Distal hypospadias: which repair?

OBJECTIVE: To compare the function, complications and cosmesis after a modified Thiersch-Duplay and Mathieu unstented urethroplasty. PATIENTS AND METHODS: Over a 5-year period 381 consecutive patients (not randomized) with distal hypospadias were evaluated. A modified Thiersch-Duplay with dorsal incised urethral plate tubularization (group A) was undertaken in 170 (45%) and a parameatal based flip-flap Mathieu hypospadias repair (group B) in 211 (55%). No urinary diversion or stent was used in any of the 381 patients. RESULTS: In both groups the mean (sd) follow-up was 3.1 (1.4) years. All 381 patients voided spontaneously after surgery and none developed urinary retention needing catheterization. In groups A and B, respectively, the overall late complications were 12 (7.1%) and 32 (15.2%) (P=0.001), with urethrocutaneous fistula in six (3.5%) and 26 (12.3%; P=0.001); secondary surgery for fistula repair was successful in all boys in A and 89% in B. The glanular meatus was a vertical slit in all in group A and 86% in B (P=0.02). In both groups, 71% of the children who are now toilet-trained and standing to void have a good calibre, single and straight urinary stream in a forward direction. CONCLUSIONS: Stenting or urinary diversion is unnecessary after distal hypospadias surgery. The functional results were good in those standing to void. A more natural vertical slit-like glanular meatus was easily created using the modified Thiersch-Duplay urethroplasty, with a lower fistula rate.     

Distal radial fractures Operative versus nonoperative treatment

There is some evidence to suggest superior results of surgical treatment that includes open reductioninternal fixation (ORIF) or percutaneous pin fixation (not including Kapandji pinning) to stabilize fracture fragments and improve functional ability compared with conservative treatment. However, larger studies with longer follow-up are needed to verify these results.     

Is Preservation of the Remnant Stomach Safe During Distal Pancreatectomy in Patients Who Have Undergone Distal Gastrectomy?

Background

Whether the remnant stomach can be safely preserved when performing distal pancreatectomy (DP) in patients with a prior distal gastrectomy (DG) remains unclear because the remnant stomach and pancreatic body/tail share an arterial blood supply via the splenic artery (SPA).

Methods

A total of 18 patients with prior DG who underwent DP were enrolled in this study. Clinicopathologic data were retrospectively analyzed with a focus on management of the remnant stomach and complications related to ischemia of the remnant stomach. Additionally, intraoperative indocyanine green (ICG) fluorescence angiography was performed to visualize the blood flow and circulation in the remnant stomach.

Results

Ten patients underwent a standard DP (DP in conjunction with splenectomy and division of the SPA) with preservation of the remnant stomach. The entire stomach was preserved in seven patients, and three underwent concomitant partial resection of the remnant stomach. No patients in whom the entire remnant stomach was preserved developed postoperative complications associated with it, whereas two of the three patients who underwent partial resection of the remnant stomach developed severe ischemic complications. Intraoperative ICG fluorescence angiography revealed a caudally directed circulation of blood from the esophagogastric junction through the intramural capillary network in the remnant stomach.

Conclusions

When performing DP in patients with a prior DG, preservation of the entire remnant stomach was a safe procedure because of the presence of an intramural network that supplies blood to the remnant stomach. In contrast, partial resection of the remnant stomach could be dangerous because of the potential for severe ischemic complications.     

Is Therapy Necessary After Distal Biceps Tendon Repair?

The EndoButton technique of distal biceps tendon repair provides strong biomechanical fixation. This strength of fixation may allow earlier postoperative range of motion (ROM). A retrospective review of 15 male patients undergoing single incision EndoButton repairs was used. Six subjects participated in conventional supervised postoperative rehabilitation while nine subjects were allowed unrestricted ROM after 2 weeks. Final ROM, time to full ROM, and Disabilities of Arm Shoulder and Hand (DASH) scores were compared. There was a significant difference for time to full ROM (p < 0.05). The mean time to full ROM was 8.67 weeks for the supervised therapy group and 4.38 weeks for the unrestricted group. There were no reruptures in either group. There were no significant differences in final ROM or DASH scores. These data suggest that unrestricted ROM results in a quicker return to full ROM without an increased risk of rerupture.     

Laparoscopic Left Nephrectomy with “En Bloc” Distal Splenopancreatectomy

Background  

Multiorgan resection for cancer is considered a demanding laparoscopic procedure. We report a laparoscopic radical nephrectomy and distal splenopancreatectomy for a locally advanced kidney tumor.     

Intra-articular Distal Radius Fractures: The Role of Arthroscopy?

Arthroscopic assisted fixation of distal radius fractures offers several advantages. It allows for the evaluation of the articular reduction under a bright light and magnification. Particularly, rotation of the fracture fragments, which is difficult to judge under fluoroscopy, may be detected arthroscopically and corrected. Washing out fracture hematoma and debris potentially allows for improved range of motion, as shown by the studies of Doi and Stewart. Wrist arthroscopy also allows for detection and management of associated soft tissue injuries, which has been shown to occur with distal radius fractures. Some of the more severe interosseous ligament injuries can be diagnosed on plain or traction radiographs. Arthroscopy performed at the same time as fracture reduction, however, substantially increases the recognition of these injuries. In addition, it is wellknown that the management of acute interosseous ligament tears has a better prognosis when compared with chronic lesions.     

Where to Tenodese the Biceps: Proximal or Distal?

Background  

The best location for biceps tenodesis is controversial as surgeons have begun to question whether tenodesis location affects the incidence of residual bicipital postoperative pain. An open distal tenodesis technique has been previously proposed to eliminate remaining symptoms at the bicipital groove.

Distal Femoral Osteotomy: Is Internal Fixation Better than External?

Background  

Distal femoral osteotomies (DFO) can be used to correct deformities around the knee. Although osteotomies can be fixed with either internal or external fixation techniques, the advantages of one over the other are unclear.     

Ureteroscopic Stone Removal in the Distal Ureter. Why Change?

Purpose

We compared our experience with ureteroscopic stone basket manipulation under fluoroscopic guidance to ultrasound ureterolithotripsy for distal ureteral stone removal.

Materials and Methods

Retrospectively, we analyzed the medical records of 981 patients with ureteral calculi between January 1994 and December 1995, of whom 483 (49%) were treated for stones in the lower ureter and constituted our study group. The decision of when to perform lithotripsy (group 2) versus a basket procedure (group 1) was based on a prospective nonrandomized study and both groups were compared historically. All 322 patients in group 1 (mean age 49 years, range 14 to 86) primarily underwent ureteroscopic stone basket manipulation using the 4-wire Segura* basket. If the calculus could not be removed with the basket and another procedure was necessary, the case was considered a failure. The 161 patients in group 2 (mean age 37 years, range 14 to 74) underwent initially ultrasound ureterolithotripsy for stone fragmentation followed or not by removal of the fragments with the basket. Stone size did not differ significantly between groups 1 (mean 0.9 cm., range 0.6 to 1.7) and 2 (mean 0.8 cm., range 0.7 to 2.0). Ureteroscopy was performed in both groups with epidural anesthesia and on an outpatient basis in the majority of cases.*Van-tec, Spencer, Indiana.

Results

The stone-free rate after 1 procedure was 98.1 and 95.6% in groups 1 and 2, respectively. For group 2 versus group 1 the operative time was longer (mean 50, range 25 to 90 versus mean 19 minutes, range 11 to 40, respectively, p <0.001), the complication rate was greater (16.1 versus 4.3%, respectively, p <0.001) and average hospital stay was longer (2.1 versus 0.15 day, respectively, p <0.001).

Conclusions

Ureteroscopic stone treatment with basket manipulation under fluoroscopic guidance or ultrasound ureterolithotripsy provided a high stone-free rate. However, stone removal with the basket manipulation technique should be considered the first choice for treatment of small distal ureteral calculi based on the minimal morbidity, and short operative and recovery times.     

Proximal Versus Distal Gastric Carcinoma—What Are the Differences?

Background: The incidence of proximal gastric third carcinoma (PGC) has been rising in recent years. Classification and surgical therapy remain controversial.Methods: Between May 1986 and October 1997, 532 patients were operated for primary gastric carcinoma. All patient data were analyzed retrospectively comparing findings in patients with PGC and those with distal gastric carcinoma (DGC).Results: Two hundred fifty patients had a PGC, and 282 patients had a DGC. The rate of R0 resections was 79.3% for PGC and 81.6% for DGC. In 93.9% of the patients with PGC total gastrectomy was performed; for DGC total gastrectomy was done in 74.5% of patients. Postoperative morbidity and mortality were 29.2% for PGC and 23.8% for DGC, and 3.2% for PGC and 3.5% for DGC, respectively. Patients with advanced tumor stages (stage III and IV) were more common in the PGC group (73.3% vs. 53.6% in DGC). After R0 resection, the 5-year survival rate was 33.2% for PGC and 59.7% for DGC.Conclusions: There was no significant difference between the rates of R0 resections for PGC and DGC. Total gastrectomy can be performed with low postoperative morbidity and mortality. PGC and DGC represent the same tumor entity, and prognosis is similar, but due to more advanced tumor stages, the long-term survival is worse for patients with PGC than for those with DGC. Left retroperitoneal lymphadenectomy may be indicated for PGC.
