Utility of Falciform Ligament in Abdominal Surgery: A Systematic Review

OBJECTIVE

The aim of the present systematic review was to assess current trends in use of falciform ligament in abdominal surgery.

BACKGROUND

The falciform ligament has been proposed in surgical literature as a suitable pedicle or flap with acceptable surgical outcomes; however, it is underutilized in abdominal surgery.

METHODS

We performed a literature search and meta-analysis. All English studies describing use of a falciform ligament were eligible for inclusion.

RESULTS

Of the 547 articles mentioning use of falciform ligament, 32 full text articles were included in this review. The majority were case reports (n = 14). The mremaining papers included retrospective analysis (n = 10), randomized control trials (n = 2), reviews (n = 3), and technique descriptions (n = 6).

CONCLUSION

The falciform ligament appears to be a safe and easily accessible natural tissue with a variety of surgical applications. It is most useful as a pedicle flap and could have benefit in foregut surgery including hepatic, pancreatic, biliary, gastric, and esophageal operations.

Thoracoscopic and laparoscopic approach for pleuroperitoneal communication under peritoneal dialysis: a report of four cases

BACKGROUND

Pleuroperitoneal communication (PPC) is a rare complication of continuous ambulatory peritoneal dialysis (CAPD) and often forces patients to switch to hemodialysis. Some efficiencies of video-assisted thoracic surgery (VATS) for PPC have been reported recently; however, there is no standard approach for these complications. In this case series, we present a combined thoracoscopic and laparoscopic approach for PPC in four patients to better assess its feasibility and efficiency.

CASE PRESENTATION

Clinical characteristics, perioperative findings, surgical procedures, and clinical outcomes were retrospectively analyzed. We combined VATS with a laparoscopic approach to detect and repair the diaphragmatic lesions responsible for PPC. We first performed pneumoperitoneum in all patients following thoracoscopic exploration. In two cases, we found bubbles gushing out of a small pore in the central tendon of the diaphragm. The lesions were closed with 4-0 non-absorbable monofilament sutures, covered with a sheet of absorbable polyglycolic acid (PGA) felt, and sprayed with fibrin glue. In the other two cases without bubbles, a laparoscope was inserted, and we observed the diaphragm from the abdominal side. In one of the two cases, two pores were detected on the abdominal side. The lesions were closed using sutures and reinforced using the same procedure. In one case, we failed to detect a pore using VATS combined with the laparoscopic approach. Therefore, we covered the diaphragm with only a sheet of PGA felt and fibrin glue. There was no recurrence of PPC, and CAPD was resumed at an average of 11.3 days.

CONCLUSIONS

The combined thoracoscopic and laparoscopic approach is an effective treatment for detecting and repairing the lesions responsible for PPC.

Video-assisted thoracoscopic surgery for pleuroperitoneal communication

Here we report the cases of five patients on continuous ambulatory peritoneal dialysis (CAPD) who developed hydrothorax because of pleuroperitoneal communication. Preoperative computed tomography (CT) peritoneography revealed penetrated sites on the diaphragm in all patients. All patients underwent video-assisted thoracoscopic surgery (VATS), and a dialysate containing indigo carmine was injected intraperitoneally through a CAPD catheter to confirm the fistula. In all patients, a thinned bleb was found at the center of the diaphragmatic tendon consistent with that noted on preoperative CT peritoneography. The bleb was resected using a surgical stapler in four patients, and the pleuroperitoneal communication did not recur. However, in one patient, the bleb was only covered with reinforcement agents and the hydrothorax recurred after CAPD. This study demonstrates that VATS treatment for pleuroperitoneal communication is safe and effective but that lesion resection would be more useful for preventing hydrothorax recurrence in patients undergoing CAPD.
