Curettage of benign bone tumors and tumor like lesions: A retrospective analysis

Background:

Curettage is one of the most common treatment options for benign lytic bone tumors and tumor like lesions. The resultant defect is usually filled. We report our outcome curettage of benign bone tumors and tumor like lesions without filling the cavity.

Materials and Methods:

We retrospectively studied 42 patients (28 males and 14 females) with benign bone tumors who had undergone curettage without grafting or filling of the defect by any other bone graft substitute. The age of the patients ranged from 14 to 66 years. The most common histological diagnosis was that of giant cell tumor followed by simple bone cyst, aneurysamal bone cyst, enchondroma, fibrous dysplasia, chondromyxoid fibroma, and chondroblastoma and giant cell reparative granuloma. Of the 15 giant cell tumors, 4 were radiographic grade 1 lesions, 8 were grade 2 and 3 grade 3. The mean maximum diameter of the cysts was 5.1 (range 1.1-9 cm) cm and the mean volume of the lesions was 34.89 cm³ (range 0.94-194.52 cm³). The plain radiographs of the part before and after curettage were reviewed to establish the size of the initial defect and the rate of reconstitution, filling and remodeling of the bone defect. Patients were reviewed every 3 monthly for a minimum period of 2 years.

Results:

Most of the bone defects completely reconstituted to a normal appearance while the rest filled partially. Two patients had preoperative and three had postoperative fractures. All the fractures healed uneventfully. Local recurrence occurred in three patients with giant cell tumor who were then reoperated. All other patients had unrestricted activities of daily living after surgery. The rate of bone reconstitution, risk of subsequent fracture or the incidence of complications was related to the size of the cyst/tumor at diagnosis. The benign cystic bone lesions with volume greater than approximately 70 cm³ were found to have higher incidence of complications.

Conclusion:

This study demonstrates the natural healing ability of bone without filling with bone grafts or bone graft substitutes. In selected sizes and locations of the benign lytic tumors and tumor like lesions extended curettage alone can be sufficient.     

Laparoscopic resection for benign tumors of the stomach.

BACKGROUND: Of all gastric tumors, less than 5% are benign. The traditional treatment of symptomatic and some asymptomatic benign tumors has ranged from mucosal resection to limited gastrectomy. Since the advent of laparoscopy, many different laparoscopic approaches to resection of benign gastric tumors have now been described in the literature. METHODS: We reviewed our experience with laparoscopic approaches to surgical resection of 7 benign gastric tumors. The tumor locations were the body (posterior wall), 3 cases; body (anterior wall), 1 case; lesser curvature, 1 case; fundus, 1 case, and antrum, 1 case. Laparoscopic wedge resection was done in 6 cases. The seventh patient underwent a Billroth I procedure because he had leiomyoma at the antrum. There was no conversion to laparotomy. RESULTS: The mean operative time was 105+/-15 minutes, and mean blood loss was 50+/-15 mL. The mean length of hospital stay was 5 days. There were no complications or mortalities. Tumor size ranged from 2 cm to 6 cm in the greatest diameter. There has been no tumor recurrence with a mean follow-up of 26 months. DISCUSSION: Laparoscopic approach is slowly carving a niche for itself in the treatment of benign tumors of the stomach. The basic principles are obtaining a precise preoperative pathological diagnosis; accurate tumor localization; achievement of tumor-free margins; avoidance of spillage of stomach contents, careful dissection of tumors in the esophagogastric junction, and preventing tumor seeding. CONCLUSION: Based on ours and other studies, laparoscopic resection of benign gastric tumors is safe and feasible.     

Pandora's box and retrorectal tumors in laparoscopy: A case report and review of the literature

INTRODUCTION

Retrorectal tumors are uncommon and the etiology diverse. Literature to define the preoperative diagnosis and plan the intraoperative management are uncommon.

PRESENTATION OF CASE

We describe a case of a 44 year old patient with a laparoscopic approach for the removal of a retrorectal tumor and emphasize on the preoperative diagnostics and the intraoperative, minimal invasive approach.

DISCUSSION

Especially because these tumors are rare and often an incidental finding in gynecologic surgery, it is important to know the various differential diagnoses and its consequences with the laparoscopic approach.

CONCLUSION

We suggest the laparoscopic approach in cases of retroperitoneal cysts of unknown origin is ideal also because anatomic structures, mostly nerves, can be easily spared.     

Robot-assisted laparoscopic repair of perineal hernia after abdominoperineal resection: A case report and review of the literature

IntroductionPerineal hernia is a protrusion of the pelvic floor containing intra-abdominal viscera. The occurrence of postoperative perineal hernia after abdominoperineal resection (APR) is rare, but reports have indicated a recent increase in occurrence following surgical treatment for rectal cancer. This has been attributed to a shift towards extralevator abdominoperineal resection, together with more frequent and long-term use of neoadjuvant therapy.Presentation of caseHere, we report the case of a patient who underwent APR for cancer. Twenty months postoperative, a perineal hernia was detected. The patient was electively scheduled for surgery. Robot-assisted laparoscopy was performed using the da Vinci Surgical System. The perineal hernia was repaired by primary closure with the placement of Symbotex Composite mesh as reinforcement for the pelvic floor. The surgery was performed without any adverse events, and the patient was discharged the day after surgery. Clinical follow-up proceeded at the designated time intervals without difficulties.DiscussionRecurrence rates of perineal hernia remain high, and surgeons face numerous challenges related to poor view, suturing and mesh placement in the deep pelvis. Numerous approaches have been described, but there is still no consensus as to the optimal repair technique for perineal hernia.ConclusionSymptomatic perineal hernias can feasibly be repaired with robot-assisted laparoscopy. Furthermore, suturing and mesh placement require less effort with the robot approach when compared to the open and laparoscopic approaches. These promising findings are demonstrated in the included video.     

Double synchronous occluding tumors of the large bowel: A report of three cases

The development of acute large bowel obstruction secondary to colorectal cancer is very common and, while right hemicolectomy with a primary anastomosis is the accepted procedure for right-sided obstructing tumors, the different strategies performed for left-sided tumors, including staged procedures, Hartmann's procedure, and resection with anastomosis, remain a subject of controversy. We present herein the case reports of three patients who developed two synchronous occlusive tumors of the large bowel. Complete exploration of the entire colon is highly recommended to assess the most feasible therapeutic option in such cases, as the second occlusive tumor, often hidden within the bowel segments, can cause failure of limited resection or intestinal decompression.     

Combined Pancreatic Islet–Lung Transplantation: A Novel Approach to the Treatment of End‐Stage Cystic Fibrosis

Patients with end‐stage cystic fibrosis (CF) and severe CF‐related diabetes (CFRD) may benefit from combined lung‐pancreatic islet transplantation. In the present study, we report the long‐term follow‐up of four end‐stage CF patients treated with combined bilateral lung and pancreatic islet transplantation from the same donor. All patients were C‐peptide negative (<0.5 μg/L) and inadequately controlled despite intensive insulin treatment. One patient was transplanted with 4 019 ± 490 islet equivalent/kg injected into the transverse colic vein using a surgical approach. In the remaining three patients, islets were cultured for 3–6 days and transplanted by percutaneous transhepatic catheterization of the portal vein. In all patients, islet allograft recovery was recognized by elevation in the plasma level of C‐peptide (>0.5 μg/L). At 6 months after transplantation, one patient showed multiple episodes of acute lung transplant rejection and a progressive decline in pancreatic islet cell function. Three out of four patients experienced an improved control of glucose levels with a HbA1c of 5.2%, 7% and 6% respectively at 1.5, 2 and 15 years follow‐up. Compared with the pretransplant period, there was a 50% reduction in mean daily insulin needs. Pulmonary function remained satisfactory in all patients. In conclusion, our cases series shows that combined bilateral lung and pancreatic islet transplantation may be a viable therapeutic option for patients with end‐stage CF and CFRD.     

Epithelial tumors of the lacrimal gland: Clinico-pathologic correlation and management

Between 1960 and 1987 29 patients underwent surgery at the Munich University Eye Hospital for benign and malignant tumors of the lacrimal gland. Fifteen tumors were classified as pleomorphic adenomas (three of them with malignant transformation), nine as adenoid cystic carcinomas, two as adenocarcinomas, two as oxyphilic adenomas, and one as oxyphilic adenocarcinoma. The clinico-pathologic correlation of these tumors is described. All age groups were involved in both benign and malignant epithelial gland tumors. A fast growing lesion with bone destruction of the lacrimal fossa in association with pain was found to be highly suspicious of a malignant epithelial tumor. Prior to surgery, inflammatory lesions and lymphomas should be ruled out by clinical history, examination, diagnostic imaging techniques, and, occasionally, by a short course of oral corticosteroids. A diagnostic biopsy prior to tumor excision and a transfrontal surgical approach via craniotomy has a negative impact on the prognosis. Thus it is mandatory to remove epithelial lacrimal gland tumors completely at the time of the initial surgical procedure. Craniotomies facilitate recurrences of lacrimal gland tumors by infiltration into the central nervous system. Lateral orbitotomies using the Krönlein technique are the best surgical approach for successful removal of these unusual tumors.     

Trans-perineal minimally invasive approach during extralevator abdominoperineal excision for advanced low rectal cancer: A retrospective cohort study

BackgroundThis study is to evaluate trans-perineal minimally invasive approach for extralevator abdominoperineal excision (TP-ELAPE) in a synchronous lithotomy position for locally advanced low rectal cancer.MethodsBetween May 2013 and February 2016, 14 patients with locally advanced low rectal cancer underwent TP-ELAPE for the perineal phase of extralevator abdominoperineal excision, and 18 patients underwent conventional ELAPE.ResultsThere was no positive circumferential resection margin in both groups. Patients who received TP-ELAPE had similar bowel perforation rate (7.1% vs. 5.6%, p = 1.000), longer transperineal operative time (100 vs. 40 min, p < 0.001) and higher surgical difficulty visual analog scale (VAS) scores (6 vs. 2, p < 0.001), while had shorter total procedure time (215 vs. 260 min, p = 0.015), lower VAS pain scores on day 1 postoperatively (5 vs. 6.5, p = 0.049), shorter postoperative anus exhausting time (22 h vs 28 h, p = 0.006), and shorter postoperative hospital stay (11.5 d vs 13.5d, p = 0.028) compared with patients who received conventional ELAPE. There was no local recurrence with median follow-up time of 53 months in the TP-ELAPE group and 51 months in the conventional ELAPE group. There were no differences for disease-free survival (p = 0.835) and overall survival (p = 0.829) between groups.ConclusionsTP-ELAPE approach in the synchronous lithotomy position might be a feasible approach for low rectal cancer, while ensuring a radical and safe surgical procedure.     

Double-segment total vertebrectomy for the surgical treatment of congenital kyphoscoliosis: a case report

BACKGROUND CONTEXT: Congenital kyphosis or kyphoscoliosis is an uncommon deformity that usually is progressive without surgical intervention. In the lately diagnosed or neglected cases of congenital kyphoscoliosis, the patients may come with shoulder-trunk imbalance anomalies, severe deformity in coronal and sagittal plane, rib cage deformities, pelvic tilt, presence of intramedullary anomalies, neurological deficit, and difficulty in walking and cardiopulmonary problems. PURPOSE: To present a technical note related with double-segment total vertebrectomy for the surgical treatment of a patient who had neglected congenital kyphoscoliosis in lumbar spine. STUDY DESIGN: Case report. METHODS: A 19-year-old girl had submitted to our center with complaints of deformity and pain in her back. Her physical examination revealed scoliosis and gibbosity in lumbar region. Her neurological examination was normal. In the radiological examination, X-ray films showed 42 degrees lumbar scoliosis in frontal plane and 35 degrees kyphotic curvature in the sagittal plane. RESULTS: Three-staged (posterior-anterior-posterior) surgery in the same session (same anesthesia) was performed. CONCLUSION: Total or partial vertebrectomy on the apex of the deformity and the adjacent vertebral bodies along with anterior stabilization by means of a cylindrical cage combined in one operative procedure preceded by temporary posterior instrumentation and followed by posterior instrumentation and fusion may be preferred for the treatment of congenital kyphoscoliosis in neglected cases to provide spinal cord decompression.     

Solid and cystic tumors of the pancreas: A report of two cases

Two patients operated on for solid and cystic tumors of the pancreas are presented. One of them had a history of a benign cerebral tumor (astrocytoma) for which a ventriculo-peritoneal shunt had been done 3 years previously. The operations performed were a type-I regional pancreatectomy in one patient and a Whipple's procedure in the other. The patients were discharged well without complications and no recurrence has been detected 1 year after the operation     

Malignant phyllodes tumors of the breast: A comprehensive literature review

Malignant phyllodes tumors (MPT) have always been a great deal of controversy among fibroepithelial tumors of the breast. Genetics, histopathology, and tumor behavior on the cellular scale shape their extent of aggressiveness. Diagnosis is based on radiological and pathological findings. Cure is surgical excision. This article reveals the most common clinical indices, which should raise the surgeon's concerns on a benign‐looking tumor to further investigate its nature, and the importance of an adequate surgical intervention, preferably done by an oncoplastic breast surgeon, in order to accomplish the ideal outcome for the patient.     

Need of the hour: Structural heart intervention training for trainee surgeons in India

Cardiothoracic surgery is on the verge of undergoing a major metamorphosis from being a conventional surgical branch to a technologically powered specialty with plenty of emphasis on learning the minimally invasive techniques, and a step forward is the advent of interventional techniques to treat most of the major cardiac ailments. Though the world of interventions has been traditionally dominated by the physicians, it is time we surgeons get ourselves actively involved in learning and performing these interventional procedures to stay relevant. This is not an attempt to disrupt the physician-surgeon harmony but to nurture a symbiotic relationship between the two specialties for advancement in cardiac science and technological growth, ultimately to benefit the patient. In this article, we discuss the Indian and the global scenario of the role of surgeons in the interventional arena and various training modalities available for surgeons to learn the art of cardiac interventions. We tried to understand the impediments in implementing interventional training for surgeons and also propose certain amendments to the way the future cardiothoracic surgeons are trained.     

Surgical practices for urological tumors: A nation-wide survey in Japan in 2005

Objective:   To clarify how popularly the minimally invasive surgeries for urological tumors are currently conducted in Japan and to predict future trends.
Methods:   A nation-wide survey was performed by the Japanese Association for Minimum-Incision Endoscopic Surgery under the support of the Japanese Urological Association (JUA). A questionnaire was sent to 1186 JUA-certified educational institutions asking about surgical practices for representative urological tumors performed in 2005 and those to be performed in the near future. Surgical modalities were categorized into open, laparoscopic and minimized-incision surgeries, defined as that the operator considers the incision to be minimal and including minimum-incision endoscopic surgery but not limited.
Results:   506 of the 1186 institutions (43%) responded and 20 193 surgical procedures were reported with radical prostatectomy being most frequently performed. Overall 20% and 6% of the procedures were performed with laparoscopic and minimized-incision surgeries, respectively. More than 20% of the respondents performed open surgery with reduced incision size than before. Surgical procedures without inserting fingers or hand were reported in 5–11% of the open surgeries and 33–45% of the minimized-incision surgeries. Endoscopy was utilized in 4–14% of the open surgeries and 24–59% of the minimized-incision surgeries. There was no difference in the incidence of complications among the surgical modalities. 40% and 27% of the respondents are aiming at laparoscopic surgery and at minimized-incision surgery, respectively.
Conclusions:   The results of this nation-wide survey indicate that minimally invasive surgeries, currently performed in 26% of urological tumor surgeries, are aimed at by the majority of the survey respondents.     

Endoscope-assisted microsurgery for tumors of the septum pellucidum: surgical considerations and benefits of the method in the treatment of four serial cases

Neoplasms that primarily originate from the septum pellucidum are extremely rare. Generally the septum pellucidum is involved in direct extension of tumors that arise from the neighboring structures, principally the corpus callosum. Endoscope-assisted techniques form a useful adjunct to common microsurgical procedures to completely remove intraventricular lesions. There are two main advantages of endoscope-assisted surgery over common microsurgical techniques: reduction of superficial brain retraction with less iatrogenic trauma to the neighboring structures and inspection of hidden corners depict simultaneously anatomical details which are not precisely visible in the zoomed and thus light-reduced beam of the microscope. Four patients with septum pellucidum tumors underwent surgery by a transcallosal approach. In all four patients the endoscope-assisted microsurgery technique was used to remove the tumor. In one of the four patients neuronavigation was additionally used for guidance. Complete tumor excision was achieved in all patients. The histological findings showed pilocytic astrocytoma in two cases, one subependymoma and one neurocytoma, respectively. There were no postoperative complications. Endoscope-assisted microsurgery provides maximum efficiency to remove the septum pellucidum tumors with minimum invasiveness.
