BACKGROUND
Incisional hernia is a frequent complication of abdominal wall incision. Surgical technique is an important risk factor for the development of incisional hernia. The aim of these updated guidelines was to provide recommendations to decrease the incidence of incisional hernia.
METHODS
A systematic literature search of MEDLINE, Embase, and Cochrane CENTRAL was performed on 22 January 2022. The Scottish Intercollegiate Guidelines Network instrument was used to evaluate systematic reviews and meta-analyses, RCTs, and cohort studies. The GRADE approach (Grading of Recommendations, Assessment, Development and Evaluation) was used to appraise the certainty of the evidence. The guidelines group consisted of surgical specialists, a biomedical information specialist, certified guideline methodologist, and patient representative.
RESULTS
Thirty-nine papers were included covering seven key questions, and weak recommendations were made for all of these. Laparoscopic surgery and non-midline incisions are suggested to be preferred when safe and feasible. In laparoscopic surgery, suturing the fascial defect of trocar sites of 10 mm and larger is advised, especially after single-incision laparoscopic surgery and at the umbilicus. For closure of an elective midline laparotomy, a continuous small-bites suturing technique with a slowly absorbable suture is suggested. Prophylactic mesh augmentation after elective midline laparotomy can be considered to reduce the risk of incisional hernia; a permanent synthetic mesh in either the onlay or retromuscular position is advised.
CONCLUSION
These updated guidelines may help surgeons in selecting the optimal approach and location of abdominal wall incisions.

Meta-Analysis Review
BACKGROUND
Enterocutaneous fistula (ECF) is an abnormal communication between the gastrointestinal tract and skin, with a myriad of etiologies and therapeutic options. Management is influenced by etiology and specifics of the ECF, and patient-related factors. The aim of this study was to assess overall success, recurrence, and mortality rates of treatment for ECF.
MATERIALS
A systematic search of PubMed and Google Scholar was performed through October 2021 according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Case reports, reviews, animal studies, studies not reporting outcomes, had no available English text, included patients < 16 years old or those assessing other abdominocutaneous/internal fistulas were excluded.
RESULTS
Fifty-three studies, between 1975 and 2020, incorporating 3078 patients were included. Patient age ranged between 16 and 87 years with a male:female ratio of 1.14:1. ECF developed postoperatively in 89.4%. Other common etiologies were inflammatory bowel disease, trauma, malignancy, and radiation. At least 28% of patients had complex fistulae (reported in 18 studies). Most common fistula site was small bowel. In 34 publications, 62.4% (n = 1371) patients received parenteral nutrition. In 45 publications, 72.5% underwent surgery to treat the fistula. Meta-analysis revealed an 89% healing rate; recurrence rate after initial successful treatment was 11.1%, and mortality rate was 8.5%. In a subgroup of patients who underwent combined ECF takedown and abdominal wall reconstructions (n = 315), 78% achieved fascial closure, mesh was used in 72%, hernia, and fistula recurrence rates were 19.7% and 7.6%, respectively.
CONCLUSIONS
Treatment of ECF must be individualized according to specific etiology and location of the fistula and the patient's associated conditions.

Review
Anorectal emergencies comprise a wide variety of diseases that share common symptoms, i.e., anorectal pain or bleeding and might require immediate management. While most of the underlying conditions do not need inpatient management, some of them could be life-threatening and need prompt recognition and treatment. It is well known that an incorrect diagnosis is frequent for anorectal diseases and that a delayed diagnosis is related to an impaired outcome. This paper aims to improve the knowledge and the awareness on this specific topic and to provide a useful tool for every physician dealing with anorectal emergencies.The present guidelines have been developed according to the GRADE methodology. To create these guidelines, a panel of experts was designed and charged by the boards of the World Society of Emergency Surgery (WSES) and American Association for the Surgery of Trauma (AAST) to perform a systematic review of the available literature and to provide evidence-based statements with immediate practical application. All the statements were presented and discussed during the WSES-AAST-WJES Consensus Conference on Anorectal Emergencies, and for each statement, a consensus among the WSES-AAST panel of experts was reached. We structured our work into seven main topics to cover the entire management of patients with anorectal emergencies and to provide an up-to-date, easy-to-use tool that can help physicians and surgeons during the decision-making process.

Journal of Minimally Invasive Gynecology Feb 2020To conduct a systematic review of the literature on patients with extrapelvic deep endometriosis.
OBJECTIVE
To conduct a systematic review of the literature on patients with extrapelvic deep endometriosis.
DATA SOURCES
A thorough search of the PubMed/Medline, Embase, and Cochrane databases was performed.
METHODS OF STUDY SELECTION
Studies in the last 20 years that reported on primary extrapelvic endometriosis were included (PROSPERO registration number CRD42019125370).
TABULATION, INTEGRATION, AND RESULTS
The initial search identified 5465 articles, and 179 articles, mostly case reports and series, were included. A total of 230 parietal (PE), 43 visceral (VE), 628 thoracic (TE), 6 central nerve system, 12 extrapelvic muscle or nerve, and 1 nasal endometriosis articles were identified. Abdominal endometriosis was divided into PE and VE. PE lesions involved primary lesions of the abdominal wall, groin, and perineum. When present, symptoms included a palpable mass (99%), cyclic pain (71%) and cyclic bleeding (48%). Preoperative clinical suspicion was low, the use of tissue diagnosis was indeterminate (25%), and a few (8%) malignancies were suspected. Surgical treatment for PE included wide local excision (97%), with 5% recurrence and no complications. Patients with VE involving abdominal organs - kidneys, liver, pancreas, and biliary tract - were treated surgically (86%) with both conservative (51%) and radical resection (49%), with 15% recurrence and 2 major complications reported. In patients with TE involving the diaphragm, pleura, and lung, isolated and concomitant lesions occurred and favored the right side (80%). Patients with TE presented with the triad of catamenial pain, pneumothorax, and hemoptysis. Thoracoscopy with resection followed by pleurodesis was the most common procedure performed, with 29% recurrence. Adjuvant medical therapy with gonadotropin-releasing hormone was administered in 15% of cases. Preoperative magnetic resonance imaging was performed in all cases of nonthoracic and nonabdominal endometriosis. Common symptoms were paresthesia and cyclic pain with radiation. Surgical resection was reported in 84%, with improvement of symptoms.
CONCLUSION
Extrapelvic endometriosis, traditionally thought to be rare, has been reported in a considerable number of cases. Heightened awareness and clinical suspicion of the disease and a multidisciplinary approach are recommended to achieve a prompt diagnosis and optimize patient outcomes. Currently, there are no comparative studies to provide recommendations regarding optimal diagnostic methods, treatment options, and outcomes for endometriosis involving extrapelvic sites.

Meta-Analysis Review
PURPOSE
To systematically review technical aspects and treatment regimens of botulinum toxin A (BTA) injections in the lateral abdominal wall musculature. We also investigated the effect of BTA on abdominal muscle- and hernia dimensions, and clinical outcome.
METHODS
PubMed, EMBASE, CENTRAL, and CINAHL were searched for studies that investigate the injection of BTA in the lateral abdominal wall muscles. Study characteristics, BTA treatment regimens, surgical procedures, and clinical outcomes are presented descriptively. The effect of BTA on muscle- and hernia dimensions is analyzed using random-effects meta-analyses, and exclusively for studies that investigate ventral incisional hernia patients.
RESULTS
We identified 23 studies, comprising 995 patients. Generally, either 500 units of Dysport or 200-300 units of Botox are injected at 3-5 locations bilaterally in all three muscles of the lateral abdominal wall, about 4 weeks prior to surgery. No major procedural complications are reported. Meta-analyses show that BTA provides significant elongation of the lateral abdominal wall of 3.2 cm per side (95% CI 2.0-4.3, I = 0%, p < 0.001); 6.3 cm total elongation, and a significant but heterogeneous decrease in transverse hernia width (95% CI 0.2-6.8, I = 94%, p = 0.04). Furthermore, meta-analysis shows that BTA pretreatment in ventral hernia patients significantly increases the fascial closure rate [RR 1.08 (95% CI 1.02-1.16, I = 0%, p = 0.02)].
CONCLUSION
The injection technique and treatment regimens of botulinum toxin A as well as patient selection require standardization. Bilateral pretreatment in hernia patients significantly elongates the lateral abdominal wall muscles, making fascial closure during surgical hernia repair more likely.
STUDY REGISTRATION
A review protocol for this meta-analysis was registered at PROSPERO (CRD42020198246).

Review
BACKGROUND
Currently, there are five major approaches to hysterectomy for benign gynaecological disease: abdominal hysterectomy (AH), vaginal hysterectomy (VH), laparoscopic hysterectomy (LH), robotic-assisted hysterectomy (RH) and vaginal natural orifice hysterectomy (V-NOTES). Within the LH category we further differentiate the laparoscopic-assisted vaginal hysterectomy (LAVH) from the total laparoscopic hysterectomy (TLH) and single-port laparoscopic hysterectomy (SP-LH).
OBJECTIVES
To assess the effectiveness and safety of different surgical approaches to hysterectomy for women with benign gynaecological conditions.
SEARCH METHODS
We searched the following databases (from their inception to December 2022): the Cochrane Gynaecology and Fertility Specialised Register of Controlled Trials, CENTRAL, MEDLINE, Embase, CINAHL and PsycINFO. We also searched the trial registries and relevant reference lists, and communicated with experts in the field for any additional trials.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) in which clinical outcomes were compared between one surgical approach to hysterectomy and another.
DATA COLLECTION AND ANALYSIS
At least two review authors independently selected trials, assessed risk of bias and performed data extraction. Our primary outcomes were return to normal activities, satisfaction and quality of life, intraoperative visceral injury and major long-term complications (i.e. fistula, pelvic-abdominal pain, urinary dysfunction, bowel dysfunction, pelvic floor condition and sexual dysfunction).
MAIN RESULTS
We included 63 studies with 6811 women. The evidence for most comparisons was of low or moderate certainty. The main limitations were poor reporting and imprecision. Vaginal hysterectomy (VH) versus abdominal hysterectomy (AH) (12 RCTs, 1046 women) Return to normal activities was probably faster in the VH group (mean difference (MD) -10.91 days, 95% confidence interval (CI) -17.95 to -3.87; 4 RCTs, 274 women; I = 67%; moderate-certainty evidence). This suggests that if the return to normal activities after AH is assumed to be 42 days, then after VH it would be between 24 and 38 days. We are uncertain whether there is a difference between the groups for the other primary outcomes. Laparoscopic hysterectomy (LH) versus AH (28 RCTs, 3431 women) Return to normal activities may be sooner in the LH group (MD -13.01 days, 95% CI -16.47 to -9.56; 7 RCTs, 618 women; I = 68%, low-certainty evidence), but there may be more urinary tract injuries in the LH group (odds ratio (OR) 2.16, 95% CI 1.19 to 3.93; 18 RCTs, 2594 women; I = 0%; moderate-certainty evidence). This suggests that if the return to normal activities after abdominal hysterectomy is assumed to be 37 days, then after laparoscopic hysterectomy it would be between 22 and 25 days. It also suggests that if the rate of ureter injury during abdominal hysterectomy is assumed to be 0.2%, then during laparoscopic hysterectomy it would be between 0.2% and 2%. We are uncertain whether there is a difference between the groups for the other primary outcomes. LH versus VH (22 RCTs, 2135 women) We are uncertain whether there is a difference between the groups for any of our primary outcomes. Both short- and long-term complications were rare in both groups. Robotic-assisted hysterectomy (RH) versus LH (three RCTs, 296 women) None of the studies reported satisfaction rates or quality of life. We are uncertain whether there is a difference between the groups for our other primary outcomes. Single-port laparoscopic hysterectomy (SP-LH) versus LH (seven RCTs, 621 women) None of the studies reported satisfaction rates, quality of life or major long-term complications. We are uncertain whether there is a difference between the groups for rates of intraoperative visceral injury. Total laparoscopic hysterectomy (TLH) versus laparoscopic-assisted vaginal hysterectomy (LAVH) (three RCTs, 233 women) None of the studies reported satisfaction rates or quality of life. We are uncertain whether there is a difference between the groups for rates of intraoperative visceral injury or major long-term complications. Transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) versus LH (two RCTs, 96 women) We are uncertain whether there is a difference between the groups for rates of bladder injury. Our other primary outcomes were not reported. Overall, adverse events were rare in the included studies.
AUTHORS' CONCLUSIONS
Among women undergoing hysterectomy for benign disease, VH appears to be superior to AH. When technically feasible, VH should be performed in preference to AH because it is associated with faster return to normal activities, fewer wound/abdominal wall infections and shorter hospital stay. Where VH is not possible, LH has advantages over AH including faster return to normal activities, shorter hospital stay, and decreased risk of wound/abdominal wall infection, febrile episodes or unspecified infection, and transfusion. These advantages must be balanced against the increased risk of ureteric injury and longer operative time. When compared to LH, VH was associated with no difference in time to return to normal activities but shorter operative time and shorter hospital stay. RH and V-NOTES require further evaluation since there is a lack of evidence of any patient benefit over conventional LH. Overall, the evidence in this review has to be interpreted with caution as adverse event rates were low, resulting in low power for these comparisons. The surgical approach to hysterectomy should be discussed with the patient and decided in the light of the relative benefits and hazards. Surgical expertise is difficult to quantify and poorly reported in the available studies and this may influence outcomes in ways that cannot be accounted for in this review. In conclusion, when VH is not feasible, LH has multiple advantages over AH, but at the cost of more ureteric injuries. Evidence is limited for RH and V-NOTES.

BACKGROUND/OBJECTIVE
There is increasing use of computed tomography (CT) in sarcopenia research using a wide variety of techniques. We performed a systematic review of the CT literature to identify the differences between approaches used.
METHODS
A comprehensive search of PubMed from 1983 to 2017 was performed to identify studies that used CT muscle measurements to assess muscle mass and myosteatosis. The CT protocols were evaluated based on anatomic landmark(s), thresholding, muscle(s) segmented, key measurement (ie, muscle attenuation, cross-sectional area, volume), derived variables, and analysis software. From the described search, 657 articles were identified and 388 studies met inclusion criteria for this systematic review.
RESULTS
Muscle mass was more commonly assessed than myosteatosis (330 vs. 125). The most commonly assessed muscle or muscle groups were total abdominal wall musculature (142/330 and 49/125 for muscle mass and myosteatosis, respectively) and total thigh musculature (90/330 and 48/125). The most commonly used landmark in the abdomen was the L3 vertebra (123/142 and 45/49 for muscle mass and myosteatosis, respectively). Skeletal muscle index and intermuscular adipose tissue were the most commonly used measures of abdominal wall muscle mass (114/142) and myosteatosis (27/49), respectively. Cut points varied across studies. A significant majority of studies failed to report important CT technical parameters, such as use of intravenous contrast and slice thickness (94% and 63%, respectively).
CONCLUSIONS
There is considerable variation in the CT approaches used for the assessment of muscle mass and myosteatosis. There is a need to develop consensus for CT-based evaluation of sarcopenia and myosteatosis.

Meta-Analysis
BACKGROUND
Ventra hernias are increasing in prevalence and many recur despite attempted repair. To date, much of the literature is underpowered and divergent. As a result there is limited high quality evidence to inform surgeons succinctly which perioperative variables influence postoperative recurrence. This systematic review aimed to identify predictors of ventral hernia recurrence.
METHODS
PubMed was searched for studies reporting prognostic data of ventral hernia recurrence between 1 January 1995 and 1 January 2018. Extracted data described hernia type (primary/incisional), definitions of recurrence, methods used to detect recurrence, duration of follow-up, and co-morbidity. Data were extracted for all potential predictors, estimates and thresholds described. Random-effects meta-analysis was used. Bias was assessed with a modified PROBAST (Prediction model Risk Of Bias ASsessment Tool).
RESULTS
Screening of 18 214 abstracts yielded 274 individual studies for inclusion. Hernia recurrence was defined in 66 studies (24.1 per cent), using 41 different unstandardized definitions. Three patient variables (female sex, age 65 years or less, and BMI greater than 25, 30, 35 or 40 kg/m2), five patient co-morbidities (smoking, diabetes, chronic obstructive pulmonary disease, ASA grade III-IV, steroid use), two hernia-related variables (incisional/primary, recurrent/primary), six intraoperative variables (biological mesh, bridged repair, open versus laparoscopic surgery, suture versus mesh repair, onlay/retrorectus, intraperitoneal/retrorectus), and six postoperative variables (any complication, surgical-site occurrence, wound infection, seroma, haematoma, wound dehiscence) were identified as significant prognostic factors for hernia recurrence.
CONCLUSION
This study summarized the current evidence base for predicting ventral hernia recurrence. Results should inform best practice and future research.

Review
PURPOSE
Congenital lumbar hernia is defined as the protrusion of intraperitoneal or extraperitoneal viscera through a defect of the posterior abdominal wall, present at birth. The aim of our study was to perform a systematic review of this rare pathology, with emphasis on surgical decision-making.
METHODS
The English literature (2000-2020) was reviewed, using PubMed, EMBASE and GoogleScholar databases, combining the terms "hernia", "lumbar", "flank", "Grynfeltt", "Petit" and "congenital". Overall, 35 studies were included, describing 85 patients.
RESULTS
Mean age was 9.7 ± 20.7 months (range 1 day-10 years). 55.7% were males and 44.3% were females. All patients presented electively, with flank bulging as the main symptom. Superior lumbar triangle (Grynfeltt) herniae accounted for 41.8%, inferior lumbar triangle (Petit) herniae for 32.8%, whereas 25.4% were classified as diffuse. A left-sided hernia was observed in 47%, a right-sided in 42.4%, while 10.6% were bilateral. 71.8% of the patients had associated anatomical anomalies, mainly the lumbocostovertebral syndrome. Most patients (83.3%) were treated surgically, while 16.7% conservatively with surveillance. In 93.3%, the surgical approach was open, with laparoscopy employed in 6.7% of cases. The majority (71.7%) underwent primary suture repair of the hernia defect, whereas a mesh was required in 28.3%. Post-operative morbidity was 6.7% and recurrence rate was 3.3% at a mean follow-up of 26.4 months.
CONCLUSION
Congenital lumbar hernia is a rare pathology in the paediatric population, with only 85 cases reported since 2000. Although the diagnosis is frequently straightforward, it should raise the suspicion for associated congenital anomalies and further investigation is required, with cross-sectional imaging. Surgical repair is usually performed during the first year, to allow for symmetrical torso development.

Review
Knowledge of the changes that occur in the abdominal wall after component separation (CS) is essential for understanding the mechanisms of action of the various CS techniques, the changes observed on computed tomography images, and, perhaps most importantly, the anatomic and physiologic changes observed in patients who have undergone CS. Purpose Component separation (CS) techniques are essential adjuncts during most abdominal wall reconstructions. They allow the fulfillment of most modern abdominal wall reconstruction principles, especially primary closure of defects and linea alba restoration under physiologic tension. Knowledge of the post-CS abdominal wall changes is essential to understanding the mechanism of action of the various types of CS, the changes observed on computed tomographic images, and, perhaps most importantly, the anatomic and physiologic changes following CS techniques. Methods A systematic review of the literature was conducted using the PubMed database and other sources to identify articles describing abdominal wall changes after CS Results After excluding non-pertinent articles, 14 articles constituted the basis for this review. Conclusions After reviewing the literature on post CS abdominal wall changes, we conclude the following: (1)The external oblique muscle is significantly displaced laterally after anterior CS, the transversus abdominis muscle shifts very little after posterior CS, and muscle trophism is generally maintained after both techniques. These findings are consistent for both open and minimally invasive CS. (2) The anatomy and physiology of abdominal wall muscles are preserved mainly by the muscles' overlapping function and their ability to undergo compensatory trophism after midline restoration (reloading). (3) Well-performed CS techniques have a low risk of producing bulging and semilunar line hernias. (4) Anterior and posterior CS techniques probably have different mechanisms of action. (5) Current studies on how the nutritional status and postoperative conditioning can alter abdominal wall changes after CS and the mechanisms of the actions involved in anterior and posterior CS are underway.
