Life-threatening sepsis following treatment for haemorrhoids: a systematic review.

INTRODUCTION: Haemorrhoids are a common complaint with estimates suggesting a prevalence of 4% of the adult population. Treatments such as rubber band ligation (RBL), sclerotherapy and excisional surgery have been in use for many years, and recently stapled haemorrhoidopexy, or procedure for prolapsing haemorrhoids (PPH) has gained acceptance. However, there have been consistent reports of severe sepsis, including a number of deaths. The purpose of this review was to assess the scale of the problem, and identify any predisposing factors, common presenting features, and treatment options in those who suffer these complications. RESULTS: Twenty-nine papers were identified, reporting 38 patients. Of these, 17 had undergone RBL, three had sclerotherapy, one had cryotherapy, 10 had excisional surgery and seven had PPH. Ten died as a result of their sepsis. The cases included 16 with perineal sepsis, seven with retroperitoneal gas and oedema, and six with liver abscesses. Common presenting features were urinary difficulties, fever, severe pain, septic shock and leucocytosis. Most were managed by means of surgery, although a minority survived having received conservative therapy. With the exception of two patients (one of whom was human immunodeficiency virus positive and the other had a drug-induced agranulocytosis) all were well prior to surgery. CONCLUSIONS: Although extremely uncommon, severe sepsis does occur post-treatment for haemorrhoids and all surgeons who treat such patients should be aware of the potential complications and alert to their presenting features. Early presentation without evidence of tissue necrosis may be managed conservatively, although most cases are managed by means of surgery.

Factors predicting early recurrence after transanal endoscopic microsurgery excision for rectal adenoma.

INTRODUCTION: Transanal endoscopic microsurgery (TEM) is an accepted way of excising rectal adenomas with low morbidity and mortality, avoiding major resectional surgery. However, there are no agreed criteria for surveillance following TEM. The purpose of this study was to identify criteria to guide surveillance programmes, thus reducing the surveillance burden for those patients at low risk of recurrence. PATIENTS AND METHODS: Patients who had undergone TEM for rectal adenomas were identified, and a retrospective review of patient, pathological and histological parameters was performed. RESULTS: Seventy-five (40 male) patients were identified; median age 70 years (39-85). There were seven tubular, 33 tubulo-villous and 35 villous adenomas. All were considered completely excised by the operating surgeon. Forty-seven (62.7%) were reported as being completely excised histologically. There was no significant association between recurrence at 6 months and sex, age, type or position of adenoma, height above the anal verge, or degree of dysplasia. Recurrence rates at six months were 0% for the completely excised adenomas and 21.4% for the incompletely excised ones; this was statistically significant (Pearson chi(2), P < 0.001). In all there were 12 recurrences, 10 in the incompletely excised group at a median follow up of 31 (6-80) months (P < 0.001). In addition, a significant association for large adenomas to recur was noted at median follow up (Armitage Trend test, P = 0.019). CONCLUSIONS: Histological assessment of completeness of excision of rectal adenoma and size of adenoma are important predictors of early recurrence and have potential to guide follow-up strategies after TEM.
