Most operations in the abdominal cavity and chest can be performed using minimally invasive techniques. As yet it has not been determined which laparoscopic procedures are preferable to the same operations done through conventional laparotomy. However, most surgeons who have completed the learning curves of these procedures believe that most minimally invasive techniques will be scientifically recognized soon. The evolution, validation and justification of advanced laparoscopic surgical methods seem inevitable. Most believe that the trend towards procedures that minimize or eliminate the trauma of surgery while adhering to accepted surgical principles is irreversible. The functional results of laparoscopic antireflux surgery in the seven years since its inception have been virtually identical to the success curves generated with open fundoplication in past years. Furthermore, overall patient outcomes with laparoscopic procedures have been superior to outcomes with the traditional approach. Success is determined by patient selection and operative technique. Patient evaluation should include esophagogastroduodenoscopy, barium swallow, 24 h pH study and esophageal motility study. Gastric emptying also should be evaluated. Patients who have abnormal propulsion in the esophagus should not receive a complete fundoplication (Nissen) because it adds a factor of obstruction. Dor or Toupet procedures are adequate alternatives. Prokinetic agents, dilation or pyloroplasty are used for pyloric obstruction ranging from little to more severe. Correcting reflux laparoscopically is more difficult in patients with obesity, peptic strictures, paraesophageal hernias, short esophagus, or a history of previous upper abdominal or antireflux surgery.

Abstract   Minimally invasive techniques are being increasingly used in the treatment of esophageal cancer. The learning curve for minimally invasive esophagectomy (MIE) is variable and can have an impact upon training delivered within residency and fellowship programmes. The aims of this review are to critically appraise current literature on the learning curve for MIE, identify what parameter(s) is used to quantify achieving competence and determine if there is evidence of resultant impact on surgical training. Methods A search of the major reference databases (MEDLINE, EMBASE, Cochrane) was performed with no time limits up to the date of the search (February 2020). Results were screened in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and study quality assessed using the Newcastle-Ottawa Scale for cohort studies. Results Twenty-one studies comprising 2720 patients were included- 17 studies reported on a combination of thoracoscopic, hybrid and total MIE, 3 studies reported robotic assisted alone and 1 study evaluated robotic assisted and thoracoscopic esophagectomy. 3 studies used a cumulative sum (CUSUM) analysis to define learning, 1 study used CUSUM and another parameter and 17 studies used one or more parameters. Quantification of surgical competence was variable and ranged from 12–80 cases for robotic surgery and 12–60 cases for other modes of MIE. One study reported trainees achieving MIE skills quicker if mentoring surgeons had attained proficiency on the learning curve. Conclusion Learning curves in MIE remain ill-defined with limited evidence on impact upon training received by residents and fellows. Additionally, the parameters used to define achievement of surgical competency is heterogenous. As minimally invasive techniques are increasingly adopted, specific standards to help define competence need to be identified and agreed on. This could help in designing training programmes and improve the rate of achieving competency.

Gummy smile is a characteristic in which the patient exposes more than 2 mm of keratinized gingiva in forced smile. With a multifactorial cause, its correct planning depends directly on the correct diagnosis. Usually, the procedures that involve manipulation and the enlargement of the aesthetical crown lengthening are surgical. The objective of this case series was to show the advantages of surgical crown augmentation surgery in aesthetic areas with minimally invasive techniques. Three cases of gummy smile were presented, with different treatment plans and techniques for execution. In the 3 cases, bone removal was performed with piezoelectric ultrasound, which made the postoperative more comfortable for patients. These cases illustrate the use of technology to reduce morbidity in patients who need to undergo bone removal to treat gingival smile.

Surgery and chemotherapy have historically been the mainstay of treatment in patients with metastatic disease. However there are many alternative therapies available to relieve the symptoms and morbidity of metastases. In this paper, we review the role and highlight the advantages of minimally invasive techniques employed in patients with pulmonary and bone metastases.

AbstractSecondary deformities of repaired cleft lips are an unfortunate complication despite the meticulous approach of modern primary procedures. Most of these surgeries take place in the patient's early life and must be strategically planned to provide optimal cosmesis with minimal interventions. Depending on the level of severity, treatment of the secondary deformities ranges from noninvasive or minimally invasive techniques to complete revision cheiloplasty. Many novel topical, injectable, and laser therapies have allotted physicians more technical flexibility in treating superficial distortions. Nonetheless, surgical techniques such as diamond excision and adjacent tissue transfer remain popular and useful reconstructive modalities. Deformities involving the orbicularis oris must be completely taken down to allow full access to the muscle. Complete revision cheiloplasty requires recreation of the cleft defect and reconstruction similar to the primary repair. Due to the myriad of presentations of these secondary deformities, familiarity with the various treatments available is imperative for any cleft surgeon.

Study Design: Broad narrative review. Objective: To review and summarize the current literature on the cost efficacy of performing ACDF, lumbar discectomy and short segment fusions of the lumbar spine performed in the outpatient setting. Methods: A thorough review of peer- reviewed literature was performed on the relative cost-savings, as well as guidelines, outcomes, and indications for successfully implementing outpatient protocols for routine spine procedures. Results: Primary elective 1-2 level ACDF can be safely performed in most patient populations with a higher patient satisfaction rate and no significant difference in 90-day reoperations and readmission rates, and a savings of 4000 to 41 305 USD per case. Lumbar discectomy performed through minimally invasive techniques has decreased recovery times with similar patient outcomes to open procedures. Performing lumbar microdiscectomy in the outpatient setting is safe, cheaper by as much as 12 934 USD per case and has better or equivalent outcomes to their inpatient counterparts. Unlike ACDF and lumbar microdiscectomy, short segment fusions are rarely performed in ASCs. However, with the advent of minimally invasive techniques paired with improved pain control, same-day discharge after lumbar fusion has limited clinical data but appears to have potential cost-savings up to 65-70% by reducing admissions. Conclusion: Performing ACDF, lumbar discectomy and short segment fusions in the outpatient setting is a safe and effective way of reducing cost in select patient populations.

Spontaneous intracerebral hemorrhage is a serious public health problem and is fatal in 30%–50% of all occurrences. The role of open surgical management of supratentorial intracerebral hemorrhage is still unresolved. A recent consensus conference sponsored by the National Institutes of Health suggests that minimally invasive techniques to evacuate clots appear to be a promising area and warrant further investigation. In this paper the authors review past, current, and potential future methods of treating intraparenchymal hemorrhages with minimally invasive techniques and review new data regarding the role of stereotactically placed catheters and thrombolytics.
