Verification of blood flow path reconstruction mechanism in distal sigmoid colon and rectal cancer after high IMA ligation through preoperative and postoperative comparison by manual subtraction CTA.
INTRODUCTION
We aimed to investigate manual subtraction computed tomography angiography (MS-CTA) to further confirm the distribution and classification of LCA (left colic artery) ascending/descending branches, then observe the postoperative blood flow path to illustrate how the above branches evolved to postoperative blood path.
MATERIAL AND METHODS
89 patients with distal sigmoid and rectal cancer were referred in our observation and underwent MS-CTA between June 2020 and March 2022. We classified the distribution of LCA and confirmed whether there exists AMCA (accessory middle colic artery). Then we planned blood flow path based on the classification of LCA branches before operation. High ligation was applied in regular radical surgery. During operation, we carefully protect the bifurcation of ascending and descending LCA. Then we compared the planned blood flow path with the actual postoperative blood flow path to verify the mechanism we proposed previously.
RESULTS
Of 89 patients, 82 cases met our criteria, we summarized 6 distribution pattens of LCA ascending and descending branches. These preoperative pattens are consistent with the inspection during operation. The postoperative blood flow path of 6 pattens is evolved from the above adjacent anastomotic branches and is consistent with the planned blood flow path. We also found 2 cases with IMA stenosis and 1 case with SMA stenosis under pathological condition, and their compensatory blood flow path is in accordance with our theory. The rate of the anastomotic leakage in our study group is relatively low (7.3%).
CONCLUSION
MS-CTA could confirm the distribution of LCA and AMCA, display accurate postoperative blood reconstruction path after IMA high ligation, and it further verified the mechanism we proposed previously, which is the proximal anastomotic branches forming new blood flow path from high-pressure area to the low-pressure area. This mechanism might be helpful for performing accurate laparoscopic sigmoid and rectal cancer surgery.

Review
BACKGROUND
With the development of laparoscopic techniques and the broad clinical application of various anastomotic types, anal-preserving low anterior rectal resection and ultra-low anterior rectal resection have been popularized. Some patients with rectal cancer have retained their anus and improved their quality of life. Nevertheless, the incidence of postoperative anastomotic stenosis remains high, and anastomotic occlusion is even rarer.
CASE PRESENTATION
We report a case of anastomotic occlusion in a patient with rectal cancer, which occurred after undergoing laparoscopic low anterior rectal resection + prophylactic terminal ileal fistulation at our department. Under endoscopy, we used a small guidewire to break through the occluded anastomosis, thereby finding the lacuna. After endoscopic balloon dilation, digital anal dilatation, and continuous dilator-assisted dilation, the desired efficacy was achieved, ultimately recovering ileal stoma. Postoperative follow-up condition was generally acceptable, without symptoms like abdominal pain, bloating, or difficulty in defecation.
CONCLUSION
Numerous factors cause postoperative anastomotic stenosis in patients with rectal cancer. Complete occlusion of anastomosis occurs relatively rare in clinical practice, and is challenging to treat. This case was our first attempt to remove the anastomotic occlusion successfully, which avoided re-operation or pain from the permanent fistula.

Lymphogranuloma Venereum (LGV) is a notifiable disease linked to high-risk sexual practices such as cruising, chemsex, or orgies. The anorectal manifestation is associated with receptive anal sex and presents with characteristic symptoms such as proctitis, tenesmus, suppuration, and in advanced cases, anorectal fistulas or stenosis. The case of a 57-year-old man engaging in high-risk sexual practices is presented, showing symptoms such as discharge, fistulizations, rectal stenosis, and a weight loss of 15 kg. Following diagnostic studies, a neoplastic and inflammatory origin was ruled out, confirming the LGV diagnosis. Although the patient responded positively to a three-week course of doxycycline, the stenosis persisted, ultimately necessitating a terminal colostomy. The patient was scheduled to undergo a protectomy to control the inflammatory and infectious process, a procedure that took place months later without significant incidents. The primary treatment for LGV continues to be doxycycline. In cases of complications, such as fistulas, abscesses, or stenosis, surgical interventions, drainage, or pneumatic dilations may be necessary.

AIM
To assess the modifications in the technique of laparoscopic-assisted anorectal pull-through (LAARP) practiced at our institute and to analyze the postoperative outcome and associated complications.
MATERIALS AND METHODS
A retrospective study was done to analyze the results for LAARP procedure done for high anorectal malformations (ARMs) from January 2001 to May 2016. A total of 68 patients had undergone LAARP, with 62 male and 6 female children. Staged procedure was done in 55 patients and one child with rectovestibular fistula of 5 months of age had a single-stage procedure. Technical modifications such as traction over the fistula which helps in identification and dissection of the puborectalis muscle, dividing the fistula without ligation, railroading with Hegar's dilators over the suction cannula which creates adequate pull-through channel, have helped save time and make the procedure simpler. The patients were followed up with clinical evaluation and continence scoring.
RESULTS
All the patients withstood surgery well. One patient with rectovesical fistula required conversion to gain adequate length of the distal rectum, for whom the colostomy was closed and relocated at splenic flexure level. The complications were mucosal prolapse (8 cases), anal stenosis (5), adhesive obstruction (2), distal rectal necrosis (3), and urethral diverticulum (2). The progress has been satisfactory and weight gain is adequate. 71.15% patients had good continence on follow-up.
CONCLUSION
LAARP procedure is safe for high ARMs with good continence and correctable side effects. It has completely replaced posterior sagittal anorectoplasty procedure for high anomalies in our practice.

Rectal cancer is a worldwide disease whose incidence has increased significantly. Evidence-based medicine is a category of medicine that optimizes decision making by using evidence from well-designed and conducted research. Evidence-based medicine can be used to formulate a reasonable treatment plan for newly diagnosed rectal cancer patients. The current review focuses on the application of evidence-based treatment on patients with rectal cancer. The relationship between perioperative blood transfusion and recurrence of rectal cancer after surgery, the selection between minimally invasive laparoscopic surgery and traditional laparotomy, choice of chemotherapy for patients with rectal cancer prior to surgery, selection between stapled and hand-sewn methods for colorectal anastomosis during rectal cancer resection, and selection between temporary ileostomy and colostomy during the surgery were addressed. Laparoscopy is considered to have more advantages but is time-consuming and has high medical costs. In addition, laparoscopic rectal cancer radical resection is preferred to open surgery. In radical resection surgery, use of a stapling device for anastomosis can reduce postoperative anastomotic fistula, although patients should be informed of possible anastomotic stenosis.

PURPOSE
Rectal adenoma, a pre-cancerous lesion, is one of the indications for transanal endoscopic microsurgery (TEM). TEM has its unique advantages in the treatment of rectal adenomas. However, there are few reports on the therapeutic effects of large rectal adenoma (LRA). The objective of this study was to investigate the value of TEM in the treatment of LRA.
MATERIALS AND METHODS
We collected data from patients who underwent surgery at our center from 2007 to 2017. The postoperative pathology of all patients was rectal adenoma and the diameter of the adenoma was 3 cm or greater. Moreover, all patients underwent TEM. We followed up to observe the incidence of no wound healing, rectal stenosis and recurrence rate of rectal adenoma. The risk factors of adenoma recurrence and wound healing were analysed using single- and multiple-factor analysis.
RESULTS
The clinicopathological data of 85 patients with LRA were collected through a pre-set table. During the follow-up period, eight patients were lost to follow-up, and three (3.90%) patients developed rectal stenosis. After 2 years of post-operative follow-up, 20 (25.97%) patients had recurrence and 57 (74.03%) patients had no recurrence. Multivariate analysis showed that positive margin was an independent risk factor for recurrence of adenoma.
CONCLUSIONS
TEM is feasible in the treatment of large rectal tumours in Centers of Expertise with the technique.

Stapled hemorrhoidopexy (Longo operation) is a infrequent technique in our area. A different concept from hemorrhoidectomy, a proportionally important raise in cost and a special training may have contributed to it. We report our long-term results with the standard technique. The data of 35 patients with symptomatic second- and third-degree hemorrhoids who had stapled hemorrhoidopexy using a PPH03 stapler, from 01 January 2012 to 04 December 2020, were retrospectively collected. The sex ratio male: female was 3:4 and the mean age 45 (range 28-60) years. The follow-up consisted in a rectal exam and evaluated anatomical recurrence or prolapse. The mean operative time was 42 (30-70) min. The mean parenteral analgesic doses during the first 24 h were 1,52. The mean postoperative hospital stay was 1.55 (1-2) days. A single patient needed reoperation for a staple line bleeding, two patients had a thrombosis of internal hemorrhoids and in one patient a small prolapse was diagnosed at 3 months follow-up. No hematoma, anastomotic stenosis, persistent anal pain, tenesmus, or impaired anal continence was recorded. One patient mentioned discomfort related to the presence of staples. Patients were followed-up for 6 (1-9) years. Global satisfaction rate was 94%. Conclusion: Stapled hemorrhoidopexy procedure is a safe and feasible procedure, which necessitates few analgesics and allows an early discharge. A rigorous selection of cases and a correct surgical technique allow to obtain good long-term results and offer a high level of patients satisfaction.

Review
More than 80% of patients with Crohn's disease (CD) will require surgical intervention during their lifetime, with high rates of anastomotic recurrence and stenosis necessitating repeat surgery. Current data show that pharmacotherapy has not significantly improved the natural history of postoperative clinical and surgical recurrence of CD. In 2003, antimesenteric hand-sewn functional end-to-end (Kono-S) anastomosis was first performed in Japan. This technique has yielded very desirable outcomes in terms of reducing the incidence of anastomotic surgical recurrence. The most recent follow-up of these patients showed that very few had developed surgical recurrence. This new approach is superior to stapled functional end-to-end anastomosis because the stumps are sutured together to create a stabilizing structure (a "supporting column"), serving as a supportive backbone of the anastomosis to help prevent distortion of the anastomotic lumen due to disease recurrence and subsequent clinical symptoms. This technique requires careful mesenteric excision for optimal preservation of the blood supply and innervation. It also results in a very wide anastomotic lumen on the antimesenteric side. The Kono-S technique has shown efficacy in preventing surgical recurrence and the potential to become the new standard of care for intestinal CD.

International Journal of Clinical and... 2014To analyze the etiology and clinical diagnostic method for chronic complex anal and rectal inflammation in children less than 3 years old.
OBJECTIVE
To analyze the etiology and clinical diagnostic method for chronic complex anal and rectal inflammation in children less than 3 years old.
METHOD
Seven children (5 males and 2 females; 1 year 8 months to 3 years of age at the time of physician evaluation) with chronic complex anal and rectal inflammation were enrolled between May 2008 and May 2013 at our hospital. Clinical history, results of auxiliary examinations, and empirical treatment of the children were analyzed retrospectively combined with the etiologic diagnosis.
RESULTS
Four patients were confirmed to have Crohn's disease and one patient was confirmed to have intestinal tuberculosis; two patients were suspected to have Crohn's disease. Anemia and low pre-albumin level were common (seven patients); serologic testing revealed four patients with elevated IgG levels and seven patients with elevated IgA levels; there were no patients with positive tuberculosis antibody titers and two patients were weakly positive for C-ANCA (one patient with Crohn's disease and one patient intestinal tuberculosis). Colonoscopies revealed that the entire colon was affected in one patient, the left hemicolon was affected in four patients, and the sigmoid colon and rectum were affected in two patients. Two patients with Crohn's disease and one patient with intestinal tuberculosis were diagnosed by colonoscopies in combination with histopathologic examinations. Two patients with Crohn's disease were confirmed after empirical drug treatment, and two other patients were not definitely diagnosed.
CONCLUSION
The possibility of Crohn's disease or intestinal tuberculosis should be considered in the clinical diagnosis of complex chronic anal and rectal inflammation in younger children. Local surgery is sometimes unnecessary. Empirical drug treatment should be used if necessary.
