Ligation of intersphincteric fistula tract is an effective technique for the treatment of fistula in ano, including recurrent or unhealed fistula after other procedures. See Video Abstract at http://links.lww.com/DCR/A387.
Mortality after Hartmann's procedure for perforated diverticulitis has not decreased during the last 18 years. Morbidity has actually increased over time although this is related to increased disease severity and comorbidity. Future efforts should focus on the identification of patient subgroups benefiting from earlier elective surgery and alternative surgical approaches when perforated diverticulitis does occur.
Background and AimIn recent years, the incidence of colorectal cancer has been increasing, and it is now becoming the major cause of cancer death in Asian countries. The aim of the present study was to develop Asian expert‐based consensus to standardize the preparation, detection and characterization for the diagnosis of early‐stage colorectal neoplasia.MethodsA professional group was formed by 36 experts of the Asian Novel Bio‐Imaging and Intervention Group (ANBI2G) members. Representatives from 12 Asia–Pacific countries participated in the meeting. The group organized three consensus meetings focusing on diagnostic endoscopy for gastrointestinal neoplasia. The Delphi method was used to develop the consensus statements.ResultsThrough the three consensus meetings with debating, reviewing the literature and regional data, a consensus was reached at third meeting in 2016. The consensus was reached on a total of 10 statements. Summary of statements is as follows: (i) Adequate bowel preparation for high‐quality colonoscopy; (ii) Antispasmodic agents for lesion detection; (iii) Image‐enhanced endoscopy (IEE) for polyp detection; (iv) Adenoma detection rate for quality indicators; (v) Good documentation of colonoscopy findings; (vi) Complication rates; (vii) Cecal intubation rate; (viii) Cap‐assisted colonoscopy (CAC) for polyp detection; (ix) Macroscopic classification using indigocarmine spray for characterization of colorectal lesions; and (x) IEE and/or magnifying endoscopy for prediction of histology.ConclusionThis consensus provides guidance for carrying out endoscopic diagnosis and characterization for early‐stage colorectal neoplasia based on the evidence. This will enhance the quality of endoscopic diagnosis and improve detection of early‐stage colorectal neoplasia.
The echoendoscope is a feasible staging tool for colon cancer beyond rectum. However, accuracy of the echoendoscope needs to be verified by larger systematic studies.
Serrated lesions, especially sessile serrated adenoma/polyps (SSA/ P) are considered one of the most important precursors of colorectal cancers. However, it is still difficult to endoscopically differentiate SSA/P from hyperplastic polyps. In the present review, we mainly focus on the current status and future perspectives of endoscopic diagnosis of colorectal serrated lesions based on the results of a questionnaire survey and report from the Endoscopic Forum Japan (EFJ) 2015 held in Tokyo in August 2015. The proposed diagnostic strategy recommended for colorectal serrated lesions is as follows. (i) For detection, use of an updated image-enhanced endoscopy system including autofluorescence imaging (AFI) and narrow-band imaging (NBI) may be promising.(ii) For differential diagnosis (hyperplastic polyp or SSA/P) of diminutive, small and large serrated lesions, NBI with magnification and magnifying chromoendoscopy using both indigocarmine and crystal violet should be applied, respectively. (iii) For differential diagnosis of SSA/P (with or without cytological dysplasia), magnifying chromoendoscopy, endocytoscopy and updated AFI system modalities might be promising.
Long-term oncologic outcomes of colonic stenting as a "bridge to surgery" in patients with left-sided malignant colonic obstruction (LMCO) are unclear. This study was performed to compare long-term outcomes of self-expandable metal stent (SEMS) insertion as a bridge to surgery and emergency surgery in patients with acute LMCO. Methods: This retrospective cohort study included patients with acute LMCO who underwent SEMS insertion as a bridge to surgery or emergency surgery. The primary outcomes were 5-year disease-free survival (DFS), overall survival (OS), and recurrence rate. Survival outcomes were determined using the Kaplan-Meier method and compared using log-rank tests.Results: There was a trend of worsening 5-year OS rate in the SEMS group compared with emergency surgery group (45% vs. 57%, P = 0.07). In stage-wise subgroup analyses, a trend of deteriorating 5-year OS rate in the SEMS group with stage III (43% vs. 59%, P = 0.06) was observed. The 5-year DFS and recurrence rate were not different between groups. The overall median follow-up time was 58 months. On multivariate analysis, age of ≥ 65 years and American Joint Committee on Cancer stage of ≥ III, and synchronous metastasis were significant poor prognostic factors for OS (hazard ratio [HR],
Background and Aim
Self‐expandable metal stent (SEMS) is a favorable therapeutic option for patients with incurable malignant colonic obstruction (MCO). However, their long‐term efficacy and safety compared with those of stoma creation have not been well investigated. This study aimed to compare these long‐term outcomes between these two techniques in patients with incurable MCO.
Methods
This retrospective cohort included patients with incurable MCO with SEMS insertion (n = 105) and stoma creation (n = 97) between January 2009 and December 2019. The primary outcomes were patency after the procedure and 1‐year re‐intervention rates.
Results
The patency of the SEMS group was lower than that of the stoma group (88.9 vs 93.2% at 6 months, 84.1 vs 90.5% at 12 months, and 65.8 vs 90.5% at 18 months; log‐rank test, P = 0.024), but 1‐year re‐intervention rates were not different between the groups (10 vs 8%, P = 0.558). The median patency durations were 190 days for SEMS insertion and 231 days for stoma creation. Majority (84%) of SEMS patients did not require any re‐intervention until death. The early complication rate did not differ between the groups (P = 0.377), but SEMS insertion had fewer late minor complications than stoma creation (5 vs 22%, P = 0.001).
Conclusion
SEMS insertion is a safe and effective treatment for patients with incurable MCO. Although SEMS insertion had a lower patency than stoma creation, especially after 1 year, the 1‐year re‐intervention rates were not different, and SEMS durability was sufficient in most patients.
