Article: Single-center comparative study of laparoscopic versus open colorectal surgery: a 2-year experience.
[show abstract] [hide abstract]
ABSTRACT: To examine the change in practice from open to laparoscopic practice in our local trust, a national training colorectal unit. Retrospective comprehensive review of clinical case notes of all colorectal resections between October 2007 and October 2009. Patients were identified through clinical coding and data were analyzed using SPSS. Comparison of 113 open versus 103 laparoscopic colorectal surgeries for various indications and short-term outcomes was made. There was an expected overall increase in the laparoscopic colorectal resections. The mean age was 73 years for open and 68 years for laparoscopic surgeries. There was no significant difference between the 2 groups with respect to age, sex, and the American Society of Anaesthesiologists. Of the 103 patients who were initially treated with laparoscopy-assisted colectomy, 12 (11.7%) were shifted to open procedures. Perioperative recovery was faster in the laparoscopic-surgery group than in the open-colectomy group, as reflected by a shorter hospital stay (median, 8 vs. 13 d). The overall complication rate was significantly less in the laparoscopy-assisted colectomy group than in the open-colectomy group (33% vs. 46%, P=0.05). Our local hospital practices support the many benefits of laparoscopic colorectal surgery. Substantial improvements in rates of hospital stay and wound infection were noted, hence shifting our practice safely in a district general hospital.Surgical laparoscopy, endoscopy & percutaneous techniques 02/2012; 22(1):29-32. · 1.23 Impact Factor -

Article: Assessment of screening colonoscopy competency in colon and rectal surgery fellows: a single institution experience.
[show abstract] [hide abstract]
ABSTRACT: The American Board of Surgery and the American Board of Colorectal Surgery requirements for certification include 80 and 140 colonoscopic procedures, respectively. However, little data support the attainment of colonoscopic competency. The aim of this retrospective study is to report the colonoscopy learning experience for colorectal surgery fellows at a single high-volume training program. A prospective database recorded the experience of six colorectal fellows over two consecutive academic years. Univariate, moving average curves, and change point analysis were used to assess learning curve trends over time. Screening colonoscopy competency was defined by a significant reduction in total procedure time and 80% cecal intubation rate within 35 min. From 2004 to 2006, a total of 2904 screening colonoscopies were performed, including 1498 (52%) by fellows (mean 249 procedures per fellow). The mean procedure time for fellows was 30.2 ± 15 min. Procedure time decreased significantly up to 120 procedures but not thereafter. Overall, fellows' total procedure time decreased by 7.6 min over the course of the year (P < 0.0001); 66% of fellows were able to complete 80% of the procedure in 40 min in the last 2 mo of training. The combined learning curve of all the fellows and the change point analysis showed a significant change occurs at 94 procedures. Using the moving average curve, we have shown 114 procedures are needed to achieve 80% completion rate in 35 min in majority of the fellows. Colorectal surgery fellows were observed to achieve screening colonoscopy competency approximately between 94 and 114 procedures. In the era of working time restrictions, prospective documentation of individual trainee performance may allow tailored training based on observed competency.Journal of Surgical Research 10/2011; 174(1):e17-23. · 2.25 Impact Factor -
Article: Loop ileostomy following anterior resection: is it really temporary?
[show abstract] [hide abstract]
ABSTRACT: A temporary loop ileostomy is often created to minimize the impact of peritoneal sepsis if anastomotic dehiscence occurs following low colorectal anastomosis. Although it has been suggested that a loop ileostomy should be reversed within 12 weeks of formation, this is often not the case. We set out to analyse the use of loop ileostomy following elective anterior resection in England and to identify factors associated with non and delayed reversal. Hospital episode statistics for the years 2001-2006 were obtained from the Department of Health. Patients undergoing elective anterior resection with a loop ileostomy for a primary diagnosis of rectal or recto-sigmoid cancer between April 2001 and March 2003 were identified as the study cohort. This cohort was followed until March 2006 to identify patients undergoing reversal of an ileostomy in an English NHS Hospital. A total of 6582 patients had an elective anterior resection between April 2001 and March 2003, of which 964 (14.6%) also had an ileostomy. Seven hundred and two (75.1%) patients were reversed before March 2006. Advancing age and comorbidity were statistically related to nonreversal. Median time to reversal was 207 days (Interquartile range 119-321.5 days). Postoperative chemotherapy and comorbidity significantly delayed reversal. One in four loop ileostomies performed to defunction an elective anterior resection is not reversed, and in the presence of significant comorbidity one in three is not reversed. Only 12% is reversed within 12 weeks.Colorectal Disease 03/2009; 12(5):428-32. · 2.93 Impact Factor -
Article: Effect of infliximab on short-term complications in patients undergoing operation for chronic ulcerative colitis.
[show abstract] [hide abstract]
ABSTRACT: Total proctocolectomy and ileal pouch anal anastomosis (IPAA) is the preferred operation for patients with chronic ulcerative colitis (CUC) refractory to medical therapy. Infliximab (IFX), an antitumor necrosis factor-alpha antibody, has demonstrated efficacy in medical management of CUC. The aim of this study is to determine if IFX before IPAA impacts short-term outcomes. A prospective institutional database was retrospectively reviewed for short-term complications after IPAA for CUC. Postoperative outcomes were compared between patients who received pre-IPAA IFX and those who did not. Between 2002 and 2005, 47 patients received IFX before IPAA, and 254 patients received none. There were no gender (p = 0.16) or body mass index (p = 0.07) differences between groups. IFX patients were younger than non-IFX patients (mean age 28.1 to 39.3 years) (p < 0.001). In IFX patients, 70% were receiving preoperative IFX, azathioprine, and corticosteroids. Mortality was nil. Overall surgical morbidity was similar: 61.7% and 48.8%, IFX and non-IFX, respectively (p = 0.10). Anastomotic leaks (p = 0.02), pouch-specific (p = 0.01) and infectious (p < 0.01) complications were more common in IFX patients. Multivariable analysis revealed IFX as the only factor independently associated with infectious complications (odds ratio [OR] = 3.5; CI, 1.6-7.5). In a separate analysis, incorporating age, high-dose corticosteroids, azathioprine, and severity of colitis, IFX remained significantly associated with infectious complications (OR = 2.7; CI, 1.1-6.7). CUC patients treated with IFX before IPAA have substantially increased the odds of postoperative pouch-related and infectious complications. Additional prospective studies are required to determine if IFX alone or other factors contribute to the observed increases in infectious complications.Journal of the American College of Surgeons 06/2007; 204(5):956-62; discussion 962-3. · 4.55 Impact Factor
