RESUMO

Congenital diaphragmatic hernia (CDH) with a hernia sac and thoracic kidney is a very rare congenital anomaly. Recently, the usefulness of endoscopic surgery for CDH has been reported. We herein report a patient who underwent thoracoscopic repair of CDH with a hernia sac and thoracic kidney. A 7-year-old boy was referred to our hospital due to a diagnosis of CDH without clinical symptoms. Computed tomography showed herniation of the intestine into the left thorax and left-sided thoracic kidney. The key points of operation are resection of the hernia sac and identification of the suturable diaphragm under the presence of the thoracic kidney. In the present case, after repositioning the kidney to the subdiaphragmatic area completely, the border of the diaphragmatic rim was clearly visualized. Good visibility allowed resection of the hernia sac without damaging the phrenic nerve and closure of the diaphragmatic defect.

RESUMO

BACKGROUND: Hirschsprung disease (HSCR) is characterized by the absence of an enteric nerve system (ENS). To remove aganglionosis, bowel reconstruction is only a curative treatment. It is mandatory to identify the extent of aganglionosis during surgery. Raman spectroscopy is a nondestructive chemical analysis technique that provides detailed information regarding molecular vibrations. The purpose of this study is to detect the ENS using Raman spectroscopy in the human intestine for diagnosis of HSCR. METHODS: The Raman spectra of each layer of the gastrointestinal wall were collected from surgical specimens of the human rectum. Based on collected spectral data, principal component analysis was performed to determine the ENS. Subsequently, the Raman spectra of HSCR sections were analyzed. RESULTS: Molecular structures of the gastrointestinal wall were characterized by Raman spectroscopy. Raman spectroscopy could discriminate between ganglion and muscle layers, and the spectra of the border between muscle layers in the aganglionosis were collagen-associated peaks. Either absence on presence of ENS was also confirmed in HSCR material. CONCLUSIONS: Label-free detection of the ENS was successfully demonstrated using Raman spectroscopy. Since this is a preliminary study, the strategy which may contribute to differentiate between ganglionic and aganglionic segments using noninvasive techniques in HSCR should be evaluated by prospective studies in near future.

RESUMO

BACKGROUND: Obturator hernia (OH) is a rare but serious disease associated with high morbidity and mortality due to advanced patient age and comorbidities. This study evaluated the feasibility of a laparoscopic approach to OH. STUDY DESIGN: We retrospectively reviewed the records of 32 patients (median age 84 years; 31 women) with OH treated between 2003 and 2016. RESULTS: Five patients with incidental OH underwent total extraperitoneal (TEP) repair. Of 27 patients with incarcerated OH, 18 patients underwent laparotomy, 13 of which required bowel resection, and the remaining 9 patients underwent preoperative ultrasound-guided manual OH reduction. Of 6 patients with successful OH release, 3 and 2 patients underwent TEP and transabdominal preperitoneal repair, respectively, and 1 patient declined the operation. Three patients with failure underwent laparoscopic exploration and conversion to open operation for bowel resection. Comparing the open and laparoscopic groups, the median operation times were 67.5 minutes vs 124 minutes, respectively (p = 0.004); median postoperative stay was 19 vs 11 days, respectively (p = 0.028); and Clavien-Dindo grade II or higher complications tended to be lower (28% vs 8%, respectively; p = 0.359). Even in patients without bowel resection, the median postoperative stay was significantly shorter in the laparoscopic group compared with the open group (7.5 vs 15 days, respectively; p = 0.032). During a mean follow-up of 24.5 months, the 3-year recurrence rate for OH was 25% for non-mesh repair and 0% for mesh repair (p = 0.335). Three- and 5-year cumulative survival rates were 83% and 71%, respectively. CONCLUSIONS: Laparoscopic operations after ultrasound-guided manual reduction can be an alternative to emergent laparotomy in select OH patients.
