragm sensors. This discrepancy is believed to be due to the influence of compressive stress found within passivation layers and poor etching uniformity. The new perforated diaphragm sensors were fully functional with sensitivities ranging from 23 to 252 μV/V-kPa (FSO= 5 to 80mV), and show a higher nonlinearity at elevated pressures than identical sensors with solid diaphragms. Sensors (1.5×1.5 mm2) with perforated diaphragms (pores=40 μm) have a nonlinearity of

    Gallstone ileus of the sigmoid colon is an important, though extremely rare, cause of large bowel obstruction. The gallstone often enters the large bowel through a fistula formation between the gallbladder and colon, and impacts at a point of narrowing, causing large bowel obstruction. We describe the case of an 80-year-old woman who presented with features of bowel obstruction. Multiplanar abdominal CT demonstrated a cholecystocolonic fistula in exquisite detail. The scan also showed obstruction of the colon due to a large gallstone impacted just proximal to a stricture in the sigmoid. Owing to inflammatory adhesions and a stricture from extensive diverticular disease, the gallstone could not be retrieved. This frail and elderly woman was treated with a loop colostomy to relieve bowel obstruction. The patient made an uneventful recovery.

    The incidence of inflammatory bowel diseases (IBD) - Crohn’s disease (CD) and ulcerative colitis (UC) - has been increasing on a global scale, and progressively, more gastroenterologists will be included in the diagnosis and treatment of IBD. Although IBD primarily affects the intestinal tract, extraintestinal manifestations of the disease are often apparent, including in the oral cavity, especially in CD. Specific oral manifestations in patients with CD are as follows: indurate mucosal tags, cobblestoning and mucogingivitis, deep linear ulcerations and lip swelling with vertical fissures. The most common non-specific manifestations, such as aphthous stomatitis and angular cheilitis, occur in both diseases, while pyostomatitis vegetans is more pronounced in patients with UC. Non-specific lesions in the oral cavity can also be the result of malnutrition and drugs. Malnutrition, followed by anemia and mineral and vitamin deficiency, affects the oral cavity and teeth. Furthermore, all of the drug classes that are applied to the treatment of inflammatory bowel diseases can lead to alterations in the oral cavity due to the direct toxic effects of the drugs on oral tissues, as well as indirect immunosuppressive effects with a risk of developing opportunistic infections or bone marrow suppression. There is a higher occurrence of malignant diseases in patients with IBD, which is related to the disease itself and to the IBD-related therapy with a possible oral pathology. Treatment of oral lesions includes treatment of the alterations in the oral cavity according to the etiology together with treatment of the primary intestinal disease, which requires adequate knowledge and a strong cooperation between gastroenterologists and specialists in oral medicine.

    Spontaneous perforation of a duodenal diverticulum is a rare but serious complication with significant mortality rates. Just over 100 cases have been reported in the world literature. One case of perforated duodenal diverticulum treated by simple closure is reported. An elderly female was admitted to our hospital with an acute abdomen. Computed tomography of the abdomen showed retroperitoneal air around the duodenum and right kidney. Laparotomy with a Kocher maneuver disclosed a perforated diverticulum in the second portion of the duodenum. Although diverticulectomy is the most common treatment, simple closure of the perforated duodenal diverticulum with drainage was performed to avoid injury to the distal common bile duct and ampulla of Vater, which were close to the diverticulum. The patient has fully recovered and has been asymptomatic with no signs of recurrence for 25 months.

    As with any dental treatment, procedural mishaps can occur during root canal therapy. One such occurrence is the perforation of a root or pulpal floor. After a perforation occurs, the goals are to "sterilize" (decontaminate) the site and then seal the perforation. The material most widely used in endodontics to seal perforations is mineral trioxide aggregate (MTA). MTA us extremely biocompatible, and it has been shown historically that osteoidlike material grows right into MTA. The technique of one-step apexification offers an alternative to draw-out cases with several medicament-changing appointments that often result in a failed attempt at root-end closure. With the favorable histologic response of MTA, this material is the best current choice for this procedure. Completion of these cases in an effective and efficient way allows for permanent restorations to be done in a more timely manner, prolonging the longevity of these teeth.

    The influence of a perforated extension region on pressures radiated from the end of a duct is studied numerically using CFD. Planar 2-D geometry is considered and particular attention is paid to the case of pressure disturbances radiated from railway tunnels in cut-and-cover regions. The mechanism that causes this behaviour is described and it is shown to have an important influence of the effectiveness of a perforated extension region. It is found that such regions can strongly reduce the pressures radiated from a duct outlet, but that this benefit is offset by pressures radiated directly from the holes along the perforated region itself. In the particular case of tunnel design, practical studies of wave transmission are usually based on 1-D, plane-wave, analyses. Accordingly, attention is paid to assessing the limitations of such approaches in the case of wave propagation along a perforated region.

    Gastrointestinal perforations, which need to be managed quickly, are associated with high morbidity and mortality. Treatments used to close these perforations range from surgery to endoscopic therapy. Nowadays, with the development of new devices and techniques, endoscopic therapy is becoming more popular. However, there are different indications and clinical efficacies between different methods, because of the diverse properties of endoscopic devices and techniques. Successful management also depends on other factors, such as the precise location of the perforation, its size and the length of time between the occurrence and diagnosis. In this study, we performed a comprehensive review of various devices and introduced the different techniques that are considered effective to treat gastrointestinal perforations. In addition, we focused on the different methods used to achieve successful closure, based on the literature and our clinical experiences. PMID:27672268

    2017-03-01

    Esophageal perforations can be spontaneous or iatrogenic. Although they are a rare occurrence, they are associated with a significant morbidity and mortality. Traditionally, management of esophageal perforation consisted of surgery. However, endoscopic management is now emerging as the primary treatment modality and is less invasive and morbid than surgery. Endoscopic modalities include through-the-scope clips (TTS), over-the-scope clips (OTSC), placement of covered stents, and suturing. Suturing can be used for primary closure of the perforation as well as anchoring of stents to prevent migration. Smaller defects (<2 cm) can be closed with clips (TTS or OTSC), whereas larger defects require a stent placement or suturing to achieve closure. If the perforation is associated with a mediastinal collection, drainage is mandatory and can be done via CT-guided percutaneous drainage, surgery, or endoscopic vacuum therapy.

    During the first step of cataract surgery, the lens capsule is perforated and a circular hole is created with a sharp instrument, a procedure called capsulorhexis. To develop automated systems that can assist ophthalmologists during capsulorhexis, the forces required must be quantified. This study investigates perforation forces of the central anterior lens capsule in porcine eyes, which are used as a conservative model for the human eye. A micro-mechanical characterisation method is presented that measures capsular bag perforation forces with a high precision positioning and high-resolution force sensing system. The force during perforation of the anterior lens capsule was measured with various sized needles and indentation speeds and is found to be 15-35mN. A bio-mechanical model is identified that describes an exponential correlation between indentation force and depth, indicating strain hardening behaviour of the porcine anterior lens capsule.

    Surgical closure of nasal septal perforations is one of the most challenging procedures in nasal surgery. Defects greater than 2 cm are especially difficult to repair with the traditional approaches due to the challenges of mobilizing enough mucosa to close big gaps, and avoiding airway stenosis in the process. We present a new technique to endoscopically close major septal perforations using bilateral Hadad-Bassagasteguy flaps. Four consecutive patients with septal perforations greater than 2 cm were operated at our institution. Bilateral Hadad-Bassagasteguy flaps were endoscopically raised, one of them above the defect and the other one below it, and rotated to partially cover the defect on each side. A deep temporalis fascia graft was sandwiched between the two flaps to provide a scaffold for schneiderian mucosa growth. Both flaps were covered with a silicone sheet for 3 weeks. A complete closure of the defect was accomplished in three of the four patients; partial closure was achieved in the other. Nasal crusting, epistaxis, and nasal breathing improved in all patients.

    Deep anterior lamellar keratoplasty (DALK) using Dr. Anwar's big bubble technique was performed for a patient with granular dystrophy. Intraoperatively, a perforation of the Descemet's membrane (DM) was noted inferonasally. Though the surgery was completed, the donor graft appeared to have an intact endothelium, which was inadvertently left behind by the surgeon. Intraoperatively, there was a perforation of inferonasal DM and surgery was completed by inadvertently placing a donor with an intact endothelium. Postoperatively the patient presented with a complete DM detachment and a resultant double anterior chamber (DAC). In spite of two attempts at an air tamponade on the first and fifth post operative days, the DAC still persisted. Surprisingly, during the 6(th) week follow up visit, there was a complete resolution of the DAC as well as total recovery of vision. This interesting case clearly exemplifies that, in spite of failed attempts at air tamponade, a DM detachment and a DAC due to DM perforation following a DALK procedure can resolve spontaneously with good visual outcome.

    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. PMID:27790119

    Patient: Female, 60 Final Diagnosis: Acute phlegmonous esophagogastritis complicated with hypopharyngeal abscess • esophageal perforation Symptoms: Fever • painful swallowing • chest pain Medication: — Clinical Procedure: Drainage • debridement • esophageal reconstruction Specialty: Surgery Objective: Rare disease Background: Acute phlegmonous esophagogastritis is a life-threatening disease that may be combined with serious complications. We present the classical radiological and endoscopic features and treatment strategy of a middle-aged female patient suffering from acute phlegmonous esophagogastritis complicated with hypopharyngeal abscess, esophageal perforation, mediastinitis, and empyema. Case Report: A 60-year-old Taiwanese female presented at our hospital due to fever, fatigue, painful swallowing, and vague chest pain for 5 days. She had a past history of uncontrolled type 2 diabetes mellitus. On physical examination, general weakness, chest pain, odynophagia, and a fever up to 38.9°C were found. Positive laboratory findings included leukocytosis (leukocyte count of 14.58×103/μL, neutrophils 76.8%) and serum glucose 348 mg/dL (HbA1c 11.3%). A diagnosis of acute phlegmonous esophagogastritis with hypopharyngeal abscess was made based on typical computed tomography image features and clinical signs of infection. The patient received empirical antibiotic therapy initially; however, esophageal perforation with mediastinitis and empyema developed after admission. Emergency surgery with drainage and debridement was performed and antibiotics were administered. She was discharged in a stable condition on the 56th day of hospitalization. Six months later, a delayed esophageal reconstruction was performed. The patient has performed well for 9 months to date since the initial diagnosis. Conclusions: Acute phlegmonous esophagogastritis complicated with hypopharyngeal abscess and esophageal perforation is extremely rare, and requires immediate medical

    Pulsed underwater electrical discharges have been used in the past to generate pressures of the order of several tens of kilobars, for applications such as rock fragmentation and metallic jet production. Preliminary results for a metallic jet system have been reported earlier. A modified design for a metallic jet production system is reported here. With this arrangement, we are able to perforate 11 mm thick aluminium sheet. Such a system, at higher energy levels, could be used for oil and gas well perforation.

    Foreign body ingestion is a common problem in children, but magnet ingestion is relatively rare. However, when it occurs, it tends to have a high rate of complications. This is a case report of a 3-year-old child who swallowed multiple magnetic toys, subsequently developing jejunoileal perforation and volvulus. This case report indicates that it is best to surgically remove multiple ingested magnets without delay to avoid intestinal perforation, fistula, and other complications such as volvulus.

    Abstract Colorectal tumor perforation is a life-threatening complication of this disease. However, little is known about the anatomopathological factors or pathophysiologic mechanisms involved. Pathological and immunohistochemical analysis of factors related with tumoral neo-angiogenesis, which could influence tumor perforation are assessed in this study. A retrospective study of patients with perforated colon tumors (Group P) and T4a nonperforated (controls) was conducted between 2001 and 2010. Histological variables (differentiation, vascular invasion, and location) and immunohistochemical (CD31, Growth Endothelial Vascular Factor (VEGF) and p53) related with tumor angiogenesis were analyzed. Of 2189 patients, 100 (4.56%) met the inclusion criteria. Of these, 49 patients had nonperforated (2.23%) and 51 had perforated tumors (2.32%). The P group had lower number of right-sided tumors (7/51, 13.7%) compared with controls (13/49, 36.7%) (P = .01). The high-grade tumors (undifferentiated) represented only 3.9% of the perforated tumors; the remaining 96.1% were well differentiated (P = .01). No differences between groups in the frequency of TP53 mutation or VEGF and CD31 expression were found. In the P group, only 2 (3.9%) had vascular invasion (P = .01). Of the 12 tumors with vascular invasion, only 2 were perforated (16.6%). The median number of metastatic lymph-nodes in P Group was 0 versus 3 in controls (Z = −4.2; P < .01). Pathological analysis of variables that indirectly measure the presence of tumor angiogenesis (differentiation, vascular invasion, and the number of metastatic lymph nodes) shows a relationship between this and the perforation, location, and tumor differentiation. We could not directly validate our hypothesis, by immunohistochemistry of TP53, VEGF, and CD31, that perforated tumors exhibit less angiogenesis. PMID:25881846

    Abstract Systemic Epstein–Barr virus (EBV)-positive T-cell lymphoproliferative disorders (LPDs) of childhood is a highly aggressive EBV-positive T/natural killer (NK)-cell LPD, which emerges in the background of chronic active EBV infection (CAEBV) or shortly after primary acute EBV infection. The clinical presentations of CAEBV are varied; patients with atypical manifestations are easily misdiagnosed. We described a 14-year-old boy suffering from digestive disorders and intermittent fever for 1 year and 9 months, whose conditions worsened and skin lesions occurred 2 months before hospitalization. He was diagnosed as inflammatory bowel diseases (IBD) and treated accordingly. His other clinical features, hepatosplenomegaly, lymphadenopathy, anemia, hypoalbuminemia, and elevated inflammatory marks, were found in hospitalization. The boy suffered from repeatedly spontaneous intestinal perforations shortly after hospitalization and died of intestinal hemorrhea. The pathological results of intestine and skin both showed EBV-positive T/NK-cell LPD (lymphoma stage). There are rare studies reporting gastrointestinal perforations in EBV-positive T/NK-cell LPD, let alone repeatedly spontaneous perforations. Based on the clinical features and pathological results of this patient, the disease progressed from CAEBV (T-cell type) to systemic EBV-positive T-cell LPD of childhood (lymphoma). Not all the patients with CAEBV could have unusual patterns of anti-EBV antibodies. However, the presence of high EBV loads (EBV-encoded early small ribonucleic acid (RNA) (EBER) in affected tissues and/or EBV deoxyribonucleic acid (DNA) in peripheral blood) is essential for diagnosing CAEBV. Maybe because of his less common clinical features for CAEBV and negative anti-EBV antibodies, the boy was not diagnosed correctly. We should have emphasized the test for EBER or EBV-DNA. Meanwhile, for the IBD patients whose manifestations were not typical, and whose conditions were not improved by

  1. Irritable bowel syndrome and inflammatory bowel disease: interrelated diseases?

    In the past inflammatory bowel disease (IBD), celiac disease and irritable bowel syndrome (IBS) were regarded as completely separate disorders. Now, with the description of inflammation, albeit low-grade, in IBS, and of symptom overlap between IBS and celiac disease, this contention has come under question. Is there true overlap between these disorders? Despite the limitations of available data one cannot but be struck by some areas of apparent convergence: IBD and celiac disease in remission, lymphocytic colitis and microscopic inflammation in IBS, in general, and, especially, in the post-infectious IBS category. The convergence between latent celiac disease and sub-clinical IBD, on the one hand, and IBS, on the other, appears, based on available evidence, to be somewhat spurious and may largely relate to misdiagnosis, a phenomenon which may also explain the apparent evolution of IBS into IBD in some studies. Similarities between IBS and lymphocytic colitis are more striking and less readily dismissed; as for IBS, well documented instances of progression of lymphocytic colitis to full-blown IBD are infrequent, suggesting a true separation between this disorder and classical IBD. Do IBS and lymphocytic colitis represent different responses to similar triggers? Will some of the 'inflamed' IBS subgroup be reclassified as part of the spectrum of lymphocytic colitis in the future? Will inflammation emerge as a common underlying factor in the pathogenesis of IBS? The answer to these and many questions must await further study of this fascinating area.

    BACKGROUND Reconstruction of soft tissue defects in the lower third of the leg remains challenging. Anatomical constraints limit the local options available for complex defects especially lower third of leg. Local flaps based on perforator vessels are raising interest in reconstructive surgery of the limbs. We present our experience with perforator flaps for reconstruction of soft tissue defects in the lower limb. METHODS The study was carried prospectively and 23 patients with lower limb defects treated with various perforator flaps (both elective as well as emergency) were included in the study. A hand-held ultrasound Doppler was used preoperatively and intraoperatively to detect the perforator vessels. RESULTS Out of 23 patients, we witnessed partial flap loss in 1 and distal flap necrosis in 3 patients. Four patients had minor complications which included infection, wound dehiscence and congestion of flap. CONCLUSION Perforator flaps may represent a good alternative to the free flaps in the areas were other local reconstructive procedures are not possible. This is a versatile technique and with decreased donor site morbidity limited to a single body area. There is a specific like to like soft tissue replacement leading to a better cosmetic and reconstructive outcome. The main drawback of the perforator flaps however is the higher risk of venous congestion. PMID:28289617

    Patients with inflammatory bowel disease (IBD) are increasingly becoming interested in nonpharmacologic approaches to managing their disease. One of the most frequently asked questions of IBD patients is what they should eat. The role of diet has become very important in the prevention and treatment of IBD. Although there is a general lack of rigorous scientific evidence that demonstrates which diet is best for certain patients, several diets-such as the low-fermentable oligosaccharide, disaccharide, monosaccharide, and polyol diet; the specific carbohydrate diet; the anti-inflammatory diet; and the Paleolithic diet-have become popular. This article discusses the diets commonly recommended to IBD patients and reviews the supporting data.

    The role of alcohol in causing or aggravating the pathogenesis of inflammatory bowel disease is unclear. For finding a conclusive answer for this valuable question we conducted this review. Only two studies were identified that successfully fulfilled our inclusive criteria. Usual consumption of alcohol reduced the risk compared with less frequent use (odds ratio = 0.57, 95%CI: 0.37-0.86). Light alcoholic drinking has protective effects against development of ulcerative colitis. But this inverse association disappeared when smoking was included.

    The past few years have seen a great expansion of our understanding of the pathophysiology of inflammatory bowel disease (IBD). Much of the progress has been on the genetic basis of disease as well as the role of microbiota. These findings have magnified the role of the environmental component of this rather complex process. Recent advances have emanated from more in-depth, comprehensive, and at times nontraditional inquiry into the potential role of diet through its anti-inflammatory properties and modulation of microbiota. This concise review focuses on the novel aspects of research related to the potential role of diet in IBD.

  6. Typhoid intestinal perforation in developing countries: Still unavoidable deaths?

    PubMed Central

    2017-01-01

    Typhoid fever is a public health challenge mostly concentrated in impoverished, overcrowded areas of the developing world, with lack of safe drinking and sanitation. The most serious complication is typhoid intestinal perforation (TIP), observed in 0.8% to 39%, with a striking rate difference between high-income and low-middle-income countries. Although the mortality rate consequent to TIP in resource-poor countries is improved in the last decades, it is still fluctuating from 5% to 80%, due to surgical- and not surgical-related constraints. Huge economic costs and long timelines are required to provide a short- to middle-term solution to the lack of safe water and sanitation. Inherent limitations of the currently available diagnostic tools may lead to under-evaluation as well as over-evaluation of the disease, with consequent delayed treatment or inappropriate, excessive antibiotic use, hence increasing the likelihood of bacterial resistance. There is a need for immunization programs in populations at greatest risk, especially in sub-Saharan Africa. Uniform surgical strategies and guidelines, on the basis of sound or prospective surgical studies and adapted to the local realities, are still lacking. Major drawbacks of the surgical treatment are the frequent delays to surgery, either for late diagnosis or for difficult transports, and the unavailable appropriate intensive care units in most peripheral facilities. As a consequence, poor patient’s conditions at presentation, severe peritoneal contamination and unsuitable postoperative care are the foremost determinant of surgical morbidity and mortality.

    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.

    This paper presents a case study in which the finite element model for a curved circular plate is calibrated to reproduce both the linear and nonlinear dynamic response measured from two nominally identical samples. The linear dynamic response is described with the linear natural frequencies and mode shapes identified with a roving hammer test. Due to the uncertainty in the stiffness characteristics from the manufactured perforations, the linear natural frequencies are used to update the effective modulus of elasticity of the full order finite element model (FEM). The nonlinear dynamic response is described with nonlinear normal modes (NNMs) measured using force appropriation and high speed 3D digital image correlation (3D-DIC). The measured NNMs are used to update the boundary conditions of the full order FEM through comparison with NNMs calculated from a nonlinear reduced order model (NLROM). This comparison revealed that the nonlinear behavior could not be captured without accounting for the small curvature of the plate from manufacturing as confirmed in literature. So, 3D-DIC was also used to identify the initial static curvature of each plate and the resulting curvature was included in the full order FEM. The updated models are then used to understand how the stress distribution changes at large response amplitudes providing a possible explanation of failures observed during testing.

    The clinical features of ulcerative colitis and Crohn's disease are similar to those of infections of the bowel, although their cause is uncertain. Many bacteria that cause intestinal diseases adhere to the gut mucosa, and adhesion of pathogenic Escherichia coli is resistant to D-mannose. The adhesive properties of isolates of E coli were assessed by assay of adhesion to buccal epithelial cells with mannose added. The isolates were obtained from patients with inflammatory bowel diseases (50 with a relapse of ulcerative colitis, nine with ulcerative colitis in remission, 13 with Crohn's disease, and 11 with infectious diarrhoea not due to E coli) and 22 controls. The median index of adhesion to buccal epithelial cells (the proportion of cells with more than 50 adherent bacteria) for E coli from patients with ulcerative colitis in relapse was significantly higher (43%) than that for controls (5%) and patients with infectious diarrhoea (14%). The index was not significantly different among isolates from patients with ulcerative colitis in relapse, Crohn's disease (53%), and ulcerative colitis in remission (30%). If an index of adhesion of greater than 25% is taken as indicating an adhesive strain 86% of isolates of E coli from patients with inflammatory bowel disease were adhesive compared with 27% from patients with infective diarrhoea and none from controls. The adhesive properties of the isolates from patients with inflammatory bowel disease were similar to those of pathogenic intestinal E coli, raising the possibility that they may have a role in the pathogenesis of the condition; the smaller proportion of adhesive isolates in patients with infective diarrhoea due to other bacteria suggests that the organism may be of primary importance rather than arising secondarily.

    Irritable bowel syndrome is a complex disorder whose pathophysiology involves alterations in the enteric microbiota, visceral hypersensitivity, gut immune/barrier function, hypothalamic-pituitary-adrenal axis regulation, neurotransmitters, stress response, psychological factors, and more. The importance of diet in the management of irritable bowel syndrome has taken center stage in recent times as the literature validates the relationship of certain foods with the provocation of symptoms. Likewise, a number of elimination dietary programs have been successful in alleviating irritable bowel syndrome symptoms. Knowledge of the dietary management strategies for irritable bowel syndrome will help guide nutritionists and healthcare practitioners to deliver optimal outcomes. This tutorial reviews the nutrition management strategies for irritable bowel syndrome.

    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 (P<.001). Multivariate models demonstrated male gender and warfarin use negatively predicted thrombosis of IPVs (P=.03, P=.01). Multivariate model for ulcer 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

    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.

    Completion of cased and cemented wells by shaped charge perforation causes its own damage to the formation, potentially reducing well productivity. In practice it is found that underbalance conditions clean up the damaged zone to some extent, however, the mechanisms of these processes are poorly understood. Most hydrocodes typically used to simulate rock response to shaped charge penetration do not provide permeability estimates. Furthermore, the time scales for formation clean up are potentially much longer than the period of jet penetration. We have developed a simple, yet accurate model for the evolution of porosity and permeability which can easily be incorporated into existing hydrocodes using information from the history of each cell. In addition, we have developed a code that efficiently simulates fines migration during the post-shot surge period using initial conditions taken directly from hydrocode simulations of jet penetration. Results from a one-dimensional model simulation are in excellent agreement with measured permeability distributions. We also present two-dimensional numerical results which qualitatively reproduce experimentally obtained permeability maps for different values of underbalance. Although initial results have been promising, further comparison with experiment is essential to tune the coupling between the hydrocode and fines migration simulator. Currently the permeability model is most appropriate for high permeability sandstones (such as Berea), but with little effort, the model can be extended to other rock types, given sufficient experimental data.

    Current oil well perforation techniques use low- to medium-velocity gun launchers for completing wells in soft rock. Shaped-charge jets are normally used in harder, more competent rock. A device to create a much higher velocity projectile was designed. This launcher will provide an alternative technique to be used when the conventional devices do not yield the maximum well performance. It is an adaptation of the axial cavity in a high explosive (HE) annulus design, with the axial cavity being filled with a low density foam material. Two configurations were tested; both had an HE annulus filled with organic foam, one had a projectile. Comparison of the two shots was made. A time sequence of Image Intensifier Camera photographs and sequential, orthogonal flash x-ray radiographs provided information on the propagation of the foam fragments, the first shock wave disturbance, the projectile motion and deformation, and the direct shock wave transmission from the main HE charge. DYNA2D calculations were made to assist in the experimental interpretation. 25 refs., 9 figs.

All subjects received a gallon of polyethylene glycol as bowel preparation regimen. After colonoscopy the endoscopists determined quality of bowel preparation using BBPS. Segmental scores were combined to calculate composite BBPS. Site and size of the polyps detected was recorded. Pathology reports were reviewed to determine advanced adenoma detection rates (AADR). Segmental AADR’s were calculated and categorized based on the segmental BBPS to determine the differential impact of bowel prep on AADR. RESULTS: Three hundred and sixty subjects were enrolled in the study with a mean age of 59.2 years, 36.3% males and 63.8% females. Four subjects with incomplete colonoscopy due BBPS of 0 in any segment were excluded. Based on composite BBPS subjects were divided into 3 groups; Group-0 (poor bowel prep, BBPS 0-3) n = 26 (7.3%), Group-1 (Suboptimal bowel prep, BBPS 4-6) n = 121 (34%) and Group-2 (Adequate bowel prep, BBPS 7-9) n = 209 (58.7%). AADR showed a linear trend through Group-1 to 3; with an AADR of 3.8%, 14.8% and 16.7% respectively. Also seen was a linear increasing trend in segmental AADR with improvement in segmental BBPS. There was statistical significant difference between AADR among Group 0 and 2 (3.8% vs 16.7%, P < 0.05), Group 1 and 2 (14.8% vs 16.7%, P < 0.05) and Group 0 and 1 (3.8% vs 14.8%, P < 0.05). χ2 method was used to compute P value for determining statistical significance. CONCLUSION: Segmental AADRs correlate with segmental BBPS. It is thus valuable to report segmental BBPS in colonoscopy reports in clinical practice. PMID:25852286

    Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD) and is frequently overlooked as a complication. Patients with IBD are commonly found to have iron deficiency anemia (IDA) secondary to chronic blood loss, and impaired iron absorption due to tissue inflammation. Patients with iron deficiency may not always manifest with signs and symptoms; so, hemoglobin levels in patients with IBD must be regularly monitored for earlier detection of anemia. IDA in IBD is associated with poor quality of life, necessitating prompt diagnosis and appropriate treatment. IDA is often associated with inflammation in patients with IBD. Thus, commonly used laboratory parameters are inadequate to diagnose IDA, and newer iron indices, such as reticulocyte hemoglobin content or percentage of hypochromic red cells or zinc protoporphyrin, are required to differentiate IDA from anemia of chronic disease. Oral iron preparations are available and are used in patients with mild disease activity. These preparations are inexpensive and convenient, but can produce gastrointestinal side effects, such as abdominal pain and diarrhea, that limit their use and patient compliance. These preparations are partly absorbed due to inflammation. Non-absorbed iron can be toxic and worsen IBD disease activity. Although cost-effective intravenous iron formulations are widely available and have improved safety profiles, physicians are reluctant to use them. We present a review of the pathophysiologic mechanisms of IDA in IBD, improved diagnostic and therapeutic strategies, efficacy, and safety of iron replacement in IBD. PMID:26301120

    Perforating technology has undergone significant advances during the last decade. Tubing conveyed perforating (TCP), underbalanced perforating, high shot density guns, better shaped charges, and improved gun systems are some of the developments that have contributed to safer operations and improved productivity of the perforated completions. A recent development, described in this paper, is a perforating tool that makes real-time downhole measurements during a perforating run and has the capability of selectively firing a number of guns at different depths or times. These measurements include pressure, flow rate, temperature, GR, CCL, and cable tension. The simultaneous downhole measurements, in addition to providing better control of the perforating process, can in a single trip provide a production log, conventional well tests before and after perforating, and a fill-up or slug test soon after perforating for underbalanced conditions.

    Objectives: To examine the late period retinal and choroidal alterations in the posterior pole of eyes that underwent primary suturing due to traumatic corneal perforation. Materials and Methods: This cross-sectional case series included 21 eyes of 21 patients. The fellow eyes served as the control group. Macular thickness, peripapillary retinal nerve fiber layer (RNFL) thickness, choroidal thickness, and retinal vessel caliber measurements were performed by spectral-domain optical coherence tomography (SD-OCT). Results: The mean RNFL thickness was 102.1±10.9 µm in the perforated eyes and 99.5±8.5 µm in the fellow eyes (p=0.29). The mean central macular thickness was 300.1±25.6 µm in the perforated eyes and 295.6±23.2 µm in the fellow eyes (p=0.62). The choroidal thickness and retinal vascular caliber measurements were also similar between the groups (p>0.05). Conclusion: Operated traumatic corneal perforations do not cause significant posterior pole retinal and choroidal SD-OCT thickness changes in the late postoperative period. PMID:27800241

    Introduction Small bowel obstruction in a virgin abdomen is an uncommon surgical condition. While malignancy, inflammatory bowel disease and foreign body are the main reported causes, undigested food bezoar causing bowel obstruction is a rare entity. We report a case of small bowel obstruction secondary to dried preserved apple having re-expanded within the gastrointestinal tract. Presentation of case A 69 year old male presented with severe abdominal distension, generalized abdominal tenderness and obstipation for 1 week. Small bowel obstruction (SBO) was confirmed on plain abdominal X-ray and CT imaging. An emergency explorative laparatomy identified a sausage-shaped intra-luminal foreign body obstructing the distal ileum. An enterotomy was performed which revealed a rehydrated, donut-shaped piece of dried apple. Discussion Swallowed items that pass through the pylorus rarely cause obstruction as they are usually small enough to pass through the rest of the bowel without difficulty. We postulate that in our patient that the dried apple was originally small enough to pass through the pylorus. However during small bowel, its’ highly absorbable nature resulted in an increase in size that prevented its’ passage through the ileocecal valve. A simple in-vitro experiment discovered that dried apple has a potential to reabsorb fluid and expand up to 35% of its initial size within 72 h. Conclusion This report illustrates the potential for dried food substances to cause intra-luminal SBO after significant expansion with rehydration. PMID:25841159

  20. Surgical management of short bowel syndrome.

    2014-05-01

    For patients with short bowel syndrome (SBS), surgery can play an important role in preventing, mitigating, and, in some cases, reversing intestinal failure (IF). During intestinal resection, bowel length should be conserved to the fullest extent possible to avoid dependence on parenteral nutrition (PN). Bowel salvage may be improved by initially preserving tissue of questionable viability and later reevaluating during "second-look" procedures. Once the patient is stabilized, ostomy reversal and recruitment of distal unused bowel should be prioritized whenever feasible. Following progression to IF, surgical management of SBS depends on the symptoms and anatomical characteristics of the individual patient. For carefully selected patients with rapid intestinal transit and dilated bowel, longitudinal intestinal lengthening and tailoring (LILT) and serial transverse enteroplasty (STEP) procedures may provide benefit. Outcomes following STEP and LILT are generally similar, and the choice between these procedures may rest on surgeon preference. For patients with rapid intestinal transit in the absence of bowel dilation, segmental reversal of the small bowel may reduce PN requirements. Intestinal transplantation is the standard of care for patients in whom intestinal rehabilitation attempts have failed and who are at risk of life-threatening complications of PN. Because patients awaiting isolated intestine transplant show increased survival compared with patients awaiting combined intestine-liver transplant, early referral of appropriate patients, before the development of advanced liver disease, is critical to enhancing patient outcomes.

    Inflammatory bowel disease (IBD) is an inflammation of the lining of the human bowel and a major health issue in Europe. IBD carries with it significant morbidity from toxic treatment, surgery and a risk of developing bowel cancer. Thus there is a need for early identification of the disease using non-invasive tests. Present diagnostic techniques are based around invasive tests (i.e. endoscopy) and laboratory culture; the latter is limited as only 50% of the gut bacteria can be identified. Here we explore the use of an e-nose as a tool to detect and identify two IBDs (i.e. Crohn's disease (CD) & Ulcerative Colitis (UC)) based on headspace analysis from urine samples. We believe that the gut bacterial flora is altered by disease (due to fermentation) that in-turn modulates the gas composition within urine samples. 24 samples (9 CD, 6 UC, 9 controls) were analysed with an in-house e-nose and an Owlstone IMS instrument. Data analysis was performed using linear discriminant analysis (LDA and principal components analysis (PCA). Using the e-nose, LDA separates both disease groups and control, whilst PCA shows a small overlap of classes. The IMS data are more complex but shows some disease/control separation. We are presently collecting further samples for a larger study using more advanced data processing methods.

    In the present experimental study, investigations have been carried out to evaluate the performance of the new control technique of jet screech with different perforated flat reflectors. Mainly two types of porous flat reflectors had been used in the experiment. One reflector (reflector-V) designed for placing the reflector surface vertical to the jet axis, when, another type of reflector (reflector-H) designed for placing the reflecting surface horizontal to the jet axis. In both cases the reflectors had been placed at the nozzle (base tube with uniform cross-sectional area) exit. The diameter of the reflector-V was 15D when the diameter of the reflector-H was 10D. The porous area of the reflector-V was 6D and 4.5D for reflector-H where D indicated the diameter of the nozzle exit. The placement of the reflector at the exit of the nozzle reduces the sound pressure at the nozzle exit. Thus the muted sound can not excite the unstable disturbance at the nozzle exit and the loop of the feedback mechanism disappeared, finally, the generation of jet screech be cancelled. The suction space located at the back side of the porous surface of the reflector-V improves the efficiency of the screech control technique. However, in the case of reflector-H, the receptivity process of feedback loop had been controlled by reducing the disturbances at the effective shock fronts as well as at the nozzle exit. The performance of the proposed method was verified with a flat reflector concept and good performance in jet screech suppression has been confirmed in the case of porous reflector.

    Bowel-associated dermatosis-arthritis syndrome (BADAS) is a neutrophilic dermatosis, characterized by the occurrence of arthritis and skin lesions related to bowel disease with or without bowel bypass. We report an unusual case of BADAS in a 15-year-old white male with congenital aganglionosis of the colon and hypoganglionosis of the small intestine and multiple bowel surgeries in childhood complicated by short bowel syndrome. He presented with recurrent peripheral polyarthritis, tenosynovitis, and painful erythematous subcutaneous nodules located on the dorsolateral regions of the legs and on the dorsa of the feet. Histological examination disclosed a neutrophilic dermatosis confirming the diagnosis of BADAS.Although an uncommon disease, especially at pediatric age, it is important to evoke the diagnosis of BADAS in children and adolescents with bowel disease, because treatment options and prognosis are distinct from other rheumatologic conditions.

    The small bowel is essential to sustain alimentation and small bowel Crohn's disease (CD) may severely limit its function. Small bowel imaging is a crucial element in diagnosing small bowel CD, and treatment control with imaging is increasingly used to optimize the patients outcome. Thereby, capsule endoscopy, Balloon-assisted enteroscopy, and Magnetic resonance imaging have become key players to manage CD patients. In this review, role of small bowel imaging is detailed discussed for use in diagnosing and managing Crohn's disease patients.

    Short bowel syndrome (SBS) is a reduction in functioning bowel length which is most often a result of surgical resection. Risk factors in the neonatal period include necrotising enterocolitis, small bowel atresia and gastroschisis. With increasing survival of preterm infants there is an increase in incidence. Management is dependent on the use of parenteral nutrition to maintain fluid and electrolyte homeostasis and promote growth and development with the longer term aim being to promote intestinal adaptation to achieve partial or complete enteral autonomy. In this review we discuss the incidence, aetiology, pathophysiology, medical and surgical treatments and outcome.

    In terms of electrochemical behaviour, a transparent conductive oxide (TCO)-less dye-sensitized solar cell (DSSC) with two metal foils was compared with those of a metal foil-based DSSC with a TCO-coated substrate. By virtue of electrochemical impedance spectroscopy, intensity modulated photocurrent spectroscopy, intensity modulated photovoltage spectroscopy, open-circuit voltage decay, and photocurrent transient measurements, it was clearly confirmed that the limited performance of the TCO-less DSSC was caused by the restricted transport of ion species in the electrolyte due to the perforation patterned metal foil.

    Summary: The management of recurrent rectovaginal fistula after obstetric injury and cryptoglandular sepsis is considered a major surgical challenge. The fistula poses a significant negative psychosocial and sexual morbidity. In addition, the poor quality of local tissues due to previous attempts at surgical repair adds to this challenge. There are few data regarding the management of persistent or recurrent fistula in the literature; however, several studies reported high failure rates after 2 or more procedures. We present 4 cases managed successfully in a multidisciplinary approach involving fistulectomy and immediate reconstruction with an internal pudendal artery perforator island flap. PMID:27622109

    Species of the genus Bacillus are a common laboratory contaminant, therefore, isolation of these organisms from blood cultures does not always indicate infection. In fact, except for Bacillus anthracis and Bacillus cereus, most species of the genus Bacillus are not considered human pathogens, especially in immunocompetent individuals. Here, we report an unusual presentation of bacteraemia and mediastinitis due to co-infection with Bacillus subtilis and Bacillus licheniformis, which were identified by 16S RNA gene sequencing, in a patient with an oesophageal perforation.

    Purpose An intestinal perforation is a rare condition, but has a high mortality rate, even after immediate surgical intervention. The clinical predictors of postoperative morbidity and mortality are still not well established, so this study attempted to identify risk factors for postoperative morbidity and mortality after surgery for an intestinal perforation. Methods We retrospectively analyzed the cases of 117 patients who underwent surgery for an intestinal perforation at a single institution in Korea from November 2008 to June 2014. Factors related with postoperative mortality at 1 month and other postoperative complications were investigated. Results The mean age of enrolled patients was 66.0 ± 15.8 years and 66% of the patients were male. Fifteen patients (13%) died within 1 month after surgical treatment. Univariate analysis indicated that patient-related factors associated with mortality were low systolic and diastolic blood pressure, low serum albumin, low serum protein, low total cholesterol, and high blood urea nitrogen; the surgery-related factor associated with mortality was feculent ascites. Multivariate analysis using a logistic regression indicated that low systolic blood pressure and feculent ascites independently increased the risk for mortality; postoperative complications were more likely in both females and those with low estimated glomerular filtration rates and elevated serum C-reactive protein levels. Conclusion Various factors were associated with postoperative clinical outcomes of patients with an intestinal perforation. Morbidity and mortality following an intestinal perforation were greater in patients with unstable initial vital signs, poor nutritional status, and feculent ascites. PMID:28119865

    The articular disc plays an important role as a stress absorber in joint movement, resulting in stress reduction and redistribution in the temporomandibular joint (TMJ). The flow of synovial fluid in the TMJ may follow a regular pattern during movement of the jaw. We hypothesised that the regular pattern is disrupted when the TMJ disc is perforated. By computed tomography arthrography, we studied the upper TMJ compartment in patients with small disc perforation during jaw opening-closing at positions from 0 to 3 cm. Finite element fluid dynamic modelling was accomplished to analyse the pattern of fluid flow and pressure distribution during the movements. The results showed that the fluid flow in the upper compartment generally formed an anticlockwise circulation but with local vortexes with the jaw opening up to 2 cm. However, when the jaw opening-closing reached 3 cm, an abnormal flow field and the fluid pressure change associated with the perforation may increase the risk of perforation expansion or rupture and is unfavourable for self-repair of the perforated disc.

    The flat plates, perforated by a large number of holes are widely used in the engineering, especially in the component of the process equipment. Strength calculations and experimental methods used in the actual literature for study perforated plates, do not present the problem in all its complexity for stress distribution and displacements. Research and doctoral theses in last decades, with methods characteristic of the respective periods were engaged either perforated plates considered infinite and requested the median plane or rarely, plate loaded normal to the median plane, with a small number of holes. In this work the stress distribution and displacement is presented for a circular plate perforated by 96 holes arranged in a grid of squares, simply supported on the outline and loaded through a central concentrated force or by uniformly distributed load. It conducted a numerical analysis by finite element method (FEM) with a proper meshing of the plate and an experimental study by holographic interferometry. Holographic interferometry method permits to measure, with high accuracy, extremely small displacements and comparing the results with those obtained by FEM becomes sustainable. Supplementary, an analysis of a non-perforated plate with the same dimensions and stiffness, similar loaded, was performed, determining the coefficient of stress concentration for a particular arrangement of holes.

    Duodenal ulcer perforation in pediatric age group is an uncommon entity; hence, it is not usually considered in the differential diagnosis of acute abdomen in these patients. It is important for the emergency physician to consider perforated peptic ulcer in the differential diagnosis of children presenting with acute abdominal pain, gastrointestinal bleeding, or shock. We report a 6½-year-old male child with thalassemia major who presented to emergency room with an acute abdomen and shock, who was subsequently found to have a perforated duodenal ulcer, probably related to use of oral chelating agent, deferasirox. Although, gastrointestinal symptoms like nausea, vomiting, and abdominal pain has been mentioned as infrequent adverse event in the scientific product information of deferasirox, in our current knowledge this is the first case report of perforated duodenal ulcer after oral deferasirox. The severity of this event justifies the reporting of this case. This patient had an atypical presentation in that there were no signs or symptoms of peptic ulcer disease before perforation and shock he was successfully managed with open surgery after initial resuscitation and stabilization of his general condition.

    Porous cell honeycomb liners for aircraft engine nacelles offer the possibility of exploiting extended reaction effects to improve liner attenuation bandwidth as generally attributed to the performance of bulk absorbers. This paper describes an analytical procedure, starting with an impedance prediction model for a single perforated plate, to estimate the bulk-absorber parameters for a cascade of such perforates - a first step to modeling a porous wall honeycomb structure. The objective is to build confidence in a lumped element impedance model, when applied to a uniformly-spaced set of porous plates to predict its .bulk. absorber properties. The model is based upon a modified version of the two-parameter flow resistance model of the form A + BV(sub inc), where A and B are physics-based, semi-empirical parameters that are adjusted to provide an optimum fit to a composite dataset from three plate porosities of 2.5, 5 and 10%. The composite dataset is achieved by reformulating the two-parameter flow resistance model into a .reduced pressure drop coefficient. dependency on perforate hole Reynolds number. The resulting impedance model is employed to calculate surface impedance spectra for N and 2N-layer perforate cascades. The well-known two-thickness method for experimental determination of bulk-absorber parameters is then applied to these .synthesized. data sets to predict the characteristic impedance and propagation constant for the perforate cascades. These results are then compared with experimental results reported in a companion paper.

The etiopathogenesis of IBS may be multifactorial, as is the pathophysiology, which is attributed to alterations in gastrointestinal motility, visceral hypersensitivity, intestinal microbiota, gut epithelium and immune function, dysfunction of the brain-gut axis or certain psychosocial factors. Current therapeutic strategies are often unsatisfactory. There is now increasing evidence linking alterations in the gastrointestinal microbiota and IBS. Probiotics are living organisms which, when ingested in certain numbers, exert health benefits beyond inherent basic nutrition. Probiotics have numerous positive effects in the gastrointestinal tract. Recently, many studies have suggested that probiotics are effective in the treatment of IBS.

    Patients with inflammatory bowel disease (IBD) are increasingly becoming interested in nonpharmacologic approaches to managing their disease. One of the most frequently asked questions of IBD patients is what they should eat. The role of diet has become very important in the prevention and treatment of IBD. Although there is a general lack of rigorous scientific evidence that demonstrates which diet is best for certain patients, several diets—such as the low-fermentable oligosaccharide, disaccharide, monosaccharide, and polyol diet; the specific carbohydrate diet; the anti-inflammatory diet; and the Paleolithic diet—have become popular. This article discusses the diets commonly recommended to IBD patients and reviews the supporting data. PMID:27118948

    Irritable bowel syndrome (IBS) is a common chronic gastrointestinal disorder that is characterized by intermittent abdominal pain/discomfort, altered bowel habits and abdominal bloating/distension. This review aimed at presenting the recent developments concerning the role of diet in the pathophysiology and management of IBS. There is no convincing evidence that IBS patients suffer from food allergy/intolerance, and there is no evidence that gluten causes the debated new diagnosis of non-coeliac gluten sensitivity (NCGS). The component in wheat that triggers symptoms in NCGS appears to be the carbohydrates. Patients with NCGS appear to be IBS patients who are self-diagnosed and self-treated with a gluten-free diet. IBS symptoms are triggered by the consumption of the poorly absorbed fermentable oligo-, di-, monosaccharides and polyols (FODMAPs) and insoluble fibre. On reaching the distal small intestine and colon, FODMAPS and insoluble fibre increase the osmotic pressure in the large-intestine lumen and provide a substrate for bacterial fermentation, with consequent gas production, abdominal distension and abdominal pain or discomfort. Poor FODMAPS and insoluble fibres diet reduces the symptom and improve the quality of life in IBS patients. Moreover, it changes favourably the intestinal microbiota and restores the abnormalities in the gastrointestinal endocrine cells. Five gastrointestinal endocrine cell types that produce hormones regulating appetite and food intake are abnormal in IBS patients. Based on these hormonal abnormalities, one would expect that IBS patients to have increased food intake and body weight gain. However, the link between obesity and IBS is not fully studied. Individual dietary guidance for intake of poor FODMAPs and insoluble fibres diet in combination with probiotics intake and regular exercise is to be recommended for IBS patients.

    There is a layer of mucus lining the gastrointestinal tract, which acts as both a lubricant and as a physical barrier between luminal contents and the mucosal surface. The mucins that make up this layer consist of a protein backbone with oligosaccharides attached to specific areas of the protein core. These areas are called the variable number tandem repeat regions. The degree of glycosylation of the mucins is central to their role in the mucus barrier. The oligosaccharides are variable and complex. It has been demonstrated that the degree of sulphation and sialylation and the length of the oligosaccharide chains all vary in inflammatory bowel disease. These changes can alter the function of the mucins. Mucins are broadly divided into two groups, those that are secreted and those that are membrane bound. The major mucins present in the colorectum are MUC1, MUC2, MUC3, and MUC4.
Trefoils are a group of small peptides that have an important role in the mucus layer. Three trefoils have been demonstrated so far. They seem to play a part in mucosal protection and in mucosal repair. They may help to stabilise the mucus layer by cross linking with mucins to aid formation of stable gels. Trefoils can be expressed in the ulcer associated cell lineage, a glandular structure that can occur in the inflamed mucosa. There seem to be differences in the expression of trefoils in the colon and the small bowel, which may imply different method of mucosal repair.

    Abstract: Patients with inflammatory bowel diseases often undergo surgical procedures for medically refractory disease or colitis associated dysplasia. Endoscopic evaluation of the surgically altered bowel is often needed to assess for disease recurrence, its severity, and for therapy. It is important to obtain and review the operative report and abdominal imaging before performing the endoscopy. Diagnostic and therapeutic endoscopy can be safely performed in most patients with inflammatory bowel disease with altered bowel anatomy under conscious sedation without fluoroscopy. Carefully planned stricture therapy with balloon dilation or needle knife stricturotomy can be performed for simple, short, and fibrotic strictures. A multidisciplinary approach involving a team of endoscopist, endoscopy nurse, colorectal surgeon, gastrointestinal pathologist, and gastrointestinal radiologist is important for a safe and effective endoscopy. We attempt to review the aspects that need consideration before the endoscopy, the technique of endoscopy, and briefly the therapies that can be performed during endoscopy of the bowel through an ileostomy, a colostomy, in the diverted large bowel or ileal pouch, and small bowel after stricturoplasty and bowel bypass surgery in patients with inflammatory bowel diseases.
