Abstract
The solitary fibrous tumor (SFT) is usually described as a lesion arising from the pleura. Rarely, it has been described in the parapharyngeal space (PS). This study aims to report two cases of SFT in the PS and to perform a literature review on this topic. Two patients undergoing surgical resection of a SFT in the PS, were reported. A literature review on SFT of the PS, was also performed. Two patients were analyzed. Both patients underwent surgical resection, followed by adjuvant radiotherapy, for SFT arising from the PS. The postoperative course was uneventful and both patients recovered well after the procedure. No recurrences were diagnosed during the followup. SFT of the PS is an infrequent entity. Surgical resection is the most used treatment, and adjuvant radiation should be considered in patients with recurrence risk factors or distant metastases.

Abstract
BACKGROUND We aimed to analyze and compare the timing and patterns of treatment failure, and survival after progression between HPV-positive (HPV+) and HPV-negative (HPV-) patients undergoing chemoradiation for oropharyngeal squamous cell carcinomas (OPSCC). METHODS A retrospective review was performed of all patients undergoing primary chemoradiation for OPSCC between 2008 and 2021. Demographic and clinical data were collected. Kaplan-Meier estimates for overall survival (OS), and time to recurrence/metastases (TTR) were compared using the log-rank test, with Cox regression used for multivariable modeling comparing HPV+ and HPV- patients. RESULTS HPV- patients developed recurrence or metastases at earlier time points than HPV+ patients (8.8 vs. 15.2 months, p < 0.05), due to earlier local/locoregional recurrence and distant metastases, but not isolated regional recurrences. HPV- distant metastases exclusively occurred in a single organ, most commonly the lungs or bone, while HPV+ metastases frequently had multi-organ involvement in a wide variety of locations (p < 0.05). Once progression (recurrence/metastases) was diagnosed, HPV+ patients experienced superior survival to HPV- patients on univariate and multivariate analysis, largely due to improved outcomes after treatment of local/locoregional recurrences (p < 0.05). There were no differences in survival after isolated regional recurrences or distant metastases. CONCLUSION HPV+ OPSCC patients relapse later compared to HPV- patients in local/locoregional and distant sites. HPV+ patients with local/locoregional recurrence experience superior survival after recurrence, which does not hold true for isolated regional recurrences or distant metastases. These data can be useful to inform prognosis and guide treatment decisions in patients with recurrent OPSCC.

Abstract
BACKGROUND Adverse pathological features following surgery in head and neck squamous cell carcinoma (HNSCC) are strongly associated with survival and guide adjuvant therapy. We investigated molecular changes associated with these features. METHODS We downloaded data from the Cancer Genome Atlas and Cancer Proteome Atlas HNSCC cohorts. We compared tumors positive versus negative for perineural invasion (PNI), lymphovascular invasion (LVI), extracapsular spread (ECS), and positive margins (PSM), with multivariable analysis. RESULTS All pathological features were associated with poor survival, as were the following molecular changes: low cyclin E1 (HR = 1.7) and high PKC-alpha (HR = 1.8) in tumors with PNI; six of 13 protein abundance changes with LVI; greater tumor hypoxia and high Raptor (HR = 2.0) and Rictor (HR = 1.6) with ECS; and low p38 (HR = 2.3), high fibronectin (HR = 1.6), low annexin A1 (HR = 3.1), and high caspase-9 (HR = 1.6) abundances with PSM. CONCLUSIONS Pathological features in HNSCC carry specific molecular changes that may explain their poor prognostic associations.

Abstract
Background: There are a number of nerve grafting options for facial reanimation and the ansa hypoglossi (AH) may be considered in select situations. Objective: To compare axonal density, area, and diameter of AH with other nerves more usually used for facial reanimation. Methods: AH specimens from patients undergoing neck dissections were submitted in formalin. Proximal to distal cross sections, nerve diameters, and the number of axons per nerve, proximally and distally, were measured and counted. Results: Eighteen nerve specimens were analyzed. The average manual axon count for the distal and proximal nerve sections was 1378 ± 333 and 1506 ± 306, respectively. The average QuPath counts for the proximal and distal nerve sections were 1381 ± 325 and 1470 ± 334, respectively. The mean nerve area of the proximal and distal nerve sections was 0.206 ± 0.01 and 0.22 ± 0.064 mm2, respectively. The mean nerve diameter for the proximal and distal nerve sections were 0.498 ± 0.121 and 0.526 ± 0.75 mm, respectively. Conclusion: The histological characteristics of the AH support clinical examination of outcomes as a promising option in facial reanimation.

Abstract
Objectives Ultrasound-guided wire (USGW) localisation for small non-palpable tumours before a revision head and neck surgery is an attractive pre-operative option to facilitate tumour identification and decrease potential complications. We describe five cases of pre-operative USGW localisation of non-palpable head and neck lesions to facilitate surgical localisation and resection. Methods All patients undergoing pre-operative USGW localisation for non-palpable tumours of the head and neck region at London Health and Sciences Center, London, Ontario, Canada, were included. All the USGW localisations were performed by the same interventional radiologist, and the surgeries were performed by fellowship trained head and neck surgeons. Results Five patients were included. All patients were undergoing revision surgery for recurrent or persistent disease. All successfully underwent a pre-operative USGW localisation of the non-palpable lesion before revision surgery. All lesions were localised intra-operatively with no peri-operative complications. Conclusions USGW localisation is a safe and effective pre-operative technique for the identification of small non-palpable head and neck tumours.

Abstract
BACKGROUND The objective of this study was to examine the utility of postoperative radiation for low and intermediate grade cancers of the parotid and submandibular glands. METHODS The authors conducted a retrospective, Canadian-led, international, multi-institutional analysis of a patient cohort with low or intermediate grade salivary gland cancer of the parotid or submandibular gland who were treated from 2010 until 2020 with or without postoperative radiation therapy. A multivariable, marginal Cox proportional hazards regression analysis was performed to quantify the association between locoregional recurrence (LRR) and receipt of postoperative radiation therapy while accounting for patient-level factors and the clustering of patients by institution. RESULTS In total, 621 patients across 14 tertiary care centers were included in the study; of these, 309 patients (49.8%) received postoperative radiation therapy. Tumor histologies included 182 (29.3%) acinic cell carcinomas, 312 (50.2%) mucoepidermoid carcinomas, and 137 (20.5%) other low or intermediate grade primary salivary gland carcinomas. Kaplan-Meier LRR-free survival at 10 years was 89.0% (95% confidence interval [CI], 84.9%-93.3%). In multivariable Cox regression analysis, postoperative radiation therapy was independently associated with a lower hazard of LRR (adjusted hazard ratio, 0.53; 95% CI, 0.29-0.97). The multivariable model estimated that the marginal probability of LRR within 10 years was 15.4% without radiation and 8.8% with radiation. The number needed to treat was 16 patients (95% CI, 14-18 patients). Radiation therapy had no benefit in patients who had early stage, low-grade salivary gland cancer without evidence of nodal disease and negative margins. CONCLUSIONS Postoperative radiation therapy may reduce LLR in some low and intermediate grade salivary gland cancers with adverse features, but it had no benefit in patients who had early stage, low-grade salivary gland cancer with negative margins.

Abstract
BACKGROUND The role of proximal diversion in patients undergoing sigmoid resection and primary anastomosis for diverticulitis with generalized peritonitis is unclear. The aim of this study was to compare the clinical outcomes of sigmoid resection and primary anastomosis and sigmoid resection and primary anastomosis with a proximal diversion in perforated diverticulitis with diffuse peritonitis. METHOD A systematic literature search on sigmoid resection and primary anastomosis and sigmoid resection and primary anastomosis with proximal diversion for diverticulitis with diffuse peritonitis was conducted in the Medline and EMBASE databases. Randomized clinical trials and observational studies reporting the primary outcome of interest (30-day mortality) were included. Secondary outcomes were major morbidity, anastomotic leak, reoperation, stoma nonreversal rates, and length of hospital stay. A meta-analysis of proportions and linear regression models were used to assess the effect of each procedure on the different outcomes. RESULTS A total of 17 studies involving 544 patients (sigmoid resection and primary anastomosis: 287 versus sigmoid resection and primary anastomosis with proximal diversion: 257) were included. Thirty-day mortality (odds ratio 1.12, 95% confidence interval 0.53-2.40, P = .76), major morbidity (odds ratio 1.40, 95% confidence interval 0.80-2.44, P = .24), anastomotic leak (odds ratio 0.34, 95% confidence interval 0.099-1.20, P = .10), reoperation (odds ratio 0.49, 95% confidence interval 0.17-1.46, P = .20), and length of stay (sigmoid resection and primary anastomosis: 12.1 vs resection and primary anastomosis with diverting ileostomy: 15 days, P = .44) were similar between groups. The risk of definitive stoma was significantly lower after sigmoid resection and primary anastomosis (odds ratio 0.05, 95% confidence interval 0.006-0.35, P = .003). CONCLUSION Sigmoid resection and primary anastomosis with or without proximal diversion have similar postoperative outcomes in selected patients with diverticulitis and diffuse peritonitis. However, further randomized controlled trials are needed to confirm these results.

Abstract
Objective Airway fires are a rare but devastating complication of airway surgery. Although protocols for managing airway fires have been discussed, the ideal conditions for igniting airway fires remain unclear. This study examined the oxygen level required to ignite a fire during a tracheostomy. Study Design Porcine Model. Setting Laboratory. Methods Porcine tracheas were intubated with a 7.5 air-filled polyvinyl endotracheal tube. A tracheostomy was performed. Monopolar and bipolar cautery were used in independent experiments to assess the ignition capacity. Seven trials were performed for each fraction of inspired oxygen (FiO2): 1.0, 0.9, 0.7, 0.6, 0.5, 0.4, and 0.3. The primary outcome was ignition of a fire. The time was started once the cautery function was turned on. The time was stopped when a flame was produced. Thirty seconds was used as the cut-off for "no fire." Results The average time to ignition for monopolar cautery at FiO2 of 1.0, 0.9, 0.8, 0.7, and 0.6 was found to be 9.9, 6.6, 6.9, 9.6, and 8.4 s, respectively. FiO2 ≤ 0.5 did not produce a flame. No flame was created using the bipolar device. Dry tissue eschar shortened the time to ignition, whereas moisture in the tissue prolonged the time to ignition. However, these differences were not quantified. Conclusion Dry tissue eschar, monopolar cautery, and FiO2 ≥ 0.6 are more likely to result in airway fires.

Abstract
BACKGROUND There is significant interest in treatment de-escalation for human papillomavirus-associated (HPV+) oropharyngeal squamous cell carcinoma (OPSCC) patients given the generally favourable prognosis. However, 15-30% of patients recur after primary treatment, reflecting a need for improved risk-stratification tools. We sought to develop a molecular test to risk stratify HPV+ OPSCC patients. METHODS We created an immune score (UWO3) associated with survival outcomes in six independent cohorts comprising 906 patients, including blinded retrospective and prospective external validations. Two aggressive radiation de-escalation cohorts were used to assess the ability of UWO3 to identify patients who recur. Multivariate Cox models were used to assess the associations between the UWO3 immune class and outcomes. FINDINGS A three-gene immune score classified patients into three immune classes (immune rich, mixed, or immune desert) and was strongly associated with disease-free survival in six datasets, including large retrospective and prospective datasets. Pooled analysis demonstrated that the immune rich group had superior disease-free survival compared to the immune desert (HR = 9.0, 95% CI: 3.2-25.5, P = 3.6 × 10-5) and mixed (HR = 6.4, 95% CI: 2.2-18.7, P = 0.006) groups after adjusting for age, sex, smoking status, and AJCC8 clinical stage. Finally, UWO3 was able to identify patients from two small treatment de-escalation cohorts who remain disease-free after aggressive de-escalation to 30 Gy radiation. INTERPRETATION With additional prospective validation, the UWO3 score could enable biomarker-driven clinical decision-making for patients with HPV+ OPSCC based on robust outcome prediction across six independent cohorts. Prospective de-escalation and intensification clinical trials are currently being planned. FUNDING CIHR, European Union, and the NIH.

Abstract
Background Squamous cell carcinoma is the most common malignancy of the oral cavity. Primary treatment involves surgical resection of the tumour with a surrounding margin. Historically, the most commonly accepted margin clearance is 5 mm. This distance is controversial, with recent publications suggesting closer margins do not impact local recurrence and survival. The objective of this study is to determine the closest surgical margin that does not impact local recurrence and overall survival.
Methods A retrospective review of the London Health Sciences Centre Head and Neck Multidisciplinary Clinic between 2010 and 2018 was performed. Demographic data, subsite, tumour staging, treatment modality, margins, and survival outcomes were analyzed. The primary endpoint was local recurrence free survival. Secondary endpoints included recurrence-free survival and overall survival. Descriptive statistics, as well as univariable and multivariable Cox proportional hazards regression modelling were performed for all patients.
Results Four-hundred and twelve patients were included in the study, with a median follow-up of 3.3 years. On univariable analysis, positive margins and margins < 1 mm were associated with significantly worse local recurrence-free survival, recurrence-free survival, and overall survival (p < 0.05), compared to margins > 5 mm. Patients with surgical margins > 1 mm experienced similar outcomes to those with margins > 5 mm. Multivariable analysis identified age of diagnosis, alcohol consumption, pathological tumour and nodal category as predictors of local recurrence free survival. Conclusions Although historical margins for head and neck surgery are 5 mm, similar outcomes were observed for margins greater than 1 mm in our cohort. These findings require validation through multi-institutional collaborative efforts. Graphical abstract ![]()

Abstract
OBJECTIVE We aimed to analyze risk factors associated with poor survival outcomes for metastatic cutaneous head-and-neck SCC to the parotid. METHODS All patients undergoing surgery for metastatic cutaneous SCC to the parotid with curative intent between 2011 and 2018, were reviewed. Demographic and clinical characteristics were evaluated. Histopathological data including tumor size and histology, tumor grade, TNM stage, resection margins, lymphovascular invasion, and perineural invasion, were analyzed. Overall survival (OS), disease-specific survival (DSS), and freedom from locoregional recurrence (LRR) were assessed. RESULTS Ninety patients were included (mean age, 77 years; 75 men [83.3%]). A total parotidectomy was performed in 48 patients (53.3%), and 42 (46.7%) underwent a superficial parotidectomy. Seventy patients (77.8%) underwent adjuvant RT. The median follow-up was 31 months (20-39 months). Tumor volume ≥ 50 cm3 and a shorter RT duration (<20 days) were associated with reduced OS (p = 0.002 and p = 0.01, p = 0.02 and p = 0.009, respectively), and DSS (p = 0.004 and p = 0.02, p = 0.04 and p = 0.02, respectively) on univariable and multivariable analysis, respectively. Only a shorter RT duration was associated with worse freedom from LRR on univariable and multivariable analysis, (p = 0.04 and p < 0.001, respectively). However, with death as a competing risk, a shorter duration of RT was not significantly associated with freedom from LRR. CONCLUSION A shorter duration of adjuvant RT, and excised tumor volume ≥50 cm3 were predictive factors of reduced OS and DSS, and a shorter duration of RT was also associated with reduced freedom from LRR in patients with metastatic SCC to the parotid gland.

Abstract
BACKGROUND Neck carcinoma of unknown primary (CUP) is a frequent scenario. Transoral robotic mucosectomies (TORM) of pharynx have increased rate of primary identification, but come with cost of treatment delay. METHODS We reviewed patients who underwent CUP protocol from 2014 to 2020. Patients with cervical nodes carcinoma and failure to localize a primary source were classified as CUP. We determined primary identification rate and postoperative complications. RESULTS We included 65 patients underwent TORM. Surgical approach consisted of lingual and/or palatine tonsillectomies. The primary detection rate was 49.2%. Average weight reduction was 2.5 ± 4.3 kg. The average number of days from consultation to definitive treatment was 52.2 ± 18.3. CONCLUSION A systematic approach to patients with CUP showed a promising primary identification rate compared to panendoscopy alone. TORM carries a small risk of complications. The benefits of primary identification must be weighed with the morbidity and delay to definitive treatment.

Abstract
Background: As laparoscopic colorectal surgery (LCS) continues increasing worldwide, surgeons may need to perform more than one LCS per day to accommodate this higher demand. We aimed to determine the safety of performing consecutive LCSs by the same surgeon in a single workday. Materials and Methods: Consecutive LCSs performed by the same surgeon from 2006 to 2019 were included. The sample was divided into two groups: patients who underwent the first (G1) and those who underwent the second and the third (G2) colorectal resections in a single workday. LCSs were stratified into level I (low complexity), level II (medium complexity), and level III (high complexity). Demographics, operative variables, and postoperative outcomes were compared between groups. Results: From a total of 1433 LCSs, 142 (10%) were included in G1 and 158 (11%) in G2. There was a higher rate of complexity level III LCS (G1: 23% versus G2: 6%, P < .0001) and a longer operative time (G1: 160 minutes versus G2: 139 minutes, P = .002) in G1. There were no differences in anastomotic leak, overall morbidity, or mortality rates. Mean length of hospital stay and readmission rates were similar between groups. Conclusion: Multiple consecutive laparoscopic colorectal resections can be safely performed by the same surgeon in a single workday. This efficient strategy should be encouraged at high-volume centers with experienced colorectal surgeons.

Abstract
INTRODUCTION We aim to determine the utility of intraoperative parathyroid hormone (IOPTH) monitoring in patients with matching preoperative ultrasound and mibi SPECT for primary hyperparathyroidism for a single adenoma. METHODS All patients who underwent minimally invasive parathyroidectomy (MIP) for pseudohypoparathyroidism (PHP) for a single parathyroid adenoma, were included. An Ultrasound and mibi SPECT were performed in all patients. We defined matching studies when both coincided in the localization of the adenoma. IOPTH was performed in all patients and analyzed in three occasions: a baseline measurement at the anesthetic induction, immediately before, and 15 min after gland excision. Success was defined during the third measurement as a drop of IOPTH of at least 50% compared to the previous maximum value after gland excision. Demographics, intraoperative, postoperative variables and the utility of IOPTH monitoring were analyzed. RESULTS A total of 218 MIP were performed. The average age was 60.1 years and 85% were female. Preoperative ultrasound and mibi SPECT coincided 100%. When the adenoma was localized, 15 min after its excision, IOPTH did not decrease in 9 patients (4.2%. OR 1.9%-7.69%); all of them underwent a bilateral neck exploration. The added-value of IOPTH accuracy for disease cure was 3.6%. There was a 99% of cure rate. The mean surgical time was 66.4 min and the waiting time for the third IOPTH result was 31 min. Performing IOPTH monitoring made the surgery about twice more expensive. CONCLUSIONS Preoperative matching ultrasound and mibi SPECT for parathyroid adenoma localization in PHP, could avoid IOPTH monitoring in minimally invasive parathyroidectomies.

Abstract
Multimodal treatment is currently the standard of care for locally advanced esophagogastric junction (EGJ) adenocarcinoma due to poor results after surgery alone. Neoadjuvant therapy is intended to shrink the tumor and eliminate potential circulating tumor cells. However, which neoadjuvant treatment is best for patients with EGJ tumors remains controversial. We aimed to compare outcomes of preoperative chemoradiation and perioperative chemotherapy for EGJ adenocarcinomas. For this purpose, we performed a thorough review of the literature describing neoadjuvant treatments for EGJ adenocarcinomas or comparing both therapies. Although some studies have shown better locoregional control and higher rates of complete pathologic response after chemoradiation, data suggest that both types of neoadjuvant therapy have similar survival benefits. As current data are heterogeneous and many studies have included significantly different types of patients in their analysis, future studies with better patient selection are still needed to define which neoadjuvant therapy should be chosen. In addition, targeted therapies and immunotherapy have promising results and should be further explored.

Abstract
The use of mesh in laparoscopic hiatal hernia repair (LHHR) remains controversial. The aim of this systematic review was to determine the usefulness of mesh in patients with large hiatal hernia (HH), obesity, recurrent HH, and complicated HH. We performed a systematic review of the current literature regarding the outcomes of LHHR with mesh reinforcement. All articles between 2000 and 2020 describing LHHR with primary suturing, mesh reinforcement, or those comparing both techniques were included. Symptom improvement, quality of life (QoL) improvement, and recurrence rates were evaluated in patients with large HH, obesity, recurrent HH, and complicated HH. Reported outcomes of the use of mesh in patients with large HH had wide variability and heterogeneity. Morbidly obese patients with HH should undergo a weight-loss procedure. However, the benefits of HH repair with mesh are unclear in these patients. Mesh reinforcement during redo LHHR may be beneficial in terms of QoL improvement and hernia recurrence. There is scarce evidence supporting the use of mesh in patients undergoing LHHR for complicated HH. Current data are heterogeneous and have failed to find significant differences when comparing primary suturing with mesh reinforcement. Further research is needed to determine in which patients undergoing LHHR mesh placement would be beneficial.

Abstract
BACKGROUND As the prevalence of obesity continues to increase worldwide, we aimed to determine the surgical outcomes of obese patients with acute appendicitis undergoing laparoscopic appendectomy (LA). MATERIALS AND METHODS A retrospective analysis of patients undergoing LA during the period 2006 to 2019 was performed. The cohort was divided into 2 groups: G1, patients with body mass index ≥30 kg/m2 and G2: patients with body mass index <30 kg/m2. RESULTS A total of 2009 LA were performed; 114 (6%) were included in G1 and 1895 (94%) in G2. Complicated acute appendicitis rate (G1: 39% vs. G2: 20%, P<0.0001), conversion rates (G1: 12% vs. 1.69%, P<0.0001), overall 30-day morbidity rates (G1: 27% vs. G2: 14%, P=0.0001), and postoperative intra-abdominal abscess rates (G1: 8% vs. (2%), P<0.0001) were higher in obese patients. Furthermore, obesity was an independent risk factor for overall morbidity, postoperative intra-abdominal abscess, and conversion to open surgery. CONCLUSION In obese patients, LA had inferior clinical outcomes compared with nonobese patients.

Abstract
Despite laparoscopy is considered an adequate tool for the diagnosis and management of postoperative surgical complications, its role after laparoscopic appendectomy (LA) remains uncertain. The aim of this study was to evaluate whether laparoscopy is useful for treating complications after laparoscopic appendectomy. A retrospective analysis of a prospectively collected database of patients undergoing LA, who needed a reoperation for postoperative complications during the period 2006-2020, was performed. Demographics, operative variables, and postoperative outcomes were analyzed. A total of 2019 LA were performed, and 41 patients (2%) underwent a RL for post appendectomy complications. Twenty-three patients (56%) were male. The mean age was 32 years old (16-92 years). The majority of patients (75%) had a complicated acute appendicitis in the first operation. The most common findings at RL were generalized peritonitis (36.4%) and intraabdominal abscesses (26.8%). Five patients (12.1%) developed stump appendicitis, all of them as a late complication. The procedures were completed laparoscopically in 85% and 6 patients (15%) required conversion to an open approach. Three patients (7.3%) required a percutaneous drainage and two patients (4.9%) needed an additional surgery (laparotomy) after RL, all of them presenting with generalized peritonitis at the RL. No mortality was registered. Re-laparoscopy is feasible, safe, and highly effective for the diagnosis and treatment of post appendectomy complications. RL should be encouraged to avoid more aggressive procedures.

Abstract
PURPOSE Intraabdominal abscess (IAA) is a feared complication after laparoscopic appendectomy (LA) for complicated appendicitis. Benefits of obtaining intraoperative culture swabs (ICS) still remain controversial. We aimed to determine whether ICS modify the rate and management of IAA after LA for complicated appendicitis. METHODS A consecutive series of patients who underwent LA for complicated appendicitis from 2008 to 2018 were included. The cohort was divided into two groups: group 1 (G1), with ICS, and group 2 (G2), without ICS. Demographics, operative variables, pathogen isolation, antibiotic sensitivity, and postoperative outcomes were analyzed. RESULTS A total of 1639 LA were performed in the study period. Of these, 270 (16.5%) were complicated appendicitis; 90 (33%) belonged to G1 and 180 (67%) to G2. In G1, a higher proportion of patients had generalized peritonitis (G1, 63.3%; G2, 35%; p < 0.01). Seventy-two (80%) patients had positive cultures in G1. The most frequently isolated bacteria were E. coli (66.7%), Bacteroides spp. (34.7%), and Streptococcus spp. (19.4%). In 26 (36%) patients, the initial empiric antibiotic course was modified due to bacterial resistance. The rate of IAA was higher in patients with ICS (G1, 21.1%; G2, 9.4%; p = 0.01). IAA was treated similarly in both groups. A different type of bacteria was isolated in 7 (53.8%) patients with new culture swabs. CONCLUSIONS Obtaining ICS in LA for complicated appendicitis with further antibiotic adjustment to the initial pathogen did not lower the incidence of postoperative IAA and did not modify the treatment needed for this complication.

Abstract
BACKGROUND Postoperative intraabdominal abscess (IAA) is the most feared complication after laparoscopic appendectomy (LA). We aimed to evaluate the management of this complication in a large cohort of patients undergoing LA in order to design a treatment algorithm. METHODS We included a consecutive series of patients undergoing LA for acute appendicitis from January 2008 to December 2018. The cohort of patients with postoperative IAA was divided into three groups based on the implemented treatments: G1: antibiotics only, G2: CT-guided drainage, and G3: laparoscopic lavage. Characteristics of the fluid collections and outcomes were analyzed in the three groups. RESULTS A total of 1668 LA were performed; the rate of IAA was 2.2% (36 patients). There were 12 (33%) patients who received antibiotics only (G1), 8 (22%) underwent CT-guided percutaneous drainage (G2), and 16 (45%) underwent laparoscopic lavage (G3). The median size of the abscesses was 2.7 (1.2-4) cm in G1, 6.2 (4.5-8) cm in G2, and 9.6 (8-11.4) cm in G3 (p < 0.04). Patients with two or more fluid collections underwent a laparoscopic lavage in all cases. Treatment failure occurred in 16% (2/12), 12.5% (1/8) and 12.5% (2/16) of the patients in G1, G2, and G3, respectively. None of the patients in the entire cohort required open surgery to resolve the postoperative IAA. CONCLUSIONS A minimally invasive step-up approach based on the size and number of fluid collections is associated with excellent outcomes. A treatment algorithm for post-appendectomy IAA is proposed.

Abstract
Background: Laparoscopic Roux-en-Y gastric bypass (RYGB) is one of the most common procedures to treat morbid obesity. Abdominal drains are often placed during the operation to detect complications earlier. The aim of this study was to assess the benefit of routine drain placement during laparoscopic RYGB. Materials and Methods: A consecutive series of patients undergoing laparoscopic RYGB between 2017 and 2018 was analyzed. The sample was randomized before the procedure into two groups: with abdominal drain (G1) and without abdominal drain placement (G2). Patients with intraoperative complications were excluded from the randomization. Postoperative complications and pain (visual analogue scale) were compared between groups. Results: A total of 84 patients were included; 45 belonged to G1 and 39 to G2. Mean age (G1 44 years versus G2 48 years) and body mass index (G1 43 kg/m2 versus G2 44 kg/m2) were similar in both groups. There were no significant differences between groups in preoperative comorbidities. Mean operative time was 92 minutes in both groups. Mean pain score at postoperative day 0 was similar in both groups (G1 3.2 versus G2 3.5, P = .58), but was higher in G1 at postoperative day 1 (G1 3.1, G2 1.1, P = .02). Postoperative Clavien-Dindo I-II complications were similar in both groups (G1 9% versus G2 1%, P = .37). No major complications, reoperations, or 30-day mortality occurred in the entire cohort. Conclusions: Drain placement in laparoscopic RYGB was associated with greater postoperative pain and did not show benefits in early detection of postoperative complications. Routine placement of abdominal drain in laparoscopic RYGB might not be recommended.

Abstract
Pleomorphic adenoma is the most benign tumor of the salivary glands. It can undergo a malignant transformation to carcinoma and metastasize to distant organs, sometimes it can metastasize as a benign tumor. We present the case of an 82 years old male with hepatic lesion detected by ultrasound in routine urologic follow-up. CT scan revealed a solid image placed in segments V-VI-VII of the liver. A CT guided fine needle biopsy was made. Pathologic analysis reported a pleomorphic salivary adenoma metastasizing in the liver. Right hepatectomy was performed. Pathology study described a 10 cm diameter tumor with free margin, compatible with pleomorphic salivary adenoma, 32 years after surgery for the primary tumor. After 8 years of follow up, four hepatic nodules and a bone image in L4 vertebra that seemed to be a disease recurrence were found. It was decided to administer stereotactic body radiotherapy to the bone lesion and evaluate the response to decide the future treatment of the hepatic nodules, due to its slow growth.
