Preservation of the celiac branch of the vagus nerve reduces the incidence of postoperative diarrhea in gastric cancer: a cohort study.

BACKGROUND: To investigate the short-term and long-term outcomes of preserving the celiac branch of the vagus nerve during laparoscopic distal gastrectomy. METHODS: A total of 149 patients with prospective diagnosis of gastric cancer who underwent laparoscopic-assisted distal gastrectomy (LADG) combined with Billroth-II anastomosis and D2 lymph node dissection between 2017 and 2018 were retrospectively analyzed. The patients were divided into the preserved LADG group (P-LADG, n = 56) and the resected LADG group (R-LADG, n = 93) according to whether the vagus nerve celiac branch was preserved. We selected 56 patients (P-LADG, n = 56) with preservation of the celiac branch of the vagus nerve and 56 patients (R-LADG, n = 56) with removal of the celiac branch of the vagus nerve by propensity-matched score method. Postoperative nutritional status, weight change, short-term and long-term postoperative complications, and gallstone formation were evaluated in both groups at 5 years of postoperative follow-up. The status of residual gastritis and bile reflux was assessed endoscopically at 12 months postoperatively. RESULTS: The incidence of diarrhea at 5 years postoperatively was lower in the P-LADG group than in the R-LADG group (p < 0.05). In the multivariate logistic analysis, the removal of vagus nerve celiac branch was an independent risk factor for the occurrence of postoperative diarrhea (odds ratio = 3.389, 95% confidential interval = 1.143-10.049, p = 0.028). In the multivariate logistic analysis, the removal of vagus nerve celiac branch was an independent risk factor for the occurrence of postoperative diarrhea (odds ratio = 4.371, 95% confidential interval = 1.418-13.479, p = 0.010). CONCLUSIONS: Preservation of the celiac branch of the vagus nerve in LADG reduced the incidence of postoperative diarrhea postoperatively in gastric cancer. TRIAL REGISTRATION: This study was registered with the Ethics Committee of the First Affiliated Hospital of Dalian Medical University in 2014 under the registration number: LCKY2014-04(X).

Robot-Assisted Radical Prostatectomy by the Hugo Robotic-Assisted Surgery (RAS) System and the da Vinci System: A Comparison between the Two Platforms.

OBJECTIVE: In a previous study, we proved that an experienced urologist is more likely to adapt to the Hugo RAS system. Based on this, we further examine various parameters in this study. Parameters included in this study consisted of console time, functional outcomes, and oncological outcomes. MATERIALS AND METHODS: A total of 60 patients who underwent robot-assisted radical prostatectomy (RARP) performed by a single surgeon using the da Vinci (DV) system (n = 30) or the Hugo RAS system (n = 30) between March 2023 and August 2023 were included in the analysis. The intraoperative operative time was categorized into vesicourethral anastomosis time and overall console time. Functional and oncological outcomes were documented at the 1st and 3rd postoperative months. Parametric and non-parametric methods were adopted after checking skewness and kurtosis, and an α value of 5% was used to determine the significance. RESULTS: The vesicourethral anastomosis time was significantly lengthened (Hedge's g: 0.87; 95% confidence interval (CI): 0.34-1.39; J factor = 0.987). However, the overall console time was not affected. The functional (postoperative 3rd month: p = 0.130) and oncological outcomes (postoperative 3rd month: p = 0.103) were not significantly different. We also found that the adverse effect on surgical specimens and positive surgical margins was not affected (p = 0.552). CONCLUSION: During the process of adaptation, although intricate motions (such as the vesicourethral anastomosis time) would be lengthened, the overall console time would not change remarkably. In this process, the functional and oncological outcomes would not be compromised. This encourages urologists to adopt the Hugo RAS system in RARP if they have previous experiences of using the DV system, since their trifecta advantage would not be compromised.

Post-parotidectomy facial nerve rehabilitation outcomes: Comparison between benign and malignant neoplasms.

BACKGROUND: Facial nerve dysfunction can be a devastating trouble for post-parotidectomy patients. OBJECTIVE: To assess rehabilitation outcomes concerning patients with post-parotidectomy facial nerve dysfunction, comparing benign versus malignant neoplasms. METHODS: Prospective study enrolling adults who underwent parotidectomy with facial nerve sparing between 2016 and 2020. The Modified Sunnybrook System (mS-FGS) was used for facial assessments. Physiotherapy began on the first post-operative day with a tailored program of facial exercises based on Neuromuscular Retraining, to be performed at home 3 times/day. From the first outpatient consultation, Proprioceptive Neuromuscular Facilitation was added to the treatment of cases with moderate or severe facial dysfunctions. RESULTS: Benign and malignant groups had a statistically significant improvement in mS-FGS (p < 0.001 and p = 0.005, respectively). There was no significant difference between groups regarding treatment duration or number of physiotherapy sessions performed. The history of previous parotidectomy resulted in more severe initial dysfunctions and worse outcome. Age over 60 years and initially more severe dysfunctions impacted the outcome. CONCLUSION: Patients with benign and malignant parotid neoplasms had significant and equivalent improvement in postoperative facial dysfunction following an early tailored physiotherapy program, with no significant difference in the final facial score, treatment duration, or number of sessions required.

Total Margin Control Is Superior to Traditional Margin Assessment for Treatment of Low-Stage Penile Squamous Cell Carcinoma.

PURPOSE: Penile cancer is rare, with significant morbidity and limited literature assessing utility of peripheral and deep en face margin assessment (PDEMA) vs traditional margin assessment (vertical sections) on treatment outcomes. MATERIALS AND METHODS: This was a 32-year retrospective multicenter cohort study at 3 academic tertiary care centers. The cohort consisted of 189 patients with histologic diagnosis of in situ or T1a cutaneous squamous cell carcinoma of the penis at Brigham and Women's, Massachusetts General Hospital (1988-2020), and Memorial Sloan Kettering Cancer Center (1995-2020) treated with PDEMA surgical excision, excision/circumcision, or penectomy/glansectomy. Local recurrence, metastasis, and disease-specific death were assessed via multivariable Cox proportional hazard models. RESULTS: The cohort consisted of 189 patients. Median age at diagnosis was 62 years. Median tumor diameter was 1.3 cm. The following outcomes of interest occurred: 30 local recurrences, 13 metastases, and 5 disease-specific deaths. Primary tumors were excised with PDEMA (N = 30), excision/circumcision (N = 110), or penectomy/glansectomy (N = 49). Of patients treated with traditional margin assessment (non-PDEMA), 12% had narrow or positive margins. Five-year proportions were as follows with respect to local recurrence-free survival, metastasis-free survival, and disease-specific survival/progression-free survival, respectively: 100%, 100%, and 100% following PDEMA; 82%, 96%, and 99% following excision/circumcision; 83%, 91%, and 95% following penectomy/glansectomy. A limitation is that this multi-institutional cohort study was not externally validated. CONCLUSIONS: Initial results are encouraging that PDEMA surgical management effectively controls early-stage penile squamous cell carcinoma.

Rol de los cuidados perioperatorios guiados por protocolo para mejorar la recuperación tras la cirugía de cáncer de cabeza y cuello: experiencia institucional / Role of protocol-guided perioperative care to enhance recovery after head and neck neoplasm surgery: An institutional experience

Antecedentes: Enhanced recovery after surgery (ERAS) mejora la recuperación tras la cirugía. El objetivo de este estudio fue determinar si ERAS causa una reducción de la estancia hospitalaria y mejora la recuperación funcional global tras la cirugía de cáncer de cabeza y cuello. Métodos Realizamos un estudio prospectivo de control de casos histórico tras la aplicación de ERAS. La base de datos del hospital seleccionó 50 pacientes elegibles confirmados para el grupo control no ERAS, incluyéndose prospectivamente 54 pacientes en el grupo ERAS. El resultado primario fue el tiempo transcurrido hasta la disposición al alta (TRD), siendo los resultados secundarios la duración de la estancia hospitalaria (DEH), la tasa de reingreso de hasta 30 días y la puntuación QoR-15 (Quality of recovery). Los datos fueron comparados mediante pruebas paramétricas y no paramétricas adecuadas. Resultados Los datos demográficos basales de los pacientes fueron comparables entre ambos grupos. Los pacientes del grupo ERAS reflejaron un TRD significativamente más breve, en comparación con el grupo no ERAS: 8 (6-10) frente a 11 (8-16); p=0,002. La DEH fue también significativamente más corta en el grupo ERAS en comparación con el grupo no ERAS (8 [7-11] frente a 12 [9-17]; valor p=0,002). El reingreso en el plazo de 30 días no fue diferente, con una cifra de 6 pacientes en cada grupo. La puntuación QoR-15 fue estadísticamente mejor en el grupo ERAS (94,88±12,50) en comparación con el grupo no ERAS (85,44±12,68; p <0,001). Conclusión La implementación del programa ERAS redujo el TRD y la DEH, mejorando la puntuación QoR-15 sobre el resultado de la recuperación reportado por el paciente en las cirugías de cáncer de cabeza y cuello.

Background: Enhanced recovery after surgery (ERAS) improve recovery after surgery. This study aimed to determine whether ERAS leads to a decrease in stay in the hospital and improves global and functional recovery after head and neck neoplasms surgery. Methods We performed a prospective case and historical control study after the ERAS application. The hospital database selected 50 confirmed eligible patients in control non-ERAS group. Prospectively 54 patients were included in the ERAS group. The primary outcome was time to readiness for discharge (TRD); secondary outcomes were the length of stay (LOS), readmission rate of up to 30 days and Quality of recovery score QoR-15. Data were compared with appropriate parametric and nonparametric tests. Results Baseline demographic data of patients were comparable between the two groups. Patients in ERAS group had significantly shorter TRD compared to the non-ERAS group 8 (6-10) versus 11 (8-16); P=.002. LOS was also significantly shorter in the ERAS group compared to the non-ERAS group (8 [7-11] versus 12 [9-17]; P=.002). Readmission at 30-days was no different, with six patients in each group. QoR-15 score was statistically better in ERAS group (94.88±12.50) compared to non-ERAS group (85.44±12.68; P<.001). Conclusion Implementing the ERAS programme decreased TRD and LOS and improved patient-reported recovery outcome QoR-15 in head and neck neoplasms surgery. (AU)

Recent Developments in the Treatment of Pancreatic Cancer.

Pancreatic duct adenocarcinoma is currently the sixth-leading cause of cancer death worldwide and the fourth in Europe, with a continuous increase in annual lethality in Portugal during the last two decades. Surgical en-bloc resection of the tumor with microscopic-negative margins and an adequate lymphadenectomy is the only possibility of long-term survival. As this type of cancer is a systemic disease, there is a high rate of recurrence even after curative resection, turning systemic therapy the core of its management, mostly based on chemotherapy. Neoadjuvant strategies for nonmetastatic disease showed significant improvement in overall survival compared with upfront surgery, namely in borderline resectable disease. Moreover, these strategies provided downstaging in several situations allowing R0 resections. Under these new oncologic strategies, several recent surgical issues were introduced, namely more aggressive vascular resections and even tumor resections in oligometastatic disease. This review revisits the state-of-the-art of surgical and oncological interventions in pancreatic duct adenocarcinoma and highlights recent advances in the field aiming to achieve higher survival rates.

Robot-assisted radical prostatectomy using hugo RAS system: The pioneer experience in Taiwan and Northeast Asia.

BACKGROUND: Among the novel robotic platforms, the Hugo RAS system is the second most studied platform, next to the da Vinci system, and we aim to address our experiences in radical prostatectomy (RP) with the Hugo RAS system. METHODS: We recorded our first 12 cases of prostate cancer undergoing RP with the Hugo RAS system. The median console time was 145 min and median hospital stay was 7 days. Hedge' g was applied to search for the cut-off case in four parameters in surgeries. RESULTS: Pre-console preparation was significantly improved after the first seven cases, and the console time was remarkably shortened after the first two cases. The intraoperative pause for trouble shooting was remarkably shortened after the first three cases. CONCLUSIONS: We found that RP with the Hugo RAS system was feasible, and the learning curve was short as surgeons may benefit from the previous experience with the da Vinci system.

A case study of the pathology on a rare case of scalp lymphangioma in an adult patient.

Lymphangiomas are congenital malformations of the lymphatic system, mostly well-circumscribed and cystic. Although many theories were proposed to explain etiology, it is still controversial. Most of these lesions are found in the cervicofacial region, while the scalp is considered a scarce location, with only a few reported cases in the literature. Herein, we report a case of scalp lymphangioma in a 33-year-old male, which unexpectedly and significantly progressed in size over one year. The MRI scan characteristics were unique compared to the literature description of the lymphangioma, as it appeared hypointense in both T1WI and T2WI with inhomogeneous contrast enhancement, eventually consistent with lymphangioma on histopathology. The patient underwent surgical excision of the mass without any recurrence over a follow-up period of 1 year.

One-Step Robot-Assisted Complete Urinary Tract Extirpation in Man with End-Stage Renal Disease on Dialysis: The First Case Report.

Urothelial carcinoma (UC) could be observed in urinary bladder (UBUC) and upper urinary tracts (UTUC). In the National Comprehensive Cancer Network guidelines for bladder cancer, extirpative surgery is indicated in certain cases. However, some extreme cases might also need the extirpation of the majority of the urinary tract, which is called complete urinary tract extirpation (CUTE). We present a patient diagnosed with high-grade UBUC and UTUC. He underwent dialysis for end-stage renal disease (ESRD) at the same time. Considering his non-functional kidneys and removing his high-risk urothelium at the same time, we performed robot-assisted CUTE to extirpate both his upper urinary tracts, urinary bladder, and prostate. In our experience, the console time was not significantly elongated, and the perioperative course was uneventful. To our knowledge, this is the first case report adopting a robotic system in such an extreme case. We conclude that robot-assisted CUTE is worth further study regarding its oncological survival outcomes and perioperative safety in patients with ESRD on dialysis.

Dermoglandular advancement-rotation flap for conservative treatment of breast cancer - description of technique, objective and subjective assessments.

Objective: to describe and evaluate the dermoglandular advancement-rotation flap with no contralateral surgery as a technique for the conservative treatment of breast cancer when skin or a large proportion of gland requires resection. Patients/Methods: 14 patients with breast tumors with a mean size of 4.2 cm and need for skin resection. The resection area is included within an isosceles triangle, with its apex located on the areola, which is the pivot for rotation of a dermoglandular flap released through a lateral extension along that triangle base. Symmetry before and after radiotherapy was objectively assessed by authors using the BCCT.core software, as well as subjectively by three experts and patients themselves using the Harvard scale. Results: Experts considered the breast symmetry results to be excellent/good for 85.7% of patients in the early post-operative period and 78.6% in the late post-operative period. Excellent/good ratings provided by BCCT.core software amounted to 78.6% of cases in the early post-operative period and 92.9% in the late post-operative period. Symmetry was rated as excellent/good by 100% of patients. Conclusion: Dermoglandular advancement-rotation flap technique with no contralateral surgery provides good symmetry when a large proportion of skin or gland requires resection on breast conservative cancer treatment.

Determining the optimal radiation-surgery interval (RSI) for oncologic proctectomy following radiotherapy for rectal adenocarcinoma.

Preoperative radiotherapy has improved outcomes in rectal cancer patients, however, the optimal interval between radiation and proctectomy is unknown. A review of contemporary literature suggests an 8-12 week interval between radiation and surgery likely improves tumor response rates for rectal cancer patients undergoing proctectomy, which may convey modest improvements in long-term oncologic outcomes. Prolonged radiation-surgery intervals may expose surgeons to pelvic fibrosis, however, which may impact later-term proctectomies and compromise perioperative and oncologic outcomes.

The Role of High-Resolution Ultrasound in the Assessment of Surgical Candidates for Transoral Endoscopic Thyroidectomy Via Vestibular Approach (TOETVA).

The approach of surgical techniques has evolved significantly over the last decade, with natural orifice surgeries replacing traditional open approaches. In 2016, Angkoon Anuwong, in Thailand, demonstrated it was possible to perform thyroidectomies in a series of patients by a transoral endoscopic ap-proach - transoral endoscopy thyroidectomy vestibular approach (TOETVA) - with similar complication rates when compared to conventional surgeries. This transoral surgery has become a safe alternative with better cosmetic results, compared to conventional open-route procedures, like Kocher cervi-cotomy. Indeed, it is an option to surgically treat neoplastic and functional thyroid diseases. The technique is performed through a median incision in the oral vestibule, plus two bilateral incisions, followed by the insertion of three trocars, one centrally for a camera, and two laterally for working instruments. Although revolutionary, TOETVA has its technical limitations. Therefore, it is important to precisely define the preoperative eligibility criteria for this type of surgical approach. High-resolution ultrasound is the first imaging modality for the assessment of thyroid nodules, lymph node metastases and surgical field. The aim of this article is to outline the sonographic technique and the role of high-resolution ultrasound in the presurgical evaluation of TOETVA.

Renal function outcome after selective bladder-preserving tetramodality therapy consisting of maximal transurethral resection, induction chemoradiotherapy and consolidative partial cystectomy in comparison with radical cystectomy for patients with muscle-invasive bladder cancer: a two-centre retrospective study.

OBJECTIVE: To compare renal function (RF) outcomes after bladder-preserving tetramodal therapy against muscle-invasive bladder cancer (MIBC) to those after radical cystectomy (RC). METHODS: This study included 95 patients treated with tetramodal therapy consisting of transurethral bladder tumour resection, chemoradiotherapy and partial cystectomy (PC) and 300 patients treated with RC. The annual change in the estimated glomerular filtration rate (eGFR) was compared using the linear mixed model. Renal impairment was defined as a >25% decrease from the pretreatment eGFR, and renal impairment-free survival (RIFS) was calculated. The association between treatment type and renal impairment was assessed. RESULTS: The number of patients who received neoadjuvant chemotherapy was 8 (8.4%) in the tetramodal therapy group and 75 (25.0%) in the RC group. After the inverse probability of treatment weighting adjustments, the baseline characteristics were balanced between the treatment groups. The mean eGFR before treatment in tetramodal therapy and RC groups was 69.4 and 69.6 mL/min/1.73 m2 and declined with a slope of -0.7 and -1.5 mL/min/1.73 m2/year, respectively. The annual deterioration rate of post-treatment eGFR in the tetramodal therapy group was milder than in the RC group. The 5-year RIFS rate in the tetramodal therapy and the RC groups was 91.2 and 85.2%, respectively. Tetramodal therapy was an independent factor of better RIFS compared with RC. CONCLUSIONS: RF was better preserved after tetramodal therapy than after radical therapy; however, even after tetramodal therapy, the eGFR decreased, and a non-negligible proportion of patients developed renal impairment.
