Transanal hemorrhoidal dearterialization with mucopexy versus open hemorrhoidectomy in the treatment of hemorrhoids: a meta-analysis of randomized control trials
ConclusionsOur meta-analysis shows that THDm and OH are equally effective and can be attempted for the management of hemorrhoids. However, for THDm with Doppler guidance, more instruments and a longer operative time are required. Future large-scale, high-quality, multicenter trials with long-term outcomes are needed to prove these results and determine whether Doppler guidance in THD is truly necessary or not.

Clinical outcomes and case volume effect of transanal total mesorectal excision for rectal cancer: a systematic review
AbstractTransanal total mesorectal excision (TaTME) has been developed to improve quality of TME for patients with mid and low rectal cancer. However, despite enthusiastic uptake and teaching facilities, concern exists for safe introduction. TaTME is a complex procedure and potentially a learning curve will hamper clinical outcome. With this systematic review, we aim to provide data regarding morbidity and safety of TaTME. A systematic literature search was performed in MEDLINE (PubMed), EMBASE (Ovid) and Cochrane Library. Case reports, cohort series and comparative series on TaTME for rectal cancer were included. To evalu...

Surface anatomical landmarks for the location of posterior sacral foramina in sacral nerve stimulation
This study was conducted on 20 human cadavers. The cadavers were placed in a prone position, and all the soft tissues of the sacral region were removed to allow exposure of the osseous structures. Different measurements were taken in relation to the posterior sacral foramina, the posterior superior iliac spine (PSIS) and the median sacral crest (MSC). A median coefficient of variation (CV) was determined.ResultsThe diameter of the second sacral foramen showed the greatest variability. The distances between each individual foramen and the MSC had an acceptable variability (CV

Hubble trial: time to stick to basics for treatment of haemorrhoids?
Abstract The results of the Hubble trial, a randomised controlled trial comparing haemorrhoidal artery ligation with rubber band ligation for early-grade prolapsing haemorrhoids, are discussed. The difficulties in defining treatment success are debated along with the trial design highlighting the pitfalls of previous research. A finding that haemorrhoidal artery ligation is not necessarily superior to cheap alternatives has implications for current practice and future commissioning of surgeons.

Laparoscopic ventral rectopexy in male patients with external rectal prolapse is associated with a high reoperation rate
ConclusionsLaparoscopic ventral rectopexy is a safe surgical procedure in male patients with external prolapse. However, a high overall reoperation rate was noticed due to recurrent rectal and residual mucosal prolapse. This suggests that the ventral rectopexy technique should be modified or combined with other abdominal or perineal methods when treating male rectal prolapse patients.

Duhamel versus transanal endorectal pull through (TERPT) for the surgical treatment of Hirschsprung ’s disease
AbstractFor the surgical treatment of Hirschsprung ’s disease, several surgical techniques are used to resect the distal aganglionic colon. Two frequently used techniques are the Duhamel procedure and the transanal endorectal pull-through procedure. During the ‘8th Pediatric Colorectal Course’ in Nijmegen, November 2015, a workshop was organiz ed to share experiences of both techniques by several experts in the field and to discuss (long term) outcomes. Specifically, the objective of the meeting was to discuss the main controversies in relation to the technical execution of both procedures in order to mak...

AbstractBladder exstrophy is a rare malformation. Ureteral diversion, such as ureterosigmoidostomy or a neorectal bladder, has been described. When the patients reach adulthood, cancer may arise in these reconstructions. Our aim was to perform a systematic review (all languages) of the published literature on neoplasia after urinary diversion and suggested management in cases of cancer.

This study aimed to compare the anastomotic leak rates in patients undergoing compression anastomoses versus hand-sewn or stapled anastomoses. Randomized controlled trials (RCTs) comparing outcomes of compression versus conventional (hand-sewn and stapled) colorectal anastomosis were collected from MEDLINE, Embase and the Cochrane Library. The quality of the RCTs and the potential risk of bias were assessed. Pooled odds ratios (OR) were calculated for categorical outcomes and weighted mean differences for continuous data.

Day case robotic ventral rectopexy compared with day case laparoscopic ventral rectopexy: a prospective study
AbstractBackgroundVentral rectopexy to the promontory has become one of the most strongly advocated surgical treatments for patients with full-thickness rectal prolapse and deep enterocele. Despite its challenges, laparoscopic ventral rectopexy with or without robotic assistance for selected patients can be performed with relatively minimal patient trauma thus creating the potential for same-day discharge. The aim of this prospective case –controlled study was to assess the feasibility, safety, and cost of day case robotic ventral rectopexy compared with routine day case laparoscopic ventral rectopexy.MethodsBetween ...

Fistulas that fail to resolve may require surgery; however, fibrin glue therapy (FGT) may be a suitable alternative.MethodsWe retrospectively identified patients undergoing FGT for an abscess-associated enteric fistula between 2004 and 2015. Success was defined as closure of the fistula tract without need for additional intervention. A multivariable logistic regression analysis was utilized to identify f...

Biofeedback treatment of chronic constipation: myths and misconceptions
Abstract Chronic constipation is a prevalent disorder with considerable impact on healthcare costs and quality of life. Most patients would respond to conservative measures in primary care. Patients with refractory constipation are commonly referred to dedicated centers for appropriate investigations and management. After testing, three main subtypes of constipation are commonly identified: normal colon transit, slow transit, and functional defecation disorders. The etiology of functional defecation disorders is consistent with maladaptive behavior, and biofeedback therapy has been considered a valuable treatment option. ...
