“…Future investigations should identify the ideal technique Our previous studies demonstrated that laparoscopic Finney pyloroplasty is technically more demanding than Heineke-Mikulicz pyloroplasty or Ramstedt pyloromyotomy [12,13], but allows for a greater increase in pyloric diameter [11]. As this report shows, mechanical suturing has markedly simplified the gastroduodenal anastomosis.…”

“…Laparoscopic pyloroplasty has been described as a successful technique after failed pyloric dilation [2] and in experimental studies [12,13]. It provides treatment while preserving the benefits of a minimally invasive surgery [2], and the possibility of decreasing gastric emptying time suggests a potential clinical application for this approach.…”

“…Fluoroscopic studies were performed 15 days and 1 month after surgery using the technique we previously described in dogs [12,13]. After 1 month, an endoscopic exploration and a postmortem laparotomy with intraoperative ultrasonography were performed to evaluate the results of the intervention.…”

The efficacy of laparoscopic surgery in the treatment of chronic duodenal ulcer has been demonstrated using minimally invasive approaches. This study aimed to evaluate the technical feasibility of laparoscopic Finney pyloroplasty in six dogs. Under laparoscopic guidance, the anastomosis was created using mechanical devices (n = 3) and combining a linear stapler device and intracorporeal suturing (n = 3). The operative time and complications were recorded. Evaluation of the anastomosis included studies of intraoperative and postoperative endoscopy and ultrasonography as well as the complete gastric emptying time. The animals were killed 4 weeks after surgery. Measurement of luminal diameter, amount of adhesion formation, degree of healing, and inflammation or fibrosis were evaluated in the postmortem studies. The operation was successfully completed for all the animals. No intraoperative or postoperative complications were observed. Gastric emptying was significantly enhanced in the postoperative period, as compared with the preoperative results. After 1 month, there was no evidence of anastomotic leak dehiscence at the gastroduodenal anastomosis. Luminal diameter was increased, and no abnormal findings were encountered during the postmortem abdominal exploration. The technical feasibility of performing a safe laparoscopic pyloroplasty in a dog model was demonstrated in this study.

“…This procedure, with an open approach, is in fact undertaken in cases of benign GOO, and is only rarely performed in the emergency setting since it is more technically challenging than the Heineke-Mikulicz pyloroplasty (20)(21)(22)(23). FP can be used particularly when the site of the perforation is too wide and located in D2, to ensure good caliber of the pylorus when no healthy tissue around the ulcer can provide good closure of the duodenal defect (18,24). As this is a single case report, further studies are required to define the long-term outcomes and/or compare LS to open surgery in perforated DU with GOO.…”

Pyloroplasty is currently reserved for emergencies (perforation, bleeding), but may occasionally be performed to treat benign gastric outlet obstruction (GOO). Historically, two techniques are available: the Mikulicz pyloroplasty, by which the pylorus is incised longitudinally and sutured vertically, and the Finney pyloroplasty, by which a U-shaped inverted incision is made in the second part of duodenum (D1-D2), followed by a side-toside gastroduodenostomy. We report our experience in this single case of laparoscopic Finney pyloroplasty (LFP) performed in the emergency setting for a woman with a perforated duodenal ulcer and severe loss of tissue in D1-D2. Due to the presence of severely inflamed perforation edges and the risk of duodenal narrowing with subsequent GOO, Finney technique was favored over direct ulcer repair. The patient achieved a full postoperative recovery free of complications, with a dynamic oral contrast study demonstrating good gastric evacuation. Review of the current literature revealed no similar cases, as LFP has only been performed in the canine model. Although LFP requires a specific surgical skill-set, we believe it can be effective and feasible in cases of duodenal perforation with significant loss of mural substance.

Abstract: Analysis of results of this study suggests that ultrasonography is useful for detecting relevant morphologic changes in the pyloric sphincter after pyloroplasty.
