1/22. pneumocephalus secondary to colonic perforation by ventriculoperitoneal shunt catheter.We present a case of colonic perforation as a complication arising from ventriculoperitoneal shunt catheter. A 58-year-old woman with a ventriculoperitoneal shunt catheter inserted for obstructive hydrocephalus was admitted to hospital with signs and symptoms of meningitis. CT showed an air-fluid level within both lateral ventricles, raising the possibility of colonic perforation since no other aetiology for the pneumocephalus could be found. The CT demonstration of the colonic perforation played a crucial role in patient management.- - - - - - - - - - ranking = 1keywords = colon (Clic here for more details about this article) |
2/22. Iatrogenic lesions of the colon and rectum.Our ability to document a number of examples of iatrogenic lesions of the colon and rectum in three general hospitals confirms the multiplicity of these lesions as presented in the literature. It appears that the careful surgeon and his associates would well heed the old admonition known as Murphy's law, that "Anything that can go wrong will go wrong." In the daily practice of the general surgeon and proctologist, it is apparent that gentleness in approaching any anal-rectal examination for either diagnostic or therapeutic purposes is mandatory. The insertion of any foreign object, be it an examining finger, a thermometer, enema tip, or proctoscope, may subject the patient to an inadvertent injury of significant proportion. The dangers inherent in the evaluation and treatment of patients with recognized disease processes is significantly greater than that associated with routine and screening examinations. morbidity and mortality have been shown to be associated with the barium enema as well as with the barium enema as well as with some of the newer radiologic procedures such as mesenteric angiography. The use of tap water for enemas has produced morbidity both from thermal injuries and from electrolyte depletion. Antibiotics and chemotherapeutic drugs frequently result in colon and rectal disease, and therapeutic procedures directed at organs adjacent to the colon and rectum have resulted in a number of iatrogenic lesions. This reviews confirms reports of others that iatrogenic lesions of the colon and rectum are not solely due to the physician's inexperience, as significant numbers of these lesions were the result of the diagnostic or therapeutic efforts of men of considerable experience and skill. Advanced age of the patient and diseases leading to changes in the character of the bowel wall frequently were factors in the production of these lesions. A poorly prepared bowel has led to increased morbidity and mortality associated with iatrogenic perforations. The early recognition of these lesions and prompt medical and surgical management diminishes both the morbidity and mortality associated with such injuries.- - - - - - - - - - ranking = 1.1428571428571keywords = colon (Clic here for more details about this article) |
3/22. Percutaneous stenting of an latrogenic superior mesenteric artery dissection complicating suprarenal aortic aneurysm repair.PURPOSE: To report endovascular repair of an iatrogenic superior mesenteric artery (SMA) dissection caused by a balloon occlusion catheter. CASE REPORT: A 68-year-old man with a suprarenal aortic aneurysm underwent conventional prosthetic replacement, during which visceral artery back bleeding was controlled with balloon occlusion catheters. Six hours postoperatively, the patient experienced an episode of bloody diarrhea with abdominal pain and tenderness and mild metabolic acidosis. colonoscopy revealed colitis (grade I) without necrosis of the right and left colon. An emergent abdominal computed tomographic scan showed signs of mesenteric ischemia with bowel dilatation and SMA wall hematoma; angiography identified a dissection 1 cm distal to the SMA origin. An Easy Wallstent was deployed percutaneously, successfully reestablishing SMA patency. The postoperative course was uneventful, and the patient remains asymptomatic with a patent SMA stent and aortic graft at 1 year. CONCLUSIONS: latrogenic SMA dissection should be suspected after suprarenal aortic aneurysm repair if signs of mesenteric ischemia arise. Prompt and thorough imaging studies are necessary to confirm the diagnosis and assess the potential for an endoluminal treatment.- - - - - - - - - - ranking = 0.14285714285714keywords = colon (Clic here for more details about this article) |
4/22. Laparoscopic management of colonoscopic perforations.Colonic perforation is a dangerous complication of colonoscopy, both diagnostic and therapeutic, and its management has become controversial. The question of conservative vs operative treatment is still under debate. Despite the recent expansion and wide acceptance of laparoscopy by surgeons, the feasibility of this technique as a means of treating abdominal emergencies has also been questioned. Of 575 patients admitted to our institution for abdominal emergencies between 1993 and 1998, 365 were treated via a laparoscopic approach. Two of these patients were treated for colonoscopic perforations, one after a diagnostic procedure and one after an operative procedure. Our technique employs an open umbilical approach with two other trocars introduced in the right iliac fossa and left flank. In the first case, a diverticular perforation of the subperitoneal rectum was suspected. The abdomen was copiously irrigated with saline solution and a drain was left in the pelvis. In the second patient, localized peritonitis was found in the left iliac fossa due to a microperforation of the sigmoid colon. It was repaired with a single absorbable suture. The postoperative course was unremarkable in both cases. In patients with an emergency abdomen due to a postcolonoscopy perforation, we consider the laparoscopic approach feasible and safe in experienced hands. It allowed us to avoid an unnecessary laparotomy and other time-consuming and expensive diagnostic investigations. This approach represents an excellent means of managing this type of emergency abdominal situation.- - - - - - - - - - ranking = 1.1428571428571keywords = colon (Clic here for more details about this article) |
5/22. A case of successful management of maternal septic shock with multiple organ failure following amniocentesis at midgestation.Maternal sepsis is an unusual but catastrophic complication of amniocentesis. We report a case of successful treatment of maternal septic shock and multiple organ failure following amniocentesis at midgestation, possibly due to needle puncture of the sigmoid colon, which was tightly adherent to the anterior surface of the pregnant uterus.- - - - - - - - - - ranking = 0.14285714285714keywords = colon (Clic here for more details about this article) |
6/22. Cutaneous alternariosis in association with scabies or iatrogenic Cushing's syndrome.Cutaneous alternariosis is rare. Most infections occur in immunocompromised hosts. We report the first three cases in taiwan. The patients were elderly farmers residing in Tainan. They developed indolent, erythematous, ulcerated or crusted papules, plaques or pustules over the extensor aspect of the forearms or hands. Pure colonies of alternaria sp were isolated from biopsy specimens in each case. The diagnosis was confirmed by detecting pleomorphic fungal elements in the dermis within suppurative, granulomatous infiltrates. All three patients were immunocompromised. They showed a negative reaction to an intradermal test of seven common antigens. Cases 2 and 3 had iatrogenic Cushing's syndrome. Cases 1 and 3 had extensive scabies, which in Case 1 was of the Norwegian type. To the best of our knowledge, scabies associated with alternariosis has not been reported previously. The infection showed spontaneous regression in Case 1; in Case 2, it resolved after seven weeks of intralesional amphotericin b at a dose of 1 mg/mL twice a week.- - - - - - - - - - ranking = 0.14285714285714keywords = colon (Clic here for more details about this article) |
7/22. Acute superior mesenteric artery syndrome following left hemicolectomy: a case report.Acute superior mesenteric artery syndrome (SMAS) following a major surgical procedure is extremely rare, and represents an iatrogenic cause of postoperative upper gastrointestinal obstruction. In this report, the first documented case of acute SMAS following a left hemicolectomy is presented in an obese patient. Upper gastrointestinal roentgenographic series and conservative management remain to be the first line diagnostic and therapeutic modalities and were successful in our patient. Up to date no patient with SMAS reported to be obese but apparently obesity per se, can not be considered as an insurance. A postoperative acute SMAS is impossible to predict depending on the previous history, predisposing factors and the physique of the patient. Therefore, the surgeon should be aware of the SMAS and it is his task to secure all the precautions in order to preclude excessive traction on the mesenteric vasculature and vascular compression of the duodenum during surgery. In cases in which SMAS is suspected during extended colonic resections with lymph node dissection, duodenal mobilization seems to be selectively justifiable.- - - - - - - - - - ranking = 0.14285714285714keywords = colon (Clic here for more details about this article) |
8/22. G-CSF enables completion of tuberculosis therapy associated with iatrogenic neutropenia.neutropenia is a rare complication of anti-tuberculous therapy and is usually due to a single agent, most frequently isoniazid. The current case describes a previously healthy immunocompetent patient with tuberculosis of the lymph nodes who developed neutropenia due to a number of first line antibiotics (rifampicin, isoniazid and ethambutol) and streptomycin when introduced in combination and individually thus resulting in repeated treatment disruption. The introduction of twice-weekly subcutaneous granulocyte-colony stimulating factor to correct iatrogenic neutropenia facilitated the continuation and eventual completion of therapy without adverse effect. This is the first description of the use of granulocyte-colony stimulating factor to correct iatrogenic neutropenia due to anti-tuberculous antibiotics and the second description of the occurrence of iatrogenic neutropenia to more than anti-tuberculous antibiotic in an individual.- - - - - - - - - - ranking = 0.28571428571429keywords = colon (Clic here for more details about this article) |
9/22. Management of recurrent anastomotic stricture and iatrogenic stenosis by circular stapler.Anastomotic stricture is an increasingly common clinical finding. It is thought to arise because of ischemia, disruption, or leakage at an anastomosis site. Its management can be difficult and strictures often are resistant to standard dilation therapy. Major corrective surgery is possible; however, it is technically challenging and not without risk. We have used a circular stapler to excise colorectal strictures, introducing the anvil of the stapler via a proximal stoma or colotomy, drawing the anvil through the stricture with a snare via a colonoscope and affixing it to the body of a circular staple gun and excising the stricture. We have with found this to be an effective treatment in appropriately selected patients.- - - - - - - - - - ranking = 0.14285714285714keywords = colon (Clic here for more details about this article) |
10/22. barium peritonitis--following barium enema of the proximal colon through a colostomy.Perforation with extravasation of barium is a rare complication of contrast enema examination of the large bowel with a high associated mortality rate. The experience of performing a re-laparotomy in a patient previously exposed to barium peritonitis is even less common. We describe an elderly male patient with a Hartmann's procedure performed a year previously, presenting with peritonitis following barium enema evaluation of the proximal colon via an end descending colon stoma. Emergency laparotomy, segmental bowel resection and liberal peritoneal toilet resulted in a satisfactory outcome. The patient had a subsequent successful reversal of his Hartmann's procedure nine months later despite the presence of dense barium induced adhesions. This potentially preventable iatrogenic complication is discussed in this report, which is supplemented by a brief review of the English literature.- - - - - - - - - - ranking = 0.85714285714286keywords = colon (Clic here for more details about this article) |
