Asymptomatic intrapelvic meningocele is rare. Here, we report the case of a 30-year-old Chinese man who underwent sigmoidectomy due to megacolon. During the operation, an intrapelvic cyst was found and resected. Meningocele was confirmed by histological examination. The patient recovered well postoperatively with the exception of liquorrhoea. Conservative therapy was initiated, including draini...

Intussusception is uncommon in adults. To our knowledge, synchronous colocolic intussusceptions have never been reported in the literature. Here we described the case of a 59-year-old female of synchronous colocolic intussusceptions presenting as acute abdomen that was diagnosed by CT preoperatively. Laparotomy with radical right hemicolectomy and sigmoidectomy was undertaken without reduction ...

Sigmoid volvulus is a rare, but serious, complication that can occur during pregnancy. We present a case of a 33-year-old pregnant female in the third trimester with a sigmoid volvulus. Detorsion of the volvulus was performed during colonoscopy. The patient underwent an elective sigmoidectomy at a later date. Prompt diagnosis of the volvulus sigmoid is critical to minimize fetal and maternal mo...

A 54-year-old woman presented a massive hematochezia 7 days after sigmoidectomy. Repeated colonoscopy and angiography failed to locate the site of bleeding and Hartman's operation was performed. Rebleeding from the rectum on the day of operation occurred and pulsate arterial bleeding with minimal surrounding ulcer 1 cm above the pectinate line was observed. Screlotherapy with ethanol and electr...

症例は64歳，男性．S状結腸癌（S，cT3N0M0，cStage IIa）の診断で腹腔鏡下S状結腸切除術（DST吻合）を施行した．特に合併症なく第7病日に退院したが，第24日病日に腹痛を主訴に当院を受診した．来院時に施行した腹部単純X線写真では下行結腸を起点に著明な結腸の拡張を認めた．腹部造影CTでは吻合部口側の結腸が吻合部に嵌頓していたため，DST吻合部の腸重積と診断した．内視鏡的整復も困難であったため，同日腹腔鏡下で緊急手術を行った．術中所見では口側結腸が吻合部に強固に嵌頓していたため，吻合部の切除・再吻合（DST吻合）を行った．再手術後は合併症なく第31病日に退院となった．術後病理検査では粘膜面の浮腫や線維化を認めたものの，腸重積の先進部となる器質的病変はなかった．腹腔鏡下S状結腸切除後のDST吻合部腸重積の症例は稀な病態であると考えられ，若干の文献的考察を加えて報告する．
