RESUMEN
BACKGROUND: The objective of this study was to assess the trend from open to modern minimally invasive (laparoscopic and robot-assisted) surgical techniques for colorectal cancer (CRC) in Germany, with a particular focus on hospital mortality, postoperative complications, and length of hospital stay. METHODS: A multicenter cross-sectional study was conducted using data from 36 German hospitals, encompassing 1,250,029 cases from January 2019 to December 2023. The study included all hospitalized patients aged ≥ 18 with CRC who underwent surgery. Surgical cases were categorized as open or minimally invasive. Outcomes assessed included in-hospital mortality, morbidity, and hospital length of stay. Statistical analyses involved multivariable logistic and linear regression models adjusted for main diagnosis, metastasis presence, age, sex, and comorbidities. RESULTS: The study included 4525 CRC cases: 2767 underwent open surgery and 1758 underwent minimally invasive surgery (173 robotic). In-hospital mortality was significantly higher in open surgery (6.1% vs. 1.7%). Open surgery was also significantly associated with higher rates of acute post-hemorrhagic anemia (OR: 2.38; 95% CI: 1.87-3.02), respiratory failure (OR: 1.71; 95% CI: 1.34-2.18), and intraoperative and postprocedural complications (OR: 3.64; 95% CI: 2.83-4.70). Average hospital stay was longer for open surgery (19.5 days vs. 11.0 days). CONCLUSION: Despite the advantages of minimally invasive surgery, including reduced mortality, morbidity, and shorter hospital stays, open surgery remains the predominant approach for CRC in Germany. These findings underscore the need for increased adoption of minimally invasive techniques and highlight the potential benefits of shifting toward minimally invasive methods to enhance the overall quality of CRC care.
RESUMEN
BACKGROUND: Over recent years, various advanced minimally invasive techniques have been developed for parathyroidectomy, and there was a universal acceptance of these less invasive procedures by surgeons. This study is designed to compare overall outcomes between endoscopic versus focused, single gland parathyroidectomy using intraoperative rapid parathyroid hormone (ioPTH) changes under general anesthesia in primary hyperparathyroidism (PHPT) patients. METHOD: In this randomized clinical trial, 96 patients diagnosed with PHPT were randomly assigned into two groups endoscopic and focused parathyroidectomy. Baseline clinical and demographical data were collected along with perioperative features. The success rate was evaluated based on ioPTH changes. RESULTS: The ioPTH levels after five minutes in the endoscopic group were significantly lower than the focused group (P = 0.005). The success rate for endoscopic and the focused method was 95.3% and 77.1% during the first five minutes (P = 0.013) and 100% in both groups after ten minutes. A decrease in parathyroid hormone levels was significant in each group but not between each other. Postoperative calcium levels were significantly lower in the focused method (P = 0.042). The focused group also had a significantly shorter operation time than the endoscopic group (P < 0.001). Patient satisfaction with cosmetic outcome was significantly higher in the endoscopic group compared to the focused group. CONCLUSION: The endoscopic technique was superior to the unilateral focused neck exploration parathyroidectomy in the management of single-gland PHPT. Influencing aspects included higher postoperative calcium levels, more rapid success achievement, and satisfactory cosmetic outcomes in the endoscopic group. However, patient selection and accurate adenoma localization are vital in this method.

PURPOSE: Although minimally invasive colorectal surgery has been proven to have a shorter hospital stay and fewer short-term complications than open surgery, the advantages of laparoscopic surgery for colorectal cancer patients undergoing hemodialysis have not been validated. This study compared the outcomes of open and laparoscopic approaches in these patients. MATERIALS AND METHODS: Between January 2007 and December 2020, we retrospectively analyzed the clinical data of 78 hemodialysis patients who underwent curative-intent, elective colorectal surgery. Patients were divided into two groups according to the surgical method: open and laparoscopic. RESULTS: Postoperative morbidity (p = 0.480) and mortality (p = 0.598) rates and length of hospital stay (28.8 vs. 27.5 days, p = 0.830) were similar between the groups. However, laparoscopic surgery patients had a shorter return to clear liquid, full liquid, or soft food time than open surgery patients (p < 0.001, p = 0.007, and p = 0.002, respectively). Disease-free survival and long-term cancer-specific survival rates were also similar between the two groups (p = 0.353 and p = 0.201, respectively). Multivariate analysis revealed that intraoperative blood transfusion was a risk factor for severe complications and mortality (OR 6.055; p = 0.046), and the odds ratio (OR) of laparoscopic surgery was not significantly greater than that of open surgery (OR = 0.537, p = 0.337). CONCLUSION: Although laparoscopic surgery did not result in hemodialysis patients having a shorter postoperative hospital stay, our results suggest that the laparoscopic approach is as safe as open surgery for hemodialysis patients and may be beneficial for shortening the return time to food intake.

PURPOSE: Early mobilization is an essential component of the Enhanced Recovery after Surgery (ERAS®)-pathway. However, a large percentage of patients fail to achieve the ERAS® recommended goal (360 min out of bed from post-operative day 1/POD1). Motivational Interviewing (MI) is an evidence-based type of patient-centered consultation to promote intrinsic motivation. This study aims to evaluate if MI can improve postoperative mobilization. METHODS: This two-arm, patient-blinded pilot randomized controlled trial included ERAS®-patients undergoing elective bowel resections. Conversations were validated by MI Treatment Integrity. Two validated motion sensors (movisens) and self-assessments were used to measure mobilization (POD1-POD3: Time out of bed, time on feet and step count). RESULTS: 97 patients were screened, 60 finally included and randomized. Cumulatively across POD1-3, the intervention group (IG) was longer out of bed than the control group (CG) (median: 685 vs. 420 min; p=0.022). The IG achieved the ERAS®-goal of 360 min/day more frequently across POD1-3 (27.4% vs. 10.61%; p=0.013). Time on feet was 131.5 min/day (median per POD) in IG vs. 95.8 min/day in the CG (p=0.212), step count was 1347 in IG vs. 754 steps/day in CG (p=0.298). CONCLUSION: MI could be conducted low threshold and was well accepted by patients. MI can improve mobilization in the context of ERAS®. Despite better performance, it should be noted that only 27.4% of the IG reached the ERAS®-compliance goal of 360 min/day. The findings of this pilot study stipulate to further test the promising perioperative effects of MI within a multicenter superiority trial. REGISTRATION: This study was registered prospectively in the German Clinical Trials Register on 25.02.2022. Trial registration number is "DRKS00027863".

PURPOSE: Despite mobilization is highly recommended in the ERAS® colorectal guideline, studies suggest that more than half of patients don't reach the daily goal of 360 min out of bed. However, data used to quantify mobilization are predominantly based on self-assessments, for which the accuracy is uncertain. This study aims to accurately measure postoperative mobilization in ERAS®-patients by validated motion data from body sensors. METHODS: ERAS®-patients with elective bowel resections were eligible. Self-assessments and motion sensors (movisens: ECG-Move 4 and Move 4; Garmin: Vivosmart4) were used to record mobilization parameter from surgery to postoperative day 3 (POD3): Time out of bed, time on feet and step count. RESULTS: 97 patients were screened and 60 included for study participation. Self-assessment showed a median out of bed duration of 215 min/day (POD1: 135 min, POD2: 225 min, POD3: 225 min). The goal of 360 min was achieved by 16.67% at POD1, 21.28% at POD2 and 20.45% at POD3. Median time on feet objectively measured by Move 4 was 109 min/day. During self-assessment, patients significantly underestimated their "time on feet"-duration with 85 min/day (p = 0.008). Median number of steps was 933/day (Move 4). CONCLUSION: This study confirmed with objectively supported data, that most patients don't reach the daily mobilization goal of 360 min despite being treated by an ERAS®-pathway with ERAS®-nurse. Even considering an empirically approximated underestimation, the ERAS®-target isn't achieved by more than 75% of patients. Therefore, we propose an adjustment of the general ERAS®-goals into more patient-centered, individualized and achievable goals. REGISTRATION: This study is part of the MINT-ERAS-project and was registered prospectively in the German Clinical Trials Register on 25.02.2022. Trial registration number is "DRKS00027863".

STUDY OBJECTIVE: To investigate whether minimally invasive Sacrohysteropexy (SH) is non-inferior to vaginal hysterectomy (VH) with uterosacral ligament suspension (USLS) in women with symptomatic uterovaginal prolapse. DESIGN: Prospective, randomized, non-inferiority study. SETTING: Tertiary university-based hospital. PATIENTS: A total of 146 patients with uterovaginal prolapse between July 2016 and August 2019. INTERVENTIONS: Patients were randomly assigned in a 1:1 ratio to either laparoscopic or robotic SH surgery or VH with USLS surgery. MEASUREMENTS AND MAIN RESULTS: The primary outcome was prolapse recurrence at 1 year after surgery, defined as prolapse ≥ stage 2 evaluated using the pelvic organ prolapse quantification system, bothersome vaginal bulge symptoms, or retreatment for prolapse. The secondary outcomes included operation time, estimated blood loss, hospital stay, operation-related complications, pain intensity, quality of life, and activities of daily living. Of 146 women who underwent randomization, 73 in the SH group and 73 in the VH with USLS group were analyzed. SH was non-inferior for recurrence compared with VH with USLS (16.4% vs 15.8%, 95% confidence interval: -13.0% to 14.2%). Operating duration and transvaginal length were significantly longer in the SH group, while there were no significant differences in the estimated blood loss, length of hospital stay, or postoperative complication rates. Although perioperative pain intensity was greater from 1 week to 1 month in the SH group, the quality of life and activities of daily living did not differ between the groups throughout postoperative year 1. CONCLUSION: Laparoscopic or robotic SH was non-inferior to VH with USLS for the recurrence of pelvic organ prolapse at the 1-year follow-up.

STUDY OBJECTIVE: Investigating the effect of lumbar lordosis on the relationship between abdominal trocar entry points and major vascular structures. DESIGN: Retrospective cohort. SETTING: Tertiary referral center. PATIENTS: Distances between the skin and the aorta and inferior vena cava at the trocar entry points, both at the umbilicus and 3 cm and 5 cm superior to the umbilicus, were measured at entry angles of 90 and 45 degrees in 101 abdominal computer tomography images. INTERVENTIONS: The relationship of these values with lumbar lordosis was investigated concerning menopausal status, body mass index (BMI), and parity differences. To assess the isolated effect of lumbar lordosis, a simulated 30-degree increase in the lordosis angle was applied to the patients' computed tomography images. The impact of this increased lumbar lordosis angle on the distances between the skin and major vessels was then evaluated at both the umbilical and supraumbilical trocar entry sites. MEASUREMENTS AND MAIN RESULTS: In the tomographic images of all patients, the distances from the skin to vascular structures were measured at a 90-degree entry angle, resulting in measurements of 8.97 cm ± 2.81 at the umbilicus, 10.89 cm ± 3.02 at 3 cm above the umbilicus, and 11.36 cm ± 2.88 at 5 cm above the umbilicus. These distances exhibited significant differences between patients with BMI <30 and BMI ≥30, as well as between premenopausal and postmenopausal patients. However, at a 45-degree entry angle, vascular structures were observed in only a few patients during trocar projection, and no measurable values were determined. In the simulation, it was found that a 1-degree increase in lumbar lordosis angle resulted in a decrease of 0.272 mm ± 0.018 in the distance between the skin and vascular structures at the umbilicus, 0.425 mm ± 0.024 at 3 cm above the umbilicus, and 0.428 mm ± 0.024 at 5 cm above the umbilicus. CONCLUSION: An increase in the degree of lumbar lordosis reduces the distance between trocar entry points and major vascular structures. Along with other factors during Veress and trocar entry, lumbar lordosis should be carefully considered.

PURPOSE: To compare the short- and long-term outcomes of laparoscopic and open abdominal lymph node dissection using propensity score matching (PSM) analysis. METHODS: The subjects of this retrospective analysis were 459 patients who underwent curative resection for esophageal squamous cell carcinoma (ESCC) between May, 2005 and December, 2019, at our hospital. Patients were divided into two groups: the Laparoscopic (Lap group) and the Open (Open group). Post-PSM, 139 patients from each group were selected for the analysis to compare the short- and long-term outcomes between the groups. RESULTS: The Lap group experienced fewer Clavien-Dindo (CD) Grade ≥ 2 complications (28.1% vs. 40.3%, P = 0.04) and lower rates of abdominal surgical site infections (SSI) (2.9% vs. 7.9%, P = 0.02) than the Open group. The number of lymph nodes harvested was similar in the Lap and Open groups (14.8 ± 7.5 vs. 15.7 ± 8.6, P = 0.34). There was no significant difference in 3-year overall survival rates (81.2% vs. 69.5%, P = 0.12) or relapse-free survival rates (61.1% vs. 58.2%, P = 0.54) between the groups. CONCLUSIONS: Laparoscopic abdominal lymph node dissection for ESCC can be performed safely and appears to be beneficial.
RESUMEN
BACKGROUND: Pituitary adenoma (PA), though rare, has seen increased incidence with widespread MRI use, enabling incidental diagnosis. Prevalence is approximately 1 case per 1000 in the general population. PAs are benign neoplasms, constituting 10 to 20% of intracranial tumours. Ectopic pituitary adenoma developed outside the sella turcica is exceptional. It may be hormonally active or not. These are called nonfunctional pituitary adenomas. METHODS: Here is reported a case of a man in his eighties with a nasopharyngeal ectopic pituitary adenoma treated by robot-assisted excision using a combined route. CARE guidelines have been respected. RESULTS: A man in his eighties, asymptomatic, underwent an MRI for dizziness, revealing a nasopharyngeal mass. Despite being asymptomatic, nasofibroscopy revealed a reddish oval-shaped tissue mass attached to the roof of the nasopharynx. Biopsy identified a neuroendocrine tumor G1/G2. Imaging showed no local invasion or distant metastases. A multidisciplinary team decided on a robot-assisted surgical excision through the mouth, coupled with nasal endoscopy. The procedure achieved complete excision with clear margins and no adverse event has occurred. CONCLUSIONS: This unique case involved the successful transoral robot-assisted excision of a nasopharyngeal ectopic pituitary adenoma, highlighting an innovative surgical approach.
RESUMEN
BACKGROUND: To compare the impact of surgical approach on progression free survival (PFS) stratified by histologic type in women diagnosed with stage IA endometrial cancer. METHODS: Myometrial invasion is classified into no myometrial invasion, <50% and ≥50%, with only no myometrial invasion and <50% are included in stage IA patients. A retrospective study is designed by collecting data from women diagnosed as stage IA endometrial cancer from January 2010 to December 2019 in a tertiary hospital. A propensity score is conducted for 1:1 matching in the low-risk histologic patients. Progression free survival and disease-specific survival data are evaluated by the Kaplan-Meier method and compared by the log-rank test in both the whole population and the matched-pair groups. A sub-group analysis is performed to figure out risk factors associated with the effect of surgical approach on PFS and disease-specific survival (DSS). RESULTS: 534 (84.49%) low-risk histologic endometrial cancer women, with 389 (72.85%) operated by minimally invasive surgery and 145 (27.15%) by open approach, and 98 (15.51%) high-risk histology, with 71 (72.45%) by laparoscopy and 27 (27.55%) by open surgery, are included. Compared to open surgery, laparoscopy results in lower progression free survival in low-risk patients before and after matching (p = 0.039 and p = 0.033, respectively), but shows no difference in high-risk patients (p = 0.519). Myometrial invasion is associated with lower progression free survival in laparoscopy in low-risk histology (p = 0.027). CONCLUSION: Surgical approaches influence progression free survival in stage IA low-risk histologic diseases, especially in those with myometrial invasion, but not in high-risk histologic endometrial cancer.

BACKGROUND: Sphincter-preserving techniques like autologous compound platelet-rich fibrin foam have gained popularity, offering potential for better functional outcomes in anal fistula treatment. The present study aimed to evaluate the efficacy and safety of Obsidian RFT®. METHODS: The study conducted a retrospective analysis from January 2018 to December 2022 on patients who received anal fistula closure with Obsidian RTF® at the Department of General Surgery, Medical University of Vienna. Clinical diagnosis, complemented by radiographic imaging, was employed to confirm inconclusive cases. Demographic and fistula characteristics and postoperative data were collected from electronic records following STROCSS criteria. RESULTS: Fifteen patients received Obsidian RFT® treatment for anal fistulas. We found no intra- and postoperative complications. The median hospital stay was 3 days. After a median follow-up of 32 months, a closure rate of 53.3% was detected. Non-significant differences were observed in various variables, yet trends emerged, indicating associations between abscess presence and non-healing fistulas. A distinct age threshold (≥ 42.7 years) served as an indicator for an inability to achieve anal fistula cure. CONCLUSION: Obsidian RFT® represents a safe, minimally invasive operative procedure. Approximately half the patients experienced healing, with better outcome in a younger population. TRIAL REGISTRATION: Ethical Approval number Medical University of Vienna (#1258/2018). This study was registered retrospectively in ClinicalTrials.gov (NCT06136325).

BACKGROUND: Surgical treatment helps to restore stability of the elbow in patients with posterolateral rotatory instability (PLRI). The anconeus muscle is one of the most important active stabilizers against PLRI. A minimally invasive anconeus-sparing approach for lateral ulnar collateral ligament (LUCL) reconstruction using a triceps tendon autograft has been previously described. The purpose of this study was to evaluate the outcome of this intervention and identify risk factors that influenced the clinical and patient-reported outcomes. METHODS: Sixty-one patients with chronic PLRI and no previous elbow surgery who underwent surgical reconstruction of the LUCL using a triceps tendon autograft in a minimally invasive anconeus-sparing approach during 2012 and 2018 were evaluated. Outcome measures included a clinical examination and the Oxford Elbow Score (OES) and the Mayo Elbow Performance Score (MEPS) questionnaires. Subjective patient outcomes were evaluated with the visual analog scale (VAS) for pain and the Subjective Elbow Value (SEV). Integrity of the common extensor tendons and centering of the radial head were assessed preoperatively on standardized magnetic resonance images (MRIs). RESULTS: Fifty-two patients were available at final follow-up. The mean age of patients was 51 ± 12 years with a mean follow-up of 53 ± 14 months (range 20-76). Clinical examination after surgery (n = 41) showed no clinical signs of instability in 98% of the patients (P < .001) and a nonsignificant improvement in range of motion. OES, MEPS, and VAS scores averaged 40 ± 10 of 48 points, 92 ± 12 of 100 points, and 1 ± 2 points, respectively, all corresponding with good or excellent outcomes. The SEV was 88%, indicating very high satisfaction with the surgery. Only 1 patient had revision surgery due to pain, and there were no reported postoperative complications in this cohort. A radial head subluxation in the MRI correlated significantly with worse postoperative outcomes. CONCLUSIONS: The anconeus-sparing minimally invasive technique for posterolateral stabilization of the elbow using a triceps tendon autograft is an effective and safe treatment for chronic posterolateral instability of the elbow with substantial improvements in elbow function and pain relief with a very low rate of persistent clinical instability.

Accurately mapping the temperature during ablation is crucial for improving clinical outcomes. While various sensor configurations have been suggested in the literature, depending on the sensors' type, number, and size, a comprehensive understanding of optimizing these parameters for precise temperature reconstruction is still lacking. This study addresses this gap by introducing a tool based on a theoretical model to optimize the placement of fiber Bragg grating sensors (FBG) within the organ undergoing ablation. The theoretical model serves as a general framework, allowing for adaptation to various situations. In practical application, the model provides a foundational structure, with the flexibility to tailor specific optimal solutions by adjusting problem-specific data. We propose a nonlinear and nonconvex (and, thus, only solvable in an approximated manner) optimization formulation to determine the optimal distribution and three-dimensional placement of FBG arrays. The optimization aims to find a trade-off among two objectives: maximizing the variance of the expected temperatures measured by the sensors, which can be obtained from a predictive simulation that considers both the type of applicator used and the specific organ involved, and maximizing the squared sum of the distances between the sensor pairs. The proposed approach provides a trade-off between collecting diverse temperatures and not having all the sensors concentrated in a single area. We address the optimization problem through the utilization of approximation schemes in programming. We then substantiate the efficacy of this approach through simulations. This study tackles optimizing the FBGs' sensor placement for precise temperature monitoring during tumor ablation. Optimizing the FBG placement enhances temperature mapping, aiding in tumor cell eradication while minimizing damage to surrounding tissues.
RESUMEN
BACKGROUND: Gynecomastia is a benign condition that develops due to the proliferation of breast tissue in men. Surgical excision is the most effective treatment method. Minimally invasive techniques can be used to avoid visible scarring. We evaluated the efficacy and safety of air-assisted subcutaneous mastectomy in the treatment of gynecomastia. PATIENT AND METHODS: 10 patients with gynecomastia underwent air-assisted subcutaneous mastectomy and liposuction through a single axillary incision, between June 2022 and February 2023. Demographic and clinical data of the patients, duration of surgery, and complications were recorded. The satisfaction levels of the patients regarding physical appearance, mental status, and social environment were measured. The body Q questionnaire was performed preoperatively and in the postoperative third month. RESULTS: The median age was 26 (range, 18-54). Surgical excision was measured as a median of 69 gr (range, 41-177), and liposuction volume was measured as a median of 210 ccs (range, 63-400). The median operation time was 50 minutes (range, 21-60) for excision and 21 minutes (range, 20-75) for liposuction. Body, chest, and nipples related appearance satisfaction levels were measured preoperatively as a median of 44 (range, 36.5-52), 31 (range, 27.5-39), and 51.5 (range, 21-69.8) points vs postoperatively as 92 (range, 92-100), 93 (range, 93-94.8) and 90 (range, 90-100) points, respectively. The patients had a median follow-up of 6 months (range, 3-11). No complications were observed during the follow-up period. CONCLUSION: Air-assisted subcutaneous mastectomy and liposuction is a feasible technique that may provide good cosmetic outcomes by avoiding anterior chest wall scarring.

AIM: In this technical note we describe a simplified totally transabdominal technique to perform a single stapled end-to-end colorectal anastomosis without the need for transanal transection, linear stapler line resection, purse string or dog-ear suturing. METHOD: The rationale and the technique itself are first explained by using a schematic design. Next, step-by-step pictures of one of our cases show the feasibility and advantages of this technique. At the end, the limits of this technique are illustrated. RESULTS: The technique was used for 20 colorectal anastomosis, 9 benign and 11 oncological cases. Median age was 68 years and average BMI was 28 kg/m2. Risk factors for anastomotic leakage were reported in 10 cases. The bow tie technique was performed in every case and the linear stapler line was entirely resected in all cases. No positive air leak test or anastomotic leakage was reported. CONCLUSIONS: The bow tie technique is a feasible technique to perform an end-to-end single stapled colorectal anastomosis with promising results on anastomotic leakage. Further research with larger prospective data collection is necessary to validate this technique and show its potential benefit on anastomotic leakage.
RESUMEN
PURPOSE: To evaluate the results of a minimally invasive combined endoscopic and eyelid crease/medial suprabrow incision approach in collaboration with oculoplastic and sinus surgeons for the treatment of recurrent/recalcitrant sino-orbital mucoceles. METHODS: Eighteen cases of recurrent/recalcitrant sino-orbital mucoceles, treated in collaboration with oculoplastic and sinus surgeons at the University of Michigan, were retrospectively reviewed. The recurrence of mucocele, reduction in proptosis, and complications were evaluated. RESULTS: The mean age at the time of surgery was 49 years (range: 17-76 years). All cases had a history of previous sinus or orbital surgeries for mucoceles. Among 18 cases, eight were due to chronic sinus infections, six due to trauma, three due to Schneiderian papilloma, and one case was secondary to an inflammatory sinus disease. Thirteen cases (72%) presented with orbital or facial cellulitis, while five cases (38%) experienced periocular swelling and limited extraocular motility. Following a mean follow-up of 19 months (range: 1-76 months)), recurrence was observed in two cases (11%): one in a cystic fibrosis patient with chronic sinusitis, and the other in a case of Schneiderian papilloma. The mean pre-operative proptosis in the affected eye was 2.78 mm, with an average decrease of 2.33 mm after surgery. Complications occurred in two cases, including one case of hypoesthesia in the forehead and one case of post-operative strabismus. CONCLUSION: Our series of 18 cases of recurrent/recalcitrant mucoceles, with only two cases of recurrence, demonstrates that this minimally invasive approach can be successfully employed for advanced sino-orbital disease, with a low rate of adverse outcomes and aesthetically pleasing results.
RESUMEN
BACKGROUND: Minimally invasive surgical (MIS) osteotomies are increasing as a surgical option for treating midfoot and forefoot conditions. This study aimed to evaluate the impact of each burr pass on the degree of correction, gap size, and alignment in MIS Akin and first metatarsal dorsiflexion osteotomies (DFO). METHODS: MIS Akin and first metatarsal DFO were performed on ten cadaveric specimens. Fluoroscopic measurements included the metatarsal dorsiflexion angle (MDA), dorsal cortical length (MDCL), first phalangeal medial cortical length (PCML) and proximal to distal phalangeal articular angle (PDPAA). RESULTS: The average decrease in PCML with each burr pass was as follows: 1.53, 1.33, 1.27, 1.23 and 1.13 mm at the 1st to 5th pass, respectively. The MDCL sequentially decreased by 1.80, 1.59, 1.35, 0.75, and 0.60 mm. The MDA consistently decreased, and the PDPAA incrementally became more valgus oriented. CONCLUSION: On average, a first metatarsal dorsal wedge resection of 4.7 mm and first phalangeal medial wedge resection of 2.9 mm was achieved after 3 and 2 burr passes, respectively. This data may aid surgeons determine the optimal number of burr passes required to achieve the desired patient-specific surgical correction.

BACKGROUND: Pulmonary sequestration (PS) is a rare congenital lower airway malformation. This study presents the clinical and imaging features and surgical outcomes of PS in adults, and compare the safety and feasibility of minimally invasive surgery versus open thoracotomy for PS. METHODS: Adult patients with PS treated at our center from July 2011 to September 2021 were included. Information regarding the patient demographics, clinical and CT features, arterial supply and venous drainage, and surgical outcomes were collected. RESULTS: Ninety seven patients were included. The most common CT findings were mass lesions (50.5%) and cystic lesions (20.6%). The vast majority of the lesions (96 out of 97) were located close to the spine in the lower lobes (left vs. right: 3.6 vs. 1). Arterial supply was mainly provided by the thoracic aorta (87.4%) and abdominal aorta (10.5%). Intralobar and extralobar PS accounted for 90.7% and 9.3% of the patients, respectively. Three (4.5%) patients who underwent minimally invasive surgery were converted to open thoracotomy due to dense adhesions. Though no significant differences regarding operative time (P = 0.133), the minimally invasive surgery group was significantly better than the open thoracotomy group regarding intraoperative blood loss (P = 0.001), drainage volume (P = 0.004), postoperative hospital days (P = 0.017) and duration of chest drainage (P = 0.001). There were no cases of perioperative mortality. Only four (4.1%) patients developed postoperative complications, and no significant difference existed between the two groups. CONCLUSION: Our study revealed PS can present with a variety of different clinical and radiologic manifestations. Clinicians should consider the possibility of PS when diagnosing a lesion in the lower lobes close to the spine. Moreover, minimally invasive surgery is a safe and effective treatment modality for the treatment of PS in an experienced center.

OBJECTIVE: In recent years, the minimally invasive surgical treatment methods of ureteropelvic junctional obstruction (UPJO) have been diverse, but its approach and choice of surgical method are controversial. This network meta-analysis (NMA) aimed to compare the safety and effectiveness of minimally invasive surgeries for UPJO, which included robotic or laparoscopic pyeloplasty, via the retroperitoneal or transperitoneal approach. METHODS: We searched relevant RCTs in PubMed, Embase, Web of Science, the Cochrane Library, and CNKI. To assess the results of operative time, complications and success rate, pairwise, and NMA were carried out. The models for analyses were performed by Revman 5.3, Addis V1.16.8 and R software. RESULTS: A total of 6 RCTs were included in this study involving four types of surgeries: transperitoneal laparoscopic pyeloplasty (T-LP), retroperitoneal laparoscopic pyeloplasty (R-LP), robot-assisted transperitoneal pyeloplasty (T-RALP), and robot-assisted retroperitoneal pyeloplasty (R-RALP). This study consisted of 381 patients overall. T-RALP had a quicker operational duration (SMD = 1.67, 95% CI 0.27-3.07, P = 0.02) than T-LP. According to the NMA's consistency model, T-RALP improved the surgical success rate more than T-LP (RR = 6303.19, CI 1.28 to 1.47 × 1011). Ranking probabilities indicated that RALP could be the better option than LP and retroperitoneal approach was comparable to transperitoneal approach. All procedures had high surgical success rates and few complications. CONCLUSION: Outcomes for four surgical approaches used in the UPJO were comparable, with T-RALP being the most recommended approach. Selection between the transperitoneal and retroperitoneal approaches primarily depended on the surgeon's preference. Higher quality evidence is needed to further enhance the result.

Minimally invasive surgical procedures aim at optimal wound healing, a reduction of postoperative morbidity and, thus, at increased patient satisfaction. The present article reviews the concept of minimal invasiveness in gingival augmentation and root coverage procedures, and critically discusses the influencing factors, technical and nontechnical ones, and relates them to the underlying biological mechanisms. Furthermore, the corresponding outcomes of the respective procedures are assessed and evaluated in relation to a possible impact of a minimized surgical invasiveness on the clinical, aesthetic, and patient-related results.
