Neural Monitoring for Robotic Abdominal Wall Reconstruction

Halpern, David K; Liu, Helen H; Howell, Raelina S; Halpern, Robert M; Akerman, Meredith; Conlon, Joseph; Weidler, Christopher
Introduction/UNASSIGNED:Positioning-related neural injuries are an inherent risk in surgery, particularly in robotic-assisted abdominal wall reconstruction because of unique patient positioning and increased operative times. The implementation of intraoperative neurophysiological monitoring should be considered in such cases. Methods/UNASSIGNED:This was a two-armed study with one prospective intervention group and one retrospective control group. All patients underwent robotic abdominal wall reconstruction at an academic center. The prospective arm underwent robotic reconstruction from January through July 2019. The retrospective database reviewed patients who underwent the same procedure from August 2015 through July 2018. Factors assessed included: demographics (age, gender, body mass index, comorbidities), surgical details (American Society of Anesthesiologists class, procedure, operative time, positioning), outcomes (length of stay, 30-d readmission, reoperation), and any new-onset intraoperative or postoperative neuropathy. Patients were seen in the clinic postoperatively at weeks 1 and 6. Results/UNASSIGNED:Ten patients were included in the prospective arm. All received intraoperative neurophysiological monitoring using somatosensory evoked potentials. They were compared with 47 patients in the retrospective arm who underwent surgery without intraoperative neurophysiological monitoring. One position-related neural response from baseline was detected intraoperatively in the prospective arm; however, there were no peripheral neurological symptoms present postoperatively. Two patients in the control group developed transient peripheral neuropathies that resolved within 6 weeks. Demographics, surgical procedures, and length of surgery were similar in both groups. The prospective group had a higher rate of preoperative neuropathy and intraoperative use of vasopressors. Conclusion/UNASSIGNED:Incorporation of neurophysiological monitoring in robotic surgery is feasible and may lead to the prevention and reduction in positioning-related injuries.

Ascending the Learning Curve of Robotic Abdominal Wall Reconstruction

Halpern, David K; Howell, Raelina S; Boinpally, Harika; Magadan-Alvarez, Cristina; Petrone, Patrizio; Brathwaite, Collin E M
Background/UNASSIGNED:Robotic complex abdominal wall reconstruction (r-AWR) using transversus abdominis release (TAR) is associated with decreased wound complications, morbidity, and length of stay compared with open repair. This report describes a single-institution experience of r-AWR. Methods/UNASSIGNED:A retrospective chart review was performed on patients who underwent r-AWR by a single surgeon (D.H.) from August 2015 through October 2018. Results/UNASSIGNED:. Forty-one patients presented with an initial ventral hernia (74.5%) and 14 with a recurrent hernia (25.5%). Five patients had a grade 1 hernia (9.1%), 46 had a grade 2 hernia (83.6%), and 4 had a grade 3 hernia (7.3%) according to the Ventral Hernia Working Group system. Thirty-four (62%) patients underwent TAR, 21 (38%) patients underwent bilateral retrorectus release, and 10 (18.2%) patients underwent concomitant inguinal hernia repair. Mean operative time with TAR was 294 (range 106 to 472) minutes and 183 (range 126 to 254) minutes without TAR. Mean length of stay was 1.5 (range 0 to 10) days. Mean follow-up was 10.7 (range 1 to 52) weeks with no hernia recurrences. Seromas occurred in 6 (10.9%) patients, with 2 (3.6%) requiring drainage. Two (3.6%) 30-day readmissions occurred with no conversions to open or 30-day mortalities. Conclusions/UNASSIGNED:r-AWR with and without TAR is a safe and feasible procedure associated with a short LOS, low complication rate, and low recurrence even within the surgeon's learning curve experience.

Radiology-Pathology Conference: carcinosarcoma of the colon [Case Report]

Kim, Newrhee; Luchs, Jonathan S; Halpern, David; Davis, Elena; Donovan, Virginia; Weston, Shiobhan R; Katz, Douglas S
Carcinosarcomas are very uncommon tumors, which are comprised of both malignant epithelial and mesenchymal elements. They occur most commonly in the head and neck, respiratory tract, and female reproductive organs. In the gastrointestinal tract, they are most often found in the oropharynx, esophagus, and, to a lesser extent, in the stomach. Carcinosarcomas rarely originate from the colon, but when they do, they are extremely aggressive malignancies. We report the radiologic and pathologic findings of a patient with a carcinosarcoma believed to have arisen from the colon and which involved the adjacent mesentery and omentum.

Intestinal obstruction from midgut volvulus after laparoscopic appendectomy [Case Report]

Cuadra, S A; Khalife, M E; Char, D J; Wax, M R; Halpern, D
We present the case of a 30-year-old man who developed a small bowel obstruction from an acute midgut volvulus 8 days after undergoing a laparoscopic appendectomy. There was no evidence of congenital malrotation or midgut volvulus on the initial computed tomography (CT) scan or at laparoscopy. Subsequently, a midgut volvulus developed in the absence of congenital malrotation.
