Ventilation efficiency after different incisions for cholecystectomy.

P Lindell, G Hedenstierna

Acta Chirurgica Scandinavica

|January 1, 1976

Summary

The muscle-splitting incision for cholecystectomy causes less postoperative breathing impairment than other surgical approaches. This approach may reduce lung complications and shorten hospital stays.

Area of Science:

Thoracic Surgery
Pulmonary Function Testing
Abdominal Surgery

Background:

Abdominal surgical incisions can impair postoperative pulmonary function.
Different surgical techniques may have varying impacts on respiratory mechanics.

Purpose of the Study:

To compare the effects of three different surgical incisions on postoperative pulmonary function after cholecystectomy.
To evaluate the recovery of respiratory parameters based on incision type.

Main Methods:

Pulmonary function tests including forced expiratory vital capacity (VC), forced expired volume in 1 second (FEV1), and peak expiratory flow (PEF) were measured.
Measurements were taken preoperatively and for four days postoperatively in 44 patients undergoing cholecystectomy.
Patients were divided into three groups based on incision type: muscle-splitting (MS), subcostal, and midline.

Main Results:

Postoperative VC and FEV1 decreased to 75% of preoperative values with MS incisions, versus 40-55% with subcostal or midline incisions.
Peak expiratory flow (PEF) decreased to 65% with MS incisions, compared to 50% with other incisions.
Patients with MS incisions showed faster recovery of VC and PEF within four days compared to those with subcostal or midline incisions.

Conclusions:

The muscle-splitting incision results in less postoperative reduction in ventilation efficiency compared to subcostal and midline incisions.
Utilizing the muscle-splitting incision may lead to fewer postoperative pulmonary complications.
This surgical approach has the potential to shorten patient hospital stays.
