Purpose
We aimed to investigate the difference in the surgical outcome based on whether the assistant overcame the mirror image in laparoscopic colorectal surgery.
Methods
Three hundred patients who underwent laparoscopic colorectal surgery performed by single operator were divided into 2 groups. Based on the assistants’ experience, patients who underwent surgery involving 1 of 6 residents with an experience of fewer than 30 surgeries each were classified into group 1. Patients who underwent surgery involving a single fellow as an assistant with an experience of over 1,000 surgeries were classified into group 2. According to the type of surgery, patients were divided into left and right colon resection groups and the surgical outcome of groups 1 and 2 was investigated.
Results
Group 2 exhibited shorter operation time, less bleeding, shorter postoperative hospital stay, lower open conversion, and anastomotic leakage rate than group 1. In right colon resection, the operation time was shorter in group 2. In left colon resection, group 2 exhibited shorter operation time, less bleeding, shorter postoperative hospital stay, and lower anastomotic leakage rate. In the multivariate analysis, the assistant was a factor affecting the operation time in the entire surgery.
Conclusion
Assistants’ reverse alignment surgical skill proficiency was a factor affecting the operation time.

Abstract PDF

Common causes of lower gastrointestinal bleeding include diverticular disease, vascular disease, inflammatory bowel disease, neoplasms, and hemorrhoids. Lower gastrointestinal bleeding of appendiceal origin is extremely rare. We report a case of lower gastrointestinal bleeding due to angiodysplasia of the appendix. A 72-year-old man presented with hematochezia. Colonoscopy showed active bleeding from the orifice of the appendix. We performed a laparoscopic appendectomy. Microscopically, dilated veins were found at the submucosal layer of the appendix. The patient was discharged uneventfully. Although lower gastrointestinal bleeding of appendiceal origin is very rare, clinicians should consider it during differential diagnosis.

Abstract PDF

A transomental hernia through the greater or lesser omentum is rare, accounting for approximately 4% of internal hernias. Transomental hernias are generally reported in patients aged over fifty. In such instances, acquired transomental hernias are usual, are commonly iatrogenic, and result from surgical interventions or from trauma or peritoneal inflammation. In rare cases, such as the one described in this study, internal hernias through the greater or lesser omentum occur spontaneously as the result of senile atrophy without history of surgery, trauma, or inflammation. A transomental hernia has a high postoperative mortality rate of 30%, and emergency diagnosis and treatment are critical. We report a case of a spontaneous transomental hernia of the small intestine causing intestinal obstruction. An internal hernia with strangulation of the small bowel in the lesser sac was suspected from the image study. After an emergency laparotomy, a transomental hernia was diagnosed.
