Background
The laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair is a widely performed minimally invasive operation, but can present considerable ergonomic challenges for the surgeon. Our objective was to determine if a novel handheld software-driven laparoscopic articulating needle driver can mitigate these difficulties.
Methods
The video recordings of a consecutive series of TAPP cases by a single surgeon using the articulating device were compared with a series of cases using straight-stick laparoscopy. Two critical steps of the procedure were analyzed for time: mesh fixation and peritoneal suture closure. These steps were then compared before and after 10 initial consecutive cases to analyze whether the surgeon demonstrated improvement. A cost analysis was also performed between the two techniques.
Results
For mesh fixation, the surgeon averaged 227 s using tacker devices, compared with 462.4 s using the novel laparoscopic device (p = 0.06). For the peritoneal closure component of the operation, the surgeon improved the time per suture pass during closure from 60.61 s during the first 10 cases to 38.84 s after the first 10 cases (p = 0.0004), which was comparable to the time per stitch for standard laparoscopy (34.8 s vs 34.84 s, p = 0.997). Left-sided inguinal hernia repairs using the articulating device demonstrated a significantly longer time per stitch during peritoneal closure compared to the right side after first 10 cases (left: 40.62 s; right: 27.91, p = 0.005). Our direct cost analysis demonstrated that suture closure of the peritoneum using the articulating device was more cost-effective than tack fixation.
Conclusions
After only a 10 case initial experience, a laparoscopic hand-held articulating needle driver is comparable to standard laparoscopy to complete suture mesh fixation and peritoneal closure for TAPP inguinal hernia repair. Further, the feasibility of suture mesh fixation minimizes the need for costly tacker devices. This instrument appears to be a promising tool in this largely minimally invasive era of hernia repair.
In this case report we illustrate an atypical presentation of diaphragmatic hernia as a colocutaneous fistula. An 83-year-old female with history inclusive of hiatal hernia repair and multiple ventral hernia repairs presented with purulence from her left breast. CT scan was performed showing a colon-containing diaphragmatic hernia protruding between left-sided ribs, with an overlying left breast collection. She was taken to the OR, and after extensive lysis of adhesions, a large left diaphragmatic hernia was encountered with perforated colonic diverticulitis in the hernia sac extending to the colocutaneous fistula via the breast. The hernia sac was dissected down, the colon was mobilized, and a left segmental colectomy was performed to include the area of involved pathology, with primary anastomosis, and the diaphragmatic defect was repaired primarily. It is important to consider unusual presentations of diaphragmatic hernia, including any pathology involving any intraabdominal organs incarcerated within the defect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
