Well-leg compartment syndrome after laparoscopic surgery for rectal cancer: A case report

Preliminary comparative study of lower extremity pressure measurements under the conditions using former models and new lithotomy stirrups in rectal cancer surgery

BACKGROUND

This study aimed to investigate the effect of the use of new lithotomy stirrups-2 on the pressure dispersal on lower limbs, which may lead to the prevention of well-leg compartment syndrome (WLCS) and deep venous thrombosis (DVT), which are the most commonly associated adverse events with laparoscopic and robot-assisted rectal surgery.

METHODS

A total of 30 healthy participants were included in this study. The pressure (mmHg) applied on various lower limb muscles when using conventional lithotomy stirrups-1 and new type stirrups-2 was recorded in various lithotomy positions; 1) neutral position, 2) Trendelenburg position (15°) with a 0° right inferior tilt, and 3) Trendelenburg position (15°) with a 10° right inferior tilt. Using a special sensor pad named Palm Q®, and the average values were compared between two types of stirrups.

RESULTS

The use of new lithotomy stirrups-2 significantly reduced the pressure applied on the lower limb muscles in various lithotomy positions compared with the use of lithotomy stirrups-1. The most pressured lower limb muscle when using both lithotomy stirrups was the central soleus muscle, which is the most common site for the development of WLCS and DVT. In addition, when using the conventional lithotomy stirrups-1, the pressure was predominantly applied to the proximal soleus muscle; however, when using lithotomy stirrups-2, the pressure was shifted to the more distal soleus muscle.

CONCLUSION

These results suggest that the new lithotomy stirrups-2 is useful in reducing the pressure load on leg muscles, especially on the proximal to central soleus, and may reduce the incidence of WLCS and DVT after rectal surgery performed in the lithotomy position. Further clinical studies are needed to determine whether the use of lithotomy stirrups-2 prevents these complications in various clinical settings.

Well-leg compartment syndrome after robot assisted laparoscopic surgery for rectal cancer: A case report

INTRODUCTION

Lower limb compartment syndrome caused by improper positioning during surgery is called well-leg compartment syndrome. Although well-leg compartment syndrome has been reported in urological and gynecological patients, there have been no reports of well-leg compartment syndrome in patients who have undergone robot-assisted surgery for rectal cancer.

PRESENTATION OF CASE

A 51-year-old man was diagnosed with lower limb compartment syndrome by an orthopedic surgeon due to pain in both of his lower legs immediately following robot-assisted surgery for rectal cancer. Due to this, we started placing the patient in the supine position during these surgeries, and repositioned the patient to the lithotomy position following intestinal tract cleansing after rectal movement in the latter half of the surgery. This avoided the long-term effects of being in the lithotomy position. We compared the operation time and complications before and after the above measures were changed, in 40 cases of robot-assisted anterior rectal resection for rectal cancer performed at our hospital from 2019 to 2022. We found no extension of operation time and no occurrence of lower limb compartment syndrome.

DISCUSSION

There have been several reports describing the risk reduction of WLCS using intraoperative postural changes. An intraoperative postural change from a natural supine position without pressure which we reported is considered to be a simple preventive method for WLCS.

CONCLUSION

Changing the patient from the supine position to the lithotomy position during surgery may be a clinically acceptable countermeasure to prevent lower limb compartment syndrome.

Well Leg Compartment Syndrome: Pathophysiology, Prevention, and Treatment

The development of compartment syndrome involving the lower limb is a potentially devastating complication of prolonged surgery in patients held in the lithotomy position. Well leg compartment syndrome (WLCS) was recognized in 1953. The incidence of this condition has been reported to range from 0.20% to 0.03%. The mechanism of WLCS development in the absence of trauma appears to be related to prolonged hypoperfusion of the limb, pressure on the muscle compartments, and in some cases, reperfusion of the ischemic limb. This grave complication develops either during or immediately after prolonged surgery in which the patient was held in the Lloyd-Davies lithotomy or hemi-lithotomy position. Surgeons must be aware of the potential for WLCS development during prolonged surgery. Signs of developing WLCS include swelling, increased firmness of the muscle compartments, discoloration, and cooling of the limb. Preventive measures can be taken without contaminating the surgical field by returning the limb to the right atrium level. Once the diagnosis has been made, failure to prevent the development of WLCS requires extensile fasciotomy of each leg compartment to restore perfusion and relieve elevated intra-compartment pressures. This article reviews the pathophysiology, prevention, and treatment of WLCS.
