Outpatient Surgery and Unplanned Overnight Admission in Bilateral Inguinal Hernia Repair: A Population-based Study.

PURPOSE: The use of outpatient surgery in inguinal hernia is heterogeneous despite clinical recommendations. This study aimed to analyze the utilization trend of outpatient surgery for bilateral inguinal hernia repair (BHIR) in Spain and identify the factors associated with outpatient surgery choice and unplanned overnight admission. METHODS: A retrospective observational study of patients undergoing BIHR from 2016 to 2021 was conducted. The clinical-administrative database of the Spanish Ministry of Health RAE-CMBD was used. Patient characteristics undergoing outpatient and inpatient surgery were compared. A multivariable logistic regression analysis was performed to identify factors associated with outpatient surgery choice and unplanned overnight admission. RESULTS: A total of 30,940 RHIBs were performed; 63% were inpatient surgery, and 37% were outpatient surgery. The rate of outpatient surgery increased from 30% in 2016 to 41% in 2021 (p < 0.001). Higher rates of outpatient surgery were observed across hospitals with a higher number of cases per year (p < 0.001). Factors associated with outpatient surgery choice were: age under 65 years (OR: 2.01, 95% CI: 1.92-2.11), hospital volume (OR: 1.59, 95% CI: 1.47-1.72), primary hernia (OR: 1.89, 95% CI: 1.71-2.08), and laparoscopic surgery (OR: 1.47, 95% CI: 1.39-1.56). Comorbidities were negatively associated with outpatient surgery. Open surgery was associated (OR: 1.26, 95% CI: 1.09-1.47) with unplanned overnight admission. CONCLUSIONS: Outpatient surgery for BHIR has increased in recent years but is still low. Older age and comorbidities were associated with lower rates of outpatient surgery. However, the laparoscopic repair was associated with increased outpatient surgery and lower unplanned overnight admission.

Bilateral inguinal hernia repair by laparoscopic totally extraperitoneal (TEP) vs. laparoscopic transabdominal preperitoneal (TAPP).

BACKGROUND: The guidelines recommend laparoscopic repair for bilateral inguinal hernia. However, few studies compare the totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) techniques in bilateral inguinal hernias. This study aimed to compare the outcomes of TEP and TAPP in bilateral inguinal hernia. METHODS: We conducted a retrospective cohort study of patients operated on for bilateral inguinal hernia by TEP and TAPP repair from 2016 to 2020. Intraoperative complications, operative time, acute postoperative pain, hospital stay, postoperative complications, chronic inguinal pain, and recurrence were compared. RESULTS: A total of 155 patients were included in the study. TEP was performed in 71 patients (46%) and TAPP in 84 patients (54%). The mean operative time was longer in the TAPP group than in the TEP group (107 min vs. 82 min, p < 0.001). The conversion rate to open surgery was higher in the TEP group than in the TAPP group (8.5% vs. 0%, p = 0.008). The mean hospital stay was longer in the TAPP group than in the TEP group (p < 0.001). We did not observe significant differences in the proportion of postoperative complications (p = 0.672), postoperative pain at 24 h (p = 0.851), chronic groin pain (p = 0.593), and recurrence (p = 0.471). We did not observe an association between the choice of surgical technique (TEP vs. TAPP) with conversion rate, operative time, hospital stay, postoperative complications, chronic inguinal pain, or hernia recurrence when performing a multivariable analysis adjusted for the male sex, age, BMI, ASA, recurrent hernia repair, surgeon, and hernia size > 3cm. CONCLUSIONS: Bilateral inguinal hernia repair by TEP and TAP presented similar outcomes in our study.

Endoscopic Vacuum Therapy for Upper Gastrointestinal Leaks and Perforations: Analysis From a Multicenter Spanish Registry.

INTRODUCTION: Endoscopic vacuum therapy (EVT) is a novel technique for closing upper gastrointestinal (UGI) defects. Available literature includes single-center retrospective cohort studies with small sample sizes. Furthermore, evidence about factors associated with EVT failure is scarce. We aimed to assess the efficacy and safety of EVT for the resolution of UGI defects in a multicenter study and to investigate the factors associated with EVT failure and in-hospital mortality. METHODS: This is a prospective cohort study in which consecutive EVT procedures for the treatment of UGI defects from 19 Spanish hospitals were recorded in the national registry between November 2018 and March 2022. RESULTS: We included 102 patients: 89 with anastomotic leaks and 13 with perforations. Closure of the defect was achieved in 84 cases (82%). A total of 6 patients (5.9%) had adverse events related to the EVT. The in-hospital mortality rate was 12.7%. A total of 6 patients (5.9%) died because of EVT failure and 1 case (0.9%) due to a fatal adverse event. Time from diagnosis of the defect to initiation of EVT was the only independent predictor for EVT failure (odds ratio [OR] 1.03, 95% confidence interval [CI] 1.01-1.05, P = 0.005). EVT failure (OR 24.5, 95% CI 4.5-133, P = 0.001) and development of pneumonia after EVT (OR 246.97, 95% CI 11.15-5,472.58, P = 0.0001) were independent predictors of in-hospital mortality. DISCUSSION: EVT is safe and effective in cases of anastomotic leak and perforations of the upper digestive tract. The early use of EVT improves the efficacy of this technique.

Trends and predictors of laparoscopic bilateral inguinal hernia repair in Spain: a population-based study.

BACKGROUND: International guidelines currently recommend laparoscopy for bilateral inguinal hernia repair (BIHR). Our study aims to evaluate the trends and factors associated with the choice of laparoscopy for BIHR in Spain. METHODS: We performed a retrospective analysis of patients undergoing BIHR between 2016 and 2019. We used the national database of the Spanish Ministry of Health: RAE-CMBD. We performed a univariate and multivariable logistic regression analysis to identify the factors associated with the utilization of laparoscopy. We identified perioperative complications and the factors associated with their occurrence through multivariable logistic regression analysis. RESULTS: A total of 21,795 BIHRs were performed: 84% by open approach and 16% by laparoscopic approach. Laparoscopic approach increased from 12% in 2016 to 23% in 2019 (p < 0.001). The 40% of hospitals did not use laparoscopy, and only 8% of the hospitals performed more than 50% of their BIHRs by laparoscopy. The utilization rate of laparoscopy was not related to the number of BIHRs performed per year (p = 0.145). The main factor associated with the choice of laparoscopy in multivariable logistic regression analysis was the patient's region of residence (OR 2.04, 95% CI 1.88-2.21). Other factors were age < 65 years (OR 1.65, 95% CI 1.52-1.79) and recurrent inguinal hernia (OR 1.31, 95% CI 1.15-1.49). The type of approach for BIHR was not independently associated with perioperative complications. CONCLUSIONS: Despite a significant increase in recent years, laparoscopic BIHR in Spain remains low. The main factor associated with the utilization of laparoscopy was the patient's region of residence; this factor seems to be related to the presence of hospitals with a high rate of laparoscopic approaches where the patient lives. The type of approach was not independently associated with perioperative complications. More efforts are needed to increase laparoscopic use in patients with bilateral inguinal hernias.

Textbook outcome and survival after gastric cancer resection with curative intent: A population-based analysis.

BACKGROUND: The concept of textbook outcome (TO) has been proposed for analyzing quality of surgical care. This study assessed the incidence of TO among patients undergoing curative gastric cancer resection, predictors for TO achievement, and the association of TO with survival. METHOD: All patients with gastric and gastroesophageal junction cancers undergoing curative gastrectomy between January 2014-December 2017 were identified from a population-based database (Spanish EURECCA Registry). TO included: macroscopically complete resection at the time of operation, R0 resection, ≥15 lymph nodes removed and examined, no serious postoperative complications (Clavien-Dindo ≥II), no re-intervention, hospital stay ≤14 days, no 30-day readmissions and no 90-day mortality. Logistic regression was used to assess the adjusted achievement of TO. Cox survival regression was used to compare conditional adjusted survival across groups. RESULTS: In total, 1293 patients were included, and TO was achieved in 541 patients (41.1%). Among the criteria, "macroscopically complete resection" had the highest compliance (96.5%) while "no serious complications" had the lowest compliance (63.7%). Age (OR 0.53 for the 65-74 years and OR 0.34 for the ≥75 years age group), Charlson comorbidity index ≥3 (OR 0.53, 95%CI 0.34-0.82), neoadjuvant chemoradiotherapy (OR 0.24, 95%CI 0.08-0.70), multivisceral resection (OR 0.55, 95%CI 0.33-0.91), and surgery performed in a community hospital (OR 0.65, CI95% 0.46-0.91) were independently associated with not achieving TO. TO was independently associated with conditional survival (HR 0.67, 95%CI 0.55-0.83). CONCLUSION: TO was achieved in 41.1% of patients who underwent gastric cancer resection with curative intent and was associated with longer survival.

Budget Impact Analysis of Molecular Lymph Node Staging Versus Conventional Histopathology Staging in Colorectal Carcinoma.

BACKGROUND: The presence of lymph node (LN) metastasis is a critical prognostic factor in colorectal cancer (CRC) patients and is also an indicator for adjuvant chemotherapy. The gold standard (GS) technique for LN diagnosis and staging is based on the analysis of haematoxylin and eosin (H&E)-stained slides, but its sensitivity is low. As a result, patients may not be properly diagnosed and some may have local recurrence or distant metastases after curative-intent surgery. Many of these diagnostic and treatment problems could be avoided if the one-step nucleic acid amplification assay (OSNA) was used rather than the GS technique. OSNA is a fast, automated, standardised, highly sensitive, quantitative technique for detecting LN metastases. OBJECTIVES: The aim of this study was to assess the budget impact of introducing OSNA LN analysis in early-stage CRC patients in the Spanish National Health System (NHS). METHODS: A budget impact analysis comparing two scenarios (GS vs. OSNA) was developed within the Spanish NHS framework over a 3-year time frame (2017-2019). The patient population consisted of newly diagnosed CRC patients undergoing surgical treatment, and the following costs were included: initial surgery, pathological diagnosis, staging, follow-up expenses, systemic treatment and surgery after recurrence. One- and two-way sensitivity analyses were performed. RESULTS: Using OSNA instead of the GS would have saved €1,509,182, €6,854,501 and €10,814,082 during the first, second and third years of the analysis, respectively, because patients incur additional costs in later years, leading to savings of more than €19 million for the NHS over the 3-year time horizon. CONCLUSIONS: Introducing OSNA in CRC LN analysis may represent not only an economic benefit for the NHS but also a clinical benefit for CRC patients since a more accurate staging could be performed, thus avoiding unnecessary treatments.

Perioperative transfusion management in gastric cancer surgery: Analysis of the Spanish subset of the EURECCA oesophago-gastric cancer registry. / Conducta transfusional perioperatoria en la cirugía del cáncer gástrico: análisis del registro del grupo español EURECCA de cáncer esófago-gástrico.

INTRODUCTION: This study evaluated allogenic packed red blood cell (aPRBC) transfusion rates in patients undergoing resection for gastric cancer and the implementation of blood-saving protocols (BSP). METHODS: Retrospective study of all gastric cancer patients operated on with curative intent in Catalonia and Navarra (2011-2013) and included in the Spanish subset of the EURECCA Oesophago-Gastric Cancer Registry. Hospitals with BSP were defined as those with a preoperative haemoglobin (Hb) optimisation circuit associated with restrictive transfusion strategies. Predictors of aPRBC transfusion were identified by multinomial logistic regression analysis. RESULTS: A total of 652 patients were included, 274 (42.0%) of which received aPRBC transfusion. Six of the 19 participating hospitals had BSP and treated 145 (22.2%) patients. Low Hb level at diagnosis (10 vs 12.4g/dL), ASA score III/IV, pT3-4, open surgery, associated visceral resection, and having being operated on in a hospital without BSP were predictors of aPRBC transfusion, while low Hb level, associated visceral resection, and non-BSP hospital remained predictors in the multivariate analysis. In case of comparable risk factors for aPRBC transfusion, there was a higher use of preoperative intravenous iron treatment (26.2% vs 13.2%) and a lower percentage of transfusions (31.7% vs 45%) in hospitals with BSP. CONCLUSIONS: The perioperative transfusion rate in gastric cancer was 42%. Hospitals with BSP showed a significant reduction of blood transfusions but treated only 22% of patients. Main predictors of aPRBC were low Hb level, associated visceral resection, and undergoing surgery at a hospital without BSP.

Personalised Prehabilitation in High-risk Patients Undergoing Elective Major Abdominal Surgery: A Randomized Blinded Controlled Trial.

OBJECTIVE: The aim of this study was to assess the impact of personalized prehabilitation on postoperative complications in high-risk patients undergoing elective major abdominal surgery. SUMMARY BACKGROUND DATA: Prehabilitation, including endurance exercise training and promotion of physical activity, in patients undergoing major abdominal surgery has been postulated as an effective preventive intervention to reduce postoperative complications. However, the existing studies provide controversial results and show a clear bias toward low-risk patients. METHODS: This was a randomized blinded controlled trial. Eligible candidates accepting to participate were blindly randomized (1:1 ratio) to control (standard care) or intervention (standard care + prehabilitation) groups. Inclusion criteria were: i) age >70 years; and/or, ii) American Society of Anesthesiologists score III/IV. Prehabilitation covered 3 actions: i) motivational interview; ii) high-intensity endurance training; and promotion of physical activity. The main study outcome was the proportion of patients suffering postoperative complications. Secondary outcomes included the endurance time (ET) during cycle-ergometer exercise. RESULTS: We randomized 71 patients to the control arm and 73 to intervention. After excluding 19 patients because of changes in the surgical plan, 63 controls and 62 intervention patients were included in the intention-to-treat analysis. The intervention group enhanced aerobic capacity [ΔET 135 (218) %; P < 0.001), reduced the number of patients with postoperative complications by 51% (relative risk 0.5; 95% confidence interval, 0.3-0.8; P = 0.001) and the rate of complications [1.4 (1.6) and 0.5 (1.0) (P =  0.001)] as compared with controls. CONCLUSION: Prehabilitation enhanced postoperative clinical outcomes in high-risk candidates for elective major abdominal surgery, which can be explained by the increased aerobic capacity.

Giant Gastric Gastrointestinal Stromal Tumor (GIST).

Gastrointestinal stromal tumors (GIST) represent 0.1-3 % of gastrointestinal malignancy. Surgery is the mainstay of treatment, but in high-risk tumors, imatinib can help to achieve better oncological outcomes. We present a rare case of a patient with gastric GIST with very aggressive evolution in a short period of time despite the use of neoadjuvant therapy with imatinib.

Endoscopic tattooing of early colon carcinoma enhances detection of lymph nodes most prone to harbor tumor burden.

BACKGROUND: Colorectal cancer (CRC) screening programs result in the detection of early-stage asymptomatic carcinomas suitable to be surgically cured. Lymph nodes (LN) from early CRC are usually small and may be difficult to collect. Still, at least 12 LNs should be analyzed from colectomies, to ensure a reliable pN0 stage. Presurgical endoscopic tattooing improves LN procurement. In addition, molecular detection of occult LN tumor burden in histologically pN0 CRC patients is associated with a decreased survival rate. We aimed to study the impact of presurgical endoscopic tattooing on the molecular detection of LN tumor burden in early colon neoplasms. METHODS: A prospective cohort study from a CRC screening-based population was performed at a tertiary academic hospital. LNs from colectomies with and without preoperative endoscopic tattooing were assessed by two methods, hematoxylin and eosin (HE), and RT-LAMP, to detect tumor cytokeratin 19 (CK19) mRNA. We compared the amount of tumor burden and LN yields from tattooed and non-tattooed specimens. RESULTS: HE and RT-LAMP analyses of 936 LNs were performed from 71 colectomies containing early carcinomas and endoscopically unresectable adenomas (8 pT0, 17 pTis, 27 pT1, 19 pT2); 47 out of 71 (66.2 %) were tattooed. Molecular positivity correlated with the presence of tattoo in LN [p < 0.001; OR 3.1 (95 % CI 1.7-5.5)]. A significantly higher number of LNs were obtained in tattooed specimens (median 17 LN vs. 14.5 LN; p = 0.019). CONCLUSIONS: Endoscopic tattooing enables the analysis of those LNs most prone to harbor tumor cells and improves the number of LN harvested.

Endoscopic-assisted laparoscopic resection for gastric subepithelial tumors.

BACKGROUND: Laparoscopic resection is considered the treatment of choice for gastric subepithelial tumors. Occasionally, it is necessary to perform an intraoperative gastroscopy to localize the lesion. There are no data in the literature addressing the factors that can predict when a combined laparoscopic-endoscopic approach will be needed. METHODS: A retrospective cohort study using a prospectively collected database was conducted. From January 2005 to December 2013, all the patients undergoing a laparoscopic gastric resection for subepithelial tumors irresectable by endoscopy were reviewed. Potential predictive factors for the need of an intraoperative endoscopy were analyzed. RESULTS: Thirty-eight consecutive patients (22 men and 16 women) with a mean age of 67 (41-86) years underwent laparoscopic gastric resection for subepithelial tumors. Fourteen (36.8%) patients required intraoperative endoscopic assessment. The only significant factors related to the need of endoscopic assessment during surgery were tumor growth pattern (P = 0.002) and size (P = 0.001). CONCLUSIONS: An accurate description of tumor growth pattern and size by EUS is recommended in the preoperative assessment of gastric subepithelial tumors. Small tumors (≤18 mm) with an intraluminal growth may need a combined endoscopic-assisted laparoscopic management.

Transanal total mesorectal excision in rectal cancer: short-term outcomes in comparison with laparoscopic surgery.

OBJECTIVE: The aim of this study was to compare short-term results obtained with transanal total mesorectal excision (TME) and laparoscopic surgery. BACKGROUND: Transanal TME appears as an alternative in the treatment of rectal cancer and other rectal disease. Natural orifices transluminal endoscopic surgery using the rectum as access in colorectal surgery is intuitively better suited than other access routes. METHODS: All consecutive patients with middle or low rectal cancer submitted to surgery were included into a prospective cohort and treated by transanal TME assisted by laparoscopy. They were compared with a retrospective cohort of consecutive patients of identical characteristics treated by laparoscopic TME in the immediate chronological period. RESULTS: Thirty-seven patients were included in both study groups. No differences were observed between them with respect to baseline characteristics, thus emphasizing the comparability of both cohorts. Surgical time was higher in the laparoscopy group (252 ± 50 minutes) than in the transanal group (215 ± 60 minutes) (P < 0.01). Moreover, coloanal anastomosis was performed less frequently (16% vs 43%, respectively; P = 0.01) and distal margin was lower (1.8 ± 1.2 mm vs 2.7 ± 1.7 mm, respectively; P = 0.05) in the laparoscopy group than in the transanal one. Although there was no significant difference in 30-day postoperative complication rate (laparoscopy, 51% vs transanal, 32%; P = 0.16), early readmissions were more frequent in the laparoscopy group than in the transanal one (22% vs 6%, respectively; P = 0.03). CONCLUSIONS: Evaluation of short-term outcomes demonstrated that transanal TME is a feasible and safe technique associated with a shorter surgical time and a lower early readmission rate.
