Appendicitis Caused by an Endoluminal Clip

Management of gastric ascariasis is based on two simple principles: (1) extraction of the off ending worms and (2) institution of eff ective anthelmintic therapy so that worms downstream in the jejunum do not travel upstream. All our patients had eff ective relief of symptoms and pointed to the parasite as the cause of symptoms. Dyspepsia is a common symptom in the community. As a signifi cant percentage of dyspeptic patients had gastric ascariasis, this entity should be considered as a diff erential diagnosis of dyspepsia in endemic regions.

Esophageal intramural pseudodiverticulosis of the residual esophagus after esophagectomy for esophageal cancer

A 91-year-old man was referred to our hospital with intermittent dysphagia. He had undergone esophagectomy for esophageal cancer (T3N2M0 Stage III) 11 years earlier. Endoscopic examination revealed an anastomotic stricture; signs of inflammation, including redness, erosion, edema, bleeding, friability, and exudate with white plaques; and multiple depressions in the residual esophagus. Radiographical examination revealed numerous fine, gastrografin-filled projections and an anastomotic stricture. Biopsy specimens from the area of the anastomotic stricture revealed inflammatory changes without signs of malignancy. Candida glabrata was detected with a culture test of the biopsy specimens. The stricture was diagnosed as a benign stricture that was caused by esophageal intramural pseudodiverticulosis. Accordingly, endoscopic balloon dilatation was performed and anti-fungal therapy was started in the hospital. Seven weeks later, endoscopic examination revealed improvement in the mucosal inflammation; only the pseudodiverticulosis remained. Consequently, the patient was discharged. At the latest follow-up, the patient was symptom-free and the pseudodiverticulosis remained in the residual esophagus without any signs of stricture or inflammation.

Successful resection of metachronous para-aortic, Virchow lymph node and liver metastatic recurrence of rectal cancer

A 66-year-old female presented with the main complaint of defecation trouble and abdominal distention. With diagnosis of rectal cancer, cSS, cN0, cH0, cP0, cM0 cStage II, Hartmanns operation with D3 lymph node dissection was performed and a para-aortic lymph node and a disseminated node near the primary tumor were resected. Histological examination showed moderately differentiated adenocarcinoma, pSS, pN3, pH0, pP1, pM1 (para-aortic lymph node, dissemination) fStage IV. After the operation, the patient received chemotherapy with FOLFIRI regimen. After 12 cycles of FOLFIRI regimen, computed tomography (CT) detected an 11 mm of liver metastasis in the postero-inferior segment of right hepatic lobe. With diagnosis of liver metastatic recurrence, we performed partial hepatectomy. Histological examination revealed moderately differentiated adenocarcinoma as a metastatic rectal cancer with cut end microscopically positive. After the second operation, the patient received chemotherapy with TS1 alone for 2 years. Ten months after the break, CT detected a 20 mm of para-aortic lymph node metastasis and a 10 mm of lymph node metastasis at the hepato-duodenal ligament. With diagnosis of lymph node metastatic recurrences, we performed lymph node dissection. Histological examination revealed moderately differentiated adenocarcinoma as metastatic rectal cancer in para-aortic and hepato-duodenal ligament areas. After the third operation, we started chemotherapy with modified FOLFOX6 regimen. After 2 cycles of modified FOLFOX6 regimen, due to the onset of neutropenia and liver dysfunction, we switched to capecitabine alone and continued it for 6 mo and then stopped. Eleven months after the break, CT detected two swelling 12 mm of lymph nodes at the left supraclavicular region. With diagnosis of Virchow lymph node metastatic recurrence, we started chemotherapy with capecitabine plus bevacizumab regimen. Due to the onset of neutropenia and hand foot syndrome (Grade 3), we managed to continue capecitabine administration with extension of interval period and dose reduction. After 2 years and 2 mo from starting capecitabine plus bevacizumab regimen, Virchow lymph nodes had slowly grown up to 17 mm. Because no recurrence had been detected besides Virchow lymph nodes for this follow up period, considering the side effects and quality of life, surgical resection was selected. We performed left supraclavicular lymph node dissection. Histological examination revealed moderately differentiated adenocarcinoma as a metastatic rectal cancer. After the fourth operation, the patient selected follow up without chemotherapy. Now we follow up her without recurrence and keep her quality of life high.

A Novel Method for Real-Time Audio Recording With Intraoperative Video

OBJECTIVE Although laparoscopic surgery has become widespread, effective and efficient education in laparoscopic surgery is difficult. Instructive laparoscopy videos with appropriate annotations are ideal for initial training in laparoscopic surgery; however, the method we use at our institution for creating laparoscopy videos with audio is not generalized, and there have been no detailed explanations of any such method. Our objectives were to demonstrate the feasibility of low-cost simple methods for recording surgical videos with audio and to perform a preliminary safety evaluation when obtaining these recordings during operations. DESIGN We devised a method for the synchronous recording of surgical video with real-time audio in which we connected an amplifier and a wireless microphone to an existing endoscopy system and its equipped video-recording device. We tested this system in 209 cases of laparoscopic surgery in operating rooms between August 2010 and July 2011 and prospectively investigated the results of the audiovisual recording method and examined intraoperative problems. SETTING Numazu City Hospital in Numazu city, Japan. PARTICIPANTS Surgeons, instrument nurses, and medical engineers. RESULTS In all cases, the synchronous input of audio and video was possible. The recording system did not cause any inconvenience to the surgeon, assistants, instrument nurse, sterilized equipment, or electrical medical equipment. Statistically significant differences were not observed between the audiovisual group and control group regarding the operating time, which had been divided into 2 slots-performed by the instructors or by trainees (p > 0.05). CONCLUSIONS This recording method is feasible and considerably safe while posing minimal difficulty in terms of technology, time, and expense. We recommend this method for both surgical trainees who wish to acquire surgical skills effectively and medical instructors who wish to teach surgical skills effectively.

Internal hernia associated with colostomy after laparoscopic abdominoperineal resection

We herein describe a case with an internal hernia that developed after laparoscopic abdominoperineal resection for rectal cancer. The small intestine passed through the space between the sigmoid colon loop of the stoma and the abdominal wall. Internal hernias associated with colostomy are rare; however, the condition is an important complication, because it causes ischemia in both the herniated intestine and the sigmoid colon pulled through the abdominal wall as a stoma.
