Meta-Analysis
Stag Beetle Knife (SB Knife) is increasingly being utilized for Zenker's Diverticulectomy (ZD). Our study assessed the effectiveness and safety of the SB Knife for the management of ZD. Ovid EBM reviews, Ovid Embase, Ovid Medline, ClinicalTrials.gov, Scopus, and Web of Science were searched to identify studies that utilized SB knife for ZD. Pooled proportions (PP) were calculated using the random-effects model. Heterogeneity was evaluated using I2 statistics. A total of 7 studies with 268 patients were included in the final analysis. Dysphagia and regurgitation were the most common clinical symptoms. The mean size of the ZD was 2.8 ± 0.7 cm and 28 (of 148) patients had undergone previous treatments. The PP of technical success was 98% (95% CI: 92.3-99.5; I20) with a mean procedure duration of 26.2 ± 8.3 minutes. The PP of clinical response at first follow-up and relapse after index procedure was 87.9% (95% CI: 81.6-92.3; I219) and 13.5% (95% CI: 9.6-18.6; I22), respectively. At final follow-up, the PP of clinical remission was 96.2% (95% CI: 91-98.4; I230.6) while the PP of procedure failure was 3.6% (95% CI: 1.6-8.1; I20). No severe adverse events (AEs) were noted while using the SB Knife. However, the PP of intraprocedural and postprocedural AEs was 13.2% (95% CI: 9.6-17.8; I20) and 9.3% (95% CI: 5.7-14.9; I2 < 20.9), respectively. SB Knife is highly safe and effective for Zenker's Diverticulectomy with a failure rate of only 3.6%.

BACKGROUND
Meckel's diverticulum is present in about 2% of the population. The literature reports 3.2% incidence of tumors within Meckel's diverticulum; the tumors are predominantly benign.
OBJECTIVE AND METHODS
The purpose of this study was to evaluate malignant tumors in Meckel's diverticulum through systematic review of the literature and review of electronic medical records including pathology reports over 14 years at the Mayo Clinic, Rochester, USA.
RESULTS
A literature review over the last 10 years identified 37 citations with 402 patients (median age: 58 years; 68.9% males). The predominant malignancy reported was neuroendocrine tumor 84.6%, followed by gastrointestinal stromal tumor 8.2%, and adenocarcinoma 6%. At the time of diagnosis, 29.5% of patients had metastases. In the Mayo Clinic electronic medical records review, there were 19 patients (5.1% of them surgically removed Meckel's diverticulum) who had a malignancy associated with Meckel's diverticulum: 63.2% neuroendocrine tumor, 10.5% gastrointestinal stromal tumor, 5.3% adenocarcinoma, 5.3% pancreatic epithelial neoplasia, and 15.8% metastases from secondary location. Median size of the malignancy was 7 mm, and 17/19 malignancies were coincidental findings. Most neuroendocrine tumors infiltrated the submucosa, while gastrointestinal stromal tumor and adenocarcinoma invaded the serosa. At the time of diagnosis, 33.3% of patients had metastases.
CONCLUSION
About 5% of Meckel's diverticulums resected were associated with malignant tumors, most commonly neuroendocrine tumor, and a significant portion of Meckel's diverticulum malignancy was metastatic at the time of discovery.

Review
BACKGROUND
Primary choledocholithiasis (PC) is a common disease in biliary surgery. The treatment is always challenging due to its high recurrence. A systemic review is undertaken to determine the risk factors for recurrence and provide with the individualized management strategy.
METHODS
Electronic databases PubMed (Medline), Embase and Cochrane Central Register of Controlled Studies were searched for relevant articles on risk factors for PC recurrence. Its therapeutic intervention was also collected and analysed.
RESULTS
A total of 36 articles were eligible for inclusion. The recurrent risk factors include abnormalities of biliary anatomy (peripapillary diverticulum), dynamics (choledochal dilation, sharp angulation and stone number), metabolism (advanced age and hypothyroidism) and bacterial infection (Enterobacter and Helicobacter pylori). These factors eventually induce cholestasis and stone formation. At present, there is no guideline and expertise consensus for PC management. The treatment mainly consists of stone retrieval approaches and internal drainage surgeries. The former are minimally invasive methods: endoscopic sphincterotomy (EST), papillary balloon dilation (EPBD) and laparoscopic common bile duct exploration (LCBDE). The latter include choledochoduodenostomy (CDS) and choledochojejunostomy (CJS) with Roux-en-Y reconstruction. By far, the internal drainage surgeries have significantly lower recurrence than stone retrieval approaches.
CONCLUSION
Abnormal biliary anatomy, dynamics, metabolism and bacterial infection are the risk factors for PC. Both EST/EPBD and LCBDE can be performed as initial treatment. For recurrent PC, CDS is more suitable to the elderly, while Roux-en-Y CJS reserves for young patients or those in good conditions.

Meta-Analysis Review
BACKGROUND
Zenker's peroral endoscopic myotomy (Z-POEM) has revolutionized the therapeutic strategy for Zenker's diverticulum (ZD) with promising results. We conducted this meta-analysis to estimate the safety and efficacy of Z-POEM for ZD and compare the feasibility and effectiveness of Z-POEM with that of flexible endoscopic septotomy (FES).
METHODS
A comprehensive literature search was conducted in PubMed, EMBASE, Web of Science, and Cochrane Library databases to query for studies that assessed the safety and efficacy of Z-POEM for ZD. All articles published from inception to July 31, 2021 were included. The primary outcomes were the overall technical success rate, clinical success rate, incidence of adverse events, and clinical recurrence rate.
RESULTS
Eleven studies involving 357 patients undergone Z-POEM were included. Overall, the quality of included studies was above average, with five studies rated as high quality and six ranked as moderate quality. The overall pooled technical success rate for Z-POEM was 96.3% (95% confidence interval [CI] 93.6-97.9%; I = 0%). The total pooled clinical success rate for Z-POEM was 93.0% (95% CI 89.4-95.4%; I = 0%). The pooled incidence of adverse events for Z-POEM was 12.4% (95% CI 9.1-16.7%; I = 0%). The pooled clinical recurrence rate for Z-POEM was 11.2% (95% CI 7.6-16.2%; I = 0%). The clinical success for Z-POEM was significantly better than that of FES (relative risk [RR]: 1.11; CI 95% 1.03-1.18; p = 0.004, I = 0%), while there were no significant differences in technical success, adverse events, and clinical recurrence between Z-POEM and FES.
CONCLUSION
Z-POEM could be an effective and safe therapeutic modality for ZD, and even has a slightly higher clinical success rate than FES. However, comparative studies with long-term follow-up will be needed to further confirm our finding.

Review
AIM
To investigate the clinical presentation, diagnosis, and treatment of giant colonic diverticulum (GCD, by means of a complete and updated literature review). GCD is a rare manifestation of diverticular disease of the colon. Less than 200 studies on GCD were published in the literature, predominantly case reports or small patient series.
METHODS
A systematic review of the literature was performed using the Embase and PubMed databases to identify all the GCD studies. The following MESH search headings were used: "giant colonic diverticulum"; "giant sigmoid diverticulum". The "related articles" function was used to broaden the search, and all of the abstracts, studies, and citations were reviewed by two authors. The following outcomes were of interest: the disease and patient characteristics, study design, indications for surgery, type of operation, and post-operative outcomes. Additionally, a subgroup analysis of cases treated in the last 5 years was performed to show the current trends in the treatment of GCD. A GCD case in an elderly patient treated in our department by a sigmoidectomy with primary anastomosis and a diverting ileostomy is presented as a typical example of the disease.
RESULTS
In total, 166 GCD cases in 138 studies were identified in the literature. The most common clinical presentation was abdominal pain, which occurred in 69% of the cases. Among the physical signs, an abdominal mass was detected in 48% of the cases, whereas 20% of the patients presented with fever and 14% with abdominal tenderness. Diagnosis is based predominantly on abdominal computed tomography. The most frequent treatment was colic resection with en-bloc resection of the diverticulum, performed in 57.2% of cases, whereas Hartmann's procedure was followed in 11.4% of the cases and a diverticulectomy in 10.2%. An analysis of sixteen cases reported in the last 5 years showed that the majority of patients were treated with sigmoidectomy and en-bloc resection of the diverticulum; the postoperative mortality was null, morbidity was very low (1 patient was hospitalized in the intensive care unit for postoperative hypotension), and the patients were discharged 4-14 d after surgery.
CONCLUSION
Giant colonic diverticulum is a rare manifestation of diverticular diseases. Surgical treatment, consisting predominantly of colonic resection with en bloc resection of the diverticulum, is the preferred option for GCD and guarantees excellent results.

Meta-Analysis Review
BACKGROUND
Oesophageal diverticula are rare outpouchings of the oesophagus which may be classified anatomically as pharyngeal (Zenker's), mid-oesophageal and epiphrenic. While surgery is indicated for symptomatic patients, no consensus exists regarding the optimum technique for non-Zenker's oesophageal diverticula. The aim of this study was to determine the outcome of surgery in patients with non-Zenker's oesophageal diverticula.
METHODS
PubMed, MEDLINE and the Cochrane Library (January 1990 to January 2016) were searched for studies which reported outcomes of surgery in patients with non-Zenker's oesophageal diverticula. Primary outcome measure was the rate of staple line leakage.
RESULTS
Twenty-five observational studies involving 511 patients (259 male, median age 62 years) with mid-oesophageal (n = 53) and epiphrenic oesophageal (n = 458) diverticula who had undergone surgery [thoracotomy (n = 252), laparoscopy (n = 204), thoracoscopy (n = 42), laparotomy (n = 5), combined laparoscopy and thoracoscopy (n = 8)] were analysed. Myotomy was performed in 437 patients (85.5%), and anti-reflux procedures were performed in 342 patients (69.5%). Overall pooled staple line leak rates were reported in 13.3% [95% c.i. (11.0-15.7), p < 0.001] and were less common after myotomy (12.4%) compared with no myotomy (26.1%, p = 0.002).
CONCLUSIONS
No consensus exists regarding the surgical treatment of non-Zenker's oesophageal diverticula, but staple line leakage is common and is reduced significantly by myotomy.

Review
BACKGROUND
Meckel Diverticulum [MD), a common congenital anomaly of the gastrointestinal tract, poses a dilemma when incidentally encountered during surgery. Despite historical descriptions and known complications of symptomatic MD, the decision to resect an incidental MD (IMD) lacks clear guidelines. This study aims to assess whether resecting IMDs is justified by synthesizing evidence from studies published between 2000 and 2023. Factors influencing this decision, such as demographic risks, surgical advancements and complications, are systematically examined.
METHODS AND MATERIAL
Following the PRISMA 2020 guidelines, this review incorporates 42 eligible studies with data on outcomes of asymptomatic MD management. Studies, both favoring and opposing resection, were analyzed.
RESULTS
Considering complications, malignancy potential, and operative safety, the risk-benefit analysis presents a nuanced picture. Some authors propose conditional resection based on specific criteria, emphasizing patient-specific factors. Of 2934 cases analyzed for short- and long-term complications, the morbidity rate was 5.69%. Of 571 cases where mortality data were available, all 5 fatalities were attributed to the primary disease rather than IMD resection.
CONCLUSION
The sporadic, unpredictable presentation of IMD and the variability of both the primary disease and the patient make formulation of definitive guidelines challenging. The non-uniformity of complications reporting underscores the need for standardized categorization. While the balance of evidence leans towards resection of IMDs, this study acknowledges the individualized nature of this decision. Increased safety in surgery and anesthesia, along with better understanding and management of complications favor a judicious preference for resection, while taking into account patient characteristics and the primary disease.

Review
Meckel's diverticulum is the most common congenital malformation of gastrointestinal tract. It can cause complications in the form of ulceration, haemorrhage, intussusception, intestinal obstruction, perforation and, very rarely, vesicodiverticular fistulae and tumours. These complications, especially bleeding, are more common in the paediatric age group than in adults; however it is not uncommon to miss the diagnosis of Meckel's diverticulum in adults. Here, we reviewed the literature regarding the complications of this forgotten clinical entity in adults with potential diagnostic difficulties and management strategies.

Meta-Analysis
Peroral endoscopic myotomy (POEM) is a rapidly evolving technique for the treatment of esophageal diverticulum. The aim of this study was to perform a systematic review and meta-analysis of the literature focusing on POEM for symptomatic esophageal diverticula, including an in-depth evaluation of its efficacy, safety, and limitations. A comprehensive literature search was completed to identify articles that examined the efficacy and safety of POEM for esophageal diverticula. Heterogeneity among studies was assessed using the I2 statistic. Meta-regression and sensitivity analyses were performed to explore the sources of heterogeneity and assess potentially important covariates influencing the main outcomes. Primary endpoints such as rates of success, adverse events, and recurrences were evaluated. P values of ≤0.05 were considered statistically significant. Nine studies with a total of 153 patients were enrolled. Pooled technical success, clinical success, adverse events, and recurrence rates were 99% [95% confidence interval (CI), 97-100%; I2 = 0%), 94% (95% CI, 89-97%; I2 = 24%), 2% (95% CI, 0-6%, I2 = 0%), and 0% (95% CI, 0-1%; I2 = 0%), respectively. The pooled perforation rate was 6% (95% CI, 1-11%; I2 = 0%). Meta-regression analysis indicated that esophageal diverticula types and motility disorders were not associated with the clinical success rate (P > 0.05). POEM is a feasible, safe, and effective treatment for symptomatic esophageal diverticula, with low adverse events and recurrence rates.

Review
INTRODUCTION
Diverticula (mucosal outpouching through the wall of the colon) are rare before the age of 40 years, after which prevalence increases steadily and reaches over 25% by 60 years. However, only 10% to 25% of affected people will develop symptoms such as lower abdominal pain. Recurrent symptoms are common, and 5% of people with diverticula eventually develop complications such as perforation, obstruction, haemorrhage, fistulae, or abscesses.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of: treatments for uncomplicated diverticular disease; treatments to prevent complications; and treatments for acute diverticulitis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 16 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: antispasmodics, elective surgery, increasing fibre intake with bran or ispaghula husk, lactulose, medical treatment, mesalazine, methylcellulose, rifaximin, and surgery.
