Gas embolism after periproctal abscess incision and lavage with hydrogen peroxide a case report Should the use of hydrogen peroxide in surgery be continued?

INTRODUCTION: Hydrogen peroxide is an antiseptic solution still often used in surgical departments for lavage of wounds. Its use is nevertheless linked to an important risk of gas embolism. Such a case report has not yet been published in the Czech literature and awareness of this danger is low among surgeons. CASE REPORT: The author describes the case of gas embolism in a 40 years old patient after lavage of a periproctal abscess incision with 3% hydrogen peroxide. The lavage resulted in a cardiopulmonary arrest with the need of cardiopulmonary resuscitation. Fortunately, the patient recovered without any health consequences. CONCLUSION: In the view of important risks and questionable and insufficiently proven benefits it may be the time to possibly reconsider the use of hydrogen peroxide in surgery and replace it with a different antiseptic agent.

Lumbar hernia - case report.

INTRODUCTION: The author presents a case report of a rare lumbar hernia. CASE REPORT: A 69 years old woman came to our outpatient room with a big mass in the right lumbar area. The CT scan revealed a big lumbar hernia containing the right kidney, the colon and small intestine. The patient underwent an uneventful open hernioplasty with the use of a prolene mesh. CONCLUSION: Lumbar hernia occurs very rarely. Open hernioplasty with the use of a mesh is the method of choice in big hernias. Small hernias can be repaired laparoscopically.

[Laparoscopic diverting ileostomy in rectal cancer surgery]. / Laparoskopická protektivní ileostomie v chirurgii karcinomu rekta.

INTRODUCTION: Low anterior resection (LAR) with total mesorectal excision (TME) represents the gold standard for patients with low rectal carcinoma. Protective ileostomy (PI) is commonly performed during LAR in an effort to protect low rectal anastomosis. The aim of this study is to analyse outcomes in our own patient population, focusing on morbidity associated with PI. METHOD: A retrospective clinical study of patients operated on between 2013 and 2015 was conducted in University Hospital Ostrava. All patients after LAR with PI due to low rectal cancer were included. The study design did not require randomisation. RESULTS: A total of 52 patients who underwent LAR with PI were included. Mean tumour height was 9.1±2.3 cm. 15.4% of the patients were classified as ASA I, 53.8% were classified as ASA II and 32.7% of the patients as ASA III. 30-day postoperative morbidity was 38.5%, and complications associated with PI (within 30 days after LAR) occurred in 7 (13.5%) patients. Three of these patients underwent urgent surgical revision due to small bowel obstruction (PI semirotation around its longitudinal axis in two patients and volvulus of the small bowel around PI in one patient). Mean time interval between PI creation and reversal was 252 days. During this period, complications associated with PI were detected in 25 (48.1%) patients; seven patients had more than one complication. Minor complications (such as peristomal dermatitis, stoma herniation or bleeding, wound infection after stoma reversal) were observed in 17 (32.7%) patients. Major complications (small bowel obstruction at the site of PI, dehydration due to high stoma output, intraabdominal abscess after stoma reversal) occurred in 8 (15.4%) patients. CONCLUSIONS: PI offers protection to low colorectal or coloanal anastomosis in rectal cancer surgery. However, this benefit is counterbalanced by a high risk of various complications which may occur during the whole period when PI is present. The decision for diversion should therefore be made only after careful consideration.Key words: rectal cancer - low anterior resection - laparoscopy - protective ileostomy - stoma complications.

[Perforation of the right ventricle of the heart as a complication of CT guided percutaneous drainage of a subphrenic abscess - a case report]. / Perforace pravé srdecní komory jako komplikace CT navigované perkutánní drenáze subfrenického abscesu kazuistika.

INTRODUCTION: CT guided percutaneous drainage is currently the gold standard in the treatment of abdominal fluid collections, having substituted open surgical drainage in many cases. It burdens the patient less than surgical drainage. Its efficiency is comparable to standard surgical drainage when properly indicated. It is readily available even in smaller hospitals. However, this method can also have many complications, which originate most often from an improperly targeted drainage catheter. CASE REPORT: The authors describe a case report of a 55 years old man with a right-sided subphrenic abscess. The right ventricle of the heart was perforated during a CT guided percutaneous drainage. The bleeding was minimal, but the patient suffered a profound septic shock as a result of massive bacteremia during direct communication of the contents of the abscess cavity with blood circulation. He was operated immediately. The right ventricle was sutured, and the subphrenic abscess was drained. There were no complications after the operation, and the patient was discharged on day 17 after the surgery. CONCLUSION: The CT guided drainage of an abdominal abscess or a fluid collection in a risk area should be preferably done in hospitals whose therapeutic portfolio also includes the handling of serious complications. KEY WORDS: heart injury drainage.

[Rare injury of perineum and anorectum - case report]. / Raritní poranení hráze a anorekta kazuistika.

UNLABELLED: Anorectal injuries, with the exception of iatrogenic damage, are rare. Considering the extensive range of causes and potential extent of damage, the diagnosis and treatment of these injuries requires an individual approach to every patient. Based on the extent of damage, the best way of treatment strategy has to be selected for successful treatment of the primary injury and elimination of frequent complications, especially fecal incontinence. The authors present a rare injury of the perineum and anorectum with anorectal sphincter damage in an elderly man after falling down from a stepladder. KEY WORDS: anorectum - anorectal trauma - anal sphincter.

[Secondary angiosarcoma of the abdominal wall after adjuvant radiotherapy in a patient with uterine carcinoma - a case report]. / Sekundární angiosarkom brisní steny po adjuvantní radioterapii pacientky s karcinomem delohy kazuistika.

INTRODUCTION: Adjuvant radiotherapy is an integral part of the current treatment of many malignant tumours. However, this mode of treatment does not provide only benefits in the sense of lowering the risks of recurrence, but it is also associated with many undesirable side effects, from which one of the most serious is the development of secondary malignancies. CASE REPORT: The author describes a case report of 77 years old woman who underwent hysterectomy with bilateral adnexectomy and pelvic lymphadenectomy for uterine carcinoma pT1bN0M0, G1 in 2005. Adjuvant external radiotherapy with the dose 45Gy and brachytherapy 3x4Gy followed. Subsequently the patient was followed at the department of gynecology, which referred her in January 2015 with a quickly growing tumour of the skin and subdermal tissue in the hypogastric area, where previous radiation had been applied. Its excision was indicated with the diagnosis of suspected uterine carcinoma metastasis, but subsequent histological evaluation confirmed angiosarcoma. Despite negative resection margins the tumour quickly recurred and disseminated. CONCLUSION: Angiosarcoma as a side effect of irradiation is described increasingly more often nowadays. The vast majority of cases are related to the treatment of breast carcinoma. Its prognosis is very poor and therapeutic possibilities are limited. Surgical excision with negative margins remains the mainstay of the treatment. It is necessary to keep this diagnosis in mind and patients undergoing radiation treatment should be followed over a long period. KEY WORDS: angiosarcoma.

[Fracture of the Anatomical Neck of the Humerus Associated with Posterior Shoulder Dislocation. Case Report]. / Zlomenina anatomického krcku humeru spojená se zadní luxací ramene ­ kazuistika.

A rare case of a fracture of the anatomical neck of the humerus associated with a posterior dislocation of the shoulder in a 43-year-old man is presented. It was managed by immediate surgery using locking plate osteosynthesis. The shoulder was immobilised for 5 weeks in a Gilchrist brace. The outcome was very good with a full range of motion and a stable shoulder at 1 year after injury, with no signs of avascular necrosis of the humeral head. The aetiology of this injury and possibilities of its treatment are discussed. Key words: shoulder dislocation, humeral fractures.

[Pruritus ani]. / Pruritus ani.

INTRODUCTION: Pruritus ani is defined as a dermatologic disease characterized by itching and/or burning in the perianal area. It occurs in 15% of the population. Men are affected more frequently than women, in the ratio 4:1. It is accompanied by an irresistible desire to scratch in the perianal area. Pruritus ani is divided into two subtypes: primary (idiopathic) and secondary. In idiopathic (primary) pruritus it is not possible to detect any other cause of itching. Secondary pruritus has an obvious causal origin.The aim of this paper is to offer a complex overview of possible causes, diagnostic procedures and treatment possibilities of this unpleasant and annoying disease. METHODS: We have researched available publications using PubMed and MEDLINE databases, focusing on articles on anal pruritus. At first the key word "Pruritus ani" was put in without any restrictions. Subsequently, we limited the selection by the time period of 5 years and 10 years; then we looked up articles in English, German and Czech languages, and finally review articles, clinical trials and others. RESULTS: 574 articles were found without entering any restrictions; 45 of them were review articles and 25 clinical trials. 437 articles were in the English language and 40 of them were review articles. 44 were in the German language and 1 of them was a review article. A total of 33 articles were found with a 5-year time limit. 6 of them were review articles and 4 were clinical trials. 66 articles from the last 10 years were found. 14 of them were review articles and 10 were clinical trials. In most of the other articles among the total number of articles found, pruritus ani was mentioned only marginally in articles focused on different topics. We have not found any summary articles on this topic in Czech publications. CONCLUSION: Pruritus ani is a common disease with a number of causes; therefore, effective treatment may be insufficient in the initial stages. The therapy is focused on the primary cause, if found. Broad differential diagnosis options need to be taken into consideration, and reevaluation of the therapy is a priority. When no obvious secondary cause is found, the empiric treatment is focused on an improvement of hygiene and change in the life style, removal of common irritators, and protection of perianal skin.
