AbstractBackgroundCytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is routinely used for selected patients with peritoneal metastasis, but can be associated with high complication rates, prolonged hospital stay, and mortality. Our objective was to determine the learning curve of CRS/HIPEC in our institution, representing the largest Asian cohort to date.MethodsA total of 200 consecutive patients with peritoneal metastasis treated with CRS/HIPEC between 2001 and 2016 were grouped into four cohorts of 50 patients and studied. Primary outcomes were severe morbidity (Clavien-Dindo III-V), procedure-related mortality, and duration of ICU and hospital stays. Secondary outcome was duration of surgery.ResultsMedian age was 53 years (10–75). There was no significant age, sex, or histology difference across cohorts. Rates of severe morbidity (23 %), and 60 day inpatient mortality (0.5 %) were comparable to previously reported data. Decreases in rates of serious morbidity, (34 %, 30 %, 12 %, 14 %, p<0.01) and duration of total hospital stay (14, 16, 13, 12 days, p=0.041) were seen across consecutive cohorts. Operation time decreased significantly after the first cohort (10, 7.8, 7.8, 7.2 h, p<0.01), despite increase in average PCI score after the first cohort (8, 14, 12, 13, p=0.063).ConclusionsWhilst 50 cases were adequate for procedural familiarity and decreased average operation time, significant improvement in rate of serious morbidity was observed after 100 operations. We demonstrate a novel biphasic nature to the learning curve, reflecting initial training in which technical competence is achieved, followed by a subsequent period characterized by increasingly complex cases (higher PCI score) and finally refinement of patient selection.

Introduction The implementation of enhanced recovery programmes (ERPs) in colorectal surgery has seen improvements in the length of inpatient stay with no increase in complications. We investigated the role of ERP in radical cystectomy at our institution. Methods Prospective data were collected from 26 consecutive patients prior to the introduction of the ERP and 51 patients who underwent open radical cystectomy within an ERP. Individuals in the ERP cohort did not receive bowel preparation or nasogastric drainage but received preoperative carbohydrate drinks, perioperative epidural analgesia and immediate mobilisation on day 1. Primary outcome measures included duration of intensive care unit (ICU) stay and length of hospital stay. Secondary outcome measures included the time to the passage of flatus and faeces, and time to mobilisation. Other measures that were analysed included operation time and complications. Results Baseline characteristics for both groups were similar. The median length of hospital stay fell from 11.5 days to 10.4 days and the mean ICU stay dropped from 2.4 days to 1.0 days (p=0.01). Time to removal of nasogastric tube, and time to passage of flatus and faeces were significantly shorter in the ERP group, as was the time to full oral diet. Clavien complication rates and 30-day mortality rates were similar in both groups. There were no readmissions. Conclusions ERP in radical cystectomy is safe and not associated with any increase in complications or readmissions. It is associated with reductions in ICU stay, and could also reduce length of hospital stay and duration of postoperative ileus.

Background: In last decade there is a significant change in stroke care especialy with newer data for ischemic stroke treatment there is a movement to obtain comprehensive stroke center certification (CSCC) to provide enhanced complex care for stroke. This study aims to assess the single center quality matrix assessment pre and post CSC status Methods: We reviewed single center cohort of IV tPA (tissue plasminogen activator) in-between year 2010 to 2014 at sparrow health system in mid Michigan region. This cohort was dichotomized in pre CSCC and post CSCC era. Stroke quality matrics data was collected for these patients. Severity of stroke was categorized in mild-moderate vs moderate-severe based on NIH stroke scale (NIHSS) scale. Primary out come for this study was any complication, which is composite end point of in-hospital mortality, and hemorrhage and secondary outcome was hospital stay. Chi square, student’s t test and wilcoxon sum rank test was used to compare both groups. Multivariable regression models were utilized to calculate odd ratios after adjusting with stroke severity. Results: Cohort of IV tPA was identified in-between year 2010 to 2014 (332 hospitalizations off which 241 were pre CSCC and 91 were Post CSCC ). In- hospital complication was lower after receiving CSCC (9.89% vs. 21.99%; p:0.011). In multivariable regression analysis the trend for in hospital complication persisted [Adjusted Odds ratio (OR):0.43–95%confidence-Interval(CI):0.20-0.93–p:0.032] but there was no significant difference in hospital stay (Median days 5 vs. 5; P:673) Conclusion: There is a clear and persistent trend of low in-hospital complication rates after acquiring CSCC quality matrics.

Objectives To compare the advantages and disadvantages between endoscopic and conventional parotid surgeries, and further evaluate the benefits of the new surgical approach - endoscopic parotidectomy. Methods From January 2002 to August 2007 in Changhua Christian Hospital, 33 endoscopic parotid surgeries for selected patients presenting with benign parotid tail disease were compared with one hundred 99 conventional parotid surgeries for the patients with benign parotid tumors by age, gender, wound size, operation time, complication, admission length, and medical cost, retrospectively. Results There is no difference between endoscopic parotid surgeries and conventional parotid surgeries in gender and age. For the wound size, the mean length of the endoscopic parotid surgeries is only 3.1 centimeter and the wounds are almost invisible due to its concealed location behind the ear. Shorter operation time and hospital stay are discovered in the endoscopic parotid surgeries. Less complication rates and medical costs are also found in the endoscopic parotid surgeries. Conclusions Minimally invasive endoscopic parotid surgery provides a safer, less costly, and aesthetic choice for the treatment of benign lesions located in the parotid tail. The advantages of this procedure include smaller operative scar with cosmetic results, shorter operation time and hospital stay, less complication rates and medical costs.

Abstract Background Morbidity and in-hospital mortality rates of patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in Germany are not known. Methods From 2009 to 2018 all patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in Germany were retrospectively analyzed regarding morbidity and in-hospital mortality rates according to nationwide hospital billing data based on diagnosis-related groups (DRG). The “failure to rescue” (FTR) index, characterizing patients who died after severe but potentially manageable complications, was calculated. Results In total, 8463 patients were included and analyzed. Female sex predominated (1.5:1). Colonic origin of peritoneal metastasis was highest throughout all years, reaching its highest level in 2017 (55%; n = 563) and its lowest level in 2012 (40%; n = 349). Median length of hospital stay reached its maximum in 2017 at 23.9 days and its minimum in 2010 at 22.0 days. Analysis of the total FTR index showed a noticeable improvement over the years, reaching its lowest values in 2017 (9.8%) and 2018 (8.8%). The FTR index for sepsis, peritonitis, and pulmonary complications significantly improved over time. Of the 8463 included patients, 290 died during hospital stay, reflecting an in-hospital mortality rate of 3.4%. Conclusion In-hospital mortality after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy is reasonably low compared with other surgical procedures. The improvement in the FTR index reflects efforts to centralize treatment at specialized high-volume centers.

Objectives: To compare perioperative and oncological outcomes between open and laparoscopic radical cystectomy in a single-centre setting. Materials and methods: This study was a retrospective cohort (level 2b evidence) non-randomised review of 228 radical cystectomies that were performed between January 2010 and February 2016. Primary outcome measures were operative time, complications, blood loss and length of hospital stay. Statistical analysis was performed using the SPSS v21.0. Quantitative values were compared with Student’s t-test; categorical variables with the chi-square test. Statistical significance was considered a result of an alpha value less than 0.05. A Kaplan–Meier survival analysis was also conducted. Results: Intraoperative blood loss was lower in laparoscopic surgery (855±673 vs. 716±570 mL, P=0.15), which had a significant impact on transfusion rates ( P=0.02). Operative times were lower in open surgery (339±52.9 vs. 353.1±67.1 minutes, P=0.10), while hospital stay was lower in the laparoscopic group (14.2±11.2 vs. 16.0±13.6 days, P=0.28). Five-year survival rates were superior for patients who underwent an open procedure but were not statistically significant ( P=0.10). Conclusion: This is, so far, the largest cohort to compare laparoscopic and open radical cystectomy. The laparoscopic approach can reduce the need for transfusion; however, there was no statistically significant difference in complication rates, duration of surgery, length of hospital stay or intraoperative blood loss, survival and margin positivity. Level of evidence: Not applicable for this multicentre audit.

Abstract Background Inferior epigastric vascular anatomical landmarks for anterior inguinal hernia repair is an alternative surgical procedure. We present our experience and outcome of the way. Methods We performed a retrospective analysis of 230 patients who received anterior tension-free hernia repair between May 2016 to May 2017. Among these cases, 120 were performed using the traditional transinguinal preperitoneal (TTIPP) technique while 100 were performed using the vascular anatomic landmark transinguinal preperitoneal (VALTIPP) technique. Between these two groups, we compared the operation time, length of hospital stay, complication rates, and the visual analog scale (VAS) for pain at 2 days, 3 months, and 6 months after surgery. Results Surgery was well-tolerated in both groups with no significant hemorrhage or complications. The operation times for the VALTIPP and TTIPP groups were 42.52 ± 9.15 and 53.84 ± 10.64 min (P < 0.05), respectively. Ten patients in the VALTIPP group and 17 patients in the TTIPP group reported sensations of foreign bodies (P < 0.05). The VAS pain score in VALTIPP patients at 2 days (4.0 ± 0.5), 3 months (1.0 ± 0.3), and 6 months (0.9 ± 0.3) were significantly lower when compared with those of TTIPP patients (5.3 ± 0.9 at 2 days, 1.8 ± 0.4 at 3 months, and 1.1 ± 0.1 at 6 months, p < 0.05). No statistically significant differences were found in age, gender, BMI, hernia type and location, follow-up period, incidence of post-operative seromas, recurrence rate, or length of hospital stay. Conclusion Anterior inguinal hernia repair using inferior epigastric vascular anatomical landmarks may lead to reduced operation times, reduced sensations of foreign bodies, and reduced post-operative pain. This technique is simple, practical, and effective in the management of inguinal hernias.

Background We developed a jejunal and colonic experimental human ischemia-reperfusion (IR) model to study pathophysiological intestinal IR mechanisms and potential new intestinal ischemia biomarkers. Our objective was to evaluate the safety of these IR models by comparing patients undergoing surgery with and without in vivo intestinal IR. Methods A retrospective study was performed comparing complication rates and severity, based on the Clavien-Dindo classification system, in patients undergoing pancreatoduodenectomy with (n = 10) and without (n = 20 matched controls) jejunal IR or colorectal surgery with (n = 10) and without (n = 20 matched controls) colon IR. Secondary outcome parameters were operative time, blood loss, 90-day mortality and length of hospital stay. Results Following pancreatic surgery, 63% of the patients experienced one or more postoperative complications. There was no significant difference in incidence or severity of complications between patients undergoing pancreatic surgery with (70%) or without (60%, P = 0.7) jejunal IR. Following colorectal surgery, 60% of the patients experienced one or more postoperative complication. Complication rate and severity were similar in patients with (50%) and without (65%, P = 0.46) colonic IR. Operative time, amount of blood loss, postoperative C-reactive protein, length of hospital stay or mortality were equal in both intervention and control groups for jejunal and colon IR. Conclusion This study showed that human experimental intestinal IR models are safe in patients undergoing pancreatic or colorectal surgery.

BackgroundComputer-assisted jaw reconstruction (CAJR) has benefits in reducing operation time and improving reconstruction accuracy, compared to conventional freehand jaw reconstruction. However, no information is available regarding learning curves in CAJR with the use of 3D-printed patient-specific surgical plates (PSSP). The purpose of this study was to assess surgical outcomes and learning curve for the first 58 consecutive CAJR using 3D-printed PSSP performed by a single surgical team in a single institution.MethodsIn a prospective study, consecutive patients who underwent free flap CAJR using 3D-printed PSSP were included. The determination of proficiency, based on the cumulative sum of surgical success (no major adjustment of 3D-printed PSSP, flap survival) passing the acceptable boundary line of cumulative sum analysis, was the primary outcome. To find out any potential factors influencing the learning curve, baseline characteristics of patients were compared before and after proficiency achievement. Secondary outcomes included inflexion points of the total operation time, blood loss, length of hospital stay, and bone graft deviation, measured by the cumulative sum analysis.ResultsFrom December 2016 to November 2020, 58 consecutive cases underwent surgery performed by a single surgical team. The overall surgical success rate was 94.8% (55/58). A three-stage learning curve of primary outcome was observed. The proficiency was achieved after 23 cases. The proportions of advanced tumor staging and concomitant surgery after obtaining proficiency were significantly higher than those before achieving proficiency (p = 0.046 and p &lt; 0.001, respectively). Mean values of operation time, intraoperative blood loss, length of hospital stay, and bone graft deviation were 532.5 ± 119.2 min, 1,006.8 ± 547.2 ml, 16.1 ± 6.3 days, and 0.9 ± 1.2 mm, respectively. Two trends of learning curve were observed in the CUSUM analyses of total operation time, length of hospital stay, and bone graft deviation, in which the first and second inflexion points occurred between 8 and 17 cases and between 43 and 46 cases, respectively.ConclusionOur results revealed a three-stage learning curve of CAJR with the use of PSSP, including initial learning, plateau, and overlearning. Based on CUSUM analysis, the surgical proficiency was achieved after 23 cases, and total operation time, length of hospital stay, and bone graft deviation stabilized after 8–17 cases.

Abstract Introduction The COVID-19 pandemic provoked a change to normal surgical practice and led to a higher proportion of acute appendicitis (AA) patients being treated conservatively with antibiotics. We aim to analyse patients presenting with AA during the first wave of the pandemic, comparing surgically and conservatively managed patients. Method All patients presenting to our centre with AA between March and July 2020 were included. Six-month follow-up data was collected retrospectively using electronic records. Patients were categorised into surgically and conservatively managed groups. The primary outcome was the complication rate (post-operative complications vs failure of antibiotic treatment) and the secondary outcome was length of hospital stay. Results Fifty-seven patients (n = 57) were admitted with AA, 45.6% (n = 26) managed conservatively compared to 54.4% (n = 31) treated surgically. Higher complication rates were observed amongst the conservatively managed group, although not statistically significant (16% vs 35%; p = 0.131). There was no significant difference in length of hospital stay observed between the two groups (surgical: median, 2; interquartile range, 2-3 vs conservative: median, 3; interquartile range, 2-4). White cell count (WCC) and Alvarado score were higher on admission in the surgical group with statistical significance (p = 0.012 and p = 0.028 respectively). Conclusions Stratification criteria, such as Alvarado score and WCC may identify patients more suitable for conservative management. Longer term follow-up will be carried out, which may alter complication rates in either group. We suggest all patients treated conservatively should undergo computerised tomography (CT) to exclude complicated appendicitis. Further UK-based studies will add to the evidence-base surrounding management of AA during the COVID-19 pandemic.

Introduction: The objective of this study is to compare the outcomes of Desarda repair no mesh and Lichtenstein repair for inguinal hernia. Methods: This is a prospective randomized controlled trial study of 2793 patients having 2936 hernias operated from January 2002 to December 2020.1434 patients were operated using Lichtenstein repair and 1359 using Desarda repair. The variables like age, sex, location, type of hernia, tolerance to local anesthesia, duration of surgery, pain on the first, third and fifth day, hospital stay, complications, re-explorations, morbidity and time to return to normal activities were analyzed. Follow up period was from 1-10 years (median 6.5 years). Results: There were no significant differences regarding age, sex, location, type of hernia, and pain in both the groups. The operation time was 53 minutes in Desarda group and 43 minutes in the Lichtenstein group that is significant (p<0.05).The recurrence was 0.4 % in Desarda group and 0.4 % in Lichtenstein group. But, there were 14 cases of infection to the polypropylene mesh in the Lichtenstein group, 7 of this required re-exploration. The morbidity was also significantly more in Lichtenstein group (5,1 %) as compared to Desarda group (3.1 %). The mean time to return to work in the Desarda group was 8.26 days while a mean of 12.58 days was in the Lichtenstein group. The mean hospital stay was 29 hrs. In Desarda group while it was 49 hours in the Lichtenstein group in those patients who were hospitalized. Conclusions: Desarda repair scores significantly over the Lichtenstein repair in all respects including re-explorations and morbidity. Desarda repair is a better choice as compared with Lichtenstein repair.
