Is Needlescopic Cholecystectomy a Safe Way to Improve Mininvasiveness and Cosmesis in Young Female Patients?

INTRODUCTION: Needlescopic cholecystectomy (NC) was introduced in the late 1990s. It uses a reduced trocar caliber in an otherwise standard four-port laparoscopic cholecystectomy (LC) and seeks to achieve "scarless" surgery without compromising patient safety. MATERIALS AND METHODS: Between May 2016 and November 2017, 29 patients underwent elective NC at the Department of General Surgery of Sant'Andrea Hospital (La Spezia, Italy). Inclusion criteria were female sex, age between 18 and 45 years, good performance status (ASA 1-2) and BMI lower than 25. Twenty-one patients underwent a standard 4-port technique: 12mm port in the supraumbilical area, 5mm port in the subxiphoid position, 3mm port in the mid-epigastric area and another 3 mm port in the right mid-clavicular position. In 8 patients, 3mm ports were replaced by 2mm angiocath. A Critical View of Safety (CVS) was achieved in all procedures. Intra-operative cholangiography (IOC) via the cystic duct before any transection of the structures was routinely performed in selected cases, such as those with an unclear biliary anatomy or risk factors for main-duct stones. In our institution, laparoscopic transcystic common bile duct (CBD) exploration is routinely performed in CBD lithiasis. RESULTS: The mean operative time was 66.79 min (range 25-120 min). IOC was performed in 12 patients (41.4%) with suspected choledocolythiasis. There was no conversion to conventional laparoscopic cholecystectomy or open cholecystectomy. The mean hospital stay was 1.48 days (1-7 days). A Clavien-Dindo IIIB complication occurred in one patient on the third postoperative day. The mean VAS pain score was 3 (0-7). Closure of the skin with primary intention was achieved in all patients. Mean return to work was 6.76 days (3-15 days) and the mean return to previous physical activity was 12.17 days (4-30 days). All of the patients completed the Scar Satisfaction Questionnaire: 26 (89.7% ) and 3 patients (10.3%) were very satisfied and satisfied, respectively. CONCLUSION: Any effort to reduce invasiveness and improve cosmesis must not jeopardize safety. Our case series demonstrates that needlescopy can be safely associated with intraoperative cholangiography to recognize CBD stones. This technique offers the advantage of minor postoperative pain, better cosmesis results, early return to routine life activities and great satisfaction for the patient. Needlescopy is a valuable and safe alternative that is suitable for elective cholecystectomy in properly selected patients, such as young female patients.

Genetic tests in lymphatic vascular malformations and lymphedema.

Syndromes with lymphatic malformations show phenotypic variability within the same entity, clinical features that overlap between different conditions and allelic as well as locus heterogeneity. The aim of this review is to provide a comprehensive clinical genetic description of lymphatic malformations and the techniques used for their diagnosis, and to propose a flowchart for genetic testing. Literature and database searches were performed to find conditions characterised by lymphatic malformations or the predisposition to lymphedema after surgery, to identify the associated genes and to find the guidelines and genetic tests currently used for the molecular diagnosis of these disorders. This search allowed us to identify several syndromes with lymphatic malformations that are characterised by a great heterogeneity of phenotypes, alleles and loci, and a high frequency of sporadic cases, which may be associated with somatic mutations. For these disorders, we found many diagnostic tests, an absence of harmonic guidelines for molecular diagnosis and well-established clinical guidelines. Targeted sequencing is the preferred method for the molecular diagnosis of lymphatic malformations. These techniques are easy to implement and have a good diagnostic success rates. In addition, they are relatively inexpensive and permit parallel analysis of all known disease-associated genes. The targeted sequencing approach has improved the diagnostic process, giving patients access to better treatment and, potentially, to therapy personalised to their genetic profiles. These new techniques will also facilitate the prenatal and early postnatal diagnosis of congenital lymphatic conditions and the possibility of early intervention.

Surgical treatment of recidivist lymphedema.

Lymphedema is a chronic disease with a progressively ingravescent evolvement and an appearance of recurrent complications of acute lymphangitic type; in nature it is mostly erysipeloid and responsible for a further rapid increase in the volume and consistency of edema. The purpose of this work is to present our experience in the minimally invasive treatment for recurrence of lymphedema; adapting techniques performed in the past which included large fasciotomy with devastating results cosmetically; but these techniques have been proposed again by the use of endoscopic equipment borrowed from the advanced laparoscopy surgery, which allows a monoskin access of about one cm.

Celiac axis compression syndrome: laparoscopic approach in a strange case of chronic abdominal pain in 71 years old man.

Celiac Axis Compression Syndrome by the Median Arcuate Ligament is a very rare condition characterized by chronic postprandial abdominal pain (angina abdominis), nausea, vomiting, which occurs mostly in young patients. The main treatment is a surgical procedure that consists of the division of the arcuate ligament combined with the section of the close diaphragmatic crus and the excision of the celiac plexus. Actually laparoscopic management is feasible and safe.

[Technical variant of mechanical prolapsectomy: transanal prolapsectomy with anoscopy]. / Varianti tecniche della prolassectomia meccanica: la TPA.

Mechanical mucoprolapsectomy for surgical treatment of rectal prolapse and haemorrhoidal pathology is a widespread practice that has been consolidated by the experience of many medical centres. We have been using a variant system (TPA, transanal prolapsectomy with anoscopy) for about two years. The main feature of this technique is the access route. We performed 51 transanal mucoprolapsectomies over a period of 20 months. During the surgical intervention, in rachianaesthesia, patients are placed in a prone position with minimal snapping of the operating cot. The use of a mobile, versatile tool ("the beak") for constructing the purse-string suture makes for very good manageability. Continuous visual and digital control of each operating step permits immediate correction where necessary. This technique is safe and effective and affords the possibility of single-operator intervention, the second operator proving superfluous in all stages of the operation.

Microsurgery for treatment of peripheral lymphedema: long-term outcome and future perspectives.

Authors report over 30 years of their own clinical experience in the treatment of chronic peripheral lymphedemas by microsurgical techniques performed at the Center of Lymphatic Surgery of the University of Genoa, Italy. Over 1,500 lymphedema patients were treated with microsurgical techniques. Derivative lymphatic-venous techniques were most often used. For those cases where a venous disease was associated to lymphedema, reconstructive lymphatic microsurgery techniques were performed (lymphatic-venous-lymphatic-plasty). Objective assessment was undertaken by water volumetry and lymphoscintigraphy. Volume changes showed a significant improvement in over 83%, with an average follow-up of more than 10 years. There was an 87% reduction in the incidence of cellulitic attacks after microsurgery. Microsurgical lymphatic-venous anastomoses have a place in the treatment of peripheral lymphedema and should be the therapy of choice in patients who are not sufficiently responsive to nonoperative treatment. Improved results can be expected with operations performed at earlier lymphedema stages.

The lymphatics in the pathophysiology of thoracic and abdominal surgical pathology: immunological consequences and the unexpected role of microsurgery.

The authors report their experience in the diagnosis and treatment of lymphatic and chylous disorders in the thoracic and abdominal areas. Sixteen patients (10 adults, 6 children) affected by primary chylous ascites with associated syndromes and consequent immunological incompetence were studied. Diagnostic investigations included abdominal sonography scans, lymphoscintigraphy, and lymphography combined with computed tomography and laparoscopy. Surgical treatment included laparoscopy, drainage of ascites and/or the chylothorax, treatment of abdominal and retroperitoneal chylous leaks, exeresis of lymphodysplastic tissues, ligation of incompetent lymph vessels also by CO(2) LASER, and chylo-venous and lympho-venous microsurgical shunts. Eleven patients did not have a relapse of the ascites and four patients had a persistence of a small quantity of ascites with no protein imbalance. All patients had an improvement of their immunocompetence. Median follow-up was 5 years. We demonstrated that the use of microsurgery is remarkably advantageous for performing a causal treatment of the dysfunction.

Diagnosis and management of primary chylous ascites.

BACKGROUND: Chylous ascites is the accumulation of triglyceride-rich, free, milk-like peritoneal fluid caused by the presence of intestinal lymph in the abdominal cavity. Primary chylous ascites is uncommon. We present our experience in the diagnosis and treatment of this condition. METHODS: Twelve patients (7 adults, 5 children) affected by primary chylous ascites were studied. Diagnostic investigations included abdominal sonography scans, lymphoscintigraphy, and lymphography combined with computed tomography (CT) with intravenous and intralymphatic lipid-soluble contrast, and laparoscopy. Magnetic resonance imaging was used when lymphography and lymphatic CT were not able to define the dysplasia well, or in the presence of lymphatic dilatation. Surgical treatment included laparoscopy (12/12), drainage of ascites (12/12), the search for and treatment of abdominal and retroperitoneal chylous leaks (12/12), exeresis of lymphodysplastic tissues (12/12), ligation of incompetent lymph vessels (9/12), carbon dioxide laser treatment (cut and welding effects) of the dilated lymph vessels using an operating microscope for magnification (9/12), and chylovenous and lymphovenous microsurgical shunts (7/12). RESULTS: Eight patients did not have a relapse of the ascites, and three patients had a persistence of a small quantity of ascites with no protein imbalance. Postoperative lymphoscintigraphy in seven patients confirmed better lymph flow and less lymph reflux. Median follow-up was 5 years (range, 3 to 7 years). We observed early relapse of chylous ascites in only one case that required a peritoneal-jugular shunt and led to good outcome. CONCLUSION: Primary chylous ascites is closely correlated to lymphatic-lymphonodal dysplasia that does not involve a single visceral district alone. Medical preoperative treatment played an essential role in the global management of this complex pathology. We demonstrated that the use of laparoscopy is remarkably advantageous for confirming diagnosis, for draining the ascites, and for evaluating the extension of the dysplasia. Our diagnostic work-up provided us with an exact diagnostic assessment and allowed us to plan a precise surgical approach.

[Prevention of lymphoedema secondary to the treatment of breast cancer: a case report and proposal for a prevention protocol]. / La prevenzione del linfedema secondario al trattamento del tumore della mammella: dal caso clinico ad una proposta di protocollo di prevenzione.

Secondary lymphoedema of the upper limbs is a fairly frequent complication of breast cancer treatment. It is related to dissection of the axillary lymph nodes, and manifests itself in the form of clinically important lymphostasis, particularly when the dissection is combined with radiotherapy. Despite the fact that the surgical treatment of mammary cancer has become more conservative and, at the same time, radiotheraphy (when necessary) now proves less aggressive and more efficacious, secondary lymphoedema is still reported with incidence rates ranging from 5 to 25%, with an increase of up to 35% and more, when dissection of the axillary lymph nodes is followed by radiotherapy. The aim of this study was to highlight the essential importance of an early diagnosis of secondary lymphoedema, above all in relation to the prevention of this pathology. We report the case of a patient who, at the same time as the axillary lymphnode dissection, underwent a microsurgical operation consisting in the construction of lymphatic-venous shunts in the arm as a preventive measure, because lymphoscintigraphy of the upper limbs, carried out in advance, had revealed a predisposition to the development of lymphedema.
