We removed the lesions, and the cut edges of the tumors were negative. Thus, we deduced that ultrasound-guided ONSS is suitable for the cases with obscure tumor boundary or multiple lesions. It could achieve the purpose of thoroughly removing lesions, as well as to expand the application range of nephron sparing surgery.展开更多

Methods:From August 1997 to October 2008,48 cases of small renal cell carcinomas were confirmed by surgery and pathology,and reviewed retrospectively. Of the 48 cases,there was 1 patient with bilateral tumors,8 with solitary kidney tumors,1 with unilateral tumor and a damaged contralateral kidney,and 38 with unilateral tumors and a normal contralateral kidney; 9 underwent tumor enucleation and the remaining patients received partial nephrectomy. Results:There were no local tumor recurrences and/or tumor metastasis at a mean followup of 60 months. Conclusion:Confirming conclusions from other centers,we have found that nephron-sparing surgery is an effective treatment for small renal cell carcinomas.展开更多

This evolution followed a guideline whose milestones are: 1) the surgical approach and implantation technique (ex: detachment of the greater trochanter);2) to use or not to use cement;3) the evolution of materials (titanium, ceramic, x-linked polyethylene);4) the identification of the debris-disease rather than the cement-disease;5) studies focused on bone-prosthesis interaction and biological phenomena related. Between those studies, the authors consider crucial the introduction of tissue sparing surgery and femoral neck preserving rationale, concepts to which they have devoted their scientific research and clinical experience for over the last 30 years, from 1980 to nowadays.展开更多

Methods: Clinicopathologic data on a total of 90 patients with stage I recurrent ovarian cancer collected under the central pathological review system were subjected to survival analyses. Patients were divided into 2 groups: 1) FSS (N = 11), 2) Radical (N = 79). Results: Five-year overall survival rates of patients in the two groups were as follows: 40.8% (FSS)/44.2% (Radical), respectively. There was no significant difference in overall survival among the groups (P = 0.887). Additionally, three-year postrecurrence survival rates of patients in the two groups were 24.8% (FSS) and 25.3% (Radical) (P = 0.730). Furthermore, we accumulated 137 patients {FSS (N = 58), Radical group (N = 79)} with stage I recurrent ovarian cancer from the current study and six representative reports in the literature. Patients who experienced recurrence in the remaining ovary alone (FSS) showed a more favorable prognosis than those who had extra-ovarian site recurrence (overall survival: P = 0.021, postrecurrence survival: P = 0.069). Conclusions: Although our retrospective analysis was very preliminary, we could propose the hypothesis that patients with stage I recurrent ovarian cancer who undergo FSS may not show poorer survival rates than patients who receive radical surgery.展开更多

However, there is worry concerning its oncological safety and surgical outcome in terms of postoperative complications. The authors reviewed the literature to evaluate the oncological safety, patient selection, surgical techniques, and also to identify the factors influencing postoperative outcome and complication rates. Patient selection and safety related to NSM are based on oncological and anatomical parameters. Among the main criteria, the oncological aspects include the clinical stage of breast cancer, tumor characteristics and location including small, peripherally located tumors, without multicentricity, or for prophylactic mastectomy. Surgical success depends on coordinated planning with the oncological surgeon andcareful preoperative and intraoperative management. In general, the NSM reconstruction is related to autologous and alloplastic techniques and sometimes include contra-lateral breast surgery. Choice of reconstructive technique following NSM requires accurate consideration of various patient related factors, including: breast volume, degree of ptosis, areola size, clinical factors, and surgeon's experience. In addition, tumor related factors include dimension, location and proximity to the nipple-areola complex. Regardless of the fact that there is no unanimity concerning the appropriate technique, the criteria are determined by the surgeon's experience and the anatomical aspects of the breast. The positive aspects of the technique utilized should include low interference with the oncological treatment, reproducibility, and long-term results. Selected patients can have safe outcomes and therefore this may be a feasible option for early breast cancer management. However, available data demonstrates that NSM can be safely performed for breast cancer treatment in selected cases. Additional studies and longer follow-up are necessary to define consistent selection criteria for NSM.展开更多

The combination of TME with radiochemotherapy has led to a reduction of local failure to less than 5%. On the other hand, surgery for rectal cancer is also impaired by the potential for a significant loss in quality of life. This is a new challenge surgeons should think about nowadays: If patients live more, they also want to live better. The fight against cancer cannot only be based on survival, recurrence rate and other oncological endpoints. Patients are also asking for a decent quality of life. Rectal cancer is probably a paradigmatic example: Its treatment is often associated with the loss or severe impairment of faecal function, alteration of body anatomy, urogenital problems and, sometimes, intractable pain. The evolution of laparoscopic colorectal surgery in the last decades is an important example, which emphasizes the importance that themes like scar, recovery, pain and quality of life might play for patients. The attention to quality of life from both patients and surgeons led to several surgical innovations in the treatment of rectal cancer: Sphincter saving procedures, reservoir techniques(pouch and coloplasty) to mitigate postoperative faecal disorders, nerve-sparing techniques to reduce the risk for sexual dysfunction. Even more conservative procedures have been proposed alternatively to the abdominal-perineal resection, like the local excisions or transanal endoscopic microsurgery, till the possibility of a wait and see approach in selected cases after radiation therapy.展开更多

The recovery was uneventful and mean length of postoperative stay was 13 days(12-14 days).At the latest follow-up,all patients remained symptom-free and had normal renal function without evidence of recurrence,and they were delighted for a hidden transumbilical scar.Conclusion:Transumbilical LESS-PN is a feasible and safe procedure albeit extremely technically challenging.Surgical outcomes at a median follow-up of 2 years are promising,while currently it should be reserved for highly selected patients with favorable tumor anatomy and performed by a very experienced laparoscopic surgeon.展开更多

We performed a resection of the first and second ribs and a reconstruction of the chest wall. A thoracotomy was performed at the anterolateral second intercostal space. The second rib cartilage was divided at the left parasternum. Based on a transmanubrial osteomuscular sparing approach, the left-upper part of the sternum and the first rib cartilage were both cut at the left clavicular-sternum joint. The posterior parts of the two ribs involving the tumor were resected at the transverse process of the vertebral bone by tearing off the anterior, middle, and posterior scalene muscles, subclavicular artery and vein. The defect size of the thorax was 15 × 9 cm, which was reconstructed by covering with a polytetrafluoroethylene dual mesh (Dual mesh, Gore tex, 2 mm). The major pectoral muscle flap was used to cover the mesh. The postoperative pathological examination diagnosed a poorly differentiated fibrosarcoma. Eventually, she had palliative therapy for the postoperative metastatic chest wall. She died 14 months after the operation.展开更多

文摘Objective:Nephron-sparing surgery(NSS) for small renal masses offers a similar functional and oncological outcome to that of radical surgery.Laparoendoscopic single-site surgery(LESS) emerges as an advanced alternative for reduced invasiveness and improves cosmesis;LESS is developing quickly and its indications have been expanded,but still in its infancy.The aim of this paper is to report our preliminary experience in transumbilical LESS partial nephrectomy(LESS-PN),so as to assess its utility, safety and efficacy.Methods:From August 2009 to October 2010,3 patients underwent transumbilical LESS-PN via a novel multi-channel TriPort by a single experienced urologist in our institution.Patient demographics,perioperative and follow-up data were prospectively collected and analyzed.Results:All the three procedures were successfully completed.A 5-mm ancillary trocar was utilized in all 3 cases.The mean operative duration was 226.3(210-254 min) with an estimated blood loss of 56.7 ml (20-100 ml).Mean warm ischemia time was 35.7 min(19-48 min).One patient was transfused due to postoperative bleeding. The recovery was uneventful and mean length of postoperative stay was 13 days(12-14 days).At the latest follow-up,all patients remained symptom-free and had normal renal function without evidence of recurrence,and they were delighted for a hidden transumbilical scar.Conclusion:Transumbilical LESS-PN is a feasible and safe procedure albeit extremely technically challenging.Surgical outcomes at a median follow-up of 2 years are promising,while currently it should be reserved for highly selected patients with favorable tumor anatomy and performed by a very experienced laparoscopic surgeon.

文摘Background:There are no clearly defined indications for pancreas-preserving duodenectomy.The present study aimed to analyze postoperative morbidity and the outcomes of patients undergoing pancreaspreserving duodenectomy.Methods:Patients undergoing pancreas-preserving duodenectomy from April 2008 to May 2020 were included.We divided the series according to indication:scenario 1,primary duodenal tumors;scenario 2,tumors of another origin with duodenal involvement;and scenario 3,emergency duodenectomy.Results:We included 35 patients.Total duodenectomy was performed in 1 patient of adenomatous duodenal polyposis,limited duodenectomy in 7,and third+fourth duodenal portion resection in 27.The indications for scenario 1 were gastrointestinal stromal tumor(n=13),adenocarcinoma(n=4),neuroendocrine tumor(n=3),duodenal adenoma(n=1),and adenomatous duodenal polyposis(n=1);scenario 2:retroperitoneal desmoid tumor(n=2),recurrence of liposarcoma(n=2),retroperitoneal paraganglioma(n=1),neuroendocrine tumor in pancreatic uncinate process(n=1),and duodenal infiltration due to metastatic adenopathies of a germinal tumor with digestive hemorrhage(n=1);and scenario 3:aortoenteric fistula(n=3),duodenal trauma(n=1),erosive duodenitis(n=1),and biliopancreatic limb ischemia(n=1).Severe complications(Clavien-Dindo≥IIIb)developed in 14%(5/35),and postoperative mortality was 3%(1/35).Conclusions:Pancreas-preserving duodenectomy is useful in the management of primary duodenal tumors,and is a technical option for some tumors with duodenal infiltration or in emergency interventions.
文摘“Spare parts surgery” is well-described in the plastic surgery literature. In the setting of trauma, otherwise discarded parts can be utilized for reconstruction resulting in a superior functional and aesthetic outcome for the patient. We describe the use of spare part surgery in order to preserve a functional knee articulation in a patient undergoing amputation for compartment.
文摘A 64-year-old female had noticed an 11 × 6 cm mass growing on her left first rib. We performed a resection of the first and second ribs and a reconstruction of the chest wall. A thoracotomy was performed at the anterolateral second intercostal space. The second rib cartilage was divided at the left parasternum. Based on a transmanubrial osteomuscular sparing approach, the left-upper part of the sternum and the first rib cartilage were both cut at the left clavicular-sternum joint. The posterior parts of the two ribs involving the tumor were resected at the transverse process of the vertebral bone by tearing off the anterior, middle, and posterior scalene muscles, subclavicular artery and vein. The defect size of the thorax was 15 × 9 cm, which was reconstructed by covering with a polytetrafluoroethylene dual mesh (Dual mesh, Gore tex, 2 mm). The major pectoral muscle flap was used to cover the mesh. The postoperative pathological examination diagnosed a poorly differentiated fibrosarcoma. Eventually, she had palliative therapy for the postoperative metastatic chest wall. She died 14 months after the operation.
