dental inclusion
2022
The inclusion of both maxillary permanent central incisors is uncommon. This condition compromises face aesthetics, phonation and masticatory function. Therefore, early diagnosis is essential to avoid complications and failures. There are various reasons for inclusion, but supernumerary teeth are the leading cause. Early causes of removal and rapid expansion of the palate determine a high probability of success with the spontaneous eruption of the impacted elements. However, it is often necessary to proceed with a surgical–orthodontic treatment. The inclination of teeth in relation to the midline and the root maturation degree determine prognosis and therapeutic timing. In this case report, the orthopantomogram (OPG) X-ray of a 9-year-old boy revealed two impacted supernumerary teeth in the anterior maxillary region, preventing the eruption of the permanent upper central incisors. The impacted supernumerary teeth were surgically removed at different times. A straight wire multibrackets technique associated with a fixed palatal appliance was used. The palatal appliance featured an osteomucous resin support at the level of the retroincisal papilla. Subsequently, surgical exposure was carried out using the closed eruption technique and elastic traction, bringing 11 and 21 back into the arch.

Tips and tricks for robotic pancreatoduodenectomy with superior mesenteric/portal vein resection and reconstruction
2023
BackgroundOpen pancreatoduodenectomy with vein resection (OPD-VR) is now standard of care in patients who responded to neoadjuvant therapies. Feasibility of robotic pancreatoduodenectomy (RPD) with vein resection (RPD-VR) was shown, but no study provided a detailed description of the technical challenges associated with this formidable operation. Herein, we describe the trips and tricks for technically successful RPD-VR.MethodsThe vascular techniques used in RPD-VR were borrowed from OPD-VR, as well as from our experience with robotic transplantation of both kidney and pancreas. Vein resection was classified into 4 types according to the international study group of pancreatic surgery. Each type of vein resection was described in detail and shown in a video.ResultsBetween October 2008 and November 2021, a total of 783 pancreatoduodenectomies were performed, including 233 OPDs-VR (29.7%). RPD was performed in 256 patients (32.6%), and RPDs-VR in 36 patients (4.5% of all pancreatoduodenectomies; 15.4% of all pancreatoduodenectomies with vein resection; 14.0% of all RPDs). In RPD-VR vein resections were: 4 type 1 (11.1%), 10 type 2 (27.8%), 12 type 3 (33.3%) and 10 type 4 (27.8%). Vascular patches used in type 2 resections were made of peritoneum (n = 8), greater saphenous vein (n = 1), and deceased donor aorta (n = 1). Interposition grafts used in type 4 resections were internal left jugular vein (n = 8), venous graft from deceased donor (n = 1) and spiral saphenous vein graft (n = 1).There was one conversion to open surgery (2.8%). Ninety-day mortality was 8.3%. There was one (2.8%) partial vein thrombosis, treated with heparin infusion.ConclusionsWe have reported 36 technically successful RPDs-VR. We hope that the tips and tricks provided herein can contribute to safer implementation of RPD-VR. Based on our experience, and according to data from the literature, we strongly advise that RPD-VR is performed by expert surgeons at high volume centers.

Among infants with isolated cleft palate, whether primary surgery at 6 months of age is more beneficial than surgery at 12 months of age with respect to speech outcomes, hearing outcomes, dentofacial development, and safety is unknown.
We randomly assigned infants with nonsyndromic isolated cleft palate, in a 1:1 ratio, to undergo standardized primary surgery at 6 months of age (6-month group) or at 12 months of age (12-month group) for closure of the cleft. Standardized assessments of quality-checked video and audio recordings at 1, 3, and 5 years of age were performed independently by speech and language therapists who were unaware of the trial-group assignments. The primary outcome was velopharyngeal insufficiency at 5 years of age, defined as a velopharyngeal composite summary score of at least 4 (scores range from 0 to 6, with higher scores indicating greater severity). Secondary outcomes included speech development, postoperative complications, hearing sensitivity, dentofacial development, and growth.
We randomly assigned 558 infants at 23 centers across Europe and South America to undergo surgery at 6 months of age (281 infants) or at 12 months of age (277 infants). Speech recordings from 235 infants (83.6%) in the 6-month group and 226 (81.6%) in the 12-month group were analyzable. Insufficient velopharyngeal function at 5 years of age was observed in 21 of 235 infants (8.9%) in the 6-month group as compared with 34 of 226 (15.0%) in the 12-month group (risk ratio, 0.59; 95% confidence interval, 0.36 to 0.99; P = 0.04). Postoperative complications were infrequent and similar in the 6-month and 12-month groups. Four serious adverse events were reported (three in the 6-month group and one in the 12-month group) and had resolved at follow-up.
Medically fit infants who underwent primary surgery for isolated cleft palate in adequately resourced settings at 6 months of age were less likely to have velopharyngeal insufficiency at the age of 5 years than those who had surgery at 12 months of age.

Background: Tracheostomy can be performed safely in patients with coronavirus disease 2019 (COVID-19). However, little is known about the optimal timing, effects on outcome, and complications. Methods: A multicenter, retrospective, observational study. This study included 153 tracheostomized COVID-19 patients from 11 intensive care units (ICUs). The primary endpoint was the median time to tracheostomy in critically ill COVID-19 patients. Secondary endpoints were survival rate, length of ICU stay, and post-tracheostomy complications, stratified by tracheostomy timing (early versus late) and technique (surgical versus percutaneous). Results: The median time to tracheostomy was 15 (1–64) days. There was no significant difference in survival between critically ill COVID-19 patients who received tracheostomy before versus after day 15, nor between surgical and percutaneous techniques. ICU length of stay was shorter with early compared to late tracheostomy (p < 0.001) and percutaneous compared to surgical tracheostomy (p = 0.050). The rate of lower respiratory tract infections was higher with surgical versus percutaneous technique (p = 0.007). Conclusions: Among critically ill patients with COVID-19, neither early nor percutaneous tracheostomy improved outcomes, but did shorten ICU stay. Infectious complications were less frequent with percutaneous than surgical tracheostomy.

A new minimally invasive technique for the repair of diastasis recti: a pilot study
2021
BackgroundDiastasis recti is an abdominal wall defect that occurs frequently in women during pregnancy. Patients with diastasis can experience lower back pain, uro-gynecological symptoms, and discomfort at the level of the defect. Diastasis recti is diagnosed when the inter-rectus distance is > 2 cm. Several techniques, including both minimally invasive and open access surgical treatment, are available. Abdominoplasty with plication of the anterior rectus sheath is the most commonly used, with the major limitation of requiring a wide skin incision. The new technique we propose is a modification of Costa’s technique that combines Rives–Stoppa principles and minimally invasive access using a surgical stapler to plicate the posterior sheaths of the recti abdominis.MethodsIt is a fully laparoscopic technique. The pneumoperitoneum is induced from a sovrapubic trocar, placed using an open access technique. The posterior rectus sheath is dissected from the rectus muscle using a blunt dissector to create a virtual cavity. The posterior sheets of the recti muscles are plicated using an endo-stapler. A mesh is then placed in the retromuscular space on top of the posterior sheet without any fixation. Using a clinical questionnaire, we analyzed the outcomes in 74 patients who underwent minimally invasive repair for diastasis of the rectus abdominis sheath.ResultsSeventy-four patients (9 men and 65 women) were treated using this technique. Follow-up was started two months after surgery. All procedures were conducted successfully. There were no major complications or readmissions. No postoperative infections were reported. There were two recurrences after six months. There was a significant reduction in symptoms.ConclusionsThis new method is feasible and has achieved promising results, even though a longer follow-up is needed to objectively assess this technique.

Techniques for Cervical Laminoplasty
2026
Study Design
Narrative review.
Objective
The objective of this review was to discuss the various surgical techniques and developments in cervical laminoplasty and outline any reported differences in outcomes between the different techniques used.
Methods
A PubMed literature search was performed using the terms “expansive”, “open door laminoplasty”, “cervical”, “double door laminoplasty”, “French door laminoplasty”, and “endoscopic”. All articles written or translated into English were considered and synthesized to provide a narrative overview of cervical laminoplasty techniques.
Results
Cervical laminoplasty techniques can be categorized either into “open door” or “double door” (“French door”) laminoplasty. Several iterations of each technique to address long-term closure of the laminoplasty, muscle preservation, and migration of bone grafts have been developed. There are no consistent reported differences in outcomes in the literature between the 2 techniques for individuals with degenerative cervical myelopathy.
Conclusions
Cervical laminoplasty is an effective surgical technique to expand canal size and achieve spinal cord decompression in the context of degenerative cervical myelopathy secondary to spondylosis or OPLL. Both the “open door” and “double door” laminoplasty techniques generally provide equivalent outcomes. Minimally invasive techniques including endoscopic approaches also continue to evolve, and future research comparing all approaches is warranted.

Standardization of surgical technique of the fundoring method for laparoscopic gastric bypass
2025
One of the successful strategies for avoiding reflux esophagitis and other issues following gastric bypass is the FundoRing method of gastric bypass with fundoplication employing the excluded (remnant) portion of the stomach. This study aims to describe the standardization of the different specific steps of surgical techniques of FundoRing for performing one anastomosis gastric bypass (OAGB) and describes the two-year outcomes of the standardized procedure compared to non-standardized surgery. This work describes the update of the details of standardization of the surgical technique of the FundoRing method for laparoscopic gastric bypass based on previously non-standardized experiments. The study design was a clinical, comparative, two-year follow-up study involving two groups using a one-anastomotic gastric bypass (OAGB). FundoRingOAGB was performed in the first (standardization) group, and in the second group (a non-standardized group), the NissenOAGB was used. The specific steps of the FundoRing surgical procedure are: mandatory division of the gastrosplenic ligament for the creation of a circular fundoplication 5 cm in length, and supplemented by a partial fundoplication of another 2 cm. The total size of the fundoplication wrap is 7 cm. A suture of fundoplication wrap is created with autologous tissues at 3 and 6 o’clock on the “dial” of the gastric pouch between the left (anterior) and right (posterior) parts of the wrap, thus performing double calibration, and the FundoRing is ready. At 24 months post-treatment, BMI changes were as follows: from 40.7 ± 5.9 (31–53) kg/m
2
to 24.3 ± 2.8 (19–29) kg/m
2
in “after standardisation” (first) group, versus 40.9 ± 6.3 (33–53) kg/m
2
to 28.1 ± 3.9 (24–34) kg/m
2
in “before standardisation” (second) group. Over 2 years, no cases of serious complications were observed in the FundoRingOAGB group (standardization group) compared to the NissenOAGB (non-standardization group), which had 11 (22%) complications (
p
= 001). The surgical technique of FundoRing has specific, distinctive steps. It involves a wider mobilization of the fundus and the need to perform double calibration of the wrap when creating a circular or partial fundoplication, oriented toward the stapler suture of the gastric pouch to create a living ring (band) from autologous tissue. The standardization of the surgical technique of the FundoRing method for laparoscopic gastric bypass improves weight loss outcomes and complication prevention.

Implantation of Ahmed glaucoma valve is an effective surgical technique to reduce intraocular pressure in patients affected with glaucoma. While in the past, the use of this device was reserved to glaucoma refractory to multiple filtration surgical procedures, up-to-date mounting experience has encouraged its use also as a primary surgery for selected cases. Implantation of Ahmed glaucoma valve can be challenging for the surgeon, especially in patients who already underwent previous multiple surgeries. Several tips have to be acquired by the surgeon, and a long learning curve is always needed. Although the valve mechanism embedded in the Ahmed glaucoma valve decreases the risk of postoperative hypotony-related complications, it does not avoid the need of a careful follow-up. Complications related to this type of surgery include early and late postoperative hypotony, excessive capsule fibrosis around the plate, erosion of the tube or plate edge, and very rarely infection. The aim of this review is to describe surgical technique for Ahmed glaucoma valve implantation and to report related complications.

BackgroundThe relationship between sleeve gastrectomy (SG) morphology and long-term weight-loss and gastroesophageal reflux disease (GERD) outcomes is unknown.MethodsAll patients (n = 268) undergoing SG performed by 3 surgeons at a single academic institution from January 1, 2010 to December 31, 2012 were included. Long-term weight-loss and GERD outcomes were available for 90 patients which were incorporated in analyses. SG morphology was determined from postoperative day 1 upper gastrointestinal series (UGIS) available from 50 patients. Images were independently categorized using previously published methodology as Dumbbell (38%), Lower Pouch (22%), Tubular (26%), or Upper Pouch (14%) by Radiologist and Surgeon. Radiologist categorization was used when disagreement occurred (8%). Univariable analyses were conducted to explore potential associations between SG morphology, weight loss, and GERD outcomes.ResultsFollow-up was 8.2 ± 0.9 years. Population characteristics included age of 45.1 ± 10.8 years, female sex in 83.3%, and hiatal hernia repair (HHR) performed at index SG in 17.8%. Surgeons did not preferentially achieve a specific SG morphology. Changes from preoperative obesity and associated diseases comprised body mass index (BMI) (49.5 ± 7.6 vs. 39.2 ± 9.4 kg/m2; p < 0.0001), diabetes mellitus (30.0 vs. 12.2%; p = 0.0006), hypertension (70.0 vs. 54.4%; p = 0.0028), hyperlipidemia (42.2 vs. 24.2%;p = 0.0017), obstructive sleep apnea (41.1 vs. 15.6%; p < 0.0001), osteoarthritis (48.9 vs. 13.3%; p < 0.0001), back pain (46.5 vs. 28.9%; p = 0.0035), and medications (4.8 ± 3.3 vs. 3.7 ± 3.5; p < 0.0001). Dumbbell SG morphology was associated with lesser reduction in BMI at follow-up (-−6.8 ± 7.2 vs. −12.4 ± 8.3 kg/m2; p = 0.0196) while greater BMI change was appreciated with Lower Pouch SG shape (−16.9 ± 9.9 vs. −8.4 ± 6.8 kg/m2; p = 0.0017). GERD was more prevalent at follow-up than baseline (67.8 vs. 47.8%; p < 0.0001). GERD-specific outcomes included de novo (51.1%), persistent (27.9%), worsened (58.1%), and resolved (14.0%) disease. Ten patients underwent reoperation for refractory GERD with SG morphology corresponding to Dumbbell (n = 5) and Upper Pouch (n = 1) for those with available UGIS. Univariable analyses showed that patients with GERD experienced a larger reduction in BMI compared with patients without GERD (−11.8 ± 7.7 vs. −7.0 ± 5.1 kg/m2; p = 0.0007). Patient age, surgeon, morphology category, and whether a HHR was done at index SG were not associated with the presence of any, de novo, or worsened GERD. Female sex was associated with worsened GERD (96.0 vs. 4.0%; p = 0.0455). Type of calibration device, distance from staple line to pylorus, and whether staple line reinforcement was used were not associated with SG morphology classification.ConclusionThis is the first study assessing the impact of SG morphology on long-term weight loss and GERD. Our data suggest an association between SG morphology and long-term weight loss but not with GERD outcomes. Current technical standards may be limited in reproducing the same SG morphology. This information may help guide the technical optimization and standardization of SG.Surgeons did not favor a specific SG morphology (1). Our results signal to a relationship between radiographic assessment of SG morphology and long-term weight-loss outcomes with Dumbbell classification correlated with lesser reduction in BMI (2a) and Lower Pouch morphology associated with superior weight loss (2b).

Background
Posthepatectomy liver failure is the most severe complication after major hepatectomies and it is associated with an insufficient future liver remnant (FLR). Associating liver partition and portal vein ligation (PVL) has recently been described as a revolutionary strategy to induce a rapid and large FLR volume increase. We aim to describe our surgical technique, patient management, and preliminary results with this new two-stage approach.
Technique
During the first stage, liver partition and PVL of the diseased hemiliver are performed. The completion surgery is carried out after volumetric studies have demonstrated a sufficient FLR and provided the patient is in good condition. This is usually achieved after 7 days. In the second step, the patient undergoes a completion surgery with right hepatectomy, right trisectionectomy, or left trisectionectomy.
Results
Fifteen patients with advanced liver tumors were treated. Nine patients were males and the mean age was 54 years old. The mean difference between the preoperative and postoperative FLR volume was 303 ml (
p
< 0.001), which represented a mean volume increase of 78.4 %. All resections were R0. Morbidity and mortality rates were 53 and 0 %, respectively. The average hospital stay was 19 days.
Conclusions
The presented technique was feasible and safe in the hands of experienced hepatobiliary surgeons, with satisfactory short-term results. It induces rapid liver hypertrophy and at the same time it offers the possibility of cure to patients previously declared unresectable.
