Colonic J pouch neo‑rectum versus straight anastomosis for low rectal cancers.

AIM: The development of sphincter saving procedures for low carcinoma rectum has been the consequence of oncological and technological factors. The major disadvantage associated with these procedures is the development of anterior resection syndrome because of the resection of rectal reservoir. Colonic J pouch (CJP) neorectum has been practiced as an antidote to overcome this problem. We are working at a tertiary care center, which is a high volume center for rectal cancers. We thought it worthwhile to assess the efficacy of J Pouch neorectum viz.‑a‑viz. a straight coloanal anastomosis for low rectal cancers. MATERIALS AND METHODS: Hospital based prospective randomized study (June 2007‑December 2009) low rectal cancers (4‑12 cm from the anal verge). One group (20 patients) subjected to low/ultralow anterior resection with straight anastomosis (SA) and other group (22 patients) to CJP. The two groups were compared on the basis of functional outcome. RESULTS: Anastomotic leak, strictures, frequency of bowel movements, nocturnal bowel movements, use of retarding medication and incontinence to solids, liquids and gases were seen more in SA group. All these findings were statistically significant. CONCLUSIONS: We conclude that CJP has a significant functional advantage over SA and improves the overall quality‑of‑life in patients of low rectal cancers and the advantage persisted over a period of more than 30 months.

Comparison of a Straight, a Coloplasty, and a Colonic J-pouch Anastomosis after a Proctectomy for Rectal Cancer

PURPOSE: Colonic pouches have been used to improve the reservoir function of the neorectrum after a ultra-low anterior resection for treatment of rectal cancer. The purpose of this study was to compare the safety and the functional outcome between a straight anastomosis, an anastomosis using coloplasty, and that using a colonic J-pouch in patients who had undergone an ultralow anterior resection. METHODS: From 2004 through 2006, 60 patients underwent a coloanal straight (straight group: n=23), coloplasty (coloplasty group: n=19), or colonic J-pouch (J-pouch group: n=18) anastomosis to the anal canal after a total mesorectal excision of the rectal cancer. We retrospectively reviewed the medical records of those patients for clinical outcomes according to the reservoir type. The median follow-up interval was 23.7 (4.4-40.9) mo. RESULTS: The anastomotic leakage rate was higher in the coloplasty group (21.1%) than in the straight group (8.7%) or in the J-pouch group (0%), but the difference was not significant (P=0.1). The mean number of bowel movements per day was significantly lower in the coloplasty group (3.6) and in the pouch group (3.1) than in the straight group (6.2) (P=0.015). No statistically significant differences were found among the three groups regarding other functional outcomes, including use of antidiarrheal drugs (P=0.971), gas incontinence (P=0.256), fecal incontinence (P=0.544), use of pads (P=0.782), difficulty of evacuation (P=0.496), and use of enemas (P=0.712). CONCLUSION: Reconstruction with a coloplasty or a colonic J-pouch in patients undergoing a low colorectal or coloanal anastomosis after rectal cancer surgery seems to decrease the number of daily bowel movements compared to a straight anastomosis. However, the anastomotic leakage rate of coloplasty group was higher than that of the straight-anastomosis group.

Application of sigmoid coloplasty after resection of middle or low rectal cancer / 中华消化外科杂志

Objective To investigate the feasibility of sigrnoid coloplasty for patients after resection of middle or low rectal carcinoma, and to evaluate the defecation function after the operation. Methods Forty-three patients with middle or low rectal cancer who had been admitted to the cancer Hospital of the Chinese Academy of Medical Sciences from January 2007 to January 2008 received sigrnoid coloplasty after rectal carcinoma resection (treatment group), and another 43 patients who had been admitted during the same period received colonic J pouch reconstruction (control group). The feasibility and safety of the 2 surgical procedures and postoperative defecation function were assessed. All data were processed by t test, chi-square test or Fisher exact probability. Results The sigmoid coloplasty was successfully performed in all patients in treatment group, while the reconstruction of the J pouch failed in 4 patients in the control group. Three patients in each group underwent temporary transverse colostomy. The incidences of postoperative complications in treatment group and control group were 7% (3/43) and 9% (4/43), respectively, with no statistical difference between the 2 groups (X2 =0. 282, P > 0.05). The median frequency of defecation in treatment group was 2.0 ± 1.5 per 24 hours, which was significantly less than 2.5 ± 1.0 in control group (X2 = 1. 242, P > 0.05). The fecal incontinence scores in treatment group and control group were 1.7 ± 0. 7 and 1.6 ± 0.8, respectively, with no statistical difference between the 2 groups (t = 0. 285, P > 0. 05). Conclusion Sigmoid coloplasty has similar benefits to colonic J pouch reconstruction, while sigmoid eoloplasty is relatively feasible, effective and safe for low colorectal or coloanal anastomosis.

Functional Outcome after Ileal J-pouch Anal Anastomosis in Patients with Ulcerative Colitis

PURPOSE: This study was performed to assess the complications and functional outcomes after a total proctocolectomy and ileal J-pouch anal anastomosis for patients with ulcerative colitis. METHODS: We reviewed the medical records of 30 patients who had undergone a total proctocolectomy and ileal J-pouch anal anastomosis for ulcerative colitis from 1992 to 1999 in our hospital. We used questionnaires or telephone interviews to assess the functional outcomes of the patients. The median duration of follow-up was 23 months after the ileostomy take down. RESULTS: The mean age of the patients at the definitive operation was 35.9 (+/-11.8). The indications for operation were medical intractability (76.7%), suspicious malignancy (13.3%), perforation (6.7%), and hemorrhage (3.3%). The double stapling method was used in 26 patients and the handsewn method in 4 patients. Of the 30 patients, 23 patients completed the functional analysis. Bowel frequency was 6.6 (+/- 2.6) per 24 hours, with 5.1 (+/- 2.1) in the daytime and 1.4 (+/-1.3) in the night. Fourteen patients (60.9%) had relatively mild incontinence, and four patients (17.4%) had to wear pads, especially at night. Eighteen patients (78.3%) were able to discriminate flatus from feces, and only one patient (4.3%) suffered from perianal irritation. Twelve patients (52.2%) had to restrict their diets, and five patients (21.7%) took antidiarrheal medications. Pouchitis occurred in three patients (13.0%). Sexual dysfunction was noted in four patients (17.4%), and urinary urgency in one patient (4.3%). There was no functional difference between the double stapling method and the handsewn method. CONCLUSIONS: The functional outcomes after ileal J-pouch anal anastomosis for patients with ulcerative colitis were satisfactory, irrespective of the method of anastomosis.

Clinical and Physiologic Anorectal Function after Low Anterior Resection in Patients with Rectal Cancer: A Prospective Randomized Comparison of Straight and Colonic J-Pouch Anastomoses

PURPOSE: The aim of this prospective study was to analyze anorectal physiologic and clinical outcomes of the colonic J-pouch-anal anastomosis compared with the traditional straight colorectal anastomosis after ultra-low anterior resection in patients with rectal cancer, thus to define if this method of modified reconstruction has a functional superiority. METHODS: After total mesorectal excision for mid or low rectal cancers, patients were randomized to either a straight (n=23) or a colonic J-pouch anastomosis (n=24) to the lowermost rectum or anal canal. Functional outcomes were compared between two groups using an anorectal manometry performed before and 1 year after surgery and a bowel function questionnaire administered 6 months and 1 year postoperatively. RESULTS: Except the arithmetic level of anastomosis which was significantly higher in straight group than in pouch group (5.1 +/- 1.2 cm vs. 3.8 +/- 0.9 cm; P=0.0001), the two groups were well matched for demographic distribution, pathologic stage, colonic segment used for neorectum and use of adjuvant therapies. Patients with colonic J-pouch anastomosis showed functional superiority in terms of frequency of bowel movements, degree of urgency at 6 months (P<0.0001 and =0.03, respectively) and 1 year postoperatively (P<0.0001 and <0.05, respectively). Functional parameters, including incontinence to liquid stool and impaired discrimination between gas and stool were more pronounced in straight group after 6 months (P=0.04, and <0.05, respectively), but the differences were not statistically significant after 1 year. Sensation of incomplete evacuation was not different statistically between groups at 6 months, but more common in J-pouch group at 1 year (39.1% vs. 8.3%; P=0.04). As well as the length of high pressure zone and presence of rectoanal inhibitory reflex, there was no difference in sphincter pressure parameters between groups either before or 1 year after surgery. Maximal tolerable volume of the neorectum in J-pouch group was 110.2 +/- 16.7 ml, which was significantly larger than that of 74.1 +/- 14.9 ml in straight group (P<0.0001), and the neorectum in J-pouch group was significantly more compliant than that in straight group (6.1 +/- 1.9 vs. 3.3 +/- 2.1; P<0.0001) in 1 year after surgery. CONCLUSIONS: Construction of a colonic J-pouch as a substitute for the rectum restores neorectal volume and compliance. Clinically it offers patients superior anorectal function compared with straight anastomosis. To minimize evacuation difficulty associated with the pouch, optimal size of the pouch should be defined, thus to achieve an ideal balance between stool frequency/urgency and evacuation problems through larger prospective studies.

Restorative Proctocolectomy: Operative Safety and Functional Outcomes

PURPOSE: The restorative proctocolectomy has been accepted as the operation of choice for chronic ulcerative colitis and familial adenomatous polyposis. The purpose of this study was to assess the operative safety and the functional outcome after a total proctocolectomy and ileal-pouch anal anastomosis. METHODS: The medical records of 16 patients who had undergone a total proctocolectomy and ileal-pouch anal anastomosis for ulcerative colitis (n=9) and familial adenomatous polyposis (n=7) from January 1996 to December 1999 were reviewed. The mean length of follow-up was 19.9 months, and we evaluated functional outcome using a prepared questionnaire. RESULTS: A hand-sewn anastomosis with diverting ileostomy was performed in 9 patients, and a double stapled anastomosis was done in 7 patients. Postoperative complications occurred in 8 cases (50%): intestinal obstructions in 4 patients and anastomosis related complications in 4 patients, i.e. stenosis (n=2), leak (n=1) and perianal abscess (n=1). The defecation frequency and the, day and night continence were improved in the first period (one year after surgery) compared to the second period (3 months after surgery). The need for anti-diarrheal medication, and for the use of a pad was also decreased in the second period compared to the first period. Postoperative urinary function was satisfactory in 13 of 14 patients. Postoperative sexual function was assessed in 8 patients (5 males, 3 females) and showed in good erection (5/5), ejaculation (5/5), and satisfactory sexual life (8/8). CONCLUSION: Satisfactory functional outcomes regarding the frequency of bowel movement and fecal incontinence and operative safety can be achieved after a restorative proctocolectomy for chronic ulcerative colitis and familial adenomatous polyposis.

Restorative proctocolectomy: operative safety and functional outcomes

Restorative proctocolectomy (total proctocolectomy and ileal J pouch anal anastomosis) has been accepted as the operation of choice in the setting of chronic ulcerative colitis and familial adenomatous polyposis. The purpose of this study was to assess operative safety and functional outcome after restorative proctocolectomy. A total of sixteen patients underwent surgery between January 1996 and December 1999. Hand sewn anastomosis with diverting ileostomy was performed in 9 patients and double stapled anastomosis in 7 patients. The underlying disease was ulcerative colitis in 9 cases and familial adenomatous polyposis in 7. Postoperative complications developed in 8 cases (50%), and intestinal obstruction was found in 4 cases (2 cases were operated upon). Anastomosis related complications were stenosis (n=2), leak (n=1) and perianal abscess (n=1). All patients were followed up at the outpatient clinic using questionnaires, with a mean follow up period of 19.9 months. The frequency of bowel movement was 8.2 per day in hand sewn anastomosis (HS), and 12 per day in double stapled anastomosis (DS) 3 months after surgery (period 1). This frequency decreased to 5.5 per day in HS, and 4.6 per day in DS after one year (period 2). Day and night continence was shown in 12/15, and 5/15, respectively in period 1, but improved to 10/11, and 10/11, respectively in period 2. Night time incontinence was noted in 10 of 15 patients in period 1 (seepage 3/15, soiling 7/15). The need to take anti-diarrheal medication, and to use a pad was noted in 2/15, and 10/15, respectively in period 1, but no patient took antidiarrheal medication or wore a protective pad in period 2. Postoperative urinary function was satisfactory in 13/14 patients. Postoperative sexual function was analyzed in a total of 8 patients, who showed good erection (5/5), ejaculation (5/5) and satisfactory sexual life (5/5). In females, 3 patients showed a satisfactory sexual life. In conclusion, restorative proctocolectomy for chronic ulcerative colitis and familial adenomatous polyposis can be performed safely with excellent functional outcomes, including bowel movement, urinary and sexual functions one year after surgery.
