Application of 4% formaldehyde under electronic colonoscope as a minimally invasive treatment of chronic hemorrhagic radiation proctitis / 世界急诊医学杂志（英文）

BACKGROUND@#To investigate the effectiveness of topical application of 4% formaldehyde as a minimally invasive treatment of rectal bleeding due to chronic radiation proctitis (CRP) under direct vision of electronic colonoscope.@*METHODS@#The clinical data of 13 CRP patients complicated with ≥ grade II bleeding admitted to our hospital between January 2003 and December 2018 were retrospectively analyzed. Under the guidance of electronic colonoscope, 4% formaldehyde combined with 5-aminosalicylic acid (5-ASA) suppositories was topically applied. Patients were followed up for two months after treatment, and the therapeutic effectiveness was observed and analyzed.@*RESULTS@#The rectal bleeding due to CRP was markedly reduced after topical application of 4% formaldehyde under colonoscope in all 13 patients. The bleeding stopped after one treatment session in 11 patients and after the second session in 2 patients. 5-ASA was also applied along with the use of 4% formaldehyde. The therapeutic effectiveness was satisfactory during the 1- and 2-month follow-up period.@*CONCLUSION@#Topical application of 4% formaldehyde under the direct vision of colonoscope as a minimally invasive treatment for CRB-induced bleeding is a simple, effective, affordable, and repeatable technique without obvious complications, which deserves further exploration and promotion.

Clinical study of hand-assisted laparoscopic total colectomy for colonic inertia / 中华外科杂志

<p><b>OBJECTIVE</b>To compare the efficacy of hand-assisted laparoscopic surgery (HALS) with that of open surgery (OS) in total colectomy, and to evaluate the feasibility of hand-assisted laparoscopic total colectomy for colonic inertia.</p><p><b>METHODS</b>A total of 42 patients of colonic inertia received total colectomy from January 2001 to June 2006 were randomly allocated to OS group (n = 22) and HALS group (n = 20). Data as clinical manifestation, perioperative features including operative time, intraoperative blood loss and incision length, postoperative features including first flatus-passing time, first fluid-feeding time, hospitalization time, early postoperative complications, and hospitalizing expense were recorded and compared in the two groups. Postoperative defecating frequency was followed up in both groups.</p><p><b>RESULTS</b>All patients underwent total colectomy successfully and no death of operation occurred. The clinical features, operative time and blood loss were similar for the two groups. Incision length, first flatus-passing time, first fluids-feeding time, hospitalization time were better in HALS group than those in OS group. But mean hospitalizing expense in HALS group was higher than that in OS group. One case of incision infection and one intestinal obstruction occurred in OS group. No complication occurred in HALS group. Patients were followed up for 2 - 14 months, in the meantime the average defecating frequency was 3.55 +/- 1.80/d.</p><p><b>CONCLUSIONS</b>HALS and open total colectomy are safe, rapid and effective surgical procedures for colonic inertia. HALS can result in a better cosmetic effect and a quicker postoperative recovery.</p>

The prognosis of the total proctocolectomy and ileal-pouch anal anastomosis / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the prognosis of the total proctocolectomy and ileal-pouch anal anastomosis (IPAA) for ulcerative colitis (UC) and familial adenomatous polyposis (FAP).</p><p><b>METHODS</b>Sixty-one patients with ulcer colitis or familial adenomatous polyposis were performed total proctocolectomy and ileal pouches-anal anastomosis during 1985 to 2002. There are S type pouch 25 cases, S-J type pouch 13 cases, J type pouch 17 cases and W type pouch 6 cases. The complication and function after the IPAA were also discussed.</p><p><b>RESULTS</b>No patient died after operation. The total morbidity is 16% (10/61), the morbidity of group UC (6/25) is higher than FAP's (4/34). The W type pouch's morbidity is higher than other three types', the operation with stapled technique is associated with fewer complication than hand-sewn IPAA (2/20 vs 8/41), however, there is also no significant difference between them. The number of stools per 24 hours is 4.2, the percent of the normal continence of daytime and nighttime is 84% (43/51) and 75% (38/51) respectively. There's only about 6% (3/51) patient with fecal incontinence. The most patients are satisfied with IPAA.</p><p><b>CONCLUSION</b>The proctocolectomy ileal pouch-anal anastomosis for FAP and UC has few complication with accepted frequency and preserve a good anal function, it is an ideal alternative approach.</p>
