Partial cystectomy for bladder squamous cell carcinoma with a 10-year follow-up: a case report

Squamous cell carcinoma (SCC) of the bladder is a rare malignancy of the urinary system. It is prone to invasion and metastasis in the early stage and has a poor prognosis. This case reports a 65-year-old female patient with SCC of the bladder who was free of disease recurrence and metastasis 10 years after partial cystectomy (PC) combined with left ureteral reimplantation. The treatment plan and admission of this patient were retrospectively analyzed in order to provide some reference significance for the treatment plan for the SCC of the bladder.

Possible Kidney Complications after Application of Cell Technologies for the Repair of the Resected Liver

The state of rat kidneys after injection of bone marrow multipotent stromal cells (MSC) labeled with Vybrant CM-Dil into intact or resected liver was studied by fluorescence microscopy. The main structural changes in the kidneys after MSC injection into intact and partially resected liver manifested as granular dystrophy and necrobiotic/necrotic changes in single epithelial cells of the distal tubules and collecting ducts, thrombosis of some vessels, progression of an ascending urinary tract infection (detection of dust-like fluorescent objects), which can be due to the immunomodulating or even immunosuppressive influence of MSC and their detritus. MSC injected into the intact or resected liver, as well as the products of their degradation were not detected in the kidneys at all terms of observation. After injection of MSC into partially resected liver, manifestations of bacterial contamination of the renal medulla appeared later. The injection of MSC into the liver can be complicated by thrombosis of the renal vessels, which should be taken into account when using this administration route in the cell therapy.

Partial resection of native and prosthetic arteriovenous fistula as a treatment of late infections complications - series of case reports

INTRODUCTION

Infection of arteriovenous fistula (AV) used for hemodialysis (HD) is associated with massive bleeding, sepsis development, formation of metastatic infectious foci, and a high risk of AV loss. Urgent management of an infected AV is crucial for successful treatment and AV salvage.

CASE REPORTS

We present the use of partial resection as a successful method of dealing with late AV infection in two cases. In case 1, the resection was performed due to an infection of the native arteriovenous fistula (AVF) with two defects above the drainage vein aneurysms. In case 2, partial resection and replacement of the prosthetic arteriovenous fistula (AVG) were done due to an infection of HD puncture site. The AVs remained patent in both cases, with no further signs of infection postoperatively and, most importantly, without the need to use a temporary HD catheter.

CONCLUSION

The establishment of a new AV is limited by the quality of the venous and arterial systems. All surgical, interventional and non-surgical means should be used to safely maintain the created AV patent. Provided that the requirements of an early indication are met, partial resection of the AV is the method of choice for AV infections and allows us to avoid using a permanent dialysis catheter in our patients.

Endoscopic Endonasal Resection of Symptomatic Rathke Cleft Cysts: Total Resection or Partial Resection

Objective: Rathke cleft cysts (RCC) are benign sellar lesions, and endoscopic endonasal surgery (EES) for symptomatic RCC is becoming increasingly popular, but total resection or partial resection (TR or PR) of the cyst wall is still inconclusive. The aim of this study was to review the complications and clinical prognoses associated with total and partial resection of the cyst wall by EES.

Methods: We retrospectively analyzed a series of 72 patients with symptomatic RCC treated by EES from -January 2011 to June 2019 at Shenzhen University First Affiliated Hospital. For these 72 cases, 30 were treated with TR and 42 were treated with PR. Intra- and post-operative complications and clinical prognosis were investigated.

Results: All 72 patients underwent a pure EES. In the TR group, 10 patients (33.3%) had intraoperative cerebrospinal fluid leakage (CSF leak), three patients (10%) had postoperative CSF leak, eight patients (26.7%) had postoperative diabetes insipidus (DI), eight patients (26.7%) had postoperative electrolyte disturbance, and 12 patients (40%) had temporary hypopituitarism postoperatively. While in the PR group, three patients (7.1%) had intraoperative CSF leak, two patients (4.8%) had postoperative DI, three patients (7.1%) had postoperative electrolyte disturbance, four patients (9.5%) had temporary hypopituitarism postoperatively, and no cases experienced postoperative CSF leak. The intra- and post-operative complications were significantly higher in TR group then PR group (P _{IntraoperativeCSFleak} = 0.004, P _{Post−operativeCSFleak} =0.036, P _TransientDI = 0.008, P _{Temporaryhypopituitarism} = 0.002, P _{Permanenthypopituitarism} = 0.036, P _{Electrolytedisturbance} = 0.023). No significant differences in post-operative improvement and recurrence.

Conclusions: EES is a safe and effective approach for the treatment of symptomatic RCC. Complete sucking out the cyst contents and partial resection of the cyst wall may be sufficient for treatment, and total resection of the cyst wall is associated with a higher incidence of complications.

Risk of death due to other causes is lower among octogenarians with non-small cell lung cancer after wedge resection than lobectomy/segmentectomy

OBJECTIVE

We aimed to determine the influences of surgical procedures on the postoperative death of octogenarians with clinical Stage IA non-small cell lung cancer excluding cT1mi.

METHODS

We compared overall survival and the cumulative incidence of death due to all and other causes among 1 130 279, and 191 consecutive patients aged ≤79 and ≥80 years after lobectomy, segmentectomy and wedge resection at three institutions. Death due to other causes was defined as death due to any cause except non-small cell lung cancer.

RESULTS

The median followup was 53 months. The 5-year overall survival rates for patients aged ≥ 80 and ≤ 79 years after lobectomy, segmentectomy and wedge resection were respectively, 78.0% (95% confidence interval, 63.8%-87.2%) versus 91.2% (95% confidence interval, 89.0%-92.9%), 68.1% (95% confidence interval, 45.2%-83.1%) versus 90.0% (95% confidence interval, 84.6%-93.5%), and 62.7% (95% confidence interval, 44.0-76.7%) versus 84.4% (95% confidence interval, 76.3%-89.9%) (P < 0.01 for all). The cumulative incidence of death due to other causes after wedge resection was similar between patients aged ≥ 80 and ≤ 79 years (P = 0.45), but significantly higher in those aged ≥ 80, than ≤ 79 years after lobectomy or segmentectomy (P = 0.00015 and 0.00091, respectively).

CONCLUSIONS

The influence of wedge resection on death due to other causes was lower than that of lobectomy or segmentectomy in patients with non-small cell lung cancer aged ≥ 80 years. Wedge resection might be a useful option for octogenarians even if they can tolerate lobectomy/segmentectomy to avoid postoperative death due to causes other than non-small cell lung cancer.

Decannulation after cricotracheostomy: a comparison of partial cricoid cartilage resection with conventional tracheostomy

BACKGROUND

Cricotracheostomy, a modified procedure to open the airway with partial cricoid cartilage resection, was recently reported to be useful in selected cases.

AIMS/OBJECTIVES

To examine decannulation outcomes in patients who underwent cricotracheostomy by comparing it with a conventional tracheostomy.

MATERIALS AND METHODS

Data from 127 consecutive adult patients, who underwent either conventional tracheostomy or cricotracheostomy between 2016 and 2019, were collected and analyzed with respect to subsequent decannulation with stoma closure.

RESULTS

Conventional tracheostomy and cricotracheostomy were performed in 94 and 33 patients, respectively. The most frequent reason for choosing cricotracheostomy was a physiological low-lying larynx (n = 12). After excluding 30 patients who were considered ineligible due to their primary disease, subsequent decannulation with stoma closure was achieved in 35 (46%) of 76 cases with conventional tracheostomy and seven (33%) of 21 cases with cricotracheostomy, showing no significant difference (p = .33).

CONCLUSIONS/SIGNIFICANCE

Compared with a conventional tracheostomy, cricotracheostomy had an acceptable decannulation outcome. However, it should be emphasized that an appropriate selection of patients is required on considering the advantages of cricotracheostomy.

Partial Resection of Spinous Process for the Elderly Patients with Thoraco-Lumbar Kyphosis: Technical Report

Background and objectives: Global sagittal imbalance with lumbar hypo-lordosis can cause low back pain (LBP) during standing and/or walking. This condition has recently been well-known as one of the major causes of reduced health-related quality of life (HRQOL) in elderly populations. Decrease in disc space of anterior elements and an increase in the spinous process height of posterior elements may both contribute to the decrease in lordosis of the lumbar spine. To correct the sagittal imbalance, the mainstream option is still a highly invasive surgery, such as long-segment fusion with posterior wedge osteotomy. Therefore, we developed a treatment that is partial resection of several spinous processes of thoraco-lumbar spine (PRSP) and lumbar extension exercise to improve the flexibility of the spine as postoperative rehabilitation. Materials and Methods: Consecutively, seven patients with over 60 mm of sagittal vertical axis (SVA) underwent PRSP. The operation was performed with several small midline skin incisions under general anesthesia. After splitting the supraspinous ligaments, the cranial or caudal tip of the spinous process of several thoraco-lumbar spines was removed, and postoperative rehabilitation was followed to improve extension flexibility. Results: The average follow-up period was 13.0 months. The average blood loss and operation time were 11.4 mL and 47.4 min, respectively. The mean SVA improved from 119 to 93 mm but deteriorated in one case. The mean numerical rating scale of low back pain improved from 6.6 to 3.7 without any exacerbations. The mean Oswestry Disability Index score was improved from 32.4% to 19.1% in six cases, with one worsened case. Conclusions: We performed PRSP and lumbar extension exercise for the patients with LBP due to lumbar kyphosis. This minimally invasive treatment was considered to be effective in improving the symptoms of low back pain and HRQOL, especially of elderly patients with lumbar kyphosis.

An approach to grossing of hepatectomy specimens

Liver resections are performed for acute and chronic end stage liver failure, primary and secondary liver malignancies as well as for several other neoplastic and non-neoplastic conditions. Hepatectomy specimens can be total, partial, or wedge resections. These specimens are relatively rare and complex. Meticulous handling, orientation, dissection, margin assessment, and reporting as per the latest guidelines, often require a multidisciplinary approach. This article discusses the approach to grossing of hepatectomy specimens, and the most important macroscopic considerations for specific conditions.

Individual Treatment Decisions for Central Neurocytoma

Objective: Central neurocytomas (CNs) are rare, and this has resulted in a paucity of information and a lack of clarity regarding their optimal management. This study aimed to explore individual treatment strategies for CNs and the benefits of these strategies for patients.

Methods: This single-center study retrospectively analyzed data from 67 patients with CNs who underwent surgery. Based on the extent of resection, patients were divided into complete and incomplete resection groups. The patients were followed, and overall survival (OS) and progression-free survival (PFS) were determined.

Results: Of 55 patients (82.1%) who underwent complete resections, 24 received radiotherapy (24/55, 43.6%). Of 12 patients who underwent incomplete resections, 9 (9/12, 75.0%) received radiotherapy. The OS (p = 0.003) and PFS (p = 0.006) intervals were significantly longer in the complete resection group than in the incomplete resection group. Postoperative radiotherapy did not affect OS (p = 0.129) or PFS (p = 0.233) in the complete resection group. In the incomplete resection group, postoperative adjuvant radiotherapy prolonged patient survival significantly (p = 0.021). PFS was significantly longer among patients who underwent complete resection without radiotherapy than in those who underwent incomplete resection followed by radiotherapy (p = 0.034). Functional dependence on admission, which was defined as a Karnofsky Performance Status score <70, was an independent risk factor associated with long-term survival in patients with CN. Postoperative complications were not associated with the amount of tumor resected. The prognosis of patients aged ≥ 50 years was relatively poor. The atypical CN recurrence rate was relatively high (7.8%).

Conclusions: To protect function as much as possible, complete tumor resection should be the first choice of treatment for CN. After gross total resection, adjuvant radiotherapy is not acceptable. Postoperative adjuvant radiotherapy improves the prognosis of patients who have undergone incomplete tumor resections. Adjuvant radiotherapy is not recommended after complete resections of atypical CNs, and close follow-up with imaging is required. Our findings can help guide decision-making regarding the treatment of CNs and could potentially maximize the benefits of treatment for patients with CN.

Arthroscopic Partial Capitate Resection for Type Ia Avascular Necrosis: A Short-Term Outcome Analysis

PURPOSE

To examine short-term clinical results of arthroscopic partial resection for type Ia avascular necrosis of the capitate.

METHODS

Patients who underwent arthroscopic treatment for type 1a avascular necrosis of the capitate with at least 1-year follow-up were identified through a retrospective chart review. The necrotic capitate head was arthroscopically resected with removal of the lunate facet and preservation of the scaphoid and hamate facets. Wrist range of motion, grip strength, and radiographic parameters--carpal height ratio, radioscaphoid angle, and radiolunate angle-were determined before surgery and at the latest follow-up. Patients completed a visual analog scale for pain; Disabilities of the Arm, Shoulder, and Hand measure; and the Patient-Rated Wrist Evaluation score before surgery and at the latest follow-up.

RESULTS

Five patients (1 male, 4 females) with a mean age of 34 years (range, 16-49 years) and a mean follow-up duration of 20 months (range, 12-36 months) were identified during the chart review. All were type Ia (Milliez classification). Arthroscopy revealed fibrillation or softening with cartilage detachment at the lunate facet of the capitate head and an intact articular surface at the scaphoid and hamate facet. At the latest follow-up, the mean wrist flexion-extension was 123° (vs 81° before surgery) and grip strength was 74% (vs 37% before surgery). The visual analog scale score for pain; the Disabilities of the Arm, Shoulder, and Hand score; and the Patient-Rated Wrist Evaluation score before surgery showed a significant improvement following treatment. Radiographic parameters did not significantly change at the final follow-up, although the proximal carpal row trended toward flexion.

CONCLUSIONS

Arthroscopic partial resection of the capitate head was an acceptable treatment for type Ia avascular necrosis of the capitate. It provided adequate pain relief and improved the range of wrist motion and grip strength during short-term follow-up.

Posterior fossa ependymoma in childhood: 60 years event-free survival after partial resection—a case report

A 13-year-old boy with severe clinical symptoms and signs underwent surgery for a posterior fossa ependymoma in 1954. The tumor was adjacent to the floor of the fourth ventricle, and surgery was complicated by profound bleeding. Therefore, only a partial resection was performed. Postoperative radiotherapy was given to the posterior fossa. The recovery was uneventful, and he has been in full-time work until the age of 62 years and is now 74 years old. Repeated MRI scans demonstrate a stable residual fourth ventricular tumor.

Free skin flap reconstruction after partial hypopharyngectomy with laryngeal preservation

Surgical resection of hypopharyngeal cancer often affects laryngeal function. The aim of this study is to assess the reliability and efficacy of free skin flap transfer after partial hypopharyngectomy with laryngeal preservation. This study designs a retrospective analysis. The subjects were 54 patients who underwent free skin flap reconstruction immediately after partial pharyngolaryngectomy or hypopharyngectomy with laryngeal preservation. The defects were classified into four types based on the location of the hypopharyngeal defect. Functional results were evaluated by routine physical examination findings and parameters related to swallowing function and X-ray barium deglutition examination. Perioperative mortalities and morbidities were reviewed. There were no perioperative mortalities and 98% of the flaps survived. Forty-three patients (80%) were able to eat an unrestricted diet and experienced no aspiration. Restriction of the diet was significantly associated with the extent of oesophageal mucosal resection. In conclusion, free skin flap reconstruction is confirmed to be a safe and effective strategy to maintain laryngeal function and good quality-of-life.

Volumetric measurement of vestibular schwannoma tumour growth following partial resection: predictors for recurrence

Vestibular schwannomas (VS) have a higher risk of recurrence following subtotal resection than following near-total resection. We measured tumor remnant growth volumetrically in an attempt to determine potential predictors for postoperative recurrence following subtotal resection. We reviewed the charts of patients who had undergone VS surgery between 1998 and 2007. Thirty patients had an incomplete resection. The principal outcome measure was change in tumor volume (TV) on serial imaging. At a median follow-up of 6.8 years, volumetric measurements showed that 12 patients (40%) developed further tumor growth, while 18 patients remained with stable residual disease. The median rate of growth was 0.53 cm(3)/year. Two-dimensional measurements confirmed growth in only eight of these patients. The postoperative residual TV correlated significantly with subsequent tumor growth (p = 0.038). All patients with residual volumes in excess of 2.5 cm(3) exhibited recurrence. On univariate analysis, only postoperative TV was significantly associated with growth. Median time to failure was 21.5 months. This is the first report of volumetric measurements of VS tumor growth postoperatively. Volumetric measurements appear to be superior to two-dimensional measurements in documenting VS growth and patients with residual tumors >2.5 cm(3) have a significantly higher rate of recurrence.
