1/10. Prickly pear fruit bezoar presenting as rectal perforation in an elderly patient.BACKGROUND AND AIMS: Prickly pear fruit rectal seed bezoars are an extremely rare entity. Only nine cases of rectal seed bezoar have been reported, only one of which involved the prickly pear fruit seed. Furthermore, to our knowledge, this is also the first reported case presenting as rectal perforation. patients AND methods: We report a case of prickly pear fruit bezoar occurring in the elderly whom presented with rectal perforation. Consistent with physical signs, laboratory results, and radiological findings the patient was diagnosed with acute perforation of the rectum. A Hartman procedure was performed, and a colostomy was placed. RESULTS: Currently there are very few data regarding seed bezoars reaching the rectum. There are even fewer data concerning this occurrence in the elderly, and the literature contains no report of this phenomenon presenting or even progressing into perforation. We report this rare entity to the existing literature. CONCLUSION: We report a rare but important case. A prickly pear fruit phytobezoar presenting as rectal perforation. This case may add to the increasing awareness of the danger associated with ingestion of certain foodstuffs. The previously benign sunflower and psyllium seeds are now known to cause bezoar. We feel that the prickly pear fruit should join this small but important list.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/10. Retrorectal cyst: a rare tumor frequently misdiagnosed.BACKGROUND: The rarity of retrorectal cysts and their nonspecific clinical presentations often lead to misdiagnoses and inappropriate operations. In recent years, several such patients have been referred to our institutions for evaluation and treatment of misdiagnosed retrorectal cysts. A review of these patients is presented. STUDY DESIGN: medical records of the colorectal surgery divisions at two institutions were reviewed. patients found to have previously misdiagnosed retrorectal cysts were identified. Preliminary diagnoses, radiologic examinations, operative procedures, and final diagnoses were obtained. RESULTS: Seven patients with retrorectal cysts who had been misdiagnosed before referral were identified. These patients had been treated for fistulae in ano, pilonidal cysts, perianal abscesses; psychogenic, lower back, posttraumatic, or postpartum pain, and proctalgia fugax before the correct diagnosis was made. patients underwent an average of 4.1 operative procedures. physical examination in combination with CT scanning made the correct diagnosis in all patients. All patients underwent successful resection through a parasacrococcygeal approach, and six of seven did not require coccygectomy. The resected tumors included four hamartomas, two epidermoid cysts, and one enteric duplication cyst. CONCLUSIONS: Retrorectal cysts are a rare entity that can be difficult to diagnose without a high index of clinical suspicion. A history of multiple unsuccessful procedures should alert the clinician to the diagnosis of retrorectal cyst. Once suspected, the correct diagnosis can be made with physical examination and a CT scan before a definitive surgical procedure.- - - - - - - - - - ranking = 6.5238032192045keywords = physical examination, physical (Clic here for more details about this article) |
3/10. Functional constipation with impaired rectal sensation improved by electrical stimulation therapy: report of a case.patients with intractable constipation often complain of social, physical, and psychologic stress. Recently, biofeedback therapy has been widely used for the management of intractable constipation, particularly in cases of constipation associated with pelvic floor dyssynergia. However, some constipated patients often complain of absent or diminished sense of wanting to defecate. It is unclear whether impaired rectal sensation is a cause or outcome of constipation and what specific treatment is available for these patients. We treated a 25-year-old female patient who complained of intractable constipation for ten years. colon transit time study and defecography showed nonspecific findings. Her anorectal manometric findings were within normal ranges with the exception of impaired rectal sensation. Rectal sensory threshold volumes for desire and urge to defecate and maximal tolerated volume were greatly increased. She was treated by electric stimulation therapy for the purpose of improving impaired rectal sensory function. After 14 sessions of electric stimulation therapy, her constipated symptoms improved dramatically. Furthermore, the desire and urge threshold volumes were remarkably decreased. We report this case of constipation with impaired rectal sensation possibly treated by electric stimulation therapy.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
4/10. Visceral myopathy of the colon mimicking Hirschsprung's disease. diagnosis by deep rectal biopsy.A 51-year-old man presented with a history and physical findings consistent with adult Hirschsprung's disease. An inadvertent transmural rectal biopsy led to the unexpected diagnosis of a visceral myopathy, a diagnosis which was confirmed by subsequent colectomy. The pathological findings are reviewed, and the potential use of transmural rectal biopsy in the diagnosis of smooth muscle disorders of the colon is discussed.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
5/10. anticoagulants and abdominal pain. The role of computed tomography.The development of abdominal pain in the patient receiving anticoagulants, especially with a documented drop in hematocrit levels, almost certainly indicates a major hemorrhage. If loss of blood from the GI tract is not documented, some form of internal bleeding must have occurred. Unfortunately, the site of the bleeding is frequently unclear. Even small hemorrhages in critical locations (eg, the adrenal gland) can have serious consequences. In the obese patient, a rectus sheath hematoma may remain hidden at the time of repeated physical examinations. Generally, the cause of a mass palpated or perhaps demonstrated by conventional radiological studies cannot be diagnosed accurately. Computed tomography can demonstrate the size and location of the mass and its relation to normal intra-abdominal structures. By careful evaluation of the attenuation coefficient, it is possible to establish the definitive diagnosis of hemorrhage. Should the attenuation value of a mass be insufficiently high to diagnose hemorrhage conclusively on the initial scan, serial scans demonstrating a decrease in size and/or attenuation of the mass confirm the diagnosis of hemorrhage. In our opinion a negative CT examination is a reliable indicator that such a bleeding complication has not occurred.- - - - - - - - - - ranking = 6.5238032192045keywords = physical examination, physical (Clic here for more details about this article) |
6/10. Congenital rectal stenosis: a sign of a presacral pathologic condition.Congenital rectal stenosis may be detected in the newborn during the initial physical examination. Failure of conservative therapy (dilatation) should alert the physician to the presence of an associated pathologic condition in the presacral space. Presacral teratoma, anterior sacral meningocele, or bony anomalies may be the underlying extrinsic causes of congenital rectal stenosis. Prompt recognition and appropriate operative management directed at the presacral lesion will relieve obstructive symptoms and minimize morbidity.- - - - - - - - - - ranking = 6.5238032192045keywords = physical examination, physical (Clic here for more details about this article) |
7/10. Proctalgia fugax.Proctalgia fugax is a fairly common but little-known cause of rectal pain. It is a benign condition that has no known etiology. Symptoms consist of episodic, sudden, sharp pain in the anorectal area, usually lasting several seconds to several minutes. diagnosis is based on a history that fits the classic picture, coupled with a normal physical examination. Several treatments have been tried and found anecdotally to be effective, although reassurance is the most useful therapeutic option.- - - - - - - - - - ranking = 6.5238032192045keywords = physical examination, physical (Clic here for more details about this article) |
8/10. Let the finger linger.Retrorectal masses are rare and of insidious onset. We report a consecutive series of six such cases (males = 4, females = 2). The main presenting complaint was back pain and the most reliable physical sign was a palpable mass posteriorly on rectal examination (all cases). C T scan was the most radiologically informative investigation. Surgical intervention was undertaken using both anterior (trans-abdominal) and posterior (retrorectal) approaches. The majority of the masses excised were benign and all patients, to date, remain well.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
9/10. Paroxysmal anal hyperkinesis: a characteristic feature of proctalgia fugax.BACKGROUND AND AIMS: Proctalgia fugax is a common problem, yet its pathophysiology is poorly understood. The objective was to characterise colorectal disturbances in a paraplegic patient with a 10 year history of proctalgia fugax that began two years after an attack of transverse myelitis. methods: Standard anorectal manometry and prolonged 33 hour ambulatory colonic manometry at six sites in the colon were performed together with myoelectrical recording of the anus. Provocative tests designed to simulate psychological and physical stress and two types of meals were included. RESULTS: Anorectal manometry showed normal internal sphincter tone and normal rectoanal inhibitory reflex but an inability to squeeze or to bear down or to expel a simulated stool. Rectal sensation (up to 360 ml inflation) was absent. pudendal nerve latency was prolonged (4.5 ms (normal < 2.2 ms). During colonic manometry, the patient reported 27 episodes of pain, of which 23 (85%) were associated with bursts (1-60 min) of a high amplitude (0.5 to > 3.2 mv), high frequency (5-50/min) anal myoelectrical activity, particularly after stress tests, meals, and at night. The myoelectrical disturbance only occurred with proctalgia. Intermittently, 16 bursts of 3 cycles/ min phasic rectal contractions were seen, but only six were associated with proctalgia. Colonic motility was reduced compared with normal subjects. CONCLUSIONS: The temporal association between a high amplitude, high frequency myoelectrical activity of the anal sphincter, and the occurrence of proctalgia suggests that paroxysmal hyperkinesis of the anus may cause proctalgia fugax.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
10/10. Spontaneous perforation of the rectum with possible stercoral etiology: report of a case and review of the literature.Stercoral perforation of the colon or rectum is a rare cause of acute abdomen, with fewer than 70 cases documented in the literature. We report herein the case of a 60-year-old man who presented with anuria and epigastric pain with physical signs of peritonitis. An abdominal X-ray showed bilateral subphrenic free air accumulation, and an emergency laparotomy subsequently revealed perforation of the rectum, suggestive of a stercoral cause, which was treated by simple closure after debridement. Following an uneventful postoperative course, he was discharged from the hospital 3 weeks after his operation and is now doing well without having suffered any further gastrointestinal problems. The clinical features, diagnosis, and treatment of the disease are reviewed following the presentation of this case. Surgeons should be aware of the possibility of this fatal disease, despite its rare incidence. Furthermore, it is important to recognize the condition at an early stage because it has a significantly high mortality if not treated early. Conversely, the surgical outcome is satisfactory provided surgery is performed in due time.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
