Delayed presentation of life-threatening perineal sepsis following stapled haemorrhoidectomy: a case report.

Fournier's gangrene has been described after injection sclerotherapy and banding of haemorrhoids as well as after conventional haemorrhoidectomy. In addition, there have been several cases following stapled haemorrhoidopexy. A patient with this complication nearly always presents within the first week following surgery. We present an illustrative case of a patient who underwent stapled haemorrhoidopexy for prolapsed haemorrhoids and presented with fever, urinary retention and peri-anal pain 39 days later. At re-operation, there was extensive peri-anal necrosis. After wide excision and fashioning of a colostomy, the patient recovered. Our case shows that late presentation can occur.

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.

Day-case laparoscopic hernia repair in a single unit.

BACKGROUND: Laparoscopic groin hernia repair has been shown to be a safe, well-tolerated procedure. Here, we report a series of patients who underwent laparoscopic transabdominal preperitoneal (TAPP) mesh repair as day cases. RESULTS: We performed 984 repairs on 769 patients, 218 had bilateral repairs. Mean operating time was 25 min for unilateral and 38 min for bilateral repairs. Three were converted, and 39 required admission. Five were readmitted more than 48 h postoperatively. Three required reoperation for small bowel obstruction from herniation through a peritoneal defect. Only 57% of patients required analgesia for a mean of 1.9 days after discharge. Recovery times were similar for unilateral and bilateral herniae. Eight hernias have recurred to date. CONCLUSIONS: Laparoscopic hernia repair is suitable for day-case surgery for unilateral, bilateral, and recurrent herniae. TAPP repair allows inspection of the contralateral groin, with repair of defects as necessary.

Subcellular localisation of cyclin D1 protein in colorectal tumours is associated with p21(WAF1/CIP1) expression and correlates with patient survival.

We investigated the expression of the cell cycle regulatory proteins cyclin D1 and p21(WAF1/CIP1) (p21) in human colorectal carcinomas using immunohistochemistry. Cyclin D1 was not detected in normal colonic epithelium; however, expression was observed in 74/126 (58.7%) of the tumour samples studied. Protein was detected in the nucleus in 22/126 (17.4%) and exclusively in the cytoplasm in 52/126 (41.3%) tumours. Nuclear expression of cyclin D1 was associated with poorly differentiated tumours (p = 0.035) and was more common in right- than in left-sided tumours (p = 0.005). Tumours displaying either, expression of cytoplasmic, (p = 0.05, HR 0.56, 95% CI 0.31-1.0) or nuclear (p = 0.021, HR 0.24, 95% CI 0.07-0.81) cyclin D1 were associated with improved patient survival compared with tumours negative for cyclin D1. p21 protein was strongly expressed mainly in the upper crypts of normal colonic epithelial cells, but in 63/126 (50%) of the tumour samples studied p21 expression was absent. Patients with tumours in which >50% of cells expressed p21 had improved survival compared to patients whose tumours were negative or had < or =50% of cells expressing p21 (p = 0.06, HR 0.33, 95% CI 0.1-1.0). We also observed a significant association between cyclin D1 subcellular localisation and p21 expression: 21/22 (95.5%) tumours expressing cyclin D1 in the nucleus also expressed p21, whereas only 17/52 (32.7%) of the tumours displaying exclusive cytoplasmic cyclin D1 staining were positive for p21 (p < 0.001). These data highlight the significance of exclusive cytoplasmic expression of cyclin D1 in colorectal cancer and lend support to recent in vitro studies suggesting that p21 protein may modulate the subcellular localisation of the cyclin D1 protein. Thus, deregulated expression of the cyclin D1 and p21 proteins are important in colorectal tumourigenesis and have implications for patient prognosis.
