Introduction Studies with inexperienced surgeons in terms of the learning curve for laparoscopic totally extraperitoneal (TEP) inguinal hernia repair are limited. Aim To compare three inexperienced surgeons in terms of the learning curve without supervision. Material and methods Patients’ data, which were from consecutive laparoscopic TEP hernioplasties between December 2017 and February 2020, were analysed retrospectively. The primary outcome was to compare the learning curve of three surgeons (Surgeon A, B, and C) in terms of complications, conversion, and duration of surgery. Secondary outcomes were recurrence rates. Results A total of 299 patients were included in the study. Conversion and intraoperative complication rates decreased after the first 60 cases (from 10% to 2.5%, p = 0.013 and from 9% to 2.5%, p = 0.027, respectively). The mean operative time reached a plateau of less than 40 min after 51–81 cases (Surgeon A 51, B 71, and C 81 cases). Ageing was a risk factor for intraoperative complications and recurrence (p < 0.001, p = 0.008, respectively), and higher body mass index (BMI) was a risk factor for conversion (p = 0.004). Age ≥ 60 years compared to age < 60 years increased intraoperative complications five-fold and recurrence six-fold (p = 0.001). On the other hand, BMI ≥ 30 kg/m 2 increased the possibility of conversion to open surgery nine-fold (p < 0.001). In addition, a positive correlation was found between the operative time and the BMI and VAS score (p = 0.004, p = 0.015, respectively). Conclusions In order to reach the plateau in the operative time during the TEP learning curve period, more than 50 cases should be experienced, whereas more than 60 cases are needed for conversion, intraoperative complications, and recurrence.
Introduction: Studies have shown that sarcopenia is associated with poor outcomes in patients with gastrointestinal cancer undergoing surgery. We aimed to investigate the relationship between postoperative complications of sarcopenic patients who had been operated on for colon cancer and the effects on short-term mortality. Material and methods: In this study, patients who had undergone colon cancer surgery between January 2013 and December 2018 were collected retrospectively. Sarcopenia was diagnosed by the skeletal muscle index (SMI) derived from a preoperative computed tomography scan. Multiple logistic regression analysis was performed to determine whether sarcopenia is associated with postoperative major complications (POMC). Results: The study included 160 patients with a mean age of 62.4 ±12.6 years. Clavien-Dindo grade 1-2 (minor) complications were not significantly different between the groups (p = 0.896). However, grade ≥ 3 (major) complications were detected in 13 (17.8%) patients in the sarcopenic group (SG) and in 5 patients in the non-sarcopenic group (NSG) (5.7%) (p = 0.016). Length of intensive care unit (ICU) stay was longer in SG (p = 0.002) and there was no difference between 1-month and 6-month mortality rates (p = 0.273 and p = 0.402, respectively). According to univariate analyses, sarcopenia and age over 65 years were related to POMC. In multivariate analyses, sarcopenia (odds ratio = 3.039; 95% confidence interval 1.008-9.174; p = 0.048) and advanced age (odds ratio = 3.246; 95% confidence interval 1.078-9.803; p = 0.036) were found to be independent risk factors for POMC. Conclusions: This study showed that while sarcopenia is a risk factor for POMC, sarcopenia also prolongs the duration of ICU stay. Also sarcopenia has no effect on short-term mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
