Is there a post-PPH syndrome?

BACKGROUND: Despite early studies reporting significant decreases in postoperative pain and morbidity with the procedure for prolapse and hemorrhoids (PPH) compared to traditional hemorrhoidectomy, certain complications and long-term efficacy remain uncertain. This study was performed to assess the prevalence of usage of PPH and the observed postoperative complaints and complications. METHODS: A questionnaire was mailed to national and international members of the American Society of Colon and Rectal Surgeons (ASCRS) and the accumulated data were reviewed. RESULTS: The rate of response to the 2,642 questionnaires was 28.5% (n=754). Of the 754 respondents, 531 (70.4%) had performed PPH and 451 (84.9%) continued to perform PPH. The most commonly reported postoperative complaint was delayed postoperative pain. Pain lasting for months was reported by 15.1% of respondents. Persistent bleeding was reported by 34.5%, and 40.9% felt there is a post-PPH syndrome. CONCLUSIONS: Some long-term studies critically examining PPH have come to fruition. A majority of respondents continued to perform PPH. Nearly half of these agreed that there is a "post-PPH syndrome" relating to postoperative morbidities. The most disturbing morbidity was lasting perineal pain of unexplained etiology demanding challenging management. Persistent bleeding from hemorrhoidal disease distal to the staple line requires further management and raises the question as to the use of PPH as a permanent remedial procedure.

Anhydrous ammonia burns case report and review of the literature.

Chemical burns are associated with significant morbidity, especially anhydrous ammonia burns. Anhydrous ammonia is a colorless, pungent gas that is stored and transported under pressure in liquid form. A 28 year-old patient suffered 45% total body surface area of second and third degree burns as well as inhalational injury from an anhydrous ammonia explosion. Along with fluid resuscitation, the patient's body was scrubbed every 6 h with sterile water for the first 48 h to decrease the skin pH from 10 to 6-8. He subsequently underwent a total of seven wound debridements; initially with allograft and then autograft. On post burn day 45, he was discharged. The injuries associated with anhydrous ammonia burns are specific to the effects of ammonium hydroxide. Severity of symptoms and tissue damage produced is directly related to the concentration of hydroxyl ions. Liquefactive necrosis results in superficial to full-thickness tissue loss. The affinity of anhydrous ammonia and its byproducts for mucous membranes can result in hemoptysis, pharyngitis, pulmonary edema, and bronchiectasis. Ocular sequelae include iritis, glaucoma, cataracts, and retinal atrophy. The desirability of treating anhydrous ammonia burns immediately cannot be overemphasized. Clothing must be removed quickly, and irrigation with water initiated at the scene and continued for the first 24 h. Resuscitative measures should be started as well as early debridement of nonviable skin. Patients with significant facial or pharyngeal burns should be intubated, and the eyes irrigated until a conjunctivae sac pH below 8.5 is achieved. Although health care professionals need to be prepared to treat chemical burns, educating the public, especially those workers in the agricultural and industrial setting, should be the first line of prevention.
