Influence of sarcopenia and frailty in the management of elderly patients with acute appendicitis

In developed countries,the average life expectancy has been increasing and is now well over 80 years.Increased life expectancy is associated with an increased number of emergency surgical procedures performed in later age groups.Acute appendicitis is one of the most common surgical diseases,with a lifetime risk of 8%.A growing incidence of acute appendicitis has been registered in the elderly population and in the oldest groups(>80 years).Among patients>50-year-old who present to the emergency department for acute abdominal pain,15%have acute appendicitis.In these patients,emergency surgery for acute appendicitis is challenging,and some important aspects must be considered.In the elderly,surgical treatment outcomes are influenced by sarcopenia.Sarcopenia must be considered a precursor of frailty,a risk factor for physical function decline.Sarcopenia has a negative impact on both elective and emergency surgery regarding mortality and morbidity.Aside from morbidity and mortality,the most crucial outcomes for older patients requiring emergency surgery are reduction in function decline and preoperative physical function maintenance.Therefore,prediction of function decline is critical.In emergency surgery,preoperative interventions are difficult to implement because of the narrow time window before surgery.In this editorial,we highlight the unique aspects of acute appendicitis in elderly patients and the influence of sarcopenia and frailty on the results of surgical treatment.

Indocyanine green:The guide to safer and more effective surgery

In this editorial we comment on the article by Kalayarasan and co-workers published in the recent issue of the World Journal of Gastrointestinal Surgery.The authors present an interesting review on the use of indocyanine green fluo-rescence in different aspects of abdominal surgery.They also highlight future perspectives of the use of indocyanine green in mini-invasive surgery.Indo-cyanine green,used for fluorescence imaging,has been approved by the Food and Drug Administration and is safe for use in humans.It can be administered in-travenously or intra-arterially.Since its advent,there have been several advance-ments in the applications of indocyanine green,especially in the surgical field,such as intraoperative mapping and biopsy of sentinel lymph node,measurement of hepatic function prior to resection,in neurosurgical cases to detect vascular anomalies,in cardiovascular cases for patency and assessment of vascular ab-normalities,in predicting healing following amputations,in helping visualization of hepatobiliary anatomy and blood vessels,in reconstructive surgery,to assess flap viability and for the evaluation of tissue perfusion following major trauma and burns.For these reasons,the intraoperative use of indocyanine green has become common in a variety of surgical specialties and transplant surgery.Co-lorectal surgery has just lately begun to adopt this technique,particularly for perfusion visualization to prevent anastomotic leakage.The regular use of in-docyanine green coupled with fluorescence angiography has recently been pro-posed as a feasible tool to help improve patient outcomes.Using the best available data,it has been shown that routine use of indocyanine green in colorectal surgery reduces the rates of anastomotic leak.The use of indocyanine green is proven to be safe,feasible,and effective in both elective and emergency scenarios.However,additional robust evidence from larger-scale,high-quality studies is essential before incorporating indocyanine green guided surgery into standard practice.

Has the open surgical approach in colorectal cancer really become uncommon?

Colorectal cancer is the third most common cancer in the world.Surgery is man-datory to treat patients with colorectal cancer.Can colorectal cancer be treated in laparoscopy?Scientific literature has validated the oncological quality of laparo-scopic approach for the treatment of patients with colorectal cancer.Randomized non-inferiority trials with good remote control have answered positively to this long-debated question.Early as 1994,first publications demonstrated technical feasibility and compliance with oncological imperatives and,as far as short-term outcomes are concerned,there is no difference in terms of mortality and post-operative morbidity between open and minimally invasive surgical approaches,but only longer operating times at the beginning of the experience.Subsequently,from 2007 onwards,long-term results were published that demonstrated the ab-sence of a significant difference regarding overall survival,disease-free survival,quality of life,local and distant recurrence rates between open and minimally in-vasive surgery.In this editorial,we aim to summarize the clinical and technical aspects which,even today,make the use of open surgery relevant and necessary in the treatment of patients with colorectal cancer.

Colonic Crohn’s disease-decision is more important than incision:A surgical dilemma

The most common localization for intestinal Crohn’s disease(CD)is the terminal ileum and ileocecal area.It is estimated that patients with CD have one in four chance of undergoing surgery during their life.As surgery in ulcerative colitis ultimately cures the disease,in CD,regardless of the extent of bowel removed,the risk of disease recurrence is as high as 40%.In elective surgery,management of isolated Crohn’s colitis continues to evolve.Depending on the type of surgery performed,colonic CD patients often require further medical or surgical therapy to prevent or treat recurrence.The elective surgical treatment of colonic CD is strictly dependent on the localization of disease,and the choice of the procedure is dependent of the extent of colonic involvement and previous resection.The most common surgical options in colonic CD are total proctocolectomy(TPC)with permanent ileostomy,segmental bowel resection,subtotal colectomy.TPC completely removes all colonic and rectal disease and avoids the use of a potentially diseased anus.We will review current options for the elective surgical treatment of colonic CD,based on the current literature and our own personal experience.

Anastomotic leakage in rectal cancer surgery:Retrospective analysis of risk factors

BACKGROUND Anastomotic leakage(AL)after restorative surgery for rectal cancer(RC)is associated with significant morbidity and mortality.AIM To ascertain the risk factors by examining cases of AL in rectal surgery in this retrospective cohort study.METHODS To identify risk factors for AL,a review of 583 patients who underwent rectal resection with a double-stapling colorectal anastomosis between January 2007 and January 2022 was performed.Clinical,demographic and operative features,intraoperative outcomes and oncological characteristics were evaluated.RESULTS The incidence of AL was 10.4%,with a mean time interval of 6.2±2.1 d.Overall mortality was 0.8%.Mortality was higher in patients with AL(4.9%)than in patients without leak(0.4%,P=0.009).Poor bowel preparation,blood transfusion,median age,prognostic nutritional index<40 points,tumor diameter and intraoperative blood loss were identified as risk factors for AL.Location of anastomosis,number of stapler cartridges used to divide the rectum,diameter of circular stapler,level of vascular section,T and N status and stage of disease were also correlated to AL in our patients.The diverting ileostomy did not reduce the leak rate,while the use of the transanastomic tube significantly did.CONCLUSION Clinical,surgical and pathological factors are associated with an increased risk of AL.It adversely affects the morbidity and mortality of RC patients.
