RESUMO

BACKGROUND: In this article we aimed to perform a subgroup analysis using data from the COVID-AGICT study, to investigate the perioperative outcomes of patients undergoing surgery for pancreatic cancers (PC) during the COVID-19 pandemic. METHODS: The primary endpoint of the study was to find out any difference in the tumoral stage of surgically treated PC patients between 2019 and 2020. Surgical and oncological outcomes of the entire cohort of patients were also appraised dividing the entire peri-pandemic period into six three-month timeframes to balance out the comparison between 2019 and 2020. RESULTS: Overall, a total of 1815 patients were surgically treated during 2019 and 2020 in 14 Italian surgical Units. In 2020, the rate of patients treated with an advanced pathological stage was not different compared to 2019 (p = 0.846). During the pandemic, neoadjuvant chemotherapy (NCT) has dropped significantly (6.2% vs 21.4%, p < 0.001) and, for patients who didn't undergo NCT, the latency between diagnosis and surgery was shortened (49.58 ± 37 days vs 77.40 ± 83 days, p < 0.001). During 2020 there was a significant increase in minimally invasive procedures (p < 0.001). The rate of postoperative complication was the same in the two years but during 2020 there was an increase of the medical ones (19% vs 16.1%, p = 0.001). CONCLUSIONS: The post-pandemic dramatic modifications in healthcare provision, in Italy, did not significantly impair the clinical history of PC patients receiving surgical resection. The present study is one of the largest reports available on the argument and may provide the basis for long-term analyses.

RESUMO

INTRODUCTION: Lemmel's syndrome is a rare disease presenting with obstructive jaundice, secondary to common bile duct compression by duodenal diverticulum. PRESENTATION OF CASE: A 79-year-old female was admitted to our emergency department with cholangitis and obstructive jaundice, due to choledocal compression by two periampullary diverticula, with major papilla opening near the biggest one (periampullary diverticulum type III). Endoscopic retrograde cholangiopancreatography didn't succeed sphincterotomy, therefore laparoscopic rendez-vous was performed. DISCUSSION: This case is an example of an unusual cause of obstructive jaundice, which should be mentioned along with choledocolithiasis and biliary or ampullary neoplasms, in order to avoid delay in diagnosis and management. CONCLUSION: The commonest treatment of Lemmel's syndrome reported in literature is ERCP with sphincterotomy, but when endoscopic management fails, interventional radiology and surgery should also be considered.

RESUMO

INTRODUCTION AND IMPORTANCE: Amyand's hernia is a rare type of inguinal hernia which contains vermiform appendix in the inguinal sac, seldom complicated by acute appendicitis. It is usually repaired by open inguinal approach, but laparoscopic technique has been increasingly described in literature; nevertheless, standard of care is far from being defined. Here we report the case of Amyand's hernia complicated by acute appendicitis and simultaneous symptomatic left inguinal hernia, both repaired by laparoscopic technique. CASE PRESENTATION: A 85-years-old man presented with acute appendicitis in Amyand's hernia and simultaneous incarcerated left inguinal hernia. CLINICAL DISCUSSION: After complete preoperative work-up, the patient underwent laparoscopic appendectomy and laparoscopic bilateral hernia repair with mesh. CONCLUSION: Laparoscopic approach may be safe and feasible for Amyand's hernia treatment in emergency setting when performed by expert hands, with minimized risk of surgical site infection (SSI), quick recovery and reduced hospital stay. Laparoscopic hernia repair with mesh can be a reasonable approach in selected cases of bilateral or recurrent hernia, and concomitant intrabdominal inflammation, especially when contamination is scarse and limited to a restricted area.

RESUMO

Introduction: During the last year, the features of peritoneal dialysis patients have changed, and the cases in which there is a need to perform abdominal surgery are growing. Reports of abdominal surgery in patients who are able to continue peritoneal dialysis are increasing. The minimally invasive techniques represent the preferred and safest approach. Such techniques are associated with reduced hospitalization time, less invasiveness, peritoneal integrity preservation, and reduced intra-abdominal inflammation due to regenerative processes. Case Presentation: In this case report, we present a case of major abdominal surgery, in the form of hepatic metastasectomy, performed with the robotic-assisted technique, which allowed catheter and intracorporeal dialysis preservation. The patient showed a strong determination to continue with peritoneal dialysis as long as possible. During the switch to hemodialysis, he performed prophylactic antibiotic therapy to preserve the peritoneal catheter, and the patient was instructed to have a reduced water intake, avoiding excessive ultrafiltration potentially deteriorating the residual renal function. Special care was also taken to avoid any nephrotoxic drug. The peritoneal treatment was restarted after 3 weeks with low volume exchange for the first 10 days, and the pre-surgery dialysis volumes were then re-established. After surgery, the patient showed adequate clearance of solutes and ultrafiltration similar to the preoperative period. The patient did not encounter any wound complications. Conclusion: Robotic surgery represents a further aid in peritoneal dialysis preservation after abdominal surgery. A detailed communication with the patient before performing this kind of procedure and a strong will to preserve the peritoneal method are essential.

RESUMO

BACKGROUND: To date, no standardized protocols nor a quantitative assessment of the near-infrared fluorescence angiography with indocyanine green (NIR-ICG) are available. The aim of this study was to evaluate the timing of fluorescence as a reproducible parameter and its efficacy in predicting anastomotic leakage (AL) in colorectal surgery. METHODS: A consecutive cohort of 108 patients undergoing minimally invasive elective procedures for colorectal cancer was prospectively enrolled. The difference between macro and microperfusion (ΔT) was obtained by calculating the timing of fluorescence at the level of iliac artery division and colonic wall, respectively. RESULTS: Subjects with a ΔT ≥ 15.5± 0.5 s had a higher tendency to develop an AL (p < 0.01). The ΔT/heart rate interaction was found to predict AL with an odds ratio of 1.02 (p < 0.01); a cut-off threshold of 832 was identified (sensitivity 0.86, specificity 0.77). Perfusion parameters were also associated with a faster bowel motility resumption and a reduced length of hospital stay. CONCLUSIONS: The analysis of the timing of fluorescence provides a quantitative, easy evaluation of tissue perfusion. A ΔT/HR interaction ≥832 may be used as a real-time parameter to guide surgical decision making in colorectal surgery.

RESUMO

Acinar cystic transformation (ACT), also known as 'acinar cell cystadenoma', is an uncommon cystic neoplasm of pancreas with unknown malignant potential. This case regards a woman with symptomatic pancreatic head ACT, revealed with pathological exam of specimen after pancreaticoduodenectomy. A 57-years-old patient presented mild hyperbilirubinemia and recurrent cholangitis; she underwent to ERCP, EUS and MRI, and these exams revealed a large cyst of the pancreatic head that caused biliary compression. The discussion of the case by the multidisciplinary group indicated surgical resection. Pancreatic ACT is so rare, and its preoperative diagnosis is difficult. The symptoms of the patients and the features of the cyst are the criteria to choose a surgical resection.

RESUMO

Background: A preliminary analysis from the COVID-Advanced Gastrointestinal Cancer Surgical Treatment (AGICT) study showed that the rate of minimally invasive surgery (MIS) for elective and urgent procedures did not decrease during the pandemic year. In this article, we aimed to perform a subgroup analysis using data from the COVID-AGICT study to evaluate the trend of MIS during the COVID-19 pandemic period in Italy. Methods: This study was conducted collecting data of MIS patients from the COVID-AGICT database. The primary endpoint was to demonstrate whether the SARS-CoV-2 pandemic scenario reduced MIS for elective treatment of gastrointestinal cancer (GIC) in Italy in 2020. The secondary endpoint was to evaluate the impact of the pandemic period on perioperative outcomes in the MIS group. Results: In the pandemic year, 62% of patients underwent surgery with a minimally invasive approach, compared to 63% in 2019 (P = .23). In 2020, the proportion of patients undergoing elective MIS decreased compared to the previous year (80% versus 82%, P = .04), and the rate of urgent MIS did not differ between the 2 years (31% and 33% in 2019 and 2020 - P = .66). Colorectal cancer was less likely to be treated with MIS approach during 2020 (78% versus 75%, P < .001). Conversely, the rate of MIS pancreatic resection was higher in 2020 (28% versus 22%, P < .002). Conversion to an open approach was lower in 2020 (7.2% versus 9.2% - P = .01). Major postoperative complications were similar in both years (11% versus 11%, P = .9). Conclusion: In conclusion, although MIS for elective treatment of GIC in Italy was reduced during the COVID-19 pandemic period, our study revealed that the overall proportion of MIS (elective and urgent) and postoperative outcomes were comparable to the prepandemic period.

RESUMO

Solid pseudopapillary tumour is a rare low-grade malignant potential carcinoma of the pancreas that typically occurs in females in their third decade. It most commonly occurs in the tail of the pancreas, although any site can be affected. Surgical resection is the standard treatment and offers an excellent prognosis. We report a case of a 17-year-old female with an acute onset abdominal pain and a radiological diagnosis of a cystic lesion in the distal pancreas. A robotic-assisted distal pancreatectomy with splenectomy was performed. Robotic-assisted surgery is an emerging technique for the treatment of pancreatic neoplasms. This approach can be considered for younger patients, thanks to the potential advantages of the robotic Da Vinci Xi System.

RESUMO

BACKGROUND: This Italian multicentric retrospective study aimed to investigate the possible changes in outcomes of patients undergoing surgery for gastrointestinal cancers during the COVID-19 pandemic. METHOD: Our primary endpoint was to determine whether the pandemic scenario increased the rate of patients with colorectal, gastroesophageal, and pancreatic cancers resected at an advanced stage in 2020 compared to 2019. Considering different cancer staging systems, we divided tumors into early stages and advanced stages, using pathological outcomes. Furthermore, to assess the impact of the COVID-19 pandemic on surgical outcomes, perioperative data of both 2020 and 2019 were also examined. RESULTS: Overall, a total of 8250 patients, 4370 (53%) and 3880 (47%) were surgically treated during 2019 and 2020 respectively, in 62 Italian surgical Units. In 2020, the rate of patients treated with an advanced pathological stage was not different compared to 2019 (P = 0.25). Nevertheless, the analysis of quarters revealed that in the second half of 2020 the rate of advanced cancer resected, tented to be higher compared with the same months of 2019 (P = 0.05). During the pandemic year 'Charlson Comorbidity Index score of cancer patients (5.38 ± 2.08 vs 5.28 ± 2.22, P = 0.036), neoadjuvant treatments (23.9% vs. 19.5%, P < 0.001), rate of urgent diagnosis (24.2% vs 20.3%, P < 0.001), colorectal cancer urgent resection (9.4% vs. 7.37, P < 0.001), and the rate of positive nodes on the total nodes resected per surgery increased significantly (7 vs 9% - 2.02 ± 4.21 vs 2.39 ± 5.23, P < 0.001). CONCLUSIONS: Although the SARS-CoV-2 pandemic did not influence the pathological stage of colorectal, gastroesophageal, and pancreatic cancers at the time of surgery, our study revealed that the pandemic scenario negatively impacted on several perioperative and post-operative outcomes.

RESUMO

INTRODUCTION AND AIM OF THE STUDY: Dunbar syndrome is a rare disorder due to the external compression of the celiac trunk by the median arcuate ligament. The symptoms include abdominal pain, nausea and vomiting with a significative reduction in patients' quality of life. Laparoscopy has proven to be a safe procedure. The aim of this study is to present a case of Dunbar syndrome undergoing laparoscopic surgery. CASE PRESENTATION: A 40-year-old male patient presented at Emergency Room with upper abdominal pain and dyspepsia, related to food intake. A selective arteriography of the celiac trunk revealed stenosis due to compression of the celiac artery. CLINICAL DISCUSSION: Laparoscopic decompression of the celiac trunk by the median arcuate ligament was performed. Postoperative course was uneventful and the patient was discharged on the 5th postoperative day. CONCLUSION: Minimally invasive surgical division of the arcuate ligament is feasible and safe and it can restore patients' quality of life.

RESUMO

Background: Weight regain after laparoscopic sleeve gastrectomy (LSG) is nowadays a growing concern. Sleeve dilatation and loss of food restriction is considered the main mechanism. The placement of a silicon ring around the gastric tube seems to give benefits in the short term. We report the results of a randomized study comparing LSG and laparoscopic banded sleeve gastrectomy (LBSG) over a 4-year follow-up. Objectives: To evaluate the efficacy of banded sleeve gastrectomy compared to standard sleeve in the midterm. Methods: Between 01/2014 and 01/2015, we randomly assigned 50 patients to receive one of the two procedures. Patients' management was exactly the same, apart from the band placement. We analyzed differences in weight loss, operative time, complication rate, and mortality, with a median follow-up of 4 years. Results: Twenty five patients were assigned to receive LSG (Group A) and 25 LBSG (Group B). The mean preoperative BMI (body mass index) was 47.3 ± 6.58 kg/m2 and 45.95 ± 5.85 kg/m2, respectively. There was no significant difference in the operative time. No intraoperative or postoperative complications occurred. At 12-month follow-up, the mean BMI was 29.72 ± 4.40 kg/m2 in Group A and 27.42 ± 4.47 kg/m2 in Group B (p=0.186). After a median follow-up of 4 years, the mean BMI in Group B was significantly lower than Group A (24.10 ± 4.52 kg/m2 vs 28.80 ± 4.62 kg/m2; p=0.00199). Conclusions: LBSG is a safe procedure, with no impact on postoperative complications. The banded sleeve showed a significant greater weight loss in the midterm follow-up. Considering the issue of weight regain observed after LSG, the placement of a perigastric ring during the first procedure may be a strategy to improve the results. This trial is registered with NCT04228185.

RESUMO

The objective of this study was to evaluate the possibility to undertake an ileocolic resection in complex Crohn's disease using a minimal open abdominal access using standard laparoscopic instruments. The incision was carried out over the previous McBurney scar, with a mean length of 6 cm. Seventy-two patients with complicated Crohn's disease underwent IC resection in the considered period; 12 patients had a McBurney scar due to a previous appendectomy and represented the group of study. Feasibility and safety of the procedure were evaluated. Clinical data and outcome were compared with a control arm of 15 patients who had a standard laparoscopic IC resection, pooled out from our database among those who had a McBurney incision as service incision. Mean operative time and postoperative stay were significantly shorter in the study group. Blood loss and operative costs were also lower in the study group but did not reach statistical significance. Minimal open access ileocolic resection (MOAIR) through a small McBurney incision seems safe and feasible in complex Crohn's disease. Some advantages over standard laparoscopic surgery could be found in surgical outcomes and costs.

RESUMO

Active Crohn's disease has a substantial impact on Quality of Life (QoL). Medical management could be associated to side effects, hospitalization, long treatment period and requires patient's compliance, impacting QoL. Ileocecal resection (ICR) is often required, open or laparoscopic. Aim of the study was to assess Health-Related (HR) QoL changes following ICR, and to identify factors impacting on QoL in the short and mid-term. From a single institution, we created a prospective database of patients undergoing ICR from 01/2009 to 12/2015. HRQoL was analysed with Cleveland Global Quality of Life (CGQL) score, Overall Quality of Happiness (OQH), and asking patients if they would have surgery again. QoL scores were recorded at 30 days, 6, 12 and 36 months postoperatively and compared according to follow-up timing, technique, medical treatment and demographics. Statistical analysis included 187 patients. Mean follow-up was 3.8 ± 2.9 years. Both at 30 days and 6 months postoperatively, CGQL, its items and OQH increased significantly (p < 0.001). Increased values were also recorded at 1 and 3 years; 88% of patients would undergo surgery again. Laparoscopy was associated with improved CGQL scores, while preoperative steroids with worsen data. Young female patients, with penetrating pattern, experienced greater HRQoL improvements. Surgery is associated with improvements of HRQoL and patients' happiness in the short and mid-term. Laparoscopy, steroid-free and young patients showed the best results. ICR should be considered a reasonable alternative to non-operative strategies in selected cases.

RESUMO

Among the bariatric surgery community, it has recently emerged the idea of a possible association between resected gastric volume (RGV) and weight loss after laparoscopic sleeve gastrectomy (LSG). If the size of the sleeve depends on the bougie caliber, the resected volume of the stomach remains something which is not possible to standardize. The aim of the study was to investigate a possible relationship between RGV and weight loss after LSG. We developed a mathematical method to calculate the RGV, based on the specimen size removed during LSG. Ninety-one patients (63 females and 28 males) affected by morbid obesity were included in the study. They underwent LSG between 2014 and 2016. Mean preoperative BMI was 45 ± 6.4. At 1 year after LSG, the mean BMI was 30 ± 5.3 and the EWL% was 65 ± 20.2. The statistical analysis of RGV, BMI, and EWL% at 1-year follow-up did not find any correlation between the volume of stomach removed and the weight loss after LSG. Further studies in the future should clarify the potential role of RGV during LSG. This trial is registered with ClinicalTrials.gov NCT03938025.

RESUMO

Introduction. Aim of the study was trying to draw a final flow chart for the management of gastric leaks after laparoscopic sleeve gastrectomy, based on the review of our cases over 10 years' experience. Material and Methods. We retrospectively reviewed all patients who underwent LSG as a primary operation at the Bariatric Unit of Tor Vergata University Hospital in Rome from 2007 to 2015. Results. Patients included in the study were 418. There were 6 staple line leaks (1.44%). All patients with diagnosis of a leak were initially discharged home in good clinical conditions and then returned to A&E because of the complication. The mean interval between surgery and readmission for leak was 13,4 days (range 6-34 days, SD ± 11.85). We recorded one death (16.67%) due to sepsis. The remaining five cases were successfully treated with a mean healing time of the gastric leak of 55,5 days (range 26-83 days; SD ± 25.44). Conclusion. Choosing the proper treatment depends on clinical stability and on the presence or not of collected abscess. Our treatment protocol showed being associated with low complication rate and minor discomfort to the patients, reducing the need for more invasive procedures.

RESUMO

INTRODUCTION: Obesity is a contributor to the global burden of chronic diseases, including non-alcoholic fatty liver disease and non-alcoholic steatohepatitis (NASH). NASH cirrhosis is becoming a leading indication for liver transplant (LT). Obese transplanted patients have higher morbidity and mortality rates. One strategy, to improve the outcomes in these patients, includes bariatric surgery at the time of LT. Herein we report the first European combined LT and sleeve gastrectomy (SG). CASE PRESENTATION: A 53 years old woman with Hepatocellular carcinoma and Hepatitis C virus related cirrhosis, was referred to our unit. She also presented with severe morbid obesity (BMI 40kg/m2) and insulin-dependent diabetes. Once listed for LT, she was assessed by the bariatric surgery team to undergo a combined LT/SG. At the time of transplantation the patient had a model for end-stage liver disease calculated score of 14 and a BMI of 38kg/m2. The LT was performed using a deceased donor. An experienced bariatric surgeon, following completion of the LT, performed the SG. Operation time was 8h and 50min. The patient had an uneventful recovery and is currently alive, 5 months after the combined procedure, with normal allograft function, significant weight loss (BMI=29kg/m2), and diabetes resolution. CONCLUSION: Despite the ideal approach to the management of the obese LT patients remains unknown, we strongly support the combined procedure during LT in selected patients, offering advantages in terms of allograft and patient survival, maintenance of weigh loss that will ultimately reduce obese related co-morbidities.

RESUMO

Pancreatic ductal adenocarcinoma (PDAC) is characterized by an abundant desmoplastic reaction driven by pancreatic stellate cells (PSCs) that contributes to tumor progression. Here we sought to characterize the interactions between pancreatic cancer cells (PCCs) and PSCs that affect the inflammatory and immune response in pancreatic tumors. Conditioned media from mono- and cocultures of PSCs and PCCs were assayed for expression of cytokines and growth factors. IP-10/CXCL10 was the most highly induced chemokine in coculture of PSCs and PCCs. Its expression was induced in the PSCs by PCCs. IP-10 was elevated in human PDAC specimens, and positively correlated with high stroma content. Furthermore, gene expression of IP-10 and its receptor CXCR3 were significantly associated with the intratumoral presence of regulatory T cells (Tregs). In an independent cohort of 48 patients with resectable pancreatic ductal adenocarcinoma, high IP-10 expression levels correlated with decreased median overall survival. Finally, IP-10 stimulated the ex vivo recruitment of CXCR3+ effector T cells as well as CXCR3+ Tregs derived from patients with PDAC. Our findings suggest that, in pancreatic cancer, CXCR3+ Tregs can be recruited by IP-10 expressed by PSCs in the tumor stroma, leading to immunosuppressive and tumor-promoting effects.

RESUMO

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is an approved primary procedure for morbid obesity, but it is associated with serious complications, such as staple line leaks and bleeding. The objective of this study was to assess the effectiveness of staple line reinforcement (SLR) in reducing leaks and bleeding after LSG. METHODS: A total of 1162 patients underwent LSG (305 males, 857 females). The mean age was 43.7 years and the mean body mass index was 48 kg/m(2). The patients were divided into 6 groups based on the type of SLR, including a no-SLR control group, with evaluation of leaking and bleeding risk and correlation of patients' characteristics with complications. RESULTS: A total of 189 patients underwent LSG without reinforcement. The SLR method was oversewing in 476 patients, bovine pericardium in 312, synthetic polyester in 76, glycolide/trimethylene copolymer in 63, and thrombin matrix in 46. The overall leak frequency was 2.8%; higher with synthetic polyester (7.8%), 4.8% with no reinforcement, and lower with bovine pericardium strips (.3%; P<.01). Postoperative hemorrhage occurred in 35 patients (3%), with a higher frequency being observed without SLR (13.7%; P = .02). Only diabetes was a risk-factor for a leak (P< .01). CONCLUSION: SLR with bovine pericardium strips significantly reduced the leak risk. Postoperative bleeding was significantly lower with all SLR-methods, although there was no significant difference among the various techniques. Patients with type II diabetes had a higher risk of staple line leak after LSG. Further randomized, controlled studies are needed to improve our understanding of the efficacy of SLR during LSG.

RESUMO

BACKGROUND: The principle to avoid surgery for haemorrhoids and/or anal fissure in Crohn's disease (CD) patients is still currently valid despite advances in medical and surgical treatments. In this study we report our prospectively recorded data on medical and surgical treatment of haemorrhoids and anal fissures in CD patients over a period of 8 years. METHODS: Clinical data of patients affected by perianal disease were routinely and prospectively inserted in a database between October 2003 and October 2011 at the Department of Surgery, Tor Vergata University Hospital, Rome. We reviewed and divided in two groups records on CD patients treated either medically or surgically according to the diagnosis of haemorrhoids or anal fissures. Moreover, we compared in each group the outcome in patients with prior diagnosis of CD and in patients diagnosed with CD only after perianal main treatment. RESULTS: Eighty-six CD patients were included in the study; 45 were treated for haemorrhoids and 41 presented with anal fissure. Conservative approach was initially adopted for all patients; in case of medical treatment failure, the presence of stable intestinal disease made them eligible for surgery. Fifteen patients underwent haemorrhoidectomy (open 11; closed 3; stapled 1), and two rubber band ligation. Fourteen patients required surgery for anal fissure (Botox ± fissurectomy 8; LIS 6). In both groups we observed high complication rate, 41.2% for haemorrhoids and 57.1% for anal fissure. Patients who underwent haemorrhoidectomy without certain diagnosis of CD had significantly higher risk of complications. CONCLUSIONS: Conservative treatment of proctologic diseases in CD patients has been advocated given the high risk of complications and the evidence that spontaneous healing may also occur. From these preliminary results a role of surgery is conceivable in high selected patients, but definitve conclusions can't be made. Further randomized trials are needed to establish the efficacy of the surgical approach, giving therapeutic recommendations and guidelines.

RESUMO

INTRODUCTION: Conventional haemorrhoidectomy (CH) is well known to cause significant post-operative pain and delayed return to daily activities. Both surgical wounds and sphincterial apparatus spasms are likely responsible for the pain. In this study, we evaluated the role of glyceryl trinitrate ointment (GTN) in reducing post-operative pain, ameliorating wound healing and recovery after CH. PATIENTS AND METHODS: Between 01/08 and 12/11, 203 patients with symptomatic haemorrhoids were enrolled in the study and received (103 patients) or not (100 patients) 0.4 % GTN ointment for 6 weeks after surgery. Pain was assessed using a 10-cm linear visual analogue scale (VAS). Data on post-operative pain, wound secretion and bleeding, return to normal activities and complications were recorded. Data were analysed using Fisher's exact and Mann-Whitney tests. RESULTS: GTN-treated group experienced significantly less pain during the first week after surgery (p < 0.0001). This difference was more evident starting from post-operative day 4 (p < 0.0001). A significant higher percentage of untreated patients experienced severe pain (mean VAS score > 7) (10 % vs 31 %). There were significant differences in terms of secretion time (p = 0.0052) and bleeding time (p = 0.02) in favor of GTN. In addition, the duration of itching was less in the GTN group (p = 0.0145). Patients treated with GTN were able to an early return to daily activities compared to untreated (p < 0.0001). Fifteen GTN-treated patients (14.6 %) discontinued the application because of local discomfort and headache. CONCLUSIONS: GTN ointment enhances significantly post-operative recovery, reducing pain in terms of duration and intensity. This effect might be secondary to a faster wound healing expressed by reduced secretion, bleeding and itching time.
