The DOLFIN method: a novel laparoscopic Billroth-I gastroduodenostomy for gastric cancer with duodenal invasion.

Laparoscopic Billroth-I gastroduodenostomy using a delta-shaped anastomosis is safe and feasible. However, it is often difficult to perform in patients who have a short posterior wall of the duodenum. Thus, we have developed a new method named duodenal overlap functional anastomosis with linear stapler (DOLFIN). We hereby report the technical details of the new method and our preliminary experience performing it. After the completion of lymphadenectomy, the duodenum was transected craniocaudally with an endoscopic linear stapler. The hepatoduodenal mesentery was dissected approximately 4cm along the duodenal bulb, and the anastomosis between the posterior wall of the stomach and the lesser curvature of the duodenum was created. The common entry hole was then transected using an endoscopic linear stapler, and the anastomosis was finally completed. There were 36 patients with gastric cancer who underwent laparoscopic distal gastrectomy (LDG) or robotic distal gastrectomy (RDG) with B-I reconstruction using DOLFIN. There were no postoperative complications classified as C-D grade 3 or more and complications related to anastomosis, such as anastomotic leak or stenosis. Our DOLFIN gastroduodenostomy can be performed safely. In addition, it results in good postoperative outcomes. A long-term comparative study is required to further evaluate the clinical usefulness of this method.

Combined laparoscopic lymphoadenectomy of lateral pelvic and inguinal nodal metastases using indocyanine green fluorescence imaging guidance in low rectal cancer after preoperative chemoradiotherapy: a case report

BackgroundIntraoperative near-infrared fluorescence (NIR) imaging with indocyanine green (ICG) can demonstrate real-time lymphatic drainage and thus improve the accuracy and completeness of lymphadenectomy in colorectal cancer surgery. However, it has not been utilized in the inguinal lymphadenectomy in rectal cancer. This study aimed to describe a case of combined laparoscopic lymphadenectomy of left lateral pelvic and inguinal nodal metastases using NIR imaging with ICG imaging guidance for a rectal cancer patient with left lateral pelvic and inguinal lymph node metastases.Case presentationA 26-year-old man presented rectal cancer located 7 cm from the anal verge and enlarged lymph nodes in the left inguinal area. Pretreatment workup revealed rectal cancer with left lateral pelvic and inguinal lymph node metastases. The patient received preoperative chemoradiotherapy (pCRT), including radiation (total dose of 50.4 Gy in 28 fractions) to the whole pelvis and bilateral inguinal regions together with eight cycles of FOLFOX (oxaliplatin, fluoropyrimidine, and leucovorin) and three cycles of bevacizumab targeted chemotherapy. After pCRT, both colonoscopy and MR scan revealed a significant response of the primary tumor to pCRT, while MR scan revealed enlarged left lateral pelvic and inguinal lymph nodes. After four months from the completion of radiation (2 months after the last course of bevacizumab targeted therapy), the patient underwent laparoscopic-assisted ultra-low anterior resection and lymphadenectomy of left lateral pelvic and inguinal nodal metastases using ICG-NIR fluorescence imaging. The combined procedure was performed successfully without perioperative complication. Total operative time was 480 min and estimated blood loss 50 mL. Totally 34 lymph nodes were retrieved.ConclusionsThis is the first report of the safety and feasibility of ICG-NIR fluorescence imaging-guided laparoscopic lymphadenectomy of left lateral pelvic and inguinal nodal metastases in managing low rectal cancer with lateral pelvic and inguinal LNs metastases.

Costes asociados al diagnóstico y tratamiento quirúrgico del cáncer de mama precoz

ObjectiveThe aim of our study was to identify the costs associated with the diagnosis and surgical procedure in a cohort of patients with early breast cancer. MethodWe performed a costs study, referred to the preoperatory radiological-histological study, surgical procedure and inpatient/outpatient health service in a cohort of 224 patients diagnosed and operated on early-stage breast from June 2012 to December 2016. ResultsBreast conserving surgery in outpatient health service applied to lumpectomy with sentinel lymph node biopsy compared to carrying it out in the inpatient setting, contributed to a saving of 2085€ per patient, and total of 289,815€. Following the ACOSOG (American College of Surgeons Oncology Group) trial in 18 patients with tumor-involved sentinel node, no further axillary specific treatment (completion of lymphadenectomy) was made, allowing a saving of 37,530€. In most patients our study have not showed benefit from diagnostic/preoperative breast MRI, leading to an over cost of 37,179€. The surgical rescission without showing the presence of residual tumor burden, led to an additional cost of 11,592€. Conclusions-Breast conserving surgery with sentinel lymph node biopsy in outpatient health service supposed an important economical saving of resources, without compromising the well-being and prognosis of our patients.-The diagnostic/preoperative MRI in all the patients and the surgical rescissions led to an over cost that could be avoided in most of the cases.

The role of sentinel lymph node mapping in lower genital tract melanoma.

Vulvar and vaginal melanomas are rare cancers of the female genital tract and account for 1% to 3% of all melanomas diagnosed in women. Due to the rarity of the disease, few data are available on the clinical and pathologic features of these cancers. Furthermore, treatment options are generally based on extrapolations of the information available for the more common cutaneous counterparts. Surgery represents the mainstay of treatment for lower genital tract melanoma. Moreover, the role of sentinel lymph node (SLN) assessment is controversial because no prospective data are available. Data were collected from Medline, Embase, Web of Sciences and Scopus databases. On July 10, 2020, we used the search comprising the terms "vulvar melanoma," "genital melanoma" and "vulvovaginal melanoma" including only studies in which SLN biopsy was performed. Ten retrospective studies have been found. No randomized trials have been reported. The studies included 132 patients while only 63 (47%) undergone SLN. 99mTC with or without blue dye followed by ultrastaging was highly accurate and is currently the gold standard. Mean detection rate was 98.3%. No clear evidence supported the execution of back lymphadenectomy (after SLN mapping), in fact, extrapolating data from cutaneous melanomas of other sites, completion of lymphadenectomy does not confer a melanoma-specific survival advantage. Although the small amount of available data, sentinel lymph node procedure is feasible and capable of identifying patients who have occult lymph node metastases. However, the potential role of the sentinel lymph node procedure as an alternative method of lymph node staging in patients with vulvar or vaginal melanoma needs further investigation.

Mediastinal Tracheostomy With Vessel Transposition and Minimally Invasive Transhiatal Esophagectomy

As surgical outcomes and survival of patients with cancer improves, in particular patients with head and neck cancer would often develop multiple primaries. The limitations of radiation for repeated local therapy leave radical surgery as the only local option for some of these patients. Given the complexity of the issues at hand, these patients should be evaluated by a multidisciplinary team with expertise in otolaryngology, radiation oncology, medical oncology, and thoracic surgery. Mediastinal tracheostomy is rarely used, but it can be a useful tool in the management of these complex patients. When esophagectomy is performed in combination with pharyngolaryngectomy, a minimally invasive transhiatal approach can be used. Transhiatal esophageal mobilization is technically feasible with laparoscopy, and it obviates the need for thoracic incisions and patient repositioning in this already complex morbid procedure. Additionally, for cervical esophageal tumors, neither margins nor completeness of lymphadenectomy are sacrificed. We describe several critical steps of mediastinal tracheostomy and minimally invasive transhiatal esophagectomy for the management of these complex patients.
