Small bowel volvulus after transabdominal preperitoneal hernia repair due to improper use of V-Loc™ barbed absorbable wire – do we always “read the instructions first”?

Highlights

• •Serious complications during routinely performed procedures due to improper use of V-Loc™ barbed wire can occur.
• •When used intraabdominally the V-Loc™ barbed absorbable wire needs to be shortened and the suture stump to be extraperitonealized.
• •Surgeons need to be aware of relevant “tricks and traps” of routinely performed procedures.

Abstract

Introduction

Transabdominal preperitoneal endoscopic hernia repair (TAPP) is part of primary surgical health care. While both, the reported recurrence rate and procedure specific morbidity are consistently low, rare serious complications occur.

Presentiation of case

A 36-year-old male patient developed bowel obstruction three days after both-sided TAPP for inguinal hernia repair. A computer tomography scan of the abdomen revealed a small bowel volvulus in the right lower quadrant of the abdomen requiring urgent revisional surgery. Intraoperatively, the small bowel and its mesenterial vessels were found to be twisted around a 5 cm long V-Loc™ barbed absorbable suturing wire. After successful laparoscopic adhesiolysis, removal of the wire and detorquing of the bowel conglomerate, resection of small intestine was not necessary. The patient's further postoperative recovery was uneventful.

Discussion

Due to the barbed configuration of the V-Loc™ wire, a gapless continuous suturing of the peritoneum without laparoscopic knotting is easily and fast to accomplish. In this case the recommendation of the manufacturer to shorten the wire was not strictly followed and neither had the suture stump been extraperitonealized in order to avoid such rare complications.

Conclusion

Surgeons need to be aware of relevant “tricks and traps” of routinely performed procedures and have to know all tools and material they use very well. This case may therefore increase our attention when it comes to little things which actually do matter.

1. Introduction

During the last decade endoscopic surgery has emerged as one of the ‘gold standard’ for inguinal hernia repair with the transabdominal preperitoneal hernia repair (TAPP) being the preferred choice in female patients [1]. This procedure is commonly performed and part of primary surgical health care worldwide. While both the reported recurrence rate and procedure specific morbidity are consistently low, rare serious complications can occur [2].

2. Case report

Herein, we describe the case of a 36 years old male patient who was referred to our tertiary care hospital three days after external both-sided TAPP for inguinal hernia repair. After a good initial recovery the patient developed abdominal pain and bowel obstruction. Further investigations showed increased blood inflammatory markers and absent peristalsis in the ultrasound. A computer tomography (CT) scan of the abdomen revealed a small bowel volvulus in the right lower quadrant of the abdomen (Fig. 1) requiring urgent revisional surgery.

Intraoperative, the CT finding was verified, with the small bowel and its mesenterial vessels being twisted around a 5 cm long V-Loc™ barbed absorbable suturing wire. After successful laparoscopic andhesiolysis, removal of the wire and detorquing of the bowel conglomerate, resection of small intestine was not necessary (Fig. 2A–D). The patient’s postoperative recovery was uneventful and the patient was discharged four days after surgery.

3. Discussion

The V-Loc™ wire can be used for closure of the peritoneum during the TAPP procedure. Due to its barbed configuration, a gapless continuous suturing of the peritoneum without laparoscopic knotting is easily and fast to accomplish [3].

A similar complication following V-Loc™ suture induced has not been reported in the context of endoscopic hernia repair yet. However, a review of the English language literature revealed few similar reports after intraperitoneal usage of this wire in the context of gynecological and colorectal surgery [4,5].

The common feature of all reported cases was that the recommendation of the manufacturer to shorten the wire (to the length of not more than 2 cm) was not strictly followed and neither had the suture stump been extraperitonealized in order to avoid such rare complications.

4. Conclusion

The key message of this case is as simple as crucial. Surgeons need to be aware of relevant “tricks and traps” of routinely performed procedures and have to know all tools and material they use very well. This case may therefore increase our attention when it comes to little things which actually do matter.
