Aspiration for acute pilonidal abscess-a cohort study.

BACKGROUND: The traditional open incision and drainage of a pilonidal abscess is associated with slow healing and delayed return to normal daily activities. The aim of this study is to assess safety, effectiveness, and patient satisfaction of aspiration followed by antibiotics for a pilonidal abscess. MATERIAL AND METHODS: All patients presenting with an acute pilonidal abscess during the period December 2010 and December 2014 in York Hospital, UK, were treated with bedside aspiration under local anesthetic, followed by oral cefalexin and metronidazole for 7 days. Patients with immunosuppression, diabetes, overlying skin necrosis, and perforation were excluded. Complications of the procedure were prospectively recorded. Long-term outcomes and overall patients' satisfaction were assessed with the use of mailed questionnaires and Visual Analogue Scales (VAS) (0 = not satisfied at all, 10 = very satisfied). RESULTS: One hundred sixty-nine patients presented with an acute pilonidal abscess and a total of 100 patients were treated with aspiration and antibiotics. There were 50 women (50%) and the median (interquartile range [IQR]) age of the cohort was 24 (14) years. Eleven patients had a history of a previous pilonidal procedure. Seven patients were treated successfully with a reaspiration. Overall, 10 patients required incision and drainage after a median (IQR) follow-up time of 29 (47) months. Fifty-six patients returned completed questionnaires. The median (IQR) of the VAS for the overall satisfaction of the procedure was 9 (5). CONCLUSIONS: Aspiration of a pilonidal abscess in selected patients is effective in 83%, and it is associated with high overall satisfaction rates.

Does preoperative depression and/or serotonin transporter gene polymorphism predict outcome after laparoscopic cholecystectomy?

OBJECTIVE: To determine whether preoperative psychological depression and/or serotonin transporter gene polymorphism are associated with poor outcomes after the common procedure of laparoscopic cholecystectomy. DESIGN: Patients undergoing laparoscopic cholecystectomy were genotyped for the serotonin transporter gene 5-HTTLPR polymorphism and assessed for psychological morbidity before and 6 weeks after surgery. The main outcome was postoperative depression; secondary outcomes included fatigue, perceived pain, quality of life and subjective perception about return to usual. RESULTS: Full genetic and psychological data were obtained from 273 out of 330 patients consented to the study (82% female). Significantly fewer people with preoperative depression (Beck Depression Inventory (BDI) score >5) had returned to employment (57% vs 86%, p<0.001) or made a full recovery (11% vs 44%, p<0.001) 6 weeks after surgery. Independent predictors for subjective return to usual after surgery included preoperative depression, body mass index and postoperative pain scores. Independent predictors of postoperative depression included preoperative antidepressant use and preoperative depression. SS genotype was associated with use of antidepressants preoperatively and higher anxiety levels after surgery. However, it was not associated with other salient postoperative psychosocial outcomes. CONCLUSIONS: Depressive psychological morbidity preoperatively, pain and body mass index appear to be important factors in predicting recovery after this common surgical procedure. There may be a place to include preoperative brief psychological screening to enable targeted support. Our results suggest that the serotonin transporter gene is unlikely to be a useful clinical predictor of outcome in this group. TRIAL REGISTRATION NUMBER: ISRCTN40219584.

Faecal calprotectin in patients with suspected colorectal cancer: a diagnostic accuracy study.

BACKGROUND: NICE guidance exists for the use of faecal calprotectin (FC) when irritable bowel syndrome or inflammatory bowel disease are suspected. Often, however, colorectal cancer is considered within the differential. Should FC have a high diagnostic accuracy for colorectal cancer, it may be applicable as a primary care screening test for all patients with lower gastrointestinal symptoms. AIM: To determine the negative and positive predictive value (NPV/PPV) of FC in patients referred from primary care with suspected colorectal cancer. DESIGN AND SETTING: A diagnostic accuracy study conducted at a single secondary care site METHOD: Consenting patients referred with suspected colorectal cancer within the '2-week wait' pathway provided a stool sample for FC prior to investigation. FC levels were reconciled with end diagnoses: cancer, adenomatous polyps ≥10 mm, and all enteric organic disease. RESULTS: A total of 654 patients completed the evaluation; median age 69 years, female 56%. The NPV for colorectal cancer was 98.6% and 97.2% when including polyps ≥10 mm. The PPV for all organic enteric disease was 32.7%. The diagnostic yield for cancer based on clinical suspicion was 6.3%. By altering the FC cut-off to fix the NPV at 97.0%, the PPV for cancer increased from 8.7% to 13.3%. CONCLUSION: FC has a high NPV for colorectal cancer and significant polyps in patients with suspected cancer. In total, 27.8% of patients had a normal FC and could safely have been spared a '2-week wait' referral. The addition of FC testing into the current symptom-based assessment has the potential to increase colorectal cancer detection rate yet be clinically and cost effective.

Is Early Reversal of Defunctioning Ileostomy a Shorter, Easier and Less Expensive Operation?

BACKGROUND: A defunctioning loop ileostomy mitigates the consequences of anastomotic leak from low rectal anastomosis but it is associated with significant morbidity. In this study, the outcome of early reversal of defunctioning ileostomy during the same admission with the primary operation was assessed. METHODS: This randomized study was carried out at York Teaching Hospital during the period 2003-2007. All patients with defunctioning ileostomy were considered for an early second operation if they had an uneventful recovery and were in good general condition. Patients on steroids, at high cardiorespiratory risk and those experiencing any postoperative complication were excluded. Eligible patients with satisfactory gastrografin enema on postoperative day 6 were randomized to early versus late reversal at 6-8 weeks. Outcome measures were ease of closure as assessed by a visual analog scale by the operating surgeon, all postoperative complications, duration of the operation, total length of hospital stay and associated costs. RESULTS: Thirty-nine consecutive patients were assessed for eligibility and finally 26 were included in the study. Sixteen patients underwent early reversal. The median(interquartile range (IQR)) age was 62(22) years. Early reversal was significantly superior in terms of ease of abdominal wall closure, ease of reversal (p < 0.01 each), duration of the operation (median(IQR) 20(13) vs. 40(9) min, p < 0.01) and costs of stoma care (median(IQR) 27(9) vs. 311(108) £, p < 0.01). There were no major (grade III/IV) complications in either group. Total length of hospital stay was similar between groups. CONCLUSION: In carefully selected patients, early reversal of defunctioning ileostomy is feasible, technically easier and has shorter operative time which can also lead to significant cost savings.

Converting emergency pilonidal abscess into an elective procedure.

BACKGROUND: Improvements in outcome after surgery for elective pilonidal sinus disease have yet to be matched for those presenting with acute disease. Traditional approaches to the management of acute pilonidal abscess have been associated with slow healing and significant loss of working time. OBJECTIVE: The aim of this study was to report our approach in which a temporizing intervention allows subsequent definitive treatment with low morbidity. DESIGN: This article presents a prospective cohort study. SETTING: This study was performed in acute admissions to the Surgical Unit in York Teaching Hospital. PATIENTS: Patients presenting with acute pilonidal abscess, not septic, immune-compromised, or diabetic, and without skin necrosis, underwent aspiration on the surgical ward. INTERVENTION: Aspiration of pilonidal abscess under local anesthetic was performed with the use of a wide-bore needle. The abscess cavity was drained to dryness, samples were sent to the laboratory for microbiology, and empirical oral antibiotics were commenced, covering anaerobes and aerobes. Review was arranged for within 7 days to plan elective excision and primary closure of the underlying pilonidal sinus. MAIN OUTCOME MEASURES: The primary outcomes measured were the number of days required to return to normal activities, response to treatment, and any residual inflammation. RESULTS: Fifty-six patients were referred with acute pilonidal abscess. Forty patients met the criteria for aspiration and empirical antibiotic treatment. All were allowed to go home the same day and were reviewed within a median of 5 days. Thirty-eight (38/40) patients demonstrated complete resolution of acute inflammation and were back to normal activities the following day. Fifteen patients subsequently underwent day-case excision and primary closure at a median of 9 weeks. Another 13 are awaiting surgery, and 10 patients have declined further treatment. Two (2/40) patients did not respond, one of whom did not receive the appropriate antibiotics. Both were managed with incision and drainage. CONCLUSIONS: Aspiration and antibiotic management of pilonidal abscess is effective in 95% of acute cases in preventing the need for emergent laying open and allows for subsequent elective surgery.

Botulinum toxin (botox) reduces pain after hemorrhoidectomy: results of a double-blind, randomized study.

PURPOSE: Pain after hemorrhoidectomy appears to be multifactorial and dependent on individual pain tolerance, mode of anesthesia, postoperative analgesia, and surgical technique. Spasm of the internal sphincter is believed to play an important role. The aim of this study was to assess the role of botulinum toxin in reducing pain after Milligan-Morgan hemorrhoidectomy. METHODS: This was a double-blind study of 50 consecutive patients undergoing Milligan-Morgan hemorrhoidectomy and assigned to an internal sphincter injection of 0.4 ml of solution containing either botulinum toxin (20 U; Botox) or normal saline. Patients were managed according to standardized perioperative analgesic and laxative regimens. Pain was assessed by use of daily visual analog scores and analgesia requirements for the first seven postoperative days. RESULTS: Patients randomized to receive botulinum toxin had lower daily average and maximal visual analog scores throughout the study period. The difference reached significance on both Day 6 (P < 0.05) and Day 7 (P < 0.05). There was no significant difference (P = 0.12) in morphine requirements in the first 24 hours (botulinum group, 16 (range, 6-27) mg; placebo arm, 22 (range, 13-41) mg). Patients who received Botox used 19 (range, 8-36) coproxamol tablets in the first seven days after surgery compared with 23 (range, 10-40) in the placebo arm (P = 0.63). CONCLUSIONS: Those patients who had botulinum toxin had significantly less pain toward the end of the first week after surgery. Reduction in spasm within the internal sphincter is the presumed mechanism of action. This is the first reported randomized, controlled trial using botulinum toxin in hemorrhoidectomy.
