Trend of minimally invasive and open surgery experience of general surgery residents: Accreditation Council for Graduate Medical Education general surgery case log in Thailand.

Purpose: Minimally invasive surgery (MIS) offers patients several benefits, such as smaller incisions, and fast recovery times. General surgery residents should be trained in both open and MIS. We aimed to examine the trends of minimally invasive and open procedures performed by general surgery residents in Thailand. Methods: A retrospective review of the Royal College of Surgeons of Thailand and Accreditation Council for Graduate Medical Education general surgery case logs from 2007 to 2018 was performed for common open and laparoscopic general surgery operations. The data were grouped by three time periods, which were 2007-2010, 2011-2014, and 2015-2018, and analyzed to explore changes in the operative trends. Results: For Thai residents, the mean number of laparoscopic operations per person per year increased from 5.97 to 9.36 (56.78% increase) and open increased from 20.02 to 27.16 (35.67% increase). There was a significant increase in the average number of minimally invasive procedures performed among cholecystectomy (5.83, 6.57, 8.10; p < 0.001) and inguinal hernia repair (0.33, 0.35, 0.66; p < 0.001). Compared to general surgery residents in the United States, Thai residents had more experience with open appendectomy, but significantly less experience with all other operations/procedures. Conclusion: The number of open and minimally invasive procedures performed or assisted by Thai general surgery residents has slowly increased, but generally lags behind residents in the United States. The Thai education program must be updated to improve residents' technical skills in open and laparoscopic surgery to remain competitive with their global partners.

Successful Conservative Treatment of an Elderly Patient with Corrosive Proctocolitis.

Corrosive proctocolitis has occurred after accidental contamination of endoscopes in most patients. But accidental administration of corrosive agents for bowel cleansing can occur. The agents implicated for chemical colitis is 15% hydrochloric acid and 2% ethoxylated alcohol. We present a case of corrosive proctocolitis, present with anal pain and bloody diarrhea. Endoscopy revealed edema, erythema, and friability of the colonic mucosa. An experience of successful nonoperative treatments has been demonstrated.

Spontaneous Intramural Duodenal Hematoma: Pancreatitis, Obstructive Jaundice, and Upper Intestinal Obstruction.

Nontraumatic intramural duodenal hematoma can cause upper gastrointestinal tract obstruction, upper gastrointestinal hemorrhage, jaundice, and pancreatitis and may be present in patients with normal coagulation. However the pathogenesis of the condition and its relationship with acute pancreatitis remain unknown. We present a case of spontaneous intramural duodenal hematoma and a case of successful nonoperative treatments.
