Functionally tailored transcortical approach of deep-seated lesions: An alternative to the transulcal approach? A technical case report

It is commonly believed that sulci offer a natural path to reach deep-seated lesions. However, it has also been argued that this approach carries a risk of damaging the vessels during the opening of the sulcus. We therefore were prompted to test the possibility of finding a transcortical path identified as non-functional by intraoperative brain mapping. A successful resection is presented of a left posterior isthmus clear cell ependymoma through a selected corridor based on functional mapping in an awake patient. MRI performed at 12 months showed no tumour recurrence. Pre- and postoperative extensive testing confirmed an improvement of the patient's cognitive functions. Therefore, we were able to demonstrate the feasibility of a functionally tailored transcortical approach as an alternative to the transulcal approach for deep-seated lesions. This concept should be validated in a larger patient series.

Percutaneous suprapubic cystolithotripsy approach: for whom? Why?

BACKGROUND AND PURPOSE: To evaluate the success and complications of percutaneous suprapubic cystolithotripsy (PCCL) in pediatric and adult patients with neurogenic bladder. PATIENTS AND METHODS: Between 2000 and 2004, 72 patients, all male (30 children aged 2 to 7 years [mean 4.7 years] and 42 spastic paraplegic adults aged 34 to 62 years [mean 53 years]), with sterile urine underwent PCCL under general anesthesia in one sitting. An 18-gauge needle, Amplatz dilatation set, 30F Amplatz sheath, rigid nephroscope, lithotripter (pneumatic, mechanic), and stone forceps were used. Fluoroscopy was not. A suprapubic catheter was placed in the first two patients only. RESULTS: The dimensions of the stones were on average 3.2 cm (range 1-5 cm) for the pediatric patients and 5.5 cm (4-10 cm) for the adult patients. The operating time was 20 minutes (10-35 minutes). In all cases, the stones were taken out. No serious intraoperative or postoperative complications were observed. In all cases, the transurethral catheter was removed on postoperative day 5. No recurrence was observed during the follow-up period (mean 20 months). CONCLUSION: As urethral diameters are narrow in pediatric patients and adult spastic paraplegic patients in whom an endoscopic approach could not be performed, PCCL is a safe alternative with low morbidity and complication rate. The technique is also more advantageous than open surgery with regard to cosmetic outcome and length of the hospital stay.     

Duodenopancreatectomy: Open or minimally invasive approach?

BackgroundMinimally invasive pancreaticoduodenectomy (MIPD) is a complex procedure, offered to selected patients at institutions highly experienced with the procedure. It is still not clear if this approach may enhance patient recovery and reduce postoperative complications comparing to open pancreaticoduodenectomy (OPD), as demonstrated for other abdominal procedures.MethodsA systematic literature review was conducted to identify studies comparing MIPD and OPD. Perioperative outcomes (e.g., morbidity and mortality, pancreatic fistula rates, blood loss) constituted the study end points. Metaanalyses were performed using a random-effects model.ResultsFor the metaanalysis, 8 studies including 204 patients undergoing MIPD and 419 patients undergoing OPD were considered suitable. The patients in the two groups were similar with respect to age, sex and histological diagnosis, and different with respect to tumor size, rate of pylorus preservation, and type of pancreatic anastomosis. There were no statistically significant differences between MIPD and OPD regarding development of delayed gastric emptying (DGE), pancreatic fistula, wound infection, or rates of reoperation and overall mortality. MIDP resulted in lower post-operative complication rates, less intra-operative blood loss, shorter hospital stays, lower blood transfusion rates, higher numbers of harvested lymph nodes, and improved negative margin status rates. However, MIPD was associated with longer operating times when compared to OPD.ConclusionsThe MIPD procedure is feasible, safe, and effective in selected patients. MIPD may have some potential advantages over OPD, and should be performed and further developed by use in selected patients at highly experienced medical centers.

Mediastinal goitres: when the transthoracic approach?

The correct surgical approach to mediastinal goitre is not always well defined. We reviewed why and when our patients required a transthoracic approach. From 1979 to 1998, on 7.480 patients who underwent thyroid surgery in our hospital, 374 (5%) had a goitre whose greater bulk was inferior to the thoracic inlet; 43 patients of these last ones (11%) required a transthoracic approach. General anaesthesia was performed in all patients and orotracheal intubation was selective in 11 cases (double lumen tube of Carlens). In 34 cases, the first approach was a cervicotomy, followed by sternotomy in 23 cases or right posterolateral thoracotomy in 11 cases. Three patients underwent a sternotomy and 6 a thoracotomy only. We had neither perioperative mortality nor major complications. The mean hospital stay was 5 days. Mean goitre weight was 430 g and on average the greater diameter was 13 centimetres. The removal of a substernal goitre can be difficult and risky via the cervicotomy only. A transthoracic approach is often required in the case of greater secondary, primary and recurrent mediastinal goitres.     

Outcomes for Ladd's procedure: Does approach matter?

BackgroundLaparoscopic Ladd's procedure has been proven safe and effective for the treatment of malrotation. However, the nationwide utilization and outcomes of elective Ladd's procedure are largely unknown.MethodsThe Nationwide Readmissions Database from 2010 to 2014 was used to identify patients 0–18 years (excluding newborns) with malrotation who underwent elective Ladd's procedure. Demographics, hospital factors, and outcomes were compared by approach (laparoscopic vs. open) using standard statistical tests and propensity score (PS) matched analysis. Results were weighted for national estimates.Results1343 patients (44% male) underwent elective Ladd's procedure via laparoscopic (22%) or open (78%) approach. Laparoscopic approach was more common in large hospitals (26% vs. 16%), patients >13 years (30% vs. 20%), and those with higher income (29% vs. 16%), all p < 0.001. Following PS matching, compared to the laparoscopic approach, open Ladd's was associated with index hospital length of stay > 7 days (20% vs. 8%), more post-operative gastrointestinal dysfunction (12% vs. < 1%), and more nausea, vomiting, and/or diarrhea (16% vs. 6%), all p < 0.001. The overall readmission rates within 30 days and the year of index operation were 8% and 15%, respectively. In the matched cohort, those undergoing laparoscopic Ladd's were less likely to be readmitted than those with the open approach (7% vs. 16%, p < 0.001) and experienced less gastrointestinal issues on readmission (5% vs. 15%, p = 0.002). There were similar rates of post-operative small bowel obstruction (< 3% vs. < 3%, p = 0.840) and volvulus (0% vs. < 1%, p = 0.136). Redo Ladd's procedure was performed in less than 4% of readmissions and all occurred within 5 days of initial hospital discharge.ConclusionThe majority of Ladd's procedures in the U.S. are being performed open, despite comparable outcomes following a laparoscopic approach. Readmission rates are similar with either approach, and the rate of redo Ladd's procedure is lower than previously reported.Level of evidenceLevel III.     

Hallux rigidus: How do I approach it?

Hallux rigidus is a degenerative disease of the first metatarsalphalangeal(MTP) joint and affects 2.5% of people over age 50. Dorsal osteophytes and narrowed joint space leads to debilitating pain and limited range of motion. Altered gait mechanics often ensued as 119% of the body force transmit through the 1~(st) MTP joint during gait cycle. Precise etiology remains under debate with trauma being often cited in the literature. Hallux valgus interphalangeus, female gender, inflammatory and metabolic conditions have all been identified as associative factors. Clinical symptoms, physical exam and radiographic evidence are important in assessing and grading the disease. Non-operative managements including nonsteroidal antiinflammatory drugs, intraarticular injections, shoe modification, activity modification and physical therapy, should always be attempted for all hallux rigidus patients. The goal of surgery is to relieve pain, maintain stability of the first MTP joint, and improve function and quality of life. Operative treatments can be divided into joint-sparing vs joint-sacrificing. Cheilectomy and moberg osteotomy are examples of joint-sparing techniques that have demonstrated great success in early stages of hallux rigidus. Arthrodesis is a joint-sacrificing procedure that has been the gold standard for advanced hallux rigidus. Other newer procedures such as implant arthroplasty, interpositional arthroplasty and arthroscopy, have demonstrated promising early patient outcomes. However, future studies are still needed to validate its long-term efficacy and safety. The choice of procedure should be based on the condition of the joint, patient's goal and expectations, and surgeon's experience with the technique.
