RESUMO
INTRODUCTION: Significant numbers of patients undergoing minimally invasive lung surgery develop chronic symptoms such as chronic pain and chronic cough after surgery, which may lead to a reduced quality of life (QoL). Despite this, there remains a dearth of high-quality prospective studies on this topic. Therefore, our study aims to systematically investigate the incidence and progression of long-term chronic symptoms following minimally invasive lung surgery, as well as changes in patient's psychological status and long-term QoL. METHODS: This is a single-centre, observational, prospective study that included patients with stage I non-small cell lung cancer or benign lesions. Prior to surgery, patients' baseline levels of chronic pain, chronic cough and sleep will be documented. Anxiety, depression and QoL assessments will be conducted using the Hospital Anxiety and Depression Scale (HADS) and the European Organisation for Research and Treatment of Cancer (EORTC) 30-item QoL Questionnaire (QLQ-C30). Following surgery, pain and cough will be evaluated during the initial 3 days using the Numeric Pain Rating Scale and Visual Analogue Scale score, with assessments performed thrice daily. Additionally, sleep status will be recorded daily during this period. Subsequently, postoperative chronic symptoms and QoL will be assessed at weeks 1, 2, 4, 12, 26 and 52. Chronic cough will be evaluated using the Leicester Cough Questionnaire, chronic pain will be assessed via the Brief Pain Inventory and McGill Pain Questionnaire while the EORTC QLQ-C30 questionnaire and HADS will provide continuous monitoring of QoL, anxiety and depression statuses. Data will also include the timing of chronic symptom onset, predisposing factors, as well as aggravating and relieving factors. ETHICS AND DISSEMINATION: Ethical approval was obtained from the Ethics Committees of Fujian Medical University Union Hospital. The findings will be disseminated in peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT06016881.

BACKGROUND: PNS is caused by an infection in the sacrococcygeal area triggered by hair particle accumulation in skin tunnels, resulting in infection. Surgical options range from simple excision to complex flap constructions. Primary wound healing failure and recurrence rates contribute to the burden of PNS. RD2 Ver.02, a novel autologous whole-blood clot product, demonstrated safety and efficacy in treating complex cutaneous wounds and was investigated for the management of PNS. METHODS: A Phase II open-label, pilot, single-arm prospective study was conducted from May 2021 to May 2023 (Ethics Committee approval #7952-20). Patients with PNS underwent a minimally invasive trephine procedure under local anesthesia followed by RD2 Ver.02 instillation into the cavity. Primary healing was assessed at 3, 6, and 12 months. Secondary outcomes included the collection of adverse events. RESULTS: Overall, 51 patients participated in the study. At 3 months, 42/51 healed (82.4%), 7/51 (13.7%) were granulating but not completely healed, and 2/51 (3.9%) failed to heal. At 6 and 12 months, 46/51 (90.2%) and 42/51 (82.4%) achieved complete healing, respectively. At 6 months, two PNSs recurred after initial healing and an additional four instances of PNS recurrence observed in 12 months, so a total of recurrence in six patients (11.8%). There were five adverse events (AEs) with no severe adverse events. CONCLUSION: RD2 Ver.02 is a safe and effective treatment of PNS when coupled with a minimally invasive trephine PNS procedure. Further comparative studies are needed to fully assess the role of this novel therapy for PNS.

PURPOSE: Textbook outcome is a comprehensive measure used to assess surgical quality and is increasingly being recognized as a valuable evaluation tool. Delta-shaped anastomosis (DA), an intracorporeal gastroduodenostomy, is a viable option for minimally invasive distal gastrectomy in patients with gastric cancer. This study aims to evaluate the surgical outcomes and calculate the textbook outcome of DA. MATERIALS AND METHODS: In this retrospective study, the records of 4,902 patients who underwent minimally invasive distal gastrectomy for DA between 2009 and 2020 were reviewed. The data were categorized into three phases to analyze the trends over time. Surgical outcomes, including the operation time, length of post-operative hospital stay, and complication rates, were assessed, and the textbook outcome was calculated. RESULTS: Among 4,505 patients, the textbook outcome is achieved in 3,736 (82.9%). Post-operative complications affect the textbook outcome the most significantly (91.9%). The highest textbook outcome is achieved in phase 2 (85.0%), which surpasses the rates of in phase 1 (81.7%) and phase 3 (82.3%). The post-operative complication rate within 30 d after surgery is 8.7%, and the rate of major complications exceeding the Clavien-Dindo classification grade 3 is 2.4%. CONCLUSIONS: Based on the outcomes of a large dataset, DA can be considered safe and feasible for gastric cancer.

BACKGROUND/AIM: Although minimally invasive distal pancreatectomy (MIDP) has become a treatment option for benign and malignant pancreatic tumors, the safety and efficacy of reinforced staplers in MIDP remain controversial. The present study was performed to evaluate the safety of reinforced staplers in MIDP and identify the risk factors for postoperative pancreatic fistula (POPF) after MIDP with reinforced staplers. PATIENTS AND METHODS: In total, 92 consecutive patients who underwent MIDP at NHO Kyushu Medical Center from July 2016 to August 2023 were enrolled in this retrospective study. In all patients, a reinforced black cartridge triple-row stapler (Covidien Japan, Tokyo, Japan) was used during MIDP. The primary endpoint was the incidence of clinically relevant POPF. The risk factors for POPF were evaluated using multivariate analysis. RESULTS: Among the 92 patients, 74 underwent laparoscopic distal pancreatectomy and 18 underwent robot-assisted distal pancreatectomy. Clinically relevant POPF occurred in seven (7.6%) of 92 patients. The rate of severe complications (Clavien-Dindo grade ≥III) was 10.8%, and the mortality rate was 0%. The median postoperative hospital stay was 14 days. Multivariate logistic regression analysis showed that the independent risk factor for clinically relevant POPF after MIDP with a reinforced stapler was a body mass index of ≥22.6 kg/m2 (p=0.050, odds ratio=7.60). CONCLUSION: This study confirmed the safety and efficacy of reinforced staplers for preventing POPF after MIDP. A high body mass index was the only risk factor for clinically relevant POPF after MIDP with a reinforced stapler.

PURPOSE: Despite the increasing preference for minimally invasive surgery for colorectal cancer (CRC), the incidence of prolonged postoperative ileus (PPOI) remains high. Thus, this study aimed to identify risk factors for PPOI in patients with CRC who underwent minimally invasive surgery (MICRS) and to develop a practical nomogram for predicting individual PPOI risk. METHODS: A consecutive series of 2368 patients who underwent MICRS between 2013 and 2023 at two tertiary academic centers were retrospectively studied. Using the data from 1895 patients in the training cohort, a multivariable logistic regression model was employed to select significant variables for the construction of a best-fit nomogram. The nomogram was internally and externally validated. RESULTS: PPOI occurred in 9.5% of patients. Six independent risk factors were identified to construct a nomogram: advanced age (OR 1.055, P = 0.002), male sex (OR 2.914, P = 0.011), age-adjusted Charlson comorbidity index ≥ 6 (OR 2.643, P = 0.025), preoperative sarcopenia (OR 0.857, P = 0.02), preoperative prognostic nutritional index (OR 2.206, P = 0.047), and intraoperative fluid overload (OR 2.227, P = 0.045). The AUCs of the model for predicting PPOI in the training and external validation cohorts were 0.887 and 0.838, respectively. The calibration curves demonstrated excellent consistency between the nomogram-predicted and observed probabilities in both cohorts. Individuals with a total nomogram score of < 197 or ≥ 197 were considered to be at low or high risk for PPOI, respectively. CONCLUSIONS: The integrated nomogram we developed could provide personalized risk prediction of PPOI after MICRS. This quantification enables surgeons to implement personalized prevention strategies, thereby improving patient outcomes.

BACKGROUND: This study aimed to clarify the efficacy and safety of minimally invasive transabdominal surgery (MIS) with transperineal minimal invasive surgery (tpMIS) for sacrectomy in advanced primary and recurrent pelvic malignancies. METHODS: Using a prospectively collected database, we retrospectively analyzed the clinical, surgical, and pathological outcomes of MIS with tpMIS for sacrectomies. Surgery was performed between February 2019 and May 2023. The median follow-up period was 27 months (5-46 months). RESULTS: Fifteen consecutive patients were included in this analysis. The diagnoses were as follows: recurrent rectal cancer, n = 11 (73%); primary rectal cancer, n = 3 (20%); and recurrent ovarian cancer, n = 1 (7%). Seven patients (47%) underwent pelvic exenteration with sacrectomy, six patients (40%) underwent abdominoperineal resection (APR) with sacrectomy, and two patients (13%) underwent tumor resection with sacrectomy. The median intraoperative blood loss was 235 ml (range 45-1320 ml). The postoperative complications (Clavien-Dindo grade ≥ 3a) were graded as follows: 3a, n = 6 (40%); 3b, n = 1 (7%); and ≥ 4, n = 0 (0%). Pathological examinations demonstrated that R0 was achieved in 13 patients (87%). During the follow-up period, two patients (13%) developed local re-recurrence due to recurrent cancer. The remaining 13 patients (87%) had no local disease. Fourteen patients (93%) survived. CONCLUSIONS: Although the patient cohort in this study is heterogeneous, MIS with tpMIS was associated with a very small amount of blood loss, a low incidence of severe postoperative complications, and an acceptable R0 resection rate. Further studies are needed to clarify the long-term oncological feasibility.

PURPOSE: Achilles tendon ruptures (ATRs) close to the insertion, in high-level athletes, and in patients at high risk of re-rupture, may be better suited to operative repair. Minimally Invasive Repair (MIR) of the Achilles tendon has excellent outcome and low complication rates. Traditionally MIR has showed lower repair strength, failing due to suture pull-out from the distal tendon stump. The aim of this study was to describe the outcome of ATR patients who received transosseous distal suture placement using a standard technique as a reference. METHODS: Following ATR, patients were evaluated for pre-injury activity level, body weight, location of the tear and size of the distal Achilles tendon stump. Patients considered to be at high-risk of re-rupture: Tegner level ≥ 8, body weight ≥ 105Kg and distal ATR, received transosseous (TO) distal suture placement (n = 20) rather than the usual transtendinous (TT) technique (n = 55). Patient reported outcome measures and functional evaluation was performed at 12 months following repair. RESULTS: At 12 months follow up both methods resulted in good median (IQR) Achilles tendon Total Rupture Score TO 83.8 (74-88.3) vs. TT 90 (79-94), low increased relative Achilles Tendon Resting Angle TO -3.5Ë (3.6) vs. TT -3.5Ë (3.3) and mean (SD) Single leg Heel-Rise Height Index TO 88.2% (9.9) vs. TT 85.6% (9.9) (n.s.). There were 4 re-ruptures in the high-risk group and 2 in the group receiving TT distal suture placement. All but one of these were traumatic in nature. The mode of failure following TO distal suture placement was proximal suture pull out. CONCLUSIONS: To distal suture placement during minimally-invasive Achilles tendon repair for higher-risk patients can lead to results equivalent to those in lower-risk patients treated with a standard TT MIR technique, except for the re-rupture rate which remained higher. There may be factors that have greater influence on outcome other than suture placement following ATR.

BACKGROUND: Current strategies for hypertrophic scar prevention and treatment are limited. OBJECTIVE: To facilitate these efforts, a minimally invasive hypertrophic scar model was created in a rabbit ear for the first time based on previous methods used to induce ischemia. METHODS: Six New Zealand white rabbits (12 ears total) were studied. First, ischemia was achieved by ligating the cranial artery, cranial vein and central artery, while preserving the caudal artery, caudal vein and central vein, respectively. The relative level of ischemia induced at time of surgery, both baseline and maximum perfusion, was assessed with a fluorescent light-assisted angiography and demonstrated lower rates of perfusion in the ischemic ears. Following vascular injury, a 2-cm full thickness linear wound was created on the ventral ear and closed with 4 - 0 Nylon sutures under high tension. For each rabbit, one ear received a combination of ischemia and wounding with suture tension (n = 6), while the other ear was non-ischemic with wounding and suture tension alone (n = 6). RESULTS: Four weeks post-operatively, ischemic ears developed scar hypertrophy (histological scar thickness: 1.1 ± 0.2 mm versus 0.5 ± 0.1 mm, p < 0.05). CONCLUSION: Herein, we describe a novel, prototypical minimally invasive rabbit ear model of hypertrophic scar formation that can allow investigation of new drugs for scar prevention.

Background and Objectives: Proximal junctional kyphosis (PJK) and failure (PJF), the most prevalent complications following long-segment thoracolumbar fusions for adult spinal deformity (ASD), remain lacking in defined preventive measures. We studied whether one of the previously reported strategies with successful results-a prophylactic augmentation of the uppermost instrumented vertebra (UIV) and supra-adjacent vertebra to the UIV (UIV + 1) with polymethylmethacrylate (PMMA)-could also serve as a preventive measure of PJK/PJF in minimally invasive surgery (MIS). Materials and Methods: The study included 29 ASD patients who underwent a combination of minimally invasive lateral lumbar interbody fusion (MIS-LLIF) at L1-2 through L4-5, all-pedicle-screw instrumentation from the lower thoracic spine to the sacrum, S2-alar-iliac fixation, and two-level balloon-assisted PMMA vertebroplasty at the UIV and UIV + 1. Results: With a minimum 3-year follow-up, non-PJK/PJF group accounted for fifteen patients (52%), PJK for eight patients (28%), and PJF requiring surgical revision for six patients (21%). We had a total of seven patients with proximal junctional fracture, even though no patients showed implant/bone interface failure with screw pullout, probably through the effect of PMMA. In contrast to the PJK cohort, six PJF patients all had varying degrees of neurologic deficits from modified Frankel grade C to D3, which recovered to grades D3 and to grade D2 in three patients each, after a revision operation of proximal extension of instrumented fusion with or without neural decompression. None of the possible demographic and radiologic risk factors showed statistical differences between the non-PJK/PJF, PJK, and PJF groups. Conclusions: Compared with the traditional open surgical approach used in the previous studies with a positive result for the prophylactic two-level cement augmentation, the MIS procedures with substantial benefits to patients in terms of less access-related morbidity and less blood loss also provide a greater segmental stability, which, however, may have a negative effect on the development of PJK/PJF.

OBJECTIVES: Minimally invasive surgery for treatment of gynecologic malignancies is associated with decreased pain, fewer complications, earlier return to activity, lower cost, and shorter hospital stays. Patients are often discharged the day of surgery, but occasionally stay overnight due to prolonged post-anesthesia care unit (PACU) stays. The objective of this study was to identify risk factors for prolonged PACU length of stay (LOS). METHODS: This is a single institution retrospective review of patients who underwent minimally invasive hysterectomy for gynecologic cancer from 2019 to 2022 and had a hospital stay <24-h. The primary outcome was PACU LOS. Demographics, pre-operative diagnoses, and surgical characteristics were recorded. After Box-Cox transformation, linear regression was used to determine significant predictors of PACU LOS. RESULTS: For the 661 patients identified, median PACU LOS was 5.04 h (range 2.16-23.76 h). On univariate analysis, longer PACU LOS was associated with increased age (ρ = 0.106, p = 0.006), non-partnered status [mean difference (MD) = 0.019, p = 0.099], increased alcohol use (MD = 0.018, p = 0.102), increased Charlson Comorbidity Index (CCI) score (ρ = 0.065, p = 0.097), and ASA class ≥3 (MD = 0.033, p = 0.002). Using multivariate linear regression, increased age (R2 = 0.0011, p = 0.043), non-partnered status (R2 = 0.0389, p < 0.001), and ASA class ≥3 (R2 = 0.0250, p = 0.023) were associated with increased PACU LOS. CONCLUSIONS: Identifying patients at risk for prolonged PACU LOS, including patients who are older, non-partnered, and have an ASA class ≥3, may allow for interventions to improve patient experience, better utilize hospital resources, decrease PACU overcrowding, and limit postoperative admissions and complications. The relationship between non-partnered status and PACU LOS is the most novel relationship identified in this study.

BACKGROUND: Concerns regarding high open surgery-related maternal morbidity have led to improvements in minimally invasive fetal surgeries. OBJECTIVE: To analyze the perinatal and maternal outcomes of minimally invasive fetal surgery performed in Rio de Janeiro, Brazil. DESIGN AND SETTING: Retrospective cohort study conducted in two tertiary reference centers. METHODS: This retrospective descriptive study was conducted using medical records from 2011 to 2019. The outcomes included maternal and pregnancy complications, neonatal morbidity, and mortality from the intrauterine period to hospital discharge. RESULTS: Fifty mothers and 70 fetuses were included in this study. The pathologies included twin-twin transfusion syndrome, congenital diaphragmatic hernia, myelomeningocele, lower urinary tract obstruction, pleural effusion, congenital upper airway obstruction syndrome, and amniotic band syndrome. Regarding maternal complications, 8% had anesthetic complications, 12% had infectious complications, and 6% required blood transfusions. The mean gestational age at surgery was 25 weeks, the mean gestational age at delivery was 33 weeks, 83% of fetuses undergoing surgery were born alive, and 69% were discharged from the neonatal intensive care unit. CONCLUSION: Despite the small sample size, we demonstrated that minimally invasive fetal surgeries are safe for pregnant women. Perinatal mortality and prematurity rates in this study were comparable to those previously. Prematurity remains the most significant problem associated with fetal surgery.

Lumbar canal stenosis (LCS) is a common spinal disease affecting the elderly. Primarily it is asymptomatic until there is neurogenic claudication. Minimally invasive surgical (MIS) techniques are used to treat patients with lumbar spinal stenosis (LSS), while tubular system with alternative multilevel decompression is specifically used for those with minimal back pain and no mechanical instability on dynamic imaging. The aim of the study is to evaluate surgical outcome of Slalom procedure and complications in Middle East population. One hundred and five patients with lumbar stenosis (61 males and 44 females) underwent the procedure between 2015-2021 who were regularly followed-up using preoperative and postoperative COMI score (the core outcome measure index) at six months after index surgery. Progressive improvement in COMI score from average seven pre-op score to an average of three after six months of index surgery. The postoperative complications were dural tear (6.67%), Postoperative infection (3.81%), mechanical instability (1.9%), postoperative neuritis (8.57%) and death (1.9%).

BACKGROUND: Despite the increased use of minimally invasive approaches for pancreatoduodenectomy (PD), the association between surgical approach and venous thromboembolism (VTE) risk is still unknown. This study aims to compare VTE rates following open (OPD) and minimally invasive pancreatoduodenectomy (MIPD). METHOD: MEDLINE, Web of Sciences and EMBASE databases were searched to identify eligible studies. Studies were considered suitable if the incidence of postoperative VTE in open and minimally invasive (laparoscopic or robotic) pancreatic surgery was reported. The review was conducted following the PRISMA guidelines. RESULTS: Five studies including 12 984 patients met the inclusion criteria and were considered for meta-analysis. A total of 11 060 patients underwent OPD and 1924 MIPD. Overall, patients who underwent OPD had a lower rate of VTE compared to MIPD (3.6 % vs 4.6 %, OR (95 % CI) = 0.66 (0.52-0.85), p < 0.001). Subgroup analysis showed similar results for pulmonary embolism (PE) (1.1 % in OPD vs 1.9 % in MIPD, OR (95 % CI) = 0.54 (0.36-0.80), p 0.002) and deep venous thrombosis (DVT) (1.3 % in OPD vs 3.1 % in MIPD, OR (95 % CI) = 0.48 (0.29-0.79), p 0.004). CONCLUSION: Patients who undergo minimally invasive pancreatoduodenectomy have a higher incidence of postoperative VTE when compared to open pancreatoduodenectomy.

BACKGROUND: A well-known complication of laparoscopic management of gynaecologic masses and cancers is the need to perform an intraoperative conversion to laparotomy. The purpose of this study was to identify novel patient risk factors for conversion from minimally invasive to open surgeries for gynaecologic oncology operations. METHODS: This was a retrospective cohort study of 1356 patients ≥18 years of age who underwent surgeries for gynaecologic masses or malignancies between February 2015 and May 2020 at a single academic medical centre. Multivariable logistic regression was used to study the effects of older age, higher body mass index (BMI), higher American Society of Anaesthesiologist (ASA) physical status, and lower preoperative haemoglobin (Hb) on odds of converting from minimally invasive to open surgery. Receiver operating characteristic (ROC) curve analysis assessed the discriminatory ability of a risk prediction model for conversion. RESULTS: A total of 704 planned minimally invasive surgeries were included with an overall conversion rate of 6.1% (43/704). Preoperative Hb was lowest for conversion cases, compared to minimally invasive and open cases (11.6 ± 1.9 vs 12.8 ± 1.5 vs 11.8 ± 1.9 g/dL, p<.001). Patients with preoperative Hb <10 g/dL had an adjusted odds ratio (OR) of 3.94 (CI: 1.65-9.41, p=.002) for conversion while patients with BMI ≥30 kg/m2 had an adjusted OR of 2.86 (CI: 1.50-5.46, p=.001) for conversion. ROC curve analysis using predictive variables of age >50 years, BMI ≥30 kg/m2, ASA physical status >2, and preoperative haemoglobin <10 g/dL resulted in an area under the ROC curve of 0.71. Patients with 2 or more risk factors were at highest risk of requiring an intraoperative conversion (12.0%). CONCLUSIONS: Lower preoperative haemoglobin is a novel risk factor for conversion from minimally invasive to open gynaecologic oncology surgeries and stratifying patients based on conversion risk may be helpful for preoperative planning.
Minimally invasive surgery for management of gynaecologic masses (masses that affect the female reproductive organs) is often preferred over more invasive surgery, because it involves smaller surgical incisions and can have overall better recovery time. However, one unwanted complication of minimally invasive surgery is the need to unexpectedly convert the surgery to an open surgery, which entails a larger incision and is a higher risk procedure. In our study, we aimed to find patient characteristics that are associated with higher risk of converting a minimally invasive surgery to an open surgery. Our study identified that lower levels of preoperative haemoglobin, the protein that carries oxygen within red blood cells, is correlated with higher risk for conversion. This new risk factor was used with other known risk factors, including having higher age, higher body mass index, and higher baseline medical complexity to create a model to help surgical teams identify high risk patients for conversion. This model may be useful for surgical planning before and during the operation to improve patient outcomes.

OBJECTIVE: To study the possibilities of minimally invasive methods for removing intra-abdominal calculi after laparoscopic cholecystectomy. MATERIAL AND METHODS: There were 5 patients with abdominal abscesses associated with infected calculi after previous laparoscopic cholecystectomy at the Sklifosovsky Research Institute for Emergency Care between 2020 and 2023. Mean age of patients was 55±12 years. There were 3 (60%) women and 2 (40%) men. All patients underwent minimally invasive treatment. RESULTS: Four patients (80%) underwent percutaneous drainage of abscess with subsequent replacement by larger drains and removal of calculi with endoscopic assistance. Event-free period after cholecystectomy was 44±32 months. One patient developed subhepatic abscess in 72 months after laparoscopic cholecystectomy. This patient underwent transluminal removal of calculus through the duodenal wall. There was 1 calculus in 3 (60%) patients, 2 calculi in 1 (20%) patient and 3 calculi in 1 (20%) patient. CONCLUSION: The above-mentioned cases demonstrate successful minimally invasive interventions for symptomatic abdominal calculi after laparoscopic cholecystectomy. Minimally invasive treatment can reduce surgical aggression and accelerate rehabilitation.

BACKGROUND: Central pancreatectomy is a surgical procedure for benign and low-grade malignant tumors which located in the neck and proximal body of the pancreas that facilitates the preservation of pancreatic endocrine and exocrine functions but has a high morbidity rate, especially postoperative pancreatic fistula (POPF). The aim of this systematic review and meta-analysis was to evaluate the safety and effectiveness between minimally invasive central pancreatectomy (MICP) and open central pancreatectomy (OCP) basing on perioperative outcomes. METHODS: An extensive literature search to compare MICP and OCP was conducted from October 2003 to October 2023 on PubMed, Medline, Embase, Web of Science, and the Cochrane Library. Fixed-effect models or random effects were selected based on heterogeneity, and pooled odds ratios (ORs) or mean differences (MDs) with 95% confidence intervals (CIs) were calculated. RESULTS: A total of 10 studies with a total of 510 patients were included. There was no significant difference in POPF between MICP and OCP (OR = 0.95; 95% CI [0.64, 1.43]; P = 0.82), whereas intraoperative blood loss (MD = - 125.13; 95% CI [- 194.77, -55.49]; P < 0.001) and length of hospital stay (MD = - 2.86; 95% CI [- 5.00, - 0.72]; P = 0.009) were in favor of MICP compared to OCP, and there was a strong trend toward a lower intraoperative transfusion rate in MICP than in OCP (MD = 0.34; 95% CI [0.11, 1.00]; P = 0.05). There was no significant difference in other outcomes between the two groups. CONCLUSION: MICP was as safe and effective as OCP and had less intraoperative blood loss and a shorter length of hospital stay. However, further studies are needed to confirm the results.

A male patient in his early 30s underwent minimally invasive repair of pectus excavatum. According to standard Nuss bar procedure, a 30-degree thoracoscope was introduced through a right midaxillary 10 mm trocar in the 4th intercostal space. Two bars and five stabilisers were placed in a retromuscular position. After discharge, the patient experienced right upper back pain requiring prolonged opioid usage for three months and right scapular winging limiting functional activities. After conservative treatment with physiotherapy for 11 months, the patient still suffered from residual scapula alata with pain and muscle weakness. On suspicion of long thoracic nerve neuropraxia related to the thoracoscope placement, an electromyogram was conducted 16 months following surgery, revealing mild polyphasic potentials of the serratus anterior muscle without abnormal muscle unit action potential. After extended conservative therapy for another year, physical examination 28 months after surgery showed almost complete resolution of scapular winging.

INTRODUCTION: It is not yet clear whether cardiac surgery by mini-incision (minimally invasive cardiac surgery [MICS]) is overall less painful than the conventional approach by full sternotomy (FS). A meta-analysis is necessary to investigate polled results on this topic. METHODS: PubMed®/MEDLINE, Cochrane CENTRAL, Latin American and Caribbean Health Sciences Literature (or LILACS), and Scientific Electronic Library Online (or SciELO) were searched for all clinical trials, reported until 2022, comparing FS with MICS in coronary artery bypass grafting (CABG), mitral valve surgery (MVS), and aortic valve replacement (AVR), and postoperative pain outcome was analyzed. Main summary measures were the method of standardized mean differences (SMD) with a 95% confidence interval (CI) and P-values (considered statistically significant when < 0.05). RESULTS: In AVR, the general estimate of postoperative pain effect favored MICS (SMD 0.87 [95% CI 0.04 to 1.71], P=0.04). However, in the sensitivity analysis, there was no difference between the groups (SMD 0.70 [95% CI -0.69 to 2.09], P=0.32). For MVS, it was not possible to perform a meta-analysis with the included studies, because they had different methodologies. In CABG, the general estimate of the effect of postoperative pain did not favor any of the approaches (SMD -0.40 [95% CI -1.07 to 0.26], P=0.23), which was confirmed by sensitivity analysis (SMD -0.02 [95% CI -0.71 to 0.67], P=0.95). CONCLUSION: MICS was not globally less painful than the FS approach. It seems that postoperative pain is more related to the degree of tissue retraction than to the size of the incision.

OBJECTIVE: The aim of this study was to compare the incidence of intra-operative and post-operative complications in open and minimally invasive radical hysterectomy for patients with early-stage cervical cancer. METHODS: Data were collected from the SUCCOR database of 1272 patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO), 2009) who underwent radical hysterectomy in Europe between January 2013 and December 2014. We reviewed the duration of the surgeries, estimated blood loss, length of hospital stay, intra-operative and post-operative complications. The inclusion criteria were age ≥18 years and histologic type (squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma). Pelvic MRI confirming a tumor diameter ≤4 cm with no parametrial invasion and a pre-operative CT scan, MRI, or positron emission tomography CT demonstrating no extra-cervical metastatic disease were mandatory. Outcomes of interest were any grade >3 adverse events, intra-operative adverse events, post-operative adverse events, length of hospital stay, length of operation, and blood loss. RESULTS: The study included 1156 patients, 633 (54%) in the open surgery group and 523 (46%) in the minimally invasive surgery group. Median age was 46 years (range 18-82), median body mass index 25 kg/m2 (range 15-68), and 1022 (88.3%) patients were considered to have an optimal performance status (ECOG Performance Status 0). The most common histologic tumor type was squamous carcinoma (n=794, 68.7%) and the most frequent FIGO staging was IB1 (n=510, 44.1%). In the minimally invasive surgery group the median duration of surgery was longer (240 vs 187 min, p<0.01), median estimated blood loss was lower (100 vs 300 mL, p<0.01), and median length of hospital stay was shorter (4 vs 7 days, p<0.01) compared with the abdominal surgery group. There was no difference in the overall incidence of intra-operative and post-operative complications between the two groups. Regarding grade I complications, the incidence of vaginal bleeding (2.9% vs 0.6%, p<0.01) and vaginal cuff dehiscence was higher in the minimally invasive surgery group than in the open group (3.3% vs 0.5%, p<0.01). Regarding grade III post-operative complications, bladder dysfunction (1.3% vs 0.2%, p=0.046) and abdominal wall infection (1.1% vs 0%, p=0.018) were more common in the open surgery group than in the minimally invasive surgery group. Ureteral fistula was more frequent in the minimally invasive group than in the open surgery group (1.7% vs 0.5%, p=0.037). CONCLUSION: Our study showed that there was no significant difference in the overall incidence of intra-operative and post-operative complications between minimally invasive radical hysterectomy and the open approach.

BACKGROUND: This study was a secondary analysis of the ROBOGYN-1004 trial conducted between 2010 and 2015. The study aimed to identify factors that affect postoperative morbidity after either robot-assisted laparoscopy (RL) or conventional laparoscopy (CL) in gynecologic oncology. METHODS: The study used two-level logistic regression analyses to evaluate the prognostic and predictive value of patient, surgery, and center characteristics in predicting severe postoperative morbidity 6 months after surgery. RESULTS: This analysis included 368 patients. Severe morbidity occurred in 49 (28 %) of 176 patients who underwent RL versus 41 (21 %) of 192 patients who underwent CL (p = 0.15). In the multivariate analysis, after adjustment for the treatment group (RL vs CL), the risk of severe morbidity increased significantly for patients who had poorer performance status, with an odds ratio (OR) of 1.62 for the 1-point difference in the WHO performance score (95 % CI 1.06-2.47; p = 0.027) and according to the type of surgery (p < 0.001). A focus on complex surgical acts showed significant more morbidity in the RL group than in the CL group at the less experienced centers (OR, 3.31; 95 % CI 1.0-11; p = 0.05) compared with no impact at the experienced centers (OR, 0.87; 95 % CI 0.38-1.99; p = 0.75). CONCLUSION: The findings suggest that the center's experience may have an impact on the risk of morbidity for patients undergoing complex robot-assisted surgical procedures.
