En bloc groin node resection reconstructed with external oblique flap for solitary metastatic cholangiocarcinoma: a case report

Cholangiocarcinoma requires complete surgical resection for cure. Even so, the recurrence and metastasis rates are high, and further treatment is typically through palliative systemic chemotherapy. Curative-intent resection of metastatic site may provide survival benefit in selected cases. However, there were no previous reports of groin node dissection in cholangiocarcinoma. We have reported the first case of intrahepatic mass-forming cholangiocarcinoma with isolated synchronous groin node metastasis, successfully treated with   resection of the liver mass followed by groin node resection, reconstructed with musculofascial flap. A 73-year-old man presented with right upper quadrant abdominal pain radiating to the right groin for two months. Magnetic resonance cholangiopancreatography revealed a 3.1 × 1.2 cm enhancing mass between hepatic segment 4 and the anterior peritoneum, invading the abdominal wall. Computed tomography of the abdomen revealed a 2.4 × 2.2 cm focal enhancing mass at the anterior aspect of the right lower abdominal wall, just anterior to the right inguinal ligament and iliac vessel. He underwent en bloc resection of hepatic segment 4, gallbladder, and anterior abdominal wall, and the histology result is cholangiocarcinoma. After systemic chemotherapy, he underwent en bloc resection of the right groin mass, reconstructed with external oblique musculofascial flap. The patient was able to achieve a 20-month recurrence free survival after the final operation. This case has demonstrated that in a carefully selected case, resection of distant metastasis cholangiocarcinoma can provide survival benefits, even in the rare site of metastasis.

The Effect of Presurgical Nasoalveolar Molding on Oronasal Fistula Following Primary Palatoplasty

OBJECTIVE

Presurgical nasoalveolar molding (PNAM) is widely used in cleft care protocol. This study investigated the correlation between PNAM and oronasal fistula after primary palatoplasty.

METHODS

A case-controlled study of 80 unilateral and bilateral complete cleft palate patients who underwent cleft palate repair were enrolled. Patients were divided into 2 groups: (1) no PNAM use and (2) PNAM use. The incidence of oronasal fistula and postoperative complications were compared between groups.

RESULTS

Forty patients in each group demonstrated the same baseline characteristics. The PNAM group showed a significantly lower postoperative oronasal fistula rate (15% versus 50%, P=0.003). Palatal cleft width wider than 12.5 mm increases the odds ratio of fistula formation by 1.19-fold (P=0.037), and the PNAM protected against postoperative palatal fistula formation (odds ratio 0.20, P=0.003).

CONCLUSION

Presurgical nasoalveolar molding can reduce postoperative oronasal fistula in wide-gap Veau type III and IV cleft palate.

Radiation ulcer treatment with hyperbaric oxygen therapy and haemoglobin spray: case report and literature review

OBJECTIVE

To explore the effectiveness of a combination of hyperbaric oxygen therapy and haemoglobin spray in radiation ulcer treatment.

METHOD

We reviewed the available literature and present a case report in which radiation ulcer was treated with a combination of hyperbaric oxygen therapy and haemoglobin spray.

RESULTS

After 30 sessions of hyperbaric oxygen therapy (2.4 ATA; 90 minutes each session) and administration of haemoglobin spray, the wounds showed gradual progress towards healing and a good granulating base was achieved. The wounds were closed after two months using a small split thickness skin graft.

CONCLUSION

A combination of hyperbaric oxygen therapy and haemoglobin spray was effective as a short course of treatment for radiation ulcers.

Indocyanine Green Angiography Precise Marking for Indeterminate Burn Excision: A Prospective, Multi-centered, Double-blinded Study

BACKGROUND

During burn excision, the clinical judgment whether to excise or not excise the area with indeterminate burn depth is difficult. Indocyanine green angiography (ICGA) has been reported to provide high accuracy in diagnosing indeterminate burns. This study aims to evaluate the complete wound closures in both short-term and long-term outcomes after using ICGA precise marking to guide indeterminate burn excision.

METHODS

This was a prospective, multi-centered, double-blinded, experimental study. The participants were admitted to the hospital with indeterminate burn wounds. ICGA precise marking was performed. The deep second-degree burn was painted, excised, and subsequently covered with skin grafts and measured on day 5. The superficial burns were measured on day 21. All wounds were followed-up at two months.

RESULTS

Thirty indeterminate burn sites were included in this study. Using ICGA precise marking, the overall rate of short-term complete wound closure, which combined superficial and deep burns, was found to be as high as 96.7% (29/30). The long-term complete wound closures at two months confirmed the short-term result and yielded 100.0% of complete wound closure. The complete wound closures between the short-term and long-term measurements were not significantly different (P > 0.999).

CONCLUSIONS

Using ICGA precise marking to guide indeterminate burn excision resulted in an excellent rate of complete wound closure and an insignificant difference between short-term and long-term wound outcomes. ICGA is a competent method to aid decision-making in burn surgery of the indeterminate area.

Function of Nasoalveolar Molding Devices in Bilateral Complete Cleft Lip and Palate: A 3-Dimensional Maxillary Arch Analysis

OBJECTIVE

This study aimed to observe and analyze the effects of nasoalveolar molding (NAM) on maxillary arch dimensions in patients with bilateral complete cleft lip and palate (BCLP) using 3-dimensional analyses.

DESIGN

Retrospective case series.

MATERIALS AND METHODS

Seventeen infants were treated using modified Khon Kaen University presurgical nasoalveolar molding devices (KKU-NAM). Dental casts were evaluated 3 dimensionally at 3 time points: pretreatment (T1), after using modified KKU-NAM for 2 weeks (T2), and before cheiloplasty (T3). Repeated-measures analysis of variance and Friedman test were used to compare the maxillary arch dimensions between time points.

RESULTS

Both sides of the cleft width, premaxilla deviation, and premaxilla protrusion had significantly reduced with the use of KKU-NAM. Premaxillary rotation had significantly improved, whereas the arch depth did not change significantly. Premaxilla width, posterior arch width, alveolar length, and height had significantly increased. The anterior arch width, intercanine width, and lateral sulcus width showed no significant changes. The intraclass correlation coefficient used to test the measurements indicated substantial reliability.

CONCLUSION

The modified KKU-NAM is an effective device for reducing the severity of bilateral cleft deformities, especially in the premaxilla area.

Birth Prevalence and Risk Factors Associated With CL/P in Thailand

INTRODUCTION

The objectives of this study were to obtain the birth prevalence of cleft lips and/or cleft palates (CL±P) and to identify potential associated risk factors in the population of the Northeast (NE) region of Thailand.

METHODS

The data were collected from October 1, 2012, to September 30, 2013, for infant deliveries with nonsyndromic CL±P in all hospitals of 4 provinces in the region. Workshops were conducted to establish diagnostic criteria, treatment guidelines, referral systems, data collection, and data reporting. All patients included in this study, including a case (the child born with cleft lip and palate [CLP]) and 2 control cases (2 following children born without CLP in the same hospital), completed a questionnaire regarding demographics, cleft characteristics, and factors of interest such as alcohol intake, smoking, vitamin use, and medication. Unadjusted and adjusted odds ratio were presented for the magnitude of associations between proposed risk factors and CL±P along with 95% CIs.

RESULTS

The overall birth prevalence of CL±P was 1.93 per 1000 live births. There was a significant difference in percentages of infants with low birth weights (P = .03), family history of CL±P (P = .01) in cases than controls. Mothers who took self-medication or a menstrual regulation supplement were more likely to have the child with CL±P (P = .01 adjusted).

CONCLUSIONS

The prevalence of CL±P in the NE Thailand was high. Low infant birth weight, family history of CL±P, and the use of self-medication or menstrual regulation herbal supplement was significant factors.
