Intersphincteric resection (ISR) has rapidly increased worldwide including laparoscopic surgery. However, there are some concerns for the definition of ISR, surgical technique, oncological outcome, anal function, and quality of life (QoL). The aim of the present study is to evaluate those issues. A review of this surgical technique was carried out by searching English language literature of the PubMed online database and appropriate articles were identified. With regard to open‐ISR, the morbidity rate ranged from 7.5% to 38.3%, with lower mortality rates. Local recurrence rates varied widely from 0% to 22.7%, with a mean follow‐up duration of 40–94 months. Disease‐free and overall 5‐year survival rates were 68–86% and 76–97%, respectively. Those outcomes were equivalent to laparoscopic‐ISR. Surgical and oncological outcomes of ISR were generally acceptable. However, accurate evaluation of anal function and QoL was difficult because of a lack of standard assessment of various patient‐related factors. The surgical and oncological outcomes after ISR seem to be acceptable. The ISR technique seems to be valid as an alternative to abdominoperineal resection in selected patients with a very low rectal cancer. However, both necessity for ISR and expectations of QoL impairment as a result of functional disorder should be fully discussed with patients before surgery.
A careful preoperative endoscopy is necessary for patients who are at high risk of SMGC, and minimally invasive treatment may be indicated in some cases.
Hydrocele of the canal of Nuck, also called the “female hydrocele,” is a rare developmental disorder in females. This entity is now believed to be more common now in comparison with previous reports; however, it is still an unfamiliar problem for physicians. The processus vaginalis accompanies the round ligament through the inguinal canal into the labium majus. This evagination of the parietal peritoneum forms the canal of Nuck in the female. The canal of Nuck normally loses its connection with the peritoneal cavity during the first year of life, but can result in a hernia or hydrocele when the connection of the canal of Nuck fails to close. Here, we present the case of a 43-year-old female who complained of swelling in the right inguinal region. Coronal and axial magnetic resonance imaging (MRI) revealed a cystic mass lesion with an irregular shape in the right inguinal region, and smaller cystic lesions extending alongside the right round ligament were also identified in the right side of the pelvic cavity. Magnetic resonance (MR) hydrography revealed the uninterrupted cystic lesion from the inguinal region to the pelvic cavity, with constrictions at the internal and external inguinal rings. These MR findings proved to be incredibly useful for surgical planning.
Proximal gastrectomy (PG) is a widely accepted, efficient treatment for upper-third early gastric cancer. However, it is associated with reduced quality of life (QOL) following surgery, and cancer recurrence in the remaining stomach. Various reconstruction methods have been proposed, but the optimal method has yet to be determined. We investigated the clinicopathological characteristics, reconstruction methods, and postoperative complications in 101 cases of PG, and additionally compared 93 cases of early gastric cancer treated by PG, and 38 cases treated by total gastrectomy (TG). We found that esophagogastrostomy was superior in terms of operation time, intraoperative blood loss, and postoperative hospital stay, while no significant differences were observed in postoperative complications compared with jejunal interposition or jejunal pouch interposition. We found more cases of multiple gastric cancers and advanced-stage cancer in the TG group than in the PG group. The TG group also had a significantly higher proportion of cases with large tumor diameters, low degrees of differentiation, many lymph node metastases, and advanced-stage disease. There were no differences in the recurrence rate or survival rate between the PG and TG groups. The PG group also showed significantly better results in operating time, intraoperative blood loss, and postoperative complications, with a tendency toward shorter hospital stays. In conclusion, PG is a curative but less invasive treatment for upper-third early gastric cancer, and esophagogastrostomy can be considered the most satisfactory reconstruction method following PG.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
