Comparison of Billroth I,Billroth II,and Roux-en-Y reconstructions following distal gastrectomy: A systematic review and network meta-analysis

Major surgical treatment for distal gastric cancer include Billroth I (BI), Billroth II (BII), and Roux-en-Y (RY). Since the optimal reconstruction methods remains inconclusive, we aimed to compare these treatments in terms of intraoperative and postoperative course after distal gastrectomy with a systematic review and random-effects network meta-analysis. We searched PubMed, Web of Knowledge, Ovid's database for prospective, randomized, controlled trials comparing the outcomes of BI, BII, and RY reconstruction after distal gastrectomy until January 2020. From the included studies, operative time, intraoperative blood loss, postoperative hospital stay, endoscopic findings and complications were extracted as the short- and long-term outcomes of reconstructions. The network meta-analysis was performed with R 3.5.2 software as well as “gemtc” and “forestplot” packages. Twelve randomized controlled trials (RCTs) involving 1662 patients were included. RY reconstruction has a lower risk and degree of remnant gastritis than BI and BII reconstructions(OR 0.40, 95%Crl: 0.24–0.64; OR 0.36, 95% Crl: 0.16–0.83, respectively). BI reconstruction method took significantly less time to perform as compared to BII and RY reconstruction (WMD 20, 95% Crl: 0.18–41; WMD 30, 95% Crl: 14–25, respectively). No differences in intraoperative blood loss, time to resumed oral intake, postoperative hospital stay, reflux oesophagitis and complications among the three reconstructions. The RY reconstruction after distal gastrectomy was more effective in preventing remnant gastritis than Billroth I and Billroth II reconstruction, although RY reconstruction was considered as technical complexity.     

Distal oblique osteotomy versus cheilectomy for moderate-advanced hallux rigidus: A 2-year propensity-score-matched study

BackgroundThe surgical treatment of moderate-advanced hallux rigidus is controversial. Cheilectomy is widely used but has recurrence rates of up to 30%. Dorsal oblique metatarsal osteotomy (DOO) has also shown good results, however, there is no study comparing outcomes of the DOO against cheilectomy.MethodsThis was a retrospective propensity score matched study based on registry data from a single tertiary institution. Between 2007 and 2017, all patients who had undergone dorsal cheilectomy or DOO for hallux rigidus were included. Patients with previous foot surgery, revision surgeries, and concomitant surgical procedures were excluded. Clinical outcomes, complication rates, revision rates and patient satisfaction were assessed at 2 years postoperatively.ResultsThere were 44 patients (34 cheilectomy, 10 DOO). After propensity score matching, 17 cheilectomy and all 10 DOO cases were selected for comparison. Patients in both groups had a significant improvement in visual analogue pain scores (VAS) and AOFAS 1st toe scores 2-years post-operatively (P < 0.001) with high levels of post-operative satisfaction (85.1%). Overall there were no statistically significant differences in post-operative scores, improvement in scores, complication rates, revision rates, and levels of patient satisfaction between groups.ConclusionsBoth the DOO and cheilectomy give similarly good outcomes for moderate-advanced hallux rigidus. Further studies are needed to elucidate differences in indications for each procedure.     

Extensor hallucis longus distal tenotomy for spasticity in a patient with interphalangeal joint hyperextension after stroke

BackgroundThe extension deformity of the interphalangeal (IP) joint of the hallux is a rare focal clinical entity usually detected in patients with no underlying pathology. It may be due to extensor hallucis longus (EHL) overactivity, although it has not been previously reported in patients with neurological disorders. The lesion should be differentiated from the persistent hyperextension of the great toe at the metatarsophalangeal (MTP) joint. Although MTP hyperextension of the hallux due to hypertonia of the EHL is a typical sequel of stroke, it has also been detected in a wide variety of disorders.Materials and MethodsA patient with right hemiparesis following stroke, which had an almost complete functional recovery, is presented. She was disabled by focal spasticity of the EHL, leading to persistent hyperextension of the IP joint of the hallux. The deformity appeared on the long-term follow-up, on both sides within a 3-year period. It was treated with bilateral percutaneous distal EHL tenotomy. On the left side, a percutaneous dorsal IP joint capsulotomy was additionally performed.Results and ConclusionA complete reduction of the deformity was achieved on both sides with functional rehabilitation. It is assumed that EHL hyperactivity following stroke in our patient was complicated by IP instead of MTP extension deformity, due to the coexistent flexor hallucis longus weakness. Bilateral distal EHL tenotomy, associated with percutaneous dorsal IP joint capsulotomy on the left side, provided satisfactory long-term results.     

The Effect of a PEEK Material‐Based External Fixator in the Treatment of Distal Radius Fractures with Non‐Transarticular External Fixation

ObjectiveTo explore the effect of a PEEK material‐based external fixator in the treatment of distal radius fractures with non‐transarticular external fixation.MethodsThere were 48 patients in this prospective comparative study. They were divided into two groups according to the materials used: the PEEK group and the titanium group. Wrist dorsiflexion, palmar flexion, pronation, supination, radial deviation, ulnar deviation, grip strength of the palm on the affected side, kneading force, Visual Analogue Scale/Score (VAS), Disabilities of the Arm, Shoulder, and Hand (DASH) score, operation time, frequency of fluoroscopy procedures, and X‐ray results were compared between the two groups. Functional recovery was evaluated at the last follow‐up according to the wrist joint evaluation criteria.ResultsThe baseline data were comparable between the two groups, and no significant differences were found in age, sex, fracture types (P > 0.05). There was no significant difference between the two groups in the results of DASH, grip strength, and recovery of pinch force and wrist function (dorsiflexion, clavicle, ulnar deviation, deviation, pronation, and supination) (P > 0.05). Normal limb function was achieved in the two groups of patients at an average of 6 weeks after surgery, and there was no significant difference in X‐ray examination radial height (10.60 ± 1.59 vs 11.00 ± 1.53, P = 0.687), radial inclination (1.11 ± 0.24 vs 1.12 ± 0.24, P = 0.798), volar tilt (10.33 ± 2.13 vs 10.00 ± 2.08, P = 0.660), ulnar variance (20.87 ± 3.00 vs 20.38 ± 3.04, P = 0.748), and step‐off persistence (1.73 ± 0.69 vs 1.68 ± 0.72, P = 0.425) between the two groups (P > 0.05). However, the operation time (54.80 ± 12.20 vs 85.23 ± 15.14, P = 0.033) and number of fluoroscopy procedures (36.93 ± 6.89 vs 64.77 ± 9.74, P = 0.000) in the PEEK group were significantly reduced compared with those in the titanium group.ConclusionCompared with the traditional titanium external fixator, the PEEK composite external fixator has advantages, such as a shorter operation time and fewer fluoroscopy procedures when used to treat different types of distal radius fracture.     

The Effect of Providing Audiovisual Surgical Information on Decisional Conflict in Patients Undergoing Plate Fixation for Distal Radius Fractures

BackgroudPatients experiencing acute trauma have limited time for their involvement in shared decision making, which may lead to decisional conflict. The purpose of this study was to evaluate whether providing audiovisual surgical information can reduce decisional conflict when deciding between surgical and nonsurgical treatment in patients with distal radius fractures (DRFs) and to evaluate factors that may affect decisional conflict.MethodsWe prospectively enrolled 50 consecutive patients who presented with acute DRFs and chose to undergo surgery, for which volar plate fixation was recommended. We randomized these patients into 2 groups. The test group was given a video clip of audiovisual surgical information in addition to regular information while the control group was only given regular information. The video clip consisted of the purpose, procedure, and effect of the surgery, precautions and complications after the operation, and other treatment options that could be performed if operation was not performed. At 2 weeks after the surgery, we evaluated patients'' decisional conflict using a decisional conflict scale (DCS). In addition, we evaluated factors that might affect decisional conflict, such as age, dominant hand, comorbidities, history of previous operations, perceived disability, and provision of the video clip.ResultsThe test group showed significantly lower DCS scores than the control group (19.6 vs. 32.1, p = 0.001). In multivariate analysis, younger age and provision of the video clip were associated with lower DCS scores.ConclusionsThis study has demonstrated that providing information through audiovisual media such as video clips could reduce decisional conflict in patients who chose to undergo plate fixation for DRFs. This study also suggests that older patients may need more careful doctor-patient communication as they have more decisional conflict than younger patients.

The Gastric Bypass for Failed Bariatric Surgical Procedures

Background: Revision of failed bariatric surgical procedures is a significant challenge for every bariatric surgeon. Methods: Evaluated are surgical difficulties, management problems and weight loss in patients with distal gastric bypass as a revisionary procedure. Eighty patients were followed up to 3 years; four were lost to follow-up. Mean age was 43; mean prebariatric surgery weight 134 kg; height 1.65 meters; body mass index 40.1; ideal body weight 62.7 kg; excess weight 70.5 kg; per cent excess weight 214%. A 250 cm stomach-to-ileocecal valve segment of small bowel was used, and the biopancreatic secretions were brought into the terminal ileum 100 cm from the ileocecal valve. Mean pouch size was 63 cc; length of hospital stay 5 days; operative blood loss 616 cc; operative time 130 min. Results: Intraoperative complications included three splenic injuries (without splenectomy). Early complications included one deep vein thrombosis, two marginal ulcers, one GI hemorrhage, one wound dehiscence, one pouch outlet obstruction and one pancreatitis. Late complications included: one death from protein malnutrition/ARDS; 21 hypoproteinemia; six protein malnutrition, and of these, three had hyperalimentation; three cholecystitis; 27 anemia; 22 incisional hernia; two staple-line disruption (reoperated); 26 low serum iron; 11 prolonged (> 6 months) diarrhea; three prolonged frequent vomiting; and two unrelated deaths (chronic myelogenous leukemia and amyotrophic lateral sclerosis). Mean excess weight loss was 83% at 12 months; 89% at 24 months; and 94% at 36 months. Conclusion: The distal gastric bypass is fraught with the operative and immediate post-operative complications experienced in any revisionary bariatric surgery. Distal gastric bypass is very effective in producing long-term weight loss. Nutritional problems are common but usually easily corrected. The most serious nutritional complication is protein malnutrition, which must be identified and corrected early. Success of this procedure is dependent upon patient compliance with proper nutrition and supplements, and regular office follow-up with monitoring of laboratory data. Patients who are noncompliant are at significant risk for complications.

The endoscopic evaluation of gastritis,gastric remnant residue,and the incidence of secondary cancer after pylorus-preserving and transverse gastrectomies

Background Pylorus-preserving gastrectomy (PPG) and transverse gastrectomy (TrG) have been accepted as function-preserving procedures for node-negative early gastric cancer. It is believed that a better quality of life is guaranteed after PPG or TrG compared to that after distal subtotal gastrectomy (DSG) with Billroth type-I reconstruction. However, objective evaluations of the gastric remnant following gastrectomy have not been widely reported, and the real advantages and disadvantages of PPG or TrG over DSG remain unclear. Moreover, the risk of secondary cancer after PPG or TrG is uncertain.Methods Between 1991 and 2000, 834 DSGs were carried out in our institute for preoperatively diagnosed patients with early gastric cancer. The degree of residual gastritis and the amount of diet residue in the gastric remnant were evaluated by annual gastrointestinal endoscopic investigations prospectively for 72 patients after PPG, 95 patients after TrG, and 60 patients after DSG. These analyses were performed using the RGB classification (residue, gastritis, bile). The incidence of disease greater than or equal to grade 2 was calculated, and the time trends of the incidence for each procedure were also studied for 3 years after gastrectomy. In addition, secondary cancer cases in the gastric remnant mucosa were checked for each procedure during this period, and the incidence of secondary cancer after each operation was calculated.Results The incidence of gastritis, of grade 2 or more, found in the gastric remnant was significantly lower after PPG (1.4%) and TrG (2.1%) than after DSG (43.3%). However, the incidence of moderate or greater residue in the gastric remnant, grade 2 or more, was significantly higher after PPG (45.8%) and TrG (40.0%) than after DSG (11.7%). The analysis of time trends of gastritis and diet residue reflected the significant advantage or disadvantage for each procedure 1 year after surgery. The analysis also included these factors without consideration of elapsed time following surgery. Two patients after PPG (2.8%) and three patients after TrG (3.2%) developed secondary cancer in the gastric remnant. No DSG-treated patient showed new cancer genesis in the remaining stomach.Conclusion PPG and TrG have the advantage over DSG in preventing postoperative gastritis in the gastric remnant. On the other hand, moderate or greater diet residue in the gastric remnant is more common after PPG or TrG than after DSG. For the risk of carcinogenesis in the remnant gastric mucosa, we could not conclude that there was any apparent difference between these range-limited gastrectomies and conventional DSG. Further study is necessary to determine the significant advantages and disadvantages of using PPG or TrG.     

A Systematic Review of Distal Interphalangeal Joint Arthrodesis

Arthrodesis of the distal interphalangeal joint of the hand is a reliable procedure for creating a painless stable joint. Numerous techniques are described within the literature for varying indications. We undertook a systematic review of all studies published within the English literature to provide a comparison of the different techniques. The published studies were predominantly of Level IV evidence. The most commonly employed techniques were Kirschner wire, headless compression screw and cerclage wires. There was no difference in infection rates. Headless compression screws appear to have increased union rates but are associated with complications not seen with other well-established and cheaper techniques. The screw diameter is often similar to or larger than the joint itself, which can result in penetration. Furthermore, they limit the available angle for achieving fusion. Other than in terms of union, there is insufficient evidence to show the headless compression screw is superior to other techniques.
