Botulinum Toxin Injection for Analgesic Effect after Hemorrhoidectomy: A Randomized Control Trial.

Objectives: Hemorrhoid is a common disease in surgical practice, but only a few numbers of patients need surgical treatment. The most common concern of patients is postoperative pain. This study aimed to evaluate the efficacy and safety of an intersphincteric injection of botulinum toxin for post-hemorrhoidectomy pain relief.

Bridging metallic stent placement in acute obstructed left sided malignant colorectal cancer: optimal time for surgery.

Background: Colonic stenting is now the preferred treatment either for palliation or as a bridge to surgery for obstructed colorectal cancer. It reduces complications from emergency surgery and the need for colostomy formation. However, stent perforation can lead to peritoneal tumor spillage, a higher rate of infection and changing the risk of a potentially curable disease to an incurable one.

Ligation of intersphincteric fistula tract and its modification: Results from treatment of complex fistula.

Aim: To compare healing rates between intersphincteric fistula tract (LIFT) and LIFT plus partial fistulectomy procedures.

Methods: A study of complex fistula-in-ano patients was carried out from 1(st) March 2010 to 31(th) January 2012. All operations were done by colorectal surgeons at a referral center in a Ministry of Public Health hospital.

Single-access laparoscopic rectal surgery is technically feasible.

Introduction. Single-access laparoscopic surgery (SALS) has been successfully introduced for colectomy surgery; however, for mid to low rectum procedures such as total mesorectal excision, it can be technically complicated. In this study, we introduced a single-access technique for rectum cancer operations without the use of other instruments.

Clinicopathological characteristics of mucinous and non-mucinous adenocarcinoma in the colon and rectum in Rajavithi Hospital, Thailand.

Background: The clinicopathological characteristics of colorectal mucinous adenocarcinoma (MA) are still controversial. Most of the reports suggested that MA were associated with worse clinicopathological behavior and poorer prognosis than non-mucinous adenocarcinoma (NMA) while the others showed no difference.

Objective: To compare clinicopathological characteristics and tumor recurrence of MA patients with those in NMA patients.

Core out fistulectomy, anal sphincter reconstruction and primary repair of internal opening in the treatment of complex anal fistula.

Objective: To determine the surgical technique "core out fistulectomy with anal sphincter reconstruction and primary closure of internal opening" in the treatment of trans-sphincteric fistula (high type or long tract) or supra-sphincteric fistula in terms of fistula healing, morbidity, recurrence and anal continence.

Material And Method: Between January 2004 and December 2005, 33 patients were enrolled in the present study. There were 30 males and 3 females with median age 42 (range 19-73) years.

Preoperative capecitabine with pelvic radiotherapy for locally advanced rectal cancer (phase I trial).

Objective: Phase I multicenter study defined the maximal tolerated dose (MTD), dose-limiting toxicity (DLT) and safety profile of capecitabine in combination with preoperative radiation for patients with locally advanced rectal cancer (LARC).

Material And Method: Patients were treated with oral capecitabine (700, 800, 900, 1000, 1100 and 1200 mg/m2 twice daily continuously) plus preoperative whole pelvic irradiation (45-46 Gy in 23-25 fractions over 5-6 weeks). Surgery was performed at the median of 42 days after chemoradiation treatment.
