BMC Surg 2024; 24:121. [PMID: 38658891 PMCID: PMC11040831 DOI: 10.1186/s12893-024-02412-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 04/10/2024] [Indexed: 04/26/2024] Open
Abstract
BACKGROUND Nonoperative management of uncomplicated appendicitis is currently being promoted as treatment option, albeit 0.7-2.5% of appendectomies performed due to suspected acute appendicitis show histologically malignant findings. The purpose of this study was to investigate the incidence of neoplasm and malignancy of the appendix in patients presenting with suspected acute appendicitis in real world setting. METHODS This is a retrospective single-centre investigation of 457 patients undergoing appendectomy between the years 2017-2020. The patients' demographics, symptoms and diagnosis, intraoperative findings, and histopathological results were analysed. RESULTS In 3.7% (n = 17) histological analysis revealed neoplasms or malignancies. Median age was 48 years (20-90 years), without sex predominance. Leukocytes (11.3 ± 3.7 G/l) and C-reactive protein (54.2 ± 69.0 mg/l) were elevated. Histological analysis revealed low-grade mucinous appendiceal neoplasia (n = 3), sessile serrated adenoma of the appendix (n = 3), neuroendocrine tumours (n = 7), appendiceal adenocarcinoma of intestinal type (n = 3), and goblet cell carcinoma (n = 1). Additional treatment varied between no treatment or follow-up due to early tumour stage (n = 4), follow-up care (n = 3), additional surgical treatment (n = 8), or best supportive care (n = 2). CONCLUSIONS Preoperative diagnosis of appendiceal tumours is difficult. Nonoperative management of patients with acute, uncomplicated appendicitis potentially prevents the correct diagnosis of malignant appendiceal pathologies. Therefore, close follow-up or surgical removal of the appendix is mandatory.

Abstract
INTRODUCTION Appendectomy has traditionally been considered as a training operation for junior pediatric surgeons during their training period. However, with the increase of laparoscopic appendectomy, there has been a growing concern about the performance of this procedure by junior trainees. Our aim is to analyze intra-/postoperative appendectomy outcomes according to the number of training years during Pediatric Surgical residency training program. METHODS A retrospective study was performed in patients who underwent appendectomy between 2018 and 2021 in our institution, who were divided into 5 groups according to the number of training years of the junior surgeon who performed the intervention (Y1-Y5). Demographics, complicated appendicitis rate, operation time, and postoperative complications were compared. A stratified analysis according to the technique performed (open/laparoscopic) was performed. RESULTS A total of 1274 appendectomized patients were analyzed, of which 1257 (98.7%) were operated on by junior trainees (81 in Y1; 407 in Y2; 337 in Y3; 261 in Y4; and 171 in Y5) without demographic differences between groups. As the year of training increased, an elevation in complicated appendicitis rate was observed, although without statistically significant differences. However, laparoscopic/open appendectomies ratio increased with increasing year of training (p < 0.001). Operative time decreased significantly with increasing year of training (p < 0.001), both in open and laparoscopic appendectomies. There were no significant differences in postoperative complications, nor in the stratified analysis according to surgical technique. CONCLUSION Appendectomy performed by junior pediatric surgery trainees can be considered a safe procedure from the first year of training, regardless of the technique used.

Abstract
OBJECTIVE In a surgical career, teaching of surgical procedures plays a central role. In this study we want to evaluate the influence of teaching in appendectomies on the in-hospital outcome. DESIGN AND SETTING Retrospectively, 26,436 cases from the national quality measurement database (AQC) between the years 2009 and 2017 were evaluated using the diagnosis and the procedure codes. Included were all cases with appendicitis (International Classification of Diseases diagnostic codes K35-K37), surgical treatment (appendectomy), and a documented teaching status of the procedure. Variables were sought in bivariate and multivariate analyses. The occurrence of any complication was the primary outcome, whereas in-hospital mortality was the secondary outcome. PARTICIPANTS A total of 17,106 patients with a mean age of 37 ± 19 years remained for final analysis. A total of 6267 operations (37%), were conducted as teaching-operations. Seventy-four percent of all teaching procedures were performed by residents. RESULTS We found no statistical association between teaching operations and complication rates or mortality. However, the teaching group showed longer duration of surgery (+ 11%). CONCLUSIONS There was no influence of the training status of the appendectomy procedure on complication rates and in-hospital mortality. However, there was a prolonged duration of surgery. Despite these statistically significant differences, a comparable clinical outcome was observed in all patients, thus justifying the benefits of resident training.

World J Emerg Surg 2016; 11:17. [PMID: 27148395 PMCID: PMC4855767 DOI: 10.1186/s13017-016-0074-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2016] [Accepted: 04/29/2016] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND With the spread of the minimally invasive technique, laparoscopic appendectomy (LA) is performed with increasing frequency with excellent results. The method provides surgical residents with an excellent opportunity to learn basic laparoscopic skills and prepares them for more complex interventions. METHODS We evaluated the results of 600 laparoscopic appendectomies performed by 5 surgical residents (Group A) and 5 consultant surgeons (Group B) between 2006 and 2009. Comparing the two groups based on patient demographics, duration of surgery, operation time depending on the severity of inflammation, intraoperative blood loss, conversion rate, hospital stay in days, and postoperative complications. We also assessed the extent to which the minimum of 20 surgeries to be performed in the learning curve period as recommended by the EAES corresponds to our experience. SPPS 20 was used for the statistical analysis. RESULTS Six hundred laparoscopic appendectomies were performed in the study period (Group A: n = 319; Group B: n = 281). A significant difference was found between the two groups in duration of surgery during the learning curve period and when comparing the duration of LA surgeries in the learning curve period with the duration of later surgeries in both groups. The operation time in case of more severe inflammation also showed a significant difference when comparing with simple appendicitis operation time. CONCLUSIONS The rapid introduction of laparoscopy involves few risks, the surgery is also performed with sufficient safety by surgical residents, and it provides them with an excellent opportunity to learn the basic laparoscopy skills.

Abstract
BACKGROUND Appendicular stump closure is a crucial step during laparoscopic appendectomy. Recently, endoclips (ECs) have been described for ligation of the appendicular stump. The objective of this review was to compare outcomes with EC versus endoligature (EL) for appendiceal stump closure during laparoscopic appendectomy. MATERIALS AND METHODS A literature search of Medline, Embase, Cochrane Database, and Google Scholar was performed to identify studies comparing use of EL versus EC in laparoscopic appendectomy between January 1992 and September 2013. Reviews of each study were conducted, and data were extracted. The random-effects model was used to combine data, and between-study heterogeneity was assessed. RESULTS Seven of the 101 identified studies met the inclusion criteria: four randomized controlled trials and three case controlled series. For the primary outcome of perioperative and postoperative complications, there was no significant difference between the EC versus EL groups. No differences were noted in length of hospital stay. However, a significant reduction in operative time was observed with EC as opposed to EL (standardized mean difference=-0.90, 95% confidence interval=-1.26 to -0.54, P=.001). Moreover, EC procedures were less expensive than EL procedures. CONCLUSIONS EC application in the management of appendiceal stump during laparoscopic appendectomy appears to be simple, efficacious, safe, and a cost-effective alternative.

Abstract
BACKGROUND Residents are vital to the clinical workforce of today and tomorrow. Although in training to become specialists, they also provide much of the daily patient care. Residency training aims to prepare residents to provide a high quality of care. It is essential to assess the patient outcome aspects of residency training, to evaluate the effect or impact of global investments made in training programs. Therefore, we conducted a systematic review to evaluate the effects of relevant aspects of residency training on patient outcomes. METHODS The literature was searched from December 2004 to February 2011 using MEDLINE, Cochrane, Embase and the Education Resources Information Center databases with terms related to residency training and (post) graduate medical education and patient outcomes, including mortality, morbidity, complications, length of stay and patient satisfaction. Included studies evaluated the impact of residency training on patient outcomes. RESULTS Ninety-seven articles were included from 182 full-text articles of the initial 2,001 hits. All studies were of average or good quality and the majority had an observational study design. Ninety-six studies provided insight into the effect of 'the level of experience of residents' on patient outcomes during residency training. Within these studies, the start of the academic year was not without risk (five out of 19 studies), but individual progression of residents (seven studies) as well as progression through residency training (nine out of 10 studies) had a positive effect on patient outcomes. Compared with faculty, residents' care resulted mostly in similar patient outcomes when dedicated supervision and additional operation time were arranged for (34 out of 43 studies). After new, modified or improved training programs, patient outcomes remained unchanged or improved (16 out of 17 studies). Only one study focused on physicians' prior training site when assessing the quality of patient care. In this study, training programs were ranked by complication rates of their graduates, thus linking patient outcomes back to where physicians were trained. CONCLUSIONS The majority of studies included in this systematic review drew attention to the fact that patient care appears safe and of equal quality when delivered by residents. A minority of results pointed to some negative patient outcomes from the involvement of residents. Adequate supervision, room for extra operation time, and evaluation of and attention to the individual competence of residents throughout residency training could positively serve patient outcomes. Limited evidence is available on the effect of residency training on later practice. Both qualitative and quantitative research designs are needed to clarify which aspects of residency training best prepare doctors to deliver high quality care.

Abstract
PURPOSE Since laparoscopic procedures have become more common, resident surgeons have to learn complex laparoscopic skills at an early stage of their career. The aim of this study was to compare the short-term clinical outcome parameters of laparoscopic appendectomy (LA) performed by resident surgeons (RS) or attending surgeons (AS). METHODS A total of 1197 LA and 57 open appendectomies were performed in a Swiss community hospital between 1999 and 2009. RS performed 684 operations. Parameters including the duration of the operation and hospital stay, intraoperative complications, surgical reinterventions, and a 30-day morbidity and mortality were observed. RESULTS The mean age of the patients was 35.6 ± 18.17 years. The duration of the operation was longer (61.34 ± 25.73 min [RS] vs. 53.65 ± 29.89 [AS] min; p = 0.0001), but the hospital stay was shorter, in patients treated by RS (3.92 ± 2.61 days [RS] vs. 4.87 ± 3.23 [AS] days; p = 0.0001). The rate of intraoperative complications was not significantly different between the two groups (1.02 % [RS] vs. 0.8 % [AS]; p = 0.6). The need for surgical reintervention (0.6 % [RS] vs. 2.5 % [AS]; p = 0.005) and the 30-day morbidity were higher in patients treated by AS (3.7 % [AS] vs. 1.8 % [RS]; p = 0.04). There was no postoperative mortality. CONCLUSIONS Under appropriate supervision, surgical residents are able to perform LA with results comparable to those of experienced surgeons.

Abstract
AIM Single-incision (or port) laparoscopic surgery (SILS) has recently emerged as a method to improve morbidity and cosmetic benefit of conventional laparoscopic surgery. The literature contains two reports of SILS right hemicolectomy, and we report our experience of this technique. METHOD Seven consecutive, unselected patients underwent SILS retrocaecal appendicectomy, right hemicolectomy, extended right hemicolectomy, colectomy with ileorectal anastomosis, proctocolectomy, anterior resection and restorative proctocolectomy/ileoanal pouch using a single Triport (Olympus Keymed, Southend, UK), conventional instrumentation and nerve block analgesia. Three had undergone previous surgery, two had cancer and two were immunosuppressed. RESULTS Umbilical, right- and left-iliac fossa SILS was feasible using conventional instruments. Operative time ranged between 23 and 195 min (median 48 min). Four patients tolerated normal diet within 6 h (12-16 h for the remainder). Only one patient required postoperative enteral morphine (10 mg × 4). Discharge occurred between 8 and 90 h (median 16 h) of surgery. A secondary haemorrhage from the ileorectal anastomosis was managed conservatively. CONCLUSION SILS colorectal resection is feasible and safe when performed by an experienced laparoscopic surgeon and theatre team. It may have advantages over conventional laparoscopic surgery in terms of reduced pain, lower cost, faster recovery and cosmesis.

Abstract
AIM We analysed the outcome of a consecutive series of 500 unselected patients who underwent elective laparoscopic colorectal resection with anastomosis (ELCRA) under the care of a single surgeon. METHOD A prospectively collected electronic database of all laparoscopic procedures conducted from April 2001 to September 2008 was analysed. RESULTS A total of 500 ELCRAs were performed [230 male and 270 female patients; mean age 65.6 years (range 19-93 years; American Society of Anesthesiologists grade I (103), II (246), III (145) and IV (6)]. Of these, 217 patients underwent high anterior resection. A total of 131 total mesorectal excisions (55 covering ileostomies), 152 right/extended right resections and 240 operations were performed by trainees under supervision. The indications for surgery included cancer (340), diverticular disease (96), Crohn's disease (40) and polyps (24). Mean operating time was 115 min (range 35-550 min). There were eight (1.6%) conversions. The mean length of hospital stay was 5.2 days (median 4 days). A total of 93 (18.6%) patients had an inpatient complication, including ileus (22), wound infection (14), anastomotic leakage (12), enterotomy (2), 'off-screen' enterotomy (2), abscess (3), ureteric injury (1), cardiac arrhythmia (12), myocardial infarction (5), pulmonary embolus (4), pneumonia (1), Clostridium difficile (3) and retention of urine (9). There were 20 (4%) readmissions for complications, including ileus (4), urinary retention (3), abscess formation (2) and leakage (2). The 30-day mortality was nine of 500 (1.8%) following anastomotic leakage (3), duodenal enterotomy (1), bleeding duodenal ulcer (1), C. difficile infection (1) and cardiac complications (3). CONCLUSION This unselected cohort of patients (the largest single surgeon series in the UK) demonstrates that in trained hands low conversion and complication rates can be consistently achieved.

Abstract
AIM The aim of this retrospective cohort study was to compare outcomes in patients who underwent elective laparoscopic colorectal resection with anastomosis performed by a single surgeon or his training fellow. METHOD A prospective electronic database of all laparoscopic procedures between January 2005 and September 2008 was used. Two groups were compared; those patients operated upon by the Consultant trainer (C) and those by seven supervised Fellows (F). Fellows were either post CCT or in their last year of training. Three hundred consecutive patients undergoing laparoscopic colorectal resection with anastomosis were examined, 150 in each group. Groups were matched for indication, age, American Society of Anesthesiology (ASA) grade, cancer T stage and resection performed. Preoperative work-up, operative surgery and anaesthesia were identical between groups. RESULTS No significant difference was demonstrated in age, mean 67 (26-91) or ASA grade. Indications for surgery were; cancer (C) 120, (F) 126, diverticular disease (C) 22, (F) 20, Crohn's disease (C) 8, (F) 7. Fellow's mean operative time was significantly longer at 123 min (95%CI 117-134) compared to the consultant trainer -105 min. (95%CI 98-111): P < 0.01). No significant differences in the complication or conversion rates were demonstrated. Length of stay and the 30-day readmission rates were similar. CONCLUSION In this retrospective cohort study we have demonstrate that when matched patients are compared, supervised trainee operating time is significantly longer than that of the consultant trainer but without any significant increase in length of stay, complication or readmission rates. Training to a level of competency takes time but not at the expense of patient care.

Abstract
BACKGROUND Laparoscopic appendectomy is being performed increasingly, worldwide. To the resident, it provides a valuable opportunity to master basic laparoscopic skills. Studies have shown that laparoscopic appendectomy performed by residents is safe. However, to date, there is no clear evidence for the minimum number of these operations required to achieving proficiency and safety. The aim of this study is to assess the outcome of laparoscopic appendectomies performed by surgical residents and to evaluate the effect of learning curve on patient outcome. METHODS All patients undergoing laparoscopic appendectomies performed by six residents during the study period were reviewed. Data on patient demographics,clinical and histological diagnosis, and outcome variables including operative duration, conversion to open surgery, complications, and length of stay were analyzed. We evaluated the effect of the learning curve by dividing patients into two groups: a first group consisting of the initial 20 patients and a second group consisting of the next 20 patients operated upon independently by each resident. Variables were analyzed to determine any difference between the two groups. RESULTS Three hundred six patients with the clinical diagnosis of acute appendicitis underwent laparoscopic appendectomy by residents. Mean operative time was 83.8 min. Of patients, 14.6% required conversion to open surgery. Mean length of hospitalization was 2.82 days. Operative duration and complication rate were significantly reduced with increasing experience of residents. The length of hospital stay and conversion rate to open surgery remained unchanged. CONCLUSION Operative duration and complications can be reduced with increasing experience of a resident.

Abstract
OBJECTIVE The study set out to analyse the outcomes of an evolving accelerated recovery programme after laparoscopic colorectal resection (LCR). METHOD The results of a prospective electronic database (March 2000 - April 2008) were analysed. RESULTS There were 353 consecutive patients undergoing 'three port' high anterior resection (AR) (237 without covering stoma) and 166 a right hemicolectomy (RHC). One hundred thirty-eight had postoperative analgesia using paracetamol IV and oral analgesia (IVP); 27 (16.3%) received additional parenteral morphine and were excluded. Patient controlled morphine analgesia (PCA) was used in 138. Transversus abdominis plane (TAP) blocks, supplemented by IV paracetamol and oral analgesia were used in the last 50 patients. The time to the resumption of diet was significantly reduced with TAP analgesia (median 12 h) and IVP (median 12 h) compared with PCA median (36 h) (chi(2) = 143; 4df: P < 0.001). The postoperative hospital stay was significantly reduced with TAP analgesia (median 2 days) and IVP (median 3 days) compared with PCA (median 5 days); chi(2) = 73; 2df: P < 0.001. Seventeen (34%) TAP and nine (6.5%) IVP patients were discharged within 24 h of surgery compared with no patient in the PCA group. Ninety-three per cent of PCA, 35% IVP and 10% TAP patients were discharged in more than 3 days. The movement towards 'accelerated recovery' was not associated with any increased risk of urinary retention, return to theatre, readmission and/or 30 day mortality. CONCLUSION Laparoscopic surgery utilizing IV paracetamol and TAP blocks for postoperative analgesia aids safe effective 'accelerated recovery' in an unselected patient population undergoing right hemicolectomy and high anterior resection. Routine epidural anaesthesia is unnecessary for LCR. Morphine PCA is associated with delayed recovery.
