Summary: This study compared the effectiveness of osteopathy and biofeedback in the treatment of dyssynergic defecation. The short-term results showed both treatments were effective, with some differences observed between the two. Long-term follow-up results indicated that osteopathy has promising long-lasting effects in treating dyssynergic defecation.

Summary: This study compared the changes in Rintala scores in children with FC and ODS managed by BT injection, BMP, and SBL, versus a control group managed by only BMP and SBL. The results showed no statistically significant difference between the two groups, indicating that BT injection did not provide additional improvement in defecatory function when assessed by Rintala score.

Summary: This study aimed to evaluate the characteristics of women with obstructed defecation syndrome and radiographic rectoceles, and to analyze the relationship between anatomical abnormalities and dysfunction. The results showed that women with posterior vaginal wall prolapse had larger rectoceles on defecography and were more likely to splint during defecation.

Summary: This study analyzed consecutive patients who underwent ventral mesh rectopexy for rectal prolapse or obstructed defecation and found that redundant colon and pre-existing constipation are risk factors for postoperative constipation persistence or new-onset, with postoperative pelvic floor rehabilitation potentially reducing this risk.

Summary: Botulinum toxin significantly decreases anal basal pressure when preinjection pressure is higher than 70 mmHg. Factors such as preinjection pressure, rectal washouts, patients' weights, and sex contribute significantly to pressure changes.

Summary: Rectal prolapse patients exhibit varying symptom severity and healthcare utilization based on age. Older patients are more likely to report bothersome symptoms of pain and bleeding, while younger patients are more likely to experience obstructed defecation syndrome. Most patients report mucus discharge, but only a minority find it bothersome.

Summary: The study evaluated the trends in surgical management of obstructed defecation syndrome (ODS) over a 10-year period in Italian referral centers. The data showed that surgical techniques varied depending on the clinical scenarios and sphincter function. The complexity of ODS treatment was highlighted by the changing trend in surgical management over time.

Summary: The aim of this study was to determine the prevalence of obstructed defecation syndrome (ODS) among patients who underwent hemorrhoidectomy and to assess the correlation between preoperative constipation score and postoperative patients' satisfaction. The study included 120 patients, and 24.2% of them had obstructed defecation. The postoperative constipation score significantly improved and had a negative correlation with preoperative total constipation score. Therefore, routine preoperative measurement of ODS is recommended for patients who need further evaluation and counseling.

Summary: This retrospective study aimed to evaluate the diagnostic performance of MR defecographic findings in the diagnosis of dyssynergic defecation (DD). The results showed significant differences in several parameters between the DD and non-DD groups, including anorectal angle (ARA) and M line at rest, defecation, and change between 2 phases, anal canal width, prominent puborectalis muscle, and abnormal evacuation. Multivariate logistic regression revealed that M line at defecation and ARA at defecation were significant findings in differentiating between DD and non-DD. The study concludes that MR defecography has high diagnostic performance in DD diagnosis. Rating: 8 out of 10.

Summary: Anismus or non-relaxing puborectalis muscle (PRM) can affect over 40% of patients with obstructed defecation (OD). Management options include biofeedback, botulin toxin injection, or partial puborectalis muscle myotomy. A modified surgical technique can be used to avoid complications such as bleeding and rectal injury.

Summary: Dyssynergic defecation (DD) is commonly associated with chronic constipation. This study aimed to evaluate the effectiveness of botulinum neurotoxin (BoNT) in treating DD through a systematic review and meta-analysis. The results showed that BoNT injection provided short-term symptom improvement in DD patients, but the effect decreased after 12 months. BoNT injection was not significantly different from surgery in terms of effectiveness, complications, and symptom recurrence, but it carried a higher risk of fecal incontinence compared to biofeedback therapy.

Summary: Defecation is a complex physiological process relying on intricate mechanisms involving the autonomic and somatic nervous system, pelvic floor muscles, and anal sphincter complex. Anorectal dysfunction can lead to constipation, a bothersome disorder that significantly impacts the daily lives of children and their families. This review focuses on different mechanisms underlying anorectal dysfunction and specific treatment options for improving defecation dynamics in children with functional constipation.

Summary: This systematic review and meta-analysis aimed to examine the relationship between the type, approach, and timing of colectomy and the risk of Desmoid tumors (DT) in patients with familial adenomatous polyposis (FAP). The results indicate that the current literature does not provide conclusive evidence regarding the impact of colectomy type, approach, or timing on DT risk in FAP patients.

Summary: Transanal total mesorectal excision (TaTME) was developed as a solution for problems encountered in pelvic surgery, especially for rectal cancer. The transanal approach overcomes access and visualization issues faced with a pure abdominal approach. In experienced hands, TaTME can successfully address challenges in anatomically complex rectal cancer patients and complement abdominal surgery.

Summary: This review with pooled analysis aimed to determine the incidence of dehydration-related and all-cause readmissions after formation of an ileostomy, and the associated costs. The study found that one in five patients are readmitted within 30 days of ileostomy creation, with dehydration being the leading cause. These readmissions come with high healthcare costs.

Summary: The objective of this study was to examine whether variation in failure to rescue (FTR) contributes to differences in mortality between centres and over time for patients undergoing colorectal cancer surgery. The study found that high-mortality centres were characterized by higher rates of FTR and postoperative complications, and the improvement in FTR over the past decade was the main factor driving the decrease in mortality.

Summary: This study examined the readmission rates after colorectal cancer surgery in New Zealand and identified the risk factors and clinical reasons for unplanned readmissions. The rates of readmission were high and did not significantly improve over time, mainly due to comorbidities, advanced disease, and postoperative complications.

Summary: This study reports the incidence and outcomes of major thoracic trauma and rib fractures in New Zealand. The results show that transport-related injuries are the predominant mechanism, and the incidence of these injuries has increased over time. To improve care for major trauma patients with rib fractures, national guidelines and robust referral pathways should be considered.

Summary: This study investigated the practice of cholecystectomy in New Zealand and found significant variations in the rates of index and elective cholecystectomy. These variations were not adequately explained by patient, operative, or hospital factors alone. Therefore, national quality improvement efforts are needed to standardise the availability of cholecystectomy.

Summary: This study examines the survival and recurrence of patients with small intestinal neuroendocrine neoplasms (SI-NENs) in Auckland, New Zealand. The study finds that the stage at diagnosis is associated with survival, but resection of the primary tumor or distant metastasis does not provide a significant survival benefit for patients with stage IV disease. However, patients with stage I or II disease have no recurrence after complete resection.
