RESUMO
BACKGROUND: Retroperitoneal sarcomas (RPSs) present a surgical challenge, with complex anatomic relationships to organs and vascular structures. This pilot study investigated the role of three-dimensional (3D) augmented reality (3DAR) compared with standard imaging in preoperative planning and resection strategies. METHODS: For the study, 13 patients who underwent surgical resection of their RPS were selected based on the location of their tumor (right, left, pelvis). From the patients' preoperative computed tomography (CT) scans, 3DAR models were created using a D2P program and projected by an augmented-reality (AR) glass (Hololens). The 3DAR models were evaluated by three experienced sarcoma surgeons and compared with the baseline two-dimensional (2D) contrast-enhanced CT scans. RESULTS: Three members of the surgical team evaluated 13 models of retroperitoneal sarcomas, resulting in a total of 26 responses. When the surgical team was asked to evaluate whether the 3DAR better prepared the surgeon for planned surgical resection, 10 responses favored the 3DAR, 5 favored the 2D CT scans and 11 showed no difference (p = 0.074). According to 15 (57.6 %) of the 26 responses, the 3DAR offered additional value over standard imaging in the preoperative planning (median score of 4; range, 1-5). The median stated likelihood that the surgeons would consult the 3DAR was 5 (range, 2-5) for the preoperative setting and 3 (range, 1-5) for the intraoperative setting. CONCLUSIONS: This pilot study suggests that the use of 3DAR may provide additional value over current standard imaging in the preoperative planning for surgical resection of RPS, and the technology merits further study.
RESUMO
BACKGROUND: Crohn's disease is considered a contraindication for IPAA. In our prior study, when IPAA was used intentionally for well-defined Crohn's disease, we found a high incidence of recurrent disease with a low incidence of pouch failure. OBJECTIVE: This study aimed to replicate these findings in a larger cohort over a longer period. DESIGN: Retrospective review of a prospective IBD registry. SETTINGS: Large IBD referral center. PATIENTS: Patients with preoperative colorectal Crohn's disease requiring surgery were included in the study. INTERVENTION: IPAA. MAIN OUTCOME MEASURES: Long-term Crohn's disease recurrence, pouch failure, and pouch function. RESULTS: Forty-six patients were identified. Crohn's disease was diagnosed on the basis of perianal disease (n = 18; 39%), small-bowel disease (n = 16; 35%), noncaseating granuloma (n = 10; 22%), and discontinuous inflammation (colorectal skip lesions) (n = 11; 24%). After a median follow-up of 93 (7-291) months, 22 patients (48%) developed recurrent Crohn's disease based on afferent limb disease (n = 14; 30%) or pouch fistulizing disease (n = 8; 18%). Only 4 patients (9%) developed pouch failure. No clinical factor was associated with Crohn's disease recurrence. Young age at the time of surgery and short duration of disease before IPAA were associated with pouch fistula recurrence ( p = 0.003 and p = 0.03, respectively). Most patients (86%) reported excellent continence, with no urgency (67%) and median stool frequency of 6 (range, 3-9) per day. LIMITATION: Retrospective nature and relatively small sample size. CONCLUSION: This largest reported series examining the intentional use of IPAA in Crohn's disease showed a high (48%) incidence of postoperative Crohn's disease with a low (9%) incidence of pouch failure. Young age and short disease course before surgery were risk factors for poor outcomes. Highly motivated patients with colorectal Crohn's disease may consider IPAA and avoid a definitive ileostomy.

RESULTADOS A LARGO PLAZO Y FACTORES PREDICTORES DE RESULTADOS DE LA ANASTOMOSIS ILEOANAL CON RESERVORIO CUANDO SE USA INTENCIONALMENTE PARA LA ENFERMEDAD DE CROHN BIEN DEFINIDA: ANTECEDENTES: La enfermedad de Crohn (EC) se considera una contraindicación para la anastomosis ileoanal con reservorio (IPAA). Nuestro estudio previo de IPAA cuando fue usada intencionalmente para EC bien definida mostró una alta incidencia de enfermedad recurrente con una baja incidencia de falla del reservorio.OBJETIVO: Replicar estos hallazgos en una cohorte más grande durante un período más largo.DISEÑO: Revisión retrospectiva de una base de datos prospectiva de enfermedad inflamatoria intestinal.ESCENARIO: Un centro grande de referencia de EII.PACIENTES: EC colorrectal preoperatoria con necesidad de tratamiento quirúrgico.INTERVENCIÓN: Anastomosis ileoanal con reservorio.RESULTADOS PRINCIPALES: Recurrencia de EC a largo plazo, falla del reservorio y función del reservorio.RESULTADOS: Cuarenta y seis pacientes fueron identificados. El diagnóstico de EC se basó en enfermedad perianal (n = 18; 39%), enfermedad del intestino delgado (n = 16; 35%), granuloma no caseificante (n = 10; 22%) e inflamación discontinua (lesiones salteadas colorrectales) (n = 11; 24%). Después de una mediana de seguimiento de 93 (7-291) meses, 22 (48 %) pacientes desarrollaron EC recurrente debido a enfermedad del asa aferente (n = 14; 30%) o enfermedad fistulizante del reservorio (n = 8; 18%). Solo 4 (9%) pacientes desarrollaron falla del reservorio. Ningún factor clínico se asoció con la recurrencia de EC. La edad joven en el momento de la cirugía y la corta duración de la enfermedad antes de IPAA se asociaron con la recurrencia de la fístula del reservorio ( p = 0.003 y p = 0.03, respectivamente). El recuento de plaquetas preoperatorio más alto fue la única característica clínica significativamente asociada con el fracaso del reservorio ( p = 0.02). La mayoría de los pacientes (86%) reportaron una continencia excelente, sin urgencia (67%) y una mediana de frecuencia evacuatoria de 6 (rango, 3-9) por día.LIMITACIONES: Naturaleza retrospectiva y tamaño de muestra relativamente pequeño.CONCLUSIÓN: Esta serie, la más grande reportada que examina el uso intencional de IPAA en la EC mostró una incidencia alta (48Rectal Cancer: Clinical and Molecular Predictors of a Complete Response to Total Neoadjuvant Therapy%) de EC posoperatoria con una incidencia baja (9%) de falla del reservorio. La edad joven y el curso corto de la enfermedad antes de la cirugía fueron factores de riesgo para pobres resultados. Pacientes altamente motivados con EC colorrectal pueden considerar una IPAA y evitar una ileostomía permanente. Consulte Video Resumen en http://links.lww.com/DCR/C171 .

INTRODUCTION: Soft tissue sarcomas (STS) of the pelvis present a surgical and oncological challenge. We investigated the outcomes of patients undergoing resection of pelvic sarcomas. METHODS: A retrospective analysis of all patients who underwent surgical resection for STS between 2014 and 2021 at a tertiary academic referral center (n = 172). Included all patients with primary or recurrent STS which originated or extended to the pelvic cavity (n = 29). RESULTS: The cohort was divided into primary pelvic sarcomas (n = 18) and recurrent pelvic sarcomas (rPS, n = 11). Complete R0/R1 resection was achieved in 26 patients (89.6%). The postoperative complication rate was 48.3%. The rate of major complications was 27.5%. The median time of follow-up from surgery was 12.3 months (range, 0.6-60.3 months). Disease-free survival was superior in the primary pelvic sarcomas group compared to the rPS group (P = 0.002). However, there was no significant difference in overall survival, (P = 0.52). Univariant and multivariant analyses identified rPS group (Hazard Ratio 8.68, P = 0.006) and resection margins (Hazard Ratio 6.29, P = 0.004) to be independently associated with disease-free survival. CONCLUSIONS: We have demonstrated that achieving R0/R1 resection is feasible. Oncological outcomes are favorable for primary tumors, whereas recurrent tumors exhibit early recurrences. Consideration of resection of recurrent pelvic STS should involve a careful multidisciplinary evaluation.

PURPOSE: Assess the subjective impact of gastro-esophageal reflux disease (GERD) symptoms on patients undergoing revision from laparoscopic sleeve gastrectomy (LSG) to one-anastomosis gastric bypass (OAGB) using the Reflux Disease Questionnaire for GERD (RDQ) and the GERD-health related quality of life score (GERD-HRQL), prior to- and following conversion. METHODS: Patients undergoing revision from LSG to OAGB were prospectively followed between May 2015 and December 2020. Data retrieved included demographics, anthropometrics, previous bariatric history, time interval between LSG and OAGB, weight loss, and co-morbidities. Pre- and post-OAGB RDQ and GERD-HRQL questionnaires were obtained. In the case of sleeve dilatation, sleeve resizing was performed. RESULTS: During the study period, 37 patients underwent revision from LSG to OAGB. Mean ages at LSG and pre-OAGB were 38 ± 11.74 and 46 ± 12.75, respectively. Median follow-up time was 21.5 months (range 3-65). All patients underwent sleeve resizing. RDQ and GERD-HRQL scores were obtained at a median of 14 months (range 3-51) between pre- and post-OAGB. Median RDQ score pre-OAGB vs post-OAGB was significantly reduced (30 (range 12-72) vs 14 (range 12-60), p = 0.007). All 3 parts of the GERD- HRQL questionnaires were significantly reduced between pre-OAGB and post-OAGB: Symptoms (20; 62.5% vs 10; 31.3%, p = 0.012), overall score (15 (0-39) vs 7 (0-28), p = 0.04) and subjective improvement (10; 31% vs 20; 62.5%, p = 0.025). CONCLUSION: Conversion of LSG to OAGB showed subjective improvement of GERD symptoms both in RDQ and in GERD-HRQL.

BACKGROUND: The neutrophil to lymphocyte ratio (NLR) has demonstrated prognostic value in various malignant conditions, including gastric adenocarcinoma. However, chemotherapy may affect NLR. OBJECTIVES: To evaluate the prognostic value of NLR as an accessory decision-making tool in terms of operating patients after neoadjuvant chemotherapy in patients with resectable gastric cancer. METHODS: We collected oncologic, perioperative, and survival data of patients with gastric adenocarcinoma who underwent curative intent gastrectomy and D2 lymphadenectomy between 2009 and 2016. The NLR was calculated from preoperative laboratory tests and classified as high (> 4) and low (≤ 4). The t-test, chi-square, Kaplan-Meier analysis, and Cox multivariate regression models were used to assess associations of clinical, histologic, and hematological variables with survival. RESULTS: For 124 patients the median follow-up was 23 months (range 1-88). High NLR was associated with greater rate of local complication (r=0.268, P < 0.01). The rate of major complications (Clavien-Dindo ≥ 3) was higher in the high NLR group (28% vs. 9%, P = 0.022). Among the 53 patients who received neoadjuvant chemotherapy, those with low NLR had significantly improved disease-free survival (DFS) (49.7 vs. 27.7 months, P = 0.025). Low NLR was not significantly associated with overall survival (mean survival, 51.2 vs. 42.3 months, P = 0.19). Multivariate regression identified NLR group (P = 0.013), male gender (P = 0.04), and body mass index (P = 0.026) as independently associated with DFS. CONCLUSIONS: Among gastric cancer patients planned for curative intent surgery who underwent neoadjuvant chemotherapy, NLR may have prognostic value, particularly regarding DFS and postoperative complications.

BACKGROUND: Small-bowel obstruction (SBO) after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is a common complication associated with re-admission that may alter patients' outcomes. Our aim was to characterize and investigate the impact of bowel obstruction on patients' prognosis. METHODS: This was a retrospective analysis of patients with SBO after CRS/HIPEC (n = 392). We analyzed patients' demographics, operative and perioperative details, SBO re-admission data, and long-term oncological outcomes. RESULTS: Out of 366 patients, 73 (19.9%) were re-admitted with SBO. The cause was adhesive in 42 (57.5%) and malignant (MBO) in 31 (42.5%). The median time to obstruction was 7.7 months (range, 0.5-60.9). Surgical intervention was required in 21/73 (28.7%) patients. Obstruction eventually resolved (spontaneous or by surgical intervention) in 56/73 (76.7%) patients. Univariant analysis identified intraperitoneal chemotherapy agents: mitomycin C (MMC) (HR 3.2, p = 0.003), cisplatin (HR 0.3, p = 0.03), and doxorubicin (HR 0.25, p = 0.018) to be associated with obstruction-free survival (OFS). Postoperative complications such as surgical site infection (SSI), (HR 2.2, p = 0.001) and collection (HR 2.07, p = 0.015) were associated with worse OFS. Multivariate analysis maintained MMC (HR 2.9, p = 0.006), SSI (HR 1.19, p = 0.001), and intra-abdominal collection (HR 2.19, p = 0.009) as independently associated with OFS. While disease-free survival was similar between the groups, overall survival (OS) was better in the non-obstruction group compared with the obstruction group (p = 0.03). CONCLUSIONS: SBO after CRS/HIPEC is common and complex in management. Although conservative management was successful in most patients, surgery was required more frequently in patients with MBO. Patients with SBO demonstrate decreased survival.

BACKGROUND: Minimally invasive parathyroidectomy (MIP) has gained acceptance as the preferred surgical procedure for management of primary hyperparathyroidism (pHPT). Appropriate selection of patients for a MIP is a crucial step in its utilization. The aim of the study was to evaluate the role of 18F-FCH PET/CT as second-line imaging for accurately directing MIP. METHODS: This is a retrospective single-center study. Seventy-two patients with biochemical evidence of pHPT and a non-conclusive or negative first-line imaging (ultrasound and dual isotope subtraction scintigraphy) received 18F-FCH PET/CT between January 2018 and February 2020. All imaging studies were performed at our institution. Assessment of therapeutic changes and outcomes was performed. RESULTS: of the 72 patients imaged with 18F-FCH PET/CT, 54 subsequently underwent parathyroidectomy. When considering the ability of 18F-FCH PET/CT alone to predict a uniglandular disease, the sensitivity, specificity, PPV and NPV were 92.7% (95%CI: 80.1-98.5), 46.2% (19.2-74.9), PPV 87.3% (80.5-92) and NPV 61.2% (31.4-84.5), respectively. When we combined the data provided by 18F-FCH PET/CT with the data already collected from 1st line imaging we were able to complete a minimally invasive surgery in 38 of the 41 (92%) patients with a uniglandular disease. Thirteen patients (24%) had a multiglandular disease, all of them except one underwent bilateral neck exploration based on the data collected by all imaging modalities combined. Overall, cure was achieved in 53 (98%) patients. CONCLUSION: 18F-FCH PET/CT, interpreted along with first-line imaging results in selected patients, can better facilitate utilization of MIS while maintaining exceptional cure rates.

BACKGROUND: Bariatric patients have a high prevalence of hiatal hernia (HH). HH imposes various difficulties in performing laparoscopic bariatric surgery. Preoperative evaluation is generally inaccurate, establishing the need for better preoperative assessment. OBJECTIVE: To utilize machine learning ability to improve preoperative diagnosis of HH. METHODS: Machine learning (ML) prediction models were utilized to predict preoperative HH diagnosis using data from a prospectively maintained database of bariatric procedures performed in a high-volume bariatric surgical center between 2012 and 2015. We utilized three optional ML models to improve preoperative contrast swallow study (SS) prediction, automatic feature selection was performed using patients' features. The prediction efficacy of the models was compared to SS. RESULTS: During the study period, 2482 patients underwent bariatric surgery. All underwent preoperative SS, considered the baseline diagnostic modality, which identified 236 (9.5%) patients with presumed HH. Achieving 38.5% sensitivity and 92.9% specificity. ML models increased sensitivity up to 60.2%, creating three optional models utilizing data and patient selection process for this purpose. CONCLUSION: Implementing machine learning derived prediction models enabled an increase of up to 1.5 times of the baseline diagnostic sensitivity. By harnessing this ability, we can improve traditional medical diagnosis, increasing the sensitivity of preoperative diagnostic workout.

BACKGROUND: Synchronous peritoneal and liver metastasis in colorectal cancer is a relative contraindication for curative surgery. We aimed to evaluate the safety and oncological outcomes of combined treatment of peritoneal and liver metastasis. METHODS: We conducted a retrospective analysis of metastatic colorectal cancer patients from two prospective databases: peritoneal surface malignancy (n = 536) and hepatobiliary (n = 286). We compared 60 patients treated with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) and hepatectomy; 80 patients treated with cytoreduction and HIPEC only; and 63 patients treated with hepatectomy alone. RESULTS: No differences in demographics were observed between the groups. Median hospital and intensive care unit (ICU) stay was shorter in group C (7 and 1 days, respectively) versus groups A and B (13 and 1 days, and 12 and 1 days, respectively; p < 0.001). Postoperative complications were not significantly different. Median follow-up was 18.6, 23.1, and 30.6 months for groups A, B, and C, respectively. Estimated 5-year overall survival (OS) was 48.8% (group A), 55.4% (group B), and 60.2% (group C) [p = 0.043 for group A vs. group C], and estimated 5-year disease-free survival (DFS) was 14.2% (group A), 23.0% (group B), and 18.6% (group C). Five-year OS was superior in group C compared with group A (p = 0.043), and DFS was superior in group C compared with groups A and B (p = 0.043 and 0.03, respectively). The peritoneum was the site of first recurrence in groups A and B (23.3% and 32.5%, respectively), and the liver was the site of first recurrence in group C (44.4%). CONCLUSIONS: We report favorable perioperative and oncological outcomes in combined cytoreduction/HIPEC and hepatectomy for patients with peritoneal and liver metastasis. Surgical intervention after multidisciplinary discussion should be considered in patients with both peritoneal and hepatic lesions when complete cytoreduction is feasible.

BACKGROUND: Pathological response of colorectal peritoneal metastasis (CRPM) may affect prognosis. We investigated the relationship between oncological outcomes and pathological response to chemotherapy of CRPM following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: We conducted a retrospective analysis of a prospectively maintained Peritoneal Surface Malignancies database between 2015 and 2020. Analysis included patients with CRPM who underwent a CRS/HIPEC procedure (n = 178). The cohort was divided into three groups according to the response ratio (ratio of tumor-positive specimens to the total number of specimens resected): Group A, complete response; Group B, high response ratio, and Group C, low response ratio. RESULTS: The group demographics were similar, but the overall complication rate was higher in Group C (65.2%) compared with Groups A (55%) and B (42.8%) [p = 0.03]. Survival correlated to response ratio; the estimated median disease-free survival of Group C was 9.1 months (5.97-12.23), 14.9 months (4.72-25.08) for Group B, and was not reached in Group A (p = 0.001). The estimated median overall survival in Group C was 35 months (26.69-43.31), and was not reached in Groups A and B (p = 0.001). CONCLUSIONS: The pathological response ratio to systemic therapy correlates with survival in patients undergoing CRS/HIPEC. This study supports the utilization of preoperative therapy for better patient selection, with a potential impact on survival.

BACKGROUND: As part of the effort to control the coronavirus disease-19 (COVID-19) outbreak, strict emergency measures, including prolonged national curfews, have been imposed. Even in countries where healthcare systems still functioned, patients avoided visiting emergency departments (EDs) because of fears of exposure to COVID-19. OBJECTIVES: To describe the effects of the COVID-19 outbreak on admissions of surgical patients from the ED and characteristics of urgent operations performed. METHODS: A prospective registry study comparing all patients admitted for acute surgical and trauma care between 15 March and 14 April 2020 (COVID-19) with patients admitted in the parallel time a year previously (control) was conducted. RESULTS: The combined cohort included 606 patients. There were 25% fewer admissions during the COVID-19 period (P < 0.0001). The COVID-19 cohort had a longer time interval from onset of symptoms (P < 0.001) and presented in a worse clinical condition as expressed by accelerated heart rate (P = 0.023), leukocyte count disturbances (P = 0.005), higher creatinine, and CRP levels (P < 0.001) compared with the control cohort. More COVID-19 patients required urgent surgery (P = 0.03) and length of ED stay was longer (P = 0.003). CONCLUSIONS: During the COVID-19 epidemic, fewer patients presented to the ED requiring acute surgical care. Those who did, often did so in a delayed fashion and in worse clinical condition. More patients required urgent surgical interventions compared to the control period. Governments and healthcare systems should emphasize to the public not to delay seeking medical attention, even in times of crises.

(1) Background: Crohn's disease (CD) and right-sided colorectal-carcinoma (CRC) are two common indications for right colectomies. Many studies have tried to identify risk factors associated with post-operative complications for both CD and CRC. However, data directly comparing the outcomes of the two are sparse. This study aims to compare the 30-day post-operative outcome after a right colectomy for CD versus CRC. Its secondary aim is to identify the factors associated with these outcomes for each group. (2) Methods: A retrospective cohort study of 123 patients who underwent a right colectomy for CD or CRC in a single institution between March 2011 and March 2016. (3) Results: There were no significant differences between the groups when comparing the overall complication rate, the median Clavien-Dindo score, reoperation rates and the length of hospitalization. The leak rate was higher in the Crohn's group (13.95% (6/43) vs. 3.75% (3/80)), p = 0.049), although the stoma rate was the same (4/43 9.5%; 7/80 9.9%). (4) Conclusions: This study has shown that post-operative complication rate is similar for right colectomy in CD and CRC. However, Crohn's disease patients did have a higher leak rate.
RESUMO
BACKGROUND: Textbook oncologic outcome (TOO) is a composite metric shown to correlate with improved survival after curative intent oncologic procedures. Despite increasing use among disciplines in surgical oncology, no consensus exists for its definition in cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). STUDY DESIGN: An international consensus-based study employed a Delphi methodology to achieve agreement. Fifty-four senior surgeons from the peritoneal surface malignancies field received a questionnaire comprising TOO parameters divided into 3 surgical domains: operative, short-term, and long-term postoperative outcomes. Two online meetings with participants defined the new criteria. Consensus was achieved when 75% of agreement rate was reached. Clinical data of patients who underwent CRS and HIPEC for colorectal peritoneal metastasis between 2010 and 2022 from 1 designated center (Sheba Medical Center) were collected, the consensus definition applied and outcomes analyzed. RESULTS: Thirty-eight surgeons (70%) participated. Expert consensus TOO parameters for colorectal peritoneal metastasis CRS and HIPEC included the absence of unplanned reoperations during 30 days postoperation, absence of severe postoperative complications (Clavien-Dindo ≥III), absence of unplanned readmissions during 30 days postoperation, 90-day postoperative mortality, and absence of contraindications for chemotherapy within 12 weeks from operation, and included the achievement of complete cytoreduction (CC0). The study cohort consisted of 251 patients, and 151 (60%) met TOO criteria. Patients who achieved TOO had significantly better overall survival (median 67.5 months, 95% CI) vs patients who did not achieve TOO (median 44.6 months, 95% CI, p < 0.001) and significantly improved disease-free survival (median, 12 months, 95% CI, vs 9 months, 95% CI, p = 0.01). CONCLUSIONS: Achievement of TOO as defined by consensus statement is associated with improved survival.

BACKGROUND: Surgical resection in Crohn's disease is sometimes the only alternative treating disease complications or refractory disease. The implications of early resection on disease course are still debatable. We aimed to assess the influence of preoperative disease duration on long-term postoperative disease course. METHODS: A retrospective analysis of all Crohn's disease patients who underwent an elective primary ileocolic resection between 2010 and 2021 in a single tertiary medical center. The cohort was divided based on disease duration, Group A (47 patients) had a disease duration shorter than 3 years (median of 1 year) and Group B (139 patients) had a disease duration longer than 3 years (median of 11 years). RESULTS: Surgeries were less complex among Group A as noted by higher rates of laparoscopic assisted procedures (68.1% vs. 45.3%, P = 0.006), shorter surgery duration (134 vs. 167 min, P < 0.0001) less estimated blood loss (72.5 vs. 333 mL, P = 0.016) and faster return of bowel function (3 vs. 4 days, P = 0.011). However, propensity score matching nullified all the differences. Younger age (OR = 0.86, P = 0.004), pre-op steroids (OR = 3.69, P = 0.037) and longer disease duration (OR = 1.18, P = 0.012) were found to be independently significantly associated with severe complications. After a median follow-up time of 71.38 months no significant differences were found between the groups in terms of endoscopic (P = 0.59), or surgical recurrences rates (P = 0.82). CONCLUSIONS: The main effect of preoperative short disease duration was noted within the surgical complexity; however, matching suggests confounders as cause of the difference. No significant long-term implication was noted on disease recurrence.

The purpose of this study was to evaluate the quality of life (QoL), early post-operative complications, and hernia recurrence rate following laparoscopic enhanced-view Totally Extra-Peritoneal (eTEP) Rives-Stoppa (RS) for incisional and primary ventral hernia repair. Retrospective review of a prospectively maintained database of all patients undergoing eTEP-RS between 2017 and 2020. Data retrieved included demographics, and clinical and operative variables. QoL was assessed using the EuraHS-QoL scale prior to- and following eTEP-RS. During the study period, 61 patients met the inclusion criteria. Age and BMI were 62 (60.4 ± 13.8) years and 29.7 (30.4 ± 6) kg/m2, respectively. Incisional hernia was the most common pathology (n = 40, 65%) followed by primary ventral hernia (n = 21, 35%), with 24 patients (39%) having a previous hernia repair. Diastasis-recti repair was undertaken in 34 patients (55%), a concomitant inguinal hernia was repaired in 6 patients (10%), and 13 patients (21%) underwent transversus abdominis release (TAR). Median follow-up time was 13 months and 15 patients (25%) had at least 2 years of follow-up. Hernia recurrence was found in 4 patients (6.5%). Pre-operative and post-operative EuraHS-QOL questionnaire scores were available for 46 patients (75%) and showed significant improvement in pain (7 vs. 0.5, p < 0.0001; 5 vs. 0.5, p < 0.0001; 5 vs. 1.5; p < 0.006), restrictions (median of 5 vs. 0.5, p < 0.0001; 5 vs. 0, p < 0.0001; median of 5 vs. 1, p < 0.0001, of 6.5 vs. 1.5, p < 0.0001), and cosmetic appearance (8 vs. 4, p < 0.0001). Abdominal wall repair using the eTEP-RS approach significantly improves subjective QoL variables with an acceptable post-operative complications and hernia recurrence rates in a short-term follow-up.

PURPOSE: One of the most common ileostomy-related complications is high output stoma (HOS) which causes significant fluids and electrolytes disturbances. We aimed to analyze the incidence, severity, and risk factors for readmission for HOS. METHODS: We reviewed all patients who underwent loop ileostomy closure in a single institution between 2010 and 2020. Patients that were readmitted for dehydration due to HOS during the time interval between the creation and the closure of the stoma were identified and divided into a study (HOS) group. The remaining patients constructed the control group. RESULTS: A total of 307 patients were included in this study, out of which, 41 patients were readmitted 73 times (23.7% readmission rate) for the HOS group, and the remaining 266 patients constructed the control group. Multivariate analysis identified; advanced American Society of Anesthesiologists (ASA) physical status (PS) classification, elevated baseline creatinine, and open surgery as risk factors for HOS. Renal function worsened among the entire cohort between the construction of the stoma to its closure (mean creatinine of 0.82 vs. 0.96, P<0.0001). CONCLUSION: Loop ileostomy formation is associated with a substantial readmission rate for dehydration as a result of HOS, and increasing the risk for renal impairment during the duration of the diversion. We identified advanced ASA PS classification, open surgery, and elevated baseline creatinine as predictors for HOS.
RESUMO
BACKGROUND: Discrimination between adrenocortical carcinoma and lipid-poor cortical adenoma preoperatively is frequently difficult as these two entities have overlapping imaging characteristics. Differentiation will allow for the selection of the most appropriate operative approach and may help prevent over-treatment. We aimed to identify imaging features that could preoperatively differentiate adrenocortical carcinoma from lipid-poor cortical adenoma and use them in a novel imaging-based score. METHODS: We conducted a retrospective analysis of patients with pathologically proven adrenocortical carcinoma and lipid-poor cortical adenoma who underwent resection in a single tertiary referral center between March 1998 and August 2020. The inclusion criteria were diameter >1 cm, attenuation >10 Hounsfield units on nonenhanced computed tomography, and histopathologic diagnosis. Patients with metastatic or locally advanced adrenocortical carcinoma adenoma (stages 3-4) were excluded. We developed a score using binary logistic multivariate regression model in 5-fold derivation (â¼70%) cohorts with stepwise backward conditional regression as feature selection. Standardized mean regression weight was used as variable score points. RESULTS: We identified 232 adrenals resected across 211 patients. By comparing the imaging characteristics of adrenocortical carcinoma (n = 56) and lipid-poor cortical adenoma (n = 156), we revealed statistically significant differences between the groups in 9 parameters: size, attenuation, thin and thick rim enhancement patterns, heterogeneity, calcification, necrosis, fat infiltration, and lymph node prominence. The score mean performance was 100% sensitivity for the exclusion of adrenocortical carcinoma, 80% specificity (95% confidence interval, 68.3-91.5), 66% positive predictive value (95% confidence interval, 52.3-78.7), and 100% negative predictive value with area under the curve of 0.974. CONCLUSION: We defined and evaluated a novel 9-variable, imaging-based score. This score outperformed any single variable and could facilitate safe preoperative discrimination of adrenocortical carcinoma and lipid-poor cortical adenoma.

BACKGROUND: The peritoneum is a common metastatic site of colorectal cancer (CRC) and associated with worse oncological outcomes. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) has been shown to improve outcomes in selected patients. Studies have demonstrated significant difference in survival of patients with primary colon and rectal tumors both in local and in metastatic setting; but only few assessed outcomes of CRS/HIPEC for rectal and colon tumors. We studied the perioperative and oncological outcomes of patients undergoing CRS/HIPEC for rectal cancer. METHODS: A retrospective analysis of a prospectively maintained database between 2009 and 2021 was performed. RESULTS: 199 patients underwent CRS/HIPEC for CRC. 172 patients had primary colon tumors and 27 had primary rectal tumors. Primary rectal location was associated with longer surgery (mean 4.32, hours vs 5.26 h, p = 0.0013), increased blood loss (mean 441cc vs 602cc, p = 0.021), more blood transfusions (mean 0.77 vs 1.37units, p = 0.026) and longer hospitalizations (mean 10 days vs 13 days, p = 0.02). Median disease-free survival (DFS) was shorter in rectal primary group; 7.03 months vs 10.9 months for colon primaries (p = 0.036). Overall survival was not statistically significant; 53.2 months for rectal and 60.8 months for colon primary tumors. Multivariate analysis indicated origin (colon vs rectum) and Peritoneal Cancer Index to be independently associated with DFS. CONCLUSIONS: Patients with rectal carcinoma undergoing CRS/HIPEC for peritoneal metastasis had worse peri-operative and oncological outcomes. Overall survival was excellent in both groups. This data may be used for risk stratification when considering CRS/HIPEC for patients with rectal primary.
