Laparoscopic repair of intrathoracic liver herniation after traumatic rupture of the diaphragm

Laparoscopic correction of experimentally induced diaphragmatic rupture in dogs

PURPOSE

To describe the dog as a model for studying laparoscopic correction of experimental diaphragmatic ruptures.

METHODS

Five male dogs were used in this study. Under laparoscopic approach, a defect of 7 cm was created on the left ventral insertion of the diaphragm. Fourteen days after this procedure, the abdomen was explored using laparoscopic access and the diaphragmatic defect was corrected with intracorporeal suture. The dislocated organs, surgical time, and suturing time were recorded. Analgesia and clinical condition were monitored during the postoperative period.

RESULTS

All animals recovered well from the diaphragmatic rupture creation. After 14 days, abdominal organs (liver, spleen, omentum and/or intestine) were found inside the thoracic cavity in all animals. It was possible to reposition the organs and suture the defect by laparoscopic access in three animals. These animals showed excellent postoperative recovery. It was not possible to reposition the liver safely when it was friable.

CONCLUSIONS

Laparoscopic creation of diaphragmatic rupture in dogs is feasible. Dogs are a good model for training and studying the correction of experimentally created diaphragmatic rupture by the laparoscopic approach. A friable liver is a complicating factor that should be taken into account. Animals submitted to laparoscopic correction showed excellent postoperative recovery.

The feasibility and efficacy of laparoscopic repair for chronic traumatic diaphragmatic herniation: introduction of a novel technique with literature review

PURPOSE

Traumatic diaphragm rupture is a rare trauma that is easily overlooked. A missed diagnosis would result in chronic traumatic diaphragmatic herniation (CTDH). Surgical repair is the standard treatment that is conventionally performed by laparotomy or thoracotomy. Laparoscopic repair has been reported, but its efficacy remains controversial. In this study, we present our novel technique and experience of laparoscopic repair of CTDH and analyze the feasibility and effectiveness of this procedure.

METHODS

We conducted a prospective collection with retrospective review of patients with CTDH treated at Chang Gung Memorial Hospital, Taiwan, from 2000 to 2013. The demographic characteristics, surgical procedure, perioperative results, length of hospital stay (HLOS) and follow-up were record and analyzed.

RESULTS

There were 114 patients with traumatic diaphragm hernia, and 24 of them had CTDH with a mean age of 54.9 ± 13.3 years. The HLOS was 15.08 ± 8.17 days. Regarding the surgical method used, 19 patients had open surgery, and 5 patients underwent laparoscopic surgery. The demographic distribution, trauma mechanism, location and size of CTDH were comparable. In the laparoscopic group, the patients had a shorter median HLOS (6 days) than in the open surgery group (16 days; p = 0.002). There was no mortality or recurrence in both groups.

CONCLUSIONS

In this study and literature review, patients had laparoscopic repair with a smooth recovery. Laparoscopy provides good surgical exposure, allowing easy repositioning of the herniated content and a smooth repair of the defect without the morbidity of laparotomy. For CTDH, with caution, we can apply this technique with an acceptable result.

Traumatic intra-abdominal hemorrhage control: has current technology tipped the balance toward a role for prehospital intervention?

BACKGROUND

The identification and control of traumatic hemorrhage from the torso remains a major challenge and carries a significant mortality despite the reduction of transfer times. This review examines the current technologies that are available for abdominal hemorrhage control within the prehospital setting and evaluates their effectiveness.

METHODS

A systematic search of online databases was undertaken. Where appropriate, evidence was highlighted using the Oxford levels of clinical evidence. The primary outcome assessed was mortality, and secondary outcomes included blood loss and complications associated with each technique.

RESULTS

Of 89 studies, 34 met the inclusion criteria, of which 29 were preclinical in vivo trials and 5 were clinical. Techniques were subdivided into mechanical compression, endovascular control, and energy-based hemostatic devices. Gas insufflation and manual pressure techniques had no associated mortalities. There was one mortality with high intensity focused ultrasound. The intra-abdominal infiltration of foam treatment had 64% and the resuscitative endovascular balloon occlusion of the aorta had 74% mortality risk reduction. In the majority of cases, morbidity and blood loss associated with each interventional procedure were less than their respective controls.

CONCLUSION

Mortality from traumatic intra-abdominal hemorrhage could be reduced through early intervention at the scene by emerging technology. Manual pressure or the resuscitative endovascular balloon occlusion of the aorta techniques have demonstrated clinical effectiveness for the control of major vessel bleeding, although complications need to be carefully considered before advocating clinical use. At present, fast transfer to the trauma center remains paramount.

[Laparoscopic reconstruction in traumatic rupture of the diaphragm]

The authors report the case of a 63-year-old patient who was polytraumatized in a motor vehicle accident and suffered multiple traumatic injuries. Chest and pelvic fractures as well as left-sided diaphragmatic rupture with associated omentum herniation were diagnosed on CT scan. None of the injuries required urgent surgical intervention. After 10 days supportive therapy, elective laparoscopic reconstruction of the diaphragmatic hernia was performed. The authors discuss the role of laparoscopic diaphragm reconstruction.
