Effect of neoadjuvant chemoradiation on anorectal function assessed with anorectal manometry: A systematic review and meta-analysis.

AIM: Improvement in oncological survival for rectal cancer increases attention to anorectal dysfunction. Diagnostic questionnaires can evaluate quality of life but are subjective and dependent on patients' compliance. Anorectal manometry can objectively assess the continence mechanism and identify functional sphincter weakness and rectal compliance. Neoadjuvant chemoradiotherapy is presumed to affect anorectal function. We aim to assess anorectal function in rectal cancer patients who undergo total mesorectal excision, with or without neoadjuvant chemoradiation, using anorectal manometry measurements. METHOD: MEDLINE, Embase, and Cochrane databases were searched for studies comparing perioperative anorectal manometry between neoadjuvant chemoradiation and upfront surgery for rectal cancers. Primary outcomes were resting pressure, squeeze pressure, sensory threshold volume and maximal tolerable volume. RESULTS: Eight studies were included in the systematic review, of which seven were included for metanalysis. 155 patients (45.3%) had neoadjuvant chemoradiation before definitive surgery, and 187 (54.6%) underwent upfront surgery. Most patients were male (238 vs. 118). The standardized mean difference of mean resting pressure, mean and maximum squeeze pressure, maximum resting pressure, sensory threshold volume, and maximal tolerable volume favored the upfront surgery group but without statistical significance. CONCLUSION: Currently available evidence on anorectal manometry protocols failed to show any statistically significant differences in functional outcomes between neoadjuvant chemoradiation and upfront surgery. Further large-scale prospective studies with standardized neoadjuvant chemoradiation and anorectal manometry protocols are needed to validate these findings.

Comparative outcomes of Toupet fundoplication and magnetic sphincter augmentation.

Laparoscopic fundoplication is the current surgical gold standard for the treatment of refractory gastroesophageal reflux disease (GERD). Magnetic sphincter augmentation (MSA) is a less invasive, standardized, and reversible option to restore competency of the lower esophageal sphincter. A comparative cohort study was conducted at a tertiary-care referral center on patients with typical GERD symptoms treated with systematic crural repair combined with Toupet fundoplication or MSA. Primary study outcome was decrease of Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) score. Between January 2014 and December 2021, a total of 199 patients (60.3% female, median [Q1-Q3] age: 51.0 [40.0-61.0]) underwent MSA (n = 130) or Toupet fundoplication (n = 69). Operative time and hospital stay were significantly shorter in MSA patients (P < 0.0001). At a median follow-up of 12.0 [12.0-24.0] months, there was a statistically significant decrease of GERD-HRQL score in both patient groups (P = 0.001). The mean delta values did not significantly differ between groups (P = 0.7373). The incidence of severe gas bloating symptoms was similar in the two groups (P = 0.7604), but the rate of persistent postoperative dysphagia was greater in MSA patients (P = 0.0009). Six (8.7%) patients in the Toupet group had recurrent hiatal hernia requiring revisional surgery in one (1.4%). In the MSA group, eight (7.9%) patients necessitated through-the-scope balloon dilation for relief of dysphagia, and six patients had the device removed (4.6%) because of persistent dysphagia (n = 3), device disconnection (n = 1), persistent reflux (n = 1) or need of magnetic resonance (n = 1). Toupet and MSA procedures provide similar clinical outcomes, but MSA is associated with a greater risk of reoperation. Randomized clinical trials comparing fundoplication and MSA are eagerly awaited.

Minimally invasive esophagectomy for cancer in COVID hospitals and oncological hubs: are the outcomes different?

Introduction: The outbreak of coronavirus disease 2019 (COVID-19) has caused significant delays in oncological care worldwide due to restriction of elective surgery and intensive care unit capacity. It has been hypothesized that COVID-free oncological hubs can provide safer elective cancer surgery compared to COVID hospitals. The primary aim of the present study was to analyze the outcomes of minimally invasive esophagectomy for cancer performed in both hospital settings by the same surgical staff. Methods: All esophagectomies for cancer performed during the pandemic by a single team were reviewed and data were compared with control patients operated during the preceding year. Screening for severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) was performed prior to surgery, and special precautions were taken to mitigate hospital-related transmission of COVID-19 among patients and healthcare workers. Results: Compared to the prepandemic period, the esophagectomy volume decreased by 64%. Comorbidities, time from onset of symptoms to first visit, waiting time between diagnosis and surgery, operative approach and technique, and the pathological staging were similar. None of the patients tested positive for COVID-19 during in-hospital stay, and esophagectomy was associated with similar outcomes compared to control patients. Conclusion: Outcomes of minimally invasive esophagectomy for cancer performed in a COVID hospital after implementation of a COVID-free surgical pathway did not differ from those obtained in an oncological hub by the same surgical team.

Systemic metastases from low-grade and high-grade pseudomyxoma peritonei: Treatments and outcomes.

BACKGROUND: The metastasizing potential of pseudomyxoma peritonei (PMP) is largely unknown. We assessed incidence, impact on prognosis, treatments, and outcomes of systemic metastases after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). METHODS: A prospective database of 327 patients undergoing CRS/HIPEC for PMP of appendiceal origin was reviewed. PMP was graded according to the Peritoneal Surface Oncology Group International (PSOGI) classification. Haematogenous metastases, and non-regional lymph-node involvement were considered as systemic metastases. RESULTS: After a median follow-up of 74.8 months (95% confidence interval [CI] = 68.0-94.8), systemic metastases occurred in 21 patients. Eleven patients were affected by low-grade PMP, and ten by high-grade PMP. Metastatic disease involved the lung (n = 12), bone (n = 1), liver (n = 4), distant nodes (n = 3), both lung and distant nodes (n = 1). Systemic metastases independently correlated with PSOGI histological subtypes (P = 0.001), and incomplete cytoreduction (P = 0.026). Median OS was 139.0 months (95%CI = 56.6-161.9) for patients who experienced systemic metastases, and 213.8 months (95%CI = 148.7-not reached) for those who did not (P = 0.159). Eight of eleven patients who had curative-intent surgery are presently alive at a median of 52.5 months (range 2.0-112.7). Seven are disease-free at a median of 27.4 months (range 2.0-110.4). At multivariate analysis, PSOGI histological subtypes (P = 0.001), completeness of cytoreduction (P = 0.001), and preoperative systemic chemotherapy (P = 0.020) correlated with poorer survival. Systemic metastases did not (P = 0.861). CONCLUSIONS: After CRS/HIPEC, systemic metastases occur in a small but clinically relevant number of patients, and the risk increases with incomplete cytoreduction and aggressive histology. In selected patients, surgical resection of metastatic disease can result in long survival.

High-Pressure Tactics: Jackhammer Esophagus-Diagnosing Is Easier than Treating.

Diagnosis of esophageal disorders is well ahead of available treatment options. With HRM, for example, one can identify numerous conditions and their variants, which may lose meaning if the clinical and therapeutic implications of these subclassifications are limited. We report an exemplary case of a patient with hiatal hernia complaining of reflux, dysphagia, and chest pain refractory to medical treatment. Jackhammer esophagus was diagnosed and a hybrid approach consisting of POEM and concomitant crural repair and Dor fundoplication is proposed.

Ventral hernia repair under neuraxial anesthesia.

BACKGROUND: Acute strangulated ventral hernia is associated with operative morbidity and mortality. General anesthesia may increase the operative risk, especially in morbidly obese and COVID-19-positive individuals. METHODS: A 67-year-old woman with body mass index (BMI) 51 kg/m2, hospitalized for SARS-CoV-2-related interstitial pneumonia and renal failure, presented with acute abdominal pain, nausea, vomiting, and abdominal tenderness secondary to giant ventral hernia strangulation. RESULTS: Due to the suspicion of vascular bowel compromise at contrast-enhanced CT scan, urgent open surgical repair surgery was performed under spinal anesthesia and Venturi mask support. There was no need for an intensive care unit (ICU) stay. Postoperative course was uneventful, and the patient was transferred to a rehabilitation center on postoperative day 10. CONCLUSION: Although some anesthetists and surgeons may be reluctant to use regional anesthesia for both emergent and elective ventral hernia repair, this may represent an excellent option in obese patients with a high respiratory risk.

Revisional Therapy for Recurrent Symptoms After Heller Myotomy for Achalasia.

PURPOSE: Symptom recurrence after initial surgical management of esophageal achalasia occurs in 10-25% of patients. The aim of this study was to analyze safety and efficacy of revisional therapy after failed Heller myotomy (HM). METHODS: A retrospective review of a prospective database was performed searching for patients with recurrent symptoms after primary surgical therapy for achalasia. Patients with previously failed HM were considered for the final analysis. The Foregut questionnaire, and the Atkinson and Eckardt scales were used to assess severity of symptoms. Objective investigations routinely included upper gastrointestinal endoscopy and barium swallow study. Redo treatments consisted of endoscopic pneumatic dilation (PD), laparoscopic HM, hybrid Ivor Lewis esophagectomy, or stapled cardioplasty. A yearly clinical and endoscopic follow-up was scheduled in all patients. RESULTS: Over a 20-year period, 26 patients with a median age of 66 years (IQR 19.5) underwent revisional therapy after failed HM for achalasia at a tertiary-care university hospital. The median time after index procedure was 10 years (IQR 21). Revisional therapy consisted of endoscopic pneumatic dilation (n=13), laparoscopic HM and fundoplication (n=10), esophagectomy (n=2), and stapled cardioplasty and fundoplication (n=1). Nine (34.6%) of these patients required further endoscopic or surgical treatments. There was no mortality, and the overall complication rate was 7.7%. At a median follow-up of 42 months (range 10-149), a significant decrease of dysphagia, regurgitation, chest pain, respiratory symptoms, and median Eckardt score (p<0.05) was noted. CONCLUSION: In specialized and multidisciplinary centers, revisional therapy for achalasia is feasible, safe, and effective.

Dysphagia aortica.

Background: Dysphagia aortica is an umbrella term to describe swallowing obstruction from external aortic compression secondary to a dilated, tortuous, or aneurysmal aorta. We performed a systematic literature review to clarify clinical features and outcomes of patients with dysphagia aortica. Materials and methods: We searched PubMed, EMBASE, Web of Science, and the Cochrane Library. The terms "aortic dysphagia," "dysphagia aortica," "dysphagia AND aortic aneurysm" were matched. We also queried the prospectively updated database of our esophageal center to identify patients with aortic dysphagia referred for diagnosis and treatment over the past two decades. Results: A total of 57 studies including 69 patients diagnosed with dysphagia aortica were identified, and one patient from our center was added to the database. The mean age was 72 years (range 22-98), and the male to female ratio 1.1:1. Of these 70 patients, the majority (n = 63, 90%) had an aortic aneurysm, pseudoaneurysm, or dissection. Overall, 37 (53%) patients received an operative treatment (81.1% a vascular procedure, 13.5% a digestive tract procedure, 5.4% both procedures). Thoracic endovascular aortic repair (TEVAR) accounted for 60% of all vascular procedures. The postoperative mortality rate was 21.2% (n = 7/33). The mortality rate among patients treated conservatively was 55% (n = 11/20). Twenty-six (45.6%) studies were deemed at a high risk of bias. Conclusion: Dysphagia aortica is a rare clinical entity with high morbidity and mortality rates and no standardized management. Early recognition of dysphagia and a high suspicion of aortoesophageal fistula may be lifesaving in this patient population.

Falciform Ligament Flap as Crural Buttress in Laparoscopic Hiatal Hernia Repair.

Background: Crural repair is an essential technical component in laparoscopic hiatal hernia surgery, but there is no consensus regarding the optimal method to prevent postoperative hernia recurrence. Mesh augmentation, especially with permanent materials, is associated with dysphagia and complications. The rotational falciform ligament flap (FLF) has been reported to be effective in reinforcing standard suture closure of the hiatus. Materials and Methods: Patients with primary or secondary hiatal hernia in whom FLF was used to buttress the hiatus repair were included. The FLF was dissected from the anterior abdominal wall, detached from the umbilical area, and transposed below the left lateral liver segment to buttress the cruroplasty. Indocyanine green fluorescence was used to assess vascularization of the flap before and after mobilization. Results: Eighteen consecutive patients underwent laparoscopic FLF cruroplasty reinforcement between October 2019 and January 2021. Indications were primary hiatal hernia (n = 9), recurrent hiatal hernia (n = 4), postsleeve gastrectomy hernia (n = 1), prophylactic hiatal repair during esophagectomy and gastric conduit reconstruction (n = 2), and postesophagectomy hernia (n = 2). All flaps were well vascularized and covered the entire hiatal area. There was no morbidity. At a median follow-up of 8 months (range 3-15), the symptomatic and quality of life scores significantly improved compared with baseline (P < .001), and no anatomic hernia recurrences were detected. Conclusions: FLF is safe for crural buttress and is a viable alternative to mesh in laparoscopic hiatal hernia surgery.

No benefit after neoadjuvant chemoradiation in stage IV rectal cancer: A propensity score-matched analysis on a real-world population.

BACKGROUND: Stage IV rectal cancer occurs in 25% of patients and locoregional control of primary tumor is usually poorly considered, since priority is the treatment of metastatic disease. AIMS: This study evaluates impact of neoadjuvant chemoradiation followed by surgery (nCHRTS) vs. upfront surgery on locoregional control and overall survival in stage IV rectal cancer. METHODS: All patients diagnosed with stage IV rectal carcinoma between 2009 and 2019, undergone elective surgery at the National Cancer Institute of Milan (Italy), were included. Propensity score-based matching was performed between the two study groups. Loco-regional recurrence-free survival (LRRFS) and overall survival (OS) were analysed using Kaplan-Meyer method. RESULTS: A total of 139 patients were analyzed. After propensity score matching, 88 patients were included in the final analysis. The 3-yr LRRFS rates were 80.3% for nCHRTS vs. 90.4% for upfront surgery patients (p = 0.35). The 3-yr OS rates were respectively 81.8% vs. 58% (p = 0.36). KRAS mutation (HR 2.506, p = 0.038) and extra-liver metastases (HR 4.308, p = 0.003) were both predictive of worse OS in univariate analysis. CONCLUSION: The present study failed to demonstrate a significant impact of nCHRTS on LRRFS or OS in stage IV rectal cancer.

Chyle Leak Following Radical En Bloc Esophagectomy with Two-Field Nodal Dissection: Predisposing Factors, Management, and Outcomes.

BACKGROUND: Chyle leak is an uncommon complication following esophagectomy, accounting for significant morbidity and mortality; however, the optimal treatment for the chylothorax is still controversial. OBJECTIVE: The aim of this study was to evaluate the incidence, management, and outcomes of chyle leaks within a specialist esophagogastric cancer center. METHODS: Consecutive patients undergoing esophagectomy for esophageal cancers (adenocarcinoma or squamous cell carcinoma) between 1997 and 2017 at the Northern Oesophagogastric Unit were included from a contemporaneously maintained database. Primary outcome was overall survival, while secondary outcomes were overall complications, anastomotic leaks, and pulmonary complications. RESULTS: During the study period, 992 patients underwent esophagectomy for esophageal cancers, and 5% (n = 50) of them developed chyle leaks. There was no significant difference in survival in patients who developed a chyle leak compared with those who did not (median: 40 vs. 45 months; p = 0.60). Patients developing chyle leaks had a significantly longer length of stay in critical care (median: 4 vs. 2 days; p = 0.002), but no difference in total length of hospital stay. CONCLUSION: Chyle leak remains a complication following esophagectomy, with limited understanding on its pathophysiology in postoperative recovery. However, these data indicate chyle leak does not have a long-term impact on patients and does not affect long-term survival.

Management and complete resection of peritoneal and bone metastases from mucinous rectal carcinoma.

INTRODUCTION: Surgical management of patients with multiple metastases from mucinous rectal carcinoma is feasible. CASE DESCRIPTION: We present a case of a 66-year-old woman with a late onset of peritoneal and coccygeal metastasis from a mucinous rectal carcinoma treated with cytoreductive surgery. After 30 months from rectal resection, the patient underwent exploratory laparotomy with resection of all tumor localizations by means of pelvic peritonectomy, complete supracolic omentectomy, jejuneal resection, appendectomy, and excision of the mobile part of the coccyx. CONCLUSION: This report aims to point out the atypical late-onset recurrence presentation and management of a mucinous carcinoma of the rectum.

The Malnutrition Universal Screening Tool can predict malnutrition in patients with esophageal achalasia.

BACKGROUND: At present, little research has been done to clarify why some achalasia patients do not lose weight or are even obese and to investigate their nutritional status. The aim of this study was to identify predictive factors of malnutrition in these patients and to assess their response to treatment. METHODS: We conducted a retrospective cohort study on consecutive patients referred to a tertiary-care center for laparoscopic or endoscopic treatment of achalasia. Demographics, anthropometric variables, presenting symptoms, and results of the objective investigation were recorded on a prospectively collected database. The severity of symptoms and the nutritional risk were assessed by the Eckardt score and the Malnutrition Universal Screening Tool (MUST), respectively, before and after treatment. RESULTS: Between 2013 and 2019, 171 patients met the study inclusion criteria. There were 87 (50.9%) male and the median age was 53.0 (39-66) years. The median Eckardt score was 6 (interquartile range 3). Based on the MUST score, 121 (70.8%) patients were classified at moderate/high risk of malnutrition. Of these, 93 (76.9%) were overweight or obese. Compared to low-risk group, predictive factors of moderate/high risk of malnutrition were higher Eckardt score [odds ratio (OR) 1.63; 95% CI, 1.35-1.99], more severe dysphagia (OR 2.68, 95% CI, 1.66-4.30), and greater absolute weight loss (OR 2.37; 95% CI, 1.77-3.17). The latter was the only independent predictive factor of malnutrition (OR 2.54; 95% CI, 1.69-3.82). After treatment, the measured MUST score was 0 in 96% of patients. CONCLUSIONS: Over 70% of achalasia patients were at moderate/high risk of malnutrition. These individuals may benefit from a perioperative multidisciplinary approach including dietary intervention to stabilize weight and improve their nutritional status.

Laparoscopic Clipping of the Inferior Mesenteric Artery and Intraoperative Indocyanine Green Angiography for Type II Endoleak Following Endovascular Aneurysm Repair.

Background: Type II endoleaks from a patent inferior mesenteric artery (IMA) occur in up to one-third of patients undergoing endovascular repair of abdominal aortic aneurysms. In the majority of patients, retrograde flow in the aneurysmal sac outside the endograft will seal over time and is rarely associated with sac enlargement or aortic rupture. Intervention is generally recommended in patients with progressively enlarging endoleaks, especially when the sac diameter increases >10 mm during the follow-up, and endovascular IMA embolization has a high rate of treatment failure. Methods: We report a procedure of laparoscopic IMA clipping combined with intraoperative indocyanine green (ICG) angiography to confirm vascular anatomy, colonic perfusion, and the technical success of the procedure. Results: Three selected octogenarian patients with persistent type II endoleak after endovascular repair of abdominal aortic aneurysm underwent IMA clipping with ICG angiography. Mean operative time was 58 ± 9 minutes. There were no procedure-related complications, and no hypersensitivity reactions nor other side effects associated with ICG dye administration occurred. All patients were discharged home on postoperative day 1 and are asymptomatic and free of recurrence at a mean follow-up of 15 months. Conclusions: Laparoscopic IMA clipping is a safe remedial procedure in patients with type II endoleak after endovascular repair of abdominal aortic aneurysms.

Clinical Outcomes of Minimally Invasive Enucleation of Leiomyoma of the Esophagus and Esophagogastric Junction.

OBJECTIVE: Minimally invasive enucleation is the treatment of choice in symptomatic patients with esophageal leiomyoma. Comprehensive long-term follow-up data are lacking. Aim of this study was to review the clinical outcomes of three procedures for enucleation of leiomyoma of the esophagus and esophagogastric junction. METHODS: A single institution retrospective review was performed using a prospectively collected research database and individual medical records. Demographics, presenting symptoms, use of proton-pump inhibitors (PPI), tumor location and size, treatment modalities, and subjective and objective clinical outcomes were recorded. Barium swallow and upper gastrointestinal endoscopy were routinely performed during the follow-up. Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) and Short-Form 36 questionnaires were used to compare quality of life before and after treatment. RESULTS: Between 2002 and 2017, 35 patients underwent minimally invasive leiomyoma enucleation through thoracoscopy (n = 15), laparoscopy (n = 15), and endoscopy (n = 5). The overall morbidity rate was 14.3% and there was no mortality. All patients had a minimum of 1-year follow-up. The median follow-up was 49 (IQR 54) months, and there were no recurrences of leiomyoma. At the latest follow-up, the SF-36 scores were unchanged compared to baseline. However, there was a higher incidence of reflux symptoms (p < 0.050) and PPI use (p < 0.050) after endoscopic treatment. CONCLUSIONS: Minimally invasive enucleation is safe and effective and can be performed by a variety of approaches according to leiomyoma location and morphology. Overall, health-related quality of life outcomes of each procedure appear satisfactory, but PPI dependence was greater in the endoscopic group.

Impact of Laparoscopic Repair of Large Hiatus Hernia on Quality of Life: Observational Cohort Study.

BACKGROUND: Laparoscopic surgery has proven safe and effective in the treatment of large hiatus hernia. Differences may exist between objectively assessed surgical outcomes, symptomatic scores, and patient-reported outcomes. METHODS: An observational, single-arm cohort study was conducted in patients undergoing primary laparoscopic repair with crura mesh augmentation and Toupet fundoplication for large (> 50% of intrathoracic stomach) type III-IV hiatus hernia. Data were extracted from hospital charts and a prospectively updated research database. The main study outcome was quality of life assessed by the Gastroesophageal reflux disease Health-Related Quality of Life (GERD-HRQL) score and the Short-form 36 (SF-36). RESULTS: Between 2013 and 2016, 37 out of 49 operated patients completed the comprehensive quality-of-life evaluation at the 2-year follow-up. The GERD-HRQL score significantly decreased compared to baseline (p < 0.001). All items of the SF-36 significantly improved compared to baseline (p < 0.05). Both Physical and Mental Component Summary scores were significantly higher than preoperative scores, with a medium Cohen's effect size (-0.77 and 0.56, respectively). At the 2-year follow-up, symptoms had disappeared in the majority of patients. The use of proton-pump inhibitors significantly decreased compared to baseline (13.5 vs. 86.4%, p < 0.001). Also, the use of antidepressants and benzodiazepines significantly decreased after surgery (8.1 vs. 32.4%, p < 0.001). The overall alimentary satisfaction score was > 8 in 92% of patients. There were no safety issues related to the use of the absorbable synthetic mesh. The incidence of anatomical hernia recurrence was 5.4%, but no patient with recurrent hernia required surgical revision. CONCLUSIONS: Laparoscopic repair of large hiatus hernia with mesh and partial fundoplication is associated with symptomatic relief, no side-effects, and a significant improvement in disease-specific and generic quality of life at 2-year follow-up.

Impact of Spleen Preserving Laparoscopic Distal Pancreatectomy on Postoperative Infectious Complications: Systematic Review and Meta-Analysis.

BACKGROUND: Laparoscopic distal pancreatectomy with splenectomy is the standard procedure for body and tail pancreatic tumors. Technical difficulties arising from the strict anatomical relationship between pancreas and splenic vessels generally impose a concomitant splenectomy. Previous retrospective studies have shown a reduced risk of postoperative complications and infections in spleen preserved patients, but this is still a debated issue. Aim of this systematic review and meta-analysis was to provide a more robust evidence on the effect of spleen preserving laparoscopic distal pancreatectomy. METHODS: PubMed, MEDLINE, Embase, and Cochrane databases were consulted. Pooled effect measures were calculated using an inverse-variance weighted or Mantel-Haenszel in random effects meta-analysis. Heterogeneity was evaluated using I2-index and Cochran Q-test. RESULTS: Ten observational studies were eligible, and 632 patients were included in the quantitative analysis. Overall, 296 (46.8%) patients underwent laparoscopic distal pancreatectomy with splenectomy (Group S), and 336 (53.2%) patients underwent spleen-preserving laparoscopic distal pancreatectomy (Group SP). In-hospital mortality was 0%. In the group S, the estimated pooled odds ratio of postoperative surgical site infection (SSI) and overall complications was 1.51 (95% confidence interval [CI]: 1.01-2.28; P = .048) and 2.30 (95% CI: 1.11-4.76; P = .024). The estimated pooled odds ratio of pancreatic fistula, postoperative bleeding, and reoperation was 1.64 (P = .094), 1.01 (P = .987), and 1.24 (P = .776), respectively. CONCLUSIONS: Spleen-preserving laparoscopic distal pancreatectomy may reduce postoperative SSI and overall complications. These results should be interpreted with caution but seem meaningful to establish a better evidence-based treatment for distal pancreatic tumors. Further studies are warranted to analyze the role of spleen preserving laparoscopic distal pancreatectomy on long-term outcomes.
