Acute colonic pseudo-obstruction (ACPO) is characterized by significant colonic distension without a mechanical obstruction. We present a case of an 83-year-old male who developed ACPO following laparoscopic surgery for sigmoid volvulus. This report details the patient's postoperative journey, highlighting the diagnostic and management challenges e...
Objective: This study aimed to assess the short-term outcomes of right-sided colon cancer surgeries with intracorporeal anastomosis, comparing them to the conventional extracorporeal anastomosis.
Methods: 181 cases of laparoscopic right-sided colon resections performed between April 2018 and December 2021 for cStage I-III colorectal cancer were inc...
The sigmoid colon is an uncommon site for the origin of primary malignant lymphomas in the GI tract. Additionally, immunosuppressive agents, widely used in treating autoimmune diseases, have been associated with the induction of malignancies, including lymphoproliferative disorders. In this report, we present a rare case of GI perforation suggestin...
Background: The usefulness of preoperative lymph node metastasis diagnosis by 18F fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) in colorectal cancer management has been reported, but inadequate diagnostic accuracy precludes routine preoperative application. Therefore, the purpose of this study was to examine the facto...
An 83-year-old man with diarrhea was referred to our hospital in July 2019. Colonoscopy revealed a 4.0cm rectal carcinoma. A robot-assisted laparoscopic Hartmann operation was performed in October 2019. The patient was discharged 13 days after the procedure. Positron emission tomography-computed tomography conducted a year after surgery revealed a...
Introduction
Efficacy of open abdomen management with negative pressure wound therapy for enteroatmospheric fistula has been performed. But, few reports have shown its utility for enteroatmospheric fistula several years after onset.
Presentation of case
A 46 year-old woman underwent total colectomy due to total ulcerative colitis in her twenties....
We report two cases of laparoscopic repair of perineal hernias following previous laparoscopic abdominoperineal resection. Generally, repair with a mesh using a laparoscopic approach is useful in cases with few adhesions in the abdominal cavity. However, owing to the effect of previous surgeries, it is sometimes difficult to identify important stru...
A 55-year-old man who had undergone esophagectomy for esophageal cancer 4 years ago visited the emergency room complaining of severe epigastralgia. He had taken proton pump inhibitors for a gastric tube ulcer. Redness of the skin was seen on his precordium, and a computed tomography scan detected subcutaneous emphysema around the sternum.
He was di...
During thoracic cavity operations, it is difficult to obtain sufficient working space and good operative field visibility in patients with pectus excavatum because the space between the vertebral bodies and sternum is very narrow. Here, we report the successful treatment of esophageal cancer in a patient with pectus excavatum. A 77-year-old man wit...
Three-dimensional computed tomography (3D CT) enteroclysis or virtual enteroscopy is a novel technique
to explore the entire small bowel using a modified protocol of virtual colonoscopy by inflating the small
bowel with air. In our hospital, the procedure is performed routinely for cases with suspected gross lesions.
We performed 3D CT enteroclysis...
Colonoscopy is widely used for the diagnosis, treatment for colorectal lesions. Although iatrogenic perforation of the colon is rare, it can be fatal. With the recent improvements in laparoscopic surgical devices and techniques, laparoscopic repair of colonic perforations is now feasible, provided adequate bowel preparation is performed. Here, we p...

... Enteroatmospheric fistulas (EAF), a particularly complex subtype of enterocutaneous fistulas, pose significant challenges in surgical management. These complications, characterized by a high mortality rate of 42%, arise in patients lacking adequate skin coverage over the viscera, thereby creating a direct communication of enterotomy with the atmosphere [1][2][3]. Their treatment demands a multidisciplinary approach to ensure optimal outcomes, requiring significant commitment from the entire healthcare team. Initially, management focuses on four critical areas: controlling sepsis, correcting fluid and electrolyte imbalances, caring for the skin, and optimizing nutritional status [1,2,4,5]. ...
... GCN was classified by Veeramootoo et al., and for massive necrosis graded as grade 3 in this classification, emergency surgical removal of the gangrenous portion of the conduit has been strongly recommended [7]. Delay in re-intervention may lead to devastating events such as fistulation of the trachea, lung, or thoracic wall [8][9][10]. Only a small number of patients have been reported to have undergone conservative treatment [11]. ...

... When we encounter such complicated case, the narrow working space and operative visual field in the mediastinum makes it difficult to perform intrathoracic surgery. There have been only a few reports on thoracoscopic esophagectomy in patients with PE, which was performed in the left lateral decubitus position [3,4]. Herein, we report the first two cases of esophageal cancer complicated by PE that were treated with thoracoscopic esophagectomy in the prone position. ...
