Project description:ObjectiveThis study introduces and evaluates the feasibility, safety, and surgical outcomes of the in-bag power morcellation technique during single-port assisted (SPA) laparoscopic myomectomy in comparison with manual scalpel morcellation.MethodsThis is a retrospective review of a total of 58 patients who underwent SPA laparoscopic myomectomy employing in-bag power morcellation (n=27) or manual scalpel morcellation (n=31), performed between December 2014 and December 2016. Surgical outcomes, including total operation time, estimated blood loss, postoperative hemoglobin changes, postoperative hospital stay, postoperative pain (visual analog scale), perioperative and postoperative complications were evaluated.ResultsThe demographics and patient characteristics were similar between both groups. The median patient age was 34 years and median body mass index was 20.84 kg/m2. The median specimen weight was 110 g. The median operating time was 138 minutes. The median estimated blood loss was 50 mL and the median postoperative hemoglobin change was 2.2 g/dL. The median postoperative hospital stay was 2 days and the median postoperative pain scores were 5 after 6 hours, 3 after 24 hours, and 2 after 48 hours. Occult malignancy was not identified in any patients. There were no intraoperative complications such as LapBag ruptures or gross spillage.ConclusionIn-bag power morcellation for SPA laparoscopic myomectomy is feasible and safe, minimizing the risks of open power morcellation. There were also no statistically significant differences in surgical outcomes.
Project description:Sacrocolpopexy has been dubbed the “gold standard” repair for apical pelvic organ prolapse (POP). This study sought to determine a genetic cause for sacrocolpopexy failure by comparing genotypes from 10 women who suffered from early POP reoccurance after sacrocolpopexy surgery, versus 40 randomly selected women with long term success after the same procedure. We objectively defined early overt failure after robotic-assisted laparoscopic sacrocolpopexy as having a pelvic organ prolapse quantification system examination (POP-Q) of stage III or IV occurring in more than one compartment within six months after surgery. All medical records identified during this process were then reviewed by a panel of urogynecology attendings and fellows to select patients who were truly clinical outliers. By this method we identified 10 patients (cases) who experienced early overt surgical failure. We also randomly selected 40 controls from our research database which includes greater than 500 patients who underwent robotic-assisted laparoscopic sacrocolpopexy during the same time period and had been objectively and subjectively assessed for ≥ 12 months with surgical success at ≥ 12 months that did not undergo prolapse re-operation or re-treatment. Demographics and peri-operative details were compared between cases and controls. Exclusion criteria for controls included use of other graft material besides polypropylene mesh, prior surgery for prolapse involving graft material, and conversion to laparotomy. DNA from the 10 cases and 40 controls was isolated from buccal swabs and genotyped on a single nucleotide polymorphism (SNP) array that contains 250,000 markers (NspI 250K SNP array, Affymetrix, Santa Clara, CA). All women in this study identified as Caucasian. All subjects provided written informed consent to study participation and data release. This was a case-control study approved by the Institutional Review Board at the Atlantic Health System in Morristown New Jersey (R11-10-004).
Project description:Electromechanical morcellation-so called power morcellation-is a minimally invasive approach to remove bulky lesions such as uterine fibroids. The spread of benign and malignant tissue due to morcellation is a major concern that might limit the use of laparoscopic interventions. We present an in vitro evaluation of the safety characteristics of a four-port endobag with closable trocar sleeves, and describe physical properties of the bag that may or may not allow passage through the hole. In addition, we report our preliminary experience of this tool when used for laparoscopic supracervical hysterectomies. The behavior of the endobag during the extraction process was analyzed by extracting opened and re-sealed bags filled with 20 ml blue dye solution through a wooden template, with incisions measuring 10 to 24 mm. The endobag was used in 50 subtotal hysterectomies during the morcellation procedure. In the in vitro test, no dye loss was recorded for incisions measuring 11-24 mm. The mean force required to pull the bag through the template was inversely proportional to incision size. No bag rupture occurred during the surgical procedures. The mean time taken to prepare the bag for morcellation was 7.1 min (range, 4-14 min), the mean duration of subtotal hysterectomy was 53.4 min (range, 20-194 min). The mean weight of the removed body of the uterus was 113.8 g (range, 13-896 g), the mean weight of tissue and fluid remaining in the bag after morcellation 7.9 g (range, 0-39 g). In the in vitro setting, the improved endobag signifies greater patient safety during bag extraction, along with less tissue traumatization due to a smaller incision in the abdominal wall. The improved ergonomic features of the bag permit the insertion of three trocars in the lower abdomen and avoid closure of unused access ports. Our preliminary experience has shown that the device can be used under routine conditions. Failure rates will be evaluated in future studies.
Project description:Blunt abdominal trauma is associated with a bladder injury in 1.6% of cases. The patient's conditions and the specific diagnosis determine the best surgical approach, be it open, laparoscopic or robotic surgery. We present the diagnosis and laparoscopic management of a 31-year-old patient with intraperitoneal bladder rupture due to a traffic accident.

Project description:ObjectiveTo evaluate the efficacy and safety of an endoscopic bag during laparoscopic morcellation of leiomyoma or myomatous uterus.Materials and methodsA total of 48 patients with symptomatic leiomyoma were randomized for laparoscopic morcellation in two groups: group A with a specific endoscopic bag or group B without any bag. The primary outcome measure was the detection of smooth muscle cells from washing after power morcellation determined by peritoneal cytology and immunohistochemistry (IHC).ResultsCytology and IHC from group A did not revealed any smooth muscle cells, while 29% of cases (7/24) from group B were positive (p = .009). The duration of the surgical procedure was the same in both groups. The duration of positioning the bag did not change significantly during the study. Only in one case the use of the bag was difficult due to a low pneumoperitoneum.ConclusionsThe use of a morcellation bag is efficient to prevent the spread of smooth muscle cells during the morcellation of leiomyoma or myomatous uterus. This study confirms the feasibility and the safety of the laparoscopic inbag morcellation versus open morcellation.
Project description:BackgroundFollowing a 2014 safety warning (that laparoscopic power morcellation may increase tumor dissemination if patients have occult uterine cancer), hysterectomy practice shifted from laparoscopic to abdominal approach. This avoided morcellating occult cancer, but increased perioperative complications. To inform the national impact of this practice change, we examined the cost-effectiveness of hysterectomy practice in the postwarning period, in comparison to counterfactual hysterectomy practice had there been no morcellation warning.Materials and methodsWe constructed a decision tree model to simulate relevant outcomes over the lifetime of patients in the national population undergoing hysterectomy for presumed benign indications. The model accounted for both hysterectomy- and occult cancer-related outcomes. Probability-, cost-, and utility weight-related input parameters were derived from analysis of the State Inpatient Databases, State Ambulatory Surgery and Services Databases, data from the New York Statewide Planning and Research Cooperative System and New York State Cancer Registry, and published literature.ResultsWith an estimated national sample of 353,567 adult women, base case analysis showed that changes in hysterectomy practice after the morcellation warning led to a net gain of 867.15 quality-adjusted life years (QALYs), but an increase of $19.54 million in costs (incremental cost-effectiveness ratio = $22,537/QALY). In probabilistic sensitivity analysis, the practice changes were cost-effective in 54.0% of the simulations when evaluated at a threshold of $50,000/QALY, which increased to 70.9% when evaluated at a threshold of $200,000/QALY.ConclusionHysterectomy practice changes induced by the morcellation warning are expected to be cost-effective, but uncertainty in parameter values may affect the cost-effectiveness results.
Project description:The number of robotic inguinal hernia repair (RIHR) surgeries performed by younger surgeons and surgical residents has been growing worldwide. As a result, there has been growing interest in the pace at which surgeons develop their competencies. In Japan, the number of robotic surgeries with the double bipolar technique for gastric cancer is increasing. We devised an RIHR technique for a right-hand-dominant surgeon. This article describes the procedure and step-by-step instructions for this technique. We also assessed the learning curve of a surgeon experienced in the laparoscopic transabdominal preperitoneal (TAPP) approach and robotic gastrectomy. This was a retrospective review of 31 inguinal hernia patients (40 lesions) between December 2018 and April 2021 operated by a single surgeon. The cumulative summation technique (CUSUM) was used to construct a learning curve for robotic proficiency by analyzing the times for peritoneal flap creation, mesh placement, and peritoneal closure. The postoperative course, namely, the length of hospital stay, 30-d complications, and 30-d readmission rates, was evaluated. The CUSUM graph for the total time for each phase indicated an initial decrease at lesion 12 and another decrease at lesion 36, generating three distinct performance phases: learning (n = 12 procedures), competence (n = 24), and mastery (n = 4). Between the early and late periods, no significant differences in patient characteristics or surgical outcomes were found. The learning curve for this technique was divided into three performance phases, and the technique was safely achievable in 36 procedures by a surgeon with previous experience in laparoscopic TAPP.
