Diverticular disease (DD) refers to the presence of diverticula throughout the gastrointestinal (GI) tract, mainly along colon. DDmight evolve into diverticulitis that is accompanied by severe clinical presentation, which includes abscess formation, perforation, stricture, obstructionand/or fistula.

The aim of the present review is to summarize the role of molecular and genetic factors in DD development, as well as their possible contributiontowards new prognostic indicators, diagnostic algorithms and new therapeutic approaches.

Except from common predisposing parameters, several genetic mutations, immune factors, neurotransmitters, hormones and proteindysfunctions have been associated to the early onset of DD symptoms, pathogenesis and prognosis of the disease. Specific structural changes in the colonicwall, altered matrix composition and compromised motility have been verified as possible pathogenic factors for the development of DD. Dysregulation inperistaltic activity and reduced ability of the longitudinal muscle to relax following contraction has been also associated with DD evolution. In addition, ithas been suspected that genetic defects combined with alterations in intestinal microbiota might play an important role in diverticulitis presentation.

We hypothesized that the COVID-19 pandemic may have modified dispensing of colonoscopy preparations, a proxy for the number of colonoscopies performed. We therefore studied changes in dispensing of colonoscopy preparations during the pandemic in France.

Using the French national health data system, we identified colonoscopy preparations dispensed from 2018 to 2020. The expected 2020 dispensations were estimated from 2018 to 2019 dispensations.

Dispensing of colonoscopy preparations decreased markedly during the eight weeks of national lockdown 83,045 colonoscopy preparations were dispensed, i.e., 181,826 (68.6%) fewer than expected. After lockdown, dispensing of colonoscopy preparations gradually returned to expected numbers. Overall, this represents an estimated decrease of roughly 250,000 colonoscopy preparations during the six-month period following onset of the pandemic. This shortfall in the dispensing of colonoscopy preparations was of the same order of magnitude in people under or over 50 years of age, in men and women, and in those in the highest and the lowest quintiles of the deprivation index.

In conclusion, roughly 250,000 fewer colonoscopy preparations were dispensed during the first six months of the COVID-19 pandemic in France. Deleterious consequences on morbidity and mortality related to gastroenterological diseases, such as colorectal cancer, are to be feared.

Extralevator abdominoperineal excision (ELAPE) for rectal cancer leaves a greater perineal defect which might result in significant perineal morbidity, and how to effectively close perineal defects remains a challenge for surgeons. This study aimed to comparatively evaluate the perineal-related complications of biologic mesh reconstruction and primary closure following ELAPE.

The electronic databases PubMed, EMBASE, Cochrane Library, and Web of Science were searched to screen out all eligible studies, which compared biologic mesh reconstruction with primary closure for perineal-related complications following ELAPE. Pooled data of perineal-related complications including overall wound complications, hernia, infection, dehiscence, chronic sinus, and chronic pain (12 months after surgery) were analyzed.

A total of four studies (one randomized controlled trial and three cohort studies) involving 544 patients (346 biologic mesh vs 198 primary closure) were included. With a median follow-up of 18.5 months (range, 2-71.5 months). Analysis of the pooled data indicated that the perineal hernia rate was significantly lower in biologic mesh reconstruction as compared to primary closure (OR, 0.38; 95% CI, 0.22-0.69; P = 0.001). There were no statistically significant differences between the two groups in terms of total perineal wound complications rate (P = 0.70), as well as rates of perineal wound infection (P = 0.97), wound dehiscence (P = 0.43), chronic sinus (P = 0.28), and chronic pain (12 months after surgery; P = 0.75).

Biologic mesh reconstruction after extralevator abdominoperineal excision appears to have a lower hernia rate, with no differences in perineal wound complications.

Neoadjuvant radiotherapy is commonly used in rectal cancer. When used prior to radical surgery in locally advanced disease, up to one-quarter of patients have no residual cancer at surgery suggesting that radical surgery was unnecessary; those with complete clinical response may be managed on a rectal-preserving 'watch-and-wait' pathway. In those receiving radiotherapy for early stage cancer, local excision of small volume residual or recurrent tumour is possible, but its value is unclear.

Data were collected from two institutions (UK and Denmark) which maintain prospective databases on all patients undergoing local excision by transanal endoscopic microsurgery (TEM). link2 The study group was all patients who had TEM after neoadjuvant radiation for rectal cancer over an 11-year period.

Forty-five patients had TEM after neoadjuvant radiation, 18 after short course radiotherapy (SCRT) and 27 after chemoradiotherapy (CRT). Local recurrence occurred in 13 (29%) and distant metastases in 11 (24%). Complete pathological response was noted in 10 (22%), 28% after SCRT and 19% after CRT, p = 0.02. However, local recurrence still occurred in 60% of those with ypT0 after SCRT. The recurrence rate may be higher in those with residual disease at TEM compared with complete responders (40 vs 30%).

If complete response can be determined clinically, local excision of the scar does not confer benefit, but follow-up should be maintained. If there is regrowth or residual tumour at TEM, further recurrence is common, and the benefits of TEM may not outweigh the risks, except in those unsuitable for radical surgery.

To assess whether intraperitoneal contamination index (ICI) (Hajibandeh index) derived from combined levels of CRP, lactate, neutrophils, lymphocytes, and albumin can predict the nature of intraperitoneal contamination in patients with acute abdominal pathology and to assess whether ICI can predict postoperative mortality in patients undergoing emergency laparotomy.

In order to prospectively validate the ICI, developed and validated retrospectively in our previous study, a multicentre prospective cohort study was conducted between January 2019 and June 2020 including all adult patients who presented with acute abdominal pathology requiring emergency laparotomy. ROC curve analysis was performed to determine discrimination and cut-off values of preoperative ICI that could predict the nature of intraperitoneal contamination and postoperative mortality.

Overall, 269 patients were included in the prospective validation cohort which were compared with 234 patients in the primary cohort and 234 patients in theence of purulent and feculent intraperitoneal contamination in patients with acute abdominal pathology and postoperative mortality in patients undergoing emergency laparotomy. Future studies should investigate the effect of ICI use on the accuracy of preoperative prognostic scoring tools and on patient selection for operative or non-operative management of underlying abdominal pathology.

Post-operative swelling and oedema following total knee arthroplasty (TKA) are one of the most important causes of dissatisfaction. We aimed to assess the clinical variables associated with post-operative swelling and edema after TKA and to compare their performance in respect of predicting them pre-operatively.

The study cohort comprised 116 patients who underwent TKA between January 2018 and May 2019 in our centre. The diameters and the grade of venous insufficiency (VI) in the lower extremity veins were measured with duplex ultrasonography preoperatively and at one and three months post-operatively. link3 The study cohort was divided into the patients with leg swelling positive with a difference in leg circumference of > 2cm (n = 56, 48.2%) and leg swelling negative with a difference of ≤ 2cm (n = 60, 51.7%) fromthe pre-operative leg diameter.

Independent predictors for lower extremity swelling were pre-operative great saphenous diameter (GSV) diameter > 5.5mm [odds ratio (OR) 2.51, 95% CI 0.24-0.91; p = 0.0012], GSV reflux > 1s [OR 3.28, 95% CI 1.16-12.1; p = 0.003], deep only VI [OR 1.32, 95% CI 0.74-1.87; p = 0.021], CEAP C4-6 [OR 1.62, 95% CI 0.36-0.91; p = 0.018], and hypothyroidism [OR 1.55, 95% CI 1.31-11.2; p = 0.031].

GSV diameter of > 5.38mm and GSV reflux duration > 1.23s had the best predictive value for lower extremity oedema following TKA.

 1.23 s had the best predictive value for lower extremity oedema following TKA.

Arthroscopic reconstruction of anterior cruciate ligament (ACL) surgical procedure using hamstring autograft is themost common surgery performed in the arena of sports medicine and arthroscopy. Most studies in literature are ambiguous regarding the fate of hamstrings based on function, regenerative potential, and cross-sectional area (CSA). The aim of this research study is analysis of the fate of hamstring tendons (both semitendinosus and gracilis) during the time course for determinants of regeneration and strength.

Fifty patients who were operated for unilateral isolated ACL reconstruction from July 2015 to June 2018 were evaluated for the fate of harvested hamstring tendons which included the following regeneration, cross-sectional area (CSA), strength, and insertion of regenerated hamstrings by isometric torque and isokinetic strength. MRI of knee was performed for both knees concerning the semitendinosus (ST), gracilis (G), Sartorius, biceps femoris, and medial head of gastrocnemius.

Eighty-four percent men and 16% women within a mean patient age of 34 ± 4.
